El confinamiento social en México secundario a la pandemia de COVID-19 provocó un aumento en la prevalencia de ansiedad en personas mayores, así como de las complicaciones de sus enfermedades preexistentes por falta de atención. En el área de la salud, como en diferentes campos, se recurrió al uso de las tecnologías de la información para continuar con la atención de los pacientes. El objetivo del presente estudio fue determinar la utilidad de la telemedicina para disminuir los niveles de ansiedad en adultos mayores mediante la implementación de un Programa gerontológico. Para ello se realizó un estudio cuasiexperimental con 5 personas mayores de 60 años que asistieron a consulta en una unidad de primer nivel de atención en el periodo comprendido del 25 al 31 de marzo de 2021 (previo al confinamiento en México), que contaban un dispositivo (celular, computadora, o Tablet) e internet. Se les aplicó una escala para detectar su ansiedad; posteriormente, se incluyeron en un programa gerontológico de tres sesiones de 30 minutos en tres semanas, a través de una plataforma gratuita de video llamada (Zoom). En cada sesión se alternaron cinco actividades: autoconciencia emocional, respiración profunda, meditación, relajación muscular progresiva de Jacobson e imaginación guiada. De las 5 personas que iniciaron, sólo 4 cumplieron el programa, en el total de éstas se observó una disminución de los niveles de ansiedad, con lo que se concluye que la telemedicina es útil para aplicar programas gerontológicos dirigidos a disminuir los niveles de ansiedad en personas mayores.

O objetivo deste trabalho foi elaborar biscoitos isentos de glúten com farinha de banana verde (FBV), além de avaliar sua composição química e aceitabilidade. Foram elaboradas três formulações: formulação padrão (FP), formulação experimental 1 (F1) e formulação experimental 2 (F2). Na F1, a farinha de trigo foi substituída por 75% de FBV e 25% de farinha de arroz, enquanto na F2 essa substituição foi total pela FBV. Foram realizadas análises de composição físico-química e sensorial dos biscoitos e os resultados avaliados utilizando o programa estatístico GraphPad Prism6®. A composição centesimal mostrou que os biscoitos apresentaram baixo teor de umidade e cinzas, e considerável teor de carboidratos e lipídeos. Em relação à análise sensorial, participaram do estudo 134 provadores não treinados, sendo a maioria do sexo feminino (78%), com idade média de 18 a 25 anos (80%), universitários (74%), com renda média de 1 a 5 salários mínimos por mês (67%). Todos os participantes relataram o hábito de consumir biscoitos. O índice de aceitabilidade para os diferentes atributos (cor, sabor, aroma e textura) foi acima de 70%, sendo considerado, portanto, satisfatório. Os biscoitos com FBV proporcionaram uma alternativa de produto isento de glúten.

Authors:   Department of Mathematics, Gaziantep University, Gaziantep-Turkey, Sahin Memet
Published: December 2021

In a way, the notion of neutrosophic multigroup is an application of neutrosophic multisets to the theory of group. The concept of neutrosophic multigroup is an algebraic structure of neutrosophic multiset that generalizes both the theories of classical group and neutrosophic group. Neutrosophic multigroup constitutes an application of neutrosophic multiset to the elementary theory of classical group. In this paper, we propose the concept of homomorphism on neutrosophic multigroup. We define homomorphism kerlf, automorphism, homomorphic image and homomorphic preimage of neutrosophic multigroup, respectively. Some homomorphic properties of neutrosophic multigroup are explicated. Some homomorphic properties of neutrosophic multigroup are also discussed. This new concept of homomorphism as a bridge among set theory, fuzzy set theory, neutrosophic multiset theory and group theory and also shows the effect of neutrosophic multisets on a group structure. We finally derive the basic properties of neutrosophic multigroup homomorphism and give its applications to group theory

Published: December 2021

Introduction:

Periprosthetic joint infection (PJI) after total joint arthroplasty is a known risk factor for infection in subsequent joint arthroplasty. The purpose of this study was to determine whether prior nonshoulder PJI contributes to the increased risk of infectious complications, greater healthcare utilization, and increased revision surgery after primary total shoulder arthroplasty (TSA).

