  • 휴대용 컴퓨터와 무선통신 기술 발달로 인해 사용자들은 시간과 장소의 구애를 받지 않고 컴퓨팅 환경을 제공받을 수 있게 되었다. 그러나 일반적인 무선 환경에서는 핸드오프나 비트오류 등 단시간 단절이 매우 흔한 일이지만 TCP는 이를 유선상의 혼잡 신호로 인식하여 전송 윈도우의 크기를 줄이고 불필요한 대기시간을 설정하는 등의 혼잡제어 정책을 수행하게 된다. 따라서 이러한 문제를 해결하기 위해 여러 계층에서 시도하는 노력이 있었으나 링크 상태를 파악하여 응용계층에서 자료 전송 여부를 미리 결정할 수 있다면 불필요한 전송을 막을 수 있다. Remote Method Invocation(RMI)는 대화형 응용 프로그램과 서비스를 쉽게 만들 수 있도록 해주는 Java 기반의 하부 구조로써, 응용계층과 전송계층의 중간에 위치하여 사용자의 자료를 전달하는 역할을 하므로 이를 수정하는 것이 가장 바람직하다. 이 논문에서는 무선 상황에 적절하게 적응하는 RMI를 위해 동작과정을 확장하여 구현한다.

  • Despite the fact that Daejeon has excellent technology infrastructures such as government-funded research institutes, Daedeok Innopolis, and KAIST, the infrastructure for initial investment and growth support for technological start-ups is not sufficient. In particular, the amount of venture capital supply in Daejeon is relatively low compared to other innovation infrastructures. The purpose of this study is to suggest the implications of the venture capital ecosystem in Daejeon area through the analysis of what evolution process has been undergoing and what improvements and complementary points are needed in the future. First, the role of public finance system should be strengthened in order to stimulate angel investment and private capital inflows to start-up companies. Second, in order to cultivate investment professionals in the region, it is necessary to grant local funds to local institutions, and to run investment expert training courses in universities. Third, cooperation between related agencies is needed to add accelerator functions to existing incubators and to foster new accelerators. Fourth, in order to expand the role of local governments, it is necessary to establish funds, to open innovation mindset of public officials, and to communicate effectively with the central government. Fifth, basic venture ecosystem infrastructures such as inflow of excellent manpower, prevention of technology deception, improvement of rechallenge environment should be expanded. Sixth, it is necessary to reorganize the step-by-step start-up financing policy of 'Establishment - Growth - Exit - Rechallenge'. This study is meaningful in that it has grasped the current status of venture start-up financial ecosystem in Daejeon, which is changing rapidly. In particular, it is different in that it identifies financial difficulties venture companies in Daejeon and finds ways to utilize existing financial ecosystem efficiently.

  • 네트워크의 광역화와 새로운 공격 유형의 발생으로 침입 탐지 시스템에서 새로운 시퀀스의 추가나 침입탐지 모델 구축의 수동적인 접근부분이 문제가 되고 있다. 특히 기존의 침입탐지 시스템들은 대량의 네트워크 하부구조를 가진 네트워크 정보를 수집 및 분석하는데 있어 각각 전담 시스템들이 담당하고 있다. 따라서 침입탐지 시스템에서 증가하는 많은 양의 감사데이터를 분석하여 다양한 공격 유형들에 대해서 능동적으로 대처할 수 있도록 하는 것이 필요하다. 최근, 침입 탐지 시스템에 데이터 마이닝 기법을 적용하여 능동적인 침입탐지시스템을 구축하고자 하는 연구들이 활발히 이루어지고 있다. 이 논문에서는 대량의 감사 데이터를 정확하고 효율적으로 분석하기 위한 마이닝 시스템을 설계하고 구현한다. 감사데이터는 트랜잭션데이터베이스와는 다른 특성을 가지는 데이터이므로 이를 고려한 마이닝 시스템을 설계하였다. 구현된 마이닝 시스템은 연관규칙 기법을 이용하여 감사데이터 속성간의 연관성을 탐사하고, 빈발 에피소드 기법을 적용하여 주어진 시간 내에서 상호 연관성 있게 발생한 이벤트들을 모음으로써 연속적인 시간간격 내에서 빈번하게 발생하는 사건들의 발견과 알려진 사건에서 시퀀스의 행동을 예측하거나 기술할 수 있는 규칙을 생성한 수 있다. 감사데이터의 마이닝 결과 생성된 규칙들은 능동적인 보안정책을 구축하는데 활용필 수 있다. 또한 데이터양의 감소로 침입 탐지시간을 최소화하는데도 기여한 것이다.

