  • 본 연구는 12주간 비만 중년여성의 복싱에어로빅 운동프로그램 참여가 신체조성, 혈액성분 및 혈관탄성에 미치는 영향을 규명하기 위해 수행되었다. 본 연구의 대상자는 40세 이상의 중년여성으로 체지방율 30%이상 병역 상심혈관질환 및 대사성 질환이 없는 신체적으로 건강한 사람을 대상으로 복싱에어로빅 운동집단 8명과 통제집단 8명으로 무선배정(random assignment)으로 나누었으며, 복싱에어로빅 운동강도는 초기 1-4주는 HRmax 50%, 5-8주는 HRmax 60%, 9-12주는 HRmax 70%로 총 60분간 실시한 후 다음과 같은 결론을 얻었다. 첫째, 복싱에어로빅 운동프로그램 참여 결과 운동집단에서 체중, 체지방률과 근육량은 측정시기, 그룹과 측정시기의 상호작용이 유의한 차이를 나타냈으며(p<.001), 그룹별 측정시기 간의 대응표본 t-test 결과에서도 운동집단에서 유의한 수준의 감소 및 증가를 나타냈다(p<.001). 둘째, 복싱에어로빅 운동프로그램 참여 결과 운동집단에서 TC, TG, HDL-C, LDL-C 모두 그룹, 측정시기, 그룹과 측정시기의 상호작용효과도 유의한 차이를 나타냈으며(p<.01, p<.001), 그룹별 측정시 기간의 대응표본 t-test 결과 운동집단에서 유의한 감소와 증가를 나타냈다(p<.01). 셋째, 복싱에어로빅 운동프로그램 참여 결과 운동집단에서 오른손, 왼손, 오른발, 왼발의 혈관탄성은 그룹, 측정시기, 그룹과 측정시기의 상호작용 효과도 유의한 차이를 나타냈으며(p<.001), 그룹별 측정시기 간의 대응표본 t-test 결과 운동집단에서 유의한 증가를 나타냈다(p<.001). 이상의 결과를 종합해 볼 때, 12주간 복싱에어로빅 운동프로그램 참여는 신체조성 및 혈액성분을 개선시키고, 혈관순환 능력을 향상시켜 심혈관질환 등의 예방 및 개선 할 수 있을 것으로 사료된다.

  • Purpose: Restoration of ankle stability through the strengthening exercise of peroneus muscles is considered an important factor for achievement of successful outcomes, in the rehabilitation program following ankle ligament injuries. However, there were few definitive data on normal muscle strength, including eversion power by peroneus muscles. This study was conducted to evaluate the muscle strength of ankle joint measured using an isokinetic dynamometer in normal Koreans. Materials and Methods: Sixty adults (120 ankles) were recruited and divided into three groups (20 in their twenties, 20 in thirties, and 20 in forties). Each group consisted of 10 males and 10 females. The selection criteria were no history of ankle injury and no evidence of instability. The peak torque, total work, and deficit ratio were measured using the Biodex$^{TM}$ (Biodex Medical Systems). Differences in muscle strength by age, gender and dominant versus non-dominant side were analyzed. Results: The peak torque of dorsiflexion was average 31.5 Nm at $30^{\circ}/s$ of angular velocity and 18.8 Nm at $90^{\circ}/s$; average 69.3 Nm ($30^{\circ}/s$) and 42.4 Nm ($90^{\circ}/s$) on plantarflexion; average 19.6 Nm ($30^{\circ}/s$) and 10.8 Nm ($90^{\circ}/s$) on inversion; average 12.9 Nm ($30^{\circ}/s$) and 8.0 Nm ($90^{\circ}/s$) on eversion. The deficit ratio of strength in women was average 61.1% of men on dorsiflexion; average 66.2% on plantarflexion; average 48.5% on inversion; average 55.4% on eversion. The deficit ratio in non-dominant foot was average 88.6% of dominant foot on dorsiflexion; average 90.1% on plantarflexion; average 85.1% on inversion; average 85.6% on eversion. Conclusion: The muscle strength of the ankle joint showed a tendency to weaken with age. There were significant differences in muscle strength by gender and dominancy. Further studies for comparison of patients with ankle instability, a comparison between before and after surgery for instability, the correlation between clinical outcomes and the recovery in muscle strength will be needed.

  • To correctly plant the value of sex to the juvenile, we cannot overemphasize the importance of the sexual education in schools. Therefore, the study for teachers' consciousness and view of sex is also necessary, because they are subjects of education and role-models of sex of their students. Especially, if teachers are over fifty in age, it is more important, because it is obvious, as they are in positions of managers and directors of education, that their view of sexual value and consciousness are influencing the aim of education and the course of education. Hereby this study was conducted to check their sexual consciousness, attitude, and condition and to prepare for the basic data needed for the development of a sexual education program suitable to them. The methods of the survey of this study are applied by modifying or supplementing those of precedented studies. They are used after analyzing reliance of items according to Cronbach's $\alpha$ figure calculating law, and modifying or supplementing items lower in reliance. The questionnaire survey was conducted among 1,000 randomly selected from teachers working in middle and high schools in Korea from June 14th in 2004 to June 30th. The survey analyzed 632 questionnaires suitable to it. The outcomes of the survey of this study are like the following: First, the objects of the survey consist of 64.6% men and 35.4% women. Among them, 41.1% are under fifty and the rest are over fifty. As for the periods of marriage, 15.5% are unmarried, 16.3% are under ten years, 18.0% are between ten and twenty, and 50.2% are over twenty. Second, with reagard to sex, 25.6% admit the necessity of a heterosexual friend. 32.0% say that they are conservative to sex. 54.1% are taught sexual education. 67.1% attribute sexual education to nursing teachers. Third, among those who answer that they enoughly know the concept of sex, seenig by age, 25.0% are under fifty and 58.1% are over fifty. Seening by the periods of marriage, 9.2% are unmarried, 28.2% are under ten, 49.1% are between ten and twenty, and 59.0% are over twenty. Among those who answer that they enoughly know the concepts of sexual harassment and sexual violence, seenig by age, in the turns by above-mentioned order, each 47.7% and 76.3%. Seening by the periods of marriage, each 9.2%, 28.2%, 49.1%, and 59.0%. Fourth, among those who answer that "teachers also need sexual education and sexual counsel," by age, each92.7% and 91.4%. By the periods of marriage, each 89.8%, 95.2%, 89.4%, and 92.4%. As a matter of course, we can infer the necessity of the sexual education and sexual counsel for teachers. Fifth, among those who answer that they are satisfied with their sexuality, by age, each 41.1% and 61.3%. By the period of marriage, each 4.1%, 63.1%, 64.1%, and 61.5%. As for the sexual desire like spiritual intercourse, physical intercourse containing sexuality, by age, each 71.9% and 93.5%. By the periods of marriage, each 54.0%, 81.5%, 90.3%, and 93.0%. The survey shows that those over fifty and having long marriage are feeling the stronger desire towards sexuality. Through the outcomes of this survey, a few suggestions are possible: First, it is necessary to check of the teachers' view of sexual value and to study deep about the sexual tendency of them in twenties, thirties, and forties. It is to make them teach their students on the firm basis, and also to develop suitable sexual education and counsel program.
