PDA를 이용한 무선통신 단말의 구성은 이동성, 편리성이 강조되어야 하며, 언제 어디서나 사용자가 원하는 정보를 받아 볼 수 있어야 한다. 이러한 필요성에 의해 정보를 자동으로 다운로드(download)한다면 사용자의 편리성은 더욱 증대될 것이다. 따라서 PDA용 소프트웨어를 개발할 때 필요한 구성요소로서 무선 에이전트(wireless agent)개념을 추가하여 소프트웨어 계층을 구성하면 별도의 소프트웨어 개발단계 없이 무선 에이전트가 추가된 소프트웨어를 쉽게 구성할 수 있다. 본 논문에서는 PDA를 위한 소프트웨어의 에이전트개념을 도입하고 무선이동단말기의 이용효율과 편리성을 극대화하고자 무선 에이전트 클래스를 설계하고 구현하였다.

페리는 도서지역과 도시를 연결하는 중요한 교통수단이다. 최근에는 섬 관광, 낚시객 등이 늘어나면서 페리터미널을 이용하는 이용객이 증가하고 있다. 그러나 차량과 여객을 함께 탑승하는 페리(차도선)가 접안하는 페리터미널이 이용객 관점에서 이용에 편리한지에 대한 연구는 미비한 실정이다. 이에 본 연구에서는 많은 섬을 연결하는 도서항로가 위치하고 있는 목포지역을 대상으로 심층 설문조사(Audit survey)를 실시하여 페리터미널 이용객의 보행 편리성에 대하여 연구하였다.

개인이 실시간 방송을 할 수 있는 개인방송은 게임, 스포츠, 교육을 비롯하여 시대의 흐름을 고려한 요리, 다이어트 등과 같은 광범위한 미디어 콘텐츠를 생산하고 있다. 최근에는 실감형 콘텐츠를 위해 360도 카메라와 이를 마우스, 터치스크린, 자이로센서를 이용하여 제어하는 방식들이 소개되고 있다. 하지만 이러한 기술들을 활용해 더 많은 콘텐츠를 생산하기 위해서는 기술을 쉽게 사용할 수 있도록 제작자의 편리성을 고려한 기술 서비스의 제공이 필요하다. 본 논문에서는 실감 콘텐츠 제작 편리성을 위한 개인방송용 NUI 기술 서비스에 대해 논하고자 한다. 콘텐츠의 다양성과 빠르게 변화하는 IoT 기기 확장성을 고려하여 이와 연동 가능한 제스처 인식, 음성 인식 등과 같은 비 접촉식 NUI 서비스 기술과 이를 활용해 방송 제공자가 편리하게 다양한 콘텐츠를 제공할 수 있는 서비스 개념도를 제안하고, 관련 API 설계에 대해 보인다. 본 연구를 통해 개인방송을 접하는 사람들의 편의성, 흥미를 만족시켜 다채로운 서비스를 제공할 수 있고 나아가 편리성을 고려한 NUI 서비스 가이드라인을 마련할 수 있을 것으로 기대된다.

본 논문은 패밀리 레스토랑의 웹 사이트를 방문하는 사람들이 웹 사이트에서 느끼는 '즐거움, 정보활용성, 거래편리성, 잠재적 이익, 상호작용'에 구전효과가 어떤 영향을 미치는지, 그리고 '고객태도'와 '추천'에는 어떤 영향을 미치는지 파악하였다. 연구결과는 다음과 같다, 첫째, 즐거움, 정보활용성, 잠재적이익, 상호작용은 태도에 직접적인 영향을 미치고, 태도는 추천에 직접적인 영향을 미치는 것을 확인하였다. 그리고, 즐거움, 정보활용성, 잠재적 이익, 상호작용은 추천에 간접적인 영향을 미쳤다. 둘째, 거래 편리성은 태도와 추천에 유의한 영향을 주지 못했다. 거래 편리성은 직접 패밀리 레스토랑을 이용한 후에 느끼는 부분의 성격이 크다. 웹 사이트에서 제공하는 할인쿠폰이나, 다양한 이벤트 활용이 쉬운지를 판단하는 항목인 거래 편리성은 편리함이 태도 형성과 추천에 큰 요인은 아님을 보여준다. 마지막으로, 태도가 추천에 영향을 줄 때, 구전효과의 영향은 크지 않음을 보았다. 태도는 고객이 직접 웹 사이트를 충분히 활용하면서 패밀리 레스토랑의 서비스를 실제로 경험하며 직접 느끼는 것을 포함하기 때문에, 구전효과의 영향은 적은 것으로 보인다.

