Background. Bacterial ﬁlms are a marker of chronic recurrent infections. Bioﬁlms on mucous membranes block the inﬂammatory response of the macroorganism, suppressing the activity of immunocytes, and thereby allow microorganisms to reach high concentrations. Currently, research is being conducted to ﬁnd medications that can act on bioﬁlms. Enzymes, especially their complexes, are substances that can destroy bacterial ﬁlms. Objective. Еo determine in vitro the sensitivity of bacterial bioﬁlms formed by vaginal microorganisms to the complex of enzymes included in Wobenzym. Materials and methods. The study included 72 clinical isolates of pure microorganism cultures isolated from the vaginal biotope: Gardnerella vaginalis (3), Enterococcus faecalis (9), Escherichia coli (18), Klebsiella pneumoniae (15), Klebsiella aerogenes (3), Lactobacillus crispatus (3), Streptococcus pyogenes (3), Acinetobacter baumanii (3), Staphylococcus aureus (3), Candida albicans (3), Enterococcus faecium (3), Streptococcus agalactiae (3), Lactobacillus acidophilus (3). Bacterial bioﬁlm formation was determined in polystyrene ﬂat-bottom plates using a modiﬁed method of Christensen et al. (1985). The tablet form of Wobenzym was used in the study. The tablet shell was washed with saline, the tablet itself was dissolved in 10 ml of 0.9% NaCl and used for in vitro studies. The result was determined using a reader on a spectrophotometer to determine the optical density (OD) of the formed bioﬁlm. It was believed that the drug acted on the bacterial ﬁlm, reducing the OD by more than three times. Results. An in vitro study revealed clinical isolates of bacteria that formed bioﬁlms of varying severity. Of the 72 clinical bacterial isolates, 38 formed bioﬁlms. A pronounced eﬀect of the complex of enzymes included in Wobenzym on bioﬁlms formed by microorganisms such as A. baumanii, S. aureus, G. vaginalis and E. faecalis was noted. Conclusion. Wobenzym has an eﬀective destructive eﬀect on bioﬁlms formed by various microorganisms, including G. vaginalis, common causative agents of bacterial vaginosis, as well as staphylococci and enterococci, causative agents of aerobic (nonspeciﬁc) vaginitis. Conclusion. The drug Wobenzym has an eﬀective destructive eﬀect on bioﬁlms formed by various microorganisms, including Gardnerella vaginalis, common causative agents of bacterial vaginosis, as well as staphylococci and enterococci, causative agents of aerobic (nonspeciﬁc vaginitis).

Background. The cytoskeletal protein β-tubulin class III (Tubb3) is associated with tumor resistance to taxanes and vinca alkaloids, as well as with the metastatic potential of neoplasm, however, data from immunohistochemical analysis of Tubb3 expression in non-small cell lung cancer (NSCLC) tissue are few and contradictory. Purpose. Characterization of the level and intensity of Tubb3 expression in NSCLC tissue and analysis of the identified parameters correlation with clinically significant characteristics of the disease. Methods. Quantitative assessment of the level and intensity of Tubb3 expression in 120 surgical samples of NSCLC was carried out by immunofluorescence method associated with flow cytometry. Primary rabbit monoclonal antibodies specific to Tubb3 and secondary anti-rabbit antibodies conjugated with fluorescent dye DyLight650 (ab98510, UK) were used. The expression of the marker was assessed by two parameters: the level of expression measured as the percentage of the cells expressing Tubb3 and the intensity of expression in conventional units (CU) represented as the ratio of the geometric mean fluorescence intensity in the experimental and control samples (cells incubated with secondary antibodies only). Results. 1. Tubb3 expression was detected in all NSCLC samples studied. The median level and intensity of Tubb3 expression was 30.5% and 2.0 CU with significant differences (up to 10 times) in the quantitative values of both parameters in different patients. 2. The distribution of the studied tumors in terms of the level and intensity of Tubb3 expression differs from normal (P<0.001), the associative relationship between the assessed parameters is very strong (Spearman's rank correlation coefficient was 0.91; P<0.0001). 3. Statistical analysis did not reveal correlations between the level of Tubb3 expression and the gender and smoking status of the patients, with the degree of tumor differentiation, as well as with the stage of NSCLC. 4. In the group of lung adenocarcinomas, the median level of Tubb3 expression is higher compared with squamous cell lung cancer in male and female patients (P=0.01). Conclusion. High heterogeneity of Tubb3 expression level in NSCLC tissue in the patients and differences in the parameters between the tumors of various histotypes indicate the importance of further correlation analysis of Tubb3 expression level with the patients' life span in order to identify the prognostic value of the marker.

