The prevalence of obesity at all ages in increasing epidemically worldwide. There were many study of an indirect method on fat mass measurement in obesity, but were few study to determine the possible relationships between local fat deposition and health-related fitness parameters in overweight and obesity. We has reviewed on the somatotype characteristics, ideal posture and biomechanics, and adipose tissue of connective tissue, myofacia continuity. We consider that these unique 'whole systems' view is of vital importance to understanding the role of adipose tissue in musculoskeletal system and to application of body shape correction program.

자외선보다 파장이 짧은 X-선은 투과력이 매우 좋아 산업 분야 및 의료분야에 융합되어 많이 사용되고 있다. 특히 산업분야에서는 비파괴 검사 장비인 x-ray를 이용하여 금속과 같은 제품의 생산 과정에서 발생할 수 있는 금속 내부의 이물질에 검출에 대한 연구가 다양하게 이루어지고 있는 실정이다. X-ray 영상 이미지를 디지털 방식으로 획득하는 DR(Digital Radiography) 방사선 촬영 방식의 확산으로 디텍터의 사용이 활발해지고 있으나 내부의 센서 잡음 및 감도에 따라 이물질 검출이 불가능한 경우도 발생하고 있다. 금속 제품을 생산할 경우 이물질의 혼입으로 생산 제품의 불량률이 높아질 수 있기에 정확한 검출이 필요하다. 이에 본 논문에서는 금속 내부의 이물질과 같은 결함 검출의 효율을 향상시키기 위하여 획득한 X-ray 이미지의 보정 모델을 제안한다. 제안 모델을 통하여 금속 제품 생산 공정의 불량 검출에 적용하면 제품 결함의 검출을 정확하고 신속하게 처리할 수 있을 것으로 기대된다.

This study aimed to typify men's beliefs, perceptions, values, and attitudes, regarding foundation underwear, and examine the characteristics of each perception. Thirty-one statements on men's correctional underwear were selected, and Q classification was conducted with 20 men in their 30s and 40s as the P samples. Factors were extracted using principal component analysis and varimax rotation. Type 1 was the "fit improvement disadvantage cover type", which covered the target area, and improved the clothing fit. Type 2 was referred to as the "highlighting the advantages of chest correction" type, that was used to improve chest correction and exercise efficiency. "Positive wear for compensation of the abdomen", was listed as type 3, and was worn for abdominal correction. It was believed that type 3 could be used to correct body shape even if it was uncomfortable. Type 4, the "hip-up correction functional type", emphasized functionality based on its hip-up correction design.

This study investigated the demand for functional clothing that compensates for the physical deformation of women due to aging. For this, the degree of perception of physical deformation at the new silver generation was examined. The demand for functional clothing that corrects body shape and posture according to differences in age and degree of perception was analyzed. Study participants(n=138) were women who ranged from 55 to 65 in age. Perception of physical deformation was investigated in the categories of deformation of body posture, cognition of joint pain, and deformation of body shape. Analysis results showed that cognition of joint pain was the largest of the three elements of body deformation, and each element had a high correlation between each other. Perception for degree of body deformation for women in their 50's and 60's was similar. These results show that changes in posture or body shape occur severely from the late 50's, and this appears as joint pain. The group with a high perception of posture deformation showed an especially high demand for functional clothing that corrects body shape and posture. The group with a high perception of body shape deformation had high demand for functional clothing that corrects body shape by lifting the hips and the breasts, and making the abdomen and waist slimmer. The results of this study show that women of the new silver generation are attuned to deformations in body shape and posture as well as joint pain beginning in their mid-fifties. There is a need to develop functional clothing to correct posture and body shape for the new silver generation women.

In order to study the resistance test technique for the submerged body in Large Cavitation Tunnel (LCT), DARPA Suboff, submarine model publicly available was manufactured. DTRC released the resistance test data of DARPA Suboff conducted at ship speeds up to 18.0 knots in high-speed towing tank in 1990. As LCT is considered restricted waterways with walls, the resistance test results must be corrected with three wall blockage effects called buoyancy effect, solid blockage effect and wake blockage effect. Before correction, the resistance of LCT was 16~20 % higher than that of DTRC. After correction, the resistance and the resistance coefficients were compared with those of DTRC. The corrected resistance of LCT shows good agreement with that of DTRC. The residual resistance coefficient shows the difference according to the calculation method of buoyancy and frictional resistance coefficient. This paper suggests the best way for the calculation of residual resistance coefficient, On the basis of the present study, it is thought that the operating conditions for the propeller cavitation and noise tests can be drawn through LCT tests.

