The impact of heterogeneous environmental regulations on the technology innovation of urban green energy: a study based on the panel threshold model
Authors: Xu Xueying , Hou Peng , Liu Yue
Published: March 2022

Since the Porter hypothesis was proposed, environmental regulation has been recognized as a critical factor influencing technology innovation. However, there is no unified conclusion on whether the relationship between the two is linear or non-linear, and environmental regulation is always examined from single angles. Therefore, according to the difference of environmental regulation implementation subjects, this paper divides environmental regulation into formal regulation and informal regulation. Utilizing the panel data of 281 prefecture-level and above cities in China from 2011-2019, the non-linear effects of heterogeneous environmental regulations on green energy technology innovation are analyzed based on the panel threshold model, and the non-linear relationship between the two under the difference in urban economic development level is further considered. The results indicate that: (1) The threshold effect of the environmental regulations on China's green energy technology innovation is significant, and there is heterogeneity in the effects of different environmental regulations. (2) At present, positive relationship are observed between the informal environmental regulation and green energy technology innovation in China, while the formal environmental regulation exerts a significant inhibitory effect on green energy technology innovation. (3) The level of regional economic development plays a significantly positive role in moderating the relationship between environmental regulation and green energy innovation. However, there exists a certain heterogeneity in the moderating role between the formal regulation-innovation link and informal regulation-innovation relationship. This study provides a reference for further clarifying the relationship between heterogeneous environmental regulations and green energy technology innovation.

The bond incident degree (BID) index of a graph $ G $ is defined as $ BID_{f}(G) = \sum_{uv\in E(G)}f(d(u), d(v)) $, where $ d(u) $ is the degree of a vertex $ u $ and $ f $ is a non-negative real valued symmetric function of two variables. A graph is stepwise irregular if the degrees of any two of its adjacent vertices differ by exactly one. In this paper, we give a sharp upper bound on the maximum degree of stepwise irregular graphs of order $ n $ when $ n\equiv 2({\rm{mod}}\;4) $, and we give upper bounds on $ BID_{f} $ index in terms of the order $ n $ and the maximum degree $ \Delta $. Moreover, we completely characterize the extremal stepwise irregular graphs of order $ n $ with respect to $ BID_{f} $.

Authors: Li Hui ,   Department of Computer Science and Technology, Beijing University of Chemical Technology, Beijing 100029, China, Zhang Mengyao , Zeng Chenbo
Published: March 2022

Traveling salesman problem is a widely studied NP-hard problem in the field of combinatorial optimization. Many and various heuristics and approximation algorithms have been developed to address the problem. However, few studies were conducted on the multi-solution optimization for traveling salesman problem so far. In this article, we propose a circular Jaccard distance based multi-solution optimization (CJD-MSO) algorithm based on ant colony optimization to find multiple solutions for the traveling salesman problem. The CJD-MSO algorithm incorporates "distancing" niching technique with circular Jaccard distance metric which are both proposed in this paper for the first time. Experimental results verify that the proposed algorithm achieves good performance on both quality and diversity of the optimal solutions.
Education program on medical error disclosure for emergency medicine residents using standardized patients
Authors: Kim Chanwoong , Park Kyung Hye , Eo Eun Kyung
Published: March 2022

Purpose: We aimed to develop a program for error disclosure for emergency medicine (EM) residents to determine its effects.Methods: Fifteen EM residents participated in 2020. The program included two-error disclosure sessions using standardized patients (SPs), a didactic lecture, and debriefing. The Kirkpatrick model was used to evaluate this program. Satisfaction scores and narrative reactions were collected (level 1). Residents were asked to choose their actions and explain reasons for the representative error cases before and after the program (level 2). After 2 months, they were asked to write their experiences of disclosing errors to real patients (level 3). The differences in the disclosing communication scores allocated by the SPs were compared between the senior and junior residents.Results: The residents’ satisfaction scores were high. Before the program, some residents chose not to disclose errors when there were no harmful sequelae at the time of the incident. After the program, opinions changed, and the residents thought that all errors should be disclosed. Before the program, most residents disclosed the errors to patients first; after the program, they would report to the hospital first to receive guidance. After 2 months, five residents reported disclosing errors to real patients. The senior residents’ total scores and the scores for “prevention of future errors” were higher.Conclusion: The residents showed confidence in error disclosure while maintaining rapport with the real patient, and some were satisfied with their disclosure approach. Our error disclosure program for EM residents had a positive effect on their behavior and attitude toward error disclosure.
Strategies for developing pre-clinical medical students’ clinical reasoning based on illness script formation: a systematic review
Authors: Si Jihyun
Published: March 2022

