  • There are lots of specialized graduate schools such as law school, medical school, business school. These specialized graduate schools has been designed to train the special experts practically from 1990s in Korea. For all that, there are no specialized graduate schools supported by the Small and Medium Business Administration(SMBA). So we will research the establishment plan of SME(Small and Medium Enterprise) specialized school for the development of SMEs. Recently, the SMBA supports the 2 types of graduate school such as the entrepreneurship graduate school and consulting graduate school. However, it is clear that these 2 types of schools are yet insufficient in terms of efficiency and redundancy. As the representative specialized graduate schools are law school and MOT(Management of Technology) in Korea, we do the comparative study with law school and MOT school. Through the comparative study, we can find some implication for SME specialized graduate school. As a result, the SME school has to need the training system such as the special master's and doctor's degree, over 3 year course work, daytime class, many practical professors, specialized programs with industry like the MOT school. In conclusion, we suggest that : First, the SME specialized graduate school has to be designed for potential SME consultants. Second, the entrepreneurship graduate school and the consulting graduate school can be integrated into the SME specialized school easily. Third, the SME specialized graduate school can have new educational models.

  • This thesis examines the problems faced in the clearance procedures of Korea's e-customs system for which improvements are necessary, and suggests various ways of overcoming those problems. Practical implications regarding the advancement of Korea's e-customs system are as follows. First, the substructure of the e-customs clearance system, which is the basis for the establishment of a global single window, should be developed into a more modern and advanced system. Second, additional improvements in the law are required to render the broad array of Internet-based export and import documents legally binding. Third, customized services should be provided in order to improve the operating efficiency of the e-customs clearance system. Fourth, the reputation of Korea's e-customs clearance system should be raised via the strengthening of a cooperative system between concerned parties, including exporters and importers. This innovative approach to systematic improvements will come about when we can simplify current customs clearance procedures and establish a fairer customs inspection administration regime. Additionally, when we review the methods intrinsic to our customs system, we must emphasize the urgency of proper completion of related systems and arrangements in the trade business and similar fields.

  • General aviation and air transport are two wings of the civil aviation industry. Chinese air transport is developing rapidly, and has become the world second air transport system only second to US since 2005. However, Chinese civil aviation is far behind the world average level, and cannot meet requirements of economic construction and social development. The transition and structural adjustment of Chinese economy provide the general aviation with a unprecedented broad market. The prospect of general aviation is promising and anticipated. The development of general aviation industry needs the legislative supports, and the current legislative conditions of Chinese general aviation are undoubtedly far behind the realistic requirements. Accelerating the legislation in Chinese general aviation industry requires scientific legislation concept. First, Legislation must promote development of general aviation industry. The general aviation will serves as a Chinese emerging industry that boosts domestic demand, promotes employment and expedite domestic economic development. We should, based on both the concept of promoting the industrial development of general aviation and national industrial planning, enact and rectify relative laws and regulations. And we should also straighten out the relationship between aviation security and industrial development and promote the revolution of low-altitude airspace management in an all-round way, in order to improve the utilization rate of airspace resources, classify and establish airspace, simplify examination and approval procedure and intensify operation management. In addition, what we should do is to expedite the infrastructure layout construction, guide the differentiated but coordinated development of general aviation industries in various areas, establish a united supervision mechanism of general aviation, redistrict the responsibilities of Chinese Air Control Agency and set up legislation, law enforcement and judicial systems with clarified institutions, clear positioning and classified responsibilities, so as to usher in a new era of the legislative management of Chinese general aviation industry. Second, shift the focus from regulations to both regulations and services. Considering the particularity of the general aviation, we should use American practices for reference and take into account both regulation and service functions when enacting general aviation laws. For example, we should reduce administrative licensing and market supervision, and adopt "criteria" and "approval" management systems for non-commercial and commercial aviation. Furthermore, pay attention to social benefits. Complete social rescuing mechanism through legislation. It should be clarified in legislation that general aviation operators should take the responsibilities of, and ensure to realize social benefits of environmental protection and ecological balance .Finally, rise in line with international standards. Modify Chinese regulations which is inconsistent with international ones to remove barriers to international cooperation. Specify basic legislative principles. One is the principle of coordination. Realize coordination between the civil aviation and general aviation, between military aviation and civil aviation, and among departments. Two is the principle of pertinence. The general aviation has its own rules and specialties, needing to be standardized using specialized laws and regulations. Three is the principle of efficiency. To realize time and space values of general aviation, we should complete rules in aerospace openness, general aviation airport construction, general aviation operations, and regulation enforcement. Four is the principle of security. Balance the maximum use of resources of Chinese airspace and the according potential threats to Chinese national interests and social security, and establish a complete insurance system which functions as security defense and indemnificatory measure. Establish a unified legal system. Currently, the system of Chinese general aviation laws consists of national legislation, administrative laws and regulations and civil aviation regulations (CAR). Some problems exist in three components of the system, including too general content, unclear guarantee measures, incomplete implementation details, and lacking corresponding pertinence and flexibility required by general aviation regulations, stringency of operation management and standards, and uniformity of standards. A law and regulation system, centered on laws and consisting of administrative laws regulations, industrial regulations, implementation details, industrial policies and local laws and regulations, should be established. It is suggested to modify the Civil Aviation Law to make general aviation laws complete, enact the Regulations of General Aviation Development, and accelerate the establishment, modification and abolition of Chinese general aviation laws to intensify the coordination and uniformity of regulations.

