Design of Wheel Chair Up Stairs at Station for Disability People
Authors: Winjaya Fathurrozi , Darmawan Arief
Published: December 2020

Intelligent wheelchairs are motorized resting media designed to help users with physical limitations, where an artificial control system is added or used to replace user controls. The aim is to reduce or eliminate the user's duty to drive a motorized wheelchair. At the station there are still many places that are still not accessible by persons with disabilities. As the difference between platform and train height, usually there are stairs that support to enter the train. Therefore the writer makes an innovation so that it can make it easier for people with disabilities to move up stairs in a wheelchair. The design of the wheelchair design uses a crawler type with the help of universal plates from Tamiya, the gearbox uses Twin Motor with a rotation ratio of 204: 1. Servo motor mounted on the seat which is supported by a gyro sensor as a counterweight to the chair when the position of the chair up or down. In the DC motor and servo PID method is added so that the motion changes can be smooth. PID is installed when testing the equilibrium results obtained a little stable oscillation at Kp = 0.27, Ki = 0.0004, and Kd = 0.0001, while when testing the speed obtained the most stable conditions at Kp = 2, Ki = 1, Kd = 0.25.
Modernization: Etymological, Scientific And Social Philosophical Interpretations
Authors:   Researcher, Tashkent Medical Academy, Uzbekistan, Saidikramovna Umarova Farida
Published: December 2020

In this article analyzed modernization etymological, scientific and social philosophical interpretations. As we know scientific research, by its epistemological basis, requires the identification of concepts and categories that are specific to the object of knowledge, which serve to reveal its ontological nature, and to have a clear idea about them. As science undergoes a process of deep integration, it is natural for concepts and categories to shift from one discipline to another, especially in the field of philosophy. Philosophy's tendency to be universal, comprehensive, and prone to extensive approaches give rise to concepts and categories related to specific sciences (physics, medicine, biology, mathematics, etc.). This sometimes leads not only to general notions of concepts and categories, but also to different notions from the original etymological interpretation. As a result, a single word is interpreted differently, resulting in assumptions that do not correspond to the ontological features of the object of study. In order for such “word games” not to occur, in order to have a clear idea of the object of research, scientific research begins with defining the concepts and categories that express the object and purpose of research, and defining their essence and functional functions. Such a fundamental concept, category, is "modernization" for our scientific research.
Towards 3D self-assembled rolled multiwall carbon nanotube structures by spontaneous peel off
Authors: Quinson Jonathan
Published: December 2020

Controlling the 3D assembly of individual nanomaterials can be a challenging task. However, it opens up opportunities for the production of increasingly complex nanostructures. Unusual rolled multiwall carbon nanotube structures are synthesized here by simply inducing a change of precursor composition during the growth of multiwall carbon nanotube forests. The multiwall carbon nanotube structures are comprised of nitrogen-doped and undoped sections, and are obtained via a detailed peel off and roll mechanism. These results open new doors for the development of increasingly complex nanostructures.
MEDIA REFERENSI BERBASIS TEKNOLOGI FACEBOOK BAGI WARTAWAN DALAM MENYUSUN BERITA
Authors: Setiyaningsih Lian Agustina , Fahmi Muhammad Hanif , Sawidodo Fitrataqwin
Published: December 2020

Facebook memiliki fungsi beragam termasuk dalam membantu kegiatan profesional. Sebagai media sosial yang digunakan oleh 140 juta penduduk Indonesia, facebook memiliki peran signifikan juga dalam membantu tugas wartawan. Fenomena pemanfaatan referensi media sosial juga banyak dipraktikkan di luar negeri. Namun, konvergensi media mempertanyakan batasan pemanfaatan facebook oleh wartawan dalam menyusun berita. Sebab, konvergensi media memberikan keleluasaan bagi pengguna media sosial untuk bisa menjadi komunikan sekaligus komunikator di dalamnya. Penelitian ini menggunakan metode naratif kualitatif yang mewawancarai 9 informan terdiri dari wartawan cetak, elektronik maupun online. Metode naratif menggambarkan praktik penggunaan sumber media facebook dari kaca mata wartawan yang dijadikan sebagai sumber dalam menyajikan berita. Purposive sampling merupakan teknik pengambilan jumlah informan. Hasil dari penelitian ini adalah facebook dijadikan sebagai media referensi oleh wartawan dalam mencari, menggelola dan menyusun berita. Batasan penggunaan referensi ada pada kegiatan mencari obyek pemberitaan dan memperkuat data penulisan berita. Terdapat dua fitur dalam facebook yang dijadikan sebagai referensi yakni update status dan grup. Wartawan berperan sebagai gatekeeper dalam mendistribusikan pesan. Langkah yang dilakukan dalam mengelola  informasi berita di facebook meliputi: pengecekan, filter, crosscheck dan penulisan berita. Sedangkan, kriteria informasi yang diakses adalah bobot informasi berdampak sosial, proximity, kecenderungan media tentang konten pemberitaan, keunikan konten, extraordinary, nilai dan berita yang tinggi.
La prudence du juge à l'épreuve des organisations judiciaires
Authors: Danet Jean
Published: December 2020