Clinical reasoning training in the pre-clinical phase has recently been considered important; however, when it comes to specific instructional methods for pre-clinical students, much is unknown. Thus, the aim of this review is to explore learning and teaching methods for pre-clinical students’ clinical reasoning development based on illness script formation, their results, and strategies. A systematic review was conducted in accordance with the guidelines of the Association for Medical Education in Europe. The literature search was performed using the Cochrane Library, PubMed, EMBASE, Web of Science, and ERIC databases based on keywords, including “illness script*” AND (“medical student*” OR pre-clinical OR undergraduate). Then, 10 studies among the 91 studies were included in the final analysis. The quality of the selected studies was also appraised using the Medical Education Research Study Quality Instrument. Diverse teaching and learning methods were used to support the integration of biomedical and clinical knowledge working with patient cases, and their effects were assessed through diverse methods, including illness script richness and maturity, to learner responses. The effects of these interventions were effective in terms of the clinical reasoning development of pre-clinical students. Learning and teaching strategies were synthesized and described. This review found that explicit attempts to promote illness script formation with a structured program rather than informal training lead to positive results, and such formal clinical reasoning programs can provide smooth transition from pre-clinical to clinical experience.

Published: March 2022

Z raziskavo vodnoekoloških razmer na območju doline Zaloka leta 2020 smo sledili predhodni terenski študiji iz leta 1978. Zajeto je bilo isto območje, ki je bilo prvotno preučeno kot potencialno območje zajema pitne vode, danes pa je vključeno v komunalno oskrbo s pitno vodo za več kot 30.000 ljudi. Na podlagi fizikalno-kemijskih kazalnikov posameznih vodnih virov in podnebno-geoloških značilnosti območja smo ohranjanje dobrega vodnoekološkega stanja preučenih vodnih virov povezali s padavinskimi in hidrogeografskimi razmerami širšega območja izvira Ljubija. Nizka vsebnost nitratov in majhna nihanja tudi ostalih parametrov kažejo na majhen vpliv človeka.

The year 2020 water-ecological research followed the preliminary field study from 1978. We covered the same area of the Zaloka Valley, which was originally explored as a potential drinking water area, but today is included in municipal drinking water supply for more than 30,000 people. Based on physical-chemical indicators of individual water sources and climate-geological characteristics of the area, we associated the maintenance of good water-ecological status of the studied water sources with precipitation and hydrogeographic features of the wider area of the Ljubija karst spring. The low nitrate content and small fluctuations in other parameters describe the study area as an area with low human impact.
Student Use of Learning Management Systems in the Private Sector of New Zealand Higher Education
Authors: Shaheen Zarqa
Published: March 2022

The purpose of this research project was to measure the effects of the perceptions that students hold of the functionality of LMS and students’ self-efficacy specific to using LMS in their studies on student LMS acceptance and use. The theoretical framework of the study is based on the Technology Acceptance Model (TAM), into which perceived functionality and LMS self-efficacy were incorporated as external variables. A web-based questionnaire was administered to students in a private higher education institution in Auckland, New Zealand. These responses were analyzed using Pearson’s correlation and linear regression. The results indicated that perceived functionality significantly influenced perceived usefulness. Similarly, it was found that LMS self-efficacy significantly influenced perceived ease of use. However, no evidence was found that attitudes towards using LMS predicted behavioural intention to use.

