Design and implementation of Threefish cipher algorithm in PNG file
Authors: Nori Ahmed S. , Abdulmajeed Ansam O.
Published: May 2021

This paper is presenting design and implementation of Threefish block cipher on grayscale images. Despite the fact that Threefish block cipher is one of the best secure algorithms, most studies concerning Threefish have focused on hardware implementation and have not commonly been applied on image encryption due to huge amount of data. The main contribution here was to reduce the time and the amount of data to be encrypted while maintaining encryption performance. This objective was achieved by encrypting just the most significant bits of image pixels. A 256-bit plain text blocks of the Threefish was constructed from 2n most significant bits of the pixels, where 0<n<3. Furthermore, Threefish block cipher was applied when n=3 to analyze the impact of uninvolving some bits in encryption process on the encryption performance. The results indicated that the encryption achieved good encryption quality when n=1, but it might cause some loss in decryption. In contrast, the encryption achieved high encryption quality when n=2, almost as good as the encryption of the whole pixel bits. Furthermore, the encryption time and the amount of data to be encrypted were decreased 50% as n decreased by 1. It was concluded that encrypting half of the pixel bits reduces both time and data, as well as significantly preserves the encryption quality. Finally, although the proposed method passed the statistical analysis, further work is needed to find a method resistant to the differential analysis.

Design and fabrication of a 6dB compact directional coupler
Authors: Bučo Muamer , Imeci Sehabeddin Taha
Published: May 2021

In this paper, we will present a planar geometry design for a 6dB compact microwave coupler, and will further explore and discuss the results of an electromagnetic simulation in Sonnet® Suites™ Electromagnetic simulation software. Being a compact coupler, the device features a minute circuit footprint size, while still observing the limitations of the production technologies involved in manufacturing it. The technology utilized in the paper is a 4 port microstrip copper trace on a production-friendly and extremely economical FR4 dielectric substrate. The circuit shows excellent performance in a 1.8GHz bandwidth (3.9GHz – 5.7GHz), with a loss of 6dB on the coupled port. A further advantage of this geometry is a very linear and predictable change in the S-parameter values as a result of small linear changes in the geometry

Authors: Ситченко А.Л.  , Корнієнко І. А.
Published: June 2021

У статті висвітлюються ключові проблеми вивчення літератури в закладах загальної середньої освіти, пов’язані з логічно-понятійним аналізом художнього твору та його емоційно-естетичним сприйняттям учнями. Метою вивчення художнього твору вважається емоційно-розумовий та морально-естетичний розвиток читачів-учнів, що відповідає парадигмі особистісно зорієнтованої освіти, зумовлюється специфікою мистецтва слова й забезпечується характером пізнавальної діяльності читачів-учнів.Пізнання художнього твору відбувається на основі вчення О. Потебні про слово-образ, його суб’єктивне значення у певному контексті, внаслідок чого слово набуває додаткового значення, яке й надає йому образного характеру. Таким чином реалізується не лише зображувальна функція слова. а й виражальна.Авторами проаналізовано наукові праці, що вказують на аналітичний процес естетичного сприймання художнього твору, а також розкривають можливості технологізованого навчання літератури як ефективного чинника розумового розвитку та особистісного становлення школярів. Пропонується поєднувати у навчанні алгоритмізовані схеми діяльності, що характеризуються більш-менш точним відтворенням розумових дій та їх результатів, і пошукові технології, які менш регламентовані й забезпечують творчий характер пізнавальної діяльності.Наводяться приклади, що ілюструють логіку й послідовність розумових дій алгоритмічного типу, а також порядок пошукової роботи, яка стимулює творчі зусилля школярів. На прикладі вивчення роману-хроніки П. Куліша «Чорна рада» продемонстровано висунення учнями гіпотез щодо пояснення національних проблем українського народу та варіантів можливого розвитку художньо-історичних подій, що сприяло активізації пізнавальної діяльності учнів та вихованню їх національної свідомості.

Authors: Muhammad Khan , Mohsin Saima , Pirzada Sarmad , Qasmi Shamsul Arfin , Kanpurwala Muhamamd Adnan
Published: June 2021

Background: Anemia is the most common blood disorder in patients with Type 2 diabetes. The hematological profile of diabetic patients is often missed clinically until to start the manifestation of clinical features of anemia. Anemia increases the hindrances and financial burden on the patient by frequent hospitalization. It increases the risk of microvascular complications, heart diseases, morbidity and death in diabetes mellitus. Therefore, it is imperative to recognize and treat anemia for the sake of patient care.

