In Human Reliability Analysis(HRA), the uncertainties involved in many factors that affect human reliability have to be represented as the quantitative forms. Conventional probability- based human reliability theory is used to evaluate the effect of those uncertainties but it is pointed out that the actual human reliability should be different from that of conventional one. Conventional HRA makes use of error rates, however, it is difficult to collect data enough to estimate these error rates, and the estimates of error rates are dependent only on engineering judgement. In this paper, the error possibility that is proposed by Onisawa is used to represent human reliability, and the error possibility is obtained by use of fuzzy reasoning that plays an important role to clarify the relation between human reliability and human error. Also, assuming these factors are connected to the top event through Fault Tree structure, the influence and correlation of these factors are measured by fuzzy operation. When a fuzzy operation is applied to Fault Tree Analysis, it is possible to simplify the operation applying the logic disjuction and logic conjuction to structure function, and the structure of human reliability can be represented as membership function of the top event. Also, on the basis of the the membership function, the characteristics of human reliability can be evaluated by use of the concept of pattern recognition.

The main purpose of this study was to investigate factors affecting performance of casual wear franchise stores including franchiser support and social network between owners/managers. The study included the franchise stores of 55 casual wear brands located in Seoul, Incheon and Gyeonggi-do. In each store, one manager, owner or staff member with management responsibility was asked to fill out a questionnaire. A total of 184 questionnaires were collected with 165 used in the final analysis. The results showed that franchiser support consisted of educational support, marketing support and customer support. Path analysis indicated that only the educational support had a significant influence on the franchiser-franchise relationship, and in turn, the franchiser-franchise relationship positively influenced customer performance. Marketing support did not have a significant influence on the franchiser-franchise relationship, but did demonstrate a direct influence on customer performance. Social networks positively influenced customer performance, and there was significant a correlation between regions and social networks on customer performance. Sales performance was significantly influenced by customer performance.

This study aimed to investigate the influence of mother's responsive/restrictive parenting and peer attachment on academic stress in school-aged boys and girls. The participants were 493 5th, 6th graders from five elementary schools in Daegu and Gyeongbuk province. The collected data were analyzed through a t-test, multiple regression, hierarchial regression using SPSS Win 19.0. The results are as follows. (1) Level of academic stress of school-aged girls was higher than boys. (2) Responsive parenting of mothers was the most powerful explanation in academic stress of school-aged boys. However restrictive parenting of mothers was the most powerful explanation in academic stress of school-aged girls. (3) In boys, responsive parenting of mothers influenced their academic stress but peer attachment didn't influence the boys academic stress. In girls, responsive parenting of mothers and peer attachment influenced their academic stress, and interaction effects of responsive parenting of mothers and peer attachment on academic stress was observed. (4) Both boys and girls, restrictive parenting of mothers and peer attachment had influences on academic stress. And interaction effects of responsive parenting of mothers and peer attachment on academic stress was not observed.

This study investigated the influence of children's emotional expression and sociability, and their mothers' communication pattern on their prosocial behavior. The participants were 65 preschool children aged between 5 and 6, and their mothers. Each child-mother dyad was observed for 30 minutes in a lab setting, which was designed to evaluate the child's socioemotional competence and the mother's socialization behavior. Videotaped data were analyzed by two coders for aspects of sharing behavior, the expression of happiness, sadness, anger, anxiety, and sociability for children, and mothers' communication strategies. Results showed that children's anger and anxiety expression were the most significant predictors for their prosocial behavior. Mothers' punitive communication pattern negatively affected children's prosocial behavior. However, when compared to the children's emotional expression, its' accountability were not significant. The influence of negative emotions, and its' adverse role in interpersonal interactions are discussed.

This study was conducted in order to understand grandmothers' intent of caring for working mothers' children and the influence of related variables with regard to living arrangements. The data was collected from 245 grandmothers who have been caring for their grandchildren for more than 6 months. The data was analyzed by mean, t-test, x2-test, and logistic regression analysis. The results were as follows: first, as to whether the grandmothers were willing to take care of their grandchildren again, 56.5% answered "yes", while 43.5% were not willing to do so. Those who were not living together with their grandchildren were more likely to answer positively. Second, it was found upon analysis that the significant variables of the experience differed according to grandmothers' residential status. In the case of co-residing grandmothers, the significant variables were the number and age of the grandchildren, their relationship, satisfaction, and feeling of burden, while only satisfaction was significant in non-co-residing grandmothers' cases. This implies that the more satisfaction the non-co-residing grandmothers experience, the more likely they are willing to take care of their grandchildren again. As for the co-residing grandmothers, it implies that the characteristics of the grandchildren, satisfaction, and feeling of burden, all influence their caregiving intent for the next time.

