[Study on intelligent system of hyper-spectral data gathering based on GPS in farm machinery].
In order to meet the precision agriculture needs that highly dense and overall farmland information is gathered, this system uses Visual Basic and Map-Objects to carry on integration of GPS, GIS and RS. On the one hand, the system can provide the space seat attribute of high precision for the spectral data gathered by way of integration GPS, and realizes integration in spectrum data gathering, orientation and storage. On the other hand, by way of integrated GIS, the system has realized the function of visualizing analysis and management of the spectrum data, displaying real-time trace of moving point, providing some related attribute of the moving point in map layers, and calculating crop derivative spectra and crop vegetation index NDVI etc. The sufficient information is put forward for expert system and decision support system of precision agriculture.

An analysis of the community periodontal index of treatment needs. Studies on adults in France. V. Presentation of CPITN data in cross-tabulations.
A total of 1005 subjects were examined using the CPITN and DFT indices. CPITN data were modified in their presentation in order to be suitable for cross-tabulation. Two different methods were considered. One, described previously by Roland et al. (1984), classified subjects according to the combination of their highest CPITN score and the mean of the highest scores of every nonedentulous sextant. The other consisted of multiplying the above mentioned mean by the individual's highest CPITN score. A critical analysis of the methodology showed that the two number system developed by Roland et al. (1984) was impractical. The new method provides a linear array of values from 0 to 16. Very little overlapping of values was observed, which means that a relatively precise periodontal condition is characterised by each value. With this transformation the CPITN can be used as an index that quantifies periodontal conditions instead of treatment needs.

Translating mainframe computer data to spreadsheet format.
The translation of mainframe-stored information in ASCII into spreadsheet format for use in Lotus 1-2-3 is explained. Details are presented on how to use the Data Parse command to create a translation template that tells Lotus 1-2-3 how to interpret a file written in ASCII. Lotus 1-2-3 can also translate some files in formats other than ASCII. It can translate files in the Data Interchange Format directly into its own format. Translating mainframe computer data into spreadsheet format is relatively simple and obviates the rekeying of those data.

Graphical non-linear representation of multi-dimensional laboratory measurements in their clinical context.
A polygon-based graphical representation of laboratory test results using nonlinear scaling is described. It is argued that the nonlinearity of the scale and the use of colors in the representation facilitates interpretation of the test result in its relationship to the standard reference range and critical clinical decision levels. Preliminary results suggest that this representation may be fruitfully used to enhance the efficiency of the information transfer from the clinical chemistry laboratory to clinicians. Other applications, inside as well as outside the medical field, may easily be imagined.

Is a picture worth a thousand medical words? A randomized trial of reporting formats for medical research data.
Monitoring data that vary over time is an essential component of medical practice. This is doubly true in clinical trials in which the overall safety and efficacy of investigational treatments in populations must be monitored in addition to the status of the individual patients who receive them. We report the results of a randomized trial of four reporting methods for time-dependent information derived from clinical trials; narrative text, table, pie chart and icon. Multivariate analysis of variance with a repeated measures design was used to analyze the efficiency of subjects' (physicians, research nurses and laboratory personnel) assimilation of information. Icons were found to be superior to the other reporting formats tested in both speed (p less than 0.0001) and accuracy (p = 0.02). The differences were most pronounced in subjects' first exposure to the data, suggesting that icons reduce the time needed for training. We conclude that icons are a valuable method for presentation of time-dependent information in medical settings.

[Three dimensional display of the brain surface from magnetic resonance images using a personal computer].
A new system for three dimensional display of brain surface from magnetic resonance images has been developed using a personal computer. The system consists of the personal computer with a co-processor for mathematical operation and frame memory for full color graphic display. MRI data were transferred to the computer with the floppy disks. Using the paint algorithm, extraction of brain tissue was performed semi-automatically with a manual operation. Brain surface data were displayed on a CRT by a voxel method from an arbitral direction. The result of clinical application of the system showed that the 3-dimensional display of brain surface was useful in comprehending abnormalities including atrophy and cystic lesions. In this paper, we introduce the new system and discuss clinical applicabilities.

[Xenogeneic hyperacute rejection of the lung in rats].
Xenotransplantation, with organs harvested from appropriate donor animals could be a potential solution to the shortage of donor organs in general and of lung grafts in particular. Unilateral orthotopic lung transplantation in the rat has been used to study the lung xenograft rejection in a discordant donor-recipient combination, i.e. guinea-pig to rat. With this microsurgical technique, a high post-operative survival rate has been reached. The good function of the grafts was assessed by serial chest x-ray, lung perfusion scintigraphy until several months after the transplantation. The survival of the xenografts has been then compared to that of allografts and isografts. Lung xenograft rejection in this combination has been very fast: 53 minutes. Macroscopic and histologic data displayed lung infarct with hemorrhagic edema.

[4 cases of Guillain-Barré syndrome with axonal lesions].
We report the neurological features observed in 4 patients who developed a clinically typical Guillain-Barré syndrome. Electrophysiological and histological data displayed an unusual number of axonal lesions, although these were always associated with demyelination. These cases must be distinguished from the rare cases of Guillain-Barré syndrome with pure axonal lesions. Three patients had a poor functional recovery. This confirms the more severe prognosis of Guillain-Barré syndrome with major axonal degenerative changes.

