Massive die-offs of Bufo bufo gargarizans were observed in May 2008 in Mangwal
Gee, Korea. To find out the causes for this disaster several different elements
were examined: pH, total nitrogen, dissolved oxygen (DO), and dissolved heavy
metal, suspension, introduced species, habitat change, disease, temperature
changes, and precipitation and humidity....
The efficiency of cellulose hydrolysis under straight saccharification and simultaneous saccharification and fermentation (SSF) conditions was evaluated using three lignocellulosic materials (switchgrass, cornstover, and poplar), which had been pretreated with dilute sulfuric acid under conditions which optimized xylose concentrations in the prehydrolysate liquid. Yields of glucose, cellobiose and ethanol obtained...
The effect of salt (0, 0.9, 1.7, 2.5%) and pH (range 4
to 10) on surimi gels made from Pacific Whiting (Merluccius
productus) was investigated. Gel-forming ability was measured
by the torsion test. In general, surimi gels
increased in gel strength with increased pH. Breaking shear
stress increased to a...
This study described how and why a Korean elementary teacher taught mathematics as he did. Specifically, the study sought to describe his beliefs about the teaching and learning of mathematics and relate them to patterns of classroom interaction and norms.
An ethnographic inquiry guided the study of one third grade...
This dissertation introduces a method which
can simulate multi-dimensional Gaussian random
processes by the superposition of sine functions
The fast Fourier transform technique is incorporated into the simulating method to facilitate
saving of computer time.
In view of the fact that the fast Fourier
transform play important roles in digital...
A single oral dose of DDT, ranging from 40 to 200 mg/kg, had
a drastic effect on the in vivo acetate metabolism in rats. The normal
elimination pattern of the expired ¹⁴CO₂ from ¹⁴C-labelled
acetate was distorted, and the rate of output of the ¹⁴CO₂ was decreased.
The ratio of...
School-aged children with disabilities have difficulty in meeting current physical activity guidelines (Stanish et al., 2019). As such, there is a need for providing effective physical activity promotion programs for school-aged children with disabilities. School settings can be the right place to promote physical activity for children with disabilities because...
Sleep is an active process that affects an individual's daily functioning and physical and mental health. It is also beneficial for an individual's overall health and well being. Children with autism often have difficulty sleeping. One common complaint from parents of children with autism is that these children lack sufficient...
The benefits of physical activity (PA) are well established (USDDHS, 2008). Concern over the high rate of childhood obesity, however, has highlighted the emphasis of PA. Yet, children and adolescents are not obtaining the recommended amount of PA (CDC, 2011). Physical education (PE) has been recognized as an important source...
Alterations in gait patterns are commonly observed in individuals with transtibial amputation (TTA) who use a prosthesis. Current commercially available ankle-foot prostheses (AFP) offer very little range of motion (ROM) at the ankle joint. Previous researchers have hypothesized that lack of ankle ROM significantly contributes to alterations in TTA gait...
