Authors: Díaz Ricardo , Marulanda Felipe
Published: September 2019

Introducción: el dolor crónico es uno de los síntomas que más afectan la funcionalidad y calidad de vida de quienes lo padecen. En Colombia son escasos los estudios sobre su comportamiento epidemiológico y clínico.

Objetivo: estimar la prevalencia y aspectos clínicos del dolor crónico nociceptivo y neuropático en una muestra representativa de la ciudad de Manizales.

Metodología: se entrevistaron 627 personas mayores de 18 años de ambos sexos, seleccionadas al azar en diferentes barrios de la ciudad de Manizales, aplicando un cuestionario semiestructurado, mediante entrevista domiciliaria realizada por estudiantes de la Facultad de Ciencias para la Salud. La información fue procesada mediante el paquete estadístico Epi-Info.

Resultados: se encontró una prevalencia de dolor crónico de 33.9%, correspondiendo al tipo nociceptivo el 31.4% y al neuropático el 2.5%. Hubo predominio del género femenino para ambos tipos de dolor y para el nociceptivo la frecuencia aumentó con la edad. La localización más frecuente fue la cabeza en el nociceptivo y los miembros superiores para el neuropático. La duración del dolor fue mayor a un año en dos terceras partes de los sujetos y superior a cinco años en la tercera parte de ellos. La mitad de las personas con dolor crónico reportaron compromiso significativo del estado de ánimo, y una tercera parte afectación del patrón de sueño. La medicación predominante en ambos tipos de dolor fueron AINES y acetaminofén, con escaso consumo de opiodes. El 41% de los entrevistados reportó autoformulación. La escala de tamizaje de dolor neuropático (DN4) resultó útil para la identificación de sujetos con este tipo de dolor y mostró capacidad de discriminación frente al dolor nociceptivo, dependiendo de la inclusión o no de los items del examen físico.

Conclusiones: esta investigación confirma la alta prevalencia de dolor crónico en la población adulta y su tendencia a persistir a través de los años, con repercusión negativa en los aspectos emocionales, sueño y calidad de vida. Se resalta la necesidad de un adecuado diagnóstico y manejo individual, apropiadas políticas en salud y permanente desarrollo investigativo para enfrentar esta importante condición

Information on smooth swallowing posture and swallowing function training is described in the medical literature. A dining chair was developed in Japan to protect the elderly from aspiration and aspiration pneumonia. We thought that if the function effect of the dining chair was actually exhibited, it would be vital information to all the elderly whose swallowing function continues to decline. We tried the verification test with electromyograph about the actual functional effect of the developed dining chair. Eating with the neck forward flexion (NFF) posture by the upright pelvis fixed support has shown a smooth swallowing effect which can be valuable information to elderly people around the world, whose swallowing function continues to decline.

Now it is clear that there are an enormous number of functions in cell performing by microtubules, a structure unit of which is tubulin. Now it used widely as a predictive factor of tumor aggressiveness, but increasingly it becomes a target for studying and treatment elaboration, since it is well-known that to nowadays tubulin-targeted medicines, such as taxanes or vinca-alkaloids, resistance develops rather quickly, so it consists a large problem in oncology. This work reveals basic microtubule functions, violations that it may undergo and consequences of these. Also it is described here the main modern tendencies in creation of remedy which will make it possible breakthrough treatment resistance barrier.
Intrinsic Focal Electromagnetic Induction, a Mechanism of Neurological Symptoms
Authors: BL Rish
Published: September 2019

The physics of Electromagnetic Induction (EMI) is reviewed and applied to the anatomy and neurophysiology of the human body. The neuron, the primary cell of the nervous system, coexists with a myriad of vascular structures and would be susceptible to EMI. When the neuron’s electrical impulse, the action potential, traversing an axon with deficient myelin, intersects the electromotive fields of a blood vessel, a conductor, EMI could occur. By the laws of physics governing this phenomenon, a new current, inductance, would be produced and shared throughout the blood vessel and back into the axon source of the original current. Medical history and the study of physics support this phenomenon as the mechanism of the pain in trigeminal neuralgia, tic douloureux. Other neurological syndromes, such as seizures associated with arteriovenous malformations and causalgia seen after nerve injuries in the extremities may share this mechanism.
Obstructing calculus in a single limb of a duplicated ureter: A Recall of the surgical anatomy and the Variable Ureter Anomalies
Authors: FA Shawish , WA Shawish
Published: September 2019

