Student Support for Online Learning at the University of KwaZulu-Natal: A Psychological Readiness and Student Satisfaction Perspective
Authors: Subban Mogie , Padayachee Indira , Soni Sanjay
Published: January 2023

Remote working and online learning are rapidly becoming the norm in higher education and other sectors of society. Student engagement in online learning requires enthusiasm and effort from learners, as well as a necessary supportive environment to improve learning outcomes. Understanding students’ preparedness to undertake online learning is crucial to the successful usage of online learning in the post-Covid-19 era. This article discusses empirical results of psychological readiness, amongst others, of students to use online learning in a university environment for success. The study that directed this article was conducted amongst 400 undergraduate students in the School of Management, Information Technology and Governance (SMIG) at the University of KwaZulu-Natal (UKZN), employing a descriptive research design and convenience-based purposeful sampling. Analysis of data revealed evidential areas relating to psychological readiness for online learning that may require support interventions to address certain issues. These include distraction from other online activities when learning online, not having a preference for online learning, difficulty in coping with online learning, and respondents being fearful or anxious when learning online. In addition, support may need to be provided to improve overall student satisfaction with online learning and related aspects. Correlational analysis revealed that overall student satisfaction with online learning would increase if students could cope better with online learning, engage effectively with online learning materials, and work at their own pace. Given online learning expansion in higher education, the findings of the study underscore the utility of adequate student preparedness and sustained student support for the prevalence and significance of flexible learning in a dynamic post-Covid-19 environment.

Published: January 2023

The outbreak of the novel Coronavirus disease (COVID-19), which was declared a global pandemic on 11 March 2020, has upended the world. To combat its spread, social distancing was adopted as recommended by health professionals and the higher education institutions (HEIs) were not spared. Despite the continuation of the academic agenda, social distancing forced lecturers and their students apart. As a result, the goal of this study was to examine factors that influence pre-service teachers’ acceptance of online learning to promote social distancing. The study used a quantitative design, with data gathered from 163 pre-service teachers. It was underpinned by the Technology Acceptance Model (TAM). Partial Least Squares–Structural Equation Modelling (PLS–SEM) was used to test the hypothesised model using SmartPLS version 3.2.8 in the analysis. The model identified six factors that predict pre-service teachers’ acceptance of online learning, with a variance of 66.8% in behavioural intention to use online learning. This means that the six factors were good predictors of pre-service teachers’ acceptance of online learning to promote social distancing. Pre-service teachers’ perceived attitude towards the use of online learning plays a key role in their acceptance of online learning given its explained variance of 54.7%. As a result, in order for online learning to properly promote social distancing, the Department of Higher Education and Training (DHET) should focus more on the factors that improve pre-service teachers’ attitude towards using it.

Background. Basal cell skin cancer is the most common malignant epithelial skin neoplasm in fair-skinned people and accounts for two-thirds of all skin cancers in this population. Tumor lesions have a supporting vascular network that serves as a target for vascular selective lasers.
Aims. To assess the effects of laser radiation at a wavelength of 585 and 1064 nm on the vasculature of various forms of basal cell skin cancer using dermatoscopy and in vivo confocal microscopy.
Materials and methods. The study included 20 patients with 20 lesions of histologically confirmed basal cell skin cancer treated with a pulsed dye laser (wavelength 585 nm) and a long-pulse neodymium laser (wavelength 1064 nm) in the conditions of the consultative and diagnostic center of the Federal State Budgetary Institution GNTSDK of the Ministry of Health RF in the period from 2021 to 2022. The effectiveness of therapy was assessed using non-invasive methods for examining the skin.
Results. According to the results of the two-year follow-up period, 100% effectiveness of therapy in both groups is noted, in 2 patients treated with a neodymium laser, the formation of hypertrophic scars in the treatment area is noted.
Conclusions. Treatment of patients with basal cell skin cancer with selective vascular lasers may be an effective treatment option. Additional studies with a larger sample of observations and a long monitoring period are needed to confirm the effectiveness of this treatment method.

