Published: December 2023

Background The asynchrony rapid phase of cognitive, physical and emotional development occurring in adolescence may result in various issues such as risk-taking behavior, psychosocial and emotional problems. School closure during the COVID-19 pandemic has caused a tremendous change in adolescent lifestyle and habits, including sleep patterns. causing added challenges to adolescents’ emotional and behavioral problems.
Objective To identify the association between sleep disorders with emotional and behavioral problems during the COVID-19 pandemic in urban and rural adolescents.
Methods We conducted a cross-sectional study among adolescents aged 12-18 years from November to December 2021 in two provinces, DKI Jakarta and Riau Islands. We recruited students consecutively from randomly selected junior and senior high schools. We used the Strengths and Difficulties Questionnaire (SDQ) and the Pittsburgh Sleep Quality Index (PSQI) to screen for emotional and behavioral problems and for sleep disorders, respectively. The questionnaires were sent electronically to each subject after obtaining parental consent.
Results There were 400 subjects included in our study, of which 64% were female. The prevalences of COVID-19 amongst subjects in urban and rural areas were COVID-19 12.5% and 5.5%, respectively. Emotional and behavioral disorders as well as sleep disorders were more common in rural than urban areas (13 vs. 11.5% and 50.5% vs. 38%; P=0.012, respectively). Sleep disorders were associated with the SDQ subscales of emotional symptoms [PR 4.88 (95%CI 2.97 to 8.03); P<0.01), conduct problems [PR 3.71 (95%CI 1.53 to 9.04); P=0.02), hyperactivity/inattention [PR 6.05 (95%CI 2.58 to 16.17); P<0.01], and peer relationship problems [PR 3.28 (95%CI 1.33 to 8.09); P<0.01).
Conclusion Sleep disorders among adolescents during COVID-19 pandemic were associated with emotional and behavioral problems. Adolescents who live in rural areas were more likely to have sleep disorders, emotional and behavioral problems.

Published: December 2023

Background Hypoalbuminemia and malnutrition are common factors that can adversely affect wound healing and increase the risk of postoperative infections. Improvements in albumin and preoperative nutritional status are expected to reduce the incidence of complications following postoperative abdominal surgery.
Objective To evaluate the roles of hypoalbuminemia and poor preoperative nutritional status as prognostic factors for postoperative complications in pediatric patients undergoing major abdominal surgery.
Methods This retrospective cohort study included pediatric patients aged 1 month to 18 years who underwent major abdominal surgery and were treated in the pediatric intensive care unit (PICU) of Dr. Sardjito Hospital between January 1, 2017 to December 31, 2021. The primary was the incidence of postoperative complications within 14 days after the surgical procedure.
Results Out of the 201 pediatric patients included in the study, 54.7% were male. We observed an overall complication rate of 21.3% following abdominal surgery, with sepsis as the most frequent, affecting 14.9% of the cases. On average, postoperative complications occurred approximately 10.9 days after surgery. Multivariate analysis identified severe acute malnutrition [hazard ratio (HR) 2.09 (95%CI 1.01 to 4.33); P=0.047], preoperative hypoalbuminemia of >2.5 to 3.0 g/dL [HR 3.64 (95%CI 1.57 to 8.41); P=0.003], preoperative hypoalbuminemia ?2.5 g/dL [HR 3.1 (95%CI 1.11 to 8.64); P=0.03], and age <1 year [HR 2.16 (95%CI 1.09 to 4.11); P=0.026] as significant prognostic factors for post-abdominal surgery complications in children.
Conclusion Preoperative severe acute malnutrition and preoperative hypoalbuminemia of ?3 g/dL are significant prognostic factors for the occurrence of postoperative complications in pediatric patients undergoing abdominal surgery. Infants less than one year of age are at increased risk of such complications.
Desyatov. Images of Epochs and Historical Periods in the Russian Culture of the 20th century. Basic Actions.
Authors: Десятов Вячеслав Владимирович 
Published: December 2023

In the history of Russia of the 20th century, there are nine periods, each of which is represented in artistic culture by one or another action, type of activity, which can be called the main characteristics for these periods. The images of historical periods and epochs are determined by such dominant themes that have become established in art and have become (in the semiotic aspect of research) symbols of a particular time. For example, dance remained a relevant symbol of cultural self-determination on the principle of affirmation/denial for three periods: dance proper, war, and labor. The chosen approach allows us to detect rather intense historical and cultural dynamics. The artistic culture of Russia of the 20th century was aimed at identifying new processes in the social and private life of a person. The activity of several periods is connected with the philosophy of F. Nietzsche, the period of labor — with the philosophy of K. Marx. Russian art of the 20th century reflected not only the human activity, but also the rapid change of its prevailing types.

