네트워크 모니터는 2002년 1월 현대 단국대학교 멀티미디어 통신망 연구실에서 연구개발 중인 장비이다. 주 기능은 이더넷 등의 네트워크 환경에서 원격의 디스플레이 장치에 사용자의 PC, Notebook, PDA 화면을 전송하여 표현하는 것을 목적으로 한다. 이 장비는 대형회의장과 같은 공공장소에 있는 큰 디스플레이 장치에 탑재되어 사용자에게 편이성을 제공한다. 본 논문에서는 네트워크 모니터 시스템의 기반이 되는 포로토콜과 임베디드화 되었을 때 필요한 모듈과 그 운용 방안 등에 관하여 논의한다. A Network Monitor is developing at Multimedia Communication Lab, of DanKook University since 2001. The main function of this equipment is that is transmits the display information of PC, notebook and PDA which are located in distance and have display device on networks like ethernet. A Network Monitor can be mounted on large display device at conference hall or public place. In this paper, two main ideas are discussed. One is a protocol for network monitor system, the other is a module for embedded system and its operating method.

신경세포의 기능을 등가적으로 표현할 때 활성화 함수는 비선형적이며 이의 구현을 위해 고가의 수치계산 전용 칩이나 고속 컴퓨터를 사용하여왔다. 본논문에서는 이 함수를 근사화하여 구현하기 위해 오차의 종류와 그 크기에 따른 선형함수의 갯수를 조사하고 이를 구현하기 위한 하드웨어 구성 회로를 고찰하였다. The activation function is nonlinear when the equivalent model of a neuron is considered. Expensive numeric processors or a high speed computer has been used to realize the function. In this paper two kinds of error are considered and the number of linear functions in a certain interval is investigated. A new hardware implementation is studied to realize a number of linear functions.

Since 1970, computer aided circuits simulation or circuits design has been stuided. At that time, the size of a circuit was under 1000 gates and SPICE program was proposed for the first time. In the year of 1980, the CAD program was upgraded to CAE with numerical computing power. The size of a circuit was in the range of 10,000 to 100,000 gates and schematic capture or logic simulation was utilized. In the year of 1990, an electronic design automation using a hardware description language is used widely. Such wide use of a hardware description language is apparent so that it is necessary to develop a courseware of the language for the effective and efficient learning. In this paper, the courseware targets to the integrated education of a digital system analysis. a design theory, and a hardware description language training. In order to achieve the integration, the learning of a digital system analysis, that of a design theory, and the training of a hardware description language is simultaneously performed. This paper consists of two subjects. One is that the learning of a digital system analysis, that of a design theory, and the training of a hardware description language is simultaneously performed. The other is that the courseware is running on CD-ROM title. To learn the hardware description language, the explanation using sound or moving images, setting-up of a simulation or a synthesis program., and simulating are executed on a CD-ROM title. And also, we proposed an integrated education systems for the hardware description language. It consists of the presentation systems and the experiment systems. The theory presentation systems supports multimedia display functions.

In this paper, data rate of VDSL system was analyzed in noise and crosstalk environment. For this paper, Matlab tool was used to analyze the performance of VDSL system. Various "VDSL Test Loop" are used which is suggested by ANSI DSL Standard group T1E1.4. Many parameters, "Noise Model A", "Noise Model F", duplex method VDSL-998 which is suggested FDD plan by ANSI was used. The most of conditions for simulation are followed to the ANSI Standard "Spectrum management" Lots of data have been obtained according to the different conditions of the test loops. The result shows that the data rate of VDSL system is decreased due to the other DSL signals in the same cable bundle. And also there was more reduced data rate in case of Noise Model F than that of Noise Model A.

