Objectives:The reliability and validity of the Korean version of Young Mania Rating Scale (K-YMRS) were examined in the Korean patients with major psychosis. Methods:One hundred and twenty inpatients diagnosed as major psychosis by DSM-IV criteria were assessed with both KYMRS and expanded Brief Psychiatric Rating Scale (BPRS-E) during the first 3 days in hospital and after 4-week treatment. Results:The Cronbach’s alpha coefficient of K-YMRS was 0.73. The inter-rater reliabilities of total score (r=0.93, p=0.000) and individual item scores were high (r=0.65-0.96, p=0.000). The correlations of each items of K-YMRS with total score were statistically significant (r=0.35-0.78, p=0.000) except for the “insight” item. The principal component analysis for KYMRS produced three factors;a) mood and vegetative symptoms, b) behavioral symptoms, and c) thought content and insight. The total scores of K-YMRS showed a significant correlation with the manic-excitement factor scores of BPRS-E at baseline and after 4-week treatment (r=0.82, r=0.72, respectively, p=0.000). The discriminant function analysis showed that manic (n=43) and non-manic patients (n=73) were discriminated 73.7% correctly by K-YMRS total score (p=0.01). The change of the total score of K-YMRS after 4-week treatment in manic patients was significantly greater than that in non-manic patients (p=0.000). Conclusions:K-YMRS was demonstrated to have good reliability and validity for measuring the severity of manic symptoms. It is expected that K-YMRS will be a useful tool for assessing mania symptoms in Korea.

Mesenchymal stem cell (MSC) and mitochondria are important materials for cell therapy products. In this study, we carried out to compare yields of mitochondria in mesenchymal stem cell isolated from various tissue. The liver, muscle and adipose tissues were removed from rat. Mesenchymal stem cells were isolated using trypsin. Mitochondria were isolated in cultured MSC by cell fractionation. Absorbance of mitochondrial DNA at 260 nm with spectrophotometer to measure indirectly the amount of mitochondria. In these results, liver tissue contained a lot of MSC and mitochondria compared with other tissues. The liver is an optimized tissue for harvest of mitochondria.

최근 한국어교육 현장은 코로나바이러스감염증-19의 영향으로 수업 형태에 변화가 생겼다. 이러한 변화 속에서 직접 동영상 온라인 수업을 진행한 교사들의 수업에 대한 경험, 인식, 만족도 등에 대한 연구는 앞으로의 수업 방향 및 현실적 대응책을 제시하는 데에 도움이 될 것이다. 이에, 본 연구는 온라인 동영상 수업으로 진행된 한국어 수업에 대한 교사의 인식을 확인하고자, 대전 소재의 P대학교 한국어교육기관의 교사 22명을 대상으로 두 차례에 걸쳐 조사·분석하였다. 설문 결과, 교사들의 대부분이 온라인 동영상 수업에 대해 부정적으로 인식하고 있 음을 확인하였고, 이를 해결하기 위해 대학(기관) 차원에서의 협조가 시급함을 알 수 있었다. 본 설문 조사 결과는 앞으로 진행될 한국어 온라인 수업 운영 시 도움이 될 만한 기초 자료로서 의의를 가진다.

There have been vast amount studies regarding immunologic dysregulation in schizophrenia. The mechanism of immune pathogenesis in schizophrenia still is unclear, even though various immune dysfunction have been reported. We endeavored to report on two major hypothesis on immunologic dysregulation in schizophrenia, the infection hypothesis and autoimmune hypothesis. We went on to focus on the autoimmune hypothesis, which has received the most attention over the years. We explored the accumulated data and the rational behind the autoimmune hypothesis and the implications of the autoimmune hypothesis for future research in the pathogenesis of schizophrenia.
