Background: This study aimed to examine the effectiveness of role-play in dental hygiene education by analyzing learners' perceptions and experiences of role-play classes. Methods: Role-play was used as a teaching method to run dental medical communication and practice classes for 31 3rd graders in the Department of Dental Hygiene to investigate the learner's perception of role-play classes, effectiveness of the classes, and learner's perception of the experience. The Mann-Whitney U test was used to analyze the differences in learners' perceptions of the role-play classes according to the main characteristics related to dental health communication education. Results: The correlation coefficient between awareness of dental communication education (4.74 ± 0.35) and awareness of role-play classes (4.44 ± 0.48) was an Rs of 0.634, showing a significant positive correlation (p<0.001). Conclusion: Learners recognized that dental hygiene communication competency is important for dental hygienists. In addition, a strategic teaching design is necessary to reduce the learner's burden on role-play considering the learner's experience, which is perceived as a disadvantage of role-play

This paper is to research the difference of care workers' role in Sanatorium between urban and rural areas. Interviews have been conducted with 100 care managers with structured questionnaires in community care settings. The findings of the study are as follows. In the analysis of working with carers a care manager acting as a counsellor in rural was required rather more than any other role in working with clients' carers. In working with formal and informal networks, an administrative specialist role was also important in both areas. With resource management, there were some regional variances between rural and urban. In the urban area, a care managers as a coordinator was more required than as a broker. In the rural area, a care manager as a broker, selecting service resources for elderly clients was the most suitable role. In conclusion, in general rural care managers' roles were similar to those of many core managers in urban area. Among the many possible roles of care managers that effective continuity of care is to be provided for elderly clients in community care, two have been specified as essential roles. The first is the role of care managers that provides coordination and integration of services at the clients' levels as a care manager as an implementer, a linkman, counsellor. The second is at the system level which is possible role for coordination and linkage of programs as a characteristics of care managers, task with formal & informal network, community resources, available residential & NHS resourcesw.

Purpose: This study was done to investigate differences in maternal role confidence and parenting stress according to the infant's feeding method. Method: The participants were 257 mothers of infants aged 5$\sim$7 months. 145 breast-feeding mothers and 112 bottle-feeding mothers participated. The Maternal Role Confidence Scale and Parenting Stress Index(PSI) were used. Results: The score of maternal role confidence of breast-feeding mothers (3.28) was significantly higher than that of bottle-feeding mothers(2.84). In addition, the parenting stress level of breast-feeding mothers(1.80) was lower than that of bottle-feeding mothers(2.97). However, the scores of maternal role confidence and the parenting stress level were not different according to the mother's and infant's personality characteristics. There was a significant negative correlation between the score of maternal role confidence and parenting stress levels(r=-.55, p<.001). Conclusion: Breast feeding mothers had more confidence of their maternal role, and a lower parenting stress level. Therefore, nurses must encourage infant mothers to breast feed since it is the best option for mothers as well as infants.

The purpose of the study was to examine the effect of sex role orientation on the amount of time spent in meal preparation and cleanup, clothing care, and indoor cleaning accomplished by husbands and wives in couple-headed households in the U.S.. The overall research hypotheses examined were : (1) there is a relationship between demographic and socioeconomic characteristics of the husband and wife and the sex role orientation of the husband and wife; (2) for both husbands and wives, there is a relationship between sex role orientation and the amount of household production time that is accomplised by each individual; and (3) the relationship between sex role orientation and the amount of household production time remains when demographic and socioeconomic factors are controlled. The 1981 data from the 1975-1981 Time Use Longitudinal Panel Study collected at the University of Michigan were used for this study. The major findings is that a relationship between sex role orientation and the amount of time spent in three household production activities was not found, when all independent variables were controlled. That is, sex activities was not found, when all independent variables were controlled. That is, sex role orientation was not a predictor affecting the amount of time that husbands and wives spend on meal preparation and cleanup, clothing care, and indoor cleaning.

The emerging competitive environment in today's global marketplace is one where businesses no longer compete with each other as autonomous, individual firms. Global, economic, and technological development pressure forces organizations to continually enhance their performance through knowledge sharing and innovativeness. The purpose of this paper is to explore the moderating role of knowledge sharing and the mediating role of innovativeness in the relationship between transformational leadership and organizational performance. The data was collected from 389 employees in Vietnamese industrial enterprises through a questionnaire survey. The information was then analyzed by explanatory factor analysis (EFA) confirmatory factor analysis (CFA) as well as structural equation modeling (SEM). The results show that the mediating role of innovativeness and the moderating role of knowledge sharing in the relationship between transformational leadership and performance, are supported. Organizations may reap the benefits of an innovative workforce by selecting, nurturing transformational leaders. This study contributes to the field of human resources management, particularly leadership, by exploring the role of transformational leadership. Moreover, this is the first study to test the moderating role of knowledge sharing and the mediating role of innovativeness in the relationship between transformational leadership and the organizational performance.

Eosinophils are terminally differentiated cytotoxic effector cells that have a role in parasitic infections and allergy by releasing their granule-derived cytotoxic proteins. However, an increasing number of recent observations indicate that eosinophils are not only associated with the pathogenesis of a wide range of diseases, but also contribute to the maintenance of homeostatic responses in previously underappreciated diverse tissues, such as the gastrointestinal (GI) tract and adipose tissue. In this review, we describe biological characteristics of eosinophils, as their developmental properties, permissive proliferation and survival, degranulation activity, and migration properties enable them to distribute to both homeostatic and inflamed tissues. We describe pathologic aspects of eosinophils with a role in asthma and in various GI diseases, including eosinophilic GI disorders, inflammatory bowel disease, and radiation-induced enteropathy. Finally, we discuss the beneficial role of eosinophils, which contribute to the resolution of pathogenic conditions and to the modulation of homeostatic biologic responses.

Acetaminophen (APAP) known as paracetamol is the main ingredient in Tylenol, which has analgesic and anti-pyretic properties. Inappropriate use of APAP causes major morbidity and mortality secondary to hepatic failure. Overdose of APAP depletes the hepatic glutathione (GSH) rapidly, and the metabolic intermediate leads to hepatocellular death. This article reviews the mechanisms of hepatotoxicity and provides an overview of current research studies. Pharmacokinetics including metabolism (activation and detoxification), subsequent transport (efflux)-facilitating excretion, and some other aspects related to toxicity are discussed. Nuclear factor erythroid 2-related factor 2 (Nrf2)-regulated gene battery plays a critical role in the multiple steps associated with the mitigation of APAP toxicity. The role of Nrf2 as a protective target is described, and potential natural products inhibiting APAP toxicity are outlined. This review provides an update on the mechanism of APAP toxicity and highlights the beneficial role of Nrf2 and specific natural products in hepatoprotection.
