본 연구에서는 웹서비스 기반 그리드 환경에서 효과적인 자원선택을 할 수 있는 자원 선택 프레임웍을 설계 구현하였다. 이 프레임웍을 활용하여, 어플리케이션이 요구하는 자원 명세와 자원 공급자의 자원공급 정책을 기술할 수 있도록 지원하고, 이틀 토대로 다양한 자원 선택 알고리즘을 개발할 수 있을 것으로 기대된다. 또한 본 연구에서 구현한 프로토타입 시스템을 소규모의 그리드 환경에 적용해 얻은 실험 결과를 통해, 그리드 상에서 어플리케이션의 성질을 고려한 자원 선택이 충분한 효과를 나타냄을 확인할 수 있었다.

In order to manage repair and maintenance efficiently in the mobile environment, the system structure to manage service as a policy and the policy description language are needed. This research defined the structure of PEP, which is the executioner of policy in the IETF policy framework, and proposed the policy description language which can be carried out under the PEP structure. The proposed policy description language derived demand matters based on documentary data and the characteristics of mobile and the policy information model was designed with the three stage approaches and was defined as policy description language. The three stage approaches are made up of the policy domain that decides the scope to which the policy applies, the policy rules which distinguish the kinds of policy application and control, and policy grammar which contextualizes the policy structure. In order to verify the efficiency of the policy description language, scenarios are defined with the policy description language and verified it by using policy tool and proved the expansive nature by comparing and analyzing other policy description language.

This paper presents GDOCF(Government Document Enterprise Architecture Framework) based on the direction of EA(Enterprise Architecture) framework to build GDOCEA. The construction of EA for GDOC offered various types of information technology Platform which advanced the interoperability between Government Information Systems. In addition, it insured the interoperability between the e-Government Initiatives and helped a consistent management for information resource. As a result, MOGAHA could support a policy decision and capital investment plan for information. Also, all the information needed for the operation and management of GDOC has been being referenced, shared and utilized as EA repository. Eventually Pilot EA would be a corner stone to build EA master plan considering all the information systems in MOGAHA.

최근 하천관리 정책은 단편적인 홍수방어뿐만 아니라 맑은 물을 안전하게 확보하고 건강한 생태계가 유지되는 하천으로 관리하는 방향에 주안점을 두고 있다. 그러나 치수 목적의 하천관리 기술에 비하여 하천환경관리를 위한 기술은 요소기술 개발 및 적용으로 산재되어 있어, 체계가 정립되지 못하고 실무 적용에서도 활용에 한계가 있는 실정이다. 따라서 본 연구에서는 치수, 이수, 하천환경 목적의 다차원 하천관리를 위하여 하천복원의 기술적 체계를 기술수준의 정도를 기준으로 단계별로 정립하였다. 첫 단계는 수문특성, 수리특성, 하상변동/유사특성, 생물/화학특성의 분석이다. 이 단계에서는 각 특성의 현황과 하천복원 방법에 따른 물리특성 변화를 분석하는 것이다. 다음 단계는 하천복원에 따른 정량적인 기대효과 분석이다. 수위저감 및 안정하도 확보, 수질개선, 생물서식처 효과분석 등이 수행된다. 마지막 단계는 하천복원 등의 관리계획에 의한 기대효과 전망이다. 사회경제적 가치, 생물종 다양성 확대가치 등이 분석항목에 포함된다. 각 단계에서는 계량 가능한 지표를 설정하여 계획의 성과를 비교한다. 제안된 다차원 하천복원 기술적 프레임웍을 통해 하천사업에 따른 물리, 생물, 사회, 경제 등 다양한 분야의 구조를 통합한 방법론을 제시함으로써 하도개선 위주의 획일적인 하천복원사업에 변화를 주고, 더 나아가 하천공간 복원 등 적극적인 하천복원사업이 활성화되길 기대한다.

