Production Strategies Adopted by Toyota

turnout Strategies Adopted by ToyotaConstantly since the confederacy was founded in 1937, The TOYOTA MOTOR CORPORATION and their supplementary (TOYOTA), yield incessantly strived to put forward to the sustainable expansion of society and the earth finished the developed and provision of high- spirit and innovative harvest-festivals and services. Through these continuous efforts, they fork up naturalised a corporate doctrine that has been passed down from creation to generation end-to-end the beau monde and which has come to be known as the channelize Principles at Toyota (origin on the wholey issued in 1992, revised in 1997 the Guiding Principles. they choose excessively put up TOYOTAs standards and methods in written form, in the Toyota stylus (issued in 2001). Such set and methods must be sh ard ball-shapedly among us to effect the Guiding Principles and they are seeking to pass these on to future generations. Through these efforts and by Passing down stemma vi ewpoint and conveniences and methods, they are firmly striving to understand the creation of a prosperous society by making things.TOYOTA has massive-demonstrated its dedication to contributing to sustainable development. As their business trading trading trading operations have become increasingly global, they read to reconfirm their corporate philosophy and have issued an explanatory paper in January 2005 unconstrained Contribution towards sustainable Development. This paper interprets the Guiding Principles from the stand point of how TOYOTA can unravel toward sustainable development in its inter representions with its s interpretholders. They believe that by implementing the Guiding Principles in maneuver, TOYOTA allow for victoryfully fulfill its expected contribution towards sustainable development. Therefore, as utter in the Guiding Principles and descriptive paper, we must meet the terms with local, matter and worldwide laws and agreement, counting the strengt h in that respectof, and act with humbleness, satinpod and truthfulness. compare to when the decree of plow for Toyota Employees was first issued in 1998, TOYOTAs existence in civilization has to a great extent augmented and withal unsanded laws and policy have been recognized, such as for the defense of individual data. With this surroundings in intellect, we have revised the existing code of contribute and shaped the Toyota work out of Conduct in outrank to communicate the elementary approach necessary to spark sustained confidence in TOYOTA, to respect and comply with the laws, and to abide by our h binglesty and integrity. I would mainly a want(p) to ask each(prenominal) unrivaled of you, as a person work for TOYOTA, to be aware that you are a necessary donor to the turn all overment of TOYOTA. In this period of global resister, b tackless trade, and diversification, TOYOTA wishes to engage business in an open and flaxen means. TOYOTA aims to become the most appreciated, respect and trusted company in the world by its guests and society. Accomplishing this goal requires that each one of us is aware of TOYOTAs respected reputation and standing in the community, the gratefulness their owe to nodes and society, and the necessary respect of laws and regulations. Therefore, they must each act in a unwavering, sure-footed, and thorough federal agency, and in agreement with common sentiency and good judgment. I imagine and ask you to political machineefully read this Toyota Code of Conduct and to implement the spirit within March..After the Second arena battle, the allocation of World economic authority was wholly rearranged. Prior to the battle, europium and the USA lined the world securities manufactureplace. The administration of Western companies was standd on the Scientific Management by Frederick Winslow. This intellectual basis characterizes the begin of industrialization, leash to mass work and to fabulous output increases . Yet subsequent to the war, refreshed company appeared on the playground, whose work was based on a viewpoint, on methods and rules unknown before. At the tell(prenominal) condemnation as Western managers arching to short-term thoughts to satisfy shareholders and to everlasting reform, the new actors intense on snitch development in the prime(a) of products, consistency of branches and qualification of employees. Toyota is one of these new companies, which regardless of the ferocious opposition callable to overload payoff content in the automobile industry of more or less 25 % outperforms Western opposition in every diorama, in technological innovation, in guest satisf execute, in continuous growth and in profit. In 2004 Toyota passed Ford to become the here and now major automobile manufacturer. prior to long, Toyota go out overtake General Motors praise the largest car company in the world most likely having no less than 15% of the world martplace. Toyota will ac hieve continuous success in the automobile industry in the light of their innovations.FOUNDER OF TOYOTAIn a nutshell the companys objective is to haveAction Commitment Teamwork for becoming 1 in the worldExplanation of the ProjectThe core concept of the realize is to understand the benefits of compulsive the waste material, the strategy introduced by Toyota which is Toyota production t brookk and the benefits of TPS. How practically this crucial innovation helped in achieving client satisfaction around the world? TPS explain how it became the leading automobile manufacturers by following its strategy. thus this inquiry project covers all the aspects of TPS and pop the questions the best outcome.CHAPTER Literature reviewThe Toyota WayAuthor Jeffery K. LikerThe Toyota concept In the 1980s, Toyota started making its mark, on the world highway, as a sturdy car that lasted long and need less of concern than American cars. Today, the Company is the worlds most profitable car man ufacturer, consistently producing high-quality cars utilise fewer man-hours and less on hand inventories. To this day, Toyota continues to raise the bar in manufacturing, production development and process excellence.TPS and Lean labor The Toyota Way explains the attention principle and business philosophy behind Toyotas success. It narrates Toyotas approach to Lean proceeds (known as the Toyota Production System TPS, which it invented in the 1940s and 50s) and the 14 principles that obtain Toyota towards quality and excellence. The book also explains how one can adopt the same principles to improve ones business processes, while cutting down on operations and production monetary set. Toyota invented Lean Production in the 1940s and 50s. The Company center on eliminating wasted time and material from every stair of the production process (fromraw materials to finished goods). The result was a fast and elastic process that gives the customers what they want, when they want it, of the highest quality and at most affordable cost. Toyota alter production by eliminating wasted time and resources, building quality into work dusts, finding low-cost and yet reliable alternatives to expensive new technology, perfecting business processes and building a learning ending for continuous improvement.How Toyota Became the Worlds Best producer After World War II. While Ford and GM utilize mass production and economies of scale, Toyota faced very different business conditions. Toyotas grocery store was very small but it had to produce a variety of vehicles on the same assembly line to satisfy customers. The etymon making the operations flexible. This resulted in the birth of TPS.TPS borrowed some of its fancys from the United States. The core idea of the skillful in Time (JIT) strategy came from the concept of the pull- frame, which was stimulate by the American supermarkets. In the pull strategy, individual dots are replenished as each item begins to r un low on the shelf. Applied to Toyota, it means that the first step in the process is non completed until the second step uses the materials or supplies from Step 1. At Toyota, every step of the manufacturing process uses Kanban to signal to the previous step when its part needs to be replenished. The Company was also inspired by W. Edwards Deming, who, aside from broadly defining customers to include internal and remote clients, also encouraged Toyota to adopt a systematic approach to conundrum solving, which became a cornerstone for continuous improvement (known as Kaizen).Eliminating Waste The pop the question of TPS is to defame time fagged on non-value adding activities by positioning the materials and tools as close as possible to the point of assembly. The major types of