Published: May 2022

Objective: This study aims to identify the nursing students' opinions about the COVID-19 vaccine.Materials and Methods: This descriptive, cross-sectional study was realized with 1008 students enrolled in the nursing departments of four universities located in Istanbul. Data were collected online with Information Form.Results: 85.7% of the students did not get a COVID-19 vaccine, and 44.8% of the unvaccinated students did not think about getting a vaccine or were indecisive. The reasons for the students' not thinking about getting the vaccine or their indecisiveness about it were most frequently the vaccine having been produced in a very short time, not trusting the protection or content of the vaccine, not having enough information about the vaccine. A significant difference was found between the students’ grade (p= 0.000), type of university (p= 0.000), knowledge level about the COVID-19 illness (p= 0.028) and vaccine (p= 0.000) and their thinking about getting vaccinated.Conclusion: It was found that a tiny part of the students was vaccinated; almost half of the unvaccinated students did not think about getting vaccinated or were indecisive. Understanding the student's perspective on the COVID-19 vaccine can be helpful in planning multidisciplinary education strategies.

Organizational Strategic Response in Implementing the Indonesian ISFAS 109 on Accounting for Zakat: Case of Amil Zakat Agency in Bali
Authors: Prayudi Made Aristia , Sofyani Hafiez
Published: May 2022

This study addresses an issue of the alternative strategic responses, rather than compliance, to institutional pressure take by a public organization. This study aims to investigate why and how zakat management organizations strategically respond to comply or not to comply with the Indonesian Statement of Financial Accounting Standards of 109 (ISFAS 109) concerning Accounting for Zakat. This study was conducted in National Amil Zakat Agency in Bali, and it applies a case study method with interviews, observation, and document review as data collection techniques. The data were interactively analyzed by applying thematic analysis. The results showed that although a majority of the financial reporting processes could reflect the choice of acquiescence responses (compliance) to the ISFAS 109, other findings revealed the existence of non-compliance responses (compromise-balancing). These non-compliance responses were relating to the context of receiving non-halal funds and the related parties' transactions. It is also found that the existence of this non-compliance behavior can be attributed to the low level of both organizational dependence on its constituents and coercivity of the institutional pressure. This study contributes theoretically by revealing new findings of a significant role of powerful internal actor in shaping the organizational response to institutional pressure. Besides, it have practical implications on policy formulation by the Indonesian Accounting Association as a standard-setter body.

Published: May 2022

En el presente trabajo se estudió el efecto del dopaje de YFeO3 adicionando 0.2 % mol de Bi3+, con la intención de modificar sus propiedades magnéticas y dieléctricas a través de la modificación de sus parámetros de red o distorsión de su estructura cristalina. La síntesis de YFeO3 y de Y0.8Bi0.2FeO3 se llevó a cabo mediante molienda de alta energía durante 5 h. Los polvos obtenidos fueron compactados y tratados térmicamente a 800 °C durante 6 h. Por medio de difracción de rayos X (DRX) se corroboró la formación de YFeO3 como fase mayoritaria, con pequeñas proporciones de YIG (Y3Fe5O12, granate de hierro e itrio). Los ciclos de histéresis muestran un comportamiento antiferromagnético para la muestra sin dopaje y ferromagnético para las muestras dopadas. Las mediciones dieléctricas muestran un incremento en sus valores de permitividad relativa con respecto a la muestra sin dopar.

