To find the best intagliated shape on edgelit signboard, it was prepared wilt variations of illumination by changing the depth and angle of an engraved letter, the thickness of acrylic panel and wavelength of light source in this paper. As the result of analyzing optical design program, shallower depth and larger than critical angle on a visible side of panel, a favorable illumination characteristics was found. Also considering those factors, it was able to select the model which showed effectively engraved letter.

A robust and efficient text extraction is very important for an accuracy of Optical Character Recognition (OCR) systems. Natural scene images with degradations such as uneven illumination, perspective distortion, complex background and multi color text give many challenges to computer vision task, especially in text extraction. In this paper, we propose a method for extraction of the text in signboard images based on a combination of mean shift algorithm and weighting scheme of hue and saturation in HSI color space for clustering algorithm. The number of clusters is determined automatically by mean shift-based density estimation, in which local clusters are estimated by repeatedly searching for higher density points in feature vector space. Weighting scheme of hue and saturation is used for formulation a new distance measure in cylindrical coordinate for text extraction. The obtained experimental results through various natural scene images are presented to demonstrate the effectiveness of our approach.

This study examines the characteristics of landscape elements and the reappearance techniques of traditional landscape image in Chinatown of the Shanghai Street in Busan, Korea. The subjects of the study are commercial buildings owned by Chinese residents, commercial buildings' naming design and environmental sculptures in the Shanghai Street. The results are as follows: First, the design methods of the front side of commercial buildings were classified into two parts: facede design of buildings and signboard design. The design form of the buildings' facades were classified into five types, there are: emphasis type on Chinese characters' signboard, addition type on decorative signboard, introduction type of traditional patterns, imitation type of traditional architectures and modern architectures' modes. The signs of chinese commercial buildings were observed mostly as having a traditional Chinese font in yellow/white on a red background. It has been found that this style was the most popular method of sign design. Secondly, The commercial buildings' naming design was analyzed into design methods and meanings. Design methods were classified into three types: a combination of meaning and place, a combination of season and atmosphere and tourist attractions. The meaning of the commercial buildings' names was divided into three kinds: the wishes of the prosperity, elegant type and the appropriation of local attractions. Thirdly, the environmental sculptures of Shanghai Street were found to have been influenced by both through out Chinese culture with mixed Korean culture. Finally, as for characteristics of landscape elements, we found three reappearance techniques - addition, replacement, juxtaposition. The technique of addition is added new face to the base map by just two methods - extending and overlapping area. Replacement is created new faces from base map by the action of replacing, it has three types - local replacement, package replacement, successive replacement. Juxtaposition is the fact of two or more things placed together with contrasting effect, it also has three types - the same kind juxtaposition, a different kind juxtaposition, topological juxtaposition. This study is the basic research which is analyzing the landscape design in chinatown. But the research only on Shanghai Street may have some limits in scope. It is considered an necessary study to add, which is about chinatown in other city such as Incheon, Jeonju. Then it is expected that the results of this study can be used for the basic data of the landscape plans, that municipalities are actively progressing their respective development projects of Chinatown.

Service design refers to an activity to design a user's service experience and a design area for professionally executing it. In order to design services from the people's point of view away from the supplier-oriented policy decisions in the past, the recent public participation business model using the service design methodology is increasing. In particular, the Ministry of Public Administration and Security formed the 'National Design Team' in 2014 to design services from the perspective of the public throughout the policy process. The public participatory policy model is being operated in which the public as policy consumers, service designers and public officials as suppliers participate in the overall policy process to develop and develop public services through service design techniques. This study is meaningful in that it presented the developmental direction of the actual project site through the case of the National Design Team sign improvement project with the goal of establishing a regional revitalization strategy using the service design methodology. However, as this study is about the current project, verification of the application of future project sites and user satisfaction evaluation have not been conducted. When the project is completed in the future, it is necessary to conduct a project satisfaction survey targeting consumers.

An embedded monitoring and control system which can be controlled and monitored with web, was implemented in this paper. The principal data which should be controlled are the present temperature and pH of a fish farm. The input signals are from temperature sensors and pH sensors. The input data are digital which are A/D converted every constant time, and the results are stored to the database. The converted data are displayed on a large electric signboard at the fish-farm. This system was designed that supervisors can control the system and watch the real situation of the fish-farm at remote places.

This paper is to be pre-processing that decides the text recognizability and quality contained in natural image. Differentiated with the existing studies, In this paper, it suggests the application of partially unified color models, Coiflet Wavelet and text extraction algorithm that uses the closed curve edge features of LoG (laplacian of gaussian)operator. The text image included in natural image such as signboard has the same hue, saturation and value, and there is a certain thickness as for their feature. Each color element is restructured into closed area by LoG operator, the 2nd differential operator. The text area is contracted by Hough Transform, logical AND-OR operator of each color model and Minimum-Distance classifier. This paper targets natural image into which text area is added regardless of the size and resolution of the image, and it is confirmed to have more excellent performance than other algorithms with many restrictions.

This study was to analyse the meanings of the appropriation inherited in the modern costumes from the latter of the 20th century to the present. According to the dictionary, the meanings of a word. "appropriation" is to steal something, used in order to avoid saying this directly. The sorts of the appropriation represented in the works of Art was as follow : First. the reconstruction by the imitation of the works of a great master or partly induction of the works of a great master Second, the introduction by the history, modern art, the image of popular culture Third, the imitation by the works of photograph, etc The appropriation in the modern costumes could be distinguished as two facts : First, the appropriation of the image of popular culture, 1) the way by the induction of popular factors of the extremely routine, commonplace character 2) the way by the citation of critical sentence of society, complaint message of the situation of times. Second, the reinterpretation of the past works : 1) the way by the reinterpretation of a great artist′s works, or popular works. In accordance with its change of a standard of value of the beauty, the products of modern culture, called the artificial second image, that is, popular factor, ready made factor, a signboard, a trademark etc, was appropriated in modern costumes and was reinterpreted by the works of fashion designer′s empathy. We can say that the modern costumes is not only the products of creative, original action of fashion designers but also the mirror of times, having relationship with society.

For teaching Advertisement Drawings practically, knowledge of Outdoor Advertisement Practice must be ahead of drawing practices. For understanding and practicing of various materials, treatments, manufacturing process and arrangement on drawings, it is desirable understanding outdoor manufacturing process, and making use of a mock-up. Actually, technical books about outdoor advertisement are very insufficient. As a teaching media based on the actual field for advertisement drawings, snapshots of the field and actual process and a mock-up of a signboard was prepared for practical application.
