In Korea, popular stars were the leaders of the latest fashion, who had the strong power in apparel market. Costume, especially wedding dress they worm became the focus of interest to single women of marriageable age and wedding dress co. This study was performed to research wedding dress design (silhouette, veil, sleeves, materials, and details) from 1960's to June. 2004. Resources were extracted from the weddings photos, 'My Wedding' magazine, 'Vogue Korea' magazine and web sites. The materials, which could not be judged on the photos, were researched from text articles. The popular stars were TV stars, musicians, and actresses. The results of this study were as follows: The wedding dress in Korea from 1960's to June 2004 had different distinguishing characteristics. 1. In 1960's, wedding dress was characterized with A silhouette, long veil, set in sleeves, and hair decoration. 2. In 1970's, H silhouette decorating by belt, long veil, puff sleeves, and ruffles hemline were in vogue. 3. In 1980's, Victorian style designed by long and wide width, the leg of mutton sleeves or tightly fitted sleeves, short veil and pearl coronet, flower decoration became popular. 4. In 1990's, to reach the elegance or romantic image, it was used race, ribbon, frill, etc., on the base of 1980's wedding dress design. Generally the girlish styles which expressed innocent and pure and feminine were in fashion. 5. In 2000's, the keyword of both luxury and simple were intended. Silhouette was designed variously, but it became slimmer and simpler. The decoration was splendorous with race, embroidery, and beads.

This paper discusses techniques for embedding data into 3D polygonal models of geometry. Much researches of Watermarking had been gone as element technology of DRM (digital rights management). But, few research had gone to 3D polygonal model. Most research is limited at text document, 2D image, animation, music etc. RP system is suitable a few production in various goods species, and it is used much in industry to possible reason that produce prototype and find error or incongruent factor at early stage on design in product development childhood. This paper is research about method that insert watermark in STL ( stereolithography) file that have 3D shape model. Proposed algorithm inserts watermark in normal vector region and facet's interior region of 3D shape data. For this reason, 3D shape does not produce some flexure and fulfill invisibility of watermark. Experiment results that insert and extract watermark in normal netter region and facet's Interior region of 3D shape data by proposed algorithm do not influence entirely in 3D shape and show that insertion and extraction of watermark are possible.

Hindi is the most widely spoken language in India, with more than 300 million speakers. As there is no separation between the characters of texts written in Hindi as there is in English, the Optical Character Recognition (OCR) systems developed for the Hindi language carry a very poor recognition rate. In this paper we propose an OCR for printed Hindi text in Devanagari script, using Artificial Neural Network (ANN), which improves its efficiency. One of the major reasons for the poor recognition rate is error in character segmentation. The presence of touching characters in the scanned documents further complicates the segmentation process, creating a major problem when designing an effective character segmentation technique. Preprocessing, character segmentation, feature extraction, and finally, classification and recognition are the major steps which are followed by a general OCR. The preprocessing tasks considered in the paper are conversion of gray scaled images to binary images, image rectification, and segmentation of the document's textual contents into paragraphs, lines, words, and then at the level of basic symbols. The basic symbols, obtained as the fundamental unit from the segmentation process, are recognized by the neural classifier. In this work, three feature extraction techniques-: histogram of projection based on mean distance, histogram of projection based on pixel value, and vertical zero crossing, have been used to improve the rate of recognition. These feature extraction techniques are powerful enough to extract features of even distorted characters/symbols. For development of the neural classifier, a back-propagation neural network with two hidden layers is used. The classifier is trained and tested for printed Hindi texts. A performance of approximately 90% correct recognition rate is achieved.

