Application of LBM in Aerospace Industry
Application of LBM in Aerospace Industry INTRODUCTION: Requirement of precision components, complicated design, stringent standards and testing, unusual size of workpiece, restrictions in conventional machining processes has lead to development of advanced machining processes shortly AMP. In past few years, there were several AMPs developed such as electric discharge machining (EDM), electron beam machining, electrochemical machining, chemical machining processes (CMP), ultrasonic machining (USM), and jet machining processes abrasive jet machining, water jet machining, laser beam machining etc. Each of these AMPs has its limitations in workpiece material, shape etc. But LBM is the one of the AMPs where almost all material can be processed. One of major advantage of LBM is its ability to machine both conductive and non-conductive materials. Laser beam machining (LBM) is one of the most widely used thermal energy based non-contact type advance machining process which can be applied for almost whole range of materials. Laser beam is focused for melting and vaporizing the unwanted material from the parent material. As of now the major application on LBM is profile cutting of geometrically complex part and making miniature holes in sheetmetal. HISTORY OF LASER: In 1917, it was Albert Einstein who first told the world about the process called Stimulated Emission which makes the laser possible. In 1957, Gordon Gould, a Columbia University student designed the first laser device in his laboratory. However the first working laser (ruby laser) was found on 16th of May, 1960 by Dr. Theodore Maiman. This demonstration of ruby laser acted as entry door to this field. Till then lots and lots of researches have been done and various lasers were found. Some of major contributions and highlights are Gas laser which used helium and neon gases by Ali Javan during 1960, semi conductor laser by Gunther Fenner in 1962, CO2 laser by Kumar Patel on 1964, Nd-YAG laser by Geusic in 1964 etc. The first excimer laser was demonstrated in 1970 by Basov et ah and it was liquid xenon which was excited with a pulsed electron beam. The first commercial application of continuous wave CO2 lasers was made during 1967 by Western Electric and the first successful industrial application of laser cutting was die-board slotting. Whereas now, lasers have been into many areas such as aerospace, die and mold manufacturing, biomechanical devices, automotive, electric, and electronic industries etc. Likewise many studies have been made to find many such lasers and also studies were done to improve / optimize the working parameters of the lasers. FUNDAMENTALS OF LASER: Light Amplification by Stimulated Emission of Radiation LASER is a device which produces a monochromatic light beam where all the waves are coherent. LASER consists of four primary components: Active medium: It contains atoms whose electrons are excited to higher energy levels by an energy source. They are solid crystals such as ruby or Nd:YAG, liquid dyes, gases like CO2 or Helium/Neon, or semiconductors such as GaAs. Excitation Mechanism: Excitation mechanisms pump energy into the active medium. Three basic method of excitation are optical, electrical or chemical. High Reflectance Mirror Partially Transmissive Mirror The major principles of Laser are stimulation, amplification and population inversion. Lasing action: When energy is applied to a laser active medium electrons are raised to an unstable energy level then spontaneously decay to a lower relatively long-lived metastable state. There is possibility to pump large amounts of energy since electrons in this state will not spontaneously return to their ground energy level; thus we can obtain a population inversion in which most of the atoms are in a metastable state. Lasing action is initiated by an electron after achieving population inversion. If the photon released is of exactly the right wavelength it will stimulate an atom in a metastable state to emit a photon of the same wavelength (Stimulated Emission). Large amount of these stimulated photons will be lost when they interfere with the sides of the lasing active medium. However if the photons travel parallel to the long axis of the optical cavity they will continue to stimulate emissions of photons having the same wavelengths which combine coherently until they reach the mirrored ends of the optical cavity. This stimulated emission continues as the beam strikes the 100% reflective mirror and gets reversed to strike against the partially reflecting mirror. A small portion of the coherent light is released while the rest is reflected back through the lasing medium to continue the process of stimulating photons. Types of Laser: There are several types of lasers available based on active medium (solid, liquid or gas), types of gases used, types of crystals used, and mode of operation (continuous wave, pulsed, q-switched) etc. But only few lasers are used for industrial application called as material processing lasers. The commonly used lasers in industries are: CO2 Gas lasers; Nd-YAG solid state laser and Excimer laser. CO2 lasers tend to be high powered (up to 3 kW) and are used in the continuous-wave mode. The Nd-YAG lasers are used in the pulsed mode and can achieve peak powers of 7-10 kW. Mechanics of Laser: The mechanism of material removal during laser beam machining