The smart tourism service provides services such as travel planning and tour guides to tourists using key technologies of the 4th industrial revolution, such as the Internet of Things, communication infrastructure, big data, artificial intelligence, AR/VR, and drones. We are developing smart tourism services such as recommended travel products, my travel itinerary, tourism information, and chatbots for tourists through the smart tourism app. In this paper, we develop a smart tourism service system that provides real-time location-based tourism information and weather information to tourists. The smart tourism service system consists of a smart tourism app, a smart tourism information system, and an IoT data collection device. The smart tourism information system receives weather information from the IoT data collection device installed in the tourist destination. The location-based smart tourism service is provided as a smart tourism app in the smart tourism information system according to the Beacon's UUID in the IoT data collection device. The smart tourism information system stores the Beacon's UUIDs received from tourists and provides a safe hiking service for tourists.

소비자들이 이용하는 정보채널에 따라 소비자가 중요하게 평가하는 여행사 서비스품질 속성에는 차이가 있을 것이라는 문제의식을 가지고 본 연구를 진행하였으며 선행연구를 통해서 여행상품 구매자들은 무형의 서비스상품을 구매하기 위해서 다양한 정보채널을 활용해 여행사의 서비스품질을 평가하고 있으며 일반적으로 정보탐색에 이용되는 채널(인적채널, 영업장방문채널, 미디어 채널)을 통한 정보탐색 활동의 노력에 따라서 서비스품질속성에 대한 중요도 평가에는 유의한 차이가 있음이 나타났다.

To compute the expected travel time of storage and retrieval (S/R) machine in automated warehousing systems most of the previous studies assumed that equal number of rack openings are required regardless of the nature of storage assignment rules. It is known that randomized storage assignment rule usually needs less storage to space than needed for full turnover-based assignment rule. The objective of this paper is compute the expected travel time of each assignment rule more equitably by taking into account the storage space required for each rule. First, the rack storage space is determined which satisfies a given service level. Then based on the standard Economic Ordering Quantity model, trade-off analysis is carried out which relates the storage space to the expected travel time of the S/R machine. Finally, example problems are solved to compare the performance of each assignment rule under varying conditions of demand pattern and service level.

Express subway system is one of the effective systems adapting to improve service level. Express trains make fewer passenger stop, using a double track or a bypass track, than local trains which served all stations, Express service has been very popular with passengers who travel uninterrupted between terminals, but is has generated some dissatisfaction among passengers who experience longer waiting time on stations. This study aims at proposing the methodology to analyze changes of travel pattern in subway system adapting the express service and to estimate the time saving effects resulting from the installation of the express system. This methodology is evaluated in the fifth line under an assumpt ion that express subway system are adapted. Based on the results of the case study, the following conclusions are made: First, express system reduce a total travel time of 13% or above. Second, shorter headway of express trains increases the time saving effects on subway system. although it requests more waiting time to local train passenger. Third, an installation of Express system to Seoul subway system can augment subway demand in seoul metropolitan area.

Background: This study was purposed to analyze the effect of spatial accessibility to the psychiatry department in general hospital on the outpatient visit of mental patients. Methods: Data was provided from the Statistics Korea and Statistical Geographic Information Service, National Health Insurance Service, Health Insurance Review and Assessment Service, and Korea Transport Institute in 2015. The study regions were 103 administrative regions such as Si and Gu. The 103 regions had at least one general hospitals with a psychiatry department. The number of outpatient visit of mental patients in regions was used as the dependent variable. Spatial accessibility to mental general hospital was used as the independent variable. Control variables included such as demographic, economic, and health medical factors. This study used network analysis and multi-variate regression analysis. Network analysis by ArcGIS ver. 10.0 (ESRI, Redlands, CA, USA) was used to evaluate the average travel time and travel distance in Korea. Multi-variate regression analysis was conducted by SAS ver. 9.4 (SAS Institute Inc., Cary, NC, USA). Results: Travel distance and time had significant effects on the number of outpatient visits in mental patients in general hospital. Average travel time and travel distance had negative effects on the number of visits. Variables such as (number of total population, percentage of aged population over 65, and number of mental general hospital) had significant effects on the number of visit in mental patients. Conclusion: Health policy makers will need to consider the spatial accessibility to the mental healthcare organization in conducting regional health planning.

