Objective-It was proposed that the ability to recognize facial emotions is closely related to complex neurocognitive processes and/or skills related to theory of mind (ToM). This study examines whether ToM skills mediate the relationship between higher neurocognitive functions, such as reasoning ability, and facial emotion recognition. Methods-A total of 200 healthy subjects (101 males, 99 females) were recruited. Facial emotion recognition was measured through the use of 64 facial emotional stimuli that were selected from photographs from the Korean Facial Expressions of Emotion (KOFEE). Participants were requested to complete the Theory of Mind Picture Stories task and Standard Progressive Matrices (SPM). Results-Multiple regression analysis showed that the SPM score (t=3.19, p=0.002, β=0.22) and the overall ToM score (t=2.56, p=0.011, β=0.18) were primarily associated with a total hit rate (%) of the emotion recognition task. Hierarchical regression analysis through a three-step mediation model showed that ToM may partially mediate the relationship between SPM and performance on facial emotion recognition. Conclusion-These findings imply that higher neurocognitive functioning, inclusive of reasoning, may not only directly contribute towards facial emotion recognition but also influence ToM, which in turn, influences facial emotion recognition. These findings are particularly true for healthy young people.

증권시장이 커짐에 따라 홈트레이딩시스템(Home Trading System)을 이용한 증권거래가 활발해지고 있다. HTS는 주식시세 조회를 비롯한 매매상담 등의 많은 기능을 제공하고 있다. 그러나 사용자의 편의성과 효용성을 중심으로 한 기능은 개발되고 적용되고 있지만 개인정보 및 거래의 안전성에 대한 보안기능은 미흡한 실정이다. 본 논문은 키로깅과 스니핑을 통해 HTS의 보안서비스를 분석하여 많은 개인정보가 노출됨을 설명한다. 그리고 취약점을 파악하여 HTS가 가져야할 바람직한 평가기준을 제시한다. As stock market gets bigger, use of HTS(Home Trading System) is getting increased in stock exchange. HTS provides lots of functions such as inquiry about stock quotations, investment counsel and so on. Thus, despite the fact that the functions for convenience and usefulness are developed and used, security functions for privacy and trade safety are insufficient. In this paper, we analyze the security system of HTS service through the key-logging and sniffing and suggest that many private information is unintentionally exposed. We also find out a vulnerable point of the system, and show the advisable criteria of secure HTS.

This study analyzed the effects of intensive reading in English on the reading fluency and attitude about reading in elementary school students. The subjects were fifth-grade students in a large metropolitan city in the southern region of Korea. To measure the effects of intensive reading, DIBELS (The Dynamic Indicators of Basic Early Literacy Skills)program, a set of procedures and measures for assessing the acquisition of early literacy skills, was used. The results indicated that intensive reading enhanced students’ reading fluency by facilitating the learning of reading skills. Also, Students became more confident about their English reading skills.
