Published: March 2023

A través del paso del tiempo han surgido alternativas para la generación de energía, una de ellas es la celda de combustible microbianas, mediante este método se aprovecha la energía residual de los microorganismos, sin embargo, ha presentado deficiencias en su aplicación debido al rápido uso del sustrato por parte de los microbios para generar energía eléctrica. En este artículo se propone la implementación de celdas de combustible microbianas de plantas, las cuales agregan microorganismos al sistema de generación de energía y a través del proceso de fotosíntesis propician una interacción benéfica para el sustrato, permitiendo conservar sus propiedades, necesarias para la generación de energía eléctrica. Para almacenar la energía generada por la P-MFC es necesario conocer el comportamiento del voltaje, para así desarrollar el método más eficiente de recolección de energía diseñando un dispositivo de menor tamaño, dando la posibilidad crear un prototipo menos invasivo para la planta.

Recognition of the usefulness of drama subtitles: Focusing on listening learning
Authors:   The Research Society for the Korean Language Education, Sohn Ji hye
Published: March 2023

The purpose of this study is to find out the perception of usefulness that intermediate and advanced Korean learners feel in Korean listening learning according to the type of drama subtitles through surveys and interviews. The types of subtitles were set to three: learners’ native language, Korean, and no subtitles. Learners were classified according to characteristics such as native language, age, and learning period, and the effect of each characteristic on the perception of usefulness of subtitles was examined. In addition, by conducting interviews related to subtitles with Russian learners, the usefulness of subtitles in listening learning was deeply investigated. As a result of the analysis, the average recognition of Korean subtitles was significantly higher in the group using Korean subtitles than in the group using subtitles in their native language and no subtitles. Native language did not have a significant effect on recognition according to subtitle type, and it was confirmed that there was a rather high correlation between age and the usability of native language subtitles. This study is meaningful in that it can be used to determine the selection of subtitles to be used and the timing of providing subtitles in future classes using video materials.

Biotransformation of the antiproliferative (E)-2-[(4’-methoxyphenyl)methylene]-benzosuberon-1-one (2c) was studied using rat liver microsomes. As a result of the CYP-catalyzed transformations, one monooxygenated (2c+O) and the demethylated (2c-CH2) metabolites were identified by HPLC-MS. (E)-2-[(4’-methoxyphenyl)methylene]-benzosuberon-1-ol, the expected product of rat liver microsomal carbonyl reductase, was not found in the incubates. Microsomal GST-catalyzed reaction of the compound resulted in formation of diastereomeric GST-conjugates. Under the present HPLC conditions, the diastereomeric adducts were separated into two chromatographic peaks (2c-GSH-1 and 2c-GSH-2).

Physiotherapy, as a health profession, has its own ethical perspective derived from its specific activities, with its particular ethical problems and dilemmas. It has been observed that there is a lack of bioethics content during university training for this degree. Based on this, the objective of this study is to find out the methodology of teaching ethics in physiotherapy. For this purpose, a bibliographic review is made in databases that include the teaching methodologies used in physiotherapy students. Six articles were included for analysis. The results obtained show variability in the methodologies, samples and assessment tools. Although similarities are found in terms of teaching in small groups, bioethics teaching and clinical practice are carried out at the same time and the use of clinical cases with qualitative analysis of the narrative generated by the students

Published: March 2023

Aging is a complex, multifactorial process, which involves changes at physical, emotional, psychological and social levels in people. Institutionalized elderly patients usually have a degree of frailty and a tendency to dependence, both biologically, as well as functionally and socially. It is for this reason that this type of patient requires a series of care with a marked integrative nature, rehabilitative and therapeutic, among others. According Person-Centered Care aims, this article presents an intervention project based on Narrative Gerontology, to elaborate the Life Stories of several patients of a nursing home in Tenerife, searching for the improvement of their state of mind and the subsequent design of nursing activities and interventions loaded with meaning for each of them.

Published: March 2023

Metal-catalyzed C-H bond annulation strategy offers a versatile platform, allowing the construction of complex p-chiral molecules through atom- and step-economical fashion. However, regioselective insertion of -coupling partner between M-C bond and high enantio-induction remain elusive. Using commercially available Co(II) salt and chiral-salox ligands, we demonstrate an unorthodox protocol for the regio-reversal, enantioselective C-H bond annulation of phosphanamide with bromoalkyne through asymmetric desymmetrization. This method was accomplished by sequentical C-H bond activation, regioselective migratory insertion, reductive elimination, and ligand exchange with carboxylate, which resulted in the formation of novel P-stereogeneic compounds with good substrate scope and high ee (up to 99% ee). The isolation of reactive intermediates involved in the catalytic cycle and the outcomes of control experiments provide support for a plausible mechanism.

