The purpose of this study is to develop collaboration scripts as an instructional means to facilitate argumentation in computer-supported collaborative learning, and to analyze their effects. To develop collaboration scripts for argumentation, researchers used activity theory as a conceptual framework and refined the design principles by design-based research. Using LAMS, collaboration scripts for argumentation were developed based on the ArgueGraph. To examine their effects, 72 participants were divided into two groups by internal scripts and randomly allocated to one of three external scripts. Applying mixed methods, researchers analyzed argumentation competence related to the cognitive aspect, examined self-efficacy related to the motivational aspect, and identified the factors influencing collaborative learning processes and outcomes. Researchers found that the internal script is a critical factor to determine the dimensions, degrees, and duration of improvement in argumentation competence. That is, learners with higher internal scripts improved highly in the quality of single arguments, while learners with lower internal scripts improved continuously in the quality of argumentation sequences. The effects of the external scripts varied with the internal script levels and supporting periods. Besides, collaboration scripts for argumentation had positive effects on learners' self-efficacy, and learners with higher internal scripts had better self-efficacy. The factors influencing collaborative learning processes and outcomes showed different results depending on the learning context. Therefore, when scripting learner's interaction in CSCL, researchers should design the scripts adaptable to a natural context of activities.

오늘날 3D 캐릭터 애니메이션은 실사영화, 애니메이션, 게임, 광고 등 대다수의 영상물에서 쉽게 접할 수 있다. 캐릭터의 부드러운 움직임은 모션캡쳐(Motion Capture)나 숙련된 애니메이터의 키 프레임(Key Frame) 작업의 결과물일 것이다. 이런 작업들은 고가의 장비나 많은 인력을 요구하고 완성된 결과물은 수정하거나 효과를 주기가 힘들다. 본 연구에서는 3D Studio MAX Script를 이용한 삼차원 회전 값의 연산으로 바이페드(Biped)의 포즈나 애니메이션을 합성하고 보다 사실적인 합성을 위한 방법을 제시하고자 한다.

PS4(Publishing System Side Script System)는 다량의 정보를 효율적으로 제공하기 위한 정보사이트를 보다 빠르고 효율적으로 구축하기 위해 만들어진 스크립트 시스템이다. PS4는 하나의 템플릿에서 하나의 문서만을 생성하던 점에서 탈피하여 탬플릿 수는 줄이면서 보다 많은 문서를 작성할 수 있도록 개발되었다. PS4를 사용하면 템플릿을 최소화하며, PS3(Publishing System Side Script)를 이용하여 서비스 시스템의 자원 사용 및 중복 작업을 최소화 할 수 있다. 또한 데이터베이스와의 연동을 통하여 자료를 효율적으로 관리할 수도 있다.

In this paper, I have implemented the security system using shell script that periodically checking the security elements of unix system for security it transmit to a monitoring server and monitoring many clients. Agent of client executing by crontab scheduler, Environment of server to receive data use restricted TFTP in SunOS. And then, Because of using shell script, apply shell to system with flexible, control performance, and can meet on a sudden situation.

Traditional block cipher Advanced Encryption Standard (AES) is widely used in the field of network security, but it has high overhead on each operation. In the 15th international workshop on information security applications, a novel lightweight and low-power encryption algorithm named low-power encryption algorithm (LEA) was released. This algorithm has certain useful features for hardware and software implementations, that is, simple addition, rotation, exclusive-or (ARX) operations, non-Substitute-BOX architecture, and 32-bit word size. In this study, we further improve the LEA encryptions for cloud computing. The Web-based implementations include JavaScript and assembly codes. Unlike normal implementation, JavaScript does not support unsigned integer and rotation operations; therefore, we present several techniques for resolving this issue. Furthermore, the proposed method yields a speed-optimized result and shows high performance enhancements. Each implementation is tested using various Web browsers, such as Google Chrome, Internet Explorer, and Mozilla Firefox, and on various devices including personal computers and mobile devices. These results extend the use of LEA encryption to any circumstance.

A web application running on the Internet is causing many difficulties for a program developer, and it requires to process multiple sessions at the same time due to the occurrence of excessive traffic. Web applications should be able to process concurrent requests efficiently and in real time. Node.js is a single-threaded server-side JavaScript environment implemented in C and C ++ as one of the latest frameworks to implement event models across the entire stack. Nodes implement JavaScript quickly and robust to achieve the best performance using a JavaScript V8 engine developed by Google. In this paper, it will be explained the operation principle of Node.js, which is a lightweight real-time web server that can be implemented in JavaScript for real-time responsive web applications. In addition, this application was practically implemented through automatic alignment system for group scheduling to demonstrate event-based real-time response web processing.

This study investigates pause positions of Korean students' reading of an English script. 12 natives speakers of English and 18 Korean students were asked to read The North Wind and the Sun. The common pause positions were determined by examining the pauses of the native speakers' readings. Korean students were asked to mark pauses on a script. And then they were trained to put pauses as native speakers of English do. Although some errors have been corrected after the training, others have not been corrected in Korean students' readings. Korean students made fewer errors in marking on the script than in reading the script. They seem to know where to put pauses, but lack of practice makes it difficult to put pause in the right positions when they read. That suggests that teachers should continue to teach students where to put pauses in their reading or speaking English.

The purpose of this paper is to show how to convert the label files of the Buckeye Corpus of Spontaneous Speech [1] into Praat format and to introduce some of the Praat scripts that will enable linguists to study various aspects of spoken American English present in the corpus. During the conversion process, several types of errors were identified and corrected either manually or automatically by the use of scripts. The Praat script tools that have been developed can help extract from the corpus massive amounts of phonetic measures such as the VOT of plosives, the formants of vowels, word frequency information and speech rates that span several consecutive words. The script tools can extract additional information concerning the phonetic environment of the target words or allophones.