Published: May 2022

La determinación de la sucesión cronológica relativa de las etapas de deformación frágil en la Sierra de Pachuca, es un elemento fundamental para entender los procesos de la captación pluvial en la región y la mineralización en el distrito minero Pachuca-Real del Monte. A partir de la cartografía a semidetalle en los cerros La Sotolera y La Crucita, al oriente de Pachuca, se han identificado 4 etapas de deformación frágil que afectan a rocas de composición predominantemente félsica del Plioceno-Cuaternario. Siguiendo el orden cronológico relativo, la primera etapa de deformación frágil (F1) se caracteriza por fallas normales NW-SE, con el bloque del techo hacia el NE y se asocia con el emplazamiento de diques félsicos. La segunda etapa (F2) está constituida por fallas normales predominantemente E-W y con el bloque del techo hacia el S. La tercera etapa (F3) la constituyen fallas de trans-tensión con  desplazamiento lateral derecho y componente normal con el bloque del techo hacia el S, ocurriendo a lo largo de planos subparalelos a F1. La etapa F4 es la más reciente ya que afecta a depósitos epiclásticos y se caracteriza por fallas inversas NW-SE con el bloque del techo hacia el SW. Por lo anterior, se sustenta la hipótesis de que la deformación frágil en la región constituye un continuo pulsante y que, muy probablemente, tenga actividad en el presente.
Micro-diamantes originados por impacto de meteoritos
Authors: Mendez Escamilla Y. , Gallegos Ortega G. , Cobos-Murcia J.A.
Published: May 2022

Los micro-diamantes formados por un meteorito o también llamados diamantes de impacto,  son diamantes creados a partir del metamorfismo generado por el choque entre un cuerpo cósmico y la corteza (zona de impacto). Para que este fenómeno ocurra, deben darse ciertas condiciones termodinámicas. Hasta el momento, solo se conoce la formación de microdiamantes y se desconocen las condiciones energéticas emitidas por el choque de masas (meteorito y suelo) para asemejarse a uno de los procesos geológicos más importantes para la formación de diamantes terrestres, así como la forma en que se expresa espontáneamente dicho fenómeno. Por ello, en el presente trabajo se estudiaron simuladamente los cambios termodinámicos (entalpía, entropía y capacidad calorífica) a los que es sometido el carbono de la corteza terrestre para la formación de diamantes terrestres, pero bajo las condiciones de impacto de meteoritos. Para ello se utilizaron los softwares HSC Chemistry (versión 5.1) y wolframalpha manipulando las variables fase del carbono y temperatura, esta última de acuerdo a los valores registrados para la formación de micro-diamantes por impacto y diamantes terrestres, así mismo se estudiaron los resultados de acuerdo a la fase del carbono. Los resultados del trabajo indicaron que el fenómeno es exógeno y/o endógeno dependiendo de la fase del carbono capturado en el software y su grado de dispersión de energía. Ya que a mayor dispersión de energía la formación de diamantes no se ve favorecida.
Bolas de lava acrecionales en la formación Atotonilco el Grande, Estado de Hidalgo, México
Authors: Ortiz-Hernández L. E. , Escamilla-Casas J. C. , Cruz-Chávez E.
Published: May 2022

La Formación Atotonilco el Grande es una sucesión sedimentaria-volcánica de 500 a 600 m de espesor, de edad Plioceno, que aflora principalmente en las inmediaciones del poblado de Atotonilco el Grande, en el estado de Hidalgo, México central. La secuencia volcánica de la cima de la Formación consiste en derrames fisurales que forman mesetas, en las cuáles es común encontrar disyunción columnar en el frente de los derrames, o también algunos tubos de explosión y grandes esferoides lávicos. Estas últimas estructuras son de forma esférica o ahuevada, con exfoliación concéntrica característica, diámetro de 4 a 10 m, y están embebidas en un material tobáceo muy argilizado. Estas estructuras se interpretan como bolas de lava acrecionales. Su origen se atribuye al desprendimiento de grandes fragmentos fundidos, en el frente de avance del flujo lávico fisural, en pendientes muy pronunciadas. Dado su gran tamaño, se sugiere su proximidad al centro de emisión, en las últimas etapas del vulcanismo basáltico.

Published: May 2022

Debido a la presencia del ión NH4+ en diversas fuentes de agua dulce en concentraciones relativamente bajas (< 5 mg/L), a la dificultad de su separación y a la búsqueda de alternativas de bajo costo que permitan su recuperación o eliminación, en el presente trabajo de investigación se realizó la evaluación cinética de la sorción de NH4+ en una toba zeolitizada, empleando soluciones acuosas ideales de NH4Cl a concentraciones 0.005 N, 0.015 N y 0.020 N con valores de pH de 5.67, 5.46 y 5.43, respectivamente, en condiciones estáticas, utilizando sistemas independientes a temperaturas de 25 y 35 °C. Los resultados experimentales indican que la sorción de NH4+ es limitada y obedece la ley de acción de masas, siendo el principal mecanismo de sorción el intercambio iónico, donde los iones desplazados de la toba zeolitizada corresponden a Na+, K+ y Ca2+. Los datos de concentración de NH4+ respecto del tiempo de reacción para las diferentes condiciones de trabajo fueron analizados bajo el modelo cinético de pseudo segundo orden, determinando las constantes de velocidad y las correspondientes energías de activación para cada caso.

