Urban flooding has been an alarming issue in the past around the globe, particularly in South Asia. Pakistan is no exception from this situation where urban floods with associated damages are frequently occurring phenomena. In Pakistan, rapid urbanization is the key factor for urban flooding, which is not taken into account. This study aims to identify flood sensitivity and coping capacity while assessing urban flood resilience and move a step toward the initialization of resilience, specifically for Peshawar city and generally for other cities of Pakistan. To achieve this aim, an attempt has been made to propose an integrated approach named the “urban flood resilience model (UFResi-M),” which is based on geographical information system(GIS), remote sensing (RS), and the theory of analytical hierarchy process (AHP). The UFResi-M incorporates four main factors—urban flood hazard, exposure, susceptibility, and coping capacity into two parts, i.e., sensitivity and coping capacity. The first part consists of three factors—IH, IE, and IS—that represent sensitivity, while the second part represents coping capacity (ICc). All four indicators were weighted through AHP to obtain product value for each indicator. The result showed that in the Westzone of the study area, the northwestern and central parts have very high resilience, whereas the southern and southwestern parts have very low resilience. Similarly, in the East zone of the study area, the northwest and southwest parts have very high resilience, while the northern and western parts have very low resilience. The likelihood of the proposed model was also determined using the receiver operating characteristic (ROC) curve method; the area under the curve acquired for the model was 0.904. The outcomes of these integrated assessments can help in tracking community performance and can provide a tool to decision makers to integrate the resilience aspect into urban flood management, urban development, and urban planning.

Authors: Deur Martina , Gašparović Mateo , Balenović Ivan
Published: May 2021

Quality tree species information gathering is the basis for making proper decisions in forest management. By applying new technologies and remote sensing methods, very high resolution (VHR) satellite imagery can give sufficient spatial detail to achieve accurate species-level classification. In this study, the influence of pansharpening of the WorldView-3 (WV-3) satellite imagery on classification results of three main tree species (Quercus robur L., Carpinus betulus L., and Alnus glutinosa (L.) Geartn.) has been evaluated. In order to increase tree species classification accuracy, three different pansharpening algorithms (Bayes, RCS, and LMVM) have been conducted. The LMVM algorithm proved the most effective pansharpening technique. The pixel- and object-based classification were applied to three pansharpened imageries using a random forest (RF) algorithm. The results showed a very high overall accuracy (OA) for LMVM pansharpened imagery: 92% and 96% for tree species classification based on pixel- and object-based approach, respectively. As expected, the object-based exceeded the pixel-based approach (OA increased by 4%). The influence of fusion on classification results was analyzed as well. Overall classification accuracy was improved by the spatial resolution of pansharpened images (OA increased by 7% for pixel-based approach). Also, regardless of pixel- or object-based classification approaches, the influence of the use of pansharpening is highly beneficial to classifying complex, natural, and mixed deciduous forest areas.

Published: May 2021

Robotics is a disruptive technology that will change diagnostics and treatment protocols in dental medicine. Robots can perform repeated workflows for an indefinite length of time while enhancing the overall quality and quantity of patient care. Early robots required a human operator, but robotic systems have advanced significantly over the past decade, and the latest medical robots can perform patient intervention or remote monitoring autonomously. However, little research data on the therapeutic reliability and precision of autonomous robots are available. The present paper reviews the promise and practice of robots in dentistry by evaluating published work on commercial robot systems in dental implantology, oral and maxillofacial surgery, prosthetic and restorative dentistry, endodontics, orthodontics, oral radiology as well as dental education. In conclusion, this review critically addresses the current limitations of dental robotics and anticipates the potential future impact on oral healthcare and the dental profession.

