For the management of a knowledge system, systems that automatically infer and manage scalable knowledge are required. Most of these systems use ontologies in order to exchange knowledge between machines and infer new knowledge. Therefore, approaches are needed that infer new knowledge for scalable ontology. In this paper, we propose an approach to perform rule based reasoning for scalable SHIF ontologies in a spark framework which works similarly to MapReduce in distributed memories on a cluster. For performing efficient reasoning in distributed memories, we focus on three areas. First, we define a data structure for splitting scalable ontology triples into small sets according to each reasoning rule and loading these triple sets in distributed memories. Second, a rule execution order and iteration conditions based on dependencies and correlations among the SHIF rules are defined. Finally, we explain the operations that are adapted to execute the rules, and these operations are based on reasoning algorithms. In order to evaluate the suggested methods in this paper, we perform an experiment with WebPie, which is a representative ontology reasoner based on a cluster using the LUBM set, which is formal data used to evaluate ontology inference and search speed. Consequently, the proposed approach shows that the throughput is improved by 28,400% (157k/sec) from WebPie(553/sec) with LUBM.

Multi-dimensional verbal short-term memory mechanisms are largely divided into the phonological channel and the lexical-semantic channel. The former is called phonological short-term memory and the latter is called semantic short-term memory. Phonological short-term memory is further segmented into the phonological input buffer and the phonological output buffer. In this study, the language performance of each of three patients with similar levels of conduction aphasia was analyzed in terms of multi-dimensional verbal short-term memory. To this end, three patients with conduction aphasia were instructed to perform four different aspects of language tasks that are spontaneous speaking, repetition, spontaneous writing, and dictation in both word and sentence level. Moreover, the patients' phonological memories and semantic short-term memories were evaluated using digit span tests and verbal learning tests. As a result, the three subjects exhibited various types of performances and error responses in the four aspects of language tests, and the short-term memory tests also did not produce identical results. The language performance of three patients with conduction aphasia can be explained according to whether the defects occurred in the semantic short-term memory, phonological input buffer and/or phonological output buffer. In this study, the relations between language and multi-dimensional verbal short-term memory were discussed based on the results of language tests and short-term memory tests in patients with conduction aphasia.

The purposes of this study were to examine the patterns of recalling memories in the series and look into the desires of viewers disclosed in the process. Entering the 2010s, people got to recall their memories from the 1980s and 1990s. Nostalgia and retro became cultural products. What made the series, those depict the pure love, friendship, and family affection of main characters under age in those decades, so popular among the viewers? Finding a repeating pattern in recollection of the past, dating, and family love, the investigator saw that the pattern met the needs of viewers and thus analyzed their desires inherent in the series with a focus on its "narratives" and "characters." Their unique sounds effect and music established a micro-narrative that could be divided, thus allowing viewers to own certain scenes easily, which worked to make "non-existent" memories. Secondly, the series succeeded in capturing the desire of viewers living in the age of neoliberalism to reduce their fatigue from excessive choices by setting the characters in a contrived way and thus presenting the desire of maintaining the stable middle class world with no conflicts and the passive female characters. The recollections provided by the series, in the end, fill the desire and deficiency of the present beyond a simple return to the past.

This study aims to interpret the current landscape design of the place and landscape of memory, such as post-industrial parks and memorials that have an old, aging appearance from an aesthetic perspective. The objects of the study are large parks and open spaces that have collective memories for visitors. Visitors' aesthetic experience from these places and landscapes of memory could be explained by aesthetic concepts such as the sublime, nostalgia, and melancholy. Because these aesthetic concepts are associated with past traumas, visitors may be affected morbidly. However, due to the capability of the media to form an aesthetic experience when visitors visit a given place and landscape, visitors can autonomously adjust the distance to the place of memory and gain an aesthetic experience. The aesthetic experiences through the sublime, nostalgia, and melancholy are based on temporality and irreversibility. Temporality here refers to a characteristic of memory, and time in the place and landscape of memory and is based on the irreversibility of time, as time cannot go back. Both the place memory and the memory that is recalled from the combination with visitor's past memories and knowledge are two major factors involved in the construction of the aesthetic experience in the place and landscape of memory. The results of the present study are meaningful in that this study presents a framework for a better understanding and use of both the place memory and appreciators' memory in the design process of a place and landscape of memory and also criticizes a materialistic approach that fails to take into account the visitors' memories.

To examine the locality of Busan is a precondition of examining documenting localities of Busan. What is the locality of Busan and how can I explore the locality of Busan? These are the research questions of this thesis. Memory is fundamental in making an identity. So local memory is fundamental in making locality. Understanding relations between memory and identity, the author explored the locality of Busan by analyzing memories of Busan. To analyze memories of Busan is to examine historical figures of Busan and Cultural Properties of Busan which are on the website of Busan metropolitan city. The results are as follows : According to the analysis of historical figures of Busan, there are no confucius scholars who came from Busan. However in the age of civilization, Busan has produced some talented people by way of receiving a modern education. According to the analysis of Cultural Properties of Busan, Jung-gu(中區) and Seo-gu(西區) and Yeongdo-gu(影島區) are the spaces of migration. Dongnae-gu(東萊區), Suyeong-gu(水營區) and Saha-gu(沙下區) and Gijang-gun(機張郡) are the spaces of settlement. Dong-gu(東區) has changed from a space of settlement into a space of migration with the opening of the Busan Port as a momentum in 1876.

