  • This paper is intended to deduce the planning elements of Eco-village through theory contemplation and preceding researches in order to be used as practical data of resident participating Eco-village by contemplating characteristics demonstrated in planning element utilization methods within the village. Resident participating Eco-village aims for residents who will reside in the relevant village to participate from village plans to construction. Unlike other Eco-village, residents of resident participating Eco-village make decisions autonomically through planning direction, planning elements, discussions and meetings, which are uniquely distinctive from other Eco-villages. It appears, however, that analysis on the planning element utilization methods of resident participating Eco-village is inadequate. There are various methods of village resident participation, and the methods cannot rule out the close relationship with planning elements. Hence, programs for resident participation should be devised at the time of village planning. Resident participating Eco-village should suggest measures and guidelines through finding problems in order to implement sustainable and environment-friendly life that prevent a retrograde step.

  • Given the critical importance of enhancing the level of ESG practices, the current research examines the impact of credit card users' pro-environmental characteristics (i.e., environmental self-accountability, eco-label involvement) on their satisfaction with credit card benefits related to green life. That is, this research investigates whether consumers' satisfaction with green credit card benefits varies depending on their environmental self-accountability and eco-label involvement. Specifically, we predict that (1) for consumers with high (vs. low) environmental self-accountability, their satisfaction with credit card benefits related to green life will be higher (hypothesis 1); and (2) when consumers have high (vs. low) eco-label involvement, they will be more likely to be satisfied with credit card benefits related to green life (hypothesis 2). An online survey (N = 293) was conducted to test the two hypotheses. In support of the hypotheses, the results indicate that (1) respondents who had high (vs. low) environmental self-accountability were more satisfied with credit card benefits related to green life, and (2) respondents with high eco-label involvement, as compared to those with low eco-label involvement, reported greater satisfaction with credit card benefits related to green life. We suggest an important insight into how credit card companies approaching ESG issues can increase their consumers' satisfaction with green credit card benefits, considering consumers' individual characteristics such as environmental self-accountability and eco-label involvement.

  • Most of eco-friendly agrifood processing enterprises in Korean rural area are small and medium-sized business. For this reason, it's hard for eco-friendly agrifood processing enterprises to neither analyze business performance for efficient business management nor establish their own business plan for rational decision-making. Therefore it's necessary to design effective mathematical programming model and to make practical application which can support rational management decision-making ensuring the stable business activity of eco-friendly agrifood processing enterprises. Accordingly this paper focuses on the designing and its application of multi-objective mathematical programming model using goal programming to support rational decision-making of eco-friendly agrifood processing enterprise. Hansalimanseongmachum Food Inc. which runs soy bean processing business making tofu based on regional-based soybean farms around Anseong City will be the specific case to apply multi-objective mathematical programming model in practice. And it will suggest measures to support rational management decision-making of other eco-friendly agrifood processing enterprises.

  • This study examined the effects of the epoxidized castor oil (ECO) and $Al_2O_3$ content on the thermal stability and fracture toughness of the diglycidylether of bisphenol-A (DGEBA)/ECO/$Al_2O_3$ ternary composites using a range of techniques. The thermal stability of the composites was decreased by the addition of ECO and $Al_2O_3$ nanoparticles. The fracture toughness of the composites was improved significantly by the addition of ECO and $Al_2O_3$ nanoparticles. The composite containing 3 wt % $Al_2O_3$ nanoparticles showed the maximum flexural strength. Scanning electron microscopy (SEM) revealed tortuous cracks in the DGEBA/ECO/$Al_2O_3$ composites, which prevented deformation and crack propagation.

  • Purpose: NBS (Natural-based Solutions) characteristics as eco-friendly hotels were divided into eco-friendly indoor and outdoor to structurally verify the relationship between customers' perceived eco-friendly value, psychological well-being, customer satisfaction, and pro-environmental behavioral intention. Research design, data and methodology: This survey conducted responses to customers who had experience using eco-friendly hotels for the past two years. SPSS 22.0 and AMOS 22.0 statistical programs were used for the collected questionnaire data. First, frequency analysis and confirmatory factor analysis (CFA) were verified, and structural correlation between variables was verified by covariance matrix structural equation (CB-SEM). Result: First, NBS was found to have a significant positive (+) effect on perceived eco-friendly value and psychological well-being. Second, psychological well-being was found to have a significant positive (+) effect on customer satisfaction and eco-friendly behavioral intention. Finally, Hypothesis 3 was accepted as perceived eco-value showed a significant positive (+) effect on eco-friendly behavioral intention, but Hypothesis 2 was rejected because it did not have a significant effect on customer satisfaction. Conclusions: theoretical and practical implications for the impact of NBS as an eco-friendly hotel on customers' eco-friendly behavior can be provided, as well as basic evidence for establishing efficient management strategies for hotel companies.

