Updates on Paget’s Disease of Bone
Authors: Choi Yong Jun , Sohn Young Bae , Chung Yoon-Sok
Published: October 2022

Paget’s disease of the bone is a prevalent bone disease characterized by disorganized bone remodeling; however, it is comparatively uncommon in East Asian countries, including China, Japan, and Korea. The exact cause still remains unknown. In genetically susceptible individuals, environmental triggers such as paramyxoviral infections are likely to cause the disease. Increased osteoclast activity results in increased bone resorption, which attracts osteoblasts and generates new bone matrix. Fast bone resorption and formation lead to the development of disorganized bone tissue. Increasing serum alkaline phosphatase or unique radiographic lesions may serve as the diagnostic indicators. Common symptoms include bone pain, bowing of the long bones, an enlarged skull, and hearing loss. The diagnosis is frequently confirmed by radiographic and nuclear scintigraphy of the bone. Further, bisphosphonates such as zoledronic acid and pamidronate are effective for its treatment. Moreover, biochemical monitoring is superior to the symptoms as a recurrence indicator. This article discusses the updates of Paget’s disease of bone with a clinical case.
Update on Preoperative Parathyroid Localization in Primary Hyperparathyroidism
Authors: Park Hye-Sun , Hong Namki , Jeong Jong Ju , Yun Mijin , Rhee Yumie
Published: October 2022

Parathyroidectomy is the treatment of choice for primary hyperparathyroidism when the clinical criteria are met. Although bilateral neck exploration is traditionally the standard method for surgery, minimally invasive parathyroidectomy (MIP), or focused parathyroidectomy, has been widely accepted with comparable curative outcomes. For successful MIP, accurate preoperative localization of parathyroid lesions is essential. However, no consensus exists on the optimal approach for localization. Currently, ultrasonography and technetium-99m-sestamibi–single photon emission computed tomography/computed tomography are widely accepted in most cases. However, exact localization cannot always be achieved, especially in cases with multiglandular disease, ectopic glands, recurrent disease, and normocalcemic primary hyperparathyroidism. Therefore, new modalities for preoperative localization have been developed and evaluated. Positron emission tomography/computed tomography and parathyroid venous sampling have demonstrated improvements in sensitivity and accuracy. Both anatomical and functional information can be obtained by combining these methods. As each approach has its advantages and disadvantages, the localization study should be deliberately chosen based on each patient’s clinical profile, costs, radiation exposure, and the availability of experienced experts. In this review, we summarize various methods for the localization of hyperfunctioning parathyroid tissues in primary hyperparathyroidism.
Pandemonium of diseases after floods – An emerging major health issue in Pakistan
Authors: Ujjan Ikram Din
Published: October 2022

Floods and heavy rain bring another disaster of diseases and pose a huge burden on the health care system. Pakistan is currently facing a major natural disaster of this decade, where Sindh and Baluchistan are badly affected. Millions of people are homeless and live in camps, shelter homes, or tent cities. The diseases that emerge immediately after floods include gastroenteritis with diarrhoea and vomiting, followed by vector-borne diseases (i.e. malaria and dengue fever) influenced by the growth of mosquitoes in the stagnant water. Due to unhygienic conditions and overcrowded camps, skin diseases emerge later. Altogether this situation causes major burden on the already weakened health care system, which is devastated due to rain and even destroyed in some places. Thus proper planning and preventive measures need to be taken on an urgent basis.

Published: October 2022

This study aimed to evaluate histopathological changes in the placentas of mothers who had contracted COVID-19 during pregnancy. This prospective study involved the histopathological assessment of two groups of placentas submitted for evaluation to the Department of Histopathology at Khoula Hospital, Oman. The first group consisted of 48 placentas derived from COVID-19-positive pregnant women delivered at the centre between March 2020 and March 2021. The control group consisted of an additional 48 placentas derived from asymptomatic mothers who were not tested for COVID-19 but were assumed to be negative. All placentas underwent gross and microscopic histopathologic examination. Placental lesions were classified according to the Amsterdam system. There was a significantly higher frequency of fibrin thrombi at the terminal villi in placentas derived from the COVID-19-positive group compared to the control group (72.9% versus 0%; p-value = 0.001). Also, villous hypoperfusion was significantly more common in COVID-19-positive placentas than in controls (16.7% versus 0%; p-value = 0.006). However, no significant differences between the two groups were noted with regards to the frequency of other histopathologic features, including decidual vasculopathy, chorioamnionitis, funisitis, intervillositis, perivillous fibrin deposition, and infarction.

