The current study aimed to examine university students' perceptions of the positive effects of L2 oral presentations in terms of communication skills and future employment. The participants were 13 undergraduate students enrolled in L2 oral presentation classes at the beginner or intermediate level. This study followed a qualitative research approach using in-depth and semi-structured interviews as the primary method. The findings revealed that students largely exhibited the benefits of oral presentations in three ways: by enhancing L2 proficiency, building confidence in public speaking, and gaining competitive advantages in their future careers. As a challenge for L2 learners, oral presentations were considered fundamental to develop effective communication skills in academic and professional contexts.

The present study was to investigate the developmental change of adolescent's theory of mind. In addition, the relations between theory of mind and the social competence were investigated. Sixty students in each the 6th and 8th grade group were participated in this study. Adolescents' understanding of mind were measured by four kinds of mindreading tasks; the second-order false belief tasks, understanding the ambiguous social behaviors tasks, understading the hidden meaning of a figurative statement tasks, and the "faux pas" tasks. Social skills were measured by social skill scales. Eighth graders performed better than the 6th graders on the understanding the ambiguous social behaviors tasks and faux pas tasks but not on the second-order false belief tasks and understanding the hidden meaning of figurative statement tasks. The results suggests that the mindreading ability continues to develop during the adolescence, especially the ability to interpret others' ambiguous social behaviors by reading their mental states and the ability to understand that a person says a faux pas it is due to a mistaken belief. In addition, the understanding the ambiguous social behaviors tasks was found to be the best task to predict social behaviors. The results suggests that the mindreading ability would be a significant explanatory factor on social competence.

We introduce an error correcting 4/6 modulation codes for holographic data storage, and simulate under adding mis-alignment noise. The holographic data storage has two-dimensional intersymbol interference. To increase the channel performance, it is necessary to use modulation code. Furthermore, if the modulation code has trellis structure, error correcting capability is added. The error correcting 4/6 modulation code shows better performance than conventional modulation codes with and without mis-alignment noise.

국어 교과는 말하기 듣기, 읽기, 쓰기 영역으로 구성되어 있으며, 높은 수준의 창의적 사고력을 길러준다. 국어 교과에서 받아쓰기는 우리나라 초등학교 교육 현장에서 가장 기본적으로 활용되고 있으며 현행 국어과의 교육과정에서 중요하게 다루어지고 있다. 그러나 매 회의 받아쓰기 문제지의 문항을 타당성과 신뢰도를 고려하여 조정하여 지도하기는 어려움이 있다. 본 논문에서는 이러한 단점을 보완하기 위해 초등학교 교육 현장에서 사용되는 여러 가지 형태의 받아쓰기와 교과서를 분석하여 문장의 받아쓰기 등급을 정하였다. 문장의 받아쓰기 등급을 가지고 입력한 난이도에 따라 정해진 문장 받아 쓰기 등급이 같으면 받아쓰기 문제로 선택이 되고 문장 받아쓰기 등급과 다르면 다른 문장을 탐색하게 하였다. 최종적으로 선택된 문제는 여러 등급의 문제로 구성함으로써 문제의 타당성과 신뢰도를 높이고, 창의적인 국어사용 능력을 향상시키도록 하였다.

언어는 모든 교육에서 중요한 역할을 담당하므로 국어 교과목은 교육의 기본 목표인 언어사용의 신장을 위해서 중요하게 다루어지고 있다. 언어발달을 위한 국어 교육활동은 듣기, 말하기, 읽기, 쓰기의 네 가지 영역에 기초를 두고 있으며 학생들의 흥미를 유발할 수 있는 쌍방향 멀티미디어를 이용하면 이러한 영역의 학습효과를 증가시킬 수 있다. 그러나 기존의 웹사이트의 개발 사례를 살펴보면 교과서 중심인 일방적인 제사만이 구현되어 있다. 따라서 본 논문에서는 흥미와 자발적인 참여를 유발하고 행동한 것에 대해 즉각적인 반응(Feedback)을 주는 애니메이션과 음성, 효과음, 높이, 학습, 게임으로 결합된 오락적인 쌍방향 멀티미디어 웹 컨텐츠를 개발하여 언어를 배우는 어린이들의 학습능력의 향상과 창의적인 언어 활동의 증대에 기여하고자 한다. 특히, 이 시스템의 큰 특징은 학생에 대한 학습 결과를 도출하고 이에 대한 해결책 및 각종 정보를 추출하여 학습진단 결과, 재학습, 학습독력의 형태로 학생 개개인에게 메일로 보내는 학습 통합관리 기능을 포함하고 있다는 것이다.

