La reconnaissance du droit d’association par les droits canonique et français : une problématique
Authors: Échappé Olivier
Published: April 2021

Il est bien connu que tant le droit français que le droit canonique reconnaisse la liberté d’association. Le premier lui accorde même un statut constitutionnel depuis la décision du Conseil constitutionnel du 16 juillet 1971, tandis que le second la range au nombre des droits fondamentaux du fidèle. Derrière cette apparente similitude se cachent en réalité d’importantes différences. L’article tente de mieux cerner ces différences, les unes formelles, les autres substantielles, et souligne le caractère délicat du travail d’articulation entre les deux droits, nécessaire pour faire vivre la normative canonique dans le cadre du droit français.
L’exercice de la vigilance de l’autorité ecclésiastique à l’égard des associations de fidèles

Les aspects juridiques du vœu de pauvreté
Authors: Canart Jean-Pierre
Published: April 2021

Le vœu de pauvreté n’est pas dans l’esprit du siècle ! Et le droit français peine à en traduire l’existence dans ses catégories. À partir de son travail de licence en droit canonique, l’auteur, notaire honoraire, propose plusieurs pistes pratiques pour permettre l’articulation de cette catégorie du droit canonique sur le droit français.
Le droit canonique au service de l’œuvre catholique d’enseignement
Authors: Greiner Philippe
Published: April 2021

Le droit canonique, comme tout droit a vocation à assumer une fonction régulatrice et disciplinaire, et en cela déjà, il peut être considéré comme serviteur puisque son application intervient, dans l’Église, pour organiser les institutions et garantir la justice. À sa mesure également, le droit canonique contribue à authentifier « le juste ». De surcroît, il incombe au législateur canonique de se laisser inspirer et guider par le souci de la justesse tant aux plans théologique que juridique, afin de faire œuvre efficace et utile dans un esprit de service de l’Église et de façon indirecte, aussi, de service pour le monde. En matière canonique, donc, il ne s’agit plus de s’en tenir aux conceptions exprimées par l’adage Ubi societas ibi jus , trop marqué par l’approche séculière de l’époque moderne. L’auteur applique ces principes à l’œuvre catholique d’enseignement. Dans un premier temps, il examine le rapport entre « mission de l’Église », « éducation catholique » et « œuvres scolaires ». Puis, il s’interroge plus particulièrement sur la notion d’« école catholique », sans suivre en cela les distinctions séculières habituelles entre « école », « collège » et « lycée ».
Organiser le territoire pour moins se déplacer
Authors: Pineau Jean-Yves
Published: April 2021

Dans un monde où les mobilités sont avant tout la résultante d’un système qui se pense hors sol, universel et éternel, il est plus qu’urgent de reconsidérer les fondamentaux de l’aménagement des territoires dans un souci de symbiose entre l’humain et le vivant. Éco-mobilité, tiers-lieux, circuits courts, les solutions ne manquent pas…

Enjeux de l’accompagnement psychologique de la conception médicalisée
Authors: Bourdet-Loubère Sylvie , Rambeaud-Collin Delphine
Published: April 2021

Cet article a pour objectif de penser l’accompagnement psychologique de la conjugalité en service de médecine procréative. La mise en sens de la sexualité du couple a souvent tendance à achopper sur le constat d’infertilité, la rendant potentiellement inutile. Le protocole médical et ses injonctions renvoient alors plus au corps « fonctionnel » qu’à sa dimension libidinale. La présentation du cas de Léna et Paul illustre ce désinvestissement du conjugal au profit du surinvestissement d’un « devenir parent », non sans conséquences sur la dynamique familiale instaurée, une fois l’enfant né.
A Bit of Jewish-American Mischief: Fictional Metabiography in Alan Lelchuk’s Ziff: A Life? and Philip Roth’s Exit Ghost
Authors: Brauner David
Published: April 2021

L’écrivain juif américain Alan Lelchuk a joué un rôle important dans la carrière et la vie de Philip Roth dans les années soixante-dix, bien que les ambiguïtés de leur relation littéraire et personnelle n’aient que peu attiré l’attention de la critique. On s’efforcera de combler cette lacune en abordant le roman de Lelchuk Ziff: A Life? et plus brièvement Exit Ghost de Roth comme des métabiographies fictionnelles qui s’inspirent de cette relation pour aborder sur un mode ironique de plus larges questions éthiques et esthétiques.
L’intérêt de la notion d’« enquête » pour l’analyse du travail en lien avec la formation
Authors: Thievenaz Joris
Published: April 2021

La notion d’« enquête », issue de la philosophie pragmatiste de John Dewey, fait aujourd’hui l’objet d’un intérêt renouvelé au sein des démarches d’analyse du travail en relation avec la formation. Celle-ci se révèle en effet un outil opératoire pour comprendre les rapports entre travail et apprentissage, en analysant conjointement les processus selon lesquels l’acteur réélabore son expérience dans et par l’activité. Afin d’illustrer nos propos, nous nous appuierons sur un exemple issu du champ médical, en montrant comment, en s’appuyant sur la notion d’ « enquête », il est possible de repérer les apprentissages « opportunistes » du médecin en situation de consultation.
Quand la didactique professionnelle s’intéresse aux apprentissages culturels
Authors: Tourmen Claire
Published: April 2021