Methods:

Patients who underwent primary TSA for osteoarthritis with prior nonshoulder PJI were identified in a national database (PearlDiver Technologies) using Current Procedural Terminology and International Classification of Diseases codes. These patients were propensity matched based on age, sex, Charlson Comorbidity Index, smoking status, and obesity (body mass index >30 kg/m2) to a control cohort of patients who underwent primary TSA for osteoarthritis without any prior PJI. Primary outcomes include 1- and 2-year revision rates. Secondary outcomes include healthcare-specific outcomes of readmission, emergency department visits, length of stay, and mortality. Bivariate analysis was conducted using chi-square tests to compare all outcomes and complications between both cohorts.

Results:

Compared with patients without prior PJI, those with prior PJI had a significantly higher risk of 90-day surgical site infection (7.61% versus 0.56%) and sepsis (1.79% versus 0.56%) after TSA (P < 0.05 for both). Patients with prior PJI also had a higher risk of 90-day readmission compared with those without prior PJI (3.36% versus 1.23%, P = 0.008). In terms of surgical complications, patients with prior PJI had significantly higher risk of 2-year revision surgery compared with patients without prior PJI (3.36% versus 1.57%, P = 0.034).

Conclusion:

Prior nonshoulder PJI of any joint increases rates of 90-day surgical site infection, sepsis, and hospital readmission, as well as 2-year all-cause revision after TSA. These results are important for risk-stratifying patients undergoing TSA with prior history of PJI.

Published: December 2021

Introduction:

Both transforaminal lumbar interbody fusion (TLIF) and lateral lumbar interbody fusion (LLIF) are suitable for achievement of lumbar arthrodesis. Comparative studies have observed complications and outcomes without stratification by lumbar level. This study aims to assess patient-reported outcome measures (PROMs) and recovery in TLIF and LLIF at L4-5.

Methods:

Patients undergoing primary, elective, single-level, TLIF or LLIF procedures at L4-5 were grouped. Demographics, perioperative characteristics, and postoperative complication rates were collected. PROMs included Patient-Reported Outcome Measurement Information System Physical Function, visual analog scale (VAS) back and leg, Oswestry Disability Index, and 12-Item Short-Form Physical Component Summary, and Mental Component Summary and were collected at preoperative, 6-week, 12-week, 6-month, 1-year, and 2-year time points. Delta values and recovery ratios (RRs) were calculated for all PROMs at all time points. Demographics, perioperative characteristics, and postoperative complications were compared using chi-squared and Student t-test for categorical and continuous variables, respectively. Differences in mean PROMs, delta values, and RR at each time point were evaluated using unpaired Student's t-test.

Results:

Three hundred sixty TLIF and 46 LLIF patients were included. Most (54.3%) were men, mean age 56.3 years, and mean body mass index 30.8 kg/m2. Body mass index and insurance significantly differed (P ≤ 0.045, all). TLIF showed significantly greater mean operative time, length of stay, and postoperative narcotic consumption (P < 0.033, all) and greater postoperative nausea/vomiting (P = 0.004). No preoperative PROMs significantly differed. TLIF cohort had significantly greater VAS back at 6 months and VAS leg at 12 weeks and 6 months (P < 0.034, all). No mean delta PROMs or RRs significantly differed.

Discussion:

LLIF demonstrated significantly reduced length of stay, postoperative narcotic consumption, and postoperative nausea/vomiting and significantly improved VAS back at 6 months and VAS leg at 12 weeks and 6 months versus TLIF. Although 2-year PROMs and RRs did not significantly differ, our findings may suggest improved midterm follow-up pain scores for LLIF patients.

Published: December 2021

The results of an experimental study of weakly nonlinear interaction mechanisms of the instability waves in a supersonic boundary layer on flat plate at Mach number М = 2 are presented in the paper. The downstream evolution of artificial disturbances of small amplitude was studied experimentally. The wave characteristics of traveling disturbances were determined. Obtained, that disturbances evolution at basic frequency was happen in according to the linear theory of hydrodynamical stability. Confirmed, that subharmonical resonance on asymmetrical wave triplet was the reason of amplification of the high inclined subharmonic pulsations. The role of high-frequency disturbances was not significant in the region of weakly nonlinear interactions. The initial stage of a parametrical resonance was characterized by appearance of a stationary wave, jumps of a phase on 180° on frequency of a subharmonic in a cross-section direction, and also not symmetry in amplitude β-spectra.

