The productivity of port labor in Pusan port is very low and the ratio of port accident is high in comparision with other advanced foreign ports. The aim of this paper is to find why the productivity in Pusan port is much lower than that of other countries in terms of port labor education systems. To obtain the objective of this study, the writers used 163 questionnaire for port labor in BCTOC, PECT and UTC for the survey of training method of cargo equipment handling. The result of this study shows as follows; (1) From the fact that ratio of labor who were trained by KPTI was 2.5%, we could say the public training system of port labor is not operated properly (2) As most of laborers are trained by the experienced associate, they do not recognize how the level of cargo handling equipment is set to increase the productivity. (3) In order that the port public training system plays a good role in port industry, a new license system should be introduced and an expert education system should be developed.

The export/import processing systems of the foreign advanced port use the integrated database to increase the productivity of the users involved in the port and logistics activities. However all the port and logistics related organizations in Korea such as container terminal, customs, ministry of maritime affairs and fisheries, etc. are using their own databases, so it is very inconvenient to the users to process their export/import affairs. It is necessary to develop the integrated database for the port and logistics affairs to provide the one stop service to the port and logistics related users. So we have investigated and analyzed the databases of port and logistics related organizations, and recognized the users' various needs of information. And then we have suggested the conceptual architecture of integrated database for port and logistics, and proposed the strategies for successful development of the integrated database in this paper.

자포니카 벼 내염성 품종육성을 위한 모본들의 조합능력을 아는 것은 교배친의 선정과 육종효율면에서 대단히 중요하다. 본 연구는 유묘기 내염성 관련형질에 대해 내염성 정도가 다른 9개 품종을 가지고, 이면 교배를 실시하여 모본 및 F1 에 대한 유묘기 내염성 검정을 통하여 조합능력을 평가할 목적으로 수행하였다. 유묘기 내염성 평가형질에 대한 일반조합능력 및 특수조합능력은 친품종간 및 F1 간에 고도로 유의한 차이가 있었으며, 특히 일반조합능력이 특수조합능력보다 크게 나타나서, 여기에는 상가적 유전자작용이 비상가적 유전자작용보다 훨씬 크게 관여하고 있음을 알 수 있었다. 각 모본들에 대한 일반조합능력은 Gaori, Namyang 7 그리고 Agami M1 같은 내염성 품종들이 지상부 건물중 및 뿌리 건물중 감소율에서 모두 다른 친품종들에 비하여 우수하였다
