Authors: Defri Ifwarisan , Irfansyah Aditya , Sudarsono Sukma , SAPUTRO ERWAN
Published: December 2021

Sugar alcohol or sorbitol is a derivative product of carbohydrates, namely glucose through the hydrogenation process with hydrogen gas. The glucose used comes from flour, because the carbohydrate content in tapioca flour is considered the highest compared to other flour ingredients. Before the hydrogenation process is carried out, tapioca flour is enzymatically hydrolyzed so that the starch is broken down into glucose. The process of making sorbitol can be done in two ways, namely the electrolysis reduction process and the hydrogenation process with the help of a nickel catalyst. This literature study aims to determine the technology for making sorbitol and its advantages and disadvantages, both in terms of product and process, so that it can be used as a reference in selecting processes in sorbitol manufacturing plants. The catalytic hydrogenation process has advantages, namely the resulting yield is greater and the operating costs are relatively cheaper. The catalytic hydrogenation process also has several disadvantages, namely that it requires good safety handling because it requires high pressure in the process.

Pengaruh Media Arang Kayu Bakau Mangrove Dan Arang Kayu Asam Pada Proses Perlakuan Carburizing Terhadap Sifat Mekanik Baja Karbon ST-37
Authors: Arifandi Rico , Pohan Gerald Adityo
Published: December 2021

In the military field, tank is armored fighting vehicles that move using chain-shaped wheels. The tread of the tank chain is a component to tread and move so that it requires tougher properties on the surface and has ductile and tough properties on the inside and is more resistant to wear on the surface. The development of tank chain production materials is necessary for the independence of national defense and security as well as reducing dependence on imports. Imported tank chain hardness value 28 HRC or 286 HV.

In this research, the objective of this research is to increase the surface hardness of the steel by carburizing the initial material, especially the low carbon steel ST-37. The carburizing treatment process is a method of adding carbon content in steel using solid media. The carbon media used were mangrove charcoal and tamarind wood charcoal using calcium carbonate (CaCO3) catalyst at a constant heating temperature of 900ºC, variations in holding time of 30 minutes, 60 minutes and 90 minutes, cooled rapidly with water media. Then performed an analysis of the effect of the type of wood charcoal on the mechanical properties of carbon steel ST-37. The results obtained will be applied to the tank chain tread production process.

The results of the micro structure of martensite and the highest hardness value were found in the holding time of 60 minutes of mangrove charcoal media with the microstructure results of 63.8% martensite, 36.2% bainite and a hardness value of 453.1 HV. The highest toughness value is found in the holding time of 60 minutes of tamarind wood charcoal media with an impact price (HI) of 0.4345 J/mm2. The difference between the impact test results of tamarind charcoal media with mangroves is not too significant. The higher the martensite phase, the higher the hardness value. However, there is also a bainite phase which can increase the toughness of the steel which will be used as a tread chain production material.

Link-Layer Retransmission-based Error-Control Protocols in FSO Communications: A Survey
Authors: Le Hoang
Published: December 2021

 Free space optical (FSO) communication has established a reputation for itself capable of delivering high-speed data services over long distances without exhausting radio frequency (RF) resources.

FSO communication can be considered in different network scenarios, including inter-satellite/deep-space links, ground-station/vehicles, satellite/aerial links, and terrestrial links. It is expected to be one of the key enabling technologies for the next generation of 6G wireless networks. Nevertheless, despite the great potential of FSO communications, its performance suffers from various limitations and challenges: atmospheric turbulence, clouds, weather conditions, and pointing misalignment. The error-control solutions, including physical layer (PHY) and link-layer methods, aim to mitigate the transmission errors caused by such adverse issues. While the existing surveys on error-control solutions in FSO systems primarily focussed on the PHY methods, we instead provide a review of link-layer solutions. In particular, we conduct an extensive literature survey of state-of-the-art retransmission protocols, both automatic repeat request (ARQ) and hybrid ARQ (HARQ), for various FSO communication scenarios, including point-to-point terrestrial, cooperative, multi-hop relaying, hybrid FSO/RF, satellite/aerial, and deep-space systems. Furthermore, we provide a survey of recent literature and insightful discussion on the cross-layer design frameworks related to link-layer retransmission protocols in FSO communication networks. Finally, the lessons learned, design guidelines, related open issues, and future research directions are exposed.
Origins and development of the Maria Montessori’s mathematical proposal
Authors: Boscolo Alessandra , Crescenzi Martina , Scoppola Benedetto
Published: December 2021

