Woo-Sik Jo,Sung-Hak Lee,Jinmo Koo,Songyi Ryu,Min-Gu Kang,Soon-Young Lim,Seung-Chun Park 한국버섯학회 2017 한국버섯학회지 Vol.15 No.1
Wolfiporia cocos is a well-known traditional medicine in China, Japan, Korea, and other Asian countries owing to its numerous therapeutic properties. With the aim to determine the morphology and genetic characteristics of W. cocosten strains of W. cocos were cultivated in vitro, and subsequently, rapid amplification of polymorphic DNA was performed. To the best of our knowledge, this is the first study to examine the morphology of fruit bodies of W. cocos in Korea. W. cocos were cultured on PDA agar at different temperatures (12, 16, 20, 24, and 28oC) under 12-hour light (600 Lux) / 12-hour dark photoperiod condition for 1 month. Appearance of fruit body was the highest at 28°C condition in all the strains investigated. Honeycomb-like structure on sclerotia was observed in Andong 01, Andong 02, Andong 03, KFRI 1104, KFRI 1105, KFRI 1106, KFRI 1107, KFRI 1108, and ASI 13007 strains of . The KFRI 1103 strain formed cosmos petal-like structure on sclerotia. The average size of basidiospores was recorded as 7.55 μm in height and 3.35 μ in width.

To the best of our knowledge, this is the first study to examine the morphology of fruit bodies of W. cocos in Korea. W. cocos were cultured on PDA agar at different temperatures (12, 16, 20, 24, and $28^{\circ}C$) under 12-hour light (600 Lux) / 12-hour dark photoperiod condition for 1 month. Appearance of fruit body was the highest at $28^{\circ}C$ condition in all the strains investigated. Honeycomb-like structure on sclerotia was observed in Andong 01, Andong 02, Andong 03, KFRI 1104, KFRI 1105, KFRI 1106, KFRI 1107, KFRI 1108, and ASI 13007 strains of. The KFRI 1103 strain formed cosmos petal-like structure on sclerotia. The average size of basidiospores was recorded as $7.55{\mu}m$ in height and $3.35{\mu}$ in width.

<P>The Korean prostrate spurge <I>Euphorbia supina</I> is a weed that has been used in folk medicine in Korea against a variety of diseases. Nine polyphenols were characterized for this plant by using high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) and the results were compared with the literature data. The individual components were validated using the calibration curves of structurally related external standards and quantified for the first time by using the validated method. Correlation coefficients (<I>r</I><SUP>2</SUP>) were >0.9907. The limit of detection and limit of quantification of the method were >0.028 mg/L and 0.094 mg/L, respectively. Recoveries measured at 50 mg/L and 100 mg/L were 76.1–102.8% and 85.2–98.6%, respectively. The total amount of the identified polyphenols was 3352.9 ± 2.8 mg/kg fresh plant. Quercetin and kaempferol derivatives formed 84.8% of the total polyphenols. The antioxidant activities of the flavonoids were evaluated in terms of 1,1-diphenyl-2-picrylhydrazyl and 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) radical cation-scavenging activity, and the reducing power showed a dose-dependent increase. Cell viability was effectively suppressed at polyphenol mixture concentrations >250 mg/L.</P>

집단 음악치료가 ADHD 아동의 자기표현과 자아상에 미치는 효과
문송이 ( Moon¸ Song-yi ),남현우 ( Nam¸ Hyun-woo ) 한국아동교육학회 2021 아동교육 Vol.30 No.4
본 연구는 주의력 결핍 및 과잉행동 장애(ADHD) 아동을 대상으로 집단 음악치료 프로그램을 실시하여 자기표현과 자아상에 미치는 효과를 알아본 것이다. 연구대상은 ADHD로 진단을 받은 초등학교 2-3학년 아동 3명이며, 40분씩 주 2회, 16회기 동안 집단 음악치료 프로그램을 실시하였다. ADHD 아동의 자기표현과 자아상에 미치는 효과를 파악하기 위해 회기별 행동 변화와 사전/사후검사인 그림검사 변화 분석을 했다. 연구 결과, 집단 음악치료 프로그램이 ADHD 아동의 자기표현과 자아상에 긍정적인 효과를 보이는 것으로 나타났다. 본 연구는 주의집중과 충동성에 초점을 맞춘 대부분의 선행 연구들과는 달리 ADHD 아동의 자기표현과 긍정적 자아상 형성을 위해 집단 음악치료 프로그램을 적용하고 효과를 밝혔다는 데 의의가 있다. 학령기 ADHD 아동의 학교생활을 비롯한 다양한 사회적응 문제를 해결하기 위해 자기표현과 자아상에 긍정적인 향상을 도모하는 음악치료 프로그램이 유용하게 활용될 수 있기를 기대해 본다. The purpose of this study is to investigate the effect of group music therapy program on self-expression and self-image for children with attention deficit/hyperactivity disorder(ADHD). The 3 elementary school children diagnosed with ADHD were conducted in the group music therapy program, for 40 minutes, 2 times a week, for 16 sessions. To analyze the effect on children's self-expression and self-image, analysis by session and self-image test were used. As a result of the study, it was found that the self-expression and self-image of children with ADHD after the group music therapy program had a positive effect. Unlike most previous studies focusing on attention and impulsiveness, this study is meaningful in that it applied and revealed a group music therapy program for self-expression and positive self-image formation of ADHD children. It is hoped that a music therapy program that promotes positive improvement in self-expression and self-image of school-age ADHD children will be usefully used to solve various social adaptation problems including school life.
