「Finite Element Modeling and Simulations of Heteropotopic Ossification Followed Cervical Disc Total Replacement Surgery」
Prof. Ganbat Danaa, Department of Technical Mechanics, School of Mechanical Engineering and Transportation, Mongolian University of Science and Technology (MUST), Mongolia
 Heterotopic ossification (HO) is one of the potential complications following cervical total disk replacement. We hypothesized that heterotopic ossification formation is related to external loading in the spinal vertebrae after total disk replacement. Two different finite element models are developed: (1) A two-dimensional finite element model of a cervical vertebra treated by total disk replacement in the sagittal plane; (2) A three-dimensional finite element model of TDR on the C5-C6 segment.
HO formation was predicted by simulating a bone adaptation process under various physiological mechanical loadings. The distributions of strain energy on vertebrae were assessed after HO formation.
Different types of heterotopic ossification formation were analyzed according to the directions of forces.

「A Development of Revision Control Framework For 3D CAD Model Data」
Assoc./Prof. Nyamsuren Purevdorj, Department of Technical Mechanics, School of Mechanical Engineering and Transportation, Mongolian University of Science and Technology (MUST), Mongolia
    A web-based calculating and representing differences between 3D CAD models is an important and challenging task in distributed, collaborative and integrated design areas. Many CAD application developers have improved user interfaces and connectivity supports that enable the incorporation of online information and web applications in a convenient manner. The representing difference involves numbers of steps such as uploading 3D model data file to the STL converting server, calculating their differences and visualizing them on the webpage. This presentation describes steps in involved web based revision control system supporting most of CAD native formats.

◆12:00〜12:30
「Influence of mountain circulations on urban meteorology」
Dr. Gantuya Ganbat, City University of Hong Kong, Hong Kong
    More than half of the World's population lives in urban areas despite the urban areas only cover 0.2% of the Earth's land use surface. Urbanization impacts weather and climate. When cities are located in and/or near mountainous areas, complex local atmospheric circulations are interacted with each other. Numerical modeling and theoretical approaches are applied to study the influence of mountain circulation on urban meteorology, the interactions of the local circulations, and the dependences of the local circulations to several factors. Also, the local circulations in the presence of temperature inversion, an important aspect for air pollution in mountainous urban areas, are studied.
