고유전율의 유전체 세라믹 기판을 사용하여 GPS(Global Positioning System) 위성수신용 단일 급전 원형편파 마이크로스트립 패치 안테나를 제작하여 시험하였다. 제작된 안테나는 작기 때문에 차량과 같은 이동체에 사용하기 적합하였다. 우선회 원형편파를 구현하기위해 정방형 패 치면의 모서리를 잘랐다. 급전 방식은 패치면의 50Ω지점에 동축 프로브로 하였고, 시뮬레이션 하여 1.57542GHz에서 공진되도록 설계하였다. 제작된 안테나의 반사손실은 -13.394dB이고, 공진 주파수는 설계 주파수보다 약간 높은 1.591GHz로 측정되었다. 따라서 이 안테나는 GPS 위성수신용으로 사용하기에 적합하였다. Single-feed circularly polarized microstip patch antenna for GPS Satellite Receiver was fabricated by using high permittivity dielectric ceramic substrate and tested. This miniature antenna is suitable to be used for mobile such as cars. By truncating the corners of squared patch, right hand circular polarization was realized. It was fed by coaxial probe on patch at 50Ω impedance, and was simulated to resonate at 1.57542GHz. The return loss of this antenna was -13.394dB, and resonant frequency was measured at 1.591GHz higher than desired frequency. Therefore, it could be used for GPS Satellite Receiver.

In handball games, There is a close correlation between the results of games and how defense pattern are effectively changed following the attacks of the opposite following game times. That is, effective attack pattern have important effects on the results of games. This study is examines of the differences in the results of games following defense strategies which greatly influence on the opposite team in handball games. For the study, games of men's professional teams were photographed. Test was executed to examine the frequencies of the pattern and positions bringing marks obtained by the opposite team, which were done by goal keepers, following various defense type of each team and following defense pattern. ANOVA was executed for the pattern and positions bringing marks obtained by the opposite, which were done by goal keepers. In addition, forms and positions bringing marks were obtained by the opposite, which were done by defences, following various defense positions. When there was a difference between team levels, post tests were done and here are the results: 1. Defense abilities in handball games are diverse, following attack pattern, and they are connected directly with game ability. Therefore, defense abilities cannot be neglected. This study shows that according to the levels of games, such as advanced, intermediate, and beginner, defense pattern are different in each team, having various effects on game ability. Thus, developments of various strategies appropriate for teams' characteristics have great influences on game ability. 2. Defense pattern following times are connected directly with the progress of game. The analysis result of defense pattern following times shows that each team keeps fixed defense patterns appropriate for its characteristics. However, the need of a post study is suggested since defense pattern are a little different according to the characteristics of the opposite team on the field.

日本經濟의 構造分析과 한국의 對日輸出擴大方案에 관한 硏究

金錫千 경성대학교 1989 論文集 Vol.10 No.1

Korea has recorded trade deficit of 40 billion dollars (US) since Korea restored diplomatic relation with Japan in 1965. Especially in 1987, Korean export to Japan recorded 8.4 billion dollars and Korean import from Japan recorded 13.6 billion dollars. Therefore, 5.2 billion dollars trade deficit happened. Japan think such chronic deficit caused by different trade structure between two countries, but Korea think it caused by Japanese own measures. Anyhow, Japan is the largest market next to U.S.A. for Korea. Japan has suffered from the yen appreciation since Plaza Agreement in Sept. 1985. This came from Japanese tremendous trade surplus, which forced Japan to open its market to the world including Asian NIEs since 1985. Recently, durable goods and jeep(car). Meanwhile, Japanese consumers are inclined to buy foreign products if they are satisfactory in price and quality. Under these circumstances the way to strengthen the competitive power of Korean products in Japanese market can be summarized as follows: 1) Improvement of quality through craftmanship: Korea's exports have expanded in the volume and amount because Korean government adopted exportdrive police in 1962. But there is no progress & in profitability because of inferiority of the quality which resulted from lack of craftmanship of the skilled labor. This craftmanship is essential to high quality. We should not overpass the fact that the products sold in Japan can be sold every-where in the world. 2) Development of technology and enlargement of technology introduction: Most of our exports depends on Japanese technology and the degree of the technological dependence is deepening. This is also the reason why we cannot overcome the chronic trade deficit between countries. Therefore, the introduction of technology should be multilateral and the government should stress on the technology development to increase competitive power of Korea's products in Japanese market. 3) Improvement of the image of our export products: Recently Japanese consumers are asking for perfect quality and functioning and their tastes show preference to high quality, differentiation and full service after sale. Accordingly, we should diversify products and brand in main export items. Also we should provide high quality, perfect functioning nice design and trade mark to improve the image of our products. 4) Efficient untilization of distribution system in Japan: It is well known that distribution systems are closed in Japan. Recently, however, distribution business circles in Japan face big changes. Large-scale firms reformed traditional distribution system by providing direct sale system to satisfy the various tastes of consumers with lower prices. We should establish the sale policy which can use this reformed distribution system in Japan. 5) Strengthening export marketing strategies to Japan: It is true Korean products still have the image as low quality and low-price products among Japanese consumers. Therefore, Korea's high quality products cannot be evaluated appropriatly in Japan because of this image, and it is difficult to reserve market share so far as new products are concerned. Various and flexible marketing strategies are demanded to offer the new image of our products to Japanese consumers.

Korean Medical Licensing Examination(KMLE) 2002 focused on evaluation of the integrative medical knowledge such as primary clinical care or problem-solving competence. We analyzed the correlation among the year-wise student academic scores(grade score), trial examination scores and KMLE score by correlation analysis and multiple regression method. Four times of trial examination were taken in 2001, which were composed according to the principles of KMLE. Trial examination scores were significantly correlated with student grade scores (p(0.05). KMLE score also correlated with student grade score a nd trial examination score. The grade score at senior had higher correlation coefficient than the grade score at junior in correlation analysis. In multiple regressions, grade score at senior and mean score of trial examinatio n score were significant variants affecting KMLE score. Based on this result, regression formula such as [KMLE score] = 110.596+21.449^*[6th grade score of student] + 0.577^*[mean of trial examination score] was established (R2=0.764, p<0.001). Our results show that the trial examination is useful evaluation tool for final assessment of medical achievements. Also a trial examination is used as a reference data for student guidance and control in preparing for KMLE.
