Purpose: This study aims to investigate the national obligation of public health support for residents in medically vulnerable areas in Korea, and to propose a suitable model for public health institutions in this region. Research design, data, and methodology: A survey targeting residents was conducted from August 10 to August 17, 2021, with a sample size of 177 general citizens. The survey utilized a structured questionnaire administered online through Google, employing convenience random sampling. After an editing process to ensure data accuracy, the final dataset of 174 valid samples underwent encoding, coding, and cleaning using the IBM SPSS Statistics 22.0 program for analysis. Results: Health status revealed a moderate level, and 63.8% reported having chronic diseases, particularly prevalent among the elderly. External healthcare institutions were commonly utilized, with proximity and competence of doctors being primary reasons. Respondents expressed a need for improving the public health and medical system, emphasizing the establishment of a County Health Centre and expanding medical departments. Conclusions: In this region, the region's unique challenges, including education, employment, population decline, aging, and transportation, require multidimensional efforts and urgent intervention by public entities. Long-term strategies involve considering the establishment of a health and medical institute, adjusting health centre resources to local realities, and fostering a cooperative system for collaboration among residents and institutions.

The ridership and transit systems are influenced by the expansion of metro-rail in Seoul metropolitan area. However, it has been difficult to measure its precise quantitative influences. Also effective policy implementations have been limited due to the lack of practical evidences. Thus an empirical analysis for an operating metro-rail is essentially required. In this regard, this study examines the impact of the Jungang line on transportation system, whose metro-rail block has been recently started new service. The main interest of this study is to find out the changes of ridership and to forecast the ridership changes by the metro-rail service. The results indicate that the effect on auto users is less than that of bus users. The auto demand is decreased by 33.3% and the bus demand by 66.6%. Additionally, its influence on Gyeonggi-do bus was greater compared with that on the Seoul bus. From questionnaire survey, this results could be confirmed. To sum up, the metro-rail gives less influences on auto users, while it gives greater influences on bus users.

A tram has been the focus of a new public transportation that can solve a traffic jam, decreasing of public transit usage and environmental problem in recent years. This study aims to develop a signal optimization model for considering the traffic signal progression of tram and vehicles, when they are operated simultaneously in the same signalized intersections. This research developed the KS-SIGNAL-Tram model to obtain a minimum tram bandwidth and to minimize a vehicle's delay to perform a tram passive signal priority, it is based on the KS-SIGNAL model and is added to the properties of a tram and it's system. We conducted a micro simulation test to evaluate the KS-SIGNAL-Tram model, it showed that the developed optimization model is effective to prevent a tram's stop on intersection, to reduce a tram's travel time and vehicle's delay.

Gyeonggi-do comprises several types of areas, including urban, semi-urban, and rural areas. The availability of public transportation services varies depending on the area types, but the fare structure is based on a simple transfer rule, i.e., a transfer is free when completed within 30 minutes. As a result, users in non-urban areas with a poor frequency of public transportation services do not receive transfer discounts because most of the bus routes in these areas have a gap of more than 30 minutes between services. In terms of equality of opportunity, the transfer rule is being applied unfavorably and, as a result, equality of opportunity of the non-urban commuter is severely affected. Therefore, this study analyzed the user benefits mainly stemming from transfer fares using the smart card data of commuters using public transportation in Gyeonggi-do. An index called the beneficiary rate of the free transfer was developed and a scenario analysis was conducted based on the various levels of the rate. The results of this analysis proved that the users of public transportation services in non-urban areas in Gyeonggi-do can only receive transfer benefits by the extended time for free transfer and not by the implementation of a uniform policy irrespective of the type of area. The study also suggested an equitable fare transfer system and policy alternatives.

