Childhood injuries are the primary cause of death and disability among children aged 5 to 14. Consistent practice of learned safety behaviors can reduce the occurrence of severe injuries among children. However, safety behavior concern is low among Korean-American children specifically and American children, in general. The objective of the study is to evaluate the impact of an unintentional injury prevention curriculum, Risk Watch among Korean-American children. A quasi-experimental design with a nonequivalent control group was used for the designed of the study. Two intervention and two control Korean schools in Atlanta participated in this study. The intervention consisted of weekly lessons in traffic, bicycle, pedestrian, and fire safety. One hundred and two students completed a pre-test and a post-test. The main outcomes were safety behaviors (seat belt use or helmet use), behavioral intentions, and safety knowledge. Analysis of covariance was used for the statistical analyses. Strong intervention effects were found for increasing knowledge of all safety topics in the intervention group. Additionally, statistically significant intervention effects were detected for increasing seat belt and helmet use, as well as behavioral intentions of wearing a seat belt and wearing a helmet, among pre-kindergarten and kindergarten students. For students in grades 1 and 2, intervention effects were found for increasing helmet use. Among students in grades 3 to 8, the intervention group showed statistically significant increases for seat belt use. Limitations of the study and recommendations for modifying and supporting unintentional injury prevention programs for school children are discussed.

There are many accident risks in logging operation of forestry such as struck by felled trees and caught in, under, or between felled trees. These accidents are primarily occurred by not keeping a safe distance between workers. According to the forestry safety instruction, workers are not supposed to go into the safety zone which is a circle with a radius of more 2 times the height of felling tree. However, this rule does not keep because of poor safety consciousness, poor sight and extreme noise of logging operation machines. This problem causes many major accidents every year. To solve this problem, we made forestry safety helmets based on IoT technology. These helmets have functions to make a visual and an acoustic alarm signal when reach the distance between workers within 20 meters. We developed the algorithm to operate the helmet's functions and conducted tests to check the functions. As a result of tests, we assured the normal system operating conditions.

안전모는 다양한 산업현장에서 머리 보호를 위해 착용되는 보호구로 법적으로도 착용이 의무화되어있다. 그러나, 안전모 착용에 따른 불쾌감 및 생리적 부담은 작업자들이 착용을 꺼려하는 주된 원인이 된다. 본 연구에서는 이 문제를 해결하기 위한 하나의 방안으로 안전모에 냉매팩을 삽입하는 방법을 제안하였고, 동시에 냉매팩 삽입으로 인한 안전모의 무게 증가가 인체생리반응에 미치는 영향을 규명하고자 하였다. WBGT $33{\pm}1^{\circ}C$의 환경에서 인체착용평가 방법을 이용하여, 4가지 실험조건으로 안전모 착용시의 인체 생리반응을 조사하였고, 그 결과는 다음과 같다. 첫째, 안전모만 착용 시(OH)와 안전모 미착용시(NH)를 비교해 보면, 안전모 착용 시에 평균피부온, 직장온, 심박수, 발한량 등이 통계적으로 유의하게 높았고, 주관적인 감각에서도 더 덥고, 더 습하며, 불쾌하고 주관적으로도 힘들다고 느끼는 것으로 나타났다. 둘째, 냉매팩 삽입시의 경우(HA, HB), 냉매팩의 종류에 따라 여러 인체생리반응에 차이를 보였으나, 안전모만 착용한 경우(OH)와 비교 시 안전모내 기후, 발한량, 직장온 상승도, 열저장(heat storage) 등이 더 낮았다. 한서감과 쾌적감에서는 냉매팩 종류에 따라 다른 경향을 보였다. 본 결과를 통해 안전모 착용시의 생리적, 주관적 부담 정도를 객관적으로 파악할 수 있었으며, 안전모에 냉매팩을 삽입하는 방법을 서열 스트레스를 경감시키는 하나의 방법으로 제시할 수 있었다. 추후 연구에서는 냉매팩의 무게, 피복면적, 성분 등을 고려해야 할 것이며, 본 결과가 서열 환경에서 안전모를 착용하고 작업하는 여러 산업 근로자에게 도움이 되기를 기대한다.

