Published: November 2022

How a person processes, stores or uses information to respond to a task or respond to various types of situations from their environment, is called the cognitive style. Cognitive style is one of the factors that affect students' mathematical problem-solving abilities. This study aims to describe students' mathematical problem-solving abilities in terms of reflective and impulsive cognitive styles on the material of a two-variable system of linear equations. This research is qualitative descriptive research conducted in Kp. Babakan. The instruments used are Test, Interview, Observation, and Documentation, with a population of eighth-grade students as many as 8 students. The sample selection in this study was based on the Matching Familiar Figure Test (MFFT) cognitive style test instrument, then a mathematical problem-solving ability test, interviews, and observations. The results of this study indicate that students' mathematical problem-solving abilities are based on a reflective style. Students have mdkkl indicators of mathematical problem-solving ability. However, there are still a few errors in interpreting the results according to the original problem, while students' mathematical problem-solving abilities are based on an impulsive style. Bagaimana cara seseorang memproses, menyimpan maupun menggunakan informasi untuk menanggapi suatu tugas atau menanggapi berbagai jenis situasi dari lingkungannya, disebut dengan gaya kognitif. Gaya kognitif merupakan salah satu faktor yang mempengaruhi kemampuan pemecahan masalah matematis siswa. Penelitian ini bertujuan untuk mendeskripsikan kemampuan pemecahan masalah matematis siswa ditinjau dari gaya kognitif reflektif dan impulsif pada materi sistem persamaan linear dua variabel.

BACKGROUND: Liver transplantation is a life-saving treatment in end-stage liver failure. Hemorheological features as blood fluidity and red blood cell aggregation may alter effective tissue perfusion, graft function and hemodynamic variables. OBJECTIVE: The aim of the study is to investigate effect of albumin infusion on red blood cell deformability and aggregation, blood viscosity and hemodynamics in liver transplant patients. METHODS: Seventeen live or cadaveric donors were included in this prospective study. Hemorheological and hemodynamic measurements were performed in order to evaluate the effects of albumin infusion in perioperative period. RESULTS: Erythrocyte aggregation was significantly reduced 90 minutes after albumin infusion (p < 0.01). Mean blood viscosity revealed significant decrease at 20 rpm and 50 rpm after 90 minutes of albumin infusion (p < 0.05). Plasma viscosity decreased significantly compared to the value before albumin infusion at 20 rpm (p < 0.05). Albumin replacement improved hemodynamic variables in patients with low blood pressure and cardiac index measurements (p > 0.05). CONCLUSIONS: Human albumin infusion led to decrease in whole blood and plasma viscosities, red blood cell aggregation and induced blood pressure and cardiac index elevation in perioperative liver transplant patients. Determination of hemodynamic and hemorheological effects of human albumin replacement in various patient populations may serve beneficial clinical data.

Authors: Qamar Faisal , Soomro Shuaib Ahmed
Published: November 2022

OBJECTIVE: Drawing on Edgar Schein’s cultural model and the social identity theory, this study attempts to establish an empirical relationship between organizational culture and employer brand with mediation of organizational trust and moderation of employer social media branding. METHODS: The study, being quantitative in nature, used survey method to collect data from 106 employees of public sector universities of Pakistan. A conceptual framework was developed where we tested direct relationship between culture and brand using linear regression. The mediating role of trust and moderation of social media branding were tested with Jamovi statistics. RESULTS: The results suggest that organizational culture has a significant positive relationship with employer brand. Moreover, organizational trust mediates this relationship and employer social media branding emerged as a moderator. CONCLUSION: The study has multidimensional theoretical and practical contributions. It recommends that organizations should use multi-layered culture as an essential tool to develop and improve their employer brand, which can prove a source of attracting quality talent in the modern talent intensive market. This way, organizations can prove themselves as the best places to work. Further, organizations can strengthen their employer brand by improving the trust level between management and employees, and they can harness the matchless power of modern social media for their employer branding activities.
On the use of D2.B10-Dmdmdx/J (D2.mdx) Versus C57BL/10ScSn-Dmdmdx/J (mdx) Mouse Models for Preclinical Studies on Duchenne Muscular Dystrophy: A Cautionary Note from Members of the TREAT-NMD Advisory Committee on Therapeutics
Authors: Aartsma-Rus Annemieke , van Putten Maaike , Mantuano Paola , De Luca Annamaria
Published: November 2022

