THE CONNECTION BETWEEN TRANSCENDENTAL LOGIC AND EGOLOGY: HISTORICAL AND PHILOSOPHICAL ASPECT
Authors:   The State Institute of Economics, Finances, Law and Technologies, Gatchina, Russia, Sedov Yu.G.
Published: July 2021

The article substantiates the need to create a pure egology in order to analyze the structures of consciousness. The relevance of egological research is to form the foundation for disparate cognitive sciences. On the basis of the historical and philosophical approach, the idea of transcendental logic is considered and it is concluded that it is essentially correlated with the analysis of consciousness. Transcendental logic takes into account the pure content of human thinking, which is not reduced to an empirical composition. Results. 1. The question of the dual nature of logic was first raised by the ancient Stoics, who included in it a section devoted to the analysis of impressions and the formulation of criteria for knowledge. 2. The idea of transcendental logic is presented in its expanded form in the works of Kant, who divided it into analytics and dialectics. In the analytical section, Kant is confronted with a paradox — with the division of the pure I into two parts: active subject and passive object. The identity of these parts does not give any knowledge of how the pure I exist in itself. As a result of the transcendental analysis, a distinction is introduced between the pure and the empirical subject. 3. Hegel’s critical reinterpretation of the idea of transcendental logic leads to a new division, in which it corresponds to an objective logic that takes into account the content of knowledge and its origin. 4. The connection between logic and egology was found in Husserl’s later works, most systematically in “Formal and Transcendental Logic”. Transcendental logic is a subjectively oriented study that clarifies the constitutive activity of pure consciousness. The scientific novelty of the research consists in the fact that the pure I as a subject of egology contains and produces objective logical formations. Formal logic is concerned with inference and proof, being a demonstrative rather than descriptive discipline. This lack of formal logic can only be eliminated by transcendental logic, which directly addresses the experience of pure consciousness. It should be used to study the subjective structures that underlie theoretical reason. Thanks to the experience of egology, there is a real opportunity in the future to solve the question of reason in its relevance and live performance, in which objective formations find their source.
The Method of Cyber Awareness Analysis of an Energy Facility
Authors: Gaskova D. A. , Massel A. G.
Published: July 2021

The article proposes to analyze cyber-situational awareness of an energy facility in three stages. There are i) analysis of cyber threats to the energy infrastructure; ii) modeling of extreme situations scenarios in the energy sector caused by the implementation of the cyber threats; iii) risk assessment of the cybersecurity disruption to energy infrastructure. Three methods are presented, corresponding to each stage. The authors propose to apply semantic modeling methods to analyze the impact of cyber threats to energy facilities, taking into account energy security within the presented approach. Such methods show their effectiveness in the absence or incompleteness of data for modeling the behavior of systems, which defies formal description or accurate forecasting. The presented approach to the cyber situational awareness analysis of energy facilities considered as a synthesis of cybersecurity and situational awareness studies, characterized by the use of semantic modeling methods.
Web Platform for Folklore Research Based on Domain Ontology
Authors: Lisin V. A. , Sidorova E. A.
Published: July 2021

In this paper, we take a close look at a web platform that provides the tools necessary for working with folklore materials and conducting scientific research based on them. Folklore studies consist of working with audio and video materials, which contain the reproduction of elements of folk art in national languages, creating specific text recordings with translation and comments, written in a public language, and building a picture of the worlds based on available resources. To structure and present this content, we use an ontology-based approach, which allows linguists to describe not only the resources, but also subject knowledge in the Semantic Web style, i.e. using hierarchies of classes, objects and relationships between them. The main feature of folklore research is the need for synchronization of translations, which is achieved by creating a parallel corpora of texts, and the ability to label texts with entities of the subject area, which is called semantic markup. Moreover, each corpus is connected with a certain nationality and has both its own national language and unique system of concepts of the world around it. Such representation imposes many non-standard requirements for the platform, such as working with arbitrary languages, supporting many ontologies, ensuring the creation and editing of national subject ontologies, semantic text markup, presentation, navigation, and search across heterogeneous resources. The developed platform provides all the necessary tools for research, including tools for the development of ontologies in specific national subject areas and manual annotation of texts in real time by several specialists. Resources of the web-platform are located in the resource ontology, which includes such concepts as corpus, video resource, audio resource, graphic image, person, geographical location, genre of text, etc. Ontologies of subject areas are presented in the form of a hierarchy, where the ontology of universals, common to all folklore studies, is located at the top level. At the same time, inherited ontologies are specialized for each represented national corpus. The web application is built with Python Django framework and the TypeScript React library. Data storage is implemented using the Postgres database.
Automatic Linking of Terms from Scientific Texts with Knowledge Base Entities
Authors: Mezentseva A. A. , Bruches E. P. , Batura T. V.
Published: July 2021

