The purpose of this study is to examine the career choice of students majoring in physical education at Korea and Japan universities after graduation. The subjects of this study were Korea physical education students in C University G Metropolitan City(n=80) and Japanese physical education students K University F City(n=107). The results of the questionnaire on career choice were as follows. The result of the recognition of employment activity, planning, job activity, and information in college are considered to be important by students of Korean physical education, and students of major in physical education in Japan consider it important for job anxiety, sense of purpose, prospect, and prudence appear. Results of consideration in Job-seeking activities, the students of the Korean Physical Education major showed the importance of the workplace, location, and distance. The students of the Japanese physical education major emphasized on the utilization of professionalism, working environment, level of salary, taste and interest, desired occupation, development experience, welfare and service level satisfaction. Based on the above results, it was found that the college students majoring in physical education who had to choose their career were aware of the importance and interest in matters to be considered in their employment and job search activities. The students who are employed in career decision tend to be higher in Japan than in Korea, and tend to be most successful before they graduate. At this point, I think that if we prepare active employment activities and various programs to enhance job satisfaction with active job search activities, we will be able to make a successful career choice according to our major.

In this study, we used the Elastic Band exercise as a method to prevent obesity and various diseases of middle-aged women who had little physical activity and compared the body composition, liver and blood glucose levels. The following conclusions were obtained. There was a decrease in body weight but no statistically significant difference. Body fat percentage was also decreased, showing statistically significant difference. There was a statistically significant difference the AST and the ALT. However, γ-GTP was significantly decreased but not statistically significant. The blood glucose level was in the normal range but decreased, indicating a statistically significant difference. From the above, it is suggested that Elastic Band exercise is recommended for middle-aged women because it has significant changes in body composition, liver and blood sugar. I would like to study the effect of the Elastic Band movement by studying and analyzing the movements using the elastic band.

This study was conducted to investigate the effects of trampoline exercise on blood oxidative stress and total antioxidant activity in middle-aged women. Middle-aged women consisted of 40 minutes a day, three times a week for a total of eight weeks, divided into exercise group and general control group. The following conclusions were drawn. First, it was found that there was an interaction effect only in measurement time * groups in blood oxidative stress of middle-aged women participating in trampoline exercise. Second, the total antioxidant power of middle-aged women who participated in the trampoline exercise also showed an interaction effect between the measurement time * groups. Taken together, the trampoline exercise is recommended as one of the exercise programs to help middle-aged women maintain their health by reducing the blood oxidative stress and increasing the total antioxidant power of middle-aged women. In order to get more exercise effect, extend the exercise period and increase the intensity, than I think it will be possible to have a healthy middle age by promoting health.

Recently, the GX program has been jumping for exercise to change diet or body type. The jumping exercise was divided into exercise group and control group for 40 minutes a day for a total of 8 weeks. The following conclusions were drawn based on the results of lifestyle-related risk factors and stress in middle-aged obese women. The body composition item showed a decrease in body weight and body fat percentage, indicating an interaction effect. The risk factors for lifestyle-related disease were also reduced in fasting glucose, TC, and TG, indicating an interaction effect. In addition, α-amylase, an external stress index, showed a decreased result, indicating an interaction effect. Taken together, it was concluded that jumping exercise improved the body shape of middle-aged obese women, suppressed and reduced the risk factors for lifestyle-related disease, and relieved stress. In order to maintain and improve the health of these exercises, a variety of subjects will be further diversified, and further studies will be conducted to verify the effectiveness of the jumping exercise if recruiting subjects with secondary disease rather than lifestyle-related disease risk factors.

