This qualitative case study examined what type of clothing image middle aged housewives strive for, and how to classify the preferred clothing style. Secondly, we examined how their clothing image corresponded to age and observed the meaning of such changes over time. The participants of this study were eight middle aged housewives. This study was conducted through in-depth interviews that were based on an unstructured questionnaire, and the data were collected from January to October 2010. The results were as follows: First, result related to preferred clothing image implicated fashion, esthetic sense, and clothing concerns. Preferred clothing image fell into 'intelligent-colorful' and 'urban-neat' categories. The preferred clothing style types of the participants were labeled as 'trendy', 'classic', 'conservative', and 'unique'. Second, the clothing image that participants thought to be of greater value in middle age included 'graceful' and 'elegant' allowing for the expression of age-appropriate style, high quality, and mind of plenty.

본 연구는 KOMPSAT 광학영상을 이용하여 광범위지역에 대한 도시개발 변화를 탐지하는 방법론을 제시한다. 다른 시기에 취득된 KOMPSAT 영상 간의 방사적인 불일치를 최소화하기 위해서, 본 연구에서는 광범위지역에 대한 변화탐지에 적합한 영역별 간이 방사보정을 전처리과정으로 적용하였다. 도시개발에 대한 변화탐지 결과정확도를 향상시키기 위해서, 환경부에서 제공하는 중분류 토지피복도를 이용하여 수계, 산림과 같은 비관심지역을 제거하였다. 대표적인 변화탐지 기법인 분광변화벡터분석(Change Vector Analysis, CVA) 기법을 적용하여 도시개발에 의해 발생한 변화를 탐지하였다. 제안 기법에 대한 적용을 위해 세종시를 연구지역으로 선정하였으며, 2007년 5월과 2016년 5월에 KOMPSAT-2호로 취득한 영상과 2014년 3월에 KOMPSAT-3호로 취득한 영상을 조합하여 총 세 실험지역을 구축하였다. 2007년 5월 KOMPSAT-2호 영상과 2014년 3월 KOMPSAT-3호 영상으로 구성된 실험지역에 대한 변화탐지 정확도 평가를 수행한 결과, 약 91.00%의 변화탐지 전체정확도를 보였다. 본 연구를 통해 넓은 지역에 대량으로 발생한 도시개발 변화를 효과적으로 탐지할 수 있음을 확인하였다.

Urban transit administers need to introduce the intelligent system to know the situations in the urban transit service area automatically. It is one of the important elements to detect of intrusion in operation room or electric rooms, etc. In this paper, we describe the definition for detection of intrusion in urban transit area, and propose the context-awareness model detect of intrusion. We expect that the definition is helpful to extract the elements that are need to construct the intrusion detecting system. The proposed model that is based on an image analysis model and a rule-based model is also helpful to design intelligent surveillance model.

This paper proposes a method to segment urban scenes semantically based on location prior information. Since major scene elements in urban environments such as roads, buildings, and vehicles are often located at specific locations, using the location prior information of these elements can improve the segmentation performance. The location priors are defined in special 2D coordinates, referred to as road-normal coordinates, which are perpendicular to the orientation of the road. With the help of depth information to each element, all the possible pixels in the image are projected into these coordinates and the learned prior information is applied to those pixels. The proposed location prior can be modeled by defining a unary potential of a conditional random field (CRF) as a sum of two sub-potentials: an appearance feature-based potential and a location potential. The proposed method was validated using publicly available KITTI dataset, which has urban images and corresponding 3D depth measurements.

The domestic Remote Sensing field uses mainly Landsat TM image that is used to the monitoring of the wide area. In this study, it is analyzed the land cover change of rural and urban area by time series using satellite images and is proposed the vision for a urban balanced development. It execute an analysis for urban change which is a fundamental data of city planning through the integration of the spatial analysis technique of GIS and Remote Sensing using satellite data

Airborne laser scanning thechnology has been studied in many applications, DSM(Digital Surface Model) development, building extraction, 3D virtual city modeling. In this paper, we will evaluate the possibility of airborne laser scanning technology for transportation application, especially for recognizing moving vehicles on road. First, we initially segment the region of roads from all LiDAR DATA using the GIS map and intensity image. Secondly, the segmented region is divided into the roads and vehicles using the height threshold value of local based window. Finally, the vehicles will be classified into the several types of vehicles by MDC(Minimum Distance Classification) method using the vehicle's geometry information, height, length, width, etc

A traditional Korean housing is a typical type which is contained life style, spatial organization and scape element of people who lived in Korea. In the hanok, people want to be live not only in human environment and traditional culture, but also modem urban housing as a high density. This article deals as follows: First, Hanok as urban housing would be composed in a housing lot, linear type layout, devide building, and cluster type. Second, Housing unit and configuration of Multi family housing can be used single story, second story, second story + single story, multi story and Hanok roofing. Thirds, structure of the building are traditional wooden, combined one of steel and wood or concrete and wood, and the building system in exterior and interior can be seperated into another system. Forth, Image of multi story Hanok A last, consistency of Hanok is not a repeat of an origin but application and creative aptitude of the origin, and multi family housing application of Hanok can be a trial creative.

The increasing integration of public space and consumerism in Hong Kong has yielded new urban forms. The emergent vertical malls in Hong Kong and other East Asian metropolises have overturned the existing vertical order of the city. This vertical order is determined by the level of accessibility, but is being challenged by widely adopted vertical circulation technology. Inspired by Fredric Jameson's and Rem Koolhaas' reflections on the cultural significance of vertical transportation, this article examines the conflict between market logic and urban design requirements in the vertical interior spaces. "Departmentalization," as the current programming formula for vertical malls, can be further optimized by critically applying urban design doctrines such as Kevin Lynch's five elements of city image. It concludes with a statement that the knowledge base of vertical urbanism should be open to a set of new terminology informed by a new technological environment.

Deep learning models, which imitate the function of human brain, have drawn attention from many engineering fields (mechanical, agricultural, and computer engineering etc). The major advantages of deep learning in engineering fields can be summarized by objects detection, classification, and time-series prediction. As well, it has been applied into environmental science and engineering fields. Here, we compiled our previous attempts to apply deep learning models in water-environment field and presented the future opportunities.
