    　View Summary

    <p>This experiment tested the effectiveness of pain relief patches using a human factors engineering method. It is said that sticking pain relief patches on the plantar arch of the foot can help reduce fatigue around the hips and knees. Measurements for this study involved the evaluation of the static upright postures of 8 female participants. I got the subject to measure blood pressure and cardiac beats rate. Moreover, the Visual Analog scale questionnaire survey was conducted. Data were collected a total of four times per person, both before and after exercising with and without the pain relief patches. The eye-opening state and the eyelid closure state were added, respectively. Since it measured by eight patterns, 64 data was collected. While there were no effects observed before exercising for both conditions. There were no significant difference in area between Center of pressure (COP) measurements during the static upright postures in an eyes-open state after conducting the exercises with and without the pain relief patches. Consequently all participants reported that they did not feel the pain relief patches on their feet. The results of this experiment support the fatigue-alleviating effects of the pain relief patches and suggest its possibility in maintaining a more stable static upright posture. It was considered that post physical activity, due to decreasing the trajectory of COP, it was effect of possibility anti-fatigue function..</p>

    　View Summary

    Fall accident is one of the problems in aged society. And Joint disease is also severe, especially in the field of rehabilitation. They are related to the walking ability. Thus, the evaluation and training of walking ability are important to prevent fall accidents. Conventionally, it needs long term of experiments to evaluate the walking ability by motion capture systems, force plates, and so on. In addition, the conventional methods spend costs expensively. The evaluation should be obtained easily in order to reduce the subjects’ burden. In this study, evaluation by the accelerometer and gyrometer was practiced in place of the conventional methods. Two 8ch acceleration and gyro sensors (RF10, MicroStone Corporation) were installed to a subject’s sacrum and vertebra to measure his spine stick picture motion during his walking. Power spectrum, movement track and RMS were used for comparison with measurements of motion capture system (Vicon). All the results have shown the validity and reliability of the simple measurement method. It was revealed that the stick picture motion has the possibility to be applied to the walking ability indicator.

    　View Summary

    It is one of the most important to create an optimal sleep environment. People who lived irregular hours, i.e. shift workers, global communication tasks, typically obtain 1–2 hour less sleep than the generally accepted target of 8 hours per day. Shift work has become increasingly common in the modern globalized economy. Many work settings such as factory work, service industries, power plants, internet communication management, health care and emergency services require shift work that includes work at night. Furthermore, not only shift workers but also young smart phone device users often experience an extended period of acute sleep deprivation at the start of a new day. Most sleep deprivation studies using complex cognitive tasks require the participants to complete the tasks alone. It was effected human health care and learning performance in young people. The purpose of the current study was to investigate how sleep environment changes between high school student and university student. Jissen Womenn’s Uiversity Ethics Committee approved this survey. There were 831 students (male: 387, female: 444) participate in this study. It was 16 sleep questionnaire items on our web server, i.e.: depth of sleep, difficulties in waking up, quality and latency of sleep, negative affect in dreams, and sleep irregularity, etc. It was collected data during our course activity. There was no significant difference sleeping pattern in between high school and university student. Additionally it was on roughly the same level sleeping conditions of them. However it was a tendency toward to sleep deprivation onto nocturnal life. In the current report we present results of a prospective study that used objective measures to evaluate sleep, it was consequently sluggishness due to the chronic sleep deprivation, to become a late-night students.

  • Quantitative confirmation of residents’ everyday life behavior by acceleration measurement of facilities in a house

    Macky Kato, Yoshie Shimodaira, Takeshi Sato

    New Ergonomics Perspective - Selected Papers of the 10th Pan-Pacific Conference on Ergonomics     243 - 249  2015