includes four different stages such as: Warm up Melting, Vaporization, Chemical degradation / plasma shielding The material is heated above its melting point when a high energy laser beam is focused on workpiece surface. The melted or vaporized material is then removed by using high pressure assist gas. Unlike other processes, LBM is a thermal process and the effectiveness depends on thermal properties of the material rather than its mechanical properties. This is the major characteristics for which hard-to-machine material such as titanium alloys, super nickel alloys etc and highly brittle material such as glass, ceramics etc can be processed by LBM. NEEDS OF LASER IN AEROSPCE INSUSTRY: As mentioned earlier, lasers are employed much more in material processing industries than other industries. And current scenario of material processing, application of lasers plays a vital role in aerospace industry. The following are some of key points which explain the reason behind this: Cooling holes: Aerospace engineering technology is growing rapidly and the components are exposed to ever increasing exhaust and combustion temperatures. Hence cooling is very much required in order to withstand those high temperatures. One of method is to have cooling holes on TBC (thermal barrier coated) layers. Modern aircraft has nearly 100,000 such cooling holes which are made by laser drilling operation. Airframe weight: One of major criteria of any aircraft is the weight. Many improvements and experiments are going on to lessen the weight of airframe structure. Also it enhances low fuel consumption. High strength aluminum alloys are used for this process. It is found that almost 80% of material used in commercial aircraft and 50% material used in military aircraft is of this aluminum alloy. Laser cutting is one of highly recommended for processing this material. Reduce cost: In this present scenario, cost reduction plays an important role in any industry. With increasing price of petroleum, one of strategy is to reduce total manufacturing cost, labor cost in particular. CNC controlled motorized laser can be used for drilling and cutting purposes which reduces the manufacturing cost. MAJOR LBM PROCESSES USED IN AEROSPACE INDUSTRY: There are two major LBM processes employed in aerospace industry namely, laser drilling and laser cutting. In this report I have made some investigation on two case studies, one for laser drilling and another for laser cutting. Laser Drilling: In laser drilling process is a thermal process which incorporates high energy laser beam which is focused on particular area where the material gets vaporized to form holes on workpiece. There are two types of laser drilling process, percussion laser drilling and trepan laser drilling. Percussion laser drilling: Percussion drilling is drilling where it directly punches the workpiece material where there is no relative movement of laser or workpiece. Thus the processing time is much less when compared to trepan drilling process. Also for drilling 100,000 holes in aircraft components such as turbine blades, airfoil vanes etc, percussion drilling is recommended. Trepan drilling: This drilling involves cutting around circumference of the hole. Thus it takes more time than percussion drilling since it has to go around the circumference to make a hole on workpiece material. Laser cutting: Laser cutting process involves basic principle of mechanics of laser i.e. high energy laser beam is focused to particular area on the workpiece where the material is melted above its melting point. Then the molten material is removed by coaxial assist gas jet or induced vapor pressure thus forming the cut kerf. There are three types of laser cutting processes, laser fusion cutting, laser flame cutting and sublimation cutting. Laser fusion cutting: In this process inert gas such as nitrogen, argon etc is used as assist gas. This process fully depends on the energy of laser beam which is used for high alloyed steels. Laser flame cutting: Oxygen is used as assist gas in this process and it is widely used for low alloyed steels. This process receives some amount of energy from exothermic reaction of the workpiece material. Also the laser power is lower when compared to laser fusion cutting. Sublimation cutting: The material is molten by absorbed laser energy until it partially evaporates. This requires high power densities with much slower speeds than other to cutting processes. CASE STUDY # 1: LASER DRILLING OF MULTILAYER AEROSPACE MATERIAL Objective: As mentioned earlier, aerospace components requires thousands of cooling holes to dissipate the heat of combustion and exhaust gas. These components are given a coating called TBC thermal barrier coating to protect the components from direct exposure to the corrosive environments. Thus the objective of this case study is to investigate and optimize the optimum parameters related to quality of drilled holes on a TBC, thermal barrier coated material. Some of such parameters are mentioned in below figure. Experimental Setup: Laser system: The experiments are made using Nd-YAG JK704 laser with lens of focal length: 120mm. Oxygen is used as assist gas. Previous studies by Corcoran et al identified oxygen as the suitable assist gas for this process. The below chart shows the specification for JK704 laser system. Workpiece setup: Experiments are carried out using Rene 80 substrate coated