This study aimed to interpret aesthetic properties of post-industrial parks with a perspective of the sublime. It examined the roles of the sublime related to landscape architectural history and traced aesthetic characteristics of post-industrial parks based on aesthetic issues of the sublime. In the history of landscape architecture, the sublime had expanded the scope of aesthetic enjoyment. It had operated as an alternative aesthetic category against conventional landscape design. At the same time, it had been associated with the original role of landscape architecture, which created artworks by taming wild and terrible qualities of wilderness or brown field. This study discovered sublime characteristics of post-industrial parks, inquiring into the relationship between the aged industrial infrastructures and wild plants. First, the sense of industrial structure and the sense of plants have conflict dialectically, constructing an aesthetic field of unique sensory experiences. Second, the dialectical relationship produced an uncertainty in time so that people can experience the complexity of time. Third, post-industrial parks proposed an alternative view of nature. Post-industrial parks presented healing power to restore contaminated land through ecological design strategy so that people can find the quality of wilderness in the brown field of urban landscape. As a result, an aesthetic experience of post-industrial parks produced a sublime impression.

The purpose of this study is to provide ideas for the development of bag design by analyzing the expression types and aesthetic formativeness of modern bag design using tassels and fringe given the newtro trend pursuing analog sensitivity in modern society. The methods and scope of this study are as follows. First, the related literature and internet data were reviewed in order to examine the expression types and characteristics of the bags of the West and East. Next, the definition and characteristics of tassel and fringe decoration in terms of the history of clothing were analyzed. Finally, the expression types and aesthetic formativeness of tassels and fringe were derived through the analysis of modern bag design shown in the fashion collections since 2010. The bags decorated with the tassels and fringe bring a variety of visual effects depending on the attachment position, direction and material composition, concentrating the gaze and radiating original style. In this study, the expression of tassels and fringe in modern bag design was classified into three types: surface decoration, shape variability, and object combination. Next, the aesthetic formativeness of modern bag design using tassels and fringe as decorative elements appeared through the mixture of heterogeneous materials and playfulness through imagination, exaggeration through extension of length and volume, and retro characteristics through reinterpretation of tradition. This study is expected to contribute to creative ideas of modern bag design which requires a global sense, which has been used in various cultures for a long time.

As stated in Part(I), the use of the isolator is meant to protect a structure from seismic risk, by concentrating the inelastic deformations to relatively cheap and replaceable devices while the rest of the structures remains elastic. This research has been carried out to investigate the effects of various structural parameters and isolator characteristics on the seismic response of Base Isolated Bridges. Simplified analysis method for practical design is developed by using the results. The Proposed Code-Type approach method can be used to estimate the inertial forces accurately, not only at the isolator but throughout the height of the Base-Isolated Bridges. The proposed method is recommended to use in preliminary design tool or even a final design tool for Base Isolated Bridges. For the validation of simplified design method, examples with artificial earthquake time history and design response spectrum for P.C Box Bridge with bilinear hysteretic steel damper are evaluated.

The purpose of this study is to analyze Bakst's stage costume illustrations for Ballets Russes. The Russian Ballets has renown in the West since the early 20th century. Diaghilev first made his name as the organizer of art exhibitions in Russia and Western Europe. Diaghilev risked presenting only ballets in 1909, that time Bakst designed $Sch{\acute{e}}h{\acute{e}}razade$, L'Oiseau de Feu and Le Carnival. $Sch{\acute{e}}h{\acute{e}}razade$ was something new which overwhelmed the French people by then. It was seen to be the achievement of Wagner's idea where all the elements; the music, the design, the choreography, and the dancing fused into a perfect whole. The entire production was a hitherto unseen harmony of colors, sounds and movements. For the 1911 season in Paris, Diaghilev planned to present six new ballets and Bakst designed four ballets. Bakst's design of the set and the costume greatly shocked the audience. His "Originality" shines on the fact that he introduced a palette of colors in theater for the first time in history. He used a magic of colors to suggest the secret meaning of what was happening on the stage. The results can be divided into three distinct characteristics. First, oriental designs such as $Cl{\acute{e}}op{\hat{a}}tre$, $Sch{\acute{e}}h{\acute{e}}razade$, L'Oiseau de Feu, La $P{\acute{e}}ri$ and Le Dieu Blue with Russian, Indian and Persian traditional design in headdress and accessories ars found. Second, Le Carnival and La Spectre de la Rose used romantic styles with oriental details. Third, Greek chiton and Himation are used in Narcisse, $H{\acute{e}}l{\grave{e}}ne$ de Sparte, $L'Apr{\grave{e}}s-Midi\;d^{\grave{\;}}un$ Faune and Daphnis et $Chlo{\acute{e}}$ inspirde with various colors and geometic patterns. Bakst's orient of lush colored costumes, head dress, cushions, rugs and hangings became the immediate fashion imitated by Parisian couture houses and interior decorators.

