ABSTRACT
The purpose of tliLs study was to cvaTuate the actual condnzonK and problems of health manager health record maintenance and general health examinations in small-scale industries which employ 511 to ISO workers. A survey was conducted in 3iS conipanies in which industries health management is dele-gated to a social organization, the Taegu-kyungpook branch of the korean Industrial Health Organization, and companies in which health is managed by Ideal physicians. There was accomplished from March to April 1989 by Questionnaires through the mail, The following are the summarized results. 1. Health Management. The companies with non-vicarious execution of health management by local physicians ranked significantly, lower in frequency of visits, contribution to workers' health, and workers' desire for frequency of visits than the companies with vicarious execution by KIHA. 2. Health Records. The percentage health records on file was higher in the companies with vicarious execution than the other group. But most of the cnotents of the records were not described in great detail. 3. General Health Examination. The necessity of health examinations was recognized by all survey participants, but the reliability of the examinations was one of the major problems. The reporting period for results was significantly longer in the companies with vicarious execution than the others. Improvements were preferentially demanded with respect to the reliability of techiques and examinatio skill, follow-up study for secondary examination, and selection of examination items.

This study was carried out to clarify the effect of dietary calcium, casein, and suet on the accumulation of cadmium in mice. It was performed for 30 days, from April 11 to May 10 1988. 90 mice were divided into 4 experimental groups and control group with 6 mice each dietary group, and measured survival rate, body weight, and weight ratio of organ to body. The contents of cadmium in liver, kidney, spleen, muscle and skin with hair, and faces were analyzed by atomic absorption spectrophotometer after sacrifice by anesthesia. After 30 days, the survival rate of control group was 100%, but 66.7% in group IV(basal+Cd+Ca) with single dose of 100 microgram cadmium and with free-intake of water containing 50ppm cadmium, and group V(basal diet+Cd+suet) with free-intake of water containing 50ppm cadmium. The rate of weight gain in the case of single dose of 100 microgram cadmium was highest in group IV as 42.3% and lowest in group V as 26.0%, whereas in the cases of free intake group IV was highest as 24.0% and group II(basal diet+Cd) was lowest as 11.6%. The body weight, in the case of single dose of 100 microgram cadmium showed no increase until 5th day after acute poisoning. But in the case of free intake group, it showed very increase through all the breeding period. The weight ratio of organ to body were lowest in the liver of group II in both occasions. The most of cadmium administered were excreted through feces within 2 days after single dose of 100 microgram cadmium. The contents of cadmium in each group were significantly higher than those of control group. In the liver, kidney, spleen and muscle, group II showed the highest level in both occasions of 100 microgram single dose and free intake of water containing 50ppm cadmium. In the skin with hair, group II of the occasion with single dose of 100 microgram and group V with free intake showed the highest level. And the contents of cadmium in tissue were markedly higher in the occasion of free intake of water containing 50ppm cadmium. From the above results I would conclude that the addition of casein and calcium are effective in the inhibition of intension absorption of cadmium esp. by calcium.
