野外学習においてドローンを利用することは,学習者の等身大の視点に,ドローン画像による上空からのリアルタイムの視点を加えることを可能にする.等身大の視点では見えなかったり,空間的配置がわかりにくいものでも,ドローンによる視点を加えることによって理解を促進する効果が期待できるのである.そこで筆者らは治水学習の一環として,ドローンを使用した野外学習教材の開発を試みた.三重県安濃川に残る伝統的な治水手法である越流堤と霞堤を対象とした野外学習においてドローンを使用し,ドローンからコントローラーに送信される画像を教師のフェイスブックに転送し,ポケットWi-Fiを通じて児童のiPadに配信し,それを教師が説明するという構成の教材である.評価は児童の理解度の自己評価,ドローンで学習したことに対する児童の評価,授業後の振り返りの分析により行った.その結果,ドローンを利用した野外学習教材は治水手法の理解を促す上で一定の効果があったと判断できる.

Objective: Determining the course of occluded vessels in advance will increase the success rate and safety of mechanical thrombectomy (MT). Herein, we evaluate the usefulness of MR fusion images created via 3D T2-weighted sampling perfection with application-optimized contrasts using different flip angle evolutions (T2-SPACE) and 3D time-of-flight (TOF)-MRA for visualization of occluded vessels in patients with acute ischemic stroke (AIS) before MT.Methods: We enrolled 26 patients with AIS caused by intracranial large vessel occlusion who presented at our hospital and underwent MRI with fusion images unaffected by motion artifacts in our study. All patients underwent T2-SPACE and TOF-MRA followed by MT. We created fusion images of the T2-SPACE and TOF-MRA by combining a translucent image of the occluded artery produced by the flow void effect in T2-SPACE with the same vessel in a TOF-MRA image. Fusion images were compared with post-recanalization angiography and post-recanalization MRA, respectively, and the degree of agreement in depiction of M1 runs and M2 branching beyond the occlusion on three levels was assessed. Imaging evaluations were performed independently by two endovascular specialists.Results: The interobserver agreement of the MRI findings about the concordance of the occluded vessel’s run was excellent (kappa was 0.87 [confidence interval: 0.61–1.12]). In all, 21 patients (80.8%) had excellent imaging, four (15.4%) had fair imaging, and one (3.8%) had a divided opinion of the rating between excellent and fair imaging. No cases were judged to be poorly drawn. Even if there was a localized signal loss, its distal portion could be delineated, so it did not affect the estimation of the entire vessel run, and we found that the anatomical structures of the occluded vessels were distinctly visible in the fusion images.Conclusion: We demonstrated that MR fusion images derived using T2-SPACE and MRA methodologies could determine the courses of occluded vessels prior to MT performed for AIS. Fusion MR imaging may have potential as a preoperative test for ensuring effective and safe MT procedures.

Objective: The Mo.Ma Ultra is an embolic protection device used in carotid artery stenting (CAS). In cases of left internal carotid artery stenosis (ICS) in which the common carotid artery (CCA) branches off the aortic arch at a steep angle, insertion of the Mo.Ma Ultra into the CCA is sometimes difficult. We introduce a “buddy catheter technique” that helps guide the Mo.Ma Ultra into the CCA, with an additional 4 Fr catheter into the external carotid artery.Case Presentation: An 84-year-old man with left ICS whose CCA also branched off the aortic arch at a steep angle also underwent CAS. The “buddy catheter technique” was used, and the Mo.Ma Ultra was inserted smoothly. The buddy catheter technique displaces the left CCA upward. Displacement straightens the vessels anatomically, and the ledge effect can be prevented by aligning the course of the vessels with the wire. Nevertheless, this technique requires bilateral femoral puncture, and so, complications can occur.Conclusion: The buddy catheter technique may be considered in cases in which the left CCA branches off the aortic arch at a steep angle.

This paper investigates the issues of students' ability to learn and the necessity for educational knowledge from 1957 to 1969, using the specific example of English teaching. With a special focus on discourse in the movement of the Japan Teachers Union, this paper examines the manner in which teachers dealt with these issues by constructing their own discourses and practices.Several points emerge from the analysis of educational movement discourses in English teaching. People, including educational participants, initially tended to believe that learning English served no purpose, and students found it extremely difficult to master the language. In the movement of the Japan Teachers Union, however, teachers indicated that the aim of learning English was not only to master the language but also to build the learner's character; therefore, it would be useful for all students to learn English. This idea is embodied in the “Four Goals, ” which seek the solidarity of nations and the deepening of students' understanding of their own languages rather than the acquisition of English. Consequently, two concrete attempts to attain these goals are notable. The first is independent practices by teachers to concretize the “Four Goals” that help build character. The second attempt is the discourse to redefine the ability to measure achievement in independent practice. The discourse on ability demonstrates that “true ability” is best measured not by the achievement tests given by the Ministry of Education but rather by a “zest for living.”In summary, focusing on the building of students' character rather than the mastery of learning materials led to a “solution” of the issues involving students' ability to learn and the need for educational knowledge in the discursive space alone. This form of “solution, ” through the analysis of discourse within the educational movement, is described as the “Japanese educational structure from the perspective of student's ability to learn.”

Patients with Parkinson disease present with a variety of symptoms as well as the so-called 4 classic symptoms : tremor, muscle rigidity, akinesia, and postural instability. To treat this disease, the best combination of various antiparkinsonism drugs, deep brain stimulation, and rehabilitation should be determined and administered. Muscular training in rehabilitation for patients should place great importance on some especially vulnerable muscles including the truncal muscles, extensor muscles for hip and knee joints, and dorsiflexor muscles for ankle joints. Shifting the center of gravity and using rhythmic movements are important factors in getting the patient standing and walking. Training using visual and auditory cues and music is effective in Parkinson disease. Speech therapy using weighted noise is also available. In rehabilitation we have to pay attention to cognitive function and psychiatric symptoms in patients including depression, anhedonia, hallucination, delusion, dopamine dysregulation syndrome, and impulse control disorder. What priority should be set for rehabilitation differs according to the stages of disease. Utmost efforts must be made for patients in the advanced stage of Parkinson disease to prevent them from being bedridden, tube-fed, and demented. Medical staff must be creative in coming up with new ideas to assist such patients in sitting comfortably on chairs for long periods and in eating by mouth safely.

鍬形蕙斎(北尾政美)画、素外撰の絵俳書。色摺り。享和2年(1802)初秋、江戸・須原屋市兵衛板、大本1冊。享和2年夏の素外の序に「爰に鱗介の生写あり、書林申椒堂梓に上せむことを思ひ、予に社中の発句を乞、将題を需む」とあるように、魚貝の図譜に、素外撰の発句を添えたもの。題名の由来は、同序に「今蕙子精神をもとゝす、これを滑稽の淵に踊らせ、又諧語の浪に乗すれは、頓て龍闕にも朝せむ勢ひ見えたり、よて龍乃宮津子と号し与え侍るなり」とあり、蕙斎の精神を基とした描図に俳諧の滑稽を掛け合わせて、生動する魚貝類によって、竜宮の朝政を再現させるという意により命名したという。本草図譜のような精密な線描に、淡泊な色合いの重ね摺り、背から腹にかけての拭きぼかしなど、微妙な色調による表現が見どころ。巻末に、素外ほかの発句だけの丁を配する。勝間竜水の『海幸』の影響が感じられる。(鈴木淳)(2017.2)
