The rapid development of information technology has expanded the capabilities of cyberthreads regarding computer systems. Cybercriminals are developing new ways to avoid attack detection, so existing approaches are not able to withstand the growing threat of attacks. Meanwhile, the consequences of cyberattacks are becoming more dangerous and destructive. One of the approaches to solve the problem is the construction of resilient systems that are able to quickly recover and continue to function under attack conditions. The subject of research is the construction process of the resilient computer systems in the face of cyber threats. The goal is to develop a taxonomy and ontology of resilient computer systems under cyberthreats. Results. The article presents the definitions of the resilience from the point of view of cybersecurity, presents the gap between the concepts of resilience and dependability. The paper presents the main elements of the taxonomic scheme of computer system resilience, which include threats (changes in the environment and requirements, network attacks, attacks on software, software and hardware vulnerabilities, errors, failures), information and technical conditions that computer system passes during its operating cycle, the principles on which resilience is based (proactivity, adaptability, resistance, diversity, elasticity, controlled degradation, defense in depth, ability to evolvability), as well as primary and secondary properties. Based on the above elements, a generalized taxonomic scheme of resilience related to information security has been developed. The work presents the operational cycle of a resilient CS as a set of information and technical states that the system goes through (preparation, system protection, threat detection, threat absorption, response to a threat, system recovery after a cyberattack, adaptation.) An ontology scheme of the resilience from the point of view of information security of computer systems in the presence of cyberthreats is developed. Conclusions A taxonomy and ontology of resilient computer systems in the presence of cyberthreats has been developed.
Efficacy and safety of maxillary sinus lifting with various types of grafting with implants insertion purposes: A review of the literature
Authors: Júnior João de Paula Martins , Atallah Álvaro Nagib
Published: March 2020

Context: Edentulous patients under the use of removable prosthesis face important restrictions, including sociocultural ones and, for this reason, the insertion of implants has become frequent in clinical dental practice. However, the success of the method will depend on the sort of different types of bone grafting, quality of donor area and the residual amount of bone left in insertion site. Purpose: the purpose of this study was to evaluate the effectiveness and safety of different types of bone grafts used in maxillary sinus lifting surgeries for implant insertion. Methods: systematic review of randomized clinical trials or quasi-randomized. We used the guidelines of the manual of systematic reviews from Cochrane Collaboration and a sensitive search strategy in three electronic databases has been built. Results: We included six randomized clinical trials from different regions of the world with 135 participants. Bone volume was 3% higher on the grafted site with autogenic bone pure, but not a statistically significant difference DM: 3 (-8.48-14.48), the average percentage between the vital and non-vital bone showed up 0.82% higher on the grafted site with FDBA + PRP. The average percentage of vital tissue was also 15.8% higher on the side where PRP was used. Conclusion: the available evidence is insufficient to recommend a specific type of bone grafting in sinus augmentation (lift) procedures to place a dental implant. There was no statistically significant difference for bone volume, sensory loss, local inflammatory response and loss of implants, among others. For this reason, new randomized controlled trials that evaluate the effectiveness and safety of different types of bone graft for lifting of the maxillary sinus are necessary.

Resumo: Neste artigo, fizemos um recorte da pesquisa de mestrado intitulada “Letramento estatístico na educação básica: o uso de tecnologias digitais em pesquisas de opinião” para apresentarmos e discutirmos alguns aspectos do componente afetivo do letramento estatístico, na perspectiva do modelo de Gal (2002). Nossas discussões estão ambientadas na realização de um projeto educativo de pesquisa de opinião, inspirado na metodologia do programa Nossa Escola Pesquisa Sua Opinião (Nepso), em que 16 alunos do 8º ano do ensino fundamental utilizaram tecnologias digitais (TD) como Whatsapp, Facebook e Excel para investigarem sobre uma temática que os interessasse e, com isso, desenvolvessem conhecimentos estatísticos. Em nosso processo de análise, percebemos, dentre outras coisas, que, numa aprendizagem estatística, o foco não pode ser só a própria Estatística, mas um conjunto de competências e habilidades, incluídas as estatísticas, que se relacionam aos interesses, necessidades, valores e práticas sociais das pessoas envolvidas.

