The purpose of this study is to deliver both market-practical and civil-centric political implication for sharing economy by investigating the nature of consumer-adoption for car-sharing service. With the global interest and market proliferation of the sharing economy, various service models for sharing idle resources have also been released in Korea. Particularly, in case of car sharing service, public - private partnership projects are spreading rapidly in various local governments including Seoul, along with the growing demand for alternative transportation system centering on the urban area. This study conducted an empirical study on the process of accepting the car sharing service by analyzing the data collected from users of the car sharing service "Sharing Car(Nanum Car)" of Seoul Metropolitan Government. A survey was conducted on 281 users in their twenties who are in the age of main use among the experienced users of the "Sharing Car(NaNum)" residing in Seoul. The result of analysis on the relationship between these users' perceived value and intention to use the vehicle sharing service would provide implications for establishing consumer(citizen)-centeric policies as well as market implications.

In contrast to standard train tracks, tramlines are often set along public roads, with trams running among pedestrians and other vehicles. In some cities and towns, trams and buses share the same routes and stations. Under the current investment appraisal system, trams are classified into light rail when predicting traffic demand and calculating benefits, but in the case of non-capital areas, it is notable that the origin-destination and transit lines of buses are not provided in the Korea Transport Database distribution data. Due to this problem, it is difficult to reflect proper mode changing behaviors between route buses and trams. This study examines the impact on tramlines of bus routes that are not currently considered in non-capital areas. Following an analysis of the effect of tram projects according to whether bus routes are considered or not, an improvement in methodology is proposed. Through this study, it is expected that the investment appraisal system for the planning of new tramlines will be improved in the future.

Objectives: As an ecological study, this study was performed to identify the community-level variation of health related quality-of-life (HRQOL), and to explore the factors that explain the variation, using 2017 Korean Community Health Survey (KCHS) data. Methods: Community health indicators of KCHS, which are correlated with the EQ-5D index of Si-gun-gu districts, were selected as independent variables. Multiple linear regression model was used to derive factors that explain regional variations in the EQ-5D index. Results: The EQ-5D index variation in 229 districts nationwide was 1.1 times for extremal quotient (EQ) and 1.0 for coefficient of variance (CV). The Si-gun-gu districts with the EQ-5D index in the lower 25% were more distributed in the province (27.7%) than in the metropolitan area (20.3%). As a result of multiple linear regression analysis, the depressed mood experience rate, perceived stress rate, suicide ideation rate, and physician diagnosed arthritis rate were derived as major factors of the variation. Conclusions: In order to reduce the gap in HRQOL between the districts, the priority of local health policies should be placed on the above factors including psychosocial factors.

Modern society is steadily implementing policies to encourage public transportation to cope with the growing traffic demand on limited roads. The expectation is rising for transit signal priority to ensure the speed of buses as the installation of the bus rapid transit(BRT) expands nationwide to secure the competitiveness of buses. On the other hand, the form of BRT stops without considering some aspects of bus operation may increase the number of stops on the bus, thereby reducing the effectiveness of bus signal priority applications. This study suggests the type of bus stop to increase the operation efficiency of buses by analyzing the bus signal priority effect according to the BRT station type using Hannuri-daero, Sejong. The bus signal priority is used to maximize the two-way bandwidth of passenger cars and buses. As a result of the application, the effectiveness of the bus signal priority at the stop causing the double stop of the bus was reduced drastically, and the efficiency of the bus signal priority was increased significantly after improvement. These results are expected to be used as basic data in the form of proper bus stops considering the aspects of traffic operation when designing BRT stops in new towns in the future.

This work verifies the effect of Job Crafting on organizational commitment through innovative actions, and analyzes the regulatory effect, by setting up knowledge sharing among members as factors that promote Job Crafting and Innovative Action. Depending on the level of knowledge sharing, the indirect effects of Job Crafting from organizational commitment of the members through innovative actions are expected to vary, and the controlled mediated effects are analyzed. Totally, 463 individuals were surveyed, including start-ups, small and medium-sized enterprises, public institutions, and large enterprise workers. The hypothesis was subsequently verified through analysis by applying SPSS 18.0 and SPSS Process Macro. Our results reveal that Job Crafting has a positive impact on the innovation behavior of the members. Secondly, a higher level of knowledge sharing had a greater positive outcome in the member's innovation behavior. Third, all innovative actions positively impacted the organizational commitment of the members. The fourth notable point was that innovation behavior imparted only a moderate impact on the association between Job Crafting and Organizational Commitment. Finally, it was determined that there was no significance in the controlled mediated effect of knowledge sharing on the indirect effects of Job Crafting affecting organizational commitment through innovative actions. Based on the data verifying the hypothesis, we present here the theoretical and practical implications of this study.

