The diagnostic requirements were suggested and explained regarding the systems of differentiation of symptoms and signs in the second year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows; - differential diagnosis according to condition of body fluid, differentiation of syndromes according to the state of qi and blood, differential diagnosis according to relative excessiveness or deficiency of yin and yang(氣血陰陽津液辨證) - differentiation of diseases according to pathological changes of the viscera and their interrelation - analyzing and differentiating of febrile diseases in accordance with the theory of the six channels(傷寒辨證) The individual diagnosis pattern was arranged by the diagnostic requirements in the following order : another name(異名), notion of diagnosis pattern, index of differentiation of symptoms and signs(辨證指標), the main point of diagnosis, analysis of diagnosis pattern(證候分析), discrimination of diagnosis pattern(證候鑑別), a way of curing a diseases(治法), prescription(處方), herb in common use(常用藥物), diseases appearing the diagnosis pattern(常見疾病), documents(文獻調査). This study was carried out on the basis of the Chinese documents and references.

Ad-hoc 무선망에서의 TCP 프로토콜 성능 분석

박승섭,이규남 釜慶大學校 2002 釜慶大學校 論文集 Vol.7 No.-

Ad-hoc networks consist of a set of mobile hosts that communicate using wireless links, without the use of other supporting communication facilities (such as base stations, etc.). Therefore, the topology of an Ad-hoc network freguently changes due to the movement of mobile host, which may lead to sudden packet loss. Recently, the large amount of research has focused on the routing protocols needed in such an environment. However, the researches of comparison analysis on TCP versions over Ad-hoc network have not fully studied. Accordingly, in this paper, TCP Reno, Sack, and Tahoe versions are analysed using DSR protocol which is the representative On-Demand routing protocol in Ad-hoc wireless network. As the result of this simulation, we know that TCP Reno has higher throughput than Sack and Tahoe, and TCP Reno has more stable performance than TCP tahoe and Sack, regardless of the speed of mobile node and the size of topology.

박승섭 釜山工業大學校 1995 論文集 Vol.37 No.-

DQDB MAN 프로토콜의 비등시성 트래픽을 전송하는데 있어서 분산큐잉 알고리즘을 이용하여 하나의 노드 동작으로도 전체 네트워크의 동작 상황을 평가할 수 있다. 본 연구에서는 SLAMⅡ언어로 하나의 노드에 대한 동작을 시뮬레이션하여 노드의 내부 구성 요소들 사이의 상호 연동 관계를 명확하게 해석하고, 버스의 용량에 따른 분산 큐잉 프로토콜의 전송 지연과 메시지 블록킹 시간등과의 상호 관계를 분석하였으며, 네트워크 부하와 지연시간과의 관계를 통해서 네트워크 노드 전체가 하나의 가상적인 큐를 형성함을 확인할 수 있었다. This paper analyzes the interaction among the components of node, evaluates the transmission delay time and message blocking time of distributed queueing protocol based on bus capacity, and confirmed the whole node in network to form the single virtual queue by relationship of network load and transmission delay. This study is evaluated by simulation of SLAMⅡ language.

ATM망에서의 ABR 트래픽 제어 알고리즘 성능분석에 관한 연구

박승섭 釜慶大學校 1999 釜慶大學校 論文集 Vol.4 No.1

In order to effectively control ABR traffic in ATM network, the interoperability of EFCI and ER switches becomes unavoidable. In this paper, we use the model of mixed EFCI-ER environment and compare the fairness of bandwidth allocation, drop rate, throughput by utilizing various ER switch algorithm. From our simulation results, we present the effective ER switch algorithms that have a less influence on network topologies and allocate the fair share of VC bandwidth.

패킷 폐기에 따른 ATM망 성능평가

박승섭,육동철 釜慶大學校 2000 釜慶大學校 論文集 Vol.5 No.-

ATM network mechanism is generally used for the solution of integrating multimedia service in high-speed Internet. In Internet protocol based on ATM services, the loss of single cell in ATM layer means that TCP packet is lost, as a result, TCP performance will be degraded. In this paper, to improve the TCP performance, we propose the new packet dropping scheme. To verify the efficiency of our proposed scheme, we compare our proposed scheme with other packet dropping scheme, i.e., EPD(Early Packet Discard), SPD (Selective Packet Dropping), and FBA(Fair Buffer Allocation). Through the simulation results, we know that our scheme can allocate more fairly each virtual channel(VC) than other schemes even if number of VC is increased, and no difference is shown in throughput.

박승섭 釜慶大學校 1997 釜慶大學校 論文集 Vol.2 No.2

As the size and complexity of network increase. Distributed Systems Management(DSM) will be signficant issue within information network in order to increase the high reliability and to improve the flexibility of network management. The OSI management model has several problems. The key problems are that it does not fully address the problem of how to develop communication protocol in support of DSM. and how to classify the management connection criteria. In this paper, to solve first problem described above, this paper propose the connectionless CMIP to accomplish for effectively managing the distributed manage-ment system, and indicate ots efficiency. This protocol is available to negotiate among the managing systems, to handle the dynamic informations. To work out sec-ond problem, we introduce the connection criteria in the hierarchy of management systems, and finally evaluate the efficiency of a suggested protocol during cooper-ative negotion among the managing systems.

이승원,박경섭 울산대학교 1997 공학연구논문집 Vol.28 No.1

적당한 성능의 광섬유 자이로스코프는 자동차 주행용의 회전율 측정 센서로 사용할 수 있다. 본 논문에서 구성한 광섬유 자이로스코프 시스템은 개회로 방식의 신호 처리를 하며, 단일 모드 광섬유와 방향성 결합기를 이용하여 시스템을 광섬유 일체식으로 구성하였다. 광원으로는 비편광 광원인 He-Ne 레이저를 사용하였다. 자동차 주행용으로 사용할 수 있도록 간단한 구성과 저가격이 되도록 하였다. 본 논문에서는 modified J₁…J₄ 방법을 응용한 신호 처리 방식을 사용하였다. 간섭계 출력을 고속 푸리에 변환(fast Fourier transform : FFT)하여 4 개의 연속 고조파를 구한 다음, modified J₁…J₄를 적용하여 변조도(modulation index)를 구한다. 이 방법은 광원의 파장변동이나 편광 상태의 변화 등에 상관없이 계측할 수 있다. 여기서 구한 변조도를 이용하여 Bessel 함수 ??를 계산한 결과와, 두 고조파의 비로 간단하게 회전율을 구할 수 있었다. Fiber-optic gyroscope of modest performance can be used as angular rate sensor for vechile navigation on land. A practical design is used an open-loop configuration with an all-fiber optical system together with single-mode fiber and directional coupler. We use the unpolarized light source, He-Ne laser as light source, and design simple construction for low cost. In this paper, we used the modified J₁…J₄ method which apply the signal processing technique. Measurements were made of the amplitudes of four harmonics in the electrical spectrum of the output of an interferometer using fast Fourier transform(FFT), and modified J₁…J₄ was used to determine the amplitude of the modulation index. This method allowed us independents of the wavelength fluctuation of the wavelength fluctuation of source and state of polarization changes in measurement. We can simply get the rotation rate with two harmonics ratio, Bessel function, ?? and the modulation depth.
