이 논문은 공간 증강 현실 콘텐츠를 낮은 비용과 빠른 속도로 제작하기 위한 프레임워크를 제안한다. 우리의 프레임워크는 구하기 쉬운 장비인 웹캠과 프로젝터만으로 투영 기반의 증강현실 콘텐츠를 제작할 수 있는 환경을 제공한다. 콘텐츠 제작자는 웹캠과 프로젝터를 설치하고 프레임워크에서 제공하는 인터페이스를 조작하는 것으로 쉽고 빠르게 공간 증강 현실 기술을 사용한 디지털 콘텐츠를 제작할 수 있다. 기존의 솔루션들은 고가인 경우가 많고 콘텐츠 제작자가 증강 현실 기술을 스스로 적용하는 것이 쉽지 않기 때문에 우리가 제안하는 프레임워크는 콘텐츠 제작자가 콘텐츠 내용 자체에 집중할 수 있도록 돕는다. 프레임워크를 통해 웹캠과 프로젝터를 한 번 설정하면 인식 가능한 실제 물체의 이동과 회전에 따른 가상 물체의 렌더링 결과를 올바르게 투영한다. 그 결과, 우리는 사실적인 증강현실 콘텐츠를 확인할 수 있다.

This paper focuses on development of a testbed for analysis of robot-terrain interaction on rough terrain and also, through one wheel driving experiments using this testbed, prediction of maximum velocity and acceleration of UGV. Firstly, from the review regarding previous researches for terrain modeling, the main variables for measurement are determined. A testbed is developed to measure main variables related to robot-terrain interaction. Experiments are performed on three kinds of rough terrains (grass, gravel, and sand) and traction-slip curves are obtained using the data of the drawbar pull and slip ratio. Traction-slip curves are used to predict driving performance of UGV on rough terrain. Maximum velocity and acceleration of UGVs are predicted by the simple kinematics and dynamics model of two kinds of 4-wheel mobile robots. And also, driving efficiency of UGVs is predicted to reduce energy consumption while traversing rough terrains.

수자원시스템의 효율적인 운영 및 관리를 위해서는 하천 시설물들을 효율적으로 연계운영 할 필요가 있다. 그러나 이를 위한 시뮬레이션 모형은 최선의 대안을 보장하지 못하고, 최적화 모형은 복잡한 수계 현황을 유연하게 고려하는 데 어려움이 있다. 따라서 시뮬레이션과 최적화 기법의 한계점을 서로 보완해서 활용하는 것이 바람직하다. 이에 본 연구에서는 시뮬레이션과 최적화 기법의 원론적 비교를 통해 각 기법의 장･단점을 분석하고, 두 방법의 한계점을 극복할 수 있는 시뮬레이션 기반의 최적화 모형, CoWMOM의 활용을 제안한다. 아울러 댐-보 연계운영 모형의 활용방안으로 i) 과거의 특정 기간에 대한 분석 도구로써의 활용법과, ii) 미래 수문 정보가 불확실한 상황에서 댐-보 연계운영을 하는 현실에 적합한 모형 활용 절차를 제시한다.

Recently according to increase of enlarged scale ports in conformity with increase in over size vessels and container handling service, pollutants generated from ports are increasing. In advanced countries, reduction in carbon dioxide emission assigned to them has been implemented according to the Climate Change Convention and Kyoto Protocol from 2008 to 2012 in order to lessen carbon dioxide emission. Henceforth increase in discussion on the measure of constructing Green Port and low-carbon port is expected in our nation's field of port as well, it is considered that the effort in reduction with regard to undesirable output which causes environmental problem of analysis target during measuring effectiveness. Therefore, in this study, effectiveness was estimated through directional technology distance function considering undesirable output differently from effectiveness analysis of existing container terminal, and then performed comparative analysis with the result analyzed with BCC output-oriented model. As the result of analysis, in 2007 DMU3 and DMU5, and in 2010 DMU2 and DMU4 appeared to be efficient terminals in BCC output oriented model, and in directional technology distance function model, DMU1, DMU3 in 2007, DMU3, DMU5 in 2008, DMU7 in 2009, and DMU2, DMU5 in 2010 appeared to be efficient terminals.

In this prolonged economic recession, the countries in Northeast Asia play a crucial role in the global market and the relationship between Korea and China gets more attention due to its significant achievement during the past 20 years after the establishment of diplomatic ties in 1992. In this regards, this study presents general overview of Korea-China Car Ferry Route and evaluates the efficiency level of each operating route using DEA model. Incheon-Yingkou, Incheon-Lianyungang, Pyeong Taek-Lianyungang are analyzed as efficent routes, while from the view point of passenger efficiency, 4 routes i.e, Incheon-Dalian, Incheon-Dandong, Pyeong Taek- Weihai, Gunsan-Shidao are also noted as efficient routes. Consequently, other inefficient routes can benchmark these efficient routes by increasing cargo volume and passengers.

In this study, the strategies to achieve more efficient management for the sea-crossing bridges were prepared considering their current maintenance status and special structural characteristics. Various ideas were suggested based on the professional experiences and several knowhow accumulated in the field of the bridge maintenance. Also, such ideas were systematically classified and defined with several sub-topics through the techniques used in the value engineering. In order to improve the management efficiency, the detailed plans considering the sub-topics were established

This study aims to investigate basic requirements for adopting the Building Information Modeling(BIM) technology to CO2 monitoring system of building maintenance. This study is progressed to emphasis to utilize BIM building information to estimate amass of CO2 on the maintenance stage. The main purpose of this monitoring technology suggest the effective use of information which enable to efficient evaluation technology.

The purpose of this study is to evaluate the effectiveness of the way-finding system on the facility management in the general hospitals. For this purpose, visiting survey and questionnaire study are carried out for four general hospitals. Based on the results, way-finding system such as sign board is a essential element for patient satisfaction as well as facility management.

For the purpose of evaluating the eco-efficiency(EE) on surplus heat generated from industrial process, techniques of life cycle assessment are adopted in this study. Because it can be indicated both environmental impacts and economic benefits, EE is well known as a useful tool for symbiosis network on the sustainable development of new projects and businesses. To evaluate environmental impacts, the categories were divided into two areas of resource depletion and global warming potential. It can be seen that environmental impact increased a little but much higher economic benefit on the company, environmental performance and economic value were improved on the apartment by the district heating, respectively. In result, eco-industrial park(EIP) project on surplus heat should be found sustainable new business because the EE was in the area of fully positively eco-efficiency and, moreover resource depletion was taken place than the reduction of greenhouse gas.
