우진희(Jin Hee Woo),김우비(Woo Bee Kim),김대원(Dae Won Kim),이기웅(Ki Woong Lee),이선형(Seon Hyeong Lee),이현석(Hyeon Seok Lee) 한국추진공학회 2021 한국추진공학회 학술대회논문집 Vol.2021 No.5

배터리 방식의 멀티콥터는 비행 중 무게가 변하지 않아 산술적으로 호버링 시간을 계산할 수 있다. 반면, 엔진-배터리 하이브리드 추진 멀티콥터의 경우에는 비행 중 연료 소모로 인해 중량, 요구출력 및 연료소모율 등이 동시에 변하게 되어 호버링 시간을 직관적으로 예측하기엔 어려움이 있다. 본 논문에서는 직렬형 하이브리드 추진 멀티콥터에 대해, 비행 전과 후의 무게로 호버링 시간을 계산할 수 있는 방정식을 도출하고, 실측값과의 비교를 통해 해당 기법의 실용성을 보인다. Engine-battery hybrid powered multi-copters consume fuel while in flight, consistently causing their total weight, required power, and fuel consumption rate to change. Because these variables are in constant fluctuation, it is difficult to predict how long they able to flight. In this study, we derive an equation to predict the hovering time of serial hybrid powered multi-copters with only their weights before and after flight, and demonstrate the practicality of the equation by comparing it with actual flight test results.

우진희 ( Jin Hee Woo ),여남회 ( Nam Hwoeh Yeo ),강성훈 ( Sung Hwun Kang ) 한국스포츠정책과학원(구 한국스포츠개발원) 2008 체육과학연구 Vol.19 No.3

본 연구는 소아ㆍ청소년 IDDM 남자 환자(DM군, n=10)와 건강한 남자 어린이(HT군, n=10)를 대상으로 12주간 유산소 운동프로그램 참여 전과 후의 지질 profiles, 항산화효소 유전자 발현, 그리고 산화물 생성의 차이를 비교하는데 그 목적이 있었다. 측정 시기는 훈련 전과 훈련 후 하였으며, 신장, 체중, 체지방, WHR, 혈압, 최대산소섭취량을 측정하였고, 혈중 지질 profiles, HbA1c, ox-LDL, DNA damage, total RNA를 분석하였다. 연구결과, 체질량지수(BMI), 체지방률, 최대산소섭취량은 그룹 간, 시기 간 차이가 없었다. 이완기 혈압은 HT군에 비해 DM군이 높게 나타났으며(p<.05), TC와 HDL-c, ox-LDL은 그룹 간, 시기 간 차이가 없었다. HbA1c는 DM군이 HT군에 비해 높았지만(p<.05), 트레이닝에 의한 변화는 나타나지 않았다. 항산화 효소 유전자 발현은 방어 기전에 따라 다른 양상을 보였으며, 조직손상과의 관계도 일관성을 보여주지 않았다. DNA damage는 트레이닝 후 DM군에서 유의한 증가가 나타났다(p<.05). 따라서, 항산화 방어역량이 약한 IDDM 환자에게 운동은 일시적인 DNA damage를 수반한다고 보지만, 트레이닝에 의해 일부 항산화 효소 유전자 발현이 증대될 수 있으며, 당화 Hb 개선을 위해선 역치수준 이상의 운동강도와 더불어 무산소성 트레이닝이 필요할 것으로 사료된다. The purpose of this study was to compare the differences between before and after 12 week aerobic training on lipid profiles, antioxidant enzyme gene expressions, and oxidative products in children with IDDM. We therefore studied 20 children (age, 11.9±1.85 years; 10 boys) with IDDM and 10 age-matched healthy controls during 12 week of moderate intense running exercise. Blood samples for lipid profiles, HbA1c, ox-LDL, 8-OHdG, and total RNA were drawn before, and after training. There were no differences of BMI, body fat, and VO2 max between groups and periods. Also, there were no differences of TC, HDL-c, and ox-LDL between groups and periods. In IDDM, baseline DBP, and HbA1c was higher than that of controls(p<.05). And exercise-induced DNA damage peak occurred greater than control(p<.05). Antioxidant enzyme gene expression displayed different aspect according to antioxidant defense mechanism, and there was no consistency that related to tissue damages. Therefore, during or immediately after intense exercise, temporary alterations in the tissue damage occurred in children with IDDM who are at weakened antioxidant defence capacity. However, some kinds of antioxidant enzyme gene expressions magnitude by long term training, and anaerobic exercise include in training may help to improve the normalization of glycated Hb.

