The purpose of this study was to analyze the claim data of Health Insurance Review & Assessment Service to determine what factors affected the length of stay in patients aged 65 and older and undergoing total knee arthroplasty due to the principal diagnosis of gonarthrosis by the type of medical institutions. As a result of making an analysis, gender, age, medical security type, severity, residential area and the number of sickbeds were identified as the factors that influenced the length of stay in each type of medical institutions. At this point in time when an increase in the elderly population triggered by population aging and another subsequent increase in medical expenses put a heavy strain on household and national economy, it's necessary to consider how to shorten the length of stay and how to ensure the efficient management of sickbeds based on the findings of this study. In addition, this study is of significance in that it could be used as basic data on quality life-care for elderly patients by the introduction of a systematic management system geared toward lessening patient burden for medical expenses.

Bitcoin is an electronic money that does not rely on centralized institutions such as banks and financial institutions, unlike the world's paper currencies such as dollar, won, euro and yen. In Bitcoin network, a block with transaction details is generated by mining, and the message that the block has been created is broadcast to all participating nodes in a broadcasting method to secure reliability through verification. Likewise, the mining and block propagation methods in the Bitcoin network are greatly affected by the performance of the P2P network. For example, in the case of mining, the node receiving the reward for mining varies depending on whether the block is first mined in the network and the proof of mining is propagated faster. In this paper, we applied local characteristics and Round-to-Trip(RTT) measurement to solve the problems of the existing neighbor connection method and block propagation method performed in Bitcoin network. An algorithm to improve block propagation speed is presented. Through experiments, we compare the performance of the improved algorithm with the existing algorithm to verify that the overall block propagation time is reduced.

The use of service robots, particularly guide robots, is becoming increasingly prevalent in public institutions. However, there has been limited research into the interactions between users and guide robots. To explore the customer experience with the guidance robot, we selected 'QI', which has been meeting customers for the longest time, and collected all reviews since the service was launched in public institutions. By using text mining techniques, we identified the main keywords and user experience factors and examined factors that hinder user experience. As a result, the guide robot's functionality, appearance, interaction methods, and role as a cultural commentator and helper were key factors that influenced the user experience. After identifying hindrance factors, we suggested solutions such as improved interaction design, multimodal interface service design, and content development. This study contributes to the understanding of user experience with guide robots and provides practical suggestions for improvement.

As social and political paradigms change, public institution tasks and structures are constantly created, integrated, or abolished. From an effective record management perspective, it is necessary to review whether the previously established record classification schemes reflect these changes and remain relevant to current tasks. However, in most institutions, the restructuring process relies on manual labor and the experiential judgment of practitioners or institutional record managers, making it difficult to reflect changes in a timely manner or comprehensively understand the overall context. To address these issues and improve the efficiency of record management, this study proposes an approach using automation and intelligence technologies to restructure the classification schemes, ensuring records are filed within an appropriate context. Furthermore, the proposed approach was applied to the target institution, its results were used as the basis for interviews with the practitioners to verify the effectiveness and limitations of the approach. It is, aiming to enhance the accuracy and reliability of the restructured record classification schemes and promote the standardization of record management.

Interprofessional education (IPE) fosters knowledge, skills, and attitudes related to interprofessional collaboration (IPC) for safe, quality patient care. In recent years, the importance of IPC has extended beyond the medical field to local community settings. However, IPE has only recently been introduced and has yet to become widespread. This study reviews the origin and development of IPE in Korean medical education by comparing it with established models in other countries that provide useful insights into future directions for IPE in Korea. Dedicated institutions led the IPE effort in other countries; however, IPE initiatives in Korea were mainly driven by individual professors' and medical schools' interest and commitment, without structural support systems. An important finding of this study is that the lack of awareness and organizational support within the medical education community resulted in the absence of a mandatory curriculum for IPE, as it was omitted from the accreditation standards. For more organized adoption and implementation of IPE in Korea, this study suggests the need to widely communicate the importance of IPE to the medical community and the public. It is also imperative to establish leadership capable of guiding IPE, share materials through trusted institutions with IPE experience, and include IPE in the accreditation standards. These steps are essential for actively implementing IPE and meeting societal healthcare needs in Korea.

The research involved children and parents of primary school-aged children with cognitive development disorder, as well as scientific and pedagogical workers who organized the psychological and pedagogical principles for organizing distance learning. The purpose of the research lies in establishing how effectively children, parents and their teachers cope with online distance learning during the pandemic, as well as investigating the extent to which such educational technology affects the emotional and behavioural state of the child. The research methodology is based on complexity. In the course of the research, the method of pedagogical experiment was used; observation and questionnaire methods were also introduced; the descriptive method, analysis and synthesis were used to review the theoretical material. The hypothesis lies in the fact that distance online education increases academic difficulties, changes the behavioural and emotional picture of a child with cognitive development disorder; consequently, the behaviour and emotional background will be limited by certain parameters, and this requires the active involvement of parents and teachers in the distance work process. The results of the research have revealed that distance education causes a number of restrictions for children with cognitive development disorder, namely: concentration of attention has decreased, anxiety has increased, and sleep has worsened. Behavioural changes predicted increased restlessness and aggression. Parents and teachers have had methodological, academic and everyday difficulties; all participants in the educational process have been more limited in the conditions of online distance learning. difficulties and improving the behaviour and emotional states of all participants in the educational process.

This research provides a quantitative analysis on research articles published in PLoS ONE, a multidisciplinary open access journal, by authors affiliated with Korean institutions. Korean authors published more than 6,500 research ariticles in the mega journal between 2006 and 2019. Korea is ranked the top 11th place in terms of article publishing in the journal. Most articles by Korean authors are concentrated in the biomedical fields. In recent years, the overall production of PLoS ONE has decreased as authors migrated to competing mega journals such as Scientific Reports and BMJ Open. The change might have been affected in part by the delay in the review period and the dropping impact factor score. The open access share of the Korean PLoS ONE authors of more than 10 articles hovers around 30%. However, there is a significant variation among researchers reaching up to 50% discrepancies. Among altmetrics provided by PLoS ONE, the saves are highly correlated with the views and the citations. On the contrary, the shares show low correlation with other use metrics. A follow up, survey questionnarie based research involving researchers who have published in PLoS ONE is planned in order to investigate author motivation and experience in the review process.
