تَأثير إستخدام المالية الحَديثة كأداة لتقييم الأداء المالي والاستمرارية وفق معيار التَدقيق الدولي رقم (570)
Authors: Rzgar Ahmed Ramyar
Published: August 2022

هدفت هذه الدراسة إلى إبراز إمكانية إستخدام المؤشرات المالية الحديثة في تقييم الأداء المالي للوحدة الاقتصادية والقدرة على الإستمرار في نشاطها مستقبلاً، حيث تم تسليط الضوء على الأدوات الإحصائية الحديثة منها على المنهج الكمي التحليلي التمييزي الخطي مُتعدد المتغيرات (MAD) وبتحديد أنموذجي (Altman Z-score) و (Sherrord)، والتي تم إسقاطها على القوائم المالية للوحدة، لإعطاء أرقام ونتائج قابلة للتحليل، بغية معرفة الوضعية المالية السائدة في الوحدة الإقتصادية، والتنبؤ بما سيكون عليه هذا الوضع مستقبلا، وتحديد مختلف الاختلالات التي قد تؤدي بالوحدة إلى الإفلاس لأتخاذ القرارات المناسبة والإجراءات التصحيحية ان لزم الأمر.
كما تهدف الدراسة إلى إبراز مسؤولية مراقب الحسابات وفقاً لمعايير التدقيق الدولية وإبراز دور مراقب الحسابات وأهميته عند إعطاء الرأي حول إستمرارية الوَحدة الاقتصادية بإعتماده على المؤشرات المالية الحَديثة للتحليل المالي لأجل الحُكم على قدرة الوَحدة في المُستقبل بالإستمرار، والكشف عن المخاطر المالية المحتملة التي تؤدي إلى الفشل المالي والإفلاس، وكذلك تحديد أهمية التنبؤ به، بالإضافة إلى إجراءات التدقيق الرئيسة المتبعة في التنبؤ بالمخاطر المالية ومدى التزام مراقب الحسابات بمسؤوليته وفق معيار التدقيق الدولي رقم (570). لتحقيق أهدافها، حيث تعمل على تقييم أداء أنشطة الوحدة الإقتصادية المختلفة المحاسبية والمالية والتشغيلية، مما جعل التدقيق الخارجي يلعب دوراً مهماً في مساعدة إدارة الوحدة في مسؤولياته المختلفة وإتخاذ القرارات المناسبة وإجراءات تصحيحية لتجنب الإفلاس.
ومن أهم النتائج التي توصل اليها الباحث أن المؤشرات المالية الحديثة المستخدمة في التحليل تعتبر أداة تساعد مراقب الحسابات والمحللون الماليون لتقييم الأداء المالي ومعرفة مدى قدرة الوحدة الإقتصادية على الإستمرار في المستقبل المنظور. كما يُمكن الإعتماد على المؤشرات المالية الحديثة للكَشف عن نُقاط القوة والضُعف والتنبؤات بالمخاطر المالية المستقبلية للوحدة الاقتصادية من خلال عملية تحليل، بما في ذلك إتخاذ القرار والإجراءات التصحيحية.
ويوصى الباحث بضرورة إستخدام مؤشرات مالية حديثة لدعم معيار التدقيق الدولي رقم (570) للتدقيق ومعرفة مدى ملاءمة فرض الاستمرارية في الوحدات الاقتصادية، لتمكين إداراتها من التنبؤ بمستقبل الوحدات بشكل دوري. ومن خلاله تستطيع الإدارة تحديد المقومات والصعوبات التي تواجه إستمراريتها في المستقبل ومعالجة الصعوبات التي تواجهها.

Published: August 2022

One of the most common health care problems globally is COVID-19, and also there are an international effort to monitor it have been proposed and discussed. Despite the fact that many studies have been performed based on clinical evidence and confirmed infected cases. However, there is room for additional research since a range of complex criteria are included for later research forecast. As a consequence, mathematical modelling mixed with the numerical simulations is an effective method for estimating main propagation parameters and forecasting disease model dynamics. We study and present some models for the COVID-19 in this paper, which can answer significant questions concerning global health care and implement important notes. The IMEX Runge–Kutta and classical Runge–Kutta methods are two well-known computational schemes to find the solution for such system of differential equations. The results, which are based on these numerical procedures suggested and provide estimated solutions, provide critical answers to this global problem. The amount of recovered, infected, susceptible, and quarantined people in the expectation can be estimated using numerical data. The findings could also aid international efforts to increase prevention and strengthen intervention programs.  The findings could also support international efforts to increase prevention and strengthen intervention programs. It is clearly that the proposed methods more accurate and works in a very large interval in time with a few step sizes. That is consequently beginning to a decrease in the computational price of the method. Numerical experiments show that there is a good argument and accurate solutions for solving this type of problem.

