The purpose of this paper is to develop a framework for construction knowledge management. Three variables of proposed framework includes knowledge class, strategic business function, and engineering data form. Several different techniques for evaluating the variables are developed in order to develop a strategic action plan for engineering knowledge management systems. The proposed framework for an action plan will contribute to develop knowledge management systems related to strategic engineering functions for construction companies.

The development of mobile applications is fast in recent years. However, nearly all applications are for messaging, financial, locating services based on simple interactions with mobile users because of the limited screen size, narrow network bandwidth, and low computing power. Processing an algorithm for supporting a group decision process on mobile devices becomes impossible. In this paper, we introduce the mobile-oriented simple interactive procedure for support a group decision making process. The interactive procedure is developed for multiple objective linear programming problems to help the group select a compromising solution in the mobile Internet environment. Our procedure lessens the burden of group decision makers, which is one of necessary conditions of the mobile environment. Only the partial weak order preferences of variables and objectives from group decision makers are enough for searching the best compromising solution. The methodology is designed to avoid any assumption about the shape or existence of the decision makers' utility function. For the purpose of the experimental study of the procedure, we developed a group decision support system in the mobile Internet environment, MOBIGSS and applied to an allocation problem of investor assets.

Software architecture allows us to make many decisions about a software system and analyze it even before it exists in order to make systematic and planned development possible. Similarly, architecture-based software evolution planningmakes planned evolution possible by allowing us to make many decisions about evolution of a software system and analyze its evolution at the level of architecture design before software evolution is realized. In this paper, we develop a framework for architecture-based software evolution planning for the class of deterministic evolution plans by defining and relating various essential concepts and developing its valuationmechanism so that a plan with the greatest value among candidate plans can be selected as an optimal plan. A case study is conducted for explicating the framework and exemplifying its usage.

IT convergence and integration technology aims to create new synergies by combining IT related technology and performance. This study conducted a basic research for combining construction and IT technology to create new synergies. Specifically, the purpose of this study is to combine USN and GIS technology and then apply it to urban facilities management. For this, we have developed the USN hardware, tested propagation communications, and made the GIS Algorithm and a system. Existing sensor node allocation method is mostly to install in a random way or with in-situ survey, but the problem with this method is contradictory to cost effectiveness and efficiency. To solve this problem, we developed a new method for sensor allocation. Using this method, the USN technology could be applied in the range of city unit. This technology can be applied to the ubiquitous urban development such as U-City and Smart City.

Recently, three-dimensional (3D) GI (Geospatial Information) using LiDAR system has been used various fields such as the production of digital map, the modeling of 3D building and urban area, and analysis of communication network and environmental effect. In this study, the production cost of digital map by aerial LiDAR surveying were compared with the cost by aerial photograph surveying for analysis of economical efficiency. It is expected that the results of this study will be used base data for production, update, revision of digital map and curtail effect of national budget.

Recently, Financial companies implement DLP(Data Leaks Prevention) security products and enforce internal controls to prevent customer information leaks. Accidental data leaks in financial business increase more and more because internal controls are insufficient. Security officials and IT operation staffs struggle to plan countermeasures to respond to all kinds of accidental data leaks. It is difficult to prevent data leaks and to control information flow in business without research applications that handle business and privacy information. Therefore this paper describes business and privacy information flow on applications and how to plan and deploy security container based OS-level and Hypervisor virtualization technology to enforce internal controls for applications. After building security container, it was verified to implement internal controls and to prevent customer information leaks. With security policies additional security functions was implemented in security container and With recycling security container costs and time of response to security vulnerabilities was reduced.

The multi-layer neural network that has broadly been utilized in designing the controller of robot manipulator possesses the desirable characteristics of learning capacity, by which the uncertain variation of the dynamic parameters of robot can be handled adaptively, and parallel distributed processing that makes it possible to control on real-time. However the error back propagation algorithm that has been utilized popularly in the learning of the multi-layer neural network has the problem of its slow convergence speed. In this paper, an approach to improve the convergence speed is proposed using the fuzzy logic that can effectively handle the uncertain and fuzzy informations by linguistic level. The effectiveness of the proposed algorithm is demonstrated by computer simulation of PUMA 560 robot manupulator.

Hospital information system has been widely used and increased recently for a variety of many aspects. And Order-Communicating system(OCS), as like as hospital information system, has been used in many medical care facilities, which is simple and easily accessible, useful system. Also then the use of OCS in emergency care center in YUMC has been introduced since 1996. 10, above 70% of availability is noticed at present and increasing in the use rate, is considered that it is very simple and accurate, time-saving, widely applicable system. So authors say that, after the use of OCS in emergency care center, interhospital exchange of the patient's information and also accomplishment of EMSS can be possible.
