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.

Neutrophils are innate immune cells that constitute the first line of defense against invading pathogens. Due to this characteristic, they are exposed to diverse immunological environments wherein sources for nutrients are often limited. Recent advances in the field of immunometabolism revealed that neutrophils utilize diverse metabolic pathways in response to immunological challenges. In particular, neutrophils adopt specific metabolic pathways for modulating their effector functions in contrast to other immune cells, which undergo metabolic reprogramming to ensure differentiation into distinct cell subtypes. Therefore, neutrophils utilize different metabolic pathways not only to fulfill their energy requirements, but also to support specialized effector functions, such as neutrophil extracellular trap formation, ROS generation, chemotaxis, and degranulation. In this review, we discuss the basic metabolic pathways used by neutrophils and how these metabolic alterations play a critical role in their effector functions.

The purpose of this study is to analyze the mediating effect of career decision-making self-efficacy on the relation between the social support of professors and the career preparation behaviors of students who specialize in foodservice & culinary art. The participants of the study consisted of 250 students from the departments related to foodservice and culinary art of the three universities located in Chungcheong province. A total of 217 responses out of the 250 questionnaire were analyzed without the 33 incomplete questionnaires. The results of this study are as follows. First, it was shown that professors' social support had a significant positive effect on the career decision-making self-efficacy and the career preparation behaviors. Second, it shows that the career decision-making self-efficacy played a partial mediating role when the social support of the professors is related to the career preparation behavior. Therefore, the career education based on emotional, informational, material, and appraisal supports of the professors probably play a critical role in improving the career decision-making self-efficacy and the career preparation behaviors of the students majoring in food service & culinary art.
This paper considers logistics decision support system which deals with transportation mode selection considering transportation and carbon emission cost. Transportation and carbon emission costs vary with the choice of transportation modes and to become competitive companies need to find proper transportation modes for their logistics services. However, due to the restricted capacity of transportation modes, it is difficult to balance transportation and carbon emission costs when designing logistics network including transportation mode choice for each service. Therefore this paper aims to analyze the trade-off relationship between transportation and carbon emission cost in mode selection of intermodal transportation and to provide optimal green logistics strategy. In this paper, the logistics decision support system is designed based on mixed integer programming model. To understand the trade-off relationship of transportation and carbon emission cost, the system is tested with various scenarios including transportation of containers between Seoul and Busan. The analysis results show that, even though sea transportation combined with trucking is competitive in carbon emission per unit distance travelled, the total cost of carbon emission and transportation for the sea transportation may not have competitive advantage over other transportation modes including rail and truck transportation modes. The sea-based intermodal logistics service may induce detours which have negative impacts on the overall carbon emission. The proposed logistics decision support system is expected to play key role in green logistics and supply chain management.
Startups play an important role in economic growth and job creation in niche markets, thus governments regularly expand their research and development(R&D) budgets accordingly. As stratups are more dependent on governments to compensate for insufficient resources and capabilities than large and medium-sized companies, trust in government policies will be important. In this study, we analyzed the impact of startups' trust in government R&D policies on innovation performance. There were three major results. The first result is that government R&D investments in startups increase innovation performance in the manufacturing and high-technology industries but did not affect other industries. The second result is that trust in government R&D policies increased innovation in high-and medium-high technology and manufacturing industries. The third result is that trust in government R&D policies affects innovation before, during, and after evaluation of support process. We analyzed the importance of trust to the effectiveness of government R&D support to determine how to effectively provide it. The results show that governments need to differentiate the types of R&D support they provide according to the target firm's technology level and whether they are a manufacturing company and that appropriate R&D support mechanism should be developed for low-technology and non-manufacturing companies. Finally, governments should allocate resources and make fair and transparent decisions to help companies grow, not to better supervise them.
The government is focusing its attention and support on start-ups. Nevertheless, there is anxiety and fear about starting a business at the base of public awareness. Experienced as a way to overcome fear and difficulty. Few prior studies have been done on experience factors as ones influencing entrepreneurial intention. In this study, I studied whether the experience of successful entrepreneurship through cultural indirect experience affect the resolution of fear about establishing a business. Among the influencing factors on the entrepreneurial intention, business motivation, social support and awareness of entrepreneur were selected as independent variables. In addition, by applying the cultivation theory, the drama role models were set as a controlling variable. For empirical analysis, a survey was conducted targeting 399 ordinary persons. The hypothesis was tested through regression analysis using the SPSS 23 statistical package. The moderating effect was analyzed using Process Macro 3.5. Self-fulfillment, livelihood, economic motivation, social support, and awareness of entrepreneur are sub-factors of business motivation, And all of these had a positive significant effect on entrepreneurial intention. Among the significant variables, self-fulfillment was found to have the greatest effect. On the other hand, as a result of analyzing the moderating effect of the drama role model, it was found play a role in controlling between self-fulfillment and entrepreneurial intention, between livelihood and entrepreneurial intention, and between awareness of entrepreneur and entrepreneurial intention. Based on these research results, academic and practical implications were presented.
Diverse official policies in community are available for caregivers to take care of the elderly in the US and the UK. This study aims to examine the recent changes in government supports based on The Recognize, Assist, Include Support and Engage (RAISE) in the US, and those by Carer Act 2014 in the UK, to take any good lessons for Korean policy. Caregivers will play a new role to develop innovative treatment for patient-centered care. The UK strengthens to provide various efforts for working carers while assuring economic efficiency in labor market with empirical evidence. The major four ways to support carers were developed agreed with the acknowledge of caregiving value and their human right; financial support, direct services for carers, flexible work time, and advocacy. Korean supports policies for carers in long-term care and social welfare will be more effective in community care system if more evidence based policies are prepared.

