      • 가로수 다양성 증진을 위한 수종 선정 방안 연구

        이규완,진상철 동신대학교 환경연구소 1998 환경연구 Vol.3 No.1

        현재 광주시에 식재되어 있는 가로수의 현황 및 추세를 분석한 후, 도시생육환경과 관련하여 과연 도시 가로수로서 타당한가를 선행연구와 문헌을 통해서 검토하였다. 또한 몇몇 수종 만으로 제한된 식재를 함으로써 식물생태상 가로경관의 단조로움을 초래하고 있는 상황에서 잠재력이 있고 개발 가능성 있는 수종을 선정기준에 의하여 점수화하는 방법을 제시하였다. 도시 가로수로서 적정수종을 선정하기 위하여 선정기준을 마련하고 수목의 생태적인 특성을 종합적으로 분석하여 배점기준을 마련하고 개량화 한 결과 도시내의 환경에 적합한 수종으로 은행나무, 느티나무, 양버즘나무, 튜립나무, 메타세콰이야, 단풍나무, 감나무, 칠엽수, 회화나무, 중국단풍 등을 제시하였으며, 그 외에 향토수종이면서 잠재력 있는 수종으로 이나무, 노각나무, 이팝나무, 팽나무, 느릅나무, 가중나무, 물푸레나무, 피나무, 쪽동백, 왕버들, 갈참나무, 신갈나무 등에 대하여 가능성 있는 수종으로 제시하였다. The purpose of this study is to show the diversity of species in street trees which brought about the simplicity of street landscape by planting some species and picking out more potential species from many native species which is appropriated to the street trees. In order to select the species appropriated to the street trees in the city. We choose the method which to giving about ten standard items using 31 species. Those are consisted in 16 species planting in the whole country, 15 species recommending from native species. The suitable species of the street trees in the cities, through they have some differences in environmental conditions. Namely, Ginkgo biloba, Zelkova serrata, Platanus occidenyalis, Liriodendron tulipifera, Metasequoia glyptostroboides, Acer palmatum, Dtospyros kaki, Aesculus turbinata, Sophora japonica and A. buergerianum. The possible species to the street trees in the cities. Namely, Idesia polycarpa, Stewartia koreana, Chionanthus retusus, Celtis sinensis, Ulmus davidiara var. japonica, Ailanthus altissima, Fraxinus rhyuchophylla, Tilia amurensis, Styrax obassia, Salix glandulosa, Quercus aliena and Q. mongolica.

      • 열역학 제2법칙에 의한 이중관 대향류 열교환기의 해석

        이근식,남궁규완 울산대학교 1991 공학연구논문집 Vol.22 No.1

        비압축성유체를 작동유체로 하고 뜨거운 흐름은 직렬이고 찬 흐름은 병렬로 된 이중관 대항류 열교환기에 대한 성능을 열역학 제1법칙적 관점과 제2관점에서 이론적 및 실험적으로 해석 하였다. 주어진 열교환기 형상과 입구조건에 대하여 펌핑동력에 대한 열교환량 및 엔트로피 생성율을 찬 흐름분율, 유량비열, 입구온도비에 대하여 계산하고 실험치와 비교하였다. 아울러 찬 흐름측을 직렬로 하였을 경우의 값들과도 비교하였다. The performance of the double pipe counterflow heat exchanger which uses an incompressible fluid as a working fluid and is connected in series on the hot side and in parallel on the cold side, was analysed both theoretically and experimentally in the view of 1st and 2nd law of thermodynamics. The ratio of heat transfer rate to pumping power and the rate of entropy generation for the given geometry of the heat exchanger and inlet conditions, were calculated and compared with the experimental results for the cold side fraction, the ratio of capacity rate, and the ratio of inlet temperatures of both sides. In addition, the ratio of heat transfer to pumping power and the rate of entropy generation were compared with those values of the case connected in series on the cold side.

