    近年来,气候智慧型林业(CSF)已成为可持续森林管理的创新方法,旨在增强森林复原力,并平衡面临气候相关威胁的生态系统服务的提供。这项研究首次引入了一种新的综合气候智能指数(ICSF)来评估CSF。方法包括以下步骤:(i)选择和评估CSF指标;(ii)这些指标的权重;(iii)在两个不同时期对地中海森林的CSF进行评估,特别是2005年和2015年。从系统的文献综述中选取了8个指标。层次分析法用于将通过CSF专家利益相关者网络的在线问卷获得的偏好转化为权重,在指标和标准级别(即,适应,缓解,和社会层面)。结果表明,“树种组成”指标,“森林破坏”,和“再生”对脑脊液评估至关重要。2005年和2015年之间的CSF值的比较显示,CSF评级略有增加。ICSF作为CSF的综合指数,涵盖了该概念的所有方面,即适应,缓解,和社会层面(包括生产)。国家规模的分析概述了涉及地中海森林应对气候变化的森林管理的动态。该研究为CSF评估提供了一种切实可行的方法,代表支持森林管理者减轻气候变化负面影响的合适工具。
    In recent years, Climate-Smart Forestry (CSF) has emerged as an innovative approach to sustainable forest management, aiming to enhance forest resilience and to balance the provision of ecosystem services facing climate-related threats. This study introduces for the first time a new composite climate-smart index (ICSF) to assess CSF. The methodological approach comprises the following steps: (i) the selection and evaluation of CSF indicators; (ii) the weighting of these indicators; and (iii) the assessment of CSF for Mediterranean forests in two distinct periods, specifically 2005 and 2015. Eight indicators were selected from a systematic literature review. The Analytic Hierarchy Process was applied to translate the preferences obtained through an online questionnaire from a network of CSF-expert stakeholders into weights, at both indicators and criteria levels (i.e., adaptation, mitigation, and the social dimension). Results reveals that indicators \"tree species composition\", \"forest damage\", and \"regeneration\" are of crucial importance for CSF assessment. The comparison of the CSF value between the years 2005 and 2015, shows a slight increase in CSF ratings. The ICSF serves as a comprehensive index of CSF covering all aspects of that concept, i.e. adaptation, mitigation, and the social dimension (including production). The national-scale analysis provides an overview of the dynamics that involve forest management of Mediterranean forests against climate change. The study offers a practicable method for CSF evaluation with its allover set of indicators, representing a suitable tool for supporting forest managers to mitigate the negative impacts of climate change.

    纵观世界各国的煤炭开采历史,留下了大面积的采空区,可能发生大面积采空区的突然塌陷和地表沉降,特别是采矿周期长的矿区。辽源矿区北部新区经历了近半个世纪的采矿活动,伴随着灾难的逐渐积累,近年来经常发生。为了评估研究区采空区的稳定性,提出了一种混合决策多因素综合评价方法。利用地球物理勘探技术(地震勘探和瞬变电磁法)和地质钻探勘探确定了地下采空区的分布。首先,建立了基于采空区规范的评价指标体系,生态和地质环境,和开采条件;该系统包括14项指标。两种重量计算方法,AHP-EWM,在改进的博弈理论基础上,结合主客观权重确定各指标的综合权重。随后,利用模糊综合评价法对研究区各区块进行稳定性评价,利用MapGIS和ArcGIS完成了北部新区采空区稳定性区划图的绘制。研究区分为三个稳定区,基本稳定和不稳定,根据临界值。这些区域占23.03%,占研究区总面积的36.45%和40.52%,分别。全面的现场调查显示,从不稳定区到稳定区,塌陷坑的大小和数量以及房屋的损毁率都有所下降。这表明划分结果与实际情况相符。分类结果与实际地面灾害情况一致,从而验证了评价方法的合理性和有效性。结果表明,研究区的稳定性总体上处于中等偏下水平。
    Throughout the history of coal mining in all countries of the world, large areas of goaf have been left behind, and sudden collapses and surface subsidence of large areas of goaf may occur, especially for mining areas with long mining cycles. The northern new district of the Liaoyuan mining area has been subjected to nearly half a century of mining activities, accompanied by a gradual accumulation of disasters, which have occurred frequently in recent years. In order to assess the stability of the goaf in the study area, this paper proposes a hybrid decision-making multi-factor integrated evaluation method. The distribution of underground goafs was determined using geophysical exploration techniques (seismic survey and transient electromagnetic method) and geological drilling exploration. First, an evaluation index system was established based on the specifications of the goaf, the ecological and geological environment, and the mining conditions; the