This study classifies black fashion-mania by each type based on their motivation for wearing black fashion as well as verifies how they express their style. To achieve the objectives of this study, the research questions are as follows. First, the images of black fashion-manias are classified. Second, each type of black fashion enthusiasts' motivations for wearing black fashion are verified. Last, black fashion-mania style are analyzed according to image types. In order to answer the research questions, a literature review and in-depth interviews (total 30 respondents (male 15, female 15) were executed. As a result, black fashion-manias use black fashion for self protection, their self-images such as charismatic professional image, modern sophisticated image, body-conscious sexy image, avant garde image which is an anti-fashion norm and unique image. The strong reason why black fashion-manias insist on black fashion is to 'look cooler'. The expressions could be articulated from sophisticated styling techniques that appear to be undecorated rather than an overt decorated styling. It is helpful information to plan black fashion products and to establish a design direction that requires an understanding of why black fashion is pursued, while promoting an understanding of groups of black fashion-mania.

The current study tests the effect of fashion product knowledge and confidence in fashion coordination on innovative fashion product acceptance, mediated by creative fashion consumer efficacy. Creative fashion consumer efficacy refers to a consumers' belief in the ability to consume fashion products in a creative way. The survey was conducted on 474 people between 20 and 40 years of age in a panel of online survey firms. Data was analyzed using reliability analysis and frequency analysis by SPSS 20.0 along with confirmatory factor analysis and structural equation modeling done by AMOS 20.0. The results reveal that creative fashion consumer efficacy consists of original thinking efficacy, usage expansion efficacy, problem solving efficacy, and method variation efficacy that is consistent with the original structure of creative consumption efficacy. In addition, fashion product knowledge and confidence in fashion coordination do not affect innovative fashion product acceptance. The effects of fashion product knowledge and confidence in fashion coordination on innovative fashion product acceptance are fully mediated through creative fashion consumer efficacy. The results of this study demonstrate that people who are knowledgeable, confident and associated with fashion product consumption can have a high level of creative fashion consumer efficacy that increases innovative fashion product acceptance.

The current status of the curricula of departments related to Clothing & Textiles was checked. The names of colleges and departments affiliated with Clothing & Textiles were also examined. Data on introduction of curricula and subjects disclosed on the website of 60 universities were collected, and the total number of subjects collected was 2,306. As a result, the following conclusions were reached: First, departments related to Clothing & Textiles were the most frequently affiliated with the art/design schools. Depending on the name of the department, the colleges they belong to were different. It was found to be related to the name of the department and the name of the college. Second, According to a survey of the percentage of each major area in the curriculum, the portion of the fashion design area was the highest. The results of checking the composition ratio of the major areas according to the department name showed that there were differences in the curriculum according to the department name. Third, we looked for unusual subjects that were not found in other universities, which could be largely summarized into three: those for characterization, those for preparing for the Fourth Industrial Revolution, and those related to the current situation in the department of Clothing & Textiles. Fourth, we examined subjects related to the Fourth Industrial Revolution, and found that words such as 'sustainable', 'convergence', 'smart', 'knowledge property' and 'computer' were in common. However, the number of subjects was extremely low.

Body positivity has emerged among young social media users with the purpose of enhancing a positive body image. In the social media environment, body positivity is frequently presented in the forms of female models' images and/or words that represent individual attitudes toward the female body. The media effects on female viewers' body image differs based on the viewers' perceptions of their own body size. This experimental study examined how body positivity and types of expression on social media influence women's mood and appearance satisfaction by subjective body size. We randomly assigned to 415 young and middle-aged females to one of six experimental conditions which contained three images and three vignettes, each reflecting non-body positivity, body positivity, and control. We used a 3 (body positivity: non-body positivity vs body positivity vs. control) × 2 (types of body positivity expression on media: images vs vignettes) × 2 (subjective body size: under/normal weight vs overweight/obese) between-subject design. The results of MANCOVA revealed the significant main effects of subjective body size on women's mood and appearance satisfaction. There was a significant interaction effect of body positivity and subjective body size on appearance satisfaction. The stimuli representing body positivity caused positive psychological effects for women who perceive themselves being in the under/normal weight range.