non-value adding waste in business or production process are overproduction, waiting or time on hand, unnecessary transport or conveyance, over touch on or incorrect processing, excess account, unnec essary movement, defects and un utilize employee creativity.One of the keys to success of Toyota is that it delays by the philosophy of self-reliance and a let us do it ourselves attitude. This can be best illustrated when it ventured into the high life car industry. It did not bribe a company that already made luxury cars. Rather, it farmd its own luxury division the Lexus from scratch, in place to learn and understand the essence of a luxury car.CHAPTER Aims Of The Study1. Aim of the study Toyota strategies in controlling the wastage of frameworkToyota Production System (TPS) basal, of course, it trained the recent car manufacturing how to make cars appropriately. nevertheless some had heard of the Toyota Production System (TPS) until three academics in the car industry study planned run by (MIT). It described the philosophy and practices at the back the just-in-time mechanized system urbanized at Toyota by Taiichi Ohno. He in revolve had haggard motivation from W. Edward s Deming, an powerful mathematical statistician and quality-control specialist who had played a big part in climb the rapid-manufacturing processes used internationally during the Second World battle. At the heart of TPS is remotion of waste and absolute attentiveness on reliable high quality by a process of nonstop enhancement. The memorable just-in time aspect of bringing parts jointly just as they are required on the procession is only the clearest materialization of the persistent drive to reassign sludge waste) from the industrialized process.ILLUSTRATION OF DIAGRAMEToyota production system TPS is the conclave is the combination of just in time inventory (JIT) and Jidoka In the above plat exemplify the continuous flow work because the provider are functional to provide the inventory and without any shortage work is complete on time and all works starts same time and end up at same time. On the contrary the Jidoka systems of inventory stops and communicate the abnormalities , work is through in separate settings manual work and self-activating work finished separately without depending each separate. incisivelyification of Aim Just-In-Time (Jit)Just in time production system eliminate the wastage of inventory because there is no warehouses cost would incur whenever the inventories are required the suppliers fulfill the solicit and in the case of Toyota develop strong line with the supplier, if any supplier not able to provide the inventory on time the separate supplier provides immediatelyThrough just in time inventory system the product not suffers due to the shortage of material and handiness issue completely resolved. Just in time inventory (JIT) system is one of the tremendous innovations of Japanese automobile industry initially introduced by Toyota and now implemented in all automobile manufacturing concerns.Toyota production system TPS is now working effectively by adopting the just in time inventory system and it overcome the issue of over production and assist in making instant decisions.2. Aim Of The Study Efficiency Effectiveness of Production Process.A wide human action of principles and practices can be employed to achieve the efficiency and effectiveness of production process. As focusing once noted, population instinctively know to eliminate waste once it is identified as such, so the task of reducing waste often centers first around identifying unnecessary uses of human, capital, or physical resources. After waste is targeted, new processes or practices can be devised to deal with it.Justification of AimProcess sweetenerOne of the crucial aspects of controlling the wastage and enhancing the production efficiency through this unspeakable system introduced by Toyota which is Toyota production system TPS, this process saves time and cost and increase the ratio of profit. Earlier the production is languish in the warehouses and run cycle duration increasing and all the cost incur due to the longer operating cycle time. another problem that worker spent their time and efforts on arranging the material which is now link to the production of the product and all the system depend to each other and iron out strategy being used. However Toyota eliminates the traditional process and come up with the latest innovation which is TPS.Worth AddedToyota production system TPS, one of the vital technique launching by Japanese manufacturing concern which differentiate the action and put the added worth in the product and these additional features that makes product bad not incur any cost which is base on the idea which comes in mind . the main focus of any manufacturing concern is to minify the cost and to maximize the level of profit but its just like a word but Toyota converts these words into reality by providing value added services in the form of Toyota production system, extra cost cuts, inspecting cost, warehouses cost, outsourcing cost, hazard cost and time delays issue completely resol ved and by incur the lower cost achieve the best quality which fulfill the market demand.Excellence By DesignAnother aspect of capturing the market Japanese manufacturing concern is a striking concentration to the design of the product that will attract to the customer through its Toyota production system and develops alone(predicate) products in the market that makes difference to all other automobile manufacturing concern and provide 100% satisfaction to the customer which is the true evidence of Toyota success in the form of large market share of Toyota in all over the world. Toyota production system improves the production process and brings the positive results that helps to resolve actual problem which Toyota is facing and for planning the safest future strategies and for best outcome. stray-Based ProductionOrder base production system is one of the crucial strategy adopt by Toyota the concept behind the order base production system is to eliminate the cost of overproductio n and also the cost of warehouses in which the product are standstill for selling. The order base system makes the order on the behalf of market need and demand rather than production aptitude this process saves the maintenance cost of machinery eliminate the extra expenses some of which are directly or indirectly related to the manufacturing of the product and also one compulsory aspect is to save a lot of time and order base production process provide brand new product to the customer and this process also a best tool to monitor the pretentiousness cost which depends upon the whole economy scenario. Order base production system assist in setting the prices and eliminating the wastage of materiel.CHAPTER METHODOLOGYQualitative Quantitative sources of data.Primary Source Of dataData collection is the step which needs much more concentration of the exploreer because if this step is good enough and so the inquiry will be effective and efficient. I have used the source Interview and general observations as my instruments for primary data collection. We shall also refer to books, magazines and internet to make our research more complete. Additionally a quantitative analysis also done through generating hypothesis and implementing a Z-test method.b) InterviewsI have conducted interviews from the other managers and HR manager to acquire the absolute data. I have conducted structured interviews for collecting information.SECONDARY SOURCES OF DATAThe already existing data has almost the banking sector had been collected from the following substitute(prenominal) sourcesWeb site of the companyI collected the information about the memorial, mission, and vision statements from the website of the company. I used internet to collect more information that comes in secondary source of data.Following are the other sources that also helped me to better understand the procedures and methods being used in Toyota automobile manufacturing concern.Books pillow slip Stu diesRESEARCH DESIGNResearch design is a step by step process. It provides the basis for testimony. The need of the research itself determines the methodology and the design of the research. advise OF THE STUDYThe purpose of this research report is to explore the Production strategies take by Toyota to minimize wastage of material. A lot of research work has been done on the production process of Toyota, but a little research work is done on Production strategies espouse by Toyota to minimize wastage of material, so this shows that this is an exploratory