The aim of this research is to model the three-dimensional shape of clothes worn for easy customization of ready-made clothes. We investigated the method for modeling bodice parts of clothes worn as a first step. The three-dimensional human body shape data of 55 Japanese adult women (22-55 years old) were analyzed. The data of the trunk from neckline to waistline was chosen from three-dimensional human body shape data, and convex hulls of these data were generated. A homology model of the convex hulls was generated based on landmarks. A bodice model was generated by the homology model of the convex hulls converted into bilaterally symmetrical shapes. As a result of analyzing 55 bodice models by principal component analysis, the characteristics of bodice shapes were explained using five factors: slender or stocky build; body thickness; shoulder slope and posture (sloping shoulders with stooped body vs. square shoulders with backward-inclined body); breast size and the inclination from a bust line to a waist line; and positional relationship between the humerus head to the trunk. These are important factors for fitting of clothes. The result shows that we can model the bodice part of clothes worn by adjusting the mesh of the bodice model to the grainline of fabric.
Objective of this study was to clarify acute influence of boxing exercise (BE) and Yoga on psychological state in middle aged women. The subjects were 40 middle aged women (20 in each program) who voluntarily participated in either class of BE program or Yoga program provided in local community. Psychological state was assessed using Profile of Mood States (POMS), composed of 6 subscales (Tension-Anxiety, Depression-Dejection, Anger-Hostility, Vigor, Fatigue, Confusion), before and after the class. The acute influence on the mood of each exercise program was examined by within group comparison of change using Wilcoxon test. Difference of change in the mood between the groups was examined by analysis of covariance using the change in the mood from before to after the class for the objective variable, groups for explanatory variable, and a value of mood before the class, age, and BMI for adjusting variables. As a result, the BE group showed significant positive within-group differences in the subscale of “Tension-Anxiety” and “Depression”. The Yoga group showed significant positive changes in “Tension-Anxiety”, “Depression”, “Anger-Hostility”, “Vigor”, and “Confusion”. The significant difference of change in the mood between the groups was observed in the subscale of “Anger-Hostility”, which showed negative change in the BE group and positive change in the Yoga group. These results showed that the BE and Yoga programs, composed of different mode (dynamic or static) of exercise, brought an acute changes in the mood in the middle-aged women, but that the pattern of the change in profile of the mood was different by the mode and intensity of the exercise program.
Recent interest was forced on non-alcoholic fatty liver disease (NAFLD) related to the metabolic syndrome. The prevalence of NAFLD in Japan is increasing and estimated as about 30%. Branched chain amino acids (BCAA) has been reported to promote skeletal muscle synthesis, and suppressive effects of organ lipid accumulation has been also reported. The aim of this study is to estimate the effects of BCAA on the liver lipid accumulation and proinflammation in diet-induce obesity mice. Five-week old male C57BL/6J mice fed a high fat diet (50 energy % by lard) and test diet containing 20% casein (CO as control), 12% leucine and 5% valine mixture (LV) for 12 weeks. Liver triglyceride accumulation was significantly decreased in the LV group. Significant differences between CO and LV group were not observed in mRNA expression of TNF-alpha and a subunit of the NADPH oxidase enzyme, which is proinflammatory markers, and lipid metabolism-related enzymes were not observed. Acyl-CoA oxidase (ACOX) activity was significantly higher in the LV group compared with the CO group, whereas the activity of FAS was not significantly different. These results suggest that leucine and valine suppresses liver lipid accumulation through the activate in of the ACOX.
