The purpose of this study is to assess the impact of the principal's democratic leadership style, teacher competency, work discipline, and work environment on teacher performance during the pandemic. Using the proportional random sampling strategy, a sample of 468 respondents consisted of kindergarten teachers, elementary school teachers, junior high school teachers, junior high school teachers, and high school/vocational school teachers. The study revealed that the principal's democratic leadership style, teacher competence, work discipline, and work environment substantially impact teacher performance. However, the principal's democratic leadership style does not affect teacher performance, whereas teacher competence, work discipline, and work environment have a minor impact on teacher performance. Furthermore, during the COVID-19 pandemic, work discipline is the most critical variable influencing teacher performance. The findings of this study suggest that the principal's democratic leadership style, teacher competence, work discipline, and work environment have a positive impact on teacher performance during the pandemic. During the COVID-19 pandemic, work discipline is the most important variable influencing teacher performance. Considering that democratic leadership has no effect on teacher performance and that this leadership style is widely used by school principals in the world of education, it is assumed that there is no effect on teacher performance.

Purpose: The purpose of the study was to investigate the effects of infection control knowledge and nursing work environment on infection control performance among general hospital nurses. Methods: A total of 138 nurses from four general hospitals located in G and P cities participated in this descriptive study. The collected data were analyzed using t-test, ANOVA, Pearson's correlation coefficients, and multiple regression. Results: The average mean score was 21.41±1.92 points out of 25 for infection control knowledge, 2.53±0.33 points out of 4 for nursing work environment, and 4.62±0.40 points out of 5 for infection control performance. In the final analysis, the variables that had the greatest influence on infection control performance were the nursing work environment (β=.32, p<.001), working department (β=.19, p=.014), and knowledge (β=.19, p=.016). Conclusion: This study showed that nurses with a better nursing work environment, employment in general department, and more infection control knowledge delivered superior infection control performance. Therefore, to improve infection control performance, it is necessary to enhance the nursing environment and develop practical education programs for augmenting infection control knowledge.

According to the Korea Urban Air Mobility (K-UAM) Concept of Operation (ConOps), the Global Navigation Satellite System (GNSS) is recommended as the primary navigation system and the performance specification will be implemented considering the standard of Performance Based Navigation (PBN). However, by taking into account the characteristics of an urban environment and the concurrent operations of multiple UAM aircraft, the current PBN standards for civil aviation seem difficult to be directly applied to an UAM aircraft. Therefore, by referring to technical documents published in the literature, this paper examines the feasibility of applying the proposed performance requirements to K-UAM, which follows the recommendation of navigation performance requirements for K-UAM. In accordance with the UAM ConOps, the UAM aircraft is anticipated to maintain low altitude during approach and landing phases. Subsequently, the navigation performance degradation could occur in the urban environment, and the primary degradation factor is identified as multipath error. For this reason, to ensure the safety and reliability of the K-UAM aircraft, it is necessary to analyze the degree of performance degradation related to the urban environment and then propose an alternative aid to enhance the navigation performance. To this end, the aim of this paper is to model the multipath effects of the GNSS in an urban environment and to carry out the simulation studies using the real GNSS datasets. Finally, the initial navigation performance requirement is proposed based on the results of the numerical simulation for the K-UAM.

We study empirically analyzed the final 216 copies of the responses from SME organization members in Seoul and Gyeonggi regions using statistical programs of SPSS24.0 and AMOS 24.0. In other words, the effect of job satisfaction on the organizational culture and job environment characteristics perceived by members of the organization, and the relationship between job satisfaction and job performance is shown as follows. First, the organizational culture of consensus, development, hierarchy, and rationality was statistically significant in job satisfaction. Therefore, the hypothetical one-man organizational culture was adopted by showing a positive (+) effect on job satisfaction. Second, job environment characteristics such as autonomy in job performance, compensation system, physical environment, and human environment had a positive effect on job satisfaction. That is, the job environment characteristics of hypothesis 2 were adopted as a positive (+) influence relationship on organizational satisfaction. Third, job satisfaction was expressed as a positive (+) influence relationship with job performance, so hypothesis 3 was adopted. As a result of this study, the higher the organizational member's perception of organizational culture and job environment characteristics is, the higher the job satisfaction is, and the improvement in job satisfaction is meaningful in that it provides theoretical and practical implications that indicate job performance.

Purpose : The purposes of this study were to examine the relationships between knowledge, awareness, safe environment, and performance of standard precautions and identify factors associated with performance of standard precautions. Methods : This study was a descriptive research. A structured questionnaire on knowledge, awareness, safe environment, and performance of standard precautions was used for the survey with a convenience sample of 150 caregivers. Data were collected from July to August 2019 and were analyzed using descriptive statistics, independent t-test, one way ANOVA, Pearson's correlation coefficient, and multiple regression with SPSS/WIN 25.0 program. Results : The mean scores on knowledge, awareness, safe environment, and performance of standard precautions were 15.77±3.34, 7.35±1.91, 4.55±2.05, and 55.20±10.11 respectively. Performance of standard precautions showed a statistically significant positive correlation with knowledge (r=.54, p<.001), awareness (r=.54, p<.001), and safe environment (r=.50, p<.001). Awareness (β=.24, p=.025) and safe environment (β=.35, p<.001) were significantly associated with factors of performance of standard precautions. Also, education level (high school and above college), affiliated institution (private association), and importance of infection control education (moderate) were significantly associated with factors of performance of standard precautions. Conclusion : The results of the study indicate that factors influencing the performance of standard precautions of caregivers were awareness and safe environment. Therefore, to improve implementation of the standard precautions among caregivers, a safe environment within the hospital must be supported, and appropriate infection management education needs to be provided to caregivers to improve their knowledge and awareness of the standard precautions.

Recently, mobile communication systems are suffering from exponentially increasing data traffic. As a promising solution to the increase in data traffic, a coordinated multi-point transmission and reception (CoMP) scheme has been proposed. Although a great deal of research has been done on this new technology, the performance of mobile communication systems with CoMP has not been evaluated properly in a typical indoor environment. To address this, we have developed a system-level simulator and evaluated the performance of mobile communication systems with CoMP. Unlike previous works, we have used an actual antenna pattern in our simulator and link-level results are properly taken into account through link-level abstraction. By using a system-level simulator, we have evaluated the performance of mobile communication systems with CoMP in an indoor environment and found that unlike an outdoor cellular environment, CoMP may not improve the performance of overall mobile communication systems in an indoor environment.
