Published: March 2023

Purpose: to conduct a comparative analysis of the indicators of chest excursion in students during their studies in higher educational institutions of Bukovyna.

Results. The research was conducted on 126 students of I - II courses of higher educational institutions of Chernivtsi, aged from 16 to 18 years, where 86 (68.25%) were boys and 40 (31.75%) were girls (the main group consisted of 86 (68.25%) students who, in addition to physical activity included in the program of their specialty, additionally engaged in the following sports: football - 42 (48.83%), volleyball - 19 (22.09%), basketball - 13 ( 15.11 %) and handball - 12 (13.96 %), the control group consisted of 40 (31.75 %) students who did not play sports. All students were subjected to an anthropometric study (chest circumference) according to the method of V.V. Bunaka modified by P.P. Shaparenka. The analysis of the breast excursion in the students of the main group showed a significantly higher number with a high level of breast excursion - 27 (31.40%), in contrast to the students of the control group, where there were only 5 (12.5%) with a high level of breast mobility. Conversely, a low level of excursion was noted among students of the main group - 6 (6.98%), while in the control group this indicator was - 8 (20%) of the subjects.

Conclusions. Among the students of the main group, there is a much larger number with a high level of chest excursion - 27 (31.40%), in contrast to the students of the control group - 5 (12.5%). Among the subjects with a high level of chest excursion, the largest number was found in football and volleyball players, slightly less in basketball players, and the smallest in handball players. The index of chest excursion can be taken into account during sports selection and when directing an athlete to a specific type of sport.

The purpose of the study is to reveal the fighting styles of combat sambo athletes based on a multidimensional analysis of psychophysiological and biomechanical indicators.

Material and methods. 42 qualified combat sambo athletes (age 20-25) took part in the study. The biomechanical analysis of the speed of movement of various points and the value of the angles in the joints during a direct impact was used as a research method. Biomechanical analysis of the technique of a direct blow in combat sambo athletes was carried out using the "Kinovea" program, version 0.8.15. The speed of movement of the fist, shoulder joint, elbow joint, and knee joint was determined. The angles between the shoulder and torso (angle in the shoulder joint), between the shoulder and forearm (angle in the elbow joint), and between the thigh and lower leg (angle in the knee joint) were also determined.

Results. 3 clusters (groups) of combat sambo athletes have been identified, which differ in their psychophysiological and biomechanical indicators. The clusters were named as follows: Cluster 1 - "Speed ​​and coordination endurance", corresponds to athletes with a tempo style of fighting; Cluster 2 - "Speed", corresponds to the sportsmen's game style of fighting; Cluster 3 - "Strength and speed", corresponds to athletes with a tempo style of fighting.

Conclusions. The results of this study should be used when planning the individual training of combat sambo athletes and to determine the optimal style of conducting a competitive match for qualified athletes.

Published: March 2023

The purpose of the study to reveal the fighting style of qualified MMA fighters based on the individual factor structure of psychophysiological and biomechanical indicators.

Material and methods. 42 qualified combat sambo athletes (age 20-25) took part in the study. The biomechanical analysis of the speed of movement of various points and the value of the angles in the joints during a direct impact was used as a research method. Biomechanical analysis of the technique of a direct blow in combat sambo athletes was carried out using the "Kinovea" program, version 0.8.15. A psychophysiological method of determining the time of a simple and complex reaction was used in standard conditions and in different testing modes. Using the computer program "Psychodiagnostics".

Results. In the structure of the complex training of qualified MMA fighters, 2 main factors are highlighted. The first factor (55.063% of the total total variance) according to the indicators included in it was named "Speed". The second factor (44.937% of the total total variance) according to the indicators included in it, was named "Speed ​​Endurance". The fighting styles of qualified MMA fighters were identified based on the analysis of the general and individual factor structure of biomechanical and psychophysiological indicators. It is shown that the individual factor structure, which is characterized by the expressiveness of the "Speed ​​and coordination endurance" factor by more than 80%, and the expressiveness of the "Speed" factor by less than 30%, is characteristic of tempo style fighters.