Published: May 2021

Currently, there are more than 1.55 million cases of SARS-CoV-2 infection in Spain. Of these, it is estimated that around 45% will present respiratory complications, which represents approximately 620,000 patients who will need respiratory rehabilitation. The health system has no resources for this huge quantity of patients after the hospital discharge to finish the complete recovery and avoid the chronicity of the symptoms. We propose an application named RespiraConNosotros. The application has been created and designed to guide users in performing respiratory rehabilitation exercises, especially for COVID-19 patients, and it also facilitates patient–physiotherapist contact via chat or video calling to help patients. It is accessible for all users and on all devices. All exercises would be guided and supervised by a specialized physiotherapist who suggests, adapts, and guides the exercise according to the function level of each patient. Data obtained was satisfactory; all patients pointed out the easy access, the intuitive format, and the advantage of communicating with an expert. Concerning functional assessment, all participants improved their score on the Borg scale after performing the intervention with the application.This platform would help respiratory patients to make rehabilitation treatments to recover their pulmonary function and to decrease or eliminate the possible complications they have. It never substitutes any prescribed treatment. In conclusion, RespiraConNosotros is a simple, viable, and safe alternative for the improvement and maintenance of respiratory capacity and patient’s functionality affected by COVID-19. It could be used as a complement to face-to-face treatment when the situation allows it.

Published: May 2021

The present work provides the first records on microplastic (MP) amounts and types in rivers and wastewater effluents entering the Aegean Sea, eastern Mediterranean. Two rivers were sampled using a manta net (mesh size, 0.33 mm): a small urban and a medium-sized river with a rural, semiurban catchment. MPs in wastewater samples were collected at two wastewater treatment plants (WWTPs) within the Athens metropolitan area after secondary treatment and from a pilot biological membrane unit (MBR), using a series of sieves. MPs in the samples were identified using stereoscopic image analysis and spectroscopic techniques. MP concentrations in the rivers were found to be variable, with as high as 27.73 items m−3 in the urban river. Differences in MP shape types, sizes, and polymer types reflect catchment size and usage. MP concentration in wastewater effluents was found to be 100 times higher in the secondary treatment (213 items m−3) than that in the pilot MBR (2.29 items m−3), with filaments and polymers indicative of synthetic textiles and household use. Further research is needed in order to accurately determine variability in MP concentrations and fluxes from these two pathways in the eastern Mediterranean Sea and elucidate the role of rivers in MP retention.
Towards Evidence Based Policy Making in GIAHS: Convention Theory and Effects of GIAHS Registration on the Wholesale and Retail Trade of Traditional and Local Vegetables
Authors: Miyake Yoshitaka , Uchiyama Yuta , Fujihira Yoshinori , Kohsaka Ryo
Published: May 2021

This study examines how the registration of certain agricultural regions affects the sales of vegetables classified as traditional. We focused on the sales trends of traditional vegetables from the Noto region, one of the first designated sites of Globally Important Agricultural Heritage Systems (GIAHS). We compared the sales of recognized traditional vegetables to those of similar traditional vegetables from nearby areas and vegetables labeled with the same place names as the traditional vegetables but without elements of traditionality in branding. The study analyzed the sale and relevant trends of four categories of vegetable: Kaga vegetables, vegetables labeled “Kaga”, Noto vegetables, and vegetables labeled “Noto”. We further analyzed the trends by applying Convention Theory to understand the underpinning “orders of worth” in the purchase and sale of the items. Both Noto vegetables and place-labeled vegetables increased in overall sales since GIAHS registration in 2011. The recent increases in sales volume and number of items, however, were largely due to the production of lettuce, a crop from a vegetable factory. By applying Convention Theory, we identified that in the agriculture of the region, industrial farming impacted even the GIAHS registered site. Thus, careful collection and analysis of evidence is necessary to evaluate the effects of GIAHS registration and draft an action plan for further evidence-based policy making.
Research on Vehicle-Road Co-Location Method Oriented to Network Slicing Service and Traffic Video
Authors: Ma Zhi , Sun Songlin
Published: May 2021