En quoi l'organisation judiciaire, appréhendée au travers de la procédure suivie en amont de l'audience, de ce qui reste de celle-ci, du service du juge, du déroulement de sa carrière et enfin de l'évolution du management, pèse-t-elle sur l'office prudentiel du juge civil et pénal ? C'est la question que cet article explore. Sans aucunement mythifier le passé, il en ressort que les évolutions analysées tout comme diverses inerties propres à l'institution entravent l'office prudentiel du juge au risque d'en faire le simple débiteur d'une décision.
Les pères analyseurs de l’institution familiale contemporaine ?
Authors: Bessaoud-Alonso Patricia , Clément Juliette
Published: December 2020

L’institution familiale s’est transformée ces dernières décennies à la faveur d’un processus assujetti à un arsenal législatif, aux mutations sociétales et aux politiques publiques mises en œuvre. L’individualisme prend corps au sein de la famille avec une expression du désir exacerbé autour de la parentalité et plus singulièrement de la paternité. L’institution est revisitée à travers la place du père, biologique ou non, quelles que soient la configuration familiale et l’orientation sexuelle. Les pères sont-ils des analyseurs des familles contemporaines ?
Paradoxes (inter)institutionnels et clinique de l’action : le cas du service social scolaire d’une collectivité territoriale
Authors: Garcia Gilles , Rougerie Corinne , Fugier Pascal , Lyet Philippe
Published: December 2020

Une recherche-intervention conduite par une équipe de quatre chercheurs au sein du service social scolaire d’une ville française permet d’interroger les paradoxes institutionnels de l’intervention de ce service qui ne peut se déployer que par une forme d’invisibilisation de ses activités et modes opératoires tout en en pâtissant. La posture professionnelle que les travailleurs sociaux scolaires ( tss ) adoptent auprès de leurs partenaires institutionnels s’inscrit dans une logique d’action clinique, relevant d’une posture du « prendre soin », à travers laquelle le tss est à l’écoute de leurs expériences vécues et éprouvées. Certains mouvements défensifs ou offensifs ont été repérés dans des instances du dispositif de recherche à mesure que celui-ci s’est déployé. Cette démarche vient déranger l’organisation de travail et les vécus des acteurs de terrain et produit du changement par des jeux de pouvoirs qui échappent aux chercheurs.
Quand l’équipe fait bloc. Contenance ou violence institutionnelle ?
Authors: Chapellon Sébastien
Published: December 2020

Dans les structures éducatives ou médico-sociales, on relève parfois l’existence d’un écart entre la pratique quotidienne des acteurs et la mission que l’institution s’est assignée. Confrontés à différents registres de violence, vécue et/ou subie, les professionnels s’adaptent à travers des pratiques à visée défensive, ceci dans le but de survivre. L’usager est alors conçu comme un ennemi dont il importe essentiellement de se protéger. Cet article explore les tenants et les aboutissants de cette situation en étudiant comment les professionnels peuvent inconsciemment se souder contre l’usager. Les contextes institutionnels présentés permettent de comprendre pourquoi certaines institutions peinent à accueillir le public avec souplesse et sensibilité.
Institution scolaire et idéologie inclusive
Authors: Cassagne Jean-Marie
Published: December 2020

Le volontarisme politique actuel en faveur de l’école inclusive s’inscrit dans le prolongement d’un mouvement par lequel les institutions subordonnent leur fonctionnement à des énoncés idéologiques. Dans le contexte de la formation des enseignants, l’irruption du paradigme inclusif interroge les présupposés à partir desquels les professionnels de terrain envisagent leur action au quotidien, notamment dans le cadre du travail en équipe. Prenant pour point de départ les problématiques auxquelles les enseignants se confrontent dans le cadre de l’accompagnement d’élèves désignés comme ayant des besoins éducatifs particuliers, la présente contribution propose une analyse socio-historique des idéologies scolaires distinctes – et souvent contradictoires – à partir desquelles la situation de ces élèves tend à être appréhendée dans le contexte d’un système scolaire se caractérisant par une forte différenciation structurale.
Vers une redéfinition anthropologique du sujet de l’aide dans les pratiques d’accompagnement social ?
Authors: Blondel Frédéric
Published: December 2020