The ureter is a common site of congenital anomalies which may be associated with a considerable morbidity particularly among young patient. The congenital anomalies of the ureter coexist with multitude of other urinary tract anomalies but it may occur independently. It is more common in females. The complete duplication of the ureter may not produce symptoms which would suggest the presence of malformation. Therefore, such anomaly may not become apparent until later in life. Further, this anomaly might not be recognized prior to the surgery and hence, missing of the stone is highly possible.

Herein we present a case of complete ureter duplicate with an obstructive stone located close to VUJ of one limb of the duplicate. A sound knowledge of the surgical anatomy and of the congenital ureter anomalies is essential for correct diagnosis and appropriate management.
Preliminary results of new elastic mini-nail in the distal radius fractures. First 83 cases of the nail-o-flex nail
Authors: D Persoons
Published: September 2019

The distal radius fracture is a common injury in old persons. His treatment remains a critical challenge because of number of cases, the final cost of the procedure, the level of X-rays irradiation and a demanding technic of fixation in osteoporotic bone. The entire closed procedure requires a strict percutaneous nailing. This offers advantages in terms of post-operative pain, per-operative irradiation and cost. The main problem was so far the ability to insure a stable reduction in time. This point is discussed with the introduction of the “Nail-oflex®” nail. A continuous series of 83 patients is introduced.
Prendre part aux logiques d’exclusion : les mobilisations anti-migrants en France, en Italie et aux États-Unis
Authors: Simonneau Damien , Castelli Gattinara Pietro
Published: September 2019

En France, en Italie et dans l’Arizona (États-Unis), des groupes, des élus et des citoyens sont engagés dans la construction de la migration comme « problème » public. Quelles sont les actions, initiatives et stratégies discursives de ces entrepreneurs de cause anti-migrants ? La démarche comparative révèle la convergence des discours et des modes d’action tout en soulignant les différentes modalités d’articulation de ces acteurs dans leurs systèmes politiques respectifs. Les deux enquêtes menées en Arizona, pour l’une, en Italie et en France, pour l’autre, permettent d’identifier trois types d’opposition à l’immigration : des actions directes contre l’arrivée de migrants, se nourrissant d’un discours de l’abandon de l’État ; des actions qui ont trait à l’élaboration d’un savoir organisé commun à l’ensemble du mouvement ; des actions visant à produire une réaction politique, dans le but de mettre à l’agenda le contrôle migratoire et frontalier. Il convient dès lors de déterminer ce qui, dans ces actions, relève du vigilantisme, de l’action collective ou de l’action publique.
Jeunes travailleuses et travailleurs de la production engagée : articuler activité professionnelle et convictions dans un engagement professionnalisé
Authors: Rodet Diane
Published: September 2019

Cet article s’intéresse aux jeunes travailleurs et travailleuses de la production engagée, définie comme une activité de production exprimant explicitement des positions militantes. À partir de plusieurs terrains relevant de l’économie solidaire d’une part, et du cas de l’entreprise en ligne La Ruche qui dit Oui !, d’autre part, il met au jour des individus recherchant de nouvelles formes de travail et/ou d’emploi. Ceux-ci ont des profils proches et partagent le fait de vouloir articuler convictions et rémunération dans un engagement « professionnalisé ». Dès le début de leur vie professionnelle, ces travailleurs et travailleuses recherchent un travail qui ait du « sens », celui-ci passant par la défense d’une cause. Une partie de ces jeunes associe à cette revendication le rejet du salariat et la recherche d’un cadre d’emploi mêlant autonomie et flexibilité.
La distance de jeunes salariés vis-à-vis des « voies du collectif »
Authors: Trémeau Camille
Published: September 2019

