This study aimed to develop and propose a Korean character group with the story of Shim Cheong applied as a motif. By borrowing the four stories (a dream of the birth of a child, filial behavior, regeneration and eyesight-gaining) presented in the story of Shim Cheong which has been passed on orally, the study designed the Korean character group and set up types of characters' roles to visualize these other characters seen in the content such as Shim Cheong the heroine, goblins, a baby dragon, Mr. Shim the blind and others. As a next step, the study applied the types to the seven essential types of Vogler's original characters. A process of how to visualize the group of those characters appearing in the story including Shim Cheong the heroine was offered. In particular, the study concentrates on figuring out how to expand and develop the Shim Cheong character to be this image of one of the most popular Korean princess characters. What this study had discussed will contribute to the field of character production when they try to commercialize characters and develop Korean characters with unique Korean features included.

This paper describes a technique for detecting the boundary of the optic disk in digital image of the retina using inward and outward curve evolution. Optic disk boundary offers medical information about glaucoma progresses. For accurate boundary detection, image inpainting based on PDE removes blood vessels crossing the optic disk. For removing noises and preserving boundary of optic disk in image inpainting process, the anisotropic diffusion filtering is developed. After pre-processing, the optic disk boundary is determined using inward and outward curve evolution. Experimental results show that blurring effect of original region and optic disk boundary is reduced considerably. By the proposed method, we can detect correct disk boundary compare to conventional method.

A true color image is needed many data on the occasion of the transmission and storage. Therefore, we want to describe color image by a minority data without unreasonableness at eyesight. In this paper, it is presented 256 colormap construction method in RGB, YIQ/YUV space and common colormap expression method at merge between colormaps by reason of dissimilar original color image to display at a monitor for each other colormap at the same time. In comparison with processed result in RGB, YIQ/YUV space, it was measured by PSNR, standard variation, and edge preservation rate using sobel operator. Process time is 3second in colormap construction and 2second in merge between colormaps. In the PSNR value, RGB space has higher 0.15, 0.34 on an average than YIQ and YUV spae. Standard variation has lower in 0.15, 0.41 on an average than Yiq and YUV space. But in the data compression, YIQ/YUV space have about 1/3 compression efficiency than RGB space by reason of use to only 4bit of 8bit in color component.

This study was conducted to develop the long-tenn storage method to minimize the black spot occurred on the surface of persimmons stored in the films at low temperature. The storage experiments were done with different films and persimmon varieties at $0^{\circ}C$ storage condition for 5 months, and then the physical and chemical characteristics of persimmons were tested monthly. The results were as follows : 1. The film 160 made from zeolites showed highest performance in well storings sweet persimmons for 5 months, compared with other films by eyesight. The initial moisture condensation inside the films seemed to cause the black spots on persimmons, and the effect of the film holes was never significant to prevent the black spots. 2. The sugar content was ranged from $14^{\circ}Brix$ to $15^{\circ}Brix$ regardless of film types and persimmom varieties, and it changed little for storage of 5 months. 3. The decrease rate of persimmom weight in the film 160 and 180 was 0.3% for storage of 5 months, while those in other films reached to 2%. The decrease rate of persimmon weight was least in the film 160 and 180. 4. The hardness of Fuyu least decreased in the films 160 and 380. It was changed from 36 kg/cnf to 8-27 $kg/cm^2$, and that of Charyang was from 31 $kg/cm^2$ to 8-10 $kg/cm^2$ for storage of 5 months. The hardness of Charyang rapidly decreased as storage period increased. 5. The average rate of black spot(defect rate) of Fuyu measured by a computer image processing system was least in the film 160 by 0.5%, but those in other films was ranged from about 5% to 20% for storage of 5 months. The rate of black spot of Charyang was less than that of Fuyu among most of films. 6. The intensity, hue, and saturation in persimmon color changed according to storage period. Especially, the intensity of persimmon colors decreased as storage period increased, but it was least in the film 160. 7. An integrated long-term storage method of sweet persimmons was suggested in the basis of the experiments and literature reviews.

This paper investigates the Buddhist sculpture and wall-painting enshrined in the halls of Bunhwangsa (Bunhwang temple) at Gyeongju in the mid-Silla period, which are thoroughly unknown to us except through textual records of Samgukyusa compiled by Priest Ilyeon in the late thirteenth century. According to Samgukyusa, a clay portrait-sculpture of Monk Wonhyo, made by his son Seolchong, was placed in Bunhwangsa. This image faced to the side, because he turned his body toward Seolchong when Seolchong bowed to this image. This story suggests that the portrait image of Wonhyo was most likely made after the Vimalakirti images, which were popular in China from the Six Dynasties period on, especially the Vimalakirti images of the early Tang period, turning his head and body toward Bodhisattva Manjusi seated opposite. The Vimalakirti image of Seokkuram might show the portrait image of Wonhyo. A wall-painting of a Thousand-Armed Avalokiresvara who has a thousand arms with a thousand eyes, called by the name 'Great Mercy with a Thousand Hands', was enshrined on the north wall of the left hall of Bunhwangsa. During King Gyeondeok's reign, Himyeong and her five-year-old blind child prayed before this image, and the blind child gained eyesight. While praying, they sang a song pleading for one of the thousand eyes which the Bodhisattva had in his hands. This song implies that Thousand-Armed Avalokiresvara had a thousand eyes, one painted on each hand. The fact that Thousand-Armed Avalokiresvara of Bunhwangsa was called 'Great Mercy with a Thousand Hands' indicates that this painting was based on the scripture Thousand-Armed Avalokiresvara Sutra translated by Bhagavaddharma in about 655, in the Tang period, which also has 'Great Mercy' in its title. In the year 755, a gilt bronze image of Medicine Buddha was made in Bunhwangsa, using nearly 61 tons of bronze to cast. The huge amount of bronze suggests it includes not only the Buddha statue but many other images such as two attendant Bodhisattvas of Suryaprabha and Candraprabha, Eight Great Bodhisattvas, or Twelve Guardians. Seven images of Medicine Buddha might have been made in accordance with the scriptural text of Seven Medicine Buddha Sutra translated by Monk Yijing. Textual evidence and recent excavation have revealed that seven images of Medicine Buddha and their whole attendant images based on Seven Medicine Buddha Sutra were made in the Nara period from 751 to 762 when Queen Gomyo contructed Sinyakusiji temple for the recovery of her husband Shomu. It is fair to assume that one or seven Medicine Buddhas and a whole group of his (their) attendant images were made for the main hall of Bunhwangsa temple in 755.
