The aim of this paper is to analyze the changes in the travel pattern of public transit users, service satisfaction before and after public transportation system reform in Daegu. For this purpose, we conducted a survey of people on public transit users and the results of study are as follows : First, it was found that transfer trip had increased, especially concerning the changes of travel pattern from bus trip to the transfer trip between the bus and subway. Because it makes a financial sense to transfer based on free charge transfer system. Secondly, the transfer satisfaction was improved for public transit users, but they are still reluctant to use transfer system.

최근 자동차 수의 급속한 증가와 대중 교통의 발달로 인하여 ITS(Intelligent Transportation System)과 같은 지리/교통 안내 시스템의 연구 개발이 활발히 이루어지고 있다. 이러한 시스템의 중요한 기능 중의 하나로 대중 교통의 관리와 안내 서비스가 있다. 특히 우리나라의 경우 아직 많은 사람들이 대중 교통을 이용하고 있고, 대중 교통이 대도시 교통체증의 중요 해결책으로 인식되므로 이러한 기능이 더욱 필요하다. 본 논문에서는 인터넷을 통하여 접근할 수 있는 버스 노선 안내 서비스 시스템을 개발한 경험을 소개한다. 버스 노선 안내 서비스 시스템은 사용자가 접근하기 용이해야 하며 실용적인 서비스 결과를 제공할 수 있어야 한다. 또한 추후 개발되는 여러 ITS 구성 요소들과 유기적으로 결합할 수 있는 상호 운용성이 필요하다. 본 논문에서는 분산 객체 미들웨어의 표준인 CORBA를 이용하여 인터넷을 통한 접근이 용이하고 상호 운용성이 뛰어난 시스템 구조를 제안하였다. 이 시스템의 구조와 스키마는 추후 다른 대중 교통 안내 서비스 시스템과의 연계 혹은 다른 ITS 구성 요소와의 연계에 쉽게 대응할 수 있을 것으로 기대된다.

멀티미디어 시대로의 진입에 따른 인터넷에서의 실시간 데이터 전송을 위한 어플리케이션의 요구에도 불구하고 현재의 인터넷은 최선형 서비스만을 제공할 뿐 QoS(quality of service)를 제공하지 못하고 있다. 이에 인터넷 표준화 기구에서는 종합서비스(IS : integrate service)모델을 정했다. 〔5〕 그러나 기존의 shared LAN 환경에 이를 적용하기에는 자원의 공유로 인한 어려움이 있다. 반면. 직렬 버스의 표준으로 자리잡은 IEEE 1394 고속 직렬 버스〔1〕〔2〕는 예약된 대역폭을 보장할 수 있을 뿐만 아니라 고속통신이 가능하여 IS 모델의 적용에 적합한 기술이라고 할 수 있다. IS over 1394 프로토콜〔8〕은 IS 모델을 IEEE 1394 고속 직렬 버스에 적용하기 위한 프로토콜로써 본 논문에서는 이의 구현을 위한 구조를 고찰하였다.

메타버스 시장은 향후 지속 성장할 것으로 예상되지만 현재 메타버스 관련 이해관계자 중계 플랫폼은 부족한 실정하다. 따라서 메타버스 서비스 이해관계자간 연결 플랫폼을 개발한다면 개인, 소상공인, 그리고 중소기업 등 서비스 요청자들의 접근성을 높일 수 있으며, 이를 통한 부가가치 창출이 가능할 것으로 기대된다. 이에 따라 '메타드림(Meta Dream) 플랫폼'을 기획하고 개발하였다.

Most of the metaverse service is a gamification type of metaverse solution composed by placing 3D objects on a 360 panoramic world base. However, the metaverse webtoon service is lacking in implementation and research. In this study, a method for realizing a 2D flat image form in a 3D space and a realistic 360-degree panoramic webtoon metaverse service were studied. The research process consisted of basic storytelling and design work for webtoon production, panoramic image creation to convert the produced image into 360-degree form, and content creation process for viewing 360-degree directions. Finally, we implemented shading and material work with game engine tools so that you can enjoy virtual reality-based webtoons. The webtoon-based metaverse study studied the process of creating a 360-degree panoramic webtoon from content that can only be viewed in 2D format. Accordingly, it is thought that webtoons will also be presented as a standard for the production and implementation method for the metaverse service.