Published: January 2023

Ülkeler açısından ekonomik entegrasyonlar, pazar ve piyasa bütünleşmesine, milli gelirin artışına, ekonomik kutuplaşmalardan korunmasına ve teknolojik yayılıma imkân sağlamasından dolayı büyük önem taşımaktadır. Ülkeler açısından önemli bir diğer konu ise teknolojik dönüşümü sağlayarak teknoloji kapasitelerini yükseltmektir. Teknolojik kapasiteyi arttırmanın literatürde iki alternatifi bulunmaktadır. Birinci alternatif Ar-Ge faaliyetlerine yoğunlaşarak kendi teknoloji üretimini sağlamak, ikincisi ve en çok tercih edilen yöntem olarak teknolojiyi transfer etmektir. Bu nedenle günümüz uluslararası rekabet ortamında ülkeler açısından önemli olan ekonomik entegrasyon ve teknolojik dönüşüm arasındaki karşılıklı ilişkiden, ekonomik entegrasyonların teknoloji transferine olan etkisinin tespit edilmesi araştırma konusu olarak değerlendirilmiştir. Araştırma konusu çerçevesinde Türkiye’nin entegrasyonlar yoluyla yapmış olduğu teknoloji transferine ve ülke içindeki yüksek teknoloji üretimine, AB ve ASEAN entegrasyonlarının etkilerinin incelenmesi çalışmamızın amacını oluşturmaktadır. Çalışmanın analiz kısmında 1996-2021 yıllarını kapsayan Türkiye, Avrupa Birliği (AB) ve ASEAN’a ait veriler kullanılmıştır. Çalışmanın amacına uygun yöntem olarak Peseran, Shin ve Smith (2001) ARDL sınır testi yaklaşımı belirlenmiştir. Analiz sonucunda Avrupa Birliği (AB) ve ASEAN açısından kısa ve uzun dönemde anlamlı ve pozitif sonuçların elde edilmiş ve ekonomik entegrasyonlar arasında AB’nin Türkiye’deki teknoloji kapasitesinin arttırılması noktasında katkısının daha fazla olduğu tespit edilmiştir. Ayrıca analizden çıkan bir başka sonuç da her iki entegrasyondan sağlanan doğrudan yabancı yatırımlarının (DYY) ve yüksek teknoloji ithalatının Türkiye’nin teknoloji seviyesine katkı yaptığı tespit edilmiştir.
Orijinal, Radikal ve Yönetimsel: Thorstein Veblen ve Amerikan Kurumsalcılığının Toplumsal Sınıf Kökenleri
Authors: ŞENALP Mehmet Gürsan
Published: January 2023

Bu çalışma, ABD'de Yaldızlı Çağ (Gilded Age) olarak bilinen 1800'lerin son çeyreği ile 20. yüzyılın ilk yarısına – İlerici Dönem (Progressive Era) ve Yeni Düzen (New Deal) yıllarına – odaklanmaktadır. Bunu yaparken, makale ilk başta Amerikan kurumsalcılarının bazı önde gelen isimlerinin yoğun şekilde etkilendikleri Alman Tarihsel Okulu ve Amerikan Siyasal İktisat Okulu (ya da Amerikan Okulu) ile ilişkilerine bakıyor. Yaygın görüş kurumsalcılığın neoklasik iktisadın hegemonyasına direnebilmiş ve Amerikan üniversitelerindeki iktisat bölümlerinde önemli bir ağırlık elde edebilmiş olduğu yönündedir. Dolayısıyla, çalışmanın ilk iki bölümü kurumsalcılığın, ‘Amerikan’, ‘orijinal’ ve ‘radikal’ olarak anılan unsurlarına odaklanıyor. Yazının asli meselesi ise şu: “Veblen gibi bir figürün Amerikan kapitalizmine karşı radikal görüşleri ve sonradan görme zenginlerin gösterişçi yaşam tarzlarıyla alay eden iğneleyici yazılarıyla özdeş Kurumsalcı/Evrimselci iktisat, ABD akademisi, araştırma enstitüleri ve bürokrasisinde ‘neoklasik teoriyle eşit önemde’ görülüp bir tür ana akım konumunu nasıl edebildi?” Bu bağlamda, çalışma, Amerikan Kurumsalcılığının şekillendiği ve etkili olduğu üç farklı kesite odaklanıyor. Bunların ilk ikisinde (1) Alman Tarihsel Okulu'nun Almanya’da tahsil görmüş ‘yeni nesil’ iktisatçılar aracılığıyla yarattığı etki, (2) 20. yüzyılın ortalarında artık çoktan unutulmuş Amerikan Okulu’nun korumacı/milliyetçi doktrinlerinin etkisi üzerine odaklanılıyor. Yazı, son olarak (3) Amerikan kurumsalcılığının toplumsal sınıf kökenlerini açığa çıkaran 1930’lardaki ‘yönetimsel devrim’ tartışmalarına uzanıyor. Burada Amerikan kurumsalcılarının, Yeni Düzen yıllarında yükselen ‘yönetimsel sınıfın’ ilerici unsurlarını temsil eden ‘organik aydınları’ olduğu ve geleneğin ABD'deki başarısının arkasında bu organik ilişkinin bulunduğu iddia ediliyor.

