As non-verbal communication medium, clothing has various form to express the artist's statement, for example, flattened clothing. On this thesis, three flattened clothing are analyzed, these works convey the meanings, 1) tradition/ contemporary 2) cynical attitude about body 9) new concept to wear

The aim of this study is to examine the characteristics of facade expression designed by Kim. Han-sup, a key architect in the regional modern architecture movement in Gwang-ju and Jeonnam from the 1950's to 1960's. The study begins with the architectural background and thoughts of Kim. Han-sup through literature reviews and introduces an interview with Han. chong-un, a former college student and employee of Kim, which explains the aesthetic architecture that appeared in his design of facades that was reasonably applied to materials, technology, structure and function in line with the economically tough period in Korea. Furthermore, in order to investigate the characteristics of his facade expression, detailed analysis items will be derived from precedent studies. This study will attempt to conclude with statements that his aesthetic architecture can be defined as an emphasis on formative mass by contrasting between basic rectangular forms, implementation with detailed three-dimensional facade by extruding differently vertical and horizontal structural lines and with the pursuit of decoration through compartmental faces on his 12 representative architectural works.

The hindered diffusion in confined spaces is an important phenomenon to understand in a micro-scale the filtration mechanism determined by the particle motion in membrane pores. Compared to the case of spherical colloids, both the theoretical investigations and the experiments on the hindered diffusion of polyelectrolytes is actually more difficult, due to lots of relevant parameters resulting from the complicated conformational properties of the polyelectrolyte chain. We have successfully performed the Brownian dynamics simulations upon a single polyeiectrolyte confined in a slit-like pore, where a coarse-grained bead-spring model incorporated with Debye-Huckel interaction is properly adopted. For the given sizes of both the polyelectrolyte and the pore width, the hindered diffusion coefficient decreases as the solution ionic concentration decreases. It is evident that a charge effect of the pore wall enhances the hindered diffusion of polyelectrolyte. Simulation results allow us to make sense of the diffusive transport through the micro-pore, which is restricted by the influences of the steric hindrance of polyelectrolytes as well as the electrostatic repulsion between the polyelectrolytes and pore wall.

The purpose of this study is to analyze the impacts of three-dimensional land cover on changing urban air temperatures and to explore some strategies of urban landscaping towards mitigation of heat build-up. This study located study spaces within a diameter of 300m around 24 Automatic Weather Stations(AWS) in Seoul, and collected data of diverse variables which could affect summer energy budgets and air temperatures. The study also selected reflecting study objectives 6 smaller-scale spaces with a diameter of 30m in Chuncheon, and measured summer air temperatures and three-dimensional land cover to compare their relationships with results from Seoul's AWS. Linear regression models derived from data of Seoul's AWS revealed that vegetation volume, greenspace area, building volume, building area, population density, and pavement area contributed to a statistically significant change in summer air temperatures. Of these variables, vegetation and building volume indicated the highest accountability for total variability of changes in the air temperatures. Multiple regression models derived from combinations of the significant variables also showed that both vegetation and building volume generated a model with the best fitness. Based on this multiple regression model, a 10% increase of vegetation volume decreased the air temperatures by approximately 0.14%, while a 10% increase of building volume raised them by 0.26%. Relationships between Chuncheon's summer air temperatures and land cover distribution for the smaller-scale spaces also disclosed that the air temperatures were negatively correlated to vegetation volume and greenspace area, while they were positively correlated to hardscape area. Similarly to the case of Seoul's AWS, the air temperatures for the smaller-scale spaces decreased by 0.32% ($0.08^{\circ}C$) as vegetation volume increased by 10%, based on the most appropriate linear model. Thus, urban landscaping for the reduction of summer air temperatures requires strategies to improve vegetation volume and simultaneously to decrease building volume. For Seoul's AWS, the impact of building volume on changing the air temperatures was about 2 times greater than that of vegetation volume. Wall and rooftop greening for shading and evapotranspiration is suggested to control atmospheric heating by three-dimensional building surfaces, enlarging vegetation volume through multilayered plantings on soil surfaces.

The technologies of 3D spatial information, such as Smart City and Digital Twins, are developing rapidly for managing land and solving urban problems scientifically. In this construction of 3D spatial information, an object using aerial photo images is built as a digital DB. Realistically, the task of extracting a texturing image, which is an actual image of the object wall, and attaching an image to the object wall are important. On the other hand, occluded areas occur in the texturing image. In this study, the ResNet algorithm in deep learning technologies was tested to solve these problems. A dataset was constructed, and the street tree was detected using the ResNet algorithm. The ability of the ResNet algorithm to detect the street tree was dependent on the brightness of the image. The ResNet algorithm can detect the street tree in an image with side and inclination angles.

What are the roles and functions of urban gardening created by citizens in Sujin 2-dong, Seongnam-si? This study has looked into urban gardening in everyday life in a bid to find possible solutions for sustainable urban regeneration. The paper has examined the types, functions, and characteristics of urban gardens in Sujin 2-dong, where the urban restoration project is in progress. This study has conducted primarily on-site inspections and interviews. The research findings are as follows. Most urban gardens in Sujin 2-dong have a vertical structure rather than a regular ground-based one due to lack of land. Six major locations of building a garden include the front of a building, rooftop, top of a gate, stairs, wall, and yard. Rooftop gardens are most common and are built mostly for production purposes. Due to architectural characteristics of this village, there are relatively many stair gardens built mostly for aesthetic purposes. The garden in front of a building has served multiple functions, including formation of entry, privacy protection, and prevention of unauthorized parking. Other than those, detached houses have quality urban gardens built with greater effort and care, while multi-household houses have seen a decrease of stair gardens and an increase of vertical gardens due to their comparatively limited space. By utilizing this research, we hope to show that it is important to understand the local's wisdom and voice for a sustainable urban environment as well as keep these findings in mind during the construction of new buildings. This study would be expected to be useful as primary research for urban gardening in everyday life and alternative ways of urban regeneration.
