본 논문에서는 자전거 피팅을 좀 더 정교하고 신속하게 진행하기 위해 자전거 피팅 소프트웨어와 하드웨어를 통합한 시스템을 개발하기 위한 DB구축을 목표로 포괄적인 자전거 피팅 방법의 표준화가 요구됨에 따라 다수의 임상결과와 실험을 통해 이에 맞는 자전거 피팅 방법을 제안한다. 이 자전거 피팅 방법은 심층상담, 자전거체크, 정교한 신체사이징 및 분석을 통해 라이더를 위한 자전거 세팅 값을 결정할 수 있으며 이 세팅 값으로 조정된 자전거에서 고정 라이딩을 통해 자세와 페달링 토크를 분석하고 이을 통해 가장 효율이 높은 세팅 값을 찾아 자전거를 라이더의 요구에 맞게 최적화 할 수 있는 피팅 방법에 대한 결과를 도출 했다. 이와 같은 피팅 방법은 자전거 라이더의 만족도를 높일 수 있으며 정확한 자전거 세팅 값을 통해 부상예방도 기대할 수 있다. 본 논문은 자전거피팅 방법에 대해 국내·외를 통틀어 가장 구체적으로 제시된 결과로 본 논문이 최종 추구하는 자전거피팅 시스템이 구현된다면 글로벌 시장에서도 인정받을 수 있는 자전거 피팅 기술로 자리 잡을 수 있다.

This paper proposes a corresponding bicycle fitting method through a number of clinical results and experiments, with the aim of standardizing the comprehensive bicycle fitting method with the aim of developing a system that incorporates bicycle fitting software and hardware to proceed more precisely and quickly. This bicycle fitting method can determine the value of bicycle setting for the rider through in-depth counseling, bicycle check, sophisticated body sizing and analysis, and from the bicycle adjusted to this setting, the posture and pedaling torque can be analyzed through fixed lading, which can be followed to find the most efficient setting value and optimize the bicycle to meet the needs of the rider. Such a fitting method can increase the satisfaction of bicycle riders and also be expected to prevent injury through accurate bicycle setting values. This paper can be established as a bicycle fitting technology that can be recognized even in the global market if the final bicycle fitting system is implemented as the result presented in the most concrete domestic and foreign countries.

The purpose of this study was to investigate the relationship between recreation specialization of bicycle riders and purchase decision factors for bicycle products. A total of 351 respondents were selected using the stratified sampling method. From the statistical analyses, two meaningful results were extracted. First, there were significant difference in specialization sub-factors and purchase decision factors on the base of demographical characteristics. Specially, riding club participants were most different from non-participants in all factors. Second, some specialization sub-factors influenced some purchase decision factors positively, or negatively. In special, emotional specialization had positive effects most significantly on many factors of purchase decision. Cognitive specialization, however, had no any effect on purchase decision factors. Moreover, behavioral specialization had negative effects on some purchase decision factors.

본 프로젝트는 날씨와 GPS 위치정보를 이용해 사용자들에게 자전거 라이딩을 하기 전에 현재 및 예상날씨정보, 로드맵을 제공하는 자전거 애플리케이션이다. GPS 위치정보를 활용한 네비게이션 기능으로 사용자가 자전거 라이딩을 할 때 현재위치, 목적지 경로, 주행 시간, 주행 경로와 같은 유용한 정보들을 제공해주는 프로젝트이다. 일반 자전거 어플리케이션은 자전거 속력, 현재 날씨 등과 같이 간단한 정보들을 제공해 주는 것에 반해 본 프로젝트는 자전거 라이딩 사용자들에게 날씨뿐만 아니라 로드맵을 제공하여 본인의 위치, 경로, 등을 제공하며 길 찾기, 자전거 라이딩 정보를 제공함으로써 사용자들이 자전거를 좀 더 효율적으로 탈 수 있게끔 자전거 어플리케이션을 개발하였다.

This study is to measure traveling experience of bike riders whom going long distance trip. Bike paths and bike riding are crucial element for modern people's life style. At the same time, a bicycle trail is being developed by the National Bicycled-Oriented Chair Plan, which was established in 2009 by the National Bike Policy Master Plan. 13 million bike riders in Korea is keep on trying the long distance bike trip and its number is increasing every year. Accordingly, the Ministry of Public Administration and Security decides to promote the convenience of riders by developing bicycle app for long distance rider. The study attempted to assess usability of this app with 39 bike applications whom currently using the bike application. Afterwards, the researchers tests 11 hypotheses through in-depth interviews of six activated members. In sum, Bicycle travelers should be provided with bike trail guidance based on theme section skill, provided in-time speed distance related information, communicated with other bike riders, given tips for bike supplies and maintenance, and provided English language service. The study hopes to help find a customized service for bike travelers.

With the growing number of people using bicycle, the number of bicycle accidents also has been increasing. It is said that bicycle accident can be reduced up to 11%~44% when riding a bicycle if LED light is used. The headlight of the bicycle makes exposure effect to the opposite side of bike rider while taillight makes exposure effect to the rear bike rider for improving safety. Bicycle safety device capable of displaying a change of direction by LED is implemented in this study in response to control button signal. This signal makes LED light which is installed in pedal and wheel of bicycle as a module type emitting or flickering during the fixed hour. Bicycle auxiliary device in pedal which is able to improve safety using LED when bikers are riding a bike at night is developed in this study. Bicycle safety device applying wireless communication technology will be expected alternative technology in the future to solve a social problem such as energy, environment, and safety.

Bicycle riders complain of many inconveniences when wearing glasses, sunglasses and masks. The disposable fine dust mask has been developed to resolve such inconveniences of bicycle riders. The scope of research is limited to the fiber which generates one-time static electricity and the shape of the mask due to the characteristic of fine dust mask. The purpose is to design and make the fine dust mask with a simple production process. The new disposable fine dust mask has secured enough space of the mask in front of the mouth by longitudinal folding and minimized stuffiness by maintaining the shape of the folded part to prevent touching the mouth even by heavy breathing. The streamlined sponge is attached at the part of nose support and the area of the cheek has been expanded to be about 2.5cm wider than ordinary masks to improve tight seal at the side. In addition, a new disposable fine dust scarf mask has been developed to block ultraviolet rays for the face and neck while filtering fine dust with the tight fine dust mask.
