Authors: Sudiantika Pande Komang , Raya Nyoman Agus Jagat
Published: September 2024

Patients with Systemic Lupus Erythematosus (SLE) experience various physical and psychological symptoms that disrupt their daily activities. If these symptoms are not addressed, they can be decreased quality of life (QoL). This literature review aims to describe the impact of mindfulness therapy and educational-counseling interventions on the QoL of SLE patients. This study encompasses 1.625 articles obtained from the Google Scholar, PubMed, and Science Direct databases, published within the past five years (2018-2023). A total of eight literature sources were analyzed based on predetermined inclusion and exclusion criteria, as well as the PRISMA flowchart. The results of this literature review identified three themes discussed: mindfulness therapy, educational-counseling, and the QoL of SLE patients. Mindfulness therapy and educational-counseling interventions can reduce stress, anxiety, and depression, decrease fatigue, promote self-acceptance, alleviate pain, and enhance physical activity. These interventions have an impact on improving the QoL of SLE patients. Family members and healthcare professionals, including nurses, play a crucial role in supporting and implementing these interventions.

Authors: Theophilus Kwesi Mensah  , Isaac Djan
Published: September 2024

This research paper explored the cultural dimensions and significance of some selected murals in Accra, Ghana, with the aim of shedding light on the intricate interplay between art, culture, and identity in the urban landscape. Accra, the capital of Ghana, boasts a vibrant street art scenery characterized by a diverse range of murals that reflect the city's rich cultural tapestry and historical narratives. The study was based on murals at three (3) public spaces in Accra. Eleven (11) people, consisting of five (5) muralists and six (6) members of the public, formed the sample for this research. The study employed the qualitative approach, with a multiple case study as the design, combining visual and thematic methods of data analysis to investigate a curated selection of murals across the three selected neighborhoods in Accra. The primary objectives of this paper were to identify the cultural symbols, themes, and stories embedded within the murals and to examine how they contribute to the cultural identity of Accra's residents. Through interviews with artists, community members, and cultural experts, we gained insights into the motivations behind the creation of these murals and their intended impact on the community. The findings revealed that Accra's murals serve as a dynamic means of cultural expression, preservation, and communication. They depicted a wide array of themes, including historical events, social issues, traditional folklore, and contemporary urban life, all of which were deeply intertwined with the city's cultural fabric. Additionally, these murals foster a sense of place, community pride, and cultural continuity, creating a visual dialogue between the past, present, and future. In conclusion, this paper contributes to a deeper understanding of how murals in Accra play a pivotal role in shaping and reflecting the cultural identity of the city. It underscores the importance of public art as a catalyst for cultural preservation, education, and community engagement, ultimately enriching the urban experience for residents and visitors alike.

Authors: David Wambua Makau  , Dr. Susan Nzioki  , Dr. Ann Kalei
Published: September 2024

The performance of teachers in Kenya, measured from their learners’ performance in KCSE, has remained wanting for a long time.  In order to address this challenge, the teachers’ employer, the Teachers Service Commission (TSC), adopted initiatives to manage the performance of duties of her employees. However, these measures seem to have no positive impact. This study sought to establish the influence of performance management initiatives on the performance of public secondary school teachers in Kenya. It sought to establish the influence of internal quality assurance on the performance of public secondary school teachers in Kenya.
The study utilized a mixed-method research design. The study population comprised 122310 public secondary school teachers employed by the Teachers Service Commission and 295 Sub County TSC Directors who are the immediate supervisors of the teachers. Multistage sampling was used to cluster the Country into eight geographical regions administered by TSC regional directors as Primary Sampling Units (PSUs). Each region was again clustered into counties as Secondary Sampling Units (SSUs), and then each county was clustered into sub-counties as Ultimate Sampling Units (USUs), where schools were stratified into National, Extra County, County and Sub County schools where teachers were purposefully selected according to how long they had taught students up to form four per subject and a sub-county director from each sub-county selected.  Slovin’s formula was used to select 399 respondents from teachers and TSC sub-county directors. Self-administered questionnaires were used to collect primary data from teachers, and interview schedules were done for principals and sub-county directors. Collected data was analyzed using SPSS, and descriptive, inferential, and regression statistical techniques were used. Frequencies, Means and Standard Deviations presented the descriptive data, while inferential statistical tests were presented using Pearson Product Moment Correlational Coefficient and regression analyses.
Null hypotheses were tested using the Pearson Product Moment Correlational Coefficient.  The hypotheses’ results indicated that there was a weak significant relationship between internal quality assurance and the performance of public secondary school teachers in Kenya. It was recommended that the TSC should sponsor field officers to monitor and strengthen quality assurance in schools.

