Gestion de l’eau d’irrigation dans le Bas-Sahara algérien : le paradoxe hydrique de la palmeraie d’Ouargla
Authors: Amrani Khaled
Published: April 2021

En 1998 paraissait un article de Marc Cote, un géographe Français : « les oasis malades de trop d’eau ». Était pointé du doigt l’excédent hydrique dû aux irrigations à outrance qui résultaient de pratiques inappropriées et d’une gestion défaillante. La situation ne s’est guère améliorée depuis plus de 20 ans. Pire, la palmeraie se dégrade à cause de ce qui devait être son facteur de développement : l’eau. Nous passons en revue les logiques qui sous-tendent les modes de gestion actuels en tentant d’expliquer les raisons de tels dysfonctionnements.

L’ homo panicus et ses fantômes
Authors: Hachet Pascal
Published: April 2021

Un examen de la littérature scientifique montre que les attaques de panique sont peu étudiées par les psychanalystes. Un élément d’explication de cette réalité paraît résider dans le fait que l’attaque de panique n’est ni une phobie ni un autre compromis symptomatique. L’auteur considère que cet état de crise soumis à la compulsion de répétition signe plutôt le « travail d’un (ou de plusieurs) fantôme(s) dans l’inconscient » et propose un repérage clinique et théorique ad hoc . Surtout, il décrit ensuite la convocation prudente de la terreur panique dans la relation thérapeutique et la mise en crise avisée de la « machinerie » fantomatique sous-jacente. L’auteur compare enfin le travail analytique ainsi réalisé à un minutieux jeu de mikado qui serait scandé de phases tauromachiques.
La Covid et le surgissement imprévu de la Chèvre et de l’Oiseau-Lyre
Authors: Siraudeau Diane
Published: April 2021

Ces quelques lignes tentent de traduire l’expérience traversée depuis le début de la crise sanitaire. Elles révèlent l’écart entre ce qui pourrait être théorisé avec le recul, et ce qui a été vécu et pensé au plus fort de cette crise, dans ce que j’appellerai un éprouvé-pensé. Cette expérience est venue interroger profondément l’essence même de ma pratique clinique comme psychologue en libéral et dans un foyer d’accueil Mmédicalisé. Elle me questionne sur les nouvelles voies ou postures que la psychanalyse aurait à inventer, de manière urgente, pour entendre la souffrance actuelle.
Nise da Silveira et le monde des images
Authors: Reis de Almeida Prado Lídia , Landa Alexandra , Landa Eva
Published: April 2021

Nise da Silveira (1905-1999), née à Alagoas, Brésil, est un nom connu au sein de l’avant-garde de la psychiatrie internationale. En travaillant avec des schizophrènes dans un hôpital psychiatrique à Rio de Janeiro, elle s’est opposée à la psychiatrie de l’époque (camisoles de force, électrochocs, lobotomies). En utilisant de façon originale l’ergothérapie, elle a offert à ses patients l’opportunité d’exprimer leurs émotions au moyen de plusieurs formes artistiques. Elle a fondé le Musée des Images de l’Inconscient et a exposé dans plusieurs pays, comme la France et la Suisse, les travaux des schizophrènes. Elle a aussi été une pionnière dans l’utilisation d’animaux comme auxiliaires des processus thérapeutiques. Elle est l’auteur de textes de psychologie et de philosophie et a obtenu la reconnaissance de ses contemporains et de la postérité.
Ascensions et plafonnements. Les modèles genrés des carrières des cadres du ministère de la Culture
Authors: Jacquemart Alban , Charpenel Marion , Demonteil Marion , Hatzipetrou-Andronikou Reguina , Marry Catherine
Published: April 2021

Dans l’administration, les carrières des femmes progressent sous le plafond de verre. Au-delà des chiffres, l’analyse des trajectoires des fonctionnaires du ministère de la Culture révèle la dynamique organisationnelle de ces inégalités. Fondée sur les récits de vie de 65 membres de l’encadrement supérieur (administration centrale et Drac), cette étude sociologique met ainsi en évidence des trajectoires aux contours nettement genrés. D’abord, les trois quarts des hommes rencontrés ont une trajectoire ascendante tandis que plus de la moitié des femmes rencontrées ont une trajectoire plafonnée. De plus, les chemins de l’ascension et du plafonnement ne sont pas homogènes, comme le révèle la typologie en cinq grands types de trajectoires. Les trajectoires ascendantes montrent que le ministère de la Culture offre de beaux « rebonds de carrière » quasi exclusivement aux hommes, ne récompense que quelques « bons et bonnes élèves de la mobilité » et autorise de rares carrières féminines « exceptionnelles ». Les carrières plafonnées distinguent pour leur part des « piégés de la mobilité », un peu plus souvent des hommes, issus d’autres administrations et qui ne parviennent plus à progresser à la Culture, et des femmes « prisonnières de l’autochtonie », ayant effectué toute leur carrière dans l’administration culturelle sans réussir à en gravir les échelons.
Propositions d’évolution des CMP
Authors: Chambry Jean
Published: April 2021