La didactique professionnelle s’est, depuis son origine, intéressée aux apprentissages professionnels et au développement des compétences pour et sur les lieux de travail (Pastré, 2011). Le cadre théorique et méthodologique de la didactique professionnelle est-il pour autant pertinent si on l’applique aux apprentissages dits « culturels », comme ceux qui peuvent se réaliser lors d’un séjour à l’étranger, à savoir à des apprentissages réalisés dans des situations de la vie de tous les jours ? La question s’est posée à l’occasion d’une recherche réalisée en 2012 pour le Ministère de l’Agriculture, de l’Alimentation et de la Forêt, visant à identifier les apprentissages réalisés par des jeunes lors de mobilités internationales. Nous avons fait le pari que ces apprentissages culturels pouvaient être étudiés avec la didactique professionnelle, au même titre que des apprentissages de tâches ou de situations professionnelles. Nous sommes partis de l’hypothèse que changer de culture de travail et de vie pouvait provoquer des processus de conceptualisation dans différents domaines. Nous allons présenter ici la recherche qui a nourri ces réflexions – menée par le biais d’entretiens d’explicitation auprès de 17 étudiants en Brevet de Technicien Supérieur Agricole (BTSA) partis en stage individuel (de 1 à 3 mois) à l’étranger. Nous montrerons comment nous avons mobilisé la théorie des schèmes de Vergnaud pour analyser les récits de l’expérience à l’étranger ainsi que les questions qui demeurent.
Nouvelles pistes de recherche et évolutions de la didactique professionnelle
Authors: Rogalski Janine
Published: April 2021

On situe les nouvelles perspectives de recherche en didactique professionnelle dans la dynamique de leurs évolutions depuis leur constitution. On illustre les évolutions récentes par les thèmes traités dans Travail et Apprentissages. On relève en particulier la focalisation sur l’expérience, les relations entre situations de travail et de formation, les rapports avec les cadres didactiques disciplinaires. Les nouvelles perspectives sont considérées sous l’angle de l’élargissement de “l’empan” des situations, des changements de points de vue et de cadres théoriques, des questions de concepts, théories et méthodes ; on relève aussi deux thématiques qui demeurent largement absentes : la conception de formation et l’activité des formateurs. Il ressort de l’étude des perspectives le besoin d’un travail réflexif en didactique professionnelle, avec un souci d’expliciter l’utilisation opératoire de concepts qui se déclinent sur des modes multiples, à la fois quotidiens, pragmatiques et scientifiques - et qui peuvent vivre dans plusieurs domaines de recherche. Le besoin aussi d’un travail prospectif pour articuler classes de situations, problématiques et méthodes d’étude, en ne perdant pas de vue le double caractère de la didactique professionnelle : épistémique, dans l’analyse du travail et de ses apprentissages, et pragmatique, dans la conception de dispositifs de formation.
Ouvrages et systèmes d’irrigation du wādī Ḍuraʾ (Yémen) du second millénaire av. J.-C. au milieu du premier millénaire après
Authors: Breton Jean-François , Roux Jean-Claude , Gentelle † Pierre
Published: April 2021

Le wādī Ḍuraʾ, situé au sud-est du Yémen, s’écoule vers le nord - nord-ouest dans une vallée, dans laquelle de petites communautés ont installé des ouvrages hydrauliques dès le IIe millénaire av. J.-C., puis les ont densifiés jusqu’au ve siècle apr. J.-C. Pour la première fois dans cette région, un grand nombre d’ouvrages hydrauliques ont été fouillés, permettant une typologie précise : barrages, muret déflecteurs, vannes, répartiteurs, môles, etc. Il est ainsi possible d’appréhender une organisation minutieuse de l’irrigation en milieu montagneux. Enfin, le tell principal de Hajar al-Dhaybiyya, qui a fait l’objet de deux campagnes de fouille en 1992-1993, démontre l’importance de cette ville, probablement dénommée Drʾ, aux trois premiers siècles apr. J.-C.
Transition énergétique et hydrogène : le Living Lab ou l’ébauche d’une recherche participative
Authors: Amand Rudy , Ducoulombier Pauline , Millet François
Published: April 2021