Este artigo tem por finalidade apresentar um recorte da dissertação de Mestrado desenvolvida no Programa de Pós-Graduação em Educação Ambiental- PPGEA, da Universidade Federal do Rio Grande- FURG. Apresentamos a proposta investigativa com as crianças que vivem em uma ilha e estudam em uma escola do campo. Este estudo corresponde a necessidade de ampliar e qualificar o diálogo e reflexão sobre territórios invisibilizados pelas produções teóricas, tendo como foco a perspectiva das crianças no lugar. A pesquisa foi realizada em uma escola do campo na Ilha dos Marinheiros, no extremo sul do Rio Grande do Sul, e a permanência na escola teve embasamento teórico metodológico na Inserção Ecológica, com o registro em diário de Campo e gravação de áudio. Participaram da pesquisa quinze crianças da Educação Infantil e do Ensino Fundamental. Os resultados demonstram características singulares sobre as culturas infantis na ilha e que mobilizaram a visibilidade de infâncias em territórios litorâneos. Ao considerar o tempo-espaço na perspectiva das crianças, é possível identificar o lugar em que se situa a escola de ilha como um formador de subjetividades e experiências com a natureza na sua totalidade.
Numerical simulation of a novel small water turbine generator for installation in a deep-flow hydroponics system
Authors: Lahamornchaiyakul Werayoot 
Published: December 2023

Hydroponics systems are crucial for providing sustainable and cost-effective choices when soils are unavailable for conventional farming. The application of water flow rates within hydroponics systems to generate electricity is another idea that can be used in the field of power generation. This paper presents the determination of the mechanical power efficiency of a novel small water turbine generator for use in a deep-flow hydroponics system (DFT). The system was designed, analysed, and calculated for the most suitable geometries of the water pipeline inlet, DFT system, main structure of the PVC Tee Pipe Fitting, and a water turbine wheel using computational fluid dynamics software. The diameter of the water turbine wheel in this research was 48 mm. A DFT hydroponic system was modelled for the purposes of this research. We conducted a numerical simulation with water flow rates of 6, 8, and 10 l/min to evaluate the turbulent kinetic energy distribution in the DFT hydroponic system. The numerical simulation employed the control volume methodology, and the k-epsilon turbulence model was applied to obtain the computational conclusions. The highest torque and power that a novel small water turbine for installation in a DFT system could generate at a maximum flow rate of 0.000167 m3/s were 0.082 N.m. and 1.9568 watts, respectively. The forces generated by the fluid's speed and pressure can then be transferred to the building process of a novel small water turbine wheel. The FEA numerical result shows that the maximum value of the total deformation at a wheel speed of 228 rpm is 7.0 x 10-5 mm. The numerical simulations used in this study could potentially be used to further develop prototypes for innovative miniature water turbines that generate commercial electricity.
On Shifting Social and Urban Landscapes in Uruk under Nabû-kudurrī-uṣur II
Authors: Sandowicz Małgorzata , Wunsch Cornelia , Zawadzki Stefan 
Published: December 2023

AbstractThis paper discusses a small dossier of four documents concerning a house that stood in Neo-Babylonian Uruk. These documents, among which are two previously unpublished texts, offer a rare opportunity to follow the history of one property and one neighborhood over a period of more than half a century. Apart from supplying unique long-term data on property prices in Uruk, the dossier provides insight into various social and political changes that shaped Uruk’s urban landscape in the late seventh and early sixth centuries BC. In particular, it contributes to the evidence concerning a dramatic purge of Uruk elites that took place in the middle of Nabû-kudurrī-uṣur (Nebuchadnezzar) II’s reign.
BER performance analysis of MWIR and SWIR FSO links utilizing aperture averaging technique considering turbulence and various visibility situations with pointing errors
Authors: Mukherjee Shibabrata , Paul Sujoy , Mazumdar Saswati 
Published: December 2023

Abstract
The atmospheric turbulence and various weather situations deteriorate the system performance of free space optical (FSO) communication. In this article, the ‘bit error rate’ (BER) performance of the ‘mid wavelength infrared’ (MWIR) and ‘short wavelength infrared’ (SWIR) FSO link has been evaluated utilizing the aperture averaging approach with pointing errors in the presence of turbulence and different visibility scenario like fog, haze, clear weather, etc. The transmitter and receiver are 6 km apart, the modulation method is on off keying (OOK), and several aperture sizes at the receiver side have been taken into consideration for the aperture averaging approaches, such as 100 mm, 150 mm, and 200 mm. Additionally, for analysis of the pointing error of both the wavelengths of the FSO link, different beam divergence angle of the transmitter (laser) has been considered. The BER performance is improved with optimum beam divergence angles. The optimization of the divergence angle is independent of wavelengths and visibility conditions. However, the BER has increased more below the optimized divergence angle compared to a larger angle. The MWIR link performs well in poor visibility conditions like fog, whereas the SWIR link fails for the same link distance in both conditions with and without pointing errors.