La situation globale du paysage sanitaire a considérablement évolué depuis la création des centres médico-psychologiques ( cmp) . Les demandes sont en augmentation constante, les files actives se sont multipliées jusqu’à saturation des possibilités de réponses. Malgré un travail de priorisation et de hiérarchisation des demandes effectué par la plupart des cmp , les délais d’attente pour la première consultation, comme pour la mise en œuvre du projet de soin et d’interventions, restent en moyenne trop longs. Ceci justifie un réexamen des fonctions du cmp . Il pourrait organiser ses missions autour de deux axes : 1/ «  Accueil, primoévaluation diagnostique, orientation et soins de courte durée » ; 2/ « Diagnostic approfondi et soins pour troubles complexes » . Ces deux axes seront donc réalisés dans deux sous-unités du cmp distinctes mais coordonnées. Cette nouvelle organisation permettrait de réduire les listes d’attente, en proposant une primoévaluation diagnostique, une orientation adaptée à chaque situation.
La situation de handicap au CMP
Authors: Pelloux Anne-Sylvie , Pelloux Anne-Sylvie
Published: April 2021

De sa place de clinicien en centre médico-psychologique ( cmp) , l’auteur s’interroge sur l’évolution conceptuelle de la notion de handicap. Du xix e  siècle à aujourd’hui, le sort des enfants « idiots », inadaptés, incurables ou handicapés s’est transformé. Plusieurs fils de nature historique, politique, sociétale, bio--psycho--médicale, et anthropologique s’intriquant aux différentes couches sédimentaires de lois et de réglementations, encadrent et façonnent le paysage actuel des structures sanitaires et médico-sociales, accueillant ces enfants. L’auteur défend l’intérêt de reconsidérer la situation de handicap dans son sens contemporain, c’est-à-dire en regard d’un environnement donné, et souligne l’écueil d’une position qui consisterait à en craindre son usage et son hypothétique pouvoir surdéterminant.
CAMSP et psychiatrie infanto-juvénile
Authors: Dugravier Romain , Larnaudie Pauline , de Courson Françoise
Published: April 2021

Les centres d’action médico-sociale précoce (camsp) et les centres médico--psychologiques ( cmp) partagent nombre de caractéristiques communes : des soins ambulatoires, de proximité, menés par des équipes pluridisciplinaires, destinés aux enfants et à leurs parents, alliant prévention et soin. Quand l’un relève du médico-social et se destine aux enfants en situation handicap, l’autre relève du sanitaire et incarne le pivot du secteur de psychiatrie infanto-juvénile. Il apparaît que leurs missions respectives sont parfois difficiles à différencier pour les familles comme pour les professionnels qui adressent les patients. Reprendre une partie de l’histoire de l’Institut de puériculture de Paris, creuset de la création de services précurseurs pour les camsp comme pour les cmp, nous aidera à mieux comprendre les enjeux et à adopter une perspective contemporaine. Enfin, y travaillant tous les trois aujourd’hui, nous avons souhaité développer des pratiques soutenant les complémentarités tout en affirmant nos singularités.
Parle à mon corps, ma tête est malade ! L’Unité d’accueil et de crise de l’adolescent : un maillon entre la pédiatrie et les centres médico-psychologiques
Authors: Jahier Sylvie , Kurztag Clara , Marin Mariana
Published: April 2021

Les adolescents en souffrance psychique nous mettent au travail et nous obligent à décloisonner nos institutions. Le partenariat entre les services de pédiatrie et les centres médico-psychologiques ( cmp) devient une réalité nécessaire pour le bien-être de nos patients. Il s’agit de réunir deux fonctionnements et deux temporalités. C’est une rencontre unique entre deux cultures différentes, qui se complètent et se nourrissent l’une l’autre. Nous évoquerons les liens qui unissent la pédiatrie et les cmp à travers une unité de médecine de l’adolescent : l’Unité d’accueil et de crise de l’adolescent de l’hôpital de Neuilly-sur-Seine.
Which Kind of Blockchain Application for Local Complementary Currencies?
Authors: Seang Sothearath , Torre Dominique
Published: April 2021

