The incidence of in-line skating injuries has increased with the rapid growth in the sport's popularity. The purpose of this article is to describing the type of the inline skating and document basic skills, protective equipment use, identify contributing or precipitating factors associated with injuries. Loss of control and inexperience were factors contributing to the injuries. Also protective equipment among skaters was underused. In conclusion, the safety education program for inline skating, optimal design and efficacy of protective equipment should identify with further study.

The aim of study intends to investigate effect of weight of fire fighting protective equipment for physical activity ability and to provide the base data for the safety of firefighter. The results of the study are as follows. The maximum all-out time is short about 18.8% in weight-jacket case which weight is same with fire-protective equipment than case of gym suit. The maximum oxygen consumption increased 17.6% in gym suit case than case of weight-jacket. The maximum heart rate is high 5.4% in gym suit case than case of weight-jacket.

Korea's police force has successfully performed its difficult mission of maintaining public order while overcoming difficulties at home and abroad during the past half century. However, the environment in which the forces of law a nd order operate has exponentially increased the demand for, and difficulties faced by, the agents of law enforcement in recent years because of the country's rapid globalization, as well as the move to democracy and localization, and the extensive developments in industrialization and information technology diffusion. This study also intends to investigate the appropriate limits of law enforcement and the use of force by policemen, and the general public's perception of the police as they fulfill their duty of protecting citizens' rights.

This research aims at investigating the factors that affects the wearing of the nuclear protection equipment by radiology students. We measured the factors related to the wearing of the nuclear protection equipment based on the theory of planned behavior (TPB). We collected 192 survey records from 230 radiology students in Kwang-ju and Chun-nam providence who finished the clinical training. Based on Logistic Regression analysis, we found that the wearing of the nuclear protection equipment is statistically more probable as the level of study is lower, the scale of practicing hospital is smaller, the attitude rating is lower, and the rating of perceived behavioral control is higher. We argue that the development of educational program considering factors like the perceived behavioral control is required to enhance the degree of wearing the nuclear protection equipment in the clinical training of college students.

To minimize the death and injury by a collision, the installation of an air bag is recommended as a mandatory practice together with the wearing of the seat belt. By using simulated collision experiments, this research focused on the effect of an air bag and seat belt on the driver safety. The vehicle deceleration characteristics were obtained from impact experiment. LSDYNA, a software program for vehicle collision analysis, and MADYMO. a software program for driver motion after collision, were used for simulated experiment. Four cases such as air bag installed and seat belt wearing (case A), air bag installed but seat belt not wearing (case B), air bag not installed but seat belt wearing (case C), air bag not installed and seat belt not wearing (case D) were analyzed. The impact of acceleration on the injury of driver's head was analyzed by Head Injury Criterion (HIC) as well. It was found that having air bag and wearing seat belt effectively reduced driver's head injury about 52.9% to 70.5% compared with the case of having neither air bag nor wearing seat belt.

This study aims at illuminating the state of car seat use and relevant factors and providing basic data to enhance the consciousness of children's safety with the target group of parents who have 5~6 year old kindergarten pupils in a specific city. The target group to study is 189 fathers and mothers who have 5~6 year old kindergarten pupils in five different kindergartens in a city. Structured questionnaires are used and the major research results are the followings: The use rate of children's car seat is the higher in the lower age (p=0.128), boys (p=0.474), mothers below the age of 30s(p=0.294). The use of children's car seat is significant in the mothers who graduated high school or lower (p=0.009), and fathers(p=0.010) who are working in offices or service occupations. The study on the recognition rate of the free lease of children's car seat conducted by Korea Children Safety Foundation shows parents who earned 3 million won or lower per month(p=0.009) significantly, and the major significant factors affecting the use of children's car seat are existence or nonexistence of car seat education and kinds of parent's occupation.

The design of an occupant protection equipment has been considered as the important process in developing a new car since the crash performance plays an important role on the market. The cost is increased when an unexpected real test is carried out in the proto-design stage. Thus, the exact prediction of a crash performance can reduce the number of full-car test. In this research, the robust design of an airbag system considering the frontal crash is suggested to predict the more reliable responses. On the contrary, most existing researches do not consider the uncertainties. The uncertainties treated in this research are the tolerances of the vent hole, the time to fire and the length of a strap in airbag and the tolerance of the load limiter load in seat belt. The Taguchi method is utilized to determine the robust optimum of each parameter

Using the orthogonal arrays and the occupant analysis software based on the multi-body dynamics , two interactive design algorithms are proposed to improve the initial design of the occupant protection systems. Algorithm 1 sequentially moves the narrow design space within the upper and the lower design limit. Algorithm 2 sequentially reduces the relatively wide design space. Each design algorithm is composed of two levels . The first level is to improve the characteristics of the crash performance considering the noise factors. In order to obtain the robust design, the second level reduces the variations the noise factors. In order to obtain the robust design, the second level reduces the variations due to the tolerance of the design variable. To utilize the algorithm 1, HIC(Head Injury Criterion) , 3 msec criterion value of the chest acceleration and the femur load decreased by 27.4%, 10.4% and 55.8%, respectively. To utilizer the algorithm 2 , the results decreased by 38.0%, 10.5% and 3.0% , respectively.
