Railroad geotechnical information management system was developed by using Web GIS and DB in this study. The standardization of railroad geotechnical information is progressed by classifying three groups as like basic informations, vibration informations along railway lines and design drawings. The basic informations consisted of basic and dynamic properties of soils, geophysical exploration and seismic survey/exploration. And the specification for 'human exposure to whole-body vibration' was adopted to construct the vibration informations along railway lines. The informations as like drawings and photographs were saved by changing to graphic files in the standardization of design drawings. In the case of standardization of geographical information, the topographical maps(NGIS, 1:5000) were primarily used as digital maps. Another digital maps(KRRI, 1:5000) and their geographical DB based on NGI code system were added on this maps. The standardized informations were used to construct their database. And railroad information management system was developed using Entity-Relation(ER) model which had a good feasibility for expansion and transition to other system in designing stage of database. This system consisted of layer selection, search and analysis of geotechnical informations and Zeus DB was adopted for GIS operating and user interface. This system could be a good tool for saving, searching and analyzing the geotechnical and geophysical informations. These DB systems would offered the basic informations to plans, design and construction of railroad lines etc. in practical use.

Recently, with the rise of environmental issues and the change of government policy (Renewable Energy 3020 Implementation Plan), a large amount of renewable energy such as solar and wind power is connected to the power system, and most of the renewable energy is concentrated in the power distribution network. This causes many problems with the voltage management and the protection coordination of the grid due to the its intermittent power generation. In order to effectively operate the distribution network, it is necessary to deploy more intelligent terminal devices in the field to measure the status of the distribution network and develop various operation functions such as visualization and big data analysis to support the power distribution system operators. In addition, the failover technology must be supported for the non-stop operation of the power distribution system. This paper proposes the system architecture of new power distribution management system to cope with high penetration of renewable energy. To verify the proposed system architecture, the functional unit test and performance measurement were performed.

In order to boost productivity and efficiency of architectural design, architect accumulates materials and details which are repeatedly used. According as introduction and application of BIM (Building Information Modeling) have proliferated, a number of data are being produced. BIM data constructed in a stage of architectural design reduces repetitive works of design and can be used in estimate and construction, maintenance. BIM library gathered these data are able to enhance participants collaboration and design improvement. Library is a vital factor in BIM and a number of libraries are needed as BIM introduction and application have proliferated in architecture industry. However, BIM Library establishment and related research development are incomplete. And specific standard setting and institutional environment for BIM library building have not been achieved. As such a vast amount of information are generated but there is no systematic plan and reuse frequency is low. So it is necessary to build system for effective data sharing and operation management. In this study, through establishment of BIM standard system and construction of management environmental system, it has an object in view for developing framework which can efficiently manage various libraries happened in BIM architectural design field.

SNMP(Simple Network Management Protocol) could have the overhead of network, if the number of the agent system which is managed by the management system is increased by the polling for the collection of network management information and the reply traffic for it. In this Paper, the polling method used in SNMP is improved, and Group Polling method is proposed. This can reduce the overhead of network, on case that the agent system is to be increased. The proposed method collects information by grouping agent systems, and have smaller reply latency time and communication overhead than the previous method. So if the number of agent system or the Polling count is numerous, the proposed method is more efficient. As the result of the prototype test, the increasement of agent system can have small variation of traffic and transmission delay time.

Web based integrated sewer management system was developed for the analysis of sewer flow and for the optimal operation of sewer works using ArcView and SWMM. SWMM and ArcView were dynamically linked together using Avenue in order to construct user-friendly information management system. The developed system was applied to the residential area in Choonchun city to verify its utilities. All the relevant field data were analyzed on the basis of the developed system, and the modeling of sewer flow was implemented using RUNOFF, EXTRAN, TRANSPORT in SWMM. This system is now in the process of connection to the management system of stormwater, surface and subsurface environment in order to develop an integrated environmental management system. Futhermore, this system will be a critical part of overall control system of sewer works including sewer network and wastewater treatment plant. As this system can provide comprehensive prediction of flow and pollution profiles, it could serve as a tool not only for the optimal management, but also for the decision support system to examine the efficiency of planning and implementation of sewer projects.

In this paper, we describe about the user terminal tagging-based embarkation/disembarkation management system and embarkation/disembarkation management method using this system. The system authenticates the validity of the user and on whether to board on the ship by tagging the user's terminal which the boarding reservation was made by using the management terminal provided in the ship. The system identifies on whether the user disembark in the ship by tagging the user's terminal. In the event of ship accident, it is easy to figure out the user and manage the non-contact boarding and disembarking. Therefore, we design the embarkation/disembarkation management system based on user's terminal tagging on the terminal provided in the ship and embarkation/disembarkation management method using this system. User terminal tagging can solve the problem of manpower required for the management of embarkation and disembarkation, the problem of requiring time to confirm the match between the reservation and the passenger, and the problem of increase of the possibility on the spread of infectious diseases due to face-to-face contact.

To support the establishment of Information Security Management System, the private sector and the public sector have taken some measures. In the private sector, KISA(Korea Internet & Security Agency) has certified ISMS system based on "The Act on Communication Network Use Promotion and Information Security etc.". In the public sector, No authentication system has been established. Instead, NIS(National Intelligence Service) has enforced 'Information Security Management Condition Evaluation' based on "Electronic Government Act". This article compared ISMS control parts of the private sector with that of the public sector and analyzed the non-enforcement parts of ISMS implementing two sectors for years. Based on this, I would like to consider the method of establishment for efficient ISMS.
