  • This study aimed to develop an Arduino-based garment pressure device (APD) on the basis of using Single-Tact sensor by suggesting the reliable clothing pressure range and coefficient of selected sensors through the APD calibration process. Once the APD was validated, the pressure of the experimental men's lower body compression wears was measured using the APD and was compared to the pressure measured using the existing air-pack type pressure meter. The subjects were one mannequin and eight men in their 20's, and the trial compression wears were calf sleeves and pants. Clothing pressures were measured in hip, mid-thigh, calf, and ankle. In terms of the 99% confidence level, the experimental clothing pressure measured at the designated measuring points using the APD was considered identical to the one measured using an existing clothing pressure meter. Therefore, on the basis of the experiment results, this study demonstrated that the APD is as reliable as the existing clothing pressure meter within the pressure ranges of 0.54-16.79 kPa and 0.18-25.47 kPa as provided by the SingleTact sensor supplier's data on the basis of using an external ADC (Analog to Digital Converter) module.

  • This study is to measure the thermal resistance of 7 types of Parka of different materials with thermal manikin and to compare their effects on physiological responses & subjective wear sensations. Following are the results obtained from the experiments 1) From the thermal manikin experiment, i) As an outer layer, although not significant, water proof fabric was warmer than water proof-vapor permeable fabric. ii) In case of insulating material, down was better for thermal resistance than polyester wadding of the same thickness. Moreover, as the down was thicker, it had more efficiency in thermal resistance. However, the marginal efficiency of thickness was found to be decreasing. 2) From the male-subject experiments, i) Chest temperature, mean skin temperature & microclimate temperature showed the same results on thermal resistance as those of the thermal manikin experiment. ii) Only during rest periods, there was a significant difference among 5 insulating materials in the sense of microclimate humidity. The almost same conclusion was obtained from the above experiments. Even the outer layer did not significantly affect thermal resistance & subjective wear sensation, insulating materials had a significant influence upon them. But in case of 3.5 cm down, it gave less comfortable than that of the thinner. Therefore the optional one for the best comfort & thermal resistance among 7 combinatins is the outer layer of water proff-vapor permeable & insulating material of 2.1 cm down.

  • The propose of the study was to evaluate impression effects and likeness of clothing styles and make-up types. The stimuli were composed of 4 clothing styles(base, natural, romantic, classic) and 4 make-up types(no make-up, natural, romantic, classic). The subjects were 512 male and female university students in Daejeon and Chungnam province. The study consisted of a survey and quasi- experiment. The experimental materials used for this study were 16 stimuli, 32 hi-polar adjectives, and likeness scale were composed of 7-point Likert type scales. As a result, the clothing styles and make-up types effected on the 4 impressional dimensions: grace, evaluation, salience, and dynamism. The clothing styles effected on grace, salience and dynamism dimension and the effect of dynamism dimension was the most powerful among the dimensions. The make-up types effected on all of the 4 impression dimensions and the effect of salience dimension was the most powerful among the dimensions. The interaction effects existed between the clothing styles and make-up types in salience dimension. The likeness showed significant difference only on the make-up types. The effect of grace dimension was the most powerful among the dimensions. The main reason that make-up effect appears greatly could be analyzed into that clothes color is controlled by white. The results suggest the necessity of succession study about the effect of clothes color.

  • This study suggests quantitative guidelines for inside clothing temperatures to improve the heat tolerance of 20's females in summer. First, the inside clothing temperatures ($T_{cl}$) of each subject was measured in daily use. The subjects were asked to record subjective thermal sensations, clothing items worn, clothing weight, and activities during an experiment designed to determine the comfort zone of $T_{cl}$. In a thermally neutral state, the comfort zone of $T_{cl}$ was decided on a mean value $T_{cl}{\pm}1{\sigma}$. Second, the subjects were asked to wear clothing that would enable them to feel 'slightly warm but still comfortable'. The rest of the processes were the same as previous steps that were designed to understand the way and degree of clothing control. The comfort zone of $T_{cl}$ was decided in the same manner as the previous step. The two comfort zones were combined and named the combined comfort zone of the definitive comfort zone. The results were as follows: 1. Thermally comfortable $T_{cl}$, Hcl were $34.0{\pm}1.1^{\circ}C$, $40{\pm}9%%RH$ and the thermally comfortable ambient climate was $25.0{\pm}1.6^{\circ}C$, $53{\pm}7%$RH. 2. When subjects were asked to wear 'slightly warm but still comfortable', there were difference in thermally comfortable $T_{cl}$, clothing weight and clothing layer by subject. 3. In this study, the optimal $T_{cl}$ was decided on the mid-point of the definitive comfort zone of $T_{cl}$.