Objectives: To evaluate the frequency of anemia in Type 2 Diabetic patients attending diabetic outpatients clinics of Mirpurkhas, Sindh.

Methodology: A case-control study has been done to compare the hemoglobin level of Type 2 diabetics and non-diabetics. The data was collected over a period of three months from the patients who were visiting the diabetes clinic for their regular checkup. Data for controls were collected from the patient’s attendants. Diabetics and non-diabetics were under observations throughout the period. There were 206 subjects’ including 106 diabetics (52 females and 54 males) and 100 non-diabetics (50 females and 50 males). Research concerns included the duration of the disease, family history & presence of hypertension. Methods such as cyan methemoglobin were used to estimate hemoglobin & random blood glucose by glucose oxidase as recommended by the World Health Organization (WHO) and then read through Micro-lab 300 chemistry analyzer.

Results: The frequency of occurrence of anemia in diabetics was 33.3% in males and 48.1% in females. Whereas in controls, 16.0% males and 32.0% females were anemic. The family history of diabetes and hypertension was also found higher among diabetic individuals as compare to healthy counterparts.

Conclusion: The study has shown that anemia is twice as common in diabetics as compared with non-diabetics. Early diagnosis of anemia in a diabetic patient, and to treat so, will improve the quality of life and delay the complications to be developed in these patients.

IgG4 aortitis of the ascending thoracic aorta: A case report and literature review
Authors: Shilagani Chaitanya , Lansman Steven , Gilet Anthony , Flusberg Milana
Published: May 2021

IgG4 aortitis is a recently recognized entity that can have clinical and imaging features that mimic acute aortic syndrome. Therefore, it is imperative for radiologists to be aware of how to potentially differentiate the two. Although this entity has been previously described via case reports and meta-analysis in the context of inflammatory abdominal aortic aneurysm, very few cases of ascending aortic involvement have been reported. In this case report, we present a case of a 60-year-old female transferred from another facility for an initial diagnosis of intramural hematoma of the ascending aorta and later found to have IgG4 aortitis post aortic root repair. This is a histologically confirmed case of multi-segmented IgG4 aortitis with rare involvement of both ascending and infra-renal aorta. We will briefly discuss the pathophysiology of IgG4 aortitis, along with review of literature.
Motor Speed Matters! Cognitive Profile of Parkinson's Disease Patients With and Without Deficits in Motor Speed
Authors: Menon Vidya , Hegde Shantala , Pratyusha P V , Kamble Nitish , Yadav Ravi , Bhattacharya Amitabh , Pal Pramod K
Published: May 2021

Background:

Parkinson's disease (PD) is characterized by bradykinesia, tremor, rigidity, postural instability and cognitive deficits in attention, executive functions, learning and memory. Motor speed, measured using Finger Tapping Test (FTT), is an important indicator and predictor of cognitive and motor functions. Deficits in motor speed have significant impact on performance on other neuropsychological tests.

Objective:

This study aimed to understand and compare the cognitive profile of patients with and without deficits in motor speed as evaluated on the FTT.

Method and Material:

A detailed neuropsychological evaluation using the NIMHANS Neuropsychological Battery was carried out on 70 PD patients. The PD patients were divided into patients with (n = 46) and without (n = 24) motor speed deficits. The two groups were comparable with regard to age (P = 0.591), years of formal education (up to 10th – 24.3, above 10th – 75.7) duration of illness (P = 0.703) and age of onset (P = 0.721).

Results:

Across the various cognitive domains such as executive functions, verbal recognition, visuospatial functions, visual learning and memory, the group without deficits in motor speed performed significantly better in comparison to patients with motor symptoms.

Conclusion:

A short and simple test such as FTT may be helpful in predicting the range and severity of cognitive deficits across other cognitive domains in patients with PD. Future studies on larger cohort examining the intricate role and association of FTT and other motor functions such as dexterity may be helpful in understanding the nature and severity of other cognitive functions in this clinical population.

The incidence of cerebral aneurysms is rare in children, and it has to be definitively ruled out in all cases of intracranial bleed even if there is associated history of trauma. We report a case of 11-month-old girl who presented with intracranial bleed after a history of minor trauma whose diagnosis of an intracranial aneurysm was initially missed which later led to a rebleed. It was managed emergently with endovascular coiling and the patient showed incredible recovery in the post-operative period.

