Wind-eroded sediment, as an environmental transport pathway of toxic elements and pesticids, can result in environmental and human exposure far beyond the agricultural areas where it has been applied. In our research we quantified the pesticide residues moving in the soil near Szeged (Hungary) on the original soil surface of agricultural areas with a portable wind tunnel. Before the experiments, a portion of the sample area was treated with chlorpyrifos and pendimethalin. A control area was also selected. In 2017-2019, a total of 42 wind event experiments were conducted by examining the topsoil samples. During the experiments, moving soil particles were trapped at various heights (5-10 cm, 20-25 cm and 50-55 cm) and the pesticide concentrates by GC-MS were measured. The enrichment ratios (ER) were calculated, and statistical analyzes were also carried out (SPSS). The measurements obtained that the pendimethalin ER is much higher in the rolled fraction (mean: 13.7) than chlorpyrifos (mean: 2.9). Our measurements showed that the enrichment of chlorpyrifos and pendimethalin can be detected in the rolling and suspended soil particles.
风蚀沉积物作为有毒元素和农药的环境运输途径,其对环境和人类的影响可能远远超出其应用的农业地区。在我们的研究中,我们量化了在塞格德(匈牙利)附近的农业地区原始土壤表面的农药残留移动的便携式风洞。实验前,用毒死蜱和戊二甲基灵处理部分样品区域。还选择了一个控制区。2017-2019年,通过对表层土样品的检测,共进行了42次风事件试验。实验过程中,在不同高度(5-10 cm、20-25 cm和50-55 cm)捕获移动土壤颗粒,并采用气相色谱-质谱法测定农药浓缩物。计算富集比(ER),并用SPSS软件进行统计分析。测量结果表明,在轧制馏分中,对二甲甲烷的ER(平均值:13.7)远高于毒死蜱(平均值:2.9)。我们的测量表明,在滚动和悬浮的土壤颗粒中可以检测到毒死蜱和二甲甲烷的富集。

The present study addresses, for the first time, the problem of spatio-temporal reconstruction of geomorphic processes using tree-rings in the Sâmbăta Valley (Romanian Carpathians). The dendrogeomorphic analysis was conducted in two different sites, one affected by snow avalanches and the other by rockfall. A total number of 130 Picea Abies were sampled in the two sites. The results yield 13 major snow avalanches between 1950 and 2020 and a return period of 3.3 years. The winters with the highest activity index were 1988, 1997 and 2012. The rockfall reconstruction highlights several years of intense activity: 1952, 1955, 2003 and 2012. Thus, the results of the present study provide evidence of active geomorphic processes in the studied area, indicating that tourists are highly exposed to geomorphic hazards, as both sites interfere with popular hiking trails. (Because Sâmbăta Valley is one of the most intensely frequented by tourists in the Făgăraș Mountains, it is a need for warning signs to be installed on the exposed trails.
本研究首次在罗马尼亚喀尔巴阡山脉的姆布塔山谷利用树木年轮对地貌过程进行时空重建。在两个不同的地点进行了树木地貌分析,一个受雪崩影响,另一个受岩崩影响。在两个地点共采集云杉130株。结果显示,1950年至2020年期间发生了13次大雪崩,重现期为3.3年。活度指数最高的冬季为1988年、1997年和2012年。岩崩重建突出了这几年的剧烈活动:1952年、1955年、2003年和2012年。因此,本研究的结果为研究区域内活跃的地貌过程提供了证据,表明游客高度暴露于地貌危害中,因为这两个地点都干扰了受欢迎的远足路线。(因为姆布塔山谷是富尔格鲁拉斯山脉中游客最频繁光顾的地方之一,所以有必要在裸露的小径上安装警告标志。

