פודגוגיה: משמעותם הפדגוגית של הסכתים
Authors: מלניק דביר
Published: October 2021

אחד האופנים שבהם השפיעה המהפכה הדיגיטלית על תקשורת ההמונים הוא תופעת ההסכתים (פודקאסטים), והיא הולכת ותופסת תאוצה בשנים האחרונות. לשימוש הדיגיטלי של ההסכת מספר יתרונות בולטים. המרכזי שבהם הוא הנגישות. יתרון נוסף הוא מאפייני הזמישות (agility, הלחם של זריזות וגמישות), שאותה ניתן לחלק לגמישות בשימוש – האפשרות להאזין להסכת בכל זמן ומקום לפי הצורך, ולזריזות השמיעה – היכולת לעצור (לשהייה מחשבתית), לחזור לאחור (שמיעה חוזרת) ולהתאים את מהירות הדיבור (מאיטי ועד מהיר פי שניים מקצב הדיבור המקורי). בכך מתגברת הטכנולוגיה על מגבלות של זמן, של מרחב (טווח קליטה) והבהירות של הרדיו המסורתי. מתוך החדשנות הטכנולוגית והתקשורתית עולה וצומחת גם החשיבות הפדגוגית של ההסכתים. ההסכת, מתברר, כולל מספר אופנים שבהם ניתן להשתמש כאמצעי לימודי ועליהם מרחיב הערך.
Graft Selection in Contemporary Anterior Cruciate Ligament Reconstruction
Authors: Buerba Rafael A. , Boden Stephanie A. , Lesniak Bryson
Published: October 2021

In the last decade, there have been significant advances in our understanding of anterior cruciate ligament (ACL) reconstruction. Recent prospective cohort studies have identified risk factors for ACL reconstruction graft failure such as younger patient age, increased activity level, nonanatomic tunnel placement, and the use of allograft. Among these, the most easily modifiable risk factor is graft choice. Given that the surgeon's recommendation has been shown to be one of the most important factors behind patients' graft choice, it is critical that the operating surgeon have a thorough understanding of all the ACL graft options available to choose the graft that would be most suitable for the patient's personalized reconstruction (i.e., patient's anatomy, sport, level of competition, age, risk factors for failure, and graft used in previous ACL surgery). The purpose of this review is to provide an up-to-date understanding of the current ACL graft reconstruction options. The indications, advantages, and disadvantages of the different ACL reconstruction graft options available will be discussed.

Published: October 2021

The development of technology and information, especially in the field of information communication, is very rapidly developing, one of them is the communication media of smart phones. one of the facilities provided by smart phones is the exchange of information in the form of sending text messages through Short Message Service (SMS). This information can be in the form of important data that not all parties can find out. Some risks that can threaten message security in SMS services include SMS Spoofing, Snooping SMS and SMS Interception.

The message security system in the form of text is one of them with a cryptographic system. Cryptography is a message security science that aims to maintain the confidentiality of information contained in data so that information cannot be known by irresponsible parties. Cryptography changes the meaningful writing to be meaningless by using various kinds of cryptographic algorithms. The algorithms used are ElGamal and Vigenere Chiper. The ElGamal algorithm uses 2 different keys in encrypting and decrypting the public key for encryption and the private key for decryption. While Vigenere chipers only use one key that is the same for encryption and description.

With the text message encoding application using the ElGamal and Vigenere Chiper algorithms, it is expected to help smart phone users with the operating system.

