It is not clear to assume the history of dyeing by persimmon juice without an early knowledge of an accurate record. However, the beginning of persimmon dyeing in Korea is estimated to be around the $13^th$-$14^th$ century, even though there are no supporting records. On the other hand, there are definite records of persimmon dyeing in Japan from around the 17th century. Persimmon juice was originally used for fishing tools in both Korea and Japan, but upon entering the Modern Era it eventually transfigured into a dye for fabric. In Korea, persimmon-dyed fabrics were used for traditional clothing until it also became a popular choice for modern clothes in the 1990s. In Japan, persimmon juice was originally used for varnishing surfaces of household items, but it recently became a material for arts, crafts, and even apparels. The main difference between persimmon dyeing of the two countries is the presence and absence of the fermentation process. In Korea, persimmons are picked and water is immediately added to its juice to produce the dye. In contrast, Japan produces a fermented persimmon dye. As a result, in Korea the dye can not be preserved for long periods, whilst in Japan it is matured in the storage for 2-3 years. Today's pursuit of eco-friendliness and wellness has prompted an inclination towards natural material clothes. Therefore, it is necessary for both countries to push scientific research into improving the storage methods and colorfastness of persimmon-dyed products for the increase of use consumption in other areas of persimmon and arrowroot dyed fabrics, and the development of environment friendly materials.

The purpose of the present study was to suggest the design requirements for Korean naval duty uniforms by evaluating the physiological and psychological comfort while wearing the uniforms. Two sets of wear trials were conducted with summer uniforms(eight young males) and winter uniforms(seven other young males). The summer wear trial consisted of 10-min rest, 60-min exercise, and 10-min recovery at an air temperature($T_{air} $) of $33^{\circ}C$ and 62%RH, followed by 10-min recovery at a $T_{air} $ of $23^{\circ}C$ and 64%RH(total 90 min). The winter wear trial consisted of 20-min rest at $T_{air} $ $20^{\circ}C$ and 55%RH, 25-min rest, 30-min exercise, and 35-min recovery at a $T_{air} $ of 0oC and 43%RH(total 110 min). Rectal and seven skin temperatures, clothing microclimate, heart rate, oxygen consumption, total sweat rate, and subjective perceptions were measured during the wear trials. By evaluating the experimental results from the wear trials, we extracted the following psycho-physiological design requirements to improve the current Korean naval uniforms: (1) It is important to maintain the skin temperatures within their comfort range, which depends on the body region (higher than $30^{\circ}C$ in winter, but less than $35^{\circ}C$ in summer). (2) In summer, the feet should be protected from the high heat of the ship floor surface. (3) In summer, sweat from the back should be sufficiently absorbed and allowed to dry quickly.

Due to the paradigm shift in fashion industry, its contribution to social activities and social enterprises' practice of ethical fashion has been on the rise lately. The surveillance and regulations of international community have increased in light of the betterment of working conditions and protection of the rights, and corporate social responsibility has been emphasized through consumers' interest in ethical consumption. In this regard, the fashion social enterprises' responsible and ethical management can both boost the trust in business and value-added. The study aims to propose feasible methods by exploring ways to induce support from central and local governments, which will lead to the activation of future fashion social enterprises and paradigms shift of consumers's perception and value. The sustainability of social enterprises requires management line or policies that consider social, environmental, economic, and political aspects of virtuous cycle, differentiated internally or externally. Fashion social enterprises also need ethic management and social responsibility management that are distinctive from general fashion enterprises. Thus, they will not be sustainable or differentiated unless entrepreneurial faith and role is not clear. Education and continuous promotion including upcycling are critical to build consumer base as they can make consumers spend ethically and recognize social enterprises. In addition, social education and public relations need to take place in order to internalize consumer pattern. The goal of sustainable corporate social activity is to change the awareness and become social investment that returns some profits to the society as members in line with reviewing corporate image. This can lead to establishing the foundation of securing a big comsumer market and winning the trust of the consumer's through corporate social responsibility and investment.

This study groups the life content of adolescents according to their time spent during the week and compares their internet use. The data were collected from 2210 middle and high school students, including their life content and hours, and various internet factors such as self-evaluated internet addiction, internet support, internet experience, chatting subjects and the type of internet service. Adolescents were divided into five groups: TV-oriented group, computer-oriented group, peer-oriented group, self-study group and extracurricular institution group. The purpose of internet use, internet experience, chatting subjects, negative aspects of internet and internet addiction were different by adolescents' group type. The peer-oriented group had the highest real self image as opposed to the cyber self image and trusted other's words on the internet. The TV-oriented group had the lowest trust in the internet. The computer-oriented group received the highest internet support and internet experiences, but didn't use the internet for the purpose of information search. The self-study and extra-curricular institution groups used the internet the least, used it to solve stress and were interested in school circles on the internet.

Despite the economic downturn, the amount of clothing being discarded is increasing due to the fast fashion. The purpose of this study is to propose a fashion sharing service development to settle the rational consumption culture along with the abandoned clothes problem. Shared fashion rental service has attracted as a solution to environmental problems not only when clothes are incinerated but also in manufacturing process, but there is a lack of precedent research. Therefore, this study is meaningful in that it has developed two development plans based on the results of analysis of service case based on three factors by Rachel Botsman. First, active community development. Second, it is the creation of goods through activation of the shared economy. In this study, there are limitations that can't be proved through actual application, so more research is needed through empirical studies on actual users in the future.