    　View Summary

    In aged society, decreasing of worker population is one of the most important problems. Especially the farming population has been decreasing in recent years. On the other hand, the elderly people’s families live away from them, because they cannot expect a reasonable profit from farming. In addition, it is hard to find other jobs in a rural area. Thus, the isolated farmers need somebody’s help to take care of themselves. For example, the families can confirm their everyday lives by a remote system with monitor cameras. However, it can violate the residents’ privacy. The appropriate system should have a confirmation function without violating the privacy. In this study, facilities in a house can be thought as sensors of everyday life in place of cameras. The acceleration measurement was held for quantification of the residents’ behavior in a house. The residents in the subject house are 62-year aged husband, 58-year aged wife and 91-year aged father. The accelerometers have been fixed on the refrigerator and the door in the house. Approximately one-year lengths, acceleration of the facilities were recorded through 2013 and 2014. The fluctuation of acceleration of the refrigerator can indicate the resident’s using in a day. It showed that the residents lived well-regulated lives. The refrigerator will be able to indicate the feature of their everyday life. On the other hand, the fluctuation of acceleration of the door can indicate the resident’s movements inside out. The door movements depend on the seasons. The number of the door movements in each season is different. They kept the door open through the daylight in summer, but they close the door after going in winter. These results reveal that the acceleration measurement of facilities in a house can become the quantitative confirmation method of residents’ everyday life stability.

    　View Summary

    Motion repeatability is one of the required skills for any sports including tennis. One of the reasons why expert tennis players can accurately serve the ball to another side is their motion repeatability. On the other hand, however the novice players can luckily serve the ball, they are required to practice again and again to repeat the motion. The reliable criterion by the objective numerical indicator is needed for training and evaluation of motion repeatability. In this study, the method of numerical evaluation of motion repeatability would be developed by a motion capture system. The correlation coefficients of each segment angular fluctuation on the serving motions were validated as the criterion for motion repeatability. 17 sensors measure three-dimensional 23 segments and 22 joints angle fluctuations during the two seconds around the ball impact. Three experienced tennis players and three novice players tried to serve ten balls by right arms. The results of the experiments indicated that the repeatability of upper body tends to be stable comparing arms and legs for all the subjects. The correlation coefficients of the fluctuations at the measurement joints that are far from the upper body tend to be low. Comparing the experts and the novices on the motion of the arms and legs, the novices have much variation of correlation coefficients of each motion than the experts. In addition, most of the motion fluctuations of novices are larger than those of the experts. This study revealed that the joint angular fluctuation would be able to be applied as a criterion of motion repeatability.

  • Simplification and transformation of ASTM F1292 measurement procedure for fall accident injury criteria

    　View Summary

    Protecting children from injuries caused by fall accidents from playground equipment is important. Therefore, measures toward minimizing the risk of fall accident injuries are required. The risk of injury can be evaluated using ASTM F1292. In this test, G-max and the HIC are used to estimate the risk of injury. However, the measurement procedure is too complicated for application to a large number of installed equipment. F1292 requires simplified by reducing the number of phases, even with a small risk of loss in accuracy. With this in mind, this study proposes a shortened measurement procedure and a transformation equation to estimate the risk as same as F1292. As the result of experiments, it was revealed that G-max and the HIC values for both procedures linearly increase with drop height. The differences in outcomes between the regression equations of the standardized procedure and those of the shortened procedure can be used as a correction value. They can be added to the value measured by the shortened procedure. This suggests that the combination of the shortened procedure and transformation equation would be equivalent to F1292, with the advantage of being more easily and efficiently applied to the evaluation of installed playground equipment.

And it was too quickly eye gaze movement to detected difference. The other it was equal time and trajectory on right and left stimulus picture. © 2012 IADIS.

