The purpose of this study is to present quantitatively the influence of variables that had the largest effect on the changes in suspended solids(SS), which would cause turbid water phenomenon, among water quality factors of the non-point pollution source, and then to develop a multiple regression equation of SS and predict the water quality of ungaged watersheds so as to provide basic data to establish efficient management plans for SS which flow in rivers and lakes. To identify the correlation of SS with the amount of rainfall and the state of land use, a simple correlation analysis and a simple regression analysis were conducted respectively. Finally, a multiple regression analysis was conducted to provide that SS were set as dependent variables while the amount of rainfall, paddy fields and dry fields were set as independent variables. As a result, the amount of rainfall had the most significant influence on changes in SS, followed by dry fields and paddy fields. In addition, the multiple regression equation was developed to predict SS in unmeasurable watersheds.

In the 21st Century, our society is facing decrease of general population and beginning of aging society due to low birth rate, and such issues are increasing the elderly population. Especially in Korea, the elderly population exceeded 7% of the total population in 2000, making its way to the aging society and the elderly population will increase up to 14% by 2019, becoming the true aging society. Unlike other countries, aging in Korea is happening very fast and this requires the society's preparation and plans to deal with the problem. This study was started with the problem that the welfare centers for elderly people in Gwangju do not have the space plan adequate for the regional characteristics and users' demands. Therefore, this study performed an investigation and analysis on service programs, management, and space formation of S welfare centers for elderly people in Gwangju. This study produced a figure after interviews with social welfare workers and surveys. And then this study investigated size and formation of space for the service programs in each welfare center This study showed the current status of welfare centers for elderly people and difference in size and formation of space related to the service programs of the region. Therefore, this study was done to provide the basic data for the space formation of new welfare centers.

The independent variables were analyzed and tested for their significant impact on the dependent variable, final buying decision of the product/service based on its country of origin. The selected hypotheses tested by administering the Kruskal-Wallis (K-W) hypothesis testing technique. The researchers identified that UAE consumers buying decisions influenced mainly by the country of origin of the products and services. The demographic variables like age, education, country of origin influential factors, country of choice was not displaying any significant impact on the buying decisions of consumers. The survey is limited to cover the general consumers of the country who are randomly selected from Dubai and Sharjah emirates.

Purpose: This research was performed to investigate Korean adolescents' body weight perception, appropriate weight change efforts, and factors that influencing these efforts. Methods: The data were obtained from 68,136 adolescents, aged 12~18 years from the 2007 Third Korean Youth' Risk Behavior Web-based Survey. Descriptive statistical analysis and odds ratio were calculated by logistic regression. Results: The distribution of the body mass index differed in boys and girls. The accuracy of body weight perception was shown in the order of the underweight (91.6%), overweigh t (73.3%), normal weight (55.4%), obesity (41.3%) groups. Adolescents with high perceived economic status tended to have a high prevalence of accuracy of body weight perception. The distribution of appropriate weight change efforts according to the actual body mass index showed that girls were trying to lose weight more than boys. The results of a logistic regression analysis regarding appropriate weight change efforts showed differences according to gender, perceived economic status, mother's educational level, and family affluence scale. Conclusion: Appropriate body weight perception and change management plans are needed for Korean adolescents. In addition, active weight change programs have to be established in the adolescents' living environments, such as schools.

By the result of analysis of effect of job-stress, satisfaction of the job, exhaustion, health status and immersion of the job were strongly related to job-stress. According to the general solution against job-stress that referred from job-stress related theses, there are several; Imagination Therapy, Assertive Training and Value Clarification Training could bring significant result. Conclusion: This study showed that because job-stress of clinical nurses had nothing to do with personal factors, job-stress management plans for nurses are needed to focus on occupational factors. Also the study suggested that various coping skills that proved to be effective are needed to be used to relieve job-stress and that's responses on nurses.

An analysis method of trajectory prediction has been suggested and the developed trajectory prediction module, which is an important functional component of the Arrival Manager (AMAN) of Jeju airport, has been tested by applying the suggested method. The objective of this method is to improve prediction performance of the trajectory prediction module. The trajectory prediction module predicts the trajectories based on the real-time track data and flight plans. Therefore, the suggested analysis method includes the simulation framework which is based on real-time playback, recording, and graphic display systems for testing. Besides, the definition of time error, which is a important index for the time based scheduling system, such as AMAN, is included in the suggested analysis method. An example of arrival time prediction accuracy improvement through the suggested analysis method has also been presented.

The purpose of the study is to analyze the residential mobility effects and planning discrepancies of home-owning households and renting households. The data for the empirical analysis were collected from 248 units residing in Ulsan and were studied using descriptive statistics, chi-squared tests by cross-tabulation and multiple regressions. The majority of the households did not experience a change in types of housing structure or ownership after the residential mobility. However, the housing size increased after residential mobility, showing that most moves were due to the deficit of housing sizes. In terms of future mobility plans, there were significant differences between home-owning households and renting households. More than two-thirds of the renting households were willing to move within 2-4 years to obtain home ownership. On the other hand, most home-owning households were willing to move for housing size, education of the head, and investment purposes. Compared to the forty-four percent of the home-owning households, seventy-two percent of the renting households were willing to relocate, which shows the effects of unstable housing circumstances.
