This paper deals with preservation and restoration as a universal approach to conserve architectural heritage. The questions on how to preserve or restore them have been always major issues for many old buildings. Reading changes in ways of the thinking to solve such matters in the past helps to grasp the fundamental concepts to conserve cultural heritage at this point in time. The method is an important stage that leads to change our current attitude. Both the ways of the thinking for preservation and restoration should be re-interpreted to preserve memory or to restore identity depending on the current situation, and even should no longer be understood as two opposite options. Therefore, this paper focuses on the epistemological notion and reveals the origin and premise of modern historical perception that has become disconnected from the past works. By taking the writings of $Eug{\grave{e}}ne$-Emmanuel Viollet le Duc, John Ruskin, and Camillo Boito into consideration, the thesis shows that their thought, in the common denominator of the time, is a kind of reflection of consciousness according to particular historical contexts and that their ideas echo three dialectical paradigms derived from past and present, memory and forgetfulness, and history and truth.

The purpose of this study is to reveal the meaning of Le Corbusier's works focused on Maison Guiette. This House was completed in 1926, 4 year later than the work of the Citrohan and also, this house is the only remaining mixed use Dwelling in Belgium. It offers a fine example of the early architectural concepts of Le Corbusier's. Despite these important facts, the meanings of the ideas of this house have not been paid attention as much as other houses constructed at the same period, such as Maison La Roche, Maison Stein de Monzie, Villa Savoye, etc. In his book, 'Oeuvre Complete 1910-1929', Le Corbusier mentioned as follows: "A special solution imposed by Belgian housing developments characterized by a dimension of 6 meters of frontage and a very great depth. The staircase serving the various floors is like the ladder of Jacob climbs Charlie Chaplin in the "Kid" and This house is an architectural experiments of his ideas. And this study aims at analysing the relationship between Maison Guiette and spaces on the basic of Le Corbusier's 'Five Points of a New Architecture' which had a great effects on architectural history and became a fundamental elements for the change into the Modern housing. By analysing the points in regard with the Features of Architectural Concept Applied in Maison Guiette, The Five Points are the background of the interpenetration of the interior and the exterior. To attain this, this research appraises each points in detail in regards with Maison Guiette. The study of Maison Guiette will be an important architectural subject to clarify the meaning of his later works and ideas.

The purpose of this paper is to study the meaning of Rem Koolhaas's works focused on Villa Dall'Ava. This House which offers a fine example of the early architectural concepts of Rem Koolhaas was completed in 1991, 7 year earlier than the Maison Bordeaux and also this work is the only one house constructed in Paris. Rem Koolhaas, one of the most influential architects representing contemporary architecture in these days is interpreted so diversely as new constructivism, deconstruction and new scientism etc. The relationship between Modernism architecture and the architecture of Rem Koolhaas is supposed in various point of view in recent studies. Although the leading background on which the architectural inclination of Rem Koolhaas is de-constructivism, various interviews, editorials and other perspectives give clue that Rem Koolhaas was influenced by Modernism. His architectural concept is connected with the architectural principles of Le Corbusier: 'Five Points of a New Architecture' and 'Dom-ino system', which are especially applied a lot to Villa Dall'Ava in the modified form. This study is to research the architectural characteristics of Villa Dall'Ava by analyzing the layout, plan, elevation, section and structure, which revealed the architectural connectivity between the concept of Rem Koolhaas and the architectural principles of Le Corbusier which had a great effects on architectural history and became a fundamental elements for the change into the modern architecture. In practice, the architectural work of Rem Koolhaas remind the architectural principles of Le Corbusier. This research appraises each points of 'Five Points of a New Architecture' in regarding with Villa Dall'Ava whose study will be important to find the meaning of the works and ideas of Rem Koolhaas.

In this study, the royal protocols of the Joseon Dynasty, known as uigwes, were reviewed to clarify the materials and structure of Korean traditional walls. For this, the Yeonggeon-and Sanreng-uigwes were thoroughly reviewed, and then the names, materials, and construction methods of the traditional walls were systematically organized. In addition, mix proportions of plastering materials used in the walls were estimated based on the records in the uigwes; these were compared with the ratios specified in the current specifications. As a result of the comprehensive review, it was found that the mix proportions of the plastering materials varied depending on importance of buildings, type of walls, and the raw materials. Based on this, it was concluded that the characteristics of each uigwe should be considered when studying the mix proportion of materials for the traditional walls. It was also found that there were differences between the traditional and modern specifications for the wall constructions. That is, historical records and the specifications currently used were different in terms of constituent materials, construction methods and mix proportions. As a cause of the difference, the disconnection of the traditional methods and the introduction of foreign plastering techniques during the rapid social change in the 20th century were suggested.

