PURPOSES : Traffic accidents at intersections have been increased annually so that it is required to examine the causations to reduce the accidents. However, the current existing accident models were developed mainly with non-linear regression models such as Poisson methods. These non-linear regression methods lack to reveal complicated causations for traffic accidents, though they are right choices to study randomness and non-linearity of accidents. Therefore, to reveal the complicated causations of traffic accidents, this study used structural equation methods(SEM). METHODS : SEM used in this study is a statistical technique for estimating causal relations using a combination of statistical data and qualitative causal assumptions. SEM allow exploratory modeling, meaning they are suited to theory development. The method is tested against the obtained measurement data to determine how well the model fits the data. Among the strengths of SEM is the ability to construct latent variables: variables which are not measured directly, but are estimated in the model from several measured variables. This allows the modeler to explicitly capture the unreliability of measurement in the model, which allows the structural relations between latent variables to be accurately estimated. RESULTS : The study results showed that causal factors could be grouped into 3. Factor 1 includes traffic variables, and Factor 2 contains turning traffic variables. Factor 3 consists of other road element variables such as speed limits or signal cycles. CONCLUSIONS : Non-linear regression models can be used to develop accident predictions models. However, they lack to estimate causal factors, because they select only few significant variables to raise the accuracy of the model performance. Compared to the regressions, SEM has merits to estimate causal factors affecting accidents, because it allows the structural relations between latent variables. Therefore, this study used SEM to estimate causal factors affecting accident at urban signalized intersections.

Gilles Deleuze highly evaluated Baroque as the expression body that implements the fold theory, a philosophical thinking about the nature of beings. This can be seen as a meaning that Baroque implements the essence of the world, or the power constituting that essence. In addition, the beauty of Baroque focuses on 'New Harmony' the sum of partial forms caused by each element, and not Platonic harmony. he evaluated the aesthetic of Baroque costume as 'acquisition of liberation and autonomy', 'derived force from infinite spiritual forces'. This study analyzed the contents of the Aesthetic of Baroque costume based on the reviewed Deleuze's folding theory, Baroque aesthetics, and views of Baroque costume. As a result, it inferred the aesthetic of Baroque costume into four types, which are as follows: open structural openness, overlapping structural dynamics, integrated structural diversity, and relationship structural integrity. This study analyzed the aesthetic of Baroque costume based on Deleuze's philosophical thinking. The analysis showed that its aesthetics, which focused on "New Harmony", created energy of life and a venue for expression of power, as the aesthetics eliminated the prejudice of complexity and excessive decoration. In addition, Baroque costume is not the simple historical costume of the past. Instead, it is one of power and spirit, still existing in modern fashion. Baroque costume's formativeness and Paradigm can be said to provide the creative principle important for modern fashion because the aesthetics implemented in Baroque costume accepts free spirit, new challenge, difference and diversity, and is similar to the spirit pursued by modern art and fashion.

본 논문에서는 StrAuto를 이용하여 구조물의 형상 변경을 통한 대안을 생성하고, 이에 대한 최적화를 수행하는 과정을 상세하게 다루었다. 비정형 대공간 전시장 구조물을 대상으로 전체 형상을 파라메트릭하게 디자인하고, 가장 폭이 넓은 경간의 구조 형상을 변경하면서 물량 변화를 관측하여 최적안을 도출하였다. 기존 연구들에서는 형상 변경의 제약 때문에 대부분 단면과 물성을 통한 최적화를 수행하는데 그쳤으나, 본 연구에서는 형상 변경이 가능한 부분을 찾아내어 StrAuto의 가장 핵심적인 능력인 형상 변경을 통한 최적화를 수행했다는 점에서 중요한 의미를 지닌다. 형상 변경으로 충분한 여유를 확보하고 단면 최적화로 물량을 줄이는 프로세스를 통해, 대공간 구조물의 일부만을 대상으로 하면서도 전체 물량의 11.7%를 줄일 수 있었다.

Even though Gothic architecture, one of the most technologically complex sophisticated structural systems, has been interpreted by art and architectural historians since the nineteenth century, we still cannot entirely comprehend either the medieval builder's constructional technique and structural knowledge or the meaning of Gothic architectural elements. The major reason is that contemporaneous written documentation concerning design methods and constructional techniques of medieval architecture is lacking. In 1955, the Bibliotheque Nationale in Paris exhibited the sketchbook of the thirteenth century architect Villard do Honnecourt. After the exhibition, analysis on the architectural drawings of Villard's sketchbook had reported widely. Most of analysis on Villard, however, has been on his drawing and artistic style, and there has been very little published analysis of his profession and question on the author of the sketchbook. Thus, the purpose of this study is to investigate the characteristics of the sketchbook and identify the artist who drew it. The sketchbook poses a number of unsolved questions. There is no doubt that several hands have contributed some drawing with appropriate captions, particularly in the section devoted to the application of practical geometry to problems of masonry and carpentry. Scholars have assumed and revealed that it was not made by only one person, and it dealt too many different fields and styles. Through this study, the sketchbook drawings consist of five different styles and person (original painter, master1, master2, master3, and the last owner), and they, not Villard, just redrew the original drawings and bound the sketchbook. Therefore, Villard de Honnecourt was just a mentor of the sketchbook and he did not participate any writing and drawing in the sketchbook.

