Recently, as interest in environmental issues increases, minimizing carbon dioxide generated during cement manufacturing is a problem to be solved. In order to solve such a problem, it is required to use an industrial by-product of recycled aggregate, blast furnace slag, and circulating fluidized bed boiler fly ash to replace it on the basis of geopolymer(=cementless). This study examines the characteristics of eco-friendly artificial stone according to the mixing ratio of geopolymer-based recycled aggregate. As a result of the experiment, when the addition rate of the alkali stimulant was 15% and the mixing ratio of the circulating aggregate was 70%, the flexural strength and compressive strength were the highest. Density and water absorption decreased as density of circulating aggregates increased and water absorption increased. However, when the mixing ratio of the circulating aggregate exceeded 70%, the flexural strength and compressive strength decreased. Therefore, in order to obtain strengths meeting the KS standards, the mixing ratio of recycled aggregate was set to 70%, and artificial stone was manufactured using industrial by-products.

The importance of indoor air quality management has recently been highlighted due to environmental problems such as indoor air pollution. Among indoor air pollutants, carbon dioxide occurs in cooking, heating, burning, and causes forgetfulness, dementia and amnesia. Radon, which occurs in building materials, soil and ground, is a type 1 carcinogen that causes lung cancer in the body through breathing. These substances can be released from the room through ventilation, but there is a limit to reducing the amount of indoor activity due to reduced ventilation conditions due to increased indoor activity time. However, these substances can be removed from the gas by adsorption. The purpose of this study was to identify the properties of granular active and powdered active white soil and mix them to make cement-based active white soil adsorbent matrix for carbon dioxide, fine dust and radon gas adsorption, and to evaluate indoor air improvements according to the mixing scale. The results of the experiment showed that active carbon dioxide adsorption performance increased for carbon dioxide and radon as the exchange rate increased through physical adsorption. In particular, the higher the replacement rate of the granular active bag, the better adsorption performance was shown.

Nowadays, active teachers expend much time and effort in preparing for classes. Especially, the basic formative calsses in art education have much effect when they are done with a lot of material(plaster casts, etc.) and lighting effect, but not in real. Proposed web-based learning instrument makes possible basic formative classes with simple operation by loading several materials and lighting operator on the web. In this paper, we propose web-based learning instrument to improve basic formative classes. Students will easily be able to express shadow and shade by lights with this web-based learning instrument in basic formative classes.

Environment artworks occupy the diverse spaces of architecture not as one of ornaments or supplementaries to edifice but as a main subject of architectural effect. The application of artworks in architectural design, such as paintings or sculptures including installation art possesses social and historical functions as well as contextual meaning. In Korea the interest of environment artworks has increased since early 1980s, during which large projects began to establish. However environment artworks have been selected merely by the owner's preference or the artist's aesthetic value without collaboration with architects or interior architects, who are willing to allow the minimal units of signification to architectural space. The purpose of the study is to prove the importance of environment artworks in spatial design of architecture. The essence intrinsic to design issue will be defined by proposing the selection factors for environment artworks to escalate the value of architectural space, so that we can expect not only the unification of art and architecture but also the accordance between artistry and publicity.

In the Chosun Dynasty (1392-1910), the walls and chimneys of palaces, temples, and the houses of the upper-class show various characteristics of decorative design patterns. This study investigated ceramic bricks and roof tiles, which is one aspect of environmental design studies. This study aimed to provide a typology ot traditional Korean design of bricks and roof tiles used in walls and chimneys, and to show the design characteristics. This study collected 685 designs of bricks and roof tiles, and divided them into 18 categories and 5 types of design patterns based on object figures, architectural styles, materials, and decorative methods. In conclusion, there were differences and similarities among the design patterns. In general, the palaces mostly used red, gray, and black bricks that had more detailed designs presenting auspicious signs or exorcism. But, temples and the houses usually used (black) roof tiles horizontally configured with the edges overlapping to decorate as wall as to strengthen their structure.
