This study suggests a direction for stage-costume design by making stage costumes based on amusement, eclecticism, and the masquerade, which are the criteria for approaching stage costume designs according to characteristics of the mask theatre presented by P. G. Bogatyryov. The conclusions of this study are as follows. First, criteria to approach stage costume design for mask theatre can be classified into amusement, eclecticism, and masquerade according to the characteristics of the mask theatre presented by P. G. Bogatyryov. Second, the stage costume of a mongrel dog showed amusement through the expression of the image of therianthropy through the combination of a fur-lined vest and wristlet, Korean traditional trousers with the paw-prints of a dog. Third, eclecticism contains diverse characteristics and escapes from being singularly defined due to the fusion of severally different heterogeneous objects. The stage costume differently used a method of wearing clothing in a different period, of choosing clothing materials, and of expressing color in every character to indicate ambiguity to which the drama points through the integration of various expression elements. Fourth, the masquerade present characters (Taembang, Daejang, and Changseok)who simultaneously play the role of fairies after having changed into a white mask and having worn Korean a traditional overcoat (Durumagi) on the original clothes; the, result is the change of the theatrical structure into another time and space inside the theatrical scene of imagination through a concealment of the original clothing.

The purpose of this study is to analyze how the aesthetic characteristics of Brecht's V-Effekt is visually expressed of the costume in the Traditional Play of Korea, China and Japan. The method and the contents of the study were to refer to the antecedent studies and the related documents to peruse the characteristics of the traditional plays of the East and West, the origin and the concept of Brecht's Verfremdung and considered the relation of Brecht's V-Effekt and the Oriental plays, and then the researcher derived the aesthetic properties of Brecht's V-Effekt. This study analyzed how those qualities of the aesthetic characteristics on the V-Effekt are manifested on the stage costumes of Korean mask, Beijing opera and Kabuki. The aesthetic qualities of Brecht's V-Effekt are classified into symbolism, grotesque disposition, character of sing and dance, comicality. The symbolism in the traditional play costumes of the three nations is shown in the colors of the masks in Korean and the tone of the colors on the costumes and the make-up in Beijing opera and Kabuki. While the properties of bizarrerie and deformation coexist in masque and Beijing opera costumes in terms of grotesque disposition, Kabuki strongly displays bizarre grotesquerie. The character of sing and dance is visually expressed through the transformation of sleeves on the three nation's traditional play costumes; Masque on the Hansam and Chengsam, Beijing opera on the Water sleeves and Kabuki on Hurisode. The comic aspection is expressed in a humorous and comical way through the distortion and transformation of forms in Masque and Beijing opera but it cannot be seen in Kabuki costume. The study as above will form the aesthetic properties of the Oriental traditional play costumes and also it will contribute to establishing the identity of Korean mask costumes.

Off-line handwritten character recognition is in difficulty of incomplete preprocessing because it has not dynamic and timing information besides has various handwriting, extreme overlap of the consonant and vowel and many error image of stroke. Consequently off-line handwritten character recognition needs to study about preprocessing of various methods such as binarization and thinning. This paper considers running time of watershed algorithm and the quality of resulting image as preprocessing For off-line handwritten Korean character recognition. So it proposes application of effective watershed algorithm for segmentation of character region and background region in gray level character image and segmentation function for binarization image and segmentation function for binarization by extracted watershed image. Besides it proposes thinning methods which effectively extracts skeleton through conditional test mask considering running time and quality. of skeleton, estimates efficiency of existing methods and this paper's methods as running time and quality. Watershed image conversion uses prewitt operator for gradient image conversion, extracts local minima considering 8-neighborhood pixel. And methods by using difference of mean value is used in region merging step, Converted watershed image by means of this methods separates effectively character region and background region applying to segmentation function. Average execution time on the previous method was 2.16 second and on this paper method was 1.72 second. We prove that this paper's method removed noise effectively with overlap stroke as compared with the previous method.