L’article se propose d’examiner, à partir de l’étude comparée de deux périodes (1945-2000 ; 2000 à nos jours), les inflexions que subit la relation d’aide sociale dans le champ de l’accompagnement des personnes vulnérables. Ces inflexions sont liées à des transformations rapides dans les champs politico-économiques, socio-organisationnels et enfin dans le champ des disciplines mobilisées pour penser les capacités d’autonomisation des demandeurs d’aide sociale. Deux conceptions de la relation d’aide sont étudiées. La première, d’inspiration psychosociologique, conçoit l’autonomie comme un projet à accompagner ; la seconde, d’inspiration comportementaliste et cognitiviste, conçoit l’autonomie comme réalisée et c’est à la levée de ce qui l’entrave que s’attache alors l’accompagnement.
Règles pénales et administratives de la lutte anticorruption : l’influence des normes étrangères et internationales
Authors: Jaune Renaud
Published: December 2020

La loi n o  2016-1691 du 9 décembre 2016 relative à la transparence, à la lutte contre la corruption et à la modernisation de la vie économique, dite « Sapin 2 » comporte des innovations importantes inspirées des normes et pratiques étrangères, notamment américaines. Ainsi, la compétence extraterritoriale du juge pénal est renforcée et un nouveau mécanisme de transaction est introduit. En outre, des règles de conformité nouvelles sont imposées aux grandes entreprises et aux personnes publiques, sous le contrôle de l’Agence française anticorruption, également créée par la loi. Ceci étant, la législation française ne se limite pas à une transposition du référentiel anticorruption international : elle lui ajoute au contraire une composante préventive originale.
Des dispositifs évolutifs pour la prévention et la répression de la corruption
Authors: Gamgani Lisa , de Tonnac Aurélia
Published: December 2020

Les dispositifs de lutte contre la corruption ont connu de nombreuses évolutions en France, depuis les années 1980. Celles-ci sont souvent le résultat de facteurs d’influence internes et externes de nature très diverse, tels que l’élaboration de normes internationales ou les scandales politico-financiers. Elles sont également le signe d’un approfondissement de la logique préventive dans la stratégie de lutte contre la corruption mise en œuvre par le législateur français.
L’administration de projet : pérenniser le provisoire et l’agilité dans les structures publiques
Authors: Kerléo Jean-François
Published: December 2020

L’administration de projet renouvelle les modes de management en supprimant des strates hiérarchiques, en assouplissant le fonctionnement en silo et en incitant les agents, par de nombreux appels à projets, à innover par la création de nouveaux produits et services. Cette administration s’organise autour de chefs de projet et d’équipes pluridisciplinaires recrutés à titre temporaire et dispose de leviers financiers tels que le Fonds pour la transformation de l’action publique. Au-delà de la méthode managériale, l’administration de projet se caractérise par la création d’un cadre juridique, la suppression d’échelons hiérarchiques et un ensemble de dispositifs qui tentent de pérenniser des processus de réalisation d’activités inédites et innovantes. L’enjeu est alors d’inscrire durablement dans l’architecture administrative un fonctionnement reposant sur des activités transversales et provisoires.
On $ \sigma $-self-orthogonal constacyclic codes over $ \mathbb F_{p^m}+u\mathbb F_{p^m} $
Authors: Liu Hongwei , Liu Jingge
Published: December 2020

