1000MW급 증설과 관련하여 발전소 주변지역으로부터 민원이 제기된 3000MW급 화력발전소는 넓은 평지에 위치하여 발전소의 영향이 그대로 주변지역에 전달되는 상태임에도 일상 소음레벨이 환경 기준치를 만족하는 상태였으나 향후 증설에 따른 소음도 증가에 대비하여 소음영향을 예측하고 저감 대책을 검토하였다. 대형 화력발전소의 옥외소음원은 Booster fan, I.D.fan, 주변압기, 대형 철탑, 해수순환수 펌프 전동기, 증기방출관 등이 있다. 대상 주거지역의 경우는 대형팬에 의한 지향성이 크게 나타났다. 따라서, 발전소가 주변지역에 주는 소음별 기여도를 평가하고 영향이 큰 대형팬에 대한 대책으로써 기기주변에 방음벽을 설치하는 방안과 함께 소음원의 크기를 저감시킬 수 있는 소음기 대책을 추천하여 증설 예정호기를 비롯한 기존 호기중 주거지역에 영향이 큰 3000MW에 대하여 수립함으로써 소음저감 목표치를 달성하는 결과를 도출하였다.

The purpose of this study was to investigate the effects of a quality assesment of a university dormitory foodservice on the satisfaction degree, value awareness and relationship intention toward the foodservice. A total of 328 questionnaires were completed. Using SPSS package, Cronbach's alpha, analysis of variance and multiple regression analysis were applied. The results are as follows. First, the quality assessment of the foodservice varied depending on the period of service utilization. Customers of less than one year rated the nutrition supply of the university foodservice the highest, followed by those who were customers for more than 3 years and those who were customers for 2 to 3 years, respectively. Second, the quality assessment of the foodservice was substantially influenced by price as compared to service quality. Third, the quality assessment was significantly influenced by the price appropriateness of the foodservice. Fourth, foodservice assessment items such as customer-centeredness, pursuit of nutrition supply and food quality had a meaningful effect on the satisfaction degree toward the university foodservice. Fifth, customer-centeredness, pursuit of nutrition supply and food quality had a significant effect on relationship intention. Sixth, among the items of value awareness for the foodservice, value assessment as compared to service quality, and not price appropriateness, greatly affected the relationship intention. Seventh, the overall degree of satisfaction for the foodservice affected the relationship intention.

The purpose of this study is to examine the effect of CEO's entrepreneurial orientation on innovation performance and business performance, and the mediating effect of innovation performance on the relationship between entrepreneurial orientation and business performance in small and medium-sized venture-enterprises (SMEs). To test the hypothesized relationships, we have conducted a survey of Korean SMEs. After excluding unanswered and untrustful item questionnaires, the final sample size for this study is 110 SMEs. The major findings of the empirical research are as follows. First, CEO's entrepreneurial orientation had apositive influence on innovation performance of a firm. Second, CEO's entrepreneurial orientation was positively related to business performance of a firm. Third, innovation performance had the partial mediating effect on the relationship between CEO's entrepreneurial orientation and business performance of a firm. That is, this result indicates that CEO's entrepreneurial orientation indirectly effects on business performance through innovation performance. Based on these findings, implications of the research findings are discussed, and recommendation for future research are provided.

The purposes of this study are to explain and identify the frame of structural relations of learning orientation, self-efficacy, learning transfer and job performance of farmers who participated in the strong and small farms education. This is an experimental research with the data collected from 495 farmers who have taken the farm education. Based on the collected data, the study conducted a structural equation modeling(SEM) to confirm the validity and analyze the structural relations of the suggested model. Using measured and latent variables drew from the analyses, the study set a structural equation model and tested the model by analysis of the structural equation modeling with AMOS 18.0. The results found from the empirical analysis can be summarized as follows. 1) Learning orientation and self-efficacy positively influenced job performance through learning transfer. 2) The hypothesis that learning orientation would have direct impact on job performance was not supported. 3) The strong and small farms education is useful to expand learning transfer and to enhance job performance. So, government policy support has to reinforce learning support on farmers in order to achieve high performance of learning and job management through farm educations.

본 논문에서는 광속에 비해서 대단히 낮은 속도로 운동하고 있는 선형, 등방, 균질 매질내에서 크기가 파장과 동등정도이거나 그 이상인 Circular Loop Antenna의 방사특성을 고찰하였다. 고찰에 있어서 우선 운동매질내에서의 전자파방정식인 Maxwell-Minkowski방정식을 토대로 하여 Circular loop antenna에 해당하는 Vector potential을 유도하고 전자계식을 구하였다. 다음 이와같이 유도된 식들로부터 특정한 파장과 속도에 대한 전자계를 계산하고 field pattern을 도시하였으며 이 pattern과 정지매질에서의 field pattern을 비교 검토하였다. 검토한 결과, 지향성은 loop면에 평행한 속도성분에 한하여 속도방향으로는 축소되고 속도와 반대방향으로는 신장되는 사실이 발견되었으며 이 경향은 속도가 클수록 동진주파수가 높을수톡 크게됨을 알수 있었다.

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.
