Preanalytical features of the determination of circulating microRNAs as new specific biomarkers of the body’s response to physical activity
Authors: Postnikov P. V. , Pronina I. V.
Published: May 2022

MicroRNAs are small non-coding single-stranded RNAs, 18 to 25 nucleotides long, they regulate gene expression at the post-transcriptional level through specific binding to the target mRNA, leading to its degradation. In recent decades, the development of technologies for determining the expression profiles of miRNAs has become an important part of research projects, and the role of miRNAs as potential highly informative molecular biomarkers of various physiological and pathological processes in the body is actively explored by the scientific community. In particular, physical activity is an important modifying factor for circulating miRNAs. Unlike classical blood biochemical parameters, which can change over time depending on the temperature and storage conditions of the sample, microRNAs remain stable during storage and even after multiple freeze-thaw cycles, which makes them an attractive and easily accessible target for detection. However, the determination of the microRNA expression profile in clinical practice is still difficult due to the high heterogeneity of analytical procedures used for testing. In sports medicine, the preanalytical stage is especially important, since often the conditions for sampling are not standardized and can affect the analysis result. This review shows the role of miRNAs as new sensitive biomarkers of the effectiveness of the training process and regulators of the body’s response to physical activity, and also discusses some preanalytical aspects of the analysis of miRNA expression profiles.

The purpose of the study is to determine the effectiveness of the specialized product Fit Tonus for correcting the psychophysiological state and neuromuscular transmission in highly qualified athletes.

Materials and methods: the objects of research were: specialized product of sports nutrition for correcting the psychophysiological state and neuromuscular transmission Fit Tonus; 21 male martial arts athletes aged 14 to 25 years. The researches were carried out in accordance with official and conventional techniques. Body temperature, breathing rate, blood pressure level, heart rate was determined, heart rate variability, ECG, external breathing, O2 intake, total urine test, clinical blood test, biochemical blood indices were evaluated, water sectors of the body, body skinny weight, body fat weight were determined. Full-function cardiopulmonary analysis was performed using the Meta Lyzer 3B inpatient cardio-respiratory loading diagnostic system (Cortex Medical, Germany). Maximum oxygen consumption was determined by a Cosomed metabolograph (Italy). Biochemical parameters (bilirubin, ACT, ALT, urea, uric acid, glucose, cholesterol, HGT, amylase, alkaline phosphatase, creatinine) were examined on a Humalyzer biochemical analyzer. Water sectors of the body, the value of skinny body weight and fat body weight were determined on an analyzer for assessing the balance of water sectors of the body (Medass, Russia).

Results: in the analysis of biochemical blood values, the blood levels of indicator enzymes and their isoforms were normalized in a short time, despite high training loads. This fact reflects the adaptation of the athlete’s body to high-intensity physical activity when taking the Fit Tone product. The obtained results of the increase in GUS, FFV and Tiffno test indicate an increase in both functional capabilities and functional abilities of the external breathing system, as well as an increase in the efficiency of the respiratory center in athletes who received the tested product. The effectiveness of the test product is confirmed by the results of dynamic and stress samples in a stabilometric study. Results of examination of psychophysical status of single wrestlers showed that during usage of developed product such indicators as performance, vegetative coefficient, dynamism, speed of movement, accuracy of actions, stability of actions are significantly increased. At the same time, the level of fatigue and anxiety is reliably reduced.

Conclusions: the results of the researches performed showed that the product developed demonstrated efficacy for most of the parameters under research in the main group compared to the control (placebo).

Social Sciences (IPS) is a subject that discusses problems/cases of how students live socially, as a nation and as a state. The learning process should ideally prioritize the active involvement of students in interacting with learning resources and materials. Students must always be trained to think critically to solve problems, cooperate and establish active communication between students and teachers as learning facilitators. One alternative learning that is currently becoming a phenomenal that is growing in the world of education is participatory learning. The principle of participatory learning is that students have learning needs, understand learning techniques and learn behavior.

