Recently, "Virtual Reality"(VR) has become one of the most attractive new technologies. VR isalso knownas"Virtual Environment", or VE. Inthis paper, we usetheterm "VE" because we are not working on training simulators but instead on systems for general users. VE technology has rapidly advanced and offers many promising applications in such areas as training, medicine and so on. However, a potential hazard to users of virtual environments has been found: some users complain of discomfort during and after the experience. This phenomenon is similar to motion sickness and has been called "simulator sickness". There is a direct link between simulator sickness and sickness in virtual environments: both are forms of visually-induced motion sickness. However, we believe there is a significant difference between general-purpose VE and simulators for special training. This report surveys the literature on simulator sickness and motion sickness in relation to discomfort in virtual environments, especially from the point of view of autonomic nervous system (ANS) responses. We hopethis research can suggestways to combat such risksto users and contribute to the expansion of safe VR and VE technologies.

The purpose of the present study was to clarify the effects of positive ideal-real self discrepancy, negative ideal-real self discrepancy, and irrational belief on self acceptance. A total of 464 university and vocational school students, an average of 21.1 years old, participated. Results confirmed the prediction that the smaller the positive ideal-real discrepancy, and the larger negative ideal-real discrepancy, the higher is the self acceptance score. It was also found that the effects of the positive ideal-real self discrepancy depended on the intensity of irrational belief, and the belief was thus a moderator of the effect. On the other hand, the intensity of irrational belief did not moderate the effect of negative ideal-real self discrepancy. Finally, the findings were discussed in relation to the effectiveness of psychotherapeutic and counseling efforts to enhance self acceptance.

Background:The aim of our study was to investigate in detail the temporal trends in in-hospital characteristics, actual management, and survival, including neurological status, among adult out-of-hospital cardiac arrest (OHCA) patients in recent years.Methods and Results:From the prospective database of the Comprehensive Registry of Intensive Care for OHCA Survival (CRITICAL) study in Osaka, Japan, we enrolled all OHCA patients aged ≥18 years for whom resuscitation was attempted, and who were transported to participating hospitals between the years 2013 and 2017. The primary outcome measure was 1-month survival with favorable neurological outcome after OHCA. Temporal trends in in-hospital management and favorable neurological outcome among adult OHCA patients were assessed. Of the 11,924 patients in the database, we included a total of 10,228 adult patients from 16 hospitals. As for in-hospital advanced treatments, extracorporeal cardiopulmonary resuscitation (ECPR) use increased from 2.4% in 2013 to 4.3% in 2017 (P for trend <0.001). However, the proportion of adult OHCA patients with favorable neurological outcome did not change during the study period (from 5.7% in 2013 to 4.4% in 2017, adjusted odds ratio (OR) for 1-year increment: 0.98 (95% confidence interval: 0.94–1.23)).Conclusions:In this target population, in-hospital management such as ECPR increased slightly between 2013 and 2017, but 1-month survival with favorable neurological outcome after adult OHCA did not improve significantly.

ヨリメグモの網構造について調査した。このクモは流水面上に網を張り, 二つの型がみられた。一つは網の上部に支持糸を持った水平円網であり, 他の一つは基本的には水平円網だが, ヨコ糸が垂れ下がって水面に達しているために変形していた。そして, ヨコ糸と水面との接点には多くの細かい糸がみられた。ヨコ糸を張り終えたクモは, こしき部とヨコ糸との間においてタテ糸を切断し, それらのタテ糸をゆるめた。タテ糸がゆるめられると, 変形網のヨコ糸は流水上に浮遊するために, この網を浮遊網と名付けた。網の形は, 造網場所の条件に影響された。浮遊網は水面上の比較的低いところにみられたが, 水平円網は水のない場所や水面上の比較的高い場所にみられた。これらのことから, ヨリメグモは円網種に由来し, 流水環境に適応したクモであると考えられた。