In this paper, we generalize the notion of self-orthogonal codes to \begin{document}$ \sigma $\end{document}-self-orthogonal codes over an arbitrary finite ring. Then, we study the \begin{document}$ \sigma $\end{document}-self-orthogonality of constacyclic codes of length \begin{document}$ p^s $\end{document} over the finite commutative chain ring \begin{document}$ \mathbb F_{p^m} + u \mathbb F_{p^m} $\end{document}, where \begin{document}$ p $\end{document} is a prime, \begin{document}$ u^2 = 0 $\end{document} and \begin{document}$ \sigma $\end{document} is an arbitrary ring automorphism of \begin{document}$ \mathbb F_{p^m} + u \mathbb F_{p^m} $\end{document}. We characterize the structure of \begin{document}$ \sigma $\end{document}-dual code of a \begin{document}$ \lambda $\end{document}-constacyclic code of length \begin{document}$ p^s $\end{document} over \begin{document}$ \mathbb F_{p^m} + u \mathbb F_{p^m} $\end{document}. Further, the necessary and sufficient conditions for a \begin{document}$ \lambda $\end{document}-constacyclic code to be \begin{document}$ \sigma $\end{document}-self-orthogonal are provided. In particular, we determine all \begin{document}$ \sigma $\end{document}-self-dual constacyclic codes of length \begin{document}$ p^s $\end{document} over \begin{document}$ \mathbb F_{p^m} + u \mathbb F_{p^m} $\end{document}. In the end of this paper, when \begin{document}$ p $\end{document} is an odd prime, we extend the results to constacyclic codes of length \begin{document}$ 2 p^s $\end{document}.
A generalization on derivations of Lie algebras
Authors: Chang Hongliang , Chen Yin , Zhang Runxuan
Published: December 2020

We initiate a study on a range of new generalized derivations of finite-dimensional Lie algebras over an algebraically closed field of characteristic zero. This new generalization of derivations has an analogue in the theory of associative prime rings and unites many well-known generalized derivations that have already appeared extensively in the study of Lie algebras and other nonassociative algebras. After exploiting fundamental properties, we introduce and analyze their interiors, especially focusing on the rationality of the corresponding Hilbert series. Applying techniques in computational ideal theory we develop an approach to explicitly compute these new generalized derivations for the three-dimensional special linear Lie algebra over the complex field.
A four-field mixed finite element method for Biot's consolidation problems
Authors: Qi Wenya , Seshaiyer Padmanabhan , Wang Junping
Published: December 2020

This article presents a four-field mixed finite element method for Biot's consolidation problems, where the four fields include the displacement, total stress, flux and pressure for the porous medium component of the modeling system. The mixed finite element method involving Raviart-Thomas element is used for the fluid flow equation, while the Crank-Nicolson scheme is employed for the time discretization. The main contribution of this work is the derivation of the optimal order error estimates for semi-discrete and fully-discrete schemes for the unknowns in energy norm or $ L^2 $ norm. Numerical experiments are presented to validate the theoretical results.
Efficient computations for linear feedback control problems for target velocity matching of Navier-Stokes flows via POD and LSTM-ROM
Authors: Lee Hyung-Chun
Published: December 2020

An efficient computing method for a target velocity tracking problem of fluid flows is considered. We first adopts the Lagrange multipliers method to obtain the optimality system, and then designs a simple and effective feedback control law based on the relationship between the control $ {{\boldsymbol f}} $ and the adjoint variable $ {{\boldsymbol w}} $ in the optimality system. We consider a reduced order modeling (ROM) of this problem for real-time computing. In order to improve the existing ROM method, the deep learning technique, which is currently being actively researched, is applied. We review previous research results and some computational results are presented.

La sombra blanca de Casarás: génesis, fuentes y tradición de la ¿primera? novela fantástica sobre el Temple en España
Authors: Huertas Morales Antonio
Published: December 2020

Hasta la fecha, La sombra blanca de Casarás, de Jesús de Aragón y Soldado, publicada por primera vez en 1931, había llamado la atención de la crítica sobre todo por la labor de su autor en la composición de La torre de los siete jorobados, con la que mantiene una evidente deuda. Las presentes páginas pretenden constituirse como el primer estudio dedicado exclusivamente a la obra y, a través del análisis de la presencia de la Orden del Temple en la misma, demostrar que, aun tomando elementos de Emilio Carrère, Jesús de Aragón escribió la primera novela española fantástica sobre los conmilitones Christi, originalidad especialmente relevante por el signo diabólico que adquieren sus magos-soldados.
La guerra de Vietnam en la poesía española
Authors: Neira Julio
Published: December 2020

A mediados de la década de 1960, en pleno debate dentro de la lírica española entre el mantenimiento del compromiso político y social de la poesía y la búsqueda de nuevas poéticas por parte de una nueva promoción de autores nacidos después de la guerra civil, un tema concita la unanimidad de todo el ámbito poético: la guerra de Vietnam. Poetas de todas las edades, ideologías, estéticas y lenguas peninsulares se implicaron en la denuncia de las atrocidades de aquella guerra imperialista que conmocionó a todas las sociedades occidentales y muy especialmente la española, que concibió la protesta como una forma más de lucha contra la dictadura del general Franco, firmemente apoyada por los Estados Unidos de América. En el presente artículo se reúne un abundante corpus de poemas que abordaron esa temática.
Vivimos en una noche oscura ou la voi(e)x de la révolte chez César Muñoz Arconada
Authors: Le Bigot Claude
Published: December 2020

