Learning trajectory berbasis proyek pada materi definisi himpunan
Authors: Astuti Widi , Wijaya Ariyadi 
Published: May 2022

Tujuan penelitian ini adalah untuk mendeskripsikan learning trajectory ber­basis proyek yang dilalui siswa untuk memahami definisi himpunan. Penelitian desain ini menggunakan model Gravemeijer dan Cobb dengan tahapan yang terdiri atas: (1) preparing for the experiment yang mencakup penyusunan hypo­thetical learning trajectory (HLT); (2) design experiment yang mencakup pe­laksanaan pembelajaran berdasarkan HLT yang telah dirancang; dan (3) retro­spective analysis, yaitu membandingkan HLT dengan pembelajaran yang dilak­sanakan. Pengembangan HLT menjadi learning trajectory diperoleh melalui serangkaian aktivitas yang dilaksanakan dengan pengumpulan data melalui dokumentasi, observasi, dan wawancara dengan guru dan siswa untuk meng­klarifikasi dan mengonfirmasi alur belajar. Hasil penelitian mengindikasikan bahwa pembelajaran berbasis proyek dapat memfasilitasi siswa dalam mema­hami definisi himpunan. Learning trajectory definisi himpu­nan berbasis proyek diperoleh melalui serangkaian aktivitas dengan empat level pemodelan. Level situasional berupa aktivitas survei kumpulan objek di sekolah. Pada level refe­rensial, istilah “ciri-ciri yang sama”, “dapat didefinisikan”, dan “objek tambah­an”, dan “kesepakatan” muncul melalui diskusi. Pada level generalisasi, siswa me­nuliskan himpunan dalam bentuk yang lebih umum. Ter­akhir, pada level for­mal, pemahaman yang siswa peroleh dari setiap aktivitas merupakan modal un­tuk membangun konsep tentang definisi himpunan.Project-based learning trajectory on the definition of the set topicAbstractThis research aimed to describe the project-based learning trajectory pass­ed through by students to understand the set definition. This design research used Gravemeijer and Cobb model with stages: (1) preparing for the experiment that includes developing hypothetical learning trajectory (HLT); (2) design of expe­riments which includes learning practices implementation based on the deve­loped HLT; and (3) retrospective analysis, which was to compare HLT with learning practices. The development of HLT into a learning trajectory was ob­tained through a series of activities carried out by collecting data through docu­mentation, observation, and interviews with the teacher and students to clarify and confirm the learning trajectory. The results indicated that project-based learning could facilitate students to understand the definition of set. The lear­ning trajectory was obtained through a series of acti­vities with four levels of modeling. The situational level was in the form of a survey activity aimed to collect objects in the school area. At the referential level, the terms “common features”, “definable”, “additional objects”, and “agree­ment” emerged thro­ugh discussion. At the generalization level, students wrote the set in a more general form. Lastly, at the formal level, the under­standing that students get from each activity was a provision to construct a concept about set definition.

Published: May 2022

El mercado de helados está en constante expansión y diversificación. Una muestra de ello es que se están diseñando diversas opciones de helados para el segmento de adultos, entre las cuales el helado con licor se abre camino como una opción interesante. Sin embargo, la adición de este ingrediente afecta negativamente algunos parámetros de calidad del helado. En esta investigación, buscando mantener los parámetros de calidad esperados por los consumidores, se evaluó el efecto de la adición de emulsionantes-estabilizantes en la calidad sensorial y fisicoquímica de un helado con licor utilizando un diseño de mezcla simplex-centroide, en el cual se prepararon siete formulaciones de helado por triplicado. De acuerdo con el diseño de mezclas, se combinaron metilcelulosa, goma guar y/o carragenina en lotes de helado de aproximadamente un litro. Se midieron los °Brix, la densidad, el color, el pH y el punto de congelación de la mezcla de helado madurada durante 24 horas. También se evaluaron la textura, el porcentaje de fusión, el tiempo de caída de la primera gota y el overrun del helado final. Finalmente, se realizó la evaluación sensorial utilizando pruebas de aceptación y preferencia con un panel de 141 consumidores. El efecto de los estabilizantes sobre las propiedades fisicoquímicas se analizó mediante gráficos de contorno y la formulación óptima se determinó con base en parámetros de calidad y análisis sensorial. Se concluye que la formulación óptima está compuesta por 12,32 % de metilcelulosa, 71,84 % de goma guar y 15,83 % de carragenina, para formar la red de gel que mantendrá al alcohol etílico dentro de la matriz, evitando separaciones no deseadas y manteniendo las propiedades fisicoquímicas, funcionales y sensoriales dentro los parámetros establecidos y esperados por el consumidor.

