A case study was conducted to investigate the characteristics of the visual components affecting the integrated identity design of Winter Olympics for its establishment. The targets of the investigation were limited to the Winter Olympics held after 2010, including the Vancouver, Sochi, and Pyeongchang Winter Olympics. The first survey investigated the characteristics of the visual components, and the second survey analyzed the design characteristics, including connectivity, variability, expandability, and connectivity and could draw the following results. The integrated identity of Winter Olympics maintained the connectivity, providing the integrated recognition of visual components, and there was a variability according to its use. In addition, connective images were maintained with each other. However, it was noted that there was little expandability utilized flexibly according to the applied media in the emblem and slogan even in the various changes. Hopefully, these results will be utilized as the basic data for the development of integrated identity strategies, effective for the production of the design of the emblem of the Olympics in the future.

This paper presents critical steps in building client/server application with UML and Visual Basic, which are derived from the implementation case of a typical order processing system. To begin with, we briefly review the software architecture, the diagrams and the object-oriened building process in the UML. In the inception phase, it is critical to define the project charter, to draw use case diagrams, and to construct a preliminary architecture of the application. In the elaboration phase, it is critical to identify classes to be displayed in the class diagram, to develop user interface prototypes for each use case, to construct sequence diagram for each use case, and finally to design an implementation architecture. Steps to construct implementation architecture are given. In the construction phase, it is critical to design both the database and components. Steps to design these components are described in detail. Additionally the way to create the Internet interface is suggested.

The purpose of this study is to observe the brain activity patterns during visual oddball tasks with two difficulty levels by the analysis of high-density event-related potential (ERP). Along with conventional statistical analysis of averaged ERP waveforms, we applied independent component analysis (ICA) for the individual, single-trial analysis and verified its effectiveness. We could identify multiple ERP components such as early visual components (P1, N1), and two components which seem to be important task-related components and showed difficulty-dependent variability (P2, P300). The P2 was found around central region at $180{\sim}220ms$, and the P300 was found globally at $300{\sim}500ms$ poststimulus. As the task became difficult, the P2 amplitude increased, and the P300 amplitude decreased. After single-trial ERPs were decomposed into multiple independent components (ICs), several ICs resulting from P2 and P300 sources were identified. These ICs were projected onto scalp electrodes and the projected ICs were statistically compared according to two task difficulties. For most subjects, the results obtained from single-trial/individual analysis using ICA gave the tendencies of amplitude change that are similar to the averaged ERP analysis for most subjects. The temporal pattern and number of ICs corresponding to ${\mu}$ rhythm was not dependent on the task difficulty. It seems that the motor response was not affected by the task difficulty.

The contrast of the intensity components of color images usually needs to be improved in order to enhance the visual quality of color images. However, pure color regions can be saturated due to the excessive enhancement of that color. In this paper, a new method for enhancing the visual quality of color images using saturation components in the HSI color space is proposed, and the same enhancement technique in the YCbCr color space is proposed. Computer simulations show that the proposed method provides improved visual quality compared to the conventional methods.

The purpose of this research is to study the visual characteristics of domestic national men's wear brand logos. For this purpose, 80 of national men's wear brands were selected from '2010/2011 Korea fashion brand Annual' For analysis, they were classified into three categories: logo types composed only with logomark or symbol and logomark together. Types of symbol were classified into word symbol, descriptive symbol, and abstractive symbol. And the used typefaces were classified into serif and san serif and acromatic and cromatic The results are as follows: The visual characteristics of domestic national men's wear brand logos, there were more brands that used logomark with symbol together than logomark only. And the type of symbols were appeared descriptive symbol(32% ) that meaned the men's power, nobleness and royalty. In domestic national men's wear brands, color of logos were more frequently used acromatic color as black and grey than cromatic color. Among the cromatic colors were more appeared to a kind of blue and green. And the used typefaces were the more frequently used to serif typeface of capital. As a result, the visual characteristics of domestic national men's wear brand logo were that they used the brand logos composed of descriptive logomark with symbol together, black serif typeface the most. From this results, we could find that visual stragety of domestic national men's wear brand logos had the tendency to emphasize the function of conveying information, brand concept that men's wear. The specific and continuous following research in which psychological factor of consumer reflected was requested as a measure to seek brand logo that aid to establish brand power and reinforce brand image.

This study will examine the visual composition by which Secretly Greatly, in a circumstance that even the good original Manhwas or Webtoon have not made a hit on the market until now, could attract the spectator, in other word, illustrate the analogousness of the images through analysing visual texts. The study draw, first of all, a meaning of the box office performance caused by analogousness of image, that is similarity between the webtoon and film. In addition, the study will come up with an answer to the question that the webtoon, not in a temporary trend but in a sustainable form, can make itself develop. For this, the study suggests a meaning, worth and importance of the transformation, analysing visual components of a webtoon to film adaptation, Secretly Greatly. It primarily ranges over visual components, mise-en-scène identified with its expression formula, frame to frame changes and colour and tone. The examination sets the cinema's visual expression manner against the webtoon's on their concrete components: the size of scene, movement, color and tone, narrative condition and its background, spatial composition and depth, contrast, expression manner and disposition manner.

In the paper, a Visual factory model for a optical-components manufacturing process is built. The optical-components manufacturing process is composed of 3 operation processes; optical sub assembly process, package assembly process, and fiber assembly process. Each process is managed not a batch mode, which is one of most popular manufacturing styles to produce a great deal of industrial output, but though a modular cell. In the processes, a modular cell has to be processed independently of the other cells. Optimization for the composition of assembly cell in the optical-components system is made by the Visual factory model.

Using standard components of a press die is recognized as a way for a cost reduction and a short lead time. It also provides a way for a quick maintenance of a die under repair. It is expected to contribute to integration of CAD/CAM system for manufacturing dies in the future. This paper presents a 3D CAD library which is constructed using the standard components and is used for designing a press die. This 3D CAD library is generated by a database system made of Microsoft Access for standard components and by CATIA V5 R10 API for geometric features. The library is implemented using Visual Basic 6.0 utility of CATIA API function in the Windows NT environment. It creates a 3D model of the standard components of press die easily when a die designer inputs numerical values of geometric features and the BOM of the completely assembled parts. It also generates automatically the assembly drawing of die set by using variables for standard values of die parts. Therefore users can save the cost of time to design the press die components, and even a beginner can use this program with ease. The test results of the 3D CAD library for designing shearing and bending dies verify its usefulness and feasibility.
