This study proposes an estimate method of willingness to pay(WTP) for real-time route guidance systems using contingent valuation method(CVM) under double bounded dichotomous choice question(DBDCQ) and analysis for impact factors of WTP estimation. This study assumed that provided real-time traffic information service is optimal route concepts dealing with traffic conditions on origin-destination. Analysis targets were classified into two groups as short distance path and middle distance path for estimating WTP for realtime route guidance system in a year using the survival analysis method and the regression model with personal information, actual condition and satisfaction of information usage and users' awareness and usage of facilities. As a result, mean WTP of realtime route guidance system is 4,034won/year in short distance path, and 4,884won/year in middle distance path. Therefore real-time route guidance system for longer distance path is recognized as more valuable than shorter distance path. Moreover, the necessity of information was required on a higher income group and higher WTP was estimated on owners of vehicle group and lower awareness of a route group.

The purpose of this study is to analyze the determinants of pay satisfaction of dental employees. The questionnaire used in this study consists of personal characteristics, characteristics of workplace, administration of pay, Pay satisfaction questionnaire (PSQ). PSQ was translated, and backward translation into korean was implemented. A pilot test was conducted with 25 dental employees to complete the questionnaire. Survey was conducted from February to July in 2015, receiving 323 valid responses. Anova or t-test was conducted with categorized characteristics, by calculating pay satisfaction scores. Principal factor analysis which is an exploratory factor analysis was conducted to investigate the consistency of pay satisfaction. Multiple regression analysis was conducted to investigate how much effect the variables have on pay satisfaction. The result of principal factor analysis showed that pay satisfaction consists of 3 factors which are 'paying system', 'pay level', 'benefits'. 'Pay raise' which was one of 4 factors of original PSQ was not the factor of pay satisfaction of dental employees. The result of analysis of characteristics showed that the scores of paying system between dental clinic and dental hospital had significant difference. The result of multiple regression analysis showed tendencies pay satisfaction increases when age and monthly income increases and whole career and the number of unit chairs decreases. Increasing the autonomy of employees and simplification of paying system would improve pay satisfaction efficiently. When age increases, the pay level increases because of the seniority-based pay structure, and this leads to the higher satisfaction. The higher amount of pay leads to higher satisfaction. The expectation over pay increases relatively higher than the increase of pay level and this leads to the less satisfaction. When the number of unit chairs is fewer, the workplace is smaller, so the employees have more autonomy, and this leads to higher satisfaction.

To analyze mobility patterns, this study used three Constraint (Capability Constraint, Coupling Constraint, Authority Constraint) models which were proposed in Dr. Hagerstrand's Time-space theory. This paper shows that three constraint models have some effects upon mobility by age. In this study, Capability Constraint means a certain special constraint that is what we can't do during proceeding basic natural urges like sleep, fare, etc. Coupling constraint is a physical one. Each person limits the action range for staying on a special place in special time. For instance, students have to stay in school so that they have mobility constraints. Authority Constraint is a social one. When we use urban facilities or traffic, we may be controlled by mobility sphere by an agreement or a social position. It is social agreement that the opening hour of a store, the time table of mass-transportation and a social positional control that the personal income, the standard of education. In this study it has been in a process of determination of the cluster number that degree of influences a social constraint to mobility. Considering the mobility constraint of characteristics of space divides urban and rural, people in urban area have higher mobility rate than in rural area. Resuets of determination of the cluster, show similar mobility pattern. People in urban area are connected verity of mobility which related to urban space structures with determination of cluste-number. That is to say, mobility patterns can be changed by space charactcristics. Constraints by sex and age are also social constraints and they are influenced by mobility patterns. For instance, females at the age of twenties have similar mobility pattern to the same age male but they have sudden changes after thirty's age. Male entertains a similar pattern without restriction of age. That is to say, management by sex as a social constraint affects mobility. To establish more realistic traffie policy, mobility formation should be reflected to the space in a view of social-behavioral science. To embody this, some problems should be investigated as follows. 1. As a problem of methodology, if sufficient samples ensured, we could subdivide clusters and could open up a new method of analyzing the mobility clusters by using the neuro-network. 2. Extracting actions connected with mobility and finding life cycle which is classified by daily cluste-characteristics, suitable counterproposal could be presented to the traific policy.

