The object-oriented(OO) distributed real- time(RT) programming movement started in 1990’s and is growing rapidly at this turn of the century Distributed real-time simulation is a field in its infancy but it is bounded to receive steadily growing recognition for its importance and wide applicability. The scheme is called the distributed time-triggered simulation scheme which is conceptually simple and easy to use but widely applicable. A new generation object oriented(00) RT programming scheme is called the time-triggered message triggered object(TMO) programming scheme and it is used to make specific illustrations of the issues. The TMO structuring scheme is a general-style components structuring scheme and supports design of all types of component including hard real time 1 objects and non real time objects within one general structure.

This study aims to examine the brief statement about the historiography of architecture by the French philosopher Michel Foucault and the possibility of a historical description according to his method. His historiographic proposition, "the history of architecture back in (the) general history of techne," is a novel idea not only for his contemporaries but also for us. To grasp the meaning of Foucault's proposition, we begin by considering his position with regard to architecture or architectural space in certain discussions till then. We then compare his standpoint on historical recognition with other viewpoints about historical narratives that can be found in books written since 1930. Finally, we interpret the concept of "techne" in the sense of "relation," whose objectivation is for him his concern on architecture and examine possible aspects and their limits.

This study is meaningful in that it builds the basic data necessary for developing skinny jeans for Korean women in their 20s based on the level of satisfaction with the apparel fit by body parts and brand choices gathered from studies on the skinny jeans consumption pattern among students in their 20s and on the results of the movement functionality and appearance sensory tests conducted on skinny jeans from six labels with the highest market share, popularity, and brand recognition, with the goal of developing skinny jeans for Korean women in their 20s.

This paper presents a threat list acquisition method in an engagement area using the support vector machines (SVM). The proposed method consists of track creation, track estimation, track feature extraction, and threat list classification. To classify the threat track robustly, dynamic track estimation and pattern recognition algorithms are used. Dynamic tracks are estimated accurately by approximating a track movement using position, velocity and time. After track estimation, track features are extracted from the track information, and used to classify threat list. Experimental results showed that the threat list acquisition method in the engagement area achieved about 95 % accuracy rate for whole test tracks when using the SVM classifier. In case of improving the real-time process through further studies, it can be expected to apply the fire control systems.

The process of detecting edge in an image is an important component of many Pattern Recognition and Computer Vision applications. In many practical cases, there exist blurred images due to defocussing, movement of an object and so on. In addition, local perturbation noise can be added to the images. We propose the edge detection technique in blurred and noisy image. For this, we use Fuzzy pyramid linking mothod to remove noise and enhance the edge in images. We develop contrast intensifier using the concept of Fuzzy sets as a postprocessing.

사람과 기계의 의사소통을 위해 기본적으로 개발된 방식은 사람의 문자를 기계어로 바꿔주어 작성된 이진 코드들을 기계가 인식하는 방법이었다.[1] 이는 중간 처리기만 이용하여 쉽게 언어를 변환하는게 가능하였고, 현재까지도 가장 많이 이용되는 방법이다. 하지만 문자를 이용하는 방식 또한 평상시 사람들이 사용하는 언어가 아닌 기계어로의 변환이 용이하도록 미리 정의된 단어들을 사용하기 때문에, 일반적인 사람들이 이용하는 데에는 어려움이 있다. 본 논문에서는 사람의 손동작 영상을 이용한 컴퓨터 제어시스템을 제안하고자 한다.

With the mark of the fourth industrial revolution, the smart factory is evolving into a new future manufacturing plant. As a human-machine-interactive tool, augmented reality (AR) helps workers acquire the proficiency needed in smart factories. The valuable data displayed on the AR device must be delivered intuitively to users. Current AR applications used in smart factories lack user movement calibration, and visual fiducial markers for position correction are detected only nearby. This paper demonstrates a marker-based object detection using perspective projection to adjust augmented content while maintaining the user's original perspective with displacement. A new angle, location, and scaling values for the AR content can be calculated by comparing equivalent marker positions in two images. Two experiments were conducted to verify the implementation of the algorithm and its practicality in the smart factory. The markers were well-detected in both experiments, and the applicability in smart factories was verified by presenting appropriate displacement values for AR contents according to various movements.

In order to minimize casualties in case of a fire in a building, it is necessary to anticipate the time required for evacuation of occupants and the delay in evacuation in advance, and prepare countermeasures for possible occurrences. In fact, various factors that cannot be predicted exist and cannot be considered by excluding them, so the risk is predicted and evaluated through quantitative evacuation modeling. In order to understand this, we analyzed domestic and international evacuation modeling research trends. For about 40 years, starting with the characteristics of human movement, an evacuation modeling technique based on scientific methods has been developed through actual fire accident cases and various real-world experiments with humans. Then, in order to analyze the natural reaction of humans, which has a decisive influence in the recognition and decision-making phase, evacuation modelling studies have been conducted in depth using psychological and physical experimental methods.
