  • Existing pedestrian and evacuation models generally seek to find locally optimal solutions for the shortest or the least time paths to exits from individual locations considering pedestrian's characteristics (eg. speed, direction, sex, age, weight and size). These models are not designed to produce globally optimal solutions that reduce the total evacuation time of the entire pedestrians in a building when all of them evacuate at the same time. In this study, we suggest a globally optimal model for indoor pedestrian evacuation to minimize the total evacuation time of occupants in a building considering different distributions of them. We used the genetic algorithm, one of meta-heuristic techniques because minimizing the total evacuation time can not be easily solved by polynomial expressions. We found near-optimal evacuation path and time by expressing varying pedestrians distributions using chromosomes and repeatedly filtering solutions. In order to express and experiment our suggested algorithm, we used CA(cellular automata)-based simulator and applied to different indoor distributions and presented the results.

  • This study proposes that Malevich's 1913 performance "Victory Over the Sun" was not just Cubo Futurism, but that it produced Suprematism in the early 20th century. "Victory Over the Sun" did away with traditional set and costume design and a call to the Russian avant garde. Therefore, this study analyzes the characteristics of set and the costume design in "Victory Over the Sun", and considers how it impacted twenty-first century fashion designers like Margiela. The results of the study are as follows: first, Margiela reinterpreted the characteristics of the costumes featured on "Victory Over the Sun" from a cubist perspective and represented geometric spatial structures and mechanical human images through changes in methods and materials. second, he designed costumes by applying to the set and costumes expressed black & white images on "Victory Over the Sun". and third, Margiela reinterpreted the warrior image using geometric forms and colors in a creative way. Contemporary fashion designers, including Margiela, express their artistic creativity through various representational and materials choices. They want to convey their subjective personality and emotional sensibility to the public by mixing and deforming existing arts like painting, sculpture, and crafts to create new images. Thus, the creative intentions of the latest fashion designers have expanded art of costume design, exemplifying the process by which art is evolves and is made new.

  • Temporal and spatial comparisons of acid mine drainage contaminated waters are difficult because of the complex physico-chemical nature of the pollutant. In the present study, an acid mine drainage index has been developed and evaluated for the assessment of surface waters. AMD index is calculated using a modified arithmetic weighted index using seven parameters which are most indicative of AMD contamination, i. e. pH value, sulphate, iron, zinc, aluminum, copper and manganese. Weighting is used to express the relative indicator value of each parameter. The proposed AMD index is used to quantify contamination from acid mine drainage over ten different old mine sites and assess the degree of impact on surface on surface waters. As a result of AMD evaluation, the Sukbong Mine located near the Moonkyung province showed lowest AMD value indicating the worst acid mine drainage quality. In overall, Youngdong mine sites showed higher contaimination compared to the other mine sites including Youngsuh, Choongbu, Suhbu and Nambu area.

  • In the late 1970s, the method of quantitative and scientific space structural analysis based on graph theory was introduced to the process of space design, which arranges design and functional elements, as relying heavily on intuition could produce errors due to unverified experiences and prejudices of the designer. As the method of space analysis is complex and hard to express visually and requires repetitive operations, it was discussed theoretically only. However, with the development of computer performance and graphic in recent years, visualization became possible. But the method of visual structural analysis of space is at the level of two dimensions and it is not easy to get accurate data when it is applied to limited three dimensional space such as an interior space. For the visual structural analysis of space, this study presents 4 indices including visibility volume level, pure visibility connection frequency, effective visibility connection frequency, and path visibility connection frequency. This study also presents space division using three dimensional arrangement rather than the existing vector operation method and raytracing algorithm at the lattice constant. Based on this, an analysis tool for the visible regions of three dimensional space that is capable of evaluating at multiple points by using three dimensional game engine and presentation tool that allows the analyzer to interpret the data effectively is made. It is applied to 2 prototype models by displacing Z axis, and the results are compared with UCL Depthmap to verify the validity of data and evaluate its usefulness as a multidimensional, multi-view space analysis tool.

  • The purpose of this study is the analyze the spatial structure and housing component of the prairie style house of Frank Lloyd Wright during the Prairie Era which is between 1893-1910. The research results can be summarized as follows 1) In spite of European style influences which were fashionable at the time, Wright tried to attempt altering the space and form of his works (houses) from his unique architectural style. 2) All solid walls which are usually inside the square prairie and the cross floor plans were removed for interaction between the outside and inside spaces in a house creating an organic space. So the inside space of the house feels wider than the original space because of the available natural light. 3) Frank Lloyd Wright's early works were similar to the homes built at that time. However, as time passed, he remembered and was influenced by the Frobel's educational system blocks he played with as a child as well as the surrounding Midwestern USA prairies where he grew up. 4) The early prairie floor plan was square divided into nine equal parts which is classic floor planning. Wright, however, created his new unique architectural style. His style has developed into the prairie style and various floor plans. 5) Wright introduced a 3-dimensional architectural form of composition (cantilever, long eaves, etc.) to express symmetry and horizontal lines of the house. 6) Rather than emphasizing vertical lines in his works, Wright began emphasizing more horizontal lines like the horizontal lines of the actual prairies. This meant the surrounding environment of a house is always in nature.

