실종아동문제는 한 가정의 문제로 끝나는 것이 아니라 사회문제로 발전할 수 있다는 데에 그 심각성이 있다. 하지만 실종아동문제에 대한 사회적 관심은 초보적인 수준에 머무르고 있다. 본 연구의 목적은 실종아동문제에 대한 사회적 관심을 불러일으키기 위해 아동실종의 사회경제적 비용을 추계하는 것이다. 전체적으로 1명의 장기실종아동이 발생하였을 경우, 약 5억 7천만원 정도의 비용이 발생하였다. 직접비용은 약 6,532만원으로 전체의 11.5%였으며 간접비용은 약 5억원으로 전체의 88.5%였다. 이는 실종을 예방하는 것이 가장 중요하지만, 실종 이후에는 단기간 내 찾기가 매우 중요함을 보여주고 있다. 본 연구결과를 통해 실종으로 인한 사회경제적 비용이 계산되어 실종에 대한 국민의 관심을 유발할 수 있고 예방에 대한 적정 투자비용에 관하여 자료를 추산할 수 있으며, 결과적으로 실종 예방에 대한 적극적인 국가적 투자를 유인할 수 있을 것이다.

미아 발생 및 아동 유괴 문제 등 아동에 대한 각종 범죄는 오래 전부터 사회적인 문제로 지적되고 있다. 하지만 이러한 문제를 해결하기 위한 방안은 극히 미비하다. 미아 통계에 따르면 해마다 3,000명에 달하는 미아가 발생한다. 본 논문은 밀집 공간에서 미아 발생률을 낮추는 것을 목표로 모바일 LBS를 이용한 미아 발생 예방에 관한 연구를 소개한다. 첫째, 아이의 인적 사항 및 부모의 연락처를 입력으로 받는다. 둘째, 구글 맵 API를 이용하여 위치(부모의 위치, 아이의 위치) 정보를 얻는다. 셋째, 얻어 온 위치정보에 아이와 부모의 인적 사항을 표기한다. 향후 연구에서는 SNS를 기반하여 아이의 위치정보와 부모의 위치정보를 SMS로 전송하는 연구를 진행할 것이다. LBS와 SNS를 이용한 미아 발생 예방 시스템은 머지않아 도래할 유비쿼터스(Ubiquitous) 사회에서 미아 발생률을 줄이는데 큰 기여를 할 것으로 기대한다.

Objectives: The water fluoridation program has been implemented since 2008, in a region of Geoje City. This study aimed to evaluate the effectiveness of the water fluoridation program on caries prevention in the permanent dentition. Methods: Evaluation surveys were conducted on 8-, 10- and 12-year-old children in the fluoridated and non-fluoridated regions of Geoje City, in 2015. The survey included 834 children from the fluoridated regions and 703 from the non-fluoridated regions. The data obtained from the survey were analyzed using the IBM SPSS statistical package version 23.0. The effectiveness of community water fluoridation in caries prevention was estimated by the differences in the decayed, missing, filled teeth (DMFT) and decayed, missing, filled surfaces (DMFS) scores, between the program and control groups. The mean numbers of fissure-sealed teeth and surfaces were adjusted to reduce their confounding effect. Results: The mean DMFT and DMFS scores (0.69 and 0.91, respectively) of 10-year-olds from the fluoridated regions, after adjusting for the numbers of fissure-sealed teeth and surfaces, were significantly lower than those of the 10 year olds (DMFT: 0.95, DMFS: 1.32) from the non-fluoridated regions. The effectiveness of water fluoridation on caries prevention in the permanent dentition, estimated based on the differences in the mean DMFT and DMFS scores, adjusted for the number of fissure-sealed teeth and surfaces, between the program and control groups of 10-year-old children, was 27.4% and 31.1%, respectively. Conclusions: These results suggest that the effectiveness of water fluoridation on caries prevention in the permanent dentition, in Geoje City was so high that this program should be implemented in other regions in Korea as well.

Since lost child occurs frequently around us and there is a possibility of leading to an accident or a crime subsequently, it is necessary to study and have a plan for preventing child loss in advance. However, the preceding studies do not systemize the causes of child loss by places or situations, and the policy focuses only on the countermeasures afterward instead of prevention. In such perspective, this study derived the causes of child loss through the analysis of 202 cases by the bottom-up method. In addition, the causes were analyzed by dividing them into as negligence of guardian, breakaway of child, and environmental characteristics. As a result, it is found that children get lost by complex reasons usually with two or three causes combined together. And children got lost when guardians were not able to pay attention to their children, or when children moved away from their guardians. Furthermore, the environmental characteristics act as the catalyst by arousing child loss or making it more difficult for guardian to find the lost child. As a fundamental research, this study may be helpful in developing a environmental design certification system for preventing child loss in advance.