  • This study tests the performance of the recommended winter dress OnMapsi for an office worker through the analysis of skin temperature changes according to the heating environment. We tested and compared the effects of with/without undergarments for 4 male subjects in an artificial-climate chamber with two air temperatures of $19^{\circ}C$ and $22^{\circ}C$, $50{\pm}10%$ R.H. During the 60 minute experiment that simulated office work, the subjective feelings (that included thermal, humidity and comfort sensation, and skin temperature) were measured at equal intervals. The results show that the forehead and chest skin temperatures were not affected by air temperature or clothing type, while the hand and foot skin temperatures were affected at $0.3-0.9^{\circ}C$ depending on clothing type and $1.9-2.2^{\circ}C$ depending on air temperature. The mean skin temperature was decreased by the experimental time pass more with regular formal wear than with OnMapsi. The second experiment located the ambient temperature in which subjects wearing OnMapsi show equal skin temperaturesto those without undergarments at $22^{\circ}C$. Therefore it is possible to decrease heating temperatures to $18-21^{\circ}C$ in the office for winter OnMapsi wear that produces a skin temperature and thermal sensation that is the same as those at $22^{\circ}C$.

  • The age after the French Revolution was the period of experiment and change in dress for both men and women. Directly after the close of the Reign of Terror, Directoire(1795-1799) became the extreme fashion known as incroyables and merveilleuses which mean 'impossible' or 'unimaginable'. This study aimed to investigate the sociocultural phenomena which affect to clothing change through the French Revolution period and clothing analysis of incroyables and merveillues. Furthermore, this study will contribute to establishing the theory of clothing culture and help predicting clothing change in accordance with social circumstances. Incroyables and merveilleuses represent extreme opposites in sleekness of attire and grooming. Incroyables required an unkempt, wrinkled appearance and a contrived carelessness. Merveilleuseses show the exaggerated transparency and simplicity in the fashions of female. Also, they devoted to the worship of the antique and the masculine fashions. This fashion madness appeared as the result of revolutionary social change. Their costume showed characteristics of the transition period between French Revolution and Classic period. However, they simply carried existing tendencies to the point of caricature by an enthusiastic overstatement.

  • Effects of insulation after exposure of the extremities on the temperature regulation in clothed men were studied. Experiment was carried out with six males in a climatic chamber fixed at $10^{\circ}C$, $55\%$ R.H. treated with Type A (face only was exposed) and Type B (face and half of the extremities were exposed). Mean skin temperature fell greater in Type B due to intense vasoconstriction than in Type A. Rectal temperature rose a little in Type B and resumed in Type A without any significant differences in metabolism between two types of clothing. These findings suggest that Type B is more effective in physiological defense to the cold stimuli than Type A at least at $10^{\circ}C$.

  • This study was conducted to investigate the thermoregulatory responses and wearing behavior of the cold-sensitive men when exposed to the mild cold of 14$^{\circ}C$. Two sessions of experiment were carried out and five healthy young men for the cold-sensitive group(CSG) and four healthy young for the cold-insensitive group(CIG) participated in the study as subjects CSG maintained rectal temperature lower than CIG due to their thicker clothing resulted in larger decrease of rectal temperature. CSG maintained skin temperatures higher than CIG. CSG felt cooler than CIG but wore thicker clothing for thermal comfort and this made keep their sensation warmer. These results were discussed in terms of autonomic and behavioral temperature regulation.