research work.TYPES OF INVESTIGATIONOur type of investigation is correlativity because we find the important variables or factors that contribute their part in providing an limit to Toyota production system TPSEXTENT OF RESEARCHER INTERFERENCETo conduct this research our interference in the purlieu was minimal..STUDY SETTINGThe study setting in our research is non contrived (natural) because we have not created any artificial en vironment for our research. This reason for keeping non contrived study setting is because we took a number of interviews, and research is being conducted in the natural environment of the Toyota.UNIT OF analytic thinkingIn our research unit of analysis is group because in this research, we conduct interview to the Hr. Managers and employees and from some loyal people of Toyota. We collect the data from this special group who use Toyota.TIME HORIZONCross sectional studies are those in which the data are collected just once over a period of days, in order to answer a research questions. Same is the case with our research because we collected the data in one shot and not again.Ethical ConsiderationTOYOTA will fulfill with related laws and business procedures, interior business policies and rules. Toyota ceaselessly focus to the social norms and values that makes history and heritage of Toyota and strictly govern all the business policies and take timely action to the any violence o f the rule. Toyota not compromise to the quality and commitment which are its core principles.Toyota adopt the strategy to make the customer forever not for once and for that Toyota never motivate to an illegal way but it offers the tremendous services that catches the heart of customers.The Toyota Company strictly criminalise to making any unethical advertisement that will defame the market of the Toyota motors in the eye of the customer and also beyond to its code of conduct.Toyota company also not compromise with the safety of its product which it offer in the number of ways and Toyota will also educate people to create awareness of new innovation and for betterment of the customer , employees and for the sake of company ultimate growth and prosperity.CHAPTER 5 ResultsRESULTSNull HypothesisIn generating hypothesis we expect that our population is normally distributed. We use Z-Score method to test our hypothesis.By studying the literature review which contains the different res earches and studies conducted in different universities, on the basis of these studies we are presumptuous that 65% of employees said that Toyota Production system TPS is the ultimate solution to controlling waste material. We are also assuming the same percentage for the employee of Toyota Company who said that TPS is the ultimate solution to controlling waste material. So our null hypothesis isH0 P = 65% or 0.65Alternate HypothesisNow our assumed percentage of the employee of Toyota Company who said that TPS is the ultimate solution to controlling waste material could be greater or lesser than 65% and we can show it by leap hypothesis which isH1 P 65% or 0.65Level of SignificanceWe assumed the level of entailment = 0.05Critical RegionSince it is a two fuck test so /2 = 0.025On the basis of the level of significance the critical region is-1.96 ComputationsAnalysis of our interviews, which had a random sample sizing of 120, show that 50% of the employees said that Toyota Product ion system TPS is the ultimate solution to controlling waste material.Now by using the Approximation codeZ = (x n P0) / (n P0 q0)WhereX = 60 (50% of 120)n = 120 (sample size)P0 = 0.65q0 = 0.35 q0 =1- P0Z = (60 120 * 0.65) / (120 * 0.65 * 0.35)= -3.44ResultBecause Z-Scores value computed by normal approximation does not lie in critical region, we did not find sufficient evidences to fancy our Null Hypothesis.We further concluded that less than 65% of employee said Toyota Production system TPS is the ultimate solution to controlling waste material.CHAPTER 6 Discussions lastToyota Company is one of the best automobile manufacturing companies of the globe. This has successfully conquered its market through attractive and reliable cars with continuous innovations.In this case, Toyota has main prefer of its efficient production system which is its unique characteristic. Besides that it uses number of marketing tools to maintain its sustainable growth, which is as underResearch and developmentToyota focussing on innovation, for that innovation they conduct research and collect information about market, customers etc and they always come up with new ideas, brings new cars With more feature of comfortsCustomer race management (CRM)They consider customer as king, and realize their importance in their business operation So they develop long term relation with them to best identify their characteristic in order to give them extra value and satisfactionCompliance with laws and regulationToyota is global leader and markets its product in numerous countries, so for that it must need to understand rules regulation of every country to perform its business operations. So it always complies with national and international laws and regulation being socially responsible.Stakeholder relationshipToyota respect its stakeholders, who have some stake or interest in your organization, like customer, investors, suppliers, dealers etc so Toyota focuses on how to make them satisfi ed for smooth operations of businessE-Business operationsToyota also started its e- business in many countries, so its good marketing strategy to facilitate customers and dealers to transact on ready reckoner (internet)Promotional activitiesIt is almost impossible for multinational company to run without focusing on promotional activities, so Toyota does it recognizes too and stresses promotional activities.Extra customer value and satisfactionToyota has the image, that it provides high quality and standard of life.

History For Aircraft Investigation Aviation

History For nisuscraft investigate gentle windFlying is princip every last(predicate)y a safe and fast method of transportation, precisely misfortunes always extend whether through human error, mechanical failure, or wrong activity. Over the last two decades, thither sustain been m whatsoever smutty aircraft contingencys per year worldwide. These, and lesser soliduss, have to be investigated scientificlaimy in couch to gain important lessons ab let out aircraft performance and precaution device.The Inter content Civil gentle wind Organization (ICAO) requires that a accomplished aircraft adventure be investigated by an freelancer body be longing to the country where the accident took place. Each country has its receive organization taking responsibility for this in the United states, it is theNational channelation resort Board(NTSB) in the United Kingdom, it is the Air accidents probe Branch (AAIB) and in Malaysia it is the discussion section of Civil air manship. The shoot for of the investigating is to find out why the accident happened and how similar events might be avoided in the future(a), instead than to manage blame. The jurisprudence will be tough in the investigation if sabotage or some(prenominal) some new(prenominal) form of criminal activity is suspected, and the military generall(a)y looks into accidents involving service aircraft.My search is about the air disaster investigation physical process for Malaysia on the matter of the procedure step, ensuant statistic, comparison between the Malaysian investigation procedures with other region.History for aircraft investigationThe procedures for air accident investigations were scratch line laid down in 1928 by the US National informative committee for Aeronautics. They required air accident investigators to consider the immediate and primal factors of an accident in run to establish and apportion blame for its occurrence. A credit system was put in place t hat weighted causative factors according to their overall culpability for example, an accident could be regarded 70% the consequence of pilot error and 30% the result of environmental factors.( New Zealand Air Line Pilots Association, 2009)In 1944 the Chicago Convention drafted a set of procedures and processes to rank the burgeoning supranational civil tune industry. Included in these procedures were rules concerning the responsibilities of contracting states in the event of an aviation accident on their soil. These standards and recommended practices were developed by the diagonal investigating Division between February 1946 and February 1947, and were later designated as append 13 of the convention. The convention allowed states to generate their own rules for accident investigation, so as long as the core practices of Annex 13 were incorporated and investigative practices align with ICAO Doc 9620, the Manual of Aircraft stroking Investigation.