Authors: Holla Vikram V. , Chaithra Sudhakar Pushpa , Prasad Shweta , Pal Pramod Kumar
Published: May 2021

Dystonia is the most common delayed movement disorder poststroke with basal ganglia involvement seen in the majority of them. Dystonia usually develops within 1 year of stroke. We report a case of poststroke cervicobrachial segmental dystonia which developed after 9 years of ipsilateral cerebellar stroke. Dystonia can be a sequela of cerebellar stroke, and may occur even after a prolonged latency. This should be considered in a case of segmental dystonia with the past history of cerebellar stroke.
Morphometric mapping of the macrostructural abnormalities of midsagittal corpus callosum in Wilson’s disease
Authors: Stezin Albert , Reddam Venkateswara Reddy , Hegde Shantala , Yadav Ravi , Saini Jitender , Pal Pramod Kumar
Published: May 2021

BACKGROUND AND PURPOSE:

The corpus callosum (CC) consists of topographically arranged white matter (WM) fibers. Previous studies have indicated the CC to be discretely involved in WD. In this study, we strived to characterize the macrostructural properties of the CC using midsagittal cross-sectional area and thickness profile measurements.

MATERIALS AND METHODS:

This study was performed using archived magnetic resonance imaging (MRI) scans of 14 patients with WD and 14 age- and gender-matched healthy controls. Using an automated software pipeline for morphometric profiling, the midsagittal CC was segmented into five sub-regions (CC1–5) according to the Hofer–Frahm scheme. The mean thickness and area of different CC segments and their clinical and cognitive correlates were identified.

RESULTS:

The mean area was significantly different only in CC2 segment (94.2 ± 25.5 vs. 118.6 ± 19.7 mm2, corrected P < 0.05). The mean thickness was significantly different in CC1 (5.06 ± 1.15 vs. 6.93 ± 0.89 mm, corrected P < 0.05), CC2 (3.73 ± 0.96 vs. 4.87 ± 1.01 mm, corrected P < 0.05), and CC3 segments (3.42 ± 0.84 vs. 3.94 ± 0.72 mm, corrected P < 0.05). The age at onset of neurological symptoms and MMSE score was significantly correlated with the morphometric changes of CC1 and CC2 segments.

CONCLUSION:

Morphological changes of the CC are discrete in WD. Morphometric loss of CC was associated with an earlier onset of neurological symptoms and cognitive dysfunction in WD.
Stability conditions for reversible and partially integrable systems
Authors: Buzzi Claudio A. , Roberto Luci Any F. , Teixeira Marco A.
Published: June 2021

The purpose of this paper is to provide results like Peixotos Theorem inside a class

\mathfrak{X}

of 3-dimensional reversible systems. We deal with reversible systems associated to an involution

\varphi_1

such that

\operatorname{Dim}\operatorname{Fix}(\varphi_1)

is equal to one. We further assume the existence of a first integral for any

X\in\mathfrak{X}

that leaves invariant any sphere centered at the origin. The main result establishes generic necessary conditions for the structural stability in

\mathfrak{X}

. Stability conditions on generic one-parameter families of reversible vector fields on the two-dimensional sphere are also stated.

Is postoperative nasal packing after septoplasty safe? A systematic review and meta-analysis of randomized controlled studies
Authors: Titirungruang C.K. , Charakorn N. , Chaitusaney B. , Hirunwiwatkul P.
Published: May 2021

Objectives: To systemically review and compare post-septoplasty complications between total nasal packing and other techniques. Methodology: We searched electronic databases (PubMed, Scopus, and Cochrane Library) and additional sources. The most recent search was on November 30th, 2020. Randomized controlled trials (RCTs) comparing adverse events after post-septoplasty nasal packing versus other techniques were included. The outcomes were adverse events, including respiratory distress, oxygen desaturation, pain severity, bleeding, hematoma, sleep disturbance, infection, crusting, epiphora, dysphagia, perforation, adhesion, and residual septal deviation. Results: There were 47 studies (4,087 participants) in this systematic review. Nasal packing was more likely to cause adverse events than other techniques. There were significant increases in respiratory distress, pain, sleep disturbance, crusting, epiphora, dysphagia, and adhesion. There were no statistically significant differences in oxygen desaturation, bleeding, hematoma, infection, perforation, and residual septal deviation. Subgroup analysis found that trans-septal suture was less likely to cause post-operative complications compared with total nasal packing. Conclusion: Nasal packing after septoplasty was more likely to cause adverse events, including respiratory distress, pain, sleep disturbance, crusting, epiphora, dysphagia, and adhesion. Furthermore, there were no benefits of nasal packing in preventing bleeding, hematoma, and residual septal deviation when compared with other techniques. Routine nasal packing after septoplasty should be avoided. Trans-septal suture should be considered instead.