The paper aims to introduce a new way of comparing the efficiency of public transport operations based on publicly available data. It draws on four main sources, the Hungarian Central Statistical Office, public transport provider data, GTFS and OSM map layers. Methodologically, it combines the use of the GTFS format and corresponding static timetable component files, Thiessen polygons and empirical selection of relative indicators. As places of research, three comparable Hungarian cities have been selected by their population size; Pécs, Szeged and Miskolc. The comparison consists of 8 quantitative indicators that cover six major geographical aspects of transport operation (accessibility in terms of proximity, capacity, connectivity, density, frequency and velocity of vehicles). The analysis does not consider the mode of public transport, thus opening up the possibility of an independent comparison of efficiency regardless of various infrastructure characteristics. The results show that Miskolc and Pécs achieved the best values in four indicators. On the contrary, the city of Szeged, despite its diverse structure of transport modes, does not have an advantage in any aspect. The relatively loosely anchored methodology leaves room for an extension to include economic, environmental, and other specific factors.
本文旨在介绍一种基于公开数据比较公共交通运营效率的新方法。它利用了四个主要来源:匈牙利中央统计局、公共交通提供商数据、GTFS和OSM地图层。在方法上,结合使用GTFS格式和相应的静态时间表组件文件、泰森多边形和相关指标的经验选择。作为研究地点,根据人口规模选择了三个可比的匈牙利城市;psamacs, seeged和Miskolc。比较包括8个量化指标,涵盖交通运营的6个主要地理方面(接近性、容量、连通性、密度、车辆频率和速度方面的可达性)。该分析没有考虑公共交通的方式,从而开辟了独立比较效率的可能性,而不考虑各种基础设施的特点。结果表明,Miskolc和psamuys在4项指标中均达到最佳值。相反,塞格德市尽管交通方式结构多样,但在任何方面都没有优势。相对松散的固定方法为包括经济、环境和其他特定因素的扩展留下了空间。

Due to extreme weather, occasionally Hungary's main rivers and lakes grow an ice cover causing severe damage to infrastructure and increased flood hazard. During cold periods in 2017 and 2022, a dangerous layer of ice developed on the main rivers in the country. Since river ice is rare in this region, no permanent ice monitoring system is in operation. Due to their all weather capabilities, active remote sensing instruments provide a good opportunity to monitor ice coverage. ESA's Sentinel-1 radar satellites acquire data with a relatively high spatial and temporal resolution. A method was developed to provide ice coverage information at a regular interval; depending on the satellite revisit, at least once every 5 days, but often also on a daily basis. In 2017, maps were created for sections along the Danube and in 2022 for another section of the Tisza river. The ice coverage was calculated with a spatial resolution of 10 metre and visualised with a spatial density of 100 metre along the rivers. The mapping procedure provides visual information to give a fast overview of the spatial extent of ice coverage and quantitative , tabular information for operational activities to mitigate the damage due to ice packs and ice jams.
由于极端天气,匈牙利的主要河流和湖泊偶尔会结冰,对基础设施造成严重破坏,并增加洪水的危险。在2017年和2022年的寒冷时期,该国主要河流上形成了一层危险的冰层。由于该地区很少有河冰,因此没有永久性的冰监测系统。由于具有全天候能力,主动遥感仪器为监测冰层覆盖提供了很好的机会。欧空局的哨兵-1雷达卫星以相对较高的空间和时间分辨率获取数据。开发了一种定期提供冰覆盖信息的方法;视卫星情况而定,至少每5天重访一次,但也经常是每天一次。2017年绘制了多瑙河沿岸的地图,2022年绘制了蒂萨河的另一段地图。冰覆盖的空间分辨率为10米,沿河流的空间密度为100米。测绘过程提供了可视化信息,可以快速了解冰覆盖的空间范围,并提供了量化的表格信息,用于减轻冰袋和冰塞造成的损害的业务活动。