Cet article examine les possibilités d’application d’une technologie de type blockchain au fonctionnement de monnaies complémentaires locales, en considérant deux types de protocoles de consensus : la preuve de travail et la preuve d’enjeu. Il s’attache en particulier à étudier leur application au contexte de digitalisation de ces monnaies. Une blockchain associée à une monnaie complémentaire locale se distingue profondément d’une blockchain associée à un crypto-actif : elle exclut tout usage spéculatif à la monnaie locale qui, contrairement aux crypto-actifs, a une parité fixe avec la monnaie légale et dispose d’un bassin de circulation restreint. Dans un tel cadre, une blockchain rend des services différents, elle a aussi des propriétés différentes. Le choix du protocole de consensus compte cependant, de même que le type d’incitation poussant les mineurs ou les validateurs à participer au réseau.
Transfers of energy through fast diffusion channels in some resonant PDEs on the circle
Authors: Giuliani Filippo
Published: April 2021

In this paper we consider two classes of resonant Hamiltonian PDEs on the circle with non-convex (respect to actions) first order resonant Hamiltonian. We show that, for appropriate choices of the nonlinearities we can find time-independent linear potentials that enable the construction of solutions that undergo a prescribed growth in the Sobolev norms. The solutions that we provide follow closely the orbits of a nonlinear resonant model, which is a good approximation of the full equation. The non-convexity of the resonant Hamiltonian allows the existence of fast diffusion channels along which the orbits of the resonant model experience a large drift in the actions in the optimal time. This phenomenon induces a transfer of energy among the Fourier modes of the solutions, which in turn is responsible for the growth of higher order Sobolev norms.
Global existence and decay rates of the solutions for a chemotaxis system with Lotka-Volterra type model for chemoattractant and repellent
Authors: Hattori Harumi , Lagha Aesha
Published: April 2021

We study global existence and asymptotic behavior of the solutions for a chemotaxis system with chemoattractant and repellent in three dimensions. To accomplish this, we use the Fourier transform and energy method. We consider the case when the mass is conserved and we use the Lotka-Volterra type model for chemoattractant and repellent. Also, we establish \begin{document}$ L^q $\end{document} time-decay for the linear homogeneous system by using a Fourier transform and finding Green's matrix. Then, we find \begin{document}$ L^q $\end{document} time-decay for the nonlinear system using solution representation by Duhamel's principle and time-weighted estimates.
A modification of Galerkin's method for option pricing
Authors: Dokuchaev Mikhail , Zhou Guanglu , Wang Song
Published: April 2021

We present a novel method for solving a complicated form of a partial differential equation called the Black-Scholes equation arising from pricing European options. The novelty of this method is that we consider two terms of the equation, namely the volatility and dividend, as variables dependent on the state price. We develop a Galerkin finite element method to solve the problem. More specifically, we discretize the system along the state variable and build new basis functions which we use to approximate the solution. We establish convergence of the proposed method and numerical results are reported to show the proposed method is accurate and efficient.
Joint optimal pricing and inventory management policy and its sensitivity analysis for perishable products: Lost sale case
Authors: Qiao Xue , Wang Zheng , Chen Haoxun
Published: April 2021

In the real world, the demand cannot be depicted exactly because of customer behavior cannot be forecasted without error. In this paper, we study the effect of the error of the estimated price-demand parameters by analyzing the sensitivity of the optimal joint pricing and ordering policy on the price-demand parameters based on a periodic-review, multi-period and lost sale inventory model for perishable products with constant quantity decay rate and price-sensitive demand. Firstly, we formulate the joint pricing and inventory control problem and find the optimal ordering quantity and the optimal price for deterministic price-demand function. The optimal solutions show that the retailer tends to set a lower price in early periods of each ordering cycle in order to reduce the inventory holding costs. Furthermore, the sensitivity of the optimal joint pricing and inventory control system with respect to the price-demand parameters is examined analytically and evaluated numerically. The sensitivity analysis reveals that compared to the optimal ordering quantity, the optimal prices are less sensitive in the demand-price parameters. Finally, according to the findings of the sensitivity analysis, a heuristic method of regulating the estimated demand-price parameters is employed to improve the average profit. 185 words.
Preliminary Report on the Theatre of Smyrna / Izmir and the Excavations (2014-2019)
Authors: Ersoy Akın , Alatepeli Sarp , Şakar Gözde
Published: April 2021

The Theatre of Smyrna, whose presence in the memory of the city of Izmir dates back to the 17th century, begins to appear after the demolition of the modern houses constructed in this area since the 19th century. Excavations carried out in the last 5 years revealed the east part of the cavea and some additions of the stage building. The archaeological excavations realised in the stage building revealed the presence of many sculpture fragments and architectural blocks including friezes with masks, which provide information about the façade of the building in the 2nd century AD. The research has also revealed the existence of various epigraphic findings that shed light on the urban life. While the excavations showed that some parts of the ima cavea and the diazoma were preserved, many figurines and ceramics were also found, which gave an idea about the possible structures around the theatre.
Exploring the Usefulness of User-Generated Content for Business Intelligence in Innovation
Authors: Daradkeh Mohammad Kamel
Published: April 2021

