Despite consumers' increasing awareness and interests in innovative wearable devices, the sales growth has been stagnant. To analyze this phenomenon, we investigate consumer preferences for various innovative features embedded in wearable devices. Conducting conjoint analysis on smartwatches, we empirically show that the curse of innovation can occur when the consumer's expected utility from the smartwatch falls short of his/her psychological cost associated with behavior change from smartwatch usage. Therefore, our findings provide managerial implications on the R&D strategy for new technologies and more importantly on the marketing strategy easing consumers' resistance to highly innovative products.

Republic of Korea officially announced its mid term reduction target which reduce about 30% of BAU GHG emission by 2020 in the 15th meeting of UNFCCC(COP 15) held in Copenhagen, Denmark 2009. To achieve this goal, it is necessary to understand the serious of climate change and take part in GHG reduction not only industry but also the nation. However, such positive participation in green life which may cause inconvenient of the life of the people. It should be accomplished with providing reliable information. This study suggests the scientific potentialities of GHG emission by guideline on low carbon life and green life to form and change a lifestyle suitable for coping with climate change. And also, this study quantitate the GHG reduction which may reduce demand for air conditioning by cool biz and warm biz. In Korea, this campaign has become known as 'CoolMaebsi' by Ministry of Environmental of Korea. 'CoolMaebsi' is a compound word of 'Cool' which means feel refreshed, and 'Maebsi' is a Korean word which means attire. Though this campaign is effective and significant to reduce the GHG emission yet there were no study on quantitative analysis. Therefore this study calculated reduced energy consumption and potential GHG emission by measuring variation of skin temperature. As the result, wearing warm biz and cool biz have an effect of reducing not only the energy consumption but also GHG emission. To achieve the low carbon society, it is necessary to improve the energy saving system and introduce the policy which guide to change a life style.

The global COVID-19 pandemic has transformed face masks from situational accessories to indispensable items in daily life, prompting a shift in public perception and behavior. While the relaxation of mandatory mask-wearing regulations is underway, a significant number of individuals continue to embrace face masks, turning them into a form of personal expression and identity. This phenomenon has given rise to the Fashion Mask industry, characterized by unique designs and colors, experiencing rapid growth in the market. However, existing research on masks is predominantly focused on their efficacy in preventing infection or exploring attitudes during the pandemic, leaving a gap in understanding consumer preferences for mask design. We address this gap by investigating consumer perceptions and preferences for two prevalent mask designs-horizontal fold flat masks and vertical fold flat masks. Through a comprehensive approach involving surveys and eye-tracking experiments, we aim to unravel the subtle differences in how consumers perceive these designs. Our research questions focus on determining which design is more appealing and exploring the reasons behind any observed differences. The study's findings reveal a clear preference for vertical fold flat masks, which are not only preferred but also perceived as unique, sophisticated, three-dimensional, and lively. The eye-tracking analysis provides insights into the visual attention patterns associated with mask designs, highlighting the pivotal role of the fold line in influencing these patterns. This research contributes to the evolving understanding of masks as a fashion statement and provides valuable insights for manufacturers and marketers in the Fashion Mask industry. The results have implications beyond the pandemic, emphasizing the importance of design elements in sustaining consumer interest in face masks.

Movements of the lower limb are important for normal walking and smooth oscillation of the center of gravity. The ankle rotations such as dorsi-flexion, plantar-flexion, inversion and eversion allows the foot to accommodate to ground during level ground walking. Current below knee (B/K) prostheses are used for replacing amputated ankle, and make it possible for amputees to walk again. However, most of amputees with B/K prostheses often experience a loss of terrain adaptability as well as stability because of limited ankle rotation. This study is focused on the development of multi-rotational prosthetic foot for lower limb amputee. Our prosthesis is possible for amputees to easily walk in level ground by rotating ankle joint in sagittal plane and adapt to the abnormal terrain with ankle rotation in coronal plane. The resistance of ankle joint in the direction of dorsi/plantar-flexion can be manually regulated by hydraulic damper with controllable nozzle. Furthermore, double layered rubber induce the prosthesis adapt to irregular ground by tilting itself in direction of eversion and inversion. The experimental results highlights the potential that our prosthesis induce a normal gait for below knee amputee.

The purpose of this study was to identify differences or similarities across the ensembles of 2006 F/W fashion trends in the big fashion centers such as Paris, London, New York, and Seoul, by street fashion research. The study focuses on understanding of localized fashion trend in the marketplace. We used photograph observation and analyzed data by SPSS program. We found there is a significant difference in winter outfits at these different global fashion mega cities. Most Korean women were wearing light colored outer jackets and blue jeans were dominant style for pants. The majority of Paris/London, New York and Seoul people on the street were wearing wool/wool like coat. Padded coats were worn more by New Yorkers than by people in Seoul. For the bottom, there is a similarity between Paris/London, and New York City, in that skinny pants were popular. Koreans were wearing skinny pants mostly, but the percentage of mini skirts/shorts was also higher than any other cities. We found that the cross-cultural fashion mega trend is similar in clusters, but there is a slight difference of trend in clothing color, style and design details, and accessories by localized fashion cities. Not only direct observation but also identification of cultural characteristics and consumer behavior through the years will bring much more contributions to apparel industries.

