The purpose of this study is to identify the level of children's consciousness and behavior for the environmental conservation, so that provides some fundamental information for the overcome of environmental crisis and reinforces a consumer education for the childrens at home. The subjects were randomly selected form the 4th, 5th, and 6th grade of elementary school students, in April, 1996, Seoul, Korea. The 1342 data obtained were analyzed by Mean, t-test, ANOVA, duncan's Multiple Rang Test, Pearson correlation, and Regression. The major findings were as follows: 1) The average level of children's consciousness for the environmental conservation was relatively low, which was 1.79. There were significantly differences on the children's consciousness for the environmental conservation, according to student's grade level, housing type, parent's education, household income, and the level of consumer socialization. 2) The average level of children's behavior for the environmental conservation was low, which was 2.36. There significant differences on children's behavior of environmental conservation, according to student's sex, grade level, housing type, parent's education and occupation, household income, and consumer socialization. 3) There were significant relationships between children's consciousness and behavior for the environmental conservation. 4) The most influential variable for children's consciousness and behavior of the environmental conservation was consumer socialization. As we see above, this study concludes that consumer environmental education should be reinforced for the children in the home, so that they involved in the environmental activities and have an early experience.

This study was carried out to lead the scientific management of the urban forest by estimating the forest environment. Forest environmental information was constructed using IDRISI system based on survey data, soil, plant, and digital elevation data. Forest environmental information was consisted of soil depth, soil organic content, soil hardness and parent rock as a soil environmental factor, and forest community, tree age, crown density as a plant environmental factor. Plant activity and topographic environment also were analyzed by using remote sensing data and digital elevation data. Environmental function of urban forest was estimated based on results of soil conservation and forest productivity. 70% of urban forest is located in elevation of lower than 200m and 55% of forest area have the slope of lower than 15 degree. Analyzed soil conservation status and forest productivity were almost the same as the soil chemical properties of collected soil sample and the vegetation index estimated using remote sensing data, respectively. Thus, the constructed forest environmental information could be useful to give some ideas for management of urban forest ecosystem and establishment of environmental conservation planning, including forests, in Taejon. The best forest environmental function was appeared at the natural ecology preservation zone. Current natural parks and urban parks were appeared to establish the environmental conservation plan for further development. The worst forest environmental function was appeared at the forest near to the industrial area and an overall and systematic plan was required for the soil management and high forest productivity because these forest was developing a severe soil acidification and having a low forest productivity.

Corylopsis coreana Uyeki is endemic species in the Korean peninsula and is designated a Category Endangered Plant Species by the Wildlife Protection Act of South Korea. We developed the plan and cooperative model within the local community for the species conservation. In order to carry out this plan we first investigated the ecological characteristics of the species. The species shows patterns of discontinuous distribution and is coupled with the unusual feature of only growing on northern exposed slopes. Although Corylopsis coreana is cut the stem every year, many new sprouts are still grown from the root. Natural germination of the seed occurs only on north-facing slopes, but not on south-facing slopes at spring. That is, the species is highly influenced by soil moisture until the seedling stage has been reached. This factor limits the distribution of the species. When saplings are planted on south-facing slopes, they grow well. The information we gathered greatly helped with efforts to draw up conservation plans. In addition, when the information was shared with the local community, builders and residents showed great interest and displayed a will to help with conservation efforts. Therefore, a cooperative model within the local community was drawn up for the conservation of the species. Accordingly this model could be applied at mitigation measure at environment impact assessment.

The Gold-spotted pond frog, Rana plancyi chosenica, designated as a vulnerable species by IUCN Red list. This species is a typical example facing local population threats and extinction due to human activities in South Korea. A strategic conservation plan for this endangered species is urgently needed. In order to provide information for future conservation planning, accurate information on the genetic diversity and taxonomic status is needed for the establishment of conservation units for this species. In this study, we used a molecular genetic approach using the mitochondrial cytochrome b gene and control region sequences to find the genetic diversity of gold-spotted pond frogs within South Korea. We sequenced the mitochondrial DNA cytochrome b gene and control region of 77 individuals from 11 populations in South Korea, and one from Chongqing, China. A total of 15 cytochrome b gene haplotypes and 34 control region haplotypes were identified from Korean gold-spotted pond frogs. Mean sequence diversity among Korean gold-spotted pond frogs was 0.31% (0.0-0.8%) and 0.51% (0.0-1.0%), respectively. Most Korean populations had at least one unique haplotype for each locus. The Taean, Ansan and Cheongwon populations had no haplotypes shared with other populations. There was a sequence divergence between Korean and Chinese gold-spotted pond frogs (1.3% for cyt b; 2.9% for control region). Analysis of genetic distances and phylogenetic trees based on both cytochrome b and control region sequences indicate that the Korean gold-spotted pond frog are genetically differentiated from those in China.

