Even though graphical simulation is very useful for construction planning, the application of graphical simulation has a limitation in dealing with objects without fixed form like earthmoving process. In this case, the mathematical/statistical simulation about the productivity of the whole processes based on the numerical data of working time, waiting time and working capacity of using equipment becomes effective. The mathematical/statistical simulation is not fully utilized in the field of construction due to the difficulties of creating process models and securing trust the numerically expressed results of simulation. In this research, the output of discrete-event simulation programs which are the most common mathematical/statistical simulation tool for construction processes were analyzed for the purpose of earthmoving process visualization. The purpose of this research is to develop a graphical simulation system that can help the construction planner select most suitable equipment and construction methods through the visualize the numerical simulation results of the working time, the queuing time as well as the amount resources etc.

issued in the U.S is a magazine specialized in graphic design, which has a totally different style from commercial magazines such as show case. The main motive why Rudy VanderLans, the publisher, first issued this magazine in the early 1980s is his assertion that there is no design paradigm of universial concept in the aspect of viaual communication design. Also, it started from his recognition that a medium for letting a new generation's show their liberal thinking and experimental expressions. This study looks at theologies and assertions on new graphic concept, which is called the New Wave of graphic design by classifying the plans of into form and contents, and analyzes its specialty in design. Also, this study examines the overall trends of non-Grid editorial design since the modern style. By doing so, I could have a general look at the progressive traits and their futuristic directions that become to have a shorter life cycle with the advent of the 21st century's information era, high-tech media and the change of production environment by digital technology.

In this study, we tried to produce moving-image works through sentiment analysis of music. First, Google natural language API was used for the sentiment analysis of lyrics, then the result was applied to the image visualization rules. In prior engineering researches, text-based sentiment analysis has been conducted to understand users' emotions and attitudes by analyzing users' comments and reviews in social media. In this study, the data was used as a material for the creation of artworks so that it could be used for aesthetic expressions. From the machine's point of view, emotions are substituted with numbers, so there is a limit to normalization and standardization. Therefore, we tried to overcome these limitations by linking the results of sentiment analysis of lyrics data with the rules of formative elements in visual arts. This study aims to transform existing traditional art works such as literature, music, painting, and dance to a new form of arts based on the viewpoint of the machine, while reflecting the current era in which artificial intelligence even attempts to create artworks that are advanced mental products of human beings. In addition, it is expected that it will be expanded to an educational platform that facilitates creative activities, psychological analysis, and communication for people with developmental disabilities who have difficulty expressing emotions.

Until now, a lot of image quality assessment techniques or tools for optimal human visual system(HVS)-awareness have been researched and SSIM(Structural SIMilarity) and its improved techniques are representative examples. However, they often cannot cope with various images and different distortion types robustly, and thus this can cause a large gap between their index values and HVS-awareness. In this paper, we conduct image quality assessment on SSIM and its variants intensively and analyze the causes of each component function's observed anomalies. Then, we propose a novel image quality assessment technique to compensate and improve such anomalies. Additionally, through extensive image assessment simulations, we show that the proposed technique can indicate HVS-awareness more robustly and consistently than SSIM and its variants for various images and different distortion types.

This study designed and implemented a query model for consecutive analyses of dynamic multivariate graph data. First, the query model consists of two procedures; setting the discriminant function, and determining an alteration method. Second, the query model was implemented as a query system that consists of a query panel, a graph visualization panel, and a property panel. A Node-Link Diagram and the Force-Directed Graph Drawing algorithm were used for the visualization of the graph. The results of the queries are visually presented through the graph visualization panel. Finally, this study used the data of worldwide import & export data of small arms to verify our model. The significance of this research is in the fact that, through the model which is able to conduct consecutive analyses on dynamic graph data, it helps overcome the limitations of previous models which can only perform discrete analysis on dynamic data. This research is expected to contribute to future studies such as online decision making and complex network analysis, that use dynamic graph models.

