Objective:To analyze the effect of implementing humanized nursing service intervention for severe patients in the intensive care unit(ICU).Methods:A hundred severely ill ICU patients who were treated from January 2021 to December 2022 were selected and grouped into a control group and an observation group.The control group adopted routine nursing services and the observation group adopted humanized nursing services.The nursing outcome of the two groups was analyzed.Results:The nursing risk incidence of the observation group was lower than that of the control group(P<0.05).The scale of comfort and nursing satisfaction in the observation group was higher than those in the control group(P<0.05).Conclusion:The implementation of a humanized care service for ICU patients lowered nursing risk incidences and increased the physical comfort and nursing satisfaction of these patients.

Multi-scale analysis of ecosystem services trade-offs in an ecotone in the Eastern Margin of the Qinghai-Tibetan Plateau

Understanding the trade-offs among ecosystem services(ESs)at multiple scales is a key challenge to effective environmental management.However,the scale effect of ESs trade-offs in the Qinghai-Tibetan Plateau(QTP)has received little attention.This study investigated the scale effects of ESs trade-offs in Bailongjiang Watershed(BLJW),a typical transitional ecotone from the Loess Plateau to the Tibetan Plateau with multiple ESs,intensive human activities and frequent geological disasters in the Eastern Margin of the QTP,China.Four key ESs including food supply(FS),soil conservation(SC),water conservation(WC),and habitat quality(HQ)in BLJW in 1990,2002,and 2016 were mapped to analyze the scale effects at the watershed,county,and township scales.The results indicated varying scale-related temporal and spatial relationships among FS,SC,WC,and HQ.The trade-offs between FS-SC and FS-WC initially increased and then decreased during 1990-2002 and 2002-2016,respectively,while the trade-offs between SC-WC,SC-HQ,HQ-WC,and HQ-FS first decreased and then increased at the same period.The magnitudes of the trade-offs among the four ESs are in the order of watershed scale>township scale>county scale.Among the major land-use types in BLJW,the trade-offs between WC-FS and between HQ-FS in farmland and grassland were higher than those of other land uses.There is a strong trade-off between SC-HQ in forestland and a weak trade-off between SC-WC in farmland and grassland.The trade-offs between the six ESs pairs varied and were scale-dependent mainly due to spatial heterogeneity in the landscape and in human activities.Understanding the ESs trade-offs at the watershed,county,and township scales provides a scientific basis for the formulation of environmental management strategies at appropriate spatial scales.At the BLJW watershed scale,more attention should be paid on farmland and grassland planning and its management,also,forestland should be enlarged if possible.At the county and township scales,land consolidation and planning should be paid more attention to develop ecological agricultural tourism and multi-functional landscapes for strategic spatial planning and integrated watershed management.

Eco-compensation effects of the wetland recovery in Dongting Lake area

Eco-compensation is an environmental economic instrument for internalization of external cost. Returning farmland to lake is one of the important parts of restoring wetland ecosystem function in the Yangtze River Valley of China. Whether the project of lake recovery can be successful depends on the compensation to the farmers who have lost their original benefits and contributed to the wetland ecosystem recovery by returning farmland to lake. Aiming at the wetland recovery of the Dongting Lake, the practical implementation of pro- grams of the lake recovery and flood control in this area has been challenged by the heavy task of population resettlement, so it is an ideal area for case studies to reach the academic objectives proposed as the above. Based on field survey and experimentation, this research evaluated the benefit losses of the resettled farmers and the increased values of ecosystem service functions caused by wetland recovery, and furthermore, the value of eco-compensation for relocated farmers was calculated by considering the combination of the farmers＇ compensation appeal. The value of eco-compensation for relocated farmers in the Dongting Lake area was 6084.5 yuan per household by synthetic analysis of the effects on wetland ecosystem restoration. Moreover, this article took Dongting Lake area as a case to study and explore the basic issues of the eco-compensation by returning farmland to lake, that was who should pay, who should be paid, how much the payment was and what the payment means was, which sought the mechanisms of wetland restoration eco-compensation and prompted the people＇s enthusiasms for ecological restoration.

