박상일(Sang-Il Park),고창복(Chang-Bok Ko),이영수(Young-Soo Lee) 대한설비공학회 2017 설비공학 논문집 Vol.29 No.2

The heat transfer performance of a multi-heat-source fluidized bed heat exchanger was analyzed. The fluidized bed heat exchanger examined in this study can simultaneously recover the waste heat from gas, water vapor, and hot water. The effects of waste water flow rate, gas flow rate, and cooling water flow rate were examined to find their experimental correlations with the heat transfer coefficient. A computer program using the correlations was developed in this study to predict the thermal performance of the fluidized bed heat exchanger. The calculated heat transfer rates of gas, water vapor, waste water, and cooling water were compared with the measured values. It was found that the error of the calculated values was less than 12%.

The heat transfer performance of heating medium oil fluidized bed heat exchanger was measured. The operation variables were air flow rate, air inlet temperature, moisture content, water flow rate and water inlet temperature. The outside heat transfer coefficient was determined from the heat exchanger experiment and its experimental correlation was determined as a function of air velocity and viscosity of heating medium oil. Effect of viscosity was well agreed with the previous studies. Errors of the correlation equation was less than about 10% for outside heat transfer coefficient developed in this study when compared with the measured value. Hot water with the temperature greater than 77℃ could be produced by using the heating medium oil fluidized bed heat exchanger.

본 연구는 대표적인 그린제품 중 하나인 친환경 주부세제의 고객을 세분화하기 위하여, 그린제품의 구매동기 즉, 자기지향적 구매 동기와 사회지향적 구매동기 그리고 환경에 대한 관심을 세분화 기준으로 하여2단계 군집분석을 실시하였다. 그 결과 5개의 이질적인 세분집단인 ‘적극적 그린소비자집단’, ‘사회적 웰빙추구집단’, ‘비적극적 그린소비자집단’, ‘개인적 웰빙추구집단’, ‘비그린소비자 집단’으로 구분되었다. 그리고 5개의 세분집단들간의 인구통계적 특성과 고객충성도에 차이가 있는 것으로 나타났다. 이를 바탕으로 세분집단별 마케팅전략을 제시하였고, 학문적 시사점과 향후 연구방향에 대해 논의하였다. This study conducted a two-step cluster analysis to segment customers of eco-friendly dishwashing detergent that is one of the most representative green products of consumers’ purchase motivations consisting of self-oriented motivation, social-oriented motivation, and concerns about environmental issues. The results show that the customers of eco-friendly dishwashing detergents could be segmented into five clusters: (1) ‘active green consumers’, (2) ‘social wel-being seeking consumers’, (3) ‘passive green consumers’, (4) ‘personal wel-being seeking consumers’, (5) ‘non-green consumers’. Moreover, there were significant differences in demographic characteristics and dimensions of customer loyalty across the clusters. Based on the results, appropriate marketing strategies for each segment are suggested and theoretical implications and future research agenda are delineated.

The urban thermal environment can be an important index to detect heat island phenomena and manage it to improve urban life quality. Cheongju is a typical plain-city that main part has been formed and developed in lowland. The Mushim stream crosses the city from south to north. We reviewed the use of thermal remote sensing in stream around areas and the thermal environments, focusing primarily on the Urban Heat Island(UHI) effect. The purpose of this study is to determine the relationship between the stream nearby urban area and the stream cooling effect of UHI. The objectives are to determine the usefulness of KOMPSAT-2 bands MS3 and MS4 for vegetation cover mapping, and the usefulness of LANDSAT TM band 6 in identifying thermal environmental characteristics and UHI. Land Surface Temperatures (LST) are retrieved by single-channel algorithm to study the UHI from the 6th band (thermal infrared band) of LANDSAT TM images and thermal radiance thermometer based on remote sensing method and the LST distribution maps are accomplished according to the retrieval results. There is also comparison of satellite-derived and in situ measured temperature. The results indicated that the LST of urban center is higher than that of suburban area, the temperature of mountain and water are the lowest area, so it is clearly proved that there are obvious UHI effects by stream. The surface temperature distribution of Mushim stream is detected 2℃ lower than urban area.

