With the spread of technology in the 4th Industrial Revolution, the defense industry in South Korea is getting developed into an industrial structure in which high-tech technologies are concentrated. As the importance of defense technology has gradually increased, the government has enacted the Defense Technology Security Act and required to build a protection system for institutions that possess or manage defense technology. In order for the target institution to introduce a protection system, it is necessary to identify the defense technologies that are protected and to ensure systematic data management. In order to cope with this, we derived master data items for data management and analyzed the implementation types of defense technology master data system suitable for the defense industry environments. The derived method identified the defense technology master data, such as primary and secondary master data, and through AHP analysis, Co-existence type was suitable as the target model for the master data management system. We expect that stronger defense technology security policy will be implemented through the defense technology MDM system.

The purpose of this study is to explore the meaning and essence of the learning experiences of K University students majoring in educational school librarianship. In order to achieve the purpose of the research, an open-ended question-based focus group interview was conducted for 12 major students who had graduated from K University's master's degree course within two years. By analyzing the contents of the answers, 9 themes, 35 categories, and 104 concepts were derived from the learning experience in the master's course. Looking at the main analysis results for each area, the motive for entering the master's course was to acquire a librarian teacher qualification, which is a condition in applying for the employment examination. The Satisfaction with the learning experience was an average of 7.66 out of 10 points. In addition, the most dissatisfied parts during the master's course was the contents of the subjects and classes that were not helpful in the operation of the school library and the employment examination for librarian teachers, therefore the response was that improvement is necessary for the future development of the librarian master's degree curriculum.

Purpose: The purpose of this study is to derive a plan to establish a more sophisticated master plan so that the direction of master plan study can be sustained in the mid to long term. Methods:: Compare and analyze the differences between the master plan and the design to identify causes and problems. First, after establishing the master plan, compare the expansion area, net area per bed, and service area with the design drawing of the first project to determine the degree of recovery to the level required by the recent medical environment. Second, the possibility of responding to future internal changes is reviewed by comparing and analyzing the arrangement and connection method of extension buildings. Third, comparing the difference between the project following the first project and the phased of masterplan. Results: The first one is that continuous participation of person or group with high understanding of the master plan. Second, establishing a master plan and proceeding with the project through the determination of the correct business budget. Third, a specific area of the mechanical and electrical room suitable for the size and purpose of the hospital should be presented, and research on the arrangement method should be conducted. Finally, the feasibility of the hospital's own plan for securing parking facilities should be accurately investigated. Implications: It is important for the hospital to recover from the past to the present and respond to the future that the direction of the master plan continues after the establishment.

This paper creates a standard node for acquiring sensor data from various industrial sensors (IoT/non-IoT) for the establishment of Smart Factory Digital Twin, and provides inter-compatible data by linking zones by group/process to secure data stability and to ensure the digital twin (Digital Twin) of Smart Factory. The process of the Zone Master platform contains interface specifications to define sensor objects and how sensor interactions between independent systems are performed and carries out individual policies for unique data exchange rules. The interface for execution control of the Zone Master Platform processor provides system management, declaration management for public-subscribe, object management for registering and communicating status information of sensor objects, ownership management for property ownership sharing, time management for data synchronization, and data distribution management for Route information on data exchange.

The quality of subgroup analyses (SGAs) in chronic non-cancer pain trials is uncertain. The purpose of this study was to address this issue. We conducted a comprehensive search in MEDLINE and EMBASE from January 2012 to September 2018 to identify eligible trials. Two pairs of reviewers assessed the quality of the SGAs and the credibility of subgroup claims using the 10 criteria developed by Sun et al. in 2012. The associations between the quality of the SGAs and the studies' characteristics including risk of bias, funding sources, sample size, and the latest impact factor, were assessed using multivariable logistic regression. Our search retrieved 3,401 articles of which 66 were eligible. The total number of SGAs was 177 of which 52 (29.4%) made a subgroup claim. Of these, only 15 (8.5%) were evaluated as being of high quality. Among the 30 SGAs that claimed subgroup effects using an appropriate method of performing interaction tests, the credibility of only 5 were assessed as high. None of the subgroup claims met all the credibility criteria. No significant association was found between the quality of SGAs and the studies' characteristics. The quality of the SGAs performed in chronic pain trials was poor. To enhance the quality of SGAs, scholars should consider the developed criteria when designing and conducting trials, particularly those which need to be specified a priori.
