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.

여러가지 形式의 格子桁橋에 對한 應力의 自動解析

李淙錫,金聲得 울산대학교 1983 연구논문집 Vol.14 No.1

本論文의 目的은 格子桁橋의 設計에 있어서 Computer에 의한 새로운 방법이 紹介에 있다. 즉 지금까지도 格子桁橋에 쓰여지고 있는 Leonhardt, Homberg 方法은 適用 節次가 꽤 複雜하고 力學的으로 嚴密한 解를 産出시킬 수 도 있었다. 本論文의 結果로서는 任意의 格子桁橋에 對한 간단한 入力資料만으로 最大 Moment, Shear, Torsion, Deflection이 일어나는 格點들을 찾고 또 그 最大 Moment, Shear, Torsion, Deflection에 對한 影響線을 出力시키도록 하였고 또 각 部材에 對한 部材端力과 各 格點의 Deflection에 對한 影響線을 出力시키게 만들었다. The purpose of this paper is to introduce a new method of designing the grid girdered bridge using computer program. Leonhardt and Homberg's methods, which are presently used on designing of grid girdered bridge have various limitations in application. Futhermore these methods need complicated design procedures without giving exact solutions. The results of the study eliminates all these inconveniences and enables us to obtain the nodal points and influence line data of maximum moment, torsion and deflection only by preparing simple program input data for design of grid girdered bridge. The program also prints out the influence lines data for all member end forces and all nodal point deflections.

이희선,박헌우,임영득,이성규 西原大學校 基礎科學硏究所 1999 基礎科學硏究論叢 Vol.13 No.-

1997년 7월 24일에 중국측 백두산 달문지역의 고산초원을 대상으로 1 m × 1 m 방형구 40개를 설치하여 식물상을 분석한 결과는 17과, 35속, 29종, 3아종, 4변종으로 총 36종류가 확인되었다. 국화과가 7종으로 가장 많았고 다음으로는 벼과가 4종으로 많았다. 또한 협엽초본보다는 광엽초본이 많았으며, Salix metaformosa (눈산버들), Dryas octopetala var. asiatica (담자리꽃나무), Rhododendron aureum (노랑만병초), Vaccinium vitis-idaea (월귤) 등 키가 10∼15 cm의 왜소한 관목이 네 종 발견되었다. 방형구 내의 우점종에 따라 식생을 분석한 결과 17종류의 군락으로 분류되었으며, 이 중 Astragalus uliginosus (개황기)가 9개의 방형구에서 우점종으로 나타나 가장 많았고, 다음으로는 Sanguisorba sitchensis (큰오이풀)가 5개의 방형구, Deschampsia caespitosa (좀새풀)가 4개의 방형구에서 우점종으로 나타났다. The flora and vegetation of the alpine grassland at Dalmoon on Mt. Paektu were investigated on July 24, 1997 by 1 m × 1 m quadrat method. The flora of the vascular plants investigated on this alpine grassland was 36 taxa belonging to 17 families, 35 genera, 29 species, 3 subspecies, 4 varieties. The leading families were Compositae (7 taxa) and Gramineae (4 species), and the forb was more than the grass. Four dwarf shrubs which were Salix metaformosa, Dryas octopetala var. asiatica, Rhododendron aureum and Vaccinium vitis-idaea were found at the studied sites. This alpine grassland was composed of 17 communities, Astragalus uliginosus, Sanguisorba sitchensis, Deschampsia caespitosa were dominated over 18, 5 and 4 quadrats, respectively.

수치지형도를 활용한 홍수지도 제작용 지형자료의 효과적인 구축방법 연구

이근상,고덕구,김우구 한국지리정보학회 2004 한국지리정보학회지 Vol.7 No.1

한국수자원공사에서는 홍수지도 제작을 위한 정밀 지형자료 구축을 위해 LiDAR 측량을 실시하고 있으며, 향후 전국에 대한 홍수지도 제작시 막대한 비용이 소요될 것으로 예상된다. 따라서 홍수지도 제작이 꼭 필요한 지역을 선정하기 위한 사전모의용 자료구축을 위해 NGIS 수치지형도를 활용하는 것이 바람직하며, 이를 위해서는 각 축척별 수치지형도의 표고오차 분석이 필요하다. 본 연구에서는 수치지형도의 DEM 오차를 평가하기 위해 LiDAR 측량을 수행하여 구축한 DEM과 비교하였다. 특히 수치지형도로부터 구축한 TIN으로부터 DEM을 생성하기 위해 수행하는 보간법의 종류에 따라 발생하는 오차특성을 분석하였다. 분석결과 1:1,000 수치지형도가 1:5,000 수치지형도에 비해 오차가 작게 나타났으며, linear 보간을 수행한 DEM이 quintic 보간을 수행한 DEM에 비해 작은 오차특성을 보였다. 특히 도시지역의 경우 완만한 경사로 구성되어 있기 때문에 해상도에 따른 DEM 오차의 변화는 매우 작은 것으로 평가되었다. Korea Water Resources Corporation carried out LiDAR survey to construct detailed terrain data for flood mapping and it is expected that much money is required in flood mapping of all over the country. Therefore, it is desirable to use NIS digital map to construct preliminary modelling data for selection of flood mapping area. And the analysis of DEM error with respect to scale of digital map is necessary for the sake of applying digital map as the input data of flood mapping. We compared DEM from digital map with DEM from LiDAR survey. Especially we analyzed DEM error characteristics that is occurred with respect to the interpolation method that is used to construct DEM from TIN of digital map. As a result of analysis, digital map(1:1,000) showed smaller error than digital map(1:5,000) and DEM applying linear interpolation showed smaller error than DEM applying quintic interpolation. Especially, variation of DEM error by cell resolution was evaluated as very slight because urban district was composed of gentle slope.