The introduction of complex mathematical concepts through perceptual and sensorial hands-on experiences is one of the most relevant aspects of the Montessori method proposal. This article aims to investigate the origins of the Montessori’s profound interest for mathematics, studying the history of the education of mathematics, after the unification of Italy, in which her school education took place. Her key concepts and beliefs about the learning of mathematics and, furthermore, the evolution of her proposal will be illustrated through the analysis of her main publications, both the generalist and the specialized ones in the field of mathematics (Psicoaritmetica and Psicogeometria), and handwritten notes about the lessons of XVI° international course, held in Rome in 1931, which the Opera Nazionale Montessori acquired from her students’ archives. Finally, an overview of the actualization of the Montessori method in the contemporary research will be explained, particularly focusing on the neuroscientific discoveries which have proved the effectiveness of the Montessori proposal to empower the cognitive processes involved in the development of mathematical thinking.
The Milan 1911 Conference on Methods: a ‘node’ in the history of diffusion of the Montessori Method
Authors: Gabusi Daria
Published: December 2021

This contribution is a first attempt to look at a step of the history of the diffusion of the Montessori method in Italy. It looks at a phase between 1910 and 1911, strictly connected to the evolution of Maria Montessori’s relationships with members of secular and radical-masonic elites. In particular, in April 1911 an important conference – For an Italian Method in Kindergartens – was organised in Milan: it represented the zenith of the debate on childhood pedagogy, nurtured by the experiences (within the Froebelian approach) of Agazzi and Montessori methods of education. Originally organized – probably – to promote the knowledge and diffusion of the Montessori method, the conference – in parallel with the breakup of Montessori’s relationship with the radical political movements close to the pedagogist Luigi Credaro – then took another direction, leading subsequently to very different results from the desired ones.
Einaudi and Cooperative Education Association (MCE). Traces of a project for the elementary school (1966-67)
Authors: Vigutto Lucia
Published: December 2021

The aim of this paper is to show the editorial relationship between the Einaudi publishing house and the Cooperative Education Association (MCE) during the second half of the Sixties. The members of the Association were looking for an editor willing to spread their pedagogical instances for the renewal of the Italian school and they found it in Einaudi. Thanks to the study of the correspondence and the documentation preserved in the Giulio Einaudi Editore Historical Archive, it has been possible to analyze a project of textbooks for the elementary school, made in collaboration with relevant members of the Association such as Gianni Rodari, Mario Lodi, Giuseppe Tamagnini and Bruno Ciari. The collections were never published, in part for financial reasons, but also because of the rising debate around the textbooks. The opinion of the Association in the late Sixties was changed: the point was not to renew the textbooks but to abolish them. Understanding the reasons of the end of this project might help to clarify the pedagogical impact of the cultural and social changes of that period, the relationship between education and politics. Moreover, it is not by chance that from the ashes of this project took shape The wrong country (Il paese sbagliato), a masterpiece written by Mario Lodi destined to become a classic for the history of education.

Este estudo visa investigar efeitos da ação do Estado na área da saúde no Brasil considerando seus determinantes sociais. A metodologia é de abordagem quantitativa, tendo como base 438 regiões de saúde brasileiras. A técnica estatística principal adotada foi a análise de regressão logística múltipla. Como indicador de resultado de saúde, utilizou-se a Taxa de Mortalidade Infantil (TMI), e, para mensurar a ação do Estado, indicadores do gasto público e da oferta e cobertura de ações e serviços de saúde. Todas as dimensões da ação do Estado apresentaram efeitos estatisticamente significativos para a diminuição das chances da região apresentar TMI alta. O único indicador da ação do Estado que apresentou efeito significativo em todos os cenários foi cobertura pré-natal. Observou-se também que a situação socioeconômica regional possui efeito substancial e significativo em todos modelos testados. Assim, para uma possível diminuição das desigualdades em saúde, devem ser levados em conta determinantes das desigualdades sociais. No entanto, ressalta-se que a ação do Estado na área da saúde, somente, apresenta potencialidade para agir na determinação da condição de saúde da população em cada região de saúde, mesmo considerando fatores socioeconômicos.

