This research suggests a structural model of green purchase behavior, focusing on the moderating effect of affordability. Affordability means buying power or ability to buy products. Based on the literature review, a research model of behavior of buying green products was proposed and tested empirically using the field study. To examine the proposed research model, the reliability and validity verifications on measurement items were carried out and then the structural equation model analysis was applied to test the model. Lastly, to test the moderating effect of affordability, a two-group model(using Amos program) was used subsequently so that it could be determined whether or not there was any significant difference in structural parameters between the high affordability group and the low affordability group. The empirical results are as follow: Firstly, green purchase attitude is influenced by ecological concern and collectivism, then green purchase attitude has an impact on green purchase intention, and in turn, green purchase intention affects green purchase behavior. Secondly, affordability significantly moderates the relationship between green purchase intention and green purchase behavior. These results are consistent with the past researches and based on them, some managerial implications are given.

This study aimed to look into the Korean food consumption behavior, satisfaction, and loyalty between segmented groups through Korean food market segmentation in accordance with brand personality. A survey was conducted to the Japanese residing in Korea and also Japanese tourists in Korea. For the statistic analysis, frequency analysis, factor analysis, anova, $x^2$ and cluster analysis were conducted with Hangul SPSSWIN 19.0. The results of an empirical analysis include the following. First, the brand personality of Korean food was deduced into the following five levels: sincerity, ruggedness, competence, sophistication, and excitement. As a result of stereotyping based on the above, it was classified into three groups involving an excitement pursuing group (18.7%), a sophistication pursuing group (59.7%), and a competence sincerity pursuing group (21.6%). Second, it was found that there was a significant difference in the demographic characteristics and Korean food consumption behavior between segmented groups. Third, there was a significant difference also in satisfaction with and loyalty to Korean food between segmented groups. Specifically, competence and sincerity pursuing groups were discovered to exhibit the highest satisfaction and loyalty when compared with any other of the groups. Accordingly, it would be necessary to conduct a Korean food marketing strategy appropriate for each segmented group.

Recently, portion of the aged population has been increased, and aging became the biggest issue that we will be facing in the future. As the aging population has increased, the silver generation is getting to account for the considerable percent of economic activities and becomes the main body of production and consumption. Although the economic activity of silver generation is increased, the development of silver contents for the leisure activities is still not revitalized. The serious silver contents and the easy-to-use interface are very important because the silver generation is relatively weaker than young people in perception, studying, and exercise, and is fragile in mobility and vitality. This paper suggests the Sensory 3D Gate-Ball game for silver generation's leisure and health maintaining along with the easy-to-use interface.

The clustering environment with heterogeneous workstations provides the cost effectiveness and usability for executing applications in parallel. The load balancing is considered as a necessary feature for the clustering of heterogeneous workstations to minimize the turnaround time. Since each workstation may have different users, groups. requests for different tasks, and different processing power, the capability of each processing unit is relative to the others' unit in the clustering environment Previous works is a static approach which assign a predetermined weight for the processing capability of each workstation or a dynamic approach which executes a benchmark program to get relative processing capability of each workstation. The execution of the benchmark program, which has nothing to do with the application being executed, consumes the computation time and the overall turnaround time is delayed. In this paper, we present an efficient task distribution method and implementation of load balancing system for the clustering environment with heterogeneous workstations. Turnaround time of the methods presented in this paper is compared with the method without load balancing as well as with the method load balancing with performance evaluation program. The experimental results show that our methods outperform all the other methods that we compared.

쌀의 연간 생산량은 재배기술의 발달과 더블어 500만톤 이상을 꾸준히 유지해 오고 있는 반면에 식생활패턴은 점차 인스턴트화 되고 육류소비가 증가함으로써 1인당 소비량이 1990년 119.6kg에서 2002 년 87.0kg으로 급격히 감소하는 추세를 보이고 있다. 이러한 현상은 재고누적으로 이어져 2002년말 기준으로 1,190만석의 재고가 발생되고 있으며, 더욱이 WTO체제하에서 쌀시장 개방압력이 강화되고 있는 실정으로 앞으로 재고문제는 더욱 심화될 것으로 전망되고 있다. 이렇게 쌀이 남아도는 현실에서 국내 유통미의 품위는 싸라기 및 분상질립, 피해립, 이물 등 불완전립의 비율이 매우 높아 일본산이나 미국산에 비해 품질이 현저히 떨어지고 있어 고품질 가공을 통한 차별화가 시급히 요청되고 있는 실정이다. 따라서 본 연구에서는 최근 고품질 쌀 가공을 위해 설치 운영되고 있는 완전미 가공시설을 중심으로 완전미 가공기계장치의 구성 실태 및 제품의 품위 등을 조사분석하여 완전미 가공 기계장치의 개량요인을 도출하고, 이를 토대로 기계장치를 보완하기 위한 기초자료를 얻고자 하였으며, 그 결과를 요약하면 다음과 같다. 현재 보급되어 있는 완전미 가공시설의 구성형태는 기존 미곡가공시설에 홈선별기를 1대를 추가 설치한 제 I유형, 색채선별기1대 + 홈선별기 1대를 추가설치한 제II유형, 색채선별기 1대+입선별기 (개조) 1대를 추가한 제III유형으로 크게 나누어지고 있다. 이들 시설의 도정능력은 백미 가공시에는 I, II, III유형에서 각각 24.0, 27.7, 24.0톤으로 높았던 반면에 완전미 가공시에는 각각 3.1, 5,3, 4.5톤으로 처리능력이 크게 떨어지는 것으로 나타났다. 가공수율면에서는 일반백미로 가공시 72.0% 수준이었으나 완전미로 가공시에는 64.3%로 7.7%의 수율 감소를 가져왔지만 완전립률이 일반백미로 가공시 I, II, III유형에서 각각 89.08, 91.57, 88.00% 에서 완전미로 가공시에는 각각 98.02, 98.43, 97.78% 높아져 품질이 크게 향상되었다. 따라서 완전미 가공시설을 도입할 경우 쌀의 외관품질을 크게 높일수 있는 것으로 나타났다. 또 현재의 완전미 가공시설에 있어서 개량이 필요한 부분은 미숙립 등을 효율적으로 제거해 가공효율을 높이기 위해서는 입선별기의 개량이 요구되었으며, 홈선별기의 경우에는 선별정도는 문제가 없었으나 처리능력의 향상이 필요한 것으로 나타났다. 따라서 완전미 가공효율을 높이기 위한 선별기 개량연구를 계속 수행중에 있다.