Due to the growth of the number of scientific publications, the tasks related to scientific article processing become more actual. Such texts have a special structure, lexical and semantic content that should be taken into account while processing. Using information from knowledge bases can significantly improve the quality of text processing systems. This paper is dedicated to the entity linking task for scientific articles in Russian, where we consider scientific terms as entities. During our work, we annotated a corpus with scientific texts, where each term was linked with an entity from a knowledge base. Also, we implemented an algorithm for entity linking and evaluated it on the corpus. The algorithm consists of two stages: candidate generation for an input term and ranking this set of candidates to choose the best match. We used string matching of an input term and an entity in a knowledge base to generate a set of candidates. To rank the candidates and choose the most relevant entity for a term, information about the number of links to other entities within the knowledge base and to other sites is used. We analyzed the obtained results and proposed possible ways to improve the quality of the algorithm, for example, using information about the context and a knowledge base structure. The annotated corpus is publicly available and can be useful for other researchers.
Strategic Vectors of Library Development
Authors: Redkina Natalia S.
Published: July 2021

Establishing of library development strategy is the most important stage in solving the tasks of adapting to the changing environment and increasing demand of users. The purpose of this study is to determine the vectors of strategic development of libraries (public libraries and libraries of scientific and educational institutions). Basing on the results of the analysis, the author identifies nine essential strategic directions and ten vectors, revealing the prospects for the development of libraries, being not only the information repositories and library and information centres, but also working, creative spaces, communication platforms, places for renting equipment, startup sites, etc. The article presents the specific features of public libraries, which are close interaction with the local community, promotion of intercultural and intergenerational dialogue, as well as socialization of the population. Strategies of libraries of scientific and educational institutions much attention pay to the integration of librarians in the research process, creation of analytical products, development of services for scientometric analysis and information support for open scientific research. Libraries strive to serve readers and visitors with the use of modern information technologies, organize spatial environment that ensure comfortable stay, provide resources and services that meet the changing preferences of users, which allows creating positive image of the library and attracting readers.
Formation of the Digital Collection “Books of the Imperial House of Romanovs” in the National Electronic Library
Authors: Yemelyanova Elena A.
Published: July 2021

The article is devoted to the creation of the collection “Books of the Imperial House of Romanovs” in the National Electronic Library (NEB) within the framework of the project “Book Monuments”. The general approach to the designation of imperial and grand ducal collections is based on the analysis of presence of the books in the collections of the Russian State Library (RSL). To justify the decision, the author considers the history of private book collections that belonged to the Romanovs before 1917 and their fate after the revolution. The book collections of representatives of the family in historical and scientific literature are divided into imperial and grand ducal collections. After the revolution, the significant part of the libraries located in the residences of St. Petersburg and its suburbs were moved to the Winter Palace. Some collections remained in the owners’ palaces and were distributed and moved to different organizations. After the decision was made to allocate the books to different organizations, the significant part of them was sent first to the Rumyantsev Museum, and then to the V.I. Lenin State Library of the USSR (now the Russian State Library). After registration, the books were distributed between different parts of the holdings without taking into account the ownership of the previous owners; and at present, it is not possible to restore them as a single complex. Based on the study and analysis of the archival documents of the Russian State Library, which had covered the receipt and allocation of the books in quite a detail, it was decided to combine all the books into a single electronic collection, since only this decision will allow getting together the copies of imperial and grand ducal books on a single resource and making them available for general access and study. The NEB’s capabilities allow providing information to specialists in the humanities and a wide range of users.
Risky Profession: How U.S. Librarians Fight for Their Safety
Authors: Neshcheret Marina Y.
Published: July 2021

