We developed lead gloves that minimize radiation dose to the operator's hands during interventional radiological procedures and that do not impede the operator's surgical capabilities. Existing lead gloves can protect the operator's hands by shielding radiation, but use of such gloves may impair preception sensitivity, resulting in a reduction in the operator's surgical ability. Accordingly, in this study, we developed modified lead gloves that can reduce radiation dose while maintaining operator sensitivity during procedures by modifying the operator's main surgical finger area in existing lead gloves. To evaluate the performance of developed modified lead gloves, radiation was applied in surgical conditions without gloves and with surgical gloves, lead gloves, and modified lead gloves. The radiation dose was evaluated for each condition. When the modified lead gloves were worn, the degree of shielding was similar to when conventional lead gloves were worn. Based on these results, if the operator wears modified lead gloves during interventional radiological procedures, they will protect the hands from radiation while maintaining physical sensitivity in the hands.

손가락 골절 치료 후에는 장시간 사용하지 않아 손가락 힘줄 운동 능력이 떨어져 관절이 뻣뻣해지고, 경직된다. 이것은 근력손실 및 유연성 저하를 비롯한 손 사용의 어려움으로 이어질 수 있다. 이를 해결하기 위해서는 손가락의 유연성 회복과 근력 강화를 위한 반복적인 재활 훈련을 해야 한다. 본 연구에서는 집에서도 사용할 수 있는 손가락 힘 훈련용 웨어러블 장갑 시스템을 제안한다. 제안하는 시스템은 FSR센서를 사용하여 힘을 측정하며, 신호 획득을 위한 맞춤형 PCB를 적용했고 고무 밴드를 사용하여 크기를 조정할 수 있다. 균형잡힌 손가락 근력 훈련 평가를 위해 네 가지 경우의 동작에서 쥐는 힘 측정 결과를 분석하였다. 본 연구에서는 다섯 손가락 힘의 중심을 나타내는 벡터를 제안하며, 힘의 균형 수준을 수치적으로 나타낼 수 있음을 보였다.

The rapid increase of electric power demand and the strong requirements for interuptiom-free made most distribution works being done by interruptiom-free work techniques. These trends lead to increase of accident by electric shock. It goes to prove that more than 80% of electric accident is due to the hot line works. Therefore, the countermeasures are very urgent. This paper suggests the improvement to prevent the work accident by interruption-free work through the examination of the present situation of interruption-free work techniques as well as analysing the problems in terms of live-line works and working procedures. These improvement will contribute to reduce the work accident in live-line work and enhance the construction quality by training and managing workers effectively.
