The purpose of this study was to investigate a cross-sectional research of body compositions and fitness of participants in a sports facility. The subjects of this study were divided into control(male n=70, female n=37), health(HE, male n=80, female n=50), and swimming(SW, male n=53, female n=25) group as their participating exercise type. Anthropometry, body composition test, blood pressure, and physical fitness test were measured. In the males, fat free mass was higher, and fat ratio, and resting heart rate were lower in both exercise group than control group. And cardiovascular fitness and muscle strength were higher in SW than control group. In the females, fat free mass was higher in both exercise group than control group. HE showed lower resting heart rate and higher aerobic fitness and muscle strength compare to control group. And there were no significant differences between SW and HE group in body composition and fitness factors. Cardiovascular and muscular fitness were related with FFM positively, and fat ratio inversely. The university students who are participated in sports facility regularly had improved body composition and the male of SW group, and the female of HE group had higher fitness level than non-exerciser.

Hybrid fabrication process of additive manufacturing and direct writing for a 4×4 mm matrix flexible tactile sensor

우상구,이인환,이경창 대한기계학회 2015 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.29 No.9

Various machines require data from their external environments for safety and/or accuracy. In this respect, many sensors thatmimic the human sensory system have been investigated. Among these, tactile sensors may be useful for obtaining data on theroughness of, and external forces acting upon, an object. Several tactile sensors have been developed; however, these are typicallyfabricated via a series of complex processes, and hence are unsuitable for volume manufacturing. In this paper, we report a fabricationprocess for a 4×4 mm matrix flexible sensor element using layered manufacturing and direct-write technology. A compositecomposed of photocurable resin and Multi-walled carbon nanotubes (MWCNTs) was used as the sensing material. The MWCNTswere mixed with the photocurable resin using ultrasonic dispersion, and the liquid mixture exhibited excellent piezoresistive propertiesfollowing curing using ultraviolet light. The used photocurable resin is flexible and elastic after curing. Therefore, the compositematerial can be bent and deformed. To use this composite material with the flexible sensor, dispensing characteristics wereexamined using direct-write technology. For the acquisition of sensor data, a commercial pin-header was inserted and photocurableresin was filled up to the height of pin-header and cured . Then, the composite material was dispensed onto the pin-header as a sensingmaterial. Using this process, a flexible sensor with piezoresistive properties was formed.

Effect of Visceral Adipose Tissue on Atherogenic Lipoprotein-lipids in Circulating Plasma

우상구 한국운동영양학회 2004 Physical Activity and Nutrition (Phys Act Nutr) Vol.8 No.3

Little is known about how visceral adiposity and apolipoprotein CIII in apo B-containing lipoproteins influence plasma triglyceride (TG) concentrations. The purpose of this study was to determine the relationships of visceral adiposity and apo CIII in apo B-containing lipoproteins with plasma TG concentrations in men and women. Procedure: A subgroup of 46 men (n = 20, aged 29.1-33.4 yr) and women (n = 26, aged 29-1 33.8 yr) were recruited from an ongoing population study at our institution. Anthropometric variables including weight, height, and waist circumference were measured using standard procedures, and body mass index was calculated (kg/m2). Visceral adipose tissue (VAT) was measured with a magnetic resonance imaging. Plasma apolipoproteins, lipids, glucose, and insulin were measured after an overnight fasting. Results: The men had significantly higher waist circumference, glucose, and TC/HDLC ratio than the women, while the women had significantly higher HDLC and apo AI than the men. Of particular, this is the first study to report that VAT and apo CIII in apo B-containing lipoproteins were independent predictors in determining plasma TG concentrations in Korean adults. Conclusion: Among the obesity indices measured in the current study, VAT and waist circumference were more consistently associated with the atherogenic lipoproteinlipids( i.e. triacylglycerol, apo CIIIs), fasting insulin and glucose. Consequently, the current study suggest that information on VAT and apo CIII in apo B-containing lipoproteins may provide additional information on the development of atherogenic lipid profiles and thereby atherosclerosis.