The Impact of Armed Attacks on Voter Turnout: A Comprehensive Review
Authors: Dr. John Walah Mua  , Mbamome Divine Nkendong
Published: September 2024

This article examines the relationship between armed attacks and voter turnout. Elections are fundamental to democratic societies, serving as a political participation and decision-making mechanism. However, armed attacks can disrupt the normal functioning of a society and have the potential to influence voter behavior. Utilizing the American Psychological Association (APA) referencing method, this study reviews existing literature, analyzes empirical evidence, and presents a comprehensive overview of the impact of armed attacks on election turnout. The findings suggest that armed attacks can exert both short-term and long-term effects on voter turnout, which vary depending on contextual factors such as the severity of the attack, level of political polarization, and government response. Understanding these dynamics is paramount for policymakers and researchers in developing strategies to mitigate the potential negative consequences of armed attacks on the democratic process.

The US congressional hearing were held between Professor Theodore Postol and Mr. Robert Stein, manager at Raytheon, Patriot’s manufacturer, where its effectiveness was openly debated in April, 1992. The key topic was what is considered to be the success of Patriot. However, Raytheon’s criteria on the success of Patriot was not easy to establish and even raised further questions on Patriot’s effectiveness. At the end, Raytheon even emphasized its political success; regardless of Patriot’s defense effectiveness in air, Patriot ended up keeping the US policy among the allied nations in a region.
The Emergence of a Civil Counter-Terrorism Judge in Cameroon: Simple Mimicry or the Need to Comply with International Law
Authors: Dr. Assira Marthe
Published: September 2024

Cameroon has been plagued by terrorism for several years. The Boko Haram sect is active in the far north, and separatists are perpetuating terrorist attacks in the north-west and south-west of the country. To suppress terrorism, Cameroon adopted the law of 14 December 2014. This law assigns exclusive jurisdiction over terrorism-related litigation to the military courts. Strongly criticized because it undermines the right to a fair trial recognized by international law for the benefit of those prosecuted for terrorism, this law has limitations in terms of its effectiveness. In fact, there has been an upsurge in acts of terrorism in the far north and the NOSO. It is, therefore, legitimate to ask if Cameroon should not, as some countries have done, entrust terrorism litigation to a specialized civil court, which is the best guarantor of a fair trial. This solution could enable Cameroon not only to comply with international law but also to combat terrorism more effectively.
Leveraging Data Analytics for Environmental Sustainability
Authors: Divyeshkumar Vaghani
Published: September 2024

This research work is an assessment of how data analytics contributes to environmental sustainability. The objectives of the study were:

To determine how data analytics affects environmental sustainability,
To find out barriers to data analytics and environmental sustainability, To discover opportunities for data analytics and environmental sustainability, and
To ascertain how data analytics aligns with environmental conservation goals and values.

This research adopts a quantitative questionnaire approach as the method of data collection. Questionnaires were administered to 50 persons; the study used descriptive and inferential statistics to analyse the data gathered, and regression analysis was used to generate inferences from the data, using Statistical Packages for Social Sciences (SPSS). The regression model shows that there is an overall statistical significance between the independent variables (effect of data analytics, barriers of data analytics, and opportunities of data analytics) and the dependent variable (environmental sustainability with a corresponding p-value of 0.038). Therefore, the study recommends that organisations and governments invest in robust data analytics infrastructure to effectively collect, process and analyse environmental data. Efforts should be made to address the barriers identified in the analysis, such as implementation challenges, data quality issues, and scalability concerns, and enhancing data literacy and building analytical skills among environmental professionals is crucial for maximising the potential of data analytics.
DEPOIS DA TEMPESTADE: DESENCONTROS NARRATIVOS ENTRE A COBERTURA JORNALÍSTICA DA TELEVISÃO DE MOÇAMBIQUE E DA EURONEWS SOBRE A PASSAGEM DO CICLONE IDAI POR MOÇAMBIQUE
Authors: Machonisse Tânia , Ribeiro Fábio , Moreira Fernando
Published: September 2024

A partir da teoria das representações sociais (TRS), bem como das teorias do agendamento social (agenda-setting) e do enquadramento noticioso (framing), foi desenvolvido um estudo sobre como a construção mediática se desenvolve a partir de uma agenda local e outra global. Recorrendo a metodologia da Análise Crítica do Discurso (ACD), foram analisadas um total de quatro peças jornalísticas produzidas, durante os primeiros dias após a passagem do ciclone Idai por Moçambique, em 2019, pela Televisão de Moçambique e pela Euronews (duas para cada meio de comunicação social). Desta análise resultam duas linhas de reflexão: 1) as fontes de informação foram selecionadas como mecanismo de visibilidade local, perante a omissão global da presença do Estado Moçambicano nas zonas afetadas; 2) O apelo à solidariedade como uma narrativa nacionalista local e “moralista” global. Este estudo apresenta ainda um breve debate sobre a (im)possibilidade de considerar o jornalismo como alternativa discursiva para a construção de abordagens mais equilibradas sobre a diversidade sociocultural entre países considerados como os centros do mundo e os da periferia. Por fim, este artigo sugere um maior investimento científico na teorização da possibilidade de um jornalismo colaborativo entre o centro e a periferia, entre o global e o local, entre os mútuos “outros”, capaz de assegurar a construção e a representação da realidade sobre desastres naturais e crises humanitárias que enalteçam, de forma holística, os esforços locais e globais para prestar apoio humanitário e na reconstrução pós-desastre.

