Employing wireless networks in enhancing occupational safety at the developing seaport – two proposals

Bauk S., Schmeink A., Colomer J.

Polish Maritime Research

2017

nr 1

115--124

The paper proposes two Wireless Body Area Network Sensors (WBANSs) scenarios at the logical and simulation levels for improving occupational safety and health conditions at the developing seaport environment. The Port of Bar (Montenegro) is taken as an exemplar. The logical model is based on the actual position of the Port of Bar at the seaport market, its needs and capacities for the information systems innovation through technology transfer and diffusion. The simulation model analyses the channel between the body central unit (BCU) of the worker’s on port wireless body sub-network and the port access point. The quality of the signal transmission at the physical layer has been tested through a source code generated in the Matlab. The code includes the BCU composite signal modulation, transmission, and demodulation, along with a noise and fading effects analysis. The results of the simulation experiments for the different transmission frequencies and distances between transmitter (worker’s BCU) and receiver (port’s access point) by using binary phase-shift keying (BPSK) and quadratic phase-shift keying (QPSK) modulation schemes are presented. Some directions for further investigations in this field are given, as well.

Teaching ECDIS by Camtasia Studio: Making the Content more Engaging

Bauk S., Radlinger R.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2013

Vol. 7, no. 3

375--380

The basic idea of this paper is to motivate teachers/instructors of maritime schools and colleges to create interesting and engaging screencasts for teaching students (future seafarers) ECDIS basis, by using new contemporary media and didactical solutions. Camtasia Studio has been proposed as suitable applied software for doing so. It is a multi-media, user-friendly environment, providing the customers with the variety of possibilities for editing PowerPoint presentations with the introduction of audio, video and different animations, in order to make teaching/learning content more interesting and to point out the most important issues. It allows computer screen video capturing, and adding of audio and numerous animated effects to it, as well as augmenting video recordings into the Camtasia project(s). Even though the proposed software tool possesses a broad palette of advanced features for recording and editing “lively” and edifying recordings, within this paper only brief descriptions of “reviving” classical PowerPoint presentations, taking the screen captures over Transas demo ECDIS software, and their editing is presented. Several examples of instructional recordings concerning ECDIS operational basis, and possibility of students’ self-evaluation have been given, too.
