  • The ecological expression of art in modern society takes the harmonious developmental relationship between man and nature as an element and combines it with the various manifestations of painting as an expression of ecological artistic development. The necessary relationship for the harmonious development of nature is accurately articulated, and the ecological changes in people are expressed in integrated materials that inspire human reflection. In the pursuit of material pleasures, mankind is neglectful and indifferent to the environment. The development of composite painting in art and ecology is a process that more reveres the harmony between man and nature as well as satisfying the creative value of the work. After systematic evaluation and research, people have engaged in various structural forms of composite art painting development in the long history of art development, focusing on the integration of environmental and ecological culture.In the process of nature education going through development, the comprehensive practical development of nature education is enhanced and efforts are made to feel new ecological art ideas and new ways of valuing environmental protection. In this paper, an observational study of eco-art will be carried out, starting from the theory of hierarchical division and analyzing the contradictory relationship between man and nature. Recognize nature, understand it and feel it through eco-art painting. The analysis of the contradictory relationship between man and nature is combined with the identification of various types of information that give value to the environmental protection public, and the combination of ecological painting and nature art to achieve an upgrade of the environmental protection idea of the value of painting.

  • Nature is suiting to the objective of oneself, structurally safe and functional. It continues to transform itself into various forms and has aesthetic beauty. By analyzing how nature's organic property has been expressed in different cases of furniture design, which has objective purpose, this research presents designing pathway to induce nature's organic oder into the furniture design. Simile expression type clearly shows its form through exposing the natural material that it is made out of. Visually, esthetic beauty can be emphasized and mentally it can provide pleasantness. Metaphorical expression type only hints the original material that was used to reproduce. Under the same condition it can have subjective perception and it needs to be used suitably at the right place and time. Abstract expression type it might be hard to recognize the original material visually since it went through many transformation in expression, however it can stage extreme and mysterious atmosphere. Furniture designs employing these three types can have functionality as well as decorative and serve variety of change in the existing uniformed interior space, and it can also satisfy individual's need with practicality and provide aesthetic beauty.

  • Interior designer Sugimoto Takashi uses salvaged material and natural thing for aesthetical purpose. These material performs not just as fun stuff but as design tool in order to set up cultural meaning which modern society always lacks for. The method of communicating the meaning is the multi-layered trace on them. There are three types of trace. They are harsh texture of surface, untrimmed outline, and gathering & arrangement. Through these formation methods of trace, Sugimoto can suggest various curtural meanings such as vanishing value of old-fashioned lifestyle, primitive energy of nature, and sincere touch of somebody. As a result, the trace in Sugimoto's design is an endeavor to exist tradition(the long ago) and nature(the far away) in here-and-now interior space.

  • The microcapsules containing fragrant oil as functional material were prepared by in-situ polymerization with prepolymer that was made from melamine-formaldehyde (MF) as wall material of microcapsules. The effects of polymerization variables, such as the nature and concentration of surfactants, stirring rate, and stirring time, on the size and distribution of the particles were investigated. Fourier transform-infrared spectroscopy (FT-IR), thermal analysis, particle size analysis, scanning electron microscopy (SEM) observation were used to investigate the characteristics of microcapsules. Through the FT-IR and SEM analysis, we found that the prepared microcapsules were containing fragrant oil and the shape of particle was spherical. The nature and concentration of surfactants, stirring rate, and stirring time had profound effects on the particle size and particle size distribution.

  • The purpose of this study is to investigate sensibility words related with eco-friendly in the two media fashion magazines and internet newspapers and to analysis their appearance frequency and changes by the year through 1999~2010. Most frequently used words are 'nature, eco, cotton, natural fiber, health, fresh, clear, preservation, harmony, com fiber, and Lohas'. The words are divided in 4 groups: 'Nature/Environment, Material/Fiber, Human, and Adjectives/Micell'. A point of appearing time is analyzed: 'ecology, memory-shape material, organic, spa' were used before 2000, 'nature environment, eco-friendly, stretch material, wellbeing, substitute, recycling' were in 2000-2001, 'smart material, eco material, green' in 2002-2003, 'coolbiz, Lohas, natural dye' in 2004-2005, 'herb medicine, sustainable, warmbiz' in 2006-2007, 'greensumer, greenlife, solar energy, forest bath' in 2008-2009. Looking into their changes, in early 2000, the words of eco-friendly emotion and sensibility had appeared frequently relatively, but later on they decreased, and again recently increased showing highest appearing frequency. 'Nature/Environment' words have appeared recently very much, while 'Human' sensibility words have not changed much or decreased a little. 'Adjective/Micell' words has increased little bit recently. 'Material/Fiber' words showed decrease at fashion magazine, while they increased at the pages of internet news.

  • An interest in modern space is expanded to search for the relationship among human, space and environment, not limited the fixed or typical material place. For grasping and analyzing the characteristics and aims of modern space, this study is focusing on 'Dionysian outlook on nature' among the Nietzsche's philosophies. Nietzsche's 'Dionysian outlook on nature' based on his 'philosophy of creation and positiveness' has great implications for modern space because it focuses on not only circulation of existence and creation but also dynamic vitality the mostly. The reason is that modern space is required by the tendency changing the goal and aesthetic value by planner or user, not fixed and unchangeable any longer. The concept of space in modern construction is developed by forming various paradigms. Especially, various examples based on Nietzsche's Dionysian outlook on nature, philosophy of creation and positiveness, will be analyzed and possibility of new spatial concept's extension will be researched.
