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.

김명수,박제현,하헌주,허규하,서지연,김유선,김혜진,박기일 이화여자대학교 약학연구소 2004 藥學硏究論文集 Vol.- No.14

Background: Excess proliferation and extracellular matrix (ECM) accumulation of mesenchymal cells such as vascular smooth muscle cells (VSMC) and glomerular mesangial cells cause chronic allograft nephropathy showing transplant vascular sclerosis and glomerulosclerosis. Mycophenolic acid (MPA) and rapamycin (RPM) are well known as strong inhibitors of VSMC proliferation, but their effects on the glomerular mesangial cells are not yet clearly understood. This study examined the effects of MPA or RPM on PDGF-induced proliferation and ECM accumulation in rat glomerular mesangial cells. Methods: Mesangial cells isolated from the glomeruli of Sprague-Dawley rats were cultured with DMEM containing 20% fetal bovine serum. Growth arrested and synchronized cells were administered with test drugs (MPA10 nM-10μM, RPM 0.1 nM-1μM) before the addition of PDGF 10 ng/mL. Cell proliferation was assessed by [³H]thymidine incorporation, collagen by [³H]proline incorporation, and fibronectin, ERK, and p38 MAPK by Western blot analysis. Results: PDGF increased mesangial cell proliferation by 4.64-fold. Compared to stimulated control, MPA above 500 nM and RPM above 10nM showed a significant inhibitory effect in a dose-dependent manner. The IC_(50) of MPA and RPM against PDGF-induced mesangial cell proliferation were around 500 nM and 100 nM, respectively. The collagen synthesis was also inhibited by MPA and RPM, but the fibronectin secretion was inhibited by MPA alone. The proliferation of mesangial cell correlated with activation of ERK and. p38 MAPK. MPA, but not RPM, inhibited ERK and p38 MAPK activation. Conclusion: This study demonstrated that MPA and RPM significantly inhibited PDGF-induced proliferation and ECM production in rat glomerular mesangial cells. The inhibitory effects of MPA, but not RPM, are correlated with ERK and p38 MAPK.

