Book Description
ABSTRACT: Asymmetric communication based on data broadcasting is an appropriate model for Internet and wireless computing. Research problems in such an environment have drawn much attention in the past few years. While many have been addressed, unresolved issues exist and efficient solutions are needed. In this dissertation, we introduce the concept of broadcast-based asymmetric communication. We survey current research in this type of environment, including broadcast scheduling, cache strategies, indexing, concurrency control, fault tolerance, and real-time scheduling. Then we report the research efforts on several topics applicable to the broadcast environment. Compared with the existing research, which mainly considers individual data operations, the purpose of our research is to support efficient multi-operation transaction processing in broadcast-based asymmetric communication environments. The researched topics focus on efficient transaction concurrency control protocols, transaction processing in hierarchical broadcasting models, and performance issues for transaction processing. New algorithms and improvements to existing algorithms are sought in these topics. We also describe the design and implementation of a simulation framework that can be used to evaluate the performance measures of the proposed protocols and environment. The simulation results show very successful performance of our solutions. These results and efficient solutions can contribute to various broadcast-based transaction processing applications.

Book Description
The 9th International Conference on Database Systems for Advanced Applications (DASFAA 2004) was held during March 17-19, 2004 on the beautiful Jeju island of Korea. The DASFAA conference provides an international forum for technical discussions among researchers, developers, and users of database - stems from academia, business, and industry. The main focus of DASFAA is on research in database theory, development of advanced DBMS technologies, and their advanced applications. A premier database conference in the Asia/Pacific region, DASFAA has been held every two years, and in many countries in the region. To promote the area further and to answer the needs of many participants, the steering committee decided to hold the conference annually. DASFAA 2004 was the first such annual conference. The conference was organized by the Special Interest Group on Databases (SIGDB) of the Korea Information Science Society and the Advanced Information Technology Research Center (AITrc) at KAIST - an engineering research center of excellence (ERC) supported by the Korea Science and Engineering Foundation (KOSEF). We had a number of sponsors who made generous contributions to make the conference successful. They are Oracle Korea, Samsung SDS, Korea Telecom Data, Inc., the United States Air Force Office of Scientific Research, the Asian Office of Aerospace Research & Development, the Army Research Office-Far East, and the Korea Advanced Institute of Science and Technology (KAIST).

Book Description
Almost all pathologists face legal issues when dealing with the specimens they work with on a day-to-day basis, whether it involves quality control and assurance in handling the specimens, facing the possibility of malpractice suits, or serving as an expert witness in a trial. Written in an easy to read, conversational tone, with a dose of good humor, this book fills the need for a handbook that discusses the full spectrum of legal issues that many pathologists face, written from a pathologist's point of view. Organized in 12 user-friendly chapters, the book begins with a comparison of Law and Medicine and explains the basics of the American Legal System. It continues with discussions of the impact of law on the practice of pathology, including such topics as specimens with potential legal implications, the controversy of saving organs for teaching, procuring and saving specimens for toxicology testing and DNA confirmation in identity testing. A must-have section on malpractice suits covers reasons why patients sue, what to do if sued, and reducing the chance of being sued. The author addresses expert witness testimony, including how to be an expert witness, conflicts of interest, conduct in a courtroom, what to say and what not to say. Quality control and assurance as it applies to the pathologist is also discussed. Legal implications for the information age, including the use of internet and e-mail with regard to patient confidentiality is discussed in detail. Case samples are scattered throughout the text to illustrate the principles discussed. Every term is defined in the glossary.

Book Description
Motivation Modem enterprises rely on database management systems (DBMS) to collect, store and manage corporate data, which is considered a strategic corporate re source. Recently, with the proliferation of personal computers and departmen tal computing, the trend has been towards the decentralization and distribution of the computing infrastructure, with autonomy and responsibility for data now residing at the departmental and workgroup level of the organization. Users want their data delivered to their desktops, allowing them to incor porate data into their personal databases, spreadsheets, word processing doc uments, and most importantly, into their daily tasks and activities. They want to be able to share their information while retaining control over its access and distribution. There are also pressures from corporate leaders who wish to use information technology as a strategic resource in offering specialized value-added services to customers. Database technology is being used to manage the data associated with corporate processes and activities. Increasingly, the data being managed are not simply formatted tables in relational databases, but all types of ob jects, including unstructured text, images, audio, and video. Thus, the database management providers are being asked to extend the capabilities of DBMS to include object-relational models as well as full object-oriented database man agement systems.
