Objective:To rapidly assess the effectiveness,safety,economy,and applicability of Shaoma Zhijing granule(SZG)for the treatment of children with tic disorders(TD),and provide currently available best evidence for decision-makers of health policies.Methods:We conducted a rapid health technology assessment(RHTA)to explore the value of SZG.A systematic literature search in eight literature databases and on three clinical trial registration platforms was performed.The literature was screened according to eligibility criteria.The screening process and data extraction were conducted by two reviewers,and the quality of the literature was also assessed.The results were summarized,analyzed,and presented in tables or figures.Results:A total of five randomized controlled trials(RCTs)were included in this study,of which one was published in English(in the Journal of Child Psychology and Psychiatry)and four in Chinese journals.The overall risk of bias for the five RCTs was evaluated as“some concerns.”SZG monotherapy or in combi-nation with tiapride was better than tiapride alone in improving traditional Chinese medicine(TCM)syndromes and tic symptoms,with a daily cost of¥67.50e107.22.Adverse events were mainly related to the digestive,respiratory,and neurological systems,but all were mild.Conclusion:Overall,the current RHTA of published,peer-reviewed literature has located a small body of evidence evaluating the use of SZG for the treatment of TD in children.SZG has effects on improving TCM syndromes and tic symptoms;the daily cost is¥67.50e107.22;and all adverse events are mild.High-quality studies with long-term follow-up should be conducted,so as to provide local evidence and consistently guide and improve scientific decision-making. 展开更多

Urbanization strategic environmental assessment (SEA) is an effective instrument to enhance the harmo-nious development of urban complex system, integrating of environment and development in decision-making. Ur-banization strategic environmental assessment integration technology system (SEA-ITS) is composed of "3S" (RS, GIS and GPS), environmental expert system and environmental model system, coupling with appropriate SEA working process closely. In this paper, the structure and components of SEA-ITS are analyzed based on Chinese characteristics, meanwhile methods to fulfill the following system functions are discussed: urbanization SEA in-quiring, analysis, discrimination, assessment, prediction, decision-making and output. Moreover, methods and tech-nologies employed in different urbanization SEA hierarchies are summarized. As a case study, urbanization SEA-ITS is applied in Changchun City to solving complex real problems. Methods such as system dynamics and grey cluster are adopted to achieve the environmental impact assessment on the eco-industrial system planning. It is revealed that the system designed is capable of reflecting the dynamic behavior of eco-industrial system under different sce-narios, meanwhile accomplishing strategy optimization and supplying scientific reference. The 4th strategy, namely concerning on economy increase and its interaction with science, technology and environment progress, would have the best efficiency. Further, more attention should be paid to the secondary development of integration techniques and function modification system of urbanization SEA-ITS. 展开更多

Slope excavation is one of the most crucial steps in the construction of a hydraulic project. Excavation project quality assessment and excavated volume calculation are critical in construction management. The positioning of excavation projects using traditional instruments is inefficient and may cause error. To improve the efficiency and precision of calculation and assessment, three-dimensional laser scanning technology was used for slope excavation quality assessment. An efficient data acquisition, processing, and management workflow was presented in this study. Based on the quality control indices, including the average gradient, slope toe elevation, and overbreak and underbreak,cross-sectional quality assessment and holistic quality assessment methods were proposed to assess the slope excavation quality with laserscanned data. An algorithm was also presented to calculate the excavated volume with laser-scanned data. A field application and a laboratory experiment were carried out to verify the feasibility of these methods for excavation quality assessment and excavated volume calculation. The results show that the quality assessment indices can be obtained rapidly and accurately with design parameters and scanned data, and the results of holistic quality assessment are consistent with those of cross-sectional quality assessment. In addition, the time consumption in excavation quality assessment with the laser scanning technology can be reduced by 70%e90%, as compared with the traditional method. The excavated volume calculated with the scanned data only slightly differs from measured data, demonstrating the applicability of the excavated volume calculation method presented in this study. 展开更多