Published: October 2024

The COVID-19 pandemic has indeed brought about significant changes in various aspects of human life, including daily activities, the global economy, and the financial sector. Restrictive measures aimed at controlling the spread of the virus have prompted greater reliance on digital solutions, including mobile banking, due to limited physical access to traditional banking services. For this reason, this study aims to investigate the factors that influence individual attitudes towards the use of mobile banking during this period. Therefore, this study uses a survey method through a developed questionnaire to collect responses. The questionnaire comprises several sections on the socio-demographic profile and the Likert-scale questions on the interest factors. A total of 274 respondents is successfully obtained through the online medium. The findings suggest that the Perception of Ease of Use (PEOU) and Enjoyment (PE) have a significant positive effect on attitude. In contrast, the Perception of Usefulness (PU) and Perceived Credibility (PC) are then discovered to have no significant impact on attitude toward the use of mobile banking. In summary, this study contributes valuable insights into the factors influencing individual attitudes toward mobile banking at a time when digital financial solutions are becoming increasingly relevant due to the pandemic. The findings underscore the importance of user experience and security considerations in shaping consumer attitudes and, subsequently, the use of mobile banking services.

A dual band flexible antenna based on a circularly polarized modified meshed patch antenna design. This article focuses on some of the most pressing issues in small satellite applications. The antenna optimization and improvement of antenna performance, such as radiation efficiency. As is well known, circular polarization is immune to the Faraday rotation effect in the ionosphere and can thus prevent a 3-dB loss in geo-satellite communication. With the use of the software program Computer Simulation Technology (CST), the proposed circularly polarized modified meshed patch antenna has been created. Therefore, this article also presents a modified design of a circularly polarized meshed patch antenna to reduce the complexity of the antenna and decrease the size as much as it is capable. However, a meshed patch antenna can support a high communication data rate. The antenna architecture will theoretically be consistent with the installation of solar panels. The antenna utilizes a conductive copper as the core material and the substrate using flexible polyimide. The design antenna is very small, having an overall size of 30 * 30 mm when compared to other conventional non-transparent antenna operating at the same frequencies of 2.6, 3.5 GHz. The antenna that is proposed involves two meshed patch elements of same size but in various shapes. Finally, the proposed antenna is integrated into a solar cell by using the amorphous silicon thin film.

Published: October 2024

To address the shortcomings of the global positioning system (GPS) operating within indoor scenarios, a range of indoor positioning systems (IPS) have been proposed. Among these, visible light IPS garners substantial research interest for its potential as a cost-effective IPS solution. However, susceptibility to environmental influences like external light and non-line-of-sight that can significantly affect its performance hindered its adoption. Hence, a simulation framework capable of simulating these influences becomes crucial in supporting the effective deployment and promoting the adoption of visible light IPS. This paper investigates the feasibility of using a simulation framework to replicate environmental factors affecting the system, including external optical sources and blocked transmitters. The research involved the development of a received signal strength (RSS) based visible light IPS prototype and an associated simulation framework. Subsequently, the prototype was tested in three distinct environments: no influences, with an external optical source, and non-line-of-sight. The prototype achieved an accuracy of 0.0836 m, 0.3541 m, and 1.1519 m for 50% of the time respectively in these three environments. Ultimately, the simulation framework developed is capable of reproducing similar effects for all three environments with a difference in the accuracy of 76.08%, 74.86% and 867%, respectively. Thus, the findings support the use of the developed simulation framework for the effective development of visible light IPS in environments with no influences and with external optical sources.