Background
Dry eye (DE) is a chronic inflammatory disease of the ocular surface of the eye that affects millions of people throughout the world. Smartphone use as an effective health care tool has grown exponentially. The “Dry eye or not?” app was created to evaluate the prevalence of symptomatic DE, screen for its occurrence, and provide feedback to users with symptomatic DE throughout Thailand.

Objective
The purpose of this study was to compare the prevalence of symptomatic dry eye (DE), blink rate, maximum blink interval (MBI), and best spectacle-corrected visual acuity (BSCVA) between people with and without symptomatic DE and to identify risk factors for symptomatic DE in Thailand.

Methods
This cross-sectional study sourced data from the “Dry eye or not?” smartphone app between November 2019 and July 2020. This app collected demographic data, Ocular Surface Disease Index (OSDI) score, blink rate, MBI, BSCVA, and visual display terminal (VDT) use data. The criterion for symptomatic DE was OSDI score ≥13.

Results
The prevalence of symptomatic DE among individuals using this smartphone app in Thailand was 85.8% (8131/9482), with the Northeastern region of Thailand having the highest prevalence, followed by the Northern region. Worse BSCVA (median 0.20, IQR 0.40; P=.02), increased blink rate (median 18, IQR 16; P<.001), reduced MBI (median 8.90, IQR 10.80; P<.001), female sex (adjusted OR 1.83; 95% CI 1.59-2.09; P<.001), more than 6 hours of VDT use (adjusted OR 1.59; 95% CI 1.15-2.19; P=.004), and lower than bachelor’s degree (adjusted OR 1.30; 95% CI 1.03-1.64; P=.02) were significantly associated with symptomatic DE. An age over 50 years (adjusted OR 0.77; 95% CI 0.60-0.99) was significantly less associated with symptomatic DE (P=.04).

Conclusions
This smartphone DE app showed that the prevalence of symptomatic DE in Thailand was 85.8%. Signs and risk factors could be also evaluated with this smartphone DE app. Screening for DE by this app may allow for the development of strategic plans for health care systems in Thailand.
Development of Best Practice Guidance on Online Peer Support for People With Young Onset Dementia: Protocol for a Mixed Methods Study
Authors: Gerritzen Esther Vera , McDermott Orii , Orrell Martin 
Published: May 2022

Background
Many people with young onset dementia (YOD) may feel isolated. Peer support has the potential to improve social health, but the inconsistent availability of age-appropriate, in-person (peer) support services for people with YOD suggests that many people with YOD miss out on the potential benefits. Online peer support could be useful, as it overcomes geographical barriers, offers a variety of options, and adjusts to various needs and preferences.

Objective
Our study aims to develop evidence-based best practice guidance on online peer support for people with YOD and group facilitators to improve online peer support for people with YOD.

Methods
Our mixed methods study consists of 4 phases and follows the guidelines of the Medical Research Council on complex interventions. Each phase consists of multiple substudies. The study focuses on the development stage of the Medical Research Council framework and additionally develops a plan for the feasibility/piloting, evaluation, and implementation stages. The participants are people living with YOD and peer support facilitators. The qualitative research methods include interviews, focus groups, and open questions in a web-based survey. The quantitative methods include a web-based survey consisting of existing outcome measures.