A study done in Hong Kong since 2003 using a simple twin herb formula for the prevention of progress of atherosclerosis in 4 different groups of patients with cardiovascular diseases, and using the same surrogate marker IMT as the objective indicator, showed comparable results within a much shorter period of 6-12 months. Extensive laboratory tests have also been completed to verify the bioactivities of the twin herb formula on anti-inflammation, anti-oxidation, endothelial protection and regenerative capacity related to atherosclerosis.

It is suggested that before more potent therapeutic measures become available to slow atherosclerosis progression are available. The purpose of the paper is to compare the Mediterranean Diet for long term consumption and selective herbal preparations for shorter term or intermittent scheduled intake, and recommend to high-risk individuals.
Müzik Öğretmeni Adaylarının Bireysel Çalgı Seçimini Etkileyen Unsurların Öğrenci Görüşleri Doğrultusunda Değerlendirilmesi
Authors: TOPALOĞLU Taner
Published: December 2021

Araştırmada, Müzik Eğitimi Ana Bilim Dalı’nda okuyan müzik öğretmeni adaylarının görüşleri doğrultusunda meslek eğitimi öncesinde ve meslek eğitiminde bireysel çalgı seçimini etkileyen faktörleri, çalgı seçiminin bireysel çalgı eğitiminde akademik başarıya olan etkileri ve mesleki yaşantılarında bireysel çalgılarını etkin bir şekilde kullanabilme motivasyonlarını tespit etmek amaçlanmıştır. Bu amaçla çalışmada, nitel ve nicel yöntemlerin birlikte kullanıldığı karma yöntem kullanılmıştır. Nitel veriler 6 açık uçlu sorudan oluşan yarı yapılandırılmış görüşme formu, nicel veriler ise 4 kapalı uçlu seçmeli sorular ile elde edilmiştir. Araştırma sonucunda mesleki müzik eğitimi öncesinde kadın öğrencilerin çoğunlukla keman, flüt ve gitar çalgılarına; erkek öğrencilerin ise çoğunlukla gitar, keman ve bağlama çalgısına eğilim gösterdikleri; öğrencilerin bu çalgıları tercih etmelerinde sırasıyla medya, aile, arkadaş çevresi ve müzik öğretmeninin büyük rolü olduğu anlaşılmıştır. Meslek eğitiminde ise öğrencilerin bireysel çalgı seçiminde öğrencinin talep ettiği bireysel çalgının kurul tarafından reddedilme sebeplerinin çoğunlukla öğretmen sayısının yetersizliğinden kaynaklı sınırlı öğrenci kontenjanından ve öğrencilerin fiziki yapısına uygun olmamasından kaynaklandığı anlaşılmaktadır. Öğrencilerin çalgıya ilişkin akademik başarıyı etkileyen faktörlerin ise öğretmen faktörü ve öğrencinin çalgısını sevmesine ilişkin motivasyonuna bağlı olduğu, öğrencilerin büyük bir çoğunluğunun çalgı performansı konusunda özgüvene sahip olmalarından ve çalgılarını sevmelerinden dolayı mesleki yaşantılarında çalgılarını etkin bir şekilde kullanabilecekleri görüşlerine sahip oldukları sonuçlarına ulaşılmıştır.
On the Verge Between Cocreation and Codestruction: The Interesting Case of a Greek Traditional Cultural Event
Authors: Glyptou Kyriaki
Published: December 2021

