There has been an explosion in the development of electronic methods for psychological assessment. These include use of handheld devices, desktop computers, and platform-based Internet methods. This development has occurred separately in the commercial environment and in the research environment. This development of new methods presents great promise to improve the accuracy, ecological validity, and range of constructs in psychological assessment. However there are also many problems involved in the development of these electronic methods, including the need to train clinicians in their use, the need to develop safeguards for privacy, and the need to develop methods to ensure the integrity of the data collected. This chapter outlines some of the main considerations in moving forward.

Drug Eluting

The development of new methods for drug elution of graft material, biofiber films and resurfacing of prosthetic graft surfaces offers new opportunities for improvement of graft function in arteriovenous (AV) access. Three areas of research include developing grafts that reduce the development of neointimal hyperplasia, reducing infection and reducing thrombogenicity. The only drug eluting graft presently being used, is the heparin coated expanded polytetrafluoroethylene (ePTFE) graft, which has been shown to decrease the incidence of early thrombosis. New drug eluting grafts include those with paclitaxel and those with antibiotics. The development of a hybrid coated prosthetic graft that can deliver targeted gene therapies holds great promise in the field.

The psychological assessment of children and youth has undergone some of the greatest developments, and those developments are the focus of this Handbook. The volume is organized primarily, but not exclusively, around clinical and psychoeducational assessment issues. It revisits the foundations that underlie current psychological assessment practices. Linked with these foundations are chapters addressing some of the fundamental principles of child assessment that focus on ability, achievement, behavior, and personality. Theory offers guidance in practice when techniques change, new methods are introduced, and new data are presented, as well as when psychologists encounter new presenting issues and circumstances with patients, or when asked new questions by referral sources; some specific examples are provided in the fourth section of this volume. The book hopes to see theory integrated with research and practice to enable readers to view the articles in this book, as well as future publications, not just more profitably but critically as well.

Swimming is one of the most popular spots among college students, though it is hard to master. With virtual reality (VR) technology, problems of the low-cross mutual inductance and low efficiency can be solved. A physical model and the software framework of the virtual reality system was proposed. The swimming teaching system can solve the problem that perception-action separation, improve the study ecological validity, and hold great promise for the study of perception- action. A comparison analysis between students' correct and wrong swimming movements is carried out, and the analysis results show that the virtual reality system solves the problem of monotonicity in real swimming teaching.

Background: The computer has become increasingly intertwined in society for the past 30 years. Within the academic health science centre, there is an increasing need for researchers to become skilled at using the Internet as a mechanism for the retrieval of scientific results and the underlying data. The discipline of bioinformatics, which uses computer technology to provide answers to biological questions, has been expanding in scope and utility for the past decade. Increasing numbers of research groups have been investing in bioinformatics infrastructure to aid in the research process. These continuing investments have led to the establishment for the first time of a supercomputing facility within a hospital. Such computational power is being used for the mapping of genes and the study of human disease. Objective: A discussion of the increasing role of computational biology in the research environment of the clinician scientist is presented here. Conclusions: Though the investment in a supercomputer may not be possible in most research settings, several less expensive alternatives relying on existing desktop computers can provide supercomputer-like performance within nearly any environment.

Information navigation on handheld displays is characterized by the small display dimensions and limited input capabilities of today’s mobile devices. Special strategies are required to help users navigate to off-screen content and develop awareness of spatial layouts despite the small display. Yet, handheld devices offer interaction possibilities that desktop computers do not. Handheld devices can easily be moved in space and used as a movable window into a large virtual workspace. We investigate different information navigation methods for small-scale handheld displays using a range of sensor technologies for spatial tracking. We compare user performance in an abstract map navigation task and discuss the tradeoffs of the different sensor and visualization techniques.

Further Development

A variety of structured assessment tools for use in surgical training have been reported, but extant assessment tools often employ paper-based rating forms. Digital assessment forms for evaluating surgical skills could potentially offer advantages over paper-based forms, especially in complex assessment situations. In this paper, we report on the development of cross-platform digital assessment forms for use with multiple raters in order to facilitate the automatic processing of surgical skills assessments that include structured ratings. The FileMaker 13 platform was used to create a database containing the digital assessment forms, because this software has cross-platform functionality on both desktop computers and handheld devices. The database is hosted online, and the rating forms can therefore also be accessed through most modern web browsers. Cross-platform digital assessment forms were developed for the rating of surgical skills. The database platform used in this study was reasonably priced, intuitive for the user, and flexible. The forms have been provided online as free downloads that may serve as the basis for further development or as inspiration for future efforts. In conclusion, digital assessment forms can be used for the structured rating of surgical skills and have the potential to be especially useful in complex assessment situations with multiple raters, repeated assessments in various times and locations, and situations requiring substantial subsequent data processing or complex score calculations.

Wide Range

Nanomedicine is currently showing great promise for new methods of diagnosing and treating many diseases, particularly in kidney disease and transplantation. The unique properties of nanoparticles arise from the diversity of size effects, used to design targeted nanoparticles for specific cells or tissues, taking renal clearance and tubular secretion mechanisms into account. The design of surface particles on nanoparticles offers a wide range of possibilities, among which antibodies play an important role. Nanoparticles find applications in encapsulated drug delivery systems containing immunosuppressants and other drugs, in imaging, gene therapies and many other branches of medicine. They have the potential to revolutionize kidney transplantation by reducing and preventing ischemia–reperfusion injury, more efficiently delivering drugs to the graft site while avoiding systemic effects, accurately localizing and visualising the diseased site and enabling continuous monitoring of graft function. So far, there are known nanoparticles with no toxic effects on human tissue, although further studies are still needed to confirm their safety.

Handheld devices are increasingly capable of running applications that used to require laptop and desktop computers. The requirement that these devices provide better performance with a smaller form factor or size presents significant challenges, especially with the limitations of passive cooling. The current study presents a summary of the cooling solutions of several popular, commercially available tablets. The trends in power dissipation and thermal management techniques of handheld devices are presented. The factors affecting the maximum possible power dissipation are discussed. The effects of the selection of the outer shell materials, the thermal interface materials, heat spreaders and air gaps are presented. For all considered thermal management techniques of handheld devices, a figure of merit for the cooling solutions is defined as: Figure of Merit = Maximum Power Dissipation / Surface Temperature Rise, in (W/degC). This figure of merit allows for an objective comparison of the available cooling solutions.

This chapter reports on a case study linking several technology devices that monitor a range of vital signs in patients recently discharged to a hospital ward from the Intensive Care Unit (ICU). Apart from presenting an interesting technological challenge, this closed environment creates unique logistical and physical ergonomic challenges as well as cognitive and perceptual design problems for mobile technology. Devices include desktop computers, touch monitors, and several types of remote mobile devices including PDAs. A number of important design issues are addressed, such as deciding which visual details can be safely eliminated from a small display, or if permission should be given to turn off the alarm functions, among others. Lack of direct access to users compromised the ecological validity of several parts of the evaluation and alternative evaluation methods had to be devised.
