Authors: Chebor Lucy J , Kituyi Lusweti , Andala Dickson
Published: February 2025

Environmental pollution by toxic organic contaminants is a global menace and its magnitude is increasing significantly and so declining water quality has become a global issue. Waste products from the textiles, dyeing, paper and plastic industries are predominantly responsible for contaminating the water bodies. Organic dyes produce toxic aromatic amines that are carcinogenic to human beings and harmful to the environment yet they are non-biodegradable. In an effort to lessen the environmental effects of these dyes, various techniques have been utilized. However, these methods are expensive and ineffective resulting in intensively coloured discharge and high concentration of dyes from the treatment facilities. Nanotechnology is a promising field in waste water treatment. The aim of this study thus was to assess the use of synthesized ZnO nanoparticles in photo degradation of dyes. This involves the degradation of methyl orange dye using sunlight and fluorescent light as sources of radiation on the surface of zinc oxide nanoparticles. The basis of ZnO/UV photo-catalytic process is the semi-conduct optical stimulation of ZnO as a result of electromagnetic ray absorption. Precipitation technique was used to synthesize ZnO nanoparticles. The PXRD results showed diffraction peaks which were indexed to ZnO reference as per JCPIDS file 80-0075. The size of ZnO nanoparticles was found to be 26 nm. FTIR spectra showed a broad band at around 430 cm-1 with shoulder shape, characteristics of Zn-O bond. The images obtained by SEM showed rod shaped clusters of nanoparticles were distributed well within a range of 100 nm which is a favourable property to exhibit better photo catalytic activity. The EDX results showed elemental composition of ZnO nanoparticles and showed 54% Zn, 44.07% O and 1.93% Mn impurities for L1 and 55.34% Zn, 42.3% O and 2.37% Mn impurities for L2. The effect of process parameters like amount of the photocatalyst, initial dye concentration and contact time on the extent of photodegradation has also been investigated.
TVET in Driving Sustainable Development: Strategies for Mitigating Challenges Associated with the Integration of ICT in Instruction of Engineering Subjects
Authors: Saina Andrew Kiplagat
Published: February 2025

Despite the investments on information and communication technology (ICT) infrastructure, equipment and professional development to improve education and training, integration of ICT into classroom learning still poses challenges to teachers, administrators and policy makers. And while the use of ICT creates a powerful teaching and learning environment its benefits of transforming learning and teaching where interaction of knowledge is active, self-directed and constructive, are yet to be fully enjoyed. The impact of rapid technological change and automation on existing skills has led to the identification of strategies for mitigating challenges associated with the integration of ICT in instruction of engineering subjects. Thus this study set out to establish the existing gaps in the strategies for mitigating challenges associated with the integration of ICT in instruction of engineering subjects. The output of this study was to serve as a blueprint for TVET institutions, ICT policy makers, researchers and other education institutions in Kenya to chart the right course of action for the integration of ICT through policy formulation and implementation in achieving the country's strategy of vision 2030 and sustainable development. This research adopted Technology Acceptance Model (TAM) since it is capable of explaining user behavior across a broad range of end-users of ICT. It utilized descriptive research design which allowed a large target population to be directly observed. It targeted 180 trainers/instructors and 12 administrators from the 12 TVET institutions. Purposive and simple random sampling was used to select 12 administrators and 138 trainers/instructors. Interview schedules and questionnaires were used to collect data and frequency and percentage data analysis were used to identify strategies for mitigating challenges associated with the integration of ICT in instruction of engineering subjects. The strategies for mitigating the said challenges associated with the integration of ICT in instruction of engineering subjects were thus established in this research study conducted in TVET institutions within Uasin Gishu County in Kenya. Based on the findings, the study concluded that there is need for the government to support TVET institutions on the strategies for mitigating challenges associated with the adoption and integration of ICT in instruction of engineering subjects.