Potholes are defects on the surface of roads, streets, or pavements brought on by depressions or holes, which are hazardous for vehicles and pedestrians, whether small divots or huge craters. Various methods have been explored to improve the accuracy of potholes detection. Existing approaches have advantages and disadvantages. This paper presents the proposed method of pothole detection utilising Doppler Radar signal's Power Spectrum Density (PSD) together with the Decision Tree classification algorithm. While continuous waveform (CW) radar is able to identify moving targets, it cannot localise the exact depth of the reflector, which is the prominent characteristic of potholes. In addition, the target's reflected signal is likely to be masked by nearby harmonics. Since the radar is moving despite the target of interest, mounting it on a moving vehicle offers a different perspective. This paper explores the potential of Doppler radar's signal for pothole detection while comparing two Machine Learning (ML) techniques. A commercially over-the-shelf (COTS) K-LC2 Doppler radar was employed to acquire pothole and non-pothole raw datasets. Doppler signal was hardly distinguished between pothole and non-pothole, either in the time or frequency domain. Hence, Doppler signals were converted to power spectral density (PSD), and PSD's features were extracted. Extracted features were applied with the coarse Decision Tree (DT) and K-Nearest Neighbours (KNN) classification algorithms. The result exhibits a better accuracy of 91.2% for 80:20 distribution by using the Decision Tree.

INTRODUCTION. In clinical practice, stress tests are carried out to draw up an individual patient rehabilitation plan, assess tolerance and optimize the load, and evaluate its clinical effectiveness. The Six-minute walk test (6MWT), in the presence of contraindications to the bicycle ergometer test or the impossibility of performing it, is a tool for assessing the response of the cardiovascular and respiratory systems to the load being performed. There is no description in the literature of the relationship between the distance traveled during 6MWT and the peak metabolic equivalent (MET) assessed during the bicycle ergometer test.
AIM. Study the relationship between 6MWT indicators and the results of bicycle ergometer test in patients who have suffered a myocardial infarction.
MATERIALS AND METHODS. During the examination, 56 patients underwent a symptom limited bicycle ergometer test and 6MWT, the peak MET and the distance traveled during 6MWT, as well as changes in the ECG during both tests were assessed.
RESULTS AND DISCUSSION. The average values of maximum heart rate during the bicycle ergometer test and ECG-controlled 6MWT did not differ significantly. The distance in meters during 6MWT and the power of the exercise performed during bicycle ergometer test in MET have a significant relationship, which indicates the comparability of the data from these tests as a criterion of exercise tolerance.
CONCLUSION. The use of 6MWT and bicycle ergometer test allows us to assess various aspects of cardiorespiratory function and physical fitness in patients undergoing a cardiac rehabilitation program. Further study of the possibility of using ECG-controlled 6MWT in the early stages of rehabilitation is necessary to create the most effective and safe physical training for patients who have suffered a myocardial infarction.

