응력 변형율의 관계가 시간에 대한 미분의 형태로 나타나는 비선형 탄소성 혹은 점탄소성 재질을 갖는 구조물이나 지만의 거동 문제를 유한요소법 등의 방법을 이용하여 해결하려고 하는 경우 주어진 외력에 의한 새로운 응력이나 응력 강화 현상을 표현하는 여러 재료 상수값들을 구하기 위해서는 적분을 요하게 되며 일반적으로 수치해석적 방법에 의해 수행된다. 이러한 수치해석적 적분방법은 보다 정확한 결과를 얻기 위하여 알고리즘 자체의 정확성과 안정성이 요구된다. 정확성은 수치해석적 적분방법이 적용될 수 있는 step size에 관계없이 거의 동일한 결과치를 얻을 수 있느냐 하는 것을 말하고 안정성은 큰 step size에서도 수렴된 결과치를 얻을 수 있느냐 하는 것을 의미한다. 그 뿐만 아니라 비교적 복잡하고도 그 대상영역이 큰 문제를 해석하고자 할 때는 수렴속도 또한 빠른 해석방법이 바람직하게 된다. 따라서 본 기사에서는 여러가지 가능한 수치해석 적분 방법을 소개하고 그들의 장단점을 논하고자 한다.

본 연구는 적은 감쇠(damping) 효과를 가지면서도 안정적으로 의복의 움직임을 생성할 수 있는 시뮬레이션 방법을 제안한다. 최근 의복 시뮬레이션 분야에서는 뛰어난 수치적 안정성을 지닌 암시적 적분법(implicit integration)이 널리 이용되어 왔다. 그러나, 암시적 적분법은 선형화 과정에서 과도한 감쇠효과가 발생하고, 이 감쇠효과는 내부 변형 없는 회전이동 시에도 과도하게 나타나므로, 옷감의 회전 이동이나 주름의 자연스런 움직임을 크게 방해한다. 본 연구는 불필요한 감쇠효과를 줄이고 안정적으로 의복의 움직임을 표현할 수 있는 새로운 암시적 적분법을 제안한다. 제안하는 방법용 선형화 과정에서 발생하는 내부 감쇠력을 회전이용이 아닌 순수한 내부 변형에 대해서만 발생하도록 모델링하며, 이렇게 계산된 내부 감쇠력을 역학식에 안정적으로 반영한다. 실험 결과는 제안하는 방법이 기존의 방법들에 비해 보다 다양한 재질의 옷감을 과도한 감쇠 효과 없어도 안정적으로 실시간에 생성할 수 있음을 보여주었다.

The Tuck, an important component of modem clothing design, was analyzed through various sources of literature comprised chiefly of domestic and imported fashion magazines from 2000 to 2003. The results were as follows: 1) The Tuck was organized in horizontal, perpendicular, oblique and radial directions. Application methods included repetition, gradation, radial arrangement, sequence and alternation of individual lines. 2) The Tuck was found in a variety of forms and uses. But due to structural characteristics, its function is more psychological and aesthetic than functional. The aesthetic properties of the Tuck included rhythm, optical illusion, abstraction, and material. The structural property of the Tuck occasionally substituted bust or waist darts. 3) The individuality and originality of the Tuck was used in unpredictable ways to give spatial ornamentality and emphasis on material. This enabled aesthetically unique designs to arise. To summarize, the Tuck, a component of clothing design as a formative art, was used in a variety of methods towards developing creative clothing design.

새로운 탄생을 위해 과거의 것을 재조합하는 역사적 절충주의는 오늘날 과거로 회귀하고픈 현대인들의 요구에 부합하며 환영받고 있다. 본 연구는 복식에 표현된 역사적 절충주의 양식을 파악하기 위해 건축을 통해 그 특성을 규명하고 이를 복식에 적용시켜 19세기 복식은 복식사 문헌을 바탕으로 20세기를 대표하는 1990년대의 복식은 $\ulcorner$콜렉션$\lrcorner$지를 중심으로 복식의 역사적 절충주의 양식을 살펴보았다. 연구 결과, 서로 다른 두 장르에서 펼쳐진 역사적 절충주의는 비슷한 시기가운데 1)형태 참고를 특징으로 하는 조형성, 2)장식적인 아름다움을 특징으로 하는 장식성, 3)새로운 재질과 발전된 기술을 기반으로 하는 기술성, 4)불투명한 시대 경향을 지시하는 모호성이라는 조형적 특성을 나타내었고, 이로 인해 건축과 복식의 문화적 공유성은 재확인되었다. 이처럼 복식의 역사적 절충주의를 통해, 과거의 힘이 무엇이며 현재에 어떠한 의미를 지니는가를 상기한다면 복식사의 중요성은 더욱 부각될 것이다.

