Published: March 2023

It is unknown that the novel Coronavirus (COVID-19), which emerged for the first time in December 2019 and spread all over the world, have affected how many children symptomatically or asymptomatically. The uncertainty of the treatment algorithm of pandemic factor and rapidly developing pandemic process created a chaotic environment in whole world. Children and adolescents have been adversely affected by this chaotic environment. Studies examining the effects of this period on the mental health of children and adolescents are scarce. It has been suggested that individuals with psychiatric disorders such as attention deficit-hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) adapted more difficultly and were affected more negatively than other individuals. In this study, we present a patient with ADHD and oppositional defiant disorder (ODD) who was using short-acting methylphenidate (IRISMPH) for treatment, had no worsening or any adverse side effects and was treated carefully for COVID-19 infection. However, further studies are required to evaluate the safety of IRIS-MPH and other psychotropic agents in patients with COVID-19.

Objective: Sleep-related breathing disorders (SRBD) as obstructive apnea, central apnea, and Cheyne-Stokes respiration (CSR), can be seen in patients with chronic heart failure. SRBD can influence the prognosis of heart failure. We aim to reveal sleep-related breathing disorders in heart failure patients and display the effects of adaptive servo-ventilation (ASV) as a new therapeutic modality.
Materials and Methods: In this prospective study, 32 patients with heart failure were included. One night polysomnography (PSG) was done.
Results: According to the results of PSG, the SRBD ratio was 96.7%. Continuous positive airway pressure (CPAP) and ASV titrations were offered to all patients with an apnea-hypopnea index (AHI) > 5. Demographics, clinical properties, symptoms, PSG findings, Cheyne-Stokes respiration (CSR), and echocardiography results were recorded. Before and after ASV titration, pulmonary function tests and walking tests were performed, and concentrations of transferrin and pro-BNP were recorded. In the groups according to the AHI, severe obstructive sleep apnea syndrome (OSAS) in 18 of 30 patients, four moderate OSAS, five mild OSAS, and two central sleep apnea (CSA). PSG and, CPAP, ASV titrations were done in 7 male and one female patient that obstructive apnea, central apnea, AHI, arousal, and SpO2 min values had significant improvements (p=0,001, p=0,016, p=0,001, p=0,015 and p=0,008 respectively). We determined all CSRs were eliminated with ASV. After ASV titration pro-BNP, walking distance, and FVC values changed significantly (p=0,036, p=0,018, and p=0,018 respectively).
Conclusion: As a result, we determined CSR and central apneas persisted with CPAP but were eliminated with a one-night ASV application. ASV also decreased pro-BNP and increased FVC and walking distance values significantly.

Calcineurin inhibitors (CNIs) are a significant component of the immunosuppressive regimen after kidney transplantation. By inhibiting cytokine gene transcription, CNIs suppress T cell and T cell-dependent B cell activation. Tacrolimus is preferred in most patients undergoing kidney transplantation. Thrombotic microangiopathy (TMA) is a severe but rare complication of CNIs therapy. TMA defines a specific pathologic lesion of arterioles and capillaries that leads to microvascular thrombosis. A 45-year-old male underwent kidney transplantation five months ago due to autosomal dominant polycystic kidney disease (ADPKD). His triple-maintenance immunosuppressive therapy includes tacrolimus. Abdominal pain and bloody diarrhea occurred in the fifth month of posttransplant. The edematous and erythematous mucosa of the ascending colon was detected on the colonoscopy. The foci of microthrombi inside the vessel lumen in the lamina propria were shown biopsy. The thrombosis or occlusion was excluded with computerized tomography (CT) angiography in abdominal vessels. The fragmented red blood cells and moderate thrombocytopenia were detected on the peripheral blood smear. Eventually, TMA diagnosis was established through laboratory and histological findings. Tacrolimus was suspected as the trigger of the pathological process and promptly switched to the everolimus. Afterward, laboratory abnormalities and clinical symptoms were improved. In this case, we intend to emphasize drug-associated TMA and atypical presentations, such as colonic microvasculature involvement.