Kadına Yönelik Şiddetle Mücadelede Kullanılan Mobil Uygulamaların Kamu Değeri Perspektifinden Değerlendirilmesi
Authors: DEMİR Tülay , NALBANT Fatma
Published: January 2023

Dijital çağ olarak adlandırılan bu dönemde e-devlet uygulamaları içerisinde mobil teknolojiler kamu hizmetlerinin sunumunda önemli bir araç haline gelmiştir. Mobil uygulamaların, dijitalleşme sürecinin olağan bir sonucu olarak küresel ve toplumsal bir sorun olan kadına yönelik şiddetin önlenmesini amaçlayan kamu politikaları arasında da ön plana çıktığı görülmektedir. Bu uygulamalar, kadına yönelik şiddet riskinin ve tehdit oluşturabilecek durumların önüne geçilmesinde olumlu sonuçlar doğurmaktadır. Ayrıca kamu hizmetinin önemli bir parçası olan bu uygulamalar her alanda, yalnızca hizmetten yararlananlar için değil tüm toplum için değer yaratmaktadır. Devletin; hizmetleri, yasal düzenlemeleri ve diğer eylemleri aracılığıyla yarattığı bu değer ise literatürde kamu değeri olarak tanımlanmaktadır. Bu kapsamda çalışmada kadına yönelik şiddetle mücadelede kamu politikası aracı olarak gerçekleştirilen mobil uygulamaların, kamu değeri ortaya koyma başarısının değerlendirilmesi amaçlanmaktadır. Bu amaç doğrultusunda kamu politikası aktörlerinden İçişleri Bakanlığı ile Aile ve Sosyal Politikalar Bakanlığı bünyesinde kadına yönelik şiddetle mücadelede geliştirilen Kadın Destek Uygulaması (KADES) ve ALO 183 Sosyal Destek Hattı projeleri, kamu değeri perspektifinden ele alınmıştır. Bu uygulamaların literatürde kamu değerinin ölçülmesinde kullanılan “sonuç başarısı”, “güven ve meşruiyet”, “hizmet sunumu kalitesi” ve “etkinlik-verimlilik” ölçütleri bakımından doküman analizi yöntemiyle değerlendirilmesi sonucunda ilgili politikaların kamu değeri yaratma başarısını kısıtlayan nedenler olduğu tespit edilmiştir. Çalışma, politika uygulayıcılarının kadına yönelik şiddetle mücadele politikalarında değer odaklı bakış açısıyla hareket etmelerine yönelik tavsiyelere yer verilerek sonlandırılmıştır.
Quo Vadis Neoliberalism: A Carefrontation of Veblen, Keynes, and Marx
Authors: KAHYA AYDIN Pınar
Published: January 2023

Neoliberalism is still main reference point of economic thought in economics departments of universities and hegemonic ideology of policy makers although it comes in harsh criticisms for policy outcomes particularly deepening global inequality from wide range of scholars, journalists and even some policy networks especially after 2008-9 financial crisis. These criticisms are meaningful in terms of questioning neoliberal hegemony even so the motto of neoliberalism which is “there is no alternative” has not been responded as “nope, there is an alternative” yet at least as a counter hegemonic position for global political and economic system. The article sets out to formulate the need of going beyond criticisms and creating a reference toolbox kit to face with neoliberal hegemony. Is it possible to create an alternative method of thought in economics via eliminating deficiencies of particular schools of thought? In particular, is it possible to create a holistic response from different schools of non-mainstream economics focusing on neoliberalism as a concrete case for objection? The answer is yes. In this study, three different schools of economic thought, evolutionary institutionalism, Keynesianism and Marxism are mutually considered and the theoretical possibility of a holistic opposition in different levels is affirmed in a way of their stances in against neoliberalism.

