At the 8th National High-Performance Computing (HPC) Committee convened in 2021, the "National High-Performance Computing Innovation Strategy (draft) for the 4th Industrial Revolution Era" was deliberated and the original draft was approved. In this proposal, the Ministry of Science and ICT in KOREA announced three major plans and nine detailed projects with the vision of "Realizing the 4th industrial revolution quantum jumping by leaping into a high-performance computing powerhouse." Thereby the most important policy about national mid-term and long-term HPC development was established and called the HPC innovation strategy (hereinafter "the innovation strategy"). The three plans of the innovation strategy proposed by the government are: Strategic HPC infrastructure expansion; Secure source technologies; and Activate innovative HPC utilization. Each of the detailed projects has to be executed nationally and strategically. In this paper, we propose a strategy for the implementation of two items ("Strategic HPC infrastructure expansion" and "activate innovative HPC utilization") among these detailed plans.

In a VOD server, media data are usually encoded by VBR compression technique such as MPEG, therefore, media stream rates vary. We propose a striping strategy called VCS considering VBR compression in Clustered VOD servers. Simulation are conducted to evaluate and compare the new strategy with a known striping strategy. The results show that the VCS strategy improves the performance.

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.

As today's Information Technology (IT) becomes more global and specialized the importance of Information Technology Architecture (ITA). Based on the case study of e-commerce, this paper presents a systematic approach to Information Strategy Planning (ISP) with ITA. To implementation of strategic approach, ITA is developed to establish e-commerce projects. It is believed that the Chief Information Officer (CIO) will be more receptive to results that include ISP and ITA are combined simultaneously.

The nursing informatics has been booming in Taiwan since 2003 when we started to use the end user computing strategy to promote it. We used Excel 2003, which was well known and used by our clinical nurses, as well as the embedded VBA to teach them how simple information applications could and should be built to meet their information management needs in order to support their professional responsibility. Many cost-effective projects were successfully done and the importance and potentials of nursing informatics started to be noticed. Our training strategy and materials are introduced in this paper.

The purpose of this study is to examine the factors influencing performance of software companies. This model tests various theoretical research hypotheses related to innovation, standardization and technology marketing strategy and software type. Smart PLS (Partial Least Square) 2.0 and SPSS 15.0 have been utilized for deriving the study results. The result of hypothesis testing is as follows. First, standardization and technology marketing strategy positively influence financial performance. Second, innovation, standardization and technology marketing strategy positively influence technical performance. Finally, mobile and non-mobile software companies was shown that innovation, standardization, and technology marketing strategy has different effects to financial and technical performance.

The intensification of the processes of the digital economy development is leading to the transformation of the higher education system. Universities are forced to digitalize their own educational, research, international, marketing, financial and economic activities in order to maintain a competitive position in the global market of educational services. The purpose of the article is to study the role of information and communication technologies in the development of the higher education system and to ensure its adaptability to modern challenges of digital economy. To achieve this goal, methods of content analysis, logical generalization, systematization and a structural-functional method are used. In the article, the authors substantiate the urgency of forming a holistic strategy to ensure the adaptability of higher education to the challenges of digital economy. In the structure of this strategy, the information-technological block is singled out and described. The authors specified a set of positive synergetic effects from the introduction of modern information and communication technologies in the activities of universities.

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.

1995년부터 추진한 국가지리정보체계 구축사업으로 국가공간정보인프라의 활용수준은 높아졌으나, 국내시장 규모의 한계와 대기업의 시장진출에 대한 법률적 규제로 인해 한국의 공간정보 시장은 산업경쟁력 측면에서 정체하고 있다. 이러한 문제점을 극복하고 과열된 국내의 레드오션 시장을 벗어나기 위해서는 새로운 공간정보의 블루오션 시장을 발굴할 필요가 있다. 해외 공간정보 시장은 2015년까지 연평균 10.5% 성장하고 150조원(1,250억 달러)로 성장할 것으로 예측되고 있다. 따라서, 아시아의 공간정보 시장은 커다란 성장 잠재력을 가지며, 한국에게는 새롭게 부상하는 블루오션 시장이 되고 있다. 핀란드, 독일, 스웨덴, 일본 등의 선진국들은 이미 오래전부터 개발도상국의 공간정보 시장에 진출하고 있으므로 선진국과 발을 맞추기 위해서 신흥공간정보 시장으로의 진출 확대를 위한 한국 공간정보의 새로운 글로벌화 전략 마련이 시급한 상황이다. 이 연구의 목적은 국내의 공간정보에 대한 강점-약점-기회-위협 요인을 분석하고 아시아 개발도상국의 공간정보 현황을 고찰하며, 한국 공간정보의 신흥시장 진출을 위한 글로벌화 전략을 제시하는데 있다. K-FBI 글로벌화 전략은 지식 플랫폼 구축전략, 신개척지 전략, 기본 공간정보 공략 전략, 현지 맞춤형 내재화 전략의 4가지 영역으로 구성될 수 있다. 향후 K-FBI 글로벌화 전략에 기반한 공간정보 로드맵의 수립과 시행은 우리 공간정보 기업의 아시아 개발도상국 진출에 큰 디딤돌이 될 것이다.
