Son yıllarda küresel ısınmaya bağlı olarak yaşanan mevsimsel kuraklıklardaki artışlar, su kaynaklarının azalmasına neden olmakta ve kullanılabilir suyun tüm alanlarda daha etkin bir şekilde tüketilmesini gerektirmektedir. Tarımsal amaçlı değerlendirilen suyun, özellikle kentsel açık yeşil alanlardaki bitkilerin sağlıklı gelişimi ve sürdürülebilirliği kapsamında farklı peyzaj tasarım anlayışları gündeme gelmiştir. Bu tasarım anlayışlarından biride, az su isteyen bitkilerin yanı sıra doğal türlere öncelikli yer verilmesi ile benzer su isteğine sahip bitkilerin tasarımda bir arada değerlendirilmesi sonucu suyun etkin kullanımını benimseyen kurakçıl peyzaj yaklaşımıdır. Araştırmaya konu olan Kültür Park’ın alan kullanımları çıkartılarak, mevcut süs bitkilerinin kurakçıl peyzaj ilkeleri doğrultusunda su tüketimleri, kurağa dayanımları ile park alanının su kullanımı ve etkinliği değerlendirilmiştir. Elde edilen bulgular doğrultusunda; sürdürülebilir yeşil kent dokusunun oluşturulmasına katkıda bulunmak amacıyla kurağa dayanıklı, bölge ekolojisine uygun alternatif bitki türleri ve sulama ile ilgili öneriler sunularak yapılması planlanan diğer kurakçıl peyzaj çalışmalarına öncülük edileceği düşünülmektedir.

The primary real estate market has shown systematic growth since 2020 due to the stimulating demand by using mortgages with state support, as well as the availability of a project financing instrument that protects the buyer from the risks of losing money invested in shared construction. At the same time, the current unstable economic situation leads to a drop in demand caused by a decrease in purchasing power and rising inflation. This dynamics primarily indicates an increased number of proposals, a high level of competition and the risk of oversaturation for developers. In the current conditions the gap emerging in the real estate market between the existing supply and real demand will only increase, which will require developers to use tools and management solutions aimed at promoting the product in the real estate market and building effective personalized communication with clients. The success of marketing tools depends on companies' focus on consumer sentiment, behavior and preferences. The presented work analyzes the civil construction industry's best practices for interaction with buyers, taking into account their emotions, expectations and concerns.

Published: October 2024

In the conditions of a modern market economy and constant social transformations, the issues of formation and rational use of human capital are becoming particularly relevant. An important aspect is to consider the role of older workers with unique knowledge, experience and skills in improving the competitiveness of organizations. The article focuses on the importance of older employees in solving the problem of shortage of qualified personnel. Theoretical approaches to the analysis of the competitiveness of older workers, including classical, institutional and systemic approaches, are considered. An important place is occupied by the concept of decent work, which implies fair pay and working conditions, as well as equal opportunities for professional growth of older workers. The text emphasizes the importance of involving older workers in economic activities, their role in mentoring and transferring knowledge to the younger generation, which contributes to the development of the organization's human capital. The manifestations of gerontological ageism — age discrimination — in the labor market and in social and labor relations are discussed. In conclusion, it is emphasized that the preservation and development of the labor potential of older workers is not only a socially important task, but also a strategic resource for increasing the competitiveness of the company in the long term.

Published: October 2024

Integration of Virtual Reality (VR) in education is increasingly recognised for its potential to enhance immersive learning environments, especially for at-risk students facing challenges like insecurity and inadequate infrastructure in Sokoto State, Nigeria. The study applied virtual reality in teaching STEM subjects (Science, Technology, Engineering and Mathematics) and explored how it improved engagement in learning, interest in laboratory practicals and educational outcomes for at-risk students, guided by Albert Bandura’s Social Cognitive Theory (SCT). A mixed-method approach incorporated qualitative observations and a quantitative quasi-experimental design. The study assessed the impact of VR-based instruction on at-risk students compared to traditional teaching methods. A sample of 65 students was divided into an experimental group (n=31) receiving VR-based instruction and a control group (n=34) with traditional instruction. Data analysis involved pre-test/post-test comparisons, descriptive statistics, and t-tests. Results revealed that VR-based teaching significantly improved students’ engagement, learning outcomes, and interest in hands-on skills. The experimental group showed higher participation, on-task behaviour, and satisfaction, and achieved better post-test scores in complex subjects such as Human Anatomy and Trigonometry. The study concluded that virtual reality (VR) technology effectively enhances STEM education for at-risk students at the secondary school level engagement with scores increasing from 3.5/5 to 4.6/5, significant improvement in performance with a mean gain of 33.4 points, and an increase in interest for the Hands-on laboratory practicals from 3.5 to 4.6. The study recommended the integration of virtual reality technologies into the secondary education curriculum. Further research should focus on translating immersive experiences into academic performance, emphasising on teacher training and support.

