The service that has recently come into the spotlight utilizes the map to first approach the map and then provide various mash-up formed results through the interface. This service can provide precise information to the users but the map is barely reusable. The sketch-map system of this paper, unlike the existing large map system, uses the method of presenting the specific spot and route in XML document and then clustering among sketch-maps. The map service system is designed to show the optimum route to the destination in a simple outline map. It is done by renovating the spot presented by the map into optimum contents. This service system, through the process of analyzing, splitting and clustering of the sketch-map's XML document input, creates a valid form of a sketch-map. It uses the LCS(Longest Common Subsequence) algorithm for splitting and merging sketch-map in the process of query. In addition, the simulation of this system's expected effects is provided. It shows how the maps that share information and knowledge assemble to form a large map and thus presents the system's ability and role as a new research portal.

The purpose of this study is to examine and better understand student's perception of territory in the deterritorialized world. Students' sketch maps were analyzed to investigate the way of which they recognized the form of national territory, border, geographic location, and neighboring countries. In addition, students' values, attitudes, and affection for their homeland and other countries were observed through the awareness of North Korea, DMZ, and Dok-do island. Scrutinizing students' sketch maps and follow-up interviews provided much more in-depth context for understanding students' narratives about territorial identity than did the analysis of structured surveys since they can freely draw and sketch their cognition. A qualitative data analysis builded a code list with 67 codes generated from 626 quotations. These data were exported to CSV format to elicit and evaluate differential variances of territorial identity along with student's Social Studies score and Grade Point Average for inferential statistics and quantitative data analysis using SPSS. Based on the results of data analysis and discussion, some suggestions to build a model of territorial education and to develop teaching and learning materials in the domain of geography education were provided.

Recently, one of the received attraction fields in web based service is 'Human Relationship Service' that is called SNS. This relationship map service is able to deliver information to user more easily and visually because it is intuitive data that is linked with offline real world. While past map service put physical real information in the map, present map service is evolving into new communicative platform that expresses social relationship beyond simple search platform that shows real world. In this paper, we propose smart social grid system using sketch map that is based on online map service structure. This system has features such as standardized interface provision for various SNS, use to governance hub tool in case of establishing a personal network through expanded social grid, a role of bridge to mashup software linked with other SNS, user environment construction that reproduces social grid data, and the faster service setup by improved search technology.

본 논문에서는 타블렛을 이용해 사용자로부터 주름 스케치를 입력받아 피부 패턴을 고려한 사실적인 얼굴 주름을 생성 할 수 있는 인터페이스를 제안한다. 주름을 생성하고 싶은 모델의 normal map에 간단한 스케치를 하면 해당 모델의 피부 패턴을 고려해 스케치를 주름으로 생성해준다. 또한, 얼굴 부위별 주름 형태를 분석하여 부위별 생성되는 주름의 형태가 다르고, 나이 설정을 통해 나이에 맞는 잔주름 및 주름 형태를 변형 한다. 본 논문에서 제안하는 방법을 이용한 주름 생성 방식은 주름에 대한 자세한 지식이 없는 사용자라도 간단한 스케치만 한다면 자동 계산을 통해 실시간으로 주름을 생성해주며, 얼굴 패턴에 따른 사실적인 주름이 생성되는 결과를 보여준다.

디자인 프로세스상에 이미지를 중심으로 하는 시각언어를 통한 디자인 컨셉 커뮤니케이션은 이미 여러 디자인분야에서 여러 가지 방향으로 진행되고 있다(스타일 스케치보드, 이미지 맵, 컬러맵, 캐털로그 리뷰 등). 그러나 대부분의 경우, 디자인 리서치에 사용되어진 이미지들은 리서치 이후 저장되지 않고 폐기되어지기 때문에, 새로운 디자인 작업에서 재활용되어지지 못하는 프로세스상의 단점을 가지고 있다.(중략)

When rendering both three-dimensional objects and photo images together, the non-photorealistic rendering results are in visual discord since the two contents have their own independent color distributions. This paper proposes a non-photorealistic rendering technique which renders both three-dimensional objects and photo images such as cartoons and sketches. The proposed technique computes the color distribution property of the photo images and reduces the number of colors of both photo images and 3D objects. NPR is performed based on the reduced colormaps and edge features. To enhance the natural scene presentation, the image region segmentation process is preferred when extracting and applying colormaps. However, the image segmentation technique needs a lot of computational operations. It takes a long time for non-photorealistic rendering for large size frames. To speed up the time-consuming segmentation procedure, we use GPGPU for the parallel computing using the GPU. As a result, we significantly improve the execution speed of the algorithm.

Chinese ethnic minorities are inheriting their own traditions based on thousands of years of community life. Yunnan province in china is a castle in which many ethnic minorities have been living on the basis of various natural environments. Their traditional village can be regarded as a place reflecting minorities' thousands year of history and culture, and elements of positive social spaces are seen from the old village. Streets and places of the village are accumulated as images for residents. Based on their imagination-concept, sketch maps, reflecting residents' cognitive perception were collected. Analysis of 21 sketch maps shows that architectural elements, forming a unique landscape and community life contribute to establish a unity of one nation. the oldest tree in the village has a strong specificity as a place with the belief that the tree protects all residents in the village. Space in the head of the residents and Social spaces, embedded in the memories of the residents living in the community continued organically and the roads of the village showed clear recognition. Following this, the analysis methodology of social spaces and sketch will be examined in depth.

Smart-textronics technology which enables functional textiles has recently been applied in various fields such as smart clothes, smart home and smart health care, and a variety of smart-textronics products have been developed. In this context, the smart-textronics product development process is proposed based on the systematic participatory design method in this paper. The proposed method consists of two phases: in-depth interviews and analyzing. In the phase of in-depth interviews, participants are asked to create journey maps that include activities, pain points and emotional status and to generate solution ideas with sketches and simple prototypes. In the analyzing phase, design researchers investigate the participants' journey maps, and create personas by identifying critical characteristics with the behavior pattern analysis. Then, each persona's needs are linked with value elements of the E3 value framework. Finally, pre-survey was conducted to identify smart-textronics market and a smart sofa design is proceeded as the case study to show the applicability of the proposed method.

For old-age makeups, makeup artists first make a mold cast of an actor's face using plaster and then sculpt wrinkles in clay on the plaster mold. After finishing the clay sculpture, its negative plaster mold is fabricated and silicone skin patches are finally made for application to the actor's face. This process takes a few days and is tedious for actors and makeup artists. With recent advances in 3D printing and scanning technology, it is becoming easier to scan and fabricate 3D faces. This paper presents a new pipeline composed of facial scanning, interactive wrinkle modeling, and mold printing stages to easily and efficiently fabricate silicone masks for old-age makeups without the use of plaster and clay. An intuitive sketch interface based on a normal map is proposed for the creation of wrinkles in real time, even with a high-resolution face model. Then the geometry of the final wrinkles is reconstructed using a depth map and the negative mold of the wrinkled face is printed. We also show that the presented pipeline can fabricate a silicone mask more conveniently than the traditional one that consists of pouring silicone into the prepared negative mold and then overlapping the mold with the original positive one.
