BACKGROUND: The Utrecht Work Engagement Scale (UWES) is widely used as a psychometric assessment scale to measure work engagement by relative evaluation. Determining standard values for absolute evaluation would make it more useful. The merit of absolute evaluation is that it can offer an objective evaluation to personnel members regardless of their status in the organization. OBJECTIVE: This study examines the criteria for absolute evaluation of the Japanese version of UWES-9 and creates a database for the evaluation of work engagement. METHODS: To examine the evaluation criteria for the total points of UWES-9 for 417 automotive industry workers, responses were validated via a one-way analysis of variance and receiver-operating characteristic analysis, using the scales of "worthwhileness of work" and "level of job satisfaction" in the Brief Job Stress Questionnaire with similar work engagement concepts. RESULTS: In both scales, the ability to predict was at its highest when divided into the high work engagement group (wherein the total points of UWES-9 are 21 points and above). CONCLUSIONS: In the relative evaluation, 24 points from the average of the total points of UWES-9 is the standard. In the absolute evaluation, the lower standard around 21 points is probable.

Abstract Background Maharishi Amrit Kalash (MAK) 5, one of the Ayurvedic food supplements, belongs to a group of substances known as Rasayana. MAK5 and other Rasayanas are believed to enhance the body's resistance to infections and disease, and enhance longevity. In this study, we determined the effects of administration of MAK5, one of the Ayurvedic food supplements on immune functions in young and old mice. Methods Male C3H/He N mice were divided into five groups: two no treatment groups (old control: 22-month-old and young control: 2-month-old) and three MAK5 treated groups with differing dose of MAK5. MAK5 was given p.o. at 50 mg/kg, 100 mg/kg or 200 mg/kg per day (3 days/week) for 2 months. Results We found that glucose consumption of peritoneal macrophages from old mice treated with MAK5 at all doses and incubated for 48 and 72 h were significantly greater than that in the control group. Nitric oxide production of peritoneal macrophages stimulated by lipopolysaccharide (LPS) in old mice treated with MAK5 at all doses was significantly greater than that in the old control group, but not compared to the young control group. Stimulation index (S.I.) in old mice gavaged with MAK5 at all doses was significantly higher than that in the old control group. IL-2 production stimulated by Con A in old mice given MAK5 at all doses was significantly higher than that in the old control group. Production of IFN-γ stimulated by Con A in old mice given MAK5 at doses of 100 mg/kg and 200 mg/kg were significantly higher than that in the old control group. IL-4 production of splenic lymphocyte stimulated by Con A in old mice given MAK5 at dose levels of 100 and 200 mg/kg were significantly higher than that in the old control group. Conclusion The results suggest that MAK5 suppressed the age associated glucose consumption of peritoneal macrophages and cellular immune function reduction, and that it contributes to the prevention of the immunosenescence.

Background. We analyzed muscular activity for different computer mouse positions during the completion of a timed computer task and determined whether the different mouse positions could affect muscular activity, productivity and perceived fatigue.Methods. The subjects were nine healthy young men. Two mouse positions were studied: the distal position (DP), with the forearm rested on the desk; the proximal position (PP), with only the wrist rested on the desk. The subjects performed a 16-min task in each position. Surface electromyography data were recorded for the upper back and shoulder muscles. Work productivity and muscular activity were measured for each mouse position. A visual analog scale was used to assess subjective fatigue.Results. Muscular activity was higher in muscle (m.) deltoideus (posterior) for the DP, while it was significantly higher in m. inferior infraspinatus for the PP. The visual analog scale score was significantly higher and work productivity was lower in the PP.Conclusions. We found that using a mouse in the DP rather than the PP leads to less activity of the external rotators, less perceived fatigue and more productivity. This suggests that the DP is preferable to the PP for computer work involving a mouse. [ABSTRACT FROM PUBLISHER]

