The discussion on folk painting (minwha) has been continued till recent in various ways. MinWha is applied by painting artists and also utilized as a basic material of design. These are the attempts approved by the viewpoint of the 'Korean beauty'. In saying so, minwha symbolizes for typical types of Korean painting, and is articulated as an aspect of forgotten spirit. However, despite the fact of Minwha's frequent application, and its evident originality, it remains only the thread of the existence. Although minwha has a lot of commonalities and similarities with the characteristics of cartooning, a decisive attempt of cartooning is hardly shown through. Therefore, this paper is aim to classify creative paintings by the distinctive features of minwha, such as exaggeration and abridgment, sarcasm and current affair aspect, common technique of art drawing, caricatured element, expression of an ideal world, various techniques from artist's different comprehension, etcetera and to make opportunity to constructively apply these features in cartoons. The types of minwha are mostly classified by the contents of the painting. However, since the purpose of this thesis is to find caricatured aspects in minwha, it will be largely classified by the elements of animal, plant, human, insect species, finny tribe, feathered tribe, and nature phenomenon. This classification takes advantage of accessibility to understand the characterization of the object, and leads to take a positive approach.

As modern society leads to distinguished, sensuous, and diversity styles, a woman who enjoys putting on Garu makeup appeared on a popular TV talk show in winter 2010, which aroused public interest in the method of Garu makeup. However, as interest in Garu makeup and individuals who put on Garu makeup spread, some began to consider Garu makeup as the imitation of indiscreet Japanese culture or a vulgar culture. Thus the purposes of this study is to understand the characteristics of Garu makeup and its forms of expression by considering its type, origin and style. In turn, this study will provide basic data for the makeup trend and act as an aid to improve the image of Garu makeup through investigating its image and preference. To accomplish this purpose, this study reviewed relevant literatures and web resources, conducted a survey of students who study beauty art at two-year junior colleges in Seoul, and analyzed 195 answers by using SPSS 18.0. The results are as follows: It was proved that in the preliminary inspection of comprehension, 98.3% of college students majoring in beauty art had known Garu makeup, 53% understood somewhat the characteristic and concept of Garu makeup, 36.8% gave preference to Garu makeup. It was proved that in the investigation by the image of Garu makeup, as over 70% of students thought that Ogaru and Yamamba makeup were detestable, but other Garus were lovely and sexy, students perceived as a diversity of images by their own preferences and tastes, and 73% of respondents selected Onegaru as Garu makeup that they gave preference to and wanted to put on. The result of this study represents that mass consumers in the existing culture, who are college students majoring in beauty art and selected as a sample group in this study, reflect the stream of culture and trend, but also demassification, mass customization by their areas of interests and preferences and connective massification of individuals with similar interests.

The purpose of this research is to identify the characteristics of the positive and negative expressions about residential common life between the elderly and the young and present the direction on Homeshare. In-depth interviews were conducted from Feb. to May 2016 to identify the experiences of residential common life with 10 elderly and 11 young. The result is as follows. First, Homeshare dwelling was classified into five themes of human being, residential environment, life, management and emotion. Homeshare unlike ordinary dwelling centered on blood relatives, is characteristic to involve the management that connects between the elderly and young. Second, both the elderly and young were analyzed to be positive about the residential common life. It was shown that the elderly are most positive about human being, whereas young are positive about management and residential environment. The elderly is positive to mutual exchange with the young and young's independent life but the young is positive to factors that support comfortable personal life. Third, negative expression was shown a generation gap between the elderly and the young. The elderly recognized to be negative that young people has lived freely without consideration for the elderly. In order to solve these factors, it is necessary to make improvements through arranging rules for living. Fourth, three themes, human being, residential environment and life, analyzed to be the most important factors to sustain residential common life of Homeshare. The link between management and 3 themes leads to an expansion of positive emotion, which is structurally stable and is expected to increase the sustainability of the residential common life on Homeshare.

Underwater weapon system is required to structurally strong material, since as it is directly exposed to external shock. It should also be using the lightweight material in order to take advantage of buoyancy. Composite materials meet these requirements simultaneously. Particularly in the case of submarine, composite materials are widely used. It is important to have a high strength enough to be able to withstand external shock, but it is also important to attenuate it. In a method for the shock damping, viscoelastic damping materials are inserted between the high strength composite material as a sandwich structure. Shock attenuation can be evaluated in the loss factor. In ASTM(American Society of Testing Materials), evaluation method of the loss factor of cantilever specimens is specified. In this paper, mode tests of the cantilever are performed by the ASTM standard, in order to calculate the loss factor of the viscoelastic damping material by the specified expression. Further, for verifying of the calculated loss factor, mode test of compound beams is carried out. In addition, the characteristics of the material were analyzed the effect on the loss factor.

This study is a basic study to develop standards and foundations for the establishment of traditional Korean gardens and aims to understand the current status of their components and expression methods and identify problems by investigating Korean gardens developed overseas. Nine sites were selected for field surveys and monitoring assessments. The results suggest: Overall, there is a lack of popular generality and temporal characteristics among these gardens, as they are mere reproductions of historical elements. There have also been errors of traditional and experimental interpretations. In terms of design aspects, traditional gardens are primarily compilations of landscape elements and certain ornamental features. In terms of landscape, they tend to be insufficient in parlaying appropriate spatial scales and experiential hierarchies; they also lack considerations of the context of neighbouring landscapes. In terms of guidance and information delivery, there is a worldwide lack, in general, of recognition of Korean gardens, given the broad variety of names attached to them; therefore, name standardization is recommended. In terms of development, management, and use, it is essential that designers suggest plant types, as well as alternatives, that match the characteristics of a given space; a receptive attitude vis-$\grave{a}$-vis the characteristics of their use is required.

In general, the cut or dissolve or etc., collective changeover represents the change of scene in the film. Animation film makes scene's various parts to allow intended sensibility and narrative factors by special manufacturing skill generating frame image one by one and transfer it to the different symbolic dimensional expression. Nowadays sequential scene composition is not any more the unique special treatment for 2D animation according to image handling skill like morphing, metamorphosis, etc. becomes diverse and elaborate. But 2D manual animation makes spectator to be absorbed into different visual dimensions continuously and strongly beyond character and background, namely object and space. that is 2D manual animation's strong attractiveness. Finally these characteristics enable literary function which makes it possible to do delicate metaphorical through full scene composition basis and to communicate a implicative meaning system The analysis about scene broke boundary between symbolic perspective world and plane formative world and it became more diverse and complicated. Hereupon the analyzing the composition basis of formative element in the animation film scene and it's application effect make it helpful to analysis and application in the modern image scene having new absorbing methods

The purpose of this study is to ascertain pattern design element in traditional palaces among those in the neighboring three nations of East Asia, notably Korea, China and Japan. The basic assumption underlying this study is that these northeastern Asian states have been developed a unique inter-cultural ties over long periods of time in history, culminating in their respective design cultures. Undoubtly the ultimate goal to be pursued, by so doing, has to be inquiry into the identical prototype of Korean pattern design element. In the West, the pattern is appreciated by an aesthetic level, but the East Asian pattern is a symbolic alphabet deeply rooted in religious and folk beliefs. The difference of the respective country comes from the expression style of the pattern the Chinese express the magnificent pattern with various color, the Korean do the moderate pattern with harmonious color with the nature and the Japanese do the stylized pattern with the material color. To sum up similarities and dissimilarities among the design element in traditional palaces of Korea, China, and Japan is as the following : It is to be noticed that the mainly common characteristics of the artistic design are 'naturalism', 'harmonious ideas 'and 'confucianism'. But the representation style of the design element is differed from the country.