Published: October 2022

This study was conducted to determine the clinico-epidemiological evaluation of chronic folliculitis of the leg in the southern Indian population. This was a prospective observational study, undertaken over a period of two years. All patients attending the outpatient department Southern Indian tertiary care hospital's Dermatology Department (M.K.C.G.Medical College & Hospital, Odisha) were recruited. A total of 100 patients were enrolled, aged between 12 to 70 years with a M: F ratio of 10.1: 1. Eighty per cent of the population in the study were rural, and 20% belonged to the urban area. Clinical characteristics and demographic data of the patients were collected in a pre-designed proforma. Those patients who had pustules on the leg underwent pus culture and sensitivity test. Majority of the patients presented with papules and pustules (96%cases) and bilateral symmetrical leg involvement (98% cases). Pruritus was the most common clinical presentation ( 90% cases). Staphylococcus was isolated in the majority of cases (80%) and was sensitive to Amikacin (73%), Linezolid (70%), vancomycin (68%), and Gentamycin (65%). Chronic folliculitis of the leg is mainly a disease of young adult males of low socioeconomic status. Avoiding aggravating factors and cautious use of sensitive antibiotics may achieve treatment goals and decrease recurrence.

Published: October 2022

COVID-19 pandemic has brought a paradigm shift in education with a trend of online learning and even schooling. During complete lockdown period schools were shifted to smartphones and computers. This study aimed to explore the pattern of smartphone use before and after the COVID-19 pandemic and the health issues of school-going children in post-COVID-19 period. There was a significant rise in the timings of mobile phone use from 2 hours to 7 hours per day. A total of 90% of student’s mothers reported behavioral change where lack of socializing was the most commonly reported change. Irritation of eyes and dryness were the most commonly reported ocular disorders.  The rise of mobile phones has brought several behavioral and ocular disorders due to long hours of use. There is a need to confirm health-related issues of smartphone use in large prospective studies and develop preventive strategies.

First Millimeter Flares Detected from ϵ Eridani with the Atacama Large Millimeter/submillimeter Array
Authors: Burton Kiana , MacGregor Meredith A. , Osten Rachel A.
Published: October 2022

We report the detection of three large millimeter flaring events from the nearby Sun-like, ϵ Eridani, found in archival Atacama Large Millimeter/submillimeter Array (ALMA) 12 m and Atacama Compact Array observations at 1.33 mm taken from 2015 January 17 to 18 and 2016 October 24 to November 23, respectively. This is the first time that flares have been detected from a Sun-like star at millimeter wavelengths. The largest flare among our data was detected in the ALMA observations on 2015 January 17 from 20:09:10.4–21:02:49.3 UT with a peak flux density of 28 ± 7 mJy and a duration of 9 s. The peak brightness of the largest flare is 3.4 ± 0.9 × 1014 erg s−1 Hz−1, a factor of >50× times brighter than the star’s quiescent luminosity and >10× brighter than solar flares observed at comparable wavelengths. We find changes in the spectral index (F
ν
∝ ν

α
) at the flare peak, with α = 1.81 ± 1.94 and a lower limit on the fractional linear polarization ∣Q/I∣ = 0.08 ± 0.12. This positive spectral index is more similar to millimeter solar flares, differing from M-dwarf flares also detected at millimeter wavelengths that exhibit steeply negative spectral indices.

In the search for extraterrestrial life, biosignatures (e.g., organic molecules) play an important role, of which lipids are one considerable class. If detected, these molecules can be strong indicators of the presence of life, past or present, as they are ubiquitous in life on Earth. However, their detection is challenging, depending on, e.g., instrument performance, as well as the selected site. In this contribution, we demonstrate that, using laser desorption ionization mass spectrometry, detection of lipids is feasible. Using our space prototype instrument designed and built in-house, six representative lipids were successfully detected: cholecalciferol, phylloquinone, menadione, 17α-ethynylestradiol, α-tocopherol, and retinol, both as pure substances and as mixtures additionally containing amino acids or polycyclic aromatic hydrocarbons. Observed limits of detection for lipids already meet the requirements stated in the Enceladus Orbilander mission concept. The current performance of our LDI-MS system allows for the simultaneous identification of lipids, amino acids, and polycyclic aromatic hydrocarbons, using a single instrument. We therefore believe that the LDI-MS system is a promising candidate for future space exploration missions devoted to life detection.

