This study was conducted to determine the content of inorganic metals in soft drinks distributed locally in markets.6 trace metals (Fe, Ca, Zn, Na, Mg, and K) were detected in 16 kinds of drinks,80 samples. The average concentration of inorganic metals in vegetable drinks was relatively higher than that of mixed drinks or carbonated drinks. The concentration of calcium, which is advisable inorganic metals for the growth of skeleton and the prevention of osteoporosis, hypertension, was very high and needed to be careful for the consumer who is suffer with lithiasis. Although carbonated drinks are very popular with the children and adolescence owing to the unbalance of the intake of Ca and P, habitual drinking could cause obstruction in skeletal growth and metabolism of Fe, Cu, and Zn. So, it is suggested that more practical study is needed fur the intake of inorganic metals.

In this paper, we plan to design and manufacture a new sleeping child check system using image and PIR sensors. Therefore, it plans to implement a system that can prevent in-vehicle accidents that can occur due to presence of human and certain temperature inside the vehicle by collecting data from PIR sensors and temperature sensors with the main control device based on Arduino. In addition, the values of sensors can be linked with Bluetooth communication or Wi-Fi communication to send information to the mobile phone, and the sensor values can be printed by texting on the screen. It also plans to use raspberry pie and camera modules to build a display and smartphone streaming service inside the vehicle. Through this, the objective of this study is to prevent safety accidents in school vehicles by making experiments and research in this paper recognize 100% inside the vehicle with the quantitative goal of PIR sensors.

Objectives: More than 80% of unintentional injury was related to risk-taking behaviors involved in child accidents. Therefore, diverse care and concerns on safety should be provided from teachers as well as parents to build child safety behaviors. The purpose of this study was to identify the effects of safety concerns from students, teachers, and parents on elementary students' safety behaviors in Korea. Methods: The 5th and 6th grade students participated in this study in 14 elementary schools in Korea and the total number of students was 1,033. The study schools were selected by the stratified cluster sampling method throughout 7 metropolitan areas in Korea. Data were collected by the self-administered survey and the questionnaires were delivered to the vice-principals of the designated schools by ground postal service and the vice-principals conducted survey data collection. The questions on students' safety concerns, teachers' safety concerns, parents' safety concerns, safety practices, safety education, and demographics were included in the survey. All survey responses were encoded into SPSS program and t-test, ANOVA, and multiple regression analysis were utilized. Results: The students taking accidents one time more per year were more than 60% and the two thirds of them recognized that their accidents were due to their risk behaviors. Parents' education on safety practices was more frequent than teachers' education; furthermore, teachers' concerns on safety behaviors were poorer than students' or parents' concerns. In terms of safety behaviors, the scores of fire and home-related safety behavior were high but the scores of traffic and bicycle, in particular, helmet wearing practice were low. Three concerns from students, parents, and teachers all were significantly related to children's safety behaviors. Conclusions: In conclusion, safety concerns from the close networks are the important indicator of child safety behaviors and, the safety training programs, therefore, for parents and teachers as well as for students need to be developed for improving children's safe behaviors.

This study examined the effects of 'Dietary education for children's health UP' (DECHUP) on the changes in knowledge, attitudes, and practice (KAP) of nutrition and food safety in $5^{th}$ grade elementary school students in Incheon. The DECHUP program was conducted from May to October 2018 and consisted of education and activities focusing on the children's levels of understanding. Data were collected before, immediately after, and 6 weeks after DECHUP using the same method. All data were analyzed using SPSS ver 20.0. The level of knowledge and attitudes of the subjects to nutrition and food safety was significantly higher after than before DECHUP, but the attitude of boys did not show any significant difference after 6 weeks. Although there were no significant differences in the behavior for nutrition in the practice of the subjects, there were significant positive changes in the behavior of food safety. The higher the satisfaction of DECHUP, the more positive the change in knowledge, and the more positive the attitude and practice behaviors. Therefore, DECHUP has positive effects on the KAP of the subjects, and it will be helpful for elementary school students to form desirable eating habits if it can be carried out periodically and continuously.

The Korean government recently has focused on variety of policies to promote the use of bikes to control the emission of carbon. However, bike facilities with no regard to the safety and comfort of bike drivers has made inefficient bike roads. Also, the accidents related to bikes have increased rapidly. This study proposes the proper types of the bike roads considering land use and bike driver characteristics. The elements classifying the bike driver characteristics are driven through oneway ANOVA and cluster analysis. It is found that the types of the bike roads can be classified by the ratio of child and elderly bikers and the ratio of heavy trucks. Also, the each type is characterized by the land use types such ad residential, commercial and industrial areas through cluster analysis. According to the results of the cluster analysis, installation of bike roads in residential area needs to consider convenience and safety simultaneously. It is also found that convenience should be the most considerable factor in commercial area. Lastly, safety should be considered in industrial area. Recommended methodology and bike road type based on the land use and bike driver's characteristics can be useful to develop bike-friendly environments and increase mode share of bikes.

Marker pens belong to school things that are controlled by the regulation system called safety confirmation under special act on the safety of products for children with the formaldehyde criteria of 20 mg/kg. With nine marker pens available commercially, formaldehyde in marker pen ink was analyzed by present test standard where marking on a fabric swatch with a pen and extracting the swatch in water and derivatization with Nash reagent followed by UV/Vis spectrophotometeric measurement (Nash-UV/Vis method), giving not detected results or a false positive result in case of a colored water extract. However, the contents of formaldehyde in ink of nine marker pens were determinded to range between 3.2 ~ 93.2 mg/kg with three results above the safety criteria of 20 mg/kg by HPLC/DAD measurements on DNPH derivatives of formaldehyde (DNPH-HPLC/DAD method) in ink dissolved directly in water using an ultrasonic bath. Therefore, the DNPH-HPLC/DAD method with the extraction of ultrasonic dissolving ink in water is proposed as a proper method for analyzing formaldehyde in ink. The proposed method has advantages of lower detection limit and accuracy with colored extracts as well as a simple and fast extraction. The accuracy and precision of this method was estimated to be 90.1 ~ 105.4 % and 0.6 ~ 3.3 %, respectively by spiking tests in the ranges of 20 mg/kg and 40 mg/kg using matrixes such as highlighter pen ink, board marker ink, chalk marker pen ink and painter marker ink.
