Published: September 2022

Known for excellent convenience and abundant facilities, smart cities offer CCTV, delivery robots, security robots, and so on to its residents. Along with the collaboration of IoT (Internet Of Things), the innovation of smart city has gained immense attraction at present. Besides, the risks and challenging in the field of telecommunication still persists as the implemented wireless networks results in traffic and anomaly behaviour. Such issues become critical in case of large-scale infrastructure networks like WSN’s. As such circumstances, to perform efficient health and environment monitoring, the need for a next generation networked system raises. As the traditional anomaly detection schemes doesn’t work out for delay-sensitive environments due to increased latency, we propose a scalable, hybrid spatiotemporal anomaly detection approach that can effectively detect potential anomalies in the network. With the use of real-time stream processing, and other methodologies like Software-Defined Networking (SDN), a Fog Computing-based 5G low-power Wide Area Network (LPWAN) solution is developed and tested on a Antwerp’s City of Things testbed. The proposed approach is found to be beneficial when deployed in a real network environment with nearly 1800 sensor nodes.

Inhalt Die steigende Komplexität von technischen Systemen ist bei der Entwicklung neuer Produkte eine große Herausforderung. Zur Unterstützung des Produktentwicklers bei der Bewältigung dieser Herausforderung werden computergestützte Methoden eingesetzt, um frühzeitig das Produktverhalten abschätzen zu können. Dabei ist der Einsatz von CAE-Methoden einzelner Domänen nicht ausreichend, um Wechselwirkungen zwischen bspw. der Elektrotechnik und dem Maschinenbau abzubilden. Daher bedarf es einer Kopplung von Simulationsmethoden, die die verschiedenen Domänen miteinander verknüpft. Mit dem dadurch bedingten erhöhten Modellierungsaufwand gehen jedoch Entwicklungsrisiken einher, die bewertet werden müssen. Mithilfe des vorgestellten Modellierungsansatzes wird diese Bewertung des Entwicklungsrisikos gekoppelter CAE-Methoden beherrschbar gemacht, wodurch eine strategische Planung der Entwicklungsaktivitäten ermöglicht wird.

Studies of resolved stellar populations in the Milky Way and nearby galaxies reveal an amazingly detailed and clear picture of galaxy evolution. Within the Local Group, the ability to probe the stellar populations of small and large galaxies opens up the possibility of exploring key questions such as the nature of dark matter, the detailed formation history of different galaxy components, and the role of accretion in galactic formation. Upcoming wide-field surveys promise to extend this ability to all galaxies within 10 Mpc, drastically increasing our capability to decipher galaxy evolution and enabling statistical studies of galaxies’ stellar populations. To facilitate the optimum use of these upcoming capabilities, we develop a simple formalism to predict the density of resolved stars for an observation of a stellar population at fixed surface brightness and population parameters. We provide an interface to calculate all quantities of interest to this formalism via a public release of the code walter. This code enables calculation of (i) the expected number density of detected stars; (ii) the exposure time needed to reach certain population features, such as the horizontal branch; and (iii) an estimate of the crowding limit, among other features. We provide a limited test of the code and formalism of the paper against existing resolved star observations. These calculations will be very useful for planning surveys with NASA’s upcoming Nancy Grace Roman Space Telescope (Roman, formerly WFIRST), which we use for example calculations throughout this work.

Published: September 2022

An impact experiment was performed with a target of relevance to the upcoming DART impact. In this experiment, a collection of stones that is similar to a rubble pile was the target, though it was necessary to hold the stones in place (in this case with cement) since the target was hung vertically to perform the experiment. The stones–cement target has a higher density and a lower porosity than expected for Dimorphos, with the density being 2.92 g cm−3. A 3 cm diameter aluminum sphere was launched at a speed of 5.44 km s−1, which is similar to the anticipated 6.1 km s−1 impact speed of DART. The stones–concrete target was completely disassembled by the impact. The target was mounted on a pendulum. The swing of the pendulum was measured and from it the momentum enhancement

AIM: The focus of this research was to see how silica nanoparticles changed veneering porcelain over a zirconia core affected flexure strength, shear bond strength, and color.