 

To achieve maximum learning outcomes, the author tries to change the learning method with discussion techniques. In this case the author uses the Jigsaw comparative learning model. The application of this discussion technique is a participatory learning technique, aimed at training students to communicate actively with fellow learners so that the learning environment becomes more lively and passionate.

Apart from being a pillar/element in Contextual Teaching and Learning, the group discussion learning strategy is an alternative learning model that can be used to maximize student involvement through solving cases/problems that are in accordance with the basic competencies that must be mastered by students.

A Krím félsziget annektálásának orosz költségei és a folyamat visszafordíthatóságának kérdése
Authors: Andrékó Gábor
Published: May 2022

Ukrán részről a terület elvesztése traumát okozott, de töretlenül reménykednek abban, hogy a Krím félsziget elszakadásának a folyamata megállítható és visszafordítható. A kutatás arra fókuszál, hogy a félsziget Ukrajnához történő visszatérésének milyen realitása van az USA új külpolitikai prioritásai és a nemzetközi jog alapján, továbbá az orosz gazdasági, pénzügyi és infrastrukturális beruházások, illetve az orosz és a külföldi tőkebefektetések tükrében. A cikk kiemelten vizsgálja a Krímnek az Oroszországhoz csatolása utáni orosz állami reakciókat, különösen a meghozott intézkedések tartalmát, céljait és a pénzügyi befektetések nagyságát. Áttekinti az orosz és a külföldi eredetű befektetésekkel kapcsolatos kérdéseket, amelyek jelentőségét az adja, hogy áttételesen, a gazdasági érdekek előtérbe kerülésével erősíthetik meg a Krímnek az orosz területként történő nemzetközi elismertetését. A kutatás hipotézise, hogy a Krím elcsatolása egy végérvényesen lezárult folyamat, és bár a Huntington által kifejtett civilizációs törés nincs a két ország között, sőt rokon nemzetek közötti vitáról van szó, a terület Ukrajnához való visszatérése reálisan mégsem várható.

Introduction: COVID-19 affects the liver, causing alteration in liver biochemistry tests such as aspartate transferase (AST), alanine transferase (ALT), alkaline phosphatase (ALP), total bilirubin and albumin. Objective: To determine the prevalence of alteration in liver functions tests and associated factors for severity among Peruvian COVID-19 patients. Materials and methods: A descriptive, retrospective and cross-sectional study was performed in 4 public hospitals in Peru. Patients admitted to hospitalization wards and intensive care units with a diagnosis COVID-19 were enrolled. The evaluation of AST, ALT, ALP, total bilirubin and albumin was performed. Associations with demographic and medical data were assessed. Results: 1,100 patients were enrolled, of which 81.7% had altered liver function tests. Only 2.8% of the patients had cirrhosis and 2.1% hepatitis B/C virus. AST and ALT were altered at admission in 64.7% and 63.7%, of the patients respectively. Factors associated with liver injury were: being female OR=0.53 (95% CI: 0.39-0.73; p<0.01), dyslipidemia OR=1.72 (95% CI: 1.10-2.70; p=0.01), previous medication OR=1.56 (95% CI: 1.12 -2.16, p<0.01) and fever OR=1.43 (95% CI: 1.03-1.199, p=0.03). Disease severity was associated with levels of AST and ALT (p<0.01). Patients taking self-medication OR=1.56 (95% CI: 1.12-2.16; p<0.01) and paracetamol OR= 1.41 (95% CI:1.01-1.98; p=0.04) had higher risk of liver injury. Meanwhile, corticosteroids OR=0.55 (95% CI: 0.38-0.78; p<0.01) and enoxaparin OR=0.53 (95% CI: 0.35- 0.81; p<0.01) were protective factors. Conclusions: Peruvian patients with COVID- teration in liver function tests, high levels of AST and ALT were related to disease severity.

