BACKGROUND Regarding the incidence of malignant tumors in China,the incidence of liver cancer ranks fourth,second only to lung,gastric,and esophageal cancers.The case fatality rate ranks third after lung and cervical cancer.In a previous study,the whole-process management model was applied to patients with breast cancer,which effectively reduced their negative emotions and improved treatment adherence and nursing satisfaction.METHODS In this single-center,randomized,controlled study,60 randomly selected patients with liver cancer who had been admitted to our hospital from January 2021 to January 2022 were randomly divided into an observation group(n=30),who received whole-process case management on the basis of routine nursing mea-sures,and a control group(n=30),who were given routine nursing measures.We compared differences between the two groups in terms of anxiety,depression,the level of hope,self-care ability,symptom distress,sleep quality,and quality of life.RESULTS Post-intervention,Hamilton anxiety scale,Hamilton depression scale,memory symptom assessment scale,and Pittsburgh sleep quality index scores in both groups were lower than those pre-intervention,and the observation group had lower scores than the control group(P<0.05).Herth hope index,self-care ability assessment scale-revision in Chinese,and quality of life measurement scale for patients with liver cancer scores in both groups were higher than those pre-intervention,with higher scores in the observation group compared with the control group(P<0.05).CONCLUSION Whole-process case management can effectively reduce anxiety and depression in patients with liver cancer,alleviate symptoms and problems,and improve the level of hope,self-care ability,sleep quality,and quality of life,as well as provide feasible nursing alternatives for patients with liver cancer. 展开更多

Medical education is an important cornerstone for the development of healthcare,and medical humanities education,as an integral part of medical education,plays an irreplaceable role in cultivating people’s health guardians with high medical ethics.We adopted the method of stratified random sampling to select 309 students and 107 faculty members from three independent medical colleges in Sichuan province as the research subjects and distributed questionnaire surveys investigating in three dimensions:overall cognition of medical humanities,evaluation of medical humanistic qualities,and the current situation of medical humanities education,supplemented by an in-depth literature review and interviews with subject matter experts.We found that“tech-centrism”still has a great influence,the self-evaluation of medical students’humanistic quality is generally not high,the educational concept of“emphasizing professional skills over morality”of faculty and staff is still quite prevalent,and there is still the“last mile”phenomenon in medical humanities education.In order to promote the integrated development of“new medicine”and“new liberal arts”and break the barriers of“tech-centrism”and“instrumental rationality,”it is necessary to change the educational concept and strengthen the education of all employees,break through the bottleneck of internships and strengthen the whole process of education,integrate educational resources and strengthen all-round education,improve the incentive mechanisms,strengthen the assessment methods,and provide Chinese wisdom and Chinese solutions for the development of medical humanities education. 展开更多

In response to the lack of global quantitative research on the potential and scale prediction of CO_(2) capture,utilization and storage(CCUS)in China under the background of carbon peak and carbon neutrality goals,this study predicts the future economic costs of different links of ccUS technologies and the carbon capture needs of different industries in the scenario of fossil energy continuation.Based on the CO_(2) utilization and storage potential and spatial distribution in China,a cost-scale calculation model for different regions in China in 206o is constructed to predict the whole-process economic cost and its corresponding scale potential of CCUs.The results show that a local+remote storage mode is preferred,together with a local utilization mode,to meet China's 27×10^(8)t/a CO_(2) emission reduction demand under the scenario of fossil energy continuation.Specifically,about 5×10^(8) t CO_(2) emission is reduced by capture utilization,and the whole-process cost is about-1400-200 RMB/t;about 22×10^(8) t CO_(2) emission is reduced by capture storage,and the whole-process cost is about 200-450 RMB/t.According to the model results,it is recommended to develop the chemical utilization industry based on P2X(Power to X,where X is raw material)technology,construct the CcUs industrial cluster,and explore a multi-party win-win cooperation mode.A scheme of national trunk pipeline network connecting areas connecting intensive emission reduction demand areas and target storage areas is suggested.The emission reduction cost of thermal power based on CCUS is calculated to be 0.16 RMB/(kW.h). 展开更多

