This study aims to find out ways of improving life satisfaction of rural elderly by investigating their work and leisure activity, two significant axis of the life in later life. For this purpose, researchers and one assistant researcher visited house, senior citizen's center and health center, in order to have interviews with senior citizen above 65, who are currently working in the field. The summary of the research findings are as follows; First, the average size of the farm land which each senior citizen works on is $9,237.92m^2$ and they mostly work for economic reason. During farming season, they work on average 8.62 hour per day. As primary reasons for why farming work is difficult, "insufficient income" was picked. In fact, the average annual income senior citizens earn from farming is about 15.4 million won. 49.1% of sample senior citizens work both on watered farm and farm, and they are engaged in farming 48.82 years on average, showing that most of their lives have been spent on farming. In spite of these difficulties, most senior citizens showed high intention to continue farming work further. Second, senior citizens turn out to spend their leisure time mostly on public leisure activities such as watching TV, hearing radio and gatherings with families, relatives. However, individual activities such as meditation, yoga, drawing and calligraphy turn out to be low because they require foundations to enjoy. Third, senior citizen in rural areas were divided into four groups by farm work and leisure activity: group separated from work and leisure activity(27.09%), group centered to leisure activity(24.42%), group centered to work(23.75%), and group integrated work and leisure activity(23.75%). Fourth, the groups were different depending on demographic characteristics. Namely, male senior citizen, higher educational level, living in elderly couple households, and satisfied with their economic level belonged to the group integrated work and leisure activity. But senior citizen aged above 65 years old and working for their livelihood belonged to the group centered to work, and most of female and senior citizen aged above 80 years old belonged to the group separated from work and leisure activity. Finally, as the result of analysis of differences in life satisfaction according to farm work and leisure activity of senior citizen in rural areas, the group integrated work and leisure activity, and group centered to leisure activity were higher in life satisfaction than the group separated from work and leisure activity, and group centered to work. The above result indicates that life satisfaction of senior citizen depends upon leisure activity rather than work.

Personal information processing works, including resident registration number is common to be consigned by IT specialized company due to high level expertise and tremendous cost. The accident related to personal information is increasing and most of accidents are caused by the consignee's leaking information. According to the Inspection of personal information protection and the management level diagnosis of personal information protection, public Institutions need to build the consignee's accident prevention and personal information management system as soon as possible. In this paper, the efficient enhancement ways for the personal information protection is studied. We analyze the law of business consignment and select basic management items related with personal information protection, and propose a analysis scheme for management level of personal information protection and a enhancement scheme for management system of personal information protection. This paper suggests consignee's management system of personal information protection for the enhancement way and the three Strengthening ways in law. To compose the a enhancement scheme for management system of personal information protection, we conduct questionnaire survey to 30 consignees(IT maintenance, notice printing, call center, welfare center) related to typical tasks of public organizations, present reference for this scheme, and execute verification of this scheme by focus group interview of consignor and consignee.

The importance of fusion and association using established spatial information has increased gradually with the production and supply of various spatial data by public institutions. The generation of necessary spatial information without field investigation and additional surveying can reduce time, labor, and financial costs. However, the study of the integration of the newly introduced road name address map with the digital map is very insufficient. Even though the use of the road name address map is encouraged for public works related to spatial information, the digital map is still widely used because it is the national basic map. Therefore, in this study, building matching and update were performed to associate the digital map with the road name address map. After geometric calibration using the block-based ICP (Iterative Closest Point) method, multi-scale corresponding pair searching with hierarchical clustering was applied to detect the multi-type match. The accuracy assessment showed that the proposed method is more than 95% accurate and the matched building layer of the two maps is useful for the integrated application and fusion. In addition, the use of the road name address map, which carries the latest and most frequently renewed data, enables cost-effective updating of new buildings.

In the domestic construction industry, large-scale housing construction projects are being carried out by construction companies with competitiveness in the domestic top 10, it is said that the competence of the construction engineer is a factor for the success of the project. In Korea, there is National Competency Standards (NCS) that systematize contents of knowledge, technology, and attitude required in order to perform job in industrial field as the importance of individual ability is systemized in the country. Therefore, in this study, defined the detail competence in construction administration works, and examined the level of competence and degree of impotance detailed competency of construction engineers using AHP analysis & ANOVA. As a result, it was found that the current capacity of the Engineers in the apartment construction work is insufficient compared to the level of the competence they think they have, and that they have different competencies depending on their work experience and job position. This means that if the career is accumulated, the capacity that is possessed naturally will be changed. Therefore, it will be necessary to improve the capacity of the construction engineers who have a short work experience and a low job level.