Fatigue Life Prediction under Service Load Considering Strengthening Effect of Loads below Fatigue Limit

Lightweight design requires an accurate life prediction for structures and components under service loading histories. However, predicted life with the existing methods seems too conservative in some cases, leading to a heavy structure. Because these methods are established on the basis that load cycles would only cause fatigue damage, ignore the strengthening effect of loads. Based on Palmgren-Miner Rule （PMR）, this paper introduces a new method for fatigue life prediction under service loadings by taking into account the strengthening effect of loads below the fatigue limit. In this method, the service loadings are classified into three categories： damaging load, strengthening load and none-effect load, and the process for fatigue life prediction is divided into two stages： stage I and stage II, according to the best strengthening number of cycles. During stage I, fatigue damage is calculated considering both the strengthening and damaging effect of load cycles. While during stage II, only the damaging effect is considered. To validate this method, fatigue lives of automobile half shaft and torsion beam rear axle are calculated based on the new method and traditional methods, such as PMR and Modified Miner Rule （MMR）, and fatigue tests of the two components are conducted under service loading histories. The tests results show that the percentage errors of the predicted life with the new method to mean life of tests for the two components are –3.78% and –1.76% separately, much lesser than that with PMR and MMR. By considering the strengthening effect of loads below the fatigue limit, the new method can significantly improve the accuracy for fatigue life prediction. Thus lightweight design can be fully realized in the design stage.

Driving Forces and Their Effects on Water Conservation Services in Forest Ecosystems in China

Identifying the driving forces that cause changes in forest ecosystem services related to water conservation is essential for the design of interventions that could enhance positive impacts as well as minimizing negative impacts. In this study, we propose an assessment concept framework model for indirect-direct-ecosystem service （IN-DI-ESS） driving forces within this context and method for index construction that considers the selection of a robust and parsimonious variable set. Factor analysis was integrated into two-stage data envelopment analysis （TS-DEA） to determine the driving forces and their effects on water conservation services in forest ecosystems at the provincial scale in China. The results showed the following. 1） Ten indicators with factor scores more than 0.8 were selected as the minimum data set. Four indicators comprising population density, per capita gross domestic product, irrigation efficiency, and per capita food consumption were the indirect driving factors, and six indicators comprising precipitation, farmland into forestry or pasture, forest cover, habitat area, water footprint, and wood extraction were the direct driving forces. 2） Spearman＇s rank correlation test was performed to compare the overall effectiveness in two periods： stage 1 and stage 2. The calculated coefficients were 0.245, 0.136, and 0.579, respectively, whereas the tabulated value was 0.562. This indicates that the driving forces obviously differed in terms of their contribution to the overall effectiveness and they caused changes in water conservation services in different stages. In terms of the variations in different driving force effects in the years 2000 and 2010, the overall, stage 1, and stage 2 variances were 0.020, 0.065, and 0.079 in 2000, respectively, and 0.018, 0.063, and 0.071 in 2010. This also indicates that heterogeneous driving force effects were obvious in the process during the same period. Identifying the driving forces that affect service changes and evaluating their efficiency have significant policy implications for the management of forest ecosystem services. Advanced effectiveness measures for weak regions could be improved in an appropriate manner. In this study, we showed that factor analysis coupled with TS-DEA based on the IN-D1-ESS framework can increase the parsimony of driving force indicators, as well as interpreting the interactions among indirect and direct driving forces with forest ecosystem water conservation services, and reducing the uncertainty related to the internal consistency during data selection.

