The energy conservation in buildings affects environmental preservation as well as economic benefits, and creates the comfortable indoor environment set for the inhabitants. Especially, apartment buildings show ever-increasing energy consumption with large-sized and high-class tendency, thus energy saving counterplans are needed. The present study is to develop an optical control algorithm by using heating load curve according to the outdoor temperature change. Heating load analysis should be performed before the present method can be applied. Dynamic heating load simulations are performed by resistance-capacitance method. Results show that heating load decrease linearly according to the increase of outdoor temperature.

This study aimed to classify the lifestyles of 1020 college students, and to analyze the effect of the lifestyles on the usages of credit card, price perception, purchasing satisfaction and the number of new clothing. The number of credit cards, total payment of credit cards and the attitude to credit card were different by the 7 clusters of college students, but the frequency of credit card use, the amount of cash service and arrear ages were not different. The perception to the apparel price, purchasing satisfaction, and the degree of clothing purchasing varied according to the lifestyle clusters. For example, 6th cluster being highest in the pursuit of appearance showed the highest amount of credit cards usage significantly and tendency of highest arrearage, and used credit cards mostly in clothing purchase.

Recently, the market has been released a lot of excellent NVH performance cars such as hybrid, electric and luxury cars. Therefore, the consumer is a tendency of many sensitive of the noise inside the vehicle than in the past. In order to match the propensity of such consumers, the automotive industry defines the standard of product related to noise generation of a single product. However, it is difficult to reduce the noise of the product to automobile part suppliers to follow these standards. In this paper, we propose a method for evaluating several necessary in order to find a way to reduce the noise.

The purpose of this study was to develop the High Functional Stretch Yarns and Woven Fabrics to produce the high value added textile goods and to meet the consumer's needs. For the study 8 yarns and 10 fabrics were made with three develop machine and the thermal-stress properties of the sample were tested and analysed. The result indicated that the sample fabrics kept their stretch performance regardless of conventional process. EDY(elastic DTY) had higher stretch than that of DTY(drawn textured yarn). Especially Macel yarn had higher stretch than that of DTY compared with the same condition of yarn. With time course behavior the elongation of DTY and EDY had stabled tendency without variation. The above results show that wearing sensation and comfort properties of fabrics are changed depending on the end-use. and thus, above results can be used to manufacture of fabrics for specific end-use with high comfort properties.

Cultural needs of human have grown enormously. Consumer trend and individual taste have become more individualistic and diversified. Efforts to improve the quality of life have changed the concept of lift space as well as the concept of interior life supplies. Products are no longer standardized and produced in massive scale, thus a shift of value has risen. Damages done by the economical development have made consumers take interests in products that are more natural and in harmony with human beings. It is a tendency that wooden materials are becoming a preference as a specific alternative. There is a great social change with a new paradigm like this. Considering the change, we propose a new vision and activation plan on design development of wooden products through specific and practical studies by the system of educational and industrial cooperation which is an organic association system for developing human resources of educational system and producing profits of industry. From it, we can expect great effects as a competitive design of coming future.

Risk has been considered as one of very important topics in traditional consumer behavior theoretically and practically since its tendency of minimizing errors rather than maximizing utilization in addition to its intuitive appealing with very high explaining power. In addition to a traditional view of risk, importance of risk in online transactions such as Internet banking is due to technical instability in security of the Internet as well as temporal and spatial separation of transaction partners. Therefore, risk in online transactions should be analyzed by a very comprehensive way since it is very inherent in the Internet. The objective of this study is to suggest a research model for explaining the use of online transactions in some risk related variables including risk results, security result, perceived security, and social influence and show its validity by applying it to Internet banking users. In result, hypotheses suggested by our research model are shown to be valid ones.