Published: October 2024

Unemployment is a global problem as across the world no Country is untouched with this problem this is a basic problem which affects the development of any country and a challenge to every government. In India also Unemployment can be seen at every stage and in every age group of people due to one or other reasons. Although all types of employment prevail in our country yet unemployment after higher education is a big issue to deal with. This paper focussed on the growth of universities and colleges, enrollment of students in higher education as well as studying the gap between degree holders and job holders. Secondary sources like data and Statistics from the internet like census CIME report, newspapers, Higher Education Profile 2018-19 and 2019-20, a report on higher education by Ministry of Education Government of India etc, UGC Annual Report (2019-20) were used to collect data. On the basis of empirical data analysis method, it was found that although the number of educational institutes as well as students in higher education increased at a high speed at all levels i.e. Ph.D., PG and UG during 2016-20, yet there is a huge gap between UG/PG and PhD degree holders and job holders Thus, many eligible citizens of our country are able to find the jobs suited to their eligibility. Manishsiq (2023), Khamo (2023), Anusree and Gangadharan (2022), Agarwal (2019), Das and Paul (2018) also revealed in their studies that increase in education resulted in decreased unemployment and found that excess supply of educated graduates, rapid enrollment expansion, lack of skills and low quality of education are the reasons for this mismatch.

The purpose of this study is to investigate the role of religion in mitigating climate change within selected church-sponsored Secondary schools in Tigania West Sub-County in Meru County- Kenya. The objectives of this study were: to assess how environmental education is integrated into the curricula of church-sponsored Secondary schools in Tigania West Sub-County of Kenya, explore the influence of religious teachings on attitudes and actions toward climate change, examine community engagement in environmental initiatives, and identify both the barriers and opportunities for promoting environmental sustainability within these institutions. Specifically, the study seeks to examine how religious teachings, values, and practices influence environmental stewardship and promote sustainable behaviors in these schools. By exploring the intersection of faith and environmental responsibility, the study aims to uncover the potential contributions of religious institutions in addressing climate change challenges at the community level. Religion plays a crucial role in shaping the beliefs, values, and behaviors of individuals towards their environment. However, the role of church sponsored secondary schools in training individuals on environmental care is not well documented. The study was conducted in 3 selected church sponsored Secondary schools in Tigania West Sub-County in Meru County of Kenya. It adopted a descriptive survey design where a total of 25 respondents constituting of 19 teachers, 3 principals and 3 sponsors of selected secondary schools were targeted. Stratified random sampling technique was adopted where questionnaires and interviews were used to collect data. Th findings showed that the church played a great role in instilling moral values on students. However, little is known about their role in climate change mitigation. Therefore, this study highlights a potential gap in the education. This study recommends the need for religious institutions to rethink their educational priorities and consider incorporating teachings on climate change mitigation into their curriculum. This will play a vital role in shaping the attitudes and behaviors of students towards environmental stewardship and fostering a sense of responsibility towards environment. Religion plays a vital role in addressing climate change by inspiring action, advocacy, and providing a moral foundation for decision-making. This influence can foster positive societal change.

Authors: Muhammad Aliyu , Baban’ umma. Dr. Mohammed Bello , Abdul Dr. Abdullahi Mohammed
Published: October 2024

In recent years, the Nigerian government has intensified efforts to address food security challenges by implementing various initiatives aimed at encouraging local food production and restricting the importation of certain agricultural products, such as rice produced abroad. However, the implementation of these policies faces significant challenges. This study examines the obstacles to implementing the ‘Anchor Borrowers Rice Programme’ for small holder rice farmers in Nasarawa State, using the Diffusion of Innovation Theory as a theoretical framework. Employing a survey research design, the study gathered primary and secondary data through questionnaires, interviews, and a literature review. The analysis revealed that while the programme has effectively increased rice accessibility, several barriers persist. Environmental challenges, including climate variability and pest infestations, pose substantial risks to crop yields. Inadequate funding limits the resources available to farmers, leading to disruptions in agricultural cycles and reduced yields. Additionally, infrastructure and logistics issues, along with administrative and bureaucratic problems, further complicate program execution. To address these challenges, it is recommended to allocate sufficient funding and resources to the programme, including increasing initial capital for farmers and ensuring the timely disbursement of funds. Investing in sustainable agricultural practices and financial support mechanisms, such as promoting drought-resistant crop varieties, implementing water management strategies, and providing access to weather forecasting services, may help mitigate the adverse effects of climate variability and pest infestations. Furthermore, enhancing coordination between government agencies, financial institutions, and other stakeholders can streamline administrative processes and improve programme delivery efficiency.

