An overview in healthcare information systems security.

The scope of this paper is to present the current needs and trends in the field of healthcare systems security. The approach applied within the described review was based on three major steps. The first step was to define the point and ways of penetration and integration of security services in current healthcare related applications addressing technical, organisational and legal/regulatory issues. The second step was to specify and evaluate common security technologies applied in healthcare information systems pointing out gaps and efficient solutions, whereas the third was to draw conclusions for the present conditions and identify the future trends of healthcare information security. A number of EU RTD Projects were selected, categorised, analysed and comparatively evaluated in terms of security. The technical focus was on key security technologies, like Public Key Infrastructures (PKIs) based on Trusted Third Parties (TTPs) in conjunction with other state-of-the-art security components (programming tools, data representation formats, security standards and protocols, security policies and risk assessment techniques). The experience gained within this review will provide valuable input for future security applications in the healthcare sector, solving existing problems and addressing real user needs.

[Training before departure of volunteers during nutritional emergencies. From inception to evaluation].

Predeparture training is rarely undertaken within emergency nongovernmental organizations. Although field-training is considered as the only real school, the technical requirements are increasingly more constraining. To cope with this problem, the technical officers of Action contre la faim planned a predeparture training project based on self-instruction of any volunteer leaving for a nutritional emergency mission. The project began in 1994. Six self-instruction sessions were produced to enable volunteers to learn. To improve the quality of work, this framework encouraged creativity, constant research and motivation. The training supervisor accompanied the volunteers and put them in simulated situations where various tools were made available to them. A series of measures have been used to improve this basic training: 1) a training contract meant to make the volunteer responsible for his training; 2) better programming to ensure adequate relay from one volunteer to the next; 3) an apprentice report covering the first 15 days of the volunteer's integration into the field, thereby providing important feed-back to the supervisor; 4) an evaluation of the monthly report and an interview-grid used to follow the volunteer in the short and medium-term; 5) and an evaluation form completed by the volunteer which enables the updating of sessions and simulated situations. This initiative has made us aware of the importance of following the volunteers at all stages: this can increase the volunteer's efficiency and their fidelity to the non-governmental organization. Currently, the main objective is to gain the support of qualified technical coordinators who will be the most important factor in continuous training.

Early establishment of adult-like nigrotectal architecture in the neonatal cat: a double-labeling study using carbocyanine dyes.

Virtually nothing is known about the ontogeny of substantia nigra, pars reticulata projections to the midbrain superior colliculus, even though this pathway is critical for the basal ganglia modulation of midbrain-mediated visuomotor behaviors. The present studies used the lipophilic carbocyanine dyes 1,1'-dioctodecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate and 1,1'-dioctodecyl-3,3,3',3'-tetramethylindodi, 4-chlorobenzenesulfonate salt to examine the crossed and uncrossed nigrotectal projections in neonatal cats, from parturition to 14 days postnatal (the technical limits of the tracing technique). In retrograde experiments, paired placement of the dyes in each superior colliculus produced numerous retrogradely-labeled nigrotectal neurons, with the uncrossed neurons far out numbering their crossed counterparts. No double-labeled neurons were observed, indicating that crossed and uncrossed nigrotectal neurons are segregated at birth. In anterograde experiments, dye placements into each substantia nigra, pars reticulata resulted in an iterative series of labeled patches, aligned medial-to-lateral across the intermediate and deep superior colliculus, a pattern reminiscent of the adult. Uncrossed neonatal axons had simple linear morphologies with few branch points; by contrast, crossed axons displayed more extensive terminal arbors that were distributed diffusely throughout the rostrocaudal extent of the contralateral superior colliculus In the final series of experiments, one dye was placed unilaterally in the substantia nigra, pars reticulata, while the second dye was positioned in the predorsal bundle, in order to bilaterally label superior colliculus output neurons. Although both crossed and uncrossed axons appeared to have contacted superior colliculus output neurons, crossed axons preferentially targeted the soma and proximal dendrites, whereas uncrossed terminals were distributed more distally. Throughout this early postnatal period, no significant changes in cellular morphologies or gross modification of terminal projection patterns were observed; however, the presence of growth cones in even the oldest animals studied suggests that the refinement of the nigrotectal projections extends well into postnatal life. Nevertheless, the segregation of crossed and uncrossed nigrotectal neurons into a highly organized afferent mosaic that has established synaptic contacts with superior colliculus output neurons indicates that many of the salient features characterizing nigrotectal projections are established prior to the onset of visual experience.

Integrating ergonomics and engineering in the technical design process.

Leyland DAF and the University of Nottingham collaborated in establishing an ergonomics team to support the truck design and development process in the company. The project was planned within the framework of a Teaching Company Scheme funded jointly by Leyland DAF and the UK government. This framework provided a training environment in which the team, which was formed of young professional ergonomists and engineers, could quickly acquire the specialist skills needed for work in the automotive industry in addition to gaining practical experience in applying ergonomics, and the programme was structured to promote the integration of ergonomics and engineering considerations within the technical design process. The experience gained in this project has shown the benefits of such an approach to implementing ergonomics in product design, and provided an insight into the ways in which ergonomists and designers can communicate more effectively in a manufacturing organization.