Laser desorption ionisation (LDI) is generally considered to be an inferior ionisation modality to matrix assisted LDI (MALDI), providing information solely on lipids with low sensitivity. The current study demonstrates that the combination of ambient LDI with in-source surface-induced declustering provides sensitivity and chemical coverage comparable to MALDI. The setup was characterised for infrared laser desorption using two different laser systems and was successfully used for ambient mass spectrometric imaging. 20 µm spatial resolution was achieved with oversampling, approaching single-cell resolution, while metabolites and lipids ranging from amino acids through carbohydrates and nuclear bases to complex glycolipids were successfully detected. The technique was also tested as a platform for MS-guided surgery, raising the possibility of using a single technique for generating histological and in-vivo data. The results suggest that the new method can form the basis for a new histological classification system for surgery and pathology environments closing this 150 year old diagnostic gap.

Published: March 2023

Nonconventional luminescent polymers (NCLPs) have attracted considerable attention due to their unique luminescence behavior. Although various routes can be employed to synthesize such vinyl-based NCLP, the dependence of their photophysical properties on the polymerization method used and thus potential small variations of the overall macromolecular architecture is rarely reported. In this study, we have investigated in detail the luminescence behavior of polyacrylonitriles (PANs) synthesized with two different polymerization methods, namely by free-radical polymerization (FRP), and reversible addition-fragmentation chain transfer (RAFT). Dependent on the polymerization route and initiator used, the PANs show distinct PL and excitation wavelengths, and their emission covers a wavelength range from 400 to 630 nm, respectively. Moreover, the synthesized PANs easily can be homogeneously blended both in solution and solid states, and the resulting emission is a superposition of the emission of the blend components. This study provides a facile approach to tune the photophysical properties of PANs and related vinyl-based NCLPs and provides new fundamental insight to further booster application development of NCLPs.

Впервые методом спонтанной кристаллизации из раствора получены крупные монокристаллы высокоэнтропийных оксидов со структурой гексаферрита М-типа, химический состав которых может быть описан формулой BaFe12-x(Ti,Mn,In,Ga)xO19. Определены фактические составы полученных образцов: BaFe1.20Ti0.22Mn0.76In0.58Ga0.23O19, BaFe8.71Ti0.44Mn1.16In1.25Ga0.44O19, BaFe7.14Ti0.57Mn1.77In1.79Ga0.73O19, BaFe5.6Ti0.64Mn2.48In2.52Ga0.76O19. Полученные кристаллы имеют характерную для гексаферритов форму и характеризуются достаточно равномерным распределением элементов в их структуре. Установлено существенное количественное различие в способности ионов различных металлов переходить из расплава в растущий кристалл. При этом изменение исходной концентрации ионов в растворе практически не оказывает влияния на способность ионов переходить в растущий кристалл. Изучено влияние состава кристаллов на параметры их кристаллической решётки. Некоторый рост значений этих параметров коррелирует с уменьшением содержания железа в образцах. Главным образом это объясняется повышением средневзвешенного ионного радиуса ионов, образующих кристаллы. Рассчитаны и сопоставлены значения конфигурационной энтропии смешения в рамках подрешётки, образованной Fe, Ti, Mn, In и Ga, для целевых составов и составов фактически полученных кристаллов.
Sistemas Apostilados de Ensino e Autonomia Docente: Uma Análise com Professores de Ciências da Natureza e de Matemática em Escolas Privadas do Rio Grande do Sul
Authors: Ortiz Gabriel Santos , Denardin Luciano
Published: March 2023

Este artigo apresenta os resultados de uma pesquisa qualitativa que teve como objetivo compreender como os Sistemas Apostilados de Ensino (SAEs) têm interferido na autonomia de professores de ciências da natureza e de matemática em escolas da rede privada do Rio Grande do Sul. Com esse intuito, realizaram-se entrevistas semiestruturadas com dez professores de diferentes escolas do estado. Analisou-se o corpus por meio da Análise Textual Discursiva (ATD) aliada à construção teórica sobre autonomia docente de José Contreras. As categorias finais emergentes do processo foram: Persuasão (resultados e comunicação); Materiais e Recursos Didáticos; e Planejamento e Direcionamento. Os resultados indicam a presença de diversos fatores que afetam diretamente a prática pedagógica do corpo docente ou que camuflam, por meio de um discurso de flexibilização, o controle ao qual os professores estão submetidos. Também, aliados ao que já vem sendo exposto na literatura, fornecem indícios de que a racionalidade gerencialista dos SAEs vem intensificando o processo de proletarização ideológica dos professores ao mesmo tempo em que dissimula seu controle por meio de mecanismos mais sutis que induzem a uma autonomia ilusória e atenuam movimentos de resistência. Nesse sentido, os entrevistados parecem assumir uma função profissional muito mais técnica e reprodutiva do que crítica e participativa.
Edge Networks the Future of Cloud Computing