운동과 산화질소의 기능

  There is increasing evidance that nitric oxide (NO) is an important hemodynamic and metabolic regulator during the performance of physical activity. Futhermore, there are adaptations in this system as a result of exercise training that likely contribute to increased functional capacity and the cardioprotective effects associated with higher fitness levels. Exercise has particular efficacy in restoring dysfunction of the vascular endotherial NO system, which is becoming established as a precursor to the atherosclerotic process.<BR>  The production of NO from L-arginine is catalysed by the nitric oxide synthase (NOS), which involves NOS Ⅰ, NOS Ⅱ, and NOS Ⅲ, NO has been implicated in such diverse processes as vasodilation, inhibition of platelet aggregation, immune function, cell growth, neurotransmission, metabolic regulation and excitation-contraction coupling. The vast animal literature, together with more recent human studies, indicates that endurance exercise training for a period ranging from days to several weeks enhances basal release of NO from aorta, active and inactive muscle and coronary arteries. This adaptation may contribute to the reduction in resting blood pressure and increase in blood flow to skeletal muscle. Also, NO system is modified by training in the setting of cardiovascular disease in humans and that these effects may contribute to increased functional capacity. Recent animal study data also suggest that this benefit may extend to skeletal muscle NO, which appears, among other functions, to mediate glucose uptake during exercise. However, the role of NO in the coronary circulation and skeletal muscle, particularly with regard to glucose uptake, is yet to be elucidated.

우진희 ( Jin Hee Woo ),강성훈 ( Sung Hwun Kang ) 한국스포츠정책과학원(구 한국스포츠개발원) 2008 체육과학연구 Vol.19 No.4

본 연구는 남자초등학생을 비만군(n=20, 나이=11.15±1.42세)과 정상군(n=10, 나이=10.70±0.95세)으로 나누어 개별 열량 소비 트레이닝을 12주간 실시하여 산화-항산화체계에 미치는 영향을 비교하는데 목적이 있다. 신체구성, 호흡순환기능, 혈청지질, 항산화효소, 조직손상 인자들을 분석하였으며, 연구결과 비만군은 체지방률, 수축기와 이완기 혈압, TG, LDL-c, ox-LDL, 8-OHdG 등이 정상군에 비해 유의하게 높다는 것과 이에 반하여 HDL-c, 항산화효소인 SOD 수치는 정상군과 비교하여 유의하게 낮게 나타났다. 또한 12주간의 개별 열량소비 트레이닝을 통해 정상군과 비만군 모두 ox-LDL 수치와 GPX활성이 유의하게 증가되었다. 따라서, 비만아동은 비만에 의한 조직손상과 항산화 방어 역량의 저하로 산화·항산화 체계의 불균형을 일으키며, 산화적 스트레스를 높여 혈관의 염증반응을 증가시켜 결국 혈관을 손상시키고 심혈관질환위험을 가속화시키는데 영항을 줄 수 있음을 시사한다. 또한 12주간의 개별열량 소비 트레이닝을 통하여 항산화효소 활성에 긍정적인 영향을 주어 체내의 산화·환원의 체계를 정상화시켜 심혈관계 스트레스 감소에 긍정적인 영향을 줄 수 있을 것으로 사료된다. The purpose of this study was to compare the differences between before and after 12 week individual calory consumption training on oxidation-antioxidation in obese children. All the subjects divided into obese training group(n=20, age=11.15±1.42) and normal training group(n=10, age=10.70±0.95). Before and after training, we measured that body composition, cardio-pulmonary function, serum lipid, antioxidant enzyme, tissue damage factors. There were differences in body fat, VO2 max, systolic and diastolic blood pressure, TG, HDL-c, LDL-c, ox-LDL, 8-OHdG, and SOD levels between groups. Also, there were differences in ox-LDL and GPX levels between pre and post. In conclusion, body fat, blood pressures, TG, LDL-c, ox-LDL, and 8-OHdG levels were higher and VO2 max, HDL-c, and SOD levels were lower in obese children than in normal children. But, GPX activity in obese children with regular exercise were found to be similar to those of normal children. These results indicated that increased cardiovascular stress and antioxidant imbalace begins in childhood in obesity. However, individual calory consumption training can enhance antioxidant capacity in obese children.

