The meaning of light is not always developed aspect in process of architecture history as essence worth of the architecture. It means that architectural light is not affected simple development of civilization, but it has more complex aspect. The technology of applying architecture has continuous development of society that light is possible to extend quantity by development of technology because light is component not simple material or tools but strong worthy aspect, quality development of architecture comes true by exact understanding and application. Conversion from medieval society to modern society begins at the Industrial Revolution has new skills and materials, the architectural conform general space filled with non-characteristic light, and it gives rising to pursuit Utopia is not exist frequently. In result, light of metaphysical meaning is diminished and exterminated. In other hand light seems to be tools by development of technology in modern society, recovering its own meaning in other aspect. That light makes perfect image of architecture not by finite meaning only for simple space but by expressing strongly point that unify the whole architectural composition. Light is free from partial material of architecture. Light activates major composition through high-technology, and has possibility to carry out the essential worth animate architecture. The light expresses relative speciality for sense of place recognizes major component which the human being lives in and conform the real meaning of architecture.

In contemporary architecture, there are developing aspects of variety design in material, image and form. These various architectural trends even change classical media and this concept is based on the background of current idea - digital, information-media, imagination with paradigm. So this study aims to show the present status of the expressions in the contemporary architecture of Korea under its media situation. Namely usual thoughts for design have to be changed because our life is surrounded by many kinds of powerful media signs and various mixed cultural circumstances. And like this, we know for study about the relation between media and current architecture, still more Korean present condition. In chapter one, the background, purpose and method of study are explained. In chapter two, the general concept of media is inquired in this study. In the process of searching for the formingbasic background, the characteristic of this study is understood. In chapter three, this study inquires the aspect of media expression in modern architecture. In chapter four, according to chapter three, this study shows the present status of media expressions in the contemporary architecture of Korea. In chapter five, a synthetic conclusion is presented.

Grout injection is mainly used for permeability reduction and/or improvement of the ground by injecting grout material into pores, cracks, and joints in the ground. The oscillatory grout injection method was developed to enhance the grout penetration. In order to verify the level of enhancement of the grout, field grout injection tests, both static and oscillatory tests, were performed at three job sites. The enhancement in the permeability reduction and ground improvement effect was verified by performing a core boring, borehole image processing analysis, phenolphthalein test, scanning electron microscopy analysis, variable heat test, Lugeon test, standard penetration test, and an elastic wave test. The oscillatory grout injection increased the joint filling rate by 80% more and decreased the permeability coefficient by 33-68%, more compared to the static grout injection method. The constrained modulus of the jointed rock mass was increased by 50% more with oscillatory grout injection compared to the static grout injection, indicating that the oscillatory injection was more effective in enhancing the stiffness of the rock mass.

This study presents the estimation of crack depth by analyzing temperatures extracted from thermal images and environmental parameters such as air temperature, air humidity, illumination. The statistics of all acquired features and the correlation coefficient among thermal images and environmental parameters are presented. The concrete crack depths were predicted by four different machine learning models: Multi-Layer Perceptron (MLP), Random Forest (RF), Gradient Boosting (GB), and AdaBoost (AB). The machine learning algorithms are validated by the coefficient of determination, accuracy, and Mean Absolute Percentage Error (MAPE). The AB model had a great performance among the four models due to the non-linearity of features and weak learner aggregation with weights on misclassified data. The maximum depth 11 of the base estimator in the AB model is efficient with high performance with 97.6% of accuracy and 0.07% of MAPE. Feature importances, permutation importance, and partial dependence are analyzed in the AB model. The results show that the marginal effect of air humidity, crack depth, and crack temperature in order is higher than that of the others.

As environmental issues have been increased globally, eco-friendliness in the construction area, which accounts for more than 30% of total GHG gas emission has being urged. In response, the Korean government has implemented G-SEED(Green Standard for Energy and Environmental Design) certification from 2002. However, total number of certified apartment buildings is only around 1% of total number of approved apartment buildings. As a basic research to find out reasons of low rate of the certification, this paper analyzes consumers' decision-making process in G-SEED certified apartment building market comparing to non G-SEED certified one and draw System Dynamics modeling based on causal relationship. As a result, consumers' demand for the certified one is increased by 'Perceived Relative Utility' which is resulted from comparison process with non-certified one. The 'Perceived Relative Utility' is ascended upward steadily by 'Relative Perceived Price' considered as relatively short-term effect and 'Favorable Image of Certified Housing' referred to long-term effect.

