Data Distribution Service (DDS) is a communication middleware that supports a flexible, scalable and real-time communication capability. This paper describes several techniques to improve the performance of DDS middleware. Detailed events for the internal behavior of the middleware are defined. A DDS message is disassembled into several submessages of independent, meaningful units for event-driven structuring in order to reduce the processing complexity. The proposed technique of history cache management is also described. It utilizes the fact that status access and random access to the history cache occur more frequently in the DDS. These methods have been implemented in the EchoDDS, the DDS implementation developed by our team, and it showed improved performance.

This study examines a study of communication factor in the Chinese augury bone, as a communication text, a communication history text and a communication thought text, in terms of sender message channel audience effects, interdisciplinary research. In many respects, it is generally accepted that the Chinese augury bone have been the generic references of the Oriental culture. Based on various research results about The Chinese augury boney as a communication text, this paper explores factors of communication text related with meta-communication as the definition of communication and a structure of communication, a method of communication. The Chinese augury bone consider graphic element as communication tool, its manager as sender or communicator, the record as message, the bone as channel, its reader as audience, text understanding and behavior as effects, the augury bone producer as journalist, the tying bone in a bundle as old style book. In the Chinese augury bone, one property of communication thought is that the political ideology, which is related to the strong and weak of the graphic style and determines the naming method of kings.

This paper presents a landscape design for the citizen plaza around the ˝Woojeongchongkuk˝(the 1st Korean postal building) where the ˝Gapsinjeongbyeon˝(1844 coup d´etat) occurred and which was once used as the ˝Jeoneoigam˝(a palace hospital). The site is located in 39 Kyeonji-dong, Jongno-gu, Seoul, and of which area is about 2,013$m^2$. The landscape design goals are to build traditional spaces which fit the traditional buildings and where people feel the old atmosphere; to build interesting spaces where people can learn the post and telegraphic history; and to build nature-friendly green rest spaces in the city. To achieve these goals, symbolic, traditional, educational, historical, and environmentally-friendly concepts are developed. With this concept the space is divided into two axis of the pst and telegraph of Korea. Along the two axis the Postage Stamp ˝Madang˝(yard), the Letter Garden, the Telegraphic ˝Ddeul˝(garden), the Communication Plaza, and the ˝Jeoneoigam˝(old palace hospital) and the ˝Gapsinjeongbyeon˝(1884 coup d´etat) Memorial Place are arranged. The Postal Stamp Madang which symbolizes the first Korean postage stamp is a space for studying history and evolution of stamps in Korea. The Letter Garden which symbolizes and formalizes a letter paper is composed with white bamboo trees which are planted linearly and long granite benches on which famous letters are carved. In the Telegraphic Ddeul which symbolizes the telegraph, the history of the telegraphic instrument and the telephone is exhibited. In the Communication Plaze which symbolizes future post and telegraph service extending to the world, the images of satellite communication, internet, webmail etc. are exhibited. The Jeoneoigan, and the Gapsinjeongbyeon Memorial Place is for memorializing the historic place and events. Throughout the whole place, various models and ceramic picture tiles about the post and telegraph and exhibited for effective education. In conclusion, sustainable management schemes for the site are suggested.

As collaborative design and configuration design are of increasing importance in product development, it becomes essential to exchange the feature and parametric CAD models among participants. A history-based parametric method has been proposed and implemented. But each translator which exchanges the feature and parametric information tends to be heavy because to implement duplicated functions such as the identification of the selected geometries, mapping between features which have different attributes. Furthermore. because the history-based parametric translator uses the procedural model as the neutral format, which is the XML macro file, the history-based parametric translators need a geometric modeling kernel to generate an internal explicit geometric model. To ease the problem, we implemented a shared integration platform, the TransCAD. The TransCAD separates translators from the XML macro files. The translators for various CAD systems need to communicate with only the TransCAD. To support the communication with the TransCAD, we exposed the functions of the TransCAD by using the Automation APIs, which is developed by Microsoft. The Automation APIs of the TransCAD consist of the part modeling functions, the data extraction functions, and the utility functions. Each translator uses these functions to translate a parametric CAD model from the sending CAD system into the XML format, or from the in format into the model of the receiving CAD system This paper introduces what the TransCAD is and how it works for the exchange of the feature and parametric models.

