양재동,김양범(Jae-Dong Yang),Yang-Beom Kim 한국정보과학회 1997 정보과학회논문지(B) Vol.24 No.9

Rule-based expert system shells have one important drawback in handling uncertain knowledge. It is the drawback that the style of their fuzzy reasoning process and their semantics both are not compatible with those of relational databases. On the other hand, production rule-based languages whose structure is similar to that of the databases fail to possess the fuzzy reasoning ability. Proposed in this paper is a framework to support a semantic based inexact match with Fuzzy Match Predicate (F_MP). In a uniform way it allows matches including fuzzy linguistic variables as well as fuzzy numbers. Our framework also adopts a design alternative to conform not only the semantics of its knowledge representation but also its reasoning style to those of the relational framework. It is a natural consequence that such a design alternative entails a seamless integration of our work into the relational databases. Major advantage of our framework is that it can be implemented on top of the production rule-based languages without modifying their discrimination networks. That is mainly due to the minimal semantic gap bet ween the framework and the languages. In this paper, we demonstrate that 1) F_MP is a uniform framework to provide the rule-based languages with fuzzy match facilities semantically enhanced and that 2) its semantic conforms well to that of the relational one. 규칙 기반 전문가 시스템 쉘들은 불확실한 지식을 처리할 때, 퍼지 추론 방식과 시멘틱이 관계 데이타베이스 모델과 호환성이 없다는 중요한 결점을 가지고 있다. 반면에, 관계 데이타베이스와 구조가 유사한 생성 규칙 기반 언어들은 퍼지 추론 기능을 제공하지 못한다. 본 논문에서는 의미 기반 근사 부합을 지원하는 퍼지 부합 술어(Fuzzy Match Predicate, F_MP) 구조를 제안한다. 이 구조는 퍼지 숫자(fuzzy number)뿐 아니라 퍼지 언어 변수(fuzzy linguistic variable)도 하나의 일관된 방식으로 부합시킬 수 있는 것이 큰 특징이다. 또한, 이 구조는 관계형 틀에 지식 표현의 의미뿐만 아니라 추론의 방식들도 일치하도록 설계되었기 때문에, 무리 없이 관계 데이타베이스와 병합될 수 있다. 이 구조의 주된 장점은 생성 규칙 기반 언어들과 의미적으로 거의 차이가 없기 때문에, 분리망(discrimination network)을 수정하지 않고도 이들 위에서 바로 구현될 수 있다는 점이다. 본 논문에서는 1) F_MP가 규칙 기반 언어들에게 의미적으로 강화된 퍼지 부합 능력을 제공하는 일관성 있는 틀임을 보이고, 2) F_MP가 관계형 구조와도 잘 융화될 수 있음을 보인다.

불확정적으로 색인된 이미지 데이타베이스를 개념 기반으로 검색하기 위한 자료형

양재동 한국정보과학회 2002 정보과학회논문지 : 데이타베이스 Vol. No.

There are two significant drawbacks in triple image indexing; one is that it cannot support concept-based image retrieval and the other is that it fails to allow disjunctive labeling of images. To remedy the drawbacks, we propose a new technique supporting a concept-based retrieval against images indexed by indefinite fuzzy triples (I- fuzzy triples). The I-fuzzy triples allow not only a disjunctive image labeling , but also a concept-based matching against images labeled disjunctively. The disjunctive labeling is based on the expended closed world assumption and the concept-based image retrieval is based on fuzzy matching. In this paper, we also propose a concept-based query evaluation against the image database to extract desired answers with the degree of certaintyalpha in 트리플 이미지 색인 기법에는 두 가지 문제점이 있는 데 그 하나는 개념기반 이미지 검색을 지원하지 않는다는 것이고 다른 하나는 이접 레이블링 (labeling)이 허용되지 않는다는 점이다. 이 문제점들을 해결하기 위해서 본 논문에서는 불확정적 퍼지 트리플 (I- 퍼지 트리플)이라는 새로운 이미지 색인 자료 형을 제안한다. I-퍼지 트리플에 의한 이미지 색인 방식에서는 이접 레이블링을 허용하기 때문에, 이미지 내 객체들이 꼭 확정적으로 인식될 필요가 없으며, 또 확정적으로 인식되지 않는 이미지들에 대해서도 개념 기반 이미지 정합이 가능하다. 본 논문에서 제안하는 이접 레이블링은 확장된 폐 세계 가정에 기반을 두고 있으며, 개념 기반 이미지 검색은 퍼지 술어에 의한 정합에 근거를 두고 있다. 본 논문에서는 또한 이접 레이블링에 의해 불확정적으로 색인된 이미지 데이타베이스로부터 원하는 답을alpha in

Soft-Decision-and-Forward Protocol for Cooperative Communication Networks with Multiple Antennas

양재동,송경영,노종선,신동준 한국통신학회 2011 Journal of communications and networks Vol.13 No.3

In this paper, a cooperative relaying protocol called soft-decision-and-forward (SDF) with multiple antennas in each node is introduced. SDF protocol exploits the soft decision source symbol values from the received signal at the relay node. For orthogonal transmission (OT), orthogonal codes including Alamouti code are used and for non-orthogonal transmission (NT), distributed space-time codes are designed by using a quasi-orthogonal space-time block code. The optimal maximum likelihood (ML) decoders for the proposed protocolwith low decoding complexity are proposed. For OT, the ML decoders are derived as symbolwise decoders while for NT, the ML decoders are derived as pairwise decoders. It can be seen through simulations that SDF protocol outperforms AF protocol for both OT and NT.