Atividade de inferência informal para avaliar π
Authors: Magalhães Marcos Nascimento
Published: March 2020

Resumo: Inferência é a parte da Estatística que trata de previsões, para uma população, a partir das informações de uma amostra. O assunto é discutido de maneira formal em disciplinas de Estatística de cursos superiores, pois envolve conceitos matemáticos avançados. Entretanto, fazer previsões é algo presente na vida de todos e com os estudantes da Educação Básica não é diferente. É importante que os estudantes desse nível de ensino tenham oportunidade de fazer previsões, ainda que limitadas e informais, como uma experiência inicial do uso dessa parte fundamental da Estatística. Neste artigo, aproveitamos a mística envolvendo o número π para discutir, de modo informal, aspectos da Inferência Estatística. Descrevemos uma atividade, presente no portal AtivEstat- Atividades de Estatística, que usa conceitos simples de Geometria para avaliar o valor do número irracional π.

Informal inference activity to estimate π

Abstract: Inference is the part of Statistics that deals with forecasts for a population from the information in a sample. The subject is discussed formally in higher education statistics disciplines as it involves advanced mathematical concepts. However, making predictions is something present in everyone's life and with students at theBasic Education it is not different. It is important that students, at this educational level, have the opportunity to make predictions, even if they are limited and informal, as an initial experience of using this key part of Statistics. In this article, we take advantage of the mystique involving the number π, to informally discuss aspects of Statistical Inference. We describe an activity, included in the Portal AtivEstat - Statistics Activities, that uses simple concepts of Geometry to evaluate the value of the irrational number π.

Resumo: Neste artigo, propõe-se apresentar um estudo sobre uma Engenharia Didática de Formação, cuja finalidade maior é construir um modelo didático de referência para o ensino do conceito de Probabilidade. Para tanto, derivamos de um problema docente no ensino deste saber, identificado no momento em que os professores apresentam aos seus alunos o conceito de Probabilidade priorizando somente uma interpretação: a interpretação clássica. Neste sentido, tomamos como quadro teórico a Teoria Antropológica do Didático, e de posse das praxeologias dos professores, buscamos desenvolver um modelo didático de referência para o ensino do conceito de Probabilidade, metodologicamente amparado por uma engenharia didática de formação. A construção deste modelo didático visa abordar a aleatoriedade da Probabilidade de forma a integrar nas praxeologias didáticas suas principais interpretações: a clássica e a frequentista. Pretendemos apresentar como resultado desta engenharia didática de formação, uma alternativa didática para uma melhor abordagem do conceito de Probabilidade pelos professores do nível médio.

Observations on a didatic training engineering for the teaching of probability

Abstract: In this article, it is proposed to present a study on a Didactic Engineering of Training, whose purpose is to construct a didactic model of reference for teaching the concept of Probability. For this, we derive from a teaching problem in the teaching of this knowledge, identified at the moment in which the teachers present to their students the concept of Probability giving priority to only one interpretation: the classical interpretation. In this sense, we take as theoretical framework the Anthropological Theory of Didactics, and of possession of the praxeologies of the teachers, we seek to develop a didactic model of reference for the teaching of the concept of Probability, methodologically supported by a didactic engineering of formation. The construction of this didactic model aims to approach the randomness of Probability in order to integrate the main interpretations in the teaching praxeologies: the classical and the frequentista. We intend to present as a result of this training didactic engineering, a didactic alternative for a better approach to the concept of Probability by middle level teachers.