En el presente trabajo se realizó un estudio electroquímico para analizar el proceso de electrodepositación de cobre sobre ultramicroelectrodos (UMEs) de Pt de diferentes diámetros (10, 15 y 25 μm); a partir de una solución acuosa de CuSO4 1 mM y (NH4)2SO4 0.1 M como electrolito soporte. A partir del estudio voltamperométrico se encontró que el proceso de reducción comienza en -0.4 V mientras que el de oxidación en 0.5 V. Para determinar el mecanismo de nucleación y crecimiento de los electrodepósitos de cobre, se realizó un análisis cinético a partir de los transitorios obtenidos a partir del estudio cronoamperométrico. Mediante ajustes no lineales del modelo matemático propuesto por Barin et al., aplicado a los transitorios potenciostáticos experimentales, se encontró que el proceso se encuentra controlado por la difusión.

En el presente trabajo se analiza la actividad electrocatalítica, hacia la oxidación de borohidruro de sodio (NaBH4), por medio de materiales a base de Cu, Co y Cu-Co previamente electrodepositados sobre un sustrato de carbón vítreo (CV). Tanto la síntesis como la evaluación catalítica se llevaron a cabo mediante técnicas electroquímicas y la capacidad oxidativa de las partículas de Cu, Co y Cu-Co fue examinada mediante voltamperometría lineal. Los resultados indican que la modificación del electrodo de trabajo con las estructuras metálicas a base de Cu, Co y Cu-Co tiene un efecto favorable hacía la oxidación de BH4-. Por otro lado, oxidar los electrodepósitos obtenidos, previo a la oxidación del ión borohidruro, mejora apreciablemente sus propiedades electrocatalíticas lo que se refleja en el registro de un incremento apreciable en la corriente de oxidación en comparación con el caso donde los electrodepósitos no fueron previamente oxidados.

Se evaluó la liberación de clorhidrato de metformina (HM) a través de una matriz de arabinoxilanos extraídos de bagazo de cebada (BSG-AX). Para ello, se prepararon dispersiones de BSG-AX y HM, con diferentes contenidos de Ca2+, las cuales se liofilizaron y se prensaron, con la finalidad de obtener sus correspondientes tabletas, que se sometieron a una cinética de liberación de HM. La concentración de HM liberada al medio acuoso se determinó a través de medidas de absorbancia, a una longitud de onda (l= 236 nm, máximo de de absorción de HM), cada 30 min. De acuerdo con los resultados obtenidos, el tiempo de liberación de HM aumentó en función del incremento de la concentración de Ca2+, teniendo una liberación de hasta el 90% (en 6.5 h) para la tableta sin Ca2+; mientras que, para la mayor concentración de Ca2+ (0.3 mol L-1) se obtuvo 75% de liberación en 11.5 h. Los resultados sugieren que los BSG-AX constituyen un material adecuado para la producción de vehículos de liberación de fármacos, como el HM.

Bioestratigrafía preliminar del afloramiento “La Trinidad” Puebla (sinemuriano, jurásico- inferior) de la formación Huayacocotla
Authors: Hernando Pancardo C. Y. , Esquivel Macias C.
Published: May 2022