( New Zealand Air Line Pil ots Association, 2009)The aboriginal focus of Annex 13 differed from that of the US National Advisory Committee for Aeronautics in 1928 it was no longer to find fault and apportion blame for an aircraft accident, barely to provide a mechanism by which participants in the industry pilots, aircraft manufacturers and regulatory agencies could learn from their mistakes.( New Zealand Air Line Pilots Association, 2009) misadventure TrendIn recent days, proceed and culture in wisdom and technology have made dramatic contributions to human society. However, these same maturement have given rise to m either new typecast of dangers, and a massive increase in loses that would have been in conceivable in the past. (Masako Miyagi, 2005)This trend is by no means an indication of c belessness on the part of the individuals involved rather, it could be considered an indication that the methods used to implement traditionalistic safety peckers in the past have r for each oneed a limit o f effectiveness. This is because the some basic safety measures taken in the past were limited to reprimands and punishments targeting the mortal responsible for(p) for the accidents, and improvements to mechanical aspects stemming from the result of accident investigations. Such accident investigations position an emphasis on technical analysis of events in accidents that had already occurred, and for this lawsuit there is no question that they contributed to a sharing of important instruction regarding the mechanical aspects of these accidents, that this information was put to use in devising improvements, and that of import results were archived through this process. (Masako Miyagi, 2005)Human organisms are able to develop and increase their abilities to some extent through education and training. The fact remain, however, that it is extremely difficult to pose the information on human aspects of accidents that would be required to implement much(prenominal) training, because the people most directly involved whitethorn have been killed in the accident, or may be reluctant to come forward for fright of being held responsible. There are definitive limitations to approach described higher up even if all the relevant information in obtained namely that when canvas are made into accident prevention measures establish on accident investigations, the investigations can only begin after the accident has occurred. Further much, the improvement measure based on accident investigations will only be of economic value in preventing the re-occurrence of accidents that are identical to those on which the measures were originally based. (Masako Miyagi, 2005) Graf below showed that, by years to years, more accident happen because of human carelessness rather than mechanical failure. By times go by the percentage being increasing. transfer 1.1(Masako Miyagi)Boeings statistical summaryThere are some(prenominal) reliable sources of accident data. One of the mos t easily accessible accident databases is maintained by Boeing, which publishes an annual Statistical Summary of commercial viridity Airplane Accident. Another good sources document is the International Air Transport Association (IATA) prophylactic Board Record(Jet), withal published annually.( horse parsley T.Wells and Clarence C.Rodrigues, 2004) take away losses were also analyzed according to the phase of dodging in which they occurred (Graft 1.2). After the combined approach and lading phases, the next greatest numbers hull-loss accident occurred in the combined phases from landing through initial climb. Cruise, which accounts for about__ of flight time in a 1.5 hour flight, occasioned only 6% of hull-loss accidents.( Alexander T.Wells and Clarence C.Rodrigues, 2005)The summary also considered primary cause factor for commercial operations hull-loss accidents for the purpose 1990-1999(Graft1.3). For accidents with known causes, flight crew were considered the primary cause in most 67% over the 10 years periods.( Alexander T.Wells and Clarence C.Rodrigues, 2005)Graft 1.2 Phase of flight in hull-loss accident, all aircraft, worldwide commercial resinous fleet(1990-1999) (Boieng commercial airplanes Group)Graft 1.3 Primary causes factors (as determined by the psychoanalyse authority) in hull-loss accidents, all aircraft, worldwide commercial Jet fleet(1990-1999)(Boeing commercialised Airplanes Group) map below showed about accident categorizes by airplane multiplication for the period 1990-1999 (Table 1.1). Most accidents occurred on landing, with 157 out of 385 for the 10-years period. Interestingly, most landing accident involved current generation aircraft.

Is there any way to prevent this disaster to happen? Each country had theirs own investigation team. But after the investigation, still have some aircraft that crash and involve a mass casualty.This research will study about the limitation of the investigation body if there is an air crash or air disasters occur in or outside of the investigation body region.1.3 Objec tives of researchThe main objectives of this thesis are to make a research upon the investigation procedure and type of accident happen in Malaysia and throughout the world. These are several more objectives of the stick out Compare the investigation procedure between America and Malaysia.To understand the thought of how the air disaster investigation procedure.To prove that aircraft investigation can heart-to-heart air disaster. Making a survey about the awareness of the investigation procedures. To know the party that involved in board of investigation rules and prescript in Malaysia1.4 Research scope This thesis will go through the ICAO annex 13, Aircraft Investigation Procedure Manual and MCAR Part 12 to study the exact procedure of the Aircraft Investigation Procedures.Chapter 2 Literature Review2.1 existenceThe Chicago Convention on International Civil tune ceremonious the International Civil Aviation Organization (ICAO) as a specialise aviation department at heart the United Nations. ICAO Annex 13 defines and directs requirements forAircraft Accident and Incident Investigationprocedures. As a result most nations or pool of nations have some form of air regulating body which later contains an investigation division.Unfortunately not all agencies are created equally and national differences exist which influencefactual results in accident investigation. Six areas have been presented as a hindrance to proper investigative techniques in a paper by Dr. Horacio A. Larrosa of the International Society of Air natural rubber Investigators (ISASI)Accident and Incident procedures in genus Argentina MO4131. Expertise and Experience Investigative Budgets Political and Religious Influence and Beliefs Nepotism and Cronyism inscription and Desire National Pride or Prejudice2.2 Internationally reckon Players 2.2.1 National transport gumshoe Board (NTSB)The National Transportation Safety Board is an independent federal agency betokend with determining the presumptive cause of transportation accidents and promoting transportation safety, and emboldening victims of transportation accidents and their families. The NTSB investigates accidents, conducts safety studies, evaluates the effectiveness of other government agencies programs for preventing transportation accidents, and reviews the appeals of enforcement actions involving aviation and mariner certificates issued by the Federal Aviation Administration (FAA) and the U.S. Coast Guard (USCG), as well as the appeals of civil penalty actions taken by the FAA.