A graphic control language using function block diagram approach is designed and implemented, applicable to real-time control for continuous process automation system. The procedure implementing the control language is composed of three parts, editor, compiler, and executer. The editor generates the control algorithm file, which contains function block information in the text form, by menu-driven method on the color graphic screen. The compiler translates the contents of the control algorithm file to machine codes and their related data. Then, the executer generates a task that makes the machine codes executed at every sampling period in the target processor. The validity of the concept in its design and implementaion is assured by on-line simulation in the multi-function controller designed for continuous process automation.

The purpose of this study is to compare and analyze the aspects of task-based materials in high school English textbooks for first year students in Korea. Based on the theoretical backgrounds for designing communicative tasks and the basic contents of the 7th national curriculum for English, a total of six different qualitative evaluation categories of task-based materials are constructed. The six categories include input data, settings, activity types, language skills, activity themes, and communicative functions. The results of the data analysis showed that the regulations of the 7th national English curriculum, which were aimed at improving the students' communicative abilities, were properly reflected in the materials of task-based activities of all textbooks. On the other hand, a few problems were found in some textbooks: too many individual tasks; being out of proportion in presenting task types and themes; non-systematic introduction of language skills, etc. To conclude, a few suggestions are made to provide some meaningful considerations for the text material developers in order to produce better textbooks in the future: task goals and rationale that encourage the learner's positive motivation; authenticity of input data based on the real-world context; a collaborative learning environment that enhances communicative interaction; a proportional representation of the various activity types including creative problem-solving procedures; systematic introduction of integrated language skills, etc.

With the advance of the Internet and computing technologies, e-learning is now a hot issue worldwide for providing the effective learning on the cyber-space. However, most of existing e-learning contents have been developed mainly based on text, including simple multimedia elements such as images, animations, and voices. This paper suggests a method effective for the computer programming e-learning. The method is based on program visualization using flowcharts. It features the stepwise hierarchical program visualization on the level of statements, the flowchart based visualization for control constructs of languages, visualization over whole programs, visualization compared with source codes, and interaction with users. Finally, we implement a system to realize the suggested method, and execute it for an example program.

There are so many kind of a control program that is applied in various process fields such as power generation plant, water treatment plant, incinerator plant, chemical plant, cement plant etc.. Because an engineer in field edits and changes and debugs and tests properly control programs using text-based control language, it is very hard for the him to apply to plant. Therefore, this research implemented a graphical tool for control program builder that is applicable to various plants and usable engineers having a little knowledge for control language. I wish to run more efficiently precision process control offering function that can see visual expression about flow of control signal and intermediate output values of control program displayed in screen using this implemented function block builder.

This paper presents GrammE, a grammar development environment for feature-based APSG. At the stage of a grammar development, analysis are be done by interpreting the grammar under development, given in a text format, it is relatively easy to diagnose the grammar. Once developed, the grammar is compiled, by using the embedded grammar compiler, into a parser program written in $C^{++}$. The parser program can be used in various types of natural language processing systems requiring syntactic analysis. GrammE is language-independent, and so far has been used for the development of Korean and Chinese grammars.

