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.

최근 홈 네트워크 산업이나 지능형 주거관리 시스템의 필요성과 관심이 증가하고 있다. 이와 같은 분야에서는 무엇보다 효율적인 측정 시스템에 대한 연구가 선행되어야 한다. 따라서 본 논문에서는 센서 측정 시스템 설계에 관한 기초 연구로서 실내 환경에 적합한 온도 측정 시스템을 설계해 보고 그 특성에 대해 나타내었다. 설계한 시스템의 구성은 크게 온도 센서로부터 온도 변화를 검출하는 데이터 획득부, 신호처리를 위한 제어부 그리고 측정된 온도 데이터를 전송하기 위한 RF 송수신부로 나누어진다. 설계된 측정 시스템에 거리변화 및 장애물 유무에 따른 영향을 살펴보고, 안테나 변경에 따른 성능 차이를 살펴보았다. 실험 결과 10m 이내의 실내 환경에서는 본 논문에서 제안하고 설계한 측정 시스템을 사용하여 데이터의 실시간 처리가 가능하였다. 또한 이를 바탕으로 다중 센서 측정 시스템 구현이 가능함을 알 수 있었다. Recently, the need for intelligent sweet home systems and home network industry is increasing. In this field, a study on efficient measurement system is preceded by the other subjects. Therefore, in this paper, a study on efficient sensor measurement system, temperature measurement system suitable for room environment is designed and its property is given. We designed temperature measurement systems consisting of data acquisition part as a temperature sensor, control unit for signal processing and RF moduls for data transmit. The results of experiment showed real-time processing in the room environment within 10 meter. It also showed the possibility of multi-sensors measurement system.

This study was conducted to identify irradiation-derived volatile components, having positive-correlation with irradiation doses, which may play roles as maker materials for detecting post-irradiation in pork meat. The volatile components of irradiated(0, 1, 3, 5 and 10 kGy doses) pork(Belly) meat was analyzed by liquid liquid continuous extraction(LLCE)/GC/MSD methods. By the results of linear regression analysis between irradiation doses and volatile component amounts in fresh pork, 3 compounds including γ-octalactone(r=0.82), 1-octen-3-ol(r=0.90) and butanoic acid(r=0.81) had high correlations with irradiation doses.

Dental Caries which has high prevalence rate, accounts for majority of dental diseases. Many treatment and preventive treatment has been developed, thereby reducing the prevalence rate, but in our country, flouridization has not spread widely yet, so prevention has not been done satisfactorily. When dental caries progresses, irreversible damage of tooth structure occurs. In initial dental caries. Demiteralized tooth structure can be remineralized, so restorative treatment is unnecessary. In the study, 20 teeth restored with composite resin without fluoride release were used and divided into two groups. Incipient dental caries were artificially made and remineralization procedure was done for 1 and 2 weeks, for each group. Changes in mineral contents aroud the margins were analysed with confocal laser scanning microscope. The results were as follow. 1.Both total fluorescence of the lesion and average fluorescence of the lesion of remineralized samples decreased compared to demineralized state. (p<0.01) 2.Confocal laser scanning microscopy can be used in quantitative analysis of mineral change. In result, confocal laser scanning microscopy can be used in quantitative analysis of mineral change and it could be used in many different fields of dentistry in the future. Key words : Confocal laser scanning microscopy. Demineralization. Remineralization, Initial dental caries

This study was conducted to investigate the effects of the addition of activated charcoal (AC) and oak charcoal on the ruminal fermentation characteristics, nutrient utilization in Korean native goats. Compared to reference diet, digestibility of dry matter, and crude protein in AC and charcoal diets tended to incraese. However, any tendency in ruminal degradation of crude fat was not observed. Ruminal degradation of NDF in AC diets tended to be more increased than that in non-AC diet. Although it was not significant, ADF tended to be increased in AC and charcoal diets. AC and charcoal did not affect the ruminal pH and ammonia-N. Concentration of total VFA and butyrate tended to be increased by adding AC and charcoal(p<0.05). Although it was not significant, acetate/propionate ratio tended to decreased in AC and charcoal diets. Although there appeared some beneficial effects in adding AC and charcoal to ruminant diets in this study, more works could be needed with AC before we can make clear conclusion on use of AC and charcoal in the ruminant diets.

