Smart devices have a variety of affordances to foster meaningful learning in elementary school. For the design of smart learning environments, more research is needed to understand students' smart device usage and their perception of learning with smart devices. In order to capture smart device usage profiles among elementary school students in South Korea, this study carried out Latent Profile Analysis with three constructs: information search, communication, and study. Participants (n=253), who ranged from the fourth to the sixth grade students, were classified into three profiles of smart device usage: low-activity, communication, and high-activity groups. The smart device usage profiles varied depending on smartphone usage experience, and the profiles were significantly related with smart device addiction, not with smart device usage ability. Perceptions of smart education were also significantly associated with the profiles. The high-activity group showed more positive attitudes toward smart education than the others, but no significant difference was found in regard to negative attitudes. Based on the findings, this study discussed implications for the use of smart devices in elementary school.

A novel concept of ICT based service, which is called N-device service, is proposed and implemented in the form of N-device smart education services. The N-device services are different from the existing N-screen services in terms of the number of devices a user is using for a specific service at the same time. A N-device service consists of several smart devices which are different in size, software and hardware platform, mobility, manufacturer and the like by fully utilizing the characteristic of each device. The major and unique features of N-device services are analyzed and depicted in a strict way. Those are shared role for each device, service by configurable device, one sensor multiple use, real-time data sharing, role shifting and new market creation. It is turned out that the N-device service is more human centric compared with existing ICT based services and can give richer digital experience to users because non-existent services become possible with the new concept. However, there exist several barriers to be implemented and commercialized in the real world. Those include high development cost and time, small market and different application platforms of devices. These barriers can be overcome by technical advances and cooperation between relevant parties. The smart education is very prominent area, in which the novel concept can be applied with high priority because Korean government announced its plan to boost up new educational services with big budget and these are acceptable by enthusiastic Korean parents and students. That's why the N-device service is implemented in the education area, which is called as "livessam(live teacher)," with four smart devices, IPTV, tablet PC, PC and smart phone. By providing both detailed service scenario and techniques, we shows that the novel education service is technically feasible and acceptable by teachers and students.

The purpose of this study was to examine the pathways between mothers' inappropriate smart device usage habits, preschoolers' immersion tendency and self-regulation, and children's cognitive ability. The subjects of the study were 308 preschoolers aged 4 and 5 years and their mothers in Seoul, Gyeonggi-do, Incheon, Gangwon-do, Daejeon, Busan, and Mokpo. Data were analyzed with descriptive statistics, t-test, one-way ANOVA, and Pearson correlation using the SPSS 25 program. A sequential mediation model was analyzed using the AMOS 22 program. Mothers' inappropriate smart device usage habits were found to have a negative effect on the preschoolers' self-regulation, and this association was mediated by the preschoolers' smart device immersion tendency. These findings show the mechanisms through which mothers' inappropriate smart device usage habits negatively affect preschoolers' smart device immersion and self-regulation which, in turn, has a negative impact on cognitive ability

In this paper, we use scratch to design and develop non-formal learning experiences that are linked with contents of secondary science textbook to educational programs. The goal of this paper is to develop a convenient and interesting program for non-formal learning in a learning environment using various smart device. Theoretical approaches to mobile education, such as smartphones, and smart education support policies continue to lead to various research efforts. Although most of the smart education systems developed for students who have difficulty in academic performance are utilized, they are limited to general students. To solve the problem, the learning environment was implanted by combining the scratch, which is an educational programming that can be easily written. The science education program proposed in this paper shows the result of process of programming using ICT device using scratch programming. In the evaluation stage, we were able to display the creations and evaluate each other, so that we could refine them more by sharing the completed ideas.

