서범수 전북대학교 대학원 2009 국내석사

The multiple structure of the analog cellular parallel processing-based Viterbi decoder has been proposed. The study is the extension of the previous study of the analog cellular parallel processing-based Viterbi decoder which is faster and simpler than its digital counterpart. In this study, the timing circuits and the multiplexor circuits for the multiple structure have been designed and the signal characteristics of each part has been analyzed. Also, the causes of the signal distortion at over 250MHZ have been investigated. The proposed circuits is applied for decoding the PRLM signal for DVD. The hspice simulation results proves that the proposed multiple structure works properly to achieve the multiple times of its original speed.

비형식적 차원(Informal dimension)에서 발생하는 움직임과 이벤트의 통합을 적용한 Builing Landscape 계획안

서범수 경기대학교 건축전문대학원 2003 국내석사

본 논문은 비형식적인 차원(informal dimension)인 다이어그램(diagram)에서 발생하는 건축적 사건 중 특히 사건에서 확장되는 움직임의 관계에 주목하였다. 현대 도시사회에서 건축의 형태와 용도, 경제적 인과 관계는 더 이상 절대적인 것이 아니며, 진부한 것으로 여겨지게 되었다. 건축은 단순한 형태를 의미하지도 않고, 양식의 문제도 아닌 그렇다고 언어적으로 함축되는 것도 아니다. 건축의 비물질적(dematerialize) 차원에서 이루어지는 사람들의 행위와 사건(event)은 공간내에서 이루어지는 신체적 움직임에 대한 개념으로 확장된다. 사건과 공간은 서로 합쳐지는 것은 아니지만, 서로간에 관여하며 영향을 미친다. 이것은 곧 프로그램(program)의 문제를 야기시키는데, 현대 건축에서의 프로그램은 매우 가변적이어서 학교나 박물관이 이래야 한다라고 단정할 수 없으며, 테마 공원의 구성을 단정할 수 없다. 건축 프로그램은 불확정적으로 변하기 때문에 건물의 내용, 용도, 의미조차도 공간과 용도에 대한 충돌을 빚어내고 , 공간과 용도에 대한 불확실성을 증대시킨다. 무한한 목록이지만, 늘 형성되거나 조직되지 않은 소재, 그리고 형식화되거나 목적화되지 않은 기능, 분리될 수 없는 변수와 항상 관계를 맺는 이 비형식적인 새로운 차원을 푸코(Foucault, Michel)는 다이어그램(diagram)이라 정의한다. 다시 말해 건축은, 형식화되거나 목적화되지 않은 수 많은 변수들과 관계를 맺으며 생성되는 비형식적인 차원으로서, 다이어그램적(diagrammatic)이다. 건축은 끊임없이 구축물을 생산해내며, 무한히 유동적이고, 비형식적이며, 유연하다. 또한 불안정한 물리적 체계를 형성하며, 불균형상태이다. 건축이 다이어그램적(diagrammatic)이라는 것은 바로 이런 이유에서다. 건축은 시간적-공간적 복수성을 가지며, 그것들은 서로 유연한 힘의 관계를 구성하며, 증여와 역증여를 반복하며, 변이를 만든다. 변이를 만드는 건축은, 다이어그램적이며, 다이어그램의 연속과 불연속의 연결방식은, 뒤틀리고 구부러진 외부의 선을 지시하고 있다. 힘들은 생성속에 존재한다. 힘들의 생성의 존재는 다이어그램이 힘들 사이의 관계들의 집합을 보여주는 한 장소(lieu)가 아니라 오히려 '비장소 (non-lieu)'임을 의미한다. 즉, 다이어그램은 단지 변이의 장소이다. 더 이상 사물들은 지각되지 않고 또 명제들은 동일한 방식으로 말하여지지 않는다. 수 많은 계열들의 사회적 장(場)-field 인 다이어그램은, 힘의 작용 및 다른 힘들과의 관계 속에서 힘의 작용이나 반작용을 표시하는 특이적인 점(singular point)을 통과한다. 본 논문은 site내의 건물군의 성격을 세 개의 선분성(a segment of a line)으로 나눠 프로그램을 계획하고자한다. 1. Rigid line- 다주 상가 표준화되고 고정된 정체성을 추구하는 몰적-molar(위계화되고 구조화된 질서의 조직화) 선이며, 이분법적 주체성을 형성하거나 사회의 구성체로서 학생, 군인, 직장인등의 단계적 주체성을 형성한다. 2. Supple line- 다주 상가와 랜드스케이프, 수산물 직판장이 만나서 통합되는 공간 제도적으로 형성된 개별적 주체성에 균열이 생길때 나타나는 분열성(schizophrenic)으로 예를 들면, 남자인 나 속에 여성성을 느끼게 되거나 계급 구성원의 객관적 제약을 벗어나려고 하는 속성을 갖게되는 경우이다. 유연한 선분성, 즉 분열적 흐름(schiz flow)은 상대적 탈영토화(deterritorializing)의 작용을 하면서도 탈영토화를 봉쇄하고 경직된 선으로 다시 돌아가려는 재영토화(reterritorializing)로 작용할 수도 있는 일종의 전이적 상태로 개념화된다. 따라서 전이적 상태는 line of flight와 rigid line은 일차적인것이며, supple line은 그 둘 사이에서 동요한다. 3. Line of flight- 기존 수산물 직판장과 어린이 공원 극단적으로 탈영토화(deterritorializing)되고 탈코드화(decoding)된 흐름을 상징한다. 사회적 구조나 질서,제도적으로 틀지어진 주체성의 제약, 일반적인 구조 질서에서 벗어나 끊임없이 새로운 대상과 새로운 접속을 추구하는 욕망의 능동적 에너지를 말한다. 