The purpose of this study is to establish the databases of pollutant sources and water quality measurement data by utilizing GIS, and making the user interface for the management of pollutant sources. Yeongsan Estuarine Lake was formed of a huge levee of 4.35 km constructed by an agricultural reclamation project. Water quality of the reservoir has been degraded gradually, which mainly attributes to increase of point and non-point source pollutant loads from the lake's watershed of 33,374.3 $\textrm{km}^2$ into it. Application of GIS to establishment of the database was researched of pint source such as domestic sewage, industrial wastewater, farm wastes, and fishery wastes, and non-pont source such as residence, rice and upland field, and forest runoffs of the watershed of the lake. NT Acr/Info and ArcView were mainly utilized for the database formation. Land use of the watershed using LANDSAT image data was analyzed for non-point source pollutant load estimation. Pollutant loads from the watershed into the reservoir were calculated using the GIS database and BOD, TN, TP load units of point and non-point sources. Total BOD, TN, TP loads into it reached approximately to 141, 715, 2,094 and 4,743 kg/day respectively. The loads can be used as input parameters for water quality predicting model of it. A user-friendly interface program was developed using Dialog Designer and Avenue Script of AcrView, which can perform spatial analysis of point and non-point sources, calculate pollutant inputs from the sources, update attribute data of them, delete and add point sources, identify locations and volumes of water treatment facilities, and examine water quality data of water sampling points.

In order to provide basic references for the design of heating on simple silkworm rearing house, the actual change of heating load coefficient by progress of adult silkworm rearing day from the reared in silkworm rearing house, the heating load coefficient by types of silkworm rearing houses and the heating requirement and the maximum heating load by types of silkworm rearing houses were determined. The results obtained from the study were as follows : 1. The average heating load coefficients of NS, OS and CC type simple silkworm rearing houses were $24.1KJ/m^2-hr-^{\circ}C$, $19.8KJ/m^2-hr-^{\circ}C$, and $10.8KJ/m^2-hr-^{\circ}C$, respectively. 2. The change of heating load coefficient by progress of silkworm rearing day after reared into simple silkworm rearing house could be expressed as Fig. 4. 3. Heating degree-hour for adult silkworm rearing in Suweon district was calculated as $951.6^{\circ}C-hr$ for spring season and $610.5^{\circ}C-hr$ for autumn season. 4. Yearly heating requirement of the NS type was estimated twice more than that of the CC type. Thus, some kinds of reinforced thermal adiabatic facilities is desirable for NS type. 5. The time for maximum heating load was turned out at the 4th instar during the spring season and after the mounting during the autumn season. 6. This study was performed in Suweon district. However, the estimated and analyzed data could be adapted to the major silkworm rearing district if their meteorology data were adjusted.

The purpose of this study was to investigate the effects of group combined intervention that combined animal-assisted therapy and integrated elderly play therapy on the depression, self-esteem, and emotional expression of geriatric patients residing in nursing homes. This was achieved by providing cognitive, physical, and emotional activities and social interaction at the same time. The group combined intervention method was applied to twelve elderly patients (six in the control group, six in the experimental group) aged 65 or older who live in a nursing home for the elderly in C province, from May 3, 2019 to June 21, 2019, for a total of 8 times (once a week, 50 minutes at a time). The quantitative evaluation was analyzed through SPSS 21.0 for comparison before and after the program was implemented, using the Korean version of the depression and the self-esteem scale. The qualitative evaluation compared emotional expression pre-test and post-test. The major results of the study were as follows: First, the group combined intervention was effective in reducing depression levels of the experimental group among the elderly patients. Second, it was effective in improving the self-esteem of the experimental group among the elderly patients. Third, it showed a significant difference in the emotional expression of the experimental group among the elderly patients. Therefore, it was found that group combined intervention reduces depression and improves self-esteem and emotional expression of the elderly. Based on these results, it is hoped that this study will be a cornerstone in the development of concrete programs for the benefit of elderly patients living in facilities.

Background: The present study aimed to analyze the index value trends of injured employed persons (IEPs) covered in Pakistan Labour Force Surveys from 2001-02 to 2012-13. Methods: The index value method based on reference years and reference groups was used to analyze the IEP trends in terms of different criteria such as gender, area, employment status, industry types, occupational groups, types of injury, injured body parts, and treatment received. The Pearson correlation coefficient analysis was also performed to investigate the inter-relationship of different occupational variables. Results: The values of IEP increased at the end of the studied year in industry divisions such as agriculture, forestry, hunting, and fishing, followed by in manufacturing and construction industry divisions. People associated with major occupations (such as skilled agricultural and fishery workers) and elementary (unskilled) occupations were found to be at an increasing risk of occupational injuries/diseases with an increasing IEP trend. Types of occupational injuries such as sprain or strain, superficial injury, and dislocation increased during the studied years. Major injured parts of body such as upper limb and lower limb found with increasing trend. Types of treatment received, including hospitalization and no treatment, were found to decrease. Increased IEP can be justified due to inadequate health care facilities, especially in rural areas by increased IEP in terms of gender, areas, received treatment, occupational groups and employment status as results found after Pearson correlation coefficient analysis. Conclusion: The increasing trend in the IEP% of the total employed persons due to agrarian activities shows that there is a need to improve health care setups in rural areas of Pakistan.

