Purpose: The purpose of this study was to investigate the relationship between subjective quality of life and job stress with regard to general characteristics and health characteristics of physical therapists (PTs) and occupational therapists (OTs). Methods: The study involved administering questionnaires to 93 PTs and OTs who worked in urban medical institutions between November 2009 and October 2009. A questionnaire (KvSBQOL) developed by Dunbar and colleagues and translated into Korean version by Yoon et al was used for measuring subjective quality of life. A questionnaire developed by Kim was used for measuring job stress. Results: Among PTs and OTs, the mean quality of life score was 3.10 points and the mean level of job stress was 3.42. Female PTs and OTs had significantly greater levels of job stress. Those PTs and OTs in the 'Lowest pay' group and in the 'Associated Degree' group reported the lowest quality of life. Those in the 'Very healthy' group of PTs and OTs had significantly lower job stress than the other groups. The group with the highest job stress had the lowest quality of life. A limitation of this study was that all data was self-reported and subject to associated bias. Conclusion: To prevent loss of business services by PTs and OTs, it is important to know how job stress affects quality of life. Our findings suggest that a reduction in job stress can improve quality of life among PTs and OTs.

Pepper fruit anthracnose, caused by Colletotrichum acutatum, results in serious yield loss and affects crop quality in many Asian countries, making it a disease of economic consequence. A source resistant to C. acutatum was identified by the AVRDC within the line Capsicum chinense Jacq. PBC932. The resistant breeding line C. annuum AR is the $BC_3F_6$ generation derived from C. chinense Jacq. PBC932. The inheritance of resistance to C. acutatum was analyzed in segregating populations derived from the two crosses HN 11$\times$AR and Daepoong-cho$\times$AR. Detached mature green fruits were inoculated using microinjection method. The disease response was evaluated as the disease incidence at 7 DAI. The segregation ratios of resistance and susceptibility to C. acutatum in the $F_2$ and $BC_R$ populations derived from the two crosses fit significantly to a 1:3 Mendelian model. This indicates that the resistance of AR to C. acutatum is controlled by a single recessive gene.

Purpose: The purpose of this research is to study the role of life satisfaction, quality consciousness, and religiosity, which are integrated with the TRA Model to explain the switching intention of Muslim consumers to use Halal Cosmetics and Personal Care (HCPC). The second purpose is to investigate the relationship between variables used in this study to provide recommendations to HCPC producers about Muslim consumer behavior in the market. Research design, data, and methodology: The target population in this study is Muslims who live in Greater Jakarta. Data collection is carried out by the self-administered survey method based on the Purposive sampling technique, and the questionnaire is distributed online. The statistical analysis to test the research hypotheses is the Partial Least Squares - Structural Equation Model (PLS-SEM). Results: Life satisfaction, product quality consciousness, and religious commitment have a significant effect on attitude to switching but do not significantly influence the intention of switching to use HCPC. Conclusions: Life satisfaction, quality consciousness, and religiosity that represent individual factors indirectly affect the intention to switch to use HCPC. Thus, religious commitment influences attitude to switching both directly and indirectly.

Objectives : The objective of this paper is to clarify the factors of the geriatric oral health influencing oral health-related quality of life by using the contracted OHIP-14 tool. Methods : This research conducted individual interview for 177 seniors using senior citizen center by using structured questionnaires. SAS(Ver.9.2) Program was used for the collected data to perform frequency analysis, reliability and scale analysis, t-test, ANOVA, correlation analysis and multiple regression analysis. Results : The oral health-related quality of life level related to oral health according to the demographical characteristics showed that it was better in case that they are younger, married, more educated and have more living expenses. Except for age, oral health-related quality of life was connected to scholastic achievement, living expenses, subjective health condition and subjective oral health condition. The factors influencing the oral health condition were subjective health condition, marriage, scholastic achievement, living expenses, age and sex. As the subjective health condition is better, in case of cohabitation of only a couple and as the age or scholastic achievement is higher and the living expenses are more, the oral health condition was better. The factors influencing oral health-related quality of life were subjective oral health condition, marriage, sex, subjective health condition, scholastic achievement and living expenses. As the subjective oral health condition and health condition were better and in case of sole living and cohabitation of only a couple, male's oral health-related quality of life was higher. Conclusions : It is considered that because the geriatric oral health condition becomes an important factor to oral health-related quality of life, the development of the geriatric oral health business and the geriatric heal education program to maintain and improve oral health is required and the activation of the oral health insurance policy for preventive dental service is necessary.
