We studied learners' perceptions and learning styles of project research activities in the chemical field conducted by 54 science high school students. In a survey of students' perceptions of task research, positive responses were found in "internal motivation," "cooperation," "task solving," and "tenacity and immersion," and statistically significant differences were found in "self-directedness," "cooperation," and "tenacity and immersion" by year. The 'lower' group responded most positively in the 'cooperation' category, and the 'higher' group responded most positively in the 'task solving' category. As a result of investigating the learning styles of the students who conducted the task research, it was found in the order of assimilator, converger, accommodator, and diverger. The assimilators showed the characteristic of systematically and scientifically approaching the problem. Convergers were found to have excellent problem-solving and decision-making ability, are practical, and have experimental-based thinking characteristics. In this study, the characteristics of science high school students showed well in the results of the learning style performed.

Knowledge management system is crucial for increasing organizational performance. However, despite this importance of knowledge management system, many companies fail to facilitate individual employees' knowledge sharing. One of reasons for this failure is the lack of consideration of how individual employees' characteristics and their interpersonal relationship influence on individual-level knowledge sharing. To explain individual-level knowledge sharing, this study investigates the mechanism that employees engage in knowledge sharing activities with their coworkers from the social exchange perspective. We have two purposes of study. First, we examine whether coworker's task-related help seeking affects employee's knowledge sharing with them. Second, we investigate the influence of help-seeker' characteristics as moderators on the relationship between task-related help seeking and knowledge sharing. Specifically, we considered coworker's maladjustment, LMX, and ability as moderators. Our analysis of 192 employees shows that the main effect of coworker's task-related help seeking on knowledge sharing is not significant. However, coworker's maladjustment and LMX moderate the relationship between task-related help seeking and knowledge sharing. The positive relationship between task-related help seeking and knowledge sharing is stronger when help seeker's maladjustment is high than when it is low. And the positive relationship between task-related help seeking and knowledge sharing is weaker when help seeker's LMX is high than when LMX is low. The results of this study have theoretical implications that enrich our understanding of individual-level knowledge sharing, and managerial implications that suggest employees' appropriate attitudes to facilitate knowledge sharing in a coworker relationship.

Purpose: The purpose of this study is to clarify the role of decoupling between job characteristics, innovation behavior, and innovation resistance in order to seek ways for companies to survive and grow continuously through innovation activities in various uncertain situations. Research design, data and methodology: A total of 263 valid questionnaires were collected and used for analysis for employees working at the company. For the analysis, simple and multiple regression analysis, and 3-step mediated regression analysis were conducted using SPSS 24.0 and AMOS 24.0. Results: First, it was found that skill variety, task identity, autonomy, and feedback increase decoupling, and decoupling increases innovation resistance. In addition, it was confirmed that decoupling had a mediating effect between job characteristics and innovation resistance excluding task significance. Finally, it was found that task significance and feedback increase innovation behavior, and decoupling and task identity increase innovation resistance, but feedback can alleviate innovation resistance. Conclusions: As a result of the analysis, the fact that job characteristics excluding task importance have a positive effect on decoupling means that there are two sides of job characteristics perceived by employees. In other words, it means that the results of analysis on the jobs that the company assigns to its members may not be effective. In addition, decoupling, a phenomenon that seems to be accepting on the outside, but perceives that it is negative on the inside, means that there is a possibility to reject innovation. Therefore, prior to carrying out innovation activities, companies should give clear job specifications and meanings for the job and give them autonomy when assigning jobs to their members. In order to provide appropriate feedback, the company must design, operate, and provide feedback. It was found that there was a need to review the overall effectiveness. In addition, efforts such as strengthening corporate-level fairness, maintaining psychological contracts, and realizing authentic leadership should be preceded to reduce decoupling.

