Several species belonging to the Gibberella fujikuroi species (Gf ) complex are commonly associated with rice and corn, not only causing serious diseases, but also producing fumonisins, a group of mycotoxins harmful to animals and humans. To characterize the population structure of the putative fumonisin-producing Gf complex in Korea, we obtained 276 candidate isolates from rice and corn harvested in 2009 and 2010 by diagnostic polymerase chain reaction with several specific primer sets. Phylogenetic trees were constructed using multilocus sequences (combined RPB2 and EF1A, totaling 1.6 kb) from these isolates. Among the 135 isolates from rice, F. fujikuroi (teleomorph: G. fujikuroi; 59.3%) and F. proliferatum (G. intermedia; 13.3%) were predominant, followed by F. concentricum (5.9%). Additionally, twenty-five (18.5%) rice isolates belonged in a distinct subclade of F. commune, a non-member of the Gf complex. In contrast, F. verticillioides was the most predominant species (38.3%) among the 141 corn isolates, and followed by F. fujikuroi (27.7%), F. proliferatum (14.9%), F. subglutinans (7.1%), and F. concentricum (2.8%). A single mating type (MAT1-1) was found predominantly among the Gf complex isolates examined. Possible distinct subclades were detected within the populations of F. fujikuroi and F. proliferatum; however, this needs further confirmation. This is the first reported population-level characterization of putative fumonisin-producing Gf complex associated with rice and corn in Korea.

Many studies have reported that retinal defocus cause and increase refractive error specially myopia. Uncorrected astigmatism may be one factor of retinal defocus factors. To understand the relationship between myopia and astigmatism 62 college students were participated in this study. Spherical refractive error and astigmatism were measured using N-vision 5001 autorefractor (Shinnippon). Co-relations between spherical refractive error and astigmatism were high both in the with-the-rule astigmatism group(r=0.53; ANOVA F=32.40, N=87, P<0.05) and oblique astigmatism group (r=0.53ANOVA F=5.14, N=15, P<0.001). However it was very low (r=0.09; ANOVA F=0.18, N=22, P<0.001)in the against-the-rule stigmatism group. In the total group co-relation was also high (r=0.56: ANOVA F=77.80, N=173, P<0.001). Uncorrected astigmatism may cause and increase spherical refractive error.

Purpose: This study was carried out to suggest methods for improving school health promotion programs by investigating the daily activities and the performance level of environment management, the awareness of importance, and opinions on the revision of and knowledge about laws and regulations related to school health promotion programs. Method: The subjects of this study were 289 school nurses in Gyeongsangbuk-do. The survey used a questionnaire containing 90 questions developed by the present researcher. Data were collected from July 5 to July 21, 2006 and analyzed using SPSS 12.0 for Windows. Result: 1. Regular check-up and drinking water management got the highest score in performance level. Sexual health and drinking water management got the highest score in the awareness of importance. 2. School nurses were aware of laws and regulations related to their clients (0.93), and the revision opinion was high on the whole (3.58). 3. According to general characteristics, the more educated school nurse were (F=6.80, p=.001) and the fewer students their school had (F=4.66, p=.010), the higher their performance level in daily activities was. The shorter their career in their work was (F=4.86, p=.008), the fewer classes their school had (F=5.04, p=.007) and the fewer students their school had (F=3.83, p=.023), the higher their awareness of importance was. 4. There was not any difference in the performance level of environment management according to general characteristics. The awareness of importance was highest in school nurses with experience less then ten years (F=3.66, p=.027). 5. There was not any difference in knowledge about laws and regulations according to general characteristics. The revision opinion was high in school nurses at schools with less than 18 classrooms (F=6.04, p=.003) and less than 500 students (F=4.24, p=.015). Conclusion: When school nurses perform school health promotion programs actively and vigorously, the students can be healthy and national health promotion can be actualized fundamentally.