يمكن حل المسائل الثلاثية للاحتمالات الشرطية المصاغة بالاقتران مع نسخة مطبعة من جدول التوافق مثنى-مثنى باستخدام أساليب حسابية أو جبرية لإنتاج علاقات متبادلة مفيدة بين مختلف الاحتمالات الهامشية والتقاطعية والشرطية المرتبطة بهذا الجدول. وعلى وجه الخصوص، يتسنى استخدام الطرائق الجبرية وحدها لربط أبرز أربعة مؤشرات للاختبارات التشخيصية (الحساسية والتحديدية والقيمة التنبؤية الموجبة (ق ن و) والقيمة التنبؤية السالبة (ق ن س)). وبشكل عام، من الممكن نظريًا التعبير عن أي من هذه المؤشرات الأربعة بدلالة المؤشرات الثلاثة الأخرى مجتمعة. وتتبلور هذه الإمكانية هنا، بطريقة حسابية مباشرة، من خلال استخدام رسم (ماسون) لسريان الإشارات. حيث يستخدم هذا الرسم في العلاقات المكونة له مزيجا من قانون الاحتمال الكلي، وقاعدة باييز وصيغة التكملة. وعلى الرغم من البساطة النسبية للصيغ الأربع التي تعبر عن أي من المؤشرات التشخيصية الأربعة بدلالة المؤشرات الثلاثة الأخرى، فإنه يبدو أنها لم يُسمَع بها في الأدبيات العلمية المفتوحة. نحن نطلق على مجموعة من أربع قيم عددية تحقق هذه الصيغ الأربع (ضمن أخطاء التقريب المسموح بها) مجموعة متسقة. نحدد دالتين للاستيثاق من مثل هذه القيم الأربع نسميهما دالة فرق الاستيثاق التشخيصي (ف وش) ودالة نسبة الاستيثاق التشخيصي (ن وش)، وهاتان الدالتان تأخذان قيمتي الصفر والواحد، على الترتيب، عند التعويض فيهما بأربع قيم متسقة. وبالتالي، فإن انحراف قيمتي هاتين الدالتين عن الصفر والواحد، على الترتيب، يمثل مقياسا لعدم الاتساق لأية مجموعة مزعوم أنها تمثل مؤشرات التشخيص الأربعة. وثمة ملاحظة مثيرة للاهتمام هنا، وهي أن مقياسين غير متحيزين هما مقياسا المُنبئية والموسومية يظهران بشكل طبيعي ضمن تعبيري هاتين الدالتين، مما يشير إلى أن الحدين المتبقيين ضمن دالتي الاستيثاق هاتين قد يكونان أيضًا بمثابة مقياسين غير متحيزين. لقد أجرينا اختبارًا مكثفًا لبعض المجموعات المنشورة من المؤشرات الأساسية الأربعة، للتحقق مما إذا كانت هذه المجموعات متسقة أم لا. في الغالبية العظمى من الحالات، كانت المجموعات المنشورة متسقة، وبالتالي فإنها تشهد بشكل مستقل على صحة الصيغ التي أوجدناها. ومع ذلك، ففي عدد صغير (وإن كان مهمًا) من الحالات، صادفنا مجموعات غير متسقة بشكل كبير. وهذا مثير للفضول بشكل خاص، لأنه لا يوجد مجال كبير للخطأ عند حساب المؤشرات الأربعة من البيانات الأولية للموجبات الصادقة والسالبات الصادقة والموجبات الكاذبة والسالبات الكاذبة. ونظرًا لأن المؤشرات الأربعة تشكل ثلاثة كيانات مستقلة فقط (بدلاً من أربعة) ، فإن الباحث لا يتمتع بحرية تخمين هذه المؤشرات الأربعة كلا على حدة، بل يجب أن تقتصر أية محاولة لتقدير هذه المؤشرات الأربعة من خلال رأي الخبراء أو من خلال أي نوع من النماذج على تخمين ثلاثة منها فقط ، ثم يتم استنتاج المؤشر الرابع عدديًا من هذه الثلاثة.
The COVID-19 Pandemic: How Pastors Communicate Faith and Hope to Virtual Congregations
Authors: Naidoo GM , Israel Connie , Naidoo Magdalene Kevisha
Published: May 2021

