[Method] Based on the Driving Force-State-Response model, expert weight method and entropy method were used to determine weight, and then the composite indexes of environmental effects （CIE for short） were calculated. [Result] During the period from 1980 to 2010, CIE had presented a rising trend whether expert weight method or entropy method in the study area, while the CIE presents downtrend basically in lower reaches. [Conclu- sion] It was the arable land expansion in middle reaches that led to serious land degradation in lower reaches, and may endanger ecosystem safety in Hotan River green corridor. Therefore, it is suggested that the agricultural land use should be restructured, such as reducing the sown areas of some crops with large amount of water consumption. Meanwhile, the effective measures should be taken to distribute water resources and utilize them reasonably. In addition, the oasis-desert ecotone, as well as the groundwater resources, should be also protected.展开更多

OBJECTIVE： To observe the comprehensive effect of developing stroke rehabilitation unit based on the facility of secondary hospital and its feasibility. DESIGN： Non-randomized concurrent controlled observation SETTING： Department of Neurology, Beijing Longfu Hospital PARTICIPANTS： Totally 264 stroke reconvalescents who suffered stroke for 7 days and received treatment in the Department of Neurology, Beijing Longfu Hospital during June 2003 to June 2005 were involved in the study. All the involved patients were confirmed by CT or MRI. The patients were scored by using Modified Edinbergh-Scandinavia stroke scale （SSS） 〉 16 points. Written informed consents were obtained from all the patients. The patients were assigned into 2 groups according to the willing of patients and their relatives： （1）treatment group, in which, there were 134 patients, 76 males and 58 females, aged 43 to 74 years; cerebral infarction was found in 116 cases and cerebral hemorrhage in 18 cases;（2） control group, in which, there were 130 patients, 66 males and 64 females, aged 45 to 77 years, cerebral infarction was found in 115 cases and cerebral hemorrhage in 15 cases. There were significant differences in baseline data of the patients between two groups. METHODS： A same basic treatment was conducted in the patients of the two groups. （1） Patients in the treatment group admitted to stroke rehabilitation unit and received comprehensive rehabilitation treatment. The rehabilitation flow-sheet： randomization-letting the patients of treatment group go into the unit-making comprehensive assessment in the initial stage-making therapy plan-talking with patients and their other family members-general rehabilitation-making metaphase assessment-adjusting therapy plan-making final assessment-letting the patients discharge and doing follow-up visits. （2） The patients in the control group admitted to common wards, and they were encouraged to do activities by themselves in the early stage, but did not receive rehabilitation training under the instructions from professional physicians. MAIN OUTCOME MEASURES： The following assessments were conducted on admission and 7 and 28 days after admission： （1） Severity of stroke and motor function： scored as 0 to 45 points by SSS, the higher points, the severer damage. （2）Activities of daily living： Evaluated by Barthel index, 110 points in total, 110 points meant normal, 0 point meant extremely poor. （3）Mental status： evaluated by Hopkin＇s symptom scale with a 5-point scoring. The symptom was scored with low to high points. （4）Cognitive function： Quantification measurement was conducted with LOTCA method. The higher points, the better therapeutic effects. RESULTS： （1） Three cases dropped out and one died in the treatment group, 11 cases dropped out and 4 died in the control group. （2）The neurologic impairment points on 7 and 28 days after therapy in the treatment group were lower than those in the control group separately [7 days：（9.73±6.43） points vs. （12.63± 7.87） points, t =2.28, P〈 0.05;28 days：（7.88±4.81） points vs. （9.84±7.03）points, t =2.04, P〈 0.05]. Barthel index on 7 and 28 days after therapy in the treatment group were higher than those in the control group separately [7 days：（54.28±8.38） points vs. （39.76±7.31） points, t =2.206, P 〈 0.05; 28 days： （89.72±7.94） points vs. （67.34±8.63） points, t =2.812, P 〈 0.01]. （4） Patients were allocated into different age groups based on age and evaluated with LOTCA. Results showed that there were no significant differences among different age groups （P 〉 0.05）. （5） Totally 160 patients in the two groups accomplished the Hopkin＇s test, among them, 94 （58.7%） had different mental disorders; Among the patients with mental disorder, depression, obsessive-compulsive and anxiety were found mostly, being 53.8%, 52.5% and 46.2%, respectively. CONCLUSION： （1） Developing stroke rehabilitation unit therapy in the secondary hospital can obviously improve the motor function and activities of daily living of stroke reconvalescents. （2） More than half of the stroke reconvalescents accompany the symptoms of depression, obsessive-compulsive, anxiety and other mental disorders. （3） The cognitive function of stroke reconvalescents is not related to age.展开更多