Mengimplementasikan Dwi Kewarganegaraan Kristen dalam Era Pos-Sekulerisme
Authors: Pramonojati Gilrandi A.
Published: October 2021

This article examines the relationship of the Church to politics in post-secularism popularized by Jurgen Habermas. The research method used in this research is literature study. This research finds that, Post-secularism offered by Habermas provides space for the Church to translate the wealth contained in religion into a public message. In the view of post-secularism the Church has an important role to fill in the empty spaces that cannot be achieved by rationality. Habermas's thoughts on post-secularism also serve as a bridge to harmonize faith and rationality, as well as to explain dual citizenship as an unrelated Christian political view.Artikel ini menelaah hubungan Gereja dengan politik dalam pos-sekulerisme yang dipopulerkan oleh Jurgen Habermas. Metode penelitian yang digunakan dalam penelitian ini adalah studi pustaka. Penelitian ini menemukan bahwa, Pos-sekulerisme yang ditawarkan oleh Habermas memberi ruang Gereja untuk menerjemahkan kekayaan yang terkandung dalam agama menjadi pesan publik. Dalam pandangan pos-sekulerisme Gereja mempunyai peran penting untuk mengisi ruang kosong yang tidak dapat dijangkau oleh rasionalitas. Pemikiran Habermas mengenai pos-sekulerisme juga menjadi jembatan untuk menyelaraskan iman dan rasional, sekaligus menerangkan kewarganegaraan ganda sebagai pandangan politik Kristen yang selama ini tidka dimengerti.
Vista Siklus Apostasi dan Kuasa Doa dalam Kitab Hakim-hakim untuk Intensi Relevansional
Authors: Zega Fati Aro
Published: October 2021

Abstrak: Gambaran kebejadan dan apostasi manusia itu terlihat dengan jelas di dalam Kitab Hakim-hakim. Kitab ini menjadi catatan sejarah dan metafora tentang tendensi di setiap zaman dan setiap generasi terhadap fenomena apostasi. Apostasi terjadi bukan karena tidak mengakui adanya Tuhan tetapi memercayai sesuatu selain Tuhan. Ternyata satu-satunya yang dipelajari dari sejarah adalah tidak mempelajari sejarah. Mengunakan metode kualitatif deskriptif dengan pendekatan studi literatur didapatkan kesimpulan bahwa dosa kemurtadan membuat semua prestasi manusia sia-sia. Semua hasil kerja keras tidak dapat dinikmati. Dosa merampas apa pun yang diperoleh. Bahkan akan mendatangkan bencana kemanusiaan, sampai mereka bertobat. Tetapi, jika mereka sungguh-sungguh bertobat, mencari Tuhan, dan berdoa memohon belas kasihan-Nya, maka sesuai dengan wahyu di Kitab Hakim-hakim, Tuhan akan mendatangkan kelegaan, kesembuhan. Hakim yang definitf, Yesus Krustus, akan turun tangan mengatasi apa pun yang tidak bisa dilakukan manusia. Prinsip penting yang muncul dalam Kitab Hakim-hakim sebagai sebuah kebenaran alkitabiah, “dosa apostasi mengasilkan sengsara, doa dan pertobatan melahirkan kesejahteraan. Allah di tambah ketaatan akan mengasilkan kuasa, kasih karunia Tuhan lebih besar dari segala dosa.

Abstract: The description of human depravity and apostasy can be seen clearly in the Book of Judges. This book is a historical record and a metaphor for the tendency in every age and every generation to the phenomenon of apostasy. Apostasy occurs not because of not acknowledging the existence of God but believing in something other than God. It turns out that the only thing to learn from history is not to study history. Using a descriptive qualitative method with a literature study approach, it is concluded that the sin of apostasy makes all human achievements in vain. All the results of hard work cannot be enjoyed. Sin takes whatever is gained. It will even bring disaster to humanity, until they repent. However, if they truly repent, seek God, and pray for His mercy, then according to the revelation in the Book of Judges, God will bring relief, healing. The definitive Judge, Jesus Christ, will intervene in anything that humans cannot do. An important principle that appears in the Book of Judges as a biblical truth, “the sin of apostasy produces suffering, prayer and repentance beget prosperity. God plus obedience will produce power, God's grace is greater than all sin.