Authors: Mulati T W , Kyalo N M , Dimo H
Published: February 2025

Technical and vocational education and training (TVET) applies to all forms and aspects of education that are technical and vocational in nature, provided either in educational institutions or under their authority, by public authorities, the private sector or through other forms of organized education, formal or non-formal, aiming to ensure that all members of the community have access to the pathways of lifelong learning. Recently, TVET has become a subject for discussion at summits, academic conferences and at policy circles in most developing countries including Kenya. TVET institutions facilitate the acquisition of the practical and applied skills as well as basic scientific knowledge. However, many research findings have revealed that TVET has been limited on skill acquisition in most countries. On the other hand, the synergy between TVET institutions and industry would greatly encourage and augment a partnership that would result in graduate employability and general skill acquisition. Therefore, this study sought to establish the effect of industry-TVET institution collaboration on skill acquisition. A case study design was adopted in the present study where research questionnaires were randomly distributed to a sample of 712, 104 and 32 students, lecturers and industry supervisors respectively. Findings from the study revealed that practical skill was the main type of skill acquired through the collaboration. Results further showed that majority of the students (over 70%) reported that the collaboration played a role in relevant skill acquisition. Similarly, majority of the lectures and supervisors agreed that the collaboration is of significance in students' skill acquisition. Therefore, the collaboration should be strengthened.
A Review of the Status of TVET Institutions in the Revitalization of the Collapsed Textile Industry in Kenya
Authors: Oluoch George
Published: February 2025

Technical and vocational Education and Training (TVET) is considered a driving force for a sustainable textile industrial development in the world. In Kenya, the industry was one of the major sources of foreign exchange earners for the country in the 1980s. It however collapsed in the early 1990's. It is currently considered in the Government policy "Kenya Vision 2030" as having the potential of reducing poverty by providing employment to more than 8 million people. In its effort to bring to life the collapsed textile industries, the government has revived the Rift Valley Textiles in Eldoret and it is in the process of reviving the collapsed Kisumu Cotton Mills and Mount Kenya Cotton Textiles. Further, concerted efforts are being focused on cotton research especially Bacillus thuringiensis cotton production, at the same time, plans are underway to ban the importation of second hand clothes. However, the government is faced with the challenge of inadequate supply of trained skilled manpower. TVET institutions are expected to play a vital role in the production of skilled labor to facilitate the revitalization of the textile industry in Kenya. In order to determine the status of training in textile and apparel courses in Kenyan TVET institutions, a database of the existing TVET institutions offering textile, and apparel courses was developed. From the database it was established that some vital textile engineering courses were not being offered by any of the TVET institutions. Additionally, it was established that none of the technical universities was offering bachelor's degree in any of the textile-related courses. From the database developed, Jeremiah Nyaga Technical Training Institute was found to offer a diverse range of textile related courses and hence proposed to be considered as a center of excellence in textile training. There is need for regular review of the textile curriculum in conjunction with textile industrial players so as to be at par with the needs of the industry. The paper was based on secondary data and documents obtained from published and unpublished literature sourced from journals, books, papers and the internet. The information obtained from this study is important for the ministry of education in developing policies that will inform a skilled-based curriculum for textile related courses in TVET institutions.

Published: February 2025

The Kenya National Qualification Authority (KNQA) defines Recognition of Prior Learning (RPL) as the process used to identify, assess, and certify a candidate's knowledge, skills, and competencies acquired in non-formal or informal learning, such as work or life experiences, against prescribed standards or learning outcomes. Despite the launch of RPL by KNQA in 2021, its implementation in Kenya, especially Western region, has generally been slow. This study was therefore conducted to: i) To identify key non-formal and informal economy-driving industries with uncertified skilled workers in, ii) To determine the level of need for RPL by Jua Kali workers; iii) To identify the possible RPL processes and nomenclature suitable to MMUST in relation to CBET and, iv) To identify the level of awareness on RPL among stakeholders. The study was done through questionnaires. The first was a needs assessment study targeting eleven '˜Jua Kali' sectors in Kakamega town. These were Mechanical, Electrical, Welding, Masonry, Plumbing, Hotel Services, Carpentry, Textile/Dressmaking, Berber Services, and Hair and beauty services Sectors. The study involved 157 workers spread across the eleven sectors. The study found that 77.7% of the respondents have no certification to prove their competency in the work that they do. A majority (88%) of the respondents would like their skills and knowledge gained informally to be assessed and certified by a recognized institution. Also Out of these, 80.6% reported that their institutions have never been involved in the RPL process and 58.3% reported that their institutions have enough trained personnel to implement RPL. Findings also indicate that there is a high level of RPL need among the workers, at 88%. While reviewing literature from the KNQA, the study found a well laid down policy and guidelines for RPL implementation suitable for MMUST TVET Institute. It further exposes the low awareness on RPL among stakeholders. The study concludes by emphasizing the need to create effective awareness among RPL possible candidates, implementors and policymakers. The study recommends aggressive and effective awareness creation among the 'ua-Kali' traders in the twelve non-formal and informal trade areas as well as among the key stakeholders. Establishing an RPL centre in the MMUST TVET Institute was deemed highly necessary to accommodate the 88.5% 'Jua-Kali' traders in Kakamega town who are willing to have their skills and knowledge assessed and certified.