Authors: Shanmugasundaram Kumar , Talwar Anjana , Madan Karan , Bade Geetanjali
Published: March 2022

Background: Post-tuberculosis (TB) sequelae is a commonly encountered clinical entity, especially in high TB burden countries. This may represent chronic anatomic sequelae of previously treated TB, with frequent symptomatic presentation. This pilot study was aimed to investigate the pulmonary functions and systemic inflammatory markers in patients with post-TB sequelae (PTBS) and to compare them with post-TB without sequelae (PTBWS) participants and healthy controls.Methods: A total of 30 participants were enrolled, PTBS (n=10), PTBWS (n=10), and healthy controls (n=10). Pulmonary function tests included spirometry and measurement of airway impedance by impulse oscillometry. Serum levels of matrix metalloproteinase (MMP)-1, transforming growth factor-β, and interferon-γ were estimated.Results: Slow vital capacity (SVC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC, and peak expiratory flow were significantly lower in PTBS as compared to controls. SVC and FEV1 were significantly less in PTBS as compared to PTBWS. Total airway impedance (Z5), total airway resistance (R5), central airway resistance (R20), area of reactance (Ax), and resonant frequency (Fres) were significantly higher and respiratory reactance at 5 and 20 Hz (X5, X20) were significantly lower in PTBS as compared to PTBWS. Spirometry parameters correlated with impulse oscillometry parameters in PTBS. Serum MMP-1 level was significantly higher in PTBS as compared to other groups.Conclusion: Significant pulmonary function impairment was observed in PTBS, and raised serum MMP-1 levels compared with PTBWS and healthy controls. Follow-up pulmonary function testing is recommended after treatment of TB for early diagnosis and treatment of PTBS.
A Turbulence Model for Flight Simulation and Handling Qualities Analysis Based on a Synthetic Eddy Method
Authors: Henriquez Huecas Sergio , White Mark D. , Barakos George
Published: March 2022

A turbulence model based on a synthetic eddy method (SEM) has been adapted for flight simulation purposes and coupled with a FLIGHTLAB helicopter simulation model. The SEM is based on the generation of a random distribution of turbulence-generating eddies within a control volume surrounding
the simulated aircraft. Eddies are displaced by the flow and regenerated at the inflow as they leave the simulation domain. The model allows adjustment of turbulence intensity and frequency spectra, allowing for a more realistic representation of broadband turbulence. Compared to other random
turbulence models, preserving the location of the eddies in the control volume automatically ensures that turbulence across different aircraft locations is automatically correlated. Off-line and piloted flight simulation assessments have been conducted to test the viability of the SEM concept
in flight simulation. Results show that the turbulence model generates upsets in all aircraft axes resulting in higher workload requirements for the pilot.
Assessing therapist and clinician competency in parent-infant psychotherapy: The REARING coding system (RCS) for the group attachment based intervention (GABI)
Authors: Armusewicz Kelsey , Steele Miriam , Steele Howard , Murphy Anne
Published: March 2022

The development of fidelity and quality measures for the dissemination of evidence-based practices is an often-neglected, vital step in the implementation of psychological interventions, especially within parent-infant mental health. The current study aims to address this gap by developing a competency-based measure for clinicians delivering the Group Attachment Based Intervention (GABI). GABI is an intervention aimed at supporting family preservation in parents who have experienced disparities across multiple systems of care. After observing over 100 hours of clinical video, the research team, comprised of clinicians and academic researchers, developed a competency coding system to measure clinician efficacy titled the REARING coding system (RCS). This paper outlines the development and structure of the measure, including a detailed discussion of the model of therapeutic action (i.e., REARING: reflective functioning, emotional attunement, affect regulation, reticence, intergenerational transmission of attachment, nurturance, and group therapy context), as well as provides a clinical case study to illustrate the utility, flexibility, and depth of the measure. The case study details a family session consisting of a mother, father, and two children (one infant, one toddler), and how RCS can be used in supervision to foster clinical competency and effectiveness in the GABI model. RCS seeks to address the dissemination gap in Evidence Based Practices (EBPs) by contributing to the limited number of existing fidelity and competency measures in infant mental health and psychodynamic dyadic psychotherapy. RCS is an important tool for monitoring clinical competency in the dissemination of GABI and gives supervisors the ability to provide fidelity-focused supervisions.