Efek Penambahan Fly Ash Tipe C terhadap Kuat Tekan Mortar
Authors: Naibaho Armin , Rahman Aulia
Published: March 2020

Abstrak Bahan alternatif pengganti semen mulai banyak dicari karena isu lingkungan. Proses pembuatan semen konvensional terindikasi sebagai salah satu penyumbang tertinggi dalam meningkatnya kadar karbondioksida di udara. Salah satu substansi yang marak digunakan untuk bahan pengganti semen adalah fly ash karena sifatnya yang serupa dengan semen dan jumlahnya yang melimpah sebagai hasil residu pembakaran tungku batu hara di PLTU. Secara umum, fly ash sendiri dikelompokkan menjadi dua jenis yaitu tipe C dan F. Tipe C jarang digunakan karena karakternya yang mudah mengeras. Namun, pada penelitian lebih lanjut, tipe ini memiliki kelebihan dalam meningkatnya kuat tekan pada umur prematur. Penelitian ini dibuat untuk mendapatkan rasio fly ash tipe C yang tepat dengan cementitious material pada mortar. Pengetesan dilakukan hanya pada minggu pertama dan kedua untuk mengamati perkembangan kekuatan awal. Namun, tidak semua kombinasi bisa diujikan karena kekuatannya terlalu rendah. Hanya kombinasi fly ash 25% saja yang memberikan kekuatan 20 MPa pada umur 7 hari, yang mana mengungguli sampel kontrol dengan kekuatan 19,36 Mpa. Untuk selanjutnya, kekuatan sampel fly ash cenderung lebih rendah jika dibandingkan dengan sampel kontrol.

Published: March 2020

Berenuk (Crescentia cujete L.) is one of the non-food plants that can be converted into bioethanol, where the carbohydrate and simple sugar content in the pulp is quite high, namely carbohydrate 18.61%, sucrose 59.86%, fructose 25.09% and galactose 18.24%. The bioethanol produced is liquid, so when used it will be at risk of spilling and flammable, because it is volatile. The physical properties of bioethanol can be modified into gels by adding thickening agents such as carboxymethyl cellulose (CMC), so they are relatively safe when used. The aim of this study was to produce bioethanol gel from berenuk fruit (Crescentia cujete L.) and determine the characteristics of the biotenol gel, which includes: water content, ash content, and heating value. In this study, bioethanol gel was made by mixing liquid bioethanol with CMC thickener using magnetic stirrer at a temperature of 50 ̊C. From the results of this study it can be concluded that the best characteristics of bioethanol gel were obtained by adding 3 grams of CMC (6% w / v), namely 94.94% moisture content, 0.75% ash content and 2,344 cal/ gr heat value. ABSTRAK Berenuk (Crescentia cujete L.) merupakan salah satu tumbuhan non-pangan yang dapat dikonversi menjadi bioetanol, dimana kandungan karbohidrat dan gula sederhana dalam dalam dagingnya  cukup tinggi yaitu karbohidrat 18,61%, sukrosa 59,86%, fruktosa 25,09% dan galaktosa 18,24%. Bioetanol yang dihasilkan berwujud cair, sehingga pada saat digunakan akan beresiko tumpah dan mudah terbakar, karena sifatnya yang volatil. Sifat fisik bioetanol dapat dimodifikasi menjadi gel dengan penambahan bahan pengental seperti carboxymethyl cellulose (CMC), sehingga relatif aman ketika digunakan. Tujuan dari penelitian ini adalah untuk menghasilkan bioetanol gel dari buah berenuk (Crescentia cujete L.) dan mengetahui karakteristik dari biotenol gel tersebut, yang meliputi: kadar air, kadar abu, dan nilai kalor.

The aim of the study was to determine the indicators of the dynamic component of the postural balance and subjective characteristics of the functional state of the body in elderly women with postural instability. Methods. The study involved 246 healthy women aged 60-74 years living in an urban environment. The sample was divided into two groups: those who had falls (n = 95) and those without falls (n = 151). Analysis of the postural balance was carried out using the computer-based posturographic system Balance Master (USA) and included the following tests: Sit to stand, Simple walking, Tandem walk, Step/ quick turn and Step up/over. The assessment of the quality of life, situational and personal anxiety, subjectively experienced age (SEA) and the rate of aging were given. Results. Most of the studied indicators of the dynamic component of the postural balance were reduced in the group of women with falls compared to the group of women without falls. Women with falls needed much more time to perform complex motor acts (p = 0,016), they showed lower speed of simple (p = 0,026) and tandem (p = 0,030) walking and higher step width in tandem walking (p = 0,016), and they also had a higher level of anxiety (р = 0,012) and a lower level of physical (p < 0,001) and psychological (p < 0,001) components of life quality. Conclusions. A group of women with falls showed a decrease in most of the studied indicators of the dynamic component of postural balance, subjectively experienced age, quality of life, as well as a higher level of anxiety and the rate of aging. Thus, we can assume that the decrease in the quality of the dynamic component of the postural balance can be illustrated by the deterioration of the subjective characteristics of the functional state of the body in elderly women.

