Currently, systems for finding missing children are composed of using communication between a QR code and RFID chip, as the use of a smartphone. However, the current systems for finding missing children have limitations in that children can only be found if there are people in the surrounding area; there is an economic burden on parents required to purchase a smartphone for their children; along with difficulties in finding the missing children without the assistance of those in the surrounding area in critical situations such as a kidnapping, due to the limited duration of the battery life. In order to solve such problems, approaches need to be made from two perspectives: having someone in the surrounding area; and absence of anyone in the surrounding area. This thesis is centered on the development of a IoT (Internet of Things) system for finding missing children that combines two methods, namely, the method of finding missing children without a guardian in the surrounding area -within the limited space in which AP is installed by using a beacon and open source hardware being highlighted as the IoT technology - and the method of finding missing children with the smartphone application in which each individual becomes the Access Point (AP). The Main purpose is to provide accurate information of missing children's location for the 2situations and it is found that the accuracy of smartphones APP is 97.7% and security device AP is 91.1%.

Objectives Children are one of the most vulnerable populations to the impact of disasters. We aimed to examine children's mental health in the area affected by the Hebei Spirit oil spill accident on December 7, 2007. Methods A cross-sectional questionnaire survey was conducted using the Korean versions of the Children's Depression Inventory and State Anxiety Inventory for Children on 1,362 children attending elementary schools in the affected area. The information on distances between the nearest contaminated coastline to the child's residential house or attending school were obtained using a web-based map by inputting two address points. The symptom risks of depression and state anxiety were estimated by multiple logistic regression analyses adjusted for age, gender, and other covariates. Results Children with the closest distance (in the fourth quartile) to the school from the contaminated coastline showed a significantly higher symptom risk of depression compared to those with the farthest distance (first quartile)(odds ratio, 2.73; 95% confidence interval, 1.40-5.33), while there was no significant association between anxiety symptoms and distance. Conclusions Children, a vulnerable population for mental health impact by the oil spill accident, should be included in mental health programs in the community along with their family as victims of the disaster.

The cello·tape anal swab specimens from 936 primary school children in Seoul, 308 primary school children in a rural area and 92 children in Nanjido, were examined for Enterobius vermicularis eggs. Out of 936 specimens from a primary school in Seoul, E. vermicularis eggs were detected in 114 specimens, the egg detection rate being 12.2%. In 308 specimens from a primary school in a rural area,77 (25.0%) were positive for 5. vermicularis eggs. Among 92 specimens from Nanjido children in Seoul, egg Positive rate of E. vermicularis was 28.3%. The egg detection rate of primary school children in Seoul was significantly lower than that of primary school children in a rural area and of Nanjido children. The egg detection rate in boys was lower than that of girls. As the age of children increased, the egg detection rate decreased.

Infection by hepatitis B virus is one of the major health problems of this nation. HBsAg positive rates of general population and school children were known to be as about 8 percent and 3.9 to 5.9 percent respectively. To study the incidence rate of hepatitis B infection in school children of rural area, author had examined 475 school children of relatively isolated agricultural area for baseline prevalence of hepatitis B virus serologic markers and followed up 415 school children during 10 months to determined the frequency of serologic conversion. The major results are summarized as followings: 1) Among the 278 susceptible children who were followed up, 26 had seroconversion for HBsAg or Anti-HBs. Therefore, the cumulative incidence rate during 10 months is estimated 9.4%. 2) The incidence rate of hepatitis B infection tends to increase with age (6-9yrs: 3.2%, 10-14yrs: 9.5%, 15-17yrs: 18.9%), and the incidence rate in male (13.0%) was higher than in female (5.7%). 3) The incidence rates of hepatitis B virus infection were not different statistically among three economic classes (The rates of lower, middle and higher class were 11.8%, 7.1% and 10.5%.). 4) The incidence rates of hepatitis B virus infection were not different statistically between visitors and non-visitors of clinic or hospital, dental clinic, persons received IV and not received IV, and persons with familial history and without familial history of liver diseases. Therefore all of these factors were not identified as risk factor of hepatitis B virus infection. And the transmissibility within the class of school was not recognized, too. 5) Among the 25 children who were HBsAg positive when enrolled, 15 (60%) were still HBsAg positive, who were identified as chronic carrier 15 of 415 school children were chronic carriers, then chronic carrier rate was estimated 3.6%, and there was no difference between sexes. 6) Of 38 children who had been Anti-HBs positive when enrolled, 5 (13.2%) lost Anti-HBs. Therefore, the loss rate of Anti-HBs per year is estimated to be 15.8%.

This Study was carried out to find out regional differences about dietary life and factors associated with meal of school children and adolescents between urban and rural area. Forty students from each of the nationwide 51 schools of three different levels(elementary, middle and high school) were surveyed by self-developed questionnaires. Total of 1,886 questionnaires (1,243 from urban and 681 from rural) were collected and distribution of subjects was 544 from elementary school, 661 from middle school, and 681 from high school. The results were summarized as follows. BMI and degree of satisfaction on body weight of elementary and middle school subjects were not significantly different between urban and rural area. But there were significant regional differences in $BMI(urban\;21.2{\pm}3.0,\;rural\;20.5{\pm}2.8,\;p<0.05)$ and degree of satisfaction on body weight of high school subjects(p<0.001). Elementary(p<0.01) and middle school(p<0.05) subjects in urban area had exercised more frequently than those in rural area. Regularity of having breakfast was not significantly different between urban and rural area at each of three different levels of school. Most subjects(urban 92.2%, rural 92.1%) had lunch regularly by virtue of school lunch service. Regularity of having dinner of elementary(p<0.01) and high school subjects (p<0.01) was significantly different between urban and rural area. Reason for skipping dinner of high school subjects was significantly different between urban and rural area (p<0.05). The most delicious meal was dinner for 51.8% of the urban high school subjects and lunch for 51.7% of the rural subjects. Only one third had intention of participating in school breakfast program regardless of region and levels of school. The findings suggested that nutrition education programs for school children and adolescents include different strategy according to region and levels of schools.

The purpose of this study is to provide the guideline of the outdoor space of residential land development district for children's outdoor activites. This study was accomplished by the valuation of the physical environment of 5 residential land development districts, the analyzation of behavioral mapping about children's outdoor activities, and the analyzation of satisfaction and the consciousness of 190 residents(parents) & 230 children. Especially, outdoor spaces were divided into 6 parts (play space, education facility, commercial facility, green space, and empty space & parking lot). And than, 6 outdoor spaces were valuated about the physical characters such as accessibility, network, safety, variety, functional, natural elements. Also, the survey for residents and children's consciousness were used the Likert scale. According to the result of this study, many parts of the housing area were not good for children's activities, and resident's satisfaction was low. In the sample areas, negative factors were car and motorcycle. And many residents were pointed out the lack of natural elements, variety, and safety of outdoor space in dwelling area. Finally, this study suggested the guideline children's activities based on the result of analyzation of valuation, behavioral mapping, and survey.
