  • 본 논문은 기존 분산전원 신뢰도에 관한 연구를 기반으로, 여러 구역전기사업자로 인해 분산전원의 소유권과 수용가에 대한 전력공급 책임이 분리된 배전계통에 적용할 수 있는 신뢰도 해석기법을 제안한다. 구역전기사업자는 자신의 수용가에게 양질의 전력서비스를 제공할 의무가 있으므로, 계통사고시 자신의 분산전원 비상전력을 자신의 수용가에게 우선적으로 공급하는 비상대책을 선호한다. 기존 신뢰도 해석기법에서는 하나의 운영주체가 모든 전력원과 전력망을 관리하기 때문에, 여러 구역전기사업자가 존재하는 계통운영 상황에서 분산전원의 소유권을 별도로 고려하지 않는 해석결과는 실제 신뢰도 지수와 차이를 보일 수 있다. 본 논문의 사레연구에서는 RBTS 2번 모선에 2개의 구역전기사업자가 존재하는 경우를 모의하였으며, 기존 기법과 제안된 기법의 신뢰도 지수 결과를 비교하여 제안된 기법의 유효성을 증명하였다.

  • Tall building has some controversial aspects with low carbon city, but it is still a sensible choice for the metropolitan city. This paper aims to develop holistic urban design strategies to minimize impacts on the environment, increase energy efficiency and improve the quality of living in tall building communities by utilizing tall building characteristics. It puts forward the concept of integrated tall building-low carbon community design from the perspective of urban design, and summarizes five core strategies: Temporal state based on energy use, Complementary energy use state based on functions, Spatial state based on regional environment features, Transportation state based on low-carbon lifestyle and Waste utilization state based on tall building characteristics. It also applies the strategies to a practical project. The results show that the proposed urban design strategies are available approaches to mitigate the side effects of tall building on low carbon city.

  • Problems of housing, healthcare, social exchanges, and lonely feelings of vulnerable social groups such as the elderly living alone in rural and fishing villages should be resolved by guaranteeing minimum residential rights and levels to restore the sense of self-esteem and social stability and to maintain the rural communities and these should be the object of social interest and support. The housing problems of rural and fishing villages should be resolved not through supply to meet demand but by beginning with providing the ways to attain mutual interaction through the program that recognizes housing as merit goods to maintain the regional communities This research examines more minutely the problems caused by poor housing conditions of rural and fishing villages and attempts to present rural and fishing village type community living home as an alternative through regeneration. The results of this research are as follows. First, the administrative support system should be built to support the community living home in its beginning, process, completion, and even post management. Second, education for reinforcing capabilities to help understand the community living home should continually conducted on the occupants, villagers, and related organizations. Third, in order to expand the community living home, research and development should be made so that the zero-energy house, the alternative energy utilizing house, etc. can be widely used. In building community living home for vulnerable social groups in rural and fishing villages, practical alternatives suitable to the regional realities should be presented and practiced so that the community living home can be built to the satisfaction of all the villagers and the occupants, and the improvement measures should be presented through constant interest and monitoring.

  • This study was conducted to investigate the effect of an energy restriction program on the weight loss and changes of the biochemical nutritional status for 35 obese women. The energy restriction program took place over a 3-week period that was devided into two parts. The first part consisted of 750-800kcal diet and the second part of 800-1000kcal. Subjects were provided a low energy formula and a menu for the recommended diet. Anthropometric and biochemical measurement before and after the energy restriction program were estimated. Mean weight loss was 3.0kg, accordingly the obestiy rate was lowered from 40.2 to 34.4, BMI from 29.2 to 28.9 and fat weight from 23.3kg to 21.0kg( <0.01. <0.05). Waist circumference loss was most prominent(4.4%) compared to triceps(21% loss)and hip circumference(2.2%loss). Mean RBC count, hemoglobin and hematocrit were significantly lowered( <0.01) but they were in the normal range. Systolic blood pressure was significantly decreased from 124.1mmHg to 113.1mmHg . Mean SGOT and SGPT were lowered from 29.3u/L to 20.0u/L and from 28.7u/L to 16.6u/L, respectively. It seems that the 3 weeks of energy restriction program used in this study was effective in improving anthropometric measurements without producing deficiency of iron or other susceptible nutrients.(Korean J community Nutrition 2(5) : 695-700,1997)

