  • 본 연구의 목적은 적합성과 기능성이 고려된 체형별 남성 상의 원형 패턴을 개발하는데 있다. 피험자는 인체계측자료와 측면체형 사진에 의해 선정하고, 체형은 굴신체형, 표준체형, 반신체형으로 분류하였다. 체형별 실험 원형 패턴의 평가를 위하여 기존원형을 선정하였으며, 연구 결과는 다음과 같다; 1. 착의평가 결과 표준체형은 대부분의 항목에서 적합하였으나, 굴신체형과 반신체형에서는 많은 차이가 있었다. 이러한 차이는 앞길이와 등길이 뿐만 아니라 여유량과 윗 가슴둘레에 서 나타난다. 앞품과 뒤품은 외관에 의해 많은 영향을 받으며, 증가된 옆품은 앞품과 뒤품의 부족분을 보충하는 역할을 하였다. 따라서 실험패턴은 기존패턴보다 각 체형에 더욱 적합하며, 체형 적합성과 동작기능성이 고려된 의복 제작을 위한 패턴설계는 인체의 구조와 동작연구에 의해 가능하였다. 2. 기본원형 패턴 설계를 위한 필요치수는 목뒤높이, 등길이, 앞길이, 윗 가슴둘레, 앞품과 뒤품이며, 체형분류의 기준은 윗 가슴둘레, 앞품, 뒤품, 앞길이, 등길이이다. 이와 같은 결과를 근거로 가슴둘레 선은 [(B/2+B/10), 뒤진동깊이는 [(B/10+목뒤높이/10)]로 설정하고, 앞내림은 1.5cm로 하였다.

  • The purpose of this study was to analyze the effect of the shape and attached position of E-textile-based stretchable sensors on motion-sensing performance and to investigate the requirements for the optimal structure of clothes for sensing limb motions. An experimental garment was prepared with different sensor shapes, and attachment positions. A child subject, wearing the experimental garment, performed arm and leg bending and extension motions at $60^{\circ}$, $90^{\circ}$ and $120^{\circ}$ motion angles, at a rate of 60 deg/sec. The changes in voltage triggered by the stretching and contracting of the fabric-sensor were measured, and an acceleration sensor was utilized to verify that the experimental motions were correctly performed. Dummy arms and legs of a child were manufactured to perform an identical test, in order to compare the dummy results with the actual human body experiment results. The analysis showed that the reproducibility and reliability of the rectangular sensor, showing uniform and stable were higher than those of the boat-shaped sensor, in both the dummy and the human body experiments. The attachment position of the sensor was more reproducible and reliable when placed on 4 cm below the elbow and knee joints in the dummy test, when placed in the joints of the elbow and knee, in children experiment. The appropriate shapes and attached positions of the sensor for sensing the motions were analyzed, and the results proved that motion-sensing of the human body is possible by utilizing flexible fabric-sensors integrated into clothes.

  • This study was performed for purpose of getting fundamental information requisite to wear velvet clothes that is more comfortable for the human body and also the environment. It was carried out in a human wearing test and thermal manikin test at the same time in a controlled-condition chamber. The experimental environment had a ambient temperature of 15$\pm$0.5$^{\circ}C$ with the relative humidity at 5$^{\circ}C$$\pm$5% and with air velocity at less that than 0.2m/sec. Velvet differ from common plain weaves in thermal properties because it's constructed in two parts one is ground part and the other part is pile part. In order to investigate the thermal resistance of velvet eight different combination of 4 velvet kinds and 2 lings kinds as experimental clothes. [(4 velvet kinds : Acetate cuprammoium Rayon Cotton Wool) (2 lining kinds : acetate viscose rayon)longrightarrow8 combination: Aa, Av, Ra, Rv, Ca, Cv, Wa, Wv: the simplified character] The results of this study can be summarized as follows : 1. For the regional thermal resistance the differences in eight clothes as well as differences in each part were significant. As a whole the breast part showed the highest thermal resistance and the leg part was higher than the shank part. The rank of the total thermal resistance was put at Wa>Wv>Ca>Cv>Aa>Av>Ra>Rv in this order. 2. Considered clothing microclimate microclimate temperature has a similar tendency to the total thermal resistance. It showed a significance in the differences of eight clothes and each parts. the belly part was highest in every combination. On the other hand for clothing humidity there was a significance between back and breast part only in the human wearing test. 3. It was indicated that CLO value was highly positively correlated with the clothings' weight and showed a high negative correlation with the air permeability.