Published: December 2021

In frames of the weakly nonlinear stability theory a disturbances interaction in a hypersonic boundary layer is considered. It is established that nonlinear interaction in a hypersonic boundary layer is probably, it is carried out between waves of the different nature (acoustical and vortical) in a parametric resonance regime. For three-dimensional vortical waves similar interaction is more intensively. The plane acoustical wave which increases more intensively in comparison with the threedimensional is the pumping wave. There are intensity threshold values of the nonlinear interaction beginning and threshold values of the explosive growth beginning. It is possible to expect, that nonlinear interactions for vortical waves which are carried out in wide frequency band can lead to a package growth of Tollmien-Schlichting waves.

Phenomena in space charge dominated beams are described by the locally cold beam model precisely enough. The model is applied to the effects of longitudinal and transverse inhomogeneities of space charge. It was validated that the phenomenon of emittance oscillation in these beams, which is used in well known technique emittance compensation, is the property of the model and does not depend explicitly on the properties of a beamline. A universal formula for emittance estimation of locally cold beams in beamlines is presented.

The physical parameters of various electronics devices are depended on the properties of semiconductor interface, in particular, surface morphology. The aim of our research was to investigate a influence of chemical treatment and a vacuum annealing of substrates with and without indium flux on the morphology of InAs (111)A surface. The growth of InAs layers by molecular-beam epitaxy was conducted after oxide layer desorption. The morphology of the surface was inspected by the atomic force microscopy method at each stage. It was shown that only the treatment of InAs (111)A surface by HCl in isopropyl alcohol solution allows to obtain smoother surface after thermal annealing in compare with other etches. The using of indium flux during the oxide deleting increases this effect. The oxide thermal desorption modes from InAs (111)A surface in vacuum and in indium flux are defined. The character of surface roughness change with increase of epitaxy layer thickness is determined.

Published: December 2021

Experiments on the attenuated total reflection spectroscopy in the terahertz region were carried out using two homemade modules with silicon prisms developed for Fourier spectrometers and a free electron laser as radiation source. Spectra of water, water solutions, perfluorodecaline, paraffine oil, and amino acid powders were recorded. Real and imaging parts of the refractive index were retrieved using Kronig-Kramers transform or by direct solution of Fresnel equations. For a monochromatic radiation source two measurements at two different incident angles, rather than for two polarizations, were found to be an optimal method for the complex refractive index determination.

Interest to semiconductor nanocrystals in dielectric matrix is raised by observation of quantum-size effects in such structures even at room temperature. The approach for crystallization of clusters of amorphous silicon in SiNx (0.6 < x < 1.3) films deposited on glass substrates was supposed and developed. The approach is based on nanosecond pulse treatments by excimer KrF laser irradiation. Relatively big energy of photon (5 eV) leads to effective absorbance of the laser irradiation in the SiNx films, causing pulse heating and consequent crystallization of amorphous silicon clusters. The analysis of phase composition of the clusters has been carried out using Raman scattering spectroscopy.

Published: December 2021

In this manuscript we propose two methods to solve inverse light scattering problem for single particles, which can be described as a coated sphere. The efficiency of the methods is illustrated by characterization of lymphocytes and stem cells using light scattering patterns obtained with scanning flow cytometer. Both methods, spectral and global optimization, were used to obtain diameters and refractive indices of the cytoplasm and the nucleus of mice embryo stem cells and human lymphocytes. These results agree with data obtained from other studies. Determination of these parameters is important for diagnostics of pathological states of lymphocytes and differentiation status of embryo stem cells. Moreover, methods described in this manuscript are applicable to all mononuclear cells. We also considered limitations of these methods and their possible improvements.

In the work, a method of application of scanning flow cytometry for investigation of the aggregation dynamics of invitro activated thrombocytes is presented. As a result, the rate constant of creation of initial aggregates, – dimers, – from single thrombocytes, and the effective steric factor of aggregation, which characterized the thrombocytes activation degree, are determined. The study reveals diagnostic potential of the scanning flow cytometer in determination of relative concentrations of aggregates and non-aggregated thrombocytes in a sample by measuring light-scattering signals from single particles and evolution of the distribution function of the particles on the signals. Theoretical treatment of the experimental data is based on modeling the particles aggregation kinetics with the use of Smoluchovski equation.

