In this study, the 4th (1997) and 6th (2013) direct measurements of Size Korea compared the changing shape of women between the ages of 12 and 18. Comparing the items of height and length, the height and shoulder height were significantly reduced, the waist height was not significantly different, and the height of the upper hip was significantly increased, resulting in a smaller upper torso ratio and a higher lower torso rate. The width and thickness associated with human obesity, the circumference items and obesity levels often increased significantly with the change of the times, indicating that the overall body size was increased and that the chest area was changed to a cylindrical shape with changes in the breast equilibrium. Comparing agespecific measurements with graphs analyzing the trend of change in growth, the results showed that the change in 1997 was minimal since age 14; however, a continuous increase was achieved in 2013 that corresponded to the age at which growth is complete. The results of these studies are expected to be used as basic data to predict pattern design, body implementation, and trends in shape changes for young women.

The purpose of this study is to create a shirt sloper suitable for an elderly male body shape by producing virtual models using a 3D-virtualization program, making a torso prototype using the Yuka CAD system, and employing 3D simulation to virtualize and calibrate the model. First, the following three types of obese dummies are implemented through the CLO 3D program: Type 1 exhibits body fat in the lower body; Type 2 exhibits an obese abdomen; and Type 3 displays a balanced form of obesity. Second, for the design of the shirt pattern, the waist back length (measured value+1), back armhole depth (C/10+12+3+0.5~1.5), front armhole depth (back armhole depth 0~1), front interscye (2C/10-1+0.5-0.5), armscye depth (C/10+2+3.5+ 0.5), back interscye (2C/10-1+1), front chest C (C/4+2.5+1), back chest C (C/4+2.5-1), front hem C (C/4+2.5+1(+2)), back hem C (C/4+2.5-1(+2)), cap height (AH/3-5), and biceps width (Front AH-1, Back AH-1) are calculated. Third, the virtual attachment of the shirt pattern is resolved by increasing the front and back armhole depths, and the front and rear wrinkles are improved by adding a back armhole dart. The front hem lift and lateral pull caused by the protrusion of the abdomen are amended by increasing the margin of the chest, waist C, and hip C, with the appearance improved by balanced margin distribution in the front, back, and side panels. The improved retail pattern with an increase in the front armholes C was balanced on the torso plate.

Purpose Various methods for reducing radiation exposure have been continuously being developed. The aim of this study is to evaluate effectiveness of dose reduction, image quality and PET SUV changes by applying combination of automatic exposure dose(AEC), automated dose-optimized selection of X-ray tube voltage(CAREkV) and sinogram affirmed iterative reconstruction(SAFIRE) which can be controled by user. Materials and Methods Torso, AAPM CT performance and IEC body phantom images were acquired using biograph mCT64, (Siemens, Germany) PET/CT scanner. Standard CT condition was 120 kV, 40 mAs. Radiation exposure and noise were evaluated by applying AEC, CAREkV(120 kV, 40 mAs) and SAFIRE(120 kV, 25 mAs) with torso phantom compare to standard CT condition. And torso, AAPM and IEC phantom images were acquired with combination of 3 methods in condition of 120 kV, 25 mAs to evaluate radiation exposure, noise, spatial resolution and SUV changes. Results When applying AEC, CTDIvol and DLP were decreased by 50.52% and 50.62% compare to images which is not applying AEC. mAs was increased by 61.5% to compensate image quality according to decreasing 20 kV when applying CAREkV. However, CTDIvol and DLP were decreased by 6.2% and 5.5%. When reference mAs was the lower and strength was the higher, reduction of radiation exposure rate was the bigger. Mean SD and DLP were decreased by 2.2% and 38% when applying SAFIRE even though mAs was decreased by 37.5%(from 40 mAs to 25 mAs). Combination of 3 methods test, SD decreased by 5.17% and there was no significant differences in spatial resolution. And mean SD and DLP were decreased by 6.7% and 36.9% compare to 120 kV, 40 mAs with AEC. For SUV test, there was no statistical differences(P>0.05). Conclusion Combination of 3 methods shows dose reduction effect without degrading image quality and SUV changes. To reduce radiation exposure in PET/CT study, continuous effort is needed by optimizing various dose reduction methods.