This study has developed a forest fire occurrence probability model for inaccessible areas such as North Korea and Demilitarized Zone and we have developed a real-time forest fire danger rating system that can be used in fire-related works. There are limitations on the research that it is impossible to conduct site investigation for data acquisition and verification for forest fire weather index model and system development. To solve this problem, we estimated the fire spots in the areas where access is impossible by using MODIS satellite data with scientific basis. Using the past meteorological reanalysis data(5㎞ resolution) produced by the Korea Meteorological Administration(KMA) on the extracted fires, the meteorological characteristics of the fires were extracted and made database. The meteorological factors extracted from the forest fire ignition points in the inaccessible areas are statistically correlated with the forest fire occurrence and the weather factors and the logistic regression model that can estimate the forest fires occurrence(fires 1 and non-fores 0). And used to calculate the forest fire weather index(FWI). The results of the statistical analysis show that the logistic models(p<0.01) strongly depends on maximum temperature, minimum relative humidity, effective humidity and average wind speed. The logistic regression model constructed in this study showed a relatively high accuracy of 66%. These findings may be beneficial to the policy makers in Republic of Korea(ROK) and Democratic People's Republic of Korea(DPRK) for the prevention of forest fires.

This study was intended to provide basic data for increasing the interest in health projects for the public servants and local residents in the period ahead by examining the difference in the degree of interest in health projects among the public servants at resident centers and the residents. For that, 46 public servants at resident centers and 107 local residents were sampled, and their degree of interest in specific health projects was analyzed based on Chi-Square and independent sample t-test. Based on comprehensive consideration of the results of analysis, public servants at resident centers were found to have lower interest in health projects than local residents. The results of this study showed that the public servants at resident centers had lower interest in health projects than local residents. That arises from the consideration that specialization is important for implementation of special works. Thus, this study needs to focus on expanding the role of public servants to ensure that resident centers can take on integrated role related to public health. Therefore, the results of this study can provide basic data for expanding the role of public servants at resident centers. Moreover, the results of this study suggested that various ways need to be explored to increase the interest in health projects for local residents.

This study was conducted to determine factors causing urban temperature rises in a mixed urban and rural city in Korea. The study site was Miryang City. For this study, temperature changes over a 36 year period from 1974 to 2010, as well as changes made in the urban environment of the city were examined. Changes in the urban environment included data pertaining to both urban development and changing land use, as well as the changing lifestyle patterns of the populace. The study showed that a rise in the average annual temperature and the average annual mean-maximum temperature were statistically significant and the greatest determining factor for the temperature rise was a corresponding decrease in arable land. The study also showed that the decrease in cultivated land was directly and significantly related to an expansion of regional urbanization. There is a direct relationship between the decrease in cultivated land and an increase in the annual-mean-maximum temperature compared with annual-mean temperature. This increase can be explained as arable land works as an "island" of cooler temperatures in the hottest times of the day. A decrease of $1km^2$ of arable land is expected to cause an increase of $0.08^{\circ}C$ of annual-maximum-mean temperature and $0.06^{\circ}C$ of annual-mean temperature.

The prompt recovery of housing market in Korea became the national task, for which tools that can analyze the influence that changing situation of housing market and new policy may have on the housing market needs to be developed. Thus, this research intends to develop Multi-Agent Housing Market Model and simulation system in Jinju City as a study area. Analyzing the local housing market of Jinju City, then multi-agent model of housing market that consolidates 3 sub-models, house choice model, hedonic model of house price and location choice model is developed. Moreover in order to develop simulation system the model is programmed in the virtual space of which the size is $150{\times}100$ cell including physical shape of city such as road, urban facilities, land use, etc. With the system, simulations are performed to confirm the impact of urban development on the pattern of residential location. As a result, it is found that the residential location can not be easily induced when only road, commercial and convenient facilities are supplied. However, it is also found that since supplying green results in very many residences, arrangement of infrastructure and environmental factor should be considered at the same time for urban development. As conclusion, it is confirmed that the model and simulation system developed in this research smoothly works to be utilized for the analysis of diverse policy experiment and housing market.