This study presents a systematic approach that integrates the information adoption model (IAM) with topic modeling to analyze the digital voice of users in online open innovation communities (OOICs) and empirically examines the usefulness of UGC with large amounts of redundant information and varying content quality across two dimensions: information quality and information source credibility. A total of 61,227 bug comments were collected from the OOIC of Huawei EMUI and analyzed using binary logistic regression. The results show that information timeliness and completeness have a positive effect on the usefulness of UGC in OOICs; conversely, information semantics have a negative effect on the usefulness of UGC. Prior user experience has no influence on the usefulness of UGC in OOICs, while active user contribution has a positive effect on the usefulness of UGC. The results of this study offer several implications to researchers and practitioners, and thus could serve as a pivotal reference source for further investigation of potential determinants of UGC usefulness in OOICs.

Mechanical Properties and Microstructure Evolution of Typical Over-Aging State Al-Zn-Mg-Cu Alloy during Thermal Exposure
Authors: Cheng Tao Qian , Li Zhi Hui
Published: April 2021

Al-Zn-Mg-Cu alloy have been widely used in aerospace industry. However, there is still a lack of research on thermal stability of Al-Zn-Mg-Cu alloy products. In the present work, an Al-Zn-Mg-Cu alloy with T79 and T74 states was placed in the corresponding environment for thermal exposure experiments. Performance was measured by tensile strength, hardness and electrical conductivity. In this paper, precipitation observation was analyzed by transmission electron microscopy (TEM) and high-resolution transmission electron microscopy (HREM). The precipitations of T79 state alloy were GPⅡ zone, η' phase and η phase while the ultimate tensile strength, hardness and electrical conductivity were 571MPa, 188.2HV and 22.2MS×m-1, respectively. The mechanical property of T79 state alloy decreased to 530MPa and 168.5HV after thermal exposure. The diameter of precipitate increased and the precipitations become η' and η phase at the same time. During the entire thermal exposure, T74 state alloy had the same mechanical property trend as T79 state alloy. The precipitate diameter also increased while the types of precipitate did not change under thermal exposure. The size of precipitates affected the choice of dislocation passing through the particles to affect the mechanical properties.

Successful treatment of idiopathic knuckle pads with a combination of high-dose salicylic acid and urea topical keratolytics: A case report
Authors: Sogliani Davide , Mura Chiara , Tamborrini Giorgio
Published: April 2021

Knuckle pads are benign subcutaneous and usually hyperkeratotic fibromas for which no specific treatments exist. Unspecific treatments are, most of the time, ineffective and a wait-and-see policy is often recommended to patients. However, especially in adolescents, knuckle pads are often poorly tolerated for cosmetic reasons, potentially causing embarrassment and social anxiety. Here we present the case of a young adult successfully treated with a combination of high-dose salicylic acid and urea topical keratolytics. In addition, we provide ideal diagnostic images obtained via high-resolution ultrasonography and histological features that can be used by medical practitioners to better distinguish knuckle pads from other proximal interphalangeal/ metacarpophalangeal joint diseases as also from other diseases inducing swelling of periarticular soft tissues.

Published: April 2021

Stewart–Treves syndrome (STS) is a rare entity with a poor prognosis defined as an angiosarcoma appearing in a specific clinical setting, in 90% of cases in a context of breast neoplasia. Herein, we report a rare case of STS of the upper limb as a complication of primary lymphedema. A 55-year-old male was referred for a large, reddish, necrotic multinodular tumor of rapid extension on the anterior aspect of the right forearm. A biopsy of the lesions was performed, confirming the diagnosis of angiosarcoma. The evaluation of tumor extension showed no distant metastasis. An amputation of the arm was performed. Angiosarcoma as a complication of primary lymphedema is a very rare entity with very poor prognosis.
Management of Vasculitis in Pregnancy
Authors: Patnaik Nabnita , Pradhan Nihar Ranjan
Published: April 2021

Vasculitis in pregnancy is a rare disease-modifying effect on autoimmune connective tissue diseases such as vasculitis and that connective tissue disease can have an adverse effect on pregnancy. It is essential that pregnant women with vasculitis are managed to the highest standards of care in order to prevent negative outcomes not only for the mother but also for the child. Vasculitis in pregnancy is probably underdiagnosed and under-reported; cases of vasculitis are rare and so disease flares may not always be recognized by a general clinician. Preconceptual counseling is critical, and assessment of disease activity, major organ involvement, and risk factors, such as hypertension and renal impairment, will help to guide both the woman and her clinicians as to the risks entailed in embarking on a pregnancy. Such patients are best catered for in multidisciplinary settings where there is access to specialized care from nephrologists, rheumatologists and respiratory medicine physicians, as well as obstetricians and pediatricians skilled in caring for complex pregnancies. This article aims to provide an approach to managing these patients with the best current evidence-based practice.

