A well-designed location strategy is an integral and important part of corporate strategy for retail firms The last five years witnessed major changes in retailing industry A growing city population, rising income levels, and the emergence of suburb areas presented retailers with new challenges Mass discount merchandisers and supermarkets expanded rapidly, spreading from Seoul into smaller cities The rapid increase of mass discount stores raised new concerns and gave rise to the need from a systematic approach to location analysis in this paper, we present the mathematical background and characteristics of DEA(Data Envelopment Analysis) model, and give a short case study where we apply the DEA model to compute the relative efficiency of 11 Korean mass discount merchandisers interpretation of the result is also provided

생활체육 테니스 참가자의 참여정도에 따른 여가만족 및 생활만족에 관한 연구

김승철,이동현,육영숙,장선웅 한국스포츠심리학회 2003 한국스포츠심리학회지 Vol.14 No.3

본 연구는 생활체육 참가자의 사회인구학적 특성과 참여정도에 따른 여가만족과 생활만족의 차이 및 관계를 비교 분석하여 생활체육 테니스의 참여 기회확대와 활성화를 위한 기초자료를 제공하고자 한다. 이와 같은 목적을 달성하기 위하여 2002년 서울시 S구 소재의 생활체육 테니스 시설을 중심으로 테니스 활동에 참가하는 만20세 이상 성인을 모집단으로 무선표집된 10개소 테니스 시설에서 총 300명을 집락표집(cluster sampling) 하여 생활체육 테니스 참가자의 참여정도에 따른 여가만족 및 생활만족의 각 변인간 차이를 분석하였다. 그 결과 사회인구학적 특성변인에 따른 여가만족에서는 남자가 신체적, 사회?교육적, 환경적 요인이 여자보다 높게 나타났고, 연령에서는 연령이 높아질수록 신체적 요인이 증가하는 것으로 나타났으며, 고연령 집단에서 사회?교육적 요인, 환경적, 휴식적 요인이 높게 나타났다. 교육수준에서 신체적 요인은 교육수준이 높을수록 만족 요인이 증가하는 것으로 나타났으며, 수입에서는 고수입 집단이 신체적, 사회?교육적, 휴식적 요인이 높은 것으로 나타났다. 또한 연령은 높고 수입이 많은 집단에서 생활만족이 높게 나타났으며, 참여정도에 따른 여가만족에서는 참여기간이 증가할수록 사회?교육적, 환경적, 휴식적 요인이, 참여시간에서는 참여시간이 증가할수록 신체적, 사회?교육적, 환경적, 휴식적 요인이 높아지는 것으로 나타났다. 생활체육 테니스 참가자의 여가만족이 생활만족에 미치는 영향과 인과 관계에서는, 사회?교육적, 환경적 요인이 생활만족에 가장 많은 영향을 주는 것으로 나타났으며, 마지막으로 생활체육 테니스 참가자의 참여정도(기간, 빈도, 시간)에 따른 생활만족에서는 참여기간, 참여시간에서 유의한 차이가 있는 것으로 나타났다. 참여기간과 참여시간은 각각 기간과 시간이 증가할수록 생활만족이 높아지는 것으로 나타났다. 본 연구의 결과와 다수의 선행연구 결과들의 차이는 변인 및 요인의 다양성에서 비롯되는 것으로 사료되며, 참여정도와 생활만족의 관계를 설명하는 보다 많은 연구가 필요하고, 생활만족에 관련한 변인과 하위 요인을 정확히 측정하고 신뢰할 수 있는 도구와 일관성 있는 결과들이 지속적으로 제시되어야 한다. This study was to examine differences and relationship between life and leisure satisfaction of sports participants based on socio-demographic groups in order to broaden participation opportunities in tennis as well as to provide fundamental data for further studies. To achieve its main goal, 300 subjects of this study were selected among adults tennis participants over 20 at 10 tennis facilities located in Seoul in 2002 by means of multi-stage stratified cluster sampling method, and were analyzed factors of leisure satisfation and life satisfaction depends on degree of participation of tennis participants. The result shows that physical, socio-environmental, educational factors of male participants indicated higher than those of women. Older participants showed higher physical factor, and the aged group indicated high socio-educational, environmental, relax factors. As the educational level was higher, the satisfaction factor increased, and high income group showed high physical, socio-educational, relax factors. The age and high income group expressed high life satisfacton, and as participation period and time become longer, socio-educational, environmental, relax factors became higher. There was also cause and effect relationship between leisure and life satisfaction, and socio-educational, environmental factors were main factors. Lastly, life satisfaction was stastically different depends on degree of participation (period, frequency, time), and longer participation period and time lead to higher life satisfaction. However, this study and some previous studies are contradictory in some ways. It is considered that those conflicting results stem from various factors and variables, thus consistent insturments and reliable results should be created through further studies on degree of participation and life satisfaction.

