Reliable functionalities for autonomous navigation and object recognition/handling are key technologies to service robots for executing useful services in human environments. A considerable amount of research has been conducted to make the service robot perform these operations with its own sensors, actuators and a knowledge database. With all heavy sensors, actuators and a database, the robot could have performed the given tasks in a limited environment or showed the limited capabilities in a natural environment. With the new paradigms on robot technologies, we attempted to apply smart environments technologies-such as RFID, sensor network and wireless network- to robot functionalities for executing reliable services. In this paper, we introduce concepts of proposed smart environments based robot navigation and object recognition/handling method and present results on robot services. Even though our methods are different from existing robot technologies, successful implementation result on real applications shows the effectiveness of our approaches.

This study aims to identify the factors that influence adoption intentions towards portable Internet service, based on the individual characteristics that assist in creating markets and developing strategies. Two types of factors are defined: individual characteristics including demographics, existing services usages, prior knowledge, adoption attitudes, and service evaluations; and adoption intentions including the willingness to subscribe, subscription term, willingness to pay, usage type, and preferred terminal. The results indicate that the importance of demographic variables depends on adoption intentions, and that users of mobile Internet service and wireless LAN are probably targets for portable Internet service. Furthermore, the results demonstrate the need for an enhanced perception of the usefulness and ease of use of service, as well as an intensive marketing activity for potential users and a bearable innovation to stimulate the market for portable Internet service.

Internet of things (IoT) is based on a global dynamic information network with cloud services where a great number of devices (things) exchange data to provide added-value services and products. There are several commercial and open source IoT platforms available in the market to connect devices to internet; however, they have cost and operational constraints that make them not suitable for academic projects. In this work, an IoT platform, known as Novus-io, is introduced in order to support academic projects for undergraduate students. With this platform and proper training, undergraduate students from different majors (not only from information technology and electronics) are capable to upgrade their school projects with IoT functionalities. The objective of this approach is to provide to any undergraduate student skills and knowledge on IoT, so they will be prepared, in their imminent step toward professionalism, to understand the relevance of digital services in today's world.

최근 ISO/TC211, OGC, INSPIRE 등 국제기구들을 중심으로 시맨틱 기술을 활용한 공간정보의 공유 노력이 진행되고 있다. 또한 스마트폰의 대중화와 소셜 네트워킹 서비스의 활성화로 인해 온라인 소셜 커뮤니티에서 이슈를 추출하기 위한 연구들이 이루어지고 있다. 그러나 응용 수준에서 가용한 공간정보 온톨로지는 부족한 실정이며, 소셜 네트워크 서비스에서의 공간정보 추출 역시 텍스트 마이닝을 통한 지오코딩 부분에 집중되어 있다. 따라서 소셜 미디어 정보에서 공간 현상을 추출하여 시맨틱 공간 지식으로 변환하기 위한 방법은 매우 유용하게 활용될 수 있다. 또한 공간 현상을 단순한 빈발 키워드가 아닌 연관 이슈의 형태로 사용자에게 제공함으로써 공간상에 발생하는 이슈에 대한 이해도를 향상 시킬 수 있을 것이다. 따라서 본 논문에서는 소셜 미디어 서비스의 하나인 마이크로 블로그를 기반으로 데이터를 수집하여 데이터 마이닝 기술을 접목하여 연관 이슈를 추출하고, 이를 시공간 지식으로 변환하기 위한 공간 이슈 온톨로지 모델을 제안하였다. 이를 통해 향후 관련 시스템의 개발을 위한 참조모델 및 공간 온톨로지 구축을 위한 모델로써 유용하게 사용될 수 있을 것으로 기대된다.

FTA(Free Trade Agreement) 환경에서 수출입 기업이 무관세 혜택을 받기위해서는 원산지 규정을 준수하는 일이고, 이를 위해 가장 먼저 선행되어야하는 것이 물품의 품목분류가 필요하다. 이를 위해서는 관세율표를 구성하고 있는 HS(Harmonized System) 품목분류의 기본원리에 대한 철저한 이해가 전제되어야하며, 품목에 대한 호(Heading)에서의 상품명에 대한 이해와 관련 영역(section)이나 해당 영역(chapter)의 주(Note)는 물론 해설서의 규정까지 이해하고 있어야 올바른 품목분류를 할 수 있다. 이러한 문제점을 해결하기 위해 본 논문은 물품의 특성을 잘 알고 있는 경우, 업무 담당자도 쉽고 정확하게 분류할 수 있도록 품목분류의 결정에 영향을 줄 수 있는 7가지 결정요소를 시스템에서 먼저 제시하여 사용자가 선택하도록 하고, 각 산업에서 통상적으로 통용되는 현장용어 지식을 포함하는 융합적 수행시스템 기반의 HS 품목분류 서비스 개발을 제안하였다. 마지막으로 이 시스템의 실제 기업 현장 적용을 통해 효과를 검토하였다.

The rapid changes in business environments are also applicable to the delivery service field. Numerous companies are using smart phones in order to perform work of the delivery service field that is rapidly developing every year. Smart phones established ubiquitous work environments where access to the server of the head office is possible through telephones, scanners, and the internet anywhere and anytime. However, although smart appliances including smart phones have been diffused, empirical analysis of use of them in actual has not been attempted much. In this regard, current study empirically analyzes how connectivity and context-awareness function of smart phones based on the TAM(Technology Acceptance Model) influence the continuous intention to use through trust, usefulness, and ease of use. The results indicate that the connectivity and context-awareness function, which are natures of smart phones, had impacts on the ease of use and trust, but not on the usefulness. Based on these results, this study suggests implications and future research directions regarding the planning and realization of smart appliances.
