本研究は意味判断課題を用いて, 同音異義語と形態類似性の干渉の有無から日本語母語話者と日本語学習者の漢字熟語の処理経路を検討した。その結果, 日本語母語話者では, 同音異義語の干渉は形態類似性のある条件にのみ生じたので, 漢字熟語の意味アクセスにおける形態情報及び音韻情報の重要性が示されている。一方, 日本語学習者では, 韓国人日本語学習者は形態類似性による干渉のみ示され, 形態情報に依存する意味アクセスの可能性が大きいと示唆されている。他方, 非漢字圏日本語学習者は同音異義語及び形態類似性の干渉が生じたことが明らかになり, 音韻処理を媒介して意味アクセスすることが示されている。これらの結果は, 日本語学習者は漢字既有知識の有無によって漢字熟語の処理経路が異なる可能性を示すものである。

:国境離島である対馬は、大陸の影響を色濃く受けた極めて独特な生態系を有している。島の9 割を占める山林は、その大部分が二次林であり、炭焼きや焼き畑といった人々の暮らしによって形成された里山環境が広がっている。一方で、信仰の力によって開発から守られてきた原生林も存在している。しかし対馬では、急速な過疎高齢化によって里山の劣化が進み、原生林においても獣害や悪質な生物採取により貴重な動植物の生息環境が破壊されている。里山を象徴する生物であるツシマヤマネコも年々数を減らし、絶滅危惧種IA 類に指定されている。そのような背景があって、対馬では、原生的な自然と里山環境とを同時に保全するための仕組みづくりが喫緊の課題であった。市民レベルでは、野焼きの復活や環境配慮型農業の導入など、ツシマヤマネコの保全を銘打ったさまざまな活動が行われている。しかし、これらの活動が継続されるためには、制度的な仕掛けが必要である。ユネスコエコパークの枠組みは、原生的な自然と里山環境とを、エコツーリズムや教育、あるいは経済的な仕組みによって保全する一助となるものであり、まさにこの目的に合致するものだった。本稿では、対馬の自然の特徴を整理したうえで、その保全活動の促進や継続に関してユネスコエコパークが果たす役割について考察したい。

To clarify the spatial structure of number density distribution of bubbles in stout beer poured into a container, we investigated local time development of the void fraction and velocity of bubbles. The propagation velocity of the texture, i.e. the number density distribution, appearing near the inclined wall of the container is measured by the images analysis. We measured the local void fraction using brightness of images while the velocity of bubbles by means of Particle Tracking Velocimetry. As the result of measurements, we found the local void fraction and the bubbles advection velocity increase and decrease repeatedly with a time delay. We conclude the pattern of the number density distribution of bubbles is composed of fluid blobs which contain less bubbles; extruding and suction flows respectively toward and from the interior of the container form respectively in front and back of the blobs.

Background:Little is known about factors associated with elevated N-terminal pro B-type natriuretic peptide (NT-proBNP) at the convalescent stage and their effects on 1-year outcomes in patients with heart failure with preserved ejection fraction (HFpEF).Methods and Results:This study included 469 patients with HFpEF. Elevated NT-proBNP was defined as the highest quartile. The first 3 quartiles (Q1–Q3) were combined together for comparison with the fourth quartile (Q4). Median NT-proBNP concentrations in Q1–Q3 and Q4 were 669 and 3,504 pg/mL, respectively. Multivariate logistic regression analysis revealed that low albumin (odds ratio [OR] 2.44; 95% confidence interval [CI] 1.35–4.39; P=0.003), low estimated glomerular filtration rate (OR 5.83; 95% CI 3.46–9.83; P<0.001), high C-reactive protein (OR 2.09; 95% CI 1.21–3.63; P=0.009), and atrial fibrillation at discharge (OR 2.33; 95% CI 1.40–3.89; P=0.001) were associated with elevated NT-proBNP. Cumulative rates of all-cause mortality and heart failure rehospitalization were significantly higher in Q4 than in Q1–Q3 (P=0.001 and P<0.001, respectively). Incidence and hazard ratios of these adverse events increased when the number of associated factors for elevated NT-proBNP clustered together (P<0.001 and P=0.002, respectively).Conclusions:In addition to atrial fibrillation, extracardiac factors (malnutrition, renal impairment and inflammation) were associated with elevated NT-proBNP at the convalescent stage, and led to poor prognosis in patients with HFpEF.

