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.

Kinetic studies of nucleophilic substitution reactions of substituted benzenesulfonyl chlorides with substituted N,N-dimethylanilines were conducted at 35.0℃ in methanol. Results showed that (ⅰ) the magnitude of ρ_X and β_X associated with a change of substitutent in the nucleophile are large and indicate a relatively advanced bond-formation in the transition state, (ⅱ) The large negative cross-interaction constant. ρ_(XY) = -0.53. These values show that aminolysis of benzenesulfonyl chlorides proceeds by S_N2 mechanism with some S_N2 -S_AN border reaction.

This study was carried out to investigate the characteristics of mulberry fruit seolgidduk. Four percent additions of mulberry were evaluated as the most suitable concentration for seolgidduk, in order to improve the color of gum metal gray and sour smell. Therefore, in order to improve the preference, citric acid was added. The acidity of mulberry fruit seolgidduk increased and its pH decreased significantly by increasing amount of citric acid. The moisture content of mulberry fruit seolgidduk showed no significant difference between the groups with added citric acid and the control of group. The L value decreased as the citric acid concentration increased. Color a and b (Ed-define 'a' and 'b') values increased significantly by increasing the amount of citric acid. The hardness, cohesiveness, springiness, gumminess and brittleness decreased as the citric acid was added. From the sensory evaluation, mulberry fruit seolgidduk with 0.01% citric acid added was the most preferred in taste, chewiness and overall acceptability. These results indicated that mulberry fruit seologidduk with 0.01% citric acid added showed the best quality.

E-Commerce is one of the most competitive industries internationally. From the perspectives of the industrial policies, it is necessary to prepare taxation policies to activate E-Commerce in our country since it is high value-added industry in the future. This study reviews the international discussion, and taxation system that lead to economic and social changes and suggests future directions to prepare rational taxation after reviewing taxation problems based on value-added tax which has influence on international tax revenue allocation.
Phytochrome이 보리잎 Protoplast의 팽윤에 미치는 영향
홍경애,송성준,송필순,유장걸,문두길 제주대학교 방사능이용연구소 1986 연구보고 Vol.2 No.-
암조건에서 생육시킨 보리(Hordeum valgare)잎의 생장점 부근에서 분리한 Protoplast가 적색광 처리에 의해서 팽윤되었고 적외선광에 의해서는 적색광 효과과 소멸되었다. 이 사실은 Protoplast의 팽윤이 Phytochrome에 의해서 조절됨을 시사하는 것이나 Phytochrome의 작용기작을 알기 위해서는 다각적인 연구가 필요하다. 실험결과로 부터 적색광 처리시간은 2분 적색광 처리후 배양시간은 2시간이 적당함을 알았다. Protoplast 배양액의 Sorbitol 농도에 따른 크기변화는 농도가 낮을수록 커졌으며 0.4M 이하에서는 Protoplast가 파괴되었다. Light effect on the size of protoplasts isolated from etiolated barley leaves was studied. Red light irradiation caused a swelling of protoplasts while little change in size found under the dark condition. Photoreversibility by red light and far-red light was found in protoplast swelling, indicating the involvement of phytochrome. Action mechanism of phytochrome on protoplast swelling should be clarified in aspect of growth regulators and intermediates involved. Two minute irradiation time and two hour incubation after red light treatment were found sufficient to induce protoplast swelling. The protoplasts were swollen according to the sorbitol concentration of incubation media but destroyed below 0.4M-sorbitol concentration.

문화재란 문화가치가 있는 사물로서 국가 가 종교적·세속적 근거에 따라 특별히 지정 한 재산이다. 문화재는 그것이 구현하는 정신적 가치와 시각적 음향적으로 표현하는 수단으로서 그 나라의 독특하고, 다양한 주체성을 보존하는 중요한 매체이기도 하다. 그러므로 문화재는 한나라의 민족역사와 문화로서 과거의 모습을 통해 현재 그리고 나아가 미래를 연결시키는 하나의 매개체인 것이다. 또한 문화재는 그 지역민에게 향토사적 인 자긍심 및 연대의식을 고취시키는 동시에 나아가 한 나라, 세계적인 관심사로 여겨 야 할 것이다. 원적산 봉수대는 양산군청 소재지에서 북쪽으로 약 9.2㎞, 통도사입구 마을인 신평에서 남쪽으로 8㎞지점에 있다. 이 봉수대는 경상남도 기념물 제 118호로써 원적산봉수대 보존회에 의해 복원된 문화재이다. 즉 다른 지역의 문화재와 달리 잊혀 져가는 문화재의 재생을 통해 다시 태어난 문화재인 것이다. 원적산 봉수대 주변정비 기본계획의 목적 은 지역민의 자긍심으로 복원된 봉수대와 주 변과 접근로를 체계적으로 정비를 함으로써 접근성, 전통성, 보존성을 높이고자 한다. 특히, 문화재보호를 위한 제반 법규 및 현지여건에 부합하는 정비방향을 설정하고, 전문 인력과 관련문헌을 바탕으로 문화재 주변을 역사성과 주민친화성, 기능성, 관광성을 함께 갖춘 문화공간으로서의 미래지향적 문화재정비 계획을 추구하고자 한다.

In order to isolate selectively sisomicin over-producers during mutagenesis, several conditions required for fragmentation, mutagen treatment, and selection of mutants were examined. As a result, up to 30% yield-up of the antibiotic production of a candidate was achieved. For the step of scale-up, effect of antifoaming agent in small scale with flasks was studied. Palm oil was very effective within the range of without inhibiting of growth. Water addition during the fermentation enhanced 10% of sisomicin productivity than that of control.

Lipoprotein cholesterol and triglyceride levels have been determined innormal and diabetes. The abnormalities of lipoprotein were investigated by SDS-polyacrylamide gel electrophoresis in the serum and the 3 major lipoprotein classes for diabetes. HDL cholesterol levels were lower in the diabetes compared to the normals. VLDL triglyceride levels also elevated in the diabetes. There were significant shifts in the distribution of lipoprotein cholesterol, with an increase in LDL cholesterol and decrease in HDL cholesterol. The results of this study suggest that diabetes may be associated with changes in both lipoprotein triglyceride and cholesterol levels. The electrohoretic patterns of VLDL and HDL in diabetes showed the abnorm-al pattern in comparison to normal.

In order to screen the new β-lactam antibiotics for clinical use. we were compared MIC values of various β-lactam antibiotics. We also tested the influence of pH, inoculum size, stability of antibiotics in medium and some kinds of media on MIC value. As a result, cefotaxime, cefoperazone, piperacillin, cefamandole, cephaloridine, cephapirin, cefazolin, cephalothin, cephaioylycn were scored in antimicrobial activity of MIC data.