An adoption of high-speed railway due to the increments of traffic and the requirements of high-speed transit is essential business for the future transportation system and road. However, it is expected that the high-speed railway will cause much annoyance to the residents living in the vicinity of the high-speed railway. In this study, the domestic and foreign criterions for the high-speed railway noise were investigated with the basis of the analysis of existing data and a field survey of noise condition nearby high-speed railways. There are limitations to control the expanding noise over the boundary by general noise barriers. Accordingly, it is not effective to attenuate the noise in residential area with the noise of high intensity. The primary object of the study is to provide useful data for the design of noise barrier in residential area nearby high-speed railway. A number of field measurement to various noise barriers were carried out. Based on the results, fundamental data were provided to design the noise barrier propels.

강릉시 시범 공설묘지 조성사업은 경사 30˚ 의 표고차가 심한 산지를 절 · 성토하여 계단식 묘역단을 조성하는 공사로 수직고 15m이상의 대절토 및 성토부가 산재하고 있다. 특히 묘역단장후 주변 유입수 및 표면 유출수에 의한 비탈면 붕괴, 묘역단 유실 등의 피해가 발생할 경우 보수 또는 보강이 사실상 어려운 실정이며, 사회적 여론으로 확대될 가능성이 크므로 비탈면 보호에 필요한 녹화공법을 검토하였다. 구체적인 연구내용으로는 설계도면 및 현장답사를 통한 문제 비탈면 추출, 비탈면의 물리적 특성과 식생의 생육상황 파악, 비탈면 주변부의 식생조사와 유용식생 선발, 비탈면의 토양조건 분석 및 비탈면 토사의 기본물성 조사 등이며, 이를 기초로 하여 비탈면 현황 및 문제점을 파악하고, 그 대안을 제시하였다. The construction of a public cemetery in Kangnung city includes terraced graveyard with cutting or banking in mountain which has severe altitude differences with a slope of 30˚. Therefore, there are scattered cutting and banking sections with vertical height more than 15m. Especially, if the slope failure or the loss of a graveyard happens after graveyard establishment due to surface flow and inflow around, it is difficult to repair, causing serious public censure. Accordingly. revegetation works were examined that need protection of slope. The specific content of the study was the selection of slopes requiring special care through blueprint and field investigation the measurement of the physical property of slope and the situation of vegetative growth, the investigation of vegetation in slopes and the selection of vegetation, and the analysis of soil condition of slopes and the physical condition of slope sediment. On the basis of investigations some alternatives were proposed.Key words: public cemetery, slope protection works, revegetation works

This study aims at providing useful data for the design of underground stations through an extensive survey of acoustic properties in underground stations in Seoul. In order to improve the sound efficiency at the underground station, sound characteristics in the space of the underground station were studied. Architectural features of underground stations located in Seoul were examined by visiting every site and analyzing drawings. The distinction in architectural features of this study resulted in the line-side section, the shape of under-platform section and ceiling material. Number of underground stations was selected and categorized based on architectural features, such as line-side section, the shape of platform section and ceiling material. Each selected station was revisited and the noise levels were measured and compared with the architectural features. The study found that the Sum-Sik type is more efficient than the one of the Sang-Dae-Sik type, which can be used for subway stations. The semi-circular section for the railway-side seems to contribute on the attenuation of noise transmitting from trains to the platform. In addition, the aluminum absorbing panel, net luber and zinc plate (panel 40% and net 60%) as ceiling meterial are more efficient than the horizontal aluminum spendral panel, vertical aluminum spendral panel with line and zinc plate (panel 40% and net 60%), respectively.
