| Abstract | 本研究は，清田哲男の理論枠組を基盤として，教員が日常生活で出会う市井の他者との対話を通じて創造性や授業観を変容させるプロセスを明確化したものである。市井プロジェクトの質的分析により，教員は他者の生き方や姿勢から新たな価値を受け取り（市井からの享受過程），その経験を契機に教育観を再編し（教育観変容過程），さらに授業構想に具体的変化を生じさせること（授業内容関与過程）が確認された。とりわけ，制度的研修では得にくい偶発的対話や生活知の受容が，教員の創造性を喚起し，日常に根ざした学びとして機能する点が成果である。本研究は，教員自身が学ぶ創造性という新たな研究領域の基盤を形成し，美術教育における創造性育成の新たな可能性を提示した。 |

| Abstract | Tibetan thangka refers to a genre of pictorial art widely produced across the Tibetan cultural region since the 11th century. Although scroll painting is its most common form, thangkas are also created through embroidery, appliqué, and brocade weaving. The subjects depicted encompass a wide range of themes within Tibetan Buddhism and the Bön religion, including various Buddhas, bodhisattvas, deities, monks, mandalas, as well as astronomical and medical knowledge. Within Tibetan religious beliefs, thangkas are not merely visual representations; they are venerated as supports of Buddha (Tib. sku rten), understood as physical embodiments of divine presence. At the same time, the creation and veneration of thangka constitute a rich aesthetic tradition in which artists repeatedly integrate realist elements into this sacred canvas. This paper offers a micro anthropological examination (Tanaka 2005; 田中 2006) of the depiction of thangka as a practice oscillating between inscribing the canonical and drawing the real. Through critically engaging with the theory of agency of art (Gell 1998), and the analysis of writing and drawing (Ingold 2017), this study examines the dialectical relationship between rendering sacred images and depicting worldly reality, and how such practices unfold in the tension between prescriptive authority and embodied perception. |

| Title Alternative | Theoretical Consideration of Creativity in Interactive Art Appreciation and Construction of an Analytical Framework |
| FullText URL | oer_057_2_017_030.pdf |
| Author | Miyazaki, Satoru| Teramoto, Shizuka| |
| Abstract | In this study, we theoretically examined the mechanism of creativity in interactive art appreciation and presented it as an analytical framework. In interactive art appreciation, viewers engage in collaborative dialogue with the artwork and other viewers, and are influenced by the promotion of creativity and improvement of the quality of the dialogue through the intervention of facilitation. This introduces an otherness that is different from the self, which creates a deviation from existing interpretations. This discrepancy in interpretation brings about a conceptual shift in the viewer, resulting in the creation of a new theory; this newly created theory eventually becomes the existing theory, and once again a collaborative dialogue takes place, giving birth to a new theory. In this cyclical process of creativity in interactive art appreciation, knowledge is created and accumulated, and existing knowledge is creatively destroyed to reconstruct new knowledge. Learning takes place through mutual learning mediated by intrinsic motivation, and eventually learning takes place to arrive at new interpretations, although sometimes learning support is handed over from the facilitator to the viewers. For viewers whose abilities to create meaning and grasp value are underdeveloped, interactive art appreciation helps to encourage this development, and it has the potential to have a ripple effect on development not only in art but also in the broader realm of everyday knowledge outside of art. |

| Abstract | Pathogens or their components can induce long-lasting changes in the behavior of innate immune cells, a process analogous to “training” for future threats or environmental adaptation. However, such training can sometimes have unintended consequences, such as the development of autoimmunity. Systemic lupus erythematosus (SLE) is a chronic and heterogeneous autoimmune disease characterized by the production of autoantibodies and progressive organ damage. Innate immunity plays a central role in its pathogenesis, contributing through impaired clearance of apoptotic cells, excessive type I interferon production, and dysregulated formation of neutrophil extracellular traps. Recent studies have revealed that metabolites and nucleic acids derived from mitochondria, a crucial energy production site, directly regulate type I interferon and anti-inflammatory cytokine production. These insights have fueled interest in targeting metabolic pathways as a novel therapeutic approach for SLE, offering promise for improving long-term patient outcomes. |

| Abstract | The status of postpartum depression was elucidated herein with the use of the Edinburgh Postnatal Depression Scale (EPDS) in women in Shikoku, Japan who became pregnant and gave birth after undergoing infertility treatment, including assisted reproductive technology (ART). The assessment was performed during their children’s 4-month health examination. The relationships between postpartum depression and the mothers’ background factors and scores on the Big Five personality traits scale were also examined. Of the Big Five personality traits, the scores for neuroticism were significantly higher in the ART group (n=71) than in the general infertility treatment (n=118) and natural pregnancy (n=872) groups. No significant differences in EPDS scores were seen among these three groups. A logistic regression analysis showed that neuroticism was associated with an EPDS score ≧9 points, (which is suggestive of postpartum depression, ) in all groups. Moreover, although a long-standing marriage had an inhibitory effect on postpartum depression in the natural pregnancy group, no such trend was seen in the ART group, which included many women with long-standing marriages. Particularly for women who become pregnant by ART, an individualized response that pays close attention to the woman’s personality traits is needed. |

