Authors: Machado Alba Jorge
Published: April 2023

Purpose: The aim was to analyze the characteristics, treatment patterns, persistence, and clinical outcomes of Colombian patients with Non-Valvular Atrial Fibrillation (NVAF) under treatment with oral anticoagulants (OAs). Patients and methods: Retrospective cohort in patients with NVAF, aged ≥18 years and of any sex, the first prescription of an OA (index) between January/2013 and June/2018, with a follow-up until June/2019. Data from the clinical history, patient characteristics, pharmacological variables, treatment switch, cerebrovascular events and safety were searched. Descriptive analyzes were carried out. Results: A total of 2076 patients with NVAF were included. The 57.0% of patients were women and the mean age was 73.3±10.4 years. Patients were followed for a mean of 2.3±1.6 years. 8.7% received warfarin before the index date. The most frequent OA was rivaroxaban (n=950; 45.8%), followed by warfarin (n=459; 22.1%) and apixaban (n=405; 19.5%). Hypertension was present in 87.5%, diabetes mellitus in 22.6% and severe renal failure in 5.2%. The mean CHA₂DS₂-VASc Score was 3.6±1.5. The main efficacy and safety outcomes were stroke (3.1%) and gastrointestinal bleeding (2.0%) respectively. From these, most events were in patients using warfarin at index (3.5% for stroke and 4.1% for gastrointestinal bleeding). The 18.0% of patients switched index OA during follow-up, while 11.7% discontinued the treatment. Conclusion: The patients with NVAF in this study were mainly older adults with multiple comorbidities and high CHA₂DS₂-VASc score. The frequency of clinical events was similar to other observational studies, with low percentage of discontinuation.

Authors: Podgurskaya M. G. , Kanshina D. S. , Dimertsev A. V. , Alexandrov M. V. , Nikitin S. S.
Published: April 2023

Background. After-discharge (AD) activity is a pattern that differs from background corticography, represented by rhythmic stereotypical slow waves and/or repetitive spike discharges with ≥1 Hz frequency, recorded after cessation of electrical stimulation and lasting for more than 2 seconds. Despite the accumulated experience in the field of intraoperative neuromonitoring, there is no unified protocol for high-frequency stimulation of cortical functional areas (FAs) upon the AD event.

Objective: to demonstrate a need to change the intraoperative FAs mapping protocol in patients with brain tumor on awakening in cases of AD recording.

Material and methods. Two clinical cases of awake surgical functional mapping followed by resection of the brain tumor are presented. Multimodal monitoring included high-frequency stimulation according to the approved intrahospital protocol with maximum stimulation force of auditory-speech zones of 2.5 mA, electrocorticography, and subcortical dynamic mapping.

Results. In the first case, AD was registered while FAs mapping in a patient with a history of one epileptic seizure, upon reaching the maximum stimulation force of 2.5 mA, that was replaced by recording focal epileptiform activity with the following evolution to ictal generalized event and development of intraoperative convulsive seizure. In the second patient with a history of recurrent epileptic seizures, AD with spatiotemporal evolution of the pattern development of clinical ictal event was registered with stimulation at 2.5 mA. In both cases, the appearance of AD required to change mapping protocol with a stepwise decrease in stimulus strength to obtain cortical FAs data.

Conclusion. Registration of AD is the basis for changing the protocol of high-frequency cortical stimulation in surgical treatment of brain tumor FAs.

