The purpose of this study was to investigate the knowledge and awareness about radiation use among non - radiation undergraduates. This analysis were used based on the collected questionnaires with Frequency, mean and standard deviation, t-test, one-way ANOVA. As a result, there was no significant difference between the groups in terms of gender and age. There were statistical differences in some items in the major field. In addition, the perception of radiation was more negative in women and under 25 years of age (p<0.05). The correlations between the sub - factors showed that the higher the knowledge of radiation, the higher the perception of knowledge and use of radiation. It is believed that university students will have a positive effect of contributing to the development of the radiation industry if they have a correct understanding of radiation because they are more likely to contribute to public opinion by advancing into society.

The purpose of this study was to investigate the relationship between job stress and coping style in college students. Participants were 314 students in a college. Data were collected using a self administered questionnaire. The survey was conducted from May 02, 2018 to May 28, 2018. There were statistically significant correlations between personality stress, family environmental stress, academic stress, school environment stress and emotion - centered coping style among sub - variables of job stress, Job anxiety stress was significantly correlated with social support seeking and emotion - centered coping style. Since college students' emotional stress coping style is related to depressive emotional and physical health problems, it is necessary to provide a psychological treatment program for early detection and coping with psychological support services, and a mixed service such as education, lecture, and camp. In addition, it is thought that strategic action skill training (plan, method, and technology) is needed to change from emotion - centered coping style to problem - solving style.

Altmetrics or alternative metrics gauge the digital attention received by scientific outputs from the web, which is treated as a supplement to traditional citation metrics. In this study, we performed a meta-analysis of correlations between classic citation metrics and altmetrics indicators of library and information science (LIS) articles. We followed the systematic review method to select the articles and Erasmus Rotterdam Institute of Management Guidelines for reporting the meta-analysis results. To select the articles, keyword searches were conducted on Google Scholar, Scopus, and ResearchGate during the last week of November 2021. Eleven articles were assessed, and eight were subjected to meta-analysis following the inclusion and exclusion criteria. The findings reported negative and positive associations between citations and altmetric indicators among the selected articles, with varying correlation coefficient values from -.189 to 0.93. The result of the meta-analysis reported a pooled correlation coefficient of 0.47 (95% confidence interval, 0.339 to 0.586) for the articles. Sub-group analysis based on the citation source revealed that articles indexed on the Web of Science showed a higher pooled correlation coefficient (0.41) than articles indexed in Google Scholar (0.30). The study concluded that the pooled correlation between citation metrics with altmetric indicators was positive, ranging from low to moderate. The result of the study gives more insights to the scientometrics community to propose and use altmetric indicators as a proxy for traditional citation indicators for quick research impact evaluation of LIS articles.

In light of the need for a tool to evaluate the clinical practice education environment as perceived by medical and nursing students, this study is was conducted to develop and validate the Korean version of the Undergraduate Clinical Education Environment Measure (K-UCEEM) as a measurement tool for managing the clinical practice education climate and quality of education. For validation, the UCEEM consisting of 25 items developed by Pia Strand in 2013 was adapted according to standard translation procedures. The K-UCEEM questionnaire was administered to 73 medical students and 135 nursing students who participated in clinical practice at one medical institution. Exploratory factor analysis and confirmatory factor analysis were conducted to confirm the validity of the instrument's structure. In order to determine referential validity, the relationships among stresses in clinical practice were examined, and differences in factor scores were compared by gender and college. It was confirmed that the scale of 24 items and five factors showed a moderate model fitness index. The reliability of the factors ranged from 0.786 to 0.867. In addition, all five factors were found to have negative correlations with the clinical practice stress sub-factor, and there were statistically significant differences by gender and college. Through this study, the validity and reliability of the K-UCEEM were verified. In the future, it is expected that further verification of the scale, as well as evaluation and improvement of the clinical practice education environment based on this scale, will occur.

Purpose : This study aimed to identify the job satisfaction, organizational commitment, and turnover intention of workers at dementia care centers, and the correlations between these factors. Methods : A survey of 131 dementia care center employees was conducted. This comprised 48 questions covering respondent characteristics, organizational satisfaction, organizational commitment, and turnover intention. Results : Employees with no intention to change jobs had significantly higher job satisfaction and organizational commitment than those with job change intentions. Turnover intention was significantly correlated with both job satisfaction and organizational commitment. The higher the organizational commitment and the lower the turnover intention, the higher the job satisfaction. The higher the job satisfaction and the lower the turnover intention, the higher the organizational commitment. Analysis of the sub-components of the main variables found The lower the work environment, compensation, and sense of belonging to the organization, the higher the turnover intention. Conclusion : Regular educational programs are needed to improve the expertise of workers at the dementia care center, and opportunities for employees to communicate their needs should be maximized. In addition, higher salaries will attract more able and willing employees, reduce turnover, and provide and a sense of of belonging to the organization. Attention to the proper distribution of work and recruitment of appropriate human resources will further improve the working environment. If the job satisfaction and organizational commitment of workers at the dementia care center are increased and the number of employees intending to change jobs is reduced, the length of employee service will increase and contribute to improved care and service quality for dementia patients.