The development of 5G network slicing technology, combined with the application scenarios of vehicle–road collaborative positioning, provides end-to-end, large-bandwidth, low-latency, and highly reliable flexible customized services for Internet of Vehicle (IoV) services in different business scenarios. Starting from the needs of the network in the business scenario oriented to co-location, we researched the application of 5G network slicing technology in the vehicle–road cooperative localization system. We considered scheduling 5G slice resources. Creating slices to ensure the safety of the system, provided an optimized solution for the application of the vehicle–road coordinated positioning system. On this basis, this paper proposes a vehicle–road coordinated combined positioning method based on Beidou. On the basis of Beidou positioning and track estimation, using the advantages of the volumetric Kalman model, a combined positioning algorithm based on CKF was established. In order to further improve the positioning accuracy, vehicle characteristics could be extracted based on the traffic monitoring video stream to optimize the service-oriented positioning system. Considering that the vehicles in the urban traffic system can theoretically only travel on the road, the plan can be further optimized based on the road network information. It was preliminarily verified by simulation that this research idea has improved the relative single positioning method.
Gravity Control-Based Data Augmentation Technique for Improving VR User Activity Recognition
Authors: Han Dongheun , Lee Chulwoo , Kang Hyeongyeop
Published: May 2021

The neural-network-based human activity recognition (HAR) technique is being increasingly used for activity recognition in virtual reality (VR) users. The major issue of a such technique is the collection large-scale training datasets which are key for deriving a robust recognition model. However, collecting large-scale data is a costly and time-consuming process. Furthermore, increasing the number of activities to be classified will require a much larger number of training datasets. Since training the model with a sparse dataset can only provide limited features to recognition models, it can cause problems such as overfitting and suboptimal results. In this paper, we present a data augmentation technique named gravity control-based augmentation (GCDA) to alleviate the sparse data problem by generating new training data based on the existing data. The benefits of the symmetrical structure of the data are that it increased the number of data while preserving the properties of the data. The core concept of GCDA is two-fold: (1) decomposing the acceleration data obtained from the inertial measurement unit (IMU) into zero-gravity acceleration and gravitational acceleration, and augmenting them separately, and (2) exploiting gravity as a directional feature and controlling it to augment training datasets. Through the comparative evaluations, we validated that the application of GCDA to training datasets showed a larger improvement in classification accuracy (96.39%) compared to the typical data augmentation methods (92.29%) applied and those that did not apply the augmentation method (85.21%).
Constraints on Newtonian Interplanetary Point-Mass Interactions in Multicomponent Systems from the Symmetry of Their Cycles
Authors: Hofmeister Anne M. , Criss Everett M.
Published: May 2021

Interplanetary interactions are the largest forces in our Solar System that disturb the planets from their elliptical orbits around the Sun, yet are weak (<10−3 Solar). Currently, these perturbations are computed in pairs using Hill’s model for steady-state, central forces between one circular and one elliptical ring of mass. However, forces between rings are not central. To represent interplanetary interactions, which are transient, time-dependent, and cyclical, we build upon Newton’s model of interacting point-mass pairs, focusing on circular orbits of the eight largest bodies. To probe general and evolutionary behavior, we present analytical and numerical models of the interplanetary forces and torques generated during the planetary interaction cycles. From symmetry, over a planetary interaction cycle, radial forces dominate while tangential forces average to zero. Our calculations show that orbital perturbations require millennia to quantify, but observations are only over ~165 years. Furthermore, these observations are compromised because they are predominantly made from Earth, whose geocenter occupies a complex, non-Keplerian orbit. Eccentricity and inclination data are reliable and suggest that interplanetary interactions have drawn orbital planes together while elongating the orbits of the two smallest planets. This finding is consistent with conservation principles governing the eight planets, which formed as a system and evolve as a system.
The Role of Non-Structural Protein NSs in the Pathogenesis of Severe Fever with Thrombocytopenia Syndrome
Authors: Khalil Jumana , Kato Hiroki , Fujita Takashi
Published: May 2021

Viral non-structural proteins, such as NSs of the newly emerging severe fever with thrombocytopenia syndrome virus, are well established virulence factors, mediating viral pathogenesis and disease progression through various mechanisms. NSs has been described as a potent interferon antagonist and NF-κB agonist, two divergent signaling pathways in many immune responses upon a viral encounter. In this review, we highlight the many mechanisms used by NSs on the host that promote viral replication and hyper-inflammation. Understanding these host-pathogen interactions is crucial for antiviral therapy development.
Vaccines in Children with Inflammatory Bowel Disease: Brief Review

