Dynamic modeling and kinematic correction of wheeled mobile robots with 2 d.o.f. are presented in this paper. Relative/absolute wheel-weight is revealed by using the kinematic model of wheeled-mobile robots. Motion of wheel-mobile robots with unequal wheel-radius are used to induce the dynamic model. The dead-reckoning algorithm and model-reference adaptive control are introduced to compensate for error owing to modeling uncertainty. And simulation results prove that method proposed by this paper is efficient.

본 연구는 12주간의 라켓스포츠 프로그램이 정신지체아의 신체조성, 건강관련체력 및 혈중지질대사에 미치는 영향을 분석하였다. 연구대상은 K지역에 거주하고 있는 정신지체 2급 중학생으로서 신체적으로는 의학적 질환이 없는 운동군 8명을 대상자로서 선정하였다. 운동방법은 12주간 주3회 준비운동 10분, 본 운동 40분, 정리운동 10분으로 총 60분으로 구성하였으며, 훈련 프로그램은 연구자의 선수생활과 다양한 지도경험을 바탕으로 수정 · 보완 하였고, 더불어 배드민턴 전문가와 함께 프로그램(1~6주:기초기술, 7~12:응용기술)을 구성하였다. 또한 실험에 참여 하기 전 1주간의 운동적응 기간을 설정하고 진행하였으며, SPSS ver 18.0 통계프로그램을 사용하여 집단 내 사전 · 사후 paired t-test 로 분석한 결과 다음과 같은 결론을 얻었다. 12주간의 라켓스포츠 프로그램은 정신지체아의 제지방량, 근지구 력, 유연성 및 심폐지구력에서는 유의한 차이가 나타났으며, 반면 체지방률과 근력 및 혈중지질대사 모두에서는 통계적으로 유의한 차이가 나타나지 않았다.

본 연구는 라켓운동참여가 과체중 남자 중학생의 신체조성 및 렙틴에 미치는 영향에 대해 연구하였다. B지역 D학교 재학생으로서 과거·현재까지 특별한 병력이 없으며 현재 건강상태가 양호한 대상자로 구성하였고, 대상 자의 구체적인 선정기준은 BMI 지수 25(kg/㎡)이상인 대상자로 운동군 8명, 대조군 8명으로 총 16명으로 대 한비만학회(2009) 기준에 근거하여 구성하였다. 측정항목은 신체조성(체지방률, 제지방량), 렙틴을 분석하였으며, 신체조성은 측정 전 음식섭취를 통제한 후 30분 정도의 안정을 취한 후 금속류와 측정에 방해가 되는 부분을 제거 한 후 InBody 430(Biospace, Korea) 을 이용하여 측정하였고, 혈액분석은 사전/사후 동일한 방법으로 검사 전 12시간 이상 수분과 음식섭취를 통 제한 후, 안정상태에서 약 10 ml를 주정맥(cubital vein)에서 채혈하였다. 운동프로그램은 배드민턴 프로그램을 채택하여 실시하였으며, 참여대상자는 훈련이 실시되기 1주 전 가벼운 적응훈련 및 종목기술에 대한 이해와 안전문제에 대해서 교육을 실시하였고, 프로그램 구성은 배드민턴 관련 연구(안재욱, 2013; 한민재, 2013; 박시원, 2013; 서혜리, 2013)의 자료를 참고/수정하여 총 12주간의 프로그 램을 구성하였다. 운동빈도는 주 3회(1일 60분: 준비운동 10분, 본 운동 40분, 정리운동 10분)로 실시하였고, 훈련내용은 1~6주(기초기술), 7~12주(전문기술/응용기술)과 운동강도는 무선 심박수 측정기인(Polar RS 400sd, Co. Finland)를 이용하여 목표심박수 범위에서 운동이 될 수 있도록 Karvonen & Vuorima(1988)의 방 식에 의한 목표심박수 산출방법과 Borg(1998)의 주관적 운동강도(RPE)를 포함하여 실시하였다. 이를 근거로 점증적 과부하의 원리를 적용하여 1~6주는 40~50% HRR(RPE 12~13), 7~12주는 51~60% HRR(RPE 14~15)으로 실시하였다. 자료처리는 SPSS Ver. 20.0 통계package를 이용하여 모든 변인에 대한 평균(M)과 표준편차(SD)를 산출하였 고, 각 집단과 시기에 따른 상호작용효과와 집단 간, 시기 간의 차이검증은 이원반복측정분산분석법(Two-way repeated measures ANOVA) 으로 분석하였다. 모든 통계치에 대한 유의수준(α)은 .05로 설정하였다. 연구결과는 체지방률은 각 집단과 시기 간의 상호작용효과검정결과 시기(p<.01), 집단(p<.05), 집단 및 시기 (p<.001)에서 유의한 차이가 나타났다. 제지방량은 각 집단과 시기 간의 상호작용효과검정결과 시기(p<.01), 집단(p<.05)에서 유의한 차이가 나타났으며, 집단 및 시기에서는 차이가 나타나지 않았다. 렙틴은 각 집단과 시기 간의 상호작용효과검정결과 시기(p<.05), 집단(p<.05), 집단 및 시기(p<.01)에서 유의한 차이가 나타났 다. 본 연구결과를 바탕으로 라켓운동의 특성이 관절계통의 움직임과 기술체력 등이 대상자의 근육량 증가에 도움이 있었으며, 장기적이고 지속적인 신체활동이 근육량과 동시에 에너지 소비와 지방조직의 지질분해를 증 가시키는데 효과가 있다고 볼 수 있다. 렙틴의 경우, 감소하는 결과는 운동 그 자체가 렙틴 농도 분비 비율을 억제하는 간접적 작용으로 볼 수 가 있었으며, 이처럼 청소년기의 과체중 및 비만의 경우 누구나 쉽게 접 할 수 있는 활동적 프로그램으로 대상자의 특징, 운동경력, 운동형태, 운동강도 및 운동빈도가 중요하다고 사료된다.

