Objective: The purpose of this study is to examine the effects of oral exercise on oral function and denture satisfaction of the elderly using dentures. Methods: The study was conducted with targets of the elderly in the 13 senior community centers in Cheongsong-gun, Gyeongsangbuk-do from September 2013 to April 2014. The study subjects were divided into two groups, the intervention group provided with 8 week oral exercise program and the control group without exercise. The data on oral function, denture satisfaction and oral health related quality of life (OHIP-14) were analyzed among the 79 subjects from the intervention group and the 71 subjects from the control group. Results: For oral function, salivary flow rate, mouth opening, pronunciation and salty taste were significantly improved in the intervention group (p<0.01). There were significant differences in salivary flow rate, mouth opening, pronunciation and salty taste between the two groups (p<0.01). For denture satisfaction, there were significant differences in masticatory function, fixing function, general treatment satisfaction and total denture satisfaction between the two groups (p<0.05). There were significant differences between the two groups in the total points of oral health related quality of life. Conclusion: Oral exercise was effective in improving oral function and denture satisfaction of the elderly using dentures. To improve oral health related quality of life of the elderly further researches and programs will be necessary.

Objectives: This study was done to find out fatigue and self-reported physical symptoms of Vinylhouse farmers. The results of this study could be used as a basic data to develop health promotion program for Vinylhouse farmers who are suffering from fatigue and physical symptoms. Methods: The 166 respondents, who were working in Vinylhouse and were living in a remoted area where the primary health post located, were participated in this study. Thirty: 30 items of self-reported fatigue scale was used to evaluate the farmers fatigue level which made by Japanese industrial and hygenic association(1988). Twenty four: 24 items of index used by researcher for self-reported physical symptoms was from Lee In Bae's(1999) modified Index which was originated from Cornell Medical Index(1949). Another questionnaires used in this study were developed by researcher through related documents. Results: The results of this study were as follows; Fatigue scores were high in accordance with women(t=-2.212, p<0.05), worse recognized health state(F=20.610, p<.001), lack of sleeping hours(F=3.937, p<0.05), eat irregularly(t=-3.883, p<0.001), don't take a bath after application of chemical(t=-2.950, p<0.01), working time per a day(F=5.633, p<0.01) & working time per a day in Vinylhouse(F=5.247, p<0.01) were long. Subjective physical symptoms were high in accordance with women(t=-3.176, p<0.01), worse recognized health state(F=35.335, p<0.001), and low education(F=3.467, p<0.05). eat irregularly(t=-3.384, p<0.01), alcohol drinking(t=-2.389, p<0.05). When farmers don't take a bath after application of chemical show high(t=-3.188, p<0.01). As a result, the factors affecting to Vinylhouse worker's health were irregular diet habit, scarce exercise, lack of proper rest, symptoms oriented from Vinylhouse work in contaminated environment with high temperature and humidity.

