"Outlining precision boundaries among areas with different variability standards using magnetic susceptibility and geomorphic surfaces." Engenharia Agrícola 34, no. 4 (August 2014): 695–706. http://dx.doi.org/10.1590/s0100-69162014000400009.
Full textAbstract:
There is an increasing demand for detailed maps that represent in a simplified way the knowledge of the variability of a particular area or region maps. The objective was to outline precision boundaries among areas with different accuracy variability standards using magnetic susceptibility and geomorphic surfaces. The study was conducted in an area of 110 ha, which identified three compartment landscapes based on the geomorphic surfaces model. To determinate pH, organic matter, phosphorus, potassium and magnesium, the total sand and clay, 514 soil samples were collected at depths of 0-0.20 m and 0.60-0.80 m. The sum of base, cationic exchange capacity and base saturation were calculated and the magnetic susceptibility was evaluated in the laboratory using a system based on a balance of analytical precision method. Geomorphic surfaces identification allowed setting specific management areas (locations with maximum homogeneity of soil attributes). The map of spatial variability of magnetic susceptibility can be used to validate the precise boundaries among geomorphic surfaces identified in the field and infer the variability of clay content and soil base saturation.

Purpose – The overall purpose of this paper is to detect spatial, temporal, sectoral, thematic and other patterns or transitions in techno-socio-economic evolution that are likely to co-determine future development and allow the steering of it. The development of a “Global Change Data Base” (GCDB) promises a graphically and geographically oriented tool for the representation of correlations for global long-term data series. Design/methodology/approach – A literature analysis supports the interpretation of such “pattern recognitions”, especially the literature in the areas of economic growth, systems analysis, energy economics, social indicators and quality of life. Preconditions for economic growth are empirically analysed on a sectoral level along with prevailing structural shifts in the use of energy sources. Findings – The main outcome is a distillate of a few formative “paths of development”, according to a synthesis of to-date growth theories. These lines might influence development in future decades and co-determine the degree to which sustainability targets are met. Debates and discussion procedures make use of such findings and outline modes of actions. Practical implications – Developmental university curricula such as “Global Studies”, democratisation endeavours based on analyses of economic performance of (partly) democratic systems or global governance of science could profit from a consensus on global trends patterns, similar to the Intergovernmental Panel on Climate Change endeavour at the United Nations level. Social implications – Such heuristic methods could suitably mediate (in “multicultural” manner) between contradictory paradigms of global economic development that are mainly ideology-driven and hamper global society’s joint action. Originality/value – In short, this is an empirical work on pattern recognition in global evolution using aggregated spatially and temporally enabled data. It refers to the historic example of Kon-Tiki which undertook a surprisingly long journey based on precise knowledge of ocean currents and wind without applying own force.

Full textAbstract:
There are numerous traces around the world that testify on the duration and significance of the Roman Empire. There are many more Roman traces in Serbia, than it could be seen in the field. Many traces have been lost or forgotten forever. Roman Margum is one of them. On the base of outline maps and historical facts, this work aims to revive the Roman era on the site Margum, in an innovative way, by using natural vegetation and installation. The approach to work has a multidisciplinary character. By analyzing the current situation and by using a check list, it was found that partly carried out archaeological excavations were not visible, and that their invisibility was more enhanced with invasive vegetation that occupied the space. The revitalization of the site Margum will not only contribute to the cultural heritage of Serbia, but also to a tourist activation of the space and its surroundings and to raising the attractiveness of the site as well.

Full textAbstract:
The purpose of this article is an attempt to outline the specifics of artistic mapping in contemporary literature through conceptualization to understand the „map” and territory "in the context of geopoietics studios. Philosophical and cultural works, which supplement the theoretical and methodological base of geopoetics, were chosen as the methodological basis for the research. Metaphor „A map is not the territory” (Alfred Korzybski) serves to explain the representation of the world, the description of reality. Artistic expictations of cartography are considered on the material of the works „Voroshilovgrad” by Sergey Zhadan, „The Map and the Territory” by Michel Welbeck, „Certain Judgments about Byzantium” by Velimir Churgus Kazimir. This article analyzes the problem of reality and literature interrelation and the problem of man and landscape relations. It is memory and place through the landscape that allow to connect local, ethnic and global aspects into a single whole. Cultural and civilization projections, map and territory designs are perceived in modern humanities as a manifestation of struggle and mutual overlay of „tree” and „root” cultures. The research of the transcultural communications in the artistic space, allows to define modern aesthetics as the universalistic functions. Local space and limited geo-cultural landscape inspires individual mythology of modern writers. In modern fiction we often observe incorporation of historical facts, fragments of pseudo-documents, description of real landscapes and maps of invented territories into the text.

Remote-sensing methods in monitoring the glacierization of Mount EI‛ brus are used to produce base and dynamic maps, and to obtain quantitative information (dynamic indices) about the rate, intensity, and variations of the process. The monitoring system is divided, according to scope and territory covered, into small-scale for total glacierization and the periglacial zone, medium-scale for separate glaciers, and large-scale (detailed) for part of the glaciers or sectors of the adjoining slopes. The approximate relationship of even scales is 1 : 4. Small-scale monitoring remote-sensing systems are important for making maps showing the complex characteristics of the glaciological system. A series of maps was produced including geographical, those of high-altitude zones, slope and exposure angles, geological, glaciomorphological, climatic (temperature, precipitation, and winds), distribution of direct solar radiation, hydrological (source of streams), seats of avalanches, and landslides. All these data serve as a cartographical basis in monitoring the glacierization of Mount EI‛ brus. They are compiled from remotely sensed and Earth-based data. Current monitoring on a small scale includes observations of the conditions which determine the existence of the glacial system - this includes data on winter snowfall and the period of snow cover. These observations were obtained from meteorological and resource satellites, and from scanner data of medium and high resolution. Also important are observations of changes in the outline of glaciers, times of snowfall and character of the distribution of snow, and its redistribution due to avalanches and snowstorms. High-resolution space photographs, small-scale aerial photographs, and aerovisual observations provide the data for these observations. It has been determined that the area of the glaciers of Mount El‛ brus has been reduced by 1 % in the last 25 years, i.e. the rate of its deglacierization dropped sharply as compared to preceding decades. The role of quantitative information gains importance in the medium-scale level of monitoring. Topographical maps of separate glaciers compiled from aerial photographs or data from ground stereo-photogrammetric surveys constitute the base maps at this level. The main method used in monitoring were large-scale surveys from aircraft, perspective surveys from helicopters, and phototheodolite surveys. Multi-date surveys of the glaciers provide data about the changes in their outlines and height, the character of their relief, their moraines, the amount of snow accumulation and ablation in separate years, the surface rates of ice flow and their fluctuations. The techniques by which quantitative information is obtained about changes in the glaciers are derived from processing the data of multi-date surveys. The organization and techniques of phototheodolite surveys have been improved. A theory evolved for determining the surface-ice movement by stereo-photogrammetric means and the technique for it has also improved; algorithms and programs for machine processing of the data of multi-date surveys (ground and from aircraft) have been produced At this level of monitoring, it has been found that the retreat rate of most glaciers has slowed down and several glaciers are now in equilibrium. Several glaciers became active at the beginning of the 1970s and 1980s; this was accompanied by an increase in their height and forward movement. For example, activation of Kyukyurtlyu Glacier has been recorded (higher surface and increasing flow rate) which has caused the glacier to move forward 100 m. Surveys at an interval of 2 years recorded the beginning of the process of retreat of this glacier. Detailed monitoring is used to detect the mechanism of the dynamic processes and to study it on local representative sectors. On a glacier it may take the form of annual surveys of its tongue, which makes it possible to observe the processes of formation of moraines and glacio-fluvial relief. Studies may also be made of the mechanism of the movement of avalanches and landslides, deducing their quantitative characteristics and appraising the results of avalanches and landslides. Multi-date surveys of sectors of the slopes provide information about processes in the periglacial zone. At this level, regularly repeated ground stereo-photogrammetric surveys are the main means of observation. Glaciological remote-sensing monitoring provides a wealth of data for theoretical development in the field of glaciology. It makes it possible to forecast and produce warnings about hazardous processes and phenomena.