Les possibilités de décentralisation de la production promises par l’hydrogène offrent des perspectives politiques nouvelles à la transition énergétique. Ainsi, la démarche Living Lab, engagée en Normandie, constitue une expérience originale de « fabrique des publics » reposant sur une méthodologie appliquée habituellement à la co-construction de l’innovation. Engageant acteurs institutionnels, participants, mais aussi organisateurs et chercheurs dans un procédé se rapprochant de la recherche participative, cette initiative devait faciliter une appropriation « commune » de l’hydrogène passant par l’élaboration de scénarios d’usage mobilisant ce vecteur énergétique et leur prototypage. Après avoir présenté les modalités de la mise en œuvre du Living Lab et ses principaux acteurs, cet article tracera l’historique de deux prototypes élaborés en son sein. Ils permettront de mesurer la pertinence de la démarche qui, malgré les contraintes institutionnelles qui pèsent sur elle, reste porteuse de perspectives émancipatrices pour les participants.
Analyser les trajectoires territoriales de transition énergétique
Authors: Lapostolle Dany
Published: April 2021

Cet article propose un essai de grille d’analyse comparative de trois trajectoires territoriales de transition. Il définit la structure d’opportunité territoriale de transition, la capacité énergétique territoriale et le droit à la transition comme critères de lecture de ce qui est à l’œuvre dans la transition énergétique via le vecteur hydrogène. Il montre que si l’hydrogène joue un rôle de médiateur dans la territorialisation de la transition énergétique, celle-ci s’inscrit dans un cadrage techno-économique qui laisse peu de place à des projets territoriaux susceptibles de dépasser les enjeux d’acceptabilité sociale des techniques.
Doit-on s’attendre à un refus du déploiement de l’hydrogène ? Dynamique territoriale et transition énergétique
Authors: Turmel Félix G.R.
Published: April 2021

La transition énergétique est vectrice d’enjeux non seulement environnementaux, mais aussi et surtout politiques, sociaux et économiques. Dans ce contexte, il est nécessaire de ne pas limiter la compréhension de la déployabilité d’une technologie uniquement aux regards de ce qu’elle peut offrir sur un plan techno-scientifique. Le vecteur énergétique hydrogène offre justement une formidable opportunité de comprendre l’impact des tensions et enjeux extérieurs à la dimension techno-scientifique. Cela parce qu’il demeure à la fois bien connu du plus grand nombre, mais sans que ceux-ci ne sachent réellement ce que son déploiement ne signifie vraiment ; qu’il s’agisse des infrastructures ou des pratiques nécessaires à son fonctionnement. Analyser les perceptions d’une technologie industrielle avant qu’elle ne soit déployée permet alors de démontrer les limites de la perception de l’acceptabilité sociale comme résultant uniquement de ladite technologie.
Le leadership partagé, Capillarité et relayage dans la transition énergétique
Authors: Lianos Michalis
Published: April 2021

L’objectif de cet article est de décrire très brièvement les prémisses d’un modèle émergeant de leadership portant sur tous les domaines d’activité, mais dans des mesures différentes. Les initiatives politiques, économiques et technoscientifiques dans le domaine de l’environnement sont particulièrement concernées. Il s’agit de contribuer à la compréhension, l’anticipation et éventuellement l’accélération, des changements dans le fonctionnement du leadership. Le modèle est issu de recherches empiriques approfondies sur les mouvements sociaux, l’incertitude et la complexité des sociétés postindustrielles, la perception du risque et le rôle de l’environnement dans cette perception. Il n’est pas possible d’inclure les liens détaillés à ces travaux dans un seul et même article. Par conséquent, je me concentre ici strictement sur la présentation d’un modèle tout en fournissant un échantillon représentatif des références empiriques de base, tant primaires que secondaires.

Sublingual Haematoma – A Rare Complication associated with Cleft Palate Surgery
Authors: Roy Rajat , Malhotra Aaina , Mahajan Anuj
Published: April 2021

A 1yr old boy weighing 10 kg underwent cleft palate surgery. Post extubation, a swelling was noticed beneath the tongue which progressed gradually and obstructed the airway. Small sized endotracheal tube (ETT) was used as a nasal airway and advanced till it relieved the obstruction and child started maintaining SpO2 >95%. Haemodynamic parameters were stable and child was shifted from OT to PACU where he was observed vigilantly for any airway obstruction. Swelling regressed over the next 2 days and the child accepted oral feeding eventually.
Novel Use of Flexible Paediatric Video-Ureteroscope to Confirm Double Lumen Tube Placement as an Alternative to the Conventional Bronchoscope
Authors: Gupta Bhavna , Kumar Mohit , Praveen Talawar , Amanta Lucy Ittoop
Published: April 2021

Whilst a double lumen tube (DLT) is the gold standard for one lung ventilation, its double curvatures and increased diameter can make intubation difficult, potentially compounded by a challenging airway. We describe the successful placement of DLT in a difficult airway, and confirmation of the appropriate placement of DLT by using flexible paediatric video-ureteroscope (digital Olympus URF-V2/V2R), without which the purpose of achieving lung isolation was not possible.

