This book review is fraught with either medical, logical, or ethical problems in all the nine points as follows: (1) the inadequate way in which exposure and health hazards are considered from the toxicological perspective, (2) problems in interpreting epidemiological information, (3) the failure to consider recent achievements in methylmercury toxicosis studies, (4) presenting the reviewers' own theories without regard to the content of my book while calling it a \"book review,\" (5) presenting and criticizing what Takaoka does not claim as if he does, and (6) making claims that are inconsistent with the three reviewers' own views.

We all have a goal that we aspire for in our life-our \"reason to live\". Health is a pillar necessary for achieving our goal in life and I believe that altruism is the basic principle of this pillar.

Next, I introduce the keywords necessary for understanding health and then present the points necessary for determining good health and for the role of each individual in issues concerning health. In conclusion, I would like to define health as a state of physical, mental and social well-being necessary for people to achieve self-achievement and happiness while living in society. Health is an attitude, and the very process of striving to achieve good health is itself \"good health\". In addition, altruism is fundamental to good health.

In this study, we aimed to clarify the factors related to work engagement in occupational health nurses from both aspects of work environmental and individual factors.</p><p><strong>Methods: </strong>An anonymous self-administered questionnaire was mailed to 2,172 occupational health nurses who belonged to the Japan Society for Occupational Health and were in charge of practical work. Among them, 720 responded and their responses were analyzed (valid response rate: 33.1%). The Japanese version of the Utrecht Work Engagement Scale (UWES-J) was used to measure their feelings on whether their job is worth doing. Question items at three levels, namely, work level, department level, and workplace level, were selected from the new brief job stress questionnaire as the work environmental factors. Three scales, namely, professional identity, self-management skills, and out-of-work resources, were used as the individual factors. Multiple linear regression analysis was performed to examine the factors related to work engagement.</p><p><strong>Results: </strong>The mean total score of UWES-J was 57.0 points, and the mean item score was 3.4 points. Among attributes, age, having children, and the position of chief or above were positively correlated to the total score, but the number of occupational health nurses in the workplace was negatively correlated to the total score. Among work environmental factors, work-self balance (positive), which is a subscale at the workplace level, and suitable jobs and opportunities to grow up, which are the subscales at the work level, were positively correlated to the total score. Among individual factors, self-esteem as a professional and self-improvement to be professional, which are the subscales of the professional identity, and problem resolution, which is a subscale of self-management skills, were positively correlated to the total score.</p><p><strong>Conclusions: </strong>In order for occupational health nurses to find their job worth doing, it is desirable that they will have options to choose diverse and flexible work styles, and that their employers will establish a work-life balance for the entire organization. It is preferable that the occupational health nurses can self-improve, and that their employers will provide opportunities for them to develop professionally. The employers should also establish a personnel evaluation system that allows for promotion. Results also suggest that the occupational health nurses need to improve their self-management skills, and that the employers should assign them to positions suitable to their abilities.</p>","PeriodicalId":35643,"journal":{"name":"Japanese Journal of Hygiene","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9312994","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the advancement of science and technology, which is the driving force behind the expansion of profits, has forced people to become obsessed with new technology and information, and as a result, we have also lost our mental comfort. In this paper, first, we explain the time required to secure the energy necessary for human survival throughout human history.

We, who were also engaged in this research at Kumamoto University, would like to address some substantial viewpoints. Drs.