본 논문에서는 가상원통을 이용하여 기하학적인 의복시뮬레이션에서 발생하는 의복 3차원모델의 관통을 고속으로 검사하고, 의복 3차원모델을 수정하는 새로운 방법을 제안한다. 의복을 개인 캐릭터에 기하학적으로 맞추는 경우, 의복이 인체를 국부적으로 관통하는 경우가 있다. 본 방법은 인체모델과 의복모델을 둘러싼 가상원통을 설정하고, 가상원통을 이용하여 관통지점의 후보들을 한 번에 압축하여, 후보 중에서 관통지점을 찾는 방법이다. 관통된 부분에서는 의복모델의 꼭지점을 밀어내거나 삼각형을 분할하여, 의복모델을 기하학적으로 수정한다. 이 방법은 바운딩볼륨을 이용하여 반복적으로 관통후보를 압축하는 물리적인 방법에 비해 고속처리가 가능하다.

영상센서 중 적외선 센서는 시간경과 및 작동/비작동 반복에 따라 적외선 광원에 대한 응답특성이 조금씩 변화하며, 그 결과 영상품질이 저하된다. 그래서 인공위성에 탑재되는 적외선 센서의 경우 정상적인 임무수행을 위해 교정용 흑체로 주기적인 비균일 응답특성 보정을 실시할 수 있도록 해야 한다. 본 논문에서는 비균일 응답특성 보정을 위해, 적외선 센서의 파장대역 $3.3{\sim}5.2{\mu}m$에서 흑체 방사율이 0.995이상 평균온도차 $1^{\circ}C$ 이하가 되도록 V-그루브(groove) 타입의 흑체를 설계하였다. 성능검증을 위해 흑체의 방사율과 표면온도를 측정하여 검증하였으며, 그 결과로부터 비균일 응답특성 보정오차를 산출하였다.

최근 학생 및 사무직 종사자의 자세 불량으로 인한 척추계 질환의 발병율이 증가하고 있으며, 바른 자세 유지를 돕기 위한 다양한 연구가 수행되었다. 기존 연구에서는 의자 방석부분에 멤브레인 센서 또는 압력센서를 배치하여 무게의 편중을 보거나, 사용자를 구속하는 센서를 부착하여 체위변환을 측정하였다. 본 연구자는 선행연구에서 점착성 겔시트로 간편히 몸에 부착할 수 있으며, 사용자의 자세 및 체위 변화를 실시간으로 측정하여 출력하는 센서 디바이스를 개발하였으나 센서값의 정확성에서 한계점을 보였다. 본 연구에서는 체위변환 센서 디바이스의 성능을 개선하고, 각도변환 측정값의 정확도를 정량적으로 평가하는 연구를 수행하였으며, 오차율 2.53%의 높은 정확도를 확인하였다. 향후 연구에서는 멀티미디어 요소가 추가된 자세교정 훈련 컨텐츠를 보다 다양화하여 실제 사용자를 대상으로 하는 추가 연구가 필요한 것으로 사료된다.

Lifespans are increasing and many consumers are interested in health issues in these busy modern days, developing functional clothing that can be worn everyday is one of the competitive solutions in the oversaturated clothing market. When developing a new item with a fresh idea, it is important to look into prior art beforehand to avoid unnecessary intellectual property right-related disputes. This study investigates Korean domestic patents and utility models about functional clothing in terms of human body performance and health promotion in order to suggest essential data to relevant developers. We selected 324 patents and utility models and made an analysis according to the year, functions, applied technologies, frequency of claims, target wearers and item types. We found problems in current functional clothing patent application trends and suggested new aspects when developing innovative functional clothing items. Data was limited to Korean domestic patents; however, this study is still meaningful giving references to technology roadmaps and encouraging new intellectual property development.

This study was performed to measure the posture correction effect of wearing ergonomic experimental clothing. Two types of experimental clothing (A, B) were developed. Both of them reinforced the muscles surrounding the spine. Experimental clothing A was developed by reflecting the shape and position of the pectoralis major muscle, abdominal muscle, and latissimus dorsi muscle. Experiment clothing B was developed by reflecting the integrated form of those muscles. Subjects were males in their 20s~30s (n=32). They were divided into two groups based on their acromion distance (AD): the turtle neck syndrome group (n=16, AD=3.81cm) and the normal group (n=16, AD=1.27cm). The correction of body posture was detected by three index values: change of the cervical curvature angle, horizontal distance between the seventh cervical vertebra and tragion, and AD. The comfort and tightness of the clothing were also measured. The results showed that both types of experimental clothing corrected body posture and that turtle neck syndrome can be prevented by wearing these types of posture correcting clothing. Two index values were decreased: cervical curvature angle ($0.31{\sim}1.32^{\circ}$) and horizontal distance between seventh cervical vertebra and tragion (0.22~0.31cm). The chest was also stretched. The comfort was rated as good for both types of experimental clothing. These results indicate that the experimental clothing had a posture correction effect without any discomfort for daily living.
