This study is aimed to systematically grasp the visual and informative needs of sign system and secure the formativeness sample for standardization model. This study, therefore, will help building the requirements to create design value and secure objectiveness for realization of practical use of the communication design plan, and means transference of the external and internal information system of railroad vehicles for practical use into the standardization model. The pictorial sign based information delivery is a communication process and way gained through vision and perception, so that grasping the formative structure connoted in message is not less than understanding the characteristics of the essence. In this study, I defined the symbolic expressions inherent in TTX sign system to be perceptional action and value norms as general signatures and signifiers.

Historical books are records of information using text and images and is one of the valuable cultural heritages of mankind. However, these books wear, tear and are damaged with time, so we are restricted in our usage of them for study or research. There are many libraries and museums around the world researching a method to digitize the historical books to prevent their collection from damage. Digitizing the historical books not only produce digital images but also a valuable high quality digital information. Digitizing process also keeps the original content of the historical books as well as add a value as research material as a bibliographical, artistic and archaeological item. Furthermore, its information would be provided through a network, like internet, to share and to promote more advanced studies. The purpose of this study is to examine the principles and method of digitization of historical books. This study also researches the meaning and problems of digitizing process for more effective usage.

Big data analysis is the ability to collect, store, manage and analyze data from existing database management tools. Big data refers to large scale data that is generated in a digital environment, is large in size, has a short generation cycle, and includes not only numeric data but also text and image data. Big data is data that is difficult to manage and analyze in the conventional way. It has huge size, various types, fast generation and velocity. Therefore, companies in most industries are making efforts to create value through the application of Big data. In this study, we analyzed the meaning of keyword using Social Matrix, a big data analysis tool of Daum communications. Also, the theoretical implications are presented based on the analysis results.

This study identified the meaning of mathematical justification and its characteristics for middle school math gifted students. 17 middle school math gifted students participated in questionnaires and written exams. Results show that the gifted students recognized justification in various meanings such as proof, systematization, discovery, intellectual challenge of mathematical justification, and the preference for deductive justification. As a result of justification exams, there was a difference in algebra and geometry. While there were many deductive justifications in both algebra and geometry questionnaires, the difference exists in empirical justifications: there were many empirical justifications in algebra, but there were few in geometry questions. When deductive justification was completed, the students showed satisfaction with their own justification. However, they showed dissatisfaction when they could not deductively justify the generality of the proposition using mathematical symbols. From the results of the study, it was found that justification education that can improve algebraic translation ability is necessary so that gifted students can realize the limitations and usefulness of empirical reasoning and make deductive justification.

The public performance of drama has essence to convert text to visual images as stage and to represent, inform such visual images. Visual image is formed through a space as stage. Stage is a dish to fill the texts and is the mother's womb of visual image. Namely, visual image of drama equals space image. The purpose of this study is a trial to grasp the structure and system represented through interpreting. Especially, the concerns of this study are not semiology of letter imported in image but spacial image text importing just contents of text and the process and contents grasping the structure and meaning of dramatic space. Finally, this study proposed 'the system of space embodiment'from the semiotic point of view as interpretation methodology of actual memorial, symbolic space.

본 연구에서는 인간과 컴퓨터 사이의 음성을 이용한 대화 시스템을 구현하였다. 특별히 음성을 인식하는데 있어서 단어추출(word apotting) 방법을 사용하는 경우에 알맞은 의미 분석 방법과 도표 형태의 규칙을 기반으로 하여 시스템의 응답을 생성하는 방법에 대하여 연구하였다. 단어추출 방법을 사용하여 음성을 인식하는 경우에는 형태소분석 및 구문분석의 과정을 이용하여 사용자의 발화 의도를 분석하기 어려우므로 새로운 의미분석 방법을 필요로 한다. 본 연구에서는 퍼지 관계를 사용하여 사용자의 발화 의도를 파악하는 새로운 의미분석 방법을 제안하였다. 그리고, 사용자의 발화 의도에 적절한 시스템의 응답을 만들고 응답의 내용을 효율적으로 관리하기 위한 방범으로 현재의 상태와 사용자의 의도에 따른 응답 규칙을 만들었다. 이 규칙은 도표의 형태로 구현되어 규칙의 갱신 및 확장을 편리하게 만들었다. 대화의 영역은 열차 예매에 관련된 예매, 취소, 문의 및 관광지 안내로 제안하였다. 음성의 오인식에 의한 오류에 적절히 대처하기 위해 시스템의 응답은 확인 및 수정 과정을 포함하고 있다. 본 시스템은 문자 입력과 음성 입력으로 각각 실험한 결과, 사용자는 시스템의 도움을 받아 자신이 의도하는 목적을 달성할 수 있었다.