생산적이며 창조적일 수 있지만, 그것은 또한 파괴적이고 공격적일 수 있다. This thesis particularly focused on the relations of movements that spread from events, among architectural events that happen in diagrams, or informal dimension. Forms, uses and economic causations of buildings are no longer absolute but conventional in modern urban society. Architecture does not mean a mere form, nor a matter of style. It can not be implicated in language, either. People's acts and events done in dematerialized dimension of architecture are extended to a concept on physical movements conducted in space. Although events and space can not be incorporated, they give effects to and intervene in each other. This causes problems in programs. As programs of modern architecture are very variable, forms of architecture such as schools, museums and theme parks, are not fixed and definable. Since architecture programs vary indefinitely, even contents, uses and meaning of buildings cause conflicts on spae and uses, and deepen the uncertainty of space and uses. Michel Foucault defines the new informal dimension that is always concerned with matters, which is endless list, unformed, unorganized, unformalized and unfinalized fuctions, and the two variables being indissolubly linked, as diagram. In other words, architecture is informal dimension that resulted from a number of relations with variables which are not formalized nor intended, and it is diagrammatic. Architecture is indefinitely mobile, informal and flexible, and continuously produces buildings. In addition, it is in an unbalanced state and forms unstable physical systems. That explains why architecture is diagrammatic. Architecture has spatial and temporal plurality which consists flexible force relations, repeats gifting and reverse-gifting, and produces variations. Architecture that makes variations is diagrammatic, and the method to connect continuity and discontinuity of diagrams indicates outside line distorted and twisted. Forces exist in becoming. The existence of the forces' creation is not a lieu where diagrams show sets of force relations, but a non-lieu. That is, diagrams are a mere place for variation. Objects are no longer perceived, and propositions are no longer presented in the same way. Diagrams, a social field for a number of systems, pass through singular point, a special point indicating action or reaction of forces amidst action of forces or relations with other forces. This study aims to plan a program by dividing characteristics of buildings in site into three segments of line. 1. Rigid line - Dajoo-stores It is a molar line (organizing hierarchical and structurized order) to seek standardized and fixed identity, and forms dichotomous subjectivity or gradual subjectivity of students, soldiers, and salaried people as members of society. 2. Supple line - space where Dajoo-stores, landscape and fisheries wholesale markets are integrated Taking schizophrenic that comes when individual subjectivity systematically formed are cracked as an example, this is like a man finding feminity in himself or the case to get an attribute to be free from objective constraints of class members. Flexible segment of a line, or schiz flow, is conceptualized as a transitional state where it functions as relative deterritorializing, but also as reterrirorealizing at the same time, tending to seal deterritorializing and return to rigid line. therefore, line of flight and rigid line in a transitional state are primary, and supple line is swayed between the two. 3. Line of flight - existing fisheries wholesale markets and theme parks It symbolizes the flow that extremely deterritorialized and decoded. It refers to active energies desiring to break away from social structure or order, constraints of systematically formed subjectivity and general structural order, and continuously seek new connections with new subjects. It can be productive and creative, but also destroyable and aggressive at the same time.