Authors: Cano Diego , Otero William , Gómez Martín , Marulanda Hernando
Published: May 2022

Introducción: El cáncer de colon y recto (CCR) es el tercer cáncer más frecuente y la cuarta causa de muerte por cáncer en el mundo. En Colombia, es la tercera causa de muerte por cáncer. La recomendación más aceptada es hacer tamización con colonoscopia en personas de 50 a 75 años. Sin embargo, recientemente la Asociación Americana de Cáncer (ACS) ha recomendado iniciar la tamización a partir de los 45 años. En nuestro medio no hay estudios sobre prevalencia de pólipos adenomatosos en menores de 50 años. Objetivo: Comparar la prevalencia de pólipos adenomatosos durante colonoscopia de tamización en personas de 45-49 años (casos) y compararla con la de personas de 50 a 75 años (control). Materiales y métodos: Estudios de casos y controles. Los datos se recolectaron de forma prospectiva durante el periodo de enero 2018 hasta noviembre de 2019 en el centro de gastroenterología y endoscopia digestiva de Bogotá Colombia. Resultados: Se incluyeron 490 pacientes, 119 casos y 371 controles, relación casos:control fue 1:3. La prevalencia de pólipos en los casos 36,7% y en los controles (42,5%) p=0,279. Los pólipos adenomatosos se detectaron en 18,5% (IC 95% 12,4-26,6) de los casos y 32,4% (IC 95% 27,7-37,2) de los controles (p=0,004). Conclusión: La prevalencia de pólipos durante la colonoscopia de os es similar a la esperada en colonoscopias de tamización de personas entre los 50-75 os. Este hallazgo favorecería colonoscopia de tamización a partir de los 45 años.

Authors: Bravo-Taxa Mercedes , Chuquillanqui Llimpe Jorge , Taxa-Rojas Luis
Published: May 2022

El cáncer colorectal es el tercer tipo de neoplasia maligna más frecuentemente diagnosticada para ambos sexos. El adenocarcinoma es el tipo histológico que constituye el 86% de todos los casos de carcinoma colónico; sin embargo, existen otros subtipos menos frecuentes, como el carcinoma adenoescamoso, una neoplasia sumamente rara, pero con peor pronóstico y menor sobrevida. Presentamos el caso de una paciente mujer de 68 años con un tiempo de enfermedad de 2 años, caracterizado por anemia, hematoquezia y dolor abdominal. El estudio colonoscópico reveló la presencia de tumoración a nivel de colon ascendente, el cual luego de la resección quirúrgica y estudios anatomopatológicos, resultó corresponder a un carcinoma adenoescamoso primario colónico.
Serrated polyps: innocent or guilty?
Authors: Mansilla-Vivar Rodrigo , Petruzzellis Carlo , Olivari Nicola , Milluzzo Sebastian Manuel , Grassano Alessandra , Cesari Pietro , Zorzi Fausto , Spada Cristiano
Published: May 2022

Serrated lesions represent a group of lesions with different genetic and biological features causing important clinical repercussions. Three types of serrated lesions are identified: hyperplastic, sessile adenomas (with and without dysplasia) and traditional serrated adenomas. Such lesions are now recognized as precancerous lesions.The carcinogenic process of serrated lesions follows a pathway including: alterations concerning activation of mitogen and protein kinase regulating the extracellular signal of other intracellular kinases (MAPK-ERK), inhibition of the apoptosis and hypermethylation of DNA and instability of microsatellites. Like for adenomatous polyps, the risk factors for serrated lesions are environmental factors, related to lifestyle and diet. The cancerogenic risk is increased by excessive alcohol consumption, obesity and poor intake of folate. When a high number of colorectal polyps with architecture serrated is diagnosed, it could be considered as serrated polyposis syndrome (SPS). According the most recent ESGE guidelines, the diagnostic criteria of the SPS, are: at least 5 polyps resected proximal to the sigmoid colon, 2 of which> 10 mm, or >20 serrated lesions of any size distributed in the entire colon. This condition presents a high risk for personal and/or familiar CRC, for this reason a regular screening colonoscopy should be performed in these patients and in their first-degree relatives.

