• 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 基盤研究(C), 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 (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 Grant-in-Aid for Scientific Research (C), 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

Nasal region of healthy subjects was exposed to non-odorant, plywood, and cedar timbers that dehydration temperature and/or production region were different. Regional cerebral blood flow (rCBF) in prefrontal cortex and electroencephalogram (EEG) were simultaneously measured. Result indicated the activation of rCBF significantly increased in plywood that emission of formaldehyde were the highest. The result suggested the plywood acted as irritation to nose of the subjects. Cedar timber that were produced at middle dehydration temperature rather than lower and higher temperature, showed good responses in human brain imaging both rCBF and EEG. This suggests the subjects received irritation and discomfort from timber of lower dehydration temperature because the emission of total volatile organic compound was the highest at natural air-dried timber., kaken_url

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_url

For an objective approach for evaluating thermal sensation, we attempted to develop a suitable protocol for one of brain imaging techniques, fNIRS (functional Near Infrared Spectroscopy). The developed periodic thermal stimulation clearly modulates thermal sensation. We confirmed that the stimulation of Aδfibers combined with menthol administration enhanced brain activity estimated by EEG (electroencephalography) and that thermal sensation during the periodic thermal stimulation was further evoked by menthol., kaken_url

The research findings are as follows:
  1. The household structures in Bamyan are classified into there categories: the nuclear family, the joint family and the compound household. The overall system is basically patrilineal and patrilocal. Nuclear families maintain an extended kinship network in the community. The family system is basically patrilinial and patrilocal.
  2. There are two main social groups in Bamyan, the Hazaras and the Sayyeds, between which there are wide social, economic and cultural disparities.
  3. Strategies in child education in family differ by both social groups and gender. School attendance rate are lower for The Hazaras than for the Sayyeds, and lower for girls than for boys.
  4. There is clear gender segregation and role division. Because the infrastructure is not yet developed in Bamyan, there is a great deal of housework for women and children, especially daughters.
  5. Afghan Refugees in Iran form Afghan communities to minimize discrimination from Iranians.
  6. Though Afghan refugees in Iran have restricted access to work and education, their living standards are higher than those of Afghanistan.
  7. The Iranian government has been promoting a repatriation policy for Afghan refugees, while increasing economic supports to Afghans.
  8. The Iranian government has been restricting the schools for Afghan refugees, so that they are forced to close and move. Since the schools do not get any support, they face difficult problems.
  9. Afghans' experiences of living in Iran make change their concept of education and gender, so that their return to Afghanistan would affect an improvement of the educational situation in Afghanistan. But for it, it is essentially prerequisite to ensure peace and security, economic independence, and to improve living standards., kaken

We carried out two experiments in a climate chamber as follows. Experiment 1: the direct determination of preferred air temperature. The subjects regulated air temperature for 120 minutes. We explained individual variations of thermal comfort for the elderly, and whether it's a good condition for the elderly health. During the experiments, we measured the skin temperatures, heart rate, thermal comfort vote, thermal sensation vote, and so on. And, we measured metabolic rate and heat loss, and we considered heat balance under several thermal environment. The subjects were 30 healthy elderly women. The subjects sat on a chair during the experiments in summer clothes (0.4clo). Experiment 2: exposure to established air temperature (23℃, 25℃, 31℃, 33℃). The subjects were exposed to established air temperature for 60 minutes. We explained the effect of established thermal environment on physiological and psychological responses. On Experiment 2, 19 subjects were extracted from Experiment 1. By these experiments, we determine an extant of comfort temperatures for the elderly that has several preferred temperatures in summer. The results were as follows;
  Preferred air temperature were from 24.4℃ to 29.3℃. The average of preferred air temperature was 27℃, and standard deviation of mat was 1.3℃. On that conditions, almost subjects voted 'comfortable'-'very comfortable'. But under 25℃, some elderly cooled their core temperatures a little, and their heart rate declined. This indicates that the elderly decrease in ability to control the skin temperature., kaken