As public transportation use increases, studies are being conducted to consider user convenience using IoT data collected via the bus information system. A low-floor bus means a bus that is designed to be 20 cm lower than a normal bus and can be wheelchair-accessible. However, the system in which the transportation weak is provided to use the low-floor bus is less than the system provided to the general user. In order to use the low-floor bus smoothly, as in the case of the general user, the service system for the weak driver is needed. In this paper, a low - floor bus reservation system is designed to provide a service for low - rise bus users to conveniently use low - floor buses.

To raise transit ridership, it is necessary to expand transit facilities in long term Plans and to raise passengers' satisfaction by improving bus service qualify in short term Plans. In this study, the relationship between bus driver job satisfaction and Passenger service Performance is analyzed. The results of the study indicate that a driver s job satisfaction has an influence on accident rates. However, even when job satisfaction is not very high, if food resting facilities and Policies ave Provided then the Probability of an accident tends to decrease. To improve job satisfaction, several things should be done, such as stabilizing employment, creating fair company policies, improving overall employee welfare, and enhancing driver achievement from working. The satisfaction from salary is also an important factor and drivers are satisfied when they earn more money relative to other companies' drivers and when they aye satisfied with their salary increases. Therefore, creating appropriate monetary incentives would be a food policy for improving bus driver job satisfaction. This study serves as pilot research to make a foundation for further research about job satisfaction in the public transit field.

This study looked at how the digital cultural heritage, which is being actively built by the government and public institutions, can be utilized in the metaverse service. Through an expert interview, we investigated how the digital cultural heritage of Bulguksa can be serviced with the four elements of the metaverse: augmented reality, mirror world, lifelogging, and virtual world. As a result of the study, it was confirmed that when digital cultural heritage is used in a virtual space called metaverse, interactive and realistic services can be provided to users. In addition, it was found that users can exhibit, experience, and educate online parts that are not available in real life in the same situation as if they were in the field. Through this, it was confirmed that if digital cultural heritage is designed as a metaverse service, it can provide functions and services of a different level than before. In particular, the result was obtained that it is possible to provide services considering the characteristics of each of the four elements of the metaverse. First, it is possible to obtain the convenience of augmenting the senses by using augmented reality, and secondly, it is possible to obtain the scalability and efficiency of reproducing the real space by using it as a mirror world element. Third, by using the lifelogging element, communication can be strengthened through the user's record and connection, and fourthly, through the virtual world element, roles and activities in the virtual world can be given to the user. Therefore, if digital cultural heritage is developed as a metaverse service in consideration of these factors, a more active and open experience environment can be provided to users.

The bus transfer system has been extended from Seoul to Gyonggi province to provide better Seoul metropolitan area transit service in September, 2008. Moreover, the curved bus routes, except existing rapid bus routes, which cause longer travel time have been straightened out. Also, the Skip Stop operation suggested by passengers has been introduced to main stops in the newly added express bus lines. This study surveyed passengers service satisfaction for the recent adopted bus policies such as the transfer discount system and the express bus system in Seoul Metropolitan area. The survey results may be important foundation for future strategies for improvement. The survey included questionnaires about the importance and the satisfaction level on both quantitative and qualitative factors. The results were statistically analyzed by the modified IPA (Importance-Performance Analysis). As the result of the survey, the newly adopted services such as fare system, fare discount on transferring, travel time savings and increased number of stops are economically feasible and satisfactory, whereas the accessibility to stops, ventilation and air quality in vehicles are the priorities to be improved. Also, the safety and the information system is in need of improvement.
