Currently, various types of TDM (Transportation Demand Management) policies are being studied and implemented in an attempt to overcome the limitations of supply oriented policies. In this context, this paper addressed issues of effectiveness and possible domestic implementation of the HOT lane. The possible site of implementation selected for this simulation study is part of the Kyung-bu freeway, where a dedicated bus lane is currently being operated. Minimum length of distance required in between interchanges and access points of the HOT lane for vehicles to safely enter and exit the lane, and traffic management policies for effectively managing the weaving traffic trying to enter and exit the HOT lane were presented. A 5.2km section of freeway from Ki-heuing IC to Suwon IC and a 8.3km section from Hak-uei JC to Pan-gyo JC have been selected as possible sites of implementation for the HOT lane, in which congestion occurs regularly due to the high level of travel demand. VISSIM simulation program has been used to analyze the effects of the HOT lane under the assumption that one-lane HOT lane has been put into operation in these sections and that the lane change rate were in between 5% to 30%. The results of each possible scenario have proven that overall travel speed on the general lanes have increased as well by 1.57~2.62km/h after the implementation of the HOT lane. It is meaningful that this study could serve as a basic reference data for possible follow-up studies on the HOT lane as one effective method of TDM policies. Considering that the bus travel rate would continue increase and assuming the improvement in travel speed on general lanes, similar case study can be implemented where gaps between buses on bus lane are available, as a possible alternative of efficient bus lane management policies.

A parking facility choice model. which can be applied to analyze of the driver's parking behavioral changes in response to the local government's parking policy changes and to predict parking demand by the facility types, is developed. Under the context of the stated preference discrete choice model, socioeconomic variables and parking alternative characteristic variables are introduced as explanatory variables. A parking facility choice model for the shopping trip purpose is derived using multinomial logit model and nested logit model and the stated preference data collected in Taegu metropolitan area. The result shows that the sign of all the estimated parameters are logically consistent and the model's goodness of fit is reasonably good. As a result of the elasticity analysis of the model, the elasticity of parking cost is highest, and the elasticity of walking distance between parking place and the destination is higher than parking place searching and ingress time. This means that the parking places are supplied around the destination in the form of small-size parking place. The findings in this study is expected to provide a fundamental data for various short-term parking policy analyses and for parking facility's demand estimations.

A two-way left-turn lane is a continuous center left-turn lane that could be used as a deceleration and refuge area for both directions of left-turning vehicles. TWLTL's have been used effectively for access management treatment when applied to a highway that has wide-spread left turning traffic demand and a high-density of side streets. In this study, an effective analysis was carried out using a computer-based simulation tool, VISSIM, in order to evaluate performance and safety effects of TWLTLs and develop a warrant. In conclusion, the results indicated that there was a remarkable decrease of through and left-turning vehicle travel time delay on the main road and improvement of traffic safety.

The purpose of this study is to approach for the flow analysis of changing central-place functions and basic demands between the central city and the small town. Under the rural society progressed, this study examines how the small town changes in the relation to the central city. The subject of study is based on changes in demand for retail and hospitality. The small town is providing basic demands and urban services primary for the rural in the settlement system. Because of the rural depopulation and the aging of society, Retail and hospitality in the rural is reducing of the facility followed. But the majority of related researches are stocks approach. These studies are useful to find out the characteristic of small town, but is difficult to consider the influence of the central city. In this situation after this study using the function index is set up a concept model, it examines for the basis of changes in demand for the small town. The result of the analysis is that the changes of retail and hospitality are more severe in the more small town than in the central city. Whereas the small town with a population decline is consistent with the reduced number of branches, Population growth in the central city is reduced to the number of the Number of branches. The central-place function has been strengthened in the central city. While the younger generation, recreation, etc. related retail are disappearing rapidly, the mainstream of small town is grocery, home improvement, restaurants.