Published: March 2022

The reliable clinical-diagnostic evaluation of child patients is crucial. The present research sought to examine the validity of the Psychodiagnostic Chart-Child (PDC-C) in assessing children’s mental functioning and personality organization, according to the framework of the Psychodynamic Diagnostic Manual, Second Edition (PDM-2). A sample of 209 clinicians assessed 209 children (aged 4-11 years) who had been in their care between 2-12 months, using the PDC-C. Each clinician also completed a clinical questionnaire to provide demographic information, the Child Behavior Checklist to evaluate children’s behavioral problems and social competences, and the Childhood Personality Assessment Q-Sort measure to assess children’s emerging personality patterns. The findings suggest that the PDC-C is a valid diagnostic tool that considers children’s full range of functioning. Moreover, the measure has good sensitivity and appears clinically useful in differentiating between certain clinical populations according to psychological characteristics. The PDC-C could promote more accurate assessment during childhood and inform the development of individualized therapies. One of the advantages of the tool is its ability to capture individual variations in child functioning (illuminating strengths and psychological vulnerabilities), even within children in the same diagnostic group. Of note, additional research is needed to establish the utility of PDC-C ratings in predicting clinically relevant constructs and to monitor the processes and outcomes of interventions.

Published: March 2022

Background: We evaluated the achievement of low-density lipoprotein cholesterol (LDL-C) targets in patients with type 2 diabetes mellitus (T2DM) according to up-to-date Korean Diabetes Association (KDA), European Society of Cardiology (ESC)/European Atherosclerosis Society (EAS), and American Diabetes Association (ADA) guidelines.Methods: This retrospective cohort study collected electronic medical record data from patients with T2DM (≥20 years) managed by endocrinologists from 15 hospitals in Korea (January to December 2019). Patients were categorized according to guidelines to assess LDL-C target achievement. KDA (2019): Very High-I (atherosclerotic cardiovascular disease [ASCVD]) <70 mg/dL; Very High-II (target organ damage [TOD], or cardiovascular risk factors [CVRFs]) <70 mg/dL; high (others) <100 mg/dL. ESC/EAS (2019): Very High-I (ASCVD): <55 mg/dL; Very High-II (TOD or ≥3-CVRF) <55 mg/dL; high (diabetes ≥10 years without TOD plus any CVRF) <70 mg/dL; moderate (diabetes <10 years without CVRF) <100 mg/dL. ADA (2019): Very High-I (ASCVD); Very High-II (age ≥40+ TOD, or any CVRF), for high intensity statin or statin combined with ezetimibe.Results: Among 2,000 T2DM patients (mean age 62.6 years; male 55.9%; mean glycosylated hemoglobin 7.2%) ASCVD prevalence was 24.7%. Of 1,455 (72.8%) patients treated with statins, 73.9% received monotherapy. According to KDA guidelines, LDL-C target achievement rates were 55.2% in Very High-I and 34.9% in Very High-II patients. With ESC/EAS guidelines, target attainment rates were 26.6% in Very High-I, 15.7% in Very High-II, and 25.9% in high risk patients. Based on ADA guidelines, most patients (78.9%) were very-high risk; however, only 15.5% received high-intensity statin or combination therapy.Conclusion: According to current dyslipidemia management guidelines, LDL-C goal achievement remains suboptimal in Korean patients with T2DM.
The necessity and appropriate range of the diagnostic “gray zone” of 13C-urea breath test
Authors: Yin Zhihao , Xiao Shiyu , Tian Xueli , Yuan Ziying , Zhou Liya
Published: March 2022

Background:

The 13C-urea breath test (13C-UBT) is preferred for non-invasive detection of Helicobacter pylori (H. pylori); however, its accuracy drops when results fall between 2‰ and 6‰ (called the gray zone). This study aimed to evaluate the accuracy of 13C-UBT (cut-off point 4‰) between 2‰ and 6‰, find a more appropriate gray zone, and identify the factors influencing 13C-UBT.

Methods:

Patients with 13C-UBT results 2‰–6‰, over an eight-year period, were studied. H. pylori infection was diagnosed if patients were positive for either Warthin–Starry staining or quantitative real-time polymerase chain reaction (real-time PCR), and excluded if both were negative. Accuracy of 13C-UBT under different cut-off points was calculated, and the factors affecting 13C-UBT were analyzed.