L’étude de Vivimos en una noche oscura de César Arconada (1898-1964), recueil publié en 1936, non réédité à ce jour, entend mettre en lumière l’originalité d’une écriture qui est à la fois dénonciation et dés-occultation des mécanismes socio-économiques qui ont assujetti les prolétaires à la domination des maîtres. Les antagonismes de la lutte des classes nourrissent une vision prophétique de l’émancipation des travailleurs. En mettant en œuvre une rhétorique de combat, l’auteur rejoint la cohorte des poètes engagés dans la lutte antifasciste. Mais Arconada n’adopte pas pour autant le style de la poésie prolétarienne. En choisissant le verset, il donne à son discours un souffle épique inédit, soucieux de rapprocher révolution langagière et progressisme social.

Corps, désirs et plaisirs : expériences de résistance de femmes trans* incarcérées dans une prison pour hommes à Mexico
Authors: Constant Chloé
Published: December 2020

Parmi les 3 000 personnes catégorisées comme « hommes » et incarcérées à la Penitenciaria de Mexico, une vingtaine se reconnaissent comme « femmes ». Le système carcéral ne se contente pas de discipliner et punir des sujets présumés ou reconnus coupables, mais il en construit de nouveaux qui doivent correspondre aux normes sociales sexo-génériques. Cet article analyse les formes de résistance des femmes trans* incarcérées comme des performativités exercées face aux économies morales de la prison et au « dispositif carcéral de la sexualité » (dont l’article propose une définition), à partir de l’examen des pratiques corporelles, des désirs et des plaisirs.

Published: December 2020

Objective: To investigate the incidence of diabetic cystopathy in relation to age, gender, type of diabetes, duration of diabetic disease and clinical evidence of peripheral neuropathy and to analyze the physiopathology of the various forms of diabetic cystopathy due to sensory impairment, motor-sensory impairment, motor impairment and hyperreflexia. Materials and methods: In a retrospective multicenter cohort study the medical records of a cohort of 126 diabetic patients with (128 patients) or without (48 patients) urological symptoms were analyzed. Patients were observed at the Città di Alessandria Clinic of Policlinico di Monza and/or at the outpatient clinic of Alessandria Hospital from June 2018 to June 2020. The study excluded patients with central and/or peripheral neuropathy, spina bifida (mylomeningocele or meningocele) or spina bifida occulta; with persistent urinary infections; in anticholinergic treatment for enteric dysfunctions; in medical treatment for cervical-prostatic-urethral obstruction; with vaginal and/or rectal prolapse of II, III, IV degree; with previous spinal or pelvic surgery including radical prostatectomy, Wertheim hysterectomy or colorectal surgery. All the patients were studied with computed tomography (CT) scan of the urinary tract, voiding cystourethrography (VCUG), uroflowmetry, cystomanometry with intrinsic pressure assessment and compliance evaluation, electromyography (EMG) of the anal sphincter, pressure flow analysis, urethral pressure profile and, when advised, pharmacological tests.Results: Out of 126 diabetic patients, 48 did not show any signs or symptoms of urine voiding dysfunction; 30 were men and 18 women with an average age of 62.6 years; 20 had type I diabetes and were in treatment with insulin and 28 type II diabetes treated with oral hypoglycemic medication. The remaining 78 patients (48 men and 30 women), with an average age of 64.8 years, presented urological symptoms; 31 had type I diabetes and 47 had II type diabetes. Conclusions: Diagnosis of the various forms of diabetic cystopathy and early treatment decreases complications and consequently accesses to outpatient facilities and hospital admissions, resulting in an improved quality of life.
Ventricular Septal Defect: Echocardiography Evaluation
Authors: Tripathi Ravi Ranjan
Published: December 2020

Ventricular septal defects (VSDs) are among the most common congenital heart defects. These defects may be isolated, associated with other defects, or occur as an intrinsic component of some complex heart defects. There is wide variation in size and location of VSD. Echocardiography plays an important role in evaluation of anatomy, hemodynamic significance, and planning of management of VSDs. With the emerging trends in transcatheter closure of VSD, echocardiography plays a crucial role in decision-making and intra- and postprocedure evaluation. A stepwise approach of echocardiography is necessary for accurate evaluation and management of VSDs.
Echocardiographic Approach to Congenitally Corrected Transposition
Authors: Chaudhuri Maitri , Tomar Munesh
Published: December 2020