Published: October 2021

Abstrak
Apa yang menyebabkan orang-orang Pentakosta melakukan hal-hal yang mereka lakukan? Apa yang memotivasi mereka? Mengapa mereka melayani dengan cara yang mereka lakukan? Ini semua adalah pertanyaan bagus yang pantas mendapatkan jawaban. Untungnya, Alkitab memberi kita beberapa wawasan tentang hal-hal ini. Salah satu faktor kunci yang mempengaruhi praktik Pentakosta adalah pola pikir Pentakosta. Artikel ini akan berfokus terutama pada satu bagian Alkitab yang akan membantu pembaca dalam memahami pikiran Pentakosta. Kita akan melihat pengalaman orang Kristen abad pertama di kota Yerusalem dalam Kisah Para Rasul 4:23-31.

Abstract
What causes Pentecostals to do the things they do? What motivates them? Why do they minister in the ways that they do? These are all good questions that deserve answers. Fortunately, the Bible supplies us with some insight into these matters. One of the key factors that impacts Pentecostal practice is the Pentecostal mindset. This article will focus primarily on one biblical passage that will help the reader in understanding the Pentecostal mind. We will be looking at the experience of the first-century Christians in the city of Jerusalem in Acts 4:23-31.

Published: October 2021

Land registration aims to guarantee legal certainty and certainty of land rights. By holding land registration, the parties concerned can easily find out the status of the legal status of the particular land they are dealing with, their location, area and boundaries. And also as a condition for the implementation of orderly land administration. The purpose of this study is to find out the legal arrangements regarding the process of registering land rights and ownership status in order to confirm legal certainty and how to implement, constraint factors and solutions to problems that occur in the community. This research uses normative legal research methods. The normative method is writing that uses primary materials or data. In normative legal research, library materials in the form of basic data which in the study are classified as secondary data. Secondary data can include primary legal materials, secondary legal materials and tertiary legal materials. The results of the study indicate that the legal arrangements regarding the responsibilities of the Batam City National Land Agency in the process of registering land rights have been carried out well by the Batam City National Land Agency in order to realize legal certainty for the people of Batam City. However, in carrying out their duties there are still obstacles in the process of registering land rights in Batam City because of the imbalance of authority with the Batam Concession Agency as the holder of land management rights in Batam City. So, the solution is expected to have special regulations regarding this so that the process of registering land rights in Batam City can run in accordance with the laws and regulations.

Convolution and Recurrent Hybrid Neural Network for Hevea Yield Prediction
Authors: Varghese Lince Rachel , Kandasamy Vanitha
Published: October 2021

Deep learning techniques have been used effectively for rubber crop yield prediction. A hybrid of Convolutional Neural Network (CNN) and Recurrent Neural Network (RNN) is the best technique for crop yield prediction because it can effectively handle uncertainty of features. Hence, in this paper, a hybrid CNN-RNN method is proposed to forecast Hevea yields based on environmental data in Kerala state, India. The proposed hybrid CNN-RNN method reduces the internal covariate shift of CNN by batch normalization and solves the gradient vanishing or exploding problem of RNN using LSTM with a cell activation mechanism. The proposed method has three essential characteristics: (i) it captures the time dependency of environmental factors and improves the inherent computational time; (ii) it is capable of generalizing the yield prediction under uncertain conditions without loss of prediction accuracy; (iii) combined with the back propagation and feed forward  method it can reveal the extent to which samples of weather conditions and soil data conditions are suitable to provide a clear boundary between rubber yield variations.

Using Instrumentation to Reproduce the Execution of Java Concurrent Programs
Authors: Delamaro Márcio Eduardo
Published: October 2021

The Java language provides mechanisms to implement concurrency and synchronization based on the monitor model. Testing multi-thread Java programs many times requires to re-execute them with determined test data. The problem is that re-executing such programs with a same test datum does not guarantee the same behavior due to the non deterministic scheduling policy implemented in the JVM. In this paper we present a simple way to reproduce the behavior of a multi-thread Java program, based on program instrumentation.

