The purpose of this research is to define low body shapes of Plus-sized women at ages between 21 and 69 whose satisfied the Plus-sized judgment criteria took part in this study. This research also classifies different body types, and provides basic data for designing skirt's and slacks' prototypes according to each body type. Based on factor analysis of the measured data, seven key factors are grouped. And four different body types are classified based on the cluster analysis using factor marks. Type 1 refers to those who are tall in stature and balanced. This body type is characterized by trapezoid body shape when looked from the front, and slim the abdomen, bulge the belly and flat the buttocks when looked from the side. Type 2 refers to short and an obese body shapes, with trapezoid front and bulge abdomen and belly and flat the buttocks. Type 3 refers to those who are of medium height and long-legged body shapes, with rectangular front, protruding belly and buttocks. Type 4 refers to obese body shapes, with rectangular front, protruding abdomen and belly, flat the buttocks. 9 items are available to judge Plus-sized women's low body types and the hit ratio is 93.5%.

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.

The purpose of this study was to apply the three dimensional Replica method to the fabrication of dress forms of plus-sized women to attain proper ease through draping and based on the ease to develop good torso patterns with superior fit. The results were as follows. The physical characteristics of the dress forms of plus-sized women were divided into two: Types I and 11. The proper ease was calculated through draping using dummies of each somatotype and appropriate torso patterns were developed. The differences of the types for each pattern were as follows. The bust girth ease of Type II was 6cm as for Type I. As for the bust breadth 1.0cm was added to the anterior chest width, the armpit width was the actual measurement plus 0.5cm, and the back breadth was the posterior chest width plus 2.5cm. The bust breadth was smaller and the back breadth was bigger that those of Type I after improving the bust and back fit. The bust of Type I protrudes outwards relatively and so the shoulder dart of front-side of Type I was 1.2cm bigger than that of Type II which improved the bust region fit. Considering the characteristics of the protruding abdominal region the front- side waistline of type II was assigned W/4+3.5cm and the back-side waistline W/4cm, so that the sidelines divided the front and back properly. It was drafted so that the center-front became diagonal, thereby improving the middle-hip girth fit.

The purpose of this study was to develop a new basic skirt pattern for 4 lower body types of Plus-sized women. To reduce a time and economic loss about putting it on, This study applied a 3D sample module in the course to develop a basic skirt pattern which is fit, functional and beautiful. A data analysis used the SPSS 11.0 statistics program. To verify the difference, This study used the variance analysis and Duncan's test for the postmortem verification. The result was as follows. To reflect a feature according to an abdomen projection and hip projection, we added the maximum hip circumference to the waist circumference and hip circumference for necessary for a skirt draft item. The front hip circumference sets to the H/4+1cm(ease)+D/4. The back hip circumference set to the H/4+0.5cm(ease)+D/4. The D is the hip circumference in the maximum hip circumference to subtract. The front waist circumference sets to the W/4+0.5cm(ease)+0.5cm(A front and back's difference)+D/4. The back waist circumference sets to the W/4+0.5cm(ease)-0.5cm(A front and back's difference)-D/4. Compare with 4 lower body types of Plus-sized Women, A type 2 and type 4 abdomen projections are bigger. We raised a front waistline of skirt pattern to a 0.3cm upside, and take about 1.3cm down the skirt length from a developed skirt pattern. Consequently, the appearance of a front skirt length was improved with a side skirt length.

The purpose of this study was to recognize of the sizing system and analyze the fitting on formal pants of the on-line shopping mall for plus-sized women. To pursue this purpose, the investigation of the sizing system was focused on 22 online companies. The formal pants of 7 companies was selected among them. And actual sizes were compared with the guidance sizes of goods. For the assessment about the fitting on formal pants of 7 online companies, these came to make on to 16 obese women with 'A' body shaped and 'O' body shaped. A data analysis used the SPSS 14.0 statistics program. To verify the difference, this study used the variance analysis and Duncan's test for the postmortem verification. The result was as follows. 1. All of 22 companies were using the symbol such as 88, 99, 100 and 110 in the present condition of sizing system. The information about products size was presenting the products size not to be the body size. the guidance sizes of products were different from actual sizes of 7 companies to be assorted. Therefore, the guidance sizes of goods could not accomplish the facility. 2. According to the fitting-tests by the sensory assessment, the obese women with 'A' body shaped, did the dissatisfaction at the items of the hip circumference, abdominal region, crotch deep and pants length. The obese women with 'O' body shaped, did the dissatisfaction at the the items of crotch deep and pants length.

