We manufactured a wearable particle monitor (WPM), which is a simple and low-cost dust monitor. We aimed to evaluate the usefulness of the device by using it and location information of a Global Navigation Satellite System (GNSS) to measure dust generation in outdoor workplaces. We used nine WPMs and a particle counter KC-52 to measure in parallel the dust concentration diffusing standard particles in a dust exposure apparatus to evaluate the measurability of the WPM, and visualized dust generation in outdoor workplaces to evaluate its usability. We obtained location information using a GNSS in parallel with measuring with the WPM. The measured values of the WPM followed the measured values of the KC-52, with a strong correlation of the values between the KC-52 and each WPM. The discrepancy among devices tended to increase, however, because the measured values of the WPMs increased. For outdoor measurements, we could create a heat map of the relative values of dust generation by combining two data of the WPM and the GNSS. The methods of using the WPM could overview the conditions needed to produce dust emissions in dust-generating workplaces.
Although measuring the workplace protection factor (WPF) is important to verify the performance of particulate respirators in a real work environment, there are no reports of such measurements in Japan. The aim of this study was to measure the WPF of a replaceable particulate respirator (RPR) and a powered air-purifying respirator (PAPR). Eight participants were subjected to three conditions: wearing a RPR correctly (C-RPR), wearing a RPR as usual (but incorrectly) (U-RPR), and wearing a PAPR in the same way as U-RPR (PAPR). Subjects performed dust-generating tasks for 15 min, during which the WPF was measured. The WPF was calculated by dividing the concentration of particles outside the particulate respirator (Co) by that inside the particulate respirator (Ci). A fit testing instrument was used to measure the number of particles. Ci was measured by inserting the test guide into the face piece, and Co was measured by fixing the test guide near the breathing area of the subjects. The WPF geometric mean values (standard deviations) for C-RPR, U-RPR, and PAPR were 17.7 (2.59), 27.0 (3.86), and 117.3 (5.25), respectively. It is important to generate knowledge about the performance of particulate respirators to prevent occupational respiratory diseases.
To review studies on work ability (WA) and its relationship with the biopsychosocial factors of professional drivers. We performed a scoping review of articles published until 2021, extracting location, study design, sample characteristics, transport category, WA assessment methods, and health-related factors. Eighteen studies were found in different transport categories around the world. Most of the studies were cross-sectional (15/18, 83%), in a single branch of professional drivers, and the Work Ability Index (WAI) appears as the most common assessment instrument (7/18, 39%). The characteristics of work organization, lack of physical activity, comorbidities, and psychosocial and ergonomic factors are associated with musculoskeletal symptoms and stress in professional drivers. Comparisons of WA and related factors between studies and professional drivers are limited due to the multiplicity of assessment methods.
The aim of this study is to enrich nursing education by clarifying the relationship between personality traits, motivation, and career paths in professional nursing. This cross-sectional study surveyed 150 nurses from a polyclinic in Japan that performs internal medicine and surgery. The survey covered several aspects of personality, work motivation, and career development using the Ten-Item Personality Inventory, Work Motivation Scale, and Nurses’ Job Career Scale. The demographics of the participants were also recorded. Multiple regression analysis revealed that the personality traits extraversion and agreeableness had a direct and positive impact on nurses’ interest in team collaboration, but not on career development. Interest in career improvement was related to conscientiousness as a power toward purpose and openness as an aspect of curiosity. Conscientiousness and openness were indirectly related to the development and adjustment of interpersonal relationships and self-capability development through interest in career improvement. Interest in patient support positively impacted the implementation and pursuit of quality nursing. The findings highlight the need to account for individual differences in personality and motivation to support nurses’ success during their nursing education and in the workplace.
Occupational hearing loss is a common complication among construction workers, especially those working with heavy machinery and construction equipment. This research measured the noise that construction operators are exposed to, and proves that most of the construction equipment operators that we studied have a potential risk of hearing impairment. We examined 22 types of construction machinery that are commonly used in various stages of construction projects in Tehran (demolition, excavation, and execution). The noise that construction operators were exposed to was measured with a dosimeter during 8 working hours, and the Time-Weighted Average (TWA) was calculated for each operator according to OSHA standards. Finally, a suitable hearing protection device (HPD) was suggested. The results indicated that the operators of D8N (opened-cab) and CAT D8L SA (closed-cab) bulldozers were exposed to more noise than other operators in this study. Hand-saw, Caterpillar 943, and Komatsu 470 loader operators were also exposed to significant noise levels. Other operators, such as drivers of older Benz and Volvo trucks, the Backhoe HLB95, the Soosan mobile crane, and the Bobcat were also exposed to heavy noise that put them at risk of occupational hearing loss.
In this paper I explain a well-known grammatical contrast that has been studied in the framework of Generative Grammar: the contrast between arguments and adjuncts in the preposition stranding of Wh-Questions. I make use of some recent minimalist studies: the Labeling Algorithm (LA) and the external Pair-Merger analysis based on LA. I also show that the grammaticality of heavy DP shift (HDPS) constructions, which have the same syntactic properties as Wh-questions but do not show the contrast between arguments and adjuncts in preposition stranding, can be adequately explained by the above analysis and some additional assumptions in Phase Theory. Finally, I will show that null operator (NOp) analysis is useful for the grammaticality of parasitic gap (PG) constructions, which at first glance may seem to be an empirical problem for the framework of this paper.
