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.

홍성락,고정대,김순희 濟州大學校 基礎科學硏究所 1994 基礎科學硏究 Vol.7 No.1

제주도 전 지역의 특정위치를 선정하여 그 위치에 따라 지하 60m, 61m, 87m, 99.5m, 220m까지 깊이별로 화산암 시료를 채취하여, 이 시료에 대한 SIMS, XPS와 Mossbauer spectroscopy의 실험결과를 보고한다. UHV chamber에서 분리 이온화에 의해 생겨 난 parent 이온들로부터 cracking pattern들에 대해 연구하였고, 그 parent 이온들은 Si??, Al??, Ca??, Mg??, Fe??, Fe??, Na?, k?등으로 나타났다. 이 시료들에 대한 XPS 실험에서 wide scan analysis를 통하여 시료 표면에서 Al, Si, Ca, O, Fe, Na 등의 원소가 존재하고 있음을 알 수 있었으며, narrow scan analysis를 통하여 이들 대부분이 single compound state를 나타내고 있음을 발견할 수 있었다. 화산암에 대한 Mossbauer spectrum으로부터 olivine, pyroxene, ilmenite에 의한 세쌍의 quadrupole splitting을 얻었으며, 각 광물에 함유된 Fe는 약간의 Fe??를 제외하고는 거의 모두 Fe??상태임을 확인하였다. We are reporting the results of measurements of the SIMS, XPS, and ??Fe Mossbauer spectrum for powder samples of volcanic rock which has been distributed throughout different areas on Cheju island, each in different depth beginning at 60m then 61m than 61m, 87m, 99.5m, and 220m. We have studied the cracking patterns from parent ions which are created by dissociative ionization in the UHV chamber. The parent ions were Si??, Al??, Ca??, Mg??, Fe??, Fe??, Na??, and k??. In the XPS results for these samples, we find the existence of elements Al, Si, Ca, O, Fe, Na on their surfaces through the wide scan analysis. Also, the single compound state has appeared in a greater percentage of the them through the narrow scan analysis. The Mossbauer spectrum consists of well defined quadrupole doublets having a dominant 2+ charge state with a small percent having a 3+ charge state. These indicate the presense of olivine, pyroxene, and ilmenite.

8 비트 MPU 기반의 Web-RTU의 설계 및 구현

홍순필,김은성 순천향대학교 부설 산업기술연구소 2004 순천향 산업기술연구소논문집 Vol.10 No.2

In SCADA system, n RTU is a device installed at a remote location, that collects data, codes the data into a format that is transmittable and transmits the data back to a central station, or MTU. An RTU also collects information from the master device and implements processes that are directed by the master device. RTUs are equipped with input channels for sensing or metering, output channels for control, indication or alarms and a network port, In general, the data are transmitted via a wired network infrastructure such as RS422 or RS485 between RTU and MTU. But, the system suffers from covering remote areas due a limited range of the wired network, and building a wired communication network is not easy in the circumstances. In this paper, we design and implement a smart cost-effective Web-RTU that can communicate with MTU via Web. Web is of benefit to the Web-RTU,because it is not only free from the distance limitations but also is built easily and cost-effectively wherever Internet resources are available. Additionally, Web can be easily applied to the SCADA system with the development of hardware and software for communications. The Web-RTU has a program memory, a data memory and a RAM inside, and uses Atmega128, low-cost 8 bit micro-processor with eight AI(Analog Input). It performs well enough to implement all existing roles of RTU.

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.

펜아실 벤젠슬포네이트와 벤질아민의 친핵성 치환반응에 관한 연구

홍성완,박도순 又石大學校 1992 論文集 Vol.14 No.-

The nucleophilic substitution reaction of phenacyl benzenesulfonates(PBS) with benzylamine(BA) in methanol have been studied by conductometric method. The transition state structure for the reaction is investigated using various selectivity parameters, especially with cross interaction constants, ρ_ij β_ij The magnitudes of ρ_ij indicated that in the transition state bond breaking had progressed very little, but bond formation was substantial. The trends in reactivity were similar to aniline series, but the TS was found to be somewhat looser than that for aniline series. It was found that reactivity-selectivity principle(RSP) and Bell-Evans-Polanyi principle (BEP) hold within the BA series and hence constituted a good example of a thermodynamically controlled reaction series but are violated between two different reaction series with BA and aniline.

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.

Bacillus licheniformis에 의한 Alkaline Phosphatase의 生成 및 그 酸素의 特性

洪淳德,河相哲 慶北大學校 1984 論文集 Vol.37 No.-

Optimum culture condition of Bacillus licheniformis for the production of alkaline phosphatase and some properties of the partially purified enzyme were investigated. The production of alkaline phosphatase was at best when the culture medium contained 0.2% fructose, 1.5% neopeptone, 0.2% (NH_4)_2SO_4, 0.2mM K_3PO_4, and 10mM MgCl_2 at a initial pH of 9.0. The enzyme was purivied by ammonium sullfate fractionation and DEAE-cellulose chromatography. The specific activity at the partially purified enzyme was 250 times higher than that of the crude extract and the yield was 10%. The enzyme showed a optium pH of 9.0 and was stable in the range of 8.0-9.5. It had a optimum temperature of 60℃ and was also thermostable retaining 85% of it's activity when exposed to 60℃ for 30 min. The enzyme activity was promoted in the presence of Mg^++ and Co^++ but inhibited in the presence of Hg^++. Km value of the enzyme was determined to 0.1 mM with p-nitrophenylphosphate at pH 9.0

홍영숙,성낙응,경난호,이순남 梨花女子大學校 醫科大學 醫科學硏究所 1984 EMJ (Ewha medical journal) Vol.7 No.3

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.

洪淳德,金鐘國,李東善,河相哲,李相瀚,李載蘭,安賢淑 慶北大學校 1991 論文集 Vol.51 No.-

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.