Urban air (T a) and surface (T s) temperature patterns depend mainly on the surface cover conditions. WUDAPT methodology was used to create the local climate zone (LCZ) map of Szeged (Hungary) providing detailed information about the structure of the urban area. The seasonal and monthly variations of simultaneous measurements of T a (urban network) and T s (MODIS) in different LCZs were analysed for a four-year period. The results show that the largest differences between T s and T a values occur in late spring and summer. During the day, the monthly mean T s was much higher than the mean T a , while at night, the T a exceeded the T s in all LCZs. Linear statistical relationship was also analysed, which concluded that diurnal and nocturnal T a and T s are strongly correlated in all LCZs in Szeged.
城市空气(T a)和地表(T s)温度模式主要取决于地表覆盖条件。WUDAPT方法用于创建塞格德(匈牙利)的当地气候带(LCZ)地图,提供有关城市区域结构的详细信息。分析了4年时间内不同城市中心区同时测量的T - a(城市网络)和T - s (MODIS)的季节和月变化。结果表明,T s和T a值的最大差异出现在春末和夏季。白天的月平均温度远高于平均温度,而夜间的月平均温度均高于平均值。分析了线性统计关系,结论是白天和夜间的T和T s在塞格德所有lcz中都有很强的相关性。

The juxtaposition of natural levees results in alluvial ridges with a unique fluvial record. Our aims were to (1) identify the alluvial ridges of the Upper Tisza (Hungary); (2) determine their morphological characteristics; and (3) reconstruct the Late Quaternary fluvial history of the region. The oldest paleo-meander was abandoned ca. 29 ka ago; referring to early avulsion of the Tisza. Five alluvial ridges were identified with intensive fluvial activity at ca. 12-13 ka, 7.7-8.6 ka, 6.1-6.6 ka, 4.8 and 2.9 ka ago. Moderate fluvial activity was indicated by early Atlantic and Subboreal paleosols. The sedimentation rate in the paleo-channels (0.3-0.5 mm/y) and on the alluvial ridges (0.3-0.5 mm/y) was slow, influenced by the reactivation of a paleo-channel.
天然堤坝的并置形成了具有独特河流记录的冲积脊。我们的目标是(1)确定上Tisza(匈牙利)的冲积脊;(2)确定其形态特征;(3)重建该区晚第四纪河流史。最古老的古蜿蜒河大约在29万年前被遗弃;指的是Tisza早期的撕裂。5个冲积脊在约12 ~ 13 ka、7.7 ~ 8.6 ka、6.1 ~ 6.6 ka、4.8和2.9 ka前具有强烈的河流活动。早期大西洋和亚北纬古土壤显示出中度河流活动。受古河道恢复作用的影响,古河道沉积速率(0.3 ~ 0.5 mm/y)和冲积脊沉积速率(0.3 ~ 0.5 mm/y)较慢。

Levees are earth structures constructed along alluvial rivers and are considered to be one of the essential components of flood risk and natural hazard reduction. The preservation of their condition would require orderly monitoring. In Hungary, an over 4200 km long levee system was constructed from the 19th century on. Since then, many natural and anthropogenic processes, such as compaction, erosion, subsidence etc., could contribute to the slow but steady deformation of these structures. In the meantime , due to the lack of documentation, their structure and internal composition are still unclear in many sections. The present study uses different geophysical techniques to validate their efficiency in detecting the structure, composition and potential defects along a 3.6 km levee section of the Lower Tisza River, affected significantly by seepage and piping phenomena during floods. Measurements were made using Ground Penetrating Radar (GPR), Electrical Resistivity Tomography (ERT) and drillings. Information obtained by the different techniques was cross-checked and combined. This way, the potential of the applied survey strategy could be demonstrated, and the selected levee section could be assessed in terms of its structure and composition. Consequently, the major reasons for frequently occurring adverse flood phenomena at the site could be revealed. The survey approach outlined in the present paper can be applied extensively along lowland levee systems in the region and elsewhere.
堤防是沿冲积河流建造的土质结构,被认为是减少洪水风险和自然灾害的重要组成部分之一。维持他们的状况需要有序的监测。在匈牙利,从19世纪开始建造了一个超过4200公里长的堤坝系统。从那时起,许多自然和人为的过程,如压实、侵蚀、沉降等,都可能导致这些结构缓慢而稳定的变形。同时,由于文献资料的缺乏,许多章节的结构和内部构成仍不清楚。本研究使用不同的地球物理技术来验证它们在探测下Tisza河3.6公里防洪堤段的结构、组成和潜在缺陷方面的有效性,该防洪堤段在洪水期间受到渗漏和管道现象的严重影响。利用探地雷达(GPR)、电阻率层析成像(ERT)和钻井进行测量。通过不同技术获得的信息被交叉核对和组合。通过这种方式,可以展示应用的调查策略的潜力,并可以根据其结构和组成评估选定的堤防部分。从而揭示了该地区频繁发生逆水现象的主要原因。本文概述的调查方法可以广泛应用于该地区和其他地方的低地堤防系统。