The C57BL/10ScSn- Dmd mdx/J ( mdx) mouse model has been used by researchers for decades as a model to study pathology of and develop therapies for Duchenne muscular dystrophy. However, the model is relatively mildly affected compared to the human situation. Recently, the D2.B10- Dmd mdx/J (D2. mdx) mouse model was suggested as a more severely affected and therefore better alternative. While the pathology of this model is indeed more pronounced early in life, it is not progressive, and increasing evidence suggest that it actually partially resolves with age. As such, caution is needed when using this model. However, as preclinical experts of the TREAT-NMD advisory committee for therapeutics (TACT), we frequently encounter study designs that underestimate this caveat. We here provide context for how to best use the two models for preclinical studies at the current stage of knowledge.

Authors: Schootemeijer Sabine , Darweesh Sirwan K.L. , de Vries Nienke M.
Published: November 2022

Converging lines of evidence suggest that aerobic exercise impacts Parkinson’s disease (PD) motor symptoms and might slow it’s progression. We provide an overview of the ongoing randomized clinical trials (RCTs) on aerobic exercise in PD. We found six RCTs with sample sizes between 28 and 370 and a follow-up between 8 weeks and 18 months. PD motor symptoms is mostly used as primary outcome while various secondary outcomes are reported. We need more trials that use both clinical endpoints and markers of neuroplasticity, and provide insight into the optimal exercise mode, duration and intensity.

An Exploratory Study on the Accountability of South Korean NGO's Humanitarian Assistance and Development Cooperation Activities on North Korea
Authors:   Korea Association of International Development and Cooperation, Shin Jaeeun , Jung Somin
Published: November 2022

Purpose: This study aims to confirm the recognition of the accountability of humanitarian aid and development cooperation activities of South Korean NGOs on North Korea.
Originality: It is significant in that it attempted a study to confirm the awareness of the accountability of South Korean NGOs even when academic discussions about it were not active and humanitarian activities to North Korea were significantly reduced.
Methodology: It applied the results of Shin (2021)'s research on the accountability components of Korean development NGOs operating in a similar environment of South Korean NGOs on North Korea. It conducted in-depth interviews with the directors of ‘Korean Sharing Movement’, ‘Okedongmu children in Korea’, ‘Korea Ngo Council for Cooperation with North Korea’, ‘Good neighbors’.
Result: As a result, it was found that it is desirable to partially modify and apply the components of the accountability framework of the Korean Development NGO.
Conclusions and Implication: It is necessary to include peace as the ultimate purpose of accountability, and to include the public as the subject of accountability. In addition, it recommends not to utilize the accountability framework functionally only. Accountability is a changing concept according to times, subject of obligation, performance, and short/long-term time perspective, so it is necessary to clarify its meaning when applying the accountability framework presented as a result of this study. In addition, it is necessary to consider the differences in capacity of organization, influence on not only individual organizations but also South Korean NGO groups, and the dilemma of accountability for various subjects.

As the most common congenital heart malformation, tetralogy of Fallot (TOF) produces cyanosis. Patients with TOF suffer from a higher frequency of major noncardiac congenital disorders. Its association with congenital scoliosis influences vital and functional overcomes, restricting physical activity and lowering life expectancy. An 8-month-old female child was reported with admitted cough, fever, and ruled-out pneumonia. The child was diagnosed with heart disease at 2-month-old when cyanosis was apparent. After being admitted to a hospital, history and physical examination showed mild neurodevelopmental delays, such as an inability in rolling and crawling. Her chest x-rays revealed congenital spine abnormalities thoracic vertebral at T3-T8 levels and bilateral segmented-bar sacral vertebrae. Given that patients with TOF routinely undergo chest radiographs, physicians examining TOF patients’ chest radiographs should be aware of the potential for congenital scoliosis to provide early diagnosis and referral for orthopedic evaluation and treatment.
“No Intentions of Such Corrupt Minds Can in the Least Bit Succeed”: Russian Authorities and French Teachers in 1795
Authors:   Institute of World History of the Russian Academy of Sciences, Kosheleva Olga ,   German Historical Institute in Moscow, Rjeutskij Vladislav
Published: November 2022

