HEC-GeoRAS는 HEC-RAS의 모의값을 토대로 지형공간자료로 나타내기 위한 ArcView GIS의 확장모형이다. 이모형은 홍수 범람도 작성 및 침수피해 위험도 평가 등에 이용되고 있으며, 이때 홍수 범람도 작성이나 침수범위 설정에 이용되는 지형자료가 수치지형모형(DTM)이다. 수치지형모형에서 표고는 수치지도와 횡단자료를 중첩시켜 만든 TIN(Triangulated Irregular Network)과 같은 자료 구조 규칙을 사용하여 저장된다. HEC-GeoRAS에서 여러 가지 RAS Themes을 만드는데 이 중에서 지형속성 Themes을 생성할 때 문제점이 발생하는데 사용자가 HEC-GeoRAS 사용하여 직접 드로잉하기 때문에 잘못된 위치에 지형속성자료를 입력할 수 있다는 것이다. 또한 TIN생성 시 하천 고수호안이 수직 옹벽형태로 되어 있으면 벽체에 여러 개의 고도자료가 존재하는데 한 개의 고도값만 입력할 수 있어 횡단면이 왜곡된다는 점이다. 본 연구에서는 이러한 문제점을 해결하고자 ArcView GIS에서 RAS Themes을 구축할 때 Auto CAD를 사용하여 지형속성자료를 드로잉 하였고, 수직 옹벽형태의 측점을 수정하여 고도값을 추가 입력하였다. 연구 대상지역은 광주천으로 고수호안이 수직 옹벽형태로 되어 있어 벽체에 여러 개의 고도값이 존재하므로 TIN 구축 시 횡단면이 왜곡되는 하천이다. 연구결과 횡단자료가 갖고 있는 좌표를 Auto CAD에서 입력할 수 있어 정확한 위치에 지형속성자료를 생성할 수 있었다. 또한 수직 옹벽형태의 측점을 수정하여 고도값을 추가 입력함으로써 횡단면 왜곡을 보완할 수 있었다. 홍수량에 따른 최대 침수심과 침수면적을 분석한 결과 횡단자료 수정 전 후 2배정도 차이가 생김을 알 수 있었다. 본 연구의 결과를 이용하면 보다 정확한 침수범위를 설정할 수 있고, 저빈도 홍수위 분석도 용이할 것이다.

Dutch artist, Theo van Doesburg had shown short but strong experimental aesthetics in his works through De Stijl movement. He played a leading role for editing De Stijl magazine and performed various formative works such as painting, sculpture, and architecture. In 1923 he opened the first De Stijl exhibition cooperated with Cornelis van Eesteren. In this architecture exhibition he showed rich formal spirits of counter-construction in his major design works, that is Maison Particuliere and Maison D'artiste among three houses projects. Formal characteristics of counter-construction can be summed up under two categories, time and space. Analytical results are as follows; First, the characteristics of counter-construction related to time category include two types of two mode. One is linear aspect of time based on the viewer's movement. The other aspect is simultaneity caused by synoptical effect. These could be proved by the analysis of arrangement of color planes. Secondly, the spatial aspects of counter-construction are produced through two different ways of formal strategies. Van Doesburg arranged cubes in very irregular pattern. This treatment induces ambiguous void and creates feeling of subject's space. And, through deleting, shifting, and extending he could make dynamic spatial effect by interpenetration between in and out. This fluid space thus introduces movements of one's gaze and circulation. He denied traditional classical values which had ruled the western aesthetical discipline for centuries and believed that mankind can reach the realm of universal equilibrium by contrast and tension created by counter-construction. In this vein Theo van Doesburg was an avant-garde artist of Hegelian thoughts who adopted the dialectical method without following the formal characteristics from ancestors.

Recently, the use of digital audio and video as proof in criminal and all kinds of litigation is increasing, and scientific investigation using digital forensic technique is developing. With the development of computing and file editing technologies, anyone can simply manipulate video files, and the number of cases of manipulating digital data is increasing. As a result, the integrity of the evidence and the reliability of the evidence Is required. In this paper, we propose a technique for extracting the Electrical Network Frequency (ENF) through a grid of power grids according to the geographical environment for power supply, and then performing signal processing for peak detection using QIFFT. Through the detection algorithm using the standard deviation, it was confirmed that the video file was falsified with 73% accuracy and the forgery point was found.

Local government has constructed GIS DB for efficient business achievement and effective management of complex city facilities and has been developing and utilizing application systems, such as Underground Facility Management System Road Management System and so on. However, Facility Management System is providing functions for business, but not for GIS DB's maintenance. City facilities GIS DB managed by GIS technical expert collects basic figure and attribute information through survey and field investigation and is constructed via complex process, such as structurize editing etc. So it has been concerned that the update and confidence of CIS DB can be lower if a business man who does not have enough experiences about Facility Management System operates it by himself. Therefore, functions that enable business users to operate Facility Management System easily should be provided.