文摘Double-wall effusion cooling coupled with thermal barrier coating(TBC)is an important way of thermal protection for gas turbine vanes and blades of next-generation aero-engine,and formation of discrete crater holes by TBC spraying is an approved design.To protect both metal and TBC synchronously,a recommended geometry of crater is obtained through a fully automatic multi-objective optimization combined with conjugate heat transfer simulation in this work.The length and width of crater(i.e.,L/D and W/D)were applied as design variables,and the area-averaged overall effectiveness of the metal and TBC surfaces(i.e.,Φ_(av) and τ_(av))were selected as objective functions.The optimization procedure consists of automated geometry and mesh generation,conjugate heat transfer simulation validated by experimental data and Kriging surrogated model.The results showed that the Φ_(av) and τ_(av) are successfully increased respectively by 9.1%and 6.0%through optimization.Appropriate enlargement of the width and length of the crater can significantly improve the film coverage effect,since that the beneficial anti-CRVP is enhanced and the harmful CRVP is weakened.

文摘The application of ecosystem services(ES)theories in land consolidation is a confusing issue that has long plagued scholars and government officials.As the upgraded version of traditional land consolidation,comprehensive land consolidation(CLC)emphasizes ecological benefits,but it does not achieve the expected effect during the pilot phase.This study first proposed a theoretical analysis framework based on ES knowledge to answer the three key questions of why,where,and how to implement CLC better.Taking mountainous counties as the study area,we found that ES trade-offs/synergies,bundles,and drivers were significantly affected by scale effects.ES knowledge can play a crucial role in designing multi-scale CLC strategies regarding the objective,zoning,intensity,and mode.Specifically,mitigating the significant trade-offs between recreational opportunities,food production,and other ES is the top priority of CLC.Land consolidation zoning based on the ES bundles analysis is more rational and can provide the scientific premise for designing locally adapted CLC measures.Land consolidation can be classified into high-intensity direct intervention and low-intensity indirect intervention modes,based on the major drivers of ES.These findings help narrow the gap between ES and CLC practices.

文摘This study examines the multi-scale spatio-temporal evolution of drought characteristics in Zhejiang Province.We propose a comprehensive index to identify drought days and events by incorporating three widely used monitoring indices:the precipitation anomaly percentage,relative humidity index,and standardized precipitation index.The analysis reveals a significant long-term decreasing trend in the frequency of drought days across Zhejiang Province from 1971 to 2020,with a total of 170 drought events being identified.An Empirical Orthogonal Function(EOF)analysis of precipitation anomalies during these events reveals a dominant province-wide monopole mode,alongside a secondary northsouth inverse dipole,a third tripole,and a fourth southwest-northeast inverse dipole.Furthermore,a composite analysis of the drought events demonstrates a widespread increase in temperature across all stations,with a strong spatial correspondence between the temperature anomalies and their associated frequency.The study identifies 21 extreme drought events,characterized by spatially inconsistent precipitation patterns across the entire province.
文摘Objective:To analyze the effect of perioperative comprehensive nursing intervention on patients undergoing breast surgery in oncology surgery.Methods:A total of 100 patients undergoing breast surgery were selected as the study subjects and divided into a control group and a study group.The control group received routine nursing,while the study group received perioperative comprehensive nursing.The effects were observed.Results:The study group had lower negative emotion scores and complication rates than the control group,and higher range of motion of the affected shoulder joint and quality of life than the control group(P<0.05).Conclusion:Oncology breast surgery is often accompanied by adverse psychological emotions during the perioperative period.To ensure surgical efficacy and postoperative recovery,comprehensive perioperative nursing measures can effectively prevent and develop complications,improve shoulder joint range of motion,and promote recovery.