Authors: Mathews Joyce
Published: May 2022

A quasi-experimental study was undertaken to study the effect of Kangaroo Mother Care (KMC) on neonatal temperature and weight among newborns in SCB Medical College and Hospital, Cuttack. A sample of 40 newborns in the post-natal wards was selected among which 20 were put in the control group and 20 in experimental group. The mothers of the experimental group were educated about KMC, and made to practice the KMC method on their babies. Thereafter the temperature and weight of the babies were checked for 4 consecutive days. Mean, standard deviation, standard error and paired ‘t’ test were compared from the row score obtained in pre-test and post-test. It was observed that the babies in the experimental group showed better thermoregulation and weight gain than those in the control group. The study concluded that KMC promotes good temperature control and better growth for pre- and term newborns.

Examining The Effects of Widowhood Rites Practices: A Case Study Among The People of Talensi and Nabdam In The Upper East Region of Ghana
Authors: Ba–an Maxwell Tengolzor , Segbefia Samuel Kwabla , Ofori Maxwell
Published: May 2022

Some practices are barbaric, atrocious, backward, immoral, commoditization and an abusive violation of the sexual and human rights of the powerless. Widowhood rites are performed at the fresh funeral and during the final funeral rites. Widows prefer to be inherited by their grandsons so that they are free to choose a man of their choice and still hold on to their deceased husband assets. The Talensi widow would strangle a goat and part of the skin is used to cover the private of the dead for burial. The Nabdams would slaughter a sheep and an elder will slaughter it. In both cases older women served as the enforcers and custodians of such practices. The purpose of this study was to examine widowhood rites practices among the people of Talensi and Nabdam in the Upper East Region of Ghana. The study employed ethnography research method. Purposive sampling technique was used to sample twenty (20) widows from Talensi and Nabdam. The study recommended that Ghana's widows need to lead in the reporting of violations of their rights to the appropriate state institutions responsible and follow up to ensure justice is delivered. Non-governmental Organizations and Community-based organizations which are advocating for the abolition of widowhood rites should collaborate with traditional authorities to modify the practices.
Factors Influencing the Implementation of Integrated Financial Management Information Systems: Study Focus on Bangladesh
Authors: Noor Md Asad
Published: May 2022

Background of the study: Integrated Financial Management Information Systems (IFMIS) can help improve public sector management by giving managers real-time financial data to make better decisions. The Bangladeshi Public Service is currently busy with the implementation of an IFMIS. However, implementing IFMIS such a project has proved to be a demanding undertaking and has not been met with resounding success.

Objectives of the research: The research is primarily focused to identify the factors influencing the implementation of IFMIS in Bangladesh. Along aside, this paper assesses the influence of technical capacity of staff on implementation of IFMIS in Bangladesh’s public institutions and staff resistance on the deployment of IFMIS.

Methodology of the research: The paper draws from two theories in investigating the issues of IFMIS adoption for public financial management. The theories include System Theory and Rodger’s Theory. A simple Random sampling technique is used to collect the information from targeted respondents with a structured questionnaire. Around 80 respondents were selectively targeted.

Findings of the research: One of the Major findings of the study is that the governments have a strategic plan that recognizes political, administrative, and capacity limits that were found to be supported by respondents. The study indicates that the government has revised the wage structure to compete with the private sector and to prevent skilled employee turnover. Research

shows that employees have the necessary skills and credentials to implement IFMIS. Furthermore, the study looked at how IFMIS deployment is affected by capacity and abilities. Contributions of the research: The results revealed a significant connection between capacity and skills and IFMIS deployment. However, it is found that the infrastructure is central concern for successful IFMIS implementation. Moreover, the government's interaction with the external consultants is seen to be indecisive. Finally, the study recommends that government should uphold the strategic plan that identifies all the constraints and should have detail plan for maintaining its education system's alignment with information technology.

