본 연구는 유기용제 만성 폭로 근로자들에게서 급성 폭로후 폭로 중지 시간에 따른 신경행동검사의 변화 양상을 보기 위하여 시행되었다. 대상군은 1개 피혁운동화 제조업체에서 5년이상 근무한 여성 근로자 34명이었으며 NCTB증 4가지 항목-숫자 암기, Santa Ana Dexterity, Benton Visual Retention, 숫자 부호 짝짓기-을 1인당 3회 반복 시행하였다. 검사 시점은 각각 월요일 작업 시작 전, 평일 작업 시작 전, 평일 작업 중이었다. 시행 시점에 따라 유의한 수행 능력의 차이를 보인 항목은 숫자 암기 정순, Benton Visual Retention, Santa Ana Dexterity 우수와 열수, 그리고 숫자 부호 짝짓기였으며 특히 평일 작업 중의 수행 능이 월요일 작업시작 전, 평일 작업 시작 전에 비하여 통계적으로 유의하게 감소하였다. 또한 Santa Ana Dexterity 우수, 숫자 부호 짝짓기에서는 평일 작업 시작 전의 수행능력도 월요일 작업 시작 전에 비하여 유의하게 감소하였다. 전반적으로 고 폭로군, 50세 이상, 6년 미만의 교육수준에서 평일 작업 중의 수행능 감소가 뚜렷하게 나타났다. 이상에서 만성 유기용제 폭로의 중추 신경계 장애를 보기 위한 신경행동검사는 휴일 후 작업 시작 전에 시행하는 것이 바람직하며 단기 기억력과 관련된 검사 항목은 평일 작업 시작전에 시행하는 것도 고려해 볼 수 있을 것으로 보인다. This study was performed to see whether neurobehavioral tests was affected by the exposure-free time in the workers chronically exposed to organic solvents. Thirty-four female workers were participated and four items among neurobehavioral core test battery of World Health Organization, including digit span, Santa Ana Dexterity, digit symbol and Benton Visual Retention, were administered to the workers. Test was conducted three times-preshift on Monday, preshift on Weekday and during shift on Weekday-per person and the interval of tests was 2 weeks. Digit span forward, Santa Ana Dexterity, digit symbol, and Benton Visual Retention showed significant decrements by performing time, especially during shift on Week-day versus preshift on Monday and preshift on Weekday. In addition, the score at preshift on Weekday was significantly lower than preshift on Monday, in preferred Santa Ana Dexterity and digit symbol. Generally, those who were exposed to high concentration, over 50 years and under 6 years of education showed marked decrease of score at during shift. So, it would be desirable that neurobehavioral test is conducted at preshift on Monday and items related to short term memory could be considerable to be done at preshift on Weekday.

The purpose of this study is to estimate the minimum optimal scale(MOS) of the self-employed health insurance associations. Considering the high proportion of operating expenses, the author have selected 254 regional health insurance associations eon the 1990 Finance Report of the self-employed health insurance programs. Both a quadratic function and a hyperbolic function were chosen for the analysis. The dependent variables are the average maintenance cost per insured person and per household, and the independent variables are the number of insured members and of household The minimum optimal scale was obtained from the differentiation of the quadratic function. Major findings are summarized as follows: 1. The M.O.S. was calculated as 166,174 members (27,442 households) for the rural self-employed health insurance associations and 258,462 members (75,446 households) for the urban. Providing that both the rural and urban health insurance associations would be integrated, the M.O.S. be found to become 231,687 members (68,101 households) 2. Compared with the optimal minimum scale, the magnitude of the current health insurance association found to be much smaller, less than half of the optimal scale. 3. In order to reduce the operating cost, it is necessary to enlarge the operational scale of self-employed health insurance associations.