Published: October 2024

INTRODUCTION. The widespread use of total hip arthroplasty (THA) places high demands on the restoration of a normal gait pattern and is one of the key goals of rehabilitation.
AIM. Determination of key parameters of walking in patients after THA to assess the effectiveness of restoration of the physiological gait pattern.
MATERIALS AND METHODS. In a control prospective study, the main group consisted of 23 patients (11 men, 12 women, aged from 41 to 75 years, mean age 63.9 ± 9.4 years), who in the first 8 weeks after planned THA, moved with the help of assistive devices. supports (two crutches or walkers) who underwent stage II of medical rehabilitation; control group — 27 healthy people (12 men and 15 women, aged from 42 to 73 years, average age 60.9 ± 9.9 years). Spatiotemporal and kinematic gait parameters were recorded before and after the rehabilitation course using a gait simulator with biofeedback equipped with three sensors. For each leg, spatiotemporal and kinematic biomechanical parameters were separately recorded.
RESULTS. All spatiotemporal gait parameters on both limbs and pelvic mobility in the sagittal plane in patients in the early recovery period after THA before the start of the rehabilitation course are significantly different from healthy people. After a course of rehabilitation, the studied gait parameters approach physiological values. The main asymmetry is observed in the single support phase from 16 % at the beginning of the course, to 10 % at the end; sagittal pelvic mobility are 2 times higher than the physiological normal meaning at the beginning of the course, without significant changes in dynamics.
DISCUSSION. Disturbances in the gait pattern are observed in the majority of patients undergoing THA. Step symmetry is one of the significant parameters of walking, according to which the primary global assessment of its quality is carried out. Asymmetry of the single support phase of the limbs is a natural development of compensatory motor reactions after endoprosthetics.
CONCLUSION. The gait parameters “step frequency” and “step cycle” quickly change after a course of rehabilitation and can be used to assess the locomotor activity of patients during short courses of medical rehabilitation in the early recovery period. Indicators of stance and swing phases, their symmetry changes much more slowly, can serve as criteria for assessing the effectiveness of measures taken at the stages of rehabilitation in the dynamics of gait restoration.

INTRODUCTION. Overactive bladder syndrome is caused by many factors including obesity, insulin resistance and poor dietary habits. Since it is a chronic disease and needs time to be treated, introducing telepilates in addition to Mediterranean diet would encourage better adherence and results to the treatment program.
AIM. To assess the impact of a virtual group-based telerehabilitation program on overactive bladder symptoms and metabolic health in women with obesity.
MATERIAL AND METHODS. Eighty obese women (BMI 30.0–34.9 kg/m2) between the ages of 35 and 45 were allocated into two equal groups, 40 for each: (A) supervised telepilates and (B) unsupervised telepilates. The supervised group participated in a 12-week Pilates workout program over videoconference platforms three times a week. Meanwhile, the unsupervised group only received four online meetings. The groups’ diet was the Mediterranean style. The Hemostatic Model of Insulin Resistance (HOMA-IR), body mass index (BMI), waist circumference (WC), Patient Perception of Urgency Scale (PPIUS), Overactive Bladder Questionnaire Short Form (OAB-q SF), and Telehealth Usability Scale (TUS) were measured.
RESULTS AND DISCUSSION. The supervised telepilates group exhibited statistically significant amelioration of overactive bladder symptoms and a reduction in HOMA-IR (p 0.001), while the unsupervised telepilates group showed insignificant changes in these measures (p 0.05). Furthermore, the supervised telepilates group showed significantly greater reductions in BMI and WC (p 0.001) than the unsupervised telepilates group (p 0.05). Additionally, the supervised telegroup outperformed the unsupervised telegroup on all parameters of TUS (p 0.001)
CONCLUSION. Women with obesity experienced decrease in overactive bladder symptoms and improved metabolic health after completing a 12-week telepilates training program.

Published: October 2024

INTRODUCTION. Climacteric syndrome is characterized by significant disorders in the nervous, musculoskeletal, urinary and cardiovascular systems in women of the perimenopausal and postmenopausal periods. The main reason is a sharp decrease in estrogen levels. Menopausal hormone therapy is often used for treatment, but due to contraindications and complications, it does not always completely solve the problem. This has sparked interest in alternative treatments such as dry carbon dioxide baths.
AIM. To study the effectiveness of using dry carbon dioxide baths in women with menopausal syndrome and evaluate their impact on the neurovegetative, metabolic and psycho-emotional state of these patients.
MATERIALS AND METHODS. A prospective randomized study was conducted involving 70 patients with moderate climacteric syndrome aged from 48 to 60 years. Using a simple randomization method, the women were divided into 2 groups: 35 patients of the main group received 10 procedures of dry carbon dioxide baths with a CO2 concentration of 15–20 %, temperature 28–32 °C, lasting 15–20 minutes, 35 patients of the control group did not receive any treatment. To assess the effectiveness of treatment, a modified Kupperman-Uvarova menopausal index, an assessment of the effect of “hot flashes” on daily life on the HFRDIS scale, as well as daily blood pressure monitoring (SMAD) were used.
RESULTS AND DISCUSSION. After treatment, patients in the main group observed a significantly significant (p 0.05) improvement in the patients’ condition in the form of a decrease in integral indicators of the modified menopausal index and an assessment of the impact of hot flashes on daily activity on the HFRDIS scale by 28.2 and 43.1 %, respectively, as well as in the form of a decrease in average daily systolic blood pressure by 13.7 %.
CONCLUSION. The use of dry carbon dioxide baths is recommended for use in women with moderate climacteric syndrome, since this method significantly improves the quality of life of patients and is an effective non-drug that can reduce the drug load on the body of a woman suffering from neurovegetative disorders.