Hematopoietic stem cell transplantaion(HSCT) has been used to treat a variety of non-malignant and malignant lymphohematopoietic disease. It was reported that performance status(ECOG PS) is associated with nutritional status which is most affective factor for treatment and recovery in cancer patients, and ECOG PS is also independent prognostic factor in patients. This study investigated that the effects of ECOG PS on body composition, nutritional indices and bone metabolism before and after a year post-HSCT. Reports of 44 patients undergoing HSCT were analysed in this study. According to their performance status before and after a year post-HSCT, patients were divided into a improved(or maintained) group A(n=28) and a decreased group B(n=16). Body fat ratio and waist hip circumference of group B were higer than group A(p<.05). Hemoglobin concentration increased after HSCT in group A(p<.05). Alkaline phosphatase was higher in group A than group B(p<.05). The results indicate that decreased ECOG PS related with high body fat ratio and waist hip circumference, and maintaining ECOG PS contribute to increase of blood hemoglobin level. Further research is needed for intervention to improve ECOG PS intervention.

노인의 균형자신감과 골밀도 및 근감소증 지표와의 연관성

우상구 한국스포츠학회 2019 한국스포츠학회지 Vol.17 No.1

본 연구는 노인의 균형자신감과 골밀도 및 근감소증 지표와의 연관성을 검증하고, 추가적으로 균형자신감에 대 한 세부적인 독립예측변인을 파악하는 것에 주요 목적을 두었다. 연구대상은 경기도 지역의 60세 이상 노인 308명(남: 67명, 여: 241명)을 대상으로 하였으며, 균형자신감은 한국어판 활동 특이적 균형자신감 척도를 이용하여 조사하였다. 골밀도는 이중 에너지 X-ray 방사선 흡수법 원리를 이용하여 요추, 대퇴 경부, 전신을 측정하였으며, 근감소증 지표는 악력, 보행속도, 사지근율비율 지수를 포함하였다. 균형자신감은 전신 골밀도(R=.278, P<.001), 요추 골밀도 (R=.157, P=.008), 대퇴 경부 골밀도(R=.383, P<.001), 보행속도(R=.490, P<.001), 악력(R=.399, P<.001), 사 지근육비율 지수(R=.242, P<.001)와 유의한 상관관계가 있는 것으로 나타났으며, 균형자신감에 대한 독립예측인자 는 보행속도(β=.338, P<.001), 악력(β=.202, P=.009), 대퇴 경부 골밀도(β=.202, P=.018)인 것으로 나타났다. 노인의 균형자신감에 있어서 보행속도, 악력, 대퇴 경부 골밀도는 독립적인 역할을 할 수 있는 요인인 것으로 나타났으 며, 노년기 규칙적인 걷기 운동, 체중부하를 통한 근력 운동프로그램은 노인의 균형자신감 증진과 더불어 낙상예방에 적절한 대응방안이 될 수 있을 것으로 생각된다. This study examined the association of bone mineral density (BMD) and sarcopenia component with balance confidence in elderly. Method: This was a cross sectional study involving 308 (men: 67, women: 241) elderly. Korean version of activities-specific balance confidence (ABC) scale was used to assess balance confidence. BMD analysis was performed with a dual-energy X-ray absorptiometry (DXA). Measured sarcopenia components included appendicular skeletal muscle mass (ASM) index, hand grip strength (HGS), gait speed (GS). Results: Balance confidence was significantly associated with total BMD (R=.278, P<.001), lumbar BMD (R=.157, P=.008), femur neck BMD (R=.383, P<.001), ASM index (R=.242, P<.001), HGS (R=.399, P<.001), and GS (R=.490, P<.001). Multiple linear regression analysis showed that GS, HGS, and femur neck BMD were independent predictors for balance confidence. Conclusion: The current findings of the study suggest that promotion of resistance exercise and weight-bearing exercise should be incorporated in interventions against balance confidence with normal aging.

The purpose of this study was to investigate whether or not the ONB3 C825T gene polymorphism would modulate obesity and its metabolic syndrome markers responses to 12-week of aerobic exercise. Subjects of BMI>25 ㎏/㎡ obesity middle aged women. Measured of body composition, blood pressures, blood lipids, blood glucose, insuin, HOMA-IR and ONB3 C825T gene polymorphism. Then all the participants underwent a l2-week (3 days/week) aerobic exercise. The GNB3 genotype was a significant modulator in determining some of the metabolic syndrome markers (i..e, TG (p=0.018), and HOMA-IR (p=0.033) responses to 12-week of aerobic exercise. The current findings of the study suggest that the GNB3 C825T gene polymorphism can partially be a genetic modulator of obesity and its related metabolic syndrome markers responses to exercise training in this study population.