Published: May 2021

Incidence of inflammatory bowel diseases (IBDs), including Crohn’s disease (CD) and ulcerative colitis (UC), is increasing worldwide. Children with IBDs have a dysfunctional immune system and they are frequently treated with immunomodulating drugs and biological therapy, which significantly impair immune system functions and lead to an increased risk of infections. Vaccines are essential to prevent at least part of these infections and this explains why strict compliance to the immunization guidelines specifically prepared for IBD patients is strongly recommended. However, several factors might lead to insufficient immunization. In this paper, present knowledge on the use of vaccines in children with IBDs is discussed. Literature review showed that despite a lack of detailed quantification of the risk of infections in children with IBDs, these children might have infections more frequently than age-matched healthy subjects, and at least in some cases, these infections might be even more severe. Fortunately, most of these infections could be prevented when recommended schedules of immunization are carefully followed. Vaccines given to children with IBDs generally have adequate immunogenicity and safety. Attention must be paid to live attenuated vaccines that can be administered only to children without or with mild immune system function impairment. Vaccination of their caregivers is also recommended. Unfortunately, compliance to these recommendations is generally low and multidisciplinary educational programs to improve vaccination coverage must be planned, in order to protect children with IBD from vaccine-preventable diseases.

Published: May 2021

Temporal and spatial water quality data are essential to evaluate human health risks. Understanding the interlinking variations between water quality and socio-economic development is the key for integrated pollution management. In this study, we applied several multivariate approaches, including trend analysis, cluster analysis, and principal component analysis, to a 15-year dataset of water quality monitoring (1999 to 2013) in the Thi Vai estuary, Southern Vietnam. We discovered a rapid improvement for most of the considered water quality parameters (e.g., DO, NH4, and BOD) by step trend analysis, after the pollution abatement in 2008. Nevertheless, the nitrate concentration increased significantly at the upper and middle parts and decreased at the lower part of the estuary. Principal component (PC) analysis indicates that nowadays the water quality of the Thi Vai is influenced by point and diffuse pollution. The first PC represents soil erosion and stormwater loads in the catchment (TSS, PO4, and Fetotal); the second PC (DO, NO2, and NO3) determines the influence of DO on nitrification and denitrification; and the third PC (pH and NH4) determines point source pollution and dilution by seawater. Therefore, this study demonstrated the need for stricter pollution abatement strategies to restore and to manage the water quality of the Thi Vai Estuary.

Published: May 2021

The present study aimed to investigate major volatile compounds, organic acid, phenolic and mineral contents, and antiradical and antimicrobial properties of home-made apple/grape vinegar. Grape vinegar showed higher total acidity, organic acid content, total phenolic content (TPC), antiradical activity and lower minimum inhibitory concentration (MIC) values compared to apple vinegar. While acetic and tartaric acids were the most abundant organic acids in grape vinegar, acetic and succinic acids were the most abundant organic acids in apple vinegar. The most abundant phenolic compound was gallic acid in both grape and apple vinegar. A total of 18 and 9 volatile compounds were determined in grape vinegar samples and apple vinegar samples, respectively. The most abundant volatile compounds were acetic acid and acetoin in grape vinegar, acetic acid, ethyl acetate and 2,4,5-trimethyl-1,3-dioxolane in apple vinegar. K, Ca and Na were common minerals in both vinegar and more in the grape vinegar compared to apple vinegar. Although MIC value for grape vinegar was at 6.25% with minimum bactericidal concentration (MBC) values ranged from 6.25% to 12.50%, MIC value for apple vinegar was at 12.50% with MBC values ranged from 12.50% to 25.00% for all test bacteria. The antiradical and antibacterial activities of the vinegar samples were correlated with their TPC and organic acid contents.

