In this study, we performed long lange power transmission expansion planning for conceptual design of HTS power cable in Seoul area. Since the HTS power cable has the high power transmission density and low loss characteristics in comparison with conventional power cables, the HTS power cable is introduced between the downtown and the suburbs in the future system in order to verify the feasibility of the HTS power transmission cables technically and to encourage the research activity in the area.

The first purpose of this study is to build the most effective leisure farming model after classifying them by type, and secondly to examine about how realizing implementation measure of the model. At this time since leisure farm, leisure orchard and leisure ranch were thought as most important types, model for these types was made actually. Three regions in the suburbs of Taejeon city were chosen as proper site in the process of modeling. Methods and contents of public activities for promoting leisure farming were suggested concretely as a measure of carrying out leisure farming plan.

This study was investigated to evaluate whether brown rice drying could reduce the rice production cost. Characteristics of brown rice drying was experimentally determined. With brown rice drying, the higher energy efficiency could be obtained. Therefore, this method is effective to cost reduction . However, there are some problems , for example occurrence of fissuring and preservation of rice quality.

수도권에서 보고된 리기다소나무 생장감소의 원인을 밝히기 위하여 33장소의 리기다소나무 숲에서 교목의 밀도, 수령 및 토양의 물리화학적 특성을 조사하였다. 토성을 제외하고 토양의 물리적 특성들은 도심지와 전원지에서 차가 없었다. 그러나 토양의 pH값, 염기포화도 및 염기성 양이온 함량은 전원지에 비해 도심지에서 낮았지만, 수용성 Al 함량과 S함량은 그 반대였다. 도심지의 토양산성화는 산성강하물에 의한 영향으로 해석된다. 다중회귀분석 결과, 수도권에서 리기다소나무 생장은 토양의 가비중<토양의 Al 함량<교목의 밀도<토양의 Mg 함량<수령의 순으로 영향이 컸다. 결론적으로 수도권에서 리기다소나무 생장의 감소는 1차적으로 토양산성화가 주요한 요인이었을 것으로 판단된다.

광주근교 경작지 토양 53점의 유기염소계 살충제 8종의 잔류분을 분석(分析)하여 다음과 같은 결과(結果)를 얻었다. 1) Dieldrin을 제외한 7종(種)의 유기염소계 살충제(有機鹽素系 殺蟲劑)의 잔류분(殘留分)이 60% 이상(以上)의 시료(試料)에서 검출(檢出)되었다. 특히 ${\alpha}-BHC$는 거의 모든 시료(試料)에서 검출(檢出)되었으며 p,p'-DDT의 잔류수준이 가장 높았다. 2) 논 토양보다는 밭 토양에서 높은 오염률(汚染率)과 높은 잔류수준(殘留水準)을 보였다. 3) 경지정리답과 미정리답의 유기염소계 살충제의 잔류수준은 차이가 거의 없었다.

전남 도내 5개 지역과 광주시 근교 1개 지역에서 재배되고 있는 미나리의 안전성 평가를 위해 중금속 함유량과 기생충 감염 여부를 조사하였다. 그 결과 비교적 독성을 지니고 있는 중금속인 수은과 비소는 각각 흔적 수준과 극히 미량인 $0.003{\sim}0.01\;ppm$으로 나타났다. 납은 모든 지역에서 검출되지 않았으며, 카드뮴은 $0.013{\sim}0.036\;ppm$ 범위를 보였으며, 또한 농작물 생장에 필수원소로 작용하는 구리, 망간과 아연의 함유량은 $0.285{\sim}0.627\;ppm,\;1.337{\sim}12.884\;ppm,\;2.105{\sim}4.221\;ppm$이 검출되었다. 또한 미나리에서 흡충류인 간질과 간흡충, 수인성원 충류인 람블 편모충과 크립토스포리듐속 그리고 선충류인 회충과 십이지장충 6종에 대한 기생충 검사 결과 모두 검출되지 않았다.