Purpose: The purpose of this study was to measure the relationship among activities of daily living, ego integrity, social support and the compliance of patient-role behavior in elderly patients receiving hemodialysis, including the effect of these variables on the compliance of patient-role behavior. Methods: A descriptive survey was conducted with 150 elderly patients over 65 years of age who were also receiving hemodialysis. Data was collected from September 28 to November 13, 2021 and analyzed using t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression analysis with SPSS/WIN 26.0. Results: The results show that patient compliance had significant correlations with ego integrity (r=.63, p<.001) and social support (r=.28, p=.001). The other factors influencing patient compliance were the sub-domains of ego integrity, such as the acceptance of the past and the presence (β=.46, p<.001) and attitudes toward life (β=.26 p<.001), with an explanatory power of approximately 35.0% (F=17.21, p<.001). Conclusion: This study confirms that the ego integrity of elderly patients receiving hemodialysis has an effect on the compliance of patient role behavior. Nursing intervention programs that improve the ego integrity of elderly hemodialysis patients could help improve the compliance of patient-role behavior, which is an important factor in the disease management process.

Objectives: This study aimed to explore ways to improve the level of positive psychological capital of dental hygiene students. After comparing the levels of positive psychological capital, social support, and emotional regulation ability of dental hygiene students and identifying correlations, the sub-factors of social support and emotional regulation ability that affect positive psychological capital were identified. Methods: A survey of 70 questions was conducted targeting 310 dental hygiene students in Gyeonggi-do and Chungcheong-do. The results were subjected to exploratory factor analysis, frequency analysis, t-test, one-way ANOVA, correlation analysis, and multiple regression analysis using the PASW statistics 18.0 program. Results: The level of positive psychological capital was high when students had high grades and perceived positive relationships with professors and peers (p<0.001). Factors highly correlated with positive psychological capital include 'self-emotional regulation ability' among 'emotion regulation abilities' (r=0.665, p<0.001), and 'emotional support related to daily life' recognized 'social support' (r=0.635, p<0.001), followed by 'social support' (r=0.602, p<0.001). Factors affecting positive psychological capital include 'self-emotion recognized ability' (β=0.377, p<0.001), 'quality of professor relationship' (β=0.201, p<0.001), and 'emotion control ability'. Among 'social support', 'emotional support related to daily life' (β=0.201, p=0.003) and 'grades' (β=0.159, p<0.001), and among 'social support', 'social-related support' (β=0.149, p=0.016), followed by 'grade' (β=0.076, p=0.043) were identified. Conclusions: To improve the positive psychological capital of dental hygiene students, efforts should be made to improve self-emotion regulation ability, professor relationships, emotional support related to daily life, and social support.

Drone-mounted hyperspectral sensors (DHSs) have revolutionized remote sensing in agriculture by offering a cost-effective and flexible platform for high-resolution spectral data acquisition. Their ability to capture data at low altitudes minimizes atmospheric interference, enhancing their utility in agricultural monitoring and management. This study focused on addressing the challenges of radiometric and geometric distortions in preprocessing drone-acquired hyperspectral data. Radiometric correction, using the empirical line method (ELM) and spectral reference panels, effectively removed sensor noise and variations in solar irradiance, resulting in accurate surface reflectance values. Notably, the ELM correction improved reflectance for measured reference panels by 5-55%, resulting in a more uniform spectral profile across wavelengths, further validated by high correlations (0.97-0.99), despite minor deviations observed at specific wavelengths for some reflectors. Geometric correction, utilizing a rubber sheet transformation with ground control points, successfully rectified distortions caused by sensor orientation and flight path variations, ensuring accurate spatial representation within the image. The effectiveness of geometric correction was assessed using root mean square error(RMSE) analysis, revealing minimal errors in both east-west(0.00 to 0.081 m) and north-south directions(0.00 to 0.076 m).The overall position RMSE of 0.031 meters across 100 points demonstrates high geometric accuracy, exceeding industry standards. Additionally, image mosaicking was performed to create a comprehensive representation of the study area. These results demonstrate the effectiveness of the applied preprocessing techniques and highlight the potential of DHSs for precise crop health monitoring and management in smart agriculture. However, further research is needed to address challenges related to data dimensionality, sensor calibration, and reference data availability, as well as exploring alternative correction methods and evaluating their performance in diverse environmental conditions to enhance the robustness and applicability of hyperspectral data processing in agriculture.
