Employees' knowledge contribution is one of the critical activities that maximize internal capability of the firm and facilitate organizational innovation by sharing scattered internal knowledge. This study integrates antecedents of knowledge contribution based on the theory of planned behavior(TPB). Utilizing TPB as a theoretical framework, expected reciprocity, subjective norm, and self-efficacy's direct effects on knowledge contribution were assessed. Additionally, interaction effects among expected reciprocity, subjective norm, and self-efficacy were explored. As the results of analysis, all the antecedents significantly influenced knowledge contribution. Interestingly, when the knowledge source's self-efficacy was high, the influence of expected reciprocity on knowledge contribution was decreased. Similarly, when the knowledge source's subjective norm for knowledge contribution was high, expected reciprocity's effect was weakened. This implies that when facilitating knowledge contribution, interaction effects among antecedents of knowledge contribution, as well as their direct effects, should be considered.

Objectives : Through this study, it would be confirmed that specific expression for efficacy of medicinal material has multiple meanings. And through the methodology to determine the multi meaning, it could be contributed to lighten ambiguous expressions for efficacy of medicinal material.Methods : The premise is that the efficacy and treatment target data are related to each other. Word cloud has been used analyzing the efficacy and treatment target data for medicinal materials. Then classic and modern documents were analyzed by the search.Results : Even though searching all related references as well as comparing the efficacy and treatment target data were done, some medicinal materials having 'Salchung[殺蟲]' as an efficacy are not expected to treat the disease associated with the parasite. Through the analysis of classic and modern documents, it was found that 'Salchung[殺蟲]' is not used only as a means of anthelmintic efficacy. But through the above analysis method some medicinal materials having 'Guchung[驅蟲]' as an efficacy are expected to treat the disease associated with the parasite, and 'Guchung[驅蟲]' seems to be almost used as a means of anthelmintic efficacy.Conclusions : If a certain expression for efficacy of medicinal material is used as a single meaning obviously, ambiguous expressions need to be clear. And if a certain expression for efficacy of medicinal material seems to have multiple meanings, the additional informations are to be supplemented for exact wording.

Purpose: The COVID-19 pandemic has increased the importance of nurses' clinical performance, and accordingly, nursing educators have emphasized students' clinical practice and performance. This study developed a Clinical Practice Self-Efficacy Scale for nursing students and examined its psychometric properties. Methods: The authors reviewed instruments for selecting items for the scale in the areas of clinical skills, communication, infection control, safety, and nursing process. After preliminary items were selected, ten experts consisting of nursing professors and clinical nurses reviewed the items considering Korean clinical and educational situations. The data for the psychometric evaluation was collected from 257 nursing students in their 2nd, 3rd, and 4th years and then analyzed. Results: The confirmatory factor analysis showed that the goodness of fit of this scale with five factors represented by 40 items was appropriate. The significant positive correlations with general self-efficacy indicated sound construct validity. The senior nursing students showed higher scores than others, as we expected. Cronbach's alpha was .94. Conclusion: The Clinical Practice Self-Efficacy Scale is appropriate for measuring Korean nursing students' self-efficacy of clinical practice. It is expected to act as a good tool to measure the effects of clinical practice education.

The purpose of this study was to test the hypothetical model designed to explain nursing students' perceived stress, coping levels, and stress outcomes. This hypothetical model was based on the Kim. Jung Hee(l987)' s stress model and stress-related literature. Exogenous variables were self-efficacy. hardiness. social support. and exercise. Endogenous variables were stress perception. coping levels. and stress outcomes. Empirical data for testing the hypothetical model consisted of 205 nursing students. SAS PC Program and LISREL 8.12a program were used for descriptive statistics and linear structural relationship(LISREL) modeling. The results were as follows. 1) The overall fit of the hypothetical model to the data was good( $x^2$=78.41(p=0.010), $x^2$/ df=1.50. RMSEA=0.05, standardized RMR= 0.05, GFI=0.95, AGFI=0.91, NNFI=0.90, NFI=0.94). 2) The results of statistical testing of the hypotheses were as follows. (1) As expected. self-efficacy had a significant effect on stress perception. But. hardiness. social support, and exercise did not have a significant effect on stress perception. Self-efficacy, hardiness. social support, and exercise explained 12% of the total variance of stress perception. (2) As expected, self-efficacy, hardiness, social support, exercise, and stress perception had a significant effect on coping behavior, Self-efficacy, hardiness, social support, exercise, and stress perception explained 53% of the total variance of coping behavior. (3) As expected, stress perception and coping behavior had a significant effect on stress outcomes. Stress perception and coping behavior explained 84% of the total variance of stress outcomes. In conclusion, the hypothetical model of this study was confirmed in explaining and predicting stress perception, coping levels, and stress outcomes in nursing students. And these findings suggest the need to develop nursing intervention to enhance self-efficacy, hardiness, social support, and exercise to decrease the harmful outcomes of stress.

Purpose : The purpose of this study was to examine the effects of applying occupational therapy that uses motion recognition on the physical self-efficacy, visual-motor integration ability, and play skills of children who have neurodevelopmental disorder before and after treatment. Methods : This The study chose 16 children with neurodevelopmental disorder as research subjects who were randomly and evenly allocated into an experimental group and a control group. The experiment followed a pretest-posttest design. As an intervention, the experimental group received motion recognition-based occupational therapy and a separate sensory integration program. The control group only participated in the separate sensory integration program. The eight-week experiment duration included 24 intervention sessions where the a 50-minute session was implemented three times a week for eight weeks. To compare the physical self-efficacy, visual-motor integration ability, and play skills before and after the intervention, measurement tools including the Physical self efficacy, Beery VMI-6, and Penn interactive peer play scale were used. All measured variables were analyzed and expressed as mean, standard deviation and percentage. Results : The motion recognition-based occupational therapy demonstrated a significant effect on improving the physical self-efficacy, visual-motor integration ability, and play skills of the experimental group. The intervention also caused a significant difference between the experimental group and control group in terms of the physical self-efficacy, visual-motor integration ability, and play skills. Conclusion : We confirmed the possibility motion recognition-based occupational therapy could be effective in improving the physical self-efficacy, visual-motor integration ability, and play skills for patients who have neurodevelopmental disorder. Based on the study result, further future studies are expected based on this study result that prove the application effect of the motion recognition-based occupational therapy using disabled and non- disabled children as subjects are expected in the future.

Self-efficacy is a major factor related to performance and needs to be improved in business and education field. This study explains the effectiveness of school career assistance to improve college students' self-efficacy. Furthermore, it demonstrates the moderating effects of grit and regulatory focus (promote and prevention). School career assistance is based on group support, and moderating variables in this paper are individual characteristics. In these group and individual dimensions, if the effectiveness of school career assistance varies depending on individual characteristics, schools will be able to establish self-efficacy improvement strategies more appropriate for individual students. School would understand individual characteristics such as grit and regulatory focus, then could make individual strategy for enhancing self-efficacy and performance. Hence, it is expected that the performance of school and student will improve through the self-efficacy improvement plan presented in this study.