Purpura fulminans (PF), a life-threatening disorder characterized by cutaneous microvascular thrombosis with secondary hemorrhagic infarction, is a rare complication of sepsis and may also be caused by severe protein C or protein S deficiency. Here, we describe the case of a 58-year-old man who developed PF in close association with the onset of chronic lymphocytic leukemia (CLL). PF initially manifested with an ecchymosis of the right upper leg in the absence of sepsis or disseminated intravascular coagulation. PF was likely triggered by antiendothelial IgG autoantibodies functionally interfering with the anticoagulant protein C-protein S-thrombomodulin system on EA.hy926 endothelial cells in a modified thrombin generation assay. Although plasma exchange and immunosuppressive therapy with cyclophosphamide were temporarily effective, PF eventually progressed and the patient died from septic shock during treatment-associated neutropenia. In rare occasions, CLL may be associated with autoimmune-mediated PF requiring prompt diagnosis and aggressive multimodal therapy.

Background: Corona Virus infection is rapidly expanding and has a significant worldwide influence on the status of health and the economic process. Aim: Performing a literature search to investigate possible impacts of transmission of COVID-19 disease through blood transfusion process in health care system, and disease prevalence. Methods: Internet search in scientific publications and collecting data regarding different viral transmission routes, viral detection and disease diagnosis methods, what are the potential problems and risks in COVID-19 management, and COVID-19 protective measures to undertake during blood transfusion. Discussion and Conclusion: Coronavirus spreads mostly by droplets produced by infected persons while coughing, sneezing, or speaking. Different Covid-19 diagnosis methods include Computed Tomography (CT) scan, reverse transcription-polymerase chain reaction, antibody testing (IgG, and IgM), and biochemical tests. Different disease management risks may occur including antibiotic resistance, occupational stress, immune function suppression or dysregulation, pharmacodynamic interactions like prolongation of the QT interval. Although the findings indicated that blood transfusion did not transmitted coronavirus, but protective measures should be undertaken during blood transfusion process in healthcare facilities and blood transfusion centers. This will aid in mitigating viral transmission and associated management risks that may occur.

Sardinia, an Italian island in the Mediterranean sea with a population of 1,7 millions, has one of the highest incidence of β-thalassemia with 10-12% of carriers. Since 1977 we have been offering a capillary screening program and prenatal diagnosis to couples following non-directive genetic counselling. Thanks to the implementation of new molecular analysis methods, we shifted from prenatal diagnosis performed in 2nd trimester of pregnancy to 1st trimester. In order to avoid termination of pregnancy in case of affected fetuses following prenatal diagnosis we introduced preimplantation genetic testing, thus increasing notably the acceptance rate of antenatal screening and diagnosis by couples at high risk. In this paper, we report the continuous experience of our prenatal centre in Sardinia in 9,324 antenatal diagnoses of β-thalassemia, the accuracy and safety related to the prenatal procedures we employed, the termination of pregnancy rate and the couples’ acceptance of the different approaches as well as analyze the screening programs available to the Sardinian population. Molecular screening by Polymerase Chain Reaction (PCR) based methods, prenatal diagnosis by Chorionic Villous Sampling (CVS) with very low fetal loss rate (0,3%) and Preimplantation Genetic Diagnosis (PGD) were the most common techniques applied in our prenatal centre and they have brought to a drastical reduction of newborns affected by β-thalassemia to only 3-5 per year.
Red Blood Cells as Drug Delivery and Imaging Agents: An Update
Authors:   Department of Diagnostic Imaging and Interventional Radiology, H. Lee Moffitt Cancer Center & Research Institute, USA, JW Choi
Published: January 2023

Red blood cells are essential physiologic cellular components that are produced constantly at abundant levels throughout life, making them an easily obtainable vehicle for both targeted cellular delivery of exogenous drugs as well as non-invasive in vivo imaging of the vasculature. As red blood cells are readily acquired in sufficient quantities and minimally immunogenic by nature, red blood cell-based agents may allow delivery of pharmaceuticals into the body under conditions of both reduced toxicity and increased physiologic half-life, when compared to the non-carrier-based drug equivalent. Research efforts in this area have recently seen major advances that are likely to accelerate the translation of red blood cell-based carrier methods into the clinical setting in the near future. This includes the coupling of therapeutic agents to the external surface of red blood cells, as well as more refined methods for internal encapsulation of drugs within red blood cells or cell-based derivatives. Here we review some of the more recent advances in the field regarding the loading of various therapeutic agents onto red blood cells as well as the use of red blood cell based imaging agents for in vivo vascularity imaging.
Direct π-Activation vs. O-Activation in Halogen Bonding Catalysis
Authors: Robidas Raphaël , Legault Claude
Published: January 2023

