Abstract This paper discusses the issues and challenges involved in an enterprise-centric approach to the managing of digital content. The writer specifically focuses on the management of medical imagery, a field commonly referred to as digital asset management. Additionally, the writer discusses the need for standards that provide for the creation of digital medical imaging systems.
From the Paper "At the center of integration efforts within the medical digital imaging system design efforts in the industry today is the creation of the virtually integrated electronic patient record (VIEPR), which is the basis of the future generation of wireless and web-based applications that are capable of "tracking" to patients as they progress through treatment programs. The VIEPR concept is aimed at taking digital medical imaging strategies and making them on an "always on" status that patients can present for analysis by medical professionals including radiologists and medical specialists. The future of thin-client based medical digital imaging delivery applications is based on this technology."
Discusses the use of digital imaging in hospital radiology departments, the promise it holds, how it is evolving and the main types of digital imaging.
Abstract This paper explains that, in spite of the usefulness and potential of the digital imaging process in hospital radiology departments, the cost of the equipment it requires has stopped digital imaging in hospital radiology departments from progressing and growing as fast as was hoped. The paper also explains that the slow progression towards digital imagery does not mean that the importance for the future that the technology holds should be discounted. The paper then discusses the two main types of digital imaging systems as they relate to hospital radiology departments and concludes with a discussion of image quality and its significance. A copy of the source documents used are also appended to the paper.

Image Quality
From the Paper "Digital imaging in hospital radiology departments came about for several reasons. The most important of these, however, was the idea that the digital images could be viewed by any authorized person at any time, thus making it much easier and faster for those that needed to see them to have access to these images (Gillespie, 1999). These digital images eliminate the need for films and film libraries, thus freeing up space, as well. However, there are still problems with this issue that have stopped digital imaging in hospital radiology departments from progressing and growing as fast as was hoped. The major concern for these departments is the cost that is incurred when it comes to the digital imaging equipment, which is much more expensive than the older methods that were previously used to take x-rays and perform other functions (Gillespie, 1999)."
Abstract Information Technology communication brings with it the challenges which have beset the human race since their initial attempts to interact upon a social and trading basis. This paper examines the idea that intellectual property throughout the world needs to be harmonised with the protection of a creators rights protected by a more codified international agenda.

Introduction: Why the Harmonisation of Copyright Laws and Systems is Important Especially in the Digital Age
The Main Issues of Current Copyright Protection in the Digital Age The Transformation of International Copyright Through International Treaties
The Obstacles in the Way of a Global Copyright System Conclusion: The Future of International Copyright Laws -Further Harmonisation
From the Paper "Information Technology communication brings with it the challenges which have beset the human race since their initial attempts to interact upon a social and trading basis. As democratic governance involves public debate and open decision-making, the organisation of interests groups, and the free exchange of ideas, opinions and information is essential. To a greater degree than ever, open media provides a critical measure of progress towards democracy. Access to information and the right to freedom of expression are central elements in ensuring the voice and participation necessary for the development of a democratic, civil society."

Abstract This paper defines digital radiography as a branch of radiography which converts X-ray images to electronic data which can then be viewed and read by radiologists on a monitor. The writer stresses the convenience of being able to store digital radiographic images on computer discs. This paper details the various uses and advantages of digital radiography including the fact that this particular method is quicker and far more accurate than the previous practice of producing x-ray images. This paper discusses the differences between computed radiography and digital direct radiography while also delving into the pros and cons of both radiographic methods.
From the Paper "The 'Direct Digital Radiography' System provides options for the transition to digital technology. This system offers the highest quality images that are available in DR today. Developed only in recent years, the system can be used across a large number of potential applications. The advantages of the system are that it consists of two types of detectors, one direct and the other, indirect. In the setup for its imaging, indirect sensors convert x-rays into light, and then convert that into electronic signals. The images depend on both signal profiles as well as on image resolution. The system relies on a scintillation method, wherein x-ray energy may be converted into light, and this light can then be converted into electronic signals by thin-film diodes."

Abstract The paper refers to critical media sources and some laws regarding the threat posed by digitalization to corporate recording interests. The paper provides a commentary on the overall phenomenon of digitalization as it stands to alter consciousness and what we understand by copyright, by laws involving special ownership and the very nature of reality. The paper notes the failure to distinguish between digitalization and its more cultural, thematic result in the digitalization that is such a threat to recording industry sovereignty.
From the Paper "Digitalization presents a number of considerations that affect the whole business of media and communication, as they have generated corporate wealth for a half-century or so. Moreover, digitalization may indicate a permanent shift in how cultural products are understood, our consciousness of what is accessible and our sense of entitlement, property and laws governing these concepts. Corporations are losing control of recorded products over which they once enjoyed monopoly and forcing new ventures of unknown success. Indeed, interests whose products are threatened by digitalization are proving to be poor sports, wanting capitalist activities protected by public and legal intervention."
Abstract The topic of this study is the digitization of photography and its impact on arts institution administration. The writer discusses that there are several avenues to be explored when assessing the impact of digitization, from the purely technical to the purely artistic. Within the exploration of these areas of interest, the writer maintains that an assessment may be constructed regarding what changes, for good or ill, might be caused by an increasingly expanding digital photography universe and not least because of the sudden and almost total accessibility of virtually everyone to digital photography equipment. The writer claims that this will undoubtedly change the photography world; whether it will cause a greater or lesser interest in the work of photographic artists has yet to be seen. The writer concludes that in either case, however, the process is likely to cause significant change in art administration.