우진희(Woo Jin-Hee),박성철(Park Sung-Chul) 한국웰니스학회 2018 한국웰니스학회지 Vol.13 No.4

본 연구는 여자대학생을 대상으로 섭식제한(DG), 유산소운동(EG), 섭식제한과 유산소운동(DEG) 그룹으로 나누어 체중, 비만의 개선, 기초체력 및 심리적요인에 미치는 영향을 분석하였다. 실험은 8주간 주 5회 실시하였으며, 섭식제한그룹은 1일 에너지 섭취열량 중 300㎉를 제한하였고, 유산소운동그룹은 러닝머신을 이용하여 300㎉를 소비시켰으며, 섭식제한과 유산소운동을 병행한 그룹은 섭식제한과 러닝머신을 이용하여 각각 150㎉를 제한과 소비시켰다. 8주간의 처치 결과, 신체조성의 경우 DG에서는 체중(p<.011), BMI(p<.008)가 감소하였고, EG와 DEG에서는 체중(p<.044, p<.017), 체지방량(p<.047, p<.018), BMI(p<.03, p<.008), 체지방률(p<.036, p<.015), WHR(p<.049, p<.027)이 유의하게 감소하였다. 기초체력의 경우 EG에서는 악력(p<.003), 윗몸일으키기(p<.02), 20m 왕복달리기(p<.001)이 유의한 차이를 나타내었고, DEG에서는 악력(p<.046), 윗몸일으키기(p<.001)에서 유의하게 향상되었다. 심리적요인의 경우 DG에서 체형만족도(p<.02)가 향상되었고, EG와 DEG에서는 체형만족도(p<.003, p<.002), beck 우울척도(p<.015, p<.000), 자아존중감척도(p<.008, p<.003)에서 유의하게 향상되었다. 따라서 본 연구의 결과로부터 여자대학생들의 다이어트 방법 중 섭식제한, 유산소운동을 단독으로 실시하는것 보다 섭식제한과 유산소운동을 적절하게 병행하는 것이 체중감소와 기초체력의 향상, 그리고 심리적 요인의 개선에 가장 효과가 있을 것으로 판단된다. The purpose of this study was to investigate the effect of 8week dietary restriction(DG), aerobic exercise(EG) and dietary restriction with aerobic exercise(DEG) on weight, improvement of obesity, basic physical fitness and psychological factors of female college students. Experiments were conducted 5 times a week for 8weeks, groups were classified into DG(300㎉ intake restriction per day energy intake), EG(300㎉ consumption via treadmill training), and DEG(150㎉ intake restriction and 150㎉ consumption via treadmill training). The results of 8-week treatment, in case of body composition, weight(p<.011) and BMI(p<.008) were decreased in DG, and weight(p<.044, p<.017), body fat(p<.047, p<.018), BMI(p<.03, p<.008), body fat%(p<.036, p<.015) and WHR(p<.049, p<.027) were decreased in EG and DEG. In case of basic physical fitness, grip strength(p<.003), sit-up(p<.02), and 20m shuttle run(p<.001) were improved in EG, and grip strength(p<.046) and sit-up(p<.001) were improved in DEG. In case of psychological factor, there were significant differences in body shape questionnaire(p<.02) was improved in DG, and body shape questionnaire(p<.003, p<.002), Beck depression inventory(p<.015, p<.000) and self-esteem questionnaire(p<.008, p<.003) were decreased in EG and DEG. In conclusion, combined treatment of eating restriction with aerobic exercise was the most effective way to improvement of weight, physical fitness and psychological factors in female college students rather than respectively alone treatment.

노희태(Roh, Hee-Tae),우진희(Woo, Jin-Hee),조수연(Cho, Su-Youn),양정수(Yang, Jung-Su),유신환(Yoo, Shin-Hwan) 한국체육과학회 2015 한국체육과학회지 Vol.24 No.5

The purpose of the this study was to investigate the effects of trekking pole during up-hill walking on serum cartilage oligomeric matrix protein(COMP), muscle damage and fatigue variables in obese females. The subjects for this study were 10 obese females who had more than 30% of body fat. Each of them performed up-hill walking without trekking poles(Control) and with trekking poles(Pole) at 50%HRR during 35 minutes on a treadmill. The treadmill was set 25% up-hill inclination. Serum COMP levels, indices of muscle damage[creatine kinase(CK) and lactate dehydrogenase(LDH)], and fatigue(lactate) were measured before, immediately after, and 2h after walking. The levels of COMP were significantly increased at immediately after walking compared to those at before, significantly decreased at 2h after walking in Control and Pole(p<.05). And the levels of COMP were significantly lower in Pole compared to Control at immediately after walking(p<.05). The levels of CK and LDH were significantly increased at immediately after walking compared to those at before in Control p<.05) These results suggest that up-hill walking can induce increase of serum COMP levels and muscle damages. It is suggested, however, that up-hill walking with trekking poles could reduce cartilage and muscle damages.