Published: April 2023

Background: Breast cancer is responsible for 13% of deaths among women globally. The present study aimed to assess adverse drug reactions (ADRs) in breast cancer patients receiving treatment in a tertiary care teaching hospital.
Methods: This retrospective and descriptive study was conducted in the oncology department at sree mookambika institute of medical sciences, Kulasekharam, covering six months from May 2022 to November 2022. The study includes patients of any age diagnosed with breast cancer, treated with chemotherapy, and who developed at least one ADR during or after treatment. Patients who developed ADRs due to fresh blood or blood product infusion and had a history of drug abuse or accidental poisoning were excluded from the study.
Results: Three hundred fifty-eight breast cancer patients were evaluated, of which 142 developed ADRs. The study revealed that breast cancer was most prevalent among women aged 41-50. Seven (4.92%) had a history of tobacco smoking, 129 (90.85%) patients were married, and only 13 (9.15%) were unmarried. The most commonly prescribed chemotherapeutic drug for breast cancer patients was docetaxel (19.01%), Cyclophosphamide (15.49%) and nab. paclitaxel (12.67%). The study found that the most frequent ADR observed among the patients was febrile neutropenia (18.30%), followed by nausea and vomiting 14.79%). Causality assessment reported that 61.27% (87) of the ADRs were probable, and 29.58% (42) were possible.
Conclusions:  Spontaneous adverse drug reporting and structured management are essential for monitoring the safe use of drugs. The findings suggest the need for effective pharmacovigilance programs and improved patient care in administering chemotherapeutic agents.

Published: April 2023

Background: After decades of debate and controversy, the short-term benefits and at least equivalent long-term outcomes of laparoscopic colon surgery compared to open surgery has now been well established.
Methods: In this article, short- and medium -term outcomes of patients undergoing laparoscopic colorectal surgery for cancer in a tertiary care hospital is analysed. A retrospective analysis of prospectively collected data of all patients who had laparoscopic management of colorectal cancer (CRC) for 3 years was done. Patients were followed up for 2 years after treatment. The prospectively collected data was analysed to find out the incidence of complications, local or distant metastases and the survival rates.
Results: There were 65 patients who underwent laparoscopic surgery among 120 patients who had treatment for colorectal carcinoma in the study period. The 26 patients underwent low anterior resection followed by 14 patients   and 13 patients undergoing left colonic and right colonic resections respectively. While abdominoperineal resection was carried out in 6 patients, 3 each patients were treated by ultra-low anterior resection and subtotal colectomy. Morbidities of varying grade according to Clavien Dindo classification was less for laparoscopic surgery. Recurrence occurred in 14.8% at 2 years follow up. The 2-year survival rate was noted to be 87.7%   among the study group who underwent laparoscopic surgery.
Conclusions: Judicious selection of patients and the appropriate selection of technique help to achieve good short-and long-term results without compromising on oncological outcome in laparoscopic surgeries for colorectal malignancies.

Published: April 2023

Tumours of the small intestine are among the rarer conditions as compared to other tumours of the gastrointestinal tract. Among these, sarcomas hold a much lesser number in proportion to adenocarcinomas. Leiomyosarcomas occurring in the small intestine constitute an even smaller number, accounting for about 1% of malignant mesenchymal lesions in the gastrointestinal tract. Within the spectrum of LMS of the small intestine, the more common location encountered is the ileum, followed by the duodenum. The second part of the duodenum is usually implicated in most studied and reported cases of duodenal LMS. These tumours are known for their aggressive nature and their often-delayed presentation due to ill- defined symptomatology and diagnostic challenges. As a result of the above, even a century after the first reported case, their prognosis is poor. Here we report a case of a 64-year-old female who presented with vague complaints of abdominal discomfort and dyspepsia for a month and was diagnosed to have a mass lesion in the 2nd and 3rd part of the duodenum. Intraoperatively, she was found to have two separate mass lesions in D1 and D3 and was subjected to a pancreaticoduodenectomy. The mass lesions were pathologically categorized as leiomyosarcomas of the first and third part of the duodenum.

Published: April 2023

Bezoars are retained concretions of undigested foreign material that accumulate and coalesce within the gastrointestinal tract, most commonly in the stomach. A 12 years old male child presented to us with complaints of pain upper abdomen on and off for 2 months. He had a habit of biting and chewing doormat at home for several months. Physical examination revealed mild epigastric tenderness. Upper GI endoscopy revealed a mass of fibres in the stomach which was tightly organised and too large to safely remove endoscopically in toto. Hence patient was taken up for surgery and a mass of around 9×6 cm in size and oval in shape was removed from stomach. Postoperative recovery was uneventful. Doormatobezoars are rare cause of pain abdomen which can be treated safely and effectively surgically.