En nous appuyant sur une enquête menée auprès de jeunes coiffeusesesthéticiennes, ouvriers du bâtiment et informaticiens, nous interrogeons le rapport des jeunes salariés aux représentants du personnel et aux syndicats, dans des secteurs marqués par une faible syndicalisation. Les jeunes salariés rencontrés ne comptent pas parmi les plus touchés par la précarité. Toutefois, ils n’en évoluent pas moins dans des configurations professionnelles défavorables à l’exploration des « voies du collectif » et, plus précisément ici, de la représentation des salariés. L’article met ainsi en évidence la diversité des mécanismes qui creusent une distance entre ces jeunes salariés et les instances représentatives du personnel (IRP), et nuance l’idée d’un rejet des représentants du personnel et des syndicats, qui ne constitue en fait qu’une seule variante de l’attitude de distance. Du point de vue des jugements portés à l’égard du syndicalisme, une entrée par la socialisation permet de rendre compte de représentations hétérogènes et socialement situées de la conflictualité et de la lutte.

The association between under-nutrition, school performance and perceptual motor functioning in first-grade South African learners: The North-West Child Health Integrated with Learning and Development study
Authors: Pienaar Anita E.
Published: September 2019

Background: Early childhood is characterised by an immense spurt of growing and learning where under-nutrition can have adverse effects on the neuro-developmental health and school performance of children. A full understanding of the relationship between school performance and motor functioning skills and malnourishment in school beginners is still lacking.Aim: To determine the association between indices of under-nutrition and how it relates to school performance and motor functioning skills of first-grade learners.Setting: North West province (NWP) of South Africa (SA).Method: The baseline data of the stratified, randomised North-West Child Health Integrated with Learning and Development (NW-CHILD) longitudinal study were used. Grade 1 learners (N = 816, 420 boys, 396 girls, mean age 6.78+ years) from four school districts in the NWP of SA took part in the study. Indices of under-nutrition were determined by Z-scores (−2 standard deviation [s.d.]) for stunting (height-for-age [HAZ]) and wasting and underweight (Z-score for body mass index) using the 2007 World Health Organization reference sample. The Bruininks–Oseretsky Test of Motor Proficiency Short Form and the Visual Motor Integration fourth edition were used to assess different aspects of motor functioning, while school performance in mathematics, reading and writing was assessed by teachers according to the National South African standards of assessments.Results: Both HAZ and Z-score for weight-for-age correlated significantly with school performance and motor functioning skills (r 2.0, p 0.05), while visual perception was moderately associated (r 0.30) with mathematics in HAZ and Z-score for weight-for-height (WHZ) children. Motor functioning of HAZ and WHZ children was significantly poorer (p 0.05) compared to typical children, while underweight was not associated with any outcome variables.Conclusion: Moderate forms of stunting and wasting influence school performance and motor functioning of school beginners negatively, while an association between visual perceptual abilities and inferior mathematics, reading and writing suggests a close link with inferior cognitive information processing in stunted and wasted children. These barriers should be addressed as poor scholastic success in Grade 1 may influence future school performance and the subsequent well-being of children.
Causes and countermeasures for repeated outbreaks of hepatitis A among adults in Korea
Authors: Ki Moran , Son Hyunjin , Choi Bo Youl
Published: September 2019

The 2019 hepatitis A outbreak has become increasingly prevalent among adults in Korea and is the largest outbreak since that in 2009-2010. The incidence in the current outbreak is highest among adults aged 35-44 years, corresponding to the peak incidence among those aged 25-34 years 10 years ago. This may indicate a cohort effect in the corresponding age group. Causes of these repeated outbreaks of hepatitis A in Korea are low level of immunity among adults, Korean food culture that consumes raw seafood such as salted clam and inadequate public health system. Among countermeasures, along with general infectious disease control measures including control of the infectious agent, infection spread, and host, urgent actions are needed to review the vaccination policy and establish an adequate public health system.

