The purpose of this study is to empirically examine organizational change for a technological application of the fourth industrial revolution. The theoretical background of this study utilized organizational change management, the fourth industrial revolution, technological innovation, and voluntary acceptance. This research method used structural equations, cluster analysis, and analysis of variance. According to the results of the study, the organizational implement system, organizational leadership, and organizational operating system provided a positive effect on the voluntary technology acceptance of organization members. The voluntary technology acceptance provided a positive effect on the effectiveness of individual task innovation. However, organizational institutionalization among the independent variables did not affect voluntary acceptance. All independent variables except the organizational institutionalization had a partial mediating effect in the mediating effect verification. Meanwhile, The three groups by the cluster analysis were classified as new technology apathy, preference, and anxiety groups, and differences appeared among groups in the importance of organizational change variables. The organizational implement system in the technology apathy group and the organizational operating system in the technology anxiety group have a positive effect on voluntary technology acceptance. The technology preference group shows that a positive effect on organizational leadership and a negative effect on organizational institutionalization for voluntary technology acceptance. This study analyzed the technology application of the fourth industrial revolution in the organization based on the theory of organizational change. There has been reexamined the organizational change theory based on the new technology acceptance by the change of external environment in the fourth industrial revolution and the importance of technology innovation. As a practical implication, firms that are interested in a new technology of the fourth industrial revolution should prioritize preparing an implementation system when designing organizational changes.

In recent years, due to the demand for operating efficiency and cost reduction of industrial facilities, remote access via the Internet is expanding. the control network accelerates from network separation to network connection due to the development of IIoT (Industrial Internet of Things) technology. Transition of control network is a new opportunity, but concerns about cybersecurity are also growing. Therefore, manufacturers must reflect security compliance and standards in consideration of the Internet connection environment, and enterprises must newly recognize the connection area of the control network as a security management target. In this study, the core target of the control system security threat is defined as the network boundary, and issues regarding the security architecture configuration for the boundary and the role & responsibility of the working organization are covered. Enterprises do not integrate the design organization with the operation organization after go-live, and are not consistently reflecting security considerations from design to operation. At this point, the expansion of the control network is a big transition that calls for the establishment of a responsible organization and reinforcement of the role of the network boundary area where there is a concern about lack of management. Thus, through the organization of the facility network and the analysis of the roles between each organization, an static perspective and difference in perception were derived. In addition, standards and guidelines required for reinforcing network boundary security were studied to address essential operational standards that required the Internet connection of the control network. This study will help establish a network boundary management system that should be considered at the enterprise level in the future.

In lithium-sulfur (Li-S) batteries, encapsulation of sulfur in activated carbon (AC) materials is a promising strategy for preventing the dissolution of lithium polysulfide into electrolytes and enhancing cycle life, because instead of solid-liquid-solid reactions, quasi-solid-state (QSS) reactions occur in the AC micropores. While a high weight fraction of sulfur in S/AC composites is essential for achieving a high energy density of Li-S cells, the deterioration mechanisms under such conditions are still unclear. In this study, we report the deterioration mechanisms during charge-discharge cycling when the discharge products overflow from the AC. Analysis using scanning electron microscopy and energy-dispersive X-ray spectrometry confirms that the sulfur in the S/AC composites migrates outside the AC as cycling progresses, and it is barely present in the AC after 20 cycles, which corresponds to the capacity decay of the cell. Impedance analysis clearly shows that the electrical resistance of the S/AC composite and the charge-transfer resistance of QSS reactions significantly increase as a result of sulfur migration. On the other hand, the charge-discharge cycling performance under limited-capacity conditions, where the discharge products are encapsulated inside the AC, is extremely stable. These results reveal the degradation mechanism of a Li-S cell with micro-porous carbon and provide crucial insights into the design of a S/AC composite cathode and its operating conditions needed to achieve stable cycling performance.

Purpose: The purpose of this study was to identify the factors related to blood-borne infection prevention behaviors based on the risk perception of the health belief model among operating room nurses. Risk perception factors included perceived susceptibility, barriers, benefits, and perceived severity. Methods: Data were collected from 121 operating room nurses working in four different hospitals in Daejeon and Seoul from June 30 to May 11, 2016. Results: The mean age was 31.2 years, and the average years of clinical experience in operating room was 7.9 years. The mean score of knowledge was 13.15. The mean score of perceived susceptibility, barrier, benefit, and perceived severity were 3.76, 3.70, 3.95, and 4.64, respectively. Blood-borne infection prevention behaviors had positive correlation with perceived benefits (p=.010), but negative correlation with sensitivity (p=.009) and barrier (p=.012). The hierarchical regression model on infection prevention behavior was statistically significant (F=4.85, p<.001). The sixteen percent of variance in behavior was explained by age (${\beta}=.18$, p=.038), perceived benefit (${\beta}=.20$, p=.030), perceived susceptibility (${\beta}=-.25$, p=.005), and perceived barrier (${\beta}=-.18$, p=.042). Conclusion: In order to increase infection prevention behaviors among operating room nurses, there is a need for developing specific education program focusing on appropriate management of equipment, instruments, and environment in operating room. In addition, support from the hospital organization level need to be provided as well.

The purpose of this study was to explore employees' experiences of integrated services in Healthy Family and Multicultural Family Support Centers in Seoul. In-depth interviews were conducted with seven employees, including managers and heads of Healthy Family and Multicultural Family Support Centers. The interviews identified three themes: the direction of integrated service, the characteristics of the integration process, and the challenges of integrated service. For the direction of integrated service, the participants identified the integration center as a professional family services organization that provided customized services for different types of families. During the integration process, employees found it difficult to provide integrated services because few guidelines existed on operating an integration center that provided services to families with different characteristics and needs. However, they also explained positive aspects of integration, such as strengthening the business's capacity by expanding the organization. To improve integrated service, employees emphasized the expertise and appropriateness of the family services over the efficiency of the integration centers. They also stressed expansion as a role of a professional family services organization. These findings suggested that establishing a clear direction for integrated service as well as the roles of administrative support agencies is important for activating integrated services.

Four requirements for the operating and supporting system for sustainable landscape management will be discussed through this paper. The requirements are based on multiple case studies on the structure and the process of development of three organizations that have been contributing to the sustainable rural landscape management in Japan since 1989. The first requirement is that the residents should recognize regional problems and voluntarily organize a group which can properly deal with the problems. Secondly, members of the organization should have a solid grasp of the goal of their activities (or founding principal of the organization) and share it among themselves. Founding principal should include the history of natural circulation system in the area, cultural features and a future plan in association with human resources. Thirdly, the administration of the organization should be separated from the founder, the residents. The administration, such as business promotion, becomes more effective when consigned to a separate entity, not to the residents. Lastly, the interaction among separate entities is crucial to promote diverse activities for the local landscape management. The administrators and experts need to cooperate to draw a precise conclusion regarding the way of interaction. These requirements drawn from the Japanese case studies should be localized to the Korean circumstances for further adoption.
