90年代の不登校の増加は、子どもの心理発達の調整局面というより、子育て世帯に広がる生活困窮の広がりが強く作用した結果である。確かに、子どもの貧困率は2015年に改善が見られたものの、むしろ、母子世帯において格差が広がり、所得低位層に援助拒否が見られる。2009年より始まる訪問型家庭教育支援は、地域の人が親との雑談を大切にした支援を行ない、親の自己肯定感の回復につながり、不登校の子どもに就学意欲の改善が見られた。研究ノート(博士資格論文)(Note(Doctoral qualification thesis))

The All-Japan Judo Championships (AJJC) is an open-weight tournament for determining the best judoka in Japan. The AJJC has been held under the Kodokan Judo Refereeing Rules (KDK Rules) since 1951. In 2011, the All-Japan Judo Federation (AJJF) introduced the International Judo Federation Refereeing Rules (IJF Rules), which were formulated to facilitate more dynamic judo (increased wins by <i>ippon</i>, decreased wins by judges' decisions, and decreased <i>mate</i>-time). Although the IJF Rules has facilitated dynamic judo in international competitions, their effects on the competition contents in the AJJC are still unknown. Here, we aimed to clarify whether the introduction of the IJF Rules facilitated dynamic judo in the AJJC.<BR>The 221 judo matches in the AJJC from 2008 to 2013 were separated into two groups, the tournaments following the KDK Rules (2008-2010) and those following the IJF Rules (2011-2013). Their data were extracted from the AJJC records by<i> Judo</i>, the official Kodokan journal, and from the match videos recorded by the AJJF. We analyzed the proportions of winning contents (wins by <i>ippon</i> or superior performance), winning methods (points from techniques or penalties, or judges' decisions), techniques for getting points (<i>te-waza, koshi-waza, ashi-waza, sutemi-waza, </i>or<i> katame-waza</i>) and the <i>mate</i>-time for each match. A chi-square test and an independent <i>t</i>-test were used to perform statistical analyses, and for each test, statistical significance was assumed at <i>P</i> value < 0.05.<BR>For the winning methods of the IJF Rules' and the KDK Rules' tournaments, the proportion of points from techniques (60.4% vs. 53.6%) and points from penalties (23.4% vs. 15.5%) showed no differences, but the proportion of wins by judges' decisions in the IJF Rules' tournaments was significantly lower than in the KDK Rules' tournaments (16.2% vs. 30.9%) (P < 0.05). Furthermore, the <i>mate</i>-time in the IJF Rules' tournaments was significantly shorter than in the KDK Rules' tournaments (77 s vs. 105 s) (P < 0.01). However, the winning contents and techniques for obtaining points showed no differences between the IJF Rules' and the KDK Rules' tournaments.<BR>We confirmed for the first time that the IJF Rules did not affect the winning contents and techniques for getting points, but decreased the proportion of judges' decisions and <i>mate</i>-time in the AJJC. These findings suggest that the IJF Rules partially facilitated dynamic judo in the AJJC.