Published: April 2021

A 4-year-old male child, born to nonconsanguineous parents, was brought with a history of a fleshy red mass in both eyes and abnormally shaped eyelids since birth. Evaluation revealed delayed developmental milestones and temporoparietal alopecia over the right side along with focal areas of hyperpigmented skin over the face, chest, back, and both upper limbs. Ocular evaluation revealed skin tags over the upper eyelids, epibulbar dermoid along with upper lid coloboma, and microcornea in both eyes. He had deformed temporoparietal bones on both sides. Magnetic resonance imaging brain revealed generalized cerebral atrophy with prominent Virchow–Robin spaces and enlarged ventricular system but atypically normal corpus callosum. He was diagnosed as an atypical variant of Delleman syndrome (a rare congenital disorder involving eyes, skin, and brain and comprising orbital cyst, eyelid colobomas, skin appendages, polymicrogyria as well as characteristic mid-hindbrain abnormalities). Multidisciplinary treatment approach and long-term neurological follow-up are recommended in these patients.

Authors: Vannadil Harikrishnan , Jaiswal Sanjana , Sistla Srinivas Kishore , Bathula Shruthi
Published: April 2021

Onodi cells are an anatomic variation in the pneumatization of the ethmoidal air cells. Onodi cells can be affected by various pathologies causing optic nerve manifestations. Being a physiologically immunocompromised state, the clinical course of these etiologies varies greatly during pregnancy. When such conditions are manifested during pregnancy, the armamentarium of the clinician is severely restricted both in terms of investigations and treatment. The first suspicion of such a sight-threatening condition relies majorly on clinical examination. Here, we describe the first documented case of Onodi cell abscess-induced optic neuritis in pregnancy managed with methylprednisolone and transsphenoidal surgery.
Quality of life in patients affected by age-related macular degeneration
Authors: Palsule Aratee C. , Kulkarni Aditi A. , Jathar Ketan V.
Published: April 2021

Context:

Age-related macular degeneration (ARMD) is an eye condition which results in loss of vision because of damage to the retina. ARMD affects central vision, and it shows association with psychological distress and depression.

Aims:

Our study aimed to evaluate the quality of life (QoL) in patients with ARMD and its association with best-corrected visual acuity (BCVA) and treatment. Subjects and Methods: A cross-sectional study including patients clinically diagnosed as neovascular ARMD (wet ARMD) and geographic atrophy (dry ARMD). Patients were classified into Group 1: Patients with dry ARMD, Group 2: Patients with wet ARMD not treated with anti-vascular endothelial growth factor (VEGF) injections, and Group 3: Patients with wet ARMD who had received at least 3 anti-VEGF injections. To assess the vision-related QoL, National Eye Institute Visual Functioning Questionnaire-25 (NEI VFQ-25) was used.

Results:

We included 60 patients, 20 in each group. There were 23 women and 37 men; with mean age of 78.2 ± 7.9 years. We observed significant difference in near activities (P = 0.03), distance activities (P = 0.002), and vision-specific social functioning (P = 0.001), when comparing VFQ-25 subdomain scores with patients with better eye BCVA. We found Group 3 had significantly more vision-specific role difficulties than Group 1 (41.87 ± 21.94 vs. 26.87 ± 25.73). We found Group 2 had significantly better vision-specific mental health (49.37 ± 19.8 vs. 35.31 ± 19.9) and lesser vision-specific dependency than Group 3 (57.08 ± 26.6 vs. 40.00 ± 26.7).

Conclusions:

Vision-specific mental health is better in untreated wet ARMD patients than those who have taken anti-VEGF injections in our study population.
World's Hunger and Obesity Both on the Rise
Authors: Shrivastava Saurabh RamBihariLal , Shrivastava Prateek Saurabh
Published: April 2021

In general, the public health concerns of obesity and hunger appears different, but in reality, the root cause of these problems is overlapping to a great extent. The findings of studies have indicated that childhood obesity and food insecurity can coexist, while in some children and youths, food insecurity has been linked with more risk of development of obesity. Considering the fact that a large section of human population is vulnerable to the threat of food insecurity, it is the need of the hour to take specific interventions to bridge the existing challenges. As the problem has deep roots within the existing system, the first and foremost thing will be to rope in all the concerned stakeholders and plan for a holistic approach. As maintenance of nutrition and ensuring adequate supply of food commodities is an integral aspect of elements of primary health care, the national government should design policies to warrant equitable distribution of food commodities. To conclude, the twin problem of hunger and obesity has demonstrated a significant rise in the different parts of the world. It is of utmost importance to acknowledge the problem as a public health priority and respond to the same in a concerted and organized manner.