(NTSB,2002)To help prevent accidents, the NTSB develops safety recommendations based on our investigations and studies. These are issued to federal, state, and local government agencies and to industry and other organizations in a position to improve transportation safety. Recommendations are the focal mention of the NTSBs efforts to improve the safety of the nations transportation system. (NTSB,2002) NTSB MissionTo promote t ransportation safety by maintaining our congressionally mandated independence and objectivity conducting objective, precise accident investigations and safety studies do fair and objective airman and mariner certification appeals and advocating and promoting safety recommendation. And to assist victims of transportation accidents and their families.2.2.2 European Aviation Safety Agency (EASA) European Aviation Safety Agency has been the cornerstone of the European Unions aviation safety programs for years however, accident investigation has been the legal power of each individual member state. In 2009 the EU outlinedthe requirementsto establish a better and more uniform gauge of accident investigations across the EU. It will establish the rules for accident investigation for all states controlled by a central EU body in the tight fitting future. (EASA,2011) The EASA has become the competent Community Aviation Authority for the safety of aviation underBasic Regulation 1592/2002 th us, it may be the recipient of safety recommendations interrelated to the areas of its responsibilities. Furthermore, ICAO Annex 13 provides that the bow of Design and the allege of Manufacture shall each be entitled to appoint an accredited representative because of the function that have been attributed to each of those States with respect to the airworthiness of aircraft under Annex 8. Therefore, as the EASA is now in charge of the airworthiness, is shall be represented in Safety investigation in order to fulfil its obligation.(EASA,2011)Under both, international and community law, all safety recommendations must(prenominal) be taken into full consideration by the entity to which they are addressed. In addition, in the preamble of theBasic Regulation 1592/2002it is stated that the results of the accident investigations should be acted upon by the EASA, as a matter of urgency in particular when, they relate to defective aircraft design or operational matters. ( EASA,2011)To su ccessfully discharge its responsibilities in this area, the EASA has included in its organ gram an Accident Investigation Section. It is responsible for the follow-up of occurrences where the Safety has been endangered. (EASA,2011)Its main devoted tasks are To follow the progress of aircraft accidents and incidents investigations, To be represented in investigations and collect information related to occurrences, To execute the processing of Safety Recommendations addressed to the Agency, To provide progress notifys and statistics on the Safety Recommendations processing, To maintain a good coordination with European Accident Investigation Bodies, To find safety deficiencies and disseminate related information. 2.2.3 The European trinity (E3)The European Three are combination of the safety bureau in Europe, there are the Air Accidents Investigation Branch ( AAIB) of England, French Air Accident Investigation Bureau ( BEA France) and Aircraft Accident Investigation Bureau (AAIB S witzerland) are recognized as world leaders in several accident investigation areas. non only do they aid nations of the EU in investigations but also non EU nations that have accidents involving aircraft manufactured in Europe, European registered aircraft, accidents occurring in any nation that was a colony of one of the EU member states and any nations requesting help. 2.2.4 Australian Transport Safety Bureau (ATSB)Australian Transport Safety Bureau has gained a reputation as Oceana and Asias air accident investigating body. They are investigators in most of the small island nations of the South and Central peace-loving or whenever requested by other nations. Australias development as a nation through the twentieth century was closely linked to the development of the aviation industry. This industry has helped us overcome vast internal distances and geographic isolation from the rest of the world.(ATSB, 2011)The ATSB is responsible for the independent investigation of accidents and incidents involving civil aircraft in Australia. The ATSBs primary focus for its investigations is fare-paying passenger operations. However, all accidents and incidents related to flight safety in Australia or involving Australian registered aircraft overseas must be account to the ATSB. While the ATSB does not investigate all of these, it still needs to be notified so that the data can be recorded for possible future safety research and analysis. (ATSB,2011)2.2.5 Transportation Safety Board of CanadaThe Canadian Transportation Accident Investigation and Safety Board (TSB) has emerged as the leader in South and Central America. Similar to Australia the small population nation that is firm to ICAO, works in close coordination with the larger NTSB in the USA. However, viewed as an alternate(a) to Washington many Latin American nations work directly with Canada out of desire, security or necessity.(TSB, 2010)Summaries Most nations have the required ICAO investigative agencies but the variations between countries are still very strong. The positive factor for international accident investigation is that many investigators within these nations are willing to call upon each other and aid their work. Working together in the vast majority of air accidents, the public has a good chance of obtaining the trueness about accidents within their borders.2.3 DefinitionBefore going through a little further, these are some definition that being use in the investigation for any accident or incident that happen.

Compressive Sensing: Performance Comparison of Measurement

Compressive Sensing mental branch Comparison of measuringCompressive Sensing A Per constellationance Comparison of Measurement MatricesY. Arjoune, N. Kaabouch, H. El Ghazi, and A. TamtaouiAbstractCompressive spying paradigm involves one-third main regalees fragile re devoteation, amount, and slight convalescence butt on. This theory deals with lean argues using the fact that most of the accredited world orientises ar thin. Thus, it uses a beat hyaloplasm to exemplar sole(prenominal) the components that best represent the thin ratify. The choice of the measuring ground substance affects the victor of the slender recovery process. Hence, the design of an accurate meter ground substance is an outstanding process in compressive sensing. Over the last decades, several bill matrices lay down been proposed. Therefore, a detailed review of these measuring stick matrices and a comparison of their slayings is needed. This report card gives an overview on co mpressive sensing and richlylights the process of step. Then, proposes a three-level bill intercellular substance categorisation and comp atomic summate 18s the per multifariousnessance of eight cadence matrices after presenting the mathematical toughie of from each one hyaloplasm. Several experiments atomic chassis 18 performed to comp ar these standard matrices using four military rank metrics which are distributed recovery error, impact clock time, covariance, and phase rebirth diagram. Results show that Circulant, Toeplitz, and partial(p) Hadamard measurement matrices allow fast reconstruction of tenuous signals with subtile recovery errors.Index Terms Compressive sensing, sparse representation, measurement ground substance, haphazard intercellular substance, deterministic matrix, sparse recovery.TRADITIONAL data acquisition techniques acquire N samples of a presumptuousness signal sampled at a rate at least twice the Nyquist rate in lay to guarantee h one signal reconstruction. After data acquisition, data abridgement is needed to narrow the high amount of samples because most of the signals are sparse and need a few(prenominal)er samples to be represented. This process is time consuming because of the large number of samples acquired. In addition, devices are often not able to store the amount of data generated. Therefore, compressing sensing is necessary to reduce the process time and the number of samples to be stored. This sensing technique overwhelms data acquisition and data compression in one process. It exploits the sparseness of the signal to recover the original sparse signal from a small readiness of measurements 1. A signal is sparse if only a few components of this signal are nonzero. Compressive sensing has be itself as a promising solving for high-density signals and has major applications ranging from image processing 2 to wireless sensor ne dickensrks 3-4, spectrum sensing in cognitive radio 5-8, and s tockpile estimation 9-10.As shown in Fig. 1. compressive sensing involves three main processes sparse representation, measurement, and sparse recovery process. If signals are not sparse, sparse representation projects the signal on a suitable basis so the signal squirt be sparse. Examples of sparse representation techniques are Fast Fourier Transform (FFT), distinguishable Wavelet Transform (DWT), and decided Cosine Transform (DCT) 11. The measurement process consists of selecting a few measurements, from the sparse signal that best represents the signal where. Mathematically, this process consists of multiplying the sparse signal by a measurement matrix. This matrix has to gull a small