The purpose of this review of literature is to investigate what kinds of research have been done on social construction of mathematics understanding among elementary students in small groups. Only empirical studies were reviewed, and then grouping was done in terms of the purpose of the study. This grouping identified three categories: 1) Social and mathematical norms in mathematics classroom, 2) Teaching productive communication behaviors for active learning in small group, and 3) Participation roles and communication behaviors in different group structure. To enhance social construction of mathematics understanding in small group settings two suggestions are made: the importance of the selection of collaborative tasks or problems and teachers' beliefs about mathematics and the teaching an learning of mathematics.

Efficient communication of construction information has been critical for successful project performance. Building Information Modeling (BIM) has appeared as a tool for efficient communication. Through 3D CAD objects, it is possible to check interception and collisions of each object in advance. In addition, 4D simulation based on 3D objects integrated with time information makes it realize to go over scheduling and to perceive potential errors in scheduling. However, current scheduling simulation is still at a stage of animation due to manual integration of 3D objects and scheduling data. Accordingly, this study aims to develop an integrated model of 3D CAD objects that automatically creates scheduling information.

Construction CALS has contributed much to the improvement of construction management. Recently, the ubiquitous technology brings another opportunities for expanding tile business horizon in construction. The government policies to upgrade the information technologies in Korean offer an environment in which practical application of ubiquitous becomes more practical. To maintain the level of competitiveness, construction companies need to pay attention to the chance of ubiquitous technologies. This paper introduces the research movement in the construction industry in an attempt to find out the feasibility of ubiquitous technologies such as RFID, USN, etc. The construction process, which is executed in the natural environment, will benefit from the state-of-are information technologies in terms of improved communication interface.

The objective of this study is to propose the basic design plan of system by comparing and analyzing application environment of lift and elevator group control system, as preliminary study for the application of group control system to lifts for high-rise construction. The basic design plan is suggested in terms of group control algorithm, hall call system type, operation information recording device, information communication method, and operation method. The results of this study can be used as basic data for software and hardware design for application of group control technology of lifts for super tall building construction and ultimately contribute to improve the operation efficiency of lift for high-rise construction.

When construction engineers perform their work in the jobsite, they have to record as-built conditions in the project log (Data Collection). On the other hand, the engineers often have to refer to the construction documents when necessary at the job faces (Data Access). The practice of Data Collection and Data Access in the jobsite can be greatly enhanced by utilizing mobile computing with wireless communications. In this paper, two cases of mobile computing applications for construction field management are presented; Mobile Specifications System and Mobile Data Collection System. The demonstration of the process for developing two mobile applications is the primary purpose of the paper. The problems and issues involved with adopting mobile computing for construction field are also presented. The simple information framework for mobile computing has been also proposed as an outcome of the research. As for development tools, readily available relational database and wireless network have been used. The use of commercial mobile broadband was examined for data communication where local area network is not available.

For telecommunication system construction to minimize the casualty of fisher, we investigated the usability of TRS communication system and performance of GPS automatic position transmitter (APT) which can be utilized for the survival, search and rescue of the victims. The trial experiments were conducted at sea with TRS and CDMA in the East, West and South Sea of Korea from October to December. As a result, the usability of the TRS as an emergency communication system device was verified since it provided stable position and voice information to the boundary of 50km far from the coast. Therefore the system is expected to contribute to minimization of victims.
