본 논문은 SGML(Standard Generalized Markup Language) 문서를 DSSSL(Document Style Semantics and Specification Language)에 기반하여 포맷팅 처리하기 위한 SGML 문서 표현 시스템의 설계 및 구현에 관한 것이다. ISO(International Standard Organization)에서는 SGML 문서의 변환 및 포맷팅 처리의 기술을 위한 표준으로 DSSSL을 제안하였다. 이에 본 논문에서는 DSSSL 표준에서 정의한 모델에 따라 시스템을 설계하였고, SGML 문서를 온라인으로 포맷팅 처리하는 시스템을 개발하였다. 본 시스템은 한글 처리를 지원하면서 임의의 DTD(Document Type Definition), SGML 문서, DSSSL 스타일 시트에 대한 파싱 기능을 가지며, 텍스트뿐만 아니라 표, 목록, 그림 등 다양한 명세 표현을 처리할 수 있는 포맷터를 포함한다. This paper is for the design and implementation of SGML presentation system to format based on DSSSL (Document style semantics and specification Language). ISO proposed DSSSL as the technological standard for formatting and transforming SGML document. So, the body of this paper shows the design of this system in accordance with the model defined in DSSSL. This system, which is able to provide Korean, has Parsing function of arbitrary DTD, SGML document and DSSSL styles sheet, and contains a formatter that can manage various details, such as table, list, picture and others, as well as text.

Purpose: No ideal method for subdividing and assessing changes in neurons of the spinal cord during specific conditions has been established. We attempted to develop a method for subdividing spinal neurons using immunohistochemical and fluorescent staining, which is an important key towards understanding the mechanism of reflex voiding. Materials and Methods: Thirty Sprague-Dawley rats, weighting 200-300g, were divided into five groups. A cystometrogram was performed during saline or acetic acid instillation. We identified the neuronal pathway associated with the detrusor by injecting a pseudorabies virus(PRV) into the detrusor muscle and inspecting the changes in relation to different time sequences. An immunohistochemical staining method was used to stain the fos-protein encoded by the c-fos gene. Immunofluorescent staining was performed to evaluate changes in the neurons in relation to the voiding reflex, and the neurons then subdivided. Results: We confirmed pseudorabies virus(PRV) infection of the cells in the sacral parasympathetic nucleus through immunohistochemical staining two days after injection. On detection of an increase in c-fos positive cells after dividing the c-fos positive area of the L6 and S1 spinal cord into 4 sections, significant increases were observed in the sacral parasympathetic nucleus(SPN) and dorsal commissure(DCM). Double staining was performed to detect the neurons associated with the voiding reflex in the SPN and DCM areas showing overexpression of c-fos. Conclusions: The establishment of a method for detecting morphological changes, and subdividing neurons by immunohistochemical and fluorescent staining, may provide an important key towards understanding the mechanism of various neuromodulations of clinically applied treatments
