Essential health education for deployment in underdeveloped countries.
Educating personnel regarding issues related to health and foreign travel has always been an important deployment concern. This article provides general health education guidelines pertinent to any deployment, but especially foreign deployment. The report is intended as a vehicle for initiating the health education process of nonmedical personnel prior to deployment.
Perception of enclosure effects of architectural surfaces in a large scale interior space.
It was hypothesized that the perceived enclosure effect of spaces would be dependent upon the explicitness of presented architectural surfaces according to the 1961-1970 model of Thiel. It was also hypothesized that the contribution of the surfaces would adhere to theoretical weights proposed by Thiel. It was further hypothesized that the perceived contribution of the surfaces to enclosure would be similar for men and women. 20 women and 10 men were presented 24 line drawings in one-point, eye-level perspective of the same furnished and occupied interior space. The line drawings differed only in the absence or presence of floor, wall, or ceiling surfaces. On an initial task the spaces represented by the drawings were ordered by the subjects from least enclosed (most open) to most enclosed (least open). In a second task the surfaces in a diagram were ranked according to their relative importance in determining the perception of the enclosing effect. The hypotheses were confirmed, and so provided support for the model that the explicitness of perceived surfaces contribute differentially to the perception of the openness of an environment.
Prevention and emergency field management of venomous snakebites during military exercises.
Summer exercises in the continental United States bring many military personnel in contact with our four types of indigenous venomous snakes. Personnel with a knowledge of these snakes, their habits, and habitat, and who exercise common sense are much less likely to fall victim to a venomous bite. When a bite does occur, timely and appropriate first aid can help to reduce the sequelae of an envenomation. Military medical personnel should be prepared to discuss snakebite prevention and field management with all personnel taking to the field this summer.
Quantitative muscle strength testing: a comparison of job strength requirements and actual worker strength among military technicians.
In this study the authors investigate the percentage of mismatch between job demands and worker physical capacity in Utah National Guard mechanics. This population had demonstrated a higher incidence of low back trouble than other job descriptions reviewed. The authors utilized onsite still and videotape photography and a computerized biomechanical strength prediction model to assess loads on the lumbosacral spine due to various job tasks. Job demands were then compared to the actual physical capacity of the individual workers based on static strength testing in job-related positions. A load cell on the testing apparatus entered the force generated into a computer which averaged the force of the last three seconds of a five-second lift. It was determined that as much as a 38% mismatch existed within this population for some job tasks which these workers were exposed to. Suggestions for preventing job-related low back cumulative trauma disorders are presented, including: engineering redesign, worker selection programs, work hardening, and others.
Malignant lesions of the eyelid.
Malignant tumors of the eyelid and ocular adnexa are often detected during routine examinations. Basal cell carcinoma is the most common of these tumors, followed by squamous cell carcinoma. Sebaceous gland carcinoma and malignant melanoma are seen less frequently. Malignant eyelid tumors may mimic a number of benign conditions. Early diagnosis requires a high index of suspicion, and biopsy of the lesion is often necessary.

Effects of an observer on conformity to handwashing norm.
Women were observed after elimination in a public restroom to determine the effects of the presence or absence of an observer upon the likelihood of handwashing. 18 of 20 subjects in the presence of another and 3 of 19 who were not observed washed. The difference in frequency of handwashing between the two groups was clearly significant.

Perception of spatial and social density.
The effects of family size on the perception of three abstract rooms that differed in social and spatial density were studied. The rooms were rated on the dimensions, evaluation, spirituality, activity, and aesthetic appeal. Of the 48 subjects half were from large families with six or more members, and half were from smaller families. Family size had no effect on the perception of the rooms. The room low in spatial density was perceived most favorably, and there was no difference in the perception of a room high in social density and one high in spatial density.

Effects of size of home town on environmental perception.
168 subjects used a 23-item semantic differential to rate forest, beach, small town, desert, and large city. The ratings served as dependent variables for 23 3 X 56 X 5 analyses of variance employing size of home town, subjects within size of home town, and type of environment. Size of home town was a significant effect on one of 23 scales; subjects from large and medium-sized cities rated environments more toward the good end of the good-bad scale than subjects from small towns. All main effects for type of environment were significant. The order in which environments were rated depended upon the particular rating scale. Significant interactions of home town by environment were examined in terms of the differential patterns of environmental ratings produced by subjects from various sized home towns.