Cryptic biodiversity of tropical hesperiid caterpillar-attacking parasitoid wasps: three new species of Creagrura Townes (Hymenoptera, Ichneumonidae, Cremastinae) from Costa Rica and Perú
Authors: Sääksjärvi Ilari , Kaunisto Kari , Sharkey Michael , Stedenfeld Shelby , Smith M. Alex , Hallwachs Winnie , Janzen Daniel
Published: October 2022

We describe three new species of the previously monotypic genus Creagrura Townes from Central and South America: C. alejandromasisi sp. n. and C. rogerblancoi sp. n. from Costa Rica and C. allpahuaya sp. n. from Peru, all of which emphasise the unknown parasitoid insect diversity yet to be revealed in the tropics.

Host relationships of the two Costa Rican species are described in detail. In addition, it is inferred that the Creagrura wasps find and oviposit in the caterpillar when it is exposed at night, rather than when it is concealed during daylight hours.
Le recours à la médiation familiale au Québec : exploration des facteurs sociodémographiques et contextuels
Authors: Godbout Élisabeth , Poitras Karine , Clouet Johanne
Published: October 2022

Au Québec, la médiation familiale est devenue une pratique pleinement institutionnalisée à la fin des années 1990, mais ce n’est que tout récemment qu’un état des lieux de son utilisation dans la population générale a été dressé. Le présent article s’appuie sur les données du temps 1 de l’Enquête longitudinale auprès des parents séparés et recomposés du Québec (ELPSRQ) afin d’examiner le recours à la médiation familiale par les parents récemment séparés. Ces données confirment que la médiation est largement utilisée et identifient des caractéristiques sociodémographiques (revenu et statut matrimonial) et contextuelles (violence conjugale et familiale) qui permettent de comprendre cette utilisation. Ces constats sont interprétés à la lumière des connaissances sur l’accès à la justice civile.
Les agences de recouvrement des pensions alimentaires, instruments d’une politique de soutien aux familles monoparentales
Authors: Collombet Catherine
Published: October 2022

Cet article procède à une comparaison des agences de recouvrement des pensions alimentaires dans six pays occidentaux, en étudiant leurs conditions de création et leurs prérogatives. Si les pays présentés ici ont en commun de confier des prérogatives de traitement des impayés de pension alimentaire à un organisme public administratif, le type d’organisme public est très variable (sécurité sociale, agence dédiée, services fiscaux ou autorité locale) et dépend du contexte institutionnel national. L’examen des prérogatives des agences permet de distinguer deux modèles : un modèle d’intervention large, incluant la fixation de la pension et une intermédiation a priori, indépendamment de tout impayé ; un modèle centré sur l’intervention en cas d’impayé, articulé avec une garantie publique.
Ouvrir la boîte noire des chiffres : étudier les catégories statistiques de la migration irrégulière à l’échelle européenne
Authors: Adam Pauline
Published: October 2022

Résumé La migration irrégulière est à la fois difficile à définir et à circonscrire, en raison des situations très différentes qu’elle recouvre, mais aussi à quantifier tant elle est « peu visible » et compliquée à saisir d’un point de vue statistique. Pourtant, différentes données statistiques sur l’évolution des franchissements irréguliers des frontières extérieures de l’Union européenne et de l’espace Schengen sont régulièrement médiatisées. D’où viennent ces chiffres ? Comment sont-ils construits ? Avec quelles catégories statistiques ? Cet article présente la manière dont une recherche doctorale en cours sur les chiffres de la migration irrégulière au niveau européen interroge les catégories statistiques et ce qu’elles « font » à l’enquête. Il propose notamment de s’appuyer sur les outils de la sociohistoire de la quantification pour étudier le processus de catégorisation des statistiques. La présente contribution explicite ainsi les enjeux méthodologiques et théoriques de l’enquête en interrogeant à la fois les différentes catégories statistiques de la migration irrégulière utilisées au niveau européen et les spécificités d’une telle enquête à l’échelle européenne.
L’hébergement public et privé des exilés au prisme des catégorisations administratives
Authors: Ollitrault Chloé
Published: October 2022