Objectives: The aim of this study was to assess the present status of working environments for pharmacists, including the concentrations of suspended particles and suspended drug ingredients in dispensaries. Methods: We conducted a survey on the work processes and working environment in 15 hospital dispensaries, and measured the concentrations of suspended particles and suspended drug ingredients using digital dust counter and high-performance liquid chromatography tandem mass spectrometry (LC-MS/MS), respectively. Of 25 types of powdered drugs that were frequently handled in the 15 dispensaries surveyed, 11 could be quantitatively determined. Results: The amounts of suspended particles were relatively high, but below the reference value, in three dispensaries without dust collectors. The sedative-hypnotic drug zopiclone was detected in the suspended particles at one dispensary that was not equipped with dust collectors, and the antipyretic and analgesic drug acetaminophen was detected in two dispensaries equipped with dust collectors. There was no correlation between the daily number of prescriptions containing powdered drugs and the concentration of suspended particles in dispensaries. Conclusion: On the basis of the suspended particle concentrations measured, we concluded that dust collectors were effective in these dispensaries. However, suspended drug ingredients were detected also in dispensaries with dust collectors. These results suggest that the drug dust control systems of individual dispensaries should be properly installed and managed. [ABSTRACT FROM AUTHOR]

The article presents a study on the economic benefits of a comprehensive mental health prevention programs in Japanese work environments. The researchers have conducted a cost-benefit analyses on return of investment on individual labor and employee welfare. It implies that mental health programs are effective cost-saving options for employers in terms of absenteeism, work attitudes, and labor turnover.

The article focuses on a study on the evaluation of the effects of indoor cooling and cold storage goods on the prevalence of subjective musculoskeletal symptoms in summer. It informs that the main subjects of the study were female workers sorting cold storage goods and engaged with sorting of dry goods and a questionnaire covering age, occupational career and present or past history of diseases was also used.

The article focuses on a study about effects of cold exposure on the musculoskeletal system of male electricians working during the summer and winter seasons. A self-administered questionnaire was used to collect several information of the workers and their supervisors. The results reported that effects of cold on the musculoskeletal symptoms like prevalence rates of stiffness, numbness, pain and Raynaud's phenomenon were higher in workers than in the supervisors.

The article discusses the health conditions of traffic control workers and construction workers in Japan as subjective symptoms and cold prevention measures are compared. The measured dry bulb temperature and wind velocity of the work environments were calculated by the Windchill Index. Winter season brings symptoms such as stiffness in the neck and shoulders, and cold sensation in the fingers.

The modifying effects of auraptene isolated from the peel of citrus fruit (Citrus natsudaidai Hayata) on macrophage and lymphocyte functions were investigated in mice. Female BALB/c mice were gavaged with auraptene at a dose of 100, 200 or 400 mg/kg once a day for 10 consecutive days. Glucose consumption of peritoneal macrophages was significantly higher than that in the control group (P < 0.05–0.001) in auraptene-treated mice at all doses at 24, 48 and 72 h incubation except for mice given 200 mg/kg auraptene at 24 h incubation. Activity of acid phosphatase in peritoneal macrophages was significantly increased in mice treated with auraptene at a dose level of 100 mg/kg (P < 0.001). Activity of β-glucuronidase in peritoneal macrophages in the auraptene-treated mice at all doses was significantly higher than that in the control group (P < 0.001), but there was no significant difference in lactate dehydrogenase activity of peritoneal macrophages at any dose. Interleukin (IL)-1β production of peritoneal macrophages in the auraptene-treated mice at all doses was significantly higher than that in the control group (P < 0.05–0.001). Tumor necrosis factor α production of peritoneal macrophages in mice gavaged with auraptene at a dose of 200 mg/kg was significantly higher than that in the control group (P < 0.05). Auraptene did not affect proliferation of spontaneous splenic lymphocytes in mice at any dose. Stimulation indices in mice given auraptene at a dose of 200 mg/kg were significantly higher than that in the control group (P < 0.05). When spleenic lymphocytes were cultured without concanavalin A (Con A), IL-2 and interferon (IFN) γ productions were not detectable in the supernatant. However, IL-2 and IFN production stimulated by Con A were significantly increased in mice gavaged with auraptene at dose levels of 100 and 200 mg/kg (P 0.05–0.001). Auraptene did not enhance spontaneous IL-4 production by splenocytes. There was no significant difference in IL-4 production of splenic lymphocytes stimulated by Con A in all groups. These findings might suggest that oral administration of citrus auraptene effectively enhanced macrophage and lymphocyte functions in mice. [ABSTRACT FROM PUBLISHER]