탄력밴드운동이 여성노인의 보행기능과 근기능에 미치는 효과

서영환(Young Hwan Seo),나승희(Seung Hee Na) 한국발육발달학회 2013 한국발육발달학회지 Vol.21 No.2

본 연구의 결과분석은 기간에 따라 하였다. 자발적으로 참여한 65세 이상, 75세 미만의 여성 노인 중 약물을 복용하고 있는 자는 제외하고 규칙적으로 운동을 하지 않고 운동을 하는 데 지장이 없는 9명을 대상으로 밴드운동을 실시하여 보행기능과 근기능에 미치는 영향을 알아보는 것이다. 1. 보행기능의 변화 노인들의 전반적인 근력 저하는 운동의 저하를 일으키며, 근력저하로 인한 신체활동의 감소로 이어진다(권오윤, 1997). 아울러 연령이 증가함에 따라 노화와 관련된 생리적 변화에 따라 고유수용성 감각이 감소하고, 정위반사(righting reflex)가 느려지며, 자세유지에 중요한 근력이 감소하고, 자세의 동요, 그 로인해 균형유지가 어려워진다(배철영과 이영진, 1996). 따라서 균형을 유지하는 능력은 인간이 일상생활을 유지하는 가장 기본적인 필수 요소이다. 여성노인이 낙상을 방지하고 건강한 생활을 영위하기 위해서는 보행능력은 무엇보다 중요한 요소이다. 균형능력은 노화로 인한 신체적 능력 저하로 정적평형능력이 70세 후반까지는 잘 유지되나 정적평행능력은 65세 이후 급속도로 감소한다(Kang et al., 1999). 신승민 등(2006)은 직선보행테스트의 결과를 볼 때 하지의 근기능 특히 대퇴사두근의 근지구력 향상과 협응력의 증진이 있음을 보고하였다. 아울러 보행속도, 분속수 및 보장에서 증가하였으나 유의한 차이는 나타나지 않았다고 하였다. 본 연구에서도 보행속도는 유의한 차이가 나타나지 않았으며, 분속수 및 분장에서 유의한 차이를 나타냈다. 또한 정성원, 최대원(2008)의 연구를 보면 보행능력은 근력 및 근지구력 등 신체 각 부위의 협응력이 요구되며, 보장 및 분속수, 보행속도를 증가시킨다고 보고하고 있다. Mill(1994)도 규칙적인 운동을 통해 노인들의 신체활동을 증가시키며, 보행속도를 증가시킨다고 하였다. 최상웅(2004)의 연구에서도 보폭의 증가를 보고하고, 전미양(2001)은 여성의 노인의 보행 및 균형, 근력에 미치는 효과에서 등척성 운동을 통해 대퇴 사두근과 하퇴 삼두근의 근력을 증가시켜 보폭의 길이가 향상되었다고 보고하였다. 이는 밴드운동을 통해 하지근력의 증가로 보행능력이 긍정적으로 향상되었음을 나타내는 결과라 사료된다. 2. 근육기능의 변화 노인의 건강을 위협하는 신체기능은 일상생활을 하는데 적지 않은 문제로 대두되고 있다. 그 기능 중에 근력, 유연성, 평형성 및 민첩성 등이 저하되는 문제로 볼 수 있다(Jeeup et al., 2003). 또한 Buchner and Lateur(1991)은 노년기 신체기능과 관련된 체력요소 중 근력은 기본적인 건강체력 요소이며 독립적인 삶을 영위하는데 필연적으로 작용하는 것이라 했다. 김택훈, 오동식(2000)은 8주 간의 운동결과 좌우의 신전근의 근지구력이 향상되었으며, 이는 지근섬유의 산화적 능력의 발달로 세포 내에 있는 미토콘트리아의 기능이 향상된 결과라고 하였다(Mayer, 1995). 본 연구의 결과 밴드운동이 근지구력이 유의하게 증가하였다. 이러한 결과는 정덕조, 주기찬(2003), Mikesky 등(1994)의 고령 여성을 대상으로 탄력밴드를 이용한 저항성 운동으로 증가 하였다는 보고와 진영수 등(1999)의 연구 보고와 일치하고 있다. 이는 저항성 운동이 일상생활의 신체기능증진에 기여할 것으로 본다. 신승민 등(2006)의 연구에서도 하지 근지구력의 향상은 대퇴 사두근의 근지구력향상 증진이 기여함을 보고, 조상근 등(2006)도 노인 여성에 있어 근력 운동의 중요성을 강조하고 있다. 또한 Nitz and Choy(2004)은 신체 안정성과 균형감각의 저하는 근력 약화를 지적하면서 이를 높이기 위해 근력 강화를 강조하고 있다. 김경룡, 방현석(2008)은 근력 및 유지를 위하여 슬관절의 신근력을 관장하는 대퇴직근, 내측광근, 외측 광근, 굴근력은 대퇴이두근, 반막양근, 반건양근, 박근, 봉공근의 근력가 및 수축력이 증가됨에 따라 나타난 현상이라고 하였다. 따라서 밴드운동을 통한 하지근력저항운동은 근력의 향상과 근섬유 크기의 변화를 가져오고, 노인들의 근력향상과 단계적인 저항운동이 효율적인 프로그램이라고 사료된다. This study conducted a band exercise program with elderly women (65∼75 ages) residing in D-gu, G Metropolitan City and voluntarily participating and the following results were obtained. First, as regards gait functions, although gait velocity was increased 6 and 12 weeks after exercise, no statistically significant difference was found. Cadence and step length was increased 6 and 12 weeks after exercise and statistically significant difference was found (p<.05). Second, as regards muscular functions, leg endurance was increased 6 and 12 weeks after exercise and there was statistically significant difference (p<.05). Although hand grip strength was increased 6 and 12 weeks after exercise, there was no statistically significant difference. Based on the findings, the exercise program using a band may effectively improve balance, coordination, leg endurance, and gait function in the elderly. It is expected that this exercise will be widely used to improve the elderly`s health through stepwise prescription in consideration of individual characteristics, environment, and conditions.

