The aim of this study is to investigate the actual state for the development of the thermally comfortable uniform for workers on a low temperature storage. Observation, interview and survey were executed focusing on the environment, clothing, and human factors which have effects on the comfort of workers. Of 400 distributed, 253 questionnaires were analyzed through descriptives, frequency, ANOVA, t-test, multi-response analysis, correlation analysis with SPSS 12.0. The results are following. Coming and going between a selling area and cold storages, the workers showed to experience a big temperature gap. They indicated to feel cold on face and hands which were not covered by clothing and have got sick because of low temperature. The workers wanted the uniform made of functional fabrics, especially heat insulation fabrics. Female workers rather than male workers, the older, and the longer their working period were, the more uncomfortable they revealed to feel. The workers who works on the daily products part or mainly on the freezer appeared to feel cold more than any other workers. In conclusion, it was found that the uniform which consider steady state and unsteady state heat transfer together must be developed.

Recent advancements in optics technology enable us to realize fast scans of hands using two-dimensional (2D) image scanners. In this paper, we propose an automatic hand measurement system using 2D image scanners for customized glove production. To develop the automatic hand measurement system, firstly hand scanning devices has been constructed. The devices are designed to block external lights and have user interface to guide hand posture during scanning. After hands are scanned, hand contour is extracted using binary image processing, noise elimination and outline tracing. And then, 19 hand landmarks are automatically detected using an automatic hand landmark detection algorithm based on geometric feature analysis. Then, automatic hand measurement program is executed based on the automatically extracted landmarks and measurement algorithms. The automatic hand measurement algorithms have been developed for 18 hand measurements required for custom-made glove pattern making. The program has been coded using the C++ programming language. We have implemented experiments to demonstrate the validity of the system using 11 subjects (8 males, 3 females) by comparing automatic 2D scan measurements with manual measurements. The result shows that the automatic 2D scan measurements are acceptable in the customized glove making industry. Our evaluation results confirm its effectiveness and robustness.

Poly(m-phenyleneisophthalamide), m-aramid has no adjacent $\alpha$-hydrogen of a nitrogen-halogen bond causes dehydrohalogenation. This fact proposes that m-aramid is one of good antimicrobial precursors. To enhance the surface area of m-aramid, electrospinning was employed. Scanning electron microscopy(SEM) was conducted to inspect the morphology change of m-aramid. The surface area of regular and electrospun m-aramid was calculated. Swatch test was applied to measure antimicrobial activity of the samples. The results showed that within 10 min contact time the electrospun m-aramid inactivated Escherichia coli KCTC 1039 (Gram-negative bacteria) with 8 log reductions.

This research investigated the physical properties of PET coolness filaments and their knitted fabrics including dyeing characteristics of these knitted fabrics according to the different dyeing time and temperature. The coolness filament(S) with non-circular cross-section and hydrophilic property was spun and another commercialized coolness(A) and regular(R) PET filaments were prepared for comparing coolness and another physical properties. Qmax of coolness knitted fabric made with S filament was higher than that of R-PET filament, and the maximum value of Qmax of S knitted fabric was shown at the dyeing conditions of temperature, $110^{\circ}C$ with 30 min. or 40min. It was shown that hand of S knitted fabric was a little harsh comparing to A and regular knit specimens, but shape retention and wearing performance of garment made with S knit specimen were estimated as good owing to high bending and shear rigidity. K/S of S knitted fabric was higher than those of regular PET and A knit specimens. Dyeing fastness of coolness knitted fabric showed between 4th and 5th grade.

The purpose of this study was to explore global consumer behavior with fashion products, Korean fashion products, and Korean traditional fashion products (i.e., Han-Bok). Clothing selection criteria for fashion products and Korean fashion products were included as major constructs far the comparison among global consumers based on their nationality. Other consumer behavior variables were shopping place, buying frequency, purchase experience/plan, preferred brand, purchase items, information source, purchasing usage, and the product evaluation of Hanbok. A convenience sample of 236 global consumers was selected for this study. A questionnaire was pilot tested, and the revised questionnaire was used for the interview survey. Descriptive statistics and ANOVA were used for data analysis. Various nationality were existed such as Europe, North America, Japan, China, South East Asia. The results indicated that the most important criteria for fashion buying were design, fit, and size in order. Fit, size, and color item from buying criteria were significantly different among global consumers by nationality. Country of origin was found as less important factor among global consumers. Department store was most favorable shopping place, and once a month is the most mentioned category in buying frequency. Preferred brands were Levi's, Polo, Gucci, and Prada, etc. Secondly, regarding the evaluation of Korean fashion products, textile quality was highly evaluated. Significant difference except design/style category were existed among global consumers by nationality. Thirdly, regarding the evaluation of Hanbok, the product evaluation of Hanbok highly represented as special event clothing, unique image, beautiful details and oriental beauty in order. Significant difference in good quality of textiles, oriental beauty, coordination with good colors and fabrics, beautiful details and unique style and design were existed among global consumers by nationality. Managerial implications were discussed.

