書籍をデータ化する際に様々なスキャナやスマートフォンのカメラを用いて撮影した画像には湾曲するひずみが確認されている.これは綴じている文書に対し上部から撮影を行った場合に確認される現象で,綴じた辺に向け湾曲したひずみが生じる.このひずみを補正する方法は種々存在するが,一つのアルゴリズムでさまざまなひずみを補正する方法は存在しない.本論文では最小2乗法とAICによる次数選択を行い,文書画像のひずみ形状を限定しない補正手法を提案する.結果としてOCR機能による認識実験において,提案手法は93%の認識成功率を示すことを確認した.

現行法上,NPO法人に対しては「政治活動」を制限する規定が置かれ,公益社団法人については公益性審査に際して「政治活動」を行う団体であるかが審査されている。これら団体による「政治活動」の制限に対して,憲法学はほとんど関心を示してこなかった。その最大の理由は,法人格の取得が一般社団法人制度によって担保されているため,何らかの利益を伴う法人格については,それを付与しなくとも憲法上の問題とはならないという思考にあるように見受けられる。しかし,他の法人格と別異取扱いをする合理的理由がなければ憲法14条1項の問題になりうるし,それら法人による政治活動を広く制限することは憲法21条1項で保障される結社の自由の客観的・社会的価値を損なわせることになる。そのような視点から,憲法上の問題として検討していくことが求められる。

Taste perception is determined by multiple factors. The sensation of taste includes gustation, olfaction, other organ functions and interactions among them, and not only such sensory information but also physiological, social and cultural contexts. Recent findings on the response of taste receptors to high salt stimuli might provide psychological insight on strong salty taste as a multisensory perception. Many studies have shown that subjective taste intensity is enhanced by odors that are congruent. Some reports have suggested that subjective taste is more strongly enhanced by retronasal than by orthonasal odor detection. Differences between the two routes include the direction of airflow accompanying breathing. Thus, the kinetic sensation of breathing might be a determining factor for odor-induced taste enhancement. As well as effects of multisensory perception on taste, preference and palatability on food are not just determined by multisensory perception, but other multiple factors such as physical condition, cultural difference, learning, and the effect of heuristics on risk perception.

Background: Atrial fibrillation (AF) patients often have concomitant coronary artery disease (CAD); however, there are little data on clinical characteristics and outcomes of such patients in daily clinical practice in Japan.Methods and Results: The Fushimi AF Registry is a community-based prospective survey of AF patients in Fushimi-ku, Kyoto, Japan. Follow-up data were available for 4,464 patients, and the median follow up was 5.1 (interquartile range: 2.3–8.0) years. History of CAD was present in 647 patients (14%); of those patients, 267 (41%) had history of myocardial infarction (MI). Patients with CAD were older and had more comorbidities than those without CAD. The crude incidences (% per patient-year) of cardiovascular events were significantly higher in patients with CAD than those without CAD (cardiac death: 1.8 vs. 0.7, stroke or systemic embolism [SE]: 2.9 vs. 2.1, MI: 0.6 vs. 0.1, composite of those events: 5.1 vs. 2.8, respectively, all log-rank P<0.01). After multivariate adjustment, concomitant CAD was associated with incidence of cardiac events, and history of MI was associated with incidence of MI; however, neither history of CAD nor MI was associated with the incidence of stroke/SE.Conclusions: In Japanese AF patients, concomitant CAD was associated with higher prevalences of major co-morbidities and higher incidences of cardiovascular events; however, history of CAD was not associated with the incidence of stroke/SE.

A 70-year-old man was diagnosed with hepatocellular carcinoma (HCC) with portal vein invasion and lung metastases, for which atezolizumab plus bevacizumab (ATZ/BEV) was initiated. After two months, computed tomography revealed tumor growth accompanied by ascites, right ventricular invasion, exacerbation of the lung metastases, and main portal vein invasion. However, continuation of ATZ/BEV caused remarkable size reductions in all lesions, finally resulting in the disappearance of the vascular invasion and lung metastases after nine cycles of treatment. The tumor growth was considered to reflect pseudoprogression, which is difficult to distinguish from hyperprogression. We herein report a remarkable HCC case of pseudoprogression on ATZ/BEV.