Most research on feedback has focused on its informational role. In contrast, motor learning researchers have somewhat neglected the motivational aspects of feedback, perhaps because motivation is often assumed to exert only temporary effects on performance or to have, at best, indirect effects on learning through increased practice. But more recently, studies following up on findings indicating that learners preferred to receive feedback after good trials have shown that providing feedback after relatively successful trials can enhance motor learning relative to feedback after less successful trials. This study examined motivational effects of feedback on motor learning. Specifically, we investigated the influence of social-comparative feedback on the motor learning of a badminton short serve task. Twenty-eight university students with mean age of 19 years took part in this experiment. Participants were randomly assigned to the positive feedback and control groups, with an equal number of females in each group. The practice data were analyzed in 2(groups)×6(blocks of 10 trials) analyses of variance (ANOVAs) with repeated measures on the last factor. The retention and transfer data were analyzed in seperate one-way ANOVAs. Bothe groups reduced their absolute and variable errors across the practice phase. The main effect of block was significant p<.001. And on the transfer test, requiring novel absolute short serve, the social-comparative group had smaller errors than the control group(p<.05). The findings of the present study demonstrated evidence that motivational factors have transient effects on motor performance and affect motor learning.

The purpose of this study is to examine the perception of sports international exchanges among college students in Korea and Japan and to compare their perceptions of sports exchanges between the two countries. The subjects were physical education students(n=108) who attended C university in G city, Korea and students(n=100) attending K - area K university in Japan. In order to see the differences in the perception of sports exchanges between the two countries, the independent sample t test method was conducted. Based on the results, the following conclusions were obtained. In terms of the effect of participating in international exchange, Japanese students showed the importance in skill improvement, motivation, joy, confidence, ability improvement, interest, and interpersonal factors and Korean students showed importance in international sense, knowledge information and friendliness factor. As a result of the need for international exchange, Japanese physical education students showed a more significant difference in perception, language learning, relationship conscious effort, energy passion, and readiness. As a result of the abovementioned results, we conducted a survey on the sports interaction among students from Korea and Japan. As a result, it was found that Japanese students were more likely to participate in international exchanges They are aware of their interest and importance. The results of this study show that there is no big gap between the two countries. However, as suggested by the general characteristics, the recognition of the necessity of foreign travel experience and the hoped effect are the result of the basic and direct differences of experiences and cognitions about sports exchanges among students of Japanese physical education major compared with those of Korean physical education major. Students who major in physical education will be able to demonstrate their ability to develop sports in their respective countries as sports professionals who are awake to internationalization if they are more aware of sports exchanges and approach with more positive thoughts.