It has been studied on new image photograh processing, analysis and storing method for medical images in the application field of medical electronic engineering. As a strong method of analysis for comparing the initial and final state of longterm diagnose among such system functions. we use DSR(digital subtraction radiography) which enables comparison by superimposing over pair images obtained from the initial and final state during observation period or executing subtraction. To perform DSR, geometric correction and contrast correction between two images should be done firstly. This paper is based on CDF(Cumulative Density Function). The subtraction operation between two images has been done to confirm that two images’ contrast became identical through contrast correction. We obtained image enhancement through the deletion of background by histogram clipping.
DBS와 Brij 30의 혼합미셀화에 미치는 n-Butanol의 효과
박인정,이병환 한국기술교육대학교 2006 論文集 Vol.12 No.1
The critical micelle concentrations(CMC^(*)) and the counter ion binding constants(B) in a micellar state of the mixed surfactant systems of sodium dodecylbenzenesulfonate(DBS) with polyoxyethylene(4) lauryl ether(Brij 30) at 25℃ in aqueous solutions of n-butanol were determined as a function of α_(1)(the overall mole fraction of DBS) by the use of electric conductivity method and surface tensiometer method. Various thermodynamic parameters(X_(i), γ_(i), C_(i), a_(i)^(m), β, △H_(mix) and △G_(m)^(o)) for the micellization of DBS/Brij 30 mixtures were calculated and analyzed by means of the equations derived from the nonideal mixed micelle model. The effect of n-butanol on the mixed micellization of that mixed surfactant system has been analyzed by comparing the values of the thermodynamic parameters in pure water with those in aqueous solutions of n-butanol (0.1M and 0.2M).

이 논문은 하이데거의 ‘실존적 불안’에 대해 고찰하고자 한다. 불안은 자기존재를 가지고 있지 않은 존재이며 세계와의 관계 속에서 자신의 존재를 드러낼 수 있다. 따라서 세계를 고찰하지 않고 불안을 온전히 드러낼 수 없다. 본 논문은 이를 위해 먼저 인간과 세계에 대해 보편적 토대를 마련하고자 하는 전통철학의 관점을 하이데거의 입장을 따라 비판적으로 고찰하고, 세계를 각자성 속에 나타나게 하는 ‘실존적 불안’에 대해 고찰함으로써 인간본질로서의 실존적 불안의 의미를 온전히 드러내고자 한다. 전통철학에서 세계는 객관적 세계이다. 객관적 세계는 이성을 통해 바라 볼 수 있는 이론적 세계이다. 이론적 세계는 삶의 장으로서의 세계가 아니다. 삶의 장으로서의 세계는 인간과 세계가 서로 함께 속해 있어야 가능하다. 그런데 전통철학은 인간과 세계의 함께 속해 있음을 이성의 ‘인식함’에서 해결하고 있다. 이성의 인식함 속에는 이론적 세계만 나타날 뿐이다. 따라서 전통철학이 삶의 장으로서의 세계를 마련하기 위해서는 인간본질에 대한 새로운 모색이 필요하다. 하이데거는 삶의 장으로서의 세계를 마련하는 인간본질을 ‘불안’이라고 말한다. 불안은 현존재와 세계를 서로 함께 있음의 공속 관계 속에 나타나게 한다. 그리고 인간과 세계의 공속관계 속에서 세계는 삶의 장으로서의 ‘나의 세계’가 된다. 불안 속에서 현존재는 자기존재가능을 위해 세계를 형성해 가야하는 존재로 나타나기 때문이다. 따라서 삶의 장으로서의 세계를 드러내는 인간본질은 이성이 아니라 ‘불안’이다. 불안 속에서 현존재는 자신의 존재가능을 위해 삶의 장으로서의 세계를 형성할 수 있는 ‘자유존재’가 된다. This paper examines Heidegger’s ‘existential anxiety’. Anxiety is a non-existent being and can reveal its existence in relation to the world. Therefore, we can not reveal anxiety without considering the world. In this paper, first of all, we examine critically the viewpoint of the traditional philosophy to establish a universal basis for human and world, and examine the existential anxiety which makes the world appear in an individual world, and to reveal the meaning of existential anxiety as a whole. In traditional philosophy, the world is an objective world. The objective world is a theoretical world that can be seen through reason. The theoretical world is not a world of life. The world as a field of life can only exist if human beings and the world belong together. However, traditional philosophy is resolved in the recognition of the reason that human being and the world are together. In the recognition of reason, only the theoretical world appears. Therefore, in order for traditional philosophy to establish a world of life, a new search for human nature is needed. Heidegger says that the human nature of setting up a world of life is 'anxiety'. Anxiety makes Dasein and the world appear in the relationship of being together. And in the relationship between man and the world, the world becomes 'my world' as the field of life. In anxiety, Dasein appears as a being who must form the world to be able to be self–existent. Therefore, the human nature that reveals the world as a field of life is not reason but anxiety. In anxiety, Dasein becomes a 'free being' that can form a world of life for the sake of being able to exist.