Authors: Pinheiro Wallace A. , Xexéo Geraldo , Souza Jano M. de , Barros Ricardo
Published: October 2021

O cenário da explosão de dados já era previsto desde 1970 por Alvin Toffler em "Future Shock". A sobrecarga de informação considera um espaço informacional poluído, isto é, contém muita informação de baixa qualidade ou baixa relevância quanto à tarefa que nos propomos. Se a situação atual já nos parece crítica, o aumento crescente e sem controle da quantidade de informação projeta que os problemas desse tipo aumentarão já em curto prazo. Para auxiliar no tratamento desses problemas, este trabalho propõe um framework de modelagem de processos baseados em redes de Petri de alto-nível e regras ativas. Os processos aqui modelados na forma de padrões exemplificam o uso desse framework e são voltados para a eliminação de dados não relevantes e desnecessários. Os padrões propostosintegram as perspectivas de fluxos de controle e de dados em um modelo único de descrição.

Dispositivos móveis tais como smartphones e tablets PC têm se tornado uma importante plataforma de comunicação e acesso à informação. Isto implica no surgimento de novas formas de interação com estas tecnologias, que incluem a utilização de dispositivos móveis como recurso no apoio à tomada de decisão. Considerar o contexto do usuário enquanto o mesmo busca informações deve maximizar seu grau de satisfação junto ao sistema, uma vez que a informação espaço/tempo pode proporcionar maiores detalhes nos processos de filtragem de informação. Nesta perspectiva, é apresentado um sistema de recomendação capaz de personalizar ofertas de produtos e serviços com base na localização geográfica, bem como nas estimativas de padrões de consumo dos usuários móveis

Published: October 2021

Este trabalho descreve questões atuais de pesquisa sobre a implementação de uma plataforma, chamada OpenMuseum, para colaboração e compartilhamento de conhecimento entre instituições de patrimônio cultural. A maior parte do trabalho desenvolvido para este domínio é orientado para o uso de modelos globais de integração. De forma construtiva, o OpenMuseum foi projetado usando uma abordagem fracamente acoplada, na qual as instituições colaboram através de uma plataforma leve de interoperabilidade, chamada JamSession, que lida efetivamente com a heterogeneidade dos sistemas orientados a serviços. Para gerenciar a natureza complexa da informação do patrimônio cultural, algumas extensões do JamSession devem ser implementadas. A plataforma estendida servirá para sistemas interativos cooperativos em geral.

Context-aware recommendation systems use contextual data to recommend a fully personalized suggestion to their users, for instance, using the massive workloads produced by the usage of mobile apps. In this paper, we collected and analyzed a dataset from social media related to the Belo Horizonte’s 2020 Carnival to understand how this event attracts tourists (or Belo Horizonte’s non-resident), analyzing their interactions with a large recommendation system. We built a point-of-view of an event mixing its features in two social networks: Twitter and Google Review. Our results show that combining traits lead to better information about the given context using social networks. It helps both the tourists choosing where to travel and the local establishments to provide better services.
Comparing International Movements of Tourists: Official Census versus Social Media
Authors: Skora Lucas Eduardo Bonancio , Silva Thiago Henrique
Published: October 2021

Tourism is one of the most competitive, lucrative, and socially important economic segments in the world. Therefore, understanding the behavior of tourists is strategic for improving services and results. Many studies in the literature explore this issue using traditional data, such as surveys. These approaches provide reliable, precise information, but it is hard to obtain on a large scale, making studying worldwide patterns difficult. Location-Based Social Networks (LBSNs) could minimize these problems due to the ease of acquiring large amounts of detailed behavioral data. Nevertheless, before using such data, it is imperative to determine whether the information reveals behaviors comparable to traditional data - our ground truth. Thus, this work investigates whether the international flow of tourists measured with LBSN data is similar to the behavior estimated by the World Tourism Organization with traditional data sources. Our results suggest that LBSNs data represent the studied behavior well, indicating that they could be used in research regarding tourism mobility at different levels.