VOXEL-BASED VISIBILITY ANALYSIS FOR SAFETY ASSESSMENT OF URBAN ENVIRONMENTS
Authors: Aleksandrov M. , Zlatanova S. , Kimmel L. , Barton J. , Gorte B.
Published: September 2019

Abstract. This paper presents the research and development of a volumetric 3D visibility analysis application to assess public space in regards to safety and security. While most of the academic literature on space visibility concentrates on developing viewsheds from a specific viewpoint, this work integrates dynamic scenarios and real-time calculation of space visibility. Voxel-based spatial representation is utilised as a base for the 3D visibility analysis. Different space configurations are tested illustrating the robustness and usefulness of the developed application. In order to measure and evaluate different safety zones, an innovative approach is tested according to which the number of times each voxel is observed is recorded and further classified into different zones. In this way, an accurate calculation of the observed space can be performed understanding which part of an area of interest is less or more observed. The research has shown great potential for first responders, researchers, architects and safety experts. The developed application can be used as a simulation tool to assess the safety of different urban environments and identify potentially vulnerable locations.

RAISE THE ROOF: TOWARDS GENERATING LOD2 MODELS WITHOUT AERIAL SURVEYS USING MACHINE LEARNING
Authors: Biljecki F. , Dehbi Y.
Published: September 2019

Abstract. LoD2 models include roof shapes and thus provide added value over their LoD1 counterparts for some applications such as estimating the solar potential of rooftops. However, because of laborious acquisition workflows they are more difficult to obtain than LoD1 models and are thus less prevalent in practice. This paper explores whether the type of the roof of a building can be inferred from semantic LoD1 data, potentially leading to their free upgrade to LoD2, in a broader context of a workflow for their generation without aerial campaigns. Inferring rooftop information has also other uses: quality evaluation and verification of existing data, supporting roof reconstruction, and enriching LoD0/LoD1 data with the attribute of the roof type. We test a random forest classifier that analyses several attributes of buildings predicting the type of the roof. Experiments carried out on the 3D city model of Hamburg using 12 attributes achieve an accuracy of 85% in identifying the roof type from sparse data using a multiclass classification. The performance of binary classification hits the roof: 92% accuracy in predicting whether a roof is flat or not. It turns out that the two most useful variables are footprint area and building height (i.e. LoD1 models without any semantics, or LoD0 with such information), and using only them also yields relatively accurate results.
GENERATING 3D CITY MODELS BASED ON THE SEMANTIC SEGMENTATION OF LIDAR DATA USING CONVOLUTIONAL NEURAL NETWORKS
Authors: Agoub A. , Schmidt V. , Kada M.
Published: September 2019

Abstract. Virtual city models are important for many applications such as urban planning, virtual and augmented reality, disaster management, and gaming. Urban features such as buildings, roads, and trees are essential components of these models and are subject to frequent change and alteration. It is laborious to manually build and update virtual city models, due to a large number of instances and temporal changes on such features. The increase of publicly available spatial data provides an important source for pipelines that automate virtual city model generation. The large quantity of data also opens an opportunity to use Deep Learning (DL) as a technique that minimizes the need for expert domain knowledge. In addition, many Deep Learning models calculations can be parallelized on modern hardware such as graphical processing units, which reduces the computation time substantially.We explore the opportunity of using publicly available data in computing multiple thematic data layers from Digital Surface Models (DSMs) using an automatic pipeline that is powered by a semantic segmentation network. To evaluate this design, we implement our pipeline using multiple Convolutional Neural Networks (CNN) with an encoder-decoder architecture. We produce a variety of two and three-dimensional thematic data. We focus our evaluation on the pipeline’s ability to produce accurate building footprints. In our experiments we vary the depths, the number of input channels and data resolutions of the evaluated networks. Our experiments process public data that is provided by New York City.
QUALITY OF BIM–GIS CONVERSION
Authors: Biljecki F. , Tauscher H.
Published: September 2019