A 52-year-old woman with a history of general weakness, fatigue, weight loss, elevated serum levels of liver transaminase enzyme for three months underwent an F-18 FDG PET/CT scan to evaluate a cause of the hepatosplenomegaly found on abdominal ultrasonography. Initial PET/CT revealed markedly enlarged liver and spleen with intense FDG uptake. Otherwise, there were no areas of abnormal FDG uptake in whole body image. Histological evaluation by a hepatic needle biopsy demonstrated diffuse large B cell type lymphoma and final diagnosis for this patient was hepatosplenic B-cell lymphoma. She received five cycles of CHOP chemotherapy, and second PET/CT scan was followed after then. Follow-up PET-CT revealed normal sized liver with disappearance of abnormal FDG uptake. Hepatosplenic B-cell lymphoma is relatively rare and mostly presents as single or multiple nodules.1,2 Diffuse type hepatosplenic lymphoma is extremely rare and poorly recognized entity.3 The diagnosis is very difficult and complicated by the presence of misleading symptoms.4 In this rare hepatosplenic B-cell lymphoma case, F-18 FDG PET/CT scan provided a initial diagnostic clue of hepatosplenic lymphoma and an accurate chemotherapy response.

This study was conducted to investigate the factors influencing perceived father communication, emotional expressiveness and gender identity on self-efficacy of female nursing college students. Data were collected from 270 female nursing students in B city, from May 23, 2016 to May 27 and then analyzed by ANOVA, Pearson's correlation coefficient, and multiple regression using SPSS/WIN 21.0. The degree of self-efficacy among female nursing students was $3.21{\pm}0.38$. There were significant differences in self-efficacy with respect to academic status(F=5.13, p=.006), relationship with father(F=4.74, p=.001), academic grade(F=5.22, p=.006), and gender satisfaction (F=4.00, p=.004). There were positive correlations between self-efficacy and open communication(r=.30, p<.001), self-efficacy and positive emotional expressiveness(r=.37, p<.001), and self-efficacy and gender identity(r=.26, p<.001), while there were negative correlations between self-efficacy and close communication(r=-22, p<.001), and self-efficacy and negative emotional expressiveness(r=-.26, p<.001). Regression analysis showed 18.2% variance in female nursing student's self-efficacy in response to positive emotional expressiveness, negative emotional expressiveness, and gender identity. Overall, the results of this study indicate that it is necessary to identify various factors affecting and increasing self-efficacy of female nursing college students.

We report on white organic light-emitting diodes (WOLEDs) based on single white dopants, $Ir(pq)_2$($F_2$-ppy) and $Ir(F_2-ppy)_2$(pq), where $F_2$-ppy and pq are 2-(2,4-difluorophenyl) pyridine and 2-phenylquinoline, respectively. The similar phosphorescent lifetime of two ligands lead to luminescence emission in two ligands simultaneously. However, the emission color of the devices was reddish, because the energy was not transferred efficiently from the 4,4,N,N'-dicarbazolebiphenyl (CBP) to the $F_2$-ppy ligand, due to the small band gap of the CBP. Accordingly, we used 1,4-phenylenesis(triphenylsilane) (UGH2) with a large band gap, instead of CBP as the host material. As a result, it was possible to adjust the emission color by the host material. The luminous efficiency of the device with $Ir(F_2-ppy)_2$(pq) doped in UGH2 was about 11 cd/A at 0.06 cd/$m^2$.

Benign metastasizing leiomyoma(BML) is a rare condition affecting women with a history of having undergone hysterectomy or myomectomy for a benign uterine fibroid, that is found to have metastasized to extrauterine sites, usually many years after hysterectomy. 1,2) Patient with BML almost always asymptomatic, although if the lesions are large enough, they can cause compressive symptoms. Among several hypothesis of pathogenesis, most plausible theory is that these tumors represent a true metastatic lesion but are very low-grade sarcoma. 3) Because the tumor is responsive to estrogen, menopause and pregnancy have slowed the growth of these lesion 4) and it seems reasonable to perform hysterectomy in patients with a uterine mass and, at the same time, perform oophorectomy for hormonal control. BML is an unusual cause of diffuse pulmonary nodules which should be considered in females with unexplained nodules and a history of surgery for uterine leiomyoma.
