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.

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.

국내외로부터 수집한 고추 유전자원을 포장에 재배하여 종자를 증식하는 동시에 주요 특성을 조사하였다. 헝가리에서 도입하여 1992년도에 평가한 계통들은 Hungarian Wax 혹은 Bell형으로서 바이러스에 심하게 걸려 우리포장환경에 잘 적응하지 못하였다. 1994년도에 평가한 계통들 중 브라질에서 풋마름병 저항성으로 도입한 KC350과 KC351은 직립성이며 바이러스에 강한 편이어서 매우 유망한 유전자원으로 사료되었다. 중국에서 도입한 KC376는 바이러스에 강한 편이며 대과를 착생하여 유망하게 보였다. 태국에서 도입된 계통들은 안동대에서 특성을 평가기록하였다. Accessions of pepper germplasm were planted in the field and their characteristics were recorded. Lines introduced from Hungary were very susceptible to virus diseases and as a result poor in adaptability in domestic field condition. KC350 and KC351 which were introduced from Brazil were growing errectly and tolerant to both bacterial spot and virus diseases. KC376, an introduction from China, was bearing large fruits with tolerance to virus. Introductions from Thailand were grown and evaluated in Andong Universiy, and major characters of them were recorded.

The stick antimony electrode has advantage of simplicity in measuring pH. Its field of application has been very wide in industrial and medical part. But its accuracy, sensitivity and reproducibility are somewhat poorer than those of glass electrode. In this study this electrode was applied in determining pH of the solution at various temperatures (15∼30℃) under high pressures (1∼2,500 bars). The emf(E) of the cell, Sb(Sb_2O_3/ HCl(aq.) /AgCl/ Ag, was messured and plotted against pH. In this plot standard emf(E°) of the cell was obtained by extrapolation. The relationship of emf(E) and pH at 25℃ under 1 bar was as follows, E=0.034+0.05918 pH. The slopes were decreased with increasing pressure, and emf(E) was increased. These phenomena may be caused to the activities of water, Cl^-, Sb_2, Sb_2O_3, Ag, and AgCl. In plot of pressure and pH the decrease of pH values was due to the increase of dissociation constant of hydrochoric acid. Even though the stick antimony electrode could be useful to 500 bars at 30℃, it could be useful to 1000 bars below 30℃.

Patient was sixty-eight years old female. She was transferred to our department to resect the solitary pulmonary nodule on right lower lobe. Intraoperative frozen-section revealed bronchioloalveolar carcinoma. So, we performed right lower lobectomy and mediastinal lymph node dissection. Permanent pathologic diagnosis of this patient was sclerosing hemangioma. We report experience of treatment of sclerosing hemagioma presenting solitary pulmonary nodule by lobectomy with the review of literatures.

Recently, as spreading of computer supplement and development of communication technology using network, the web users have rapidly increased in number on Internet environment. Then, new technology development to efficiently classify and retrieve this increasing information is necessarily required. In this paper, we propose a method of information classification with text-mining technique based on the document indexing method using representative keywords for efficient information retrieval. In the experimental results using total 1,200 Korean language articles of 4 categories, the proposed method shows average about 95% performance except information communication category in the classification rate.

MPEG-4 for an object base coding after extracting the region from image, the coding for a real-time requirements is quick and must be accurate. The object crisis algorithms of existing calculation quantity are many and with image transformation or video conferencing system to same real-time application they are not suitably. The object real-time tracking it tried to apply the CAM-Shift algorithm which is possible from the dissertation which it sees consequently. Tracking the object which it moves or wants the VO where (Video Object) tracking the user wants in bounding box form defines the object where is started. Tracking the object of after uses a CAM-Shift algorithm and are extracted and the VOP with the VO which it is composed. It defines one bounding box with the method which is proposed consequently about lower only one VOP there to be it will be able to compose, it becomes.

In Classified Vector Quantization(CVQ) for image coding, the block classification pondering the block characteristics will be the most important procedure if we consider system performance. But it does not take effect because classification of conventional CVQ followed act on a heuristic and statistics method. In order to solve the problem of conventional methods, i.e, for block classification effectively we propose a fuzzy inferencing algorithm to improve its performance. To do this, fuzzy rules must be generated in the first. Our rules are based on energy distribution in transform domain with respect to spatial variation. Ultimately fuzzy inferencing of this paper apply these fuzzy rules for efficient block classification on a input image. As a result of efficient classification, our proposed method shows that blocking effect is decreased and PSNR(peak to peak signal to noise ratio) is increased by about 1 ∼ 2 dB for 0.2 ∼ 0.6 bpp range, when the performance is compared with Aizawa's scheme^[9].
