The purpose of this study was to assess Greek primary (1st to 6th grade) school children’s dietary habits and the factors
influencing them. Our results show that children know the value of different foods. The socio-economic status of father has
no effect on the attitude of children towards choosing their diet, however, mothers’ educational status appears to have an
effect on their children’s behaviour. Place of residence (urban or semi-rural areas) and gender does not influence their knowledge
about different diets. It was, finally, shown that as children grow older they tend to eat less healthy foods. 相似文献

PURPOSE: Chest radiographs (CXR) are the standard method for evaluating rib fractures in abused infants. Computed tomography (CT) is a sensitive method to detect rib fractures. The purpose of this study was to compare CT and CXR in the evaluation of rib fractures in abused infants. METHODS: This retrospective study included all 12 abused infants identified from 1999 to 2004 who had rib fractures and both CXR and CT (8 abdomen CTs, 4 chest CTs). CT exams had been performed for clinical indications, and were obtained within one day of the CXR. Studies were reviewed by two pediatric radiologists to determine the number, locations, and approximate ages of the rib fractures. A total of 225 ribs were completely (192) or partially (33) seen by CT, and the matched ribs on CXR were used for the analysis. RESULTS: The mean patient age was 2.5 months (1.2-5.6), with seven females and five males. While 131 fractures were visualized by CT, only 79 were seen by CXR (p<.001). One patient had fractures only seen by CT. There were significantly (p<.05) more early subacute (24 vs. 4), subacute (47 vs. 26), and old fractures (4 vs. 0) seen by CT than by CXR. Anterior (42 vs. 11), anterolateral (21 vs. 12), posterolateral (9 vs. 3) and posterior (39 vs. 24) fractures were better seen by CT than by CXR (p<.01). Bilateral fractures were detected more often by CT (11) than by CXR (6). CONCLUSIONS: While this study group is small, these findings suggest that CT is better than CXR in visualizing rib fractures in abused infants. 相似文献

While instructional objectives have provided a cornerstone for the practice and science of instruction, they have also locked us into a lexically based conceptual system. In order to realize the interactive potential of computer-based instructional systems, we need a new way of representing performance. This paper presents the concept of a work model which is a unit of practice which allows replication of both information and interaction. In addition, the work model idea also addresses some of the fundamental problems with objectives such as their inability to capture the richness of terminal behavior or how to relate objectives to content. 相似文献

A mother's question of whether to believe her child's disclosure of intrafamily child sexual abuse is complex, with many factors influencing her conclusion. Variables related to the abuse and to the family's functioning are examined to determine if particular circumstances are too threatening to mothers, resulting in their disbelief. The findings indicate that the age of the victim, nature of the abuse, presence of the mother in the home during the abuse, relationship of the victim to the offender, prior physical abuse of the child, and alcohol abuse by the offender all contribute to mother's conclusion regarding the reported abuse. The majority of mothers do believe their child, with difficult situations and other family stressors occasionally detracting from a mother's willingness to accept the report. 相似文献
