The Manual on Uniform Traffic Control Devices advises that, "Signs should be placed on the right side of the roadway where they are easily recognized and understood by road users." Guidance is provided on the spacing and prioritization of signs, and in some conditions, additional steps may be needed to ensure that signs are conspicuous. This study proposes a design methodology using ergonomics concepts applied to traffic sign and street name signs. Initially, a literature revision on cognitive ergonomics is performed. Several design methodologies are analyzed and the aspects to be considered in traffic signs are selected.. In this study, problems of traffic signs in Korea were identified through the comparative analysis of domestic and foreign traffic signs and a prototype of ergonomic traffic sign was developed based on the analysis results. And the driver's views on the developed traffic sign were investigated. In addition, based on the results of this study, this study is to provide the necessary foundation for improving traffic signs in order to help the various age groups of drivers to reach their destinations without difficulties when they drive.

The premise of this study is that an ultimate objective in planning an exhibition space is spectators' experiences shaped by a result of their first-hand experiences and responses within an exhibition space, and this result can be recognized in the spectators' movement. Thus, the sign system that can directly affects viewers' main line of flow and movement patterns was examined vis--vis a mutually complementary relation in a triangular composition with the structure of exhibition space and the exhibition contents. Based on the findings, predictive values before and after a complementary application of the sign system to the structure of exhibition space was analyzed and its validity was assessed. The results of this research analysis were drawn as follows. It was shown that an understanding of the locations of direction signs and the degree of recognition can function as an important factor to predict viewers' movement, along with an understanding of topological characteristics of an exhibition space. In terms of the connection and disconnection of space units that form the space structure, it suggests that the distribution of signs and the degree of recognition can adjust the degree of connection and disconnection. Even though exhibition spaces for research subjects were selected from a relatively large number of museums, but the research was limited with a focus on the structure of exhibition space and sign systems. Thus, it is proposed that future studies should be conducted by including varieties of exhibition and environmental factors.

The communication environment made by digital technologies has made it possible to exchange information and deliver messages fast and easily among people of various classes in virtual space beyond time and space. Net-generation, who is accustomed to this virtual space, couldn't be satisfied with the linear text-oriented language any more, and began to make signs by use of computers in order to differentiate itself from others and to express its desires. Among the signs, emoticon created by joint of popular culture and digital communication centering around young generation is a new visual sign and emotional sign that can deliver a sender's feelings contained in a message. This paper has studied social phenomena, their relationships with emoticon and background of its creation through documentary review of media development, changes in the communication environment and popular culture. Furthermore, it has analyzed the meaningful action and roles of emoticon as a sign in terms of semiotics and also, studied a possibility of using emoticon as a new emotional sign. The study results say that emoticon can play the roles of a non-linguistic sign just like general signs that make mutual exchange through meaningful action, and also that it can be used to effectively deliver messages not only in virtual space, but also in advertising, posters, magazines and CI. However, emoticon is better at emotional expressions yet than other textual signs or visual signs, but in order to position itself as a universal and popular sign, emotional expressions should be clear, any difference in understanding messages should be removed, and message delivery should be more efficient.

The People usually adapt themselves to circumstances and its changes. in some cases they are try to improve it for better comfortable living environment. However various factors such as a building's own character cultual symbolism cause some problems in creating interior environment because of inappropriate visual communication. It is general fact that the problems of visual environment objects have not been solved organically under the total environmental concept. In this paper I try to find out how graphic symbol sign system a visual transfer process between people and phsical environment facts work on creating interior environmental analysis current cases and propose a solution.

Sign language was designed for the deaf and dumb people to allow them to communicate with others and connect to the society. However, sign language is uncommon to the rest of the society. The unresolved communication barrier had eventually isolated deaf and dumb people from the society. Hence, this study focused on design and implementation of a wearable sign language interpreter. 6 inertial measurement unit (IMU) were placed on back of hand palm and each fingertips to capture hand and finger movements and orientations. Total of 28 proposed word-based American Sign Language were collected during the experiment, while 156 features were extracted from the collected data for classification. With the used of the long short-term memory (LSTM) algorithm, this system achieved up to 99.89% of accuracy. The high accuracy system performance indicated that this proposed system has a great potential to serve the deaf and dumb communities and resolve the communication gap.

Information is the most important rather then wealth in the information age. According to propagation of the information by new media, this era is called communication innovation age. And away of thought and life style as well as a society system are changing. Propagation by newspaper and TV as well as new media makes new view on value of consumers, and they recognize propensity to consume as needs from emotion rather than economical value. Changes of thoughts make lots of innovation:from one side, modern design to multi-meanimg design, from consuming of products to consuming of the image, from outer object to inner object, from consuming by mass to consuming individually by fashion. It means the possibilities that a meaning could be interpreted variously. Sign is a configuration for communication with discourse, which is the communication between meaning maker and meaning solver. In this study, various expression of sign in advertising were divided into direct expression and metaphoritical expression which was analysed deeply because it was recoquized as proper expression methed in postmodem design.

The objective of study is to evaluate design standards related to the allowable truck speeds, taper length and sign requirements together with the operating practices and economic justification for climbing lanes. Field surveys were carried out on seven climbing lanes, three on two-lane and four on four-lane freeways. Data collected are traffic volume, speed, usage rate and delay. It is found that current design criteria for determining the length of climbing lane, taper lengths, and traffic sign requirements must be upgraded. It is also recommended that regulations on the use of climbing lane be established to make it more effective. Further, economic analysis revealed that the climbing lane is economically justified for two-lane and four-lane freeway if the AADT is over 4,577 and 5,116 vehicles respectively.
