An anomalous hydration/dehydration sequence for the mild generation of a nitrile oxide
A nitrile oxide containing a carbamoyl group is readily generated upon the treatment of 2-methyl-4-nitro-3-isoxazolin-5(2H)-one with water under mild reaction conditions, even in the absence of special reagents. The obtained nitrile oxide undergoes cycloaddition with dipolarophiles, alkynes and alkenes, to afford the corresponding isoxazol(in)es, which are useful intermediates in the synthesis of polyfunctionalized compounds. A plausible mechanism underlying the formation of the nitrile oxide is proposed, which involves an anomalous hydration/dehydration sequence. DFT calculations were also performed to support this mechanism

Subaru Imaging of Asymmetric Features in a Transitional Disk in Upper Scorpius
We report high-resolution (0.07 arcsec) near-infrared polarized intensity
images of the circumstellar disk around the star 2MASS J16042165-2130284
obtained with HiCIAO mounted on the Subaru 8.2 m telescope. We present our
-band data, which clearly exhibits a resolved, face-on disk with a large
inner hole for the first time at infrared wavelengths. We detect the
centrosymmetric polarization pattern in the circumstellar material as has been
observed in other disks. Elliptical fitting gives the semimajor axis, semiminor
axis, and position angle (P.A.) of the disk as 63 AU, 62 AU, and -14
, respectively. The disk is asymmetric, with one dip located at P.A.s
of . Our observed disk size agrees well with a previous study
of dust and CO emission at submillimeter wavelength with Submillimeter Array.
Hence, the near-infrared light is interpreted as scattered light reflected from
the inner edge of the disk. Our observations also detect an elongated arc (50
AU) extending over the disk inner hole. It emanates at the inner edge of the
western side of the disk, extending inward first, then curving to the
northeast. We discuss the possibility that the inner hole, the dip, and the arc
that we have observed may be related to the existence of unseen bodies within
the disk.Comment: 21 pages, 3 figures, published 2012 November 7 by ApJL, typo

Verification of the effects of parent-child learning sexual health education programs on sexual health education practices at home
本研究の目的は、国際セクシュアリティ教育ガイダンスをもとに作成した性の健康教育プログラムが、家庭での性の健康教育実践に及ぼす効果を検証することであった。対象は5歳~8歳の子どもとその保護者で、プログラムには4組の親子(子ども5名、保護者4)が参加した。しかし、新型コロナウイルス感染症の感染状況により実施が2022年度4月となってしまい、今現在プログラム終了後の家庭での様子(性の健康教育実践)についてインタビューを実施している最中である。各プログラム後に実施した質問紙調査から、全体を通しての満足度は高く、開催時間・時期の妥当性は伺えた。また、プログラムを通して子ども達の仲も大変よくなっていき、それに伴いプログラム中の発言回数が増加し、リラックス感も高まっていった。このことから、保護者・子ども双方のグループダイナミクスを意識したプログラム編成を再考する必要があると考えている。今後インタビュー内容を丁寧に分析し、このプログラムをさらに発展させていきたい。othe
