Renewable energy sources play a key role in achieving carbon neutrality and zero net emissions in the power generation sector. Various efforts have been made to support the deployment of renewable energy, particularly solar photovoltaic and wind power, including policies to internalize the external cost of carbon emissions. In this study, we conducted a financial analysis of a 800 MW floating photovoltaic system and compared it with ground solar power generation. Additionally, we conducted a cost-benefit analysis that included the social cost of carbon. The findings showed that the floating photovoltaic project can meet the profitability target through an appropriately designed internalization of the social cost of carbon.

This study suggests a model for calculating total benefit rigorously to use the contingent valuation method (CVM) in cost-benefit analysis (CBA). Estimating households' willingness to pay through survey method, the study attempts to demonstrate if a respondent's income and the distance between a respondent's residence and the location of a target facility affect her willingness to pay. The estimation results from a structural model show that income and distance-decay effects exist and that the calculated total benefit varies largely when these effects are ignored. The study emphasizes the effects of income and distance-decay on the total benefit must be carefully considered in using CVM for CBA. Even though the total project cost is precisely estimated, the benefit/cost (B/C) ratio may differ largely when the total benefit is not correctly calculated. Also, an ad hoc model generates significantly different estimates from the utility difference model this study adopted. The difference in estimates suggests that the total benefit has to be estimated by a structural model. Finally, simulations are performed to check the validity of the model as well as to predict consequences when income and distance-decay effects are not properly treated. The results from simulations reveal it is not desirable to ignore those effects considering the perspectives of balanced regional development.

We are faced with the crisis of the R&D investment because of the effects of the IMF conditions. Most of the laboratories are going to restructure by the cutting off of money, man power and the reduction of R&D theme. Therefore it is necessary to allocate the R&D resources effectively to R&D projects. The evaluation and the selection of R&D projects have been recognized as the most important process for the allocation of the R&D resources. The result of the KITA(1997) shows that the commercial success rate of the R&D from new-product brain storming is only 5.8%. This study aims to analyze the actual conditions of the cost benefit analysis(CBA) of R&D projects of selected laboratories and to study measure methods of the R&D benefits. The research method of this study reviews the CBA of R&D firstly, and surveys 200 selected high ranking labs of R＆D expenditures. For the comparison of the results between '87 and '97, this survey used the same questionary for each year. As the result of the survey only 27 labs(response rate 13.5%) responded. The result of the '97 survey is as follows : The CBA is used by 44% of responding labs. The economic evaluation method for the R&D project selection is used by 48% of labs and this numbers increased by over 10 percents points compared with the result of '87. The CBA is used for about 40% about each of the budget preparing and the budget analysis, and by 30% of labs to analyze sales and expenditures of the overall period of the project. As the measurement of benefits of R&D projects, 30% of labs responded that it is impossible to measure the benefits, and 20% of labs measured the benefits between sales and expenditures of R&D projects.

This study begins with emphasis on the approach to public policy development and the extent to which a GIS framework can be used to evaluate projects objectively. This paper relates to public policy making and the use of GIS as a strategic management tool rather than the development of GIS technologies which has been the focus of attention since the advent of the first generation GIS systems in the 1960s. In order to consolidate a view towards public policy, the aim of this study is to show the advantages of using GIS to generate results which could be evaluated by cost and benefit analysis giving options of the alternative methods to estimate the feasibility of projects (both tangible and intangible) in a real public policy scenario. This study also reports that the tangible benefits associated with the GIS projects are better information processing, the easy analysis of data and the cost savings of map updates and printing, whilst the intangible benefits include quality decision making, and precise management of data through computing networks. In GIS context, the task of analysing and evaluating GIS projects is assumed in order to facilitate scientific and quantitative cost-benefit analysis. Previous methods of the cost-benefit analysis has not fully supported the evaluation of the intangible benefits and it has not been possible to make public policy realistic or scientifically understandable limiting decision makers in public domain. With the GIS decision makers are able to explore the potential of projects with this powerful decision supporting tool in practical application. On the basis of its potentials and limitations to cost-benefit analysis, therefore, it can be concluded that more flexible analysis and evaluation methodologies are needed to extend into the intangible benefits. In order to balance the evaluation of both quantitative and qualitative approaches on the cost-benefit analysis new or additional utilities will be required for the next GIS generation appraisal tool.

Capstone design course has been opened in order to improve students' practical project in undergraduate courses. This paper presents the efficient operation method for capstone design course. The proposed capstone design is operated such as outside outsourcing institute of industry, that is, the industry suggests the topics and fourth grade students work on this project during this year, and third grade students take over same project and proceed to improve in next year, so it is the continuous operating. Based on this system, industry can get the desired project outputs, and the university can give practical team project experience for students, so a mutual benefit between the industry and university can be possible. The proposed operating system is actually applied to the department of computer engineering, the questionnaire surveys are performed to participated students and corporate mentors, and then the operating results of the proposed system are analyzed.