The review considers some aspects of the development of negative effects when exposed to benzene, aluminum, manganese, nickel and copper. The present-day data of international and national studies devoted to the study of this problem in terms of the development of the toxic action of neurotoxicants are presented. The individual links of the development of pathological processes are considered, namely, violation of the generation, conduction and transmission of nerve impulses, neurogenesis as a result of activation of oxidative processes, potentiation of excitotoxicity, synaptic dysfunction and neuro-inflammation. The review provides a detailed description of the development of neurotoxic effects. It is shown that when exposed to benzene, an effect is formed in the form of a violation of the synaptic transmission of the nerve impulse associated with the development of oxidative stress in the nervous tissue. Manganese and aluminum oxides are capable of causing direct cytotoxic damage to neurons, followed by the formation of a neuroinflammatory response and disruption of the process of neurogenesis. The mechanism of development of synaptic dysfunction may be associated with the action of aluminum ions, zinc, iron and copper. The presented generalized materials on the etiopathogenetic effect of neurotropic chemicals allow to expand the scientific understanding of the mechanisms of the toxic effects of exogenous chemical environmental factors on the central nervous system.

CUSUP MAMAY'IN TOLTOY DESTANI’NDA ETNİK YAPI
Authors: ÇÖLOĞLU Raşit
Published: March 2020

Türk boylarının dünya
üzerinde geniş alanlara yayılmaları ve çok çeşitli uluslarla temas kurmaları
destanlarına da yansımıştır. İlk kayda geçirilen destanlardan Oğuz Kağan
Destanı dahil geçtiğimiz yüzyılda derlenen destanlar da bu niteliğini
korumuştur. Kırgız Türkleri destan geleneğini günümüzde en canlı haliyle devam
ettirmeleri bakımından Türk boyları içinde ayrıcalıklı bir yere sahiptir.
Özellikle Manas Destanı Kırgızların günlük hayatlarının bir parçasıdır. Manas
Destanı diğer Kırgız destanlarına göre etnik malzeme bakımdan çok zengindir .
Bu makalede Manas Destanı’nda yer alan halkların büyük çoğunluğuna yer veren
Toltoy Destanı etnik isimlendirmeler açısından analiz edilmiştir. Toltoy
Destanı Doğu Türkistanlı Manasçı Cusup Mamay’dan geçtiğimiz yüzyılın son
çeyreğinde derlenmiştir. Er Bagış’ın oğlu olan Toltoy Manas’ın oğlu Semetey ile
aynı dönemde yaşamış ve Kırgız halkını tehdit eden düşmanlarla mücadele
etmiştir.   Çalışmada tarihsel yöntem ve
metin analizi yöntemi kullanılmıştır. 
Ele alına etnik unsurların başında Cediger ve diğer Kırgızlar gelmekte,
ardından Kızılbaşlar, Türkmenler, Çürçütler, Kara Kıtaylar, Kalmuklar, Şibeler,
Kazaklar ve Ruslar gibi diğer halklara değinilmektedir. Çalışma sırasında adı
geçen halklar öncelikle tarihi açıdan incelenmiş, ardından Manas Destanı başta
olmak üzere diğer destanlarda nasıl işlendikleri anlatılmış, daha sonra da
Toltoy Destanı’nında bu halklarla ilgili kısımlar analiz edilmiştir. Sonuç
olarak Toltoy Destanı etnik unsurlarla ilgili verdiği bilgiler açısından Manas
Destanı’yla paralellik göstermekte ve onunla kıyaslandığında azımsanmayacak bir
malzeme sunmaktadır.
BAMSI BEYREK BOYUNUN TRABZON VARYANTI BASI BÖYREK ÜZERİNE BİR İNCELEME
Authors: KABAK Turgay
Published: March 2020