The fashion industry has faced environmental, social, and ethical issues due to increased interest in ethical consumption. Numerous ethical studies have been conducted in the fashion industry. This study looked at the current state of research by year, academic journal, and detail in major related papers published in Scopus, KCI and KCI between 2009 and 2019. Ethical fashion studies began to appear in 2009 and were concentrated in certain academic journals and focused on fashion marketing and fashion design. Topics in ethical fashion were terms such as sustainable, eco-friendly, up-cycling, recycling, eco, zero-waist, and organic. In ethical fashion studies, environmental studies were conducted most often; in addition, the terms used along with ethical fashion tend to be frequently used for each particular major. Looking at key words used in research by period, the study showed that research was most diverse between 2016 and 2019. In particular, environmental and social issues of ethical fashion and convergence with animal protection, new distribution, science and technology sectors were newly added between 2016 and 2019. This study used text mining and network analysis to understand the overall trends of ethical fashion studies in Korea. In conclusion it is important to realize the relationship between the main words along with the current status analysis.

This study examined the relationship between Korean male consumers' perceptions of marketing promotion investment such as advertising expenditure and celebrity endorsement are the brand equity elements. It also compared if there were differences on this research model and two groups that selected Korean or foreign country-of-brand-origin in fashion product purchasing. Online survey responses from 414 Korean men in their 20s-30s were analyzed using confirmatory factor analysis (CFA) and structural equation modeling analysis (SEM). Perceptions of advertising expenditures were found to be positively related to brand association in only the group that selected Korean country-of-brand-origin. The results showed a non-significant effect of perceptions for advertising expenditures on perceived product quality in both groups that selected Korean or foreign country-of-brand-origin. The results indicated that celebrity endorsement had a significant effect on brand association for the two male consumer groups. The results also demonstrated that the relationship of celebrity endorsement and perceived quality was significant in only a group that selected Korean country-of-brand-origin. The results also revealed that the effect of brand association and perceived product quality on brand preference was significant in both male consumer groups. This study has useful managerial implications for enhancing the effectiveness of investment in advertising activities.

This study is to help produce highly comfortable and wearable and footwear based on the establishment of basic data for manufacturing elderly footwear patterns and products. For this, a survey of 207 women in their 20s and 60-70s was conducted to identify the wearing of shoes, inconvenience areas, purchase practices and footwear preferences by age group. The results are as follows. First, the average age of the young female group was 22.5 years old, the elderly female group was 68.8 years old, and the average shoe size was 236.3 mm for the young female group and 238.3 mm for the elderly female group. Second, young women wore shoes for a longer time than elderly women, resulting in swollen and numb legs, hardened soles, uncomfortable toes and sore heels. However, elderly women felt more uncomfortable wearing footwear than young women. They suffered pain in the joint area, heal and toe areas as well as had more toe deformations due to aging. Third, all age groups preferred athletic shoes and loafers as well as purchases from footwear brand stores and department stores. The elderly spent more money on shoes, longer time to buy and valued the feeling of wearing, whereas the young considered design first. Fourth, both age groups prefer low-heels and natural leather, the young preferred to wear various types of shoes; however, the elderly are found to desire shoes that are comfortable and stable in both form and wearing.

Recently, following the commercialization and market entry of smart clothes with diverse functions, smart clothes have been changing from technology-centered products to user-centered products. However, the analysis of consumer demand centered on actual commercialized products is lacking. Therefore, this study classified commercialized smart clothes by function and analyzed the demand and requirements of smart clothes according to sports/outdoor clothes consumption behaviors. As a result, consumers were classified according to their sports/outdoor clothes consumption behaviors into an outdoor leading group with high consumption propensity, an outdoor pursuit group with medium consumption propensity, and an outdoor following group with low consumption propensity. Among the commercialized smart clothes, those with a heartbeat measuring function, those with a heating function, and those with a light-emitting function were presented and demand analysis was conducted. According to the results, the outdoor leading group and the outdoor pursuit group had higher levels of awareness, preference, and purchase intentions than the outdoor following group. In addition, the outdoor leading group showed the highest level of purchase price acceptance while the outdoor following group showed the lowest level of purchase price acceptance. However, this study has a limitation that the acceptance for smart clothes were analyzed with consumers who had experience in sports outdoor clothes consumption. Therefore, in future, studies will be conducted with a wide range of consumers.

