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.

<P>In the course of searching for bioactive secondary metabolites from marine fungi, TMC-256C1 was isolated from an ethyl acetate extract of the marine-derived fungus <I>Aspergillus</I> sp. SF6354. TMC-256C1 displayed anti-neuroinflammatory effect in BV2 microglial cells induced by lipopolysaccharides (LPS) as well as neuroprotective effect against glutamate-stimulated neurotoxicity in mouse hippocampal HT22 cells. TMC-256C1 was shown to develop a cellular resistance to oxidative damage caused by glutamate-induced cytotoxicity and reactive oxygen species (ROS) generation in HT22 cells, and suppress the inflammation process in LPS-stimulated BV2 cells. Furthermore, the neuroprotective and anti-neuroinflammatory activities of TMC-256C1 were associated with upregulated expression of heme oxygenase (HO)-1 and nuclear translocation of nuclear factor-E2-related factor 2 (Nrf2) in HT22 and BV2 cells. We also found that TMC-256C1 activated p38 mitogen-activated protein kinases (MAPK) and phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathways in HT22 and BV2 cells. These results demonstrated that TMC-256C1 activates HO-1 protein expression, probably by increasing nuclear Nrf2 levels via the activation of the p38 MAPK and PI3K/Akt pathways.</P>

LANDSTAT 자료를 이용한 유출곡선지수의 추정

조홍제,황재호 울산대학교 2001 공학연구논문집 Vol.32 No.1

수치고도모델을 이용하여 유역의 지형학적 특성을 분석하고, LANDSAT 위성영상을 이용하여 유역의 토지피복상태를 분류한 후 유출곡선지수를 추정하였다. 특히, 우리나라는 유역의 대부분을 산림이 차지하는 피복특성이 있으므로 식생의 다중반사특성을 응용하여 산림지역을 분류하고 유출곡선지수 추정에 응용하였다. 산림지역은 식생의 건강 상태나 밀도에 따라 유출특성이 변화하는데, LANDSAT 위성영상의 다중분광자료를 사용하여 산출한 식생지수는 산림지역을 밀도나 건강상태에 따라 분류하는데 유용하였다. 또한 식생지수를 사용하여 산림지역을 분류한 후 산출한 유출곡선지수는 산림지역을 분류한 후 산출한 유출곡선지수에 비하여 감소하는 것을 확인할 수 있었다. Having analyzed the topographical quality of the basin using Digital Elevation Model and classified land uses by LANDSAT Satellite image, we estimated Runoff Curve Numbers. Most of the basins are characterized by the forest, therefore multiple reflex qualities were used to classify the forest and to estimate Runoff Curve Numbers. Because runoff changes according to the vegetative health and density, the vegetation index derived from the multispectral data of LANDSAT satellite images was useful to classify the forest by its health and density. It was observed that Runoff Curve Number decreased when the vegetation index was taken into account. In conclusion, the mulispectal image was useful to observe special quality and classification of the land.

Polyesteramide(PEA) was prepared by the polymerization of caprolactam and 6-amino-caproic acid with oligomer of polyethylene terephthalate, which was prepared by the reaction of terephthalic acid with ethylene glycol, and characterized by melting point, molecular weight and whiteness. The results are summarized as follows. (1) Molecular weight has no relation to melting point of PEA. (2) Molar fraction of caprolactam of stoichemistry has no relation to molecular weight of PEA. (3) Melting point of PEA decreased with the molar fraction of oligoester of stoichiometry and was still lower than that of polyethylene terephthalate. (4) Whiteness of PEA decreased with the molar fraction of oligoester of stoichiometry and superior to that of PEA from hexamethylenediamine and oligoester, in respect of whiteness.

二重 Silicon Gate NMOS 工程을 利用한 2K EPROM 製作 및 測定

조협제,정호선,이덕동 경북대학교 공과대학 1986 工大硏究誌 Vol.15 No.-

2K bit EPROM array and test patterns were fabricated by double poly silicon-gate NMOS technicue. The channel length and width of the EPROM cell were 6㎛ and 12㎛, respectively. The operation of peripheral circuits was simulated by SPICE and the expected results were compared with experimental results. The optimal conditions of cell for programming were the drain voltage of 15-17V, gate voltage of 19-21V and the width of programming pulse of 30-35㎳, respectively. At that time, the threshold voltage was shifted from 1.6V(in erased state) to 9.4V (in programmed state).