Ülkemizde
Dede Korkut çalışmaları iki ana kola ayrılabilir. Bunlardan biri Dede Korkut
kitabının nüshaları, diğeri de Dede Korkut boylarının Anadolu’daki varyantları
ile ilgili yapılan çalışmalardır. Bamsı Beyrek boyunun Trabzon varyantı ilk
olarak 1931 yılında Bartın Gazetesi’nde Ahmet Baha imzasıyla Hamamîzâde
İhsan’dan naklen neşredilmiştir. Gazetede köşe yazısı şeklinde yayınlanan bu
anlatı hem çok kısadır hem de eksiktir. Ancak 2003 yılında Trabzon merkeze
bağlı Bengisu (Eski adı Kisarna) köyünden Basi Böyrek adı ile derlenen elimizdeki
anlatı, gerek olay örgüsü gerekse de kahramanları ile tam anlamıyla bir Bamsı
Beyrek varyantıdır ve daha önce yapılan yayının eksik bıraktığı noktaları
tamamlamaktadır. Bu kapsamda araştırmanın amacı Bamsı Beyrek’in Trabzon
varyantının tamamını ilk defa bilim dünyası ile paylaşmak ve bu varyant üzerine
ilk bilimsel bir incelemeyi yapmış olmaktır. Araştırmanın deseni doküman
araştırması olarak yapılandırılmıştır. Araştırmanın örneklem yöntemi ise amaçlı
örneklemdir. Amaçlı örneklemde anılan Trabzon varyantı çalışılmıştır. Verilerin
analizinde ise doğrudan alıntılara dayanan betimsel analiz kullanılmıştır.
Araştırma sonucunda Trabzon varyantının olay örgüsü, kahramanlar, olağanüstü
olaylar ve şekil özellikleri bakımından diğer varyantlarla büyük oranda
benzerlikler göstermekle birlikte ayırt edici farklılıklar da taşıdığı tespit
edilmiş ve bu farklılıklar “Sözlü Kompozisyon Kuramı” ve “Performans (İcra)
Yöntemi” ile açıklanmıştır.
XIII. YÜZYIL BÜYÜK MOĞOL ULUSUNDA KAĞAN VE HAN UNVANININ KULLANIMINA DAİR BİR İNCELEME
Authors: KAYA Çetin
Published: March 2020

Tarihin her döneminde birçok devlette olduğu gibi XIII. yüzyılda yaşamış olan Moğol hükümdarları da bazı unvanlar kullanmışlardır. Bu açıdan bakıldığında Büyük Moğol Ulusu içerisinde hükümdarlar tarafından kullanılan unvanların başında kağan ve han gelmektedir. Böylelikle çalışmamızda bu unvanlar esas alınmıştır. Araştırma kapsamında çeşitli dil ve yazım şekilleri incelenerek onların; kullanımı ve birbirlerine olan üstünlükleri hakkında deliller aranmıştır. Bu hususta XIII. yüzyıldaki ilk hükümdarları Cengiz’den başlayarak sırasıyla Ögödey, Göyük, Möngke ve Kubilay gibi Büyük Moğol Ulusu hükümdarları incelenip onların dönemlerinde oluşturulmuş belgeler ayrıntılı olarak taranmıştır. Taranan bu belgeler içerisinde yazıtlar, yarlıklar (fermanlar), kronikler, nümizmatik veriler ve bazı tarihi kalıntılar bulunmaktadır. Söz edilen kaynaklardan elde edilen veriler ışığında unvanların ortaya çıkış zamanlarından kısaca bahsedilmiştir. Ayrıca incelediğimiz dönemdeki kullanımları hakkında birtakım çıkarımlarda bulunulmuştur. Bu araştırmalar neticesinde elde edilen çıkarımlardan biri dönem itibarı ile iki unvanın eş zamanlı kullanımlarının olduğu şeklindedir. Buna ek olarak araştırılan iki unvan arasındaki tek farkın yazım şekli olduğu ve birinin diğerine her hangi bir üstünlüğünün olmadığı görüşüdür.