[Study of interneuronal connections by the technic of luminescent demonstration of retrograde transport of primulin].

A possibility to study associative and projective connections of the optic cortical fields by the method of luminescent revealing of primuline retrograde transport has been demonstrated in the experiments with cats. Initial neurons of the connective systems have been revealed in various fields of the optic cortex (fields 17, 18, 19) and in the lateral geniculate body of the thalamus. The initial cells have various luminescent intensity.

Telemedicine information analysis center.

Congress mandated a pilot project to demonstrate the feasibility of establishing a Department of Defense (DoD) telemedicine information analysis center (TIAC). The project developed a medical information support system to show the core capabilities of a TIAC. The productivity and effectiveness of telemedicine researchers and clinical practitioners can be enhanced by the existence of an information analysis center (IACs) devoted to the collection, analysis, synthesis, and dissemination of worldwide scientific and technical information related to the field of telemedicine. The work conducted under the TIAC pilot project establishes the basic IAC functions and assesses the utility of the TIAC to the military medical departments. The pilot project capabilities are Web-based and include: (1) applying the science of classification (taxonomy) to telemedicine to identify key words; (2) creating a relational database of this taxonomy to a bibliographic database using these key words; (3) developing and disseminating information via a public TIAC Web site; (4) performing a specific baseline technical area task for the U.S. Army Medical Command; and (5) providing analyses by subject matter experts.

[Development features of regional population aging in Finland].

"Population ageing has emerged as one of the crucial problems facing developed countries. In Finland, the old population (aged 65 and over) has doubled in numbers over the past 30 years. The phenomena underlying this ageing trend include a decline in fertility, increase of the average life expectancy, and the effects of migration. Considerable regional differences in population ageing can be observed between Finland's provinces, municipalities and between their different parts. The number of the elderly is projected to increase in all provinces, the highest relative increase taking place in the provinces of Lapland, Uusimaa and Oulu between 1990-2020." (SUMMARY IN ENG)

Cooperation in health affairs between adjacent international communities: a successful model.

The border between the United States and Mexico presents a number of problems related to health that are simultaneously local and international. Large-scale government-to-government interactions have generally failed to achieve lasting cooperation on important health issues, with a few important exceptions. One reason for this may be that the issues have been complicated by much larger and more complex social, cultural, economic, and political differences. Another is that large organizations must each function according to their own mandates, goals, and procedures and may not mesh well with others, even with nominal counterparts. In 1981 we conceptualized a model for encouraging binational cooperation on small-scale local projects. The model incorporates three elements: a significant and difficult but soluble technical problem affecting both sides of the border (the "technocratic factor"), a mutually respected individual or team whose function is to facilitate communication and prevent misunderstandings (the "human factor"), and the actions of governments or institutions larger than the working groups (the "institutional factor"). Subsequently, we applied the model to water quality and to the distribution of sources of toxic substances in the border area, which met the criteria for the technocratic factor. Two highly respected figures in environmental health, one American and one Mexican, mediated between colleagues on either side of the border and facilitated the development of projects. Finally, after the projects had been under way long enough to have demonstrated their viability and personal interactions among the principals had become trusting and collegial, the institutional factor was admitted and major financial and administrative support obtained.(ABSTRACT TRUNCATED AT 250 WORDS)

A noninvasive thermoplastic head immobilization system. Technical note.

The authors have developed a noninvasive head immobilization system for use in neuroimaging (magnetic resonance imaging, computerized tomography, single photon emission computerized tomography, and projection angiography), neurosurgical planning, and neurosurgery. These diagnostic and surgical procedures require patient immobilization, reproducible patient positioning, and anatomical localization. The thermoplastic system described in this technical note addresses each of these requirements with a high degree of accuracy and with no bone fixation. The reproducibility of positioning and effectiveness of immobilization were evaluated using nine healthy volunteers during repeated sessions of magnetic resonance imaging. The mean axial displacement for repeated positioning was 0.6 mm (variance 0.1 mm); the mean displacement during robust patient motion in the axial direction was 1.8 mm (variance 0.9 mm).

A cheap technical solution for cranioplasty treatments.

Skull defects are treated by cranioplasty techniques, which are required to protect underlying brain, correct major aesthetic deformities, or both. This research is a part of our research project in ASEAN countries to investigate (i) the methods for design and manufacturing of cranioplasty implants, and (ii) the feasible technical solutions of minimizing the implant cost based on available production and biomaterial technologies in the region. In this paper, solutions for design and manufacturing of standardized implant templates (SDT) are presented. SDT are made based on the reverse engineering and rapid tooling techniques. With the use of SDT, surgeons have flexible options in preparing the implant both pre and intra operatively, and the operation time is minimized. In addition, the skills required to prepare an implant from SDT are not highly required. The cost for cranioplasty treatments by using SDT is acceptable for ASEAN region.
