An Innovative Approach for Denoising of the Digital Video Stream

Everyday tones of video signals are generated, transmitted, and analyzed. The video contents are created for educational purposes, entertainment purposes, surveillance purposes, medical imaging purposes, weather forecasting, satellite imaging, and many other significant places. During the different phases of video content preparation, transmission, and analysis some unwanted signals get interfered with the true contents. Particularly, the medical imaging signals, since they are weak signals, are more prone to unwanted interferences. Such unwanted interference of the noise signals makes it difficult to analyze the critical information in the video contents and hence, the need for denoising process arises. A decent video denoising framework assures visual improvement in the video signals or it serves as the significant pre-processing step in the video processing steps like compression and analysis. Through this paper, we are about to disclose an efficient video denoising framework that takes the noisy video signal in the form of frames per second and performs the video denoising using shot detection, compensation, intensity calculations, and motion estimation process.

Characterizing the Digital Culture of Prospective Primary School Teachers

This article aims at characterizing the digital culture of prospective Moroccan primary school teachers during their training. The study was conducted as a survey on a sample of prospective primary school teachers from Morocco. A descriptive frequency analysis was performed using SPSS. The results show that this digital culture is rooted more considerably in their personal use of different technological tools or resources. The article analyzes the resources of digital culture through the objectives of digital practices of prospective teachers and the motivations underlying their choice of a specific digital tool and practice. The digital practices of prospective teachers are marked by frequent use of social networks and a low tendency to make use of institutional platforms and their trainers’ blogs. The analysis highlights the nature of the environments, services, and digital resources manipulated by prospective teachers during their training. It also sheds light on the role of this digital culture in the content preparation activities of these potential teachers, as well as the resources produced by them and by their trainers. The preparation of pedagogical content often makes use of social network tools, while educational tools are in average use. Finally, the results show that these exchanges are dominated by WhatsApp, Google Drive, and e-mail; however, the use of the WhatsApp application is more prevalent when interacting with trainers.

Analyzing Safety Communication in Industrial Contexts

Work in industrial contexts is confronted with various risks, which are further amplified by the trend toward Industry 4.0. Approaches are needed to examine safety communication (SC) in such changing environments. Existing studies focus on individual SC means and quantitative evaluation measures. This article proposes a qualitative approach for analyzing SC with which a process chain in a metal-working company is investigated. The results reveal that SC is implemented as a complex system of communicative means. Weaknesses in this system entail several problems at the level of both workplaces and process chains. Due to a lack of digitalization, SC does not meet the requirements of Industry 4.0. Several task areas for communication professionals are identified in optimizing SC. These include content preparation for existing SC means according to work contexts and related tasks, creating digital SC content, and increasing the companies’ resilience to novel risks.

Contract Lifecycle Management

Contract management depends on document-driven processes that, in a paper-based environment, can be laborious and inefficient. The time it takes to approve a contract can be as significant as the content preparation of the contract. Slow, manual contract processing reflects negatively on an organization's ability to provide excellent service. The contract lifecycle is defined differently from an organization to organization or even form department to another. The number of contracts and the associated documents are ramping up in this era of digital transformation. An automated, digital contract lifecycle management (CLM) can reduce the administrative burden on employees and allows legal, financial, sales, and other professionals to make better use of their expertise. This chapter shows how automation can change the organizations' behaviors to view contracts as opportunities for operational improvement and competitive advantage. It shows also how CLM can be integrated with business intelligence (BI) and data analytics systems to provide contract insights and dashboards.

Influence of ICT integration on content preparation by ICT and Non-ICT trained teachers in secondary schools in Machakos County, Kenya

The use of Information Communication Technology (ICT) in teaching and learning has become a necessity and an opportunity for improving and enhancing acquisition of knowledge by learners. The integration of ICT in teachers’ pedagogical practices has the potential to transform the teaching and learning process. ICTs have become vital tools for teachers to enhance learning through the teachers’ pedagogical aspect of content preparation in classroom. The purpose of this study was to investigate the influence of ICT integration on content preparation by ICT and Non-ICT trained teachers in secondary schools. The study’s specific objectives were to assess the status of teachers’ integration of ICT in content preparation and to establish the influence of ICT integration on content preparation by ICT and Non-ICT trained teachers in secondary schools. The hypothesis of the study was; ICT integration does not significantly influence content preparation by ICT and Non-ICT trained teachers in secondary schools in Machakos County, Kenya. The study employed descriptive survey research design. The sample size comprised of 180 principals, 360 teachers and 398 students. Data was collected using questionnaires, observation schedule, and document analysis. Content validity of the research instruments was ascertained through analysis by experts in comparative education and piloting of the research instruments. Reliability was ascertained by testing and re-testing the instruments. Data analysis was done by use of the Statistical Package for Social Sciences (SPSS). Responses from the observation schedule and document analysis guide were organized into themes and integrated with rest of the data for purposes of triangulation. Pearson’s Product Moment correlation coefficient was used to determine the level and strength of the relationship between ICT integration and teachers’ content preparation. Pearson chi test was employed to determine the levels of significance between the variables. The study established that ICT trained teachers profoundly embraced the use of ICT skills to prepare e-based learning activities which enhanced their content preparation leading to more innovative lessons due to the acquisition of pedagogical ICT training. The study concluded that ICT integration significantly influenced teachers’ content preparation by ICT and Non-ICT trained teachers. ICT trained teachers’ integration of ICT in their content preparation was significantly higher at (p) 0.002 than their Non-ICT trained counterparts at (p) 0.045. It was concluded that ICT trained teachers integrated ICT in their content preparation more than Non-ICT trained teachers in secondary schools. Hence the null hypothesis was rejected. Based on the findings and conclusions the study recommended that, The Ministry of Education (MOE) and other ICT training agencies should provide ICT in-service training programs to ensure that all teachers acquire ICT skills to utilize ICT in content preparation for quality education.

O estágio docência e a formação pedagógica na área contábil: Competências docentes adquiridas na pós-graduação

The study aims to identify, in the perception of postgraduate students in stricto sensu Programs in Accounting Sciences (PPGCCs) in Brazil, which competencies are developed in the teaching internship for teaching qualification. The research, with a quantitative approach, had a sample of 296 students who completed the teaching internship between 2013 and 2017. Through exploratory factor analysis, the identified factors explained 71.41% of the variation in the data, indicating a high degree of agreement among the post-undergraduates regarding the teaching skills development in the teaching internship. The identified factors were: Factor 1 – “Competences on Reflection, Research, Planning and Communication in teaching”; Factor 2 – “Skills for Planning, Content Preparation and Application of New Technologies”; and Factor 3 – “Competences in the Evaluation, Organization and Development of Teaching Methodologies”. The contribution of the teaching internship is verified providing that theoretical knowledge and teaching practice can be associated by the student, favoring the necessary skill development for teaching. The study makes it possible to improve the teaching internship, highlighting the need for the guidelines that guide it and clear educational goals, as well as the importance of the student’s supervision by the professor who guides this process.
