A fundamental function of court sport shoes has been considered as the protection of human feet from unexpected injuries. But, recently its role for improving the playing competency is being regarded as a more important function. In connection with this situation, intensive efforts are being world-widely forced on the development of court sport shoes proving the excellent playing competency, by taking kinesiology and biomechanics into consideration. However, the success of this goal depends definitely on the shoes design based upon the reliable evaluation of shoes functional parts. This paper addresses the application of finite element method to the evaluation of landing impact force of court sport shoes. In order to reflect the coupling effect between leg and shoes accurately and effectively, we construct a fully coupled shoes-leg FEM model which does not rely on the independent experimental data any more. Through the numerical experiments, we assess the reliability of the coupled FEM model by comparing with the experimental results and investigate the landing impact characteristics of court sport shoes.

The purpose of this study was to review of animal-assisted therapy. Method: Animal-assisted therapies (AATs) in domestic and international studies (68 cases) were analyzed by searching databases, KERIS & KISS, and the Pub MED(NCBI). Result: In AATs, a few animals were used for the various disease or disorder. Dog centered therapies were most common.. AATs were used in the various disorder and disease. For the psychological effect, majority of the outcome variables were depression and anxiety. For the physical effect, the most outcome variables were blood pressure, heart rate, and stress hormone. However, These results show that AATs were confined to specific areas such as sensation-centered therapies. Conclusion: AATs had positive effects both in physical and psychological factors even if the study areas have not been applied to the various condition. The further research is needed to identify scientific grounds for the effects of the interventions through various therapies.

Recently, with the popularization of smartphones, augmented reality has become even more familiar to the public as an application that can provide realistic images as a tool for location-based services. Therefore, as a location-based application for smartphones that is appropriate for the application of augmented reality technology, the study develops a golf information system. Golf is the sport for which we should exactly know the accurate shape or distance to the destinations or obstacles, so the sport is suitable for applying the augmented reality technology. Even though the sport of golf has constantly increasing population to play it with the popularization of it, presently released golf-related smartphone apps are established as 2D images or in GPS basis; thus, they lack a sense of realism unfortunately. Thereupon, this study develops a golf information system by modifying and complementing usefully Mixare, the open source for augmented reality, for the sport of golf into an augmented reality-based system that can provide various information according to the actual environment of the golf course and describes how to apply it actually to the golf course.

Recently, intensive research efforts are world-widely forced on the development of sport shoes improving both the injury protection and the playing performance by taking kinesiology and biomechanics into consideration. However, the success of this goal depends definitely on the reliable evaluation of the dynamic responses of sport shoes and human foot, particularly the landing impact characteristics. It is because the landing impact force is a main source of unexpected injuries and influences the playing performance in court sport activities. This paper addresses the application of finite element method to the evaluation of landing impact characteristics of barefoot and several representative court sport shoes in running. In order to accurately reflect the coupling effect between human foot and shoes accurately, we construct a fully coupled three-diemensional foot-shoe FEM model which does not rely on the independent experimental data any more. Through the numerical simulation, we assessed the reliability of the numerical FEM model by comparing with the experimental results and investigated the landing impact characteristics, such as GRF, MIF, acceleration and frequency responses, of representative court sport shoes.

In september 2004, a new pilot certificate scheme referred to as Sport Pilot Certificate was declared official and standardized in the US. The designation of Light-sport aircraft and the details of the relevant pilot certificate policy was announced out of the perception that a new regulation is required to be applied whereby the limitations on the manufacturing process enhancements and current aviation rules are considered the triggering factors. US Federal Aviation Regulation retains a comprehensive range of airworthiness certificates and aircrafts are managed systematically in accordance with FAR 21, 103. The airworthiness are further segregated into sub categories, which allows differentiated management. Korean Aviation Law classify aircraft into five different categories and powered air vehicle that weighs more than 150kg(19liters fuel capacity) for one seat, 225kg for two seats(38liters fuel capacity) while the systems that fall under a specific mass threshold level are known as ultralight vehicle. The research discusses the policy of the sport pilot certificate and the light-sport aircraft ratings announced official by the Federal Aviation Administration in an intuitive fashion with the analysis of the operations providing the evidence as to the viability of adopting the policy in local grounds. Based on the findings, the report discusses the case for introducing the light-sport aircraft and make recommendation on a strategy of applying the policy in Korea with respect to the pilot certificates, safety agenda, and the written test for the pilot certificate, and operating efficiency.
