Defects of corrugated board were limiting factors to the corrugated industry's growth. On-line detecting systems of defects are beneficial to increase profits of the corrugated board companies by reducing base paper consumption, increasing process reliability, and increasing productivity. By replacing naked eye inspection of defects to a defects detecting system, continuous inspection without fatigue may guarantee final products quality. The system was developed, which was consisted of line scan CCD camera, lens, illuminating parts, high speed image processor, software, various input parts, and output parts. First installation location of the system was at before fluting process after base paper unwinding, and surface of liner board was inspected by the system. Second installation location was after fluting process and combining process for liner board. Production loss includes ragged appearance of edge, irregular flute shape, wrong combination of flute, score cracking, defects in base paper, and flute cracking. The production loss was analyzed before and after the system installation at a commercial domestic mill. The production loss ratio was defined as a production loss weight per total production weight. The production loss ratio before the installation was decreased a lot from 1.28%(during 3 months before installation) to 0.76%(during 12 months after the first installation) and to 0.25%(during 6 months after the second installation).

The perspective representation and its effect that appeared in the tombs and mural paintings of koguryo are summarized as follows: First, The inside structure of the tombs is likely to show the deepness effect, placing each function in the front and both sides centering around the mane pillars and creating the boundaries and the spaces that have various visibility between the inside and outside spaces of the structure just like a traditional Korean house shows. In addition, The deepness effect is emphasized by suggesting that the spaces are countinued with a storage attached behind the main house or by forming the level and deployment in a narrow space like the scene that a large array is looked out from the main house. Second, The deepness effect is expressed by making the form of ceiling turn to a vertical space of an ascending image, constructing it just as the lotus lamp ceiling of a wooden architecture or drawing it just like the imaginary heavenly world with the sun the moon and mythical fairies and animals spread in it. Thried, The perspective effect is disclosed by drawing the mural pictures in an equally set bird's-eye view without regard to the disfance proportion according to the conceptual visualization which is not a visual penetration, adopting the multiple view points and moving view points that are moving around as an important manner of seeing. Fourth, The deepness effect is emphasized through the scene of changing spaces when they are looked out far or looked into depending on a viewpoint of the daily life by forming the fromes of paintings that we made up with actual pillars, Du Gong, crossbeams or that are painted in most tombs. Fifth, The rich spatial senses are reflected by originating the characters of the three directions, level, deployment and ascending. An example which can support the conclusion of this study can be given here. that is, the construction ground plan of a dwelling house of a nobleman at the end of Koguryo as a remain which was excavated at Dongdae Ja in Jip An.

This paper examined the contemporary kasaya of each country in Asia, focussing on the Kasaya Kongyang ceremony and kasaya varieties. As well, the countries in Asia were divided into the southern Buddhist countries, northern Buddhist countries, and Tibetan buddhist countries, and were comparatively analyzed. 1. In terms of the Kasaya Kongyang ceremony, now days the southern Buddhist countries perform the Katina ceremony, passed down from the time of the Buddha. In the northern Buddhist countries, namely China, the kasaya is bestowed to the monk at the end of the precepts ceremony, while in Korea, the kasaya is bestowed to the monk at the end of the ceremony of "opening the eye" of an image. There is no Kasaya Kongyang ceremony in Japan and Tibetan Buddhist countries. 2. In terms of the varieties of kasaya, because the Katina ceremony is performed with 5 jo in southern Buddhist countries, their kasayas are made up of 5 jo, with the exception of Myanmar's sungari. In Taiwan and Korea, which are of the Zen order and part of the northern Buddhist countries, there are 5-25 jo. In Japan, which is of the Kyo, or doctrinal order, it is made up of 5-9 jo. The Tibetan Buddhist countries have only jo that are 7 and 23. In conclusion, when Buddhism was transmitted from the southern Buddhist countries to the northern Buddhist countries, we can see that the Kasaya Kongyang ceremony and the from of the kasaya itself changed from practical robes to majestic ones, in accord with the Mahayana doctrine of saving all sentient being. Therefore, the kasaya simbolizes the Buddhist philosophy that Mahayana claims the existence of many Buddhas at one and the same time.same time.