Landing gear lower drag stay is a key component which connects fuselage and landing gear and directly effects the safety and performance of aircraft takeoff and landing. To effectively design the lower drag stay and reduce the weight of landing gear, Global/local Linked Driven Optimization Strategy(GLDOS) was developed to conduct the overall process design of lower drag stay in respect of optimization thought. The whole-process optimization involves two stages of structural conceptual design and detailed design. In the structural conceptual design, the landing gear lower drag stay was globally topologically optimized by adopting multiple starting points algorithm. In the detailed design, the local size and shape of landing gear lower drag stay were globally optimized by the gradient optimization strategy. The GLDOS method adopts different optimization strategies for different optimization stages to acquire the optimum design effect. Through the experimental validation, the weight of the optimized lower dray stay with the developed GLDOS is reduced by 16.79% while keeping enough strength and stiffness, which satisfies the requirements of engineering design under the typical loading conditions. The proposed GLDOS is validated to be accurate and efficient in optimization scheme and design cycles. The efforts of this paper provide a whole-process optimization approach regarding different optimization technologies in different design phases, which is significant in reducing structural weight and enhance design tp wid 1 precision for complex structures in aircrafts. 展开更多

Gradient distributions of temperature and deformation(GDTD)are crucial for achieving dual-performance discs of titanium alloys which is required by the service environment of aeroengine.However,heating,cooling and deforming sequence in the whole process of the titanium disc forming,which leads to difficulties for achieving GDTD due to a lot of parameters.To solve this problem,a whole-process model of the titanium disc forming for GDTD has been established.In the model,heating and cooling via heat radiation,conduction and convection,and deforming by local loading with mold chilling are all considered.Experiments on heating and cooling as well as deforming were carried out by using a furnace and the Gleeble-3500 machine.The experimental data are used to determine thermal parameters and constitutive relations of the IMI834 titanium alloy,and then to verify the reliability of the model.Then the model was used to simulate the evolution rules of temperature and deformation of the titanium disc.The results show that the heating surface,furnace temperature,billet profile and loading rate play the core role for the control of GDTD,and thus a set of parameters were determined.Therefore,this work provides a base for developing a new forming technology of the dual-performance titanium discs with the approach of local heating and local loading. 展开更多

The concept of whole-process people’s democracy can be analyzed in terms of four the rule of law dimensions:continuous democracy,authentic democracy,extensive democracy and consultative democracy.Continuous democracy means that democracy provides a continuous and uninterrupted mechanism in terms of stage,time and space,which can ensure the continuous participation of the people in the management of state and social affairs.Authentic democracy is not only embodied creation of opportunities and conditions for the people to have more channels and methods of participation in the management of state and social affairs,but is also reflected in the process of democratic practice,including the protection of legitimate rights and interests of the minority.Extensive democracy means that the people are fully and deeply involved in the management of state and social affairs as well as their own affairs,from the operation of the state system to social life at the community level,and from pre-election to post-election.Consultative democracy is a means of realizing people’s democracy in the whole process.It applies consultation and seeks truth,aiming at building consensus.Moreover,it integrates various channels of consultation,and integrates democracy into all aspects of the work of the Communist Party of China(CPC)and government and in all aspects of the people’s political and social life. 展开更多

Whole-process people’s democracy profoundly reflects the features of socialist democracy with Chinese characteristics,and comprehensively and systematically reveals the concept of people’s democracy as providing important mechanisms of national and social governance.Based on the traditional democratic understanding of democracy as majority rule,whole-process people’s democracy emphasizes the universality and extensive range of democratic governance,but also has the natural value defects of democratic value itself.Therefore,we must organically combine democracy with the values of the rule of law and human rights,to build a well-defined governance order based on people’s democratic value.The whole process in the“whole-process people’s democracy”has really resolved the situation of people’s“absence”from many links of state power operation caused by over-emphasizing the election-democracy in the Western capitalist democratic system.Through the people’s extensive participation and effective supervision,the state power operation mechanism based on the fundamental political system,the people’s congress system,has been ensured to be always in the framework of people’s democratic governance.This effectively realizes the people’s sovereignty and is consistent with the declaration that“all power in the People’s Republic of China(PRC)belongs to the people,”stipulated in the Constitution of China.To improve the governance efficiency of whole-process people’s democracy in practice,we must bring it onto the rule of law,and use the rule of law philosophy and methods to reasonably and effectively resolve all kinds of theoretical and practical problems. 展开更多

