Back injuries in industry: a retrospective study. II. Injury factors.

To evaluate the impact of back injury on industry, the authors conducted an extensive retrospective analysis of injuries among hourly employees of The Boeing Company, the largest industrial manufacturer in western Washington. The Boeing Company provided injury information on 31,200 employees for a 15-month period from July 1, 1979 to September 30, 1980. From this information, we analyzed 4,645 injury claims filed as of February 28, 1981 by 3,958 different employees. There were 900 back injuries in this group. Claims were categorized according to total incurred cost (TIC), made up of the medical costs and indemnity costs. High-cost claims were defined as those with a TIC greater than $10,000, and low-cost claims were those with a TIC less than $10,000. Among 857 claimants with 900 back injuries, lifting or material handling was much more commonly considered the cause of injury than accidents such as slips or falls. Accidents, however, had a much greater tendency to result in an expensive claim. The authors could not make reliable conclusions regarding injuries and 32 job skill classifications. The rate of injury did not vary according to day of the week or month, but a significantly higher rate of high-cost back injuries was noted on the day shift than on the evening or night shifts.

The dysmature infant. Associated factors and outcome at 7 years of age.

Dysmaturity, diagnosed according to the Clifford criteria, was studied for the first time in a black population. The infants and matched control subjects were participants in the Collaborative Perinatal Study in Philadelphia from birth to 7 years of age. The incidence of dysmaturity was 25/1,000 live births; more boys than girls were born dysmature, reversing the normal male/female ratio found among black infants in the Collaborative Study as a whole. The condition was more common among post-term infants but did occur in earlier gestational weeks. The overall characteristics of the condition among this black population did not differ from those previously reported among white populations of various races. Surviving infants developed mentally and physically as well as control subjects. No prenatal or environmental characteristics were found that distinguished mothers of dysmature infants from those of nondysmature infants.

Extension neural network and its applications.

In this paper, a novel extension neural network (ENN) is proposed. This new neural network is a combination of extension theory and neural network. It uses an extension distance (ED) to measure the similarity between data and cluster center. The learning speed of the proposed ENN is shown to be faster than the traditional neural networks and other fuzzy classification methods. Moreover, the new scheme has been proved to have high accuracy and less memory consumption. Experimental results from two different examples verify the effectiveness and applicability of the proposed work.

Reflex bronchospasm-induced acute massive pulmonary collapse.

Acute massive pulmonary collapse following reflex bronchospasm is described in a patient undergoing general anesthesia. The authors suggest that a chest radiograph should be taken as routine procedure after the onset of airway constriction during anesthesia.
