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.

Since the 1992 memorandum of Korea and China, Korea investment toward China has been greatly increasing and due to the economic, politic and culture interchange, numbers of Korean companies have been struggling with the difference of financial accounting standard system. This study is dealing with developing processing of two countries financial accounting standards, main differences and through actual comparison of two countries financial statement. Also, this case has been effectively done with the comparison of the actual financial statement users loan manager of bank and investment counselor of security corporation. Main results of this study is as follows; First, regarding the loan managers of banks, Koreans are more positive and better on reliability about the confirmed loan out and financial statement. Secondly, Korean investment counselors from security corporation are more positive and superior on investment decision making reliability than China. Thirdly, the most considerable factor that loan manager and investment counselor have are companies financial statement reliability. This is because accounting information users are evaluating reliability and loan managers are evaluating balance sheet & statement of income and investment counselors are considering the most about balance sheet and statement of appropriations of retained earnings. This study bas a purpose to understand Chinese financial accounting standards in China to Korean accountants by comparing both Korean financial accounting standards and Chinese financial accounting standards and moreover, to contribute to understand how Chinese financial accounting standards works and keep up. According to that reasons, this research carefully indicates following expectation. First, with expectation of research, we can assume that Chinas rapid development of her economy in accounting prospective and also, the difference between Koreans and Chinese accounting system by logical comparison and actual examples. Secondly, with expectation of actual job process, it is expected that more understanding between both countries financial accounting standards will rise.

To investigate the effect of thapsigargin(THP) and vanillylnonanamide(VN), derivative of capsaicin, on the ATP-induced ^45Ca-uptake in the sarcoplasmic reticulum(SR) of the skeletal muscle, the SR vesicles were prepared from the back muscle of the rabbit, and ^45Ca-uptake was carried out. The results as follows: ATP-induced ^45Ca-uptake of skeletal muscular SR was significantly increased by 1 mM ATP. It was significantly blocked by 5 μM THP, but slightly decreased by 20 μM VN. The combined effect of THP and VN on the 45Ca-uptake of the SR vesicles was much potentiated than the sum of each effect of them. The above results suggest that the action of VN, being slightly influential to ATP-induced Ca-uptake but potentiating the effect of THP on the Ca-uptake, might be related with direct perturbation of the SR membrane or exposure of the THP-binding site.

황재경,김홍규,공희상,윤효중,황용하,이기영,정연실,이성광,박혜영,김갑환,최원철,강문호 대한비만학회 2002 The Korean journal of obesity Vol.11 No.4