  • This study analyzes the development of technological infrastructure(TI) and technological infrastructure policy(TIP) to enhance the technological capabilities of small and mid-sized manufacturing enterprises(SMEs) in the U.S. and Korea in terms of the technological system(TS) concept, which is composed of technological infrastructure, industrial organization, and institutional infrastructure. In order to analyze the internal dynamics of the system, such as incentive mechanisms, the interaction among economic actors, and the policy implementation process, we compare the MEP(Manufacturing Extension Partnership) system of the U.S. and the Joong-Jin-Gong system of Korea. Among many similarities, contrasts, and insights from each country's effort to construct TI and TS, the main findings are as follows. (1) Both the MEP system and the Joong-Jin-Cong system are TI-led or government-led type TS. However, the nation-wide picture is different: in the U.S., most TSs including the MEP system., are classified as TI-led type; in Korea, many TI-assisted or private sector-led TSs have been developed since the early 1960s. (2) the MEP system, as a representative case of the U.S., is less stable than the Joong-Jin-Gong system of Korea in terms of financing and political cycle. (3) The MEP system is a more complex and cooperative network than the Joong-Jin-Gong system. NIST, as a critical mass, generates the system, bridges various institutions, and influences the development of the system by providing funding. (4) Regarding TI components, TSs in both countries focus on utilizing off-the-shelf technologies rather than advanced technologies. However, the direction of movement is different: in the U.S., TSs have come to emphasize existing technologies to counterbalance an innovation system that has been highly focused toward new technologies; in Korea, TSs have been moving from focusing on a higher diffusion rate of imported process technologies to stressing new technology development. (5) Personnel and staffing, embodying technological capability, is an important concern in both countries. But the human capital infrastructure of the U.S. system is more efficient and industry-oriented than that of the Korean system due to a more flexible labor market. (6) While the U.S. has a strong tradition of state and local autonomy in constructing TI and TS to fit SMEs's specific need, Korea has a centralized and bureaucratically-led policy implementation process.

  • This study attempts to analysis the roles of national laboratories in the context of regional innovation systems and the contribution to local economic development in the case of Taedok Science Park in Korea. It also tries comparative studies between Taedok Science Park and some European experiences. Recently the role of national laboratories as key innovation agents for regional development strategies is emphasized in European countries. In the similar context, national laboratories have explicit missions to assist in the formations of new firms and to support existing small and medium-sized enterprises in their localities. It is found that these functions are largely present and become more important in Taedok, but that the linkages between national laboratories and local firms are still weaker than some European countries. This study concludes that national laboratories in Korea should reinforce the industry-research linkages with local economic activities in the region to stimulate cooperation activities.

  • This study examines the case of living lab applied in the R&D initiatives for solving societal problems and challenges. It discusses how to use the living lab in national R&D projects. The analyzed cases are 'Develop portable fundus camera for eye disease screening test to resolve health inequalities' and 'Auto-sensing integrated system development in rural pedestrian crosswalk'. As a result of the analysis, both cases were designed as a user participatory R&D structure by utilizing living lab. In other words, living lab has operated as a system that evolves technology-products-services into an infrastructure. It can realize final demand specification, product, service improvement and demonstration through continuous interaction of end users. As a result of the case analysis, the following policy tasks can be derived. First, living lab is a new concept and it is in the early stage of implementation in Korea. Therefore, it is necessary to monitor and evaluate living lab experiments and build suitable models for Korean society by sharing cases and achievements. Second, the strategic niche management are necessary for the introduction of living lab. Third, living lab can be used as a tool to transform the existing technology acquisition centered innovation policy to the policy for customer needs and problem solving. Fourth, there is a need for flexibility and adaptability in strategy and system to correct errors that appear in the living lab processes.

