NEW ANALYSIS OF VISUALIZATION IN EDUINFORMATICS USING A NETWORK WITH PARAMETRIC AND NONPARAMETRIC CORRELATION COEFFICIENTS WITH THRESHOLD

Eduinformatics, a new term coined by us, is a field that combines education and informatics, and novel techniques will need to be developed for this field. Earlier, we developed a new visualization method to visualize the curriculum of Kobe Tokiwa University using multidimensional scaling (MDS) and a scatter plot. In this study, our focus is on methods to analyze the relationships between answers to questions in eduinformatics questionnaires. MDS methods are very useful, but have limitations in that their results are difficult to interpret. To facilitate the interpretation of these results, we develop a new visualization method using a network with both parametric and non-parametric correlation coefficients with a threshold (VNCC). VNCC has nine steps. We apply the VNCC method to research on nursing education, and provide an example of the visualization of the result. VNCC methods will be useful in dealing with qualitative research in eduinformatics

Perioperative therapy for non-small cell lung cancer - Current status and future perspective -

　Lung cancer is the leading cause of cancer-related death. Surgery has been playing a pivotal role in the treatments with curative intent for non-small cell lung cancer (NSCLC). However, the outcome after surgery alone remains unsatisfactory. During the last two decades, several attempts have been made to improve the postoperative outcome. Metaanalysis demonstrated that adjuvant cisplatin-based chemotherapy achieved 4-5% of benefit in the 5-year survival as compared to surgery alone. Preoperative induction chemotherapy also yielded a 5% improvement of the 5-year survival rate, showing a similar efficacy with adjuvant chemotherapy. Induction chemoradiotherapy enhanced local control, whereas it was not associated with any survival benefit. Recently, the development of new drugs, such as tyrosine kinase inhibitors and immune checkpoint inhibitors, represents a major treatment advance for patients with lung cancer. Several attempts have been made to apply these drugs to perioperative treatments.　In this review, we sought to summarize the developments of perioperative therapy in the treatments of NSCLC, and discuss the future perspectives
