In recent years, there has been an increasing interest in tangible sports simulators with the success of golf simulator. The main purpose of this study is to develop a tangible snowboard simulator for the beginner using virtual reality technology. This paper proposes an interactive virtual coach and high fidelity virtual environment for snowboard training. The virtual coach offers an intuitive guidance and personalized coaching feedback about the 5 fundamental riding skills. The virtual training environment uses the stereoscopic display system and motion platform to create more realistic training situation. We expect virtual reality will be used as a training aids in many sports such as taekwondo, baseball, archery and so on.

The people who is returning to the community after hospital treatment are faced with the choosing where to proceed with rehabilitation exercise with an appropriate exercise specialists based on the current health condition of them. It is required to supprot a personalized exercise rehabilitation service (hereinafter referred to as ARES system) in the community based on individual disease information and health conditions based on hospital clinical data. In this study, we designed a resource management system for online-to-offline (O2O) based coach matching to improve accessibility with facilities and coaches for exercise rehabilitation in the community.

The concentration of dye uptake and the fastness improved when cotton and silk fabrics were treated with chitosan, a natural polymer. In this study, the effect of chitosan treatment was reviewed after the printing of cotton and silk fabrics padded with chitosan. When the change of physical and mechanical properties of printed fabrics was reviewed (as the concentration of chitosan increased) the thickness and weight increased a little, and the air permeability increased significantly than those untreated with chitosan. The dye uptake increased, accompanying a darker color shade, and the wash fastness increased 1/2-1 grade. The analysis results of enlarged images of printed patterns indicated that the width and area deformations were minimal as the concentration of chitosan increased when compared to untreated fabrics. Therefore, the dyeability and pattern quality were excellent after printing the chitosan-treated cotton and silk fabrics with cochineal dyestuff.

Cochineal dyeing was applied to natural fiber fabrics, cotton and silk fabrics, and synthetic fiber fabrics, nylon and polyester fabrics. Chitosan-pretreatment was applied to the fabrics in order to investigate the effect of chitosan treatment on the dyeing behavior. The effect of chitosan treatment on the mordanting was also investigated by incorporating Cu-mordant on the chitosan-treated or chitosan-untreated fabrics during the dyeing process.

Chitosan pre-treatment of the fabrics prior to the dyeing processes has been reported to increase the uptake of natural dyestuffs. In this study, cotton, nylon, and PET fabric specimens were pre-treated with chitosan prior to the dyeing (Method 1), or the state of chitosan acid salt formation, coated on the yarn surface, was destroyed prior to the dyeing process by alkaline neutralization process (Method 2). In case of the acid salt formed cotton (Method 1), treated fabrics showed more yellowish color component of cochineal, while alkali-treated (Method 2) cotton showed more uptake of bluish color of cochineal.

본 프로젝트는 운동 초보자들을 대상으로 운동방법, 동영상, 다이어트 식단 짜기, 칼로리 계산, 메모장, 스톱워치 등 운동 초보자들에게 유용한 정보들을 쉽고 간편하게 전달할 수 있는 운동 코치 App이다. 일반적으로 운동을 시작할 경우 계획과 정보가 없이 시작하고 자신이 알고 있는 국한된 운동만 하기 때문에 효율성과 흥미가 떨어져 금방 지치게 되어 쉽게 포기하는 경우가 많다. 이러한 체계적이지 못하고 비효율적인 운동 방식을 간편하고 편리하게 활용할 수 있는 운동관리 앱을 개발하였다.

It has been reported that natural dyeing is impossible without pre-treatment with metal mordanting agents. However, pre-treatment with chitosan, which has high affinity to natural dyes, could result in an excellent dyeing with various natural dyes. In this study, three treatment methods were employed; 1) Using PET without any pre-treatment (Method 1) 2) Using PET with chitosan acid solution pre-treatment (Method 2) 3) Using PET with chitosan pre-treatment and subsequent crosslinking using citric acid (Method 3) Method 2 and 3 enhanced the Cochineal dyeability remarkably compared to Mehod 1. Washfastness was also enhanced, and moisture content, static property, abrasion resistance, and fabric hand changes were investigated.