The hallmark of corrected transposition is discordance at atrio-ventricular and ventriculo-arterial level and that is defined as “double discordance”. This can occur as an isolated anomaly but more commonly has associated defects; most common being ventricular septal defect followed by tricuspid valve abnormalities. Other associated defects are pulmonary stenosis, systemic and pulmonary venous anomalies, univentricular physiology, ventricular dysfunction (morphological right ventricle facing systemic circulation) and association of conduction abnormalities. Echocardiography plays a pivotal role in defining the anatomy and planning the management. In this article we are discussing about role of echocardiography in evaluation of corrected transposition, diagnosing the lesion, role in immediate post-operative period and on follow up.
Impact of Mitral Valve Replacement on the Right Ventricle Function in Mitral Stenosis
Authors: Swaminathan N. , Sangareddi Venkatesan S. , Ravishankar G. , Paul Justin , Binny L. Alen
Published: December 2020

Background:

In patients with mitral stenosis (MS), right ventricular (RV) function may be altered due to an increase in the left atrial pressure and/or changes in pulmonary arteriolar vasculature or may be affected by rheumatic process directly.

Aims:

In this study we have evaluated the recovery of RV function upto 3 months in patients undergoing mitral valve replacement (MVR) using two dimensional and tissue Doppler echocardiographic indices (TDI).

Materials and Methods:

A total of 30 patients who were advised MVR were enrolled prospectively. All patients underwent MVR successfully. RV function was assessed using conventional and TDI pre-operatively, 1 week, and 3 months after surgery.

Results:

New York Heart Association (NYHA) functional class improved significantly at the end of one week. Mean transmitral gradient reduced postoperatively. Tricuspid regurgitation severity reduced significantly. Significant RV reverse remodelling was noted at the end of 3 months. Global RV function parameters fractional area change and RV Tei index improved significantly at the end of 3 months. In patients with mild to moderate pulmonary hypertension (PH), global RV function improved significantly, RV remodelling was seen. In patients with severe PH, both global and longitudinal functions did not improve at the end of 3 months follow up, though RV remodelling was noticed.

Conclusion:

In patients with severe rheumatic MS whenever per-cutaneous trans-mitral commissurotomy is not feasible, MVR promotes RV remodelling and improvement in RV function along with significant improvement in NYHA functional status. But this improvement in RV function was noted only in patients with mild to moderate PH rather than in patients with severe PH.

Comparing the association of cardiovascular nursing care with blood pressure and length of stay of in-patients with coronary artery disease in Wuhan, China
Authors: B Ramadhani Fatina , Liu Yilan , Jing Xue , Qing Ye , Xiong Han , Zhang Fengjian , Wei Pian
Published: December 2020

Background: Coronary artery disease is a leading cause of morbidity and mortality worldwide. Comorbidity-like hyperten- sion has been among the major risks of coronary artery disease. Recent evidence identified multiple benefits of cardiovas- cular nursing care to coronary patients. However, little has been appraised on benefits regarding patients’ blood pressure control and length of hospitalisation.

Objective: To compare the association of cardiovascular nursing care delivered to coronary artery patients with patients’ blood pressure and length of stay.

Methods: Records based retrospective design was applied at a large teaching hospital in Wuhan, China. SPSS 21 version was used for data entry and analysis with univariate and multivariate logistic regression models for comparing study variables.

Results: Of 300 patients, 224 (74.7%) were known to be hypertensive and admitted with subnormal blood pressure. Cardiovascular nursing care like “assess to grade pain severity on 1-10 scale” and “counsel patient to cope with stress” were six and three times more likely to contribute improved patients’ blood pressure (AOR=5.8; 95%CI: 2.8-12.2, p=0.001) and (AOR=3.1; 95%CI: 1.2-7.8, p=0.015) respectively. No significant difference with length of stay (p>0.05).

Conclusion: There is a possibility of coronary artery patients to recover with normal blood pressure following reception of evidence-based cardiovascular nursing care.

Keywords: Cardiovascular nursing care; blood pressure; in-patients; coronary artery; Wuhan; China.

Management of spinal-induced hypotension for elective caesarean section: A survey of practices among anesthesiologists from a developing country
Authors: Ismail Samina , Sohaib Muhammad , Farrukh Fatima
Published: December 2020

Background: In developing countries, more than half of the anesthesia-related maternal deaths are related to spinal hypo- tension.