In the past decades, the expansion policy of hard discounters is receiving increasing scientific attention. One of the main reasons of their success is location choices, which needs geographical thinking and knowledge of socio-economic environment. Although it has key importance to gain high purchase power territories in this competition, each company have to implement their own geo-strategy. While discount stores are operating in the town, national franchise small stores have an extensive network in the rural area. This paper is a case study which deals with competition of hard discounters and Coop in Northern Hungary.
在过去的几十年里,硬折扣店的扩张政策正受到越来越多的科学关注。企业成功的主要原因之一是区位选择,区位选择需要地理思维和社会经济环境知识。尽管在这场竞争中获得高购买力地区至关重要,但每家公司都必须实施自己的地缘战略。虽然折扣商店在城镇经营,但全国特许经营的小商店在农村地区拥有广泛的网络。本文以匈牙利北部地区的硬折扣店与合作社的竞争为例进行了研究。

Across the globe marine coasts are experiencing an outstripping growth of the population and economic activity, a phenomenon known as coastalization. Most global cities and industry clusters are located in coastal regions acting as economic growth nodes for their respective countries. This divergence is equally true for national innovation systems, gravitating towards highly urbanized coastal areas. The study is designed to evaluate the spatial stratification of the knowledge production between the coastal regions located in different marine basins - Azov-Black, Caspian, Baltic, Arctic, and Pacific. In order to level-out the national differences of the innovation policy and institutional architecture, the research is held in a single country - the Russian Federation. Our research hypothesis suggests that the knowledge production domain of the innovation activity is influenced by urbanization and coastalization, i.e. the proximity to the core city and the coast. We also expect that the coastalization factor would be reflected in intensified involvement of coastal municipalities in knowledge production networks. The study is based on processing the ROSRID database of 66,647 research projects implemented in 2017-2019 and geocoded using the Yandex.Maps API. The research has shown that the urbanization factor has the strongest influence in configuration of R&D networks - the core centers of knowledge production are the largest cities in marine basins that give further impetus to the involvement of neighboring municipalities. Nearly 70% of municipalities across marine basins have limited or no involvement in the knowledge production, except the Baltic and Azov-Black Sea basins that feature the strongest performance. Overall, the proximity to the coast of non-freezing seas has a positive correlation with the number of R&Ds executed and funded. Considering the research topics, the share of marine-related research is typically funded by coastal regions, whereas the executed R&Ds cover a broad variety of topics. Research results enrich the notion of geography of innovation and advance our understanding of the spatial factors in knowledge distribution within the national innovation system.
全球沿海地区正在经历人口和经济活动的超高速增长,这种现象被称为海岸化。大多数全球城市和产业集群位于沿海地区,是各自国家的经济增长节点。这种差异同样适用于国家创新体系,它们都倾向于高度城市化的沿海地区。该研究旨在评估位于不同海盆(亚速海-黑海、里海、波罗的海、北极和太平洋)的沿海地区之间知识生产的空间分层。为了消除创新政策和制度架构的国家差异,本研究在一个国家-俄罗斯联邦进行。我们的研究假设表明,创新活动的知识生产领域受到城市化和沿海化的影响,即靠近核心城市和靠近海岸。我们还期望沿海化因素将反映在沿海城市加强参与知识生产网络。该研究基于对ROSRID数据库中2017-2019年实施的66,647个研究项目的处理,并使用Yandex进行地理编码。地图API。研究表明,城市化因素对研发网络配置的影响最大,知识生产的核心中心是海洋盆地最大的城市,这进一步推动了周边城市的参与。除了波罗的海和亚速海-黑海盆地表现最好外,近70%的海洋盆地城市很少或根本没有参与知识生产。总体而言,靠近非冰冻海洋的海岸与执行和资助的研发数量呈正相关。考虑到研究主题,海洋相关研究的份额通常由沿海地区资助,而执行的研发涵盖了广泛的主题。研究成果丰富了创新地理学的概念,促进了对国家创新体系内知识分布空间因素的认识。

