Authors: Alvarado Reyes Andrés Felipe , Luna Fontalvo Jorge Alberto
Published: October 2022

Las playas por lo general son aprovechadas por el hombre realizando actividades de contacto primario mediante uso recreativo y éstas deben cumplir con los requisitos de calidad sanitaria establecidos por la normatividad competente. El objetivo de este trabajo fue determinar la calidad microbiológica del agua en tres playas del sector turístico de Santa Marta en temporadas turísticas altas y bajas. Los sitios de estudios fueron las playas de Pozos Colorados, Playa Salguero y Neguanje, los monitoreos se realizaron durante seis meses desde enero a junio del año 2019, ubicando tres estaciones en cada una de éstas. Las muestras fueron colectadas a una profundidad de 0,5 m, 1,0 m y 1,5 m en frascos plásticos estériles de 1.000 mL y posteriormente se trasladaron al Laboratorio de Calidad de Agua de la Universidad del Magdalena. Los parámetros microbiológicos evaluados fueron Coliformes Totales (CT), Coliformes Fecales (CF) y Enterococos Fecales a través de la técnica del sustrato definido Colilert®-18/Quanti Tray®. Los valores más altos de CT, CF y EF se registraron en Playa Salguero con 10,111 NMP/ 100 mL, 5,335 NMP/ 100 mL y 1,120 NMP/ 100 mL respectivamente, obtenidos en el mes de enero (temporada de vacaciones), similar comportamiento se observó para la temporada turística baja (mes de mayo). El sector de Pozos Colorados presentó resultados entre 1,700 y 2,340 NMP/ 100 mL tanto para CT, CF y EF. La playa del sector de Neguanje obtuvo los valores más bajos de CT, CF y EF en las dos temporadas (<1,000 NMP/ 100 mL). Los resultados de CT y CF obtenidos en Playa Salguero y Pozos Colorados superan los valores de referencia establecidos por la normatividad nacional vigente. La presencia de microorganismos indicadores de contaminación del agua de las playas obedece a factores como la capacidad de carga turística, vertimiento de aguas residuales y condiciones climáticas (precipitaciones).
Accounting for Wealth Concentration in the United States
Authors: Kaymak Barış , Leung David , Poschke Markus
Published: October 2022

We assess the empirical relevance of different macroeconomic modeling approaches to wealth concentration, using the joint distribution of earnings, capital income and net worth in combination with an OLG model of household heterogeneity. We find large earnings disparities to be the primary source of US wealth concentration. This reflects the fact that labor income, from salaries but also from entrepreneurship, is a major income source for top income and wealth groups in the data. Bequests and differences in rates of return on capital together explain about half the holdings of the wealthiest of households, but much less for the rest.

Published: October 2022

Background: The COVID-19 pandemic has affected blood inventory and donation worldwide. The Islamic Republic of Iran was among the first countries to report the COVID-19 pandemic and it faced a significant blood shortage during the first weeks of the pandemic. Aims: We aimed to evaluate the impact of COVID-19 pandemic on the number, type, and safety of blood donations, comparing the periods before and during the pandemic. Methods: This retrospective study evaluated data from all volunteers who attended the blood transfusion centres in the Islamic Republic of Iran from March to December 2020 (during the COVID-19 pandemic) and during the same period in 2019, i.e. pre-pandemic. Data on the number of blood collections, confirmed transfusion transmissible infection marker test results, and donor demographic information were collected from the Iranian Blood Transfusion Organization integrated donor database. Results: Total blood donations decreased by 8.38%. The number of first-time, lapsed, and female blood donors increased by 4.41%, 0.17%, and 0.90% respectively. Regular blood donation decreased by 4.58%. The distribution of the 3 main blood products, red cell concentrate, frozen fresh plasma and platelets, decreased by 7.86%. All changes were statistically significant. The prevalence rates of hepatitis C virus and hepatitis B surface antigen increased significantly during the pandemic. Conclusion: COVID-19 had a negative effect on blood safety and availability in the Islamic Republic of Iran. To improve blood supply and enhance regular blood donation, the Iranian Blood Transfusion Organization needs to reassure blood donors of the safety and hygiene measures being observed at blood collection sites.