文摘Cognitive emergency communication net-works can meet the requirements of large capac-ity,high density and low delay in emergency com-munications.This paper analyzes the properties of emergency users in cognitive emergency communi-cation networks,designs a multi-objective optimiza-tion and proposes a novel multi-objective bacterial foraging optimization algorithm based on effective area(MOBFO-EA)to maximize the transmission rate while maximizing the lifecycle of the network.In the algorithm,the effective area is proposed to prevent the algorithm from falling into a local optimum,and the diversity and uniformity of the Pareto-optimal solu-tions distributed in the effective area are used to eval-uate the optimization algorithm.Then,the dynamic preservation is used to enhance the competitiveness of excellent individuals and the uniformity and diversity of the Pareto-optimal solutions in the effective area.Finally,the adaptive step size,adaptive moving direc-tion and inertial weight are used to shorten the search time of bacteria and accelerate the optimization con-vergence.The simulation results show that the pro-posed MOBFO-EA algorithm improves the efficiency of the Pareto-optimal solutions by approximately 55%compared with the MOPSO algorithm and by approx-imately 60%compared with the MOBFO algorithm and has the fastest and smoothest convergence.

文摘A novel coaxial ducted fan structure aircraft is proposed to enable the aircraft near vertical walls at high altitudes.The state space equation of the system can be obtained by correlation deduction and identification of the whole prototype model.Based on the duct test bench experiment and computational fluid dynamics(CFD)simulation analysis,the expressions between the different distances dWE from the rotor center of the prototype to the wall and the thrust,reaction torque,and tilting moment of the system under hovering conditions are obtained.The influence of the wall effect of the prototype is incorporated into the system model to analyze the relationship between distance dWE and the comprehensive controllability of the system.The results show that the system comprehensive controllability vector of other channels changes little with the decrease of the distance dWE,and only the controllability vector of the rolling channel increases significantly.At the same time,the tilting moment also increases significantly,which strengthens the tendency of the prototype to tilt towards the wall.
文摘BACKGROUND In patients with liver failure(LF),the high rate of secondary infections,which are associated with poor prognosis,highlights the clinical significance of understanding the underlying risk factors and implementing targeted intervention programs.AIM To investigate risk factors for secondary infections in patients with LF and evaluate the effectiveness of comprehensive nursing interventions.METHODS This retrospective study included 64 patients with LF,including 32 with and 32 without secondary infections.A questionnaire was used to collect data on age;laboratory parameters,including total and direct bilirubin,prothrombin time,blood ammonia,and other biochemical parameters;invasive procedures;and complications.Patients with secondary infections received comprehensive nursing intervention in addition to routine nursing care,whereas those without secondary infections received only routine nursing care to compare the effect of nursing intervention on outcomes.RESULTS The infection rate,which was not associated with age or complications,was significantly associated with biochemical parameters and invasive procedures(P<0.05).The infection rate was 61.6%in patients who had undergone invasive procedures and 32.1%in those who had not undergone invasive procedures during the hospital stay.The infection rate was also significantly associated with the type of LF(P<0.05),with the lowest rate observed in patients with acute LF and the highest rate observed in those with subacute LF.The nursing satisfaction rate was 58.3%in the uninfected group and 91.7%in the infected group,indicating significantly higher satisfaction in the infected group(P<0.05).CONCLUSION In patients with LF,the rate of secondary infections was high and associated with biochemical parameters and type of LF.Comprehensive nursing intervention can improve patient satisfaction.
