Reproduction of antique document is of importance with the concept of sharing the their contents and original aspects in terms of textual and artistic message. 'Pine tree ink stick' and 'Oil ink stick' are greatly enjoyed in their uses in the most written documentary works. Thus, it is said that the approach of this study has implied considerable meanings to cultural aspects. In this work, we have performed to investigate the reproduction and restoration study for antique documents. With comparison and analysis of some types of "ink stick", we have prepared several ink samples, controlling viscosity, surfactant, thickness agent, and applied these inks to the target antique document. Several reproduced samples showed a practical application possibility in terms of reproduction and restoration.

We propose that a subjective image quality assessment based on objective image quality factors in order to evaluate objectively preference of consumers. In other words, we define objective image quality factors which are easy to accept by manufacturers and they are composed of subjective image quality assessment questionnaires. Also, portrait image is selected by stimulus in order to persue easiness of evaluation for the general subjects. Throughout a subjective image quality assessment model, we evaluate recognition of image quality by consumers and analyze the effectiveness of correlation in terms of the final image quality preference. Analyzing the relationship between image quality factors, we can figure out the preferable image quality and confirm the positive effects on consumers' recognition of image quality. In the results, there are strong relationship between preference and color reproduction, dynamic range, noise, and resolution respectively. especially, the characteristic of portrait, there is high correlation between color reproduction and preference.

The purpose of this study was to identify the structure and characteristics for the reproduction of the armor in the Unified Silla period, and then reproduce and utilize it as a cultural content. In the armor reproduction project excavated from Jaemaejeong, Gyeongju. Jaemaejeong armor is consisting of Singap (身甲, body armor), Sanggap (裳甲, hip armor), and Sangbakgap (上膊甲, upper arm armor) at the time of excavation. Unlike the armor of the Three Kingdoms period, Singap and Sanggap are separated. Singap is Yangdangsik (裲襠式, side opening method) and Gyunggap (頸甲, gorget) was not unearthed, Sangbakgap was divided into a part that protects the left and right upper arms and a part that protects the chest, so that the unexcavated head and neck cover of the helmet can be protected to the shoulder. In addition, in the case of Chalgap (札甲, lamellar armor), the Oejungsik (外重式, folded from outside to inside) is mainly used, but it is peculiar that Naejungsik (內重式, folded from inside to outside) is used in Sangbakgap of Jaemaejeong armor. It is presumed that this was used as a method to ensure that the armor were closely attached to the human body. In order to design with the parade armor of Gochwidae in Gyeongju based on the reproduced Jaemaejeong armor, the designer's imagination and historical work of the times were involved due to the characteristics of performance costumes. Reproduced armor as a cultural content should be considered indispensable to simplify and lighten clothing suitable for performances based on the excavated historical armor.

We are surrounded by so many images these days. These images have their own meanings and have an effect on our subject, whether consciously or unconsciously. Michel Foucault disclosed that upon closer examination the rationalism deeply rooted in Western society was not made autonomously but involuntarily by heteronomous power. Because the emotion of image within this relationship can be effectively conveyed just through its being seen, the image has been used for controlling and mustering people through the adjustment of its meaning by power. With the advance of technology and media of today, the image in this visual power is out of the object for reproduction, and then forms a new paradigm of manipulation, transformation and reproduction and is being changed to the formation of Panopticon power and its corresponding relationship.

This paper investigates how digital technology innovates the aesthetic ontology of film images. The modern civilization of computer and internet bring about the new ontology of film images. Digital hybrid image expands the contradictory combination of physical reality and filmic fantasy. It is inevitable to recount Walter Benjamin' s concept of mechanical reproduction in the age of digital cinema. The modern condition of image arts changes the concept of mechanical reproduction to the logic of digital configuration. In addition, computer simulation innovates the film aesthetics of montage to the aesthetics of digital collage. The technological and aesthetical development of computer simulation and internet network leads to the new ontology of digital hybrid images. This study suggests a new theoretic point that the aesthetic ontology of digital hybrid images leads to the expansion of filmic fantasy and expression.