Local languages and the linguistic landscape: the visibility and role of Sardinian in town entry and street name signs
Authors: Mura Piergiorgio 
Published: December 2023

Abstract
The present study deals with the presence and role of the Sardinian language in the linguistic landscape of sixteen villages in the province of Oristano, Sardinia. Specifically, their entry signs and street name signs were photographed and analysed using both quantitative and qualitative approaches. In the entry signs, Sardinian was found to have a very strong presence, generating a high degree of bilingualism with Italian, as recommended by national and regional language policies. Systematic bilingualism could not, however, be observed in the street name signs, where Italian clearly prevails. Notwithstanding, the local language is visible in around a quarter of all street name signs. Complying with the provisions of national and regional legislations, Sardinian is used in the majority of street signs to recall the historical memory of the communities. Nonetheless, signs could be found where Sardinian is used in parallel bilingual texts to express exactly the same content as Italian, fostering a modern vision of the minority language. The present work shows how top-down language policies can be locally implemented or re-interpreted in the linguistic landscape; moreover, the article sheds light on how street naming can be exploited to influence society’s perception of minority languages and convey messages of local or regional/national identity.
The sociolinguistics of Luxembourgish football language: A case study of contact-induced lexical variation in a complex multilingual society
Authors: Conrad François 
Published: December 2023

Abstract
Luxembourgish is a Germanic language in Western Europe situated on the Germanic-Romance language border. The centuries-long multilingualism, that has included German and French as main contact languages, has led to much variation on all linguistic levels, yielding lexical doublets – contact-induced synonym pairs. The study presents the results from the online Lëtzebuerger Futtballsprooch ‘Luxembourgish football language’ survey (n = 1189 participants), set up to analyze the distribution of the variants of lexical doublets in the special language of football in order to exemplify the mechanisms of contact-induced lexical variation in Luxembourgish as a whole. The variation is correlated with sociodemographic and language biographical factors (quantitative analysis, beta regression). The study also introduces linguistic orientation as an overarching factor for the individual language biography that is useful to model the positioning of individuals in relation to the contact languages involved in a complex multilingual society. The results reveal a societal trend towards Germanic variants linked to the linguistic orientation of the participants towards German, mirroring sociolinguistic dynamics and changes.
University autonomy and the increasing shift to English in academic programmes at European universities: In dialogue with Liviu Matei

Published: December 2023

Abstract
This paper centres on a dialogue with Liviu Matei, Professor of Higher Education and Public Policy at Kings College London, which aims to transcend sociolinguistic disciplinary boundaries by exploring the increasing use of English for higher education academic programmes at European universities within the context of university autonomy. Once Provost of the Central European University, forced to move from Hungary to Austria when its institutional autonomy was increasingly infringed by the state, Liviu Matei’s academic work combines intellectual acuteness with experience, further deepened in the practice of consultation and applied policy research for influential international bodies and organisations, including the Council of Europe and the European Commission. With him, we consider in novel ways the role that legal reform granting a regulated autonomy to universities accompanied by a more corporate style of higher education governance may have played in the rampant growth in recent decades of English language academic programmes in the now European Higher Education Area (EHEA). We reflect on the historical and public policy contexts out of which English as a medium of instruction (EMI) arose, the regulated autonomy of universities by ministerial practices of steering at a distance, and widely obtaining political epistemologies and policy narratives.

Для більшості з нас галузі науки, техніки та математики є або такими, що захоплюють і надихають, або надзвичайно складними концепціями. Вони часто отримують репутацію «жорстких» наук. Жорсткий, як у значенні для розуміння і вивчення, так і з репутацією жорсткого, тобто такого, який залишає дуже мало місця для творчості або уяви. На думку авторів статті, технології LEGO сприяють тому, щоб і діти, і дорослі були захоплені наукою, зокрема математикою.
У статті наголошується, що для закладів дошкільної освіти використання LEGO конструктора з метою формування математичної компетентності в дітей старшого дошкільного віку є ефективним освітнім рішенням, а особливо в умовах пандемії COVID-19, оскільки заняття з LEGO-конструктором можна з легкістю впроваджувати дистанційно. Автори доводіть, що такі заняття розпалюють природну цікавість дітей, допомагаючи їм розвинути необхідні навички спілкування, творчості, співпраці та критичного мислення у цікавій і захоплюючій формі. У викладеному дослідженні описано, що гнучкі рішення ростуть разом з дітьми, коли вони вирішують проблеми і виявляють, як наука, техніка, інженерія та математика впливають на їхнє повсякденне життя.

