계속되는 도시 개발붐은 유역내 불투수지역을 증가시켜 첨두홍수유출량이 늘어나게 되었고, 도시지역 저지대에서 침수피해가 자주 그리고 크게 발생하게 되었다. 본 연구에서는 홍수침수피해를 최소화 하기 위하여 빗물펌프장의 과학적인 운영바안을 제시하였다. 첫째, 연구대상유역에 대하여 기왕의 강우사상에 맞는 도시 홍수유출모형으로 ILLUDAS 모형을 선정하였다. 둘째, ILLUDAS모형으로 재현기간별 강우사상에 대한 유출수문곡선을 모의한 후 강우지속기간에 따른 펌프

In this paper, the basic planning for the creation of consolidated agricultural institutions of Choongcheongnam -Do and its management schemes were established. These institutions, including rural development office, farmers'training institution, original seeding field of farm crops, agriculturial information center, packing design center, agricultural machinery repair center, agricultural scientific conference hall, agricultural museum, agricultural park, farmers'hall and event plaza, are planned to be created. The required area for the site is 1,246,781 m2. 281-22 Jongkyung-Ri, Sinam-Myun, Yesan-Gun, Choongcheongnam-Do and its surroundings is a proper site for the creation of'consolidated agricultural institution because the actual conditions of the soil, traffic network, irrigation and drainage, tourist routes and human resources are very good. The layout of the facilities that would comprise an agricultural institution was organized in consideration of the functions and roles of each facility and the relationships among facilities in this consolidated agricultural institution. It is desirable that the headquaters of consolidated agricultural institution oversees the management department, the planning . administration . information department, the rural development office, the farmers'training institution, the original seeding field of farm crops and the agricultural park.

Since the middle of 1950's, containerization has been rapidly spread over the world in virtue of great merits providing to interensts, and the fundamental changes in port management and prot operations are resulted. As the container terminal is a complex system which is consisted of various subsystems, the treatment for improving the productivity is required in a comprehensive fashion, both in each of its parts and as an integrated system. This paper aims to make an intensive analysis of the Busan Container Terminal system, especially focusing on its subsystems such as ship operation system, storage system and transfer system. First of all, the intrinsic capacity of various subsystems is calculated and it is checked whether the current operation is being performed effectively through the formal analysis. Secondly, the suggestion is presented to improve the operation by considering the throughput that the port of Busan will have to accept in the near future. The results are as follows; 1) As the inefficiency is due to the imbalance between various subsystems at Busan terminal, transfer equipment level must be up to 31% for straddle carrier and 67% transfer crane above all. 2) The yard capacity must be increased by reducing the free dwell time of containers in order to accept the traffic volume smoothly in the near future. 3) The better way to reduce the port congestion is to change berthing rule from the FIFP to the Pre-allocated system by considering the ship arrival pattern.