This paper examines how pastors engaged an online presence to preach the Word of God and address the needs of their congregations, during the crisis of the Covid-19 pandemic lockdown in South Africa. This is set against the Biblical instruction of Jesus Christ to Peter, to “feed my sheep” in John 21: 17, as it is the very same instruction that holds for pastors in churches today. However, the normal operations of the ministry have changed since the COVID-19 pandemic. The Christian church, a close-knit group of believers to whom social and physical distancing are foreign concepts, has had to adapt. Worship sites have been abandoned, and the absence of worshipers has become the norm. Pastoral ministries have been disrupted and call for pastors to embrace new technology to ensure that they have a digital presence with their congregation through social media. This paper argues that these circumstances give the church of God a unique opportunity to rethink how to continue ministry without physical contact. It adopted a mixed methods (qualitative and quantitative) approach, using an online questionnaire and telephonic surveys to engage pastors. The paper utilises the Two-way Communication Model (TCM) and the Uses and Gratification Theory (UGT). It concluded that pastoral care and spiritual counselling are essential in crises, that pastors have embraced social media in their mission, and that there is support for digital technology. The article recommendations that there should be a balanced communication strategy for Pastor’s ministries, and that government partners with faith-based organisations in different ways in a joint effort to combat the virus, while encouraging and supporting congregants.
Endangering the Endangered: Impact of fake Covid-19 Social Media Communications in Zimbabwe
Authors: Mhute Isaac , Mangeya Hugh , Jakaza Ernest
Published: May 2021

The human species is in great danger of extinction due to the novel coronavirus that was first detected in China around December 2019. By March 2021, the world had witnessed over 116million cases, of which 36,223 are Zimbabwean. The disease that the coronavirus stimulates is quite fatal and has seen 2.57million lives succumbing to it, of which 1483 are Zimbabwean, by the same date. No cure has been discovered for it yet, though scientific researchers have already discovered several vaccines with varying efficacies. Employing a socio-pragmatic approach, the chapter explores the impact of fake covid-19 social media communications on efforts to minimize infections and fatalities in Zimbabwe, an already endangered country. It accomplishes this by qualitatively analyzing purposively sampled fake communications in circulation on social media as well as some of the utterances and behaviors people make in response to them. The chapter demonstrates the negative impact of the communications on international mitigating efforts and emphasizes the need for the government, media practitioners and social workers to always be watchful for such misleading communications and in every case to quickly counter their impact by availing correct information to the people.
An attack on the Cross: Spiritual leaders’ accounts of fear and resilience during COVID-19 pandemic

Published: May 2021

This paper provides accounts on the impact that COVID-19 and the subsequent lockdown(s) had on the Church and its leaders in the South African context. The study explores challenges that the leaders faced and how they dealt with them to remain standing despite their fears. The context is COVID-19 pandemic, which brought mass deaths, fear, confusion and frustration to congregations globally. Church leaders faced a challenge to show resilience amid fear because they too were directly affected. Governments introduced regulations that imposed lockdowns to control the spread of the virus. Limiting contact by restricting distance amongst citizens. The church was one sector that could not operate. Although some sectors were never declared essential services like churches, this left vulnerable communities without support in the face of fear. Spiritual leaders had to demonstrate resilience to support the congregants. The key question the researchers seek to understand is to what extent did the
church remain resilient during COVID-19 pandemic? And how did the church leaders deal with fear despite anointing and expectations from the congregants and communities? A qualitative approach was used in this study. COVID-19 has shown that Church leaders are humans and they are also fearful, however their faith in God has assisted them to show resilience even at this difficult time. The study also asserts that governments should consult different groupings of faith-based organisations, not only those that are under organised bodies before embarking on restrictions for pandemic control. Communities encompass many churches and leaders require support to assist them from church members.
Religious Charlatanisms and the Vulgarity of power: A Postcolonial Reading of Bulawayo’s We Need New Names
Authors: Mavengano Esther
Published: May 2021

