Traditional Chinese medicine with its effectiveness should also have stemmed out from such logic system. This article aims to rearticulate the underlying lucid multi-dimensional logic system, which faded in obscurity only because of time-out loss of the mid-right concept. Retracing this past tacit but important concept could uncover a multi-dimensional system over a point relating to all matters while capturing the central core of the matter. The seemingly unmanageable multidimensional logic was strengthened by verification processes which affirmed its further extensions, and made up the language of the people, the concepts of yin-yang(阴阳), and the development of extensions of Ba Gua(八卦) derivatives, which furthered the interpretation of the space-time properties and Chinese medicine.展开更多

A validated self-administered questionnairethat included 13 attitudes and 14 barrier items was used as a tool. The reliabilityof the tool was 0.89 (Cronbach's alpha). In the analysis of attitude scores, responseswere rated on a scale from 0 to 4, with 0 representing 'strongly disagree'and 4 representing 'strongly agree' for supportive attitudes towards organdonation. Participants with a total attitude score of 39 or higher indicated agreementor strong agreement with all items, reflecting a generally supportiveattitude toward organ donation. Lower scores suggested that the respondent wasneutral or disagreed with one or more items, indicating a less supportive attitudetoward organ donation. Knowledge about organ donation was assessed by selfadministeredquestionnaire that included 13 items. Analysis was done using SPSSversion 29. χ2 was used to assess associations between variables.RESULTSMost participants were young (≤ 30 years old, 83.7%), female (79.2%), from World Health Organization Eastern Mediterranean Region countries (69.5%), Muslim (82.4%), students (80.6%), single(83.9%), and from a nursing college (33.1%). The majority had no personal or family history of organ donation(93.2% and 93.9%, respectively). Supportive attitudes toward organ donation were significantly associated withreligion (P = 0.003), working status (P = 0.009), university (P = 0.019), and knowledge (P < 0.001). Additionally,those with a personal or family history of organ donation were significantly more supportive (56.8% vs 33.3%, P =0.004). Lack of awareness was the most reported barrier for organ donation (64.1%) followed by being afraid oforgan donation due to medical procedures required (51.9%).CONCLUSIONThe findings suggest that supportive attitudes toward organ donation are influenced by demographic factors,personal experiences, and knowledge levels. Lack of awareness and fear of medical procedures were the mostreported barriers to organ donation. These results highlight the need for targeted educational programs to increaseawareness and promote positive attitudes toward organ donation.展开更多

文摘Objectives To investigate the barriers and facilitators influencing the sustainable implementation of evidence-based practice(EBP)for Peristomal Irritant Contact Dermatitis(PICD)based on the Consolidated Framework for Implementation Research(CFIR).Methods The sample consisted of 17 nurses from three urology wards at a tertiary hospital in Beijing,China,who had participated in the EBP.Guided by the CFIR,we identified constructs influencing the sustainability of implementation by conducting a directed content analysis of the 17 individual in-depth interviews.By rating,the valence and magnitude of each construct were determined.Results This study identified 19 factors across the five domains of the CFIR.Among these determinants,16 were identified as barriers,while three were recognized as facilitators.Common barriers across different contexts were identified,such as delayed evidence updating,the complexity of intervention components and steps,and incompatibility between the implementation process and clinical practices.In contrast,facilitators of intervention implementation were regular communication and feedback,support and drive from principals and a positive cultural atmosphere.In addition,we identified“regular evidence updating”as an independent construct outside of the CFIR,a finding that will provide key information for updating the CFIR framework.Conclusions Regular evidence updating is crucial for the sustainability of EBP implementation.Researchers should receive consistent feedback from practitioners and adjust or modify the EBP as necessary.Additionally,researchers must consider the compatibility or adaptability of the EBP’s content with clinical practice in formulating it rather than adding additional complexity to the original workflow.

