Community mental health management system emphasizing on the rehabilitation and the return to the community has been established and carried out for many years. The study has been demanded to prove that the decreasing rate of the recurrence of the mentally ill resulted to lower their medical costs, to enrich the quality of life, and to reduce the psychological burden of their family. This study tried to prove that the mental health services to the mentally ill which were registered in community mental health center of A city have an influence on the medical cost, the quality of their lives. the family burden. The subject group of this study were 39 home-based mentally ill patients and their 37 family members, totally 76 people registered in mental health center of A city and participated in its program. This research had been measured twice, the first before the intervention and the second after at least a year. The measuring tools in the research were the medical cost measurment tools developed by the researcher, the quality of life index by Yoo ja, Noh(1988) and the family burden by Montgonery(1985). The methods were modified and supplemented in this study. This research made use of SPSS Win 10.0. The results of this study are the same as followings. 1) There were the significant difference in the medical cost before and after the mental health service delivery. 2) The quality of lives of the mentally ill, after the mental health services delivered were significantly higher than before. 3) The family burden were significantly reduced after the delivery of community mental health services. Community mental health services brought out efficient results to the social return and rehabilitation. And these results means that the mentally ill changed highly the quality of life and their burden of family and medical cost were reduced. So the public organization and the private society should help positively the mentally ill and their family through mental health policy and social service agency to live healthy lives and to be valuable member of society.

This study examined the effects of growth retardants and midsummer drainage on lodging-related characters in direct seeding rice culture on flooded paddy surfaces. Treatments included in this study were continuous flooding, two time midsummer drainages (TTD), and inabenfide or trinexapac-ethyl application after TTD. Culm length was reduced most by 11.4cm in trinexapac-ethyl treatment after TTD, followed by 4.1cm in inabenfide treatment after TTD compared to TTD treatment. A significant reduction in culm length occurred at the 3rd internode in inabenfide treatment applied at 40 days before heading (DBH), while trinexapac-ethyl application at 8 DBH reduced the 3rd>2nd>1st internode. The culm diameter of the 4th internode was increased by the application of trinexapac-ethyl following TTD compared to TTD treatment. Thickness of culm wall was significantly increased by trinexapac-ethyl but not by inabenfide applications. Lodging index was the highest in continuous flooding and the lowest in trinexapac-ethyl treatment after TTD. Subsequently, field lodging did not occur in plots treated by trinexapac-ethyl. Rice plants subjected to midsummer drainage or growth retardants showed higher ripened grain ratio and 1000-grain weight, resulting in higher rice yield. These results indicate that trinexapac-ethyl, which can be applied at the relatively later growth stage after proper judgement of lodging occurrence, could be a useful tool for reducing lodging in direct seeding rice culture on flooded paddy fields.

Viviparous germination causes yield loss and quality deterioration of rice. This study was conducted to investigate varietal differences of the viviparous germination with different days after heading (DAH) and different temperatures. In the laboratory examination, the averaged germination rate of all varieties at 45DAH and at 25DAH was 79.9%, and 27.5% under the incubation at the temperature of 3$0^{\circ}C$/2$0^{\circ}C$ (day/night) for 12 days. Andabyeo, Da- sanbyeo, and Nonganbyeo showed the lowest viviparous germination rates among the tested varieties. The shoot length of the viviparous germination measured 12days after incubation at 30/2$0^{\circ}C$ ranged from 21 to 53mm, indicating significant deterioration of rice quality. In the field test, the averaged viviparous germination rates of rice varieties at 25, 35, 45DAH with the underwater conditions for 4 days were 2.2, 6.2 and 9.2%, respectively, while their rates at 12 day after underwater conditions increased to 17.6, 44.2 and 43.8%, respectively. A variety that showed the highest viviparous germination rate at 25 and 35 and 45DAH was Heukjinjubyeo. When standing rice panicles without lodging were examined after consecutive raining for 7 days Juanbyeo showed the highest viviparous germination (45.5%), followed by Odaebyeo (16.0%), Jinbubyeo (14.5 %), Bongkwangbyeo (14.2 %) and Obongbyeo (12.6%). The viviparous germination of rice was greatly affected by variety, days after heading and temperature settings. Bongkwangbyeo, Juanbyeo, Dongjinbyeo, Hwasunchalbyeo, Naepoongbyeo and Heukjinjubyeo were classified as the most susceptible varieties to the viviparous germination in the field conditions.

