본 연구는 1997년 정부의 석유제품 수입자유화 조치가 전형적인 과점기업인 국내 석유기업들의 시장행위에 미친 영향을 분석하고자 하였다. 이를 위해 암묵적 카르텔 이론을 기초로 두 가지 지표, 즉 공급량과 정제마진(정제비용과 이윤의 합)에 반영된 국내 석유기업들의 시장형태를 1994년부터 2003년 6월까지의 월별 자료를 이용해 추정하였다. 추정결과는, 수입자유화가 예상되는 시기부터 이미 국내 석유기업들의 공급량은 크게 증가하는 반면 정제마진은 감소하는 현상이 통계적으로 매우 유의적으로 나타나, 국내 석유기업들이 자유화 이전에 암묵적 협조체제를 형성하고 있었을 가능성이 높게 나타났다. 한편 2000년 이후 국내 석유기업들의 공급량은 외환위기 때의 수준을 유지하고 있는 반면 정제마진은 수입자유화 이전에 비해 큰 폭으로 하락한 것으로 나타났으며, 제품별로는 특히 휘발유의 정제마진이 타제품에 비해 통계적으로 가장 유의성 있게 큰 폭으로 하락한 것으로 나타났다. 이는 수입자유화의 영향이 본격적으로 나타나기 시작한 2000년 이후부터 국내시장에서는 모든 석유제품을 대상으로 시장경쟁이 치열함을 입증하는 것으로서, 현재 국내 정유사들의 가격결정이 상호 협조 속에서 이루어지고 있다고 보기는 어렵다. 따라서 정부의 수입자유화 조치는 국내 석유기업들의 시장행위에 큰 영향을 주어 국내 석유제품시장의 구조를 암묵적 협조체제에서 비협조적 경쟁시장으로 만드는 계기가 된 것으로 볼 수 있다.

In the later quarter of the twentieth century, the need for foreign capital is realized among the various countries of the world. Developing countries especially developed multi-pronged strategies to attract foreign capital into the country. One such strategy is the adoption of liberalization policy. Almost all the developing countries started opening their economy, out of the compulsion, to achieve faster rate of economic growth and development. Even a communist country like China adopted liberalization policy as a strategy for accelerated economic growth during 1979. India also joined the race by 1991, when the government announced the policy of liberalization. The importance of FDI extends beyond the financial capital that flows into the country. The huge size of the market in this sector and high returns on investment are two important factors in boosting FDI inflows to power sector. 100 percent FDI is allowed under automatic route in almost all the sub sectors of power sector except the atomic energy. Major foreign investment is made in this sector during 2000 to 2009 is Mauritius with an investment of US$ 4490.96 i.e., 4.24 percent of the total FDI inflows into the country during the period. The estimation of future FDI flow shows a marginal decline in the year 2010. Then from 2011 to 2015 onwards upward trend of FDI was observed.

This study explores how strategic alliance activities are evolving and the factors that impact on the formation and development of airline alliances. Findings show the initiation of regional and more liberalized bilateral, or open skies, agreements have removed some of the impediments to structural changes in international aviation. Airlines in more liberal markets enter into greater numbers and more integrative forms of alliances. Also, airlines, on average, achieve better results of operation if the market is more liberal. Essentially, there is a positive relationship between the developments of alliances and the liberalization of air transport markets. It has been questioned that the US bilateral open skies agreements provide its carriers more access to the global market and countries that do not enter into such agreements with the US risk a loss of traffic. Consequently, open skies agreements may enable carriers who have the freedom to exercise market power to be dominant in the markets. This suggests that regulatory coordination and liberalization of international aviation reinforce each other and should therefore be pursued simultaneously.