Results
The study is funded by the European Union’s Horizon 2020 research and innovation program under the Marie Skłodowska-Curie Actions – Innovative Training Networks (H2020-MSCA-ITN-2018; grant agreement number: 813196), and it received ethical approval from the London Bromley Research Ethics Committee (reference number: 21/LO/0248) in April 2021. Recruitment started in May 2021. Data collection and analysis are expected to be finished by September 2022.

Conclusions
The best practice guidance can provide people with YOD with tailored and evidence-based information about online peer support, and it will be disseminated locally (in the United Kingdom) and internationally through dementia organizations, research networks, and academic institutions.

Pengaruh penambahan kacang hijau (vigna radiata (l.) R. Wilczek) pada fermensi susu oleh lactococcus lactis nbrc 12007
Authors: Widawati Raras Ahlul , Retnaningrum Endah 
Published: May 2022

The high content of α-galactooligosaccharide in mung beans has the potential for supporting the growth of Lactic Acid Bacteria (LAB), therefore it can be developed as fermented plant-based milk that substituted Ultra High Temperature (UHT) milk. The purposes of this research is to investigate the effectiveness of LAB Lactococcus lactis NBRC 12007 in the fermentation process of mung bean milk and to observe the quality differences of fermented mung bean milk with UHT milk. Previously, preparations were made for starter L. lactis NBRC 12007 in MRSB medium and then sub cultured to UHT milk. Furthermore, 3% of the culture was inoculated into each of the mung bean milk substrate and UHT milk as a starter for the fermentation process and incubated for 24 hours at 37oC. During this process, the effectiveness of LAB was tested (total cell, total acid, total protein, pH, antibacterial) and the quality test of fermented products (organoleptic and physical). Based on total cells, total acid, total protein, pH, and antibacterial test findings, fermented mung bean milk products had a higher value than UHT milk products. During the process, it was proven that L. lactis NBRC 12007 had high effectiveness in producing and improving the quality of fermented mung bean milk compared to UHT milk. It is assumed that the content of oligosaccharides supports the growth of LAB and the fermentation process.
Emerging green routes to nanocellulose
Authors: Ciriminna Rosaria , Gharhemani Mina , Karimi Babak , Pagliaro Mario 
Published: May 2022

Nanocellulose is an exceptional biomaterial whose industrial
applications in widely different sectors and technologies so far were
chiefly limited by the high cost of its multi-step extraction routes.
Extraction methods of cellulose nanocrystals or nanofibers, indeed,
generally involve energy-intensive mechanical treatment of wood pulp,
treatment with concentrated H2SO4 to obtain cellulose nanocrystals, or
chemical oxidation of the nanofibers followed by mechanical fibrillation
of the partly oxidized fibers. In the last decade (2011-2021) a number
of new green routes to cellulose nanofibers and nanocrystals have been
developed. This study provides a critical outlook of such emerging green
new routes to this versatile and safe bionanomaterial that once
sustainably produced, preferably from low cost cellulosic biowaste, will
become uniquitous in a number of different industrial products.
Establishment of interlaminar structure and crack propagation in carbon fiber reinforced epoxy composites by interleaving CNTs/PEK-C film
Authors: LI Hongfu , YAO Jiawei , WU Ying , NIU Kangmin 
Published: May 2022

The synergistic combination of carbon nanotubes (CNTs) and ductile
thermoplastic resin has shown large potential in the improvement of
fracture resistance for the epoxy matrix composites using the
interleaving toughening method in recent years. The hybrid structure of
CNTs and thermoplastic resin in interlayers affects directly the
interlaminar structure and the resultant crack propagation path of the
interleaved composites. In this work, the CNTs and thermoplastic
polyetherketone-cardo (PEK-C) were used to prepare the interlayer with
different hybrid structures to interleave the carbon fiber reinforced
epoxy composites and the influence of hybrid structure on the
interlaminar structure and the fracture toughness was investigated. The
results showed that PEK-C/CNT/PEK-C sandwich interlayer produced the
best toughening effect in mode I interlaminar fracture toughness
(G) and the G was
446.76 J/m , increased by 138.11% compared to blank
composites, which benefited from the multilayered structure in the
interlaminar region formed during curing process and the resultant
tortuous crack propagation.

