Data analysis used the interpretation of logic connected with the context of Islamic Broadcast Communication. The results showed that Citra Progo Radio in the Fajar Indah program used a lecture method with a relaxed nature when broadcasting. The da'i classification in this da'wah broadcast, can be seen from the broadcaster's scientific insights in mastering the Qur'an and Hadith as a source of Islamic law and discipline to carry out their duties as radio broadcast preachers.

Location verification in wireless sensor networks (WSNs) is quite challenging in the presence of malicious sensor nodes, which are called attackers. These attackers try to break the verification protocol by reporting their incorrect locations during the verification stage. In the literature of WSNs, most of the existing methods of location verification use a set of trusted verifiers, which are vulnerable to attacks by malicious nodes. These existing methods also use some distance estimation techniques, which are not accurate in noisy channels. In this article, we adopt a statistical approach for secure location verification to overcome these limitations. Our proposed method does not rely on any trusted entities and it takes care of the limited precision in distance estimation by using a suitable probability model for the noise. The resulting verification scheme detects and filters out all malicious nodes from the network with a very high probability even when it is in a noisy channel.

Heart of Darkness, due to its semantic complexity, interpretative openness and universal thematic interests, has been frequently intersemiotically adapted in a variety of media, encompassing radio broadcast, films, opera, graphic narratives and video games, as well as rewritten in the form of interlingual translations and refracted, with refractions including reviews and critical assessments, but also textual versions radically different from the source text. This article considers selected reinterpretations of Conrad’s text and comments briefly on how in each case the adaptation illustrates a fusion of Conrad’s vision with that of the adapter, hence (trans)fusion, and how this may give a new life to the source text via interpretative shifts. The article presents case studies: the film adaptation – Francis Ford Coppola’s Apocalypse Now (1979), Tarik O’Regan’s one-act chamber opera (both the United Kingdom in 2011 and the US staging in 2015), the graphic narrative by Catherine Anyango and David Zane Mairowitz (2010) and Jacek Dukaj’s Polish language version Serce ciemności (2017). This selection is governed by the variety of media and by the dissimilar approaches of the adapters to their source text. What is evident based on these variants is the role of the adapter as a creative participant in the process of transmitting the ideas of the original text, often updating them to make them relevant to new recipients of various cultural backgrounds. Additionally, reinterpretations and recontextualizations of the novella result directly from adaptive strategies specific to a given medium.
