Analysis of residents' food safety satisfaction from the perspective of income heterogeneity.

Food is the paramount necessity of the people, while food safety is the priority. Facing the increasingly serious food safety problems in China, how to improve food safety has become the responsibility of the whole society, and also the obligation of social development. Based on the 8000 residents' survey data, the ordinal logistic model was used to analyze the residents' satisfaction with food safety.

Effects of audio-visual aids on foreign language test anxiety, reading and listening comprehension, and retention in EFL learners.

This study examined the effects of audio-visual aids on anxiety, comprehension test scores, and retention in reading and listening to short stories in English as a Foreign Language (EFL) classrooms. Reading and listening tests, general and test anxiety, and retention were measured in English-major college students in an experimental group with audio-visual aids (n=83) and a control group without audio-visual aids (n=94) with similar general English proficiency. Lower reading test anxiety, unchanged reading comprehension scores, and better reading short-term and long-term retention after four weeks were evident in the audiovisual group relative to the control group.

Cortical shape and curvedness analysis of structural deficits in remitting and non-remitting depression.

In morphometric neuroimaging studies, the relationship between brain structural changes and the antidepressant treatment response in patients with major depressive disorder has been explored to search depression-trait biomarkers. Although patients were treated with serotonin-related drugs, whether the same treatment resulted in remission and non-remission in depressed patients is currently under investigation. We recruited 25 depressed patients and 25 healthy controls and acquired volumetric magnetic resonance imaging of each participant.

Using three-dimensional multigrid-based snake and multiresolution image registration for reconstruction of cranial defect.

In cranioplasty, neurosurgeons use bone grafts to repair skull defects. To ensure the protection of intracranial tissues and recover the original head shape for aesthetic purposes, a custom-made pre-fabricated prosthesis must match the cranial incision as closely as possible. In our previous study (Liao et al.

Quantifying cerebellar atrophy in multiple system atrophy of the cerebellar type (MSA-C) using three-dimensional gyrification index analysis.

Multiple system atrophy of the cerebellar type (MSA-C) is a degenerative neurological disease of the central nervous system. This study employed a method named, "surface-based three-dimensional gyrification index" (3D-GI) to quantify morphological changes in normal cerebellum (including brainstem) and atrophied cerebellum, in patients with MSA-C. We assessed whether 3D-GI can exclude gender and age differences to quantify cerebellum and brainstem atrophy more accurately.

A hybrid strategy to integrate surface-based and mutual-information-based methods for co-registering brain SPECT and MR images.

Co-registration of brain SPECT and MR images has been used extensively in clinical applications. The complementary features of two major co-registration methods--surface- and mutual-information-based (MI-based)--motivated us to study a hybrid-based scheme that uses the surface-based method to achieve a quick alignment, followed by the MI-based method for fine tuning. Computer simulations were conducted to evaluate the accuracy and robustness of surface-, MI-, and hybrid-based registration methods by designing different levels of noise and mismatch in the registration experiments.

Three-dimensional reconstruction of cranial defect using active contour model and image registration.

In neurosurgery, cranial incisions during craniotomy can be recovered by cranioplasty--a surgical operation using cranial implants to repair skull defects. However, surgeons often encounter difficulties when grafting prefabricated cranial plates into defective areas, since a perfect match to the cranial incision is difficult to achieve. Previous studies using mirroring technique, surface interpolation, or deformed template had limitations in skull reconstruction to match the patient's original appearance.

Cortical complexity analysis of patients with bipolar disorder using three-dimensional gyrification index.

Bipolar disorder (BD) is a common affective disorder. In morphometric brain imaging studies, BD subjects have atrophic gray matter, especially in the prefrontal area. These structural abnormalities could involve the change of cortical shape.

A comparison between the surface-based and mutual-information-based methods for co-registering SPECT and MR images.

Single photon emission computed tomography (SPECT) and magnetic resonance (MR) images are two common modalities in brain imaging society. Co-registration of brain SPECT and MR images has been used extensively in a number of clinical applications. The surface-based method and the mutual-information-based method are two major co-registration methods.