Abstract. In the fall of 2017, an airborne field campaign was conducted from the NASA Armstrong Flight Research Center in Palmdale, California, to advance the remote sensing of aerosols and clouds with multi-angle polarimeters (MAP) and lidars. The Aerosol Characterization from Polarimeter and Lidar (ACEPOL) campaign was jointly sponsored by NASA and the Netherlands Institute for Space Research (SRON). Six instruments were deployed on the ER-2 high-altitude aircraft. Four were MAPs: the Airborne Hyper Angular Rainbow Polarimeter (AirHARP), the Airborne Multiangle SpectroPolarimetric Imager (AirMSPI), the Airborne Spectrometer for Planetary EXploration (SPEX airborne), and the Research Scanning Polarimeter (RSP). The remainder were lidars, including the Cloud Physics Lidar (CPL) and the High Spectral Resolution Lidar 2 (HSRL-2). The southern California base of ACEPOL enabled observation of a wide variety of scene types, including urban, desert, forest, coastal ocean, and agricultural areas, with clear, cloudy, polluted, and pristine atmospheric conditions. Flights were performed in coordination with satellite overpasses and ground-based observations, including the Ground-based Multiangle SpectroPolarimetric Imager (GroundMSPI), sun photometers, and a surface reflectance spectrometer. ACEPOL is a resource for remote sensing communities as they prepare for the next generation of spaceborne MAP and lidar missions. Data are appropriate for algorithm development and testing, instrument intercomparison, and investigations of active and passive instrument data fusion. They are freely available to the public.

Full textAbstract:
The spontaneous pairing of rolled-up vortices in a laminar jet is investigated as a global secondary instability of a time-periodic spatially developing vortex street. The growth of subharmonic perturbations, associated with vortex pairing, is analysed both in terms of modal Floquet instability and in terms of transient growth dynamics. The article has the double objective to outline a toolset for the global analysis of time-periodic flows, and to leverage such an analysis for a fresh view on the vortex pairing phenomenon. Axisymmetric direct numerical simulations (DNS) of jets with single-frequency inflow forcing are performed, in order to identify combinations of the Reynolds and Strouhal numbers for which vortex pairing is naturally observed. The same DNS calculations are then repeated with an added time-delay control term, which artificially suppresses pairing, so as to obtain time-periodic unpaired base flows for linear stability analysis. It is demonstrated that the natural occurrence of vortex pairing in nonlinear DNS coincides with a linear subharmonic Floquet instability of the underlying unpaired vortex street. However, DNS results suggest that the onset of pairing involves much stronger temporal growth of subharmonic perturbations than that predicted by modal Floquet analysis, as well as a spatial distribution of these fast-growing perturbation structures that is inconsistent with the unstable Floquet mode. Singular value decomposition of the phase-shift operator (the operator that maps a given perturbation field to its state one flow period later) is performed for an analysis of optimal transient growth in the vortex street. Non-modal mechanisms near the jet inlet are thus found to provide a fast route towards the limit-cycle regime of established vortex pairing, in good agreement with DNS observations. It is concluded that modal Floquet analysis accurately predicts the parameter regime where sustained vortex pairing occurs, but that the bifurcation scenario under typical conditions is dominated by transient growth phenomena.

Outlier detection is critical in many business applications, as it recognizes unusual behaviours to prevent losses and optimize revenue. For example, illegitimate online transactions can be detected based on its pattern with outlier detection. The performance of existing outlier detection methods is limited by the pattern/behaviour of the dataset; these methods may not perform well without prior knowledge of the dataset. This paper proposes a multi-level outlier detection algorithm (MCOD) that uses multi-level unsupervised learning to cluster the data and discover outliers. The proposed detection method is tested on datasets in different fields with different sizes and dimensions. Experimental analysis has shown that the proposed MCOD algorithm has the ability to improving the outlier detection rate, as compared to the traditional anomaly detection methods. Enterprises and organizations can adopt the proposed MCOD algorithm to ensure a sustainable and efficient detection of frauds/outliers to increase profitability (and/or) to enhance business outcomes.

Social work education accreditation standards have recently shifted from objective-based standards to a competency-based approach. One distinguishing characteristic of a competency-based curriculum is a focus on competence or mastery of a specific set of capabilities. In response to these changes, accredited social work programs are reorganizing curriculum and assessment plans. This article provides background information on competency-based education; curriculum mapping; and direct assessment. Additionally, the article outlines an example of the process of aligning teaching and assessment to program-level competencies with respect to the Council on Social Work Education's Educational Policy and Accreditation Standards. A discussion and tools such as maps and rubrics that can help provide direction and consistency to faculty efforts in teaching and assessing also are included.

It is suggested to use geographical information systems based approach to simplify workflow. The result of investigation is a series of maps divided into 2 groups: estimation of natural resources for renewable energy, and evaluation of limitations caused with socioeconomic policy. These maps help us to outline the most suitable as well as restricted places for perspective power plants.

