The skin barrier function is one of the vital functions. Horny layer and epidermis among various skin layers play an important role in protecting body from environmental insults. Stratum corneum is completely formed by differentiation processes from the basal layer and newly formed corneocytes push the older ones from skin surface. In this study we investigated changes of various parameters - capacitance, transepidermal water loss (TEWL), pH and amount of removed corneocytes - according to the stratum corneum's depth. We removed the stratum corneum using tape stripping technique. We found that uppermost stratum corneum play an important role in skin surface moisturization and lower stratum corneum in protecting transepidermal water loss. In addition, skin pH is more acidic than surface pH. In the stratum corneum, skin pH is mote acidic in the deeper layer. Furthermore amount of removed corneocyte is also decreased according to depth because of stronger cell-cell union strength. From these results we suggest that stratum corneum has different characteristics depending on their position.

Purpose: The purpose of this study was to examine the effect of a maternal self-efficacy promotion program for Korean primiparas on maternal confidence and mother-infant interaction. Method: This study was non-equivalent quasi-experimental research with a control group selected by purposive sampling. Based on Bandura’s (1986) self-efficacy theory, the research team developed the maternal self-efficacy promotion program. The program included achievement experiences, verbal persuasion, and vicarious experiences. The program was provided through face-to-face teaching at the time of discharge, counseling sessions over the telephone, and a home visit. Subjects also learned about parenting skills using a videotape developed by the research team. Sixteen primiparas were recruited to the experimental group at one hospital in Kyongi province, and fifteen primiparas who were matched according to socioeconomic status were recruited to the control group at a postpartum care center in the same province. Results: Subjects in the experimental group demonstrated significantly higher maternal confidence and mother-infant interaction than those in the control group. Conclusion: The maternal self-efficacy promotion program appears to be an effective nursing intervention for parenting of first-time mothers in Korea.

Innovation becomes norm rather than exception in today's business, and accordingly firms are working on how to make their employees to work smarter using information systems and technologies. Smart work demands virtual collaboration and cooperation among team members in different places and different time. Sharing of knowledge among team members in these innovative activities are critical in every sense for the successful performance. This study explores the antecedents of knowledge sharing among team members in team-based innovation activities. Five factors (pleasure of knowledge sharing, self-efficacy, management support, rewards, and system usage) are identified through extant review of literature and an instrument is adopted and validated from previous studies. The instrument is adminitered against 138 individuals in and across 54 teams in a telecommunication firm. Except self efficacy, all the paths in the proposed research model is confirmed with different levels of relational coefficients towards the levels of knowledge sharing and innovation activities in teams. Surprisingly, findings indicate that intrinsic pleasure of sharing is most critical than management support, organizational rewards or system usage. This study fills the research gap in team management. Findings provide important implications for managing teams in coming virtual and smart environment.

Purpose: The purpose of this study was to identify the effects simulation-based education combined team-based learning (SBE combined TBL) compared to simulation-based education (SBE) on undergraduate nursing students. Methods: A non-equivalent control group design with pre-and posttest measures was used. The participants in the study were 181 students. The SBE combined TBL group consisted of 84 senior students in 2013, and the SBE group consisted of 97 seniors in 2014. Collected data were analyzed using chi-square, independent t-test and ANCOVA with the statistical package SPSS 22.0 for Windows. Results: There was a significant improvement in communication skills, nursing performance confidence, team efficacy, and team performance scores in the SBE combined TBL group compared to the SBE group (t=2.45, p=.015; F=4.30, p=.040; t=3.06, p=.003; t=8.77, p<.001). However, there was no statistically significant difference in self-directed learning between the groups. Conclusion: SBE combined TBL compared to SBE is an effective teaching and learning method to enhance various positive educational outcomes for nursing students. Therefore, we suggest that future studies investigate the development of an integrated course in which team-based learning is applied to theoretical sessions and simulation-based training.

Purpose: In-hospital cardiac arrest is rare, but often results in high mortality rates. Early and effective cardiopulmonary resuscitation (CPR) is crucial for survival and nurses are often the first responders. This study aimed to investigate how inter-professional attitudes and educational burdens affect self-efficacy related to CPR performance following team-based CPR simulation training. Methods: This retrospective observational study analyzed data from a satisfaction survey conducted after team-based CPR training sessions between January and November 2022. Of the 454 nurses surveyed, 238 were included in the study after excluding those with ambiguous responses. Multiple regression analysis was performed to assess factors influencing CPR self-efficacy. The factors examined included inter-professional attitudes and educational burden. Results: Higher levels of inter-professional attitudes, particularly regarding teamwork roles and responsibilities, lower educational burden, and a positive perception of CPR competence were all associated with improved CPR-related self-efficacy. Participants who reported higher engagement in teamwork, lower task load, and greater confidence in their CPR abilities demonstrated higher self-efficacy in performing CPR. Conclusion: Enhancing the competencies of nurses who may act as initial responders in CPR situations within or outside hospital settings can help save lives and support public health.

The purpose of this study was to test the effects of simulation-based delivery nursing practice on proactivity of problem-solving, clinical Performance and team efficacy in nursing college students. This study conducted with a quasi-experimental one group pretest-posttest design. The subjects of the study were those who participated in the pretest-posttest survey among third graders in nursing who took a simulation-based delivery nursing practice class at S university in D city, and finally, data from 78 students who completed the survey were analyzed. Data collection was conducted from August 30, 2022 to October 28, 2022, and data were analyzed using SPSS 27.0 program. The findings suggest that simulation-based delivery nursing practice had a positive effect by significantly increasing on problem-solving proactivity, clinical performance ability, and team efficacy. However, There are limitations in generalizing the study results. therefore based on a sufficient number of samples, the effects should be verified through randomized controlled pre-and post-test and, To determine whether the effects are consistent, it will be necessary to follow up in the long term.

Transformational and authentic leadership are known to create positive effects on follower's various outcomes, like job satisfaction and organizational commitment. We're mostly interested in testing positive effects of transformational and authentic leadership of cabin team leaders in airline industry, because their leadership tends to have strong and immediate impact on cabin crew's quality of customer services. We figured that cabin team leader's transformational and authentic leadership had positive effects on crew member's job satisfaction and organizational commitment. And, these positive relationships were at least partially mediated through crew member's self-efficacy and LMX. Based on these positive results, we discussed several theoretical and practical implications for developing effective leadership across cabin team leaders in airline services industry.

Leader-Member Exchange (LMX) model of leadership has suggested that members within the same work team are differentiated in terms of their level of the quality of leader member relationships. However, the differentiation in leader member relationships has not been examined for its possible team-level effects. In this study, the possible impact of this role differentiation on team members' affective reactions was explored. As hypothesized, teams whose members experienced higher level of LMX tended to have higher overall job satisfaction, organizational commitment, and team efficacy. Contrary to expectation, however, the team-level mean on LMX was not related with team-level variability on LMX. Based on these findings, several theoretical and practical Implications are discussed.