In this study, we investigated which message provider is effective in a virtual reality (VR) environment for individuals with different needs with regard to affect (need for affect [NFA]) and cognition (need for cognition [NFC]). According to Haddock et al (2008), individuals with high NFA were more influenced to change their behavior by the emotional aspects of a message, whereas individuals with high NFC were more influenced by the cognitive aspects of the same message. We hypothesized that individual differences in needs could affect not only receipt of the message but also the acceptability of the message provider. For example, someone with high NFA might accept messages more easily from an acquaintance than from experts. In the VR environment, the appearance of the message provider could be manipulated in a way that makes him or her more familiar to the person receiving the message. Accordingly, in order to promote the effectiveness of message providers in a VR environment according to the individual difference in needs, we measured the level of the preference and self-efficacy according to needs (NFA or NFC), type of message provider (expert, significant other, or other), and VR device (text or VR). Contrary to what we expected, the results showed that there was no matching effect between the needs and the message provider. However, we found that level of preference and self-efficacy were significantly high when a VR device was worn only by participants with high NFA. This result suggests that a VR environment is more suitable for providing health advice to people with high NFA. In addition, the novelty of this study is that we tried to find the tailored message provider on health advice in VR environment and it is in the early stage of the research.

In this study, we propose the core factors and application of asymmetric virtual reality(VR) content in which head-mounted display(HMD) user and Non-HMD users can work together in a co-located space that can lead to various experiences and high presence. The core of the proposed asymmetric VR content is that all users are immersed in VR and participate in new experiences by reflecting widely a range of users' participation and environments, regardless of whether or not users wear the HMD. For this purpose, this study defines the role relationships between HMD user and Non-HMD users, the viewpoints provided to users, and the speech communication structure available among users. Based on this, we verified the core factors through the process of producing assistive asymmetric VR content and cooperative asymmetric VR content directly. Finally, we conducted a survey to examine the users' presence and their experience of the proposed asymmetric VR content and to analyze the application method. As a result, it was confirmed that if the purpose of asymmetric VR content and core factors between the two types of users are clearly distinguished and defined, the independent experience presented by the VR content together with perceived presence can provide a satisfactory experience to all users.

This is the result of the comparison of the number of jeans, colors, images, opinions when it was purchased, shapes according to the gender of persons in jeans. According to the gender, male students had 1.64 jeans(46.3%) and female students had 2.09 jeans(53.7%) on the average. Male students selected colors of jeans which they don't have, but want to wear once in the order of blue(3.7%), red(21.0%), white(24.1%), black(25.6%), and others(25.6%). Female students selected colors in the order of blue(3.2%), black(15.6%), red(24.8%), white(27.7%) and others(25.6%). In case of the general image about jeans, male students thought the jeans as masculine(1.2%), sexy(3.1%), unisexual(3.2%), active(23.6%), young(29.8%), and comfortable(36.5%) and female students thought it as masculine(0.3%), sexy(3.5%), unisexual(10.4%), young(21.9%), comfortable(28.1%) and active(35.8%). Male students considered torn or holed jeans ill-mannered(10.7%), delinquent, (20.7%)trendy(21.0%), comfortable(22.9%), and dandy(24.7%). Female students think it ill-mannered(3.4%), delinquent7.1%, trendy(17.4%), comfortable(21.1%), and dandy(50.9%). When they purchase jeans, male students choose according to trends(17.9%), don't consider design(19.5%) and look for their own styles(62.6%), female students didn't consider design(5.2%), choose according to trends(22.0%), and look for their own styles(72.5%). The designs of jeans which they usually wear were bell bottom(1.5%), wide-shaped(7.4%), baggy(17.5%), straight-shaped(73.6%) in case of male students. on the other hand, in case of female students, baggy(10.2%), wide-shaped(11.0%), bell bottom(17.0%), and straight-shaped(61.8%). The designs of jeans which they didn't have but want to wear once are wide-shaped(10.1%), bell bottom(13.2%), baggy(20.9%), and straight-shaped(55.2%) in case of male students. On the other hand, females students want to wear baggy(11.6%), wide-shaped(15.0%), straight-shaped(27.6%), and bell bottom(45.8%). The above-mentioned findings illustrated that both male and female students regarded blue as the original color of jeans, but they wanted to wear jeans in colors other than blue. In the past, jeans were considered masculine and unisex, but they viewed jeans as an apparel that was comfortable to wear and made it easier to move. Female students had a higher tendency to be fashionable than male students, and their preference for jeans was consequently different. Jeans manufacturers should take those characteristics into account to produce products in different colors and form.

Conventional upper extremity rehabilitation paradigm after brain injury has several shortcomings that is monotonous, simple, and repetitive in exercises over a long period of time, thereby causing training efficiency to decline as a consequence of low interest and participation. To resolve this issue, this paper proposes a new rehabilitative program integrating a wearable device integrated with EMG and motion sensor and a mobile game for the upper limbs' rehabilitative training. The developed wearable device is manufactured in the form of band, making it easy to wear. The mobile game is designed to enable rehabilitative training through games reflective of flexion, extension, abduction, and adduction identified by motion sensors along with grasp motion recognized by EMG signals measured from the wearable device. It also provides a tailored rehabilitative environment suitable for individual patients based on difficulty adjustments. As a consequence of applying the developed program to 14 brain injury in need of the upper limb rehabilitation and taking surveys on the utility of the developed rehabilitative program, the responses indicated that the developed rehabilitative program is far much more interesting and fun than the conventional rehabilitative program, further to the desire of those surveyed to reuse the developed program in the future.