Elliptic curve cryptography involves numerous scalar multiplications, incurring high operational costs. In view of this, fast endomorphism is used to represent scalar multiplications, kP on elliptic curves. In the past, techniques such as Gallant-Lambert-Vanstone (GLV) method and Integer Sub-Decomposition (ISD) method have been proposed to reduce the cost of scalar multiplication on elliptic curves by using fast endomorphism. The GLV method employs a single-layer decomposition, breaking k into k1 and k2, while the ISD method uses a bilayer decomposition. The existence of fast endomorphisms which are constructed based on the concept of isogeny increase the computational efficiency of the GLV approach and reduce the operation count on the ISD method. This paper embeds the fast endomorphisms in the scalar multiplications on one of the family of elliptic curves with j-invariant 0, E0, which is the 192-bit Koblitz curve (Secp192k1). The performance of the ISD method in computing certain scalar multiplications on Secp192k1 in conjunction with fast endomorphisms and other various techniques such as binary representation, NAF representation, w-NAF and sliding windows are computed. The results demonstrated that the ISD method together with fast endomorphism, yields the most promising outcomes. This underscores the advantages of using fast endomorphisms in the ISD method on E0.

Pseudomonas aeruginosa is a bacterium that commonly found in various environments, including food, soil, and water. The significant concern is it’s resistance to many antimicrobial agents and it’s role in the spread of antibiotic resistance genes. This study investigated P. aeruginosa contamination in food products in Ho Chi Minh City and found the following contamination rates: pork (44.8%; 13/29), beef (38.5%; 10/26), fish (30.0%; 9/30), chicken (25.9%; 7/27), street drinks (25.9%; 7/27), shrimp (17.9%; 5/28), raw milk (10.7%; 3/28). The highest average quantity of P. aeruginosa contamination was observed in beef samples, with over 104 CFU/g, while shrimp samples had the lowest, nearly 103 CFU/g. Among the 94 isolates examined, 63 were sensitive or showed intermediate resistance to ten antimicrobial agents. Resistance was observed in 32 isolates, with the hightest resistance rates to aztreonam (28.9%), followed by ciprofloxacin (11.7%), and gentamicin (2.1%). The antimicrobial resistance rates of P. aeruginosa isolates varied by food type: pork (27.6%), fish (16.7%), shrimp (10.7%), chicken (7.4%), street drinks (7.4%), and beef (3.9%). All P. aeruginosa isolates from raw milk were sensitive to the tested antimicrobials. The findings suggest a need for stricter regulations to control P. aeruginosa contamination in food products. Further research is also recommended to explore the potential for transmission of drug resistance genes from P. aeruginosa in contaminated food.

Digital transformation: A roadmap to leverage businesses for SMEs
Authors: Denmamode Leila , Panchoo Shireen
Published: October 2024

COVID-19 has been a critical turning point for businesses worldwide, compelling them to adopt digital technologies to sustain their economic activity. However, with limited resources such as budget constraints, transforming business strategies to integrate digital technologies is tedious. As the global market continues to evolve into a dynamic digitalised landscape, adopting digital transformation has become essential for businesses, especially start-ups and small- and medium-sized enterprises (SMEs), to remain competitive. Consequently, this study presents a roadmap for start-ups and SMEs to guide them in looking for support in digital technologies to leverage their businesses. The methodology includes a review of the industry’s best practices and case studies based on successful implementation, while fostering a customer-centric approach. Visits to trade fairs and interviews with small business owners were conducted (1) to understand the challenges faced by SMEs and (2) to identify their need to use digital technologies. The results show that one of the main challenges SMEs face is that apart from the lack of proper infrastructure, they lack confidence in adopting technology in their business. They require knowledge of digital technologies to properly define their requirements and use digital platforms. A framework mapped on the hierarchy of effects model is proposed to assist SMEs embarking on digital transformation systematically to learn, adapt, evolve, and sustain their businesses based on their needs and pace. This research contributes to the strategic roadmap, which provides step-by-step guidelines to support SMEs that could be part of their respective countries’ economic growth.

Conselhos de fiscalização profissional no Brasil, autarquias sui generis, e a Lei-quadro das associações públicas profissionais de Portugal: estudo comparado
Authors: Oliveira Weder de
Published: October 2024

Os conselhos de fiscalização profissional são autarquias sui generis, destinadas a fiscalizar o exercício de profissões. No Brasil, estão envoltos em questões ontológicas controversas e a legislação de regência é antiga, fragmentada e casuística, inadequada para lidar com os problemas complexos dessas entidades. Os conselhos têm sido pouco estudados quanto à sua estruturação federativa, organização, gestão, mecanismos de controle, accountability, ação regulatória e cumprimento das finalidades de interesse coletivo. O tema foi recentemente reavivado pela Proposta de Emenda à Constituição 108/2019, por decisões do Supremo Tribunal Federal e do Tribunal de Contas da União. Tendo como contexto teórico a autorregulação profissional e por objetivos encontrar subsídios para a disciplina jurídica, a organização, a governança e o controle da atuação dos conselhos, o artigo promove, em aspectos selecionados, uma análise comparada da legislação brasileira com a lei-quadro das associações públicas profissionais de Portugal, e conclui que a legislação portuguesa, que avançou na direção de definir o direito aplicável e de equilibrar o interesse coletivo com os interesses gerais das profissões, ambos presentes num modelo de autorregulação, constitui um paradigma relevante para orientar o aprimoramento normativo e funcional do sistema brasileiro.