Conclusions. We found 3 groups of athletes, which are characterized by the following manifestations of psychophysiological functions in combination with biomechanical indicators: group 1 - endurance for high-speed and coordination actions; group 2 – speed at short time intervals; group 3 - power (a combination of speed and strength) with a predominance of strength. Determining fighting styles in modern MMA is one of the main steps to improving an athlete and winning.

The purpose of the study is to substantiate the structure and content of the physical training of highly qualified female soccer players during the annual training cycle.

Material and methods. The following research methods were used to solve the tasks: analysis of scientific and methodological and special literature, regulatory documents; pedagogical research methods (pedagogical observation, pedagogical testing, pedagogical experiment); methods of mathematical statistics.

The results. The level of aerobic endurance is determined by the results of the 2000 m run. The obtained data indicate an increase in the test indicators from 499.3 ± 8.24 s at the beginning of the study to 484.7 ± 7.01 s after the basic stabilizing mesocycle, which was 2.9%, but already in the first competitive period, compared to the previous ones , the results of this test deteriorated by 1.0%. In the second competitive period, the test execution speed deteriorated by 2.3%, and the overall average result became even worse than the initial one.

The predominant influence of the development of certain physical qualities on the quantitative and qualitative indicators of the performance of technical and tactical techniques by football players was determined. The number of shots on goal depends on the level of general endurance (r = 0.59), the quality of stopping is dependent on speed and strength qualities (r = -0.53), and the intensity coefficient depends on the level of special (speed) endurance (r = 0.65). There is a very weak or weak statistically reliable relationship between other indicators of competitive activity and physical fitness of qualified soccer players (r = 0.10-0.43).

Conclusions. Based on the determination of the dynamics of physical qualities during the annual training cycle and the analysis of the relationship between indicators of physical fitness and competitive activity, it was recommended to the team coach to plan physical training taking into account the playing role of female athletes and correct training programs with an increase in the time allocated to physical training in the competitive period
RECICLAGEM E SUSTENTABILIDADE: CONFECÇÃO DE BRINQUEDOS COM SUCATA COMO FORMA DE PRESERVAÇÃO DO MEIO AMBIENTE
Authors: Castro Erica Doroteio de
Published: March 2023

Nos últimos anos, com o aumento da população, também tem ocorrido um aumento exacerbado da produção de lixo. Essa é uma grande inquietação, pois não existem por parte das políticas públicas ações que tenham um efeito positivamente satisfatório e maioria da população não se preocupa com os impactos que o atual estilo de vida das mesmas trazem para essa geração e as gerações futuras. Nessa perspectiva, a reciclagem surge como uma alternativa importante para diminuir o acúmulo de resíduos sólidos no ambiente, tornando-se assim, uma atividade que traz benefícios não só para a preservação ambiental, mas também se apresenta como fonte de renda para aqueles que a praticam. A escola é uma porta de entrada para que questões tão importantes como esta ganhe visibilidade e chame a atenção da sociedade. Partindo deste contexto, foi executado na Escola Municipal de 1º Grau de Estiva, interior do Município de Senhor do Bonfim, o “Projeto Reciclagem: quero ajudar o meu planeta”. Esse projeto aconteceu no ano de 2019. Os alunos tiveram a oportunidade de conhecer mais profundamente a problemática da produção e os cuidados que devem ser tomados com o lixo antes de serem dispostos para a coleta. Dentre as atividades que compunham o projeto, aconteceu uma oficina para a produção de brinquedos a partir de sucatas. Sucatas essas que os alunos trouxeram dos quintais de casa, das ruas, das praças (essa foi mais uma ação do projeto, um mutirão da limpeza). A oficina envolveu alunos do 6º ao 9º ano do Ensino Fundamental II e teve como objetivo conscientizar os alunos sobre os impactos causados pela produção e o acúmulo do lixo no ambiente, trabalhando a preservação ambiental e a prática da sustentabilidade por meio da reciclagem. Além de adquirirem conhecimento, na ocasião, os alunos aprenderam novas técnicas de reaproveitamento de materiais que antes não tinham serventia, e a partir de então, tornaram-se produtos usados pelas crianças da escola. Na culminância do projeto, aconteceu uma exposição com os brinquedos que foram confeccionados e os mesmos passaram a pertencer a brinquedoteca da escola.