  • In 16th century, during renaissance time, Britain's queen Elizabeth I, as a means to express her authority, had an exaggerated clothing styles and was the fashion leader of the time. Thus, through a media of Cinema, tried to find out the characteristics and different aspects of the history of clothing styles, of how they changed, ascertained, restored, and reappeared in the modern time. The research was based on the consideration of Elizabeth I's 33 portraits and her clothing styles; and the research is also from analysing the movies from 1937 to 2007, a total of 9 Cinema and 102 clothes. Movie costumes' most important mission is representing the cinema's timely and spatial background. Thus, it is inevitable that ascertaining and restoring Elizabeth I's portrait should be done. However, the movie costume has to show her dramatic lifestyle, dignity, absolute authority, and other visual images. In addition, the costume has to contribute in making artistic effect and thus the creativity of a designer to satisfy all these needs should be added. Based on the findings from the research, the characteristics of Elizabeth I's Cinema costume are first, ascertaining and restoring portraits, second, mixture of silhouette and detail depending on time period, third, partial change on clothing style design, fourth, emphasis of ruff collar, fifth, magnification colors, sixth, avoiding excessive swelling and decoration, and applying modern style on Protective costume. Thus, based on the research, creative design in Cinema clothing, plays an important part in the history of clothing design. I hope this research could work as a foundation reference for clothing design's history.

  • Terrain modelling is composed of a method using the rectangular grid and another using the triangulated irregular network. The method using the triangulated irregular network is most widely used because it can express the characteristics of the terrain well with only a small amount of information on the terrain and also reduces the rendering time. The process of extracting the surface-specific point and a triangular process is needed to construct such triangulated irregular network. This paper concentrates on the process of extracting the surface-specific point. The 8-direction neighborhood method and other transformed methods of the former method are frequently used to extract the surface-specific point. Another method which eliminates the unnecessary points using the Polygon reduction method is also suggested However, the 8-direction neighborhood method has a big fault of also drawing out some unnecessary points. To resolve such problem, we suggest a method of extracting the surface-specific point using the cross section of the terrain. This method reduces the time to extract the surface-specific point and enables a more precise extraction with less terrain information.

  • Even though the importance of emotional aspects in design has been discussed and researched actively, researches mainly focusing on the emotional aspects expressed through architectural materials have been rare. Thus, Previous researches were investigated to draw typical categories to express emotional characteristics through architectural materiality. Case study shows Zumthor's practical methodologies in these state: tectonic expression with creative tectonic methods and local residents' voluntary-participation in construction; enhancement of intimate emotional ties with the local heritage through the usage of local materials and traditional construction techniques; coexistence of past and present materials, and showing the change of materiality via weathering; activation of synesthesia by touching multiple senses; sustainability by using environment friendly materials and construction methods. The results can be hopefully helpful to future researches related to emotional aspects on spatial design.

  • The New Look, which Christian Dior presented in 1947, has been a source of inspiration for contemporary fashion designers, as well as designers for the House of Dior, and has a great influence on them. The purpose of this study is to compare and analyze the aesthetic characteristics of Christian Dior's New Look and the New Look that Christian Dior House designers reinterpreted. The subject and the scope of this study were limited to Christian Dior and the New Look designed by Gianfranco $Ferr\acute{e}$, John Galliano, and Raf Simons who are regarded as worthy successors. The research method was a literature review on previous studies on Christian Dior and related literatures to examine the history of the House of Dior and the aesthetic characteristics of the New Look presented by Christian Dior. Then, an empirical study was conducted through the analysis of collection photographs from 1989 to 2016 that were gathered from the Mode et Mode and Hi Fashion, and websites (British Vogue, Firstview). The results of the study were as follows. First, the aesthetic characteristics of Christian Dior's New Look in 1947 used femininity to express an elegant and beautiful woman, structural property to render the contours of a woman's body, and innovation that changed the formal and gloomy social atmosphere in the post-war years. Second, the aesthetic characteristics of the New Look by Christian Dior were compared with those of the New Look made by designers for the House of Dior. The elegant femininity of Dior can be seen as gorgeous femininity, and sensual femininity, minimalistic femininity, structurality is represented by the spatial structurality of Dior and $Ferr\acute{e}$, the organic structure of Galliano, and the orthodox structure of Simons. Moreover, Dior's retro innovativeness appeared to be $Ferr\acute{e}^{\prime}s$ androgyny innovation, Galliano's deconstructive innovation, and Simons' romantic futuristic innovation.

  • Purpose of this study is to investigate the correlation between Sung-Jung' concept of Sasang Constitutional Medicine and Brain. So, After studying the meaning of Sung-Jung' concept of Sasang Constitutional Medicine, I made a comparative study through the structure, function, development of Brain. The conclusions were as follows. 1. Human's brain acts a rational, control his actions. and It manage human body's physiology and pathology. and It perceive his surroundings, express his emotion through comprehension, synthesis, judgement about information from various fields. and It's abnormality bring about a spiritual, bodily injury. Therefore, human's brain have many correlation with Sung-Jung' concept of Sasang Constitutional Medicine. 2. Neocortex' function have many correlation with Sung' concept of Hearing-Sight-Smell-Taste (聽視嗅味=sensation=a highly mental capacity) through Ear-Eye-Nose-Mouse(耳目鼻?). 3. Limbic-system'function have many correlation with Jung' concept of Sorrow-Anger-Pleasure-Joy(哀怒喜榮=emotion) through Lung-Spleen-Liver-Kidney(肺脾肝腎) 4. Brain-stem' function have many correlation with vitalistic concept through Qui of Sorrow - Anger - Pleasure - Joy(哀怒喜樂之氣)' rise and fall. 5. Relation of emotions and diseases through Limbic system and Autonomic nervous system have many correlation with relation of Sung-Jung and diseases of Sasang Constitutional Medicine 6. Left-hemisphere' function that has superior power of verbal, analysis, logicality, consideration have many correlation with tendency of Soeumin and Taeumin. and Right-hemisphere' function that has superior power of emotion, non-verbal, imagination, spatial perception have many correlation with tendency of Soyangin and Taeyangin.
