The present study was to investigated the effects of motion-based virtual reality training on cognitive function and activities of daily living in patients with stroke. This study was participated in forty one patients with acute stroke. All subjects were randomly assigned into either the experimental group(n=20) or the control group(n=21). The both groups received the conventional occupational therapy during 30 min a day, 5 a week, 4 a weeks. Additionally, experimental group performed motion-based virtual reality training on each session during 30 min/day, and control group conducted conventional occupational therapy on each session during 30 min/day. The outcome measures were the LOTCA(Loewenstein Occupational Therapy Cognitive Assessment), TMT(Trail Making Test), VM(Visual Memory), K-MBI(Korean Modified Barthel Index). In comparison of change score of cognitive function, the experimental group showed a significantly greater improvements in attention and visual working memory than the control group(p<.05). As a result for change score of activities of daily living, the experimental group showed a significant greater improvement in self care than the control group(p<.05). Our findings suggest that motion-based virtual reality training may have a effects of the improvements of cognitive function and activities of daily living than conventional therapy in patients with acute stroke.

BACKGROUND: Soybean [Glycine max (L.) Merrill] is a legume and an important oil crop worldwide. This study was conducted to evaluate the possible impact of transgenic soybean cultivation on the soil microbial community. METHODS AND RESULTS: Microorganisms were isolated from the rhizosphere soils. Microbial community was identified based on the culture-dependent and molecular biology methods. The total numbers of bacteria, fungi, and actinomycete in the rhizosphere soils cultivated with transgenic and non-transgenic soybeans were similar to each other, and there was no significant difference between transgenic and non-transgenic soybeans. Dominant bacterial phyla in the rhizosphere soils cultivated with transgenic or non-transgenic soybeans were Actinobacteria, Firmicutes, and Proteobacteria. The microbial communities in transgenic and non-transgenic soybean soils were characterized using the denaturing gradient gel electrophoresis (DGGE). The DGGE profiles showed the different patterns, but didn't show significant difference to each other at 0.05 significance level. DNAs were isolated from soils cultivating transgenic or non-transgenic soybeans and analyzed for persistence of transgenes in the soil by using PCR. PCR analysis revealed that there were no amplified ${\gamma}$-tmt and bar gene in soil DNA. CONCLUSION(S): The results of this study suggested that microbial community of soybean field were not significantly affected by cultivation of the transgenic soybeans.

The purpose of this study is to examine the relationship between the personal characteristics of Small and Medium-Sized Enterprises(SMEs) CEOs, on innovation behavior and corporate innovation performance, and to verify the mediating role of innovation behavior. To verify the hypothesis of this study, a questionnaire was conducted on 264 CEOs and 563 top managements of SMEs in Seoul and Gyeonggi-do. For the analysis of the investigated data, the research model and hypothesis were verified through correlation analysis, confirmatory factor analysis and SEM using SPSS and AMOS. The analysis results are as follows. First, it was found that extroversion, the personal characteristics of SMEs CEOs, had a positive (+) effect on innovation behavior, and second, openness to experience, the personal characteristics, also had a positive (+) effect on innovation behavior. Third, it was analyzed that the influence of innovation behavior on the innovation performance of a company had a positive (+) effect. Fourth, it was found that innovation behavior had full mediation effects in the relationship between extroversion and corporate innovation performance, but the case of openness to experience was not significant. Finally, the significance, implications, and limitations of the study were described, and suggestions for further study were presented.

The COVID-19 pandemic has highlighted the importance of firm resilience, particularly for small and medium-sized enterprises (SMEs). This study aimed to investigate the concept of SME resilience, the role of entrepreneurial orientation in enhancing firm resilience, and the impact of top management networking capability on this relationship. The study defined firm resilience as consisting of adaptation capacity and recovery capacity and conducted a survey of 187 domestic SMEs for empirical verification. The findings indicate that entrepreneurial orientation is a critical factor in enhancing firm resilience. Furthermore, the networking capability of top management may also contribute to firm resilience, but it weakens the relationship between entrepreneurial orientation and firm resilience as a moderating variable. In crisis situations, SMEs tend to rely more strongly on existing networks, rather than engaging in new network to acquire new resources, information, and knowledge, which can hinder their ability to adapt and recover. This study contributes to the further development and understanding of SME resilience, which is essential for enterprises to overcome crises and return to pre-shock levels.