Halogen bond donors had an increasing impact on catalysis in recent years, and their development is highly active. In particular, numerous iodine-based halogen bond donors have been developed and used to promote various reactions through coordinating carbonyl groups, a ubiquitous mode of activation in catalysis. We now report computational data which strongly suggests that an alternative activation mode, through direct π-complexation, is operative for unsaturated carbonyl substrates. Calculations also suggest that solvent polarity could have a clear impact on the preference of the mode of activation, raising the possibility of a mechanistic manifold switch through solvent variation. These findings could profoundly impact the development of the next generation of such halogen-bond donor catalysts.
Copper-Catalyzed, Aerobic Aminooxygenation of N-Alkoxycinnamyl Carbamates via Substrate-Promoted Catalyst Activation
Authors: McNichol Caitlyn P. , DeCicco Ethan M. , Canfield Amanda M. , Carstairs Daniel P. , Paradine Shauna M.
Published: January 2023

We report a method for a ligand-enabled, copper-catalyzed, aerobic aminooxygenation of internal alkenes. The synergistic combination of a phenanthroline-based ligand and substrate coordination promotes reduction of Cu(II) to Cu(I), resulting in a cyclization that proceeds via an amidyl radical pathway rather than a previously-established aminocupration path-way. The complementary reactivity enabled by this switch in reaction mechanism provides access to new substrate classes and a considerably broadened scope for this transformation. Experimental evidence supports a free radical mechanism involving substrate-promoted reduction to Cu(I) as well as the role of O2 as both oxidant and functionalizing agent.
Gaussian Approximation Potentials for Accurate Thermal Properties of Two-Dimensional Materials
Authors: Kocabaş Tuğbey , Keceli Murat , Vázquez-Mayagoitia Álvaro , Sevik Cem
Published: January 2023

Two-dimensional materials (2DMs) continue to attract a lot of attention, particularly for their extreme flexibility and superior thermal properties. Molecular dynamics simulations are among the most powerful methods for computing these properties, but their reliability depends on the accuracy of interatomic interactions. While first principles approaches provide the most accurate description of interatomic forces, they are computationally expensive. In contrast, classical force fields are computationally efficient, but have limited accuracy in interatomic force description. Machine learning interatomic potentials, such as Gaussian Approximation Potentials, trained on density functional theory (DFT) calculations offer a compromise by providing both accurate estimation and computational efficiency. In this work, we present a systematic procedure to develop Gaussian approximation potentials for selected 2DMs, graphene, buckled silicene, and h-XN (X = B, Al, and Ga, as binary compounds) structures. We validate our approach through calculations that require various levels of accuracy in interatomic interactions. The calculated phonon dispersion curves and lattice thermal conductivity, obtained through harmonic and anharmonic force constants (including fourth order) are in excellent agreement with DFT results. HIPHIVE calculations, in which the generated GAP potentials were used to compute higher-order force constants instead of DFT, demonstrated the first-principles level accuracy of the potentials for interatomic force description. Molecular dynamics simulations based on phonon density of states calculations, which agree closely with DFT-based calculations, also show the success of the generated potentials in high-temperature simulations.
Local N-electron valence state perturbation theory using pair-natural orbitals based on localized virtual molecular orbitals
Authors: Uemura Kazuma , Saitow Masaaki , Ishimaru Takaki , Yanai Takeshi
Published: January 2023

