Protection of water supply sources from the emergency oil spill on the water surface

The article provides an algorithm for organizing oil spill response on the water surface, as well as the results of the analysis of existing methods of oil and oil product spill response. In order to improve the complex of measures to eliminate oil spills on the water surface, the main requirements for oil-absorbing materials are given. It is shown that the localization and elimination of oil and oil products spills on the water surface due to the destruction of the underwater passage of the main oil pipeline requires a set of works that require the use of various methods and the use of the necessary technical means. The developed set of measures for organizing work in response to oil spills on the water surface and the results of the analysis of existing methods for responding to oil and oil products spills will reduce the time for containment and response to the spill, taking into account the optimal choice of technology for cleaning the coastal strip from oil pollution.

INFLUENCE OF INSTITUTIONAL RELATED ON CHOICE OF TECHNOLOGY FOR THE DEVELOPMENT OF INSTRUCTIONAL MATERIALS FOR DISTANCE EDUCATION

Purpose: no one technology can support all types of teaching and learning at a distance – the most effective approach is to combine a range of technologies. Using multiple technologies ensure that all learning styles are catered for and that significant opportunities for interaction between the learner and the tutor are provided. The general objective of the study was to institutional related on choice of technology for the development of instructional materials for distance education. Methodology: The paper used a desk study review methodology where relevant empirical literature was reviewed to identify main themes and to extract knowledge gaps. Findings: From the study findings, it is concluded that most of learner support services offered to distant learners were not good enough to support the learners effectively. Secondly, the students and the administrators were of the view that there were learner support services that were very vital to distant learners. Thirdly, the students and the administrators were of the general view and in agreement that the learner support services offered were necessary. However, since the students indicated that majority of the services on offer were poor across the institutions under the study, there is need to improve and make them better. Learning through experience influences the creation of new values which become attitudes that have a strong impact on teacher's behavior towards e-learning technology. Recommendations: The study recommends that is a need availability of ICT infrastructure, the absence of inadequacy of which will totally hamper the idea of e-learning adoption in universities. There should be provision of computers and high bandwidth to enable the easy flow of classes online. If the high ICT infrastructure for e-learning is unavailable, the sequential use of predecessor distance learning technologies from correspondence courses to radio, TV, CD-ROM, Internet and World Wide Web is recommended. Such a sequential use of predecessor distance learning technologies is poised to leverage the experience into a significant use of learning

A Comparison of Java, Flutter and Kotlin/Native Technologies for Sensor Data-Driven Applications

As a result of the continuous progress and fast-growing popularity of mobile technologies in recent years, the demand for mobile applications has increased rapidly. One of the most important decisions that its developers have to make is the choice of technology on which their application will be based. This article is devoted to the comparison of Java, Flutter, and Kotlin/Native technologies for applications based on processing and analyzing data from sensors. The main elements of the comparison are the efficiency and resource utilization of mobile applications for Android OS implemented in each of the aforementioned technologies.

When Is Choice Empowering? Examining Gender Differences in Varietal Adoption through Case Studies from Sub-Saharan Africa

This paper examines the question of what makes choice empowering and critiques prevalent approaches to empowerment focused narrowly on agency as the ability of individuals to make their own free choices and act independently. The implications of a narrow focus on agency are illustrated with the examples of technology choice in agriculture, specifically choices involved in the adoption of improved plant varieties. This example elucidates the limits of individual agency and permits an analysis of how choices may be structured to be either empowering or disempowering, with examples from specific plant breeding cases. In view of the importance given to equitable choice of technology for closing the gender gap in agricultural productivity and sustainability, the paper explores what practical steps can be taken towards a balanced approach to empowerment. An approach to designing a new plant variety by constructing choice differently is illustrated, using information on gender relations. The paper derives lessons from the plant breeding cases to inform other kinds of interventions, so that work on how choices are defined is given as much importance for empowerment as creating the option to choose. Agents who exercise power over rules and resources can either reproduce the status quo or innovate; thus, a balanced approach to empowerment requires careful analysis of the elements of choice.

Embarking digital learning due to COVID-19: Are teachers ready?

The COVID 19 pandemic insists schools to close and embark on the digital environment to keep learning to happen. Implementing this learning in educational settings faces challenges related to human resources and infrastructure issues particularly in developing countries. This study investigated the teachers’ readiness in conducting digital learning in Yogyakarta, Indonesia. This exploratory study employed an online questionnaire and semi-structured interviews via either voice calls or video calls to safely gather both quantitative and qualitative data from 62 teachers of 27 different schools in the middle of social distancing regulation in Yogyakarta. The study revealed that the majority of teachers were psychologically, technologically, and pedagogically ready to conduct digital learning. However, the digital learning problem was mostly coming from teachers who teach in rural areas. Students’ technology affordances mainly caused a disparity of digital learning success. The findings suggest that the choice of technology adoption and methodology adjustment can be viewed as a solution to the current digital learning problem. Finally, instead of the teachers’ readiness, the students’ readiness and teachers’ technological pedagogical knowledge are other key aspects of the digital learning success. Thus, these two issues are suggestive for further studies.
