As knowledge management is recognized as an important factor for organizational performance, organizations are increasing their investment in knowledge management policies and technologies. The purpose of this study is to suggest positive and negative causes on the intention to share knowledge through a using knowledge management system(KMS) and to suggest the effect of organizational sharing climate. Research models and hypotheses were presented through previous studies, and 417 samples were obtained through the survey for employees of organizations that adopted a KMS. As a result of the analysis, usefulness and ease of use of the KMS had a positive effect on the intention to share knowledge, and task conflict and ambiguity had a negative effect. The knowledge sharing climate was found to be an antecedent for the technology acceptance model and task stress. In addition, task stress moderated the effect of usefulness and ease of use with the intention to share knowledge using KMS. The results suggested the direction to be pursued at the organizational level for the continuous use of KMS.

As information is recognized as an important asset of an organization, organizations are increasing their resource input for knowledge management. In particular, the enterprise content management system(ECMS) is a solution for organization-oriented content management, and it has high utility by helping to achieve business performance through systematic utilization of content and improve the level of internal information security. The purpose of this study is to suggest a plan to improve the intention to use organizational employee's ECMS and to suggest the effect of the relationships between information system quality characteristics and work environment characteristics on intention to use. In this study, a research hypothesis was presented based on previous studies, a questionnaire was conducted on workers of organizations that adopted an ECMS, and the hypothesis was verified by applying structural equation modeling. As a result of the analysis, information and service quality of the ECMS and task interdependence increased the intention to use, but task conflict decreased the intention to use. In addition, task interdependence and task conflict moderated the positive relationship between the quality factors of the ECMS and the intention to use it. This study has implications in terms of suggesting the direction of the organization's behavior through factors that increase the use of ECMS.

Without any validation of the incompressible assumption, most of previous studies on cavitation flow and its noise have utilized numerical methods based on the incompressible Reynolds Average Navier-Stokes (RANS) equations because of advantage of its efficiency. In this study, to investigate the effects of the flow compressibility on the Tip Vortex Cavitation (TVC) flow and noise, both the incompressible and compressible simulations are performed to simulate the TVC flow, and the Ffowcs Williams and Hawkings (FW-H) integral equation is utilized to predict the TVC noise. The DARPA Suboff submarine body with an underwater propeller of a skew angle of 17 degree is targeted to account for the effects of upstream disturbance. The computation domain is set to be same as the test-section of the large cavitation tunnel in Korea Research Institute of Ships and Ocean Engineering to compare the prediction results with the measured ones. To predict the TVC accurately, the Delayed Detached Eddy Simulation (DDES) technique is used in combination with the adaptive grid techniques. The acoustic spectrum obtained using the compressible flow solver shows closer agreement with the measured one.

As knowledge management is recognized as a core value of organizations, organizations are increasing their investment in policies and technologies for knowledge management. However, since SMEs have relatively few resources to support knowledge sharing, which is the core of knowledge management, there is a possibility that continuous knowledge management will be difficult. This study suggests the negative motivation(job burnout) on the knowledge hoarding of SME employees and the conditions to be improved at the organizational level (shared goal, knowledge sharing culture, and person-organization fit). In this study, a hypothesis was presented through a study related to transaction theory to explain the stress in the relationship between the organization and the individual. This study collected samples through a questionnaire targeting workers of SMEs with knowledge management policies. In addition, the hypothesis was verified by performing structural equation modeling. As a result of the study, shared goal and knowledge sharing culture reduced knowledge hoarding through mitigating job burnout. In particular, person-organization fit moderated the relationship between shared goal, knowledge sharing culture, and job burnout. The study presents academic and practical implications in terms of suggesting factors to mitigate the knowledge hoarding of employees for continuous knowledge management of SMEs.

