Published: May 2022

Exercise is known to be beneficial in the management of chronic low back pain (LBP), especially in pain reduction and improving function. Core stability exercise (CSE) is fast becoming the foremost exercise in the management of LBP; however, it is presently undetermined whether CSEs produces more valuable effects than stretching exercises in the management of LBP. The study aimed to review the effectiveness of CSEs or stretching exercises in the management of chronic LBP. A systematic review of randomized clinical trials was done using published articles. Multiple databases and specific journal websites were searched to obtained original researches published between 2000 and 2021 in which pain and disability were evaluated as outcomes. Methodological quality was assessed using the Physiotherapy Evidence Database scale and none of the included studies had scores of <9/10. Three studies met the criteria for this review. The included studies randomized participants into two different exercise groups. One out of the three studies showed benefits of CSE over stretching exercises for pain and disability. Another study showed ST exercise is more beneficial to CSE for pain and disability while the last study shows both CSE and ST exercises to be effective in pain and disability management. In conclusion compared to ST exercise, CSE is not more effective in pain reduction and improved physical function in individuals with LBP in the short term. However, no follow-up assessments were done postintervention.
Pseudociencia y sociedad en España
Authors: Cortiñas-Rovira S , Salvador-Mata B
Published: May 2022

Pseudociencia y sociedad en España. Estado de la cuestión e investigaciones recientes analyses the communicative strategies that pseudoscience uses for its social ex-pansion. This work begins with the definition of an epistemological framework that allows us to understand the phenomenon of pseudoscience and its rela-tionship with the main factors of contemporary society, such as relativism and liquidity. As a consequence of the postmodern condition, absolute certainties vanish and the possibility of not only ignoring science but even denying it be-comes real. In this sense, one of the main theses of this work is that the over-informed, postmodern and liquid society favours the expansion of pseudo-scientific discourses. Spain, like most countries, is no stranger to this expan-sion. To confirm this hypothesis, different social groups have been analysed to a) identify the degree of insertion of pseudoscience in these contexts; b) describe and categorise the communicative elements present in pseudoscien-tific discourses; and c) propose lines of action to limit the rise of these dis-courses. The present research has covered science journalists, literature, libraries, universities and different representatives of the biomedical field, such as pharmacists and healthcare professionals. Mixed methodologies have been applied: in-depth interviews to identify discursive patterns, content analysis, data analysis, and focus groups. Among the main conclusions, the followings stand out: 1) Pseudoscience uses fallacy, relativism, emotional reinforcement, opposition to a supposed dogmatic concept of science, antiquity, holistic or naturalistic arguments, among others to expand. 2) Pseudoscience normalizes its social discourse through its appearance in different contexts, in some cases openly, and in others in a discourse of risk minimization that favours its nor-malization as something innocuous. As a whole, the pseudoscientific discourse represents a challenge for scientific communication that must be addressed using all the communicative tools available.

Published: May 2022

Meckel's diverticulum (MD)1, the most common congenital anomaly of the gastrointestinal tract, occurs in 2% of the population with males being more symptomatic than females.  In this case, a 32-year-old male presented with sudden onset colicky abdominal pain, bilious vomiting, and absolute constipation. Emergency laparotomy was done on his virgin abdomen, as a result MD and vitelline cyst along with a fibrous cord connecting the two were identified. Knotting of an ileal loop around this cord had resulted in intestinal obstruction. Meckel’s diverticulectomy, along with cord resection, was carried out. The patient made smooth recovery and was discharged on the fifth postoperative day with no complications. The importance of this study is to highlight the case of symptomatic MD in an adult male as it can be a cause of intestinal obstruction and should always be considered in a patient presenting with symptoms of intestinal obstruction.