Although 70% of people in Japan wish to die at home, only 13.6% do, and 72.9% die in hospitals. This study aimed to clarify, from the perspective of visiting nurses, the factors influencing patients and their families in deciding the place of death and their satisfaction with end-of-life care at the chosen place. We conducted a survey of 70 visiting nurses with over a year of home nursing experience. They responded to the key factors influencing the decisions of patients and their families regarding place of death, either hospital or home, and the satisfaction at each place of death on a 10-point scale. 67 nurses valued the following two items when the place of death was a hospital: “Less burden of care on the family” and “Specialized treatment to alleviate suffering.” The following four items were emphasized in the home: “I can live my own life as I want,” “I can have my family be there when I want them to be,” “I can receive extensive nursing care,” and “I can be seen by my family doctor.” The nurses also rated the satisfaction of patients and their families much higher when they die at home than in a hospital. Therefore, improving the treatment environment based on the features of the place of death, and enhancing community-based end-of-life care support, would allow patients and their families to spend their own time in the hospital and get specialized treatment at home, resulting in greater satisfaction with end-of-life care.
The purpose of this study is to clarify the practices of Certified Nurses in Dementia Nursing during the 2019 Coronavirus pandemic (COVID-19) from two perspectives: 1) protecting elderly people with dementia from contracting the virus and 2) providing basic care for dementia to ensure the maintenance of cognitive function and comfort and safety. A self-constructed questionnaire was used to survey 386 Certified Nurses in Dementia Nursing working at hospitals in 23 prefectures where more than 30% of the population is 65 years old and over about their nursing practices and the measures they were taking during the COVID-19 pandemic. It was clarified that the certified nurses devised ways to prevent infection without undue imposition on people with dementia, and that they facilitated interactions with people and created a comfortable environment while paying attention to the prevention of infection.
A 49-year-old man was diagnosed with autoimmune pulmonary alveolar proteinosis. Chest computed tomography (CT) showed typical CT findings of pulmonary alveolar proteinosis: thickening of septa with ground-glass opacities in both lung fields. The diagnosis of autoimmune pulmonary alveolar proteinosis (PAP) was based on findings of bronchoalveolar lavage (BAL) fluid with milky appearance and elevated serum titer of anti-granulocyte-macrophage colony-stimulating factor antibody. We decided to perform segmental BAL via bronchoscopy. The surgery was performed under a general anesthesia since the patient had severe hypoxemia and strong cough reflex. Following 3 repeated courses of therapy, his respiratory condition and the ground-glass opacity in both lung fields improved remarkably, with no recurrence in 3 years. There are only a few published case reports in the world of the usefulness of segmental BAL under general anesthesia for PAP. We consider that segmental BAL is a useful therapeutic method for PAP in cases with severe hypoxemia, such as the present patient.
The Department of Nursing, School of Health Sciences, University of Occupational and Environmental Health provides the specialized course “Clinical Practice in Adult Nursing (Chronic Care)” as a compulsory subject for third- and fourth-year students to acquire the basic skills required in nursing practice for adult patients with chronic diseases. Students are trained in hospital wards and in outpatient medical departments/admission support units for a total of 3 weeks to communicate directly with patients with chronic diseases, and to deepen their learning about the specialty of chronic nursing care. The COVID-19 pandemic forced the Department of Nursing to hold prompt discussions and determine an appropriate method to provide clinical training under this situation. It decided to cancel the conventional face-to-face training program, which was scheduled to start in May 2020, and to implement an online training program instead. Remote training was provided using the online conferencing system Zoom. The online training program was designed to realize simultaneous bidirectional training. To prepare for the training, simulated cases and simulated medical records were created. Faculty members played the roles of “simulated patients”, “clinical supervisors”, and “faculty members”, while adopting elaborate approaches to help students develop nursing practice in real time. As a result, students were able to participate in training with a real feeling, even in an online environment, as they communicated with simulated patients daily, similarly to the case of clinical training. They also realized the limitations of learning without using the five physial senses and providing patient support with appropriate timing, revealing challenges specific to online training.
Pesticides are essentially toxic to living things, and, as they are used openly, it is necessary to monitor them and to prevent their adverse effects. A self-administered questionnaire survey given to a group of the greenhouse farmers told us that some of them developed dermatitis from acaricide cyflumetofen, so we conducted an interview study on dermatitis caused by cyflumetofen. The participants were affiliated with a strawberry producing group, and were interviewed at their annual health checkups in the spring of 2016 and 2017. The questions covered the status of spraying, dermatitis from cyflumetofen, and visitations to clinics/hospitals. Of 108 farmers interviewed, 20 had subjective symptoms of dermatitis from cyflumetofen. Seven of them had visited clinics/hospitals. The most affected body part was the face, especially around the eyes, followed by the hands and forearms. The subjective symptoms varied from slight (rubor and itching) to serious (swelling with aching around the eyes). Three male farmers had visited clinics/hospitals for 3-4 weeks, and had stopped using cyflumetofen. We advised them to continue avoiding the use of cyflumetofen, considering the results of an animal test: a “pesticide abstract” stated that cyflumetofen had caused skin sensitization in guinea pigs. It is necessary, therefore, to mention this skin sensitization in the safety datasheet of cyflumetofen.
