Time and cost of construction are key factors in decision-making during a tunnel project's planning and design phase. Estimations of time and cost of tunnel construction projects are subject to significant uncertainties caused by uncertain geotechnical and geological conditions. The Gaussian Process Regression (GPR) technique for predicting ground condition and construction time and cost of mountain tunnel projects is used in this work. The GPR model is trained with data from past mountain tunnel projects. The model is applied to a case study in which the predicted time and cost of tunnel construction using the GPR model are compared with the actual construction time and cost for model validation and reducing the uncertainty for the future projects. In addition, the results obtained from the GPR have been compared with to other models of artificial neural network (ANN) and support vector regression (SVR) that the GPR model provides more accurate results.

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.

The maintenance of educational facilities is divided into inspection and management of facility managers residing in the school and Educational Environment Improvement Projects(EEIP) to carry out maintenance work. Educational support organizations collect maintenance requests through facility inspections by school-specific facility managers, and carry out numerous maintenance projects during the year. The EEIP has the characteristic of Program Management with interrelationships between projects, not multiple projects management. The purpose of the EEIP is to eliminate the inconvenience of school facility users and increase their satisfaction, and achieving the goal is judged to be successful. Despite the importance of management and performance measurement utilizing Critical Success Factor(CSF) for the operation of successful educational facility maintenance management programs, the system for achieving the goals is insufficient. This study derives CSFs for each stage of the EEIP for the success of the EEIP. The CSFs for each stage of the EEIP is expected to serve as a basis for evaluation of educational facility maintenance management programs and can be used as an evaluation index in the future.

Objectives : The 3rd community health plan let health centers select and promote core projects considering budget and manpower. This study analyzed the content and selection processes of core projects, using the nationwide 3rd community health plans, to give relevant information on health center policies. Methods : Classification criteria for content analysis of core projects were established and verified through a literature review and by specialist discussions. Fifty plans were selected by stratified proportional random sampling for regional characteristics. And coding criteria standardized through coding repetition and discussion, by 2 persons (k>0.7). Using stratified proportional random sampling for 16 cities and provinces, regional characteristics, 117 plans were selected, and the contents of the core project selection processes and program contents analyzed. Results : The survey was used by 59.8 % of samples as a core project decision-making method. The partici- pants included 98.6, 81.4, 40 and 38.6% of the health staffs, residents, medical institutions, and administrators, respectively. Discussion was used by 15.4% of samples. The participants were health staffs by 100% as a great. The ranking of the frequencies of the selected core projects were, in order; chronic disease control, health promotion, elderly health, maternal-child health, and oral health at 16.4, 14.8, 14.3, 12.7 and 11.9%, respectively. Analyses on the chronic disease control and elderly health contents showed the diversity of object disease, high rates of visitors on patient detection programs, high rates of unclear target populations, and the provision of medical exams and treatments as the main services, with high variations in business per-formance. The national health budgets for health centers in 2003 were about 910 and 240 million won for chronic disease control and elderly health, respectively, which were less than for the other five priority core projects. Conclusions : The chronic disease control and elderly health at the health centers were not standardized for object disease, patient detection program, target population, service provision, and national support budget was insufficient. Thus it is necessary to develop standard guidelines, and increase financial support, for chronic disease control and elderly health

Although construction of any new nuclear power projects had not been launched since mid-1970s until recently in the USA, many new nuclear power plants have been constructed in many countries with the support of their governments mainly as part of their national energy security and electric source diversification policies. For many reasons, the nuclear power industry seemed to reclaim their renaissance from the beginning of this century and the investment in the nuclear power projects draw positive concern from the private financial sector. But the global financial crisis in 2008 and subsequent economic slow-down together with tighter bank credit regulations caused commercial banks, the main source of financing, to lose appetite for investing in new nuclear power projects. But the nuclear power economics shows that the nuclear power is viable in terms of the environmental benefit and long-term average cost compared to other power generation sources. Also doubt about nuclear power safety was much mitigated due to technology development and reinforced safety-related tests and monitoring. Therefore, the prospect for nuclear power market expansion remains positive although there are comparatively big differences among different scenarios. After Korea Electric Power Corp. won the UAE nuclear power project in December of 2009, the competition in nuclear power markets is undergoing huge changes. Competitors backed by the support of their own governments are now entering the market with many aggressive and innovative financing packages to win bids of new nuclear power projects. This report analyzed the nuclear power market prospects, competitive edges of nuclear power, risk management measures, and financing challenges and recommends alternative solutions to promote competitive edges in winning bids of new nuclear power projects.