서영환 ( Young Hwan Seo ),이수연 ( Su Yeon Rhie ),박범준 ( Bum Joon Park ),김형준 ( Hyung Joon Kim ),김재규 ( Jae Gyu Kim ) 대한내과학회 2008 대한내과학회지 Vol.74 No.1

목적: 국내에서 Helicobacter pylori를 제균하기 위해 사용되는 PPI 표준 삼제요법과 bismuth 포함 사제 요법은 적지 않은 제균 실패율은 보이고 있다. 이번 연구의 목적은 일차제균 치료에 실패한 환자에서 이차 치료로 bismuth 포함 사제요법과 삼차 치료로 rifabutin 포함 삼제요법의 H. pylori 제균율을 분석하고, 구제요법으로서의 역할에 대해 알아보고자 하였다. 방법: 2004년 7월부터 2006년 10월까지 중앙대학교 필동병원과 용산 병원을 내원하여 상부위장관 내시경 검사에서 H. pylori 감염 진단을 받고 PPI 삼제요법 치료에 실패한 52명의 환자를 대상으로 이차 bismuth 삼제요법을 시행하였다. 또한 이차 제균에 실패한 3명의 환자를 대상으로 rifabutin 포함 삼제요법으로 삼차 구제요법을 시행하였다. 또한 연령, 성별, 질환, 음주, 흡연, 그리고 NSAIDs 복용력에 따른 제균율을 분석하였다. 결과: Bismuth 포함 사제요법의 제균율은 84.6%였으며, rifabutin 포함 삼제요법의 제균율은 100%였다. 연령, 성별. 질환, 음주, 흡연, 그리고 NSAIDs 복용력에 따른 의미있는 통계학적 유의성은 보이지 않았다. 결론: Bismuth 포함 사제요법은 PPI 포함 일차 삼제요법 실패 후 이차 치료로 여전히 효과적이며, rifabutin 포함 삼제요법도 국내에서 이차 치료 실패 시 삼차 구제요법으로 사용되어질 수 있을 것으로 생각한다. Background/Aims: Proton pump inhibitor (PPI)-based standard triple therapy for Helicobacter pylori infection is widely used, but it has a considerable failure rate. The aim of this study was to evaluate the efficacy and tolerability of rescue therapies with a quadruple regimen and a rifabutin-based regimen for patients who experienced failure with PPI-based standard triple therapy. Methods: From July 2004 through October 2006, 52 patients for whom first-line triple therapy (PPI, amoxicillin and clarithromycin) had failed were included in this study. They were treated with a quadruple regimen for 7 days (PPI, bismuth, tetracycline and metronidazole) as a second-line therapy. For third?line therapy, a rifabutin-based regimen (PPI, rifabutin and amoxicillin) was prescribed for 14 days. The H. pylori status was determined before and at least 4 weeks after therapy by the 13C urea breath test or by endoscopy with antral and corpus biopsies for a rapid urease test, histological examination and culture. Results: The mean age was 52.6 years. Thirteen patients (25%) of the 52 patients were dropped. The eradication rate of the quadruple therapy was 84.6% (33/39). Three patients of the 6 failures with quadruple therapy were then treated with the rifabutin-based regimen. The eradication rate of the rifabutin-based therapy was 100% (3/3). Adverse effects (10.2%) were reported in 4 patients who were treated with quadruple regimen. Conclusions: The quadruple regimen is still an effective second-line therapy for Korean patients who experience failure with PPI-based standard triple therapy. The rifabutin-based regimen could be used as a third-line rescue therapy in Korea. (Korean J Med 74:23-29, 2008)

서영환(Young Hwan Seo),손연희(Youn Hee Son),위승두(Seung Doo Wee) 한국발육발달학회 2011 한국발육발달학회지 Vol.19 No.2

The purpose of this study was to investigate effects of walking exercise on body composition, insulin resistance, circulating concentration of diponectin, ghrelin and resistin in obese male university students. Subjects were divided into control group (n = 14) and walking exercise group (n = 13). Walking exercise was performed 4 times a week at the intensity of 65-75% HRmax (1-4 weeks: 65% HRmax, 5-8 weeks: 70% HRmax, 8-12 weeks:75% HRmax). And the change of body composition, blood glucose, insulin, HOMA-IR, adiponectin, ghrelin and resistin has been measured before and after 12 weeks of exercise. Statistical technique for data analysis was two-way ANOVA to determine the difference between before and after 12 weeks of walking exercise. As a result, body weight, BMI, and VO_2max were significantly improved during post-exercise. The change of adiponectin, ghrelin and resistin in experimental group was significantly changed after 12-week walking exercise. The present study provides the possibility that walking exercise may be a critical mediator to improve insulin resistance, concentrations of adiponectin, ghrelin and resistin in obese male university students.
