The coronavirus first reported in China in November 2002 in the form of atypical pneumonia known as the severe acute respiratory syndrome (SARS).[1] The virus then appeared in 2012 in Saudi Arabia as the middle East respiratory syndrome (mERS).[2] The year 2020 witnessed a novel β-coronavirus related to the previous detected viruses.[3] It was the severe acute respiratory syndrome coronavirus 2 (SARS-Co V-2)-a positive single stranded RNA virus.

In the United States, children are not meeting daily recommendationsfor 60 min of moderate・to・vigorous activity.1Because children spend a large portion of their days in school, ithas been further recommended that children accumulate 30 minof their physical activity (PA) during school hours.2 Our previousresearch has demonstrated with objective measures that only8%—9% of elementary school children meet this goal, with anaverage accumulation of 18 min/day.3,4 This finding is of concerngiven the numerous benefits that PA has not only on healthoutcomes,5-8 but also on academic achievement.9 For example,there is heightened awareness that children benefit from PAthroughout the school day in terms of attention to task, memory,behavior, and, ultimately, academic performance.10 Schooladministrators acknowledge this link, but still face barriers toincorporating PA for schoolchildren, including limited time andresources for physical education (PE) and recess.

Despite a half century of below-replacement fertility,Japan is typically not included in discussions and evaluations of the second demographic transition(SDT),a widely referenced framework for understanding family changes and attitudinal shifts associated with very low fertility.I address this limitation by drawing upon a range of published research and data sources to provide an empirical basis for thinking about how the Japanese experience does or does not conform to the general patterns of behavioral and attitudinal change associated with the SDT in the *** this evidence,it seems clear that the prototypical pattern of family change in Northern and Western Europe has only partially emerged in *** same is true of attitudes,particularly those related to *** with depictions of the SDT in Europe,Japan has experienced substantial delays in marriage and childbearing along with notable increases in non-marital cohabitation and ***,non-marital childbearing has remained at negligibly low levels and cohabiting unions have not emerged as an alternative to *** data show that endorsement of conventional family patterns and gender roles has declined,but remains at higher levels than in most SDT *** as a whole,these data describe a distinctive path to very low fertility in which universal forces of social and family change interact with strong normative expectations of two-parent families characterized by a clear gender division of labor.

A new stilbene diglucoside, gnetifolin K, was isolated from the lianas of Gnetum parvifolium. Its structure was established as isorhapotigenin-3,4'-di-O-beta-D-glucoside on the basis of spectral and chemical evidence.

In the present paper, it is shown that, for a locally compact commutative hypergroup K with a Borel measurable weight function w, the Banach algebra L^1 （K, w） is semisimple if and only if L^1 （K） is semisimple. Indeed, we have improved compact groups to the general setting of locally a well-krown result of Bhatt and Dedania from locally compact hypergroups.