This study investigates the effect of recovery elasticity of beauty college students on university life adaptation during COVID-19. Further, the mediating effect of grit in relation to recovery elasticity and university life adaptation is analyzed. Survey data of 223 students (female: 192; male: 31) were collected for multiple and intermediate regression analyses using SPSS 24.0. The results reveal a static correlation between the lower factors of resilience, glittery, and adaptation to college life and that the resilience of junior college students in the beauty department had a static effect on grit and their adaptation to college life. Passion, a subordinate factor of grit, is mediated by the effect of grit on the relationship between resilience and adaptation to university life. However, perseverance, another subordinate factor of grit, did not have any such mediating effect. These results confirm the importance of grit, particularly passion, for resilience and adaptation to college life. It was confirmed that resilience was due to college life adaptation of beauty department students, and it was confirmed that passion, a sub-factor of grit, also had a mediating effect. Therefore, it is judged that resilience induces physical and mental adaptation, interpersonal adaptation, and academic adaptation necessary for college life, and works in many ways to improve the quality of life of beauty department junior college students. Instructors should consider developing educational programs for improving recovery elasticity and grit to help students better adapt to university life.

The purpose of this study was to obtain drape information and objective texture of fabrics easily and quickly by using a constructed fabric database. For the construction of the fabric database, 287 woven fabrics were examined by using the CLO fabric kit, KES-FB system, and drape test system. The k-means cluster analysis method was used to classify the fabrics into 7 grades. After correlation analysis of the fabric properties for each experiment, similar properties of the CLO fabric kit and KES-FB system were chosen, which were then designed to extract similar fabrics from the database. It was confirmed that inferring the drape information and objective hand feeling of fabrics was to some extent possible by extracting similar fabrics from the database. In this study, the primary hand and total hand value(THV) of KES-FB system, which was constructed by Kawabata and other experiments, were used to quantify the objective hand feeling, because they are the most widely used. However, these standards can be changed over time; in order to be applied within the clothing industry, these standards may have to be changed to some extent. Moreover, it is notable that although objective hand feeling cannot be expressed in the 3D virtual costume program, it can be easily derived from the constructed database. Additionally, it is expected that the existing 3D virtual costume program will express the costumes more realistically by improving these results.

This study aimed to investigate the effects of silk fibroin on bone metabolism in ovariectomized rats. A total of 30 Sprague-Dawley rats were randomized into sham-operated (SHAM), ovariectomized control (OVX), alendronate (OVX+ALEN, 10 mg/kg body weight/d), low silk fibroin (OVX+SF100, 100 mg/kg body weight/d), and high silk fibroin (OVX+SF300, 300 mg/kg body weight/d) groups. All the rats were fed by gavage for 12 wk. At the end of 12 wk, blood and urine were collected for analysis of bone turnover markers, and bone mineral density (BMD) was measured by micro-computed tomography. The results show that the OVX group (p < 0.05) displayed the highest mean body weight gain. Among the five groups, serum levels of bone alkaline phosphatase (ALP) and urine levels of deoxypyridinoline (DPD) were highest in the OVX group (p < 0.05). Bone ALP levels in the ALEN group were significantly lower than that of the silk-treated groups. On the other hand, DPD levels were not significantly different between the ALEN and silk-fibroin-treated groups (p < 0.05). The trabecular BMD was significantly higher in the ALEN and silk-treated groups compared to the OVX group (p < 0.05). In conclusion, this study showed that silk fibroin has similar effects as alendronate, which is used in osteoporosis medication. Therefore silk fibroin might be a new candidate for the prevention and treatment of osteoporosis in patients.

As a major obstacle to active online purchase at the level of consumer in China, distrust is raised in this study. Most of previous studies showed that trust is a major variable to cause a relational unity between company and consumer, on the other hand, this study attempts to show that according to the two dimensional point of view regarding trust each dimension of both trust and distrust distinctly contributes to marketing achievement. Interaction, perceived popularity, information usefulness, perceived security risk and perceived dealing risk were created as preceding variable, trust and distrust were constituted as parameter and relation absorption and purchase intention as consequential variable. These variables were analyzed with structural equation modeling (SEM) in LISREL 8.3 program. The results for this study are as follows. First, relation between exchange actors in marketing is divided into two concepts of trust and distrust differently from the previous studies. On the assumption that trust and distrust might exist simultaneously and they would distinctly have an influence on marketing consequency such as relation absorption and repurchase intention, it is identified that trust and distrust are a different dimension in online context. Second, the formative factor of online trust-distrust is identified and it is shown what relationship between internet shopping mall and relation absorption and foregoing purchase intention resulting from online trust-distrust exists. Third, it is shown that in online context the formative factor of online trust-distrust is distinctly contributed to relation absorption and repurchase intention. It is suggested that trust needs to be managed two-dimensionally separating from trust and distrust. Fourth, it is shown that both trust and distrust factor in terms of relation absorption and repurchase intention of consumer in internet shopping mall are significant variables. Trust is linked with repurchase intention through relation absorption, however, distrust is not directly linked with repurchase intention through relation absorption. Thus, the ripple effect of distrust appears to be much higher than that of trust.