An urban transit is representative public transportation which lots of people take everyday. Especially, the station of urban transit is one of the very important public civil infrastructures. From the teachings of subway fire disaster occurred at Daegu on 2003, a certain incident might create large numbers of deaths or injuries and a lot of damages to the subway station without having an accurate grasp of emergency situation and doing proper action on the situation. Therefore, the passive surveillance system, which means the present CCTV based system, needs to be changed into the active one. The active surveillance system is the CCTV based system with intelligent softwares which affords to prevent a certain incident or trouble and its aggravation. In this paper, the state of the art of the representative companies developing intelligent softwares and its application sites of Australia and Hong Kong are briefly introduced. Finally, with the consideration of its recent trends, some technical contents for the intelligent surveillance system of domestic urban transit are briefly described.

Travel time reduction benefit is the most important benefit item in the feasibility study of transportation infrastructure investment projects and calculated by using the value of travel time. The current feasibility study guideline (5th edition) calculate the value of non-business ravel time in a metropolitan area, using the ratio of the value of non-business travel time to business travel time calculated based on the nationwide inter-regional traffic survey data of 1999. The characteristics of metropolitan trips are different from those of nationwide regional trips. Metropolitan trips have frequent transfers between multiple public transits and long-time commuter trips. Therefore, this research aims to calculate the value of travel time reflecting traffic characteristics in a metropolitan area by improving the limitation of current calculation methods. To reflect these characteristics, this research extracts commuter trips from non-business trips and calculates the value of travel time for commuter trips. The results of the likelihood ratio test for the commuter trip model and the non-business trip model are found to be statistically significant. An integrated public transportation model was also estimated in this study to reflect the trip conditions of the Seoul metropolitan area integrated fare system. The results of comparing coefficients between bus and subway in the integrated public transit model indicated that there were no statistically significant differences between the two modes.

The existing K-CASH system doesn't allow compatible between different regions, different public transportations and the technologies made by different operators. If a K-cash user wants to use public transportation charged not by K-CASH but other operator, then he or she would have to get other type of card available for that transportation. Also, the incompatibility of the existing K-CASH might cause unnecessary expense because similar systems would have to be doubly constructed if the K-CASH operator would like to install the K-CASH system on the same infra as the other operators already did. As a result, a system which allows people to use just one card for their convenience regardless of regions, types of transportation and operators has been strongly demanded. In this paper, we developed Nation-wide Interoperable K-Cash system, Nation-wide Interoperable K-CASH Card, Purchase terminal, Purchase SAM and Settlement system that were updated from the existing K-CASH system. And we performed a conformity test to confirm performance. Also Korea Financial Telecommunications & Clearings and the KORAIL NETWARKS and the HiPlusCard joined for the testbed in Gwangju for 6 months. This result of testbed finally proved that the Nation-wide Interoperable K-CASH system is completely compatible.

The existing city which consists of the downtown in Korea has been built spontaneously, and it is in difficulties for the distribution problem and traffic congestion since undersupply of social facilities cannot afford to handle the increasing traffic demand. So the traffic facilities have been reinforced to increase the competitiveness of the city and solve the related problems. The need of a new transit system considering the transport capacity and environment-friendliness is emerging as revitalization of public transportation is needed for reduce of personal transportation. In case of local governments that the Self-Reliance Ratio of local finance is high, if they promote the business by tram transit low which period could be shorten, it can correspond the traffic policy and invigorate the introduction of the new traffic system.

Analyzers adopt a variety of techniques in analyzing public policy. Based on the results of exploration, they explain problems and suggest prescriptions such as policy alternatives. By doing so, however, they have different degree of confidence in their own results according to what techniques they adopt. This study explores whether system dynamics apporach gives analyzers more confidence on their own simulation results than other approaches do. This study designed an experiment. Three research teams are organized. Each of them applies different analytic techniques on the same policy issue, i.e., introduction of transportation tax. It flnds that researchers using S,D. simulation technique are most confident on what they predict, while researchers adopting survey techniques show moderate degree of confidence on their results. Researchers using regression are least confident.