  • Elderly people's health confirming by measurement of fixtures acceleration

    Macky Kato, Yoshie Shimodaira, Takeshi Sato

    　View Summary

    The numbers of the elderly people who live alone have been increasing in Japanese society. One of the countermeasures against solitary elderly people's problems is the development of a safety confirming system. Past studies indicated that measurement of acceleration on fixtures at home may be able to become a method to confirm the solitary elderly person's condition at their home. However the acceleration measurement at multiple positions in the house may be applied not only as a safety confirming method, but also as a health confirming method. In brief, the rhythm observed in the acceleration variation may indicate the inhabitant's usual behavior rhythm. The results of a month-long record of six fixtures indicated that subjects have their own behavior rhythm on each day. When some irregular wave was recorded out of their rhythm, we can suppose that some irregular "event" has occurred. For example, the variation of bedroom door acceleration indicates the subject's behavior through the night. When no acceleration was observed at the time to go to bed, the subject did not use the bedroom, but had dozed off in the living room in spite of risk of cold. Also there were other flat lines through the measurement period. Those flat lines meant the subject's absence of movement. These facts mean that we can confirm elderly peoples' behavior, health condition and safety by measurement of acceleration of fixtures. © 2012 IADIS.

  • Comparison of postural control ability among three age groups using acceleration measurement

    Macky Kato, Yoshie Shimodaira, Takeshi Sato

    Journal of human ergology   40 ( 1-2 ) 101 - 108  2011.12

    　View Summary

    The purpose of this study is to suggest a numerical model for postural control ability variations in children, young adults and the elderlies. Three sensors were attached to the subjects' bodies at the vertex, the iliospinale and the mid-patellar to measure three-dimensional acceleration at each point while subjects maintained a standing posture for two minutes. Variations in acceleration at the vertex differed among the three age groups. Most children subjects could not maintain the initial position during the trials, whereas the young adult subjects could maintain it. Most elderly subjects could maintain their lateral balance however it was difficult for them to maintain their anteroposterior balance. From the results of acceleration measurement, it is indicated that the scalar of the average acceleration vector at the vertex point could serve as a numerical criterion of postural control ability.

    Number of elderly people who live alone or elderly only couples are going to increase as ratio of elderly people increase in Japan as same as the other developed countries. They often have trouble with their health which needs care by someone. However most of their families live away from them. In this study we tried to develop remote monitoring system by measurement of fixture movement at home to observe the elderly people's daily behavior for safety. Through eight days experiment at rural area in Nagano, Japan, the acceleration measurement system recorded the door movement to observe the inhabitant's characteristics. Extracted characteristics from the results has shown the inhabitant's behavior which can be used for criteria of their activities. Elderly people who live alone or elderly only couples will be able to be monitored their safety by this automatic confirming system without violation of the inhabitant's privacy. © 2011 IADIS.

    平成19年度から20年度にかけて実施された入力に関するインターフェイスとして用いる新規デバイスに関する研究の結果、入力方法の簡素化が必要であることがわかったため、インターネット接続用の機器として安価に入手できる携帯型ゲーム機に用いられるインターフェイスによるWEBブラウザ利用を試みた。操作すべき対象の数は減るため、学習に要するユーザの労力は低減する。しかしながら小型のブラウザ機器は画面の大きさが小さく、利用に困難が生じるため、表示機能との間でトレードオフが生じることが明らかとなったことから、表示を拡大する必要があることが明らかとなった。
    また、入力側インターフェイスの構造に対して、平成21年度は、出力インターフェイスを課題とした寛容性の研究を行った。すなわち、前年度までの調査によって、高齢者に対する操作性向上を目的とした機能制限は,インターフェイスレベルにおいて必要であることがわかったため、特にコンピュータによる表示情報についての寛容性を実現するために、専門的に用いられる用語を普通の態様で使用される言葉への置き換えについて検討した。初心者向けに用意された教本から抽出した用語の多くは専門用語を用いているが、これを普通に用いられる言葉に置き換えることで、ユーザの理解を促すことが可能になることがわかった。つまり実装されるインターフェイスとして、ユーザ自身が持つボキャブラリへの変換が行われることが、表示デバイスに求められることがわかった。以上のことから、PCの用途を限定している多くの高齢者ユーザに対してPCの利用促進にあたっては、複雑な学習を要するPCではなく、高齢者のユーザ特性を考慮し、機能が限定された安価な端末を用いる方法が、寛容なPC学習方法として有効であるといえる。

