In order to improve the lithium ion battery's performance, the carbon nanofibers were introduced to the anode electrode fabricated with natural graphite particles. The influence of structural adjustment of the particles by the introduction method of carbon nanofibers and the content of carbon nanofibers on the electrical property and charge/discharge characteristics of the electrode were investigated. The electrode fabricated with the mixture of 10 wt% of carbon nanofibers grown separately and 90 wt% of graphite particles showed an excellent discharge capacity of 400 mAh/g and the improved cycle performance. The improved performance could be explained by that the carbon nanofibers shortened and uniformly distributed on the surface of graphite particles by ball milling increased the stability for the intercalation/deintercalation of lithium ion and increased the electrical conductivity due to the closed packing between graphite particles.

텃밭을 중심으로 한 원예치료 활동이 대상자를 치료하는 영역을 넘어서 직업재활의 가능성을 보여준 연구라 할 수 있다. 결과에서와 같이 각각의 대상자들이 직업적응력 향상을 가져왔다는 것에서 만족하기 보다는 대상자에게 적절한 직업재활의 영역까지 연계할 수 있도록 지속적인 연구와 노력이 있기를 제언한다.
