The purpose of this research was to understand the process of American women's adoption of knickerbockers from the mid-nineteenth to the early twentieth century. Articles and advertisements related to women's knickerbockers found from The New York Times were used as primary sources. Before 1920, women wore knickerbockers when they participated in sports including gymnasium, bicycling, and swimming. Knickerbockers were mostly worn with overskirts when women appeared in the public. Therefore, knickerbockers were categorized as underwear in the advertisements until the late 1910s. However, knickerbockers were even worn on the streets and in offices after American women gained suffrage in 1920. As more women adopted knickerbockers during the 1920s, the public criticisms and regulations on women's knickerbockers intensified. However, the articles on women's knickerbockers gradually disappeared from The New York Times, as they went out of fashion by the end of the 1920s. Considering the social situation and the change in womanhood during the period, I concluded that American women's adoption process of knickerbockers reflected the increase in women's mobility, and the change in gender roles and the definition of femininity.

The purpose of this study is to develop an aesthetic and functional bicycle wear for new senior women in their 50s and 60s. We developed bicycle wear that is friendly to bicycling posture and reflects the preference of new senior women. Both the expert group and the subject group evaluated the appearance, completeness of clothing and motion functionality. The results are as followed: First, in the evaluation result of the expert group regarding the appearance and completeness of clothing, high scores are given to design, materials, color scheme, the trends suitability as well as the appearance with regard to clothing fitness. Second, in the results of the evaluation of the appearance and movement functionality targeting the subject groups, movement functionality was rated higher than appearance. In the case of the appearance evaluation, adhesion of both jacket and pants was rated very highly, which is considered to come from the elasticity of the material. In the functionality evaluation, what were pointed out as inconvenient details in the prior studies were found to be all improved and the sleeves and armpit parts were rated highly. Therefore, the pattern design and the usage of the materials suggested in this study were found to be very suitable in the movement on the ride of bicycle.

The promotion of walking and bicycling is recently a hot topic in the urban planning and design field. Many planners have already examined the many components of the land use-transportation connection and built environment-physical activity link. A rapidly growing area of urban form research is to measure the level of walk-ability in urban environments. With this background, this research conducted a preliminary study to develop the evaluation indicators of pedestrian environments. Based on the literature reviews on walking or pedestrian environments, we proposed the seventeen indicators related with pedestrian facilities, road attributes and walking environment. We also performed a questionary survey to evaluate the satisfaction of their neighborhood pedestrian environments for 302 randomly selected adults living in the City of Changwon, Gyeongsangnam-do. Finally, this research provided the valid model to evaluate the effects of physical environmental factors on the walking satisfaction using factor analysis and multiple regression analysis.

Bikers can be subjected to accidents during their bicycling. Helmets are only good, if any, for their head protection. A wearable airbag can protect the human neck area if it is properly designed. This airbag system is composed of an inflater and an airbag. The inflater contains a pressurized gas cylinder and a piercing device. The airbag is an inflatable fabric surrounding the human neck. When a bicycle accident happens, a sensor captures the motion of the biker and a microcomputer sends a signal to open a valve in the inflator to supply the pressurized gas to the airbag. An important issue of this system is that the airbag should be quickly inflated to protect the human neck. This paper deals with the airbag inflation time simulation and some issues to design a wearable airbag system. Also, a prototype was tested to show its feasibility using a human dummy mounted on a running cart.

As the industry develops and quality of life increases, the concept of leisure is also changing. Bicycling is a healthy sport for exercising while enjoying nature, facilitating the enjoyment of a healthy life. As a result, the awareness surrounding bicycles has increased, and so has the interest in lighter and more luxurious carbon bikes. The number of domestic companies producing carbon bicycles frames is nil. In this study, we analyze the frames of existing foreign brands and analyze the deformation and stress concentration area according to the load of the frame, using the finite element analysis. In addition, we set up the range of stiffness based on the content of the structural analysis, to localize the carbon bicycle frame and famous foreign products, and compare the prototype with the stiffness by using bicycle molds for track races.

Objective: The purpose of this study was to investigate the effect of visual feedback bicycle training on running performance, maximal oxygen uptake and quadriceps muscle strength. Design: A randomized controlled trial. Methods: Fifteen healthy adult men with no musculoskeletal or nervous system disease and capable of bicycle training were included. After the pretest, subjects were randomly assigned to visual feedback bicycle training group and general fixed bicycle training group. Both groups were trained two times a week for three weeks, each week for a fixed time and number of repetitions, followed by a six week washout period and then crossing the training method. visual feedback bicycle training provides visual feedback of heart rate in real time using a monitor and a heart rate meter during bicycle training, and general fixed bicycle training performed general bicycle training without visual feedback. After training, each item was measured using a wearable technology, gas analyzer, isokinetic equipment. Results: The results of this study was significant differences in running performance, maximal oxygen uptake and quadriceps muscle strength in visual feedback bicycle training group (p<0.05). The differential effect was found between visual feedback bicycle training group and general fixed bicycle training group in running performance, maximal oxygen uptake, and quadriceps muscle strength (p<0.05). Conclusions: This study suggested that that visual feedback bicycle training can be applied as a useful training method to improve running performance, maximal oxygen uptake and quadriceps muscle strength.

Loss of postural stability can possibly lead to slip and fall accidents in the number of workplaces and everyday life. This study was aimed to examine the effects of whole body fatigue and partially limited visual field on the ability of maintaining postural balance during quiet standing. A group of twelve healthy male subjects participated in the experiment. Before and after experiencing the whole body fatigue induced by bicycling exercises, the position coordinates of subject's center of pressure (COP) were obtained under the two levels of visual field condition (i.e., open visual field and limited visual field). Four levels of the whole body fatigue examined were rest, 300watt, 600watt, and 900watt. Position coordinates of COPs measured on a force plate were then converted into the total length of postural sway path in both the medio-lateral (ML) direction and the anterior-posterior (AP) direction. Two-way ANOVA result showed that the length of sway path in the AP direction became significantly larger as the whole body fatigue accumulated. Post-hoc test revealed statistically significant differences between rest and 900watt and between 300watt and 900watt. The significant increase of the sway length was also found when the visual field was partially obstructed by the boxes. In the ML direction, however, there was no statistically significant difference of the postural sway in both the AP and ML directions. The results imply that the ability of maintaining postural stability can be reduced significantly due to such tasks along with whole body fatigue. The postural balance can also be impaired by the limited visual field.

The purpose of this study is to develop an aesthetic and functional bicycle wear for new senior women in their 50s and 60s. Based on the results of the survey, we developed bicycle wear that is friendly to bicycling posture and reflects the preference of new senior women. The results are as followed: First, emphasis is placed on the simple and functional design of the experimental wear consisting of jacket and pants. Jacket is different from the color scheme with the armhole princess line in order for the waistline to look slim. Pants are designed to hold the leg muscles tightly in order to help reduce the muscle fatigue on the bicycle ride. Second, cutting lines and coloring materials are used for the wearer to look slim and the safety of the wearer is planned to secure by inserting the reflective material along the cutting lines on the bicycle ride. Third, the pattern of the experimental wear is designed in consideration of the riding motion of the bicycle. Jacket is designed to have back length longer than front length as compared to the bicycle wears available on the market. Sewing lines in the armpit are designed to be eliminated in order to move the arms smoothly on the ride. Pants are designed to minimize the seam line in consideration of the movement of muscles and ligaments and the experimental wear is produced by combining the material with the functions of cool comfort and stretch.