고지 재사용이 제지공장 폐수에 미치는 영향에 관한 연구 : 판지공장을 중심으로

김혜태,주충열,최규석 漢陽大學校環境科學硏究所 1987 環境科學論文集 Vol.8 No.-

제지의 원료로서 고지들이 virgin pulp에 비해 얼마나 많은 오염부하를 폐수에 미치며, 화학적, 생물학적 처리효율은 어떤가를 파악하기 위하여 오염도를 각 원료 1 ton당 BOD, COD, SS의 kg양으로 나타내었다. 이는 초지조건, 즉 용수사용량, 고지혼입률 등의 차이에도 오염부하량을 산정할 수 있도록 하는 한편, 최적처리조건을 도출하는데도 이용할 수 있다. 실험은 KS규격에 의해서 각 시료들의 수초지를 제조하여 그 초지백수를 원폐수로 하고 jar tester상에서 alum을 가하여 응집침전시킨 후 상층액을 화학적 응집침전처리수로 하였으며, 역시 원폐수를 일정시간 폭기시켜 방치한 후 상층액을 생화학적 활성오니처리수로 하였다. 본 실험에 의한 각 고지의 제지폐수의 특성은 virgin pulp에 비해 매우 높게 나타났는데 그 결과는 다음과 같다. 첫째로 원폐수에서는 TCOD(kg-COD/ton-p)가 AOMG (41.1)>KONP(29.2)>AONP (24.6)>AOCC(24.2)>LUKP(5.9)>NBKP(2.8)순이며, TBOD(kg-BOD/ton-p)는 AOMG (22.5)>AOCC(20.1)>KONP(18.3)>AONP(16.1)>LUKP(5.1)>NBKP(2.5)순이며, SS(kg-SS/ton-p)는 AOMG(151.4)<KONP(50.0)>AONP(39.4)>AOCC(37.3)>LUKP (19.0)>NBKP(18.2)순이었다. 둘째로 화학적 응집침전처리에서 TCOD는 alum농도 100,400mg/l에서 peak cut가 일어났다. 셋째로 생물학적 활성오니처리에서는 폭기 4시간만에 AOMG를 제외하고 70%이상의 TBOD감소율을 보였다. 마지막으로 화분의 거동은 고지와 virgin pulp 사이에 뚜렷한 패턴의 구별을 보이지 않았다. When old papers are reused as the raw meterial for paper manufacturing, water and raw material come into contact directly in the process of paper manufacturing and fine fiber and all kinds of pollution elements of old papers get discharged with the waste water, thus increasing the load of pollution of paper manufacturing factory. This research is designed to measure the degree of pollution characteristics of old papers compared to virgin pulps. In order to obtain the outcome of optimum treatment condition, the unit of BOD, COD, SS is expressed in kg per ton of each raw material. The characteristics of waste water of each old paper obtained through this experiment are higher than those of waste water of virgin pulp and the following is the results. 1. In case of original influent (1) TCOD(kg-COD/ton-p) AOMG 41.1>KONP 29.2>AONP 24.6>AOCC 24.2>LUKP 5.9>NBKP 2.8 (2) TBOD(kg-BOD/ton-p) AOMG 22.5>AOCC 20.1>KONP 18.3>AONP 16.1>LUKP 5.1>NBKP 2.5 (3) SS(kg-SS/ton-p) AOMG 151.4>KONP 50.0>AONP 39.4>AOCC 37.3>LUKP 19.0>NBKP 18.2 2. In case of chemically treated effluent (1) As for TCOD, when concentration of alum is 100,400mg/l, the peak cut has occured (2) As for SS, when concentration of alum 100mg/l, the peak cut has occured. (3) Even up to 800mg/l concentration of alum, residual TCOD(kg-COD/ton-p) of effluents has shown AOMG 8.8>AOCC 4.6>AONP 3.9>KONP 3.8>LUKP=LBKP 1.2 3. In case of biochemically treated effluent (1) After 4 hours of aeration, except the effluent of AOMG, all kinds of effluents have shown over 70% decrease of TBOD. (2) Even up to 8 hours aeration, residual TBOD(kg-BOD/ton-p) has shown AOMG 4.8>KONP 2.9>AONP 2.7>AOCC 1.7>LUKP 1.0 4. There was no special pattern of the behavior of ash among the old papers and virgin pulps.

In this study, theoretical analysis and finite element analysis of the behavior of membrane (such as resonance frequency, membrane deflection, collapse deflection and collapse voltage)in thc capacitive micromachined ultrasonic transducer (cMUT) were performed. The design parameters of the cMUT were estimated and are the dimension and thickness of membrane, thickness of sacrificial layer, thickness and size of electrode, size of active element and so on. The resonance frequency of the membrane increased as the thickness of the membrane increased but decreased as the diameter of the membrane increased. The deflection of the membrane increased as d-c bias voltage increased. The collapse voltage of the membrane was predicted.

By electrochemical oxidation remaining pesticides treatment of recovered pesticide bottle wastes were oxidized and decomposed in a particle packed-bed electrode cell that it was increasing in an anodic reaction area by the proper packing materials. Air flotation oxidation treatment was used to compare organic oxidation by oxygen being generated at the anode with organic oxidation by electrolysis. Obtained the data from the results of batch style particle packed-bed electrode cell were applied to flow style and investigated necessary the some parameters to treat the remaining pesticides wastewater of recovered pesticide bottle wastes. At the removal COD of remaining pesticides wastewater of recovered pesticide bottle wastes PbO₂ was the best anode packing particle and optimum current condition was 3.33A/dm² at the batch style cell. When this condition was applied continuous flow style, the current was 0.69A/dm² at the 30 ml/min flow rate. Also incase of circulation COD was more decreased than not. Removal COD appeared a good tendency, when not only NaCl was added into the wastewater, but also wastewater was a high temperature. At performance comparison of reactor type rectangle type appeared a good tendency and special per-treatment of wastewater was unnecessary. Degradation of TOC was about 70% and COD was obtained about 92% after 85min, when this experiment were carried out electrolysis condition of 0.69A/dm², current density, and 30ml/min, flow rate.