Communication underwater is severely limited when compared to communications in air because water is essentially opaque to electromagnetic radiation except in visible range. Acoustic systems are capable of long range communication, but offer limited data rates and significant latency due to the speed of sound in water. On the other hand, optical wireless communication has been proposed as one of the best alternatives to meet the requirements of the underwater observation and subsea monitoring systems. It will help In this study, we are developing an underwater optical communication system that integrates with a depot ship floating on the water. An interface between LED lighting communication system and Bluetooth module is presented to support the underwater-to-air communications. Error free image and text transmission at 3 m of water were achieved at bit rates of 230.4 kbps. This development effort will enhance infrastructure to efficiently interconnect between underwater wireless systems and command ship networks for underwater monitoring.

There are not a few mathematical terms used as the undefined terms in school mathematics. The purpose of this study is to investigate critically the undefined mathematical terms in elementary school mathematics textbooks of Korea. As the result, the following suggestions are proposed. Firstly, It is not proper to use the terms which mathematics curriculum does not allow to use in elementary school math as the undefined terms in elementary school mathematics textbooks. Secondly, everyday-based undefined terms must be defined in elementary school mathematics textbook if their mathematical meanings are different from their everyday-based meanings. Thirdly, we need to consider the consistency when we use the undefined terms in elementary school mathematics. Fourthly, undefined terms should be define newly when the contexts in which they are used are changed or expanded. Finally, in elementary school mathematics textbooks, it is needed to define some purely mathematical undefined terms that there is no evidence which shows students grasp well their meaning.

The purpose of this study was to develop cultural food contents from local dishes related to the historical and cultural heritage in the representative areas of Gurye and Jinan. The information on 'Story' was collected from each region's representative local native journal, searches of related web-sites, analysis of old literature, and interviews of traditional households. 'Telling', the conveyance, was focused on texts of literature analysis, which were synthesized from historical conditions, regional food materials, cuisine, regional symbolism, etc. The created food contents were displayed with balanced and healthy Korean food dishes after nutritional analysis. In Gurye, the content was extracted from the story of Hwang hyun (黃玹, 1855-1910) - figura of Gurye - and his collection, "Maecheonyarok", and the storytelling native food was prepared. In Jinan, the content was extracted from the text of an anecdote from "filial son Kwang-beom Lee", a local journal. We tried to express Gurye's clean image in connection with the patriot - Hwang hyun (his nick name was Maecheon), in the late period of Chosun through the unprocessed and simple nature of the dining table. As in Jinan's storytelling materials, we tried to express a healthy menu of health food for older people based on the clean nature and documents about the real character's filial behavior. The developed healthy menu and dining table properties in this study have been established in accordance with nutrient intake standards of energy in Korea.

A photograph used in a film poster summarizes the story of the film that lasts for around two hours. The image must contain a picture that represents the story and text including the title, with various design elements composed in a harmonious way. However, given that a photograph is the most noticeable element in a film poster, this study aims to examine the function, role, and types of a film poster and analyze poster photographs. Currently, there are companies specialized in photography for film posters, but sometimes recognized photographers are commissioned to take a photograph that will be used for a film poster. Hein-kuhn Oh actively produced such photographs in the early and mid-2000s, and this study deals with 'how the photographs recreate the content of the films' focused on three selected photographs taken by him. Also, There were commonalities found between the tree photographs and Oh's personal portrait photographs, which were then analyzed from the photographic aesthetic point of view. The three selected works are: , , and .

When reviewing animation based on a mythical motive, the mythical imaginary power has been dependent only on audio visual senses thereby resorting to a fantasy nature regardless of reality, or there has been too much emphasis on an educational message and animation has been utilized as a conflicting composition between good and evil. Therefore, this thesis reviewed 1) whether the author's consciousness was reflected in animation according to the contemporary interpretation of mythical imaginary power and 2) whether the author included an internal meaning of a universal subject by having a short animation that was produced by actively utilizing a mythical motive as a text. Also, based on the analysis, the study deduced the conclusion that the most important thing in animation based on a mythical motive is the author's consciousness that reinterprets the theme of 'universality' from a contemporary perspective before expressing the mythical objects through the senses such as by a brilliant image and sound. The products of such an analysis are supposed to solve the problem over how mythical factors need to be applied and utilized in creating animation.
