Abstract

Background

Biomedical three-dimensional images sets are becoming ubiquitous, and the atlas canonical providing the framework for spatial analysis. To take full advantage of this 3D image sets, we must be able to present the views 2D display, or the surface of records or 2D cross-sections through the data. Typical of the software is limited to presentations on one of the three orthogonal axes anatomical (coronal, sagittal or horizontal). However, the data sets specifically oriented along the major roads are rare. To make full use of these data, one must reasonably reflect the atlas guidance, which implies resampling in the atlas planes compared with the data set. Traditionally, this requires the atlas and the browser are on the user's desktop, unfortunately, in addition to being monolithic programs, these tools often require substantial resources. In this article, we describe a network capable, and client part of the deal and 3D visualization atlases at off-axis angles, with a score of architecture and development kit to facilitate their integration in complex environments data analysis.

Results

Here, we describe the basic architecture of a client / server 3D visualization system, consisting of a thin client built on a Java Development Kit, and a calculation robust, high-performance server written in ANSI C + +. The client Java components (NetOStat) support arbitrary viewing angle and manage readily available on desktop computers running Mac OS X, Windows XP or Linux in a downloadable Java Application. Using the NeuroTerrain Software Development Kit (SDK NT), Atlas of sophisticated navigation can be added to any application compatible Java requiring as little as 50 lines of Java code glue, which makes it eminently re-useable and more accessible to programmers build more complex, the tools for analyzing biomedical data. The NT-SDK separates interactive GUI components from the server control and monitoring, in order to support the development of non-interactive applications. The application server takes full advantage of the data center of high performance equipment, which can be located together with centrally-located, 3D data repositories, expanding access to the research community through the Internet.

Conclusion

The combination of a server optimized and modular platform independent client offers an ideal environment for 3D visualization complex biomedical data, taking full advantage of high-performance servers to prepare imagery and subsets of metadata for display, as well as the graphical capabilities in Java to actually display the data.

Abstract

Background

Indonesia's recent economic and political history has left a legacy of widespread poverty and serious health problems, and has contributed to marked inequalities in health care. One means of responding to these challenges has been through a reconsideration of the professional roles of nurses, to enable them to deal with the range and complexity of health problems. However, there are currently a number of obstacles to achieving these aims: there is a serious shortfall in trained nurses; the majority of nurses have only limited education and preparation for the role; and there is no central registration of nurses, which means that it is impossible to regulate either the profession or the standards of care. This study aimed to establish the occupational profiles of each grade of nurse, identify their training and development needs and ascertain whether any differences existed between nurses working in different regions or within hospital or community settings.

Methods

An established and psychometrically valid questionnaire was administered to 524 nurses, covering three grades and coming from five provinces.

Results

Significant differences in job profile were found in nurses from different provinces, suggesting that the nature of the role is determined to some degree by the geographical location of practice. The roles of hospital and community nurses, and the different grades of nurse, were fairly similar. All nurses reported significant training needs for all 40 tasks, although these did not vary greatly between grade of nurse. The training needs of nurses from each of the provinces were quite distinct, while those of hospital nurses were greater than those of community nurses.

Conclusion

The results suggest that the role of the nurse is not as diverse as might be expected, given the different levels of preparation and training and the diversity of their work environments. This may reflect the lack of a central registration system and quality framework, which would normally regulate clinical activities according to qualifications. The differences in training needs between subsections of the sample highlight the importance of identifying skills deficits and using this information to develop customized post-registration education programmes. Together, these results provide a rigorous and reliable approach to defining the occupational roles and continuing education needs of Indonesian nurses.
