This study has described the case that has been experienced personally by centering on discords created in railway construction projects while performing practical duties at the construction field. Accordingly, as seen from the experience of performing one method called discord reconciliation conference, it seems that there are many parts to be improved on for the particular details because the conference was progressed by the position of a non professional in its content or procedure. But as seen from the word origin called "discord", looking at the state of finding one solution after another from vagueness of solving difficult and entangled problems, we could sense that the sincere communication and honesty was more progressive method in the phase of looking for one solution after another. Although this essay was centered on a typical case of railway construction project, I hope for it to spread throughout the whole society and especially hope that many discords created in public work sites such as public works would become settled smoothly between the parties concerned.

Currently, the process of selecting products such as construction materials and equipment in the design phase proceeds based on the reuse of products used in the previous projects or samples from design companies as well as information on the limited products provided from the website of several manufactures. In particular, it is urgently required to formulate a standard product information management system that can be utilized in the BIM-based design environment these days. In Korea, domestic construction information classification system was developed, but its utilization has been underestimated since continuous studies on the practical usability are still lacking. Therefore, this paper derived problem of domestic construction materials information system by comparing with abroad material information system. Issues and implication is derived in terms of (1) Input information (2) Provide information, and (3) Utilize Information.

Because it is now the fourth year since the first operation of the departmentalized classroom system in March 2010, a clear analysis of the conditions for the system from the investigation of the schools' operating the system is necessary. In particular, in-depth investigation and analysis are pressing, because investigation and observation of the conditions and situations for the departmentalized classroom system are not conducted continuously after creating an environment for the management of the system through a large investment. Therefore, the purpose of this study lies in building clear data on the conditions for the operation of the departmentalized classroom system in schools by visiting schools that operate the system, grasping the conditions for environmental composition, and investigating and analyzing practical use of the environment.

The proliferation of real-time multimedia services requires huge amounts of data transactions demanding strict quality-of-service (QoS) guarantees. Multicast transmission is a promising technique because of its efficient network resource utilization. However, high head-of-line (HOL) blocking probability and lack of service-specific QoS control should be addressed for practical implementations of multicast networks. In this paper, a topology aware fanout set division (TAFD) scheme is proposed to resolve these problems. The proposed scheme is composed of two techniques that reduce HOL blocking probability and expedite packet delivery for large-delay branches regarding multicast tree topology. Since management of global topology information is not necessary, scalability of the proposed scheme is guaranteed. Mathematical analysis investigates effects of the proposed scheme and derives optimal operational parameters. The evaluation results show that the TAFD scheme achieves significant delay reduction and satisfies required delay bounds on various multicast networks.
