Abstract To evaluate the effectiveness of postoperative irradiation (POI) for patients with cN0 early breast cancer, we retrospectively analyzed the cases of 650 consecutive breast cancer patients who underwent sentinel lymph node (SLN)-guided surgery (2005-2022) at our hospital. In this cohort, 53% (278/521) of the patients who underwent breast conservative surgery (BCS) and 96% (124/129) of those treated with mastectomy did not receive POI. The patients who underwent BCS were treated with POI using opposing tangential field irradiation. A false negative (FN) SLN was retrospectively defined as a negative metastasis in SLN plus positive recurrence in the axillary lymph nodes. Recurrence was detected in 83 patients. A logistic regression analysis revealed that the nuclear grade (odds ratio [OR] 1.69), POI (OR 0.41), and postoperative hormone therapy (OR 0.40) were each significantly related to recurrence. The 26.1% (12/46) FN rate of the non-POI patients decreased to 5.8% (1/17) compared to those treated with POI. The rate of axillary recurrence was significantly lower in the POI group (0.4%) versus the non-POI group (2.7%) (p=0.0355). The rate of locoregional recurrence was also significantly lower in the POI group (2.0%) versus the non-POI group (13.4%) (p<0.0001). No significant difference was observed in the rate of distant recurrence between the POI (4.0%) and non-POI (3.3%) (p=0.831) groups. These results indicated that the postoperative opposing tangential field irradiation of conserved breast tissue inhibited recurrence in the axillary lymph nodes.

Abstract School teachers are subject to both physical and mental health problems. We examined cross-sectional relationships between work engagement and major health outcomes among junior and senior high school teachers in Japan via a nationwide survey in 2019-2020. A total of 3,160 respondents were included in the analyses (19.9% response rate). Work engagement was assessed with the Utrecht Work Engagement Scale-9 (UWES-9), and we thus divided the teachers into quartiles according to their UWES-9 scores. Based on validated questionnaires, we assessed insomnia, psychological distress, and neck pain as health outcomes. A binomial logistic regression adjusted for age, gender, school type, teacher’s roles, involvement in club activities, division of duties, employment status, and whether they lived with family demonstrated that the teachers with lower UWES-9 scores had higher burdens of insomnia, psychological distress, and neck pain (odds ratios [95% confidence intervals] in 4th vs. 1st quartile, 2.92 (2.34-3.65), 3.70 (2.81-4.88), and 2.12 (1.68-2.68), respectively; all trend p<0.001). There were no significant differences in these associations between full-time and part-time teachers. Our findings indicate that low work engagement may contribute to physical and mental health issues among junior and senior high school teachers, thus providing insights for preventing health problems in this profession.

Abstract  本研究の目的は,知的障害特別支援学校高等部に在籍する生徒の行動問題に着目し,学校現場で教員が適切に対応する際の枠組みを明らかにすることである。その方法として,生徒指導上の課題を理由とする教育困難期を乗り越えたA 知的障害特別支援学校高等部に所属していた経験豊富な教員4名に面接調査を実施し,M-GTA の手法を援用した質的分析を行った。その結果,【安心感を生む個との関係づくり】と【対応方法の共有と統一化を目指す】関係性がコア・カテゴリーと位置づき,16の諸概念を生成した。行動問題に直面した教員は,生徒に対しては【安心感を生む個との関係づくり】を対応の軸とし,その背後では学校として【対応方法の共有と統一化を目指す】ための動きをしていた。最後に,本研究で明らかとなった対応の枠組みについて考察した観点から,個別の時間を含む階層性のある包括的な支援システムを一つの提案とした。

Abstract 岡山大学では学術英語の語彙力を伸ばすための自習教材として、「きびたんご」を開発し学生に提供している。2019年から開発のためのプロジェクトを開始し、学術雑誌から頻出単語を収集し1500語のリストを作成した。単語には意味・発音などの基礎情報以外に、プロジェクトメンバーによる解説や実際にどのように学術論文中に使用されているかの実例を付している。学生への提供は2022年度からで、登録した学生にメールで一日一単語配信し、専用ウェッブサイトで学習させるというシステムである。利用者も順調に増えている。開発開始から5年、提供から2年経過し、単語リストのアップデートや提供方法・システムの改善など課題も明らかになっている。

Abstract We retrospectively analyzed the safety of the use of articaine, an amide-type local anesthetic, in Japanese dental patients (n=300) treated in Thailand in 2015-2017. The dosage, adverse events (AEs) caused by local anesthesia, and treatment efficacy were examined. Articaine, which is safe for patients with liver impairments due to its unique metabolism, has not been thoroughly tested in Japan for doses above 5.1 mL. Eighty of the present patients had undergone root canal treatment (RCT), 71 underwent tooth extraction, and 149 underwent implant-related surgery. More than three articaine cartridges were used in 41 patients, and no AEs occurred in these cases. The only AE occurred in a 52-year-old woman who was treated with three cartridges and presented with what appeared to be hyperventilation syndrome; she later recovered and received her dental treatment as scheduled. Most treatments were completed with three or fewer cartridges, suggesting that this number is generally sufficient. Our findings, particularly the low AE risk even with doses exceeding three cartridges, support the potential applicability of the overseas recommended maximum dose of articaine (7 mg/kg) in Japanese patients. This conclusion is significant for advancing dental anesthetic practices and ensuring patient safety and treatment efficacy in Japan.

Title Alternative A brief study on the gun-teki sekai (social conditions in the district) of Asuwa district in Echizen province
JaLCDOI 10.18926/67957
FullText URL jdc_004_080.pdf
Author WATANABE, Atsunori|
Abstract  Often discussed in recent years, the term gun-teki sekai refers to the social conditions of a district. In ancient Japanese local communities, there existed complex webs of historical rule and intertwined relationships between local clans that date back to before the establishment of the Ritsuryō system. Gun-teki sekai is a term that refers to the reality of the control of the provincial and district systems, in which multiple powerful clans served as gunji , district governors under the Ritsuryō system. Each gunji organized smaller clans below them to carry out administrative duties based on such relationships. Recent research is beginning to reveal the multipolar structure of the gun-teki sekai .
 In this study, the author examines the gun-teki sekai through an analysis of the Asuwa district in Echizen province, which is rich in historical materials. As a result, the following four points became clear. First, it is highly likely that the powerful clans who served as district governors in the mid-Nara period were traditional clans with roots in the eastern part of the district. Second, the powerful clans who served as district deputy governors may have been an emerging power. Third, from an archaeological perspective, the eastern part of the district is the traditional area, while the dominance of the western part of the district developed after the establishment of the Ritsuryō system. Fourth, in terms of clan distribution, the clans who served as district governors were distributed over the widest area, followed by those who served as district deputy governors.

Title Alternative What is education for sustainable development?: From the perspective of international legal history

Author KAWAKAMI, Yoko|
Abstract Throughout the history of international law, sustainable development has always been acknowledged as a global responsibility. In recent years, as global environmental concerns have escalated, this responsibility has become increasingly crucial. To fulfil this mandate, education policies must transcend national boundaries. Specifically, in light of pressing global environmental issues such as climate change, education on sustainable development is pivotal for the well-being of future generations. To delve deeper into this significance, the author examines the emergence of ESD (Education for Sustainable Development), its accomplishments, and the challenges the world is currently grappling with.
