This study investigated the current status of the design and direction of improvement of the sign system of urban railway stations in the Seoul metropolitan area to see how difficult it is for users to use. As a research method, first, a theoretical study on the literature of the urban railway sign system, second, a survey on the current status of the sign design of the Gimpo Goldline in the Seoul metropolitan area, and third, a survey on the actual use of the sign and problems was conducted. As a result of the current status survey, the location sign is in central alignment with the font of the guide sign, and the guidance sign is in front/back alignment according to the location of the entrance and exit. The background of the font is white and the text is dark black to make it look good to the user. On the other hand, guidance sign is written in white color and background color is gray color. Currently, the Gimpo Urban Railway Guidance Sign System is newly produced and installed, but there is a lack of user design and needs design maintenance that can clearly deliver information to users.

This paper presents the two degree-of-freedom(DOF) planar parallel mechanism called 2R$\underline{P}$R-RP manipulator, whose degree-of freedom is dependent on a passive constraining leg connecting the base and the platform. First, the kinematic analysis of the mechanism is performed analytically: the inverse and forward kinematic problems are solved in the closed font the practical workspace is systematically derived, and all of the singular configurations are examined. Then, in order to determine the geometric parameters and the operating limits of the actuators, the optimization of the mechanism is performed considering its dexterity and stiffness. Finally, the kinematic performances of the optimized mechanism are evaluated through comparing to the 5-bar parallel manipulator.

In this study, I wanted to propose the design direction of the furniture and products in bathroom space so that the elderly's life is well supported to meet such aging societies that are getting older. Therefore, I have drawn the elders' needs by investigating their characteristics through literature research and used such needs as a frame of analysis to analyze the bathroom furniture and products made in Korea and foreign countries. The analysis results indicate:First, the elders need entertainment, health care, environment-friendly, convenience, good accessibility, chair-based bath and space separation; second, both Korean-made and foreign-made bathroom products are difficult to be controlled, invisible of font, hard to sustain the elders' bodies, inconvenient to be used and etc; and third, the design to solve such problems should be with intuitive user interface, easy control, better accessibility, the elders' moving patterns and living habits considered, health care, pro-environmental product. This study puts emphasis on the reflection of socio-cultural characteristics in designing bathroom furniture & items for aging society and requires more bathroom products with various designs in the foreseeable future.

We suggest the development of a mobile muscular savings account application as a more effective and consistent strategy to avoid sarcopenia, one of the elderly diseases, based on the researcher's experience conducting a handwritten 'muscle saving account' in the S city of the metropolitan area. The analysis of currently existent healthcare-related applications shows that muscle strength improvement and maintenance applications are needed to improve easy use and access without burden for elderly users because there are many functions, and it can be difficult for the elderly to use the application. A survey of participants who used handwritten 'muscle savings accounts' was conducted before the design development to measure user satisfaction. Based on this, the suggested application's design is similar to the handwritten type, functionalities are modified for easy usage by the elderly, and information is intuitively comprehended and presented properly using color contrast and Sans serif font. We plan to conduct a survey of the elderly who did not participate in the project as part of follow-up research, and afterward continue the research on the development of customized applications optimized for the prevention of sarcopenia in the elderly for muscle strength improvement and maintenance based on the results.

Seal is a tool to prove an individual or group. Guk-Sae and Eo-Bo uses typeface to represent their names or titles, which change from tensile to tensile and have varied from time to time. Although the Korean alphabet currently uses Hangul, it had used Chinese characters before Hun-Min-Jeong-Um was created in 1443. All seals and royal seal before the Korean Seal of State were made in Chinese characters. This thesis analyzes the concept of typography through the royal seal, and the subject of this study is 'Sugang Emperor' which is the only eight-letter version seal of the Joseon Dynasty's various royal seal. Bo-Yeong, which is shown in Bo-Myeon has artistic value with beautiful typeface and proportions, which is worth research. It examines the features of the Korean seal, analyzes and studies the typeface shape and features from the typographic perspective of the "Sugang Emperor Bo-Yeong," or writing.

The purpose of this paper is to provide a search system using a method of accessing the web in real time without using a database server in order to guarantee the up-to-date information in a single network, rather than using a plurality of bots connected by a wide area network Design. The method of the research is to design and analyze the system which can search the person and keyword quickly and accurately in crepe system. In the crepe server, when the user registers information, the body tag matching conversion process stores all the information as it is, since various styles are applied to each user, such as a font, a font size, and a color. The crepe server does not cause a problem of body tag matching. However, when executing the crepe retrieval system, the style and characteristics of users can not be formalized. This problem can be solved by using the html_img_parser function and the Go language html parser package. By applying queues and multiple threads to a general-purpose web crawler, rather than a web crawler design that targets a specific site, it is possible to utilize a multiplier that quickly and efficiently searches and collects various web sites in various applications.

VMS(Variable Message Sign) helps drivers to choose their path to destinations on roadways. Some types of VMS often provide traffic information with clearly visible and comprehensible graphical route diagrams. Currently many diagramed types of VMS are installed on urban arterial and highways. This type of VMS surely enhances drivers' ability to comprehend traffic route information while they are driving on the roadway. Nevertheless, some of them are presented with so much information and design elements and they sometimes lead to decline of drivers' comprehensible level for traffic information. Drivers would fail to decide their preferable route in this state of information overflow. The purpose of this paper is to develop a drivers preference model for effective design principle including size and height of displaying font, and the amount of information in the route diagram considering driving speed, sex and age of the driver. This model is developed using structural equation modeling techniques. This model considers driver's emotional factor and, human factor and design component of route diagram. To collect data, we built driving simulator which is able to replicate real driving condition. 72 people who participated in the simulation were selected considering gender and age. The developed model showed that the amount of information, and visibility are more influential factors to the drivers' preference of the route diagram on VMS than design elements such as the shape and the font of the diagram.

The visual presentation is one key feature which gives much consideration in designing mobile applications as it acquires attention from the end user. It takes only a few milliseconds to form an impression on a person and this is not any different to the web and mobile application designs. The first few milliseconds are a crucial time for developers as the impression produced would indicate further engagement of the service. Developers should continuously update the designs based on human needs. A few of these contents have actually paved its way to being continuously used. By synthesizing results of preceding researchers, this paper considers layout, color, and font as UI design elements of SNS messenger, and illustration and animation as the graphic image of it. In this study, the preference for messaging application chat layout was being surveyed and analyzed. As a result, there has been little significance identified since the instant messaging, so chat layout shows very minimal variance in their design.

The purpose of this paper is to study the direction of improving kiosk design for convenient use by all users by increasing the usability of kiosks based on universal design principles. The direction of design improvement was studied by deriving essential improvements through additional surveys verifying the results of age-specific surveys and analysis related to the use of kiosks. The results of the study are as follows. High contrast between kiosk screen background and design elements, yellow color, and outline design elements increase readability. Then, reduce and enlarge the font based on 10pt. In addition, in consideration of wheelchair passengers, the area where the lower part cannot be designed and the minimum height of adjusting the height of the kiosk were derived. In the future, kiosk design requires a design and system that can diversify the functions of kiosks according to individual characteristics, and design should be focused on the application of universal design. Since this study has limited research subjects, further studies on various samples are required, and verification studies related to color and readability will also be conducted.
