The purpose of this study is to seek for a direction of child-care development through the basic concepts of home economics which have taken charge of much parts of the studies in child-care in the early years. When the problem of child-care is studied in view of the developmental process or the basic concepts of home economics, it is summed up as follows; First, on the basis of human ecological approach, when we study child-care, it needs to emphasize the mutual relationship between the macro-environment in connection with home and child-care. The study of child-care have to find out the relationship between the micro-environment in connection with children and the macro-environment in connection with home. And on the basis of this study, we must endeavor to build up the desirable environment of child-care. Second, on the basis of the concept of Institutional household, we mud be concerned about the developmental stages of young children, and emphasize 'the principle of love and care'. This means that the institution of child-care must be considered as a place which enlarges the merits of home and complements the defects of home through the strengthener of the function of home. Third, on the basis of healthy family, child-care service must support and complement the function of bringing of home in view of 'total healthiness of home'. Child-care service must be offered to be able to be chosen according to the total conditions of family such as the employment of mother, the family life cycle, the life style, the socioeconomic status of family.

The purpose of this research is to establish a green space conservation grade for sustainable urban development of Taegu metropolitan city using GIS and RS methods, together with the valuation items of green spaces centered around ecological, useful, and socio-cultural factors. The results of this study are as follows: 1. According to the ecological factor, the first grade is $81.4km^2$ and then Kachag-myun, Dong-gu in order, have needs of sustaining conservation policy of urban environment improvement and protection of the wild habitats. 2. According to the usefulness of urban parks, the first and second grade which is over 150 $persons/km^2$ in population density of the catchment areas, were Talsung park, Sinam park, Yongsan park and etc., the areas of those parks consists of 0.7% of the whole urban parks. 3. According to the socio-cultural factor, the first grade is located in urban natural parks, and the second grade is which are composed of Green Belt and agriculture in Talsung-gun. 4. Analyzing these results synthetically, the first grade conservation is 18%, as the forest in the upper zone of Mt. Palgongsan, Mt. Bisul, and Mt. Daeduck, these regions needed to preserve absolutely. This research is a basic step to show the methodology for all-round evaluation of green space using GIS and RS. Hereafter, it is necessary to consider general evaluation index of green spaces, and to consider the quantitative and qualitative aspect.

We've compared and conceptually evaluated the newly emerging concept of nature-based solutions (NbS's), in the aspect of water management, and existing similar solutions of different naming, all of which are based on ecosystem functions. In this study, it is found that NbS's seem significant and meaningful both educationally and understandably in the aspect that it can comprehensively cover and include the existing methodologies and solutions using the functions of natural ecosystem to socio-environmental challenges. It, however, seems not quite different from the broad-meaning of green infra, including Eco-DRR, in terms of the approaching methodologies in water management. The conceptual and spatial hierarchy of each practice in water management considered in this study can be expressed in the narrowing order of NbS-(EE)-BGI-(CRT)-GI-LID. Last, the term LID, which is the best management practice for storm water management in the development project, can be replaced with the term GI for clarification and less confusion both in academia and practice.

Residents of urban area like to be near rural animals during their daily life, so it is important conserve the suburban Yato landscape in Japan. This study targets the species of frogs that are commonly found in Yato paddies. It is necessary to various frogs inhabiting in Yato, because frogs are popular among Japanese, who as children enjoy capturing tadpoles and frogs. Its purpose is to clarify how that composition of frog species changes when the functionality of a frog habitat is diminished by urbanization. The survey, conducted in the Eastern Kanagawa area in central Japan, determined the distribution of each species of frog in grid cells measuring 0.5-$\textrm{km}^2$. It hsows wide distributing species (Hyla japonica; they always inhabit in all paddies), the middle range distributing species (Rhacophorus schlegelii and Rana porosa p.), the limited range distributing species (R. rugosa; they are most critical species, sine they are recognized only two cells), and so on. Correspondence analysis based on the frog species composition in each cell was performed to ascertain the adaptability of each species to various paddy field conditions. The results allowed us to classify cells into four groups according to the composition of the inhabiting species. And we recognized that the process by which frogs disappear occurs in reaction to either of two patterns of change. As paddy fields are improved by farmland consolidation, R. rugosa, R. ornativentris, R. japonica, and Bufo. japonica f. decline rapidly. In plateau areas, a smore andmore paddies are converted into strong, well-drained fields, only H. japonica and R. porosa p. remain. But in hilly areasd, the species composition becomes only H. japonica and R. schlegelii. Finally, we discuss the concept of ecological urban design in the context of the conservation of frog species in Yato paddies.

