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.

황병훈,이준동,양경희,옥수석 한국광물학회 2004 광물과 암석 (J.Miner.Soc.Korea) Vol.17 No.4

경상분지 남동부에 분포하는 화강암질암은 야외산상 및 암석기재적 특징에 따라 크게 세 그룹으로 나눌 수가 있다. 즉, 그룹Ⅰ은 마그마혼합의 영향을 받은 암체로 염기성 미립 포유암 및 염기성광물 집합체를 다양하게 함유한다. 그룹Ⅱ는 낮은 압력하에서 형성된 천소관입암의 특징을 나타내며, 그룹Ⅲ은 A-형 화강암류의 특징을 보인다. 화강암질암의 광물학적 특징을 각 광물에 대하여 암상별로 살펴본 결과, 그룹에 따라 장석의 용리온토 및 흑운모의 성분 등에서 비교적 체계적인 성분변화를 보여주었다. 각섬석의 경우, 그룹Ⅰ의 암상들은 칼식-각섬석 영역에 속하며 각섬석 지압계에 의한 추정압력은 0.4~2.8 kb에 해당되었다. 그룹Ⅱ에서는 각섬석이 거의 산출되지 않았고, 그룹 Ⅲ의 각섬석은 알칼리-각섬석 영역의 리베카이트에 해당되었다. 흑운모의 화학조성은 비교적 그룹별로 군집을 잘 이루며, 그룹Ⅰ에서부터 그룹Ⅲ의 철질-앤나이트까지 연속적인 변화양상을 보여주었다. 사장석은 지역 및 암상별로 뚜렷한 차이를 나타내지 않으며, 대체로 알바이트, 올리고클레이스, 그리고 안데신의 영역에 해당된다. 그룹별로 퍼타이트 지온계에 의한 용리 온도를 검토한 결과, 그룹Ⅰ은 대체로 300~400℃ 정도이며, 그룹Ⅱ의 등립질화강암과 그룹Ⅲ의 알칼리장석화강암은 500~600℃ 정도로 높게 나타났다. Granitic rocks in the southeastern Gyeongsang. Basin can be classified into three groups. The group Ⅰ contains various mafic microgranular enclave (MME) and/or mafic clot which implies magma mixing or mingling. The group Ⅱ show the feature of shallow depth emplacement at low pressure, and the group Ⅲ is characterized by A-type granite implying extensional tectonic environment. Mineralogical characteristics of the granitic rocks have showed systematic variations in perthite exsolution temperatures and biotite compositions according to their rock facies, although they do not show any distinctively different trend in geography and textures or rock facies. Amphiboles from Group Ⅰ are calcic-amphibole and they were formed at 0.4~2.8 kb in pressure based on the amphibole geobarometry. Amphiboles from group Ⅲ are riebeckite, whileas amphiboles were not observed in Group Ⅱ The chemical composition of biotite defined in clusters showing a continuous spectrum between group Ⅰ to ferric-annite of group Ⅲ. The composition of plagioclase generally plotted in albite, oligoclase, and andesine area without any distinctive differences among their geography or rock facies. The exsolution temperatures by perthite geothermometry are calculated as 300~400℃ in Group Ⅰ, and 500~600℃ in equigranular granite of group Ⅱ and alkali-feldspar granite of group Ⅲ.

In the present study, the author investigated change of liver funtion in Viscum album lectin The lectin was purified by 0.15 M NaCl extraction, amnonium sulfate precipitation, sepharose 4B affinity chromatography and gel filtration using sephadex G-150 with plant material from Viscum album collected in Mt. Duk Yui. After 72 h of CCI, injection (in olive oil, 1:1, 2 mg/kg) there was a sig nificant increase in serum AST and ALT levels relative to the control group. However, treatment of either Viscum album extracts and purified lectin offered no protection against CC1,-induced hepatotoxicity. Histological observation basically supported the result obtained from serum enzyme assay. The livers of rats challenged with CCl. produced a marked increased cytoplasmic vacuoles and inflammatory cellsin num-ber, while the number of necrotic cells and swollen hepatocytes did not change significnatly. Rats administered olive oil alone did not alter the normal hepatic architecture. Histological observation of liver section in rat treated 72 h with either Viscum album extract and purified lectin CCl-induced liver damage showed number of cytoplasmic vaculoe and necrotic cell. The number of inflammatory cell increased markedly. The normal hepatic architectural pattern was lost in Hematoxylin-eosin stain. This results suggest to the conclusion that Viscum album lectin has a physiological effect of hepatotoxicity activator.

In case of an apartment house, the application of LC(Life Circle) design that considers remodeling and reconstruction when the a house reaches a certain time after its erection needs to be reviewed for longevity from time series life perspectives that set up a period of durability for components and maintains and improves their performances through systematic replacement and repair. Apartment houses are constructed with parts of different sizes and life. It is important to manufacture materials and components with high durability. However, more importantly, well-thought-out and systematic plans are needed between parts with a space module and a life module and construction space. Hence, this research sought to investigation of the expected service life of parts or members according to repair or replacement cycles with social and functional aspects, considering the establishment of housing parts hierarchy through the analysis of expected service life. Consequently, the establishment of the repair cycle and estimation of the service life of housing parts have the remodeling in place in the frontline construction business and cut cost on remodeling, thus activating remodeling.

변잠혈 검사에서 Guaiac법과 Latex법의 비교

장철수 ; 황석연 김천대학교 2010 김천대학교 논문집 Vol.21 No.-

There was concern about the false positivity of the popular guaiac-based test in fecal occult blood screening for the early detection of colorectal carcinoma. Recently the new immunological fecal occult blood test which was specific for humal hemoglobin was introduced. We evaluated guaiac, latex agglutination, and latex agglutination inhibition method. In senstivity study, guaiac and latex agglutination inhibition methods were positive above 1 mg/dl, latex agglutination method was positive above 0.1 w/dl. In specificity study, guaiac method was pos-itive to all seven animal hemoglobin, but two immunologic methods were opposit results. In the effect for temperature in stool collec-tion, converted to negative at 3-days in guaiac method, at 7-days in latex agglutination method, and at 14-days in latex agglutination inhibition method. In comparision study, the guaiac and immunolog ic positive rates were 35.0% and 9.0%. Most guaiac positive results were observed in unrelated gastrointestinal disorders. Guaiac method had been often false positive results, but immuno-logic fecal occult blood tests were excellent specific method for human hemoglobin methods showed similar positive rates.