  • An exergy analysis is carried out for the regenerative steam-injection gas turbine systems which has a potential of enhanced thermal efficiency and specific power. Using the analysis model in the view of the second law of thermodynamics, the effects of pressure ratio, steam injection ratio, ambient temperature and turbine inlet temperature are investigated on the performance of the system such as exergetic efficiency, heat recovery ratio of heat exchangers, exergy destruction, loss ratios, and on the optimal conditions for maximum exergy efficiency. The results of computation show that the regenerative steam-injection gas turbine system can make a notable enhancement of exergy efficiency and reduce irreversibilities of the system.

  • The objective of this study is to find out whether Korean main banks may have efficiency against Indian major banks. For this purpose, DEA analysis is used for checking relative efficiency levels. The study proposes, as a result, Shinhan bank, Woori bank and Kookmin bank in Korea may consider entering into Indian banking industry because these three banks have relative efficiency against main Indian banks like Yes bank, ICICI bank. The results of the study comply with actual facts since Shinhan bank already came to Indian banking market at first. Shinhan bank have three branches like Mumbai, NewDelhi etc. Wooribank also entered into India in 2012 as second case among Korean banks. But Kookmin bank did not come to India yet so they should consider coming to India. As a preliminary measures, they can send one person as a expatriate to survey the Indian banking industry like KDB in Korea. If they can utilize their core competence in real estate field at India, they may positively think about entering into India as quickly as possible. Although many Korean firms have penetrated into Indian market recently, they almost belong to manufacturing sectors so Korean service firms like banks should consider more coming to India because the most hot sector for FDI in India remain service sector and many foreign service firms already rush to Indian market. If Korean service firms like banks delay FDI further, good market opportunities would not be there any more. DEA analysis can be one of tools to check investment feasibilities. Since India becomes a compulsory subject for most of Korean firms, to increase possibilities of success in India, such Korean banks may consider applying fast-mover investment strategies to the Indian business fields.

  • Purpose - The logistics industry is often featured by its location relevance and industrial concentration. Industrial concentration is conducive to the effective transmission of information by reducing transaction costs and improving transaction efficiency, thus promoting the development of trade. The main purpose of this paper is to measure the spatial total factor productivity and location quotient of the logistics industry in Korea, and to study the impact of the logistics industry efficiency and agglomeration effect on import and export trade in Korea. Design/methodology - First, used the spatial stochastic frontier method to measure the spatial total factor productivity of the logistics industry in Korea, this serves as the efficiency index of the logistics industry in various regions of Korea. Second, calculated the location quotient (LQ) of the logistics industry to measure the industry's concentration degree. Third, employed a spatial econometric model to analyze the impacts of factors such as the efficiency and concentration levels of the logistics industry on import and export trade in Korea. Findings - This study's main findings can be summarized as follows: this study found that the overall efficiency of the logistics industry in Korea needs to be improved, even though it showed an upward trend in all regions of the country; Moreover, the agglomeration level of Korea's logistics industry needs to be improved; Finally, the positive spatial correlation and industrial agglomeration effect of Korea's logistics industry had a positive impact on the country's import and export trade. Originality/value - This study is innovative in terms of research perspective and methods. Most of the previous studies have measured the development level of the logistics industry using the logistics performance index (LPI), Fewer studies have assessed through the spatial total factor productivity and location quotient of the logistics industry in Korea to measure the efficiency index of the logistics industry in various regions of Korea and concentration degree, as well as there was almost no study on the impact of logistics industry efficiency and agglomeration effect on import and export trade in Korea. This study addresses this limitation by analyzing the impacts of the efficiency and agglomeration effect of the logistics industry on import and export trade in Korea.

  • In recent decades, exergy analysis has been holding spotlight as a useful tool in the design, assessment, optimization, and improvement of energy system. This paper presents the results of the energy and exergy analysis of a steam turbine cogeneration system for industrial complex using two efficiency concepts of conventional one and exergetic one. In order to obtain the destroyed exergy of each component, mathematical analysis is conducted by using exergy balance and the second law of thermodynamics, according as the parameters are changed, such as the ratio of returned process steam, process steam supplied, temperature and pressure of boiler and power. The computer program developed in this study can determine the efficiencies and exergy destroyed at each component of cogeneration system. As a result of this study, a component having the largest destroyed exergy was boiler. And closed and opened feedwater heater had the lowest one. The affects to the cogeneration system due to the variation of process steam flow and return rate of condensed water is shown that the total electric power efficiency(${\eta}_E$) is decreased as increasing the return rate of condensed water under constant process steam flow. As the boiler pressure is increased for the more production of electricity, the efficiency of cogeneration system was decreased.

  • This paper analyzes the relationship between income distribution and energy consumption from a Pareto optimal approach. For this purpose, the causality relationship between electricity consumption per capita (kWh) with respect to country groups and energy consumption per capita (kg of oil equivalent) along with gross domestic product per capita was analyzed. In addition to this purpose, a Pareto analysis was conducted to determine the countries with the highest per capita national income, how much of the world total energy they consume, and whether the law of power in the energy and electricity markets exists. Finally, the impact of official development assistance provided to low-income countries by high-income countries on the low-income countries' electricity and energy consumption was analyzed. In other words, it was questioned whether pareto redistribution policies serve the purpose or not. The Engle-Granger causality approach was used in the analysis of the causality relationship between variables. Our analysis indicated that, first, the energy data of the country groups may be inadequate in revealing income inequalities. Second, the existence of Pareto law of power and global income inequality can be explained based on energy data. Finally, Pareto optimal redistribution policies to eliminate income inequality remain inadequate in practice.
