As the use of children's school buses increases, accidents caused by the negligence of school bus drivers and ride carers have also increased significantly. To prevent such accidents, the government is coming up with various policies. We propose an accident prevention and safety management system for children's school buses. Through this system, bus drivers can easily check whether each child is seated and whether the seat belt is used, so it is possible to quickly respond to children's conditions while driving. With the ability to recognize faces by analyzing camera images, children can use a seat belt that is automatically adjusted to their height. It is therefore possible to prevent secondary injuries that may occur in the event of a traffic accident. In addition, a sleeping child-check system is provided to confirm that all children get off the bus, and a text service is provided to inform parents of their children's locations in real time. Based on Raspberry Pi, the system is implemented with cameras, pressure sensors, motors, Bluetooth modules, and so on. This proposed system was attached to a bus model to confirm that the series of functions work correctly.

Purpose: To analyze the health concept and health behaviors in school children through the interview on study groups. To obtain the subjective data for health concept and health behaviors in school children. Methods: This study is a qualitative study applied the interview of study groups. Participants are 12 people and two groups- each of them is 3 males and females, which are $6^{th}$grade of elementary schools located in Seoul city and Kyung-gi Province. The interviews were conducted twice on November in 2005. Results: 83 items are significantly related in health concept for school children. The results are the following; 1) the significant health concept for school children is 15 items and there are 5 areas- strength, comfort, action, compatibility and normal life. 2) the actual health behaviors are 23 items and there are 8 areas-exercising, associating, mentally resting, laughing, releasing stress, well sleeping, well eating and receivingcheck-up. 3) the needed and the wanted health behaviors are 45 items and there are 12 areas-well eating, well cleaning, exercising, playing, comforting, resting, staying in familiar environment, receiving regular check-up, abstaining, associating, enjoying hobbies, and forming environment & facilities. Conclusion: For health concepts, school children consider significantly not only physical activities but also social and mental activities and environment. They also want exercising, abstaining, eating well, checking-up, enjoying hobbies, forming environment & facilities with various activities.

Purpose: The purpose of this study was to describe health problems and psychosocial adaptation in children with cancer and to determine the relationship between these two variables. Method: The data were collected from parents of 61 children with cancer, aged 4-11 years at one university hospital in Seoul. The instruments for this study were the Korea Child Behavior Check List (KCBCL) and a physical symptom checklist developed by the researchers. Result: The major health problems were coughing, sleeping disturbances, fatigue and weakness. The total behavior problem score for children in the cancer group was higher than the score for those in the norm group. The scores on the scales for withdrawal, somatic complaints, social immaturity, and internalizing problems were higher in the children with cancer compared to normative findings. Scores on social and school competence in the cancer group were lower than the norms for healthy children. The relationship between health problems and psychosocial adaptation was significant in the subscales of withdrawal, anxiety/depression, internalizing problems and social involvement in the off therapy group. Conclusions: This study shows the various areas that need further study in caring for children with cancer.

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.