Published: May 2021

The purpose of the article is to present the results of a pilot study of the problems of disabled convicts that arise during their period of adaptation to prison conditions. The author seeks to explain in the article what impedes the effective adaptation to prison conditions of such a specific category of prisoners as the disabled; what difficulties they face, what their attitude to the environment and to other people is, what their wishes and motives are. What was used as a research methodology was a questionnaire which had been developed by the author. The results of the research allowed us to analyse the difficulties that the convicts of this category face at the initial stage of serving their sentence in the correctional facility and to compare the data obtained with the results of theoretical research. The content of the article allows solving two main tasks – theoretical one, to formulate criteria of adaptation of disabled convicts to conditions of imprisonment; practical one, to outline ways to improve pedagogic support of the process of their adaptation.

Authors: Nemov Robert Semenovich , Kanishcheva Anastasia Sergeevna
Published: May 2021

The theoretical and experimental (empirical) studies of the motive and motivation for achieving success, which began in the second half of the twentieth century, have so far practically not dealt with school educational activities and were mainly related to different types of professional activities of people. Successful learning in school is at the heart of all other activities that a person enters into after graduation from high school. In this regard, it becomes necessary to form and develop motivation for achieving success in children during that period of life when they are still studying at school. For this, it is necessary to solve a number of theoretical and methodological issues related to the formation and development of such motivation in schoolchildren. These questions relate to the creation of a theoretical model of motivation for achieving success in educational activities, determining its main components, developing methods for their diagnosis, methods of organising and conducting training aimed at developing the motivation and motivation for achieving success in schoolchildren. All these questions are posed and solved in this study.

Published: May 2021

We systematically study geometries and band structures of two-dimensional group-V bilayer materials, i.e. phosphorene, arsenene and antimonene. Among the four stacking structures (AA, AB, AC, and AD), the AB stacking structures are found to be the largest band gaps and to be the most energetically stable. We find novel band structures on the whole Brillouin zone edges: four bands have close energies and two of the four bands have the same energy in many cases. We analyze the characteristic features of the band structures based on the group theory and clarify that the features depend on the space group of each stacking structure. We also find that the band splits due to the interlayer interaction is very small and this interaction becomes large as atoms become heavy.

Published: May 2021

We demonstrated room-temperature pulsed-operations of GaN-based blue edge-emitting laser diodes (LDs) with both the top and bottom AlInN cladding layers by using GaN tunnel junctions (TJs) grown by metalorganic vapor phase epitaxy. The LDs with a 1.2 mm cavity length and a 15 μm ridge width were fabricated. We obtained a low threshold current density of 0.9 kA cm−2 with facet coating. We found that while an optical absorption loss in the waveguiding layer was reduced with a low Mg concentration (3 × 1018 cm−3), that in a highly doped TJ could be an obstacle to obtain further improvements of the laser characteristics.

Formas lógicas y formas de vida
Authors: Reinoso Guadalupe
Published: May 2021

En la conferencia “Las lógicas y las cosas” (2014), Alberto Moretti sostiene que los enfoques que se centran en el fenómeno de la interpretación para dar cuenta del problema del significado adolecen de un problema, a saber, no admiten las condiciones trascendentales que posibilitan la significatividad. Así, en el contexto de la interpretación, el hecho de distinguir a otros como hablantes es la posibilidad de distinguir a otros como objetos relacionados en el mundo (no lingüístico). Esta distinción es posible porque los principios lógicos específicos exponen la estructura básica para el discurso y el pensamiento pero también, la estructura elemental del mundo o realidad (Moretti, 2016, p. 1). En otras palabras, los principios lógicos que estructuran nuestro lenguaje son también principios de las cosas (cf. Moretti, 2014: 1:23:14). Este argumento puede ser considerado un argumento trascendental por establecer, a través del señalamiento de ciertas condiciones necesarias, la íntima conexión lenguaje-mundo que da cuenta de la significatividad, y por insinuarse como una respuesta al problema del mundo externo (cf. Moretti, 2014: 1:39:13). Me propongo discutir el alcance de este argumento a partir de la idea de la autonomía del lenguaje que Wittgenstein desarrolla en Sobre la Certeza, la cual conlleva una estrategia disolutoria alternativa frente al desafío escéptico. Para dar cuenta de dicha estrategia, me centraré en la distinción entre proposiciones lógicas y empíricas. También analizaré la distinción mostrar-decir que, en su relación con la noción de “formas de vida”, permite iluminar aspectos de su enfoque praxiológico sobre el lenguaje. Así, defenderé un enfoque que no omite, sino que rechaza, la posibilidad de un punto de vista externo (trascendental), tanto para dar cuenta del lenguaje como para responder al escéptico.
Lógica, justificación y normatividad
Authors: Buacar Natalia
Published: May 2021