This study investigated the effects of costume styling, color and texture on character expression in the movies "All About My Wife" and "Marriage Blue". As a study method, the main scenes were captured from the DVD image and the costumes of the main characters were analyzed to examine how the costumes express the personality change according to the story development of the characters. The characters in "All About My Wife" and "Marriage Blue" were studied to see how their personality changes as the story develops and how the costume supports the personality change of those characters. It was checked that costume contributes to effectively deliver the emotion of the characters to audience. In the movies, costume plays an important role in completing the character, and styling, color, and texture of the costume are one of the important means of expression. In a movie, costumes, styling, color, and texture contribute towards development of each character's character. And these elements act synergistically by acting simultaneously rather than independently, thus defining the image of the costume and playing a role in building characters. Movie directors persuade the audience by expressing their intentions in various ways. Among them, movie costume is one of the most effective expression tools. The styling, color, and texture of the clothes are practical and effective methodology that will create a character, so I hope that the field of film art will be researched extensively in the future.

Purpose : This study is intended to understand the sensitometric characteristics and the emulsion properties of the commercially available CEA TVS film in comparison with the Kodak X-Omat V film. Materials and Methods : For this purpose, we have formulated an analytic expression of the characteristic curves for x-ray film exposed to mixed radiation of electrons, photons, and visible light. This mathematical expression was developed based on reaction-rate and target-hit theories. Unlike previous expressions. it relates optical density to emulsion properties such as grain size and silver bromide content We have also developed a quantity which characterizes the film response to visible light relative to that to photons and electrons. This quantity could be expressed as a function of grain area. Thus, we have developed mathematical expressions and quantities with which the emulsion properties of the films can be revealed based on the sensitometric characteristics. Demonstrating the use of this analytical study, we exposed CEA and Kodak verification films to the mixed radiation of electrons, photons, and visible light, and interpreted the experimental results accordingly. Results : We have demonstrated that: (1) the saturation density increases as the silver bromide content increases, (2) the time required to reach the threshold dose (to which the film begins to respond) when films are exposed to visible light decreases as the grain size increases, and (3) the CEA film contains more silver bromide. whereas the Kodak film contains larger grains. These findings were supported by the data provided by the manufacturers afterward. Conclusion : This study presented an analytical and experimental basis for understanding the response of X-ray film with respect to the emulsion properties.

When expressing Christ visually in the medieval Christian painting, the most important issue was how to express the divinity as Son of God and the humanity as attribute of human in a balanced manner. The purpose of the study is to examine both formative and symbolic characters of divinity and humanity on the Christ's body and clothes in the Medieval paintings, Transfiguration of Christ. In the paintings, Christ's body is definite evidence to show both his divinity and humanity. In connection with the body, the clothes reveal Christ's humanity and divinity as well. Through this research, the study found that the divinity and humanity on the Christ's clothes in the Transfiguration of Christ were as follows: Blue, gold, purple, white and bleaching effect are the emblem of divinity, and red and color contrast effect with a high chroma stand for humanity of Christ. In addition, unstructured wrinkles of clothes reveal Christ's divinity, on the other hand, structured drapery shows his humanity through emphasizing volume of the body. Finally, divinity of Christ is shown on the gold clavus and red clavus intensify his humanity. Medieval Christian paintings are products planned out to express Christ's dual nature. There is a significance that the paintings represent the profession of painter's faith and the dogma of the era. Furthermore, they suggest the importance of the image to deliver the abstract concepts by visualizing.

This study is on the usage of bojagi recorded in Yeongjo Jeongsun Wanghu garye dogam uigwe. Major findings are as follows. The eighteenth century marked a period of entrenchment of Neo-Confucianism in the Joseon dynasty and the royal wedding was a tool to propagate Neo-Confucian values to the people. The bojagi used at King Yeongjo and Queen Jeongsun's wedding were made of simple red silk produced domestically to avoid extravagance. Uasge of costly flower-patterned silk from China was restricted to comply with the rules of the Kukhon jeongrye, which codified the royal marriage ceremony and the Sangbang jeongrye, which regulated royal attire. This modesty also shows King Yeongjo's determination to abandon lavishness.
