This paper presents an artificial bee colony (ABC) algorithm for structural optimization of planar and space trusses under stress, displacement and buckling constraints. In order to improve the performance of the classic ABC algorithm, modifications in neighborhood searching method, onlooker phase, and scout phase are proposed. Optimization of different typical truss structures is performed usi...

OBJECTIVE To identify perinatal and neonatal risk factors associated with developmental coordination disorder (DCD) in very low birthweight children (VLBW: <1250 g). DESIGN Retrospective design with prospectively collected cohort. SETTING Neonatal Follow-Up Program, Vancouver, Canada. PATIENTS 157 VLBW children assessed at 4-5 years who were free of cerebral palsy or major neurological im...

The parent-rated Developmental Coordination Disorder Questionnaire (DCDQ) has been revised to incorporate a wider age range, including adolescence. In this exploratory study, internal consistency and validity of the DCDQ-2007 was assessed using a community-based sample of 87 adolescents. Psychometric properties of the DCDQ-2007 were investigated and concurrent validity, sensitivity, and specifi...

Children with Developmental Coordination Disorder (DCD) often experience difficulties in handwriting. The current study examined the relationships between three motor assessments and the spatial and temporal consistency of handwriting. Twelve children with probable DCD and 29 children from 7 to 12 years who were typically developing wrote the lowercase letters "e" and "l" in cursive and printed...

This cross-sectional and exploratory study aimed to compare motor performance and electroencephalographic (EEG) attention levels in children with developmental coordination disorder (DCD) and those with typical development, and determine the relationship between motor performance and the real-time EEG attention level in children with DCD.Eighty-six children with DCD [DCD: n = 57; DCD and attent...

BACKGROUND Little is known about the nature of the host immune response to Mycobacterium abscessus complex (MABC) infection. The aim of the present study was to investigate whether alterations in serum immunomolecule levels after treating MABC lung disease patients with antibiotics can reflect the disease-associated characteristics. METHODS A total of 22 immunomolecules in 24 MABC lung diseas...

The purpose of this study was to examine the relationship between motor skill impairments and motor imagery ability in children with autism spectrum disorders (ASD). The participants were 19 children with ASD, aged 7 16 years. We conducted two tasks: movement assessment battery for children-2 (MABC-2) and hand rotation task. The MABC-2 is a motor test that can assess total motor ability, and th...

BACKGROUND Impaired motor development can significantly affect a child's life and may result in an increased risk of a range of physical and psychological disorders. Active video game (AVG) interventions have been demonstrated to enhance motor skills in children with Developmental Coordination Disorder (DCD); however a home-based intervention has not been assessed. OBJECTIVES The primary aim ...
