차안에 탑재되는 차량용 헤드유닛은 AVN(Audio, Vedio, Navigation)에서 외부 기기 및 인터넷과의 연동을 통한 IT 융복합 서비스가 제공되는 차량용 인포테인먼트 시스템(In-Vehicle Infortainment, IVI)으로 진화하는 추세이다. IVI 시스템에서는 3G, WiFi, Bluetooth 등을 통하여 인터넷 접속이 가능하고, 이러한 인터넷 연결을 기반으로 다양한 인터넷 서비스를 제공할 수 있다. 이러한 인터넷 서비스 중 웹 저장소 연동 응용 서비스는 사용자의 다양한 단말들간에 콘텐츠를 공유할 수 있도록 하는 서비스이다. 웹 저장소 연동 응용에서는 사진/음악/동영상/문서들에 대하여 서버와의 접속을 통해 공유할 수 있는 기능을 제공하며, 이러한 응용이 사용되는 장소가 차량 안이다 보니, 운전에 방해가 되지 않는 사용자 친화적이고 직관적인 인터페이스를 제공해야 한다. 이러한 요구사항들을 충족하는 차량용 웹 저장소 연동 응용프로그램에 대하여 제안하고자 한다.

개인 차량을 유지하기위해 지불해야 하는 것으로 차량구입비용, 보험료, 자동차세, 차량정비 비용 등 그 규모가 만만치 않다. 그러다 보니 한 대의 차를 여러 사람이 시간을 쪼개어 활용하면 더 효율적이겠다는 생각을 하는 사람들이 생겨났고, 그래서 생겨난 새로운 자동차 이용방법이 카셰어링이다. 카셰어링은 원하는 시간에, 원하는 만큼, 필요한 최소의 금액만을 지불하는 자동차에 대한 현명한 소비를 하는 하나의 방법이 될 것이다.

The study explores the way how sharing economy services of accommodation and car rental, one of social issues actively discussed today are settled in the process of sharing economy building in local destinations. The result shows that average consumers expressed their favorable attitude toward the sharing economy services. However, the consumer's attitude didn't directly affect the consumer's positive perception that there is need for local sharing economy service network and the educational system for local residents and the network helps the economy. Instead consumer's knowledge of sharing economy services and their eagerness to learn the knowledge as parameters related the consumer's attitude to their perceptions; the consumer's attitude affected indirectly their perceptions. The study shows that local communities and their residents' efforts are not enough simply to activate the sharing economy services in the development process of tourist resources, while it asks consumers to learn information and knowledge of the sharing economy. Therefore, consumers and residents should interact and communicate closely with each other to help the development of local destinations and tourist resources based on sharing economy.

The Traffic congestion is caused by the increasing traffic demand. Thus, economic losses have been increasing every year. To solve these problems, car sharing and rental car systems that are equipped with IT technologies emerge. Car sharing has many advantages-the alleviation of the traffic congestion, the saving of maintenance cost for cars, the reduction of car possessiveness, the solution for the hassle of car ownership, for business and personal duty, and the improvement of connectivity between public transportations-. The goal of the car sharing is to achieve low-carbon and eco-friendly transportation. In this study, we review papers related to the car sharing system and the cost system of traffic systems. We estimate the optimal cost of the cloud traffic system that is one of the car sharing services. We suggest a methodology to estimate operational cost and use cost through the analysis of cost system between similar traffic means. The range of the maximum and minimum cost was determined through the comparison and analysis of similar traffic means. Expected demand and the cost that people are willing to pay were estimated through optimized value pricing. The minimum cost per hour that was compared to the cost of rental car was estimated at 5,333 won and the maximum cost per hour that was compared to taxi cost was estimated at 17,700 won. The cost for users was estimated at 6,930 won. The cost of 50% demands was estimated at 6,550won. Future studies should analyze service hours of users, weather, demand pattern and trend and consider them into the cost estimation.

Mobility service is a service that connects consumers and suppliers of transportation using information and communication technology (ICT), and aims to reduce inconvenience to users in the current transportation system and increase environmental sustainability. Recently, the use of mobility services is gradually increasing, and interest in it from academia and industry is growing. This study derives key influencing factors related to the increase in intention to use vehicle mobility services, and comparatively analyzes the influences between groups by service type (car-hailing vs. car-sharing services) and by generation (generation MZ vs. generation X). As a result of the comparative study, there were differences in user benefits between service type groups, and differences in user benefits and attitudes toward mobility platforms between generation groups. Through this comparative study, the main factors affecting the increase in the intention to use the vehicle mobility service by generation and service type and their differences were identified. This study provides implications to consider in terms of knowledge management for activating vehicle mobility services according to the major target users and service types.

People's leisure activities have increased due to changes in perception of social life. Camping cars are becoming popular due to the development of camping culture and traveling. However, there are not many users compared to the population of the camper due to the difficulty of economy and usability. Making it not easy to purchase or rent a camping car. Therefore, this study researches on camping service by combining shared services. It is aimed to provide a user centered camping shared service considering usage and economic efficiency. This study analyzed the concept, characteristics and current status of shared service and camping car with reference to domestic, overseas literature and internet data to provide basic data of camping car using shared service. In addition, through case study of shared vehicles, it is possible to grasp the current market. Integrate P2P, B2C, renting company and individuals to derive the design of A2P (All to People)service which connects and shares all. The user can have its own space available at the desired place and time. This study is a camping or unique mobile space service design that can be easily experienced in everyday life. It will reduce the strain of maintaining expenses and also process of pick up, return is freely making user-centered service design. This service design will lead to a diverse range of leisure activities and contribute to the upsweep of the camper industry.

This paper proposes a reliable data sharing scheme on the internet of vehicles (IoV) by utilizing blockchain technology for constructing a decentralized system approach. In our model, to maintain the credibility of the information messages sent by the vehicles to the system, we propose a reputation rating mechanism, in which neighboring vehicles validate every received information message. Furthermore, we incorporate an incentive mechanism based on smart contracts, so that vehicles will get certain rewards from the system when they share correct traffic information messages. We simulated the IoV network using a discrete event simulator to analyze network performance, whereas the incentive model is designed by leveraging the smart contract available in the Ethereum platform.

미국, 유럽에서는 315MHz, 433.92MHz를 아마추어 무선국과 공유하여 차량용 주파수로 활용하고 있다. 참고로, 미국 고속도로 안전위원회는 TPMS(Tire Pressure Monitoring System)를 2003${\sim}$2006년 까지 미국 내 생산 차량 및 수입차량에 대해 TPMS 센서 장착을 100% 의무 적용하고 있다. 433.92MHz는 국내에서 이미 아마추어 무선 업무용 주파수로 할당되어 사용되고 있으며, 현재 TPMS 수입차량의 국내 도입을 위한 주파수 분배 및 기술 기준이 마련되어 있지 않은 상황이다. 향후 해외 수입차량의 국내 도입 및 국내 차량의 해외 수출을 고려할 경우 국제 기준에 부합하면서 국내 전파환경에 적합한 주파수 분배 및 기술 기준의 마련이 필요하다.
