Combinational automatic test pattern generators (CATPG) have already been commercialized because their algorithms are well known and practical, while sequential automatic test pattern generators(SATPG) have been regarded as impractical because they are computationally complex. A technique to use CATPG instead of SATPG for test generation of sequential circuits is proposed. Redesign of seauential circuits such as Level Sensitive Scan Design (LSSD) is inevitable to use CATPG. Various partial scan techniques has been proposed to avoid full scan such as LSSD. It ha sbeen reported that SATPG is required to use partial scan techniques. We propose a technique to use CATPG for a new partial scan technique, and propose a new CATPG algorithm for the partially scanned circuits. The partial scan technique can be another choice of design for testability because it is computationally advantageous.

토지는 인간과 자연의 조형물로서 토지의 이용은 한 지역의 산업의 구조, 주거지의 형태, 에너지의 이용 유형 등을 결정짓는 주요 요소가 되었다. 그리고 토지 이용 연구는 한 지역의 성장 발전 과정을 측정하는 바로미터가 되기도 한다. 본 연구에서는 수도권 지역의 1950년에서 1990년까지 토지 이용 변화가 어렵게 변화하고 있는가를 분석하고자 한다. 토지 이용은 농촌용 토지와 도시용 토지로 나누고 토지 이용에 영향을 미친 독립변수로 도시화, 인구의 증가, 교통의 발달, 공업화, 토지 정책 등을 가정하였다. 농촌용 토지는 인구의 증가와 밀접한 관계가 있으며, 도시용 토지는 인구의 증가, 교통의 발달과 관계가 깊다. 농촌용 토지는 서울 북부 지방에서 탁월하고 도시용 토지는 서울 남부 지역이 탁월하다.

Objectives : The authors performed this study to further understand Saam acupuncture treatment in an aspect of the use of two patterns i.e. fixed- and transformed-pattern. Methods : The authors did documentary survey based on Do Hae Kyo Kam Sa Am Do In Chim Beop. 1. We investigated the frequency of the use of fixed- and transformed-pattern as well as the examples of use. 2. We surveyed related literatures and classified transformed-pattern. We did study on the principles of prescriptions of fixed- and transformed-pattern and researched the utilization. Results and Conclusions : 1. Fixed-pattern occupys 35.3% and transformed-pattern takes much more part. 2. Fixed-pattern is based on Nangyoung 69nan, and has the prescription of two enhancement and two inhibition by adaptation of Sangsaengsanggeuk(相生相剋) into self meridian and other meridian, and suggests the importance of the order of needling. 3. There are main points and assistant points in tonifying and suppressing of Fixed-pattern, accordingly, it has a system like Gunshinjwasa(君臣佐使). 4. Transformed-pattern is classified into following 3 types: first, the use of Nangyoung 75nan; second, the substitution of Junghuyl(井穴) with Hyunghyul(滎穴) or Haphyul(合穴) according to Nangyoung 73nan; third, the substitution of the same Osuhyul(五輸穴) in other meridians.

We proposed new light guide panel (LGP) fabrication method exploiting laser-processed inner scatterers and surface pattern. The proposed method has achieved LGP performance improvement in both brightness and uniformity. The inner scatterers and surface pattern of grid type were fabricated with a 2nd harmonic Nd:YAG pulse laser engraving system and a $CO_2$ laser scanning system, respectively. In the implementation of LGP, inner scatterers was arranged in accordance with linear or curved pattern with changing density and surface pattern was engraved on the surface of an inner-scatterers embedded LGP. The increase of scatterers' density and the use of surface patterns in both linear and curved pattern provided high luminance and uniformity enhancement. While thecurved pattern incorporated with increased scatterers' density and surface patterns yielded brightness improvement with preserving good uniformity, the linear pattern showed highly localized brightness near the light entrance of the LGP. We can also observe that the uniformity was mainly determined by pattern of inner scatterers, and the brightness was improved by the higher density and the utilization of surface patterns. From the results, the use of laser-processed inner and surface patterns can be a potential alternative for efficient and simple LGP fabrication method.

초음파센서는 저렴성, 단순한 구조, 기계적 강인성, 사용상의 적은 제약 등의 이점 때문에 다양한 응용분야에 적용된다. 물체의 인식에 초음파센서를 사용하기에는 낮은 분해능을 초래하는 불량한 방향성과 측정오류를 유발하는 반사성의 어려움을 내재하고 있다. 이런 문제를 개선하기 위해서 다양한 센서의 배열형태에서 많은 수의 센서를 사용하거나, 일정 수의 센서를 사용할 경우에는 센서의 배열을 기계적으로 이동시킨다. 본 논문에서는 물체의 패턴인식에 있어서 가장 기본적인 거리, 물체크기, 물체각도 값을 얻기 위해 간단하게 구성된 전자회로를 부가하여 초음파센서의 송출전압을 여러 단계로 변경시켜 얻어낸 데이터에 뉴로퍼지 기반의 지능적 계산 알고리즘을 적용하여 개선된 결과를 얻는다.

