Purpose - to examine the theories related to the internationalization of multinational corporations as well as theories related to internationalization of small and medium-sized enterprises. Research design, data, and methodology - traditional theories, e.g. eclectic paradigm and behavioral theory and product life cycle etc. were examined and recent advances theories - network theory, entrepreneurship - were also examined to outline the theory of internationalization of firm. Results - the main schools of international researches are divided into two; one is the economics school, the other is the behavioral school. The economics school has considered internationalization as a pattern of investment in foreign markets explained by rational economic analysis of internalization, ownership, and location advantages. Apart from the economics approach, a theory relevant to smaller firms highlights slow and incremental overseas market commitment. Recent research on the network perspective is fast emerging and it can be applied and well explained on the internationalization of smaller firms, focusing on firm behavior in the context of a network of interorganizational and inter-personal relationships Conclusions - Small medium-sized enterprises have been recently rising, however, there has still been little consolidation of literature in internationalization and most of the relevant theories have been still focusing on explaining the globalization of multinational corporations. Little studied on the internationalization in the context of smaller firms which are distinctly differentiated from larger firms including international new ventures, which the motivation to study strongly calls for more information and studied on small medium-sized enterprises.

This paper deals with two problems of optimal portfolio strategies in continuous time. The first one studies the optimal behavior of a firm who is forced to withdraw funds continuously at a fixed rate per unit time. The second one considers a firm that is faced with an uncontrollable stochastic cash flow, or random risk process. We assume the firm's income can be obtained only from the investment in two assets: a risky asset (e.g., stock) and a riskless asset (e.g., bond). Therefore, the firm's wealth follows a stochastic process. When the wealth is lower than certain legal level, the firm goes bankrupt. Thus how to invest is the fundamental problem of the firm in order to avoid bankruptcy. Under the case of different lending and borrowing rates, we obtain the optimal portfolio strategies for some reasonable objective functions that are the piecewise linear functions of the firm's current wealth and present some interesting proofs for the conclusions. The optimal policies are easy to be operated for any relevant investor.

Nowadays, business environment changes with higher consumer demands for corporate social responsibility than before. However, many fashion companies are unaware of such a wave of changing business environment. And they are not so much interested in making any investment or policy for CSR activities. Besides, despite changing environment and consumer demands, there are very few studies dealing with this matter. Thus, this study aimed to find out the proper types of CSR activities for fashion companies. In addition, it also intended to determine potential effects of CSR activities on consumer attitudes and purchase behaviors. The findings are as follows. First, it is found that there are differences in consumers' perceived suitability depending on types of CSR activities of fashion company. Secondly, it is found that the suitability of CSR activities of fashion companies has positive effects on consumer attitudes to fashion companies. Thirdly, the more favorable consumer attitudes to fashion companies owing to their CSR activities are correlated with the higher consumer satisfaction. Fourthly, the more favorable consumer attitudes to fashion companies are also correlated with the higher consumer intention for purchase. Hence, it is required that fashion companies recognize the importance of their CSR activities, and also plan and implement appropriate CSR activities for consumers.

The purpose of this study was to examine the relationship between parental attribution and self-perception in parenting roles according to parenting success or failure situations. A total of 138 mothers who have toddlers in Seoul and other big cities in Korea completed questionnaires, and data were analyzed by paired t-test, Pearson's correlation coefficient, Fisher's Z score, and multi-regression. The results are as follows: First, mothers in parenting success situations showed higher parental attribution than mothers in parenting failure situations. Second, correlations between parental attribution and self-perception in parenting roles turned out to be significantly different between parenting success situations and failure situations. Third, both internal attribution such as ability and effort, and external attribution such as child behavior and task difficulty, significantly predicted self-perception in parenting roles including equilibrium feeling, competence, satisfaction and parenting investment, especially in parenting failure situations. The implications of the difference in parental attribution between parenting success and failure situations have been discussed.