Although a key tenant of the Sustainable Development Goals is to achieve universal health coverage,the global drug gap persists-cver a third of the global population lack access to essential medicines.Without access to affordable drugs,people have worse health outcomes,higher medical expenses,and productivity loss,pushing them into poverty.Health technology assessments(HTAs)offer an opportunity to decrease the global drug gap and increase access to essential medicines by overcoming barriers to medicine access.These barriers include drug procurement,drug affordability for payers and patients,a patienfs ability to obtain essential medicines,and health system capacity.Using HTAs can therefore close the global drug gap by increasing access to affordable essential medicines.In turn,people have better health outcomes,spend less money on medical care,and can have better productivity.Ultimately,use of HTAs can lift the population out of poverty and force fewer people into poverty by creating better health outcomes at affordable prices. 展开更多

Facing the ethical potentials of technology, there appears a new trend in technology assessment (TA) recently, which is techno-ethics embedment that aims embed ethical perspectives within the process of assessing and developing new technologies. There are two basic dimensions of this trend: the role of ethics and the status of technology. By referring these dimensions, I articulate two different TA modes of the techno-ethics embedment: One is the ethical technology assessment (eTA) that appears as a combination of an ethical judge with the objective technological force, while the other is the combination of an engaged ethical participant with an active technological mediator. Moreover, there is an ideal status of this trend that is an engaged ethical participant with an active technological mediator. As the thought of technology accompaniment shows, both the "agency" of human and technology will be embodied to the most in this ideal status of techno-ethics embedment. 展开更多

Coal occupies a dominant position in China's national economy and is an essential energy source for future industrial development. To inform the efficient and sustainable development of the coal industry, this paper analyzes the sources of strategic risk for coal science and technology enterprises using 3 first-class indicators, 10 second-level indicators, and 37 observation points established through the existing research literature and experience. Moreover, in accordance to the obtained initial index data, the selected indicators have been tested and screened using reliability and membership degree analyses to remove redundant variables, avoid juxtaposition of risk factors at different levels, and reduce the influ- ence of some tiny risk factors for enterprise strategic risk. Then, factor analysis of external environment factor sub-scale was carried out. Factors are extracted according to a standard characteristic value greater than 1. Variables with high coefficients are classified into one factor category; and finally, 3 first-class indicators. 8 second-level indicators, and 37 observation noints are reconstructed. 展开更多

Global governance is often equated with international institutions such as the United Nations and the World Bank that were established after World War II to address problems transcending national borders. While these institutions incorporate norms of representative democracy that evolved in national societies, their legitimacy is often questioned on grounds of limited effectiveness and remoteness from the citizens they purportedly serve. The arguments of many democratic theorists that deliberation among ordinary citizens can legitimize policies that heed these views thus bear important implications for global governance. In this paper, the possibility and different ways that civil society enhancing public participation, transparency and accountability in global governance are addressed. The empirical focus will be on the world's first global deliberation--WWViews (world wide views on global warming) that was held in 38 countries with all inhabited continents in 2009. The social drivers that encourage innovation in global democratic governance are analysed, as the main successes and challenges of WWViews and sketch three scenarios of the future of deliberative global governance are based on the experiences and plans around global citizen participation. The authors argue that despite some challenges, such as ensuring high quality of deliberation in highly variant policy cultural contexts and building policy pathways conducive to political impact, the prospects of deliberation in helping solve global environmental and policy problems are high, and likely to see cumulative progress in the near future. 展开更多

TC-RF (transcatheter radiofrequency) ablation has an important role in the treatment ofSVA (supraventricular arrhythmias). The indication to TC-RF ablation is usually made to improve the patient's quality of life through the elimination of the arrhythmic substrate. The objective of this study is to make a brief review of the literature and to report the Electrophysiology Unit experience of the Cardiovascular Department of the University Hospital of Trieste. From the study, it can be found that about one thousand of patients are visited annually in the Cardiovascular Department of the University Hospital of Trieste (1,019 ± 71/year over the past five years). The acute success rate of atrial fibrillation and flutter ablation procedures was respectively 93.9% and 97.9% with a relapse rate of 30% and 10% at 12 month. Accessory pathways and nodal atrio ventricular re-entry tachycardia ablation procedures had an acute success rate of respectively 91.1% and 96.6% with a relapse rate of 10% at 12 months. The overall complication rate was 5%. Catheter ablation is an effective therapy for SVA treatment. It can often be definitive, and it is generally superior to drug therapy, with a low complication rate. The improvement in patients' quality of life is associated with a reduced need for access to health services. 展开更多