文摘Constructing multi-dimensional hydrogen bond(H-bond)regulated single-molecule systems with multiemission remains a challenge.Herein,we report the design of a new excited-state intramolecular proton transfer(ESIPT)featured chromophore(HBT-DPI)that shows flexible emission tunability via the multidimensional regulation of intra-and intermolecular H-bonds.The feature of switchable intramolecular Hbonds is induced via incorporating several hydrogen bond acceptors and donors into one single HBT-DPI molecule,allowing the“turn on/off”of ESIPT process by forming isomers with distinct intramolecular Hbonds configurations.In response to different external H-bonding environments,the obtained four types of crystal/cocrystals vary in the contents of isomers and the molecular packing modes,which are mainly guided by the intermolecular H-bonds,exhibiting non-emissive features or emissions ranging from green to orange.Utilizing the feature of intermolecular H-bond guided molecular packing,we demonstrate the utility of this fluorescent material for visualizing hydrophobic/hydrophilic areas on large-scale heterogeneous surfaces of modified poly(1,1-difluoroethylene)(PVDF)membranes and quantitatively estimating the surface hydrophobicity,providing a new approach for hydrophobicity/hydrophilicity monitoring and measurement.Overall,this study represents a new design strategy for constructing multi-dimensional hydrogen bond regulated ESIPT-based fluorescent materials that enable multiple emissions and unique applications.
文摘Traffic-induced ground vibrations cause significant problems for residents and nearby structures.Reducing the effect of these vibrations on the neighboring environment is a key challenge,particularly in urban areas.This study presents both numerical and experimental investigations of the performance of mass scatters for screening ground vibrations.A three-dimensional numerical model is validated and extended to conduct a comparative study on the efficiency of three geotechnical methods of isolation.These methods include trench barriers,waveimpeding blocks(WIBs),and mass scatters.The results showed that mass scatters represent an efficient way of scattering ground vibrations,and their efficiency is mainly related to the weights of mass scatters and their natural frequency,which control the dynamic soil response in the frequency domain.Rigid trench barriers are less effective than soft ones,and their efficiency is more pronounced regarding the WIB.Soft barriers with a depth of an order of half of the wavelength can decrease the vibration levels by up to 50%,which is comparable to the performance of enormous mass scatters.The dimensions of WIBs must be chosen according to the wavelength of incident waves and the cutoff frequency of the topsoil layer.Considering the significant wavelength of traffic-induced vibration,the use of trench barriers or WIBs becomes impractical and expensive;therefore,mass scatters appear to be an efficient and practical solution.
文摘Objective:This review examined the co-morbidity of malaria and hypertension in Nigerian adults,with a focus on epidemiological trends,genetic and environmental risk factors,pathophysiological mechanisms,and systemic healthcare barriers.Methods:A qualitative synthesis of peer-reviewed literature,national health surveys,and institutional reports published between 2000 and 2025 was conducted using thematic analysis.While centered on Nigeria,the review incorporated comparative insights from global studies on renin angiotensin aldosterone system polymorphisms,co-infection dynamics,and health service inequalities.Results:The findings indicate overlapping risk factors including renin angiotensin aldosterone system gene polymorphisms,urbanization,and poverty.Angiotensin Ⅱ demonstrates dual functions,contributing both to malaria suppression and to hypertension pathogenesis.Clinical challenges include diagnostic overlap,adverse drug interactions,and disparities in service delivery between rural and urban populations.These challenges particularly affect older adults and highlight systemic gaps in access,workforce distribution,and policy alignment.Conclusion:The dual burden of malaria and hypertension in Nigeria requires integrated disease management strategies that address both communicable and non-communicable disease risks.Urgent priorities include multisectoral policy reforms,expanded rural health investments,and the adoption of precision medicine approaches guided by genetic profiling.The implications extend to clinical practice through co-screening and tailored treatment protocols and to public health policy,where integrated frameworks are essential to reducing inequities and improving long-term outcomes.
文摘Born and raised in Japan,Tatsuya Amano started learning English in the 7th grade.But after finishing his doctorate at the University of Tokyo in 2006,he began traveling to international scientific conferences.To his dismay,he discovered his English was not good enough to allow him to converse with many of the other participants.“I found so many barriers to communicating with other people in English,”recalled Amano,now an associate professor in the School of the Environment at the University of Queensland in Brisbane,Australia.