Published: April 2023

Adrenal myelolipoma is a benign neoplasm of the adrenal gland that is the second most common primary adrenal incidentaloma, following adrenocortical adenomas. It is composed of elements of adipose tissue and with varying amounts of hematopoietic components. In the past, these tumors were discovered at autopsy, with an incidence ranging from 0.08% to 0.4%. Today, with the widespread use of radiological studies such as ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI), the incidental detection of myelolipoma has become more common, constituting up to 10-15% of incidental adrenal masses. The patient was hospitalized for a 3-month history of discomfort in the right flank, swelling over the right hypochondriac area, constipation, retrosternal burning sensation, and early satiety. His vitals were stable but per abdominal examination revealed a mass in the right hypochondrium. B-mode ultrasound screening revealed an adrenal tumor. A hematological examination revealed thrombocytopenia. The presence of unilateral adrenal mass with the absence of new-onset hypertension with CECT suggestive of mixed tissue density mass with multiple ill-defined heterogeneously hypodense fat attenuation led to the primary diagnosis of an adrenal mass After correction of thrombocytopenia, the mass was excised and subjected to histological evaluation. The histological study results corroborated with the original diagnosis of unilateral adrenal myelolipomas. The patient was followed up for 2 months postoperatively and was found to be relieved from the presenting symptoms with no postoperative complications. Adrenal myelolipoma is an uncommon, benign, and hormonally inactive adrenal gland tumor. It may present with symptoms due to compression of adjacent structures which warrants a surgical excision.

Published: April 2023

Gastric neuroendocrine tumour (GNET), also known as carcinoids, are a very rare cause of gastric outlet obstruction and arise from entero-chromaffin like cells of the mucosa. They account for 0.2/1000001 population and 8.7% of all Gastrointestinal carcinoids. They are four types based on the degree of differentiation, cell of origin and other pathologic features. Type 4 GNET are referred to as neuroendocrine carcinoma accounting for <1% of GNET. They are aggressive, poorly differentiated, locally invasive tumours with metastatic potential. Hence, they require an aggressive approach in terms of surgery and multimodality adjuvant treatment. Our patient is an elderly hypertensive who had complaints of projectile vomiting over ten days associated with weight loss over the last two years. A diagnosis of gastric outlet obstruction was made, and she underwent a contrast CT scan and endoscopy twice, both being suggestive of malignancy involving the antrum region however, the endoscopic biopsy showed unremarkable histology. Subsequently, she underwent emergency laparotomy in which there was a hard growth palpable in the antrum for which distal gastrectomy, D1 lymphadenectomy and gastrojejunostomy were done. Post-op HPE was suggestive of neuroendocrine carcinoma, thus, depicting our difficulty with diagnosis based on pre-op biopsy report given its rarity.

Penetrating injuries are more typical overall, and traumatic damage to the duodenum only happens in 3 to 5% of individuals with abdominal injury. The majority of blunt injuries in the US are brought on by auto accidents. Lesions are evenly dispersed across the other sections of the duodenum, with the second segment being more frequently afflicted. Duodenal damage symptoms are non-specific and could be less noticeable after retroperitoneal surgery. Computed tomography (CT) is used to evaluate the duodenum in the diagnosis of duodenal injury in hemodynamically stable patients. CT findings related to this evaluation include duodenal thickening, periduodenal fluid, extraluminal air, and accumulation of heterogeneous fluid (clot) close to the site of injury. According to the mechanism and severity of the damage, the care of duodenal lesions should be cautious in patients with grade I or grade II closed duodenal hematoma who are hemodynamically stable. When duodenal lesions need to be repaired, surgery is necessary. With death rates of about 15%, duodenal injury complications include intra-abdominal abscess, duodenal fistula, and post-traumatic pancreatitis.