Résumé Cette contribution vise à mettre en lumière l’influence des catégorisations administratives des personnes exilées sur leur accès au logement et à l’hébergement, public d’une part, dans des structures d’accueil institutionnelles et des centres d’hébergement d’urgence, et privé d’autre part, chez des particuliers accueillant bénévolement des exilés à leur domicile. À travers une étude du paysage de l’hébergement dans le département du Calvados, en Normandie, l’article essaie de saisir les processus de classement et de hiérarchisation des exilés à partir de leur statut administratif. Les catégorisations administratives sont un élément central de la structuration du droit au logement et à l’hébergement des étrangers, et il existe, de plus, des écarts entre les règles juridiques et leur mise en pratique. Les collectifs locaux d’hébergement privé, qui élaborent leur action par rapport aux besoins des exilés rencontrés sur le terrain, sont également amenés à faire des choix dans la prise en compte des statuts administratifs. Selon leur positionnement, ils conçoivent l’hébergement privé comme un accueil transitoire, inconditionnel, ou d’urgence, tout en adaptant leur action aux évolutions des politiques publiques et des dispositifs d’accueil institutionnel des exilés. Nous verrons que même lorsque les hébergeurs souhaitent initialement s’écarter des hiérarchisations administratives, leurs pratiques d’accueil finissent par être influencées par le poids de la précarité multiforme et souvent durable subie par les exilés. À l’échelle des collectifs comme à celle de chaque cohabitation, l’hébergement privé des personnes ayant le moins de chances d’obtenir la régularisation de leur situation administrative présente de nombreuses difficultés.
Faire participer les « mères immigrées » au « foyer finlandais »
Authors: Haapajärvi Linda
Published: October 2022

Résumé L’émergence de la démarche participative constitue une des tendances majeures des politiques d’intégration déployées dans différents pays européens à partir des années 2010. Néanmoins, les résultats des dispositifs participatifs restent peu connus. À partir d’une enquête ethnographique réalisée à Kamppila, un quartier populaire et multiethnique d’Helsinki, cet article appréhende les dynamiques d’appartenance et d’exclusion à l’œuvre lors des rencontres hebdomadaires organisées par les travailleurs sociaux de la maison de quartier à destination des femmes et des mères au foyer, en analysant les catégories qui sont mobilisées dans le cadre de ce dispositif. Il montre que le périmètre des catégories générales « femmes immigrées » et « communautés locales » dépend du contexte institutionnel et évalue les conséquences de ces enjeux catégoriels sur la position des femmes migrantes au sein de la société finlandaise.
Parcours migratoires et d’autonomisation de Chiliennes exilées en France
Authors: Garcia Yvette Marcela , Moreno Garcia Maider
Published: October 2022

Résumé Au Chili, le putsch du 11 septembre 1973 met violemment fin au gouvernement de l’Unité populaire (coalition de partis de gauche présidée par Salvador Allende, au pouvoir de 1970 à 1973). Entre 1973 et 1990, des dizaines de milliers de Chiliens et de Chiliennes, persécutés par la junte désormais au pouvoir, sont contraints de s’exiler ; près de 15 000 d’entre eux s’installent alors en France. Cet article analyse les parcours de Chiliennes exilées en France afin de rendre compte de leur processus d’autonomisation à la lumière de leur participation sociale et des reconfigurations des rôles sociaux de genre. Pour ce faire, nous présenterons les cheminements de Chiliennes exilées en France dans le monde du travail, dans leur rapport au politique et dans leur vie conjugale. L’étude de leurs parcours et de leurs expériences en exil révèle des formes de réappropriation du politique.
Quel rôle pour les coopératives dans l’écologisation et la numérisation de l’agriculture ? L’exemple de la viticulture en Occitanie (France)

