This study describes the semantic theoretic interpretation through the extensive use of semantic metaphors for intensive web interface with information and the metaphoric value of metaphors for interface design. Common factors that influence web design are empirical establishment and verification for generating web symbols and these are have important elemental perspectives that are used to assess the usefulness and key elements of the site. In addition, the structure of the screen has begun to change dynamically from the application of web technological functions, and the media functions have become important to make web standards when implementing visual structuring from the perspective of semiotic. Instead of using a technical expression approach to examine semiotic, a semiotic approach is applied to create aesthetic codes through the human-computer interface in terms of semiotic in a variety of natural and universal fields. Based on this, it is used as means of communication to convey the intended meaning to users so as to highlight the importance of the usability issues and metaphors user interface.

Nowadays, the studies on interface and cognition-engineering has become issues of general interest as newly design-methods which analyze the behavior of user on products. However existing studies were mainly done with verbal-centered method which made it difficult for the designer to apply for visual realization. Moreover many mistakes and noises are taken place whenever the designer converts verbal statements and needs of user into visual factors. Therefore the designer needs to analyze visual perception on user and product as visual-centered methods. This study applies the eye tracking method as analysing-instrument and aims to develop the analysis-framework, the concrete techniques of measurement and the application for the product design. At first the nature and the process of visual perception on products are reviewed for developing analysis method. Then the technique of eye tracking and the meaning of fixation and movement are discussed to specify the concrete method. The basic experiment of product can reveal general analysis process, advantage and guideline for the application of eye tracking method. The Study is peformed through the following 4 steps ; to pre-research into product design and visual perception theory ; to identify the concrete experiment method, to measure the fixation/movement data and analyze the raw data, to convert the result of analysis to the visual framework. Finally the major findings and the limits of the study are suggested and summarized.

Recently a mobile service is changing into a system environment that offers the customer various contents service. Representative example of service is a Calling Identity Del ivory Service(CID). Such service has the problem in the case which the receiver cannot remember the phone number of the sender; it has a difficult problem that cannot easily confirm whose the phone number it is. Therefore, it is desirable to design and implement visual services that can enhance the recognition of users. In this paper, we propose the architecture that is similar to a Calling Identity Delivery Service. We propose the architecture for communication service and system that is able to visually display the information of the sender using 2D image data in mobile environment. After that we set the image information to represent the user and this method is able to visually display the information of the sender by transmitting an image data through channels from switch station or base station using the server. When the receiver receives a phone call from the sender, this method provides an efficient service by transmitting visual data with bell sound. That is, the image information of sender is appeared on liquid crystal display(LCD) of the receiver at the same time. We investigate the concepts for processing real-time transmission of image data and describe an example of the implementation result that is based on system. This technology has a potential influence on the marketing and presents an efficiency of this method.

As the main mathematical concepts are presented and expressed in various ways through textbooks during the teaching and learning process, it is necessary to look at the representations used in elementary math textbooks to find effective guidance. This study analyzed sentences used in the definition of mathematical terms and unit assessments of current elementary mathematics textbooks according to word depth (Yngve, 1960) from a syntactic perspective. As a result of the analysis, it could be seen that the sentences in textbook were generally concise, the word depth was lower, and the sentence structure and form were different depending on the individual characteristics of each term. Also, the sentences in the lower grade textbooks were more easily constructed, and the sentences of the term definition were more complex than the sentences of the unit assessments. Efforts should be made to help learners learn mathematical concepts, such as clarifying sentences in textbooks, presenting visual materials together, and providing additional explanations to suit the level of individual learners.

For cities with ancient buildings at core areas, night lighting is an effective means to demonstrate their history and culture. In this regard, night scenes of these ancient buildings are evaluated from multiple aspects, such as color rendition, brightness ratio affected by ambient light and technological realization of lighting facilities. This study builds a visual evaluation system for night scenes of ancient buildings based on three dimensions, namely ancient architecture carrier performance, visual perception and technological realization, and explains specific evaluation sub-criteria one by one. In addition, this study adopts Analytic Hierarchy Process (AHP) to analyze the impact of each sub-criteria item on the weight of the whole evaluation system, and conducts a consistency test to show that the evaluation system meets the reasonable requirements of hierarchy setting. Moreover, relative importance of each sub-criteria item may be determined based on their corresponding weights.

Children's films can be found by country and region within the scope of world films, but children's films have different definitions depending on the country and region. For example, American children's films represented by Disney are mainly aimed at satisfying the joys of children and families.Chinese children's films place more importance on the educational role of children. Although the purpose is different, children's films in the general sense are films that main audiences are children and are created for children. Children's films in Iran differ greatly from ordinary children's films. It indirectly expresses the creator's intention by reflecting reality while looking at the adult world through the eyes of children. This special function is a children's visual language that indirectly conveys the creator's thoughts. The use of children's perspective is a kind of special strategy, paving the way for Iranian films to survive in a special creative environment, and creating unique characteristics of Iranian films. Among the numerous Iranian directors who make children's films, Majid Majidi is one of the representative directors with personal characteristics. Of his nine Iranian films written and directed, five are children's films.At the same time, in his other Iranian films, we can more or less see the traces of children and children's perspective of the narrative and performance.Looking at the use of children's vision in Iranian films, the use of children's vision in Iranian films began with children's films and developed in Iranian children's films and other genres of Iranian films.

데이터베이스 전문 사용자가 아닌 일반 유저들도 쉽게 데이터베이스에 접근하고자 하는 요구들이 늘어나고 있다. 이러한 요구사항을 만족시킬 수 있는 방법 중 하나가 Graphical Query를 사용하는 것이다. Graphical Query는 유저에게 Schema browsing 매커니즘을 제공하여 텍스트를 기반의 질의보다 쉽게 데이터베이스에 접근할 수 있기 때문이다. 본 논문에서는 Tachyon OODBMS을 위한 그래픽 질의어 TGQL(Tachyon Graphical Query Language)의 설계 및 구현에 대해 서술한다. TGQL은 객체 DBMS를 위한 그래픽 질의어이므로 객체지향 개념을 어떻게 그래픽 질의어에 시각적인 요소들로 반영시키는가 라는 문제가 중요하게 다루어진다. 본 논문은 이러한 측면에서 TGQL의 특징들을 기술한다.
