  • LCA is nowadays getting popular as a tool to assess the environmental impacts. We can assess the environmental impacts of products and also compare the environmental performance between products with LCA. Furthermore, the LCA results can be used for designing eco-friendly products. But LCA needs an enormous amount of data collection, calculations of energy and material balance. which required to spend pretty much time and cost. However, If we use Input-Output Analysis, There is a lot of advantages that we can save time and cost to calculate and also analyze energy-material balance more comprehensively. Therefore, we implemented the fundamental research of the environmental impact assessment on railway system using life cycle inventory analysis and Input-Output Analysis method.

  • The objectives of this study were to determine the recognition of food waste, school lunch leftovers and satisfaction toward school lunch in middle school students in Seoul. Four hundred students were surveyed beginning April, 2007. The results are summarized as follows. The primary means in which students learned about environmental pollution were 'video media' (54.7% males, 39.2% females) and 'by teachers' (23.2% males, 33.0% females). The primary effects on food habits after participating in the school lunch program were 'having a balanced diet' (23.3%) in the females, and 'decreased intake of junk food' (24.9%) in the males. The serving sizes for cooked rice, soup, and meat were higher in the females (3.46, 3.46, and 2,91, respectively) than the males (3.18, 3.29, and 2.73, respectively). The primary school lunch leftovers for one week were cooked rice (4.55), meat (4.35), kimchi (3.84), fish (3.60), vegetables (3.38), and soup (3.08). Importance-performance analysis of the school lunch meal indicated that good taste had high importance, but low performance. Nutritional balance, food safety, cleanliness of tableware and supplies, clean uniforms of employees, and cleanliness of the dining area had both high importance and performance.

  • The purpose of this study were to make a comparison with the level of environmental consciousness between the livestock farmer and the reference groups( peasant, office worker, housewife and student) and to identify the variables which have an influence on the level of their role performance for environmental protection & preservation. Data for this study were collected from 822 cases including the livestock farmer(109), the peasant(67), the office worker(140), the housewife(119) and the student(356). The SPSS software program and statistics such as frequencies, x2, ANOVA, multiple regression analysis, Chronbach's ${\alpha}$ and factor analysis were used to analyze the data for this study. The major findings of this study were as follows: 1. The pro-environmental attitude score(environmental sensitivity and attitude of environmental protection & preservation) the groups of office worker and housewife is shown higher than the groups of livestock farmer, peasant and student. 2. The consciousness of environmental problem is relatively low to the group of the livestock farmer compared with the reference groups. 3. As a result of multiple regression analysis, four determinants such as locus of control, lifestyle, environmental sensitivity, and knowledge of environmental issues explained 38.8% of the livestock farmer's role performance for the environmental protection & preservation.

  • In this study, remodeling projects are perceived as a sustainable urban management policy to boost the value of old apartments and stimulate urban regeneration and development. To evaluate the physical environmental performance of external spaces of remodeled apartments, an evaluation model was developed. After applying it to the target places, the following results were obtained. First, analysis of the external space change index of the target apartments revealed that institutional standards are necessary in line with the building arrangement type, parking lot expansion method, and changes in the building-to-land ratio. Second, the score ratio as to the external space change index performance is as follows: safety (48.30); pleasantness (25.90); convenience (18.90); eco-friendliness (14.90). In other words, "safety" had the biggest score ratio. Third, to boost the external space performance of remodeled apartments, the needs of residents and neighboring environmental plans should be considered from a communality standpoint.

  • Reinforced concrete (RC) shear walls are commonly used for building structures to resist seismic loading. While the RC shear walls can have a high load-carrying capacity, they tend to fail in a brittle mode under shear, accompanied by forming large diagonal cracks and bond splitting between concrete and steel reinforcement. Improving seismic performance of shear walls has remained a challenge for researchers all over the world. Engineered Cementitious Composite (ECC), featuring incredible ductility under tension, can be a promising material to replace concrete in shear walls with improved performance. Currently, the application of ECC to large structures is limited due to the lack of the proper constitutive models especially under shear. In this paper, a new Cyclic Softening Membrane Model for reinforced ECC is proposed. The model was built upon the Cyclic Softening Membrane Model for reinforced concrete by (Hsu and Mo 2010). The model was then implemented in the OpenSees program to perform analysis on several cases of shear walls under seismic loading. The seismic response of reinforced ECC compared with RC shear walls under monotonic and cyclic loading, their difference in pinching effect and energy dissipation capacity were studied. The modeling results revealed that reinforced ECC shear walls can have superior seismic performance to traditional RC shear walls.

  • Environmental Performance Evaluation(EPE) is a key process of Corporate Environmental Management. This paper presents the results of an empirical survey on the status of current practices in EPE of Korean firms. Based on a corporate environmental management(CEM) model, which is initially developed by Hibbitt and Kamp-Roelands(2001) and modified in terms of EPE, the survey is peformed on the population of Korean firms, which are composed of firms certified as "environmentally friendly" by Korean government and/or certified under Is014001, and compares its results with those of Europe's. Although the relatively low response rate and some methodological limitations makes us be cautious about the interpretation, the results shows many interesting aspects of the current states of Korean firms' EPE practices. That is, the levels of EPE implementation in the environmentally-leading companies of Korea are almost the same as that of European companies, I. e., in the-final-part-of-developing-stage (3rd stage) level of the CEM model. It is also shown that as In Europe's case, Korean firms are also moving slower in external relationships than in internal control and management, are more developed in the parameters like environmental policy, Internal control, Information system, which are requirements of certification under Is014001, than in parameters like life cycle analysis and full cost accounting, which requires more research efforts, etc.orts, etc.
