This study compared the work environment colors and the colors of working clothes by conducting a field survey of domestic machinery manufacturers who are playing a central role in Korean industries so as to develop and evaluate working clothes based on the safety of workers and environmental harmony. For the study method, after the color-related requirements were collected through interviews and field surveys, the fabrics for working clothes were woven and the colors were selected using the requirements. The designs of working clothes were developed with an emphasis on color design. The colors of the working clothes were also analyzed in their relationship to the working environment. The evaluations were separately performed for the appearance and the colors with workers of D machinery manufacturing company. The appearance and color satisfaction, safety, psychology, and harmony with environment were evaluated on a 5-point scale by workers and their safety managers. Furthermore, pictures of the workers in their existing working clothes and the newly developed working clothes were taken with a digital camera while they were working in the field. The RGB values of the pictures were extracted using Photoshop ver. 7.01, which were converted to HVC values using Munsell Conversion ver. 4.0.1. This study found that higher satisfaction levels were shown for the newly developed working clothes compared to the existing ones. The actual measurements also showed that the newly developed had higher brightness and clearer chromatic contrast than the existing ones, indicating higher explicitness and attention for safety of workers. These types of studies can contribute to the integrated working environment plan of machinery manufacturers.

In this paper we propose a haptic interaction system that physically represents the underlying geometry of objects displayed in a 2D picture, i.e., a digital image. To obtain the object's geometry displayed in the picture, we estimate the physical transformation between the object plane and the image plane based on homographic information. We then calculate the rotated surface normal vector of the object's face and place it on the corresponding part in the 2D image. The purpose of this setup is to create a force that can be rendered along with the image without distorting the visual information. We evaluated the proposed haptic rendering system using a set of pictures of objects with different orientations. The experimental results show that the participants reliably identified the geometric configuration by touching the object in the picture. We conclude this paper with a set of applications.

Nowadays, many satellites regularly produce digital multispectral images of the earth's surface. Multispectral images may be displayed as color pictures by selecting three components for assignment to the primary colors. It is desired to enhance these images to generate a display picture that are representativde of their features. in this paper, a false color image processing algorithm is proposed for the purpose of enchancement of the multispectral images based on the human perception. The mean of each primary component is transformed to equalo. Intensity and saturation are enhanced by modified piecewise linear contrast strectching and saturation enhancement method. The proposed method has been successfully applied the LANDSAT TM image and shows good enhancement.

This study presents methodology and tools for remote measurement of the orientation of the rock parting surfaces. Two close circuit video camera capture the pictures of a rock excavation surface while a laser beam scans the surface. Positions of the laser beams in the two digital images are recognized by image processing. Using the stereoscopic concept, three dimensional coordinations of the rock surface and the orientation of the rock parting planes are calculated. Point, cross and line type laser beams are tested for better image processing results and measurement accuracy of the coordinates. According to a simple accuracy test, cross beam show better results than the point beam. However, line beam show more promising results for the measurement of the rock parting surfaces.

In this paper, we introduce a system that detects all kinds of violations at a street intersection such as red light running, speed violation, stop line violation and lane violation by tracking individual vehicles. Two cameras are used for defecting violations. One is an analog camera for real-time tracking and the other is a digital camera for license plate reading. This system is connected to the traffic signal system controller and monitors the red, arrow, yellow and green phases of an approach. Two loops in the road are used to detect vehicle approach and speed. The system takes pictures of all vehicles passing a second loop and tracks the vehicles until they go out a street intersection...

The DMB recently standardized in Korea is a Eureka-147 DAB(Digital Audio Broadcasting)-based standard which is able to provide multimedia services including moving pictures, still images, text and etc. That has the structure to add the MPEG media codec and the MPEG system, namely, video-multiplexer to the DAB system. In this paper, we analysis the video-multiplexer of the DMB standard and propose a new multiplexer, namely. M4GM(MPEG-4 General Mux) included in the DMB vido-multiplexer for the performance improvement with respect to the transmission efficiency and the expansible functions. In addition, we simulate the two video-multiplexers and then compare and estimate their performance entirely.

This paper presents the results of laboratory experimentals to remove $SO_2$ and $NO_x$ by a pulsed corona discharge in the wire-plate reactor. A rotating spark gap switch was used to generate the pulse by chewing the dc high voltage. Repetition frequency of the pulse was 60Hz and rising time of 50ns. The photo pictures of positive streamer corona taken by ICCD camera, pulse voltage and current were measured using a digital oscilloscope. Simultaneous effects of $C_{2}H_{4}$ injection and heterogeneous chemical reactions on nonthermal plasma process to remove $SO_2$ and $NO_x$ from flue gas were investigated in the present study

This paper interprets the work of Hans Bellmer, who took pictures after making a doll and distorting its form, and Diane Arbus, who took documentary photographs of unusual and marginalized people, as uncanny anxiety referred to by Freud. Through these two photographers' works, this paper examined how anxiety was used as an aesthetic strategy, and discussed the uncanny as an aesthetic experience. Uncanny refers to the phenomenon of familiar things being repressed and returning to their original place, or the phenomenon of familiarity being alienated due to repression. The aesthetic strategy of uncanny is used to bring a blind spot in reality that can be easily missed with an ordinary vision into the fore, by allowing for the slight shock to an appreciator. The ultimate goal of uncanny aesthetics is to promote both inner and external changes as well as to expand the scope of imagination, through freely crossing the borders between consciousness and unconsciousness, sympathy and antipathy, and reality and fiction.

With the aging of buildings, the number and importance of regular inspections of buildings are increasing. The current safety inspection goes through a procedure in which a skilled technician visits an old building, visually checks it, takes a photo, and finally organizes and judges it at the office. For this, field personnel and analysis and review personnel are required. Since the inspection procedure includes taking pictures, a huge amount of data has been accumulated from the time digital photos were used to the present. When a model that can check cracks outside a building is developed using these data, manpower and time required can be greatly reduced. Therefore, this study aims to create a model for classifying cracks that occur outside the building through the artificial intelligence method. The created model can be used as a basic model for determining cracks only by external photography in the future, and furthermore, it can be used as basic data for calculating the size and width of cracks.
