This study was conducted to investigate the changes of physico-chemical properties of soil applied with compost made by food wastes and its effect on the growth and yield of Chinese cabbage. Chinese cabbage was grown in the soil treated with food waste compst(FWC) of 0, 0.625, 1.25, 2.5, 5 and 10㎏/3.3㎡. As the amount of FWC increased, number of leaves, leaf area and fresh weight increased where application of 5㎏ and 10㎏/3.3㎡ showed vigorous plant growth in the late growing period. The pH of soil by application of FWC was not raised, which was similar to the soil before treatment. Organic matter increased in soil by increasing the amount of FWC. However, concentration of Cu and Pb in the soil reduced. The concentration of available phosphate(P) was lower in the soil treated with FWC than in the soil before treatment, which means that a large amount of P may be uptaken by plant. This study suggested that FWC should be an alternative to chemical fertilizer for vegetable production.

This study was conducted to find out toxicity of compost made of food waste to cucumber seed germination and seedlings growth when it was mixed with Mixlite for bed substrate. Mixlite was solely used as bed soil, or mixed with food waste compost ranging 1% to 100% (w/w). Germination percentage and seedling growth of cucumber were examined in 4 weeks after seedling. When cucumber seeds were sowed in Mixlite mixed with food waste compost at 100, 50, 30, 20, 10 or 1%, germination percentages were 30, 36, 38, 46, 74 and 84% compared to with control(100%), respectively. It showed that germination percentage percentage was adversely affected by the amount of food waste composed mixed in the bed substract. Plant height and hypocotyls diameter, root length and root fresh weight, hypocotyls fresh weight and cotyledon fresh weight of cucumber seedling were similarly adversely affected by the amount of food waste compost. Optimum content of the food waste compost for cucumber nursery substrate was found to be 1% of Mixlite.

The purpose of this study was to investigate how preceptor experience has an effect upon preceptor nurses. This study was so designed that it could compare the difference between clinical performance and Job satisfaction of preceptor nurses and those of nonpreceptor nurses. Study subjects were sampled out from those nurses who worked with two university hospitals where preceptor programs were implemented. The number of subjects totaled to 134, including 69 preceptor nurses and 70 nonpreceptor nurses. The score of preceptor nurses' clinical performance and job satisfaction revealed a higher value than that of nonpreceptor nurses. A similar result was also shown in the subdomains. However these difference were not statistically significant. Among all of the preceptor nurses, the highest number of preceptor experience was just one time. Except for five times in preceptor experience, the more the number of times of preceptor experience, the higher score in clinical performance. It was manifested that the number of preceptor experience was not related to job satisfaction. The score of preceptor nurses' clinica1 performance and job satisfaction revealed a higher value than that of nonpreceptor nurses. A similar result was also shown in the subdomains. However these difference were not statistically significant. The reward that preceptor nurses wished most was a reduction of the work load assigned to them. Currently preceptor nurses are only receiving a small quantity of financial reward related with their preceptor role. Most of preceptor nurses (96.8%) were not satisfied with their existing reward. Almost half of the preceptor nurses(43.5%) did not want to play a role as preceptor again. The reason why the scores of clinical performance and job satisfaction were low might be attributed to the inadequate preceptor training program and reward system. Appropriate knowledge and clinical skill are expected to enhance the level of preceptor nurses' clinical performance and appropriate internal and external reward to elevate the level of preceptor nurses' Job satisfaction. Therefore, it is needed for us to develop more effective preceptor education program, financial reward, support of colleague nurses and nursing managers, and adjust workload for the purpose of more effective preceptor programs.

In an aging society, there is an increasing possibility of the duplication of the drugs given to patients because they take many kinds of drugs. Among the prescriptions given to the patients who was treated at multiple ambulatory clinics in St. Mary's hospital for one month of September, 2002, in which drugs that has identical or similar effects are prescribed, we analysed and evaluated them by patients' characteristics, kinds of medication, severity of side effects on a case by case basis. More, we assessed the potential additional costs. As a result of this study, the duplication rate turned out to be 6.69% and it was shown that the proportion of the elderly patients over 60 was high. The gastro-intestinal medications took up a large part and most of the cases showed that the danger caused by double taking of medicine was slight, but there were some examples in which the serious side effects were predicted. Expected additional costs were the average 11.349 won and it ranges from the minimum of 56 won to the maximum of 135,720 won. In conclusion, the management of drug histories of the patients who need the plural treatments is very important and the necessity of the individual and professional guidance of taking medicines for the elderly patients is emerged, too.