Published: October 2024

INTRODUCTION. The healing of burn wounds often leads to pathological scars and scar contractures, significantly deteriorating the quality of life for patients who have experienced burn trauma. In comprehensive anti-scar therapy, balneotherapy with sulfide (hydrogen sulfide) waters can be applied alongside primary methods. However, due to a lack of modern information on its effectiveness, this method is not frequently included in rehabilitation programs.
AIM. To determine the significance of hydrogen sulfide baths in comprehensive rehabilitation and improve treatment outcomes for patients with hypertrophic post-burn scars.
MATERIALS AND METHODS. In the years 2021–2022, 110 patients, including adults and children, participated in an observational study at the Matsesta Balneological Resort (Sochi, Russia) titled “Evaluation of the Effectiveness of Balneotherapy for Post-Burn Scars in Adults and Children”. All patients received a course of 10 hydrogen sulfide irrigations or baths at the Matsesta Balneological Resort. Before the start of the procedure and after completion, scar tissue assessment using the Vancouver Scar Scale and patient surveys were conducted by a physiotherapist.
RESULTS AND DISCUSSION. Among the patients, there were 40 adults and 60 children. The age of patients ranged from 2 to 61 years, with an average of 19.8 years; 49 were male, and 51 were female. The burn area in patients ranged from 5 to 90 % (average 33.1 %) of the body surface. After the first course of sulfide irrigations, the scar tissue assessment on the Vancouver Scar Scale decreased by 2.1 points in children and 2.2 points in adults. After a repeat course of sulfide irrigations, scar tissue assessment decreased by 1.3 points in children and 1.8 points in adults. According to surveys based on the Dermatology Life Quality Index, before treatment, patients subjectively rated their condition on average at 3.45 points, and after treatment, at an average of 2.76 points. The decrease in scores was mainly due to the reduction or disappearance of symptoms such as dryness, burning, pain, and paresthesia in the scar.
CONCLUSION. Balneotherapy with sulfide waters for patients with hypertrophic post-burn scars within the first 24 months after burn trauma is effective for both children and adults.

Behavioral flexibility in self-assurance, organization, and interpersonal competency strongly influenced teacher commitment, according to regression analysis. Thematic analysis of qualitative data showed that teachers had broad behavioral flexibility, moderate commitment, and that behavioral flexibility strongly influences commitment. The regression model shows that behavioral flexibility is one reason instructors' commitment is somewhat high. The data integration method connecting- merging-confirmation explained the study's quantitative outcomes using qualitative results. Thus, the study was done to publish findings in respectable research journals.

Side Channel Attacks (SCAs) and Fault Injection Attacks have emerged as significant threats to the security of electronic devices. This paper explores these hardware attack vectors in the context of recent incidents [11] involving pagers and walkie-talkies. We shall deep dive into the possible mechanisms of these attacks, how they can be combined for increased efficacy, and their implications for device security. This paper discusses only the possible ways [1] the adversaries could have exploited and may include other attack vectors such as supply chain attack and few others. The aim of this paper as we discuss the potential attack mechanisms is only to focus on mitigations and awareness of the reader to perform advanced security testing.

