In this paper, we analyze the relation between the stability of a noisy dynamical system based on linear approximation and the covariance matrix of its stationary distribution. We reformulate the theory of dynamical network biomarkers in terms of the covariance matrix and clarify the limiting behavior of the covariance matrix when a dynamical system approaches a bifurcation point. We also discuss the relation between the Jacobian matrix and principal component analysis. An application to a simple nonlinear network model is also demonstrated.

本報告は、近年理科教育等の分野で注目されている構成主義理論について、特に子ども達の興味・関心に関わる側面に対して、具体的な実態調査の結果をもとに、その理論の適応範囲を模索しようとするものである。本報告では、特にウィットロックの生成的学習モデル^<1)>における動機づけの理論との整合性を中心に検討したが、小学校6年はこの理論によく適合するが、3・4年では理論への適合というよりも、即物的に興味を示すことがわかった。このような結果は、構成主義で説明されるような認知的行動の発達によって解釈することの困難さを示している。

To analyze clinical characteristics and potential predictors of disease severity in patients with COVID-19.Clinical data from 64 patients with COVID-19 were retrospectively analyzed. Of the 64 patients, 37 were male and 27 were female. Their mean age was 47.8 years, 43 (67.2%) cases were non-severe, 21 (32.8%) were severe, and 2 patients (3.1%) died. Age and serum ferritin were significantly associated with COVID-19 severity. Repeated monitoring of ferritin, interleukin-6, C-reactive protein, lactic acid dehydrogenase, and erythrocyte sedimentation rate during COVID-19 treatment may assist the prediction of disease severity and evaluation of treatment effects. There were no significant differences in the duration of severe illness or the number of days on high-level respiratory support between a low-dose methylprednisolone group and a high-dose methylprednisolone group. The mean number of days in hospital in the high dose group was higher than that in the low-dose group. Repeated monitoring of ferritin, interleukin-6, C-reactive protein, lactic acid dehydrogenase, and erythrocyte sedimentation rate during COVID-19 treatment may assist the prediction of disease severity and evaluation of treatment effects.

文脈化神学は、ここ数十年の間に社会正義から文化的自己表現へとその関心を移してきた。ポストモダンの諸文化理論もこの変化を後押しし、神学の自己理解もこれに新たな意義を認めるようになった。なかでもアジア神学は、キリスト教史に占める時代史的な先端性のゆえに、今では文脈化神学の主要な担い手となりつつある。この視点から近年の「日本的キリスト教」理解を検討すると、そこには外からの視線で日本の日本らしさを規定するオリエンタリズムの関与が疑われる。加えて、従来無視されてきた非正統的な宗教集団に「みずからを語らしめる」という社会学的な接近方法は、研究者=救済者という構図を生んでポストコロニアル批判を招く。アジア神学がこのような虚構性に敏感であらざるを得ないのは、みずからもアジアの「アジア性」について繰り返し問い続けているからである。最後に本稿は、アジア神学を「アジアから神学を問う」ないし「アジアによって神学を問う」という「奪格的神学」の試みとして説明する。

[Purpose] External focus (EF) instructions demonstrate a learning effect on motor performance enhancement. However, the effective EF distance during standing long jump performance of non-athletes has not been clarified. This study aimed to determine the effects of EF at different distances on jumping performance. [Participants and Methods] A total of 40 non-athlete participants were randomly divided among four groups. The no attention line group performed a standing long jump without the attention line on the floor; those in the −20-cm EF group, the ± 0-cm EF group, and +20-cm EF group performed the jump attention line with an attention line 20-cm posterior, at ± 0 cm, and 20-cm anterior as the reference jump distances, respectively. [Results] The mean rate of increase between the first to second jump distances in the +20-cm EF group was higher than that in the no attention line group. The rates at which the jumpers reached the attention line in the ± 0-cm EF group and the +20-cm EF group were lower than the rate in the −20-cm EF group. [Conclusion] Instructions are more effective when the distance to the attention line exceeds jumping performance.

SLEは出産可能年齢の女性に多い疾患であるが,高齢発症のSLEも決してまれではない.50歳以降の発症を高齢発症SLE (late-onset) と定義する報告が多く,日本の特定疾患受給者をもとにした報告では50歳以降の発症が全体の30%近くを占めている.高齢発症例では若年発症例に比べ,男女比が低く,漿膜炎,神経症状を認める割合が高く,蝶形紅斑,光線過敏症が少ないといった特徴がみられる.また,高齢者ではSLEが鑑別にあがりにくく,典型的な症状が出にくいことや薬剤誘発性ループスをはじめとする鑑別疾患が多岐にわたるため診断までに時間がかかることも特徴とされている.治療については,海外でいくつかのガイドラインが発表されており,ステロイドと免疫抑制剤(ミコフェノール酸モフェチル内服もしくはシクロホスファミド点滴静注)の併用による寛解導入療法が推奨されている.しかしながら高齢者では腎機能や免疫力の低下も多くみられるため,副作用を考慮し,個々に応じた投薬の調整が必要である.

