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.

在庫는 計劃期間동안 壽命을 갖는 在庫와 計劃期間內에서 劣化되는 在庫로 分類할 수 있는데, 本 硏究에서는 計劃期間內에서 時間의 흐름에 따라 劣化되는 경우를 다루었다. 그런데 지금까지의 在庫管理 方法에서는 在庫의 保管時 發生되는 品質劣化 損失費用을 保管費로 부터 分離시키지 않고 保管費의 一部로 포함시켜 取扱해왔다. 本 論文에서는 이와같은 不合理한 管理方法을 改善해 보기위하여 品質劣化損先費用을 獨立된 劣化損失費用으로 設定하여 生産準備費, 在庫保管費, 劣化損先費의 合을 最少化하는 經濟的 生産모델에 대하여 硏究하였다. We can classify such type of inventories into case, that is the one in which items becomes absolute at some fixed point in time, the other in which the product deteriorates throught the planning horizon. So, this paper is inventory model by the latter case, at presentation of optimal production period and economic lot size with degradation loss cost of independent. But, from what inventory control method until now, quality degradation loss cost have been handling part of storage cost that was not separated from storage cost to occurrencing during the storage of inventory. This paper separated quality degradation loss cost from the inventory storage cost and that research about the economic production quantity model which was able to minimized sum of production preparation cost, inventory storage cost, degradation loss cost.

The purpose of this study is to empirically examine the types of supplier relationships of Korean manufacturing companies. This analysis is divided into three steps, (1) finding major factors of supplier relationships, (2) clustering similar groups in supplier relationships, (3) examining the characteristics of the groups The result of the analysis is as follows First, by the factor analysis, four factors are found - information & technology assistance, finance assistance, payment, communication. Second, by the cluster analysis with four factors, three groups are generated Three groups consist of traditional supplier relationships, semi-supportive supplier relationships, supportive supplier relationships The difference of group of semi-supportive supplier relationships and supportive supplier relationships is the factor of finance assistance. Third, by the statistical analysis, it is verified that supportive group recognizes the risk of external environment more highly, and is more delivery performance oriented. And the correlation between groups and types of manufacturing systems were found.

In recently, much pesticides were used for control of agricultural and medical insects. The result of using pesticides were social problem because of environmental pollutions with pesticides in urban and farm village. The environmental pollutions were very serious. This experiment was conducted to eluciated of reduce to environmental pollution bring about using pesticides (organophosphates, carbamates, pyrethroids, and insect growth regulators) for control of medical insects(house fly, Musca domestica L and mosquito, culex pipiens pallens copuillett) and carried out the method of pest control. And the result are summarized as follows. The Kyongbuk house fly strain treated with pyriproxyfen on third instar larvae were very high mortality and low emergence. When use it, at the same time, we can reduce degree of environ-mental pollution and house fly populations. Using of imidan was effective in Seoul and Chungnam house fly strains. In mosquito larvae, the efficacy of icon to chungbuk strain, propoxur to Chungnam and Chungbuk strain, imidan to Kyongbuk strain, fenthion to Chungnam strain were excellent. In result of spraying imidan and icon on adult mosquitoes, the efficacy of icon was excellent than imidan. In esterase electrophoresis, third instar larvae of Chungnam house fly strain fed on artificial diet mixed with pyriproxyfen LC50 were very high activity of -Est-αl in early stage(second day after third instar larvae fed on diet), and the activity of Est-αl was very strong in late stage(se-vents day after third instar larvae fed on diet). In Kyongbuk strain, -Est-αl and Est-αl were detected in early and late stage, and activities of and -Est-αl and Est-αl were detected almost equally in late stage. It was very characteristic in this experiment. Third instar larvae fed on diet mixed with pyriproxyfen LC95 were detected -Est-αl and Est-αl almost equally. It was believed moulting control in insects. In electrophoresis with head, thorax, abdomen of house fly adult, -Est-α2 -Est-αl, Est-αl, Est-α2, Est-α3 were detected in abdomen in susceptible strain and only -Est-αl, was net detected in thorax -Est-αl, was detected in head, thorax and abdomen of Chungbuk strain and -Est-αl was detected in head, -Est-α2 in thorax of same strain. Activities of chitinase in late instar larvae of house flies fed on artificial diet mixed with pyrip-roxyfen LC50 and LC95, in pyriproxyfen LC95, analysised low and high again with the lapse of time in Kyongbuk strain. This was believed that the activity of chitinase was became high just before emergence. The result of filter paper test with mosquitoes were very high index(265) of esterase activity in Chungnam strain among all mosquito strains. In this reason, we can suppose that used pyrip-roxyfen (IGR) in Chungnam area for control pest. In this reason, it was more reasonable made use of pyriproxyfen than other pesticide in Chungnam area.

폴리설폰 중공사막에 대한 산소/질소 혼합물의 분리

국내 K-그룹 연구소에서 제조한 폴리설폰 중공사막의 산소/질소 혼합물에 대한 압력, stage cut, 공급기체 혼합물의 조성에 따른 분리성능을 조사하였다. 본 실험의 압력범위와 온도 30℃에서의 이상분리인자(O₂/N₂)는 5.7이었으며, 유입기체 혼합물의 21 mole% 산소농도가 약 50 mole%로 농축되었다. 저압츠과 고압측의 압력비는 산소농축에 미치는 영향이 적었으며, 이상분리인자의 영향은 매우 컸다. 그러나, 이상분리인자가 증가함에 따라 이상분리인자의 영향은 둔화되었다. 따라서, 이상분리인자가 큰 신소재 개발과 더불어 공정변수의 최저화가 필요하다. 수학적 모델링에 의한 예측치와 실험치가 잘 맞았다. The performance of the polysulfone hollow-fiber membrane manufactured by K-group Research Institute in Korea was investigated for the separation of O₂/N₂mixture as a function of pressure, stage cut, and feed gas composition. The ideal separation factor(O₂/N₂) at temperature 30℃ was around 5.7 in the pressure ranges studied. Oxygen concentration of 21 mole% in feed stream was concentrated to about 50%. Although the pressure ratio between high and low pressure side showed little effect, ideal separation factor showed greater effect on the oxygen enrichment. However, the effect was declined with increase in the ideal separation factor. Therefroe, the optimization of process variable is necessary as well as development of new material with high ideal separation factor. It was fond that experimental data were well correlated with the prediction of mathematical model.