This study aims to highlight the social aspects of genetic discrimination as another shadow that biotechnology can influence on social life. To do so, the definition of "genetic discrimination" and three perspectives (exceptionalism, expressivism, and human right discourse) were reviewed. In addition, the Genetic Information Nondiscrimination Act (GINA) of the United States and the Bioethics and Safety Act of Korea were analyzed. Several social implications for establishing the research and policies of genetic discrimination based on the existing research results of perceived genetic discrimination (the experiences, fears, and coping strategies of genetic discrimination) were suggested. These included public consensus on the definition of genetic discrimination and emphasis on a human rights approach against genetic discrimination; concerns regarding genetic discrimination in both the personal and public domains; raising the consciousness of both health care providers and the public regarding genetic discrimination; and developing psycho-social coping strategies for decreasing the fear of discrimination of asymptomatic people (hereditary carriers).

본 논문에서는 기존 철도 운영 및 관리시에 철도 주변환경으로 부터 발생하는 소음, 진동, 미세먼지 센서에서 다양한 실시간 스트림 데이터를 감지하고 정형화된된 데이터 패턴을 인식하고 분석할 수 있도록 데이터를 구성 및 저장하고 분석된 데이터를 표현할 수 있도록 시각화 지원을 위한 모니터링 시스템 플랫폼을 구현하였다. 데이터 전송을 위해 시리얼 통신 기법을 주로 적용하였으나, 센서와 디바이스의 증가로 인해 시리얼 통신의 한계가 나타났다. 따라서, 본 연구에서는 기존의 아두이노와 서버 간의 직접 통신 방식 대신 라즈베리파이를 도입하여 MQTT Broker(브로커)를 설치하고 통신을 진행하였다. 철도 데이터 모니터링 시스템 플랫폼은 NoSQL 데이터베이스인 MonGoDB와 데이터 시각화할 수 있는 Grafana를 이용하여 구축하였다.

Role of music in an image can be divided into a supplementary function to express narrative of image and an independent function to become the subject of music and to lead the image. To perceive sound through hearing and then, to make it visualized is called visual music. Since the 19th century, image synchronization of music through colored hearing has been continuously attempted by artists in their works. Also in the 20th century, many artists could attempt time-wise concept of movement passing the bounds of three-dimensional expression due to development of cinema. In such a process, artists with strong experimental spirits inferred correlation between sound and image and then, pioneered new genre of visual music. As a result, the times are being changed from those of listening to those of watching, and various works are being produced by experimental attempt of various music and images. This thesis aims to investigate aesthetic characteristics of modern visual music and then, to conduct comparative analysis on how visual music using colors are utilized in diversified fields such as movie, animation, music video and media art.

Robotic motion is designed by the rotation and the translation of multiple joint coordinates in a three-dimensional space. Joint coordinates are generally modeled by homogeneous transform matrix. However, the complexity of three dimensional motions prefers the visualization methods based on simulation environments in which models and generated motions work properly. Many simulation environments have the limitations of usability and functional extension from platform dependency and interpretation of predefined commands. This paper proposes the web-based three dimensional simulation environment toward high user accessibility. Also, it covers the small size web server that is linked with Python script. The non linearities of robot control apply to verify the computing efficiency, the process management, and the extendability of user scripts.

의미 기반 영상 검색은 Color, Texture, Region 정보, Spatial Color Distribution등의 저차원 특징 정보와 이미지 데이터에 의미를 부여하기 위해 주서 처리하는 것이 일반적이다. 그리고 부여된 키워드나 시소러스와 같은 어휘 사전을 이용하여 의미기반 정보검색을 수행하고 있지만, 기존의 키워드기반 텍스트 정보검색의 한계를 벗어나지 못하는 문제를 야기 시킨다. 이에 본 논문에서는 시각 데이터에 존재하는 객체들과 그 객체 사이의 개념관계를 Ontology의 한 형태인 WordNet을 이용하여 의미 정보로 표현할 수 있도록 한다. 이를 활용하면 영상 데이터의 자동 주석 시스템이나 검색 시스템에서 인간이 인식하는 개념적인 사고방식에 더욱 접근할 수 있는 결과물을 얻을 수 있을 것이다.
