Urban railway started its operation in August 15, 1978 in Korea. Nowadays, it is being operated in Seoul, Busan, Incheon, Deagu, GwangJu, and Daejeon, and it is playing a major role in mass transportation. Urban railways can provide rapid and convenient transportation to citizens in eco-friendly and energy saving way. However, urban railway operating organizations have been in financially difficult conditions due to the enormous debts borrowed for the construction of railways. Urban railway operating organizations are under pressure to improve its difficult financial conditions through the efficient management of the organization. The management and operation efficiency of urban railway organizations have been evaluated since 1993 by Ministry of Public Administration and Safety to make those organizations more competitive, responsible and efficient. However there are some limitations in evaluation since they do not reflect the relative size of organizations, relative newness of facilities, etc so that it's not objective and loses fairness. This study proposes an improved method for the evaluation of safety.

This thesis has an intention to examine how much Bobos, which has appeared as a new ruling class in the age of digital information economy, has had an influence on the fashion design and which aspect Bobos fashion assumes specifically. The existence of Bobos in Korea and its cultural disposition are examined. To do so, questionnaire survey has been performed for 400 persons. According to the result, it is shown that they control themselves thoroughly through exercise and have much interest in their health; for example, they prefer organic agricultural products and nonpolluting foods. They also consume goods reasonably, emphasizing on their own individuality, rather than purchase high-price articles for no good reason, and enjoy their life while seeking for success in the society. Such a disposition is almost same as that in the U.S, showing a small difference in the occupation or origins. It is examined which aspect Bobos fashion design, a new trend, assumes in more detail. Bobos seeks for a thing that is not cheap, has a recognized brand, and is not behind the fashion. They like the nature friendly, classical, and not vulgar thing. design should be casual and practical, and the quality of the material should be good. Especially, an individual disposition is emphasized in Bobos fashion, in which they disregard a brand and try to be the subject of a trend, by creating a fashion by themselves, to express their originality freely. Bobos fashion the first style it harmonizes the appear things not to be matching with each other and depending on pursuing the mix & match. The second style of Bobos fashion nature is friendship and fight. The hazard which it does like that the fact that it attempts is the composition characteristic of idea. The namely design is an utility cheap assuredly with high-class characteristic of subject matter is not a recognize cheap. The third style of Bobos fashion is expressed in nostalgic about the art. Of course Bobos style is not a possibility fashion as main stream of doing still today, but the effect of Bobos is magnified gradually from cultural, social, economic area. It analyzes style is a tendency where trend of the consumer is gradually converted marketing. This paper is meaningful in the sense that Bobos class, which has not been examined yet systematically, and the fashion are connected closely, and the fashion trend in the next is examined.

Green/climate technology has been emphasized as a growth engine that can boost the global economy via environmentally friendly products. Recently, SMEs in Korea have been recognized as a critical actor in the globalization of green/climate technologies. However, there has been no survey and few studies on the satisfaction level of the support for the overseas expansion of SMEs in the green/climate technology field. Therefore, this study aims to support a policy for the establishment of SMEs' green/climate technology by investigating and analyzing expert opinions on SMEs. Through a literature survey, support policies were classified into four types, and then according to the types, satisfaction factors and obstacle factors for overseas expansion were derived and analyzed. In the results, the SMEs overall showed low levels of awareness and satisfaction and were found to be struggling due to all obstructive factors. In addition, the most important success factor for overseas expansion was found to be the policy related to funding support. Thus, it is necessary to improve the accessibility, advertisement, and support strategies of support policies, and in particular, appropriate budget allocation should be made available by considering the characteristics of companies.

As it is known, during the Second World War Greece has fought on the side of the allies and the end of the war found the country on the winners' side. However, the struggle for authority right after 1945 was merciless and extremely difficult, as well as dangerous for the course of the country to the future. The political powers were divided between the legal authorities that were represented by the king and formed the exiled government on the one hand and the part of the resistance teams and the rebels of the left that had a soviet friendly direction on the other. Thus, the start of a civil war was just a matter of time. It fin ally started in 1947 and lasted for more than two years. The consequences were disastrous for the country's economy and decisive for the future course of Greece. The national army prevailed with the help of, mostly, the English. Royal parliamentary democracy was established with a clear political turn to the west, as a completion and adaptation of the Agreement of the Great Powers at Yalta. Art had a 'similar' route. Dipolar, contradictory: conservative choices on the one side, and a will for pioneering inspiration and perspective on the other side. The 'dominate' trend was first evident in sculpture and mainly in the public monuments. Their construction aimed mostly at the public propaganda and at the promotion of the sovereign ideology. On the one side we have the public sculptures composed of faces of contemporary heroes or leading figures of the civic war and the national resistance. On the other side we have monumental statues mainly that appeal to a 'public' outside of the country's borders and mostly of the north borders, where there are countries with a communistic regime, like Bulgaria, Serbia and Albania. Their subject is derived from the heroic events of the Balkan Wars (1912-1913) and ancient historical figures like Alexander the Great as the Greek army leader, his father, Philippos II and Aristotle, who was of a north-Greek origin. The political message is twofold: on the one side the 'inner enemy' the communists that were defeated and the promotion of the new liberal social system and on the other side the north neighbours, which not only represent the East Block, but they also conspire the history and the culture of the Greeks. This is the way how the 'Cold War' was resulted in a full and totalitarian expression in art.