이근상,박진혁,황의호,고덕구 한국지리정보학회 2004 한국지리정보학회지 Vol.7 No.3

임동 유역은 지질 및 토지피복 상태가 토사유실에 취약한 특성을 가지고 있어, 강우발생시 토사 유입으로 호소내 수질오염에 큰 영향을 주고 있으며, 특히 이러한 호소내 수질문제의 원인으로 저수지 사면의 토사유실 가능성이 제기되고 있다. 본 연구에서는 저수지 사면에서 발생하는 토사유실 기여율을 평가하기 위해, 최근 GIS 및 위성영상과의 연계가 가능한 RUSLE 모형을 선정하였으며 사면에서 발생하는 토사유실 정확도에 큰 영향을 주는 사면의 범위와 폭 그리고 사면상태를DB로 구축하기 위해 현지조사를 실시하였다. 임동유역에 대한 토사유실량과 비교하여 저수지 사면에서 발생하는 토사유실량과의 영향을 분석한 결과 약 2.64%로 나타났다. 따라서 이러한 결과를 볼 때, 임동 유역의 토사유실량에 비해 저수지 사면의 토사유실 영향은 상대적으로 낮은 것으로 평가되었다. Soil particles from rainfall flow into reservoir and give lots of influence in water quality because the geological conditions and landcover characteristics of Imdong watershed have a weakness against soil loss. Especially, reservoir slant is indicated by the main source area of soil loss. This study selected RUSLE model that could apply GIS and satellite image to evaluate the contribution rate of soil loss in reservoir slant. And we carried out an on-the-spot survey for the range, width and condition of reservoir slant that give much influences to the accuracy of soil loss. As the result of evaluation to the influence of soil loss in reservoir slant, it showed 2. 64% in comparison with Imdong watershed. In view of these results, the influence of soil loss in reservoir slant was evaluated in low comparing with Imdong watershed relatively.

이상희,김의한,오미혜,조현득,양승하 순천향대학교 교수학습개발센터 2004 Journal of Soonchunhyang Medical Science Vol.10 No.3

Gastric adenocarcinoma is the most common malignate tumor in Korea. Many oncogenes have been found in malignant tumor cells. Among these oncogenes, MT has high affinity for metals such as copper and zinc, The fuction of MT is metabolism and detoxification of copper and zinc, The relation between the expression of MT and prognosis of patients in various cancers are reported but is controversial. p53 is a regulator of cellular proliferation, and the over expression of p53 relates to malignant transformation and prognosis. To evaluate the expression of MT and p53 according to histopathologic fearures and the relation between these antigens and prognosis in gastric adenocarcinoma, we have performed immune staining, using mouse anti-MT and mouse anti-p53. The results were as follows; 1) The expression rates of MT and p53 in gastric adenocacinoma were 67.6% and 56.3%, respectively. 2) MT in gastric adenocarcinoma showed statisfically significant higher expression rate under 59 years than above 60 years(P=0.043). p53 showed higher expression rates under 59 yerars, but there is no significant difference(P-0.078). 3) MT showed statisfically significant higher positive rates in cases showing invasion within the gastiric wall than cases showing invasion surrounding tissue(P=0.051), but no significant difference according to progression, differentiation, lymph node metastasis or not. 4) p53 showed especially higher expression rates in advanced carcinoma than in early carcinoma(P=0.065), and no significant difference according to differentiation, invasing depth, lymph metastasis or not. 5) Gastric adenocarcinomas expressing MT(+) p53(-) are early carcinoma 14 cases(73.7%), advanced carcinoma 5cases(26.3%). There is statisfically significant difference compared to carcinomas showing MT(+) p53(+), MT(-) p53(-), MT(-) p53(+)(P=0.003). According to differrentiation, progression, lymph node metastasis or not there is no significant difference. 6) Correlation between MT and p53 in gastric adenocarcinoma were not seen. Above result indicated that MT in gastric adenocarcinoma may be related to progression of cancer. Also significant defference in early carcinoma showing MT(+) p53(-) may be indicates relation to prognosis.