  • This paper aims to explore the viability of a rural-industrial complex neighbouring in the metropolitan area and suggest policy implications for the restructuring of the rural industrial complex. In particular, the paper focuses on the location and management practices of the firms operating in the industrial complex. Research shows that the key elements of the viability of the rural industrial complex in Koryung-Gun are the geographical and relational proximities to the metropolitan city of Daegu and the decentralization of urban industries towards rural areas neighbouring in the large city as a result of the deterioration of location conditions in the large city. It is revealed that the major pull factors of location are 'availability of cheap industrial sites', 'agglomeration in a specialized industry' and 'proximity to major customers and suppliers' rather than 'availability of labour pool'. However, it shows that 'weak university-industry linkages' and 'insufficiency of cooperation culture' are the major limitations to attracting firms. In the context of pub1ic policy, the author argues that the restructuring of the rural industrial complex should be sought to promote social infrastructures centered on networks and learning rather than firm centered financial and tax incentives.

  • Recent modeling and simulation technology is being used in various fields. Especially in the field of military, Simulation-Based Acquisition (SBA) is recognized as a essential policy. To effectively carry out SBA, modeling and simulation techniques should be applied in the whole life-cycle for the weapon system development, and simulation architecture framework which provides easily reusable and interoperability is needed. Through reusability and interoperability, the costs of constructing the integrated collaborate environment for simulation based acquisition can be minimized. In this study, we define requirements, issues for enhancing reusability and interoperability, and propose simulation framework as a solution of the problem including structural design. Proposing simulation framework provides common functions for producing simulator as reusable units and easily changeable structure on user's purpose. In addition, we provide the result for applying simulation framework to our project.

  • Health promotion has more comprehensive approaches in recent years. Nevertheless we accept the concept of health promotion differently, we are agree on that community is the most important field in health promotion which includes population at the aspect of health policy, individual skill and, environment. And there are a number of different approaches to health promotion. In them, 'population approaches' and 'high -risk group approaches' has the most different characteristics. 'Population approaches' is equally important or more important than 'individual approaches' for maintaining and promoting population health. Almost part of this article contents is the summary of the guideline and population strategy of health promotion in Korea, 1999 - 2005. Community based health promotion program should be reinforced, integrated, comprehensive, collaborative through efficiently utilizing community resources. Recent new orientation of community health program is integrated health program, we can find this orientation at Ottawa charter 1986. Comprehensive approaches with the determinant factors for health are essential task. Physical activity is a key health determinant. The population-health approach suggests that educating people about physical activity is not enough. Individual behavior changes are important too, but need to be balanced with strategies for environmental change. Population strategy with physical activity for health promotion should be developed through improving social and physical supportive environment, linking and integrating community resources between public and private sectors in national, regional and local level. Continuous public education and social marketing should be provided through collaborating with community physical activity organization, facilities, work-places and school for increasing concern of all the people of community about physical activity. Governments, agencies and citizens should held and participate to building movement. And the strategy that various 'active for life' program should be developed, delivered, maintained and reinforced continuously. Basically, adequate and sufficient financing, developing human resources, policies and legislation would be provided and supported fully too. At last, research development and knowledge exchange are required domestically and internationally. In Korea, we had classified the category of strategic priority of physical activity programs by environmental support, life-course approach, high-risk group approach and disease group approach for physical activity program based on community health center. Community based core programs for physical activity that includes infrastructure building and establishment of supporting environment, community campaign, health promotion education and public service announcement, physical activity programs for elderly and obesity, exercise prescription program.
