해마다 늘어나는 장애 인구에 비례하여 재활치료 수요도 늘고 있다. 이는 국민 개개인이 부담해야 할 사회적 비용이 그만큼 높아짐을 의미한다. 이 비용을 줄일 수 있는 몇 가지 대안 가운데 하나가 기능성 게임이다. 본 논문에서는 기본적인 활동이 가능한 70만 명 이상의 재활치료 수요자에 적용할 수 있는 기능성 게임을 설계하였다. 특히 깊이정보를 활용하는 기능성게임 구조 설계를 제안하였는데, 이는 능동적 재활치료를 가능하게 함으로써 수동적인 것에 비해 좋은 효과를 기대할 수 있다. 또한 최소의 인력으로 운영할 수 있는 시스템을 기대할 수 있다. 설계 검증 단계에서는 게임 진행의 주요 기능 가운데 일부를 실제로 개발하여 시험함으로써 연구의 타당성을 높였다. As the number of disabled people increases each year, the number of rehabilitation programs available is also in great demand. This means the cost of social welfare subsequently skyrockets each year as well. One of the plans to reduce this skyrocketing social welfare cost is to provide serious game programs to the over 700,000 people who are in rehabilitation programs every year. The main goal of these programs is to have them exercise on their own with the aid of the game program, which accelerates their rehabilitation more effectively than through the use of passive rehabilitation treatments by others. The serious game program requires very minimal manpower. During the verification of our serious game programs, we have developed some of the designed programs and have tested out successfully.
EMI Shielding Properties of Carbon Nanofiber Filled Poly Vinylidene Fluoride Coating Materials

The effectiveness of electromagnetic interference (EMI) shielding was measured for poly vinylidene fluoride (PVDF) coating materials containing carbon nanofibers. When the thickness of carbon nanofibers filled PVDF coating materials varied from 25 to 100㎛, the electrical conductivity of coating materials was almost constant around 2.0 S/㎝ except for the case of 25㎛. Although the electrical conductivity should not change with the thickness of coating, the lower value with the thinner thickness could be related to the lack of uniformity at the lower thickness range. The specific surface area and electrical conductivity of filler were important factors for the shielding effectiveness (SE) of the coating materials. In order to apply carbon nanofibers as EMI shielding materials, large specific surface area and high electrical conductivity were desirable. The SE of the coating material showed a high value with the mild heat treatment at 1100℃ for 1 h and was proportional to the electrical conductivity of the coating materials.
