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.

Recently, many malicious users have attacked web browsers using JavaScript code that can execute dynamic actions within the browsers. By forcing the browser to execute malicious JavaScript code, the attackers can steal personal information stored in the system, allow malware program downloads in the client's system, and so on. In order to reduce damage, malicious web pages must be located prior to general users accessing the infected pages. In this paper, a novel framework (JsSandbox) that can monitor and analyze the behavior of malicious JavaScript code using internal function hooking (IFH) is proposed. IFH is defined as the hooking of all functions in the modules using the debug information and extracting the parameter values. The use of IFH enables the monitoring of functions that API hooking cannot. JsSandbox was implemented based on a debugger engine, and some features were applied to detect and analyze malicious JavaScript code: detection of obfuscation, deobfuscation of the obfuscated string, detection of URLs related to redirection, and detection of exploit codes. Then, the proposed framework was analyzed for specific features, and the results demonstrate that JsSandbox can be applied to the analysis of the behavior of malicious web pages.

Objectives : The Major Essentials of Huangdi's Internal Classics Plain Questions (黃帝內經素問大要, MEHP) is one of the late-Chosun's literate physician Lee Gyoojoon (李圭晙, 1885-1923)'s main work, which is known to have logically proofread the Huangdi's Internal Classics Plain Questions (黃帝內經素問, HP). This study aims to examine two elements of the text: (1) the types of MEHP currently in circulation; (2) the types of publications of HP to be the MEHP's original script. Methods : In this study, basically bibliographical analyses of the form and contents was utilized about the types of MEHP and HP. However, to compare the sentences and phrases between prints, I've used 20 examples that Qian Chaochen (钱超尘) had proposed in his preceding studies. Also, regarding Lee Wonse (李元世)'s proofreading on the MEHP in 1999, I've used interviews of his students. Results : First, I've discovered that there are three versions MEHP in circulation: the woodblock printed version; Lee Wonse's handwritten version; Lee Wonse's proofreading version; and confirmed that Lee's proofreading version should be regarded as good version of MEHP. Also, I've discovered the possibility of other types of printed versions of the MEHP in existence, which is considered Lee's handwritten version's original draft. Second, I've confirmed that the original script of HP, which Lee Gyoojoon utilized for MEHP, is indeed not Gu Congde (顧從德) printed version HP, however, is the Chosun's bureau for military drill (訓練都監) printed version HP. Conclusion : Through this study, I've provided strong evidence that Lee Gyoojoon's MEHP is a unique and original research completed within the traditional realm of Korean medicine, which possesses the universality of Eastern Asian medicine represented by Huangdi's Internal Classics (黃帝內經).

인터넷이 대중화 되면서 내부 데이터베이스로 관리되고 있는 정보를 동적 웹 서버 페이지를 작성하여 웹으로 제공하는 다양한 웹 어플리케이션 개발이 수행되고 있으나, 대부분의 경우 체계적인 개발 방법론의 채택 없이 직접 프로그램을 작성하거나, 규모에 맞지 않는 대규모 개발 방법론을 적용하여 개발의 효율성을 떨어뜨리고 있다. 웹 어플리케이션이 체계적인 개발 방법론을 따르지 않고 스크립트 언어를 사용하여 임의개발 됨에 따라 프로그램 개발의 생산성, 유지 보수성, 그리고 재 사용성을 저하시키게 된다. 본 논문에서는 빠르고 효과적인 스크립트 기반의 웹 어플리케이션 개발을 위하여 데이터베이스를 이용한 동적 웹 서버 페이지 자동 작성 도구를 설계하고 이를 구현하였다. 데이터베이스를 이용한 동적 웹 서버 페이지 패턴을 분석하여 정형화된 스크립트 모델을 제시하고 데이터 바운드 컨트롤 태그 생성기를 표준 스크립트로 작성하여 웹 어플리케이션 개발과 유지보수에 활용되어 생산성 향상에 기여할 수 있다.

Today the company's brand sites are in tendency locating as a handy method to administrate company vision, value and image. So this study tried to examine the aspects of storytelling around Amore Pacific's brand site. To secure the discussion's centrality and concreteness, two issues are considered to be aimed in methodology. First, the menus of relevant site were examined to see if they are securing minimal narrative. This was an attempt to discuss the minimum narrativity that target text is supposed to possess, to objectify little more the term 'storytelling.' After considering the menus of relevant site through narratological ideas of Gerald Prince, the menus that satisfy the level of minimum narrative were hardly seen. Even 'OUR STORY', showing the intention of unraveling the vision and values within the company brand by stories, is not seemed to be reaching universal, objective storytelling. Second, pragmatic, reception theory were applied as another standard to judge storytelling possibilities of Amore Pacific's brand site. Roger C. Schank's script theory, being considered in the field of cognitive linguistics and cognitive psychology, became a handy tool for examining the interactions and its meaning between brand sites and its visitors. As a result, the relevant site could be seen as attempting storytelling following time sequence, through narrator kindly explaining 'visual image-event.' And it was conjecturable that, because of such function of narrator, visitors finishes storytelling in a personal shape by operating internal story based script. This study examined the level and methods of storytelling limited in online environment called as company brand site. But more studies are needed to be in progress, such as about the ways for company websites or brand sites to have an effective, continuous influence on potential consumers, narrator set-up ways suitable for character of subordinate menus, organizations of minimum narrative and so on.

The purpose of this research was conducted to formative processes and to interpret premarital adult's sexuality meaning. The interviews have been executed based upon ethnography approach and method of interview in depth within the framework of the Weis's sexual script theory (1998) and parent-children relation. The interview in depth has been conducted with unmarried 7 males and 8 females inclusive of college students, total 15 persons who were born 1974-1980 and living in Seoul and nearby suburban areas. A period of interviews were carried out from September until December 2003. Each interview was executed for 2 to 4 hours apiece, and each person had 2 to 4 interviews during the period. The result of analysis of the sexuality scripts theory from three different views indicates that the female informants appeared to rationalize the fact that traditional concept of the chastity as defined by the socio-cultural level has been changed. It also indicated that there were very few sex educations in the society at large except for the public medias including the Internet. The interrelation level indicates that positive interaction with the opposite sex has affected them in the course of their building up desirable personal relationship in the society and uplifting their sense of self-esteem. The internal level of sexuality, it is much dependent on the extent of individual inner recognition of sexuality. The parent-children relation view of sexuality, the most influential factor for their communication on sexuality lies in the extent of their realization on how positively their parents recognize their children.
