1984년 9 월부터 1985 년 8 월에 이르기까지 耽津江을 中心으로 한 上, 中, 下流를 對象으로 淡水 魚類分布를 把握하기 위하여 9個 地點을 調査를 實施하였다. 1) 本 調査에서 淡水魚 20科 75種 中 9科 12種은 淡水에서 採集 하였고 海産魚 3科 3種 도 採集하였다. 2) 現在까지 本 調査 地域에서 共通 優占種으로 나타난 種은 Plecoglossus altiveli, Carassius auratus이고 이 외에는 Cyprsnus carpio, Parasilurus asotus, Zacco platypus였다. 3) 本 調査에서 耽津江 淡水魚로 魚種은 23種으로서 다음과 같다. Coreo1eucisells sp1endidus, Moroco logowaskii, Moroco SP., Sarcocheilichthys czerskii, Gobiogobio, Gnathopogon striguts, Moroco semotilus, Microphysogobio koreensis, Microphysogobio lingictorsalis, Misgurnus mizolepis, Cobitis rolundicaudata, Cobitis taenia striate, Cobitis koreensis, Lefua costota, Pseudobagrus emarginatus, Liobagras andersonii, Pseudobagrus SP., Paralilurus microdorsalis, lateolabraxjaponica, Odontobwtis obscurus, Brachmystax lenok, trachydermus barhatus, Konosirus punctatus. 4) 우리나라의 特産 魚種 中 本 水系에서 棲息하고 있는 種數는 15種으로 상당히 많은 種이 棲息하고 있다. 5) 本 調査 地域에서 共通 優占種으로 나타나는 種은 다음과 같다. Plecoglossus altivelis, Carassius auratus이고 이외에도 Zacco platypus, Parasilurus asotus, Anguilla japonica였다. 6) 本 江에서 棲息이 確認된 稀貴 特産種 siniperca scherzeri, Lampetira japonica, Macropodus chinensis을 保護하기 위하여 保護 水域을 設定해야 한다고 생각된다. 7) 이 地方에 棲息하고 있는 Plecoglossus altivelis는 學術上으로 보아 특히 保護할 價値가 있다고 생각되며 보다 자세한 硏究의 必要性이 있다고 思料된다. 8) 本 調査 地域에서 種 異壤性과 均一性을 分析해 본 結果는 上流쪽으로 갈수록 安定度가 높고 種의 數와 多樣함을 보여 주고 있다. From September, 1984 to August, 1985. I selected nine places Centering around up, middle and down the Tam-Jin river, and then I came into force the search in order to have a grip on the aspects of the fishes in fresh water. I) In this search, I collected 9 families, 12 species among 20 families, 75 species of the fresh water fish in fresh water, and also collected 3 families, 3 species in the marine fish. 2) Up to date, the species that was found common dominance species in the places of this search are plecoglossus altivelis, carassius auratus and are additionally cyprinus carpio. parasilurus asotus and Zacco platypus. 3) In this search, the fish species that added to the fresh water fish in the Tam- Jin river are 23 species. They arc as follows: 4) Among the endemic fish species of our country, the number of species that lives in this water system are 15 species. Quite a few species live in this fresh water. 5) The species which was found common dominace species in the places of this search are as follows : They are plecaglossus altivelis, carassius auratus, and are additionally Zacco platypus, parasilurus asotus and Anguilla Japonica. 6) I ascertained that the rare endemic species live in this river, so I think that we must up the protective water area in order to protect them such as siniperca scherzeri, Lampetira Japonica and Macropodus Chinnesis. 7) From the scientific research point of view, the plecoglossus altivelis that lives in this place is particularly worth protecting. Also I think it is necessary to be made a study minately. 8) I analyzed the variety and the equality of species in the places of this search. As the result, I know to have a high stability as it goes along toward the upper stream and to show the variety in the number and the organization of species.