Published: May 2022

Kabupaten Lombok Utara secara geografis termasuk dalam kawasan rawan bencana, salah satunya adalah gempa bumi. Gempa yang  terjadi pada tahun 2018 di Kecamatan Pemenang Kabupaten Lombok Utara disebabkan oleh Sesar Naik Flores atau Flores Back Arc Thrust. Dampak dari gempa besar tersebut adalah banyak rumah warga yang rusak berat. Salah satu penyebab terjadinya kerusakan hebat pada saat gempa adalah tidak terpenuhinya kaidah teknis bangunan, seperti lemahnya sambungan struktur dan kualitas bangunan yang rendah. Kerusakan lebih banyak disebabkan karena pembangunan yang dilakukan oleh masyarakat tidak sesuai dengan kaidah pembangunan rumah yang layak, penggunaan kolom, balok dan ring balok tidak sesuai dengan standar teknis dan bahkan ada rumah yang dibuat tidak menggunakan pembesian. Membangun kembali kawasan pascabencana tidaklah mudah. Pelaksanaan rehabilitasi dan rekonstruksi harus dilakukan dengan perhitungan dan perencanaan yang matang. Selain dua hal tersebut, aspek terpenting yang harus diperhitungkan adalah keterlibatan warga yang menjadi korban bencana, maka dari itu masyarakat harus dilibatkan dalam proses pembangunan kembali pemukiman berbasis komunitas yang berorientasi pada pengurangan resiko bencana. Berdasarkan permasalahan tersebut perlu dilakukan pendampingan rehabilitasi dan rekonstruksi rumah tahan gempa berbasis komunitas. Kelompok masyarakat yang telah terbentuk diharapkan dapat memberikan edukasi kepada masyarakat terkait dengan cara pembangunan rumah tahan gempa. Perencanaan dan pelaksanaan perbaikan rumah korban bencana harus mengacu peta potensi gempa dikemudian hari, oleh karena itu standar kekuatan bangunan harus dipahami oleh masyarakat sesuai dengan standar teknis Kementrian PUPR. Dengan adanya pendampingan ini diharapkan dapat membantu masyarakat dalam merekonstruksi bangunan rumah yang rusak akibat gempa sesuai standar kekuatan bangunan sehingga jika terjadi bencana/kejadian serupa dapat meminimalkan jumlah korban

The use of plant extract in the control of seed borne fungal pathogen has been found to be economically and environmentally friendly and as well as easily biodegradable. This study was carried out to investigate the effect of plant extracts, Alligator pepper (Aframomum melegueta) and Neem (Azadirachta indica) on the seed borne fungal pathogen of sweet pepper Capsicum annum (Otuocha and Nsukka). Capsicum annum seeds were extracted for seed health test using blotter paper method. Seed borne fungal pathogen (Aspergillus spp. Fusarium spp.) were identified. The potential for these organisms for pathogenicity were tested using Kock’s postulate. The antifungal effects of ethanol and acetone extracts of the test plants were studied under in- vitro experiment against the seed borne fungal pathogen (Fusarium solani) of Capsicum annum at 0%, 50% and 75% concentration using synthetic fungicide (Benlate) as a standard control. The design was a 3x3 factorial laid out in a Completely Randomized Design (CRD) with three replications. Data collected were subjected to analysis of variance (ANOVA) and means were separated with Fishers’ Least Significant Difference (FLSD) at 5% probability level. Ninety percent germination was obtained in the viability test of Nsukka pepper. The result of the pathogenicity test showed that the organisms isolated were pathogenic. All plant extracts (Aframomum melegueta) and Neem (Azadirachta indica) and Benlate inhibited radial growth of the test fungus. Azadirachta indica and Benlate inhibited the growth of Fusarium solani for three days in culture, though Azadirachta indica performed better than Benlate. The inhibition was also greater as concentration increased from 50% to 75% concentration level. The result of this study showed that the plant extract Azadirachta indica, which is naturally more abundant and readily available could be explored as an eco-friendly alternative to synthetic fungicide (Benlate) in the control of Fusarium solani on sweet pepper varieties since it performed as much as the synthetic fungicide.