文摘BACKGROUND： Acute stroke unit （stroke care unit） is developing in some domestic large-sized hospitals, but most stroke patients need stroke rehabilitation unit therapy, so setting stroke rehabilitation unit in medium-sized comprehensive community hospital （secondary hospital）, where medical facility is relatively insufficient, is a new pathway to satisfy stroke patients. OBJECTIVE： To observe the comprehensive effect of developing stroke rehabilitation unit based on the facility of secondary hospital and its feasibility. DESIGN： Non-randomized concurrent controlled observation SETTING： Department of Neurology, Beijing Longfu Hospital PARTICIPANTS： Totally 264 stroke reconvalescents who suffered stroke for 7 days and received treatment in the Department of Neurology, Beijing Longfu Hospital during June 2003 to June 2005 were involved in the study. All the involved patients were confirmed by CT or MRI. The patients were scored by using Modified Edinbergh-Scandinavia stroke scale （SSS） 〉 16 points. Written informed consents were obtained from all the patients. The patients were assigned into 2 groups according to the willing of patients and their relatives： （1）treatment group, in which, there were 134 patients, 76 males and 58 females, aged 43 to 74 years; cerebral infarction was found in 116 cases and cerebral hemorrhage in 18 cases;（2） control group, in which, there were 130 patients, 66 males and 64 females, aged 45 to 77 years, cerebral infarction was found in 115 cases and cerebral hemorrhage in 15 cases. There were significant differences in baseline data of the patients between two groups. METHODS： A same basic treatment was conducted in the patients of the two groups. （1） Patients in the treatment group admitted to stroke rehabilitation unit and received comprehensive rehabilitation treatment. The rehabilitation flow-sheet： randomization-letting the patients of treatment group go into the unit-making comprehensive assessment in the initial stage-making therapy plan-talking with patients and their other family members-general rehabilitation-making metaphase assessment-adjusting therapy plan-making final assessment-letting the patients discharge and doing follow-up visits. （2） The patients in the control group admitted to common wards, and they were encouraged to do activities by themselves in the early stage, but did not receive rehabilitation training under the instructions from professional physicians. MAIN OUTCOME MEASURES： The following assessments were conducted on admission and 7 and 28 days after admission： （1） Severity of stroke and motor function： scored as 0 to 45 points by SSS, the higher points, the severer damage. （2）Activities of daily living： Evaluated by Barthel index, 110 points in total, 110 points meant normal, 0 point meant extremely poor. （3）Mental status： evaluated by Hopkin＇s symptom scale with a 5-point scoring. The symptom was scored with low to high points. （4）Cognitive function： Quantification measurement was conducted with LOTCA method. The higher points, the better therapeutic effects. RESULTS： （1） Three cases dropped out and one died in the treatment group, 11 cases dropped out and 4 died in the control group. （2）The neurologic impairment points on 7 and 28 days after therapy in the treatment group were lower than those in the control group separately [7 days：（9.73±6.43） points vs. （12.63± 7.87） points, t =2.28, P〈 0.05;28 days：（7.88±4.81） points vs. （9.84±7.03）points, t =2.04, P〈 0.05]. Barthel index on 7 and 28 days after therapy in the treatment group were higher than those in the control group separately [7 days：（54.28±8.38） points vs. （39.76±7.31） points, t =2.206, P 〈 0.05; 28 days： （89.72±7.94） points vs. （67.34±8.63） points, t =2.812, P 〈 0.01]. （4） Patients were allocated into different age groups based on age and evaluated with LOTCA. Results showed that there were no significant differences among different age groups （P 〉 0.05）. （5） Totally 160 patients in the two groups accomplished the Hopkin＇s test, among them, 94 （58.7%） had different mental disorders; Among the patients with mental disorder, depression, obsessive-compulsive and anxiety were found mostly, being 53.8%, 52.5% and 46.2%, respectively. CONCLUSION： （1） Developing stroke rehabilitation unit therapy in the secondary hospital can obviously improve the motor function and activities of daily living of stroke reconvalescents. （2） More than half of the stroke reconvalescents accompany the symptoms of depression, obsessive-compulsive, anxiety and other mental disorders. （3） The cognitive function of stroke reconvalescents is not related to age.