This paper diagnoses the determination of Covid-19 on economic and social aspects in Indonesia. Panel data collected from 34 provinces in Indonesia for the 2020-2023 period supports the quantitative method. Three analyzes (Spearman, Kendall, and Pearson) were used to measuring the relationship and its partial effect. Research findings indicate that Covid-19 cases have a negative impact on labor productivity , migration, domestic violence, and sexual harassment. From other results, per capita spending , well-being, unemployment, and poverty actually increased when there was a surge in Covid-19. For the Spearman rho correlation, with a degree of 1 percent (p < 0.01), there is a significant effect between capita spending on well-being, per capita spending and well-being on migration, and poverty on labor productivity. Tested by Kendall's tau and Pearson, the Covid-19 tragedy positively affected per capita spending, well-being, unemployment, poverty, and mortality, but labor productivity, migration, domestic violence, and sexual harassment were negatively affected by Covid-19. The partial probability level (p < 0.05 and p < 0.01) reveals a significant effect of per capita spending on well-being, migration on per capita spending and well-being, and poverty on labor productivity. Although per capita spending has a significant impact on well-being (5 percent confidence level), there is a slight difference from the Pearson test, where with a tolerance limit of 1 percent, poverty affects sexual harassment significantly. Covid-19 has taught many things, so that humanity does not disappear with conditions that seek peace. Policy makers need to schedule a more inclusive national and regional resilience system.
本文诊断了Covid-19在印度尼西亚经济和社会方面的决定。从印度尼西亚34个省收集的2020-2023年期间的面板数据支持定量方法。三个分析(Spearman, Kendall和Pearson)用于测量关系及其部分效应。研究结果表明,新冠肺炎疫情对劳动生产率、移民、家庭暴力和性骚扰产生了负面影响。从其他结果来看,当Covid-19激增时,人均支出、福祉、失业率和贫困率实际上有所增加。对于Spearman rho相关,在1%的程度上(p < 0.01),人均支出对幸福感、人均支出和幸福感对移民、贫困对劳动生产率之间存在显著影响。通过Kendall的tau和Pearson的测试,2019冠状病毒病的悲剧对人均支出、福祉、失业、贫困和死亡率产生了积极影响,但对劳动生产率、移民、家庭暴力和性骚扰产生了负面影响。在部分概率水平上(p < 0.05和p < 0.01),人均支出对幸福感的影响显著,移民对人均支出和幸福感的影响显著,贫困对劳动生产率的影响显著。尽管人均支出对幸福感有显著影响(5%的置信水平),但与皮尔逊检验略有不同,皮尔逊检验的容忍极限为1%,贫困对性骚扰的影响显著。Covid-19教会了我们很多东西,因此人类不会随着寻求和平的条件而消失。决策者需要制定一个更具包容性的国家和地区抵御能力体系。
