The advent of the Internet of Things or IoT has shed some light on the interoperability issue of these hodgepodges. The proposed framework thus rests on these IoT to achieve such objectives without having to reinvent the wheel or resort to any complex cost-ridden devices and software to operate.

文摘Promoting the deep integration of advanced manufacturing and producer services is not only a key path for metropolitan to climb the global value chain,but also an important new driving force for optimizing urban spatial structure.Based on the two dimen-sions of industrial linkage and spatial co-agglomeration from the perspective of industrial integration,taking Beijing,China as a case,using industrial input-output data,micro-enterprise spatial data,and methods such as industrial linkage model,standard deviation el-lipse,and spatial similarity coefficient,this study explores the coupling relationship between industrial linkage and spatial co-agglomer-ation of advanced manufacturing and producer services from 2007 to 2020.The results demonstrate that:1)the industrial linkage between advanced manufacturing and producer services in Beijing has an upward trend,in which the business services have the most significant improvement,in which the business services have the most improvement while the technology services have the most de-crease,but in general,the industrial linkage between the two industries shows a low level.2)Producer services were more spatially clustered than advanced manufacturing,and the degree of spatial co-agglomeration of the two also showed an increasing trend,with strong regional and industrial heterogeneity characteristics,among which the pairing industry involving commerce services and techno-logy services had a more obvious improvement.3)The coupling analysis found that the spatial dependence between advanced manufac-turing and producer services decreased,showing a weak positive correlation and a decreasing trend between industrial linkage and spa-tial co-agglomeration;the heterogeneity among subdivision pairs is prominent,and the strong correlation between industries does not mean that there is an inevitable spatial co-agglomeration.4)Based on the differences in coupling relationships and influence mechan-isms,four coupling modes are identified:H-H type,H-L type,L-L type,and L-H type.Finally,this study proposes three policy implica-tions for the integration of advanced manufacturing and producer services in metropolitan areas.

文摘Objectives:College students face increasing mental health challenges.Although Acceptance and CommitmentTherapy(ACT)is effective,the efficacy of Internet-based ACT(iACT)needs further exploration.Methods:This study examines the efficacy of iACT on college students’mental health through a randomized controlled trial.We recruited 90 college students(19.16±1.02 years old)and randomly divided them into the iACT group,face-to-face ACT group,and control group.The effects of the interventions were evaluated using the comprehensive assessment of ACT processes(CompACT)and the Depression Anxiety Stress Scales(DASS-21).Results:Two-factor repeated measures ANOVA revealed a significant time main effect of iACT.Face-to-face ACT and iACT effectively improved college students’psychological flexibility[F(2,83)=18.78,p<0.001,η^(2)=0.18]and alleviated their negative emotions[F(2,82)=41.17,p<0.001,η^(2)=0.36].Face-to-face ACT exhibited sustained effects on improving participants’psychological flexibility and alleviating their negative emotions(p<0.001),while iACT showed no sustained effect on improving participants’psychological flexibility(p>0.05).Conclusion:While iACT and face-to-face ACT are effective shortterm interventions,face-to-face ACT demonstrates superior sustainability.Integrating guided sessions into iACT may enhance long-term outcomes.These findings advocate for blended interventions to address college students’mental health needs,particularly in resource-limited settings.
文摘Existing Internet of Things(IoT)systems that rely on Amazon Web Services(AWS)often encounter inefficiencies in data retrieval and high operational costs,especially when using DynamoDB for large-scale sensor data.These limitations hinder the scalability and responsiveness of applications such as remote energy monitoring systems.This research focuses on designing and developing an Arduino-based IoT system aimed at optimizing data transmission costs by concentrating on these services.The proposed method employs AWS Lambda functions with Amazon Relational Database Service(RDS)to facilitate the transmission of data collected from temperature and humidity sensors to the RDS database.In contrast,the conventional method utilizes AmazonDynamoDB for storing the same sensor data.Data were collected from 01 April 2022,to 26 August 2022,in Tokyo,Japan,focusing on temperature and relative humiditywitha resolutionof oneminute.The efficiency of the twomethods—conventional andproposed—was assessed in terms of both time and cost metrics,with a particular focus on data retrieval.The conventional method exhibited linear time complexity,leading to longer data retrieval times as the dataset grew,mainly due to DynamoDB’s pagination requirements and the parsing of payload data during the reading process.In contrast,the proposed method significantly reduced retrieval times for larger datasets by parsing payload data before writing it to the RDS database.Cost analysis revealed a savings of$1.56 per month with the adoption of the proposed approach for a 20-gigabyte database.
文摘With the intensifying aging population,rural elderly care services are facing challenges such as uneven medical resources and inadequate facilities.Taking Qinhuangdao City as an example,this paper explores ways to improve rural elderly care services through the construction of a remote medical service network.This paper analyzes the current status of rural elderly care services in Qinhuangdao City,pointing out that issues such as the uneven distribution of medical resources between urban and rural areas,poor accessibility,and low service quality urgently need to be addressed.The necessity of accelerating the construction of a remote medical network is proposed,including reducing medical costs,optimizing resource allocation,and disease prevention.Specific measures cover aspects such as policy support,integration of medical and elderly care services,talent cultivation,and technology promotion.At the same time,the potential challenges and risks faced by the remote medical service network in improving rural elderly care services are evaluated,and corresponding countermeasures and suggestions are proposed.Research shows that remote medical care can effectively improve the quality of rural elderly care services and help achieve proper medical care for the elderly.