水狀態土壤中 室素의 行動에 關한 硏究 : 第1報 湛水靜置狀態下에서 土壤의 깊이에 따른 室素의 變化 Changes of Nitrogen in the Water-logged Condition with Soil Depth

IIn order to investigate the fate of nitrogen in the submerged soil, Suchang, Hwasoon and Susan soil which have different properties, were treated with several fertilizers, such as ammonium sulfate, ammonium chloride, urea and SCU(mlfer coated urea), and incubated under water logged condition in 30 ℃ incubator. pH. NH₄-N₂?? NO₃-N and Fe?? in the soil and stagnent water, were determined at 5, 10, 15, 22, 30 and 60 days after incubation. The obtained results were summarized as follows. 1. pH of the stagnent water was 8~8. 5 in the urea plot and 6 ~ 6. 5 in the (NH₄)₂SO₄and NH₄C1 plot during the incubation. 2. PH content of the Suchang and Hwasoon soil was increased rapidly in the early stage of incubation, but that of Susan soil was increased gradually with the incubation period. It seemed that the change of Fe?? content depended on the organic matter of the soil. 3- NH₄-N content of stagnent water of all three sample soils was decreased gradually along the incubation period. 4- The amount of NH₄-Nin the soil on which NH₄Cl or(NH₄)₂SO₄was applied, was increased as the incubation periods while decreased in the urea plot. 5. NO??-N was determined in the stagnent water, and soil, but its content was changed irregularly during the incubation. 6. It seemed that NH₄-N in the stagnent water from the (NH₄)₂SO₄ or NH₄Cl could be absorbed gradually by the soil, but that from the hydrolysis of urea could not be absorbed by the soil. 7. In accodance with the above results, it was thought that nitrogen of NH₄C1 or (NH₄)₂SO₄ in the paddy soil was lost by the denitrification, but the nitrogen of urea was lost by both the denitrification and ammonia volatilization.

해저형상에 따른 연안유속분포형상

김웅용,윤영호,연기석 大田産業大學校 1997 한밭대학교 논문집 Vol.14 No.1

This paper aims at the elucidation of the characteristics of longshore current profile after wave breaking. Wave breakers are always accompanied by complex turbulent process, wave energy losses and the mean water level variations due to the gradient of radiation stress. These processes with other factor result in the development of longshore currents. Because longshore current have relation to the alongshore sand transport on a bed and, to the diffusion of contaminants nearshore region, the understanding and elucidation of longshore currents are very important from tile engineering point of view. The longshore currents induced by simple wave striking an planar beach, nonplanar beach, and barred beach are calculated.

Preferences on the change of color and aroma of soybean sprout was surveyed. Negative response of 'bad' or 'very bad' on pink (72%), red (60%), and green (44%) coloring was obtained. However, yellow coloring showed about 55% of positive response of 'good' or 'very good'. Thus yellow is the only color which received highly positive response among altered-color soybean sprouts. Significantly different result was observed when various aroma was added to soybean sprout. 80% of peanut scent-added soybean sprout and 76% of melon scent-added soybean sprout received positive response of 'good' or 'very good' while only 20% of the reponse was negative. In conclusion, altering color to yellow and addition of peanut scent or melon scent could increase the general preference of soybean sprout.

구리이온을 함유하는 천연 제올라이트상에서 암모니아에 의한 일산화질소의 제거

김영걸,황웅천,나민식 한국화학공학회 1990 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.28 No.1

국내 영일군에서 채취되는 천연 제올라이트에 구리이온을 첨가시켜 (CuNZA) 일산화질소를 암모니아로 선택적으로 제거하는 공정의 개발이 고정층의 흐름반응기에서 합성 배기가스를 사용하여 연구되어 졌다. 천연 제올라이트에 구리이온을 첨가시키므로써 반응속도가 100배 이상 증가되어 졌고 이 반응속도는 촉매의 구리 함량에 관계없이 합성 제올라이트(CuHM)와 유사하게 일산화질소의 농도에 대해 저온 영역에서 (200-370℃) 1차 속도식으로 잘 표현되어 졌다. 촉매상의 최적 구리 함량은 무게비로 3% 정도이다. 또한 CuNZA 촉매는 표면적, 기공분포와 Si/Al비와 같은 천연 제올라이트가 갖는 특이한 물리화학적 성질로 인해 이 공정의 가장 취약점 중의 하나인 유황성분에 대한 촉매활성저하 현상에 강할 것으로 기대되어 진다. Selective removal of NO by NH₃ on natural zeolite from Young-il, Korea with various copper loadings (CuNZA) has been studied in a packed bed flow reactor system with simulated flue gas. Two orders of magnitude increase in the reaction rate were achieved by the addition of copper ions to the catalyst. The first order, irreversible kinetic model with respect to NO concentration adequately fits experimental data for this reaction system as did for synthetic mordenite zeolite system (CuHM) over the low reaction temperature (200-300℃) covered, independent of the copper level. The optimum copper content is aboue 3wt%. It is expected that CuNZA catalyst will have stronger sulfur tolerance than CuHM because of its typical physical properties such as surface area, pore size distribution and Si/Al ratio.
