Published: September 2021

Many adaptations had to be made to classes worldwide amid the COVID-19 pandemic and keeping students engaged and interested in class became a priority for educators. This pandemic has posed a challenge since it forced schools to rapidly migrate the teaching-learning process to an online platform. Particularly, Gen-Z class engagement has been an issue for most teachers, because students tend to rapidly drift away from class; this, alongside the anxiety and stress over the future and the health of their loved ones, has made class engagement an even greater challenge. Using social media as a tool in class may seem unorthodox but given the main features that distinguish Gen-Z, it can be a useful tool to approach and engage them. In order to do so, three different phases of educational innovations were implemented, coronabunker, teaching with memes, and open thread. Each implementation built on the learnings from the previous one, to develop strategies targeted for the participants. The results indicated that students perceive these implementations as fun, when developing the posts from the thread activity, students stated that it also allowed them to integrate curricular content. This generation shares unique language and cultural references that may provide educators a rare glimpse to approach and start to build a bridge that would eventually diminish the gap between generations.

This paper analyses faculty’s emotions during the Covid-19 pandemic and identifies their characteristics and possible emotional vulnerability in order to provide decision makers with the information necessary to better serve this community. This action is important since teaching is catalogued as the fourth most stressful profession in the world, and due to adverse conditions, this could increase, as reported by the literature. This research, carried out in Mexico during April 2020, answers the questions: What are the main concerns of instructors at the beginning of the COVID-19 lockdown in a private Mexican university? What are their perceptions about their health and the demographic characteristics of these instructors during the COVID-19 lockdown? We conducted a survey for 104 professors of the South-Centre Region of the Tecnologico de Monterrey and the results were analysed using a mixed methodology which included text analysis and descriptive and inference statistics. Results indicated that the mayor concerns were health, getting sick, contagion and uncertainty. Other concerns included socio-economic consequences of lockdown and their teaching performance under the online modality. Regarding health, the faculty reported feeling more frequently concerned, followed by feeling calm, excellent, at risk and vulnerable and 36% revealed having negative feelings regarding their health. Based on their generation, negative feelings increased the older the faculty member was, from 28% of Millennials to 55% of Boomers. Main concerns of professoriate are dependent of gender and generation; however, these are independent of the academic degree, the professional experience and the relationship status. Furthermore, we mention the strategies implemented by the Tecnologico de Monterrey to assure the emotional wellbeing of its faculty.

ONLINE CRIMINAL CLINIC
Authors:   Tecnologico de Monterrey, México, Vera JV
Published: September 2021

Confinement brought with it virtual classes, and that teaching channel that was once the exception, became the rule, but, what are the implications that this change produced for crime victims who seek access to justice? The main objective of this contribution is to exemplify, by sharing the results and experiences produced by the criminal clinic taught in virtual format of the Campus Puebla, how online clinical teaching, as well as a face-to-face legal clinic execution, achieves a differentiated learning in relation to the traditional methodology of teaching, that is, the development of disciplinary and transversal educational competences for criminal litigation through experiential learning. The penal clinic at the Tecnológico de Monterrey in Puebla City, Mexico, was established four years ago from the project "Voice of the Victims" in conjunction with the Arizona State University and sponsored by the Merida Initiative. The criminal clinic works with an external institution called "socio-trainer". By acquiring knowledge about the role of legal advisors to victims, and by taking an active part in the entire criminal process, students develop diverse transversal competences like professional responsibility, human sense, and professional ethics; In addition to that, this contribution aims to also showcase the online criminal clinic execution limitations and opportunities of development when compared to the face-to-face or in person clinic development. The methodology follows a format of assigning real criminal cases to students who assume the role of victim lawyers; They are guided by professors from the University and a lawyer from the Socio-trainer Institution. They are evaluated according to the procedural progress of the assigned cases, as well as activities and alternatives for access to justice such as: counseling for crime victims, preparation of briefs and guidelines for hearings. In the August-December 2020 semester, the clinic was executed online, and the methodology underwent an important transformation in its academic and practical aspects, as well as in the care and follow-up of assigned criminal cases. The process had negative implications due to the lack of constant interaction with the victims and the authorities, but this did not substantially affect the student's learning.