Peranan Sel Sistem Imun Alamiah Pada Infeksi Mycobacterium tuberculosis
Authors: Wijaya Chandra , Fatmawati Fatmawati
Published: October 2022

Mycobacterium tuberculosis infection which causes tuberculosis is still a major health problem worldwide due to high morbidity and mortality, where in 2018 tuberculosis caused 1.5 million deaths. The degree of pulmonary tuberculosis varies from mild infiltration, chronic infection, cavity formation to severe and destructive tuberculosis. The difference in the degree of pulmonary tuberculosis is influenced by the response of the immune system to M. tuberculosis. When M. tuberculosis infects the lungs, the human immune system will carry out a series of processes to limit the spread and replication of bacteria. The immune system against M. tuberculosis consists of an innate immune system involving cellular components such as macrophages, neutrophils, Natural Killer (NK cells), dendritic cells and upper respiratory epithelium and an acquired immune response which is mainly mediated by T lymphocyte cells of host that is responsible for recognizing and controlling invasion by pathogens. This review will describe the role of natural immune system cells in M. tuberculosis infection. In addition, a complete description of M. tuberculosis infection will also be discussed to increase understanding of the role of natural immune system cells in M. tuberculosis infection.

Bu çalışmada Elbistan Havzası’nın jeomorfolojik gelişimine etki eden yapısal özellikler jeomorfometrik indislerle sorgulanmıştır. Sorgulamada, Elbistan Havzası’na ait 25 alt havzanın jeomorfolojik özelliklerini kazanmasında jeolojik yapı ve tektoniğin etkisi kantitatif verilerle açıklanmaya çalışılmıştır. Bu amaç doğrultusunda her bir alt havzaya drenaj havza asimetrisi (Af), transvers topografik simetri faktörü (T), havza rölyefi (Bh), rölyef oranı (Rh), havza şekli indeksi (Bs), hipsometrik eğri (Hc) ve hipsometrik integral (Hi) gibi jeomorfometrik indisler uygulanmıştır. Uygulama esnasında 10x10 metre çözünürlüklü Sayısal Yükseklik Modeli, jeoloji verisi, aktif fay verisi ile Coğrafi Bilgi Sistemi yazılımlarından ArcGIS 10.7 paket programı kullanılmıştır. Havzaya uygulanan indislerden (Af, T, Bh, Rh, Bs, Hc ve Hi) elde edilen kantitatif veriler birbirleri ile tutarlı sonuçlar vermiştir. Yani alt havzalarda tektoniğin etki derecesine göre yapılan sınıflandırmalar esas alındığında genellikle aynı alt havzaların aynı grupta yer aldığı görülür. Bununla birlikte yakın lokasyonda yer alan alt havzalar da çoğunlukla aynı sınıflarda yer almıştır. Dolayısıyla jeomorfometrik indislerden elde edilen verilerin tamamı fayların geçtikleri alanlardaki alt havzaların formlarına farklı derecelerde etki ettiğini destekler niteliktedir. Elbistan Havzasın’da alt havzaların farklı formlarda olmasında aktif tektonik ve litoloji önemli rol oynamıştır.

¿Can the stock market boost economic growth?
Authors: Razo-De-Anda Jorge Omar , Cruz-Aké Salvador , Venegas-Martínez Francisco
Published: October 2022

This paper develops a stochastic dynamic general equilibrium model to assess the impact of Real Estate Investment Trust (REIT) in the growth rate of the real estate sector through direct investment in infrastructure. Based on the theoretical relationships that the model provides we show empirical evidence, through a quantile econometric analysis of time series, of the positive impact of the REITs in the construction sector. The growth in the construction sector comes from the demand for real estate by those trusts, which would lead to a price increase, promoting gross fixed capital formation, and increasing the value of output in the construction industry.