In society, the concept of public library is traditionally associated with silence, peace and safety. However, modern realities indicate that the library profession is associated with many risks. As the experience of the United States shows, employees of public libraries are increasingly faced with problems that disrupt the normal functioning of library and information services and negatively affect the emotional and psychological state of staff and patrons. Ensuring safety of the library is a common concern, equally affecting both employees and patrons of the library. A threat to the safety of library is a potentially or actually possible event, action, process or phenomenon that can disrupt the stability of its operation or lead to shutdown of its functioning. The article considers the subjective threats, i. e. caused by the actions and behaviour of people. These can be mentally unbalanced, substance abusers or armed visitors, computer hackers, etc. Many of them pose a real danger to life and health of both librarians and library patrons. Based on the analysis of the U.S. periodical press, the author provides facts that clearly demonstrate the vulnerability of public library staff to the threats of the modern world: the risk of being killed, the risk of drug overdose of visitors, the risk of hacker attacks on library computers, the risk of developing post-traumatic stress disorder, etc. Library rules and regulations are created to protect the rights, interests and safety of users and employees. It is necessary to keep them up-to-date taking into account the socio-cultural changes in modern society and transformation of human behaviour. The article shows what measures are taken by U.S. public libraries to ensure the safety of employees and patrons.

Digitale Lehre und Prüfung im Grundlagenfach Maschinenelemente
Authors: Rosenlöcher Thomas , Schlecht Berthold
Published: July 2021

In Vorlesungen, Übungen und auch Praktika steht neben der Vermittlung von Wissen mit Hilfe von Tafelbildern, Folien und Präsentationen das kontinuierliche Einholen einer Rückmeldung von den Studierenden im Mittelpunkt, über die man als Lehrender bewerten kann, inwieweit die Ausführungen durch die Zuhörer auch verstanden wurden. Im Seminarraum ist dies ohne Einschränkungen möglich. Bei großen Vorlesungen können in den meisten Fällen nur die ersten Reihen für ein solches Feedback einbezogen werden. In drei Semestern der Lehre über verschiedene digitale Wege musste schlagartig akzeptiert werden, dass eine Rückmeldung zu den Lehrveranstaltungen nicht direkt und zumeist erst mit Evaluationen am Ende des Semesters durch die Studierenden gegeben werden. Die Überführung bewährter Lernkonzepte in einen Lehrbetrieb ohne Präsenzunterricht unter den ungünstigen zeitlichen wie auch technischen Randbedingungen erforderte enorme Anstrengungen, erwies sich jedoch auch als eine wirksame Antriebskraft, die Art und Weise zu Lehren und die Bedürfnisse der Studierenden aus einem anderen Blickwinkel zu sehen.

Published: July 2021

Computerpraktika stellen einen wichtigen Bestandteil vieler Lehrveranstaltungen dar, welche die Grundlagen und Details von computergestützten Methoden vermitteln sollen. In den Materialwissenschaften spielen solche Methoden eine zunehmend wichtige Rolle. Typischerweise setzen die Praktika eine physische Präsenz in den PC Pools voraus, u.a. da eine Vielzahl von verschiedenen Programmen lokal installiert und bereitgestellt werden muss. Um Computerpraktika auch in der Online-Lehre vollumfänglich und weitestgehend unabhängig von den Gegebenheiten der Studierenden einsetzen zu können, wurde im Wintersemester 2020/21 ein virtueller PC Pool auf Basis von virtuellen Maschinen mit Web-basiertem Zugang eingerichtet. Dieser virtuelle PC Pool wurde in verschiedenen Lehrveranstaltungen erfolgreich eingesetzt und kann auch bei hybriden Lehrformaten in verschiedenen Disziplinen verwendet werden.
Möglichkeiten von OpalExam zur Verbesserung von Klausurbewertung und -einsicht
Authors: Fiedler Melanie , Kästner Markus
Published: July 2021