Second-order N-electron valence state perturbation theory (NEVPT2) is an exactly size- consistent and intruder-state-free multi-reference theory. To accelerate the NEVPT2 computation, Guo and Neese combined it with the local pair-natural orbital (PNO) method using the projected atomic orbitals (PAOs) as the underlying local basis [Guo et al., J. Chem. Phys. 144, 094111 (2016)]. In the present paper, we report the further development of the PNO-NEVPT2 method using the orthonormal and non-redundant localized virtual molecular orbitals (LVMOs) instead of PAOs. The LVMOs were previously considered to perform somewhat poorly compared to PAOs because the resulting orbital domains were unacceptably large in size. Our prior work, however, showed that this drawback can be remedied by re-forming the domain construction scheme using differential overlap integrals (DOIs) [Saitow et al., J. Chem. Phys. 157, 084101 (2022)]. In this work, we develop further refinements to enhance the feasibility of using LVMOs. We first developed a two-level semi-local approach for screening out so-called weak-pairs in order to select or truncate the pairs for PNO constructions more flexibly. As a refinement specific to the Pipek–Mezey localization for LVMOs, we introduced an iterative scheme to truncate the Givens rotations using varying thresholds. We assessed the LVMO-based PNO-NEVPT2 method through benchmark calculations for linear phenylalkanes, which demonstrate that it performs comparably well relative to the PAO-based approach. In addition, we evaluated the Co-C bond dissociation energies for the cobalamin derivatives composed of 200 or more atoms, which confirms that the LVMO-based method can recover more than 99.85% of the canonical NEVPT2 correlation energy.

Este artículo detalla las regulaciones en la calidad del agua en piscinas y agua potable en Alemania, Canadá y Colombia, con una comparación con la regulación existente y los estándares de calidad de las aguas termales. Canadá, Alemania y Colombia regulan que el agua potable debe estar libre de niveles inseguros de sustancias y patógenos, especificando los parámetros microbiológicos y químicos que deben seguirse. Las piscinas en Canadá, Alemania y Colombia tienen regulaciones o estándares específicos para parámetros microbiológicos y químicos que deben seguirse. Al igual que la regulación del agua potable, el agua debe estar libre de organismos patógenos para conservar su calidad de agua. Por otro lado, en el caso de aguas termales donde el bañista tiene condiciones similares a las de las piscinas, Canadá y Alemania no cuentan con regulaciones o normas específicas para el agua de aguas termales. En cambio, se aplican a las aguas termales los mismos requisitos microbianos y químicos que para el agua de piscinas según la Normativa de piscinas públicas de Canadá y la norma Din 19643 de Alemania. Actualmente, Colombia no cuenta con reglamentos o normas sobre la calidad de las aguas termales, tal como lo establece el artículo 6 del Decreto 554 de 2015.
Modelos transaccionales avanzados como alternativa para la implementación de transacciones de larga duración en microservicios
Authors: Candela Uribe Christian Andrés
Published: January 2023

La arquitectura de microservicios (MSA) ha ganado reconocimiento y aceptación en la industria del software, usándose cada vez más en el desarrollo de nuevos sistemas (Alshuqayran et al., 2016; Eismann et al., 2020; Marquez et al., 2018). Algunos de los motivos de su popularidad son: una base de código más pequeña que facilita el desarrollo, prueba e implementación de código más rápidos, así como la optimización de la plataforma en función del tipo de microservicio, soporte para equipos de desarrollo independientes y la capacidad de escalar cada componente independientemente (Chandramouli, 2019; Hassan et al., 2019). Sin embargo, la MSA trae consigo múltiples desafíos, entre ellos, las operaciones transaccionales donde participan múltiples microservicios representan un reto latente a las organizaciones que desean adoptar una arquitectura basada en microservicios (Di Francesco et al., 2019; Knoche & Hasselbring, 2019; Waseem et al., 2020). Lo anterior, debido a que en MSA dichas transacciones pueden involucrar bases de datos (algunas incluso sin soporte transaccional) y elementos de comunicación asíncrona. Estos últimos con duración desconocida (transacciones de larga duración) lo que hace inviable el bloqueo de registros dificultando así conocer la verdad del estado del sistema (Elmagarmid, 1992; Knoche & Hasselbring, 2019). Considerando lo expuesto anteriormente, no todas las transacciones de negocio pueden cumplir con las propiedades ACID (Dalal et al., 2003; Gray, 1981; Papazoglou, 2003; Papazoglou & Kratz, 2007; Sun & Aiello, 2007; Tang et al., 2011; Tang et al., 2006), por lo que podemos concluir que en operaciones transaccionales que abarcan más de un microservicios el modelo transaccional tradicional no es viable, siendo necesario plantear alternativas que permitan la realización de estas operaciones. Esposible buscar una alternativa en el conjunto de Modelos Transaccionales Avanzados (ATM – Advance Transactional Model) o Modelos Transaccionales Extendidos, los cuales relajan las propiedades ACID, no cumpliendo una o algunas de dichas propiedades, para soportar transacciones de larga duración (Elmagarmid, 1992; Torres et al., 2009). Este trabajo busca adaptar un MTA para su uso en MSA como alternativa para la implementación de operaciones transaccionales que involucran múltiples microservicios. Para lograrlo, metodológicamente se plantea 5 etapas: Planteamiento del objetivo, Reunión y organización de información, Diseño, Evaluación y Presentación de resultados. Estas etapas se basan en el método general de investigación referido por Sánchez (2004), además de elementos del flujo de trabajo de la investigación cualitativa descritos por Hernández-Sampieri and Torres (2018).