To provide better health care services to the rural population, the government has made the Community Health Practitioner(CHP) a regular government official from April 1, 1992. This study was carried out to study the impact of officialization of CHP on the activities and management system of Primary Health Post(PHP). Fifty PHPs were selected by two stage sampling, cluster and simple random, from 595 PHPs in Kyungnam and Kyungpook provinces. Data were collected by a personal interview with CHPs and review of records and reports kept in the PHPs. The study was done for the periods of January 1-March 31, 1992 (before officialization) and January 1-March 31, 1993 (after officialization). Ninety-six percent of the CHPs wanted to become a regular government official in the hope of better job security and higher salary. The proportion of CHPs who were proud of their iob was increased from 24% to 46% after officialization. Those CHPs who felt insecure for their job decreased from 30% to 10%. Monthly salary was increased by 34% from 802,600 Won to 1,076,000 Won and 90% of the CHPs were satisfied with their salary, also more CHPs responded that they have autonomy in their work planning, implementation of plan, management of the post, and evaluation of their activity. There were no appreciable changes in such CHPs' activities as assessment of local health resources, drawing map for the catchment area, utilization of community organization, grasping the current population structure in the catchment area, keeping the family health records, individual and group health education, and school health service. However, the number of home visits was increased from 13.6 times on the average per month per CHP to 27.5 times. More mothers and children were referred to other medical facilities for the immunization and family planning services. Average number of patients of hypertension, cancer, and diabetes in three months period was decreased from 12.7 to 11.6, from 1.5 to 1.2, and 4.3 to 3.4, respectively. Records for the patient care, drug management, and equipment were well kept but not for other records. The level of record keeping was not changed after officialization. The proportion of PHPs which had support from the health center was increased for drug supply from 14.0% to 30.0%, for consumable commodities from 22.0% to 52.0%, for maintenance of PHP from 54.0% to 68.0%, for supply of health education materials from 34.0% to 44.0%, and supply of equipment from 54.0% to 58.0%. Total monthly revenue of a PHP was increased by about 50,000 Won; increased by 22,000 Won in patient care and 34,700 Won in the government subsidy but decreased in the membership due and donation. However, there was no remarkable changes in the expenditure. The proportion of PHPs which had received official notes from the health center for the purpose of guidance and supervision of the CHPs was increased from 20% to 38% during three months period and the average number of telephone call for supervision from the health center per PHP was increased from 1.8 to 2.1 times(p<0.01). However, the proportion of PHPs that had supervisory visit and conference was reduced from 79% to 62%, and from 88% to 74%, respectively. The proportion of CHPs who maintained a cooperative relationship with Myun Health Workers was reduced from 42% to 36%, that with the director of health center from 46% to 24%, that with the chief of public health administration section from 56% to 36%, and that with the chairman of PHP management council from 62% to 38%. Most of the CHPs (92% before and 82% after officialization) stated that the PHP management council is not helpful for the PHP. CHPs who considered the PHP management council unnecessary increased from 4% to 16%(p<0.05). Suggestions made by the CHPs for the improvement of CHP program included emphasis on health education, assurance of autonomy for PHP management, increase of the kind of drugs that can be dispensed by CHPs, and appointment of an experienced CHP in the health center as the supervisor of CHPs. The results of this study revealed that the role and function of CHPs as reflected in their activities have not been changed after officialization. However, satisfaction in job security and salary was improved as well as the autonomy. Support of health center to the PHP was improved but more official notes were sent to the PHPs which required the CHPs more paper works. Number of telephone calls for supervision was increased but there was little administrative and technical guidance for the CHP activities.

In rural area, as the source of family income is related with the agriculture works, the living condition of non-farming family used to be lower except some family groups with a little higher income. In order to find out the improvement in rural life, data about the health behavior and diet habits of non-farming family were observed. This study evaluated the health behavior and diet habits of non-farming families by comparing them with those of the farming families in rural area. The survey was made by trained interviewers and a total of 1,870 subjects from 9 provinces were questioned to collect the data through sampling probability proportional to size. The non-farming families were $29.6\%$ of the total and they were with no spouse($38\%$), low number of family members(2.86), and aged husband(66.8 years) or wife(58.5 years). $83.1\%$ of the non farming families were having breakfast however, $95.1\%$ of the farming families were doing it. And the number of side dishes in non farming families was low(1-2 kinds: $17.7\%$). Out of non farming families, $47.3\%$ took no nutritional supplements and out of the farming families it was 40.8 $\%$ With regard to having snacks, $22\%$ of non-farmers had snacks daily and it was greater than that of farmers($16.6\%$). But the ratio of non-snack taking of the non-farmers($29.6\%$) was higher than that of farmers($24.5\%$). The sorts of snacks also varied and for farmers it used to be fruit and noodles and for non-farmers it was bread and milk. Instant foods were often selected by $35.6\%$ of non-farmers. Dining out with a frequency of once per month was reported in $23.2\%$ of non-farming families, but $47.6\%$ of them did not dine out at all. In case of food production for family consumption, small portion of non-farmers cultivated pepper($13.3\%$), Korean cabbage ($16.2\%$), and sesame($6.2\%$) but almost all of the farmers cultivated such crops. However, non-farmers produced soybean sprouts($0.7\%$), soybean curd($0.2\%$), and eggs($7.2\%$) and it was compared with the fact that farmers produced soybean sprouts($9.7\%$), soybean curd ($4.6\%$), and eggs($5.1\%$). Non-farmers stocked the fermented foods: Doenjang ($57.8\%$), Kochujang ($56.1\%$), Kanjang ($53.6\%$), Kimchi ($77.9\%$) and Jangajji ($37.2\%$), and this ratios were smaller than those of farmers: Doenjang ($93.6\%$), Kochujang ($92.9\%$), Kanjang ($87.9\%$), Kimchi ($97.7\%$) and Jangajji ($66.7\%$). As to health behavior of the subjects, non-farmers had less medical examinations and bathing than farmers did. Non-farmers and their wives used public bath facilities more often and it may be due to the low condition of bathing facilities. And the ratio of daily alcohol consumption was $15\%$ and it was higher than that of the farmers. Most of the spouse of the farmers did not drink($78\%$), but the wives of the non-farmers were drinking more frequently. More farmers smoked than non-farmers and $45\%$ of male farmers were smokers.

