이다솔(Lee, Da-Sol),최윤서(Choi Yoon-Seo),이혜진(Lee, Hye-Jin) 대한고령친화산업학회 2018 대한고령친화산업학회지 Vol.10 No.1

본 연구의 목적은 과제지향적 훈련을 통해 환자 스스로 과제를 선택하고 수행하였을 때 환자의 삶의 질과 일상생활활동에 미치는 효과와 치료 만족도를 알아보고자 한다. 본 연구는 2017년 8월부터 2017년 10월까지 P, W시 병원에 입원하여 작업치료를 받는 뇌졸중 환자 46명을 대상으로 환자중심 과제지향적 훈련군과 전통적 작업치료군으로 각각 8주간 주5회 1회 15분씩 실시하였다. 각 치료효과의 결과를 확인하기 위해 SPSS 18.0 version 프로그램을 사용하여 빈도분석, 독립표본 t검정, 대응표본 t검정을 이용하였다. 과제지향적 훈련과 전통 작업치료의 유의미한 차이는 없었지만, 두 치료 모두 뇌졸중 환자의 삶의 질과 일상생활활동을 향상시키는데 효과적이었다. 특히, 환자의 만족도를 향상시키는데 있어서는 과제지향적 훈련이 전통 작업치료보다 효과적인 것으로 나타났다. 과제지향적 훈련과 전통 작업치료 모두 뇌졸중 환자의 삶의 질과 일상생활활동을 향상 시키고, 환자중심 과제지향적 훈련은 뇌졸중 환자의 치료 만족도를 향상시키는데 큰 도움이 된다. 따라서 과제지향적 훈련은 치료의 긍정적인 효과를 기대할 수 있을 것이다. Objective : The purpose of this study is to investigate the effects of patient’s self-selecting and performing tasks through task-oriented training on patient’s quality of life, daily activities, and treatment satisfaction. Method : The purpose of this study is to investigate the effects of patient’s self-selecting and performing tasks through task-oriented training on patient’s quality of life, daily activities, and treatment satisfaction. Result : Although there was no significant difference between task-oriented training and traditional occupational therapy, both treatment methods were effective in improving the quality of life and daily activities of stroke patients. In particular, task-oriented training was more effective than traditional occupational therapy in improving patient satisfaction. Conclusion : Both task-oriented training and traditional occupational therapy improve patient’s quality of life and daily activities. Especially, patient-centered task-oriented training program is very helpful in improving treatment satisfaction in stroke patients. Therefore, task-oriented training program can be expected to have a positive effect of treatment.

임소현(So Hyean Lim),이혁재(Hyeok Jae Lee),이우연(Woo Yeon Lee),최윤서(Yoon Seo Choi),정훈(Hoon Chung) 반려동물연구학회 2021 Animalia Vol.3 No.1

본 연구는 물의 형태에 따른 여러 견종들의 선호도에 대해 알아보았다. 실험에 사용한 견종으로는 Golden Retriever(2018년생, 중성화O, 여) 1마리, Shih Tzu(2011년생, 중성화X, 여/ 2013년생, 중성화O, 남) 2마리, Maltese(2013년생, 중성화O, 남) 1마리, schnauzer(2011년생, 중성화X, 남) 1마리이다. 실험은 총 2가지이며 실험 A는 각각의 온도와 색깔을 매칭, 실험 B는 각각의 향과 위치를 매칭하여 학습을 진행한 후, 각각의 독립변인을 동일하게 하였을 때에도 견종이 반복적으로 선택하던 색상과 위치를 선택하는지 관찰하였다. 동물행동과학 연구실과 각 연구원의 집에서 실험이 진행되었으며, 산책 및 노즈워크 이후 물을 섭취하는 행동을 영상으로 기록하였다. 견종 1마리당 하나의 실험에 대해 12회의 영상이 기록되었으며, 이에 대해 최초선택, 반복선택, 평균 음수량을 기록하였다. 영상분석 결과 모든 견종에게서 22 ℃ 이하의 온도와 단향을 선호하는 것으로 나타났다. 본 연구결과는 반려견의 원활한 음수 섭취를 도울 수 있는 기초자료가 될 것으로 예상된다. This study investigated the preferences of various breeds according to the type of water. The dog species used in the experiment were Golden Retriever (born in 2018, neutralized O, female), Shih Tzu (born in 2011, neutralized X), female / 2013 neutralized O, male), Maltese (born in 2013, neutralized O, male), and schnauzer (born in 2011, neutralized X). There are a total of two experiments, and Experiment A matches each temperature and color, and Experiment B matches each scent and location to observe whether the dog selects the color and location repeatedly even when each independent variable is the same. Experiments were conducted in the animal behavior science laboratory and at the homes of each researcher, and the behavior of drinking water after walking and nose work was recorded as a video. Twelve images were recorded for one experiment per breed, and the initial selection, repetitive selection, and average negative quantity were recorded. As a result of image analysis, it was found that all breeds prefer temperatures and uniases below 22°C. The results of this study are expected to be basic data to help dogs consume negative water smoothly.