METHODS: A total number of 30 zirconia core veneer samples were constructed and classified according to silica nanoparticles modification of veneering porcelain into two groups: Group 1 (control group) veneering porcelain without any modification (n = 15) and Group 2 (modified group) veneering porcelain modified by silica nanoparticles (n = 15). Silica nanoparticles were added to the veneering porcelain powder at a rate of 5% by weight. Silica nanoparticles powder and veneering porcelain powder were manually crushed for about 10 min using a pestle and mortar then the mixed powder was combined with the porcelain moldings liquid to make a paste. After thermal cycling, each group was examined for flexural strength, shear bond strength, and color measurement (n = 5). Universal testing equipment was used to determine flexural and shear bond strength. The color shift was measured using a spectrophotometer.

RESULTS: Flexural strength levels in the modified group (280.9 ± 29.85 Mpa) were substantially higher than in the control group (431.78 ± 22.73 Mpa). Shear bond strength values in the modified group (34.31 ± 5.6) were significantly higher than in the control group (26.97 ± 4.03). Color change was within the clinical acceptable range (1.71 ± 0.32).

CONCLUSIONS: The addition of silica nanoparticles to veneering porcelain improved the flexural and shear bond strength, as well as, color change was within the clinical acceptable limits.

Introduction: Anaplastic astrocytoma (AA) is a rare brain neoplasm that belongs to grade III gliomas according to the World Health Organization (WHO) classification. It represents only 6% of all Central Nervous System (CNS) malignancies, yet; it is associated with low survival rates. We aim to identify the survival rate after tumor resection from 10 years of experience. We also wish to determine the effect of pre and post-operative tumor volumes on the overall survival (OS).
Methods: We retrospectively reviewed the records of patients with anaplastic astrocytoma who had surgery between January 2010 and January 2020. Based on Magnetic resonance imaging (MRI) results obtained < 72 hours after surgery, the Extent of Resection (EOR) was calculated by pre-op volume – post-op volume/pre-op volume*100% and classified into five categories. 1)>99% - Gross total resection (GTR) 2) 91-99% as Near-total resection (NTR) 3) 70-90% as Sub-total resection (STR) 4) <70% as Partial resection (PR) and 5) Biopsy. A multivariate proportional hazards regression analysis assessed the independent association of EOR and subsequent OS.
Results: 34 patients were finally included in our analysis. The median survival time for all patients was 24.4 months, whereas the histopathological type of AA like IDH mutant was 32 months, and IDH wild type was 16.1 months as OS time. We stratified the observed survival durations for the patients according to the EOR into 5 different classes. We found that the EOR didn't affect the overall median survival. Regression analysis showed no statistically significant association between the pre or post-operative tumor volume and the OS time.
Conclusion: Anaplastic astrocytoma is a tumor that carries a poor diagnosis. Gross total resection is essential to increase patients expected survival time. Unfortunately, the extent of tumor resection and tumor volume isn't correlated with the survival time for patients.

BACKGROUND: Many studies have found that assessing COVID-19 preventive behaviors using the health belief model (HBM) to understand both motives and fears is critical to better controlling the disease.

AIM: The aim of the study was to assess the perceptions of social distancing as a preventive measure during the COVID-19 pandemic using the HBM among a sample of the Egyptian population.

METHODS: An exploratory cross-sectional study was conducted using an online survey distributed through one of Egypt’s most popular social media platforms. Four hundred and seventy people responded to the survey. The survey constructed of two sections; the first section for sociodemographic data and Section 2 was for HBM constructs of self-efficacy, perceived susceptibility, and severity to COVID-19 prevention benefits and barriers.

RESULTS: More than half of the participants (59.8%) were in the age range of 20–29, with an average age of 29.0 ± 6.4 years. Two hundred ninety-seven participants (63.2%) were females; 60.2% lived in the canal region; 57.9% were single; and 70% had university degrees. There were statistically significant differences regarding gender; females’ perceived higher scores in almost all model constructs (benefits, susceptibility, severity, self-efficacy, and total score). Many statistically significant differences were observed; those who were older than 30 years had higher scores in barriers, benefits, self-efficacy, and total score than younger ones. Similarly, married participants reported higher scores in barriers, benefits, self-efficacy, and total score than younger ones. Postgraduate education perceived higher scores than university in benefits, susceptibility, self-efficacy, and total score.