Population growth and industrial demand are related in construction of buildings and houses which contribute to increment of energy consumption. The invention of phase change materials (PCMs) with high latent heat capacity were explored to be integrated into building materials. PCMs are substances that are capable of storing large amounts of thermal energy as latent heat during their phase transition. Development of this product can ensure a comfortable indoor temperature in buildings without depending on air conditioning system which consumes more energy and damage the environment not to mention contributing towards global climate change. This research concentrated on proposing the method of PCM incorporation and its heat resistance performance. Calcium Chloride Hexahydrate (CaCl2.6H2O) was used in this research while the incorporation method is direct mixing into gloss paint and added into zip-lock plastic then covered by conventional cement plaster. From the data obtained, we can see the PCM incorporated wall is better in heat resistance than wall without PCM resulting difference in temperature between internal and external wall 3 ˚C rather than 1 ˚C. For the conclusion , PCM incorporated wall can decrease the internal temperature of building slightly contributing to conserving nature by reducing air conditioner system consumption.

Perovskite solar cells based on lead halide has demonstrated the fast increase in efficiency and advanced in photovoltaic technology in the last decade. However, perovskite solar cells that contain lead (Pb) has high efficiency but tangible risk to humans, animals, and the environment. Bismuth oxyiodide (BiOI) has been recognized as a suitable candidate of non-toxic material to replace lead without adversely impacting performance in perovskite solar cells. The interest in application of BiOI thin films is because BiOI has narrow band gap, high efficiency light absorption and high photo catalytic activity makes it the perfect contender to replace Pb as new non-toxic material perovskite solar cell. Thin films of BiOI were synthesized and deposited using Successive Ionic Layer Adsorption and Reaction (SILAR) on glass substrates. The same mole ratios of bismuth(III) nitrate pentahydrate (Bi(NO3).5H2O) and potassium iodide (KI) were diluted in deionized water to achieve clear solution. The microscope glass was dipped consecutively in 0.01M of (BiNO3)2.5H2O diluted in deionized water, 0.01M of (KI) diluted deionized water and in 50 ml deionized water. This process has been repeated for 30 times and finally the sample was dripped and dried in air. The sample was annealed at various annealing temperature from 250 °C, 350 °C, 450 °C, and 550 °C for 20 minutes. The optical properties and structural properties of BiOI thin films were characterized using X-ray powder diffraction (XRD), Ultraviolet-visible (UV-Vis) measurement and Field Emission Scanning Electron Microscope (FESEM). The Surface Profilometer (SP) was used to measure the thin films thickness. The structure of the films changed with the annealling temperature. The color of the film changes to the orange-yellow and become more yellowish with increasing annealing temperature. The morphology of FESEM images demonstrated that the BiOI thin films have flakes morphology structure with the size around 1μm. The deposited film thickness ranged between 3.479 µm and 8.082 µm. This study provided significant output and a pathway for non-toxic BiOI thin film for perovskite solar cells.

Slope failure is a natural disaster that involves the movement of ground and rock under the influence of gravity. There are several factors influencing slope stability, including the excessive surcharge load imposed on the top of the slope. This study performs slope stability analysis to evaluate the performance of a non-homogenous man-made slope constructed on the UPNM campus. The methodology of this research comprises two parts. The first part is laboratory test, and the second part is simulation work. The laboratory tests conducted to determine the soil properties are sieve analysis, permeability test, and direct shear test. The limit equilibrium method using the SlopeW software is employed to determine the effect of imposing a gradually increasing surcharge load on the man-made slope from a varying distance. The value of Factor of Safety (FOS) and critical slip surface formation obtained using SlopeW were used to determine the maximum load carrying-capacity before failure. The results showed that the FOS decreased with an increasing surcharge load. However, the FOS increased as the distance of the load increase. Further analysis was carried out to enhance the stability of the slope. By reducing 40% of slope height, the stability of slope is increased to 44%. It is also suggested that no activity or development should be carried out on the slope crest to prevent slope failure occurrence in the future.

