PURPOSE: We investigated whether in utero exposure to magnesium sulfate is associated with lower incidence of neonatal mortality, morbidity, and neurodevelopmental abnormalities in very low birth weight infants. METHODS: We evaluated 172 infants with birth weight less than 1,500g. According to the maternal receipt of magnesium sulfate, we divided into two groups. We reviewed the medical records of mothers and their babies to evaluate clinical outcome. RESULTS: Of 172 infants, 58(GA 30.0+/-2.3weeks, BW 1,20+/-2221g) received magnesium sulfate prior to delivery for tocolysis or preeclampsia(study group). The remaining 114(GA 29.6+/-2.3weeks, BW 1,220 +/-198g) served as the control group. Neonatal mortality was not significantly different between the two groups(12.5% vs 26.0%). There was no significant difference between the two groups in neonatal complications' RDS(52.4% vs 67.6%), BPD(16.7% vs 29.6%), apnea(52.4% vs 67.6%), IVH(23.8% vs 31.0%), PVL(4.8% vs 11.3%), NEC(7.1% vs 7.0%), ROP(26.8% vs 41.2%), and neal infection(33.3% vs 54.9%). The duration of ventilator therapy(10.9+/-7.3 vs 14.2+/-10.6 days), oxygen administration(20.2+/-20.0 vs 24.3+/-19.9 days) and admission(51.5+/-16.9 vs 54.6+/-16.7 days) were not different. Among 64 patients in whom follow up evaluation was possible more than 1 year, the incidence of cerebral palsy or developmental delay was not different(12.0% vs 12.8%). CONCLUSION: Maternal receipt of magnesium sulfate does not seem to be associated with an appreciably reduced risk of neonatal mortality, morbidity, and neurodevelopmental abnormalities in very low birth weight infants.

The purpose of this study is to clarify success factors for desirable relationship between buyer and supplier in elementary school. Therefore, the survey questionnaire consisted of general background, past success, success difference, buyer-supplier relationship characteristics(trust, supporting status, communication behavior, conflict resolution techniques, supplier selection process). The subjects were 66 dieticians of elementary school in Inchon. The statistical analysis of data was completed using SPSS program. The results were summarized as follows : Average total cost/day per one person 1,156Won. The number of suppliers per one school were 6. 92.3% of the subjects were in favor of private contract, regarding contract methods of purchasing food materials. For the past success, degree of satisfaction about past their supplier showed 3.49 score. The present success difference was shown higher than the past success. There was significant correlation between the past success and the present success difference. Trust about suppliers showed 3.40score. Supplying companies hardly support for buying school. Among information quality(timely, accurate, adequate, complete, credible), timely and complete showed lower score than the other kind of elements. Among the buyer-supplier relationship characteristic elements, only trust correlated with satisfaction about suppliers significantly. Among the conflict resolution techniques, joint problem solving and persuasive attempts were often made use of by subjects. The supplier selection criteria were shown quality(7.47), supplier's capabilities(6.46), management plan(6.00), price(5.73), scale(5.48), assets(5.27), considers delivery(4.76) and technology(2.39). As results, trust was needed for the desirable relationship between buyers and suppliers. This study has some limitations. The data in this study were collected from only buyer. It is more desired to acquire data from suppliers also.

PURPOSE: The purpose of this study was to identify the conceptual structure of stressors experienced by nursing students during clinical practice. METHODS: Ten men and 10 women nursing college students were interviewed. The results were 208 ideas. By synthesizing and editing these ideas, the final statement was trimmed down to 39 questions. The next step was to have the participants classify these 39 final questions. They were asked to rate stress scores using a five-point scale. Through multidimensional scaling analysis and hierarchical cluster analysis yielded dimensions and clusters. RESULTS: Results of the study showed 2 dimensions which were classified as 'interpersonal relationship-practice system' and 'identity-practice environment'. It also yielded 8 clusters which were classified as 'role confusion', 'gender discrimination', 'attitudes of medical personnel and patients', 'comparison between fellow students', 'difference between theory and practice', 'disestablishing the role of practice guide', 'interference with training', and 'problems of the practice environment'. Further, stress factors and stress levels were differentiated depending on the gender of the student. CONCLUSION: The results of the study indicate that educators who are developing clinical practice programs and clinical practitioners should consider stressors during clinical practice and the educational implications to nursing students.
