This paper describes a wall distortion calculation algorithm based on a single distance sensor module for walking assistance in an electric wheelchair. The proposed algorithm calculates the deviation from the wall using a single multi-domain ToF laser sensor. Calculate the angle of both end points of the measurement area from the center of the distance sensor and estimate the deviation by comparing it with the angle when it is parallel to the wall. To verify the performance of the developed technique, as a result of applying this technique to the wall at 0°, clockwise and counterclockwise 5°, 10°, 15°, and 20°, respectively, the result of the experiment was a minimum of 0.092° and a maximum of 0.628. It was confirmed that it has a high accuracy.

In this paper, we propose a system that has the function of notifying the structural characters in the fall of the elderly, To determine the fall situation, an external fall detection device is used. The system performs appropriate functions according to each situation through the information received from the outside. Through the experiment, it was confirmed that the characters including the contents of the accident situation and the accident situation were immediately sent to the guardian during the fall situation. Also, we confirmed that when a person leaves the safety zone, he / she sends a character including the location of the elderly person to the guardian.

N/A Background: Thoracotomy is the operation that produces the most postoperative pain, necessitating the highest requirements for postoperative analgesics. The common methods of treating postthoracotomy pain are the use of thoracic epidural analgesia, intemittent or continuous intercostal nerve blocks, intravenous narcotics and cryoanalgesia. We designed to assess the analgesic effect of epidural analgesia, cryoanalgesia and the combined analgesia in thoracic surgery. Methods: A prospective study was carried out in 59 patients undergoing elective thoracotomy for parenchymal disease. Patients were randomized into three groups: C (cryoanalgesia), CE (cryoanalgesia and thoracic epidural analgesia), E (epidural analgesia). All patients had standard anesthesia with endotracheal intubation using a double lumen endotracheal tube, and one-lung ventilation. Subjective pain relief was assessed on a visual analog scale. Analgesic requirements, complications and the degree of satisfaction were evaluated during the 7 days following surgery. Results: Subjective pain relief was significantly better in Group CE and Group E in comparison with Group C (P < 0.05). Cryoanalgesia provided a better pain score on the 6th and 7th POD than the early postoperative periods. Analgesic requirements were higher in Group C than in the Group CE and Group E during the first POD. The incidence of side effects was similar in Group CE and Group E. Conclusions: If we can reduce the concentration of fentanyl and local anesthetics in combined analgesia of epidural and cryoanalgesia, the disadvantages of each method would be overcome and would be a better method of postthoracotomy pain control.

최근 의료시장에 상용화된 모바일 수술 중 CT(intra-operative computed tomography, iCT)는 수술실 내 이동이 자유로울 뿐만 아니라 수술 후 즉각적인 환자 모니터링이 실시간으로 이루어져 수술 후 환자의 예후 향상과 재수술 확률을 낮출 수 있다. 이동성을 갖춘 iCT 는 편의성과 유용성이 검증되었지만, 이동시 발생될 수 있는 충돌사고의 단점이 존재한다. 따라서, iCT 의 이동시 발생할 수 있는 위험을 최소화 할 수 있는 안전장치가 요구된다. 본 연구에서는 모바일 iCT 의 구동 제어의 편의성과 안전성을 확보 할 수 있는 CT 촬영을 제어하기 위한 리모트 컨트롤러, 이동시 전방 시야를 확보하기 위한 전방 모니터링 카메라 출력, 충돌 위험을 알릴 수 있는 초음파 센서를 통합하는 임베디드 컨트롤러를 개발하고자 한다.