Abstract. Much work has been done on quality of geoinformation and interoperability between BIM and GIS. However, the intersection of the two – quality control of the conversion between BIM and GIS – remains uncharted. This discussion paper, based on empirical results, is one of the first steps towards mapping out a framework on errors and quality control in the context of BIM–GIS interoperability. In our work we focus on the conversion from IFC to CityGML, identifying several systematic errors potentially common and/or exclusive to the context of BIM–GIS conversion. Besides exposing several faults pertaining to IFC-sourced 3D city models, we discuss their taxonomy and their potential impact when engaged in applications. This paper is also relevant with respect to the growing popularity of conversion between IFC and CityGML, potentially aiding others to avoid many of the errors that can occur in the process and establishing directions to set up a benchmark to assess the performance of the interoperability workflows.
ACTIVE SAMPLING AND MODEL BASED PREDICTION FOR FAST AND ROBUST DETECTION AND RECONSTRUCTION OF COMPLEX ROOFS IN 3D POINT CLOUDS
Authors: Dehbi Y. , Henn A. , Gröger G. , Stroh V. , Plümer L.
Published: September 2019

Abstract. 3D city models in Level-of-Detail 2 (LoD2) are nowadays inevitable for many applications such as solar radiation calculation and energy demand estimation. City-wide models are required which can solely be acquired by fully automatic approaches. In this paper we propose a novel method for the 3D-reconstruction of LoD2 buildings with structured roofs and dormers from LIDAR data. We apply a hybrid strategy which combines the strengths of top-down and bottom-up methods. The main contribution is the introduction of an active sampling strategy which applies a cascade of filters focusing on promising samples in an early stage and avoiding the pitfalls of RANSAC based approaches. Such filters are based on prior knowledge represented by (non-parametric) density distributions. Samples are pairs of surflets, i.e. 3D points together with normal vectors derived from a plane approximation of their neighborhood. Surflet pairs imply immediately important roof parameters such as azimuth, inclination and ridge height, as well as parameters for internal precision and consistency, giving a good base for assessment and ranking. Ranking of samples leads to a small number of promising hypotheses. Model selection is based on predictions for example of ridge positions which can easily be falsified based on the given observations. Our approach does not require building footprints as prerequisite. They are derived in a preprocessing step using machine learning methods, in particular Support Vector Machines (SVM).
A MULTI-HEIGHT LOD1 MODEL OF ALL BUILDINGS IN THE NETHERLANDS

Abstract. The 3D representation of buildings with roof shapes (also called LoD2) is popular in the 3D city modelling domain since it provides a realistic view of 3D city models. However, for many application block models of buildings are sufficient or even more suitable. These so called LoD1 models can be reconstructed relatively easily from building footprints and point clouds. But LoD1 representations for the same building can be rather different because of differences in height references used to reconstruct the block models and differences in underlying statistical calculation methods. Users are often not aware of these differences, while these differences may have an impact on the outcome of spatial analyses. To standardise possible variances of LoD1 models and let the users choose the best one for their application, we have developed a LoD1 reconstruction service that generates several heights per building (both for the ground surface and the extrusion height). The building models are generated for all ~10 million buildings in The Netherlands based on footprints of buildings and LiDAR point clouds. The 3D dataset is updated every month automatically. In addition, for each building quality parameters are calculated and made available. This article describes the development of the LoD1 building service and we report on the spatial analysis that we performed on the generated height values.

Abstract. The amount and the quality of 3D spatial data are growing constantly, but the data is collected and stored in a distributed fashion by various data collecting organizations. This may lead to problems regarding interoperability, usability and availability of the data. Traditionally, national spatial data infrastructures have focused on 2D data, but recently there has been great progress towards introducing also 3D spatial data in governmental services. This paper studies the process of creating a country-wide 3D data repository in Finland and visualizing it for the public by using an open source map application. The 3D spatial data is collected and stored into one national topographic database that provides information for the whole society. The data quality control process is executed with an automated data quality module as a part of the import process to the database. The 3D spatial data is served from the database for the visualization via 3D service and the visualization is piloted in the National Geoportal.