with TBC. Here yttria stabilized zirconia is used as TBC and it is bonded with the substrate material by means of plasma sprayed MCrAlY bind coat. The material thickness is about 3.6mm. The material composition of Rene 80 is: Ni= 60.0%, Cr= 14.0%, Co= 9.5%, Ti= 5.0%, Mo= 4.0%, W= 4.0%, Al= 3.0%, C= 0.17%, B= 0.015% and Zr= 0.03% Procedure: One-at-a time approach is the traditional approach for conducting laser drilled experiments. In this approach only one parameter is changed keeping all others as constant. But this is time consuming and most importantly interactions of parameters are not considered which may lead to wrong results. Thus Taguchi type approach is considered where orthogonal array was designed to reduce the number of experiments required. From 108, the experiments are reduced to 18. Holes were drilled on Rene 80 substrate surface by percussion laser drilling using the laser system as mentioned earlier. The mean diameters were recorded using profilometer. The following output responses were recorded: Remelt layer thickness; Microcracking depth and Spalling Delamination of TBC. Results: After recording the values as mentioned in the experimental procedure, a chart was plotted which gives the direct comparison of results of 18 experiments. The Taguchi analysis gives the output responses of Remelt layer thickness and microcracking depth which can be then compared with the OEM (Original equipment manufacturer) vane airfoil standards. This is to check whether the attained values are within the mentioned values mentioned in the standards. As per OEM standards, the remelt layer thickness Higher S/N ratio is preferred in S/N analysis. By using the results from Chart 4 i.e. parameter effects plot, the optimum parameters can be obtained for laser drilling of Rene 80 sample. These optimum parameters are chosen in such a way that the remelt layer thickness, microcracking and Delamination of TBC are minimized. Based on derived optimum parameter table, microcracking confirmation tests are carried out to validate the findings. It was found that the laser drilled holes posses very little microcracking at these optimum parameters (Table 3). Three iterations were made, say A, B and C and micrographs were obtained. Conclusion of case study #1: The parameters considered for this study are pulse energy, pulse width, pulse shape, TBC density and the gas pressure. The investigation and results of above case study provides the following conclusions: Pulse energy: High pulse energy reduces the level of microcracking and low pulse energy reduces the level of melting of remelt layer thickness. It is also found that interaction occurs between pulse energy and pulse width. Pulse width: The severity of microcracking and Delamination i.e. the spalling is reduced considerably when shorter pulses are used. Pulse shape: Pulse shape do not have adherent effect on remelt layer thickness whereas in order to minimize delamination, a ramp-up pulse is recommended and to minimize microcracking, a treble pulse is recommended. TBC density: The TBC density has very little effect on the remelt layer thickness, however high density TBC yielded least delamination of bond coat and the TBC used. Gas pressure: Higher the gas pressure is better the output parameters. Gas pressure of 70 psi was found to reduce all the three output response parameters remelt layer thickness, microcracking and delamination. Some pictures showing the laser drilled holes on aircraft turbine component. CASE STUDY #2: LASER CUTTING OF AEROSPACE ALUMINIUM: One of primary goal of aerospace industry is to lessen the weight of airframe structure. This has advantage of saving fuel consumption, and hence the cost. High strength aluminum alloys were used for these applications and laser cutting is one of process which is recommended for processing high strength aluminum but there are some challenges which has limited conventional laser cutting for this application. Objective: Thus, the objective of this case study is to investigate the challenges of conventional laser cutting and study the proposed solution to overcome these challenges. Conventional laser cutting: The usage of conventional laser cutting is limited to process aluminum alloys used in aerospace application is because of two major reasons, It produces cuts with poor surface finish and Large heat affected zone (HAZ) is created. These poor machining characteristics of laser cutting decrease the fatigue life of components which is very essential for aerospace applications. The mechanisms of laser cutting process is, when a high energy laser beam is focused on the workpiece the material gets melted and vaporized and then a assist gas jet is used to drag the molten material away from the workpiece material. If these dragging requirements are not more pronounced, then the molten material may remain in the cutting edge of the workpiece which yields to very poor quality cut and also large HAZ is generated in the cut edge. These all combine to affect the overall mechanical performance of the workpiece material. The best method to improve the dragging efficiency is to increase the gas pressure of assist gas jet. This is required in order to establish a laminar boundary layer between assist gas jet and the molten material. The dragging of molten material is more efficient as a result viscous and pressure drag of the assist gas jet which are the driving