This paper examines the impact of ESG activities of domestic shipping companies on the cost of debt. It is known that companies with large information asymmetry tend to have high costs of debt. Corporate ESG activities have been identified as an effective means of reducing information asymmetry. By actively engaging in ESG activities, companies can lower the cost of debt by reducing information asymmetry. Therefore, this study aims to investigate whether these mechanisms, which have been observed in previous studies, also apply to domestic shipping companies. Multiple regression analysis is conducted on KOSP I-listed shipping companies from2010 to 2022. The cost of debt is set as the dependent variable, while the ESG rating is used as the explanatory variable. The analysis reveals that companies with a high level of ESG activities generally have a lower cost of debt. However, it is important to note that ESG activities of shipping companies do not seem to have a significant impact on their cost of debt. In fact, the level of ESG activities among domestic shipping companies is not particularly high (Hong, 2024). Despite these findings, domestic shipping companies should still strive for sustainable management to adapt to the rapidly changing business environment and meet the demands of the modern era. ESG management is a representative method for achieving sustainability. Therefore, shipping companies should not only focus on reducing the cost of debt but also on opening up the closed industry culture and communicating with capital market participants for sustainable growth. It is crucial for these companies to listen to the voices of stakeholders and embrace a holistic approach to sustainability.

The purpose of this study was to evaluate the usability and satisfaction of space to which positive elements in Leed-Certified Office Building are applied. The study was conducted using the three-step approach. The first step was to understand the building and identify the issues which included the analysis of floor plans, documentations, and the interview with designers and facility managers. The second step was FGI(Focus Group Interviews), which were conducted with mixed employees of rank and location of workplace. Finally, a web-based questionnaire survey was conducted on the 319 executives and employees. Methods of analysis used were quantitative analysis of questionnaire, qualitative analysis of open ended free-answer, and FGI in the second step. Satisfaction, preference, and comfort level were studied using cross tab, co-relation, ANOVA for quantitative analysis. The results of this study are as follows: First, lobby and atrium are representative elements that are functioning positively and it is recognized as sustainable spaces being utilized by users. Second, there are several dead spaces like green shaft, roof garden and sunken space although they can contribute to Leed-certification. Third, there are some problematic spaces such as the O.A. room and the urinals even though they contribute to the Leed-certification.

Sustainability became the keyword of our society worldwide, and it is undoubtful that buildings are mainly responsible for green house gas emission and energy consumption. Responding to current needs, US Green Building Council has launched the first LEED rating system in 1998. Since then, LEED has been evolved and it has multiple sub-system categorized by project types. This study aims to analyze characteristics of sustainable neighborhood development and to suggest methodology for establishing certification system in Korea. First, LEED-ND 2009(LEED for Neighborhood Development) was addressed with certified projects by US Green Building Council. After that, LEED-NC 2009(LEED for New Construction) was compared with green building certification criteria in Korea to find out unforeseen aspects by each system, in terms of sustainable neighborhood development. As a result of this study, sustainable neighborhood development requires a transition of architects' responsibility beyond building design. Building technology has been advanced at extremely fast pace, however, applying techniques to individual architecture would not make our town sustainable. This study provided basic resources to understand that creating sustainable neighborhood is social phenomenon and more studies should be undertaken to establish Green Neighborhood Certification Criteria in Korea.

Purpose: The purpose of the research is to find difficulty levels of LEED credits in each LEED level based on credits achievement in order to find important of LEED-HC credits to gain LEED-HC. Methods: The individual credits of LEED-HC v.2009 scorecards from USGBC website are analyzed. With achieved scores rate of LEED credits per each Level, all credits are reassembled in 4 different ranges (A~D); easy (A), easy-moderate (B), moderate-hard (C) and hard (D) to achieve scores. Results: 1) Achieved point rate in LEED-HC specific credits are low. These credits need to be reviewed carefully. 2) In 88 projects, 37 projects are gained Silver level which is more than projects in certification level. In order to encourage to gain LEED-HC level, Average Achieved rate to earn Certificate level needs to be risen. 3) Credits in range D rarely affect to gain platinum level. EAc1 (24 points) are critical to gain Silver and Gold level. However, EAc1 points are not effective to achieve Certificate level. Implications: This research will provide a fundamental back data to set up Korean Green building rating system for Healthcare.

The purpose of this study is to verify the factors affecting survival time by estimating survival rate and survival time using non-financial information of social enterprises using credit guarantee in credit guarantee institutions, and provide information to stakeholders to improve survival rate and employ to contribute to maintaining and expanding the As a research method, survival analysis was performed using a non-parametric analysis method, Kaplan-Meier Analysis. As a sample, 621 companies (577 normal companies, 44 insolvent companies) established between 2009 and 2018 were selected as the target companies. As a result of examining the factors affecting survival time by classifying social enterprise representative information and corporate information, representative credit rating, representative home ownership, credit transaction period, and corporate credit rating were derived as significant variables affecting survival time. In the future, financial institutions will be able to induce corporate soundness by reflecting factors that affect survival when examining loans for social enterprises, contributing to job retention and reduction of social costs. Supporting organizations such as the government and private organizations will be able to use it in various ways, such as policy establishment and education and training for the growth and sustainability of social enterprises. With this study as an opportunity, I hope that research will continue with more interest in the factors influencing social enterprise performance as well as corporate insolvency.