최근에 객체지향 소프트웨어를 설계하거나 구현방법으로 EJB 기반의 소프트웨어 개발이 많이 이용되고 있다. 일반적으로 EJB 기반 어플리케이션에서는 데이터베이스를 이용한 영속적인 데이터를 사용하는 경우가 대부분이다. 본 논문에서는 서버 측 작성 프로그램 중 엔티티빈 클래스에서 담당하는 데이터베이스 엑세스에 관련된 부분을 J2EE의 DAO 패턴을 이용하여 클래스를 각각 분리하였다. 이는 기존의 패턴 방법과는 큰 차이는 없으나, 동일 패턴내의 공통의 클래스들을 합성이 가능하도록 설계하였다. 그리고 생성된 각각의 DBMS 클래스들은 다른 엔티티빈 클래스에서도 사용이 가능하게 할 뿐만 아니라 여러 DBMS 환경에서도 Data Source를 추가적인 프로그램의 변경이나 작성 없이 연동이 가능하도록 하고 있다.

다양한 특징들을 광학적으로 병렬추출하여 패턴인식을 수행하는 시스템을 제안하고 실험하였다. 추출하려는 특징은 6개의 방향선소들 및 선소특징만으로 구별되지 않는 패턴들에 대한 공분산행렬의 고유벡터들이다. 이 시스템은 크게 특징추출부와 패턴인식부로 구성된다. 전자는 여러 특징을 병렬적으로 추출하기 위해 다중 Vander Lugt 필터를 사용하여 광학적으로 구현되었으며, 후자는 이들 추출된 특징들을 사용하여 패턴인식이 수행되도록 컴퓨터에서 구현되었다. 패턴인식 방법으로는, 추출된 특징을 인공신경망에 학습을 시키는 방법과 단순히 선소들의 논리적인 개수를 사용하는 방법, 두 가지가 각각 사용되었다. 여기서는 선소들로만 구성된 15개의 영문자 패턴들에 대해 실험하였고 그 실험결과를 보고한다.

Quickly picking up some valuable information from massive manufacturing event stream usually faces with the problem of long detection time, high memory consumption and low detection efficiency due to its stream characteristics of large volume, high velocity, many variety and small value. Aiming to solve the problem above for the current complex event processing methods because of not sharing detection during the detecting process for massive manufacturing event streams, an efficient complex event processing method based on multipattern sharing is presented in this paper. The achievement of this paper lies that a multipattern sharing technology is successfully used to realize the quick detection of complex event for massive manufacturing event streams. Specially, in our scheme, we firstly use pattern sharing technology to merge all the same prefix, suffix, or subpattern that existed in single pattern complex event detection models into a multiple pattern complex event detection model, then we use the new detection model to realize the quick detection for complex events from massive manufacturing event streams, as a result, our scheme can effectively solve the problems above by reducing lots of redundant building, storing, searching and calculating operations with pattern sharing technology. At the end of this paper, we use some simulation experiments to prove that our proposed multiple pattern processing scheme outperforms some general processing methods in current as a whole.

A fast pattern classification algorithm with Cellular Nonlinear Network-based dynamic programming is proposed. The Cellular Nonlinear Networks is an analog parallel processing architecture and the dynamic programing is an efficient computation algorithm for optimization problem. Combining merits of these two technologies, fast pattern classification with optimization is formed. On such CNN-based dynamic programming, if exemplars and test patterns are presented as the goals and the start positions, respectively, the optimal paths from test patterns to their closest exemplars are found. Such paths are utilized as aggregating keys for the classification. The algorithm is similar to the conventional neural network-based method in the use of the exemplar patterns but quite different in the use of the most likely path finding of the dynamic programming. The pattern classification is performed well regardless of degree of the nonlinearity in class borders.

The Clustering is representative method of components classification. The previous clustering methods that use cohesion and coupling cannot be effective because design pattern has focused on relation between classes. In this paper, we classified design patterns with features of object-oriented relationship. The result is that classification by clustering showed higher precision than classification by facet. It is effective that design patterns are classified by automatic clustering algorithm. When patterns are retrieved in classification of design patterns, we can use to compare them because similar pattern is saved to same category. Also we can manage repository efficiently because of storing patterns with link information.