Background: This study was carried out to determine the best time for collecting ginseng berries without reducing the ginsenoside-Re content of ginseng roots, which are used as food, medicine, or cosmetic materials. Methods and Results: The test variety of ginseng used in this study was is Chunpung, which was collected from a 4-year-old ginseng field. Ginseng berries were collected at 7, 14, 21, 28, 35, 42, 49, and 56 days after flowering. The number of berry bunches per $1.62m^2$ ranged from 43.4 to 61.4, while the weight of berries per $1.62m^2$ was the greatest when they were collected 49 days after flowering. The root fresh weight per $1.62m^2$ was increased by 0.21 - 1.00 kg compared with that before the test, but root weight gain was decreased as the berry collection time was delayed. Total ginsenoside content of 4-year-old ginseng was the highest when berries were collected 7 days after flowering, while the ginsenoside-Re contents was the highest when collection was done 14 days after flowering. Conclusions: The most suitable period for ginseng berry collection was proposed to be from 14 to 21 days after flowering, as this is when the content of ginsenoside-Re, which is useful as a medicinal or cosmetic material, is still high and the ginseng root has not yet decreased in weight.

Web-based services have fundamentally confidential problems due to characteristics of internet environment such as anonymity. These problems are serious obstacles to grow the web-based services. The security and confidence of web-based services rely on both service provider and users' opinion. But the former has difficulty in trusting the service provider and the latter takes too long time to propagete all users after converging their opinion. Therefore it is necessary to establish the objective and confidential evaluation and certification program for web-based service. In this paper, the internal and external web-based services evaluation and certification programs are compared and analyzed. The critical factors and evaluation methodology for secure and confidential web-based service are identified. Finally, this paper provides the improvement and strategy for web-based services evaluation and certification program.

This study was conducted to find qualitative approaches to occupational reference to group health practices. In-depth interviewing was done on 8 subjects health monitor members, owners and occupational nurses, respectively). The major findings were as follows; 1. Visiting health management Useful services were 'health counseling', 'medical examination', 'providing informations about managing diseases', 'agency business in relation to Labour Ministry' and 'giving a recognition about occupational health service to owners'. Insufficiencies were 'lack of treatment service after medical examination' and 'lack of follow up services constantly'. 2. Occupational nursing service Useful services were 'providing health information' and 'counselling about health'. Major contents of occupational nursing services were 'management of occupational and adult diseases' and 'explanation of the results after medical examination'. Insufficiencies were 'deficiency of the place where group health education could be performed', 'lack of additional or closer examinations needed in counselling' and 'discontinuous selection of additional or more exact examinations'. 3. Health monitor members Health monitor members in industries were classified into two. Some were selected by owners and the others were selected simply by considering their administrative abilities such as proficient management of documents. Their major tasks were to connect workers with occupational health management agencies. This study suggests that programs should be developed which enable health monitor members to cooperate with occupational nurses.

Pleurotus eryngii is one of the most commercially important mushrooms cultivated in Korea. However, the shelf-life of the fruiting body is short, limiting its export. A new hybrid strain H17 of P. eryngii was developed to extend the shelf-life by mono-mono crossing between monokaryotic strains derived from DanBi and KNR2774. Although the cultivation period of H17 was slightly longer than that of the reference cultivar Kenneutari No.2, the quality did not change and remained normal after a period of 65.0 days at $4^{\circ}C$. This result was significantly different from that of the reference cultivar Kenneutari No.2. Analysis of the genetic characteristics of the new hybrid strain H17 revealed a different profile from that of the parental and reference cultivars when random amplification of polymorphic DNA (RAPD) primers was used. These results demonstrate that H17 is a new cultivar with improved storability after harvesting.

This study was carried out to determine the effects on rice growth, yields and soil improvement under the different nitrogen levels in machine-transplanted rice after plowing at the fruiting stage of milk vetch. The fresh weight of milk vetch at plowing time was 20.95 ton/ha. In dry weight, T-N and C/N were 1.58%, 21.8%, respectively. Organic matter, total nitrogen and exchangeable calcium of soil after the experiment in the plot of milk vetch were higher than those before the experiment. Leaf area and dry weight of rice plants at heading date increased as nitrogen level increased. The number of panicle and spikelets per $\textrm{m}^2$were not different except for the 110 kg/ha nitrogen level plot with milk vetch. Brown rice yield ranged from 5.45 to 6.08 ton/ha, in creasing with increased nitrogen level. So the yield increased by 1% at 77 kg/ha nitrogen level, 7% at 110 kg/ha nitrogen level plot with milk vetch compared with conventional level (rice straw 5.4 ton/ha and nitrogen 110 kg/ha).
