While the importance of barrier-free and fire evacuation design is highlighted in architectural design education, systemic analysis, and examination on such performances are still challenging due to methodological lacks. The present study investigates the effectiveness of BIM-based human behavior simulation for architecture major students' analytical examinations to promote barrier-free and fire evacuation performances. To achieve such an aim, quasi-experiments were conducted, which compare 50 students' analysis and examination scores according to the use and non-use of the simulation, and the data were collected via participants' survey and interview. As a result, T-Test and MANOVA analyses indicate that, compared with its non-use counterpart, the use of human behavior simulation better facilitates the students' (1) examination of the physical properties and dimensions for the disabled's accessibility and evacuation, (2) understanding of the bodily capacity and handicap of the disabled, (3) examination on the spatial layouts and locations of exits, (4) understanding on evacuees' urgent behaviors, and (5) responsibility as an architect. Based on previous studies, the reasons of statistical results are interpreted as the explicit observation and analytical measures of multiple numbers of virtual-evacuees and direct-experience from body range of the disabled responding to the populated occupants as what they face in authentic reality.

This paper interprets the social and cultural significance of the "landscape" in North Korea by exploring the object and context of the text referring to the "landscape" in North Korean literature. To this end, the paper first classified the objects describing "landscapes" in serial publications and newspaper articles by types and grouped them according to trend. As a result, the social and cultural significance of the "landscape" in North Korea can be divided among "Projection Object of Orthodoxy", "Visuality extended to the City" and "Visible Socialist-Fairyland". First, in an article about Baekdusan (Mt. Baekdu), "landscape" was used as a medium to prove the legitimacy of the successor. Next, in the Kim Jong-Un regime, "landscape" was used as a word to describe the visual interactions by human economic activities. Finally, as a way to visualize the achievements in the landscape sector, a term for ranking landscapes such as "Socialist-Fairyland" was adopted during Kim Jong-Un's reign. This can be interpreted as one of the devices visualizing the "landscape" and is clearly distinguished from the past.

In this study, we tried to quantify the actual cross-sectional area inside the bore when scanning by the MRI system with various bore sizes. To this end, a comparative analysis was conducted by both of blueprint of each MRI equipment and actual measurement in the field. As a result of analysis, ACSA(Actual Cross-Sectional Area) in Ingenia CX, Elition X, uMR 780, Omega, Vida, Lumina, Architect, Premier is recorded as 171230, 232150, 242100, 309332, 230760, 230760, 229380 and 235990 ㎟, respectively ACSA% was 60.6, 60.3, 73.0, 70.0, 60.0, 60.0, 59.6, and 61,3%. In addition, DTB (Distance from Table top to Bore top) recorded 400, 407, 445, 495, 405, 405, 405, 403, and 412 mm. Through this study, it was confirmed that there is a difference between the bore size according to each MRI system and the actual cross-sectional area during MRI scanning. Accordingly, if we consider the internal actual area just not bore size at the clinical site, useful diagnostic images can be obtained in the end with better convenience.

Architecture had played a significant role model in philosophy because the construction of building represented doing philosophy. 'Architecture as metaphor' made it possible that doing philosophy was a kind of construction of thinking and western philosopher considered himself as an architect of idea. As a system of system, architectural analogy gave philosophy a chance to insist himself as a theory of theory. So architecture had always been a privileged model of discourse system and also a fundamental metaphor in philosophy. Because of its original meaning, Architecture as techne could be considered as poiesis, that was the special building(making) in western culture. The archi(arche) - structure(techne) was a ideal model and mechanism of philosophy because with this analogy doing philosophy became a kind of building act to make a logical system of idea. This kind of tradition in philosophy, especially metaphysics, made the characteristics of western philosophy 'architectonic' that implied the meaning of the rational, stable, hierarchical and holistic. But this kind of tradition exposed the problem of philosophy that focused on Identity and excluded the others. The logocentrism of western philosophy was also the limitation of architectonic thinking and its reductionism became a grand monologue which only allowed systematic, rational discourse. Its ideological position Inevitably caused the anti-architectural thinking in modern age as a diverse form of new trend of thinking as like postmodernism or deconstruction. Even Deconstructivism, or 'informe', non-representation in architecture depends upon anti-architectural thinking. Relationship between architecture as metaphor and the building of philosophy is problematique issue.

Today, most data is stored in a database (DB). In the DB environment, the users requests the DB to find the data they wants. Similarity Query has predicate that explained by a similarity. However, in the process of processing the similarity query, it is difficult to use an index that can reduce the range of processed records, so the cost of calculating the similarity for all records in the table is high each time. To solve this problem, this paper defines a lightweight similarity function. The lightweight similarity function has lower data filtering accuracy than the similarity function, but consumes less cost than the similarity function. We present a method for reducing similarity query processing cost by using the lightweight similarity function features. Then, Chebyshev distance is presented as a lightweight similarity function to the Euclidean distance function, and the processing cost of a query using the existing similarity function and a query using the lightweight similarity function is compared. And through experiments, it is confirmed that the similarity query processing cost is reduced when Chebyshev distance is applied as a lightweight similarity function for Euclidean similarity.

