수중 환경의 복잡성 때문에 수중통신은 대기중에서의 통신과는 그 차이가 상당한 여러 가지 어려움들을 가지고 있다. 신호는 수중에서 많은 불규칙 소음들에 의해 저하된다. 뿐만 아니라 대역폭의 한계는 수중 통신에서 매우 큰 이슈이다. 그러므로 배열신호 처리 기법은 SNR을 개선에 적당하다. 이 논문에서 소스 추적기법에 기반한 수중 통신을 목적으로 하는 potential 기법을 제안하고자 한다. 또한 다중배열 소나를 이용한 새 추적 모델과 동 소나의 세부 구성을 제시했다. 실험들에서는 샘플 모델과 본 모델상에서 추적 결과의...

This study aims to explore how second language learners’ performance in grammaticality judgment tests (GJTs) vary according to task stimulus and time constraint. Native speakers and learners of English read grammatical and ungrammatical sentences in timed and untimed settings. They were asked to judge the grammaticality of given sentences. In order to investigate the participants’ online behaviors while performing the tasks, eye-tracking methodology was employed. In addition to their...

Liver cancer occurs very frequently worldwide and hepatocellular carcinoma (HCC) accounts for more than 80% of total primary liver cancer cases. In this study, the anticarcinogenic effects of resveratrol against hepatitis B virus (HBV)-induced HCC were investigated by using HBV X-protein-overexpressing Huh7 (Huh7-HBx) human hepatoma cells. MTT assay showed that resveratrol decreased cell viability. Fluorescence-activated cell-sorter analysis showed that resveratrol induced G1 cell cycle arrest...

P-glycoprotein (P-gp) is encoded by the ABCB1 gene and acts as an efflux pump for xenobiotics. In the Border Collie, a nonsense mutation caused by a 4-base pair deletion in the ABCB1 gene is associated with a premature stop to P-gp synthesis. In this study, we examined the full- length coding sequence of the ABCB1 gene in an ivermectin- sensitive Border Collie that lacked the aforementioned deletion mutation. The sequence was compared to the corresponding sequences of a wild-type Beagle and...

Anesthetics are used extensively in surgeries and related procedures to prevent pain. However, there is some concern regarding neuronal degeneration and cognitive deficits arising from regular anesthetic exposure. Recent studies have indicated that brain-derived neurotrophic factor (BDNF) and cyclic AMP response element-binding protein (CREB) are involved in learning and memory processes. Genistein, a plant-derived isoflavone, has been shown to exhibit neuroprotective effects. The present study...

Pro-inflammatory cytokine and brain-derived neurotrophic factor (BDNF) are modulated in post-traumatic stress disorder (PTSD). This study investigated the effects of ibuprofen (IBU) on enhanced anxiety in a rat model of PTSD induced by a single prolonged stress (SPS) procedure. The effects of IBU on inflammation and BDNF modulation in the hippocampus and the mechanisms underlying for anxiolytic action of IBU were also investigated. Male Sprague-Dawley rats were given IBU (20 or 40 mg/kg, i.p.,...

Baicalein (BA), a plant-derived active flavonoid present in the root of Scutellaria baicalensis, has been widely used for the treatment of stress-related neuropsychiatric disorders including depression. Previous studies have demonstrated that repeated restraint stress disrupts the activity of the hypothalamic-pituitary-adrenal (HPA) axis, resulting in depression. The behavioral and neurochemical basis of the BA effect on depression remain unclear. The present study used the forced swimming test...

AMP-activated protein kinase (AMPK), an important regulator of energy metabolism, is activated in response to cellular stress when intracellular levels of AMP increase. We investigated the neuroprotective effects of AMPK against scopolamine-induced memory impairment in vivo and glutamate-induced cytotoxicity in vitro. An adenovirus expressing AMPK wild type alpha subunit (WT) or a dominant negative form (DN) was injected into the hippocampus of rats using a stereotaxic apparatus. The AMPK...