Traditional cultural events provide unique opportunities for resident-attendee destination experience and image cocreation, yet the cognitive, perceptual, and behavioral disparities between these key actor groups remain rather sparse. Focusing on the process rather than the outcome
of cocreation, this article adopts a Service-Dominant Logic (SDL) to explore the underlying dynamics of social and economic actor encounters and their role in service value and image cocreation and destination resource management. More specifically, the study applies a mixed-method approach
to study the interface of social and psychological carrying capacity during the Easter Rocket War in Chios (Greece). Building on the particularities of this traditional event, the research identifies variables that trigger cognitive and perceptual conflicts of interests that may jeopardize
an event's and a destination's image cocreation process, resulting in its codestruction. Research findings contribute to the broader event image cocreation and destination branding body of literature, though the exploration of the underlying dynamics of multistakeholder and multiattribute
event dimensions (cultural, spiritual, historical, recreational). From a managerial perspective, research findings aim to inform destination planning and decision-making processes that dictate event viability, publicity, and multistakeholder satisfaction.
Follow the leader: Child-led inquiries to develop science learning of young children
Authors: Roberts Pauline
Published: December 2021

Science education in the early years has been found to be lacking when compared to other content areas, specifically numeracy and literacy. It has been suggested that this lack of opportunity for young children to learn science is due to educator’s lack of confidence to teach science, fuelled by concerns regarding a reduced understanding of science concepts.  For young children, however, science is everywhere and is embedded in all aspects of their lives as they explore and interact to make sense of the world around them. Given this natural connection to science, it is important for educators to notice and respond to children’s interest to encourage science learning to occur. This paper reports on an exploratory research study in which children took the leading role in inquiry-based interactions during off-site school days that took place within a metropolitan city zoo. Through the collection of observations and interactions with the research, several inquiries were documented. The children challenged the educators within the program to follow up on questions posed by them and engage the children across a broad age range in an inquiry to answer these questions.

Research in young children’s ideas, representations, and pre-conceptions about the natural and technical world has a long history. Most of the studies in the field have used individual, semi-structured interviews as a methodological technique to generate and collect empirical data. However, less is known about how tracing procedures can come in line and be incorporated into everyday educational reality in early childhood settings in a way that reflects young children’s interests and needs. The present study uses dramatic play to trace young children’s thinking in science and advance their science learning experiences. The study focuses on a science concept young children are familiar with in everyday life though has not been thoroughly studied in the literature yet: thermal insulation. Empirical data from 6 preschoolers in Greece are presented. Qualitative data were collected through recordings of children’s dialogues, children’s drawings, field notes from the early childhood teachers, and photographs. The findings revealed that during their dramatic play children a) developed basic argumentation to express their thinking about the phenomenon; b) related the phenomenon with the thermal condition and changes in temperature; c) identified materials and objects with insulating properties and distinguish them from others with non-insulating properties, and d) came to the conclusion that the use of amplified insulation materials can lead to better insulation results. The outcomes of the study add to the research methodology in early childhood science education and inform practice providing a pedagogical framework that balances between play-based pedagogies and advanced learning outcomes in science for young learners.
КЛІНІКО-ФАРМАКОЛОГІЧНІ ОСОБЛИВОСТІ ВИКОРИСТАННЯ АНТАГОНІСТІВ АЛЬДОСТЕРОНУ У ХВОРИХ З ГІПЕРТОНІЧНОЮ ХВОРОБОЮ

