Based on instructions in the textbook "How to Construct Korean Costumes" which I authored, my university students were required to make Pungcha-Baji(Korean traditional pants for children) for one-year-old boys. While examining the students' construction, I found that the side seams of the vest and pants did not line up but were improperly twisted. It was found that the pants did not cover the child's backside because the width of the back was smaller than the width of the front when one of the side panels and the large center panel in the front was half the size of the hip and one of the side panels and the small panel in the back was four fifths of half the size of the hip. Although there were differences between the waist size of the pants and the bottom hem of the vest, the textbooks instruct that the amount of material and the number of pleats(i.e. 4 pleats) on the pants and the vest should be the same. Finding this mistake led me to investigate Pungcha-Baji construction in related textbooks. Thus with the textbook instruction, the side seams of the pants and the vest do not match and are improperly twisted. Hence, as a solution, the pleats should be made and adjusted after matching the side seams of the pants and the vest. The purpose of this study is to examine currently available Pungcha-Baji related textbooks and determine the correctness of their instructions and to ultimately provide correct construction methods for Pungcha-Baji pattern for academic purposes.

This study evaluates the difference in visual images according to changes in waist position and pants style. The researcher made twelve stimuli-combination of four pants styles (classic, baggy, skinny, bell-bottom) and three waist positions (0cm, -3cm, -5cm). The test involved 48 female college students. The stimuli were made using the i-Designer computer program. The panels tested the screen images of all manikins wearing pants. A 7-point scale was used to evaluate each image. For the data analysis, the ANOVA and Duncan-test were applied along with an SPSS program. The results of this study are as follows. The visual evaluations by pants style and waist position are composed of seven factors (attractiveness, attention, hip, activity, height, waist, abdomen). Among these factors, attractiveness is evaluated to be the most important factor. The mutual agreement of the visual effect (according to pants style and waist position) was indicated as four factors of attractiveness, attention, waist, and abdomen. The height factor is evaluated to be the most important factor by change in regards to waist position. The 0cm waist position of three styles (classic, baggy, bell-bottom) were evaluated positively in elongated height whereas the -3cm, -5cm waist position of the skinny style was evaluated positively in elongated height. The mutual agreements of visual effect (according to pants style and waist position) were not indicated.

Unlike other processes such as washing, the ironing process in the laundry process is difficult to standardize and thus relies on manual labor. Unlike upper garments, pants have pleats at the waist as well as a crease line below the waist, Therefore, two separate ironing devices have been developed and used. However, in this method, problems such as additional worker input, space loss, and wrinkling of pants occur due to manual movement between processes, Consequently, a pants ironing device that combines the two equipments is required. The all-in-one pants ironing system described in this paper automatically sequentially irons the upper part and side of the pants regardless of the length, shape, and upper pleats of the pants. It also performs a self-diagnosis function while displaying the ironing progress on the user's monitor. As a result of this study, it became possible to double the amount of ironing and reduce power consumption by more than 20% compared to the case of using two independent equipment.

The purpose of this study was to compare and analyze the present condition of pants grading and the methods for the specific dimensional increments, a questionnaire has been conducted. For the questionnaire, 16 casual wear brands, which were on higher ranking of sales in Korea, were selected. The results are summarized as follows. Based on the pants grading data resulting from the research conducted on the (16) domestic clothing brands, the grading method could be classified into three different types. According to the criteria; i.e., the front and back divided by crease of pants and the deviation ratio of the grading increments of the waist and the hip girth, the grading types were (1) G1: front 5:5, back 5:5, (2) G2: front 4:6, back 4:6, and (3) G3: front 4:6, back 3:7.

A pair of pants $\sum(0,\;3)$ is a building block of oriented surfaces. The purpose of this paper is to determine the discrete conditions for the holonomy group $\pi$ of hyperbolic structure of a pair of pants. For this goal, we classify the relations between the locations of principal lines and entries of hyperbolic matrices in $\mathbf{PSL}(2,\;\mathbb{R})$. In the level of the matrix group $\mathbf{SL}(2,\;\mathbb{R})$, we will show that the signs of traces of hyperbolic elements playa very important role to determine the discreteness of holonomy group of a pair of pants.