다중램프 구동을 위한 집적화된 전류평형 트랜스포머

박현서(Hyun-Seo Park),최윤(Yoon Choi),홍성수(Sung-Soo Hong),한상규(Sang-Kyoo Han),노정욱(Chung-Wook Roh) 전력전자학회 2010 전력전자학술대회 논문집 Vol.2010 No.7

본 논문에서는 새로운 구조의 전류평형 트랜스포머를 제안한다. 기존 방식은 하나의 CCFL(Cold Cathode Fluorescent Lamp)당 하나의 밸런스 코일이 필요한데 반해, 제안된 방식은 4 개의 CCFL당 하나의 밸런스 코일로 구동하는 방식이다. 따라서 소자수가 감소하고 전원 구동부의 부피가 저감되는 효과가 있다. 본 논문에서 제안된 밸런스 코일을 Gyrator 모델링을 통해 이론적으로 분석하였으며, 모의실험을 통해 46인치 LCD TV용 인버터에 적용하여 동작의 타당성을 검증하였다.

We described the effects on the antifungal agent by the co-culture elicitor of Colletotrichum acutatum and callus of Lactuca sativa. The callus culture were induced from seed germination of Lactuca sativa in MS medium with 0.05 ㎎/ℓ IAA and 0.3 ㎎/ℓ kinetin. The seed germination of Lactuca sativa observed after 3 days and the differentiation of callus tissue was induced after 8 days since starting of callus culture. The fungal elicitor made by Colletotrichum acutatum with PDB medium. In order to produce antifungal agent on the anthracnose, fungal elicitor and callus tissue were cultivated by co-culture for 7 days. The result, it produced a chitinase and a phytoalexin those are antifungal agent of protein and non-protein type. Each sample of daily like extracellular material especially had chitinase activity and increased enzyme activity with changing pH and concentration of protein as the culture progressed. The antifungal activities on final samples were examined by bioassay with Colletotrichum acutatum, Fusarium oxysporum, Fusarium solani, Fusarium moniliforme and Sclerotia rolfsii. The result, inhibition rate on fungi to bring plant disease showed different data according to the kinds of sample and concentrations. In case of Fusarium moniliforme was inhibited the growth of mycelium in the sample of extracelluar material on the other hand Colletotrichum acutatum was inhibited growth in the sample of intracellular material. As a result, co-culture with fungal elicitor and callus tissue brings a defense system and a hypersensitive response in the plant cell and induces to synthesis antifungal agent as a chitinase and a phytoalexin.

흰쥐 횡경막 신경근표본에서 Mivacurium과 Succinyl-choline의 근이완 작용에 대한 Neostigmine, Pyridostigmine, Edrophonium, Galanthamine 및 Pseudocholinesterase의 반전효과

한성민,최윤,양홍석,김성렬,서병태,조삼순,윤시네 대한마취과학회 2000 Korean Journal of Anesthesiology Vol.39 No.2

Background: The hydrolysis of mivacurium and succinylcholine is impaired in the presence of defects of pseudocholinesterase. Clinical reports are conflicting as to the utility of anticholinesterases, in the reversal of mivacurium- or succinylcholine- induced paralysis. In this study, the role of exogenous bovine pseudocholinesterases (BpChE) and/or neostigmine, pyridostigmine, edrophonium or galanthamine in the reversal of mivacurium- or succinylcholine-induced paralysis, were investigated with the rat phrenic nerve-diaphragm preparation. Methods: Ninety five Sprague-Dawley rats (200 g, male) were divided into 14 groups (n = 10). The phrenic nerve-diaphragm preparation mounted in a bath containing oxygenated Krebs' solution. Twitch response from diaphragmatic muscle evoked by phrenic nerve stimulation were measured. After stabilization of the twitch responses, mivacurium (0.1 ㎍/mlml) or succinylcholine (0.1 ㎍/ml) was administered incrementally in the preparation to obtain more than 95% twitch inhibition. BpE (0.1, 1.0 u/ml), and/or neostigmine (0.1, 1.0 ㎍/ml), pyridostigmine (0.5, 5 ㎍/ml), edrophonium (0.01, 0.1 ㎍/ml) or galanthamine (0.1, 1.0 ㎍/ml) were added for the reversal of mivacurium- and/or succinylcholine-induced block in each group and the twitch responses (0.1 Hz) were monitored for 60 min. The effect of BpChE (0.1 u/ml), in combination with each of the above four anticholinesterases at lower concentrations also were examined. Twitch heights more than 75% was considered an adequate reversal. Results: BpChE 0.1 and 1.0 u/ml were effective in reversal of mivacurium-induced paralysis. When anticholinestrases were added, there was no effective improvement of twitch height at the end of 60 minutes. In succinylcholine-induced paralysis, BpChE was effective for reversal, but when anticholinesterases were added, BpChE potency was inhibited. Conclusions: BpChE will reverse mivacurium-induced block more effectively than anticholinesterase. BpChE is effective in reversing succinylcholine block. The additionanticholinesterases inhibits the activity of pseudocholinesterase.
