• 基盤研究(C), 01 Apr. 2020 - 31 Mar. 2023, 20K02336, フレイル高齢者の住環境・住まい方の実態と環境調節行動を促す介入に関する研究, 東 実千代; 大友 絵利香; 久保 博子; 佐々 尚美; 小濱 朋子; 磯田 則生, 日本学術振興会, 科学研究費助成事業, 畿央大学, 4290000, 3300000, 990000, 2021年度は自立した生活を送っている奈良県都市部在住の高齢者24名（継続）、農村部在住高齢者20名（新規）を被験者としてフレイル度調査を行うとともに、夏期において室内温熱環境の実測、住まい方調査、日中の活動量測定を実施した。熱中症予防行動の促進に用いる介入ツール（室内温熱環境可視化ツール）については、2020年度の課題分析結果に基づいてデザインを再検討した。概要は以下の通りである。
  【フレイル度調査】近い将来介護が必要となる危険の高い高齢者を抽出する目的で開発された基本チェックリストによる調査を実施した。被験者の年齢は平均80歳±6歳であり、総合得点を3段階（健康・プレフレイル・フレイル）に分類して判定したところ、健康が約3割、プレフレイルが約5割、フレイルが約2割であった。判定には日中の活動レベルとの相関が認められたが、年齢やBMIとの関連性はなかった。活動レベルは男性が女性がより高く、都市部が農村部より高い傾向がみられた。一方、主観的健康感は農村部が都市部より高いことから、性差や地域差を考慮した評価・解釈が必要であると考えられた。
  【室内温熱環境実測・住まい方調査】2001年8月上旬から中旬を主な測定期間としたため、雨天日が多く猛暑日の温熱データが十分に取得できなかった。農村部においてはエアコンの使用率が低く、室温を確認する習慣のある人が少ない傾向があり、夜間に室温が高い事例が散見されるなど、熱中症予防の意識や予防行動の実践状況には改善の余地があると考えられた。
  【室内温熱環境可視化ツール】人工気候室における高齢者の温熱生理反応のデータをもとに、熱中症予防行動を促すべき温度帯を検討し、その範囲で変色するインキを用いた室内温熱環境可視化ツールを作成した。精度検証実験を行った結果、指定とした温度で精度よく変色し、色変化は高齢者の視覚特性に対応したものであることが確認された。, kaken

• Grant-in-Aid for Scientific Research (B), 01 Apr. 2016 - 31 Mar. 2019, 16H03027, The survey of seasonal variations in thermal environment and Healthrelated Quality of Life of the elderly, Kubo Hiroko, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Nara Women's University, 16640000, 12800000, 3840000, Focusing on the indoor thermal environment and seasonal changes in daily life, we conducted an actual measurement survey of living environment and life behavior of the elderly who were independent for the purpose of understanding the effects on the quality of life and health of the elderly. Furthermore, multivariate analysis was conducted to examine seasonal changes in daytime activity, sleep, physical fitness, number of steps, and health-related quality of life and their relationship. As a result, it was suggested that the thermal environment may affect the health-related quality of life score through sleep quality and thermal comfort. In addition, many elderly people, including frail elderly people, do not control the indoor environment much, and they lived at low temperature in winter and lived in summer. It was suggested that their lives would have a greater impact on their lives and patience than on the aging of thermal sensations., kaken

• Grant-in-Aid for Scientific Research (C), 01 Apr. 2015 - 31 Mar. 2019, 15K00769, An intervention study on life skills for the elderly to prevent heatstroke, AZUMA Michiyo, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Kio University, 4550000, 3500000, 1050000, The present study assessed daily environmental regulation behavior, water intake, sleep quality, the thermal environment and skin temperature at home during the summer to identify life skills that could prevent heatstroke among elderly persons. We found that elderly persons tended to live in hotter and more humid environments than younger persons. Variations in skin temperature appeared to differ between young and elderly persons because of a decrease in the ability to regulate body temperature with age. In addition, sleep quality decreased among elderly persons who live in hot environments, indicating that environmental regulation needs to be improved among the elderly. Providing intervention in the form of physiological information about heatstroke prevention as well as tools for visualizing the thermal environment conferred some improvements. Changes in preventive awareness by interventions differed among individuals, suggesting a relationship with experience of heatstroke., kaken

• Grant-in-Aid for Young Scientists (B), 28 Apr. 2011 - 31 Mar. 2016, 23700873, Study on the life style of environment symbiotic in consideration of individual variation, SASSA Naomi, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Mukogawa Women's University, 3770000, 2900000, 870000, We are asked for the immediate action from aggravation of global environment. Many of life style of environment symbiotic until now were proposed for the average person. Since the individual difference of the comfortable temperature was large, it was thought that the difficulty of the doing of each life style of environment symbiotic were different. The purpose of this study is to investigate of the life style which is easy to tackle in consideration of the individual characteristic. I conducted examination and an artificial climate chamber experiment for the college student. Although the college students were interested in energy saving, the rate which they did not think concretely was high. Between the male and the woman, the ways of living which are easy to tackle differed. Between the sensitive to the cold and the sensitive to the heat, there were difference in their regulation method of the air temperature and the air current., kaken