El estudio empezó por medio de la inspección visual a las distintas vías de la ciudad, donde se pudieron evidenciar la gravedad de las afectaciones dé los arbustos de la zona hacia la estructura del pavimento, cabe resaltar que no solo en las carreteras sino que también en los andenes se presenta esta problemática, debido a esto, se evalúa cada arbusto y se cataloga según su tipo y su característica se toma respectivamente, se captura evidencia fotografía de los arbustos donde afectan directamente al pavimento y se evalúan según el nivel de afectación que cada arbusto represente en la estructura del pavimento. Junto a esto, dicha problemática genera un impacto social negativo a la movilidad de los girardoteños, debido a las vías afectadas y afectando en general a 184.075 habitantes que transitan por dicha ciudad. Pero esta investigación no solo se concentró en catalogar los arbustos que afectan de manera negativa sino también en catalogar los arbustos que afectan de forma más leve y los que no afectan en general, dando así una clasificación de las afectaciones hacia el pavimento rígido desde el más crítico hasta el que no afecta en lo absoluto, dando ideas de que arbustos se podrían usar en un futuro para la implementación de cuerpos vegetales con pavimento y hacer que funcionen de forma armoniosa sin que ninguno de los dos salgan afectado de alguna manera.

Non-performing financing is something that is not expected by any financial institution that provides financing products because it can have a bad impact, namely losses due to a decrease in the income of the financial institution. So we need an appropriate effort to resolve the problematic financing. The formulation of the problem in this study is what are the supporting and inhibiting factors for efforts to resolve problematic murabahah financing at KSPPS BMT Mitra Umat Pekalongan Krapyak Branch in 2021 and how is the suitability of efforts to resolve problematic murabahah financing at KSPPS BMT Mitra Umat Pekalongan Krapyak Branch in 2021 with the DSN Fatwa- MUI and KHES. The type of research is sociological juridical and bottom-up research approach with data collection techniques carried out through interviews with BMT, financing supervision and several customers with financing problems and documentation. In this study used analytical descriptive analysis techniques. The results of the study indicate that  the factors that support efforts to resolve problematic murabaha financing are supervision and communication to customers; customer awareness and good faith; cooperative customer to the agreement; and the existence of a team of lawyers who provide a deterrent effect. While the inhibiting factor is the character of the customer; customer dishonesty; unstable economic conditions; and customers are reluctant to sell collateral. There are several points that are not in accordance with the provisions of the DSN-MUI and KHES fatwas, namely the points regarding debt relief at the guarantee execution stage, contract conversion points. KSPPS BMT Mitra Ummah Pekalongan Krapyak Branch does not apply any sanctions to customers who delay payments, but charges compensation for transportation costs when billing to customers' homes.
The Integration of Islamic Sciences and Secular Sciences Through Spiritualization and Humanization Approaches
Authors: Supena Ilyas
Published: January 2023

The integration of science and religion is a topic of heated debate in the Western world. Ian G Barber describes this relationship between science and religion in terms of conflict, independence, dialogue, and integration. The theme of the relationship between science and religion is not only a hot topic in the Western world, but it has also attracted the attention of several contemporary Muslim thinkers. Unfortunately, in the discourse of Islamic sciences, the object of debate is more on criticism of secular science so that it needs to be Islamized, whereas, at the same time, Islamic sciences also have serious internal problems. Using qualitative research methods by exploring authoritative text sources, this paper aims to offer a balanced perspective in viewing Western science and Islamic science. This research shows that both Western science and Islamic science have weaknesses. Western science is seen as secular science so that it loses its divine vision, while Islamic science is theocentric so that it loses its humanist vision. This finding has implications for different strategies in dealing with the two types of knowledge. Spiritualization is a strategy relevant to Western science, while humanization is a strategy relevant to Islamic sciences.

