In the Chinese workplace, the use of SNS such as Wechat and QQ for work delivery out of duty hours has become a very common phenomenon, which is also known as the "new night shift". This study is to empirically analyze the effect of work delivery using SNS out of duty hours on job performance. A questionnaire survey was conducted with 310 Chinese workplace employees. In order to verify the hypothesis, structural equation model analysis will be implemented. Analyzing the questionnaire data and receiving frequent work delivery using SNS out of duty hours will increase job stress, aggravate the conflicts between work and family, and lead to the decrease of job engagement and job performance. The study provides implications for the establishment of related theories by providing a different view form previous research results that work delivery using SNS out of duty hours will definitely improve job performance. In addition, in future studies, it will be necessary to analyze the effect of the moderating effect in converging these conflicting views.

Purpose: The purpose of this study was to describe the job performance, importance, and difficulty in Surgical Clinical Practice Nurses (SCPNs), and to identify the priority of job tasks using Importance-Performance Analysis (IPA). Methods: One hundred SCPNs were recruited from two university hospitals and two general hospitals during November 2021 to April 2022. A total of 97 data were analyzed excluding 3 data due to missing responses. The data were analyzed by two groups, with Ward-Based SCPNs (W-SCPNs) and Operation Room-Based SCPNs (OR-SCPNs) according to different characteristics of job tasks. Results: There were differences of job performance between W-SCPNs and OR-SCPNs. As a result of the IPA, tasks of 'working practices in the ward' for W-SCPNs and those of 'surgery and treatments' for OR-SCPNs were included in the first quadrant (keep up the good work). 'Resarch' and 'leardership' were included in the third quadrant (low priority). Conclusion: Since there are differences in job tasks between W-SCPNs and OR-SCPNs, health care institutions should consider the differences in defining the scope of job performance. Furthermore, it is necessary to develop customized continuing education program based on our findings of IPA.

Purpose: The purpose of this study was to investigate the degree of performance of TB control manpower in Korea and to identify the affecting factors associated with it. Methods: This study employed a quantitative observational with cross-sectional design and the subjects were consisted of 189 TB (Tuberculosis) control manpower who were working in both community health centers and private hospitals. Variables included in this study were demographic, social, work-related characteristics, aqhnd self-efficacy. A reliability of the instrument for the performance was Cronbach's ${\alpha}$=.91. Data were analyzed by t-test, ANOVA and multiple regression using SPSS (19th version). Results: The mean value of the degree of work-related performance of TB control manpower was $4.4{\pm}0.49$9 and it was higher than those of general nurses working in any other health care departments. The mean differences in the degree of work-related performance were in self-efficacy, workplace, the number of full charge manpower in TB, the number of participation in in-depth education, and the willingness to job maintenance. In multiple regression analysis, factors associated with TB control manpower' work-related performance were self-efficacy (${\beta}$=.164, p=.025), workplace (${\beta}$=-.186, p=.023), the number of participation in in-depth education(${\beta}$=.339, p<.002), and the willingness to job maintenance (${\beta}$=-.157, p=.036). Conclusion: Results of this study showed that work-related performances of manpower working in private hospital were higher than those of manpower in public health centers. So, it is necessary to enhance nation's active intervention to improve effectiveness and reduction of risk factors in TB policy.

Since Campbell (1990) proposed multidimensionality of job performance, unlike the single structure of traditional job performance, it has been largely classified as task performance, contextual performance, and counterproductive work behavior. The objective of this study is to validate the threecriteria currently considered major aspects of job performance, to identify different types of performance based on three dimensions, and to compare the power of personality factors among performance types. A total of 681 employees working at various organizations participated in an on-line survey. The survey included boththe exploratory and confirmatory factor analyses. A 3-factor job performance model consisting of three dimensions was also included. The relationships between performance dimensions and personality factors differedby dimensions of performance, supporting the validity of the 3-factor structure of performance.The results of the Latent Profile Analysis identified four types of performance: exemplary, moderately conscientious moderate, and conscientious, butlow.. The Multinomial logistic regression analysis showed each type differed significantly according to the predictors of personality variables. In conclusion, implications and limitations of the study were noted.

Collaborative learning encourages the use of high-level cognitive strategies, critical thinking, and interpersonal relationships. Despite these advantages, most instructors reveal the difficulties of using project-based collaborative learning; a common problem is the failure of the group to work effectively together. Thus, this study attempted to provide practical advice on group composition with self-regulation. In a college course, 31 groups with 129 students were asked to discuss and prepare the final presentation material and present it together as a collaborative work. All students' self-regulation skills were measured at the beginning of the semester, and the collective self-regulation was computed as an average of the individual scores of each group. The results of regression analysis indicate that the group's collective self-regulation shows a highly significant positive effect on group performance and satisfaction, as self-regulation predicts individual academic performance. The results also show that there is a significant positive relationship between students' self-regulation and participation in group work.

The purpose of this study was to improve work performance conducted at an actual clinical site by determining the relationship among critical thinking disposition, problem solving ability, and work performance. In this study, 335 dental hygienists completed self-administered survey. Final analysis was conducted with a total of 331 responses, excluding 4 questionnaire with unreliable responses and non-responses. The results indicated that as the age, educational background, and work experience of the subjects increased, their critical thinking disposition and problem solving ability scores increased and were statistically significant. For work performance, average total score was high for age, educational background and work experience, but only age and work experience were statistically significant. Critical thinking disposition, problem solving ability and work performance of the subject were relevant, and all of them were significant. Work performance was also influenced indirectly by mediating problem solving ability in critical thinking disposition. In other words, both direct and indirect effects were significant, and the existence of partial moderating effect was verified. Thus, in order to improve work performance of dental hygienists, a multilevel educational process that can simultaneously improve critical thinking disposition and problem solving ability of dental hygienists needs to be developed. Therefore, it is expected that the new dental hygiene company will be able to perform without any sense of disparity in the clinical field; this will solve the gap between dental hygiene education and practical skills.
