“…Sá-Pinto et al ( 2021) described a framework to assess school curricula according to whether the students address the ideas, concepts, and mechanisms that are necessary to understand evolution. However, since the diversity of the APEC documents in terms of their extension and arrangement was high (Alonso et al, 2015), the 'text mining' technique (Kaushik & Naithani, 2016) was selected to assess a global analysis.…”

Evolution by natural selection is a theory that constitutes a powerful paradigm capable of conveying the teaching-learning of multiple concepts in biology. However, it has been controversial from its formulation to the present, which also affects education. For instance, while some of the basic curricula of primary education in Europe are arranged around the concepts that are considered necessary for structuring the scientific model of evolution (i.e., Sweden), other curricula do not contemplate such concepts. The last is the case of the basic curriculum of primary education in Spain. However, in Spain, on the basis of such a curriculum, there are 17 different primary education curricula corresponding to each of the autonomous communities of the state. The objective of this work is to state a detailed geographical picture of the presence of the concepts necessary to articulate the model of evolution through the analysis of the autonomic curricula of Spain. With such an aim, words that represent such concepts (evolution, inheritance, selection, adaptation and biodiversity, etc.) have been searched for in the natural sciences and social sciences areas of the autonomous curricula of primary education. Furthermore, a search for such evolution-related concepts has also been performed in the activities of eighteen Spanish primary education textbooks on natural and social science subjects. For this purpose, two aspects were considered: characterisation and scientific skills. Both the autonomous curricula of primary education and the textbooks hold important gaps when addressing evolution. The texts include activities that prioritise basic cognitive skills over the more demanding ones associated with scientific competence.

“…Confidentiality of precious data can be achieved using cryptography techniques [1][2][3][4][5][6][7][8]. Cryptography is the art of developing and implementing algorithms to encrypt message in such way that it will be impossible for unintended and unauthorized persons to process or reveal the contents of it whether it is in transmitting or storing state.…”

Abstract-Encryption is a way to secure and verify data that are traded through public communication channels in the presence of intruder party called antagonists. Consequently, the transmitted or stored message can be converted to unreadable form except for intended receivers. The decryption techniques allows intended receiver to reveal the contents of previously encrypted message via secrete keys exchanged exclusively between transmitter and receiver. The encryption and decryption techniques can be applied equally to a message in any form such as text, image, audio or video. The current paper applies and evaluate two different encryption/decryption algorithms to the real-time audio signal. The first one is the well-known RSA encryption and decryption technique, while the second one is a new suggested algorithm based on symmetric cryptography concept. The Matlab Simulink simulator tool is used for acquiring the real-time audio signal and simulating the proposed algorithms. Considering the mathematical nature of the audio signal, the experimental results showed that the RSA method yields an audio signal with low quality while the suggested algorithm yields audio signal with high quality as exact signal as the original one.

Video steganography is a technique to hide different types of files (secret massages) into a carrying video file. Video files contain a collection of images (frames) and sounds, so most of techniques that apply on images and audio files can be applied to video files also. The large amount of data that can be hidden inside the video and the fact that it is a moving stream of images and sounds gives the cover video files great advantages. In this paper, we present a proposed video steganography algorithm in the frequency domain. It was applied to two datasets to study the effect of selecting red, green and blue band on the quality of stego images. From the results we found, the quality of the stego images after data embedding into red channel, green channel and blue channel depends on the nature of the dataset.