Authors: Romario
Published: January 2023

This article examines senior high school students in their search for Islamic knowledge. This study uses ethnographic methods and life stories which were carried out intensively for three months. Data was collected by interviewing eighteen students from three schools, namely MAN 1 Yogyakarta, SMA Negeri 8 Yogyakarta, and SMA Muhammadiyah 1 Yogyakarta. I took six informants from each school consisting of three students and three female students. In addition, I also made observations in observing clerics and religious content accessed by informants on social media. This article shows that high school students who are referred to as generation Z. Seek religious knowledge not only through extracurricular activities such as Rohis, but also through social media. Generation Z's consumption of religious knowledge on social media cannot be separated from the long process of Islamizing public space in Indonesia. The Islamization of this public space affects the social media space so that it gives birth to a lot of religious content and popular clerics from various different backgrounds that are liked by young people. This study demonstrates two models of consumption of religious knowledge of generation Z. First, generation Z who access religious knowledge from various ustaz backgrounds. Second, Generation Z is consistent in accessing religious knowledge on social media based on similar backgrounds, affiliations or religious organizations. This research contributes to the study of changes and developments of high school students in seeking religious knowledge.
Revitalizing the Values of Mercy Education Through Religious Education Learning in the National Curriculum in Indonesia
Authors: Abdul Hafidz Nasir
Published: January 2023

The values of mercy education become the teachings of every religion. However, these values have not been able to be realized in the daily life of students. This study aims to analyze whether the values of mercy education for each religion are the content of the religious education curriculum in schools, how the problems faced in instilling these love values in students, and how the revitalization efforts will be in the future. The research method used is literature research. Data collection techniques use documentation. The collected data were analyzed using critically performed tech s analysis.  The results showed: First, the curriculum of religious education in schools for all religions in Indonesia has contained the value of love, albeit with different sequences. Second, the problem faced is that internalizing the value of love for students has not been appropriately realized because the method used is not appropriate. Third, instilling the value of love in students in religious learning needs to be revitalized by applying more effective learning methods. Three methods are considered effective for instilling the value of love in students: habituation, exemplary, and reflective learning methods. The results showed that learning the value of love and affection in schools is only limited to recognition and this shows that learning is only focused on knowledge/cognitive aspects without paying attention to the attitude/love aspect.   Therefore, it is necessary to revitalize the cultivation process by applying more effective learning methods such as habituation, reflective, and exemplary learning.

Background/Aim: Several scoring systems have been developed to standardize radiological findings in patients with COVID-19 pneumonia. The most commonly used scoring systems in the radiological examination of COVID-19 are those of the North American Radiology Association (RSNA), British Thoracic Society (BTS), and COVID-19 Reporting and Data System (CO-RADS). However, the compatibility between these radiological scoring systems has not been evaluated before. Therefore, this study evaluated the radiological features of COVID-19 pneumonia and congruence between radiological scoring systems and determined the effect of comorbidities and demographic characteristics on radiological features and thoracic computed tomography (TCT) findings in the context of COVID-19.
Methods: A retrospective cohort study was performed on patients attending our unit with a suspicion of COVID-19 who also had a positive real-time transcriptase-polymerase chain reaction (RT-PCR) test. All TCT images were subjected to the RSNA, BTS, and CO-RADS scoring systems. Demographic data such as age and gender, and comorbid conditions were recorded.
Results: TCT showed peripheral, posterior, and bilateral involvement in 97.7%, 97.7%, and 87.6% of the patients, respectively. The most common TCT finding was ground glass appearance, which was found in 95.5% of the patients. The Charlson Comorbidity Index (CCI) score was found to have an impact on RSNA and BTS criteria (P=0.011 and P=0.014), while age, gender, and the presence of comorbidities such as cardiovascular disease (CVD), diabetes mellitus (DM), and chronic pulmonary disease (CPD) did not have such an effect (P>0.05 for all). On the other hand, CCI scores and the presence of CPD had an association with CO-RADS, but there was no effect of age, gender, DM, and CVD (P=0.915 and P=0.730).
Conclusion: TCT plays an important role in early management, isolation, and follow-up of patients with COVID-19 pneumonia. The radiological scoring systems were found to exhibit good compatibility, but comorbid conditions could have an impact on the assessment. Therefore, we conclude that these radiological assessment criteria are useful in the management and monitoring of such patients.
