Mobile (smartphone) search engine marketing is increasingly important. Accordingly, the development of visual apparel search technology to obtain easier and faster access to visual information in the apparel field is urgently needed. This study helps establish a proper classifying system for an apparel search after an analysis of search techniques for apparel search applications and existing domestic and overseas apparel sites. An annotation technique is developed in accordance with visual attributes and apparel categories based on collected data obtained by web crawling and apparel images collecting. The categorical composition of apparel is divided into wearing, image and style. The web evaluation site traces the correlations of the apparel category and apparel factors as dependent upon visual attributes. An appraisal team of 10 individuals evaluated 2860 pieces of merchandise images. Data analysis consisted of correlations between apparel, sleeve length and apparel category (based on an average analysis), and correlation between fastener and apparel category (based on an average analysis). The study results can be considered as an epoch-making mobile apparel search system that can contribute to enhancing consumer convenience since it enables an effective search of type, price, distributor, and apparel image by a mobile photographing of the wearing state.

The purpose of this study is to grasp the actual wearing conditions, inconvenience and problems with cycle wear. To attain this purpose, a questionnaire was completed by direct observation and by interviewing bicyclists. The questionnaire was given to 273 bicyclists. The questionnaire consisted of items that are related to concerns with dressing appropriately and enhancement of physical performance through dress. Following are the results of this study. According to the survey, many of them purchased imported cycle wear rather than national cycle wear, and the satisfaction according with purchase rate was low. Bicyclists were uneasy with finding right size cycle wear especially for women. It turned out that the area of the knee and elbow are mostly the areas that they get hurt while riding. Even though the knee and elbow are the mostly hurt area, bicyclists do not prefer to wear appropriate protector for the knee and elbow to excel in their performance in cycling. In material related questions, lower dissatisfaction was indicated for the lints caused by fraction. Average satisfaction was indicated for the distortion after washing, changes in color, touch of the fabric, matters with static and sweat. With regard to the areas where the bicyclists felt discomfort was highly indicated with lower-body clothing. Discomfort was highly indicated with crotch area when riding long period of time. Also when riding a cycle, discomfort was indicated with the leggings cuffs when it comes upward with riding motion. Most of the bicyclists felt the tight fitting leggings were embarrassing.

This study examined the current state of snowboarding apparel. We investigated the preferred design, the required functions, and inconvenient factors in snowboard apparel through interviews with snowboard pro-players and questionnaires with functional apparel consumers. The research was conducted as follows. In order to raise problems through interviews with pro-snowboarders and grasp the individual traits of consumers, a survey was conducted with male and female consumers in their 20s-30s who enjoy snowboarding and those who had purchased specialized brand snowboarding apparel more than once. After the survey with consumers, this study set the classification standard for snowboard maniacs according to snowboarding frequency and classified the snowboarders into two groups. Both groups carry MP3 players most frequently in ordinary times and they preferred notable and brilliant colors and partially-used patterns (printed patterns). Through the investigation of the mobile functions that the snowboarders wanted for snowboarding apparel, it was found that the most preferred functions were those of listening to music and photo/video image-taking.

This study intends to provide sources which enable students to satisfy uniform design as I surveyed preferable uniform design and degree of satisfaction of uniform design to students. The subjects were gathered into 91 middle-high schools and surveys were done among 400 school girls. The results are as follows; 1)The survey of uniform which students wear. For jacket, tailored collar which is single breasted is most common and for blouse, puff sleeve, soutein collar, shirt collar is common. For skirt, lastly, they usually wear side pleats skirt. 2) Thoughts of uniform students preferred uniform to casual. The merit of wearing uniform can represent themselves as the ‘students’on the other hand, the demerit is shown that uniform is inconvenient enough to move. 3)Preference of uniform design. Students prefer tailored jacket, shirt blouse, flare skirt. Basing on these results above, I’d like to suggest something about uniform. The demerit of wearing uniform lies in inconvenience. It would weaken the degree of satisfaction of uniform and have a negative influence on students in physical and mental side. So we have to find out the concrete problems, at the same time, develop measurable study which fit for body. Adolescence is period of developing and establishing self. So they really need rather creative educational atmosphere than stereo typed-control. Reflecting this opinion, Clothing habits can play an important role and in future it is desirable to have students wear not uniform but casual.

Firefighters wear Personal Protective Equipment (PPE) for protection from environmental hazards. However, due to the layers of protective functions, the PPE inevitably adds excessive weight, bulkiness, and thermal stress to firefighters. This study investigated the adverse impact of wearing PPE as an occupational stressor on the firefighter's cognitive functioning. Twenty-three firefighters who had been involved in firefighting at least for 1 year were recruited. The overall changing trend in the firefighter's cognitive functioning (short-term memory, long-term memory, and inductive reasoning) was measured by the scores of three standardized cognitive tests at the baseline and the follow-up, after participating in a moderate-intensity physical activity, wearing a full ensemble of the PPE. The study findings evinced the negative impact of the PPE on the firefighter's cognitive functioning, especially in short-term memory and inductive reasoning. No significant influence was found on the firefighter's long-term memory. The results were consistent when the participant's age and BMI were controlled. The outcomes of the present study will not only fill the gap in the literature, but also provide critical justification to stakeholders, including governments, policymakers, academic communities, and industry, for such efforts to improve human factors of the firefighter's PPE by realizing the negative consequences of the added layers and protective functions on their occupational safety. Study limitations and future directions were also discussed.