The aging process in this country is underway at the fastest pace compared to those of the leading countries. On the other hand, preparing for retirement funds is more difficult than before due to the impact of slow interest rate and slow growth. The purpose of this study is to examine the necessity of providing various financial services in preparation for the future aging era. After analizing the various materials and utilizing a survey of the bank employees and the general public, we have found the followings. The replacement rate of this country, 55%, is much lower than the suggested level of World Bank, 75%. Also, the pension ratio in the income after retirement of this country is much lower compared to those of the States and Japan. The most people who participated in the survey needed ￦2,000 - ￦2,990 thousand for monthly living expenses after retirement. For the retirement funds, the higher the age the higher proportion of savings deposits they want, and the lower the age the higher proportion of insurance and pension products they want. Based on these analyses, the necessities of developing financial life planning which includes both financial and non-financial sides, retirement funds management according to age, revitalization of housing pension and developing diverse retirement funds are suggested.

The reason that compulsory removals of a low-quality housing redevelopment such as involuntary or unintentional migration present a problem for urban communities is that whether involuntary movers adapt themselves to their new home has an influence on the urban communities that surround them. Moreover, involuntary emigrants have higher probability of choosing faulty residential areas than voluntary emigrants do. This gives rise to a problem of another residential migration for involuntary movers. In order to solve these problems, there is a need for a new housing policy that enables original residents to come back to their old community. However studies for resettlement had not conducted subjects about housing redevelopment characteristics which influences the involuntary movers directly. Instead personal microscopic characteristics such as statistics of resettlement, the moving distance, the reason of moving, improvement of living environment, had been main subjects of farmer studies. So the purpose of this study is to analyze an analysis of the relationship between resettlement and housing redevelopment characteristics. The data used in this study was obtained at 47 areas designated by Seoul (metropolis) since 1990 for redevelopment. Cluster Analysis Is used for dividing high rate of resettlement with low rate of resettlement and Regression Analysis is used for the analysis of the relationship between resettlement and housing redevelopment characteristics. The results of examining the effects of a redeveloped housing complex on returning residents at 47 areas designated by Seoul (metropolis) since 1990 fur redevelopment are as follows: First, A housing complex with a high returning rate (remove-in rate?) has no state/public land, unauthorized building owners who are in the low-income brackets, and few interested parties such as union members. This is the characteristic of a redeveloped housing complex with a short-period project span. On the contrary, a housing complex that has a low returning rate is crowded by state/public land, and numerous unauthorized building owners, and interested parties. Second, According to the linear regression analysis, among the factors that affect returning residents, 'physical properties(characteristics) of a region', 'population properties within a region', and 'properties of a project span' indicate a negative(-)influence whereas 'properties of a complex density' shows a positive(+) influence. In a nutshell, the more the physical properties, population properties, projectspan properties, the lower the returning rate and the more the complex density properties, the higher the returning rate. In detail, an area with many small land and new/large buildings, a high population, and a long project duration has a low returning rate of original residents while an area holding large capacity and buildings with many number of floors (multiple-storied building) has a high returning rate.

World security market has continuously been growing since the 2000s. The growth rate seems to reach up to 7-8% annually. What is more, Korea is expected to be one of the most rapidly developing markets, Based of this view, this research investigates the principal drivers to have affected on the expansion of Korean security market over the past 20 years. In addition to that, this study also examines the influence of recent changes in the world economy and globalization, socio-demographic change, development of information technology on the future security market. The data reviewed in this study are official crime rates, socio-economic indicators, statistics from the National Police Agency and the business reports of a leading private security company. This study shows that several factors such as rising crime rates, lack of police capacities, national economic growth and rising household income have played important roles in development of Korean market. It is also expected to keep those positive affects on the future market. On the other side, in recent years, the security market seems to be increasingly affected by new social economic changes. Those are impact of last aging society, rapid increase of individual household and women's participation in labor market. These factors seem to increase personal and household needs for security service. World economy, globalization process and development of information technology are also deemed to give rise to social demands for surveillance, monitoring service and security in cyber space.

