The contents of clothing and textiles area of elementary home economics textbooks from 1948 to 1955 were investigated. Home economics of elementary school education in those days corresponds to practice acts of elementary school education in present. Practical acts has the all-around concepts of the agriculture, industry and home economics Also the knowledge or skill for actual life are teamed. Practical acts education was started from lessons of sewing for women under title of 'jaebong'. It can be said that practical acts education was started from clothing and textiles area. The home economics elementary textbooks of the year 1948 were composed of 21 units for 5th grade and 22 units for 6th grade. The textbook for 5th grade of 1953 was composed of 19 units, and one for 6th grade of 1955 was composed of 18 units. The clothing and textiles area accounts for 38.6% in 5th grade textbook, for 32% in 6th grade textbook of 1948 and for 31% in 5th grade of 1953 and 6th grade textbooks of 1955. The textbook contents of clothing and textiles area were classified into five fields of sewing, knitting. patching, embroidering and care. In 1948, textbooks were placed a great deal of weight on sewing field education as 7 units of 15 units. The 7 units for sewing fields have suitable connection to develop. But, in the case of knitting, patching or care, just groundwork of each field was included for application to actual life without vertical connection. The contents of textbooks for clothing and textiles area in 1953 and 1955 were much alike with those in 1948.

This research was conducted to provide basic data to improve expressivity required for virtual clothing to replace actual clothing. For the experiment, 6 materials were selected and 12(2 kinds of length) actual flared skirts were made. At the same time, simulations were carried out on OptiTex Runway 12.0 for 36(12 kinds of skirts $\times$ KES, FTU, KES weight/10) kinds of virtual flared skirts, which were applied with the measured property values (thickness, weight, bending, shear, friction, and stretch). Also, the study compared and analyzed the wearing images, silhouette overlapping images, and skirt length measurements of the actual and virtual skirts put on a dummy. As a result, the actual skirts showed clear distinction for each material. In contrast, virtual 1 and 2 expressed fabric 3 in the most similar way, but could not recreate the uniform, soft, and natural flare shape of the actual skirts in general. Virtual 3 formed natural flares as those of the actual skirts, and expressed fabric 1, 5, and 6 in a similar way. However, virtual 3 had too much volume and barely showed any distinction for each material. All of virtual 1, 2, and 3 expressed different flare shapes on the front and back sides of the skirt similarly to the actual skirts, and had a good visual expression for the color and texture of the materials. However, they could not effectively express the elasticity and fabric sagging in the bias direction.

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.

This study examined the effect of surfactant pretreatment on the pectinase-treated cotton/chitosan blends by weight loss and properties such as water absorbency, dyeability, tensile strength, pilling property, and surface morphology. The weight loss of cotton/chitosan blends was 1.5% by the surfactant pretreatment/pectinase treatment. The water absorbency and dyeability of samples showed a significant improvement by the surfactant pretreatment/pectinase treatment. The tensile strength and pilling property of treated fabrics showed no change. The water absorbency and dyeability of pectinase treated samples improved with the pretreatment of the surfactant without damaging the fibers.

This study provides the optimum papain treatment method and its effect on wool/polyester blend fabrics. The enzymatic treatment condition is optimized depending on its pH level, temperature, concentration of enzyme, treatment time and concentration of activators. The characteristics of samples treated with the papain are measured using weight loss, tensile strength, whiteness, WCA, dyeing property and surface micrographs. The results are described as follows: According to measuring weight loss, tensile strength and whiteness, a pH level of 7.5, $70^{\circ}C$, 10% papain(o.w.f.) and 60minutes of treatment time are optimized for papain treatment. L-cysteine and sodium sulfite are able to activate the papain. The optimum concentrations of them are 10mM and 50mM respectively. The WCA of fabrics is decreased since papain treatment makes wool/polyester blend fabrics more hydrophilic. Scouring with papain treatment improves whiteness and dyeing property of fabrics. The dyeing property of papain-treated fabrics is enhanced simply by a single step dyeing process using a basic dye. The surface of wool treated with papain in the presence of L-cysteine shows to be descaled. The surface of wool fibers in the presence of sodium sulfite, however, shows it is hydrolyzed evenly instead of being descaled. The surface of papain treated polyester fibers shows cracks and voids.

