This experiment was conducted to investigate the effects of concentrated sulfate on the germination rate, growth rate and the productivity of weight of kudzu (Pueraria thwnbergiana Bentham). The germination rate of kudzu seed by one or two treatment retreatment with the concentrated sulfate for minutes of 5. 10, 15 and 20 were determined respectively. The results obtained were summarized as follows; 1. In the time of concentrated sulfate treatment, the germination rate was the highest in the once treatment for 20 minute. and the retreatment was higher than the once treatment in the germination rate. 2. The changes of plant length by growth stage was grown gradually until for 60 day and rapidly after for 60 day. The growth rate was the highest in treatment for 15 minute than in other treatments. 3. The stem diameter. stem weight. fresh weight and root weight by the treatment with sulfate 15 minute as the treatment with once were high degree of productivity. 4. The number of branch. number of nodes and root weight by the growth stage were higher growth rate before for 90 day than after for 90 day, however stem weight and fresh weight were high degree of productivity after for 60 day.

A matrix model of rice weevil population based on degree day (DD) was constructed. The basic matrix model predicted on exponential jncrcase of the adult weevil density and the finite rate of increase(h) of the population was estimated to be 2.155/100DD. Adult density simulated by the matrix model including intraspecific competition showed a damped oscillation over time and reached at the stationary level of 530 at 69, 300DD. The experimental population showed similar features to that of the model. But there were some differences in the highest density and period of adult oscillation. The differences could largely be caused by the assumption of the model; resource constancy.

The characteristics of de-emulsification of pertroleum emulsion by Nocardia amarae were investigated. Insoluble medium containing n-hexadecane was more effective than soluble medium in de-emulsification of emulsion containing diesel and bunker C as the organic phase. Emulsion made by the addition of xanthan or bioemulsifier was de-emulsified by N. amarae, and longer culture age was effective. In low viscosity range, organic phase with longer carbon chain was more effective. The contact, angle between bacterial film and water droplet in air increased from 16 degree for 4 day culture age to 26 degree for 15 day. The contact angle between bacterial film and water droplet in kerosene, n-heyxane or n-hexadecane also increased to greater than 100 degree after 3 day culture age. The hydrophobicity of bactgerial film increased according to the culture age.

Heterotopic abdominal homograft of canine heart was carried out in 20 pairs of dogs. Of these 12 cases were subjected as a control and 8 were subjected to immunosuppressive group. The dosage of immunosuppressive agent was 5mg/kg/day of Imuran [Azathioprine] for 3 days preoperatively, 10mg/kg on operative day and 5mg/kg/day postoperatively. For reducing the metabolic demand, the donor heart was preserved in 4degree heparinized saline solution for approximately I4 minutes. In the most of the cases, transplantation was performed with the technique of end-to-side aorto-aortic anastomosis and end-to-side pulmonary artery-inferior vena cava anastomosis at the infrarenal portion. Five out of 20 grafted dogs were survived more than one day. The longest survived 18 days in the control group and survive more than 60 days in the treated group. The survival cases were 3 out of 8[37. 5%] in the group of dogs treated with lmuran and 2`out of 12 [16.6%] in the group of non-treated. A prominent gross findings of the grafted heart was a minimal to moderate degree of dilatation of the heart with or without thrombosis in the cardiac chambers and/or anastomotic site. The case number 10, 15, and 19 showed moderate hypertrophy in grossly. The microscopic findings were as follows; 1. There were early hypersensitive histologic reactions such as interstitial edema, cellular infiltrations and early degenerative changes in the myocardium in the cases of 3 hour survival. 2. In the cases of more than 6 hours survival, organizing thrombosis of myocardial vessels, vasculitis,myocardial necrosis and lymphocyte, plasma cell, round cell infiltrations were noted. In the cases of more than 12 hours survival, the degree of these histologic changes especially in the non-treated group were more intensified than in the treated. 3. In the cases which survived more than one day, so called homograft specific histologic changes were milder in the immunosuppressive group compared with the control. 4. All the host hearts showed no evidence of pathologic findings histologically. Among the homologous canine cardiac transplantation tissue reaction, was milder and suvival time longer in the group treated with immunosuppressive drug.

The purpose of this study is to investigate the variable factors influencing children's interpersonal relationship skills and analyze the effects of marital perspective-taking ability, managing responses of young children and emotional intelligence on the interpersonal relationship skills of children. The study subjects were young children aged from four to seven attending private kindergartens or public day care centers in Seoul or Kyeongki-do and their mothers. The results are as follows : 1) First, marital perspective-taking abilities were indicated higher on boys than girls, children in a full-day program than those in a half-day program, university graduates or higher degree holders than collage graduates, single-income families than double-income families. In case of managing responses of young children, boys showed high avoidance of offensive disposition and girls showed high emotions dissipation. Also, young children in a full-day program showed non-responses on managing responses but high responses on emotions dissipation, and children of mothers with bachelor's degree or higher education showed support and children from double-income family showed no responses in high. Moreover, emotional intelligence of young children in a full-day program was higher than that of children in a half-day program, interpersonal relationship skills were showed higher on girls than boys, half-day children than full-day ones, children from single-income family than those from double-income family. 2) Meaningful relationships were indicated between these variables; managing responses of young children, emotional intelligence and interpersonal relationship skills by partly showing correlations. 3) Children in a half-day program with low in emotions dissipation, non-responses, offensive dispositional managing responses but high on Avoid, emotional intelligence showed high interpersonal relationship skills.