Appreciation of nature and an understanding of the biological sciences by the general public are key to the popularization of modern science. In particular, informal and accessible venues such as museum exhibits occupy a crucial role in science education, and they depend heavily on fields related to macrobiology, including Ecology, Animal Behavior, and Environmental Science. Unfortunately, lack of engaged experts and superficial descriptions of natural phenomena all too often prevent scientific knowledge from being shared effectively with the general public. Raw information itself and knowledge are not in a form or structure accessible to nonspecialists. In order to move successfully deliver substantive comprehension of the biological knowledge to the general public, it is necessary to categorize information from a content-conscious perspective and transform it into useful biological content. Therefore, the role of scientists is critically important in a series of processes that include theme selection, editing, and even graphical layout of contents. These processes require not only a scientific and logical way of thinking, but also an aptitude for artistic presentation and effective communication. The concept of Translation is presented as a theoretical and operational framework for the popularization of science.

Zinc finger proteins are among the most extensively applied metalloproteins in the field of biotechnology owing to their unique structural and functional aspects as transcriptional and translational regulators. The classical zinc fingers are the largest family of zinc proteins and they provide critical roles in physiological systems from prokaryotes to eukaryotes. Two cysteine and two histidine residues ($Cys_2His_2$) coordinate to the zinc ion for the structural functions to generate a ${\beta}{\beta}{\alpha}$ fold, and this secondary structure supports specific interactions with their binding partners, including DNA, RNA, lipids, proteins, and small molecules. In this account, the structural similarity and differences of well-known $Cys_2His_2$-type zinc fingers such as zinc interaction factor 268 (ZIF268), transcription factor IIIA (TFIIIA), GAGA, and Ros will be explained. These proteins perform their specific roles in species from archaea to eukaryotes and they show significant structural similarity; however, their aligned amino acids present low sequence homology. These zinc finger proteins have different numbers of domains for their structural roles to maintain biological progress through transcriptional regulations from exogenous stresses. The superimposed structures of these finger domains provide interesting details when these fingers are applied to specific gene binding and editing. The structural information in this study will aid in the selection of unique types of zinc finger applications in vivo and in vitro approaches, because biophysical backgrounds including complex structures and binding affinities aid in the protein design area.

R is a free software for statistical analysis that provides simple interfaces to other application programs. Many people are trying to learn R, but it is difficult to learn R compared to commercial software such as SPSS or SAS, and it is cumbersome to provide an environment to teach R. Thus, it is essential to provide a new web-based R environment for novice users or for laboratory use. We developedWebER (a web-based R environment) using PHP on the Linux apache server. WebER can be easily used by any R user because we implemented the same functions as the basic Rgui such as editing R program, generating the text, image outputs, errors and warnings. It is also possible for multi-users to access WebER.

The effect of Application system with class units is not sufficient because of independency and reuse of Component elements due to component abstraction based on only source code. Therefore We need to apply design pattern approach to represent not only the problem abstraction but also information and relationship between system elements for generic solutions of specific domain, Also, it is essential to software reverse engineering acquiring the correct understandings of the system through examining the existing systems and utilizing the acquired knowledges as reusable resources. In this paper, the extraction algorithm with JAVA and the validity of applying reverse engineering with extracting design patterns from source codes of the existing object-oriented system; are devised. The architecture of automatic tool is designed and implemented for 1) automatic extraction of design patterns and 2) reuse tool for retrieving, editing and rebuilding of design patterns.

For the economic management of photovoltaic power plants, it is necessary to regularly monitor the panels within the plants to detect malfunctions. Thermal infrared image cameras are generally used for monitoring, since malfunctioning panels emit higher temperatures compared to those that are functioning. Recently, technologies that observe photovoltaic arrays by mounting thermal infrared cameras on UAVs (Unmanned Aerial Vehicle) are being developed for the efficient monitoring of large-scale photovoltaic power plants. However, the technologies developed until now have had the shortcomings of having to analyze the images manually to detect malfunctioning panels, which is time-consuming. In this paper, we propose an automatic photovoltaic panel area extraction algorithm for thermal infrared images acquired via a UAV. In the thermal infrared images, panel boundaries are presented as obvious linear features, and the panels are regularly arranged. Therefore, we exaggerate the linear features with a vertical and horizontal filtering algorithm, and apply a modified hierarchical histogram clustering method to extract candidates of panel boundaries. Among the candidates, initial panel areas are extracted by exclusion editing with the results of the photovoltaic array area detection. In this step, thresholding and image morphological algorithms are applied. Finally, panel areas are refined with the geometry of the surrounding panels. The accuracy of the results is evaluated quantitatively by manually digitized data, and a mean completeness of 95.0%, a mean correctness of 96.9%, and mean quality of 92.1 percent are obtained with the proposed algorithm.

Autonomous driving can be limited by only using sensors if the sensor is blocked by sudden changes in surrounding environments or large features such as heavy vehicles. In order to overcome the limitations, the precise road-map has been used additionally. In korea, the NGII (National Geographic Information Institute) produces and supplies high definition map for autonomous vehicles. Accordingly, in this study, errors occurring in the process of e data editing and dtructured esditing of high definition map are systematically typed providing by the National Geographic Information Institute. In addition, by presenting the error search process and solution for each situation, we conducted a study to quickly correct errors in high definition map, and largely classify the error items for shape integrity, spatial relationship, and reference relationship, and examine them in detail. The method was derived.