This study analyzes the creation process of local cultural contents that appears in the Maeul-mandeulgi by utilizing the "Village Rituals" handed down from village. The purpose is to analyze the social values and meanings they represent. For this purpose, a qualitative research method using Chilgok-gun Yeong-ori was applied and analyzed through Lefebvre's the production of space theory. Residents began to recognize the necessity of projects such as Maeul-mandeulgi to overcome the community crisis, and attempted to change the perception of existing village rituals. Residents began to recognize the need for projects such as Maeul-mandeulgi to overcome the community crisis, Attempts to change the perception of the existing village rituals resulted in spatial practice. The new cultural contents were created by adding a playful element to the existing Cheonwangje, and thereby strengthening the identity of the village. This resulted in the reproduction of the village as a new cultural space, but it showed the reproduction of the space in which the alienation occurred due to excessive physical expansion. However, through this process, villagers increased their sense of belonging and increased their satisfaction, which showed the process of being produced as a space of representation that strengthens the sense of community.

The rectnt studies on the learning of the scientific concepts have suggested that most students have misconceptions related to the contents to be learned and that those misconceptions exert their influences on the subsequent learning of the content Those facts necessitate the identification of the misconceptions before the instructions and the preparation of the instructional materials based on those misconceptions identified. Several studies also revealed that such biological areas as cell division, reproduction and fertilization were ranked among the most difficult areas for high school students to learn. Therefore, this study had its triple objectives as follows: (1) Identification of misconceptions in such areas as cell division, reproduction and fertilization. (2) Investigation of the current high school biology textbook I's as the sources of those misconceptions. (3) Development of teaching materials based on the misconceptions identified and the problems in the textbooks analyzed. This study identified several misconceptions held by high school students of biological concepts related to the conceptual areas of life-continuity, and found the problems in learning of the high school biology textbooks. Based on the misconceptions and the problems, a teaching/learning model and its content material were developed at the final course of this study.

In order to investigate the appropriate processing season and the production of high value-added products in ark shell(Scapharca subcrenata) cultured at the south coast of Korea, the foot muscle, mantle, and adductor muscle were analyzed for moisture, protein, fat, ash, and glycogen using specimens collected bimonthly from December 1994 to December 1995. The contents of moisture in foot muscle and mantle increased in spring season, however their proteins decreased in same season. Glycogen and fat in foot muscle, mantle, and adductor muscle were most abundant in June, just before the spawning season, but all the cmponsnts dwindled during spawning season. The other hand, the contents of ash in tissues were almost the same level through the year. Thus, the contents of moisture, protein, fat, and glycogen were almost the same level through the year. Thus, the contents of moisture, protein, aft, and glycogen were fluctuated by season. Especially, they showed a marked seasonal variation at before and after sparning season. So, a major cause of seasonal variation in S. subcrenata would be connected with a period of reproduction and spawning season.

Since passive information users in mass media era became active information producers in this Internet era, an enormous amount of education contents has been created. As people use different production and reproduction tools even for the same content, however, user-created contents (UCC) do not have compatibility among them, which leads to other problems too. In order to solve these problems, this study proposes "a platform in UCC production environment based on standard specification, which will enhance interoperability among contents." We expect that this platform will help design Contents Publication and Management System (CPMS), which minimizes jobs required to be done repetitively for contents up-loading or transfer and thus enables easy contents sharing and management.

This study analyzed on alloys and by-product samples produced through the reproduction experiment of bronze mirror with geometric designs. The alloy ratio used in the first and second reproduction experiments was based on the analysis results of bronze mirror with geometric designs(Cu 61.68%, Sn 32.25%, Pb 5.46%) which is the national treasure No. 141. As a result of portable X-ray fluorescence analysis on the raw materials used in the reproduction experiment, the contents of copper raw materials were 98.85 wt% for Cu, tin raw materials were 99.03 wt% for Sn, and lead raw materials were 70.19 wt% for Pb, and 21.81 wt% for Sn. Sn and Pb were added 5 wt% more considering the evaporation amount of tin and lead during alloy melting. The result produced by the first reproduction experiment were 58.75 wt% for Cu, 36.87 wt% for Sn, 4.39 wt% for Pb, and the other result produced by the second reproduction experiment were 58.66 wt% for Cu, 35.89 wt% for Sn, and 5.50 wt% for Pb. The composition of the components was about 3.00 wt% in Cu and Sn respectively, and the microstructure was similar to the previous studies because the δ phase was observed mainly. The results of this study will be used as basic data for the materialistic characteristics of ancient bronze mirror in the future.