文摘Cultural ecosystem services(CES),which encompass recreational and aesthetic values,contribute to human wellbeing and yet are often underrepresented in forest management planning due to challenges in quantifying these services.This study introduces the Recreational and Aesthetic Values of Forested Landscapes(RAFL)index,a novel framework combining six measurable recreational and aesthetic components:Stewardship,Naturalness,Complexity,Visual Scale,Historicity,and Ephemera.The RAFL index was integrated into a Linear Programming(LP)Resource Capability Model(RCM)to assess trade-offs between CES and other ecosystem services,including timber production,wildfire resistance,and biodiversity.The approach was applied in a case study in Northern Portugal,comparing two forest management scenarios:Business as Usual(BAU),dominated by eucalyptus plantations,and an Alternative Scenario(ALT),focused on the conversion to native species:cork oak,chestnut,and pedunculate oak.Results revealed that the ALT scenario consistently achieved higher RAFL values,reflecting its potential to enhance CES,while also supporting higher biodiversity and wildfire resilience compared to the BAU scenario.Results highlighted further that management may maintain steady timber production and wildfire regulatory services while addressing concerns with CES.This study provides a replicable methodology for quantifying CES and integrating them into forest management frameworks,offering actionable insights for decision-makers.The findings highlight the effectiveness of the approach in designing landscape mosaics that provide CES while addressing the need to supply provisioning and regulatory ecosystem services.
文摘In the 21st century world,people mostly behave with business mentality without considering moral obligations in society.In this behavioral change,the service market,particularly the medical care service market,has appeared to be vulnerable.Because of supplying medical care services,the doctor or hospital receives capitation payments,fees-for-services,risk pool settlements,incentive payments or other fees.However,today it is probably the most criticized profession in world economy country-wise such as Bangladesh.Sometimes doctors here are blamed for requiring unnecessary tests of patients for doctors’own monetary gains.In some cases,doctors’efforts are assumed to relate to pharmaceutical products promotion by writing lengthy prescriptions.Some groups claim that today doctors spend less time on each patient.All these interactions justify claiming that a patient works for a doctor when the patient visits a doctor for medical care services.Here the existence of“asymmetric information”dominates the medical care market where doctor takes advantages in multiple facets.It causes market inefficiency that creates negative economic externalities-deadweight loss.Improving medical education with special emphasis on ethical aspects and soft skills in communication is considered important in order to reduce the magnitudes of today’s dilemma in the medical care service market.Also,strict enforcements of medical care provisions and ethical code of conduct among all health works can be instrumental.Finally,the answer to the question“Are medical care services becoming money-making machines under physicians’headship in the 21st century business-driven world?”depends on who are asked.But the reflections of today’s medical care market in economy of Bangladesh are no deniable,which deserves to be studied further curtailing the magnitudes of the problem.
