Objective: To gather the opinions of hands-on workers for successful introduction of the Development Safety Update Report (DSUR) according to a five-year comprehensive plan for clinical trial development [Ministry of Food and Drug Safety, 2019]. Methods: We conducted a survey on considerations that industry stakeholders may have related to the enforcement of the DSUR. A questionnaire was distributed among pharmacovigilance specialists from 13 pharmaceutical companies in South Korea on June 4, 2020. The questionnaire comprised two sections: 1) current status of the Drug Safety Data Management System and 2) considerations on the implementation and management of the DSUR. Results: All respondents have agreed the introduction of DSUR is inevitable for regulatory harmonization and safety of trial subject. However, most respondents (85%) felt concern about additional workload with DSUR implementation. They answered that format and operation system of DSUR should be harmonized with those of international standards and authorities need to minimize double burden due to related report. Conclusion: All respondents asserted that domestic DSUR should be harmonized with International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) E2F guidelines. Respondents from global companies also suggested regulatory authorities allow DSUR written in English to replace Korean version considering their deadline for submission. Moreover, every respondent agreed regulatory authorities need delicate effort when implementing mandatory submission of DSUR to ensure that even small pharmaceutical companies with no experience in DSUR can comply with the system.

Purpose : This study aimed to identify the status of intrahospital transport (IHT) of critically ill patients and provide baseline data to form recommendations for safer transport. Methods : Data were collected from 141 intensive care unit (ICU) nurses who attended national conferences between February and August, 2018. The collected data were analyzed using descriptive statistics and ANOVA, and post-hoc analysis was conducted with the Scheffé and Games-Howell tests. Results : Of the nurses surveyed, 61.7% answered that their workplace had a transport guideline. In terms of the experience of ICU nurses, 31.2% of respondents answered that they had received training on IHT. This result indicated that the degree of implementation of the guidelines for IHT was generally high, but some, including guidelines on personnel, equipment, and monitoring, were not. Guidelines of IHT were well observed when the institutes had specific guidelines for IHT of critically ill patients with specified transport grades, a scoring system to assess stability of a patient, a checklist and a protocol for action in case of problems, and when healthcare providers were provided with training. Conclusion : These results suggest that organized infrastructure, such as a transport guideline with transport grades, a checklist to improve the implementation of guidelines, and a protocol for coping with a problem, should be provided for safe transport. Additionally, effective education and evaluation to improve the competency of staff participating in the transport of patients will help reduce the occurrence of adverse events in intensive care transport in hospitals and promote patient safety.

In March 2007, Korea's Ministry of Construction & Transportation (MOCT) established "Guidelines on the Computerization and Use of Geotechnical Investigation Results," which took effect as official instructions. The 2007 Geotechnical Information DB Construction Project is underway as a model project for a stable geotechnical information distribution system based on the MOCT guidelines, accompanied by user education on the geotechnical data distribution system. This study introduces a geotechnical data entry system characterized by the standardization of the geotechnical investigation form, the standardization of metadata for creating the geotechnical data to be distributed, and the creation of borehole space data based on the world geodetic system according to the changes in the national coordinate system, to define a unified DB structure and the items for the geotechnical data entry system and to computerize the field geotechnical investigation results using the MOCT guidelines. In addition, the present operating status of the geotechnical data entry system and entry data processing statistics are introduced through an analysis of the model project, and the problems of the project are analyzed to suggest improvements. Education on, and the implementation of, the model project for the geotechnical data entry system, which was developed via the standardization of the geotechnical investigation results form and the metadata for institutions showed that most users can use the system easily. There were problems, however, including those related to the complexity of metadata creation, partial errors in moving to the borehole data window, partial recognition errors in the installation program for different computer operating systems, etc. Especially, the individual standard form usage and the specificity of the person who enters the geotechnical information for the Korea National Housing Corporation, among the institutions under MOCT, required partial improvement of the geotechnical data entry system. The problems surfaced from this study will be promptly addressed in the operation and management of the geotechnical data DB center in 2008.