Purpose This paper aims to address the extant and arguable role of enterprise systems (ES) in relation to management accounting practices (MAPs) through an inclusion relative neglect account of business process management (BPM). This is also extended to draw out an analytical framework to advance our understanding of how BPM mediate ES-MAPs interplay. Design/methodology/approach A cross-sectional case study was adopted as a research strategy with which to collect data about the ES-BPM-MAPs interplay as a unit of analysis. The latter, in the first stage, was examined across (89) mini-case studies operating in the UK context through reports and documentations collected from cases’ websites, vendors and consultants of information systems. Drawn insights from cross-sectional analysis and contributions made by prior studies are blended together to inform the second stage that outlines an analytical framework for ES-BPM-MAPs interplay. Findings Different ES are mobilised to address different orientations of BPMs and being used for different managerial functions and purposes. Different patterns of ES-BPM-MAPs interplay are identified across (89) UK-case studies and the BPM is a fulcrum understanding. These patterns are centred around three key BPM including customer, logistics and control processes and all oriented by a continuum of an organisation intention focus on control, understanding and strategising. Both processes and orientations explain ES development and MAPs evolution processes. Standardisation, integration and intelligence are key characteristics sought through ES mobilisations. By complementary, information provision, analytics and simulation are three sophisticated ways of using MA information facilitated by ES characteristics. Research limitations/implications Dynamic processes of MAPs change over time and are beyond the reach of this study. Such approach requires full access to case studies. BPM is fulcrum understanding of MAPs change and/or stability in relation to ES implementation including other components. Practical implications Findings and analytical framework could be used as a base for establishing the best approach in adopting ES to fully exploit the potential of future ES applications as well as to avoid organisations pitfalls of implementations. Organisations are advised to understand their existing business processes, characteristics of MA information would be achieved first upon which decision of ES components selection and implementation could be outlined. Originality/value The indirect interplay between ES and MAPs through business processes is rarely examined. By the inclusion of BPM and using cross-sectional case studies, this research contributes to the existing shortcomings of ES-MAPs interplay by broadening the picture and proposing an analytical framework. The latter advances our understanding by focusing on attributes of ES-BPM-MAPs upon which informal changes in-the use of MAPs are recognised.

A análise da territorialização da votação nesse novo partido, o Chega, na escala municipal, apresenta um padrão que não se coaduna com o que tem sido a geografia eleitoral em Portugal desde a Revolução Democrática de 1974, sugerindo as correlações com um conjunto alargado de variáveis com uma forte motivação identitária da sua base eleitoral, que aparece associada a alguns elementos de desvantagem social e económica. Simultaneamente, a sociologia dos eleitores do Chega apresenta alguns aspetos surpreendentes em face do que se sabe para a generalidade dos casos europeus.

Problem-based learning (PBL), initiated when learners meet an ill-structured problem, develops skills and subject-matter content needed by students to make the transition from novice to more expert problem solver. However, the construction of problem-based learning units can be a formidable task. After a brief comparison of the characteristics of well-structured and ill-structured problems, the authors outline a systematic, user-friendly process for finding potential PBL topics; constructing brainstorming maps to explore the possibility of each topic becoming the focus for a PBL unit; and, then, designing the student's role, the situation he or she meets at the opening of the unit, and the unit's assessments.

Full textAbstract:
Invasion biology has been quickly expanding in the last decades so that it is now metaphorically flooded with publications, concepts, and hypotheses. Among experts, there is no clear consensus about the relationships between invasion concepts, and almost no one seems to have a good overview of the literature anymore. Similar observations can be made for other research fields. Science needs new navigation tools so that researchers within and outside of a research field as well as science journalists, students, teachers, practitioners, policy-makers, and others interested in the field can more easily understand its key ideas. Such navigation tools could, for example, be maps of the major concepts and hypotheses of a research field. Applying a bibliometric method, we created such maps for invasion biology. We analysed research papers of the last two decades citing at least two of 35 common invasion hypotheses. Co-citation analysis yields four distinct clusters of hypotheses. These clusters can describe the main directions in invasion biology and explain basic driving forces behind biological invasions. The method we outline here for invasion biology can be easily applied for other research fields.

<p><strong>Abstract.</strong> A terrain sketch map can effectively describe the terrain features and spatial pattern of a landscape, which are sketched with lines by a geographer after recognizing, analyzing and summarizing the features of a terrain scene to present his/her understanding of a landscape (Bao 1956, Chen 1958, Liu 1988). Compared with a digital elevation model (DEM) scene map, a terrain sketch map, as a scientific abstraction and expression of geomorphological features from the perspective view, is characterized by conciseness and profoundness to show the intrinsic features of a landscape. With the rapid development of computer visualization and digital terrain analysis methods, computer-assisted terrain sketches based on DEM may be automatically generated, depending on geographic cognition theory and the sketch description method.</p><p> Previous research has generated terrain scene maps based on DEM data and has produced various styles of terrain maps, i.e. oil painting, ink painting, pen and pencil sketch maps (Visvalingam et al. 1998, Whelan et al. 2003, Way et al. 2006, Bhattacharjee et al. 2008). However, those computer-drawn sketch maps have focused on the artistic effect rather than depicting terrain features and landform structures. Moreover, the area used for sketch mapping in those researches was relatively small, and visual hierarchy was not considered. Thus, those maps differ considerably from hand-drawn sketch maps by geographers or geologists. Therefore, this paper aims to generate terrain sketch map which can express terrain features as well as artistic effect.</p><p> In this study, one loess ridge-hill area (Wuqi) in the loess plateau of China was selected by considering the typicality of the geomorphic types and the availability of data. The 5&thinsp;m resolution DEM data was obtained from the National Administration of Surveying, Mapping and Geoinformation, with an area of 102&thinsp;km<sup>2</sup>.</p><p> Three aspects as terrain features, visual hierarchy and feature generalization were considered in this paper.</p><p> Firstly, the typical terrain features must be presented in the sketch map. The loess shoulder line, bank gully lines and surface flow lines in loess landform area were extracted (Yang et al. 2017, Yang et al. 2018). Then based on the Bresenham algorithm (Bresenham 1965), the visual outlines in perspective view were generated.</p><p> Secondly, the visual hierarchy is considered in this study. In a terrain sketch map, more topographically-detailed information is described in the near view, whereas only the approximate outlines and less topographical information are displayed in the distant view. Therefore, a self-adapted visual hierarchy division method was proposed. The scenes are visually divided into three levels, i.e. near view, medium view and distant view. Different numbers and types of terrain features are assigned to each visual level to obtain the effect of clear near and blurred distant views.</p><p> Thirdly, in complexity terrain area, the scene will not only look staggered and messy, but will also affect topographic recognition even only visual outlines are displayed in distant view. Therefore a method of combining DEM and visual watershed generalization was proposed to simplify the visual outlines in distant view.</p><p> Finally, the terrain sketch map is assessed and verified through a questionnaire survey which includes three specialist experts, seven graduate students and twelve undergraduate students with knowledge in geomorphology or geography.</p><p> The result show that the important feature lines added to the terrain sketch map could effectively help to recognize the typical landform characteristics in the loess plateau of China. The severity of soil erosion by gullies are obviuosly presented (Fig.1d) comparing to the sketch mapping with only visual outlines (Fig1b). The map look messy and unsigtly if all the terrain feature lines were put into the map (Fig.1c). By considering the law of air perspective, the visual hierarchy was divided and the visual outlines in the distant view was generalized, thereby realizing the characteristics of a terrain sketch map clear in near view and blurred in distant view (Fig.1d). It also showed from the questionnaire that DEM resolution influence the performance of our method especially with coarse resolution DEM. The experts suggested that filter noise in near view and generalisation in distant view can be further improved.</p>

