The purpose of this study is to develop systematic methods for evaluating the suitability of a seat and build an empirical model for predicting the suitability of a seat. The following research schemes were pursued to achieve the objectives - Development of suitable chair dimensions - Analysis scheme for decomposing the human-product interface system - Development of model for evaluating suitability. As a result, we uncovered six dominant suitability dimensions for the design of a comfortable seat that is related to the physical dimension of a body, Here, six suitability dimensions were identified as the dimensions that represent the human sensitivity and psychological feeling on comfortable seats. Also, 43 human-interface elements (HIE's) such as seat height, seat width, seat depth, tilting angle, seat surface etc. were investigated. HIE was generally defined as the physical characteristic of manufacturing goods, and it had close related to the body dimension of a user and environment that it was used.

Objective: This study aimed to identify profiles based on early childhood and elementary school teachers' goal orientations and to examine differences in teacher efficacy, psychological wellbeing, and job satisfaction among these profile groups. Methods: Data were collected through a teacher questionnaire. The teacher goal-orientation scale consisted of six sub-dimensions: growth, leisure, wealth, relationship, promotion, and social contribution. Data were analyzed using latent profile analyses. Results: Latent profile analyses revealed three distinct profile groups: one group characterized by higher scores across all six dimensions (balanced-goal-orientation group); another characterized by lower scores on all six dimensions, with a relatively higher score on the relationship dimension (relationship-goal-oriented group); another one characterized by lower scores on all dimensions except the leisure goal (leisure-goal-oriented group). MANOVA showed that the balanced-goalorientation group was significantly higher in total years of teaching, educational attainment, and age, compared to the leisure-goal-oriented group. In regression analyses, when controlling for educational attainment, teacher types (kindergarten vs. elementary school) did not significantly predict each of the dummy-coded profile groups (0 = no, 1 = yes). When taking into account teachers' age and educational attainment, belonging to the balanced-goal-orientation group was consistently associated with higher levels of teacher efficacy, job satisfaction, and psychological well-being, whereas the opposite pattern was observed in leisure-goal-oriented group. Conclusion: These findings imply that it is crucial to help pre- and in-service kindergarten and elementary school teachers foster a balance between different types of goals, which would ultimately strengthen and stabilize the supply of a teaching force and the provision of a better education.

The psychological work environments which facilitate technology innovations in organizations are divided into two dimensions of supportive work environments and uncertain work environments. The measurement variables have significant reliability. And the confirmatory factor analysis confirm the construct validity of two dimensional work environments. Two work environments have the significant effects on motivations to the technology innovations. So, simple and hierarchical regression analyses confirm criterion-related validity. Therefore, Both of the uncertain work environments(uncertainty of external-organizational environments and tasks) and the two important work environments(supporting idea, resource supply, job autonomy) are the two important psychological work environments which indicate technology innovations in organizations. Measures for innovative psychological work environments are provided.

Employing an ethnographic approach, this case study analyzed the psychological welfare of 2 teenage and one early-twenties heads of family. The subjects were Sun-Ju (female, age 22, seamstress), Ji-Hyun (female, age 14, junior high school student), and Seung-Hwan (male, age 16, junior high school student). This study was processed between 9 March 1996 and 11 May 1996. The results show that teenage and early-twenties heads of family have ambivalent feelings, meaning two extreme psychological conditions that are not consistent. Three types of teenage-early twenties heads of family ambivalence were caused by diverse role dimensions (e.g., nursing, supporter, beneficiary, and independent subject roles). Revision of the present welfare system, particularly the protection system For teenage-early twenties heads of family was recommended. Further research is also needed to determine various factors harmful to their psychological welfare.

This study investigates the benefits consumers seek in buying and using bedding, sub-dimensions of lifestyle, and the relationship between those of the benefits and the dimensions of lifestyle. This study conducted a survey to verify benefits consumers seek in buying bedding. A questionnaire was developed to collect data to measure lifestyle, benefits sought for the bedding, and demographic variables. Research was conducted on married women aged between 20 and 59. Total 294 responses were analyzed using factor analysis, correlation analysis, t-test, and one-way ANOVA with SPSS 18.0. A factor analysis identified three dimensions of benefits sought for the bedding: utilitarian benefits, social benefit, and aesthetic benefit. Lifestyle consists of five dimensions: health seeking, social symbol seeking, leisure/country-living seeking, aesthetics seeking, and economy seeking. All dimensions underlying benefits consumers seek in buying bedding and all dimensions of lifestyle were correlated. As consumers get older, they tend to seek more utilitarian and social/psychological benefits of bedding.

