본 연구에서는 포항시 양덕정수장에 tracer test를 이용한 pilot plant를 설치하여 기존 플록형성지에 대한 문제점을 도출하였다. 또한 플록형성지 각단 유출부의 단면을 여러 가지 형태로 변경시키면서 수리학적 평가를 실시하였고, 그 결과 플록형성지의 각단 유출부에 대한 최적 개량단면을 제시하였고, plant에 적용하여 현재 운전중에 있다. 또한 입자의 크기별 개수를 측정할 수 있는 particle counter를 이용하여 플록형성지 개량후의 효

In order to deal with the increase of container cargo traffic volume more effectively, the ministry of maritime affairs & fisheries has a long-term plan to develop Gaduk Island. According to the plan, the New Port will handle 4,600,00TEUs annually. The completion of the project will enable the port of Busan to perform as a hub port in the Asia Pacific era of the year 2000 with sufficient port facilities, and this will lead to a new era of oceanic Korea. With the advent of the Pacific Rim Era of the year 2000, Busan metropolis has set a strategic development plan to establish the area as the center of logistics in the noreast Asian region as well as to become the stronghold of economic activity in Korea's southeast region. To this end, industries that will open the doors to a marine era and a new industrial complex focused on logistics are planned in the West Busan area where Gimhae International Airport and the Busan New Port meet. This paper aims to find out the functional relation and complement between the Busan New Port Distri-Park handing container cargo traffic volume and the West Busan Logistics Pa가 handling an air cargo and railroad goods. Especially, paper aims to suggest the West Busan Logistics Park as the efficient management of the container cargo traffic volume due to the Development Plan of the Busan New Port.

In this paper, an improved high efficiency gantry crane for container transportation is designed. The basic concept of the designed crane can be used with modification of the classical gantry crane instead of changing lots of them. This crane can reduce the cycle time more than the classical gantry carne. The high efficiency gantry crane can improve the productivity of the container transportation job because of reducing cycle time. The loading and unloading capability are compared with classical crane. The result show that show that the proposed crane has better performances than classical type.