This paper has attempted to improve the quality of urban environment in terms of the management of urban green tract and suggest a way of coexistence between human and nature by proposing a plan to establish green network using an urban green zone based on 'linear concept' instead of point and plane concepts. The results have turned out as follows: 1. According to current status of forest functions, forest recreation area has reached 39.6%, satisfying citizens' needs. However, the space for living environment is just about 20% with a lack of a green zone. Therefore, it's been necessary to establish green network using roadside trees and take advantage of them as sustainable living space along with existing green tract. 2. With forest in the suburbs and Geumhogang which is the tributary to the Nakdonggang, Sincheon (stream) flows through the downtown. It connects mountains including Waryongsan from the south to the north around Duryu Park and Dalseong Park. Therefore, the water system that passes through Palgongsan (Mt.) and Biseulsan (Mt.) would make it possible to connect with the parks in the downtown. 3. According to this paper, it appears that it's necessary to establish green network through roof or wall greening by focusing on the existing green tract in the urban parks and suburbs and taking advantage of roadside trees and water system.

The purpose of this study was to assess dietary intake and food habits of low-income person aged 60 years or eldary. The hundred fifty persons from the suburbs of Jeonju were surveyed between August 1 to 20,1979. Results were as follows: Family environment Approximately 90% of elderly persons surved, lived with their children and grand-children: 5.2% together as a couple; and 4.4%, widowed, lived alone. Nearly 40% of the households has a average monthly incomes of W40,000 to W100,000. Average food expediture accounted for 50 to 70% of total monthly income, thus indicating that the subject families belonged to the lowest socioeconomic level. As pocket money, 74.5% of male subjects had more than W5,100 per month. whereas, 51.4% of female had less than W5,000. Anthropometric measurements: 97.6% of subjects has heights greater than 90% of the Korean standard for their age group, whereas 45.2% of the subjects were 60 to 89% of standard weight. 88% had an arm circumferences only 60 to 89% of the standard. Nutrient intake: Intake of the majority of nutrients was below the recommended allowances, especially for energy, protein, calcium and iron. The energy input ratio of carbohydrate: protein: fat was 73.1-80.9. 13.3-15.8: 4.5-11.5, showing very heavy dependence on carbohydrates for energy needs. The contribution of animal protein was 24.3% of total protein intake, indicating an improper protein diet. Other factors influenced on the nutrient intake: Poor teeth, illness, and poor appetite were always associated with inadequate intake of energy and nutrients. The larger the family size, the lesser intake of nutrients was observed among those elderly.

This study selected commonly known species of fruit trees, and re-selected the species that endure the stress of extreme cold weather and physiologically restore themselves to the previous state until the following year. Then we could go ahead to propose the species that were appropriate as urban greening plants in weather condition of any part of the country. To do this, we conducted an experiments for six species of fruit trees based on the preference of the general public and recommendation of the experts; Morus alba (English name: mulberries), Diospyros kaki (English name: Persimmon), Prunus persia (English name: Peach), Elaeagnus umbellata var. coreana (English name: Korean Autumn Olive), Malus domestica 'Alps Otome' (English name: Alps Otome), and Prunus mume (English name: Blue Plum). The experiment verifies whether the trees survive without any stress from the cold weather under the national climate conditions (one in the suburbs of Seoul: Yongin city, one in the central Chungcheong region: Daejeon city, and in the southern Gyeongsang region: Jinju city in Korea). The experiment lasted for a year from August 2016 to August 2017. The levels of electrolytic efflux, chlorophyll content, plant height, fresh weight, and dry weight were measured four times (on August of 2016, January, February, and August of 2017) for each tree planted bare ground outdoors. Results showed that Diospyros kaki, Prunus persia, and Malus domestica 'Alps Otome' were proven durable and resistant to winters of all three areas (one in the suburbs of Seoul: Yongin city, one in the central Chungcheong region: Daejeon city, and in the southern Gyeongsang region: Jinju city in Korea). Especially, the increase of chlorophyll content and the reduction of electrolytic efflux were noticeable in Prunus persia than in the other two species, proving itself as the most cold-tolerant among the six species used in the experiment. In addition, interpreting from the physiological restoration data of one-year span before and after getting through winterer, Prunus persia was proven to be the most cold-tolerant species.