Introduction: It is known that very few issues related to death and religiosity/spirituality are addressed during medical graduation. Understanding the process of death and dying is still a problem for medical students before the terminal condition of a patient. Probably the medical students of the fifth graders overestimate their abilities, probably because they have not yet had contact with terminally ill patients or because they have not graduated, they do not take responsibility for the death of a patient they are following. In Brazil, many students believe that the topic of spirituality influences health, but they do not feel prepared to address this issue with patients. Objective: It was to analyze whether there is a relationship between religiosity and thanatophobia in medical students. It also analyzed whether there was a correlation between fear of death and specific religions, sex and age, and the index of religiosity with sex and age. Methods: Followed a prospective observational cross-sectional model, following the STROBE clinical research rules. This study was analyzed and approved by the Research Ethics Committee (CEP) according to a substantiated opinion number 2,031,705, and obtaining the patient's consent. Results: A total of 542 students (61.2% of the total) answered the questionnaire. Most were female (65.7%) and with a mean age of 22.31 (ranging from 17 to 39 years). The majority of students have a religion (90.1%) and 90.4% considered it important to address the issue of death and religiousness during graduation. In this study, it was observed that most students, in addition to having some kind of religion, consider it important to address the themes highlighted during the course. This was similar to the findings in other studies. There was no statistically significant relationship between having a religion and being less afraid of death. However, students with higher levels of intrinsic religiosity showed greater discomfort when dealing with terminal patients. Furthermore, no studies comparing these two subjects were found. It was also found in this research that students with high levels of religiosity consider it more important to address the issues in question, with the majority being female students. Conclusion: It is necessary to include the topic in the medical academy, and it is essential to prepare a more humanistic and dedicated professional for patients, whether active or palliative treatment.

Autistic Spectrum Disorder (ASD) is a syndrome which affects 70 million people worldwide, 2 million of them only in Brazil, according to the World Health Organization. Given this, the bond between children with ASD in their socio-school environment is still complicated due to the lack of understanding of the subject by the individuals around them. Due to the population's lack of awareness on the subject, the perpetuation of stereotypes is remarkable and corroborates the presence of stigmas and prejudgments, jeopardizing even further the individual's socialization. The present report aimed to show the experience of medical students interviewing the mother of an autistic individual, and how this activity helped to understand the syndrome and how to deal with a patient with ASD. Therefore, the experience of interviewing the mother of an autistic person, through an online platform, brought questions to the personal and professional development of the students, as they were faced with a completely different reality. At the end of the interview, the prejudices, the difficulties of inclusion and accessibility that individuals with autism spectrum experience were highlighted, being essential a greater dedication and responsibility to improve their quality of life. In addition, it highlights the importance of this experience for the construction of the doctor-patient relationship among the students, as it promotes a more humanized Medicine, by making them see different points of view.

Bu çalışmada, web uygulama saldırılarının hibrit saldırı tespit sistemleri ile daha kolay ve daha doğru tespiti için sezgisel öznitelik seçimi ve makine öğrenmesine dayanan bir yaklaşım önerilmektedir. CIC-IDS2017 ve CSE-CIC-IDS2018 veri setlerindeki web uygulama saldırıları ve normal akış örnekleri bir dizi veri ön işleme aşaması sonrası birleştirilerek ve yeni bir veri seti oluşturuldu. Genetik Algoritma ve Lojistik Regresyon kullanılarak ortalama karesel hata ve öznitelik sayısı optimizasyonu gerçekleştirilip sonuçlar beş farklı makine öğrenmesi algoritması ile test edildi. Elde edilen sonuçlar incelendiğinde, öznitelik sayısının %85 oranında azaltılmasına rağmen sınıflandırmadaki başarım oranlarının %99 seviyesinde kaldığı gözlemlenmiştir.