Modern agriculture is changing from resource-oriented agriculture to technology-oriented agriculture. Agriculture, which combines science and technology, is recognized as a new growth engine, and governments, local governments, research institutes, and industry are working together to develop and disseminate various devices necessary for smart farms to build intelligent smart farms. Recently, research is being conducted to build a more intelligent agricultural environment by building a cloud platform. In this paper, we propose a plan to build an urban energy - independent smart farm that can utilize leisure time and agricultural activities by utilizing the rooftop of a city. Also, by using IT technology, various data of smart farm can be managed on remote server, and HMI module for controlling internal environment of smart farm can be developed to manage smart farm automatically or semi-automatically. The service model suggests a model that can manage the internal environment of the smart farm based on mobile.

The cross-flow turbine is one of the most famous and widely used hydraulic power systems for a long time. The cross-flow turbine is especially popular in many countries and remote regions where off-grided because of its many benefits such as low cost, high efficiency at low head, simple structure, and easy maintenance. However, most modern turbines, including the cross-flow turbine, are unsuitable for the ultra-low head situation, known as less than 3m water head or zero head with over 0.5m/s flow velocity. In this study, we demonstrated a 20kW class inverted-type cross-flow turbine's performance. First, we reevaluated our previous studies and introduced how to design the inverted-type cross-flow turbine. Secondly, we fabricated the 20kW class inverted-type cross-flow turbine for the performance test. And then, we designed a testbed and installed the turbine system in the demonstration facility. In the end, we compare the demonstration with its previous CFD results. The comparing result shows that both CFD and real model fitted on guide vane angle at 10 degrees. At the demonstration, we achieved 42% turbine efficiency at runner speed 125 RPM.

With the advent of the ubiquitous era due to the development of science and technology in the modern society, interest in data generated in the IoT environment has increased socially. However, the existing IoT platform has difficulties in processing inquiry requests that require large amounts of throughput, such as statistical processing of large amounts of data. Accordingly, in this paper, we propose an IoT platform that can flexibly accommodate requirements for inquiry requests and improve inquiry performance. The platform proposed in this paper showed a performance improvement of about 1200 times in terms of average response time by introducing a separate read database. By separating the object model into a command side and a query side, the complexity of the object is reduced to meet the various demands on the platform. It was made to allow quick acceptance of the matter.

In actual battlefield environment, the naval ships which have specific missions have to respond to the attack of hostile forces. Especially, in modern warfare, the importance of the survivability of naval ships are increasing due to the high lethality of armaments. Naval ship survivability is generally considered to encompass three constituents, susceptibility, vulnerability and recoverability. Recently, among these three constituents, many researches on vulnerability have been conducted. However, for the vulnerability of naval ships, most of researches are aimed towards the detailed design stages where implementing changes is heavily constrained or even impractical. In this paper, vulnerability assessment model for naval ships on a theater engagement is developed by using M&S technique. By using this model, the characteristics of platform and armaments are reflected on the damage of naval ship. The basic logic of damage assessment is also considered in detail. The damage status of the naval ship is quantified by defining a representative state index of onboard equipment for each system.

The purpose of this study is to expand satirical expressions that appear in a wide range of arts into fashion and to analyse and present satirical expressions that appear in contemporary fashion through the collections of Thom Browne. Theoretical examination of satirical concepts were made of domestic and foreign academic theses, dissertations, precious studies, and publications related to satire. Analysis was conducted on cases in which satirical expressions were applied in literature, painting, sculpture, and fashion. Based on these studies, analysis was conducted on satirical expressions appearing in Thom Browne's work. Material was gathered from collection reviews, interview articles, professional books, and internet photo material from professional fashion magazines encompassing 16 years of Thom Browne's collections officially recorded in the international fashion magazine 'Vogue', ranging from the 2006 S/S collection to the 2021 S/S collection. From this, a total of 1,753 photos were collected as data. Characteristics of satirical expression were analyzed and the results were as follows. A fluid reconstruction of 'gender fluid', dual meanings of metaphorical allegories, playful expressions of visual wit, constructions made of overlapped disassembled material, and borrowing of morphological distortion were all identified. Accordingly, satirical approaches as social aspects and objects in the flow of modern thought appear as positive forms based in humor that hope to be improved. This study anticipate the concept of satire will expand into a positive form as a new direction of fashion.
