  • Document image is segmented and classified into text, picture, or table by a document layout analysis, and the words in table regions are significant for keyword spotting because they are more meaningful than the words in other regions. This paper proposes a method to extract words from table regions in document images. As word extraction from table regions is practically regarded extracting words from cell regions composing the table, it is necessary to extract the cell correctly. In the cell extraction module, table frame is extracted first by analyzing connected components, and then the intersection points are extracted from the table frame. We modify the false intersections using the correlation between the neighboring intersections, and extract the cells using the information of intersections. Text regions in the individual cells are located by using the connected components information that was obtained during the cell extraction module, and they are segmented into text lines by using projection profiles. Finally we divide the segmented lines into words using gap clustering and special symbol detection. The experiment performed on In table images that are extracted from Korean documents, and shows $99.16\%$ accuracy of word extraction.

  • In this paper, we propose the algorithm for generating the array of elemental image by using look-up table (L UT) in a computer generated integral imaging system. It makes the LUT independently for the projection point of x and y. The algorithm using LUT to the existing ones needs less computing time to generate the array of elemental image. By comparing the computing time of proposed algorithm with that of the existing algorithms e xperimently, we proved the efficiency of proposed algorithm.

  • 본 연구팀은 유비쿼터스 게임 플랫폼을 위한 Embedded C++ 컴파일러를 개발하였으며, 컴파일러 개발 과정에서 객체지향언어인 C++과 Java 언어를 모두 수용할 수 있는 심벌 테이블을 설계하였다. 심벌 테이블은 컴파일러의 어휘 분석과 구문 분석 과정을 거친 후 SDT(syntax-directed translation)에 의해 생성된 AST(Abstract Syntax Tree)를 분석하여 인식된 명칭(identifier)과 그 속성(attribute)들을 수집하여 저장하는 자료구조로써, 심벌 테이블에 저장된 속성들은 의미 분석(semantic analysis) 단계에서 수집된 속성과 참조된 명칭의 사용이 타당한지를 검사하고, 코드 생성(code generation) 단계에서 올바른 코드가 생성되도록 하는 중요한 요소이다. 따라서 심벌 테이블의 설계가 올바른지와 입력된 속성이 정확한지에 대한 검증과 분석은 필수 불가결하다. 본 논문에서는 컴파일러 개발과정에서 설계한 심벌 테이블을 검증하고 분석하기 위한 목적으로써 심벌 테이블을 이용하여 선언문을 복원시키는 역번역기(detranslator)에 대하여 기술한다. 구현된 역번역기는 C++ 컴파일러와 Java 컴파일러의 선언문 처리 과정에서 심벌 테이블에 입력된 속성들을 본래의 입력 프로그램으로 역번역한다. 따라서 역번역기를 통하여 심벌 테이블의 완전성과 심벌 테이블에 입력된 속성 정보의 정확성을 쉽게 검증할 수 있으며, 역번역과 함께 출력되는 디버그 정보를 이용하여 효율적으로 컴파일러의 개발과 수정을 할 수 있다.

  • This study has showed verified results on 'Survey into Observer Preference for Table Decoration for Eating and Drinking'. It is a preliminary study to look into interrelation of preference to color tables, image adjectives, aesthetic value, by giving color changes in a certain regularity to each influential factor in functional table decoration. The result has demonstrated that, as for color image and preference,'observers prefers mid/low dark-toned brown which gives a feeling of 'high-quality, and like to eat', and orange tone with a fooling of 'warm and colorful'. In evaluating interrelation between preference and aesthetic value, the study has revealed that ordinary people take the influential factor of 'unity and Gestalt' seriously, while non-professionals preferred 'uniqueness'. Stimulant No. 7 is one of constituent factors of functional table decoration, eliciting significance of images on colors ant aesthetic value. This study also has practical problems about insufficiency or inadequateness in producing mood suitable to T P O, according to depending upon color changes in picking up stimulants, or other problems in selecting stimulants, according to time, seasons and generational parameter in which the inquiry is conducted, but it will serve as a stepping stone for developing new design using both qualitative and quantitative data in 려nctional table decoration.

  • Well-set tabletops influence customers' purchase behavior or post-purchase behavior by making the quality and image of a restaurant distinguished and customers impressed. This study aims to investigate the relations between the perception of environment among physical environments of restaurants and psychological responses to their tabletops and consumers' attitudes in order to suggest new guidelines for table-setting. As a result, the direct relations between the perception of environment in the tabletops of the restaurants and consumers' behavioral intention indicated that the perception factors of tabletops affected consumer behavior and that these perception factors affected the formation of general attitudes among consumers through emotional and cognitive responses. This result shows that tabletops can be an important key in managing restaurants with changing customer needs. Therefore, it is expected that positive customer attitude can be made by provoking their psychological responses with unique and attractive tabletop settings.

  • It is very important to track whether software is properly developed according to requirements. This study suggests a method to track requirements by using a tracking table. In this study, the tracking table indicates why such requirements are included by detailing the content of requests for proposals and proposals. The table also facilitates verification of the consistency between outputs and the integrity by having ID codes of each requirement mapped to each output. Furthermore, as this study was conducted, it was found that some factors were required to be added or supplemented to the outputs at the requirement gathering stage of MaRMI-Ⅲ v.4.0 methodology. Thus, this study seeks to present this additional result along with the enhanced tracking table. By verifying outputs, the tracking table presented in this study will help to reduce all kinds of risks and problems that may occur in software development due to the lack of management of requirements. In addition, the output of the requirement-gathering stage of MaRMI-Ⅲ v.4.0 methodology will be improved/supplemented according to the creation of tracking tables; this will increment the applicability of the MaRMI-III methodology.

  • There are various methods to trace output in software development to verify the consistency and completeness of requirements. Existing studies do present the trace meta-model or automated tools, but fail to list specifically traced output or traced items. Also, in regards to trace tables, which contain traced items, existing studies don‘t consider the whole software development process but merely its sub-process. Given this, the present study suggests an extended requirements tracetable that tracks output from the inception of the project through the architectural design phase to the application delivery, following up on the researcher’s previous study on a tracetable that considered only a sub-process of the whole development process. In addition, in order to address the problem of the tracking process becoming complicated with increased tracefields due to an extended trace table, the researcher suggests a method for normalizing a requirements tracetable that can integrate and separate by development process phase. Apply it to theH system development project of a D company, and this study caseverified application possibility of study, confirmed an effect of a chase to easily find out an error of requirements. Improve precision of a traceto verify consistency of requirements and completeness through this study, and will minimize failure of a software development.
