Random and/or periodic defects occur in all spun yarns. These irregularities can often lead to defects in finished fabric. Yarn evenness tests are used to obtain statistical data about yarn properties, such as CV%, which is useful in comparing several sets of similar data that differ in mean value but may have some commonality in relative variation. Although this statistical data is helpful in determining relative yam quality, accurate predictions of how the yarn will appear in fabric form are still difficult to obtain. As an promising alterative, wavelet analysis has been employed to localize yarn defect so as to predict the visual qualities of the fabrics.

본 논문에서는 이성간의 대화에서 여성을 상대로 이성에 대하여 관심이 있을 경우와 관심이 없을 경에 따른 성문 특성변화를 비교 연구하였다. 대화내용을 녹음한 음성신호의 분석을 거쳐 얻어낸 결과로부터 보면 여성은 자신이 관심을 갖지 않는 상대에 대하여서는 17.2％ 미만의 응답을 보여주는 반면 관심이 있는 상대에 대하여서는 45.1％ 좌우 또는 그 이상의 응답을 보여주고 있다. 대화 내용의 음성신호를 스펙트로그램으로 표현 하였을 경우 성문 특성의 변화는 매우 뚜렷하다. 주파수 측면으로부터 보면 여성은 관심 있는 이성과 대화할 경우 200Hz에서 450Hz 좌우의 기본 주파수 폭을 이루게 되지만 관심이 없는 상대에 대해서는 200Hz에서 320Hz 정도의 기본 주파수 폭을 나타내게 된다. 따라서 이성간 대화에서 이러한 성문 특성의 변화를 이용하여 상대방 호감도를 측정할 수 있는 제품 개발에도 본 논문에서의 연구내용이 용이하게 쓰일 것으로 예상하고 있다.

Nowadays, many robots have evolved to imitate human social skills such that sociable interaction with humans is possible. Socially interactive robots require abilities different from that of conventional robots. For instance, human-robot interactions are accompanied by emotion similar to human-human interactions. Robot emotional expression is thus very important for humans. This is particularly true for facial expressions, which play an important role in communication amongst other non-verbal forms. In this paper, we introduce a method of creating lifelike facial expressions in robots using variation of affect values which consist of the robot's emotions based on emotional boundaries. The proposed method was examined by experiments of two facial robot simulators.

Voigt Model assumed for creep was used to obtain the viscoelastic properties of fabrics in thickness direction and the governing equation was derived. The weights were specially designed and calibrated for constant stress applied to fabrics and the 1 ${\mu}{\textrm}{m}$ resolution laser displacement sensor was attached in order to measure the variation of strain. Ten fabric samples were used. The few steps of strain showed according to the internal structure of fabrics. Also correlations the Hand Values from KESF with the spring and damping coefficients were considered.

There is substantial evidence that anatomical connections and functional interactions exist between vestibular and autonomic systems. Heart rate variability (HRV) including mean, standard deviation, coefficient of variation (CV), power spectrum was analyzed for evaluation of the physiological role of the vestibular system on control of heart rate in rabbits. In anesthetized rabbits, electrical stimulation of the vagus nerve decreased heart rate and decreased LF/HF by increasing HF. On the cervical sympathetic nerve increased heart rate and increased LF/HF by increasing LF. Atropine, cholinergic blocker, increased heart rate and increased LF/HF by reducing HF, and propranolol, ${\beta}$-adrenergic blocker, decreased heart rate and decreased LF/HF by reducing LF> In unanesthetized rabbits, stimulation of the vestibular system induced by rotation or caloric increased heart rate and increased LF/HF by increasing LF> Also electrical stimulation of the vestibular nerve produced the same of effects as rotation or caloric in anesthetized rabbits. These results suggest that Stimulation of the vestibular system increased heart rate not by inhibiting the parasympathetic nerve but by activating the sympathetic nerve.

The type of physiological stress involved in driving is probably complex, and a comprehensive study involving recording of physiological signals such as electrocardiogram(ECG), electromyogram(EMG). Changes in relevant Physiological parameters, such as ECG, EMG, reflected changes in driver status. In order to derive the mental and physical load of driving a motor vehicle from driving behaviour alone it is necessary to establish the relationship between changes in a driver's physiological parameters and behavioral parameters. In this study, we choose two different condition and investigated driver's status using HRV analysis method. Many previous studies have shown that increasing driving time causes a variation of HRV signal.

최근 고감성 PET 사를 이용하여 생산한 PET 직물은 고감성 의류용 직물로서 많이 사용되고 있다. 이러한 고감성 의류용 PET 직물은 다양한 공정을 거치면서 장력이나 열 등의 영향을 받으므로서 사의 물성의 변화를 초래하여 감성 의류용도의 PET 직물에 많은 결점을 유발 시키므로서 직물 생산 시 공정조건 설정 등의 어려움에 직면하고 있다. 이러한 고감성 의류에 치명적인 문제를 유발하는 문제점에 관한 감성사 제조 시의 공정조건 변화와 관련된 연구 논문은 많이 발표가 되지 못하고 있다. 따라서 본 연구에서는 국내 7개 원사 Maker의 Denier 별 PET 사의 물성을 균일한 길이의 Layer를 설정하여 분석, 조사하고 Layer 별 물성 차이와 습ㆍ건열 열처리 온도에 따른 사의 수축률 등을 비교하므로서 감성 의류용 직물 생산에 필요한 기초 물성 Data를 제공하고 PET 사의 품질향상을 도모하므로서 최종 감성 의류용 직물 소재 개발에 기여할 수 있는 기초자료를 제공하고자 한다.

This study deals with Rhythm which is one of aesthetic variables. Aesthetics among the factors of consumer preference has been importantly considered in competitive market environment. Therefore , consumers' purchasing standard has been also changed as their consciousness has been changed according to the variation of their lire style. Besides, the technique and method of design faces up to the change because of consumers' diverse wishes. Hence, to satisfy consumers' needs and the market front now on characterized as the short durability cycle of products, a distinctive design should be developed in the form of products that can be an important factor to attract consumers preference. So, in this study, 1 will try to understand typology based on a categorization theory and the conceptual structure of aesthetics, which are importantly considered at the same time. In addition, I will establish a new design process by extracting Rhythm affecting aesthetic. Ultimately, this study aims develop more consumer preferring design beyond the limit of a designer's idea and design generation by the result of this study.

In this study, we estimated the behavior of the diversity of physiological responses under varied physical environmental factors by measuring variations of heart rate variability (HRV), an index of activity of cardiac autonomic control. Seven healthy young male adults consented and participated in the study. The environmental conditions consisted of thermal, lighting, and acoustic conditions. Two components of HRV were measured. one was the low frequency (LF) component of HRV, which provided a quantitative index of the sympathetic and parasympathetic (vagal) activities controlling the heart rate (HR). The other component measured was the high frequency (HF) component, which provided an index of the vagal tone. The percent contribution of physical environmental factors to the variations in HRV indices were calculated by ANOVA. The contribution of physical environmental factors to the variations in HR was higher than the contribution of HF and LF. However, the contribution of these factors was lower than the contribution related with individual difference in all indices. This result showed that the individual diversity of physiological responses is not a negligible quantity.