Shoulder Ornaments in the local version of the Moksha Women's Costume.
Authors: Shigurova Tat'yana Alekseevna
Published: August 2022

The article fills in the missing knowledge in science about the shoulder element of the kavlalks (armpits) of the traditional women's costume of the mid-nineteenth century of the villages of Levzha, Perkhlyai, Suzgarye of the Insarsky district of the Penza province, presents a complete description of its constructive and decorative specifics and the names of the details of the decoration in comparison with similar elements in the Mordovian costume and in comparison with the correspondences in the costumes of the peoples of the Middle Volga region. The materials of the archive of the Russian Geographical Society (hereinafter referred to as the SBI "RGO") are investigated as the main sources. Along with general scientific methods, systematic, comparative-historical and art criticism approaches were also used. The novelty of the work is due to the study of the original decoration of the local version of Moksha clothing, previously not mentioned by researchers. It is established that the existence of the shoulder decoration until the middle of the nineteenth century reflects the complex ethnogenetic processes in the Oka-Sur interfluve of the XVI – XVIII centuries. The technical, technological, artistic and stylistic features of the element of the Moksha women's costume reveal an affinity with the decoration of the ozhanuchka, preserved until the twentieth century in the Erzya women's costume of the Temnikovsky district of the Tambov province. The scientific contribution is determined by enriching the classification of Mordovian costume jewelry with a unique variant of the strap-type decor, known only to the Mordovian people.

Artificial intelligence in healthcare: Should it be included in the medical curriculum? A students’ perspective
Authors: BANSAL MANISHI , JINDAL ANKUSH
Published: August 2022

The application of artificial intelligence (AI) in healthcare has increased due to rapid digitization and integration of computer science in all fields. However, the outcome in relation to patient treatment and healthcare delivery is not that visible. The reasons could be non-availability of data, lack of computerization and financial constraints. Besides this, the lack of appropriate teaching at undergraduate level about AI and its medical applications could be an obstacle. Including AI in medical school curriculum and collaboration with faculties of computer science can augment the knowledge of medical students about AI at the graduate level for better application in the real world. This will help the medical profession to prepare their younger fraternity for the future in AI.
The rationale and guiding principles to design a psychiatry curriculum for primary care doctors of India
Authors: DINAKARAN DAMODHARAN , MANJUNATHA NARAYANA , KUMAR CHANNAVEERACHARI NAVEEN , MATH SURESH BADA , THIRTHALLI JAGADISHA
Published: August 2022

Background

Integrating psychiatric care into the general practice of primary care doctors (PCDs) is necessary to overcome the shortage of human resources to cater to the burgeoning public mental health needs of India. The traditional psychiatry curriculum is often top–down and specialist-based that contributes little in terms of skill quotient. We designed an innovative, digitally driven, distance education-based, part-time, modular-based Primary Care Psychiatry Programme (PCPP, skill-based). It is being implemented across many states of India to equip PCDs with skills to provide first-line psychiatry treatment. We discuss the rationale and guiding principles behind designing the curriculum of PCPP.

Discussion

There are nine guiding principles behind designing and implementing PCPP to provide pragmatic, acceptable, feasible modules of higher translational quotient (TQ) that are essential to upskill PCDs. There is a shift in training the location of PCDs in their live brief general consultations utilizing innovative telemedicine-based ‘on-consultation training’ (OCT) augmented with collaborative video consultations. A monolithic treatment protocol-driven, trans-diagnostic approach is used to design a concise, all-inone, point-of-care manual containing a culturally sensitive, rapid, validated screener and taxonomy, called ‘Clinical Schedules for Primary Care Psychiatry’. This incorporates the PCDs’ style of clinical practice that helps in picking up the most commonly prevalent adult psychiatric disorders presenting to primary care.

