Smart clothing represents the future of both the textile/clothing industry and electronic industry and has an effort to make electronic devices a genuine part of our daily life. The researches about technologies innovation and application of smart clothing can be found in previous studies. But consumer researches about perception or attitude toward smart clothing can be hardly found. Therefore, we proposed a conceptual framework that explores the impact of perceived risks on perceived attributes to adopt smart clothing. In addition, we compared differences of this framework among three counties. Korea, U.S. and Spain. Based on the literature review and hypotheses development, a research model was constructed. After data analysis using Amos 7.0, the results can be concluded as following: First, the influences of psychological risk among Korea, U.S. and Spain are same. Psychological risk has negative effect on relative advantage and complexity, but has positive effect on trialability. Second, loss risk was found to have nothing to do with relative advantage. But it negatively influences complexity for Korean consumers and positively influences trialability for both Korean and American consumers. Third, the influences of performance risk for different consumers are different. At last, based on our discussion, some implications were also concluded.

In this study, electroconductive textiles were developed by screen-printing technology using a complex solution of PEDOT:PSS/AgNW on a polylactic acid nanofiber web. A performance evaluation was then conducted to utilize this electroconductive textile as a signal transmission line. To obtain highly conductive electroconductive textiles, this study sought to determine the optimal mixing ratio of PEDOT:PSS/AgNW. Sheet resistance was measured to evaluate the electrical properties of electroconductive textiles, Finite element-scanning electron microscopy images were then used to examine surface properties, and Fourier transform-infrared analysis was performed to evaluate chemical properties. The signal waveform characteristics of the electroconductive textile were observed using a signal generator and an oscilloscope. Radio-frequency characteristics were then evaluated to confirm frequency range, and bending tests were conducted to evaluate durability. The signal transmission lines produced in this study had a sheet resistance value of 3.30 ?/sq, and signal transmission performance was evaluated to observe that the input value of the voltage was nearly identical to the output value. In addition, S21 analysis confirmed that it was available in the frequency domain up to 35 MHz. The performances of the transmission lines were maintained after 100, 200, 500, and 1,000 repeated bending tests, and sufficient durability was confirmed.

The objective of this study is to investigate the intention to adopt smart wear, based on extended UTAUT model. We examined the effects of performance expectancy (PE), effort expectancy (EE), hedonic motivation (HE), social influence (SI), facilitating conditions (FC), and price value (PV) on the intended adoption of smart watch and smart shoes, respectively. In addition, moderating effects of gender, age, and innovation resistance were examined. An online survey was conducted, comprised of 2030 consumers who were aware of smart watch or smart shoes. In total, 393 responses were analyzed. About 50.4% were male, and 44.8% were in their 20's. An exploratory factor analysis generated five factors - PE & HM, EE, SI, FC, and PV- which were employed as independent variables in the multiple regression models. PE & HM, PV, and SI influenced on the intention to use both smart devices. FC showed the significant effect only on the intention to adopt the smart watch. In terms of gender differences, SI and PV were the important predictors of the intention to adopt the smart watch in the female group only. With respect to age difference, SI was very effective in explaining the intention of individuals in their 30's to adopt smart wear. Among the low innovation resistance group, SI was significant predictor, while PE & HE and PV were significant among the high resistance group. The findings provide useful information about the possibility of the adoption of smart wear, and new insight into market segmentation.

In CPB(Cold-Pad-Batch) dyeing, the rubber of the padder roll is influenced by the heat, chemical and mechanical influences and thus aging of the padder roll rubber occurs. This study presents an accelerated thermal aging test of the CPB padder roll rubber with strong alkali conditions. Using Arrhenius formula of the various property values for the various aging temperatures($80^{\circ}C$, $90^{\circ}C$, $100^{\circ}C$) of the padder roll, the accelerated life predictions could be calculated. The threshold value of the property was set at different values. The hardness was set at the point where 5% degradation occurs based on the actual use conditions, and the tensile strength was set at the point where 50% degradation occurs based on the general life prediction standards. From the results of the different physical properties at differing temperatures, the Arrhenius plot could be obtained. Through the usage of the Arrhenius Equation, significant duration expectation could be predicted, and the chemical aging behavior of the CPB padder roll could be found at the arbitrary and actual temperatures.