Small-scale electronic devices require long hours’ operation and fast charging time. Potential technology to support requirement of small-scale electronic device is micro scale combustor. Unfortunately, micro scale combustion is prone to combustion instability. Therefore, objective of this study is to investigate the combustion characteristics, mechanism that stabilize the flame and combustor performance of the 2-D microchannel combustor with bluff body having various slit percentages gap. Two-dimensional computational domain with the height and length of the channel H = 1 mm and L = 16 mm is used respectively. The height of the bluff body is 0.5 mm and located at 2 mm from the inlet. The slit gap percentage varied in this study is 0% to 70%. The results show that the combustion characteristic such as stable flame, wavy flame, blow-off, and flame split into two parts is significantly influenced by the slit gap percentage. Flame is moving downstream and blow-off at the slit percentage of 10% to 25%. At the slit percentage of 30%, the flame zone moves towards the upstream due to the secondary vortex that exists behind the bluff body as slit gap increases and pushes the flame upstream. The reaction zone is split into two parts at 60% and 70% slit gap percentage. It is due to the incoming fresh mixture of CH4/air mixture flows through the slit and cuts the flame zone. It is also found that by increasing inlet velocity beyond 2.0 m/s, the flame becomes unstable and leads to blow-off as increase in equivalence ratio up to 1.0.

Different types of image acquisition devices render different measure of colour depending on the specification of devices; even a same device will give different values of colours rendered, taking at certain duration of times. Most of the researches nowadays have attempted to solve these limitations and the researches of colour correction algorithm has been evolved recently. Colour correction algorithm has been widely used in various fields such as food industry, medical imaging, forensic cyber applications, film industries etc. In medical imaging, researchers have considered colour correction as an essential part in their pre-processing step prior to diagnosis. There are various statistical methods in colour correction and colour grading algorithm being implemented nowadays and finding the best algorithm with high accuracy is non-trivial. This paper presents comparative analyses of colour correction techniques that combine colour correction and colour grading algorithm using conventional gamma correction, polynomial regression, and proposed polynomial regression with modified gamma Look-up Table (pgLUT). It has been observed that our proposed pgLUT colour correction algorithm outperformed the conventional methods by 16.5%.

Introduction. Previous data suggest that healthcare students, such as nursing students, might have a differential risk of presenting burnout syndrome caused by the stress they are subjected to. However, the evidence is still scarce and inconclusive. Objective. To evaluate the association between nursing training and burnout syndrome among undergraduate students in Hidalgo, Mexico. Method. A cross-sectional analytical study was conducted on 566 undergraduate students (56% were nursing students and the rest were non-healthcare students). Burnout syndrome was identified using the Spanish version of the Maslach Burnout Inventory-Student Survey, consisting of subscales: emotional exhaustion, depersonalization, and diminished academic efficacy. The association between the variables of interest was evaluated using logistic regression models adjusted for confounders. Results. In the depersonalization subscale, nursing students, compared with non-healthcare students, had an adjusted Odds Ratio (aOR) of moderate/high burnout syndrome of 2.08 (95% confidence interval [CI] = [1.34, 3.22]). In addition, the association was stronger among students in the third and fourth school years (aOR = 3.58; 95% CI = [1.62, 7.89]) compared with those in the first and second school years (aOR = 1.20; 95% CI = [.71, 2.03]). Discussion and conclusion. It is necessary that universities provide nursing students with tools that allow them to cope with stressful situations during their academic training and their future life as health professionals.

The purpose of the study is to analyze the study of the river basin systems of the left tributaries of the Dniester, located within the Ternopil region of Ukraine. Information is provided regarding previously made generalizations regarding the study of the rivers of the basin from the works of the 19th century. to modern monographic publications and individual articles. The study of the first publications summarizing the regime of the rivers of the basin and their use shows that it was the needs of shipping that determined the beginning (in the middle of the 19th century) of regular observations of water levels on the Dniester, when the first four water measuring posts were opened. The first water measuring posts on the left-bank tributaries of the Dniester within the region were opened during the times of Austria-Hungary – in the 80s and 90s of the 19th century. Measurement of water consumption at individual stations began at the beginning of the 20th century. Since the end of the 80s of the last century, the number of posts on the Podil tributaries of the Dniester within Ternopil Oblast has remained unchanged and amounts to 11 units. A significant drawback of stationary hydrometric observations within the basin for the period from their beginning to the middle of the 20th century. there is an interruption in the series of observations at almost all posts, since a significant part of the materials of observations at posts that worked within the boundaries of the former Austro-Hungarian (before the First World War), Polish and Romanian parts of the basin in the interwar period (20-30s of the XX century. ) turned out to be lost. The analysis of the state of study of the rivers of the region and their basins shows that the greatest attention in the works of domestic scientists is devoted to the analysis of various aspects of the hydrological regime of the rivers of the region. Research on the hydrochemical regime and water quality, the hydroecological component, attracted much less attention.

