This study has taken the Myeongjidong island, which has experienced spatial change due to various reasons ranging from the Japanese colonial era until today, as an instance in order to comprehend macroscopic spatial change of the Nakdonggang Delta and the adaptation process of the locals in a microscopic point of view. Spatial change of the Myeongjidong has been confirmed by collecting maps such as the atlas of late period of Chosun published in 1910, topographic map, regional geography, city records, and by applying coordinates with geographic reference function of GIS program, then checking for time sequential space change of individual regions. Space change driven by the Japanese government-general of Korea, Gimhae Irrigation Association, and by national policy or planning brought about environmental and humanistic changes unlike ever before, and land usage, housing and industry of the region and the locals experienced various adaptation processes. Such processes were compiled through collection and comparison of literature, and supplementation from interview of the locals during field study. As for the research region, it ranged from the construction of Nakdonggang bank and Myeongji seawall of 1935, agricultural rural landscape formed after the area expansion project by Gimhae Irrigation Association in 1940, to landscape that are becoming mercantile and urban due to the developmental plans of national and local governments.

The purpose of this study is to investigate the effect of urban sprawl and their ramifications, i.e. segmentation and hierarchization on the spatial structure as well as populational composition, focusing on Daecheon - Village and Daecheoncheon - Network in Busan, and to examine not only the solidarity between constituents transcending the segmented spaces but also the internal values operating inside through the Daecheoncheon - Network. Due to the large - scale housing development in the 1980s to 1990s, Daecheon - Village has been transformed from a rural village to a town. In this process, the original single space became segmented into Daecheon - Village and apartment complex. This spatial segmentation divided the populational composition into old natives and young immigrants. However, the Daecheoncheon - Network created by solidarity between the bodies of two localities enabled the residents to resolve the urgent issues of localities, recognizing their own space of living not as segmented and hierarchic but as the communal site of life and one village where they will live together. Daecheoncheon-Network was the movement and network to connect natives and immigrants transcending the segmented space and went so far as to make a motive to create one community with the value of 'symbiosis.'

This study aimed to estimate and evaluate the thermal mitigation of the urban tree canopy on the summer outdoor environment by quantitative use of mean radiant temperature. This study applied the SOLWEIG model based $T_{mrt}$ comparison method by using both (1) urban tree canopy presence examples and (2) urban tree canopy absence examples as constructed from airborne LiDAR system based three-dimensional point cloud data. As a result, it was found that an urban tree canopy can provide a decrease in the entire domain averaged daily mean $T_{mrt}$ about $5^{\circ}C$ and that the difference can increase up to $33^{\circ}C$ depending both on sun position and site conditions. These results will enhance urban microclimate studies such as indices (e.g., wind speed, humidity, air temperature) and biometeorology (e.g., perceived temperature) and will be used to support forest based public green policy development.
The principal objective of this study was to assess the situation of foodservice facilities, utilities, and physical environment in the Chonbuk area. Self-administered questionnaires were collected from 252 nutrition teachers and school dietitians. Statistical data analysis was completed using the SPSS v. 11.5 program. The results were summarized as follows: Approximately 99.2% of the subjects were women 76.6% were married, over 87% were between the ages of 30 and 40(p<0.01) and 56.8% had more than 11 years of experience(p<0.001). Among the 252 school foodservice systems evaluated, 51.6% of the schools were located in urban areas and 48.0% were in rural areas(p<0.01). Approximately 68.0% of the schools prepared meals in the conventional way, and 32.3% prepared them in the commissary way(p<0.001). The number of employees at each institution was separated into the following categories: 1 to 3(37.7%), 4 to 6(27.8%), and 7 to 9(25.4%, p<0.01). Approximately 54.0% of schools had been running a school meal service for longer than 11 years(p<0.001). However, 67.5% of those facilities had not been remodeled since the initial implementation of foodservices. Approximately 94.0% of the school foodservice facilities were located on the first floor. 72.2% among them were constructed of reinforced concrete and 16.7% were prefabricated(p<0.001). As the result of our evaluation of related physical evidence and the atmosphere of the space, the average importance grade was $4.41{\pm}0.46$, and the average performance grade was $2.78{\pm}0.67$. Most nutrition teachers and school dietitians in elementary, middle, & high schools responded that the related physical evidence and the atmosphere of the space in school foodservice facilities were important, but the satisfaction level among the nutrition teachers and school dietitians was quite low. Therefore, it's important and necessary to analyze the opinions of the stakeholders in the foodservice industry prior to the remodeling of school foodservice facilities and utilities.

As large-scale housing sites are being developed rapidly in Sejong City, which was launched in 2012 for resolving the adverse effects of overconcentration in the capital area, promoting balanced development of the country, and reinforcing national competitiveness, changes in spatial structure are expected in the surrounding areas. For setting the directions of urban planning, it is essential to understand changes in spatial structure. This study purposed to measure changes in the spatial structure of neighboring areas resulting from the construction of Sejong City by approaching from the aspect of spatial interaction. In the analysis, we calculated population potential for future spatial interaction using the accessibility model, and interpreted quantitatively and qualitatively the outcomes of spatial interaction among neighboring areas before and after the construction of Sejong City using population potential as an indicator. According to the results of the analysis, the impact range of the population potential of the subject areas had been shrinking continuously since 1995, and in 2013 population potential dispersed as the population concentrated on and around Cheonan City. Although Sejong City, as a new area of population potential, was not found to play the role of a pivotal point for the surrounding areas, it is probably because the analysis was made just after people began to move to Sejong City. Accordingly, along with the effort of Sejong City to reach the planned population, it is necessary to keep monitoring changes in related factors and changes in the spatial structure of the surrounding cities resulting from the growth of population.

