    Objective: To test the validity of a sitting pad (SP) to measure desk based sitting time and transitions, against camera derived direct observation; and to compare the data with those from inclinometers in the ActivPAL3 (AP) and ActiGraph GT3X+ (AG). Methods: Australian employees (n=13; 9 women; mean age 30 ± 6.5 years) were provided with a SP, AG and AP in 2011. A camera recorded chair based transitions during a prescribed and a free living protocol. Mean sitting time and transitions were calculated for each device and intra-class correlations (ICCs) and mean differences between (a) the SP and the camera and (b) the AP, AG and camera, were compared. Results: During the prescribed protocol, the smallest mean differences compared with the camera were for the SP; sitting time 0.30 ± 0.21 minutes, transitions −0.46 ± 0.78. During free living, both the SP and AP (set to record events greater than 3 seconds) showed excellent levels of agreement with the camera for sitting time (0.999 and 0.990 respectively) and transitions (0.997 and 0.928 respectively). Agreement between the camera and the AG was poor for both sitting time and transitions (0.257 and 0.033 respectively). Conclusions: The SP is a highly accurate measure of desk based sitting time and transitions and provides novel measurement and intervention opportunities for research into occupational sitting.

    [Purpose] This study compared the upper extremity recovery of stroke patients with the amount of their upper extremity use in real life as measured by accelerometers. [Subjects] Forty inpatients who had had a stroke were recruited. [Methods] The subjects were divided into two groups by the Fugl-Meyer Assessment of Motor Function (FMA) score, a moderately recovered group and a well recovered group. The amount of upper extremity physical activity and its ratio in daily time periods were analyzed for the affected and unaffected sides. [Results] The well recovered group showed significantly higher affected arm use and use ratio than the moderately recovered group in all time periods. [Conclusion] The upper extremity recovery level of the affected side is similar to the physical activity level according to the amount of upper extremity physical activity in actual life measured with an accelerometer. Overuse of the normal side regardless of the recovery level of upper extremity proves the International Classification of Functioning (ICF) concept of differentiating between capacity and performance, and rehabilitation treatments should focus on improving performance.

    A cross-sectional study concerning working conditions and the fatigue complaints of assembly line workers employed in two different electronic factories (A and B) in Vietnam was conducted from August to September 1994.
    While general working conditions, such as noise, dust, heat and lighting, were worse in Factory B, the prevalence rate of the subjective fatigue after working time was significantly higher among workers in Factory A. Fatigue symptoms in category I (Drowsiness and dullness) were particularly apparent among workers in Factory A. More interestingly, one-third of workers in Factory A complained of stiff shoulders and low back pain. Our field observation results suggest that the ergonomic inappropriateness of the assembly line in Factory A, may be causing a high rate of subjective fatigue among workers.

    We document serial changes in the electrocardiogram (ECG) and myocardial markers in a case of severe heat stroke treated with cooling procedures. A 23-year-old comatose male with heat stroke was presented in the emergency room. The condition of the patient was complicated by hepatic failure, rhabdomyolysis, acute renal failure, and cardiac abnormalities. ECG revealed diffuse ST-T elevation; serum levels of myocardial markers were remarkably high and diffuse hypokinesis was observed on the echocardiogram. Cooling procedures, including applying cold vapor to the patient's skin, a gastric lavage with cold water, and an intravenous cold fluid infusion were not successful. Since multiple organ damage (heart, liver, central nervous system, and kidney) was evident, we utilized continuous hemodialysis and hemofiltration, using cold dialysate for efficient cooling. The patient recovered from the multiple organ damage and was removed from the intensive care unit 14 days after the onset. The cardiac abnormalities had normalized within several days without any damage to the myocardium. Q waves were not detected in any lead in the ECG. When interpreting ST-T elevation in the ECG of a heat stroke patient, caution should be used so as to not misdiagnose it as an acute myocardial infarction.