새로운 용접 재료의 개발은 매우 복잡한 작업이 요구된다. 와이어에 충전되는 재료는 다양한 화학 성분을 포함한다. 안정적인 용접을 위해서는 화학 성분의 구성 요소와 야금학적 반응에 의해 결정된다. 매우 복잡한 상호 작용으로 인해 용접의 프로세스를 정량적으로 분석하는 것은 거의 불가능하다. 따라서 용접 재료의 설계는 설계자의 기본적인 용접에 대한 지식과 경험을 토대로 지금까지 수행되어왔다. 용접 재료의 개발은 대개 많은 파일럿 샘플에 대해 많은 테스트와 분석을 필요로 한다. 이 연구는 용접 재료 설계시 이러한 시험 및 분석의 양을 줄이기 위한 용접 재료의 특성을 예측하는 시스템을 목표로 한다. 본 연구에서는 플럭스 코어드 와이어의 작업성 및 용착 금속 조성을 분석하고 예측하기 위해 인공 신경망과 데이터베이스를 이용한 예측 시스템을 개발하였다. 인공 신경망은 복잡하고 비선형적인 문제를 해결하는 매우 강력한 도구이다. 그럼에도 주어진 목적을 위해 최적의 인공신경망 모델을 찾는 방법은 아직 알려지지 않았기 때문에 적절한 인공신경망 모델을 얻는데 어려움이 있다. 따라서 많은 시행착오와 적절한 인공신경망 모델을 얻는데 많은 기간이 필요하다. 본 연구에서는 탄력적 오류역전파 알고리즘과 데이터베이스를 결합하여 프로그램에 적용하였고 데이터베이스와 결합을 통해 인공신경망 모델을 쉽고 빠르게 생성하여 테스트할 수 있다. 탄력적 오류역전파 알고리즘은 매우 빠른 학습 알고리즘이고 기존의 일반화된 델타 규칙과 같은 역전파 알고리즘보다 수백 배 빠른 학습결과를 보여준다. The development of a new filler material having the required properties is a very complicated work. A filler material contains many kinds of chemical components. The properties of the weld deposited are determined by the chemical and metallurgical reaction of these components. It is nearly impossible to quantitatively analyze this process due to their highly complex interactions. Therefore the design of a filler material has been carried out up to now on the basis of fundamental metallurgical knowledge and experiences of filler material designers. The development of a filler material usually requires a lot of tests and analyses for many pilot samples. This research aims to develop the estimation system of the properties of a filler material for reducing the amount of these tests and analyses in developing a filler material. In this paper, an estimation system using an artificial neural network(ANN) and database was developed to analyze and predict the workability and the deposited metal composition of a flux cored wire. The neural network system is a very powerful tool to solve the complex and nonlinear problems. Nevertheless, it has a difficulty in obtaining an appropriate ANN model because the method to find optimal ANN model for any given purpose is not known yet. Therefore, it requires many trial and errors and much time to get the suitable ANN model. In this paper, the resilient backpropagation algorithm and database(DB)-coupled ANN system were applied. The resilient backpropagation algorithm is a very fast learning algorithm and shows the learning result several hundred times faster than the conventional backpropagation algorithm. The DB-coupled system can make many different ANN models and test easily and rapidly.