Published: October 2022

The purpose of this study is to analyze the working capital management (WCM) strategies followed by non-financial firms listed in the IPC during the Covid-19 economic crisis, by estimating the target level of working capital requirements. We classify firms by operations in different geographies. Then we employ a regression analysis of random effects to estimate the working capital requirements (WCR) of the different firms, by regions, to understand the strategies of WCM. The study was conducted for the period 2018q1-2020q2, for which we have data available but also comparison for normal times (2018q1- 2019q4) vs Covid-19 times (2020q1-2020q2). The contribution is to describe the WCM practices in Mexico, because of the lack of studies of this kind, but also to analyze these practices in periods of economic crisis, where the working capital use to be high. The conclusion is that the WCR are related to the gross margins, but also that firms that have operations in locations different than Mexico have a better WCM.

Published: October 2022

Esta investigación tuvo como resultado aplicar herramientas de minería de datos y elaborar indicadores, para estimar la conveniencia fiscal de la incorporación de la economía informal al régimen tributario y su impacto en el crecimiento de la economía en México. La incorporación de la economía informal dentro del régimen tributario es un problema a nivel mundial, y no se han dado los parámetros a seguir por las conveniencias e inconveniencias que se presentan para su incorporación formal, provocando con esto un desperdicio de recursos económicos que podrían ayudar a aumentar los ingresos impositivos de un país y lograr finanzas públicas sanas para un crecimiento económico sostenido en las economías. Dentro de las finanzas públicas, la importancia de administrar adecuadamente los ingresos y egresos de un país es de vital importancia, ya que, en estos, se sustenta su sana economía, que le permitirá contar con finanzas públicas sanas, para su adecuado desarrollo económico, por lo que si no se recaudan los ingresos necesarios (vía impuestos) tendrá serios problemas para su viabilidad económica, como país. En el caso de México se encuentra con problemas significativos en la recaudación de sus ingresos impositivos, ya sea porque su base impositiva no es suficiente, o porque hay problemas con la evasión fiscal. Esta investigación le permite al estado detectar qué papel juega la economía informal, y cuanto podría aportar a las finanzas públicas. Esta investigación baso la hipótesis, en la propuesta de que, sí se elaboran y aplican herramientas de minería de datos, para detectar los ingresos en la economía informal, entonces el Sistema de Administración Tributaria (SAT) podrá mejorar su recaudación impositiva. El método utilizado para probar esta hipótesis de investigación consistió en la aplicación de la minería de datos a las estadísticas de economía informal, y elaborar indicadores. Se concluye que la incorporación de la economía informal, podría mejorar la captación de ingresos impositivos.

Published: October 2022

Teacher education is one of the key strategies to enhance higher education quality and transform from traditional education to 21st-century-oriented higher education in Bangladesh. This paper evaluates the experiences of the Post Graduate Diploma in Higher Education Teaching (PGDHET) program gained through the journey toward developing a higher education teacher professional development program and implementing it. This six-month-long program, titled Post Graduate Diploma in Higher Education Teaching (PGDHET), was launched by the Bangladesh University of Professionals (BUP). The key themes and elements of this teacher education program were academic program and curriculum, teaching-learning in higher education, professional practices in higher education, the well-being of students, ICT in higher education, assessment, research, and supervision in higher education. It offered a focused pathway for quality assurance activities, which is crucial in reinforcing and strengthening a culture of quality teaching-learning in Bangladeshi universities. A comprehensive, rational approach was adopted for developing this paper. Both authors were involved in the development of this program, so their voices were considered a valuable source of data. Their journal entries and conversations with various stakeholders were the primary data collection methods, whereas an intensive review of 86 higher education teaching-learning program programs offered by 80 universities on six continents around the world was supportive of understanding the global trends in tertiary teacher education programs. The analysis revealed that developing such a comprehensive program for tertiary teacher development was not an easy task, as many issues and complexities were involved, like the duration, vision and mission, design, and assessment guidelines during the development phases. The challenges were multifaceted and multidimensional, such as fitting the program content to be applicable across the teaching disciplines and ensuring its suitability for those teaching in face-to-face, flexible, and online learning environments.