Son yüzyılda akıllı makine ve robotlardan işletmelerde birçok alanda oldukça fazla yararlanılmaya başlanmış olup, bu alanlardan birisi de vergi uygulamalarıdır. Akıllı makine ve robot kullanımının artmasıyla beraber bunların hangi alanlarda etkin bir şekilde kullanılabileceği ve insanoğlunun hayatını kolaylaştıracağı bilim insanları tarafından araştırma konusu olmuş ve olmaya devam etmektedir. Bu bağlamda işletmelerde artan dijital dönüşüm yapay zekâ kavramını da gündeme getirmiştir. Yapay zekânın insana özgü birçok özelliği taklit etmesinden hareketle, bu çalışmada işletmelerde artan yapay zekâ uygulamalarının vergi uygulamalarında kullanılması vergi mükellefleri tarafından nasıl algılanır sorusuna Ağrı ve Afyonkarahisar illerinde yaşayan 21 vergi mükellefi ile mülakat yapılarak cevap aranmıştır. Araştırmaya katılan vergi mükelleflerinin vergi uygulamalarında yapay zekâyı kullanmak istedikleri ve Ağrı ilindeki vergi mükelleflerinin, Afyonkarahisar ilindeki vergi mükelleflerine göre daha fazla bilgi sahibi olduğu, insan kaynakları açısından vergi dairesinin personel istihdam politikasını olumsuz olarak etkileyebileceği tespit edilmiştir. Bu çalışmanın vergiyle ilgili kurumlara, işletmelere ve paydaşlara yapay zekâ teknolojisini etkin ve verimli bir şekilde kullanılmasının, inovasyon yatırımlarına ağırlık vermesi açısından yol gösterebileceği ve literatüre katkı sunabileceği düşünülmektedir.

Authors: KÖSE Onur
Published: March 2023

Çalışmanın temel amacı, Avrupa’nın Tahran Konferansı sürecindeki jeopolitik ağırlığını ölçülebilir hale getirmektir. 28 Kasım 1943’ten 1 Aralık 1943’e kadar liderler ve üst düzey kurmaylar arasında dört günde toplam on dokuz kez görüşme yapılmıştır. Jeopolitik ağırlığı tespit etmek için bu görüşmeler üzerinden üç yöntem geliştirilmiştir. Birinci yöntemde görüşmeler içerisinde tartışılan ana coğrafi bölgeler tespit edilmiş ve yüzde belirlenmiştir. İkinci yöntem olarak tutanaklarda coğrafi bölgelerin isminin kaç kez geçtiği tespit edilip bu veriler için de yüzde belirlenmiştir. Üçüncü yöntem ise konferans sonunda alınan kararlardır. Birinci yöntem genel analizin %40’ını, ikinci yöntem genel analizin %40’ını, son yöntem de genel analizin %20’sini oluşturmuştur. Üç analiz yöntemi birleştirildiğinde Tahran Konferansı’ndaki coğrafi ağırlık yüzdesi belirlenmiş ve ağırlık merkezleri harita üzerinde gösterilmiştir. Çalışmadaki bulgulara bakıldığında Tahran Konferansı’nda tartışılan konuların, Avrupa’daki mevcut çatışma bölgeleriyle tam anlamıyla örtüşmediği görülmüştür. Bu konferansta Türkiye’nin jeopolitik ağırlığı, kendisi gibi savaş dışı kalmayı tercih etmiş ülkelerden çok daha fazla olmuştur. Konferansta ön plana çıkan konular; Türkiye’nin savaşa girmesi ve Overlord Harekâtı’dır. Bunun yanında Almanya da görüşmelerde sıklıkla tartışılmıştır.

