  • This study is to develop the model on the joint employment system of occupational health nurse practitioners for medium or small sized enterprises in Korea based on the comparison opinions between employers and occupational health nurses (OHN). The data were collected by questionnaires from Oct. to Nov. in 1997. The number of subjects was 210 OHNs and 176 employers, response rate was 47.1% for OHNs and 23.2% for employers. The SAS PC program was used for the descriptive statistics. The results were as follow: 1. More than three years career was preferred for qualification of OHN by employers and OHNs. OHNs preferred that all instruments and materials should be equipped in each industry, but employers preferred that they should be equipped by OHN. 2. For the limit number of industries and employees per one OHN, employers preferred average 2.25 industries and 307 employees, OHNs preferred average 3.0 industries and 448 employees. Both of them preferred two times visit per week for all day long. 3. OHNs wanted that the local office of Ministry of Labor could act as mediator, but employers preferred direct contact individually. For the average wage, employers preferred 887,000 won per month, but OHNs preferred 1,960,000 won per month. 4. OHNs preferred the Korean Association of Occupational Health Nurse as the recruit agency. Finally, employers and OHNs have the opinions that they can choose this system depending on the condition. There is in need of development of effective strategy for this new system such as manpower development, cost-benefit analysis, establishment of occupational health service standard, advertisement for employers, and government supported project.

  • The development of synovial membrane from knee joint was studied by electron microscope in human fetuses ranging from 20mm to 260mm crown rump length (40days to 30weeks of gestational age). At 40mm fetus, developing synovial tissue was observed in homogenous interzone as a vascular mesenchyme around the periphery. The primitive joint space was appeared after the intermediate layer of the interzone in direct contact with chondrogenic layer at 60mm fetus. Differentiation of the synovial membrane coincided with clarification of the joint cauity. When dilatation of the synovial cavity occurred, the two types of synovial cells were well endowed with rough endoplasmic reticulum. At 100mm fetus, type A cells with a markedly attenuated cytoplasm were found as well as those cells which contained pinocytotic vesicles and vacuoles. By 150-200mm fetuses a majority of the intimal cells were type B. These cells were characterized by abundant rough endoplasmic reticulum and well developed Golgi complex. In contrast, A-type cell had numerous filopodia, pinocytotic vesicles lysosomes, and large vacuoles containing amorphous material. At 260mm fetus, the intimal cells were well developed and plentiful. The most marked difference between the synovial membrane of full-term fetus and adult was the large amount of collagen in the latter. During fetal period, the B-cells were most numerous cell type in the intimal cells. The B-cells were clearly distinguishable from the A-cells by their content of extensive rough endoplasmic reticulum and well developed Golgi complex.