It is remarkable that the children's wear market has been growing instead of declining birth rate. The parents are willing to pay more when they find children's wear of better design and improved quality. For better quality, it is necessary to research on the pattern making of children's wear. After the interview with the 10 leading children's brands, we found that they develop individual design pattern based on each items middle block pattern which characterize the brands design line. Most frequently used middle block is for casual pants. Through interview with pattern designers, comparative study of patterns drafting methods, wearing test of trial garments and altering and adjustment of patterns, we developed the casual pants block pattern for 7 years old boys.

As the digital environment gets ubiquitous, domestic and international research and development on smart clothing is being conducted actively these days. However, most research is being carried out with its center on upper garment. So research on lower garment is insufficient even though it affects wearer's activity and comfort to a great extent when digital devices are attached or wearers moves their body. Therefore, the type of clothes this research proposes is men's formal pants which have an electrically-vibrating wearable device. These are smart pants which are helpful in easing muscle pain with their massaging effect in daily life. For this purpose, this research intends to develop patterns considering the body shapes and movements of wearers and suggest a tentative structure plan for smart pants where a vibration device is attached, which is mainly composed of vibrating motor, controller, and switch, and considered their bulks, numbers, attaching places.

The dimensional structure of impression formed of a female figure in specific attire was identified and significant influence of skirt length and suit color on impression formed of figures in suits were researched in the part I of this study. In part ll, the effect of identical elements of apparel design on impression formation of a female figure in dress and pants- blouse were studied. The experimental matirals consisted of two sets of stimuli and 7 point semantic differential response scale developed in part 1. Each set of stimuli was composed of 20 drawings representing female figures in each attire. Three independent variables, which were the length of bottom, color of dress or pants and collar type of blouse, were manipulated in each stimulus. The experiment was arranged by 3 factorial design, and the data were analyzed by 3-way ANOVA and by Multiple Classification Analysis. To summarize, in impression formation of figure in dress, the most dominant design element was identified as bottom length and the second most dominant one was color of dress. In contrast, in perception of figure in pants-blouse, the most important design element was color of pants and secondly important one was bottom length. The collar type of top didn't have critical effect on impression formation of figures in both type of attire.

This study investigated the usage of child hospital gowns to suggest a gown design suitable for child inpatients in Korea. The satisfaction on size suitability and design of child hospital gowns was surveyed among 219 child inpatients in 20 general hospitals. The most hospitals provided 2 to 4 different size pajamas for child inpatients. However, 53% of the subjects chose not to wear the uniform pants that the hospital provided and 28% did not wear the shirts. The reasons most often given for rejecting to wear the uniforms were unsuitable size (42.1%) and difficulty in taking on and off (26.2%). The dissatisfactory parts of hospital gowns were pants length (27.9%), sleeve length (19.6%), pants waist closure (16.9%), and neckline opening (11.9%). The preference in gown design for child inpatients varied by age (p〈0.5) and the styles that they had worn (p〈0.5). Significant differences for style preference were found in the opening of shirts or pants, pants waist closure type, and pants length. These results suggest that the hospital gowns for child inpatients need to reflect the wide diversity in their body size and preference in style.

This study aims to develop the functional pants for the hospitalized bed-ridden patient. The procedure of this study consisted of three parts. First, the interview survey of nursing care givers was conducted to inquire into the conditions of bed-ridden patients' clothing. Second, the bed-ridden patients' pants design and sample making were accompanied. Then, the wearing tests and design development were completed. The results are as follows; The conditions of bed-ridden patients' clothing were the convenience of clothing change, the partial opening for diaper change and medical treatment and the ventilation for bedsore prevention. The design development of the bed ridden patients' pants was accomplished which had the side seams with two way opening zippers, the wraparound pattern of abdomen and the opening under crotch applied the advantage of korean traditional underwear sokkot. The samples' wearing tests were performed three times and those subjects were the hospitalized bed-ridden patients. Consequently, we suggested the appropriate hospitalized patients' pants for bed-ridden patient.