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 this study was to investigate current garment sizes of women's formal jackets, targeting plus-size women in online shopping malls, and to identify effective size information involved in online apparel purchase behaviors to overcome the short comings of current garment sizes from the perspectives of consumers. Basic 88 size formal jackets from the seven companies found on the 22 websites were collected and analyzed. The data were collected from March to October 2007, and analyzed using SPSS 14.0. The results were summarized as follows. First, there was no website using standard garment size labeling with 'bust-hip-height' set up by KS K 0051 among the 22 websites. Instead, all 22 websites used garment size labeling with figures such as 88, 99, 100, 110, and 120 or with letters such as L, XL, and XXL. The websites presented no body size, but listed garment size. Furthermore, the size information was presented differently, ranging from three items of bust circumference, upper arm length, and jacket length to six items of shoulder width, bust circumference, waist circumference, sleeve width, sleeve length, and jacket length. In addition, no website presented basic information for hip circumference, despite the jacket length covering the hips. Second, a total of 85.7% the websites listed bust circumferences in 88 garment sizes collected as 100cm. Shoulder widths were presented as 39cm or 37cm. Sleeve circumferences were addressed the same, 36cm, in all websites. Third, comparing the differences between guidance sizes and measurement sizes, only 28.5% of the web sites posted guidance sizes of shoulder widths the same as those of the measurement sizes. All web sites presented guidance sizes of bust circumstances as 1 to 5cm smaller than those of the measurement sizes.

Community composition and functional feeding groups of aquatic insects according to stream order were investigated from the Gapyeong Creek, a typical mid-sized Korean stream in Gyeonggi -do, Korea, in April 2000. For field investigations, the main watercourse and three major tributaries of the stream that belong to stream order ll to Vll were divided into reaches (ca. $1{\sim}4$ km in distance). Aquatic insects were sampled from one or two sites each reach (total 30 sites) using a Surber sampler ($50{\times}50$cm, mesh 0.75 mm). As a result of the quantitative samplings(two Surber samplings at riffle and pool/run per site; total $2{\times}30$=60 Surber samplings) and additional qualitative samplings, a total of 164 species of aquatic insects in 103 genera, 54 families, and 8 orders were collected from the stream. Those aquatic insects were composed of Trichoptera (56spp.: 34.1%), Ephemeroptera (43 spp.: 26.2%), Diptera (25spp.: 15.2%), Plecoptera (23 spp.: 14.0%), Coleoptera (6 spp.: 3.7%), Odonata (6 spp.:3.7%), Hemiptera (3 spp.: 1.8%), and Megaloptera (2 spp.: 1.2%); EPT-group (122 spp.:74.4%) or EPT-group plus Diptera (147 spp.: 89.6%) occupied most of the aquatic insect community; relatively larger number of species occurred in the mid-stream reaches (order III-Vl). The quantitative samplings throughout the study sites yielded a total of 26,286 individuals of aquatic insects ($136{\sim}2522$ inds./0.5 $m^2$, mean 906.4inds./0.5 $m^2$) that belongs to Ephemeroptera (11,994 inds.: 45.6%), Diptera (8730 inds.:33.2%), Trichoptera (4123 inds.: 15.7%), Plecoptera (1213 inds.: 4.6%), Coleoptera (204 inds.: 0.8%), Odonata (13 inds.: 0.05%), Megaloptera (5 inds.: 0.02%), and Hemiptera (4inds.: inds.: 0.02%); average number of individuals of aquatic insects increased as the stream order increased: average numbers of individuals of Bllecoptera and Trichoptera decreased and increased, respectively, as the stream order increased. Tolerant species such as Chironomidae spp., Uracanthella rufa and Hydropsychidae spp. were particularly abundant in the down stream reaches (order Vll) . Species diversity indices (H`) and dominance indices (Dl) were relatively higher and lower, respectively, in the mid-stream reaches (order $IV{\sim}VI$). Shredders occupied the smallest partand collector-gatherers were most abundant among the functional feeding groups(FFGs); collector-filterers considerably increased in the down stream reaches (orders Vl and VII); scrappers were relatively evenly distributed throughout the stream reaches: predators were relatively more abundant in the uppermost stream reaches(order ll) . Overall, the characteristics of aquatic insect comminity and FFGs in the Gapyeong Creek are largely similar to those in the normal streams of temperate deciduous forest in the northern hemisphere that is explained by the river confineum concept.
