The purpose is to improve the future clinical competence of medical personnel, which is directly linked to national health. Methods: With papers and patents published up to 2011 as the objects, 438 papers were extracted from "Web of Science" and 313 patents were extracted from the WIPS database (DB). Descriptive analysis and network analysis were conducted on the annual developments, academic journals, and research fields of the papers, patents searched were subjected to quantitative analysis per application year, nation, and technology, and an activity index (AI) was calculated. Results: First, research on medical learning support tools has continued to increase and is active in the fields of computer engineering, education research, and surgery. Second, the largest number of patent applications on medical learning support tools were made in the United States, South Korea, and Japan in this order, and the securement of remediation technology-centered patents, rather than basic/essential patents, seemed possible. Third, when the results of the analysis of research trends were comprehensively analyzed, international research on e-PBL- and medical simulation-centered medical learning support tools was seen to expand continuously to improve the clinical competence of medical personnel, which is directly linked to national health. Conclusions: The KM learning support tool model proposed in the present study is expected to be applicable to computer-based tests at KM schools and to be able to replace certain functions of national KM doctor license examinations once its problem DB, e-PBL, and TKM simulator have been constructed. This learning support tool will undergo a standardization process in the future.

FEM analysis is essential to shorten the development time and reduce the cost for developing high-performance machine tools. Mount joint parts play important role to ensure static and dynamic stability of machine tools. This paper suggests a computational modeling of mount joint part of machine tools. MATRIX27 element of ANSYS is adopted to model mount joint parts. MATRIX27 allows the definition of stiffness and damping matrices in matrix form. The matrix is assumed to relate two nodes, each with six degrees of freedom per node. Stiffness and damping values of commercial mount products are measured to build a database for FEM analysis. Jack mounts with rubber pad are exemplified in this paper. The database extracted from the experiments is also used to estimate of stiffness and damping of untested mounts. FEM analysis of machine tools system with the suggested mount computational model is performed. Static and dynamic results prove the feasibility of the suggested mount model.

This study proposes a web-based remote monitoring system for evaluating degradation of machine tools using ART2(Adaptive Resonance Theory 2) neural network. A number of studies on the monitoring of machine tools using neural networks have been reported. However, when normal condition is changed due to factors such as maintenance, tool change etc., or a new failure signal is generated, such algorithms need to be entirely retrained in order to accommodate the new signals. To cope with such problems, this study develops a remote monitoring system using ART2 in which new signals when required are simply added to the classes previously trained. This system can monitor degradation as well as failure of machine tools. To show the effectiveness of the proposed approach, the system is experimentally applied to monitoring a simulator similar to the main spindle of a machine tool, and the results show that the proposed system can be extended to monitoring of real industrial machine tools and equipment.

The purpose of this study was to explore research trends in sleep from infancy through to adolescence. To achieve this, an examination was conducted of sleep research published in Korea based on the publication year, developmental stages of the study participants, research designs, measurement tools, and research topics. A total of 362 academic journal articles and theses/dissertations published in Korea up until 2023 were selected. In terms of publication year, the first study was conducted in 1967 and the field became more active from 2010 onwards. The age group studied the most was adolescents, with cross-sectional research being the most common study design. Regarding sleep measurement tools, most scales measuring sleep in infants, preschoolers, children, and adolescents were developed abroad, then adapted or validated in Korea, or were modifications of adult scales tailored for specific studies. Lastly, in terms of research topics, the most common focus was the relationship between sleep and developmental characteristics, particularly its effects on emotional development. Based on these results, future research could focus on developing sleep-related intervention programs and measurement tools.

Recently because the IS development project is large scale and complicated, the necessity of tools that can manage effectively smooth communications and the harmonized project between the interested parties is exposed. According to this fact, many companies are investing enough to the PMS (Project Management System) for the sake of the systematic management of the IS development project, and also this PMS is emerging as one of the indispensable tools for the successful IS development project by casting off from a auxiliary means for the past project management. However, as had been expected, whether the introduction of the PMS is possible to facilitate communications within a project team, and a main motivation that can derive individual performance and organizational performance that participated in the IS development project is induced or not are not verified still empirically and apparently. With respect to this, a survey was conducted to examine how PMS quality affected user satisfaction, communication, individual performance and project performance. The effects of the data gathered were verified by structural equation model analysis.

The Web-based simulation was introduced for conducting simulation experiments in the Internet and the Web. Due to the use of the Java language, the Web-based simulation can have such characteristics as reusability, portability, and the capability of execution on the Web. Most of existing Web-based simulation tools have focused mainly on the development of the runtime simulation libraries and mechanisms on the Web. Thus, the model development work in such Web-based simulation tools still requires hand-written coding of model developers. This paper presents a visual model development environment for the Web-based simulation. The proposed environment provides a framework for model development and animation. To show the effectiveness of the proposed environment, we perform simulation experiments for transaction routing algorithms in a distributed transaction processing system.

Diagnostics, vaccines, and drugs are indispensable tools and control measures employed to overcome infectious diseases such as coronavirus disease 2019 (COVID-19). Diagnostic tools based on RT-PCR were developed early in the COVID-19 pandemic and were urgently required for quarantine (testing, tracing and isolation). Vaccines such as mRNA vaccines and virus-vectored vaccines were also successfully developed using new platform technologies within one year after identifying severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as the causative agent of COVID-19. Drug development has been conducted in various ways including drug repurposing, convalescent plasma therapy, and monoclonal antibody development. Among the above efforts, this review examines COVID-19 drug development along with the related and upcoming challenges.

Increasing use of embedded systems has made many improvements on hardware development for specific purpose. Hardware changes are more expensive and harder to implement rather than software changes. Developers need tools to do design and testing of new hardware. Many simulation tools have been made to mimic the hardware and allow developer to test programs on top of new hardware. Virtual Development Environment for Embedded Software (VDEES) is one of the alternatives available. It provides an open source based platform and an Integrated Development Environment (IDE) that can be used to build and testing newly made component, faster and at low-cost.
