The purpose of this study is to investigate the memory enhancing effect and underlying molecular mechanism of arabinoxylan (AX), a major component of dietary fiber in wheat against scopolamine (SCO)-induced amnesia in Sprague-Dawley (SD) rats. Diverse behavior tests including Y-maze, Morris water maze, and passive avoidance tests were performed to measure cognitive functions. SCO significantly decreased the spontaneous alterations in Y-maze test and step-through latency in passive avoidance test, whereas increased time spent to find the hidden platform in Morris water maze test compared with the sham control group. In contrast, oral administration of AX (25 mg/kg and 50 mg/kg) effectively reversed the SCO-induced cognitive impairments in SD rats. Furthermore, AX treatment up-regulated the expression of brain-derived neurotrophic factor (BDNF) in the cortex and hippocampus via promoting activation of cAMP response element binding protein (CREB). Therefore, our findings suggest that AX can improve SCO-induced learning and memory impairment possibly through activation of CREB and up-regulation of BDNF levels, thereby exhibiting a cognition-enhancing potential.

Wireless sensor network has been widely used in Internet of Things (IoT) applications to support large and dense networks. As sensor nodes are usually tiny and provided with limited hardware resources, the existing multiple access methods, which involve high computational complexity to preserve the protocol performance, is not available under such a scenario. In this paper, we propose an intelligent Medium Access Control (MAC) protocol selection scheme based on machine learning in wireless sensor networks. We jointly consider the impact of inherent behavior and external environments to deal with the application limitation problem of the single type MAC protocol. This scheme can benefit from the combination of the competitive protocols and non-competitive protocols, and help the network nodes to select the MAC protocol that best suits the current network condition. Extensive simulation results validate our work, and it also proven that the accuracy of the proposed MAC protocol selection strategy is higher than the existing work.

This study investigates the user experience (UX) of first aid training using virtual reality (VR) technology. As VR continues to be adopted for educational and training purposes, it is important to understand how learners perceive and engage with this medium for developing critical skills, such as first aid. In this study, we developed a VR application called "VR First Aid" that includes training modules on three emergency scenarios: heatstroke, shock, and seizure. The application has both tutorial and hands-on training components. We conducted a UX study by administering a questionnaire to participants. The UX of learning through the VR application was then compared to using a traditional e-book format. Results indicate that participants perceived stronger internal behavior control with the e-book but reported better confirmation, engagement, enjoyment, and intention to use when training with the VR system. Gender differences were also explored, revealing that female participants expressed greater interest in learning through the VR platform compared to male participants. These findings provide insights into the strengths and limitations of VR-based first aid training compared to traditional methods. Implications for the design and deployment of VR training systems are discussed, with a focus on optimizing the learner experience and learning outcomes.

Public accountant profile dominated by over-50-year-old people appears to be alarming. The intention towards this profession had better be fostered immediately; therefore, the predictors to boost the intention need to be known. The study examines the influence of accounting knowledge toward the intention to work as public accountant using the Theory of Planned Behavior approach. A survey of 146 students revealed that there was a significantly positive influence of accounting knowledge toward the intention of becoming public accountant, both directly and indirectly, through the mediation of attitudes and perceived behavioral control. Subjective norms did not function as an appropriate mediation. The findings are expected to contribute to universities and professional accounting bodies. The study urges the accounting educators to redesign and reorganize the curriculum, including a more interesting teaching and learning methods. The professional accounting bodies are expected to cooperate with accounting educators in enhancing the internship program and providing real-case study to instill a positive attitude and assurance toward the students' competence, which, in the end, might spark the intention to work as public accountant. That accounting knowledge positively influences the intention toward public accounting profession through the mediation of perceived behavioral control was statistically supported.

Purpose: This study was undertaken to present an effective plan for the development of an educational program and a strategy to promote patient safety management activities for nursing students by identifying factors that affect these activities based on the theory of planned behavior. Methods: A self-report questionnaire was distributed to 300 nursing students who had clinical practice experience at three nursing colleges in Daejeon, Gyeongbuk, and Jeonbuk. The significance of the model fit, and the path effect was confirmed by confirmatory factor analysis. Results: The hypothetical model for patient safety management activities was appropriate. Among the 5 pathways, 4 were significant. It was found that behavioral intention had a direct influence on patient safety management activities, and perceived behavioral control and attitude had an influence on behavioral intention. Conclusion: To strengthen the perceived behavioral control of nursing students' patient safety management activities, it is necessary to analyze and remove obstacles and provide education that reflects the characteristics of the subject's health problems. In addition, through self-directed learning involving simulation practice, nursing students should be exposed to patient safety accidents, so that they can recognize the risks early and solve problems through critical thinking while bringing about the necessary changes in their attitude.

The view point of the library is treated as a first subject. This study is scheduled to construct, as a experimental study, the system of the Library Science. The study of this fields is called upon greatly because the trial to understand library as a socio-cultural phenomenon did not study as many times. As a result of the study, library is defined as ${\ulcorner}Structural Formation of Inquirying Behavior{\lrcorner}$. Not only technique and actual proof are possible in this study but also this definition is technical definition to indicate the main phenomenon of Librarial Behavior. This schedule represent the trial to define Library Behavior which could anticipate and fabricate when we analyze this definition First, we can find out, first of all, the researching behavior among the human behaviors and then human behavior has the condition of practice. At last, researching behavior can not have any result when it is a natural situation, it has only the meaning when it is guided by an obvious intention. The object of the library is just this human behavior. Second, Formation permits the guidance and self-control at the same-times. The answer about what we find out and practice make it possible the act of guidance. This guidance can't burden any subject but permit the people to result his own researching behaviors. He can save his activities, his own researching behaviors by the result of it. Third, The statematical means efficient performances, and them efficient performances is impossible, here is 'discoveries' of behavior itself. The system of the library is the formation of the relation between the accumulated civilizations and accumulated civilizations. As the definitions of the above mentions, library has the big abilities to the creation and succession of the civilization. As the contemporary view-points, there are some questions about the above described definition can meet it of the library. When we frame the science of library as the learning systems, we can't but the library as this definitions.

Objectives : Increasing evidence supports the biological and pharmacological activities of essential oils on the central nervous system such as pain, anxiety, attention, arousal, relaxation, sedation and learning and memory. The purpose of present work is to investigate the protective effect and molecular mechanism of cypress essential oil (CEO) against scopolamine (SCO)-induced cognitive impairments in C57BL/6 mice. Methods : A series of behavior tests such as Morris water maze, passive avoidance, and fear conditioning tests were conducted to monitor learning and memory functions. Immunoblotting and RT-PCR were also performed in the hippocampal tissue to determine the underlying mechanism of CEO. Results : SCO induced cognitive impairments as assessed by decreased step-through latency in passive avoidance test, relatively low freezing time in fear conditioning test, and increased time spent to find the hidden platform in Morris water maze test. Conversely, CEO inhalation significantly reversed the SCO-induced cognitive impairments in C57BL/6 mice comparable to control levels. To elucidate the molecular mechanisms of memory enhancing effect of CEO we have examined the expression of brain-derived neurotrophic factor (BDNF) in the hippocampus. CEO effectively elevated the protein as well as mRNA expression of BDNF via activation of cAMP response element binding protein (CREB). Conclusions : Our findings suggest that CEO inhalation effectively restored the SCO-impaired cognitive functions in C56BL/6 mice. This learning and memory enhancing effect of CEO was partly mediated by up-regulation of BDNF via activation of CREB.
