Urban space expansion is an important symbol of the urbanization process and has always been an important topic in urban studies. In addition, for sustainable city management, it is important to identify factors that can influence, such as the driving force and direction of urban space expansion, from the stage of establishing an urban development plan. To understand these factors, by observing the expansion process of a specific city, it is possible to sufficiently observe how the urban spatial dimension changes. Through a series of processes, the spatial growth characteristics of the city are analyzed, and the influence and results of important factors are analyzed. For this purpose, this paper examines the changes in the city's outer boundary and land use structure through monitoring data on urban areas of 14 cities in Hunan Province, China from 2000 to 2016. Temporal and spatial regularity according to the urban space expansion of these cities were analyzed, and a preliminary assessment was made on whether the urban space expansion is coordinated with the urban population growth. The assessment result showed: (1) The urban space of most cities has been extended rapidly in 2000-2015 however, the rate and the intensity of urban space expanding has been declining. (2) The construction of the industrial park is the core driving force of the urban space expanding, and the change of the urban space structure is manifested as enclave city expansion because that the industrial park is usually far away from the city center. (3) The population agglomeration is another driving force of the urban space expanding. At this time, the urban space expanding is like boundary extension. (4) Except Changsha city, all of the cities has a high urbanization-area-growth elastic coefficient. It means that most of the cities should enhance the land use degree.

The main goal of this research was to understand housing environment as well as the living behaviors of Korean people who reside in foreign countries. This study includes examination of dwelling units, especially focusing on dwelling behaviors by space types, arrangement and use of the space, and the according residence patterns of the Koreans in the United States. Focus group interview method and survey method were conducted; photography were taken as a visual evidence; and results were analyzed by researchers. This study strongly indicates that most of Koreans try to keep their own way of living in foreign cultures and rather readjust the housing spaces and living patterns to their own culture. The results from this study have limitations in generalizing all Korean families living in foreign cultures, because a convenience sample was used. Although studies of Korean families in Columbia, MO may not provide information that can be generalized to the entire population of Koreans overseas, we expect that this study provides useful insight in understanding and estimating the future trends in residential planning for Koreans.

According to "The regulations regarding the residential construction standards", residents' common spaces are restricted by the standards on building facilities. In a typical apartment complex, residents' communal facilities are represented by a children's playground, a elderly social station, and a management office. However, these residents' communal facilities do not reflect residents' composition characteristics. Multidisciplinary research and experimentation to enable the community of housing complex are being actively conducted. In these situation, we observed institutional improvement about installing standard of community space, and analysed the tendency. The purpose of this study is to propose practical institutions to review the institutional improvement. We conducted a case study where was renovated the community space according to the new standard. As a results, the installing standard of the community space has changed in the direction to increase the autonomy of resident. These results raise the practical performance of the community space, and it has the effect of increasing the satisfaction of the residential environment. The results of this study suggest an alternative to the institutional aspects and planning aspects for community activation in housing complex.

The purpose of this study is to explore ways to efficiently capture the opinions of students who are main users in the planning, planning and design of school facilities. There are many criteria for determining good schools, but in this study, the main purpose of this study was to set up the main users as students, and to analyze the differences between the network and the actual spatial structure (network) created by the hope of students' use of school space, and the direction to overcome the differences. After surveying students' opinions about their satisfaction with school space and their desire to use school space by limiting the survey target to middle and high schools in Seoul, the 'social-space network analysis' was recently established in the social science field. As a result, it was found that the proximity of space and space desired by students in the school varied greatly depending on the geographical conditions, school districts, and the status of the current facilities, and the direction of improvement specialized for each school was found.

By analyzing the use of outdoor space in apartment complex and finding empirical proof which is concrete and systemic, this study focuses on the relationship between residents' daily lives and physical space. This study tries to find out the types and characteristics of outdoor space which causes the occurrence of residents' use in High-Rise apartment housing Estates, and analyzes the residents' usage pattern of outdoor space in eight different apartment complexes which were builted since 2004. After analyzing the usage pattern of outdoor space, the usage of playground was ranked highest and playing, talking, exercising, resting was in order. Especially it was found that the usage inside semi-public space where passing is abundant increases.