Published: October 2022

L’article analyse le rôle que jouent les coopératives dans l’écologisation et la numérisation de la viticulture. L’enquête menée en Occitanie montre que pour ces deux processus, elles jouent un rôle d’intermédiaire entre les adhérents et les autres acteurs du système d’innovation. Elles participent aussi directement à ces innovations via des investissements ou des expérimentations. Mais les liens entre les projets d’écologisation et de numérisation sont limités, contraints par l’offre technologique et les politiques publiques, même si plusieurs coopératives cherchent à construire des synergies entre ces processus.
Outer space branching search method for solving generalized affine fractional optimization problem
Authors: Ma Junqiao , Jiao Hongwei , Yin Jingben , Shang Youlin
Published: October 2022

This paper proposes an outer space branching search method, which is used to globally solve the generalized affine fractional optimization problem (GAFOP). First, we will convert the GAFOP into an equivalent problem (EP). Next, we structure the linear relaxation problem (LRP) of the EP by using the linearization technique. By subsequently partitioning the initial outer space rectangle and successively solving a series of LRPs, the proposed algorithm globally converges to the optimum solution of the GAFOP. Finally, comparisons of numerical results are reported to show the superiority and the effectiveness of the presented algorithm.

Investigation of reflection bands of 1D annular photonic crystal containing double negative index material and non-magnetized plasma
Authors: Aghajamali Alireza , Srivastava Sanjeev K. , Nayak Chittaranjan
Published: October 2022

In this paper, optical reflectance properties of an annular photonic crystal (APC) composed of alternate layers of double negative (DNG) material and a non-magnetized plasma (NMP) layer, immersed in free space, have been theoretically investigated and studied. The reflectance spectra of the annular PC have been obtained by employing the transfer matrix method (TMM) for the cylindrical waves in the case of TEpolarized wave only. It has been found that the spectral position and width of the reflection bands of APC are greatly influenced by the variation in the thickness of DNG metamaterial and NMP layer, respectively. Interestingly, it is observed that the presence of NMP layer causes the increase in photonic band gap (PBG) whereas the DNG layer reduces the PBG. Further, the effect of azimuthal mode number (m) on the reflectance spectra shows that for m > 0, splitting in the reflection bands occurs at the frequency corresponding to the zero permeability value of DNG metamaterial layer. Moreover, with the increase in azimuthal mode number one PBG is red-shifted and the second one is blue-shifted. Finally, the effect of change in the starting radius parameter of curved surface and plasma electron density on the reflectance spectra of APC has also been studied and very interesting results have been observed.
Application of artificial neural network for the ionizing radiation particle identification by the plastic scintillation detector response
Authors: Garankin Jevgenij , Plukis Artūras
Published: October 2022

The separation of ionizing radiation particles is an important and challenging task, especially regarding neutrons and gamma rays. The separation of neutron and gamma radiation is necessary for safeguard purposes and control of nuclear reactions. Standard mathematical models of pulse analysis work well in the presence of large energy transfer (>1 MeV) from the particle to the detector. However, the quality of the separation decreases as the amount of transferred energy lessens, making it impossible to determine the exact type of particle at a sufficiently low-energy level.

In this work, an artificial neural network model was used to solve the problem of separation at low-energy levels. The supervised machine learning (ML) model was used to analyse pulses received from the polyethylene naphthalate (PEN) scintillation detector. Several data sets after the PEN exposure to neutron/gamma (combined 239PuBe and 238PuBe source), alpha (238Pu) and beta (90Sr/90Y) sources were used to train the models. The information obtained from the separation of neutrons and gamma particles was compared with the information obtained using standard pulses delayed fluorescence analysis methods. The obtained results showed that the model was able to separate particles in the fields of low- and high-energy transfer.
Coronal stop lenition in French and Spanish: Electropalatographic evidence
Authors: Colantoni Laura , Kochetov Alexei , Steele Jeffrey
Published: October 2022

Lenition of voiced and, to a lesser extent, voiceless stops is widely attested in Western Romance languages. In Spanish, utterance-initial voiced stops as well as those following nasals alternate with approximants in intervocalic position. Acoustic and articulatory studies have revealed factors that condition phonetic weakening. In contrast, very little is known about stop weakening in French. In this paper, using electropalatography, we provide articulatory evidence for the lenition of /t d/ in both Spanish and French. Data obtained from seven Spanish-speaking and four French-speaking participants reveal that, in both languages, /d/ is produced with less linguopalatal contact than /t/, and these differences are strongly conditioned by the position within the utterance or word. The languages differ, however, in the degree of /d/ lenition as well as in some of the contextual conditioning factors. Overall, our results, which should be interpreted with some caution given the number of speakers and the balance of the stimuli set, show that French resembles other Romance languages in its phonetic patterns of lenition, differing mainly in the degree of weakening.

