  • It is well-known that the scenic visibility achieved in our naked eyes is related with the quality of aerosol condition which is composed of primary and secondary air pollutants. In recent, the IMPROVE organization in U.S.A. has developed two algorithms to estimate the visible length depending on the elements of air pollutant. Using these algorithms, we are to represent the condition of aerosol quality with the well-known scenic images of the observing area so that any one that have no sufficient chemical knowledge may feel and understand the level of air pollution in visuality.

  • Colors change in time corresponding with the value system and aesthetic consciousness of the time. The roles that colors play in painting can be divided into the formative role based on the contrast and harmony of color planes and the aesthetic role expressed by colors to represent the objects. The aesthetic consciousness of the orient starts with the Civility(禮) and Pleasure(樂), which is closely related with restrained or tempered human feelings. In the art world of the orient including poem, painting, and music, what are seen and felt from the objects are not represented in all. Added by the sentiment laid background, the beauty of the orient emphasizes the beauty of restraint and temperance, which has long been the essential aesthetic emotion of the orient. From the very inception of oriental painting, colors had become a symbolic system in which the five colors associated with the philosophy of Yin and Yang and Five Forces were symbolically connected with the four sacred animals of Red Peacock, Black Turtle, Blue Dragon, and White Tiger. In this color system the use of colors was not free from ideological matters, and was further constrained by the limited color production and distribution. Therefore, development in color expression seemed to have been very much limited because of the unavailability and unreadiness of various colors. Studies into the flow in oriental painting show that color expression in oriental painting have changed from symbolic color expression to poetic expression, and then to emotional color expression as the mode of painting changes in time. As oriental painting transformed from the art of religious or ceremonial purpose to one of appreciation, the mast visible change in color expression is the one of realism(simulation). Rooted on the naturalistic color expression of the orient where the fundamental properties of objects were considered mast critical, this realistic color expression depicts the genuine color properties that the objects posses, with many examples in the Flower & Bird Painting prior to the North Sung dynasty. This realistic expression of colors changed as poetic sentiments were fused with painting in later years of the North Sung dynasty, in which a conversion to light ink and light coloring in the use of ink and colors was witnessed, and subjective emotion was intervened and represented. This mode of color expression had established as free and creative coloring with vivid expression of individuality. The fusion of coloring and lyricism was borrowed from the trend in painting after the North Sung dynasty which was mentioned earlier, and from the trend in which painting was fused with poetic sentiments to express the emotion of artists, accompanied with such features as light coloring and compositional change. Here, the lyricism refers to the artist's subjective perspective of the world and expression of it in refined words with certain rhythm, the essence of which is the integration of the artist's ego and the world. The poetic ego projects the emotion and sentiment toward the external objects or assimilates them in order to express the emotion and sentiment of one's own ego in depth and most efficiently. This is closely related with the rationale behind the long-standing tradition of continuous representation of same objects in oriental painting from ancient times to contemporary days. According to the thoughts of the orient, nature was not just an object of expression, but recognized as a personified body, to which the artist projects his or her emotions. The result is the rebirth of meaning in painting, completely different from what the same objects previously represented. This process helps achieve the integration and unity between the objects and the ego. Therefore, this paper discussed the lyrical expression of colors in the works of the author, drawing upon the poetic expression method reflected in the traditional Flower and Bird Painting, one of the painting modes mainly depending on color expression. Based on the related discussion and analysis, it was possible to identify the deep thoughts and the distinctive expression methods of the orient and to address the significance to prioritize the issue of transmission and development of these precious traditions, which will constitute the main identity of the author's future work.