Bhutan's mask dance drama, Cham is performed in the festival of Tshechu. Originating from the 17th century, Tschechu is a religious ritual as well as a traditional festival held to commemorate the birth of Padmasambhava, who spread Buddhism in the kingdom of Bhutan. Bhutanese Cham and Tibetan Cham share similar traits in their content of , , and in their characters of Pawo and Pamo. Meanwhile, , , , , , , , are distinctive performances of Bhutanese cham. Moreover, the clown character Atsara in Bhutanese cham is a character that does not appear in the Tibetan Cham. Atsara, a humorous character, can be identified by its use of a long phallus ornament on the head or by a distorted face mask with a phallus in its hand. Bhutanese Cham, originally from Tibet, is a religious mask dance drama handed down in Lamaism temples. In later generations, new performances reflective of Bhutan's history, myth, legends, and religion were added in large amount. Thus, the Cham of Bhutan now has very independent and characteristic aspects.

Before the Korean War, Korean mask dramas had been performed as parts of seasonal customs and had been passed down in connection with various seasonal events, such as village rites, tug of war, torch fighting, Jisinbabgi(stepping on evil spirits), Gilnori, and Sattonoreum. However, after the Korean War, the dramas were played independently regardless of those seasonal events; thus, they have lost their original functions and meanings. After the Korean War, the lion dance in the Bukcheong lion mask play included two lions (as opposed to one lion prior to the Korean War) and the Aeonesung and Sadang dances were added. The scene in which a lion eats a child changed to a lion eating a rabbit doll. Furthermore, whereas mask types used to be diverse, they are now standardized to one type of lion mask. In the Yangju Byulsandae-nori, eight monks and Waejangnye, Aesadang appeared in 'Aesadang Bubgonori', but now the Malddugi mask character is added. Current performances omit sexually suggestive scenes. In the pre-Korean War version of the old man and old woman act, the old man sang a song to the soul of the dead woman, but now a shaman appears and performs an exorcism. In the dialogues, vulgar and sexual statements have been shortened as many audience members are women and children. Regarding the appearance of the masks, the lotus leaf, the monk with Scabies, and sannim masks have been significantly changed. Bongsantalchum has also changed, especially in the old monk act. Previously, two Somu used to appear whereas now only one appears. The scene of the shoe seller's and the monkey's departure is also different. Furthermore, while the former masks once had big eye holes on each side of the nose, now the masks have smaller holes on the eyes.

Masks are generated by adding different fonts of learning data characters in pixel unit, and pixel values belonging to each of the masks are divided into 3 groups. Using the directional expansion operators, we expand the text area of the test data character into 4 diagonal directions in order to create the boundary areas to distinguish it from the background area. A mask with a minimum average discordance is selected as the final recognition result by calculating the degree of discordance between the expanded test data and the masks. Image comparison using directional expansion operations more accurately recognizes test data through 4 subdivided recognition processes. It is also possible to expand the ranges of 3 groups of pixel values of masks more evenly such that new fonts can easily be added to the given learning data.

The perception of landscape structure can he formed mode clearly, with including an auditory stimulus to a visual aspect. The waterfall, as an landscape element, will be considered of not only it's function and structure in landscape architecture designing but also harmony with environment which it has been situated, and contribution to the public goad. The purpose of this study was to establish more 7rational and practical design theory for the construction of waterfall. The number of subjects investigated were 47 of waterfall located in Mt. Palgong. In this study, the acoustic character of the waterfalls were investigated as an excellent effect to mask easily sensible noises. The correlations between the structure of waterfalls and water 1a17ing sound, which were useful for waterfall design and construction, were examined. It was discovered that the position of double distance of waterfall height From the waterfall is significant in the visual and acoustic perception of waterfall.