The introduction of local police system is an urgent problem and the main current as a systematic method for police officers abiding by the rapidly changing situation in public peace, their being respected by the people and their becoming incorruptible, friendly and reliable towards the people. After the establishment of president Rohs participatory government at the right moment, the introduction of the local police system has been strongly promoted as a part of the policy towards decentralization; therefore, Presidential Committee on Government Innovation & Decentralization and National Police Agency has been seriously investigating its introduction appropriate to the reality of our country. Nevertheless, it might be possible for the majority of police officers to be excluded in the process of its study and investigation even if they are those who would perform their duties in the frame of the local police system, while the majority of the police officers do not become a subject but an object in its introduction, only by reflecting the opinions of a few persons in charge or top executives and experts; as a consequence, it is apprehended that the police officers might be cynical and indifferent to its introduction. Therefore, it is considered important how the police officers think of its introduction so that this study will focus on the internal aspects rather than external circumstances surrounding police. In this aspect, the following questionnaires were answered and collected: the receptive attitudes towards its introduction by the function of the place, by the government office and by the origin of entering the office of the police officers; the range of its introduction; the location of the local police organizations; and the conversion of the ranks into local police officers. Based on these questionnaires, I have suggested some important issues relating to its introduction. Firstly, 64.4 percents of the police officers who responded to the questionnaires were in favor of the introduction of the local police system so that it could be noticed that their receptive attitudes towards its introduction have changed a lot more positive than those in the past. Secondly, as already mentioned in the road map in regard of the decentralization of the participatory government, it is seemingly possible not to have any frictions internally even with the swift enforcement of the local police system because more than 60 percents of the police officers favors its introduction in 2006 or 2007 through the presumable study & investigation and its process of legalizing from 2004 to 2005. Thirdly, one needs to study and investigate the standards that would be the most appropriate to the purpose of its introduction in its zero-base, not only thinking of its application in the level of metropolitan autonomous entities, but also keeping it in mind that almost 30 percents of the respondents is in favor of its introduction in the sphere of local autonomous entities. Fourthly, with regards to the location of the local police organizations functioned as a sub-agency or an immediate agency, 85.3 percents of the respondents, which is the absolute majority, demanded its installation independent of the local autonomous entity because of the possible corruption wrought by the interruption of local politicians. Fifthly, 30.4 percents of the respondents thought that all police officers should become local civil servants in order to let the justification of its introduction come true more completely with regards to the conversion of the ranks of local police officers into local civil servants in its introduction; therefore, one has to consider that special ranks should be kept as national civil servants. Sixthly, the majority of the police officers think of the local police system as public satisfaction and peace and the development of the entire organizations; however, others tend to evaluate it on behalf of individual interests or groundless and ambiguous suppositions. Therefore, there should be proper and objective education on the justification and management of the local police system. Seventhly, there should be some policy towards stirring up the morale through the restoration of the identity of the police officers triggered by the introduction of the local police system. As already mentioned above, the introduction of the local police system is an inevitable main current. It has come to a conclusion that the recognition of incumbent police officers has greatly become mature with regards to the local police system seen from the questionnaires answered by them. Therefore, there should be systematic methods to reflect the opinions of the police officers equipped with many experiences and know-how in terms of public peace from the step of its study and investigation of the most appropriate model to that of its settlement; in addition to this, politicians, local autonomous entities and all relevant groups including the police organizations should not think of their own hegemony but think of the people first in this country.
