The high rates of smartphone usage among younger people and the negative impacts are well-known, but there remains a paucity of qualitative research on the topic. This study was designed to explore the experiences of university students addicted to smartphones. The author conducted in-depth individual interviews with 17 university students who scored in the upper 5th percentile on a smartphone addiction scale. All interviews were audiotaped, transcribed, and analyzed using qualitative content analysis. Students with a smartphone addiction were trapped in a vicious cycle. More specifically, they were "Realizing something was wrong with withdrawal symptoms," "Having negative consequences," "Seeking escape," and "Staying addicted." This study helped participating students realize their addiction and disclose their emotional and interpersonal difficulties related to their smartphone use. These understandings may be used to refine and further develop school-based programs to better help those addicted to smartphones to recover.

This study was conducted to investigate the pre-service teacher's perception of the possibility of using smartphones in the classroom, moreover, to confirm the policy related to using smartphones in schools. For the objectives, this study, firstly, investigated the pre-service teacher's awareness of having cellphones in the classroom, secondly, analyzed the pre-service teacher's opinion of using smartphones for educational objectives and elements for those investigated objectives, finally, investigated the school policy for educational objectives of using smartphones. The participants of this study were 146 pre-service teachers among three universities in Seoul. The results showed that the pre-service teachers opposed using cellphones in the classroom. Next, it was found that most of them had smartphones and they knew how to use them effectively. For the aspects of educational use of smartphones, they recognized that smartphones could be used as a smart educational tool, an efficient teaching and learning tool, and an assistant tool for teaching and learning. In order to use smartphones for the investigated educational tools, the learning contents, the ways of teaching and learning, and the technical support of the school should be prepared. Finally, the pre-service teachers thought that the school policy should be changed in order to use smartphones for educational objectives, and the school policy with regard to using smartphones in the classroom should be decided by the teachers. Most of all, for the educational use of smartphones, the pre-service teachers believed that the change of the students' perception was the most significant.

세계적으로 스마트폰 성장의 축이 중저가로 이동하고 IoT에 대응하는 성장 모멘텀을 찾는 추세이다. 최근 구글의 조립식 스마트폰 프로젝트(Ara)의 진행은 전략적 기술지향점과 지속적인 시장지배전략을 수렴해가려는 산물로 분석된다. 구글안경(2013), 스마트워치(2014), 조립식스마트폰(2015) 등의 상용화출시나 출시예정에 대한 발표는 기존 시장에서 전개되어온 구글의 OS플랫폼 지배전략(70~80%)을 하드웨어 플랫폼을 통해서도 전개할 것임을 강력히 시사하고 있다. 한국은 스마트폰 이후를 준비하면서 조립식 스마트폰과 워치의 파괴적 영향에 대비하여, 심층적인 기술개발 및 시장 대응전략의 수립과 IT융합 산업의 동력원으로 연계하기 위한 연구가 시급한 시점이다.

최근에 ICT 융복합 인프라가 많은 관심을 받으면서 사용자 측면에서의 정보호호를 위한 기술 요구와 함께 이에 대한 표준화가 추진되고 있다. ICT 융복합 인프라 분야 중에, 스마트그리드 보안은 전력 정보 등이 안전하게 전달되어 사용자에게 더욱 편리한 서비스를 제공할 수 있도록 표준화를 추진하는 분야이다. 반면 스마트폰 보안은 스마트폰 애플리케이션 보안 표준화를 통해 사용자가 스마트폰을 안심하고 사용할 수 있는 환경을 조성해줄 수 있다. 본 논문에서는 ITU-T SG17에서 국제 표준화로 추진되고 있는 다양한 연구 분야 중에, 스마트그리드 보안과 스마트폰 보안에 대한 추진 동향을 기술하도록 한다.

Smart car is a vehicle which maximizes convenience, safety, and user experience. The traditional vehicle style will be replaced by a smart car. The objective of this paper is to find essential quality attributes that consumers want. We provide a method to select a best smart car reflecting their preference based on the quality attributes. We derive Kano's quality attributes by an exploratory survey and show an example to implement their decision using the Analytic Hierarchy Process method. As a result, the quality attributes were classified into two groups of attractive quality and indifference quality. The respondents evaluated that the safety of smart cars was more important than the convenience and user experience. However, the smart car was required more functions related to the convenience criteria. These results will provide important implications for smart car design.

Smart work is a new paradigm of the way of working for knowledge workers. We propose a model which determines the levels of smart work. As the determinants, we identify freedom from both space and time. As an extension of the model by adding a new determinant of the mobilization of social intelligence, we show that a new smart work model, smart work 2.0, can be derived. For successful implementation of smart work 2.0, we also provide strategic suggestions, along with the implication of the study and future research direction.

스마트 폰의 등장으로 인해 사용자들은 모바일 기기를 통해 언제 어디서나 인터넷 서비스를 이용할 수 있게 되었고 더불어 다양한 앱을 통해 기존에 PC에서 제공되던 서비스들이 모바일 기기로 이동하게 되었다. 이러한 변화는 TV시장에도 영향을 미치게 되었고 TV에서도 인터넷 서비스뿐만 아니라 다양한 앱 서비스를 이용할 수 있는 스마트TV 시대를 열게 되었다. 스마트 TV시스템은 방송망과 인터넷 망을 통해 사용자에게 보다 다양한 멀티미디어 콘텐츠 서비스를 제공할 수 있게 되었으나 각 인터넷 콘텐츠 제공자가 앱 형태로 콘텐츠를 제공함으로써 다양한 콘텐츠 제공자로부터 사용자가 원하는 멀티미디어 콘텐츠를 검색하는 데에 한계가 있었다. 본 논문은 사용자 키워드 검색문 의미해석을 통해 서로 상이한 멀티미디어 콘텐츠 메타데이터 정보 구조를 가지고 있는 콘텐츠 제공자들이 효과적으로 검색결과를 제공할 수 있는 스마트TV통합검색시스템에 대하여 기술한다.
