탄저병원균(Colletotrichum) 속의 많은 식물병원균은 한국을 비롯하여 전 세계 과수 생산에 큰 위협이 된다. 사과, 감, 자두, 복숭아, 대추, 포도 및 호두와 같은 과실에서 탄저병과 관련된 탄저병원균의 종이 동정되었다. 형태적, 다중 유전자의 계통발생적 및 병원성 시험이 다양한 접근으로 실시되었다. 동정된 탄저병원균의 종에 대한 감수성은 살균제에 대하여 평가하였다. 2종의 종복합체인 gloeosporioides와 acutatum에 속한 9종의 탄저병원균이 국내 과실에 탄저병의 주요 원인균으로 동정되었다. Colletotrichum gloeosporioides 종 복합체 안에는 6종인 C. aenigma, C. fructicola, C. gloeosporioides, C. horii, C. siamense 및 C. viniferum이 있는 반면, Colletotrichum acutatum 종 복합체 안에 종은 C. fioriniae, C. nymphaeae 및 C. orientalis이 동정되었다. 사과 탄저병원균은 C. fructicola, C. siamense, C. fioriniae 및 C. nymphaeae, 자두 탄저병원균은 C. siamense, C. fioriniae 및 C. nymphaeae, 복숭아 탄저병원균은 C. siamense, C. fructicola 및 C. fioriniae, 감 탄저병원균은 C. siamense, C. horii 및 C. nymphaeae, 오미자 탄저병원균은 C. fioriniae, 호두탄저병원균은 C. orientalis, 대추탄저병원균은 C. nymphaeae, 포도 탄저병원균인 C. aenigma, C. fructicola 및 C. siamense를 국내 과수류의 과실에 병을 일으키는 병원균의 종류로 처음 국제학술지에 보고되었다. 이들 병원균의 종에 대한 살균제의 감수성 시험에서 여러 살균제에 대한 탄저병원균의 종 간에 EC<sub>50</sub>값이 매우 다양하여 감수성의 차이가 크게 나타났다. Anthracnose, caused by the Colletotrichum genus, comprises a significant number of plant pathogens and poses a major threat to fruit production worldwide, including South Korea. Colletotrichum species were identified associated with anthracnose in fruits such as apple, persimmon, plum, peach, jujube, walnut, and grape. A polyphasic approach, including morphology, multigene phylogenetics, and pathogenicity testing, was used. Additionally, the in-vitro sensitivity of identified Colletotrichum species to common fungicides was also evaluated. A total of nine Colletotrichum species within two complexes, namely gloeosporioides and acutatum, have been identified as the causal agents of anthracnose in common fruits in South Korea. In the gloeosporioides complex, we found Colletotrichumaenigma, C. fructicola, C. gloeosporioides, C. horii, C. siamense, and C. viniferum. Meanwhile, in the acutatum complex, C. fioriniae, C. nymphaeae, and C. orientalis were identified. Notably, C. fructicola, C. siamense, C. fioriniae, and C. nymphaeae were reported for the first time from apple, C. siamense, C. fioriniae and C. nymphaeae from plum, C. siamense, C. fructicola, and C. fioriniae frompeach, C. siamense and C. horii from persimmon, C. fioriniae from Omija (Schisandra), C. orientalis from walnut, C. nymphaeae from jujube, and C. aenigma, C. fructicola, and C. siamense fromgrape. Fungicide sensitivity tests revealed significant variation in the EC<sub>50</sub> values among specific Colletotrichum species when exposed to different fungicides. Moreover, the same Colletotrichum species isolated from different host plants displayed varying sensitivity to the same fungicide.

Objective:This study was performed to analyze the clinical variables associated with occurrence of delirium tremens (DT) in inpatients with alcohol dependence initially admitted with diseases unrelated to alcohol. Methods:This study included 132 inpatients seeking treatment for medical problem with acute alcohol withdrawal. The cases were divided into two groups : with DT group (n=44), without DT group (n=88). We compared the epidemiologic data, alcohol withdrawal symptoms and serum analysis data between two groups. We used the logistic regression to predict risk factors for DT. Results:The DT group had more severe alcohol withdrawal symptoms, more amount of drinking alcohol, more number of drinking per month, higher blood urea nitrogen (BUN), creatinine, amylase, C-reactive protein and lower serum total protein than the without-DT group. According to the result of a logistic regression, occurrence of DT showed correlation with the following factors : sweating, hallucination, agitation, amount of alcohol consumption, number of drinking per month. Conclusion:Our study suggests development of DT was correlated with severe alcohol withdrawal symptoms, high BUN, creatinine and low total serum protein. Therefore, during assessment of alcohol dependent patients, clinicians should keep these parameters in mind in order to prevent DT.

Objectives:With the observation of factors influencing depression, self-reported happiness, self-reported stress and suicidal attempt, this study compared and evaluated the mental health of adolescents from multicultural families and monocultural families in Korea. Methods:This study compared the characteristics of adolescents from multicultural and monocultural families based on the analysis of data of The Tenth Korea Youth Risk Behavior Web-based Survey and analyzed the factors influencing adolescent depression, self-reported happiness, self-reported stress and suicidal attempt. Results:There was no significant difference in the levels of depression, self-reported happiness, and self-reported stress between adolescents from multicultural and monocultural families. However, suicidal ideation and suicidal attempt were significantly higher in adolescents from multicultural families. Conclusion:There was no significant difference between the mental health of adolescents from multicultural and monocultural families. Because depression is the greatest factor for suicidal attempt, and violence has stronger relationship with depression of adolescents from multicultural families, further study is needed to prevent this trend.