Published: March 2023

O objetivo deste trabalho foi avaliar o potencial celulolítico de fungos visando a degradação de resíduos lignocelulósicos para a produção de etanol. O potencial celulolítico de 18 cepas fúngicas foi determinado a partir do teste do corante vermelho congo 2,5%, em meio carboximetilcelulose (CMC). Cofermentação do resíduo do caule do mamoeiro empregando o fungo Aspergillus niger e a levedura Saccharomyces cerevisiae comercial foi conduzida por 21 dias a temperatura ambiente. A hidrólise química do caule de mamoeiro com ácido sulfúrico (H2SO4) 0,3% ou ácido clorídrico (HCL) 0,3%, seguida de fermentação pelo isolado Trichoderma sp. ITI07 e Saccharomyces cerevisiae foi avaliada. Os produtos da fermentação foram determinados em HPLC.  Doze cepas apresentaram atividade enzimática, dois fungos apresentaram maior potencial para produção de celulases, Trichoderma sp.  ITI07 e Rhizopus sp.  ITI11. Na cofermentação do caule do mamoeiro com o fungo Aspergillus niger  e a levedura Saccharomyces cerevisiae, o pico de produção de etanol ocorreu com 120 h, com produção de 1,6 g de etanol/L. Nas fermentações utilizando caule de mamoeiro quimicamente tratado com hidrólise ácida, seguido de sacarificação e fermentação simultânea do resíduo do caule do mamoeiro com Trichoderma sp. ITI07 e a S. cerevisiae, foi produzido 1,87  de etanol/L quando o substrato foi hidrolisado com ácido clorídrico e 1,667 g/L com ácido sulfúrico. Dentre dezoito isolados avaliados para o potencial de produção de celulases, doze produzem celulases e as cepas, Trichoderma sp. ITI07 e Rhizopus sp. ITI11 apresentaram os melhores índices enzimáticos. O caule do mamoeiro é um substrato viável para a produção do etanol lignocelulósico, contudo, mais pesquisas devem ser desenvolvidas visando encontrar as condições que levam a maior eficiência no pré-tratamento da biomassa.

Devido à falta de saneamento básico, os efluentes domésticos gerados nas residências das comunidades ribeirinhas são descartados de forma irregular no manguezal o que impacta negativamente neste rico ecossistema. Reunir informações de fontes confiáveis sobre tecnologias socioambientais para o tratamento de efluentes domésticos em comunidades ribeirinhas é importante para a partir disso propor sugestões viáveis que possam resolver esse problema. A fim de auxiliar na solução deste problema em comunidades ribeirinhas localizadas numa região quilombola de Maragogipe-Ba, este trabalho tem como objetivo a elaboração de uma cartilha para informar a população dos riscos do descarte incorreto dos esgotos domésticos nos recursos hídricos e demonstrar tecnologias socioambientais para auxiliar na proteção dos manguezais e recursos naturais. Para tanto, foi realizada uma pesquisa de natureza aplicada com abordagem qualitativa. O processo de pesquisa se iniciou por meio de um levantamento bibliográfico, tendo como critério a credibilidade e a veracidade das fontes, a fim de selecionar os conteúdos e tecnologias socioambientais para serem inseridas na cartilha. A metodologia utilizada para confecção da cartilha foi dividida em 3 fases: 1- seleção e elaboração dos conteúdos que seriam utilizados na construção da cartilha; 2- seleção de ilustrações disponíveis na bibliografia selecionada e imagens produzidas pelo próprio autor que se relacionassem com as informações que estariam contidas na cartilha; 3- montagem do leiaute agrupando as informações com as ilustrações coletadas. O conteúdo foi abordado na cartilha em formato de perguntas e respostas para chamar atenção do leitor e facilitar o entendimento, bem como, em formato de tópicos descrevendo os materiais e métodos necessários para a construção das tecnologias socioambientais selecionadas. O layout da cartilha foi feito no formato digital utilizando a plataforma de designer CANVA. O layout da cartilha foi adaptado a partir de modelos disponíveis na plataforma. O tamanho da folha foi A4 pois nessas dimensões facilita a visualização do leitor. O link gerado pela plataforma permite que o recurso fique sempre disponível para leitura em qualquer lugar, podendo assim também ser compartilhado com outras pessoas. A divulgação da cartilha de forma digital firma a proposta presente neste trabalho fazendo com que este conhecimento chegue à população ribeirinha para que esta possa utilizar desses mecanismos. Com isso, além de estabelecerem uma relação mais sustentável com o ambiente, seguirão cumprindo as diretrizes socioambientais, garantindo a conservação do manguezal e a qualidade sanitária dos alimentos extraídos para o sustento.

