In retailing, it is very important to examine how consumers perceive and react to in-store design factors such as in-store space for walking, product arrangement styles, display types, and window sizes. Furthermore, consumers' perceptions to the various designs would be differentiated by consumers' shopping patterns such as actual shopping versus window shopping. This article investigates how various designs create different consumer reactions measured by consumer mood and store image depending on the types of consumer shopping (i.e. actual shopping vs. window shopping). It was found that design factors such as open, focused, and big created better consumer mood and consumer perception of store image than closed, unfocused, and small. Another finding is that consumer perceptions interact with consumer shopping patterns. Based on the research findings, managerial implications are also discussed

The purpose of this study is to evaluate the differences of visual effects and visual images by variations in shoulder angle and shoulder width of power shoulder jacket. The stimuli are 5 samples: One control group, 2 variations of the angle of shoulder line and 2 variations of the width of shoulder line. The data has been obtained from 87 fashion design majors. The data has been analyzed by Factor Analysis, Anova, Scheffe's Test and the Correlation Analysis. The results of the study are as follows: The visual images by the angle and the width of shoulder line of power shoulder jacket are composed of 4 factors : attention, stiffness and softness, masculinity, and trendiness. Among these factors, attention factor is estimated by the most important factor. The visual effects by the angle and the width of shoulder line of power shoulder jacket are composed of 3 factors : whole silhouette, neck and arm figure, upper body figure. In these factors, the whole silhouette is estimated by the most important factor. The power shoulder jacket with extreme changes in shoulder angle has double images: it looks trendy and classy but also gives an awkward image. In case of changes in shoulder width, the visual evaluation shows big differences with the degree of expansion. The visual evaluation with variation in angle has stronger image and effect than that in width. The power shoulder jacket trend itself is also evaluated that variation in angle reflects the trend better than that in width.

Recently there are increasing demands for establishing its peculiar city image in Korea. In establishing a urban image, streetscapes of various functional regions in city have very important roles. And many streetscape were designed and are under design for that purpose. There are many factors involved in the image-generation of streetscape, and the facade is one of the most important factors. In this study, we surveyed many factors in the city-regions of various functions to find out desirable characteristics of facade for each region. And we are going to use there findings as a basic data in the future streetscape design. We selected traditional region(Insadong, Chongro-gu, Seoul), apartment-type residential region (Apkujung-dong, Kangnam-gu, Seoul), and newly developed-downtown (Dunsan-dong, Seo-gu, Daejun) as streetscapes of various functions for facade study. Texture, color, form, size, structure and location of the following facade components were surveyed and analyzed. The surveyed components were window, entrance, equipment, signboard, show window.

The purpose of this study is about theoretical approach to scrutinize contents of spatial information and its communi-cating mechanism for revealing the interrelationship of architectural spaces and design factors in design process. It can be resulted that in architectural problem solving for adequate systemization of architectural spaces in specific conditions, intercommunication between social, psychologi-cal, perceptional aspects is important not so much as creati-ve design.

Human factors engineering design guidelines for main control rooms(MCR) in nuclear power plants(NPP) have been applied to optimize human-machine interface(HMI) between operators and their equipment on the basis of physical, physiological and cognitive aspects. However, the HMI design for MCR is not found to be sufficient to maximize operators' performance since the operators in the MCR experience excessive stress due to the environmental factors such as inappropriate interiors and illumination. Therefore, well-designed environment of the MCR may be equally important to improve human performance in the MCR. The objectives of the study are two-fold: (1) to propose an interior design of SHIN-KORI 1 2 for pleasant and comfortable working environments, and (2) to design indirect lighting system to enhance visibility and productivity. The human factors engineering checklists were developed to examine whether or not the proposed human-environment design for SHIN-KORI 1 2 satisfies the regulations and guidelines presented by NUREG-0700 Revision 1. The implications of the human-environment design are discussed in detail.

Domestic industrial complexes have more loss competitiveness due to their deterioration length and environmental problems. Therefore, it is necessary to suggest the direction of realignment as advanced industrial estates and establish new alternative plans for improving the quality of public and environmental designs as well as reinforcing the competitive power. This study examined the design planning factors affecting the service users' satisfaction in the Seoul Digital Industrial Complex through a PLS regression model. The research result showed that 12 crucial design planning factors out of a total 31 planning factors have a more than 1.0 VIP. In addition, 8 comparatively important planning aspects that were measured between 0.9 and 1.0 were also investigated. These factors were the strategic design planning factors estimating the quantitative priority while enforcing the design improvement project and they should be considered as a useful material for strengthening the competitive power of the Seoul Digital Industrial Complex.

This study investigated perceived discomfort and reasons related to use three information technology products (personal computer, mobile phone and digital television remote controller), and extracted the universal design factors. 240 people (30 females and 30 males for four age groups) participated in the one-to-one interview type of questionnaire, and replied to degree of discomfort at level of items and the reasons of discomfort at level of detailed elements for each product. As a result, almost all age groups answered that using input buttons of mobile phone and remote controller and watching display of mobile phone caused discomfort. Binary logistic regression of the detailed elements showed that response rate of discomfort mostly increased with age, except for specific elements such as shape of mouse and remote controller, and location of function button of mobile phone. Some of the detailed elements had high response rate of discomfort from all age groups. The age groups also showed similar tendency for the elements to select one alternative for the reason of discomfort, but not for sound volume and size of mobile phone and button sensitivity of remote controller. Finally, the universal design factors were extracted for each product based on the results, and divided into common factors and factors classified by the age group. Through this study, we identified using practices of various age groups and their demands for the products. It is expected that extracted detailed elements can be considered as important design factors to design the products universally.

Coolstore air relative humidity (RH) is an important factor affecting the quality of horticultural products, particularly via product moisture loss. RH also has an important effect on the performance of the refrigeration evaporators and can affect the strength of paper-based packaging materials. In a large New Zealand apple coolstore, RH increased from about 75% early in season to 90% at the end, as activities in the coolstore and external conditions changed. A steady-state analysis of sensible and latent heat entry and heat removal during four typical operational periods over the season was carried out. Predicted RH was in good agreement with measured dat. For the coolstore studied, evaporator surface area and the occurrence of pre-cooling within the coolstore were the design and operational factors having greatest effect on RH. Door protection and management, and floor insulation were the next more significant factors. The method of analysis has more general application and ould be used in a variety of situations so that design for optimum RH can be performed systematically.

The purpose of this study was to characterize the effect of Net fashion value regarding to the factors of purchase-decision at internet shopping mall and the preference for fashion design. The subjects for this sample survey, were junior high school and university students who had dwelled at pusan and ulsan in south korea. This study had 824 samples of each aged from 13 to 24 who had purchasing ability of fashion apparels at the interned shopping mal1. The sampling data in this survey was analyzed by frequency analysis, factor analysis, T-test, LSD-test, MANOVA and ANOVA of SPSS WIN package. The results of this study was as follows; 1. It was proved that advertising, pursuit of services and products, pursuit of information were considered first from Net generations fashion value. Next things were perception of danger and pursuit of convenience. It was proved that they considered it important A/S, recall, exchange and post management. 2. It was proved that there was difference at the preference for fashion design of according to Net generations fashion value. Color was considered to be the most important one. 3. Men had higher political value than women and 1318 teenagers had higher fashion value than semi-adult. Under high school educational course Net generation had more theoretical value than above university educational course Net generation did. Also, with the factor of average monthly income, political value was considered to be the most important. People whose monthly expenditure on purchase was above 50,000 won had higher social value than people whose expenditure was under 50,000 won but under 50,000 won had higher political value than above 50,000 won did.