Change in Mallampati Score during Pregnancy, Labour and Post Labour: An Observational Study
Authors: Shivashankar Archana , Rajappa Geetha C. , Rath Prapti , Deepak K. S.
Published: April 2021

Background Mallampati (MP) score is used to predict the ease of endotracheal intubation. Pregnancy is often associated with failed intubation during anaesthesia for caesarean delivery and contributes majorly to maternal complications that are related to anaesthesia. This study aimed to determine the change in MP grade over the course of pregnancy (first trimester, during labour and post-delivery). Methods The study was conducted on 389 pregnant women in the first trimester. Demographic data, airway characteristics and MP score of the patients were recorded at different stages of pregnancy. Change in MP grade was assessed for those patients, who have delivered vaginally. Results The mean age of the study subjects was 25.77±3.64 years. There was a significant association of MP score with weight gain (P<0.0001) and change in neck circumference (P<0.0001). There was a significant change in the number of patients with MP grade 3 and 4 was noted from first trimester (n=14; 2.26%) to 48 hours post-delivery (n=78; 24.6%) (P<0.01), showing a strong association between change in MP score and pregnancy. Conclusion There was a significant increase in the MP score over the course of pregnancy that may be attributed to gestational weight gain along with variations in the neck circumference in pregnant women. Hence, assessment of MP score is important for proper management of difficult intubation, especially in parturient.

Audit of Eye Care for Ventilated Patients in Intensive Treatment Unit During COVID-19 Pandemic
Authors: Dhanapala Muditha , Sabaretnam Suganya
Published: April 2021

Introduction The protective ocular mechanisms are disrupted due to sedation and neuromuscular relaxants. This increases the risk of developing ocular surface disease (OSD) leading to increased post critical care morbidity. The risks are further increased in patients who are nursed prone as access to eyes is limited. Our aim was to determine whether eye care met the standard of the Ophthalmic Services Guidance and to improve the quality of care provided if found to be deficient. Methodology and Results A prospective audit of the eye care provided to ventilated patients in critical care was done in April, 2020. An ophthalmological examination including fluoresce in staining was done to ascertain the prevalence of ocular morbidity present. Twenty-seven patients met the inclusion criteria and 88% patients were ventilated secondary to COVID-19 pneumonia. 35% of them were nursed prone at time of assessment; 81% had lagophthalmos (incomplete eye closure) while 53% of patients had a variant of OSD, including 23% with swollen conjunctival prolapse, 18% with conjunctivitis and 12% with corneal abrasions. None of the patients with lagophthalmos had received eye lubricants. Of the proned patients 50% had their eyes taped closed but only 33% had eye lubrication applied. We introduced local best practice guidance adapted from the Ophthalmic Services guidance. Education of critical care staff was undertaken and simplified guidance was exhibited in clinical areas. Post-intervention audit was carried out against the standard after a one-month interval and 24 patients were included (80% COVID-19 pneumonia); 67% had eye lubrication and 50% had eyes taped as per guidance in supine position. 100% of proned patients had eye lubricants with micropore taping. Conclusion During the COVID-19 pandemic, staffs were recruited from diverse backgrounds including theatre scrub nurses, recovery practitioners and operation department practitioners, to work alongside critical care nurses caring for ventilated patients. Education on the best ophthalmic practice guidance enabled holistic care to be provided to many ventilated patients by staff with limited prior experience in eye care in critical care.
Importance of Cervical Elongation Assessment for Laparoscopic Sacrocolpopexy
Authors: Onigahara Mikihisa , Yanazume Shintaro , Ushiwaka Takashi , Togami Shinichi , Kamio Masaki , Kobayashi Hiroaki
Published: April 2021

Cervical elongation in patients with pelvic organ prolapse (POP), who previously underwent laparoscopic sacrocolpopexy (LSC), is not fully understood. We report a case of a second surgery for endometrial cancer complicated with POP recurrence, which seemed to be related to cervical elongation following LSC. A 65-year-old woman was referred for invasive treatment following LSC. Although preoperative endometrial cytology was negative, the resected uterine specimen revealed endometrioid carcinoma. The patient also had complications of cervical prolapse with cystocele Stage III. Repeat surgery was performed with a trachelectomy, anterior-posterior colporrhaphy, and vaginal apex suspension. Mesh had been adequately sutured to the upper cervix in the previous surgery, and the resected cervix was elongated up to 9 cm. Cervical elongation may be correlated with the inaccurate preoperative endometrial examination, and it may also promote POP recurrence leading to a poorly supported pelvic floor. We suggest that cervical elongation should be identified before POP surgery.
Measures for Safe Laparoscopic Sacrocolpopexy

Published: April 2021

Laparoscopic sacrocolpopexy is one of the most difficult laparoscopic surgical techniques. In this study, we report on our efforts to safely perform this procedure, which consists of suturing a piece of mesh onto the anterior longitudinal ligament using a nonabsorbent suture during mesh fixation onto the prepromontorium layer, which can lead to massive bleeding if a mistake is made, by performing preoperative and intraoperative image evaluation. Preoperative contrast-enhanced computed tomography was performed. Images in DICOM format were acquired, and three-dimensional vessel reconstruction was performed. After performing a peritoneal incision in the presacral area, ultrasonography was performed using a probe inserted through a 12-mm trocar into the abdominal cavity to re-confirm the absence of vessels near the planned suturing area. After ultrasonography, an Ethibond® suture was inserted through the anterior longitudinal ligament. In our hospital, 126 patients underwent the procedure, and none had a serious hemorrhage or required blood transfusion, indicating the safety of this modified procedure without separation of a wide presacral area. We believe that these techniques can be performed safely with minimal incision. However, we did not examine the efficacy of these techniques in this paper. Further studies are needed to determine whether this approach is suitable.

