This study identifies Japanese study content on heat stroke prevention measures using clothes, provides basic data for quantitative wearing assessment studies, presents a developmental direction for those, and helps invigorate further research. Studies were collected concerning clothing-based heat stroke measures in order to analyze the following factors: current status of heat stroke by industry and working environment, heat stroke and body cooling method, clothing microclimate and air circulation in a hot environment, hot environments and wearable sensors, and heat stress reduction and skin exposure. The current WBGT standard does not consider the diversity of wearing clothes according to the working environment. Therefore, it is preferable to add a correction value in consideration of design, materials, and ventilation to prevent heat strokes. For the heat stroke and body cooling method, wearing water-perfused clothing is effective to reduce heat stress and maintain exercise ability. Changing the material and design of clothing or wearing air-conditioned clothing can improve ventilation and the clothing microclimate. However, further evaluation is needed on the effectiveness of air-conditioned clothing as a heat stroke prevention product. The measurement method using a wearable sensor can provide real-time data on the body response due to working in a hot environment. Therefore, it is an effective alarm for heat stroke. Skin exposure area and heat dissipation efficiency should be considered to prevent heat stroke. Reducing the covering area by exposing the head, neck, and limbs, and wearing breathable material can prevent heat stroke from increased body temperature.

This study was conducted to suggest an appropriate jacket bodice pattern for elderly women by comparing the developed pattern with existing ready-made jacket pattern. The developed jacket bodice pattern was produced from the basic sloper in which elderly women's somatotype was fully reflected, by using the newly developed 3D pattern design system. Subjects were 6 elderly women aged from 60 to 69 who have average somatotype in their age group. This study carried out pattern analysis and self-sensory test with three ready-made jackets(national brands) and suggested a developed jacket pattern based on the results. According to the self sensory test results of ready-made jacket, wearing fitness among brands was significantly different even though those brands were same B91 size. The results of ready-made jackets' pattern analysis, size differences among patterns have influenced wearing fitness. The basic numerical formula for the jacket pattern considered elderly women's somatotype were as follows; $B/4+2{\pm}0.2{\sim}0.5$(difference of front and back), $W/4+2{\pm}0.2{\sim}0.5$(difference of front and back), H/4+2~7(ease amount), armhole depth B/4, chest width B/6+1, back width B/6+3 and back neck width B/12+0.5. According to the results of the developed jacket's appearance evaluation, it earned higher scores in silhouette and ease amount, confirming that the developed jacket is appropriate for the elderly women. Also, in the evaluation on space length, the developed jacket pattern was evaluated to allow proper space length in all around of measurement parts.

This study was aimed to find out the problems of wearing flame-proof clothing and to analytically assess functional working-clothes, thus to propose a new design. We carried out a questionnaire with workers in the field and evaluated the facility for wearing, the sensation of wearing and clothing microclimate in the environmental chamber. We found out the problems were in the parts of neck, armpits, armhole, sleeve, crotch and suspenders. Thermal sensation, wet sensation and comfort sensations were evaluated to be 'hot', 'wet' and near to discomfort', respectively. Therefore, improvement of movement and air permeability is needed. If we can add gusset on armpit for air permeability, this gusset will enable to enlarge the surface in armpit area and finally give a movement efficiency. We suggested several new partly modified design for flame-proof clothing which can be applied to other protective clothing for improvement. This must be further considered in the ergonomic evaluation of new proposed functional working-clothes as well as in the suggestion of design.

A diverse range of products are currently being sold; however, it is very difficult to purchase All-in-One patterns that reflect the body types of the elderly stage in the open market. This study is to develop specialized All-in-One patterns by assessing obese body types characteristics of the elderly social class. Five healthy women with typical obese body types in the elderly stage with busts, waists, and hips surpassing 100 cm were chose as test subjects. The three subjects for the wearing experiment are those with more than one year of experience wearing a bodysuit. A self-evaluation was made three times by looking in the mirror. The data from this study was processed to find averages and deviations; in addition, and a t-test was performed using the SPSS 24 statistical software. A total of 13 body parts were measured prior to and while wearing the specialized All-in-One patterns. Significant results were obtained from all 12 items. All-in-One for research appears to have produced a high level of satisfaction for subjects. This study can provide basic data on elevating the levels of satisfaction of the consumers in their elderly stages with special body types that deviate from standard body types at the time of wearing garments as well as for inner-wear companies to graft this market as a high-value-added niche market.

A tool to evaluate the subjective wearing comfort of caps from the objective measurement of pressure was developed. Comfortable Fittability Index(C.F.I) and Holding Power(HP) were defined to represent the subjective wearing comfort of caps. As a preliminary step to define the Comfortable Fittability Index(C.F.I), average pressure, pressure distribution, standard deviation of pressure were obtained and subjective sensation were evaluated by wearing caps. Also Holding Power(HP) was estimated from wind tunnel testing. Two sets of caps were evaluated, one set made of elastic fabric(F-caps) and the other set made of non-elastic fabric(S-caps). F-caps begin to be taken off by the higher wind velocity and thus exhibited higher values of Holding Power. On the other hand, F-caps exerted lower average pressure, narrower pressure distribution, smaller standard deviation.

