Biochar amendment to agricultural soil is regarded as a promising option to mitigate climate change and enhance soil quality. It could sequester more carbon within the soil system and increase plant yield by changing soil physicochemical characteristics. However, sustainable use of biochar requires comprehensive environmental assessment. In this sense, it is important to measure additional greenhouse gas emission from soils after biochar addition. We investigated emissions of CO2, N2O, and CH4 from incubated soils collected from rice paddy and cultivated grassland after amendment of 3% biochar (wt.) produced from rice chaff. During incubation, soils were exposed to three wet-dry cycles ranging from 5~85% soil gravimetric water content (WC) to investigate the changes in effect of biochar when influenced by different water levels. The CO2 emission was reduced in biochar treatment compared to the control at WC of 30~70% both in rice paddy and grassland soils. This indicates that biochar could function as a stabilizer for soil organic carbon and it can be effective in carbon sequestration. The N2O emission was also reduced from the grassland soil treated with biochar when WC was greater than 30% because the biochar treated soils had lower denitrification due to better aeration. In the rice paddy soil, biochar addition resulted in decrease in N2O emission when WC was greater than 70%, while an increase was noted when WC was between 30~70%. This increase might be related to the fact that available nutrients on biochar surface stimulated existing nitrifying bacterial community, resulting in higher N2O emission. Overall results imply that biochar amendment to agricultural soil can stabilize soil carbon from fast decomposition although attention should be paid to additional N2O emission when biochar addition is combined with the application of nitrogen fertilizer.

이샘(Lee, Seam),신선하(Shin, Sun-Ha),유예나(Yoo, Ye-Na),안세윤(An, Se-Yun) 한국실내디자인학회 2015 한국실내디자인학회 학술대회논문집 Vol.2015 No.5
There is a growing trend to use tradition elements such as traditional Korean cuisine and culture as major items. in the restaurant industry of large companies. This study aims to investigate the cases of expression method which traditional images are applied to the modern restaurant spaces. We only focus on the authentic Korean food brands among the Korean buffet restaurant franchises which are run from 2013. The designs of restaurant spaces are classified into space elements and sensitive elements to analyze the expression method of the traditional images. The purpose of this study is to show a guideline for the future plans to use traditional images in modern restaurant space and lay the groundwork for making a effective plan in spatial composition. It would broaden the scope of the study to other franchises and commercial space. It is expected that in the study of further research on the traditional image of commercial space have been applied.

우리나라의 범죄발생 현황을 분석하면 생명, 재산과 관련된 흉악범죄의 증가 추이가 두드러진다. 이러한 사회 현황에 대한 경각심과 국민들의 안전욕구 강화에 따라, 정부차원의 다양한 방안이 시도되고 있다. 그러나, 세부적인 환경디자인요소에 대한 구체적인 방안은 미흡한 것이 현실이다. 따라서, 본 연구는 도시의 범죄율이 높은 공간 중 대표적인 공간유형인 폐쇄적인 골목길을 선정하여, 환경디자인 구성요소들의 효용성과 개선방향에 대하여 조사ㆍ분석하여, CPTED 기법의 개선방향을 제시하였다. 1) 문헌을 통해 CPTED의 개요 및 구성 원리에 대해 조사 분석 하고, 2) CPTED기법으로 활용되고 있는 환경요소들을 도출하였다. 3) KJ법을 활용하여, 폐쇄적 공간에서 환경 요소에 대한 CPTED기법의 적정성 여부, 문제점, 개선방향 등을 분석하였다. 4) 최종적으로는, 폐쇄적 공간에 적합한 환경요소를 파악하고, 이에 대하여 CPTED기법을 적용하기 위한 방향을 제시하였다. 분석 결과 크게 2가지로 정리하면 다음과 같다. 1) 폐쇄된 골목길에서 가장 필요로 하는 환경요소는 가로등이며, 실제 CPTED요소로서 이러한 공간에 많이 사용되는 미러거울이나 코너볼록거울은 부정적으로 생각하는 경향이 많은 것으로 나타났다. 이들은 다른 요소와 결합하여 사용하므로, 각각의 단점을 최소화하고 활용도를 높이는 방안으로 강구해야 한다. 2) 기계적 요소 중 CCTV, 위치번호판, SOS비상벨의 색상은 고채도의 색채를 사용하거나 조명과 병행하여 사용하므로 시인성과 유목성을 높이도록 계획하여야 하며, 벽화와 울타리에 대해서는 효과적인 디자인에 대한 고려가 반드시 필요하다. 향후 다양한 특성의 공간에 적합한 환경시설물에 대한 조사와 그에 따른 디자인에 대한 연구가 필요하다. According to the crime statistics in South Korea, the number of serious crime which is related to individual life and property has been increased. Due to the fact that arousing people’s attention to the security issue is not able to overlook so that there are a lot of approaches to deal with alleviating the crime rate by Korea government. However, the specific solution for environmental design factor in detail had not been presented. Accordingly, this research is working on analyzing the usefulness and improvement of the CPTED method in environmental design factor as well as the research method is going to apply to the narrow back streets which are related to the high crime rate. 1) Literature reviews account for the basic knowledge of the CPTED 2) Evaluating environmental factor based on the CPTED method. 3) Analysed possible development, problem, reasonableness of CPTED method in regards to environmental component in closed space by applying KJ method. 4) Finally, analysed appropriate environmental factor for closed space and provided guideline in order to apply the CPTED method. Result can be stated in 2 points as follows, 1) It appears that the most needed environmental factor on a closed alley is a streetlight, while mirrors or corner convex mirrors, the most commonly used CPTED factors in alleys, are perceived negatively. Since these factors are used in combination with others, the solution to diminish weaknesses and enhance efficiency must be considered. 2) Of mechanical factors, CCTV’s, location number plates, and SOS emergency bells have to be in high chroma or utilized with lightings, so they have to be planned to heighten attractiveness of colors and ability to be observed. Effective designs of installation on walls or fences must be considered. Research on environmental equipment appropriate for certain places and research on design accordingly must be accompanied.
