Kim Choon Min, Chang Nam Kee and Chung Whan Ho: Decomposition rate of plant residue and the vertical distibution of mineral nutrients in the woodland soil. The relationship between decomposition rate of litter and the amount of mineral nutrients dispersed to the soil horizons were studied on the oak and pine forest stand. The results are as follows: 1. Decomposition rate of litter was highest in the F horizon of the oak stand, however in the pine stand it was highest in H horizon. 2. The correlation coefficients between decomposition rate and humus, organic carbon, moisture content, calcium, phosphorus, and nitrogen in the pine stand are; 0.90, 0.98, 0.76, 0.98, and 0.88, in oak stand; 0.97, 0.93, 0.92, 0.97, 0.74 and 0.73. 3. Factors which affect the decomposition rate of litter are humus, organic carbon, moisture content, calcium, phosphorus and nitrogen. 4. Among the variables, PH, moisture content and phosphorus under the oak and pine forest showed significant differences in each horizon. 5. C/N ratio of pine stands is higher than that of oak stands studied. 6. The vertical distribution of mineral nutrients is highly related with the amount of humus accumulated on top soil.

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.

본 연구는 정신분열병 환자들의 연성 신경학적 증상을 알아보고 또한 가족력 유무에 따른 연성 신경학적 증상의 차이를 살펴보기 위한 것이다. 1995년 7월부터 동년 10월까지 국립부곡정신병원에 입원치료중이며 DSM-IV 진단 기준에 의해 정신분열병으로 진단된 환자를 대상으로 하였다. 이중 병록지와 환자 가족의 정보를 근거로 하여 1차 인척 중에서 정신분열병의 기왕력이 있는 환자들을 가족력이 있는 환자군으로 분류하였다. Buchanan과 Heinrich의 신경학적 평가척도의 한국어판을 이용하여 가족력이있는 정신분열병 환자군20명, 가족력이 없는 정신분열병 환자군 20명 그리고 정상대조군 20명 사이의 연성 신경학적 이상소견을 비교하였다. 이 연구의 결과는 다음과 같다. 1) 연성 신경학적 평가척도의 총점은 정신분열병 환자군은 23.93±6.66, 정상대조군은 3.55±2.46으로 두 군간에 유의한 차이를 나타내었다(P<0.0001). 정신분열병 환자군은 감각통합 영역, 운동조정 영역, 복합활동순서화 영역, 그리고 기타 영역에서 정상대조군 보다 유의하게 높은 점수를 나타내었다(P<0.0001) 2) 연성 신경학적 이상 소견은 정신분열병 환자의 가족력의 유무와 유의한 상관관계는 없었다. 가족력이 있는 환자들이 신경학적 평가척도의 모든 영역에서 가족력이 없는 환자들보다 평균 점수가 높게 나타났으나 통계적으로 유의한 차이는 없었다. 이상의 결과에서 정상대조군보다 정신분열병 환자군에서 연성 신경학적 이상소견이 많이 나타났다. 이는 생물학적 표지로서의 연성 신경학적 증상의 중요성을 보여준다고 할 수 있다. 그러나 가족력 유무에 따른 연성 신경학적 이상 소견에 유의한 차이가 없었으므로 이 생물학적 표지가 trait marker인지 state marker인지는 좀더 연구를 해 보아야 할 것 같다. This study was performed to assess neurologic soft sign(NSS) in schizophrenics and to know the relationship between NSS and family history of schizophrenia. All Patients were hospitalized in Bugok National hospital during the period from July, 1995 to October, 1995 and diagnosed as schizophrenia based on DSM-IV criteria. Schizophrenics were classified as familial schizophrenics if at least one first-degree relative had a clear history of schizophrenia, based on review of any medical records and reports of family informants. The authors evaluated NSS using the structured tool for measuring neurological abnormalities, Neurological Evaluation Scale-Korean Version(NSE-K). A comparison of NSS score was made among three groups subjects consisting of 20 familial schizophrenics, 20 non-familial schizophrenics and 20 normal controls. The results were as follows : 1) the schizophrenics were significantly more impaired than normal controls on total scores of sensory integration, motor coordination, sequencing of complex motor acts and other areas(P<0.0001). 2) NSS scores were not correlated with family history of schizophrenia. Mean item scores of familial schizophrenics were higher than non-familial schizophrenics but there were statistically no differences between two groups. these findings suggest that abnormal NSS may be one of possible biological markers of schizophrenics. But there were statistically no differences in NSS scores between familial schizophrenics and non-familial schizophrenics. therefore, A further study is needed to investigate whether NSS is a trait marker of schizophrenics.

The Mechanical Alloying(MA) process with high mechanical properties of dispersion strengthened MA Al-Ti-B alloys were invested in order to evaluate their Stress Corrosion Cracking(SCC) applications. The experimental apparatus of SCC test was slow strain rate test facility. Al-Ti-B alloys had better SCC susceptibility in pH=2.01 or pH=13.2 solution than pH=6.81 solution. In this study Al-Ti-B alloys by MA had more SCC resistance than Al-Ti alloys Al 7075-T73 alloys. But, in addition of B to Al-Ti alloys had the characteristics of brittle, in binary Al-Ti alloys was ductile.

조석류 해석의 제1보로서, 유한요소법으로 천해역에서 조석방정식을 해석해 보았다. 본 계산의 결과는 실제의 결과와 일치하는 것을 알 수 있으므로, 해석방법의 타당성이 인정된다. 따라서, 복잡한 형태로 되어 있는 지형을 대상으로 하는 경우, 본 해석방법이 종래의 유한차분법보다 실용적이라 할 수 있겠다. 개발된 유한요소법의 수치모델을 현지에 적용할 경우는, 본 계산에서는 생략되었지만, 2차원적으로 작용하는 외력항을 고려할 필요가 있는 것으로 사료된다. In this paper, a numerical model of the tidal current problem by using finite element method is described. Assuming that the tidal current is periodic motion, the Galerkin approach with linear triangular elements is employed as the numerical integration procedure in space. Also, shallow water theory neglecting the bottom friction, wind force and Coriolis force is employed. In order to stabilize the computing procedure, two-step explicit method, so-called the Kawahara scheme, is applied for the discretization of time. By the computation of numerical examples, it is shown that the present finite element method is suitable, and good results are attained.

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.
