의류산업에서 대량생산에 비해 낮은 생산 효율로 인해 외면당했던 맞춤 생산이 새로운 첨단 자동화 기술과 IT 기술이 접목되면서 점차 실현 가능해지고 있다. 이에 본 연구에서는 소량으로 맞춤생산 되고 있는 야구복의 체형맞춤형 패턴자동화를 실현하기 위하여 체형변형룰과 패턴변형 알고리즘을 개발하였다. 연구 결과는 다음과 같다. 1. 체형맞춤의 사이즈를 커버하기 위한 첫 단계로 기준사이즈 패턴의 설계 및 선택을 위한 기준 사이즈 스펙으로 상의는 11개사이즈, 하의는 13개사이즈를 개발 하였다. 2. 체형변형요소를 추출하기 위해 야구복의 설계항목으로 요인분석을 실시하여 상의와 하의 각 4개의 체형변형요소가 추출되었다. 체형변형요소 중 착용방법과 디자인을 고려하여, 상의는 부피크기와 배돌출 정도(1요인)와 높이크기(3요인)를, 하의는 부피크기(1요인)와 높이크기(2요인), 밑위길이의 차이(3요인)를 패턴변형부위로 선정하였다. 3. 상의의 체형변형룰은 1요인인 부피크기요인은 기준패턴의 사이즈 선정에 적용하고 배돌출 정도는 기준패턴과의 차를 패턴 변형에 적용하였다. 3요인인 높이크기는 기준패턴과의 키 차를 패턴구간별로 비례에 맞도록 패턴 변형에 적용하였다. 4. 하의의 체형변형룰은 1요인인 부피크기는 기준패턴의 사이즈 선정에 적용하고 2요인인 높이크기는 기준패턴과의 키 차를 패턴구간별로 비례에 맞도록 적용하였다. 3요인인 밑위길이의 차이는 키와 배꼽수준허리둘레를 독립변수로 다중회귀식을 이용하여 패턴 변형에 적용하였다. 5. 이상과 같이 개발된 결과를 바탕으로 패턴탐색변수로 기준 사이즈패턴을 선정하고 기준사이즈와의 차이 치수를 체형변형룰에 의해 패턴변형을 실시하여 최종 개인의 체형맞춤형 야구복 패턴자동화가 가능한 체형맞춤형 알고리즘을 개발하였다. In the apparel industry, custom-made production, which had been neglected due to remarkably lower efficiency of production than that of mass production, has become increasingly practical by virtue of combination with new high-tech automation technology and IT technology in recent years. In this context, the present study was attempted to develop a body shape alteration rules and an algorithm of pattern alteration in order to realize the automation of baseball uniform patterns customized according to body shapes. The results of the study are summarized as follows: 1. As the first step for covering the sizes customized according to body shapes, standard reference sized patterns were designed and selected. For standard reference sized specifications, eleven (11) sizes for jerseys/jackets and thirteen (13) sizes for pants were developed. 2. To extract body shape alteration elements, a factor analysis was performed with the design parameters of baseball uniform. Four body shape alteration elements for each of jerseys/jackets and pants were extracted. In consideration for wearing method and design among the body shape alteration elements extracted, volumetric size and the degree of abdominal protrusion (Factor 1), and height size (Factor 3) for jerseys/jackets and volumetric size (Factor 1), and height size (Factor 2) and difference in crotch length (Factor 3) for pants were chosen as the regions of pattern transformation. 3. In the case of the body shape alteration rules for jerseys/jackets, volumetric size as Factor 1 was applied to sizing for standard reference patterns, while for the degree of abdominal protrusion, the difference from standard reference patterns was applied to pattern transformation. For height size as Factor 3, the difference in body height from standard reference patterns was applied to pattern alteration so that it could be proportionally suited by pattern intervals. 4. In the case of the body shape alteration rules for pants, volumetric size as Factor 1 was applied to sizing for standard reference patterns, and for height size as Factor 2, the difference in body height from standard reference patterns was applied to pattern alteration so that it could be proportionally suited by pattern intervals. As Factor 3, difference in crotch length was applied to pattern alteration using multiple regression analysis with body height and waist circumference(omphalion) as independent variables. 5. Based upon the above-mentioned results, standard reference sized patterns were selected as patterns exploring variables, and sizes with differences from standard reference sizes were adapted to pattern alteration through a body shape alteration rule, followed by developing an automation algorithm of custom patterns for baseball uniforms customized according to individual body shapes.

