The purpose of this study was to investigate the differences in upper and lower strengths and symmetry between upper body injury group, lower body injury group and non-injury group of bowling athletes. The subjects were the upper body injury group (UG), n = 16, the low body injury group (LG), n = 8, the non injury group, [NG], n = 15). The isometric strength of the bowler was measured using Manual Muscle Tester 01165 (Lafayette Instrument Company, USA) and the symmetry index (SI) was calculated. The results were as follow. The symmetry index of hip extension strength and hip external rotation strength was statistically larger in NG than LG (p <.05). The above results suggest that lower body strength and bilateral symmetry was closely related to injuries of the lower body. In order to prevent injury of the bowler, strengthening of lower body strength and symmetrical training are needed.

연구목적: 본 연구는 고교운동선수들의 스포츠상해(부상)현황 파악을 통한 사고 및 손상예방을 목적으로 개발된 손상감시프로그램을 설명하고, 1년간 수집된 자료를 보고하기 위하여 수행되었다. 연구방법: 본 연구는 미국 플로리다주 내의 10개 고등학교에 재학 중인 학생 운동선수들의 스포츠상해(부상)에 대한 세부내용(사고경위, 상해부위, 사고 당시 환경적 요소 등)을 수집하여 이루어졌다. 학생 운동선수들에게 발생한 스포츠상해 조사 및 보고는 2007년에서 2008년에 걸친 학기동안 각 학교에 배치된 운동트레이너(Certified Athletic Trainer)에 의해 이루어졌다. 연구결과: 조사기간 동안 10개 조사대상 고등학교에서 614건의 스포츠상해가 발생하였고, 연습 중 사고노출 비율(1,000회의 연습 중 1명의 선수가 상해를 입는 경우를 기준으로 함)에 있어서는 풋볼(Football)이 2.73을 기록해 가장 높은 상해율을 보였으며 여자축구(2.03)와 남자농구(1.67)가 그 뒤를 이었다. 실전경기 중 사고노출 비율(1,000회의 실전경기당 1명의 선수가 상해를 입는 경우를 기준으로 함)의 경우, 풋볼(Football)이 14.4, 여자농구가 9.96, 레슬링이 7.1을 기록하였다. 운동상해로 인한 증상은 염좌/삠(관절손상)이 가장 많았고, 가장 많이 다치는 신체부위는 발목, 무릎, 머리인 것으로 나타났다.

생체역학(biomechanics)은 생물(bio)과 역학(mechanics)의 합성어로서 글자 그대로 생명체에 관 련된 역학을 다루는 학문이다. 생체역학의 역사는 레오나르드 다빈치가 혈액순환에 대하여 관 심있게 관찰한 것이 효시가 되겠지만 본격적인 생체역학은 Alfonso Borelli가 1680년에 "동물의 동작에 관하여"(De motu animalium)라는 책을 출판한 것이다. 생체역학은 공학의 발달 및 인 류의 건강복지 향상에 대한 관심의 증가로 장족의 발전을 하고 있으며 정형외과학, 재활의학, 체육학, 산업공학, 상해예방, 생리학, 외과학등 다방면에 응용되고 있다.에 응용되고 있다.

This study sought to compare beliefs regarding injury, accidents, and prevention behaviors between mothers and teachers in childcare centers. The subjects were 252 mothers whose children were aged between 1 and 4 years old and 264 teachers in childcare centers. The data were analyzed using t-tests, ANOVA, and partial correlation. Our results were as follows; 1) Mothers believed that by experiencing minor injuries young children would learn to recognize risk and develop their abilities to endure pain. Mothers engaged in prevention behaviors in accidents less when compared to teachers in childcare centers. 2) Mothers and teachers in childcare centers whose ages were below 30-years-old and whose education levels were below high school tended to believe young children would learn to recognize risk through accidents, and they engaged in prevention behaviors in accidents less. 3) There was a negative correlation between injury beliefs and prevention behaviors in accidents.

The purpose of this study is to provide basic data for injury prevention and performance improvement by developing a flywheel training program for handball players. The results of analyzing the effects of the 12-week complex flywheel training program on body composition, physical fitness factors, anaerobic power, and isokinetic muscle function are as follows. There was a significant difference between groups in push-ups. Body fat percentage and anaerobic power showed significant differences in the interaction by period. Long jump, slow jump, grip strength, back muscle strength, anaerobic average power, and isokinetic muscle function tests showed significant differences by period in the left and right flexors. Therefore, it is considered that 12-week flywheel training results can be used as the basic data for injury prevention and improvement of performance in handball players.

The purpose of this study was to investigate the effects of anterior cruciate ligament (ACL) injury prevention program on the ground reaction force during the rebound in female highschool basketball players. Sixteen highschool female basketball players (ages 16 to 18 years) were participated in this study. Eight of these players participated in a 8-week ACL injury prevention program. Before and After ACL injury prevention program, initial peak value(%BW), maximum peak value(%BW), impulse(%BW sec), and loading rate(N/sec) were measured in the players. The experiment group after ACL injury prevention program showed significant decreased initial peak value, impulse, and loading rate.

Automobiles have long been an essential part of daily life, but the social costs of car traffic accidents exceed 9% of the national budget of Korea. Hence, it is necessary to establish prevention and response system for car traffic accidents. In order to present a model that can classify and predict the degree of injury in car traffic accidents, we used big data analysis techniques of K-nearest neighbor, logistic regression analysis, naive bayes classifier, decision tree, and ensemble algorithm. The performances of the models were analyzed by using the data on the nationwide traffic accidents over the past three years. In particular, considering the difference in the number of data among the respective injury severity levels, we used down-sampling methods for the group with a large number of samples to enhance the accuracy of the classification of the models and then verified the statistical significance of the models using ANOVA.

Maritime pilots are always exposed to unpredictable risks present in the marine environment because they are boarding ships through pilot ladders or accommodation ladders at sea. Since the pilot plays an important role in securing the safety of a ship entering or departing from a port, an injury to the pilot substantially affects the overall safety of the ship. The purpose of this study is to analyze pilot injuries and predict accidents. For this purpose, pilot injury cases are analyzed and potential situations are identified through a survey. Pilot injuries are also predicted. The survey was analyzed using the IPA (Importance-Performance Analysis) methodology, and the binomial distribution and Poisson distribution were used to predict injury trends. As a result of the study, 316.8 nearmiss occurred per pilot injury, and if the current accident management system is maintained, the probability of pilot injury occurring within 3 months is 64.4%. Based on the research results, the need for a management system to prevent pilot injuries and reinforcement of maintenance and installation for pilot ladders was suggested.

암을 유발시키는 원인은 생물, 물리, 화학적 요인 등 여러 가지가 있으나 근자에 들어 산업후에 따르는 환경오염의 증가는 화학적 원인에 의한 발암가능성을 증대시키고 있다. 이러한 화학적 인자의 발암 기전 중 많은 부분이 유전자에 상해를 일으킴으로써 암을 발생시킨다고 알려져 있다. 그러므로 항암실험을 수행하였던 파푸아뉴기니아산 열대식물 13과 23종 부위별 36시료에 대하여 항변이원성 검색실험을 통하여 유전독성을 가진 화학적 요인에 의한 발암 가능성에 대한 예방 효과를 알아봄으로써 발암에 대한 예방약물 개발의 기초 자료를 제공하고자 본 실험을 수행하였다.
