The incidence of Sexually Transmitted Disease has risen despite the progress in its diagnosis and treatment methods. For the effective control programs of S.T.D it should be required medical and social approaches. This survey was conducted in Young Dung Po and Sung Buk areas from June, 1986 to September, 1986. The 1185 prostitutes were studies in order to determine the prevalences of sexually transmitted disease. The results were as follows: 1. The average age of prostitutes was $24.0\pm3.9$ years. The age group of 21-25 years old was the highest level of about $70.3\%$. 2. The positive rate on non Gonococcal urethites was $9.1\%$ at Sung Buk area and $15.3\%$ at Young Dung Po area. 3. The positive rate of Neisseria Gonorrhoeae on culture of TM media was $6.4\%$ or total level and incidence ratio of Neisseria Gonorrhoeae: Non Gonococcal urethritis was 1: 1.7. 4. The positive rate of PPNG was occupied about $26.3\%$ among the total NG positive case. 5. The positive rate of VDRL Slide Test was $2.9\%$, and antibody Titer level of 1:2 was $38.8\%$. it was the highest of all Titer distribution.

Objective: The aim of this study is to develop an office chair enabling to keep working at reclined sitting posture. Background: Sedentary workers are supposed to change the posture frequently during long hours of sitting. A reclined sitting position has been recommended to reduce disc pressure. But slumped sitting posture caused by the buttock sliding forward without any adjustment of back reclining is commonly observed. The worker seems to have tendency to change the sitting posture maintaining working condition. We assumed the reason to be their hands movement away from the working space when tilting backward. Method: Slide mechanism allowing seat to move forward was designed to maintain the hand position in working space during reclining. A prototype was manufactured and tilting motion was analyzed using motion capture system. Four experiment chairs were tested including the manufactured prototype chair and three other commercial chairs. Results: A backward movements of the hand position were 13.0mm, 101.7mm, 156.1mm and 139.3mm at the prototype chair, compared to chair B, chair C and chair D, respectively. And the movement was remarkably small at the prototype chair. Conclusion: The developed seat sliding chair allows back tilting maintaining hand position at working space. We expect the user tilting back more often than normal tilting chair during seated work. But further investigation is required to figure out the effectiveness of the developed chair using prolonged working hours. Application: The developed office chair directly affects commercialization.

본 논문에서는 한 개의 카메라와 한 대의 환등기(LCD 환등기 혹은 슬라이드 환등기)를 이용하여 2차원 얼굴 영상으로부터 3차원 얼굴 형상을 모델링하는 방법을 제안한다. 환등기를 이용하여 사람 얼굴에 라이트 빔을 투영하고 이를 조금씩 이동시키며 영상을 획득한 뒤 각 2차원 영상의 지역적 정보와 영상들 사이의 시간적 정보를 함께 이용하여 3차원 형상을 복원하는 방법을 채택하였다. 제안된 방법에서는 특정이 서로 다른 영역들의 효과적인 3차원 좌표 모델링을 위해 영상을 그림자 부분 얼굴 부분 그리고 머리카락 부분으로 나누어 처리하는 지역 분할(region segmentation) 기법을 도입하였고, 2차원 얼굴 영상 획득 시간을 줄이고 고속 3차원 스캔을 위하여 한 영상 안에 다수의 라이트 빔(multiple light beams)을 이용하였다. 또 한 라이트 빔의 경계를 정확하게 검출하기 위하여 라이트 빔 캘리브레이션(light beam calibration) 기법을 제안하여 사용하였다. 실험 결과 제안한 방법을 통해서 머리카락 부분을 포함한 전체 얼굴 영역에서 향상된 3차원 모델링 결과를 얻을 수 있었다.

This survey study is to find out children' needs of 'D' child park to remodel into a new one and their common opinions to the child playground, and to contribute this results to drive alternative plans. This park is very old and located in detached residental zone, Wooa-dong, Deokjin-gu, Jeon-city. This was performed by a questionnaire survey method, and the questionnaire was designed by researchers considering relative literatures. Data were collected from 198 children, who had attended elementary school in Wooa-dong. By analyzing those data, findings were as follows : 1) To play experience of 'D' child park was very important for children, so they memoried it. Above all, they membered the perception of 'D' child park through playing with play facilities and the communication with their friends. 2) Children would like to play unrestricted plays, but to need traditional play facilities as like a slide and a swing. So, future playground would be planned to adventure playground with some traditional play facilities.