난독증자란 지능점수에서 예견하는 것보다 유의하게 낮은 읽기 수준 능력을 가진 사람들이다. 국내의 경우 난독증에 대한 연구가 미진하여 외국의 검사도구를 번역하여 사용하고 있지만, 언어의 경우 민족의 특성과 언어의 특성이 매우 크기 때문에 외국의 검사도구를 그대로 가져오기에는 무리가 있다. 본 논문에서는 난독증 환자를 검사 하고 그 검사 결과에 따라 분석을 할 수 있는 검사도구를 설계하는데 있어 키 반응 검사기의 구현시의 문제점과 문제점을 해결하는 방법을 제시하고자 한다. 다양한 컴퓨터 환경에서의 실험을 통하여 일반적인 키 반응 검사기의 문제점을 보이고 구현한 키 반응 검사기가 검사도구로서의 정확도를 유지하고 있음을 보인다.

Patients of dyslexia have an reading disorder marked by the occurrence of semantic errors. Because there is little understanding of dyslexia in korea, we use a translation version of foreign tester for testing the patients of dyslexia. However, the foreign testers is not suitable for testing the korean patients, because language is sensitive to national culture and trait. In this paper, we propose a model of tester for dyslexia Which is used for classification and analysis of korean patients. In addition, we show some characteristics of the implemented tester by a performance study.

In this paper, we present a new survivor path memory management method and a dedicated hardware architecture for the design of high-speed Viterbi decoders in modern digital communication systems. In the proposed method, a novel use of k-starting node number deciding circuits enables to acheive the immediate traceback of the merged survivor path from which we can decode output bits, and results in smaller survivor path memory size and processing delay time than the previously known methods. Also, in the proposed method, the survivor path memory can be constructed with ease using a simple standard dual-ported memory since one read-pointer and one write-pointer, that are updated at the same rate, are required for managing the survivor path: the previously known algorithms require either complex k-ported memory structure or k-times faster read capability than write. With a moderate hardware cost for immediate traceback capability the proposed method is superior to the previously known methods for high-speed Viterbi decoding.

Objectives: The aim of this study was to develop the computerized Comprehensive Learning Test-Reading (CLT-R) to evaluate the cognitive processes and achievements related to their basic reading ability and identify dyslexia in children and adolescents in South Korea. We also obtained the normative data and evaluated the reliability and validity of the test. Methods: We developed the CLT-R, including the word attack/nonword decoding, paragraph reading, sound blending, nonword repetition, rapid automatized naming, letter-sound matching, visual attention, orthography awareness, and digit span tests, for the purpose of diagnosing dyslexia. We investigated the reliability and validity of the tests and gathered the normative data from 399 subjects (male 48.9%), aged 5-14 years, from the last grade in kindergarten to middle school, dwelling in Seoul and Gyeonggi Province, South Korea. Results: No statistical differences were observed between the means of the tests and retests of the CAT. The mean of the correlation coefficient of the test-retest scores was 0.85. According to the construct validity test calculated by principal constant analysis using the oblique rotation method, 4 factors explained 70.0% of the cumulative variances. In addition, the normative data were obtained for all of the CLT-R subtests. Conclusion: The computerized CLT-R can be used as a reliable and valid tool to evaluate the reading achievement and reading related cognitive process in Korean children and adolescents in schools, clinics, and research institutes.

Objectives: This study was focused on the influence of chronic aircraft noise exposure on children's continuous performance, intelligence and reading skill. Methods: We enrolled 586 children in 4-6th grade of 7 primary schools near air base in Korea. Continuous performance was measured using the computerized ADS program. We analyzed 477-512 children on the visual continuous performance test, auditory continuous performance test, intelligence test, and reading and the vocabulary test. Intelligence was measured using vocabulary, digit span, block design, and digit symbol tests of K-WISC-III. Results: The commission error and variability deviation of auditory continuous performance test and reading test were significantly higher among children in schools with the helicopter noise and the fighting plane noise compared to children in the low noised schools. Conclusion: There was a possibility that chronic aircraft noise exposure was associated with impairment of the school performance. The result of our study also shows chronic aircraft noise was associated with reading ability.
