        혈관내 풍선 확장에 의한 대동맥 차단소생술이 적용된 돼지 복부 장기 조직의 기계적 거동 평가

        왕일재,유지훈,허업,송승환,안효영,송찬희,이치승,유동만,Wang, Il Jae,You, Ji-Hun,Huh, Up,Song, Seunghwan,Ahn, Hyo Young,Song, Chan-Hee,Lee, Chi-Seung,Ryu, Dong-Man 한국재료학회 2020 한국재료학회지 Vol.30 No.4

        Abdominal organs are the most vulnerable body parts under vehicle trauma, and there is high mortality from acute injuries in accidents. There are various ways to reduce this high mortality; one method is Resuscitative Endovascular Balloon Occlusion of the Aorta, which has recently become very popular as a minimally invasive alternative in the emergent management of patients with non-compressible hemorrhages below the diaphragm. However, high safety factor for patients is applied in actual clinical practice because there is no exact standard for the operating time. Therefore, in this study, the effects of the mechanical behavior of organ tissues for the duodenum, kidney, and liver on the operating time of Resuscitative Endovascular Balloon Occlusion of the Aorta is investigated in order to obtain data needed to establish standards of operating time. In characteristic analysis of organ tissues, uniaxial tensile test and compression test are conducted according to the operating time.

        치매안심센터를 이용하는 지역사회 노인들의 가상현실기반 뇌채움 인지훈련이 인지기능에 미치는 효과

        김두리(Kim Du-Ri),김권민(Kim Gwon-Min),송승환(Song Seung Hwan),허업(Huh Up),장재혁(Chang Jae-Hyeok),탁영진(Tak Young-Jin),박종환(Park Jong-Hwan) 고령자치매작업치료학회 2020 고령자.치매작업치료학회지 Vol.14 No.2

        목적: 본 연구는 치매안심센터를 이용하는 지역사회 노인을 대상으로 가상현실기반 뇌채움 인지훈련이 인지기능에 미치는 효과를 알아보고자 한다. 연구방법: 치매안심센터를 이용하는 지역사회 노인 10명을 대상으로 주 2회 12주간, 회당 50분씩 가상현실기반 뇌채움 인지훈련을 시행하였다. 인지기능의 효과를 알아보기 위해 중재 전과 후의 Korean Mini-Mental State Examination(K-MMSE), Korean Version of Montreal Cognitive Assessment(K-MOCA), Digit Span Test(DST), Controlled Oral Word Association Test(COWAT), Digit Symbol Coding(DSC), Korean-Color Word Stroop Test(K-CWST) 평가를 시행하였다. 연구결과: 가상현실기반 뇌채움 인지훈련 중재 전과 후의 인지기능을 비교한 결과 K-MMSE(P=.019)와 Stroop Word(P=.011) 평가에서 통계적으로 유의한 증가가 나타났다. 결론: 가상현실기반 뇌채움 인지훈련은 지역사회 노인들에게 실제와 같은 일상생활활동의 훈련 환경을 조성하여 가상현실이라는 공간에서 만족감을 얻어 경험하고 행동할 수 있게 한다. 또한, 재미와 흥미 유발을 통한 집중력 증진이 치매예방 및 인지기능 향상에 도움을 주어 치매안심센터를 이용하는 지역사회 노인들에게 적절한 중재 프로그램으로써 적용해볼 수 있다. Objective : This study was conducted to investigate the effects of virtual reality-based cognitive training on elderly adults in the community who use dementia care center. Methods : The subjects were 10 elderly adults in the community who use the dementia care center were provided with virtual reality-based cognitive training twice a week for 12 weeks, 50 minutes per session. To identify the effects of cognitive functioning was evaluated before and after the intervention for comparison using the K-MMSE, K-MOCA, DST, COWAT, DSC, K-CWST. Results : A comparison of changes in cognitive function before and after intervention of the virtual reality-based cognitive training, improved statistically significant in K-MMSE score(P=.019) and Stroop Word score(P=.011). Conclusion : Virtual reality-based cognitive training allows elderly adults in the community to experience and act with satisfaction in the space of virtual reality by creating a training environment for daily living activities like real life. It also suggests that the enhancement of concentration through the inducement of fun and interest can help prevent dementia and improve cognitive functions, which can be applied as an appropriate intervention program for elderly adults in the community who use the dementia care center.

        외상성 횡격막 손상의 치료

        Purpose: Diaphragmatic rupture following trauma is often an associated and missed injury. This report is about our experience with treating traumatic diaphragmatic rupture (TDR). Methods: From January 2007 to September 2012, 18 patients who had a diaphragmatic rupture due to blunt trauma or penetrating injury underwent an operation for diaphragmatic rupture at our hospital. We retrospectively reviewed their medical records, including demographic factors, initial vital signs, associated injuries, interval between trauma and diagnosis, injured side of the diaphragm, diagnostic tools, surgical method or approaches, operative time, herniated organs, complications, and mortality. Results: The average age of the patients was 43 years, and 16 patients were male. Causes of trauma included motor vehicle crashes (n=7), falls (n=7), and stab wounds (n=5). The TDR was right-sided in 6 patients and left-sided in 12. The diagnosis was made by using a chest X-ray (n=3), and thorax or upper abdominal computed tomography (n=15). Ten(10) patients were diagnosed within 12 hours. A thoracotomy was performed in 8 patients, a video-assisted thoracoscopic surgery in 4 patients, a laparotomy in 3 patients, and a sternotomy in one patient. Herniated organs were the omentum (n=11), stomach (n=8), spleen and colon (n=6), and liver (n=6). Eighteen diaphragmatic injuries were repaired primarily. Seven patients underwent ventilator care, and two of them had pneumonia and acute respiratory distress syndrome. There were no operative mortalities. Conclusion: Early diagnosis and surgical treatment determine the successful management of TDR with or without the herniation of abdominal organs. The surgical approach to TDR is chosen based on accompanying organ injuries and the injured side. (J Trauma Inj 2012;25:217-222)