Published: March 2023

Computing architecture continues the pendulum swing between centralized and distributed models – driven by technological innovation in CPU/GPU architecture, memory/storage, I/O, networking, performance, and emerging use cases. For a number of years, the most recent architecture has been the cloud-based centralized computing model, which is now shifting to a distributed edge computing model. New businesses, technologies, usage models, and new applications are driving this change. The rapid growth of IoT across all segments of society is driven by 5G, Edge, low-cost sensors, embedded SoC controllers, and new enterprise applications. The impact is more data being generated by these smart sensors, increased demand for storage, data analytics, and network capacity to move this data to adjacent nodes or cloud models. These and other parameters are driving the emergence of the Edge computing model – and there are many Edge types. However, in terms of optimisation and efficiency, these approaches may not be the best solution.
Infrastructure Development of Non DHT-Based Pyramid Tree Network Architecture

Published: March 2023

In this paper, we have considered a recently reported 2-layer non-DHT-based structured P2P network. It is an interest-based system and consists of different clusters such that peers in a given cluster possess instances of a particular resource type. It offers efficient data look-up protocols with low latency. However, the architecture lacks in one very important aspect: it is assumed that no peer in any cluster can have more than one resource type, and this could be a very hard restriction practically. This is true for all interest-based works existing in the literature. Therefore, in the present work, we have addressed this issue of generalizing the architecture to overcome this restriction and so far, have come up with some significant initial results. Work is being on to complete the generalization process. We have identified some of our previously reported data look-up protocols that will need to be modified in order to accommodate the new findings toward the generalization and while doing so, we aim at keeping the data look-up latencies of these probable modified protocols unchanged. In addition, our objective is to consider security in communication in the generalized architecture as well. To achieve it, we aim at using mainly public key-based approach for the different look-up protocols reported earlier, because results obtained so far in this direction indicate that the required number of public-private key pairs will be much smaller than the number of symmetric keys if symmetric key-based approach is used.

Published: March 2023

One method to reduce vehicle congestion in a road traffic network is to appropriately control traffic signals. One control scheme for traffic signals is a distributed control scheme in which individual traffic signals cooperate locally with other geographically close traffic signals. Deep reinforcement learning has been actively studied to appropriately control traffic signals. In distributed control, it is important to select appropriate cooperative partners. In this study, we propose a method for selecting appropriate cooperative partners using deep reinforcement learning to the distributed traffic signal control.
Viability of Machine Learning in Android Scareware Detection
Authors: Gautam Aayush , Rahimi Nick
Published: March 2023

With the rapid increase in the use of mobile phones and other technologies, there has been a proportional growth in malware that tries to collect sensitive user data. Android is the most popular operating system for smartphones and has a great potential of becoming a target for malware threats. Scareware is a type of malware that tries to get users to provide valuable information or download malicious software through social engineering. This research aims to find out if machine learning is a viable option to prevent the consequences of scareware by accurately detecting them. In this investigation, four supervised machine learning (ML) algorithms were used in a dataset called CICAndMal2017 with 85 attributes for each of 11 Android scareware families and benign samples. We were able to achieve an accuracy of 96% which helped us to conclude that machine learning can and should be used to detect scareware. The machine learning models were then tested to calculate the accuracy for classifying each scareware family.
A Stock Recommendation System
Authors: Singh Jashanjit , Jenq John
Published: March 2023

One of the most difficult analyses of all time is stock market predictions. Expert analysts and software engineers are collaborating to create a stable and reliable platform for predicting future stock value. The fundamental difficulty is that a variety of factors will influence the price fluctuations. Stock recommendations are vital for investment firms and individuals. However, no unique stock selection approach can capture the dynamics of all stocks without adequate analysts. Nonetheless, the majority of extant recommendation techniques are built on prediction algorithms ANN (Artificial Neural Network) to buy and keep high-yielding companies. We offer a unique strategy in this paper that uses reinforcement learning to recommend a stock portfolio based on the Yfinance data sets. We will present an ARIMA framework for recommendation systems, as well as a foundation for determining the system's value. Within this paradigm, we do probabilistic studies of algorithmic approaches. These studies illustrate the value of recalling earlier activities and examines how this recollection may be used.