National surveys on the prevalence of intestinal parasitic infections have been carried out every 5-7 years since 1971 in the Republic of Korea in order to establish control measures. The present nationwide survey was conducted from June to December 2004. The 10% population sampling data of Population and Housing Census by the Korean government in 2000 was used as the survey population. One sample was selected randomly from each of the 22,858 registered subjects, and a total of 20,541 people were ultimately included in this survey. Fecal examinations were performed by the cellophane thick smear and saturated brine flotation techniques. Pinworm infection was examined by cello-tape anal swab method. This survey also included a questionnaire study for a socioeconomic analysis. The total helminth egg positive rate was 3.7%, and the estimated total positive number among nationwide people was 1,780,000. The rates in urban and rural areas were 3.1% and 6.8%, respectively. As the total egg positive rate in the 6th survey in 1997 was 2.4%, the present survey showed that there was a considerable degree of increase in the prevalence rate of intestinal parasitic infections over the 7-year period following the 6th survey. The largest increases occurred in the egg positive rates of Clonorchis sinensis and heterophyids including Metagonimus yokogawai.

Korean housing developers are in a very competitive market and their way of attracting buyers is landscaping better than competing firms do. Thus, transplanting larger pine trees(Pinus densiflora S. et. Z.) is in vogue. A typical case is a pine tree about 30-year old, 35 diameters at breast height, transplanted 223 km afar from the Gangwon Province to Seoul. We estimated and compared carbon emissions during the whole transplanting works, and carbon intake by the tree if it survives 50 more years on site. Findings are; first, a large tree will take up and sequestrate approximately 90 kgC if it survives 50 more years. Second, transplanting works emit approximately 113.69 kgC, which is about 1.26 times of its possible future intake of carbon. Landscaping is a legal requirement for the purposes not only of aesthetics but also of environmental quality. Transplanting larger trees that came from a dam or a road building site may be inevitable and acceptable. However, transplanting larger trees long distance was evaluated to be harmful to the environment. It is strongly recommended to prohibit transplanting large trees. Landscape professionals need to guide clients to have desirable consumer attitude.

This study examines how single-person household expenditure patterns are different with respect to age and income groups using Tobit model. The expenditure data of the national household survey from 2006 to 2012 were used. The results show that income elasticities of all items are greater than 1 except for food & beverage, housing, water, electricity & gas, and Communication. Income elasticities are significantly different among consuming items. Additionally the income elasticities are also different between various age and income groups of single-person households. Therefore governments and businesses have to take this into account when devising their policies or strategies regarding single-person households. Especially, businesses need to adopt a strategy targeted at single-person households with high income and buying power such as unmarried professional people. As the number of single-person household increases the proportion of expenditures on necessities such as beverage, food, and energy is expected to decrease while that on services increases. Consequently policy responses are required to prepare for the expansion of service industries such as health, hospital, and housekeeping services.

In the Chinese construction industry, the utilization of Building Information Modeling (BIM) aims to increase the total output of the construction industry by solving the problem of inefficient interoperability in the construction industry. In 2011, the Chinese Ministry of Housing and Urban-Rural Development despite the technical advantages of BIM and the government policy, the BIM adoption rate in China is lower than 45%. Meanwhile, as the South Korean construction industry is a step ahead of its Chinese counterpart in introducing and utilizing BIM, it is expected that BIM is more actively utilized and accepted in South Korea than in China. According to a comparative study based on the hype-cycle theory, South Korea is at a more advanced stage of introducing BIM, than in China. This study aimed to suggest how to increase BIM utilization rates in China. To this end, this study comparatively analyzed factors affecting BIM acceptance between China and South Korea. For the comparative analysis of the BIM acceptance factors between China and South Korea, literature reviews on the technology acceptance model (TAM) and BIM acceptance model were carried out, and based on that, the BIM acceptance factors were classified. Other BIM acceptance factors were also added and considered, as they reflected Chinese national characteristics and construction industry. As for the derived BIM acceptance factors, construction project participants, especially actual BIM users in China and South Korea, were targeted for the survey. A t-test using SPSS 22.00 was carried out to identify significant differences in data. Finally, based on the t-test results, this study suggested ways of improving the BIM utilization rate in China. Based on the findings, this study is expected to contribute to activating BIM adoption in the Chinese construction industry and also to set a theoretical foundation for future studies on BIM utilization in the industry.

This study surveyed residents and public officials for the projects to make smart-city plans of Geumsan-gun. First, domestic and foreign cases related to smart city projects were reviewed. The local status of Geumsan-gun was investigated regarding various aspects of the natural, social, urban environment, and smart-city facilities. The survey results were as follows. Overall, more than half of the survey respondents said they were satisfied with their housing quality. Several problems in their areas, such as inefficient welfare system, shortage of parking space, and industrial infrastructure, were reported. On the other hand, tourism and leisure facilities, health care support systems, industries to boost the economy, and the job market were also important issues. The problem was that the regional problems mentioned above were not in line with their preferences for smart-city services. The implications of the survey results could be summed up as follows. The groupware surveys of Geumsan-gun should be used as survey tools, whereas IT survey tools (Google, Survey Monkey, etc.) should be used for locals. In particular, a survey targeting residents should ask plain and compact questions taking advantage of local gatherings. It is also important to have a pilot-survey with relevant public officials and select related projects and regional issues. The survey of local residents and public officials is a prerequisite for promoting smart city projects. The smart city project shall reflect the needs of residents while solving community problems by considering the survey results and local conditions.