This study aims to 1) examine the difference of parent's participation intention for early childhood secondhand smoke prevention depending on sex, education level, income level, and smoking or nonsmoking of parent, parent's knowledge and attitude of early childhood secondhand smoke 2) estimate the influence of independent factors on parent's participation intention for early childhood secondhand smoke prevention centering around factors stated previously, and 3) suggest effective strategies to ultimately encourage parent's behavior for early childhood secondhand smoke prevention. A total of 279 parents with four- and five-year-old day care children participated in this study. The following are the main results of this study. First, the higher the level of income parent had, the higher the level of participation intention for early childhood secondhand smoke prevention parent had. Second, nonsmoking parent exhibited higher level of participation intention than smoking parent. Finally, parent's knowledge and attitude of early childhood secondhand smoke had influence on parent's participation intention for early childhood secondhand smoke prevention, but parent's attitude had a high degree of influence on parent's participation intention.

This study analyzed the impact of sense of self-efficacy on job satisfaction and organizational commitment among technical designers in order to acquire information needed for human resources management in the field of technical design. The study was implemented through a normative-descriptive survey method using a questionnaire. The sample consisted of 217 technical designers working at vendors and agents located in Seoul. The results revealed that there were significant differences in the sense of self-efficacy levels among technical designers according to age and work experience. Personal self-efficacy had a positive influence on both intrinsic and extrinsic job satisfaction, but also on affective, continuance, and normative organizational commitment. In addition, personal self-efficacy had a greater influence on extrinsic job satisfaction than social self-efficacy. Both personal and social self-efficacy influenced continuance commitment while there was no relationship between social self-efficacy and affective organizational commitment. However, a clear relationship was found between both social and personal self-efficacy and normative organizational commitment. Nevertheless, social self-efficacy had a greater influence on normative organizational commitment than personal self-efficacy. This fact demonstrates the need to exert more effort to promote the sense of personal self-efficacy of technical designers. These results could be used to provide appropriate proposals for human resources management in the field of technical design.

The purpose of the review article was to summarize and discuss the available information concerning the effect of bleaching on human teeth and reduced treatment on negative influence. Tooth bleaching effect was differ from extent of concentration and application period of a tooth bleaching agent, certainly full knowledge prior treatment about adverse effect possible appearance and follow clinical treatment for the least reduce. It remains unclear in how far those observation may result in significant adverse effect under clinical conditions. Nevertheless, further investigation are necessary to elucidate these aspect more precisely. The findings of the study were as follows : 1. It is recommended to delay placement of restorations after termination of bleaching therapy for at least 1-3 weeks. 2. Reduced negative influence that is clinical feasibility of catalase in protecting bleached surface against Oxygen radical. 3. The residual peroxide in tooth after bleaching seems to be removed by gradual diffusion and it may be possible to eliminate the adverse effect on tooth by using water displacement solution, ethylalcohol and aceton including it for effective removal of free radical oxygen.

The purpose of this study was to understand the interrelationships between customers' perception of service encounter elements, customers' emotional response and customer satisfaction in a family restaurant. Based on a total of 408 samples, this study reviewed the reliability and fitness of the research model and verified a total of 4 hypotheses using the Amos program. The hypothesized relationships of the model were tested simultaneously using a structural equation model (SEM). The proposed model provided an adequate fit to the data, ${\chi}^2$=821.151 (df=333), CMIN/df 2.466, GFI .878, NFI .927, IFI .955, TLI .949, CFI .955, RMSEA .060. The results showed that human factor ($\beta$=.426) and physical factor ($\beta$=.266) as service encounter elements in family restaurants were indicated to have a positive (+) influence on customers' positive emotion. For influence of customers' negative emotion, human factor ($\beta$=-.157) was surveyed to have a negative (-) influence. Also, customers' positive emotion ($\beta$=.716) and negative emotion ($\beta$=-.081) had significant effects on customer satisfaction. Limitations and future research directions are also discussed.