노년여성의 연령에 따른 체형특성과 라이프스타일을 고려하여 50대를 중심으로 한 액티브시니어 여성과 60대를 중심으로 한 시니어 여성을 대상으로 브라탑의 사이즈스펙을 개발하고 노년여성을 위한 사이즈 적합성이 높은 브라탑의 개발의 기초자료를 제공하고자 한다. 그 연구결과는 다음과 같다. 1. 시니어 집단의 체형차이를 분석한 결과 액티브시니어와 시니어는 20대보다 젖가슴과 배부위가 발달한 땅콩형 체형이며 젖가슴이 처지고 벌어져 있으며, 이는 연령이 높을수록 큰 차이를 보이고 있는 것으로 나타났다. 액티브시니어와 시니어는 20대보다 상반신의 자세가 뒤로 젖혀져 있는 체형이나, 시니어는 액티브시니어보다는 상반신이 숙인체형으로 나타나 가령의 영향으로 상반신이 숙여진 체형임을 알 수 있었다. 2. 액티브시니어 브라탑 사이즈는 5% 이상의 다빈도 구간을 기준으로 하였으며, 컵사이즈를 2.5cm로 할 경우 75A, 80A, 80B, 80C, 85A, 85B의 6개 사이즈로 커버율은 52.57%이며, 컵사이즈를 5cm로 할 경우 75A, 75C, 80A, 80C, 85A, 85C, 90A, 90C의 8개 사이즈로 커버율은 84.29%이다. 3.시니어 브라탑 사이즈는 5% 이상의 다빈도 구간을 기준으로 하였으며, 컵사이즈를 2.5cm로 할 경우 75A, 80AA, 80A, 80B, 85A, 85B, 85C, 90A, 90B 의 9개 사이즈로 커버율은 66.19%이며, 컵사이즈를 5cm로 할 경우 75A, 80A, 80C, 85A, 85C, 90A, 90C의 7개 사이즈로 커버율은 79.72%이다. 브라탑의 디자인과 브라탑 컵의 커버력에 따라 각 타깃의 두 종류의 사이즈스펙을 선택하여 적용한다면 생산업체는 보다 적은 종류의 사이즈를 생산하여 재고에 대한 부담을 줄일 수 있어 생산효율을 높일 수 있을 것이다. This study aims to present source data for the development of high appropriate-size bra tops for senior women in the manner of developing the size specifications of bra tops for active senior women in their fifties and for older senior women in their sixties in consideration for their different somatotype characteristics and lifestyles depending on age. The results of this study are summarized as follows: 1. An analysis of differences in their somatotype between the two senior groups shows that active seniors and older seniors have a peanut-shaped somatotype featuring the more developed breasts and abdomen than those of young women in their twenties and also sagging and wide breasts, which are more remarkable with older age. It was found that both active seniors and older seniors had a body shape characterized by the leaning-back bust compared to those in their twenties, however older seniors had the more leaning-forward bust than that of active seniors, which suggests that aging has an effect on such the change in body shape. 2. The sizing of bra tops for active seniors was based on at least 5% of high-frequency interval: if the bra cup size is set to 2.5cm, six sizes including 75A, 80A, 80B, 80C, 85A and 85B lead to 52.57% of coverage rate; and, if the cup size is set to 5cm, eight sizes including 75A, 75C, 80A, 80C, 85A, 85C, 90A and 90C have 84.29% of coverage rate. 3. The sizing of bra tops for older seniors was based on at least of high-frequency interval: if the bra cup size is set to 2.5cm, nine sizes including 75A, 80AA, 80A, 80B, 85A, 85B, 85C, 90A and 90B lead to 66.19% of coverage rate; and, if the cup size is set to 5cm, seven sizes including 75A, 80A, 80C, 85A, 85C, 90A and 90C have 79.72% of coverage rate. Based upon the results above, it is concluded that if the two types of size specifications are selectively applied to target users according to the designs and cup coverage of bra tops, the manufacturers will improve their production efficiency by producing less different sizes of bra tops and thus lowering inventory burdens.

To increase the productivity and product quality of customized baseball jerseys, this study developed a multivariable system for a production process that efficiently controls diverse production management factors. The working time was measured through the establishment of a standard process where skilled workers and Chinese factory workers manufactured 5 sets of the same basic design jerseys. Based on the measured working time (1,136 seconds/per unit), the multi-variable process control system was developed, where hourly production management is possible according to the involved workers and equipment types. Each process was assigned accoding to the production management factors for a total of 28 standard processes. The processes were developed based on consideration of work characteristics according to the order of needlework of open-type set baseball jerseys with sleeves(the basic design of baseball jerseys)to result in a customized production system structure that could be set up with multi-variables. As a result, a total 12 types of systems were developed in consideration of the personnel involved and the number of equipments. The optimal production management system (with the highest efficiency compared to the number of workers) was A-2, B-1, C-1, D-2, E-2, F-1, and G-1, This system had extremely high efficiency and showed 99% assignment efficiency for the 7-person team, Though not optimal, possible process assignment for each working personnel is proposed as a reserve process in case work modification is inevitable due to malfunctions and the absence of equipments.