Traditional calibration methods mostly focus on the calibration of detection systems while the calibration from the sampling and pre-condition systems to the detection system is usually ignored.In this regard,a Primary Standard Aerosol Mass Concentration Calibration System(PAMAS)is developed for the whole-process calibration of time-resolved aerosol measurement instruments.PAMAS is composed of a particle generation chamber,an ultrasonic atomizer,a dilution system,and a syringe pump.It is designed to steadily generate standard aerosol particles of known concentrations(≤250μg/m^(3)),chemical compositions,and stable particle size distributions.Monodispersed aerosol can be generated in the size range of hundreds of nanometers to several micrometers with a narrow size distribution.The generated particles with different compositions generated by PAMAS have been well verified by the filter-based gravimetric method,yielding accuracy and R^(2) of more than 95%and 0.999 in a wide concentration range.The response time by changing the target concentration of reference particles is 1-2 min.PAMAS has been applied to various types of time-resolved aerosol measurement instruments,including particle mass concentration monitors(Beta Attenuation and Tapered Element Oscillating Microbalance),online Ion Chromatograph,and semi-continuous OCEC carbon aerosol analyzer.Very consistent results between PAMAS and calibrated instruments can be obtained if the instruments are functioning well.As for instruments with certain technical issues,PAMAS can serve as a good tool for performance evaluation and quality assurance of the instruments and the accuracy of the measurement data can be adjusted based on the calibration results. 展开更多

The iron and steel industry is not only an important foundation of the national economy,but also the largest source of industrial air pollution.Due to the current status of emissions in the iron and steel industry,ultra-low pollutant emission control technology has been researched and developed.Liquid-phase proportion control technology has been developed for magnesian fluxed pellets,and a blast furnace smelting demonstration project has been established to use a high proportion of fluxed pellets(80%)for the first time in China to realize source emission reduction of SO_(2)and NO_(x).Based on the characteristics of high NO_(x)concentrations and the coexistence of multiple pollutants in coke oven flue gas,low-NO_(x)combustion coupled with multi-pollutant cooperative control technology with activated carbon was developed to achieve efficient removal of multiple pollutants and resource utilization of sulfur.Based on the characteristics of co-existing multiple pollutants in pellet flue gas,selective non-catalytic reduction(SNCR)coupled with ozone oxidation and spray drying adsorption(SDA)was developed,which significantly reduces the operating cost of the system.In the light of the high humidity and high alkalinity in flue gas,filter materials with high humidity resistance and corrosion resistance were manufactured,and an integrated pre-charged bag dust collector device was developed,which realized ultralow emission of fine particles and reduced filtration resistance and energy consumption in the system.Through source emission reduction,process control and end-treatment technologies,five demonstration projects were built,providing a full set of technical solutions for ultra-low emissions of dust,SO_(2),NO_(x),SO_(3),mercury and other pollutants,and offering technical support for the green development of the iron and steel industry. 展开更多

Recent measures of carbon dioxide emissions from the steel industry of China have indicated a high rate of total CO2 emissions from the industry, even compared to the rest of the world. So, CO2 emission reduction in China's steel industry was analyzed, coupling the whole process and scenarios analysis. First, assuming that all available advanced technologies are almost adopted, this study puts forward some key potential-sectors and explores an optimal technical route for reducing CO2 emissions from the Chinese steel industry based on whole process analysis. The results show that in the stages of coking, sintering, and iron making, greater potential for reducing emissions would be fulfilled by taking some technological measures. If only would above well-developed technolo- gies be fulfill, the CO2 emissions from 5 industry production stages would be reduced substantially, and CO2 emissions per ton of steel could be decreased to 1.24 (ton/ton-steel) by 2020. At the same time, the scenarios analysis indicates that if mature carbon-reducing technol- ogies are adopted, and if the difference between steel output growth rate and the GDP growth rate could be controlled below 3%, CO2 emissions from China's steel industry would approach the goal of reducing CO2 emissions per GDP unit by 40%-45% of the 2005 level by 2020. This indicates that the focus of carbon dioxide emissions reduction in China lies in policy adjustments in order to enhance technological application, and lies in reasonably controlling the pace of growth of GDP and steel output. 展开更多
