This paper is about an optimal investment portfolio strategy. Financial data of stocks, bonds, and savings from January 2. 2001 through October 30. 2009 were utilized in order to suggest the optimal portfolio strategies. Fundamental analysis and technical analysis were used in stocks-related strategy, whereas passive investment strategy and active investment strategy were used in bond-related strategy. The score is assigned to each stock index according to the suggested strategies and set trading rules are based on the scores. The simulation has been executed about each 29,400-portfolios and we figured out with the simulation result that 26.75% of 7,864 portfolios are more profitable than average stock market profit (22.6%, Annualized). The outcome of this research is summarized in two parts. First, it's the rebalancing strategy of portfolio. The result shows that value-oriented investment(long-term investment) strategy yields much higher than short-term investment strategies of stocks or active investment of bonds. Second, it's about the rebalancing cycle forming the portfolios. The result shows that the rate of return for the portfolio is the best when rebalancing cycle is 12 or 18 months.

After Chinese reforms and market opening, China actively started working on ways to attach importance to the ocean and it's maritime strategy has been developed and carried out by external and internal factors. We can take two things as external factors attributed to China's marine strategy. The first one is maritime environment change in the East Asian region and the second one is the strategic importance of Taiwanese Straits and the South China Sea. And we can take about national strategy, security strategy, and change of foreign policy as internal factors. China recognizes the ocean as a major step to achieve a goal of national development. The main goal of China's marine strategy in the 21st century is to secure marine transportation and marine resources and to make peaceful maritime environment in the ocean to keep up with their economic development by opening itself to the world. China has strengthened their defense abilities to act against threat of national security by modernizing sea forces and increased national power by building up the marine power. It is expected that China will continue to seek more aggressive maritime strategy on matters of national security as well as pour heir efforts into making economic development and obtaining energy resources. This will also be one factor making new dynamics between countries in and around the East Asian region.

This study was initiated to inquire as to why Wal-Mart failed in the Korean market. For multi-national corporations, environmental differences such as cultural and social differences among countries require business strategies to vary country by country. In Korea, Confucian Ethics are penetrated in every aspect of people's lives. An important aspect of Confucian Ethics is the role and responsibility of women in society. Considering this, businesses need to understand Korean women's preferences as consumers and develop business strategies accordingly. This study emphasizes that IS strategy is one component of the business strategy and, as such, must be rooted in business issues. Understanding that IS strategy should fit to national contexts, this study investigates the underlying process in which IT-based strategic capability is developed according to national context to gain competitive advantages.

Korean government has promoted the projects of National Geographic Information Systems since 1995 and the utilization level of Korean National Spatial Data Infrastructure based on them has also developed. However, due to the limit to domestic market size and the legal regulation on prohibition of large sized companies' expansion into domestic spatial information markets, Korean spatial information markets are tied up in term of industrial competitiveness. To overcome those problems and evade the domestic red oceans, it is necessary to find new one in overseas' blue ocean markets. It is estimated that overseas spatial information market will be grown to 125 billion-dollar size and the annual growth rate of it will be reached to 10.5% until 2015. Thus, Asian spatial information market has a huge growth potential and it is newly rising blue oceans for Korea. Advanced countries such as Finland, Germany, Sweden, and Japan have already expanded their market size into the newly industrializing countries. To step with advanced countries, it is time to set up the new globalization strategy of Korean spatial information for expansion into newly industrializing markets. The purpose of this study is to analyze the SWOT of domestic spatial information, investigate the status on spatial information of Asian developing countries, and suggest the globalization strategy of Korean spatial information for expansion into them. The globalization strategy can be labelled as K-FBI composed of 4 domains such as Knowledge sharing platform, Frontier, Back to the basic, and Internalization. In near future, the establishment and performance of road map based on the strategy will be the milestone for Korean spatial information companies' advance into Asian developing countries.