Published: September 2021

The objective of the article was to determine the effect of developer didactics in university education, related to teaching, learning and training of graduate professionals, strengthening their identity and empathy with social reality. University education must prepare citizens, its objective is to prepare, train and educate. In this process, skills, abilities, capacities and competencies are acquired to solve society's problems through research, scientific knowledge, which is used to solve them. The developer didactics allowed to overcome the difficulties of the educational teaching process, which was based on constructivism that allowed affirming learning. The methods of learning based on problems and cooperative were applied. The sample consisted of 121 undergraduate students, distributed in 3 time groups. The quality of the model for the proposed learningteaching process allowed the achievement of significant knowledge. The evaluation was participatory and innovative in nature, not directive; the contents were evaluated at the level of knowledge, procedures and attitudes, within the framework of the professional profile and the exercise of their professional career. The research showed that through the application of developer didactics, general, professional and specialized competences were significantly promoted in students. This process was materialized in an evaluation of a participatory nature, of a continuous nature in the subject, being a significant achievement, with an average of more than 17. Therefore, the approach based on the development didactics in a curriculum by competencies, is highly significant and representative in the three investigated samples.

IMPLEMENTATION OF NEW TECHNOLOGIES IN TRADITIONAL HANDCRAFTS: EXAMPLES FROM THE HIGHER EDUCATION
Authors:   International Hellenic University, Greece, Souliotou AZ ,   University of Western Macedonia, Greece
Published: September 2021

The implementation of new technologies in traditional handcrafts is being an increasingly popular interdisciplinary practice in arts, education and other aspects of life including entertainment, interior and public design. The present research explores the possibilities of the implementation of electrical and light technologies in traditional handcrafts with the purpose of providing a rich multisensory experience. The implied methodology involves practice-based research through creation of handcrafts with implementation of new technologies by the author-instructor and students in the Higher Education. Students’ handmade creations involve a wide range of media: paintings, sculptures, collage, puppets and other constructions with implemented new technologies including light effects, coding, movement sensors and renewable energy in contexts of art, education, interior and public space. The implementation of new technologies turned out to be a hands-on art-and-technology practice with multiple benefits in education. Students realised that many different aspects of the traditional handcrafts were revealed with the use of new technologies and that their implementation brings traditional handcrafts to (another) life. Furthermore, it became clear that students’ practice through the implementation of new technologies in traditional handcrafts constitutes their own preparation for applying these technologies to children’s handmade constructions and, thus, it is possible to enhance and enrich children’s creative experience. The stimulation of many senses thanks to the implementation of new technologies can also improve visual and multisensory culture, foster creativity and contribute to cultural and technological literacy. The tension between the traditional and the contemporary through the coexistence of different media proved to be a fruitful synergy making the final whole more interesting than the sum of its parts.

THE ROAD TO LEARNING: USING GAMIFICATION AS AN EDUCATIONAL INNOVATION IN THE ERA OF DIGITAL EDUCATION
Authors:   Tecnológico de Monterrey,Mexico, Oropeza I , Muñoz R ,   Tecnológico de Monterrey,Mexico, Madero S ,   Tecnológico de Monterrey,Mexico
Published: September 2021

As an educational innovation, Gamification is a process where the teachinglearning process integrates the principles of playfulness and games, motivating participation in a safe environment that permits mistakes without consequences. As a professional professors it was detected that the students assume, under the managerial concept, that as leaders, they are the ones who should give the orders, are responsible for the project, and in charge of others. With gamification, it is intended that they understand that as leaders, they form networks of teams with mutual interests (Draft and Lane, 2018). This raises the following question: Could gamification be the innovation that ensures students develop leadership skills and collaborative work? During the August-December semester of 2020, the game named ´Ñu da meya was designed and implemented where students taking two courses with little similarity helped each other in a fictitious customer-supplier working relationship where each student played a role to reach a common goal. The role play consists of one Fun Quest and five stages: Preparation, Brief, Script, Negotiation and the Master stage. Through the game 'Ñu da meya, the students acquired knowledge through active learning. They developed the necessary leadership that allowed them to take the initiative in any field, challenge paradigms, and make things happen, ethically. This document shows how through gamification the students develop some competences and discover the value of leadership and collaborative work in realistic scenarios, where each of the participants played a role contributing to collaborative work, problem-solving, leadership, communication and decisionmaking in a shared environment of commitment. The importance of this project is understanding what makes teamwork efficient at the university level and for students’ discovering the value of leadership and collaborative work and how to exercise them. This project demonstrates the tangible benefits of collaboration between different schools to perform multidisciplinary work.