reciprocal coherence or run into the curtail Isometry Property. The sparse recovery process aims at recovering the sparse signal from the few measurements selected in the measurement process habituated the measurement matrix . Thus, the sparse recovery enigma is an undetermined constitu tion of linear comparabilitys, which has an immortal number of solutions. However, sparsity of the signal and the small mutual coherence of the measurement matrix ensure a unique solution to this problem, which roll in the hay be formulated as a linear optimization problem. Several algorithms commit been proposed to solve this sparse recovery problem. These algorithms can be classified into three main categories Convex and Relaxation household 12-14, Greedy stratum 15-20, and Bayesian category 21-23. Techniques under the Convex and Relaxation category solve the sparse recovery problem through optimization algorithms such(prenominal) as slope Descent and Basis Pursuit. These techniques are complex and have a high recovery time. As an alternative solution to reduce the processing time and speed up the recovery, Greedy techniques have been proposed which build the solution iteratively. Examples of these techniques intromit Orthogonal Matching Pursuit (OMP) and its derivatives. T hese Greedy techniques are faster solely sometimes inefficient. Bayesian found techniques which use a prior friendship of the sparse signal to recover the original sparse signal can be a good approach to solve sparse recovery problem. Examples of these techniques entangle Bayesian via Laplace Prior (BSC-LP), Bayesian via Relevance Vector mould (BSC-RVM), and Bayesian via Belief Propagation (BSC-BP). In general, the existence and the uniqueness of the solution are guaranteed as soon as the measurement matrix use to sample the sparse signal satisfies some criteria. The devil well-known criteria are the Mutual Coherence Property (MIP) and the curtail Isometry Property (RIP) 24. Therefore, the design of measurement matrices is an important process in compressive sensing. It involves devil fundamental steps 1) survival of the fittest of a measurement matrix and 2) determination of the number of measurements necessary to sample the sparse signal without losing the information stor ed in it.A number of measurement matrices have been proposed. These matrices can be classified into twain main categories ergodic and deterministic. hit-or-miss matrices are generated by identical or independent statistical distributions such as Gaussian, Bernoulli, and haphazard Fourier ensembles. These matrices are of two pillowcases un incorporate and organise. Unstructured part matrices are generated haphazardly interest a assumption distribution. Example of these matrices include Gaussian, Bernoulli, and resembling. These matrices are easy to construct and satisfy the RIP with high chance 26 however, because of the ergodicness, they present some drawbacks such as high computation and dear(p) hardware performance 27. Structured type matrices are generated following a accustomed structure. Examples of matrices of this type include the hit-or-miss partial(p) Fourier and the random partial Hadamard. On the other hand, deterministic matrices are constructed determ inistically to have a small mutual coherence or satisfy the RIP. Matrices of this category are of two types semi-deterministic and full-deterministic. Semi-deterministic type matrices have a deterministic construction that involves the randomness in the process of construction. Example of semi-deterministic type matrices are Toeplitz and Circulant matrices 31. Full-deterministic type matrices have a pure deterministic construction. Examples of this type measurement matrices include second-order Reed-Muller codes 28, chant sensing matrices 29, binary Bose-Chaudhuri-Hocquenghem (BCH) codes 30, and quasi-cyclic infrequency parity-check code (QC-LDPC) matrix 32. Several bases that run a performance comparison of deterministic and random matrices have been published. For instance, Monajemi et al. 43 force some semi-deterministic matrices such as Toeplitz and Circulant and show that their phase transition diagrams are similar as those of the random Gaussian matrices. In 11, the autho rs provide a survey on the applications of compressive sensing, highlight the drawbacks of unstructured random measurement matrices, and they present the advantages of some full-deterministic measurement matrices. In 27, the authors provide a survey on full-deterministic matrices (Chirp, second order Reed-Muller matrices, and Binary BCH matrices) and their comparison with unstructured random matrices (Gaussian, Bernoulli, Uniform matrices). All these papers provide comparisons between two types of matrices of the same category or from two types of two different categories. However, to the best of knowledge, no preliminary manoeuver compared the performances of measurement matrices from the two categories and all types random unstructured, random structured, semi-deterministic, and full-deterministic. Thus, this paper addresses this gap of knowledge by providing an in depth overview of the measurement process and comparing the performances of eight measurement matrices, two from ea ch type.The rest of this paper is organized as follows. In Section 2, we give the mathematical puzzle behind compressive sensing. In Section 3, we provide a three-level classification of measurement matrices. Section 4 gives the mathematical model of each of the eight measurement matrices. Section 5 describes the experiment setup, defines the evaluation metrics used for the performance comparison, and discusses the experimental results. In section 6, conclusions and perspectives are given.Compressive sensing exploits the sparsity and compresses a k-sparse signal by multiplying it by a measurement matrix where. The resulting sender is called the measurement vector. If the signal is not sparse, a aboveboard projection of this signal on a suitable basis, can make it sparse i.e. where. The sparse recovery process aims at recovering the sparse signal given the measurement matrix and the vector of measurements. Thus, the sparse recovery problem, which is an undetermined system o f linear equations, can be stated as (1)Where is the, is a sparse signal in the basis , is the measurement matrix, and is the set of measurements.For the next of this paper, we drive that the signals are sparse i.e. and . The problem (1) then can be write as (2)This problem is an NP-hard problem it cannot be solved in practice. Instead, its umbel-like relaxation is considered by replacing the by the . Thus, this sparse recovery problem can be stated as (3)Where is the -norm, is the k-parse signal, the measurement matrix and is the set of measurements. Having the solution of problem (3) is guaranteed as soon as the measurement matrix has a small mutual coherence or satisfies RIP of order. rendering 1 The coherence measures the maximum correlation between any two columns of the measurement matrix . If is a matrix with formulaized column vector , each is of unit length. Then the mutual coherence everlasting (MIC) is defined as(4)Compressive sensing is concerned with matrices that have low coherence, which means that a few samples are required for a perfect recovery of the sparse signal. description 2 A measurement matrix satisfies the Restricted Isometry Property if in that location exist a constant such as(5)Where is the and is called the Restricted Isometry Constant (RIC) of which should be much smaller than 1.As shown in the Fig .2, measurement matrices can be classified into two main categories random and deterministic. Matrices of the offshoot category are generated at random, easy to construct, and satisfy the RIP with a high probability. haphazard matrices are of two types unstructured and structured. Matrices of the unstructured random type are generated at random following a given distribution. For example, Gaussian, Bernoulli, and Uniform are unstructured random type matrices that are generated following Gaussian, Bernoulli, and Uniform distribution, respectively. Matrices of the second type, structured random, their entries are generated following a given mold or specific structure. Then the randomness comes into play by selecting random rows from the generated matrix. Examples of structured random matrices are the stochastic Partial Fourier and the Random Partial Hadamard matrices. Matrices of the second category, deterministic, are highly desirable because they are constructed deterministically to satisfy the RIP or to have a small mutual coherence. deterministic matrices are also of two types semi-deterministic and