  • In this paper, two specially designed associative mapping memories, called Associative Mapping Elements(AME) and Multiple-Digit Overlapping AME(MDO-AME), are presented for learning of nonlinear functions including kinematics and dynamics of robot manipulators. The proposed associative mapping memories consist of associative mapping rules(AMR) and weight update rules(WUR) which guarantee generalization and specialization of input-output relationship of learned nonlinear functions. Two simulation results, one for supervised learning and the other for unsupervised learning, are given to demonstrate the effectiveness of the proposed associative mapping memories.

  • As dual port memories are being frequently used, test and diagnosis for dual port memories becomes more important. In this paper, anew diagnosis algerian which can classify faults in detail when the fault is detected during test process is developed. The new algerian increases its efficiency by using the information that can be obtained by test results as well as results using additional diagnostic pattern set. In addition the algorithm can diagnose various fault models for dual port memories.

  • This paper proposes a test algorithm that can detect and diagnose all the faults occurring in dual-port memories that can be accessed simultaneously through two ports. In this paper, we develop a new diagnosis algorithm that classifies faults in detail when they are detected while the test process is being developed. The algorithm is particularly efficient because it uses information that can be obtained by test results as well as results using an additional diagnosis pattern. The algorithm can also diagnose various fault models for dual-port memories.

  • This paper proposes a memory testable code called MTA(Memory TestAble) code which is based on error correcting code technique for testing functional faults in semiconductor memories. The characteristics of this code are analyzed and compared with those of conventional codes. The developed decoding technique for this code can reduce the decoder circuits up to 70% and obtain two-times faster decoding speed than other codes such as hamming code or Hsiao code. The MTA code is eccectively applicable to parallel testing of semiconductor memories because it has the same information length and parity length. It can detect from single error functional faults to triple error in semiconductor memories.

  • Recently, an SSD with hybrid buffer memories is actively researching to reduce the overall latency in server computing systems. However, existing hybrid buffer policies caused many swapping operations in pages because it did not consider the overall latency such as read/write operations of flash chips in the SSD. This paper proposes the clock with hybrid buffer memories (CLOCK-HBM) for a new hybrid buffer policy in the SSD with server computing systems. The CLOCK-HBM constructs new policies based on unique characteristics in both DRAM buffer and NVMs buffer for reducing the number of swapping operations in the SSD. In experimental results, the CLOCK-HBM reduced the number of swapping operations in the SSD by 43.5% on average, compared with LRU, CLOCK, and CLOCK-DNV.

  • Bonjeong-tong(本町通) which was originated from Japanese place name and commercial center during Japanese colonial period speaks for downtown in the urban Korea of today. This study tries to investigate a variety of place memories that have been layered in Bonjeong-tong in the case of Chungmu-ro and Myeongdong area in Seoul, Korea. The author settles the concept of 'place memory' from the viewpoint of the discipline of human geography, and reconstructs place memories of Bonjeong-tong by three folds of layers focusing on the multilayeredness and the contestedness of place memories which have been piled up in Bonjeong-tong; 'the symbol of colonial power' vs. 'the emblem of modernization', 'the heart of monetary capitalism' vs. 'the ground of humanists and artists', 'the space of fashion' vs. 'the place of identity'. As a result, the author places emphasis on that a place like Bonjeong-tong in itself within a city is a sort of palimpsest, and suggests that therefore it is necessary to adopt a vertical approach not a horizontal one for the study on urban space in future.

  • The media, traditionally, serves to reinforce one's limited memory and transform those personal memories of society's members into collective memories. Notably, the mass media collects countless pieces of personalized memories for the creation of collective memories. Through the process of recollecting as well as recreating the past in the present, mass media exerts influence on the means the public appreciates and understands the history. Although numerous new medias like Internet overflows in today's society, television continues to stand firm as the salient means to construct the memories in daily lives. In this context, the research aims to analyze the televised news as the principal agent of memory producer to determine through which memories it recreates the $5{\cdot}18$ in today's media. The analysis of news values clarifies that every government placed distinctive news values on $5{\cdot}18$ within its historical context. Even so, such values were often fixed based on its relations to the existing political issues. Furthermore, through the discourse analysis, this research concludes that today's coverage of $5{\cdot}18$ is softening and becoming conventional.

  • Previous studies have demonstrated that childhood memories can impact self-concepts. However, scant research has been conducted to determine whether and how the activation of childhood memories relates to the motivation of prosocial behaviors. Thus, this study investigated whether childhood memories facilitated prosocial behaviors through implicitly activating moral purity and how differently an abstract (vs. a concrete) construal level of autobiographical memories evoke prosocial intentions. According to the results of Study 1, the participants in the experimental condition of childhood memories were more motivated to perform prosocial behaviors than those in the controlled condition of recalling recent mundane activities. In the experimental condition, moral purity was activated more strongly than in the control condition. Study 2 demonstrated that participants in the "concrete" condition of childhood memories tended to the lower levels of prosocial motivation than those in the "abstract" condition wherein they were counting and describing good deeds from their childhood in detail. These results indicate that different construal levels (abstract vs. concrete) can mediate the relationship between childhood memories and prosocial behaviors. This study contributes to extending previous research regarding the determinants of motivating prosocial behaviors in cognitive processes.

  • The origin of texts we refer to as literary or artistic may be imagination, but many are based on experiences. In fact, experiences can be the source of artistic imagination since imagination often builds upon experiences. Therefore, the act of verbalizing human experiences using them as raw material can become a great form of art. Transforming past experiences into stories and infusing them with vitality inevitably requires a creative process of reconstruction, which is essentially a literary process. As such, 'Personal Narrative' holds significance as a literary process that weaves facts into stories and shapes them into forms. Individual experiences are stored as personal memories, and these 'personal memories' continuously generate stories. Collections of individual stories are stored as multiple memories, which gradually form 'collective memories' with distinct social and cultural inclinations through the passage of time and invisible yet potent societal and cultural censorship. The problem lies in the fact that individuals may tend to align their own memories with the inclinations of collective memory rather than simply recalling what they personally experienced. In the context of actual history, personal memories and collective memories communicate with each other, producing non-fictional content close to reality and sometimes manifesting as fiction content enriched with imagination. 'Personal Narrative' holds a significant genre as one genre of non-fiction content within our culture.
