      • 교차소뇌해리현상을 보이는 환자는 새로운 운동학습이 가능 한가? : 단일사례연구

        남희윤(Hee Yun Nam),이성아(Seong A Lee),임연주(Yeon Ju Lim),김원령(Won Ryeong Kim) 한국인지운동치료연구회 2011 한국신경인지재활치료학회지 Vol.3 No.1

        Objective : This study is aimed at looking at how the new motor learning is going or not by comparing the patient showing the phenomenon of crossed cerebellar diaschisis with a normal person through darts-throwing. Methods : This study selected a 69-year-old man with the phenomenon of crossed cerebellar diaschisis and another 69-year-old man judged as neurologically normal as its study subjects. The process of this experiment consisted of Checking the distance from the bull s eye with a dot when two men playing darts. Results : As a result of the study, there appeared no significant difference between experimental conditions in the healthy man while there appeared a significant difference in experimental condition 1-2(p=.019), and 1-3(p=.019), but there appeared no significant difference in experiment 2-3. Looking at the results of the comparison between the healthy man and patient by experimental condition, there appeared a significant difference in all experimental condition. In the result of the analysis of variance between the three experimental conditions, there appeared no significant difference in the healthy man and the patient. Conclusion : Through a simple experiment, this study was able to discover that it s difficult for a patient with crossed cerebellar diaschisis to take motor learning requiring new movements.

        BMS의 위험우선순위 분석과 기능안전을 고려한 설계

        김운동,이순구,강대근 대한임베디드공학회 2021 대한임베디드공학회논문지 Vol.16 No.2

        In recent years, as ESS has become very popular, BMS related electric fires have occurring frequently. In this research we performed analysis of risk priority number (RPN) using Failure Mode and Effects Analysis (FMEA) technique to analyze the safety of BMS, which accounts for the most part in ESS electric fires. And the functional safety concept was used to eliminate or reduce failure modes that may cause overvoltage, overcurrent, and overheating for higher risk priorities of the analyzed BMS. The BMS hardware was redesigned so that the safety mechanism works for the high-priority risk modes, and the main firmware procedures were designed to control the battery against potential malfunctions. And we implemented the improved BMS hardware and experimentally verified that the safety mechanism works as designed. The test results have confirmed that the safety mechanism works normally and the battery can be controlled even if overvoltage, overcurrent and overheating occurs in the BMS, or major firmware procedures malfunction. Therefore we are confident that electric fires related to ESS can be prevented in advance by analyzing the safety of BMS in the way we used in this research to find high-priority risk factors and applying the concept of safety functions to the hardware and software design of BMS.

        외상성 뇌손상 환자에서 실행증의 인지운동치료 효과 : 단일사례연구

        남희윤(Hee-Yun Nam),최은희(Eun-Hee Choi) 한국인지운동치료협회 2009 한국신경인지재활치료학회지 Vol.1 No.1

        목 적 본 논문은 외상성 뇌손상 환자에게 적용한 실행증을 위한 인지운동치료가 인지력 및 일상생활수행에 미치는 효과를 알아보는 것이다. 방 법 본 연구의 대상자는 오토바이 사고로 인해 사지마비가 있는 51세 남자환자로 2009년 03월 17일부터 2009년 4월 30일까지 약 6주간 인지운동치료를 적용하였다. 적용하여 실시한 인지운동치료로는 실행 기능을 개선시키기 위한 주의 집중 훈련, 신체의 인식훈련 및 정보를 변환(2차원, 3차원, 운동각, 체성감각)하는 훈련이다. 결 과 실행 증상을 보여 일상생활에 어려움을 보이던 환자에게 인지운동치료를 6주간 시행한 결과 MMSE-K는 13점에서 24점으로 11점 향상되었으며, AMPS에서는 운동기술(-1.87에서 0.27로 2.14 logit의 변화)과, 처리기술(-2.97에서 -0.42로 2.55 logit의 변화)에서 점수의 향상이 있었다. 결 론 실행 증상을 보이는 환자에게 인지운동치료에서 제시하는 치료 기법을 적용한 후 인지기능과 일상 생활 수행능력의 개선에서 긍정적인 효과가 있었다. Objective : This paper is to identify effects on their cognitive functions and activities of daily living after applying Cognitive Therapeutic Exercise for functional recovery of patients with Apraxia. Methods : The recipient of this study was a male patient, who is 51 years old with quadriplegia due to a motorcycle accident and has got the Cognitive Therapeutic Exercise for approximately six weeks from March 17, 2009 till April 30, 2009. The Cognitive Therapeutic Exercise consisted of attention, body awareness and information transformation (2-dimensional, 3-dimensional, kinesthesia, and somatosensory) training executed to improve Apraxia of this patient was conducted. Results : As a result after applying the Cognitive Therapeutic Exercise for 6 weeks to the patient who shows a lot of difficulties in activities of daily living due to the symptom of Apraxia, MMSE-K has been enhanced form 13 points to 24 points, and the motor and processing skills of AMPS have been improved from -1.87 to 0.27 (there has been a positive change by 2.14 logit) and from -2.97 to -0.42 (there has been a positive change by 2.55 logit) respectively. Run to the symptoms the patient is presented in exercise therapy and cognitive therapy techniques applied to improve ability to perform daily life had a positive effect on. Conclusion : After applying the therapy that the Cognitive Therapeutic Exercise suggests to the patient who shows the symptom of Apraxia, there have been positive effects in terms of improving cognitive function and the ability to carry on activities of daily living.

      • 편마비 환자의 신체인식양상 훈련이 신체기능향상에 미치는 효과

        임연주(Yeon Ju Lim),남희윤(Hee Yun Nam) 한국인지운동치료연구회 2010 한국신경인지재활치료학회지 Vol.2 No.1

        Objective : We tried to check the effect to the physical function and activities of daily living through applying the physical recognition patterns training of the cognition therapy exercise(CTE) for the patient who got hemiplegia. Methods : The subject of this research is 69 aged woman who got diagnosis of left side hemiplegia through the cerebral infarction on June. 1. 2010. We applied the physical recognition patterns training of Cognition Therapy Exercise(CTE) to the subject 1 time a day 45 minutes during the 13 weeks, from July. 27. 2010 to October. 29. 2010. Results : After the 13 weeks of the early valuation, the result of revaluation is as follows. From 27/7 to 31/28 on MFT, from 55/0 to 67/49 on box&block test, from 13/0 to 14/7 on purdue pegboard test and before the training, paralytic side can t be evaluated on every clause but after 13 weeks, all clause is improved. On Activities of Daily Living test, 59 pt. is improved from 25 to 84 so almost every part can perform separately. Occupational performance measure is also improved from 14 to 27 on total performance pt. and from 10 to 22 on total satisfaction pt. The cognitive therapeutic exercise profile showed the improvement in pathological characteristics, especially in recognition aspect, attention aspect, image aspect, language aspect, and learning aspect. Conclusion : Therefore, physical recognition patterns training for hemiplegia patient can get positive effect on physical function and activities of daily living.