본 연구는 한국의 문화정체성을 표현하는 대표적 이미지어들을 도출함으로써 디자인 분야에서 활용할 수 있는 한국의 정서와 이미지를 구체적인 어휘로 제시하는데 목적이 있다. 연구 방법으로는 1990년대에 발표된 복식과 건축 디자인 논문 중에서 한국의 이미지를 현대적 의미로 재해석한 논문을 중심으로, 디자인 요소, 디자인 원리, 추상성, 표현성 그리고 기능성의 요인과 관련된 이미지어를 유형별로 범주화하여 분석하였다. 복식과 건축디자인 분야를 대상으로 한국의 이미지에 대한 공통성과 차별성을 규명한 결과, 이제까지 보편적으로 인식되어오던 한국의 이미지와 함께 새로운 측면도 발견할 수 있었다. 즉, 이제까지 한국의 문화 정체성을 나타낸다고 인식되어온 무채색, 소박함, 한과 비애, 간접적 표현 등을 나타내는 이미지 외에도 화려한 색채, 고귀함, 즐거움 등과 같은 적극적이고 능동적인 표현도 한국의 문화정체성을 나타내는데 중요한 비중을 차지하고 있음을 알 수 있었다. 또한 건축디자인에서는 복식디자인보다 기능적이고 합리적인 이미지가 도출되었다.

We present a non-photo realistic pen-ink drawing method for outlining and shading of the input image. Especially, we focus on the detailed illustration of the image of which stroke's direction is important. The pen-ink renderer is an alternative display models user can generate traditional illustration renderings of their photo realistic image. The previously proposed pen drawing methods produce feasible description in general image but it is difficult to express in detail for the sophisticated images that need to consider the direction of stroke for each image region. In order to overcome the disadvantages of the conventional method, a direction vector is extracted from a tensor field and we determine a stroke's direction in consideration of not only an edge area but also a gradient of a surrounding area in the image. For more detailed description for the sophisticated image, we generate white noises based on the light and shade of the input image and determine the direction and length of the stroke by using the tensor field for each generated white noise. The proposed method works particularly well for traditional architectural images where the direction and detailed description of the pen is important.

There has been active research in image classification using deep learning convolutional neural network (CNN) models. ImageNet large-scale visual recognition challenge (ILSVRC) (2010-2017) was one of the most important competitions that boosted the development of efficient deep learning algorithms. This paper introduces and compares six monumental models that achieved high prediction accuracy in ILSVRC. First, we provide a review of the models to illustrate their unique structure and characteristics of the models. We then compare those models under a unified framework. For this reason, additional devices that are not crucial to the structure are excluded. Four popular data sets with different characteristics are then considered to measure the prediction accuracy. By investigating the characteristics of the data sets and the models being compared, we provide some insight into the architectural features of the models.

This research seeks to analyze western men's costume in the Baroque era in relation to men's physical beauty from its most detailed and interesting perspective to fomulate a plausible reasoning related to the aesthetic sense of body as expressed in men's costume. This research used national and international books, theses and internet data upon which to base a literature review for a correct understanding of Baroque style and at the same time empirical research to analyze the body image expressed in men's costume. The Baroque style expressed in the 17th century costume offered a dynamic feeling through wavy curves, and its brilliant and colorful decorations created a passionate and charming mood resembling a flame. Accordingly, this research studied the body image as it appeared in the form of 17th century western men's costume by dividing it into the contact beauty of the human body and the manner of hiding the architectural beauty of the human body. First, the exposed silhouette by clothing coming into contact with the human body could be found mainly in upper-class men's costume in the first half of the 17th century. The shorter and tighter doublets and knee breeches could be analyzed in terms of erotic imagery that emphasized masculinity, aristocratic imagery that stressed a distinctive status, and geometric imagery that expressed a triangular pattern. Second, the constructive expression by hiding the human body could be found in upper-class men's costume starting in the mid-17 century. The wearing of the justaucorps could be studied in terms of how it came into contact with the beauty of the human body but also how this clothing style the hid the architectural beauty of human body.

Aldo Rossi explained Roman Forum as a significant urban artifact, because Roman Forum analogically showed not only an image of Roman Empire but also a figure of primitive design for its region. Thus the comparison and analysis between characteristics of Aldo Rossi's architectural works which are based on the theory of 'Analogical city' and the forums, the urban artifacts, was proceeded in this study. Consequently, it was discovered that Aldo Rossi had used his analogical thinking from the forum for his architectural languages such as gable roofs, square windows with depth, columns and so on. His analogical use of organizing spaces, such as courtyard type and pillar corridor type, has also shown that their types came from forum spaces. His analogical aspects of the forum: a space where urban images are analogically formed; were expressed in the 'Theater of Science' with the urban architecture form as the actor and the Theatre as the stage for analogical urban performances. Nevertheless, the expression of primitive design which divides the Roman Forum from other forums was actualized in 'the Theater of the World'. He not only analogically used types from Roman Forum in architectural design but also used boat in Water space, which decided the lifestyle and culture of Venice even before the civilization, to express the primitive design of Venice. Consequently, Aldo Rossi, by aiming the severance from the tradition, provided the possibility of explaining the newest modem type within the historical meaning by forming type which finds its continuance in history through 'the Theater of the World' and through analogical thinking along with the level of modern culture, to our urban architectural atmosphere that has lost its historical meanings.