Published: October 2022

The need for optical fibers has emerged for their ability to transmit information with less attenuation over long distances. This work studies four optical fibers with core radii from 1 µm to 4.75 µm in steps of 1.25 µm and a numerical aperture of 0.17. furthermore, The mode properties were calculated at a wavelength of 633 nm by using RP Fiber Calculator (free version 2022). Also, the effect of increasing the core radius on the studied properties has been studied. Multimode fibers can be obtained when the radius of the fiber core is large compared with the fiber's operating wavelength, which is less than the cutoff wavelength of the mode. Moreover, single-mode fiber is obtained. It has been concluded that all the calculated properties increase with increasing core radius, and More than half of the power is contained in the core. Finally, Intensity profiles of all modes were illustrated.

Green Synthesis of IONPs for Photocatalytic Activities
Authors: A. Khamees Husam , A. Abid Muslim
Published: October 2022

To make iron oxide nanoparticles (IONPs), a simple chemical approach was used to combine iron chloride (FeCl2+FeCl3) salt with onion peel extract. According to the study, iron salts can be converted into IONPs by the biomolecules in onion peel extract. From FeCl2+FeCl3 to γ -Fe2O3, the approach changes iron oxide NPs' size, shape, purity and phases. In water treatment, γ -Fe2O3 NPs are critical for the removal of the color methylene blue (MB). X-ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet (UV-Vis) and photoluminescence (PL) spectroscopy were used to identify IONPs. Results from the XRD experiment showed crystals having a tetragonal structure have average size of 13.4680 nm for γ- Fe2O3 NPs with a chemical method. Tetragonal diffraction peaks were observed in the data, and excellent crystal quality in a cubic shape. In the simple chemical process, the grain size was around (23.9 to 169.4) nm and average grain size 76.6 nm. UV-VIS measurements showed that the energy gap value had shifted to the blue from 1.94 to 2.96 eV in the simple chemical method.PL spectroscopy showed that the near band edge emission of γ-Fe2O3 NPs with a simple chemical approach was roughly 2.65 eV. NPs photocatalytic activity was as evidenced by the breakdown of MB dye when exposed to a moderate amount of light, as shown in this study. The results show that the synthesized material is of high quality γ-Fe2O3 NPs, with greater degrading efficiency when made using a simple chemical method, reaching 89.2% at 75 minutesfor 3 mg and 91.1% at 150 minutes for 5 mg, with a high level of photocatalytic efficacy the γ-Fe2O3.

Lignin degradation by co-cultured fungi: current status and future perspectives
Authors: Castro Soares Jullio Kennedy , Valle Vitali Vera Maria , Afonso Vallim Marcelo
Published: October 2022

The lignocellulosic biomass is a highly abundant and renewable resource. However, its exploitation is limited by the recalcitrance of the lignin present in the plant cellwall. In the last three decades, fungal co-cultures have increasingly been applied to overcome lignin recalcitrance by enhancing the production of ligninolytic enzymes through microbial interactions. In this paper, we systematically compile studies on fungal co-cultures used in the degradation of lignin-containing substrates to clarify the advantages and limitations of this type of culture. Based on their different delignification rate potentials, co-cultures can be classified into synergistic, antagonistic, and neutral. Co-cultivation results are generally related to the balance or imbalance of antagonistic and synergistic effects arising from the specific compatibility between the species during the interaction. It is well known that the paired species and the microenvironmental system conditions are responsible for the reported degradations,however, the mechanisms underlying these interactions remain poorly understood. In conclusion, literature results demonstrate the promising application of fungalco-cultures in biotechnological sectors to improve the degradation of lignin and its derivatives, through their better understanding of the efficient exploitation ofbiological resources on ecological and industrial scales.