• Grant-in-Aid for Scientific Research (C), 01 Apr. 2012 - 31 Mar. 2015, 24500934, A study on improvement in the living environment and daily living habits for the elderly to prevent heat disorders, AZUMA MICHIYO; OKAMOTO Keiko; SASSA Naomi; BAMBA Ikuko; KUBO Hiroko; ISODA Norio; TSUZUKI Kazuyo, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Kio University, 5330000, 4100000, 1230000, The purpose of this study was to investigate strategies to prevent heat disorders in the elderly. Data on the thermal environment collected automatically by thermal recording devices, and thermal sensation, thermal comfort, room temperature evaluation, acceptability, and activity were collected from young and elderly individuals in summer. Regarding physiological responses, skin temperature data were collected from some subjects. Furthermore, we conducted a questionnaire survey about knowledge of heat disorders, measures taken to prevent heat disorders, and daily living habits to analyze differences between generations. The results were given as feedback to each elderly individual and additional information about prevention of heat disorders was also offered after the investigations. Some advantages of these interventions were confirmed, but limitations were also identified. Strategies linked to preventive behaviors thus need to be considered along with technical knowledge., kaken

• Grant-in-Aid for Scientific Research (A), 2009 - 2012, 21240067, Study on optimal air conditioning environment in consideration of energy saving and individual resident's ability to adapt on thermal environment, ISODA Norio, Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research, Nara Women's University, 37440000, 28800000, 8640000, In order to clarify the optimal air-conditioning environment of a dwelling paying attention to energy saving and the ability to adapt of an individual, the measurement survey about a series of thermal environments and air quality environments of the houses was carried out. A series of adaptation-to-environment experiments and a experiment of air quality in the climate chamber were conducted. As a result, the thermal environment of the toilet and bathroom were low and poor in the winter in living environment, and the possibility of health impairment was suggested. The thermal environment of the eco-house and the half-basement was maintained more comfortably than other dwellings. Elderly people's healthy life has been maintained to some extent by carrying out heat insulation repair. On the other hand, we were anxious about aggravation of air environment. Moreover, the importance of control of order environment became clear. Furthermore, thermal comforts rose 1℃ in the summer when conscious of energy saving. We showed thermal adaptation properties of the elderly person and subjects who were poor at cold., kaken

• 若手研究(B), 2005 - 2007, 17700544, 温熱的特性に応じた快適な室内温熱環境に関する研究, 佐々 尚美, 日本学術振興会, 科学研究費助成事業, 武庫川女子大学, 2000000, 2000000, 提案されている室内温熱環境の快適範囲は、平均的な人や全体の約8割の人を対象とした範囲であり、残りの2割には高齢者や寒がり等の温熱的弱者が含まれると考えられ、この様な特性に応じた室内温熱環境を検討する必要性がある。そこで、本研究では暑がり・寒がりの好む室内温熱環境調節について検討する事を目的に、夏期と冬期に暑がり・寒がりである女子大学生を対象に人工気候室実験を実施した。
  実験は、夏服着用及び相対湿度50%は一定とした。夏期は気温を暑がりは29〜30℃、寒がりは28〜31℃の4条件とし、入室30分後に気流を自由に調節する「気流調節実験」と、気温32℃に設定の人工気候室に入室直後より気温と気流を60分間自由に調節する「自由環境調節実験」を実施した。冬期は入室時は気温15℃、不感気流とし、被験者位置にて30分後に黒球温度22±1℃となる距離に設置したストーブ、ファンヒーター、パネルヒーターのいずれかを30分間使用する「暖房器具実験」を実施した。測定項目は、気温や黒球温度等の室内温熱環境を、Hardy&DuBoisの12点等の皮膚温や舌下温等の生理的反応を、温冷感や快適感等の主観的反応とした。皮膚温と環境は30秒間隔、舌下温と主観申告は10分間隔にて測定した。被験者は夏期は9名、冬期は寒がり4名とした。
  その結果、「気流調節実験」では気温28、29℃では暑がりの方が約0.1m/s強い気流に調節し、「環境調節実験」では入室直後は暑がりの方が気温を下げ、寒がりの方が強い気流に調節し、60分後は暑がりの方が0.7℃気温は高くより強い気流に調節し、SET*で約1℃低くなり、暑がり寒がり別に好む環境調節は異なっていた。「暖房器具実験」では使用30分後の全身温冷感はいずれもほぼ同じであったが、末梢部皮膚温や快適感はストーブが最も高く、長時間使用や帰宅直後に最も使いたい暖房器具として評価された。, kaken