A significant proportion of power generation stems from coal-combustion processes and accordingly represents one of the largest point sources of CO_(2)emissions worldwide.Coal power plants are major assets with large infrastructure and engineering units and an operating life span of up to 50 years.Hence,any process design modification to reduce greenhouse gas emissions may require significant investment.One of the best options to utilize existing infrastructure is to retrofit the power station fleet by adding a separation process to the flue gas,a practice known as postcombustion capture(PCC).This review examines the recent PCC development and provides a summary and assessment of the state of play in this area and its potential applicability to the power generation industry.The major players including the various institutes,government,and industry consortia are identified along with flue gas PCC demonstration scale plants.Of the PCC technologies reviewed,amine-based absorption is preeminent,being both the most mature and able to be adapted immediately,to the appropriate scale,for power station flue gas with minimal technical risk.Indeed,current commercial applications serve niches in the merchant CO_(2)market,while a substantial number of smaller scale test facilities are reported in the literature with actual CO_(2)capture motivated demonstrations now commencing.Hybrid membrane/absorption systems,also known as membrane contactors,offer the potential for the lowest energy requirements,possibly 10%of current direct scrubbers but are at an early stage of development.Other methods being actively pursued as R&D projects include solid absorbents,solid adsorbents,gas membrane separators,and cryogenic separation.The variety and different maturities of these competing technologies make technical comparison largely subjective,but useful insights could be gained through the development and application of econometric techniques such as‘real options’within this context.Despite these limitations,it is clear from this review that amine scrubbing is likely to be adapted first into the existing power station fleet,while less mature technologies will grow and become integrated with the development of future power stations. 展开更多

There is an increase in annual waste generation due to urbanization,industrialization,and population growth.The waste management crisis in developing countries and its complexity from region to region has inspired extensive research work in this area.Poor management not only results in environmental hazards,but it also causes significant socio-economic losses.Due to the absence of comprehensive studies on waste to energy(WTE)assessment,this study assesses and reports the merits of alternative technologies for converting WTE in small and medium-size districts.Quantitative analysis for waste collection data in this study uses a pilot study approach to provide useful insights and waste classification.A cantonment district of Pakistan(Wah Cantt)has been used as a case study for performing a technological and economic assessment of energy generation through the use of thermal and biological treatment processes.A mathematical modeling approach has been adopted for generating an economic value of each technology through which this waste can be processed.Further,the levelized cost of energy(LCOE)based assessment has been performed to provide a methodological framework for selecting the most feasible WTE technology in a small or medium-size district.Based on the model results,anaerobic digestion appears to be the most sustainable technology due to the organic nature of waste in Wah Cantt,land legislation,and availability of area to install a waste plant.Considering all the waste collected,the district can generate approximately 14.4 MW of energy through thermal treatment,19,110 m^(3) of daily biogas through anaerobic digestion,and 5 million tons of fertilizer through composting.Hence,if a proper supply chain is established for converting a portion of Pakistan’s annual waste generation,a significant amount of waste energy potential can be restored. 展开更多

Targeting the net-zero emission(NZE)by 2050,the hydrogen industry is drastically developing in recent years.However,the technologies of hydrogen upstream production,midstream transportation and storage,and downstream utilization are facing obstacles.In this paper,the development of hydrogen industry from the production,transportation and storage,and sustainable economic development perspectives were reviewed.The current challenges and future outlooks were summarized consequently.In the upstream,blue hydrogen is dominating the current hydrogen supply,and an implementation of carbon capture and sequestration(CCS)can raise its cost by 30%.To achieve an economic feasibility,green hydrogen needs to reduce its cost by 75%to approximately 2$/kg at the large scale.The research progress in the midterm sector is still in a preliminary stage,where experimental and theoretical investigations need to be conducted in addressing the impact of embrittlement,contamination,and flammability so that they could provide a solid support for material selection and largescale feasibility studies.In the downstream utilization,blue hydrogen will be used in producing value-added chemicals in the short-term.Over the long-term,green hydrogen will dominate the market owing to its high energy intensity and zero carbon intensity which provides a promising option for energy storage.Technologies in the hydrogen industry require a comprehensive understanding of their economic and environmental benefits over the whole life cycle in supporting operators and policymakers. 展开更多
