Needs of automation and computerization in the construction industry has been recognized but the implementation of e-business solutions with project management systems has not been fully explored. In order to cope with different management practices in home office and project sites, integration of two popular systems, Enterprise Resource Planning (ERP) and Project Management System (PMS) is essential. The objective of this study is to find ways to functionally and systematically integrate ERP and PMS. With the integration of ERP and PMS, a project will be managed much more efficiently and effectively. It is expected that this study will benefit system integrators and help them to understand construction management processes and integrate the solutions with minimized programming work.

In the smart grid, it will be possible to communicate with the consumers for the purposes of monitoring and controlling their power consumption without disturbing their business or comfort. This will bring easier administration capabilities for the utilities. On the other hand, consumers will require more advanced home automation tools which can be implemented by using advanced sensor technologies. For instance, consumers may need to adapt their consumption according to the dynamically varying electricity prices which necessitates home automation tools. This paper tries to combine neural network and nonlinear autoregressive with exogenous variable (NARX) class for next week electric load forecasting. The suitability of the proposed approach is illustrated through an application to electric load consumption data. The suggested system provides a useful and suitable tool especially for the load forecasting.

The basic concept of an improved business and productivity for Small and Medium Sized Enterprizes, which makes use of an information portal, is to assure competitive power, increase the production quantity through the interchange of a company and the outside environment, and to build cooperation. To reduce the charge of the equipment, as well as to introduce and information program, it should build an information environment from inside the company by suing the information portal ASP(Application Service Provider). This portal is already built by the basic information infrastructure through the Internet.

We have developed Ethernet based real-time communication systems called "Vnet/IP" for DCS which is the control system for process automation. This paper describes the features and the technologies of the ASIC which is utilized in the communication interface hardware for Vnet/IP. Vnet/IP has been developed for mission-critical communications. Hence it has real-time feature, high reliability and precise time synchronization capability. At the same time, it is able to deal with standard protocols without influence on mission-critical communications. The communication interface hardware has a host interface and dual redundant network interfaces. The host interface can be chosen PCI-bus or R-bus which is the proprietary internal bus developed for the high reliable redundant controller. Each network interface is a RJ45 connection with 1Gbps maximum in compliance with IEEE802.3.

It is very important to track a complicate weld seam for the welding automation. Very recently, laser vision sensor becomes a useful sensing tool to find the seams. Until now, however studies of welding automation using a laser vision sensor, focused on either image processing or feature recognition from CCD camera. Even though it is possible to use a simple algorithm for tracking a simple seam, it is extremely difficult to develop a seam-tracking algorithm when the seam is more complex. To overcome these difficulties, this study introduces a simulation system to develop the seam tracking algorithm. This method was verified experimentally to reduce the time and effort to develop the seam tracking algorithm, and to implement the sensing device.

Tissue culture, or micropropagation , is being used for the vegetative multiplication of several hundred millions of superior plants annually for horticulture and forestry. It is often more expensive than other forms of propagation using cuttings or seeds, because it is labor intensive and more specialized . The aim of automation is to reduce the cost per plantlet by reducing labor input, and finally, to yield profit, as business activity . Labor usually account for 70-80% of th ein vitro and ex vitro cost. This paper aspects of tissue culture automization , such as technical and economical approaches in view of automization.

The automation technology is able to enhance the business process more rapidly and effective. Open BIM technology which supports automation technology of building overcomes the limitations of two dimensions drawings system. The purpose of this study is on the development of open BIM based modules for creating and verifying the core model for super-tall building in the schematic design phase. The module is expected to create cases of core models automatically and it is expected to verify the requirement of building model. This module is anticipated to utilize for creating the core model rapidly in order to create the alternative plan and to make the model accurate by its verification.

Substation Automation System (SAS) based on IEC 61850 is becoming more and more reality in applying power systems. As well, the development of various engineering tools and the convergence with diagnostic systems are underway. To reflect recent advancements in SAS technology, the Korea Electric Power Corporation initiated a 154kV SAS pilot project and a smart power grid business in 2010. In this paper, the authors will summarize the overview and the lessons learned in applying the IEC 61850-based 154kV Main transformer bay IED solutions to these two project.

Construction firms attempt to improve project performance by adopting technology. However, the advantages gained from technology utilization are still not clear. Lack of information regarding technology benefits has resulted in industry reluctance to implement new technology. Therefore, there are needs for studies that quantify the impacts of technology utilization on project performance. An industry-wide survey was used to collect project data from 70 capital facility projects on the issue of technology usage and project owner satisfaction parameter. This paper reports on integration/automation technology usage in the Taiwanese construction industry and associated impacts on project owner satisfaction. In addition, integration and automation technology findings are presented by project phase. The analyses indicate that projects with owner satisfaction have, on average, higher levels of technology utilization than projects with owner dissatisfaction for all technology usage metrics analyzed.

At the point of increasing concern on EDI (Electronic Data Interchange) and on related trade automation, a research of trade enterprises' EDI system adoption and using has a very significant meaning to get the roots of the problems and to put the practical use. After studying the outline of EDI and it's proceeding state, this thesis tries to point out some problems of them and presents the reform measures in the aspect of a legal and business aspect. According to the results of this study, the argues and their control suggestions are as follows. First, the process of trade relations and the it's public concept on the EDI should be changed to the agreement of the adopting and using the standard EDI in Korea. Second, the financial and tax support is needed to the following; the reconsideration of each enterprise, the inrestment of enterprises' role for the training their professional human resource and goverment and related organization's guiding role. Therefore, to maximize the effects of EDI after solving the issues. above trade process the issues should be unified by coorperation with the goverment and related organizations for the information circulation side and considered that EDI system have to positively make automation of trade on the basis of suggestions above.
