The change in a society have brought about other changes in the overall areas of culture and art. And have brought the advent of "object", which is a unique cultural aspect. The object became a trend of the world in a culture and art. This trend has satisfied the modern people who have look for new visual stimulation. The object appears well in the spaces restaurants and bars where are reflected in consumer's needs and change of life pattern. The reason is that the spaces restaurants and bars have expressed the differentiated and individualized image with the characteristic of the times. There are three types of the expressed characteristics of objects in interior design. These are visual, functional, and emotional characteristics. But in this study it could not be found that it characterized with one concrete vocabulary and concept. Therefore, it is need to understand the various tendency which expressed characteristics of objects in the spaces restaurants and bars.

When the product is removed from the mold after molding during the sheet metal molding process, elastic recovery causes a springback phenomenon. Much research has been done to minimize this phenomenon. In this study, V-bending experiments were conducted using galvanized steel sheets, stainless steel, and aluminum sheet materials, using a total of nine types of thin sheet materials of 1.0t, 1.5t, and 2.0t, respectively. Molding analysis and experimental data were compared and analyzed. In the case of galvanized steel sheets, it was considered that the springback phenomenon occurs more frequently in molding analysis than in experiments. It was considered that the springback phenomenon occurs greatly in the experiment, not the interpretation of the molding of the stainless steel plate and the aluminum plate. It was considered that the springback occurrence tendency of the molding analysis and the experiment was the same, and the springback occurrence error rate of the molding analysis and the experimental result was about 4.0%.

The purpose of this study is to analyze formative features of women shoes, to develop distinctive shoes design for coming fashion trend. the methods of this study are documentary research and case study. In the theoretical study, this study has catched the origin of shoes and the changes of shoes design of each era. for the study of formative features of women shoes in 1990's, 215 kinds of pictures have been selected from in professional shoes magazines. The results of analysis are as follow. Woman shoes categorized the design factors into shape, material, decoration. Reformational shape that reconstructs old shape of shoes by comtemporary aesthetic, shape in that dual images were mixed, re-created shape that was constructed through the reconstruction of structures and shapes of shoes. Material image was strengthened by varying patterns of unburned calf, leopard and zebra. Avant-garde was appeared by using naturalistic material to represent natural beauty or using merry, daring material. Post-modern tendency was appeared like using brassiere strap instead of back strap or using round string in elegant shoes.

Purpose: The aim of this study is to explore the psychological characteristics of users in mobile distribution channels (MDC) during mobile shopping. Research design, data and methodology: A conceptual framework based on shopping satisfaction theory was developed, leading to the proposal of a research model to examine the relationships between emotional control (EC), emotional practice (EP), prudential buying tendency (PBT), prudential buying urge (PBU), prudential buying behavior (PBB), and mobile shopping satisfaction (MSS) in MDC. To validate the research model, 125 survey responses were collected from mobile shoppers, and the relationships among EC, EP, PBT, PBU, PBB, and MSS were analyzed using the PLS structural equation model. Results: The empirical analysis revealed that EC did not have a significant impact on PBT, while EP had a significant effect on PBT. Moreover, PBT was found to influence both PBU and PBB, with PBU significantly affecting PBB. Finally, the study found that PBB significantly influences MSS. Conclusions: This study elucidates the relationships among EC, EP, PBT, PBU, PBB, and MSS, providing valuable insights for enhancing consumer shopping satisfaction in MDC. Practically, the study suggests various strategies for personalized and differentiated mobile customer management. Theoretically, it contributes to the field by stimulating further research on prudent purchasing behavior in mobile commerce.

Maximizing profit is the most significant object of commercial places. Especially for some places where its atmosphere is main concern of customers like $Caf{\acute{e}}s$, interior design is crucial. Thus it needs to evaluate human emotion and preference. Human Sensibility Ergonomics which is recently signified in various fields is an attempt to quantitatively analyze factors of human sensibility and apply it to design operation. This study attempted to infuse human sensibility ergonomics into $Caf{\acute{e}}$ interior design and analyzed preferable $Caf{\acute{e}}$ interior design factors. Because most $Caf{\acute{e}}s$ have their own target customers, so we assumed four different target customer groups divided by their age and gender groups in each age group. As a result, the difference of each group could be examined. Middle-aged group and males have main interest in the intensity of luminance, i.e. the brightness, whereas youths and females attach importance to both quality of light and color. In addition, there is a tendency for middle-aged group and males to see $Caf{\acute{e}}$ as a public place while young people and females recognize $Caf{\acute{e}}$ as a place for entertainment. Taking the result of this study into consideration can lead to successful $Caf{\acute{e}}$ interior design for specific target customers.

With increasing needs for affective design, it became an essential part in a product development process to look up quantitative ergonomic data that reflects customers' preferences on design factors in various products. This study looked at wide LCD monitors and analyzed customers' affective preferences regarding monitor's bezel frame size and shape. The monitor's bezel frame depth, size and ratio were selected as independent variables among many design parameters. As dependent variables, customer's subjective preferences were measured. A statistical analysis revealed that monitor's bezel frame depth, size and ratio had significant effects on customer's preferences. Also, it was possible to find a different tendency on affective variables and their levels for 19" and 24" wide LCD monitors. In general, experiments revealed that customers reacted more sensitively in 24" wide LCD monitors to all variables. In 19" wide LCD monitors, only the lower frame bezel size had a significant effect, otherwise, lower, upper and side frame bezels appeared to be effective variables in 24" monitors. In order to reflect customer's affective preferences to new design of wide LCD monitors, this study is expected to provide quantitative ergonomic data and guidelines for the design of wide LCD monitor's bezel frame depth and size.