The popular concept of a robot is of a machine that looks and works like a human being. The industry is moving from current state of automation to Robotization, to increase productivity and to deliver uniform quality. The industrial robots of today may not look the least bit like a human being although all the research is directed to provide more and more anthropomorphic and humanlike features and super-human capabilities in these. One type of robot commonly used in industry is a robotic manipulator or simply a robotic arm. It is an open or closed kinematic chain of rigid links interconnected by movable joints. In some configurations, links can be considered to correspond to human anatomy as waist, upper arm and forearm with joint at shoulder and elbow. At end of arm a wrist joint connects an end effect which may be a tool and its fixture or a gripper or any other device to work.

Published: May 2022

Introduction: In recent years, resin-matrix composite materials have revealed a fast technological improvement for dental applications. However, there are still some drawbacks related to the chemical composition, polymerization, and mechanical properties of resin-matrix composites with consequences in long-term clinical success. Objective: This study aimed to perform a narrative review regarding the effects of inorganic fillers on the organic matrix polymerization of resin-matrix composites. Materials and Methods: A search was performed in PubMed using relevant related key terms related to the chemical composition, properties and polymerization of resin matrix composites. Relevant studies published between 2001 and 2021 were selected. Results: The studies included in the present research provided relevant information on the chemical composition and properties of resin composites and polymerization factors, including the time, wavelength mode, and equipment. Studies have reported that silica and silicate nano-scale particles improve light transmission through resin-matrix composites and the degree of conversion of monomers in the organic matrix. Micrometric particles with a high refractive index can decrease the degree of conversion of monomers in the organic matrix. Conclusion: The polymerization of resin matrix composites is affected by light scattering due to the type of inorganic particles and the differences in refractive indexes of inorganic and organic contents.

The effect of core stability on male water polo players’ jump height and throwing velocity
Authors:   , McKenzie Nicole Ashley
Published: May 2022

BACKGROUND Water polo is a highly competitive and physical sport where athletes are continuously looking for ways to improve their performance and reduce injuries. Core stability has been extensively studied in its role to improve athletic performance and to reduce the risk of injuries in overhead throwing athletes. AIM To determine the role of core stability in male water polo players’ by identifying the relationship between core stability, jump height and throwing velocity. OBJECTIVES To measure core stability, jump height (cm) and throwing velocity (km/h) in male water polo players and to identify if any correlations exist between them. METHOD Core stability was assessed in twenty-six asymptomatic male water polo athletes using the PRONE and SUPINE tests. Participants jump height (cm) and throwing velocity (km/h) were measured using a modified yard stick and speed radar gun. IBM SPSS version 24 was used to analyse the data. A probability (p) value less than 0.05 was considered statistically significant. RESULTS The mean values for jump height were calculated at maximum head height (64.22 cm) and head height at ball release (59.50 cm) respectively. Throwing velocities ranged from 50.33 km/h to 77.33 km/h. There was a significant relationship between: core stability and maximum head height (p=0.027), head height at ball release (p=0.025) and throwing velocity (p=0.001). Significant correlations were depicted among the three outcome measures. The strongest relationship was between maximum head height and head height at ball release (r = 0.945). CONCLUSION The results of this study show that core stability significantly affects throwing velocity and jump height in water polo athletes with the largest difference being between moderate and excellent core stability.
The evaluation of miasmatic nosode prescriptions at a Homoeopathic Community Clinic
Authors:   , Wulfsohn Kyle
Published: May 2022

