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.

H.264 비디오 코딩 표준은 기존 비디오 코딩 표준에 비해 뛰어난 압축부호화 효율로 인해 차세대 비디오 표준으로 각광받고 있으며 H.264가 가진 잠재적인 영향력 때문에 오늘날 디지털 비디오 시스템의 주를 이루고 있는 MPEG-2 시스템을 대체할 것으로 보여진다. 현재 MPEG-2 시스템이 광범위하게 자리 잡고 있기 때문에 H.264 시스템으로의 완전한 이동은 다소 시간이 걸릴 것으로 예상되고, 따라서 트랜스코딩 기술이 중요하게 대두되고 있다. 트렌스코더는 디코더와 인코더를 포함한 구조이기 때문에 매우 많은 연산량이 요구되며 그 복잡도를 줄이는 것이 중요하다. 본 논문에서는 디코딩 과정에서 추출된 정보를 인코딩 과정에 재사용함으로써 복잡도를 줄이도록 하였고, 또한 H.264에서 연산량이 많은 부분들을 여러 가지 알고리즘을 통해 복잡도를 줄임으로써 보다 빠른 속도로 동작이 가능한 트랜스코더 구조를 제안하였다.

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.

This study is aimed to identify effects of import liberalization of chicken products not only on agriculture but also on national economy overall. The extending influences on production and income are generally measured using input-output analysis tool. But the reaction induced by import liberalization of chicken products would not be considered in the open static input-output-model, far example multiplicator effects between income and consumption. In order to overcome the defect of the open static input-output-model, the open static Leontief-model is extended to the income-consumption relation in measuring the extended effects of the import liberalization of chicken products. This study is undertaken using the results of KREI(Jan. 1994) which concluded that the direct losses in agriculture from 1995 to 2001 could be 113 billion won at the constant price of 1990. It was calculated that the indirect production losses of the other related industries could be 165 billion won, and 246 billion won in the view of income-consumption relation. It was also predicted that the indirect income losses of the other related industries would be 89 billion won, and 126 billion won in the view of income-consumption relation. As a result import liberalization of chicken products could possibly bring about larger losses to the other industries than to agriculture. Especially, in the "Other flood preparations" sector, the indirectly largest loses could predict to be occured.

The change of the microbial community structure in excess sludge of different sewage treatment plants by ozone treatment was investigated by quinone profiles. The resulting ozone dosage ranged from 0.1 to 0.4 gO₃/gTS. In terms of overall sludge reduction, more than 50% reduction of the total sludge mass could be achieved by ozone treatment at 0.4 gO₃/gTS. Quinone concentration and type in sludge of different treatment plants were remarkably decreases with increasing ozone dose. Ubiquinones(UQs)-8, -10 and MK-8 were still remained in the ozonized sludge at 0.4 gO₃/gTS. The results of this study showed that the remaining microorganisms belong to UQs-8, -10 and MK-8 were difficult to destruct cell membrane or wall by ozonation. Fecal Streptococci and Salmonella were not detected at ozone dose of 0.2 gO₃/gTS, but Fecal Colifom was not detected at ozone dose of 0.4 gO₃/gTS.

The LPC-10 speech data compression algorithm is implemented with computer program and invested through computer simulation. The simulation results show that the algorithm provides relatively good quality at the transmission rate of 2.4kbps. According to the investigation of the effect of channel errors on the algorithm in digital mobile radio communication, the algorithm has the good quality below the bit error rate of around 5×10^(-3).

This study was conducted to understand health status by general characteristic, and to find out relationship between the general characteristics and rural elderly's health status. Health status was measured using SF-36(Medical Outcome Study Short From 36). The finding of this study were as follow; Mean scores of health status by sex were higher in male on physical function, social function and role limitation-emotion. The elderly educated more reported good health on physical function, role limitation-physical, vitality, bodily pain and general health than did the elderly educated less. The elderly who have disease reported bad health on social function, mental health and general health. Therefore we reviewed the evidence that sex, education and illness are associated with health status in the elderly, and that specific public health service that related such condition should be considered for the rural elderly.

Kinetic studies of nucleophilic substitution reactions of phenacyl. benzeneslfonates(PBS) with N, N-dimethyl anilines(DMA) were conducted by conductometric method. Hammett and Broensted values were determined, in order to examine the transition state variations caused by changes in nucleophiles, substituents and indicated a relatively advanced bond-formation in the transition state. Application of potential energy surface(PES) and quantum mechanical(QM) models of transition state characterization lead us to conclude that the reaction proceeds via associative S_N2 mechanism. It was found that reactivity-selectivity principle(RSP) and Bell-Evans principle(BEP) held within the DMA series and hence constituted a good example of a thermodynamically controlled reaction series but are violated between two different reaction series with DMA and aniline.