force of removal of molten material from the workpiece. Gas pressure cannot be increased beyond 2 bar in conventional laser cutting as it uses converging coaxial cutting head. Any pressure more than 2 bar yields to more aerodynamic interactions. Due to this MSD mach shock disk, a normal shock wave is created which produces serious degradation in gas jet and reduces the dragging capacity. Proposed laser cutting: The drawbacks of conventional laser cutting can be addressed by using Converging diverging (supersonic) nozzle instead of coaxial nozzle Different geometrical configuration of assist gas jet such that it is in off-axis with the laser beam. Using converging- diverging nozzle, we can produce a fully expanded free-jet where MSD can be avoided. Thus we can produce cut of superior finish and also the HAZ is significantly reduced. Experimental setup: The experimental setup used for proposed laser cutting is as follows: Laser used: CO2 slab laser (Rofin DC 035) Output power: 3.5 KW Mode of operation: CW, continuous wave mode Nozzle: Self designed cutting head (supersonic head) Experiments were conducted using conventional and supersonic cutting head and results were recorded. Comparison of results: The workpiece material used fro this experiment is 2024-T3, high strength aluminum alloy. The results were recorded and compared to conventional laser cutting. It was found that the finish was superior and HAZ was reduced than conventional laser cutting. A Challenge in proposed solution: One of major drawback in proposed solution is that, for cutting complex contours the supersonic cutting head has to be changed frequently to remain tangent to the cutting direction. This drawback can be overcome by using a motorized off-axis nozzle controlled by a CNC controller. Conclusion of case study# 2: The following are the conclusion derived from above case study is that by using a cutting head supersonic, off-axis (non coaxial) nozzle can process high strength aluminum alloys with An excellent and superior finish. Negligible heat affected zone, HAZ can be obtained. Production rates can be increased since cutting speed is increased. By using a CNC controlled motorized off-axis cutting head, parts with complex contours can be processed. Labor costs can be reduced as laser is fully automated. CONCLUSION: In this report, a brief discussion about the two major laser beam machining used in aerospace industry, laser drilling and laser cutting were discussed. Also two case studies related to respective process were studied and results were mentioned. LBM is widely used in aerospace applications and more and more researches are going on to improve the current laser technology and many new trends directions were forecasted in this aerospace engineering field.

Essay --
Introduction: Vietnam is a small country located in Southeast Asia with a S-curve shape. Vietnam has three sections including North, Central part and South. Hanoi, in the North part, is the capital of Vietnam but it is not the largest city as people thought. Otherwise, Ho Chi Minh City, in the South part, is not only the largest but also the most population city, the center of economy, culture, and education, which plays the important role in the development of Vietnam. Therefore, getting knows more about Vietnam is an interesting issue including historical evolution, special features, problems and some recommendations about urban studies. Body: Historical evolution: This area was originally known as Prey Nokor, a part of the Kingdom of Cambodia, which served as an important fishing village and harbor of Khmerââ¬â¢s people. After that it was annexed by Vietnamese, and then city was formed thanks to the exploration of the Nguyen Dynasty. When the French was in Indochina, Saigon quickly grew up to become one of the most important cities in Vietnam. At that time, Saigon was considered as the capital of the Indochinese Union in the 1887-1901 period. In 1954, Saigon was named the capital of the Republic of Vietnam. It was one of the most important cities of Southeast Asia. In 1976, National Assembly of Vietnam decided to change the name Saigon into "Ho Chi Minh City", after the first President of the Democratic Republic of Vietnam. Special features of the city: The cityââ¬â¢s creative dynamism is the attraction, and motivation to develop the industrialization and modernization today. After 25 years of renovation, the city has made great achievements, fundamental changes in its social life, and many important contributions to the country in... .... Overpopulation: In my opinion, HCM city should issue regulation to "tighten" immigration, which include requirements such as: immigrants must prove that he/she has been living in the city more than 3 years, with an area of housing per capita is 15 mà ² etc. Moreover, while residents in the city have the right to own property and access to schools and health services for a reasonable fee. Conversely, illegal immigrants are not entitled to. In some case, they have to pay double the cost of electricity and water, or triple for tuition fee. Conclusion: Despite the fact that the city has to face so many problems and challenges, Ho Chi Minh City still developes and innovates day by day. In fact, these difficulties are obviously to all cities while expanded period. Recognizing the problems and finding proper solutions, the city will develop in a better comprehensive way.