  • The main industry of the Chosun dynasty was farming, which was related to the people's lives in every respect. By the end of the Chosun dynasty commerce was a new industry becoming increasingly more beneficial. I study how these two industries were being expressed in the classic Sijo. The classic Sijo is a main literary genre created by the upper-class. Even though industry was very important for sustaining the Chosun dynasty, Confucian scholars and government officials(members of the upper class) didn't actually work in the industries of farming and commerce. But sometimes they returned to their rural hometowns, because they owed large amounts of land which they let the servants farm for themselves. As the main composers of Sijo were these Confucian scholars and government officials, I study a collection of their Sijo which expresses the life of industry. In order to achieve this goal, I analyze several sides of the classic Sijo : for example, its writers(along with their personalities) throughout different periods: the point of view of persona; and the specific life of industry and the way it is expressed in the Sijo. First, I look at the writers of the different periods and their personalities. During the fourteenth century to the seventeenth century, the main writers of Sijo on the life of farming were Confucian scholars and government officials. During the eighteenth century to the nineteenth century, the main writers of Sijo on the life of farming were Confucian scholars, government officials, and also commoner singers-the unnamed writers. Second, I look at the point of view of persona. During the fourteenth century to the seventeenth century, the personas were the country man(one's lord and master) and the farmer, who was of two kinds of people : i.e., those trying to work together and those really working together. During the eighteenth century to the nineteenth century, the personas were the country man, who was satisfied with his rural life as overseer to farming, and two kinds of farmers : those who farmed very hard by themselves, or those who criticized the failed tax system. Third, I discuss the specific life of industry and the way it is expressed in the Sijo. During the fourteenth century to the seventeenth century, the writers of Sijo expressed, in a general way together in one Sijo, different kinds of work for example, plowing a dry field and a rice field, picking wild vegetables, and cutting rice and weed. During the eighteenth century to the nineteenth century, the writer of Sijo expressed different kinds of work in a more specific way, each in its own Sijo : for example, buying and selling, bringing land under cultivation for farming. weaving, digging for water, and heavy taxation. I look at three aspects of Sijo concerning industry, but there still remain several aspects of Sijo to study, such as those concerning worship of the king, and those concerning high officials, the common people, and the being of things.

  • Chemical reactions occurring in a PEMFC are dominated by the physical conditions and interface properties, and the reactions are expressed in terms of impedance. The performance of a PEMFC can be simply diagnosed by examining the impedance because impedance characteristics can be expressed by an equivalent electrical circuit. In this study, the characteristics of a PEMFC are assessed using the AC impedance and various equivalent circuits such as a simple equivalent circuit, equivalent circuit with a CPE, equivalent circuit with two RCs, and equivalent circuit with two CPEs. It was found in this study that the characteristics of a PEMFC could be assessed using impedance and an equivalent circuit, and the accuracy was highest for an equivalent circuit with two CPEs.

  • 시대의 흐름에 따라 문화적 차이를 극복한 전략적인 제품 디자인의 중요성이 커지고 있다. 이에 따라, 문화의 성향을 파악하여 적절하게 대응할 수 있는 디자인이 필요하지만, 지금까지는 제품에 대한 선호도 또는 감성어휘 중심의 설문조사를 통해 각 문화의 통계적인 경향성을 파악하는 것이 대부분이었다. 그러나 디자인의 선호에 차이를 발생시키는 근본적인 문화 배경적 원인을 파악하지 않으면 체계적이고 지속적인 디자인 전략의 수립이 어렵다. 본 연구는 상이한 문화권에서 발생하는 제품디자인 선호 차이에 대한 원인을 문화적 성향의 차이에서 찾으려고 하였다. 또, 문화적 성향이 제품의 선호에 미치게 되는 원인을 문화연구 방법의 하나인 기호학을 통해 분석하고, 그 관계를 체계적인 모델로 설명하고자 하였다. 이를 위해 한국과 프랑스, 두 문화권에서 웹 기반 설문조사를 실시하여 문화적 성향과 모바일 폰 이라는 제품에 대한 기본적 개념을 파악하고 선호하는 디자인을 조사하였다. 그 결과 첫째, 문화적 성향이 모바일 폰의 개념 형성에 영향을 미쳐 한국에서는 필수품이자 자신을 표현하는 제품으로, 프랑스에서는 필수적이지 않으며 개인에게 유용한 도구로 여기며 그에 따라 한국에서는 디자인을, 프랑스에서는 기능적 요소를 중요하게 생각하는 등의 차이가 발생하는 것을 발견하였다. 또, 상이한 제품개념이 디자인 선호에 차이를 유발하여 프랑스에서는 유(柔)하고 정적인 디자인을, 한국에서는 강하고 동적인 감성의 디자인을 선호함을 분석할 수 있었다. 더 나아가 이러한 결과를 종합하여 기호학적 개념에 입각하여 체계적인 모델을 제안함으로써 상이한 문화에서의 상이한 디자인 선호에 대한 원인을 규명할 수 있었다.