본 논문에서는 스마트 디바이스의 MAC address를 이용한 bluetooth 기반의 건물 출입통제 시스템을 제안한다. 제안하는 출입통제 시스템은 서버에 등록된 MAC address와 출입자의 스마트 디바이스 MAC address를 비교하여 일치 여부에 따라 출입통제가 이루어진다. 실험 결과, 스마트 디바이스와 bluetooth 모듈의 bluetooth 페어링만으로 출입문의 통제가 가능하기 때문에 별도의 출입 도구가 필요하지 않고, 출입 승인을 위한 행동이 생략됨에 따라 기존 출입통제 시스템에 비해 출입 승인절차가 간소화되어 편의성을 향상시킬 수 있다.

이 논문의 연구가설은 스마트기기 활용 교육이 장애인들의 교육 및 학습효과로 스마트기기에 대한 사용능력과 활용 정도의 수준을 높여줄 수 있을 것이라는 것이다. 한국정보화진흥원의 '2012년 정보격차 실태조사 원자료' 중 장애인 데이터를 사용하고, 표본선택편의문제 해결을 위해 Heckman의 2단계 추정법을 활용하였다. 실증 분석결과, 스마트기기 활용 교육을 받은 장애인일 경우 종합적인 스마트기기 사용능력과 활용도 수준이 각각 더 높다는 가설이 채택되었다. 스마트기기 사용능력 및 활용도 측면에서는 스마트기기 활용 교육과 높은 학력 가구소득, 전문사무직, 젊은 연령층 등이 긍정적인 유의미한 영향을 미쳤고, 특히 지체장애에 비해서 시각장애일 경우 스마트기기 사용능력 및 활용도 수준이 낮아지는 것으로 나타났다. 이는 시각장애의 경우 특수 보조기기 및 어플리케이션 없이는 생활이 거의 불가능하므로 지체장애의 경우 두 팔 또는 두 손 전체에 이상이 있는 중증장애가 아닌 한 스마트기기 활용 교육을 통해 스마트기기 사용능력 및 활용도 수준이 높아짐을 알 수 있었다. 본 연구결과는 장애인의 스마트기기 활용도를 높이기 위한 공공 정책 또는 민간 협력의 교육프로그램 진행이 그 목적을 달성하면서 교육의 긍정적인 효과를 보여주면서, 한편 장애유형에 따라 보다 정교한 교육내용과 방법이 필요하다는 것을 보여준다.

스마트 시대와 더불어 스마트 교육이 시행되었지만, 활성화되지 못하고 현재는 잠정적으로 중단된 상태이다. 스마트 교육에 필수인 디지털 콘텐츠가 부족하고 질이 낮으며, 교육 기자재도 가격이 비싸고 도입 예산에 비해 효과가 적기 때문이다. 본 논문에서는 학생들의 학습을 효과적으로 지원하기 위한 스마트 교육에 필수적인 디지털교과서와 교육 기자재의 도입에 중점적으로 고려해야할 호환성과 사용성을 분석한다. 본 논문을 통해 제한된 예산을 사용하는데 최적의 교육 효과를 나타낼 수 있도록 하여 침체된 스마트 교육 확산을 다시 활성화하고, 스마트 교육의 종주국으로서 위상을 제고하며, 교육의 질을 높여 국가의 미래 발전에 기여하고자 한다.

The purpose of this study was to investigate the association between dietary quality and smart device use among middle school students. A total of 330 middle school students (171 boys and 159 girls) residing in Incheon participated in this questionnaire survey in June 2018. The boys and girls were divided into two groups according to their daily use time of smart devices: less than 3 hours a day (<3 hours) and 3 hours or more a day (≥3 hours). Eating habits and dietary quality were assessed using a nutrition quotient for adolescents (NA-Q). For boys and girls, higher consumption frequency of white milk was significantly associated with less time spent using a smart device. For boys, a higher number of vegetable dishes and eating frequency of breakfast were significantly associated with the less time spent using a smart device. For girls, higher consumption frequency of processed beverages, ramyeon, and street foods was significantly associated with more time spent using a smart device. For boys and girls, those who spent more time using a smart device had significantly lower NA-Q scores, indicating low dietary quality. To sum up, more time spent using a smart device among middle school students may be associated with lower dietary quality. These results suggest the need to provide a nutrition education program and guidelines to students who use smart devices for a long time.