경제적 및 농업적 장점은 유전자 변형 작물 재배면적의 증가를 가져왔다. 그러나 유전자 변형 작물의 상업적 재배전에 유전자 변형 작물의 인간건강 및 환경에 미칠 잠재적 위해성에 대한 면밀한 검토가 필수적이다. 본 연구에서는 Bt벼의 토양미생물 군집에 미치는 영향을 조사하였다. 토양화학성분을 분석한 결과, Bt벼와 낙동벼 근권토양 간 화학 성분의 유의성 있는 차이는 없는 것으로 조사되었다. 재배전, 재배초기, 최고 분얼기의 토양미생물 군집밀도를 조사했을 때 Bt벼 근권토양의 세균, 방선균, 진균 군집밀도는 낙동 벼와 유사한 수준으로 나타났다. 시기별 DGGE 분석결과 Bt 벼 근권토양 전체미생물상은 낙동벼와 차이가 없는 것으로 조사되었다. Pyrosequencing을 통한 Bt벼와 낙동벼의 미생 물 군집조성을 조사한 결과 주요 미생물상 분포에 있어서도 매우 유사한 양상을 나타내었다. 위의 결과들을 종합해볼 때 Bt 재배에 따른 토양미생물상에 미치는 영향은 미미한 것으로 사료된다. 수확 후 벼 잔존물이 토양환경에 미치는 영향에 대해서는 좀 더 연구가 진행되어야 할 것이다. The cultivation of genetically modified (GM) crops has increased due to their economic and agronomic advantages. Before commercialization of GM crops, however, we must assess the potential risks of GM crops on human health and environment. The aim of this study was to investigate the possible impact of Bt rice on the soil microbial community. Microbial communities were isolated from the rhizosphere soil cultivated with Bt rice and Nakdong, parental cultivar and were subjected to be analyzed using both culture-dependent and molecular methods. The total counts of bacteria, fungi, and actinomycetes in the rhizosphere of transgenic and conventional rice were not significantly different. Denaturing gradient gel electrophoresis (DGGE) analysis of PCR-amplified 16S rRNA genes revealed that the bacterial community structures during cultural periods were very similar each other. Analysis of dominant isolates in the rhizosphere cultivated with Bt and Nakdong rice showed that the dominant isolates from the soil of Bt rice and Nakdong belonged to the Proteobacteria, Cloroflexi, Actinobacteria, Firmicutes, and Acidobacteria. These results indicate that the Bt rice has no significant impact on the soil microbial communities during cultivation period. Further study remains to be investigated whether the residue of Bt rice effect on the soil environment.

Objective: Although the use of broad-spectrum antibiotics in women with preterm premature rupture of membranes (PPROM) is recommended, the optimal duration of antibiotic use is unclear. Recent studies indicated that prolonged antibiotic exposure in very low birth weight neonates was associated with increased risk of bronchopulmonary dysplasia (BPD). However, the impact of duration of prenatal antibiotics exposure is rarely explored. The objective of this study was to investigate the effect of duration of antibiotic use in PPROM and compare the incidence of BPD. Methods: This retrospective study included 402 singleton pregnancies who were admitted to the high risk care unit of our institution due to PPROM between 20+0 and 33+6 week of gestation. We allocated the study population into three groups according to duration of antibiotic use; 7 days (group 1, n=259), 8-14 days (group 2, n=70), ≥ 15 days (group 3, n=73). The maternal baseline characteristics, delivery, and neonatal outcomes were compared among three groups. BPD was defined as a condition requiring oxygen for at least 28 days after birth, and severe BPD was defined as a condition requiring more than 30% oxygen and/or positive pressure at 36 week postmenstrual age or discharge, whichever comes first. Results: The gestational age at admission was lower in groups that used antibiotics longer (p < 0.001). The gestational age at delivery and birthweight showed no significant difference among three groups. Overall, the incidence of BPD and severe BPD was higher in groups that used antibiotics longer (BPD, 19.4% (48/247) in group 1 vs. 32.4% (22/68) in group 2 vs. 30.0% (21/70) in group 3, p = 0.023; severe BPD, 5.7% (14/247) in group 1 vs. 13.2% (9/68) in group 2 vs. 15.7% (11/70) in group 3, p = 0.004, by linear by linear association). Multivariate analysis also demonstrated that severe BPD showed incremental incidence according to longer duration of antibiotic use after adjustment for cofounders including gestational age at admission and delivery (OR [95% confidence interval], 2.17 [0.76-6.21] in group 2, 5.23 [1.45-18.89] in group 3 compared to group 1 as a reference). Conclusion: Our data demonstrated that longer antibiotic use (≥ 15 days) in PPROM was associated with higher risk for severe BPD.
