The purpose of this study was to analyze the reality of clothes-wearing among physically disabled women and propose trouser designs. As a research method, an in-depth interview method was adopted for 10 women in their 30s and 50s with lower limb disabilities who could wear trousers and use wheelchairs. The study results identified the following factors that should be considered in the design of trousers. First, a semi-casual design that could hide physical deficiencies, was not different from ready-made clothes and enabled various looks was desirable. Second, the proper material would have little transformation in the form, have remarkable durability and laundry fastness, two-directional stretch, and hide deficiencies with a sense of thickness and density. Third, an "L-frame" pattern in a sitting position, and a straight fit were desirable. Finally, pockets can impose pressure according to their form, size, position, and sewing method, highlighted the need for a sewing approach to minimize seams in the fabric. For adjustment, an elastic band would be a good choice in terms of type, length, position, and material as it could satisfy both the convenience of putting on and taking off and comfort in wearing at the same time. Decorative design details can also impose pressure according to a sense of thickness, which means that they should be avoided in parts that are close to the body or can impose pressure according to posture.

The purpose of this study is to provide basic information for the development of pants patterns with a high level of fit and comfort through calculating surface variations of lower body parts by movement, grouping them into factors, and analyzing how their surface variations link to one another. The achieved results will help determine essential elements for constructing pants patterns, such as key measurements of lower body parts, the amount of ease values and selection of fabrics, which should be taken into consideration for allowing better movement in clothing. The study required lower body 3D scanning of women for analysis, and 13 women between the ages of 20-24 participated in the scanning, which was done by using Artec Eva 3D scanner. Their scanned data were digitalized and converted to measure the values of their lower body surface length and girth in pre-determined positions such as walking, stair climbing and sitting on a chair. These measurements have been statistically analyzed through SPSS 21.0 to obtain the average amounts and rates of extension for each of the measurement item. Some of the highlighted study results are as follows: The surface length and girth measurements were grouped into 4 factors based on their average extension rates. The results from correlation analysis between measurement items within each factor demonstrated that common items linked to all the changes in the values of other items in the three movements. But in most cases, items were not always correlated with each other for different movements. The results also showed that there were correlations between girth measurements, length measurements, and girth and length measurements. Therefore, key measurements for daily pants should be determined within reasonable estimations between relevant measurement items, while the measurements for work pants, which often withstand certain postures or repetitive movements, may require measurement items that are appro priate for, and closely related to, certain movements or tasks.

This study developed a method of calculating dynamic wearing ease (DWE) to make patterns for coverall work clothing. The DWE was measured from 3D body scan data of women in their 20's (n = 10). The body postures adopted for measuring the DWE were sitting and deep bending postures. Three types of experimental patterns (A, B, C) were developed. The DWE was applied at the waist and hip lines of the pattern. The location and size of the DWE varied from one pattern to another. For pattern B, DWE of 8.8cm was applied at the back of the waistline. For pattern C, 5.3cm was applied at the waist for the center back line, and 3.5cm was applied at the under hip level. The comfort of the experimental clothing was evaluated in six body postures. The results showed that patterns B and C were comfortable at the crotch, shoulders, and arm pits. Pattern C was comfortable at the hip and crotch areas in the arms lifting-up posture and the stepping-up posture. The appearance and fit of the experimental clothing were evaluated by the panels. Patterns B and C fitted better than pattern A at the abdomen. The results suggest that DWE should be applied at the waist and hip levels for making coverall work clothing patterns.