Authors: Hassan Adnan Mohammed , Ali Faraj Hamza Hama , Mohammad Hayder Fakhir
Published: April 2021

Objectives:

Due to increasing incidence of Helicobacter pylori infections among children, it is important to understand which diagnostic test among the noninvasive tests is more accurate, specific, and sensitive.

Methodology:

Forty-five children who underwent osophagogastroduodenoscopy by the same pediatric gastroenterologist, with Urea Breath Test (UBT) and Stool Antigen Test (SAT); their data were analyzed by retrospective study (2013–2019) to make a comparison between UBT and SAT (Specificity, Sensitivity, and Accuracy) using biopsy finding (histopathological finding) as confirmatory tool for diagnosis. Patients were selected according to their clinical presentations and inclusion criteria in this study are: (pediatric age group, have clinical presentation of H. pylori infection, full information in history, clinical examination, and tests). Patients with incomplete information were excluded.

Results:

Male (75.56%) more common than female (24.44%), abdominal pain (53.3%) is the major presentation followed by hematemesis (20%), UBT is more influenced by demographic characteristics than other tests, UBT has a statistical significant correlation with result of biopsy, also it is more accurate and more sensitive than SAT, but they share same positive predictive value and same specificity.

Conclusions:

UBT more preferable than SAT specially in children above 6-year-old.
Differentiation of Typical and Atypical Meningiomas Using Magnetic Resonance Imaging
Authors: Nazir Imran , Rafiq Suhail , Naseed Mohammad , Dar Musaib Ahmad , Shaheen Feroze
Published: April 2021

Background:

Meningiomas are the most common intracranial neoplasms. They are usually homogeneously enhancing extraaxial masses. However, 10% of meningiomas are atypical with different imaging appearance. Distinguishing typical from atypical meningiomas on imaging is highly important in surgical and treatment planning.

Materials and Methods:

Our study was a retrospective one comprising twenty cases each of pathologically proven typical and atypical meningiomas excluding enplaque lesions. Magnetic resonance images were reviewed with each of the lesions showed as dural-based enhancing mass. Individual features analyzed were age, gender, maximum size, location, signal characteristics on T1, T2 weighted, susceptibility weighted imaging, diffusion-weighted, apparent diffusion coefficient, contrast-enhanced T1, interface with adjacent brain tissue, signal changes in adjacent brain tissue, and changes in overlying bone.

Aim:

The aim of the study is to retrospectively assess the magnetic resonance imaging (MRI) features of pathologically proven typical and atypical meningiomas.

Results:

Magnetic resonance features such as diffusion restriction, bony changes in form of destruction, indistinct interface with brain parenchyma, heterogeneous postcontrast enhancement, and edematous changes >6 mm thick in adjacent brain parenchyma were in favor of atypical meningioma.

Conclusion:

MRI has the ability to differentiate typical and atypical meningiomas based on imaging appearance which is important in surgical and treatment planning.
Preparing the Western Pacific Region for the Onset of Large-Scale Community Transmission of Coronavirus Disease 2019
Authors: Shrivastava Saurabh RamBihariLal , Shrivastava Prateek Saurabh
Published: April 2021

The Corona Virus Disease-2019 (COVID-19) pandemic continues to remain a public health emergency of international concern. In the Western Pacific region, the estimates pertaining to the caseload and death rates have shown a big improvement, as the region accounts for 1.8% and 1.3% of the global caseload and deaths worldwide. The available estimates clearly suggest that now the epicenter of the disease has shifted to the European and the American region. However, it will be a wrong assumption to presume that the epidemic is over in the Western Pacific region, and thus it will be a premature decision to be complacent about the outbreak readiness and emergency response action plan. In conclusion, the decline in the number of COVID-19 cases in the Western Pacific region is not a time to relax, as any lacunae on our part will result in a resurgence of the disease. The right approach will be to continue the fight against the disease with the support of individuals, families, societies and the health sector and thus prepare ourselves for a large-scale community transmission.
Material waste minimization techniques in building construction projects
Authors: Tafesse Shitaw
Published: April 2021

In Ethiopia, the rapid expansion of the construction sector has resulted in the wastage of construction materials that negatively affect the environment, society, and the economy. The reason is inefficient waste management strategies practiced in construction projects. Hence, an adequate material waste management strategy is required. This study was an attempt to identify the key techniques that can help to minimize material wastage in building construction projects. Questionnaire surveys, interviews, and reviews of previous studies and related literature were employed in gathering the relevant data. Seventy of 85 questionnaires administered and distributed to contractors, consultants, and clients were returned. These data were analyzed using the relative importance index method. The results indicated that employing waste management officers for this purpose, using prefabricated or off-site production of components, appropriate on-site waste management, and incorporating a policy of material waste minimization plan were identified as key measures to minimize construction material wastes.
La pratique de l’intelligence economique dans les entreprises au Cameroun : Enjeux et perspectives
Authors: Hourenatou H.
Published: April 2021