The Role of Cooking for Hospital Food Service in Cancer Care-Units: Nutrition Is a Supportive Care While Cooking Appears to Be a Prescription

Cancer cachexia and treatment-induced side effects can contribute to deterioration in nutritional status in patients declining the quality of life and survival rates. Culinary practices may provide new strategies to minimize the symptoms. NEODIA (learning to live with a cancer on a day-to-day basis) is an observational program whose objective is to better understand the occurrence of treatment-related side effects as well as culinary and dietary habits in cancer patients followed in the Cancer Unit of the Beauvais City Hospital, France. First study step in 2010 has investigated culinary solutions to improve the quality of life of the patient at home. The present part tries in particular to answer the question if the culinary advising is transposable to the offer of restoration proposed by institutions of care in oncology. We first conducted an investigation on the determinants of quality of life in patients currently treated in a hospital service involving 41 people. In a second step, we are collecting information on the food supply itself, using advising of some patient’s specially prepared to test meals as a translational research expertise. The results of our survey show that patient’s remarks constitute real guidelines to adapt the practices in culinary production and healthy catering management. Based on these results, the consistency of frozen prepared meals has been analyzed regarding their potential to regulate the under nutrition-inducing treatment-related side effects. Conducted by the patient’s panel of the translational research group the study highlights the benefits of agro-food products and margins of progress.

Impact of taxes on the 2030 Agenda for Sustainable Development:Evidence from Organization for Economic Cooperation and Development(OECD)countries

Multiple ecological and socioeconomic problems have occurred worldwide,raising the awareness of sustainability.This study aims to examine the impact of taxes on Sustainable Development Goals(SDGs)in the context of Organization for Economic Co-operation and Development(OECD)countries.This research used effective average tax(EAT),tax on personal income(TPI),tax on corporate profits(TCP),and tax on goods and services(TGS)as the variables of taxes,and employed secondary data from 38 OECD countries covering 2000–2021.The study also used Breusch-Pagan Lagrange Multiplier(LM),Pesaran Scaled LM,Bias-Corrected Scaled LM,and Pesaran Cross-sectional dependence(CSD)tests to analyze the existence of crosssectional dependency.Then,we established the stationarity of variables through second-generation panel unit root tests(Cross-sectional Augmented Dickey-Fuller(CADF)and Cross-sectional Im,Pesaran,and Shin(CIPS)),and confirmed the long-run cointegration of the variables by using secondgeneration panel cointegration test(Westerlund cointegration test).The results showed that EAT,TPI,TCP,and TGS are positively associated with SDGs.However,the change in TPI has a smaller effect on SDGs than the change in EAT or TCP or TGS.The result of panel causality indicated that EAT,TPI,and TGS have a unidirectional causal relationship with SDGs.The study also found that TCP has a bi-directional causal relationship with SDGs.Moreover,the finding indicated that the OECD countries need to focus on tax policies to achieve the 2030 Agenda for Sustainable Development.This study is based on the theory of optimal taxation(TOT),which suggests that tax systems should be designed to maximize social welfare.Finally,we suggests the importance of taking a comprehensive approach for the managers and policy-makers when analyzing the impact of taxes on SDGs.

Customization and Performance of Service-Oriented Manufacturing Information System: The Mediating Effect of Information System Flexibility

The purpose of this paper is to provide empirical evidence for the validity of the relationship between service-oriented manufacturing information system (SMIS) customization and performance from three aspects: data flexibility, process flexibility and system flexibility. We select some questionnaires from the third round of High-performance manufacturing (HPM) data to construct the construct, verify the reliability and validity of the construct, extract principal components, and analyze the mediating effect by using multiple chain linear regression and structural equation model. The results show that SMIS customization has a significant impact on its performance, and this effect works through its flexibility. More specifically, it is the multiple chain mediation effect composed of data flexibility, process flexibility and system flexibility. The importance of SMIS customization and flexibility to the organization is made clear, which helps practitioners understand the internal mechanism that affects SMIS performance, so as to use limited resources to improve system performance.