In this study, we have developed the ergonomic pattern from the 3D human body reflecting cycling posture and extensibility of the stretch fabrics. Adjusting pressure level in the construction of athlete's tight-fitting stretch garments by reducing the original pattern is a challenging subject, which influence on the performance of the wearer directly. Therefore, in this study, relationships between the reduction rates of the 2D pattern obtained from the 3D human scan and resultant clothing pressure were explored to improve the fit and pressure exerted by reduced clothing pattern. Subjective wear sensations of the experimental garments were rated using a seven-point Likert scale on two consecutive days. While wearing the garments, subjects were asked to take five different postures including waist flexion, sitting and others. A Likert-type scale was used for the evaluation, with 7 points indicating the best fit in tight-fitting pants. Comparing 2/3T-pattern with T-pattern, the latter was superior to 2/3T-pattern in terms of adhere well to the waist and hip area in the 0.032 significance level. T-pattern was superior to 2/3T-pattern in terms of fitting and wear comfort. As results, the pattern obtained from the flexed body reflecting cycling posture already included the contraction and extension of the skin while cycling posture, so that the extra ease for movement and good fit was not need to be considered. The optimized reduction rates were determined with the proposed reduction rate, the resultant pressure range was within the range of $0.5{\sim}3.0gf/cm^2$ at eight locations on the body except front waist band and thigh band.

The construction of athlete's tight-fitting garments by reducing the elastic knit pattern is an interesting subject, which directly influences the performance of the wearer. Therefore, relationships between the reduction rates of the men's pants pattern obtained using measurements of Size Korea 2004 and clothing fitting were explored to improve clothing comfort. Two pattern making methods were developed and the reduction rates were applied to those pants depending on the parts of human body. The four male subjects were university students in the ages of 20 to 24. Subjective wear sensations of the experimental garments were rated using seven Likert scales during 4 consecutive days. While wearing the garments, subjects were kept four various postures including waist flexion and sitting etc by requests of the researchers. Likert type scale was used for the evaluation and 7 point indicates that it gave the best fit as tight-fitting pants. As results, differences in the length and girth between two piece pants pattern(style 1) and one piece pants pattern(style 2) were 0.0$\sim$0.3cm. Between two pattern making methods, one piece pants pattern(the style 2) was superior to two piece pants pattern in terms of subjective sensation and fit. Among eight tight-fitting pants, C, D, G, H pants were superior in terms of fitting and stability of waist and hip part to the others. ill case of tight-fitting pants, the reduction rate of the pattern in the course direction, the reduction rate of T2/3(66%) was better than that of T/2(50%), but the reduction rate of the pattern in the wale direction, that of the part of crotch, which was very sensitive part, should be kept the same as suggested earlier by Ziegert(1988).

