The purpose of this study was to investigate factors associated with the critical thinking ability of nursing students at the individual and school levels. The study adopted a descriptive design and recruited 465 nursing students from four nursing schools from November 2014 to September 2015 through convenience sampling. The Clinical Critical Thinking Skill Test was used to measure critical thinking ability, and the data were analyzed with the SAS ver. 9.4 program (SAS Institute Inc., Cary, NC, USA) for descriptive statistics, t-test, analysis of variance, and multi-level model. The results showed that clinical practicum experience (${\beta}=-0.72$, p=0.025), taking critical thinking courses (${\beta}=0.63$, p=0.010), and taking simulation courses (${\beta}=0.56$, p=0.035) improved critical thinking ability in the individual level model. In the school level model, the interaction effect between the years of clinical practice done by the student and the presence of full-time clinical instructors was significant (${\beta}=1.29$, p=0.011). These results suggest that critical thinking ability improves with the more years of clinical practice individual nursing students have, and this improvement is greater with the presence of full-time clinical instructors in the school. Therefore, it is recommended that nursing students undergo critical thinking and simulation courses to develop their critical thinking ability, and dedicated clinical instructors in nursing schools should play a vital role.

Background: Lead (Pb) exposure in shooting ranges has been reduced by various measures such as jacketed ammunition and lead-free primers. Nevertheless, this may lead to exposure to other metals, potentially resulting in adverse health effects. Methods: In a cross-sectional study, 35 subjects from seven different shooting ranges were studied: four shooting instructors, 10 police officers, 15 Special Forces, and six maintenance staff members. Metals and metalloids were determined in blood and urine by inductively coupled plasma-mass spectrometry. Results: The concentrations of most elements did not differ significantly between groups or compared to reference values, except for Sb and Pt in urine and Pb in blood. Mean values for Sb were considerably higher in urine from the Special Forces ($0.34{\mu}g/L$), the maintenance staff ($0.13{\mu}g/L$), and shooting instructors ($0.32{\mu}g/L$) compared to the police officers before shooting ($0.06{\mu}g/L$) and a Belgian reference value ($0.04{\mu}g/L$). For Pt, the Special Forces showed higher mean urinary concentrations ($0.078{\mu}g/L$) compared to a Belgian reference value (<$0.061{\mu}g/L$). Mean values for blood lead were markedly higher in the Special Forces ($3.9{\mu}g/dL$), maintenance staff ($5.7{\mu}g/dL$), and instructors ($11.7{\mu}g/dL$) compared to police officers ($1.4{\mu}g/dL$). One instructor exceeded the biological exposure index for blood Pb ($38.8{\mu}g/dL$). Conclusion: Since both Pb and Sb were found to be higher in shooting range employees, especially among frequent shooters, it is advisable to provide appropriate protective equipment, education, and medical follow-up for shooting range personnel in addition to careful choice of ammunition.

This study aimed to understand and analyze the learners' class satisfaction and the effectiveness of synchronous online classes after COVID-19. A total of 188 learners participated in the survey conducted at the end of the Fall Semester 2020 at C University located Gyeongsangnam-do. Findings revealed that learners' satisfaction with the synchronous online classes was relatively low, and the learners had negative perception of that. Learning content have the biggest effect on the learners' class satisfaction. Next came class management and the online learning platform. Therefore, instructors need to organize learning content effectively and enhance learners' understanding considering the most influential variable, learning content so that learners are satisfied with the synchronous online classes. Also, instructors should make it possible for learners to get familiar with the online learning platform and use it without any problems through systematic and faithful class design for effective learning in unfamiliar online learning environment. In addition, instructors need to know learners' needs and difficulties and plan their synchronous online classes. This study has limitations in that it was conducted only at one college and the limited number of variables was measured.

We tested the difference and the relationship in instructional ratings by professors and college students. Subjects were 6 professors and 9 college students participated in teaching competition as a rater. They completed instructional rating forms consisted of 10 criteria for 11 participants according to Lickert Scale. Data were analyzed by independent t-test and Pearson correlation. Results were as follows: ① There was no statistical difference in mean scores between the professor and the student; ② Correlation between professors' and students' evaluations was .78 which is statistically meaningful and high. These results support the notion that students evaluate as reliably as professors. They also imply that pre-service college students can be utilized for teaching practice as meaningful peer evaluators. The findings are meaningful in that instructional ratings of instructors and students were compared in a controlled setting. However, replication studies involving wide range of instructors and students are needed for generalization since the subjects in this study were restricted to pre-service teachers and their instructors.

Purpose: It is intended to investigate the satisfaction of dental hygiene students with non-face-to-face online classes and use them as basic data for successful lecture design and operation. Methods: The data collected in this study were analyzed using the lBM SPSS Statistics 21 program. The general characteristics of the study subjects were frequency analysis, non-face-to-face online class satisfaction, and test satisfaction were frequency analysis and technical statistics. Through the independent sample T test, a t-test was conducted to find out whether there was an average difference in online class and test satisfaction according to grade. Results: The advantages of non-face-to-face online classes were that repetitive learning was possible (57.7%), the disadvantage was that there was a lack of real-time communication (74.9%), and the most efficient teaching method was a mixed form of online and face-to-face classes (64.9%). The satisfaction level of online classes was 2.69 points for 'self-directed learning habits,' which was the highest compared to the overall average of 2.55 points, and 2.09 points for 'difficulty in interaction between instructors and learners in online classes.'Non-face-to-face test satisfaction was 2.68 points for 'short test time gives fairness to test results,' higher than the overall average of 2.45 points, and 2.07 points for 'no difficulty accessing the test.'In terms of satisfaction with the non-face-to-face test according to the grade, it was found that the third grade showed a more negative attitude than the second grade in terms of sexual fairness (p<0.05). Conclusions: Through the above results, non-face-to-face online classes require various content development and some mixed classes considering the level of students, and instructors' efforts to improve the quality of classes for interaction between instructors and learners are needed.