Published: March 2023

As práticas conservacionistas do solo e da água tratam-se, de intervenções que contribuem para que a natureza sempre nos dê tudo aquilo que precisamos para viver. Comumente se atribui aos cuidados com os recursos naturais da forma correta e vão além do recurso solo e água, mas também preservar flora, microrganismos, nutrientes, fauna, ar e seres humanos. O solo, basicamente refere-se à superfície da crosta terrestre, que utilizamos para vivemos, construir e, como uma das principais funções, produzir alimentos. O estudo teve por objetivo analisar as técnicas conservacionistas de caráter vegetativo, que prioritariamente utilizam vegetais como ferramenta de proteção do solo, mostra a importância das plantas para qualidade do solo, da água e da biodiversidade. Existem inúmeros métodos de conservação usando as plantas, citam-se: Florestamento e reflorestamento, rotação de cultura, adubação verde, quebra-vento e cobertura vegetal (morta e viva). A influência da cobertura vegetal na perda de solo é o objeto do experimento de campo. Ao realizar um estudo tendo como objetivo mostrar a importância do solo e da água e apresentar as principais práticas conservacionistas destes recursos naturais, tão essenciais para a humanidade, assim como demonstrar as principais práticas e fatores de degradação, desgaste e esgotamento do solo e da água. Foram utilizadas como metodologia pesquisas bibliográficas e experimento de campo com a elaboração da pesquisa experimental, o experimento foi realizado no IF Baiano Campus Governador. Foram utilizados como materiais, 3 (três) vasilhames de água mineral de 20 L cortados ao meio, 3 garrafas pets cortadas ao meio e fixadas por cordinhas para armazenar a água e 1 regador. No primeiro recipiente foi colocado solo e sobre ele uma camada de vegetal vivo, sendo a grama Paspalum notatum Flügge, no segundo vasilhame foi posto solo e sobre as mesmo colocadas camadas de cobertura morta, simulando a natureza, no terceiro vaso apenas preenchido com solo, desprotegido, comumente como acontece nos solos sem práticas de manejo e conservação. Apresentou o melhor resultado o tratamento com vegetal vivo e na sequencia o solo com cobertura morta. Os resultados obtidos apontam o quanto é importante à realização de práticas de conservação dos recursos naturais e como é tão importante reduzir ou zerar as ações de degradação destes recursos, para que no presente e em um futuro próximo não tenhamos crises com escassez de alimentos, falta de água, impactos ambientais e mudanças climáticas.

Published: March 2023

Afloramentos rochosos são reconhecidos como ecossistemas e estão localizados nos topos íngremes das serras e morros. No Brasil, essas formações são bem investigadas na região Sudeste, contudo, são escassos os estudos florísticos e ecológicos desenvolvidos no Nordeste. Portanto esse trabalho objetivou-se realizar o levantamento fitossociológico com o método de parcelas (1m²) da flora e da estrutura de um afloramento rochoso na Serra de Itiúba, Bahia. O material foi herborizado, identificado com auxílio de bibliografia especializada e consultas a especialistas. Para calcular a similaridade foram utilizados os programas estatísticos RStudio e PC-ORD 5. Na análise fitossociológica verificou-se que as espécies com maior valor de importância foram Aechmea aquilega (Salisb.) Griseb. (VI=38,75%), Leptohyptis calida (Mart. ex Benth.) Harley & J.F.B.Pastore (VI=29,02%), Chamaecrista desvauxii (Collad.) Killip (VI=20,4%), Lepidaploa chalybaea (Mart. ex DC.) H.Rob. (VI=18,6%) e Hypenia salzmannii (Benth.) Harley (VI=17,7). O índice de diversidade de Jaccard (J) resultou em J = 2,60 nats/m² e a equabilidade de Pielou (J’) em J’= 0,13. A similaridade foi realizada entre (9) nove áreas de afloramentos rochosos, mostrando que a vegetação da Laje do Céu possui composição florística mais similar à flora dos mirantes naturais no parque urbano de Igatú em Andaraí (BA), e com a diversidade florística em afloramentos rochosos do município de Esperança na Paraíba com aproximadamente 59% de similaridade.
COSMÉTICOS ARTESANAIS, NATURAIS E ECOLÓGICOS A BASE DE MEL E GEOPRÓPOLIS DE ABELHAS SEM FERRÃO
Authors: Sauthier Maria Celeste da S. , Dantas Marília , Sousa Nathalie Araújo
Published: March 2023