Compost is an inexpensive agricultural waste which improves soil health and quality. The experiment was carried out to assess the influence of compost and mycorrhizal inoculation (Glomus mosseae) on soil properties and growth of yellow bell pepper in pots under screen house conditions, in a completely randomized design with three replicates. The treatments included mycorrhizal inoculation only (C0M1), compost at 20 t ha-1 only (C1M0), compost at 30 t ha-1 only (C2M0), compost and mycorrhizal inoculation at 20 t ha-1 (C1M1), compost and mycorrhizal inoculation at 30 t ha-1 (C2M1) and control (no amendment / uninoculated). Compost and mycorrhizal inoculation (C1M1 and C2M1) significantly improved soil N, P and K compared to control. Inoculation with mycorrhizal only (C0M1) increased uptake of N, P, K, Ca and Mg compared to uninoculated. Co-utilization of compost and mycorrhizal inoculation significantly increased root and shoot dry biomass compared to uninoculated. The highest fruit yield was obtained at C2M1 followed by C1M1 in comparison to compost application only. Treatment C2M1 recorded the highest prevalence of percent root colonization. This suggests that compost and Glomus mossea could be considered to have a sustainable potential for better growth and yield performance in the production of yellow bell pepper in an Alfisol.

Published: April 2023

The development of Western Siberia is one of the most large-scale scientific, industrial and socio-economic projects of the country in the 20th century. The state approach, scientific substantiation, production of the necessary equipment, organization of transport and exploration work were linked into a single integrated state project. As part of the USSR Ministry of Geology, the Main Directorate for Oil and Gas Exploration was created, and on January 15, 1948, an order was signed to organize the first oil exploration expedition in Tyumen. In January 1950, the Scientific and Technical Council of the USSR Ministry of Geology adopted a master plan for the study and development of the West Siberian Plate, including the placement of 26 reference wells, regional seismic profiles and prospecting in the area of ​​reference wells on its territory. As a result, the gas fields of the Berezovskiy region and the Shaimskoe, Megionskoe and Ust’-Balykskoe oil fields were discovered. Efficient organization of work and the state approach made it possible to discover large oil reserves in the Shirotny Ob region and unique natural gas reserves in the north of Western Siberia in a short time. In December 1963, a special resolution of the Council of Ministers of the USSR on preparation for the trial operation of deposits, on the creation of infrastructure for the development of geology and oil production, research and industrial institutes was adopted. Achievements of geologists have provided the necessary basis for the creation of the largest fuel and energy complex. It was associated with the social and economic development of the region and the country
Justification of the optimal type of well completion profile based on a retrospective assessment of the technical and economic performance indicators
Authors: Zaitsev Roman A. , Martyushev Dmitriy A.
Published: April 2023

To date, significant foreign and domestic experience has been accumulated in the construction and operation of horizontal, multilateral and multilateral wells, as well as the restoration of an idle well stock by drilling sidetracks and sidetracks into various productive formations: low-permeability and highly dissected, with low values of effective oil-saturated thicknesses, degraded hydrodynamic connection with the contour area, etc. In this regard, it becomes extremely important to make a decision on choosing the optimal well profile in specific geological and physical conditions. The relevance of the work is also confirmed by the fact that at some development sites there is a decrease in the oil production rate of horizontal wells to the level of directional wells in the initial period of operation. Based on a significant difference in the reservoir properties of oil fields in the Perm Territory, all the analyzed objects operated by horizontal wells are combined into several groups: “northern” (N) and two “southern” (S1 and S2). The main parameter in the selection of groups was the coefficient of mobility of oil. The well-by-well technical and economic assessment performed in the article, based on the actual values of production over a long period, made it possible to identify the optimal well profile depending on the geological and physical characteristics of the reservoir. Combining the main geological characteristics that affect the technological parameters of well operation, with an economic assessment, the dependences of the net present value on the formation hydraulic conductivity were built. Dependences built for the first time make it possible to reasonably select the well profile in specific geological and physical conditions. Also in the work for a variety of geological and physical conditions, the value of the minimum profitable oil production for various well profiles is determined. Thus, the basis has been created, which is necessary for determining the profile of wells when planning production drilling.