본 논문에서는 Deway order기법을 이용하여 관계형 데이터베이스 환경에서 효율적으로 XML 문서를 저장, 검색, 결과값을 반환하기 위한 XQuery 질의 처리기를 설계하고 구현한다. 우선 첫 번째로 dewey order기법을 이용하여 XML문서를 저장하기 위한 색인 모델을 관계형 데이터 베이스에 설계하고 XML문서를 저장한다. 두 번째로 이를 기반으로 XML 전문검색 언어인 XPath식을 SQL로 변환하는 전체적인 알고리즘을 제시한다. 세 번째로 위에서 변환된 SQL문의 질의 결과값을 처 음에 저장될 당시의 XML문서의 형태와 Text를 그대로 유지하면서 사용자에게 반환하는 알고리즘을 제시한다. 이 부분은 기존의 발표된 논문에서는 좀처럼 보기 드문 내용으로 XQuery에 포함되는 다양 한 형태의 Xpath식을 SQL문으로 변환할 수 있는 정확한 방법 뿐만 아니라 각각 한번의 질의로 얻고 하는 엘리먼트들과 어트리뷰트들을 찾아 XML문서 그대로 출력하는 방법에 초점을 두어 본 논문을 기 술한다. 마지막으로 이를 실제로 구현하고 Test한 결과를 바탕으로 Dewey order기법을 이용하여 XML 색인 모델을 설계 할 경우 SQL문으로 변환하여 질의를 처리하는 측면에서나 질의한 결과값을 XML문서 형태로 반환하는 측면에서나 이 기법을 사용하지 않는 Local order방식보다 성능이 훨씬 우수하다라는 결론을 제시한다.

HANTEC1.0은 12만 건의 문서집합과 30개의 질의집합, 그리고 각 질의에 대한 적합문서로 구성된 정보검색용 한글 테스트 컬렉션이다. 본 연구에서는 HANTEC1.0의 확장 및 보완하기 위해 과학기술분야 20개의 질의를 추가하였는데, 질의 추가를 위해서 일본 NACSIS 테스트 컬렉션의 질의를 번역하여 사용함으로써 한일 교차언어 검색환경을 조성하고자 하였다. 추가된 각 질의에 대해서는 여러 검색기에서 총 41가지 검색방법으로 검색한 후, 각 검색조합의 상위 50개 문서로 구성된 중간 결과집합을 만들었으며, 이를 대상으로 적합성판정에 대한 평가기준 및 절차 교육이 이루어진 평가자가 각 질의에 대한 적합성평가를 실시하였다. 이렇게 구축된 HANTEC 테스트 컬렉션의 적합문서 집합의 객관적 품질 평가와 시스템 성능평가를 위하여 통계적인 방법을 적용하므로써 공신력있고 일반화된 테스트 컬렉션을 구축하고자 하였다. 현재 HANTEC2.0은 검색분야 연구자 및 개발자에게 자유롭게 배포 중이며 정복머색 시스템의 신뢰도 측정을 목적으로 하는 학술대회의 연구결과 발표 및 제품 비교 등에 활용되어질 것이다.

This study explores reading fluency among elementary school students considering language level and family income(low SES). Forty eight students from 1st to 3rd grades participated in two paragraph reading tasks. Half of the children were from low income family and half of the children had low lexical knowledge. Reading fluency as in the number of correctly read syllables per minute, the total error frequency and error types were used to compare group differences. There were significant differences in the number of correctly read syllables per minute between two income groups and two language groups. There was a significant difference between low income group and non-low income group in total number of errors only when children's lexical knowledge were low. There were no group differences in error types of repetition and omission. Substitution and insertion error seemed to reflect the total error pattern. These results imply the importance of early screening and early involvement for children with low lexical knowledge from low income family. Monitoring and early intervention will support these children's reading development.

The proliferation of the Internet grows, according to electronic documents, along with increasing importance of technology in information retrieval. This research is possible to build a more efficient and accurate knowledge-base with unstructured text documents from the Web using to extract knowledge of the core meaning of LGG (Local Grammar Graph). We have built a ontology based on OWL(Web Ontology Language) using the areas of particular stocks up/down patterns created by the extraction and grammar patterns. It is possible for the user can search for meaning and quality of information about the user wants.

Big datatics technology that can store and analyze data and obtain new knowledge has been adjusted for importance in many fields of the society. Big data is emerging as an important problem in the field of information and communication technology, but the mind of continuous technology is rising. R, a tool that can analyze big data, is a language and environment that enables information analysis of statistical bases. In this thesis, we use this to analyze the Bible data. R is used to investigate the frequency of what text is distributed and analyze the Bible through analysis of social network.
