This paper presents an electronic system aimed to assist on the postural evaluation by measuring the weight distribution on the feet. Postural evaluation is commonly used by physiotherapists in order to correct muscle-skeletal problems such as those derived from ageing, accidents, diseases, etc. The developed electronic system was validated preliminary using video cameras to confirm the correct postures of the subject under test. With the obtained data it is possible to corroborate that the proposed system is capable to assist on the correction of the postural position in real time. The main limitation of this work is the reduced number of tests, due to this only preliminary results are presented. The main novelty of this work is the proposed solution to evaluate and help to correct the posture by using a portable electronic device based on force sensors. Derived from the presented results it can be concluded that the proposed system is capable to assist on the evaluation and correction of postural position in real time. [ABSTRACT FROM AUTHOR]

The use of electronic devices and resources in the classroom is part of the daily activity for lecturers and students, and it meets the requirements of the "longlife learning" advocated by the EHEA. Thus, several studies have explored the importance of interaction through social networks, using blogs and other electronic resources. Some lecturers have also conducted various experiences related with the use of those devices that allow access to these technologies. The influence of communication technologies provides clear advantages for both the learning process of students and for the daily work of their teachers. However, there are many risks and disadvantages resulting from such use. This article proposes an initial investigation to determine the extent of computer use in the classroom between students degrees in Communication. [ABSTRACT FROM AUTHOR]

One of the plagues intercepted by the Health's supervisory Service of Animals and Plants (APHIS) of United States in the exports of some species of flowers of court of Colombia is Copitarsia spp. The present study evaluated the evasive answer of Copitarsia decolora (Lepidoptera: Noctuidae) by means of the simulation of calls of echo-location of bats as a proposal for the handling of flowers in post-harvest rooms, under controlled conditions. The shapes of the signs of echo-location of the bats were taken from some samples of insectivorous quirópteros and were simulated by means of the software "Sound Ruler", determining the fundamental parameters that characterize the calls, such as their width, frequency and forms, among others; starting from this characterization, an electronic system was designed and built to reproduce the echo-location calls. The system was tried, emitting the reproduced signal toward a sample of Copitarsia, and an evasive reaction was observed as result of this signal. [ABSTRACT FROM AUTHOR]
