  • This study was performed to explore the adolescents\` conception and practice of Hyo(filial piety). Fifteen teams of 500 adolescents were allowed to discuss about Hyo for two hours and the team leaders presented what they had discussed. The subjects were 330 elementary school students, 130 middle school students, and 40 high school students. The findings from the discussion and presentation were as follows: First, the adolescents\` conceptions of Hyo were different in the stages of schools. Elementary school students thought that they should do Hyo because they got lots of mercy from parents. Middle and high school students both thought that Hyo came from mutual(parent-children) understanding, but they showed somewhat different view about what disturbed the mutual understanding. Middle school students pointed the deficiency of parents'self-disclosure as a disturbing factor while high school students pointed the deficiency of adolescents'understanding of their parents. Second, the behavioral items that the subjects suggested as Hyo were analysed by the 12 Subvirtues of Adolescent's Hyo which was classified by Chung et al.(1996a). Adolescents could not propose any behavioral items for Thanks, Ancestor Worship, and Ecological Equilibrium, and some items for Advising Parents and Thrift. A lot of items were suggested for Moral Training, Supporting (Parents), Consorting (Parents), Respecting (Parents), Establishing Oneself, and Following Parents.

  • There are more interests and studies to change the buildings into eco-friendly spaces as the present age recognizes nature-friendly environment more and more. In response to this trend, the government reinforces regulations for the variety of the eco-friendly buildings using a certification system. The eco-friendly certification system which was started only for residing since 2002, and this has been now for schools that are the spaces of the students who will lead the future since March 2005. The purpose of this study is to help understanding of the eco-friendly buildings, and to popularize and activate those as developing and making up for the classification system, evaluation items, detailed standards to evaluate them more precisely by analysing eco-friendly planning features and data of the eco-friendly certificated schools. This study selected 15 eco-friendly certified schools among the schools certified by the Ministry of Land, Transport, and Maritime Affaires since 2005, and analyzed evaluation result. After the analysis, I had a thorough grasp of the point distribution of the each building, analyzed the cause of the low points or no points, and tried to find the improvements. There should be continuing adjustment and complement for the evaluation items and detailed standards, and these should be applied to models as well as certified schools. Active public relations are also needed to educate the public and elevate their participation.

  • In order to investigate food purchase frequency of elementary school children and its related ecological factors, 431 4th, 5th and 6th grade elementary school children and their mothers, living in Seoul and Daejon, small city and rural area of Chungnam Province, were participated in this study. The subjects and their parents were surveyed by a self-recording questionnaire about food purchase frequency and some ecological factors. Average height and weight of the subjects by gender and grade were similar to or a little bit more than the 1998 Korean Growth Standard. According to relative body weight, 30.6% and 10.8% of the subjects belonged to under-weight and obesity categories, respectively. Of the subjects, 46.9% used PC telecommunication or internet, 53.8% of them used it for less than an hour per day, and 46.4% watched TV for 2 to 4 hours a day. About 42% of the subjects spent 500 Won or less daily to buy snacks. A half of the subjects took snacks once a day because of hunger. Mothers' nutrition knowledge score was averagely 8.16 out of 13 full score and the average attitude score was 43.22 out of 50 full score. Foods purchased more than once a week were milk and yoghurt, cookies, ice-cream, ramyun, and gum in order. Family income, parents' education level, mothers' nutrition knowledge and food attitude score, students' snacking frequency and TV watching time showed significant correlations with purchase frequencies of some individual food items. In conclusion, the elementary school children considered taste most important rather than nutrition in buying snacks and most frequently bought carbohydrate foods and concentrated sugars except milk. Ecological factors such as mothers' nutritional knowledge and food attitude, TV watching time and snacking frequency had influenced the children's food purchase frequency. Accordingly, it is necessary to educate both children and their mothers about good food purchase and the importance of snacking.