Abstract. This paper reports about an effort to generate LoD3 models of buildings semi-automatically, with the highest possible level of automation. It is work in progress. We use multi-sensor data like aerial images from a 5-head camera with a GSD of 10 cm, UAV images, and aerial and mobile LiDAR point clouds. We distinguish two cases: LoD2 models are available and they are not. We apply Multi-Photo Geometrically Constrained Least Squares Matching for different kind of point measurements. The regularity of many building façades in Singapore leads us to the idea to generalize the measurement procedure towards using measurement macros (geometrical primitives, i.e. windows, doors, etc.) and combine reality-based with procedural modelling. In parallel we try to model these façade elements from LiDAR point cloud data. In another research line we do building detection by a novel approach to land-cover classification, incorporating features of the façades to improve the classification accuracy. To generate the semantic labels of the façades, we developed a spatially unrelated mean-shift clustering method to yield structurally confined segments. It is the characteristic of automated and even semi-automated procedures that the results need some amount of editing. We therefore work on interactive post-editing approaches on CityGML building models containing semantic information of each surface. Maintaining the semantic information throughout the editing process is essential but often lack the support from current tools. Accordingly, we implement a method to synchronize CityGML models. Overall this project consists of a great number of different algorithmic components, which can only be coarsely explained in this paper.
APPLICABILITY OF NEURAL NETWORKS FOR IMAGE CLASSIFICATION ON OBJECT DETECTION IN MOBILE MAPPING 3D POINT CLOUDS

Published: September 2019

Abstract. In this work, we present an approach that uses an established image recognition convolutional neural network for the semantic classification of two-dimensional objects found in mobile mapping 3D point cloud scans of road environments, namely manhole covers and road markings. We show that the approach is capable of classifying these objects and that it can efficiently be applied on large datasets. Top-down view images from the point cloud are rendered and classified by a U-Net implementation. The results are integrated into the point cloud by setting an additional semantic attribute. Shape files can be computed from the classified points.
THE LADM-BASED 3D UNDERGROUND UTILITY MAPPING: CASE STUDY IN SINGAPORE

Published: September 2019

Abstract. A digital twin can be defined as a realistic representation of something physical. To improve decision making, a reliable digital twin of the underground is required. Utilities represent a significant portion of physical assets existing underground. Most of these utilities are situated in the relatively shallow layers of the underground, up to a few meters below the surface. The reliable information on subsurface utilities has clear benefits all throughout the life cycle of state land, resulting in efficient decision-making processes, cost savings, and additional revenues for land administration professionals. However, the lack of a reliable map of subsurface utilities lead to ill-informed decisions, costly information gathering, and missed business potential. This paper will share a case study of the 3D underground utility mapping workflow from data capture to usage in Singapore. The new data is collected by the Pegasus: Stream, a mobile mapping platform which captures above and underground data using the photo, laser and ground penetrating radar technology. Based on the Land Administration Domain Model (LADM) 3D underground utility data model, the new collected data is used with the existing utility and cadastral data for land administration. This study case expects to explore the reasonable workflow of 3D underground utility mapping to provide reliable information for land administration.
THE USE OF CCTV IN THE EMERGENCY RESPONSE: A 3D GIS PERSPECTIVE

Published: September 2019

Abstract. With the increasing threats and damages from the natural and man-made hazards, emergency response has become a critical challenge to the smart management of modern cities. Due to limited human resources, how to correctly and quickly assess the priority of disaster relief operations remains a major issue to the disaster management. While the emergency response team may continuously receive lots of disaster information from various sources, they are required to validate whether the reported situations is real or not. CCTV systems are one of the primary references for visually presenting the status in reality. However, current maps of CCTV are usually presented in 2D, such that the monitored spatial coverage is also restricted to 2D. From a 3D perspective, this paper proposes to integrate the GIS-based urban data and the field of view (FOV) of CCTV for improving the collection, management and decision making during emergency response. As the pressure for making prompt and correct decision is often overwhelming, the key issue is to find the best CCTV as soon as possible. Although the current result is only preliminary, the proposed approach demonstrates the advantages of enabling a “real” 3D spatial illustration about the spatial coverage information of CCTV systems by linking it to the features in the real world. With such standardized metadata for FOV available, further analysis can be readily developed, such as quickly determine if a feature is visible, if a reported disaster situation can be validated, and assess the area not covered by the current CCTV systems. By including the disaster events from the historical database, the proposed approach allows the responsible agencies to assess if the deployment and management of current CCTV systems can provide a satisfactory spatial coverage for the cities in the mitigation phase.