본 연구는 등(Wisteria floribunda(Willd.) DC.)으로 피복된 그늘시렁($L\;7,200{\times}W\;4,200{\times}H\;2,700mn$)의 엽면적지수(LAI)의 변동에 따른 온열환경을 규명하고자 한 것이다. 이를 위해 진주시내 광장($N35^{\circ}10^{\prime}59.8^{{\prime}{\prime}}$, $E128^{\circ}05^{\prime}32.0^{{\prime}{\prime}}$, 표고: 38m)의 등으로 피복된 그늘시렁 하부와 햇빛에 노출된 포장지를 대상으로 맑은 날 미기상을 측정하였다. 범용온열기후지수(UTCI)를 산정하기 위해 봄철과 여름철의 미기상환경으로서 지상 60cm 높이에서 기온, 풍속, 상대습도 그리고 6방향의 장파 및 단파복사를 2017년 4월 9일부터 8월 27일까지 측정하였다. 또한, LAI는 LAI-2200C 수관분석기로 측정하였다. 18일간 오전 10시부터 오후 4시까지의 앉은 자세의 인체가 흡수한 매 1분 간격 인체-생기상학적 자료를 분석한 결과는 다음과 같다. 측정기간 동안 햇빛노출지에 비해 그늘시렁 하부의 일평균 기온은 $0.7{\sim}2.3^{\circ}C$ 낮았으며, 일평균 풍속과 일평균 상대습도는 각각 0.17~0.38m/s와 0.4~3.1% 높았다. LAI와 쥴리안 데이 사이의 회귀식은 $y=-0.0004x^2+0.1719x-11.765(R^2=0.9897)$였다. 그늘시렁 하부의 일평균 평균복사온도($T_{mrt}$) 값은 햇빛 노출지에 비해 각각 $11.9{\sim}25.5^{\circ}C$로 낮았으며, 최대 평균복사온도 감소(${\Delta}T_{mrt}$)는 $24.1{\sim}30.2^{\circ}C$였다. LAI의 변동에 따른 햇빛 노출지 대비 일평균 $T_{mrt}$ 감소율(%) 사이의 회귀식은 $y=0.0678{\ln}(x)+0.3036(R^2=0.9454)$였다. 그늘시렁 하부의 일평균 UTCI 값은 햇빛 노출지에 비해 각각 $4.1{\sim}8.3^{\circ}C$로 낮았으며, 최대 범용온열기후지수 감소 값(${\Delta}UTCI$)는 $7.8{\sim}10.2^{\circ}C$였다. LAI의 변동에 따른 햇빛 노출지 대비 일평균 UTCI 감소율(%) 사이의 회귀식은 $y=0.0322{\ln}(x)+0.1538(R^2=0.8946)$였다. 종합적으로 보면 여름철에 덩굴식물로 피복된 그늘시렁에 의한 녹음은 차양에 의한 $T_{mrt}$의 감소를 통해 낮 동안 UTCI를 감소시킴으로써 열스트레스를 매우 강한(UTCI>$38^{\circ}C$) 또는 강한(UTCI >$32^{\circ}C$) 단계에서 강한(UTCI >$32^{\circ}C$) 또는 보통(UTCI >$26^{\circ}C$) 단계로 낮추어 준다. 따라서 여름철 열스트레스를 완화하고 쾌적한 인체 온열쾌적성을 제공하기 위해서는 덩굴식물로 피복된 그늘시렁의 도입은 필수적이다. 하지만 폭염 시에는 덩굴식물로 피복된 그늘시렁 하부의 온열환경도 이용자들에게 매우 강한 열 스트레스(UTCI >$38^{\circ}C$)를 주므로 노약자의 옥외활동은 자제시킬 필요가 있다고 판단된다.

Objective: This study aims to develop and scientifically investigate the efficacy of the Spine S-curve Reactive Backrest that responds to the spine curvature of the user when seated, and maintains and enhances the natural S-curve of the lower back, thereby helping to relieve fatigue, correct posture and prevent spine deformities. Background: The focus of current development, design guidelines and/or standards for office chairs is mainly placed on the chair's dimensions, incline angle, adjusting features and lumbar support. Research and development was called for developing a chair backrest that maintains and improves the S-curve of the full spine. Method: The Spine S-curve Reactive Backrest was ergonomically designed to maintain correct posture and enhance user comfort. When leaned on, the backrest responds to the user's spine line and the whole lower back sits closely against the backrest, thereby aligning the user's lower back and backrest as one to maintain and improve the natural S-curve formation of the spine. In order to evaluate the efficacy of the newly designed chair (new design) and the comparison target (chair), five male college students of standard body type with normal spine curvature were selected as test subjects, and a motion analyzer and electromyography were utilized to measure S-curve and erector spinae muscle activity when seated. Results: The spine S-curve was better maintained and improved when sitting in the new design than in the comparison chair. Particularly notable was the greater displacement gap of the thoracic spine than the cervical spine, and also that of the lumbar more than the thoracic spine, with the increase of the backrest tilting angle. Furthermore, the electromyogram results showed the new design caused a lower fatigue level of the erector spinae muscles compared to the comparison chair, and also earned a higher preference in the subjective opinion results. Conclusion: The newly designed chair in this study responds to the user's spine curvature and maintains and enhances the lower back's natural S-curve, and thereby relieves fatigue, promotes better posture, and helps to prevent spine deformities better than existing office chairs. There is a need to widely introduce and supply this new design. Application: The new design is applicable to office and student chairs, and is expected to improve concentration and work efficiency.