The article investigates an archival file concerning a project submitted by French teachers to the Director of Elementary Schools in Moscow Guberniia in 1795. The project’s authors aimed at creating a trade union and a platform for legally authorized socializing and mutual aid. Fourteen individuals signed the project, about whom the archival file contains brief dossiers from the Secret Investigation Office (the administrative body in charge of domestic intelligence). The teachers’ initiative gave rise to correspondence between the Governor of Moscow and the Prosecutor General, as well as a direct personal appeal of the latter to the empress. All in all, the documents show the circumspect attitude of the Russian authorities toward the French community in Russia in the time of the French Revolution. The authors analyze this particular episode in the context of the history of the French community, and especially of French teachers, in eighteenth century Russia. The text of the Project for the Union of Teachers is published in the appendix.

What Is Dead May Never Die? Suicides and Buried Alive in the Criminal Courts of Medieval France
Authors:   Institute of World History of the Russian Academy of Sciences, Togoeva Olga
Published: November 2022

The article analyzes the features of the French criminal procedure of the 13th – 15th centuries concerning suicide trials and the practice of burying murderers alive with the bodies of their victims. Drawing on normative documents and sources from judicial practice, the author comes to the conclusion that these legal customs were two sides of the same coin. The perception of the criminal as a dead person at the very time of his sentencing allowed his judges to include both people who (from our point of view) were still alive and their dead bodies in the same category which encompassed those who violated the law and thus made themselves dead.
Managing the Sudden Death of a Handsome Clergyman: the Case of Archimandrite Grigorios Vegleris
Authors:   Southern Connecticut State University, Chrissidis Nikolaos
Published: November 2022

On March 13, 1866 Archimandrite Grigorios Vegleris died in Constantinople. Vegleris was the chief priest of the Holy Trinity Church, the main Greek church in Odessa. His death appeared sudden and unexpected to many observers both in and outside Odessa. It was no coincidence, therefore, that rumors swirled around the circumstances that led to the demise of a popular (by all appearances) archimandrite. Was he poisoned? Was he beaten to near death by one of the most prominent Greek merchants of Odessa and his accomplices? Did he die of some chronic disease? The essay investigates the ways in which the Greek community of Odessa handled Vegleris’s death with the help of local state authorities. It also explores the ways in which death was instrumentalized by Vegleris’s family to promote the career options of their other offspring.
Students and Masters in Portugal between the Late 13th and the Late 15th Centuries: Forms of Representation and Struggle for Legal Status
Authors:   Higher School of Economics, Rusanov Alexandr
Published: November 2022

Universities are traditionally regarded as one of the unique creations of the Latin Middle Ages. Medieval intellectuals, who were closely associated with these institutions, are described (for example, in the works by J. Le Goff) as a new social group that had a huge impact on the history of the West. However, a crucial and hitherto unanswered question is how the novelty of this group was perceived within the framework of the languages of self-description used by medieval society (incl. rhetoric and law). Though a number of studies have been published in this field, they mostly cover only the largest scholastic centers of Europe, particularly Paris. Peripheral universities and members of their corporations, who often replicated the legal models and self-representation rhetoric of famous universities, are not well studied.
The article considers one of such cases – the formation of the social group of Portuguese intellectuals associated with the university community in the 13th–15th centuries. The Portuguese studium generale was founded between 1288 and 1290 in Lisbon and moved repeatedly from Lisbon to Coimbra and back over the next 100 years. During the 13th–15th centuries, ideas of the university community’s role in society changed a lot. Based on an analysis of the terms used in source texts and forms of intellectuals’ representation, the article outlines ways to comprehend the novelty and ‘antiquity’ of medieval university corporations and social groups associated with them.
The Retinue Plays The King: Peculiarities of Impostors’ Communication With Society
Authors:   Institute of World History of the Russian Academy of Sciences, Gerstein Anna
Published: November 2022

