Since the mitigation of fear of crime significantly enhances the consumptions in a city, studies focusing on urban safety analysis have received much attention as means of revitalizing the local economy. In addition, with the development of computer vision and machine learning technologies, efficient and automated analysis methods have been developed. Previous studies have used global features to predict the safety of cities, yet this method has limited ability in accurately predicting abstract information such as safety assessments. Therefore we used a Convolutional Context Neural Network (CCNN) that considered "context" as a decision criterion to accurately predict safety of cities. CCNN model is constructed by combining a stacked auto encoder with a fully connected network to find the context and use it in the CNN model to predict the score. We analyzed the RMSE and correlation of SVR, Alexnet, and Sharing models to compare with the performance of CCNN model. Our results indicate that our model has much better RMSE and Pearson/Spearman correlation coefficient.

A new method is developed to estimate road profile in order to estimate IRI based on the ASTM standard. This method utilizes an accelerometer and a Dynamic Tire Pressure Sensor (DTPS) to estimate road roughness. The accelerometer measures the vertical axle acceleration. The DTPS, which is mounted on the tire's valve stem, measures dynamic pressure inside the tire while driving. Calibrated transfer functions are used to estimate road profile using the signals from the two sensors. A field test was conducted on roads with different quality conditions in the city of Brockton, MA. The IRI values estimated with this new method match the actual road conditions measured with Pavement Condition Index (PCI) based on the ASTM standard, images taken from an onboard camera and passengers' perceptions. IRI has negative correlation with PCI in general since they have overlapping features. Compared to the current method of IRI measurement, the advantage of this method is that a) the cost is reduced; b) more space is saved; c) more time is saved; and d) mounting the two sensors are universally compatible to most cars and vans. Therefore, this method has the potential to provide continuous and global monitoring the health of roadways.

The purpose of this study was to find common characteristics in everyday landscape cognition that the residents share and to restore the resulting characteristics through citizen-participatory town design. Through the residents participatory workshop supported by the Gwangju Buk-gu District Autonomy and Citizen Academy of Gwangju YMCA, 304 people from eight administrative districts participated in three programs. In each program, photographed landscape images representing everyday conditions of the townscape were presented in several ways: in program 1, the residents' mental map was studied; in program 2, landscape images of real places were matched to locations on a map; and in program 3, the landscapes were scored on a scale from 1 to 5 according to five descriptive categories. The elements that were recognized as common landscape features were public facilities, pedestrian spaces, school areas, and parks and natural green spaces. Additional results including recognition of the participants affection for the village and a common landscape image shared by the people, as inhabitants looked around at the space of their own lives. It seems possible that more creative townscapes can be created by residents through participatory programs.

The alkali granite occurred as small stock and dyke is distributed in the Kyeomyeongsan Formation in the vicinity of the Chungju city. Geochemical characteristics in major and trace element of alkali granite in the Kyeomyeongsan Formation indicate that the alkali granites are peralkaline and have similar geochemical features to the A-type alkali granite. The rock enriched in HFSE such as Zr, Nb, Y, REE etc. According to the discrimination diagram the alkali granites mostly belong to the within-plate granite field, and to the $A_1$ group of A-type granite. This suggests that they might be emplaced in a extentional rift environment. The alkali granites are characterized by remarkably high total REE content, and enriched, relatively flat to somewhat HREE-depleted patterns with large negative Eu anomaly. The Sm-Nd age of the alkali granite is $338{\pm}30Ma$ with ${\varepsilon}_{Nd(t)}$ beings -7.3 to -8.5. On the basis of the geochemical studies the source magma was derived from a enriched mantle-like source and had a few or clearly interaction with sialic continental crust. In conclusion, the alkali granitic rock of the Kyeomyeongsan Formation might be formed from the high F peralkaline magma that was emplaced in continental rift environment, and generated at the early Carboniferous.

Since Seoul city supplied 'Sangsang Children's Playground', domestic playgrounds are changing from formal facilities to creative play and learning space recently. From eco-friendly safe playground model development project, eco-friendly playground planning and its actual cases have been occasionally introduced. However, we could not know how well most playgrounds reflect eco-friendly features and whether they are eco-friendly or not because the definition about the concept of eco-friendly playground is inadequate and there are not the specific planning guidelines and evaluation standards for making the eco-friendly playground. Therefore, the development of guidelines for the construction of eco-friendly playground is required and evaluation guidelines for them should be made for the active dissemination of the actual eco-friendly playground and the proper construction of the eco-friendly playground. In this study, we defined the concept of eco-friendly outdoor playground and presented the types and characteristics of the playground based on the concept and suggested basic plan guidelines based on the existing requirements for becoming eco-friendly playground. For this purpose, we checked the plan's common points in the existing playground configuration requirements, installation standards, regulations, and safety standards, and offered the planning elements and guidelines through the analysis of outdoor space evaluation standard in eco-friendly safe playground guidelines and eco-friendly building certification system.

Based on the reconnaissance of buildings in Dujiangyan City during 2008 Wenchuan earthquake, China, structural damage characteristics and the spatial distribution of structural damage are investigated, and the possible reasons for the extraordinary features are discussed with consideration of the influence of urban historical evolution and spatial variation of earthquake motions. Firstly, the urban plan and typical characteristics of structural seismic damage are briefly presented and summarized. Spatial distribution of structural damage is then comparatively analyzed by classifying all surveyed buildings in accordance with different construction age, considering the influence of seismic design code on urban buildings. Finally, the influences of evolution of seismic design code, topographic condition, local site and distance from fault rupture on spatial distribution of structural damage are comprehensively discussed. It is concluded that spatial variation of earthquake motions, resulting from topography, local site effect and fault rupture, are very important factor leading to the extraordinary spatial distribution of building damage except the evolution of seismic design codes. It is necessary that the spatial distribution of earthquake motions should be considered in seismic design of structures located in complicated topography area and near active faults.