Dialectique Orient-Occident. La mise en récit historique de l’art religieux en France par Émile Mâle
Authors: Beaud Mathieu
Published: October 2022

Émile Mâle a publié sa trilogie sur l’art médiéval entre 1898 et 1922, avant d’ouvrir ses réflexions, à la décennie suivante, sur l’art religieux après le concile de Trente. Cet article explore comment l’auteur y articule en un récit logique les périodes de l’art religieux en France par un aspect transversal aux volumes de sa première trilogie : les relations entre l’Orient et l’Occident telles qu’elles apparaissent dans les œuvres d’art et, plus précisément, le rôle d’inséminateur de l’Orient sur l’Occident à chaque changement de période artistique. Cette mise en relation dépasse les cadres de l’influence et du transfert de formes et de motifs ; c’est un rouage de la pensée de Mâle qui agit comme un procédé narratif dans son écriture. Une telle dialectique doit être replacée dans un imaginaire savant historiciste propre au milieu contemporain de Mâle qui perçoit ainsi, dans la durée de l’histoire ancienne, les mouvements des civilisations qui ont enfanté la France en tant que Nation.
L’historien en producteur d’images. Mises en récit de l’architecture moderne durant l’émergence du postmodernisme
Authors: Farret Pierre
Published: October 2022

Cette contribution interroge l’élaboration, par les images, des histoires critiques de l’architecture moderne écrites dans la conjoncture de l’émergence du postmodernisme (1973-1982). Sous la plume de Charles Jencks, Manfredo Tafuri et Francesco Dal Co, Kenneth Frampton et William J. R. Curtis, ces récits mobilisent un large corpus de représentations architecturales au service d’une structure narrative qui vise à déconstruire l’image canonique du Mouvement moderne. Dans ce cadre, les historiens engagent une opération de destitution des images-icônes suivant plusieurs modalités (vision binoculaire, décomposition analytique des édifices par la photographie) ; ils développent une critique des organes de diffusion et de contrôle des images, qu’ils cherchent à détourner ; enfin, ils se font eux-mêmes producteurs d’images critiques à travers la pratique de la photographie.

Published: October 2022

The influence of facial appearance on people’s mental confidence is well-known in the modern life. The aim of this study was to evaluate the clinical efficacy of human-derived collagen gel injection on nasolabial folds and reveal a safe and cost-reasonable candidate for aesthetic and therapeutic cases. This assessment was a quasi-experimental interventional study on patients referred to the plastic surgery clinic of Imam Hospital in 2016–2017 who intended to treat nasolabial folds with outpatient methods and rapid recovery time regardless of age and gender restrictions. Allogenic collagen was injected at the site of nasolabial folds and the durability of the fillers was evaluated by the researcher, the neutral examiner and the participants based on the wrinkle severity rating scale (WSRS) and the global aesthetic improvement scale (GAIS). In terms of severity of nasolabial folds before intervention, the mean and severe state comprised 37 (69.81%) and 16 (30.19%) patients, respectively. The majority of subjects (more than 80%) in both assessments (the examiner and the researcher) demonstrated the improvement of the folds. The agreement between the two evaluators was relatively approximate ([Formula: see text] and [Formula: see text]). Regardless of the evaluation group, the trend of changes was statistically significant ([Formula: see text]). Eventually, the duration of the filler efficacy was estimated to be 4–6 months. The allogenic collagen filler is recommended as an almost safe and cost-effective agent for nasolabial fold treatment in short to medium periods in case of low risk of the transmission of contamination and no need for allergic testing.
Implementing Sustainability in Library Instruction
Authors: Wahl Erin Renee , Kew Kristin , Zubia Jessica Theresa
Published: October 2022