[Strategies of data reduction in computer-assisted EEG analysis in the time domain--measurement of theoretical aspects and redundancy relations within and between various strategies of data reduction].
The enormous amount of data after performing computer assisted EEG-analysis makes necessary reduction methods. Different strategies have been proposed. Traditionally the distribution of frequencies is shown by using frequency bands. The aim of this paper is to compare different strategies of data reduction regarding frequency distribution and to discuss results concerning validity. Three data reduction methods and their mutual relations will be discussed. The classification with regard to frequency bands, the computation of quartils of the frequency spectrum and the search for prominent frequencies. It will be shown wether or not calculated values are redundant and reflect identical information (latent dimensions).

Some methodological issues in statistical estimation of air pollution and health.
This paper introduces a new method for estimating a dose-response relationship from spatially averaged time series of air pollution and health data. Because time is perceived as a nuisance parameter to be eliminated, least-squares regression and traditional time series methodology (e.g., spectral analysis Box-Jenkins methods) are rejected in favor of a nonparametric estimation procedure based on observing health effects in times of nearly equal pollution. The method requires estimating the ratio of two density functions and avoids problems of aggregation, linearity and normality. In spite of the formal tests described, the procedure seems most useful at present as a data analytic and data display device rather than as an inferential tool.

[Ambulatory medical practice in the French-speaking region of Switzerland (1981-1987). Preliminary results].
Between 1981 and 1987, population in the two "cantons" of Vaud and Fribourg increased by 4.5 percent (from 709200 to 740700) but private medical practitioners increased by 26.1 percent (from 971 to 1,224). How did the medical profession adjust itself to such a challenge? The average weekly number of visits reduced (e.g. from 118 to 109 in paediatrics, from 96 to 85 in internal medicine...). Nevertheless, the average duration of each visit did not significantly increase. Consequently, the weekly time devoted to contacts with patients in the office decreased in most specialities (e.g. from 33.9 hours to 31.1 hours in general practice). But the most salient feature was the reduction of time spent by private practitioners in institutions, hospitals or other "medical/social" organizations. The reduction was obvious among internists, surgeons, paediatricians... It was probably caused by the increased number of practitioners. However, "cohort effect" might have played a role in the matter: as the physicians aged, they were less attracted by activities outside their private office. It is noteworthy that all the above figures were observed among the same practitioners, in 1981 and 1987. Moreover, the proportion of patients invited to come back to the physician's office did not grow, the behaviour of the practitioners remaining unchanged during the period. The study also displayed data about a new group of physicians, who were surveyed for the first time in 1987.

Transducin interactions with rhodopsin. Evidence for positive cooperative behavior.
Transducin and rhodopsin belong to a family of guanine nucleotide-binding (G) protein-coupled receptor systems that provide signal transduction mechanisms resulting in numerous metabolic responses in a variety of cell types. A simple, direct binding assay has been developed to investigate the molecular interactions between transducin and rhodopsin. The binding curves generated by these studies are sigmoidal, indicating an allosteric response. The Scatchard plots of this data display an asymptotic, bell-shaped character representative of the positive cooperative behavior. A Hill coefficient, nH = 1.92, was determined and found to be in close agreement with previous kinetic studies of allosterism described for rhodopsin's catalytic mechanism (Wessling-Resnick, M., and Johnson G.L. (1987) J. Biol. Chem. 262, 3697-3705). The value for Kd app was determined to be 0.05 microM. Bmax values obtained from the binding studies suggest that oligomeric complexes of rhodopsin may be involved in interactions with transducin to form multiple high affinity binding sites for the G protein. The positive cooperative behavior demonstrated in this investigation can provide insight into the molecular basis for regulation of other G protein-coupled receptor systems.

Calcium antagonist treatment in mild forms of cardiomyopathy.
Twenty-one patients with a mild form of cardiomyopathy (with normal ejection fraction but histologically-confirmed hypertrophy of myocardial cells and/or elevated diastolic pulmonary artery pressure during exercise) received 120 mg verapamil t.i.d. or no therapy at all for a period of 2 months in an open randomized cross-over study. Out of the 21 patients, 14 improved clinically, one patient's condition deteriorated and six remained unchanged (p less than 0.05). The mean diastolic pulmonary artery pressure during exercise decreased (25.3 +/- 7.6 to 20.1 +/- 6.6 mm Hg, n = 21, p less than 0.05). At rest, the decrease was only significant in the subgroup with pressures above 12 mm Hg (15.4 +/- 2.7 to 11.1 +/- 4.1 mm Hg, n = 9, p less than 0.05). All other hemodynamic data displayed no significant change. The benefits of verapamil therapy may be attributed to an improvement in diastolic ventricular function. The disturbance in diastolic relaxation might be of greater importance than the disturbance in systolic function in patients with mild forms of cardiomyopathy.

[The functional comfort zone for a human operator controlling a dynamic object].
Objective evaluation of the psychic strain of six operators who performed multiparameter compensatory tracking of the moving object helped to identify the zone of changes of its basic parameters. The control within this zone required a minimum psychophysiological cost (zone of functional comfort). The control beyond this zone was associated either with information overload or with a dramatic increase of the risk of failure. In five operators this led to a significant aggravation of the psychic strain. This study has shown that special identification of the zone of functional comfort in the design of data display devices may be a method of optimizing man's work in the ergatic systems.