In our investigation, we principally conducted oral interviews and observation in house visits, and made photographic records.
  In conducting investigations, we were divided into groups according to each one's specialty, such as families, genders, cloth-ing, dietary culture, and living environments. In order to comprehend the situation of the region, we invited the cooperation of teachers of secondary school and Xinjian University, instructors of museums and foreign students of Uygur people.
  We report about the following contents of our investigation about which we have formed a viewpoint.
  1)Children's education 2)Ordinary lives and Religious lives like Ramadan 3)Expression of costumes as Muslim 4)Traditional customs and their changes in Family relations and lives.
  Main problems of school-education are that the high school attendance rate has declined and that students who are not able to go to school have been increased. In particular, among the poor farmers' households that account for 80% of the region, parents do not have higher expectations for their children, thus they prevent their children from going to school.
  Their main agent of child-rearing is the mother. Mothers raise children by receiving sufficient support from relatives, especially their own mothers.
  Uygur people maintain the culture of gender division of domestic labor. Particularly Muslims maintain a strong patriarchal system so that their educational expectations for daughters are lower compared to sons., kaken

We aimed to conduct investigations on the actual conditions of Uygur women and their lives. Because the population of Uygur people is the largest among the forty-seven minor ethnic groups in the region. In conducting investigations, we were divided into groups according to each one's specialty, such as families, gender, clothing, dietary culture and living environments, and we decided to compare a city and its surrounding area (a rural community), tradition and changes, and South Xinjiang and North Xinjiang. In order to comprehend the situation of the region, we invited the cooperation of researchers in the Center for Research on Women at Xinjiang University as our counterparts.
  In 2000, we visited Urumchi and Turfan, and investigated the roles of the female staff of educational organizations, differences in the lives among typical ethnic groups, the labor of women who engaged in traditional industries, their tasks at home. In 2001, we visited Kashgar and Hotan, recorded the conditions of deeply religious lives connected with Islamic culture, and conducted a study on them. In 2002, in order to compare lives in South Xinjiang and North Xinjiang, we visited Yining, adjacent to Russia (the former Soviet Union) and investigated mostly farmers' lives. As a result, we witnessed remarkable affluence due to trade with Russia and other regions, and westernized freedom for various aspects, of then-lives, such as their home interiors and preferences for doming, unlike South Xinjiang. As the results of our comparison between the city and its surrounding area, and South Xinjiang and North Xinjiang, it was learned that close family relations common among Uygur people continued, but religious characteristics changed drastically in some regions. There were also problems, such as difficulty in the coexistence of international aspects with ethnical aspects., kaken

For this purpose, we conducted the survey on residential thermal environments for the elderly people and the experiment on ifluences of thermal environment on physiological and psychological responses in the elderly subjects in climate chamber. In a questionnaire survey on residential thermal environments, the most popular cooling system were the air conditioners, and electric fans among the elderly people who were over 60 years old in summer. In winter, the heating mechanism most commonly used was stove among the elderly people. In the measurements of residential thermal environments in the elderly people residences, the mean room-air-temperatures (Ta) were 27C-29C in summer. In winter, Ta were 15ﾟC-18ﾟC at living-room and about 8ﾟC at bed-room. In the experiments of climate chamber, the skin temperature at the chest (trunk) of the elderly was lower and dropped greater than the young subjects in the same air temperature. But the drop of the elderly's skin temperature at the shin was smaller than that of the younger groups in summer. These suggest than the special attention should be required for an room temperatures to be adjusted properly and comfortably for the elderly. We recommend room-temperature of 26ﾟC-29ﾟC in summer and 21ﾟC-25ﾟC in winter with the radiant heating system at the floor., kaken

  We payd special attention to air velocity and sorts in summer, and to warming of the bed in winter.
  The results are as follows.
  1. In Summer, at ambient temperature 30ﾟC,exposure forehead or leg to a weak air current (0.4m/sec) intensified the degree of rectal temperature fall. Under this condition, the sweating was suppressed and body temperature was controlled mainly by dry heat loss.
  2. An effective exposure site to air flow was the forehead in comparison with the leg to induce deep sleep. As for the sort of air flow, moreover, the cyclical flactuating air velocity was more effective for deep sleep without falling leg skin temperature than the uniformed air velocity.
  3. In winter, warming the bed in advance facilitated the rise in leg skin temperature and deep sleep was maintained all night long., kaken