This study examines teachers' implementation of strategies to modify the aggressive behavior of students with intellectual disabilities in Saudi Arabia, to determine the obstacles to their real-world execution. In addition, it presents potential approaches to overcome the obstacles to implementing strategies with this group of students. The research employed a qualitative design using semi-structured interviews as a data collection tool and applied a thematic analysis. The study population comprised 35 teachers of students with intellectual disabilities and the study sample numbered six teachers. The interviews were conducted via different methods: three by phone, two face-to face, and one using the Zoom platform. The results revealed inadequate understanding among teachers of intellectual disability and behaviour modification strategies, and this affected their capacity to develop plans that were compatible with the needs of students with intellectual disability. The findings also identified multiple obstacles that impede teachers' implementation of strategies to modify aggressive behaviour among students with intellectual disabilities; the most important being the lack of input from a psychological specialist when developing programs to modify aggressive behaviour. In general, it is apparent that programs for modifying aggressive behaviour are neither structured nor complementary, due to the scarcity of administrators with sufficient knowledge and familiarity with the characteristics and personalities of students with intellectual disabilities. This study presents several recommendations, the most important of which is that teachers of students with intellectual disability should develop themselves through training courses to enable them to deal with these students and create treatment plans that include strategies and clear steps to modify the aggressive behaviour of students with intellectual disabilities. To support teachers, it is also necessary to remove the obstacles facing education centres by providing financial support to create an environment in which they can access the required devices and equipment in their classes.

Background: This study investigated the awareness and utilization of maternity protection and work-family balance support policies among dental hygienists in dental hospitals and clinics. Methods: We surveyed 200 dental hygienists. Twenty-two who did not meet the inclusion criteria were excluded, leaving 178 participants for analysis. The self-administered 48-item questionnaire gathered information on demographics, workplace details, policy awareness, government knowledge, and suggestions for improvement. Results: Awareness of maternity and family support programs significantly differed with age, marital status, number of children, and clinical experience. Dental hygienists in general hospitals and university hospitals reported greater ease of utilizing these policies compared to those in dental clinics. Among the participants, 27.7% took pre- and post-maternity leave, 26.6% took parental leave, 16.9% had reduced working hours during pregnancy, 15.8% had reduced working hours during childhood,and 8.5% during family leave. To promote program uptake, participants suggested mandatory implementation across workplaces (68.4%), expanded support for substitute workers (48.6%), and increased education and promotion of government support (42.4%). Conclusion: While most dental hygienists were aware of the Maternity Protection and Work-Family Balance Assistance Policy, utilizing it proved challenging due to several factors. Organizational policies or practices may not fully implement this policy, while workplace culture could discourage its use. Unfair treatment and the lack of available substitutes further hindered access. To prevent career interruptions for dental hygienists due to pregnancy, childbirth, childcare, and family care, and to maintain career continuity, the dental community and government should establish a multifaceted social support system. This system should prioritize several key areas: strengthening policy promotion, fostering a family-friendly atmosphere, improving management and supervision of policy implementation and developing a robust support system for substitute personnel.

Recently, the application of microservice architecture has been increasing as information systems have shifted to cloud environments. The purpose of this paper was to analyze the case of applying microservice architecture to MES in the manufacturing field, summarize the results of how it was applied in practice, and find out the effects of the application. Based on the improvement project by applying microservice architecture to the existing steel manufacturing MES, 11 principles of microservice application were derived through literature research, and the implementation process and results were summarized according to these principles. In addition, through a comparison of systems in the service industry and the manufacturing industry, we investigated why the application of microservices was more active in the service industry and whether the application in the manufacturing industry can be expected to have the same effect. We also evaluated the results and changes in the overall system after implementation. In particular, we analyzed the SR (Service Request) processing status of users' requests for system changes and operators' requests to see how much the lead time was reduced. The results showed that 8 out of 11 microservice application principles were properly implemented according to the principles, but the remaining 3 were not applicable due to practical difficulties and organizational circumstances. Despite not following all of the principles, the project was able to be implemented without any problems, and the most noticeable change as a result of the microservices architecture was that the lead time was reduced by 9 days compared to the previous system. This proves that it is possible to quickly adapt to customer requirements, and it also proves that the system is more flexible and scalable than the existing monolithic system.