Efficiency of Glyphosate in the control of Spermacoce verticillata L. in different development stages
Abstract
Spermacoce verticillata L., known regionally as vassourinha-de-botão, it is a weed species that has been causing serious damage to upland pastures in the Amazon. It is possible to verify in the region huge areas of pastures almost totally dominated by S. verticillata, which suppresses the growth of planted pastures and other native species. The objective of this work was to evaluate the efficiency of different doses of glyphosate in controlling S. verticillata at different growth stages. The experimental design used was completely randomized, in a 5 x 4 factorial arrangement (five increasing doses of the herbicide glyphosate: 0; 960, 1.920, 2.880 and 3.840 g ha-1 of area (acid equivalent), and four stages of broom growth -de-button: 60, 90, 120 and 150 days after emergence), with 10 repetitions. The characteristics evaluated were: plant height (cm), shoot dry matter (g) and mortality percentage (%). All doses from 960 g ha-1 of glyphosate a.e. were efficient in the control of S. verticillata. Plants aged between 60 and 90 days were more susceptible to herbicide doses. It is recommended to use a dose of 960 g ha-1 of glyphosate a.e., applied within 90 days after the emergence of S. verticillata.

A coleta de dados foi feita por meio de grupo focal, aplicando-se uma entrevista semiestruturada a um grupo de sete participantes, sendo os dados submetidos à Análise de Núcleo de Sentido, com auxílio do software IRAMUTEQ. Os resultados constataram que as redes sociais digitais mais usadas pelas participantes foram o WhatsApp e o Facebook, motivadas pela curiosidade e a necessidade de se adequarem à modernização da informação e comunicação. No que tange as contribuições sociais da pesquisa, tem-se que o uso destes canais/redes digitais promove o bem-estar dos usuários, à medida que proporciona uma aproximação no contato com amigos e familiares, diminuindo sensações de solidão. A partir de então, gerencialmente, pode-se pensar em práticas que possam refletir em um envelhecimento saudável, com o auxílio das redes, que conectam, e fornecem uma pluralidade de possibilidades.

Sosyal Bilimlerde kullanılan kavramların tanımlanması, kullanım alanlarının ve işlevlerinin ortaya konulması; bu kavramların açığa çıkardığı olumlu ve olumsuz dışsallıkların tespit edilmesi, bu kavramların kullanıldığı bilimsel çalışmaların
anlaşılırlığı ve daha fazla kişiye ulaşması açısından önem arz etmektedir. Bu çalışmada 1990’lı yıllardan günümüze kadar başta sosyoloji alanı olmak üzere birçok sosyal bilim dalında gün geçtikçe daha fazla sayıda bilimsel çalışmaya
konu olan ve günümüzde yoksullukla mücadeledeki etkisi tartışılan “sosyal sermaye” kavramı inceleme konusu edilmiştir. Önce 19.yüzyıl düşünürlerince ardından da Jacobs, Hanifan, ve Loury gibi araştırmacılar tarafından çözümlenen
sosyal sermaye kavramına olan ilgi 1980’li yıllardan itibaren Bourdieu ve Coleman gibi sosyologlar ve siyaset bilimci Putnam’ın çalışmaları ile hız kazanmış, ardından bu ilgi sosyal bilimlerin diğer alanlarına da yayılarak çok
sayıda çalışmaya konu olmuştur. Sosyal sermaye kavramı, 1980’li yıllardan önce makalelerde anahtar kelime olarak toplamda 20 defa kullanılmasına rağmen, yayınlanan çalışmaların sayısı gittikçe artarak 1991-1995 aralığında 109’a
ve 1996-1999 yılları arasında da 1003’e yükselmiştir. Dünya Bankası’nın toplumların kalkınmasındaki rolü nedeniyle sosyal sermaye kavramına verdiği önem ve IMF ve UNDP gibi uluslararası kuruluşların kalkınmada bu kavrama atfettikleri
işlevlerin etkisiyle, 2000’li yıllarda kavram, araştırmacıların ilgisini çekmeye devam etmiş ve kavram ile ilgili literatüre yapılan katkıların yükselişi devam etmiştir. Bu çalışma boyunca sosyal sermaye kavramının ifade ettiği
sosyal gerçekliğin tarihsel açıdan hangi kavramlarla ifade edildiği, sosyal sermaye kavramını ele alan sosyal bilimcilerin bu kavramı hangi bağlamlarda ele aldığı, sosyal sermaye kavramının ne tür işlevler görebileceği, sosyal
sermaye kavramının hangi eleştirilere maruz kaldığı ortaya konulmaya çalışılmıştır.