The purpose of this study is to investigate the use of Pilotis space in the elementary school and its problems and to explore some improvement scheme. The subjects of this research include the elementary schools in Deajeon, Chungju city which have been established since 1990 when the pilotis first introduced. It would be the effect of the decrease of site area and the increase of total floor area of elementary school. In this situation, this study aimed to figure out the characteristics of pilotis according to their types- Entrance type, Courtyard link type, Hybrid type- throughout the questionnaire, interview, and document analysis. The investigative situation was performed by employing a sample survey of 9 schools whose types were different from each other. The sample survey compared and evaluated scale, location, functions of Pilotis, the physical elements of types, connections with surrounding circumstances and the use under each condition. This study found that the use of pilotis at the elementary schools was inclined to the user, the teachers usually use pilotis only for passage, while the students use it in many ways according to the individual property. Pilotis space represent the differences in satisfaction and utility according to its type. To improve the relationship of users at the pilotis space, Courtyard link type is to be suggested and also it needs enough area as possible. In this way the pilotis type of elementary school gives great effect to the quality and function for better usage of this space.

Maintenance open spaces and community development in large scale housing development is one of the most important issues. We(UDC) established a resident participation activity for maintenance and use open space with community development in Hachioji New Town from 1997. The purpose of this study is to establish resident participation activities for maintenance and use open space with community development in Hajichioji New Town, and to clarify the characteristics and to on sider about efficiency of the activity. We established Minamino Shizen-Juku as a methodology for maintenance and use open spaces at the same time Hachioji New Town was opened in 1997. The activity has continued by now in 2001. We conducted questionnaire survey to make sure efficiency and characteristics of the activity past three years. Minamino Shizen-Juku (nature friendly lessons) is a resident participation activity in Hachioji New Town. It was established in 1997 as soon as the new town was opened, this year is fifth since it was started. It has three objects. 1)Maintenance and use woody environment, 2) Community development, 3) Continuation and renewal native culture. And it has general course, three special courses and one extra course were established in the activity. 1) General course is an activity participated all of member. It's included farming experience in the native field and seasonal events. 2) Rice growing and woods maintenance course is rice growing and wild wood maintenance in the park as a series of annual farming activities. 3) Benefaction from farm course is started from planting spring vegetable at Mizukoshi(Leader of Minamino Shezen-Juku)'s field. There is the number of participant limit because of the area of the field. 4) Watching nature course is watching seasonal wild flowers, trees, animals and plants to know about native nature. 5) Extra program is programmed to know about native history and tradition. It's planned including participant's ideas. Not member can participate in this course too.

In this talk, we will give an overview of the small telescope network project in Korea. The small telescope network is a project in planning that would gather 0.4m-1.0m telescopes in Korea together for a common use in research and education, and the project is being led by the Optical/IR Astronomy Division of KAS. Even in the era of giant telescopes, small telescopes are still competitive for various research topics that require rapid response or long-term, steady monitoring. There are quite a few small telescopes in Korea, but the research use of these telescope has been very limited. By organizing these telescopes together, the small telescope network hopes to bring these telescopes in full operation and offer Korean astronomers competitive observational resources. In this talk, we will outline the project, describe potential resources, and several science cases such as multi-messenger astronomy, supernovae, and AGN. We will also introduce how this project might be run, with the expected operation of the small network starting at 2020.

Korea Astronomy and Space Science Institute researchers have installed and operated magnetometers at Bohyunsan Observatory to measure the Earth's magnetic field variations in South Korea. In 2007, we installed a fluxgate magnetometer (RFP-523C) to measure H, D, and Z components of the geomagnetic field. In addition, in 2009, we installed a Overhauser proton sensor to measure the absolute total magnetic field F and a three-axis magneto-impedance sensor for spectrum analysis. Currently three types of magnetometer data have been accumulated. In this paper, we use the H, D, Z components of fluxgate magnetometer data to investigate the characteristics of mid-latitude geomagnetic field variation. To remove the temporary changes in Earth's geomagnetic filed by space weather, we use the international quiet days' data only. In other words, we performed a superposed epoch analysis using five days per each month during 2008-2011. We find that daily variations of H, D, and Z shows similar tendency compared to previous results using all days. That is, H, D, Z all three components' quiet intervals terminate near the sunrise and shows maximum 2-3 hours after the culmination and the quiet interval start from near the sunset. Seasonal variations show similar dependences to the Sun. As it becomes hot season, the geomagnetic field variation's amplitude becomes large and the quiet interval becomes shortened. It is well-known that these variations are effects of Sq current system in the Earth's atmosphere. We confirm that the typical mid-latitude geomagnetic field variations due to the Sq current system by excluding all possible association with the space weather.