Authors: ÜNAL ENGİNAR Ayşe
Published: April 2023

Objectives: To compare patients with symptomatic nodal hand osteoarthritis (OA) with a control group in respect of inflammation parameters, uric acid, and hematological parameters.
Methods: The study included 50 post-menopausal female patients, aged 40-80 years, diagnosed with symptomatic nodal hand OA, and a control group of 50 post-menopausal females in the same age range with no hand OA. Patient data including age, monocyte, neutrophil, lymphocyte, and thrombocyte counts, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, uric acid level, and the Kellgren-Lawrence (KL) score obtained from evaluations of hand radiographs, were recorded retrospectively from the hospital information system. The neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and monocyte-lymphocyte ratio (MLR) were calculated. The data were compared between the two groups.
Results: The data of 100 females were compared, comprising a patient group of 50 patients with symptomatic nodal OA, and a control group of 50 females. Age, monocyte, neutrophil, lymphocyte, and thrombocyte counts, NLR, PLR, MLR, ESR, CRP, and uric acid level were compared. With the exception of MLR and ESR, no statistically significant difference was determined between the two groups. The MLR was determined to be statistically significantly higher in the control group than in the patient group (p = 0.024). The ESR was determined to be statistically significantly higher in the patient group than in the control group p < 0.001). When patients with a KL score of 2 and 3 were compared, with the exception of age, no other difference was determined. Patients with a KL score of 3 were seen to be significantly older (p = 0.032).
Conclusions: ESR was determined to be significantly higher in patients with symptomatic nodal OA. Clarification of the relationship between inflammation, uric acid, and hand OA, which is a heterogeneous disease, will be useful in the follow-up and treatment of patients.

Desde el enfoque biográfico narrativo, el presente artículo pretende dar cuenta de la importancia de la custodia de semillas, a partir de las casas comunitarias pertenecientes a la Red de Mercados Agroecológicos Campesinos del Valle del Cauca, en 2021, en relación con –por un lado– la autonomía, soberanía y seguridad alimentaria, y –por otro– unos problemas socioambientales en particular, tales como el ingreso de los transgénicos y ciertas disposiciones normativas que han afectado y afectan algunas prácticas alimentarias. En virtud de lo anterior, se tomaron como unidades de estudio once casas comunitarias de Semillas Libres del Valle del Cauca, durante 2021. Con campesinos y pequeños productores, se llevaron a cabo entrevistas semiestructuradas, a través de las cuales se narraron experiencias de vida en correspondencia con la autonomía, seguridad y soberanía alimentaria; esta información fue sistematizada y analizada mediante matrices, con las que se hizo una triangulación de los datos en su contexto determinado, junto a los postulados teóricos. Dentro de los principales hallazgos se encontró que para los custodios de semillas es primordial manejar sus semillas de una manera autónoma tanto para su producción natural como en su forma tradicional y ancestral de sembrar y comercializar sus cosechas; estos individuos son quienes posibilitan un desarrollo sostenible por medio de las buenas prácticas de la custodia de semillas autóctonas.
Water distribution network expansion: an evaluation from the perspective of complex networks and hydraulic criteria
Authors: Anchieta Thomaz , Meirelles Gustavo , Carpitella Silvia , Brentan Bruno , Izquierdo Joaquin
Published: April 2023

The expansion of water distribution networks is nowadays essential to meet the pressing population growth in many cities worldwide. With the subsequent increase in water demand, the hydraulic behaviour of a water supply system can change dramatically due to the significant head losses in the pipes caused by the larger flows released by pumping systems and reservoirs to supply the higher water consumption of the network. Strategical studies are necessary to delimit risk regions where a demand increase may affect the system too negatively. To analyse expansion scenarios with the lowest risk of failure and damage for the supply network operations, this research studies hydraulic performance and connectivity under various demand increase scenarios using calculations of complex network metrics together with relevant hydraulic criteria. For these calculations, this research, developed in Python, uses, respectively, the NetworkX 2.5 and WNTR 0.3.0 packages. The C-Town network is employed as a case study, and demand increasing scenarios are implemented on 30 nodes along the peripheral regions of the network to simulate the growth of the cities. Then, these scenarios are evaluated using the TOPSIS methodology, thus determining the best and worst sectors to expand the capacity of the network.

Up to 30% of all drinking water is wasted due to leaks in water distribution networks (WDNs). In times of drought and water shortage, wasting so much drinking water has a considerable environmental and financial cost. In this paper, we present a microservice architecture for leak localization in WDNs, where heterogeneous sources of data consisting of sensor measurements, Geographic Information System (GIS), and Customer Relationship Management (CRM) data are used to feed a leak monitoring solution which combines hybrid data-driven and model-based leak detection and localization methodologies. The solution is validated using in-field leak experiments in an operational WDN. The final leak probabilities are presented in a visualization dashboard. The search zone for most leaks is reduced to a few kilometers or less. For other leaks, the solution is able to indicate a larger search zone to reflect its higher leak prediction uncertainty.