그린제품의 속성에 대한 소비자의 태도와 품질 평가: 환경관여도의 조절효과를 중심으로

박상일 ( Sang Il Park ),천사라 ( Sa Ra Cheon ),김미정 ( Mi Jeong Kim ) 한국고객만족경영학회 2011 고객만족경영연구 Vol.13 No.3

소비자의 환경에 대한 인식이 커지고 있다. 많은 소비자들이 제품구매 시 환경적인 측면을 고려하며, 그린제품에 대한 높은 충성도를 보이고 있다. 제품의 속성과 이에 대한 소비자의 태도는 품질지각과 구매의도의 주요한 영향 요인이다. 그러나 그린제품의 관점에서 제품의 속성이나 품질 지각에 관한 연구는 많이 이루어지지 않았다. 따라서 본 연구는 그린제품의 속성에 대한 소비자의 태도가 품질 평가에 미치는 영향을 살펴보며, 그린제품의 속성에 대한 태도와 지각된 품질의 관계에 있어 환경관여도의 조절효과를 확인하고자 하였다. 연구결과 지각된 품질에 긍정적 영향을 미치는 그린제품의 속성에 대한 태도는 브랜드, 가격, 환경마크, 성분이고, 이 중 성분에 대한 태도가 가장 큰 영향을 미치는 것으로 나타났다. 아울러 지각된 품질은 고객만족과 고객충성도에 긍정적 영향을 미치는 것으로 나타났다. 그린제품의 속성에 대한 태도와 지각된 품질의 관계에서 환경관여도의 조절효과를 분석한 결과, 환경관여도가 낮은 경우 그린제품의 외재적 속성인 환경마크, 가격에 대한 태도가 지각된 품질에 미치는 영향이 크게 나타났고, 환경관여도가 높은 경우 그린제품의 내재적 속성인 포장에 대한 태도가 지각된 품질에 미치는 영향이 큰 것으로 나타났다. 이를 바탕으로 실무적 시사점과 학문적 시사점을 제시하였고, 연구의 한계점 및 향후 연구방향에 대해 논의하였다. As environmental awareness of consumers heightens, they consider the environmental-friendly aspects and exhibit a high degree of customer loyalty toward green products. The attributes of products and consumers` perception might be important factors that can affect consumers` product quality perception and purchase intention. Nonetheless, there are relatively very few studies that investigate consumers` attitude to the green product attributes - consumers` quality perception relationship. This study examines the relationship between consumers` attitude toward the attributes of green products and their quality evaluation. This research also tests the moderating effect of consumers` environmental involvement on consumers` attitude to the green product attributes-consumers` quality perception relationship. To test the hypotheses, we conducted a survey among female consumers in the Seoul metropolitan area who have purchased eco-friendly dishwashing detergents with environmental labels within the past six months. A total of 510 questionaries were utilized to conduct frequency analysis, reliability test, factor analysis, and structural equation model(SEM) with SPSS 15.0 and AMOS 7.0. The results suggest that consumers` attitude toward the brand, price, environmental label, and ingredient had a significant positive effect on consumers` perceived quality. The relative impact of attitude toward the ingredient on the perceived quality was the largest among the attributes of green products. Consumers` perceived quality had a significant positive effect on satisfaction and loyalty. Satisfaction also had a significant positive effect on loyalty. Furthermore, the results reveal that the positive effects of consumers` attitudes toward the extrinsic attributes - perceived quality relationship were higher for consumers with low level of environmental involvement than those of high environmental involvement group. On the other hand, the positive effect of consumers` attitudes toward a intrinsic attribute - perceived quality relationship were higher for consumers with high environmental involvement than the other group. Based on the results, theoretical and managerial implications are discussed in the last section.

The study was conducted to investigate the effects of Hydrangea macrophylla var. t1mnbergii extract on blood glucose and lipid concentrations in streptozotocin-induced diabetic rats. Experimental groups were classified into six groups, that is, normal control(Con) group, streptozotocin control(CI) group, Hydrangea macrophylla var. thunbergii(C2) group, hydrangea macrophylla var. thunbergii(50%) + polygonatum odoratum(50%)(C3} group, hydrangea macrophylla var. thunbergii(50%} + Cassia tora(50%)(C4) group, hydrangea macrophylla var. thunbergii(50%) + polygonatum odoratum(25%) + Cassia tora(25%)(C5) group. The blood glucose of C2 and CS groups decreased from 3 weeks. During 6 weeks, the weight of Con group increased S2.93% and C I group decreased S9%. The weight of C2, C3, C4 and CS group \vas 12, 27, 24 and IS%, respectively. The C2 group decreased the fewest. In the CS group, high density lipoprotein(I-IDL) cholesterol(47.4 ± 2.7 mg/dl) decreased the fewest and the triglycerides (63.9 ± 5.2 mg/dl) increased the fewest. Total cholesterol concentration of C2 group(63.8 ± 8.1 mg/dl) was lower t11an the C I group. In conclusion, it seems that Hydrangea macrophylla var. thunbergii extract has an effect on blood glucose, triglycerides, liver function protection etc.
