Today, information technologies have been applied to operations in container terminals, and it is possible to collect operational log data due to development of equipment and operations technology. Terminal operators are collecting event log data and try to figure out the way of resolving operations problems. Operators want to analyze event logs to determine the causes of the operation problems, but it can hardly be done manually. In this paper, we suggest a formal framework to evaluate performance measures using the collected log data of operations in container terminals. The proposed formal framework supports different container terminal layout, operational processes, and equipment. Our formal framework is composed of specification of terminal layout, log data, workflow, statistics, and report, based on the concept of container handling objects. For validation of our framework, we have implemented a terminal performance analysis system based on the proposed framework.

IT investments of hospitals are growing exponentially and various information systems such as OCS (Order Communication System), EMR (Electronic Medical Record), PACS (Picture Archiving and Communication System), ERP (Enterprise Resource Planning) have been implemented at a number of hospitals in Korea. We have surveyed and analyzed the current status of hospital information systems of major hospitals in Korea, and proposed an information strategy for e-Hospital implementation. Firstly, implementation status of major subsystems of HIS such as OCS, PACS, and EMR has been surveyed and types of IT personnel management have been examined. Based on the field survey result, an information strategy for e-Hospital implementation has been proposed, that can be referenced by hospitals to build their own information strategy. We expect that the study result can contribute to understanding the present status and issues of HIS and information strategy planning of hospitals.

Due to the rapid developments in information and computer technology, the warfare paradigm is being transformed into information-centric and knowledge-based warfare. This atmosphere may have significant impact on the ROK armed forces' Force Improvement Plans (FIP) which is documented in 'Defense White Paper 2004'. We focus here on the relationship of information-centric force and deterrence of invasion. Particularly, we are interested in understanding the level of information superiority that might be required to deter the invasion. In order to solve this problem, we employed two-sided, zero-sum strategic game to simulate the outcome with six hypothetical cases devised by varying the level of information superiority.

This paper is to aimed to design a model of Korea defense information resource management structure from the viewpoint of system's approach, especially focusing on planning/programming procedures, organizational structure and business process re-engineering. The author analyzed current projects and plans on the field of Korea defense information systems, for finding what kinds of problems and why the problems occurred. The author concluded that many problems came from wrong approach of previous information resource management. Highlights of the proposed model are as follows: 1) Planning and programming structure must be considered as a major information resources and it must be managed as a key role through the whole system life cycle; 2) Organizational structure should be properly set up for managing and implementing information system projects; 3) Business process should also be analyzed thoroughly for re-engineering and innovating current inefficient organizational structure. These three additional viewpoints added to previous model for improving Korea defense information resource management.

3D-based BIM(Building Information Modeling) technologies can be utilized effectively as a means of systematic management of facility information for safety assurance and effective maintenance of waterworks facilities. In this study, BIM models of water treatment facilities that can be used as basic data for BIM-based maintenance of waterworks facilities were developed. Information exchange and generality of the developed BIM models were evaluated by conducting interoperability analysis of IFC(Industry Foundation Classes) conversion models. In addition, the application of COBie(Construction Operations Building information exchange) was recommended as an effective countermeasure to deal with technical limitation regarding exchange and utilization of facilities-related information through current IFC models. The results of this study can contribute to the development of BIM-based maintenance system for waterworks facilities.

Exact and rapid acquirement of ocean environment information is going to become more of an indispensable source of naval operations. Ocean surface measurements using High Frequency (HF) radar, which covers about 10-220km and has spatial resolution of 0.3-12km, have being operated in our country. It remotely observe and transmit realtime sea surface currents and waves. In the near future, the HF radar systems will be established along the whole coastal area. A performance of network of HF radar will support various marine and naval activities. Operational uses of HF radar for enhancing naval operation ability are suggested.