This chapter shares the process and rationale behind a library workshop with the Reference and Research Services Department and Archives and Special Collections Department at the New Mexico State University Library. The workshop was part of a grassroots social justice initiative aimed at forming a more equitable and sustainable library instruction program. The concepts of equity, economy, and environment taken from the 4th U.N. Sustainable Development Goal and the extant literature in the fields of library instruction and educational leadership were utilized to plan and implement this workshop and research. Holmes's definition of positionality was used as the theoretical framework. This chapter unpacks the learning and reflection from an initial meeting with library staff to craft individual positionality statements that will be used to co-create a crowdsourced mission statement informed by positionality and core values.

Customer satisfaction is the central focus of typical library and information services and operations. The chapter examines the extent to which CC services assumed reliable strategies for proactive 21st-century librarians in making their services relevant and impactful towards the satisfaction of the information needs of their customers (clientele). It also made an effort to discover the significance of the customer care (CC) in the special library with respect to its application in boosting absolute customer satisfaction. Recommendations made at the end of the study emphasize the adoption of customer care practices and principles by 21st century librarians towards better customer service delivery among other benefits.
Library Education in Africa
Authors: Olubiyo Peter Olubunmi
Published: October 2022

The concept of library developed when people started reading and writing, but the need of library education was felt in the late 19th century when the concept of library changed from store house to service institution. Globalization of education, complex nature of demands of the users, explosion of knowledge and literature, and innovation of information technology also had a role to play in the establishment of library schools which bring about library education all over the world. As a result, a large number of library and information science (LIS) schools were set up to produce competent professionals who could achieve the objectives of libraries and information centres effectively and efficiently for library sustainability. Librarianship in Africa owes its origin to colonialism. The history of library education was traced in Nigeria, Ghana, and South Africa. The chapter concluded that the existing ICT laboratories in all library schools in Africa should be well equipped while the library schools without laboratories should be encouraged to establish one.
COVID-19 Pandemic's Socio-Economic Impact on SMEs
Authors: Baporikar Neeta
Published: October 2022

The COVID-19 pandemic global health crisis has also snowballed into social and economic crises. Globally, around 75 million confirmed cases were reported until December 2020, with about 1.6 million deaths. The pandemic resulted in lockdowns and brought economic activities to a standstill. This severely impacted all business organizations and more so the small and medium-sized enterprises (SMEs). SMEs' problems resulted due to lockdown, movement of migrant labor, paucity of funds, and lack of technology. Adopting an exploratory approach based on a systematic literature review of published directories, journals, and reports, the objective of this study is to deliberate on the social and economic impact of the COVID-19 pandemic on SMEs in general and India in particular. Thus, the focus is on exploring the upcoming trends, providing recommendations to deal with the issues, and sketching the future research areas in this particular domain. Findings reveal a reduction in active employment, distress of migrating employees, and a fall in income-generating sources.

Global public health will be severely impacted by the successive waves of emerging COVID-19 disease. Since 2019 people get sick and die in our daily lives placing a massive burden on our health system. One of the crucial factors that has led to the virus's fast spread is a protracted clinical testing gap before discovering of a positive or negative result. A detection system based on deep learning was developed by using chest X-ray(CXR) images of Covid19 patient and healthy people. In this regard the Convolution Neural Network along with other DNNs have been proved to produce good results. To improve the COVID-19 detection accuracy, we developed model using the deep learning(CNN) approach where we observed an accuracy of 96%. We validated the accuracy by using same dataset through a pretrained VGG16 model and an LSTM model which produced excellent reliable results. Our aim of this research is to implement a reliable Deep Learning model to detect presence of Covid-19 in case of limited availability of chest-Xray images.

A Rare Case of Purely Cutaneous Rosai–Dorfman’s Disease
Authors: Jadhav Sushanti , Dongre Atul , Darkase Bhushan , Dandale Ameet
Published: October 2022

Rosai–Dorfman’s disease (RDD) is sinus histiocytosis with massive lymphadenopathy. Cutaneous RDD is a rare entity that presents with isolated skin involvement without any systemic involvement. We report a 35-year-old man with an asymptomatic large nodule on the preauricular region of the face with an irregular surface and multiple yellow studded nodules. On detailed physical and systemic examination, there was no lymph node or systemic involvement. Skin biopsy on histopathology showed dense dermal inflammatory infiltrate and foamy histiocytes with emperipolesis. Immunohistochemical markers were positive for S100 protein and CD68 protein but negative for CD1a. Thus, a diagnosis of cutaneous RDD was made.

