摘要:

The efficacy of meditation-relaxation techniques has been widely researched in the laboratory, but their effectiveness for management of stress in organizational settings is still relatively unexplored. The present study compared relaxation and control conditions as part of a program of stress-reduction in industry. A total of 154 New York Telephone employees self-selected for stress learned one of three techniques — clinically standardized meditation (CSM), respiratory one method meditation (ROM) or progressive relaxation (PMR) — or served as waiting list controls. At 5.5 months, the treatment groups showed clinical improvement in self-reported symptoms of stress, but only the meditation groups (not the PMR group) showed significantly more symptom reduction than the controls. The meditation groups had a 78% compliance rate at 5.5 months with treatment effect seen whether subjects practiced their techniques frequently or occasionally. The safe and inexpensive semi-automated meditation training has considerable value for stress-management programs in organizational settings.

摘要:

The purpose of this investigation was to identify the longitudinal physiological and cardiological changes that occurred in a sample of male NASA executives who participated in an individualized physical conditioning program for 10 years. Only 19% discontinued program participation. Oxygen uptake increased significantly during the 10 years and the increase was attributed to those who exercised three or more days per week. Serum cholesterol exhibited an upward trend similar to the trend reported in the Framingham population, but systolic blood pressure decreased with age. About 30% of the executives exhibited cardiac arrhythmias during exercise. The incidence of PVCs and PACs increased with age. During the period studied, five executives developed sudden acute myocardial symptomatology which was not detected by the exercise stress test.

摘要:

This retrospective cohort study of 1,345 male employees with potential for exposure to acrylonitrile analyzes cancer incidence and mortality from 1956 to 1976. Expected numbers based on company and national rates have been computed based on person-years. The analyses consider calendar time, payroll classification, occupation, duration of exposure, severity of exposure, and latency. Overall, 25 cases of cancer occurred, with 20.5 expected based on company rates. Of these, eight were respiratory cancer cases, with 4.4 expected. Excesses were found primarily during the 1970–76 time period among wage roll employees who had worked during plant start-up. A trend toward increased risks was seen with increased duration and severity of exposure. Twenty cancer deaths were found, with 17.4 expected according to company rates. Since many cancer cases were recently diagnosed and are living, it may be premature to evaluate mortality statistics. These findings, coupled with results from tests in laboratory animals, raise the serious suspicion that acrylonitrile may be a human carcinogen.

摘要:

Some common diseases or accidents that kill or disable persons prematurely are preventable, delayable or sometimes curable if detected early. Prevention, delay or cure requires that individuals be informed of the risks and of the ways they can avoid them, and that those with habits that increase their risks change their behavior. The authors decided to attempt health education of employees and their families by using a carnival setting to make it attractive and memorable. Active participation and demonstrations were used to stimulate interest and involvement to promote learning. Attendance was satisfactory and post-carnival conversations and questionnaires suggest that this might be a useful method of promoting health and safety with employees and their families.

摘要:

Exposure to gram-negative bacteria and the presence of subjective symptoms among workers were investigated at an experimental compost plant. Four of the 11 workers reported nausea, headache, and diarrhea, an incidence greater than that reported by workers in a drinking water plant. The number of airborne gram-negative bacteria was high where household garbage was agitated by the technical equipment. The findings are similar to those in studies on workers in sewage treatment plants.
