In this paper, we introduce the UTOPIA Smart City Security Management System which manages a user authentication for smart cities. Because the smart city management system should take care of huge number of users and services, and various kinds of resources and facilities, and they should be carefully controlled, we need a specially designed security management system. UTOPIA is a smart city system based on ICT(Information and Communication Technology), and it has a three tier structure of UTOPIA portal system, UTOPIA processing system and UTOPIA infrastructure system. The UTOPIA processing system uses the smart city middleware named SmartUM. The UTOPIA Smart City Security Management System is implemented in the application security layer, which is the top layer of the SmartUM middleware, and the infrastructure security layer, which is the lowest layer. The UTOPIA Smart City security management system is built on the premise that it supports all existing user authentication technologies. This paper introduces the application security layer and describes the authentication management in the application security layer.

In the ACE2000 MPLS system, MPLS Interface Module(MIM) is composed of an ATM Interface Module and a HFMA performing a packet forwarding. In the MIM, the HFMA RSAR receive cells from the Physical layer and reassemble the cells. And the IP Lookup controller perform a packet forwarding after packet classification. Forwarded packet is segmented into cells in the HFMA TSAR and transfer to the ALMA for the transmission to an ATM cell switch. When the MIM make use of an ATM Interface Module, it directly connect the ALMA with a PHY layer using the UTOPIA Level2 interface. Then, an ALMA performs Master Mode. Also, the HFMA TSAR performs the Master Mode in the MIM. Therefore, the UTOPIA-L2 Controller of the Slave Mode require for interfacing between an ALMA and a HFHA TSAR. In this paper, we implement the architecture and cell control mechanism for the UTOPIA-L2 Controller supporting Multi-ports.

If we take account of the 'Architectural Tradition' which aims a construction of better environment, we can see that this tradition has ended historically toward Utopia. It is a continual trend from ancient Greece to contemporary epoch in each transitional periods and especially in the Renaissance Era. Utopia is an ideal commonwealth in which inhabitants exist under perfect conditions, ideally perfect places or state of things. The plans of utopia are complete projects of image, its goal is an social, political and economical improvement according to the eras. Its plans are characterized by rigid geometrical pattern as circle and square, which contain generally center axis symmetry enclosure. Recent urban and architectural circumstances no longer reflect utopian visions. Since the latter of the 20th century, it appears dystopia on the contrary. Therefore, the utopian ideal city and architecture describes characteristics of the era unlike the continuity of its concept.

The current study aims to 1) investigate how fashion is perceived in societies that utopian novels were born and 2) what fashion means in utopian worlds by content analyzing two utopian novels, Thomas More�s Utopia and William Morris�N ews from Nowhere. The analyses of More�s Utopia and Morris�s News from Nowhere revealed that both utopian societies made corrections from our (imperfect) societies to increase happiness of people. Dresses of those two utopian societies were described as comfortable, pleasant, and attractive. There was a difference in design in that More considered simple and natural designs as the best whereas Morris considered human processed, labor intensive designs as the most attractive. However, fashion did not exist in either utopian world. It is reasonable to say that utopian societies were anti fashion in general due to the conflicting natures of fashion and utopia.

ACE 2000 ATM 교환기를 이용하여 MPLS 교환기를 구현 시, ATM 가입자 및 중계선을 수용하여 스위치와 정합 기능을 수행하는 AIM(ATM interface module)에 IP 패킷에 대한 룩업을 수행하여 ATM 스위치로 패킷을 포워딩하는 HFEA(High performance Forwarding Engine board Assembly)를 연동하기 위해서는 UTOPIA Level2 연결이 요구된다. 그러나 HFEA 에서 622Mbps 급 성능의 MXT4400(SAR) 칩은 TSAR(Transmit SAR)로 운용 시 Master모드로 동작하게 되고, AIM 모듈 또한 Rx에서 Master모드로 동작하기 때문에 이들을 연결하기 위해서는 양 모듈간에서 Slave 모드로 동작할 수 있는 UTOPIA Controller가 필요하게 된다. 이에 따라 ALMA(AW Layer Module Assembly)칩과 HFEA TSAR 사이에서 데이터를 전달하는 UTOPIA Controller를 Xilinx를 이용해 FPGA로 구현하였다.

If we take account of the 'Architectural Tradition' which aims a construction of better environment, we can see that this tradition has ended historically toward Utopia. And the concrete concepts of utopia mainly started on the Renaissance periods. The Utopias were described well in the literatures which contained particularly three representative utopian books in Renaissance period. The one was the most famous novel by Sir Thomas More and the other were by Tommaso Campanella and by Francis Bacon. These novels expressed ideal commonwealths in which inhabitants exist under perfect conditions, ideally perfect places or state of things. The plans of utopia are complete projects of image, its goal is an political, social and economical improvement according to the eras. Their utopias mostly had characteristics as follows; their shape of islands were almost circle, their shape of cities were rectangularity or circle and attached importance to geometrical compositions, their structure of cities were self-sufficiency in closed spaces and their architectural characteristics were uniformity, simplicity and non-ornament. And these architectural characteristics are urban and architectural traditions in communist countries. Also their utopian novels had not much explanations to daily lives of people like as birth, death, relative, mental conflict or authority, money, art. So their utopian novels were not practical and had inappropriate aspects.

