The aim of the study was to evaluate our practice of self-directed learning (SDL) among pre-university students in Malaysia. Respondents provided data on their previous school learning experiences besides present SDL experiences in college. We carried out exploratory factor analysis based on the school data. We did a confirmatory factor analysis using College SDL experiences of students. Given high similarities between the measurement models, we decided to use the original structure of the instrument. Students provided feedback using a questionnaire based on Prociuk’s. A large majority declared that they needed SDL experiences which they lacked while at school. The study also showed that students had rated their SDL experiences in college more positively than in school, on four factors of SDL experiences. Pearson correlations showed that “knowledgeable and organised teachers” and “promotion of active learning” correlated significantly with students’ current satisfaction with SDL in college. 相似文献

X-linked adrenoleukodistrophy is a severe neurodegenerative disorder with impaired very long chain fatty acid metabolism.
The disease associated ABCD1 gene encodes a peroxisomal membrane protein which belongs to the superfamily of ATP-binding cassette
transporters. We investigated eight male X-ALD patients diagnosed among 142 suspected patients referred for investigation.
Plasma levels of very long chain fatty acids were measured at our laboratory using capillary gas chromatography. Eight cases
of childhood X-ALD were diagnosed. This is the first published series of Serbian patients with X-ALD. In addition, diagnosis
identifies carriers, which could be benefit for genetic counselling and prenatal diagnosis. 相似文献

We propose a rapid, simple metodology for routine analysis of human urine to detect vanillylmandelic and homovanillic acid
related to neuroblastoma. The assay were specific capillary gas chromatography with flame ionization detection. In this methodology
an internal standard is used and the procedure involves ethyl ester formation without isolation of the compounds of interest.
The run time is 36 minutes. We also report quantitative results for urinary vanillylmandelic and homovanillic acid in neuroblastoma
patients, demonstrating the diagnostic value of this method. 相似文献
