This is a follow-up study to "An Analysis of the Fitting of Plus-sized Women's Formal Jackets in On-line Shopping Malls", in which we compiled basic sizes of formal jackets sold in online retailers for plus-sized women and compared specific measurements of the jackets from each retailer. Emphasizing a comparison of age groups 20-39 and 40-59, fit evaluations and analyses were conducted in order to provide data to help manufacturers develop formal jacket patterns that reflect physical characteristics of plus-sized consumers and offer better physical fit. The surveys and evaluations were conducted between October 2007 and May 2008. and the compiled data were analyzed using the SPSS 17.0 statistics program. The results were summarized as follows. The two age groups gave different evaluations of the fit problems in the women's formal jackets sold in online retailers. Whereas the age group 20-39 felt that the main problems were in the shoulder, armscye, upper arm, waist, abdomen and hip areas, the age group 40-59 said that they found more problems in the armscye, upper arms, sleeve length and jacket length. Modifying the shoulder area, armscye depth and jacket length severely compromises the jacket's balance, and attention to these areas must be given during pattern design.

Statement of problem. There have been few studies about the marginal fit of Auro Galvano Crowns. Purpose. The purpose of this study was to compare the marginal fit of the anterior single restorations. Material and methods. The in vitro marginal discrepancies of metal-ceramic, Auro Galvano Crown and coping were evaluated and compared. The Auro Gavano Crowns were made from one extracted maxillary central incisor prepared by milling machine. 30crowns per each system were fabricated. Measurements of a crown were recorded at 50 points that were randomly selected for marginal gap evaluation. Parametric statistical analysis was performed for the results. Results. Mean marginal gap dimensions and standard deviations at the marginal opening for the anterior single crowns were $74{\pm}21{\mu}m$ for the control (metal-ceramic restoration), $45{\pm}11{\mu}m$ for Auro Galvano Crown coping, and $51{\pm}9{\mu}m$ for the Auro Galvano Crown. Conclusions. Auro Calvano Crown showed significantly smaller (P<.05) marginal gap than the control. Ceramic application did not significantly affected the marginal fit of Auro Galvano Crown. (P>.05)

For fit satisfaction evaluation, the subjects were asked to put on the jackets from the seven manufacturers in random order, view how the jackets fit in a full-body mirror and answer questions regarding fitting in 22 specific areas, including the neck, shoulders, waist, hips and arms, as well as eight questions related to maneuverability. The surveys and evaluations were conducted between October 2007 and November 2008, and the compiled data were analyzed using the SPSS 14.0 statistics program. The One-way analysis of variance was performed to comparatively analyze the differences among the products from the seven manufacturers. Post-hoc tests were performed based on Duncan's test for the criteria that displayed significant differences. The results were summarized as follows. Fit evaluations were performed for the size 88 formal jackets from the seven manufacturers. All items, except the center front line, displayed significant differences at p<0.05 or higher among the manufacturers. The age group 20-39 felt that the main problems were in the shoulder, armscye, upper arm, waist, abdomen and hip areas. Modifying the shoulder area, armscye depth and hip areas severely compromises the jacket's balance, and attention to these areas must be given developed pattern design.

The purpose of the study is to analyze the suitability of ready-to-wear apparels for adult women by considering their body types. 341 women aged from 20 to 60 were surveyed for this study. The survey was taken from November, 1999 through November, 2000. The subjects were classified into 4 groups(thin, normal young aged, normal middle aged, fat) according to BMI and Rohrer index. For data analysis, descriptive statistics, crosstabs, F-test, Duncan-test were used. As the result, it is our findings that, in purchasing clothes, especially in case of pants, people choose them mostly based on waist and hip. However, in that the normal young aged group bases thigh circumference, we need to consider such points. As for one-piece, height was an important factor, while chest was the most important factor for the fat group. In relation to the suitability of ready-to-wear garments, the groups showed significant differences for blouses, one-pieces, and jackets, respectively. Blouses didn't fit 29.8% of the fat group, and one pieces fitted thin or normal subjects to some extent. However, one pieces didn't fit 34% of the fat group while jackets didn't fit 51.4% of them. This result shows that there are difficulties in choosing clothes dependent on body types.

This study collected the basic data required to develop a slim-fit jeans pattern for upper grade elementary school girls. First, a fit evaluation was made by selecting five slim-fit jeans of ready-to-wear brands. Subjects were four girls aged 11-12 with an average body size that evaluated the appearance and motion functionality of five brands of jeans. Five experts also evaluated their appearance. Second, pattern sizes were analyzed and compared with the average size of upper grade elementary school girls by measuring the pattern sizes of five brands jeans. As a result, Brand A received a high score in appearance and motion functionality. Brand E scored high with Brand A in appearance, while Brand E had the lowest score in motion functionality. For most of the five brand jeans, (+) ease was added to include a wide range of body sizes for upper grade elementary school girls, but the hip circumference, thigh circumference, and knee circumference of Brand E jeans were smaller than the average size of girls. The (-) ease was applied to make the figure look slim, which resulted in a high appearance score. However, since Brand E received a low score in the motion functionality, it could be seen that the (-) ease was not suitable for subjects although the material was stretchable. The result of this study will be used to develop a slim-fit jeans pattern suitable for upper grade elementary school girls.

This study investigates how bioecological variables affect the child's multiple intelligence through independent and interactional ways. The subjects of this study were 147 pairs of 5-year-old children and their mothers, and the Project Spectrum was employed to measure multiple intelligences. Each mothers was asked to answer a questionnaire on her child's temperament, her maternal parenting style, 'goodness of fit' and 'the fit of child's intelligence'. Data were analyzed using a factor analysis and a hierarchical multiple regression with SPSS WIN 15.0. The main findings were as followings; First, 'the goodness of fit' to the child's temperament moderated the effect of a maternal parenting style that would foster child's dependency on the mathematical intelligence through interaction. 'The fit of child's intelligence' also moderated the effect of maternal positive parenting style to the child's mathematical intelligence. Second, in language intelligence, girls were more verbally intelligent than boys. In that regard, because the sex variable entails a combination of both inherent attribute and social-cultural effects, that result can be interpreted as an interaction between the individual and the environment. Lastly, a maternal parenting style that would foster child's dependency moderated the effect of the child's regular temperament on interpersonal intelligence. This means that the child's regular temperament can be a protective factor for the negative effect of a maternal parenting style that would foster child's dependency This study suggests that interactional factors such as 'goodness of fit' should be considered in studies involving children.
