この論文では、有限体上の符号理論を環上の符号理論へ拡張する方法を考察する。最初に、有限体の拡張とし て有限可換QF 環を考え、線形符号の巡回性を調べる。巡回符号の自然な拡張として、多重巡回符号と逐次符号を定 義し、有限可換QF 環上の双対性を調べる。また、有限可換QF 環上の自由符号において、可逆な定数項をもつ単項 多重巡回符号の特徴づけを行う。最後に、有限可換QF 環上の線形符号を有限非可換環上へ拡張することを考え、今 後の研究の方向性をまとめる。In this paper we generalize coding theory over finite fields to finite rings. First, we consider finite commutative QF rings instead of finite fields, and we study cyclicity of linear codes. We define polycyclic codes and sequential codes, natural generalization of cyclic codes, and study duality of these codes over finite commutative QF rings. Next, we characterized the family of principal polycyclic codes with invertible constant terms over finite commutative QF rings. Finally, we generalize coding theory over finite commutative QF rings to finite noncommutative rings, and we show results and problems of the neighbourhood last

本研究の目的は等長変換を用いた教材を通して、高校生に数学への興味・関心をもたせることである。旧課程 における行列には、それまでの高校生が習わない新しい概念がいくつも含まれている。例えば、非可換性、べき零性、 線形性などである。これらの豊富な内容を高校生に有効に伝える1 つの手段として、筆者が等長変換を題材にして作 成した教材を考察する。教材の特徴として、解答が多彩なことが挙げられる。次に、筆者の以前の勤務校において授 業実践を行った結果を報告する。新課程においては行列が姿を消したが、行列の重要性を本論文において改めて探り たい。The purpose of this study is to bring up interest to mathematics for high school students. A new concept is included in the field of the matrices of high school mathematics. For example, noncommutativity, nilpotency, linearity. These properties are surprising things for high school students. We took up the isometric transformations for the subject since it contained very interesting contents. We developed the teaching materials of isometric transformations. It is creation and multifaced answers to be important by learning of high school mathematics. We taught it using the teaching materials which we developed. The method of the investigation is the questionary survey

本論文においては、小学校教員養成における算数科教育について考察する。昨年度、著者が科目"算数"の標準モデルをもとに構成した授業内容を改良し、再提出する。授業方法としては、昨年同様、学生の集中力の観点から授業時間を細かく分割する手法を用いた。具体的には、説明、例題演習、答え合わせなどに授業を分けた。また、著者が勤務する大学において、これらの方法で実践した内容を報告し、アンケート結果を考察する。最後に、今後の成果と課題についてまとめる。This paper focuses on mathematics education in primary schools, and implications for primary school teacher training. We describe the contents of a typical lesson devised using a standard model of arithmetic. The teaching method involved a technique of carefully dividing a school hour into smaller segments based on concentration levels of the students. Specifically, an hour was divided into set time periods for explanation, practice, and checking. The paper describes the way in which this approach was conveyed to primary school teachers in training at the university where the author works. Results from a questionnaire given to the teachers are described. Future studies will need to investigate the effectiveness of this approach more objectively, as well as consider the context in which the teaching is carried out

教員養成におけるアドラー心理学に基づくアクティブ・ラーニング導入の試み

大学における教員養成においては知識の注入だけではなく，主体性や協働性などを意識した指導が求められている。一斉型の授業形態だけではなく，アクティブ・ラーニング等を取り入れた授業である。一方，教育とアドラー心理学の親和性がよいことは分かっており，教員養成に効果的に取り入れられることが望まれる。アドラー心理学の理論や実践においては，共同体感覚や他者への貢献，勇気づけなどが特徴であり，これらは教育においても重要な観点だからである。本研究においては，教員養成における理数系科目やゼミに対するアドラー心理学導入の意義を理論や実践から明らかにすることを目的としている。前半において教育へのアドラー心理学導入の意義を考察し，後半では共同体感覚を育てる場の実現に向けた提言を行い，授業実践の報告を行う。最後に，今後の成果と課題についてまとめる

せん妄の遷延化に関連する因子についての後方視研究

Background: It has been reported that delirium causes various problems. Many researchers have reported the risk factors associated with the onset of delirium; however, there are few reports focused on persistent delirium. This study aimed to identify the risk factors associated with persistent delirium. Methods: A total of 573 patients hospitalised in Nara Prefecture General Medical Centre from October 2014 through September 2017 who were referred to the psychiatry consultation service were included in this study. Persistent delirium was defined as delirium lasting for 14 days or more. A retrospective study was carried out based on the patients' records. The relationship between various background factors and persistent delirium was statistically analysed. Results: Of the 573 hospitalised patients, 295 were diagnosed as having delirium. Forty-six patients with persistent delirium and 181 patients with nonpersistent delirium were included in this study. Multivariable logistic regression analyses revealed that male gender, opioid analgesics use, non-opioid analgesics use, and low serum sodium were significantly and independently associated with persistent delirium. Ramelteon or trazodone was used significantly more in persistent delirium, although each use was not significant. Conclusion: This is the first study to reveal that male gender and use of analgesics were associated with persistent delirium in general hospital. However, as this is a case-control study and may contain bias, future cohort studies and intervention studies are needed. It is also necessary to investigate the relevance of the 'degree of pain' behind the use of analgesics.博士（医学）・乙第1516号・令和3年12月21日© 2021 Japanese Psychogeriatric Society.This is the peer reviewed version of the following article: [https://onlinelibrary.wiley.com/doi/10.1111/psyg.12655], which has been published in final form at [https://doi.org/10.1111/psyg.12655].

Patient's Self-monitoring of Transurethral Surgical Images Using a Head-mounted Display

AbstractWe present an application of head-mounted display (HMD) to patient's self-monitoring of transurethral resection of bladder tumor (TURB). Six patients wore the HMD as an imaging monitor to view the operation in real-time during their TURB. Following the operation, the patients completed a questionnaire that evaluates understanding of the state of their disease and satisfaction with the HMD. As a result, monitoring the operation in real time through the HMD helped to increase patients' understanding of the state of their disease and satisfaction. For selected patients, the use of HMD could help to increase the patient's understanding of their disease
