모바일 환경이 발전하고 보편화됨에 따라 사용자의 상황정보를 인식하고 추론하여 서비스를 제공하는 상황인식 서비스에 대해 관심이 높아지고 있다. 상황인식 서비스는 사용자 및 주변 환경의 상황을 알아내고 공유하여 그에 맞는 서비스를 제공한다. 이를 위한 상황정보는 사용자의 요구와 주변 상황이 수시로 변화하는 이동통신 환경에서 중요하게 활용된다. 본 논문에서는 컨텍스트의 수집과 공유를 위해 안드로이드 기반의 컨텍스트폰 플랫폼과 컨텍스트 서버를 구현하여 사용자 상황 정보를 시각화 하고 서로 공유할 수 있게 하였다. 상황인식에 대한 연구에는 주로 위치 및 이동에 관한 연구가 많은 부분을 차지하고 있는데, 위치정보는 상황인식을 위해 반드시 필요한 정보이며 이를 통해 사용자의 현재 상황을 파악할 수 있는 중요한 정보로 활용되고 있다. 안드로이드 기반의 컨텍스트폰 플랫폼과 컨텍스트 서버, GPS를 이용하여 사용자의 위치를 추적하거나 찾아내어 실시간으로 상대방의 위치 정보와 사용자 간의 거리를 알아내어 공유하고 맵을 통해 사용자 위치를 파악하여 위치와 관련된 서비스를 제공하려 한다.

인터넷에서 서버 컴퓨터를 거치지 않고 정보를 찾는 사람과 정보를 가지고 있는 사람의 컴퓨터를 직접 연결시켜 데이터를 공유할 수 있게 해주는 가상의 공유 시스템인 P2P(peer to peer)는 개방 시스템이기 때문에 근본적으로 보안상의 문제점을 안고 있다. 이러한 보안상의 문제점을 해결하기 위한 한 방법으로서, JXTA를 통한 P2P 어플리케이션 구현을 제안하고자 한다. 따라서 안전한 P2P 어플리케이션 개발을 위하여 JXTA 플랫폼 구조와 보안 기술을 분석하였고, 어떻게 JXTA가 플랫폼 레벨에서 주어진 암호학적 툴킷을 사용하여 보안을 다루지를 연구하였다.

Recently, consumers are increasingly interested in the sharing economy, which utilizes various resources by sharing unused or under-used products/services with others. This study focuses on Airbnb, a representative sharing economy platform, to identify the success factors of the sharing accommodation services. The key properties of sharing accommodation services are extensively surveyed from extant literature and are classified them into the three important factors (economic, convenience, and trust) that influence the success of room-sharing services. The research data include 1,673 Airbnb hosts who offered accommodations in New York City, USA, in June 2018. The research variables of economic-, convenience-, and trust-related factors are utilized in the empirical analyses. The results of this study show that the number of available facilities, flexibility of refunds, the response rate and time to customer requests, and the status of Super host are positively associated with guest satisfaction from sharing accommodation services. This study bears significant managerial implications by suggesting a set of practical guidelines to participants in sharing accommodation services.

This study aims to discuss the current status of the ride-sharing platform industry, which embodies the core values of the 4th Industrial Revolution, sharing and connectivity, as well as economic, industrial, and legal issues. To understand the position of competing groups, the research conducted extensive literature reviews on domestic and international cases of technical and legal issues of the sharing economy. The result indicates that the ride sharing industry showed the economy of synthesis in which production, supply, distribution, and consumption are on one platform. It made possible to share values to users and synthesize them with new services through easy-access mobile application technology. To resolve the conflicts between the taxi industry and the ride sharing industry, this study suggests the following: Ride-sharing companies should make contributions to provide legitimate services. The taxi industry needs to understand the value of the new industry and consumers who chose the shared platform service. The significance of the current study is that it proposed a comprehensive analysis and policy direction toward the issue of balance between public and private interests and legal stability.

People can easily use a shared economic service system based on ICT technology. Most of the shared economic services are provided by private companies, and discussion on public goods is insufficient. If we look at the current shared economic service from the point of view of courier service, $\ddot{U}ber^{\prime}s$ system can be an alternative. The post office courier service uses ICT technology but differs from the service of the shared economy. This study uses Delphi analyzer method and AHP methodology to derive important factors in introducing shared economic system. As a result, socioeconomic characteristics were found to be the most important in the upper tier, and the shared economic platform, sharing of idle resources, popularization of smartphone, and increase of e - commerce were the four important factors in the lower tier. In order to maximize efficiency, which is the essence of the shared economy, the necessity of introduction into the shared economic system and important factors in the introduction of public goods are presented.

As the sharing economic market grows, the subject of sharing is expanding to intangible resources such as time, experience, and expertise. The phenomenon that an individual temporarily participates in the platform by utilizing own intangible resources is defined as a 'gig economy'. The gig economy has a positive expectation that can create new jobs, but also has negative warnings that it is only a temporary job based on low wages. The gig economy market is growing rapidly in Korea, however there are very few academic discussions. This study examines the experiences of resource providers in the Korean gig economic platform, and then explores future job changes based on the perception of resource providers. This study selected the subject of research as a talent sharing platform and conducted in-depth interviews with 16 resource providers. The results of the research were presented through content analysis, and their experiences and perceptions were classified into six themes. This study implies academic and practical significance in exploring in depth the overall experience of resource suppliers and in suggesting proposals for desirable successful market growth.

As part of the sharing economy service, the present study is not only about the positive aspects of O2O services, but also about the consumer ethical perceptions of recent conflicts with existing business and labor markets, trust of platform, and service utility on consumer satisfaction and intention to recommend O2O services. To test hypotheses, data were collected and analyzed for 149 samples, focusing on the car sharing service, an example of the sharing economy service, which is becoming an issue. As a result, the ethical self-identity of the consumer, the trust of the platform, and the service utility, all affected the service satisfaction, whereas only the hedonic utility and trust of the platform had a positive effect on the intention to recommendation. This study is meaningful in that it examines the influence of service utility focusing on ethical consciousness and social perspective of consumers, rather than on the point of consumption such as ethical consumption position and trust of platform based on sharing economy service.

As smart home network services such as home CCTV, outdoor control of home appliances, home security and disaster prevention services become popular, there appear various affiliated products including smart home gateway and smart speaker. Since those services are generally developed on the vendors' individual hardware and software platforms, it is not much expected for them to interwork well among different architecture and communication methods. In this paper, we propose a new home network service system running on an open source platform to address such issues. We implemented a home network system using OpenWRT-based wireless router(or access point) and Zigbee communication technology. In the proposed system, a wireless router replaces a commercial home gateway and small control units implemented with Arduino control electronic devices and sensors in home. Several service scenarios are also implemented to verify the operability of the proposed system.

As data is evaluated as a key asset for digital transformation, efficient and stable management of data, smooth sharing data, and provision of services using data are also required in the defense. To support this, the Korean military is laying the foundation for the Military Artificial Intelligence Platform which is a defense data management infrastructure. In this paper, we examine the data strategies and data platform promotion directions of Korea and major advanced groups, and we look for suggestion and present the direction of development of the Military Intelligent Platform. We are expected that it can contribute to the establishment of a safe and efficient defense data management infrastructure for the Korean military.
