However, during the process of forming the technology standard alliance, it is a focus for members in the alliance to take control over others. How to construct a scientific and reasonable decision model of control over technology standard alliance is closely related to each enterprise member＇s interest. Under the condition that the risk is neutral, the paper explored necessary and sufficient conditions of knowledge sharing and the most endeavor among enterprise members through constructing a decision model of control over technology standard alliance, and put forward that the joint control model was the best decision model for constructing the technology standard alliance.展开更多

With a gradual progress in standardization, this field presents new development trends and features. Based on latest progresses in standardization promoted by ITU-T, TISPAN and 3GPP, new technologies concerned with resource control are introduced. Considering the problems faced in standardization deployment, relevant resource control functions are also analyzed in this article.展开更多

Many health facilities have not implemented them to an acceptable level. The purpose of the study is to report progress of improvement in health facilities readiness to implement standard precautions for infection prevention and control based on SARA reports. Methods: We generated mean scores of all standard precautions each year and calculated their standard deviations, variances and confidence intervals. One-way ANOVA was used to determine if the mean scores were equal. Finally, the trend of improvement in health facilities readiness to implement the standard precautions was generated. Results: A total of nine standard precautions were reported in SARA reports for 2012, 2017 and 2020. The mean scores of the standard precautions were 52.22% in 2012, 64.55% in 2017 and 69.66% in 2020. The overall trend showed an increase in health facilities readiness to implement standard precautions, although the mean scores were not statistically different (p-value 0.3217). Conclusion: SARA surveys conducted in Tanzania in 2012, 2017 and 2020 have shown an overall increase in health facilities readiness to implement standard precautions. Safe final waste disposal was being done in fewest facilities while single-use or auto-disable syringes were in most facilities that were sampled in all years. SARA surveys may be a useful way to evaluate Infection Prevention and Control adherence in health facilities.展开更多

However, the current quality standard research lacks top-level design and systematic design,mostly based on specific technologies or evaluation methods. To resolve the challenges and questions of quality control of TCMs, a brand-new quality standard system, named "iVarious", was proposed. The system comprises eight elements in a modular format. Meaning of every element was specifically illustrated via corresponding research instances. Furthermore, frankincense study was taken as an example for demonstrating standards and research process, based on the "i Various" system. This system highlighted a holistic strategy for effectiveness,security, integrity and systematization of quality and safety control standards of TCMs. The establishment of"i Various" integrates multi-disciplinary technologies and progressive methods, basis elements and key points of standard construction. The system provides a novel idea and technological demonstration for regulation establishment of TCMs quality standards.展开更多

Results:Post-intervention,the percentage of studied nurses who always practiced increased in every item of TB infection control practice(6 items) and standard precaution(9 items) when compared with the preintervention period.Both mean scores were significantly higher than those before intervention(5.0±1.0 vs 4. 4±1.1,and 7.6±1.3 vs 6.7±1.5,P【0.001,respectively).As well as,bacterial and fungal counts in air samples collected from every studied ward decreased after implementing the intervention,for example, mean of bacterial counts in OPD decreased from 387.8±249.5 cfu/m^3 to 194.4±134.3 cfu/m^3.Additionally, there was no air sample with high level of bacterial and fungal counts,whereas,3.7 -22.2%of air samples collected before intervention had high level of bacterial counts(】500 cfu/m^3).Conclusion:Two-day training program and management of the ward environment could improve the scores of TB infection control practices and the standard precaution among studied nurses and reduce the microbial counts in air samples collected from the studied wards.展开更多
