[Analysis and spatial description to correlative factors on food hygiene appeal and food poison in restaurants of city zone in Qingdao].

OBJECTIVE: To study some factors that affected food poison and appeals in restaurants which were hidden danger on the cards. METHODS: Data on food hygiene events from 2002 to 2004 in restaurants of 14 blocks which were located in the important city zone of Qingdao were collected and studied. The spatial distribution was conducted by means of Geographic Information System (GIS). Possible factors related to food hygiene events were investigated and analysed by NCSS Data statistics software. information of every block were marked on digitalized map by ARCVIEW3.2a software in order to show the spatial distribution of food hygiene events palpably in different areas in the course of three years. RESULTS: It was showed that air temperature, humidity, sunlight length were the important factors of food poison. Average amount of guests and floating population related to administration level of sanitation, the level of sanitation administration, geography location, business status of restaurants related to their status of food sanitation. CONCLUSION: This study showed the method that analysed and studied status of food sanitation from different areas by GIS were effective, simple and palpable.

[Graphic analysis of spatial changes in the blood vessels in arterial hypertension].

Graphical models of normal vessels and possible abnormal changes thereof (muscular coat hypertrophy or atrophy, and narrowed or intact vascular lumen) have been constructed on the basis of morphometric studies of arteries and arterioles of normal human and white rat heart, liver, brain, lungs, kidneys, stomach, pancreas and small intestine. It is demonstrated that the wall thickness-to-lumen diameter ratio or any similar parameters cannot be used as an unequivocal indicator of vascular change, therefore neither muscular coat hypertrophy, nor narrowed lumen should be regarded as proven in cases of arterial hypertension. The results of the measurement of wall thickness and external as well as inner vascular diameter should be represented as a three-dimensional model for correct assessment of vascular morphogenesis, biomorphosis or pathomorphosis.

Visual mechanisms for the analysis of spatial pattern.

After a brief outline of the structure and electrophysiology of the normal visual pathways, the responses, as revealed by psychophysical studies, of the visual system to spatially and temporally varying stimuli are reviewed. An appropriate network model, involving two sequentially organized classes of visual channel, is presented. Examples are given in which the psychophysical methods developed to analyse the normal visual pathways are applied to cases in which these pathways are defective (amblyopia, albinism, hemianopia, parietal cortical lesion, inhibitory central colour vision defect). These cases not only illustrate the value of psychophysical techniques in analysing disturbances of visual function but are also suggestive of the mechanisms involved in higher processing of the retinal image.

The analysis of spatial phase in amblyopia.

Anomalies in the contrast sensitivity functions of amblyopes are usually insufficient to account for the degree of visual deficit found in more complex tasks. Evidence is presented that many of the defects of amblyopic vision arise from a failure to encode the spatial phase relationships between detectable components of different spatial frequencies. It appears that visual processing in amblyopia occurs over a more truncated frequency range than is implied by detection experiments.