O projeto propôs o desenvolvimento de cosméticos naturais produzidos manualmente com à base de mel e geopropólis de abelhas sem ferrão, e outros materiais conhecidos pelas comunidades tradicionais como ervas, sementes e óleos naturais, desenvolvendo materiais de higiene como sabonetes, shampoos e cremes. A proposta é que esses materiais possam ser desenvolvidos com segurança e com poucos recursos, empregando como matéria prima o mel de abelhas de ferrão e outros insumos já conhecidos pelas comunidades tradicionais como ervas, sementes e óleos naturais, tendo o cuidado de seguir os princípios da Química verde e dando preferência a materiais ecologicamente adequados em todas as etapas da fabricação. Essas abelhas têm importância ambiental amplamente reconhecida, principalmente, pelo serviço indispensável que prestam com a polinização, na manutenção dos ecossistemas naturais e agrícolas, e consequentemente, na produção de alimentos. Apesar disso, vem sendo dizimadas pelo emprego de agrotóxicos nas monoculturas e destruição dos seus habitats naturais, entre outros fatores. O mel e demais produtos relacionados são utilizados desde remotas épocas por comunidades primitivas como alimento e remédio, por suas propriedades nutritivas e funcionais. Na primeira fase, foi pesquisado o que já foi publicado em termos de cosméticos à base de mel de abelha sem ferrão para fundamentar a elaboração de um produto seguro e inovador. Essa pesquisa contemplou também o saber tradicional de comunidades ancestrais, que utilizam o mel, além das pequenas propriedades que vivem da agricultura familiar e empregam a agroecologia também na produção do mel. Na segunda fase, foram definidas as metodologias de elaboração dos cosméticos, que foi realizada em domicílio e eventualmente em laboratórios do IF Baiano, Campus Governador Mangabeira. Na terceira fase, foi elaborada uma cartilha, além da conta no Instagram, onde é realizado a sensibilização sobre a preservação das abelhas sem ferrão, assim como a valorização dos saberes tradicionais e ecológicos na produção artesanal e na bioeconomia, que pode substituir com muitas vantagens o consumo desenfreado de substâncias sintéticas, como os derivados de petróleo, muito usados em cosméticos.

Published: March 2023

This research is purposed to know the correlation between vocabulary mastery and reading comprehension at the second grade of SMA N 10 Kota Ternate. There are two variables in this research. Students vocabulary as independent variable (variable X) and Reading comprehension as dependent variable (Variable Y). The population of this research was all second grade of SMA N 10 Kota Ternate while the sample of the research were 30 respondents that taken from class 2 IPA1. This research used convenience sampling and applied quantitative descriptive with Pearson’s r correlation coefficient technique to analyze the data. The data were collected by using a test. The test consist of 30 items of vocabulary mastery test and 30 items of reading comprehension. The result of the research found that there is a significant correlation between vocabulary mastery and reading comprehension is 31.77. While in Pearson’s r table with the degree of significance 5% is 0.367. It means that correlation coefficient of 31.77 is significant and the null hypothesis is rejected because rxy>rt = 31.77>0.367. In other words, the alternative hypothesis that stated there is significant correlation between vocabulary mastery and reading comprehension is accepted. the suggestion of this research is that in developing the vocabulary mastery and reading comprehension teacher should encourage the students to have and use dictionary as a tool to help them with difficult words and the teacher should support the students expectation about reading and arouse their interest to increase their reading comprehension.