El afloramiento “La Trinidad” estudiado por Contreras y nuñez (1984), con base en amonitas es correlacionado con 18 afloramientos ya documentados. La zonación estándar del Jurásico Inferior utilizada durante 60 años para interpretar la bioestratigrafía de México, revela que la Formación Huayacocotla no corresponde. En la presente investigación se busca explicarlo considerando la paleobiogeografía diferencial entre la paleo-provincia tetisiana occidental y el Océano Pacífico del Jurásico Inferior. Se realizó un perfíl de 300 metros, de los cuales 60 son estratos representativos con los amonitas Paltechioceras harbledownense; P. rothpletzi; P. mexicanum; P. tardecrecens; P. burckhardti; Orthechioceras obliquecostatum; O. incaguasiense; O. pauper; Gleviceras palomense; Oxynoticeras sp.; O. victoris; Euechioceras viejense; Eparietites cf. chofatti; Eparietites; Arnioceras geometricoides; A. salasi; A. monjezlopezi; Geyeria serorugata; Euerbenites bravoi; Plesechioceras sp. y Euagazziceras. subsauceanum. Las especies de: Paltechioceras, Ortechioceras, Oxynoticeras, Echioceras, indican las zonas Oxynotum y Raricostatum que correlacionan con la localidad tipo de la Formación Huayacocotla; No obstante, la simultánidad de: Vermiceras, Arnioceras, Coroniceras, Metophioceras, Vermiceras y Microderoceras del Sinemuriano Inferior obliga a replantear la validéz de dicha zonación. La explicación tendría que ampliar el rango de especies índice como Paltechioceras rothpletzi (el mejor índice de la zonación europea), pero parece más adecuado postular que la Formación Huayacocotla actuó como barrera variable durante el Sinemuriano entre Europa y el Océano Pacífico, lo que incrementó la diversidad (27 especies solo en el presente afloramiento) y notable endemismo (15 endémicas y 12 compartidas con Europa o Norteamérica), que se interpreta como un caso de corredor de intercambio faunístico.

Published: May 2022

This study examines teenagers and karaoke nights. The purpose of this study was to determine the cause of teenagers going to karaoke nights and the impact of frequent karaoke nights. We used qualitative analysis. The study shows that there are various reasons why teenagers come to karaoke nights. Some of them come from broken home families so the teenager looks for another place outside the home for disappointment. Some teenagers go to karaoke places to look for additional income. They can work as waiters or become singers who are booked by officials or businessmen who have a lot of money. There are even teenagers who become called women to serve them. Another reason why teenagers go to karaoke is the lack of parental supervision. The impact of teenagers frequenting karaoke nights is the unhealthy association that tends to lead to promiscuity which is very detrimental to themselves and their parents. Promiscuity becomes accustomed to being carried out by teenagers so that it damages their brains and minds. The most visible impact when teenagers are familiar with the world of karaoke nights is the quality of their education is damaged, their enthusiasm for learning decreases, and they are lazy to go to school.ABSTRAKPenelitian ini mengkaji tentang remaja dan karaoke malam.

Ada diantara mereka berasal dari keluarga broken home sehingga remaja tersebut mencari tempat lain di luar rumah untuk berbagi dengan teman-temannya yang juga menyukai tempat karaoke sebagai pelampiasan rasa kecewa. Ada juga  remaja ke tempat karaoke yang bertujuan mencari penghasilan tambahan. Mereka bisa bekerja sebagai pelayan atau menjadi penyanyi yang dibooking oleh pejabat atau pengusaha yang banyak uang. Bahkan ada remaja yang menjadi wanita penggilan untuk melayani mereka. Penyebab lain remaja ke tempat karaoke karena kurangnya pengawasan orang tua. Dampak yang ditimbulkan dari seringnya remaja ke tempat karaoke malam yaitu pergaulan yang tidak sehat yang cenderung mengarah ke pergaulan bebas yang sangat merugikan diri sendiri dan orang tua. Pergaulan bebas menjadi terbiasa dilakoni oleh remaja sehingga merusak otak dan pikirannya. Dampak yang paling terlihat ketika remaja sudah mengenal dunia karaoke malam adalah kualitas pendidikannya rusak, semangat untuk belajar turun, dan bermalas-malasan untuk sekolah.

Published: May 2022

With the development of information technology that is so fast today, inevitably all aspects of life, including educational institutions, must follow. The university has also started implementing new student admissions through online media, from the registration process, payments, entrance tests and announcements of being accepted or rejected. In its implementation, find obstacles, how is the payment system? if you use a transfer, it's hard to tell which one pays the registration fee and the others. After discussing with the leadership, marketing team and the bank, it was decided to use the virtual account (VA) method.

