The study figures out the alternatives of training BIM design experts which is the biggest obstacle in training manpower of professional BIM designer, the largest problem when the plant introduce BIM design about the change in Construction Environment by Equipment Based BIM Design in reality of design followed by equipment based BIM design, education institution plan. BIM is the system which is built to make these information be used easier and technique which enables design construction and maintenance in 3-dimensional virtual space by designing buildings in 3-dimensional space, and by data-basing the generated information of every life-cycle information. As the essential contents of the study, educational institutions with the public authority should invest the opening of educational programs, recruit of experts and development of textbooks from a long-term perspective. And also, the role of public institution is important above all for the development of construction industry.

Sensor nodes depend on batteries for energy source in Wireless Sensor Networks (WSNs). Low Energy Adaptive Clustering Hierarchy (LEACH) is a representative cluster-based routing protocol designed to ensure energy use efficiency whereas the virtual cluster exchange routing (VCR) information only with its closest node to build a network. In this paper, a protocol scheme was proposed wherein member nodes are designed to compare the currently sensed data with the previously sensed one and to switch to sleep mode when a match is achieved. The design is to help improve the transmission energy efficiency too.

Presented is a Genetic Algorithm(GA) for dynamic partitioning an ATM LANE(LAN Emulation) network. LANE proves to be one of the best solutions to provide guaranteed Quality of Service(QoS) for mid-size campus or enterprise networks with a little modification of legacy LAN facilities. However, there are few researches on the efficient LANE network operations to deal with scalability issues arising from broadcast traffic delivery. To cope with this scalability issue, proposed is a decision model named LANE Partitioning Problem(LPP) which aims at partitioning the entire LANE network into multiple Emulated LANs(ELANs), each of which works as an independent virtual LAN.

In this paper we describe techniques for the automated creation of geometric correct 3-D models of the building using two 2-D laser scanners. One of the laser scanners is used for position estimation using a scan matching algorithm, while the other is used to build 3-D models of the facade of the buildings. Those models can be used for virtual reality, tele-presence, digital cinematography and urban planning applications. Results are shown for building models in our campus using real data acquired from two sensors.

본 연구는 OpenGL을 이용하여 3차원 그래픽으로 가상캠퍼스 맵을 구현한다. 매핑 효과, 블랜딩 이론등을 적용하여 사실적인 물체를 구현하는 것을 목표로 한다. 매핑 효과는 조금 더 사실적인 캠퍼스 모습을 보여준다. 그리고 가상캠퍼스에 사용될 지형지물은 그래픽 기법과 블랜딩 이론을 적용하여 구현함으로써 구조를 보여준다. 본 논문은 데이터의 용량과 랜더링 시간을 줄이고, 전체적인 향상을 위한 알고리즘을 개발하는데 중점을 둔다.

다양한 사물인터넷 장치 환경간의 응용 프로그램의 플랫폼 독립성을 지원하기 위해 가상기계 기술을 사용할 수 있다. 그러나 사물인터넷 장치 환경은 가용 메모리가 한정적이므로 사물인터넷 환경에서 가상기계의 동작이 가능하게 하려면 적은 메모리를 사용하도록 경량화해야 한다. 본 논문에서는 경량의 가상기계를 설계하여 가용 메모리가 적은 저성능 사물인터넷 기기에서도 동작할 수 있게 하였다. 또한 가상기계를 구조적으로 설계하여 다양한 사물인터넷 장치의 성능에 따라 적합한 구성으로 이식할 수 있다.

Dynamic analysis of an embedded single-walled carbon nanotube (SWCNT) traversed by a moving nanoparticle, which is modeled as a moving load, is investigated in this study based on the nonlocal Timoshenko beam theory, including transverse shear deformation and rotary inertia. The governing equations and boundary conditions are derived by using the principle of virtual displacement. The Galerkin method and the direct integration method of Newmark are employed to find the dynamic response of the SWCNT. A detailed parametric study is conducted to study the influences of the nonlocal parameter, aspect ratio of the SWCNT, elastic medium constant and the moving load velocity on the dynamic responses of SWCNT. For comparison purpose, free vibration frequencies of the SWCNT are obtained and compared with a previously published study. Good agreement is observed. The results show that the above mentioned effects play an important role on the dynamic behaviour of the SWCNT.

In this paper, we developed the cyber campus which is a internet based virtual education system. This system is designed by using the client/server architecture and server push mechanism. The basic design tool is mini SQL and PERL for design and implementation. Developed system is tested on the site of Honam university(cybercam.honam.ac.kr) and confirmed its performance. This tool will be very useful as a distance education method for every school and educational agency under the internet environment.

Today, the amount of energy consumption in the university campuses is huge. The effort for the energy consumption reduction in university campuses is certainly needed by the following reason; first, contribution to the greenhouse gas discharge reduction demand. Second, energy cost reduction in university campus. Third, contribution to the improvement of the social awareness as the maximum higher educational institutions. The energy consumption analysis of current situation has to be executed for the energy consumption reduction in university campus. The energy reduction possibility in which it exists in university campuses can be understood through the energy consumption analysis. And the application is possible as fundamental data of the policy establishment for the effective energy reduction in university campuses. Especially, the best way to reduce the energy consumption in university campuses that is the energy consumption reduction of buildings. Accordingly, this study derived the plans for improving the performance of energy in the university building by analyzing case study, so this study analyzed the performance of energy for the university building through VE, a program for the analysis of building energy. Based on this result, this study classified the plans improving the efficiency of energy in university building into the plan for passive control and active control respectively, and suggested some concrete plans, and finally evaluated the performance of decreasing energy consumption for each plan.