The article examines the importance of the retinue in representing a medieval self-appointed ruler’s power. The paper shows this group of people to be the main link in the symbolic, epistolary and ceremonial communication between the impostor and his subjects. Using the examples of impostors who pretended to be Frederick II Hohenstaufen in Sicily and in Germany during the second half of the 13th century, the author finds out what public everyday royal practices were reenacted by the impostors’ assistants to make various social groups believe they were the real monarchs. These practices included sending fake letters on behalf of Frederick II, imitating activities of the imperial curia, and the ceremony of entering the city. In the course of the study, the author arrives at a conclusion that the (re)constructed representations of power were closely associated with memories of emperor Frederick II that the 1260-1280s generation still kept. The impostor's retinue made a point of imitating the modus imperandi of the last Hohenstaufen emperor, actualizing the most vivid and typical images of his power performance.
"The Community of Aureate Equites": the Early Data about the Order of the Garter in Russia
Authors:   Institute of World History of the Russian Academy of Sciences, Boldyreva Natalia
Published: November 2022

The article presents an analysis of early information received in Russia in the 16th-17th centuries about one of the oldest and most honorable knight orders in Europe – the English Order of the Garter. Besides the reports from Muscovite ambassadors to London, one more detailed Russian account of this order has survived. Written by the English antiquarian W. Camden, this text was included in the fourth volume of the most famous geographical atlas of the world – Willem Blaeu’s Atlas Novus. This volume was translated very accurately into Church Slavonic by Isaiah, the Ukrainian-born scribe of the Moscow Chudov Monastery, in the 1650s-1661 at the behest of Patriarch Nikon.
In addition to a detailed description of the appearance of the Knights of the Garter and a description of the brotherhood’s symbol itself, the translation recites legends about the founding of the order. The key point is that the translator interprets the term order to mean a social group rather than an award. This information appears to be very important in the general context of the Russian order system development, since knowledge of the English Order of the Garter and its statutes became one of the starting points for Peter I when planning the introduction of the first Russian order, the Order of St. Andrew the First-Called.

A FOUR-TIER DIAGNOSTIC TEST TO DETERMINE PRE-SERVICE SCIENCE TEACHERS’ MISCONCEPTION ABOUT GLOBAL WARMING
Authors: Atmaca Aksoy Ayşe Ceren , Erten Sinan
Published: November 2022

Global warming is the most serious problem of our age. The most permanent measure to be taken against this problem is to ensure that individuals receive an effective and well-equipped education, free from misconceptions, which are obstacles to the efficiency of education. In this study, it is aimed to develop a four-stage diagnostic test that can reveal the misconceptions of pre-service science teachers about global warming. The sample of the study, in which the survey approach was used, consists of 401 pre-service teachers studying in the science teaching department at different universities in Turkey. The results show that the test is a valid and reliable measurement tool that can be used to determine the misconceptions, scientific knowledge, and lack of knowledge about global warming. In the study, the factor with the highest percentage of pre-service science teachers’ scientific knowledge and misconceptions was the consequences of global warming, while the factor with the highest percentage of lack of knowledge was calculated as the greenhouse effect factor. It is recommended to use the test to determine the current situation regarding the level and areas where the misconceptions of individuals are concentrated to improve the missing or faulty areas in the science curriculum.

DIFFERENCES IN CHEMISTRY TEACHERS’ ACCEPTANCE OF EDUCATIONAL SOFTWARE ACCORDING TO THEIR USER TYPE: AN APPLICATION OF EXTENDED UTAUT MODEL
Authors: Chroustová Kateřina , Šorgo Andrej , Bílek Martin , Rusek Martin
Published: November 2022

In this research, a model to determine chemistry teachers’ acceptance of educational software in secondary education is proposed. The model extends the unified theory of acceptance and use of technology (UTAUT) model. Data were collected from 556 Czech chemistry teachers and analysed using structural equation modelling. With respect to the significant differences among technology users and various types of nonusers, the research model for each user group was tested too. The results showed significant differences in the individual models for each group of technology user. In the model for ‘current users’ of educational software, the influence of facilitating conditions on current users’ use of educational software behavioural intention is stressed. In addition, non-planning users’ behavioural intention seems to be influenced by their personal innovativeness in IT, social influence, and performance expectancy. Behavioural intention and attitude towards using educational software affect each of the tested models, with attitudes being an even stronger predictor of educational software usage than behavioural intention. The models contribute to the understanding of teachers’ acceptance of educational software, which can be utilized in both pre- and in-service teacher training, considering technology mastery a necessary teacher competence. Keywords: chemistry teachers’ motivation, educational software use, secondary education, technology acceptance
EFFECTS OF INQUIRY LEARNING WITH DIFFERENT TASK ORDERS ON FIFTH GRADERS' INDIVIDUAL AND SITUATIONAL INTEREST AND CONCEPT ACHIEVEMENT IN SCIENCE EDUCATION
Authors: Liu Yinsheng , He Wei , Zhao Li
Published: November 2022