Results:

A total of 208 patients were included, of whom 129 were H. pylori–positive. Sensitivity, specificity, negative predictive value (NPV), and positive predictive value (PPV) of 13C-UBT were 71.32%, 83.54%, 64.08%, and 87.62%, respectively. When the cut-off point was changed to 2.15‰, the NPV of 13C-UBT reached a maximum (76.47%); when the cut-off point was changed to 4.95‰, PPV reached its maximum (93.22%). Therefore, the original gray zone (2‰–6‰) was adjusted to 2‰–4.95‰. Gastric antral intestinal metaplasia (OR = 3.055, 95% CI: 1.003–9.309) was an independent risk factor for false-negative 13C-UBT.

Conclusions:

Accuracy of 13C-UBT over 2‰–6‰ was poor, and the gray zone was changed to 2‰–4.95‰. 13C-UBT results over 2‰–4.95‰ should be interpreted with caution during mass screening of H. pylori, especially for patients with gastric antral intestinal metaplasia.

Authors: Alhammad Abdulaziz Saad , Mulafikh Dhaifallah S. , Alsaleh Saad A.
Published: March 2022

Context:

The novel coronavirus disease (COVID-19) has swept globally, leading to a crisis that affects all aspects of human life.

Aims:

This study aimed to investigate the impact of COVID-19 on otolaryngology-head-and-neck surgery (ORL-HNS) residency training in Saudi Arabia and assess the study habits of residents during the pandemic and the impact of COVID-19 on training.

Settings and Design:

This was a cross-sectional quantitative study that utilized a 36-item questionnaire, investigating demographic data, study habits during the pandemic, clinical involvement in various training domains before and during the pandemic, and COVID-19-related exposure and training.

Subjects and Methods:

The questionnaire was sent to all ORL-HNS residents in Saudi Arabia via email, except those in their first year of residency.

Statistical Analysis Used:

A Wilcoxon signed-rank test was performed to assess the difference in clinical involvement before and during the pandemic.

Results:

A total of 165 residents participated in this study (response rate = 72.7%). A statistically significant decrease in clinical involvement from before to during the pandemic was noted in all training domains, including the average number of emergency consultations during on-call duty, outpatient clinics, in-office diagnostic procedures, and operative procedures for oto-neurotology, rhinology and skull base, head and neck, pediatric and airway, and facial plastic. However, an increase in the consultation via telemedicine was apparent during the pandemic in comparison to before.

Conclusion:

The COVID-19 pandemic has affected ORL-HNS residency training considerably. We recommend implementing alternative didactic strategies to mitigate the decreased exposure of residents to ORL-HNS clinical training.
Single Versus Multiple Mini-tract Percutaneous Nephrolithotomy for Staghorn Renal Stone
Authors: Tsai I-Chen , Chen Zhi-Hao , Lee Kau-Han , Liu Chien-Liang , Huang Steven K. , Chiu Allen W.
Published: March 2022

Purpose:

Percutaneous nephrolithotomy (PCNL) is the standard procedure used for large kidney stones, and multiple tracts of PCNL are applied to achieve better stone clearance. However, the creation of multiple tracts may have the potential risk of bleeding and higher complication rates compared with single-tract procedures. We reviewed our experience managing staghorn calculi with multiple tracts compared with a single tract.

Materials and Methods:

Records of 36 patients with staghorn calculi who underwent PCNL at our institution between January 2018 and April 2020 were reviewed retrospectively. Nineteen patients were managed by single-tract access (Group 1), and 17 patients underwent multiple-tract access (Group 2). Both groups were compared in terms of perioperative findings and postoperative outcomes.

Results:

The mean number of percutaneous accesses in the multiple-tract group was 2.88, with most patients requiring two tracts. The mean duration of fluoroscopy screening and operative time was longer in Group 2. Stone-free rates were 59% and 70.5% in Groups 1 and 2, respectively. The mean hospital stay was similar in both groups. Complications included blood transfusion, resulting from a hemoglobin drop of 2.15 ± 0.96 and 1.59 ± 0.69 g/dL in Groups 1 and 2, respectively. Mean pre- and post-operative creatinine concentrations were 1.212 and 1.211 mg/dL in Group 1 and 1.206 and 1.157 mg/dL in Group 2. Mean changes in creatinine values were not statistically significant between the groups. Clavien–Dindo Classification Grade II complications included urosepsis and blood transfusion, which occurred in five patients in Group 1 and three in Group 2. Pseudoaneurysm attributed to Grade III complications occurred in one patient in Group 1.