Irrigation water supplied to the paddy field is consumed in the amount of evapotranspiration, underground infiltration, and natural and artificial drainage from the paddy field. Irrigation return flow is defined as the excess of irrigation water that is not consumed by evapotranspiration and crop, and which returns to an aquifer by infiltration or drainage. The research on estimating the return flow play an important part in water circulation management of agricultural watershed. However, the return flow rate calculations are needs because the result of calculating return flow is different depending on irrigation channel water loss, analysis methods, and local characteristics. In this study, the irrigation return flow rate of agricultural watershed was estimated using the monitoring and SWMM (Storm Water Management Model) modeling from 2017 to 2020 for the Heungeop reservoir located in Wonju, Gangwon-do. SWMM modeling was performed by weather data and observation data, water of supply and drainage were estimated as the result of SWMM model analysis. The applicability of the SWMM model was verified using RMSE and R-square values. The result of analysis from 2017 to 2020, the average annual quick return flow rate was 53.1%. Based on these results, the analysis of water circulation characteristics can perform, it can be provided as basic data for integrated water management.

In this study we examined the greenhouse worker's work load to test the efficiency of the developed vehicles (hand operated vehicle (HV), simple battery-powered autonomous vehicle (AV)). The subject of this study were healthy adult females who had experience in growing crops. We measured workers' heart rate, blood Pressure. rectal temperature, mean skin temperature, oxygen consumption and blood lactate level as a physiological index of work load. The results of this study are as follows : The test group using experimental vehicle showed the lower heart rate (mean$\pm$S.D. for HV, AV respectively 74$\pm$5, 75$\pm$3 beats/min, p＜0.01) than the control group (84$\pm$8beat/min) not using experimental vehicle and the lower systolic blood Pressure (HV, AV respectively 109$\pm$8, 109$\pm$9 mmHg, p＜0.01) than the control group (121$\pm$11 mmHg), and lower rectal temperature(HV, AV respectively 37.0$\pm$0.1, 36.8$\pm$0.2$^{\circ}C$, p＜0.01) than the control group (37.0$\pm$0.2$^{\circ}C$), and the less oxygen consumption (HV, AV respectively 2.13$\pm$0.09, 1.66$\pm$0.52$m\ell$/kg/min, p＜0.01) than the control group(2.43$\pm$0.12$m\ell$/kg/min), and the lower blood lactate level (HV, AV respectively 2.03$\pm$1.00, 1.66$\pm$0.52mmol, p＜0.01) than the control group (2.43$\pm$0.12mmol). Judging from these results, these experimental vehicles for greenhouse workers can be confirmed as a useful tool. It is suggested that these vehicles would alleviate the peasant's syndrome including muscle fatigue and musculoskeletal disease usually caused by working in an uncomfortable posture.

This study was performed to investigate the effects of dietary calcium on blood and tissue lipids of adult rats fed a high fat diet with or without supplemental cholesterol for 4 weeks. Male Sprague-Dawley rats were fed the experimental diets containing 18%(w/w) beef tallow and three levels of calcium 0.1%, 0.5% and 1.5%. The contents of total lipid, cholesterol, triglyceride and phospholipid in blood, liver, small intestine, aorta, small intestinal contents and feces were determined. Only in rats fed the diets containing 1% cholesterol the concentration of cholesterol in aortic serum and various tissues significantly increased, and then decreased with increasing dietary calcium intake. Another observation was that high Ca intake significantly facilitated the fecal lipid and cholesterol excretion and bowel movement. These results suggest that possible hypocholesterolemic effects of dietary calcium could be related to the hypercholesterolemia and to the increase in excretion of fecal lipid and cholesterol.

