In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.
Dewey와 Russell의 實驗學校 考察 : 兒童敎育實際를 中心으로 The practice of child Education
李恒宰 순천향대학교 1991 논문집 Vol.14 No.3
This study is to investigate the experimental schools of John Dewey and Bertrand Russell. There have been many other studies on the contribution of J. Dewey and B. Russell on school society, but they were confined to educational theories of Dewey's and Beacon Hill's schools; however, their experimental schools have been neglected. Therefore, instead of fragmentary aspects, this study is to investigate their child education practices. This paper is a comparative study on the experimental schools of J. Dewey and B.Russell. The purposes of this study are as follow. 1. To compare experimental schools of child education of J. Dewey and B.Russell. 2. To obtain suggestions for modern education of Korea. The common factors of this study are the emergence from traditional teaching method and the innovation of a view of school. This study will provide a good suggestion for Korean education, and contribute to social reconstruction; the followings are to be investigated. First, the educational theory and philosophy of Dewey and Russell were based on the concept of freedom, and they practiced it through experimental schools. Second, desirable understanding of J.Dewey and B.Russell will bring out a good suggestion for the establishment of educational objectives of Korea. Third, the freedom of J.Dewey, and the freedom and discipline of B.Russell must be practiced in education. Freedom in education is necessary.

Some concepts of modern mathematics give rise to the new contents of school mathematics in accordance with the modernization movement of mathematics education. The trasformation of the figures is one of contents. In the present paper, to find out the effective teaching methods for the transformations of figures, we study the followings; (1) the structures of various transformations (2) analizing the curriculum and the mathematics textbooks (3) organizing the development of contents by logical arguments (4) pointing out difficult aspects of contents which can be found in the educating place.
Application of CCD Camera for Optical data Acquisition ; Dynamic LEED and RHEED
閔恒基,金載成 弘益大學校 科學技術硏究所 1993 科學技術硏究論文集 Vol.3 No.-
CCD 카메라와 Frame Grabber를 이용하여 광학적 영상을 전기적 신호로 바꾸어 LEED 패턴을 분석하는 장치와 프로그램을 개발하였다. 이 장치는 적은 비용으로 마련할 수 있기 때문에 광범위한 분야의 연구자들에게 편리한 도구로 사용할 것이 기대된다. RHEED에의 응용 프로그램은 밝은 점(spot)이 고정되어 있으므로 더욱 간편해 진다. I/V 곡선에 대한 이론값과 실험값 사이의 비교분석은 진행 중에 있다.
영상 회의 시스템의 성능 Ripple Effect 분석 모델
성재철,최항묵,박세명 인제대학교 1999 仁濟論叢 Vol.14 No.3
소프트웨어 시스템의 변경은 연관된 다른 요소에 영향을 미치게 된다. 특히 모듈 단위로 구성된 소프트웨어의 경우, 하나의 모듈이 변경됨에 따른 성능 변화의 파급 효과가 발생한다. 이는 소프트웨어의 유지 보수를 어렵게 만들고 비용의 증가를 가져올 수 있다. 본 논문에서는 현재 개발 중인 의료 영상회의 시스템을 모듈 별로 분리하여 모듈 간의 성능 파급 효과 분석을 위한 모델을 제시한다. As every knows, modification of a software system affects other related components in the software. Specially, modification of a module in a software, combined with module units, makes Performance Riffle Effects. This makes it difficult to maintain a software and cost a lot. This paper suggests a model for analyzing Performance Ripple Effects among modules by separating the Medical Image Conference System(MICS), which is being studied, into several modules.

This paper presents a tunable filter that can be used in front stage of UWB receiver operating under 2GHz frequency range. It presents the optimum design method of comb-line structure tunable filter keeping the fixed bandwidth and attenuation characteristic in the tunable frequency range. This filter is implemented by applying a tunable capacitor, obtained by reverse-biased varactor diode, to a capacitor used in SIR structure. As a result of tunable filter measurement, the center frequency was little moved down. Its bandwidth was almost corresponded with the result of a simulation but did not meet the given 100MHz bandwidth.

The purposes of this study were to investigate possibilities and objectives of environmental education, and to analyze the environmental content elements available in the 7th curriculum, and to suggest strategies for the development of teaching materials for the improvement of pro-environmental power in practical arts education. This study was carried out through review of literature and discussions with panels of judges composed of experts in the environment related fields. The results of this study were as follows; 1)It was identified that an environmental education through practical arts subject was very efficient because principles of environmental education coincided with characteristics of practical arts education which emphasizes on real life, direct experience, and inter-disciplinary approach. 2)It was identified that an environmental education in elementary school was reflected on different courses in a distributed way, contents related to the environmental education such as resources, environmental conservation, an environmental hygiene has been included in the practical arts subject from the 1th curriculum to the 7th curriculum of the elementary school. 3)It was identified that contents such as orientation of jobs related an environment, separate garbage collection, food hygiene, recycle of waste articles, environmental pollution, and an environmental conservation could be reflected in the 7th curriculum. 4)Proposed strategies for developing teaching materials related to the improvement of pro-environmental power in practicalarts education ware a consideration of environment education frame in entire school system, an emphasis of practical and experience, the maximum uses of concrete stimulus, the uses of various places and facilities, the active uses of web site through internet.