This study draws implications by surveying and analyzing performance evaluation cases in Korea and overseas, and analyzes qualitative and quantitative performance evaluation indexes and evaluation models that fit the national R & D performance evaluation system through analysis of patent creation performance data or company status data. Also, in order to apply this to a specific group of companies with excellent exports and technical skills, we will conduct a case study on the performance analysis of patent strategy support projects based on the results of the survey. Although this study has some limitations in developing performance evaluation indicators due to the limited scope of business or business characteristics of the patent strategy support project, the qualitative evaluation system can be reviewed through previous studies and domestic and overseas case studies. Due to the problem of accessing and collecting data related to the performance of the support project, there is a limitation that performance analysis cannot be performed at a sufficient level. Nevertheless, after the completion of R&D support projects and patent strategy support projects, follow-up performance analysis can be performed through follow-up surveys. It is expected to be possible.

Currently, the Ministry of Strategy and Finance operates performance evaluation of the IT projects of the central government. Recently, with the advent of the Digital New Deal and the Digital Platform Government, the budget for IT projects has significantly increased, leading to a higher level of interest in their performance. In this study, performance-related characteristics were selected through previous research, and an empirical analysis was conducted to examine whether there are actual differences in the performance of IT projects given respective characteristics. As a result of the analysis, new projects and others performed by departments or offices had a statistically significant positive effect on each final evaluation score. In contrast, IT support as well as fund-based projects had a statistically significant negative effect on each final evaluation score. This study suggests that when evaluating the performance of IT projects in the future, it is important to consider the unique characteristics of each project, as these may contribute to respective differences in performance.

Korean sixth industrialization policy is similar to that of Japanese such as goal of policy, setup and promotion method of specific policy projects as it benchmarked a Japanese case. First of all, the certification systems of both countries, the most representative policy, are very alike that the governments officially certificate management bodies, prepare the ground for continuous sixth industrialization, devide intermediate support organization into the central unit and regional unit, and have the function of support and control of sixth industrialization management bodies. Furthermore, both countries create fund for sixth industrialization as an investment support policy, and push forward with the phased support policy businesses such as individual support and connected support for management bodies. However, there are some differences between certification systems of both countries such as process-oriented or result-oriented for certification, subtle differences of the role in support organization, and the range and rate of support.

Purpose - In order for actively pursuing medium and long term policies of Gangwon region to be effectively and efficiently driven, efficacious and practical development strategies are needed. In terms of regional revitalization in most regions that are dependent on the primary industry like Gangwon-do Province, the maintaining of local community becomes difficult and there are limitations on the support from the central government and local governments. Therefore, local communities need to implement measures not only to be financially independent but also maintain and activate themselves. And community business can be adopted to be a proper strategy to cope with this change. This study drew importance of a community business model appropriate for Gangwon-do region to figure out success factors. Research design, data, and methodology - This study aimed to come up with importance of community business model for Gangwon-do region by using AHP Method. AHP Method, which was developed by Professor Saaty in 1970', is a methodology to simplify complex problems for a rational decision making. A survey targeting related public officials and expert group was carried out and a total of 30 questionnaires were collected for the analysis. Results - Analysis model used in this study was to prioritize community business models of Gangwon-do region. The second hierarchy was divided according to local restoration type, local resource utilization type, environment improvement type, and life support type. The third hierarchy consisted of 5 items such as network, the middle structure, program, government support, and human resources to measure each importance. As a result, in the second hierarchy, local resource utilization type had the highest importance. In the third hierarchy, the middle structure had the highest importance, followed by government support, program, network, and human resources. Collectively, the results suggested that important critical factors of community business model of Gangwon-do region was the importance of local resource utilization model and the middle structure. Conclusions - Not only should projects that are already operating in the region but next community business projects that are planning in the Gangwon-do region should be practically operated in view of the importance and the models derived from this study.