NP Forum에서는 다양한 밴더의 네트워크 프로세서와 스위치 패브릭간에 물리적 인터페이스를 제공하기 위해 CSIX-L1(Common Switch Interface-Level 1 )인터페이스를 표준화하였다. IBM 네트워크 프로세서는 MPLS 및 VPN, VLAN, Security, Ipv6와 같은 다양한 어플리케이션과 TBI. SMII CMII. POS bus등 다양한 가입자 인터페이스를 지원하며, L2 기 반에서 2.5Gbps 이상의 패킷 처리를 수행하기 때문에 많은 시스템에 사용된다. 그러나 IBM네트워크 프로세서는 스위치 인터페이스로 DASL인터페이스를 사용한다. 따라서 DASL인 터페이스와 CSIX-L1 인터페이스를 정합하기 위해서는 IBM UDASL칩을 이용해 DASL인 터페이스를 UTOPIA-L3인터페이스로 변환해야 하며, 이것을 다시 CSIX-L1인터페이스로 변환해야 한다. 따라서 본 논문에서는 UTOPIA-L3인터페이스 패킷과 CSIX-L1인터페이스 프레임을 상호 변환하는 모듈을 설계하였으며, 32비트 데이터 버스와 최대 125MHz로클록을 사용해 최대 4Gbps의 패킷처리를 제공하도록 구현하였다. 또한 스위치 패브릭의 특정 포트에서 과잉 트래픽 전달로 인해 발생할 수 있는 블로킹을 방지하기 위해 네트워크 프로세서에게 3개의 Priority／최대 64개 포트수의 VOQ(Virtual Output Queue)를 제공하는 기법에 대해서 기술한다.

The concept of 'utopia' in Korea was formed in the early 20th century. 'There isn't in this world but good world' could be found using science and it was an ideal place for science to realize in the 1900s of Korea. Utopia was emphasized as an ideal world of fantasy in the 1920s. It was an ideological world wherein socialism was realized by a purposeful science. Utopia, conversely, was the history of scientific socialism defined as past example of communism that could not be implemented but was fancied. There were works suggesting that it was a dark dystopia such as Society after 800,000 years written by H.G. Wells or Artificial Worker by Young-hee Pak, but there were implied at the will of utopia.

Idealistic Rural Community Movement(Rural Utopia Movement) was one of the most powerful rural community movements in the world. Regardless of the East or the West, people started dreaming of happiness through idealization of rural communities as early as several centuries ago and have tried to implement this as a social movement to make the dream come true. Western rural utopia movement started when Thomas More published "Utopia" in England in 1516 and spread to many other countries in various forms. Chinese version of rural utopia was well portrayed in both "So Gook Gwa Min" (small population in a small country) written by Lao-tzu in the 6th century B.C. and "Arcadia" by Do, Yun-Myoung in the $4^{th}$ century. In Korea, the rural utopia people pursued was vividly described in the following three. First, Yul Do Gook portrayed in "Hong Gil Dong Jun" written by Hu Gyoon. Second, Gong Do portrayed in "Hu Sang Jun" written by Park Ji Won. Third, Sin Min Hwe's rural utopia movement made in the entire nation as well as Manchuria and America so as to save the country, which contributed to protecting the rural communities and arousing hopes in farmers by making a good model. This movement is especially important in that it became the foundation of modernization of Korea through Ga Na An(Canaan) Farmers' School and Sae Ma Ul Woon Dong(New village movement), which were heavily influenced by continued Sin Min Hwe's rural utopia movement.

This study contemplates the utopian landscape recognized by the scholars with twenty three pieces of 'travel record'. Consequently, five key words - Mureungdowon(武陵桃源), Byeolcheonji(別天地), Dongcheon(洞天), Chonghakdong, Eungeoji(hermitage) - are chosen for comprehending the utopia and their landscape characteristics are organised as follows. Mureungdowon in Jirisan Mountain which the scholars dreamed of is a flatland with the full energy for local vegetation and domestic animals in the mysterious and deep gorge. This utopia eventually reflects the rural landscape. Byeolcheonji is a utopia combining the concept of a fairyland and beautiful scenery. The scholars also used the term 'Dongcheon' for naming the enclosed landform which is suitable for seclusion and defining the some areas of beautiful scenery. Cheonghakdong, which is set only in Jirisan Mountain, has been formed by the stone scenery of gorges and Buril waterfalls around the whole area of Burilam Hermitage, the vegetation scenery of pine trees and bamboos with the legend of Choi Chiwon and his engraved inscription on a rock. Adding to the utopia passed down, the scholars perceived the village with geographical features with back to the mountain and facing the water, the river practising the trade, the flatland enclosed by bamboo forests, the vegetation mainly consisting of fruit trees and beautiful scenery as the utopia realized on earth. It is equivalent to the world of human beings laboring appropriately and living in Mother Nature. As mentioned above, this study has significance for apprehending the relevance between the culture of strolling in the mountains by the scholars of Joseon Dynasty and the fairyland and explaining the various traditional utopias from the inherited concepts from China to the naturalized realistic utopia.
