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.

We have developed solar and space weather monitoring system for space weather users since 2007 as a project named 'Construction of Korea Space Weather Prediction Center'. In this presentation we will introduce space weather monitoring system for Geostationary Satellites and Polar Routes. These were developed for satisfying demands of space weather user groups. 'Space Weather Monitoring System for Geostationary Satellites' displays integrated space weather information on geostationary orbit such as magnetopause location, nowcast and forecast of space weather, cosmic ray count rate, number of meteors and x-ray solar flux. This system is developed for space weather customers who are managing satellite systems or using satellite information. In addition, this system provides space weather warning by SMS in which short message is delivered to users' cell phones when space weather parameters reach a critical value. 'Space Weather Monitoring System for Polar Routes' was developed for the commercial airline companies operating polar routes. This provides D-region and polar cap absorption map, aurora and radiation particle distribution, nowcast and forecast of space weather, proton flux, Kp index and so on.

목 적: 본 연구의 목적은 3D 안경 또는 스마트 글라스와 같은 대량생산형 안경테의 착용감을 평가하는데 있어 EEG 측정의 유용성을 보이는 것이었다. 방 법: 무작위 순서로 2 종류의 대량생산형 안경테(안경테-A와 -B)를 착용하고 있는 동안 40명의 피검자의 뇌파 강도를 주파수에 따라 측정하였다. 2 종류의 안경테에 대해서 측정된 α파의 시간에 대하여 평균 한 상대강도를 서로 비교하였다. 결 과: 안경테 A의 시간에 대하여 평균한 α파의 상대강도가 안경테 B의 시간에 대하여 평균한 α파의 상대강도보다 통계적으로 유의하게 더 강한 것으로 나타났다. 결 론: 시간에 대하여 평균한 α파의 상대강도는 대량생산형 안경테의 착용감을 상대적으로 비교하는데 있어 객관적인 지표로 활용될 수 있다. Purpose: An aim of this study was to show usefulness of EEG(electroencephalography) measurement for assessment of the wearing comfort of mass-productive eyewear frames such as 3D(three dimensional) or smart glasses. Methods: Brain wave intensities of 40 subjects were measured as a function of frequency for they wore two kinds of mass-productive eyewear frames (frame-A and –B) in random sequence. Time-averaged relative intensities of the detected α-waves were compared to each other for the two kinds of eyewear frames. Results: The time-averaged relative intensities of α-waves of the frame-A were higher than those of the frame-B with statistical significance (p < 0.05). Conclusions: The time-averaged relative intensity of α-waves can be an objective index for comparative assessment of the wearing comfort of mass-productive eyewear frames.

Background: To investigate the relationship between musculoskeletal disorders and comorbid health problems, including depression/anxiety disorder, insomnia/sleep disorder, fatigue, and injury by accident, and to determine whether certain physical and psychological factors reduce comorbid health problems. Methods: In total, 29,711 employees were selected from respondents of the Third Korean Working Conditions Survey and categorized into two groups: Musculoskeletal Complaints or Musculoskeletal Sickness Absence. Four self-reported health indicators (overall fatigue, depression/anxiety, insomnia/sleep disorder, and injury by accident) were selected as outcomes, based on their high prevalence in Korea. We used multiple logistic regression analysis to determine the relationship between comorbid health problems, musculoskeletal complaints, and sickness absence. Results: The prevalence of musculoskeletal complaints and musculoskeletal sickness absence due to muscular pain was 32.26% and 0.59%, respectively. Compared to the reference group, depression/anxiety disorder and overall fatigue were 5.2-6.1 times more prevalent in the Musculoskeletal Complaints Group and insomnia/sleep disorder and injury by accident were 7.6-11.0 times more prevalent in the Sickness Absence Group. When adjusted for individual and work-related physical factors, prevalence of all four comorbid health problems were slightly decreased in both groups. Conclusion: Increases in overall fatigue and depression/anxiety disorder were observed in the Musculoskeletal Complaints Group, while increases in insomnia/sleep disorder and injury by accident were observed in the Sickness Absence Group. For management of musculoskeletal complaints and sickness absence in the workplace, differences in health problems between employees with musculoskeletal complaints and those with sickness absence as well as the physical and psychological risk factors should be considered.

In this study, a new triplex real-time quantitative reverse transcription polymerase chain reaction (tqRT-PCR) assay was developed for the rapid and differential detection of three feline viral pathogens including feline calicivirus (FCV), feline herpesvirus 1 (FHV-1), and influenza A virus (IAV) in a single reaction. The assay specifically amplified three targeted viral genes with a detection limit of below 10 copies/reaction. The assay showed high repeatability and reproducibility, with intra- and inter-assay coefficients of variation of less than 1%. Based on the diagnostic results of the assay using 120 clinical samples obtained from cats with feline respiratory disease complex (FRDC)-suspected signs, the prevalence of FCV, FHV-1, or IAV was 43.3%, 22.5%, or 0%, respectively, indicating that the diagnostic sensitivity was comparable or superior to those of previously reported monoplex qRT-PCR/qPCR assays. The dual infection rate for FCV and FHV-1 was 8.3%. These results indicate that FCV and FHV-1 are widespread and that co-infection with FCV and FHV-1 frequently occur in the Korean cat population. The developed tqRT-PCR assay will serve as a promising tool for etiological and epidemiological studies of these three bacterial pathogens, and the prevalence data for three feline viruses obtained in this study will contribute to expanding knowledge about the epidemiology of FRDC in the current Korean cat population.

<P>Di-(2-ethylhexyl) phthalate (DEHP), one of the major phthalates, was reported to be a suspected endocrine-disrupting chemical (EDC) that might produce developmental or reproductive toxicities. Therefore, much effort was undertaken to reduce the potential risk of adverse effects of DEHP on humans by diminishing environmental exposure to this chemical. A bacterium was isolated from soil contaminated with DEHP at a poly(vinyl chloride) (PVC) manufacturing site. Biodegradation kinetic experiments on DEHP-contaminated soil samples were performed in a slurry phase system. The DEHP concentration was decreased to a concentration of 0.5 g/kg by the addition of 1% culture medium to the soil. The microorganism degraded DEHP through the formation of a mono-2-ethylhexyl phthalate (MEHP), which was subsequently metabolized to phthalic acid (PA), as detected by GC-MS analysis. Micrococcus luteus was able to degrade almost 90% of the initial DEHP within 12 d. In addition, the microbial toxicity study of DEHP and its degradation products MEHP or PA, using recombinant bioluminescent bacteria, showed that PA or the mixture produced protein or DNA damage. Data thus suggest that a new strain of Micrococcus luteus with a strong ability to degrade DEHP into nontoxic metabolites may contribute to decontamination of environmental phthalates and consequently risk reduction of human exposure to DEHP.</P>