Nail examination is an important aspect of a wholistic dermatological examination, which when overlooked leads to missing out on important and interesting relevant findings. We observed one such typical interesting finding in a patient who presented to the out patient department with characteristic nail changes suggestive of habit tic type of onychotillomania as an incidental finding. Further, dermoscopy of the affected nails showed characteristic features of the same.

Purpose:

Sharing experiences of complications with robotic-assisted laparoscopic radical prostatectomy (RALP) in 2000 patients treated by a single surgeon.

Materials and Methods:

We retrospectively reviewed 2,000 prostate cancer patients who underwent RALP (Group I, cases 1–1,000; Group II, cases 1001–2000) from December 2005 to September 2020 to compare the complications of the first 1000 patients with those of the latter 1000. All procedures were performed by the same experienced surgeon. Perioperative surgical complications were classified using the Clavien–Dindo classification. Complications were classified as minor (Clavien–Dindo Grades I–II) and major (Clavien–Dindo Grades III–IV), respectively. There was no Grade V complication.

Results:

Seventy-two cases developed complications in Group I: 26 with Clavien–Dindo Grade I, 29 with Grade II, 12 with Grade III, and 4 with Grade IV. The cases that developed complications in Group II, however, were lower at 48 cases: 15 with Clavien–Dindo Grade I, 17 with Grade II, 15 with Grade III, and 1 with Grade IV. Cases with minor Clavien–Dindo Grade (I–II) complications decreased significantly from Group I to Group II, at 55–32 patients (P = 0.0416). The transfusion rate was 1.1% in Group I, which was significantly higher than that in Group II at 0.1% (P = 0.0151).

Conclusion:

The assessment of the two groups indicated that the surgeon's learning curve for RALP improved with significantly fewer minor Clavien–Dindo Grade (I–II) group complications after 1000 surgeries.

Published: October 2022

Разрезание многоугольника задается проведением нескольких диагоналей, не пересекающихся по внутренним точкам. В работе определяются торические многообразия типа Шрeдера - гладкие алгебраические торические многообразия, ассоциированные с разрезаниями многоугольников. Торические многообразия типа Шрeдера являются многообразиями Фано и обобщенными многообразиями Ботта и изоморфны тогда и только тогда, когда соответствующие деревья Шрeдера совпадают как неупорядоченные корневые деревья. Описаны кольца когомологий торических многообразий типа Шрeдера в терминах ассоциированных деревьев Шрeдера. Обсуждается проблема когомологической жесткости.

Community empowerment and sustainability of forest conservation projects in Kenya
Authors: Mwambeo Humphrey Mwandawiro , Wambugu Lydiah Nyaguthii , Nyonje Raphael Ondieki
Published: October 2022

This study investigated the inf luence of community empowerment on the sustainability of forest conservation projects in Kenya. It has been observed that many forest conservation projects cease as soon as financial support ends hence the need to investigate the phenomenon. This study was undertaken in the South-Eastern part of Kenya within Taita-Taveta County. Cross sectional survey design was used in the study. The study hypothesized that “There was no statistically significant relationship between community empowerment activities and sustainability of forest conservation projects.” It targeted 4138 household heads in five administrative locations considered as clusters in this study. Mixed research methods were used in the collection and analysis of data. A total of 365 quantitative data respondents were selected systematically, while qualitative data respondents were selected purposively. The study ascertained that at least 44.1% of respondents at least agreed that forest projects were sustainable, while 3.9% disagreed. Approximately 52% of respondents neither agreed nor disagreed that forest conservation projects were sustainable. Regression analysis showed F-ratio values of F (4,360) = 66.438; p < 0.05. The null hypothesis was therefore rejected. The study also ascertained that community empowerment influenced the sustainability of forest conservation projects. The researcher recommended that community empowerment activities be factored into future projects during the design stage to bolster sustainability.