This study examines the design intent and the construction background of the UNESCO House in Korea planned in the 1950s, with a focus on the initial plans of the House by Kuzosa Architects & Engineers in 1959. To this day, the House has been evaluated as a representative example of an office building in the 1960s, and an early case of introducing curtain walls in Korea. However, only its technical characteristics have been explored with less emphasis on further research data. This study attempts to demonstrate the social and cultural expectations and the demands of the construction of the House by examining the documents produced at the time and the initial plan. This study also highlights the fact that the House was the first project of the architect Pai Ki Hyung to realize high-rise reinforced concrete construction in Seoul's dense center. In the 1950s, the House was planned as a modern building with a complex of various cultural facilities and offices due to the character of activities of the Commission, and the lack of public cultural facilities in Korea. The plan of the Kuzosa Architects & Engineers was selected through a design competition held in 1959. The House was completed in 1967, which took about eight years from planning to completion with design modification in the 1960s. The initial plan submitted before the design modification shows that Pai used the vocabulary and logic of modern architecture and planned the House not as a simple office building but as a complex cultural facility.

This paper tried to examine the implications of the sites of memory and diaspora memory of the life of Jun Itami(Yoo Dong-ryong), a Korean architect in Japan who is interpellated as Zainichi Koreana adopting theoretical and methodological discussions on memory, sites of memory, diaspora, and identity. To this end, the documentary was selected as the subject of analysis. According to the research results, which consists of a total of 48 scenes, is based on the assumption that the sea and Japan and Korea between the sea are the space of memory, and emphasizes that Itami Jun, who had to live as a borderliner and a stranger is disengaged from the borders of nationalities, territories, and countries. In particular, the story of Jun Itami set the sea as a diachronic space(sites of memory) that penetrates the past and present and explores his diaspora identity. The sites of memory of Jun Itami reconstructed in can be said to be a memory space that makes Yoo Dong-ryong more firmly aware of his diaspora identity as a Korean.

Architectural Monuments have to overcome the challenge of time due to physical properties. The fundamental issue must be grounded in an understanding of history and art to overcome this challenge and make themsustainable. Many efforts to preserve the monuments through the 19^th century and at the beginning of the 20^th century to record them in scientific form were successful. To be aware of the meaning of the art and not to be 'barbare' anymore was behind the promotion of these activities. Above all, the 19th-century French architect Viollet-le-Duc contrasted the concept of barbarism with the concept of art and tried to redefine architecture as art. The ritual to escape 'barbare' played an important role in the end. This consciousness was also at work in the propaganda for the preservation of medieval architectural monuments in France, led by intellectuals such as Rodin. Also, the concept of 'barbare' served as an important yardstick whenever the cause of their loss was questioned while important monuments were destroyed in the First World War. From the viewpoint of Germany, Dehio was the pioneer of the preservation movement and documentation of monuments. The principle he advocated was preservation, not restoration. The historian Pevsner, who moved to England, also surveyed monuments in various parts of England and left them in the same format as Dehio. These facts show that architecture as art plays a fundamental role in the history of human life.

In this paper, we proposed VW-FedAVG(Validation based Weighted FedAVG) which updates the global model by weighting according to performance verification from the models of each device participating in the training. The first method is designed to validate each local client model through validation dataset before updating the global model with a server side validation structure. The second is a client-side validation structure, which is designed in such a way that the validation data set is evenly distributed to each client and the global model is after validation. MNIST, CIFAR-10 is used, and the IID, Non-IID distribution for image classification obtained higher accuracy than previous studies.

Since the era of industrial revolution, the waste volume has continued to grow; waste management has thus become one of the major global environmental challenges facing humanities today. Waste treatment and management issues trigger NIMBY movements, and disputes among states, governments, and social actors over the issues have been accelrating. At the level of states and sub-states, various measures including institutions, laws, regulations, market-oriented methods, consensus and collaborative governance have been introduced to address various problems associated with waste. More recently, science and technology has been applied to the waste treatment and management under the notion of circular economy. However, societal support for addressing waste problems still remains inadequate, calling for new approaches and alternative pathways. In this context, this study examines two cases of urban incineration plants designed by Hudertwasser, Austria-born artist and architect: Spittelau, Austria, and Osaka, Japan. Through these case studies, I demonstrate how creative and innovative culture-technology convergence can shed new light on challenging environmental issues such as an urban waste problem.