system included 14 indicators. Two weight calculation methods, AHP-EWM, were employed to determine the comprehensive weight of each indicator by combining subjective and objective weights on the basis of improved game theory. Subsequently, the fuzzy comprehensive evaluation method was utilised to complete the stability rating of each block in the study area, and MapGIS and ArcGIS were employed to complete the drawing of the stability zoning map of the northern new district goaf. The study area was divided into three zones of stability, basic stability and instability, according to the critical value. These zones accounted for 23.03%, 36.45% and 40.52% of the total area of the study area, respectively. The comprehensive on-site investigation revealed a decrease in the size and number of collapse pits and the rate of damage to the houses from the unstable zone to the stable zone. This indicates that the results of the division are consistent with the actual situation. The classification results are consistent with the actual ground disaster situation, thus verifying the rationality and validity of the evaluation method. The results indicate that the stability of the study area is generally at the lower middle level.

    An ecological revetment is a new type that combines natural vegetation with civil engineering technology to establish functions, such as flood control, drainage, ecology, and landscape. Various types of ecological and other bank protection lead to different bank protection effects. Urban river ecological bank protection can effectively prevent bank collapse and promote mutual infiltration between river water and soil and is important for maintaining the balance of the river ecosystem and enhancing the ecological service function of river bank protection. To scientifically and accurately evaluate the ecological protection of riverbanks, this study screened 16 evaluation indicators based on four aspects: structural stability, ecological functionality, landscape suitability, and socio-economic status. A comprehensive evaluation index system for urban river ecological protection was constructed and an urban river ecological protection evaluation model based on the AHP - TOPSIS method was established. The model was used to evaluate the ecological protection of the rivers in the study area. The results revealed that the evaluation value, 0.830, of the self-embedded retaining wall exhibited the best performance among the current slope protection types. In addition, structural stability is a crucial factor in river ecological revetments, and the evaluation results were consistent with the revetment type selected in actual engineering. Therefore, the evaluation system constructed in this study is reasonable and reliable and has strong generalizability. This study provides theoretical guidance for selecting ecological protection banks for future river management projects and has specific references important for academic research and the development of environmental protection banks.

    目的:急性卟啉症是一种慢性复发性疾病,诊断较晚,异质性的临床表现和潜在的破坏性并发症。这项研究旨在为急性卟啉症的自然病程提供真实世界的证据,患者特征,疾病负担,以及诊断前的医疗保健利用。
    方法:这项观察性研究使用了来自德国法定健康保险的8365867人的匿名索赔数据,历时6年(2015-2020年)。在指标期间(2019-2020年)至少诊断为急性卟啉症的患者根据发作频率分为三组。将这些发现与两个年龄和性别调整的参考组进行比较:普通人群和纤维肌痛患者。计算了所有卟啉症患者和活动性急性卟啉症患者在指示期内的患病率。
    结果:我们发现急性卟啉症的患病率为79.8/1000,12.9/1000是活跃病例。急性卟啉症患者,特别是频繁的攻击,与普通人群相比,显示出较高的合并症负担。在记录诊断的前一年内,急性卟啉症患者需要平均23.0次医师就诊,显著高于普通人群的16.0。此外,33.8%的人在此期间至少住院一次,比例明显高于普通人群(19.3%)。
    结论:这项研究的发现,在引入吉沃西兰之前收集的,作为欧洲第一个被批准的急性卟啉症预防性疗法,强调需要针对急性卟啉症患者的复杂需求制定医疗策略和政策。巨大的医疗保健需求,加重的共病负担,医疗保健系统利用率的提高强调了为这些患者开发全面支持基础设施的紧迫性。此外,这些急性卟啉症真实世界的发现为德国的疾病特征提供了更多的见解.
