김병훈,권오병,마병철,강미란,권무식 성균관대학교 생명과학자원연구소 1996 生命資源科學硏究 Vol.3 No.1

Chinese cabbage(Brassica campestris subsp pekinensis) useful for making a traditional Korean food, Kimchi, has been considered as the most important vegetable in Korea. In order to supply large quantity of chinese cabbage to the consumer, the mass cultivation is demanded. However, the mass production has been faced to serious problem due to fungal, bacterial and/or viral infections. It has been reported that the viral infections are the worst phatogeruc causes in a number of plants. In the chinese cabbage, turnip mosaic virus(TuMV) is the most serious pathogen. Five different strains of TuMV(Cl, C2, C3, C4, and C5) were identified in the world. We are reporting two strains(C4, C5) purified from Brassica nigra. They are all filamentous on electron micrographs. The TuMV C4 is about 1,300nm long, whereas the C5 is about 1,200nm long in average. They are larger than those reported previously(680-900nm). They will be used to produce monoclonal antibodies against the TuMV coat proteins. The antibodies arc required to develop a sensitive and specific screening methods for the TuMV infected plants.

Objectives : This study was designed to evaluate the relationship between quality of life (QOL) and psycho-socio-spiritual characteristics in male patients with alcohol dependence. Methods : The sample consisted of 109 men with alcohol dependence defined by DSM-IV criteria. We assessed QOL by the WHO QOL assessment instrument-BREF (WHOQOL) and SmithKline Beecham QOL (SBQOL). Sociodemographic and alcohol related data were collected, and 7 questionnaires were administered : MAST, BDI, STAI, Drinker Inventory of Consequences (DrInC), Scale of Social Support (SSS), Religious Beliefs and Behaviors (RBB) and Spiritual Well-being Scale (SWBS). The correlations between each QOL score and other variables were examined, and stepwise multiple regression analysis was performed. Results : The WHOQOL score positively correlated with education level, SSS (support) and RBB and negatively correlated with MAST, DrInC, BDI, STAI (trait) and SSS (conflict) scores. In stepwise regression analysis, the scores on the STAl and BDI contributed to the score on the WHOOOL. The SBQOL score correlated with the income level, and negatively correlated with BDI and STAI score. STAI score was a weak predictor of SBQOL score. Conclusion : The significant predictors of QOL in patients with alcohol dependence were psychological factors such as anxiety and depression.

This study was conducted to investigate the vitamin D status and to determine the association between serum 25-hydroxyvitamin D [25(OH)D] concentrations and consumption frequencies of vitamin D rich foods in Korean adults and older adults. Methods: Subjects were 10,374 adults and 2,792 older adults participating in the 2008- 2009 Korea National Health and Nutrition Examination Survey (KNHANES). Consumption frequencies of vitamin D rich foods were estimated by using a qualitative food frequency questionnaire (FFQ). Eleven food items such as beef, egg, mackerel, tuna, yellow corvina, pollack, anchovy, mushroom, milk, yogurt, and ice cream were selected as vitamin D rich foods based on previous research. Results: The proportions of deficiency (< 12 ng/mL), inadequacy (12-20 ng/mL) and sufficiency (≥ 20 ng/mL) of serum 25(OH)D concentrations from June to November and December to May in adults were 8.8%, 42.3%, 48.8%, and 28.2%, 52.8%, 19.1%, respectively. The proportions of deficiency, inadequacy and sufficiency of serum 25 (OH)D concentrations from June to November and December to May in older adults were 10.1%, 32.4%, 57.5%, and 24.1%, 45.4%, 30.5%, respectively. The mean serum 25(OH)D concentrations in adults were positively related to the consumption frequencies of mackerel, anchovy, all fish, milk and milk·dairy products. The mean serum 25(OH)D concentrations in older adults were positively related to the consumption frequencies of yellow corvina and negatively related to the consumption frequencies of ice cream. Conclusions: Our results suggest that Korean adults were more deficient in serum 25(OH)D concentrations than older adults. The consumption of vitamin D rich foods may affect vitamin D status in Korean adults. Further studies are required to confirm these findings.

유치원아 부모의 사회계층에 따른 자녀교육관에 대한 세대간 비교연구

오혜진,주경란 한국아동교육학회 2004 아동교육 Vol.13 No.2

본 연구는 보다 효과적인 부모교육을 위한 기초 자료를 제공하기 위하여, 만 5-6세 유치원아 부모들의 자녀교육관을 세대간, 성별에 따라 비교 연구하였다. 상, 중, 하 계층에 따라 3곳의 유치원을 선정하고 만 5, 6세 유아들의 부모들을 대상으로 본인의 자녀교육관과 부모로부터 받은 자녀교육관, 과거 교육환경에 대한 만족도를 설문 조사하였다. 설문조사 결과 점수를 통하여 부모들의 설문을 각 계층별로 우선 구분하여 2세대와 1세대의 자녀교육관을 비교하였다. 또한 2세대의 과거 교육경험에 대한 만족도를 비교연구하였다. 그 결과, 첫째로 2세대의 사회계층에 따른 1세대의 자녀교육관은 각 계층간 유의한 차이가 있는 것으로 나타났다. 둘째, 2세대의 사회계층의 따른 자녀교육관을 비교했을 때, 1세대에 비해 2세대의 자녀교육관이 다소 유아중심 교육관에 가까운 것을 알 수 있었다. 셋째, 2세대의 성별에 따른 자녀교육관은 큰 차이는 없었으나, 아버지가 어머니보다 다소 유아중심 교육관에 가까운 것을 알 수 있었다. 반면, 과거 교육환경 만족도 차이에 있어서는 아버지보다 어머니의 만족도가 높은 것을 확인할 수 있었다. 연구결과들을 바탕으로 보다 효과적인 부모교육 프로그램 개발을 위한 제안점이 제시되었다. The purpose of this study was to provide basic informations for more effective parent education through an inter-generational comparative investigation on the opinions of child-rearing practices according to the Social Economic Status of kindergarteners' parents.