Conclusion:

Multiple-tract access during PCNL is a safe and efficient method to manipulate staghorn kidney stones. Mini PCNL with multiple-tract access is a successful alternative to deal with staghorn stones involving multiple calyces.

Published: March 2022

Purpose:

This study evaluated the effectiveness and safety of transperitoneal laparoscopic ureterolithotomy (TPLU) and retroperitoneal laparoscopic ureterolithotomy (RPLU) in the surgical management of ureterolithiasis.

Materials and Methods:

The current prospective study was conducted at the Department of Urology, Dr. D. Y. Patil Medical College. The complete patient medical history including patient's age, sex, stone (size, number, and laterality), and past history of stone surgeries were evaluated. Based on the treatment method, the patients were divided into TPLU and RPLU group. Both the procedures were evaluated for parameters including operative technique, operating time, hospital stay, intra- and postoperative complications, conversion rate, success rate, and surgical ergonomics.

Results:

A total of 50 patients were included (TPLU, n = 25; and RPLU, n = 25). The average age was 43.6 years in the TPLU and 46.7 years in the RPLU group. The average size of calculi was >15 mm in both the groups. The operation time and blood loss were relatively higher in the TPLU group than RPLU group. The complete stone clearance was observed in both the groups. The pain in loin area and burning micturition were the most common complaints reported by the patients from both the groups. One patient from RPLU group was converted to open surgery. The calculi size in TPLU group was positively correlated with operative time (r = 0.535, P = 0.006), blood loss (r = 0.440, P = 0.028), and hospital stay (r = 0.430, P = 0.032).

Conclusion:

TPLU and RPLU are feasible techniques for the management of large ureteric stones that are not amenable to ureteroscopy or extracorporeal shockwave therapy.

Purpose Plasma circulating tumor DNA (ctDNA) could reflect the genetic alterations present in tumor tissues. However, there is little information about the clinical relevance of cell-free DNA genotyping in peripheral T-cell lymphoma (PTCL).Materials and Methods After targeted sequencing plasma cell-free DNA of patients with various subtypes of PTCL (n=94), we analyzed the mutation profiles of plasma ctDNA samples and their predictive value of dynamic ctDNA monitoring for treatment outcomes.Results Plasma ctDNA mutations were detected in 53 patients (56%, 53/94), and the detection rate of somatic mutations was highest in angioimmunoblastic T-cell lymphoma (24/31, 77%) and PTCL, not otherwise specified (18/29, 62.1%). Somatic mutations were detected in 51 of 66 genes that were sequenced, including the following top 10 ranked genes: RHOA, CREBBP, KMT2D, TP53, IDH2, ALK, MEF2B, SOCS1, CARD11, and KRAS. In the longitudinal assessment of ctDNA mutation, the difference in ctDNA mutation volume after treatment showed a significant correlation with disease relapse or progression. Thus, a ≥ 1.5-log decrease in genome equivalent (GE) between baseline and the end of treatment showed a significant association with better survival outcomes than a < 1.5-log decrease in GE.Conclusion Our results suggest the clinical relevance of plasma ctDNA analysis in patients with PTCL. However, our findings should be validated by a subsequent study with a larger study population and using a broader gene panel.
Topology of leaves for minimal laminations by non-simply-connected hyperbolic surfaces
Authors: Alvarez Sébastien , Brum Joaquín
Published: March 2022

We give the topological obstructions to be a leaf in a minimal lamination by hyperbolic surfaces whose generic leaf is homeomorphic to a Cantor tree. Then, we show that all allowed topological types can be simultaneously embedded in the same lamination. This result, together with results in [arXiv:1906.10029] and [Comment. Math. Helv. 78 (2003), 845–864], completes the panorama of understanding which topological surfaces can be leaves in minimal hyperbolic surface laminations when the topology of the generic leaf is given. In all cases, all possible topologies can be realized simultaneously.

