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, Yutaro,Kaneko, Masanobu Korean Mathematical Society 2012 대한수학회보 Vol.49 No.6

We prove a congruence modulo a prime of Fourier coefficients of several meromorphic modular forms of low weights. We prove the result by establishing a generalization of a theorem of Garthwaite.

School urinary screening program in Japan: history, outcomes, perspectives

Honda Masataka,Yanagihara Takeshi,Gotoh Yoshimitsu 대한신장학회 2024 Kidney Research and Clinical Practice Vol.43 No.3

In Japan, pediatric urinary screening in schools for asymptomatic hematuria and proteinuria began in 1974 and has been very successful in detecting asymptomatic kidney diseases at an early stage. While the American Academy of Pediatrics recommended discontinuing urinalysis as a public health service in 2007, urinary screening in Japan has proven extremely successful in reducing the incidence of kidney failure with replacement therapy in children and young adults, especially through the early treatment of glomerulonephritis, such as immunoglobulin A nephropathy. Furthermore, the positivity rate on urinary screening in Japan is significantly lower than in the United States where the rate of false positive results is typically very high. Japan’s seamless and efficient pediatric urinary screening may be a helpful example for other countries as well. However, the present investigation revealed several, unresolved problems with the system. For example, the methods used varied in terms of their cutoff point, additional examinations, and types of detailed testing. In Japan, various urinary screening methods are being tested to optimize the system for national use. Recently, the authors also recommended a system of detailed examinations, including beta-2 microglobulin testing and ultrasonography, to detect congenital anomalies of the kidney and urinary tract, the most common, underlying disease in kidney failure with replacement therapy, which is often overlooked until the symptoms have become grave. While school urinary screening has been ongoing for about 50 years and should be continued, improvements should also be made to it as needed.

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.

The Impact of Multiple Roles on Psychological Distress among Japanese Workers

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.

日本との交流が活発化し、相互への関心が高まってきた今日、質の高い教育を実施できる母語話者日本語教師(以下母語話者教師を呼ぶ)が求められている。本研究の最終目標は、今後重点的に養成すべき教師の能力を発見し、質の高い教師の養成に必要な教育の方法を探ることである。そのために、韓国における質の高い母語話者教師とはどのような教師であるのかを明らかにする必要がある。その手段として、韓国の大学、特に四年制大学に注目し、韓国人教師、学習者さらに母語話者教師自身に調査を行い、包括的なデータによって韓国の4年制大学が求める母語話者教師の役割及び能力を分析していく。本稿では、韓国の教育環境に適合した質問紙を使用し、韓国の四年制大学に所属する専任以上の韓国人教師及び母語話者教師を対象に調査を行った結果を分析した。調査では、韓国人教師は、母語話者教師にどのような役割や能力を求めるか、母語話者教師は、大学にどのような役割や能力を求められていると認識しているか、についてそれぞれ回答してもらい、その結果を因子分析にかけた。その結果、韓国人教師から抽出された因子は、「授業実践能力」「融和的人格及び授業以外の役割」の「専門性」「韓国文化への理解及び周辺業務遂行能力」「韓国語能力」で、母語話者教師から抽出された因子は、「授業実践能力」「融和的人格」「韓国語能力及び熟練性」「韓国及び大学文化への理解能力」「授業以外の役割」であった。抽出された因子を比較すると、若干の相違が見られたものの、韓国人教師と母語話者教師との認識に大きな差はなく、韓国人教師の求める母語話者教師像を、母語話者教師は概ね認識していることが明らかとなった。a 日本との交流が活発化し、相互への関心が高まってきた今日、質の高い教育を実施できる母語話者日本語教師(以下母語話者教師を呼ぶ)が求められている。本研究の最終目標は、今後重点的に養成すべき教師の能力を発見し、質の高い教師の養成に必要な教育の方法を探ることである。そのために、韓国における質の高い母語話者教師とはどのような教師であるのかを明らかにする必要がある。その手段として、韓国の大学、特に四年制大学に注目し、韓国人教師、学習者さらに母語話者教師自身に調査を行い、包括的なデータによって韓国の4年制大学が求める母語話者教師の役割及び能力を分析していく。本稿では、韓国の教育環境に適合した質問紙を使用し、韓国の四年制大学に所属する専任以上の韓国人教師及び母語話者教師を対象に調査を行った結果を分析した。調査では、韓国人教師は、母語話者教師にどのような役割や能力を求めるか、母語話者教師は、大学にどのような役割や能力を求められていると認識しているか、についてそれぞれ回答してもらい、その結果を因子分析にかけた。その結果、韓国人教師から抽出された因子は、「授業実践能力」「融和的人格及び授業以外の役割」の「専門性」「韓国文化への理解及び周辺業務遂行能力」「韓国語能力」で、母語話者教師から抽出された因子は、「授業実践能力」「融和的人格」「韓国語能力及び熟練性」「韓国及び大学文化への理解能力」「授業以外の役割」であった。抽出された因子を比較すると、若干の相違が見られたものの、韓国人教師と母語話者教師との認識に大きな差はなく、韓国人教師の求める母語話者教師像を、母語話者教師は概ね認識していることが明らかとなった。
