Objectives : This study was conducted to investigate the deficits of executive function in children with ADHD, Asperger's Disorder(AD), and teaming disorder (LD), and to identify the differential characteristics of executive function deficits among three groups. Methods : The clinical group consisted of 46 children between the ages of 7 and 15 (16 ADHD, 16 LD, 14 AD). Neuropsychological tests for measuring cognitive function, attention and executive function were individually administered to children, and their performance scores were calculated based on the age norm for each test. Results : There was no significant difference in FSIQ, VIQ, and PIQ among the three groups. However, the AD group tended to show higher scores on the subtests of Information, Vocabulary and Digit Span, and lower score on Comprehension subtest than the ADHD and LD groups, while the LD group tended to show the lowest scores on the Information and Vocabulary subtests. On ADS, the ADHD group showed the highest omission and commission errors. All groups showed poor performances belonging to below 25 percentile ranks on executive function tests when compared to the age norms of normative group. The number of completed category on WCST was the smallest in the ADHD group, while the working memory score was the lowest in the LD group. Conclusion : These results suggest that ADHD, LD, and AD children have executive function deficit in common. However, the specific deficit areas in executive function are different for each group.

Purpose: Stress activates the sympathetic nervous system and hypothalamic-pituitary-adrenal (HPA) axis and induces the release of glucocorticoids. Saccharin is 300 times sweeter than sucrose, but does not increase blood insulin levels. Thus, this study was designed to evaluate the effect of saccharin intake in restraint-induced stress response reduction in rats. Methods: Adult male Sprague-Dawley (SD) rats had stress induced by restraint for 2 hours/day for 1 week. Saccharin was provided in sufficient amounts to allow them to intake it voluntarily at 0.1% diluted in water. The Y-maze test and forced swim test (FST) were performed to evaluate cognitive function and the depressive behavior of the rats. The protein expression of the glucocorticoid receptor (GR) in hippocampal cornu ammonis (CA) 1 was investigated by using immunohistochemistry. Results: It was found that, the percentage of alternation in the Y-maze test was significantly (p<.01) higher in the Stress + saccharin group than in the Stress group. Immobility time in the FST was significantly (p<.01) lower in the Stress + saccharin group than in the Stress group. Also, the positive cells of GR in hippocampus CA1 were significantly (p<.05) lower in the Stress + saccharin group than in the Stress group. Conclusion: This study showed that there was an effect of saccharin intake in restraint-induced stress response reduction in rats.

This study investigated the anti-amnesic effect of fermented Ganoderma lucidum water extracts (GW) on scopolamine- induced memory impairment in rats. GW were fermented by the lactic acid bacterium Bifidobacterium bifidum (FGWB), followed by Lactobacillus sakei LI033 (FGWBL). To induce amnesia, scopolamine (1 mg/kg) was intraperitoneally injected into rats 30 min before the behavioral tests. Step-through latencies of rats treated with primary fermented extracts (300 mg/kg, FGWB) and secondary fermented extracts (300 mg/kg, FGWBL) were significantly longer than those of rats treated with GW (300 mg/kg) in the retention trial of the multiple trial passive avoidance test. In the Morris water maze task, FGWBL significantly shortened escape latencies in training trials. Furthermore, swimming times within the target zone during the probe trial with FGWBL were significantly higher than the GW and FGWB treatments. In addition, acetylcholinesterase activities were lower in the brains of scopolamine-treated rats treated with FGWBL. These results suggest that FGWBL could be useful to enhance learning memory and cognitive function via cholinergic dysfunction.

Spectrum sensing is a key technical challenge for cognitive radio (CR). It is well known that multicycle cyclostationarity (MC) detection is a powerful method for spectrum sensing. However, a conventional MC detector is difficult to implement because of its high computational complexity. This paper considers reducing computational complexity by simplifying the test statistic of a conventional MC detector. On the basis of this simplification process, an improved MC detector is proposed. Compared with the conventional detector, the proposed detector has low-computational complexity and high-accuracy sensing performance. Subsequently, the sensing performance is further investigated for the cases of Rayleigh, Nakagami-m, Rician, and Rayleigh fading and lognormal shadowing channels. Furthermore, square-law combining (SLC) is introduced to improve the detection capability in fading and shadowing environments. The corresponding closed-form expressions of average detection probability are derived for each case by the moment generation function (MGF) and contour integral approaches. Finally, illustrative and analytical results show the efficiency and reliability of the proposed detector and the improvement in sensing performance by SLC in multipath fading and lognormal shadowing environments.

수학 과목은 중고등학교 교과과정에서 매우 중요한 과목인 동시에 학생들이 가장 싫어하는 과목중의 하나이다. 본 연구는 중학생의 실제 수학성적을 예측하는 실행기능의 효과를 탐구하였으며, 이 변인의 효과가 다른 심리적 변인의 효과를 통제한 후에도 유의미한지를 검증하였다. 분석 결과 실행기능 수준은 동기와 태도변인을 통제한 후에도 그들의 수학성적을 예측하는 유의미한 변인이었다. 이 변인의 효과는 특히 수학성적이 낮은 중학생의 경우 더 강했으며, 오히려 수학성적이 높은 학생의 경우에는 생물학적 변인의 효과만이 유의미한 것으로 드러나, 성적에 따라 인지적, 심리적 요인을 고려한 다른 유형의 학습지도가 필요함을 시사하였다.