Authors: Sibiya Malusi , Didam Markus Elisha
Published: March 2023

Based on LinkedIn poll results, professionals from non-computer science backgrounds have developed an interest in data science and most intend to enter the field through Machine Learning, but do not know where to start (Webb et al., 2021) The aim of this study is to introduce an ideal systematic approach and workflow to get started with Machine Learning. Since the Linear Regression algorithm is the main algorithm used to introduce the concept of Machine Learning, it was chosen for this study to lay a fundamental platform. Using the proposed algorithm and appropriate python libraries, efficient methods of explanatory data analysis and procedural steps towards model training are also explained. Briefly, this study gives an insight on how to approach other Machine Learning algorithms as well. The first steps in Machine Learning involve data pre-processing. The dataset was chosen to meet data manipulation techniques suitable for people without a computer science background.

Text generation is defined as a component of natural language processing that makes use of computational linguistics techniques to produce text that cannot be distinguished from human written text. This study aims to develop and analyse a Generative Pre-Trained Transformer 2 (GPT-2) language model to generate Sepedi phrases. The under-resourced Sepedi language is regarded as a disjunctive language. The Sepedi language orthographic representation presents challenges and has limited resources. The GPT-2 transformer requires large datasets, as well as state-of-the-art computational resources. The unstructured National Centre for Human Language Technology (NCHLT) Sepedi text dataset was used. The text generation model developed with the small dataset managed to get the lowest loss value of 2.36. The output text generated using this model produces a text that is syntactically correct with instances of grammatical errors. The model performed better than previously developed Sepedi text generation models by using transformer-based technique.

Mobile commerce (m-commerce) enables individuals and organizations to buy and sell products on the internet. Despite the growth of m commerce in developed countries, research studies indicate that Small and Medium Enterprises (SMEs) in developing countries are still far behind in adopting m-commerce. The theory of Diffusion of Innovation (DOI) was adopted to underpin the study. A quantitative approach was used in this study. The researcher collected data from a random sample of 150 SMEs in South Africa, in the Limpopo province. The study used structural equation modeling (SEM) to analyze data. In this study, the results of SEM indicate that trialability is the most significant factor in predicting the adoption of m-commerce in South African SMEs. Furthermore, the findings of this study also show that relative advantage, compatibility, complexity, observability and owner/manager characteristics are not significant in predicting the adoption of m-commerce in South African SMEs.
Academic and Skills Credentialing Using Distributed Ledger Technology (DLT) and W3C Standards: Technology Assessment
Authors: Mthethwa Sthembile , Pretorius Morne
Published: March 2023

The ongoing push for the 4th industrial revolution is setting the stage to digitise, persist and verify identity along with credentials. Academic and skills credentials are currently verified manually and have much scope for automation using cryptographic techniques but requires standardisation to facilitate future systems interoperability. The Distributed Ledger Technology (DLT) and World Wide Web Consortium (W3C) Verifiable Credentials (VC) standards presents the possibility to achieve this credential verification automation. To accomplish this, an understanding of various DLTs and requirements for a viable skills tracking system is important. Therefore, this research aims to access the selected DLTs against the assessment criterion presented and an analysis has been completed to determine which DLT is suitable for the proposed system. The DLTs are assessed in terms of their ability to support the rapid prototyping of such a system and provide recommendations to guide a future development path from the perspective of standards compliance. We conclude that few DLTs possess the maturity to provide proper requirements coverage due to the emergent nature of the DLT space. Additionally, this paper presents the high-level requirements to achieve a minimally viable solution that can demonstrate such digital credential verification in the academic and skills tracking context.

Waste management is one of the major problems facing the world today. The trash spillover from garbage/trash/dust bins and the waste handling facilities creates unnecessary waste that needs to be managed. For example, in certain areas, trash spillover generates pollution as well as various hazardous situations. In this regard, unmanaged trash may be the root cause of spreading various diseases as well as creating huge waste management and health issues. To overcome the challenges, as well as maintain public health and cleanliness, this paper proposes the design of an Internet-of-Things (IoTs) based garbage monitoring system that measures the level of garbage in the bins and alerts the relevant stakeholders. It uses an ultrasonic sensor, load sensor, Arduino board, GPS Module, buzzer, and a motor and trash bin (with lid) to design the system. A sensor network was used to collect the levels in the trash bins and remotely trigger the required controls using IoTs. An ultrasonic sensor is interfaced with an Arduino board to check the level of trash and display the data on a dashboard. The administrator will then execute the required notification and dispatch authorized action. In this regard, waste management will be efficient, and overspill managed.