Published: December 2021

Вступ. Гіпертонічна хвороба – надпоширене захворювання з тенденцією до щорічного росту. Вона призводить до великої кількості морбідних станів, має багато проявів та викликає численні ускладнення. З метою її лікування продовжують розроблятися та впроваджуватися нові фармакологічні препарати які попереджають швидке прогресування захворювання, мають кращий профіль безпеки, а також не погіршують якість життя пацієнтів. Гіпотензивна активність, переносимість при тривалому застосуванні та цінова доступність антигіпертензивних препаратів продовжують залишатися визначальними при обранні конкретної фармакотерапії.Мета. Порівняти ефективність, безпечність та особливості фармакологічної дії при застосуванні антигіпертензивних препаратів спіронолактону та еплеренону.Матеріали та методи. Бібліографічний – проведено теоретичний аналіз та здійснено узагальнення даних літератури, проаналізовано фактичний вміст. При дослідженні використано анкетно-опитувальний метод, а також – опис, аналіз, реферування.Результати та їх обговорення. Велику увагу клініцистів останнім часом привертають сечогінні препарати з групи антагоністів альдостерону у зв’язку з їх достатньою діуретичною активністю та високою безпечністю. Препаратом нового покоління слід вважати еплеренон, який проявляє свою ефективність та безпечність не лише при лікуванні артеріальної гіпертензії, а й у випадку інших захворювань – альбумінурії при цукровому діабеті ІІ типу, хронічної хвороби нирок та при гіперальдостеронізмі.Фармакологічні властивості еплеренону наділили його більшою специфічністю до блокування рецепторів мінералокортикоїдів. При лікуванні артеріальної гіпертензії еплеренон не поступався у антигіпертензивній активності своєму попереднику із цієї фармакологічної групи – спіронолактону, проте рідше викликає певні небажані ефекти, які часто зустрічаються при його застосуванні.Висновки. Еплеренон безпечніший від свого попередника – спіронолактона, має високу ефективність, що дає можливість внести цей препарат у лінію фармакологічних засобів для лікування хвороб, описаних в даній статті.
The
armed resistance to the Taliban regime in Afghanistan
Authors: Shay Shaul
Published: December 2021

The main violent threat to the Taliban regime comes from the Islamic State in Khorasan Province (ISIS-K) armed group, but the Taliban regime will also have to deal with armed resistance from ethnic groups in Afghanistan that already feel threatened by the new regime. ISIS – K presents a serious challenge to the Taliban's regime in Afghanistan as the group operates in cells across the country. ISIS – K doesn't possess
the capabilities to overthrow the Taliban government. Still, they can damage the credibility of the Taliban, which has claimed that it is the only group that can bring peace and stability to the country. The ethnic
groups (the Shia Hazara and Uzbek and Tajik ethnic groups) are already under pressure in Taliban-controlled Afghanistan. These groups that in the 1990s formed the "Northern Alliance" that fought against the Taliban
are organizing to defend themselves against Islamic State attacks and Taliban persecution and in the future could become a significantly armed
opposition to the Taliban regime.
Optimizing Perimeter Surveillance Drones to enhance the security system of unmanned aerial vehicles
Authors: Al-Bkree Mahmod
Published: December 2021

This
work is to optimize perimeter surveillance and explore the distribution of
ground bases for unmanned aerial vehicles along the Jordanian border and
optimize the set of technologies for each aerial vehicle. This model is part of
ongoing research on perimeter security systems based on unmanned aerial
vehicles. The suggested models give an initial insight about selecting
technologies carried by unmanned aerial vehicles based on their priority; it
runs for a small scale system that can be expanded, the initial results show
the need for at least four ground bases along the length of the border, and a
selected set of various technologies for each vehicle.
PDSTD - The Portsmouth Dynamic Spontaneous Tears Database
Authors: Küster Dennis , Baker Marc , Krumhuber Eva G.
Published: December 2021

The vast majority of research on human emotional tears has relied on posed and static stimulus materials. In this paper, we introduce the Portsmouth Dynamic Spontaneous Tears Database (PDSTD), a free resource comprising video recordings of 24 female encoders depicting a balanced representation of sadness stimuli with and without tears. Encoders watched a neutral film and a self-selected sad film and reported their emotional experience for 9 emotions. Extending this initial validation, we obtained norming data from an independent sample of naïve observers (N = 91, 45 females) who watched videos of the encoders during three time phases (neutral, pre-sadness, sadness), yielding a total of 72 validated recordings. Observers rated the expressions during each phase on 7 discrete emotions, negative and positive valence, arousal, and genuineness. All data were analyzed by means of general linear mixed modelling (GLMM) to account for sources of random variance. Our results confirm the successful elicitation of sadness, and demonstrate the presence of a tear effect, i.e., a substantial increase in perceived sadness for spontaneous dynamic weeping. To our knowledge, the PDSTD is the first database of spontaneously elicited dynamic tears and sadness that is openly available to researchers. The stimuli can be accessed free of charge via OSF from https://osf.io/uyjeg/?view_only=24474ec8d75949ccb9a8243651db0abf.
