Objectives : This survey was done in order to find out how Korean medical doctors derive pattern identification for acupuncture prescriptions in treating knee pain in real clinical practice. Methods : The survey questionnaire was developed by the committee of experts who major in acupuncture & moxibustion or statistics for acupuncture clinical trial protocol development. The questionnaires were distributed via e-mail to 75 members of Korean Acupuncture & moxibustion society from March 26th to April 14th in 2009. 57 members completed answers, and the computerized data were analyzed by SPSS 17.0 statistical program. Results : 1.54 Korean medical doctors selected meridian pattern identification based on the course of the meridians(52.5%), visceral pattern identification(27.1%), pattern identification based on cause of disease(8.5%) as the most commonly used pattern identification methods for acupuncture prescription when treating knee pain patients in real clinical practice. 2. In meridian pattern identification based on the course of the meridians, liver meridian of the medial knee region(13.2%), bladder meridian of the posterior knee region(12.0%), spleen meridian of the lateral knee region(11.7%), stomach meridian of the anterior knee region(9.8%) and kidney meridian of the medial knee region(8.6%) were selected. 3. In visceral pattern identification, blood stasis of sinews due to liver and kidney deficiency(5.3%), damp joint with yang deficiency of liver and kidney(4.9%), kidney qi deficiency with congealing cold(4.5%), yin deficiency of liver and kidney(4.1%) were selected. Conclusions : In our e-mail survey, Korean medical doctors answered that Meridian Pattern Identification based on the course of the meridians is the most often used diagnosis method. Visceral pattern identification, pattern identification based on cause of disease, pattern identification based on symptom and pattern identification based on qi-blood-yin-yang theory in order of frequency used, were selected for knee pain diagnosis in real clinical practice.

This paper present s a pattern generation scheme from financial charts. The patterns constitute knowledge which consists of patterns as the conditional part and the impact of the pattern as the conclusion part. The patterns in charts are represented in a syntactic approach. If the pattern elements and the impact of patterns are defined, the patterns are synthesized from simple to the more highly credible by evaluating each intermediate pattern from the instances. The overall process is divided into primitive discovery by Genetic Algorithms and pattern synthesis from the discovered primitives by the Syntactic Pattern-based Inductive Learning (SYNPLE) algorithm which we have developed. We have applied the scheme to a chart : the trend lines of stock price in daily base. The scheme can generate very credible patterns from training data sets.

능동위상배열안테나는 적절한 급전신호 가중치 선택에 따라 대국을 향해 주 빔을 조향할 수 있을 뿐만 아니라 간섭원 방향으로 패턴 널을 형성할 수 있다. 주 빔의 조향을 위한 급전신호 가중치는 방사소자의 위치를 기반으로 쉽게 산출할 수 있다. 그리고 패턴 널 형성을 위한 급전신호 가중치 또한 적절한 요구 방사패턴 설정과 WLSM(Weighted Least Squares Method)을 이용하면 산출할 수 있다. 그러나 일반적인 무선 통신망 환경에서 간섭원의 위치는 미인지 상황에 있다. 따라서 적응형 패턴 널 형성 기법이 필요하다. 본 논문에서는 요구 방사특성 설정에 따른 패턴 널 형성이 가능함을 확인하고, 이를 기반으로 관측 영역 기준 이진탐색 알고리즘을 이용하여 간섭원 적응형 패턴 널 형성 기법에 관하여 연구하였다. 제시된 기법을 기반으로 모의실험을 수행한 결과, 효율적으로 간섭 적응형 패턴 널 형성이 가능함을 확인하였다.