Müşterilere yapılan anlık kur teklifleri, bankacılık sektöründeki en kritik konular arasında yer almaktadır. Verilen tekliflerin uygun seviyede olması hem banka hem de müşteri açısından oldukça önemlidir. Bu çalışmada, müşteriye verilen kur tekliflerinin tahmini için yaklaşık 8 aylık veri kullanılmış ve tahmin modelleri tasarlanmıştır. Toplamda 18 farklı kur üzerinden çalışma yürütülmüştür. Çalışmada bağımlı değişkenler müşteri segmenti, anlık kur değeri, gün bilgisi, saat bilgisi ve volatilite değeri olarak belirlenmiştir. Bağımsız değişken ise kur marjıdır. Eğitimler günlük verilerle ve Rastgele Ağaçlar (RF), Gradyan Arttırma Makinesi (GBM), Yapay Sinir Ağları (ANN), Derin Sinir Ağları (DNN), Evrişimli Sinir Ağları (CNN) ve Elman Sinir Ağı algoritmaları kullanılarak gerçekleştirilmiştir. Algoritmaların hiper-parametrelerini bulmak için rastgele arama algoritması kullanılmış ve model eğitimlerinin sonuçları karşılaştırılarak en düşük hata değerine sahip modeller tahmin aşamasında kullanılmak üzere seçilmiştir. Başarım ölçümü için Ortalama Kare Hata (MSE) ve Ortalama Mutlak Hata (MAE) hata fonksiyonları kullanılmıştır. Üç farklı model üzerinden gerçekleştirilen eğitimlere göre yapay sinir ağları ve evrişimli sinir ağları algoritmalarının diğer algoritmalara göre daha iyi sonuçlar verdiği gözlemlenmiştir. 18 kur için tahmin süresi yaklaşık 3s'dir.

Eleme turnuvaları, yarışma tasarımlarının muhtemelen en yaygın olarak kullanılanıdır. Bu turnuvalarda, her turda tüm yarışmacılar bir eleme karşılaşması oynamak üzere eşlenirler ve kaybeden turnuva dışında kalır. Seribaşı eşlemesi olarak adlandırılan ilk tur maçlarının seçimi, turnuvanın geri kalanını da doğrudan etkiler. Seribaşı eşlemelerini çeşitli açılardan değerlendiren ve inceleyen, dikkate değer sayıda çalışma olmasına karşın, bildiğimiz kadarıyla seribaşı eşlemelerini sayımlayan bir algoritma sunulmamıştır. Ayrıca, literatürde farklı seribaşı eşlemelerinin sayısının bulunması da yalnızca kısaca tartışılmıştır. Bu makalede farklı seribaşı eşlemelerinin nasıl sayılacağı tartışılmış ve eleme turnuvalarında seribaşı eşlemelerinin sayımlanması için etkin bir algoritma önerilmiştir.

Hızla ve kontrolsüzce artan veri dünyasında, veri tekilleştirme büyük bir ihtiyaçtır. Veri tekilleştirme, veri tabanında yinelenen verilerin kopyalarını ortadan kaldırmak ya da onları tespit ederek, eşsiz kimlik numarası ile betimlemek için kullanılan bir tekniktir. Oteller veri tabanında; ismi, adresi, acente bilgisi, ve fiyat bilgisi bulunan bir otelin, kayıtlarda farklı isim ve kimlik numaları ile bulunması, karşılaştırma olanağı sunmamaktadır. Rakip analizinin tam anlamıyla yapılabilmesi, rakip fiyat durumlarının bilinmesi ve pazar takibi bütün bu otel isimlerinin tekilleştirilmesi ile mümkündür. Bu çalışmanın amacı, otel isimlerini eşleştirerek, eş olan otelleri tek bir kimlik numarası ile tanımlamak ve tekil veriyi elde etmektir.
Veri tekilleştirme için çeşitli metin benzerliği algoritmaları kullanılır. Bu çalışmada, Metin Benzerliği algoritmaları otel isimleri üzerinden karşılaştırılmıştır. Mesafe düzenleme bazlı benzerlik, belirteç bazlı benzerlik, diziliş tabanlı benzerlik algoritmaları ile bulanık dize eşleme algoritmaları incelenmiştir. Çalışmanın sonucunda Bulanık dize eşleme algoritmasının ve Jaro Winkler mesafesinin birlikte kullanıldığı hibrit bir model önerilmiştir.