Contemporary History in Anilââ¬â¢s Ghost Essay -- Literary Analysis
There is always a problem of historical inaccuracies in fiction. When certain historical events become a part of the narrative (especially when these events are controversial), it is important to understand what they mean in the authorââ¬â¢s conception of history and reality in general. Far more important is to understand their place in this conception when we see that the authorââ¬â¢s depiction of facts is unusual and what he does seems to be not the reflection of existing reality but the deconstruction of a different one. Terrorism, civil war, separatism ââ¬â it is hard to remember the themes that would be more complicated and controversial in the modern world, because questions like these never have a certain answer. Michael Ondaatjeââ¬â¢s Anilââ¬â¢s Ghost is a good example of a novel that deals with the most important problems of contemporary history. Anilââ¬â¢s Ghost, first published in 2000, and is dedicated to events of Sri Lankan Civil War. Michael Ondaatje claimed in interviews that his book is not ââ¬Å"just about Sri Lanka; it could be Guatemala or Bosnia or Irelandâ⬠(Scanlan 302) ââ¬â so it can be suggested that the author is trying to describe not this particular conflict, but the situation in general. In another interview Ondaatje says: ââ¬Å"Anil's Ghost is a more faithful or more nonfictive version. It's a fiction. It is a novel, and it is also a point of viewâ⬠(Coughlan). Sri Lanka is mentioned as one of the places in which the war ââ¬Å"always seems to be there, and nobody goes to it anymoreâ⬠(Champeon). The conflict that still takes place is set between the government and Liberation Tigers of Tamil Eelam, a separatist group. Different issues state that at the moment the number of victims is about 80.000 people. The action takes place at the end o... ...every country with the similar circumstances and not only in Sri Lanka. The experience of civil war is reconstructed in destinies of main characters ââ¬â everyone of them has his personal tragedy and deals with it the way he can. And when neither the executioner nor the victim can be identified, it becomes important to give the identity to at least one of the murdered. It has to be named, and the problem has to be named, too. Through the historical situation the author tries to show us the necessity of personal choice in the times when there is no choice for the nation or the whole country. Anilââ¬â¢s ghost is many different ghosts ââ¬â ghost of innocent people, who disappeared or died, ghost of the past, which has to be dealt with; ghost of Sarath, who finally becomes a martyr. And these ghosts donââ¬â¢t seem to be Anilââ¬â¢s only. In some reasons they belong to each other.

Dimmesdales versus Danforths Sins in Hawthornes Scarlet Letter :: essays research papers
In the words of Alexander Pope 'To err is human.' Everybody makes mistakes. It is human nature. However, how one deals with the mistake is much more important than the mistake itself. In Nathaniel Hawthorne's The Scarlet Letter and Arthur Miller's The Crucible, Dimmesdale and Danforth's sins have similar motives, but the characters have distinctly different methods of sin and resolution. Dimmesdale is a selfish coward. He does not work toward anything substantial. Although he supposedly loves Hester, he refuses to admit that he was her ?fellow-sinner and fellow-sufferer? ( Hawthorne, 65). When Pearl asks Dimmesdale to accompany her and her mother when they stand at the scaffold, he refuses for fear of public exposure. He has put Pearl and her mother through a lot, but will not stand along side them during their public shame, even though he is the cause of it. Danforth, like Dimmesdale, is cowardly and selfish. He thinks solely of himself and his position of power as he sends dozens of people to the gallows. He refuses to let the accused have fair trials, denying their requests for legal representation and having a jury of corrupt young girls in charge of sentencing. He does everything he can to keep himself from losing credibility. Both Dimmesdale and Danforth put their careers first. Dimmesdale proves this constantly throughout the book by considering his own career and distinction a higher priority than Hester, the woman who loves him, and his child, who must grow up, corrupt in the eyes of society, like her mother. Danforth cherishes his position above all else. When Parris, fearing for his well-being, asks Danforth to postpone further sentencing, he replies ?There will be no postponement? (Miller 128). He does not want the townspeople to think he is wavering and fears they will begin to doubt the so-called ?good? of what he is doing for the town and its God-fearing citizens. Danforth and Dimmesdale contrast in the way of their sins of commission and omission. Although Dimmesdale does not openly admit his sins until the end of the story, they feed on his conscience, causing him to engage in self-torturing practices. He confuses the destruction and weakening of himself for penance for his sin. Aided by Hester?s angered husband, Dimmesdale weakens himself so much, that he uses the last of his strength in his confession and he dies in Hester?s arms. Danforth suspects he is sending innocent people to their deaths, but through the love of his office, he does not stop his corrupt practices nor attempt to right his wrongs.