Capability matchmaking of semantic web services with preconditions and effects

In order to solve the problem that the current matchmaking methods for semantic web service mainly focus on the matchmaking of IO （inputs, outputs） descriptions which may result in one-sidedness, a description-logic-based IOPE （inputs, outputs, preconditions, effects） description and matchmaking method is proposed for semantic web service. The description logic concept is used to annotate service IO and the description logic assertion is employed to describe service PE（preconditions, effects）. TBox subsumption checking is used to measure the subsumption relationship between IO descriptions of service request and advertising; ABox consistency checking is used for checking the logical implication between PE descriptions of service request and advertising. Based upon the logical implication, four kinds of PE matching degrees are proposed to measure and compare the pros and cons of the results of matchmaking. They are the exact, perfect, side-effect and common match. Experiments show that the method has a higher precision rate under the same recall rate compared with the existing method.

Soil conservation assessment via climate change and vegetation growth scenarios in the Nile River basin

Soil conservation by vegetation can mitigate soil erosion hazard and prevent reductions in food productivity.However,previous research applies little consideration to the interaction between vegetation and climate change in the estimation of future soil conservation change.Therefore,based on the Revised Universal Soil Loss Equation(RUSLE),Representative Concentration Pathways(RCPs,specifically RCP4.5 and RCP8.5),and the vegetation index and precipitation datasets,we built a multivariate regression equation that considers changes in vegetation growth under climate change scenarios in the context of soil conservation.Using the Nile River basin as a case study,via our established methods,we modelled and projected the impact of vegetation and climate change on future soil conservation between 2020 and 2100,where three main results were obtained:(1)under the scenarios of RCP4.5 and RCP8.5 from 2020 to 2100,soil conservation in the Nile Basin will first increase and then decrease,with its highest value in the years 2060,at 117.72(t ha^(-1)y^(-1)),and 2070,at 134.39(t ha^(-1)y^(-1)).(2)Soil conservation under RCP4.5 is lower than that under the RCP8.5 scenario,with a maximum difference of 27(t ha^(-1)y^(-1))in 2040 and a minimum difference of 0.2(t ha^(-1)y^(-1))in 2100.(3)The vegetation and climate change models in 2100 had soil conservation values of 110.77(t ha^(-1)y^(-1))under RCP4.5 and 38.70(t ha^(-1)y^(-1))under RCP8.5.In conclusion,although vegetation growth can increase soil conservation in the Nile River basin,the change in precipitation can offset the soil conservation enhanced by vegetation growth.

Effect and satisfaction of outpatient services by precision valuation reservation registration

BACKGROUND Due to improvements in living standards,people are now paying more attention to their health.In China,more patients choose to go to large or well-known hospitals,which leads to constant crowding of outpatient clinics in these hospitals.AIM To establish precision valuation reservation registration aimed at shortening waiting time,improving patient experience and promoting the satisfaction of outpatients and medical staff.METHODS On the basis of the implementation of a conventional appointment system,more reasonable time intervals were set for different doctors by evaluating the actual capacity of each doctor to receive patients,and appointment times were made more accurate through intervention.The change in consultation waiting time of patients was then compared.Correlations between the consultation waiting time of patients and the satisfaction of patients or satisfaction of medical staff were analyzed.RESULTS After precision valuation reservation registration,the average consultation waiting time of patients reduced from 18.47 min to 10.11 min(t=8.90,P<0.001).The satisfaction score of patients increased from 91.33 to 96.27(t=-8.62,P<0.001),and the satisfaction score of medical staff increased from 90.51 to 96.04(t=-10.50,P<0.001).The consultation waiting time of patients was negatively correlated with their satisfaction scores(γ=-0.89,P<0.001).The consultation waiting time of patients was also negatively correlated with medical staff satisfaction scores(γ=-0.96,P<0.001).CONCLUSION Precision valuation reservation registration significantly shortened outpatient waiting times and improve the satisfaction of not only patients but also medical staff.This approach played an important role in improving outpatient services,provided a model that is supported by relevant evidence and could continuously improve the quality of management.Precision valuation reservation registration is worth promoting and applying in the clinic.