    OBJECTIVE: Acute porphyria is a chronic recurrent disease with late diagnosis, heterogeneous clinical presentations and potentially devastating complications. The study aimed at providing real-world evidence on the natural course of acute porphyria, patient characteristics, disease burden, and healthcare utilization before diagnosis.
    METHODS: This observational study used anonymized claims data covering 8 365 867 persons from German statutory health insurance, spanning 6 years (2015-2020). Patients with at least one diagnosis of acute porphyria during the index period (2019-2020) were classified into three groups by attack frequency. These findings were compared with two age- and sex-adjusted reference groups: the general population and fibromyalgia patients. Prevalence over the index period was calculated for all porphyria patients and those with active acute porphyria.
    RESULTS: We revealed a prevalence of 79.8 per 1 000 000 for acute porphyria, with 12.9 per 1 000 000 being active cases. Acute porphyria patients, particularly with frequent attacks, demonstrated a higher comorbidity burden compared to the general population. Within the year before the recorded diagnosis, patients with acute porphyria required a median of 23.0 physician visits, significantly higher than the general population\'s 16.0. Additionally, 33.8% were hospitalized at least once during this period, a notably higher proportion than the general population (19.3%).
    CONCLUSIONS: This study\'s findings, collected before the introduction of givosiran, as the first approved preventive therapy for acute porphyria in Europe, highlight the need for healthcare strategies and policies tailored to the complex needs of acute porphyria patients. The significant healthcare demands, heightened comorbidity burden, and increased healthcare system utilization emphasize the urgency of developing a comprehensive support infrastructure for these patients. Also, these acute porphyria real-world findings provide additional insights on disease characteristics in Germany.

    Ensuring food security and sustainable resource management has become a paramount global concern, prompting significant attention to land suitability analysis for enhancing agricultural production. In this study, an AHP-weighted overlay method was employed to delineate rice cultivation suitability in Guilan province, Iran, a central hub for rice production. Sixteen climatic, topographic, and soil variables were integrated, and individual maps were reclassified to align with the specific requisites for rice production. The results revealed three suitability classes: including \'very suitable,\' \'suitable,\' and \'moderately suitable\', covering 91%, 6%, and 3% of the land, respectively. Soil attributes, particularly organic matter, significantly influenced suitability (weight value of 0.745), with topographic and soil factors outweighing climate in assessment. While salinity is generally absent, organic matter deficiency affects 44% of the land. Phosphorus imbalances are prevalent, with potassium toxicity observed in 10%. Microelement deficiencies, especially in iron and zinc, are noted. Additionally, the results indicated that topographic and soil attributes played a more significant role than climate-related factors in assessing land suitability for rice cultivation within the study area. This research provides a comprehensive spatial analysis of all variables in the study region, shedding light on the complexities of land suitability for rice cultivation. These findings contribute to the understanding of agricultural sustainability and resource management strategies in the context of food security.