Published: September 2024

This study aimed to determine the relationship between food delivery app usage, fat intake, physical activity, and the overweight status of students at public high school in Jakarta. The cross-sectional study involved 77 students from grades X and XI. The frequency of food delivery was grouped into ≥3 times/week or less. Types of food were grouped into light or heavy meals. Physical activity was measured using IPAQ-SF (International Physical Activity Questionnaire - Short Form) and fat intake using SQ FFQ (Semi-Quantitative - Food Frequency Questionnaire). Fat intake was grouped into sufficient and excess category. Physical activity was grouped into low and sufficient category. Chi-square analysis found that there is a significant correlation between overweight status and frequency of food delivery application usage (p<0.001). However, there is no significant correlation between overweight status with the type of food ordered (p=0.467) as well as the amount of food ordered (p=0.655). On the other hand, fat intake showed a significant association with overweight status in adolescents (p<0.001). A significant association was also found between physical activity and overweight (p<0.05). This study showed that the adolescents’ use of food delivery applications, fat intake, and physical activity have a significant correlation with their overweight status. However, the type and amount of food ordered did not show a significant correlation. Despite the insight offered, the study was small and limited in one school hence generalization of findings is limited. Thus, a larger study with diverse subjects is needed.

Authors: Warman Mohamad Shakir Eddy , Issa Zuraini Mat
Published: September 2024

This study aims to determine Food Safety (FS) knowledge, practice in preventing Foodborne Disease (FBD), and risk perception related to food handling among food handlers at military bases. An Optimistic Bias (OB) in preventing FBD were examined based on the risk perception responses. A set of questionnaires was sent to an officer at each military base in Malaysia. Later, the officer would conveniently distribute the questionnaire to approximately half of the targeted respondents. A total of 284 data were gathered and were analysed using SPSS version 20. The findings revealed that food handlers had good FS knowledge scores and practice to prevent FBD. However, it was found that different risk perception levels were present, indicating OB. The existence of OB was observed in all comparisons and situations except for the question about sanitising utensils. Hence, a conclusion can be made that there is a tendency that food handlers tend to neglect and overlook FS procedures, and can contaminate foods due to the presence of OB. This study will contribute significantly to military foodservice establishments in Malaysia regarding food hygiene and safety awareness.

Published: September 2024

This study aimed to assess the qualities of butter biscuits made with seaweed flour (Kappaphycus alvarezii, (KA) (0, 4, and 8%) and Overripe Banana Sweetener (ORBS) (0, 50, and 100%) as a partial replacement for wheat flour and table sugar. A.O.A.C. and hedonic methodologies have been used to analyze the nutritional composition, color, and sensory evaluation of butter cookies. The increase in ORBS in cookie formulation resulted in a significant rise in the nutritional qualities of butter cookies, according to the result. Butter cookies with 4% seaweed flour and 100% ORBS had higher total dietary fiber (19.6%) and ash (3.07%) values. Sensory scores for the control (0%) and 4% seaweed flour-incorporated cookies did not differ substantially across all sensory qualities. However, the addition of 4% seaweed flour and 50% ORBS resulted in the highest scores for aroma, flavor, and overall acceptance. In conclusion, substituting 4% seaweed flour for wheat flour and 50% ORBS for table sugar could be an effective combination to make nutritious and tasty butter cookies.

Published: September 2024

Formalin solution can be called a “double-edged sword.” Known for its preservative and disinfectant properties, this aqueous chemical is widely used in the medical field. In dermatology, it is useful in preserving the skin tissue specimen for histopathology. However, if not handled with care, it can potentially cause severe dermatitis, first- or second-degree burns, ulcers in some cases, and even cellulitis. We, here, present a rare unfortunate case of an accidental injection of formalin, instead of a local anesthetic, as a test dose, on the forearm of a 28-year-old man at our clinic and its successful management.
Reversible sulcal fluid-attenuated inversion recovery hyperintensity after combined bypass surgery for moyamoya disease – A “crevasse” sign
Authors: Kashiwazaki Daina , Yamamoto Shusuke , Hori Emiko , Akioka Naoki , Noguchi Kyo , Kuroda Satoshi
Published: September 2024

Background:

Transient fluid-attenuated inversion recovery (FLAIR) hyperintensity is often observed on the operated brain surface after direct or combined bypass surgery for moyamoya disease, but its pathophysiology and clinical significance are still obscure. This study was aimed to clarify the underlying mechanism and clinical significance.