Factors Determining Health Expenditure in the Asian and the OECD Countries

It is widely recognized that developed countries have been spending more than developing countries on health care. Objective of the study is to examine determinants of health expenditure and what factors influence it. Fifteen Asian countries and 30 OECD countries were chosen to explore the difference of their health expenditure structures. Model of health expenditure per person was estimated to be dependent on market demand, market supply, and other exogenous factors. A model with country specific and time effects of health expenditure was used and estimated. The study found a negative but insignificant relationship between price and health expenditure and a positive and significant relationship between GDP and health expenditure. Urban population density as proxy of urbanization was found to induce the health expenditure in the OECD. Out-of-pocket payment was also found to induce health expenditure for both the Asian and the OECD countries. A net effect of improvement in the health status or a lower mortality rate and a higher life expectancy caused an increase in the health expenditure among the Asian countries studied but decreased health expenditure in the OECD countries. In terms of income elasticity, it was found to be smaller than one in both groups of the countries. Since the income has changed faster than the other factors, the net effect of changes of all factors over period of time will cause rising in health care expenditure. Finally, the model indicated that both the Asian and OECD countries will continue to have a rising health expenditure per person over a period of time.

Models to Simulate Effective Coverage of Fire Station Based on Real-Time Travel Times

In recent years,frequent fire disasters have led to enormous damage in China.Effective firefighting rescues can minimize the losses caused by fires.During the rescue processes,the travel time of fire trucks can be severely affected by traffic conditions,changing the effective coverage of fire stations.However,it is still challenging to determine the effective coverage of fire stations considering dynamic traffic conditions.This paper addresses this issue by combining the traveling time calculationmodelwith the effective coverage simulationmodel.In addition,it proposes a new index of total effective coverage area(TECA)based on the time-weighted average of the effective coverage area(ECA)to evaluate the urban fire services.It also selects China as the case study to validate the feasibility of the models,a fire station(FS-JX)in Changsha.FS-JX station and its surrounding 9,117 fire risk points are selected as the fire service supply and demand points,respectively.A total of 196 simulation scenarios throughout a consecutiveweek are analyzed.Eventually,1,933,815 sets of valid sample data are obtained.The results showed that the TECA of FS-JX is 3.27 km^(2),which is far below the standard requirement of 7.00 km^(2) due to the traffic conditions.The visualization results showed that three rivers around FS-JX interrupt the continuity of its effective coverage.The proposed method can provide data support to optimize the locations of fire stations by accurately and dynamically determining the effective coverage of fire stations.

The Role of Green Infrastructure in Mitigating the Urban Heat Island Effect

The accelerating urbanization process and intensifying climate change have exacerbated the urban heat island effect, threatening sustainable urban development. This study investigates the role of green infrastructure in mitigating urban heat island effects, its implementation challenges, and applications. Employing a system dynamics approach, the research models the relationships between green infrastructure, urban microclimate, and human well-being. Findings indicate that large, continuous green spaces, such as urban parks and green corridors, are most effective, potentially reducing surrounding temperatures by 1˚C - 4˚C. Green infrastructure also provides multiple ecosystem services, including improved air quality and increased biodiversity. However, its implementation faces challenges such as land resource limitations and financial constraints. To address these issues, the study proposes a performance-based planning method, emphasizing multifunctional design and cross-sectoral collaboration. Through analysis of international and Chinese urban case studies, best practices and lessons learned are summarized. The research demonstrates that successful strategies must be context-specific, integrating local conditions while emphasizing long-term planning and continuous optimization. This study provides a scientific basis for developing effective heat island mitigation strategies and climate adaptation plans, ultimately achieving sustainable urban development and improved living environments.