Published: April 2021

Oculocerebrocutaneous syndrome (OCCS) is a rare disorder with specific clinical presentation. It can be diagnosed clinically upon specific dermatological, neurological, and ophthalmological criterion. We present the case of a 5-week-old baby boy with OCCS syndrome, highlighting its dermatological manifestations and a review of skin features as well. The patient presented with a unilateral microphthalmia with orbital cysts, postauricular crescent-shaped skin defect, and pedunculated skin appendages with multiple focal hypoplastic skin lesions. Early diagnoses and long-term follow-up may improve the prognosis of such a rare disease.
Pachydermodactyly

Published: April 2021

Pachydermodactyly (PDD) is a rare benign form of digital fibromatosis characterized by a progressive painless fusiform swelling of the periarticular soft tissue, surrounding the dorsolateral aspects of the proximal interphalangeal joint. PDD most commonly affects young adolescent males and is frequently unrecognized and misdiagnosed as inflammatory arthritis. In this report, we present a 17-year-old male with a 1-year history of progressive finger swelling in both of his hands diagnosed as PDD. We also highlight PDD's clinical and histologic features with the aim to enhance physician's awareness of this benign condition to cut unnecessary diagnostic tests and interventions.
The predictive ability of SAPS II, APACHE II, SAPS III, and APACHE IV to assess outcome and duration of mechanical ventilation in respiratory intensive care unit
Authors: Dosi Ravi , Jain Gaurav , Jain Nirmal , Pawar Kamendra Singh , Sen Jayeeta
Published: April 2021

Objectives:

The objective is to determine utility of SAPS II, APACHE II, SAPS III, and APACHE IV scoring system in assessing outcome in mechanically ventilated patients in respiratory intensive care unit and to predict duration of mechanical ventilation (MV).

Materials and Methods:

A prospective observational study where 83 mechanically ventilated patients were grouped into Group 1 (n1 = 40, NIV) and Group 2 (n2 = 43, Invasive ventilation) was conducted. SAPS II, APACHE II, SAPS III, and APACHE IV scores based predicted mortality (PM) were collected at day 1, and day 3. Outcomes (on day 7) were grouped into negative and positive. (NIV-negative outcome = Home NIV, intubation or death; positive outcome = NIV free. Invasive group-positive outcome = Extubation; negative outcome = Death). Binary logistic regression was applied to predict duration of MV (> or < 5 days).

Results:

The data were analyzed using SPSS version 17.0 trials comparisons of PM on day 1 with SAPS II (P < 0.05) and APACHE IV (P < 0.007) were significant predictors of clinical outcomes in Group 1 where as in Group 2, none of the system could predict significantly. On day 3, Group 1 analysis revealed SAPS II (P < 0.002), SAPS III (P < 0.03), and APACHE IV (P < 0.004) based PM as significant predictors of outcome. APACHE II (P < 0.05) and APACHE IV (P < 0.02) PM were significant in Group 2. On day 3, APACHE IV could significantly predict (P < 0.05) duration of MV (>5 or < 5) while A-a gradient (P < 0.09) predicted poorly in Group 1. In Group 2, APACHE IV was a poor predictor (P < 0.09). Two full logistic regression models were also formulated for both the groups.

Conclusion:

Study concludes that day 3 severity scores are more significant predictors of outcome and duration. APACHE IV scoring system was found more effective than other systems, not only significantly differentiating outcomes of MV but also predicting duration of NIV.
Safety and Efficacy of Epithelial Island Crosslinking in Keratoconus with Thinnest Pachymetry less than 400µ
Authors: Omar Hisham A. , El-Agha Mohamed-Sameh H. , Hassaballah Mohamed A. , Khalil Noha M.
Published: April 2021

PURPOSE:

To evaluate the efficacy and safety of epithelial-island crosslinking (EI-CXL) in keratoconus with corneas thinner than 400 µm.

