In this paper, we propose a real-tim measurement management system UI development linked the Water treatment facilities broadband Convergence Network. The sensor and the image data received by the server develop a program to interact with Web through water treatment facilities broadband convergence network. So, Separately develop UI capable of independently operating. Building a web server for remote monitoring of the transmission sensor and the image data. And Monitoring and control is possible the sensor data and image data through the Web-based UI. We can grasp the current state such as measurement time, concentration and depth of interface through the proposed real-time measurement management system UI development liked the water treatment facilities broadband convergence network. So, we can check in whether the normal operation of water treatment facilities and whether the casualties such as fire and security. As well as real time to see the information at a glance due to UI development can be raal-time monitoring of real-time measurement management system.

As new information technology emerges, companies are introducing an Enterprise Security Management system to cope with new security threats, reducing redundant investments and waste of resources and counteracting security threats. Therefore, it is necessary to construct a security evaluation metric based on related standards to demonstrate that the Enterprise Security Management(ESM) System meets security. Therefore, in order to construct a metric for evaluating the security of the ESM, this study analyzed the security quality related requirements of the ESM and constructed a metric for measuring the degree of satisfaction. This metric provides synergies through the unification of security assessments that comply with ISO/IEC 15408 and ISO/IEC 25000 standards. It is expected that the evaluation model of the security quality level of ESM will be established and the evaluation method of ESM will be standardized in the future.

Recently, environment facilities are able to manage real-time data collection and record management through integrated broadband modem LAN switching technology. Therefore, it need more stable and efficient facility management. So, we required practical use of environmental facilities convergence based on broadband integrated modem. In this paper, we proposed an integrated broadband modem LAN switching technology which can applicable to the environment facility. Also, we presented integrated broadband modem of design plan and communication system. And it received data inside of environment facility using the two communication methods(IEEE802.11x and IEEE802.15.4x). Then, our proposed integrated broadband modem LAN switching technology will prioritize processing data when emergency happen through collecting data, analysis data and processing. Lastly, we proved usefulness by experiment and simulation analysis.

The importance of information management has been emphasized in Korean construction industry, Both public and private have invested to establish and operate construction CALS, construction management (CM), computer integrated construction(CIC), and earned value management system(EVMS). A standard construction information classification system is essential to operate the systems mentioned above. Therefore, Korean government released Integrated Construction Information Classification System(ICICS) in 2001. However, the ICICS is not widely used in construction due to: 1) difficulty of changing existing system, 2) insufficient publicity of the ICICS, and 3) no legal binding force. Especially, participants in construction do not recognize applicability of the ICICS. This research surveyed the degree of recognition and utilization of the ICICS. This survey includes both customized classification systems used by companies and the ICICS and investigates the degree of utilization and drawbacks. The results show some construction companies use their own classification systems and the others use the ICICS prepared by the government. Furthermore, the degree of recognition is in sufficient. The degree of use in design management, specifications, cost and schedule management is very limited. The publicity and education are critical to induce the utilization of the ICICS. The necessity of revision was recommended based on pilot project study that is performed to measure the degree of application of ICICS on the projects. Therefore, this research proposes the measurement model for information application and analyzes the degree of utilization of the ICICS in different phases of construction.

In this paper, the fire extinguisher maintenance system using smart NFC communication and the real-time pressure measurement is proposed. The proposed system consists of three steps in the flow of information. The first step is to identify the fire extinguisher through NFC tagging in the fire extinguisher module using the smart device. The fire extinguisher appearance check and the real-time pressure measurement is performed in the second step, and the last step sends the check status information to the management server. In particular, the actual pressure value is calculated based on the angle of the green area and the indicating needle. Some experiments are conducted so as to verify the proposed system, and as a result, the proposed system shows that the administrator can effectively control the status information of fire safety check.

The strategic management process includes the establishment of competitive strategy, its implementation and the measurement of its performance. The sucess of strategic management largely depends on the integration of strategic management process into a managerial tool. This study is on the integration of strategic management process into a managerial tool based on the power process, so that it contributes to strategic success or sustainable competitive advantage of a ￡inn In order to do this, I discussed the principles of the power process, its characteristics, and then suggest their applications to the integration of the strategic management process. According to the results, the power process offers a theoretical and managerial tool which integrates the establishment of competitive strategy with managerial concepts, so that it increases the likelihood of strategic success. Furthermore I discussed the position of the power process approach to competitive advantage in a manner that displays similarities and differences with existing approaches such as industry organizational, resource-based and game theory approach.

IT 프로젝트는 많은 불확실성을 내포하고 있다. 이러한 불확실성은 프로젝트의 성공적인 수행에 좋지 않은 영향을 미치게 된다. 이처럼 악영향을 미치는 근본적인 이유는 프로젝트가 가지고 있는 잠재적 위험(Risk)이 중요한 원인이라 할 수 있다. CMMI-DEV(Capability Maturity Model Integration for Development, version 1.2)모델을 기반으로 IT 프로젝트를 수행하는 많은 조직에서 소프트웨어 개발시 실제 CMMI-DEV 모델을 적용하여 IT 프로젝트의 위험관리를 수행하고 있다. 그러나 대다수 기업에서 위험을 관리하기 위한 프로세스의 범위(영역)를 선정하는 것에는 많은 노력을 기울이지만 단위 프로세스별로 어떠한 방법(How)과 도구 및 관리기법을 사용하여 위험을 정량적으로 관리하고 완화시킬지에 대한 구체화된 노력은 미흡한 것이 사실이다. 본 논문에서는 CMMI-DEV 모델의 RSKM(Risk Management) 프로세스와 PMBOK(Project Management Body of Knowledge, 4th Edition)의 위험관리 지식영역(Knowledge Area)을 프로세스의 지속적인 개선을 위하여 PDCA(Plan-Do-Check-Action) Cycle의 각 단계별 목적에 맞게 통합(Integration)시켜 IT 프로젝트를 위한 개선된 위험관리 프로세스를 제안하였다. 제안 프로세스의 개선효과를 검증하고 분석하기 위하여 측정지표를 제시하였으며, 개선 프로세스의 적용 전후 결과를 정량적으로 비교 및 분석함으로써 개선효과를 도출하였다.

Some strategies for the integrated water management system based on GIS was suggested for the comprehensive and systematic management on the watershed. Contents of database and thematic layers for the related elements with GIS was indicated to estimate the quantity of total pollution loads and to simulate the water quality. Also, functions for the information providing was suggested on the connection with spatial data and attribute data, the search for collected data, the analysis for time series, and the visual presentations. Finally, it was suggested to integrate the existing systems and database structures, and to construct of data warehouse.