物價變動會計의 適用에 관한 硏究 : 修正現在原價會計의 內容分析을 中心으로 A content Analysis in Reference to Intergration of Current Cost Accounting and General Prices Level Accounting

梁在東 단국대학교 대학원 1982 學術論叢 Vol.6 No.-

Financial statement drawn up according to the conventional cost accounting has been widely supported by every field in its objectivity and possibility of inspection evidence. But value of monetary under the circumstances those days on which price level is constantly increasing, has been gradually decreased, until purchasing power of monetary has also been decreased, and this results in the loss of the same attribute to values of monetary, and financial statement drawn up by current cost accounting to the user. As an accounting system to cope with inflation, general prices level accounting and current cost accounting has been advocated. In case of general price level accounting a) the comparison of financial ispossible b) the upkeep for real capital is possible c) the profit and loss of purchasing power is recognized, but as to the opinion of a) the choice cf price index. b) the character of the profit and loss for moneterial purchasing power are not agreed on yet. The object of current cost accounting is not transforming the standard value asset (expenses) from that of conventional cost in to that of current cost, and moreover, it seperates profits into operating profit and holding gains, but it becomes difficult to decide what current cost itself is. As the result of this, in holding gains, especially unrealized gains, there are many opinions about how to treat hish problem. For the purpose of aiding the limitation mutually that general price level accounting and current cost accounting are forced to grasp only a partial aspect of current cost, we consider to try the integration of both accounting systems. for which FASB's FAS 33 has been advocated. In this system, integratnio of current cost accounting and general price level accounting has the merits of its own and clarified as followings through the study of research examples: a) existing purchasing power as for unit of measurement b) current cost level as or standard of value c) accounting system adopting the conception of real capital as for the conception of capita. And general price level accounting has objections of a) understanding of profit and loss from purchasing power b) maintaining of real capital and current cost accounting has also been clarified as follows: a) the split-calculation between operating profit and holding gains b) the disclosure of financial condition having been reflected in the specified price as of term-end. A case-study revealed that above-stated two objectives can be realized simultaneously through a single financial statement. As a conclusion of this article, in spite of the consideration of all those aspects, we meet upon present both an applicational point of view and its means of settlement which are now at issue: a) It is more practical to choose indexation through the specified price index as a way of evaluation standard for the asset (expenses) b) It is more reasonable to choose CPI for the general price index to be measurement standard. c) For the supporting of invested monetary capital, it is not only required to support real capita, but also required to exclude (except) holding gains from profit distributable. Accounting system in general is a device of man as well as an outcome of the times, so we believe the application of integration of current cost accounting and general price level accounting can also be made better little by little through the ingenious of devices.

미래주의의 특성을 응용한 아트메이크업 디자인 연구

양재동,장수월,김혜균 사단법인 한국브랜드디자인학회 2023 브랜드디자인학연구 Vol.21 No.4

현대 과학 문명의 발전으로 컴퓨터와 첨단 통신기술이 점차 발달 되었으며, 이에 따른 새로운 산업의 생성으로 인해 우리의 생활양식도 다양한 변화를 가져오게 되었다. 최초의 달 착륙으로 인한 우주 시대의 개막으로 스페이스 패션과 함께 등장한 1960년대의 미래주의적 메이크업이 현대적인 의미의 시초이다. 특히 새천년에 대한 염원과 갈망으로 등장한 1990년대를 비롯하여 2000년대 후반에는 더 다양한 형태로 새롭게 등장하였다. 미래에 관한 불분명함으로 미래주의적 메이크업은 다른 어떤 형태의 메이크업 보다 다채로운 접근이 이루어지고 있다. 본 연구는 미래주의와 메이크업에 대한 이론적 배경을 위해 선행 연구 및 관련 문헌들을 통해 미래주의의 발생과 정의 그리고 메이크업의 정의와 발전에 대해 고찰하였다. 미래주의 대표 화가들의 그림 분석을 통해 미래주의 특성들을 선정하였고, 선정된 특성을 기반으로 9개의 메이크업 작품을 제작하였다. 미래주의에 관한 선행 연구 분석을통해 미래주의의 미적 특성으로 역동미, 기계미, 실험미를 도출하였으며, 이러한 특성을 살려 기계성 모티브 작품 3개, 실험성 모티브 작품 4개, 역동성 모티브 2개 총 9개의 작품을 제작했다. 본 연구를 통해 미래주의 운동의 특징과 예술적 의의를 알아보고, 미래주의의 특성과 아트 메이크업 디자인의 융합으로 현대적이고 창의적인 메이크업 디자인 요소로서의 추후 적극적인 연구가 수행되기를 기대한다. With the development of modern scientific civilization, computers and advanced communication technologies have gradually developed, and the creation of new industries has brought about various changes in our lifestyles. The futuristic makeup of the 1960s, which emerged with space fashion as the opening of the space age due to the first moon landing, is the beginning of the modern meaning. In particular, it emerged in more diverse forms in the late 2000s, including the 1990s, which emerged as a desire and longing for the new millennium Due to the ambiguity of the future, futuristic makeup is taking a more colorful approach than any other form of makeup. This study examined the occurrence and definition of futurism and the definition and development of makeup through prior research and related literature for the theoretical background of futurism and makeup. The characteristics of futurism were selected through the analysis of paintings by representative artists of futurism, and nine makeup works were produced based on the selected characteristics. Through the analysis of prior research on futurism, dynamism, mechanical beauty, and experimental beauty were derived as aesthetic characteristics of futurism, and using these characteristics, a total of nine works were produced, three mechanical motifs, four experimental motifs, and two dynamism motifs. Through this study, it is expected that the characteristics and artistic significance of the futuristic movement will be investigated, and active research as a modern and creative makeup design element will be conducted through the fusion of futuristic characteristics and art makeup design.