Conclusion

This PCPP curriculum contains pragmatic modules with higher TQ. This curriculum is dynamic as the learning is bi-directional. This can be used by policy-makers, innovators and academia for integration with national health programmes such as those for non-communicable diseases and reproductive and child health.
Preoperative cardiology referral practices at a tertiary care centre: A retrospective observational study
Authors: PAVITHRAN PRIYANKA , ARAYULLATHIL BINESH
Published: August 2022

Background

Preoperative consultations and testing add to healthcare costs. Unnecessary consultations lead to further testing and delay in surgery. Guidelines help us in clinical practice but are seldom followed. We studied the appropriateness of our preoperative cardiology referrals according to the guidelines and functional utility of the consultations.

Methods

We reviewed the records of patients who underwent elective non-cardiac surgery to identify those who had a preoperative cardiology consult. Appropriateness of the referral was assessed by comparing with the 2014 American College of Cardiology/American Heart Association guidelines. Any recommendations made, major adverse cardiac events and perioperative outcome were also noted.

Results

Only 71 (15.5%) referrals were appropriate according to the guidelines. A majority of them were for preoperative clearance. The most common recommendation was to withhold antiplatelet medications. None of the consultations made any change in the anaesthetic or surgical plan. Six patients had major perioperative adverse cardiac events.

Conclusion

The majority of consultations were by surgeons and were not indicated according to the guidelines and did not have any impact on patient outcome. A large proportion of these patients had low cardiac risk index. As anaesthesiologists, we are best equipped to quantify risk and optimize a patient and should be the leaders of the perioperative period.
National exit test: The medical faculty perspective—A pilot study
Authors: DULLOO PUJA , KANITKAR MADHURI
Published: August 2022

Background

Implementation of the exit examination for medical graduates in India has been debated for many years. The national exit test (NEXT), under the construct of the National Medical Commission Act, would serve two purposes: first, it will be a common exit/licentiate examination for all Indian medical graduates, and second, it will be a test for postgraduate selections for all specialties. There has been no research or evidence on stakeholders’ opinion on this test. We aimed to assess the perspective of medical faculties, nationwide, regarding the implementation of NEXT.

Methods

We conducted a nationwide, cross-sectional, questionnaire-based pilot survey. The Google survey form with close- and open-ended questions was forwarded via email and WhatsApp to various groups.

Results

Two hundred and forty-five medical teachers participated, of which 35.9% were from Gujarat, 44.9% were working in government colleges, 91.43% had MD/MS as the highest professional degree, 50% had >15 years of experience and were from different medical specialties. The majority felt that the NEXT examination was a positive step, 82.5% suggested that a national selection/testing authority should conduct it, 36.3% suggested having the test after internship while 32.7% expected some weightage for each year of the medical programme, and 84.1% agreed that all the learning domains should be assessed by various strategies.

Discussion

Faculties welcomed the NEXT examination under a national testing authority. The necessity of this examination is to have uniform standards and quality for medical graduates irrespective of their institutes. Assessment of all the domains will make the Indian medical graduate more competent for the job or residency programmes.

Published: August 2022

The discovery of novel antibacterials devoid of cross resistance is of utmost importance. At the same time, biological pathways and processes suitable to be targeted are limited. At Actelion Pharmaceuticals we decided to work on novel bacterial topoisomerase inhibitors (NBTI) to discover new antibiotics with broad spectrum activity and limited resistance development for use against severe hospital infections. This paper summarizes the learnings and results of our efforts in the field, which led to the discovery of multiple chemical classes with potent Gram-negative activity and ultimately to the selection of several compounds that underwent preclinical profiling.
Stable Isotope Analysis of Greenhouse Gases Requires Analyte Preconcentration

Published: August 2022

Nitrous oxide (N2O) is an important trace gas contributing to global warming and depletion of ozone in the stratosphere. Its increasing abundance is caused mainly by anthropogenic sources, such as application of fertilizers in agriculture or emissions from industry. To understand the N2O global budget, its sources and sinks need to be well-described and quantified. In this project, a new method for N2O source appointment was developed that can help with this task. The method is based on analysis of the eight most abundant isotopic molecules of N2O, using quantum cascade laser absorption spectroscopy (QCLAS). The applicability of the method towards the N2O biogeochemical cycle was demonstrated on a prominent N2O source (bacterial denitrification) and the most important N2O sink (UV photolysis) on samples prepared in laboratory experiments. An extension of the QCLAS method to natural samples can be achieved by hyphenation with a preconcentration technique that increases concentration of the analyte and standardizes the sample matrix. This article provides an overview of currently applied preconcentration techniques in the field of greenhouse-gas analysis and a description of the preconcentration device TREX that will be employed in future projects with the developed QCLAS method.
A universal synthesis protocol for tuneable metal-organic framework nanohybrid
Authors: Zhang Wei , Bojdys Michael , Pinna Nicola
Published: August 2022

