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.

Since smartphone market got matured, market size and penetration rate are decreased. But smartphone is still one of most important daily commodities today. These days, most important issue about smartphone is the government regulation of subsidies. Therefore how smartphone subsidies marketing and government regulation affect purchasing intention and furthermore advise on government policy is the purpose of this research. In terms of characteristic of smartphone, this research analysed functional characteristic, service characteristic, and economical characteristic studied previously. And also studied about how government regulation affects purchasing intention on the group agrees regulation. As a result, functionality, price and converting cost has significant relationship with purchase intention, but government regulation on subsidies doesn't.

We development the service that teacher and parent can control the smart phone of student in school and home, the name is I_smart_keeper. The service is composed of server system, teacher's application, parent's application and student's application. The control of student's phone in school is operated by school timetable and GPS(Global Positioning System) in smart phone. The student's phone is operating one of six policy. The six policy is 'emergency call only', 'specific application only', 'call only', 'call and text only', 'all allowed' and 'all lock'. The teacher can change the current policy with his or her phone, That is a the temporary policy can be applied on a day. In school hours, teacher is able to instruct student using application appropriate to the teaching. If student is leaving school early and located outside school, the service do free the student's phone by GPS of her or his phone. We show the Smart Health Indicator (SHI)that analyse the pattern of student's phone habit and SHI will guide a desirable student's phone habit. In home, parent can control child's phone. The service will help the risk reduction of a robbery case due to keeping student's phone by teacher in class. Currently one elementary school's all student use I_smart_keeper and three elementary school is testing to some class. The teacher's impression was very good and they usually use I_smart_keeper for class in positive light. Survey results for students with higher satisfaction.

우리나라는 후발주자임에도 불구하고 개방형 운영체제의 전격적 채택과 고급 기종 중심의 공격적 제품 라인 확대, 그리고 가치사슬의 수직 통합 체계 구축 등에 힘입어 2011년 세계 스마트폰 시장 점유율 1위를 차지하였다. 그러나 우리나라 스마트폰 산업은 시장 점유율 1위를 달성한지 4년만인 2015년 또 다른 후발주자인 중국에 추격을 허용하였다. 이와 같은 스마트폰 산업 주도권 이전 현상을 논의하기 위해 본 연구는 추격 사이클 이론에 기반하여 중국 스마트폰 산업의 추격과 관련한 기술 수요적 정책 및 제도적 기회의 창을 고찰하고, 이에 대한 중국의 전략적 대응과 우리나라의 실책을 논의하였다. 먼저 기술적 기회의 창으로 스마트폰 아키텍처의 모듈화와 시스템 반도체의 원칩화는 스마트폰 생산에 필요한 기술적 지식의 장벽을 낮추는데 기여하였다. 또한 2013년부터 급성장하기 시작한 저가(190달러 이하) 스마트폰 시장은 기술적 열위인 중국의 시장 개척에 우호적 기회로 작용하였다. 이와 함께 중국 정부의 스마트폰 관련 연구개발 투자 확대는 중국에게 우호적 사업 환경을 제공하는 정책적 기회의 창으로 작용하였다. 이와 같은 기회의 창을 활용하기 위해 중국 스마트폰 산업은 빠른 시장 진입, 원가 절감을 위한 현지 부품 채용, 정부 연구개발 투자를 활용한 기술 역량 축적 등의 전략적 대응을 전개하였다. 반면 우리나라는 고급 기종 생산 고수와 저가 기종 출시 지연, 수직통합 체계의 고착화에 따른 부품 경쟁력 악화에 따라 중국에 추격을 허용하게 되었다. 본 연구는 산업 주도권 이전 현상에 대한 최신 실증을 추가함으로써 추격 사이클 이론의 발전에 기여할 것으로 기대되며, 향후 우리나라 스마트폰 산업 발전 정책 발굴에 중요한 지침으로 활용될 것으로 기대된다.

