국가에서는 수해예방 및 주민들의 삶의 질 향상을 위해 다양한 하천사업을 수행한다. 국토교통부의 경우 매년 막대한 예산을 투입하여 하천정비 및 재해복구사업 등을 추진 중에 있으나, 체계적인 공사관리와 산출물의 전산화를 위한 시스템은 부재한 실정이다. 현재 건설사업정보시스템(건설CALS)을 통해 하천공사에 관한 정보를 확인할 수 있으나 총 공사비, 참여업체 등 기본적인 정보만을 제공하고 있으며, 공정관리 및 예산정보에 관한 상세한 내역을 확인 및 관리할 수 있는 기능은 부재하다. 이러한 문제를 해결하고자 본 연구에서는 하천사업(공사)관리시스템의 필요성을 제시함과 동시에 우선적으로 하천사업 공종 표준화를 수행하고자 한다. 현재 건설공사표준품셈을 통해 건설공사의 공종을 확인할 수 있으나 '제2장 하천공사' 내에는 사석, 돌망태, 하천호안공에 관한 정보만을 담고 있다. 하천공사 공종 표준화를 진행하게 될 경우 공종별 공사 세부정보에 대한 관리가 가능해지며, 현재 하천을 관리 중인 국토교통부, 지방국토관리청 및 지자체 등 하천사업을 수행 중인 기관의 시스템 활용도를 제고할 수 있다. 하천사업 공종표준화를 위해 우선적으로 현재 건설공사표준품셈, 도로대장 전산화 입력지침 등기 수립된 지침 및 기준을 통해 건설토목공사 시의 공종을 조사·분석한 후, 하천공사 준공보고서 및 감리보고서 등 공사 관련 자료를 활용하여 하천공사에 주로 수행되는 공사들에 관한 종류를 도출하였다. 이후 건설토목공사 공종과의 비교·분석을 통해 하천공사에서 주로 수행되는 공종을 도출·표준화하는 작업을 진행하였다. 본 연구에서 제시한 하천사업 공종의 경우 향후 하천사업(공사)관리시스템 개발에 활용이 가능하며, 하천공사 관리의 효율성을 극대화할 수 있다.

This research focuses on the issue of seismic retrofit prioritization based on the Caltrans' highway network serving Los Angeles and Orange counties. Retrofit prioritization is one of most important problems in earthquake engineering, and it is a problem that most decision makers face in the process of resource allocation. This study demonstrates the methods of prioritized resource allocation in the process of retrofitting a regional highway network. For the criteria of a retrofit ranking, seismic vulnerability and the importance of network link are first introduced. Subsequently, link-based seismic retrofit cases are simulated, investigating the effects of the seismic retrofit in terms of seismic performance, such as driver's delay. In this study, probabilistic scenario earthquakes are used to perform a probabilistic seismic risk analysis. The results show that the retrofit prioritization can be differently defined and ranked depending on the stakeholders. This study provides general guidelines for prioritization strategy for the effective retrofitting of a highway network system.

To support multimedia applications such as a multimedia communication systems and multimedia broadcasting, an operating system need to predict their timing-constraints. So, In this real-time systems, we must solve the priority inversion problem that may make the behavior of unpredictable systems and need a real-time server model that provides a better preemptability and minimizes a system overhead. In current real-time systems, the single thread server model, the worker model and the dynamic server model are being used for synchronization but they cannot propose an effective structure for managing shared resources. In this paper, the priority inheritance protocol is used to solve the priority inversion problem and the hybrid prioritized worker model is proposed, which can provide a more effective structure and a faster response time minimizing a system overhead. The hybrid prioritized worker model is to combine the static and the dynamic prioritized worker model, and have a better performance than other models in response time which is an important factor in a real-time system.

This study was conducted to find out basic facts on educational resources in Korea and see how educators have managed their tasks without educational resource archives. The research had the following steps: 1) finding out how the current state of primary and secondary education resources is managed and type of educational resources via Web search and literature review, 2) conducting a survey to determine archiving priorities according to the value of resources to the users, and 3) engaging in a discussion with experts on merits of establishing an educational resource archive system. Due to sporadic management and restricted use of educational resources produced in Korea, the primary and secondary education resources are not easily available to the public even though the public and private sectors produce significant amount of resources. The survey result on preferred educational resource types for archiving showed the following top three: 1) actual case studies conducted in the field, 2) curriculum related resources, and 3) various textbooks adopted. Considering the value of educational resources and the necessity of archiving agencies, the experts recommended to set up a national archiving system of educational resources. This study hopes to raise awareness of the need to set up educational resource archives as a start.

This study was conducted to derive a priority of investment in educational facilities by collecting and analyzing investment records from elementary, middle, and high schools in Chung Nam area. In addition, the AHP survey and analysis were performed in order to draw the priority item in the educational facility improvement. Students, parents, teachers and a educational facility managers from those schools provided their opinions and data for the AHP study. As a result of the study, the actual investment-cost and a lack of educational facilities were found. A priority item based on the above study was derived which can be used to increase user's satisfaction in the educational facilities. The result of this study can be used as a basis to improve the environment of the educational facilities.
