This research proposes a new approach to measure corporate contributions to sustainability called Sustainable Value. With some global corporations which recognize the seriousness of environmental crisis and their social responsibility, enterprises are positively accepting the sustainable management. Also, publication of the sustainability report is proliferating which is showing the enterprise's strategy, activity, result and influence in environmental, economic, social cases to the stakeholder. However, to settle and proliferate this current, it rests with how to evaluate enterprises sustainability in reasonable and reliable figure. In this context, what introduced and taking effects are sustainability report evaluation and awarding system. But the quality of sun stainability report and its content's depth and the evaluation of enterprise's sustainability itself should be distinguished. Because the enterprise which published excellent graded sustainability report is not always the enterprise that is sustainable. Then, how could we prove the result of enterprise's sustainable management based on sustainability report? This paper is to find the answer and to utilize it based on sustainability report, particularly sustainable value model as the central figure.

In this study, a land-based marine closed mesocosm (LMCM) experiment was performed to objectively assess the initial stability of an artificial ecosystem experiment against biological and non-biological factors when evaluating ecosystem risk assessment. Changes in the CV (coefficient of value) amplitude were used as data to analyze the stability of the experimental system. The CV of the experimental variables in the LMCM groups (200, 400, 600, and 1,000 L) was maintained within the range of 20-30% for the abiotic variables in this study. However, the difference in CV amplitude in biological factors such as chlorophyll-a, phytoplankton, and zooplankton was high in the 600 L and 1,000 L LMCM groups. This result was interpreted as occurring due to the lack of control over biological variables at the beginning of the experiment. In addition, according to the ANOVA results, significant differences were found in biological contents such as COD (chemical oxygen demand), chlorophyll-a, phosphate, and zooplankton in the CV values between the LMCM groups(p<0.05). In this study, the stabilization of biological variables was necessary to to control and maintain the rate of changes in initial biological variables except for controllable water quality and nutrients. However, given the complexity of the eco-physiological activities of large-scale LMCMs and organisms in the experimental group, it was difficult to do. In conclusion, artificial ecosystem experiments as a scientific tool can distinguish biological and non-biological factors and compare and analyze clear endpoints. Therefore, it is deemed necessary to establish research objectives, select content that can maintain stability, and introduce standardized analysis techniques that can objectively interpret the experimental results.

This is a comparative study that shows the overall environmental impacts from concrete structures when different compressive strength of concrete applied to structural systems having the same reference flow with different durability. A total of 24 MPa, 40 MPa and 60 MPa cases is analyzed to define the characteristic using end-point perspective LCA methodology including the stages of production, construction, maintenance and disposal. As results, global warming, non-renewable energy and respiratory inorganics problems are the major issues for assessing environmental impacts of concrete products.

Firstly, this study aimed to identify differential characteristics of alternative tourists by comparing socioeconomic and travel characteristics, ecotourism cognition level and intention to participate in ecotourism, and eco-friendly travel attitudes between alternative tourists and mass tourists visiting Jeju Island. Secondly, it aimed to evaluate the possibility of the Jeju experimental forests managed by Warm Temperate Forest Center as an alternative tourism destination. The results shown that alternative tourists had more positive travel attitude and higher level of cognition of ecotourism and intention of participate in ecotourism than mass tourist. The cognition level and the intention of visit the experimental forests were also higher in alternative tourists group. In addition, alternative tourists were more active and participatory in nature-oriented activities, and evaluated themselves culture and nature oriented tourists. Thus, it is required to keep monitoring the alternative tourists' distinctive characteristics and to reflect those in developing and managing alternative tourism destinations.

Physical habitat assessment models based on Instream Flow Incremental Methodology have been developed as a decision making tool to estimate appropriate discharge for environmental flow and water use management. These models, however, require extensive knowledge on various academic disciplines, complicated input data, and empirical data. We propose a Simplified Habitat (SIMHAB) simulation model for the estimation of physical structure of fish habitat and environmental flow at the planning stage. SIMHAB is applied to a river system for which physical and ecological data are available, and its applicability is investigated. Simulated results appeared to be similar to field survey data and those of such models as PHABSIM and River2D. However, SIMHAB requires much less input data. As such, the proposed model, SIMHAB can easily be applicable to river restoration projects including designing of physical habitat, estimation of environmental flow, and water resource management.