  • The purpose of this study is to examine and to evaluate the wearing performance of pile materials to produce velvet fabrics which have excellent wearing comfort. Acetate velvet, Cuprammonium rayon velvet were combined as textiles for clothing and acetate and viscose rayon were as textiles for lining at the environmental condition of temperature $15^{\circ}C,\;18^{\circ}C,\;21^{\circ}C,\;24^{\circ}C$, relative humidity $50{\pm}5%$ and air velocity 0.25 m/sec. Wearing comfort among 4 materials combinations(Aa, Av, Ra, Rv) was examined and compared. The results are as follows. The investigation of mean skin temperature for environmental temperature and material combinations showed that the mean temperature had a significant difference at the p<0.01 level in accordance with environmental temperature and material combinations.(Aa>Av>Ra>Rv) Moreover, in clothing climate only clothing temperature tended to increase almost linearly but at $24^{\circ}C$ there was no significant difference among textiles for lining compared with the other environmental temperatures. In subjective sensations thermal sensation and comfort sensation showed a significant difference in environmental temperatures and materials.(Aa>Av>Ra>Rv) Though a subject felt warmer, more humid, and more uncomfortable at $24^{\circ}C$ for all of the material combinations comparing with the other temperatures, there was no significant difference in materials.

  • This study aimed to determine the effects of the shape and attachment position of stretchable textile sensors coated with carbon nanotube on their performance when used to measure children's joint movements. Moreover, the child-safe requirements for fabric motion sensors are established. The child participants were advised to wear integrated clothing equipped with the sensors of various shapes (rectangular and boat-shaped) and attachment positions (at the knee and elbow joints or 4 cm below the joints). The voltage change induced by the elongation and contraction of the fabric sensors was determined for arm and leg flexion-extension motions at 60 deg/s (three measurements of 10 repeats each for 60°and 90°angles, for a total of 60 repetitions). Their dependability was determined by comparing the fabric motion sensors to the associated acceleration sensors. The experimental results indicate that the rectangular-shaped sensor affixed 4 cm below the joint is the most effective fabric motion sensor for measuring children's arm and leg motions. In this study, we designed a textile sensor capable of tracking children's joint motion and analyzed the sensor shape and attachment position on motion sensing clothing. We demonstrated that flexible fabric sensors integrated into garments may be used to detect the joint motions of the human body.

  • This study examined energy saving and elevating the worker's neuro energy (comfort, concentration, physical, and psychological stability) by compensating for the unpleasant tactile sensation to stimulate auditory and olfactory senses and reduce energy consumption. The experiment was conducted in an environment test room under the test conditions of temperature $25[^{\circ}C]$, relative humidity 50[RH%], illumination 1,000[lux] and air current speed 0.02[m/sec] by stimulating the auditory senses with a 1/f change in rhythm and the olfactory senses with an aroma scent. The experiment utilized the method of EEG, which evaluates human body's psychological status via tactile means, and the method of the vibra image, which evaluates the learning abilities, HRV and human body's psychological status via non-tactile means. The subjects were selected as eight university students (four males and four females) in their 20s, the type that have high relative ${\alpha}$(8~13[Hz]) activation in occipital lobe, which brings the highest level of mind stability and concentration, who had no difficulty in physical activities. The subjects' posture and physical activity was fixed to 1met - when the subjects are seated and relaxing in a comfortable environment - and their clothes condition was standardized as 0.7clo. As a result, the sentimental and psychological stability and concentration were the highest in the multisensory stimulation of jasmine scent and change rhythm of an a=1.106 sound source. In addition, under this condition, the relative $M{\alpha}$ and relative $M{\beta}$ increased by 70.49[%] and 89.72[%], respectively; the HRT decreased by 39.09[%]; and the fatigue and tension/anxiety decreased by 36.85[%] and 15.54[%], respectively.
