Many children in Japan today do not know how to grasp a pencil or use chopsticks properly. Improper pencil grasp and chopstick usage may have a negative impact on one's studying and eating posture. In addition, improper posture potentially leads to poor eyesight. This survey was conducted to examine how pencil grasp and chopstick usage may affect the seated posture among children with the aim of putting a stop to the increasing number of children with poor eyesight. Of all the children surveyed, approximately 30% improperly grasped pencils while approximately 25% improperly used chopsticks. The survey result shows that pencil grasp and chopstick usage are associated with studying (seated) posture. By means of proper pencil grasp and chopstick usage, children were more likely to maintain a distance of 30 cm or more between the eyes and the notebook surface. This is known to impose minimal strain to the eyes. In fact, those children who maintained this optimal posture were less likely to have poor eyesight compared to those who did not. In view of these facts, encouraging efficient pencil grasp and proper chopstick usage among children will contribute to promoting the optimal studying posture that imposes minimal strain on the eyes. Until children are old enough to understand what needs to be done to maintain good eyesight, parents and adults should provide necessary care and support in this respect.

本論文では日本語の句構造文法JPSGとそのパーサについて述べる.JPSGは最新の句構造文法理論であるGPSGやHPSGの基本的な考え方を用い,更に日本語特有の言語現象を扱うために独自の原則を導入した日本語の文法記述体系である.特に統語範疇の集合を値とする下位範疇化素性(SUBCAT)により語順の任意性やコントロール現象が扱い易くなり,句構造規則の一般化が可能である.またJPSGはユニフィケーションを基本操作とする句構造文法であるため,計算効率の面からも有用な文法体系であり,その特徴を自然な形で記述できる論理型言語でパーサを開発中である.