American Fast Food in Korea Essay
1. Base on market information for Asia Pacific, we can made conclusion that business future in Asian region has to have bright future. With 33% of the worldââ¬â¢s GDP and 50% of its population, Asia has emerged as a rapidly growing force in the global economy. Due to the cultural diversity, regulatory controls, growing base of consumer power and its own set of business ââ¬Å"rules,â⬠the multinational corporations (MNCs) find it challenging to enter the Asian market successfully. Most MNCs are reassessing their existing strategies or formulating new strategies to sustain their growth (4). With regional exports exceeding $1. 3 trillion, the East Asia and Pacific regionââ¬â¢s share of trade in GDP is the highest in the world. (Global Development. Finance Report. 2006). The economy of South Korea has grown in the last 35 years. Per capita GNP only $100 in 1963, exceeded $20,000 USD in 2005. South Korea is now one of the worldââ¬â¢s largest economies (as of 2006, it is 14th in the world according to GDP). (2). If we will compare Korean market to East Asian countries (Exhibit 1 p. 12). From report I have strong understanding that mane fast-food market in any Asian countries is in big cities. Letââ¬â¢s check urban population level in all Asian countries. Based on Exhibit 1 we can clearly see that Korea has one of the best Urban Population level-total population level 47. 6 million and urban population is 82%. Check GDP and GNI level. We can see that Korean level one of the highest in the Asia. Nominal GDP (2005 est. ): $811. 1 billion. GDP growth rate: 2003, 3. 1%; 2004, 4. 6%; 2005, 4. 0%. Per capita GNI (2004): $14, 162. (5). In 1997 Korea had some serious economic crises and faced sever difficulties. After some structural reforms in Korean government, economy starts to recovery. Already In 2001 Korea was 13th largest economy in the world with GNP of $398 billion. So based on all information from above I can make conclusion that Korea has good future and it is one of the most promising market in Asian region. 2. Porterââ¬â¢s Five Forces have become a yardstick for assessing industry profitability. They areâ⬠¦ ?Buyersââ¬â¢/customersââ¬â¢ power ?Suppliersââ¬â¢ power ?Rivalry among competitors ?Threat of new entrants ?Threat of substitute products I will try to analyze each one, for Korean fast food market. Buyers ââ¬Ëpower. The power of buyers is the impact that customers have on fast food industry. Buyers could be powerful in different circumstances. I believe that in our case we can say that buyers are concentrated. As I could explain earlier, main per cent of population in Korea are in the big cities. Its give us good idea that for fast food industry in this region will be easier to delivery product to the customers. Buyers purchase the significant proportion of output. Suppliers power. A fast food industry require raw material for there business-labor, components. It leads to buyer-supplier relationship between the fast food industry and the firms that provide it the raw materials used to create products. Suppliers are powerful if they are concentrated- it will be really expensive to switch the supplier. From another side suppliers are week if it will be many suppliers with standard product on the market Korean agriculture sector includes forestry and fisheries. National products are rice, vegetables, fruit, root crops, barley; cattle, pigs, chickens, milk, eggs, fish. About 20% of the land used for agricultural busyness (5). From here we can understand that for fast food companies will be easy to find or switch the suppliers without problems for there businesses. Threat of new entrants. The possibility that new firms may enter the industry also affects competition. In theory any firm should be able to enter and exit market. And if free entrance and exit exists, than profit always should be nominal. There are some barriers of entry. Easy to entry if: little brand franchise; access to distribution channels; common technology. On Korean market steal not allot firms with brand franchise. And it is big requirement in new choices for customers. It let us know that it will be easy to enter to the market. Threat of substitute products. Product price elasticity is affected by substitute products-as more substitute become available, the demand becomes more elastic since customers have more alternatives. A close substitute product constrains the ability of firms in an industry to raise prices. In our case we can see example of some firms, Lotteria and McDonalds, who easy change there recipes for Korean customers which needs more healthy national ingredients for there food. Rivalry among competitors. In pursuing an advantage over its rivals, a firm can choose from several competitive moves: changing prices; improving product; creatively using channels of distribution; exploiting relationship with supplier. For firm who will try to enter Korean market, I would say more realistic and more helpful move will be to improve products. Improving quality of materials, quality of services, and probably quality of food preparation technology (healthier environment), will be most important key to success on the Korean fest food market. 3. Urban Koreans eat out frequently. Fast paced lifestyles are driving Koreans to choose western-style fast-food, but healthy eating is a concern. These factors are driving a fast growing market for sandwich store franchising (3). Another important factor is that about 75%-80% fast food customers are young people whose age less than 20 year old. It is mean that ââ¬Å"along with westernization of Korean taste, western chain gained in popularityâ⬠. In the past, people seeking a fast meal would have been satisfied by fast-food giants like McDonaldââ¬â¢s or Burger King, but it is changing. Consumers are seeking different choices. This new requirements has opened doors for a steadily growing market for fresh and healthy sandwich businesses. Lotteria is a local hamburger franchiser and is the fast-food market leader in Korea. From 2002 to 2003 Lotteria experienced a sharp sales drop of 40%. However, a strong contrast was seen in the South Korean sandwich market, as its $41. 