Abstract

Dynamic optical coherence tomography (DOCT) statistically analyzes fluctuations in time-sequential OCT signals, enabling label-free and three-dimensional visualization of intratissue and intracellular activities. Current DOCT methods, such as logarithmic intensity variance (LIV) and OCT correlation decay speed (OCDS) have several limitations.Namely, the DOCT values and intratissue motions are not directly related, and hence DOCT values are not interpretable in the context of the tissue motility. We introduce a new DOCT algorithm that provides more direct interpretation of DOCT in the contexts of dynamic scatterer ratio and scatterer speed in the tissue.The detailed properties of the new and conventional DOCT methods are investigated by numerical simulations, and the experimental validation with in vitro and ex vivo samples demonstrates the feasibility of the new method.

Abstract

Wedemonstratedeep-learningneuralnetwork(NN)-baseddynamicopticalcoherence tomography (DOCT), which generates high-quality logarithmic-intensity-variance (LIV) DOCT images from only four OCT frames. The NN model is trained for tumor spheroid samples using a customized loss function: the weighted mean absolute error. This loss function enables highly accurate LIV image generation. The fidelity of the generated LIV images to the ground truth LIV images generated using 32 OCT frames is examined via subjective image observation and statistical analysis of image-based metrics. Fast volumetric DOCT imaging with an acquisition time of 6.55 s/volume is demonstrated using this NN-based method.

Abstract

本稿は、小学校で日本語指導を担当した経験を持つ２名の教員を対象として、実践的知識とその構造を明らかにすることを目的としたものである。調査方法としてPAC 分析を使用し、個人内の態度やイメージの構造を捉え、質的に分析することを試みた。また、インタビュー調査を実施して、日本語指導の経験が、現在の実践にどのように影響しているかも質問した。分析の結果、２名に共通する実践的知識として「実践の根幹にある信念」、「異なる価値観や考え方の受け入れにくさに起因する葛藤」、「児童のことばの成長を支援する実践の工夫」が明らかになり、その構造が示された。また、日本語指導の経験を通じて、２名に子どもを多角的に把握する視点が生成されたこともわかった。

Abstract

平成26年４月から小中学校において日本語指導が必要な児童生徒を対象に「特別の教育課程」を編\n成・実施することが可能になった。今後は、教員が児童生徒の個別の指導計画を作成し、ことばの発\n達段階に応じた指導・支援を行うことが求められる。群馬県伊勢崎市では「特別の教育課程」の実施\nに先立ち、市の教育研究所内に教員６名の日本語教育研究班が組織され、日本語指導の充実のための\n実践研究が行われている。日本語教育研究班では日本語能力測定に関する先行研究の知見を参考に、\n子どものことばの発達の様子を見取る共通指標「日本語ステップ」を開発した。これは児童生徒の日\n本語指導に関わる複数の指導者が子どものことばの発達の様子を観察・把握し、個別の指導計画につ\nいて話し合うためのツールとして使用するものである。本稿では、日本語ステップの開発目的とその\n特徴３点、および今後の活用の可能性について述べる。

Abstract

本研究では、小学校で日本語の取り出し指導を担当した教員１名を対象に PAC分析調査を実施し、教員の日本語指導のイメージや認識にどのような変化が生じたかについて考察した。調査は、対象の教員が日本語指導を始めて４ヶ月経過した時点と１年を経た時点の２回実施して比較・分析した。その結果、以下の二点に関して教員の意識に変容が認められた。（１）児童との関係性構築の方法が「教員側から積極的に働きかけをすること」から「児童の背景や情意面を尊重しながら寄り添うこと」へと変化した。（２）教員が児童とのコミュニケーションの困難さを感じることが減少し、児童の母語の発達の大切さや外国人児童が日本語を学ぶ意義について言及するようになるなど、ことばに対する意識が変化した。日本語指導の経験を通して、教員の児童を捉える視点に変容が見られ、児童の言語や文化背景の多様性を意識するようになったことが示された。, Recently, Japanese language education to foreign children in schools has become a nationwide educational issue. To consider the further substantiality of Japanese language education, especially for foreign school children, it is important to clarify the teachers’viewpoints towards language education, and to utilize the knowledge they acquired through their practice. The purpose of this paper is to examine how cognitive change occurs in a teacher who was in charge of Japanese as a second language (JSL) class for the first time at a primary school. The teacher was interviewed twice, once in August 2013 and once in March 2014.The PAC (Personal Attitude Construct) Analysis was adopted for the interview analysis. The objective was to clarify which point the teacher’s attitude toward teaching JSL changed during a one-year course. From the comparison of the results of two the interviews, two significant cognitive changes were shown: (1) The teacher came to recognize that it is important to understand foreign children’s backgrounds and their viewpoints. (2) The teacher became to value the importance of multi-language education for foreign children. Thus, the results indicated that the teacher’s cognition of the importance of the children’s first language and cultural backgrounds changed.