Every day, the number of newly confirmed cases of coronavirus (COVID-19) rises in many countries. It is critical to adjust policies and plans in order to investigate the relationships between the distributions of the spread of this virus in other countries. During this study, the intuitionistic fuzzy c-means (IFCM) clustering method is used to compare and cluster the distributions of COVID-19 spread in 62 countries. Using the IFCM clustering algorithm, the study aims to cluster the countries that use environmental, economic, social, health, and related measurements that affect disease spread to implement policies that regulate disease spread. As a result, countries that have similar factors can take proactive measures to address the pandemic. The data are obtained for 62 countries, and six different feature variables (factors associated with the spread of COVID-19) are determined. The data are obtained for 62 countries, and six variables with different characteristics (linked to the spread of COVID-19) are identified. In this study, the IFCM clustering algorithm is used to determine the dynamic behavior of COVID-19 based on real-world data for multiple countries and Turkey around the world. Data analysis is performed through MATLAB 2018a and R programs. The clustering results revealed that the distribution of dissemination in Brazil, India, and the United States was nearly identical and distinct from that of the 59 other countries.

I
Background: Intellectual disability is part of the neurodevelopmental disorders, affecting 1-3 % of the population. The etiology is multifactorial, being genetic factors an important aspect in the disturbance of adaptative and intellectual skills, their heterogeneous presentation makes clinical and genetic diagnosis more difficult. With the advent of genomic techniques, it has been possible to detect and correlate possible candidate genes that cause these alterations, however, there are genetic variants that are difficult to interpret.
Methods: Through this review it implemented a phenotype / genotype approach with a bioinformatic study, in order to be able to perform the reclassification of clinical significance of such variants according to the recommendation of the American College of Genetics and Genomics (ACMG) and to determine the true clinical of these genomic variants.  This in order to establish an early and timely diagnosis, an specific and directed treatment, an adequate follow up and prognosis and finally to offer an appropriate genetic counseling to the patient and his family group.
Results: The early identification of genomic variations, through software and databases, allows establishing an opportune diagnosis that leads to early treatment, follow-up, prognosis and genetic counseling.

Authors: Mejia Cardona Andres Felipe , Rivera Martínez Wilfredo Antonio , López Garcés José Gabriel
Published: March 2023

La enfermedad de Fabry es un trastorno hereditario de depósito lisosomal progresivo y multisistémico del catabolismo de los glicoesfingolípidos, ligado al cromosoma X, originando depósito intracelular de glicoesfingolipidos especialmente de globotriaosil-ceramida (Gb-3), principalmente a nivel del endotelio vascular, pero también puede depositarte en otros tejidos. Sus manifestaciones clínicas y de laboratorios son dependientes del órgano comprometido, principalmente el riñón, corazón, sistema nervioso, tracto gastrointestinal y piel, aunque puede involucrar cualquier órgano o sistema. El compromiso renal es el primer signo de daño de órgano blanco en la mayoría de los pacientes con la presentación clásica, manifestándose con proteinuria progresiva, y disminución de la función renal asociada. El diagnóstico Fabry puede retrasarse hasta 10 años o más, desde la aparición clínica de la enfermedad y se realiza con medición de la actividad de la enzima alfa-galactosidasa, principalmente en hombres y requiere estudio genético en mujeres. La biopsia renal es una prueba diagnóstica complementaria, cuando el riñón resulta afectado. La terapia de reemplazo enzimático o el uso de chaperonas constituyen las opciones de manejo farmacológico, se escogen según el perfil del paciente y las mutaciones asociadas.

Published: March 2023

Primary hyperaldosteronism is a condition directly related to arterial hypertension, being the first etiology of secondary origin; given the low suspiciousness the diagnosis is not frequently made, however it has a few steps in the diagnostic protocol that includes measurement of renin aldosterone activity, confirmatory tests such as the saline test and imaging studies such as tomography of the adrenal glands; management can be medical or surgical, impacting on the control of blood pressure and a great number of related pathologies such as atrial fibrillation, obesity and obstructive hypopnea sleep apnea, reducing the high morbidity and mortality of these associated conditions, so it is very important to recognize screening measures and diagnosis of primary hyperaldosteronism.