Avec les mutations de l’économie mondiale, l’intelligence économique est un outil d’aide idéal pour le dirigeant dans l’objectif de prévenir les  risques, saisir les opportunités et anticiper les changements de l’environnement. L’objectif de cet article est non seulement de présenter les enjeux et les perspectives de la pratique de l’intelligence économique par les entreprises au Cameroun mais aussi de faire un état des lieux à travers une étude empirique auprès des dirigeants de 62 entreprises. Les données ont été collectées à partir d’un questionnaire administré en face à face auprès des dirigeants ou des cadres pouvant nous fournir des informations sur l’activité d’intelligence économique. Les données ont fait l’objet d’un traitement statistique à l’aide du logiciel SPSS et la méthode du tri à plat a été utilisée pour analyser les résultats. Il ressort de ces résultats que malgré les grands enjeux que présentent la pratique de l’intelligence économique dans les entreprises, cette dernière est encore à l’état de  gestation et reste incomprise par les dirigeants. Des actions de sensibilisation, de formation, de réseautage et d’implication de tous sont nécessaires pour une meilleure implémentation par les entreprises au Cameroun.

Authors: Titanji Vincent PK
Published: April 2021

The ongoing SARS CoV-2 pandemic also known as COVID-19 is a highly infectious and deadly disease that has disrupted socio- economic activities  and killed over 500 000 people worldwide during the past six months since it first erupted in Wuhan China in December 2019.While intensive efforts  are under way in the developed countries to find a vaccine and cure for the disease, Cameroon and other African countries should not fold their hands and wait , but join the search for new remedies including from cures from traditional herbs while rigorously applying barrier and social  distancing measures that have proven effective in in curbing the spread of the disease. Herein we enumerate a short list of research priorities that are feasible in our milieu and that could improve on diagnostics, treatment and prevention of the disease in the short and medium terms.

Prevalence of Periodontitis and Associated Factors among Pregnant Women: A cross sectional survey in Southern Province, Rwanda
Authors: Uwambaye Peace , Kerr Michael , Rulisa Stephen , Harlan Shiau , Munyanshongore Cyprien
Published: April 2021

Background

The literature has shown the relationship between maternal periodontitis and complications associated with pregnancy. Thus, prevalence estimates and risk factor identification for periodontitis during pregnancy in Rwanda are paramount.

Aim

The aim of the current study was to determine the prevalence of periodontitis and identify related risk factors among pregnant women in Rwanda.

Methods

A cross sectional study was conducted to determine the prevalence of periodontal diseases in a convenience sample of 400 pregnant women in the Southern Province of Rwanda. A logistic regression analysis using a hierarchical approach was performed to assess the risk factors for periodontal disease. Socio demographic factors were put in the regression model first followed by a second step for other potential factors.

Results

The overall prevalence of periodontitis was 60.5%. Multivariable logistic regression showed that age OR=2.48 (95% CI. 1.18-5.22), education level OR=82.15 (95% CI. 8.21-822.11), socio economic status OR=2.28 (95% CI. 1.49-6.62), employment status OR=7.3 (95% CI. 1.38-38.74, and tobacco use OR=6.89 (95% CI. 1.78-60.65) were significantly associated with periodontitis.

Conclusion

Periodontitis appears to be a common problem among pregnant women in Rwanda. Risk factor screening could help identify pregnant women at higher risk of periodontal disease.

Authors: O. Bello Oluwasomidoyin , A. Onebunne Chinedum , M.E Takpe Raymond
Published: April 2021

Background

Successful vaginal delivery (VD) is the desire of every parturient. This is however not always so especially for primigravid women. Predictive factors can help the counselling process and allay the anxiety that this group of parturients experience.

Objective

To determine the prevalence and predictors of vaginal delivery among primigravid women at a tertiary health facility.

Methods

This was a 6-month cross-sectional study of 200 primigravid women that were planned for vaginal delivery. Information was obtained using structured proforma. Bivariate and multivariable analysis was used to identify the proximate predictors of VD.

Results

The prevalence of vaginal delivery was 50.0%. Labour onset was spontaneous in 78.0%; 10.0% had engaged fetal head prior to labour onset while labour was augmented in 18.0% of the parturients. Labour lasted ≤12 hours in majority (67.5%) with about half (49.5%) having successful vaginal delivery. Factors predicting successful vaginal delivery were spontaneous labour onset (OR=3.555, 95% CI=1.626-7.774), booked pregnancy (OR=3.008, 95%CI=1.361-6.647), and early fetal head engagement (OR=6.484, 95% CI=1.686-24.943).