Published: October 2021

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) is severely affecting the worldwide population. It belongs to the coronavirus family which exhibit protein constituted enveloped single-stranded RNA. These viral proteins undergo post-translational modifications (PTMs) that reorganized covalent bonds and modify the polypeptides and in turn modulate the protein functions. Being viral machinery, it uses host cells system to replicate itself and make their copes, their proteins are also subject to PTMs. Glycosylation, palmitoylation of the spike and envelope proteins, phosphorylation, of the nucleocapsid protein are among the major PTMs responsible for the pathogenesis of the viral infection phase. The current knowledge of CoV proteins PTMs is limited and need to be exploring for to understand the viral pathogenesis mechanism and PTMs effect of infection phase.
The urban impacts of climate change: introduction
Authors: Goldhill Simon , Fitzgibbon Georgie
Published: October 2021

Climate change is a global phenomenon that significantly impacts urban life. Rising global temperature causes sea levels to rise, increases the number of extreme weather events such as floods, droughts, and storms, and increases the spread of tropical diseases. All these have costly impacts on cities� basic services, infrastructure, housing, human livelihoods, and health. At the same time, cities are a key contributor to climate change, as urban activities are major sources of greenhouse gas emissions. This special edition explores a range of climate change impacts in urban areas, the possibilities of adaptation and mitigation in different contexts, and the development of public participation and climate action.
The impact of the reforms of the 2000s and the Arab Spring of 2011 on the performance of the Egyptian banking sector
Authors:   Cracow University of Economics, Ahmed Ahmed L. M.
Published: October 2021

This paper aims to assess the current condition of the Egyptian banking sector, based on the past reforms of the 2000s. This analysis is based on data from the Central Bank of Egypt (CBE), data from the Egyptian banking sector and the literature review. The main fi nding is that despite many changes in the political and economic scene that drove the country into a crisis, the Egyptian banking sector was able to work well in the post-2008 period, achieving high growth rates. This study contributes to the academic literature on factors infl uencing fi nancial development in emerging counties, based on the analysis of the Egyptian banking.
Electron cryo-tomography reveals the subcellular architecture of growing axons in human brain organoids

During brain development, axons must extend over great distances in a relatively short amount of time. How the subcellular architecture of the growing axon sustains the requirements for such rapid build-up of cellular constituents has remained elusive. Human axons have been particularly poorly accessible to imaging at high resolution in a near-native context. Here, we present a method that combines cryo-correlative light microscopy and electron tomography with human cerebral organoid technology to visualize growing axon tracts. Our data reveal a wealth of structural details on the arrangement of macromolecules, cytoskeletal components, and organelles in elongating axon shafts. In particular, the intricate shape of the endoplasmic reticulum is consistent with its role in fulfilling the high demand for lipid biosynthesis to support growth. Furthermore, the scarcity of ribosomes within the growing shaft suggests limited translational competence during expansion of this compartment. These findings establish our approach as a powerful resource for investigating the ultrastructure of defined neuronal compartments.
Further enhancing the in situ visualization of performance data in parallel CFD applications
Authors: Alves Rigel F. C. , Knüpfer Andreas
Published: October 2021

This paper continues the work initiated by the authors on the feasibility of using ParaView as visualization software for the analysis of parallel Computational Fluid Dynamics (CFD) codes’ performance. Current performance tools have limited capacity of displaying their data on top of three-dimensional, framed (i.e., time-stepped) representations of the cluster’s topology. In our first paper, a plugin for the open-source performance tool Score-P was introduced, which intercepts an arbitrary number of manually selected code regions (mostly functions) and send their respective measurements–amount of executions and cumulative time spent–to ParaView (through its in situ library, Catalyst), as if they were any other flow-related variable. Our second paper added to such plugin the capacity to (also) map communication data (messages exchanged between MPI ranks) to the simulation’s geometry. So far the tool was limited to codes which already have the in situ adapter; but in this paper, we will take the performance data and display it–also in codes without in situ–on a three-dimensional representation of the hardware resources being used by the simulation. Testing is done with the Multi-Grid and Block Tri-diagonal NPBs, as well as Rolls-Royce’s CFD code, Hydra. The benefits and overhead of the plugin's new functionalities are discussed.