Objectives : The purpose of this study is to establish a Korean medical perspective on the human body through understanding of the meridians according to the distribution of the three yin and three yang (삼음삼양) and the opening, closing and pivot (관합추) as defined in ≪Huangdi's Internal Classic≫. Methods : A total of 8 medical databases including KISS, Earticle, DBpia, RISS, OASIS, KMbase, and ScienceON were used to search studies published through July 2021, and literature was included without limitations on the publication period. The search terms were "(meridian OR acupoint OR meridian sinew) AND position" OR "Gwan-Hap-Chu" OR "Gae-Hap-Chu" OR "three yin and three yang". Two researchers independently made choices among the searched literature based on the preplanned selection/exclusion criteria. The search terms were"(meridian OR acupoint OR meridian sinew) AND position" OR "Gwan-Hap-Chu" OR "Gae-Hap-Chu" OR "three yin and three yang". Results : Of the 36 obtained from the survey, 19 (53%) followed the definitions of "internal diameter" for "three yin and three yang" and "the opening, closing and pivot," but 6 (about 16%) took a neutral position and 10 (22%) avoided mentioning. Therefore, it was judged that research was needed to end the debate on the distribution of 'three yin and three yang' and 'the opening, closing and pivot'. In order to apply the definition of ≪Huangdi's Internal Classic≫ on 'distribution of the three-yin and three-yang' and 'the opening, closing and pivot' to the upper limb and lower limb as well as the torso of the human body, this author proposed a human body model with both upper limb and lower limb attached, inspired by the posture of the fetus in the developmental stage. Conclusions : In this study, using a new human body model, it was revealed that the distribution of the three yin and three yang and the opening, closing and pivot' as defined in the ≪Huangdi's Internal Classic≫ can be applied not only to the torso of the human body, but also to the upper limb and lower limb. Based on the understanding of meridians, the selection of meridians in the clinical acupuncture should be made accurately, and continuous interest and research on this are expected.

According to several pilot tests, petite women have their own body proportion which is not simply an overall diminutive reflection of the proportion of Misses sizes. Apparel manufacturers and pattern companies do not consider racial differences nor do they consider petite women's own specific body proportions in their size categories to produce petite garments. The primary objectives of this study was to describe the petite women's body proportions especially the differences between Asian and Caucasian petite women and to compare their body proportions to the average body figure. A physical body measurement chart was developed and revised through a pretest. Sixty subjects, thirty for each group of Asian and Caucasian. They were landmarked using an anthropometric instrument and photographed using the method of somatography for analysis of body proportions. Data were analyzed by t-test for a description of the petite subject's body proportion. The results of this study indicated that the Caucasian subjects had generally a longer lower torso than tehAian subjects in their body proportions. both subject groups had differnt body proportions from the aerage body figure.

The purpose of this study was to determine the impact of demographics on body-cathexis and clothing expenditure of elderly men and women. Data were obtained from 50 men and 58 men and 58 women aged 55 years and older through an mail survey. Body-cathexis consisted of five areas of body parts: head/upper body, lower body, height, weight, and torso. Clothing expenditure was measured by the total dollar value of annual personal expenditures on personal apparel, including accessories, such as shoes, and clothing services. Demographics included income, age, education, sex, marital status, and social participation. Data were analyzed using multiple regression. The results showed that there were relationships between body-cathexis and four demographic variables(income, sex, education, and social participation). Elderly men were more satisfied with their bodies than were elderly women. The subjects with higher income, education, and social participation had a higher degree of body satisfaction. Also, there was a significant relationship between income and clothing expenditure.

The Denavit-Hartenberg symbolic notation provides the framework for the convenient and systematic method for the robot manipulator kinematics, but is limited its use to the lower pair mechanism or to the single loop mechanisms. The Sheth-Uicker notation is its revised and generalized version to be extended fur the entire domain of the link mechanism including the higher pairs. This paper proposes the method that uses the Sheth-Uicker notation fur the robot kinematics modeling. It uses the instantly coincident coordinate system and the closed loop chain fur the coordinate transformation. It enables us to model the velocity kinematics of the robot that has the complex structures such as the ternary links and the wheels in a systematic and rational way. As an implementation of the proposed method, the Jacobian matrices were obtained for not only the robot with two legs and a torso, but a manipulator on a mobile platform.

The purpose of the present research is to determine, for a sample of female college students, the effects of body-cathexis and importance of ideal body image on satisfaction with ready-to-wear. The sample included 177 female college students aged from 18 to 25. To measure the variables, an instrument was developed based on previous studies. Body-cathexis and importance of meeting the ideal body image were measured for five areas of body parts; head/upper body, lower body, height, weight, and torso. Satisfaction with ready-to-wear includes satisfaction with the fit at pant length, thighs, hips, waist, bust, and neckline, and with the variety in ready-to-wear. Research hypotheses were tested using multiple regression. The results showed that there was a positive impact of body-cathexis for a specific body area on ready-to-wear satisfaction which is related to the body area. The effect of importance of meeting the ideal body image on ready-to-wear clothing was different in regard to different areas of body parts.

In this study, the human gait trajectories during normal walking were synthesized using the inverse kinematics and optimization techniques. The synthesis based on a lower extremity model consisting of a torso and two legs. Each leg has three segments: thigh, shank, foot, and is assumed to move with six degrees-of-freedom. In order to synthesize trajectiories of this redundant system, the sum of angular displacements of articulating joints was selected as an objective function to be minimized. The proposed algorithm in this study is very useful for the analysis of human gait. For the gait analysis, the trajectories of four points in each leg should be measured. However, by using the algorithm, measuring the trajectories of two points is sufficient, and thus the experimental set-up can be simplified. The predicted joint trajectories showed a good agreement with those obtained from the experiment. The statistical analysis and graphic simula- tions are also presented.
