There are many students and pupils who bring dinking water, such as water and tea which are bottled in their own water bottle at home, to the school. Since its hygiene was concerned, our last research was carried on the situation of the bacterial contaminations of those bottled waters. Then it has been found that there were serious bacterial contamination situations of those bottled water, which had made us continue the research to get more certain findings. The results of this continuous research could make it more certain that the high level of the bacterial contamination in those bottled waters does exist. To compare to the drinking water quality standards of the water supply, more than 90% of those bottled waters were found to be incongruent, besides the contamination with Escherichia coli. The levels of the bacterial contamination found were higher in the raining season than the fall. In this research, to investigate the cause of the bacterial contamination, some of the dinking water before bottled were collected separately to sterilized containers at the same time they were poured into the water bottle at home. As a result, the levels of the bacterial contamination of the bottled water were higher than the water which were collected separately, and it was suggested that the bacterial contamination was likely be generated by putting in the water bottle.

We have two chapters in this study. The details are as follows; Chapter 1. This chapter is the sequel to our treatise reported in the preceding Bulletin of The Faculty of Education Univ. of Tokyo Vol. 15. In that Bulletin, we hypothesized that the effect of noises on psychological performance was not merely inhibitory but also accelerating, designated them as "inhibitory effect" and "accelerating effect". The main purpose of this chapter is to investigate these two effects, in case of performing Intelligence-Tests which has 5 intellectual factors from simplicity to complexity. Experimental conditions and procedures are as follows ; Test : Intelligence-Test, known as Todai A-S form. Noise conditions : Control group-about 40 dB(A), Experimental group-White noise 80 dB(A), produced by Noise Field Generator, placed at the center of the experimental rooms. Grouping: 3 groups. Gl-Control. G2-Experimental, doing the test in Usual Sequence, G3-Experimental, doing the test in Reverse Sequence. Subjects : The first and the second year Junior High School, about 50 members in each group. The main findings of this chapter were shown under. Concerning the complex intellectual factors in intelligence-test, "inhibitory effect" came first which was shown in Reverse Sequence Group : G3. But in the simple intellectual factors, " accelerating effect" had a tendency to come first, which was same as Kroeperin-Test composed of mathematical computation. Anyway two effects mentioned the above had different influence upon intellectual factors by the degree of complexity. Chapter 2. In this chapter, we investigated the effect caused by exposure to the music, by carrying out experimentally on 173 male and 173 femail junior high school pupils engaged in some intellectual performance. The findings of this chapter were as follows ; 1. The intellectual performance in the case of the quiet condition was more efficient in comparison with that of the music exposure, 2, The inefficiency under the music was not related to the degree of the undesirability against music, but related to the degree of the unfamiliarity with music.

We have two chapters in this study. Chapter 1. The main purpose of this chapter is to investigate the effect of Back Ground Music (B. G. M. ) , especially the effect of masking nuisance noises, in case of pupils' performing Intellectual-Tests. And we also investigated the reason why pupils learned their lessons at their homes under the conditions of B.G.M.. The main findings of this chapter is as follows; 1. B.G.M. used to mask nuisance noises softens the suffering given by nuisance noises. 2. In case of performing Intellectual-Tests, the condition under "B. G. M. with nuisance onises" is more efficient than that under "noises only". 3. The main reason of pupils' learning under the conditions of B.G.M. is not that they want to increase the efficiency of their lessons but that they want to listen to music itself. Chapter 2. This chapter is the sequel to our treatise reported in the preceding Bulletin of the Faculty of Education, Univ. of Tokyo, Vol. 16. We investigated whether the effect of music upon intellectual performance varies by each subject's skillfulness or not. We have the following conclusion. "Inhibitory effect" of music was obviously observed in those subjects who had lower skillfulness in performing Intellectual-Tests.

ライフスキル形成を強化する第二次の食生活教育プログラム改訂,指導者マニュアル作成,授業担当者研修,意志決定スキル,目標設定スキル尺度開発,家族への働きかけを試み,以下の成果を得た.I.2005年6月〜2006年7月,大阪府下の6小学校と山口県2小学校を研究対象校とする準実験デザインのもと,健康的な間食行動と朝食行動を主題とするスキル形成に焦点をあてた食生活教育プログラム(18時間)を実施し,計810名が参加した.(i)プロセス評価より,意志決定の下位尺度「選択肢の列挙」「結果の予測」を踏まえたおやつ選択法を,「意志決定をすべき問題の明確化」を踏まえ,朝食で野菜を食べるために具体的な,実行可能な目標設定ができた.(ii)影響評価より,女子は,健康的な間食行動の態度,自己効力感が高まり,低油脂おやつの選択が増加した.野菜摂取に焦点をあてた朝食学習により,朝食の野菜摂取率はおよそ倍増し,栄養バランスを改善した.(iii)意志決定スキル形成群において介入校の児童は,広告分析に関する自己効力感や食品選択スキルに有意な成果が認められたが,対照校児童には規則性はみられなかった.II.大阪府下の3小学校と山口県3小学校を研究対象校とし,2007年5月〜7月に,保護者通信,朝食モニタリングシートの家族点検,家庭での朝食野菜料理など保護者への働きかけを強化した朝食プログラム(6時間)を実施した.計417名が参加した.(i)全児童は,目標達成率,朝食の栄養バランスともに有意に高くなった.(ii)授業実施6カ月後には,児童の学習成果は有意に低下したものの家族強化群は,対照群に比べ,朝食得点,野菜摂取率ともにやや高い維持率を示した.さらにプログラム効果を高め,持続するために,教材や指導者研修,家族強化の改善を図り,学校健康教育に普及していく.