This study examined the effect of the pine needle sap administration on serum lipid composition and liver antioxidant defense system in rats fed with high fat diet. Forty eight male Sprague-Dawley rats were divided into six groups. three control groups were fed with 5% lipid diet and three high fat groups were fed with 30% lipid diet. Each group was administered with the following pine needle sap respectively : C-0.0, 1.ml water, C-0.5, 0.ml pine needle sap and 0.ml water C-1.0, 1.ml pine needle sap : H-0.0, 1.ml water, H-0.5, 0.ml pine needle sap and 0.ml water H-1.0, 1.0ml pinus needle sap. After 4 weeks of experimental periods the level of serum obtained and serum lipid was measured respectively. The results were as follows 1. Significant low level was observed for food intake, weight gain, FER in the experimental group administered with the pine needle sap. 2. No difference of the concentration of serum triglyceride was observed out the experimental group with 5% fat diet, however out of the experimental group with 30% fat diet it was low in (H-1.0) group where 1.0ml of the pine needle sap was administrated. 3. In the experimental group with 5% fat diet the concentration of serum total cholesterol and LDL cholesterol was low, especially the hypocholesteromic effect in serum administered by the pine needle sap was significantly high in group C-1.0 where 1.0ml of pine needle sap was administered. In the high fat group provided with 30% fat when the pine needle sap was administered there was a tendency that concentration of total cholesterol and LDL cholesterol decreased however there was no difference significantly. 4. Serum GOT activity was relatively high in high fat diet group. However, when 1$m\ell$ of pine needle sap was administered the activity was lower than that of the control group in H-1.0 group and the activity level was similar with that of the high fat diet group in c-1.0 group. There was no difference of serum GPT activitives followed by the administered of pine needle sap among the experimental group. 5. Liver TBARS levels were high in general in high fat diet group, however it showed no difference when the pine needle sap with different concentration level was administered. The results of this study indicate that the pine needle sap administration was effective in decreasing the food intake and weight gain of the experimental animals in the high fat diet and also effective in decreasing the levels of serum triglyceride, total cholesterol and LDL cholesterol and GOT activities. However it was not effective to change the level of TBARS and GSH -Px activities of liver. Thus, it was found that the pine needle sap administration was effective for the improvement of serum lipid composition condition of the experimental animals in the high fat diet group but it was not effective in the antioxidant defense system of liver.

This study is aimed at developing a nutritional task of a community' as a public health activities of Su-Dong Myun, Demonstration Project area of Ewha Womans University. The content of this study is the points of nutritional diagnosis for the residents nutritional evaluation, the analysis of the related factors and the educational material with Nutrition Education-Index. Two hundreds housewives were examined during the period of Jan. 20 to Jan. 30 in 1989. 1. In terms of the housewives' age, those aged 30 to 39 were 32.5% which was the highest and educational level, graduation of primary school was 31.5% which was the highest. The housewives who had no job were 60.0% and those who participated in community activities were 56.5%. 2. In terms of the points of nutritional diagnosis, 50 to 74 points were 51.5% which was the highest and total average was $65.1{\pm}15.0$. 3. As for the points of nutritional knowledge, the average was 54.9 points, attitude was 77.4 points and eating practice was 70.8points. 4. The number of clinical symptoms of nutritional deficiency was 16.1 ones per person. 5. As for the relation which nutritional knowledge, attitude, eating practice exert on one another, nutritional knowledge has negative correlation with eating practice(-0.04) and attitude has some correlation with eating practice(0.17). 6. The variable having to do with the points of nutritional diagnosis showed the highest correlation coefficient(0.55) as the points of nutritional knowledge. 7 As for the variable having to do with the number of the symptoms of nutritional deficiency, the higher points of knowledge(-0.05) is, the higher the totai averse points of nutritional diagnisis(-0.09) is, negative correlation was appeared. 8. The result in which the variant having to do with the number of clinical symptoms of nutritional deficiency was analyzed by multiple regression analysis showed that the lack of time for preparing meals in non agricultural households made the greatest contribution (9% explained) and the households having vegetable garden made the second greatest contribution(3% explained).