The action of phospholipid on the rhodotorucine A(Rh.A) acceptance by heterobasidiomyceteous yeast Rhodospori-dium toruloides mating type a cells and the effect of medium composition during sexual differentiation were investigated. Activation of trigger peptidase(TPase) was very sensitive to the originated phospholipid from R. toruloides and was more sensitive to phospholipid liposome made up of phospholipid. Phospholipid present on the membrane of mating type a cells consists of phospatidylglycerol(PG), phosphatidylethanolamine(PE), phospatidylcholine(PC), phospatidylinositol(PI), and phosphatidylserine(PS) of 12.9, suprisingly 45.4, 11.0, and 13.9%, respectively. As the result of using C-1 and N-1 mediums which limited C and N sources capable of inhibiting the synthesis of phospholipid. it resulted inhibiting sexual differentiation and production of Rh.A from mating type A cells.

표면 탄성파 디바이스의 전극재료로 사용되는 Al-1%Cu(4000Å)/tungsten nitride 박막을 magnetron sputtering법으로 제조하고 전기저항을 평가한 결과 비정질상의 tungsten nitride 박막을 제조할 수 있었고, 비정질 형성을 위해서 질소비 (R = N2/(Ar+N2))가 10∼40% 정도 필요하였다. Tungsten nitride 박막의 잔류응력은 비정질이 형성되면서 급격히 감소되었다. 이러한 비정질 박막위에 Al-1%Cu합금막이 형성되었다. 다층막은 453K에서 4시간 동안 열처리함으로써 3.6μΩ-cm의 저항를 나타냈는데, 이는 박막내 결정립 성장과 결정 결함의 감소에 기인하였다. As a power durable-electrode in SAW filter. Al-1%Cu/tungsten nitride multi-layer thin film was fabricated by magnetron sputtering process. Tungsten nitride films had the amorphours phase at the nitrogen ratio, R, ranging from 10~40%. The amorphization could be controlled by nitrogen ratio. R = N2/(N2+Ar) as a sputtering process parameter. Residual stress in tungsten nitride abruptly decreased with the formation of amorphous phase. Al-1%Cu thin film was deposited on the amorphous tungsten nitride. After the multi-layed thin film was annealed for 4 hours at 453K, the resistivity decreased as 3.6 μΩ-cm, which was due to grain growth and reduced crystal defects.

For the investigation of occurrence of insect pests and their natural enemies, total number of 353 controlled agricultural farms were visited and surveyed. In the 73% of total controlled agricultural farms, 52 species insect pests were occurred. Among these pests, the western flower thrip (Frankliniella occidentalis), the two spotted spider mite (Tetranychus urticae), the greenhouse whitefly (Trialeurodes vaporariorum), the cotton aphid (Aphis gossypii) and the green peach aphid (Myzus persicae) were mainly occurred. On the other hand, small numbers of natural enemies were sustained in 40 controlled agricultural farms, which was 11% and 17% of visited farms and pest occurred farms, respectively. For the most part of collected natural enemies, there were included in Braconid, Coccinellid and Anthocorid, as 63, 20 and 8% of them, respectively.

The CYP2D6 and N-acetyltransferase (NAT2) are polymorphic enzymes which are expressed in the hepatocyte in a genotype-determined manner. CYP2D6 and NAT2 are known to be involved in the inactivation and activation of various mutagens and carcinogens, respectively. The activities of the two enzyme systems are associated with the genetic susceptibility of many human cancers. This study was performed to determine the genotype frequencies of the two enzyme systems in primary hepatocellular carcinoma patients and healthy controls. One hundred healthy controls and 55 liver cancer patients were analyzed by polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP). The results are as followings:1. In the healthy controls, CYP2D6 wild type allele frequency was 0.985 and CYP2D6^*4 frequency was 0.015, and no CYP2D6 poor-metabolizer was detected. No significant differences were found in hepatocellular carcinoma patient group. 2. Frequencies of F, S1, S2 and S3 alleles of NAT2 system were 0.725, 0.01, 0.14 and 0.125 in controls, respectively. The genotype frequencies were found to be 0.91 of rapid acetylator and 0.09 of slow acetylator. No significant differences were found in hepatocellular carcinoma patient group. 3. These results suggest that the distribution of CYP2D6 and NAT2 polymorphisms is very unique in Korean populations characterized by extremely low frequency of CYP2D6 poor-metabolizer and NAT2 slow acetylator. CYP2D6 and NAT2 polymorphisms seemed not to play an important role in the hepatic carcinogenesis in Korean population.

