Purpose: This study aims to provide basic data to improve disaster nursing competency by identifying nursing students' disaster awareness, disaster preparedness, and disaster nursing competency and confirming the relationship among them. Research design, data, and methodology: The subjects of this study were 310 students attending the Department of Nursing at E University in Gyeonggi-do, and the data was collected from April 13 to May 24, 2023. Results: Disaster awareness averaged 72.91±7.46 points, disaster preparedness averaged 2.82±2.81 points, and disaster nursing competency averaged 44.11±10.76 points. Disaster preparedness and disaster nursing competency were significantly higher in subjects with disaster nursing education experience than in those without experience. Disaster awareness showed a significant positive correlation with disaster preparedness (r=.20, p <.001), and also with disaster nursing competency (r=.37, p <.001). Disaster preparedness showed a significant positive correlation with disaster nursing competency (r=.49, p <.001). It was found that the disaster nursing competency was high when the disaster awareness (B=0.472, p<.001), and the disaster preparedness (B=1.561, p<.001) was high. Conclusions: The results show it is possible to improve students' disaster nursing competency by strengthening education on disaster awareness and disaster preparedness. Thus, specific efforts and future research are needed to develop disaster nursing education.

Reaction characteristics and kinetics of a oxygen carrier (OCN717-R1SU) for chemical looping combustion (CLC) have been investigated using TGA by changing gas concentration (10-30 vol.% $CH_4$) and reaction temperature ($825-900^{\circ}C$). Reaction rate of OCN717-R1SU increased as temperature increased and it was found that reaction is delayed at the initial reaction regime. Johnson-Mehl-Avrami (JMA) model was adopted to explain the reaction phenomenon. The activation energy (E) determined by JMA model in reduction reaction of OCN717-R1SU is $151.7{\pm}2.03kJ/mol$ and pre-exponential factor and JMA exponent were also obtained. The parameters calculated in this study will be applied in design of the reactor and operation conditions for CLC process.

Maemi Dual Field Telescope System (MDFTS) is a dual telescope system located at Kyung Hee University. The system consists of 0.4 m telescope and 0.1 m telescope for wide-field observation. The 0.4 m telescope provides photometric observation which covers a field of view of 21'×16'. It has been used for various purposes with Johnson-Cousins UBVRI broadband filter system, e.g., SomangNet and Intensive Monitoring Survey of Nearby Galaxies. In this poster, we present the standard calibration result for our broadband filter system. Also, we suggest a new usage of the KHAO 0.4m telescope which is narrowband photometry by demonstrating the standard calibration of H-alpha filter. For flux calibration, not only R filter but also V filter is used for compensating the central wavelength discrepancy between R filter and H-alpha filter.

We analyzed the responses of 152 science-gifted high school students by surveying the status and recognition of writing and keeping laboratory notebooks to develop guidelines and education plans. Science-gifted students did not write laboratory notes diligently, despite recognizing that it is crucial to do so. Mentors also tended not to provide faithful guidance and inspection. There was an insufficient practice in using research evidence in laboratory notebooks, such as including names and dates for authentication. In addition, while a high ratio of students owned their own laboratory notebooks, there was not a high level of recognition regarding the retention period, ownership, and responsibility. Based on these results, we propose suggestions for improving educational institutions for gifted students in science. First, it is necessary to strengthen the guidance for science-gifted students to faithfully write laboratory notebooks. Second, education on writing laboratory notebooks should be provided. Third, science-gifted high schools should prepare regulations for the management of lab notes and conduct education based on them.

The History of Mathematics (HOM) was integrated in teaching the Cartesian Coordinate Plane (CCP) to Grade Seven learners of Moonwalk National High School using Lesson Study. After the lesson was taught, there were three valuable issues emerged: (1) HOM is a Springboard and/or a Medium of Motivation in Teaching CCP; (2) The History of CCP Opened a Wider Perspective about Its Real-life Application in the Modern World (3) Integration of History Developed a Sense of Purpose and an Appreciation of Mathematics Among Learners. Feedbacks solicited from the learners showed that they have understanding of the importance of studying Mathematics after they learned the life and contributions of Rene Descartes to Mathematics. Hence, integration of history plays a vital role in developing positive attitudes among learners towards Math.

The RGB Bayer filter system consists of mosaic R, G, and B filters on the grid of photo sensors with which typical commercial DSLR (Digital Single Lens Reflex) cameras and CCD/CMOS cameras are taken. Many unique astronomical data taken with RGB Bayer filter systems are available, including transient objects, e.g., supernovae, variable stars, and solar system bodies. The utilization of such data in scientific research strongly requires reliable photometry transformation methods. In this work, we develop a series of formulae to derive magnitudes in the Johnson-Cousins BVR filter system from those in the RGB Bayer filter system.

C-C chemokine receptor type 5 (CCR5) regulates the trafficking of various immune cells to sites of infection. In this study, we showed that expression of CCR5 and its ligands was rapidly increased in the kidney after systemic Candida albicans infection, and infected CCR5^-/- mice exhibited increased mortality and morbidity, indicating that CCR5 contributes to an effective defense mechanism against systemic C. albicans infection. The susceptibility of CCR5^-/- mice to C. albicans infection was due to impaired fungal clearance, which in turn resulted in exacerbated renal inflammation and damage. CCR5-mediated recruitment of NK cells to the kidney in response to C. albicans infection was necessary for the anti-microbial activity of neutrophils, the main fungicidal effector cells. Mechanistically, C. albicans induced expression of IL-23 by CD11c⁺ dendritic cells (DCs). IL-23 in turn augmented the fungicidal activity of neutrophils through GM-CSF production by NK cells. As GM-CSF potentiated production of IL-23 in response to C. albicans, a positive feedback loop formed between NK cells and DCs seemed to function as an amplification point for host defense. Taken together, our results suggest that CCR5-mediated recruitment of NK cells to the site of fungal infection is an important step that underlies innate resistance to systemic C. albicans infection.
