게르마늄의 약리효능이 알려짐에 따라 게르마늄이 깅화된 기능성 농산물의 요구도가 높아지는 추세이다. 본 연구는 게르마늄의 농업적 이용에 대한 기초 사료를 제공하고자 실시하였으며, 벼의 생육 및 게르마늄 흡수에 미치는 게르마늄처리 효과는 다음과 같다. 게르마늄을 0, 2.5, 5.0, 7.5 및 10.0 mg/kg으로 처리할 토양을 와그너포트에 넣어 벼를 재배힌 결과, 게르마늄 처리농도가 증가할수록 게르마늄 독성의 증가로 초장, 수장, 수수 및 수량이 급격히 감소하였으며 게르마늄 2.5 mg/kg 이상에서는 게르마늄 독성이 발생하였다. 게르마늄 처리농도가 증가할수록 벼의 게르마늄 흡수랑은 증가하였으나 벼의 게르마늄 이용율은 게르마늄 2.5, 5.0, 7.5 mg/kg 처리에서 각각 20.7, 12.5 및 7.5%로서 게르마늄 처리농도가 증가할수록 감소하였다. 벼의 부위별 게르마늄 함량은 볏짚>왕겨>현미 순으로 높았다. 게르마늄 2.5 mg/kg 처리시 볏짚, 왕겨 및 현미의 게르마늄 함량은 각각 103.4, 30.2 및 3.02 mg/kg 이었고, 볏짚과 왕겨에서는 게르마늄 무처리에서도 각각 2.9 및 3.9 mg/kg을 함유하고 있었다. 쌀의 아미노산 함량을 분석한 결과 게르마늄 처리농도가 증가할수록 Asx., Thr., Ser. 등 대부분 종류의 아미노산 함량이 증가하였으며, 그 결과 현미중 질소흡수량도 증가하였다. In order to obtain the basic information for agricultural utilization of Germanium(Ge), the growth characteristics and Ge absorption of rice plant were investigated with different Ge concentration in soil. Ge concentrations were treated with 0, 2.5, 5.0 7.5 and 10.0 mg/kg in pot(1/5,000a), respectively. As higher the Ge concentration in soil, the Ge absorption amount in straw, husk and brown rice were increased. But the yields were decreased with the increase of Ge phytotoxicity. When rice plant was grown more than 2.5 mg/kg Ge(as GeO₂) in the soil, growth was inhibited by germanium phytotoxicity and necrosis spots were observed in the rice leaf blades. Therefore the optimum concentration of Ge was less than 2.5 mg/kg in rice plant. When rice plant was cultivated on soil supplemented with 2.5 mg/kg Ge, Ge content in straw, husk and brown rice was 103.4, 30.2 and 3.02 mg/kg, respectively. The Ge content in plant was high in the order of straw > husk > brown rice. Most of the amino acids in rice were increased with the increase of Ge treatment, besides, total amino acid contents also increased.

The purpose of the study is to analysis runoff of urabn watersheds by the urban runoff model which can perform the channel flood routing, The urban runoff model used BRRL model and ILLUDAS model. The urabn watersheds selected Geuck-nak Chun Drainage Basin and Sang-Mu Drainage Basin. The two basin is located in Seo-Gu, Kwangju. To apply this model the basin is devided into contributing areas or subbasins. With this information, the time-area for contributing is derived. The rainfall pattern analysis on time distribution characteristics of rainfall rates is important in determination of design flow for hydrologic structures, particularly in urban area drainage network system design. The design rainfall assessed from the empirical formula of rainfall intensity and the temporal distributions of that rainfall determined on the basis of Huff’s method from the historical rainfall data of the basin. The urban runoff model tested in this study can be applied to compute the runoff in the urban stream channel as well as from the small urban drainage area.

