Escherichia coli O157:H7 is recognized as a significant food-borne pathogen, so rapid identification is important for food hygiene management and prompt epidemiological investigations. The limited prevalence data on Shiga toxin-producing E. coli (STEC) and E. coli O157:H7 in foods and animals in Korea made an assessment of the risks difficult, and the options for management and control unclear. The prevalence of the organisms was examined by newly developed kit-E. coli O157:H7 Rapid kit. For the... -
Oxygen/Glucose Deprivation and Reperfusion Cause Modifications of Postsynaptic Morphology and Activity in the CA3 Area of Organotypic Hippocampal Slice Cultures

Brain ischemia leads to overstimulation of N-methyl-D-aspartate (NMDA) receptors, referred as excitotoxicity, which mediates neuronal cell death. However, less attention has been paid to changes in synaptic activity and morphology that could have an important impact on cell function and survival following ischemic insult. In this study, we investigated the effects of reperfusion after oxygen/glucose deprivation (OGD) not only upon neuronal cell death, but also on ultrastructural and biochemical... -
Effects of In Vitro Exposure to Silica on Bioactive Mediator Release by Alveolar Macrophages

Alveolar macrophages play a pivotal role in the pathogenesis of silicosis since the macrophages may release a wide variety of toxic and inflammatory mediators as well as mitogenic growth factors. In the present study, the effects of in vitro exposure to silica on release of various mediator such as reactive oxygen species, platelet activating factor(PAF), and interleukin-1 (IL-1) by alveolar macrophages were examined. First, hydrogen peroxide release from alveolar macrophages was monitored by... -

목적: 뇌졸중 환자에게 의미 있는 작업을 기반으로 한 양측성 상지 훈련의 효과를 알아보기 위한 예비 연구로 실시되었다. 연구방법: 뇌졸중으로 인한 편마비를 가진 환자 4명을 대상으로 실험군(2명)과 대조군(2명)으로 나누어 진 행되었다. 2016년 5월부터 8월까지 진행하였으며, 대상자 당 총 5주간, 주 3회, 회기 당 60분의 작업기 반 양측성상지훈련 중재와 전통적 양측성 상지 훈련을 각 각 실시하였다. 중재 전 후로 EMG, 가속도계, ARAT, Y-BAT, SIS, COPM를 실시하여 각 군간 비교 하였다. 결과: 실험군은 대조군 보다 노쪽... -

객관적으로 청력역치를 측정하는데 청성뇌간반응(auditory brainstem response, ABR)은 가장 효과적인 유발전위(evoked potential) 검사로 폭넓게 인식되어 왔다. 임상적으로 주로 사용되는 클릭음은 1,000~4,000 Hz의 순음평균역치와 높은 상관관계를 나타내어 1,000 Hz이하의 저주파수의 정보를 얻을 수 없는 단점이 있다. 반면 저주파수 청력을 평가할 수 있는 Toneburst자극을 사용하는 청성 뇌간반응은 주파수 특이성을 가지며 순음청력역치의 500~4,000 Hz를 평가할 수 있으나 파형이 명확치 않아 파형의 해석에서 차이를 보인다.... -
The Effect of Unfocused Written Feedback on L2 Development and Its Relationship with Language Analytic Ability

WCF over six weeks: direct correction (DC), coded indirect correction (CIC), and underline indirect correction (UIC). The fourth group engaged in self-editing without WCF and served as a control group. Results showed that DC and CIC led to more improved accuracy than what was obtained from UIC and self-correction. In addition, the process whereby DC and CIC led to accuracy gains differed. Learners’ LAA was found to be strongly related to both DC and CIC while no relationship was found with UIC. -
Learner Recognition of Recasts and Its Relation with Language Analytic Ability and Communicative Value

ABSTRACT. Not all grammar features are equally noticeable in input. The communicative value of a linguistic feature is one of the important factors that affect perceptual salience. In addition, it is claimed that language learners’ recognition of certain grammar features in incoming input is related to their language analytic ability. However, little research has been conducted to examine the relationship between these two issues. Thus, this study explored how learners recognized recasts that...