The end of British rule in Zimbabwe which happened through a protracted liberation struggle against the white regime was celebrated by many across Africa and beyond. The ascendancy of the late president Robert Gabriel Mugabe to the helm of power brought hope for the economic, religious, linguistic, and socio-political freedoms. The attainment of independence was indeed a moment of celebration after several decades of colonial suppression and brutalities against the indigenous black Zimbabweans. What is most troubling is that the euphoria that was triggered by the attainment of independence in 1980 gradually died as the realities of economic, religious, linguistic and socio-political problems resurfaced. This study seeks to interpret NoViolet Bulawayo’s depiction and thematisation of religion and politics in her debut novel We Need New Names. The study mainly focuses on how Bulawayo fictionalises and captures the sordid realities of the religious and socio-political problems that haunt the postcolonial subjects in Zimbabwe under Mugabe’s leadership. Postcolonial thoughts from Spivak and Achille Mbembe inform the readings of the text. The fictive landscape that is captured in the selected novel shows the hollowness of flag independence attained in Zimbabwe. The postcolonial period during the reign of Mugabe inscribes conditions of subjectivity and subalternity. The studied text also problematises religion and uncovers charlatanisms of the prophets and traditional healers who are portrayed as the biblical wolves in sheep’s cloth exploiting those in distress.
Apocalypse then and now! – Political and religious interpretations of tribulations in apocalyptic mind-sets
Authors: Nyahuma Blessing , Kügler Joachim
Published: May 2021

The article has three parts. Firstly, we give an overview on how the Greek-Hellenistic imperialism provoked apocalypticism as a way of resistance to colonization (e.g. Egypt and Judah). Secondly, we show how the early African apocalypticism is very similar to that of the Ancient Near East. In many African countries, colonization was perceived as an apocalyptic phenomenon. Within this mind-set, apocalypticism became an information system that speculated about the true nature of time, space and being. This information system also gave solutions to how the coming destruction could be ameliorated by human ingenuity and actions. This ideology informed liberation movements like the Chimurenga and others. Thirdly, we analyse how the anti-imperial apocalypticism was calmed by an imperially formatted Christianity. Elements like the belief in heaven created a naïve world-denying attitude: ‘this world is not my home I am just passing through.’ Within the African apocalyptic mind-set, COVID-19 is an ambivalent phenomenon. Initially, it was perceived as God's judgment on the ungodly West, but perceptions quickly changed as it later ravaged Africa. Many government officials voiced that COVID-19 is a well-promoted hoax by fake news of prominent western media houses. Some dismissed the existence of the pandemic while others declared that the vaccine is the dreaded 666 mark of ‘the beast’ or the protective masks were blamed the masks of ‘the beast’. COVID-19 apocalypticism thus can be understood as an anti-modern, xenophobic way of constructing identity.
Pathways to Mitigate Challenges of Learner Academic Performance in a Grade 10 Economics Class in South Africa
Authors: Molise Habasisa Vincent
Published: May 2021

This paper aims to explore the pathways to mitigate challenges of learner academic (LAP) performance in a Grade 10 economics class in South Africa. The challenge of poor LAP has ushered a myriad of predicaments in schools globally. These predicaments include lack of teacher inclusion in decision making, inability to work cooperatively together, and lack of professional development opportunities geared towards LAP. The study was qualitative, with 15 participants chosen through purposeful sampling from one rural school in the Thabo-Mofutsanyane education district. This paper is couched in critical emancipatory research with emphasis on the emancipation of the teachers regarding pathways they can self-develop to mitigate the challenges of LAP. The focus group discussions were used to gather information regarding pathways to mitigate the challenges of LAP in schools. The study revealed that teachers possess a very equivocal and varying experience regarding the pathways to use to mitigate the challenges of LAP. The findings suggest that for successful implementation of pathways to mitigate the challenges of LAP, schools need to invest in training teachers for team-teaching and avail the necessary resources (both human and physical) to ensure effective quality teaching and learning exist in the school. The article recommends that schools should develop policy frameworks, together with relevant stakeholders, to guide novice teachers on the strategies they can use to mitigate the challenges of LAP in their classes.

Published: May 2021

The study aimed to determine the relationship between the job performance of individuals working in the sports industry and their perceived stress. The sample of the study consisted of a total of 474 people including 361 male and 113 female that working in a private company operating in the sports industry in Istanbul, and they were selected by purposeful sampling method. After the data showed normal distribution; Independent t-test, ANOVA and Pearson Correlation analysis were used to analyse the data. According to the result of the analysis, there was no statistically significant difference found between the job performance and perceived stress levels of the participants according to their marital status and educational status. A significant difference was found in the perceived stress levels and job performances of the individuals according to their gender and working period in the workplace. Finally, it was found that there was a negative and low-level relationship between the perceived stress scale and job performance scale. As a result, it was determined that the stress perceived by the individuals and their job performance levels differed according to the socio-demographic characteristics of the individuals, and the higher the stress levels perceived by the individuals, the lower their job performance were.