Inquiry-based learning has been widely applied in the classroom. Different inquiry learning models may have different orders of performing tasks and discussing. In this study, the Discuss-Do (D-DO) inquiry model and the Do-Discuss (DO-D) inquiry model were applied in the science learning of two groups of fifth-grade students. Group 1 (n = 41) used the Discuss-Do model whereas Group 2 (n = 38) used the Do-Discuss model. Interest measurements and the Light Reflection Test were administered to the two groups prior to and following the experiment to investigate the effects of the two kinds of inquiry model on students' individual and situational interest, and concept achievement through learning the unit of Light Reflection in a science course. Results showed a significant difference in situational interest and concept achievement between the two groups. However, there was no significant difference in the individual interest of the two groups. Findings suggested that the adoption of the Do-Discuss model is more conducive to learners' development of situational interest and concept achievement, which has implications for exploring task order adjustments for inquiry-based learning, as well as in education for science instructors.

Materials and methods: This observational study was carried out in the department of Obstetrics and Gynecology of Bangabandhu Memorial Hospital, Chattogram, during the period January to June, 2013. Total 168 pregnant women who were at term and expected to have a vaginal delivery were taken for this study. Results: The median length of the 3rd stage of labour was 8.8 minutes. 11 women (6.54%) required a manual removal of the placenta and 23 patients (13.69%) needed further therapeutic oxytocin to control bleeding. In 145 cases (86.30%) additional oxytocic was not required, about 93.45% cases placenta was expelled out easily by active management of 3rd stage. There was a drop in Hb and haematocrit concentration after delivery, which was statistically significant. An upward trend was (>0.11°F) noticed regarding temperature after delivery. Conclusion: Misoprostol is effective for prevention and management of postpartum haemorrhage, & can consider as a good alternative to other conventional oxytocic drugs.

Published: November 2022

Background: Fine Needle Aspiration Cytology (FNAC) has been widely accepted as an accurate and minimally invasive diagnostic procedure in the investigations of salivary gland masses. The aim of this study was to determine the accuracy of FNAC in the diagnosis of pleomorphic adenoma. Materials and methods: A cross sectional comparative study was carried out on a total of 28 patients with salivary gland swellings who underwent preoperative FNA examination. After surgical excision of tumours, all FNAC findings were subsequently verified with histopathological examination. All the necessary and relevant data were recorded methodically and meticulously and statistical analysis was done by computer software device (SPSS-18 version). Results: On preoperative FNA examination, among the 28 cases, 19 (67.9%) cases were pleomorphic adenomas. On histopathological examination, out of 28 cases, 20 (71.4%) cases were pleomorphic adenomas. Out of 19 cases of pleomorphic adenomas diagnosed by cytology, 17 cases were confirmed by histopathology. Remaining two cases revealed different diagnosis. In three cases of pleomorphic adenomas diagnosed by histopathology, the cytology revealed different diagnosis. In six cases of tumours other than pleomorphic adenoma there was agreement between cytological and histological diagnosis. The diagnostic sensitivity, specificity and accuracy of preoperative FNAC of pleomor phic adenoma were 85%, 75% and 82.1% respectively. The Positive Predictive Value (PPV) and Negative Predictive Value (NPV) of FNAC were 89.5% and 66.7% respectively. Conclusion: Fine needle aspiration cytology is a useful preoperative diagnostic tool in evaluating Pleomorphic adenoma of salivary gland.