When students enter the university, they undertake a series of activities that can potentially stress them and cause their training experience to be not ideal for their learning. It is the responsibility of higher education institutions to provide an optimal environment to acquire knowledge and skills; therefore, they must have instruments that measure the degrees of stress generated. This study's objective was to determine a scale's psychometric properties that measure stressful characteristics in educational environments, namely Semestre i. A cross-sectional study with a survey design was carried out. Two hundred sixty-two university students participated, 122 of whom were men with a mean age of 22.6 (SD = 1.4), and 140 were women with a mean age of 22.1 (SD = 1.2). A scale comprised of saturation dimensions (11 items) and unpredictability dimensions (7 items) was obtained. An Exploratory Factor Analysis was performed with the Maximum Likelihood extraction method and oblimin rotation to determine the construct validity. It was possible to explain 52.3% of the variance (X 2 = 2566.64, df = 153, p = .001; KMO = .92) in two dimensions, namely, high demand environment and unpredictable environment. Reliability was calculated through internal consistency using the Cronbach coefficient, obtaining an alpha value of .92. A parsimonious scale was obtained with the necessary evidence to conclude that valid and reliable data can be obtained, allowing the students' stressful educational contexts to be identified and modified or intervened to generate a healthy learning environment.

Assessment can be understood as an activity that pursues both the result as well as the process of achieving the goal, it monitors the conditions and means of achieving these goals and the activities of the pupil and teacher in the process of achieving goals. School assessment is a process that leads to determining the qualities and achievements showed by a pupil or a group of pupils; it is a systematic activity, i.e. prepared, organised and repeatedly performed, whereby the results are subject to revisions or corrections. Formative assessment is continuous feedback, where the learner obtains information in the learning process that compares the current situation with respect to the starting position and especially to the stated goal. The aim of our research was primarily to identify various forms of assessment at primary school and then to understand how teachers work with formative assessment in teaching practice. In view of the research objectives, a mixed research strategy was chosen. Within the quantitative survey, which focused on the assessment of various forms of assessment at school, a questionnaire of our own construction was used and was administered. The second step was implementing a qualitative survey, where semi-structured interviews were carried out focusing on the issue of format assessment in primary education. Results show that teachers often use alternative forms to the most common (summative) assessment in the form of pupils' portfolio, stamps, stickers, credits or letters. In terms of formative assessment, its contribution to pupils' development is appreciated as well as its greater informative value, but interestingly, many teachers use formative assessment without knowing that the chosen assessment method is known by this term.

Convulsive status epilepticus in children in Mozambique: Is there a treatment gap?
Authors: Sourbron Jo Marie. B. , Lagae Lieven , Sulemane Dalila Ibrahimo
Published: September 2021

Background: Optimal care of Convulsive status epilepticus (CSE) can be related to multiple barriers in resource-limited countries.

Objectives and methods: Since limited data of CSE management are available from South-East Africa, we performed a retrospective analysis of the electronic records of pediatric patients with CSE admitted to the Maputo Central hospital from January 2016 until April 2019.

Results: Our database consisted out of 39 patients. The average age was 5.15 (range 0.3-13.8) years and demographic characteristics did not show a relation to CSE characteristics or outcomes. However, the total stay in the hospital was negatively correlated with age (p=0.0314). Moreover, 14 patients needed to be admitted to the IC, which was correlated to having generalized motor seizures (p=0.0253), and a relatively higher need for a second AED to control their CSE (p=0.0131). Regarding AED use, the first AED was a IV benzodiazepine (BZD: midazolam (MIDA) or diazepam (DIAZ)) or IV phenytoin (PHEN) when BZDs were not available. There was no statistically significant difference between the efficacy of MIDA vs. DIAZ. Eleven patients received PHEN as a second-line drug, of which only two patients needed an additional dose of PHEN. None of the patients died and five patients (13.2%) had an extra comorbidity after CSE.

