Understanding the need for temperature regulation, behavior, and ecology of hibernating bats provides the possibility of conservation and management for target species. Our objective in this study was to improve understanding of the population trend and ecological requirement in Myotis formosus population in South Korea. From 2007 to 2016, total of 58 hibernacula for Myotis formosus were found across the country. Of the 58 hibernating sites of Myotis formosus, 86% (n=49) were abandoned mines and 14% (n=8) were natural caves. During the survey period, 28 (5%) bats of total 570 bats were observed in natural caves (n=8) and 542 (95%) bats were observed in abandoned mines (n=49). The internal environments of hibernacula of M. formosus were highly stable despite dramatic variation in the external environment. Specifically, we examined the population trend of the endangered bat Myotis formosus in South Korea by long-term monitoring for hibernation sites. The population trend of endangered species M. formosus showed a marked stable in hibernating population. Our results indicate that a tightly collected long-term data set may help to establish the initial approximation of population trends and manage to threats for the endangered bat species.
The purpose of this study is to investigate the differences among mother's feeling expression, children's self-regulation, and children's peer competency by socio-demographic background and provide a basic material to develop the parents' education for mother's promosing emotional environment to help development of children by understanding the correlation among mother's feeling expression children's self-regulation, and children's peer competency. The research objects were 361 of 4 to 6-year-old children and their mothers. The tool adapted by Woo Sookyong(2002) was used for Mother's emotional expressivity, and the tool of Lee Jeongran(2003) for the of self regulation and the tool of park Joohee and Lee Eunhae for the children's peer competency. Data analysis was performed with population, percentage, t-test, Cronbach $\alpha$, F-test, and co-relation of LSD posteriori test. The summary of this study are as follows; First, the more negative expressivity was shown as mother's academic career was higher and the more positive one was appeared as family income was greater according to the background of socio-demography. Female children showed the higher self-regulation, and the self-decision and action control were greater as their age was higher. Children's peer competency was higher as they were social and friendly personality. Second, there was the strong relationship among the mother's feeling expressivity, children's self-regulation and peer competency one. Mother's positive expressivity had the relationship with children's self-regulation and peer competency one while weak expressivity had it with self-decision, regulation and children's peer competency. But the strong negative heartstrings' expressivity was an improper co-relation with action control and no relation with similar age competent ability. A definitive relation existed between all low level area except the emotion of self-regulation and children's peer competency. Form the above study, it was Known that there was the relationship among the mother's feeling expressivity, children's self-regulation and peer competency. In particular, there was strong relationship between positive and weak positive expressivity, and children's self-regulation and peer competency. These results could be reflected to parents' heartstrings education by knowing the impact of a positive emotional expressivity and weak-negative one.
The increase rate of total population slows down and the ratio of the elderly population & single-household in our country is growing rapidly. Korean's housing penetration has already exceeded 100%. So people focus on the qualitative aspects of housing, namely housing welfare than the quantitative supply of housing The purpose of the study proposes the desirable direction for housing welfare policy based on the housing welfare regulations. The data for the analysis was collected through the regulations of 8 cities and 9 provinces. So housing welfare contents like housing welfare business, housing welfare center, etc. were extracted from 4 Housing Welfare Support Regulations, 5 Housing Basic Regulations and 8 Housing Regulations. The results were as follows: To stabilize housing and improve housing, the contents of housing welfare contained in related ordinance are still insufficient. Continue to be effective and housing welfare work, it shall be presented in detail in the regulations with respect to the financing plan. To those who need the housing welfare will have to be built an effective delivery system that can be delivered in a timely manner. For housing welfare for the elderly, housing welfare business information is detailed and broken down, it should be codified.

The development of routine techniques for the isolation and in vitro maintenance of conducting airway epithelial cells in a differentiated state provides an ideal model to study the factors involved in the regulation of the expression of mucocilicary differentiation. Several key factors and conditions have been identified. These factors and conditions include the use of biphasic culture technique to achieve mucociliary differentiation and the use of such stimulators, the thickness of collagen gel substratum, the calcium level, and vitamin A, and such inhibitors, the growth factors EGF and insulin, and steroid hormones, for mucous cell differentiation. Using the defined culture medium, the life cycle of the mucous cell population in vitro was investigated. It was demonstrated that the majority of the mucous cell population in primary cultures is not involved in DNA replication. However, the mucous cell type is capable of self-renewal in culture and this reproduction is vitamin A dependent. furthermore, differentiation from non-mucous cell type to mucous cell type can be demonstrated by adding back a positive regulator such as vitamin A to the “starved” culture. Cell kinetics data suggest that vitamin A-dependent mucous cell differentiation in culture is a DNA replication-independent process and the process is inhibited by TGF-${\beta}$1.

