Underground infrastructure systems provide essential public services and goods through buried structures including water and sewer, gas and petroleum, power and communication pipelines. The majority of existing underground infrastructure systems was installed in green field areas prior to development of complex urban built environments. Currently, there is a global trend to escalate major demand for underground infrastructure system renewal and new installation while minimizing disruption and maintaining functions of existing superstructures. Therefore, Engineers and utility owners are rigorously seeking technologies that minimize environmental, social, and economic impact during the renewal and installation process. Trenchless technologies have proven to be socially less disruptive, more environmentally friendly, energy conservative and economically viable alternative methods. All of those benefits are adequate to enhance overall sustainability. This paper describes effective sustainable solutions using trenchless technologies. Sustainability is assessed by a comparison between conventional open cut and trenchless technology methods. Sustainability analysis is based on a broad perspective combining the three main aspects of sustainability: economic; environmental; and social. Economic includes construction cost, benefit, and social cost analysis. Environmental includes emission estimation and environmental quality impact study. Social includes various social impacts on an urban area. This paper summarizes sustainable trenchless technology solutions and presents a sustainable construction method selection process in a proposed framework to be used in urban underground infrastructure capital improvement projects.

Carbon neutral policy in Korea pays limited attention to the concept of sustainable economic growth. This limitation can be compared with other countries' carbon neutral policies such as US, UK and China where the climate change policies are closely connected to economic policies to boost further economic growth. This paper adopts a Ramsey growth model to account for the impact of carbon neutral policy on long-term economic growth and the accumulation capital. The model incorporates the Hartwick rule to allow sustainability of economic growth by transforming resource input into other input factor for growth. The analysis provides a possibility of low accumulation of capital as a result of carbon neutral policy in the absence of effective transformation of fossil-fuel factor into growth-related productive capital. Such low capital stock can be more aggravated when there exists a rent-seeking behavior of various interest groups with voracity to exploit social capital.

Three years after establishment, companies are said to face a period of risk called the "valley of death." To start a venture company and make it sustainable, the chance of failure must be minimized. According to an in-depth assessment report on special taxation in 2015, the one-year survival rate of Korean companies was about 60 percent and the five-year survival rate about 30%. These rates are low compared to those of major OECD member countries. Worse, such rates in Korea are decreasing year by year. The purpose of this study is to classify the success factors behind venture companies into human capital, social capital and financial capital, and verify through empirical analysis the factors influencing the success of venture companies based on the mediating roles of capability of the startup team and that for innovation. To find the success factors behind venture companies, this study first examined the theories derived from previous studies. SPSS 21 was used as the study method, while descriptive statistics, exploratory factor analysis and CMB test were conducted. In addition, SmartPLS 2 was used for confirmatory factor analysis, hypothesis test, mediation effect. The results of this study can help efforts toward job creation and economic revitalization pursued by the creative economy policy of the incumbent Korean administration. They can also be used as the cornerstone for venture companies in their pursuit of success.

As quality of life improves recently, people began to pay more attention to outdoor environment and outdoor activities. In case of the U.S.A., community garden is utilized as space for plant cultivation and horticulture activities and the space is also used for complex activities such as education, play, leisure and rest. At the same time, such diverse activities are linked with creating social and economic wealth, thus creating sustainable values in the community. This study targets to identify the social and economic effects of community garden. For this purpose, the study analyzes the detailed cases of community gardens in the U.S. and analyzed the contents of the study based on the theory of social capital. In case of Korea, community gardens are operated in the form of urbane farming and parks in most cases but it is desirable in terms of contribution to the community and sustainability to manage the community gardens with space characteristics and programs that set up communities by gathering many residents in the community. It is necessary to approach the matter of community garden comprehensively and to set up comprehensive and complex plans to form community gardens. This study is expected to function as an important base for such purpose.

Purpose: To examine the strength of social capital (SC) that are likely to affect Created share value (CSV) factors. This research aims to conduct a literature review to establish the components of SC and CSV identified within educational research and use factor analysis to identify how numerical values differ from the average and the amount of variance expressed in eigenvalue and factor score. Research design, data and methodology: To achieve the purpose of the study and provide adequate empirical results, we conducted the structural equation analysis using IBM AMOS 24.0 and collect online questionnaires from top practitioners, managers and non-managerial employees in Korean education firms, which will be used to conduct a factor analysis to assess SC's effect on CSV. Results: Final analysis of the path coefficient of the research model indicated that the SC values based on six have a significantly positive (+) effect on CSV values based on three categories (β=.35, p<.001). Therefore, the current research accepts the hypothesis in determining that SC can enhance the impact of CSV in educational companies. Conclusions: From the study, the practitioners of education companies should make more efforts to find action plans to create corporate social responsibility and shared value, which are required throughout society.