Justification
From the Paper "Because photographic digitization depends on developments in information technology, an assessment of Moore's Law on the changes in photography and resulting changes in arts administration is required. Moore's Law, developed by Gordon Moore a generation ago, when computing was in its relative infancy, proposes that "the performance for a given price of microprocessors doubles every 18 months...." At the time, Herman said that process continued unabated; it is conceivable that the doubling of capacity is even quicker by now.
In any case, because of this, planning for 'cutting edge' shows would become more and more demanding; in fact, it will become more and more incumbent upon arts administrators to keep breast of changes in digital photography, and perhaps even to anticipate them. This changes the administration role from a relatively passive to quite an active role."

Conclusion
From the Paper "To be able to understand the electronic systems in use today, it is important to look into the early history of electronic banking. All of the systems in use now have their foundations in the early systems that were developed thirty years ago. It is interesting to note that the history of early electronic banking parallels the time frame of Internet development. The Internet has always been an integral part of electronic banking and will continue to play a vital part in the electronic world of the 21st century."

Abstract This paper explores the various aspects of digital painting enhancement from ethical concerns to techniques. The paper looks at how digital enhancement allows the artist to go beyond the limitations of the brush, bringing a new dimension to art. The paper contends digital enhancement should be considered as just another tool for the artist to use.
From the Paper "Every time technology moves ahead, invading the world of art, we are presented with exciting new opportunities along with difficult challenges. Such is the case with the advent of digitally enhanced painting. Digital enhancement allows us to push the envelope, invent new forms of expression, add rich dimension to old forms and step into the refreshing world of the unexplored. Although digital enhancement is resisted by some people for what are probably excellent reasons, it is embraced by others for reasons just as laudable..."
Abstract In this article, the writer discusses how the act of business transactions have changed due to the progress in technology. The writer examines the effect of digital signatures on e-commerce, including the need for digital signatures. In this paper, the writer explores how digital signatures work. The paper also discusses the outlook for the future. Further, the writer looks at the importance of identity in cyberspace.
From the Paper "For thousands of years transactions between individuals were conducted face-to-face. There was little doubt about who the buyer or seller was and when cash was involved it was not necessary to know for certain who was whom. Indeed even in today's high-technology world, cash transactions still carry the greatest amount of anonymity since the funds are guaranteed. As credit became more and more common, it became necessary to ensure that the persons involved with commercial transactions had the authority to perform those transactions."

Abstract This paper explains how scanners can transfer text and pictures into digital form for manipulation and storage. The author points out that digital imagining allows storage in a smaller area. The paper relates that digital imagining manipulates information into a different format for use in desktop publishing of company documents and similar uses.
From the Paper "Digital imaging has a wide variety of uses today, serving as a new means of photography, empowering office copiers, allowing for the transfer of images over long distances, and so on. Digital technology is computer technology translating information into a series of numbers, computer code that can be read and transformed back into the original form. Digital information can be text, sound, or pictures when translated, and in its digital form the information can be stored, retrieved, sent from one place to another, and altered, all with greater ease than changing the original material. Digital imaging in the workplace is found in office computers, copiers, fax machines, databases, and so on."
Abstract The Internet has clearly changed the playing field for a wide range of enterprises in the past decade, but one of the fundamental changes that is taking place and that may be going unnoticed by the general public, is the use of the Internet to facilitate telephonic communications. While the majority of advocates of such systems recognize that the benefits to be realized are associated with cost savings rather than improvements in functioning over existing PBX-based systems, the trend is clear that Internet-based telephony is here to stay and will be improved in the years to come. This paper provides the background and an overview of the issues involved, followed by an analysis of PBX versus voice over IP telephone systems. A summary of the research is provided in the conclusion.
From the Paper "The benefits of Internet-based telephone systems will likely relate to lower costs rather than improved or enhanced functions. Clearly, the Internet is a natural network for these applications more so than the existing telephone system for a variety of reasons. For instance, packet switching allows these applications to be mixed with others over a common network, and voice can be combined with other modes of communication such as text, video, shared workspace, and so forth. For telephone-like applications, the Internet can deliver the signaling information all the way to the end node, so the telephone features can be implemented at the edge of the network."

Abstract This essay discusses how the economics of digital goods have now cast doubt on traditional models of markets and government intervention. This is especially the case in the context of the notion of privacy. Many people still demand privacy in this culture and see it as their right. But privacy expectations have had to change in terms of the digital revolution.
Abstract This paper discusses the advantages and disadvantages of analog vs. digital recording formats from the standpoint of listening, accessing and storing music. The author evaluates the sound quality of each format. The paper concludes that digital is a better all-around format.
From the Paper "Before digital-format music CDs came out in the seventies, music was often recorded in analog format on phonograph records or tape cassettes. Analog and digital solutions work quite differently though and yield different results even when they ..."
Abstract The paper addresses the gender gap within the digital divide between men and women, and across nations and economic levels. It gives reasons why the gender gap is a cause for concern, and why the digital divide is important.
From the Paper "Men and women do not access information and communication technology ICT at the same rates nor do they enter the fields that develop future ICT applications and direction at the same rates. There is a digital divide that is widening between men and women in this regard and the divide exists across nations and economic levels. This research considers the digital divide in general, the gender gap within the digital divide in particular and reasons that the gender gap ..."

Abstract The writer looks at how the concept of a camera and film has evolved and been transformed over the years. In this paper, the writer examines the workings of a digital camera. The article includes relevant illustrations. The writer also considers the benefits of digital cameras over film cameras.
From the Paper "Cameras of all kinds-still video film digital-have become so ubiquitous that Americans seemingly take them for granted. Once cumbersome to the point that taking a photograph required subjects to sit still for several minutes, today's cameras have progressed to the point that they exist in cellular phones. Despite the fact that digital and film cameras are both called cameras they use significantly different technology to capture images. This research considers how film cameras evolved into digital cameras and the advantages associated with the ... "