본 연구에서는 시계열 항공영상을 이용하여 갑천의 토지이용 패턴을 제내지와 제외지로 구분하여 분석하였다. 먼저 제내지에서는 주거지, 도로, 공업지, 공공시설이 도시화 증가항목으로 선정된 반면, 농경지, 산림 그리고 하천은 도시화 감소항목으로 분류되었다. 또한 이러한 증가와 감소항목들이 1988년도를 기점으로 역전되는 경향을 나타내었으며 이를 통해 갑천의 토지이용이 1988년을 기점으로 도시화로 전환되었음을 추정 할 수 있다. 제외지에서는 시간이 경과함에 따라 현하천의 면적이 감소하는 것으로 나타났으며 이는 고수부지, 교량 그리고 보와 같은 도시화를 반영하는 토지이용 항목의 면적이 증가된 것을 의미한다. 또한 수문자료를 고려한 현하천에 대한 수계의 비율은 시간이 경과함에 따라 증가하였다. 전반적으로 볼 때, 항공영상은 하천관리 및 계획에 필요한 토지이용 정보를 구축하는데 유용하게 활용될 수 있으리라 판단된다.

Recent researches on plant factory system deal with the convergence of lighting technology, agricultural technology inclusive to the high-tech industries worldwide in order to respond to the decreasing crop harvest due to global warming and abnormal weather phenomena. However, the fundamental performance standard is not currently being introduced in the case of plants factory and its commercialization is not activated because of high initial investment and operating cost. Large portion of the initial investment and operating cost of a plant factory is ascribed to artificial light sources and thermal control facilities, therefore, innovation should be provided in order to improve the economics of the plant factory. As an alternative, new plant factory could harness solar thermal and geothermal systems for heating, cooling and ventilation. In this study, a natural light dependent multi-layer plant factory's thermal environment was analyzed with two-dimensional numerical methods to elicit efficient operation conditions for optimized internal physical environment. Depending on the supply air temperature and airflow rate introduced in the facility, the temperature changes around the crops was interpreted. Since the air supplied into the plant factory does not stay long enough, the ambient temperature predicted around the plating trays was not significantly different from that of the supplied air. However, the changes of airflow rate and air flow pattern could cause difference to the temperature around the planting trays. Increasing the amount of time of air staying around the planting trays could improve energy performance in case the thermal environment of a natural light based multi-layer plant factory is considered.

Livestock is considered central component in agricultural sector of Pakistan, provides employment to more than 8 million families. Meat and meat products holds pivotal significance in meeting dietary requirements serving as major protein source and provide essential vitamins and minerals. Globally, consumer demand is increasing for healthy, hygienic and safe meat and meat products due to growing population, income level and food choices. As, food choices are mainly influenced by region, religion and economic level. However, religion is one of the major factor to influence the food choices. In this context, halal foods a growing trend, trade estimated to cross USD $ 3 trillion and among this, meat sector contribute about US$ 600 billion. Halal meat and allied products is requirement from Muslims but it is also accepted by non-Muslims due to safe and hygienic nature, nutritious value and superior quality. Pakistan meat industry is vibrant and has seen rigorous developments during last decade as government also showed interest to boost livestock production and processing facilities to meet increasing local and global demand. The industry has potential to grow owing to its natural animal rearing capability, muslim majority country (96% of total population), improvisation of market and consumer preference towards halal meat. Current review debates Pakistan meat industry scenario, production trend, global trade as well as future potential with respect to modernization, processing, distribution and trade. The data presented here is useful for meat producers, processors and people involved in export of Pakistani meat and meat based products.

Home health care is one of the important components of health care services. Today, the need and demand for the home health care is increasing. To assess the effects of home visit health services by public health nurses in health center on the stat of health, use of medical services and quality of life by elderly people living at home, a randomized controlled trial was implemented for 65 years or more old people randomly allocated to intervention(93) and control(118) group. Intervention group received 2 visits a month over 6 months. Control group received no home visits. The data was collected in a one-year follow-up survey conducted at Kyongju before and after the intervention which composed of health risk assessment, risk factor education and health related behavior counseling. The prevalence rate of chronic illness was more decreased in intervention group than control group after intervention. The intervention group visited medical facilities less frequently than control group. And the home visit health services encouraged the elderly to practice regular exercise. After the intervention, the score of ADL(activities of daily living), LSI(life satisfaction index) and SSI(social support index) in intervention group were more increased than control group. And the increase of scores was more prominent in 70 years or more old people, female, non-smoker and non-chronic illed elderly rather than others. In conclusion, the regular home visit health services provided by public health nurses were beneficial for the elderly in terms of health promotion and quality of life.