    地下水是农业用水的主要来源,工业,和干旱地区的家庭。目前,由于人类活动,迫切需要保护地下水。在这项研究中,选择清水河流域作为研究区域。基于DRASTIC模型,通过优化指标和权重,构建DRASTIC-土地利用类型(DRASTICL)模型和层次分析法-DRASTICL(AHP-DRASTICL)模型。并应用这三种模型计算了地下水脆弱性指数(GVI),绘制了地下水脆弱性图(GVM)。Spearman相关系数的验证结果表明,DRASTICL模型与AHP-DRASTICL模型具有较高的相关性,表明优化后的模型更加准确。其中,AHP-DRASTICL模型的相关系数最高(ρ=0.92),这更符合实际情况。研究结果可为清水河流域地下水的保护与利用提供科学指导。对地下水脆弱性研究具有指导意义,特别是干旱和半干旱地区的地下水管理。
    Groundwater is the main source of water for agriculture, industry, and families in arid areas. At present, there is an urgent need to protect groundwater due to human activities. In this study, the Qingshui River Basin was selected as the study area. Based on the DRASTIC model, the DRASTIC-Land use type (DRASTICL) model and the analytic hierarchy process-DRASTICL (AHP-DRASTICL) model were constructed by optimizing the indicators and weights. And the three models were applied to calculate the groundwater vulnerability index (GVI), and the groundwater vulnerability map (GVM) was drawn. The validation results of Spearman correlation coefficient show that the DRASTICL model and the AHP-DRASTICL model have higher correlation, which indicates that the optimized model is more accurate. Among them, the AHP-DRASTICL model has the highest correlation coefficient (ρ = 0.92), which is more in line with the actual situation. The results of this study can provide scientific guidance for the protection and utilization of groundwater in the Qingshui River Basin. And it is of guiding significance for the study of groundwater vulnerability, especially for groundwater management in arid and semi-arid areas.

    背景:去年,世界见证了大型语言模型(LLM)的采用。尽管使用LLM开发的产品有可能解决医疗保健中的可及性和效率问题,缺乏开发医疗保健LLM的可用指南,尤其是医学教育。
    目的:本研究的目的是确定并优先考虑为医学教育开发成功的LLM的推动者。我们进一步评估了这些确定的推动者之间的关系。
    方法:首先对现有文献进行叙述性回顾,以确定LLM开发的关键推动者。我们还收集了LLM用户的意见,以使用层次分析法(AHP)确定这些推动者的相对重要性,这是一种多准则决策方法。Further,总体解释结构模型(TISM)用于分析产品开发人员的观点,并确定这些推动者之间的关系和层次结构.最后,应用于分类(MICMAC)方法的基于交叉影响矩阵的乘法用于确定这些推动者的相对驱动和依赖能力。非概率目的抽样方法用于招募焦点小组。
    结果:AHP证明了LLM最重要的推动因素是可信度,优先级权重为0.37,其次是问责制(0.27642)和公平性(0.10572)。相比之下,可用性,优先级权重为0.04,显示出微不足道的重要性。TISM的结果与AHP的结果一致。专家观点和用户偏好评估之间唯一显著的区别是,产品开发人员指出,成本作为潜在的推动者最不重要。MICMAC分析表明,成本对其他促成因素有很大影响。焦点小组的输入被认为是可靠的,稠度比小于0.1(0.084)。
    结论:这项研究首次确定,优先考虑,并分析有效医学教育LLM的推动者之间的关系。根据这项研究的结果,我们开发了一个可理解的规范框架,名为CUC-FATE(成本,可用性,可信度,公平,问责制,透明度,和可解释性),用于评估医学教育中LLM的推动者。这项研究结果对医疗保健专业人员很有用,健康技术专家,医疗技术监管机构,和政策制定者。
    BACKGROUND: The world has witnessed increased adoption of large language models (LLMs) in the last year. Although the products developed using LLMs have the potential to solve accessibility and efficiency problems in health care, there is a lack of available guidelines for developing LLMs for health care, especially for medical education.
    OBJECTIVE: The aim of this study was to identify and prioritize the enablers for developing successful LLMs for medical education. We further evaluated the relationships among these identified enablers.
    METHODS: A narrative review of the extant literature was first performed to identify the key enablers for LLM development. We additionally gathered the opinions of LLM users to determine the relative importance of these enablers using an analytical hierarchy process (AHP), which is a multicriteria decision-making method. Further, total interpretive structural modeling (TISM) was used to analyze the perspectives of product developers and ascertain the relationships and hierarchy among these enablers. Finally, the cross-impact matrix-based multiplication applied to a classification (MICMAC) approach was used to determine the relative driving and dependence powers of these enablers. A nonprobabilistic purposive sampling approach was used for recruitment of focus groups.
