A coastline is the boundary between land and ocean masses. Knowledge of coastline is essential for autonomous navigation, geographical exploration, coastal erosion monitoring and modelling, water line change, etc. Many methods have been researched to extract coastlines from the synthetic aperture radar (SAR) and optic images. Most methods were based on the intensity contrast between land and sea regions. However, in these methods, a coastline detection task was very difficult because of insufficient intensity contrast and the ambiguity in distinguishing coastline from other object line. In this paper, we propose an efficient method for the delineation of coastline using interferometric coherence values estimated from ERS tandem pair. The proposed method uses the facts that a tandem pair of ERS is acquired from a time interval of an accurate day and that the coherent and incoherent values in coherence map are land and water, respectively. The coherence map was generated from ERS tandem pair, filtered by MAP filter, and divided into land and water by the determination of threshold value that is based on the bimodality of the histogram. Finally, a coastline was detected by delineating the boundary pixels. There was a good visual match between the detected coastline and the manually contoured line. The interferometric coherence map will be helpful to identify land and water regions easily, and can be used to many applications that are related with a coastline.

인간이 어떤 것에 대하여 경험을 할 때에, 그 경험은 지식이라고 하는 형식으로 뇌에 보존됨과 동시에, 상황에 따라서는 직관적인 판단을 위한 정보로서 역할을 수행한다. 이러한 관점에서 본 연구에서는, 디자인 컨셉 작성에 필요한 여러 가지 요소에 대하여 직관적인 판단을 하고, 시각적인 컨셉을 작성했을 때, 그것이 아이디어 발상에 미치는 영향의 특징을 분석하는 것을 목적으로 하였다. 실험은 두 가지 단계로 진행하였다. 첫 번째는, '새로운 디지털 카메라의 디자인'이라는 과제 수행을 위하여, 디지털 카메라의 12가지 구성 요소의 관계를 직관적으로 판단하여 일정한 공간에 배치하도록 하였다. 그 다음, 배치된 각 구성요소의 관계를 고려하여 아이디어 스케치를 진행하도록 하였다. 실험 결과, 직관적인 판단에 의해서 시각화된 컨셉은, 구조적인 사고, 다양한 형태의 전개, 구체적인 조작 방법의 제안, 그리고 자신의 스케치를 설명하기 쉽게 표현하는 것에 많은 영향을 미치는 것이 확인되었다. 그러나, 인간의 자유로운 감성적인 발상은, 조건의 제약에 의한 구조화가 아닌 것도 알 수 있었다.

As the computer becomes a trend, interactive multimedia design can be one media to communicate the cultural knowledge. A folktale can be a powerful material to show a country's culture. In this project, we try to make the folktale content to be understood easily by implementing some cultural information background. The main aim of this project is to give a vision of the richness culture through the interactive multimedia technology. In this paper, we would like to show a flow map content, a streaming of design process and a visual interface design prototype. Finally, interactive multimedia design content is very useful for a transferring the richness culture because people tend to like a multimedia content. In order to make an effective interactive multimedia design content based on a cultural background, a designer should need to understand about users, culture, technology and the whole design process.

Analyzing textbook is the first step for enhancing the level of biology education especially in Korea. Prior studies of textbook analysis have mostly dealt with such topics as terminology analysis, content analysis, relationship analysis of chapters, and comparative studies. However, not much attention was paid to concept system to be learned and to relevance of concepts chosen. Therefore, the purpose of this study is to clarify the concept system and to elucidate the relationship among concepts for effective learning. Novak's concept map was utilized as a theoretical framework for the analysis of chapter I of high school biology textbook. Concept map has several distinctive merits in many aspects such as teaching, learning, and evaluation. It not only makes the understanding of key concepts and proposition a lot easier, but also helps to link prior knowledge and new concepts more effectively. This study will be a basic material for improving textbook for effective biology learning. The conclusions of the study are as follows: 1. Concepts in subchapters were arranged unsystematically or they were overlapping. For more effective understanding, those items should be rearranged. 2. Key concepts are not arrayed properly according to their hierarchy. Therefore, it was hard for students to set up concept structure. 3. The concepts emphasized by bold letters were not selected properly in accordance with their importance. Appropriate concepts should be chosen. 4. Key concepts should be explained by using examples in everyday life for easy understanding. 5. Many concepts in molecular biology is too abstract to grasp their meaning. Therefore, many audio-visual materials should be used to aid concept building.

We propose an effective deep learning model to denoise scanning transmission electron microscopy (STEM) image series, named Noise2Atom, to map images from a source domain 𝓢 to a target domain 𝓒, where 𝓢 is for our noisy experimental dataset, and 𝓒 is for the desired clear atomic images. Noise2Atom uses two external networks to apply additional constraints from the domain knowledge. This model requires no signal prior, no noise model estimation, and no paired training images. The only assumption is that the inputs are acquired with identical experimental configurations. To evaluate the restoration performance of our model, as it is impossible to obtain ground truth for our experimental dataset, we propose consecutive structural similarity (CSS) for image quality assessment, based on the fact that the structures remain much the same as the previous frame(s) within small scan intervals. We demonstrate the superiority of our model by providing evaluation in terms of CSS and visual quality on different experimental datasets.

