  • Idleness in rural areas is a very important issue with regard to national land space management. Previous studies have been conducted separately in terms of population housing and farmland. So, an integrated analysis considering population housing and farmland is required for rural spatial management. In this study, vulnerability indices were developed and spatial distribution of the vulnerable areas was analyzed by evaluating regional vulnerability on population, housing, and farmland. In addition, plans for rural space management plan were proposed considering the population hollowing out and the idle farmland. The results of this study would be helpful in preparing policies that take into account the vulnerability of idleness in rural areas.

  • We analyzed diurnal variations in the surface air temperature using the high density urban climate observation network of Daegu in summer, 2013. We compared the time elements, which are characterized by the diurnal variation of surface air temperature. The warming and cooling rates in rural areas are faster than in urban areas. It is mainly due to the difference of surface heat capacity. In addition, local wind circulation also affects the discrepancy of thermal spatiotemporal distribution in Daegu. Namely, the valley and mountain breezes affect diurnal variation of horizontal distribution of air temperature. During daytimes, the air(valley breeze) flows up from urban located at lowlands to higher altitudes of rural areas. The temperature of valley breeze rises gradually as it flows from lowland to upland. Hence the difference of air temperature decreases between urban and rural areas. At nighttime, the mountains cool more rapidly than do low-lying areas, so the air(mountain breeze) becomes denser and sinks toward the valleys(lowlands). As the result, the air temperature becomes lower in rural areas than in urban areas.

  • Purpose: The small-scale environmental impact assessment conducted during the development project stage has focused on the preservation of the natural environment centered on non-urban areas, due to the nature of urbanization, health problems for citizens of high-density urban areas have a limitation in that they are relatively neglected. In the case of strategic environmental impact assessment and environmental impact assessment in urban areas, there is no basis for evaluation in urban areas because there are exceptions to be excluded from the target projects or there are no target project regulations for buildings. Therefore, in this research, we examined the problems with the target project such as the current environmental impact assessment, and tried to establish a system improvement plan that can solve them. Research design, data and methodology: After reviewing the current environmental impact assessment-related laws (including enforcement ordinances) and national land planning laws (including enforcement ordinances), exceptions such as environmental impact assessment in urban areas were identified and problems were identified. Based on this, an amendment to the Enforcement Decree was proposed to provide institutional support for the expansion of target projects such as environmental impact assessment in urban areas. Results and Conclusions: Through this research, it is expected that the projects subject to environmental impact assessment on development projects in urban areas directly related to the health of the people will be expanded, and the net function of the environmental impact assessment system will be maximized.

  • As that experienced in other developing countries, Mongolia has already faced multilateral side issues for two decades due to economic growth that created Ger areas or internationally 'Slum', public housing and living conditions for low-income citizens, on the basis of rapid migration from rural areas to urban. Ger areas appear to be the main cause of environmental pollution problems and impending comfortable living conditions of the city's residents by covering more than half area of Ulaanbaatar city. Also, the spread of the Ger areas has many side issues such as prevention of urban development and unaesthetic. Most inhabitants of the areas are on low-incomes, and living in the detached houses or felt yurts (Ger) usually build within a low budget, by themselves or unprofessional people, and by using materials of poor quality. Therefore, Ger areas are an inevitable issue that requires effective, proper and immediate housing policy coordination under the government and even the housing market. Unfortunately housing policies, laws, and projects adopted by Mongolian government have shown inefficient results. The government housing policies, unlike other developing countries did not target low-income households' housing which is the priority issue for two decades. But only in 2014, the Long-term housing policy with the strategy for affordable housing initiated the housing policy for low-income households. This policy has five main broad directions such as redevelopment of Ger area, the land readjustment, public rental housing, new settlements and new city and reconstruction for old apartments, which are rather general and would require tremendous financial resources if each of the directions is implemented simultaneously without prioritization. Therefore this research aims to suggest the efficient and adequate housing policy direction for the low-income households in Ger area based on achievement of other developing countries' strategies, performances and generic characteristic with explanatory models. Also, this research adopts a literature analysis method that uses various research reports, related papers in domestic and international journals, and theses by experts, researchers, public institutions, and agencies.

  • This study was conducted to evaluate the quality variation of Lithospermum radix on the pigment contents and antioxidant activities according to different growth stages and areas of cultivation. Acetylshikonin contents showed the tendency to decrease gradually from the middle of July (0.28%) to the end of August (0.05%) and then the content was increased again to the end of October (0.25%). Shikonin content was detected as small amount of about 0.009% during the period. The weight of plants was increased from the end of September to the end of October and showed the highest value as 19.8 g on October 25. ROS scavenging activity was the highest in the early of October as $IC_{50}$ value of 0.11 ${\mu}g/mL$. Lithospermum radix of September showed lower ROS scavenging activities than those of other growth stages as $IC_{50}$ value of 1.02 and 0.49 ${\mu}g/mL$ on September 9 and September 27, respectively. Among 17 areas cultivated Lithospermum radix, 10 areas (59%) showed 0.05-0.10% of acetylshikonin contents and 3 areas (18%) were measured to contain 0.16-0.26% of acetylshikonin.

  • We have grown well-aligned carbon nanotube arrays on the selective areas by plasma enhanced chemical vapor deposition at the substrate temperature of $580\;^{\circ}C$. The selective areas for CNTs growth can be defined by photo lithography technology. The CNTs are uniformly grown on the areas regardless of island diameters. Electron emission currents were measured in a vacuum with a diode structure at room temperature. Uniform electron emission currents were achieved with $40\;{\mu}m$ island spacing with $5{\mu}m$ island diameter.

  • This paper proposes empirical research areas and a curriculum model that outlines the core concepts of major research topic and educational programs of family business. The purpose of this study was two fold: First, to develop the conceptual and empirical research model of family business. For this purpose, this study examined five conceptual issues - ethical, theoretical, management, historical, environmental - in the development of family business research areas. Based on these five conceptual issues, this study developed an empirical research model of family business. Second was to develop the curriculum model of family business at the university level. This curriculum was developed in terms on the family system. business system, and ownership system of family business. This study will be useful in developing more professional curriculum and educational programs to help educator and professional advisors assist family businesses.