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.

E-authentication is one of the key functions for electronic transactions with the identification function made through the information systems. With the abolition of the mandatory use of public certificates, various private e-authentication services have emerged, and are developing to provide various additional services in addition to e-authentication. In this study, we explored the factors that affect user satisfaction with e-authentication services, compared the relative influence among the factors that we explored, and produced implications that could contribute to strengthening the competitiveness of e-authentication services. Based on the characteristics of e-authentication service, we searched and found four factors such as availability, convenience, added functionality and security. After that, we established and analyzed our research model to analyze the causal relationship between these four factors and user satisfaction. The analysis results showed that availability, convenience and security had significant effects on user satisfaction, but added functionality had no significant impact. In addition, compared to availability and convenience, security had a very strong impact on user satisfaction. This study suggests that e-authentication service providers should make efforts to make users aware of the usefulness of additional services while enhancing security.

A coastal ferries, which serve as a mode between mainland and offshore islands, are frequently used by islanders and travelers visiting islands. Therefore, it is located in a place with good accessibility to the downtown so that users can use it conveniently. However, research on the built environment and walking environment of coastal ferry terminals has not been conducted to ensure that elderly islanders and general travelers can use comfortably the coastal ferry terminal. In this study, with a focus on the coastal ferry terminal space, the walking section was set as 1)the accessibility of the coastal ferry terminal, 2)the built environment for using the coastal ferry terminal, and 3)walking environment in the ferry boarding and disembarkation at the coastal ferry terminal, and 4, 5)walking environment in the ferry. An evaluation tool was developed to measure the walking environment for each walking section, and the importance and satisfaction of users were analyzed using the IPA for the Yeosu Coastal Ferry Terminal. As a result, in the process of approaching the ferry terminal, 'convenience of using public transportation by foot' and 'convenience of using signposts guiding the location and direction of the ferry terminal' were investigated as concentrated areas. On the other hand, the built environment inside the ferry terminal and the walking environment showed that the satisfaction of the users was high. Regarding the walking environment from the ferry terminal to the ferry, the 'surface walking environment of the walking path', 'convenience of walking with luggage', 'convenience of walking in the slope section', and 'convenience of walking in the ferry ramp section' showed low satisfaction. This study can be used as basic data for improving the facilities and walking environment of Yeosu Coastal Ferry Terminal and is expected to be used as data for comparative research with other coastal ferry terminals.

This study is an empirical analysis regarding what kind of factors affect the intention to use autonomous vehicles. For the empirical analysis the research model was derived from value-based adoption model base and integrated some aspects that only autonomous vehicles have. At default variables of VAM are usefulness, enjoyment, technicality, perceived cost, some autonomous vehicle related variables were added, and those are convenience, safety, security, social influence. A survey was done in order to empirically analyze with this research model, and 216 valid survey answers were chosen to analyze. Empirical analysis was done by structural equation using AMOS24. The result of empirical analysis were as follows. Variables usefulness, enjoyment, safety, security had a significant positive effect on perceived value. Technicality and perceived cost had a significant negative effect of perceived value. In addition, security and social influence had no significant effect on perceived value. Furthermore, perceived value had significant positive effect on intention to use. Among the variables that came out to be significantly positive, the most influencing variable was safety, followed by convenience, perceived cost, enjoyment, usefulness and then technicality. In addition, the analysis of mediating effect of perceived value shows that usefulness, enjoyment, convenience, safety, technicality, perceived cost had mediating role towards intention to use. However, security and social influence had no siginificant mediating effect towards intention to use. Considering all these research results this study has provided theoretical and practical implications to researchers on the intention to use autonomous vehicles.