Durch die Umstellung von Präsenz- auf Onlineklausuren stehen Lehrende vor neuen Herausforderungen. Dabei geht es nicht alleine nur um die technische Herausforderung, sondern auch um den eigenen Anspruch, Klausuren online so zu modellieren, dass Betrugsversuche entweder verhindert werden können oder dem Betrügenden keine Vor- sondern Nachteile bieten. Lehrenden stehen dabei während der Klausurmodellierung in OpalExam verschiedene Möglichkeiten zur Verfügung: Definition von Zufallswerten durch Verwendung von Variablen in der Aufgabenstellung, Erstellung mehrerer Varianten einer Aufgabe, die den Studierenden zufällig zugewiesen werden oder auch Änderung der Aufgabenreihenfolge für die Studierenden und Definition eines linearen Durchlaufs durch die Klausur. Die einzelnen Optionen können dabei natürlich auch kombiniert werden.
Wird ein nichtlinearer Verlauf (Studierende können zwischen den Aufgaben beliebig hin- und herspringen) durch die Klausur angestrebt, so werden die Klausuren durch die Wahl der ersten beiden Optionen komplexer. Für Studierende wird dadurch zwar die Zusammenarbeit erschwert, die Bewertung der Antworten des Studierenden durch den Prüfenden allerdings auch. Innerhalb dieses Aufsatzes werden deshalb Möglichkeiten aufgezeigt, wie der Bewertungsaufwand gesenkt und dabei gleichzeitig die Klausureinsicht erleichtert werden kann.

Nikolai Sverchkov as an artist-animal painter, genre painter and portraitist (1817-1898)
Authors: Филиппова О.Н.
Published: July 2021

Николай Егорович (Георгиевич) Сверчков (1817 – 1898) – один из ранних представителей реалистической жанровой живописи. В своих картинах он запечатлел природу России, с ее величественными лесами и необъятными полями, бесконечными дорогами и проселками. Н.Е. Сверчков впервые в русском искусстве развил мотив удалой «птицы-тройки», с образом которой народ связывал свои мечты о лучшей, свободной жизни. Творчество художника многообразно. Он писал не только жанровые, но и исторические и батальные полотна, занимался скульптурой. Редкого мастерства Н.Е. Сверчков достиг в изображении животных, особенно лошадей. Его дорожные сцены, картины охоты, конные портреты сыграли видную роль в истории русской живописи.

Nikolai Yegorovich (Georgievich) Sverchkov (1817-1898) was one of the early representatives of the realist genre painting. In his paintings he captured the nature of Russia, with its majestic forests and vast fields, endless roads and country roads. N.E. Sverchkov for the first time in Russian art has developed the motif of daring "bird-Troika", with the image which the people placed their dreams of a better, free life. The artist's work in many ways. He did not write both genre and historical and battle paintings, studied sculpture. Rare skill N.E. Sverchkov have achieved in the depiction of animals, especially horses. His travel scenes, hunting paintings, horse portraits played a prominent role in the history of Russian painting.

Best practices for supporting student experiential learning in an online environment during emergency situations
Authors: Munro Deborah , Clarke Jenny
Published: July 2021

Background: In 2020, nearly four weeks into the first semester of the academic year, the University of Canterbury (UC) in Christchurch, New Zealand, transitioned to online delivery of all teaching in response to the nation-wide lockdown due to Covid-19. With 48 hours’ notice, all on-campus activities ceased and were replaced with lectures delivered live via Zoom or recycled from previous delivery, and simulated, or otherwise facilitated, practical experiences. Assessments were temporarily halted, then resumed over a more compressed timetable with online and “take home” activities largely replacing traditional invigilated assessments. Purpose: Our research explored the challenges and successes of UC’s fast transition to online learning, with a particular emphasis on understanding the impact of the loss of face-to-face delivery on practical experiences normally delivered through laboratory and field activities. Our goal was to develop a set of best practices to improve our response to future emergency situations. Methods: A two-part survey was electronically distributed to students enrolled in a 4-year engineering programme and a 3-year sport coaching programme at the University of Canterbury. Results: While students strongly appreciated efforts of lecturers and tutors to support their learning, differences in communication approaches affected student experience both positively and negatively. A clear need for two-way communication as well as consistency and clarity in messaging were key findings. A general dissatisfaction with replacement practical activities was expressed, demonstrating a need for contingency measures to be in place to mitigate the impact of future disruptive events on practical learning. Efforts to manage online assessment of learning were generally well received, even in a compressed timeframe, though several unhelpful practices were highlighted. Students also identified many positive aspects of their learning experiences, including live tutorials and made-for-purpose video presentations.
Does acculturation influence immigrants’ level of environmental engagement? The case of Vietnamese in New Zealand
Authors:   , Nguyen Tram
Published: July 2021