Published: February 2025

Career aspirations of students may be largely shaped by gender and would make choices on careers to pursue based on the established social orientations. Besides gender, other factors like availability of employment opportunities, guidance and counselling and personal interest in a given field could be important factors driving students to a given university programme. The objective of this study sought to establish the influence of gender on choice of careers in Home Science Education programmes in Kenyan Universities. The study was guided by the Social Cognitive Career Theory that explores how career choices are made. This study used the Convergent Parallel mixed method design. The study was conducted in Uasin Gishu and Kiambu counties in Kenya that have universities with programmes that train Home Science educators. Purposive sampling technique was used to select two universities offering the Home Science Education programmes. The 2 Heads of Department were purposively selected while the 254 students were conveniently selected. Data was obtained using questionnaire, interview schedule and focus group discussion guide. Quantitative data was analyzed and presented using graphs. Qualitative data was analyzed thematically then used to compare with that of quantitative data. The findings of this study reveal that gender played a minimal role among the respondents. The study recommended that policy makers and all stakeholders should offer civic education and sensitization that Home Science Education programme is not a feminine programme. There is need to deliberately showcase men who have ventured and thrived in Home Science and Home Science related careers.
Teaching Factory Concept in TVET
Authors: Ogur Eric Okoth
Published: February 2025

The Teaching Factory concept in technical and vocational education and training (TVET) is an innovative approach to instruction that seeks to provide students with hands-on, project- based learning experiences in a simulated industrial setting. The goal of this research is to examine the feasibility and effectiveness of the Teaching Factory concept in TVET by exploring its benefits, challenges, and limitations. A survey questionnaire was administered to a sample of industry partners, parents, faculty and students to gather information and opinions about the Teaching Factory concept. The survey results revealed that the participants had a general understanding of the concept and viewed it as a valuable approach to instruction. They identified the main benefits of the Teaching Factory concept as providing students with practical skills, preparing them for the workforce, and fostering innovation and creativity. The survey results also revealed that the main challenges and limitations of the Teaching Factory concept are the high cost of equipment and infrastructure, the lack of trained personnel, and the difficulty of integrating the concept into existing curriculum. In addition to the survey, case studies of successful Teaching Factory implementations in TVET were also analyzed to assess the outcomes and impact of the concept. The case studies showed that the Teaching Factory concept was effective in providing students with practical skills and preparing them for the workforce. It also showed that the concept was successful in fostering innovation and creativity, and engaging students in their learning. The results of this research suggest that the Teaching Factory concept in TVET is a feasible and effective approach to instruction. However, the implementation of the concept requires addressing the challenges and limitations identified in this research, such as high costs and the need for trained personnel. Further research is needed to explore the long-term impact and effectiveness of the Teaching Factory concept in TVET.
A Role for TVET in Organizational Training and Development
Authors: Mutebi Ronald , Kiplagat Hoseah
Published: February 2025

Individuals and organizations alike derive benefits from training and development, making the money and time a valuable investment. Thus, on one side is the survival of every organization depending first and majorly on the employees who are the organization's most significant asset and as such must be trained and developed; and on the other side is a TVET system that is today steadily emerging from the shadows of negative public perceptions and an era of being a neglected education sub-sector to finally becoming the mainstream pathway of education and training system in many developing countries. Throughout this oftenchallenging journey, TVET systems have accumulated a vast volume of experience over time that organizations and industry can tap into for own employee training and development programs. This paper therefore reviews relevant literature to define the meaning of training and development in the context of an organization, and whereas most definitions of the two terms have, in the process of defining them, had them mixed up with one another, this paper draws a clear distinction of the two meanings with a table that shows the activities involved in each terminology. The paper discusses the role that TVET systems can play in organizational training and development of many developing countries especially in Africa that are now fully embracing an industry engaged TVET system (employer-led TVET system) and the opportunities therein for TVET systems and organizations. The paper then recommends for development of a regulatory framework that can guide and regulate the entire process from start to end; and a national monitoring system to support the organizational and industry training and development by the TVET systems

