In order to understand the variation of air quality and the concentration of atmospheric particulates in Chengdu Second Ring Road renovation project, this paper starts to investigate the surrounding residents' opinions on the influenced environment and their daily lives via questionnaires. Then the study numerically simulates the change rule of atmospheric particulates in terms of time and space by using the Gaussian dispersion-deposition model and the compartment model. The optimized scientific scheme is selected by the improved fuzzy analytical hierarchy process(FAHP) to help decision making for the future urban reconstructions. Finally, the reduced emissions of atmospheric particulates are measured when the improvement scheme is provided. According to the study, it can be concluded that the concentration of atmospheric particulates increases rapidly in central Chengdu city during the renovation project, which results in worsening air quality in Chengdu during March 2012 to March 2013. Taking related measures on energy saving and emission reduction can effectively reduce the concentration of atmospheric particulates and promote economic, environmental and social coordination.

Architecture is the historical record of a society. Residential culture is one of the cultures, and includes all the living and customs of people living in the current society. In particular, the Native residence has the research value of changing the living culture because it contains the lives of farmers. The residential culture of the Korean-chinese people contains the poor, agricultural, and immigrant life that began as a livelihood. Therefore, residential culture is an important part of the Korean-chinese culture. However, due to population movement and urbanization, the deepening and aging of the rural community caused the destruction of the residential culture, and the residentials that had been vacant for many years were destroyed, and a large number of risky residential reconstructions are underway. At the point of progress from a voluntary personal building culture to a public building culture built by the government, a study on Renovation of dilapidated Building and a more reasonable residential reform plan is needed. Our housing culture should not only improve the living environment of current life, but also inherit the housing culture contained in history.

This study was carried out to investigate the effects of herbicide treatment and seeding method on the forage yield, weed control, and persistency in the Artemisia princeps dominated pasture. It was arranged as a randomized block design with seven treatments(\circled1 oversowing(control),\circled2 glyphosate 4 ${\ell}$/ha + oveysowing a \circled3glyphosate 4 ${\ell}$/ha + chiselreseeding, \circled4 paraquat dichloride 3 ${\ell}$/ha + oversowing,\circled5 paraquat dichloride 3 ${\ell}$/ha + chiselreseeding, \circled6 dicamba 4 ${\ell}$/ha + oversowing and \circled7 dicamba 4 ${\ell}$/ha + chiselreseeding), and conducted at National Livestock Research Institute in Suwon from June, 1985 to October, 1987. In the Artemisia princeps dominated pasture, the treatments of glyphosate 4 ${\ell}$/ha before oversowipg or chisel reseeding controlled 80.7-83.3% of the Artemisia princeps, and for two years the average dry weight of Artemisiaprinceps greatly decreased, but dry matter(DM) yield of forage increased 57-96% than that pf control. In the herbicide treatments, the average DM yield of forage in the plots with chisel r e d i n g was significantly higher when compared to oversowing. The results in this study indicated that herbicide treatment was effective for the control of Artemisiaprinceps, and good renovation of grassland and higher DM yield of forage could be obtained by application of glyphosate.

Elementary school classroom designs have been developed toward open education system to provide students diverse and improved educational environments since the early of 1990 in Korea. Unfortunately, the quality of music room has not still shown dramatic improvements due to the lack of the acoustical knowledges of architects. This report aims to investigate typical acoustic quality of previous or current music room of elementary schools and show new acoustic treatment technologies to improve the room acoustic of music room by adapting composite perforated panel system and diffusion technology. The music room at Daihyun Elementary school in Yongin was chosen as a case study of this report. The music room was measured to be analyzed using field measurements and the acoustical specifications of composite perforated panel systems and kinds of diffusors were set. Acoustic measurements were performed after the renovation to show the differences between previous room acoustic and after the acoustic renovations. As the result, the case study has shown that the new composite perforated panel systems and diffusion surfaces lowered reverberation time at proper level along with improving the clarity of music, RASTI, and spatial impressions. Also, acoustic interferences such as comb filtering and flutter echoes have been controlled dramatically by diffusive surfaces. The study shows music rooms in elementary schools, middle and high schools can be improved by adapting composite perforated panel systems and diffusors.

The purposes of this study were to provide information on customers for cosmetic companies to develop goods and promotion strategy by examining facial images of university women and their recognition level about cosmetics brand personality. The results were as follows; First, satisfaction level of university women with their lips and eyes was very high, while lowest in skins. Second, factors of brand personality of three kinds of foreign cosmetics brands and three kinds of domestic brands were sincerity, beauty, renovation, reliability and ruggedness. In beauty, reliability and ruggedness, they preferred foreign brands to domestic ones, while they preferred domestic ones in sincerity and renovation. Third, the satisfaction level with face had a statistically significant relationship to the importance of face and cosmetic brands, while the importance of face had to the beauty of the brand. In the interrelationship among facial images and the factors of brand personality, they had significant interrelationships, provided beauty and ruggedness, and reliability and ruggedness had no significant interrelationship.

This design proposal was presented to a design competition for renovation of the Pagoda Park, located in Chongro-2ga, Chongro-gu, Seoul, where the first ˝Manse˝ (hurrah) Movement fighting against Japanese colonization, broke out on March 1st, 1919. The park has been considered to be the first modern park in Korea also. The objectives for the design were to make a sacred place to commemorate the 3.1 ˝Manse˝ Movement, to preserve and symbolically memorialize historic remains of the old ˝Wongaksa˝ Temple, an to provide natural and rest areas for citizen. For the space composition, three axes symbolic of, ´freedom and independence´, ´mercy´, and ´nature´, were created. For the freedom and independence axis, exiting facilities, such as statures and monuments related to the 3.1 Movement, were relocated centering around the octagonal pavilion, which was the starting point for the movement, to give order of the site. For the ercy axis, symbols of traditional temple structures, such as, ´Iljugate´-´Pian bridge´-´Chongwang gate´-´Haetal gate´-Pagoda-Buddhist sanctum, were created to symbolize the temple remains and placeness. For the nature axis, tree groves, walking trails, and rest areas for citizen were provided around the site. As a whole the design provided structural orders from secular spaces outside to sacred spaces inside.

This study aims to find the conservation and regeneration plan in terms of preserving and utilizing old wooden houses, regenerating existing buildings, and developing idle land for old dwellings located outside the southern gate of Cheongju, Korea. In the preservation and utilization of old houses, three places in the block where wooden houses clustered are created as conservation houses, and are conversed as cafes, workspaces, and homestays along with the preservation of individual houses. In the regeneration of existing buildings, the street landscape was improved through extension and renovation, new construction after demolition, and exterior renovation for one or two-story buildings facing the roadside. In the development of idle land, it reflects the layout method and open yard space corresponding to the path and orientation of the old house, and the mass was varied and segmented to resolve the medium scale. Accordingly, considering the context, landscape, and environmental aspects of the historical downtown, the development of old dwellings in downtown should shift from a uniform high-rise apartment project-oriented approach to a gradual and continuous regeneration direction.
