The study investigates the relationship and influence between religiosity, reward, and engagement in the public administration sector, both directly and causally via moderation. This study involved one hundred and twenty-three respondents in three local government organizations in Malang City, East Java Province, Indonesia, namely, the Malang City General Hospital, the Population and Civil Registry Office, and the Investment Office. The sampling method uses stratified random sampling from the total population of civil servants in Malang in the three institutions. The data analysis model of this study uses a quantitative approach with a unit of data analysis using the path analysis method. The analytical tools used are smart-PLS and SPSS. The results reveal that the direct combined effect of reward and religiosity has a positive and significant influence on the engagement. However, moderation between reward and commitment, which is bridged by religiosity, does not show positive and significant results. The non-positive relationship shown by testing moderation concludes that there is a separation of purpose between the portion of religiosity in the world of work, where religiosity in this study is only described as part of the concept of worship, and the relationship between the person and his God.

감사원은 각종 감사에서 증거자료로 공공부문의 정보시스템 데이터를 많이 활용하고는 있으나 데이터 자체의 신뢰성을 제대로 점검하지 못하고 있는 실정이다. 따라서 본 연구에서는 해외 선진 감사원의 감사사례를 분석하여 우리나라 공공부문의 데이터 신뢰성을 체계적으로 점검하는 기법을 개발하였다. 그리고 적용사례로 한국장애인고용공단에서 관리하고 있는 장애인고용부담금 데이터를 분석하여 점검기법의 적용가능성을 검증하였다.

In medical or public health research, it is common to encounter clustered or longitudinal count data that exhibit excess zeros. For example, health care utilization data often have a multi-modal distribution with excess zeroes as well as a multilevel structure where patients are nested within physicians and hospitals. To analyze this type of data, zero-inflated count models with mixed effects have been developed where a count response variable is assumed to be distributed as a mixture of a Poisson or negative binomial and a distribution with a point mass of zeros that include random effects. However, no study has considered a situation where data are also censored due to the finite nature of the observation period or follow-up. In this paper, we present a weighted version of zero-inflated Poisson model with random effects accounting for variable individual follow-up times. We suggested two different types of weight function. The performance of the proposed model is evaluated and compared to a standard zero-inflated mixed model through simulation studies. This approach is then applied to Medicaid data analysis.

Cloud storage provides an easy, cost-effective and reliable way of data management for users without the burden of local data storage and maintenance. Whereas, this new paradigm poses many challenges on integrity and privacy of users' data, since users losing grip on their data after outsourcing the data to the cloud server. In order to address these problems, recently, Worku et al. have proposed an efficient privacy-preserving public auditing scheme for cloud storage. However, in this paper, we point out the security flaw existing in the scheme. An adversary, who is on-line and active, is capable of modifying the outsourced data arbitrarily and avoiding the detection by exploiting the security flaw. To fix this security flaw, we further propose a secure and efficient privacy-preserving public auditing scheme, which makes up the security flaw of Worku et al.'s scheme while retaining all the features. Finally, we give a formal security proof and the performance analysis, they show the proposed scheme has much more advantages over the Worku et al.'s scheme.

This study was carried out to investigate the activities and job satisfaction of public health doctors in charge of community health programmes. Subjects were 138 public health doctors charged with community health project, registered in the roll of public health doctors, made out by Central Supporting Team for the District Health Work in 2002. Data was obtained from Ninety-six public health doctors. The response rate was 70%. The survey was conducted from March to April in 2003 bye-mail. The items of the questionnaire consisted of general characteristics of participants, understanding of their activities, support system, job satisfaction, and suggestions to improve the system. Collected data was analyzed using PC-SPSS 10.1. Descriptive analysis, t-test, and ANOVA test were used. The results are as follows: Most of the respondents showed a low participation rate in community health services, but they agreed to the importance of their activities and the necessity to modify and improve the system. 70% of the respondents were dissatisfied with their jobs. The participation in health planning and programmes of health center, and the degree of acceptance of their opinion from health center workers were significantly related to their job satisfaction. The participation rate of the public health doctors having specialty, in community health services is higher than that of the others. In terms of the supports for system operation, the reflection of one's intention in job arrangement process, education and public relation of this system, and the administrative and financial supports made significant differences in the job satisfaction and the accomplishment of their duty. The respondents hoped that the administrative and financial supports for public health doctors in charge of community health programmes should be reinforced to motivate them. They also wanted that they could keep from being overloaded with clinical services. They favored to conduct home visit, community diagnosis, health planning, and health promotion programs as their appropriate activities. From these results, we suggest some strategies to motivate and empower the public health doctors in charge of community health programmes.

Purpose: To identify the effects on tuberculosis mortality of a tuberculosis control program conducted at 108 community health centers in terms of structure and process. Methods: The dependent variable was tuberculosis mortality, and the independent variables were the structure(type of centers, staff, nurses, doctors, budget) and process(chest X-ray checking, immunization, case detection, health education, patients registering & managing) of the tuberculosis control programs at the community health centers. Data were analyzed using descriptive analysis and stepwise regression analysis. Result: Tuberculosis morality was positively correlated with type of centers(rural area)(p<0.01), but negatively correlated with type of centers(large cities) (p<0.01), (middle cities)(p<0.05), staff FTE(p<0.05), and number of nurses(p<0.05). Regression analysis indicated that type of centers(rural area)($\beta$=0.457) and case detection($\beta$=0.234) had a significant effect on tuberculosis mortality. Conclusion: Ultimately, this study will provide information to improve the effectiveness of tuberculosis control programs in community health centers.
