  • A subway system is one of the major transportation modes at a metropolitan area. When it meets the other lines, the metro station, so-called transferring station, is usually threatened by severe pedestrian congestion and safety issue of transit users including the transportation vulnerable. Although transportation planners forecast travel demand at the beginning, it is not easy to predict pedestrian flows precisely for a long term if land use plans have dramatically changed. Due to expensive costs, structural extension of metro stations is limited. Therefore, it requires efficient and technical improvements as meeting the demand of pedestrian and physical characteristics. In this study, the core mechanism of pedestrian movement-based simulation model was introduced and evacuation scenarios were analyzed with the developed model. As a result, the multiple optimal routes for unexpected events at the solid space of the multiple stories are easily searched through the simulator and in the case of Sadang Station, travel time can be reduced by 60% when the evacuation information and intuitive design are provided.

  • The Gwangyang City of Jeonnam Province, is one of the steel cities representing the Korea. Gwangyang Steelworks are the core of the local economy, and 59 firms of POSCO Outsourcing Partner Cooperation(POSPA) have been employed 9,300 to 9,500 peoples, and have been acted as an central incubator for job creation. POSPA, however, are suffering from the retirement of company in young age group, in their 20s and 30s. The purpose of this study is to analyze potential job seekers' perceptions and job preferences for POSPA are suffering from job openings. In order to this research purpose, it used questionary survey, and sample groups were divided into three areas, the Eastern Jeonnam Province, Gwangju, and the Seoul metropolitan area. Potential job seekers' perceptions for POSPA was low, and perceptions on firm and job opportunity information was lower. This characteristics were the same as those of respondents living in eastern South Jeolla Province. Potential job seekers, however, showed high preference for finding job at POSPA. A place-based policy considering the local labor market is needed to resolve the mismatch between the difficulty of finding a labor and the difficulty of finding a job.

  • The genetic algorithm (GA) and branch and bound (B&B) methods are the useful methods of searching the optimal project combination (combinatorial optimization) to maximize the project effect considering the budget constraint and the balance of regional development with regard to the Urban Regeneration New Deal policy, the core real estate policy of the Moon Jae-in government. The Ministry of Land, Infrastructure, and Transport (MOLIT) will choose 13 central-city-area-type projects, 2 economic-base-type projects, and 10 public-company-proposal-type projects among the numerous projects from 16 local governments while each government can apply only 4 projects, respectively, for the 2017 Urban Regeneration New Deal project. If MOLIT selects only those projects with a project effect maximization purpose, there will be unselected regions, which will harm the balance of regional development. For this reason, an optimization model is proposed herein, and a combinatorial optimization method using the GA and B&B methods should be sought to satisfy the various constraints with the object function. Going forward, it is expected that both these methods will present rational decision-making criteria if the central government allocates a special-purpose-limited budget to many local governments.

  • Purpose: The present study aimed to evaluate the influence of how the trauma care system applied on the management of trauma patient within the region. Methods: We divided the patients in a pre-trauma system group and a post-trauma system group according to the time when we began to apply the trauma care system in the Halla Hospital after designation of a trauma center. We compared annual general characteristics, injury severity score, the average numbers of the major trauma patients, clinical outcomes of the emergency department, and mortality rates between the two groups. Results: No significant differences were found in the annual patients' average age ($54.1{\pm}20.0$ vs. $52.8{\pm}18.2$, p=0.201), transportation pathways (p=0.462), injury mechanism (p=0.486), injury severity score (22.93 vs. 23.96, p=0.877), emergency room (ER) stay in minutes (199.17 vs. 194.29, p=0.935), time to operation or procedure in minutes (154.07 vs. 142.1, p=0.767), time interval to intensive care unit (ICU) in minutes (219.54 vs. 237.13, p=0.662). The W score and Z score indicated better outcomes in post-trauma system group than in pre-trauma system group (W scores, 2.186 vs. 2.027; Z scores, 2.189 vs. 1.928). However, when analyzing survival rates for each department, in the neurosurgery department, in comparison with W score and Z score, both W score were positive and Z core was higher than +1.96. (pre-trauma group: 3.426, 2.335 vs. post-trauma group: 4.17, 1.967). In other than the neurosurgery department, W score was positive after selection, but Z score was less than +1.96, which is not a meaningful outcome of treatment (pre-trauma group: -0.358, -0.271 vs. post-trauma group: 1.071, 0.958). Conclusions: There were significant increases in patient numbers and improvement in survival rate after the introduction of the trauma system. However, there were no remarkable change in ER stay, time to ICU admission, time interval to emergent procedure or operation, and survival rates except neurosurgery. To achieve meaningful survival rates and the result of the rise of the trauma index, we will need to secure sufficient manpower, including specialists in various surgical area as well as rapid establishment of the trauma center.

  • Rural tourism is considered one of the main components of travel today. This may explain the emerging interest in tourist behavior at rural sites. Nevertheless, it can be argued that research on tourists' motivation as well as segmentation for visiting rural sites is still in its infancy. The purpose of this study has three main objectives: (1)to adjust the motivations of rural tourism to the general motivations for all travelers and find the core factors for rural tourists. (2)to show the segmentation of korean rural tourists, and (3)to suggest the characteristics of rural tourists' typology. This paper was conducted through two studies: a literature review and a survey for empirical exploration of the ideas. The empirical data are extracted through convenience, and the valid questionnaires totaled to 828. The Frequency, Descriptive, Factor, Cluster, Discriminant, Cross-tabulation analysis were used for the data analysis. The results of analysis indicate that the rural tourists' motivation is consisted of 14 factors. the key elements play a major role in rural tourism. and the rural tourists' market was divided into 5 different groups. The results of this study will not only contributes to a better understanding of rural tourism due to clarification of tourist motivations but also have implication for the development and management of rural sites.
