Functional correlations of spatial quantitative EEG and intelligences in a nonalphabetical language group.

This study investigated any functional correlations between intelligences and spatially recorded quantitative electroencephalograms (QEEGs) in a nonalphabetical language group. Participants, between 6 and 8 years old, were sampled in a teaching hospital located at the central Taiwan region. The Chinese Wechsler Intelligence Scale for Children-III (WISC-III) intelligence test and quantitative electroencephalograph recording procedures were both administrated to collect data. Intelligences were divided into two categories, verbal and performance intelligences, for statistical investigations. Statistical analyses of the noncontaminated QEEG dataset investigated the differentiability of each frequency on a single cortical region and coherence between cortical regions. Low QEEG frequencies were found to have a significant correlation with intelligences on some cortical regions. Coherence between symmetric cortical regions was found to be an important factor in predicting intelligences. Results showed the feasibility of functional brain mapping in the particular language population.

Behavior, attitudes and knowledge about antibiotic usage among residents of Changhua, Taiwan.

This study surveyed the behavior, attitudes, and knowledge about antibiotic usage among residents of Changhua County, Taiwan. A questionnaire designed to evaluate general knowledge and attitudes towards antibiotic usage was administered to a total of 1024 adults. The male-to-female ratio was 0.75. All of the 1024 adults were aware of the term "antibiotics". Only 39.2% of subjects had knowledge about basic antibiotic terminology, 69.7% expected that physicians should educate people about antibiotics. There were 7 main findings of this study: (1) 52.7% of subjects considered that physicians advice about the need for compliance was poor; (2) 15.3% of subjects always requested an antibiotics prescription when they suffered from flu-like symptoms; (3) 49.8% failed to comply with prescribed antibiotic regimens; (4) 53.1% of subjects were not aware that antibiotic syrup should be stored in the refrigerator; (5) 27.1% of subjects lacked knowledge about how to deal with the misuse of antibiotics; (6) 9.3% of pregnant and breast-feeding subjects did not have adequate knowledge of the safety of using antibiotics during pregnancy; and (7) 30% of subjects did not know how to obtain information about antibiotic usage. Residents of Changhua County had inadequate or incorrect knowledge about antibiotic usage. The findings of this study imply the need for programs to promote greater education about antibiotics usage in the general population of Taiwan.

General growth mixture modeling for randomized preventive interventions.

This paper proposes growth mixture modeling to assess intervention effects in longitudinal randomized trials. Growth mixture modeling represents unobserved heterogeneity among the subjects using a finite-mixture random effects model. The methodology allows one to examine the impact of an intervention on subgroups characterized by different types of growth trajectories. Such modeling is informative when examining effects on populations that contain individuals who have normative growth as well as non-normative growth. The analysis identifies subgroup membership and allows theory-based modeling of intervention effects in the different subgroups. An example is presented concerning a randomized intervention in Baltimore public schools aimed at reducing aggressive classroom behavior, where only students who were initially more aggressive showed benefits from the intervention.