The author then analyzes and designs an online new student admission payment information system using the virtual account (VA) method. The case study adopted in this study at the Merdeka University, Surabaya. Previously, new student admissions were carried out directly on campus, but in the current pandemic season, it is not possible for prospective students to come to campus considering the danger of covid is still very dangerous. Therefore, it is very appropriate if at this time Merdeka University Surabaya had to change the system from prospective students registering to come to campus using online media.

The method that the author uses in making this application with the waterfall, starting from the study of literature, analysis, design and implementation of the program. For registration and entrance test, the author uses web media and for payment processing the author uses the virtual account (VA) method.

This study aims to examine the concept of communication according to al-Jahidz. Communication comes from Latin communication, which is rooted in the word communism, which means the same meaning of something. In other words, a communication event will take place if the people involved in it have the same perception or meaning of what is being communicated. As a term, communication can be defined as the delivery and reception of messages or information between two or more people using verbal (language) and nonverbal symbols. This article uses a descriptive qualitative method, which describes and analyzes in-depth verbal communication according to Al-Jahidz. The data collection technique makes use of primary data sources through documents of al-Jahidz books (al-Bayan wa al-Tabyin, al-Hayawan, al-Risalah Li al-Jahidz, al-Hayawan) and other books that discuss al-Jahidz (Usmaniyah Li al-Jahidz, al-Bukhala’ Li al-Jahidz, al-Malamich al-Adaiyah Li al-Jahidz). The results reveal that Al-Jahidz is an Arabic linguist who discusses the theory of verbal communication which includes: the concept of verbal communication, forms of verbal communication and its characteristics, the effect of verbal communication on the same speaker alongside its relationship to the intellectual level, the influence of physical signs or movements on strengthening and controlling verbal performance, commissions, and their effects on verbal performance, varying performance effects on verbal communication, and preference for speaking over silence.

The Ministry of Education and Culture has initiated a new university program, namely Merdeka Belajar Kampus Merdeka (MBKM) to prepare superior and competitive human resources in the 4.0 revolution era. The research method employs field research, which includes qualitative research. Research data collected from primary data and secondary data sources and the data collection techniques using documentation, observation and interviews. This research uses the process of data reduction, data presentation, and conclusions to analyze the data. The finding shows that: 1) the implementation of MBKM at the Jambi university is still not going well because it still finds confusion in the process, so it is necessary needs adaptations related to the curriculum and facilities, 2) the supporting factors are the willingness and enthusiasm of the educators and students as seen from their cohesiveness in preparing for the establishment of MBKM, while 3) the inhibiting factor is the need to get a lot of MoU from various institutions. In addition, there are other challenges, namely the readiness and skills of students to teach and guide in schools. This means that students must be part of strengthening learning and numeracy.

Palm oil is a dormant plant. The main cause of oil palm seed dormancy is the hard and thick seed coat or shell, inhibiting the effective absorption of water and gases. The presence of a seed coat barrier causes the germination process of oil palm seeds to be hampered. This study aims to determine the effect of chemical treatment on breaking palm oil dormancy by immersion in a solution of strong acids, namely H2SO4, KNO3, and HCl. This study used a completely random design (CRD) with three treatments, four observations, and five replications. The results of the following study were analyzed using MANOVA with the parameters observed were germination rate, germination rate, seedling height, and most extended root length. Based on the analysis results, it was found that immersion with a solution of a strong acid, namely H2SO4, KNO3, and HCl, had different effects on breaking palm oil dormancy. The highest average germination rate was through immersion with HCl, which produced an average of 65.24. The highest average germination was through immersion in H2SO4 with an average of 8.52. In contrast, the average seedling height and most extended root length were soaked in HCl with an average of 35.28, and 15, respectively. Based on the results obtained, the best chemical treatment for breaking palm oil dormancy is through soaking with HCl.