Recently, security issues on industrial technology are undergoing rapid changes around the world. Developed countries are establishing response strategies to protect their own core technologies while creating conflicts with global value chains and foreign capital movement. Also in Korea, we are approaching industrial security issues in the mid- to long-term industrial competitiveness. The purpose of this study is to survey on the awareness of the industrial security ecosystem and derive key policy issues. Based on a three round survey, four policies were suggested as followings : systemization of industrial security control tower, enhancement of security company's technical skills and training of security specialists, improvement of technology leakage prevention system through retirement personnel and M&A, reinforcement of research security in R&D process and proactive technology protection. It is hoped that this study will serve as a basis for policy-making as an evidence-based study reflecting the policy demands of industrial security.

The purpose of this study was to make a basic research on college cultural contents education in an effort to step up the manifestation of the creativity of cultural contents experts in line with the development of the fast-changing era of creative economy. It's basically meant to analyze the characteristics of cultural contents education in relation to creative idea to seek practical ways of improving that education. What problems there were with cultural contents education and how that education was actually provided were analyzed to suggest some of the right directions for client-centered cultural contents education. Earlier studies were analyzed, and the results of a survey that was conducted on students whose major was linked to cultural contents were analyzed as well. As a result, current cultural contents education was considered not to be satisfactory due to existing teaching methods, learning process and curriculums that were devoid of creativity. To rectify the situation, interdisciplinary attempts should be made such as multi-major, interdisciplinary programs or convergence education, and plenty of experiments, sufficient practice and an increase in the number of faculty members are all required. In terms of education, existing curriculums and courses should urgently be revamped to strengthen field placement and creative discussions. As for educational methods, the lecture method should be avoided, and specialized education should be offered instead, which should strike a balance between discussion, team play and project education. It is expected to produce good results if there are appropriate connection among different major fields of study and the harmonious implementation of diverse internship, convergence and field placement programs.

The objectives of this research are: to provide fundamental data for tourism policy and investigate medical tourism attributes by IPA(Importance-Performance Analysis) to attract Japanese medical tourists to Korea. Utilizing Japanese medical tourists as subjects of inquiry, this study evaluated the importance of medical tourism selection attributes and the rate at which these attributes were performed. Consequently, this study deduced 'convenience, service quality, differentiation, approximation' factors by factor analysis as well as the ranking among each selection attributes using T-test. The importance-performance analysis showed 'Concentrate Here' in quadrant I, 'Keep up the Good Work' in quadrant II, 'Low Priority' in quadrant III and 'Possible Overkill' in quadrant IV. The results show that "Concentrate Here" part in quadrant I is reservation procedure rapidity and information system simplicity. This means that these attributes are very important but they indicate low performance. Thus, concentration among tourism managers should be focused along these attributes. The study, then, suggests that employee who speaks Japanese fluently should be arranged during reservation procedure. Furthermore, Japanese class should become mandatory during basic employee training to improve reservation procedure rapidity. Moreover, clinic websites should concentrate on accessibility of Japanese users in such a way that they can consult their needs on line. Finally, managers should find diverse ways to bring about good service rapidly and conveniently.

This study explores the status, characteristics and problems of urban-to-rural migration policy in Gyeongbuk Province, and suggests some improvements based on this analysis. Gyeongbuk Province enacted local ordinances related to urban-to-rural migration for the first time in Korea, and has expanded the area of its own projects in addition to the central government's support projects. Consequently, the degree of satisfaction for the support projects in Gyeongbuk Province is higher than in other provinces. Problems of the support projects for urban-to-rural migration are the lack of role sharing between central and lower level local government, and the lack of connectivity among the relevant departments; the non-reflection of regional characteristics and attributes of urban-to-rural migrants (household); and the insufficient satisfaction of policy demands by non-agricultural urban-to-rural migrants. Improvements for these problems include establishing governance that involves urban-to-rural migrants in addition to the existing policy actors, and institutionalizing the project to properly embed this governance in the region. In addition to economic and physical support, diverse programs based on the adaptive cycle, 'non-agricultural rural jobs' for nonagricultural urban-to-rural migrants, and support programs for professional competency enhancement contributing to rural communities should be developed.