Objective: To explore the practices of management of spinal induced hypotension with respect to fluid and vasopressor administration among anesthesiologists from a developing country.

Methods: After approval from institutional ethics committee, an online questionnaire was sent to anesthesiologists reg- istered with Pakistan Society of Anesthesiologists between July and August 2018 to determine management strategies for prevention and treatment of spinal-induced hypotension.

Results: The response rate was 36% (156/433), majority from academic institution (62.8%) with equal representation from attending and trainee anesthesiologist. For prophylaxis 39.1% respondents did not use vasopressors, 32.7% used fluid preloading with crystalloids (54.7%) as fluid of choice followed by combination of co-loading and vasopressor(22.4%). Phenylephrine was the vasopressor of choice for both prophylaxis (33.1%) and treatment (57%). Attending anesthesiologist used a combination of fluid co-loading and vasopressors for prophylaxis as compared to trainee anesthesiologists (37.2% vs. 17.9%; P=0.035) and selected vasopressors according to patient’s heart rate (33.3% vs. 19.5%; p=0.05). Prophylactic phenylephrine was used more by respondents from the academic institution (p=0.023). Fluid co-loading was used more by respondents with <30 % compared to those with > 30% of clinical responsibility to obstetric anesthesia (P<0.05).

Conclusion: Phenylephrine as the vasopressor of choice indicates growing awareness of management strategies among anesthesiologists from developing countries but there is a need to increase its use for prophylaxis. Some variation in practice according to the level of anesthesiologist, practice type and responsibilities to obstetric anesthesia are evident.

Published: December 2020

Background: The purpose of this study is to evaluate the impact of menopause on sexual function in women and their spouses.

Methods: This is a cross-sectional study that was conducted from January 2018 to May 2019 in Rasht (North of Iran). The participants included 215 menopausal women and their spouses. Data were collected using the demographic questionnaire, the Female Sexual Function Index (FSFI) questionnaire, and the International Index of Erectile Function (IIEF) question- naire.

Results: On the basis of the FSFI and IIEF scores, 36.28% (78/215) women reported female sexual dysfunction (FSD) and 17.2% (37/215) men reported erectile dysfunction (ED) with 8.37% (N = 18) being mild, 5.58% (N = 12) mild to moderate, and 3.25% (N = 7) moderate ED. After adjusting differences in the female age distribution, the total score and scores of the IIEF subscales were also not significantly lower in the spouses of women with FSD than women without FSD.

Conclusion: Although, significant correlations between male erectile function and menopausal female sexual function have not identified; but, low scores of the subscales of FSFI in female participants mostly impaired sexual satisfaction and overall satisfaction in their spouses.

INTRODUCTION
Emicizumab (Hemlibra®, Hoffmann-La Roche, Switzerland) is now available for haemophilia A patients with or without factor VIII inhibitors. Management of bleeding events and replacement therapy for invasive procedures have to be adapted.

OBJECTIVE
To provide a practical guidance for the management of breakthrough bleeding events and elective or urgent surgery in adult and paediatric patients with haemophilia A without inhibitors treated with emicizumab.

METHODS
Based on the available literature and the experiences collected from adult and paediatric patients treated in Switzerland, the Working Party on Haemostasis of the Swiss Society of Haematology and the Swiss Haemophilia Network worked together to reach a consensus on the management of bleeding events and invasive procedures.

RESULTS AND CONCLUSION
Minor bleeding events and invasive procedures associated with low bleeding risk can be treated without factor replacement therapy in most cases, whereas major bleeding events and high-risk surgery require additional factor VIII replacement at usual doses, at least for the first days. Emicizumab treatment should be continued throughout the procedure and during the postoperative period. Elective major surgery should be planned according to emicizumab dosing for patients with a once-a-month posology. Of note, so far only few data are available on the management of major bleeds and surgery in patients with haemophilia A treated with emicizumab and this practical guidance will have to be regularly updated with growing experience.

Abstract

Various kinds of collaborative learning can be applied in teaching English. One of them is a partner reading strategy which allows the students to read in pairs. This research aimed at exploring the significant enhancement of partner reading strategy on the eighth-grade students` reading habit and their reading comprehension. The quasi-experimental design was used in order to gather the data and the two classes were selected through cluster random sampling as the experimental and control group. The independent sample t-test result indicated that the comparison of students` reading habit and reading comprehension in the experimental and control group with sig. (2-tailed) or p-value (0.00) was less than the alpha value (0.05). It can be concluded that the use of partner reading strategy significantly enhanced the eighth-grade students` reading habit and their reading comprehension. The partner reading strategy made the teaching and learning process more joyful and meaningful so that it can be applied as one of the activities to promote reading habit and reading comprehension.