Hahoebyeolsingut Talnori, which is under permanent performance, has lost its relevance to folklore and rituals of the villagers and has secured the possibility of change depending on the actor's choice. This article seeks to expand the current stuck performance of Hahoe mask play, which has great significance as a play and play for the audience. To this end, We studied the possibility of expanding the performance of Hahoe Talnori by trans-identity of the Choragi. Chorangi character derides yangban, seonbi and monk, who are representatives of the establishment. Those who have a consciousness of potential transformation, those who passively represent the masses, and those who are tacitly authorized by the audience to ridicule the ruling class. The audience feels exhilarated by the super-cool, but at the same time reduces the limits. We transformed Chorangi who is clever but cannot overcome the limits of his status, into a character with a sense of transformation by applying the method of turnning identity and changing identity of the theory of trans-identity. And I applied the method of expansion of the media conversion storytelling theory to create a new Chorangi Madang that conforms to the audience's needs and the spirit of the times. In addition to the performance of Yangban Seonbi Madang(Act of Nobleman and Scholar) which ends with an ambiguous reconciliation, we wanted to complete it in a way that even today's audiences could accept by applying the function of the Hahoebyeolsingut Talnori ambassador and the principle of implementation. And We writed it in a script. This article is meant to be an experimental study that attempted to transform traditional performing arts in the context of new creation of tradition. Preservation and transmission of traditional performing arts are important, but it is necessary to move forward according to the trend and spirit of the times.

Recently, with the development of ICT technology such as cloud and mobile, image utilization through social networks is increasing rapidly. These images contain personal information, and personal information leakage accidents may occur. As a result, studies are underway to recognize and mask personal information in images. However, optical character recognition, which recognizes personal information in images, varies greatly depending on brightness, contrast, and distortion, and Korean recognition is insufficient. Therefore, in this paper, we design and implement a personal information identification and masking system based on image recognition through deep learning application using CNN algorithm based on optical character recognition method. Also, the proposed system and optical character recognition compares and evaluates the recognition rate of personal information on the same image and measures the face recognition rate of the proposed system. Test results show that the recognition rate of personal information in the proposed system is 32.7% higher than that of optical character recognition and the face recognition rate is 86.6%.

Goseong Ogwangdae started academic research in the late 1950s and was designated as a national intangible cultural asset in 1964. From the time of the academic survey to the time of designation, it was recorded as using paper masks, but when the recording image was filmed in 1965, it was already changed to wooden masks. In 1960, before being designated as an intangible cultural asset, the number of masks, which was 9 points, gradually increased to 19 points in 1964. It is necessarily included in the leper, Chorani, Malttuki, Cheongbo-Yangyang, Halmi, and Jemilju, but the character of the yangban is not yet clearly differentiated. Hwangbongsa and Sangju appeared as bare faces, and consumption, milling, Cheongbo-Yangyang are used together with Bibi and inspiration. It can be guessed that Bibi was not the appearance of a foreign object with horns as it is now, considering that Bibi and Madangsoi were used together. Since 1965, shortly after the designation, the whole of the Goseong Ogwangdae mask has been changed to a wooden mask. All the characters except for resident, courtyard, and top-of-the-line are wearing masks. Bibi, Hongbaek, and service masks have never appeared until 1964. The Yangban was changed to the closing ceremony with six people in the order of Won-Yangban, Baekje, Heukje, Cheongje, Hongbaek, and Jonggadoryong. Starting in 1969, the mask enters the stable period where the kind is the same as the present. Bibi-Yangban uses both the Won-Yangban and the Jemilju uses the Somu, but all other characters use the individual mask to use a total of 18 masks. The Yangbans are clearly differentiated, and a total of seven Yangban appear. The reason why the change in the type of mask and the expression of material is so large is that the first generation of mask makers died and the tradition of mask production was cut off, but there is also a cause of the extreme change in the environment of the drama that the performers who joined after the designation had to face. Also, it is closely related to the change of the times when the meaning and weight of masking in masking has changed. At that time, the performers were not so tied to the current concept of 'original form' that they preserved the appearance of the designated time. Originally, Goseong Ogwangdae was centered on improvisation dance, not the formalized dance as it is now, and there was a certain fluid aspect in the retelling, so it was flexible in the use of masks even before the designation of cultural assets. Strict rules did not apply in the details, as it was a self-sufficient play by the performers, not an offer event. The form and contents of this fluid play are changed to preparation for the performance while preparing for the folk art contest. As the subject of the contest in self-sufficient play, dance, costumes, and props became more and more colorful as well as dancing, costumes, and props. As a result, participation in the contest brought about changes in the overall performance and changed the mask, which was accepted within the preservation society.
