The longitudinal structural members in way of upper deck of container carrier consist of very thick plates with high tensile strength and high grade, which are of high cost. And also these are the most effective longitudinal strength members. Therefore it is necessary to carefully design the concerned part to minimize the cost. The purpose of this study is to find optimum design of the concerned part in the aspect of cost. ES(Evolution Strategy) technology is applied in this study, and the method to get practically the result is invented. The minimum cost design considering steel materials and/or assembling man power is carried out for existing ships and the effect of the variation of thickness difference, material and labor cost on the result of optimum design is investigated.

The objective of this study was to propose the best methodology for estimating soil organic carbon stocks during environmental assessment for development projects. We compared three methodologies which were developed by Korea Environment Corporation(2010), Korea Forest Research Institute (2006), and Jin-Hyun Jung (1998). We found that the methodology developed by Jin-Hyun Jung (1998) shows the worst performance and the methodology of Korea Forest Research Institute (2006) does not reflect a variety of soil types and land use characteristics shown in development project plans. Therefore, we propose that the methodology developed by Korea Environment Corporation (2010) is the most reasonable one because it is internationally accepted and used for local governments to make the inventory of greenhouse gases as well as to set up its reduction strategy.
