The purpose of this study is to identify the characteristics of the community design ordinance in Seoul as view of the community design activation and to seek improvement. The findings of this study are as followings; Most of the provisions of the ordinance, such as the concept of community design, the basic plan, and the contents of the project, are defined in a similar manner. From the establishment of the concept of community design, it is necessary to establish the regulations that reflect the actual situation and characteristics of the village. In addition to physical facilities improvement, the ordinance should include support for securing space at the core center, which plays an important role in revitalizing community design. Step-by-step approaches are needed to understand the residents at the beginning of the project, because there is not enough practical support related to resident capacity and community solidarity. As the importance of the competent residents increases, the support elements related to humanware areas should also be expanded. In particular, the supporting process and contents for the support system and program for the training of village leaders and the securing of professional manpower should be well established.
Sustainable development has been praised as important new planning paradigm. The concept is being increasingly used in planning processes to address environmental, social and economic sustainable development. The social sustainability is important as community in modern life. The purpose of this study is to find out the community elements of sustainable housing to make it better life in residential environment. The Methods are content analysis and experts survey. We execute the literature for method to find the importance and indicator of social sustainability. We execute the experts survey to find the adequacy of the classification criteria, the adequacy of the indicators and the adequacy of the classification system. The findings of this study are as following; the social sustainability is important to support the sustainable housing planning. The indicator of the social sustainability is deduced; 'Locality' are deduced 'Native support', 'History and culture' and 'Reflected the local characteristics'. 'Communality' are deduced 'Citizen participation', 'Social integration', 'Community space and facilities' and 'community activities and programs'. 'Organic' are deduced 'Employment', 'Self-sufficiency', 'Safety and convenience', 'Infrastructure and service' and 'Housing condition'.
A program of public facilities is essential in a resident's life, and such a programs affects the quality of life and community activation. The purpose of this study is to analyze the present condition of the program of public facilities and the residents' need of the program in Yanglim-Dong, Gwangju. In this study, a field survey and questionnaire survey are used for data collection. The results of this study are shown as follows: first, most of the public facilities' programs are composed of educational and welfare programs and programs for teenagers, young people and middle-aged people. Second, most of the residents prefer to have a program for culture and sport. Third, age according to program preference and in terms of educational relation program and cultural relation demand difference approaches. Fourth, most of the residents want to join one or two programs every weeks and prefer to participate during the afternoon and evening.
Abstract. The active fraction of the extract of Asiasari radix, the 60% methanol chromatographic fraction from the ethyl acetate layer (PPAR), was used to investigate the melanogenesis signal pathway in B16F10 melanoma cells. PPAR led to significantly decreased melanin synthesis and tyrosinase activity in a dose-dependent manner. PPAR also reduced the expression of melanogenesis-related proteins including microphthalmia-associated transcription factor (MITF), tyrosinase, and tyrosinase-related protein (TRP)s while down-regulating the expression of mRNA of MITF and tyrosinase. Melanogenesis-regulating signals, such as mitogen-activated protein kinase (MEK)/extracellular signalregulated kinase (ERK), phosphatidylinositol 3-kinase (PI3K)/Akt and p38 mitogen-activated protein kinase (MAPK) were evaluated, and ERK was activated by PPAR. The selective inhibitor of MEK/ERK, PD98059, abrogated all suppressive activities of PPAR on melanin biosynthesis, tyrosinase activation and expression of melanogenesis-related proteins. These results suggest that ERK activation by PPAR contributes to reduced melanin synthesis via ERK signal pathway-mediated suppression of MITF and its downstream signal pathway.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
