This study is to explore how consumers' needs for tactile cues affect their purchasing behaviors in the internet shopping mall. Since previous studies about internet shopping malls are mainly performed on the primary factors of perceived risk, there are insufficient studies of tactile cues for apparel products. Emphasis of this study is placed on verifying the following hypothesis; it is expected that consumers' needs for tactile cues affect apparel purchasing behaviors in internet shopping. The questionnaire was administered to 20 to 30 year old male and female respondents who are either students or businessmen living in the Busan area. 150 questionnaires were completed and collected for data analysis. The data were, using SPSS 10. 0 for Window, statistically analyzed by frequency and factor analysis for VARIMAX, Cronbach's coefficient and Linear regression analysis. Data were, using SPSS 10. 0 for Window, statistically analyzed by frequency and factor analysis for VARIMAX, Cronbach's coefficient, and ANOVA. The results of data analysis are as follows: First, the tactile cues negatively affect purchase intentions of consumers. This shows that apparel internet shoppers who have high desire for tactical cues tend to avoid purchasing products through the internet. Second, the factor analysis of the moderating effect on perceived risks shows that the perceived risks significantly moderate both the tactile cues and purchase intention of consumers. Third, analysis of purchased experience also shows that purchased experiences significantly moderate both the tactile cues and purchase intention.

^x This study was executed to measure the user's psychological carrying capacity in the National Park Campsite in the district of Temple Ku- Ryong as a model of analysis, which is made socio - psychological approach. The results are as follows ; 1. Since this Place hart a beautiful scenery and some cultural assets prosperties and lies near the metroplitan area, 67.5% of the user come from the district, such as Seoul, Inchon, Kyong - Ki Do, and the purpose of camping is to appease their stress and to promote friendly relationship one another. 2. Since most of the campers(86%) didn't recognize the injury of the natural environment, the enlightment movement and the public information for the protection of natural environment are urgent. And they thought that the good campsite is located near the stream(43.6%) or a quiet place(33.4%). 3. As the space per a man increase, the degree of their satisfactions showed the tendency to increase. The user's satisfaction were analyzed by three statistic methods, correlation, multiple regression and factor analysis. Affecting factors to the user's psychology by the varimax varimax rotated factor analysis were classified physical arts ecological satisfaction. 4. The carrying capacity of the campsite by the degree of psychological satisfaction of the user was measured. The result was that the proper space for one user campsite was 35m$^2$ 5. The 58% of the informants said that they root disturbed by the overcrowding in the campsite. But most of the users thought that it was not good to control the number of the users. And the 67.3% of the respondents answered that the best method was that we control the number of the users by order of arrival if we have to control it.

Background: Work-related fatigue has a strong impact on performance and safety but so far, no agreed upon method exists to detect and quantify it. It has been suggested that work-related fatigue cannot be quantified with just one test alone, possibly because fatigue is not a uniform construct. The purpose of this study is therefore to measure work-related fatigue with multiple tests and then to determine the underlying factorial structure. Methods: Twenty-eight employees (mean: 36.11; standard deviation 13.17) participated in five common fatigue tests, namely, posturography, heart rate variability, distributed attention, simple reaction time, and subjective fatigue before and after work. To evaluate changes from morning to afternoon, t tests were conducted. For further data analysis, the differences between afternoon and morning scores for each outcome measure and participant (${\Delta}$ scores) were submitted to factor analysis with varimax rotation and each factor with the highest-loading outcome measure was selected. The ${\Delta}$ scores from tests with single and multiple outcome measures were submitted for a further factor analysis with varimax rotation. Results: The statistical analysis of the multiple tests determine a factorial structure with three factors: The first factor is best represented by center of pressure (COP) path length, COP confidence area, and simple reaction time. The second factor is associated with root mean square of successive difference and useful field of view (UFOV). The third factor is represented by the single ${\Delta}$ score of subjective fatigue. Conclusion: Work-related fatigue is a multidimensional phenomenon that should be assessed by multiple tests. Based on data structure and practicability, we recommend carrying out further studies to assess work-related fatigue with manual reaction time and UFOV Subtest 2.

The purpose of this study is to find out the factors that explain the sense of touch and preference of man-made leather. Date base of descriptors for man-made leather was collected by interviewing 50 consumers, 33 different kinds of commercial man-made leathers(synthetic leather and artificial leather) were assessed subjectively by 605 consumers using the 9-point scale of 34 pairs of bipolar descriptors based on the data base. Subjective ratings were analyzed by principal axis factoring with varimax rota-tion. The sense of touch of man-made leather is explained by five factors ; surface property stretchiness thickness& weight thermal property(warmth & coolness) and moisture property (sticky & clingy). The difference in the sense of touch of man-made leathers is mainly attributable to surface property and stretchiness. And the preference of man-made leathers is mainly attributable to surface property and stretchiness. And the preference of man-made leather is explained by three factors ; surface property stretchiness and quality. Higher preference is found in man-mad leather of better quality touch and softness.

The purpose of this study was to examine the characteristics of consumer evaluative criteria based on clothing quality perception of adult males and females. A demonstrative study was conducted using a questionnaire on adults over 20 years old who were considered to afford to purchase clothes. A total of 650 questionnaires were distributed, and among them, 380 were used for the demonstrative analysis. The study used SPSSWIN V.8.0 for the analysis. Factor analysis and reliability analysis were introduced as analysis methods using the varimax rotation to classify consumer evaluative criteria for clothing purchasing. In addition, frequency analysis, correlation analysis, 1-test, multiple regression analysis, and duncan test are executed. The study result is as follows. First. expectation, importance and performance are examined by customer quality perception. Four factors- practicability, care, aesthetics, and symbolism- are classified through the factor analysis of 19 evaluative attributes based on importance. Second, differences of quality perception f3r expectation, importance and performance were found partly in customers' demographic characteristics. Third, the influential relation of satisfaction and quality perception is examined. Aesthetics and practicability have significant influence on the general satisfaction of evaluative attributes by performance.

Statistical analysis technique was applied to operating parameters and removal efficiency data sets obtained from advanced wastewater treatment plant during 1 year. Through factor analysis three factors derived varimax rotation were selected each plant. Three components explained 96%, 87% of the total variance of the process, respectively. The components on $A_2O$ Plant were identified in the following order : 1) Shortening the SRT during high-flow period, 2) Keeping biomass high on winter 3) factor was related to DO. On DNR plant, we defined them as follows: factor 1, Prolonged the SRT during high-flow period; factor 2 was related to sludge return; factor 3, Influent BOD during low-DO period. This technique was believed to assist operators in identifying priorities to improve operation efficiency.
