  • Amongst various methods of interpreting art, a understanding of the intention of artistic creation has been traditionally considered the most essential. Hermeneutics is the typical way of approaching it. With a focus on interpretation and understanding of the object, Hermeneutics delves into methodological techniques of interpretation and understanding of the existence of art from ancient Greece to the present. Nevertheless, from the Hermeneutic viewpoint, art as the object of interpretation is not free from social conditions and tradition; for this reason, interpretation of art basically has a socio-historical aspect. The starting point of this thesis is to examine the methods of understanding art from the socio-historical viewpoint. For this purpose, I study the theory of Hermeneutics as a basic of socio-historical interpretation of art, calling for methodology I need to justify inter-dependency of the epistemological viewpoint aid the ontological viewpoint in interpretation of art. Here, I suggest 'imputation(Zurechung)' and 'cycle(Zirkel)' as methodological concepts to support interdependency of these two viewpoints in Hermeneutics. Zurechung means explanation of meaning based upon the higher standard that includes to object of interpretation, while Zirkel means perception of part in order to understand the whole and, in turn, recognition of the whole in order to understand the part. These two concepts function inter-dependently in clarifying the object of interpretation and various problems of understanding human beings derived from it in the process of interpretation. This is also a key to the explanation that the object in social condition is closely related to historical perspective.

  • When caught in a fire inside a building or a tunnel the generated smoke is the main cause of the bad visibility, which makes it difficult for a person to find escape route. Therefore of the fire simulation it is required to visualize the simulated results of smoke realistically form a viewpoint of a person caught in a fire. In the present study, developed is a CFD post-processor which can visualize the object through smoke from the results of CFD fire simulation. Examples of some applications of the program are shown in the paper.

  • The equipment of industrial robot in manufacturing and assembly lines has rapidly increased. In order to achieve high productivity and flexibility, it becomes very important to develop the visual feedback control system with Off-Line Programming System(OLPS). We can save much efforts and time in adjusting robots to newly defined workcells by using OLPS. A proposed visual calibration scheme is based on position-based visual feedback. The calibration program firstly generates predicted images of objects in an assumed end-effector position. The process to generate predicted images consists of projection to screen-coordinates, visible range test and construction of simple silhouette figures. Then camera images acquired are compared with predicted ones for updating position and orientation data. Computation of error is very simple because the scheme is based on perspective projection which can be also expanded to experimental results. Computation time can be extremely reduced because the proposed method does not require the precise calculation of tree-dimensional object data and image Jacobian.

  • A visual servoing algorithm is proposed for a robot with a camera in hand. Specifically, novel image features are suggested by employing a viewing model of perspective projection to estimate relative pitching and yawing angles between the object and the camera. To compensate dynamic characteristics of the robot, desired feature trajectories for the learning of visually guided line-of-sight robot motion are obtained by measuring features by the camera in hand not in the entire workspace, but on a single linear path along which the robot moves under the control of a, commercially provided function of linear motion. And then, control actions of the camera are approximately found by fuzzy-neural networks to follow such desired feature trajectories. To show the validity of proposed algorithm, some experimental results are illustrated, where a four axis SCARA robot with a B/W CCD camera is used.

  • One distinguishing feature of BIM(Building Information Modeling) is the objectification of spatial elements independently, which makes it easy to represent spatial network. From this perspective, this study aimed to develop the spatial network analysis tool based on open BIM technologies. From the literature review, an object model of spatial network with nodes and links and a process model from construction to visualization were established. A prototype system implementing the proposed models, named SNAT(Spatial Network Analysis Tool), was developed in Java platform with using its open source packages. SNAT can create a spatial network from IFC-BIM model, calculate the indices of spatial network analysis, and visualize it with the representing types(map, graph, matrix and table).

  • Honorific agreement is one of the main properties in languages like Korean, playing a pivotal role in appropriate communication. This makes the deep processing of honorific information crucial in various computational applications such as spoken language translation and generation. This paper shows that departing from previous literature, an adequate analysis of Korean honorification needs to involve a system that has access not only to morpho-syntax but to semantics and pragmatics as well. Along these lines, this paper offers a constraint-based HPSG analysis of Korean honorification in which the enriched lexical information tightly interacts with syntactic, semantic, and pragmatic levels for the proper honorific system.

  • The major purpose of this study is to show the insufficiency of traditional epistemology and consructivism as epistemology of mathematics education. Traditional epistemology such as empiricism, rationalism, Kant's epistemology, and Piaget's genetic epistemology is not sufficient to explain episteme in educational situation because it regards that epsteme is the phenomenon occurs between the abstract individual subject and the object world. Modern epistemology like constructivism recognize the public or social character of epsteme. So it is more appreciate than traditional epistemology to explain episteme in math educational situation. But constructivist pedagogy derived from constructivist learning theory has the following important shortcoming: The lack of clear criteria by which instructional effectiveness might be evaluated from a constructivist perspective.

  • This paper develops an algorithm for efficiently computing the intersection points between rays and an object in a simulated radiograph. This algorithm allows interactive calculation of simulated radiographs for very complex parts. It needs a geometric model of a part which is approximated by a bounding surface made up of flat triangular polygons. Since rays have a point source, a perspective transformation is applied to convert the point source problem to one that has parallel rays. This permits to use a scan-line algorithm which utilizes the coherence of the grid of rays for the intersection calculations. The efficiency of the algorithm is shown by comparing compute time of the intersection calculations to a commercial software that computes each ray intersection independently.