연구배경 : 일반인들의 비만에 대한 자가평가는 객관적인 기준에 의하기보다는 주관적인 것으로, 이는 체중조절에 대한 부적절한 노력을 이끌 가능성이 있다. 본 연구는 우리나라 성인을 대항으로 비만에 대한 자가평가와 체질량지수를 기준으로 정의한 객관적인 비만도 사이의 차이를 알아보고, 비만에 대한 인식에 영향을 주는 사회환경적 요인을 규명해 보고자 하였다. 방법 : 가천의대 길병원의 건강증진 센터에 내원하여, 건강검진을 받은 561명 (남 341 : 여 220) 의 성인을 대상으로 하였다. 체질량지수 20미만, 20 ~ 24.9, 25 ~ 29.9, 30이상 (kg/㎡)에 따라 네 군으로 분류하였고, 설문조사 상 자신의 체형에 대한 인식 (마른 편, 적당, 비만, 매우비만)과의 일치도를 살펴보았다. 결과 : 대상자의 연령은 37±13세, 남녀 비는 1.5:1, 체질량지수는 22.7±3.2 kg/㎡, 복부-둔부 둘레비는 0.85±0.07이었다. 체질량지수 (20미만, 20 ~ 24.9, 25 ~29.9. 30이상 (kg/㎡))를 기준으로 한 경우와 자가평가 (마른편, 적당, 비만, 매우 비만)에 대한 일치도는 각각 56%, 52%, 49% 그리고 89% (kappa=0.26)이었다. 그리고 , 체질량수 25 kg/㎡ 이상인 비만인 남성의 44%가 자신을 비만하지 않다고 평가하고 있었으며, 체질량지수 25 kg/㎡ 미만인 여성의 43%가 자신을 비만하다고 인식하였다. 비만에 대한 자가 평가가 적절한 군과 그렇지 않은 군 사이에 연령, 교육 수준, 거주지역 등에 의미 있는 차이는 관찰되지 않았다. 결론 : 우리 나라 성인에서 객관적인 비만도와 일반인의 자가 평가 사이에는 상당한 차이가 있다는 것을 알 수 있었다. 남성의 경우에는 자신의 비만에 대한 인식이 부족하였고, 여성의 경우에는 비만하지 않은 경우에도 자신을 비만하다고 과평가하는 비율이 높았다. 따라서, 일반인들을 객관적으로 비만 기준으로 정확히 평가하고, 올바른 신체이미지를 가질 수 있도록 교육하는 것이 필요함을 알 수 있었다. Background : Obesity has become a matter of great public concern in Korea with its increasing prevalence in recent years. People should properly recognize themselves whether to be obese or not before seeking medical attention. However self assessment of obesity may be erroneously subjective and misleading. This study is to investigate the possible discrepancy between self-assessment of obesity and obesity defined by BMI in Korean adults. Materials And Methods : Five hundred sixty one adult subjects (341 men and 220 women) who took a routine health examination in Gachon Health Center were included in this study. We analyzed the data obtained from health examination and a questionnaire including self-assessment of obesity categorized as underweight, normal, obese and severely obese. Body mass index (BMI) ≥ 25 kg/㎡ is defined as obese, BMI ≥ 30 kg/㎡ as very obese and BMI <20 kg/㎡ as underweight. Results : The age of the subjects was 37±13 years, male to female ratio 1.5:1, the BMI 22.7±3.2 kg/㎡, and the WHR 0.85±0.07. The concordance rates between self-assessment of obesity and obesity defined by BMI were 56%, 52%, 49% and 89% (kappa=0.26) respectively in underweight, normal, obese and very obese. 44% of men with obesity (BMI ≥25 kg/㎡) assessed themselves to be non-obese, whereas 43% of non-obese women (BMI ≥25 kg/㎡) assessed themselves to be obese. There were no differences in age, education level, and residential area between the groups who correctly assessed their obesity and did not. Conclusions : There were significant discrepancies between self-assessment of obesity and obesity defined by BMI in Korean adults. Significant proportion of men with obesity underestimated their obesity, while significant proportion of non-obese women overestimated their fatness. These results suggest that public education be required to provide the proper definition of obesity and avoid the misleading in its management.

This paper presents a new vibration control device by which the mass and damping of a structure is increased equivalently. The vibration control system, named toggle-rotational inertia-viscous damper, can be utilized effectively in applications of small structural drift. Numerical analysis shows that because the relative drift of a structure can be effectively amplified by the toggle system, the device has a great performance in the vibration control without the increase of the damper capacity and size. It is also observed that vibration control effects is caused by the increase of equivalent mass and damping due to the rotational inertia and damping of the device.

피부단순포진 진단을 위한 Tzanck 도말, 바이러스배양 및 면역형광검사의 비교 연구

黃道憲,金永泰,金在烘 한양대학교 의과대학 1991 한양의대 학술지 Vol.11 No.1

Although Herpes Simplex Virus (HSV) infection is one of the most common infectious diseases, its two main laboratory diagnostic methods-Tzanck smear is a simple, inexpensive and rapid method, but it shows relatively low positivity. Similarly, the viralculture is the most accurate and definitive method, but it is expensive and relatively time-consuming test. There is a demand for more practical laboratory diagnostic methods for cutaneous herpes simplex infections. The purpose of this study is to examine the effectiveness of the indirect immunofluorescence (IIF) staining with monoclonal antibodies, which is suggested as a practical method. For the study, 103 patients suspected HSV infection were sampled at the Department of Dermatology in Hanyang University Hospital from March 1987 to July 1990. In the 60 specimens for Tzanck smear and viral culture, Tzanck smear was 35(58.3%) positivities, and viral culture was 56(93.3%) positivities(p〈0.05). In the 43 specimens for viral culture and IIF staining, viral culture was 40(93%) positivities and IIF staining was 37(86%) positivities(p〉0.05). In the 25 specimens, which viral culture was positivities, IIF staining showed 22(88%) positivities and Tzanck smear was 16(64%) positivities(p〈0.05). In summary, the result of Tzanck smear showed relatively high correlation to the results of IIF staining and viral culture. However, the result of IIF staining showed a significant agreement with the result of viral culture. It is suggested that the IIF staining with monoclonal antibodies is a simple, inexpensive, but accurate and relatively rapid method for the diagnosis of cutaneous HSV infections.