AbstractOver the last ten years, molecular biologists and computer scientists have experimented with various artificial intelligence techniques, notably knowledge based and expert systems, qualitative simulation, natural language processing and various machine learning techniques. These techniques have been applied to problems in molecular data analysis, construction of advanced databases and modelling of biological systems. Practical results are now being obtained, notably in the representation and recognition of genetically significant structures, the assembly of genetic maps and prediction of the structure of complex molecules such as proteins. The paper outlines the principal methods used, surveys the findings to date, and identifies promising trends and current limitations.

A mais recente versão da teoria da confiabilidade tem sido utilizada para descrever a capacidade de um sistema de medição em detectar, identificar e remover outliers a um certo nível de probabilidade. Entretanto, as aplicações desta teoria têm sido direcionadas para redes simuladas de nivelamento. Aqui, por outro lado, aplicamos a teoria no contexto de redes baseadas nos sistemas de posicionamento por satélites GNSS (Global Navigation Satellite System), a partir de dados reais coletados em campo. Testamos se as covariâncias entre as componentes da linha base têm efeito sobre a confiabilidade. Verificamos que as covariâncias entre as componentes da linha base aumentam a taxa de sucesso na identificação de outlier e, portanto, aumentam a confiabilidade da rede. O menor outlier identificável – ao nível de 80% de correta identificação – teve uma redução média de ~30% para as componentes ΔX e ΔY, e ~14% para ΔZ em comparação ao cenário com covariâncias nulas. O aumento do nível de significância melhora a confiabilidade em ambos os cenários (covariâncias nulas e não-nulas) na mesma proporção. Porém, para altos níveis de significância (α > 0,1) e sistemas com boa redundância (ri > 0,5), a confiabilidade para um modelo estocástico com covariâncias nulas se aproxima do caso em que as covariâncias não são nulas. Na ausência de um modelo estocástico mais realista (covariâncias não-nulas) e para sistemas com boa redundância local (ri > 0,5), deve-optar por regiões críticas maiores ( k < 2,8).

Soil erosion is a form of land degradation. It is the process of moving surface soil with the action of external forces such as wind or water. Tillage also causes soil erosion. As outlined by the United Nations Sustainable Development Goal (UN SDG) #15, it is a global challenge to “combat desertification, and halt and reverse land degradation and halt biodiversity loss.” In order to advance this goal, we studied and modeled the soil erosion depth of a typical watershed in Taiwan using 26 morphometric factors derived from a digital elevation model (DEM) and 10 environmental factors. Feature selection was performed using the Boruta algorithm to determine 15 factors with confirmed importance and one tentative factor. Then, machine learning models, including the random forest (RF) and gradient boosting machine (GBM), were used to create prediction models validated by erosion pin measurements. The results show that GBM, coupled with 15 important factors (confirmed), achieved the best result in the context of root mean square error (RMSE) and Nash–Sutcliffe efficiency (NSE). Finally, we present the maps of soil erosion depth using the two machine learning models. The maps are useful for conservation planning and mitigating future soil erosion.

The basic idea behind multivariate cryptography is to choose a system of polynomials which can be easily inverted (central map). After that one chooses two affine invertible maps to hide the structure of the central map. Fellows and Koblitz outlined a conceptual key cryptosystem based on the hardness of POSSO. Let Fp s be a finite field of p s elements, where p is a prime number, and s ∈ N, s ≥ 1. In this paper, we used the act of GLn (Fp s ) on the set F n p s and the transformations group, to present the public key cryptosystems based on the problem of solving a non-linear system of polynomial equations

Theory of Change diagrams are commonly used within evaluation. Due to their popularity and flexibility, Theories of Change can vary greatly, from the nuanced and nested, through to simplified and linear. We present a methodology for building genuinely holistic, complexity-appropriate, system-based Theory of Change diagrams, using Participatory Systems Mapping as a starting point. Participatory System Maps provide a general-purpose resource that can be used in many ways; however, knowing how to turn their complex view of a system into something actionable for evaluation purposes is difficult. The methodology outlined in this article gives this starting point and plots a path through from systems mapping to a Theory of Change evaluators can use. It allows evaluators to develop practical Theories of Change that take into account feedbacks, wider context and potential negative or unexpected outcomes. We use the example of the energy trilemma map presented elsewhere in this special issue to demonstrate.

Full textAbstract:
Two geographic information system (GIS) techniques for displaying, analyzing, and interpreting geophysical data were recently applied at two archaeological sites in northern New Zealand; a pre-European Maori pa (fortification), and a late nineteenth-century European fortification. A GIS was used to stretch and filter the conductivity data from the pa to accentuate subtle contrasts and clearly delineate boundaries between areas with contrasting conductivity readings. Magnetic susceptibility data and two different bands of conductivity data from the historic fort were used as input for a GIS-based unsupervised classification. The classification delineated five spatial entities, several of which corresponded to known archaeological features. The interpretability of the geophysical data in relation to conventional visual analysis of conductivity contour maps was enhanced through the use of the GIS procedures outlined.

As part of the implementation initiatives undertaken by the Indiana Department of Transportation Research Division, this paper presents the effort made to identify potential issues arising from traffic data processing and to assess technologies and data needs to meet the requirements of traffic design inputs in the Mechanistic–Empirical Pavement Design Guide. Global Positioning Systems (GPSs) and geographical information system (GIS) technologies were proposed to manage weigh-in-motion (WIM) and automatic vehicle classification site information and manipulate the traffic design input database. Computer programs were developed to process the raw data ASCII files generated from a WIM vendor's software. A platform was developed to combine GPS coordinates, GIS base maps, data processing programs, and the traffic database into an integral unit. Three WIM sites were selected for trial study. It was demonstrated that, with this platform, the WIM sites and database can be accessed visually and more efficiently. In addition, the computer programs can save significant data processing time. Other issues, such as the possible effect of unclassified vehicle count, were identified. On the basis of findings from the implementation initiatives, necessary efforts and future implementation activities are outlined.