Conclusions: Although limited AEDs were available in our study, compared to more AEDs in other developing and developed countries, we report the successful cessation of CSE in the majority of cases. We recommend strategies to improve prehospital management such as the use of non-IV BZD use, to limit the need for patients to be admitted to the IC and thereby potentially decreasing the number of AEDs, morbidity and hospital duration. Moreover, our data underline the conversion to second-line AEDs (PHEN) to be adequate in nearly all patients.

The article is devoted to the peculiarities of the communicative activity of younger schoolchildren in the conditions of inclusive education. The article examines the impact of teaching in an inclusive classroom on younger schoolchildren with nor-mative development. The features of the communicative activity of younger school-children in the conditions of inclusive education are determined. For the first time, a comparative study of the components of the structure of the communicative activity of younger schoolchildren was conducted. A comparative analysis of the state of development of communicative skills in ordinary and inclusive classes is carried out, as a result of which it is established that in the conditions of inclusive education there is an intensive development of communicative skills and, accordingly, group cohesion of primary school students. The new information obtained as a result of the empirical research on the peculiarities of the communicative activity of younger schoolchildren with normatypical development in the conditions of inclusive education adds to the knowledge base in the field of pedagogical psychology and can be used by social educators and psychologists of educational institutions in the work on the correction of interpersonal relations in inclusive classes, as well as by students during practical training.
The Problem of Physical Aggression in Adults Diagnosed with Autism in Childhood
Authors: Borodina L.G.
Published: September 2021

In this study, 64 adults originally (in their childhood) diagnosed with autism were examined for hetero-aggression and its character. Physical hetero-aggression was present in roughly one third of the subjects and, at the same time, it turned out to be dependent on the functional and psychopathological levels of the patients. Occurring only occasionally in high and middle functioning adults as part of a psychopathy-like syndrome, aggression was present in most low functioning patients with catatonic symptoms. These motives for aggressive actions have been revealed: gratifying one's aggressive-sadistic impulses, reaction to one's psychological discomfort, provoking a predictable response. In addition to psychological causes of aggression, the parabulia-related component of autistic adults' aggression is discussed together with the relationship between aggression and dysphoric episodes. Families with an aggressive autistic adult were under significant distress. Quite often the aggression led to injuries of the victims, but the families' need for rehabilitation and psychological counselling wasn't satisfied.
The Role of the Psychic Guilt Theory in Establishing Liability in Civil Law
Authors: Monastyrskiy Y.E.
Published: September 2021

The present publication deals with one of the most significant intersections of two social sciences: psychology and civil law, creating both a field of research and a concept such as psychical guilt. It is now a requirement for establishing liability in criminal law and just one of the prerequisites in civil law. However, there is a multitude of guilt theories, all boiling down to two varieties – subjective and objective. At times philosophical and legal ideas resulted in denial of significance of guilt for imposition of material responsibility. The work also raises an issue of the role of psychology as a science in definition of an increasingly important concept of "degree of guilt". This article advocates for the view that in judicial processes, arbitration tribunals, and also in criminal proceedings the most reliable picture of one's psychical attitude should be provided from professional judgement of psychiatrists and psychologists while basing on the entirety of evidence. The research also supports the view of differentiation of the concept of guilt in the criminal and civil-law context. The author is convinced of the necessity of further cooperation of experts in psychology, psychiatry and law.

Published: September 2021

In hernioplasty various grafts are used to close muscular-aponeurotic defects of the abdominal wall of various sizes, as well as to strengthen and replace weak and damaged anatomical gashes. The use of foreign materials for plasty of herniotomy gates often results in infiltrates, suppuration, and ligature fistulas. Extensive suppuration necessitates the removal of grafts (especially synthetic ones), which, as a rule, is complicated by hernia recurrence. In this regard, the advantages of using autografts, especially autodermal flaps due to their great strength, elasticity, resistance to infection are undeniable.