Helicobacter pylori is a Gram-negative bacterium which causes chronic gastritis and is associated with gastric ulcer, duodenal ulcer and gastric carcinoma. In the process of screening of antibacterial activities against H. pylori from soil microorgani는, fungus No. 60686 was isolated. After fementaion of No. 60686, the antibacterial compound was isolated, purified and followed by extraction of mycelium with orgainic solvents, acetone and ethyl acetate, through silica gel chromatography, LH-20 gel chromatography and HPLC. As a result of the structural analyses of the compound by IR, ^1H- and ^13C-NMR, FAB/Mass spectrophotomer, the compound having the antimicrobial activity was idenfitied as chaetoglobosin A (C_32H_36N_2O_5), a cytochalasan derivative. The antimicrobial activity of chaetoglobosin A was tested against Gram-positive and negative bacteria by paper disk method. Among the test strains of 9 Gram-positive bacteria and 18 Gram-negative bacteria containing 4 H. pylori strains, the growth of 4 H. pylori strains and 3 S. aureus strains (SG 511, 285 and 503) was only inhibited by chaetoglobosin A. Also it was shown that its growth inhibition against H. pylori strains was stronger than that against S. aureus strains at the treatment of the same concentration. Therefore it was concluded that chaetoglobosin A has a specific growth inhibition against H. pylori of the tested bacteria.

Drowning is the second most common cause of accidental death of children in Korea. But the study of near-drowning is very rare in Korea. The purpose of our study is to determine the factors that may influence survival on the basis of submersion time, consciousness state upon admission to hospital, the kinds of water, laboratory findings and neurological outcomes. The survey was performed by a retrospective cohort study on 28 near-drowning victims of less than 15 years of age who were admitted to the emergency room in the Chosun University Hospital between May 1988 & May 1997. The results were as follows :1)Sex distribution was 22 males and 6 females. 2) Submersion time was <5 minutes in 9 cases, 5-9 minutes in 6 cases, 10-14 minutes in 5cases, 15-19 minutes in 3 cases, ≥20 minutes in 5cases. 3) Comatose patients upon arrival were 6/7 cases in the death group(86%) and 2/21 cases in the improved group(10%). They had unfavorable outcomes(P<0.05). 4) The first PH value was mean 7.02±0.12 in the death group and mean 7.31±0.13 in the improved group. There was a statistically significant difference between the death and the improved group(P<0.05) 5) The patients who gad increased blood glucose concentration were all 7 cases in the death group and 12/22 cases in the improved group(54%). The mean blood glucose concentration was mean 424.7235.6㎎/㎗ in the death group and mean 140.182.7㎎/㎗ in the improved group. There was a statistically significant difference between the death and the improved group(P<0.05). 6) The patients who had pulmonary edema upon arrival were all 7 cases in the death group and 1/21 cases in the improved group(46%). They had unfavorable outcomes(P<0.05). 7) The patients who had been submerged more than 15 minutes were all 7 cases in the death group and 6/21 cases in the improved group(5%). They had unfavorable outcomes(P<0.05). We conclude that pediatric victims of near-drowning can be assigned to high or low likelihoods of unfavorable our outcomes with the use of five variables ; comatose mentation upon arrival decreased initial blood pH, increased initial blood glucose concentration, pulmonary edema, and maximum submersion time estimated longer than fiften minutes. This prediction rule may be useful if it can be validated in another cohort.