  • Consortia demonstrated the high capacities of anaerobic degradation of various aromatic compounds, which were successfully enriched from gley paddy soils under different conditions. Phenol and cresol was decomposed anaerobically using nitrate, ferric oxide or sulfate as electron acceptors. Biphenyl was degraded to $CO_2$, especially without addition of external electron acceptor. Alkylphenols with middle length of alkyl chain, were co-metaboliocally degraded with the presence of hydroxylbenzoate as the co-substrate under nitrate reducing conditions. The microorganisms responsible for the anaerobic co-metabolism was Thauera sp. Reductive dechlorination activity was also observed for polychlorophenols, fthalide, polychlorinated biphenyls, polychlorinated dibenzo-p-dioxins with the presence of lactate, formate or $H_2$ as electron donor. The fthalide dechlorinator was classified as Dehalobacter sp. Coupling of two physiologically-distinct anaerobic consortia, aromatic ring degrader and reductive dechlorinator, resulted in the mineralization of pentachlorophenol under anaerobic conditions. These results suggested that gley paddy soils harbored anaerobic microbial community with versatile capacity degrading aromatic compounds under anaerobic conditions.

  • Recently, as the number of landscaping plant nurseries have increased, environmental problems such as topographical damage due to indiscriminate changes in land use, increased non-point pollution, and increased impervious areas are also occurring. In this study, we propose eco-friendly facilities and a detailed maintenance manual that can enhance the eco-friendliness and scenic beauty of landscaping plant nurseries that are increasingly located near cities. By exploring previous reports on eco-friendly facilities and related laws, we cataloged the types of eco-friendly facilities, and by referring to examples of eco-friendly facilities introduced in overseas cases and the environmental functions of agriculture, we cataloged the types of eco-friendly facilities suitable for introduction in plant nurseries. The selected facilities are rain gardens, tree boxes, vegetated filter beds, bio-retention, infiltration trench, infiltration tanks, permeable pavements, and sand filtration systems. The maintenance tasks of eco-friendly facilities were categorized and management plans were proposed, which is expected to be utilized as a basic data to prepare eco-friendly space planning and operation management plans when creating a landscape plant nurseries in the future.

  • This research intends to find the concept of eco-village in suburban area which various people can experience. For this, we established general ideas through theoretical reflections, and found an objective of suburban eco-village through functional practices. According to the research, a composition of eco-village to reduce the environmental load consists of three major functions. First, by forming traditional meanings of eco-village community, it creates eco-friendly life through energy saving and resource recycling. Second, it functions as relieving the stress of the urbanites and healing their mind and body in the nature of formed eco-village community. Finally, the implementation of eco-village is an idea of group of people who tends to live with nature. Thus, by recovering the nature and by preserving the nature with eco-friendly concept, it will be developed by a place where people can experience the importance of nature. However, these three functions should reflect regional characteristics sufficiently, and through saving and utilizing the history, culture and ecological resources of the regions, it gives positive support to local natives' sustainable life. Consequently, it will show the right direction of development of suburban eco-village through each case analysis of these three functions.

  • 최근 폭증하는 해상물동량으로 인해 선박은 날로 대형화되며 현재 우리나라에서는 이러한 추이에 대응하기 위해 초대형 항만건설이 서둘러 진행되고 있으며 그 중 일부는 이미 부분적으로 완성되어 운영 중이거나 계속적인 확장이 예정되어있다. 초대형 항만의 경우 항 정온도 확보를 위해 대형 직립형 방파제가 수반되기 마련이나 비교적 높은 반사율로 인해 장주기의 파랑에 취약한 구조적 문제를 지닌다. 장주기 파랑의 효과적 제어를 위해 본 고에서는 아치형 curtain wall과 유수실로 구성된 된 장파 제어체 -Eco-breaker 2- 가 제시되며 Eco-breaker 2의 수리특성을 수치적으로 규명하였다. 수치모형은 가장 강건한 파랑모형인 Navier-Stokes Eq.과 SPH(Smoothed Particle Hydrodynamics), LES(Large Eddy Simulation) 기법에 기초하여 구성하였다. 수치모형의 검증을 위한 수리모형실험도 병행하였다. 수치모의 결과 Eco-breaker 2는 유수실 내부에 생성되어 아치형 curtain wall 전면 수역과 유수실을 주기적으로 넘나드는 대규모 구조적 와로 장파를 효과적으로 제어할 수 있었다. 또한 대규모 구조적 와의 생성 영역과 세기는 내습하는 파랑의 주기에 종속하며 유수실 체류시간이 입사파 주기의 반을 하회하는 경우 반사계수는 최대 0.18까지 낮아진다. 이러한 결과는 Eco-breaker 2가 환경친화적 항의 개발에 적극적으로 활용될 수 있음을 시사하는 것으로 이를 위해 그 구체적 제원도 함께 제시하였다.