Published: February 2025

The pottery industry in Lezo, Aklan is a business that manufactures and sells different pottery products. This qualitative research using a case study approach examined the marketability, sustainability, challenges, and coping strategies of pottery owners. It aimed at ascertaining the profile of the pottery owners and workers, their marketing and adaptive strategies, challenges experienced in the marketability and sustainability of their business, and their coping strategies. The validated researcher-made focus group discussion questions were used to gather data from the 12 participants, nine (9) DTI registered pottery owners, and three (3) workers. Data were analyzed and interpreted using frequency and thematic analysis. Findings revealed that pottery owners and workers were females. Most owners were between 32 to 40 years old. All were married, high school graduates, and had been in the industry for 13 to 19 years. On the other hand, most workers were single, ages 18 to 30 years old, and college level. Owners were selling and promoting their products through displaying in stall areas, posting on social media, word of mouth, cash, installment, and digital/online payment, and mostly having pick-ups and few deliveries. Several challenges were related to the product's marketability, customer demand and supply, customer preferences and satisfaction, and sustainability of business capital, raw materials, and workers' salaries. In response, owners employed coping strategies such as borrowing capital from lending institutions, promoting products on social media, and collaborating with colleagues/workers to increase the volume of products. Despite these challenges, the owners' resilience and adaptability through strategic planning and community support help in the sustainability and success of the pottery industry.

In a cloud system, storage services allow users to store data on the Internet. How-ever, storing data in the public cloud increases the risk of loss, interception, modification,and manipulation by unauthorized users. So, users need to protect their data by applying security mechanisms. In this work, we proposed an efficient hybrid algorithm along with data slicing and integrity verification to improve user-side cloud data security. The proposed hybrid algorithm combines multiple symmetric and asymmetric algorithms to improve both performance and security. It takes the advantages of both to compensate for their weaknesses. The asymmetric algorithm is used for encrypting the symmetric keys, whereas, the symmetric algorithms are used to encrypt and decrypt the data. The proposed framework works by splitting the data into chunks and encrypting each portion separately. File information such as type of algorithm used, hash value, and secret keys are kept at the user’s side enabling only the encrypted data to be sent to the cloud. The proposed hybrid algorithm is evaluated and compared against the-state-of-the-art. The results show that the proposed hybrid algorithm outperformed existing ones in terms of throughput, and running time while achieving better degree of data security

Las grandes infraestructuras son reflejo de los avances de nuestra sociedad, de nuestro desarrollo económico y social. Sin embargo, este desarrollo no puede realizarse a costa de la pérdida de nuestro patrimonio natural, de un modelo que en la actualidad se muestra definitivamente insostenible. Este artículo intenta dar una visión de un nuevo modelo para la planificación y diseño de las infraestructuras, donde la funcionalidad del medio (desde una perspectiva de sostenibilidad) forme parte integrante de los condicionantes inciales del diseño de la infraestructura, de manera que se adapte del modo más armonioso y respetuoso posible al medio natural, tal y como el hombre hizo durante siglos.
El paradigma dominante como obstáculo para la sostenibilidad. La transformación epistemológica y paradigmática de la economía sostenible
Authors:   Universidad del País Vasco, Bermejo Gómez de Segura Roberto
Published: February 2025

Cada vez es más evidente que estamos ante una crisis de la civilización humana provocada por el proceso de colisión de ésta con la naturaleza, lo que significa un peligro para la supervivencia de la especie humana. La causa de que no se haya abortado este proceso es el paradigma dominante y, en especial, los elementos tomados de las premisas que sustentan la economía estándar. Mientras se mantenga el actual paradigma, los centros de poder van a seguir prostituyendo enfoques y conceptos que tienen potencial transformador, y adoptando políticas de sostenibilidad claramente insuficientes. Cuando se manifiestan de forma tan evidente problemas gravísimos como la creciente escasez de petróleo y el cambio climático, las instituciones de gobierno nos anuncian políticas que van a resolver los problemas, sin necesidad de cambiar el modelo económico ni las concepciones que lo sustentan. Sin embargo, la transformación económica inspirada en los comportamientos de la naturaleza y según las premisas de la economía sostenible, debe empezar ya.