The structural and sustainable implementation of the microfinance policy is required to be successful. To this end, the government should focus on availability and accessibility of the public microfinance, away from providing the beneficial financing (financial benefits)featured by the combination of the welfare and finance in the past. In addition, the government-sponsored microfinance needs to aim for performance-oriented evaluation that leads to stabilization of financial life of ordinary people or increase of income, moving away from conventional funding based on the scale and the quantity for the poor. It is necessary to implement the following policies in order for the Moon's administration to take the government-sponsored microfinance to the next level. The government-sponsored microfinance must be in the market failure domain, but nonetheless, it is required to be managed by structural and sustainable ways so that it complies with the market principles and does not crowd out the private microfinance. Last but not least, making the best use of the capital market function can be a way to fund social enterprises or social economy enterprises. This aims to enable catalyst capital in the capital market to play a prime role for the inflow of private capital for the purpose of creating the social value.

Researches recently made in advanced countries into entrepreneurship found that various resources and information are mainly provided to ventures through social capital, which is a resource capital based on a network, and through corporate entrepreneurship. This research is an exploratory study on the effects of social capital and corporate entrepreneurship of new ventures upon their corporate performance, conducted from the standpoint of dynamic capability. For that purpose, a questionnaire investigation was made of 171 venture entrepreneurs in Korea, and the following are the results of an empirical analysis of responses to the questionnaire. First, it was found that social capital, which is a resource capital based on a network, had a significant effect on corporate entrepreneurship. Second, social capital also had a significant effect on ventures corporate performance. Third, corporate entrepreneurship had a significant effect on corporate performance. These results imply that social capital and corporate entrepreneurship have a significant effect on the corporate performance of ventures, which have innate disadvantages concerning the supply of resources. On the other hand, ventures, which encounter relatively more intense demands for change and renovation, can be managed in a sustainable manner just when they adequately accumulate their social capital and utilize their external resources and appropriately conduct their corporate entrepreneurship activities.

This paper analyzes the impact of CSR on the capital market in Korea. Using listed firm data, we found that the creation of a sustainability report that indirectly measures the level of CSR can bring the stock rate of return difference of the capital markets representative market index. First, when a firm that publishes a sustainability report was compared in terms of its market rate of return, it showed a return increase of about 2%. We found that higher returns were gained through the competitive advantage of related business when the firm was actively involved in social responsibility. Second, subdivided by industry, firms belonging to the capital goods industry were found to reach a rate of return higher than that of industry. These firms were noticeable in that they were mainly industries that caused environmental pollution. Third, in an additional analysis, foreign investors were given the sustainability report of financial businesses, which was interpreted as a result of industrial properties. A sustainability report is a comprehensive report on the economic, environmental, and social activities of a firm. Firms must learn that they can gain trust through publishing trustworthy reports while achieving the lasting power of growth from the stakeholders.

Built-out issue of copper processing appearing recently in the Paldang watershed is a critical problem to deteriorate the basic framework of national water management policy as well as to be simply a copper-related problem. Up to now, Korea government has invested hard and relevant upstream areas have been victimized readily in a variety of field to comply its goal of 'Safe Water Supply'. Because of the reason, the desirable water quality level of the Paldang watershed has been maintained regardless of its dense population. Paldang drinking water management policy is based on residents' understanding which is considered as a 'social capital'. The issue raised in the aspect of water quality management policy should be reviewed on the basis of the 'social capital' concept. One regarding semiconductor industry as a potential industry to export many products in 10 years insists that the industry not be a simple private business but be a prominent part for national competitiveness. There is no doubt about this opinion. However, a nation should support environmental right-to-life of its people prior to any other tasks. In other words, it is really risky to give up people's right due to economic benefits. Therefore, it should not happen to trade 'life', the dignity of man, with national competitiveness which is likely to be preferred in these days. In addition, coherent policy not to destroy 'social capital' promoting Paldang drinking water resource management policy should be maintained.
