The general sensor network uses bundle method to collect fixed information from sensor node. However, this method is difficult to actively cope with major sensing objects in healthcare environment including status and position change of person and change of surrounding environment. In order to support the healthcare environment, certain information should be provided in accordance with the change of status of person and surrounding circumstance and also must cope with the change of network type by movement of person. This paper analyzes LEACH protocol which guarantees effectiveness of network as it constitutes clusters between Agilla model that is a representative multi agent middle ware and surrounding nodes. Based on the result of this analysis, it suggests LEACH_Mobile protocol which guarantees node mobility that is the weakest point of LEACH protocol. Moreover, it designs mobility agent middleware which supports dynamic function change of node and mobility agent module which supports dynamic function change of mobile node as components of LEACH_Mobile routing module. In addition, it is definitely increase performance which in mobile node of transfer data rate through LEACH_Mobile protocol of simulation result.

Although design industry belongs to one of the creative industries and contributes significantly to urban cultural economy based on its cluster formation, researches on design industry are rarely made explicit from the perspective of creative industry cluster. After reviewing the life cycle of design industry clusters in Euljiro and Hongdae Area in Seoul, this study compares these two clusters with respect of diverse dimensions of creative industry cluster such as agglomeration economy, spin-off activities and institutional environments. Research methodology includes the analysis of ?Seoul Business Statistics? and the in-depth interviews with 14 professional designers. The result shows that design industry cluster in Euljiro is close to the traditional industry cluster mainly dependent on printing industry with very limited impact on urban economy, while Hongdae Area develops creative industry cluster by virtue of university spin-offs, art markets, hybrid cultural consumption spaces and the active participation of designers contributing to urban economy in diverse ways. This comparative analysis highlights the importance of various environmental components to encourage creative activities in developing the creative industry cluster.

With its foreign trade rapidly expanding and with economic growth continuing at a substantial rate, China has become the largest container traffic generating country in the world. And with trend of container ships becoming larger and faster, the environment surrounding ports in North-East Asia are rapidly changing. The Yangsan, offshore port for Shanghai, being developed on the islands of Da Yangsan and Xiao Yangsan, some 30km offshore, and connected to the mainland by the six-lane highway Donghai bridge, opened phase one in late 2005 and phase two in 2006 respectively and will have 29 berths by 2012 and be able to handle 15 million TEU. The Port of Shanghai which passed Busan in terms of container volume further consolidated its position as the world's No. 3 port with an annual volume of 21.7 million TEU in 2006 and is likely to have emerged as the biggest container port in the world. The Port of Busan, the world's fifth largest container port, wants to survive as regional hub port. In this circumstance, the strategies of the Port of Busan should be established.

In this thesis, the author elaborates on how acceding to the Eurocentric paradigm-driven dichotomy of the premodern vs. modern engenders a logic bottleneck that debilitates academic efforts to explore the formation of the Korean constitution. Following this logic, the author will add credence to the belief that though the West may have had an influence on the formation of Korean democracy, the institution Korea enjoys today is a result of proactive and self-driven interpretation of those influences through the lens of local tradition. This insight is a prerequisite to understanding the spirit of Korea's First Constitution as a result of Koreans creative translation of Western democracy and Republicanism in the Korean context, and one whose roots lie deep in Confucian Great Harmony Thought. Through this, the thesis aims to offer insight into how Confucian Great Harmony Thought can shed light on the historical background of the spirit of Korea's Constitution.

This study aims at analysing the export competitiveness of the six largest countries which have the highest market share in world automobile market, namely Japan, USA, China, Germany, South Korea and France for the last seven years between 2000 and 2006 in Chinese automobile market by using revealed comparative advantage index(RCA), comparative advantage index by country (CAC) and exporting similarity index(ESI). On analysis of the RCA index, it showed that the export competitiveness of Korean automobile in the world market was high following Japan and Germany, but it ranked the lowest competitiveness among the six trade competitors in Chinese automobile market. In other side, it is also made sure that the formidable competitors of Korean automobile export in global market are Germany and Japan. Therefore, South Korea needs to raise its ability to adjust to improvement of the international competitiveness in exports through close cooperation between government and automobile export enterprise and consistent monitoring about Chinese automobile industry and market.

Recently, the cyber-attacks using botnets are being increased, Because these attacks pursue the money, the criminal aspect is also being increased, There are spreading of spam mail, DDoS(Distributed Denial of Service) attacks, propagations of malicious codes and malwares, phishings. leaks of sensitive informations as cyber-attacks that used botnets. There are many studies about detection and mitigation techniques against centralized botnets, namely IRC and HITP botnets. However, P2P botnets are still in an early stage of their studies. In this paper, we analyzed the traffics of the Peacomm bot that is one of P2P-based storm bot by using honeynet which is utilized in active analysis of network attacks. As a result, we could see that the Peacomm bot sends a large number of UDP packets to the zombies in wide network through P2P. Furthermore, we could know that the Peacomm bot makes the scale of botnet maintained and extended through these results. We expect that these results are used as a basis of detection and mitigation techniques against P2P botnets.

This study aims to investigate how secondary mathematics teachers understand and intend to use textbooks for their mathematics instruction. For this purpose, we developed a set of survey items in order to unpack what the teachers understand the mathematical tasks suggested in the textbooks in terms of the levels of cognitive demand and how they intended to use the tasks in the textbooks for their teaching. Twenty-five teachers participated in the survey. The data from the survey were analyzed. The findings from the data analysis suggested as follows: a) the teachers seemed to closely follow textbooks without attempting to modify the tasks, even when the teachers consider it is necessary to modify textbook tasks to high-level tasks, b) the teachers seemed to be unstable in regards that they admitted themselves very competent for modifying tasks for developing students' mathematical thinking but, at the same time, they were uncomfortable with transforming tasks into cognitively demanding tasks that promote students' mathematical understanding, and c) the teachers appeared to consider textbooks as significant criteria in conducting tests including midterm and final exam. In conclusion, the teachers seemed to intend to follow closely the contents and sequence of mathematics textbooks in their mathematics classrooms.

The purpose of this study is to comprehensively consider the challenge contents enjoyed based on SNS through the concept of Gamification and MDA framework. Regardless of the top-down and bottom-up divisions, in common, the participants show an active figure leading the creation and enjoyment of contents. As a result of analyzing the challenge contents using the MDA framework, the mechanics of 'relative level', 'challenge with expressive purpose', and 'Paidia rules' were found. This leads to the dynamics of participants who express an inner sense of achievement such as 'selection and competition for better expression' and 'selflessness and superiority', creating an environment where they can continuously participate in the challenge contents. Lastly, looking at the aesthetics of the challenge contents, it can be seen that participants are actively forming a play culture that leads the creation and enjoyment of contents. This phenomenon has resulted in breaking down the hegemony of content creation and distribution, which was the responsibility of society in the field of information transmission and commercial advertising.
