With a view of to providing basic data for designing male's and female's clothes, heslthy males and females(five each) were exposed to three different environmental temperature( $20{\pm}1.0^{\circ}C$ $28{\pm}1.0^{\circ}C$,$32{\pm}1.0^{\circ}C$ in the nude. Their adaptation of skin temperature, physilogical responses, oral temperature, blood pressure, pulse rates) and psychological reactions (thermal, comfort and perceptive sweat sensations) were analyzed to be as follows; The subjects's skin temperature had a similar look of adaptation, but the stability of skin temperature differed at the $20{\pm}1.0^{\circ}C$and at the $28{\pm}1.0^{\circ}C$ Males had higher skin temperatures at three environmental temperatures, but females showed a higher temperature change at the $20{\pm}1.0^{\circ}C$ and$28{\pm}1.0^{\circ}C$ and males at the $32{\pm}1.0^{\circ}C$ Thus females were more resistant to the cold, while male were more resistant to the heat. As environmental temperature increased, oral temperature and pulse rates also grew up. Females turned higher in oral temperature and lower in blood pressure, but both sexes had a normal range of physiological reactions. Even though three environmental temperature were same changes in thermal sensation at and in perceptive sweat sensation at $28{\pm}1.0^{\circ}C$and in perceptive sweat sensation at$32{\pm}1.0^{\circ}C$ the two sexes had the same response in comfort sensation at the three environmental temperature.

The purpose of this study was to design men's jacket pattern for variable body types by employing the data of wearing evaluation from experimental basic bodices selected by male subjects in the 30's. As a result of sensory evaluation, functional test and clothing pressure test by each type of experimental basic bodices, the 3rd experimental basic bodice was chosen to be a basic bodice type in this research since it showed a high degree in fitness and function, but a low in the clothing pressure test. As a comparison of one item from conventional jacket and sleeve pattern with each somatotype, the type 2(the standard somatotype) indicated a great fitness in both basic bodice type and conventional jacket pattern, whereas the type 1 and the type 3 showed higher fitness and moving function in the basic bodice type. In the making of men's jacket, many corrections were made in the front interscye breadth, back interscye breadth, front and back length, and shoulder line as adapting each body type. Thus, the ease-amount of chest circumference at scye for clothes should be established differently according to the size of chest circumference at scye.

This study was performed to investigate that wear training using thermal insulation with clothes has the effect on the human thermoregulatory response, especially on the heat tolerance. Twelve men and women in twenties wert divided into the control group, the training groups and each group except the control group had participated in wear training. The heat tolerance was assessed in all subjects who had participated in the experiment carried out in hot environment(40$\pm$1$^{\circ}C$, 50$\pm$5%RH) by such parameters as rectal temperature, skin temperature, systolic blood pressure, diastolic blond pressure, plume rate, total sweat volume, local sweat volume, subjective sensation, and the differences of heat tolerance in each group were compared. The results were as follows: In hot environment(4$0^{\circ}C$) the changing width of rectal temperature was decreased in the control and the heavy clothing group. Forehead and abdomen temperature in hot environment were significantly decreased after the training. Sweat rate was higher after the training than before. In all experimental groups, systolic and diastolic blood pries.;uses in hot environment(4$0^{\circ}C$) were significantly decreased after the training.

The From COVID-19 until recently, the demand for hiking has been rapidly increasing due to the popularization of mountain seekers.,On weekends and holidays, people who do not hike frequently while hiking in large and small mountains to see wildflowers and foliage in the mountains are more likely to be exposed to safety accidents due to an increase in sudden muscle use.,If you fall or get muscle damage during a hike, you can prevent a major accident with a simple treatment. In some cases, the error of first aid may permanently damage the important function of the body.,In particular, during a safety accident on a mountain, while climbing in light clothes, the body temperature rises due to the sweat that was shed at the beginning, and the blood pressure rises due to the contraction of the blood vessels due to the drop in body temperature from the top, resulting in an emergency such as cardiac arrest.,According to statistics from the National Park Service, nearly half (48%) of deaths in national parks are known to be sudden cardiac deaths.,There are many safety accidents that occur frequently in the mountains, but among them, we will study how to cope with acute diseases such as cardiac arrest due to increased blood pressure due to insufficient body temperature control, chest pain or dyspnea, and heart burden due to excessive hiking.