The original meaning of many modern Kazakh words of Arabic-Iranian origin is associated with ethical categories, spiritual and moral values. In this study aimed at identifying a layer of words borrowed by the Kazakh language from the Arabic and Iranian languages, and investigating their semantic development a descriptive method and methods of lexicographic and lexico-semantic analyses of words were applied. The study results demonstrated that the semantic development of Muslim terms in the Kazakh language included reinterpretation, and their acquisition of new meanings in the Kazakh literary language. Desacralization of religious concepts signified by these words occurred in the languages from which these words were later borrowed by the Kazakh language.
Ethno-cultural Aura of Language Images in the Light of Cognitive Linguopoetics

Published: April 2023

The nature and essence of the language image are considered from the standpoint of modern cognitive linguopoetics, its differences from the general philological concepts of “image” and “imagery” are shown. According to the authors’ idea, the language image is considered in line with creative discursive activity. It is proved that language images integrating real ideas about the world picture and the author’s emotional attitude to them synergetically create an ethno-cultural aura of a literary text. Discourse, due to the multiplicity of its components, is a speech-thinking platform for forming a language image. The latter is considered by us as a synergetic phenomenon in the aspect of a multichannel derivative stimulus and a self-organizing phenomenon in open systems of linguocreative thinking. The article substantiates that in a literary text a language image is generated not by a real, but by a so-called communicative and aesthetically significant event, i.e. a literary discourse - the denotative aura of language images. The analysis shows that the language image is formed not only by the text itself, but also by various extralinguistic factors (knowledge of the world, opinions, values) that play an important role in understanding, interpreting and perceiving verbal images of a communicative event. Therefore, the work interprets all the main (event and non-event) elements of the text’s discursive situation, forming a complex language image. The extralinguistic factors determining the semantic architectonics of the internal context and actively participating in the formation of the ethno-cultural shell of language images are revealed. Each of these images serves as a shadow cloud of the internal context, an element of the ethno-cultural aura of the speech activity. In contrast to the existing stereotypes, according to which the concept and image are considered products of different mental operations: the first is analytical, and the second is synthetic, the article proves that the genesis of language image is characterized by their fusion. At the initial stage, there is an analytical perception of the signs of a denotative situation, and at the final stage, their synthesis. Ultimately, the genetic connection of such phenomena as literary text, discourse and concept generates the ethno-cultural aura of a pictorial-speech work.

Developping a multilingual corpus of terminology in linguistics can contribute to better organization and standardization of Russian and Chinese terms in the chosen field on the base of the existing works on the material of the English language. The scope of the project is to fill the lacunae, to disambiguate homonymy, to facilitate the choice of appropriate translation of a linguistic term and understanding of its context. The issue of the absence of Russian-Chinese-English and Chinese-Russian-English terminological dictionaries and the general desynchronization of terminological systems have been repeatedly mentioned in scientific works focused on the description of the language for special purposes. The search for a solution to these theoretical issues will help to find an algorithm for organizing the corpus of terms both within individual scientific disciplines and in interdisciplinary areas of arts and humanities. Multilingual corpus of terminology in linguistics implies the development of methodological recommendations and a complex of teaching materials including the digital ones, which will help foreign students to use the terms according to their level of language proficiency. The project is a continuation of a collective work oriented to the research of a language for professional communication. Language for professional communication is a functional type of a natural language the units of which transfer special knowledge. The absence of this knowledge makes professional communication impossible in the ways of perception, interpretation, translation and, creation of scientific texts in writing.

