As environmental concerns continue to grow, green supply chain management (GSCM) is attracting attention as an element of competitive advantage for companies. This study examined internal GSCM practices to show how they influenced the end-point of the supply chain from the perspective of the end-consumer. It identified the effects of environmental concerns on consumer purchasing behavior mediated by the company image of internal GSCM practices. Data were collected through an email survey of Korean consumers. Reliability and validity were verified using SPSS 18.0. Cronbach's alpha, and confirmatory factor analysis. The results showed that environmental concerns had a positive impact on such practices, and the image of internal GSCM practices was found to have a significantly positive effect on consumer purchasing behavior. Companies will have to actively reflect environmental factors in their operational activities, and GSCM implementation will become a necessity. A positive image of internal environmental management and eco-design, which are key elements of internal GSCM practices, strengthened the company's eco-friendly image and ultimately affected consumer purchasing behavior. This suggests that it is important for companies to evaluate their environmental attitude and make eco-friendly products from a consumer's perspective, making it a differentiation strategy for a company in building an eco-friendly corporate image.

This study analyzed the effect of Corporate Social Responsibility and ESG (Environmental, Social and Governance) score on information asymmetry from the perspective of investors, who are important stakeholders of the company. For KOSPI-listed companies from 2017 to 2020, the effect of ESG overall score and each item score (E, S, G) on the bid-ask spread, which is a proxy for information asymmetry, was confirmed. The results are as follows. First, the increase in corporate CSR activities resulted in lowering information asymmetry of investors. It was found that the higher the ESG score, an indicator of CSR activity, the lower the bid-ask spread, which is a proxy variable for information asymmetry. Second, as a result of analysis using ESG scores for each section, information asymmetry decreased as companies with higher scores in the environmental (E) and social (S) aspects, while the governance (G) score did not have a statistically significant effect. The analysis confirmed that corporate CSR activities can contribute to improving market efficiency by resolving information asymmetry of investors and convergence of the stock market into a state of equilibrium. This means that the company's CSR activities are reflected in the investment decision-making, which suggests that the company should consider the investor as a stakeholder in decision-making related to CSR activities.

The purpose of this research is to examine the relationship between corporate social responsibility (CSR), green supply chain management (GSCM) practices, and business performances. After reviewing the extensive literature, we developed a research model including five constructs: CSR, GSCM practices, environmental, economic and operational performances. We conducted the statistical analyses based on the primary data collected from a survey questionnaire, responded by 93 different company managers in the Republic of Guatemala. Furthermore, we utilized structural equation modeling to analyze the data and to test the hypotheses. The results of the analyses showed that there is a significant influence of CSR on the adoption of GSCM practices. It was also found that GSCM practices have a significant influence on environmental, economic and operational performances. In addition, environmental performance has a significant impact on economic and operational performance. Finally, GSCM has a mediating role on the relationship between CSR and environmental and economic performance, but not with operational performance.

The sludge, a waste of brewery industries, was examined for potentials as a natural organic fertilizer (or soil conditioner) for lawn. Trial products were measured for changes of physical, chemical properties in laboratory and seed germination and seedling growth in green house were also tested. The results are as the following:1The sludge from distilled liquor brewery contained high quantity of organic matter which had proper physical and chemical properties for lawn fertilizer (natural organic fertilizer, soil conditioner, top-dressing mix) . It showed good characteristics in handling and capabilities to be developed as commercial products for golf courses. 2.Sludge from beer company needs proper treatment to improve physical properties for futher degradiation. It is because aggregation of the sludge particles prevented microbial activities and changing to soluble form. 3.Green carbon can be used as carbon source for organic fertilizer production using brewery sludge, but it should not contain wood extract which inhibit seed germination and seedling growth.

Waste glass disposal causes environmental problems in the cities. To find a suitable green environmental solution for this problem low cost adsorbent in this study was prepared from waste glass. An effective new green adsorbent was synthesized by hydrothermal treatment of waste glass (WG), followed by acidic activation of its surface by HCl (WGP). The prepared adsorbent was characterized by scanning electron microscopy (SEM), X-ray fluorescence (XRF), X-ray diffraction (XRD), and BET surface measurement. The developed adsorbent was used for the removal of heavy metals (Cd, Cu, Fe, Pb and Zn) from well water. Batch experiments were conducted to test the ability of the prepared adsorbent for the removal of Cd, Cu, Fe, Pb and Zn from well water. The experiments of the heavy metals adsorption by adsorbent (WGP) were performed at different metal ion concentrations, solution pH, adsorbent dosage and contact time. The Langmuir and Freundlich adsorption isotherms and kinetic models were used to verify the adsorption performance. The results indicated high removal efficiencies (99-100%) for all the studied heavy metals at pH 7 at constant contact time of 2 h. The data obtained from adsorption isotherms of metal ions at different time fitted well to linear form of the Langmuir sorption equation, and pseudo-second-order kinetic model. Application of the resulted conditions on well water demonstrated that the modified waste glass adsorbent successfully adsorbed heavy metals (Cd, Cu, Fe, Pb and Zn) from well water.

The Seoul Housing Corporation pronounced an alternative design competition and a bidding for Eunpyeong New Town in December of 2004. At first many construction companies were interested in the first New Town Project. But at last a few companies had proposed the alternative design and construction cost. This project needed a conjunction of design ideas and technology know-hows. And the client wanted the brand power of construction company. Ultimately the Corporation hoped that the first New Town Project will end up with high quality successfully. This competition had started with the original construction drawings. Then it needed some alternative ideas and the lowest cost. There were two drawings of non changeable part and changeable part. Non changeable parts are structure like housing unit plan, underground parking lots. Changeable parts are outdoor layout, interior design and building facade. So we tried all ideas of landscape technology and design principles within limited guidelines. The author applied new technology like tilted rooftop greening and sustained container greening on high-rise apartment house. This green technology will be the first trial in Seoul and in the world as well. Daewoo Corporation have accumulated greening technology through the researches by national funding since 2002. Through this New Town Project the green technology will go forward step by step.
