For years, Q1.5 (anthropomorphic test device for 1.5 years old infant) and Q3 (anthropomorphic test device for 3 years old infant) dummy protection has been improved considerably by the effort of EuroNCAP. ISOFIX strength of vehicle structure has increased and many child occupant protection tests have made child restraint system (hereafter CRS) optimized for child safety. However, from 2016, EuroNCAP changed the dummy which is used for the child occupant protection from Q1.5/Q3 to Q6/Q10 and these were also adopted in KNCAP from 2017. Therefore, a new method is required to secure the safety for older children In this research, child dummies were tested by using adult safety systems, and the different results from each adult restraint system were compared. Finally, dummies were tested with the CRS harness belt commonly used for infants, which has yielded significant result. In this research, mid-sized sedan and small SUV were used for the test. The researchers of this paper performed sled tests to correlate between the different adult safety belt system and child injury. Following the sled test, an actual vehicle test was conducted to gather the injury data of Q-dummy with the CRS harness belts. This paper will show the advantages of applying a pre-tensioner in the second row for child protection and the necessity of CRS which has its own harness belts to improve safety for older children.

Traffic accidents among children have been decreasing after the installation of yellow carpets. However, the explanatory power of the causal relationship between yellow carpet installation and traffic accidents is still insufficient. The yellow carpet effect was analyzed in greater depth using virtual reality (VR) simulation experiments in various situation that could not be evaluated in existing actual vehicle research studies due to difficulties or risks in implementation. A target site where an actual yellow carpet was installed was selected and, implemented into a virtual environment. Subjects were made to, were gaze measurement equipment and ride the simulator. The visual/driving behavior before and after yellow carpet installation was compared, and a t-test analysis was performed for statistical verification. All the results were found to be statistically significant.

본 연구는 다중이 이용하는 복합문화센터에서 피난설비 및 피난동선의 적합성 여부와 소방시설의 적정 유지관리방법에 관하여 연구하였다. 다중이 이용하는 복합문화센터와 같은 시설에서 화재나 비상시에 피난기구 및 피난동선의 적정성 여부와 소화설비의 적정한 설치 및 유지관리 실태를 파악하고자 하였고, 조사 결과 피난기구 및 피난동선의 구조적 문제 때문에 화재가 발생하면 많은 사람이 일시에 몰려들 경우 노약자와 어린이는 부상의 위험성이 높았고, 소방시설의 유지관리 시스템은 소방안전관리자의 전문성과 적정 유지관리시스템이 확보되지 않았으며 지하층에서 지상으로 완전 피난에 여러 가지 문제가 있었다.

주의력결핍 과잉행동장애는 미국에서 약 200만 명의 어린이에게 나타나는 심각한 만성 신경행동학적 장애이다. 주의력결핍 과잉행동장애 치료의 중심은 약물요법이다. 그러나 현재 환자의 약 30%는 주의력결핍 과잉행동장애를 적응증으로 갖도록 허가된 의약품들을 사용해도 적절한 치료효과를 얻지 못하고 있는 상황이다. Modafinil은 methylphenidate나 amphetamines와 같은 각성제와는 다른 약리학적 기전으로 중추신경계를 항진시킨다. 본 연구는 modafinil의 주의력결핍 과잉행동장애 치료효과에 대한 최신 지견을 얻고자, 1990년부터 2010년 3월까지 MEDLINE에 등재된 논문을 ADHD와 Modafinil이라는 MeSH terms로 검색하여 추출한 자료 중에서 대조군이 사용된 무작위 배정 및 이중맹검 임상연구 사례만을 선별하여 임상적 유용성을 평가하였다. 현재 modafinil은 주의력결핍 과잉행동 장애 치료제로 허가된 의약품은 아니지만 최근 여러 국가에서 시행된 연구들은 modafinil이 안전하고 효과적인 주의력결핍 과잉행동장애 치료제일 수 있다는 결과를 보여주고 있다.