At the turn of the century in which European colonialism was reaching its zenith and modernization was gathering speed, public museums were institutionalized. This paper looks into the part these European modern museums played in territorializing academic disciplines like anthropology and art history. The museums to deal with are the British Museum and the National Gallery in London, Mus?e du Louvre in Paris, and Museumsinsel in Berlin. Rather than in-depth detailed analysis of each museum, the aim is to explore the ways in which these museological institutions interacting with modern disciplines in the wider colonial context objectified other cultures and formulated a framework of the world through classification and comparison of material things, on the basis of the judgement of their artistic values. This exploration is also to rethink theoretical positions and perspectives on the museum in Korea. It is remarkable in Europe that such academic fields as history, art history, anthropology and cultural studies look for new possibilities of museology in conjunction with the recent proliferation of studies on the museum as a medium to construct and deconstruct knowledge. Meanwhile, the mammoth European museums which are often considered a stronghold of museology advocate the 'universal museum' themselves, quite the modern idea but in a revised rendering. Under these circumstances, this paper seeks to shed light on the definition of the museum as an arena in which scholarly discourses about art, culture and history can be created and contested, on the effectiveness of the museum as a communication medium in a postcolonial era, and on the need to pay trans-disciplinary attention to the museum in its broadest sense.

Eoyakwonbang is a collection of prescriptions of Yuyaoyuan, an imperial medical bureau of China. While the first edition of this book does not exist at present, two versions printed in Korea, and one printed in Japan, which is the well-known Gyesasingan Eoyakwonbang have been passed down. Eoyakwonbang is a meaningful text for the history of medical communication between China, Japan and Korea, but research on the different versions and contents of Eoyakwonbang have been insufficient. Out of the 2 versions published in Korea, Eulheja Eoyakwonbang is different from Gapjinja Eoyakwonbang [another version in Korea] and Gwanjeong Eoyakwonbang of Japan, in that the prescriptions are organized, the ingredients are organized according to the amount of each ingredient for each formula, and the amounts are recorded in an accurate manner. On the other hand, the Gapjinja version has many mistakes in the characters and content. The Gwanjeong version has lesser mistakes in characters, but repeats the content error of the Gapjinja version. Eulheja was printed after correction based on the original version or unknown version from China. Gapjinja was re-printed based on the Gyesasingan version, while Gwanjeong seems to have used the Gapjinja version as its original script, as the mistakes made in the Gapjinja version are repeated in the Gwanjeong version as well.

In this paper, we propose schemes of blockchain utilization in tactical communication environment. The military tactical communication environment has similar characteristics with blockchain network such as distributed architecture, decentralization, and the need for data integrity. A communication node constituting a tactical communication network is constituted by a system capable of configuring and connecting a network for each node. When a communication node, having such capabilities, is configured as a node of blockchain network, various functions could be performed. In this paper, we propose utilization schemes of authentication, integrity, record management, and privilege control based blockchain technology. Functions for authentication, integrity verification, and record management need to ensure the stored data and could track history. The requirement of function's characteristics are matched to blockchain which is storing data sequentially and difficult to hack data, so that it could perform functionally and sufficiently well. Functions for authority control should be able to assign different privileges according to the state of the requestor. Smart contract will function when certain conditions are satisfied and it will be able to perform its functions by using it. In this paper, we will look over functions and utilization schemes of blockchain technology which could reliably share and synchronize data in a tactical communication environment composed of distributed network environment.

The networking between the press and elites, and its impact on journalistic activities in fact have been major subjects of scholarly scrutiny particularly among students of elite theory and class theory. This is an empirical analysis of how the press establishes networks with several powers in local community. This study basically examines a set of independent variables, such as the nature of capital and history of local newspapers and explores how the management and elites in the press utilize several social resources and establish networks. Major findings of this study are as follows: To begin with, the networking between local newspapers and elites showes significant differences according to the nature of capital and history of the newspaper. In other words, while the newspapers operated by stock capital revealed high degree of networking with political and financial elites, the newspapers operated by family capital did not demonstrate significant level of networking with particular elites. The shorter the history of newspaper is, the more she tends to be dependent on resources, and feel it imperative to establish strong networks with elites.

We have witnessed the rapid development of information technology in recent years. One of the key phenomena is the fast, near-exponential increase of data. Consequently, most of the traditional data classification methods fail to meet the dynamic and real-time demands of today's data processing and analyzing needs--especially for continuous data streams. This paper proposes an improved incremental learning algorithm for a large-scale data stream, which is based on SVM (Support Vector Machine) and is named DS-IILS. The DS-IILS takes the load condition of the entire system and the node performance into consideration to improve efficiency. The threshold of the distance to the optimal separating hyperplane is given in the DS-IILS algorithm. The samples of the history sample set and the incremental sample set that are within the scope of the threshold are all reserved. These reserved samples are treated as the training sample set. To design a more accurate classifier, the effects of the data volumes of the history sample set and the incremental sample set are handled by weighted processing. Finally, the algorithm is implemented in a cloud computing system and is applied to study user behaviors. The results of the experiment are provided and compared with other incremental learning algorithms. The results show that the DS-IILS can improve training efficiency and guarantee relatively high classification accuracy at the same time, which is consistent with the theoretical analysis.