Abstract
In recent years, communication using electromagnetic (EM) radiation became an integral part of our lives. As a result, there is a large number of base transceiver stations (BTSs) which act as a source of high EM exposure for inhabitants mainly in the “hot-spot” areas. They employ higher values of radiation, thus, providing potentially harmful effects on living or working environment. The aim of this pilot study was to study a distribution of hot-spots and EMF power in a vicinity of BTSs. BTS was located in an extra-village area at least 500 m away from the nearest city or surrounded villages in the district of Martin. The targeted area of EM radiation from the BTS was divided into two smaller zones, the right and the left. For a better visualization, topographic maps were created. Using spectral analyzer Aaronia Spectran HF-6085, intensities of EMF within the frequency range from 880 – 960 MHz (GSM900) were recorded. Maximum values of EMF power flux density were 146.827 μW/m2 in horizontal and 96.448 μW/m2 in vertical plane. Minimal va lues were 0.052 μW/m2 in horizontal and 0.179 μW/m2 vertical plane respectively. The maps revealed two hotspots in the left zone and also two (smaller and larger) hotspots in the right zone. Our values were below the actual limits given by the Slovak Republic and the International Commission for Non-Ionizing Radiation Protection (ICNIRP) safety guidelines. However, the values from the hotspots were above the limits suggested by the BioInitiative Report. Our results indicate an elevation of EMF values in the hot-spots even in the extra-village areas. Further studies are needed to analyze in detail EMF parameters in the hot-spots, and their effects on living and working environments.
Lantana charcoal as potent carrier material for Azotobacter chroococcum
Authors: Mankar Mangesh Kumar , Sharma U.S. , Sahay Sanjay 
Published: May 2022

Abstract

Azotobacter chroococcum is a universally accepted plant growth-promoting rhizospheric bacterium, which, as a biofertilizer, helps to increase the nitrogen level, solubilize the unavailable form of phosphorus, ensure growth-promoting metabolites, and control pathogenic microbes in the soil. A good strain of plant growth-promoting rhizobacteria (PGPR) needs to be produced, formulated, transported, stored, and distributed to the agriculture field. During all these operations, bacterial inoculants are transferred via a carrier material. One of the important challenges in biofertilizer technology is to ensure stability of the bacteria in the carrier. The study aimed to assess a novel carrier Lantana charcoal (LC; obtained from Lantana camara biomass), as compared to some currently available carriers. LC exhibited higher carbon content, low N2 content, neutral pH, and, above all, higher water-holding capacity, making it a suitable carrier material for A. chroococcum and possibly other PGPR. As a carrier, it showed no contamination during storage, exhibited the highest moisture content and moderate culture holding coefficient, and supported the highest colony-forming units per gram at the end of the storage period. Thus, LC cannot only serve as a better carrier, but its large-scale application would also ensure a reasonable use of this weed.
The Mortgaged Miracle Social Stratification in Contemporary Estonian Cinema
Authors: Hoyer Dirk 
Published: May 2022

Abstract
According to recent OECD statistics, Estonia is the European Union country with the highest income inequalities. Among all the ex-Warsaw bloc states, the Baltic country also has the highest household debt. Despite these dire socio-economic indicators, Estonia’s path to economic development, the adaptation of the purest forms of neoliberalism to be found in Europe, is often hailed among economists. Former prime minister Mart Laar, one of the key architects of what was dubbed by some the Estonian Economic Miracle, admitted that his guideline for the post-Soviet economic reform (and the only book he read on economics) was Milton Friedman’s Free to Choose.
How does inequality, social exclusion and growing social stratification manifest itself in Estonian contemporary cinema? The debut films of three directors, Vallo Toomla, Mihkel Ulk and Toomas Hussar, which all have a contemporary setting, address the neoliberal transformation process to various degrees. All three debut films are genre films: Mushrooming (Hussar, 2012) is a comedy, Zero Point (Ulk, 2014) a high-school drama and The Pretenders (Toomla, 2016) a thriller. None of the films directly addresses the social stratification of Estonian society. The films engage the subject with a low level of politicization, yet each of the films is a chronotope of the engagement of the film medium with society. Especially the question of individual responsibility to society, accountability for social exclusion and possible alternatives to neoliberalism are either addressed in an apprehensive way or, through their absence, deemed irrelevant. How did Friedman’s claim that economic freedom equals political freedom, that the market is the only effective tool and that self-interest is the only acceptable driving force in society affect the Estonian cinemascape? This article argues that the chronotope of contemporary cinema in the small Baltic country is an outopia, a no-place, in which alternatives to the status quo have no more reference points. The outopian outlook on society is manifested either by an absence in the belief of the integrity of politics and media (Mushrooming), by an implicit acceptance of social exclusion (Zero Point) or by the acknowledgement that faking material wealth is the only tool for maintaining social relationships (The Pretenders).
An Analysis of Concentration and Competition in the Banking Sector of the Republic of Serbia

