Objective: The purpose of this study is to develop an all- in-one collar shirt with excellent appearance which is well suited to the body shape of the male adults. Background: As men's casual wear has recently become more casual and the number of cool biz wearing in the summer has increased, a variety of shirt colors have been preferred in addition to shirt collar. However, studies on the design and pattern development of men's casual shirt collars are very rare. So we have identified the necessity of various development and research of men's shirts. Method: We collected 8 all-in-one collar patterns for shirts from professional pattern books and men's shirt brands. Also, based on anthropometric data from the 6th Size Korea, we selected 5 subjects with measurements similar to the average adult men, manufactured shirts based on them and conducted a wearing test by 5 experts. Results: After selecting shirts with good fit and appearance, we developed a prototype of all-in-one collar. As for front appearance evaluation, E1 pattern had the most outstanding shape and size, and C1 pattern had the most natural creases and front adjustment curves. As for side appearance evaluation, C1 had the highest overall scores, and E1 pattern on outer line. As for back appearance evaluation, C1 pattern had the highest score. Conclusion: We suggested new all-in-one collar and shirt patterns. In addition, the prototype of the all-in-one collar shirt design was presented by reflecting results of the wearing test and preference survey. Application: The shirt's design and patterns could be manufactured using the developed patterns. It will fit well with the body shape of adult males and will be highly satisfied by them.

This study aimed to develop a fitted torso pattern with an improved fit for inverted-triangular males in their twenties. For this study, six torso patterns were collected, compared and evaluated, and a fitted torso pattern was developed using virtual fittings. The research results are as follows. First, the fitted torso pattern received a good rating as a result of the virtual fitting evaluation: waist dart set 2 of the front; the amount of comfort is set at 5 cm around the chest, 4 cm around the waist and 10 cm around the hips. Second, the evaluation of virtual fitting of the development pattern showed that fit evaluation was 4.11/5 points, ease evaluation was 6.53/7 points, and that the stress map and airgap were suitable for the human body. Third, the actual fit evaluation of the development pattern was 4.25/5 points, 6.35/7 points for ease evaluation, and 4.81/5 points for motion evaluation. Fourth, there was no significant difference between the results of the virtual and actual fitting evaluation with the objectivity test. It is therefore possible to apply a pattern developed through a virtual fitting to an actual human body and to confirm the objectivity of the pattern.

The objective of the current investigation is to establish techniques in micro pattern forming operations of polymeric circular tubes by using hydrostatic pressing. This method was developed and successfully applied to the micro pattern forming on polymeric plates. The key idea of the new technique is to pressurize multiple vacuum-packed substrate-mold stacks above the glass transition temperature of the polymeric substrates. The new process is thought to be a promising micro-pattern fabrication technique for two reasons; first, (hydro-) isostatic pressing ensures a uniform micro-pattern replicating condition regardless of the substrate area and thickness. Second, multiple curved substrates can be patterned at the same time. With the prototype forming machine for the new process, micro prismatic array patterns, 25um in height and 90 degrees in apex angle, were successfully made on the PMMA circular tubes with diameters of 5~40mm. These results show that this process can be also used in the micro pattern forming process on curved plates such as circular tube.

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.

This paper presents a lip print recognition by the pattern kernels for a personal identification. A lip print recognition is developed less than the other physical attributes of a fingerprint, a voice pattern, a retinal blood/vessel pattern, or a facial recognition. A new method is proposed to recognize a lip print bi the pattern kernels. The pattern kernels are a function consisted of some local lip print pattern masks. This function converts the information on a lip print into the digital data. The recognition in the multi-resolution system is more reliable than recognition in the single-resolution system. The results show that the proposed algorithm by the multi-resolution architecture can be efficiently realized.

The developed patterns by direct writing of electron beam are measured by AFM, FESEM and optical profiler of WYKO NT3300. From different measurement methods, the measured linewidths of the patterns are shown a little bit wider than designed pattern size due to electrons scattering effect during direct writing of electron beam. The optimized conditions of these experiments are suggested and explained for the forming of structures below 0.1 ㎛ dimension size. Because of electron scattering effects from the different under layers such as Si, Si$_3$N$_4$ and aluminum, the developed pattern size is also influenced by the accelerated energy of electrons, dose, resist and soft and hard bake conditions in PMMA. The distributions of electron beam and calculations of backscattering coefficient are demonstrated by Monte Carlo simulation. From the measured results, the developed linewidth of PMMA/Al /silicon is shown a little bit wider than that of PMMA/Si$_3$N$_4$/silicon structure due to the backscattering effects.

The purpose of this study is to design high school boy's uniforms, which fit well and express the traditional aesthetics of Korean clothing. Korean traditional clothing is getting ground for the use as active wear as well as formal wear such as wedding or special holiday clothing. This is partly due to the introduction of western clothing in Korea because of the practical nature of this type of clothing. This study was carried out as follows: 1. First, 197 high school boys from 5 different high schools were surveyed. All of these schools use Korean style school uniforms. The survey asked the students about their satisfaction with the current designs, problems and design preferences for Korean style high school uniforms. In general, the boys are not satisfied with the aesthetic and fashionable aspects of their uniforms. 2. The second survey dealt with design preferences from a variety of design options of Korean-style school uniforms. The design options were presented to the students as in the form of 10 different types jackets and 6 different types of pants. Using the results of the second survey as a guideline, the designs of Korean style school uniforms were developed. 3. In order to make the test garments, a block bodice pattern for the Korean style school uniforms was developed. Using the developed bodice block pattern, 6 designs were made of wool. The 6 test designs consisted of 3 different types of jackets and 3 different types of pants. 4. Incorporating the most preferred design features, school boy Korean style school uniform designs were developed. The characteristics of the design include neck line opening and its finishing, AH and sleeve shape, embroidered traditional patterns and fastenings. In this study we were able to develop comfortable clothing, which expressed the traditional aesthetics of Korean clothing.

The purpose of this study was to develop a new torso pattern for the schoolgirl of a tween generation who had different somatotype from children and teenagers. The subjects in this study were female elementary school students of fifth or sixth grade. Through a sensory evaluation of four existing torso patterns, the first research torso pattern was developed. Drafting methods of each item, which closed to the optimum value three, were selected. The differences between the values of the selected drafting methods and the optimum three were verified through a Wilcoxon's ranked sum test. The final research torso pattern was developed through adjusting the drafting methods according to the deviation from the optimum value three. The schoolgirl of a tween generation is at the time to show the remarkable breast development compared with a waist circumference, so the bust drafting was defined as B/4+ 1.25cm separately front and back. The drafting of a waist circumference was defined as W/4+1cm separately front and back which taken the ease amounts of the somatotype into consideration of the schoolgirl of a tween generation. A princess line was used instead of a waist dart because their hip circumference was more developed than a waist circumference. The crossed amount of a front hemline was 0.3cm and that of a back hemline was 0.7cm. and the princess line of the position was drawn with a straight line at a right angle of the back waistline. The armhole depth was determined B/4-1cm in consideration of the aesthetic and the trend, although the effective movement of upper arm was required.
