全南地方에 適合한 人蔘栽培法을 確立하기 위하여 1980年에 植付한 栽培地土壤의 化學性, 生育狀況, 栽培法, 人蔘의 成分 등을 調査 分析하고 1981年 全南地方에 適合한 栽植密度를 究明하기 위한 栽培實驗과 土壤別 化學性에 따른 人蔘의 生育狀況을 調査한 結果를 要約하면 다음과 같다. Ⅰ. 1980년 栽培地의 栽培環境, 生育狀況 度分調査 分析結果 全南의 氣象環境은 대체적으로 人蔘栽培가 可能하다고 생각되며, 土壤의 化學性은 pH가 높고 加里, 石灰, 苦土의 含量이 많은 傾向이나 燐酸, 有機物 含量은 適合한 편이다. 苗圃 象定地 選定官理는 比較的 標準栽培法을 따르고 있으나 고랑폭과 床高가 標準보다 낮은 것이 있다. 開匣과 播種은 一般的으로 標準에 따르고 있으며, 苗圃의 日覆構造는 前後柱의 높이가 標準에 比하여 높은 편이나 苗蔘栽培 官理나 生育狀態는 良好한 편이다. 本圃 豫定地 官理는 標準에 比하여 소홀한 경향으로 이 豫定地官理에 主意해야 될 것이다. 本圃 作판??에 있어서 通路와 床高가 標準에 比하여 낮은 傾向이고 日覆構造는 標準에 比하여 前後柱가 높고 前後柱差도 20∼30㎝가 높으며, 栽植密度는 72∼80本으로 標準보다 密植이며 缺株率이 매우 낮았다. 한편 人蔘의 成分은 一般的으로 2年根의 正象的 含量을 나타내고 있다. Ⅱ. 土壤 및 栽植密度別 生育調査 結果 供試土壤의 化學成은 pH는 6.0以上의 土壤으로 有機物 含량은 澤陽土壤이 높은 傾向이며 其他成分은 비슷하다. 土壤別 人蔘의 生育相黃은 土壤間에 거의 有意差가 없으며 ??陽土壤은 B土壤의 缺株率이 가장 높아 有意差가 있었으나 和順土壤에서는 C土壤의 缺株率이 가장 높으나 有意差는 없었으며 ??陽土壤이 和順土壤에 比하여 生育狀況이 良好했다. 栽植密度別 生育調査은 澤陽土壤은 處理間에 有意差가 거의 없으나 缺株率은 66主區가 가장 낮고 72株 以下에서 缺株率이 낮아지는 傾向이다. 和順土壤은 生育相과 缺株率이 處理間에 有意差가 거의 없으며 澤陽土壤에 比하여 生育이 不良하다. These studies were carried out to establish the cultural practice of ginseng(Panax ginseng C. A. Meyer) in Chonnam Area. The chemical properties of soil which were transplanted ginseng in 1980, growth status, cultivation method, and chemical composition of ginseng, were determined. Ginseng seedlings were planted with different soil and different plant density in 1981 and growth status was determined. The obtained results are summarized as follows. It is thought that the weather condition in Chonnam is able to cultivate ginseng cultivation, but that of phosphorus and organic matter was suitable for ginseng cultivation. Soil preperation for nursery bed was made in accordance with standard soil preperation in Korea. The stratification and sowing in Chonnam was carried out according to standard method. The hight of front and back pole of shade for nursery and permanant bed were higher than those of standard. The growth status of ginseng seedling in Chonnam Area was good. It is thought that the practice of soil preperation for permanent bed of ginseng in Chommam should be carried more carefully. The furrow of nursery and permanent bed was narrow, and height of ridge was low in comparison with standard. Plant density in Chonnam was more dense than thato of standard, and the rate of missing plant was very low. The chemical composition of 2 year-ginseng cultivated in Chonnam was searly same content in comparison with that in Chungbuk. The growth status of ginseng cultivated with different soil did not show significant difference in Tamyang or Hwasoon, but the rate of missing plant in B soil of Tamyang was significantly high, however that in Hwasoon did not show significant difference. The growth status of ginseng cultivated with plant density did not show significant difference in Tamyang or Hwasoon soil. The rate of missing plant in Tamyang was significantly low with low plant density, but that in Hwasoon did not show significant difference with plant density.

