  • CDISC (Clinical Data Interchanging Standards Consortium) standards are to support the acquisition, exchange, submission and archival of clinical trial and research data. SDTM (Study Data Tabulation Model) for Case Report Forms (CRFs) was recommended for U.S. Food and Drug Administration (FDA) regulatory submissions since 2004. Although the SDTM Implementation Guide gives a standardized and predefined collection of submission metadata 'domains' containing extensive variable collections, transforming CRFs to SDTM files for FDA submission is still a very hard and time-consuming task. For addressing this issue, we developed metadata based SDTM mapping rules. Using these mapping rules, we also developed a semi-automatic tool, named CDISC Transformer, for transforming clinical trial data to CDISC standard compliant data. The performance of CDISC Transformer with or without MDR support was evaluated using CDISC blank CRF as the 'gold standard'. Both MDR and user inquiry-supported transformation substantially improved the accuracy of our transformation rules. CDISC Transformer will greatly reduce the workloads and enhance standardized data entry and integration for clinical trial and research in various healthcare domains.

  • The $^1H$ and $^{13}C$ chemical shifts of eleven flavone derivatives were completely determined by basic 1D and 2D NMR experiments. Nineteen flavone derivatives including the above eleven derivatives were examined for anti-oxidative effects using the 1,1-diphenyl-2-picryl-hydrazyl assay and Caenorhabditis elegans. In order to understand the relationships between the structures of flavone derivatives and their anti-oxidative activities, a Comparative Molecular Field Analysis was performed.

  • High-throughput transcriptome sequencing, also known as RNA sequencing (RNA-Seq), is a standard technology for measuring gene expression with unprecedented accuracy. Numerous bioconductor packages have been developed for the statistical analysis of RNA-Seq data. However, these tools focus on specific aspects of the data analysis pipeline, and are difficult to appropriately integrate with one another due to their disparate data structures and processing methods. They also lack visualization methods to confirm the integrity of the data and the process. In this paper, we propose an R-based RNA-Seq analysis pipeline called TRAPR, an integrated tool that facilitates the statistical analysis and visualization of RNA-Seq expression data. TRAPR provides various functions for data management, the filtering of low-quality data, normalization, transformation, statistical analysis, data visualization, and result visualization that allow researchers to build customized analysis pipelines.

  • Purpose: The purpose of this study was to identify the moderating and mediating effects of self-leadership in the relationship between organizational culture and nurses' informatics competency. Methods: Participants in this study were 297 nurses from the cities of Busan and Ulsan. The scales of organizational culture, self-leadership and informatics competency for nurses were used in this study. Descriptive statistics, Pearson correlation coefficient, stepwise multiple regression were used for data analysis. Results: Nursing informatics competency of the participants was relatively low with a mean score 3.02. There were significant positive correlations between subcategories of perceived organizational culture, self-leadership and nursing informatics competency. Self-leadership was a moderator and a mediator between organizational culture and informatics competency. Conclusion: Based on the results of this study, self-leadership promotion strategies to improve nursing informatics competency are needed.

  • In this paper, we have looked at through core competences and contents of Informatics curriculum in middle school by expert questionnaire and Focus Group Interview(FGI). Among nine core competences of Informatics subject in curriculum, abstraction and automation were easily found, but creative harmony and cooperation were indirectly confirmed in the statements of teaching and assessment sections of Informatics curriculum in middle school. It was also identified that some core competency elements are redundant or hardly to found in the contents of Informatics curriculum. In addition, various opinions about Informatics curriculum have been put forward over the FGI. The results of this study will be the case that can be consulted on new revised Informatics curriculum to be developed further.
