  • Recently, there are growing interests in building LCCO2 Assessment to reduce carbon emissions. However, existing methods of assessment system include inefficiency in the process of CO2 calculation requiring considerable data input. Therefore, the purpose of this study is to develop an efficient building assessment system appropriate to material production in construction stage. To that end, quantity input technology was limited to data mapping. Also quantity calculation based on work breakdown structure and item codes consisted of hierarchical structure that is based on facet classification were analyzed. As a result, connectivity links of quantity calculation and CO2 functional units through item codes for data mapping, and assessment system including calculation and database parts were developed.

  • Recently, various conformal geometric methods have been presented for non-rigid surface matching and registration. This work proposes to improve the robustness of conformal geometric methods to the boundaries by incorporating the symmetric information of the input surface. We presented two symmetric conformal mapping methods, which are based on solving Riemann-Cauchy equation and curvature flow respectively. Experimental results on geometric data acquired from real life demonstrate that the symmetric conformal mapping is insensitive to the boundary occlusions. The method outperforms all the others in terms of robustness. The method has the potential to be generalized to high genus surfaces using hyperbolic curvature flow.

  • This paper describes preliminary results we have obtained in developing a computer vision system based on active IR illumination for real time gaze tracking for interactive graphic display. Unlike most of the existing gaze tracking techniques, which often require assuming a static head to work well and require a cumbersome calibration process fur each person, our gaze tracker can perform robust and accurate gaze estimation without calibration and under rather significant head movement. This is made possible by a new gaze calibration procedure that identifies the mapping from pupil parameters to screen coordinates using the Generalized Regression Neural Networks (GRNN). With GRNN, the mapping does not have to be an analytical function and head movement is explicitly accounted for by the gaze mapping function. Furthermore, the mapping function can generalize to other individuals not used in the training. The effectiveness of our gaze tracker is demonstrated by preliminary experiments that involve gaze-contingent interactive graphic display.

  • The range of art has been gradually expanded with the passage of time. Science and technology have also contributed to the arts in the name of media art, and artists and technicians have become collaborative. In this paper, we investigate the meaning of collaboration in art and analyze the case focusing on Projection Mapping which is a field of Media Art. In particular, this study propose the concept and production process of Sequential Collaborative Projection Mapping works, and see the work of making and exhibition as one experiment. Based on this, sequential collaborative procedures are defined in the case of work production, and the underlying technologies and procedures for collaboration are presented. The presented techniques and procedures can be applied to projection mapping exhibitions and festivals as a platform. In this process, we have reviewed the collaborative relationship between artists and technicians, and the issues with regard to giving and receiving the credit of works.

  • In this work, we define the concept of a mixed G-monotone mapping on a modular metric space endowed with a graph, and prove some fixed point theorems for this new class of mappings. Results of this paper extend coupled fixed point theorems from partially ordered metric spaces into the modular metric spaces endowed with a graph. An example is presented to illustrate the new result.

  • People have expected a humanoid robot to move as naturally as a human being does. The natural movements of humanoid robot may provide people with safer physical services and communicate with persons through motions more correctly. This work presented a methodology to generate the natural motions for a humanoid robot, which are converted from human motion capture data. The methodology produces not only kinematically mapped motions but dynamically mapped ones. The kinematical mapping reflects the human-likeness in the converted motions, while the dynamical mapping could ensure the movement stability of whole body motions of a humanoid robot. The methodology consists of three processes: (a) Human modeling, (b) Kinematic mapping and (c) Dynamic mapping. The human modeling based on optimization gives the ZMP (Zero Moment Point) and COM (Center of Mass) time trajectories of an actor. Those trajectories are modified for a humanoid robot through the kinematic mapping. In addition to modifying the ZMP and COM trajectories, the lower body (pelvis and legs) motion of the actor is then scaled kinematically and converted to the motion available to the humanoid robot considering dynamical aspects. The KIST humanoid robot, Mahru, imitated a dancing motion to evaluate the methodology, showing the good agreement in the motion.

  • As various methodologies for business process analysis and design have been conducted in many organizations by their own ways, those methodologies are not compatible each other. In order to reduce the cost of analysis for organizations. some mapping methods between different methodologies need to be developed. UMM(UN/CEFACT Modeling Methodology) that has an object-oriented point of view. can overcome the limits of existing bottom-up approaches and make it reasonable. It also simplifies the business and administrative procedures. IDEF( Integrated Definition Language) with a structural point of view that has been widely used as a system analysis and design method, needs to be mapped to UMM in order to reuse the existing IDEF models. In this study, we propose a guideline that deals with procedures of utilizing IDEF models from which we want to derive the UMM models for developing an electronic commerce system including electronic documents exchange. By comparing IDEF and UMM, we analyze the differences between those two methodologies. Based on these differences. we suggest the basic strategies for mapping method from IDEF to UMM. We also propose a mapping guideline that can make UMM results from the modeling results of IDEF. We can take an advantage of the existing IDEF analysis design results when we adopt UMM methodology for electronic business system. Many analysts who are familiar with the IDEF methodology can develop UMM work-flow by utilizing their existing results and skills.

  • The purpose of this study is to verify the applicability of concept mapping in the process of planning of network outcomes in social welfare. Planning and evaluation of network outcomes involve many stakeholders. Recognizing the value and range of individuals' perspectives in the creation of a common framework is one of the biggest methodological challenges for planning of network outcomes. Concept mapping is a kind of methodology that creates a stakeholder-authored visual geography of ideas from a group. It uses both a quantitative and qualitative approach, including brainstorming, structuring the statement, specific analysis and data interpretation methods to produce maps that can then be used to guide planning and evaluation efforts on the issues that matter to the group. 13 network managers who work in the social welfare centers in Busan are core participants. The 50 statements on network outcomes from brainstorming session fell into six distinct clusters. After the interpretation session these clusters were rated according to the seven rating scales. This paper explores applicability of concept mapping in the process of planning of network outcomes in social welfare. Concept mapping helps stakeholders with different value and ideas about network outcomes to consensus on common conceptual framework. In addition, a multidimensional conceptualization of network outcomes was made. It will assist in designing future outcomes evaluation and guide the evaluators through a selection of key activities and outcomes.

  • In this paper, we propose a method for constructing RDF knowledge graphs from objects in OOP. RML mapping has been the de-facto way of generating RDF graphs from heterogeneous data. However, the input to an RML mapping is limited to the data in files or databases. Our new RML implementation, designed to overcome the limit, has two differences compared to existing RML implementations. First, our implementation provides a new way to specify mapping rules in the form of special comments known as annotations in the source code. It is because existing works do not provide a means to refer to specific program elements to which the mapping rules will be applied. Second, our work provides mapping engine as a library, whereas the engines in existing studies runs in an independent process. Therefore, our mapping engine can be easily embedded in other applications to access in-memory objects to be mapped. In this system paper, we describe the proposed system in detail and present the results of RML test cases execution to confirm the usefulness of the system.