Published: November 2022

Background: Heated humidified high-flow nasal cannula (HFNC) has gained popularity recently and is considered a standard respiratory support tool for pediatric patients with acute respiratory distress. However, data are limited on the bedside parameters that can predict HFNC failure in pediatric patients.Purpose: To evaluate the performance of SpO2/FiO2 (SF) ratio, pediatric respiratory rate-oxygenation (pROX) index, and clinical respiratory score (CRS), for predicting the HFNC outcomes.Methods: This prospective observational study included 1- month to 15-year-old patients with acute respiratory distress who required HFNC support. The HFNC setting, vital signs, CRS, and treatment outcomes were recorded. Data were analyzed to determine the predictors of HFNC failure.Results: Eighty-two children participated in the study, 16 of whom (19.5%) did not respond to HFNC treatment (failure group). Pneumonia was the main reason for intubation (62.5%). Predictors of HFNC failure at 12 hours were: SF index ≤166 (sensitivity, 62.5%; specificity, 87.8%; area under the curve [AUC], 0.75), pROX index <132 (sensitivity, 68.7%; specificity, 84.8%; AUC, 0.77), and CRS ≥6 (sensitivity, 87.5%; specificity, 96.9%; AUC, 0.92).Conclusion: The CRS was the most accurate predictor of HFNC failure in pediatric patients. A CRS ≥ 6 at 12 hours after HFNC initiation and pROX, a newly modified parameter, are helpful indicators of HFNC failure.

Solar energy is a renewable energy that has not been widely implemented in a mass manner. To optimize the use of a solar panel, usually a control system that can adjust the position of the solar panel automatically is employed to get the optimal power value. This prototype tracking system of solar panels is dynamically following the direction of sunlight. The supporting devices used in this prototype are LDR sensor, Servo, Arduino Uno, Ina219, Bread Boot Power Supply and solar cell which must be activated first to work. The servo will drive a 3D printing device that is connected to an LDR sensor that is sensitive to sunlight. The Ina219 component serves to absorb the intensity of the sun and convert it in terms of voltage (volts) and electric current (amperes). The energy absorbed by the solar panels in the form of voltage and electric current will be stored in the battery so that it can turn on the lights. The solar panel prototype will be placed in an open area to get optimal solar energy compared to static solar panels.

The use of information technology in filing letters has been widely applied, especially in government institutions. In the Administrative Affairs of the Police Information Technology Bureau, the archiving of incoming and outgoing letters is still done manually, by utilizing records in a large agenda book and stored in a large folder. The absence of a system capable of assisting mail processing causes work to be inefficient, especially in terms of searching for letters. The purpose of this research is to produce a website that can help search letters by applying the Levenshtein Distance Algorithm. The design begins with needs analysis, design, implementation, verification (system testing), operation and maintenance. A website that can search letters by applying the Levenshtein Distance Algorithm was generated. This website is very helpful in the process of searching for letters to the Administrative Affairs of the Police Information Technology Bureau.
Proteomic Analysis of Antiprotease Immunoglobulin-E Anti-Sperm Autoantibodies in Chronic Urticaria After Vasectomy
Authors: Dreyfus David H.
Published: November 2022

Some types of chronic urticaria (CU) are associated with autoreactive immunoglobulin (Ig)E, as well as IgG. In the syndrome of autoimmune thyroid disease and CU, autoreactive IgE, as well as IgG against host thyroid tissue, is present. The author describes a patient with new onset of CU after vasectomy with evidence of both autoreactive IgE and IgG anti-sperm antibodies (ASA). Autoreactive sperm proteins are enzymes opposed to structural sperm antigens producing ASA in infertility and after anti-spermatocyte vaccines. The author suggests that autoreactive proteins with enzymatic activity either in host proteins, aeroallergens, or viral proteins may have increased propensity to generate autoreactive IgE. This model of autoimmune IgE ASA generation by sperm and other host enzymatic proteins in CU can be tested using proteomic technology. INTRODUCTION

Published: November 2022

Background: Herpes simplex labialis is a common skin condition caused by the herpes simplex virus. The prescription of antivirals for the treatment of herpes labialis is common. The objective of this study was to conduct a systematic review of the available evidence on the treatment of herpes simplex labialis with U.S. Food and Drug Administration (FDA)-approved topical antibiotics. Methods: The literature search included searches of PubMed, Google Scholar, and Scopus. This review included studies that examined herpes labialis lesions and treatment with topical acyclovir, penciclovir, or docosanol in at least one of the study arms. Results: Of the 1,485 papers initially identified, 20 papers representing 19 randomised controlled trials and one quasi-randomised trial met the inclusion criteria for the systematic review. Conclusion: Our systematic review of the clinical studies performed on the three topical antiherpetics, acyclovir, penciclovir, and docosanol, showed that their efficacy compared to placebo is marginal at best (shortening the duration of pain by <24 hours), although the three topical antiherpetic drugs have no serious adverse reactions and are safe to use.
