본 연구는 한 중 교역이 향후 지속적으로 증가할 것이며, 중국경제의 발전 속도 등을 감안할 때 부품산업이 양국간 교역에서 매우 중요한 위치를 점할 것으로 판단하여, 한국산 부품산업 중 정밀기기부품군의 품목들이 중국시장에서 가지는 경쟁력의 정도를 분석하였다. 연구 목적의 달성을 위해 정밀기기 12개 품목에 대한 2006년-2013년까지의 수출입통계를 수집하였고, MCA지수를 활용하여 동 품목이 중국시장 내에서 가지는 경쟁력의 정도를 조사하였다. 분석결과, 경쟁력 지수 및 추이를 볼 때, 광섬유 및 광학요소, 속도계 및 적산계기는 중국시장에서의 경쟁력이 거의 확보된 것으로 나타났으며, 특히 기타정형외과용기기 및 부품은 중국시장에서의 경쟁력이 최근 급상승하고 있는 것으로 나타나 향후 한국산 정밀기기부품 중 대 중국 수출전략 품목으로 성장할 가능성이 매우 큰 품목으로 조사되었다.

고객이 제품을 구매할 때에는 항시 구매패턴이 생기기 마련인데, 이러한 구매패턴을 찾아 나가는 과정을 장바구니 분석이라 부른다. 장바구니 분석은 Microsoft Association Algorithm에서는 두 가지 단계로 구성되어 있는데, 첫 번째 단계는 빈발항목집합을 찾아내는 과정이고, 두 번째 단계는 첫 번째 단계에서 찾은 빈발항목집합을 근거로 하여 이들의 중요도를 비교하는 단순한 계산과정이다. 빈발항목집합을 찾아내는 첫 번째 단계는 장바구니 분석에 있어서 핵심부분임에도 불구하고, OLAP 큐브에 적용할 때에는 추적분석이 불가능해지거나 허구의 빈발항목집합이 생성되는 등 여러 문제가 발생하게 된다. 본 연구에서는 장바구니 분석에 있어서 추적분석을 가능하게 하고 실제의 빈발항목집합만을 생성시키는 새로운 OLAP 큐브 구조의 설계법을 제안하고 있다.

One of main findings of the competitiveness relation is rapid increase of Chinese influence on the southeast Asian market. While Japanese market share is decreasing, Chinese market share is continuously increasing in the market. It is the same regardless of types of production phases. Analysis based on gravity model shows that in general Chinese exports is crowding out Korean and Japanese export to the market. The magnitude of the effects on Korean exports is larger than on Japanese exports. Also, It is found that the directions of the effect of Chinese exports on Korean and Japanese exports are different by production phrases. For all processed goods, increase of Chinese exports decreases both Korean and Japanese exports to the market. However, for some final goods such as transport equipment and food & beverages for household, Chinese exports is increasing Korean and Japanese exports to the market.

With the shift of the electric power industry from a regulated monopoly structure to a competitive market environment, the focus of the transmission expansion planning has been moving from reliability-driven transmission expansion to market-based transmission expansion. In market-based transmission expansion, however, a growing demand for electricity, an increasing number of transmission bottlenecks, and the falling levels of transmission investment have created the need for an incentive to motivate investors. The expectation of profit serves as a motivational factor for market participants to invest in transmission expansion in a competitive market. To promote investment in transmission expansion, there is an increasing need for a systematic method to examine transmission expansion for investment incentives from multiple perspectives. In this paper, the transmission expansion problem in a competitive market environment is formulated from ISO and investors' perspectives. The proposed method uses parametric analysis to analyze benefits for investors to identify the most profitable location and amount for transmission addition. Numerical results are presented to demonstrate the effectiveness of the proposed method.

Recently, Korea's electric industry is in the midst of a period of profound changes in the structure and function, including the introduction of market competition in the generation sector. Korea is in the early stages of market competition, so the market price is chosen by generation costs but will be chosen by bids in future. Therefore, the profits of generators is determined by market pool price and the prospects of pool price are very important for new capacity investment determination of generators and IPPs. This study analyzes hourly marginal costs and LOLP considering basic generation mix and characteristics, develops the relationship of pool price using the above in competition market, and proposes basic direction for profits variation and supply-demand analysis in the electric market in future.

Changes in consumer purchasing patterns due to construction of large Western-style commercial buildings and introduction of new purchasing methods in South Korea in the 1990s led to a gradual decline in traditional markets. Under such a new environment, Yukgeori market, one of Korea's exemplary markets, has continued to develop and survive, while maintaining the traditional market form of Korea, both physically and operationally. Therefore, to find the characteristics of spatial configurations supporting the revitalization of traditional market, we deduced social attributes of spaces in street network of Cheongju city and the neighborhood including Yukgeori market by calculating the depths of nodes in the network using analysis models based on space syntax. The results illustrated that long street with the function to attract people and acts as a bridge of traffic and communication between highly modernized commercial area and traditional market can lead to continuous win-win development of both areas and the revitalization of traditional market through the promotion of social activities in the market. We expect that sound and sustainable development of contemporary cities, which lost tradition, will be achieved through the results of this study.

This study investigates empirically the export competitiveness of Korea and Japan in America by calculating 4 indexes such as market share index(MSI), export similarity index(ESI), market comparative adventage index(MCAI) and market share expansion ratio(MSER)-export similarity deepening ratio(ESDR). The empirical finding of this analysis shows that Korea is competitive in the labor-intensive products and Japan in the technology-intensive products. This result also meets the general understandings that Japan is superior to Korea in the export competitiveness such as value added of goods, etc. Therefore, in order to strengthen the export competitiveness of Korea in the US market, it's desirable for our firms and government to improve the quality of product ranges by developing technologies focused on the higher value-added products.
