The purpose of this paper are to analyze about sleeping and eating habits of children and to propose short and long-term plans for problems. To analyze problems of sleeping and eating habits of children, we did survey for children. The oriented children of survey are students who are the third grade or sixth grade of elementary school. They are distinguished between rual and urpan area. The main of survey are the purpose of using computer, computer using time, daily sleeping time, the quality of sleeping, the cause of insufficient sleep and change of eating habits by using computer. According to result of survey, computer using time affect sleeping and eating habits in case of a part of children. Therefore, a teaching plan for computer using habits is needed in elementary school.

This study was intended to investigate whether the computer use hours affect physical development, dietary habits, and nutritional status or not. One hundred and ninety elementary school students from Gyeonggi province and Seoul were selected and surveyed during December, 2006. Participants were divided into 2 groups: long-time computer user (${\geq}$ 2 hrs./day) and short-time computer user (<2hrs./day). The survey included the questionnaires and anthropometric measurement. A dietary survey was conducted by using 24-hour recall method. The most of long-time computer user accessed computer more often than those of short-time computer user weekly bases. The purpose of the computer use was for the computer game (p < 0.05). Most participants accessed computer after the school at night and at their home. The longer the computer use, the more the body weight and %RBW (p < 0.05). Dietary habits score of long-time computer user 34.5 points) was lower than that of short-time computer user (38.0 points) (p < 0.001). The long-time computer user consumed more fatty foods, instant foods, and sugary foods. In case of dietary habit changes incurred by computer use, the long-time computer user had inferior dietary habits: skipping meals, meal size, appetite, eating speed, weight, exercise, and sleeping trouble (p < 0.05). The long-time computer user consumed less calories than the short-time computer user (p < 0.05). Also, the long-time computer user tended to have lower intakes of vitamin C, Ca, and dietary fiber without significance. From the findings, the longer use of computer by the elementary school children negatively affects their physical development, dietary habits and nutritional status.

The main objective of this study was determine why employees conduct non-work related smartphone use at work. To do this, this study developed the research model of non-work related smartphone use behavior consisting of factors such as habit, intention, social effect, task interdependence, and behavior. And it was tested via a survey of employees using smartphones. The results of this study reveal, first, that habit and social influence are significant predictors of non-work related smartphone use behavior. Secondly, task interdependence has a positive moderating effect between intention and behavior in non-work related smartphone use.

The main objective of this paper is to investigate why university students use their smart phones in class and to develop a predictive model of smart phone use behavior that consisted of perceived benefit, perceived cost, attitude, social effect, intention, and habit. The proposed model is tested using survey data collected from 120 university student smart phone users. PLS analysis show as following: At first, intention and habit are significant predictors of smart phone use behavior in class. Secondly, perceived benefit and perceived cost as well as attitude and social effect are the factors affecting smart phone usage in class.

모바일 간편 결제란 모바일을 통해 재화, 서비스 이용에 관련된 결제를 처리하는 것을 의미한다. 모바일 접속자가 늘어나고 모바일 채널로 구매하는 사용자 규모가 커짐에 따라 모바일 간편 결제 시장은 지속적으로 성장되고 있다. 따라서 본 연구에서는 청소년을 대상으로 모바일 간편 결제에 대한 이용 실태를 조사하고자 한다. 정보기술에 대한 개인혁신성과 현금 결제 습관을 사용자의 개인적 속성으로, 사용자가 인지하고 있는 위험성과 상대적 이점을 지각된 신념으로 보고 모바일 간편 결제 이용에 대한 청소년들의 인식을 연구하고자 한다. 대부분의 학생들이 온라인/모바일 쇼핑을 통해 모바일 간편 결제를 많이 사용하는 것으로 나타났으며, 상대적 이점이 있다고 높게 생각하고 있고, 현금 사용에 대한 습관 역시 높게 나타났다.

In this paper, I analyzed the cause on difference of ICT literacy level according to region scale in elementary school. According to precedent research, ICT literacy score of elementary student in 2016 were higher in order of big city, small city and rural area. To find the cause of difference by region scale, I compared ICT literacy score and ICT use habit. As a result, The cause for this is that students in large areas have more chances to use computers at home, learn more with computers, and have more information (computer) education than students in small areas appear. Therefore, Based on the results of this study, I proposed methods to reduce the regional ICT literacy score difference. The methods are to provide computers for low-income students, to guide learning methods using computers at home, and to provide more computer education opportunities.

최근 삶의 질이 향상된 것과는 다르게 만성질환을 겪게 되는 사람의 수는 점점 증가하고 있으며 만성질환은 꾸준히 관리해야 하는 질병이지만 일반 사람들이 스스로 모든 것을 관리하면서 꾸준하게 동기를 부여하기에는 쉽지 않다. 본 논문은, 이에 관해 관심을 가지며 사람들이 항상 사용하는 핸드폰에서 쉽게 개선을 할 수 있는 식습관을 계획하고 실천할 수 있는 동기를 부여하며 최종적으로 사람들의 식습관을 개선함과 동시에 건강개선도 할 수 있는 애플리케이션을 제작했다.

This paper aims to design and implement a robot that will help teach children living habits and English conversation education in dual-income families using the open platform robot Q.bo one based on raspberry pi3 of a single board computer. The first function of life habit formation is to help children to wash their hands, to brush their teeth, homework and sleep regularly. The child is then photographed listening to the notification and acting so that the parent can identify and provide feedback. The second basic conversation education feature uses Google's DialogFlow to help children learn English naturally through simple English conversation through the robot. The two-functioning robot allows children from working families to feel secure by printing their parents' voices even when they are not at home. At the same time, it allows them to get into basic lifestyle, to have basic English conversation with robots, and to be interested in English early.