Recently, various studies on the entrepreneurial ecosystem have been conducted. The entrepreneurial ecosystem is composed of various elements such as entrepreneurs, governments, and infrastructure, and these factors interact to contribute to economic development. The purpose of this study was to analyze differences in importance and performance of the entrepreneurial ecosystem for startups using the importance-performance analysis (IPA) method. Based on this, the importance and current level of the components of the entrepreneurial ecosystem were identified and policy implications were presented. The results of the study are as follows. The importance ranking was in the order of startup support program(4.43), startup funding (4.39), market accessibility(4.30). The ranking of performance was startup support program(3.81), ease of starting a business(3.76), support for startup support institutions(3.66), and startup funding(3.66). All elements of the entrepreneurial ecosystem showed higher importance than performance. This means that the components of the entrepreneurial ecosystem in Korea are recognized as important, but do not play a significant role in terms of performance for startups. In addition, the factors with the highest improvement in the importance-performance matrix were 「safety nets for startup failure」, 「culture of acceptance of failure」, 「ease of market entry」, 「ease of startup survival」, and 「ease of exit」. This study suggested improvement measures such as establishing a social safety net, improving awareness of startup failure culture, matching successful startups, strengthening scale-up support by growth stage, easing regulations in new business fields, and diversifying investment recovery strategies.

The purpose of this study is to examine the limitations of university operating system changes as a result of the policy changes and outcomes of the university lifelong education system support project by project period, and based on this, to propose a development plan to support the university's adult learning system. In this study, we sought to investigate changes in the higher education environment and changes in lifelong education in universities through analysis of literature and various data. The changing times of technological innovation and changes in knowledge require continuous learning even after school education, and the need for re-education and improved education is increasing. Therefore, the Ministry of Education and the National Institute for Lifelong Education have been actively carrying out support projects for lifelong learning-centered universities since 2008 to provide adult learners with opportunities to study. This project is centered around universities and the local community, and is promoting various types of changes in educational operation, such as reforming the university's academic system to be adult-friendly and operating night or weekend classes in order to provide educational opportunities for adult learners. Now, universities must play a role as a hub of regional lifelong education for the coexistence of the region and university, and as a key institution responsible for the contemporary tasks of sustainable development and coexistence between the university and the community.
