Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.

Back ground : This study was designed to evaluate the relation fungal infection with the males and females with/without occupation and to evaluate cause of fungal infection Methods : This study was done via direct interview and KOH mount with 03 patients who are oupatients in a university hospital from July 2000 to Aprill 2001. They were divided into three groups, males with occupation, females with occupation, females withoup occupation and sudied by sex, age, duration, types of dermatophytosis, site of infection, infection in families. Results : The results were as follows 1. Fungal infection was 40% in males with occupation, 24% in females with occupation, 36% in females without occupation. 2. The site of fungal infection was the offices(42.5%), the families(30%) in men with occupation and the families(54.2%), the offices (41.7%) in females with occupation and the families(72%), the others(11.1%) in females withoup occupation. 3. The members of the families were the spouses(32.5%), the parents or children(32.5%) in men with occupation and the spouses(41.7%), the parents or children(25.0%) in females with occupation and the spouses(69.4%), the parents or children(13.9%) in females without occupation. Conclusions : In our study, the results showed no difference in the fungal infections among males with occupation, females with occupation and females without occupation. Fungal infection of females without occupation was spread in the families and by the pouse among the members of the families

This study describes liquid-solid extraction for the adsorption of organic compounds from aqueous solution by using XAD-2 resin. The adsorption behaviors of organic compounds on XAD-2 resin have been investigated. As a result, the following conclution have been obtained. 1. The adsorption behaviors of aromatic compounds on Amberlite XAD-2 are caused by van der waals attraction between the organic molecule and XAD-2 resin matrix. 2. The adsorption on XAD-2 are influenced by the following factors: 1) Shaking time, 2) Concentration of organic solvent added, 3) Polarity and position of substituted groups in an organic molecule, 4) Ionization constant of organic molecule, 5) Molecular weight of organic sample, 6) pH value of medium.

One of the important technical issues is how to decrease thermal expansion of ballscrew in proportion to the increase of machining speed, when measuring force of stretch of ballscrew, since not only actual expansion and the value of bending have to be considered, it's impossible to define that exact value of expansion. In addition, support bearings of ballscrew gain considerable force in axial direction. It also generates thermal expansion on the ballscrew, and deteriorates the bearings. In conclusion, it's impossible to give the pretension enough to absorb the all elongation due to thermal expansion generated during machine running. If gave, bed, column and saddle are all bent to change machine accuracy, and the support bearings of ballscrew are damaged. The purpose of this paper is to study the pretension of support bearing of ballscrew in machine tool.

본 연구는 두부 외상후 기질성 정신장애로 진단된 환자의 자료를 토대로 K-WAIS의 요인구조를 탐색해 보았다. 연구 대상자는 17세에서 72세의 남녀 138명으로, 8개월 동안 호남지역에 소재하고 있는 대학병원 신경정신과와 정신과병원에 내원한 두부 외상으로 인한 기질성 정신장애 환자들이었다. 자료분석은 주성분분석모형을 이용하여 요인분석을 하였다. 기초구조 계산법으로는 주축분해법을 사용하였고, 기초구조에 대한 회전방법으로는 직각회전방식을 사용하였다. K-WAIS의 요인구조를 알아본 결과, 두부 외상후 기질성 정신장애로 진단된 환자집단에서는 2개 요인(언어적 이해력 요인과 지각적 조직화 요인)이 추출되었는데, 이 들 2개 요인들의 전체변량은 73.7%이었다. 언어적 이해력 요인은 어휘문제, 이해문제, 산수문제, 기본지식문제, 공통성문제, 숫자외우기로 구성되어 있었으며 전체변량의 62.0%를 설명하고 있었다. 지각적 조직화요인은 동작성검사에 속하는 모양맞추기, 차례맞추기, 토막짜기, 바꿔쓰기, 빠진곳 찾기 소검사로 구성되어 있었으며, 전체 변량의 11.7%를 설명하고 있었다. 본 연구에서 밝혀진 K-WAIS의 요인구조는 두부외상후 정신장애로 진단된 환자의 K-WAIS 자료를 임상적으로 해석할 때 중요한 의의를 지닌다고 볼 수 있을 뿐만 아니라, K-WAIS 단축형을 제작할 때 기초자료가 될 것으로 생각한다. Objectives : The purpose of this study was to investigate the factor structure of the K-WAIS. Methods : The sample was consisted of 138 patients with organic mental disorder due to head trauma. A principal component analysis was used worth varimax rotation. Results : Two factors in a sample patients with organic mental disorder due to head trauma were abstracted from the K-WAIS by factor analysis. Variance of the two factors was 73.3%. And variance of factor 1(verbal comprehension) factor 2(perceptual organization) were 62.0% and 11.7%, respectively. Conclusion : Two factors in a sample patients with organic mental disorder due to head trauma were abstracted from the K-WAIS using the principal component analysis by varimax rotation.