    RESULTS: The AHP demonstrated that the most important enabler for LLMs was credibility, with a priority weight of 0.37, followed by accountability (0.27642) and fairness (0.10572). In contrast, usability, with a priority weight of 0.04, showed negligible importance. The results of TISM concurred with the findings of the AHP. The only striking difference between expert perspectives and user preference evaluation was that the product developers indicated that cost has the least importance as a potential enabler. The MICMAC analysis suggested that cost has a strong influence on other enablers. The inputs of the focus group were found to be reliable, with a consistency ratio less than 0.1 (0.084).
    CONCLUSIONS: This study is the first to identify, prioritize, and analyze the relationships of enablers of effective LLMs for medical education. Based on the results of this study, we developed a comprehendible prescriptive framework, named CUC-FATE (Cost, Usability, Credibility, Fairness, Accountability, Transparency, and Explainability), for evaluating the enablers of LLMs in medical education. The study findings are useful for health care professionals, health technology experts, medical technology regulators, and policy makers.

    在全球范围内,洪水是最具破坏性的自然灾害,对人类的负面影响越来越大。有必要准确检测洪水多发地区。本研究介绍并评估了在洪水敏感性领域与GIS集成的偏好排序组织方法(PROMETEE),并与两种常规的多准则决策分析(MCDA)方法进行了比较:层次分析法(AHP)和与理想解决方案相似的偏好顺序技术(TOPSIS)。希腊的Spercheios河流域,这是一个高度易感的区域,被选为案例研究。这些方法的应用和研究的完成需要创建一个由八个洪水条件因子(海拔,斜坡,NDVI,TWI,地质学,LULC,距离河网,降雨)和洪水清单(564个地点)和非洪水位置进行验证。各因素的权重基于AHP方法。将输出值导入到GIS中,并进行插值以绘制洪水敏感性区。通过曲线下面积(AUC)和准确性的统计指标对模型进行评估,均方根误差(RMSE),和频率比(FR)。PROMETHEE模型被证明是最有效的,AUC=97.21%。统计指标证实了PROMETHEE的优越性,准确率为87.54%,RMSE为0.12。输出图显示,最容易发生洪水的地区是低地地区的耕地,具有低梯度和第四纪地层。非常高的易感区域约占总面积的15.00-19.50%,并具有最大的FR值。在编制洪水风险管理计划时需要考虑敏感性图,并将其用作减轻洪水不利影响的工具。
    On a global scale, flooding is the most devastating natural hazard with an increasingly negative impact on humans. It is necessary to accurately detect flood-prone areas. This research introduces and evaluates the Preference Ranking Organization METHod for Enrichment Evaluation (PROMETHEE) integrated with GIS in the field of flood susceptibility in comparison with two conventional multi-criteria decision analysis (MCDA) methods: analytical hierarchy process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The Spercheios river basin in Greece, which is a highly susceptible area, was selected as a case study. The application of these approaches and the completion of the study requires the creation of a geospatial database consisting of eight flood conditioning factors (elevation, slope, NDVI, TWI, geology, LULC, distance to river network, rainfall) and a flood inventory of flood (564 sites) and non-flood locations for validation. The weighting of the factors is based on the AHP method. The output values were imported into GIS and interpolated to map the flood susceptibility zones. The models were evaluated by area under the curve (AUC) and the statistical metrics of accuracy, root mean squared error (RMSE), and frequency ratio (FR). The PROMETHEE model is proven to be the most efficient with AUC = 97.21%. Statistical metrics confirm the superiority of PROMETHEE with 87.54% accuracy and 0.12 RMSE. The output maps revealed that the regions most prone to flooding are arable land in lowland areas with low gradients and quaternary formations. Very high susceptible zone covers approximately 15.00-19.50% of the total area and have the greatest FR values. The susceptibility maps need to be considered in the preparation of a flood risk management plan and utilized as a tool to mitigate the adverse impacts of floods.