    　View Summary

    One of the purposes of this study is decreasing residents' physical and mental burden in a depopulated area by applying IT to Mura-Yaku, the role of the village, by introducing information and communication technology. Another purpose is preparing the computer environment at elderly people's house as communication tools for their hobby, farm and communication for their family who stay away.
    At first, we held PC class with aim of applying information technology to Mura-Yaku, the role of village. However, we had only suggested the alternation of Mura-Ysku to the IT at that time, because of the little number of participants in small area and the problem of infrastructure in the village. It was cleared that expanding number of users is important for the computerization. Mura-Yaku will be changed into information technology when they use PC without any limitation.
    In order for the elderly people to continue using PC at their house after the lessons, they need some support systems. By the support system and assist of a computer club in the neighbor village, we came to send tutor to them from community center. On the other hand, we started Nakajo PC Cub for the students of computer class to communicate each other and get some help of supporters. We opened the permanent computer room at the community center to expand the number of users and to support them to use IT. Furthermore, we conducted an experiment of pointing device manipulating by elderly users and could find out a factor of device for elderly users.
    The purpose of PC was for use as a stand-alone until this time. So we held the next PC classes to build homepages with the consciousness of use in network. At this time the staff of community center and village office participated with the residents. Most of their concerns are about their personal materials, such as hobby, farm, and so on. Thus, it will become possible to activate the communication outside a village by dispatching their personal information. This resident network was able to show the direction which agriculture and depopulated area activate.

    In this study, Mura-Yaku is paid attention, which has been the role to manage the community for many years. However, it is felt as burden for the residents in the depopulated aged area. The purpose of this study is applying IT and proposing an effective model to reduce the burden. Some of case study for novice elderly users of PC was proposed in 2003. And in 2004, the problems were clarified for the aged students using PC continuously at their home. Although PC was used for a while at the house, it will not be used when agricultural work becomes busy. Therefore, some of them forgot that basic operation task. And there was a case that frequency of communication with their family by the E-mail decreased gradually. Thus, use frequency also decreased. Although they can ask to the researchers when they have trouble, they hesitated to ask. Consequently, there were students who call the researchers after long time, and students who stop using after the trouble.
    The charge of the Internet use was expensive for elderly people to connect, even if they know the convenience. Continuation uses of PC by the elderly people needs improvement of the interface such as language, their own purpose to use PC, and keeping of troubleshooters.
    At the 2nd class, staff of a public hall was positioned as a supporter. Moreover, PC room was prepared continuously to be able to contribute to the improvement in the rate of PC use. Attendances also want to use PC for Mura-Yaku positively. As a result of this study, the model of the local management system was established, which replaces Mura-Yaku and be applied in a depopulated aged area.

    本研究の目的は介護従事者に対する情報提供のために携帯情報端末を有効利用することであるが,平成16年度は前年度まで行ってきた,利用の前提となるインターフェイスの適正化が必要である点に関して継続的な研究を行った.特に端末のユーザのニーズに対して適切な情報を提供するためには,ユーザのニーズを明確化する必要があるため,携帯情報端末を継続的にモニタリングする介護従事者に対する直接的な聞き取り調査を行ったところ,ユーザが求める情報のうちもっとも優先順位が高いものは,介護対象となる要介護者の個人情報であった.聞き取り調査および質問紙調査においても同様の結果がえられたことから,これを可能にするシステムの導入が求められていることがわかった.ただ単純なイシターフェイスを具備した携帯情報端末に対して個人情報を提示することは,その保護の観点から望ましくないため,十分なセキュリティが必要となる.そこで簡素なインターフェイスとしてバイオメトリック認証技術などの導入が必要であることがわかった.
    質問紙調査では,PDAの普及については低迷していることがわかった.対象となった104名のうち約89%が携帯電話を所有していたが,PDAについては約3%であった.さらに携帯電話所有者のうち約87%は電子メールを利用しており,テキスト形式の情報の取り扱いについて可能であることが示唆された.PDAの普及が進まない原因は2点あげられる.一つはPDAを用いることによる仕事上の利点に関して知識がないことであり,もう一つは携帯電話の高性能化と普及率の拡大である.このことから,介護従事者に対して携帯性の高い情報端末を普及させるための用件として,ユーザビリティの向上に加えて,外部との通信機能の確保があることがわかった.従って今後の展開として,一層の効果的な情報提供を図るため,携帯電話のPDA化とユーザビリティの向上を検討する.