This study evaluates the comfort and suitability of safety clothing. We made three safety clothes 'y', 'lg', 'lgH'. Only 'y' made with fluorescence fabric has passed International Standards (ISO 20471). A wearing test investigated the physiological response and subjective sensations at 30℃ and 50% RH, six men participated. Mean skin temperature and tympanic temperature showed significant difference with experimental course (p<.05). The micro-temperature (Tm) showed significant differences between three garments on the thigh (p<.01). When wearing 'lg', Tm was the highest. Micro-humidity indicated the interaction between clothing and the experimental course on the chest with no significant difference; however, there was a low tendency when wearing 'lgH' after the second half of exercise. The sweat rate indicated a significant difference between 'lg' and 'lgH' at 20 minutes of exercise (p<.05). Three sensations showed significant differences with the time (p<.01), there was also a tendency to feel hotter and more humid when wearing 'lg'. Skin sensation showed significant differences between pre-experiment and post-experiment (p<.05), 'y' was the most preferred. The 'lg' with long-sleeved currently worn in Korea tended to feel hotter, more humid and more uncomfortable than 'y'. It indicates that there is room for improvement in Korean safety clothing.

The purpose of this study is to find fitness of brassiere by means of body measuring value, its variation volume, the evaluation of perceptive image, and the evaluation of the sense of wearing. The results were as follows; 1) According to comparison for body measuring value before and after wearing brassiere, bust point (B.P.) height, lower bust height, upper chest circumference, chest circumference, and bust depth are increased, and lower chest circumference, bust point breadth, shoulder middle point - B.P., B.P. -under bust, and cup horizontal girth are decreased. 2) The difference of variation volume by material is not accepted. The part above $20\%$ at variation rate is under the region of the armpit, that is, the region connected arm from the back. 3) The subjects replied that they wore the brassiere in order to compensate the breast and needed to wear it regardless of thiness and obesity. They wore the brassiere in order to dress themselves in good shape, and felt that it put pressure upon the body, while it had nothing to do with adjusting bodily temperature and gave the sense of security. 4) The estimate of the sense of wearing by material is recognized as the difference of the attention at attentive level $1\%$. The multiple factor analysis of each item in the sense of wearing showed that the items which are explained over $90\%$ by common factors are '1. Unpreasant in touch', '2. The part of edge is haggard', '15. Not to be fit'.

Gaps between the upper edges of brassiere mold cups and the breasts are one of the most serious issues in realizing comfort wearing of commercial brassieres for small-breasted women. The surplus ease amounts causing the fit problem were measured from 3D wearing images of the small-breasted women's brassieres. The effect after the removing the surplus ease amounts from the upper edge of mold cup was approved by subjective wearing evaluation. Since the volume distribution of mold cup can also affect the wearing sensation of brassiere, the subjective wearing sensation was compared for two brassieres of different volume distributions, V_L, of which volume was concentrated at the lower cup, and V_C, which has the thickest part at the nipple. As the results, the suitable sensation for cup volume and the natural wearing silhouette could be accomplished by removing the surplus ease amounts from the upper edge of mold cup to reduce the gaps between brassieres and the breasts, which could be accomplished through an approach reducing the volume near the upper edge of mold brassiere cup and making the volume concentrated at the lower cup. These works provide a useful information on the design of the brassiere mold cups for small-breasted women. Moreover, modeling methods of 3D scan data and 3D printing technique for making more accurate mold cases used in this research can be helpful to develop and evaluate clothing products in future.

Objective: Many caregivers often carry infants using baby carriers until they are approximately 36 months old. The purpose of this study was to compare the muscular activity of the trunk and lower leg muscles during trunk flexion-extension movements in correspondence to various wearing methods of a baby carrier blanket. Design: Cross-sectional study. Methods: Sixteen healthy adult women were to wear baby carrier blankets in five different ways in terms of direction and height, followed by flexion-extension of the trunk. Erector spinae (ES), rectus abdominis, rectus femoris (RF), biceps femoris (BF) muscle activities and triaxial acceleration of trunk were investigated. Results: The front-wearing method of the baby carrier blanket increased the muscular activity of the ES muscle, and wearing the baby carrier blanket at waist height in the same direction was significantly higher than wearing it at pelvic height (p<0.05). As the angle of flexion increased during trunk flexion-extension, the muscle activity of the ES, BF, and the RF increased. There was a greater increase in muscle activity of the ES and the BF during extension compared to flexion (p<0.05). Conclusions: If it is difficult to wear a baby carrier blanket due to lumbar pain, it is recommended to lower the wearing height of the baby carrier to the pelvic level so that the external load can be transferred to the lower extremity. In addition, it appears to be necessary to hold the baby and distribute the load onto the waist through proper body control when performing flexion-extension movements of the trunk. More objective and scientific research that includes various daily tasks and evaluation methods are needed.

The purpose of this study is to evaluate the combination of suit details through visual evaluation which helps compensating the classic style suits-middle aged women's body construct for their more attractive fashion styles. The styles of the evaluated suits are formal and classical. The designs of evaluated suits are manipulated in 40 different kinds by the essential elements such as collars, necklines(tailored collars, soutien collars, stand collars, round necklines, V-necklines, etc.), bottoms(slacks, skirts), pocket (flap pocket, none) and opening(opened, closed). The data evaluated by a multiple ranking test were analyzed by paired t-test, ANOVA and Duncan's multiple raged test. The results are summarized as follows : 1. A middle aged woman on skirts suits look more graceful, more elegant, and a bit more refined than that on slacks suits. 2. A middle aged woman wearing a jacket with flap pockets on looks more balanced, and graceful than when wearing with no pockets. 3. Wearing closed jackets looks more balanced and graceful than on opened jackets. 4. The types of collar·necklines can be called the details which put much influence on Image effects. Putting on tailored collar suits is the most graceful, refined, balanced and harmonious case than any others.