Within the current global context, research on human-environment interaction has extended its scope to examine environmental concern and pro-environmental behaviours across cultures. Although few studies have considered acculturation as a determinant of environmental concerns, attitudes, and pro-environmental behaviours, its role in human-environment interaction remains unanswered. We conducted two studies to examine the role of acculturation for environmentalism in Vietnamese immigrants living in New Zealand. Since the New Zealand context is better regarding environmental quality and practices when compared to Vietnam, we predicted Vietnamese living in New Zealand would show greater pro-environmental concern and behaviours than Vietnamese in Vietnam due to their acculturation to the newer environmentalism -prone context. In Study 1, we tested our hypotheses by conducting an online survey with Vietnamese living in New Zealand (N = 114) and a propensity matching sample of Vietnamese living in Vietnam (N = 114). Rejecting our predictions, results indicated no differences in environmental concern and pro-environmental behaviours between Vietnamese in New Zealand and those in Vietnam. Partially supporting our predictions, however, regression results indicated that acculturation orientation towards New Zealand positively correlates with pro-environmental behaviours, but not with environmental concern. In Study 2 (N = 12), we conducted four focus groups with Vietnamese living in New Zealand to gather information about their acculturation experiences regarding environmentalism, and data were analysed thematically. We found that most participants have perceived influences of living in New Zealand on their pro-environmental behaviours and believe these acculturation influences would not last long if they went back to live in Vietnam. Findings indicate that context matters when examining human-environment interaction, but the effect of acculturation still needs further examination.
All Things to All Men: Ethos in Cicero’s Post-Ides Correspondence
Authors:   , Galloway Meg
Published: July 2021

In the wake of Caesar’s assassination, Cicero was without the necessary magisterial and martial authority to direct affairs and his influence over the fractious Senate was fragile at best. So, too, did he face the challenge of physical distance. With influential statesmen scattered across the Roman world, the reliance on correspondence for political manoeuvring and the performance of self was more pronounced than ever before. Cicero’s letters, then, played an essential role in his self-fashioning of authority after the Ides of March.

This thesis illuminates the nuanced, critical, and underappreciated role that Cicero’s correspondence played in his cultivation of fresh influence after Caesar’s death by assessing the post-Ides corpus through the lens of ethos. In particular, Aristotle’s conception of ethos as comprising phronesis (‘practical wisdom’ or ‘prudence’), eunoia (‘goodwill’ or ‘benevolence’), and aretē excellence’ or ‘moral virtue’) provides a valuable framework. When applied to the letters, three distinct instances of epistolary persona creation are revealed: Cicero as Nestor, Cicero as amicus, and Cicero as saviour. Each of these personae, it is demonstrated, are ultimately employed by the statesman to establish authority as the res publica’s helmsman.

US COVID-19 EXAM FAILURE MAKES WORLD LEERY ABOUT AMERICAN EXCEPTIONALISM AND LEADERSHIP
Authors: Popa-Simil Liviu
Published: July 2021

For a newbie in the USA, heath care, education, science and economy are presented as exceptional; the best of the world, but these nice words are not backed by reality, and it is hard to openly talk about these issues as they turn into an inconvenient truth, and the fact that truth is anti-American and anti-human makes it more difficult to correct the problems, as it turns difficult to openly acknowledge the issues and look for solutions. Trump and revealed a bunch of American truths, removed the of kindness and exceptionalism, and put in the limelight a lot of inconvenient realities of the actual USA, a country ideologically divided and under Lord , a nation sunk in alternate realities and facts, with a political leadership inept for progress. Looking to understand why this aberrant behavior in front of SARS-CoV-2 pandemic, we discovered that the F++ grade USA obtained at this “ecologic” exam, is routed in education of the last 50 years, that produced such population with very low real IQ, but loud arrogant and oblivious of their situation, with little respect for reality and knowledge.