본 연구는 회계정보와 주가사이의 관계를 연구하는 실증적 연구에서 회계정보가 자본시장에서 유용하다는 관점에 중점을 두어 연구를 시작하였다. 기업의 연구개발비는 신기술과 신제품의 개발에 영향을 주어 기업의 초과가치를 향상시킬수 있고, 또한 광고선정비도 기업의 초과가차에 영향을 줄것으로 가정하여 이들 변수들간의 상관관계를 검증하였다. 기업의 상대적초과가치는 자보시장에 정보효과를 주어 누적초과수익률과는 임의 관계가 있을 것으로 가정하고 이 두변수간의 상관관계를 분석하였다 주기검증기간을 결정하기 위해 감사보고서일을 기준으로 하여 일별초과수익률을 구하고 변수와 가장 유의성이 높은 기간을 대상으로 하였으며, 상대적초과가치비율과 감사보고서일을 기준으로 한 일별초과수익률·누적초과수익률과의 관계를 회귀분석방법으로 실증분석하였다. 실증분석시 이익지속성 변수로 상대적초과가치비율을 이용하여 분석하였다. 실증분석 결과는 연구개발비는 상대적초과가치비율에 유의적인 양(+)의 상관관계를 보여주나 광고선전비는 상대적초과가치와 음(-)의 상관관계를 나타내며 유의적이지도 않았다. 초과수익률 산정시 감사보고서일을 기준으로 유의성이 높은 +2일에서 +23일을 검증기간으로 하였고, 이 검증기간의 상대적초과가치비율과 누적초과수익률에서는 지속적으로 음(-)의 상관관계를 보이고 있는데 이는 IMF로 인한 주가하락에 기안한 결과로 본다. 본 연구의 결과는 이익공시일의 결정에 있어서 감사보고서일의 전 후 유의성을 검증하여 회계정보의 누출여부를 검증하였고, 이들 회계정보가 이를 필요로 하는 정보이용자에게 유용한 정보가 될 것으로 본다.

Atmospheric Plasma Cleaning (APC) was studied for the residual rolling oil contaminants on the surface of cold rolled Stainless Steel after optimizing APC conditions. Electrodes were placed at a distance of 10mm, with an RF power of 220W, and line velocity of 0.5m/min. The residue left by APC was 0.78mg/m², which was less than that of the approximate 1mg/m² by other classical cleaning methods. Especially, APC combined with pre-cleaning by 550℃Nitrogen gas gave a residue of only 0.01mg/m². Cleaning effect are also improved when oxygen gas is added to the atmospheric plasma. It was confirmed by the investigation of the official Korea Chemical Analysis Center that the APC-hot nitrogen method is superior to other methods. The residual contaminants for different methods were as follow : the classical method : about 1mg/m², APC : 0.78mg/m², and APC-hot nitrogen : 0.10mg/m².

홍성오,조규재 朝鮮大學校 機械技術硏究所 1999 機械技術硏究 Vol.2 No.1

Development of high speed feed drive system has been a major issue for the past few decades in machine tool industries. The reduction of the tool change time as well as rapid travel time can enhance the productivity. However, the high speed feed drive system generates more heat in nature, which leads thermal expansion that has adverse effects on the accuracy of machined parts. The detail of the model proposed is described in the paper together with the experimental methodologies using a proposed compact measurement system to examine the validity of the proposed approach. The results showed the machining accuracy could be maintained to better than ±5㎛ while using this sensor.

This study is designed to grasp the elements and situations of stage fright in order to propose a part of ways to cope with it. We make 511 top-class high school players, male and female, in the central districts (Seoul, Inchon, Kyungki, Chungbuk, and Kangweon Province) on object of questionnaire, and get the following results. Through players generally have all-round characters they show weakness in the superiority and emotional stability while showing strength in the sonformity. This fact comes to be related to the elements which cause stage fright. Physiological changes also have many effects on the symptom of stage fright. Especially, stage fright increases when players show sensitive reaction to the self-consciousness of final consequence which comes from the tension or uneasiness of sympathetic nerve, Thus, it turns out that players make use of reducing psychological burden by physical exercise or adjusting the level of demanded result in order to release the stage fright.