20 million1 market value in the second quarter of 2003 doubled to $82. 40 million in the fourth quarter. This dramatic growth is forecast to continue, and the anticipated market value for 2004 is $117. 71 million (3) Besides Lotteria, the local franchisers include Sandday, Sandpresso and Sand & Food. In response to the aggressive foreign companies, they are also coming up with strategies to secure their position within the market, and the competition is about to heat up. Based on all this information I would say that fast food business in Korea growing and this will continue until people need more choices. 4Globalization is the key to sustained growth for Yum Company! Brands, the worldââ¬â¢s biggest quick-service restaurant company headquartered in the United States and managing five fast food brands ââ¬â KFC, Pizza Hut, Taco Bell, A&W and Long John Silverââ¬â¢s. ââ¬Å"Demand for fast food is rising because lifestyles are changing,ââ¬â¢Ã¢â¬â¢ said Allan, who leads overseas operations outside of the U. S.and China, in a recent interview with The Korea Times. More Koreans are being time pressured than they were historically. This trend is happening here. The number of people eating ready made food is continuing to increase. ââ¬â¢Ã¢â¬â¢(Graham Allan, president of Yum! Restaurants International. 11. 06. 2006) (6). As a socially responsible company, the 51-year-old executive said Yum will provide more optional dishes to health-conscious consumers amid a well-being spree in the nation, but will not abandon its traditional concept of ââ¬Å"great taste. ââ¬â¢Ã¢â¬â¢ Under his leadership, Allan said he will target an annual growth of 10 percent or more in operating profits. There are about 250 Pizza Hut delivery outlets in the nation, which are set to expand to over 400. Korea makes up about 5 percent of Yumââ¬â¢s international division sales, which amount to some $11 billion ââ¬â half of the groupââ¬â¢s overall system sales. If I were business consultant, I would recommend starting making money on Korean fast food market. The new trend is propelling growth in the franchising market. It is anticipated that the market will experience intense competition for the next couple years. New fast food companies should be able to take advantage of the situation and enter the market without much difficulty, while it is still at an early stage of development.

New Revelations of Pre-Columbian America
In his breakthrough book, 1491: New Revelations of the Americas Before Columbus, Charles C. Mann changes myths about the Pre-Columbian America into scientific facts that nobody would deny.à The book is a discussion about the scientific reality of Native American life before Columbus set foot in America.à As it turns out, this view of reality based on scientific details is completely different from what we had previously thought about Pre-Columbian America.à The thesis of Mannââ¬â¢s book may be summed up in his own words thus:When I went to high school, in the 1970s, I was taught that Indians came to the Americasà across the Bering Strait about thirteen thousand years ago, that they lived for the most part inà small, isolated groups, and that they had so little impact on their environment that even afterà millennia of habitation the continents remained mostly wilderness.à Schools still impart theà same ideas today.à One way to summarize the views of people li ke Erickson and Balà ©e wouldà be to say that they regard this picture of Indian life as wrong in almost every aspect.à Indiansà were here far longer than previously thought, these researchers believe, and in much greaterà numbers.à And they were so successful at imposing their will on the landscape that in 1492 à Columbus set foot in a hemisphere thoroughly marked by humankind.After introducing the main thesis of his book ââ¬â that, in fact, Native Americans were far more civilized than we had previously imagined ââ¬â Mann begins ââ¬Å"Part One: Numbers from Nowhereâ⬠by dealing with New England in the 1600s, and the myth that European technology was far superior to American Indian technologies.à This myth was based on the fact that the Indians did not appreciate guns.à However, the reality is that the Indian moccasins were far more comfortable than the boots of the European; and the canoes built by the Native Americans were speedier and more mane uverable than the small boats made by Europeans.Next, the author gets into a discussion about the reasons for the fall of the Inca Empire.à During this discussion we learn that while the Europeans used metal to make tools, the Indians used it for tokens.à Moreover, the Europeans had used horses while invading the Inca Empire, and the Indians did not have the technology to beat the intruders on horses.à Still, the Inca Empire collapsed mainly because of disease in addition to factionalism.à There had been a civil war after the Native Americans had clashed with the Spanish.à Smallpox and various other epidemics were also responsible for the fall of the Inca Empire.The first part of Mannââ¬â¢s book also tackles the controversy surrounding the number of Native Americans in Pre-Columbian America.à Scholars have disagreed on the population of the Indians.à Whereas Dobyns believed that there were around one hundred million Native Americans living before the fall of the Inca Empire; Henige argued that the population was much less.