Aircrafts making landing and takeoff at Narita International Airport (Narita Airport) in Japan report frequently low-level wind shear (LLWS), a local variation of wind vector, with turbulence when the prevailing wind is southwesterly, which is crosswind to the runway direction. On 20 June 2012, an arrival aircraft at Narita Airport encountered a LLWS, which consisted of a sudden change of the wind vector from head wind component of 5 knots (2.6 m s-1) to tail wind component of 10 knots (5.1 m s-1), just before the touchdown and made a hard landing. None of cumulonimbus clouds, a front or a wind shear line was observed around the airport during her approaching and landing. Analyses of the data measured by the landing aircraft and the observations by the Doppler lidar at the airport revealed that the LLWS was caused by horizontal roll vortices, which developed in the atmospheric boundary layer (ABL) over the Shimofusa Tableland around the airport. The horizontal roll vortices had their axes nearly parallel to the mean wind direction, and their horizontal and vertical scales were approximately 800 m and 500 m, respectively. The present study demonstrated that existence of the horizontal roll vortices causing LLWS can be effectively detected by a single-Doppler lidar which utilizes backscattering from aerosols. Although the LLWS associated with the horizontal roll vortices has smaller magnitude than those caused by a microburst, a gust front and a front, a landing aircraft just before touchdown encounters the horizontal roll vortices with much higher probability than the other phenomena mentioned here since the horizontal roll vortices occurs at a horizontal spacing of approximately 800 m over a wide area during daytime of a clear day.

Background: The World Health Organization declared the novel coronavirus outbreak (COVID-19) to be a pandemic on March 11, 2020. Large-scale monitoring for capturing the current epidemiological situation of COVID-19 in Japan would improve preparation for and prevention of a massive outbreak.Methods: A chatbot-based healthcare system named COOPERA (COvid-19: Operation for Personalized Empowerment to Render smart prevention And care seeking) was developed using the LINE app to evaluate the current Japanese epidemiological situation. LINE users could participate in the system either though a QR code page in the prefectures’ websites or a banner at the top of the LINE app screen. COOPERA asked participants questions regarding personal information, preventive actions, and non-specific symptoms related to COVID-19 and their duration. We calculated daily cross correlation functions between the reported number of infected cases confirmed using polymerase chain reaction and the symptom-positive group captured by COOPERA.Results: We analyzed 206,218 participants from three prefectures reported between March 5 and 30, 2020. The mean age of participants was 44.2 (standard deviation, 13.2) years. No symptoms were reported by 96.93% of participants, but there was a significantly positive correlation between the reported number of COVID-19 cases and self-reported fevers, suggesting that massive monitoring of fever might help to estimate the scale of the COVID-19 epidemic in real time.Conclusions: COOPERA is the first real-time system being used to monitor trends in COVID-19 in Japan and provides useful insights to assist political decisions to tackle the epidemic.

In Japan’s modern era land readjustment system is a very important procedure of urban development. In the land readjustment area of Kyoto city we are able to find some historical transitions in the layout method of “machi”, the minimum unit of town community. The city’s technical guidelines in 1935 adopted street conscious method in “machi” layout. One “machi” was settled on both sides of a street. A street was the axis of a “machi”. This is similar to the traditional structure of the Kyoto city. This guideline was canceled in 1972 by new technical guideline which had the block conscious method. But in reality, street conscious method had been abandoned in 1940’s. In this city’s western area, there are several land readjustment areas in full of variety in built-up time. In this paper we compare them one another, and analysis relationship between their “machi” layout and social and physical conditions in those days.

This study aims to explore how the relationship between punitiveness and attributional style differs between Japan and Korea. Data from 330 Japanese and 339 Koreans were analyzed. Multi-group structural equation modeling showed that in both Japan and Korea, punitiveness consisted of three factors (support for harsher punishment, greater criminalization, and use of the death penalty) while the attributional style consisted of two factors (dispositional attribution and situational attribution). In both countries, dispositional attribution was related to punitiveness. Regarding differences, the scores for punitiveness on all three subscale scores and for dispositional attribution were higher in Korea whereas the negative relationship between punitiveness subscale scores and situational attribution was stronger in Japan. This suggests that Japanese are less likely to support punitive measures for criminals and to attribute the causes of crime to the criminals themselves than Koreans. In addition, when deciding on the severity of punishment, Japanese are more likely to take situational causes into consideration.