Local government with abundant natural resources should consider the nature conservation oriented planning process for the sustainable development. With this regard, the aim of this study is to provide a substantial methodology to support the decision-making process to designate the conservation areas. The objectives of the proposed methodology is to conserve natural resources in the local government's territory through quantitatively assessing the values of the natural resources based on various ecological factors such as topography, flora and fauna. In order to test the usability of the method, Gangneung City in Kangwon-Do is selected considering the latest data availability. Based on the assessment process land use of the subjected city could be categorized into 4 levels of conservative area, conservative level 1 area, conservative level 2 area, and conservative level 3 area. Among them, conservative area and conservative level 1 area could be combined as natural resources conservation area and the others could be regarded as buffer and transitional area. Especially conservation area is surrounded by conservation level 2 area. Conclusively, the GIS methods adopted in this could be the efficient illustrative tool to assess the local natural resource values with the central government established nature-environmental information systems.

A novel extraction method of high frequency small-signal model parameters for MOSFETS is proposed. From S-parameter measurement, this technique accurately extracts the model parameters including the charge conservation capacitance parameters. To consider charge conservation, nonreciprocal capacitance is considered. The modeled parameters fit the measurements very well without any optimization.

In museums, exhibition content focuses mostly on cultural heritage's historical values and functions, but doing so tends to limit visitors' interest and immersion. To counter this limitation, the study developed an experiential media art exhibition fusing bronze mirrors' traditional production technology and modern conservation science. First, for the exhibition system, scientific cultural heritage contents were projected on the three-dimensional (3D) printed bronze mirror through interactions between motion recognition digital information display (DID) and the projector. Then, a scenario of 17 missions in four stages (production process, corrosion mechanism, scientific analysis and diagnosis, and conservation treatment and restoration) was prepared according to the temporal spectrum. Additionally, various media art effects and interaction technologies were developed, so visitors could understand and become immersed in bronze mirrors' scientific content. A user test was evaluated through the living lab, reflecting generally high levels of satisfaction (90.2 points). Qualitative evaluation was generally positive, with comments such as "easy to understand and useful as the esoteric science exhibition was combined with media art" (16.7%), "wonderful and interesting" (11.7%), and "firsthand experience was good" (9.2%). By combining an esoteric science exhibition centered on principles and theories with visual media art and by developing an immersive directing method to provide high-level exhibition technology, the exhibition induced visitors' active participation. This exhibition's content can become an important platform for expanding universal museum exhibitions on archaeology, history, and art into conservation science.

This study investigated and analyzed the landscape conservation activity promotion process targeting the 'Alassiasdeuli Community Farming Association Corporation', which is carrying out continuous rural landscape conservation activities led by local residents in the area of Yeohang Mountain, Yeohang-myeon, Haman-gun, Gyeongsangnam-do. Through this, the factors necessary to promote rural landscape conservation activities led by residents were identified, and implications necessary for rural landscape conservation activities led by residents were derived. The first factor that allowed Alassiasdeuli to pursue resident-led rural landscape conservation activities was the fact that an economically stable foundation was established before pursuing conservation activities. Rural landscape conservation activities are carried out based on continuous agricultural activities, and agriculture is closely related to the economic aspect. Accordingly, Alassiasdeuli had a small but regular income from the package business, and was able to carry out various rural landscape conservation activities based on this. Second, within the community, a sense of purpose for rural landscape conservation was shared as a common value. It started with common values that were in line with rural landscape conservation, such as an economic community based on agriculture, indigenous seed conservation, and eco-friendly agriculture, and later, awareness of traditional agriculture and rural landscape conservation was gradually established through members' continued empowerment and related experiences. It has been done. Third, various connections and cooperative relationships were established with residents, related organizations, and administration. We established cooperative relationships by recruiting local organizations and residents as active participants beyond program participation, and exchanged information and expanded the scope of activities by establishing networks with organizations such as the 'Gyeongnam Darang-Non Network'. In addition, through connection with administration, we experienced various projects and ensured the sustainability of activities through support. Fourth, there was a keyman who could organize activities and control the scale of support projects, taking into account the awareness and capabilities of members. In particular, it is thought that this was possible because the Secretary General was based on building a relationship of trust with residents before Alassiasdeuli was formed. Therefore, in order for resident-led rural landscape conservation activities to be continuously carried out, an organization must be formed centered on farmers, and the economic sustainability of the organization, sharing of common values, and trust relationships among members are the basis, and the Sustainable activities can be promoted through various cooperative relationships between residents, organizations, and administration.
