The transducers used in active sonar on surface ships are packed in a specific geometry in the array drum in order to meet the requirements such as the source level, directional beam pattern, etc. This paper describes the acoustic characteristics of the cylindrical array which is based on a 64 vertical staves arrangement, each stave composed 5 independent transducers. Firstly, the single transducer on the rigid baffle in the water is analyzed with the Finite Element Method. From the result of the FE analysis nodal velocities on the radiation surface is calculated and used with the boundary conditions of the transducers mounted on the array drum. Then the acoustic pressure is calculated in the field points using the Boundary Element Method and the other acoustic informations, the source level, beam pattern, near field and far-field distance, were acquired.

In this study, we investigated the effects of cooperative learning by the levels of students' performance goal orientation in science classes on 6th graders' science achievement and science learning motivation. Two classes (47 students) from an elementary school were respectively assigned to a control group and a treatment group. A performance goal orientation test and a science learning motivation test were administered as pretests. The intervention of cooperative learning lasted for 24 class periods. A researcher-made achievement test and the science learning motivation test were administered after the instructions. ANCOVA results indicated that the score of the treatment group was significantly higher than that of the control group in the achievement test. However, no interaction was found between the cooperative learning treatment and the levels of students' performance goal orientation. There were significant aptitude-treatment interactions in science learning motivation.

본 연구의 목적은 IMF의 어려운 경제환경하에서 과거와는 달리 기업이 생존 및 번영을 위해서는 어떤 신제품개발 전략을 세우고 그 전략은 기업의 신제품 성과에 어떤 영향을 미치는지를 알아보기 위함이다. 이를 위한 연구 질문으로 기업은 신제품개발을 위한 상이한 경영전략을 사용하는가 ? 그리고 신제품개발 전략은 신제품개발 성과에 영향을 미치는가를 파악하고자 하였다. 본 연구는 신제품개발 전략유형 즉 신제품 특성, 시장특성, 기술특성 그리고 프로그램 특성의 4가지 유형에 의해 실증분석을 한 결과 균형전략, 다각화전략 그리고 시너지추구 전략군 등 3가지 유형으로 집단화할 수 있었다. 균형전략군은 기술지향성과 마케팅지향성을 동시에 보유하고 있는 전략군이고, 다각화전략군은 새로운 고객의 욕구충족을 위해 새로운 유통경로와 촉진활동을 촉진하는 전략군이며 마지막으로 시너지추구 전략군은 상대적으로 낮은 R&D비용을 지출하고 위험성이 낮고 기술수준이 낮은 신제품을 개발하는 전략유형이다. 그리고 신제품전략 유형에 따라서 신제품개발 성과에 가장 많은 영향을 미치는 것은 제품특성(3.4524)이고 그 다음으로 시장특성(3.4470), 기술특성(3.4270) 순으로 나타났다. 따라서 위의 분석 결과들은 IMF시대의 불확실한 경영환경에 대처하면서 기업의 생존 및 번영을 책임지고 있는 신제품개발 담당자들에게 경영적 함의를 제시할 것이다.
