The purpose of this study was to analyze the level of the services provision of community health practitioners (CHP) and to find out the influence factors on the services provision of CHP. In this study the dependent variables were the level of community health services(CHS), maternal and child health services(MCH), family planning services(FPS), primary care services(PCS) and the ratios of preventive health services(PHS). And independent variables were predisposing, community demographic and task factors. For this analysis, atepwise regression was used. Data collected for the study on reorganization of health centers organization in 1985 was partly used. The findings of this study can be summarized as follows : First, total variance of independent variables for CHS, MCH, FPS, PCS and PHS are shown 62.5 percent, 58.3 percent, 41.8 percent, 17 percent and 61.9 percent respectively. Second, the most important variables which explain CHS, MCH, FPS, PCS and PHS was ratios of household contacted ($R^2$＝0.289), marital status ($R^2$＝0.177), marital status($R^2$＝0.167), ratios of household contacted($R^2$＝0.119) and management of preventive health services($R^2$＝=0.203) respectively. The independent varivbles used in this analysis presented that the explnining for the provision of preventive health service are more influenced than primary care services. In summary this analysis suggests that the level of preventive health services provision of CHP is low and the provision of primary care services compared with preventive health services are occurred independentely. In the future, the strategies for active preventive services by CHP must to be strengthened.

Objectives: This study was conducted to examine the immunization, knowledge, and preventive health behaviors for hepatitis A in college students. Methods: Structured questionnaire survey data were collected from a convenient sample of 266 students at two universities in urban areas. Data were analyzed with Pearson correlation coefficient, t-test, ANOVA, and multiple logistic regression analysis. Results: Only 10.5 percent of the students reported having had hepatitis A vaccination. The levels of knowledge and compliance of preventive health behavior were moderate with the mean scores of 15.56(${\pm}2.12$), and 26.78(${\pm}3.41$), respectively. A significant correlation was found between knowledge and preventive health behaviors. The compliance to preventive health behaviors differed by education on hepatitis A in the past. Conclusions: Vaccination rate of hepatitis A found to be low and the knowledge and health behaviors for hepatitis A prevention among university students are limited. Provision of vaccination, education and strategies to enhance preventive health behaviors are warranted to prevent hepatitis A.

Background : To propose effective strategies for successful implementation of QI in health care institutions, by identifying facilitating factors and barriers to conducting QI programs. Methods : In order to examine empirical evidence on the success factors or barriers to QI implementation in hospitals, a literature study was performed on the basis of MEDLINE search. Among the identified literature. 13 provided reliable findings and basis comprehensive discussion on this issue and thus were selected for in-depth analysis. A mailed questionnaire survey was conducted for hospital CEOs and QI directors of hospitals with 400 beds or greater to investigate what attributes of their organizations they perceived as success factors or obstacles to QI implementation. Result : The analysis of selected literature and survey results presented that the primary factors considered to be most important as successful implementation of QI were: strong support from hospital CEOs, setting higher priority for QI activities, continuous and persistent efforts in QI activities, and active participation of clinical staffs. The barriers identified in this study were : the lack of orientation and understanding of QI concepts, low level of interest and participation of physician in QI programs, the lack of evaluation and rewarding system for QI activities. Conclusion : By identifying factors that affect facilitation of QI, the study results will be of great use for either institutions being in the early stage of evolving QI or those looking for better strategies to achieve more active and persistent QI implementation in their institutions.

Purpose: The aim of this study was to identify the influence of knowledge, attitude and preventive health behavior of cancer on nicotine dependency in male college students who have a habit of smoking. Methods: In this study, a cross-sectional survey design was adopted for the 254 male college students who smoke in D and S city. The data was analyzed for descriptive statistics, t-test, Pearson's correlation coefficient and multiple regression analysis using the SPSS 20.0 program. Results: Knowledge about lung cancer (${\beta}=-.407$, p<.001), preventive health behaviors about cancer (${\beta}=-.223$, p<.001) and the smoking period ($5years{\leq}$) (${\beta}=.198$, p=.001) were identified as the factors influencing nicotine dependency of the subjects. The model explained 33% of variance in nicotine dependency (F=20.49, p<.001). Conclusion: The results suggest that anti-smoking educators should include the strategies to increase knowledge about lung cancer and preventive health behaviors of cancer, and to reduce the smoking period in their smoking cessation program.

Predicting remaining useful life (RUL) becomes significant to implement prognostics and health management of industrial systems. The relevant studies have contributed to creating RUL prediction models and validating their acceptable performance; however, they are confined to drive reasonable preventive maintenance strategies derived from and connected with such predictive models. This paper proposes a data-driven preventive maintenance method that predicts RUL of industrial systems and determines the optimal replacement time intervals to lead to cost minimization in preventive maintenance. The proposed method comprises: (1) generating RUL prediction models through learning historical process data by using machine learning techniques including random forest and extreme gradient boosting, and (2) applying the system failure time derived from the RUL prediction models to the Weibull distribution-based minimum-repair block replacement model for finding the cost-optimal block replacement time. The paper includes a case study to demonstrate the feasibility of the proposed method using an open dataset, wherein sensor data are generated and recorded from turbofan engine systems.

In the aftermath of the COVID-19 pandemic, the importance of collective efforts in promoting health preventive behaviors is accentuated, bringing sociopolitical factors into focus. To fully capture psychological drivers of health preventive behaviors in risk situations, anchored on the Model of Risk Information Seeking and Processing (RISP; Griffin, Dunwoody, and Neuwirth 1999), in retrospect of the recent COVID-19 pandemic, we explored whether and how individuals' vaccination behaviors are predicted by RISP-related variables (information insufficiency, affective responses, perceived information gathering capacity, subjective norms) and one's political identity. Findings from a survey of 705 adult participants in the U.S. showed that the effects of one's risk information insufficiency on his or her information seeking and affective response regarding the pandemic, which is also related to their risk susceptibility perceptions. More importantly, the impact of political identity on one's perceived risk susceptibility, and its association with vaccination behaviors are also identified. The findings of this study provide valuable insights for the development of effective health communication strategies for preventive health behaviors.

Purpose:The present qualitative study explored adolescents' perceptions regarding effective strategies to prevent adolescents from using tobacco products (TP). Apart from the commercial TPs, there has been emerging use of alternatives such as vapes, e-cigarettes and shisha. This unfortunate phenomenon continues despite the currently available preventive strategies. Thus, understanding of the perceptions of the current generation would be valuable to provide new insights. Methods: Purposive sampling was utilized to recruit 40 adolescents between the age of 15 and 16 years old attending public daily secondary schools. Eight focus group discussions were conducted among the TP users, ex-users and non-users. Data were analyzed using a thematic content analysis procedure with NVivo. Results: Among barriers with the currently available strategies were having teachers who smoke tobacco, addiction to nicotine and self-perceptions of being healthy. The content of any program should include knowledge on negative outcomes of using tobacco products and awareness of the legislation together with ways to overcome peer and family influence including improving self-efficacy and refusal skills. Strategies were suggested to be delivered using information technology which provides interactive learning and visual effects. Conclusions: Adolescents agreed that the content and delivery of tobacco use prevention strategies need to be revised to suit the current generation to ensure sustainability.
