How digital data are used in the domain of health: A short review of current knowledge

In the era of digitalization, digital data is available about every aspect of our daily lives, including our physical and mental health. Digital data has been applied in the domain of healthcare for the detection of an outbreak of infectious diseases, clinical decision support, personalized care, and genomics. This paper will serve as a review of the rapidly evolving field of digital health. More specifically, we will discuss (1) big data and physical health, (2) big data and mental health, (3) digital contact tracing during the COVID-19 pandemic, and finally, (4) ethical issues with using digital data for health-related purposes. With this review, we aim to stimulate a public debate on the appropriate usage of digital data in the health sector

Narrative motion on the two-dimensional plane: the “video-ization” of photography and characterization of reality

"Art is not truth. Art is a lie that enables us to recognize truth" Pablo Picasso Time, as known to many, is an indispensable component of photography. Period(s) included in “single” photographs are usually and naturally much shorter than periods documented in video works. Yet, when it comes to combining photos taken at different times on one photographical surface, it becomes possible to see remnants of longer periods of time. Whatever method you use, the many traces left by different moments, lead to the positive notion of timelessness (lack of time dependence) due to the plural presences of time at once. This concept of timelessness sometimes carries the content of the photo to anonymity, the substance becomes multi-layered and hierarchy disappears. This paper focuses on creating photographical narratives within the two-dimensional world. The possibility of working in layers with transparency within the computer environment enables us to overlay succession of moments seized from time on top of each other, in order to create a storyline spread in time that is otherwise not possible to express in a single photograph, unless properly staged. Truth with the capital T is not taken as the departure point in this article; on the contrary, personal delineations of temporary yet experienced smaller realities is suggested

Library websites popularity: does Facebook really matter?

The purpose of this paper is to determine whether the utilization of social media (Facebook) is an important factor in increasing the visibility of the library site usage in Malaysian public universities. Nine top ranked Malaysian public universities involved in this research and number of Facebook followers for each library website is listed. Alexa software was used as the approach to study the issue of visibility. Alexa is able to determine web site usage, by showing the percentage of visitors of library related subdomain(s) as listed in the top subdomains for each University website (domain) over a month. It is found that Universiti Utara Malaysia library website scored the highest percentage of visitors based on the library related subdomain(s) as listed in the top subdomains for the University website in Alexa. To check such irregularities in access, this paper use EvalAccess 2.0 and it is found that Universiti Sains Malaysia’s library website scored higher irregularities. In term of number of Facebook followers, Univesity of Malaya library has the highest score. It is showed that the utilization of social media (Facebook) is not yet an important factor in increasing the visibility of the library websites. However, expectedly, top ranked universities’ library web sites, are more visible and popular. This research is limited to the situation in Malaysia where public universities are more noticeable and seldom face financial constraints rather than private universities. It is highly important for those universities’ library web sites that are not highly visible to initiate the necessary measures in improving the development of their web sites as the usage of the website is an indicator of online quality

Recent Development of Hybrid Renewable Energy Systems

Abstract: The use of renewable energies continues to increase. However, the energy obtained from renewable resources is variable over time. The amount of energy produced from the renewable energy sources (RES) over time depends on the meteorological conditions of the region chosen, the season, the relief, etc. So, variable power and nonguaranteed energy produced by renewable sources implies intermittence of the grid. The key lies in supply sources integrated to a hybrid system (HS)