The European Commission outlined the energy-related products (ErPs) meant to be labelled and regulated in order to achieve the goals to reduce the European amount of CO2-emissions by 20% by 2020 compared to projections. Machine tools (MTs) fulfill all mandatory criteria to be categorized as ErP, namely: significant sales volume, significant environmental impact and significant improvement potential. However, the energy consumption and energy efficiency of MTs strongly depend on their utilization. A generic evaluation approach for quantifying a MT’s energy efficiency is still under development by the working group ISO/TC 39/WG 12, which drives forward the ISO 14955 series for environmental evaluation of MTs.This work presents an approach for a generic energy efficiency evaluation of MTs. Component-specific behavior is investigated and aggregated in order to entirely describe the power consumption of a MT for any utilization by power mapping. Power maps contain all possible operational scenarios under the condition of the component boundaries. The approach allows a generic MT evaluation independent on the utilization and forms the base for future MT energy efficiency labelling. The presented approach is applied and validated in a practical case study.

AbstractThis article demonstrates the construction of earthquake and volcano damage indices using publicly available remote sensing sources and data on the physical characteristics of events. For earthquakes we use peak ground motion maps in conjunction with building type fragility curves to construct a local damage indicator. For volcanoes we employ volcanic ash data as a proxy for local damages. Both indices are then spatially aggregated by taking local economic exposure into account by assessing nightlight intensity derived from satellite images. We demonstrate the use of these indices with a case study of Indonesia, a country frequently exposed to earthquakes and volcanic eruptions. The results show that the indices capture the areas with the highest damage, and we provide overviews of the modeled aggregated damage for all provinces and districts in Indonesia for the time period 2004 to 2014. The indices were constructed using a combination of software programs—ArcGIS/Python, Matlab, and Stata. We also outline what potential freeware alternatives exist. Finally, for each index we highlight the assumptions and limitations that a potential practitioner needs to be aware of.

Unmanned aerial vehicle (UAV) low-altitude remote sensing technology has recently been adopted in China. However, mapping accuracy and production processes of true digital orthophoto maps (TDOMs) generated by UAV images require further improvement. In this study, ground control points were distributed and images were collected using a multi-rotor UAV and professional camera, at a flight height of 160 m above the ground and a designed ground sample distance (GSD) of 0.016 m. A structure from motion (SfM), revised digital surface model (DSM) and multi-view image texture compensation workflow were outlined to generate a high-precision TDOM. We then used randomly distributed checkpoints on the TDOM to verify its precision. The horizontal accuracy of the generated TDOM was 0.0365 m, the vertical accuracy was 0.0323 m, and the GSD was 0.0166 m. Tilt and shadowed areas of the TDOM were eliminated so that buildings maintained vertical viewing angles. This workflow produced a TDOM accuracy within 0.05 m, and provided an effective method for identifying rural homesteads, as well as land planning and design.

Abstract. Regularly occurring flood events do have a history in Santiago de Chile, the capital city of Chile and study area for this research. The analysis of flood events, the resulting damage and its causes are crucial prerequisites for the development of risk prevention measures. The goal of this research is to empirically investigate the vulnerability towards floods in Santiago de Chile as one component of flood risk. The analysis and assessment of vulnerability is based on the application of a multi-scale (individual, household, municipal level) set of indicators and the use of a broad range of data. The case-specific set of indicators developed in this study shows the relevant variables and their interrelations influencing the flood vulnerability in the study area. It provides a decision support tool for stakeholders and allows for monitoring and evaluating changes over time. The paper outlines how GIS, census, and remote sensing data as well as household surveys and expert interviews are used as an information base for the derivation of a vulnerability map for two municipalities located in the eastern part of Santiago de Chile. The generation of vulnerability maps representing the two different perspectives of local decision makers (experts) and affected households is exemplified and discussed using the developed methodology.

The Environmental Noise Directive (Directive 2002/49/EC) obliged competent authorities to prepare strategic noise maps (SNM) and actions plans (AP) for the major roads, railways, airports and agglomerations with more than 100 000 inhabitants. Both SNM and AP have to be updated every five years, that is why procedures of creating, using and administrating of SNM and AP can be considered as constant processes. These processes are very complex and require specialized knowledge and practical skills within noise mapping area and connected with them proper experience of SNM usage and AP enforcement. Unfortunately as experience shows, Polish administrators of SNM are not competent enough to meet these requirements. The problem outlined above has become the basis to develop web-based system for knowledge transfer to SNM administrators, covering such key issues as: the preparation of guidelines for SAM, gathering the appropriate input data for acoustic model and the subsequent verification of developed SAM.

Seismogeological conditions are characterized. The structural model of sedimentary cover up to the top of the Lower Cambrian is developed. 5 seismic sequences are identified, maps of their thicknesses are presented. Proveniances of Mesozoic, Permian, Carboniferous, Devonian, Silurian, Ordovician and Middle-Upper Cambrian deposits are outlined. The structure of the Vilyuy hemisyneclise sedimentary cover is shown on deep seismic-geological sections constructed on the basis of the detailed velocity model, as well as taking into account modern and retrospective geological and geophysical data. The limited development of Devonian deposits in the inner parts of the hemisyneclise is shown, where, according to modern seismic data, the Cambrian is predicted under Carboniferous deposits, and seismic facies characteristic of the Kempendyay rift zone deposits are absent in the wave fields of the pre-Permian part of the section.

Full textAbstract:
The IUCN Sampled Red List Index (SRLI) is a policy response by biodiversity scientists to the need to estimate trends in extinction risk of the world's diminishing biological diversity. Assessments of plant species for the SRLI project rely predominantly on herbarium specimen data from natural history collections, in the overwhelming absence of accurate population data or detailed distribution maps for the vast majority of plant species. This creates difficulties in re-assessing these species so as to measure genuine changes in conservation status, which must be observed under the same Red List criteria in order to be distinguished from an increase in the knowledge available for that species, and thus re-calculate the SRLI. However, the same specimen data identify precise localities where threatened species have previously been collected and can be used to model species ranges and to target fieldwork in order to test specimen-based range estimates and collect population data for SRLI plant species. Here, we outline a strategy for prioritizing fieldwork efforts in order to apply a wider range of IUCN Red List criteria to assessments of plant species, or any taxa with detailed locality or natural history specimen data, to produce a more robust estimation of the SRLI.