| Abstract | 私は平成10年度の前期に一般科目（一般教養科目）の「社会学」の授業を担当した。本稿では，受講学生の授業評価などにより，その授業を検討し，次の3点を明らかにした。(1)私は，映画やドキュメンタリーを上映したり「講義ノート」を配布することで，社会学の授業を理解しやすくするように努めた。また，書評レポートを学生に書かせ論文作成の基礎を学ばせようとした。学生は，これらの授業改善をかなり評価していた。それから，授業のやり方や講義内容でとりたてて問題点はなかった。(2)多くの学生は，映画を上映したとき，授業時間が延長になることに苦情を持っていた。私は学生があげた苦情を解決しようと授業中に努力したが，大部分の苦情は私の努力ではどうにもできないものであった。(3)大学の当局や事務担当者には，次の2つが望まれる。第1に， 2時限連続の授業を設けることができるようにするなど，授業の性格に応じてより柔軟に，授業を開講できるようすべきだ。もしこれが可能であれば，私の授業に対する学生の苦情はほとんどなかった。第2に，シラバスを全学部の学生に配布するとか，インターネットで誰でも簡単に閲覧できるようにすべきだ。 次に，授業の改善として，私は次の3点を提案した。(1)研究の方法を一般教育課程で学生に組織的に教えること。(2)大学の授業を他の教官に公開することによって，授業の改善に努めること。(3)教官の授業負担を軽減し，授業の充実をはかること。 |

| Abstract | 学校図書館は，学習指導要領でも触れられており，国語科との関連も深い。また先行研究では，司書教諭や学校司書との協働の必要性が訴えられている。しかしこれまでの国語教育では，どのような協働がなされていたのかという検討がなされていない。そこで，本研究では，教育雑誌の調査をもとに，国語科においては，学校図書館がどのように活用されてきたのか，司書教諭や学校司書との協働はどのような態度がとられてきたのかを明らかにすることを目的とした。調査では，図書館に言及している論文や学校図書館を活用した実践・指導例を抽出し，分析した。実践・指導例の分析からは，小・中学校の国語科において学校図書館は活用されてきた一方で，司書教諭や学校司書との協働には着目が及んでいない状況が明らかになった。また，司書教諭や学校司書に関する言及からは，人的リソースにその原因を求める思潮が窺えたものの，価値ある協働も見受けられることを指摘した。 |

| Abstract | 2022年より教養教育科目「現代と社会」において，「色」を主題にして「岡大グッズ」の提案を行う探究型授業「生活の中の創造性」を開講している。授業前後のアンケートによると，学生は「自分にとって創造性は重要」と捉え，「他者とコミュニケーションを取りながら創造的な活動をすることに興味」があり，授業後は「自分のことを創造的である」と肯定的な評価となっていた。この授業は「主体的，対話的に考え，感じ，判断する自分自身の存在を意識すること」を促す効果が大きいことが分かった。この３年間の実践は，主軸となるテーマと探究活動の内容が大学生の探究的な学びに適したものであったと考えている。 |

| Abstract | 洋画家・国吉康雄 (1889-1953) は、岡山市北区出石町に生まれ，日露戦争終結後の1906 年に労働移民として単身渡米し，アメリカの教育により画家としての才能を磨き，20 世紀前半のアメリカを代表する画家として評価される洋画家・国吉康雄（1889-1953）。本論では，その画業と作品評価について論じるわが国の研究者の記述を，作家の没後の1954 年に国立近代美術館（現国立東京近代美術館）で開催された「国吉康雄遺作展」を起点とし，20 世紀中に開催された主な展覧会と，2004 年に同じく東京国立近代美術館などで開催された「国吉康雄展」で確認した。結果，日本人による国吉作品の表現が，この1954 年時に決定づけられていることに，別の捉え方を提示されるまでに40 年の歳月を要していることが明らかとなった。 |

| Abstract | We developed a machine learning model for predicting prostate cancer (PCa) grades using radiomic features of magnetic resonance imaging. 112 patients diagnosed with PCa based on prostate biopsy between January 2014 and December 2021 were evaluated. Logistic regression was used to construct two prediction models, one using radiomic features and prostate-specific antigen (PSA) values (Radiomics model) and the other Prostate Imaging-Reporting and Data System (PI-RADS) scores and PSA values (PI-RADS model), to differentiate high-grade (Gleason score [GS] ≥ 8) from intermediate or low-grade (GS < 8) PCa. Five imaging features were selected for the Radiomics model using the Gini coefficient. Model performance was evaluated using AUC, sensitivity, and specificity. The models were compared by leave-one-out cross-validation with Ridge regularization. Furthermore, the Radiomics model was evaluated using the holdout method and represented by a nomogram. The AUC of the Radiomics and PI-RADS models differed significantly (0.799, 95% CI: 0.712-0.869; and 0.710, 95% CI: 0.617-0.792, respectively). Using holdout method, the Radiomics model yielded AUC of 0.778 (95% CI: 0.552-0.925), sensitivity of 0.769, and specificity of 0.778. It outperformed the PI-RADS model and could be useful in predicting PCa grades, potentially aiding in determining appropriate treatment approaches in PCa patients. |