Published: December 2023

In this paper, an analysis of the results of the evaluation of Indonesian language proficiency for foreign speakers is presented. The development of a standardized Indonesian language for foreign speakers (Bahasa Indonesia bagi Penutur Asing - BIPA) evaluation tool is currently considered very important. Currently, the existing evaluation tools are still made partially depending on the needs of institutions that provide the Indonesian language program for foreign speakers (BIPA). In addition, this need is also driven by the need for foreign speakers to measure their proficiency in Indonesian. Although there is an Indonesian Language Proficiency Test (UKBI) as an evaluation tool in Indonesia, UKBI is considered not in accordance with the needs of measuring the Indonesian language proficiency of foreign speakers because UKBI is still used to measure the Indonesian language skills of native speakers. This has become one of the problems in the field of evaluation of the Indonesian language, especially BIPA. The language evaluation tool used to measure a person’s foreign language proficiency always begins with a listening proficiency test. Listening is considered the gateway to other language proficiency. The solution to this problem is to analyze listening evaluation tools in foreign languages that are used continuously and continuously, such as the Test of English for International Communication (TOIEC), the Japanese-Language Proficiency Test (JLPT), and Diplôme d'études en langue française (DELF), which represents three continents; American, Asian, and European spoken by Indonesian speakers. This study used a descriptive method to solve this research problem. The results of this study describe the profile of the listening proficiency evaluation tool in foreign and Indonesian languages in three ways: 1) speakers (speaker stimulus presenter), 2) content, and 3) audio. Furthermore, the results of this analysis can also be used as the basis for developing the BIPA listening competency evaluation model.

The distress and anxiety brought about by the academic demands negatively influences student performance during the abrupt shift to full-online classes. However, the literature indicates that self-efficacy significantly alleviates the negative effect of distress and anxiety.The current study aims to determine the relationship of COVID-19 related distress and academic self-efficacy as well as investigate if anxiety is a moderator that aggravates the distress of Angeles University Foundation college students. A total of 223 college students’ participants were acquired from a voluntary convenience sample and participants answered the questionnaires through Google Forms, namely: The Online Learning Self-Efficacy (OLSE), The Kessler Psychological Distress Scale (K6), and The Coronavirus Pandemic Anxiety Scale (CPAS-11). Additionally, all statistical analyses were conducted using SPSS 23. Moreover, the hierarchical regression was conducted to determine if COVID-19 distress predicted academic self-efficacy (ASE) with anxiety as the moderator. The findings indicate that COVID-19 distress and anxiety negatively affect the beliefs of the students in their capacity to perform academic tasks. However, evidence failed to support the moderating role of anxiety between Covid-19 distress and academic self-efficacy.

Authors: Shyelendra Madansing Pardeshi Et al. 
Published: December 2023

Due to the expansion of world of the internet and the quick acceptance of platforms for social media, information is now able to exchange in ways never previously imagined in history of mankind. A social networking site like Twitter offers a forum where people may interact, discuss, as well as respond to specific issues via short entries, like tweets of 140 characters and fewer. Users may engage by utilizing the comment, like and share tabs on texts, videos, images and other content. Although platforms for social media are now so extensively utilized, individuals are creating as well as sharing so much information than shared before, which can be incorrect or unconnected to reality. It is difficult to identify erroneous or inaccurate statements in textual content autonomously and find emotions of people. In this paper, we suggest an Ensemble method for sentiment and emotion analysis. Different textual features of actual and Emotion and sentiment have been utilized. We used a publicly accessible dataset of twitter sentiment analysis that included total 48,247 authenticated tweets out of 23,947 of which were authentic positive texts labeled as binary 0s and 24,300 of which were negative texts labeled as binary 1s. In order to assess our approach, we used well-known (ML) machine learning techniques, these are Logistic Regression (LR), AdaBoost, Decision Tree (DT), SGD, XG-Boost as well as Naive Bayes. In order to get more accurate findings, we created a multi-model sentiment and emotion analyzing system utilizing the ensemble approach and the classifiers stated above. Our recommended ensemble learner method outperforms individual learners, according to an experimental study.
