한자(漢子)로 기술된 용어를 한글로 자동변환하여 색인어로 사용하는 경우에 한글의 음운체계나 해당 시스템의 색인정책에 맞지 않는 일이 생기게 된다. 이런 문제가 생기는 원인은 해당 한자에 대응하는 정확한 한글을 입력하지 않고 변환하였을 경우, 해당 한자의 음이 없거나 한자와의 음운체계가 달라 생기는 경우 및 별도의 색인정책이 있는 경우 등을 생각할 수 있다. 본고에서는 KS C 5601 표준코드(이하 표준코드라 한다)를 기준으로 한자(漢子)의 다음자(多音子)를 조사하였다. 다음자(多音子)가 포함되어 있는 사전용어와 다음자(多音子)파일을 이용하여 매핑파일을 구축함과 동시에 매핑파일을 보완함으로써 한자(漢子)로 기술된 용어의 바른 한글음을 자동생성하여 색인어로 사용할 수 있는 방안에 대하여 논한다.

프랙탈이란 말은 라틴어 Fractus(부서진 상태를 뜻함)에서 유래되었으며, 1975년 Mandelbrot가 수학 및 자연계의 비정규적 패턴들에 대한 체계적 고찰을 담은 자신의 에세이의 표제를 주기 위해서 만들었다 (〔6〕). 프랙탈을 기술하는데 있어서 가장 중요한 양은 차원(dimension)으로 프랙탈 차원은 정수차원이 아닌 실수 차원을 갖는다. 이 논문에서는 box counting 차원, Hausdorff 차원, s-potential 및 s-energy등에 대한 정의를 하고 정리 2.8, 정리 3.1및 정리 3.2을 증명하고자 한다.

Local anesthesia is routine procedure in dental practices and has several complication. One of them, needle fracture is not uncommon in past, but rare in recent. The number of cases reported in the literature of broken needle in local anesthetic procedure has shown a marked decrease since the use of disposable spiral-constructed dental needle began. This complication results from lack of patient cooperation, inaccurate anesthetic technique, sudden movement of patient, error in the manufacturing procedure, use of short needle, and bending before use. Most common site is pterygomandibular space during inf. alveolar nerve block. In two patients, we removed broken needles under general anesthesia without complication. So we report cases with review of literatures.

This paper is on the generalized singular perturbation approximation (GSPA) preserving the discrete positive real property. We transform the discrete positive real(PR) system into a stochastically banlanced system and get the reduced order discrete system from the GSPA of the full order stochastically balanced system. eSPECIALLY, WHEN THE FREE PARAMETER OF THE gspa IS .+-.1, we show that the reduced order discrete system retains stability, minimality, and positive real and stochstically balancing properties. And we derived the .inf.-norm error bound with the reduced order discrete strictly positive real(SPR) system by the proposed method. Finally, we give an example to ascertain the properties of the proposed reduced order discrete system and to compare with the conventional methods.

In the problem of some sequential estimation, the stopping times may be written in the form $N(c) = inf{n \geq n_0; n \geq c^2 S^2_n/\delta^2 (\bar{X}_n)}$ where ${s^2_n}$ and ${\bar{X}_n}$ are the sequences of sample variance and sample mean of the independently and identically distributed (i.i.d.) random variables with distribution $F_{\theta}(x), \theta \in \Theta$, respectively, and $\delta$ is either constant or any given positive real valued function. We obtain some asymptotic normality and asymptotic expectation of the N(c) in various limiting situations. Specially, uniform asymptotic normality and uniform asymptotic expectation of the N(c) are given.

The author describes document delivery services and document usage patterns of domestic users based on usage statistical data about photocopying service of KINITI that the most important document delivery organization in Korea. And investigated ordering procedures of users, number of document processed and rejected in photocopying service, and delivery methods for users and so on. In FY 1996, number of document in photocopying service increased 2.4 percent in proportion to previous year.

이 논문은 레거시 시스템에 대한 도메인 분석을 통한 소프트웨어 컴포넌트 식별을 제안하고자 한다. 이 방법은 공통/비공통 프로세스 컴포넌트를 추출하기 위한 워크플로우 기반의 도메인 모델링으로, 점진적, 반복적으로 각각의 사용자(개발자, 설계자, 시험자 등등)에게 적당한 크기의 프로세스 컴포넌트를 추출하고 마지막 단계에서 UML 기법으로 컴포넌트 내의 객체를 추출하고자 한다. 그래서 기존의 워크플로우 메커니즘의 확장 보완을 제시한다. 이 방법 적용 예로써 학생 학위 허가 시스템(Student Degree Matriculation System)을 적용 사례로 이용한다. 그리고 이 확장된 워크플로우 메커니즘은 IT 분야나 비즈니스 모델링은 물론 병렬 시스템, 텔레 통신 시스템, 실시간 시스템까지도 모델링 할 수 있으리라 본다.

This paper deals with the geometric fitting algorithms for parametric curves and surfaces in 2-D/3-D space, which estimate the curve/surface parameters by minimizing the square sum of the shortest distances between the curve/surface and the given points. We identify three algorithmic approaches for solving the nonlinear problem of geometric fitting. As their general implementation we describe a new algorithm for geometric fitting of parametric curves and surfaces. The curve/surface parameters are estimated in terms of form, position, and rotation parameters. We test and evaluate the performances of the algorithms with fitting examples.

This study was carried out to prove the anti-allergic effect of SPS-GM, which is gained by controlled Cytokines making all the difference to Th2 cell development. The results were obtained as follows : 1. From the SPS-GM treatment about BMC cell, in case of the IL-4, an important factor of the Th2 cell development, SPS-GM didn't show considerable effect. 2. The INF-${\gammer}$, mutual Cytokines of IL-4, was increased more than twice. 3. Histamine from the Master cell and Nitric oxide from indisposition response were a little decreased. According to the above results, it is suggested that SPS-GM has anti-allergic effect.

This study was peformed to investigate possible mechanisms underlying possible effect of Coicis Semen composition (CSC) on inflammatory diseases using in vivo model of RA in the mice. Results are summarized as follows. In production of inflammatory cytokines, INF-${\gamma}$ in the spleen and IL-6 in the serum were decreased by CSC treatment. TNF-${\alpha}$ in serum was significantly decreased, IL-4 in the spleen was significantly increased by CSC treatment. In production of rheumatoid factors, IgM and IgG were significantly decreased by CSC treatment. The present data suggest that CSC treatment can improve pathological damage by CIA. So we expect that CSC should be used as a effective drugs for not only rheumatoid arthritis but also another autoimmune disease. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.
