Objective: The purpose of this study was to evaluate clinical efficacy of fetal fibronectin as a marker to predictor of preterm labor. Materials & Methods: The study group consisted of sixty-eight healthy pregnant women, at gestational age between 24 and 36 weeks, who visited our department with vaginal discharge from April, 1995 to December, 1997. For comparison, we divided all of the pregnant women into two groups by the result of ROM-Check^®, positive groups(N=21) and negative groups(N=47). When preterm labor appeared, 50mg of ritodrine hydrochloride(Yutopar^®) mixed I liter of 5% dextrose solution was administered slowly intravenously. Results: 1) The gestational age at delivery and the interval time from admission to delivery in the positive groups were significantly shorter than those of the negative groups(p<0.05). 2) The positive groups had significantly lower birth weight and Apgar scores than the negative groups(p<0.05). 3) Among the negative groups, in case of tocolytics administration, the interval time from admission to delivery significantly delayed more than that time in case of no tocolytics administration(p<0.05). Conclusions: The detection of the fetal fibronectin in vaginal discharge had a useful method as a predictor of preterm labor. Tocolytics was more effective in the negative groups than in the positive groups.

This study is based on the examination of 157 employees at various types of construction sites in Kwangju and Chunnam. The purpose of this study is to examine their awareness of electrical installation at construction sites, as well as their consciousness of accidents and the occurrence types of electric-injury accidents. It emphasizes the importance of electric safety education, which is expected at construction sites, and reveals basic data for precautions against electric-injury accidents and efficient safety supervision. In respect of the degree of awareness of accidents, 93.6% of the employees in this survey showed a very high sense of the danger of such accidents. With respect to type of accident, 38.8% replied that accidental falls are the most dangerous, while 44.6% replied that they have experienced electric-injury. In regard to the types of the electric-injury accidents, 38.0% replied that leakage of electricity is the main source of such accidents. It is therefore necessary to strengthen educational programs and precautional plans for electric-injury accidents. It is furthermore required to intensify the periodical execution of safety education, increase the publishing of guidebooks for safety education, and provide for thorough establishment and management of electrical equipment.
