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.

The purpose of this study is to provide essential information conducive to designing efficient cycling apparel for everyday wear. To this end, this study identified key situations that cyclists face while riding their bicycles as well as clothing functions that are necessary for each situation. Furthermore, this study also analyzed the current trends in cycling apparels and hybrid designs. In order to analyze the current trends of clothing functionality in domestic and foreign cycling apparel brands, the researchers of this study first reviewed existing literature on the functionality of cycling clothing. Then a focus group, which comprised of two experts in cycling fashion brands and fourteen consumers, was formed and in-depth interviews were conducted to identify the major conditions related to bicycle riding. Based on the results of the interview, the study, then, classified 700 images of cycling clothing from exhibitions and 1,541 images of cycling clothing that were launched by domestic and foreign fashion brands. The results of this study were as follows. First, there were three major conditions in bicycle riding: night riding, weather changes and riding convenience. Second, functionalities required for each riding condition were as follows: visibility for night riding, comfort, waterproofness and heat preservation properties for weather changes, and elasticity, protective properties and storage capacity for riding convenience. Finally, hybrid designs for each riding condition were different from general designs.

The purpose of this study is to investigate the effects of napping of knitted fabric on wear sensation and physiological responses. Experimental garments were four types of warm-ups made of either $100\%$ PET or $65/35\%$ P /C and either napped or unnapped respectively. Two healthy young female adults were chosen as subjects for the experiment. Experimental room conditions were as follows: Temp., $22\pm0.5^{\circ}C$ R.H., $54\pm3\%$ and Air Velocity, 0.25m/ sec or 2. 86m/sec. The subjects exercised on bicycle ergometer and rested alternatively for totally 45-min. The results are summarized as follows. 1) With napped Warm-up, chest, back, mean skin temp. and microclimates, i.e., temp., relative humidity and water vapor pressure inside the clothing, were higher than with unnapped warm-up. And there was no difference in pulse rate between napped and unnapped warm-ups. 2) Wear sensations of thermal, humidity, tactile and comfort were 'more hot' and 'more uncomfortable' in 0.25m/sec air velocity. but in 2.86m/sec condition the tactile sensation was 'better' and 'more comfortable' with napped warm-ups. According to Pearson's Correlation, among various kinds of wear sensations, tactile is most related with comfort. From these results, it can be concluded that napped fabric decreases the rate of heat trans? mission and moisture diffusion through the clothing. Therefore skin and body temp. and temp., R.H., Vapor Pressure inside the clothing are increased.

This study analyzed the consumer awareness of cycling wear using web mining, one of the big data analysis methods. For this, the texts of postings and comments related to cycling wear from 2006 to 2017 at Naver cafe, 'people who commute by bicycle' were collected and analyzed using R packages. A total of 15,321 documents were used for data analysis. The keywords of cycling wear were extracted using a Korean morphological analyzer (KoNLP) and converted to TDM (Term Document Matrix) and co-occurrence matrix to calculate the frequency of the keywords. The most frequent keyword in cycling wear was 'tights', including the opinion that they feel embarrassed because they are too tight. When they purchase cycling wear, they appeared to consider 'price', 'size', and 'brand'. Recently 'low price' and 'cost effectiveness' have become more frequent since 2016 than before, which indicates that consumers tend to prefer practical products. Moreover, the findings showed that it is necessary to improve not only the design and wearability, but also the material functionality, such as sweat-absorbance and quick drying, and the function of pad. These showed similar results to previous studies using a questionnaire. Therefore, it is expected to be used as an objective indicator that can be reflected in product development by real-time analysis of the opinions and requirements of consumers using web mining.

Bikers can be subjected to injuries from unexpected accidents even if they wear basic helmets. A properly designed airbag can efficiently protect the critical areas of the human body. This study introduces a wearable smart airbag system using machine learning techniques to protect human neck and shoulders. When a bicycle accident happens, a microprocessor analyzes the biker's motion data to recognize if it is a critical accident by comparing with accident classification models. These models are trained by a variety of possible accidents through machine learning techniques, like k-means and SVM methods. When the microprocessor decides it is a critical accident, it issues an actuation signal for the gas inflater to inflate the airbag. A protype of the wearable smart airbag with the machine learning techniques is developed and its performance is tested using a human dummy mounted on a moving cart.

Background: Adolescent risk behaviors are of concern because they are dangerous in themselves and have negative influences on adult health. Objectives: This study explored six health risk behaviors of a sample representing the adolescent population in Jeju. Methods: Frequency and percentage of risk behaviors were calculated. Additionally, the chi-square test was used to explore whether differences in experimentation with risk behaviors exist relative to gender and schooling levels. Results: There were six major findings in this study: (a) a lower rate of lifetime and current cigarette use among female students compared to male students, (b) a substantial portion of heavy drinkers, (c) a higher rate of lifetime drug use among female students than among male students, (d) a higher prevalence of suicide ideation among female students than among male students, (e) substantial percentages of students who did not usually wear seatbelts, motorcycle helmets, or bicycle helmets, and (f) a substantial portion of students who were not involved in vigorous physical activities. Conclusions: Since a substantial portion of adolescents have been involved with diverse risk behaviors, it is urgent to implement effective intervention strategies to reduce the rates of these behaviors.