The current study sought to ascertain if any disease patterns or miasmatic trends exist at Ukuba Nesibindi Homeopathic Health Centre (UNHHC) (and the nature thereof). The results of this investigation will enhance our understanding of the trends related to disease, prescriptions and miasms at this community clinic. These findings can be used to inform and improve the current homeopathic management of patients in this particular location. UNHHC is a thriving clinic and further insight into possible miasmatic trends is likely to have a large impact. Aims: The aim of this study was to evaluate miasmatic nosode prescription trends at a homeopathic community clinic. Furthermore, the objectives of the study were to determine the frequency, dosage, and posology trends in prescription of the miasmatic nosodes and to determine trends in patient diagnosis, as well as miasmatic diagnosis. Methodology: The research methodology comprised a quantitative inquiry and analysis, to provide clinical verification of prescriptions. A retrospective chart review was conducted at the UNHHC based on the relevant patient charts. A rubric was used to document the demographics, clinical conditions, homeopathic guiding symptoms, posology and miasmatic diagnosis of each chart, where a miasmatic nosode was prescribed. Further, a comparison of the guiding prescribing symptoms was made against existing materia medica. Results and Conclusions: The results of the study show that the most commonly prescribed miasmatic nosode was Tuberculinum bovinum (Tub bov) followed by, Psorinum, Medorrhinum, Carcinosin, Bacillinum and finally Syphillinum. The most common miasmatic classification was the tuberculinic miasm. The study also showed that the most common form of prescribing miasmatic nosodes was in the 200th potency given as one powder daily. The most common diagnoses for which miasmatic nosodes were prescribed were skin conditions. The conclusion drawn from this study is that the miasmatic trend prevalent at UNHHC is the tubercular miasm, with the majority of manifestations appearing on the skin, requiring the 200th potency given daily.
A gyermek, a család és a pedagógus egysége a Waldorf-óvodában : Gyermek- és családvédelem a jogalkotásban és a pedagógiában (Első rész)
Authors: Márföldi Erika
Published: May 2022

Kutatásom tárgyát annak vizsgálata képezte, hogy a gyermek egészséges fejlődése szempontjából hogyan változik a nevelési környezet, milyen alapminőségekkel kell a gyermekről gondoskodni a pedagógusnak, a családnak és az egész társadalomnak. A gyermekek védelmét, a gyermekek jogait számos hazai és nemzetközi jogi egyezmény deklarálja, éppúgy, mint az óvodai programok. Az elmúlt száz évben a Waldorf-pedagógia elterjedését figyelhetjük meg szerte a világban. Magyarországon napjainkban már több mint 50 Waldorf-óvodában több mint 1700 gyermek nevelése folyik. E pedagógia sajátosságát az adja, hogy a családokkal közösen épül a gyermeket megtartó nevelői közeg. A kutatásban kirajzolódott, hogy a gyermek érdekeit szem előtt tartva a Waldorf-pedagógus folyamatos önképzést végez, a reflektív önértékelési modell a Waldorf-önértékelésnek is részét képezi.

Within 1 (one) year, the increase in cases of tender conspiracy has increased. This shows that many business actors from these actions taken to practice are still in business, which results in unfair competition in doing business. The purpose of this research is to find out how KPPU proves the existence of a tender conspiracy related to Decision No. 14/KPPU-L/2019 and to find out the application of the law according to Law No. 5 of 1999 concerning the Prohibition of Monopolistic Practices and Unfair Business Competition by the judge in decision no. 14/KPPU-L/2019. Conducting this research using library research methods and data analysis used in a qualitative descriptive way is an approach to gain depth, develop theory and social complexity. The writer concludes that in carrying out the proof, KPPU uses the rule of reason and the per se illegal approach. The application of Law No. 5 of 1999 concerning the Prohibition of Monopolistic Practices and Unfair Business Competition by judges related to decision no. 2019 uses an animation stream and a progressive stream which produce an explanation of the relevant laws and regulations, about vertical conspiracy, and about fulfilling the elements of article 22 of Law No. 5 of 1999.

Authors: Chao Yi-Sheng , Vu Thyna , McGill Sarah C. , Gates Michelle
Published: May 2022

Most of the identified published research focused on characteristics or outcomes of having post–COVID-19 condition (e.g., symptoms, quality of life) or predictors for developing post–COVID-19 condition. There were fewer studies related to preventing post–COVID-19 condition or treatments. Ongoing studies, according to published protocols, will investigate interventions to prevent or treat this condition.

