Numerous studies have documented an association between the state in which a physician practices and prior education in that state. To determine whether this relationship exists for recent family practice residency graduates, 95 randomly selected programs in which residents completed training in 1979 were surveyed to obtain information regarding practice location and medical school location for their graduates. Seventy-nine percent of physicians completing residency and medical school in the same state also practiced in that state. Of those completing residency in a state other than that of their medical school, 43 percent stayed in the state of their residency to practice, and 22 percent returned to the state of their medical school. An analysis of the impact that a policy restricting house staff positions to in-state students would have on physician supply for the state reveals that only about 10 percent more physicians would be expected to start practice in a state if such a policy were implemented.

The biochemical and physicochemical characteristics of nonrespiratory pulmonary functions were determined in 255 children of school age according to the condensate of exhaled air. As compared to the younger children, those belonging to the senior age groups manifested an increase of specific respiratory moisture loss. As compared to winter, specific respiratory moisture loss in summer was found to be decreased; the condensate of exhaled air was discovered to have a higher content of total protein, elevated concentration of surface active substances in the lung surfactant, and to show a certain tendency towards reduction of the intensity of the processes of free radical oxidation. No sex-associated differences were established between the characteristics under study.
The establishment of normal standards of dynamic pulmonary function measurements in the form of prediction equations will serve as a remedial measure of different aspects of obstructive pulmonary diseases, especially in children. With a view to achieving the target, dynamic pulmonary function measurements were undertaken on 328 healthy school-going children of West Bengal having age ranging between 9 and 18 years. All the spirometric measurements except PEFR were taken with the help of a 9 l closed-circuit type expirograph following the methods and techniques of American Thoracic Society. PEFR was measured by Wright Peak Flow Meter. Prediction equations were derived on the basis of age and height for all the pulmonary function measurements except FEV1% and FET. The prediction equations for FVC, FEV1, MVVF, and PEFR were reliable, but relative variability of predicted FEF25-75% and FEF75-85% was very large. A comparative study of FVC, FEV1, and PEFR values of our subjects, standardized for age and height, was much closer to the boys of Delhi in FVC but higher than South Indian boys in FEV1, North and South Indian boys in PEFR. In an attempt to compare FVC and FEV1 values of our subjects with foreign populations, it is revealed that boys of our study were much lower than American (White), European, and Jordanian boys but comparable with those of Chinese and Libyan boys.
School counseling and guidance services are specifically intended to develop and maintain positive mental health among students. Although some school counselors have been highly effective, the majority have been only moderately effective because of the difficulties they have encountered in this mission. Personal, academic, and vocational counseling and information processing from either remedial or preventative perspectives are currently the most common functions within school counseling services. The factors limiting the effectiveness of these and other school counseling functions include discrepancies between school counseling training and practice, school counselor professional isolationism, lack of understanding of school counseling roles and functions, and the poor professional attitudes of some school counselors. As the school counseling profession develops, these inhibiting factors should be overcome as a result of changes in school counselor roles and activities and associated changes in school counseling and guidance services.
The 1977 Montana legislature funded an extensive Montana Air Pollution Study (MAPS). One hundred and twenty children in the fourth and fifth grades in Missoula, Montana had their pulmonary functions tested on 6 days during the 1979-80 school year. On May 18, 1980, Mount St. Helens erupted, resulting in very high total suspended particulates (TSP) levels due to ash (peak day = 11,054 micrograms/m3 24-hour average) through May 22. When these children returned to school on May 23, they had their pulmonary functions tested a seventh time. There was no substantial decrease in pulmonary function after the ash exposure. By comparison, the childrens' pulmonary tests did show a significant decrease after 3 days of high urban air pollution (440 micrograms/m3 3-day average). Businesses and schools were closed for 4 days after the eruption and people were advised to remain indoors; hence, lack of measured pulmonary function test effects from the ash may be due to the protective precautions taken by the children.
Body functioning state of schoolchildren was investigated under different lighting conditions of the computer keyboard and video display terminals (VDT). The findings of lighting engineering and physiologic studies showed that optimal conditions for the children working on computers should be ensured by two interdependent indicators, i. e., the level of lighting at the workplace and on VDT. The most favourable indicators of children's visual functions were established at the level of lighting of 400 lx at the workplace and 100 lx on VDT under general luminescent lighting.
The relationship between static occlusion and functional occlusion was evaluated in 101 dental and dental hygiene students. The sample was selected from a population of 467 students who were enrolled at one dental school during the 1987-1988 academic year based upon the following criteria: age range 18 to 32 years; caucasian race; no prior orthodontic treatment; at least 28 natural teeth present; no occlusal adjustments; and no large restorations, crowns or bridges. Fifty-two (52) of the subjects possessed "normal" static occlusion, 26 had a Class I malocclusion, 16 were found to have a Class II malocclusion, and 7 had a Class III malocclusion. The majority (i.e., 75%) of the 101 subjects possessed non-working (balancing) functional contacts. Seventy-five (75) of the subjects possessed balanced occlusion, nine had canine-protected occlusion, nine possessed group function occlusion, and eight had mixed canine-protected/group functional occlusion. This study found no statistically significant relationship between static occlusion and functional occlusion, however, there was a trend for balanced occlusion to be more often associated with "normal" (ideal) static occlusion.
Seventy-six families of children with school phobia were evaluated with the Family Assessment Measure. Mothers and fathers, as separate groups, rated clinically significant dysfunction in the parent-child relationship in the areas of role performance and values and norms. There were no significant differences between intact and single-parent families on ratings of family dysfunction. There was significantly less family dysfunction as rated by mothers and by children if the child had a diagnosis of pure anxiety disorder compared to families of school phobic children in other diagnostic categories.

This study seeks to reconcile the widely varying estimates of prevalence of hyperactivity in children. Parents, teachers, and physicians were asked to identify hyperactive children in a sample of some 5000 elementary school children. Approximately five percent were considered hyperactive by at least one defining system; only one percent were considered hyperactive by all three definers. Prevalence rates were relatively constant from kindergarten through fifth grade.