Authors: Fuime Clementine , Wachara Omer Solomon
Published: October 2024

This study was set to find out the training needs of Ward Education Officers` in ensuring Quality Education in Tanzania. It mainly focuses on determining WEO`s supervisory training needs that will enable them to ensure quality education provisions in schools in Mkuranga District, highlighting the challenges that WEO's face while carrying out supervision of schools and establish the remedial measures to the identified challenges WEO's face in Mkuranga District. The study sample comprised of 26 informants made up of 25 WEO`s and 1 District Education Officer (DEO). A concurrent transformative mixed method approach was applied because each method of data collection complements each other. Questionnaires and interview guide questions were used to collect data from the respondents. The reliability of quantitative data was established through Cronbach- Alpha where by (r=0.828 for WEO`s questionnaire) while reliability for qualitative data was established through trustworthiness. Quantitative data was analyzed by using descriptive analysis to generate frequency, means and percentages by using the Statistical Package for Social Science (SPSS) version 25 Computer while Qualitative data was analyzed thematically and presented in words by verbatim quotations. The study concluded that, WEOs are facing the challenges that hinder their ability to provide effective supervision for ensuring quality education in schools. Such major challenges include lack of training, inadequate resources and lack of cooperation from the community in which they work. WEOs are in dire need for training in order to enable them supervises school for ensuring quality education. The study therefore recommends that, the program designers plan for supervising training to the WEOs either before being appointed or the inset training if they want WEOs to fit into there jobs. Also WEOs should only be selected among teachers who have the knowledge of education management and supervision.
The use of French in Revival Churches in a West-Northern Congolese Setting: Case of Gbadolite Town
Authors: BAMOSE NDUNGI Marius
Published: October 2024

Having noticed that pastors in revival churches have established French as language of preaching in Gbadolite, a small town with Lingala as vernacular language, the researcher has attempted to discover the reasons hidden behind this practice. After analysis he seems not satisfied with the five main reasons given by the latters and tries to give alternatives. In reality, this practice helps only to distinguish those revival churches from the traditional ones.
Acute Toxicity and IN VIVO Antischistosomal Effects of Entada africana Guill & Perott (Fabaceae) Methanol Stem Bark Extract in Albino Mice
Authors: M. R. Daben, , E. A. Adeleke, , S. B. Beshel,
Published: October 2024

The study was aimed at determining the acute toxicity and schistosomicidal effects of methanol extract (ME) of Entada africana (E. africana), in albino mice. Fresh stem bark of E. africana was shade-dried and extracted by Soxhlet extraction. Acute toxicity was carried out on 6 groups of mice (n=3) of 6-week-old, sizes 27-30g; to determine the therapeutic index, piloerection signs and possible mortality (LD50) in 24h exposure period. Cercaria from B. globosus snails were shed under a 100W bulb for 2 hours. In vivo antischistosomal assays was by used of 6-weeks old (27-30g) mice. Set I (n=10) involved investigation on schistosomules infection in the mice, 3-7 days post infection (PI). Set II (n=10) was infected and treated with E. africana ME extract, at concentrations 10-100mg/l, 35th day, PI for 5 consecutive days. Set III (n=10), were infected and treated with praziquantel– PZQ (positive control). While set IV (n=10) were infected and untreated (negative control). All were sacrificed, 75th day of PI. Data were analyzed by GraphPad® prism 8.4, version 2020. Findings revealed that E. africana ME did not generate any harmful or clinical effect within 24h, post administration; and there were no obvious reactions such as paw licking, stooling, piloerection or immediate death, except at phase II, 5000mg/kg bwt, (1⁄3) being the highest dosage. Worm burden decreased with increase in concentrations, especially at 70-100mg/l. Lower concentrations (10mg/l), had high worm population (76.00±21.28). Infected and untreated group had highest worm population (189.67±32.52). E. africana ME stem bark extract, showed antischistosomal effect and worm reduction in a dose- dependent pattern.
Teachers’ challenges encountered in the marketisation of education systems at primary schools in the Mbare-Hatfield district
Authors: Mutonhodza Lucky
Published: October 2024

