Public private partnership (PPP) procurement was introduced into Singapore in 2003, and 10 PPP projects was successfully completed and have been in operation. The objective of this study is to identify the critical risk factors and risk allocation preferences for PPP projects in Singapore. To achieve this objective, a comprehensive literature review was carried out and 42 risks were identified and grouped into three meta levels, i.e. macro, meso and micro levels. The questionnaire survey produced 48 completed questionnaires from 48 different contractors. The survey results indicated that 23 risk factors had significantly high criticalities and that four macro-level risks, four meso-level risks and two micro-level risks were among the top 10 risk ranking. "Lack of support from government", "availability of finance" and "construction time delay" were perceived as the top three critical risks. Also, the result implied that micro-level risks had a higher criticality mean score than macro-level and meso-level risks. The findings of this study help both public and private sectors to better understand the risks and their allocation in PPP projects, providing valuable information for organizations that intend to participate in PPP projects in Singapore.

An emphasis on public-private partnership (PPP) in the regulatory policy process can overcome the challenges hindering regulatory effectiveness with the emergence of fast developing technologies and new industries. This study attempts to evaluate quantitatively different aspects of institutional settings of South Korean regulatory policy in terms of stakeholder engagement as PPP, using evidence-based data released by the OECD. From the results of the principal component analysis, South Korea can be evaluated as being at a very good level overall in its institutional establishment. Nevertheless, the fact that the outcome of regulatory reforms in South Korea is still insufficient compared with this well-established system suggests that the country should concentrate on improving system operation. Consequently, this study makes policy suggestions to improve regulatory effectiveness through PPP by supplementing the facets that are well-equipped but not feasible with respect to regulatory policy cycle, regulatory governance, regulatory method, and conflict resolution.

The suggestions that follow are about the plan for the cooperation between private security and local government and the enhancement of its service for facing the change of public peace environment. Fist, by a local government collecting funds, the business for revitalization of local economics should be done to enhance local economic independence. Second, the autonomous right of a local government should be reinforced and the center for taking complete charge of local security should be established in the self-governing body. Third, the private security should be connected with the local characteristics, the role of which enlarged as well. For this developing the model of security service for the local area and working together between private security and police should be achieved. Fourth, it is necessary for a local government to entrust the private security with its public security service. For this it should be achieved to set up the range of local security service and inform local residents of the advantage of security service entrusted to private security. Finally, in connection with the new system of local police, it is necessary to have clear grasp of the work related to the private security among local police services and private security business and local police should take partial charge of the public peace service. Through the cooperation between private security and local government, the role of private security will be enlarged and its business revitalized as well.

This study aims to examine the effect of Operating Costs and Income, Loan to Deposit Ratio on the Return on Asset (ROA) of Public-Private Foreign Exchange Banks listed on the Indonesia Stock Exchange (IDX) during the 2015-2018 period. This study is a quantitative study using financial reports of Public-Private Foreign Exchange Banks listed on the IDX as a data source. This study's population is 25 Public-Private Foreign Exchange Banks listed on the IDX. This study uses purposive sampling to determine the sample to produce 21 banking companies. Data was analyzed using multiple linear regression methods and descriptive statistics. The F Test calculation results state that all the variables of free operating expenses, operating income, and the loan to deposit ratio simultaneously and significantly affect the return on assets (ROA) variable in Public-Private Foreign Exchange Banks listed on the IDX. This study's results indicate that simultaneously Operational Costs, Operational Income, and Loan to Deposit Ratio have a significant effect on ROA. Operational Costs and Operational Income have a significant negative impact on Return on Assets. The third hypothesis shows that the Loan to Deposit Ratio has a positive and insignificant effect on Return on Assets.

Public-private partnerships (PPP) projects are becoming popular in both developed and developing countries due to their ability to access new financing sources and transfer certain project risks to the private sector. PPP has been an active research area where the concept of Critical Success Factors (CSF) is often discussed by researchers. This study aims to identify the CSFs for various PPP infrastructure projects that have been explored in previous CSF studies. This article reviewed the literature about CSF in PPP projects from the years 2002 to 2021, compared the findings of studies regarding the identified CSFs, and consolidated the CSFs that can be applied to various PPP infrastructure projects. The results showed that dominant research focused on general infrastructure, where CSFs can be applied to all infrastructure sectors rather than any specific sector. The most identified CSFs from the study are favorable and efficient legal frameworks, appropriate risk allocation and sharing, a robust and reliable private consortium, a competitive and transparent procurement process, and political support and stability. The findings from the study can provide an overview of CSFs that are relevant to specific PPP infrastructure sectors like building infrastructure, transportation, water, etc. as well as for general infrastructure. In addition, the results can also be used for further empirical analysis.

Students' questions are essential and important for learning, but previous research and experience of instructors shows that there is a lack of interaction between instructors and students in online classes. This research studies how learners can effectively ask questions in online classes at engineering colleges. Based on two axes of anonymity and openness, the four different types of questioning methods were suggested as 'onymous/public', 'onymous/private', 'anonymous/public' and 'anonymous/private.' In this study, seven communication channels were applied to check their effectiveness in an online class. The results showed that learners' satisfaction with learning outcomes increased compared to previous offline classes, while satisfaction with teaching methods was similar. Additionally, among the four types of questioning methods, the preference and effectiveness of 'anonymous/public' was highest, followed by 'onymous/private'. This study suggests several implications of educational approaches to online education in engineering colleges.

The purpose of this study was to examine the factors influencing the attitude toward the increasing role of private health insurance(PHI). In the Korea Welfare Panel Data 2007, a sample of 1,675 (adjusted by weight value: 1,607) respondents on an opinion on promoting PHI was used in the study. With independent variables including socio-demographic characteristics, health status, health-related behavior, and opinions on welfare service, ordered-probit model was used to analyze the attitude toward PHI. Negative opinion on the increasing role of PHI were responded by 54.6%(n=877) of the respondents, whereas 22.2%(n=373) were positive and 23.2%(n=357) were neutral. Old people, the better off, those with worse self-assessed health status, and those having an experience of health examination tend to have the positive attitude toward the increasing role of PHI. Women, those with chronic diseases or disorders and those who do not agree that comprehensive welfare benefits reduce work incentive showed negative attitude toward PHI. When comparing the needs for PHI before and after medical utilization, ex-ante need tends to strengthen the tendency to support private health insurance. This study will contribute to the discussion on the optimal mix of public and private health insurance in Korea by a better recognition of attitude toward PHI and health care system.

Because the public security order needs the compelling power to maintenance the peace and this power is exercising only by police. They don't have the trust about the role of the private security as the crime prevention institution. But, they consider the private security is just for anyone in particular and special class by their demand. And also, they consider the private security is very expensive to utilize for their security in the everyday life. There for, some people have trust for the private security and if they have a chance for the security, they consider to utilize the private security for their safe life as an security agency.
