According to the development of information & web technology and the amount of information increases, there have been numerous problems exposed. Although, software engineers try to overcome the limitations by using software agent and web service, there hasn't been satisfactory result in the paradigm of current software agent being a provider to the user's demand. Moreover, the latest configuration of software development is based on CBD (Component Based Development). However, to construct new component using CBD costs great deal of expenses and therefore, a new model which can acquirecomponent information on the web promptly and accurately with low expenses is required. In this paper, the repository management system which acquires and manages on the Semantic web is designed and compare them to the existing component repository management and present its analysis result. In addition, to overcome the limitations of existing component repository system; low accuracy of search result, restrictive search vocabulary and faulty information, the specific plan is presented to perform a knowledge search for the component.

In the knowledge-based economy, firms are increasingly exploiting their intellectual properties, especially patents. However, firms usually fail to commercialize all of their patents and some of them are not used even for strategic purposes. Therefore managing sleeping patents constitutes one important aspect of firms' overall patent strategies. This paper considers market uncertainty, technology uncertainty and strategic uncertainty as the reasons for sleeping patents. We analyze how firms' patent-related activities can reduce sleeping patent ratios. The firms' activities examined in here are patent audit, preliminary evaluation, prior art and cooperation. Noticing the prevalence of sleeping patents, this paper contributes by providing insights into how firm's activities affect the sleeping patent ratios. Insights for practitioners and policy makers have been provided from the empirical results.

In this study, It developed a program to carry out the training courses for NCS based medical information management tasks and to can understand the practical working knowledge of learners. This program is an educational program that can generate medical information by analyzing data of medical records after generating and storing data of medical records. Because the contents of the medical records vary and there are quantitative differences in the medical records, the contents of the medical records can be summarized and stored in the discharge analysis program for the standard of educational data. The medical terminology DB, medical terminology related DB, medical care related DB by the NCS ability unit element can be constructed and managed using the program. The following are the contents that can be learned through operation of the program. first, it's can understand Medical information DB management regulations through understanding sturucture of database. Second, it can understand the structure and function of the diagnostic code and medical practice code that are input to the discharge analysis program. The diagnostic codes and medical practice codes entered in the discharge analysis program can be searched and analyzed by each fields. Third, It can be advance medical information management ability by inputting and extracting data and generating medical information. In this study, It developed program that Students can be obtained Knowledge of medical information management and improved management competency by generate and analyze medical record data using discharge analysis program.

Estuaries have been used competitively and exploited for the past decades in Korea. To preserve the environment of the estuaries from the integrated perspective, new policies have started to change such exploitative development in 2000s. Due to the poor knowledge-base, however, there has been a lack of support system which enables to execute such policies effectively. The present study was conducted to figure out the limits of the estuarine management research projects in Korea, which is being performed to overcome these limitations. It was studied through Gap Analysis between domestic and foreign advanced practices as well as Analytical Hierarchy Process on expert survey in terms of the three aspects: how well the estuarine management research projects in Korea meets the demands of policy making and administration; raises the awareness of citizens about the merit of environmental preservation; and establishes knowledge-based support system. This project turned out to reflect adequately the development of programs for building estuarine management systems. But consideration of other ministries was relatively scarce. But the contents which directly support community-based activities and educational programs to improve citizens' awareness were judged to be insufficient. According to the results of Gap Analysis, research about the structure and function of estuarine ecosystems, which can support to develop policy alternatives in detail, was relatively more necessary. Therefore, to support estuarine policy management effectively, the development of a realistic plan, which can overcome fundamental issues inherent in the Korean environmental management system and the limitation of the estuarine management research projects in Korea itself, is needed.

본 논문에서는 블루투스 4.0(BLE) 기반의 비콘을 이용하여, 공항에서 물건을 찾을 때, 물건(가방)에 비콘을 장착하고 비콘의 신호를 받아 알림(Notification)을 주는 System으로써, 사용자의 편리성을 위하여 안드로이드 4.3이상 버전의 스마트 폰 Application으로 개발하였다. 스마트 폰과 비콘 사이에는 블루투스를 기술을 이용하여 통신하며, 비콘은 신호를 송신, 스마트 폰에서는 수신한다. 이러한 기능으로 Estimote사의 공개된 Software Development Kit(이하 SDK)를 바탕으로 개발을 진행하였다. SDK의 대표적인 기능으로 비콘의 정보와 연결 상태를 관리하는 객체, 그리고 Listener를 통해 범위 내 비콘을 탐색하는 기능을 정의할 수 있다. 또한 User Interface를 고려하여 사용자의 편이성과 접근성에 중점을 두어, 화면 구성에 많은 노력을 기울였다. 따라서 사용자의 배경지식, 연령대를 고려하더라도 쉽게 이용이 가능하도록 개발하였다.

최근 첨단 정보기술의 발전과 함께 지식정보사회로 전환되면서 전자상거래 분야가 빠르게 성장하고 있다. 전자상거래는 거래를 통해서 많은 개인정보를 수집, 관리 및 생성하게 되는데 일단 수집된 개인정보는 개인정보 주체의 꾸준한 갱신이 없다면 개인정보에 대한 기본 요구사항이자 개인정보 보호법에서 개인정보 주체의 의무사항인 최신성과 정확성이 결여된 상태가 된다. 따라서 이 논문에서는 최신성과 정확성의 결여로 발생되는 정확한 서비스와 사용목적 및 용도 변경시 동의를 받을 수 없는 문제, 수집된 개인정보를 주체는 어느 사이트에서 사용되고 있는지 알지 못하는 문제를 해결하기 위해 전자상거래에 사용되는 개인정보를 가변적 개인정보와 불변적 개인정보로 분류하고, 이를 기반으로 각 전자상거래 사이트들이 수집한 가변적 개인정보를 통합적으로 관리해 주는 방식의 최신성과 정확성을 충족시킬수 있는 통합 모델(Privacy Synchronization Unification Model)을 제안한다.

선박 운항시 운항소요인원을 최소화하기 위해서는 선박의 자동화 및 지능화가 필요하다. 특히 선박의 지능화된 운항을 위해서는 항해전문가의 지식을 저장, 관리하여 그것을 기반으로 항해전문가의 임무를 대신 수행하는 지능형 항해시스템(intelligent navigation system)이 요구된다. 지능형 항해시스템은 GPS, 전자해도, 항로계획, 항로감시, 항로관리, 경로계획, 경로감시, 경로관리, 유도, 제어 등의 기능으로 구성된다. 본 논문에서는 지능형 항해시스템의 자동화된 항로계획을 위해 폴리선기능을 응용한 항로계획(RPAP, Route Planning Applying the Poly-line)기법을 제안한다. 제안된 기법은 대표적 항로계획 기법인 $A^{*}$탐색기법과 비교 평가하여 그 효용성을 증명한다.
