Many methods exist to achieve this purpose, yet not all of them can produce results with high detection ratios. Some may have high complexity, and others may require numerous inputs. Therefore, a new multi-phase algorithm that depends on information theory is introduced in this article to detect the edges of aerial images adequately in a fully automatic manner. The proposed algorithm operated by utilizing Shannon and Hill entropies with specific rules along with a non-complex edge detector to record the vital edge information. The proposed algorithm was examined with different aerial images, its performances appraised against six existing approaches, and the outcomes were assessed using three image evaluation methods. From the results, promising performances were recorded as the proposed algorithm performed the best in many aspects and provided satisfactory results. The results of the proposed algorithm had high edge detection ratios as it was able to capture most of the significant edges of the given images. Such findings make the proposed algorithm desirable to be used as a key image detection method with other image-related applications.","PeriodicalId":39396,"journal":{"name":"International Journal of Information and Communication Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78787819","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper represents a model that accounts for the detection of botnets through the use of machine learning algorithms. The model examined anomalies, commonly referred to as botnets, in a cluster of IoT devices attempting to connect to a network. Essentially, this paper exhibited the use of transport layer data (User Datagram Protocol- UDP) generated through IoT devices. An intelligent novel model comprising Random Forest Classifier with Independent Component Analysis (ICA) was proposed for botnet detection in IoT devices. Various machine learning algorithms were also implemented upon the processed data for comparative analysis. The experimental results of the proposed model generated state-of-the-art results for three different datasets, achieving up to 99.99% accuracy effectively with the lowest prediction time of 0.12 seconds without overfitting. The significance of this study lies in detecting botnets in IoT devices effectively and efficiently under all circumstances by utilizing ICA with Random Forest Classifier, which is a simple machine learning algorithm.","PeriodicalId":39396,"journal":{"name":"International Journal of Information and Communication Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77694821","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following this developing thread, this work examines discourse within r/coronavirus, a Reddit forum (i.e., subreddit) developed to curate COVID-19 information that burgeoned during the early months of the pandemic. Through a content analysis of 226 posts and 2260 corresponding comments generated between February and May, 2020, this study investigated early-pandemic communication patterns in this platform, including what information was deemed important and how users framed causes and solutions. Overall, findings indicate that users of r/coronavirus prioritized information about COVID-19 spread, public health information (e.g., mask mandates), political and economic implications of COVID-19, and the experiences of medical workers, while also shaming people who failed to follow public health guidelines. Discourse was collectivistically oriented and negatively valenced, and engagement with the subreddit decreased over time, suggesting COVID-19 fatigue among r/coronavirus users. Taken together, this study provides a window into early pandemic discourse, furthering our understanding of COVID-19 communication in early 2020 and revealing informational needs that could be targeted during future health emergencies. Furthermore, progressive fatigue in r/coronavirus (i.e., decreasing curational motivation) showcases a difficulty facing public health communicators during a pandemic’s emergence.","PeriodicalId":39396,"journal":{"name":"International Journal of Information and Communication Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89504138","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consumers who use VR are often able to simulate authentic experiences that feel “real-life” (Diemer et al., 2015). VR experience has also been associated with the characteristics of immersion, presence, interactivity (Mutterlein, 2018), and vividness (Van Kerrebroeck et al., 2017). Novelty and first-time VR use have been investigated to some extent in research on education (Adams et al., 2009; Merchant et al., 2014), but VR novelty has not been studied in-depth in other disciplines. This study takes a phenomenological approach, which uses in-depth descriptions of participants’ experiences of a real-life phenomenon to understand those experiences better and lay the foundation for future studies (Cresswell & Poth, 2018). The research uses a sample of 27 participants who experienced VR for the first time and answered open-ended questions concerning that experience, in addition to demographic questions. Participants were given 30 minutes each to select from various VR games and YouTube 360 videos in their first-ever encounter with using a VR headset. In-depth field notes were taken during the experience by the researchers, and post-experience interview prompts for participants were based on previous studies on VR immersion and flow theory. This exploratory, phenomenological study provides three themes that emerged from the data: disorientation and immersion, surprise, and a gradual release on reality. Possibilities for future research and the addition of novelty to the technology acceptance model are discussed.","PeriodicalId":39396,"journal":{"name":"International Journal of Information and Communication Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83151489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We live in an epoch when the technological devices we use afford us immense opportunities to form identities in virtual spaces. However, the most critical aspect of Park and Lemish’s book is that it delineates the process of creating hybrid identities—that links identity formation in virtual spaces to that of offline—of an immigrant youth group, namely the Korean American community. Throughout the book, the authors tackle the nuances of adolescent immigrant identity creation, such as the struggle of ethnic identity development, the practice of photo-sharing through smartphones, and bilingualism. By looking at the subject matter through the lens of segmented assimilation theory, this book's findings help make sense of the process by which immigrant children in the United States use digital media technologies, often creatively, to preserve and redefine ethnic identities while dealing with the local assimilative forces. Both authors identify as immigrants, which helps them develop a solid immersive methodology as they interview the Korean American youth who participated in the study.","PeriodicalId":39396,"journal":{"name":"International Journal of Information and Communication Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85103941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