METHODS:

Twenty-six patients (30 eyes) underwent EI-CXL (preserving the epithelium over the thinnest area), using standard protocol (3 mW/cm2 for 30 min). Uncorrected and best spectacle-corrected distance visual acuity (UCDVA, BCDVA), manifest refractive spherical equivalent (SEQ), mean simulated keratometry (Kmean), maximum keratometry (Kmax), and thinnest corneal thickness (TCT) were determined preoperatively and at 1, 3, 6, and 12 months following CXL. Endothelial cell count (ECC) was determined preoperatively and at 6 months. Anterior segment optical coherence tomography (AS-OCT) was done at 1 month to determine the depth of the corneal stromal demarcation line (DL).

RESULTS:

After 1 year, mean UCDVA improved from 1.29 preoperatively to 1.17 (P = 0.001) and BCDVA from 0.62 to 0.57 (P = 0.011). Mean manifest SEQ decreased from -7.63 to-7.32D (P = 0.001). Mean Kmean decreased from 54.92 to 54.81D (P = 0.045), and Kmax from 67.60 to 67.42D (P = 0.072), and mean TCT changed minimally from 377.17 to 375.30 µ (P = 0.11). The mean ECC decreased from 2329 to 2268 cells/mm2 (2.6% decrease, P < 0.001). AS-OCT showed a DL in 29 out of 30 eyes at an average depth of 215.9 µ under the spared epithelium, and 299.9 µ in the de-epithelialized cornea.

CONCLUSION:

EI-CXL halted keratoconus progression over a 1-year period. This was associated with statistically significant endothelial loss, but less than seen with conventional epi-off CXL in thinner corneas.

Published: April 2021

The purpose of the study is to evaluate the risk factors associated with exfoliation in a case-cohort setting and literature review. This single-center, prospective, case-cohort study was carried out from January 2010 to April 2020 on patients operated for cataract surgery by a single surgeon in Lebanon. Forty-nine consecutive patients with exfoliation syndrome (XFS) and 62 consecutive control patients were identified and further investigated for selected systemic (diabetes mellitus, systemic hypertension, asthma, or atopy) and ocular variables (baseline vision, severity of nuclear sclerosis, glaucoma, eye rubbing, history of dry eye, or allergic eye disease). The mean baseline Snellen visual acuity was 20/283 in XFS versus 20/145 in control cases (P = 0.012). XFS also demonstrated significantly denser nuclear sclerosis than controls (P = 0.00958). By univariate analysis, allergic conjunctivitis (15 [30.6%] vs. 2 [3.2%]; P < 0.001), dry eye (20 [40.8%] vs. 13 [21.0%]; P = 0.0133), and habitual rubbing of the eyes (33 [67.3%] vs. 19 [30.6%]; P < 0.001) were associated with the presence of XFS. Habitual ocular rubbing was closely associated with allergic conjunctivitis (odds ratio [OR] = 13.0; 95% confidence interval [CI]: 2.8–58.8; P = 0.032). After multivariable analysis, the following variables showed significant results: glaucoma (OR = 34.5; 95% CI: 4.4–250; P = 0.010), duration of surgery (OR = 5.6; 95% CI 2.43–12.9; P < 0.001), and habitual ocular rubbing (OR = 4.42; 95% CI: 1.97–9.90; P = 0.029). This study shows a novel potential correlation between eye rubbing and XFS in a Lebanese cohort. Chronic eye rubbing induces or may exacerbate preexistent zonular damage in subjects with XFS, hence the need to better manage concurrent ocular surface disorder in these patients.
Bilateral Congenital Ptosis Associated with Optic Disc Melanocytoma
Authors: Badawi Abdulrahman H. , Al-Ghadeer Huda
Published: April 2021

We report a rare clinical association of optic disc melanocytoma (ODM) occurring with bilateral congenital ptosis that has not been previously reported. A 28-year-old male patient presented with bilateral congenital ptosis. On examination, his vision was 20/20 in each eye, and dilated fundus examination indicated a pigmented lesion over the left inferior temporal aspect of the optic disc that was consistent with an optic nerve melanocytoma. B-scan ultrasonography indicated a calcified elevated optic nerve head. Bilateral frontalis sling procedures were performed for congenital ptosis with satisfactory results at 1 year postoperatively. There was no progression of the lesion in the left eye. Knowing the key ophthalmoscopic features of an ODM can aid in diagnosing this lesion; ophthalmologists should be familiar with this lesion in addition to the rare association of ptosis. Affected patients should be periodically assessed.
Projection theorems for intermediate dimensions
Authors: Burrell Stuart A. , Falconer Kenneth J. , Fraser Jonathan M.
Published: April 2021

Intermediate dimensions were recently introduced to interpolate between the Hausdorff and box-counting dimensions of fractals. Firstly, we show that these intermediate dimensions may be defined in terms of capacities with respect to certain kernels. Then, relying on this, we show that the intermediate dimensions of the projection of a set

E \subset\mathbb{R}^n

onto almost all

m

-dimensional subspaces depend only on

m

and

E

, that is, they are almost surely independent of the choice of subspace. Our approach is based on that are expressed in terms of capacities. We discuss several applications at the end of the paper, including a surprising result that relates the
box
dimensions of the projections of a set to the
Hausdorff
dimension of the set.