Full textAbstract:
Laser-generated ultrasound is a modern non-destructive testing technique. It has been investigated over recent years as an alternative to classical ultrasonic methods, mainly in industrial maintenance and quality control procedures. In this study, the detection and reconstruction of internal defects in a metallic sample is performed by means of a time-frequency analysis of ultrasonic waves generated by a laser-induced thermal mechanism. In the proposed methodology, we used wavelet transform due to its multi-resolution time frequency characteristics. In order to isolate and estimate the corresponding time of flight of eventual ultrasonic echoes related to internal defects, a density-based spatial clustering was applied to the resulting time frequency maps. Using the laser scan beam’s position, the ultrasonic transducer’s location and the echoes’ arrival times were determined, the estimation of the defect’s position was carried out afterwards. Finally, clustering algorithms were applied to the resulting geometric solutions from the set of the laser scan points which was proposed to obtain a two-dimensional projection of the defect outline over the scan plane. The study demonstrates that the proposed method of wavelet transform ultrasonic imaging can be effectively applied to detect and size internal defects without any reference information, which represents a valuable outcome for various applications in the industry.

Full textAbstract:
Abstract Automatic suspected lesion extraction is an important application in computer-aided diagnosis (CAD). In this paper, we propose a method to automatically extract the suspected parotid regions for clinical evaluation in head and neck CT images. The suspected lesion tissues in low contrast tissue regions can be localized with feature-based segmentation (FBS) based on local texture features, and can be delineated with accuracy by modified active contour models (ACM). At first, stationary wavelet transform (SWT) is introduced. The derived wavelet coefficients are applied to derive the local features for FBS, and to generate enhanced energy maps for ACM computation. Geometric shape features (GSFs) are proposed to analyze each soft tissue region segmented by FBS; the regions with higher similarity GSFs with the lesions are extracted and the information is also applied as the initial conditions for fine delineation computation. Consequently, the suspected lesions can be automatically localized and accurately delineated for aiding clinical diagnosis. The performance of the proposed method is evaluated by comparing with the results outlined by clinical experts. The experiments on 20 pathological CT data sets show that the true-positive (TP) rate on recognizing parotid lesions is about 94%, and the dimension accuracy of delineation results can also approach over 93%.

Full textAbstract:
Although the increase in the frequency and intensity of disasters assigns a key role to disaster risk management in current debate on sustainable development, the efforts of national and local authorities to develop risk-informed planning strategies and increase disaster preparedness are still limited. In multi-hazard urban environments, the main criticality to support risk-informed planning strategies is the persisting lack of effective knowledge bases focused on the vulnerability of exposed assets to different hazards. Hence, this contribution, according to the first priority of the Sendai Framework for Disaster Risk Reduction—understanding disaster risk—and by tidying up methods and indicators developed in both EU research projects and scientific studies devoted to multi-risk and vulnerability assessment, aims at better using available knowledge to guide risk-informed spatial planning. In detail, an indicator-based method to carry out a comprehensive exposure and vulnerability analysis has been outlined and tested on a case study area, the multi-hazard urban area of Campi Flegrei, located in the western part of the metropolitan city of Naples in the South of Italy. The proposed method may contribute to the building up of an effective risk knowledge base, enabling planners to easily access information on exposure and vulnerabilities to different hazards, and to differently combine them into output maps capable of supporting risk- informed planning strategies.

Full textAbstract:
The monitoring of waste disposal sites is important in order to minimize leakages of biogas, produced by anaerobic digestion and potentially explosive and detrimental to the environment. In this research, thermal imaging from unmanned aerial vehicles (UAVs) has been proposed as a diagnostic tool to monitor urban landfills. Since the anaerobic decomposition produces heat along with biogas, thermal anomalies recorded over the soil are likely to be associated with local biogas escaping from the landfill terrain and leaving a local thermal print. A simple and novel approach, based only on the processing of thermal maps gathered by the remote sensing surveys, has been proposed for the estimation of the fugitive methane emissions from landfills. Two case studies, concerning two Italian landfills, have been presented. For one of them (Mount Scarpino, Genoa), significant thermal anomalies were identified during several UAV flights and the relevant thermal images processed to obtain a rough estimation of the associated methane leakages. For the second landfill (Scala Erre, Sassari), the thermal map did not reveal any anomaly attributable to local biogas emission. Despite some limitations outlined in the paper, the present approach is proposed as an innovative method to identify significant biogas leakages from an urban landfill and to provide a preliminary evaluation of the methane production potential.

Urban road traffic spatio-temporal characters reflect how citizens move and how goods are transported, which is crucial for trip planning, traffic management, and urban design. Video surveillance camera plays an important role in intelligent transport systems (ITS) for recognizing license plate numbers. This paper proposes a spatio-temporal visualization method to discover urban road vehicle density, city-wide regional vehicle density, and hot routes using license plate number data recorded by video surveillance cameras. To improve the accuracy of the visualization effect, during data analysis and processing, this paper utilized Internet crawler technology and adopted an outlier detection algorithm based on the Dixon detection method. In the design of the visualization map, this paper established an urban road vehicle traffic index to intuitively and quantitatively reveal the traffic operation situation of the area. To verify the feasibility of the method, an experiment in Guiyang on data from road video surveillance camera system was conducted. Multiple urban traffic spatial and temporal characters are recognized concisely and efficiently from three visualization maps. The results show the satisfactory performance of the proposed framework in terms of visual analysis, which will facilitate traffic management and operation.

Solar energy is the most clean renewable energy source and has good prospects for future sustainable development. Installation of solar photovoltaic (PV) systems on building rooftops has been the most widely applied method for using solar energy resources. In this study, we developed an approach to simulate the monthly and annual solar radiation on rooftops at an hourly time step to estimate the solar PV potential, based on rooftop feature retrieval from remote sensing images. The rooftop features included 2D rooftop outlines and 3D rooftop parameters retrieved from high-resolution remote sensing image data (obtained from Google Maps) and digital surface model (DSM, generated from the Pleiades satellite), respectively. We developed the building features calculation method for five rooftop types: flat rooftops, shed rooftops, hipped rooftops, gable rooftops and mansard rooftops. The parameters of the PV modules derived from the building features were then combined with solar radiation data to evaluate solar photovoltaic potential. The proposed method was applied in the Chao Yang District of Beijing, China. The results were that the number of rooftops available for PV systems was 743, the available rooftop area was 678,805 m2, and the annual PV electricity potential was 63.78 GWh/year in the study area, which has great solar PV potential. The method to perform precise calculation of specific rooftop solar PV potential developed in this study will guide the formulation of energy policy for solar PV in the future.

