This study is a case study for in-house developed Record Maintenance and Management (RMMS) which is a digital data storage/retrieval system in a GIS-enabled solution. RMMS is designed for reorganizing submitted architectural drawings associated with scanned drawings files & geodatabase, managing metadata/table and geometric features in ArcSDE/Enterprise geodatabase format. The birth of the RMMS was borne out of a necessity for a modernized approach in digital file basis to provide improved customer services for various architectural drawings and associated with geo-spatial and its attribute information. Through a case study for building permit & review practice implemented on an internet-based Electronic Architectural administration Information System (EAIS) at the local governments in Korea, this study is able to derive differences between GIS-enabled RMMS system implemented in the Richmond City and internet-based EAIS system implemented in the local government in Korea. In an effort to be the most effective, it presents meaningful ways of maximizing efficiency in record maintenance & management system derived from the case studies that looked into in ways of a method in RMMS' operation, implementation on GIS platform, mutual interface among various programs with various digital files and finally technical supports and system development /upgrade.

Background: The European Centre for Ecotoxicology and Toxicology of Chemicals' Targeted Risk Assessment (ECETOC TRA) tool has been recognized by EU REACH as a preferred approach for calculating worker health risks from chemicals. Objectives: The applicability of the ECETOC TRA to occupational exposure estimation from industrial uses of methanol was studied by inputting surveyed and varied parameters for TRA estimation as well as through comparison with measured data. Methods: Information on uses of methanol was collected from seven working environment monitoring reports along with the measured exposure data. Input parameters for TRA estimation such as operating conditions (OCs), risk management measures (RMMs) and process categories (PROCs) were surveyed. To compare with measured exposures, parameters from the surveyed conditions of ventilation but no use of respiratory protection were applied. Results: PROCs 4, 5, 8a, 10, and 15 were assigned to ten uses of methanol. The uses include as a solvent for manufacturing sun cream, surfactants, dyestuffs, films and adhesives. Methanol was also used as a component in a release agent, hardening media and mold wash for cast products as well as a component of hard-coating solution and a viscosity-controlling agent for manufacturing glass lenses. PROC 8a and PROC 10 of a cast product manufacturer without LEV (local exhaust ventilation) and general ventilation as well as no respiratory protection resulted in the highest exposure to methanol. Assuming the identical worst OCs and RMMs for all uses, exposures from PROC 5, 8a, and 10 were the same and the highest followed by PROC 4 and 15. The estimation resulted in higher exposures in nine uses except one use where measured exposure approximated exposures without RMMs. Conclusions: The role of ECETOC TRA as a conservative exposure assessment tool was confirmed by comparison with measured data. Moreover, it can guide which RMMs should be applied for the safe use of methanol.

이 논문에서는 실제 설치예정인 도시가스 고압배관에 대하여 정량적 위험성 평가를 실시하고, 평가 결과 위험이 허용영역 밖에 위치하는 경우에는 위험경감조치를 도출하였다. 또한, 도출한 위험경감조치별 위험감소율을 계산하였다. 정량적 위험성 평가결과, 복사열에 의한 사고피해거리는 바람의 속도와 대기안정도에 따라 크게 좌우됨을 알 수 있었다. 위험감소율이 가장 큰 조치는 배관의 부식관리, MOV 설치 및 타공사로 인한 배관손상방지조치를 모두 이행하도록 하는 10번 조치로서 75%의 위험감소효과가 있었다.

2007년 6월 시행된 유럽 신(新)화학물질관리제도(REACH, Registration, Evaluation, Authorization and Restriction of CHemicals)에서 물질 제조자가 공급망 상 제공해야 하는 법적 의무 사항인 확장된물질안전보건자료(eSDS, extended Safety Data Sheet)에 대하여, 본 총설에서는 eSDS의 개념 파악과 함께 노출시나리오(ES, Exposure Scenario) 작성 방법에 대한 유럽의 개발 동향을 기반으로 노출시나리오의 구성요소 및 각 구성요소별 주요 입력정보 그리고 단계별 노출시나리오 작성 방법을 알아보았다. 노출시나리오 작성에 필요한 정보로는 용도기술어 시스템(UDS, Use Descriptor System), 작업조건(OC, Operational Condition) 및 위해성관리대책(RMM, Risk Management Measure)이 조사되어 이에 대해 구체적인 이해를 도모하였다. 근로자, 환경, 소비자를 평가 대상으로 하는 기존의 주요 노출 평가 툴의 특징을 살펴보고, REACH 하의 노출시나리오 생성을 실행하기 위해 유럽화학물질청(ECHA, European Chemicals Agency)에서 최종 개발하여 발표한 노출 평가 툴인 Chesar (Chemical Safety Assessment and Report tool)의 구성을 알아보았다. EU 집행위에서 개발한 유기용매 분야의 일반 노출시나리오 (GES, Generic Exposure Scenario) 사례를 소개하였고, 3단계로 구분할 수 있는 노출시나리오 작성 과정 중에서 국내 수출 중소기업에서 담당할 부분 및 활용 방안을 제시하였다.
