This study investigated the effects of persimmon-dyed clothing materials upon thermophysiological responses and subjective comfort sensations during exercise and rest in a warm environment. Six healthy, untrained women participated in two separate testing sessions, with cotton materials dyed with astringent persimmon extract (DC) and undyed cotton materials (UDC). The physical characteristics associated with heat and moisture transfer were improved in DC; also, stiffness, anti-drapery stiffness and crispness in the primary hand values were higher in DC. The experimental protocol consisted of a 10-min rest, 15-min exercise on a treadmill (at ${7km{\cdot}h^{-1}}$) and 25-min recovery at $28{\pm}0.2^{\circ}C$ and $50{\pm}3%\;RH$. The results were as follows: When wearing DC rather than UDC, mean body temperature, heart rate, heat storage and body mass loss were significantly lower during the whole experimental period. Clothing microclimate temperature showed different profiles between the two clothing materials, being lower with DC than UDC during the first half of exercise and the second half of recovery. Clothing microclimate humidity was significantly lower with DC than UDC during the whole experimental period. When wearing UDC, subjects felt significantly warmer and less comfortable during exercise, and sensed greater humidity during exercise and recovery. These results suggest that eco-friendly clothing materials dyed with astringent persimmon extract can reduce exercise-induced heat load and improve subjective sensations when exercising and resting in a warm environment, due to greater heat dissipation from the body to the outside environment compared with undyed clothing materials.

The objective of this study is to investigate the relationship between clothing microclimate and physiological responses, including subjective sensations, when, in a $15^{\circ}C$ environment, a range of temperatures inside clothing is broadly produced from using various combinations of upper and lower garments. Six male subjects participated in the investigation and the results were as follows. For all types of inside garments, the temperature of the clothing was lower than the skin temperature for the whole body in each case. The mean temperature for inside clothing ($\bar{T}_{cl}$) significantly showed the highest correlation with mean weighted skin temperature (r = 0.816) and was less positively correlated with the temperature of the inside clothing at the chest (r = 0.326) (p < .01). Values for both the energy expenditure and the heart rate were less positively correlated with the clothing microclimate (p < .01). The change of body heat content showed a negative correlation with the surface temperature of the innermost clothing (r = -0.519) and there was a difference between the innermost surface temperature and the outermost surface temperature of the clothing at the chest (r = -0.577). As td increased, the increase of body heat content declined (p < .01). There was a negative correlation between body fat and some of the temperatures inside the clothing (p < .01) and body fat had no significant correlation with the humidity inside the clothing. Subjective sensations were more highly correlated with $\bar{T}_{cl}$ than with the temperature of the inside clothing at the chest and had not significantly correlation with the humidity of the inside clothing. In conclusion, through these results, it can be seen that the temperature inside the clothing was related to various physiological responses and subjective sensations, and that the mean temperature of the inside clothing ($\bar{T}_{cl}$) showed a higher relationship with the temperature of the inside clothing at the abdomen than that at the chest.

This study examines the wearing conditions of working clothes according to the working environment and working processes at machinery, automobile, shipbuilding industry sites. It also investigates the relationship between the wearing sense of working clothes and the overall comfort according to work processes. The hazardous working environment was high in the order of the shipbuilding industry, machinery, and automobiles. The findings on the harmful overall work environmental factors were the noise, heavy dust, and noxious fumes, respectively. In general, the satisfaction with the wearing performance of working clothes was low especially with regard to sweat absorbency, sweat permeability, body protection and covering, and the work motion suitability. In respect of the correlation between the overall comfort and the wearing sense of working clothes, the satisfaction was decreased in the order of movement comfort, sensual comfort, and physiological comfort.