An efficient torso pattern has been developed to cope with the future trend of order-based, individualized production like the E.C.(Electronic Commerce) in the apparel industry, and to make a database foundation of automatic garment pattern drafting. For this purpose, a non-contact three-dimensional anthropometric measurement system was used to provide a lot of accurate body data for better individual fit, and an automatic pattern drafting system that can easily generate various size patterns and construct a pattern database has been developed too. The subjects of this research were 18 to 24 year-old women whose data had been gathered through the Korean national investigation of anthropometry for industrial standards in 1997 and various body shapes were analyzed by the measurements. And a special software system has been developed to verify the validity of newly proposed drawing rules. The results of sensory evaluation for appearance and moving fitness of the new torso pattern showed a significant improvement in individual fit even for the figures with large deviation from standard shape compared with the results of the traditional one.

In this paper, we design a perceptually invisible dot pattern layout and its recognition scheme, and we apply the recognition scheme into a smart self learning aid for interactive learning aid. To increase maximum information capacity and also increase robustness to the noises, we design a ECC (error correcting code) based dot pattern with directional vector indicator. To make a smart self-learning aid, we embed the micro dot pattern (20 information bit + 15 ECC bits + 9 layout information bit) using K ink (CMYK) and extract the dot pattern using IR (infrared) LED and IR filter based camera, which is embedded in the smart pen. The reason we use K ink is that K ink is a carbon based ink in nature, and carbon is easily recognized with IR even without light. After acquiring IR camera images for the dot patterns, we perform layout adjustment using the 9 layout information bit, and extract 20 information bits from 35 data bits which is composed of 20 information bits and 15 ECC bits. To embed and extract information bits, we use topology based dot pattern recognition scheme which is robust to geometric distortion which is very usual in camera based recognition scheme. Topology based pattern recognition traces next information bit symbols using topological distance measurement from the pivot information bit. We implemented and experimented with sample patterns, and it shows that we can achieve almost 99% recognition for our embedding patterns.

The purpose of this study is to link traditional patterns to mordern clothing. Of all the traditional patterns, the fish pattern was chosen for use during the development of a creative one-piece design for woman and shirts design for man. This study is based upon document searches, including research papers. Through these searches, it investigates the symbolic meaning, formation of the fish pattern and the creative design process. Based on this investigation, the study attempts to modernize the fish pattern and apply the fish patterns to the design of a one-piece dress and shirts. The design procedure includes three sub-processes: selection, arrangement and color-scheme. The selection process, the form of the pattern was edited using Adobe Photoshop. The arrangement of the pattern was made through the checklist conception method, containing the following functions: expand, reset, repeat, omission and dismantling. For the color-scheme of the pattern, Paul Klee(1879-1940)work was selected, and the colors in his work were adopted when dyeing the rest of the one-piece dress and shirts as well as fish features. In conclusion, six designs of the one-pieces dress and shirts were created by using one of Korea's traditional patterns-the fish pattern. This kind of study not only let the world know about the unique beauty of nations but also helps to inspire people who has a profession in design, by suggesting design development process based on design competitiveness improvement factor from fusion of tradition and modern.

DTN(Delay/Disruption Tolerant Network)에서 라우팅 프로토콜은 전송 지연 및 성공적인 전달 확률의 성능을 개선하기 위해 중요하다. 이 논문에서 우리는 이동성 유형 기반의 라우팅(MPR ; Mobility Pattern based Routing)이라는 효과적인 DTN 라우팅 알고리즘을 제안하는데 이는 이동 노드의 이동성 유형에 근거해 복사되는 메시지의 수를 제어하게 된다. 또한, 우리는 인간 이동성 유형을 가장 잘 나타낼 수 있는 확산성이 매우 큰(super-diffusive) 성질을 가지는 실제적인 "Levy Walk" 이동성 유형을 고려하였다. 우리는 제안된 MPR 알고리즘과 Levy Walk 이동성 유형의 검증을 위해 ONE simulator를 이용한 DTN simulator를 구현하였다. 시뮬레이션 결과 이동성 유형이 DTN 라우팅 성능의 정확한 분석을 위해 매우 중요하다는 것과 제안한 MPR이 실제 이동성 유형 하에서 성공적인 전달 확률이나 전송 지연 측면에서 라우팅 성능을 향상시킴을 보였다.