    The authors propose a method to make a movement plan for relocation of the railway cars in preparation for the final assembly. It obtains solution through three steps. The first step is to extract the order constraints between the movements of the railway cars based on their locations before and after relocation. The second step is to introduce the movement which puts a railway car into another location temporarily, in order to avoid a deadlock in the movements. And the final step is to obtain the movement order for carrying out the relocation in the shortest time in accordance with the calculated order constraints by using the genetic algorithm (GA). The order constraints are resolved in advance and therefore the movement order can easily be decided by GA. As the result, the developed system takes time shorter than an expert for planning the relocation.

    The workplace is an important field for smoking control, but there are relatively few reports on the current situation of workplace smoking control with the exception of reports from NorthAmerican countries. The aim of this study was to evaluate the effectiveness of workplace smoking control programs on the smoking prevalence among Japanese workers. A self-administered questionnaire regarding workplace smoking control programs was sent to 531 workplaces and a total of 315 workplaces returned the questionnaire. The number of employees in the study sample was 57, 051 males and 19, 818 females. The restriction of smoking area and/or time was found to be associated with a 13.1% and 44.5% decrease in smoking prevalence for males and females, respectively. The data were also analyzed, restricting to the workers in manufacturing industry which constituted the largest part of workers, in order to control a possible confounding arising from different characteristics among different industries. Restriction of smoking area and/or smoking time gave the largest effects of 15.4% and 36.2% lower prevalence in males and females, respectively. The differences observed in all female workers combined for individual consultation for smokers were also identified. In conclusion, it is suggested that workplace smoking control programs are effective at lowering the prevalence of workers who smoke.

    Objective: This study was conducted to explore the scope of practice for occupational audiologists in the mining industry and the audiologists' involvement in hearing conservation programmes in South African mines. Additionally, this study investigated the mining industry's role in the audiologists' involvement, and assessed the audiologists' levels of preparedness for working in occupational audiology. Methods: In-depth, qualitative telephone and face-to face interviews were conducted with seven occupational audiologists involved in the management of occupational, noise-induced hearing loss (ONIHL) in the South African mining sector. Snowball sampling was utilized to recruit possible participants for this study. Data were analysed using inductive thematic analysis. Results: The following themes were identified: scope-context misalignment, juniorization of the experts, audiologists are important... but for what?, and limited training in occupational audiology. Conclusions: Our evidence highlights important gaps in HCPs in South Africa. The fact that the audiologists responsible for the management of ONIHL are only minimally and peripherally involved may play a significant role in the lack of progress reported in the management of ONIHL in the South African mining sector.

    [Purpose] This study was conducted to compare the correlation between social interaction and activities of daily living (ADL) between community-dwelling and long-term care facility stroke patients. [Subjects and Methods] The Subjects were 65 chronic stroke patients (32 facility-residing, 33 community-dwelling). The Evaluation Social Interaction (ESI) tool was used to evaluate social interaction and the Assessment of Motor and Process Skills (AMPS) measure was used to evaluate ADL. [Results] Both social interaction and ADL were higher in community-dwelling than facility-residing stroke patients. There was a correlation between ESI and ADL for both motor and process skills among facility-residing patients, while only ADL process skills and ESI correlated among community-dwelling patients. In a partial correlation analysis using ADL motor and process skills as control variables, only process skills correlated with ESI. [Conclusion] For rehabilitation of stroke patients, an extended treatment process that combines ADL and social activities is likely to be required. Furthermore, treatment programs and institutional systems that can improve social interaction and promote health maintenance for community-dwelling and facility-residing chronic stroke patients are needed throughout the rehabilitation process.

    On designing the manual operation processes, it is important for process engineers to estimate the operation time and assume the worker's motion, in order to modify and optimize the process and workplace. 3-D Mannequin has useful functions for the engineers to make such estimation efficiently. However, the conventional 3-D Mannequin requires a lot of time to modify the process and the workplace data. To reduce the time, we have developed the support system, which enables users to modify the process and the workplace based on the already modeled data. By checking the difference of the type of motion and the position of object between the already modeled data and the modified data, the users only have to re-model the minimum required motion.