Purpose: The purpose of the present study was to examine the causal relationships among hospital nursing organizational characteristics (organizational climate, workload), individual characteristics (experience, education) and outcome variables (job satisfaction, job stress, task performance) by constructing and testing a conceptual framework. Method: Five large general hospitals located in Seoul were selected to participated. The total sample of 245 registered nurses represents a response rate of 94 percent. Data for this study was collected from January to February in 2006 by questionnaire. Path analyses with LISREL program were used to test the fit of the proposed model to the data and to examine the causal relationships among variables. Result: Both the proposed model and the modified model fit the data excellently. The model revealed relatively high explanatory power of work stress (40%), job satisfaction (46%) and task performance (27%) by predicted variables. In predicting work stress, job satisfaction and task performance, the finding of this study clearly demonstrate organizational climate might be the most important variable. Conclusion: Based on the findings of the study, it was suggested that desirable organizational climate was needed to increase the nurses' mental and physical health as well as qualified task performance.

The purpose of this study was to analyse the relationships between cognitive abilities and driving characteristics of elderly drivers. Driving characteristics of elderly and younger drivers who were driving a fixed base driving simulator vehicle were examined. Participants consisted of 12 drivers over age 65 (the 'older' group) and 12 drivers between the ages of 25 and 55 (the "younger" group). As indices of cognitive ability, critical flicker fusion frequency (CFF) tests and cognitive reaction tests were given before the driving task. CFF was also tested after the simulated driving task for both groups. Cognitive reaction tests, which were composed of speed estimation tests, multiple choice reaction tests and obstacle avoidance tests, were developed by the Korean Road Traffic Safety Authority in 2003. CFF values between the two groups exhibited significant differences both before and after the task, with a p-value less than 0.01 and a t-value of -3.01 before the test and a p-value less than 0.031 and a t-value of -2.35 after the test. Older drivers' CFF values were lower than those of the younger. However, there was no difference in older or younger driver CFF values before and after the task within the same group. Except for the multiple choice reaction test, there was no difference in cognitive reaction test results between the two groups. The elderly drivers made more errors though they did not differ from the younger drivers in reaction times. At the simulated driving task the reaction time of the elderly driver was longer than that of the younger; however, the driving speed of the elderly was lower and the number of collisions greater. There was a positive correlation (r=.496) between the number of errors in the multiple choice reaction test and the number of collisions in the driving task. Therefore, it was identified that critical attributes contributing to automobile crashes involving elderly drivers included cognitive difficulty in judging and responding to complex situations.

Purpose: The purpose of this study was to investigate the organizational citizenship behaviors(OCB) of nurses through identifying the relationship between the personal characteristics, occupational characteristics and OCB in nursing organization. Method: The subjects of this study were 223 clinical nurses. The structured questionnaires were used to collect the data. The data were analyzed using descriptive analysis, t-test, one-way ANOVA, Scheffe' test, Pearson correlation and stepwise multiple regression analysis by SPSS version 10. Results: The mean of OCB was $5.21{\pm}.59$. The OCB had statistically significant differences according to age(F=1.706, p=.007), tenure duration (F=3.450, p=.009), choice of nursing department(t=1.651, p=.000), marriage(t=2.341, p=.020) and religion(F=2.578, p=.038). The OCB was positively correlated with high-level need(r=.303, p=.000), neuroticism(r=.155, p=.020), task interdependence(r=.433, p=.000), age(r=.172, p=.010) and tenure duration(r=.190, p=.004); negatively with cynicism (r=-.310, p=.000). The task interdependence(18.7%), cynicism(7.7%) and tenure duration(1.9%) explained 28.3% of the variance for OCB in nursing organization. Conclusion: It is necessary to enhance the task interdependence, increase tenure and understand the characteristics of nurses to increase the OCB in clinical nurses.

Purpose - This study aims to empirically identify the quantitative effects of work from home (WFH) on employee productivity using field data. Design/methodology/approach - Based on large-scale field data from a South Korean company which introduced the WFH arrangement in 2020, we conducted fixed effect and moderating effect analyses using individual-level panel data over sixty-three weeks. Findings - The empirical analysis generated several findings. It was found that overall, WFH has a positive effect on productivity. However, the productivity impact of WFH was found to vary depending on task characteristics. Specifically, WFH led to over 20% increase in productivity for simple and repetitive tasks. On the other hand, no significant productivity impact was observed for professional and knowledge-based tasks. Research implications or Originality - As the first study based on field data from South Korea, this study offers convincing causal evidence of the moderating impact of task characteristics on the relationship between WFH and productivity. Further, the above findings provide managers with practical insights concerning their work arrangement decisions.