Objectives : The purpose of this study was to examine the sociodemographic characteristics and the comorbid psychiatric disorders and the effect of methamphetamine use on psychiatric symptoms in methamphetamine abuse or dependent patients. Methods : The study subjects were 44 hospitalized male patients who met the DSM-Ⅳ criteria for methamphetamine abuse or dependence. The study included items assessing the sociodemographic profiles, history of substance use, and psychiatric symptomatology. Psychiatric assessments were based on SCL-90-R, BPRS, HRSD, YMRS and Impulsive scale. Results : In methamphetamine use patients, 93.2% were depressed and 59% had moderate to severe depression There were significant differences in interpersonal- sensitivity, hostility and phobia in the 3rd decade age group, interpersonal-sensitivity and impulsive scale in .under the middle school education group, and obsession-compulsion, anxiety, hostility and. YMRS in no-job group, respectively compared to the other groups. Age of the first use was correlated with the frequency of use, and also with the duration of illness, but not with the number of incarceration. There were positive correlations among HRSD, BPRS and impulsive scale. In the above 500 times used group there were significant differences in anxiety, hostility, phobia and paranoia compared to the below 100 times used group. Conclusion : In methamphetamine abuse or dependent patients, the incidence rate of comorbid depression was 93.2%. In the 3rd decade age group, under the middle school education group and no-job group showed higher diverse psychiatric symptoms compared to the other groups. Frequency of use was positively correlated with the symptoms such as anxiety, hostility, phobia and paranoia. We suggest that relevant psychiatric evaluations are needed for all methamphetamine users.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.

Helicobacter pylori infection was the cause of chronic gastritis, duodenal ulcer and gastric MALT lymphoma. The eradication rates of H. pylori using antibiotics are around 80%. Lactobacilli have been demonstrated to have in vivo and in vitro inhibitory effects on H. pylori infection. We aimed to evaluate the inhibitory effect of L. lactis CBT-8 and its extract on H. pylori in human stomach. Thirty-five H. pylori-infected volunteers(30-49 yr)were randomized into two groups which were treated with L. lactis CBT-8 and its extract(Group A n=17) or milk containing L. lactis CBT-8(Group B, n=18). They underwent 13C-urea breath tests before and after treatment. The DOB30 of group A(n=14) was decreased 41.0% after treatment(26.0±4.9 before, 15.3±2.1 after treatment)(p<0.05). the DOB30 of group B(n=13) was decreased 22.3% after treatment(22.0±2.2 before, 17.1±1.7 after treatment)(p<0.05). In conclusion, L. lactis CBT-8 was effective in suppressing H. pylori infection in human stomach.

The College of Engineering was specialized to have a sole function for supplying technical high school teachers in 1977 and referred to as the College of Industrial Education according to the Government's policy. The economic impact mainly due to the oil-crises caused a severe problem to this college, namely discrepancy of supply to demand scale. Accordingly the number of student enrollment was to be fluctuated from 479 in 1979 through 800 in 1979 and 900 in 1980 to 430 in 1981. And the engineering departments have been attached to this Engineering Education College since 1981. These circumstanses met singnificant inefficiency in facility operation. This program aims at providing an overall relocation of the college facilities and preparing the practical system to make the joint-operation possible taking into account circulation, academic stream, budget, maintenance, etc. However this study could not get optimal spacing but some trade-off, considering the current situation.

Neuronal migration disorders(NMD's) are a rare group of development structural lesions characterized by disorganization of cortical architecture with aberrant columnar and laminar neuronal arrangement, often causing intractable seizures. During September 1994 to February 1995, we operated on six patients with NMD to treat intractable seizures. Male to female ratio of these 6 patients was 2 : 4, and mean age at seizure onset was 14 years old(range 6-28 years), indicating early onset of epilepsy. Mean age at seizure surgery was 29 years old(range 23-41 years), and mean follow-up duration after operation was 4 months(range 3-6 months). In their past medical history, three patients had experienced febrile seizure at pediatric age, and one of them had a history of anoxic damage during delivery. Following preoperative localization, the lesion was removed completely in five patients. In the other one patient, part of the lesion was located in the speech and motor area, leading to partial removal. On histologic examination two of them showed cortical dysplasia and the other four revealed microdysgenesis. During follow-up for six months, five patients were free of seizure and in the other one patient, whose lesion was removed incompletely, the frequency of seizure decreased by 95%.