Alberto Moretti en “La lógica y la trama de las cosas” presenta y defiende una concepción de la lógica según la cual existen principios lógicos que estructuran el lenguaje y, consecuentemente, el mundo. Este modo de entender la lógica ofrece una respuesta al problema de su normatividad, al tiempo que disuelve el problema de su justificación. En este trabajo, analizo críticamente esta mirada acerca de la lógica y propongo una concepción alternativa que permite vindicar la legitimidad de ambos problemas y darles una respuesta satisfactoria.
Knowledge-based engineering in the context of railway design by integrating BIM, BPMN, DMN and the methodology for knowledge-based engineering applications (MOKA)
Authors: Häußler Marco , Borrmann André
Published: May 2021

Designing railway infrastructure is a knowledge-intensive task. Although there are a number of mature design authoring systems available, their support for dynamically incorporating domain-specific engineering knowledge is very limited. At the same time, a standardized digital representation of railway engineering knowledge (such as building codes and best practice) does not exists. To overcome this deficiency, this paper proposes the use of Knowledge Based Engineering (KBE) to automate routine design tasks by considering multiple knowledge sources. In this scenario, KBE is used to support a Railway design authoring system. To ensure maximum transparency in the design of the developed KBE application, graphical ‘Business Process Model and Notation’ (BPMN) has been used in combination with ‘Decision Model and Notation’ (DMN) to formalize the underlying engineering knowledge. The KBE application has been developed according to the Methodology for Knowledge-Based Engineering Applications (MOKA). An evaluation of the BPMN/DMN approach shows that it meets up to 58% of the acceptance criteria found in the literature. In addition, BPMN and DMN can already be used in the early capture phase of MOKA and its workflows can be developed into an executable KBE application in the subsequent phases. The results of the test example discussed here show that time savings of up to 97.5% can be achieved in the execution of the KBE application.

Five cultivars were studied: Koralova, Velykoplidna, Rubinova, Ukrainochka, and Bahriaana. In addition, 21 elite hybrid forms, which had been planted in plots of 4 m x1.5 m in 1998, were investigated. The number of recorded plants per plot was 15 in 3 replications. Measurements and monitoring were performed according to conventional methods. Multi-year breeding resulted in the following cranberry tree cultivars: Koralova, Velykoplidna, Rubinova, Ukrainochka, and Bahriana. Pomological characteristics of the cultivars are given for basic economic and biological features under the conditions of the forest-steppe of Ukraine. The yield capacity is the main criterion in economic evaluation of V. opulus. It to a large extent depends on characteristics of a cultivar, soil and climatic factors, and farming techniques. The fruit size and palatability are major components of the performance determining the fruit quality. Large and uniform berries are more attractive both as fresh and as frozen products. In 2015-2019, the V. opulus yield ranged 6.52 to 9.37 kg per bush and 10.9 to 15.6 tons per hectare. The average berry weight was 0.8 - 1.25 g. Cultivar Bahriana and hybrid form Ch-19500 were the most productive: 9.37 kg and 9.19 kg per bush, respectively. Velykoplidna, Rubinova and Bahriana were distinguished due to the average berry weight: 1.25 g, 1.2 g and 1.2 g, respectively. We built up a working collection of V. opulus accessions by yield capacity and quality. The collection comprises 20 cultivars. All the cultivars are of local origin. The collection is formed by the following traits: yield level, berry size, berry shape, berry after colour, berry hardness, palatability, and the berry number per corymb.
Conclusions. The 2015-2019 studies showed that the highest yields were obtained from Bahriana (15.6 t/ha), elite hybrid form Ch-19500 (15.3 t/ha) and elite hybrid form P-19503 (15 t/ha); the highest fruit weight was recorded in Velykoplidna (1.25 g), Rubinova (1.2 g), Bahriana (1.2 g), Ukrainochka (1.15 g), and elite hybrid form P-19503 (1.16 g); the best palatability scores were intrinsic to Koralova (8.5 points), Rubinova (8.5), Ukrainochka (8.3), Bahriana (8.3), elite hybrid form K-19501 (8.3).