Although actual business environment is getting difficult and hard, IT companies tend to shy away from of annual investment. Many firms have already reached the 25 percent level. However, the profit and the result of their annual investment needs to be evaluated objectively. IT investment analysis usually proceeds by comparing benefits and costs of an IT investment. Much of the problem derives from the historical treatment of IT as an overhead expense rather than a capital asset. What is most worrying about the current situation is the pressure to take a very short-term view of IT. Therefore, this research aims to analyses and justify the necessity of Visionary IT Investment. For this, it is crucial to identify the factors, which affect positively Visionary IT Investment and understand the role of CIO and explain the result of Visionary IT Investment, which is differed to related business and by different business environment. As a result of this study, the legitimacy of IT Investment is proved through analyzing the business value of not investing and cost-avoidance strategies.

In 2019, the Seoul metropolitan government established its own 'Seoul-type paid sick leave project'. Although the central government had to introduce such a system, which is also called sickness benefits, it was not implemented. In order to understand the process by which the Seoul government has implemented such a policy, this study used Kingdon's multiple streams framework. As a result, in the problem stream, it was found that the economic burden of sickness has been considered only in terms of medical expenses in the past of Korea. Then Songpa's three women and Middle East respiratory syndrome incidents raised awareness of the necessity of the sickness benefit system in 2014 and 2015. In the political stream, several social affairs such as national health insurance huge surpluses and the 2017 presidential election opened policy window. At that time, Seoul Mayor actively promoted sickness benefits as a policy entrepreneur. In the policy stream, the sickness benefit system has gained new attention through political events. To summary, these three streams flowed separately and then they assembled around huge political affairs. As a result, it was confirmed that Kingdon's model is the most effective theory than any other models in analyzing the health care policy decision process in Korea.

Managed Aquifer Recharge (MAR) in the form of Aquifer Storage and Recovery (ASR) systems are being applied for numerous water augmentation projects both in developed and developing countries. Given the onset of Climate Change and its influence on weather patterns and land use, it has been acknowledged the utilization of this technology will be ever increasing. This technique like all others does have its drawbacks or disadvantages, whereby to overcome these drawbacks or disadvantages it is recommended that logical planning process be followed. In this study, we developed a decision framework known as "Decision framework for the planning, designing, construction/testing and implementation of subsurface water storage system" to further standardize the planning and design process of subsurface water storage system to increase the probability of having a successful ASR/ASTR project. The formulation of this framework was based on earlier frameworks, guidelines, published papers and technical reports which were compiled into a data collection database. The database of which consider both qualitative and quantitative aspect for example recharge objectives, site location, water chemistry of the native, source and recovered water, aquifer characteristics(hydraulic conductivity, transmissivity, porosity), injection/pumping rate, ecological constraints, societal restrictions, regulatory restrictions etc. The assimilation of these factors into a singular framework will benefit the broad spectrum of stakeholder as it maps the chronological order under which ASR project should be undertaken highlighting at each stage the feasibility of the project. The final stage of which should result in fully operational ASR system. The framework was applied to two case studies and through the application of a modified ASR site selection suitability index (Brown et al., 2005) a score was derived to identify the performance of each site. A high score of which meant a maximize chance of success given the reduce presence of project constraints.

This paper discusses issues faced by individual building industry clients. These form the majority of clients but, because they do not possess high purchasing power, they attract less attention in the industry. Given that key decisions on project definition and procurement strategy are made at the pre-project stage, the industry would benefit from knowing relevant aspects of its clients' attitudes and behaviors, so that it can support them. There is a lack of research on this subject, and so we first describe a theoretical framework and research methodology that were developed for this specific group of clients. Theory adopted from consumer behavioral research was introduced to develop a general behavioral model of individual clients. In this model, individual clients are assumed to seek and then process information after acknowledging normative activities. To validate our model, a field survey was conducted using randomly selected individual clients. Their opinions on the importance and difficulty of 12 normative activities were analysed to establish a general attitude. Information seeking behaviour was investigated by measuring the frequency and type of source that they contacted to conduct the normative activities. The attitudes and information seeking behaviour presented in this research will contribute to the development of project tools for supporting these clients.

This study evaluates the economic benefit of the project constructing the international riding arena having been built at Sangju in Gyeongsangbuk-Do by the willingness to pay (WTP) of residents in the province. As the evaluation method, the dichotomous choice contingent valuation method (CVM) is adopted with the additional questions of whether his/her WTP is zero, to improve the statistical accuracy of evaluation results. Considering the arena's administrative location, the population of the surveys for analysis is confined to residents of Daegu and Gyeongsangbuk-do. The survey is conducted through personal interviews. It turns out that the WTP per household per year is evaluated as 1,847 won and the total yearly benefit of the Sangju international horse riding arena is estimated as 3.56 billion won.