  • 交通弱者の優先性を実質化するトラフィックヒエラルキーにかかる研究

    2023  

    　View Summary

    混合交通の発生する道路上において，歩行者，自転車，自動車どうしの交通事故が発生する危険があることから，いわゆる交通弱者（歩行者，自転車）の安全のため，優先性の確保が求められており，諸外国では法律または慣習によって一定の優先性が確保されている．この優先性をトラフィックヒエラルキーといい，我が国では道交法38 条に規定されている．日本自動車連盟が2016年より継続している，無信号横断歩道における歩行者の優先にかかる調査で，歩行者の横断に対して一時停止する車両は１割程度だったが，2023年には4割以上にまで改善されてきたことがわかっている．　本研究課題では自動車と交通弱者の立場から横断歩道における進行または横断の判断に影響をおよぼす要因についてとりあげ，そのうち交通弱者としての自転車の走行における車両との関連性について検討した．実験の結果自転車による危険運転として車両と路側帯との間のすり抜け行動における特性として，自転車の幅と通過する間隙との間に一定の比率が認められたことから，接触を回避するための自転車側ならびに自動車側のリスク評価にかかる基礎資料を構築した．左側通行が義務づけられている自転車の直進を妨げる駐車車両があった場合の回避行動の前提として必要となる自転車の後方確認動作の実験的な評価を実施し，目視確認とともにミラーによる後方確認の有効性を示すとともに，自転車の挙動特性を定量的に示したことで，自動車側から見た前方左側を走行する自転車の回避運動特性を示すことで，ドライバの危険予測に寄与する基礎的な資料が構築された．

  • 交通弱者の優先性を実質化するトラフィックヒエラルキーにかかる研究

    2022  

    　View Summary

    横断歩道におけるドライバーと歩行者の判断にかかるWeb調査を実施した．その結果，歩行者の立つ位置と人数によりドライバーが歩行者を優先する確率に差が生じることがわかった．すなわち自車に対して対向車線側に立つ場合と左右に立つ場合は一時停止の割合が低下し，徐行の割合が増えた．自車前後に車両がいる場合は単独走行と比べて一時停止の割合が低下し，徐行の割合が増えた．歩行者が横断判断に対して接近する車両の距離の把握が横断決定に影響する．車両の左右からの接近方向の差は小さいが複数台の接近時は横断しない割合が増えた．また車両停止時の歩行者横断ではドライバーに対して会釈，挙手などの意思表示が認められた．

    自転車は，自動車に対しては交通弱者であるが，歩行者に対しては交通強者であるため，大学生を実験参加者として自転車シミュレータ運転を行った．特に外部刺激に対する認知能力が低下する高齢者が歩行者や障害物に対して示す挙動を計測するために，高齢者を模した身体機能および認知機能を制限する装具を装着した状態で自転車を運転し，特に安全確認に要する時間が長くなることが明らかになった．また交通法規の法律遵守にかかる国際比較に関連して，歩行者優先を含む各国の道路標識に対する知識の有無について予備的な調査を行い，一定の標識については認識の過誤が認められたことから，改善または教育を要することが明らかになった．

  • 無信号横断歩道の歩行者安全を確保するトラフィックヒエラルキーの導入にかかる研 究

    2020   友野貴之

    　View Summary

    　無信号横断歩道通過時のドライバーの運転行動に着目し,要因をSHEL モデルに当て嵌め,無信号横断歩道における 歩行者優先の原則に対するドライバーの運転行動を定量的に示す研究を実施した．その結果，交差点構􏰀は譲る割合について有意差が示された.また天候条件と時間条件は 運転行動に影響を与えていた一方で,譲る割合に影響がなかった.視認性の低下は構􏰀による影響が大きい．譲る割合に影響がない 一方で,運転行動に影響を与えていた．大学生被験者と教官被験者の間で譲る割合に差が認められた．ブレーキ回数について大学生間では有意差が認められた一方,教官被験者には差がないなど,教官被験者は無信号交差点でも停止行動に一定の安定性があると考えられる.