Conventional image display devices and image acquisition devices consist of regularly located pixels. The pixels are located in a matrix for ease of implementation. Matrix placement of pixels intrinsically has directional singularity in the representation of images. The clarity of represented images is significantly dependent on the directions that objects in the image, such as lines, are facing. For example, horizontal lines are perfectly represented by matrix pixels, while the slanted lines have the jagged edges.We developed a pseudorandom pixel placement architecture that has no directional singularity in the representation of images, and we evaluated its characteristics and layout implementation.

本研究では,乳児と母親のくすぐり遊びにおいて,いかに相互作用がなされているのかを明らかにし,そこにおいて意図理解がなされている可能性とその発達について検討した。観察開始時生後5ヶ月の母子1組を対象とし,3ヶ月間,家庭での自然観察を縦断的に行った。その結果,生後6ヶ月半の時点で,くすぐり刺激源(母親の手)と母親の顔との間で交互注視が起こり,その生起頻度は発達的に増加していた。さらに生後6ヶ月半頃のくすぐり遊びの行動連鎖について検討したところ,くすぐったがり反応が生じた事例では,身体に触れずにくすぐり行動を顔の前に提示する「くすぐりの焦らし」がなされた後に乳児がくすぐり刺激源を見る,くすぐり刺激源と母親の顔に視線を配分させる,「くすぐりの焦らし」において予期的にくすぐったがる,といったパターンが生起していた。このことから,生後6ヶ月半の時点で,乳児は母親とくすぐりの文脈を共有し,母親の意図を読みとりながら能動的に相互作用を楽しんでいることが示唆された。くすぐりの場は,身体部位を対象化することで成り立つ「原三項関係 proto-triadic relationship」(Negayama, 2011)の一例であると言える。そのような母子の身体を媒介項とした自然な相互作用における萌芽的な意図の読みとりが,三項関係における意図理解の成立への橋渡し的役割を担っている可能性が指摘された。

The drawing is made use of for assessment and treatment in the clinical psychology. The purpose of this study was to examine the effect of the kinetic family drawing and the kinetic school drawing. We were going to explain the effect using a concept called a feeling of physical self-expansion. As a result of having surveyed a precedent study of our country, it developed that a physical sense and a perception of the body movement played an important role. We trigger this physical sense and perception of the body movement, and the certified clinical psychologist must interpret drawing. The future problem is to accumulate a proof study. And it is to elucidate the source of the effect to have of the drawing.

A phylogenetic tree of visual pigments we have constructed, revealed that cone pigments evolved earlier than rhodopsins, so that color vision as well as photopic vision appeared earlier than scotopic vision. Conversions of cone pigments to rhodopsins in the process of evolution took place by replacing basic amino acid residues with neutral and/or acidic ones. A noteworthy difference between rhodopsins and cone pigments is that the rhodopsins are longer in lifetime of meta II-intermediate than cone pigments, which would be favorable for conducting the high photosensitivity of rods comparing cones. Chicken tetrachromatic vision was discussed using color diagrams.

「日本食品標準成分表」等のデータベースを用いて,茶と野菜の成分値を比較した結果,抹茶や玉露,煎茶を丸ごと食べることによって,ビタミンAやビタミンEの不足を補うことができる可能性が示唆された。しかし,茶を食す場合でも過剰に摂取することは禁物で,1人前1食分の上限を数グラムとし,香りや味,色合いなどを楽しむことに重点を置いて使用量を設定することが重要であると思われる。

Hyper-dual numbers (HDN) are numbers defined by using nilpotent elements that differ from each other. The introduction of an operator to extend the domain of functions to HDN space based on Taylor expansion allows higher-order derivatives to be obtained from the coefficients. This study inductively defines matrix representations of HDN and proposes a numerical method for higher-order derivatives, called HDN-M differentiation, based on the matrix representations of HDN. The proposed method is characterized so that higher-order derivatives can be computed with matrix operation rules without implementations of the operation rules of HDN.

