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.

The purpose of this study was to investigate the perceptions, intake levels and information needs of elementary school students on artificial food colorants in order to provide better understanding and proper dietary education to these students. From May to June 2010, a survey was conducted from 315 elementary school students at fifth and sixth grade level who were living in Seoul. The questionnaire was distributed by 14 elementary school teachers to their classroom students. The results showed that food safety was regarded as the most important factor in purchasing food items, and artificial food colorants were the most interested among various food additives. Although there was a lack of general knowledge and the students' estimated intake levels of artificial food colorants from processed foods were comparatively low, most (82.7%) believed that artificial food colorants were dangerous for health. The information they wanted to know most was the safety, necessity, and function of artificial food colorants, in order. Above results suggested the necessity of providing accurate information on artificial food colorants to elementary school students possibly by developing educational materials which can improve the perceptions on artificial food colorants and encourage a safe dietary life.

The purpose of this study is to consider the home environment and awareness of elementary school students in the first grade of elementary school, and to find ways to support them. Participants were 31 1st graders in elementary schools nationwide. Data collection was conducted from June 6, 2017 to July 7, 2017. The focus group interview was used as a data collection method for this study. Results were analyzed as 'The Changing family environment that first graders think' and 'First graders' awareness of elementary school'. 'The Changing family environment that first graders think' include 'Changes in language used by parents', 'Changes in how parents and families live', and 'What to do after school'. 'First graders' awareness of elementary school' was analyzed as 'Awareness of Elementary school life', 'Awareness of peers', 'Awareness of homeroom teacher', and 'Awareness of learning'. As the conclusion of this study, we suggest that because the children have more free time than attending kindergarten, they need quality programs and support plans to support their first grade primary adjustment. Also, we propose a common problem facing first-year students: the difficulty of adjusting to study and support for how to study in an easier way.

We investigated the understanding of elementary school teachers on the current science issues. As a first step of the research, we choose 10 science issues which are influencing current society. Then we asked 119 elementary school teachers in Seoul, Inchon and Daejeon how important they think and how much they know the issues. As a result, we found that almost elementary school teachers know much on alternative energy, atomic bomb, nuclear power generation and global warming while they less know about high technology as Korean supersonic trainer($T-5^{TM}$) and Synchrotron radiation accelerator. Also we know that teachers take an interest on the articles about current science issues only for a while and forget to study on the issues for themselves. It is more important than whatever for the teachers to have exact understanding on current science issues in order to make civil society by acquiring the science literacy. Therefore elementary teachers and preliminary teachers should have a chance to study on current science issues. We suggest that teacher communities should be supported to improve the competency by cooperation.

2005년 12월에 정보통신기술교육 운영지침의 개정안이 발표되었다. 그러나 아직도 학교 현장에서는 이와 같은 개정안의 내용에 따라 제대로 교육이 실시되지 않고 있으며, "정보 처리의 이해" 영역의 내용은 가장 미흡하게 교육되고 있다. 따라서 본 논문에서는 2006년 6월 이후에 출판된 초등학교 ICT 교과서에서 "정보 처리의 이해" 의 내용을 분석하였다. 분석한 결과 많은 교과서가 정보통신기술교육 운영지침 개정안의 내용을 제대로 반영하지 않은 것으로 나타났으며 초등학교 교과서에서 소개하는 프로그래밍 언어도 너무 다양한 것으로 나타났다. 그러므로 초등학교 정보통신기술 교과서에 대한 개정이 시급하며 검정 시스템도 개선되어야 할 것으로 파악되었다.

In this paper the problem of calculating the probability that the responses of a wind-excited structure exceed specified thresholds within a given time interval is considered. The failure domain of the problem can be expressed as a union of elementary failure domains whose boundaries are of quadratic form. The Domain Decomposition Method (DDM) is employed, after being appropriately extended, to solve this problem. The probability estimate of the overall failure domain is given by the sum of the probabilities of the elementary failure domains multiplied by a reduction factor accounting for the overlapping degree of the different elementary failure domains. The DDM is extended with the help of Line Sampling (LS), from its original presentation where the boundary of the elementary failure domains are of linear form, to the current case involving quadratic elementary failure domains. An example involving an along-wind excited steel building shows the accuracy and efficiency of the proposed methodology as compared with that obtained using standard Monte Carlo simulations (MCS).

The purpose of this study was to evaluate the elementary students' knowledge, attitudes, and practice for food hygiene and safety. A self-administered questionnaire was developed and offered to 375 elementary school students throughout the Seoul region. The results of the survey were as follows: First, the knowledge, attitudes, and practice were not at satisfactory level. The scores of children's knowledge, attitudes, and practice were 67.42%, 3.83, and 3.81 out of 5 point scale, respectively. Second, knowledge, attitudes and practice levels were significantly different according to demographic characteristics. The lower grade-students had significantly higher scores for knowledge (p<.05), attitudes (p<.05) and practice (p<.01) than higher gradestudents, suggesting that food hygiene and safety education is more effective in younger students or that repeated education is needed for higher grade-students. Third, knowledge, attitudes and practice levels were significantly correlated each other. These results suggest that the education programs for food hygiene and safety should be developed for, as well as implemented in, lower elementary school grades.

This study presents an examination of the effects of the sub-factors of both self-control and school adjustment on smartphone addiction among a sample of elementary school students. The study is comprised of 93 5^th-grade students from x elementary school located in Seoul, Korea. A descriptive analysis, Pearson's correlation, and multiple regression analysis were performed, and the following two study results are presented: 1) Among the sub-factors of self-control, instant gratification positively predicts smartphone addiction. 2) Among the sub-factors of school adjustment, a student's adherence to school rules negatively predicts smartphone addiction. Based on these results, the implications for preventing smartphone addiction among elementary-school students are discussed.