Antidepressant Effects of <i>Vaccinium bracteatum</i> via Protection Against Hydrogen Peroxide-Induced Oxidative Stress and Apoptosis

Oh, Dool-Ri,Kim, Yujin,Choi, Eun-Jin,Jo, Ara,Shin, Jawon,Kang, Huwon,Lee, Seul-Gi,Kim, Jaeyong,Kim, Young Ran,Choi, Chul Yung World Scientific Publishing Company 2018 The American journal of Chinese medicine Vol.46 No.7

<P>The present study evaluates the anti-oxidative stress activity of <I>Vaccinium bracteatum</I> Thunb. fruit extract (VBFW) to identify the mechanisms responsible for its antidepressant-like effects. To evaluate the antidepressant and anti-oxidant effects of VBFW, malondialdehyde (MDA), serotonin transporter (SERT), and monoamine oxidase A (MAO-A) levels were measured in a mouse model of chronic restraint stress (CRS). The underlying mechanisms preventing oxidative stress and neuronal apoptosis were investigated using <I>in vitro</I> models of hydrogen peroxide (H<SUB>2</SUB>O<TEX>$ _{2})$</TEX>-induced neuronal damage. The results showed that VBFW treatment (200<TEX>$ \,$</TEX>mg/kg) significantly reduced MDA, SERT, and MAO-A levels in the prefrontal cortex of CRS mice. Furthermore, VBFW (30<TEX>$ \,$</TEX><TEX>$ \mu $</TEX>g/mL) exhibited protective effects against H<SUB>2</SUB>O<SUB>2</SUB>-induced cell death via inhibition of the H<SUB>2</SUB>O<SUB>2</SUB>-induced increase in Bax and decrease in Bcl-2 levels within the mitochondria of SH-SY5Y cells. Furthermore, VBFW (10 and 30<TEX>$ \,$</TEX><TEX>$ \mu $</TEX>g/mL) exerted protective effects against H<SUB>2</SUB>O<SUB>2</SUB>-induced cell death through inhibition of key mitochondria-associated apoptotic proteins such as cytochrome c, caspase-3 and PARP. Additionally, VBFW (10 and 30<TEX>$ \,$</TEX><TEX>$ \mu $</TEX>g/mL) could improve the activity of anti-oxidant enzymes (such as SOD and catalase) in H<SUB>2</SUB>O<SUB>2</SUB>-treated SH-SY5Y cells. These results suggest that the antidepressant and anti-oxidant effects of VBFW might be mediated by the regulation of SERT and MAO-A, and possibly associated with regulation of oxidative stress-induced apoptosis.</P>

훈민정음 초성 체계의 정밀전사의식

오정란 光云大學校 1994 인문사회과학논문집 Vol.23 No.-

The phonetic value and phonological status of the literal system of Hunminjungum(訓民正音), which has been the major topic of dispute in the history of Korean phonology, should be reexamined on the ground that Hunminjungum has the multi-functional ability of phonetic symbol. By multi-functional ability of phonetic symbol we mean that the literal system is intentionally created to fulfill the various kinds of perfect phonetic representations as follows : (1) representation of pure Korean language, (2) representations of borrowed language of foreign origin-Chinese orgin Korean language, (3) representations of foreign language-Chinese language. First, Yongbieocheon-ka(龍飛御天歌)·Samganghaengsil-to(三綱行實圖) etc., completed contemporarily with Hunminjungum, show that Hunminjungum was used for the representation of pure Korean language. Second, Tongkukjungun(東國正韻) shows that Hunminjungum was also used for the representation of borrowed language of foreign origin. Finally, Hongmujungunyeokhun (洪武正韻譯訓) shows that Hunminjungum was used for representation fo the foreign language. This various and perfect phonetic ablility fo Hunminjungum is presented in the form of the narrow transcription, in which even the phonetic forms are transcrived in the Korean phonetic representation. When we compare the onset system of Hunminjungum with that of Tongkukjungun, Hongmujungunyeokhun etc., we can say that kakja-piongse(各自竝書, on set parallel sound), panchium (半齒音, semi-dental sound), sunkyungum(脣輕音, light labial sound) were not the phonological representations but the allophones of phonetic representations. Now we propose that the idea of representation of Hunminjungum be based on the delicate narrow transcription. Then we can assume that this is due to the correlation to the Chinese phonology books as well as king Sejong(世宗)'s bright ability of phonetic analysis.