Notable evidence gaps included post–COVID-19 condition as it relates to people living in rural or remote areas, children and adolescents, and vaccination status. There were few economic studies, qualitative studies, and studies assessing health systems issues.

Most identified guidelines regarding the diagnosis, treatment, and management of post–COVID-19 condition, including all Canadian guidelines, provided limited guidance specific to patients meeting the WHO definition. These guidelines will need continual updates as new evidence emerges.
Melatonin for the Treatment of Insomnia: A 2022 Update
Authors: Hamel Candyce , Horton Jennifer
Published: May 2022

Two umbrella reviews, 7 systematic reviews, and 2 randomized controlled trials provided mixed results on the clinical effectiveness of melatonin for insomnia, when compared to placebo. Some studies reported improvement in sleep and quality of life outcomes with melatonin, and some studies reported no difference between patients who received melatonin and those who received placebo.

Efficacy of melatonin was measured both objectively (e.g., polysomnography, actigraphy) and subjectively (e.g., validated questionnaires, sleep diaries), and was measured across multiple outcomes.

Two guidelines recommend melatonin for insomnia, but the strength of the recommendations was not reported. One guideline recommends melatonin for insomnia, based on very low evidence (but the evidence was unclear). One guideline recommends against melatonin for chronic insomnia disorder (weak recommendation). The evidence for these recommendations was not well reported across the guidelines.

No studies were found that evaluated the clinical effectiveness of melatonin compared to prescription sedatives in people with insomnia that met the criteria for this review.

No studies were found for the cost-effectiveness of melatonin in people with insomnia that met the criteria for this review.
Science teachers’ experiences on ICT integration: challenges, coping mechanisms, and opportunities
Authors: Alpuerto Reynato Jr.
Published: May 2022

This study was undertaken to investigate the challenges experienced, coping mechanisms employed by, and opportunities for possible intervention schemes to help science teachers in their pedagogical integration of ICT in their classroom instruction. This study was conducted in Magsaysay North District of the Division of Davao del Sur last August through October of 2019. This was participated by 10 science teachers, 4 science coordinators, and 1 district science coordinator. Data collection was done through in-depth interviews and focus group discussions using a semi-structured interview guide questionnaire. Colaizzi's method was used for qualitative data analysis. Responses show that teachers’ challenges in integrating ICT were classified as either self-level or institution-level barriers. Teachers’ coping mechanisms include self-training and support, collaboration with colleagues and knowledgeable others, as well as, time management and self-organization. Opportunities for possible intervention schemes provided by the focus group include inclusive teacher training and professional development, procurement of sufficient ICT infrastructure, installation and updating of relevant educational software. Science teachers undeniably experienced challenges in their utilization of ICT in their instruction but were also able to employ strategies to circumvent such setbacks. With further significant interventions, they can be helped to improve their practice.

Image Muting of Mixed Precipitation to Improve Identification of Regions of Heavy Snow in Radar Data
Authors: Tomkins Laura M. , Yuter Sandra E. , Miller Matthew A. , Allen Luke R.
Published: May 2022

Abstract. In winter storms, enhanced radar reflectivity is often associated with heavy snow; however, some higher reflectivities are the result of melting and mixed precipitation. The correlation coefficient (a dual-polarization radar variable) can identify regions of and mixed precipitation, but this information is usually presented separately from reflectivity. Especially under time pressure, even experienced meteorologists can mistake regions of mixed precipitation for heavy snow because of the high cognitive load associated with comparing data in two fields while simultaneously attempting to discount a portion of the high reflectivity values. We developed an image muting method for regional radar maps that visually deemphasizes the high reflectivity values associated with mixed precipitation. These image muted depictions of winter storm precipitation structures are useful for monitoring real-time weather conditions and for analyzing storms.