Abstract

Background: Early worsening heart failure (WHF), defined as worsening of symptoms and signs of heart failure requiring intensification of medical or mechanical therapy during an admission for acute decompensated heart failure (ADHF), has recently been recognized as a risk of morbidity or mortality after the discharge. Although echocardiographic parameters of left ventricular (LV) output has been shown to be associated with long-term outcome in heart failure patients, its predictive value for early WHF has not been elucidated. Methods: Prospect trial to Elucidate the utility of EchocarDiography-based Cardiac output in acute heart failure (PREDICT) is a multicenter, nonrandomized, prospective observational study to test the predictive value of echocardiographic LV output parameters for early WHF in ADHF patients. We will enroll patients admitted to 16 participating hospitals due to ADHF who did not receive positive inotropic agents as an initial therapy. Primary outcome will be set at early WHF defined as need for initiation of positive inotropic agents within 7 days after the admission. Predictive accuracy will be compared between Doppler echocardiographic LV output (stroke distance, stroke volume index, and cardiac index) and low perfusion findings assessed by physical examination. Results: N/A. Conclusions: The PREDICT is expected to provide large data set to test the predictive value of echocardiographic LV output for early WHF in ADHF patients. [ABSTRACT FROM AUTHOR]

Abstract

日本語指導が必要な児童生徒が抱える教育的課題は多岐にわたるため、その対応には現場の教員の視点を取り入れることが必要であると考えられる。本研究では、小学校で日本語指導が必要な児童を担当する教員のビリーフを探求することを目的に、インタビュー調査を行った。5 名の教員に対する調査の結果、共通して現れたビリーフは①学習に関する指導、②生活・学習態度に関する指導、③日本語教室の役割、④担任教員との連携という4つの領域に分類された。このビリーフには、教員が学校生活での行動や学習態度などを含め、広い視点で児童を捉えようとする傾向が見られた。また、教員は言語知識や教科内容に関する知識の習得のみを目的として指導するのではなく、児童が集団内で、その一員として活動に参加し、他者とのつながりから学ぶという点を重視していることが明らかになった。

Abstract

1)単変量解析では, score値, stage, T分類, M分類, 腫瘍マーカー, 治療法が予後に重要であった.2)多変量解析ではscore値, M分類, AIP値が予後に重要であった.特にGleason分類は最も予後に影響しており, T分類, stage ACP PAPは予後因子とはならなかった.3) 3年目の予後ではscore値以外に転移の有無, 5年目の予後では年齢が重要な因子であった, A multivariate statistical analysis of 9 potential prognostic factors was made, using data gathered on 107 patients admitted between 1975 and 1987. After each variable was assessed separately for its prognostic importance by means of univariate analysis, a multivariate analysis using Cox's proportional hazards regression model and multivariate logistic model was done. These tests identified Gleason's score as the most important factor for all patients followed by M category and alkaline phosphatase (ALP), while Gleason's score alkaline phosphatase and age at diagnosis were most important for stage D patients. For short-term survival, the significant prognostic factors were Gleason's score and M category while for long term survival they were Gleason's score and age. T. category, stage, acid phosphatase, prostatic acid phosphatase, and treatment were found to be significantly related to survival time when examined individually; they were not found to be significant in the multivariate analysis.

The patient (female) had progressive renal dysfunction, hypertension which was difficult to control, and massive gastrointestinal bleeding. An angiotensin converting enzyme inhibitor (enalapril) could not control her hypertension. Only intravenous nicardipine had a slight effect on her hypertension. Hemodialysis and plasma exchange, did not reverse the renal crisis, and the patient died. Microscopic examination of her kidney showed thickening of the capillary walls and mild nephrosclerosis.

Abstract

Recently it has become clear that venous impotents account for a high percentage of all impotents. In venous impotents a decrease in outflow resistance is seen. We have aggressively performed operations on venous impotents to produce artificial outflow resistance. In this study, we performed ligations of the crura penis in 6 venous impotents. Five patients recovered from erectile dysfunction and 1 patient showed papaverine-induced full erection. There were few severe complications and the duration of operation was very short. This operation is thought to be a simple and effective treatment for venous impotence.