The documentation of a city can never be complete with only the documentation of the administrative domain, and requires that of its citizens, who are living in the city in different ways. This study attempts to present the documentation of the memories of the citizens, which either have never been produced or have been damaged and thus are difficult to be collected. From the Archival Activist point of view, this study suggests documentary as its research method, in order to leave trace of various experiences of Seoul, which are not recorded in document but are rooted in its people's memories and their daily lives. Documentaries are characterized by their narrative. This can be somewhat arbitrary, but it is due to their narrative that this study suggests documentaries, rather than oral statements, as a new form of method. While, due to its self-historicality, oral records are subject to producing redundant or irrelevant memories, documentaries enable the documentation of data relevant to the topic of collection. First, the study presents the narrative-based archiving, which is the same method of collection suggested by Seoul Metropolitan Archives, and then explores the role and significance of documentary archiving. It further presents the conditions in which documentary archiving is required in the context of narrative-based collection. The study presents the planning and implementation of documentary archiving and introduces one of the three documentaries produced by 2019 Seoul Archiving Project.

This is the study on the 'Theater State' in the Daehan Empire of the Emperor Gochung in the late 1900 with the theatrical concepts of cultural performance theory which has been useful for investigating historical, social, and cultural collective memories and their transformation mechanism in the society. The performance theory is based in the notion, '$Performativit{\ddot{a}}t$', by which the performance can contain vary performance forms. $Performativit{\ddot{a}}t$ is the notion which points up the certain process that can cause the perceptional emotion communication to the performers and audiences in the performance. The spectacle of a society is also understood and presupposed by the $Performativit{\ddot{a}}t$. Generally speaking, the spectacle has been used of explaining the visual cultural experiences in society. Fundamentally, spectacle had resulted from the latin 'spectaculum', which was used to designate theatrical representation in France. In the case of movie, spectacle was the grand show with showy technological attractions. The spectacle have been to show the political and socio-historical relationships in a society. But in my study, I want to start the premise that the cultural performance planed by the Emperor Gochung in the Daehan Empire has the attribute of 'theater state', which can awaken the certain collective emotion to connect the Emperor and his people in the Daehan Empire period of the Emperor Gochung of the late 1900. In addition to it, I search for the historical collective memories of the Daehan Empire. The government of the Daehan Empire was continuing with its efforts to enforce and recollect the imperial images and authority of the Emperor and his Empire to get the approval of the people and international society. The effect of spectacle consisting of theater state was the concrete effort to establish the collective memories of the Daehan Empire by remodelling and rebuilding the Seoul, the capital of the Empire and performing the national ceremony such as the korean pagent(Gae-Dung거둥) and parade to set the portrait of the Emperor(A-Jin어진), the geo-body of the Empire.

Struggles to gain acknowledgement of identity have a characteristic of movement to recover human dignity. Participants in this movement come to confirm themselves as the subject of rights and communicate one another, free from oppression. Being guaranteed the opportunity to participate in the public opinion formation process is an indispensable element of human rights. In 1980, though it was short and incomplete, Gwangju experienced communal autonomy under the condition that state power was temporarily stopped. The contents and memories of the Gwangju Democratization Movement that intended to protect autonomy of civil society, resisting pillage of state power, remain intact in the 1980 Archives for the May 18th. The 5.18 archives were registered in UNESCO's Memory of the World in 2011, with its value of human rights and protection of democracy being acknowledged. The 5.18 archives have memories of resistance and struggles for justice, and sacrifices and pains of citizens under oppressive political authority in Gwangju, 1980. Thus, these archives are related to the historical struggles for democracy, and suggest a lesson on the transition process towards democracy to us. Preservation and utilization of the documentary heritage constantly lead the memories of historical events to the present, and enable exchanges of experiences and ideas between the present and the future. This study, through the process of UNESCO's Memory of the World registration and post-registration process, beyond the value of archives, tries to examine how historical events are led to the present, through the archives and to discuss the other values of archives.

How is the "Yonsei University Incident" of August 1996 remembered from a periphery perspective and a gender perspective? With this question in mind, I reviewed the history of the revolution and the missing memories in the period from 1996 to 2016 in Korean literature. I tried to recover the story of the revolution experienced and remembered by those who were politically invisible or gender-excluded, by centering on novels with strange reminiscences of the student movement in 1996, namely Yoon I-Hyung's "Big Wolf Blue" ("Big Wolf Blue", 2011), Choi Eun-Young's "Responsibility"(2018), Hwang Jung-Eun's Didi's Umbrella (2019) and Park Sang- Young's "A piece of Rockfish Sashimi The Taste of the Universe"(How to Love in Metropolis, 2019). There is a correlation between the perception of the periphery and the name of the "unrememberable" revolution. And this fact tells us that revolution does not mean the same thing to everyone, even when it "passes" through the midst of a revolution that shares the imagination of a better society and the desire to reorganize the system. In other words, it emphasizes that the logic of exclusion and hierarchy was still in operation even at the moment of revolution. It would be said that this review is not only a rethinking of the student movement, but also a reevaluation from the gender perspective of Korean society in the 1990s.

본 논문에서는 프레임 메모리를 줄이는 간이형 비디오 디코더의 다섯가지 알고리즘을 연구하여 성능을 비교한다. fixed-length ADPCM 기법을 적용하여 메모리를 줄이는 알고리즘과 수평 방향으로 decimation 하는 방법, 그리고 DCT 계수를 filtering 하는 방법을 구현하고 이보다 더 압축률을 높여서 수평 방향으로 decimation 하거나 DCT 계수를 filtering 하는 방법에 ADPCM 기법을 결합한다. 이렇게 함으로써 원래의 비디오 디코더 프레임 메모리의 25% 까지 메모리를 줄일 수가 있다. 메모리 크기를 줄이는 이점 이외에, 하나의 비디오 디코더 구조가 몇가지 압축 모드를 구성하므로 원하는 복잡도와 메모리 크기에 따라 응용이 자유롭다.