Published: May 2022

Strateji, insanlığın varoluşundan bu yana farklı bağlamlardaki yönetim anlayışları içerisinde oluşmuş bir kavramdır. Kavramın temeli insanın toplu olarak yaşamasıyla birlikte ortaya çıkan yönetim ve liderlik kavramlarıyla birlikte olgunlaşmasına rağmen kendi başına bir anlam ifade edecek şekilde kullanımı daha ileriki zamanlarda mümkün olmuştur. Strateji olgusunun eski çağlarda savaş sanatının bir parçası olarak ön plana çıkan kavramsal özü, sanayi devriminin ve ardından gelen bilgi çağının etkisiyle farklı boyutlar kazanmıştır. Savaş sanatının bir temsili olarak yönetim yazınına giren strateji kavramsallaştırması günümüz örgütlerinde; stratejik yönetim, stratejik bilgi sistemleri, stratejik performans yönetim sistemleri, stratejik öğrenme, stratejik maliyet yönetimi, girişimcilik stratejileri, stratejik insan kaynakları yönetimi, stratejik liderlik ve davranışsal strateji gibi birçok farklı alanda kullanılmaya başlanmıştır. Bu bağlamda, çalışmada stratejik yönetimin günümüz örgütsel yapıları için önem arzeden bu yeni yönelim ve kullanım alanlarına değinilerek bir çerçeve çizilmeye çalışılmıştır. Çizilen bu çerçeve ile stratejik anlayışın örgütsel alandaki izdüşümlerine dair özet bir değerlendirme yapılarak kavramsal bir tartışma ortaya konmaya çalışılmıştır.
El conocimiento local sobre el teñido de la lana en una comunidad mazahua del Estado de México
Authors: Franco Maass Sergio , Cruz Balderas Yolanda
Published: May 2022

El teñido de la lana forma parte del patrimonio cultural de la etnia mazahua. En la comunidad de Santa Rosa de Lima el conocimiento local sobre sus técnicas se ha venido perdiendo debido a diversos factores sociales y económicos. Se realizó un levantamiento etnográfico con el que se hizo el análisis comparativo de los procesos de teñido entre 1995 y 2017, el cual destaca entre sus principales hallazgos que si bien las técnicas han variado y existen deficiencias en los procesos, las mujeres de la localidad mantienen su tradición y logran obtener los colores requeridos para su indumentaria. Éstos, y los materiales tintóreos de los que provienen, se encuentran estrechamente relacionados con la identidad cultural de las mujeres mazahuas. ___ The dyeing of wool is part of the cultural heritage of the Mazahua people. In the community of Santa Rosa de Lima, local knowledge of their techniques has been lost due to various social and economic factors. An ethnographic survey was conducted to make a comparative analysis of the dyeing processes between 1995 and 2017. This survey highlights, among its main findings, that although the techniques have varied and there are deficiencies in the processes, the local women maintain their tradition and manage to obtain the colors required for their clothing. These colors, and the dyeing materials from which they come (mainly indigo and cochineal), are closely related to Mazahua women’s cultural identity.
On correctness of conditions for the CSIDH algorithm implementation on Edwards curves
Authors: Bessalov A.V.
Published: May 2022

Incorrect formulation and incorrect solution of the problem of the CSIDH algorithm implementation on Edwards curves  was revealed in one of the famous works. The purpose of this paper is to present a detailed critique of such concept with a proof of its inconsistency. Specific properties of three non-isomorphic classes of super singular curves in the generalized Edwards form are considered: full, quadratic, and twisted Edwards curves. Conditions for existence of curves of all 3 classes with  order of curves over a prime field  are determined. The implementation of the CSIDH algorithm on isogenies of odd prime degrees is based on the use of quadratic twist pairs of elliptic curves. To this end, the CSIDH algorithm can be built both on complete Edwards curves with quadratic twist within this class, and on quadratic and twisted Edwards curves forming pairs of quadratic twist. In contrast to this, the authors of a well-known work are trying to prove theorems that state that there is a solution within one class of  curves with a parameter which is a square. The critical analysis of theorems, lemmas, erroneous statements in this work is carried out. Theorem 2 on quadratic twist in classes of Edwards curves is proved. The CSIDH algorithm modification based on isogenies of quadratic and twisted Edwards curves is presented. To illustrate the correct solution of the problem, an example of Alice and Bob calculations in the secret sharing scheme according to the CSIDH algorithm is considered for.