The channel of distribution exists for the purpose of moving product from the manufactuerer to the final consumer. In order to satisfy consumer needs, channels provide for the those products to arrive at the right place, at the right time and in the quantity, quality and price desired. Currently, there has been an emerging interest in the improvement of distribution system in many areas of industries and Korean government because of a market liberalizatiion begun at 1989 and still has processed step by step. In the wave of market liberalization, an understanding of the channel of distribution and structure would be very crucial when developing the opportunities of competitive advantages in Korean apparel industry. The purposes of this study were to investigate the determinants of the distribution channel and to identify how to respond to the market liberalization for developing the possible future strategies in the apparel industry. Data for this study were obtained from interviews with managers in apparel company in addition to a questionnaire mailed to over 106 middle management position of apparel company. Data were analyzed by using descriptive statistics. The results of this study were summarized as follows. 1. In the distribution channel of the apparel industry, a vertical marketing system, comprising producer, apparel company, retailer, prevailed without intermediaries such as wholesalers or vendors. Especially, the apparel company controlled marketing channel members. This type of system may reflect added product cost and may be not advantageous to retailers and consumers because most apparel companies are responsible for its own transfortation, storage and stocks after season. 2. In the view of market liberalization, most apparrel companies showed double-edged viewpoints. In terms of positive aspect, it would give stimulus to broaden variety of fashion merchandise and to improve product quality of fashion merchanise which were the most disadvantageous factors in competing with oversea's brands. In terms of negative aspect, it would bring the bankruptcy of small or medium sized apparel firms and the foreign products' penetration in domestic market. From this study, severel recommedations were suggested forward to improve the present condition in apparel industry. They included eliminating the power of apparel company and reinforcing middlemen for more efficient distribution system and for satisfying consumer needs in rapidly changing environment. Also it included government supports, reinforcement of information system, improvement in channel structure, and career development program in conjunction with apparel companies and academic society for improving scientific management and future potential strategies in Korean apparal industry.

The use of renewable energy sources and energy storage systems is increasing due to new policies in the energy industries. However, the increase in distributed generation hinders the reliability of power systems. In order to stabilize power systems, a virtual power plant has been proposed as a novel power grid management system. The virtual power plant plays includes different distributed energy resources and energy storage systems. We define a core virtual power plant technology related to demand response and ancillary service for the cases of Korea, America, and Europe. We also suggest applications of the proposed virtual power plant to the vehicle-to-grid market for restructuring national power industries in Korea.

Services could move over the world where they want to go. Especially, travel services shared 29.4 percent of total world exports, 625 billion dollars in 2004 (WTO, 2005). Tourism is a very important sector in service trade in the world. Of developing countries, Korea has been experiencing remarkable development in female outbound travel market since the complete liberalization on overseas travels in 1989, with about 3.85 million travelers in 2005, 2,000 percent growth rate over 1988. It means woman's social status has been increasing in Korea. Especially, in the study young housekeepers, solely office ladies, and college students were described as very important market segments in Korean woman outbound travel market. They were not only major decision makers, but also executors because of both enough economic power and social status improvement on small sized family. This study indicated that woman outbound travel market gets larger because their buying power and status are going to go improved in Korean social system. It is recommended that marketers be worth watching Korean woman travellers as a major target market through continuos observation and analysis.

FTA is acting as a central axis to accomplish the worldwide trade liberalization as FTA has been globally spreading with competition. As the global economic depression and the trend of new protectionism are getting grave, and the trade liberalization of GATT and WTO is getting delayed, FTA is spread as an alternative. FTA is often called as RTA: Regional Trade Agreement(regional free trade agreement) which takes place mainly around the neighbor nations or regular districts, and these days, it is tending towards agreements between long distant nations, so, it's not limited to the regular districts. Among the FTA agreement items, in addition to the customs abolition, the opening and investment liberalization of service market like finance, communication etc., intellectual property rights are included in the government's target range. Korea also is actively proceeding FTA conclusion. Korean government has concluded the agreements with Singapore, european nations beginning from Chile concluded in 2003, and is proceeding more the negotiations with Japan, Canada, Mexico, India etc. Now in 2009, FTA of Korea-United States is actually waiting for just the passage of assembly ratification. But, if FTA becomes effective, because our domestic market should be entirely opened, it is expected that the blow against our domestic agricultural field which is weak, compared with that of the United States, a nation of worldwide agricultural products, is not an ordinary one. According to it, we need a whole plan to cope with, so, the purpose of this study is to suggest the strategy by comparing and analysing the Korean agricultural competitive power, and to find the other development stratagem.

The liberalization of electricity market and environmental concerns are the major driving forces for the development of Distributed Generation (DG). The mode of grid-connected wind power generation is becoming popular and has matured as a reliable DG technology. The voltage generated by the wind generator is stepped up to the higher voltage by the transformers before connecting to the grid. Operating algorithm of the differential relays for transformer protection used in the wind farms need to be modified to take care of the dynamic nature of fault current caused by the intermittent nature of the wind power. An algorithm for the differential relay is proposed in which dual slope characteristics are adjusted with varying fault level situation according to the wind generator in service as well as with the wind speed. A case study conducted for a typical wind farm shows that the proposed method avoids mal-operation of the differential relay in varying wind power conditions.