In today's rapidly changing environment, companies need to have proper strategies in place to meet the challenges that constant change presents. Being flexible, responding and adapting to changes can be valuable. However, they are essentially passive ways of dealing with situations. Creating new values and innovation are more active and effective strategies fora constantly changing environment. As such, most companies in e-business should focus on developing creativity across the board. Employees' creativity has become a critical factor in e-business. This paper explains how to increase workers' creativity through authentic leadership and psychological empowerment. As it is not machines or computers, but people, that are ultimately still responsible for creating novel outcomes, this study emphasizes the overriding importance of members' ability and leader's roles, which greatly influence followers' levels of motivation. Authentic leadership encourages members to reach and display their potential, and enhances their intrinsic motivation. Moreover, members' psychological empowerment is directly associated with both intrinsic motivation and autonomy, preconditions for creativity. Hence, these two dimensions- leadership and an individual's psychological state- will increase workers' creativity, which works to increase performance and create more opportunities not only at the individual level, but also at the team or organization level. The purpose of this paper is to explain the effects of authentic leadership on creativity and the moderating effects of psychological empowerment between authentic leadership and creativity in the e-business environment.

It is well known that irritable bowel syndrome (IBS) is related to psychological distress. However, only a few studies have investigated the relationship between IBS and various dimensions of psychological distress. This study aimed to evaluate the prevalence of IBS and its relationship with anxiety, depression, and stress in young female college students. A cross-sectional study was conducted using a self-report structured questionnaire with 673 female college students. IBS was diagnosed based on the Rome III criteria. For the evaluation of psychological distress on the IBS, we investigated Hospital Anxiety and Depression Scale (HADS) and Global Assessment of Recent Stress (GARS). The prevalence of IBS was 27.9%. In the univariate analysis, the anxiety, depression, and stress scores were significantly associated with IBS (P<0.001, P=0.001, and P<0.001, respectively). Multivariate analysis showed that anxiety (OR=1.07, 95% CI=1.01~1.15, P=0.032) and stress scores (OR=1.23, 95% CI=1.19~1.27, P<0.001) were independently correlated with the IBS. Among the subtypes of IBS, IBS with predominant constipation was the most common, and the anxiety, depression, and stress scores did not significantly differ between the subtypes. Our results suggest that anxiety and stress are closely related to IBS. Managing psychological distress should be considered in the treatment of IBS in young female college students.

In recent years, Korean society has witnessed an increased interest in the observance of everyday life proprieties, building healthy families, and psychological well-being of family members. The main purpose of this research was to examine the relationships among the practice of everyday life proprieties, dynamics of family systems, and psychological well-being of Korean married couples. A self-report Questionnaire was used to collect data from married couples with a child over four-years-old who are currently residing in Seoul. 513 couples(1026 individuals) were used for the final data analysis. Statistical analyses were conducted using frequencies, percentages, means, standard deviations, Cronbach'α, Pearson correlation, paired t-test, factor analysis, and multiple regression. The findings of this study are as follows: First, the level of the practice of everyday life propriety was relatively high in both husbands and wives, and no significant gender difference was found in the level. Yet, there were some statistically significant differences in certain sub-dimensions. Wives showed a higher degree of performance in public decorum and social etiquette, whereas husbands exhibited a higher degree of performance in family decorum and communication manners. The family systems were highly dynamic, according to both husbands and wives, and there was no difference between husbands and wives. As for the sub-dimensions, the extent of communication was found to be higher among husbands than among wives. Psychological well-being was again relatively high for both husbands and wives, with husbands significantly higher than wives. Second, the findings indicate that the causal model did fit the data well, and that a myriad of background variables had direct and indirect impacts on psychological well-being, and these relationships were mediated by several variables in the sub-dimension of proprieties observance, family adaptability, and the degree of communication. The implication is that the practice of life propriety, an intervening variable, is crucial in improving psychological well-being of married couples. The findings of this research demonstrate that there are significant causal relationships among the practice of everyday life propriety, family systems dynamics, and psychological well-being. In addition, the observance of proprieties is shown to be a concept that can be used as an important predictor in the area of family resource management. Further research is needed to expand its focus on the practice of proprieties in the family resource management. More concrete and specialized family life education programs should be developed to help build healthy families. Lastly, the results indicate that proprieties education needs to be incorporated in family policies in order to promote the quality of family life.

Biomechanical can physchological approaches have provided the optimum stair dimensions but physiological approach has never been used in assessing the common method of assessing the optimum stair dimension. Therefore, this study was conducted to investigate the validity of the physiological measure of heart rate in assessing the optimum stair dimensions. Sixteen subjects were asked to walk up three different stairs with their normal walking speed. The results showed that the physiological approach with the heart rate difference was found to be valid in assessing the optimum stair dimension. The optimum stair dimension from this study (riser length for 185 mm and tread length for 310 mm) was chosen because it was similar to optimum dimension by the psychological approach (Irvine et al., 1990).

The present paper describes the application of an improved impression transfer vector method (Sakurai et al., 2007) to transform the three basic dimensions (Evaluation, Activity, and Potency) of higher-order impression. First, a set of shapes and surface textures of faces was represented by multi-dimensional vectors. Second, the variation among faces was coded in reduced parameters derived by applying principal component analysis. Third, a facial attribute along a given impression dimension was analyzed to select discriminative parameters from among principal components with higher sensitivity to impressions, and obtain an impression transfer vector. Finally, the parametric coordinates were changed by adding or subtracting the impression transfer vector and the image was manipulated so that its facial appearance clearly exhibits the transformed impression. A psychological rating experiment confirmed that the impression transfer vector modulated three dimensions of higher-order impression. We discussed the versatility of the impression transfer vector method.