This study explores the effects of facemasks on respiratory, thermoregulatory, cardiovascular responses during exercise on a treadmill and at rest. Five male subjects (25.8 ± 0.8 y, 171.8 ± 9.2 cm in height, 79.8 ± 28.1 kg in weight) participated in the following five experimental conditions: no mask, KF80, KF94, KF99, and N95. Inhalation resistance was ranked as KF80 < KF94 < N95 < KF99 and dead space inside a mask was ranked as KF80 = KF94 < N95 < KF99. The surface area covered by a mask was on average 1.1% of the total body surface area. The results showed no significant differences in body core temperature, oxygen consumption (VO2), carbon dioxide production (VCO2), heart rate or subjective perception among the five experimental conditions; however, cheek temperature, respiratory ventilation and blood pressure were greater for KF80 or KF94 conditions when compared to KF99 or N95 conditions (p<0.05). The differences among mask conditions are attributed to the dead space or specific designs (cup type vs pleats type) rather than the filtration level. In addition, the results suggest that improving mask design can help mitigate respiratory resistance from increased filtration.

Objectives: The unsafe use of pesticides in agriculture represents a major hazard to human health. This study was conducted to investigate the association between pesticide exposure and health symptoms among chili farmers in northeast Thailand. Methods: This cross-sectional analytic study included 141 chili farmers in Sakon Nakhon Province, in northeast Thailand. Data regarding health symptoms were gathered using a self-report questionnaire. A medical technician tested blood cholinesterase activity using an erythrocyte method, and an occupational medicine specialist at Ramathibodi Hospital in Bangkok, Thailand reviewed the results. Associations between personal characteristics, pesticide exposure factors, and health symptoms were analyzed using multiple logistic regression. Results: Of the 141 chili farmers studied, 66.7% experienced pesticide poisoning, as indicated by below-normal cholinesterase levels. Fatigue was the most frequently reported symptom associated with pesticide exposure, affecting 37.6% of participants. This was followed by nausea and vomiting (31.9%), dizziness (14.9%), and dry throat (14.9%). Multivariate logistic regression analysis revealed that several factors were significantly associated with adverse symptoms: amount of work experience, volume of pesticides used, use of chemical pesticides, use of leaking containers during spraying, direct pesticide exposure while working, contact with pesticide-soaked clothing, consumption of food and drinks in the fields, and blood cholinesterase level indicating risk. Conclusions: This study suggests potential health risks for chili farmers stemming from exposure to and contamination by pesticides used in agricultural practices. To mitigate these risks, it is essential to supply personal protective equipment and to implement educational programs aimed at improving protective behaviors among farmers.

Virtual influencers, who are emerging as new players in digital marketing, impact consumers' purchase intentions. They promote positive perceptions and mimetic consumption of specific brands or products through interactions with followers. Therefore, this study aims to examine the effect of the characteristics of virtual influencers on the purchase intention for fashion products through the consumers' mimetic desire. As characteristics of virtual influencers, five factors were set: reality, attractiveness, professionalism, trustworthiness, and curiosity. Data for analysis were collected through an online questionnaire from the 8th to the 15th of August 2023, and 268 data points in total were analyzed using SPSS and Process Macro 4.3. The results of the study showed that the characteristics of virtual influencers all positively affected mimetic desire and purchase intention for fashion products. Moreover, it was found that mimetic desire has a mediating effect between the five characteristics of virtual influencers and the purchase intention for fashion products. Mimetic desire fully mediates the relationship between reality and the intention to purchase fashion products, and partially mediates the relationship between attractiveness, professionalism, trustworthiness, and curiosity and the purchase intention for fashion products. These findings further enhance the understanding of the relationship between virtual influencers and consumer behavior and identify the relationship between virtual influencers, mimetic desire, and fashion product purchase intentions. Consequently, leveraging virtual influencers strategically in digital marketing, the fashion industry can amplify positive brand perceptions, drive consumer engagement, and ultimately foster increased purchase intent.

The changing media landscape has diversified how and what is discussed about fashion. This study aims to examine expert discussions about fashion shows on social media from the perspective of fashion criticism. To achieve this goal objectively, a text mining program, Leximancer, was used. In total, 58 videos were collected from the panel discussion section of Showstudio from S/S 21 to S/S 24, and the results of text mining on 24,080 collected texts after refinement are detailed here. First, the researchers examined the frequency of keywords by season. This revealed that in 2021-2022, digital transformation, diversity, and fashion films are now commonly used to promote fashion collections, often replacing traditional catwalk shows. From 2023, sustainability and virtuality appeared more frequently, and fashion brands focused on storytelling to communicate seasonal concepts. In S/S 2024, the rise of luxury brand keywords and an increased focus on consumption has been evident. This suggests that it is influenced by social and cultural phenomena. Second, the overall keywords were analyzed and categorized into five concepts: formal descriptions and explanations of the collection's outfits, sociocultural evaluations of fashion shows and designers, assessments of the commerciality and sustainability of the current fashion industry, interpretations of fashion presentations, and discussions of the role of fashion shows in the future. The significance of this study lies in its identification of the specificity of contemporary fashion criticism and its objective approach to critical research.