  • The purpose of this is to make sure what the scholar of the Choseon thought the object of aesthetics, and which psychological element did they use to clear the center of the aesthetics. In addition, I consider their way to recognize the human's aesthetic point of view. A literary man in Choseon regarded the five senses as an obstacle which interrupted to see the nature of all things. So they set up the spiritual condition as their aesthetic subject, with suppressing the pleasure through five senses. The goal to make one's mind calm was to cause someone's spirit to activate freely. The condition of the calmness was considered as a process of recovering the human's natural spirit, which was connected to the poetic spirit and became the aesthetic subject. Simultaneously, a literary man at that time set up the condition of the calmness as a subject of objective consciousness, and estimated the common things as a objective existence, which led to the result that all the materials of the poem and the poet could be unified. This aesthetic centra put a premium on the senses caused by contacting with all natural things, and adopted the 'Xing' as a method of expression. This 'Xing' is not a sense based upon one's experience, but a sense which is created of itself. The expression method of 'Xing' caused the reader to feel and express, encourage, and sublimate what they feel through the poem, as well as purified reader's mind.

  • The flower arrangement that human beings interact with the natural plants have characteristics according to their historical background and ethnicity and different aspects of culture related of the flower arrangements have been created by human inspiration and formative ability. The Korean flower arrangement is a product of civilization which originated in the natural environment of the four seasons. As background with the natural unity ideology, the Korean Flower Arrangement makes the life and philosophy of the naturalistic nature that flows in the mind of our nation to the relaxing beauty suited on cultures of ages by the Virtue, the Will, and the Vitality. The Literary Flower Arrangement is, based on the higher human personality and poetic sentiments as ideologies of our traditional oriental philosophy, the formative art made for aesthetic implications of philosophy by consisting plants' characters and tastes without expression of technical skills. In this study, focused on pine tree, in order to clarify that the flower arrangement of our spiritual culture is the Literary Flower Arrangement, make Identifying aesthetic characteristics through, the backgrounds and sources of being expressed by the Literary Flower Arrangement, poetic feelings, symbolism, metaphor, the formative form of flower arrangement, decoding of the flower arrangement genes, and the same time deduce the record of literary work and classify it each era, and establish the Literary Flower Arrangement theory which is the essence of Korean flower arrangement.

  • This paper analyzes the properties of such algorithm that corresponds to the nonlinear adaptive algorithm with additional update terms, parameterized by the scalar factors a1, a2, a3 and Presents its structure. The analysis of convergence leads to eigenvalues of the transition matrix for the mean weight vector. Regions in which the algorithm becomes stable are demonstrated. The time constant is derived and the computational complexities of MLMS algorithms are compared with those of the conventional LMS, sign, LFG, and QFG algorithms. The properties of convergence in the mean square are analyzed and the expressions of the mean square recursion and the excess mean square error are derived. The necessary condition for the CFG algorithm to be stable is attained. In the computer simulation applied to the system identification the CFG algorithm has the more computation complexities but the faster convergence speed than LMS, LFG and QFG algorithms.

  • Reliability prediction provides a rational basis for design decisions such as the choice between alternative concepts, choice of part quality levels, derating factors to be applied, use of proven versus state-of-the-art techniques, and other factors. For this reasons, reliability prediction is essential functions in developing space systems. The worth of the quantitative expression lies in the information conveyed with the numerical value and the use which is made of that information and reliability prediction should be initiated early in the configuration definition stage to aid in the evaluation of the design and to provide a basis for item reliability allocation (apportionment) and establishing corrective action priorities. Reliability models and predictions are updated when there is a significant change in the item design availability of design details, environmental requirements, stress data, failure rate data, or service use profile. In this paper, the procedure, selection of reliability data and methods for space system reliability prediction is presented.