Full textAbstract:
The Danish Central Graben is part of the mainly Late Jurassic complex of grabens in the central and southern North Sea which form the Central Graben. The tectonic elements of the Danish Central Graben in the Late Jurassic are outlined and compared to those in the Early Cretaceous based on reduced versions of published maps (1:200 000), compiled on the basis of all 1994 public domain seismic and well data. The Tail End Graben, a half-graben which stretches for about 90 km along the East North Sea High, is the dominant Late Jurassic structural feature. The Rosa Basin (new name) is a narrow, north–south-trending basin extending from the south-western part of the Tail End Graben. The Tail End Graben ceased to exist as a coherent structural element during the Early Cretaceous and developed into three separate depocentres: the Iris and Gulnare Basins to the north and the Roar Basin to the south (new names). The Early Cretaceous saw a shift from subsidence focused along the East North Sea High during the Late Jurassic to a more even distribution of minor basins within the Danish Central Graben. The depth to the top of the Upper Jurassic – lowermost Cretaceous Farsund Formation reaches a maximum of 4800 m in the northern part of the study area, while the depth to the base of the Upper Jurassic reaches 7500 m in the Tail End Graben, where the Upper Jurassic attains a maximum thickness of 3600 m. The Lower Cretaceous Cromer Knoll Group attains a maximum thickness of 1100 m in the Outer Rough Basin.

The reception in the United States of Medellín in the wider context of the follow-up to the Second Vatican Council has been wide and deep in terms of several developments outlined here. Faith-based social ministries in Hispanic/Latino communities in the form of grass root community organizations in the tradition of Saul Alinsky found inspiration in Medellin’s option for the poor and pastoral de conjunto. Many other examples of Medellín’s impact are placed in the wider historical context of the past fifty years, the half century in which Hispanics/Latinos emerged as the majority of U.S. Catholics under the age of 35.RESUMO: Este artigo investiga a forma pela qual tanto o evento como o documento de Medellín tiveram papel significativo na evolução dos ministérios pastorais e sociais da população de origem latino-americana dos Estados Unidos nos últimos cinquenta anos.

Full textAbstract:
Our study aimed to investigate whether radiomics on MRI sequences can differentiate responder (R) and non-responder (NR) patients based on the tumour regression grade (TRG) assigned after surgical resection in locally advanced rectal cancer (LARC) treated with neoadjuvant chemoradiotherapy (nCRT). Eighty-five patients undergoing primary staging with MRI were retrospectively evaluated, and 40 patients were finally selected. The ROIs were manually outlined in the tumour site on T2w sequences in the oblique-axial plane. Based on the TRG, patients were grouped as having either a complete or a partial response (TRG = (0,1), n = 15). NR patients had a minimal or poor nCRT response (TRG = (2,3), n = 25). Eighty-four local first-order radiomic features (RFs) were extracted from tumour ROIs. Only single RFs were investigated. Each feature was selected using univariate analysis guided by a one-tailed Wilcoxon rank-sum. ROC curve analysis was performed, using AUC computation and the Youden index (YI) for sensitivity and specificity. The RF measuring the heterogeneity of local skewness of T2w values from tumour ROIs differentiated Rs and NRs with a p-value ≈ 10−5; AUC = 0.90 (95%CI, 0.73–0.96); and YI = 0.68, corresponding to 80% sensitivity and 88% specificity. In conclusion, higher heterogeneity in skewness maps of the baseline tumour correlated with a greater benefit from nCRT.

Flooding has become one of the most rapidly growing types of natural disaster that has spread around the globe. It is is one of the major natural hazards in many countries and mostly affected in the low-lying or flood prone areas. In order to minimize loss of life and economic losses, a detailed and comprehensive decision making tool is necessary for both flood control planning and emergency service operations. In this paper, we demonstrate our research design for mobile based decision support of Flood Early Warning System (FEWS). We outlined four research objectives. Firstly, critical criteria for flood risk assessment will be identified and the second step will involve develop measurement model for relative flood risk using Geographic Information System (GIS), Multi Attribute Decision Making (MADM) and data mining technique. In the third objectives, the holistic architectural design is develop by incorporating the communication technology and other related ICT requirements for the mobile decision support. The fourth objective is to validate the mathematical model and architectural design. Case study approach is chosen in order to understand the flood event and validate the decision support model. Following well-defined procedures, flood maps were drawn based on the data collected from expert responses to a questionnaire, the field survey, satellite images, and documents from flood management agencies. It is anticipates that by integrating of mathematical model, GIS and mobile application in flood risk assessment could provide useful detailed information for flood risk management, evacuation, communication. The decision support design from this study is perhaps to improve the warning system and contribute to reduction of casualties.

Abstract. Thermal anomaly detection has an important role in remote sensing. One of the most widely used instruments for this task is a Thermal InfraRed (TIR) camera. In this work, thermal anomaly detection is formulated as a salient region detection, which is motivated by the assumption that a hot region often attracts attention of the human eye in thermal infrared images. Using TIR and optical images together, our working hypothesis is defined in the following manner: a hot region that appears as a salient region only in the TIR image and not in the optical image is a thermal anomaly. This work presents a two-step classification method for thermal anomaly detection based on an information fusion of saliency maps derived from both, TIR and optical images. Information fusion, based on the Dempster-Shafer evidence theory, is used in the first phase to find the location of regions suspected to be thermal anomalies. This classification problem is formulated as a multi-class problem and is carried out in an unsupervised manner on a pixel level. In the following phase, classification is formulated as a binary region-based problem in order to differentiate between normal temperature variations and thermal anomalies, while Random Forest (RF) is chosen as the classifier. In the seconds phase, the classification results from the previous phase are used as features along with temperature information and height details, which are obtained from a Digital Surface Model (DSM). We tested the approach using a dataset, which was collected from a UAV with TIR and optical cameras for monitoring District Heating Systems (DHS). Despite some limitations outlined in the paper, the presented innovative method to identify thermal anomalies has achieved up to 98.7 percent overall accuracy.