Conclusion

The identified predictive factors of vaginal delivery in this study will aid counselling of primigravid women regarding the likelihood of successful vaginal delivery especially in the absence of other obstetric complications.

Published: April 2021

El presente estudio tuvo por objetivo establecer la relación entre Bienestar espiritual y calidad de vida en pacientes del Centro de Salud de Alto Moche. La muestra estuvo conformada por 18 pacientes, con edades entre 18 a 40 años a quienes se les evaluó mediante la escala de bienestar espiritual y El cuestionario SF-36. A través de los resultados, se confirmó la hipótesis de que existe una correlación significativa entre el bienestar espiritual y la calidad de vida, pero esto se da de manera negativa, es decir mientras que la calidad de vida aumenta el bienestar espiritual disminuye en los pacientes del Centro de Salud de Alto Moche, debido a que cuando se encuentran enfermos recurren a su espiritualidad. Además, también refieren que la gravedad de la enfermedad y la calidad de vida varían en todos los pacientes, teniendo en cuenta la espiritualidad también podría variar de manera importante, ya que ante pequeños problemas de salud las personas pueden preocuparse más por el cumplimiento de su trabajo y quehaceres que en la relación con Dios. Mientras que otros autores ven que la espiritualidad aumenta según la gravedad de la enfermedad como por ejemplo el cáncer, diabetes o cuando el paciente se realiza periódicamente hemodiálisis.

Published: April 2021

El presente trabajo de investigación consistió en hacer un mapeo de preferencias acerca de los néctares de fruta envasados más representativos, de durazno, que existen en nuestro país. Estos fueron Liber, Pulp, Frugos y Watts. Por tal motivo, la idea es analizar a través de la técnica estadística del mapeo, cual es el néctar que puede tener mayor aceptabilidad en el consumidor y que características pueden influir en el mismo; ya que nos permite conocer que propiedades debe tener este producto, si en caso se quiere lanzar uno nuevo al mercado. Así mismo, se encuestó y se le hizo pruebas de análisis sensorial a un cierto grupo de personas (familiares y conocidos de los investigadores, por temas del Covid 19), para determinar y puntuar características básicas a modo de los atributos sensoriales tales como el sabor, olor, claridad, espesor, color, entre otras. Posteriormente, los resultados fueron organizados en un Excel para su posterior uso y/o manejo en el programa RStudio. Donde, se realizó el análisis correspondiente a toda esa data de néctares para poder obtener los diferentes resultados de mapas de preferencia a través de gráficos didácticos y representativos, como elipses de confianza, mapa de individuos, entre otros. Por consiguiente, al final del estudio y el análisis se puede afirmar que uno de los néctares con mayor aceptación y preferencia fue el de la marca Líber según nuestra encuesta de consumo, y con respecto al análisis sensorial el más importante fue el néctar Frugos para los panelistas.
La esencia del niño
Authors: González Pérez Francis Carolina
Published: April 2021

Comprender al niño y quién es, ha sido una inquietud durante toda mi vida como educadora. A través de mis años como maestra de educación inicial y luego profesora en una universidad pedagógica, he convivido con niños en diferentes contextos que aún a pesar de sus diferencias e individualidades, parecían compartir cualidades en la esencia de su ser. Al mismo tiempo, pude ir recopilando algunas expresiones en mis cuadernos de campo, entrevistas, talleres para padres e intercambios con estudiantes de la especialidad de educación inicial de pre y postgrado, así como una tesis doctoral acerca del niño y las configuraciones que se tejen a su alrededor, documentos que me llevaron a hacer un escrito final condensado en estas páginas, e incluso representar gráficamente algunas ideas en unos gráficos al final de cada parte. Mi intención es presentar una descripción reflexiva de la figura infantil sin pretensiones academicistas; un texto accesible para todos los que de una u otra manera se interesan por el tema, atienden y educan a los niños. Estar en presencia de un niño es casi siempre una experiencia que nos abre las puertas del corazón, por su carácter convocante de amor y cariño y por la capacidad de asombrarse por todo, actitud que nos contagia. De allí, que escribir este texto ha sido también una experiencia de amorosidad conjugada con el respeto más profundo hacia la humanidad infantil; misma que merece ser develada en un mundo lleno de contrastes y conflictos adultos que a veces poco edifican nuestra condición de ser. Este libro que devuelvo a sus principales actores y versionantes, es tal vez una vuelta a mirar lo bello y sensible de nuestra humanidad, a redescubrir ese niño que fuimos y rescatar sus más anhelados sueños.