Different forms of markertisation and privatisation have encircled the teaching profession. Internet sites that offer to produce academic work for a fee make academic work into a commodity that can be bought and sold. Most schools in Zimbabwe, the Southern African Development Community region, Africa, and beyond cannot easily afford internet services. This study explored the teachers’ challenges in understanding the educational systems due to the marketisation of education. This study utilized the mixed methods approach and the case study design because of its strength in discovering more about unexplored problems. Two school head participants and forty teachers were selected from schools in the district. Semi-structured interviews and questionnaires were used to get data from the research participants. The results unearthed that the education system is one such tool for perpetuating class divisions and social inequality. Contemporary literature has provided evidence in the exploration of teachers’ challenges encountered in the marketisation of education. To the extent that I have reviewed the literature, I found a substantial gap in knowledge about the impact of the challenges encountered in the marketisation of education. The study's objective was to determine the challenges teachers face in giving equal opportunities to poor and minority students due to the marketisation of education. There are some gaps caused by digital divides and government withdrawal from funding for public schools since the early 1990s when ESAP was embraced as an economic blueprint. The marketisation of education has negatively affected teacher integrity, sometimes leading to teacher misconduct. In recent years, the professional status of teachers seems to have been compromised. This is probably due to the changing nature of teacher professional work. Modern-day teaching practices are embroiled in an increasing struggle for private gain. Teachers must learn to cross social boundaries to make learning meaningful and relevant for all students.
Dropping out of learners with hearing impairment from inclusive classes in urban schools in Bulawayo
Authors: Dube Loveness
Published: October 2024

This study explored factors contributing to the dropping out of learners with a hearing impairment from inclusive classes. It used the interpretivism theory to extract rich data and the qualitative research approach to conduct the study. A case study was used as a research design. In this study, participants were purposively selected. Semi-structured interviews, observations, and document analysis were used to collect data. The findings from the study revealed the challenges encountered in the teaching and learning of learners with hearing impairment. These include curriculum adaptation, social interaction with peers, negative attitudes of teachers and hearing learners, parental involvement, communication barriers, lack of interpreters, high learner ratio, and lack of resources. The findings further revealed that some opportunities are being gained by learners with hearing impairment in inclusive classes, such as access to a wider curriculum, social interaction, enhanced communication, and learning in local schools. However, challenges seemed to outweigh the opportunities gained by learners with hearing impairment, compelling them to drop out of inclusive classes. Therefore, the study gave some recommendations to help curb the dropping out of learners with hearing impairment from inclusive classes. These include allocating more resources in inclusive classes to address the problem of inadequate materials and the fact that government policies on inclusion should be made available to all educators and fully implemented. In addition, supervision, monitoring, support from parents, and evaluation of the system should be done to facilitate the learning of learners with hearing impairment in inclusive classes.
Exploring teachers' experiences in teaching learners with Dissociative identity disorder at rural schools in the Amajuba district KwaZulu-Natal
Authors: Mokoena Nelly
Published: October 2024

This study aims to investigate how Dissociative Identity Disorder (DID) affects learners’ academic achievements, engagements, and overall school experience. The objectives were to identify the prevalence of DID among learners in rural KwaZulu-Natal schools, examine the impact of DID on their academic performance, and explore interventions that could support affected learners. The study gained qualitative insight from interviews and focus groups involving learners, teachers, and psychologists. This comprehensive method facilitated a nuanced understanding of DID's effects on learning and academic outcomes. Results indicated a significant correlation between learners with DID and lower academic performance when compared to their peers without DID. Qualitative findings revealed that dissociative episodes, memory lapse, and the psychological stress associated with Dissociative Identity DID adversely affected learners’ participation in class, homework completion, and exam performance. The study further found a general lack of awareness and resources in rural schools to effectively support learners with DID, compounding the challenges they face. The study concludes with several key findings: the need for targeted training for educators in identifying and supporting learners with DID, the importance of integrating psychological support within the school system, and the potential benefits of personalized learning plans for affected learners. The focus should not merely be on academic performance but on creating a holistic experience where every learner, regardless of their challenges, feels included and valued. The study calls for further research and strategies to identify and address dissociative symptoms in learners.
