Variation in Mitochondrial DNA of Vietnamese Pigs: Relationships with Asian Domestic Pigs and Ryukyu Wild Boars

Mitochondrial DNA (mtDNA) sequences (574 bp) of 30 Vietnamese pigs (large and small) were examined and compared with those of 61 haplotypes from wild boars and domestic pigs from various locations in Asia. The large Vietnamese pigs had genetic links to Ryukyu wild boars in southern Japan. The small Vietnamese pigs were closely related to other East Asian domestic pigs. These results indicate that Vietnamese pigs are genetically diverse and may be descendents of wild and domestic pigs from other regions of Asia

Synthesis of chitosan resin possessing 3,4-diamino benzoic acid moiety for the collection/concentration of arsenic and selenium in water samples and their measurement by inductively coupled plasma-mass spectrometry

A chitosan resin functionalized with 3,4-diamino benzoic acid (CCTS-DBA resin) was newly synthesized by using a cross-linked chitosan (CCTS) as base material. The adsorption behavior of trace amounts of elements on the CCTS-DBA resin was examined by the pretreatment with a mini-column and measurement of the elements by inductively coupled plasma-Mass spectrometry (ICP-MS). Arsenic(V) could be retained on the CCTS-DBA resin at pH 3 as an oxoanion of H(2)ASO(4)(-). Selenium(VI) is strongly adsorbed at pH 2 and pH 3 as an oxoanion of SeO42-. while selenium(IV) as HSeO3- is adsorbed on the resin at pH 3. The sorption capacities are 82, 64, and 88 mg g(-1) resin for As(V), Se(IV), and Se(VI), respectively. The effect of common anions and cations on the adsorption of As(V), Se(IV), and Se(VI) were studied; there was no interference from such anionic matrices as chloride, sulfate, phosphate, and nitrate up to 20 ppm, as well as from such artificial river water matrices as Na, K, Mg, and Ca after passing samples through the mini-column containing the resin. The CCTS-DBA resin was applied to the collection of arsenic and selenium species in bottled drinking water, tap water, and river water

最重度児を含む重度・重複障害児のスヌーズレン授業 に関する全国調査研究 : 肢体不自由特別支援学校(知肢等併置校を含む)における実施状況の分析

肢体不自由特別支援学校の重度・重複障害児へのスヌーズレン授業に関する調査研究は2015年に発表されている。今回これまで報告されていないスヌーズレン室の設置状況や授業内容を中心に、全国327校の肢体不自由特別支援学校の小学部を対象に予備調査を実施した。調査時期は2021年6月から7月。調査方法は質問紙調査を用い回収率は51.4％、168校から回答があった。その結果、主に1990年前後からスヌーズレン室を設置して授業が開始され、2021年現在40校(回収校の約24％)に設置され、2012年調査時に比べて2倍程度増加していた。スヌーズレン授業の単元・題材名は「光遊び」「クリスマス遊び」が多用され、実施時期は12月の冬が最も多く、定期的な実施が約3割から約4割に漸増していた。この結果、最重度児を含む重度・重複障害児へのスヌーズレン授業を実施する学校が年々増え続け、この授業の必要性が教師間に広く認識されてきたと考えられた。訂正記事ありdepartmental bulletin pape