A method is proposed and a technique is developed for accelerated bench tests in laboratory conditions of knives of cutting-reducing devices of forage harvesters. One of the main purposes of the developed method is an experimental comparative assessment of the long-term performance (according to the wear resistance criterion) of various knife options (according to the materials for their manufacture and structural and geometric parameters). The proposed test method solves the problem of assessing the wear resistance of agricultural harvester knives by two parameters: physical depreciation and dulling of their cutting edge. A flexible belt with an abrasive fixed on one of its surfaces is used as counter-specimens during testing, which allows for wear with sliding impact and thereby significantly accelerates the process of knives damage. The technique makes it possible to test simultaneously two knives made using different technologies, under comparable conditions. In addition, to speed up testing, not one, but several counter-specimens are mounted on the test equipment. As a result of such tests, the process of impact-fatigue loading with slipping is simulated and the damage to the knife is reproduced, which is close to the operational one: wear and an increase in the cutting edge radius. Using the developed technique, comparative accelerated tests of imported steel and domestic cast iron (produced by OJSC “Gomselmash”) knives made using various technologies were carried out. The tests conducted made it possible to quantify the difference in the service characteristics of the cutting drum knives made using various technologies, which confirms its usefulness and efficiency. The developed technique was approved in accordance with the established procedure and is used for bench testing of knives at OJSC “Gomselmash”.

The present study was conducted to understand the relationship between Researcher-like disposition and teaching effectiveness of teacher educators in two phases. The first Phase was the quantitative Phase, in which Pearson product-moment correlation was carried out to understand the relationship between the variables. One hundred teacher educators are teaching B.Ed. A stratified sampling technique selected the course. The second Phase was the qualitative Phase, in which only 20 teacher educators were randomly selected and interviewed to understand the problems faced by teacher educators in teaching & conducting research. The present study's findings revealed a significant and positive relationship between researcher-like disposition and teaching effectiveness of teacher educators, and the researcher-like disposition has positively contributed to enhancing the teaching effectiveness of teacher educators (p<0.01 level). However, the findings also revealed that the teaching workload, inadequate research pre-service training, infrastructure constraints, Lack of training in ICT, and involvement in other administrative work were the various factors affecting teaching effectiveness and research performance. In a rapidly changing teaching and learning scenario, conducting research is one of the most potential approaches and thoughtful ways to inspire, motivate, and equip teacher educators with skills to teach evidence-based methods. The result of the present study provides a clear picture to the educationists and policymakers to improve the teaching effectiveness and research performance of teacher educators teaching in B.Ed.

Published: March 2022

El objetivo de la investigación fue comprender el proceso de educación virtual en tiempos de pandemia de la Universidad Técnica de Manabí, desarrollada con el paradigma interpretativo, enfoque cualitativo, método fenomenológico hermenéutico. Los hallazgos ofrecen  doce categorías distribuidas en tres bloques que expresan los momentos en que emerge el fenómeno. Se concluyó que la emigración de los procesos pedagógicos a los entornos virtuales altera la vida de los estudiantes, originando conductas disruptivas por la carencia de recursos tecnológicos y económicos, hecho que los desmotiva e induce a abandonar los estudios.

RIGIDIZATION OF MENTAL IMAGES AS DYSFUNCTION OF PICTURES RECOGNITION
Authors: Hovhannisyan H. R. , Manukyan A. A.
Published: March 2022

This article illustrates the unique effect of human visual perception: during the recognition of images specially distorted by a computer program, the subject spontaneously “creates and strengthens” the imaginary contours of the presented stimulus material. Piloting experimentally, we found that sometimes during the observation of the process of gradual clarification of completely distorted pictures, 50 the recognition by the subjects is complicated, because the signs of a previously fancied imaginary contour are enhanced. The observer seemed to be “under the influence of an fancy imaginative scenario”, as a result of which the “contour attribution” retained its increasing power, thereby making the mental image rigid. As a result, the recognition function of the gradually becoming clearer image was temporarily blocked (disordered).