Business aspects such as sales, human resources management (HRM), marketing, accounting, and customer relationship management (CRM) are important for Small and Medium Enterprises (SMEs). Therefore, it is anticipated that SMEs will get to benefit from using innovative technologies (IT) such as Software as a Service (SaaS). SaaS is a Cloud Computing model where applications, resources, and services are provided by the service provider (SP) to SMEs and accessed via the internet. SaaS may transform SMEs. One of the major benefits of SaaS is its dynamic capabilities. Despite the benefits of SaaS, the utilization of this technology in SMEs, particularly in developing countries is still limited. This research study aims to develop a conceptual model for the use of SaaS to improve the dynamic capabilities of South African SMEs. In this study, the theory of Technology-Task-Fit (TTF) will be adopted and used to underpin the study. A positivist research paradigm will be adopted. The study will use a quantitative research approach and data will be collected from 344 SME managers in South Africa using a questionnaire. Structural equation modeling (SEM) will be applied in this study to analyze the data.

Collective behaviour empowers biological species to achieve remarkable swarm level results through distributed actions. For example, social spiders achieve coordinated activities that can lead to plausible outcomes such as preying, mating, or building webs. Developers of simulated swarm systems are increasingly moving away from insinuating individualistic robotic devices, gravitating towards collective swarms to achieve common goals. However, for this to happen, it is imperative to understand the principles that underpin successful simulated coordination of robotic devices in swarms. In this article, we investigate the principles behind artificial swarm systems built on the instinctive behaviours of simulated social spider-like devices (SS-bots). We classify these principles into six interconnected knowledge domains, including (a) environment, (b) SS-bot architecture, (c) SS-bot mission planning, (d) SS-bot communication, (e) SS-bot operators, and (f) metadata and swarm-level data. The key features of each domain are discussed, and an SS-bot ontology is proposed.

The renewable energy power producer (RPP) sector is growing rapidly to become an important source of power in South Africa and in nations across the globe. Companies within this sector provide a variety of clean energy sources. Despite its ability to support the power system and conserve the environment that sustains life, the rising usage of renewable distributed generators (RDGs) poses power quality problems in the overall distribution network, such as the voltage instability at buses, the increase in voltage/current harmonic distortions, etc. Furthermore, RDGs are required to remain connected to the electrical power network during grid faults and provide system support by injecting reactive current when required, depending on the nature of the fault. This study provides a dynamic performance analysis of a doubly fed induction generator (DFIG) based wind energy conversion system (WECS), and permanent magnet synchronous generator (PMSG) based WECS. The potential fault ride-through capability solutions in grid code power generation and injection of reactive power are taken into account, and the application results of both systems are shown under similar working conditions. From the simulation results, it is found that the DFIG based WECS topology performed well compared to the PMSG based WECS topology.
A Framework for the Development of Human Centred ICT4D Initiatives: A Capability Approach Perspective
Authors: Grobbelaar Leon
Published: March 2023

The term “development” is often used concomitantly with Information Technology for Development (ICT4D) and Information Systems for Development (ISD4D) initiatives in discussions related to these fields. Development as an outcome is often pursued through ICT mechanisms without questioning the assumptions about its contribution to human development. Development, as a construct, has been the subject of increasing debate in the ICT4D research community, and is especially fuelled by the current global economic uncertainty. It is when the paradigm of development is shifted away from the predominant Western theory of development, as postulated by many economic development theorists, as well as other development theories, such as utilitarianism, for example, that new development outcomes can be explored. One such outcome is the result of a human centred development approach, where well-being and human development form the focal point of ICT initiative outcomes. The Capability Approach (CA), developed and promulgated by Nobel Prize laureate Amartya Sen, provides an operationalizable framework that views development as human development and having or obtaining certain freedoms. The CA affords the observer the opportunity to assert the social dimension of development and, in the case of this study, that of a rural community in South Africa, with the ICT4D artifact delineated to mobile health, or mHealth.