    Background: In Japan, although many new pharmacy graduates are keen to find work, the number of new job openings for hospital pharmacists is limited. In this survey, we explored the attitudes toward work among hospital pharmacists working in large group hospitals in order to help pharmacy students make informed career decisions.
    Methods: A cross-sectional, self-administered survey of 614 hospital pharmacists working in 66 institutions of the Tokushukai Hospital Group across Japan was conducted.
    Results: The proportion of usable data from surveyed pharmacists was 71.7%. Approximately 80% of the respondents desired to commit to careers in the healthcare field and were keen to gain opportunities for personal development. Personal development was the key item among reasons given for decisions about workplace and turnover. About 95% of the pharmacists surveyed were satisfied with their jobs. Compared to the job satisfaction level of other workers, that of pharmacists was considerably higher, although only 5.5% of pharmacists saw themselves staying in their current job until retirement. Job satisfaction data demonstrated significant differences among cohorts of age and years employed, although some specific items associated with job satisfaction could not be identified. Future work plans were influenced by age and job satisfaction.
    Conclusion: This study suggests that pharmacists working in group hospitals nurture positive expectations for their careers. Management needs to make greater efforts to understand the professional characteristics of hospital pharmacists in order to better utilize their professional abilities and skills for patient care and for the benefit of other healthcare professionals.

         This research aims to make clear the determinants of job shift patterns in Japan. Previous studies have highlighted the importance of both individual level of resource and reward, and labor market structures which affect job mobility patterns. However, previous research on job mobility in Japan did not incorporate individual level of attributes such as resource and reward into systematic theoretical points of view while the impact of labor market structure on job mobility drew distinctive attention in Japan. In addition, many previous studies did not take into account the context of job shift because of a lack of available source of information in survey data. The present research pays attention to the divergence between voluntary and involuntary job mobility. The result shows that firm-specific skills and occupational reward made it less likely for employees to quit a job. It corresponds to the model of reward and resource. However, there is no evidence that general human capital which is transferable across firm would increase the likelihood of quitting a job as is seen in the U.S labor market. In addition, the way in which labor market structure influences job shift patterns is almost identical to the model of segmented labor market. In contrast, the way in which macroeconomic conditions for labor market affects rates of job shift in Japan is deviant from the hypothesis for the U.S labor market. This paper highlights the differences between voluntary and involuntary job mobility in Japan. Compared to the previous studies in the U.S, the job mobility patterns in Japan appear to be roughly similar to the ones for the United States whereas it seems that the institutional arrangements specific to Japanese labor market could make the job mobility patterns substantially different from those for the other industrialized countries. Cross-national comparison of intragenerational mobility which has lacked empirical studies would be further needed so that we can make clear the underpinnings of job mobility structure and institutional arrangements of labor market which diverge job mobility across country.

    This study clarifies how workers stay in a place and move differently in territorial and non-territorial workplaces by using the UWB (Ultra Wide Band-impulse radio) sensor network. The results are as follows. All the investigated workers spent approximately 80% of their time for staying in the working territory in each workplace. Workers in the non-territorial workplace stayed in the "own-seat nearby zone" 8.4% more than those in the territorial workplace; they stayed 11.6% less in the "meeting corner zone", but 1.4% more in the "workstation zone". The working territory space in the non-territorial workplace was used more efficiently than in the territorial workplace, as indicated by its 8.5% higher proprietary occupancy rate and 2.8% higher flexible occupancy rate at workstations, as well as its 6.9% higher occupancy rate in meeting corners. The different work characteristics in terms of worker's post or specialty were also revealed: architects spent approximately 4.5% more time in the "own-seat nearby zone" than engineers, while engineers visited the architects' specialty areas more often; compared with regular staff, the rate at which project leaders stayed out of their workplace was the highest, at over 17%; while the temporary staff stay in the "own-seat nearby zone" the longest.