Bu çalışmada 27 Mayıs 1960 askerî müdahalesi sonrasında Orgeneral Cemal Gürsel başkanlığında yönetimi devralan Millî Birlik Komitesi’nin (MBK) üyesi olarak darbeden sonra fiilî anlamda başbakanlık görevini üstlenen ancak 13 Kasım 1960’ta tasfiye edilerek kendisine askerî vesayet yönetimince Hindistan’da müşavirlik görevi ihdas edilen Alparslan Türkeş’in Yeni Delhi’deki siyasi faaliyetleri incelenmektedir. Bu araştırmada 13 Kasım 1960 tasfiyesi ve Türkeş’in sürgüne gönderilişine, sürgündeki faaliyetlerine, yurda dönüşüne ayrıca onun siyasete giriş sürecine kısaca değinilmektedir. Türkeş yurt dışı görevini ifa ederken bir taraftan da önemli siyasi faaliyetlerde bulunmuştur. Onun sürgündeki siyasi faaliyetlerden ilki kendisiyle birlikte tasfiye edilen 14’lerin diğer mensuplarına ulaşması ve yazdığı mektuplar vasıtasıyla son ana kadar grubun motivasyonunu yüksek tutmasıdır. İkinci olarak Türkeş, ülke açısından hayati öneme sahip meselelerde yurt dışında bulunmasına rağmen dönemin idarecilerine ikazda bulunmayı kendisine bir görev addetmiştir. Türkeş, kendisi zor şartlar altında iken Adnan Menderes ve arkadaşlarının idam edilmemesi için büyük çaba sarf etmiştir. Türkeş’in ana faaliyetlerinden üçüncüsü ise sürgündeyken aktif siyasete katılmak niyetinde olmadığını beyan etmiş olmasına rağmen karizmatik bir lider adayı olarak kamuoyu oluşturabilmesidir. Ana gayesini özetlediğimiz bu çalışmada kitaplar yanında süreli yayınlar ve Türkeş’in bizzat kaleme aldığı mektupları kapsamlı olarak incelenmiştir.

Fishing in Salty Waters: Poverty, Occupational Saline Exposure, and Women’s Health in the Indian Sundarban
Authors: Dasgupta Susmita , Wheeler David , Ghosh Santadas
Published: December 2021

Collecting wild tiger prawn seedlings, also known as prawn post-larvae (PL), from rivers and creeks is an important occupation for more than 100,000 poor women in India’s Sundarban estuarine delta. Prawn PL collecting requires many hours of immersion in saline river water. This paper uses a large household survey to explore the determinants of poor women’s engagement in this occupation and the health impacts. The results reveal high significance for two variables: (i) the opportunity wage, proxied by years of education and (ii) child-care demands, proxied by the household child-dependency ratio. Together, these variables are sufficient to distinguish between women who have no engagement with prawn PL collecting and those with many years of engagement. The probability of self-reported health problems is also significantly higher for women with more saline exposure from prawn PL collecting and whose drinking water is from tube wells with higher salinity.

Land degradation and desertification (LDD) and climate change are having increased effects in the Near East and North Africa (NENA) impacting the livelihoods of about 410 million people. Agriculture is a vital sector, contributing on average 14% to the Gross Domestic Product (GDP) (excluding oil producing countries) and providing jobs and incomes for 38% of the region’s economically active population. Nevertheless, most NENA countries import at least 50% of the calories they consume. Furthermore, it is estimated that the total area that is desertified or is vulnerable to desertification cover 9.84 million km2 or about 86.7% of the total NENA region. Soil erosion by water, wind, and sand and dust storms (SDS) cause losses of about USD 13 billion of GDP each year. To confront these hardships, the region must endorse proper land use planning, prioritization of target areas for restoration and adoption of sustainable land and water management (SLWM) to reverse the situation. This paper analyses the inter-linkages between LDD, resource base management and food security under different scenarios and offers mitigation and remediation options. These include knowledge management and sharing; establishment of a regional platform to facilitate dialogue; public and private investment opportunities; provision of tools to scale-out sustainable land and water management options; and creation of a conducive enabling environment supported by policies and strategies. The paper provides policy and decision-makers with priority actions and options to enhance productivity, and combat land degradation to improve food security in the region.