Case: An 11-month-old boy bruised his head and experienced convulsions, followed by a coma with decerebrate rigidity. Initial CT scans showed an acute interhemispheric subdural hematoma and diffuse brain swelling. On day 2, he developed dilated pupils, absent light reflex, and sudden hypotension. Dopamine (DOA) and antidiuretic hormone (ADH) were administered to maintain his circulation. CT scans on day 3 revealed brain tamponade. The patient was diagnosed as brain dead on day 15. The patient was thereafter maintained under mechanical ventilation. DOA and ADH requirements decreased gradually, resulting in shift from DOA to docarpamine on day 146 and in the cessation of ADH administration on day 245. On day 139, autolysed brain parenchyma was discharged through the anterior fontanel and necrotic skin, resulting in the appearance of pneumocephalus on CT scans on day 299. Repeated EEGs, ABRs, dynamic CTs and intracranial Power Dopplers supported the diagnosis of brain death. Nevertheless, the patient's height increased consistently from 74cm on day 1 to 82cm on day 253. The secretion of thyroid stimulating hormone was detected until day 252. The boy developed septic renal failure and died on Day 326. Discussion and Conclusion: Although brain death in adults is usually followed by early cardiac arrest, the infant in this case was sustained in a state of brain death for over 300 days using ordinary intensive care. An analysis of endocrinological function and growth records may help to clarify the mechanism of the patient's sustained heart beat.

Recent evidence suggests that psychological stress is associated with gut microbiota; however, there are no reports of its association with gut microbial structure. This cross-sectional study examined the relationship between psychological stress and gut microbial patterns in young Japanese adults. Analysis of fecal microbiota was performed using terminal restriction fragment length polymorphism (T-RFLP). Psychological stress was assessed using salivary biomarkers, including cortisol, alpha-amylase, and secretory IgA (S-IgA). Fecal microbial patterns were defined using principal component analysis of the T-RFLP profile and were classified into two enterotype-like clusters, which were defined by the B (microbiota dominated by Bacteroides) and BL patterns (microbiota dominated by Bifidobacterium and Lactobacillales), respectively. The Simpson index was significantly higher for the BL pattern than for the B pattern. The salivary cortisol level was significantly lower for the BL pattern than for the B pattern. Salivary alpha-amylase and S-IgA levels showed a negative correlation with the Simpson index. Our results raise the possibility that salivary biomarkers may be involved in the observed differences in microbial patterns.

Rectal prolapse is associated with debilitating symptoms including the discomfort of prolapsing tissue, mucus discharge, hemorrhage, and defecation disorders of fecal incontinence, constipation, or both. The aim of treatment is to eliminate the prolapse, correct associated bowel function and prevent new onset of bowel dysfunction. Historically, abdominal procedures have been indicated for young fit patients, whereas perineal approaches have been preferred in older frail patients with significant comorbidity. Recently, the laparoscopic procedures with their advantages of less pain, early recovery, and lower morbidity have emerged as an effective tool for the treatment of rectal prolapse. This article aimed to review the current evidence base for laparoscopic procedures and perineal procedures, and to compare the results of various techniques. As a result, laparoscopic procedures showed a relatively low recurrence rate than the perineal procedures with comparable complication rates. Laparoscopic resection rectopexy and laparoscopic ventral mesh rectopexy had a small advantage in the improvement of constipation or the prevention of new-onset constipation compared with other laparoscopic procedures. However, the optimal surgical repair has not been clearly demonstrated because of the significant heterogeneity of available studies. An individualized approach is recommended for every patient, considering age, comorbidity, and the underlying anatomical and functional disorders.

The effects of three representative disinfectants, chlorine (sodium hypochlorite), iodine (potassium tetraglicine triiodide), and quaternary ammonium compound (didecyldimethylammonium chloride), on several exotic disease viruses were examined. The viruses used were four enveloped viruses (vesicular stomatitis virus, African swine fever virus, equine viral arteritis virus, and porcine reproductive and respiratory syndrome virus) and two non-enveloped viruses (swine vesicular disease virus (SVDV) and African horse sickness virus (AHSV)). Chlorine was effective against all viruses except SVDV at concentrations of 0.03% to 0.0075%, and a dose response was observed. Iodine was very effective against all viruses at concentrations of 0.015% to 0.0075%, but a dose response was not observed. Quaternary ammonium compound was very effective in low concentration of 0.003% against four enveloped viruses and AHSV, but it was only effective against SVDV with 0.05% NaOH. Electron microscopic observation revealed the probable mechanism of each disinfectant. Chlorine caused complete degeneration of the viral particles and also destroyed the nucleic acid of the viruses. Iodine destroyed mainly the inner components including nucleic acid of the viruses. Quaternary ammonium compound induced detachment of the envelope of the enveloped viruses and formation of micelle in non-enveloped viruses. According to these results, chlorine and iodine disinfectants were quite effective against most of the viruses used at adequately high concentration. The effective concentration of quaternary ammonium compound was the lowest among the disinfectants examined.