Because of explosive increase of information, it spends a lot of time to trace and analysis research trends during total R&D process. It has rapidly evolved from R&D or process development within a specific domain of knowledge to R&D or process development through knowledge convergency. To accept such a paradigm, it is necessary to convert dissemination system from a separate, standalone, and fragmentary information to highly coupled fusion information. Although there are several studies on knowledge flows between science and technology or technology and industry, it is difficult to analyse and utilize quantitatively to establish policy of Science, Technology, and Industry. The reason is the lack of information resource to analyse knowledge flow from science to industry. This paper intends to develop framework of highly coupled linking system between patent and scientific paper to utilize R&D, S&T policy, and industry policy.

It is difficult to provide Web services on a mobile environment because of the intermittent disconnection of a wireless network and the frequent change of context information. To resolve this, Web services must be migrate to devices, which can provide services to users seamlessly. However, researches on hosting, migrating, and replicating Web services on mobile devices are still in an early stage. This paper presents a lightweight Web service framework and an efficient method for establishing a policy of migrating Web services. Based on the WS-Policy standard, the proposed method defines a policy schema, which provides constructs for describing various kinds of contextual information. Specifically, the schema is designed to be extensible enough for different service providers to use different vocabularies to describe their policies. To show the validity, the proposed method for establishing a migration policy has been applied to our mobile Web services framework, resulting in a seamless provisioning of services.

Although many studies have focused on the influences and outcomes of personal information leakage, few studies have investigated how the personal information leakage prevention behavior differs depending on internet user. This study attempts to supplement the existing studies' limitations with the use of risk perception attitude (RPA) framework. More specifically, this study tries to show internet user can be classified into four groups based on perceived risk of personal information leakage and efficacy beliefs of personal information protection, and to identify how the groups differ in terms of motivation, information seeking, and behaviors for privacy leakage prevention. Analysis on survey data from 276 internet users reveals that the users can be classified into responsive, avoidance, proactive, indifference groups. Furthermore, there are differences between groups in terms of motivation, information seeking, and behaviors for personal information leakage prevention. This study contributes to expand existing literature by providing tailored guidelines for implementation of personal information protection strategies and policy.

전통적으로 대기업구조에 의존해 왔던 우리 나라 경제가 IMF외환 위기 이후 재벌의 구조조정, 정부의 벤춰산업 육성정책에 힘입어 벤춰중심의 산업으로 신속히 재편되어가고 있다. 디자인의 경우에 있어서도 대기업의 사내 디자인 부서 (In-House desgin team)중심에서 벗어나 소규모의 독립 디자인 전문회사의 수가 급속히 증가하고 있는 실정이다. (중략)

The National IT Plan is formulated every 5 years in Korea. Each ministry formulates its own annual IT plans and budgets based on the National IT Plan. Presidential agenda, in addition to the Ministry plan usually come in the budgetary process. A budget view and an IT view are not always aligned consistently in the budgetary process. For more consensus and less conflict between the finance ministry and the IT ministry, it would be useful to have a common framework to examine and review the many IT plans submitted by many ministries. We offer an EA-based framework that considers various views and classifications on IT plans. This framework would make the National IT Planning more efficient and effective.

This paper aims to analyze the change of dominion in Russian automotive market and Korea port to export cars to the Russia. First, we provide the current market structure and growth potentials of Russian automotive industry by using literature reviews and data survey. Next, we analyze the current situation to export cars through the Korean seaports using the BCG (Boston Consulting Group)'s matrix method. The analysis shows that the Russian car market has growth potential. The result of expectation of Russian major car export's port within 3~5 years since the year 2013 shows that the Pohang Port will maintain current market share because it has higher market share and growth potential. On the contrary, the Guangyang Port, Busan Port, and Ulsan Port will lose the market share because of the low growth potential. Also, the Incheon Port will become the cash cow market because it has more than 10 percent market share and higher growth potential. To increase the car export volume of ports to Russian market, this paper proposes that we should provide a differentiated service to Russian port based on the analysis of domestic or foreign car export logistics structure and flow. For further study, EA-based framework should be applied for efficient and effective policies.