1.5 cc 이하의 안테나 체적을 갖는 소형 안테나의 이득을 향상시킬 수 있는 3차원 구조의 휴대폰 내장형 안테나를 설계하고 이를 제작하였다. 소형 안테나 경우, 공진을 위해서 안테나를 복잡하게 구부리게 된다. 이러한 구부림은 전류 상쇄 작용을 발생시킴으로써 결국 이득 감소를 초래한다. 본 연구에서는 안테나의 구부림을 최소화하여 전류 상쇄를 줄였다. 짧은 안테나 길이의 보상과 방사 소자로의 동시 역할을 위해 헤릭스 소자를 사용하였다. 타당성을 입증하기 위하여 1.5 cc 체적으로 설계한 안테나를 프레스 공법으로 제작하여 2중 대역 휴대폰에 적용하였다. 측정 결과, GSM/USPCS 대역에서 슬라이드 다운 및 업일 때 효율과 이득은 각각 최대 27.73 %, 46.84 % 및 0.29 dBi, 2.27 dBi로 소형임에도 불구하고 양호한 특성이 나타났다. 방사 패턴은 2대역 모두 H-면 전방향성 특성을 보였다.

The growing behavior of Candida albicans in various concentration of glucose and corticosteroid media was studied with the method of modified hanging slide culture. The strains of Candida albicans used in this study were obtained from vaginal swab from outpatients and were isolated from cultured colonies on Sabouraud's glucose agar media. To detect the budding rate of blastospore, the diluted suspension of Candida albicans in normal saline were inoculated into various concentration of glucose (Gl, G2, G3, G4), corticosteroid (S1, S2, S3, S4) and corticosteroid with 10% pepton broth (D1, D2, D3, D4) respectively and cultured at room temperature $(22{\sim}25^{\circ}C)$. The number of budding of blastospore were counted under the high power field of light microscope (400X) at specific time interval, e.g, 1, 2, 3, 6, 9, 12, 18, and 24 hours after inoculation. The results are as following: 1. The most effective budding rate was seen in G4 media (1.25% glucose) in 18 hours aft inoculation (89%). 2. The budding rate in Sabouraud's glucose broth with various concentration of dexamethasone added, was not significantly different from that of simple Sabouraud's glucose broth within 18 hours after inoculation, but there was statistically. significant difference in two budding rate at 24 hours observation. 3. The budding rate in 10% pepton broth media with various concentration of dexamethasone was almost same budding rate in control group, which is normal saline and 10% pepton broth, except on 2 and 24 hours results.

The serological typing of staphylococcus hyicus subsp. hyicus isolated from pigs with exudative epidermitis and healthy pigs was attempted by slide agglutination technique with absorbed sera prepared from antisera against swine strains of the organism. Of 204 Staph. hyicus subsp. hyicus isolated, 202 (99.0%) were classified into 6 serotypes tentatively designated as A, B, C, D, E and F. The organisms were found to possess common antigens and a strain specific antigen. In 26 epizootics of exudative epidermitis, type A was found in 4(15.4%), type B in 12(46.2%), type C in 9(34.6%) and type E in 1(3.8%). All of the piglets of each affected litter were infected by serologically identical strain. In 178 strains isolated from the skin of healthy pigs, type A was found in 14.1%, type B in 23.0%, type C in 30.3%, type D in 1.7%, type E in 7.9% and type F in 21.9%, and 2 strains were untypable. There was a difference in the occurrence of serotypes of Staph. hyicus subsp. hyicus among the farms examined.

반도체 광 증폭기와 파브리-페롯 가변 필터를 이용한 파장 훑음 레이저 기반 광 결맞음 단층 촬영을 구성하고, 이로부터 선명한 이미징을 얻기 위한 파수 영역 선형화를 구현하였다. 파수 영역 선형화는 5 개의 서로다른 공진 파장을 가진 광섬유 격자로 이루어진 어레이를 이용하여 보간법으로 수행하였다. 샘플단의 1 mm 깊이에서 파수 영역 선형화를 수행한 후 점 분포 함수(point spread function)로부터 측정한 SNR(signal-to-noise ratio)은 12 dB 향상된 값을 얻어냈다. 또한 파수 영역 선형화 전과 후에 대해 슬라이드 글라스를 이용하여 OCT 이미징을 얻어낸 결과 파수 영역 선형화가 매우 잘 되었음을 확인할 수 있었다.

The purpose of this study is to evaluate and analyse the characteristics and images of interior environment design in the living rooms, bed rooms and kitchen of the apartment, using the e-model houses of the apartments that will be constructed by 10 construction companies and be occupied after 2006. The 29 defined terms were used in this study to describe the interior image trend. They were systematized by a 5-point scale for the SD evaluation, and were used as a tool to analyse the images. The images were evaluated by methods, such as monitoring the image photos showing the individual rooms in their e-model houses and making their slide film, and reediting them to understand interior atmospheres completely. The image evaluation was performed by the group of 2nd and 3rd year students in the Housing & Interior Design of D University on December 9, 2005, and the data were analysed using SPSS Statistical Program 12.0 for Windows.
