The purpose of this study is to analyze and understand the approach of critical fashion by comprehending the appropriation of art as a sociocultural phenomenon that influences contemporary fashion. This study inquired into the relevant literature to explain the theoretical background behind critical fashion, and conducted a case study using exhibition catalogues, exhibition works, articles, fashion magazines, and fashion-related websites in order to examine cases of appropriation strategies. As a subversion of meaning by using an existing transposable object image to deliver an experience unlike the actual image, subversive appropriation in critical fashion takes existing things as they are and rearranges them with the purpose of subverting social values while having its subversive style of appropriation. Referring to a style that focuses on labelling the distance between the subject, that refers and that which is referred to, referential appropriation has been reprogramming existing things with an internal and introspective attitudes. In other words, from an exploitative style of appropriation aimed at expanding the meaning with found in objects by avant-garde fashion designers, to a subversive style of appropriation aimed at subverting meanings with transposable objects by conceptual fashion designers, there has been a change toward the referential style of appropriation aimed at expanding artistic forms with created objects critical fashion designers.

The positions, attitudes, and internal orientation parameters of three line scanners are critical factors in order to acquire the accurate location of objects on the ground. Based on the assumption that positions and attitudes of the sensors are derived either from direct geo-referencing which of using Global Positioning Systems (GPS) and Inertial Navigation Systems (INS), or from indirect geo-referencing which of using Ground Control Points (GCPs), this paper describes on biased effects of Internal Orientation Parameter (IOP) on the ground. The research concentrated on geometrical explanations of effects from different focal length biases on the ground. The Synthetic data was collected by reasonable flight trajectories and attitudes of three line scanners. The result of experiments demonstrated that the focal length bias in case of indirect geo-referencing does not have critical influences on the quality of reconstructed ground space. Also, the relationships between IO parameters and EO parameters were found by the correlation analysis. In fact, the focal length bias in case of the direct geo-referencing caused significant errors on coordinates of reconstructed objects. The RMSE values along the vertical direction and the amount of focal length bias turned out to be almost perfect linear relationship.

A time-domain combined field integral equation (CFIE) is presented to obtain the transient scattering response from arbitrarily shaped three-dimensional conducting bodies. This formulation is based on a linear combination of the time-domain electric field integral equation (EFIE) with the magnetic field integral equation (MFIE). The time derivative of the magnetic vector potential in EFIE is approximated using a central finite difference approximation and the scalar potential is averaged over time. The time-domain CFIE approach produces results that are accurate and stable when solving for transient scattering responses from conducting objects. The incident spectrum of the field may contain frequency components, which correspond to the internal resonance of the structure. For the numerical solution, we consider both the explicit and implicit scheme and use two different kinds of Gaussian pulses, which may contain frequencies corresponding to the internal resonance. Numerical results for the EFIE, MFIE, and CFIE are presented and compared with those obtained from the inverse discrete Fourier transform (IDFT) of the frequency-domain CFIE solution.

Chair is one of objects which are closely connected with human body and is a symbol which represents human essence and culture. Symbolism embodies the meaning of expression through transfering the immaterial structure to tangible form. Therefore chair embodies the essential internal desires of human by means of its symbolic representation. In order to understand the essential human desires included in the symbolism of chair it is necessary to consider these desires with respect to cultural and historical context. in this study four essential internal desires of human are investigated through the symbolic representation of chair that is the desires on human psychological comfort authority freedom and eroticism. The purpose of this study is to emphasize the necessity of the design approach based on the understanding of essential internal desires of human which is pursued from the object by user.

This study proposes a monitoring system by cooperating the image information and the sensor information in a sensor network system. The monitoring system proposed in this study is divided into internal spaces, such as offices and laboratories, and external spaces including other various spaces. In the internal spaces, motions in objects are detected through cameras while some peripherals like lights are controlled by analyzing some temperature, humidity, and illuminance data detected by sensor nodes. In the external spaces, it is to watch certain intruders to the internal spaces through the interested region for exceptional time by installing cameras, motion detectors, and body detectors in such interested regions. In the results of the test that was applied to a practically limited environment by implementing some interfaces for the proposed system, it was considered that it is possible to watch surroundings effectively using the image information obtained from cameras and sensor information acquisited from sensor nodes.

One of the common issues in large dataset analyses is to detect and construct homogeneous groups of objects in those datasets. This is typically done by some form of clustering technique. In this study, we present a divisive hierarchical clustering method for two monothetic characteristics of histogram data. Unlike classical data points, a histogram has internal variation of itself as well as location information. However, to find the optimal bipartition, existing divisive monothetic clustering methods for histogram data consider only location information as a monothetic characteristic and they cannot distinguish histograms with the same location but different internal variations. Thus, a divisive clustering method considering both location and internal variation of histograms is proposed in this study. The method has an advantage in interpreting clustering outcomes by providing binary questions for each split. The proposed clustering method is verified through a simulation study and applied to a large U.S. house property value dataset.

As an application software in distributed computing environment becomes large, the number of objects to be created increases drastically and the interfaces among them become very complex, The concept of group object resolves this problem to some extent by grouping a set of related objects, encapsulating them and controlling their interfaces systematically. In this paper, we propose an implementation model f the group object concept in CORBA, which is a standard middle ware for developing distributed application software on heterogeneous networks. To support group objects we extends CORBA ORB without modifying its internal structure for the compatibility with existing CORBA applications. And we devise an interface definition language by extending CORBA IDL to describe group objects in a language-independent style, which is one of the most important characteristics in CORBA. Finally, we experiment the implementation model on a CORBA ORB compliant product which supports the Java language.

In this paper, we present a knowledge-based object-oriented spatial database system called KOBOS. A knowledge-based approach is introduced to the object-oriented spatial database system for data modeling and approximate query answering. For handling the structure of spatial objects and the approximate spatial operators, we propose three levels of object-oriented data model: (1) a spatial shape model; (2) a spatial object model; (3) an internal description model. We use spatial type abstraction hierarchies(STAHs) to provide the range of the approximate spatial operators. We then propose SOQL, a spatial object-oriented query language. SOQL provides an integrated mechanism for the graphical display of spatial objects and the retrieval of spatial and aspatial objects. To support an efficient hybrid query evaluation, we use the top-down spatial query processing method.

Bronchial foreign body aspirations are uncommon in adults and usually have various underlying conditions, otherwise accidentally occurred in dental procedure, medical, surgical procedure. The most commonly aspirated objects were food materials, with peanuts leading the list. When bronchial foreign body was aspirated, no definite respiratory symptoms or foreign body is may not seen, then diagnosis is delayed. Therefore late complications was developed. The tendency to use fiberoptic bronchoscope for removal of foreign bodies in adults is increased. We report a rare case of bronchial pneumonia due to occult aspiration of a twig before 1 year with a review of the literatures.

A robotic spatial augmented reality (RSAR) system combines a robotics technology with a spatial augmented reality system (SAR) where cameras are used to recognize real objects and projectors augment information and user interface directly on the surface of the recognized objects, rather than relying on handheld display devices. Moreover, a robotic module is actively used to discover and utilize the context of users and environments. The control of a RSAR system involves several issues from different technical fields such as classical inverse kinematics of motors where projector-camera pairs are mounted, inverse projection problems to find appropriate internal/external parameters of projectors and cameras, and image warping in graphics pipeline to compensate the kinematic constraints. In this paper, we investigate various control issues related to a RSAR system and propose basic approaches to handle them, specially focused on the prototype RSAR system developed in ETRI.