TEMPERATURE-DRIVEN EVAPORATION ANALYSIS OVER BALLIKAYA CATCHMENT
Authors: ELAGCA Adnan , DİŞ Muhammet Ömer
Published: September 2021

Hydrometeorological analysis such as terrain characteristics, flood forecasts and water potentials have become possible through computer models today in parallel with rapidly ever-evolving technology. While the surface-runoff during a storm has linearly and highly correlation with effective precipitation, it is inversely proportional to hydrological losses, including interception, infiltration, transpiration and evaporation. However, flood estimation analysis, in especially rural areas in Turkey, is still not widely and accurately usable, due to difficulties in accessing the necessary ground-based data records such as evaporation, which affects much of the rainfall. Although direct measurement of evaporation is not available now, indirect methods such as evaporation pans have been developed to give acceptable results. On the one hand, observation networks are built by Turkish State Meteorological Service for the estimation of evaporation from open water bodies, these measurements, on the other hand, are only obtained at large climatological stations such as city centers and generally for only six months of the year. In this sense, evaporation values, in order to apply rainfall-runoff analysis, were estimated by Kharrufa, Blaney-Criddle, and modified Blaney-Criddle methods to be used in Monthly Average models. While the highest underestimations were obtained in modified Blaney-Criddle method, Kharrufa method outperformed the other Blaney-Criddle products. The results, confirmed by analysis of the temperature-based Kharrufa approach in two urban areas close to the study basin, show to be appliable for estimation of long-term hydrographs. The analyzed method can be applied over rural watersheds lacking in-situ evaporation measurements as well as enables more accurate rainfall-runoff simulations processes with calibrated and verified hydrological models.

Revisiting the Universal Service Obligation Scheme
Authors: Moorhead Simon
Published: September 2021

In this Journal’s tradition of revisiting past papers which have relevance to today’s events, this article reminds us of the value of the paper “Better telecommunications services for all Australians.” (2015) by Reg Coutts. This paper makes five interrelated recommendations to replace the current Universal Service Obligation (USO) policy in Australia, given the NBN rollout and customer preference for mobile services anywhere anytime.  Some of its recommendations were arguably taken up by the Productivity Commission’s Public Inquiry into the USO in 2016-17, and implemented by the Australian Government in the form of a new Universal Service Guarantee.

Published: September 2021

In this paper, we present simple explicit expressions for single and product moments of generalized order statistics from generalized Pareto distribution. These relations are deduced for the moments of order statistics and record values and tabulated the mean and variance of this distribution. Further, conditional expectation, recurrence relations for single as well as for product moments of generalized order statistics and truncated moment are used to characterize this distribution.

Background: The objectives of this work were to inventory the different morphological entities, to alert the medical class to the need for multidisciplinary care; to sensitize the health authorities on this pathology having a considerable influence on the fertility of the woman and a possible evolution towards cancerous disease.Methods: A retrospective study was carried out over 20 years from January 1983 to December 2002 at the laboratory of anatomy pathology of the faculty of health sciences in Libreville. The revealing clinical signs were the couple's bleeding and infertility. Curettage, endometrial biopsy, and subtotal or total hysterectomy were fixed with 10% buffered formalin or Bouin's fluid. After staining, histological study was carried out by the pathologist.Results: The histological images of the endometrial polyps were the most representative (73 cases or 17.68%), followed by prolonged proliferative endometers (70 cases, or 16.95%), glandulo-cystic hyperplasia (66 cases, or 15.98%) and persistent proliferative endometers (58 cases, or 14.04%). More than half of the numbers concerned women under 35 (225/413 cases); in those over 45 years of age, the predominantly endometrial carcinoma was found. The most affected province was Woleu-Ntem (24%), followed by Haut-Ogooué (18%).Conclusions: The different dysfunctional endometers are also described in the different regions of the continent. The management of these aims to be multidisciplinary and urgently requires a frank collaboration between clinician and morphologist, especially for country where a birth policy is clearly expressed by governing bodies.

