Rotor disc (로터 디스크)는 중대형 유조선에서 유류를 하역하는 장치인 COPT (Cargo Oil Pump Turbine)의 터빈을 고속으로 회전시키는 핵심 부품이다. 이 rotor disc는 중심 shaft에 여러 개의 turbine을 원주상으로 배열하고 체결하여 제작한다. 현재의 제작 방법으로는 turbine blade를 배열하고 shroud 덮개로 연결하여 riveting 방식으로 체결한다. 이런 고전적인 방법은 blade pitch의 불균일은 물론 작업 시 오류로 인해 blade에 손상이 가는 경우가 있다. 이러한 단점을 해결하기 위해서는 조립식의 rotor disc를 설계하여 제작방식을 변경해야 한다. 설계뿐만 아니라 조립식의 disc가 구조적으로 안정한지를 평가해야 한다. 본 논문은 blade의 설계와 이를 조립하였을 때에 구조안전성을 평가하기 위해 구조 해석하여 그 안전성을 검증 한다.

Joint order and transportation system which can be used for the franchise business is considered. It is assumed that several agents exist on the same vehicle route and each agent has an EOQ inventory policy and the same order cycle. It is also assumed that transportation cost is proportional to the distance of farthest agent from the supplier. Various methods for rational and fair cost allocation such as line rule, AMEF, the Shapley value, nucleolus, and proportional method were researched and applied to the inventory transportation problem. The core is the basic condition for rational and fair cost allocation. Therefore, we examined if the solutions of various allocation methods are existed in the core through an example.

The base quality score recalibration (BQSR) is an important step in the variant calling from high-throughput sequence data. Motivated by the fact that BQSR necessarily requires a database of known variants such as the dbSNP, we present an extensive analysis on BQSR results for human and rice genome. We showed that the recalibration results depended on the size of the database. The more variants are there in the database, the larger averaged value of the recalibrated quality scores is obtained. This implies that the recalibrated quality score is lower than it should be when the number of variants in the database is not large enough. Based on the finding that the size of the database should play a crucial role in BQSR, we proposed a method to create a database when the size of a database is not large enough for BQSR results to be reliable. We demonstrated that, in the case of human, the database constructed by the proposed method generated almost the same results as the human dbSNP. In the case of rice, however, we showed that the proposed database is more reasonable than the rice dbSNP by illustrating how the proposed method is effective.
