RESUMO
Objecive To explore modern management and optimization of hospital warehouse slotting with some class A tertiary hospital taken as an example.Methods EIQ_ABC classification method,multi-objective assignment model and genetic algorithm were used to analyze and simulate the data of 126 kinds of medical devices for 20 orders.Results The medical devices were divided into nine categories of Ⅰ A,Ⅰ B,Ⅰ C,Ⅱ] A,Ⅱ B,Ⅱ C,Ⅲ A,Ⅲ B and Ⅲ C.It's suggested that emphasized management and precision slotting storage were carried out for A categories of devices,dedicated storage for B categories and random storage for C categories.At the same time,the layout of the warehouse was optimized according to the importance of the goods so that the important goods were placed near the passageway.Slotting analog simulation diagram was obtained based on multi-objective assignment model of Ⅲ A category medical device.Conclusion Classified management and allocation as well as slotting optimization of medical devices contribute to improving hospital modern management in efficiency,cost and error rate.
RESUMO
OBJECTIVE:To improve the working efficiency of the drug delivery system. METHODS:The kinds of drugs in delivery system and manual dispensing window were adjusted through comparing the number of prescriptions and drug box dis-pensed by the system and manual window in our hospital before adjustment (Jun. 2014),combining with analysis of EIQ(En-try-item-quantity)-ABC. The improvement effect was evaluated through analyzing related index after adjustment(Aug. 2014). RE-SULTS:The data before adjustment showed the workload of the delivery system was lower than that of manual delivery in term of the number of drug box (P=0.000),and they were similar in term of the number of prescription (P=0.122). The drug delivery system was significantly better than manual delivery in terms of two indexes after resetting the type of drugs in the system(P=0.000). CONCLUSIONS:Optimized delivery system can effectively improve the working efficiency.
RESUMO
La producción de alimentos se basa en el uso de diferentes tecnologías agrícolas, que pueden derivar en conflictos entre medioambiente y agricultura. Es significativo estudiar el impacto ambiental de las nuevas tecnologías aplicadas a la agricultura, la más importante de las cuales es la transgénesis. Este trabajo se realizó en la zona algodonera del municipio del Espinal, departamento del Tolima, para la cosecha de algodón del primer semestre de 2009, usando las metodologías de Brookes y Barfoot (2006) y Kovach y colaboradores (1992). Se estudió el efecto ambiental de la aplicación de agroquímicos y el uso de maquinaria agrícola en cultivos de algodón transgénico y convencional. Se recogió información mediante encuestas en veinte fincas productoras de algodón. El análisis de las encuestas se realizó de forma descriptiva, determinando diferencias de tipo cuantitativo y cualitativo para los predios que utilizan la tecnología convencional o la tecnología transgénicas (doble gen, Bt/RR), para luego realizar una correlación con el Enviromental Index Quotient (EIQ). No se encontraron diferencias entre el EIQ de campo de las dos tecnologías, aunque la tecnología transgénica tiene ventajas ambientales en el control de algunas plagas de lepidópteros. En relación con el uso de maquinaria agrícola, se encontró que la tecnología convencional genera menor liberación de CO2, gas de efecto invernadero. La metodología de Brookes y Barfoot puede adaptarse para estudios comparativos de tecnologías agrícolas en países tropicales.
Food production is based on the use of various agricultural technologies, which can lead to conflicts between environment and agriculture. It is important to study the environmental impact of new technologies applied to agriculture, the most important of which is transgenesis. This work was carried out in the cotton belt of the town of Espinal, Tolima Department for the cotton crop in the first half of 2009, through methodologies Brookes & Barfoot (2006) and Kovach et al (1992). We studied the environmental impact of pesticide application and use of agricultural machinery for cultivation of transgenic and conventional cotton. Information was collected through surveys of 20 farms producing cotton. The analysis of the survey was conducted descriptively, by determining differences in quantitative and qualitative for the sites that use conventional technology, and transgenic (Bt gene and double RR / RR), and then make a correlation with the Environmental Index Quotient (EIQ). No differences were found between the fields EIQ the two technologies, although transgenic technology has environmental advantages in the control of some lepidopteran pests. In connection with the use of agricultural machinery, was found to conventional technology generates less release of CO2, greenhouse gas. The Brookes and Barfoot methodology could be adapted in comparative studies of agricultural technologies in tropical countries.