Capriccio which has emersed in Italy of the 18th century is a new genre of the landscape painting. This genre represents reality, but it is very artificial product correspondingly its concept and character. It's birth place is distributed on various regions in Italy, but the main stage was Rome. Till the middle of the 18th century Rome was the Holy city of the Grand tour, the home of the Neo-Classicism and furthermore the field where archaeology and art history began to be instituted. On such historical situation the Capriccio came out and was recognized as the best popular genre in the visual art. It was favor of the art collection with the antiquity together and reflected the consciousness of the contemporary to the ancient. This study will examine the phenomena in the newly-developed archaeology and with few representative works of Giovanni Paolo Pannini as central term consider the Capriccio and the archaeological connotation. The systematical and institutional archeology which appeared at the age of the Enlightenment, on the contrary to the critical theories at the same time against capriccio, because it was regarded by them as paradoxical and too much sensitive, utilized it as a theoretical method very actively. Some among Historians and archaeologists did it, especially Francesco Bianchini distinguished the capriccio from simple imagination and made it a capacity of the knowledge. And through it he wanted to find out the historical truth. The visual art was influenced and encouraged by such attitude of the archaeology. However it's output spreaded out in various courses. While Giovanni Battista Piranesi, the best known Capriccist of the 18th century, tried to revive the antique through the epical value and his own imagination, Pannini gave priority to the strict historical research. In the such context Panni succeed Giovanni Battista Nolli who made the great map of the city Rome. Their Capriccio profited motive and was inspired by the historians and archaeologists such as Bianchini and Muratori. The Capriccio reflects not only the academic and popular interest for the antique, but also influenced on the upcoming scientific archaeology vice versa. It caused by their reasonable Interpretation and restoration of the antique through the visual medium. Finally as archaeological landscape Pannini's Capriccio is a historical case, in that the Capriccio applied the theoretical method of the archaeology to make art. It served as a momentum for the connotation to the archaeological thought.

Background: Cholangiocarcinoma (CCA) is a serious public health problem in the Northeast of Thailand. CCA is considered to be an incurable and rapidly lethal disease. Knowledge of the distribution of CCA patients is necessary for management strategies. Objectives: This study aimed to utilize the Geographic Information System and Google $Earth^{TM}$ for distribution mapping of cholangiocarcinoma in Satuek District, Buriram, Thailand, during a 5-year period (2008-2012). Materials and Methods: In this retrospective study data were collected and reviewed from the OPD cards, definitive cases of CCA were patients who were treated in Satuek hospital and were diagnosed with CCA or ICD-10 code C22.1. CCA cases were used to analyze and calculate with ArcGIS 9.2, all of data were imported into Google Earth using the online web page www.earthpoint.us. Data were displayed at village points. Results: A total of 53 cases were diagnosed and identified as CCA. The incidence was 53.57 per 100,000 population (65.5 for males and 30.8 for females) and the majority of CCA cases were in stages IV and IIA. The average age was 67 years old. The highest attack rate was observed in Thung Wang sub-district (161.4 per 100,000 population). The map display at village points for CCA patients based on Google Earth gave a clear visual deistribution. Conclusions: CCA is still a major problem in Satuek district, Buriram province of Thailand. The Google Earth production process is very simple and easy to learn. It is suitable for the use in further development of CCA management strategies.

커뮤니케이션 이론에서는 지도의 역할을 단지 커뮤니케이션 도구로 한정시켜 지도의 기능성을 지나치게 강조한 나머지, 컴퓨터, GIS, 과학적 시각화(scientific visualization) 등과 같은 새로운 지도학 환경에서 요구되는 새로운 역할을 성공적으로 수행할 수 없었다. 그 결과 커뮤니케이션 이론에 대한 반론과 함께 새로운 대안들이 등장하게 되었다. 지도학의 새로운 대안을 세 가지로 정리하면 다음과 같다. 첫째, 지리적 시각화로 지도란 분석된 결과만을 전달하는 도구가 아니라 분석의 이전 단계인 자료의 검색, 가설의 설정, 자료의 분석에 이르기까지 다양하게 이용될 수 있다는 견해이다. 둘째, 지도의 기능성에 대한 관심 증대로 인해 지도화 과정에서 예술성 및 총체성이 무시된다는 점이다. 지도란 단지 개별 정보의 전달 도구라기보다는 공간에 대한 총체적인 상이며, 다양한 수준에서 여러 가지 의미를 내포하고 있기 때문에 지도의 예술성이 강조되어야 한다. 셋째, 과학적이고도 객관적인 법칙이나 지침에 따라 만들었다는 지도 역시 지도에 내재된 주관성과 수사적 내용을 피할 수 없다는 점이다. 따라서 해체주의적 관점에서 지도학을 구조화한 사회적 힘을 찾아 힘의 존재와 그것의 영향을 모든 지도학 지식에 접목시키려는 것이다. 최근 과학적 시각화를 위한 도구로서 지도의 기능이 새로이 강조되면서, 지리적 시각화라는 새로운 개념이 대두되었다. 컴퓨터 그래픽을 기본 도구로 사용하여, 패턴, 관계, 특이 현상 등을 확인하여 새로운 과학적 시각을 얻고, 새로운 시각에서 문제를 재구성하는 것이 지리적 시각화의 목적이다. 따라서 기존의 지식을 표현하기 위한 시스템은 현재의 한계를 뛰어 넘으려는 첨단과학자에게 필요한 도구를 제공해 줄 수 없기 때문에, 지리적 시각화를 위한 새로운 도구가 개발되어야 한다. 한편 지리적 시각화는 지도학의 새로운 관점이 아니라, 어쩌면 커뮤니케이션 이론의 도입으로 서로 다른 길을 걸어 왔던 지도학자와 지리학자들이 지리적 시각화를 통해 두 학문간의 연계를 재정립하는 '지리적' 지도학 혹은 분석지도학을 부활시키는 계기가 마련될 수 있다.