연구배경 본 연구의 목적은 컴프레션웨어 착용이 런닝시 유산소수행능력에 미치는 영향을 밝혀 보다 우수한 런닝용 컴프레션웨어를 개발하기 위한 기초자료를 제공하는 것이다. 연구방법 시중에서 판매중인 남성용 런닝 컴프레션웨어 2종의 설계 특성을 분석한 후 운동부하검사를 통해 이들의 착용이 유산소수행능력에 미치는 영항을 검증하였다. 연구결과 컴프레션웨어 A는 하의쪽에서 수평방향의 압박이 강하고 상대적으로 컴프레션웨어 B는 이와는 반대로 상의쪽의 압박이 강한 특성을 보였다. 컴프레션웨어 B의 하의에는 수축력을 보완하기 위한 밴드가 부착되어 있어 Stretch Shortening Cycle 작용을 강화하도록 설계가 이루어졌다. 운동부하검사에서는 대부분의 항목이 처치 간 통계적 유의차를 보이지 않았으나 운동지속시간과 최대산소섭취량의 평균에서 컴프레션웨어를 착용하는 것이 그렇지 않은 경우보다 우수한 결과를 나타났다. 운동 시 최대심박수를 증가시키기 위해서는 상반신에 강한 압박이 가해지는 컴프레션웨어 B를 착용하는 것이 더 유리하였다. 결론 본 연구는 런닝 중 운동능력을 향상시킬 수 있는 컴프레션웨어를 개발하기 위한 기초연구로 컴프레션웨어 착용이 일부 운동기능에 긍정적인 영향이 미칠 수 있음을 밝혔다. Background The purpose of this study is to provide base data needed for the development of improved men`s running compression wear by verifying positive effects on the aero capacity of the wears. Methods Design features of two compression wears were analyzed and the influences to the aero capacity were verified using incremental treadmill exercise testing. Result The compression wear A had more compression on the pants than B in a horizontal direction and the compression wear B had more compression on the shirt than A. The compression bands were attached only on the pants of the compression wear B, which is effective to assist the contractile force of muscles by `Stretch Shortening Cycle` effect. In the incremental treadmill exercise testing, there were no significant differences by the clothing treatments. But concerning the increments of means in the `exercise duration` and the `maximal oxygen uptake`, wearing the compression wear may has the positive effects to enhance the aero capacities. The compression wear B which has stronger compression on the upper body showed an advantageous result to increase the maximal heart rate. Conclusion The positive effects of compression wear to enhance some of exercise abilities were verified by the result of incremental treadmill exercise testing. This study can be used to provide baseline data for the development of new running compression wears with improved performances.

This study is to understand the preferences of pilots, flight engineers and crew who work in the same aircraft but are exposed to different working environments and perform different mission operations in order to develop an ergonomic flight jacket. Based on a preliminary investigation, a survey of 107 pilots and 36 flight engineers and crew was conducted. The results are as follows; Pilots can control the temperature inside the cockpit, so they are less exposed to the cold when working, while flight engineers and crew are exposed to the cold more because they have many external tasks. The reason for the problem of the current flight jacket was a difference in ranking between two groups, but the highest ranking was poor dimensional suitability due to the habit of wearing layers of clothing. As a result of preferred design, there were significant differences between groups in the item of overall style. Pilots preferred a bomber jacket style(P:68.2%, E&C:44.4%), on the other hand, flight engineers and crew preferred a field jacket style(P:26.2%, E&C:55.6%)(p<.01). They preferred a stand collar(P:71.0%, E&C:86.1%), a fastener slider for a front fastening(P:62.6%, E&C:61.1%), fastener tape cuffs(P:54.2%, E&C:47.2%), a jacket with a softshell(P:86.9%, E&C:83.3%), fleece as softshell material(P:88.8%, E&C:69.4%), and fastener sliders as a attaching method(P:69.2%, E&C:61.1%). A hem fastening will be selected differently according to the overall style of outshell. Additionally, they preferred more than 5ea pockets(P:51.4%, E&C:44.4%), fastener sliders as pocket’s fastenings(P:48.6%, E&C:61.1%), armpit ventilations(P:62.9%, E&C:58.5%). The results of above will be considered to design an ergonomic flight jacket.

This study has been undertaken as a basic research for automatic pattern design for baseball uniforms manufactured under custom-MTM system, propose building up of a system whereby various partial patterns are combined under an automatic design system and develop a multi-combination type pattern searching algorithm which allows development of a various designs. As a result of this, type classification based on pattern design elements includes side, open, collar, facing and panel type. Design have been divided into coarse classification ranging from level 1 to 7 according to pattern design elements, based on a design distribution chart. Out of 7 such levels, 3 major types determining design which are, more specifically, level 1 sleeve type, level 2 open type and level 3 collar type, have been taken and combined to determine a total of 12 types to be used for design classification codes. Respective name of style and patterns have been coded using alphabet and numerals. Totally, pattern searching algorithm of multi-combination type has been developed whereby combination of patterns belonging to a specific style can be retrieved automatically once that style name is designated on the automatic patern design system.