This is a study on the origin of fashion imaging. First of all, 1 looked into the history of French fashion printmaking from late 16th century to early 19th century. Then studied the changes in the characteristics of context and form over the different periods and summarized each concept. At the same time, I looked into the process of fashion magazine evolving from fashion printmaking. In order to find out how fashion printmaking dealt with the characteristics of fashion media, 1 researched the commercial environment of fashion printmaking and reorganized the methodology of its media's role. Such analysis and results helped to reach a definition on how to regulate fashion printmaking. Fashion imaging was sparked by a small curiosity. As people began to be rage over new things, it came to introduce the fashion leaders of the public combined with the attributes of trend. At times when changes were so big that they were unpredictable, it itself became a fashion leader. Then a fashion creator emerges and it's function changes to that of a communication media. Moreover, the regular issuance of fashion printmaking implemented the concept of trend cycle and fashion imaging completely fulfilled the conditions of a communication media. The massive increase in the production of fashion printmaking and magazine contributed to the spread of fashion and the diffusion of printmaking lead to mutual complementation and synergy necessitated by fashion. Thus, the democratization of fashion and the commercialization of printmaking art occurred at the same time.

Newmark-type deformation analysis has rarely been done in Korea due to the popularity of simple pseudo-static limit equilibrium analysis and detailed time-history FE/FD dynamic analysis. However, the Korean seismic dam design code updated in 2011 prescribes Newmark-type deformation analysis as a major dynamic analysis method for the seismic evaluation of fill dams. In addition, a design PGA for dynamic analysis is significantly increased in the code. This paper aims to study the seismic evaluation of four existing large fill dams through advanced FEM/Newmark-type deformation analyses for the artificial earthquake time histories with the design PGA of 0.22g. Dynamic soil properties obtained from in-situ geo-physical surveys are applied as input parameters. For the FEM/Newmark analyses, sensitivity analyses are performed to study the effects of input PGA and $G_{max}$ of shell zone on the Newmark deformation. As a result, in terms of deformation, four fill dams are proved to be reasonably safe under the PGA of 0.22g with yield coefficients of 0.136 to 0.187, which are highly resistant for extreme events. Sensitivity analysis as a function of PGA shows that $PGA_{30cm}$ (a limiting PGA to cause the 30 cm of Newmark permanent displacement on the critical slip surface) is a good indicator for seismic safety check. CFRD shows a higher seismic resistance than ECRD. Another sensitivity analysis shows that $G_{max}$ per depth does not significantly affect the site response characteristics, however lower $G_{max}$ profile causes larger Newmark deformation. Through this study, it is proved that the amplification of ground motion within the sliding mass and the location of critical slip surface are the dominant factors governing permanent displacements.

Because offshore structures are affected by various environmental loads, the risk of damage is high. As a result of ever-changing ocean environmental loads, damage to offshore structures is expected to differ from year to year. However, in previous studies, it was assumed that a relatively short period of load acts repeatedly during the design life of a structure. In this study, the residual life of an offshore wind turbine support structure was evaluated in consideration of the timing uncertainty of the ocean environmental load. Sampling points for the wind velocity, wave height, and wave period were generated using a central composites design, and a transfer function was constructed from the numerical analysis results. A simulation was performed using the joint probability model of ocean environmental loads. The stress time history was calculated by entering the load samples generated by the simulation into the transfer function. The damage to the structure was calculated using the rain-flow counting method, Goodman equation, Miner's rule, and S-N curve. The results confirmed that the wind speed generated at a specific time could not represent the wind speed that could occur during the design life of the structure.

A human face figure is a visual symbol of identity. Each different face per person is a critical information differentiating each person from others and it directly relates to individual identity. When we look back human history, historical change of recognition for a face led to the change of expression and communication media and it in turn caused many changes in expressing a face. However, there has not been no time period when people pay attention to a face more than this time. Technically, the advent of computer graphics opened new turning point in expressing human face figure. Especially, a visual image which can be produced, saved, and transferred in digital has no limitation in time and space, and its importance in communication is getting higher and higher. Among those visual image information, a face image in digital is getting more applications. Therefore, 3d (3-dimensional) expression of a face using computer graphics can be easily produced without any professional techniques, just like assembling puzzle parts composed of the shape of each part ands texture map, etc. This study presents a method with which a general visual designer can effectively express 3d type face by studying each producing step of 3d face expression and by visualizing case study based on the above-mentioned study result.

The purpose of this study is to suggest guidelines for riser fatigue analysis in terms of selection of reasonable analysis method. Three analysis methods (spectral, regular wave, rain-flow counting) are introduced and compared. As the riser systems give non-linear response, the time-domain analysis method is more preferred than frequency-domain analysis method. The spectral fatigue analysis method, however, is still useful for identifying fatigue prone areas. Once stress RAO is established, fatigue damage can be calculated very quickly. The regular wave method and the rain-flow counting method are more time consuming but give more exact results compare to spectral method. In case of regular wave method, a set of regular waves which represent random sea states is considered for dynamic analysis. The rain-flow counting method is the most intuitive and exact method because it refers time history stresses containing most of non-linear effects of the riser system. However, it is not common for early design stage to use rain-flow counting method because of its high cost. In this study, it was confirmed that the regular wave method is the most cost effective way in specific cases. However, if the system is highly non-linear, it seems that the regular wave method gives less accurate results than rain-flow counting method. Therefore, it is imperative that the engineers select appropriate analysis method based on design stage and given engineering period. This paper also discusses the theoretical background of each calculation method and hydrodynamic aspects of marine riser systems. A steel catenary riser (SCR) line on FPSO was considered and marine dynamic program (OrcaFlex) was used for static and dynamic analysis.