From the education stand point, the thinks appear even more complicated, because failures in education are routed in society, and the education system produced exactly what society asked and paid for, everything becoming a “chicken or egg” problem, under “what to solve first” dilemma

The present research was looking to find an answer to this very complex problem, at minimum to openly list the issues, and propose idealistic solutions, looking to become a wake-up moment not only for the USA but for many other nations which are confronted with the same issues, of a decadent democracy and consumerist economy, without pleading for extreme left solution manifested autocratic regimes.
Protecting persons at-risk of viral hepatitis and alcohol-related liver disease during the pandemic and beyond: mitigating the impact of coronavirus disease 2019 on liver health
Authors: Taye Belaynew W , Valery Patricia C , Clark Paul J
Published: July 2021

Background

Treatment seeking for people with alcohol use disorders (AUD), injecting drug use and viral hepatitis is low, and has worsened during the coronavirus disease 2019 (COVID-19) pandemic. Deferring clinical care and increasing drug and alcohol use exacerbate the risks of progression for individuals with chronic liver disease from viral hepatitis and/or alcohol-related liver disease (ALD). We explored the impact COVID-19 epidemic may have on patients with chronic liver disease and suggested mechanisms to protect this at-risk population during and after the pandemic.

Methods

We searched PubMed, EMBASE, and Google Scholar for published articles and grey literature and synthesized information about the impact COVID-19 has on patients with chronic liver disease, specifically related to impacts and opportunities to prevent viral hepatitis and ALD.

Results

The COVID-19 pandemic has caused significant disruption of clinical management of patients with liver disease, but also to alcohol and drug services, needle and syringe programs (NSP), hepatitis B (HBV) screening, and treatment efforts. Social isolation and pandemic-related anxiety have caused an increase in alcohol and drug use. COVID-19 pandemic disruptions may lead to an increase in the incidence of viral hepatitis and ALD, but also cause patients to undertake risky behaviours. The pandemic impacts people with chronic conditions such as HBV to defer medical visits or undertake screening tests. These factors may worsen rates of decompensation for patients with cirrhosis, for whom these deleterious impacts are believed to stay for some time after the pandemic. Interruption in screening, treatment, and monitoring services during the period disrupts chronic disease management of viral hepatitis and ALD and increases the risk of worsening the clinical course of liver disease and delayed diagnosis of hepatocellular carcinoma.

Conclusions

Successful mitigation of the impact of COVID-19 on the incidence of viral hepatitis and alcoholic liver disease requires adaptive approaches to reach people with injecting drug use and AUD including community-based networks, fixed site and mobile NSP, mail delivery systems, the use of telehealth, and other digital media for promoting and implementing alcohol harm reduction during and after the COVID-19 pandemic.

Authors: Gautam Arun , Dangol Nixon , Bhattarai Urza , Paudel Sandesh , Poudel Bipin , Gautam Shankar , Sharma Prabhat , Uranw Surendra , Sharma Sanjib K
Published: July 2021

Background

There are various COVID-19 vaccines launched in different parts of the world. As the vaccination drive is increasing, the reports of adverse events following immunization (AEFI) are increasingly reported. Therefore, this research aims to document the adverse events and their determinants following COVID-19 vaccination.

Methods

This was a cross-sectional study conducted in a primary healthcare setting of Western Nepal. Those individuals who took the first dose of the ChAdOx1 nCoV-19 vaccine in the health care center (N=425) were eligible for the study. The details to contact the study participants were obtained from the vaccination center. Patients were contacted via phone calls by investigators. Information on demographic details, comorbidities and experiences of any sort of adverse events following vaccination was collected using pre-structured questionnaire. Descriptive statistics was done to describe the categorical variables in frequency and percentage whereas mean, median, standard deviation and interquartile range were calculated for quantitative variables. Binary logistic regression was carried out to explore the potential determinants of AEFI.

Results

A total of 302 (71.05%) people were randomly selected from 425 targeted people for vaccination at the primary health care center. A total of 276 (91.3%) people vaccinated with ChAdOx1 nCoV-19 vaccine responded to telephone call. Mean age of participants was 33.63 (± 11.14) years and majority of them were males (54.74%). 91.6% of participants developed some form of AEFI. Among them, 46.6% developed mild AEFI, and 53.4% developed moderate AEFI. Pain on the injection site, generalized weakness, fever, headache, joint and muscle pain, dizziness, and loss of appetite are found to be the “Very common” adverse events. Females tend to develop moderate AEFI than males (OR 2.369; 95% confidence interval, CI=1.398-4.014; P=0.001). Age did not seem to be the determinant of AEFI (OR 0.977; CI=0.954-1.002; P=0.067).