Per risolvere la nota contraddizione ("rompicapo", a detta della Corti) fra le due opere di Dante intorno alla "Donna Gentile", alcuni studiosi, fra i quali il Pietrobono e il Nardi, hanno proposto l'ipotesi di una dopia redazione, secondo la quale la prima redazione del "libello" si sarebbe conclusa con il sopravvento della "Donna Gentile" "Filosofia" su Beatrice ; Dante avrebbe successivamente rimaneggiato la redazione anteriore nell'intento di farne un prologo alla Commedia, quando ormai il progetto del viaggio per l'oltretomba attraeva completamente la mente del poeta ; e sarebbe di una seconda redazione la Vita Nova giuntaci nella forma oggi nota, dove l'ulteriore evolversi del pensiero di Dante avrebbe determinato il capovolgimento dell'amore per la "Filosofia" in "malvagio desiderio" e sconfitta. Tolta la possibilita di dimostrare direttamente che Dante avesse o non avesse mai redatto diversamente la Vita Nova in un primo tempo e data la scarsita degli indizi che, a mo'di schegge archeologiche, permettano la ricostruzione di una fase per la quale l'immaginazione di Dante sarebbe eventualmente passata, tutto il problema non puo non rientrare nel dominio della probabilita e dell'interpretazione : la contraddizione va messa in relazione, per cosi dire, con il complesso delle costellazioni e il nodo si dovrebbe sciogliere soltanto alla luce della legge generale dell'universo dello scritto dantesco. L'ipotesi di una doppia redazione presuppone un Dante"logico" fra la presunta prima redazione della Vita Nova e il Convivio e fra quest'ultimo e la seconda redazione del "libello", senza domandare, pero, di quale natura sia il primo mobile che mette in moto tutti i cieli dell'universo dantesco. Chiedere a Dante la coerenza logica, dunque, potrebbe comportare il rischio di non rispettare anzi di fare violenza alla natura piu intima di tutto il suo cosmo e l'individuazione di una costante nel poeta dovrebbe precedere l'assunzione di un qualche atteggiamento nei confronti del "rompicapo" in questione. Chi scrive qui, ispiratosi al "libro de la memoria" osto sulla soglia della Vita Nova, provera ad individuarla nell'auto-citazione legata inscindibilmente con l'ermeneutica che sottopone, come segno, il passato a nuove interpretazioni. Se il meccanismo del sottile recupero del passato e per sua natura sempre destinato a produrre contraddizioni insieme a nuove interpretazioni, quale significato ha chiedere al poeta la coerenza logica? La Vita Nova dovrebbe essere letta in chiave religiosa-cristiana oppure laica-cortese? Quale valore ha lo scritto di Dante in quanto testimonianza biografica? Quale importanza ha la filosofia scolastica nella formazione culturale del poeta? Tutti questi problemi sono in stretta connessione con la nostra discussione. In breve, il problema della contraddizione intorno alla "Donna Gentile" fra la Vita Nova e il Convivio e essenziale per la comprensione non soltanto del carattere fondamentale del "libello" giovanile, ma anche della personalita di Dante.

Yanagita Kunio clarified that the word “Senzo” (Japanese traditional concept of ancestors) is used in two different meanings in his “Senzo-noHanashi” (1946). One meaning is the founder of “Ie” (the stem family), and the other is all of its deseased members. This paper points out that his study was based on his formula on the the relations between “Ie” and society. He regarded social mobilization in modern Japan as a serious problem to the eternal continuation of “Ie” and the society which is organized by “Ie” s. This problem let him pay attention to two meanings of “Senzo”. Through the reviewal of his studies, we will try to find a possibility to build a new hypothesis about the relation between social mobilization and ancestor worship in modern Japan.

サーチュインは健康長寿を支える遺伝子とされ,ほとんどの生物にある。その実体は,有核生物では,主としてヒストン,p53他のアセチル化タンパク質を基質とするNAD+依存性リジン脱アセチル化酵素,原核生物では,コバラミン合成に関するcobBとして同定された後,代謝酵素,転写制御因子及び走化性タンパク質の脱アセチル化に関わると報告された。一方プロバイオティクスとして注目されている乳酸菌もサーチュインを持つが,その役割は不明であった。乳酸菌自身にとっても,サーチュインは健康維持の長寿遺伝子なのか?それが本研究の出発点であった。プロバイオティクスや醗酵のスターターに用いられてきたLactobacillus paracaseiを対象として,まず遺伝子sirAをクローニングすることから手掛け,組換えタンパク質LpSirAを作成した。次にLpSirAのリジン脱アセチル化酵素反応を検証し,その細胞内基質の一つが30Sリボソームタンパク質S4であることを見出した。続いて,抗LpSirA抗体を作り,菌体細胞内のサーチュインの局在を,免疫染色法及び蛍光タンパク質融合による生細胞の観察,最終的には免疫電子顕微鏡撮影したところ,細胞全長にわたる緩めの螺旋状の局在,または細胞分裂面と細胞極に濃密に局在することを発見した。更にsirA欠損株,sirA過剰発現株を作成してみると,野生株に比べてsirA欠損株は細胞長が短く,逆にsirA過剰発現株は細胞長が長いことが判明した。これらの結果は,タンパク質合成制御に加えて,サーチュインが細胞分裂と細胞形態形成という,生命維持に本質的な機能を持つことを示した。更にストレス耐性に関与するデータも得て,乳酸菌サーチュインを人為的に制御することができれば,プロバイオティクスとしての機能を高め,ひいては宿主の健康長寿維持にも役立つ可能性があるのではないかと考えるに至った。

近年,Twitter をはじめとするマイクロブログを利用した商品やイベントの告知に対し,多くのユーザが感想など告知の投稿者やその告知への感想に関心があるユーザにとって有益な関連投稿を行うようになってきている.しかし,関連投稿の多くは告知投稿とは明示的に関連付けられてはいないため,告知の投稿者がこれらの関連投稿を見つけるのは容易ではない.そこで本研究では,特に Twitter の機能であるリツイートに注目し,告知に対する非明示的な関連投稿を効率的に収集する手法を提案する.Events, festivals or product releases are often announced via microblogs such as Twitter. Many users post messages that are relevant to the announcements. Such relevant posts are useful for both the authors of the announcements and the users who are interested in public opinions to the announcements. However, it is not easy to collect such relevant posts because many of the relevant posts are not explicitly associated with the announcement post. In this paper, we propose a method for efficiently collecting such posts that are only implicitly relevant posts to announcements, focusing on retweets of Twitter in particular.
