  • For any particular development project or environmental regulations, decision-making criteria is required and conflicts among criteria should be resolved. It is necessary to investigate criteria that government agencies employ in making decisions that influence the environment. The evaluation of alternative development proposals and regulatory measures involves much more than environmental issues. Economic, technical, and social factors should be considered along with environmental impacts when making evaluations. Evaluation should be based on values of all individuals who may be affected by public or private decisions. There are many evaluation methods for determining how individuals and groups value alternative public actions. Numerous weighting-scaling methodologies can be used in such evaluations. These methodologies represent adaptations of multiple-criteria or multiple-attribute decision-making techniques. Environmental risk assessment which accounts for uncertainties in choosing among alternative policies and projects is increasingly used.

  • Like the saying "You can't manage what you can't measure," performance measurement is considered as one of the most important management activities for the organizations in either private or public sector. Performance measurement, however, has thus far relied too much on financial statements. Realizing the importance of a more scientific and comprehensive performance measurement, many organizations have adopted several different systems in order to objectively estimate their balanced performance results. The Balanced Scorecard (BSC) has become a popular means to measure performance. But the BSC has also received some criticisms. In this paper four limitations in the use of the BSC are discussed : BSCs focus on unidirectional causality, are unable to distinguish delays between actions and their impacts on performance, integrate insufficiently strategy with operational measures, and lead to internal biases. We propose a system dynamics approach with causal loop diagram(CLD) to develop a Dynamic BSC in order to overcome these limitations. The results suggest that developing a BSC with system dynamics is a promising approach to supplement existing BSC frameworks.

  • Despite the importance of Creating Shared Value(CSV), few research has been conducted to understand it. Filling in this existing void, this study was an attempt to provide a clear understanding about what triggers airline customers' decisions according to the airline company's CSV activities. Through this study, we investigated the relationship among CSV, trust, image, and loyalty. An online survey was used as a method to collect data. Through the CFA, we confirmed the adequate level of reliability and validity of the measures. The structural model was found to include an acceptable fit to the collected data. The findings from the structural analysis revealed that CSV exerted and immense on trust and image. Also, trust was significantly associated with image and loyalty while the image was highly associated with loyalty. Based on the findings presented above, implications for practitioners and researchers are stated.

  • Multi-criteria decision making is deducing the relative importance in the criterion of decision making and each alternative which is able to making a variety of choices measures the preferred degree in the series of low-raking criterions. Moreover, this is possible by synthesizing them systematically. In general, a fundamental problem decision maker solve for multi-criteria decision making is evaluating a set of activities which are considered as the target logically, and this kind of work is evaluated and synthesized by various criterions of the value which a chain of activities usually hold in common. In this paper, we are the eigenvector methods in weights calculating. For the purpose of making optimal decision, the data of five different car models are used. For computing, we used Visual Numerica Version 1.0 software package.

  • The purpose of this study is to collect and analyze their opinions to found solutions for reducing safety accidents since it is important to educate the students to recognize the importance of safety. We surveyed 350 students from mechanical and metal engineering departments of an engineering high school located in Seoul, and divided them in two categories and asked them about prevention of safety accidents in laboratories. It is found that further directions and educations are needed for the students as to emergency measures in case of safety accidents. Safety education before laboratory classes is crucial, helpful and effective for prevention of safety accidents. Facility factors that further education is needed for students who don't experiments in orderly manner.

  • A module or independent subtree is a part of a fault tree whose child gates or basic events are not repeated in the remaining part of the fault tree. Modules are necessarily employed in order to reduce the computational costs of fault tree quantification. This quantification generates fault tree solutions such as minimal cut sets, minimal path sets, or binary decision diagrams (BDDs), and then, calculates top event probability and importance measures. This paper presents a new linear time algorithm to detect modules of large fault trees. It is shown through benchmark tests that the new method proposed in this study can very quickly detect the modules of a huge fault tree. It is recommended that this method be implemented into fault tree solvers for efficient probabilistic safety assessment (PSA) of nuclear power plants.

  • Contemporary Architecture is showing many aspects on the ground of ecological paradigm, while, searching for a new architectural direction to make importance of environment that has been still little accounted of a subject of discussion. And 'sustainability'will become a central concept of a Contemporary architectural topic, continuously. With a demand of the time, ecological inclinations have been started to develop a collective low-rise housing project. It is going to expands several fields, but for reasons of social economic activity for human fundamental being, potentialities of basic problem solution are enough for ecologyㆍenvironment, but distinct direction and measures are still not obvious conditions. This study is for healing restoration in global environment, with architectural approach, through analyzing relation between ecological architectural space and nature, and abstracts various inter-relational aspect's specific character. the purpose of this study is another approach of intimate relation of ecological architecture and nature. Therefore, this study is significant to be on the search for a start to suggest a new point of view to ecological architectural space.

  • With limited resources, proper allocation of the national R&D budget is very crucial matter for reinforcing the national competence, and the importance of selecting strategic R&D fields have been increasingly emphasized by technology policy-makers and CTOs. This paper deals with technology relevance/cluster analysis, which measures technological dependency and relevancy among technologies, and how it can be used for selecting the strategic R&D fields especially satisfying SMEs(small and medium enterprises)' specific needs. As a result of this study, technology-product tree composed of 7 major technology fields, 22 clusters, 41 groups, 335 core-need technologies and hundreds of related business items are produced that can be used for designing SMEs' R&D/business portfolio as well as R&D investment decision-making of the Ministry of Small and Medium Business Administration.

  • Legal regimes of major countries actively involved in wetland programs including USA, Japan, Germany, Netherlands, and Denmark, show that these leading nations have developed their own legal regimes and policies for the conservation and restoration of wetlands since early 1990s. The main feature of their position is to preserve, create and restore wetlands, including tidal flats. However, this approach, so called 'mitigation' policy, is thus far, not a fully established policy but an evolving one. For Korea, there are only a few laws and policies which hint at the importance of creating coastal wetlands as a conservation measure, however, most of those systems only exist as vague provisions which lack any tangible and compulsory implementing procedures and technical guidelines. It seems that it is necessary to strengthen the legal measures for conserving coastal wetlands in Korea including specifying economic assessment methods and funding sources for the creation, restoration and rehabilitation of tidal flats to firmly establish a national wetland mitigation policy.
