As commonly known, The U.S. Army Corps of Engineers, made up of approximately 35,000 engineers, is the premier public construction organization in the world. The Corps, the world-wide and unique organization, has the multi-functions like civil works projects, water resources management, environmental protection, disaster response as well as military construction. To meet national and military requirements , the Corps has developed various systems. As the key systems, the PMBP (Project Management Business Process) is an innovative way to solve increasingly complex problems and then to achieve the Corps’ vision.and Partnering system and Construction Quality Management for Contractor , developed by UASCE, also are the significant construction management tools in worldwide. Many Korean construction contractors have verified their high constructability in the overseas. On the contrary, they can’ t meet the customer’ s needs sufficiently in the country and the reason may be caused from the absence or inadequate project management system. Therefore, this article provides the overview of the USACE and partnering system and lays emphasis on the USACE’ s CQM system. The desirable way to meet the customer’ s needs in projects should be mainly aimed at systematic business process. Some future-oriented suggestions to improve the construction quality management conclude this article.

The purpose of this study is to analyze teachers' questioning patterns in EFL classes, and propose a new set of classification based on the interaction flow that a question initiates and the teachers' intention of questions in language classroom. Data were collected from five advanced EFL classes. Six categories of teacher questions were observed and two types of interactions following the initial questions were found. The interactions were usually opened by the teacher, which confirmed the general conception, and the types of interactions were mostly chosen by the teacher's preference and the activity the class was doing.

Even though Companies have used to focus on maximizing the facility rates of operation to enhance their competitiveness and increasing employees' productivity to accomplish the price and quality control, they no longer can make their business successful in these days. To be successful in increasingly competitive environment, it is essential to capture customers' needs and to reflect customers' needs in their production scheduling system. This paper describes that manufacturing scheduling method using TOC in SCM environment to change companies-oriented manufacturing scheduling to customer-oriented manufacturing scheduling.

In this regard, the newly focused logistics information system makes reducing the expenses of whole logistic available by cutting down the expenses of materials, transportation and stock and also, it allows the company to cut down the procurement expense through the reduced lead-time and rationalize producing plans by eliminating the uncertain orders and fluctuation in procurement. It further more optimizes the efficiency of over all productions by meeting the dead line for delivery to the customers. In the recent environment of globalization where fierce competitions exist between manufacturers, logistics plays important role in the strategies of companies, and managements of companies try their best efforts in establishing the strategy to accomplish the innovative relationship between supply chain channels. Therefore, in this study, we try to suggest the model of consolidated logistics system that is integrated logistics information system with suggesting the better way of logistics and comparative analysis with logistics system to resolve the difficulties numbers of companies face after realizing what logistics information system is in Korea.

The purpose of this study is to improve convergence speed of topology optimization procedure using the existing ESO method and to deal with topology decision of the truss structures according to a boundary condition, such as cantilever type. At the existing ESO topology optimization procedure for the truss structures, the adjustment of member sizes according to target stress has been executed by increasing or reducing a very small value from each member size. In this case, it takes too much iteration till convergence. Accordingly, it is practically hard to obtain optimum topology for a large scale structures. For that reason, it is necessary to improve convergence speed of ESO method more effectively. During the topology decision procedure, member sizes are adjusted by calculating approximate solution for member sizes corresponding to the target stress at every step, the new member sizes are adjusted by such method are applied in FEA procedure of next step.
