This paper introduces TIGS(Touring Information Guidance System) which provides information with faster access time than the human service. This system is designed specifically for a traveler. This TIGS provides tourists the informations such as destination, current map information, touring courses according to schedules, and lodging information. Furthermore, this system is implemented with touch screen for the user to apply easily. The presented shortest path algorithm using duality theory is applied to schedule the touring courses to reduce the time and the cost. The used map is raster manner instead of vectorial manner to provide user convenience. If this developed system should be established in the public space such as station, airport, and bus station, the useful touring information can be provided the tourists. This system can be easily applied to different local area.

정보서비스의 기본목적은 신속 정확하게 최적의 정보를 이용자에게 제공하는 것이며 이러한 목적을 달성하기 위해 다양하고 효과적인 서비스 방법을 적용하려는 노력이 계속되어 오고 있다. 이러한 맥락에서 본다면 정부 정보소재 안내 서비스(GILS)는 공공부문 정보자원의 특성을 가장 정확히 파악하여 이에 대한 정보를 가장 효과적으로 제공할 수 있는 방안이라고 할 수 있다. 1998년 서비스를 시작한 '한마당'은 GILS를 기반으로 하여 구축된 시스템으로 국내의 공공기관 정보자원의 소재정보를 파악할 수 있는 창구로서의 역할을 수행하고 있다.

This paper introduces TIGS(Touring Information Guidance System) which provides information of the southwestern area of korea with faster access time than the human service. This system is designed specifically for a traveler. This TIGS provides tourists the informations such as destination, current map information, touring courses according to schedules, traffic information and lodging information. furthermore, this system is implemented with touchscreen for the user to apply easily. The shortest path algorithm is applied to schedule the touring courses to refute the time and the cost. The map is raster manner to represent southwestern area of korea instead of vectorial manner. If this developed system should be established in the public space such as station, airport, and bus station, touring will be more comfortable, the total income will more increase. Also, this system can be easily applied to different local area.

Metro stations are public places used by many people. If they use the station frequently, there is no struggling to find a way. But the first tourists or foreigners to visit are facing finding difficulties because of errors of the complicated sign and information. This study is the guidance of the metro station sign to provide effective information system and the research on the design improvement of metro station. In the first survey for this study I proceeded research about the concept of sign systems in metro station and literature search. In the second survey, I researched needs of the problems of the metro station users. In the third survey, I investigated Busan Metro Station's problems and design to improve the guide sign. In the survey results, users had a lot of difficulties in finding information because systematically increasing amount of information and guidance of the metro station. People can't find information because of sign indiscreet commercial advertising. Also they can get false information from sign without unity. To deal with these problems the metro station needs to improve design for a second-class citizen and refrain commercial advertising and design for information transfer capability.

This paper presents a context-aware information service system in public places that have complex processes, for the disabled and the elderly. The system infers context of a user which is derived from the user's demand, then it informs to the user -what to do, where to go-according to the context. Our system gets user's context from sensor data and informations from the local information system. The system provides more suitable information with a knowledge model, which organizes location and process data coordinately. The information is provided personally to the user, with mobile devices.

공공도서관은 모든 사람에게 평등하게 서비스를 제공해야 하는 기관이기 때문에 시각장애인과 같은 도서관 이용에 불편을 겪는 사람에게도 도서관 이용을 위한 서비스를 제공하여야 한다. 그러나 오늘날 우리나라의 도서관은 시각장애인등 도서관 이용에 불편을 겪는 사람들을 위한 서비스는 거의 존재하지 않으며 장애인이 아닌 정상인을 위한 공간으로 인식되어 왔다. 본 시스템은 NFC태그를 이용한 도서관 안내 시스템으로 책의 위치정보를 책과 책장에 부착된 NFC태그를 이용하여 읽어들이고 책의 위치정보를 음성으로 사용자에게 제공함으로써 도서관을 이용할 때, 책을 검색하고 금방 찾는 것이 힘든 시각장애인의 실정을 개선하고자 하였다. 또한 도서관에서 책을 찾는데 필요한 모든 정보들을 음성으로 사용자에게 제공해 시각장애인이 주위사람들의 도움 없이 언제든지 혼자서 도서관을 이용할 수 있도록 설계하였다.

In this paper, we design and implement a product information guidance system Based on BLE beacons. This system is designed to provide various functions such as contactless entrance service through mobile ticket, seat guidance service, event push service, content push service, and public service. This system consists of three modules: a beacon recognition module, a server linkage module, and a content transmission module. The beacon recognition module implements a function of transmitting a specific ID of a nearby beacon when a customer with a smartphone approaches the available service area. The server linkage module recognizes the beacon ID value, transfers it to the server, and implements the function to check the location of the server having the ID. The content transmission module implements a function of transmitting event or service information set at a corresponding location to a smartphone. The beacon-based product information guidance system implemented in this paper has the advantage of being able to quickly and easily implement various product information guidance systems.

Recently, analysis techniques to extract new meanings using big data analysis and various services using these analysis techniques have been developed. Among them, the transport is one of the most important areas that can be utilized about big data. However, the existing traffic route guidance system can not recommend the optimal traffic route because they use only the traffic information when the user search the route. In this paper, we propose a realtime optimal traffic route guidance system using big data analysis. The proposed system considers the realtime traffic information and results of big data analysis using historical traffic data. And, the proposed system show the warning message to the user when the user need to change the traffic route.

조달청이 입찰자 정보를 분석해 불법전자입찰을 색출해내는 '불법전자입찰 징후분석시스템'을 본격 가동한다. 조달청(청장 권태균)은 지난 7월 22일 "아직도 일부 입찰자들이 전자입찰시스템을 악용, 담함 및 공인 인증서 대여 등의 불법입찰 행위를 하고 있다"고 지적하고 "이를 체계적이고 상시 감시하기 위한 불법전자 입찰 징후분석시스템(이하 '징후분석시스템')을 본격 가동해 불법입찰 혐의가 짙은 201개 업체를 공정거래 위원회에 조사요청 할 계획"이라고 밝혔다. 이번 '징후분석시스템'의 본격가동으로 인증서 대여를 통한 불법전자입찰 행위를 뿌리 뽑아, 국가예산의 낭비방지 및 공공공사와 조달물품의 품질 제고에 기여할 것으로 기대된다.

Recently, people have come to enjoy using movies and music applications, such as YouTube, Netflix, and Watcha Play, on their smart devices while riding public transportation. However, they sometimes miss their destination stations because of these activities. Therefore, in this paper, we propose a disembarking notification system for public city buses using smart devices and high frequencies generated via the buses' speakers. The high frequencies are generated by the public buses' station information broadcasters. Smart devices then analyze the high-frequency signals with their inner microphones, and the proposed application displays a disembarking notification to the user when the user's destination or stop-over station's signal is the same. To evaluate this system's performance, we tested 1,000 real-time disembarking notifications, and the test results showed 98.9% accuracy. Moreover, we compared these results to those using only OpenAPI, and our proposed system featured far better outcomes. Thus, this proposed notification system can prove a useful technology for many people who often use public city buses, as it can notify specific users of their destination stations. Furthermore, this system will become innovative technology for global public transportation by informing users of their desired stations using speakers.