본 연구는 대구시 대중교통체계 개편 후 이용자 의식조사를 토대로 대중교통체계 개편 전후의 이용자 통행패턴의 변화 및 환승통행, 서비스 만족도에 대한 분석을 실시하였다. 그 결과 대중교통체계 개편으로 환승통행 수요가 증가하였으며, 특히 버스를 이용한 통행패턴에서 버스와 지하철간의 환승을 통한 통행패턴으로의 변화가 높은 것으로 나타났다. 이는 환승요금 무료할인제 실시로 환승에 대한 경제적 부담감의 감소와 버스노선체계 개편으로 대중교통이용자의 통행패턴이 다양화되었기 때문이다 환승에 대해서는 전반적으로 개선된 것으로 나타났지만, 무환승 희망비율이 높게 나타난 환승에 대해서는 여전히 많은 부담을 느끼는 것으로 나타났다

최근 철도 서비스를 개선하고자 기존선을 복선 및 전철화 하는 등 철도네트워크 기능강화사업이 활발히 추진되고 있다. 이를 배경으로 본 논문에서 급행철도와 같이 새로운 철도 운영서비스가 제공될 경우 타 교통수단으로부터 얼마의 전환수요가 발생될 것이며, 철도이용형태는 어떻게 변화될 것인지? 등 앞으로 건설될 대구권 광역철도를 대상으로 SP와 RP데이터에 의한 전환수요 예측방법의 적용성을 검토하였다. 모형 구축결과, 기존 SP와 RP데이터를 결합하는 동시적 모형과 순차적 모형이 모두 유용하여 총통행시간과 통행비용의 파라미터 추정치가 충분한 설명력을 나타내고 있으며, 동시적 방법이 보다 효율적으로 분석되었다. 특히 RP+SP의 결합모형의 타당성을 더욱 높이기위해서 RP데이터를 비례적으로 적용한다면, 철도요금과 통행시간 설정에 따라 전환수요를 쉽게 파악할 수 있을 것이며, 대구권 광역철도를 비롯하여 타 지역에서도 보다 실용적으로 적용할 수 있을 것으로 판단된다.

Purpose: This research aims to explore the effects of airline's pricing and service quality through service distribution process on repurchasing intention of the air passengers with meditations of passenger satisfaction and airline brand. Research design, data and methodology: This paper particularly focused on employing the moderating effect with two different market segmentations, namely leisure and corporate purpose travelers, in the Korean market. The total sample size of this research is 363 respondents of the general public in Korea. For the methodology of this research, structural equation modeling (SEM) was utilized for the statistical analysis. Results: It figured out that passenger satisfaction is ultimately the most important among variables of price, service quality and repurchase intention for both groups. On the contrary, the relationships, between price and airline brand in both groups, and between airline brand and repurchase intention in the leisure travel only, were not noted as beneficial effects. Conclusions: More noteworthy was that airline brand had a positive influence on repurchase intention in the corporate travel group. Based on this research, the results will deliver the contributions to the commercial airlines in the future.

A bus scheduling problem with multiple objective functions and travel time constraint is to determine the allocation of buses to customer service requests minimizing the number of buses and travel costs under the travel time restriction for each bus. For the scheduling, we first represent the scheduling problem using a graph and develop a hierarchical approach. Second, we develop a mathematical model based algorithm for the scheduling problem including heuristic methods. We tested the performance of the algorithm on instances with real data. As a result, the total number of buses and travel costs are reduced over about 10% comparing with that of current practice at the company.

이 논문은 혼잡현상을 갖는 교통체계의 사회비용함수를 사회비용 최소화문제로부터 도출하여 분석하였다. 이 논문은 이 분야의 기존 연구에서 다루지 않았던 다음의 두 가지를 중점적으로 분석하였다. 하나는 이용자들의 시간가치가 다를 경우에 비용함수의 구조가 어떻게 달라지는지를 검토하는 것이고, 다른 하나는 사회비용함수를 구성하는 공급자 비용함수의 구조를 파악하는 것이었다. 분석의 결과는 다음과 같이 요약될 수 있다. 첫째, 한계사회비용은 특정한 시간가치를 가진 고객이 소비한 시간가치비용과 추가 고객의 처리에 수반되는 시스템 전체의 서비스시간 증가에 따른 한계혼잡비용으로 구성된다. 둘째, 한계혼잡비용은 공급자의 보상한계비용과 같은 바, 후자는 공급자가 추가의 고객을 가장 경제적으로 처리함에 필요한 용량의 변경에 의한 서비스시간의 변화 양에 대한 이용자 전체의 시간가치를 보상해준다는 전제아래서의 공급자 한계비용을 지칭한다. 셋째, 보상한계비용은 서비스시간함수가 산출과 용량에 대해 동차함수일 경우 한계용량비용에 시스템 이용률의 역수를 곱한 값과 같다.