This study analyzes changes in the knees, hips, and hip joint length according to the different angles of bending knees by 45°, 90°, and 135° respectively for knees, hips, and the hip joint that have high fracture rates when falling down. The research subjects were 10 elderly women in their 60s (or older) that obtain data collected through direct measurement. For analysis, the study drew a diagram of elongation and shrinkage based on changes and change rate from a straight posture (0°) and conducted a statistical analysis on differences of body surface length by zone according to movements. The more the knees were bent, the vertical surface length in front of the knees, the horizontal surface length above the knee line, the horizontal body surface length below the knee lines on the back, and the vertical surface lengths between front side lines and the side lines increased; however, the vertical surface length on the back decreased. For the hip joint, the difference in the vertical surface length was more distinctive when compared to the horizontal. Finally, the horizontal surface length increased below the hips and the vertical surface length increased in most areas except the sidelines and the front. The result of the change in body surface length according to the movements of this study can be utilized in the development of the motion-variable protector.

We proposed a simple process of fabricating electroconductive textiles by coating conductive polymer PEDOT:PSS (Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)) on biocompatible PLA (Poly Lactic Acid) nanofiber web for application to smart healthcare. Electroconductive textiles were obtained by a drop-coating process using different amounts of PEDOT:PSS solutions., DMSO (dimethyl sulfoxide) was then used as an additive in the post-treatment process to improve conductivity. The surface morphology of the specimens was observed by FE-SEM. The chemical structures of the specimens were characterized using FTIR. The electrical properties (linear and sheet resistance) of the specimens were measured. The effect of the bending angles on the electrical properties was also investigated to confirm their applicability as wearable smart textiles. FE-SEM and FTIR analysis confirmed that the deposition of PEDOT:PSS on the PLA nanofiber web surface was successful. The conductivity of the PEDOT:PSS/PLA nanofiber web was enhanced up to 1.5 ml with an increasing amount of PEDOT:PSS solutions, but there was no significant difference at 2.0 ml. The optimum condition of PEDOT:PSS deposition was established to 1.5 ml. Even when the specimen coated with 1.5 ml was bent every 30°, the change in the electrical resistance values was still low within 3.7 Ω. It confirmed that stable electrical performance was maintained and proved the applicability as a flexible textile sensor.

This study reviews studies that used skin temperature in order to establish an emotion evaluation protocol based on skin temperature for home appliances. A survey of skin temperature evaluation papers was conducted by the following five stages: (1) keyword search, (2) title screening, (3) abstract screening, (4) full paper screening, and (5) relevance evaluation. Selected papers were reviewed for: purpose, recruitment criteria of participants, the number of participants, apparatus, procedure, measures, analysis methods, and major findings. Thermistor sensors and thermography are used for the measurement of skin temperature. Skin temperature sensors are attached to 4 - 10 locations on the body and their mean of skin temperature is calculated by Ramanatan's 4-point or Hardy & Dubois's 7-point method. Semantic differential (SD) method and thermography measuring facial surface temperature have been used for emotion evaluation. The SD method provides a set of adjective pairs related to a product and evaluates changes in emotion from the use of the product. The range of facial surface analyzed is defined in the thermal image and temperature changes before and after the evaluation are analyzed. The evaluation items of home appliances include form, color, material, aesthetics, satisfaction, novelty, convenience, pleasantness, and excellence. Many existing emotion studies using skin temperature do not apply physiological and psychological methods. This study provides basic data to establish a skin temperature and emotion evaluation protocol by examining literature for skin temperature and evaluation of sensitivity.

The purpose of the present study was to explore the most effective body region and cooling temperature to alleviate heat strain of workers in hot environments. We developed liquid cooling hood, vest, sleeves and socks and applied the water temperatures of 10, 15, 20, and 25℃ through the liquid cooling garments in a hot and humid environment (33℃ air temperature and 70% RH air humidity). A healthy young male participated in a total of 16 experimental trials (four cooling garments × four cooling temperatures) with the following protocol: 10-min rest, 40-min exercise on a treadmill and 10-min recovery. The results showed that rectal temperature, mean skin temperature, and ratings of perceived exertion during exercise; heart rate and diastolic blood pressure during recovery; and total sweat rate were lower for the vest condition than other garment conditions(p < .05). However, there was no differences in mean skin temperature among the four cooling garments when we compared the values converted by covering area(%BSA). When we classified the results by cooling temperature, there were no consistent differences in thermoregulatory and cardiovascular responses among the four temperatures, but 25℃ water temperature was evaluated as being the most ineffective cooling temperature in terms of subjective responses. In conclusion, the results indicated that wearing cooling vest with < 20℃ cooling temperature can alleviate heat strain of workers in hot and humid environments. If the peripheral body regions are cooled with liquid cooling garments, larger cooling area with lower cooling temperature than 10℃ would be effective to reduce heat strain of workers. Further studies with a vaild number of subjects are required.