The purpose of this study is to empirically analyze the effect of individual perception of artificial intelligence and the level of digital literacy on the acceptance of artificial intelligence-based public services. For empirical analysis, a research model was set up based on the technology acceptance model and planned behavior theory using survey data of 2017 and analyzed through structural equations. To summarize the results of the analysis, firstly, the positive perception of individuals about artificial intelligence technology plays a role in reinforcing attitudes toward benefits and reducing concerns about public service in which artificial intelligence technology has been introduced. Secondly, the level of digital literacy reinforces both benefits and concerns about artificial intelligence technology, but it was found that the intention to use public services was reinforced through the benefits of artificial intelligence technology perceived by individuals, rather than privacy concerns about artificial intelligence technology. Thirdly, it was confirmed that the perceived benefits of individuals on artificial intelligence technology reinforced the intention to use public civil services, and privacy concerns negatively influenced the intention to use. It was confirmed that the influence of a perceived ease of use and usefulness, as opposed to privacy concerns, further reinforces the intention to use. Both citizens' positive perceptions regarding the accuracy and reliability of information provided through artificial intelligence technology and institutional complementation of responsibility for errors caused by artificial intelligence technology are strengthened, and technical problems related to privacy protection are solved.

This study aims to examine the mediating effects of paternal depression on the relationship between traditional gender role attitudes and the perceived maternal gatekeeping roles of fathers with young children. For this purpose, a survey was conducted by 366 married fathers who raises at least one child who is under seven years old. Mplus 7.0 was used to analyze the structural equation model, and the result showed that higher traditional gender role attitudes relate to more depressive symptoms, higher perceptions of maternal gate closing and lower perceptions of maternal gate opening. Also, more depressive symptoms were related to higher perceptions of maternal gate closing and lower perceptions of maternal gate opening. Additionally, the partial mediation effects of depression were observed in the relationship between traditional gender role attitudes and maternal gate keeping. Based on the findings, implications for therapeutic interventions were discussed, and recommendations for future research are presented.

The purpose of this research is to analyze generation gap of positive effects on character strength for full life of adults in Korea and to verify mediating effect of volunteering from character strength in this roots. To test this effects, there was an investigated differences of perception on character strength, volunteering and full life from 1,405 Koreans. Then had set up the influence model of character strength on full life between generation, and verified the model through structural equation. Therethrough first, there was statistical significant between generations except the variables of trust, full life and meaning of life. Second, full life was positively influenced by character strength in early adulthood. Third, volunteering had fully mediated from character strength to full life in post middle aged adults, but had partially mediated in early adulthood. This will help acquaint us with importance of accompany with volunteering at character strength than character strength directly connects to full life. Based on these results, we are treated on importance of mediating volunteering effects and influences of character strengths on full life in Korean society.

As forest fires' scale has increased, they have become disasters that destroy not only forests but also property, human psychological balance, and even human lives. As a result, governmental support has become a crucial part of the forest fire restoration process. Quickly restoring victims' quality of life (QOL) from not only an ecological perspective but also from their human perspective has become an important goal. Therefore, through structural equation modeling, this study analyzed effects of government support, post-traumatic stress disorder (PTSD), and resilience on 195 Uljin and Samcheok forest fire victims' QOL. In the final research model, the total standardized effect on QOL of government support to PTSD and resilience was found to have significant effect (0.417). By path, the effect of government support on QOL through resilience was verified as 0.172. Examination of the path between latent variables revealed that resilience had the greatest influence on QOL, and government support had a significant effect, thus confirming that they were the main factors affecting QOL.

As information and communications technology-based "smart hospitals" and "digital healthcare" have become a hot topic in the healthcare field, hospital mobile apps are gaining attention; but, the utilization rate is low due to lack of publicity, unstable systems, and late updates. In this situation, systematic research is needed to increase the utilization rate of hospital mobile apps, but related research has been rare. Therefore, this study integrates the information systems success model (ISSM) from the technical perspective and the expectation-confirmation model (ECM) from the cognitive perspective to demonstrate the influence mechanism on the continuous use intention of hospital mobile apps. For this purpose, an online survey was conducted among 181 Korean adults who have used hospital mobile apps. The results of the structual equation modeling showed that most of the quality factors have significant effects on expectation confirmation, perceived usefulness, and satisfaction. Additionally, expectation confirmation significantly affects perceived usefulness and satisfaction, and both perceived usefulness and satisfaction significantly affect the continuous use intention of hospital mobile apps. This study is of importance in that it integrates the ISSM and ECM and applies them to the context of using hospital mobile apps, which are underutilized in the healthcare field, and provides practical implications for increasing the utilization rate of hospital mobile apps and operating effective and efficient services through the findings.
