최근 외신을 통해서 보도된 원숭이를 이용한 BCI (Brain-Computer Interface) 실험에 관한 보도 (Carmena et al., 2003)나 배우 Keanu Reeves가 세 편에 걸쳐서 열연한 영화 Matrix를 통해서나 뇌-컴퓨터 접속이라는 주제가 대중적으로 많은 인기를 끌고 있다. 배우 KeanuReeves는 1995년에도 Fox 영화사에서 제작된 Jonny Mnemonic Superbit Collection(국내 소개명 코드명J)라는 영화에서 뇌-컴퓨터접속기술을 소개한 바 있는데 그리 큰 인길르 끌지는 못하였다가 최근 몇 년간에 걸친 Matrix 쓰리즈에서 뇌-컴퓨터 접속기술을 범대중적으로 소개하는데 성공하였다.

In introducing memory methods in various educational fields, programs in a mobile environment can be used for the purpose of increasing accessibility and enhancing the effectiveness of education. It is much easier to remember words with meaning than to remember numerical information such as years. From the standpoint of increasing the educational effect, the part that needs to be supplemented with the help of the application can be said to be numerical information. Most studies related to conventional numerical memory have focused on the form that helps memory by imaging numbers. In the paper on memory-based meta-record algorithms in the mobile environment, the application developed in the previous study attempts to supplement this by discovering and simply modifying the user's mistakes in the entered numerical information. In this study, we aim to increase the memory rate by constructing metadata based on personalized log information and correcting mistakes. To do this, applications suitable for the mobile environment are developed, a structure of meta-record data is proposed, and meta-record application algorithms are implemented and evaluated.

This study investigated the background of the first and revised editions of the Han-Un Decimal Classification(HUDC), and analyzed their relationships to and influences on other major related classification systems. HUDC was compiled in 1954 and revised in 1981. HUDC was influenced by NDC in most classes of main classes and mnemonic schedules, and influenced by KDCP in the classes Religion, Language and Literature.

가상기계란 하드웨어로 이루어진 물리적 시스템과는 달리 소프트웨어로 제작되어 논리적인 시스템 구성을 갖는 개념적인 프로세서이다. 가상기계 기술은 기계의 프로세서나 운영체제가 바뀌더라도 응용프로그램을 변경하지 않고 사용할 수 있다는 장점이 있다. 최근에는 GVM, KVM 등 모바일 단말기를 위한 가상기계들이 개발되면서 그 중요성이 더욱 부각되고 있으며 특히, 임베디드 시스템을 위한 가상기계 기술은 모바일 디바이스와 디지털 TV 등의 다운로드 솔루션에 꼭 필요한 소프트웨어 기술이다. 본 논문에서는 바이트코드, MSIL 등 기존의 가상기계를 위한 어셈블리 언어들의 분석을 기반으로 하여 임베디드 시스템을 위한 가상기계의 표준 중간 언어인 STL(Standard Intermediate Language)을 제안하고 니모닉(Mnemonic)을 정의한다. SIL은 SIL Assembler에 의해 EVM의 실행 파일인 *.evm의 형태로 번역되며 객체지향 프로그래밍 언어와 순차적인 프로그래밍 언어를 모두 수용할 수 있는 특징을 지닌다.

The tool wear that is developed by long-term machining in mold manufacturing with machining center makes a severe influence to the accuracy and the surface roughness. In this reason, tool-wear supervising system which has guaranteed high accuracy and high speed is needed to improve the measurement quality. Touching probe and touch sensor are widely used to measure the tool profile at on-machine measurement. In this paper, using the newly developed electric touch point measuring system, the Automatic Tool Compensation System is developed to correct the error of tool diameter resulted from the wear, and the operating method of this system is also provided.

Soon after joining the Canadian Confederation in 1867, the province of Quebec adopted the phrase Je me souviens ("As I recall") as its 'national' motto, although many Qu?b?cois do not remember today what they were supposed to memorize, as collective subject, when their government voted this motion. My thesis is that contrary to other countries which have a strong sense of history based on a secular tradition, this process was more complicated in Quebec - as if a collective memory loss lied at the heart of it's history. Through a rereading of Hubert Aquin's cult novel, Trou de m?moire (in its English translation Blackout), first published in 1968, I try to illustrate this paradox and to emphasize the heuristic functions of memory blanks, gaps and lapses in certain postmodern narratives, after the historical breakdown of "the great narratives" (Lyotard). In this perspective, the example of Quebec, through the voice of one of its more gifted yet controversial novelist, can be seen as emblematic of what happens when the mnemonic impossibility of rewriting history opens up new possibilities for writing fiction.

Information types and display methods according to the relation between frequency of exposure and degree of cognition was suggested by this study as a way to enhance effective communication by information in aspect of user cognition. First of all, we ascertained the relation between frequency of exposure and degree of cognition by literature research for cognitive psychology and cognitive engineering psychology, results are as follows based in it. First, we suggested information types and attributes for visualization as 'Framework' which helps designers understand cognitive demands of users. Specifically, there are 4 types(STM, STA, LTM, LTA) of information according to the relation between frequency of exposure and degree of cognition, cognitive characteristics for each types and 'attributes matrix for visualization' which is consisted of 14 attributes of high -quality information and resorted by the types. Second, we suggested a guideline for display methods according to depth of information in the design process of information contents. For display methods of STM, STA information as primary information, we suggested "Attribution theory of Distinctiveness", "Advance Organizer", "Progress Closure", "Affordance", for display methods of LTM information as multidimensional information, we suggested "Modularity", "Consistency", "Mimicry", "Mnemonic Device". We had found from this study that there are distinction of status for attributes of information visualization according to information types or depth, and various display methods by them.

This study aims to consider the display method of the STA information that holds aesthetic cultural distinctiveness with the capability of immediate recognition of information in the relationship between the exposed time and the degree of cognition. As an consideration on the display method of information in an efficient way according as 'information attributes', the purpose of this study is to identify the visualization attributes of the STA information and to seek out display methods accordingly. Based on the information design and cognitive psychology, the cognitive features of the STA information have been identified and four visualization attributes of the STA information have been found based on the preceding studies on the information attributes in line with the relationship between exposure frequency and the level of awareness. In terms of information recognition, a metaphor, metonymy, use of indexical image and context, rhetoric, and Mnemonic have been proposed as major display methods for 'Understandable' and 'Conciseness', which are the major visualization attributes of the STA information while humor, parody, distinctiveness, friendliness, kitsch, formative beauty and newness have been suggested as the major display methods of 'Relevance' and 'Valuable', which are the major visualization attributes from the perspective of sensitive perception of information. Based on the results of this study, I'm planning to come up with display methods and to proceed with analyzing the relationship of the degree of cognition in association with context.