The number of elderly citizens has risen in Korea and resulted in an aging society. Correspondingly, the social interest in the aging population has escalated immensely; however, research or product development on the quality of life for seniors has shortcomings. Healthcare smart clothing is required to help the elderly with changes and weaknesses that follow aging; however, there is unfortunately insufficient amounts available. This study explores the feasibilities of smart clothing for seniors based on a universal design. Based on previous research, we analyzed the universal design theory, body shape characteristics and design requirements for seniors, and heart rate measurement method. The design is different according to body shape and body shape is different between sex, age, and body race; therefore, subjects were limited to 70-74 year old Korean males in this study. This study proposes a guideline for heart rate sensing clothing that satisfies the 'universal design' aspects as well as the functionality of heart sensing, senior's physical characteristics and needs. It has broadened the range of smart clothing, which was once limited to the younger generation and provided a foundation for the development of specialized smart clothing for seniors.

Smart photonic clothing integrates light emitting technology inside and outside of the garment and integrates it as a fashion product. It expresses digital color that radiates light outside the body that expands the functionality of the clothing as well as makes new and various attempts visually. It is also is gradually expanding into a new area of fashion. LED, one of the digital color output devices, is a light emitting device that is suitable for presenting consumer customized designs in that the patterns and colors of clothes can be modified as desired by utilizing computer technology such as program coding. LED technology that can realize various digital colors is actively applied in various industrial design fields, but there are few previous studies on smart clothes using LED color in Korean fashion fields. Therefore, this study develops a prototype of a customized LED smart photonic garment that allows the user to directly participate in the color implementation of clothing and select a digital color suitable for the desired function. The LED module was designed to be detachable from clothing and made using a 256-pixel LED matrix. Various coding patterns of the LED were designed using the coding change of Arduino program.

Recent advances in electronic technology have engendered a need for research on the use of smart materials in clothing. Electro-conductive fibers are expected to be a crucial element of wearable devices. Therefore, in this study, we have attempted to develop electro-conductive threads and cables using silver nanowires. Based on the characteristics of silver nanowire, in which electro-conductivity can be imparted via heat treatment, we prepared conductive threads by coating nylon yarn with silver nanowires and curing at temperatures of 140℃, 150℃, and 160℃. Conductive threads cured at 140℃ had the highest conductivity, followed by threads cured at 160℃ and 150℃ respectively. The order of the electrical conductivity of the threads after tensile testing was consistent with the original order of the conductivity of the threads. When we evaluated the sensing performance of electro-conductive cables fabricated from these threads, the cables manufactured from threads cured at 140℃ and 160℃ were found to function normally within temperature and humidity sensors. All the cables operated normally in illuminance and electrocardiogram sensors. Thus, we believe that threads made of silver nanowire have sufficient electrical conductivity to be utilized as wearable sensors.

This study aims to develop a smart uniform with embedded luminescence for street cleaners to enhance visibility, safety, and long-term usability, informed by real users' opinions. It employed mixed-methods research comprising three phases: first, a pre-interview to identify existing problems; second, experiments to evaluate the visibility and durability of the technology embedded in smart uniforms during machine washing; and third, a post-survey and observation to assess user satisfaction regarding safety, long-term usability, and aesthetic aspects. Prototypes were developed to evaluate long-term usability and safety based on users' opinions. The findings indicated users desired long-term usage without the need for additional wear and highlighted concerns about the glare from light-emitting devices. The developed prototypes demonstrated long-term usability, remaining functional after more than 25 machine washes without reducing brightness or structural integrity. Regarding participant satisfaction, 83.5% of users were satisfied with the design, both aesthetically and functionally. This study offers a viable approach to developing user-centered designs incorporating light-emitting devices, which enhance visibility and provide aesthetic satisfaction while ensuring long-term usability. The results hold significant implications for future design research focused on vulnerable populations, emphasizing integrated satisfaction in terms of safety and long-term usability.

This study aimed to analyze consumers' acceptance of sports applications and smart sportswear to better design technology-enhanced walking exercise wear for the Baby Boomer generation based on their cohort characteristics. A questionnaire with items related to acceptance of existing smart sportswear design, functionality, and usability as well as existing sports application design, functionality, and usability was sent to consumers aged 50-65. Of 163 questionnaires distributed, 150 were used for analysis. The results showed that middle-aged consumers were aware of smart sportswear's functional stability, but were concerned about care, durability, and convenience. Middle-aged consumers were also aware of sports applications as educational functions for obtaining new information. Additionally, they found sports applications to have lower perceived convenience and accessibility relative to the young generation, highlighting the need for simple instructions and explanations for sports application planning. Based on these results, we propose "Everyday design for general sportswear," "Functions based on consumer's preference," "Enhanced design for durability and management convenience" for designing and planning walking exercise wear for middle-aged consumers, and "Convenient application organization" and "Educational exercise contents" for application planning for walking exercises.