Selama masa pandemi COVID-19, upaya penanganan TB menjadi terhambat. Upaya penanganan TB saat masa pandemi dapat dilakukan dengan memanfaatkan teknologi digital. Yayasan KNCV Indonesia (YKI) bersama Kemenkes RI mengembangkan aplikasi dalam mendukung program TB yaitu SOBAT TB dan EMPATI Client. Kedua aplikasi tersebut memiliki fungsi yang sama yaitu untuk upaya eliminasi TB namun aplikasi tersebut tidak disatukan sehingga pelayanan tidak terintegrasi. Oleh karena itu, diperlukan adanya penggabungan antara aplikasi SOBAT TB dan EMPATI Client, pembaruan pada aplikasi SOBAT TB dengan menambahkan berbagai fitur (pasien dapat mengunduh catatan perawatannya dan laporan analitik dari perawat, kemudian dapat membuat jadwal minum obat dengan dosis harian atau dengan dosis intermittent, fitur penghantaran obat dan penghantaran spesimen dahak) serta melakukan pengembangan di IOS & Website. Kemudian melakukan kerjasama dengan jasa ojek online untuk dapat mendukung fitur penghantaran obat dan mengantarkan spesimen dahak. Sasaran bagi pengguna aplikasi dapat diperluas tidak hanya ditujukan bagi pasien TB RO saja tetapi untuk seluruh pasien TB dan masyarakat umum. Selain itu, diperlukan penyebarluasan informasi terkait aplikasi SOBAT TB kepada masyarakat dan Dinas Kesehatan sehingga diharapkan cakupan penggunaan aplikasi semakin luas dan dapat menjadi solusi dan upaya dalam eliminasi TB di masa pandemi.

Risks, prevalence and management of carpal tunnel syndrome amidst Somatologists within the Western Cape
Authors:   , Kistoor Charne
Published: May 2022

Carpal Tunnel Syndrome (CTS) has been recognised for many decades across various industries and researched extensively in these domains. The practice of Somatology has greatly evolved from the beauty therapy industry of past years that simply focussed on aesthetic techniques of beautifying clients. The new techniques and general physical demands of the somatologist profession, however, raise concerns for the health and wellness of the somatologist. This research was motivated by the lack of data available on musculoskeletal disorders generally, and specifically, the prevalence among somatologists in the Western Cape of carpal tunnel syndrome. The study objectives were to determine the general prevalence of CTS among qualified somatologists in the Western Cape, to identify risk factors that contribute to the development of CTS in somatologists, and to determine current preventative measures and management of CTS among somatologists. A quantitative research approach was used to evaluate the objectives by collecting the data, using a questionnaire as the research tool. Various beauty schools and businesses within the field were contacted to determine the prevalence rate of qualified somatologists being diagnosed with CTS. A sample group of somatologists who had worked or were working in the Western Cape was recruited to the study and the questionnaire included openended questions to elicit more detailed responses beyond the statistical data. The results of the study indicated CTS is generally prevalent in the beauty therapy industry and has debilitating long-term consequences for the health and career longevity of somatologists, many of whom have to prematurely leave their chosen career paths due to their development of CTS, or to divert income to treatment costs in an industry where earnings are typically low. The study highlighted several issues that require further and wider study, such as compensation for injury, access to medical aid or employer subsidies, inherent health risks in the nature of some treatments and the need for more education and possible adjustments to training to prevent or alleviate the onset of CTS. Such future studies should provide insight for companies within the industry to aid their revision of policies and procedures to better facilitate and support somatologists suffering from CTS.

A osteorradionecrose (ORN) dos maxilares é uma consequência secundária das mais graves em pacientes submetidos a radioterapia de cabeça e pescoço. Trata-se de uma doença na qual o osso irradiado torna-se desvitalizado e exposto através da perda da integridade da pele e da mucosa, persistindo sem cicatrização. O objetivo do presente trabalho foi revisar a literatura sobre o manejo preventivo e terapêutico da ORN dos maxilares. O estudo constitui-se em uma revisão de literatura elaborada através do levantamento bibliográfico nas bases de dados da PubMed e Biblioteca Virtual da Saúde (BVS), utilizando os termos descritores “osteorradionecrose”, “radioterapia” e “assistência odontológica”. Foram identificados aspectos relacionados à prevenção e as diversas formas de tratamento da ORN, tais como oxigenoterapia hiperbárica, abordagem farmacológica e cirúrgica. Concluiu-se, por meio das informações obtidas na literatura, que a prevenção ainda é a melhor conduta, sendo o cirurgião-dentista um dos profissionais fundamentais nesse contexto. Com relação ao tratamento, observa-se que normalmente há uma combinação de medidas conservadoras e ressecção cirúrgica, sendo que a mais utilizada é a antibioticoterapia tópica ou sistêmica.