The purpose of this study is to find the relationship between hightech architecture and digital one through the discussion on Karl B tticher's view on tectonic in 19th century. The discussion of tectonics which has not been brought up until recently. Since there are no studies regarding contemporary architecture relating to Karl B tticher's view on tectonic, so it is fairly significant to study Karl B tticher's conception, discussion and relationship of contemporary architecture. To study the essence and meaning of Karl B tticher's view on tectonic in 19th century, we will analyze each examples of hightech architecture and digital architecture through Karl B tticher's dual form. B tticher insist that dualistic relationship is united and produced simultaneously. Because they have so closed relationship each other, it's impossible to apply only decoration without structure. Therefore they have mutual assistant relationship. A relationship can be found between hightech architecture's technology and structural symbol that Karl B tticher tried to find in steel which is new material ornament. Digital architecture can be confirmed as images which are made of maximum expose through consistent dynamics of structure. Karl Btticher try to find structural symbolism between new meterail, iron, and decoration. In modern architecture it has the closed relationship with high-tech technology.

이 논문의 목적은 추가령 열곡 내에 발달한 단층구조를 확인하려는 것이다. 열곡에 관한 이해는 한국의 구조지형 발달에 관한 실태를 파악하는데 매우 중요한 의미를 갖는다. 그러나 아직까지 열곡형성에 관한 메카니즘이나 형성과정에 관한 논의가 확실하게 정리되지는 않았다. 야외조사를 통해서 얻은 자료를 기초로 하면 이 지역에 단층구조가 존재하는 것이 확실하다. 그러나 열곡이 매우 길고 넘어서 단층구조 전체에 대한 증거를 확인하기는 매우 어려운 점이 있다. 이 연구에서 IMAGEM은 매우 유용한 방법론의 하나이다. IMAGEM은 Electomagnetic Instrument Inc. 에 의해 개발되었고 $0.001{\sim}20,000Hz$를 커버한다.

The importance of environment has come into focus recently, and this has led to increased attention on zero waste fashion design as a method to minimize waste from the production stage of fashion goods. The purpose of this study was to analyze the development method types and the characteristics of zero waste fashion design in order to study the eco-friendly meanings of zero waste fashion design, as well as its meaning as creative design development methods. Through the case analysis of recent designs, the design types of zero waste fashion design were largely classified into cut and sew, folding, draping, and non-woven types, and they were classified again according to the characteristics of production process. According to the result of analyzing fashion design development methods of zero waste fashion designs based on the process of completing design, they were classified into pattern making, computer programming, draping, assembling of the unit, and non-woven moulding methods, and the aspect of combined use rather than utilization of one method appeared. Formative characteristics of zero waste fashion design included decorative beauty, formative beauty, and transformable beauty and its design characteristics were fortuity and unexpected properties, breaking stereotypes, structural flexibility and futuristic innovation.

From the research which sees the building which uses a natural control method with ecological architecture, continuity tried to divide the building which uses a physical control method with sustainable architecture. Ecological architecture analyzes the microclimate of the area and applies mining and natural ventilation leads and that the interior environment controls, the condition of the site actively and there is a possibility of seeing. Also sustainable architecture which is possible to lead and recycling and reuse of the resources and energy cyclic process of the construction resources to lead and the interior environment to control. Therefore the case where the facility system and structural system become integrated design organically in natural circulating method is many. Specially the sunshade system and double skin system are combined and structural system of the building and there is a possibility of having the envelope which form is feature. Today the buildings lead and the system integration process where the integral parts are systematic is demanded the interior environment which and an external form and that, they make they are there is a possibility of seeing. the environmental building which hits joins in with natural control method and the structure and facility system are integrated and has the tendency which is developed and there is a possibility of saying that a meaning with the alternative construction will be able to reduce the resources and an energy.

The purpose of this study is to explore structural relationship between cognitive factors and emotional factors in predicting behavioral intention of duty-free users. This study conducted questionnaire survey on 246 users of duty-free shops and analyzed it by using structural equation. As the result of the study, attitude was significantly associated with both desire and behavioral intention. Subjective norm had a significant impact on desire, but had no significant imfact on behavioral intention. Whereas perceived behavioral control did not have a significant influence on desire and intention. Desire, which plays mediating role as a major variable in goal-directed behavioral model, turned out to not only have significant impact on behavioral intention but has the strongest effect as well. This study has its academic meaning in that it explored factors which have effect on decision-making process of duty-free users focusing on goal-oriented behavioral model, which is one of integrated psychological models. In practical terms, this study can be used as a basic material for corporations to establish goals in domestic duty-free shops.