IIn order to investigate the fate of nitrogen in the submerged soil, Suchang, Hwasoon and Susan soil which have different properties, were treated with several fertilizers, such as ammonium sulfate, ammonium chloride, urea and SCU(mlfer coated urea), and incubated under water logged condition in 30 ℃ incubator. pH. NH₄-N₂?? NO₃-N and Fe?? in the soil and stagnent water, were determined at 5, 10, 15, 22, 30 and 60 days after incubation. The obtained results were summarized as follows. 1. pH of the stagnent water was 8~8. 5 in the urea plot and 6 ~ 6. 5 in the (NH₄)₂SO₄and NH₄C1 plot during the incubation. 2. PH content of the Suchang and Hwasoon soil was increased rapidly in the early stage of incubation, but that of Susan soil was increased gradually with the incubation period. It seemed that the change of Fe?? content depended on the organic matter of the soil. 3- NH₄-N content of stagnent water of all three sample soils was decreased gradually along the incubation period. 4- The amount of NH₄-Nin the soil on which NH₄Cl or(NH₄)₂SO₄was applied, was increased as the incubation periods while decreased in the urea plot. 5. NO??-N was determined in the stagnent water, and soil, but its content was changed irregularly during the incubation. 6. It seemed that NH₄-N in the stagnent water from the (NH₄)₂SO₄ or NH₄Cl could be absorbed gradually by the soil, but that from the hydrolysis of urea could not be absorbed by the soil. 7. In accodance with the above results, it was thought that nitrogen of NH₄C1 or (NH₄)₂SO₄ in the paddy soil was lost by the denitrification, but the nitrogen of urea was lost by both the denitrification and ammonia volatilization.

The purpose of this stud is to develop a differential diagnostic index between reactive and endogenous depressions with symptomatic variables obtained from Hamilton's rating scale for depressions. One hundred and forty one cases of reactive depression and 61 of endogenous depression examined in the outpatient clinics of Kyung Hee University Hospital and Hanyang University Hospital were included in this study. Each patient was checked on 17 symptom dimensions of Hamilton's rating scale for depression. Initially, 8 symptom variables significantly different between the two groups were extracted from the original 17 items by univariate analysis as follows: X₁: Depressed mood X₂: Guilty feeling X₃: Suicide X₄: Insomnia, initial X? : Work & interest X? : Retardation X? : Anxiety, psychic X? : Insight Discriminate function analysis was carried out on the above 8 symptom variables and discriminant function was turned out to be as follows. α=0.03X₁+0.405X₂+0.114X₃+0.07X₄+0.358X?+0.445X?+0.072X?+0.449X? In calculating the discriminant scores, discriminant coefficients in the above formula were multiplied by 100 for the convenience of computation. Distributions of the discriminant scores of 141 reactive and 61 endogenous depression patients were given in Table 3 and Figure 1. Mean discriminant score of reactive group was 504.96, while that of endogenous group was 745.25. Discrimination criterion was 620.1 of discriminant score. If discriminant score of a patient was below 620.1, he was assigned to reactive depression, and if it was above 620.1, he was assigned to endogenous depression. All the samples were rediagnosed by the above discrimination criterion and 110 of 141 reactive cases (78%) and 43 of 61 endogenous cases (70%) could be correctly classified to each original group. Thus, 153 of the 202 total cases (76%) were correctly classified, resulting in an overall error rate of 24%. These findings suggest that discriminant function analysis is a considerable useful statistical device in differential diagnosis between reactive and endogenous depressions and the eight symptom dimensions mentioned above are presumably available for discriminating the two groups of depression. Stepwise discriminant function analysis should be recommended in the future study for evaluating more significant symptom dimensions in the discrimination of reactive and endogenous depressions.