The Increase in the Commissioning of Paintings during the Late Joseon Period and Its Impact
Authors: Lee Yeonju
Published: October 2022

The late Joseon period witnessed significant growth in the commissioning of paintings. This increased demand for paintings, which led to changes in the production and consumption of paintings, is evidenced by the increased number of painting inscriptions that specified the names of clients. Those painting inscriptions indicate that the client placed an order to the painter in person, via a broker, or through correspondence. They also reveal which pictorial subjects were particularly favored by clients. For instance, demand for paintings of true-view landscape of the client’s family hometown or of famous scenic places was particularly high among scholarofficials, and yet demand for conceptual landscape paintings still remained high. The portrait was emblematic of the genre of paintings that were to be commissioned first. Aspirations to take pleasure in Chinese literati culture were expressed in the consumption of narrative figure paintings. The subject of immortals, which symbolized the wish for longevity, and the subjects of flowers, plants, birds, and animals, which served as auspicious decoration, also gained currency as the basis of demand for painting broadened. The terms of commissioning paintings as formed in the late Joseon continuously shaped the painterly practice even after the fall of the Joseon, heralding the way paintings were distributed and consumed in modern Korea.
Changes in the Iconography of the Attributes in the Thousand-handed Avalokiteśvara Paintings According to Scriptural Bases : Focusing on the Iconographies from the Tang to the Ming Dynasty
Authors: Moon Sang-leun
Published: October 2022

Following the introduction and spread of scriptures of the Thousand-handed and Thousandeyed Avalokiteśvara bodhisattva in China, around seventy paintings of Thousand-handed Avalokiteśvara were produced since the late Tang period. There exist numerous studies on the attendants of the Thousand-handed Avalokiteśvara in different types of paintings, but the attributes of the bodhisattva have not been considered in depth.
Therefore, I have analyzed how the attributes of the Thousand-handed Avalokiteśvara were described in the canonical scriptures—namely, Qianshou qianyan Guanshiyin pusa guangda yuanman wuai dabei xin tuoluoni jing(千手千眼觀世音菩薩廣大圓滿無礙大悲心陀羅尼經), translated by Bhagavaddharma, Qianshou qianyan Guanshiyin pusa dabei xin tuoluoni(千手千眼觀世音菩薩大悲心陀羅尼) and Shewuai dabeixin da tuoluoni jing(攝無礙大悲心大陀羅尼經), both translated by Amoghavajra, and Qianguangyan Guanzizai pusa mimi fa jing(千光眼觀自在菩薩祕密法經) translated by Sanmeisupoluo(三昧蘇嚩羅),—and categorized the paintings by the scriptures they were based on. By studying nineteen paintings made in the period from the Tang to the Ming Dynasty, whose attributes could be clearly discerned, I discovered that the differences in the attributes depicted in the paintings are neither temporal nor geographical, but resulted from the base scriptures.
Conclusively, this study is significant as it proposes a new criterion for the study of the Thousand-handed Avalokiteśvara iconography.

Published: October 2022

Background: Atrial Fibrillation (AF) is a major cause of stroke. Oral anticoagulation can reduce the risk of AF-associated stroke by 65% but it remains underused. Stroke prevention therapy in patients with AF has been considered a good target for shared decision making with patient decision aids as it is a long-term, preference-sensitive decision with known risk-benefit trade-offs. The aim of this systematic review was to summarize published literature on the effectiveness of patient decision aids on the choice of and adherence to stroke prevention therapy in individuals with AF. Methods: We conducted a structured literature search for prospective studies evaluating decision aids for AF stroke prevention therapy in adult patients with nonvalvular AF. We included studies that compared those exposed to a decision aid with a control condition for outcomes including choice of therapy, adherence, decisional conflict and patient knowledge. Quantitative meta-analysis was not feasible due to excessive between-study heterogeneity. Results: Eight studies met inclusion and exclusion criteria. Six studies were randomized clinical trials and two were pre-post comparisons. Of the 8 studies, each evaluated a different decision aid, with only three including all contemporary oral anticoagulant drugs. All decision aids improved AF knowledge compared to baseline or control and decision aids reduced decisional conflict in four of six studies. However, there were inconsistent effects of the studied decision aids on initiation of oral anticoagulation. Adherence to initial stroke prevention therapy choice appeared to benefit from decision aid use in 2 studies that addressed this issue. Conclusions: Decision aids for stroke prevention increased AF patients’ knowledge and decisional confidence but had variable impacts on choice of and adherence to stroke prevention therapy. The results highlight the need for well-designed decision aids that present patients with all contemporary therapeutic options.
