Objectives: Little is known regarding the associations between Borg’s rating of perceived exertion (RPE), cardiopulmonary responses, and carrying bags while level walking. We investigated the changes in RPE and cardiopulmonary responses, including energy cost (EC), oxygen consumption (VdotO₂), and heart rate (HR), when walking with a bag. Methods: This randomized crossover study included 10 healthy adults (aged 21–22 years). Four days of experiments were performed at intervals of 1–2 weeks. The participants walked on a level treadmill while carrying a bag with a strap weighting 5 kg, placed diagonally on their shoulders (DS), vertically on their shoulders (VS), vertically in one hand (VH), and on their backs using both shoulders (BS) for 20 min. Walking speed was stable among all experiments, and was set to the participants’ preferred speed. Results: No significant differences between bag carrying methods regarding EC, VdotO₂, and %HRreserve (based on HR) were observed, whereas RPE respiratory (RPE-resp) and RPE leg muscle (RPE-leg) scores varied based on bag carrying method used. RPE-resp score was significantly lower for DS and BS than VH (both p < 0.0083); however, no significant difference was observed when each RPE-leg score was compared. Conclusions: We found that RPE-resp score varied, whereas no changes in EC, VdotO₂, and HR were observed in healthy adults while walking with different bag carrying methods. Additionally, of all bag carrying methods assessed, the highest RPE-resp score was observed when individuals carried a bag with one-hand at their side.

Honda, Ayumi,Abe, Yasuyo,Date, Yutaka,Honda, Sumihisa Occupational Safety and Health Research Institute 2015 Safety and health at work Vol.6 No.2

Background: There has been considerable interest in Japanese society in the problem of work-related stress leading to depressive symptoms, and an increasing number of primary houseworkers maintain paid employment. The purpose of this study was to examine the differential impact of multiple roles associated with psychological distress among Japanese workers. Methods: We studied 722 men and women aged 18-83 years in a cross-sectional study. The K10 questionnaire was used to examine psychological distress. Results: The proportion of participants with psychological distress was higher in women (17.8%) compared with men (11.5%). Having three roles significantly decreased the risk of psychological distress [women: odds ratio (OR), 0.37-fold; men: OR, 0.41] compared with only one role. In working married women, there was significantly less psychological distress (OR, 0.27), and those with childrearing or caregiving responsibilities for elderly parents had significantly less psychological distress (OR, 0.38) than those with only an employment role. Similarly, working married men who had childrearing or caregiving responsibilities for elderly parents had significantly less psychological distress (OR, 0.41) than those who had only an employment role. Conclusion: The present study demonstrated that participants who had only an employment role had an increased risk of psychological distress. The degree of psychological distress was not determined solely by the number of roles. It is important to have balance between work and family life to reduce role conflict and/or role submersion, which in turn may reduce the risk of psychological distress.

Work-related Stress, Caregiver Role, and Depressive Symptoms among Japanese Workers

Honda, Ayumi,Date, Yutaka,Abe, Yasuyo,Aoyagi, Kiyoshi,Honda, Sumihisa Occupational Safety and Health Research Institute 2014 Safety and health at work Vol.5 No.1

Background: In Japan, more than 60% of employees are reported to suffer from anxiety and stress. Consequently, Japanese society has begun to address such important issues as psychogenic disability and job-related suicide. Furthermore, given the aging of society and the surge in the number of elderly people requiring care, it is necessary to adequately and proactively support employees who care for their elderly relatives. The purpose of the present study was to investigate caregiver burden in caring for elderly relatives and work-related stress factors associated with mental health among employees. Methods: We studied 722 men and women aged 18-83 years in a cross-sectional study. The K10 questionnaire was used to examine mental health status. Results: The proportion of participants with a high K10 score was 15% (n = 106). Having little conversation with their supervisor and/or coworkers significantly increased the risk of depression [odds ratio (OR) 1.8], as did high job overload (OR 2.7) and job dissatisfaction (OR 3.8), compared with employees who frequently conversed with their supervisor and/or coworkers. Caring for elderly relatives as a prominent characteristic of an employee was a significant risk factor for depression (OR 2.1). Conclusion: The present study demonstrated that employees who were caring for elderly relatives were significantly associated with an increased risk of depression. To prevent depressive disorders, it may be important to focus on reducing the work-caregiving role conflict, as well as enhancing employees' job control and better rewarding their efforts in the workplace.

Takuya Honda,Nobutomo Matsunaga,Hiroshi Okajima 제어로봇시스템학회 2019 제어로봇시스템학회 국제학술대회 논문집 Vol.2019 No.10

The modeling of driving behaviors is important to analyze and design comfortable functions for the driving systems. The estimation method of the non-linear steering model using the eye tracking information was studied using the heuristic search algorithm. However, the model was limited to gaze and the inattentive driving was not modeled. It is considered that the steering model is consists of a hybrid steering model that switches the controllers according to the eye tracking information is classified in the effective/peripheral viewing field. In this paper, an estimation method of the hybrid system focusing on the effective visual field during driving is proposed. The hybrid model is constructed by steering model depending on the gazing distance and simple on-off controller. This estimation algorithm consists of 2-steps; clustering which classifies data by k-means method and the estimation of the parameters by Particle Swarm Optimization. The experiment with the long driving course consisting of five-curves and straight lines is demonstrated by HONDA driving simulator.

Honda, Yoshiaki,Kajiwara, Koji,Yamamoto, Hirokazu 대한원격탐사학회 1997 International Symposium on Remote Sensing Vol.13 No.1

It is necessary to use the ground observational data to cadculate physical value in a wide survey unit (1km×1km) in order to verify the reliability of the algorithm for speculating physical variable from lkm satellite data. Since it is difficult to conduct the ground observation within whole wide area survey unit in short time, the minimal survey area which can represent a wide survey unit has to be determined. The objective of this study is to find the minimal representing area of a wide survey unit through the car survey and radio-controlled helicopter survey we developed in Mongolian grassland. As a result, it can be said that these systems used in the research are a good way to calculate the minimal representing area of a wide survey unit.

多人数クラスにおける日本語会話教育の実践方法 -韓国の大学における教養科目としての日本語教育を中心として-

Honda Miho 한국일본어학회 2009 日本語學硏究 Vol.0 No.26

韓国の大学における教養科目としての日本語の授業(以下、教養日本語と呼ぶ)は、一般に大教室で多人数を対象に行われるため、すべての学習者を巻き込んで授業を行うのは容易ではない。また、学習者は、日本文化への関心が高い者が多いが、それが直接学習意欲に結び付いているとは言い難い。 本研究は、意欲の高さを前提としにくい多人数の学習者に対する一斉授業という不利な条件を克服して、学習者間、及び学習者と教師間においてより実際の場面に近いコミュニケーションが活発に行われる会話授業を展開するために授業の観察結果と学習者の事後評価に基づいて素材と活動方式を見出すことを目的とする。 実践では、学習者世代の関心に応える語彙の使用、目標を明示的に提示し達成感を得させる活動、グループ単位での会話練習と日本人教師との直接対話という系統的構成を行った。これにより授業を円滑に展開することができ、ほとんどの学習者が事後評価において日本語への関心の高まりと学習継続への意欲を報告した。本実践で用いた方法が、「教養日本語」の制約の下で有意義な会話授業を展開するために有効である可能性が示唆された。
