This paper is concerned with the effectiveness of songs in the acquisition of formulaic sequences in the college EFL classroom. The existing research mentions the use of songs in terms of the power of their melodies (Fonseca-Mora, 2000), linguistic features in song lyrics (Abbott, 2002), and the emotional basis of memory (LI & Brand, 2009). Learners' opinions about the use of songs has been ignored, however. In this paper, seven subjects with English ability ranging from advanced (one) intermediate-high (three), intermediate-middle (two), and intermediate-low (one) studied five different pop songs. The results showed that they did not agree with the existing research findings. Rather, they were negative about using songs in the classroom. Their complaints were the burden of using too many hours to memorize lyrics, few language expressions to learn, and too much emphasis on expressions about love and feelings. Students at all levels expressed similar negativity about the use of songs. When their complaints were discussed during interviews, however, their attitude changed from negative to positive. The case study in this paper was on a small-scale but it is suggested that through further research the use of songs could be activated in the EFL classroom. Considering college language learners disregard most existing EFL materials, it appears to be worthwhile to continue further with this kind of research.

Nowadays microblogs have become the most popular platforms to obtain and spread information. Twitter is one of the most used platforms to share everyday life event. However, rumors and misinformation on Arabic social media platforms has become pervasive which can create inestimable harm to society. Therefore, it is imperative to tackle and study this issue to distinguish the verified information from the unverified ones. There is an increasing interest in rumor detection on microblogs recently, however, it is mostly applied on English language while the work on Arabic language is still ongoing research topic and need more efforts. In this paper, we propose a combined Convolutional Neural Network (CNN) and Long Short-Term Memory (LSTM) to detect rumors on Twitter dataset. Various experiments were conducted to choose the best hyper-parameters tuning to achieve the best results. Moreover, different neural network models are used to evaluate performance and compare results. Experiments show that the CNN-LSTM model achieved the best accuracy 0.95 and an F1-score of 0.94 which outperform the state-of-the-art methods.

In simultaneous interpreting, if the syntactic structure of the source language and the target language are very different, interpreters have to wait before being able to reformulate the source text segments into a meaningful utterance in target language. It is inevitable to adapt the target language structure to that of the source language so as not to unduly increase the memory load and to minimize the pause. While such adaptation enables simultaneous interpretating, it results in damaging the perspective coherence of the text. Discovering when such perspective coherence is impaired, and how the problem can be relieved, will enable interpreters to enhance their performance. This paper analyses the reasons for perspective coherence damage by looking at some examples of German-Korean simultaneous interpreting.

The Synchronized Multimedia Integration Language (SMIL) is a declarative markup language based on the eXtensible Markup Language (XML) to define a set of markup tags for synchronizing the timing and positioning relationships between multimedia objects. SMIL makes authoring of TV-like multimedia presentations on the Web easier for applications such as electronic commerce. We present the design and implementation of a JAVA-based SMIL player, which processes different types of media objects using multiple threads. Moreover, its cache engine detects the media type and allocates the proper cache memory for the corresponding media object.

현재, 자동번역의 도메인은 응용 프로그램의 요구에 따라, 점차 문어체에서 대화체(spoken language)로 옮겨가고 있는 추세이다. 본 논문은 대화체가 지니는 특성을 자동번역 시스템을 구성하는 각 모듈별 및 지식 관점에서 분석하였다. 특성 분석을 기반으로 하여, 본 논문에서는 여행 영역을 대상으로 하는 대화체 자동번역시스템의 특화를 수행하였다. 대화체 자동번역을 위한 새로운 지식으로 구조화 번역메모리(Translation Memory)가 도입되었으며, 시스템을 구성하는 각 모듈별로 대화체 특화가 이루어졌다. 또한 기존의 문어체용 기구축 패턴 등이 정비되었으며, 고빈도 대화체 표현에 대한 신규 패턴이 도입되었다. 제안하는 방법의 검증을 위해 수동평가를 수행하였으며, 그 결과, 영한 대화체 자동번역에 있어서 번역률 향상이 있었다.

We study parallel processing techniques for the R programming language of high performance computing technology. In this study, we used massively parallel computing system which has 25,408 cpu cores. We conducted a performance evaluation of a distributed memory system using MPI and of a the shared memory system using OpenMP. Our findings are summarized as follows. First, For some particular algorithms, parallel processing is about 150 times faster than serial processing in R. Second, the distributed memory system gets faster as the number of nodes increases while shared memory system is limited in the improvement of performance, due to the limit of the number of cpus in a single system.

In this paper, various techniques considering the characteristics of computer memory management are suggested, which can be used in the implementation of simplex method. First, reduction technique of indirect addressing, redundant references of memory, and scatter/gather technique are implemented, and the effectiveness of the techniques is shown. Loop-unrolling technique, which exploits the arithmetic operation mechanism of computer, is also implemented. Second, a subroutine frequently called is written in low-level language, and the effectiveness is proved by experimental results. Third, row-column linked list and Gustavson's data structure are compared as the data structure for the large sparse matrix in LU form. Last, buffering technique and memory-mapped file which can be used in reading large data file are implemented and the effectiveness is shown.

What is the foundation of mathematical thinking? Is it logic based symbolic language system? or does it rely more on mental imagery and visuo-spatial abilities? What kind of neural changes happen if someone's mathematical abilities improve through practice? To answer these questions, basic cognitive processes including long term memory, working memory, visuo-spatial perception, number processes are considered through neuropsychological outcomes. Neuronal changes following development and practices are inspected and we can show there are neural networks critical for the mathematical thinking and development: prefrontal-anterior cingulate-parietal network. Through these inquiry, we can infer the answer to our question.

Purpose : This study was to investigate the application of Rhythmic Initiation(RI) in the respect of information processing in motor learning. Methods : A computer-aided literature search was performed in PubMed and adapted to the other databases and the others were in published books. The following keywords were used: Rhythmic Initiation, attention, memory, motor accuracy, feedback, motor learning, motor control, PNF, cognition. Results : The characterization of RI is rhythmic motion of limb or body through the desired range, starting with passive motion and progressing to active resisted movement. This study suggested that the relationship between of RI and motor learning through the respect of information processing, memory, attention and motor accuracy. Conclusion : Only Rhythmic Initiation, specifically focused on the effects of information processing approach, suggesting that RI can be positively influeced on sensory-perception, attention, memory, motor accuracy. however, it is unclear whether positive effects in the laboratory and field can be generalized to improve. In addition, sustainability of motor learning with RI remains uncertain.

작업 기억내에서의 통사처리과정을 살펴보기 위해 생략어를 포함하는 네가지 유형의 대등 연결문을 마지작 단어 읽기 과제를 통해 비교하였다. 특히 통사과정에 관한 설명으로 제시되는, 근접 가설, 작업 기억 가설, 최근 필러 이용 가설의 상대적 설명의 효율성을 검증하고자 하였다. 실험 결과는, 주어가 공통논항인, 표준 어순의 연결문이 다른 세 유형의 연결문보다 이해 시간이 빨랐다. 이 결과는 어느 한 가설로는 설명될 수 없으며, 대안적인 설명으로 작업 기억내에서 이용 가능한 여러 정보의 상호 제약에 의해 이루어짐을 논의 했다.