본 연구는 재벌집단의 기업과 비재벌기업으로 분류하여 이들 집단사이에 나타나는 투자행위의 차이점을 유동성제약의 틀 속에서 실증 분석한 것이다. 연구의 기간은 1986년부터 1995년도까지 10년으로 하고 연구의 대상은 연구 기간동안 연속적으로 증권거래소에 상장된 기업으로 한정하여 총 128개의 업체를 표본으로 이용하였다. 표본을 재벌규모별, 장세별, 산업별 분류에 의한 횡단면 분석결과 우리나라 비재벌기업의 경우, 전반적으로 재벌집단의 기업에 비하여 현금흐름이 투자에 대해 보다 더 민감할 것이란 충분한 근거를 얻지 못하였다. 그러나 재별의 범주를 5대재벌기업으로 한정하였을 때는 재벌기업에 비해 비재벌기업들의 투자는 현금흐름에 대하여 민감하다는 결론을 얻어 재벌기업에 비하여 비재벌기업은 정보문제나 유인문제에 직면 할 수 있음을 시사하였다. 규모에 따른 재벌기업의 분석에서는 상대적으로 규모가 작은 재벌의 기업이 규모가 큰 재벌의 기업보다 유동성이 제약되고 있음을 나타냈으며, 장세별 분석에서는 단지 주가의 상승기에 한하여 재벌집단 기업간의 비교에서 현금흐름은 30대재벌, 10대재벌, 5대재벌의 순서로 민감함을 보여 규모가 작은 집단의 재벌기업이 규모가 큰 집단의 재벌기업에 비하여 유동성이 제약됨을 나타내었다. 산업별 분류에 의한 분석에서는 통계학적으로 의미 있는 결과를 얻지 못하였다.

This paper describes the forecast of wholesale price in competitive Korean electricity market using the system dynamics approach. The system dynamics concepts have been implemented with the Ithink software. This software facilitates the development of stock and flow model with information feedback. Using this model, the future wholesale electricity price can be computed hour by hour, quarterly, and yearly. This model also gives the energy planner the opportunity to create different scenarios for the future of deregulated wholesale markets in Korea. Also It will lead to increased understanding of competitive wholesale market as a complex, dynamic system. Research results show that the plant construction appeared in waves of boom and bust in Korean electricity market like real estate construction. That is, the Korea wholesale market's new power plants and the market price will appear the Boom and Bust cycle. It is very similar behavior as real estate industry. In case of consideration of DSM program, The DSM savings lead to a somewhat different timing of the booms in construction and of price spikes. But the DSM programs do not eliminated the fundamental dynamics of the boom and bust. And the wholesale price is maintained at the lower level compared to the case of without DSM program. However, the unexpected result is found that due to the lower market price, Investor make significantly less investment in new CCs, which leads to the higher wholesale price after 2010. It suggests that the DSM Policy must be implemented with the dynamics of competitive Electricity Market.

To investigate the realistic behavior of mass and energy release and resultant containment response during large break Loss of Coolant accident (LOCA), analyses are performed for Yonggwang (YGN) 3&4 nuclear power plants by using a merged version of RELAP5/CONTEMPT4 computer code. Comparative analyses by using conservative design computer codes are also peformed. The break types analyzed are the double-ended guillotine breaks at the cold leg and hot leg. The design analysis resulted in containment peak pressure during post-blowdown phase for the cold leg break. However, the RELAP5/CONTEMPT4 analyses show that the containment pressure has a peak during blowdown phase, thereafter it decreases monotonously without the second port-blowdown peak. For the hot leg break, revised design analysis shows much lower pressure than that reported in YGN 3&4 final safety analysis report. The RELAP5/CONTEMPT4 analysis shoos similar trend and confirmed that the bypass flow through the broken loop steam generator during post-blowdown is negligibly small compared to that of cold leg break. The low pressure and temperature predicted tv realistic analysis presented in this paper suggest that the design analysis methodology contains substantial margin and it can be improved to provide benefit in investment protection, such as, relaxing plant technical specifications and reducing containment design pressure.

Although the generation market is competitive, the power market is easily exercised the market power by one generator due to its special futures such as a limited supplier, large investment cost, transmission constraints and loss. Specially, as Korea Electric industry restructuring is similar US competitive wholesale electricity market structure which discovered the several evidences of market power abuse, when restructuring is completed the possibility that market power will be exercised is big. Market power interferes with market competitions and efficiency of system. The goal of this study is to investigate the market price effects of the potential market power and the proposed market power mitigation strategy in Korean market using the forecasting wholesale electricity market model. This modeling is developed based on the system dynamics approach. it can analyze the dynamic behaviors of wholesale prices in Korean market. And then it is expanded to include the effect of market condition changed by 'strategic behavior' and 'real time pricing.' This model can generate the overall insights regarding the dynamic impact of output withholding by old gas fire power plant bon as a marginal plant in Korean market at the macro level. Also it will give the energy planner the opportunity to create different scenarios for the future for deregulated wholesales market in Korea.