Objectives : This study aimed to determine self-esteem and oral health impact profile (OHIP) of orthodontic patients to get data necessary for the process of consultation, education, and treatment for those patients who hoped to get orthodontic therapy in order to see effects of orthodontic therapy on personal life in consideration of general characteristics of those patients under orthodontic therapy. methods : A self-administered questionnaire was used among 232 outpatients under orthodontic therapy from October to November 2009, obtaining the following results. Results : 1. As for general characteristics of respondents, those under 19 years of age constituted 46.6%; the unmarried comprised 85.8%; and students constituted 53.4%. 2. Most respondents were getting orthodontic therapy for beauty (41.8%) and dental health (40.5%). Family (54.3%) contributed to their decision to get orthodontic therapy; parents or siblings (62.5%) were bearing the treatment expenses. 3. Females were getting orthodontic therapy for an aesthetic purpose (50.3%), and male for the purpose of dental health (44.6%) (P<0.01). 4. OHIP was slightly higher among males ($4.10{\pm}0.61$) than among female ($4.00{\pm}0.78$), and was highest among those 19 years old and under ($4.17{\pm}0.67$); the older they were, the lower it was significantly (P<0.05). Most of them were earning 3 to 4 million won ($4.22{\pm}0.72$); the married ($4.05{\pm}0.74$) constituted higher percentage. As for occupation, students ($4.13{\pm}0.66$) comprised the highest percentage. 5. Self-esteem was higher among males ($3.83{\pm}0.47$) than among females ($3.80{\pm}0.50$), and was highest among those 25 to 29 years old ($3.92{\pm}0.46$). Most of them were earning more than 5 million won ($3.91{\pm}0.42$), which was statistically significant (P<0.01). The married ($3.91{\pm}0.54$) constituted higher percentage than the unmarried ($3.80{\pm}0.48$); office managers ($3.95{\pm}0.55$) comprised the highest percentage. 6. As for correlation between variables effecting OHIP of orthodontic patients, there was negative correlation in age (r=-0.225) and positive correlation in occupation (r=0.122). As for correlation between variables effecting self-esteem of orthodontic patients, there was negative correlation in occupation (r=-0.130) and positive correlation n income (0.126), while there was positive correlation (r=0.202) between OHIP and self-esteem of orthodontic patients. Conclusions : Younger orthodontic patients who were students showed higher OHIP, and professionals earning more showed higher self-esteem. Orthodontic patients with higher OHIP showed higher self-esteem. Therefore, it is necessary to develop a program based on OHIP and self-esteem in consulting and treating orthodontic patients; since it is considered that orthodontic therapy will improve appearance, enhance self-confidence, and have positive effects on interpersonal relationships and quality of living, researches are necessary on constant changes in psychological properties.

The purpose of this study is to analyze both residential conditions and the resident impressions of the transition zone of central Daegu. The results drawn from a questionnaire survey of the residents are summarized as follows: 1) The proportion of people over the age of 60 living on a low income is high and consists mostly of retired citizens who have lived in the transition zone, in their own homes, for an extended length of time 2) The condition of infrastructure in the transition zone is very poor, however, despite the housing deterioration, the internal repair and maintenance of houses is more satisfactory than their external appearance. 3) Residential satisfaction received high ratings in every category except pollution and housing price. This response appears to stem from the easy commute of residents as well as the ready availability of facilities in the city center. 4) In terms of residential satisfaction, the residents can be divided into two groups. The first, with a high satisfaction rate, consists mainly of senior citizens who possess both personal homes and a stable living, having resided in the city center for most of their lives. The second, with a lower satisfaction rate, is composed mostly of younger residents who have lived temporarily in inexpensive rental homes. As a results, the residential area in the transition zone of central Daegu does not appear to be a problematic area like the slum of the West, but instead a stable settlement for its residents.

Purpose : the management of University Hospital is being challenged in maintenance of reasonable level of income and high ranked reputation by domestic competition with each other and emergence of enterprised owned hospitals. It is imperative that University Hospitals have to make management for patient satisfaction. Furthermore, increased patient's requirement for qualified hospital services (quality assurance) and low-estimated service fee also repress the hospital management condition as well as medical markets open following with Urguay Connection. Due to these unforable conditions surrounding hospital management, -University Hospitals are being pressed to seek improved management strategies. To develope the strategies, we need to have basic understanding about the problems on hospital management and detail information for various patient's requirement. Methods: For this study, we have analysed out-patients from five different University Hospitals located in Seoul, Korea. To obtain the data, we have carried out personal interviews with patients who patients who visit the Out-Patient Clinics of five different University Hospitals using a previously prepared questionnaire. Result: Around 65.7 percent of the visits to University Hospitals were indwelt in the vicinity of 1 hour and motuvation of visiting University Hospital was expending high wuality medical csre in 49.3 percent. The 79.3 percent of the patients have experienced inconvenience during medical care in University Hospital. The most inconvenient condition was waiting for doctors. The 57.2 percent of total patient have experienced rudness. The most rudness condition was registration and receipt desk in 44.4 percent. Patient expect that doctors working in University Hospitals as professors have high and updated medical knowledge(50.4%) and University Hospitals have a high quality medical care system(79.4%). The patient satisfaction was relatively low in 61.1 percent of total patient and revealed high frequency of again visit University Hospital in satisfaction group. Comparison of interhospital analytical study showed quite difference on various problems. Conclusion: Almost patients who visit to Out-Patient Clinic of University Hospital havevisiting motivation to high quality medical care. University Hospitals have several different unsatisfactorial factors and revealed different degree of patient satisfaction. In a future day, University Hospitals have to make use of another University Hospital's merits for approach of Benchmarking and also should be studied decision factors of patient satisfaction and interhospital difference of them.