In the current fashion design, the 'environmental friendliness' affects the practically and conceptuality in all industry and culture sectors. This study seeks to examine specific design elements as the content of design factors in environment oriented fashion. The subjects of this paper are studied through scholarly journals that are confined to those from 1990 (when naturalism and ecology trends started to be in fashion) to February 2009. This study used 'Naturalism', 'Green', 'Environment-friendly', 'Eco', 'Sustainable', 'Well-being' and 'Lohas' as key words for the literature search. The analysis is performed through a content analysis and the unit of analysis is based upon the adjectives, nouns, and phrases related to the content of the design elements such as line, color, and textiles. In the results, more expression is natural, minimal, transformable, and sportive style in line, YR, white, soft, pale, and dull tone in color. The prominent textiles and texture were natural fabrics, environment-friendly fabrics, recycled fabrics, natural dyeing, functional finishes, rustic surfaces, flexibility, and extensibility. The results of this paper will help in future fashion design product development for environment-friendly fashion brands.

To prevent increasing instances of heat-related illnesses due to heat waves generated by climate change, a customized thermal environment index should be developed for outdoor workers. In this study, we conducted sensitivity analysis of the Masan harbor during a heat wave period (August 9th to 15th, 2013) using the MENEX model with metabolic rate and clothing-insulation data, in order to obtain realistic information about the thermal environment. This study shows that accurate input data are essential to gather information for thermophysiological indices (PST, DhR, and OhR). PST is sensitive to clothing insulation as a function of clothing. OhR is more sensitive to clothing insulation during the day and to the metabolic rate at night. From these results, it appears that when exposed to high-temperature thermal environments in summer, wearing highly insulated clothing and getting enough rest (to lower the metabolic rate) can aid in preventing heat-related illnesses. Moreover, in the case of high-intensity harbor work, quantification of allowed working time (OhR) during heat waves is significant for human health sciences.

This study explores the determinants of clothing disposition and examines their effect on the dimensions of clothing disposition behavior. The data of 316 women were collected nationwide using an online self-administered questionnaire. This study initially identified five types of disposition behavior as revising, permanent separation, giving away, selling, and donating to charity. Exploratory and confirmative factor analysis identified the underlying determinants of clothing disposition as self-concept, reusability, economic factor, social environment, affective association, storage, fashionableness, and a sense of belongingness. Structural equation modeling was conducted to examine the relationships between variables. The results demonstrated that six out of eight determinants significantly affected clothing disposition behavior. The effects of social environment and a sense of belongingness were relatively strong determinants that influenced the four types of disposition behaviors. However, self-concept and affective association did not influence the disposition behaviors. A series of one-way MANOVA was conducted to determine the effect of the eight demographic variables on the four modes of clothing disposition. Giving away, permanent separation, and donating to charity differed significantly in the groups of three demographic variables such as age, monthly income, and marital status. This study empirically elucidates what criteria consumers use when confronted with unused clothing and how the determinants of clothing disposition influence the modes of clothing disposition behavior. This study provides a framework for clothing disposition behavior and its determinants as well as suggests a new approach to clothing disposition behavior and improvements in marketing decisions.

The study aimed to analyze the status quo of manufacturing work environment and the work clothes' clothing comfort and wearer mobility of welding and grinding work processes in the machine and shipbuilding industries in South Korea. A questionnaire survey was conducted for the study, which consisted of questions about work clothes' clothing comfort and wearer mobility according to body parts. The findings derived from the research were: the high impact levels of work environment factors on welding and grinding work processes were noise, metal fragment, superheat, toxic gas, UV ray factors. Subject workers' assessment of work clothes' clothing pressures were in the levels between 3 (i.e. moderate) and 4 (i.e. comfortable) in a range of 5-point scale. The impact levels of wearer mobility factor were high on the work processes of welding and grinding in machine and grinding in shipbuilding. While welding process in shipbuilding showed a 'moderate' wearer mobility level and this was because its work postures were uncomfortable yet the rate of the motion change was low. The consideration to develop the work clothes specialized for certain work processes should include the materials' protecting performance from the hazardous work environment factors; and work clothes' designs that provides workers with maximized clothing comfort and wearer mobility for bending or tilting postures of upper, lower and lateral body parts defined in the study.