Published: April 2021

Мы рассматриваем работы М. Ш. Бирмана и М. З. Соломяка, касающиеся сингулярных чисел интегральных операторов, с точки зрения современной теории аппроксимации, в частности, используя технику теории всплесков. Мы даем простое доказательство оценок нормы для интегральных операторов с ядром в $B^{1/p-1/2}_{p,p}(\mathbb R,L_2(\mathbb R))$, что одновременно усиливает и проясняет теорему, принадлежащую Бирману и Соломяку. Используя эту же технику, мы даем простой вывод оценок мультипликаторов Шура и двойных операторных интегралов с ограниченным символом из $B^{1/p-1/2}_{2p/(2-p),p}(\mathbb R,L_\infty(\mathbb R))$, распространяя результат Бирмана и Соломяка на символы с некомпактной областью определения.

Published: April 2021

Ghana is rapidly urbanizing. This urbanization has resulted in villages growing into towns and towns into urbanized areas. Theories and models have been employed to explain the internal structure of urban areas, especially, with respect to land use variations. These models started with the classical urban land use models in America. Urban scholars in Africa have struggled to fit the development of the African cities into these classical models. They have therefore called for African scholars to develop models for urban land use in Africa. This paper sought to identify the common patterns of land use activities which shape the internal structure of Ghana’s secondary cities. The study employed Geographic Information System (GIS) as a major tool of analysis in explaining the patterns in urban areas. This is augmented with in-depth ground observations of the study areas. The findings of the study showed the absence of homogeneity in most of the sectors and undefined industrial zones as contradictions to the classical models. The study further revealed that residential zones were not fully occupied by either lower income, middle income, or higher income residence. The income groups may only dominate in a given sector. Based on the findings, a common pattern is proposed to represent the land uses within the selected secondary cities in Ghana.

Improving utilization of conceptual and theoretical framework in nursing research
Authors: Akpabio II
Published: April 2021

The Nursing and Midwifery Councils of many nations including Nigeria and nursing departments of various Universities and institutions have made it mandatory that conceptual and theoretical framework are used to guide Nursing research presented as part of the requirements for the award of certificates and degrees. However, it is often observed that many researchers are not skilled in the use of conceptual and theoretical framework and many do not also utilize conceptual or theoretical framework to guide studies conducted after graduation from their various educational institutions. Others do so for some parts of the research and do not also explain how the framework can be used to guide implementation of the study findings. Additionally, many publishers of research reports do not also demand for inclusion of framework in papers accepted for publication. This paper is aimed at highlighting the importance of using a conceptual framework to guide a study, the criteria that should guide the appraisal and selection of a framework; challenges that can hinder utilization of framework to guide research work and measures of improving utilization of conceptual framework in nursing research.KEYWORDS: Conceptual, Framework, Nursing, Research, Theoretical.

Authors: Abdulkareem KA , Animasaun DA , Oyedeji S , Olabanji OM
Published: April 2021

Characterisation of Sphenostylis stenocarpa (Hochst ex A. Rich) Harms (African yam bean) was carried out to determine the degree of diversity in some accessions in Nigeria. Twelve accessions of S. stenocarpa collected from the International Institute for Tropical Agriculture (IITA), Ibadan, Oyo State, Nigeria, were grown for morphological variability studies in the Screenhouse facility at the Botanical garden, University of Ilorin, Nigeria. Quantitative and qualitative variables were measured 16 weeks after planting. Quantitative data were analysed using Analysis of Variance in SPSS 16.0 for Windows. Cluster analysis was conducted to group the accessions into various cluster groups. Quantitative characters such as length, width and area of terminal leaf, petiole length, number of leaves, number of branches, stem length, and stem diameter were significantly different among the accessions. Variation of leaf colour ranging from pale to deep green exists in the accessions. Stem and petiole pigmentation varied together. Stem girth was different for TSs 162 and TSs 373. Number of branches and leaves distinguishes TSs 138, 152 and 311 from the other accessions. TSs 115, 154 and 163 were morphologically comparable while TSs 41, 125, 139 and 209 had plant height, leaf length, width and area distinguishing them from the other groups. The study concluded that the differences in the accessions of S.stenocarpa could be explored in breeding programme for improved crop.KEYWORDS: African yam bean, breeding, crop improvement, morphological characters, variability.