      • 樹林下 野草類 植生의 生態學的 硏究

        李性圭,陸完芳 건국대학교 1979 論文集 Vol.10 No.1

        This study was carried out to compare herb vegetation of under Pinus densiflora, Larix kaempfer, Querecus mangolica forest and open herb vegetation. The results were following. 1.The standing crops of the vegetation under Pinus densiflora, Larix kaempfera, Quercus mangolica were 258.9g, 329.4g, 194.6g per 1m2 respectively. 2.The species composed of the vegetation under Pinus densiflora, Larix kaempfera, Quercus mangolica were 13, 16, 18 species respectively. 3.The standing crops of the grass land of hilltop, hillside, woodland were 47.8g, 148.7g, 274.7g per 1m2 and the species composed of vegetation were 13,14,13 species respectively. 4.Characteristics of the vegetations soils, especially, PH, avaliable phosphorus, and exchangeable Ca, Mg, K were not so differ from each studied vegetation. 5.Organic matter, total nitrogen were depend upon the forest which well developed and high standing crops.

      • Thiamine 誘導體의 摘出腸管에의 吸收에 관하여

        李琬夏,柳柄泰,智雄吉,朴大圭 成均館大學校 1980 論文集 Vol.27 No.-

        Thiamine-HCI, Thiamine Propyl Disulfide (TPD) and Thiamine Tetrahydrofur furyl Disulfide (TTFD) were studied to stability in artifcial gastric juice and artificial pancreatic juice. And in the in vitro isolated intestine of rabbit, absorption rate of this compounds were examined. The results were as follows. 1. The stability of this compounds in artificial gastric juice and artificial panereatic juice were stable. 2. In the in vitro isolated intestine of rabbit, absorption rate of TPD was increased than that of thiamine-HCI about 20% after 120 minutes. And absorption rate of TTFD was much the same in the case of thiamine-HCI.

      • 사회체육 동호인의 자아개념과 생활 만족도의 관계

        이제홍;김진규;김완기 순천향대학교 기초과학연구소 2010 순천향자연과학연구 논문집 Vol.16 No.2

        This study intends to offer the basic data by clarifying the relation between the self-concept of sport and leisure studies members' and the life satisfaction so that it can develop the social sports activities, spread them and improve the life quality through the righteous and useful leisure. In addition, the sound sport activities can be activated and the clubs can be expanded and finally contribute to improvement of the life quality, self- actualization, happiness, maintaining and improving heath. The sport club members in Daejeon have been set as a population and then the sample has been selected by a group sampling and a random sampling. In this study, total 360 sheets of questionnaire have been collected and 15 sheets have been eliminated because of their lack of confidence. Available 345 sheets have been inputted one by one, and the data processed by SPSS 14.0 for the analysis purpose. The specific conclusion is as follows. The self-concept of social sport club members and life satisfaction 1) The general, social, emotional and physical self- concept of members has a meaningful effect on the past life satisfaction. 2) The general, social, emotional and physical self- concept of members has a meaningful effect on the present satisfaction 3) The general, familial, emotional and physical self- concept of members has a meaningful effect on the future satisfaction.

        이규문,김종성,김태완 충북대학교 평생체육연구소 2000 平生體育硏究所 論文集 Vol.12 No.-

        The purpose of this study was to examine the effect of regular physical activity on the quality of life in the aged. The subject(69.22±6.43) in the study consisted of two group, one group(*****(p.68)=27) was regularly participating in physical activities, and the other group(*****(p.68)=25) was non-physical activity. This study used two questionaires: one for mental health(obsession, somatization, anxiety, interpersonal sensitivity, depression, hostility, phobic anxiety, paranoid ideation, psychotism) and the other one for life satisfactory(life satisfaction, happiness, morale). The subjects were completed the questionaires of mental health and life satisfaction before and after the 12 weeks. While physical activity group participated in the exercise program for 12 weeks, the other group didn't any physical activity. This study used SPSS package in processing data and found the mean and standard deviation, depending on each factor to analyze data ANOVA. The results of this study were as follows: First, there was a significant difference in obsession, somatization, anxiety, depression, hostility, phobic anxiety between physical activity group and non-physical activity group, except for interpersonal sensitivity, paranoid ideation, psychotism. Secoed, there was a significant difference in life satisfaction between physical activity group and non-physical activity group. It means that participation in physical activity is related to increase of life-satisfaction. Therefore, in order to have quality of life, the aged should be encouraged to participate in physical activities regularly because of the possibility of increased mental health and life satisfaction.
