World is experiencing abnormal weather caused by urbanization and industrialization increasing greenhouse gas and one of these phenomenon domestically happening is flood and drought. The increase of green-house gases is due to urbanization and industrialization acceleration which are causing abnormal climate changes such as the El Nino and a La Nina phenomenon. It is expected that there will be many difficulties in water management, especially considering the topography and seasonal circumstances in Korea. Unlike in the past, a variety of water conservation initiatives have been undertaken like the river-management flow and water capacity expansion projects. To meet the increasing demand for water resources, new environmentally-friendly small and medium-sized dams have been built. Therefore, the development of a new paradigm for water resources management is essential. This study shows that additional security is needed for potential water resources through diversion tunnels and is very important to consider for future water supplies and situations. Using RCP 6.0 and RCP 8.5 in representative concentration pathway climate change scenario, specific hydrologic data of study basin was produced to analyze past observed basin rainfall tendency which showed both scenario 5%~9% range increase in rainfall. Through sensitivity analysis using objective function, population in highest goodness was 1000 and cross rate was 80%. In conclusion, it is expected that the results from this study will help to make long-term and stable water supply plans by using the potential water resource evaluation model which was applied in this study.

The appearance of web technology has accelerated a role of the development of the multimedia technology, the computer communication technology and the multimedia application contents. And serveral researches of WBI (Web-based Instruction) system have combined the technology of the digital library and LOD. Recently WBI (Web-based Instruction) model which is based on web has been proposed in the part of the new activity model of teaching-learning. And the demand of the customized coursewares which is required from the learners is increased, the needs of the efficient and automated education agents in the web-based instruction are recognized. But many education systems that had been studied recently did not service fluently the courses which learners had been wanting and could not provide the way for the learners to study the learning weakness which is observed in the continuous feedback of the course. In this paper we propose "Design of Multi-agent System for Course Scheduling of Learner-oriented using Weakness Analysis Algorithm". First proposed system monitors learner's behaviors constantly, evaluates them, and calculates his accomplishment. From this accomplishment the multi-agent schedules the suitable course for the learner. And the learner achieves a active and complete learning from the repeated and suitable course.le course.

Using a multiproduct translog cost function model, this paper examines the existence or absence of scale and scope economies in Seoul's urban bus industry. The Paper then conceptualizes that the bus firm produces three outputs (city, seat and local bus-kilometers) using low input factors(labor, capital, fuel and maintenance). Using 1996 annual observations for 81 Seoul's bus firms, the equation system consisting of a cost function and three input share equations is estimated with the nonlinear iterative Zellner method. The findings show that the cost function corresponding to a non-homothetic production technology with separability between local bus outputs and inputs adequately represents the structure of cost for Seoul's bus firms, and that the demand lot all input factors is quite inelastic with respect to their own price. On the other hand, nearly all firms experience mild overall economies or scale, but rather marked product-specific economies of scale with respect to all the three outputs. In addition, there appear to be substantial economies or scope associated with the joint production of city and seat bus services, while considerable diseconomies of scope associated with that of city and local bus services. These results indicate that the merger of smaller firms into larger firms with a fleet of approximately 200 buses would result in more cost-efficient bus services.

전국에 산재한 수위관측지점의 관측개시 이후의 모든 홍수위 자료를 구성하고 주요 지점의 개별 홍수사상에 대한 단위도를 유도하여 지점별 대표단위도를 작성하였다. 또한 유도된 대표단위도를 이용하여 미계측 지점에 대한 단위도와 첨두홍수량을 추정하였다. 연구 결과를 요약하면 다음과 같다. 1991년과 1992년에 이어서 1993년에도 홍수위자료의 수집과 정리에 역점을 두어 관업을 수행하였으며 조선하천조사서, 조선하천조사연보, 한국수문조사연보 등의 각종 문헌에 수록되어 있는 주요 홍수사상의 수문곡선을 판독하여 전국 220개의 수위관측지점에 대하여 총 5,735개 사상의 홍수위 자료를 구축하였으며 이를 자료집으로 구성하였다. 홍수사상에 대한 단위도를 유도하기 위하여 시우량자료는 기상청 자료를 중심으로 구성하였으며 효율적이고 안정적인 능형회귀방법을 이용한 단위도 유도 방법을 적용하여 사용자가 화면을 통해서 홍수사상과 유도된 1mm-1hr 단위도를 보고 적합한 단위도를 선택할 수 있도록 단위도 유도 프로그램을 개발하였다. 대부분의 홍수사상이 지정홍수위 이상인 범위만이 정리되었는데 지정홍수위 이하의 부분은 일수위로부터 읽은 값을 참고로 하고 대수보간을 하여 자료를 구성하도록 하였다. 개발된 단위도 유도 프로그램을 사용하여 지점별 홍수사상별로 단위도를 유도하여 유역별로 총 65개 지점에 대하여 952개의 단위도를 유도하였는데 한강 유역은 16개 지점에서 263개의 단위도를 유도하였고 낙동강 유역은 28개 지점에 460개 단위도를, 금강 유역은 7개 지점 82개 단위도를, 영산강 유역은 7개 지점에서 88개 단위도를, 섬진강 유역은 7개 지점에서 59개의 단위도를 유도하였다. 유도된 단위도들을 지점별로 평균하고, 이를 참고로 하여 Nash 모형을 이용한 지점별 대표단위도를 유도하여 정리하였다. 또한 유도된 대표단위도를 유역에 따라서 지점별로 비교하여 상하류간의 관계를 분석하였으며 신뢰할만한 결과로 판단되었다. 유도된 대표단위도의 첨두유량 및 첨두시간을 유역면적 등과 비교하여 그 관계를 검토하였다. 유역면적과 첨두유량 및 유역면적과 첨두시간의 관계는 비교적 일정한 경향을 보여주었으며 이를 이용하여 미계측 유역의 1mm-1hr 단위도를 추정하였다. 2년 빈도의 설계강우량에 대해서 유역면적이 50, 100, 1,000, 10,000, 20,000$\textrm{km}^2$인 경우 첨두홍수를 추정하였으며 유출률을 0.9로 할 때 4장에서 분석, 제시된 지점별 평균연최대홍수와 비슷한 값을 보여주었다. 따라서 미계측 유역에서는 설계강우량만 주어진다면 본 연구에서 추정된 미계측 유역의 단위도 추정 방법을 이용하여 첨두홍수를 추정할 수 있을 것으로 판단된다. 본 연구의 단위도 유도 대상 지점은 전국의 수위관측지점이었으나 5대강을 제외한 기타 수계에 있어서는 수위자료뿐만 아니라 유량측정성과도 미비하여 단위도 유도를 하지 못하였다. 또한 유역면적 500$\textrm{km}^2$ 이하에서는 홍수위 자료는 있어도 유량측정성과가 없는 지점이 많았고 육량측정성과가 수 회에 불과한 지점이 대부분이었기 때문에 단위도를 유도할 수 없었다. 따라서 분석된 결과를 소유역으로 연장하는 것은 다소 무리가 따르며 대략 어느 정도가 될 것이라는 참고자료로 이용하는 것이 바람직하다고 본다. 현재의 여건에서는 소유역의 유량측정성과를 확충하는 일이 급선무일 것이다. 유역면적이 작은 수위 관측 지점에 대한 지속적인 유량측정이 절실히 요구된다.