The smart phone industry has shown its continuous growth even under global economy crisis and its ecological surrounding is rapidly shifting. In order to retain its global competitive advantage, it is necessary to comprehend and implement a preemptive policy regarding ecological transition of smart phones. Many developed foreign countries including the United States and Europe endeavor to maintain competitiveness in the new ecology of smart phones. Korea, which was once the most leading country in the IT industry, has accepted the fact that it lost an opportunity to take competitive advantage in the market and now it is striving to regain its past reputation. This study aims to examine the new potential category of services and products in this rapidly changing smart phone market and also suggested necessary additional efforts from the government side. We expect this study help the government establish proper ecological policies under Korea's smart phone environment.

우리는 지금 스마트 사회에 살아가고 있다. 언제 어디서든 스마트 디바이스를 통해 기존에 PC에서 하던 작업들을 손쉽게 하고 있다. 한편 스마트폰의 확산으로 이용자 수가 급증하고 있는 소셜네트워크 서비스(SNS)는 이용자들이 자신의 일상적인 이야기를 사이버공간에 게시함으로 인해 개인의 사생활 정보들이 노출되고, 그러한 정보들이 범죄에 악용되는 사례들이 눈에 띄게 증가하고 있다. 또한 SNS를 이용한 악성코드의 유포 및 빠른 전파 등도 새로운 보안위협으로 나타나고 있다. 그 밖에 스마트 기기를 대상으로 한 해킹 및 악성코드 감염 등 위협이 증가하고 있는 형편이다. 본고에서는 스마트 사회의 주요 보안위협을 살펴보고 미국, 유럽, 일본, 호주 등 선진국의 관련 정책 동향과 국내 정책과 실태를 분석하여 새로운 정보보호 정책 수립 방향을 제언하고자 한다. 스마트 사회 위험 요소로 가장 보편적으로 사용되고 있는 스마트폰과 스마트폰을 통해 이용되고 있는 소셜네트워크 서비스, 클라우드 서비스의 보안위협을 제기하고 최근 글로벌 이슈로 떠오르고 있는 빅 데이터 환경의 보안위협을 분석하였다. 스마트 사회의 위협을 대비하고 있는 주요국 정책을 살펴보면, 미국의 경우 사회적 합의를 바탕으로한 감시와 통제를 강화하는 정책을 추진 중에 있으며 유럽의 5개국 EU5(영국, 독일, 프랑스, 스페인, 이탈리아)는 스마트폰 위협을 중심으로 공동 대응 방안을 마련하고 있다. 일본은 스마트 워크중심의 보안대책을 강구하고 있으며 호주는 스마트 사회 보안위협에 대한 국민의 인식제고에 주력하고 있다. 국내의 경우도 스마트 사회의 보안위협에 선제적 대응을 위하여 "스마트 모바일 시큐리티 종합계획"을 수립하여 추진중에 있다. 하지만 보안 실태를 보면 스마트 사회 보안위협에 대한 이용자들의 우려는 높은 반면 기업의 보안 대책 마련에 대한 투자는 여전히 미흡한 상황이다. 향후 우리 사회가 디바이스간 융합을 넘어 모든 사물이 연결되는 초(超)연결(Hyper-Connectivity) 시대로 진화되어 가면 편리성이 증대되는 만큼 더 많은 위협에 우리의 일상이 노출되는 문제가 발생하게 될 것이다. 안전한 미래 사회로 진입하기 위해서는 보다 체계적이고 종합적인 정보보호 정책마련이 필요하다. 본고에서는 이를 위한 정책수립의 방향을 제언했다.

In the information age, the rapid development of information technology provides people with an enriching experience yet also causes them harm because of information security (IS) issues. The IS of smartphones faces great challenges. Although many studies on IS awareness have been conducted, most of them have focused on PCs and do not consider the security issues of smartphones. In this study, we focus on those factors that affect IS awareness for both PCs and smartphones. We also analyze the differences in the impacts of certain factors on PCs and smartphones based on the proposed research model. The results are summarized as follows. First, the understanding of security technique, understanding of IS threat, and IS education have significant impacts on IS awareness for PCs and smartphones, while IS intention has a significant impact on IS awareness for PCs but not for smartphones. Moreover, IS policy has no significant impact on IS awareness. Second, PCs and smartphones show no significant differences in IS awareness, IS threat, and IS intention, but show significant differences in understanding of security technique, IS education, and IS policy.
