네트워크에서 보안 기능을 전개하는데 있어 정책 기반 전개 방법이 널리 사용되고 있다. 본 논문에서는 정책 기반 보안 기능 전개에 있어 정책을 설정하고 검증하기 위한 프레임을 제시한다 정책 기반 기능 전개에 있어 중요하고도 어려운 문제는 설정한 정책의 정확성(correctness)과 완전성(completeness)을 검증하는 것이지만 이에 관한 기존의 방법은 주로 경험이나 혹은 감시에 의한 끊임없는 정책 갱신이다. 본 연구에서는 기존의 제안된 여러 보안 모델들을 검토해보고 이 모델들로부터 공통적으로 적용할 수 있는 정책의 정확성과 완전성을 위한 제어 프레임을 설계한다.

인터넷의 급성장은 웹서버의 요청율을 급격하게 증가시키고 심각한 정체를 일으키고 있다. 이를 해결하기 위하여 클라이언트의 요청을 분산된 여러 서버들에게로 전달시키는 방법이 많이 사용되고 있다. 이 방법은 웹서버의 처리량을 향상시키고 확장성과 가용성을 제공하지만 서버들의 부하를 균등하게 하는 방법이 필요하게 된다. 이러한 부하 균등을 위해 크게 DNS(Domain Name Server)를 활용한 정책과 IP 단계에서 분배기(Dispatcher)를 사용한 정책이 제안되었다. 본 논문에서는 전자와 후자의 단점을 보완하고 성능을 향상시킨 다중 분배기를 제안하고 실험하였다.

최근 인터넷의 급성장을 기반으로 유비쿼터스 환경이 도래하면서 다양한 환경요소를 가진 자원들이 네트 워크 상에 공존하다. 이러한 환경에서 적절한 보안 서비스를 제공하기 위해서는 자원의 환경정보를 제공하는 컨텍스트(Context)를 기반으로 적절한 보안정책을 결정하는 것이 필요하다. 본 논문에서는 유비쿼터스 환경에서 제공되는 상황정보를 통해 사용자의 선호도, 디바이스의 성능, 서비스의 가치 등 다양한 자원의 환경요소를 획득하여 MAUT와 간결한 휴리스틱스를 이용하여 자원에 적절한 보안 등급을 적응적으로 결정하는 알고리즘을 제안하고, 이를 바탕으로 유비쿼터스 환경에 적합한 보안정책 관리 모델을 제안한다.

Because of increasing the notebook computer and PDA, users' requirement with respect to mobility is growing more and more. However, current IP protocol is not changed IP address and can not deliver IP packets on new location of host in case moving another network. To solve this problem, the IETF has proposed mobile IP. Today users want to be provided suitable QoS in the internet since demand of services is variety. The policy-based network management is method which can solve various problems of QoS, security, and complication of management in IP networks. This paper presents the network topology constitution, operation procedure and architecture of policy-based network management for providing internet DiffServ on mobile IP environment. In this paper we propose policy classes of policy-based DiffServ network management on mobile environment and create policy scenarios using the proposed policy description language to represent the policy classes. Finally, we implemented a policy-based DiffServ network management system on mobile IP environment.

This study aimed to present a policy direction that could preemptively respond to urban development by analyzing past trends and predicting future changes in urban logistics in South Korea. In particular, the scope of the study was centered on changes in the national and regional logistics master plans presented in a framework that acted on logistics policy. So, the study examined the policy changes related to urban logistics from the past to the present based on the national logistics master plan and identified a national policy base to respond to the expected changes in the logistics environment in the future. Moreover, by combining this base with the contents of the urban logistics master plan of Seoul, we proposed a logistics policy that should be continued or newly added to the urban logistics master plan. Policy proposals were also presented by dividing the future logistics environment changes into policy, social, and technological changes. In particular, the policies were proposed in urban planning (10 policies), transportation planning and ITS (8 policies), logistics technology and ITS (6 policies), and laws and systems (8 policies). Regarding policy continuity, 15 policies needed to be continued, and 17 policies were to be introduced later.