Published: May 2022

Abstract
The degree of the banking sector concentration is a structural variable and refers to the number of banks in the system and the degree of their market power. The importance of measuring concentration in the banking sector stems from the causal relationship between the market structure and the competitive behaviour of market participants. Traditional models measuring the banking sector competition proceed from the market structure and concentration measures. In contrast, modern approaches to measuring competition rely on non-structural models and analysis of the behaviour of market participants. The paper analyzes the degree of concentration and competition in the banking sector of the Republic of Serbia. The traditional and most frequently used indices, the concentration ratio and the Herfindahl-Hirschman index, are used to measure concentration. The values of these indices show low banking sector concentration but a rise in the observed period. The values of the comprehensive industrial concentration index and the entropy coefficient confirm the concentration absence in the banking sector of the Republic of Serbia. In addition to the usual banking sector concentration measures, the authors use the Linda index to assess the banking sector concentration and competitiveness, to show the absence of an oligopolistic structure in terms of total balance sheet assets, lending and deposit activity of banks.
#MakeSwedenGreatAgain: Media events as politics in the deterritorialised nationalism debate
Authors: Robinson Jessica Yarin , Enli Gunn 
Published: May 2022

Abstract
Online networks have blurred the lines between national and global news, and have given users a more active role in how information flows. This opens up the opportunity for individuals to engage with foreign events in new ways, curating information and offering their own interpretations. In this article, we investigate how national elections are taken up in the global Twittersphere, using a set of 198,635 English-language tweets about the 2018 Swedish parliamentary election. Based on a network analysis and a content analysis of themes in the tweets, we demonstrate that national media events can become “deterritorialised” by globally networked publics. A second key finding is that the Swedish election is leveraged to discuss anti-globalist themes such as immigration and nationalism in, paradoxically, a global and deterritorialised context.
‘According to Right Law’: John Jewel’s Use of theIus Antiquain His Defense of the Elizabethan Church
Authors: Gazal André A. 
Published: May 2022

AbstractIn hisApology of the Church of Englandas well as many of his other works, John Jewel defended the orthodoxy of the Elizabethan Church on the basis of the following criteria: Scripture, the first four general councils, the writings of the Church Fathers, and the example of the primitive church.1By emphasizing these authorities, the bishop of Salisbury also sought to impeach the Roman Church’s claim to orthodoxy by arguing that doctrines and practices which developed subsequently to the early church as defined by these criteria contradict them, thereby nullifying its charge of heresy against Protestants while simultaneously indicting the papacy itself as heretical. A question that emerges from studying Jewel’s prodigious polemical works concerns the source of this means of determining orthodoxy. Answering this question requires a close analysis of the apologist’s use of sources. This article will attempt to answer this question by arguing that this criteria for defining orthodoxy derived mainly from canon law tradition that is confirmed specifically by Gratian’sDecretum. This thesis maintains that Jewel’s criteria constituted a form of theius antiquawith which he attacked theius novumthat provided the authoritative basis for papal supremacy, and in so doing, sought to vindicate the Elizabethan Church’s place in ancient catholic tradition.