본 연구는 배드민턴 연합회에 등록된 B급 수준의 20대 남성 배드민턴 동호인 12명을 대상으로 실시하였으며, 배드민턴 프로그램은 총 4주간 준비훈련기(1주), 시합훈련기(2주), 회복훈련기(1주)으로 구성 하였으며, 운동빈도에서 일반훈련군은 주 5회(월∼금), 과다훈련군은 주 3회(월/수/금)으로 실시하였다. 본 실험결과에 따른 심폐기능 최대산소섭취량은 집단, 시기, 집단/시기간 상호작용의 유의한 차이가 나타났다. 혈중 피로물질인 젖산의 결과는 각 집단 내에서 유의한 차이가 있었고, 집단, 시기, 집단/시기간 상호작용결과 시기, 집단/시기에서 유의한 차이가 나타났다. 이상의 결과 지속적 과도한 훈련은 심폐기능, 피로물질, 체력기능의 유지 및 향상에 부정적인 영향을 미치는 것으로 판단되며, 동호인의 경우 선수와 다르게 시합이 다가올수록 연습량이 증가하는 경향을 보이고 있어 대상자 수준의 적절한 연습방법이 제공되어야 할 것으로 사료된다. The purpose of this study was to analyze the effects of badminton training on cardiorespiratory function and blood lactate variables in men’s badminton participants according to the training period. The subjects for the study were 12 healthy men composed of the badminton exercise group (n=6), and the control group (n=6). The cardiorespiratory function and blood fatigue variables were measured 4 times in all the subjects before the exercise program and after at the end of the preparatory period(1 week), competition period(2 weeks), and recovery period(1 week). The findings of this study were as follows; There was significant difference in V ˙O2max between two groups of badminton training in competition period. No significant differences in RER, BFmax, and HRmax between two groups. The result of blood fatigue had significant difference in group, and the result of time and group/time had significant difference among group, time and group/time.

This study has been conducted to analyze and find out the “impact of the type of badminton games on players" physique and physical strength”. The research subjects include 23 badminton players from B · K region registered in the Korea Badminton Association, including seven single match players, eight doubles match players and eight mixed-doubles match players who have recently participated in fall badminton championships. The measurement items have been comprised of physique examination (standing height, body weight, arm length, leg length, chest girth, thigh girth, lower leg girth) and physical strength examination (muscle strength, muscle endurance, flexibility, quickness, agility, general endurance). The average(M) and standard deviation(SD ) have been obtained by processing the measurements data using SPSS Ver 22.0 and the one-way ANOVA and Duncan have been adopted for verification of difference between groups and for follow-up analysis, respectively with the statistical significance level of (α)=.05. Research results in terms of verification of difference in physique and physical strength among different groups show that there is a more statistically significant difference in lower leg girth (p<.01) among those in single match group than in doubles match and mixed-doubles match groups and that that is more statistically significant difference in standing height (p<.01) among those in single match group than in doubles match and mixed-doubles match groups.

The purpose of this research is to discover the body composition and blood lipids of overweight middle school boys who participated in different events of sports. The research subjects were students from G school in B city in a total number of 21, seven of which participated in basketball, seven in jumping rope and seven in badminton. Tire training period was twelve weeks, three times a week for a session of 60 minutes, and items measured include body composition(body fat ratio and fat-free body mass) and blood lipids(TG, T-C, HDL-C and LDL-C). The data was analyzed through SPSS Ver 22.0, and the homogeneity of variables between different groups was verified using one-way ANOVA. The post-hoc analysis was conducted with Duncan testing while the differences between before and after within each group were verified with paired t-test. The research results revealed that the body fat rate were different between basketball and badminton, and fat-free body mass recorded differently between all three basketball, jumping rope and badminton. The differences between each group were greater in badminton than basketball and jumping rope. Also, TG out of blood lipids varied between all events of sports while T-C showed differences only in badminton. HDL-C was different in basketball and badminton while LDL-C was different in all events. The differences before and after between groups were absent.