Recently, as the environment issue has been stand out, people's interests in energy consumption of the building have been increased as well. Especially, university has been classified as the one of the main causes of excessive energy consumption. Therefore, domestic and foreign universities are trying to build a green campus in an attempt for sustainable development. Since early 2000s, foreign universities have been aware that one of the main causes of global warming is an excessive consumption of energy in universities. Accordingly, they adopted various energy management programs for the conservation. Ultimately, enforcing energy conservation and using alternative energy resulted in lower expense and it was a great help for the universities. On the other hand, excessive consumption of energy in domestic universities has been considered as serious, which led them to become the second main energy consumers in 2010. However, it seems people do not truly recognize the impotance of energy management, therefore, relatively little attention has been paid to this matter. Based on Leadership in Energy & Environmental Design(LEED) rating systems for on-campus building operation and maintenance, this research suggests the evaluation standard to effectively analyze the energy management activity with the best practices conducted in foreign universities and to solve the problem of campus facilities management in domestic universities. The result shows that domestic universities do not have a designated task force for effective energy management and the lack of energy professionals hinders for the long term development. Therefore, domestic universities should recognize the seriousness of the excessive energy consumption and develop low carbon green campus through proactive management practices since this is very essential for domestic universities to get more competitive in this global era.

Environmental Impact Assessment (EIA) is an important policy implemented before starting development projects to estimate and reduce environmental impact. However, the difficulty of quantification on several rating categories has hampered comprehensive analysis. Instead of it, the current EIA just summarizes outcome of investigation. Therefore, EIA fails to definitively ascertain whether the development shold be approved or not. This study aimed at providing the way to comprehensive decision-making by applying Emergy analysis and Emergy indicators to EIA. Production (P), Emergy Yield Ratio (EYR), Environmental Loading Ratio (ELR) and Emergy Sustainability Index (ESI) were selected for indicators. The indicators of range approving the development were set up with comparing before and after development or according to circumstances of which view of average that was classified as region or industry is appropriate to analysis. As a result, the value after development of P should be higher than the value before development. EYR and ESI of the value before development should be higher than region or industry average. On the contrary to these, ELR of the value after development should be lower than region or industry average. To verify applying Emergy indicators to EIA comprehensive analysis, Emergy evaluation was conducted to real case. As a result, applying Emergy analysis could suggest whether the development is appropriate or not. These indices and the result of this research are expected to be applied decision-making on environmental impact for sustainable development.

Use of recycled aggregates in portland cement concrete construction can offer benefits associated with both economy and sustainability. Testing performed to date indicates that RBMA can be used as a 100% replacement for conventional coarse aggregate in concrete that exhibits acceptable mechanical properties for use in structural and pavement elements, including satisfactory performance in some durability tests. RBMAC is currently not used in any type of construction in the United States. However, use of RBMAC could become a viable construction strategy as sustainable building practices become the norm. Rating systems such as LEED offer points for reuse of building materials (particularly on-site) and use of recycled materials. If renovations at an existing facility call for the demolition of existing brick masonry constructions, the rubble could be included as RBMA in new concrete pavement, sidewalks, or curb and gutter. Other potential uses for RBMAC could include those in the precast concrete industry, particularly in architectural precast concrete applications. In addition to providing acceptable strength and economy, the color of RBMA could be an attractive component of architectural precast concrete panels or other façade components. This paper explores the feasibility of use of RBMAC in several types of sustainable construction initiatives, based upon the findings of previous work with RBMAC produced from construction and demolition waste from a case study site. Guidance for obtaining and using RBMA is presented, along with a summary of material properties of RBMAC that will be useful to construction professionals.

This study analyses customer data from a US online lending platform to empirically document the discriminatory treatment that low- and middle-income borrowers face in financial markets. Researchers are using financial data from nearly 2.93 million loans between 2007~2020 of the Lending Club on the open-source Kaggle platform. We find that thin-filers borrowers, especially those with lower credit scores, receive loans at higher interest rates. This discriminatory treatment undermines financial inclusion and has the potential to increase social inequality. The significance of this research is that it sheds substantial light on the problem of inequality in financial markets and, based on the findings, suggests concrete measures to ensure equitable access to finance for all customers and enhance sustainable financial inclusion. In doing so, we propose a shift towards enhancing the social responsibility of institutions.
