In this paper, we proposed a way to improve performance of GP-GPU by deletion of superscalar issue from its original form. At first, we simplified the structure of stream processor in order to eliminate superscalar issue. Under this condition, preservation of hardware size and increasing of thread number were followed by functional improvement of GP-GPU. As the number of thread was getting larger, we proposed the new model of warp scheduler which adjusts the group of thread. This superscalar issue-deleted warp scheduler transferred the instructions to warp which was activated by Round Robin Scheduling. Performance comparison was conducted by Gaussian filtering and the results indicated that our newly designed GP-GPU showing 7.89 times better in its performance than original one.

Traditional paper records have to be preserved in the original form to ensure the authenticity. On the other hand. electronic records have to be continuously changed in content itself or metadata to be preserved in long-term period, so the proof of the legality of each change made so far and the proof of the protection against all the illegal changes are the essential. to ensure these requirements. We need some functions including the authentication of original captured records. the protection of records against the loss or forgery, the authentication of preserved records, and the treatment of authentication-failed records. This paper explains the fragility of authenticity for electronic records, identifies the functions needed, suggests the implementation idea, and describes the overall management polity for electronic records to ensure the authenticity.

$Chos{\check{o}}n$ Dynasty was governed by the words of king, however, if they were not announced by the form of public document, they were useless. Therefore, the form of public document was the symbol of governing activity, and it was very important to manage the public record in operating the nation affairs. However, the point we should consider is that $Chos{\check{o}}n$ Dynasty, in the case of managing the public record, edited 'the original' instead of preserving them. And so, the preservation of the public record was deeply related to the editing of history. In Late Korea dynasty, the management of the public record got into utter confusion and so many troubles were occurred. In order to resolve these problems, the movements which innovated the public record managements system was gradually extended. This movements were continued in $Chos{\check{o}}n$ Dynasty. Finally, through the several modification procedures, the rules of public record management were legislated by 'Kyong Kuk Dae Jeon'(經國大典). Especially, by laws of 'Kyong Kuk Dae Jeon', not only the daily records of Secretary Department(承政院) but also the important documents which was related to the government branch should be booked in the last decade of the year and the number of the books had to be reported to the king. This rule made certification of the fact that the king was the last confirmer of the public record management. In addition, through the procedure of printing the record of the national affairs, and the diplomatic once in three years, and then preserving that public record in the National Department(議政府), other departments responsible and the archives, the National Department practically took part in the public record management. The management system was also changed in order that the public record was virtually used and consulted before taking the procedure of immortal preservation. All public documents were classified by the definite rule and filed in a same volume. After classifying and filing, certainly, for making convenience of reference and application of public record, records were indicated by the paper card. It may be that, after the step of reference, application and indicating, the public documents were gradually transferred to the next step. In these procedures, Early $Chos{\check{o}}n$ public documents system was confirmed.

The museum starts from drawing many visitors by opening remarkable exhibitions, and finally aims to realize the social and educational value. However artifacts on exhibition have antithetic conditions like limitation of collection, problems of preservation, etc. Already the museum exhibited paintings and fine arts reproduced with complete fidelity, so artistic artifacts have meet the aims of exhibition. we would like to make an alternative proposal about costume relics in this way. Costume relics need to reproduce in two ways. The one way is to reproduce with complete fidelity and the other way is to restore the original form. The reproduction and restoration need a concrete survey, historical research, textile like artifacts. Furthermore it is important to reconstruct breakage and discoloration. Permanent exhibition consisted of reproductions helps appreciating as well as protecting artifacts, so exhibition effect will be enhanced.

In the historical trend of Korean dance, Korean traditional dance continues to evolve through the transition to stage dance due to the modernization process, the tangibleization of traditional dance, the reconstruction or re-creation of traditional dance. Moreover, the trend of reconstruction and re-creation of traditional Korean dances has been common in traditional dance performances since the 2000s, with two directions: performance of original restoration and preservation and evolution of traditional dances. Therefore, this study is a study of the change in the form of traditional dance and the process of the evolution of traditional dance, and among them, the change of the traditional paradigm of the Lee Dong-an Ryu Jin-so dance. The paradigm shift of traditional dance was staged through the trend of the times to the extent that the original's meaning and form were not undermined, and we can recognize that the paradigm of traditional dance is a way of introducing new aspects as a way of transmission.

