The purpose of this study was to identify the effects of online communication courses using role-play and group activities on the communication competence, self-efficacy and relationship competence of nursing students. The research design was a one-group pretest-posttest quasi-experimental study, and a total of 13 communication classes for 100 minutes each were conducted for first-year nursing students from September to December 2020. Communication competence, self-efficacy, and relationship competence of nursing students had improved significantly after online classes. According to the results of this study, it was possible to confirm the effects of classes in communication subjects applying various teaching methods to nursing students through online education platforms.

Nursing students who play a role as future nursing professions are provided with education through various teaching and learning methods in order to develop necessary competencies. The purpose of this study is to confirm the effect of nursing practice education using multimedia. A quasi experimental study with a nonequivalent control group pretest-posttest design was used, and the participants of the study were students from two nursing colleges, who received an educational intervention using multimedia as the experimental group and those without education were selected as the control group. Data collection was conducted immediately before and after educational intervention, and data analysis was performed using the SPSS 21.0 program by x²-test, Fisher's exact probability, and t-test. As a result of the study, the experimental group was statistically significant in self-efficacy (t=3.402, p=0.015), resilience (t=2.047, p=0.045) and performance confidence (t=2.128, p=0.018) compared to the control group. Through these results, we could confirm that multi-media practical education is effective educational method for enhancing nursing students' self-efficacy, resilience, and performance confidence. Therefore, in order to establish a systematization of the nursing profession, it is essential and should be continued for nursing students to use structured multimedia and core fundamental nursing skills.

Mitochondrial transplantation is a promising therapeutic approach for the treatment of mitochondrial diseases caused by mutations in mitochondrial DNA, as well as several metabolic and neurological disorders. Animal studies have shown that mitochondrial transplantation can improve cellular energy metabolism, restore mitochondrial function, and prevent cell death. However, challenges need to be addressed, such as the delivery of functional mitochondria to the correct cells in the body, and the long-term stability and function of the transplanted mitochondria. Researchers are exploring new methods for mitochondrial transplantation, including the use of nanoparticles or CRISPR gene editing. Mechanisms underlying the integration and function of transplanted mitochondria are complex and not fully understood, but research has revealed some key factors that play a role. While the safety and efficacy of mitochondrial transplantation have been investigated in animal models and human trials, more research is needed to optimize delivery methods and evaluate long-term safety and efficacy. Clinical trials using mitochondrial transplantation have shown mixed results, highlighting the need for further research in this area. In conclusion, although mitochondrial transplantation holds significant potential for the treatment of various diseases, more work is needed to overcome challenges and evaluate its safety and efficacy in human trials.

AC-PDPs have recently achieved good performance and their image quality can sufficiently compete with the LCD TV. However, it is necessary more effort to improve the luminance and luminous efficacy in the PDP technology. The gas mixture ratio plays a very important role in discharge characteristics, but the mechanism of gas discharge is complex and complicated. In this paper, we investigate the mechanism of gas discharge with Ne+Xe miture ratio through zero and two dimensional fluid simulation.

The voluntary knowledge creation plays an important role in achieving competitive advantage in the organization from the perspective of knowledge management. Although many companies have introduced the Knowledge Management Systems (KMS) for this purpose, they have not gained the expected benefits from those systems. One of the reasons for that is KMS have not provided organization members with sufficient intrinsic motivation about knowledge creation, diffusion and application. Therefore, this study proposes a concept called psychological knowledge ownership as intrinsic motivation factor that facilitates knowledge creation and examines its antecedents and consequences. The research results show that reputation, self-efficacy, and expertise sharing have impacts on psychological knowledge ownership, which in turn influences knowledge creation attitude. In conclusion, we discuss both theoretical and practical implications of this research and suggest its limitations.

Recently, the most frequently studied topics related to the fourth industrial revolution (FIR) are Big data, AI, Cloud Computing and Internet of Things- these four components are collectively known as the main components of the FIR (henceforth MCs). The MCs have a wide range of effects on workers' performance. As such it is imperative that these components are properly understood. This understanding will lead to a proper recognition of the attitudes that workers need to adopt to the MCs. Specifically, the attitudes of workers to several variables need to be examined, including importance, intention to use, belief in improvement, efficacy to use, and negative cognition. Each of these variables plays a role in determining how worker's performance in the FIR era will change. The performance-related variables such as self-efficacy, expectations, and acceptance of change are also crucial. These variables are related to creation of new opportunities, and can greatly influence performance in the FIR era. This study explains how specific attitudes to MCs improve performance-related factors for FIR. The adoption of these attitudes will ultimately lead to more successful adaption to the FIR era.

The sphenopalatine ganglion (SPG) is a parasympathetic ganglion, located in the pterygopalatine fossa. The SPG block has been used for a long time for treating headaches of varying etiologies. For anesthesiologists, treating postdural puncture headaches (PDPH) has always been challenging. The epidural block patch (EBP) was the only option until researchers explored the role of the SPG block as a relatively simple and effective way to treat PDPH. Also, since the existing evidence proving the efficacy of the SPG block in PDPH is scarce, the block cannot be offered to all patients. EBP can be still considered if an SPG block is not able to alleviate pain due to PDPH.

This study analyzes the factors affecting user resistance to ERP in Vietnam, including the factors related to the cultural values of the users, which is rarely dealt in the previous ERP research. A research model is developed based on Klaus and Blanton [2010] and Hofstede [2011], consisting of the independent variables ('cultural value', 'system', 'organization', and 'process' related variables), a dependent variable ('user resistance to ERP') and a moderating variable ('self efficacy'). Major results of study include (1) users with high degree of uncertainty avoidance and femininity regard ERP as potential threat to their job and are likely to resist to ERP; (2) By training the users with high level of femininity to enhance their self efficacy, the degree of resistance to ERP can be reduced; (3) For ERP to be utilized successfully, systems should be developed in such a way in which working with ERP is not regarded as complex and difficult; and (4) communication and training play an important role in reducing the resistance of users.

Restorative effect of forest settings is an emerging issue in the field of forestry. It is also the central question facing those currently engaged in the psychotherapeutic interventions is which treatments work. This study was performed to investigate the efficacy of forest experience on alcoholics' depression. Among 531 participants in forest healing camps, 47 alcoholics who participated all three sessions of the camps were selected for this study. Using pre-test and post-test group design with Beck Depression Inventory (BDI), mean changes in alcoholics' depression by completion of the camp was measured. The result of this study indicated that the 3-session of forest camp played significant role in reducing participants depression levels (i.e., positive changes in depression scores).
