The incidence of in-line skating injuries has increased with the rapid growth in the sport's popularity. The purpose of this article is to describing the type of the inline skating and document basic skills, protective equipment use, identify contributing or precipitating factors associated with injuries. Loss of control and inexperience were factors contributing to the injuries. Also protective equipment among skaters was underused. In conclusion, the safety education program for inline skating, optimal design and efficacy of protective equipment should identify with further study.

컴퓨터를 이용한 멀티미디어의 발전으로 인하여 3차원 가상현실의 구현이 빠르게 발전되어 가고 있다. 특히 멀티미디어 컨텐츠에서의 게임은 가장 인기 있고 넓은 시장을 가지고 있다. 하지만 대부분은 제한된 인터페이스의 데스크탐용 PC에 한정되어 있다. 직접 체험을 하며 게임을 하는 체감형 시스템을 갖춘 게임의 개발은 아직 활성화되지 않고 있다. 최근 인라인 스케이트가 여가를 즐기는 레포츠로 전세계적으로 인기를 얻고 있다. 그러나 인라인 스케이트를 충분히 즐기기 위해서는 넓은 공간이 제공되어야 하지만 넓은 공간은 제한되어 있으며, 일반도로에서 주행을 할 경우 대형사고에 노출되는 문제점을 가지고 있다. 본 논문에서는 이러한 인라인 스케이트의 위험에 노출되는 문제점을 해결하기 위하여 한정된 공간에 인라인 스케이트를 즐길 수 있는 전동장치인 스케이트 밀을 개발하고 사용자의 위치를 측정하여 체감 게임을 구현하고자 한다.

Objective: Recently, inline skates are populary increasing and have become major recreational activities. This study was performed to determine the effective prevention means on various extremity injury by investigating injury severity occording to acute injury and overuse injury. Results: Acute inline skating injury was experienced mostly among the age between 6$\~$14 years old children after school around nearby their home without using no appropriate safety device gear. The wrist injury was mostly happened. We think that overuse injury is related to boot itself, boot fitting and improper skating techniques. Conclusion: So afterall, appropriate safety equipment wearing in inline skating at the safe place after learning about the skating skills can reduce the acute inline skating extremity injuries. Choosing a pair of good fitting boots, performing the exact pushing techniques and take good rests in the middle of skating frequently can reduce the overuse injury.

Injection molding is the most commonly used process that uses plastic material. Today, the uses of plastic material are continuously increasing, and the range of application is also being extended by the development of novel materials. An inline skate consists of 4 components: the boot, frame, wheel and brake. Among these components, the frame is the most critical. The injection formability for a variety of injection materials for inline skate frames was studied. We also studied the injection formability of the product for various sizes of the runner and gate. In this study, injection molding analysis was performed using MOLDFLOW, and structural analysis was performed using ANSYS.

Injection molding process is one of the most important methods to produce plastic parts with high efficiency and low cost. Today, injection molded parts have been increased dramatically the demand for high strength and quality applications. In this study, In-line skates are made of Al alloy and plastic materials to replace the frame for the optimization process is all about. I interpreted through mold design, Injection molding process that minimizes the runner and the gate dimension will determine the size and shape. Runner and gate dimensions of change based on availability of the product, I'll discuss the injection molding. This report investigates that the optimum injection molding condition for minimum of shrinkage. The FEM Simulation CAE tool, Moldflow, is used for the analysis of injection molding process.