The purpose of this study is to check color change, color fastness, increase wt., antibiosis, and UV-protection efficiency depending on gallnut concentrations and mordanting methods, when silk fabrics dye with gromwell according to pH. This results will contribute in developing of natural mordant with multi function. The results are as follows. ${\lambda}_{max}$ of Gallnut extracts was near 299 nm. When gallnut was used as a mordant, at all pH levels, pre-mordanted fabrics had red color and post-mordanted ones had red-purple color which was closed to natural color of gromwell. Brightness of post-mordanted fabrics was higher than that of pre-mordanted fabrics. In the case of chroma, pre-mordanted fabrics was higher than post-mordanted fabrics. There was no significant difference of color, brightness, and chroma depending on gallnut concentration. As mordanting concentration increased, fabric weight gradually went up and increase weight reached maximum $17{\sim}19%$. At all pH levels, color fastness improved by pre-mordanting and post-mordanting, and it showed the maximum $4{\sim}5$ grade of wet fastness and 5 grade of dry cleaning. Antibiosis of silk fabric was improved by gromwell dyeing and synthetic tannin mordanting. Antibiosis of gallnut extracts was excellent. The color fastness and antibiosis were preserved after 10 cycle dry cleaning. UV-protection efficiency was excellent by dyeing with gromwell and mordanting with gallnut.

This study was conducted to offer basic data that can be used in a clothing industry for active senior males that are emerging as a new consumer bracket in a rapid aging age. To this end, this study conducted an analysis of 'younger' older male body types based on data from the 6th Size Korea. As a result of the body type analysis of 'younger' older males who are considered active seniors in comparison to 'middle' aged males, the former's height items became shorter compared to 'middle' aged males, but circumference items were bigger. Males aged 35-69, who are 'middle' aged males and 'younger' old males were divided into three body types in this study: Type1- small body type with protruded belly, compared to weight. Type 2- body type of slim torso with wide shoulder-back widths. Type3- big body type overall with tall height and heavy weight. According to body type distribution by age group, the middle-aged males had Type2 body type the most. The younger-old males showed type1 the most. There is a need to reflect the body types of active senior male characteristics in apparel pattern design because the current fits are not appropriate if active senior males wear clothing targeted for males aged 30-50.

This study was conducted to develop a comprehensive program for improving obese children's living habits such as wearing clothing and eating, and their self-esteem. Thirteen obese elementary school children, six boys and seven girls in the 4th to 6th grade, voluntarily participated in a ten-week intervention program. During the program, the obese children filled out a checklist consisted of daily ambient temperature inside the house, weight of clothing, meal diary, time taken for physical exercise, time taken for watching TV, etc. After carrying out the program, its effect was testified and evaluated. Percent body fat of the children measured using a body composition analyzer was reduced by $1.9\%$ after the program (p<.01). Wearing behavior of clothing was positively changed in view of the high correlation between ambient temperature and clothing weight (r=-.917, p<.01). Ability of dietary self control was improved and eating time was lengthened. Self-esteem was improved in global self-worth, athletic competence, and behavior/conduct. It was suggested that active interest of the family would be helpful and that an intervention program over longer than ten week would be necessary to improve childhood obesity.

This study investigates consumer awareness and concerns regarding apparel sizing in the realm of online shopping. A survey was conducted with 450 women aged 18-59 who had engaged in online clothing purchases within the past year. It was observed that consumers shop for clothes online an average of 1.6 times per month, with those under 50 shopping more frequently. The importance of size is higher when buying pants than jackets, especially in online shopping compared to offline purchases. Key references guiding online shopping decisions encompassed product sizing codes, customer reviews, and garment dimensions, which were notably favored by consumers with significant concerns. Respondents opted for Korean-style sizing codes for jackets but chose inch-sizing codes for pants. While awareness of height and weight remains high, knowledge of specific body measurements crucial for clothing size design is lacking, suggesting inadequate communication of size information. Respondents prioritized specific areas for jacket and pants fit, yet the lack of comprehensive self-measurements beyond height and weight might present challenges in determining fit based solely on product dimensions. To address this issue, online retailers should display essential garment dimensions and visually suggest clothing sizes according to various body types. These findings provide valuable insights for online retailers to effectively present size information and lay a foundational framework for consumer size education.