Methods:

This prospective study included 106 hemispheres of 61 patients with moyamoya disease and analyzed their radiological findings before and after combined bypass surgery. This study also included 11 patients who underwent superficial temporal artery to middle cerebral artery anastomosis for occlusive carotid artery diseases as the controls. Magnetic resonance imaging examination was serially repeated, and cerebral blood flow was measured before and after surgery. Signal intensity ratio (SIR) in the cortical sulci and cortex to the adjacent white matter on FLAIR images was calculated, and the postoperative SIR changes were semi-quantitatively evaluated to assess the temporal profile of postoperative FLAIR hyperintensity.

Results:

Postoperative FLAIR hyperintensity occurred within the cortical sulci on the operated hemispheres in all moyamoya patients but not in patients with occlusive carotid artery diseases. SIR values started to increase immediately after surgery, peaked at about 4-fold at 4–13 days post-surgery, then declined, and recovered to baseline values over 28 days or later. The magnitude of this phenomenon was proportional to the severity of cerebral ischemia but not to postoperative hyperperfusion.

Conclusion:

Reversible sulcal FLAIR hyperintensity specifically occurs in the operated hemispheres after direct bypass surgery for moyamoya disease. This “crevasse sign” may represent the mixture of the extensive leakage of oxygen and proteins from the pial arteries into the CSF.

Мониторинг процесса очистки сточных вод при производстве печатных плат предлагается проводить с использованием методов статистического управления процессами. Это позволяет выявить нарушение стабильности и своевременно предотвратить выход контролируемых показателей за предельно допустимые значения. При этом необходимо исследовать степень коррелированности показателей, их нормальность распределения (при необходимости – провести преобразования), выбрать типы контрольных карт для мониторинга, оценить положение их контрольных границ.

Статья поднимает проблемы эволюции музыкальной культуры адыгов, изучения и освоения национальных традиций бесписьменной традиции черкесов (адыгов). Осмысление источниковедческой базы исследований традиционной музыкальной культуры адыгов представляется автору одним из приоритетных направлений адыгской этномузыкологии

Current state of musical culture adyghe markedly different from that developed in the twentieth century. In recent years sharply increased interest in the study and development of national traditions traditional instrumentalism and song art unwritten tradition Circassians (Adyghe). One of the earliest documentary sources are news European authors – «Circassians, Balkar and Karachai Leader European authors XIII–XIX centuries». In their brief review and report on the trip they gave detailed descriptions of the appearance of many traditional musical instruments, as well as recreate the picturesque samples of different genres of Circassian (Adyghe) songs, instrumental tunes, etc. Source base of research instruments, instrumental and vocal traditions gradually began to accumulate that the idea of a special study of traditional musical culture of the Circassians. At the beginning of the collection of ethnographic materials, oral information on the instrumental culture adyghe was general in nature, i.e., going along the way with folk songs, information about traditional clothes, ornaments, history of villages, oral poetry, etc. This work began in 1926 with the fi rst day of the opening of the Kabardino-Balkar Scientifi c Research Institute, which was to conduct fi eld expeditions to collect folk music adygov on the territory of their compact residence. In connection with what were invited musicologists and composers from Moscow. Repeatedly in Kabarda, Cherkessia and Adygea there were well-known musicians. They collected and analyzed a huge actual authentic material. Sayings about bytopisatel Cherkessia Adyghe folk music, and today are of great interest. This explains why research on the material and spiritual culture adyghe included in one of the priorities adyghe ethnomusicology.

Предложен алгоритм минимаксной нелинейной полиномиальной аппроксимации функций преобразования средств измерений, упорядоченный поиск базисов в котором осуществляется по методу Ремеза. Алгоритм состоит из двух частей. Первая его часть предназначена для поиска границ области существования множества оптимальных функций преобразования. При этом из рассмотрения исключаются базисы, которые не могут быть экстремальными, остается лишь необходимый для поиска единственного решения задачи базис. Вторая часть алгоритма осуществляет упорядоченный поиск единственного решения – оптимальной, либо лучшей среди оптимальных функции преобразования.

An algorithm is proposed for measuring instrument calibration equation minimax nonlinear polynomial approximation with search of ordered basis applying Remez method. The algorithm consists of the two parts. The first part of the algorithm is intended for search of existence domain boundary for optimal calibration equation set. While using this part of the algorithm the bases that surely are not extremal are excluded from the consideration, the only basis required for the problem unique solution search remains. The second algorithm part fulfils ordered search of the unique solution which corresponds to the optimal calibration equation or to the superior one among optimal calibration equations.