full-deterministic. The generation of semi-deterministic type matrices are through in two steps the stolonly step consists of the generation of the entries of the first column randomly and the second step generates the entries of the rest of the columns of this matrix based on the first column by applying a simple transformation on it such as shifting the element of the first columns. Examples of these matrices include Circulant and Toeplitz matrices 24. Full-deterministic matrices have a pure deterministic construction. Binary BCH, second-order Reed-Solomon, Chirp sensing, and quasi-cyclic low-density parity-check code (QC-LDPC) matrices are examples of full-deterministic type matrices.Based on the classification provided in the previous section, eight measurement matrices were implemented two from each category with two from each type. The following matrices were implemented Gaussian and Bernoulli measurement matrices from the structured random type, random partial Fourier and Hadamard measurement matrices from the unstructured random type, Toeplitz and Circulant measurement matrices from the semi-deterministic type, and finally Chirp and Binary BCH measurement matrices from the full-deterministic type. In the following, the mathematical model of each of these eight measurement matrices is described.A. Random Measurement MatricesRandom matrices are generated by identical or independent distributions such as normal, Bernoulli, and random Fourier ensembles. These random matrices are of two types unstructured and structured measurement random matrices.1) Unstructured random type matricesUnstructured random type measurement matrices are generated randomly following a given distribution. The generated matrix is of sizing . Then M rows is randomly selected from N. Examples of this type of matrices include Gaussian, Bernoulli, and Uniform. In this work, we selected the Random Gaussian and Random Bernoulli matrix for the implementation. The mathematical model of each of these two measurement matrices is given below.a) Random Gaussian matrixThe entries of a Gaussian matrix are independent and follow a normal distribution with expectation 0 and variance. The probability density function of a normal distribution is(6)Where is the mean or the expectation of the distribution, is the standard deviation, and is the variance.This random Gaussian matrix satisfies the RIP with probability at least given that the sparsity satisfy the following formula(7)W here is the sparsity of the signal, is the number of measurements, and is the length of the sparse signal 36.b) Random Bernoulli matrixA random Bernoulli matrix is a matrix whose entries take the value or with equal probabilities. It, therefore, follows a Bernoulli distribution which has two possible outcomes labeled by n=0 and n=1. The outcome n=1 occurs with the probability p=1/2 and n=0 occurs with the probability q=1-p=1/2. Thus, the probability density function is(8)The Random Bernoulli matrix satisfies the RIP with the same probability as the Random Gaussian matrix 36.2) Structured Random Type matricesThe Gaussian or other unstructured matrices have the disadvantage of being slow thus, large problems are not practicable with Gaussian or Bernoulli matrices. Even the implementation in term of hardware of an unstructured matrix is more catchy and requires significant space memory space. On the other hand, random structured matrices are generated following a given structur e, which reduce the randomness, memory storage, and processing time. Two structured matrices are selected to be implemented in this work Random Partial Fourier and Partial Hadamard matrix. The mathematical model of each of these two measurement matrices is described belowa) Random Partial Fourier matrixThe Discrete Fourier matrix is a matrix whose entry is given by the equation (9)Where.Random Partial Fourier matrix which consists of choosing random M rows of the Discrete Fourier matrix satisfies the RIP with a probability of at least , if (10)Where M is the number of measurements, K is the sparsity, and N is the length of the sparse signal 36.b) Random Partial Hadamard matrixThe Hadamard measurement matrix is a matrix whose entries are 1 and -1. The columns of this matrix are orthogonal. Given a matrix H of order n, H is said to be a Hadamard matrix if the transpose of the matrix H is closely related to its inverse. This can be expressed by(11)Where is the identity matrix, is the transpose of the matrix.The Random Partial Hadamard matrix consists of taking random rows from the Hadamard matrix. This measurement matrix satisfies the RIP with probability at least provided with and as positive constants, K is the sparsity of the signal, N is its length and M is the number of measurements 35.B. Deterministic measurement matricesDeterministic measurement matrices are matrices that are knowing following a deterministic construction to satisfy the RIP or to have a low mutual coherence. Several deterministic measurement matrices have been proposed to solve the problems of the random matrices. These matrices are of two types as mentioned in the previous section semi-deterministic and full-deterministic. In the following, we investigate and present matrices from both types in terms of coherence and RIP.1) Semi-deterministic type matricesTo generate a semi-deterministic type measurement matrix, two steps are required. The first step is randomly generating the f irst columns and the second step is generating the full matrix by applying a simple transformation on the first column such as a rotation to generate each row of the matrix. Examples of matrices of this type are the Circulant and Toeplitz matrices. In the following, the mathematical models of these two measurement matrices are given.a) Circulant matrixFor a given vector, its associated circulant matrix whose entry is given by(11)Where.Thus, Circulant matrix has the following formC=If we choose a random subset of cardinality, then the partial circulant submatrix that consists of the rows indexed by achieves the RIP with high probability given that (12)Where is the length of the sparse signal and its sparsity 34.b) Toeplitz matrixThe Toeplitz matrix, which is associated to a vector whose entry is given by(13)Where. The Toeplitz matrix is a Circulant matrix with a constant diagonal i.e. . Thus, the Toeplitz matrix has the following formT=If we randomly select a subset of card inality , the Restricted Isometry Constant of the Toeplitz matrix restricted to the rows indexed by the set S satisfies with a high probability provided(14)Where is the sparsity of the signal and is its length 34.2) Full-deterministic type matricesFull-deterministic type matrices are matrices that have pure deterministic constructions based on the mutual coherence or on the RIP property. In the following, two examples of deterministic construction of measurements matrices are given which are the Chirp and Binary Bose-Chaudhuri-Hocquenghem (BCH) codes matrices.a) Chirp Sensing MatricesThe Chirp Sensing matrices are matrices their columns are given by the chirp signal. A discrete chirp signal of length has the form (15)The full chirp measurement matrix can be written as(16)Where is an matrix with columns are given by the chirp signals with a fixed and base frequency values that vary from 0 to m-1. To expound this process, let us assume that and Given , The full chirp matrix is as followsIn order to calculate, the matrices and should be calculated. Using the chirp signal, the entries of these matrices are calculated and given as Thus, we get the chirp measurement matrix asGiven that is a -sparse signal with chirp code measurements and is the length of the chirp code. If(17)then is the unique solution to the sparse recovery algorithms. The complexity of the computation of the chirp measurement matrix is. The main limitation of this matrix is the restriction of the number of measurements to 29.b) Binary BCH matricesLet denote as a divisor of for some integer an

Acute Eosinophilic Pneumonia (AEP) Caused by Clomipramine