A concept hierarchy represents the knowledge with multi-level form, which is very useful to categorize, store and retrieve the data. Traditionally, a concept hierarchy has been built manually by domain experts. However, the manual construction of a concept hierarchy has caused many problems such as enormous development and maintenance costs and human errors such as inconsistency. This paper proposes the automatic creation of concept hierarchies using the predefined hypernym relation. To create the hierarchy automatically, we first eliminate the ambiguity of the senses of data values, and construct the hierarchy by grouping and leveling of the remaining senses. We use the WordNet explanations for multi-meaning word to eliminate the ambiguity and use the WordNet hypernym relations to create multi-level hierarchy structure.

One of the challenges of the digital forensics is how to handle certain amounts of data efficiently. Although reliable and various approximate matching algorithms have been presented to quickly identify similarities between digital objects, its practical effectiveness to identify the semantic similarity is low because of frequent false positives. To solve this problem, we suggest adding a pre-processing of the approximate matching target dataset to increase matching accuracy while maintaining the reliability of the approximate matching algorithm. To verify the effectiveness, we experimented with two datasets of eml and hwp using sdhash in order to identify the semantic similarity.

오늘날 영어교육은 교과과정령에 엄연히 명시된 네 가지 기능(four skills) 즉 듣기, 말하기, 원기, 쓰기라는 정당하고도 보편 타당성 있는 명분 하에 어떻게 가르쳐 왔는가 를 반문해 보면 많은 아쉬움이 남는다. 그간 6년간의 중등과정, 심지어는 대학에서 환 두해까지 영어를 이수한 사람틀 중에는 문자를 통해서는 상당한 수준, 그것도 영어 토박이들조차 놀랄 정도의 영어를 이해하지만, 소리를 통해 들을 때는 ---말하는 것은 두말 할 것도 없고---아주 간단한 내용의 영어조차 알아듣기 힘든 경험을 한 사람이 많다는 것은 부인할 수 없는 사실이다. 그 이유는 명백하다. 즉, 문자를 대할 때는 시각적 자극의 형태가 두뇌 속에 저장된 정보---가공할 문법적 지식---와 일치하기 때문에 쉽게 이해를 할 수 있는 반면, 소리를 들을 때는 청각적 자극의 형태가 두뇌 속에 저장된 정보---극히 불완전한 발음사전, 또는 모국어의 음운체계에 의한 영어발음--- 와 차이가 있기 때문일 것이다. 그러므로 적어도 말소리를 매체로 하는 의사소통에 있어서는 영어의 본토박이 발음을 정확히, 아니면 적어도 매우 근접하게 나마 터득하여(습관화하여)두뇌에 저장하는 일이 가장 중요한 일이다. 따라서 영어교사는 모국어의 음운체계에 대한 정확하고도 상세한 지식을 토대로 하여 영어의 음운체계와 '언어학적으로 의미 있는 (linguistically significant)' 대초분석의 방법으로 발음을 지도한다면 보다 나은 학습효과를 기대할 수 있을 것이다. 일반적으로 모국어의 발음이 외국어의 발음에 간섭을 유발하는 경우는 다음과 같다. 1. 분절음체계가 서로 다를 때 2. 한 언어의 음소가 다른 언어의 이음(allophone)일 때 3. 유사한 음의 조음장소와 방법 이 다를 때 4. 분절음의 분포 또는 배열이 다를 때 5. 음운현상이 다를 때 6. 언어의 리듬이 다를 때 위의 여섯 가지 경우를 중심으로 영어와 한국어의 발음특성을 대조하여 '낯선 말투(foreign accent)' 또는 발음오류를 최소로 줄이는 것이 영어교사의 일차적인 목표이다.

This study reviews various kinds of records filing systems, which function as a basic fundamental to effective records management. The purposes, methods and characteristics of Alphabetic, geographic, numeric, subject, and combined filing systems are examined. The alphabetic filing method uses letters of the alphabet to determine the order of names of people and companies. In subject filing the subjects are filed in alphabetic order. In numeric filing, numbers representing names or subjects are used. When records are requested by place or location rather than by individual or business name, geographic filing is advantageous.