Metal-organic frameworks (MOFs) with encapsulated functional nanoparticles (NPs) enjoy a vastly expanded application potential in catalysis, filtration, and sensing. In general, diffusion-controlled infiltration and metal ion-based strategies that force heterogeneous nucleation have yielded piecemeal, partial successes in overcoming the lattice mismatch between the MOF-shells and NP-cores. To this date, however, no universally applicable synthesis for MOF-nanohybrids emerged that covers the full diversity of all possible core-shell combinations. Here, we show a versatile, general synthesis protocol using a representative set of seven MOF-shells (ZIF-zni, ZIF-8, ZIF-67, FJU-30, MIL-88(Fe), HKUST-1, and MOF-74(Co)) and six NP-cores (Ag, Au, NaYF4, β-FeOOH, Fe2O3 and Ni3[Fe(CN)6]2) that are fine-tuned to incorporate from single to hundreds of cores in mono-, bi-, tri- and quaternary composites. Our key strategy is to regulate the rate of diffusion of alkaline vapours that deprotonate the organic building blocks and trigger the controlled MOF-growth and encapsulation of NP-cores. This strategy is expected to pave the way for the exploration of sophisticated MOF-nanohybrids that draws from the full range of hitherto known MOF-architectures and core-compositions.
On the Fly Determination of the Substrate Activation in Hydrolases Using a Neural Network
Authors: Khrenova Maria , Krivitskaya Alexandra , Nemukhin Alexander
Published: August 2022

Active sites of enzymes are able to activate substrates and perform chemical reactions that cannot occur in solutions. We focus here on hydrolysis reactions catalyzed by enzymes and initiated by the nucleophilic attack of the carbonyl carbon atom of the substrate. From the electronic structure standpoint, substrate activation can be characterized in terms of the Laplacian of the electron density. This is a simple and easily visible imaging that allows one to “visualize” electrophilic site on the carbonyl carbon atom, that is presented only in the activated species. The efficiency of the substrate activation by the enzyme can be quantified from the ratio of reactive and nonreactive states from the QM/MM MD trajectories. We propose a neural network that assigns the Laplacian of electron density maps to the reactive and nonreactive species. The neural network is trained on the cysteine protease enzyme-substrate complexes and successfully validated on the zinc-containing hydrolase, thus showing a wide range of applications of the proposed approach.

Thiadiazoles are a privileged motif in medicinal chemistry, however selective mono-oxidation of the endocyclic sulfur, without over oxidation, is challenging. Herein, we report the quantitative conversion of 1,2,6-thiadiazines to 1,2,5-thiadiazole 1-oxides in the presence of visible light and molecular oxygen under ambient conditions. Experimental and computational studies reveal a probable mechanistic pathway for the cycloaddition-ring contraction cascade: under visible light irradiation in the presence of molecular oxygen, 1,2,6-thiadiazines act as triplet photosensitisers that produce singlet oxygen and subsequently undergo an unprecedented, chemoselective [3 + 2] cycloaddition reaction. The resulting endoperoxide undergoes a ring contraction, with selective carbon atom excision and complete atom economy. The reaction was optimised under both batch and continuous-flow conditions and proven to be efficient in wide range of solvents, including green solvents. Flow conditions enabled precise control over irradiance exposure, enabling exclusive access to photosensitive thiadiazole products. A comprehensive scope of 1,2,6-thiadiazines provided 35 examples of novel, difficult-to-access 1,2,5-thiadiazole 1-oxide structures.

Authors:   , Hyland Matthew Luke
Published: August 2022

In the ever-growing debate over climate change and the importance of the environment, greenspaces are being ripped down in the name of modernity. For this reason, a part of the greenspace at Rock Creek Park is being removed to make way for a new Metro Line. The impending construction will remove several trees from its route and replace them with a light rail system. Before this could happen, this study examined the trees within Rock Creek Park using LiDAR data, to locate and identify the trees and the size of the canopy that covers the area. By identifying trees that will be removed from the route residents will be better informed of the impact that the new Metro Line will have on their greenspace.