    Objectives: This study aimed to identify the practical abilities required by nonspecialist occupational physicians and specify the priorities for training programs. Methods: A practical abilities list was developed through a focus group meeting of specialists. We created a survey questionnaire and asked three groups, namely, occupational physicians, occupational health nurses, and health officers, to rate the importance of each practical ability. Results: The mean scores for all 45 items were greater than 4, i.e., in the middle of the 7-point Likert scale, for all the three groups. The occupational physicians' responses had a correlation with the other groups' responses. However, there were differences with regard to some practical abilities between the three groups. Five practical abilities from the top quartile were marked "A" by all the three groups: "Submit opinions on fitness for duty and work accommodation on the basis of data from health examination," "Respect employee privacy," "Submit opinion on fitness for duty and work accommodation on the basis of data from face-to-face interviews with employees," "Submit opinions on fitness for duty and work accommodation on the basis of data from health surveillance," and "Implement face-to-face interviews for employees who have worked overtime and evaluate the subjects' conditions including mental and physical health status, degree of accumulated fatigue, and depression." Conclusions: This study resulted in a rank-ordered list of 45 practical abilities that are required by nonspecialist occupational physicians. This result may be useful to review and redesign the existing training program for nonspecialist occupational physicians.

    [Purpose] This study aimed to investigate Japanese physical therapists’ attitudes of evidence-based practice and clinical practice guidelines. [Subjects and Methods] In 2014, a cross-sectional postal mail survey using a self-administered questionnaire was conducted. Of 2,982 physical therapists belonging to the Chiba Prefecture Physical Therapist Association, 1,000 were randomly selected. The questionnaire comprised 42 items pertaining to the attitudes of and behavior toward evidence-based practice and clinical practice guidelines. It was investigated to reveal the relationship between clinical practice guidelines/evidence-based practice and therapist characteristics. [Results] The response rate was 39.6%, and 384 questionnaires were available. The main results were as follows: 83.3% participants agreed to the importance of evidence-based practice, 77.1% agree to that evidence-based practice supports clinical decision of physical therapists, and about 11% agreed to have been educated about evidence-based practice. Then, 29.2% used, 54.9% agreed to the importance of, and 13.3% agreed to the utility of clinical practice guidelines. An important factor related mostly to a positive attitude, knowledge and behavior of evidence-based practice and clinical practice guidelines was participating in research activities. [Conclusion] Many of physical therapists do not use and understand the importance of clinical practice guidelines. Participating in research activities may partially contribute to improving these conditions.

    Background & Aims : The aim of the present study was to verify the impact of progressive muscle relaxation (PMR) in combination with breathing technique (breathing PMR) on self-control for stress management in patients undergoing treatment for type 2 diabetes mellitus. Methods : Twenty-four patients participated and were followed during a 2-month pre-intervention (baseline) period and a 6-month intervention period. Changes in salivary amylase concentration, blood pressure, heart rate, HbA1c level, and objective indices including relaxation scales, coping behavior scales, and mental health patterns extracted from semi-structured interviews were assessed before and after the interventions. Results : There were significant differences in the physical indices (salivary amylase concentration, blood pressure, heart rate) and relaxation scales between the pre-intervention and post-intervention periods (p<0.05-0.01). The HbA1c levels during intervention were stable in a better range compared with those of previous year (p<0.05-0.01). Subjective indices including coping behavior scales, mental health patterns, and other complaints tended to improve during concomitant breathing PMR. Conclusions : Continuous breathing PMR during treatment for type 2 diabetes mellitus may improve self-control and stress management.

    We have been developing the wearable muscle suit for direct and physical motion supports. The use of the McKibben artificial muscle has opened the way to the introduction of "muscle suits" - compact, lightweight, reliable, wearable "assist-bots" enabling manual worker to lift and carry weights. Since back pain is the most serious problem for manual worker, improvement of the back support muscle suit, operational system for practical use and interface suitable for the site under the feasibility study is shown in this paper. Also we investigate the ease of twisting of the body in the state where the muscle suit was worn and the effects of the muscle suit for lifting tasks.