Abstract. Agricultural soil erosion, both mechanical and eolic, may impact
cloud processes, as some aerosol particles are able to facilitate ice crystal formation. Given the large agricultural sector in Mexico, this study investigates the ice nucleating abilities of agricultural dust collected at different sites and generated in the laboratory. The immersion freezing mechanism of ice nucleation was simulated in the laboratory via the Universidad Nacional Autónoma de México (UNAM) microorifice
uniform deposit impactor (MOUDI) droplet freezing technique (DFT), i.e.,
UNAM-MOUDI-DFT. The results show that agricultural dust from the Mexican
territory promote ice formation in the temperature range from
−11.8 to −34.5 ∘C, with ice nucleating particle (INP) concentrations between 0.11 and 41.8 L−1. Furthermore, aerosol samples generated in the laboratory are more efficient than those collected in the field, with T50 values (i.e., the temperature at which 50 % of the droplets freeze) higher by more than 2.9 ∘C. Mineralogical analysis indicated a high concentration of feldspars, i.e., K-feldspar and plagioclase (>40 %), in most of the aerosol and soil samples, with K-feldspar significantly correlated with the T50 of particles with aerodynamic diameters between 1.8 and 3.2 µm. Similarly, the organic carbon (OC) was correlated with the ice nucleation efficiency of aerosol samples from 3.2 to 5.6 and from 1.0 to 1.8 µm. Finally, a decrease in INP efficiency after heating the samples at 300 ∘C for 2 h indicates that the organic matter from agricultural soils plays a predominant role in the ice nucleating abilities of this type of aerosol sample.

Abstract. Brown carbon (BrC) aerosols exert vital impacts on climate change and atmospheric photochemistry due to their light absorption in the wavelength range from near-ultraviolet (UV) to visible light. However, the optical properties and formation mechanisms of ambient BrC remain poorly understood, limiting the estimation of their radiative forcing. In the present study, fine particles (PM2.5) were collected
during 2016–2017 on a day/night basis over urban Tianjin, a megacity in northern China. Light absorption and fluorescence properties of water extracts of PM2.5 were investigated to obtain seasonal and diurnal patterns of atmospheric water-soluble BrC. There were obvious seasonal, but no evident
diurnal, variations in the light absorption properties of BrC. In winter, BrC showed much stronger light-absorbing ability, with a mass absorption efficiency at 365 nm (MAE365) in winter (1.54±0.33 m2 gC−1) that was 1.8 times larger than MAE365 in summer (0.84±0.22 m2 gC−1). Direct radiative effects by BrC absorption relative to black carbon in the UV range were 54.3±16.9 % and 44.6±13.9 % in winter and summer, respectively. In addition, five fluorescent components in BrC, including three humic-like fluorophores and two protein-like fluorophores were identified with excitation–emission matrix fluorescence spectrometry and parallel factor (PARAFAC) analysis. The less oxygenated components contributed more to winter and nighttime samples, while more oxygenated components increased in summer and daytime samples. The higher humification index (HIX), together with lower biological index (BIX) and fluorescence index (FI), suggests that the chemical compositions of BrC were associated with a high aromaticity degree in summer and daytime due to photobleaching. Fluorescent properties indicate that wintertime BrC were predominantly affected by primary emissions and fresh
secondary organic aerosol (SOA), while summer ones were more influenced by aging processes. Results of source apportionments using organic molecular compositions of the same set of aerosols reveal that fossil fuel combustion and aging processes, primary bioaerosol emission, biomass burning, and
biogenic and anthropogenic SOA formation were the main sources of BrC. Biomass burning contributed much more to BrC in winter and at nighttime, while biogenic SOA contributed more in summer and during the daytime. In particular, our study highlights that primary bioaerosol emission is an important source of BrC in urban Tianjin in summer.
The impact of large-scale circulation on daily fine particulate matter (PM2.5) over major populated regions of China in winter