This study selected three model designs used for air injection type welding clothes designed for insulation purposes and analyzed the performance of each design. The bending characteristics were analyzed in order to identify the flexibility of the welded areas; subsequently, the seam breaking strength and water pressure resistance were analyzed to identify the bonding strength. In addition, two types of waterproof fabric, polyurethane (PU) coated 2 layer and PU laminated 2 layer fabrics, were used for a performance analysis, according to fabric processing specifications. The circle type showed the highest flexibility in the terms of bending characteristics that influence wearability and were followed by the wave and the straight type. In terms of breaking strength, the straight type showed the highest breaking strength, followed by the wave and the circle type. The water pressure resistance analysis found that the wave type was superior to the straight type in terms of water pressure resistance. The wave type is deemed to be a design type suitable for maximizing performance, provided that the issue of stabilization in the welding production process is addressed. Looking at the bending characteristics of waterproof fabric for each specification, the laminating waterproof cloth outperformed the coated waterproof cloth in terms of flexibility. However, in terms of seam breaking strength, the coated waterproof cloth outperformed the laminated cloth. In contrast, the water pressure resistance of the laminated waterproof fabric was found to be higher than the coated waterproof fabric, leading to the conclusion that the bonding strength of the laminated waterproof fabric is higher than that of the coated waterproof fabric based on the assumption of injecting air.

Muscle reduction owing to aging causes changes in physical function among the elderly. Fitness compression wear reduces fatigue by compressing the main muscles, expanding blood vessels, and rapidly discharging lactic acid. The effect of clothing pressure when wearing fitness compression wear for the elderly was objectively and subjectively evaluated for six women aged 55-64 years. The evaluation clothes were three types of tops and bottoms, one type of design (A) preferred among the existing compression wear, and two types of design (B and C). The objective evaluation items included clothing pressure, blood flow, surface temperature, and subjective satisfaction. It was found that clothing A had the highest clothing pressure in the straight posture and five fitness movements. Blood flow increased the most when wearing the evaluation clothing. The surface temperature was found to be the highest for clothing C, and subjective satisfaction was found to be the best when wearing evaluation clothing B. If the tensile strength was low and the tensile elongation was high, as in evaluation clothing B, it was recognized as appropriate clothing pressure, and the subject was subjectively satisfied. When manufacturing fitness compression wear in the future, it will be possible to increase users' objective and subjective satisfaction with wearing it, if the incision of the garment were placed at the location of the line of non-extension (LoNE), and appropriate material characteristics are applied.

This study shows the result of the survey conducted for male adults who had to use wheelchairs. The objectives of this study are to develop and improve the clothes for the disabled people and to make those garments put into practice. For this purpose, the survey was conducted at first so as to understand the situation of the disabled peoples wearing clothes and the garment demands. This survey is to suggest the suited form of the pants they want. The result of the study is as follows. 1) The average age of the subjects was 38.4 years old. They have used wheelchairs for 12 years on the average. Most subjects two limbs were paralyzed because of the acquired spinal paralysis. 60 percent of them were wearing the urine bags all the time. The average size of the pants they purchased was 39 inches, which means that their waist and abdominal circumstance were very big. 2) Regarding the situation of wearing habits, although the subjects usually purchased ready-to-wear, most of them are very dissatisfied with them. Especially, they considered the size as their main dissatisfaction. The main concern for buying garments was how comfortable and mobile they are while wearing them. They also needed outdoor garments. Lastly, they looked forward to the shop specialized in the garments for disabled people. 3) The functional pants for adult men using wheelchairs had the same zipper as that of general pants. The waist belt was made of rubber to reduce the pressure on waist and to cover 2 inches (5 cm) of waist circumference. Also it should be made to secure each button within the belt in accordance with size. Finally, it was designed as formal wrinkled pants that had pockets within the reach of hands when the disabled used wheelchairs.

The footwear such as socks and shoes is the clothing which are necessary to our life. In this study, clothing comfort of the footwear was carried out by physiological responses and subjective evaluation. As a result, the effect to walking comfort by the height of a heel in female shoes became clear. Then suitability evaluation system of shoes was proposed from the measuring results. On the other hands, the clothing comfort of the hosiery was evaluated from ECG analysis. By this analysis, it became clear that the factor which influences the clothing comfort of the hosiery was the clothes pressure in the hosiery. In the future, plane shape of the foot and solid shape must be considered in order to design the hosiery.