어린이들은 성인에 비해 힘, 상황 인지 능력, 상황 판단 능력 등이 부족하기 때문에 성인 및 관련단체 또는 국가로부터 보호받을 권리를 제공 받아야 한다. 현재 어린이집에서 교사 1명이 관리하는 어린이는 적게는 3명에서 많게는 20명가량 이며 관리해야하는 어린이가 많으면 많을수록 어린이를 모두를 신경 쓴다는 것은 교사 입장에서 매우 어려운 일이 아닐 수 없을 것이다. 특히 개방된 공간에서 이루어지는 원외 활동 시에는 원내의 비해 어린이들의 활동범위가 넓어지고 인솔 교사의 통제에 따르지 않는 어린이가 발생할 수 있기 때문에 교사들의 시각에 의존한 어린이 통제 및 관리는 한계가 존재하게 된다. 이에 본 연구에서는 상호통신이 가능한 휴대용 디바이스를 사용하여 어린이와 인솔 교사 간의 위치 또는 간격을 시스템화하여 어린이들에게 안전을 제공하고 보호자 및 교사들에게 편리함을 제공할 수 있도록 IoT 단말기 및 시스템을 설계 및 구현 하였으며 이를 통해 유아의 안전에 기여할 수 있기를 기대한다.

Demand for appropriate health care has gradually increased in Korea. In addition, developments of community- and school-based oral health programs have also focused oral health care for the oral health promotion. Especially, school-based oral health programs are the underpinnings of promoting oral health and preventing oral diseases among schoolchildren. School-based oral health programs have had three major components: oral health education, oral health services, and a healthful environments. These included oral health education(one-to-one communication, group communication, and use of mass communication), oral examination, fluoride mouthrinsing, pit-and-fissure sealants, fluoride gel application, mechanical plaque control, and chewing xylitol candy. In this study, we evaluate the effects of oral health programs among primary schoolchildren by comparing the oral health knowledge, oral health behaviors, and perception of caries prevention procedures. Data for this study were obtained from 699 primary schoolchildren at the two primary school in Daegu, Korea. One is experimental group, N primary school, that was established school-based oral health center under supervision of Nam-gu Public Health Center, the other is control group, N' primary school, that was yet to establish school-based oral health center. We surveyed children's oral health knowledge and behaviors, and perception of caries prevention procedures using self-administrated questionnaire and then analyzed differences of each item among two groups. The brief findings of this study were summarized as follows. There are several advantage to a comprehensive school-based oral health program. (1) School-based oral health programs facilitate and increase the effectiveness of teaching oral health subjects. (2) Schoolchildren are available for prevention or treatment procedure. (3) School-based oral health center may be less threating than private dental clinic. (4) With comprehensive school-based oral health programs the decayed, missing, and filled teeth(DMFT) of schoolchildren should demonstrate a substantial and steady decrease over time(Choi et al, 2004). In conclusion, treatment is not the answer to solving children's oral health programs; rather primary prevention is the key. Many countries and communities are focusing on hoe millions of underprivileged children can be provided with health care. Schoolchildren gain the knowledge and behaviors to attain and maintain good oral health in schools. For these reasons, the role of school-based oral health center is not only important but also a necessity.

Parental smoking status and smoking environment do not only affect children's health through exposure to nicotine, but are also related to children's smoking attitude, intention and knowledge of smoking. Since this study was conducted to examine a relationship between family members smoking and smoking attitude, intention and knowledge of their children, little is known about psychosocial factors influencing smoking among Korean preschool children. This study aimed to determine the psychosocial factors (sociodemographic factors, education for smoking cigarette, knowledge about smoke cigarette) influencing smoking attitude and smoking intention, with a purpose of providing directions for future education programs for Korean preschool children. A cross sectional sample of 840 children, ages 4-7 years, living in a rural district were interviewed during August 6 - November 14, 2003. Among them, 834 children whose missing data were less than $10\%$ were included the analysis. The independent variables included sociodemographic characteristics and education for smoking cigarette, while the dependent variables were knowledge about smoking, the children's smoking attitude and their intention of smoking. The data on sociodemographic characteristics were analyzed using descriptive statistics including frequency, percentage, mean, and standard deviation. The correlations between the independent variables and attitude and intention of smoking were analyzed using chi-square test, t-test, and logistic regression. The results of this study were s follows. The factors that were found to be significantly correlated to smoking attitude include mother's smoking $(x^2=4.86,\;p=.03)$, grandmother's smoking $(x^2=5.56,\;p=.02)$, and knowledge of smoking cigarette $(x^2=-5.13 p<.01)$. The factors that were significantly correlated to the intention of smoking include gender $(x^2=.08,\; p=.02)$, education for smoking$(x^2=17.65,\;p<.01)$, mother's smoking $(x^2=19.05,\; p<.01)$, grandmother's smoking $(x^2=17.67,\; p<.01)$, and knowledge$(x^2=-2.17,\;p=.03)$. The children who had non smoking mother were more likely to have negative attitude (OR=2.29). The children who had a higher knowledge about smoking were more likely to have negative attitude (OR=1.58). The findings suggest that a smoking prevention program specific for preschool children is necessary to prevent early onset of smoking. The findings also suggest that the program should involve children's family members who influence their smoking attitude and intention.