Published: May 2022

Abstract. Using a new high-resolution air quality reanalysis dataset for China for
five winters from December 2013 to February 2018, we examine the influence
of large-scale circulation on daily PM2.5 variability through its
direct effect on key regional meteorological variables over three major
populated regions of China: Beijing–Tianjin–Hebei (BTH), the Yangtze River
Delta (YRD) and the Pearl River Delta (PRD). In BTH, a shallow East Asian
trough curbs northerly cold and dry air from the Siberian High, enhancing
PM2.5 pollution levels. Weak southerly winds in eastern and southern
China, associated with a weakened Siberian High, suppress horizontal
dispersion, contributing to air pollution accumulation over YRD. In PRD,
weak southerly winds and precipitation deficits over southern China are
conducive to high PM2.5 pollution levels. To account for these
dominant large-scale circulation–PM2.5 relationships, we propose
three new circulation-based indices for predicting different levels of air
pollution based on regional PM2.5 concentrations in each region: a
500 hPa geopotential height-based index for BTH, a sea level pressure-based
index for YRD and an 850 hPa meridional wind-based index for PRD. These
three indices can effectively distinguish clean days from heavily polluted
days in these regions, assuming variation is solely due to meteorology. We
also find that including the most important regional meteorological variable
in each region improves the performance of the circulation-based indices in
predicting daily PM2.5 concentrations on the regional scale. These
results are beneficial to understanding and forecasting the occurrence of
heavily polluted PM2.5 days in BTH, YRD and PRD from a large-scale
perspective.
Intraseasonal variation of the northeast Asian anomalous anticyclone and its impacts on PM2.5 pollution in the North China Plain in early winter
Authors: An Xiadong , Chen Wen , Hu Peng , Chen Shangfeng , Sheng Lifang
Published: May 2022

Abstract. The canonical view of the northeast Asian anomalous anticyclone (NAAA) is a crucial factor for determining poor air quality (i.e., higher particulate matter, PM2.5 concentrations) in the North China Plain (NCP) on
the interannual timescale. However, there is considerable intraseasonal
variability in the NAAA in early winter (November–January), and the
corresponding mechanism of its impacts on PM2.5 pollution in the NCP is
not well understood. Here, we find that the intraseasonal NAAA usually
establishes quickly on day 3 prior to its peak day with a duration of 8 d, and its evolution is closely tied to the Rossby wave from upstream
(i.e., the North Atlantic). Moreover, we find that the NAAA with a westward
tilt might be mainly related to the wavenumbers 3–4. Further results
reveal that against this background, the probability of regional PM2.5
pollution for at least 3 d in the NCP is as high as 69 % (80 % at
least 2 d) in the Nov–Jan (NDJ) period 2000–2021. In particular, air quality in the
NCP tends to deteriorate on day 2 prior to the peak day and reaches a peak
on the next day with a life cycle of 4 d. In the course of PM2.5
pollution, a shallower atmospheric boundary layer and stronger surface
southerly wind anomaly associated with the NAAA in the NCP appear 1 d
earlier than poor air quality, which provides dynamic and thermal conditions
for the accumulation of pollutants and finally occurrence of the PM2.5
pollution on the following day. Furthermore, we show that the stagnant air
leading to poor air quality is determined by the special structure of
temperature in the vertical direction of the NAAA, while weak ventilation
conditions might be related to a rapid build-up of the NAAA. The present
results quantify the impact of the NAAA on PM2.5 pollution in the NCP
on the intraseasonal timescale.

Abstract. Cloud shadows are observed by the TROPOMI satellite instrument as a result of its high spatial resolution compared to its predecessor instruments. These shadows contaminate TROPOMI's air quality measurements, because shadows are generally not taken into account in the models that are used for aerosol and trace gas retrievals. If the shadows are to be removed from the data, or if shadows are to be studied, an automatic detection of the shadow pixels is needed. We present the Detection AlgoRithm for CLOud Shadows (DARCLOS) for TROPOMI, which is the first cloud shadow detection algorithm for a spaceborne spectrometer. DARCLOS raises potential cloud shadow flags (PCSFs), actual cloud shadow flags (ACSFs), and spectral cloud shadow flags (SCSFs). The PCSFs indicate the TROPOMI ground pixels that are potentially affected by cloud shadows based on a geometric consideration with safety margins. The ACSFs are a refinement of the PCSFs using spectral reflectance information of the PCSF pixels and identify the TROPOMI ground pixels that are confidently affected by cloud shadows. Because we find indications of the wavelength dependence of cloud shadow extents in the UV, the SCSF is a wavelength-dependent alternative for the ACSF at the wavelengths of TROPOMI's air quality retrievals. We validate the PCSF and ACSF with true-colour images made by the VIIRS instrument on board Suomi NPP orbiting in close proximity to TROPOMI on board Sentinel-5P. We find that the cloud evolution during the overpass time difference between TROPOMI and VIIRS complicates this validation strategy, implicating that an alternative cloud shadow detection approach using co-located VIIRS observations could be problematic. We conclude that the PCSF can be used to exclude cloud shadow contamination from TROPOMI data, while the ACSF and SCSF can be used to select pixels for the scientific analysis of cloud shadow effects.
NORMAL CLASSIFICATION OF 3D OCCUPANCY GRIDS FOR VOXEL-BASED INDOOR RECONSTRUCTION FROM POINT CLOUDS
Authors: Hübner P. , Wursthorn S. , Weinmann M.
Published: May 2022