This study has been motivated by the awareness that studies on science and technology policy do not have an independent academic identity in Korea as of 2017. This research has been analyzed 19 books that have covered science and technology policy published in Korea and explored whether those have a definition of discipline and core research scope which are the key elements forming academic paradigm. As a result, this study concludes provisionally that studies on science and technology policy in Korea are still at a stage that has not yet formed a paradigm. Therefore, this work newly proposes the definition of discipline and research scope necessary to complete the paradigm of studies on science and technology policy based on this conclusion. This paper has firstly defined that studies on science and technology policy are the policy-oriented discipline. It is (1) promoting the development of science and technology itself by studying and analyzing the various phenomena of politics, economy, society, and culture related to science and technology activities as well as science and technology and (2) makes the national and public sector improve problem-solving competence using science and technology. This work also proposes a research scope consisting of four research areas such as (1) policy process of science and technology, (2) public management of science and technology, (3) R&D management and (4) technology innovation. 'Policy process of science and technology' and 'public management of science and technology' among four research areas are the new research ones reflecting the definition of studies on science and technology policy proposed in this paper. Additionally 'R&D management' and 'technology innovation' are the traditional research areas which have also included existing researches regarding science and technology policy.

This paper proposes the architecture and the methods of security network management for auto-configuration of security systems by extending the existing policy-based network management architecture. The architecture and the methods proposed in this paper enable a security management sewer to automatically decide the best-suited security policy to apply to a security system and the most effective and efficient security system to perform security policy rule, based on the role and capability information of security systems and the role and time information of security policy. For integrated control of network system and security system, this paper also proposes SNMP protocol based security network topology map generator. To show the excellence of the proposed architecture and methods, we simulate and evaluate the automatic response against attacks.

In 3G networks interworking with external IP-based networks, provision of end-to-end QoS to packet-based services is a critical issue. In this paper, we propose DiffServ-aware Multiple Protocol Label Switching(MPLS) as a new policy enforcement means. With the adoption of the proposed DiffServ-aware MPLS, it is feasible to provide differentiated QoS provision with the help of DiffServ as well as to improve network utilization by using multiple paths based on MPLS. We verify the effectiveness of our proposed policy enforcement means through a simulation in which realtime traffic and non-realtime traffic are served together.

본 연구는 정보통신 산업 클러스터의 사례분석을 통해 제조업과 비교.분석하여 정책적 방향을 제안하고자 한다. 국내외 정보통신 산업 클러스터의 사례로 미국의 실리콘밸리, 일본의 테크노폴리스, 중국의 중관촌, 스웨덴의 시스 타와 국내의 대덕 밸리를 중심으로 특성을 도출하고자 한다. 산업 클러스터는 마이클 포터의 연구를 시작으로 하여 OECD 에서 국가혁신체제의 주요 주제로 제안하면서 국가 경쟁력의 핵심으로 등장하게 된다. 정보통신의 발달은 지역에 기반한 글로벌 경쟁력을 가진 산업 클러스터에 대한 체계적인 연구와 이에 대한 정책개발의 필요성이 증대되고 있다. 정보통신 산업 제품의 특성상 기술혁신 속도가 빠르고 제품의 라이플 사이클이 제조업 제품에 비해 짧은 특징을 지니고 있어, 투자에 대한 위험 (risk)이 발생한다. 또한 지식창조산업으로서 생산위주의 제조업과는 다른 지리적, 공간적 특성에 차이가 있으며, 고급 인력기술자의 활용도가 높아 안정적인 환경이 요구된다. 따라서 통신, 교통 등의 물리적인 기반시설뿐만 아니라 정보통신 관련 업체간 연계와 독특한 사회.문화적인 분위기 등이 어울려져 있음을 살펴볼 수 있다. 이러한 정보통신 산업 클러스터의 특성을 통해 본 연구는 경제의 신 성장동력 중에 하나인 정보 통신산업의 경쟁력을 높이고 세계적 수출산업으로 육성, 정보통신 중심지로서의 역할 수행 및 동북아 경제 중심 실현을 위해 정책적인 제안을 한다.
