A discourse on the Independence Hall of Korea, a representative cultural project of the 1980s, has been understood as a repetition of the traditional debate of the 1960s. It was considered as a petrified propaganda aimed at ensuring the fragile legitimacy of the military regime, and the architect as a sympathizer. Even if all these facts are true, it does not give any explanation for the architecture. Scrutinizing the building process and the change of discourse in the Independence Hall of Korea, this paper tries to explore a section of contemporary Korean architecture in the 1980s. The architect who designed the Independence Hall of Korea is Kim Kiwoong, however, it was Kim Won who took charge of overall scheme for it. Kim Won replaced the role of a technocrat in the 1960s, who deprived architects of his autonomy. Against this backdrop, Kim Kiwoong attempted to explain his own building via various concept like postmodernism, which gave him very proper context. But, later, he appropriated words like void and madang. These derived from some architectural historian's researches in 1970s, and were to predict the architecture of the 1990s.

The Olin Library in St. Louis was an important design competition for the United States in the 1950's, the rear of America's modern architecture. The participants of this competition were a variety of representative architects and groups of its time. With the library's functional rationality, the Olin Library competition was legible of the aspects of modern architectural flow. The competition required two demands. The first demand was absolute importance in character definition of place, which was to satisfy the site conditions approached from campus design. Secondly was related to interpretation of morphological symbolism in an architectural matter. The experiments of American modern architecture started to change its ideal goal gradually ; accommodating the altering public's code, at the same time, maintaining the original modern value was the reason to changing the ideal goal. As a turning point, the Olin Library should be understood as an important work, which divulged the value change of architectural interpretation.

Finite element methods have often been used for structural analyses of various mechanical problems. When finite element analyses are utilized to resolve mechanical systems, numerical uncertainties in the initial data such as structural parameters and loading conditions may result in uncertainties in the structural responses. Therefore the initial data have to be as accurate as possible in order to obtain reliable structural analysis results. The typical finite element method may not properly represent discrete systems when using uncertain data, since all input data of material properties and applied loads are defined by nominal values. An interval finite element analysis, which uses the interval arithmetic as introduced by Moore (1966) is proposed as a non-stochastic method in this study and serves a new numerical tool for evaluating the uncertainties of the initial data in structural analyses. According to this method, the element stiffness matrix includes interval terms of the lower and upper bounds of the structural parameters, and interval change functions are devised. Numerical uncertainties in the initial data are described as a tolerance error and tree graphs of uncertain data are constructed by numerical uncertainty combinations of each parameter. The structural responses calculated by all uncertainty cases can be easily estimated so that structural safety can be included in the design. Numerical applications of truss and frame structures demonstrate the efficiency of the present method with respect to numerical analyses of structural uncertainties.

This study conducted a subjective evaluation of brightness perception and visual discomfort according to dimming speeds and CCTs(Correlated Color Temperatures). Dimming speeds of two different CCT lights(2,700K, 6400K) were set to 1.7%/s, 3.3%/s, 5.0%/s, 6.7%/s, and 10.0%/s respectively. Subjects checked the time when they perceived the change of the brightness and visual discomfort. As a result, when dimming speeds were 1.7%/s, 3.3%/s, 5.0%/s, 6.7%/s, more than half of subjects responded the change of the brightness in 55.0~45.0% dimming ratios, and felt the visual discomfort in 35~25% dimming ratios. When the brightness was changed, dimming level responded to the brightness perception of hight CCT(6,400K) was higher about 8.0% then dimming level responded to the brightness perception of low CCT(2,700K). Dimming level responded to the visual discomfort of low CCT(2,700K) was higher about 5.0% then dimming level responded to the visual discomfort of hight CCT(6,400K).

In high school classrooms, it is reported that ventilation is often insufficient, increasing health risks among students. Therefore, indoor air quality in school classrooms is very important in terms of students' health and learning abilities. In this study, the effect of window opening, which is a control mechanism for air control in summer high school classrooms, on the change in air and indoor environment of the classroom was analyzed and physical conditions of indoor and air environment were observed during the classroom course, and satisfaction of the students and teachers was assessed with questionnaires. It was found that change rate of $CO_2$ concentration in classroom was effectively reduced by carrying out activity of opening the window by active environment control activity of occupants at break time, intermission time and cleaning time. And optimal window opening by students was presented to prevent unpleasantness and degradation of indoor air quality and the effects were analyzed.

In this study, the effect of window opening, which is a control mechanism for air control in winter high school classrooms, on the change in air and indoor environment of the classroom was analyzed and physical conditions of indoor and air environment were observed during the classroom course, and satisfaction of the students and teachers was assessed with questionnaires. And the changes in air environment were assessed by the performance of the duster cleaning work in the classroom. It was found that 84.6% of the students surveyed said the air was stuffy. And among the alternatives, opening windows all times during class was most effective in reducing CO₂ concentration and PM concentration was measured within classroom's standard. In addition, the concentration change rate of duster cleaning work was reduced by 74.4% and 65.4% of PM10 compared to broom cleaning work.

The study used the whole-life carbon assessment method to conduct a thorough carbon-neutral evaluation of a standard steel structure. To further assess carbon emissions, 11 design-changed models were evaluated, with changes made to the span between beams and columns. The results of the carbon emission assessment showed savings of approximately 13.1% by implementing the stage of the beyond life cycle. Additionally, the evaluation of carbon emissions through design changes revealed a difference of up to 42.2%. These findings confirmed that recycling and structural design changes can significantly reduce carbon emissions by up to 48.6%, making it an effective means of achieving carbon neutrality. It is therefore necessary to apply the stage of beyond life cycle and structural change to reduce carbon emissions.

It is a common situation to limit entrance to the multi-use buildings for efficient control and prevention of the spread of COVID-19. This study chiefly aims to find out efficient methods to establish evacuation plans when temporary changes of the building circulation system occurs. If architectural design were done with the pre-consideration for the changes of building circulation systems, through the analysis of multi-use buildings, it is expected to we can prevent the spread of disasters when they happen. This study is geared to establish efficient evacuation plan for the temporary circulation plan when disaster happen, through the analysis of multi-use buildings for architectural planning as well as the human behavioral patterns.

The 1960s is a transitional era in the history of architecture. The Byker housing redevelopment project well reflects this situation, and is a good example of materialization of social pluralism and expressional needs of a community. Therefore it was investigated in order to see its meanings in the history of mass housing in the Western countries. The conclusions are as follows: It is the first large-scale project where the concept of user participation was sucessfully realized; It suggested various tools of desirable design methodology; It made a paradigmatic change from modernism to post-modernism in the history of contemporary mass housing projects.

This thesis is to research the change in attitude regarding the architectura ornament. One of the key dogmas within Modern Movement of art and design was anti-ornamentalism. The modernist had revolted against ornament and believed that the greatness of the modern age might lay in its inability to produce a new form of ornament. Architectural ornament has been passed through an process of evolution in a decadent stage. In this context, the purpose of this study is to identify historical meaning of architectural ornament in the age of transition toward Modernism.
