형태학적 필터를 영상 처리 시스템에 효율적으로 구현하기 위하여서는 영상 처리 시스템의 구조적인 제약으로 인하여 형태소의 크기가 작아야 하며, 따라서 크기가 큰 형태소를 가지는 필터의 구현을 위하여 주어진 형태소를 작은 크기의 형태소로 분해하는 과정이 필요하다. 본 논문에서는 임의의 형태학적 필터를 3$\times$3 Pipeline Machine에 효율적으로 구현하기 위하여 모양과 크기에 아무 제한 없이 행태소를 분해하는 알고리즘을 개발한다. 먼저 주어진 형태소를 순차적 방법으로 합집합 분해하고, 각 분해된 결과를 다시 3$\times$3 크기의 형태소로 최적 분해하여 최종 형태소 분해 결과를 얻는다. 개발된 분해 알고리즘을 형태소에 적용하여 분해 결과를 구하였으며, 최적에 매우 근접한 결과를 얻을 수 있었다.

We will introduce a new web-based knowledge management system in progress, in which XML-based web information extraction and our structuring knowledge technologies are combined using ontology-based natural language processing. Our aim is to provide efficient access to heterogeneous information on the web, enabling users to use a wide range of textual and non textual resources, such as newspapers and databases, effortlessly to accelerate knowledge acquisition from such knowledge sources. In order to achieve the efficient knowledge management, we propose at first an XML-based Web information extraction which contains a sophisticated control language to extract data from Web pages. With using standard XML Technologies in the system, our approach can make extracting information easy because of a) detaching rules from processing, b) restricting target for processing, c) Interactive operations for developing extracting rules. Then we propose a structuring knowledge system which includes, 1) automatic term recognition, 2) domain oriented automatic term clustering, 3) similarity-based document retrieval, 4) real-time document clustering, and 5) visualization. The system supports integrating different types of databases (textual and non textual) and retrieving different types of information simultaneously. Through further explanation to the specification and the implementation technique of the system, we will demonstrate how the system can accelerate knowledge acquisition on the Web even for novice users of the field.

When we design real-time software target system is analyzed and then we structure sequential executive modules into concurrent tasks. As a result of the analysis, control flow and dataflow diagram based on the RTSA notation is produced. This diagram is structured into concurrenttasks under the condition that performance problem is not serious. The criteria structuring concurrenttasks are introduced as Concurrent Design Approach for Real-Time System(CODARTS) by Gomaa.But structuring concurrent tasks using the criteria of CODARTS is somewhat difficult because thecriteria are dependent on designer's experience. CODARTS is an wide-range and abstractmethodology. As a result, the design can be inconsistent and peoples can understand it differently Inthis paper, we restructure the CODARTS methodology, propose a revised CODARTS structure andrepresent the task structuring steps for this new framework to overcome the understanding andinconsistency problems. The revised CODARTS framework and task structuring steps can be used toautomate the design of real time concurrent software systems. Finally, we show an example of taskstructuring in revised CODARTS framework.

본 논문에서는 문자 검출 및 인식 기술을 활용하여 비정형의 폐 기능 검사지 이미지로부터 연구를 위한 관련 정보들을 추출하여 정형화하는 방법을 제안한다. 또한 문자 인식 오차율을 줄이기 위한 후처리 방법 또한 개발하고자 한다. 제안하는 정형화 방법은 폐 기능 검사지 이미지에 대해 문자 검출 모델을 사용해 검사지 내에 존재하는 모든 문자를 검출하고, 검출된 문자 이미지를 문자 인식 모델에 통과시켜 문자열을 얻어낸다. 얻어낸 문자열에 대해 문자열 매칭을 이용한 유효성 검토를 진행하고 정형화를 마무리한다. 제안하는 정형화 시스템의 오차율은 약 1% 이내, 검사지 당 처리속도는 2초 이내로 전문인력의 수작업을 통한 정형화 방법보다 더 효율적이고 안정적인 방식이라는 것을 확인할 수 있다.

Real-time(RT) object-oriented(OO) distributed computing is a form of RT distributed computing realized with a distributed computer system structured in the form of an object network. Several approached proposed in recent years for extending the conventional object structuring scheme to suit RT applications, are briefly reviewed. Then the approach named the TMO(Time-triggered Message-triggered Object)structuring scheme was formulated with the goal of instigating a quantum productivity jump in the design of distributed time triggered simulation. The TMO scheme is intended to facilitate the pursuit of a new paradigm in designing distributed time triggered simulation which is to realize real-time computing with a common and general design style that does not alienate the main-stream computing industry and yet to allow system engineers to confidently produce certifiable distributed time tiggered simulation for safety-critical applications. The TMO structuring scheme is a syntactically simple but semantically powerful extension of the conventional object structuring approached and as such, its support tools can be based on various well-established OO programming languages such as C＋＋ and on ubiquitous commercial RT operating system kernels. The Scheme enables a great reduction of the designers efforts in guaranteeing timely service capabilities of application systems.

The purpose of the study is to develop an integrated knowledge structuring system for the domain of engineering, in which ontology-based literature mining, knowledge acquisition, knowledge integration, and knowledge retrieval are combined using XML-based tag information and ontology management. The system supports combining different types of databases (papers and patents, technologies and innovations) and retrieving different types of knowledge simultaneously. The main objective of the system is to facilitate knowledge acquisition and knowledge retrieval from documents through an ontology-based dynamic similarity calculation and a visualization of automatically structured knowledge. Through experimentations we conducted using 100,000 words economic documents reported in the "Go！ Japan" project for analyzing Japanese industrial situation, and 100,000 words molecular biology Papers, we show the system is Practical enough for accelerating knowledge acquisition and knowledge discovery from the information sea.