In this paper, we propose iZone system for safe walking of children. The proposed system recognizes the state that a child is down a roadway as a dangerous situation. And then it informs the surrounding adults and guardians of the child in the event of a dangerous situation. The iZone system consists of the iZone device that attaches to a child's bag or clothing, the iZone app for children, the iZone server, and external beacons. The proposed system uses the ultrasonic sensor of the iZone device and the GPS coordinates and external beacons information by the children's smartphone to determine the dangerous situation. The proposed system uses external beacons to calibrate the GPS coordinates. Moreover, it determines whether the child is down the roadway in sidewalk by measuring the height difference between the roadway and the sidewalk using ultrasonic sensor.

The purpose of study was to improve the oral hygiene methods for early childhood. The author investigated the oral hygiene materials for early childhood and the oral hygiene methods used by 672 caregivers in Iksan city. The oral hygiene materials were oral tissue, finger brush, toothbrush sets according to the growth stages, electric toothbrush, child toothbrush, toothpaste sets according to the growth stages including eatable toothpaste, and child toothpaste, The rate of caregivers who used each materials was 62.5% for oral tissue, 70.9% for finger brush, 55.9% for toothbrush sets, and 87.4% for eatable tooth-paste. 79.0% of caregivers began toothbrushing from first eruption and about 1 year of age. The rate of swallowing toothpaste was 22% before 48 months, 9% from 48 to 59 months, and 3% after 60 months. The rate of children brushed by caregivers was 52% before 48 months, 42% from 48 to 59 months, and 26% after 60 months. The basic method of oral hygiene management for early childhood is to remove the dental plaque by toothbrushing, and the toothpaste may be used. Suffocation, accidental swallowing, and injury to the throat must be avoided. Generally, the fluoride toothpaste is not recommended before 3 years of age. The least amount of fluoride toothpaste should be used and caregivers should supervise children to prevent the swallowing of toothpaste.

The problem of evacuating pedestrians from a room or channel under panic conditions is of obvious importance in daily life. In recent years, several computer models have been developed to simulate pedestrian dynamics. Understanding evacuation dynamics can allow for the design of more comfortable and safe pedestrian facilities. However, these models do not take into account the type and state of mind of pedestrians. They deal with pedestrians as particles and the state of mind as a social force, which is represented by conservative and long-range interactions between individuals. In this study, I used the lattice model proposed in my previous study to explore the evacuation behavior of pedestrians with morality. In this model, three types of pedestrians are considered: adults, children, and injured people. Collisions between adults and children result in injured people. When the number of injured people continuously in contact with each other reaches a given value k, the injured people are removed from the lattice space. This situation is the same as that in which pedestrians start stepping over injured people. This behavior was interpreted as the morality of pedestrians. Simulations showed that the evacuation showed down and eventually became jammed owing to the injured people acting as "obstacles" in relation to the morality k.

The comprehensive natural disaster reduction plan, the highest plan in the disaster prevention field, was implemented by local governments. second plan is currently being formulated. In order to minimize human and property damage, structural and non-structural measures for each of the nine disaster types are established and implemented for 10 years. Structural measures are based on engineering and quantitative analysis, and the criteria for setting reduction measures are clear. Non-structural measures, however, currently lack the set criteria. the basic disaster and safety management law included the safety vulnerable class in 2018. Currently, the safety vulnerable class of the detailed establishment criteria of the comprehensive natural disaster reduction plan is being established, including children, the elderly, and the disabled. However, due to the lack of data securing and database construction by local governments, it is difficult to prepare a location map for establishing reduction measures for the safety vulnerable. Therefore, in this study, OPEN API data of the safety vulnerable class were collected and statistical information and GIS of SGIS information services were used. The distribution diagram of the safety vulnerable class in Samcheok, Gangwon-do, which is a sample area, and the distribution diagram of the safety vulnerable class in units of the output area (OA) in Geundeok-myeon were prepared.