  • The purpose of this study was to assess the energy value of breakfast and its relation to total daily nutrient intake and serum lipid. Dietary intakes were evaluated through the 3-day dietary recalls(interview for 1day and self-report for 2 days) from 333 Korean urban adults aged 20-49 year. Serum lipids in fasting blood samples were measured form 98 of those 333 adults. Low energy breakfast(<15% of daily energy intake) was consumed by 22.6% of males and 18.5% of females. 59.4 of males and 43.3% of females consumed a breakfast of average energy intake(15-25% daily energy intake) ; and 18.1 of males and 38.2% of females consumed a significant contribution to a total daily nutrient intake. The daily nutrient intake except crude fiber and vitamin A, B, B, and C in males and except vitamin C in females significantly increased as the energy value of breakfast increased. The differences in energy and nutrient intakes at breakfast were not made up for by other meals. To make matters worse, the satisfactory-energy breakfast group took more energy at dinner compared with the low-energy and average-energy breakfast group took more energy at dinner compared with the low-energy and average-energy breakfast groups in females. Among serum lipid parameters, TG was negatively correlated with energy provided at breakfast, and total cholesterol and LDL-cholesterol had a negative correlation with energy and carbohydrates provided at breakfast in males. For females TG was positively correlated with the ratio of carbohydrates to energy at breakfast but negatively correlated with the ratio of fat to energy at breakfast. These results suggest that satisfactory energy intakes at breakfast have positive effects on the adequacy of daily nutrient intake and may positively affect the serum lipid status.

  • Through 'The Renewable Energy 3020 Implementation Plan' for carbon neutrality, the government promised to raise the proportion of renewable energy generation to 20% and renewable energy installation capacity to 63.8% by 2030. Therefore, we plan to test a 5.5 MW offshore wind turbine near Maldo, Gunsan. In this project, we measure the level of public acceptance and perform ordinary least squares (OLS) regression analysis to show the determinants of public acceptance. The regression results are as followed. First, it is judged that the closer the distance to the offshore wind turbine, the more the economic effects considered by residents. Second, especially in Maldo, the experience of being discriminated from the Saemangeum project, is understood to have caused distrust in the surrounding fishing villages chief/Fisheries Cooperatives, converted into a local community effect. Finally, the policy implications are as follows. First, a bottom-up problem-solving method is required to improve public acceptance, based on the Living Lab. Second, the island community may be indifferent to the briefings or forums of outsiders. Therefore, a gradual approach is required through (in)formal channels based on reliability from a long-term perspective with nearby universities and research institutes using SamsØ Energy Academy.

  • Objectives: This study examined the effects of nutrition education focused on personalized daily energy requirement and food units using Food Exchange System on anthropometric, biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes for overweight and obese in a public health center. Methods: The subjects were 60 overweight/obese women based on BMI (educated 30 vs. non-educated 30, 50~64 years). Educated group was provided individual and/or group lessons (40 min/lesson/week, 5 week), 'Introduction: obese & health', '6 nutrients and 6 food groups', 'My obesity & daily needed energy', 'Meal planning for personalized daily energy and food units using Food Exchange Systems', and 'Smart food choices'. After education, we examined the differences in anthropometric/biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes between educated group and non-educated group. Results: After nutrition education, in the educated group, there were improvements on anthropometric/biochemical characteristics, nutrition knowledge, dietary attitude and nutrient intakes in the educated group compared to the non-educated group. We observed a decrease in the mean weight, total cholesterol (TC) and the incidence of overweight/obesity and hypercholesterolemia and an increase in the mean lean body mass. The scores of nutrition knowledge, 'Function of carbohydrate, protein, vitamin, mineral' and 'Food Sources of fat, vitamin, mineral' were increased. The scores of dietary attitudes, 'Taking a joyful meal, a leisurely meal, a balanced meal, a meal with sufficient vegetables, a meal with diversity, a meal with spicy foods, a meal with overeating' were increased. The intakes of energy, carbohydrate, fat, protein, vitamin A, thiamin, Zn and cholesterol were decreased. The scores of INQ, protein, vitamin A, vitamin C, thiamin, riboflavin, vitamin B6, folate, Ca, P, Fe, Zn were increased. Conclusions: The nutrition education focused on personalized daily energy requirement and food exchange unit using Food Exchange System for overweight and obese may improve food behavior, dietary intakes and symptoms of overweight and obese, even in a community health center.