Published: December 2020

Knowledge discovery is also known as Data mining in databases, in recent years that technique plays a major role in research area. Data mining in healthcare domain has noteworthy usage in real world. The mining method can enable the healthcare field for the enhancement of institutionalization of its administrations and become quicker with best in class technologies. Innovation utilization isn't restricted to basic leadership in undertakings, yet spread to different social statuses in all fields. In this paper a novel approach for the detection of brain tumor is proposed. The novel approach uses the classification technique of K-nearest neighbor (KNN) and for ignoring the error of the dataset image SOM (self-organizing map) algorithm has been used. Discrete wavelet transform (DWT) is used for transforming input image data set, in which RGB color of input data image has been converted into gray scale. Then it has been classified using KNN after that the error avoiding algorithm has been carried out. This will help to differentiate tumor cells and the normal cells. The presence of tumor in brain image is detected using parametric analysis by simulation.
A Compact Gradient Based Neural Network for Capon Spectral Estimation

Published: December 2020

This paper describes the use of a novel gradient based recurrent neural network to perform Capon spectral estimation. Nowadays, in the fastest algorithm proposed by Marple et al., the computational burden still remains significant in the calculation of the autoregressive (AR) Parameters. In this paper we propose to use a gradient based neural network to compute the AR parameters by solving the Yule-Walker equations. Furthermore, to reduce the complexity of the neural network architecture, the weights matrixinputs vector product is performed efficiently using the fast Fourier transform. Simulation results show that proposed neural network and its simplified architecture lead to the same results as the original method which prove the correctness of the proposed scheme.

Published: December 2020

Bu çalışmada, mevcut üretim hatlarında kullanılan konvensiyonel bir presin tasarımı incelenmiştir. Konvansiyonel preslerde gerekli pompa büyüklüğünü geri dönüş debisi ihtiyacının belirlediği sonucuna varılmıştır. Bazı durumlarda geri dönüş için gerekli motor gücünün de iş için gerekli motor gücününden daha büyük olduğu görülmüştür. Buradan yola çıkılarak, sisteme hidrolik veya pnömatik balans (dengeleme) silindirleri eklenerek geri dönüşte hidrolik silindirlere etki eden ağırlıklar azaltılmış, mevcut sistemdeki geridönüş hızının da arttırılması hedeflenmişir. Yapılan çalışmada parça üretim sayısı artarken bir çevrimdeki enerji sarfiyatı da düşmüştür.

Published: December 2020

O objetivo deste trabalho foi diagnosticar os principais aspectos de saúde ambiental na UNIBOL Guaraní, Bolívia. Para tanto recorreu-se a técnica de observação participante, além da realização de entrevistas e aplicação de questionários. Também foi realizada uma coleta e análise de uma amostra de água nas dependências da instituição. Na área de recursos florestais identificou-se que as principais pressões ambientais estavam associadas ao desmatamento e a pecuária; como potencialidade foram identificados estudos com viveiro e captura de carbono realizados na universidade. Verificou-se que a água para consumo humano está contaminada por coliformes totais além do limite permitido na norma nacional. Sobre os resíduos sólidos observou-se a ausência de um Plano de Gestão de Resíduos Sólidos e consequente descarte inadequado. A avaliação dos estudantes sobre os aspectos ambientais foi negativa para a questão dos resíduos sólidos, porém foi positiva para a água, a qualidade do ar e do ruído. Conclui-se que, apesar de ter um projeto inovador de educação, a UNIBOL precisa ter um olhar mais voltado aos aspectos da saúde ambiental.
Guerras híbridas e Fake News: a escalada da autoverdade

Published: December 2020

Neste manuscrito apresentamos como as Fake News são empregadas como um artifício das Guerras Híbridas funcionando como ataques precisos para a desestabilização de bases conceituais, políticas ou até mesmo enfraquecendo lideranças e Estados, fomentando a desestabilizações e/ou crises nos seus alvos. Desta forma, visamos chamar atenção para uma clara intenção de grupos específicos aceder o poder e realizar a dominação social ao buscar o controle sobre aspectos intangíveis, tais como sociedade, ideologia, psicologia e informação, e além disso como a massa crítica é usada contra as autoridades e introduz o desafio que o movimento busca de confrontar publicamente o Estado e tentar derrubá-lo.
