ABSTRACT
Objective To explore the effective nursing and long-term safety training mode, early intervention on safety awareness of junior nurses, regulate the safety behavior, ensure patient safety. Methods The ideas and methods of HSE management system (health, safety and environment trinity management system) were introduced, from training needs research, safety courses design, safety behavior training, training process management,safety knowledge clinical application and training quality control implementation of systematic management.From 2013 to 2014 low seniority nurses safety training for 2 years, including new hospital nurse per year.Taking the self contrast before and after experimental design, safety knowledge to master the situation, the nurse's satisfaction and quality of care and safety management before and after training were compared. Results The actual class qualified rate and safety knowledge awareness and the excellent and good rate of safety skills assessment after training were 80.10%(157/196), 92.34%(181/196),96.43%(189/196), which were higher than those of 65.30%(128/196), 81.63%(160/196), 88.78%(174/196) before training, and the differences were statistically significant, χ2=10.81,9.94,7.07,P<0.01. The overall satisfaction of the nurses for safety training was 92.35%(181/196)after training, which was higher than that of 80.61%(158/196)before training, the difference was statistically significant, χ2=16.37, P < 0.01.The qualified rate of nursing quality for the critically ill patients after training was 90.13%(210/233), which was higher than that of 81.48%(176/216) before training, the difference was statistically significant, χ2= 6.94, P < 0.01. The patient safety and quality, the quality of nursing records were 95.81%(206/215), 95.29%(688/722) after training, respectively, which were higher than those of 89.60%(181/202), 85.10%(577/678) before training, the differences were significant, χ2=5.98,4.17, P<0.05. Conclusions Improved safety training is normative, practicability and maneuverability, safety behavior norms, improve the risk identification and emergency handling ability, reduce nursing risk, close to the clinical need for safety management, safety training for nurses to provide the basis for sustainable development.
ABSTRACT
This work was carried out during one year in a fish pond to evaluate the effect of water quality in a plankton community according to the adopted management. High densities of Euglenophyceae, Chlorophyceae and Cyanobacteria were associated with high nitrate levels (1 to 210 mg.L-1). Cell densities of Cyanobacteria over 90 ind.m³ × 10³ (85.5%) occurred when nitrate concentrations approximated 210 mg.L-1, total phosphorus less than 160 mg.L-1 and temperature above 25 °C. High density of Rotifera was associated with high density of Cyanobacteria (December). Only Trichocerca sp. among the Rotifera species was constant in all sampled sites, whereas Diaphanosoma birgei, ranging between 4 and 342 ind.L-1 (0.7 and 2.4%) during the study period, was the most representative among the Cladocera species. Results show that water quality management in the fish pond had a direct influence on the plankton population due to the shallowness of the environment, large nutrient discharges through feed, fertilizing, fish waste. In fact, they contribute towards the appearance of undesirable plankton organisms.
O presente estudo foi realizado durante um ano em viveiro de produção de peixes, com a finalidade de avaliar o efeito da qualidade da água na comunidade planctônica em função do manejo adotado. Maiores densidades de Euglenophyceae, Chlorophyceae e Cyanobacteria estiveram associadas aos elevados teores de nitrato (1 a 210 mg.L-1). Densidades de Cyanobacteria acima de 90 ind.m³ × 10³ (85,5%) ocorreram quando as concentrações de nitrato estiveram ao redor de 210 mg.L-1, fósforo total menor que 106 mg.L-1 e temperatura acima de 25 °C. Elevada densidade de Rotifera também esteve associada às altas densidades de Cyanobacteria (dezembro). Dentre os organismos zooplanctônicos, os Rotifera foram os mais abundantes e somente Trichocerca sp. foi constante em todos os pontos amostrados. Dentre os Cladocera, a espécie mais representativa foi Diaphanosoma birgei, variando de 4 a 342 ind.L-1 (0,7 e 2,4%) durante o período de estudo. Os resultados mostram que qualidade da água e o manejo empregado neste viveiro apresentaram influência direta na população planctônica, em função da baixa profundidade e constante carga de nutrientes que são incorporados no viveiro por meio de alimentos, fertilizantes e fezes de peixes, que contribuem para o aparecimento de organismos planctônicos não desejáveis.
ABSTRACT
This study was conducted to evaluate the effectiveness of a floor gully come with grating to prevent the oviposition of Aedes aegypti in the floor trap. In order to conduct the test, two containers were placed into a mosquito cage (30 cm × 30 cm × 30 cm). Both containers were filled with declorinated seasoned tap water and covered with floor gully c/w grating and normal floor gully, respectively. A total of 50 gravid Ae. aegypti females were then released into the cage and left for a week. All the eggs obtained from the test were allowed to remain inside the containers for the eggs to hatch. The number of hatched larvae was counted and recorded. Five replicates were conducted concurrently. There was a significant difference of Ae. aegypti larvae obtained between container with floor gully c/w grating and normal floor gully (p <0.05). A total of 96.41% reduction of Ae. aegypti larvae was obtained in the container with floor gully c/w grating compared with the normal floor gully, indicating that the floor gully c/w grating used in this study was able to prevent oviposition of Ae. aegypti in holding water.