The phenological phenomena in terms of year day index (YDI) in South Korea were studied. The YDI was proposed here, because the remainer index such as Nuttonson's index is unadequate for the interpretation on the phenological phenomena of early spring season in sourthern coastal area. The YDI was calculated by summing daily mean temperature of the year days (YD) above physical zero degree in centigrade, based on the data of the Monthly Weather Reports from 1967 to 1980 by the Central Meteorological Office. The pattern of YDI increase with the increase of YD was similar to that of the remainder index such as the Nuttonson's index. The some YDI distribution maps were made by Yim and Kira (1975), dividing into 30'$\times$40' meshes, in latitude and longtude, on the topographical map(1 : 500,000) of the Korea Peninsula. According to the year day of different localities flowering dates of Prunus yedoensis and other phenological phenomena in various species delayed about 3.5 day as the increase of 1 degree of latitude, which coincides with the Hopkins bioclimatic law. It was found that the YDI is useful to interprete the phenology of plant and animal species and to select the optimum range of cultivars in South Korea.

Purpose : The purpose of this study is to compare the effect of Ulmus(root-bark) dressing with vaseline gauze dressing on burn wound(third degree) in rats. Method : Ten male Sprague-Dawley rats were used in the study. The rats were anesthetized with Ketamine l00mg/kg. burn wounds were made for each animal by specially designed apparatus. Ulmus dressing was applied once a day for 4 weeks in the experimental group(n=5), vaseline gauze dressing in the control group(n=5). The wounds were photographed and excised. Result : After 10 days of dressing, size of burn wounds of Ulmus dressing group decreased significantly compared to that of vaseline gauze dressing group. After 10 days of dressing, degree of inflammatory infiltration was shown lower in Ulmus dressing than in vaseline gauze group. There was no significant difference after dressing at day of 19 and 27 in degree of inflammatory infiltration.

The purposes of this study were to investigate the quality (structure and process) of home-based day care and center-based day care, and to examine socio-emotional development among infants who were in both types of day care. The subjects of this study were 101 infants who were in home-based day care and 181 infants who were in center-based day care. The measurements were socio-emotional development scale and assessment scales for day care programs. Results indicated that, first, home-based day care did not significantly differ from center-based day care in terms of structure. Second, home-based day care were, to some degree, significantly different from center-based day care in the process： home-based day care had better play environment and play activities than did center-band day care. Lastly, there were significant differences in socio-emotional development among infants according to the type of day care： infants in home-based day care were more independent to their teacher and felt more secure in child care homes than was true for the infants in center-based day care.

Purpose : This study aims to investigate the awareness of occupational therapists among managers and directors of adult day care centers in Korea to explore the cause of the low employment rate of these therapists and offer the results as basic data that can be used to expand occupational therapy at adult day care centers. Methods : This study collected data by conducting an online questionnaire with managers and directors of adult day care centers located in Seoul, Busan, Incheon, Daejeon, Gwangju, and Ulsan. A total of 70 completed questionnaires were divided into two groups a 'group with experience in occupational therapy information (OT experience)' and a 'group with no experience in occupational therapy information (OT inexperience)' and analyzed. Results : First, the 'OT experience' was found to have higher levels of awareness of the scope of work of occupational therapists than the 'OT inexperience'. Second, significant differences were found in the degree of awareness and necessity of occupational therapists and plans to employ occupational therapists later between the 'OT experience' and the 'OT inexperience'. Third, it was shown that there were significant correlations between whether the respondents were familiar with occupational therapy and the degree of awareness and necessity of occupational therapists and plans to employ occupational therapists later. Conclusion : Based on these findings, the following measures are recommended to expand the area of occupational therapy in adult day care centers, the need for occupational therapists should be mentioned in the health and welfare-related education for workers at these adult day care centers, policies such as a medical fee system for occupational therapy at these adult day care centers should be prepared.

This study investigated the effect of the addition of alcohol on the quality change of Chungkukjang during the aging, The Cung-kuk-jang was made by the degree of 3, 5, 10%, respectively, and determined NH2-N, NH3-N, total acidity, cell numbers, lactate, succinate and phenolic acid to measure the change of flavor component in the aging of 2$0^{\circ}C$. 1. In the treatment groups of different amount of alcohol and salt added and aging period of Chung-kuk-hang, NH2-N was more decreased with more addition of alcohol and salt in the 3-and 10-day of aging. NH3-N was increased gradually in the addition of up to 2.0% alcohol and then decreased in the 3-and 10-day of aging. 2. In the treatment groups of different amount of alcohol added and aging period Chung-kuk-hang, the total acidity was more decreased with more addition of alcohol and higher degree of salt. Cell number was decreased rapidly with the addition of 1.0% alcohol in the 3-day and then decreased relatively and in the 10-day of aging, and it was increased with the addition of alcohol 3. With the addition of alcohol and the different growing temperature, the content of phenolic acid was more browning changed at 3$0^{\circ}C$ than that of at 2$0^{\circ}C$ and the phenol content of each group was decreased with increasing the addition amount of alcohol. Thus, the more addition of alcohol amount would the more extend the period of Chung-kuk-hang aging.
