Modern acupuncture-like stimulation methods: a literature review
전민호,김영민,김재욱 한국한의학연구원 2015 Integrative Medicine Research Vol.4 No.4
Acupuncture therapy has been proved to be effective for diverse diseases, symptoms, and conditions in numerous clinical trials. The growing popularity of acupuncture therapy has triggered the development of modern acupuncture-like stimulation devices (ASDs), which are equivalent or superior to manual acupuncture with respect to safety, decreased risk of infection, and facilitation of clinical trials. Here, we aim to summarize the research on modern ASDs, with a focus on featured devices undergoing active research and their effectiveness and target symptoms, along with annual publication rates. We searched the popular electronic databases Medline, PubMed, the Cochrane Library, and Web of Science, and analyzed English-language studies on humans. Thereby, a total of 728 studies were identified, of which 195 studies met our inclusion criteria. Electrical stimulators were found to be the earliest and most widely studied devices (133 articles), followed by laser (44 articles), magnetic (16 articles), and ultrasound (2 articles) stimulators. A total of 114 studies used randomized controlled trials, and 109 studies reported therapeutic benefits. The majority of the studies (32%) focused on analgesia and pain-relief effects, followed by effects on brain activity (16%). All types of the reviewed ASDs were associated with increasing annual publication trends; specifically, the annual growth in publications regarding noninvasive stimulation methods was more rapid than that regarding invasive methods. Based on this observation, we anticipate that the noninvasive or minimally invasive ASDs will become more popular in acupuncture therapy.
소형 발전기의 에너지 절약을 위한 전력관리 시스템 개발
전민호,오창헌,Jeon, Min-Ho,Oh, Chang-Hyun 한국정보통신학회 2012 한국정보통신학회논문지 Vol.16 No.12
본 논문에서는 2대 이상의 소형 발전기를 사용하는 환경에서 부하의 전력 소비량을 이용하여 에너지를 절약하는 전력 관리 시스템을 제안하고 개발하였다. 고속의 하드웨어 플로팅 포인트 연산처리가 가능한 TI사의 TMS320C6713 DSP 칩을 사용하여 하드웨어를 구성하였으며, 시리얼 통신을 이용하여 모니터링 PC와 통신하게 하였다. 모니터링 PC에서 수동제어가 가능하도록 하였으며, DSP main board에서 CT/PT센서로 수집한 데이터를 이용하여 자동적으로 발전기를 on/off 할 수 있도록 구현하였다. 실험 결과 본 논문에서 제안한 전력 관리 시스템이 이상 없이 동작하는 것을 확인할 수 있었으며, 부하의 전력사용량을 이용하여 에너지를 절약하는 알고리즘을 적용하였을 경우 소형 발전기 2대를 지속적으로 사용할 때 보다 더욱 오래 전력을 공급하는 것을 알 수 있었다. In this paper, an electricity management system, which saves energy by utilizing electricity consumption of load from an environment that uses at least two compact generators, is proposed and developed. A hardware is constructed by using TMS320C6713 DSP chip made by TI that is capable of high speed hardware floating point processing while serial communication is used for communication with a monitoring PC. Manual control is made possible from the monitoring PC and automatic on/off is enabled in the generator by using data collected by CT/PT sensor from the DSP mainboard. Test results confirm that the electricity management system proposed in this study functions without abnormality. The application of an algorithm that saves energy by using electricity consumption of load also allows for a longer supply of electricity compared to continuously using two compact generators.
