This paper suggests a new way to implement high speed AES on Intel Core2 processors and AMD Athlon64 processors, which are used all over the world today. First, Core2 Processors of EM64T architecture's memory-access-instruction processing efficiency are lower than calculus-instruction processing efficiency. So, previous AES implementation techniques, which had a high rate of memory-access-instruction, could cause memory-bottleneck. To improve this problem we present the partial round key techniques that reduce the rate of memory-access-instruction. The result in Intel Core2Duo 3.0 Ghz Processors show 185 cycles/block and 2.0 Gbps's throughputs in ECB mode. This is 35 cycles/block faster than bernstein software, which is known for being the fastest way. On the other side, in AMD64 processors of AMD64 architecture, by removing bottlenecks that occur in decoding processing we could improve the speed, with the result that the Athlon64 processor reached 170 cycles/block. The result that we present is the same performance of Matsui's unpublished software.

Memorability is an indicator of how well a stimulus can be remembered. Studies on memorability have shown that stimulus memorability cannot be explained by the perceptual and semantic properties of a stimulus, suggesting that memorability is an intrinsic property of a stimulus. Though real-world scenes almost always contain multiple objects, previous studies on memorability have mainly tested memory performance using a single stimulus. In the current study, we investigated how multiple stimuli with different levels of memorability interact with each other. Participants were asked to remember a high or low memorability target presented with a high or low memorability distractor in the encoding block. Participants' memory accuracy was measured by a sensitivity index in the testing block. Results showed that a high memorability target was easier to remember. However, the distractor memorability level did not modulate this target memorability effect. The current results support previous studies that showed a highly memorable stimulus does not automatically induce bottom-up attentional shifts.

This paper presents an analog circuit implementation and experimental resuls of the Hopfield type neural network. The proposed architecture enables the reconfiguration betwewn feedback and feedforward networks and employs new circuit designs for the weight supply and storage, analog multilier, nd current-voltage converter, in order to achieve area efficiency as well as function al versatility. The layout design of the eight-neuron neural network is tested as an associative memory to verify its applicability to real world.

디지털보존 시대에서도 종이기록물의 보존은 여전히 그 중요성이 막중하다. 그리고 '세계의 기록유산; Memory of the World; MOW'의 지정은 세계적으로 소멸되고 있는 인류의 기록유산을 보존하고 보호하는데 큰 역할을 한다. 아울러 일본 국내에서 진행되고 있는 역사기록물에 대한 수복(修復) 보존 활동을 상세하게 설명함으로써, 한국에서도 이러한 기록물의 보존측면과 활용측면이 수례(車輪)의 두 바퀴처럼 그 필요성을 각각 인식하고, 종이기록물에 대한 보존활동 사업에 더욱 박차를 가하도록 당부하고자 한다.

This paper describes Declination interpolation method in the application of Digital Magnetic Compass(DMC) with small capacity memory for relatively low-priced system. The purpose of this study is to find accurate declination values using Declination Lookup Table(DLT) and Secular Variation Table(SVT) with the Bilinear interpolation method having four points data only. World Magnetic Model with Gauss coefficients produced by NOAA is used in the calculation of DLT and SVT at desired years. To verify the applicability of the proposed method, the simulation tests and the error analysis are carried out in this work. As results from tests, the interpolation error is within 0.01 degree that is much enough to implement high accurate DMC comparing with commercial DMCs on the market. In summary, the declination interpolation method, proposed in this study, can be useful in the application of DMC.

This dissertation is considered a historic generation that Chinese film $6^{th}$ director remembers through their life. Also it is figured out historic anguish and hurt how it was remembered and appeared in film. They have made actual films through their efforts which are different from the conventional generation. In addition, between memory and oblivion the time's signification in the history is showed how what way can be represented. It was presented the time's anguish through memory's metaphor in Chinese film $6^{th}$ works. Also, it was shown the existence's reality from dream was losing as memory was hiding between desire and despair. Additionally, the self of daily was expressed to unconcernedly accept reality, and its against the unchangeable world's eye and memory. The $6^{th}'s$ films' desire was expressed passive appearance to accept reality with losing dream in these three things; cannot be reality in the process to figure out own natural character, and appearance to keep traditional character, finally gradually changing reality. When $6^{th}$ directors analysis the history as memory, social repression follows family's repression, family's repression brings personal repression, and then repression changes to desire, finally the life as a reaction could be maintained. In conclusion, personal desire was covered for fantasy, and the overcoming figure was represented. Moreover, Chinese face that $6^{th}$ directors have memorized was presented through these sentiments.

Since returning to power in 2012, the second Abe administration has pressured Japanese mainstream media in various ways, from creating the Secrecy Act to forming close relationships with media executives and promoting anti-journalism voices on social media. This article focuses on the growth of a jingoist group called the 'Net-rightists' ('Neto-uyo' in the Japanese abbreviation) on the Internet, which has been supporting the right-wing government and amplifying its historical revisionist views of Japanese colonialism. These heavy Internet users deny Japan's war crimes against neighboring Asian countries and disseminate fake news about the past, which justifies Prime Minister Shinzo Abe's hostile diplomatic policies against South Korea and China. Over the past years, the rightist online discourses have become powerful to such an extent that the editorials of major newspapers and TV reports shifted to more nationalist tones. Who are the Neto-uyo? Why have they emerged from the online world and proliferated to the offline world? Two significant characteristics of new media are discussed to analyze their successful media manipulation: cultural transcoding and perpetual rewriting of collective memories. These characteristics have resulted in constructing and reinforcing the data loops of the 'Daily Us' versus Them, technologically raising current diplomatic tensions in East Asia.

In this paper we propose an intelligent navigation algorithm for real world problem which can build a map without localization. Proposed algorithm operates online and furthermore does not require many memories for applying real world problem. After applying proposed algorithm to toy and huge data set, it does not require to calculate a whole eigenspace and need less memory compared to existing algorithm. Thus we can obtain that proposed algorithm is suitable for real world mobile navigation algorithm.

As the subscription rate to both Internet services and wireless communications services increases rapidly, traffic in the future wireless communications will be dominated by Internet applications. Current research for wireless technology is focused to the multimedia data transmission mainly for the personal computer or notebook whose display which has large display and abundant memory. But in the near future, Internet access request from the handphone or PDA device which is already spreaded in the world will be large. Special handset terminals which has small display monitor, low capacity memory and poor processing power has to be managed differently from torrent wireless communications protocols. So, WAP Forum is organized with wireless handset manufacturers in the world and the standardization process for wireless application is being actively developed. In this paper, basic model and architecture of WAP is introduced and adaptation requirements for change from HTML documents to WML formats are proposed. Also, compression ratio gained in the transform from the existing web documents to WML is shown.