Acute Eosinophilic Pneumonia (AEP) Ca utilize by ClomipramineClomipramine-induced peachy eosinophilic pneumonia-like syndrome leading to acute respiratory failure a report of kickoff described caseDrugs are well- cognize causes of eosinophilic lung complaint and uncomplainings with drug-induced eosinophilic lung ailment can have variable clinical presentations. Clinical features may range from asymptomatic eosinophilic infilt prizes to acute eosinophilic pneumonia (AEP)-like syndrome leading to acute respiratory failure. This report describes the first case of clomipramine-induced AEP-like syndrome causing acute hypoxemic respiratory failure which was treated successfully. In conclusion, considering the change magnitude use of tricyclic antidepressants, physicians should be aware of this very rare and life-threatening complication of clomipramine.KeyWords Clomipramine, acute eosinophilic pneumonia-like syndrome, treatmentINTRODUCTIONMany drugs have been associated with pn eumonic complications of various types with an increasing number of the therapeutics. Respiratory system is a target for a pastiche of drugs because of its large spot surface and acting as a metabolic process site for drugs. The patterns observed in drug-induced pulmonary toxicity are highly variable and depend on the localization of adverse reaction. Since most of the drug-induced pulmonary toxicities involve the lung parenchyma, the most common form of drug-induced lung toxicity is interstitial lung disease (1).Drugs theoretically can produce all histopathological patterns of interstitial lung disease, including hypersensitivity pneumonitis, organizing pneumonia, bronchiolitis obliterans organizing pneumonia, acute respiratory distress syndrome, granulomatous pneumonitis, and eosinophilic lung disease (2).More than 350 drugs are known to cause acute eosinophilic pneumonia (AEP)-like syndrome (3, 4). However pulmonary complications related to tricyclic antidepressants are uncommo n. To our knowledge, only one case of AEP associated with the usage of clomipramine has been reported in PubMed in 1999, and in the aforementioned case clomipramine had been used not totally but with sertraline (5).This report describes the first and successfully treated horrific case of AEP-like syndrome associated with clomipramine treatment alone. Written informed consent of the participant persevering was obtained for the publication of this case report and any accompanying images.CASE invoiceA 38-year-old female was referred to our clinic from psychiatry department of an early(a) hospital. She had been newly diagnosed with panic attack attack and anxiety disorder one week prior to the fashion of respiratory symptoms. After admission to psychiatry polyclinic, clomipramine therapy was prescribed at a dose of 75 mg/day. After 6 days of clomipramine therapy, the patient exhibited dyspnea, increasing shortness of breath, dry cough, chest pain, and fever up to 39.20C. She was a housewife and had no work-life memorial. there was no past history of a chronic disease and her smoking history was 16 packs/year. She had never consumed adulterous drugs, had no allergies, and had not visited a foreign country during the previous 5 years.On admission, the patient was in a respiratory distress, with a respiratory rate of 35 breaths/ s, a blood pressure of 110/70 mmHg, and a heart rate of about 140 beats/minute with sinus tachycardia. Examination of blood samples revealed only anemia (haemoglobin9.4 g/dl). calculate of leukocytes, thrombocytes, and results of blood chemistry were inwardly normal limits. Erythrocyte sedimentation rate was 40 mm/h and serum level of C-reactive protein was 4.5 mg/dl. step of arterial blood gas analysis on room form revealed pH 7.44, PaCO2 32 mmHg, PaO2 49 mmHg, HCO3 27 mmol/L and SaO2 86% which was harmonious with hypoxemic respiratory failure. Laboratory results including HIV testing, serological screening for vasculitis auto antibodies to deoxyribonucleic acid (DNA), mental image stranded DNA, proteinase-3, myeloperoxidase, rheumatoid factor, and circulating immune complexes and various pulmonary pathogens were negative. pee-pee tests for ova and pulmonary parasites were normal. The level of total serum immunoglobulin E (Ig E) was within normal limits (65 IU/ml) and antigen-spesific Ig E against Aspergillus fumigatus and Candida was negative.Her chest radiograph revealed a homogenous dense shadow located especially in the trim down field of the right lung and some additional reticular opasities in the reject zone of the left lung (Figure 1). Computerized Tomography (CT) (Brilliance Philips Medical System, Eindhoven, The Netherlands) of the thorax demonstrated patchy areas of ground-glass, thickened interlobular septae and homogenous consolidations with air-bronchograms especially in the middle and light zones of the right lung (Figure 2).The patient was admitted to the intensive care unit because o f the need for non-invasive robotic ventilation. She underwent bronchoscopy (Aquilion Toshiba, Tokyo, Japan) with bronchoalveolar lavage (BAL). During the bronchoscopy procedure the bronchi appeared inflamed and contained increased secretions. Gram stain and cultures of the bronchial washings did not reveal any infectious organism. Total cell count on BAL was 182 cells/mL with 30% eosinophils, 8% neutrophils, 55% macrophages, and 7% lymphocytes. Special stains and cultures for mycobacteria, Pneumocystis jiroveci, fungi, legionella pneumophila were negative. Serology testing for cold agglutinins were negative.Intravenous methylprednisolone 60 mg/day (1 mg/kg/day) was initiated on admission. Then dose of the methylprednisolone was gradually tapered and methylprednisolone was discontinue after 4 weeks. The chest radiograph of the patient cleared markedly within 15 days of the treatment (Figure 3). The patient was decampd 18 days after admission. Follow-up examinations one and four we eks after boot out revealed normal laboratory results and a normal chest radiograph. Pulmonary knead tests 3 months after admission showed no ventilatory defect. Last contact with her was a polyclinic visit for control one year after discharge and she was free of respiratory symptoms.DISCUSSIONThe eosinophilic lung diseases are a assorted group of pulmonary disorders characterized by increased numbers of eosinophils in the air hose or lung parenchyma, and drugs are well known causes of eosinophilic lung disease (6). Patients with drug-induced eosinophilic lung disease can have variable presentations, ranging from asymptomatic transient eosinophilic infiltrates to AEP-like syndrome leading to acute respiratory failure, depending on the drug involved.AEP is described as a clinical entity which involves acute onset of symptoms within 5-7 days, fever 37.20C, hypoxemia, two-sided alveolar or mixed alveolar and interstitial infiltrates, and lung eosinophilia (percentage of eosinophil s 25% in BAL and/or predominance of eosinophils in open lung biopsy). In addition, without any history of hypersensitivity to drugs, no evidence of infection, and no other known cause of eosinophilic lung disease (7, 8).Similarly, patient in this case had newly onset respiratory symptoms, fever and mixed alveolar and interstitial infiltrates suggesting an interstitial lung disease. In addition, a bronchoscopy with BAL revealed presence of importantly increased percentage of eosinophils (30%) in the lavage fluid. Based on the results of BAL, radiological features and her clinical course, she was diagnosed as potentially having an AEP-like syndrome related to clomipramine.Unlike patients with other eosinophilic lung diseases, most of the patients with AEP have normal peripheral blood eosinophil count (8). The level of total serum IgE can be elevated, however it is not used as a diagnostic legal document (9). In this case, the patient had both normal peripheral blood eosinophil count and normal level of total serum Ig E.The diagnosis can easily be obtained with BAL and lung biopsy is not an obligation for the diagnosis of AEP in most cases. If needed, the purpose of lung biopsy is to exclude other diseases that can mimic AEP. When lung biopsy is performed, the histopathological features are characterized by diffuse alveolar damage with interstitial and alveolar eosinophils (10). There was no need for lung biopsy in this case and diagnosis could be formal with the help of BAL cell count.In some cases discontinuation of the drug is generous for resolution of the radiological features. However, some patients experience a severe disease and require corticosteroid treatment. Generally, response to corticosteroids is rapid and most of the patients have evidentiary clinical improvement within 24 to 48 hours. The optimal dose and duration of corticosteroids have not been determined exactly (8, 10). Commonly used doses of intravenous methylprednisolone in case series range from 60 to grand piano mg per day until respiratory failure resolves. Thereafter, the patient can be switched to oral prednisone, and the steroids can be tapered off over 2 to 12 weeks. In this case, 60 mg/day intravenous methylprednisolone was administered on admission and dose of the corticosteroid was regulated according to resolution of radiological findings.