대부분의 건설 재해는 공사장 안전수칙을 지키지 않거나 복장 및 보호장비 미착용, 안전 불감증 및 근로자의 건강 등의 인재로 분석된다. 이러한 건설 재해 예방을 위해서는 현장관리직이 근로자의 건강을 점검할 필요성이 있으나 매 시간 근로자의 상태를 확인하기는 어려운 실정이다. 따라서, 본 논문에서는 단순한 보호구 기능에서 벗어나 근로자의 산소포화도와 맥박 수를 체크하여 자동으로 건강 상태를 파악할 수 있는 디지털 안전모의 설계를 제안하였다.

Recently the use of personal mobility devices is rapidly increasing, and the businesses related to personal mobility devices are quickly growing as well. Although the use of personal mobility devices provides convenience for short distance movements, many problems occur due to the lack of safety devices and the absence of associated road traffic laws. The number of accidents caused by using personal mobility devices continues increasing every year, and the injuries or deaths are seriously happening with those accidents. When using personal mobility devices, there are basic safety precautions such as wearing a helmet, prohibiting boarding with more than two people, prohibiting boarding with more than 100kg, prohibiting using after drinking alcohol, and so on. However, it is exposed to traffic accidents because there is no way to check before using the system. Therefore, to ensure the user's safety in using the electric kickboard among personal mobility devices, this paper proposes a system that can check the user's safety state before using the electric kickboard. It is possible to safely use personal mobility devices and prevent accidents by proposing a system structure of the electric kickboard that can be used after checking for the use of more than two people, overweight, wearing a helmet, and drinking alcohol.

Safety management is the most important factor in the construction industry. If the construction company don't control the risk, it causes the accident which give the company fatal loss. According to the Korea industrial safety analysis reports, the 25.72% of the disasters are from the construction industry, and the 13.6% construction disasters are caused by not properly using the safety gears. Therefore, this study is to investigate the Wearing Safety Gear by Occupational Classification and the Satisfaction in the Construction Field. The results are ; Carpenters are dissatisfied with the safety shoes and belt, re-bar workers are dissatisfied with the safety helmet and shoes, Concrete workers are dissatisfied with the safety helmet and goggles.

At the present time, the number of accidents has enlarged speedily and in country like India per day there are about 204 accidents occurred. Accidents of two-wheeler compose a foremost segment of every accident and it can be true for the reason that two-wheelers like bikes not able to produce as many as security measurements normally incorporated in cars, truks and bus etc. General main rootcost of the two-wheeler accidents happen only when people community not remember to wearing a device helmet and during the driving time feels like sleep condition, alcohol disbursement, many of the drivers doesn't know heavy vehicles like Loory and buses approaching into very closer to their two wheelers, contravention of two wheelers in traffic rules and regulations. Let's overcome the above situations; our important objective is to develop an intelligent system device that can successfully facilitate in avoidance of every kind of problems. Suppose any of the above stated situations occurs, at that moment how system device identify and represents the commanders and community, and finally the stated situation be able to taken care of straight away without any further delay. A smart intelligent helmet system is a defending head covering used by rider for making bike riding safer than earlier. This is finished by incorporating sophisticated features like detecting the usage of helmet by the rider, connected Bluetooth module in helmet. In order to maintain the temperature inside the helmet device we need to include CPU fan module inside the device. RF based helmet prevents road accidents and identify whether people community is not using a component helmet or used. Main responsibility of the system is to detect accidents by vibration sensors, accelerometers and also with the help of modules global positioning system and global system for mobile commnicaiton module. A wireless communication device used to discover the accident area site location and likewise notifying the two-wheeler drived people's relatives and short message text information passed to the positioned hospitals.

Recently, due to the effect of global warming, the high temperature phenomenon continues, and the time for workers exposed to high temperature, cold and infrared is increasing and then safety is threatened. Due to the nature of on-site work, the work is being carried out in an unreasonable manner due to the process, which is exposed to disasters due to high temperature and cold. Even though the injured skin may be damaged, the worker may not be aware of it and may be injured. By understanding the working environment of the worker and calculating the risk index and expressing it on the helmet, the surrounding colleagues inform the worker of the risk and take appropriate measures so that the accident can be prevented in advance. This study was conducted to investigate the effect of exposure duration on the workers' by measuring the exposure time, the risk index is displayed in the form of a traffic light to the helm, informing neighboring workers and managers, and transmitting to the workers by voice.
