衣服デザインに及ぼす錯視効果に関する研究 : ツェルナー錯視の活用

In this study, it is examined whether the Zollner illusion effect is useful for apparel design, or not. Zollner illusion effect seems parallel lines to slant. Applying this effect to the apparel design, we may have the impression that it looks the straight body line to incline. As a result, we get the conclusion that the Zollner illusion effect is slightly useful for giving impression of slender waist

目的：｢見守り｣に関するモニター機器の使用によって、認知症患者の家族介護者への介護負担が、軽減されるのかを調査し、次世代型介護技術の有用性を検討することを目的とした。研究方法：MEDLINE、PsycINFO、CINAHL Plus の3つのデータベースを用いて、全年を対象に検索を行い、最終的に3件のシステマティックレビューを対象とした。結果：モニター機器が介護者の不安を軽減し、患者・家族どちらにも利益があると示した文献が2件であり、介護者の負担軽減に対して利益がなかったと示した文献が1件であった。使用されたモニター機器は位置情報を用いた機器、センサー、アラームが多数を占めており、認知症患者の安全を守ること、徘徊の検出を使用目的としていた。考察：介護負担を検討した文献が少ないことや、負担感の尺度として統一した指標を用いていないことから、結果の信頼性は、高いとは言えず、新たに評価指標を統一した研究を行う必要がある。総説Review Article

Seasonal Variation and Severity of Acute Abdomen in Japan: A Nine-Year Retrospective Analysis

The seasonal incidence of acute abdomens, such as appendicitis, is reportedly more common in summer but is reported less frequently in Asia. Additionally, seasonal variations in the severity of acute abdomens have been evaluated insufficiently. This study evaluated the seasonal variations in the incidence and severity of acute abdomens in Japan. This retrospective observational study used a multicenter database containing data from 42 acute hospitals in Japan. We included all patients diagnosed with acute appendicitis, diverticulitis, cholecystitis, and cholangitis between January 2011 and December 2019. Baseline patient data included admission date, sequential organ failure assessment score, presence of sepsis, and disseminated intravascular coagulation. We enrolled 24,708 patients with acute abdomen. Seasonal admissions for all four acute abdominal diseases were the highest in summer [acute appendicitis, (OR = 1.35; 95% CI = 1.28–1.43); diverticulitis, (OR = 1.23; 95% CI = 1.16–1.31; cholecystitis (OR = 1.23; 95% CI = 1.11–1.36); and cholangitis (OR = 1.23; 95% CI = 1.12–1.36)]. The proportion of patients with sepsis and disseminated intravascular coagulation as well as the total SOFA score for each disease, did not differ significantly across seasons. Seasonal variations in disease severity were not observed