Background: Pre-eclampsia is a leading cause of fetomaternal and perinatal morbidity and mortality. The role of serum uric acid (SUA) in determining the complications of preeclampsia has been controversial. This study compared mean SUA levels between severe pre-eclamptics and normotensive women at term and ascertained its correlation with outcomes of preeclampsia; as well as determined if there is a threshold value of SUA level beyond which fetomaternal complications occur.Methods: A case-controlled study where 80 severe pre-eclamptics at term and 80 normotensive women matched for gestational age were recruited. Blood samples were collected from them for assay of SUA levels and they were followed till delivery. The fetomaternal outcomes and the corresponding SUA levels at diagnosis were documented and variables statistically analyzed. A receiver operating characteristic curve was used to determine the cut-off value of SUA beyond which adverse fetomateral complications are likely to occur in pre-eclampsia.Results: The mean SUA level in severe pre-eclamptics (0.283±0.09 mmol/l) was not significantly higher than that of normotensive women (0.263±0.09 mmol/l, p=0.13). There was a weak positive correlation between the SUA levels and fetomaternal outcomes [maternal (r=0.102, p=0.236) and fetal (r=0.096, p=0.226)]. The study was unable to identify the threshold SUA level at which adverse fetomaternal outcomes occur as the values of SUA were closely related.Conclusions: SUA levels of pre-eclamptics and normotensive women did not show significant difference and correlated weakly with fetomaternal outcomes and are therefore poor predictor of fetomaternal outcomes in pre-eclampsia.

Background: Floods are an important source of infection epidemic worldwide. Analysis of different infections presenting during floods can lead us to have a unified approach during such periods.Methods: This study describes the clinical features of fever patients presented to a tertiary care hospital in Kerala after the 2018 flood. Clinical findings of the confirmed leptospirosis cases were also compared with non-leptospirosis cases.Results: A total of 48 patients with fever and myalgia were studied and majority of them were males (77%). 40 patients had contact with contaminated water. But only 10 of them had taken prophylactic doxycycline. Complications were seen less among those who took prophylactic doxycycline. The mean time from the first symptom to first medical care was 4.4 days. Leptospirosis was seen among 15 patients and 2 patients had dengue fever. Hepatic involvement and renal involvement were seen significantly higher among leptospirosis patients.Conclusions: This study emphasized the importance of prophylactic doxycycline and early initiation of antibiotics during flood outbreaks. Awareness among treating doctors and patients is required for the control of outbreaks and prevention of mortality during floods.

Published: September 2021

Background: Modified radical mastectomy (MRM) is the most common surgery for cancer breast that is associated with marked postoperative pain. Effective control of this pain suppresses the surgical stress response and decreases the need for opioids and general anesthetics. This study was aimed to compare ultrasound guided erector spinae block (US-ESP) with modified pectoralis nerve block (US-PECS) in terms of post-operative pain scores as the primary objective, in patients undergoing MRM. The secondary objectives of our study were to compare the time of first rescue analgesic, total analgesic consumption and side-effects between the two groups.Methods: Group E comprised of patients receiving 20 mL of 0.2% ropivacaine plus 0.5 µ/kg dexmedetomidine and it was injected in‑between erector spinae muscle and transverse process. Group P comprised of patients receiving 30 mL of 0.2% ropivacaine plus 0.5 µg/kg dexmedetomidine divided into 10 mL that was injected between the two pectoralis muscles in the inter-fascial plane and the remaining 20 mL was injected between the serratus anterior and the pectoralis minor muscle.Results: Demographic profile was comparable between both groups. Both groups offered good analgesia, but PECS group took an upper hand up to the 6th post-operative hour (p<0.05). Beyond the 6th post-operative hour, analgesic efficacy of both groups was comparableConclusions: Modified pectoralis nerve block offered better analgesia over the erector spinae block technique up to 6th post-operative hour and it is more effective in terms of total rescue analgesic consumption and the time for request of first rescue analgesic, in patients posted for MRM.