    2015   下平佳江

    　View Summary

    前年度にひきつづき，高齢化率が高く，また公共交通機関が乏しい地域として長野県長野市住良木の農家を研究対象として生活様式の観察および測定にかかる研究を行った．ひずみゲージを用いた家具および建具の挙動により生じる加速度測定におけるキャリブレーションを正確に取得する初期設定作業についてはある程度の時間的，技術的な制約が加わったが，モニタリングにあたっては十分な出力を得ることが可能となった．前年度に指摘を受けた定量的指標の構築にあたり，上記センサーの出力の時系列変化に対して経営工学における管理図表モデルを適用させることで，日常生活におけるリズムの抽出と逸脱状態の検出が可能となった．

  • 独居高齢者等の日常生活行動を評価する生活支援機能を有する住居構造に関する研究

    昨今の高齢化により，特に中山間地などの過疎地域では高齢者のみの世帯や独居高齢者の割合が増加しており，日常生活における事故や疾患が懸念される．一方，子ども世帯等の同居は経済的理由等により困難であることから，遠隔の家族が建具と家具の使用状況を加速度センサによりモニタリングするシステムを構築する研究を行った．当該年度は既存データと新規データを合わせた年間活動記録を分析することで突発的自体の抽出アルゴリズムを構築した．また従来用いた有線のひずみゲージによるセンサから無線方式の簡易なセンサとPCに切り替え，その有効性を検討した結果，従来比で1/4程度の低コスト化とシステムの占有空間の削減を可能にした．

  • 独居高齢者の生活状況を評価する機能を有する住居構造に関する研究

    2013  

    　View Summary

    　遠隔地に居住する家族の生活状況をモニタリングは高齢社会においてニーズが高い．本研究では，日常生活のリズムを定量化する手法を構築することを目的とする研究を行った．長野市西部の中条地区の農家の協力を得て，特に住居の建具および家具に着目し，外出時に使用する頻度が高い縁側の出入り口と，冷蔵庫の扉に加速度計をとりつけた．2013年9月より2014年2月まで継続的に測定を行い，その変動波形に対する解析を行った．　出入り口の測定では，人の移動が多いことから，開閉動作だけでなく，人の通過により生じる振動も敏感に反応するため，活動量を評価するのに適している．ただ9月頃の暑い時期と1月,2月等の寒い時期とでは扉の開閉頻度が異なる．冷房設備がないことから，夏季は出入り口の扉は開けたままにされ，冬季は出入りするたびに開閉を伴うことから，日常生活の季節間変動があると推察される．また，居住者や来客等の区別は困難であるが，活動があること自体が日常的なことであり，これを定量的に示すことが可能となった．一方で午前0時近辺より朝4時くらいまでは振動が計測されず，睡眠時間帯であると推察できる．　家具として用いた冷蔵庫の扉については，6時前後，12時前後，19時前後に振動発生頻度が高い．これはつまり食事の時間帯にほぼ恒常的に冷蔵庫を用いていることを示している．出入り口の場合が比較的ランダムな人の出入りを測定しているのに対して，冷蔵庫の場合は夫婦のうち，妻の側が使用する頻度が高く，その日常的な使用状況から，特定の対象者の日常生活のリズムを示す指標として有効であることが示された。この点からは，居住者が複数名いる場合，個別の生活状況を評価するためには，居住者個人の行動特性を明確化させることが望ましい．　今後，継続的な測定により年間を通じた特性の抽出をすることで，通年で用いることができる，定量的な日常生活リズムの評価ができると思われる．