Recently the use of personal mobility devices is rapidly increasing, and the businesses related to personal mobility devices are quickly growing as well. Although the use of personal mobility devices provides convenience for short distance movements, many problems occur due to the lack of safety devices and the absence of associated road traffic laws. The number of accidents caused by using personal mobility devices continues increasing every year, and the injuries or deaths are seriously happening with those accidents. When using personal mobility devices, there are basic safety precautions such as wearing a helmet, prohibiting boarding with more than two people, prohibiting boarding with more than 100kg, prohibiting using after drinking alcohol, and so on. However, it is exposed to traffic accidents because there is no way to check before using the system. Therefore, to ensure the user's safety in using the electric kickboard among personal mobility devices, this paper proposes a system that can check the user's safety state before using the electric kickboard. It is possible to safely use personal mobility devices and prevent accidents by proposing a system structure of the electric kickboard that can be used after checking for the use of more than two people, overweight, wearing a helmet, and drinking alcohol.

In this study, we explored the possibility of using sympathetic skin response (SSR), a type of electrodermal activity (EDA), as a method of evaluating a subject's responsiveness to physical or psychological stimulation. To provide physical and psychological stimulation, walking on an acupressure plate and a roller coaster virtual reality experience wearing an HMD (head mounted display) were used. Walking on an acupressure plate significantly increased the SSR signal compared to walking on the bare floor. Additionally, it was observed that the SSR response significantly increased while the subject was wearing an HMD and experiencing a roller coaster compared to the resting state of sitting on a chair. The SSR response to physical or psychological stimulation increased in all subjects, but the degree of reactivity differed. These experimental results suggested that sympathetic skin response (SSR) is a useful tool as a biosignal that can be used to evaluate the human body's responsiveness to physical stimulation or psychological stimulation using virtual reality.

The ethnic dress of Germany's Black Forest, called Tracht, dates back to the 16th century. Although most people living within the Black Forest do not presently wear Trachten, some persistence in this tradition exists. This study explored the factors that have supported the persistence of the Trachten tradition, specifically related to the wearing and crafting of Trachten by women, in a contemporary society. A qualitative, ethnographic approach was adopted. Data were collected via observations and interviews in the Black Forest. Thematic analyses revealed that the maintenance of the Trachten tradition was linked to varied factors that revolved around the overarching themes of both persistence and change. Interpretations were supported by theory proposing that ethnic dress is not static, but rather, changes across space and time in ways that enable its persistence. The persistence of the Trachten tradition was linked to formalized practice, meaningful identities, and desires to preserve and promote local culture. Additionally, the persistence of the Trachten tradition was fostered by change in the tradition, including the conceptualization of Trachten as a "lived practice" and the negotiation of Trachten authenticity.

The effects of heat treatment temperature (HTT) of polyacrylonitrile-based carbon fiber (CF) on the mechanical, thermal, and tribological properties of C/C composites were investigated. It was found that HTT (graphitization) of CF affects the thermal conductivity and mechanical and tribological characteristics of C/C composites. Thermal treatment of fibers at temperatures up to $2800^{\circ}C$ led to a decrease of the wear rate and the friction coefficient of C/C composite-based discs from 7.0 to 1.1 ${\mu}m$/stop and from 0.356 to 0.269, respectively. The friction surface morphology and friction mechanism strongly depended on the mechanical properties of the CFs. The relief of the friction surface of composites based on CFs with final graphitization was also modified, compared to that of composites based on initial fibers. This phenomenon could be explained by modification of the abrasive wear resistance of reinforcement fibers and consequently modification of the friction and wearing properties of composites. Correlation of the graphitization temperature with the increased flexural and compressive strength, apparent density, and thermal conductivity of the composites was also demonstrated.

This study was performed to investigate the effect of kangaroo care on anxiety and confidence and gratification of mothering role in mothers of low birth weight infants. The subjects were 30 mothers of low birth weight infants, sixteen for the kangaroo care group and fourteen for the control group, whose infants hospitalized in two neonatal intensive care unit at two university-affiliated hospital. The kangaroo care was applied 9 times during the twenty six days with 40 minutes for each session. The kangaroo care provides the skin-to-skin contact during which a low birth weight infant wearing a diaper and a hat is placed on its mother's chest. The questionnaire, state anxiety was completed before beginning the first intervention. The questionnaire, state anxiety and confidence and gratification of mothering role were completed at 2 weeks after discharge. The data were analyzed by a SPSS program. The results were as follows : 1. There were no significant differences in the state anxiety between the kangaroo care and the control group before beginning the first intervention. The state anxiety was significantly lower in kangaroo care group than in control group. 2. The confidence of mothering role was significantly higher in kangaroo care group than in control group at 2 weeks after discharge. 3. The gratification of mothering role was significantly higher in kangaroo care group than in control group at 2 weeks after discharge. 4. In mothers of low birth weight infants, the state anxiety was negatively correlated to the confidence of mothering role and the gratification of mothering role at 2 weeks after discharge. And the confidence of mothering role in mothers of low birth weight infants was positively correlated to the gratification of mothering role at 2 weeks after discharge. These results suggest that kangaroo care is an effective nursing intervention for mothers of low birth weight infants in reducing the state anxiety, improving the confidence and gratification of mothering role.
