Because of explosive growth in demand for web-based multimedia applications, proper proxy caching for large multimedia object (especially video) has become needed. For a video object which is much larger in size and has different access characteristics than the traditional web object such as image and text, caching the whole video file as a single web object is not efficient for the proxy cache. In this paper, we propose a proxy caching strategy with the constant-sized segment for video file and an improved proxy cache replacement policy. Through the event-driven simulation under various conditions, we show that our proposal is more efficient than the variable-sized segment strategy which has been proven to have higher hit ratio than other traditional proxy cache strategies.

With the advent of new order of international competition, the technology Policy of Korea has been changed from vertical one which focuses on specific technologies or selective industries to a horizontal one which supports R&D activities on a neutral basis. TIP(Technology Infrastructure Policy) is WTO free in the sense that it is Indirect method of supporting technology development and properly defined as a part of government role by OECD. Technology infrastructure is embodied in human capital, and includes also elements of physical capital and knowledge. Hence it is more differentiated than, and distinguished from conventional infrastructure. It implies a need for carefully designed strategy with the recognition of those differences. As a fundamental element of innovation and technological development, technology infrastructure should become the main focus of industrial technology Policy.

This study aimed at proposing a RD&D good practice policy guidelines for energy technology innovation in electric power industry, we identified the success factors on energy RD&D through representative case analysis such as energy RD&D demonstration project and strategy plan, technology road map, etc. Based on a successful case study, we have identified the key elements needed to suggest when setting a RD&D technology innovation policy framework for technological competitiveness in the power industry sector. We have presented guidelines for energy technology innovation direction from the full cycle perspective of RD&D. The energy RD&D innovation system that we have established is meaningful in that the implications are derived and reflected through the case analysis of developed countries. The results of this study are as follows; Enhancement of R&D investment performance, commercialization of research achievements, promotion of export industrialization of electric power industry, establishment of RD&D governance system of power energy, etc.

The trends of economic business environment have been changed to the ultimate competion, diverse market and need of new technology. To enforce the international competitive power, continuous technology innovation should be propelled. But the characteristics of small and medium company make it hard to get lead of market share. The industry of transportation and stevedoring machinery also have the same situation as small and medium company. This paper try to present the way of competitive power. The Strategic technology innovation for the industry of transportation and stevedoring machinery consists of product strategy, process design strategy, infra-structure strategy and R&D. There are benefits and shortcommings to get the competitive power for the industry of transportation and stevedoring machinery. Therefore the onclusion presented that capital for reverse engineering, export policy, human resource, thechnical cooperation with the institutions are required.

ISP(Information Strategy Planning) is the methodology to light the objective and the business system architecture, and to recognize the strategic situation for the establishment of effective information system in an organization. Customer Needs Research is one of the Research Methodology that analyze the customer needs effectively and use to establish the policy and the direction of corporation. Both have the important role to establish the strategy for the corporation. The former can propose the corporate information strategy in MIS, the latter can be used to research the customer needs about a corporation, to establish the business management strategy and to decide the way corporate must head. But each has studied independently and there is no integrated methodology of ISP and Customer Needs Research. Actually, a lot of corporations still establish ISP to increase the business efficiency rather than to satisfy the customer needs. Customer satisfaction is the final objective of all business so that corporations have to find the customer needs through Customer Needs Research and make ISP oriented to customer satisfaction through the result of Customer Needs Research.

IT is the core industry in Korea which has the most international competitiveness and counts for 35% of the total exports of Korea. Nevertheless, it tends to be concentrated in small range of items, a few countries and mostly large companies. Therefore, it is needed for small and medium-sized enterprises which can have prompt decision making processes and various changes to export wide range of items and to diverse countries. This study will introduce 'the fleet-type expansion strategy of overseas export' that is about large and small enterprises perform the appropriate role based on their own character, thus they produce the mutual benefit. This strategy will contribute to improve the export structure of Korea and perform the major role for Korea's IT industry to become the dynamic force for growth in the future.

There are many challenges to solve on how we will use IT infrastructures accepted as the best worldwide level for strength of country's competitiveness. Over the past years, IT environment has been formed to expand the basis of e-Business by policy, but little contributed to management efficiency such as improvement of business productivity through utilization of it. This paper explores the category of the related technology policies by classifying e-Business technologies and presents the problems and developmental directions for those policies by investigating the trends of the policies which have been framed so far. Especially, this article also examines the differences between the technology policy on the road map of 2010 e-Business policy and the IT839 strategy.

The present research applies the Theory of Harmony through Holistic Engagement to the foreign policy of Japan. As the third largest economy in the world and one of the most highly developed countries in the world, Japan is a major international power. Most analysts interpret Japan’s foreign policy through the lenses of realist, exceptionalist, or liberal institutionalist approaches. All the previously mentioned approaches tend to be based on etic studies conducted from the point of view of outsiders. The present interpretation of Japanese foreign policy applies an emic model based on primary sources from the Greater East Asian region and concludes that the Model of Harmony through Holistic Engagement shows considerable explanatory traction in interpreting the direction and development of Japanese foreign policy, in particular in the last two to three decades.

Since its foundation in September 1986, the Korean Society of Water and Wastewater has made a significant contribution to the water sector in Korea over the past 30 years. The 30th anniversary commemorative committee reviewed the establishment goal of the society and its development strategy for organization and present the "Future Vision of Korean Society of Water and Wastewater" for the next 30 years. The future vision of the society is defined as "Aiming for the healthy life and preservation of the environment through the development of water and wastewater technology and experience". Promotion strategies for implementing the future vision are as follows: 1. Leading water and wastewater technology, 2. Develop water and wastewater policy, 3. Strengthen water and wastewater capacity, 4. Reinforce institutional governance. The driving target to be achieved through the implementation strategy is "To lead the global standards of water and wastewater." We also presented national issue, policy issue, and technical issues in the water sector. Climate change, unified Korea, water safety, and national welfare were selected as national issues related to water and wastewater. This approach was taken from the perspective of policy consumers such as citizens, civil society, experts, and local government/industry. By presenting policy issues and technical issues that address national issues, authors have proposed a future policy direction for the Korean Water and Wastewater Society to make critical contributions to national development.