En el presente artículo se clasificara como ocupacionales y no ocupacionales, diferenciación elementos que puede ayudar a realizar un diagnóstico diferencial entre aquellos trabajadores sin factores predisponentes a padecer una lesión crónica acumulativa y que acontece por una previsible relación con su trabajo, de aquellos otros en los que del resultado de una adecuada anamnesis se detecte una base individual que predisponga a una determinada patología. La Bursitis, se denomina aquel dolor originado de la bursa, o saco sinovial, que es una estructura anatómica a modo de colchón que amortigua la fricción entre los diferentes huesos que coinciden en el hombro. Anatómicamente, se describen varias bursas dentro del hombro. Existe otra estructura anatómica importante que es causa frecuente de dolor, denominada manguito rotador, que es un conjunto de 4 tendones que permiten los ángulos principales de movilidad del hombro. El síndrome del túnel carpiano es una dolencia provocada por la inflamación y la presión en el interior del túnel formado por huesos (carpo) y un ligamento (ligamento carpiano transverso) en la muñeca. Por el túnel carpiano discurren diversos tendones y el nervio mediano. La cirugía mínimamente invasiva es una buena opción para los pacientes que padecen una hernia discal o estenosis espinal en una sola vértebra. En el caso de pacientes que necesitan cirugía en varias vértebras o una operación más compleja, la cirugía abierta tradicional puede ser la mejor opción más conveniente. La higiene del trabajo tiene un carácter preventivo, cuyo objetivo es la salud y el confort del trabajador, evita que se enferme o ausente. Se aplicó una metodología descriptiva, con un enfoque documental, es decir, revisar fuentes disponibles en la red, con contenido oportuno y relevante para dar respuesta a lo tratado en el presente artículo.

La dermatitis atópica es una afección crónica, recurrente, no contagiosa, inflamatoria y pruriginosa de la piel, que ocurre con mayor frecuencia en niños, pero también en muchos adultos. Hay estudios recientes en los que, además de dejar en evidencia la complejidad de esta patología, se destaca la importante influencia que ejercen la conjugación de varios factores que le desencadenan, tales como: factores genéticos, factores ambientales, factores inmunológicos, disfunción de la barrera cutánea. El objeto del presente estudio bibliográfico es el de revisar la literatura científica y académica disponible y vigente, con la cual se pueda exponer sobre la Dermatitis Atópica, definiciones, prevalencia, fisiopatología, diagnóstico, tratamiento y prevención y recomendaciones. En los resultados se presentan los distintos criterios expertos como evidencia de haber alcanzado el objetivo planteado. Finalmente se deduce que, la dermatitis atópica es muy frecuente en la infancia y tiene tendencia a cronificar sino se diagnostica y trata precozmente.

La salud mental ha sido un problema invisibilizado a nivel mundial durante décadas, especialmente la correcta aplicación de medidas de seguridad, a personas con trastorno y enfermedad mental como consecuencia jurídica de un acto típico y antijurídico cometido por una persona inimputable. Este ensayo tuvo como objetivo principal analizar, de manera dogmática jurídica, la respuesta del sistema penal ecuatoriano ante la inimputabilidad del autor de un delito cuando padece enfermedad mental. Como puntos principales se abordaron el diagnóstico y las falencias tanto normativas como técnicas en relación con el tema de estudio, concluyendo que la incorporación de la medida de seguridad a la legislación ecuatoriana significó un gran avance en cuanto a la relación entre el proceso penal y la salud mental de los infractores. Sin embargo, pese a que ya son ocho años desde la promulgación del Código Orgánico Integral Penal, no ha existido un perfeccionamiento de esta institución penal.

El objetivo principal del tratamiento interceptivo es minimizar la extensión del desarrollo de maloclusión a modo de abordar los factores psicosociales. Este tipo de tratamiento es aplicado desde temprana edad para la corrección de la mordida y guiar los huesos maxilares tanto inferiores como superiores. El programa sistemático de interceptación comienza con un tratamiento de ortodoncia de fase primaria y mixta, en esta fase el tratamiento con ortodoncia es efectivo. Aunque una segunda fase del tratamiento puede ser requerido en la mayoría de los casos, los procedimientos interceptivos pueden producir resultados y reducir la gravedad de la maloclusión, lo que garantiza a corrección temprana en la mordida del niño e incrementa el bienestar social y psicológico antes de la adolescencia. Hoy en día existen numerosos procedimientos interceptivos que se incluyen en los programas de salud pública para reducir la carga de maclusion en las poblaciones desatendidas y como estrategia para aumentar el acceso al tratamiento de ortodoncia cuando los recursos son limitados. Mediante el desarrollo de este proceso investigativo, se exponen varias posibilidades de intercepción en la dentición primaria.