Published: April 2021

The physical and chemical properties of clay deposits around Isua-Akoko, Akure, Lafe and Ayadi in Ondo State southwestern Nigeria have been examined. The results have shown that Isua-Akoko, Akure and Lafe Clays are plastic fire clays while Ayadi clay is kaolinite. Grain size analysis reveals that Isua Akoko Clay contains 45% of clay, 18% silt, 12% fine sand,14% medium sand and 11% coarse sand and no gravel; Akure clay contains 42% clay, 14% silt, 13% fine sand, 20% medium sand and 8% coarse sand with 1% gravel. Lafe Clay contains 21% clay, 8% silt, 25% fine sand, 37% medium sand and 8% coarse sand with 1% gravel while Ayadi clay contains 83% clay and 17% silt. The liquid limits of these clay samples range from 41% to 73%% and plastic limits range from 18% to 26% respectively. The chemical analysis reveals that the most abundant mineral is silica (60.97%) and aluminum was next in abundance (23.69%) while other oxides are low. The results show that Isua-Akoko and Akure are residual while Lafe and Ayadi are sedimentary and transported Clays. The firing test, PH, and bleaching tests of the clays are also discussed. The chemical and physical characteristics of the clay deposits are strongly indicative of their industrial importance in the production of ceramics, refractories, paving bricks, paint and pharmaceutical products.KEYWORDS: Kaolinite, fire clay, gravel, ceramics and alumina.

Authors: Alhassan UD , Obiora DN , Okeke FN
Published: April 2021

Vertical electrical sounding (VES) was carried out in southern Paiko, north central Nigeria, using Abem Terrameter model SAS 4000. The study area which is about 100km square, falls within the basement complex region of Nigeria with an elevation of 304m above sea level. The study was carried out with a view of determining the subsurface layer parameters (resistivities, depths and thicknesses) that were employed in delineating groundwater potential and sites for structural development of the area. A total of six transverses with ten VES stations along each traverse, having separation of 50m apart, were investigated. It has a maximum current electrode separation (AB/2) of 100m. Three to four distinct geoelectric layers were observed namely; Top layer, weathered layer, fractured layer, and fresh basement layer. Top layer has resistivity, depth and thickness range of 194-4582Ωm, 0.5-47.9m and 0.5-47.9m respectively. Second layer has a range of: resistivity, 11-8475.2Ωm; depth, 1.33-59.6m and thickness, 0.13-55.7m. Third layer has a range of: resistivity, 42.0-9730.9Ωm; the depth and thickness are not defined in some part of the area, while the fourth layer has a resistivity range of 50.2-9145.7Ωm, its depth and thickness are not defined. Eighteen VES stations were delineated as groundwater potentials of the area, having third and fourth layer resistivities ranging from 98Ωm to 309Ωm. Depths range found were from 12.50m to 25.70m and thickness varying between 6.94m and 23.98m. The southeastern and northwestern part of the study area having good aquifer at depths ranging from 21.00m to 26.70m, thickness varying between 18.75m and 55.7m are good sites for location of viable boreholes for potable water. Also the southeast and northwestern parts of the area were delineated for structural development having depths to bedrock varying between 0.63m and 3.99m. Most part of the study area have weak protective capacity, hence are prone to contamination.KEYWORDS: Vertical electrical sounding, groundwater potentials, Southern Paiko, protective capacity, structural development sites, depths to bedrock
Bayesian estimation of simultaneous equation model with lagged endogenous variables and first order serially correlated errors
Authors: Adepoju Adedayo A , Alaba Oluwayemisi O, , Ogundunmadetayo P
Published: April 2021

Most simultaneous equation models involve the inclusion of lagged endogenous and/or exogenous variables and sometimes it may be misleading to assume that the errors are normally distributed when in reality they exhibit functional formsthat are not normal especially in practical situations. The classical methods of estimating parameters of simultaneous equation models are usually affected by the presence of autocorrelation among the error terms. Unfortunately, in practice the form of correlation between the pairs of the random deviates is unknown.In this paper classical and Bayesian methods for the estimation of simultaneous equation model withlagged endogenous variables and first order serially correlated errors are considered. The smallsample properties of the methods at different levels of correlation for ρ = 0.2, 0.5 and 0.8are compared.Better parameter estimates were produced by the Bayesian estimator with smaller standard errors compared to the classical method. The standard deviations of the Bayesian estimator are consistently better than those of the OLS estimator for the sample sizes considered. For example, the standard deviations of the Bayesian for b14 (the coefficient of the lagged endogenous variable,y 1t-1) when ρ = 0.2 at N = 10, 15, 20 and 25 were 0.07712781, 0.05433923, 0.03230012 and 0.03177252 respectively while those of OLS were 0.0784732, 0.4718914, 0.05701936 and 1.31422868. However, when ρ = 0.8, the standard deviations were 0.0548055, 0.03860254, 0.02572899 and 0.02126175 for Bayesian and 0.0562190, 0.03882345, 0.053676 and 0.0315632 for OLS. Interestingly, notice that even at high correlation level, the estimates produced by the Bayesian method are closer to the parameter values and the standard deviations decrease as the sample size increases. Hence, the Bayesian estimation method might be a better choice when lagged endogenous variables are included in a simultaneous equation model with auto-correlated disturbances since it appeared to give better results compared to the classical approach.Keywords: Bayesian estimation, Lagged endogenous variables, Simultaneous equations, Monte-Carlo Simulation, First-order autoregressive process.
