"Communication is a dynamic field and constantly moves in the direction of human civilization. Communication were initially confined to the study of rhetoric and persuasion, in the modern era has been transformed into an interdisciplinary field, that explicitly challenging all forms of conventional boundaries, both theoretically and methodologically. Today, with the development of digital technology, the media landscape has changed, new media has been dominating all areas of human life, trends in communication studies then shifted towards new media, which more likely to interactive and two-way. This study will conduct an analysis of the historical development of communication studies, as well as a variety of contexts underlying the development of communication studies. By understanding the evolution of communication studies, we can learn how each era in history seeks to systematically solve mysteries in communication. It becomes essential to examine further, considering that the theory and methodology of communication is not something that comes in a vacuum. He emerged from the negotiations in the dialectic of human history. Thus, any historical development will bring new themes in the study of communication, and this study will look at it chronologically."

Biofilm is a structured formed by a community of microorganisms that are bound to each other and fixated by adhering to a surface in the extracellular polymer matrix produced by these microorganisms. Biofilm formation has been reported high in tracheostomy cannule and related to chronic inflammation, as well as infection with antimicrobial-resistant microorganisms. There are several biofilm detection methods, including Microtiter Plate Assay (MPA) Method, Congo Red Agar (CRA)iMethod, and modified Congo Red Agar (modified CRA) Method. This study is a diagnostic study with cross sectional design that aims to evaluate the diagnostic performance of bacterial biofilm detection by CRA and modified CRA method, which are considered easier and simpler than MPA method, which is considered as the gold standard. Bacterial biofilm detection using CRA, modified CRA, and MPA method in this study was carried out on 100 bacterial isolates obtained from tracheostomy cannule swab cultures of adult patients at Otorhinolaryngology Outpatient Clinic Dr. Cipto Mangunkusumo Hospital in June-July 2020. Bacterial biofilm formation was detected by 25% based on MPA methods with the most bacterial constituent is Pseudomonas aeruginosa. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of CRA methods were 36%, 63%, 24%, 75%, 56%. Modified CRA method did not have a better diagnostic performance than CRA method, with sensitivity, specificity, NPP, NPN, and accuracy were 52%, 35%, 21%, 68%, 39%. The concordance of interobserver bacterial biofilm detection using the CRA and modified CRA methods was found to be very strong (Kappa 0.927, p = 0.035 for the CRA method and Kappa = 0.856, p = 0.042 for the modified CRA method)"