Conclusions

Adverse events following COVID-19 immunization are common but not severe. The severity of AEFI is more in females compared to males. Age did not come out as a predictor for severity of AEFI. Post-vaccination counseling targeting women will improve the acceptance of the vaccine. We recommend further monitoring of AEFI in larger population.

Several Programme for International Student Assessment (PISA) research articles published in Indonesia have contributed to PISA research development in Indonesia, with mathematics as one of the PISA domains. However, there is no research to categorize the PISA research article to give future PISA researchers essential information. Therefore, this study aims to organize PISA research in Indonesia in the period 2016-2020. This study uses the Systematic Literature Review (SLR). The SLR method identifies, analyzes, evaluates, and categorizes specific topics related to PISA research in Indonesia. The research data comes from 27 articles published in thirteen accredited journals in the Sinta 1 and Sinta 2 category by the Ministry of Research, Technology and Higher Education of the Republic of Indonesia as an achievement for review journals, which have excellent management and publication quality. The findings indicated that nine categories were identified in this study, including the PISA articles dominance, the development of PISA model math problems, PISA research and subjects, the research methods, the content and context, students' abilities, and the level of the questions. Lastly, this research contribution also is intended to guide future PISA researchers in determining PISA research trends and the following PISA research opportunities in Indonesia.

However, reflection and translation material are still difficult for students to understand. Therefore, this study aims to develop a learning trajectory that will assist ninth-grade students of Junior High School in grasping the notion of reflection and translation in the context of the Sam Poo Kong Temple in Semarang. The research used the design research method, which consisted of three stages: the preliminary design, the design experiment (pilot experiment and teaching experiment), and retrospective analysis. The PMRI approach was used to develop learning activities in this research. This study involved 32  ninth-grade students at a junior high school in Semarang city. The results of this study is a learning trajectory that includes a series of learning processes in four activities. These are observing the Sam Poo Kong Semarang video and analyzing the properties of reflection, finding the reflection formula, analyzing the properties of translation, discovering the translation formula, and solving contextual problems related to reflection and translation. The activities conducted can enable students to develop a better understanding of material reflection and translation. The research's findings indicate that using the Sam Poo Kong Semarang temple context can equip ninth-grade students to comprehend the concept of material reflection and translation. Additionally, the outcome of this study offers additional local wisdom options that can be used as a context in mathematics.

The process of thinking in formulating a mathematical model requires cognitive processes. In learning mathematics, one of the factors that influence mathematics ability is gender differences.  This research explores and provides an overview of the cognitive processes, especially using the representational form in mathematical modeling regarding gender differences. The type of research used is descriptive exploratory with a qualitative approach. The research subjects were 36 pre-service teachers in the mathematics education study program, consists of 18 males and 18 females. The instruments were a written test and an interview guide sheet. The result shows that males get higher percentages than females to answer the representational problem correctly. In conclusion, both males and females solve the graph problem using representative form through three components of the cognitive process.  The first and second component, namely knowing and applying, shows the same behavior: retrieving the information from the mathematical problem and displaying the information into the graph. For the third component, reasoning also offers the same behavior because the truth of the graph that justifies refers to the mathematical properties. The study implies that it might be the same treatment for males and females to improve representational form regarding the components of cognitive process, namely, knowing, applying, and reasoning.

Published: July 2021

Turbine intake air cooling (TIAC) by absorption lithium-bromide chillers (ACh) utilizing the exhaust heat is considered as the most effective fuel saving technology for temperate climatic conditions. But the cooling potential of TIAC systems based on ACh of a simple cycle is limited by a comparatively increased chilled water temperature of about 7°C excluding cooling intake air lower than 15°C. The application of a refrigerant as a coolant enables deeper cooling intake air to 10°C and lower. The application of two-stage hybrid absorption-ejector chillers (AECh) with a refrigerant ejector chiller (ECh) as a low temperature stage makes it possible to increase the annual fuel saving approximately twice in temperate climate due to deeper cooling air as compared with ACh. Furthermore, this effect can be achieved with the sizes of TIAC system reduced by about 20 % due to determining the rational refrigeration capacity of AECh providing practically maximum annual fuel saving increment and the use of the current excessive refrigeration capacities to cover peaked loads.