Background : Emphysematous pyelonephritis (EPN) is an acute gas forming necrotizing infection of the renal parenchyma with high mortality. Although its incidence is relatively low, it mostly occurs in patients wiith diabetes mellitus. The aim of the study is to identify the risk factors related to mortality and assess the outcome of managements according to the radiologic classification. Materials and Methods : The clinical records of 23 patients diagnosed with EPN were reviewed retrospectively. The cases were grouped into two types on the basis of computed tomography scan. Type 1 EPN was defined as renal necrosis and gas formation with total absence of fluid content. Type 2 EPN was defined as the presence of renal or perirenal fluid in association with bubbly or loculated gas pattern. The patients' symptoms, performed investigations, and treatments were analyzed. Results : All patients had diabetes mellitus. Escherichia coli (78.6%) was the most common pathoqen in urine and blood cultures. The factors showing statistically significant differences between survivors and non-survivors were age (P=0.013), the presence of obstructive uropathy (P= 0.008), and type 1 group (P=0.030). Multivariate logistic regression showed that factor significantly related to death was age (odds ratio=1.20, 95% confidence interval 1.01-1.38, P=0.037). Conservative treatment including antibiotics and percutaneous drainage was successful in type 2 group, Overall mortality was 26.1%; all expired patients were from type 1 group. The mortality of conservative treatment and nephrectomy in type 1 group was 83.3% and 20.0%, respectively. Conclusion : These results suggest that old age is a significant risk factor for mortality in patients with EPN. Nephrectomy should be considered as the main treatment option in patients with type 1 EPN.

The objective of this study is to analyze the performance evaluation of the Radiant Floor Cooling and the dehumidification system included in the integrated system may be utilized as a supplementary cooling device through field experiments. The experiments are performed to evaluate the performance of the radiant floor cooling and confirm the possibility of continuous cooling through the actual field experiments, moreover, analyze specific characters of the radiant floor cooling system according to varying the load conditions which is able to happen to field. Experiment results show that the permissible ambient temperature range was determined by cooling load calculations, and the cooling capacity was calculated from steady-state heat transfer equations. Under these conditions, experiments were performed for an actual apartment building assuming two occupants. During 80% of the cooling period, radiant floor cooling provides sufficient and continuous cooling. The results of analyzing the indoor thermal environment in the actual apartment building show that the set room air temperature is maintained while the floor surface temperature, vertical temperature distribution and PMV remain within the comfort range.

Greedy 알고리즘을 이용한 라이브러리 맵핑에 관한 연구

조남경,김재진,음호식 공주영상정보대학 1999 논문집 Vol.6 No.-

본 논문은 원천 컴포넌트의 기능보다 목표 컴포넌트의 기능이 적을 경우 목표 컴포넌트로 동일한 기능을 수행하는 Greedy 알고리즘을 제안하였다. Greedy 알고리즘은 각 컴포넌트의 함수를 비교하여 목표 컴포넌트에 부족한 기능을 수행할 수 있는 잉여 로직을 추가하여 맵핑하는 알고리즘이다. 예제로 선정한 원천 ALU는 3개의 산술기능을 갖고있고 목표 ALU는 2개의 산술기능을 갖고 있는 컴포넌트이다. 본 논문의 Greedy 알고리즘을 이용하여 동일한 기능을 수행하기 위하여 맵핑된 결과 2×1 MUX 1개와 인버터 1개가 추가되어 동일한 기능을 수행하였다. 따라서 실제의 시스템을 구현할 때 CAD 물상에서 라이브러리가 제공되지 않을 경우, 본 논문에서 제안한 HLLM 기술을 이용하여 기본적으로 제공되는 라이브러리를 이용하여 동일한 기능을 수행할 수 있었다.