CONCLUSION: In the present study, the majority of respondents had relatively high perceived benefits, severity, and self-efficacy, with the lower perceived self-COVID-19 susceptibility but higher for family members. Females perceived higher scores in almost all model constructs (benefits, susceptibility, severity, self-efficacy, and total score).
L’IAE : un monde social à la reconquête du pouvoir d’agir au sein des politiques publiques d’insertion
Authors: Balzani Bernard
Published: September 2022

Depuis près de quinze ans, nous travaillons à partir de l’hypothèse que l’insertion par l’activité économique traverse une période historique de transformation tant sur le plan des représentations (instrumentalisation par les pouvoirs publics, incompréhension de l’opinion publique, déni de reconnaissance chez les responsables) que sur celui de l’efficacité des outils mis en œuvre dans ces organisations. Ces processus produisent une « crise » de valeurs chez les acteurs engagés dans ce mouvement de « décomposition et de recomposition ».
Le PLIE, un dispositif collaboratif des IAE
Authors: Berson Marine
Published: September 2022

L’aspect psychosocial des difficultés face à l’accès à une activité professionnelle durable induit la nécessité de proposer des accompagnements au cas par cas dans le champ de l’insertion et de l’emploi. L’action d’accompagnement psychologique temporaire s’adresse à des personnes très éloignées de l’emploi et précarisées. En tant que psychologue clinicienne prestatrice du plie , certains de ces suivis laissent entrevoir, par les mouvements affectifs parti- culiers qui émergent au fil des rencontres, tout le désespoir et la douleur que peuvent produire l’absence de travail et l’éloignement du champ socioprofessionnel.
De la contrainte au plaisir de participation à la prévention des risques
Authors: Trézéguet Muriel
Published: September 2022

Depuis 2001, l’évaluation des risques professionnels est rendue obligatoire dans toute organisation du travail. Cette évaluation représente un moment important dans la démarche de prévention car elle est le point de départ pour définir les actions de prévention appropriées, couvrant les dimensions techniques, humaines et organisationnelles. L’enjeu est de pouvoir associer l’ensemble des salariés de l’organisation afin de les rendre acteurs de leur propre prévention. L’utilisation de l’art peut faciliter ce travail.
L’ISIC, pour redonner du sens au travail social
Authors: Kowalczuk Sylvie
Published: September 2022

L’accompagnement social est bousculé par la dureté des situations, les problématiques extrêmes, les précarités multiples, avec en toile de fond des injonctions, procédures et dispositifs allant parfois à l’encontre du travail social dans son acceptation originelle : « Il participe au développement des capacités des personnes à agir pour elles-mêmes et dans leur environnement. » L’ isic est le lieu qui réunit tous ces principes qui donnent corps au travail social. Et pourtant, c’est une pratique encore trop peu utilisée.

The current descriptive qualitative study explored the perceived impact of the coronavirus disease 2019 pandemic on sleep disturbances and nighttime agitation; the reported use of antipsychotics and other sedating medications; and the overall well-being of older adults with Alzheimer's disease and related dementias (ADRD) and their caregivers. One investigator conducted in-depth, phone interviews with caregivers of nursing home residents with ADRD (four family caregivers [FCs], three nurse practitioners [NPs]) and seven FCs of older adults with ADRD who lived with them at home. Caregivers described multiple sleep disturbances. Nighttime agitation symptoms were perceived to continue or worsen, and sedating medications and nonpharmacological interventions were required. Adverse impacts on reported well-being were significant, and impacts were grouped into emotional, social, and physical themes. Caregivers said, “Please don't forget us,” and requested telehealth support for those at home and technology and human resources for nursing homes to reduce adverse impacts. [

Authors: Frechman Erica , Buck Harleah G. , Dietrich Mary S. , Maxwell Cathy A.
Published: September 2022

There is a gap in understanding adults' readiness to plan for adaptions across the aging trajectory. The purpose of the current psychometric project was to develop and test the Planning for Aging and Frailty Questionnaire. Clinical experience and extant literature formed the basis for creating items measuring planning for aging. Content validity was established with gerontology and health service research experts. Face validity testing was conducted through two cognitive interviewing and debriefing sessions at a senior center. All survey questions resulted in a content validity index ≥0.80 from experts. Face validity testing involved successful completion of the survey by 12 adults followed by cognitive interviewing/debriefing, resulting in minor changes. The 21-item Planning for Aging and Frailty Questionnaire demonstrates good initial validity and can be used to measure readiness in planning for aging and personal experiences and experiences with others. Further testing with additional usage is warranted. [