faaliyetlerinin yapıldığı, kurumsal projelerin gerçekleştirildiği ve önemli günlerde gerçekleştirilen sergilerin düzenlendiği sonucuna ulaşılmıştır. Kurum çalışanlarını devamlı öğrenmeye yönelik yapılan etkinliklerin hizmet içi
eğitim faaliyetleri, kurumsal yapının değişimi (geri dönüşüm kütüphanesinin açılması), kurumsal proje ve sergilerin düzenlendiği ortaya çıkmıştır. Öğretmenler düşüncelerine kurumda değer verildiğini ve farklı düşüncelere saygı
duyulduğunu belirtmişlerdir. Farklı bakış açılarının önemsendiği sonucuna ulaşılmıştır. Okul vizyonunun bireylere geleceğe yönelik meslek kazandırmak, her yaşa ve herkese eğitim, yeniliğe ve teknolojiye açık, öğrenmeyi destekleyen
bireyler yetiştirme, bireylerin geleceğe yönelik ihtiyaçlarını karşılamak, kurumsal tanıtımı arttırmak ve kaliteyi yakalamak, topluma yararlı, kendini iyi ifade eden ve özgüven sahibi bireyler yetiştirmek, Türk kültürünü halk benimsetmek
şeklinde olduğu sonucuna ulaşılmıştır. Kurum çalışanlarının takım çalışmasına katılımı üst düzeydedir. Kurumda oluşan problemlerin çözümünde yönetici ve öğretmenlerin öncelikle iletişimi kullandıkları daha sonra da resmi yollara
başvurdukları tespit edilmiştir. Okuldaki problemlerin çözümünde birlikte problem çözme becerisi büyük ölçüde uygulanmaktadır.
A ‘Stranger’ Between Spatial and Spiritual (Hyper) Reality: The Quest for Meaning in Haig’s The Humans

Rus Edebiyatı’nın önde gelen isimlerinden birisi olan Lev Nikolayeviç Tolstoy, dünya genelindeki birçok yazar, düşünür ve aydın ile hayatın anlamını arama ve anlamsızlıklar içinde derin ruhsal çöküşlere maruz kalma kaderini yaşamıştır.
Tolstoy, Anna Karenina’yı tam böyle bir süreçte kaleme almış ve dini hassasiyetlerinin artmaya başladığı dönemde İnsan Ne ile Yaşar? ile bu sorgulamayı tam anlamıyla zirveye taşımıştır. İnsanda ne var? İnsana ne verilmemiştir?
İnsan ne ile yaşar? şeklindeki üç soruya cevap arayan bir meleğin dünya üzerinde insanlar ile olan münasebetlerinden yola çıkarak oluşturulan hikâye insana dair mana arayışının en önemli eserlerinden birisi haline gelmiştir. Aynı
arayış farklı eserlerde ve farklı biçimlerde devam etmiş ve birçok edebi eserin de merkezinde yer almaya devam etmiştir. Bu şekildeki romanlardan birinin yazarı olan Matt Haig’in İnsanlar adlı eseri de yine bir mana arayışı ve
sorgulamanın kitabıdır. Vonnadorya adlı bir alemden dünyaya gelen bir yabancı (uzaylı) insanoğlunun matematik ile ilgili hayati bir formülün nihayete ermesine engel olmaya çalışır. İnsan kılığında dünyaya gelen bu uzaylı, dünyada
geçirdiği zaman diliminde kurgusal olarak önemli olaylar yaşarken, aynı zamanda kendisini bir anlam arayışının da içinde bulur. Bu yönüyle de önemli bir neticeye varan bir arayış romanı kurgulanır. Söz konusu çalışma, bu gerçeklikten
hareketle İnsanlar’ı bir anlam ve insanlığın özünü sorgulamaları ile ele almış ve Tolstoy’dan yola çıkılarak felsefi ve düşünsel arka planlarını da göz önüne alarak, İnsan Ne ile Yaşar? ile birlikte bir arayış romanı olarak incelenmiştir.