In 1999, Switzerland made good its pledge by writing sustainable development into its Constitution. Different strategies and programs are going on to promote Agenda 21-like processes. In July 2005, just 4% of municipalities were involved in the process, though this does represent 29% of the population. In Switzerland, under the country’s federal system, local authorities have for a long time enjoyed considerable autonomy and, under the Swiss system of direct democracy, citizens are able to participate more fully in all political decision-making than in other countries. In the longer term, the aim of the National Sustainable development Strategy is to include sustainable development in all the policies and activities of public authorities.

A propósito de la crisis financiera actual
Authors:   Universidad de Alcalá, Torrero Mañas Antonio
Published: February 2025

La crisis financiera que ya se ha instalado en nuestra sociedad tuvo su origen en las actividades realizadas en EE.UU. por las entidades financieras que idearon e innovaron nuevos productos financieros para trasladar y socializar sus riesgos al resto del sistema. La globalización ha hecho posible que estos riesgos se extiendan por todo el planeta y el problema es el desconocimiento exacto de la situación real de los balances de las entidades financieras. Ello ha provocado una desconfianza general y una falta de liquidez en el mercado interbancario. En este artículo se reflexiona acerca de si la revolución que está teniendo lugar en las finanzas se encuadra en una evolución donde el refinamiento, la sofisticación, y la confianza al suponer mayor capacidad de prever el futuro, no está desencadenando sistemáticamente un aumento de la propensión al riesgo que pueda finalizar en episodios de crisis financiero-económica de una magnitud tal que excediera a la posibilidad de control por parte de las autoridades.

ABSTRACT: 

Prostate cancer is the most common malignant neoplasm among men, with more than 1.4 million cases and 375,000 deaths annually worldwide. Although many cases evolve slowly and remain undiagnosed, in advanced stages the tumor can invade the rectum, simulating primary colorectal neoplasia. The anatomical relationship between the prostate and rectum is crucial for the differential diagnosis of neoplasia, given that both structures share proximity and complementary functions in the urinary and digestive systems. Another relevant factor associated with prostate neoplasia is related to the black race, which has a higher risk of presenting more aggressive diseases, with unfavorable evolutions and often more difficult diagnosis, requiring more laboratory, radiological and pathological investigation. Prostate cancer, commonly asymptomatic in the early stages, requires advanced imaging methods, such as PET/PSMA and magnetic resonance imaging, for accurate staging, especially in intermediate or high-risk cases. Multimodal strategies, combining radiotherapy, hormonal therapy and neoadjuvant approaches, demonstrate efficacy in the treatment of locally advanced cases. Recent studies suggest benefits with second-generation antiandrogens and rigorous local control, highlighting the importance of personalized therapies to improve overall survival. This report addresses a rare case of occult prostate cancer, initially suspected as a primary rectosigmoid tumor due to magnetic resonance imaging findings, highlighting the importance of differential diagnosis for adequate clinical management.

Abstract:

Tuberculosis remains a major public health problem in many parts of the world, with high prevalence and  mortality rates, especially in hard-to-reach regions such as riverside communities in the Amazon. These populations  face significant challenges in diagnosing, treating, and controlling the disease due to geographic barriers, lack of  health infrastructure, and precarious housing conditions. This study aimed to conduct a literature review on the  challenges and strategies adopted for tuberculosis control in riverside communities in the Amazon region, based on  articles published between 2014 and 2024, obtained from the PubMed, SciELO, and Google Scholar databases. The  analysis revealed that tuberculosis is one of the main infectious diseases in these communities, with a high incidence  rate, aggravated by the difficulty in accessing adequate health services and by resistance to treatment, a factor  frequently observed due to abandonment of the therapeutic regimen. The review identified 12 relevant studies that  highlight that the implementation of community health programs, which involve the work of community health agents  and health education, has shown positive results in improving adherence to treatment and reducing mortality. These  programs have been essential in overcoming barriers to access to health services, providing continuous monitoring  and guidance for patients. However, challenges persist, such as the need to better structure health services in more  remote regions, in addition to improving housing conditions and addressing drug resistance. The analysis also  highlighted the importance of strengthening public health policies for these communities, focusing on prevention  strategies, early diagnosis and appropriate treatments. The review concludes that, despite the advances, it is  essential to continue investing in solutions that integrate medical and social care, promoting adherence to treatment  and ensuring universal access to health, so that it is possible to effectively control tuberculosis in riverside  communities in the Amazon and, consequently, improve the quality of life of the affected population.