Recently, polymer insulators that are used for high voltage applications have some advantages such as light weight, small size, vandalism resistance, hydrophobicity and easy making process. During outdoor service of polymer insulators, the surface of the insulating material is frequently subjected to moisture and contamination that lead to dry band arcing. Their tracking resistance, erosion resistance, end sealing and shed design are very important because dry band arcing causes degradation of polymer surface. Aging test to estimate life property of polymer insulator is executed through several international standard such as IEC 61109 and CEA tracking wheel test, but is not getting clear conclusion yet. There are two methods in the diagnosis method of polymer insulator such as off-line and on-line. The diagnosis methods in off-line are external condition analysis by the eye, contaminant analysis on surface, surface analysis, pollution withstand voltage test, power frequency flashover voltage test, lightning impulse flashover test, tensile fracture load test and flexural load test. Polymer material is also investigated it's tracking resistance by adding surface active agent in IEC 587. In this paper, the tracking performance of polymer insulator with salt solution which is added surface active agent. The diagnosis of insulator sample has been analyzed by leakage current and visual examination, STRI guide and thermal image camera.

Communication occurs through verbal elements, which usually involve language, as well as non-verbal elements such as facial expressions, eye contact, and gestures. In particular, among these non-verbal elements, gestures are symbolic representations of physical, vocal, and emotional behaviors. This means that gestures can be signals toward a target or expressions of internal psychological processes, rather than simply movements of the body or hands. Moreover, gestures with such properties have been the focus of much research for a new interface in the NUI/NUX field. In this paper, we propose a method for recognizing the number of fingers and detecting the hand region based on the depth information and geometric features of the hand for application to an NUI/NUX. The hand region is detected by using depth information provided by the Kinect system, and the number of fingers is identified by comparing the distance between the contour and the center of the hand region. The contour is detected using the Suzuki85 algorithm, and the number of fingers is calculated by detecting the finger tips in a location at the maximum distance to compare the distances between three consecutive dots in the contour and the center point of the hand. The average recognition rate for the number of fingers is 98.6%, and the execution time is 0.065 ms for the algorithm used in the proposed method. Although this method is fast and its complexity is low, it shows a higher recognition rate and faster recognition speed than other methods. As an application example of the proposed method, this paper explains a Secret Door that recognizes a password by recognizing the number of fingers held up by a user.

The study has sought to explore how fashion emerges as a comprehensive tool of dress for increasing its brand appeal and express one's artistic sense and fashion by using everything from make-up to hair to trappings. Therefore, when it comes to fashion trends reflected in collections, the study is designed to improve understanding of make-up as one of the elements of total fashion and to help create diverse ideas in expressing creative and free make-up that can help perfect fashion concept in harmony with all the other elements. The study has pondered upon collection, trends and fashion make-up through literature study, and has gathered image data via the Internet. It also has conducted analysis of Ethnic style reconstructed combining past and the future, East and the West, and futurism style using asymmetrical forms without no defined patterns and hi-tech textures, which emerges as a result of post-modernism. The results of the study are as follows. Ethnic fashion that pursues strange and exotic beauty is characterized by its simple and idyllic images of traditional costume in Asia or primitive clothes in Africa. Make-up represent images of matt and pale skin, tanned yellow, glossy and thickly powered squeaky white skin. Point make-up highlighted eye lines, red chick, small and voluptuous red lips. Hair and accessory seeks diversity combining various ethnic styles together such as oriental, Indian, Islam and Africa. In addition, future-oriented fashion of the 21st century, twists in texture, various kinds of materials and changes in technique help give impressions of freedom and bizarreness.