Full textAbstract:
Abstract Sinkholes are inherent features of the karst terrain of Greene County, Missouri, that present hazards and engineering challenges to construction/infrastructure development. Analysis of relationships between the spatial distribution of sinkholes and possible influencing factors can help in understanding the controls involved in the formation of sinkholes. The spatial analysis outlined herein can aid in the assessment of potential sinkhole hazards. In this research, Geographic Information System–based ordinary least squares regression (OLS) and geographically weighted regression (GWR) methods were used to determine and evaluate principal factors appearing to influence the formation and distribution of karst sinkholes. From the OLS result, seven out of 12 possible influencing factors were found to exert significant control on sinkhole formation processes in the study area. These factors are overburden thickness, depth to groundwater, slope of the ground surface, distance to the nearest surface drainage line, distance to the nearest geological structure (such as faults or folds), distance to the nearest road, and distance to the nearest spring. These factors were then used as independent variables in the GWR model. The GWR model examined the spatial non-stationarity among the various factors and demonstrated better performance over OLS. GWR model coefficient estimates for each variable were mapped. These maps provide spatial insights into the influence of the variables on sinkhole densities throughout the study area. GWR spatial analysis appears to be an effective approach to understand sinkhole-influencing factors. The results could be useful to provide an objective means of parameter weighting in models of sinkhole susceptibility or hazard mapping.

The article outlines the directions of the ecological safety formation on the territory of IvanoFrankivsk urban system according to acoustic and electromagnetic load factors. In order to provide an acoustically comfortable environment for inhabitants of the urban system the authors solved the following tasks: measurements of the equivalent sound level along the highways and near the residential buildings close to the roads were made; special attention was paid to the public transport stops where the audio-boxes of the "Street Radio " are located. In general, an equivalent sound level Leqv was measured at 165 points within the territory of Ivano-Frankivsk urban system. According to the research results separate zones (streets) with the greatest acoustic discomfort within the city were allocated, profiles of acoustic load distribution along main streets were built, taking into account the equivalent sound level in the green zones of the city which are located nearby. Using the software program Surfer a noise map for the territory of Ivano-Frankivsk was built. To ensure a comfortable living environment within the urban system according to the factor of electromagnetic load the following tasks were solved: isotropic measurements of the electromagnetic field components at 122 points of the test-ground were carried out. At each point in terms of maximum and average values the following parameters were measured: electric field strength (E, V/m); magnetic field strength (H, mA/m); surface energy flux density (W, mkW/cm2). Base cellular network stations were recorded, their contribution to the electromagnetic situation of the city was described. The maps of technogenic electromagnetic pollution were built with the help of the program Surfer for the spatial analysis of changes in the electromagnetic field levels within the urban system. Spline interpolation method was used to build the maps. Moreover, measurements of 5 basic test objects of the urban system were carried out, which are the most vulnerable to the electromagnetic field influence. According to the research results the schematic images of the electromagnetic field distribution inside the objects were built. The most sensitive zones within the test objects were determined. Thus, according to the analysis of the conducted research favorable zones for comfortable and safe residence in Ivano-Frankivsk urban system according to the factors of noise and electromagnetic pollution were determined.

As análises lingüísticas têm exibido, majoritariamente, desde o estruturalismo, uma inclinação por modelos de produção. Pouca atenção tem sido dada à percepção. Além disso, a variação lingüística não tem sido a preocupação maior dos modelos teóricos propostos. Na verdade, ela tem sido excluída da maioria deles. Recentemente a teoria fonológica vem se ocupando da variação lingüística, mas, novamente, pendendo pela produção (na maioria das vezes) ou pela percepção. O que se pretende, aqui, é oferecer um esboço de modelo teórico que seja capaz, a partir da junção da produção com a percepção, de lidar com os fatos da variação. O modelo, operacionalizável em termos dos mecanismos da Teoria da Otimalidade, pretende, com base em princípios mais gerais da língua, alocar a variação num nível abstrato (percepção) e deixar a sua implementação (produção), no uso, sensível ao par {indivíduo-item lexical}.PALAVRAS-CHAVE: Teoria Fonológica. Variação lingüística. Percepção. Produção. OT.ABSTRACTLinguistic analyses have shown, beginning with the structuralist school, a major tendency towards production models, with little attention to perception. Besides this, linguistic variation has not been one of the main subjects of these theoretical models; in fact it has been excluded from most of them. It is only recently that phonological theory has turned its attention to linguistic variation but, again, either to production, most of the time, or to perception, in a few cases. It is our goal here to draw an outline of a theoretical model which is capable to deal with the facts of variation from the standpoint of production and perception. This model, which can be formalized in terms of the OT apparatus, and on the basis of general principles of the language, intends to allocate variation to an abstract level (perception) and let its implementation (production), in language use, sensitive to the pair {individual-lexical item}.

Abstract Background Inflammatory bowel diseases (IBD) are chronic relapsing diseases of unknown etiology, usually beginning at a young age. Although life expectancy of IBD patients is near to the mean of healthy population, IBD has a significantly negative impact on patients’ quality of life. Recent research has evidenced that a poorer quality of life can contribute to relapse or worsening of IBD symptoms, reduce treatment adherence and lead to poorer outcomes. The Ezkerraldea-Enkarterri-Cruces Healthcare Organization in Spain has made a firm commitment to adopt the Value-Based Health Care (VBHC) model, which advocates for the incorporation of patient-perceived quality of life variables to the items we normally assess. The IBD Unit, in pursuit of adhering to the VBHC corporate programme, has launched on a process to analyze our health care delivery system and improve the effectiveness of our Performance Improvement Plan based on patients’ experience. Objectives: - To identify and systemize the incorporation of perceived quality of life variables - To reorient medical care towards what really matters to patients Methods We have built a multi-disciplinary team comprised of healthcare professionals involved in IBD management (Figure 1). Patients form the core of the team’s meetings, helping in the development of User Experience (Figure 2) and Empathy Maps (Figure 3) by using Design Thinking strategies. After the detection of the obstacles faced by patients, we outlined a Process Map (Figure 4), where we critically analyzed the route followed by patients in our health-care system before reaching the IBD Unit. Subsequently, a specific route was outlined considering the set proposed for the disease by the ICHOM consortium as a reference framework. Questionnaires and surveys were designed using patient information across different areas of care, in order to guarantee the correct functioning of the route. Results We obtained a list of 14 improvement proposals which are currently at different levels of evaluation. In our first year, we have been able to implement important modifications which include: - A specific remote consultation for IBD patients - Fast track pathways - Nutritional guidelines to assure compliance - Shortening waiting lists - Reduction in patient bureaucracy and paperwork - Virtual monitorization of patients with asymptomatic disease Conclusion - VHBC implementation implies a transformation of the organization - User Experience tools add a different perspective to the route design, focusing on what really matters to patients and improving their quality of life - This change of perspective is important, especially in chronic diseases, so that patients feel less lonely with their disease and better outcomes can be obtained
