GPS which measured user's location information outdoors should be of poor sensitivity because of interference and jamming of different electromagnetic waves. Specially, it has a defect of low received rate in high-rise urban where reflection and refraction of satellite signal go well. In this paper, I propose user location information sharing modeling of both vehicle and mobile phone using bluetooth in urban.

This study investigates the differences among residental areas in the health, standard of living, and social relationships of female elderly living alone. The total of 501 subjects(185 from rural areas, 159 from fishing communities, 77 from the islands, and 80 from urban areas) were questioned from May to July, 2006. The research area was confined to Chungcheong Province. The female elderly living alone of this study were an average of seventy-three years old, had a low cost of living, and received little formal school education. Over sixty percent(60.3) of them lived on less than thirty dollars a month which was the recognized Korean poverty level in 2006. The female elderly living alone were evaluated as being in good health, but they themselves perceived their health as being poor. Observed by residential areas, the subjects in urban areas were lower in ADL, and both the urban dwellers and the islanders appeared to be higher in their satisfaction with medical services as compared to those in rural areas and fishing communities. The fishing villagers showed the lowest standard of living for female elderly living alone. The analysis of social relationships as seen in the different residental areas revealed that the female elderly living alone g in urban areas tended to be receiving social supports rather than providing for others, and subjects living in fishing areas and the islands proved to be relatively higher in the exchange of social supports. In relation to offspring, the female elderly living alone in urban areas had a lower frequency of meeting with their children and also a lesser degree of intimacy with them because they lived at a distance. On the other hand, subjects living in rural areas and fishing communities had a higher frequency of meeting with their children and a greater degree of intimacy with them even if they lived at a distance. The study also showed that the female elderly living alone in the islands had a higher frequency of once meeting per three week with their offspring and a higher degree of intimacy with them because they all live in the same islands. In conclusion, the subject living in urban areas appeared to be isolated from their offspring as compared to the other seniors in the study. The female elderly living alone in urban areas suffered from an insufficient network of relatives and neighbors, and they experienced a poor quality of relationships to their offspring. Almost all of the lone seniors in the study had a low score in social activities; however, the female elderly living alone in urban areas revealed a higher level of participation in volunteer activities, group activities, and educational activities. Nevertheless, the lone seniors living in urban areas were not satisfied with their participation in social activities. The subjects living in rural in fishing communities and the islands showed more participation in money-making activities. This study suggests that the policies for female elderly living alone should reflect the differences of regional characteristics.

The purpose of the this study was to provide the basic information about the formation background of urban squatter and their housing state in Korea. This study was progressed on the basis of socio-historical point of view from after the Korean War to the present time. Therefore, this study considered the meaning of housing for urban squatter in the Korean housing history. For this study, the formation background of urban squatter was divided into five periods. The first one was the period of the policy on the mass migration (1955-1960) after the Korean War. The second period was the period of reproduction of deteriorated residential area (1960-1970) for the continuing mass migration policy. The third was the period of disbanding of deteriorated residential area (1970-1980) for redevelopment. The forth period was before the IMF (1980-1997) broke up the deteriorated residential area. The fifth period was after the IMF (1997-) produced the new poverty due to the unemployment and the business failure. Thus, such social change increased the number of urban squatter and created the new type urban poor.

As a household's residential location is closely related to its workplace and place of education, the urban exodus of city dwellers changes their ways of commuting to workplace and attending school. This paper examines the influence of urban exodus on the change of a way of life through relations between residential location and modes of commuting. Despite moving to the countryside, exurban migrants still want to experience rural health without abandoning the city lifestyle. However, they are faced with various difficulties in commuting to workplace and attending school, because suburban and exurban areas have poor accessibility to the central city. In order to overcome these problems, most of them choose "the residential segmentation of the family" through which the head of the family commutes to the city from his or her family home in exurban areas and children go to school from their second home in the central city, or try "to link commuting to workplace with attending school".

In order to investigate of possibility for developing urban wind power, wind profile and wind power density are estimated using Sodar and Lidar based on surface. Since poor performance of Sodar and Lidar are often shown in a paticular meteorological condition, inter-comparison and validation with radio-sonde for each of instruments are performed. As a result, Lidar shows a good performance and wind data from Lidar are used to analyze wind profile and wind power density. It can be found that a wind power system mounted tall building in urban area is very attractive.

This study has examined the degree of depression and anxiety among high school students in an urban area and then explored the factors influencing their depression and/or anxiety status. Self-administered questionnaires were offered to 2,381 students from ten high schools in Daejon Metropolitan City. The items for investigation included such factors as various characteristics of school and family life, daily life style, and the degree of depression and anxiety. Based on the study results, the following conclusions were made； 1. The distribution according to the depression degree has shown that 61.9％ of students were normal, 32.9％ of students had mild depression, 5.0％ moderate depression, and 0.3％ severe depression. As for anxiety, 40.2％ of students were normal, while 19.1％ were classified as having anxiety and 40.7％ borderline anxiety. 2. As regards to the degree of depression and anxiety, it was greater in girls than boys, in 3rd graders than 1st and 2nd graders, and in the groups who have recieved lower grades in studies, who had poor relations with their friends and a low feeling of satisfaction with school life. In particular, concerning various characteristics of family life, the scores of depression and anxiety were higher in the groups whose financial conditions were poor, whose parents' interests were lower, whose degree of satisfaction with their family and school life was lower, than their counterparts. 3. According to their life styles higher scores of depression and anxiety were found in the groups whose sleeping time was inappropriate, whose breakfasts were skipped, who ate daily snacks, who didn't take regular exercises, and who had poor health habits, compared to their counterparts, respectively. 4. As for the correlation between the degree of depression and its associated variables, the higher scores of depression were in positive correlation with the groups who had lower grades in studies, poor relation with their friends, low feeling of satisfaction with school and home life, low parents' interest, poor subjective condition of health, breakfast skipping, lack of regular exercises, and lower indices of health habits. 5. As for anxiety, the higher scores of anxiety were in the positive correlation with the groups with poor relation with their friends, low feeling of satisfaction with school and family life, poor subjective condition of health, lack of regular exercises, and poor health habits. 6. The influential factors on the depression of students were selected such as subjective condition of health, sex, feeling of satisfaction with family and school life, grades in studies, relation with their friends, presence of regular exercises, degree of interest of parents, sleeping time, cigarette smoking and eating breakfast. 7. The influential factors on the anxiety state of students were selected such as subjective condition of health, feeling of satisfaction with family and school life, sex, sleeping time, regular exercises, cigarette smoking, snacking and relations with their friends. The present study results suggest that girls rather than boys, higher graders than lower ones are more vulnerable to anxiety and depression state, and besides, various characteristics of school and family life, and daily life style can be influential on students' emotional states. Therefore, better management of psychological status of students is thought to require a wide variety of measures to modify the influencing factors and to encourage social support.

This study investigates the difference in income trajectories of the working poor and the non-working poor and explains the effects of socio-demographic (marriage, education) and regional (living in large cities) factors on intergroup differences. We use Seoul Survey data collected between 2009-2018 and the latent growth modeling approach. It was found that the trajectory difference between groups was statistically significant. Since 2016, the income gap widened as the income of the working poor stagnated. The three variables included in this model better explained the income trajectory of the working poor compared to the working non-poor. In particular, the change in income growth rate was positively related to whether they live in large cities. This suggests the possibility that living in a large city would act as an economic premium for the working poor. It is necessary to conduct follow-up studies on urban premiums for the working poor.