Abstract. In this paper, we present an automated method for classification of binary voxel occupancy grids of discretized indoor mapping data such as point clouds or triangle meshes according to normal vector directions. Filled voxels get assigned normal class labels distinguishing between horizontal and vertical building structures. The horizontal building structures are further differentiated into those with normal directions pointing upwards or downwards with respect to the building interior. The derived normal grids can be deployed in the context of an existing voxel-based indoor reconstruction pipeline, which so far was only applicable to indoor mapping triangle meshes that already contain normal vectors consistently oriented with respect to the building interior. By means of quantitative evaluation against reference data, we demonstrate the performance of the proposed method and its applicability in the context of voxel-based indoor reconstruction from indoor mapping point clouds without normal vectors. The code of our implementation is made available to the public at https://github.com/huepat/voxir.
ASSESSING CADASTRE 2034 TO DEVELOP A FEDERATED CADASTRAL SYSTEM IN NEW SOUTH WALES AUSTRALIA: MIXED METHODS RESEARCH APPROACH
Authors: Sigley T. J. , Paudyal D. R.
Published: May 2022

Abstract. Cadastre 2034 is a National Strategy developed by the Intergovernmental Committee on Surveying and Mapping (ICSM) for cadastral reform and innovation for Australia and one of the goals is to develop a federated cadastral system. It states to define governance and administration on a federal level by unifying the existing systems with uniform standards, policies, guidelines and legislation and to allow further work towards a global cadastre. The aim of this research paper is to explore the behaviours and attitudes of New South Wales (NSW) cadastre towards a federated cadastral system assessing the best practice of federated cadastre global cases that may be applied locally in Australia. Mixed Methods Research (MMR) methodology was used, involving both quantitative and qualitative research to understand, identify and frame the cadastral data to determine and analyse the key issues and factors in implementing a federated cadastral system in New South Wales (NSW). A literature review, a questionnaire survey and interviews were used to collect the quantitative and qualitative data. A sequential MMR design framework was used a questionnaire survey followed by interviews. The questionnaire was sent out to 215 industry and government participants and resulted 71 completed surveys. Semi-structured interviews were conducted with 9 participants. The linking of quantitative and qualitative data occurred at the design-level, where results from the first phase were used to build the second phase of research design.It was explored that strong historical foundations, regressive reaction of governments and institutions, and a lack of understanding of the significance of cadastral reform were the key hindering factors to develop a federated cadastral system in NSW. The resulting analysis could be contributed to a better implementation of a federated cadastral system in NSW benefitting private, and public institutions.
MULTI-RESOLUTION REPRESENTATION USING GRAPH DATABASE
Authors: Huang Y. , Stefanakis E.
Published: May 2022

Abstract. Multi-resolution representation has always been an important and popular data source for many research and applications, such as navigation, land cover, map generation, media event forecasting, etc. With one spatial object represented by distinct geometries at different resolutions, multi-resolution representation is high in complexity. Most of the current approaches for storing and retrieving multi-resolution representation are either complicated in structure, or time consuming in traversal and query. In addition, supports on direct navigation between different representations are still intricate in most of the paradigms, especially in topological map sets. To address this problem, we propose a novel approach for storing, querying, and extracting multi-resolution representation. The development of this approach is based on Neo4j, a graph database platform that is famous for its powerful query and advanced flexibility. Benefited from the intuitiveness of the proposed database structure, direct navigation between representations of one spatial object, and between groups of representations at adjacent resolutions are both available. On top of this, collaborating with the self-designed web-based interface, queries within the proposed approach truly embraced the concept of keyword search, which lower the barrier between novice users and complicate queries. In all, the proposed system demonstrates the potential of managing multi-resolution representation data through the graph database and could be a time-saver for related processes.
PROJECTIVE MULTITEXTURING OF CURRENT 3D CITY MODELS AND POINT CLOUDS WITH MANY HISTORICAL IMAGES
Authors: Gomes de Castro M. S. , Brédif M.
Published: May 2022