Culture Technology is the basic technology which produces cultural contents in a narrow sense. All nations do their best in order to create new contents which can form international and cultural sympathy. If a variety of contents are created by applying Korean proper cultural heritages, they will be creative and competitive internationally. Therefore, technology of original cultural restoration is an essential and crucial skill. In this paper, 'gilt bronze dragon-phoenix ring-pommeled sword', a cultural heritage of baekje age, will be restored to the original form digitally on the basis of three-dimensional shape-information processing technology and the scientifically analyzed data. First of all, data from three-dimensional scanning is revised using stuffing and smoothing methods after sampling, extracting characteristics, and align. Then, they are modeled in a curved surface with NURBS and B-Spline. Secondly, textures are edited by estimating the color of components and the quality of materials, and then they are mapped. Original form model which was made was revised and corrected by specialists' examinations. The digitally revised ring-pommeled sword was combined with information technology, and it can be used to revise damaged cultural heritages by constructing formal database of ring-pommeled sword with regard to age, area and type. It can be also used as educational contents in archaeology or preservation science and cultural contents such as movies, broadcasts, games, animations and so on.

Natural Monument is a designated cultural property as part of the country. According to Article 2 of the Cultural Properties Protection Act, a national, ethnic and global heritage artificially or naturally formed, with a great historical, artistic, scientific and landscape significance is defined as a cultural heritage. Animals, plants, topography, geology, minerals, caves, biological products and special natural phenomena, having a great of historic, scenic and scientific value, are defined as the monument. According to Article 3 of Cultural Properties Protection Act, the conservation, management and utilization of National Heritage should be kept intact in its original form. So, Natural monuments are managing as retained its original form under the Basic Principles of current law. The highest population of coniferous tree in natural monument plant is ginkgo tree including 22 objects, followed by pines, junipers that order. And in case of broadleaf tree, there are zelkova trees, retusa fringe trees, pagoda trees, cork oaks, silver magnolias and etc. There are many of reported efficacy in available natural monument plants. The efficacy of plant species on pharmaceutical like anti-cancer, anti-diabetic, anti-obesity, antioxidant activity, neuroprotective, improves cholesterol, anti-inflammatory, liver protection and anti-bacterial efficacy, on cosmetics and beauty like the inhibiting formation of skin wrinkles, whitening effect, variety of materials and the efficacy of the proposed utilization of its various papers and etc have been widely reported. Before the Nagoya Protocol enters into force, the future role of the National Research Institute for Cultural Properties Administration of Cultural Heritage should be obtain a legal right to manage the social, cultural and national natural monument with emotional value to the plant genetic resource as a natural monument efficient ways to study and preserve traditional knowledge biological resources by securing a claim to the sovereignty of the material will be ready.

Historically, Korea has made and weaved beautiful jewelry based on delicate metal craft technique. Especially jewelries in Chosun dynasty among these jewelry shows practicality, fanciness and social symbolism at the same time, which is one of representative cultural origins to express characteristics of Korean culture. Since jewelry of imperial princess YEONG, an object of a study herein, was made for a court ceremony although it is an artifact of the end of Chosun dynasty after the time of enlightenment, it is expected be made based on traditional shape and standard in accordance with strictly respected court dress code in Chosun dynasty. It is also an important data of research for a court style and system as well as its artistry in its diversity of type, preservation condition similar to original form and its producers who are master craftsman parted in Sang-Uiwon (an institute in charge of dress and accessaries of court) at the end of dynasty. Thus, a study herein aims to research formatively valuable 11 selected jewelries among jewelries of imperial princess YEONG used at the end of Chosun dynasty, and search for industrial application method with digitalization of the shape and design and preservation of original form of traditional culture. Moreover, in accordance with proposing design data through review of traditional women jewelry, it aims to suggest possibility of application into modern jewelry design and cultural industry.

This paper proposes a systematic methodology that could be used to decide which one shows the best performance among space filling curves (SFCs) in applying lower-dimensional transformations to histogram sequences. A histogram sequence represents a time-series converted from an image by the given SFC. Due to the high-dimensionality nature, histogram sequences are very difficult to be stored and searched in their original form. To solve this problem, we generally use lower-dimensional transformations, which produce lower bounds among high dimensional sequences, but the tightness of those lower-bounds is highly affected by the types of SFC. In this paper, we attack a challenging problem of evaluating which SFC shows the better performance when we apply the lower-dimensional transformation to histogram sequences. For this, we first present a concept of spatial locality, which comes from an intuition of "if the entries are adjacent in a histogram sequence, their corresponding cells should also be adjacent in its original image." We also propose spatial locality preservation metric (slpm in short) that quantitatively evaluates spatial locality and present its formal computation method. We then evaluate five SFCs from the perspective of slpm and verify that this evaluation result concurs with the performance evaluation of lower-dimensional transformations in real image matching. Finally, we perform k-NN (k-nearest neighbors) search based on lower-dimensional transformations and validate accuracy of the proposed slpm by providing that the Hilbert-order with the highest slpm also shows the best performance in k-NN search.