à Yet, as Mann points out, there is virtually no evidence to suggest that the population of Native Americans was little.In addition to the above, the first part of the book deals with the Aztecs.à According to scientific evidence, the Aztecs were more sophisticated than we had previously believed them to be.à The Greek ââ¬Å"thinker-teacherâ⬠model prevailed among them as ââ¬Å"tlamatini.â⬠ââ¬Å"Part Two: Very Old Bonesâ⬠provides scientific evidence linked to the skeletons of Lagoa Santa that were found in Brazilââ¬â¢s caves to conclude that the Indians and the Siberians share common ancestry.à Agriculture, too, is a focus of this part of Mannââ¬â¢s book.à According to the author, the Indians began breeding maize right from scratch given that the crop had no ââ¬Å"wild ancestor.â⬠à With the development of maize, the Mesoamerican life was further advanced.à The Olmec c ivilization is mentioned as an example of the high culture that was promoted due to advancement in agriculture.Mann also provides evidence that the Mesoamerican cultures made use of calendars, in addition to wheels.à However, the wheels were used only for small toys.à This is because the Mesoamericans were geographically isolated, and therefore did not have access to other peopleââ¬â¢s ideas on wheels.ââ¬Å"Part Three: Landscape with Figuresâ⬠is where Mann brings all of his evidence together to conclude that there are things we have to learn from the Indians.à He discusses the Maya, and points out that the civilization was active in transforming land.à Additionally, the author describes the unique use of fire by the Indians in this part of the book.à Apparently, the Indians used fire to benefit the plants as well as encourage the abundance of some animals.Mann points to the mistake of holding racist views about the Indians in understanding their unique cultu re given that such views cloud our receptiveness to reality.à As a matter of fact, theà Indians had reached their optimal level of environment.à Before Christopher Columbus arrived on the continent, however, the Europeans had changed the landscape created by the Indians.AnalysisIndeed, Charles C. Mann is correct in his belief that we have been collectively fed in with the myth that the Native Americans were culturally backward.à In point of fact, this myth does not surround the Indians alone.à Rather, we are made to believe that all civilizations before the major ones as we know them ââ¬â the Egyptians, the Greeks, the Muslims, and the United States ââ¬â were culturally backward.We further tend to believe that it was almost impossible for the civilizations of old to perform the kinds of amazing deeds that we perform today, with respect to our technology.à And so, scholars struggled for a long time trying to understand how the ancient Egyptians built the pyra mids without our present technology.à This struggle to understand was led by speculation.However, speculation is unnecessary when scientific facts are before us.à So, we are aware that the ancient Egyptians had their own technology to build the pyramids.à We do not understand the exact nature of that technology.à We may only know from the evidence we have gathered thus far that some of the civilizations of old were far more sophisticated than we had previously imagined them to be.à This is the case with the Indian civilization.à Perhaps, this was also the case with the people of the Stone Age, who might have developed themselves in terms ofà philosophical thinking if nothing else.The fact that we do not possess tomes written by people of the Stone Age or the Indians, does not necessarily lead us to the conclusion that the civilizations in question were less developed or evolved than we are.à Rather, those civilizations used their intellectual capacity in a dif ferent way.à Believers in the scriptures which recount the story of Adam and Eve would all agree that the essential human being has not changed through the ages.à Based on this view, only that which civilizations focus upon in their own time is likely to vary from civilization to civilization, and the human being is the same as he was in the beginning, that is, a being that is curious and would like to see change.The main strengths of Mannââ¬â¢s book are its lucid language, and the vast amount of evidence collected by the author.à Mann makes his book extremely interesting by addressing old myths, and describing the facts that must replace the myths.à The book describes unique fruits, for example, that we had previously supposed to be wild.à Even so, the unique fruits consumed by Indians were as nutritious as todayââ¬â¢s fruits.à Mann describes interesting fruits with flavors like vanilla ice cream, for instance, and others that contained high levels of vitami n C and protein.The discussion that this book is made up of is very valuable in helping us understand faulty perceptions.à According to the author, ââ¬Å"Given the charged relations between white societies and native peoples, inquiry into Indian culture and history is inevitably contentious.â⬠à To put it another way, white societies may have deliberately kept us away from understanding the significance of the Indian culture.à I believe that this is untrue, given the white societiesââ¬â¢ emphasis on knowledge.à Moreover, I trust that the mention of racism should not have been a part of this book.à After all, the book was published in a white society to uncover the reality ofà the Indian civilization.à As a matter of fact, given the importance of the scientific evidence in the book, it is expected that this book will be studied in white societies for a long time to come.Works CitedMann, Charles C. 1491: New Revelations of the Americas Before Columbus.