The aim of this study is to project the old people's sports lives and provide a fundamental data which is necessary in solving the aged problem through a study on the participation state of the old people's sports activities. The subject of this investigation is the aged, 681 persons (male 388, female 293). Who Jive in [C] City, [K] Provinced and more than sixty five years old. As the results of this investigation. the conclusions were as follows; 1. In the sports activities of the aged, the participation rate of the male was higher than nonattendance, the rate of the female was as equal as absence. The reasons of the participation were generally for maintenance or promotion, their health and personal relationship. 2. In the frequence of the sports activity, they have participated four or five times a week, more than eight percent. 3. They were active with their friends or individually. 4. They usually used the public sports establishments or public gardens. The satisfaciton rate was affirmative. 5. The aged showed affirmative emotion responses after the sports activities and these emotion responses appeared when they played cheerfully rather than the victory in the games. 6. Their favorite sports events were mostly jogging, gateball, mountain climbing, badminton and tennis. Their expecting events were similar. 7. The reasons why the aged don't take part in sports activities are the problems of their health and advanced age, the lack of the time and recognition about sports. They hope jogging, mountain climbing and gateball. 8. It developed that the improvement device for sports revitalization of the old is not only the enlargement of equipment and space to play with but the development and supply of programs for sports activities.

Gypsum products have potential contamination by infectious human pathogens, which could be transmitted from patient to the gypsum model via impression materials. Therefore disinfection and sterilization of gypsum products are recommended. Steam sterilization: namely autoclaving is widely available in dentistry. The aim of this study was to investigate degradation of mechanical properties for dental gypsum after steam sterilization. The effect of autoclaving on compressive strength, weight loss and dimensional accuracy of specimens of commercial die stone such as Crystal Rock(CR : Maruishi), Die Keen(DK : Columbus Dental), Resin Rock(RR : Whip Mix), Tuff Rock(TR : Talladium) were estimated, and experimental gypsums{(EP) : 0.5wt% accelerator, 0.02wt% retarder, 0.1wt% surface agent, 0.1wt% Poly Vinyl Acetate} were also measured the above properties after autoclaving. For each group, five cylindrical(6㎜ in diameter and 12㎜ long) specimens made with manufactures water:powder ratio. All specimens were dried in oven until reaching the constant mass. After dried, they were autoclaved at 121℃ for 20 minute, dried again. Compressive strength was measured before and after autoclaving using mechanical testing machine at a cross-head speed of 0.5㎜/min. The dimensional accuracy was estimated by length change of specimens with digital caliper before and after autoclaving. For statistical analysis, ANOVA Tukeys Studentized Range(HSD) test and T test were used. Compressive strength and weight were decreased in all samples after autoclaving. There is significant difference between CR, DK and RR, TR in after autoclaving(p<0.05). EP exhibited the highest compressive strength after autoclaving. The weight was significantly decreased in all group except RR after autoclaving(p<0.05). The dimensional accuracy was not significantly increased in all group except CR. As this result, we found that resin-containing dental stone is more appropriate for autoclaving in dentistry.

The purpose of this study is to understand the variation characters of the Protestant worship space after the Korean war which classified by evaluation of its period, type, denomination, and scale. The results are summarized as follows: (1) Postwar Korean Protestant worship space can be classified as 8 different shapes-rectangular, square, cross, trapezoid, circular, fan-type, elliptical, and irregular shape. (2) A rectangular type was traditional plan until 1968 before Je-Am church plan was introduced with a circular shape to furtherance diversification of the space plan. (3) The Presbyterian church dominated in adoption of a rectangular shape and the Methodist for a square type. This is an evident to make assumption that the Methodist is less conservative and open-minded to new forms. (4) Frequently as well, square, fan-type, and circular form is adopted in a small scale church. This phenomenon was not intended to shorten the distance between altar and nave, but rather related to exuviate from conventional form, pursuit symbolism, and imitation of an aptitude of a large scale church. (5) Application of the multi-media facilities and popularizations are the transformation factors of the worship ceremonies-provoke a conversion of a new church planning concept in the future.

The fact that with appropriate selection of the Ritz shapes, only a few of them can be used to represent adequately the response of the original system can be utilized very effectively in the forced response analysis of multi-degree-of-freedom systems. Obviously, a desirable set of Ritz vectors will be one that can adequately represent the spatial distribution of load by the superposition of a minimum number of shapes. It has been demonstrated that dynamic analysis based on Ritz vectors, which are generated by taking into account the spatial distribution of the load yield results which are more accurate than the use of the same number of exact mode shapes. However, because the dynamic response is influenced strongly by the exciting frequency, the exciting frequency in the use of Ritz analysis method is of considerable importance. In this paper, the influence of exciting frequency on Ritz analysis method is compared with mode superposition method with respect to displacement errors and base shear errors.
