This study investigates the progress of obesity in men from childhood to adulthood, by analyzing the measurement references from the 5th Size Korea. It also seeks to analyze the characteristics of obese figures through the comparison of body proportions to normal-weight people, to provide a basic reference for the development of new size categories and improved pattern grading. The age range is divided into three groups: children (2-7), teenagers (13-18), and adults (19-39). The results of research into the characteristics of body proportions of obese figures and the classification of different figure groups of obese people are as follows. The ratio between width and circumference for each part of the body was investigated according to body weight that was grouped into three different categories of low, normal, and obese body weights. The result demonstrated that in all the ranges of age, the obese groups had the lowest ratio between width and circumference in having a thick body shape. According to the results that compared the ratio of the circumference of each body part divided by the waist circumference, the obese group showed a low ratio that indicates that they have a bigger waist circumference than other parts of the body. Two factors are identified as contributing to obesity in analyzing the ratio of the circumference of body parts divided by waist circumference. Using the factor loadings of the upper and lower body obesity, a cluster analysis was carried out and three different categories of obesity were defined; lower body obesity, abdominal obesity, and upper body obesity. The obese groups of children and teenagers were mostly in body shape with lower obesity and abdominal obesity, whereas the adults group showed the obesity present in the upper body obesity that have fewer cases in lower body obesity.

In this study, strength and durability are investigated using structural and vibration analyses on models 1 and 2 of a press in common use. Model 1 has a structure in which a punch is applied from the upper part to the lower part; however, model 2 a structure in which a punch is applied from the lower part to the upper part. Maximum displacements of models 1 and 2 are 0.018184 mm and 0.025498 mm, respectively. Maximum equivalent stresses of models 1 and 2 are 14.144 MPa and 18.58 MPa respectively. Maximum displacements are shown for the punches of both models; model 1 has less deformation than model 2. Model 1 has more durability than model 2, as determined by an investigation of the structural strength. Using natural frequency analysis, model 1 was found to have maximum deformation in the upper part of punch. Mode1 2 has its maximum deformation in the column part of the body and the upper part of the fixed pin. Using harmonic stress analysis, the maximum deformations were found on the punch part and column part of the body in the cases of models 1 and 2, respectively. As the maximum total deformation and equivalent stress in the case of model 2 are shown to become 40 times those values of model 1, the vibration durability of model 2 can be seen to be weaker than that of model 1.

Pictorial Structures(PS)는 동적 프로그래밍을 이용하여 인체의 포즈 추적 및 인식 하는 것에 매우 효과적인 방법으로 알려져 있다. 본 논문에서 상반신 포즈는 PS와 Particle filter(PF)에 의한 동적 프로그래밍 기법으로 추적된다. PF와 같은 동적프로그래밍에서 마코프 연쇄 (Markov Chain) 기반 동적 움직임 모델은 높은 자유도를 갖는 상반신 포즈를 예측하기 어려운 단점이 있다. 본 논문에서 제안하는 방법은 키포즈 기반 예측분포이며, 이것은 상반신 실루엣과 키포즈(Key Pose)들 사이의 유사도를 참고하여 파티클(Particle)을 적절히 예측하는 것이다. 실험 결과를 통해 제안된 방법은 기존 방법 성능을 70.51% 향상시킨 것을 확인하였다.

The purpose of this study presents bra pattern using the 3D measurements of the upper body subject to women in their 30's. Brassieres available in the market are mostly designed for straight body shape and many women seem to have experienced bearing discomfort in a great extent as they grow older. Brassieres should be designed to cover diverse body types and the accurate measurement of body type and breast shape is needed to accomplish that. As for the study method, 3D human body types were analyzed with RapidForm 2006, and the upper-body types and breast shapes were statistically classified through technical statistics analysis, cluster analysis, t-test, variance analysis, and cross analysis. The wearing tests went through the comparison of the brassieres of three makers in the market and the experiment brassieres(first and second) and then the evaluations were made by the subjects, the outer appearance assessment by experts, and 3D measurements. The results of this study showed that the evaluation of experiment brassieres was excellent in every item, and the significant difference was found out particularly in the items of pressure, rear center, front center, breast underneath, adequate level by wing, and adequate level by armhole. According to the results of 3D evaluation, experiment brassieres had a highest point in fitness with no physical pressure at the wing part and no overall deviation at the cup part.

본 논문에서는 다관절체 추적을 위해 기존에 물체 추적에 자주 이용되는 파티클 필터를 확장한 계층적 파티클 필터 방법을 제안한다. 칼라 특징은 부분 겹침, 회전등에 강건한 특징을 가지고 있어서, 칼라 기반 파티클 필터는 물체 추적에 널리 쓰이고 있다. 다관절체 추적에서 상태 벡터는 높은 차원을 가지기 때문에 기존의 파티클 필터를 이용해 바람직한 추적 결과를 얻기 위해서는 많은 수의 샘플이 요구된다. 이러한 문제점을 해결하기 위해, 본 논문에서는 이미 알고 있는 다른 신체 부위의 위치를 이용해 계층적으로 신체 부위를 추적한다. 계층적 추적 방법에 의해 복잡한 환경에서 강건한 추적을 위한 샘플의 수를 줄일 수 있었다. 또한 포즈를 인식하기 위해 상박과 하박의 각도를 이용한 SVM(Support Vector Machine)을 이용해 8개의 포즈를 분류한다. 실험 결과는 세안한 방법이 기존의 칼라 기반의 파티클 필터보다 효율적임을 보여준다.

In this study, seven models with distinctly different body types were researched and explanatory variables were reviewed. Review was done by using body measurements and the measurements of the appropriate bodice patterns in 1D, 2D, and 3D measurement methods in order to review the pattern making system and the equations for calculating the dimensions of the sleeve caps, which are readily available. Data on human bodies, which can be the criteria for each body part required for the new system for making sleeve cap part, were selected considering conditions such as items with a significantly high contribution rate from the results of regression analysis and the easiness of measurement. As a result of research, an explanatory variable required for the system for making sleeve caps with high general use was extracted. All items with the exception of the waist circumference and upper arm circumference were about the measurement of the form of human bodies, which were newly set in this study. As a result of this study, the equations for calculating the dimensions of each part of the sleeve caps showed distinct differences in comparison to the conventional system of construction.

The purpose of this study is to provide basic information for the development of well-fitting and comfortable brassieres for women in their 30s, based on the classification of breast shapes by utilizing 3D body measurement data of women in the age group. The result of processing the measurements from the 3D body scan data through RapidForm 2006 shows that while the vertical body measurements decrease, the horizontal measurements, which indicates the degree of obesity, increase proportionally with age. Also, the relevant measurements for upper breasts increase proportionally with age, while the measurements for lower part of the breasts decrease as the degree of sagging increases. Four composition factors of the breasts were identified through the factor analysis: Factor 1 is the level of volume in the breasts and the surrounding area; Factor 2 is the position of nipples and the shape of upper part of breasts; Factor 3 is the position and vertical length of the breasts; Factor 4 is the shape of lower part of breasts; and Factor 5 is the shape of inner part of breasts and degree of width between both breasts. The breasts have been categorized into three distinctive shapes: Breast Shape 1, Breast Shape 2 and Breast Shape 3. According to the results of the cluster analysis, the largest percentage (36.68%) of women in their 30s falls into the category of Breast Shape 2 with small volume and flat upper breasts, followed by Breast Shape 1 (32.66%) with large volume in the upper and lower parts of breasts, and large side to side area, and Breast Shape 3 (30.65%) with average volume and width between breasts.
