The choice of strain, substrate, and environmental conditions are fundamental factors that determine the ability of a fungus to develop and produce mushrooms with high quality. The objective of this study was to compare the strains of Lentinula edodes and Ganoderma lucidum originated from South Korea and Brazil in relation to their vegetative development in different culture media, to obtain isolates with high quality. The strains of the two mushroom species from Brazil and South Korea grew slowly, possibly because of abiotic factors or storage technique used. However, it may be concluded that temperature, humidity, light, pH, and nutrients from the substrate, if not regulated appropriately may affect the vegetative species.

Henoch-Schönlein purpura (HSP) is the most common form of systemic vasculitis in children. Palpable purpura, arthralgia, arthritis, abdominal pain and renal involvement are the major clinical manifestations. Gastrointestinal involvement is related with abdominal pain and bleeding. We described a 71 year-old female experienced acute exacerbation of HSP presented with gastrointestinal bleeding. She was hospitalized for hematemesis and diagnosed duodenitis by esophagogastroduonenoscopy (EGD). Duodenitis was improved at EGD checked in 7 days. She still complained of melena and abdominal pain. There were no abnormal findings at sigmoidoscopy. Jejunal ulcer and purpura were diagnosed by capsule endoscopy. Symptoms were relieved after administration of systemic steroid. But she needed renal replacement therapy for 3 months. Small bowel ulcer diagnosed by capsule endoscopy in patients with HSP was rarely described in Korean literature. This case suggests that capsule endoscopy have a role in diagnosis of small bowel ulcer and its severity in HSP with gastrointestinal symptom.

( Ara Choi ),( Ju Yeun Jang ),( Ho Jung Choo ) 한국의류학회 2020 한국의류학회지 Vol.44 No.1

This study investigates the multi-dimensional structure of fashion store window creativity and examines its effects on consumer responses. Through an expert evaluation survey, this study proposes that fashion store window creativity involves originality, relevance, and artistry. Two experiments are conducted to test the proposed hypotheses. Consumers' emotional responses to the level of window creativity are collected using psychophysiological and self-report methods. Fashion store window creativity has positive effects on psychophysiological affective responses. When the three dimensions of creativity are specified as explanatory factors of emotional responses, relevance and artistry show positive effects on arousal and pleasure, whereas originality has a negative effect on pleasure. Its effect on attitudes is mediated by arousal and pleasure; in addition, the effect on entering intentions is mediated by arousal. Attitudes toward window display also have a positive effect on entering intentions. This study extends existing research on creativity in marketing into the context of visual merchandising in fashion store windows. Findings provide meaningful implications in that the effects of fashion store window creativity on emotions affect consumer attitudes and behavioral intention. By adopting multiple approaches in the empirical phase of this study, the findings are built on strong reliability and validity.

최아라(Ara Choi),조윤미(Yoon-mi Cho),류현강(Hyun-kang Ryu) 한국아동학회 2022 아동학회지 Vol.43 No.2

Objectives: This study analyzed the relationship between mothers’ emotional expressiveness, young children’s self-regulation ability, and smart device overdependence tendency. In addition, it examined the direct and indirect effects of mothers’ emotional expressiveness and young children’s self-regulation ability on the smart devices overdependence tendency through structural model analysis. Methods: Participants in this study consisted of 225 young children and their mothers living in G city. Data were analyzed using SPSS ver. 18.0 and AMOS ver. 18.0 to carry out descriptive statistics, correlation analysis, and the structural equation model. Results: The findings reveal that self-regulation ability negatively correlates with smart devices overdependence tendency. Moreover, the mother’s positive and negative emotional expressiveness indirectly affected the young children’s smart devices overdependence tendency through self-regulation. In other words, it was found that the mother’s emotional expressiveness completely mediates the young children’s self-regulation ability and indirectly affects the smart device overdependence tendency. Conclusion: The significance of this study is that it revealed risk and protective factors that affect young children’s smart device overdependence in a social situation where the problem of young children’s smart device overdependence has become more serious. Essentially, the findings can be utilized to develop a smart device overdependence prevention program for young children.
