In the construction industry, IT has been an alternative for the enhancement of productivity and technical advances through a paradigm shift. While it has been recognized that the IT system will have a substantial influence on the industry, a quantitative valuation has been very limited. This paper has chosen EVMS (Earned Value Management System), which supports the integrated management of cost and schedule by utilizing IT tools, and which is the largest trend in the construction IT industry in Korea, in order to suggest an analysis model for the valuation of IT. The CVM (Contingent Valuation Method) is used to quantitatively measure intangible value of IT application. Then, a valuation and analysis model were suggested for the quantitative valuation of the effect of IT adoption. In terms of willingness to pay for EVMS, the expected benefits from the adoption of EVMS were US$ 584.52 per man annually. This research should be helpful for construction companies evaluating their investment to Project Management Information System.

A 16-bit computer system, called X77, is designed and constructed using bit-slice micro-slice microprogrammable. A cross-assembler/simulator software has been implemented and used to debug the entire system design including actual microcodes prior to hardware realizations. Prototypes of X77 CPU, I/O processing subsystem and their interconnections have been constructed and are in the process of being debugged.

The objective of this paper is to propose a conceptual framework of a BIM based collaboration supporting System, called Construction Project Life Cycle Management (CPLM). The framework of CPLM is proposed by reflecting the characteristics of the AEC industry such as deliverly methods, process, fragmentation, etc.. And it is a system intended to help project participants make better decisions and to facilitate coordination between various stakeholders in a project by providing virtual collaboration environment.

The mission of tilting train development project is enhancing the speed of transportation of railway passenger using existing infrastructure. The threat of this project is the tilting technology is newly incorporated to this project. To overcome the threat this project incorporate systems engineering technology to development tilting train system. The systems engineering process, which was used in this project, was performed in accordance with systems engineering standard EIA632. This paper shows the systems engineering technology which was used to develop the tilting train system specification. This paper also shows the requirement template which was developed to communicate and synthesis various specialty engineering.

This article deals with an economic evalutation of the 'Pasture Project of Kum River', which is the farming plan of mitten crabs in a stream of it. An augmented model of social capital is based on the past ecological-economic system dynamics model and elaborated further with suggestions of social capital literature. During the modeling process a chain diagram of causal relations and its relevant mathematical equations are presented for simulating the project performance, and the simulation results are provided to contrast the dynamic behaviors of the former ecological-economic model with ones of the new model incorporating social capital. The results indicate that an increase in the economic benefit of the project could happen in case of considering the process of social capital accumulation around the case area, which can be regarded as a remarkable trial to approve the common confidence in the role of social capital to enhance an economic achievement.

Due to the increasing importance of technology development project evaluation, many evaluation methods have been developed. However, most project evaluation methods are not directly applicable for evaluating performance improvement projects in a manufacturing system. It is due to the fact that the existing project evaluation methods do not deal with the performance evaluation of the system. This paper deals with performance measurement model of a manufacturing system based on decomposition method and evaluation method for technology development project based on options thinking. A case example is discussed to illustrate the process of the proposed evaluation method.

ERP is a topic of currency in MIS circle. Numerous organization have developed their information systems using many kinds of ERP packages such as Oracle, SAP R/3, uniERP, etc. However, the pricing methodology of ERP systems is not yet established in a proper way. This paper attempts to investigate factors influencing the price of ERP system. Thirty eight ERP consulting firms participated in this research project. Based on the data from ERP consulting firms, price of ERP systems basically consist of package cost, consulting fee, and customizing expense. The results of this research project are finding factors affecting above three parts that consist price of ERP system. This paper found that factors influencing package price are number of modules, number of users, the degree of package reliability. The factors affecting consulting fee are the degree of project specialty, level of consultants. Finally the factors influencing customizing cost are the degree of project difficulty, project time.

The high power RF system for the PEFP 20MeV proton accelerator composed of the 3MeV RFQ and the 20MeV DTL has been installed. The klystron for the RFQ was tested up to 600kW and operated routinely to drive the RFQ in a pulse mode operation. The klystron for the DTL which consists of 4 tanks was tested up to 800kW in pulse mode operation. The pulse width and repetition rate was 50${\mu}s$ and 1Hz respectively. The high power RF system has been operated to drive each accelerating structure and will be used to accelerate 20MeV proton beam.

This paper presents an integrated real-time monitoring and control framework that facilitates decision making by enabling project managers to take corrective actions right after any deviation happens and mitigate the damage to the ongoing steel projects. The proposed framework employs the High Level Architecture (HLA) as its infrastructure. It is composed of several individual monitoring and control components called "Federates," which cooperate and interact with each other through the Real-time Infrastructure (RTI). Reusability, interoperability and extendibility of federates in the proposed project control system make this a unique system.
