City Train Technology that is large and complex system and consists of mechanical, electronic, electric, materials, computer, communication, civil/track etc. is very important area of railway industry, national fundamental industry. The standardization of city train system as a public transportation method and foundation of national economy is very important in order to do effective operation and to get fundamental technology, and the information system of the standards is required to operate the city train system effectively. By building data base of city train system design knowledge using computer-aided system engineering tool-Cradle, the system development issues and the design solutions are used by all engaged persons, and are managed by modeling and documentation. And this system will support architecture design consistently and effectively by applying this system to formalize early development process, to system requirements and configuration management, to system interface analysis and management and to system behavior analysis etc.. This study is for construction of data base of system design knowledge through making data base of many kinds of standards using CASE tool based on System Engineering Process, and introduces a model to support concurrent engineering for all engineers involved in system development allowing access to standard DB through Web from anywhere and at anytime.

The international government committee is progressing their agreements about intellectual property protection of traditional knowledge(TK), gene resource(GR), folklore(FL) in WIPO. It is in the course of selection with precedence of TK, GR, FL in WIPO, focused on discussions about listing of TK documents, standardization of DB construction, sharing and profit distribution of GR. We made some plans to deal with agreements in WIPO. These plans consist of 5 subjects which are investigation about intellectual property related laws and systems, study of examination and finding, construction of DB information, development of value evaluation system, development of industrialization system with TK, GR, We suggest preceding details about 5 subjects respectively. It is the character of this plan that patent information DB system of TK, GR is the axis. It is the most important thing in these plans to succeed that we have to have connections with expert groups in order parts and government officials, taking whole supports of government because our traditional medical related study basis is weak.

Objective : Classification of herbal formulas through the analysis of compositional herb's is a suitable method in the aspects of the effective applications of herbal formulas. However, these classification methods have some problems in dealing with lots of herbal formulas because the estimations of herbal formula's effects are dependent upon one's memory. In this study, we aimed to establish the effective methodology to elicit the classified herbal formula's chart by introducing the DB systems without interfering with non-standard terms. Results : We have known that this plan is realized by follow methods. We entered the herbs informations of the composition of herbal formulas into database, made an alias tables of corresponding herbs, and achieved standardization of herb's informations. Using these databases, we made the classified herbal formula's chart according to the presence and the treatment informations of herbs.

This study investigated the current management staus of chemical substance information on Material Safety Data Sheets(MSDS) and Chemical Information Cards(CIC) provided by Korea Occupational Safety & Health Agency(KOSHA) and also researched the kind and the characteristics of chemical substance information provided in other organizations. MSDS DB in Korean provided on KOSHANET(which is Kosha website) is 50,802 in total, among whom are single chemical substances with 31,870 kinds(18,932%) and are mixed chemical substances with 31,870 kinds(62.7%). The number of visiting MSDS DB on KOSHANET for the search of chemicals was 2,049,806. The number has increased each year. The CIC provided for workplaces is all 542 kinds : 14 harmful substances subject to permission, 168 harmful substances subject to management, 360 KOEL(Korean Occupational Exposure Limits) establishment substances. MSDS internationally provided by organizations producing MSDS DB was written with 16 sections, which is suitable for the writing basis of American Standards Institute(ANSI) and International Organization for Standardization(ISO) and provided chemical substance information on more than 100,000 kinds in most organizations.

광역 교통망 및 통신기술의 발전에 따라 광역경제권의 활성화를 위한 협력체계의 중요성이 날로 증대되고 있다. 이에 본 연구는 동남권 광역경제권을 대상으로 GIS 기반의 산업체 정보 공유를 목적으로 동남권 산업체 정보시스템을 구축하였다. 동남권의 경우 제조업 중심의 산업 집적지로서 행정경계를 넘어 산업체간의 근접성과 연결성을 고려한 효율적인 산업 클러스터 및 협력체계 운영이 요구된다. 정보시스템의 DB 구축을 위해 부산, 울산, 경남에서 구축되어진 산업체 DB를 활용하여 정보시스템을 구축한 바, 각 지자체간 데이터의 불일치와 GIS기반의 위치정보 미흡으로 인한 여러 가지 문제점을 발견하였다. 이의 해결을 위해서는 수집 및 배포, 활용과정을 고려한 표준화가 시급한 것으로 분석되었다. 본 연구는 산업체 정보의 공간정보화를 위해 지적도와 수치지도를 활용하여 웹상에서 관리자-사용자 쌍방향간의 정보생성 및 단계별 접근이 가능한 2-way 방식의 산업체 정보시스템을 구축하였다. 본 연구의 결과는 동남권 산업육성을 위한 협력체계 및 공동대응을 위한 산업체 정보 공유체계의 기초적 틀을 제공하였다는 데 그 의의가 있다고 하겠다.

SE(System Engineering)은 이미 선진국에서 우주항공, 국방 등 다양한 분야에 걸쳐 적용되고 있으나 국내에서는 초기단계로서 철도 및 국방분야에서 제한적으로 적용하고 있는 것이 현실이다. SE기술은 적용범위가 매우 광범위하기 때문에 본 연구에서는 SE기술에서 문서관리 및 요구사항 분석기술을 적용하여 본 연구의 목표인 표준화 기준 작성 및 핵심장치 개발을 효율적으로 수행하는 방법을 연구하였다. 표준화기준에 대하여는 SE 도구를 사용하여 표준화기준간의 추적성 및 이력관리를 수행하였고 사업에서 생성된 모든 문서들을 DB로 구축하여 참여기관들이 사업에 필요한 정보를 공유하도록 하였다. 기본설계단계에서 기능분석을 통하여 핵심장치인 지능형 역사감시시스템의 요구사항이 적절한 지를 검토하였고 요구사항에 따라 지능형 역사감시시스템이 개발되는 지를 관리하였으며 최종적으로 검증된 요구사항을 지능형 역사감시시스템의 표준화기준으로 고시할 계획이다.

Histopathology is a well-established standard diagnosis employed for the majority of malignancies, including breast cancer. Nevertheless, despite training and standardization, it is considered operator-dependent and errors are still a concern. Fractal dimension analysis is a computational image processing technique that allows assessing the degree of complexity in patterns. We aimed here at providing a robust and easily attainable method for introducing computer-assisted techniques to histopathology laboratories. Slides from two databases were used: A) Breast Cancer Histopathological; and B) Grand Challenge on Breast Cancer Histology. Set A contained 2480 images from 24 patients with benign alterations, and 5429 images from 58 patients with breast cancer. Set B comprised 100 images of each type: normal tissue, benign alterations, in situ carcinoma, and invasive carcinoma. All images were analyzed with the FracLac algorithm in the ImageJ computational environment to yield the box count fractal dimension (Db) results. Images on set A on 40x magnification were statistically different (p = 0.0003), whereas images on 400x did not present differences in their means. On set B, the mean Db values presented promising statistical differences when comparing. Normal and/or benign images to in situ and/or invasive carcinoma (all p < 0.0001). Interestingly, there was no difference when comparing normal tissue to benign alterations. These data corroborate with previous work in which fractal analysis allowed differentiating malignancies. Computer-aided diagnosis algorithms may beneficiate from using Db data; specific Db cut-off values may yield ~ 99% specificity in diagnosing breast cancer. Furthermore, the fact that it allows assessing tissue complexity, this tool may be used to understand the progression of the histological alterations in cancer.