The renewed global interest in nuclear power has arisen from the need to reduce greenhouse gas emissions and to provide sufficient electricity for a growing global population. Many countries with nuclear power plants (NPPs) are still implementing license extensions of 10~20 years, and even consideration is being given to the concept of life-beyond-60, a further period of license extension from 60 to 80 years. To solve the materials aging problem is integral to its success. A foundation for effective aging management of nuclear power plants is that aging is properly taken into account at each stage of a plant's lifetime, i.e. in design, manufacture, construction and operation including long term operation and decommissioning. To evaluate the plant aging phenomena, a lot of background information such as materials and environment of the parts of the reactor and plant systems is needed by the experts. Information on degradation mechanisms is also used. In this paper, a regulation on the integrated materials aging management for nuclear facilities is proposed. The proposed regulation identifies key elements of effective aging management for nuclear power plants and provides the requirements on aging management for nuclear facilities throughout all stages of the lifetime of the plant.
The purpose of this paper is to perform empirical studies on the impact of pollution intensity on international competitiveness using 1993 and 1998 data, and to estimate the change in environmental regulation level faced by the firms during 1993~1998. Collecting relevant data and providing them for further studies in the area are another purposes of the paper. The first method is the regression of various indices of international competitiveness on factor costs, such as labor, capital, R&D and pollution abatement costs. Goal of the regression analysis is to estimate the scarcity and comparative advantage effect of each production factor, especially environmental resource. Regression results show that those industries which employ more environmental resource have higher comparative advantage in both years, which implies that Korean firms are endowed with abundant environmental resource compared to other countries. The second method is to compute the relative scarcity indices(HOVL indices) of production factors, proposed by Leamer based on Vanek's generalized Hecksher-Ohlin Theorem. This method estimates the relative scarcity of production factors by computing factor costs embodied in import and export of commodities. This method shows similar results as the regression method; i.e., trade pattern of production factors implies that the manufacturing sector in Korea is endowed with abundant environmental resource compared to other countries. Considering population density, water resource endowment, intensity of economic activity per unit area and current air and water pollution levels, it is evident that Korea is never endowed with abundant environmental resource compared to other countries. Then the abundance of environmental resource revealed by the trade patterns of commodities and production factors implies that Korea's environmental regulation level is excessively generous compared to environmental capacity, and that this increased the environmental resource endowment supplied to firms and thus distorted the inter-industry comparative advantages. Both regression and HOVL methods, on the other hand, show that overall environmental regulation level faced by the firms has been strengthened during 1993~1998.
Science, technology and innovation (STI) has expanded the activity of actors from the traditional physical territory to the cyberspace. Data-driven platform services and markets advance new discussions on cross-border cooperation and cyber security, as well as discourse on sovereignty in cyberspace. These changes are also affecting the hegemony competition between the US and China. In particular, competition for aid to developing countries that are located along major resource transportation routes, such as natural gas and deep sea resources, is fierce. ASEAN is not only a geopolitical military and security point where the US and China powers collide, but its population of 600 million has great potential for the development of the digital economy due to its data resources. In this regard, this article aims to connect the discourse of liberalism and authoritarianism with data regulation and cybersecurity in international development cooperation, and derive implications for ASEAN integration through this. This study has significance as a convergence study that links international political issues related to big data in terms of global governance.
The present study was undertaken to determine the effect of tensile force on DNA and protein biosynthesis in bone cells, and to identify the cell type(s) which primarily respond to external physical force among the heterogenous bone cell populations. As a prerequisite for this study, two bone cell populations which retain fibroblastic and osteoblastic feature were isolated from fetal rat calvaria with sequential enzyme digestion scheme. Tensile force was delivered to each bone cell population by two acrylic resin plates connected with a orthodontic expansion screw during culture period. Rate of DNA and protein synthesis in each bone cell population were assessed by the incorporated radioactivity of $[^3H]-thymidine$ into DNA and $[^3H]-proline$ into fraction of collagenase-digestible protein and noncollagenous protein, respectively. DNA synthesis of osteoblast-like calvarial cell populations was increased significantly by the application of tensile force for 24 hours. In contrast, no alteration in DNA synthesis of fibroblast-like populations could be observed in response to applied force. Tensile force induced the change in protein synthesis of bone cell populations with the same pattern. Total protein and collagen synthesis were increased whithin 24 hours in osteoblast-like populations, but not in fibroblast-like populations by tensile force application. These findings indicate that physical force can affect cellullar activity of the particular cell population, not all cell Populations residing in bone and osteoblasts respond more sensitively than fibroblasts. So osteoblasts can modulate the behavior of other bone cells including osteoclasts by producing several local regulating factors of bone metabolism. In this context, preferential responsiveness of osteoblasts to applied tensile force observed in this study suggests that osteoblasts may play an important role in regulation of physical force-induced remodelling process.
Tendency in ratio of biotope area of environmental impact assessment (EIA) according to population, location, project type, and total project area was analyzed by type of the projects. According to EIA, biotope area ratio is the ratio of the weighted biotope areas and total project area. biotope area is important to resident's health and quality of their life. Ministry of Environment recommends to meet the biotope area ratio standard presented by each project type. The analysis is based on 4 types of project, urban development, industrial comlpex deveopment, tourism development, and waste and sewerage treatment facility, and 55 data extracted from them. It is needed that new standard that the population is reflected, adjustment that region and frequency are considered, and regulation strengthening according to achievement of 'the minimum achievable goals' to improve biotope area policy. The research includes more data and improvements of specific system are needed as a further research.