In this paper, we will consider the challenges facing the regulation of public relations related to the system of using artificial intelligence. At the moment, there is no legal regulation in this area, or it is fragmentary and unsystematic, so in my work I will mostly assess the consequences of using artificial intelligence systems from the standpoint of ethical, moral and other informal norms. Is there a chance for humanity to avoid the scenario of an Orwellian dystopia?

Nouveautés dans le syndrome des anticorps antiphospholipides en réanimation

Le syndrome des anticorps antiphospholipides (SAPL) est une maladie auto-immune systémique définie par la survenue d’événements thrombotiques ou obstétricaux associés à la positivité persistante (au moins 12 semaines) d’anticorps antiphospholipides (aPL). Le SAPL peut conduire les malades en réanimation sous la forme d’un orage thrombotique, appelé « syndrome catastrophique des anticorps antiphospholipides » ou CAPS. Il a été défini comme la survenue en moins de sept jours d'au moins trois atteintes d'organes, de tissus ou de systèmes, liées à des thromboses microvasculaires prouvées chez des malades ayant des titres d'anticorps antiphospholipides élevés. Il a fait l’objet d’un consensus international avec élaboration de critères internationaux de classification. Les thromboses peuvent intéresser tous les vaisseaux et tous les organes. Lorsqu’elles sont microvasculaires, elles réalisent la forme typique du CAPS et ne peuvent être diagnostiquées que par la biopsie de l’organe atteint. La thrombopénie est le maitre signe biologique du syndrome. Elle est quasi constante, parfois profonde et souvent associée à une anémie sans réaliser fréquemment un syndrome de microangiopathie thrombotique. Il s'agit d'une maladie très rare, rendant quasiment impossible les essais cliniques randomisés. L’anticoagulation est le seul traitement à avoir été associé à une diminution de la mortalité dans plusieurs cohortes. Une triple thérapie associant une anticoagulation, une corticothérapie à forte dose et soit des échanges plasmatiques soit des immunoglobulines intraveineuses a été retenue comme le traitement de référence des malades graves. Le pronostic du CAPS reste sévère avec une mortalité à un an des patients admis en réanimation de l’ordre de 34 %. Compte tenu de la rareté et de la sévérité de ce syndrome, une prise en charge diagnostique et thérapeutique collégiale entre médecins intensivistes et internistes est indispensable.

We examine scalar differential equations with a general piecewise constant argument (DEPCAG). It is shown that the argument deviation generates, under certain conditions, oscillations of the solutions, which is an impossible phenomenon for the corresponding equation without the argument deviations. Criteria for existence of periodic solutions of such equations are discussed.
Career Opportunity for Ghanaian Youth: An Evaluation of Jewellery Subject under Visual Art Programme in Senior High Schools in Ghana
Authors: Mohammed Kwaku Baidoo
Published: May 2021

The purpose of the study was to evaluate the Jewellery subject in Senior High Schools in Ghana to ascertain
the career opportunity in jewellery for Ghanaian youth. The study adopted the Mixed Methods Research approach with descriptive and document analysis as the research method used. The findings of the study show that jewellery students are not able to practise as jewellers after their studies, because the content of the jewellery subjects and its associated exercises does not correspond to the skills one is required to become a jeweller. Coupled with the fact that the teachers who teach the jewellery are mostly not professional jewellers, which therefore limit the kind of practical jewellery that they can teach the students. Although the motivating factor for introducing jewellery is good, however, the rhetorics of the government that she wants students to acquire skills in jewellery making does not support the reality on the ground.