This study aimed to improve the quality of forest healing program through analyses of the program activities given at National Healing Forest and surveys conducted by Korea Forest Service. 99 DB data of the healing forest that were surveyed by KFS (August 2015~April 2016) were collected in order to affirm the activities. We analysed DB based on the format of the survey by target, 6 healing factors, location, season, time periods, operation hours and multifaceted evaluation. The results showed that the activities in the forest healing program targeted general public and the factor that was considered the most was psychotherapy factor. Healing forest trails were used as a location, spring, summer and fall as season, morning and afternoon as time period for the majority of the activities. The running time was 60 minutes. The multifaceted evaluation revealed that dynamic activities were preferred the most in development of programs. According to the results of the forest healing programs, it seems to be critical to enhance forest healing instructors' diversified professionalism. However, this will only be achievable once further investigations regarding forest healing effects by types of illnesses are conducted and provide solid foundation for such professionalism.

This study looked at the concretizing process of the Free Semester Policy(as is the FSP). The concretizing process of policy refers to the process in which the major components of policy idea are changing through the agenda setting and policy decision process. To this end, we collected major policy documents related to the FSP from the pledge of the presidential candidate to the implementation plan of the FSP and the oral data of key personnel of the FSP, and analyzed the concretizing process of the policy focusing on the policy objectives. As a result, it was found that the policy objectives of the FSP were presented in a more comprehensive and ambiguous form through the agenda setting and policy decision process. The emphasized direction of policy has also changed over and over. This phenomenon offers several implications for understanding education policy. First, it should be understood that the objectives of education policy presented at a specific point in time are provisional. Second, the change in policy objectives may have occurred in the process of securing the legitimacy of policy promotion. Third, it is necessary to pay more attention to the relationship between policy and politics. In order to properly promote an education policy based on the common sense and needs of the public, a mature education policy discussion culture is required.

The purpose of this study was to identify the self-awareness of smartphone dependence among undergraduate students and their response to the same. The data was drawn from a survey on smartphone overdependence conducted by the Ministry of Science and information and communications technology (ICT) and the National Information Society Agency in 2017. The responses of 1,735 undergraduate students were analyzed by frequency, percentage, mean, standard deviation, minimum-maximum value, ��2-test, independent t-test, Pearson's correlation coefficient, and stepwise multiple regression analysis. The results indicated that 22.3% of participants were at risk of smartphone dependence, and 63.6% of them were unaware of their dependence on smartphones. The perception of smartphone dependence was significantly associated with a higher risk of smartphone dependence (��=.35, p=.000) and the increasing use of applications such as games (��=.19, p=.000), television/video (��=.11, p=.000), and learning (��=.11, p=.000). Of the participants with dependence awareness, only a few knew about the existence of centers to prevent smartphone and internet dependence. Moreover, they rarely utilized these centers. However, the participants felt the need for more counseling agencies (26.8%), programs for dealing with oneself (23.2%), information about smartphone dependence (14.9%), and help to overcome dependence (10.9%). These findings show the need to establish public services so that students can easily access correct information on smartphone dependence and address this problem.

GPR is used for non-destructive investigations, ground investigations, and underground facilities exploration at construction sites. In this study, the applicability to GPR exploration of water pipes linked to Network RTK was presented. Data on the water supply pipes in the study site were acquired using GPR, and the location and depth of buried water pipes could be measured. The accuracy was evaluated from the GNSS observation performance and showed a deviation of -0.16m ~ 0.15m. This satisfied the equipment performance of the public survey work regulation, suggesting that the exploration of water pipes using GPR is possible. Because GPR does not require grounding installation, as in conventional metal pipe detectors, it will increase the efficiency of work for underground facility exploration. Exploration using GPR can acquire the location and depth of metallic and non-metallic underground facilities, so it can be utilized in the construction of a GIS system. If a comparison of the exploration characteristics is carried out, it will be possible to present various uses of underground facility exploration using GPR.
