Objective: We developed an ergonomic pruning shears that allows the user to freely adjust the width of the grip and conducted this study to examine the effects of the pruning shears on grip strength and the fatigue of the fingers. Method: The maximum grip strength was first measured with an digital dynamometer, and the maximum grip strength was measured again after the subjects repeated scissoring 100 times using general pruning shears or ergonomic pruning shears. Borg s CR-10 scale was used to measure subjective fatigue after using the two pruning shears. Results: When the grip strength values after using the two pruning shears were compared with each other the mean grip strength after using ergonomic pruning shears was 27.69 kg, which was higher than that after using general pruning shears, 25.73 kg (p<.05). The subjective fatigue when the two pruning shears were used was shown to be 3.6 points for general pruning shears and 1.73 points for ergonomic pruning shears (p<.05). Conclusion: After repeating scissoring 100 times, the fatigue of the fingers was lower when ergonomic pruning shears were used than when general pruning shears were used and grip strength was higher when ergonomic pruning shears were used than when general pruning shears were used.

This study examines the effects of ankle manual therapy(MT), gastrocnemius Evjenth-Hamburg stretching(ST), and manual therapy & Evjenth-Hamburg stretching(MST) on middle aged female balance, ankle range of motion, and center of pressure. A total of 68 female were divided into three groups of 21, 23, and 24 and then were given one application of each of MT, ST, and MST at three hospitals in Seoul. In order to assess their balance before and after the application, the timed up and go(TUG) test and functional reach test(FRT) were conducted, and center of pressure(COP) migration was measured. A paired t-test was carried out for a before-after comparison of the TUG, FRT, and COP within each group. One-way ANOVA was conducted to compare the amount of change between the groups. Within each group, all of the three interventions showed significant differences in ankle range of motion and TUG within each group(p<.05), while the FRT and COP showed significant differences after the application of ST and MST(p<.05). According to comparison between the groups, ankle range of motion, TUG, and FRT showed significant differences(p<.05), and all of the test results improved in the MST group compared to the other groups. Applying manual therapy and stretching together is a more effective intervention than applying manual therapy or stretching alone. 본 연구는 중고령 여성들을 대상으로 발과 발목관절에 대한 치료적 중재가 여성노인의 균형 및 족저압 이동 분포에 미치는 영향에 대하여 알아보기 위하여 시행하였다. 연구방법은 68명의 중고령 여성을 대상으로 도수치료 적용군 21명, 스트레칭 적용군 23명, 도수치료와 스트레칭 적용군 24명으로 집단을 나누어 시행하였다. 결과적으로 발과 발목 관절에 대한 치료적 중재에서 도수치료 및 스트레칭 적용군이 발목관절가동범위, 균형, 족저압분포의 이동 면적에서 가장 크게 향상되었음을 보여주었다. 본 연구를 통하여 중고령 여성노인들에게 낙상사고를 예방하기 위하여 발목에 대한 도수치료와 스트레칭이 적절한 치료적 중재라고 사료되며 향후 노인분들의 운동시 참고자료로서 제시하고자 한다.

Recently more people are turning to power walking (fitness walking) to improve and maintain their health. But, there was no clinical data of difference between fitness walking and running in exercise intensity. The purpose of this study was to make a comparison of exercise intensity between power walking and running. Twenty one healthy male subjects completed steady state exercise at selected speed of 6∼8 km/hr by power walking and running. The parameters of exercise intensity including heart rate, oxygen consumption and Borg scale of perceived exertion were measured for last 2 minutes of each exercise treadmill test. The results showed that power walking had similar intensity to running in all of the parameters. The intensity of power walking is about 90∼96% of that of running. This study suggests that power walking might be a good alternative aerobic exercise to running.

The Taekwondo being a martial sports, there are higher chances for the injury to occur than the non martial sports. Therefore, this study analyze th efrequency, the area, the type, and the condition of the injury which are prone to occur in the Taekwondo matches; it is to help the Taekwondo players in prevention of the injury and in treatment. The subjets of thsi study were the 48 players (male 24, female 24) who participated in the final selection contest of the national team player on March 9 to 12, 1993. The data of the injury were obtained from the medical recoder staff and were analyzed to the frequency of the injury per match, the vulnerable area of the injury, the type of injury, and the condition of the injury with a gender difference. There were 24 matches for the male and 24 matches for the female, total 48 matches. Therefore, the total participation number of the players are the double of the match number. 1. The frequency of the injury per match was 18.3%(11/60) for male and 23.1%(12/52) for women. 2. The areas of the injury were ankle 36.4%(4), foot 18.2%(2), knee 18.2%(2). lower leg 18.2%, wrist 9.1%(1), in male: foot 33.4%(4), ankle 16.7%(2), knee 16.7%(2), lower back 16.7%(2), lower leg 8.3%(1), face 8.3%(1) in female. 3. The types of the injury were contusion 45.5%(5), sprain 27.3%(3), abrasion 9.1%(1), laceration 9.1%(1), tendon rupture 9.1%(1) in male: contusion 33.3% (4), sprain 33.3%(4), abrasion 16.7%(2), subcutaneous hemorrhage 8.3%(1), dislocation 8.3%(1) in female. 4. The condition of the injury were the unblocked attack 36.4%(4), attacking kick 27.3%(3), blocking a kick 18.2%, attacking punch 9.1%, impact with surface 9.1%(1) in male: attacking kick 33.3%(4), unblocked attack 25%(3), blocking a kick 25%(3), attacking puch 8.3%(1), impact with surface 8.3%(1) in female. This study shows that the injury from the Taekwondo matches occurred most in the lower extremity joints and the foot, and shows that the most of the injury types were contusion and sprain. Therefore, it is believed to be helpful to wear the proper fitting ankle or the knee protector and using other protective equipment to prevent the sports injury in the Taekwondo matches.
