The purpose of this study was to examine the relationship between snack food intakes and dental caries in 661 Korean elementary school children. After each meal, 59.6% of the surveyed children ate snack foods, in particular, they ate snack heavily after lunch. The snack food items causing dental caries contained high levels of sugar and were convenience foods, which the children had preference toward. In addition, the intake frequency of snack foods substituted for meals was greater than 54%. Based on the results, the eating behaviors of children are in need of correction, and nutrition education on snack foods inducing dental caries is required.

The flying-disc game has started since 1940. It has been spreading rapidly in Korea since 2007, mainly in elementary schools. Additionally, as sports science has been developed, research on flying discs has been continued to build a monitoring system for technological improvement and efficiency. In this paper, we acquire information on the user's flying-disc using 9-axis motion sensor and GPS. Then we propose a method for wireless transmission using Bluetooth 5.0. Specifically, the HW platform was designed and implemented not only to monitor a real-time data but also to compare and analyze rotational speed, flight trajectory, and a count of disc rotation through post-processing.

Purpose: This study was conducted to investigate the factors affecting health promotion behaviors in late school-aged children by establishing a hypothetical model based on the planned behavior theory. Methods: From July 19 to August 31, 2017, 460 questionnaires were distributed to fifth and sixth graders at three elementary schools in Korea, of which 318 were ultimately analyzed. Results: All the fit indices were shown to be appropriate, indicating satisfactory fit. In the final model, six of the nine paths included in the hypothetical model were supported. Specifically, perceived behavioral control had the most influence on intention, followed by subjective norms, self-esteem, and health knowledge. Intentions were the most influential factor for health-promoting behaviors, followed by self-esteem and health knowledge. Subjective norms, perceived behavioral control, and self-esteem explained 57.6% of intention to engage in health promotion behaviors and 61.7% of variation in health promotion behaviors was explained by health knowledge, self-esteem and intention. Conclusion: The findings of this study provide support for a model that can be used to facilitate the practice of health promotion activities in children in the later years of school age.

This study analyzed the substitute behavior of mothers of infants or elementary-school-aged children in terms of consumption. For this study, in-depth interviews were conducted with women residing in the Seoul metropolitan area who show significant interest in their children. The interviews were analyzed based on the grounded theory. The findings of this study are as follows. First, mothers show substitute behavior for their children's appearance. The younger the children, the more substitute consumption exhibited by mothers. As children grow older and are able to choose what to wear, mothers show less substitute behavior tendencies regarding appearance management. Second, mothers tend to exhibit substitute behavior regarding their children's academic achievements. Mothers hope their children will be more successful than themselves were or will achieve the dreams that they failed to accomplish, which drives substitute behavior. Mothers affectionately provide children with financial support so they can obtain academic achievement and they hope their children will have successful occupations in the future. Third, mothers who are not satisfied with their appearance and have low self-esteem are more likely to exhibit substitute behavior with their children. This study will be helpful in understanding mothers' motivation and psychological factors regarding the support of their children.

목적: 최근 이명의 발생률이 증가하고 있으나 이명에 대한 정확한 원인 발견이 어려운 실정이다. 한국의 경우도 예외는 아니며, 사회경제적 상태에 따른 이명여부를 분석하고자 한다. 방법: 국민건강영양조사 제 5기(2010-2012)의 원시자료를 이용하였으며, 연구 대상자인 40세 이상 12,041명을 다중 로지스틱 회귀분석을 실시하였다(95% CI). 결과: 40세 이상 중년인구의 사회경제적 상태에 따른 이명여부는 통계학적으로 유의한 차이가 있는 것으로 나타났다. 이명의 발생여부는 연령이 높을수록(p<.0001), 직업군에 따라서(p<.0001), 대사증후군이 있는 자(p<.0001), 교육수준이 낮을수록(p<.0001), 기초생활수급자(p<.0001), 배우자가 없는 자(p<.0001), 스트레스가 많을수록(p<.0001), 우울증이 높을수록(p=.0034) 이명이 발생하였다. 회귀분석 결과 여성의 경우 대상자의 학력이 초등학교 이하인 그룹에서 교차비가 높았으며(OR:1.784, 1.322-2.408) 소득이 하위계층인 그룹에서 교차비가 높았다(OR:1.591, 1.293-19.58). 하지만 남성의 경우에는 유의한 결과가 나오지 않았다. 결론: 본 연구는 40세 이상 중년인구의 사회 경제적 상태에 따른 이명여부를 파악함으로써 남성보다 여성에서 사회경제적 수준에 따라 이명여부에 영향을 많이 받는 것을 밝혀낸 것에 연구의 의의가 있다.

Recently, the intelligent video surveillance technology has become able to provide various services such as predictive surveillance that have not been provided previously. Securing the security of the intelligent video surveillance is essential, and malicious manipulation of the original CCTV video data can lead to serious social problems. Therefore, in this paper, we proposed an intelligent video surveillance environment based on blockchain. The proposed scheme guarantees the integrity of the CCTV image data and protects the ROI privacy through the edge blockchain, so there is no privacy exposure of the object. In addition, it is effective because it is possible to increase the transmission efficiency and reduce storage by enabling video deduplication.

Purpose: This study aimed to investigate factors affecting handwashing practice among elementary school students by assessing the perception of coronavirus disease-19 (COVID-19) and characteristics related to knowledge, attitude, and practice of handwashing. Methods: The cross-sectional study design and an online self-reported survey were used in this study. The subjects were 211 elementary students at a school located in G province, Korea. Data were collected from January 4 to 8, 2021. The data were analyzed using SPSS version 25.0. Results: Mean scores for knowledge, attitude, and practice of handwashing were 17.09 (out of 20), 21.15 (out of 24), and 27.51 (out of 33), respectively. There were significant positive correlations between the perception of COVID-19 and knowledge of handwashing (r=.23, p=.001), between knowledge and attitude toward handwashing (r=.45, p<.001), between knowledge and practice of handwashing (r=.18, p=.010), and between attitude and practice of handwashing (r=.28, p<.001). The factors influencing handwashing practice were handwashing frequency at home (β=.39, p<.001), handwashing frequency at school (β=.18, p=.006), and attitude toward handwashing (β=.15, p=.026), which explained 34.2% of the variance. Conclusion: These results suggest a need to raise awareness of the importance of handwashing and develop an education program for infectious disease prevention.

Purpose: Based on the Health Belief Model, this study aimed to identify factors influencing on COVID-19 vaccination intention of mothers with elementary school children by examining the relationships between perceived susceptibility, perceived severity, perceived benefit, perceived barrier, cue to action, and perceived self-efficacy. Methods: Mothers with elementary school children were recruited from three elementary schools. An online survey was conducted of 130 mothers in November, 2021. Results: As a result, the factors influencing on vaccination intention were perceived self-efficacy (β=.33), perceived susceptibility (β=.18), perceived benefit (β=.16), and perceived barrier (β=-.17). Conclusion: Based on our findings, there is a need to develop a tailored nursing intervention that enhances perceived self-efficacy, perceived susceptibility and perceived benefit while decreasing perceived barrier in order to improve vaccination intention.