Abstract. Iconographic image collections are a cultural heritage that could reach a larger audience by proposing their immersive presentation in a 3D web application. Proposing a historical street view application, based on these historical images, raises issues such as the unavailability of historical 3D models of the scene and the heterogeneity and sparsity of these photographs. We propose to use the 3D city and terrain models of the current scene, as well as a 3D point cloud if available, to simultaneously reproject and blend many historical images using an image-based rendering approach. Our contributions raise significantly the number of projective textures blended per rendering pass (typically from 8 to 40) on triangular meshes (of the 3D city and terrain models) and on point clouds. As a first step to tackle diachrony artifacts, we also propose a simple point cloud classification to filter in the shader the points corresponding to building or terrain details from the points corresponding to transient objects.

Abstract. As a place to live, work and play, urban spaces are the nerve centers of human activity. The urban spaces, which are becoming increasingly extensive and dense, are particularly sensitive to the effects of climate change. Greening cities has been identified as one of the most effective ways to mitigate one of these effects, the urban heat island. In this context, the city of Liège, Belgium, has adopted a greening plan, called “Plan canopée”, to increase the tree canopy area at city level. The aim of this study is to present the methodology used to objectivize and prioritize the selection of potential planting sites. This research proposes the production of a series of spatial indicators allowing, on the one hand, the precise mapping of urban surfaces ready for planting, and on the other hand, the objective prioritization of city districts to be vegetated. The research integrates airborne image classification, urban heat island modeling and a series of reference geodata combinations. The set of data produced provides a transparent decision support tool to the authorities for the operational planning of tree plantations. These results contribute to the development of a planting strategy that maximizes the chances of ownership by the citizens, and consequently the sustainable and effective impact of the achievements.
ASSESSING GEO-TYPICAL TECHNIQUES FOR MODELING BUILDINGS USING THERMAL SIMULATIONS

Published: May 2022

Abstract. Building modeling from remote sensing data is essential for creating accurate 3D and 4D digital twins, especially for temperature modeling. In order to represent buildings as gap-free, visually appealing, and rich in details models, geo-typical prototypes should be represented in the scene. The sensor data and freely available OSM data are supposed to provide guidelines for best-possible matching. In this paper, the default similarity function based on intersection over union is extended by terms reflecting the similarity of elevation values, orientation towards the road, and trees in the vicinity. The goodness of fit has been evaluated by architecture experts as well as thermal simulations with a thermal image as ground truth and error measures based on mean average error, root mean square and mutual information. It could be concluded that while intersection over union measure still seems to be most preferred by architects, slightly better thermal simulation results are yielded by taking into account all similarity functions.
SPATIAL VARIATION ANALYSIS OF LOCAL POPULATION DATA AND LOCAL HOUSEHOLD-SIZE DATA FOR URBAN MANAGEMENT IN A DECLINING POPULATION

Published: May 2022

Abstract. In Japan, population decline is one of the important issues that need to be tackled in socioeconomic fields. We apply an analysis method composed of a spatial autocorrelation analysis to the local population data and the local household-size data generated through the 1995 and 2015 national census, and detect their spatial dynamics in this study. Under the concept that the application of local population and local household can detect the details of the spatial features of population decline, we newly define an index regarding the size of an area where lower local mean sizes of households are distributed in urbanized areas, in addition to the spatial local-population index defined previously. It is shown that the local population dynamics are described by the combination of the variations of the 2 indices between 1995 and 2015.
EVALUATION METHOD FOR INFORMATION CONTENT OF RASTER DATA USING FRACTAL DIMENSION
Authors: Osaragi T.
Published: May 2022

Abstract. Raster data are obtained by dividing an entire study area into a regular grid of cells. Hence, raster data information depends on cell size as well as the shapes of geographical features to be rasterized. In this paper, we report on the construction of a method for evaluating the information content obtained from raster data using information theory. We also provide some numerical examples showing that the resulting information content can be expressed as a logistic function of cell size and that its parameters can be written as simple linear models with the fractal dimensions of the geographic features to be rasterized.