PVC was chosen as a plastic product that can cope with lead, a radiation shielding material that is widely used in medical institutions. In addition to radiation shielding clothing, we want to evaluate whether it can be used as a medical device component and industrial shielding material in low dose areas. Commercial PVC has a density of 3.68 g/㎠ and can be positively expected sufficient shielding effect in certain radiation areas such as material flexibility and economy efficiency, and can be transformed into various forms and used as a lightweight shielding wall. The shielding performance was tested by adjusting the thickness of 5 sheets of 3mm PVC in the range of medical radiation used for clinical examination in medical institutions. Shielding performance against effective energy was evaluated based on tube radiation voltage of medical radiation. The thicker the PVC, the lower the tube voltage and the lower the effective energy, the greater the shielding effect. The shielding effect was 70% at 12mm thickness and 80kVp tube voltage. Therefore, the shielding effect of PVC material has a high dependence of thickness. In the future, continuous research is needed to make thin and light eco-friendly products while improving shielding performance.

Great efforts have been made worldwide to reduce the Green House Gas (GHG) emission following the "Kyoto Protocol" declared during the United Nations Framework Convention on Climate Change in 1997. Many industries have restructured to meet the standard set by the Protocol. However, no clear guidance has been established for the purpose of reducing the GHG emission in construction industry. In addition, no significant effort has been made to conserve the energy during construction activities. For more effective energy saving in construction industry, it is essential to collect data about energy consumption, quantity of environmental emissions and costs. However, most studies on sustainable construction have been concentrated on the use of equipment, maintenance and repair works during construction due to the difficulties of collecting such data. This study suggests a method to select the most environmentally friendly equipment combination for earthwork with comparing environmental loads and costs using the database of Life Cycle Inventory in the Ministry of Knowledge Economy and Ministry of Environment of Korea.

The construction industry has been a major player in Korean economy growth and it has been accountable for more than 15% of GDP during the last decade. However, fast-growing construction industry has also produced some unpleasant side-effects. Environmental problems are identified one of the main issues in the Korean construction industry and they are closely related to minimizing the carbon emission and delivering environmental-friendly green products. The movement of green construction, now, is considered the next driving force for the industry which has significant impacts on the future. This research investigates this green construction while focusing on governmental policy implications such as green certificate for construction products. Green building has long been recognized as the leading green construction product and the green trends have expanded to infrastructure construction such as road construction. Therefore, this research concentrates on various green road certification processes in the United States in order to develop a framework for Korean green road certification. In doing so, some of the green roads application has also been analyzed. This research intends to provide background information for Korean green construction policies, especially on green road certification.

Utilization of cultural contents is more and more increasing as it is believed to improve local problems and provide historical values. This kind of business is positive in terms of the fact that it attracts visitors into local areas and activate local commercial areas. Under this trend, the construction of specialized streets is required to be approached with first priority to solve problems of cities. So to speak, it's more important to solve intrinsic problems found in local communities and then approach cultural contents step-by-step rather than constructing new spaces with first priority. Moreover, cultural contents should accompany economic aspects which result in local community-friendly and sympathetically concentrated values. Under this sentiment, the efforts to suggest economic ripple effects for government local government's businesses using cultural contents are very important. This study analyzed how much economic ripple effects is yielded by reflecting cultural contents. As the result of analysis, specialized street with cultural contents applied are proved to be more concentrated on multiplier of expediting employment, income and tax and tourism industry than service industry. On the contrary to this, service industry showed more concentrated multiplier of expediting production, income, added values and chain reaction effect (coefficients for influence and sensitivity for front and rear side of tourism industry. Based on these results, construction of specialized streets with cultural contents applied is proved to help synergy effects for local economy.

The policy-making and technological development of eco-friendly automobiles designed to increase their supply is ongoing, but the internal combustion engine still accounts for approximately 95% of automobiles in use. To meet the stricter emission regulations of internal combustion engines based on fossil fuels, the proportion of after-treatments for vehicles and (ocean going) vessels is increasing continuously. As diesel engines have high power and good fuel economy in addition to less CO2 emissions, their market share is increasing not only in commercial vehicles, but also in passenger cars. Because of the characteristics of the diesel combustion, however, NOx is generated in localized high-temperature combustion regions, and particulates are formed in the zones of diffusion combustion. LNT and urea-SCR catalysts have been developed for the after-treatment of exhaust gas to reduce NOx in diesel vehicles. This study examined the effect of a containing promoter on SCR catalysts to cope with the severe exhaust gas regulation. The de-NOx performance of the Mn-SCR catalyst was the best, and the de-NOx performance was improved as the ion exchange rate between Mn ion and Zeolyst was good and the activation energy was low. The de-NOx performance of the 7Cu-15Ba/78Zeoyst catalyst was 32% at $200^{\circ}C$ and 30% at $500^{\circ}C$, and showed the highest performance. The NOx storage material of BaO loaded as a promoter was well dispersed in the Cu-SCR catalyst and the additional de-NOx performance of BaO was affected by the reduction reaction of the Cu-SCR catalyst. Among the three catalysts, the 7Cu-15Ba/Zeolyst SCR catalyst was resistant to thermal degradation. The same type of CuO due to thermal degradation migrates and agglomerates because BaO reduces the agglomeration of the main catalyst CuO particles.
