To respond to rapidly changing water circumstances such as climate change, drought, etc., the korean government (MOE) established four advanced strategies for integrated groundwater management. The first strategy is watershed-based management of groundwater. The second strategy is total quantity management of groundwater including improvement of groundwater preservation area policy and procedure of investigation for groundwater influence area, additional construction of groundwater dam, installation of large-scale public wells, extention of spilled groundwater use. The third strategy is prevention of groundwater contamination including expansion of monitoring wells, introducing declaration of groundwater contamination. The last strategy is advancement of groundwater information management including integrated management of data, setting up a big-data based open platform. The above-mentioned four strategies will be reflected in the 4th National Groundwater Management Plan to secure implementation power, and it is expected to laid the foundation for advanced and rational groundwater management system.

디지털 환경이 복잡해지고 사이버 공격이 정교해지면서 데이터 보호에 대한 중요성이 부각되고 있다. 데이터 유출, 시스템 침입, 인증 우회와 같은 다양한 보안 위협이 증가하면서 안전한 키 관리가 대두되고 있다. 키 관리 시스템(Key Management System, KMS)은 암호 키 생명주기 절차 전체를 관리하며, 여러 산업에서 사용되고 있다. 공공, 금융을 포함하는 다양한 산업의 환경에 맞는 요구 사항을 고려한 키 관리 시스템이 필요한 상황이다. 본 논문은 대표적인 산업에서 사용하는 키 관리 시스템을 비교 분석하여, 산업별 키 관리 시스템의 특성을 도출하는 것이 목적이다. 연구 방법은 문헌 및 기술 문서 분석, 사례 분석으로 정보를 수집하여, 산업 분야별 비교 분석을 진행하였다. 본 논문의 결과는 산업 환경에 맞는 키 관리 시스템을 도입하거나 개발 시 실질적인 가이드를 제공할 수 있을 것이다. 한계점은 분석한 산업 분야가 부족하고, 실험적 검증이 부족하였다. 이에 향후 연구에서 다양한 분야의 키 관리 시스템을 포함하여, 실험을 통한 구체적인 성능 테스트를 진행하고자 한다.

This study was performed to identify the current status of work environment management and to provide appropriate recommendations for small scale industry with less than 5 workers from September, 2000 to October, 2000 in Seoul city and Gyoung-gi province. The 211 companies were surveyed by checklist included the elements of management of work environment, hazardous chemicals, MSDS, personal protective equipment, and ventilation system. The proportion of metal products manufacturing and printing industries are 25.6 % and 22.3%, respectively. The daily working hours in printing industry is longer than others. The industries that produce potentially hazardous agents, such as noise, dust, metal, organic solvents, radiation and chemical material are pulp, plating, machinery, and printing, respectively. In above industries, only 2.8 % of those recognised and had MSDS. The proportion of companies providing fire extinguishers, safety showers are found to be 13.3 %, 7.1 %, respectively. Only 24.2 % of companies provided personal protective equipment to the workers. The ventilation system was operated in most of companies. But local exhaust ventilation system is provided to 22.3 % of those, also had not been annually inspected. This study showed that the current status of occupational safety and health was not appropriate for workers in small scale industries. It is suggested that annual physical examination have to be performed, MSDS usage must become widespread, and employer and emplyees in small scale industry should be educated for the treatment and storage of hazardous chemicals to improve the occupational safety and health of the working environment. also, regulatory standard has to be applied to local exhaust ventilation system in small scale industry to improve the working condition.

Some data into combined and sanitary sewer system were collected in order to find out the characteristics of discharge from first flush rainfall inflow. The inflow ratios of combined and sanitary sewer system were 0.46 and 0.27 during rains from various survey data. The average inflow ratio 0.31 was appropriate for general application because many watersheds were not classified clearly as combined or sanitary sewage treatment areas. The percentage of first flush loads in the whole BOD load was about 10%. This result was thought some meaningful, comparing with similarity of first flush pollution load contribution previous surveyed by KECO (2004).

For a sustainable development, the resources circulation system should be established and an environment-conscious activities are required at the same time. These activities should be also implemented in logistics area. Especially, green procurement activities in inbound logistics is recognized as a very important factors in the early phase of an environment-conscious activities. In this paper, we are to suggest the direction through statistical analysis of effects, and cause of influences of environmental procurement logistics activities on logistics performance by environmental logistics strategy and by the size of enterprises, and by Environmental Management System. This study was conducted with the subjects of manufacturing enterprises with concurrent reviews of literature and statistical analysis, and the meaning of this study would be the analysis of the influencers of environment-conscious procurement logistics activities on logistics performance different from existing logistics studies.

최근 유비쿼터스 컴퓨팅 환경에서 위치 추적 및 길찾기 서비스와 같은 위치 기반 서비스가 빠르게 발전하고 있다. 또한, 사용자 또는 사물의 위치가 다양한 장치 및 방법으로 획득되고 있다. 그러나, 기존의 위치 데이터 관리 시스템은 단일 위치 획득 시스템만을 기반으로 하여 설계되어 있어서 이러한 유비쿼터스 컴퓨팅 환경에는 많은 문제를 가지게 된다. 따라서, 본 논문에서는 유비쿼터스 컴퓨팅 환경의 다양한 센서로부터 획득되는 대용량의 위치 데이타를 효율적으로 저장하고 관리할 수 있는 위치 데이타 관리 시스템과 효율적인 위치 데이타 갱신을 위한 갱신 전략을 제시하였다. 특히, 본 논문에서 제시한 위치 데이타 관리 시스템은 유비쿼터스 컴퓨팅 환경에서 위치 기반의 효율적인 context-aware 서비스나, 자동화 서비스에 중요한 컴포넌트로 제공될 수 있다.

Recently, most of the information system use environment is changing to GUI environment based on windows and web. Most of the development tools for building such a GUI-based information system support object-oriented and event-driven programming concepts. However, there is still a lack of a development methodology that systematically supports event-based information system construction. From a business perspective, an information system is one that supports business processes efficiently and effectively to improve business performance. These business processes are composed of business activities which involve a series of business events. A business event is executed according to a business scenario. Therefore, it is necessary to grasp these events in the requirements analysis stage and to apply it on the system development methodology. However, information systems development methodology which systematically reflect the event processing concept still is insufficient. From this viewpoint, this paper proposes an event-driven scenario-based development methodology that can meet the recent development environment of information systems, and applies the proposed methodology to a small scale information system development case.

Workflow management system provides automation of job processes by maintaining shareability on information about various job process schedules and persons related to those schedules. Existing workflow management systems use file or database to store the information generated in those systems. However, file or database system could manage only non-complicated information for the workflow but not the information resources of an enterprise which is complicated and of various formats. Therefore, we need a data management system that could control those information resources. This system should manage the data which are distributed at several places geographically. Information Repository could meet those requirements. Information Repository may integrate, store and manage information resources requested by application systems. We have an international standard for the information repository, Information Resources Dictionary System(IRDS). The IRDS, however, does not support distributed environment. In this paper, we design and implement an information repository based on IRDS that may be operated in distributed environment. We verify that this information repository is more effective and is more effective than any other file or database system.