  • Climate change is considered a severe global problem closely related to carbon storage. However, recent urbanization and land-use changes reduce carbon stocks in terrestrial ecosystems. Recently, the role of protected areas has been emphasized as a countermeasure to the climate change, and protected areas allow the area to continue to serve as a carbon sink due to legal restrictions. This study attempted to expand the scope of these protected areas to an evaluation-based environmental spatial information theme map. In this study, the area of each grade was compared, and the distribution of land cover for each grade was analyzed using the Ecological and Nature Map, Environmental Conservation Value Assessment Map and Urban Ecological Map of Sejong Special Self-Governing City. Based on this, the average carbon storage for each grade was derived using the InVEST Carbon model. As a result of the analysis, the high-grade area of the environmental spatial information generally showed a wide area of the natural area represented by the forest area, and accordingly, the carbon storage amount was evaluated to be high. However, there are differences in the purpose of production, evaluation items, and evaluation methods between each environmental spatial information, there are differences in area, land cover, and carbon storage. Through this study, environmental spatial information based on the evaluation map can be used for land use management in the carbon aspect, and it is expected that a management plan for each grade suitable for the characteristics of each environmental spatial information is required.

  • This work was designed for the Green Fund Aid 2004 of Korea Forest Service. It won the prize and has been constructed. We can have an opportunity to play a leading role in improving partnership with participation of local communities, promoting environmental education, and enhancing the environmental quality by constructing biotops in urban areas where energy flow in the ecosystem is not balanced. This design includes 'citizen participation process' and 'local community partnership' that is expected to promote local community participation in the process of design. This work suggests that biotope construction with citizen involvement and community partnership plays an important role not only in design items but also in the revitalization of local community. This sort of design process could not be fully achieved without cooperation with stakeholders - environmental specialists, local authorities, relevant societies, schools, teachers, parents of students.

  • This study was performed to propose the site selection plan for the restoration of the target Narrow-mouth Frog(Kaloula borealis) habitat, and has developed the AHP model to select the optimal site for narrow-mouth frog habitat restoration on the basis of the narrow-mouth frog Habitat Suitability Index (HSI) items (factors and variables). The assessment areas were established by the narrow-mouth frog HSI factors such as space, feed, cover, water(breeding), threatening factors and others, and the sub-assessment items by each assessment area were established based on the narrow-mouth frog HSI variables. The weighting values of the assessment areas and items were calculated by the developed AHP method. The weighting values of the 5 assessment areas were arranged in order as cover(0.283), water(breeding)(0.276), feed(0.230), space(0.147), and threatening factor(0.064). The final weighting values of the 14 assessment items were arranged in order of height as low-rise grassland(0.190), soil quality(0.178), and stones and between the stones(0.105). The scoring criteria according to the assessment items and factors were marked and applied by equal intervals considering the criteria by HSI items of the narrow-mouth frog and finally the scoring criteria diagram has been proposed for the optimal site selection of the narrow-mouth frog habitat restoration.

  • The purpose of this study is to construct an outlook model that is consistent with the "Fisheries Outlook" monthly published by the Fisheries Outlook Center of the Korea Maritime Institute(KMI). In particular, it was designed as a partial equilibrium model limited to abalone items, but a model was constructed with a dynamic ecological equation model(DEEM) system taking into account biological breeding and shipping time. The results of this study are significant in that they can be used as basic data for model development of various items in the future. In this study, due to the limitation of monthly data, the market equilibrium price was calculated by using the recursive model construction method to be calculated directly as an inverse demand. A model was built in the form of a structural equation model that can explain economic causality rather than a conventional time series analysis model. The research results and implications are as follows. As a result of the estimation of the amount of young seashells planting, it was estimated that the coefficient of the amount of young seashells planting from the previous year was estimated to be 0.82 so that there was no significant difference in the amount of young seashells planting this year and last year. It is also meant to be nurtured for a long time after aquaculture license and limited aquaculture area(edge style) and implantation. The economic factor, the coefficient of price from last year was estimated at 0.47. In the case of breeding quantity, it was estimated that the longer the breeding period, the larger the coefficient of breeding quantity in the previous period. It was analyzed that the impact of shipments on the breeding volume increased. In the case of shipments, the coefficient of production price was estimated unelastically. As the period of rearing increased, the estimation coefficient decreased. Such result indicates that the expected price, which is an economic factor variable and that had less influence on the intention to shipments. In addition, the elasticity of the breeding quantity was estimated more unelastically as the breeding period increased. This is also correlated with the relative coefficient size of the expected price. The abalone supply and demand forecast model developed in this study is significant in that it reduces the prediction error than the existing model using the ecological equation modeling system and the economic causal model. However, there are limitations in establishing a system of simultaneous equations that can be linked to production and consumption between industries and items. This is left as a future research project.
