Background
: An Epidemiological study was undertaken to evaluate the prevalence of E. vermicularis infestation among children in kindergartens.

Methods : A total of 247 cellotape anal swab specimens from kindergarten children in Inchon were examined for E. vermicularis eggs. Each specimen was collected in the morning.

Results : Out of 247 specimens from two kindergartens in Inchon, E. vermicularis eggs were detected in 168 specimens, the egg detection rate being 68.0%. The egg detection rates in boys and girls were 63.9% out of 133 children and 72.8% out of 114 children, respectively. The egg detection rate in girls was higher than that of boys. The egg detection rates by age group was 65.6%(age 3), 57.4%(age 4), 72.0%(age 5) and 75.4%(age 6), respectively.

Conclusion : Enterobiasis is a cosmopolitan infection. Surveys for children of kindergartens indicate that E.vermicularisis probably the most widely distributed human helminth, its incidence varing from 59.2% to 73.8% in groups studied since pinworm infection is frequently a familial problem that infestation of the household frequently results in reinfection. Careful washing of hands and cleansing of fingernails before meals and after use of the toilet are the most practical measures, all member of family should be treated simultaneously when practicable.

Background
: Many examinees have mental stress due to difficulty to pass examinations. So we evaluated their health condition, medical illness, and wanted workup tests.

Methods : From May-1, 1995 to June-5 1995, we collected data from examinees at Shin Rim Dong, Kwan Ak Gu, Seoul, Korea. After giving them questionnaires, we reviewed and analyzed the results of questionnaires.

Results : The total number of examinees was 785, and the sex ratio was male : female=9.2 : 1. In the age distribution, and 3rd and 4th decades were 64.6% and 31.4% respectively. In the examination types, Bar Examinees were 50.8%, Governmental Officer Examinees were 31.0%, Governmental Fo-reign Officer Examinees were 4.2%, Certified Public Accountant Examinees were 8.3%. Real estate evaluator examinees were 5.7%. In the education levels, college graduates were 80.9%. For most of examinees(88.9%) the duration of preparing exam was less than 5 years. Diet habits were regular in most cases as 2~3 meals per day(90.8%), and nonsmokers were 34.9%, nondrinkers were 34.8%. The types of taking medicine were herb medicine(33%), vitamins(21.6%), digestive pills(19.5%). When they need medicine, they will get medicine from drug store(57.6%), medical doctor's office(15.5%), and Oriental doctor's office(9.9%). Most examinees slept for 5 to 8 hours per day(78.1%). And they hae experienced tension headache, which was related to stressful studies, and other medical problems related to gastointestinal problems(18.1%). Most of examinees were concerned about their health status, and that was why they requested some tests for health screening, which were LFT and hepatitis screening test(22%), and CBC test(18.3%), chest X-ray(17.2%).

Conclusion : Most of examinees were very much concerned about their health status due to long period of stressful studies. I found some of examinees had chronic medical problems. This chronic problems should be treated and regularly checked by medical doctors. These follow up health screening programs and routine physical examinations will give them better way for preparing examinations and their own health.