Introducción: Los humedales cumplen una importante función ecológica como hábitats para diversos grupos de aves, en específico las de hábitos acuáticos. A pesar de su alta diversidad, en México existen escasos estudios sobre la composición y dinámica de la comunidad de aves en humedales. Objetivo: evaluar la dinámica espacial y temporal de la comunidad de aves acuáticas y rapaces en humedales. Métodos: para caracterizar las aves acuáticas y rapaces se realizaron transectos de distancia variable mensualmente durante noviembre de 2019 a febrero de 2022 humedales ubicados en la Zona Metropolitana de la Ciudad de México. Resultados: se registraron un total de 105 especies de aves. Los valores más altos de diversidad se encontraron en la Laguna de Zumpango (91 especies) y en el Lago Nabor Carrillo (91). La mayoría de estas especies son migratorias (63%), mientras que 30% son residentes, y 7% son introducidas. Se encontraron diferencias espaciales y temporales significativas (p<0,05) en la composición de la comunidad de aves. Conclusión: La mayor diversidad fue en Zumpango y Nabor Carrillo, y la mayoría fueron especies migratorias.
Problem and Project-based Learning as an Effective Environmental Education (EE) Methods: A Case of Textbook Development in Medan City Schools
Authors: Rachman Indriyani , Matsumoto Toru
Published: April 2023

Environmental education (EE) is a tool for educating people about the environment, and EE textbooks are an essential resource for this purpose. This book was created by a group of elementary, middle, and high school teachers in the Medan City area who had yet to gain experience in textbook writing. A combination of problem and project-based learning (PBL and PjBL) by triggering teachers to develop a textbook for EE was carefully conducted. The project took three years, during which the teachers worked on conceptualizing and setting goals, selecting themes, creating the content, and designing teaching materials. Initially, the teachers conducted a poll which acted as a PBL approach to identify the most pressing environmental issues faced by the people of Medan City. This poll showed that waste management was the most crucial issue, followed by problems related to rivers, wastewater, waste disposal, and floods. The teachers then wrote chapters as a part of the PjBL approach for the EE book based on the identified issues and aligned with the EE curriculum. Over three years, the teachers tested the book with their students, evaluated the results, and revised it accordingly. The final questionnaire results showed that the experience of creating an EE book was valuable to the teachers and inspired them to consider making more EE resources in the future.
Online but Disconnected: Student Connectedness in Online Remote Learning i n Higher Education in New Zealand
Authors: Brown Stephen J.
Published: April 2023

New Zealand university students in the online learning environment may have feelings of disconnectedness, isolation, and suffer a lack of personal attention. Perhaps these universities are at a junction, where they can choose to offer students immersion into a virtual learning environment devoid of a physical presence, or a pathway which nurtures students’ learning in a hands-on, face-to-face, physical space.  Understanding student online connectedness, or their sense of belonging with the online virtual learning environment, may help navigate a path through this junction as the emergence of online remote learning becomes commonplace in New Zealand. This article suggests that universities should foster a virtual place of learning by developing an online social presence and promote open communication between faculty and students, and between students and their peers. Students are more likely to value online courses that foster a high degree of connectedness, and they are more likely to complete these courses. In this article, online student connectedness is defined and tools to measure it are described. Strategies to promote student connectedness in the online learning environment are suggested, for example, comprising social media and social networking sites which facilitate communication and increase social presence.
An Essay about Intercultural Sensitivity and Competence in Higher Education
Authors: Van Melle Jonathan , Ferreira Marco Maia
Published: April 2023

Intercultural sensitivity is one of the more influential fields of intercultural communication, engagement, equity, and inclusion. It describes the standard ways in which people experience, interpret, and interact across cultural differences. Intercultural sensitivity starts with the awareness that there are genuine differences between cultures and that these variations are commonly mirrored in the approaches by which people communicate and relate to one another. By recognizing how one experiences cultural predictions about one’s effectiveness of intercultural communication can be made. Educational interventions can be tailored to facilitate intercultural sensitivity development. Generally, this development signifies a move from an ethnocentric view to an ethnorelative view. Researchers have undertaken several approaches, not only to understand ethnocentrism but also to attempt to reduce it in Higher Education Institutions. In this essay, we first discuss the concepts of intercultural sensitivity and intercultural competence and how these are connected. Then, we present several studies focused on internationalisation practices to develop students’ intercultural sensitivity and/or competence, finalising with an alternative pedagogical approach to intercultural sensitivity development -The Creative Action Methodology (CAM).
