A survey was conducted from September 20 to October 2 in 2006, among worker's men and women. The 538 subjects were used to statistics, and the statistical analysis methods were frequency analysis, reliability analysis, factor analysis, t-test, and multiple regression analysis. First, a degree of media concern factors were determined to be media-advertisement concern, media-information concern. And a degree of appearance concern factors were determined to be appearance-styling concern, appearance-management concern. Second, a degree of media and appearance concern factors had an effect on appearance management of workers. Therefore, the more a degree of media and appearance concern was higher, the more appearance management was higher. Third, worker's women than men were shown to have many concern about media, appearance concern and appearance management.

The purpose of this study was to investigate the influences of appearance concern and body satisfaction on the appearance management behavior of male college students. For data collection, a questionnaire was administrated to 538 male college students in Gwangju city, Korea, from June 1 to June 20, 2011. To analyze the data, the SPSS 18.0 statistics package was used, and descriptive statistical analysis, factor analysis, reliability analysis(Cronbach' ${\alpha}$), regression analysis, path analysis, and t-test were conducted. The results were as follows. First, it appeared that concern of appearance had positive influences on the appearance management behavior. Also, there was a significant difference between the high-appearance-concern group and the low-appearance-concern group, as the high-appearance-concern group generally conducted greater appearance management behaviors than the low-appearance-concern group. Second, it appeared that concern of appearance had positive influences on body satisfaction, especially, on the aspect of face-satisfaction. Further, the results showed that the high-appearance-concern group seemed to have a higher body satisfaction than the low-appearance-concern group. Third, the result suggested that body satisfaction generally had positive influences on the aspects of appearance management behavior. Fourth, it was found that appearance concern had direct impact on the appearances management behavior without mediation body satisfaction.

It has been suggested that equity theory a social psychological theory concerned with the fairness in casual relationships should be applicable to marital relationships. This study describes the development of the scale for measuring perception of equity which measure the level of equity in marital relationships among Korean couples. PES(Perception of Equity Scale) is composed of two subscales; detailed measure of equity(DME) and global measure of equity(GME). The PES which include items from two areas of concern for intimates-pschological-emotional concern day-to-day concern-are describes. As results of test reliability of areas of DME range from .86 to .88 and reliability of GME is .92. And there are primarily evidences of construct validity of PES. Therefore PES is very reasonable scale to measure of equity/inequity perception in married couples. Finally analyzing of the level of equity in this sample husbands and wives has generally equitable relationships with their partn rs. Another findings suggest that husbands are overbenefited of their patners through marriage whereas wives are not.

The study investigates some psychological and environmental factors affecting the intention to purchase organic foods of consumers in the inner-city of Hanoi. Impact factors applied for the study include three psychological factors (health concern, environmental concern, consumer awareness of organic foods) and seven environment factors (family's opinion, friends and colleagues' opinion, influence of celebrities, expert's opinion, social status, mass media, state's encouragement). We analyzed research data from 396 consumers to measure the impacting level of these factors. The convenient sampling method was used to collect the research sample. The measurement applied a 5-point Likert scale classifying from 1-completely disagree to 5-completely agree. Based on previous studies, the research model was recommended. We had estimated the reliability of the scales through Cronbach's Alpha and composite reliability. The research data is analyzed by using Structural Equation Model method (SEM). The findings of the study suggest that psychological factors (health concern, environmental concern, consumer awareness of organic foods) had a significantly positive influence on consumer's purchase attention toward organic food. The results also revealed that environmental factors (family's opinion, friends and colleagues' opinion, influence of celebrities, expert's opinion, mass media) were positively linked to consumer's purchase attention toward organic food.

The Status quo of the reliability in China is described in this paper, a reliability surge is now spreading in China, covering the fields such as hardware, software, machinery and electronics. The reliability work in China was firstly conducted by the CEPREI Lab as far as early in the 1950s, and the reliability engineering in China has developed from the reliability of electronic products to that of machinery and non-electronic products, from hardware reliability to software reliability, from the attention to the reliability statistical test to emphasis on the reliability engineering test. Concern of Chinese companies about the reliability is the complete import of reliability engineering, the reliability testing, the software reliability and the reliability of lead-free soldering. Demonstration of reliability cases is given.

Modelling for failures is important for reliability analysis since failures of products such as automobiles occur as both time and usage progress and the results from the proper analysis of the two-dimensional data can be used for establishing warranty assurance policy. Hence, in this paper general issues which concern modelling failures are discussed, and both one-dimensional approaches and two-dimensional approaches to two-dimensional data are investigated. Finally non-parametric approaches to two-dimensional data are presented as a means of exploratory data analyses.

The purpose of this study was to measure the effects of food involvement and food neophobia moderating the relationships between vegetable consumption and health concern. The questionnaires with the items to measure constructs of health concern, food involvement, food neophobia and vegetable consumption were completed by 290 subjects in Jeonnam area. Moderated regression analysis was used to measure the relationships between variables. To test validity and reliability of constructs, factor analysis and Cronbach's $\alpha$ were used in this study. Results of the study demonstrated that the result of the analysis of the data also indicated excellent model fit. The main effects and interaction effects of health concern, food involvement and food neophobia on vegetable consumption were statistically significant. Moreover, the effect of health concern on vegetable consumption was statistically significant at all levels of food involvement and food neophobia, except when food involvement and food neophobia were high. The present findings may be particularly relevant to interventions to promote healthy eating among adults.