This study was carried out to provide guidance to environmental policy makers when deciding which assessment fields (biotic, abiotic, qualitative, functional) should have priority for ecological preservation and to develop an objective and scientific methodology by introducing the engineering concept of the fuzzy integral. The grant of weights was used the eigenvalues calculated by factor analysis, and the converted values of indicators were obtained in multiplying the arithmetic values and eigenvalues. The results of the appropriateness and reliability of assessment fields were examined over 0.6, and the results showed that the design of questionnaire presented no great problems. When the fuzzy integral was calculated to determine the rankings at ${\lambda}$=1, 2, 3, 4, 5, respectively, they were 0.646, 0.630, 0.943, 1.423, and 1.167 for the biotic field, 1.298, 1.400, 0.901, 0.580, and 1.456 for the abiotic field, 0.714, 0.674, 0.346, 0.674, and 1.610 in the qualitative field and 1.000, 0.973, 0.943, 1.024, and 1.008 in the functional field. The sensitivity to ${\lambda}$ value showed that ${\lambda}=4$ was the most suitable. In comparison with ${\lambda}=0$ (the arithmetic mean), the range of change was narrow. Because the range for ${\lambda}=4$ was narrower than my other values, ${\lambda}=4$ was sure to be available in ranking-decision. The fuzzy integral is expected to be a method for analyzing and filtering human thoughts. In the future, in order to overcome linguistic uncertainty and subjectivity, other fuzzy integral models including Sugeno's method, AHP, and so forth should be used.

In general, industrial production involves large amounts of harmful by-product, causing serious pollution and ecological risk. Eco-efficiency, which indicates how efficient the economic activity is by considering both the environmental risks and economic performance, is a new concept for economic sustainability analysis and quantitative ecological risk analysis. Data envelopment analysis (DEA) has been widely used to examine eco-efficiency in recent years. Whereas traditional DEA models such as CCR and BCC model neglect undesirable outputs, this paper adopts a stochastic undesirable-output DEA model to measure the eco-efficiency of each province of China and Korea. The results indicate that whereas the eco-efficiency of the eastern region was the highest, that of the western region was the lowest. The reason may come from the negative external dis-economies of environment. And thus the governmental efforts for outreach on the underdeveloped regions should be promoted.

In Germany has a long history of ecological restoration and restoration management. At the beginning of the 1990s, the "Erfolgskontrolle" was used as an evaluation program after the restoration project and many exchanges of views took place. It is the time, in Korea, there is a need for a comprehensive evaluation program after the restoration project, as there is no evaluation method yet. At this time it may be the "Erfolgskontrolle" in Germany as a practical model for the Korean restoration management program. The purpose of this study is to identify the concept and character of the "Erfolgskontrolle" and to demonstrate the implication and potential of application, through the analysis of the implementation example of the revaluation of river revitalization. To achieve the goal was carried out theoretical and 3 exemplary revitalization research cases. And it was endeavored to deliver the German way of acting and the basic idea to Korea. For the restoration, the "precautionary principle" should be considered first, the upper legal regulation should not be violated. In order to apply "Erfolgskontrolle" in practice, the goal formulation should be clear and systematically evaluated. And through the collection of typified cases, the comprehensive and unified theory should be established, it is possible, thus the qualitative assessment of the restoration project.

Integrated pest management system in Korean apple has significantly advanced for last few decades. However harmful effects of pesticides threats the ecosystem services of natural enemies and pollinators. Apple require cross-pollination and Insect pollination with diversity and abundance is one of the keys to profitable apple production in quantity and quality as well. Thus crop protection tools are to be administered in harmony to meet the pest suppression and protection of beneficial organisms such as natural enemies and pollinators. Adding onto the established IPM system, integrated pollinator-pest management (IPPM) concept is proposed as the future direction of apple IPM. For this, ecological enginnering of creating habitats for pollinators, landscape management and agroecosytem diversification as well as selective soft pesticide uses on time guided by pest monitoring and phenologyand targeted delivery are further proposed. Recent shift of agroecosystem from climate change and new pest outbreaks require new paradigm of pest management for sustainable agricultural production.

This paper deals with the meaning of seeing in John Ruskin's aesthetic theory. For Ruskin, seeing is the essential key to define moral insight. To consider the relationship between the education of sight and the delight from experience of seeing in nature within Ruskin's moral thought, I analyse Ruskin's various lectures and texts, including Modern Painters, The Story of Halcyon, Of the Science of Light, Proserpina, and Praeterita. The first section of the body investigates the relations among pleasure, thought, sight which compose Ruskin's moral ecology, and then the second section traces the theoretical logic formed the concept of seeing as moral perception of human being. The third section demonstrates correspondence between aesthetic experience of pleasure and the way of seeing as an education for the mystery of Nature and God. After these theoretical processes, this paper finally insists that seeing is the factor of formation of an ecological sensibility corresponding with development of moral perception generated within the hierarchical structure of human-nature-god.

Dental caries is a multifactorial disease influenced by interactions between teeth, biofilm, dietary factors, and various biological, behavioral, sociocultural, and genetic factors. Recent research has shown that dental caries results from dysbiosis, an imbalance in the oral microbial community, shifting the concept from an infectious disease to a non-communicable disease (NCD). Dental caries shares similarities with other chronic NCDs such as cardiovascular diseases and diabetes, as they all relate to dietary intake, lifestyle habits, and environmental factors. Considering the high prevalence of dental caries and its impact on people's health and quality of life, it is important to understand dental caries as an NCD and develop effective oral health management strategies. Ecological prevention methods and efficient public health policies should be provided to reduce risk factors associated with dental caries.
