The purpose of this study is to organize the system of special characters as UX/UI icon design elements, thus laying the groundwork for improvement direction for unclear use regulations. This study examines the theoretical background of UX/UI design and special characters and discovers UX/UI design and special characters' relations and assignments. Besides, the case study summarizes the system of special characters being utilized in the company's UX/UI icon design guidelines to produce the study results. As a result of the analysis, the special character types being utilized in UX/UI were graphic characters, mathematical symbols, punctuation marks, and parentheses. And the special characters commonly used in analysis cases, iOS, Android, and Windows, are ▶, ♥, ★, ○, ⊙, +, ×, ⋯. So this study organizes the common characters to standardize them. Hopefully, this study contributes to increasing the interest in the study of 'special characters' in the UX/UI design field and helps establish a framework for future industrial standards.

Objective: This study aims to draw an efficient UI design by comparing the usability of App drawer and single-layered home screens, which are smartphone home screens. Background: Because smartphone home screen is frequently used including the installation, deletion, and editing of APPs, it should be designed with easily controllable information structure. There is a need to seek a user-friendly UI by comparing the usability of App drawer and single-layered home screens, of which methods to search Apps are different. There is also a need to examine an efficient UI and the factors to improve from the user perspective. Method: This study targeted 30 Android OS and iOS users to evaluate the App drawer and single-layered home screens, of which UI structures are different. Each participant was instructed to carry out an App searching task and App deleting task, and the execution time and the number of errors were measured. After the tasks were completed, they evaluated satisfaction through a questionnaire survey. Results: In the App searching task with low task level, there was no difference in execution level between the App drawer and single-layered home screens. However, the single-layered home screen showed higher efficiency and accuracy in the App deleting task with high task level. As for the group difference according to use experience, there was no difference in satisfaction among Android OS users, but iOS user satisfaction with single-layered home screen with which they were familiar was higher. Conclusion: As for home screen usability, the single-layered home screen UI structure can be advantageous, as task level is higher. Repulsion was higher, when users, who had used easier UI, used complex UI in comparison with user satisfaction, when users familiar with complex UI used easier UI. A UI indicating the current status with clear label marking through a task flow chart-based analysis, and a UI in which a user can immediately recognize by exposing hidden functions to the first depth were revealed as things to improve. Application: The results of this study are expected to be used as reference data in designing smartphone home screens. Especially, when iOS users use Android OS, the results are presumed to contribute to the reduction of predicted barriers.

The best way to express space effectively on internet is to use 3D VR(Virtual Reality) contents. But it is too difficult to control the 3D VR space with the 2D device. So the content makers cannot solve this problem easily. Besides they define the UI control in their own subjective way which makes the users confused. The purpose of this study is to present the grounds for the Control UI standardization by studying the deriving improvement direction. First of all, we categorize current control UI designs for space-VR on web service by controlling method features into three Types. Next we itemize the main improvement direction that is based on our analysis. First, the UI design that maintains for a typical 2D Input Device method to help the beginner users. Secondly, the concise UI that allows users to Immerse easily in VR. Thirdly, the control level construction that satisfies both users who are skillful at 3D games and users who have little experience with these devices. In this way, we propose the most suitable control UI model that satisfies these improvement directions. We expect the result of our study to serve as an important basis for the standardization of VR services.

Although a great deal of research has been carried out recently with the rise of importance of the UI design, little research has been conducted on the new Neumorphism design. Given the paucity of the research, we demonstrated the development process of GUI design, focusing on the UI design trends, Skeuomorphism, Flat, Material design and the emerging Neumorphism design. Based on this, the aim of the study is to look into the possibility of Neumorphism design, which is currently drawing attention, as the new UI design trends. This study was ordered as follows in two ways. First, drawing from the work of literature, we illustrated the UI design trends by considering the Skeuomorphism, Flat, and Material Design which were before the advent of the Neumorphism design. In addition, we conducted a study on the characteristics and limitations of the UI design trends through actual cases in which UI designs were applied. Second, the Material design as the most recent UI design trends and the Neumorphism design were compared with the method of expression based on the definition and characteristics of Neumorphism design that we investigated. In this context, we also analyzed the possibility of Neumorphism becoming the new UI design trend. We proposed an application of the design to maximize the benefits. This study is meaningful in that the Neumorphism design, which has yet to be studied, is likely to become the UI design trends in the future.

On-line game gradually grew into a significant part in Korean culture due to rapid development of internet. As icons are utilized as interface, the concept of UI(User Interface) receives spotlight in playing games, and the play bug appears most frequently in MMORPG genre. The introduction of icons brought partial inefficiency in dividing screen sectors while playing games, which means play sector is reduced. On the meantime, components of UI possess different places so that cause considerable confusion to heavy users. This study attempts to analyze the top 5 commonly-played games and to understand the necessity and status of UI components by surveying heavy users. The result of this study shows that there is notable difference between UI of games on-service and preference of heavy users. This study could suggest UI of a better quality by restructuring and rearranging the UI components based on the heavy users' preference as shown in the survey. It is expected that this study can contribute to creating a more effective game play by eliminating possible changes of UI upon different games and realizing broader play sector.

In this study, we developed mixed matrix membranes by blending thermoplastic elastomer, i.e. polystyreneblock-polybutadiene-block-polystyrene (SBS) block copolymer with the synthesized UiO-66 particles for CO₂/N₂ gas separation. To investigate the effect of UiO-66 particles in the SBS matrix, we prepared different mixed matrix membranes (MMMs) by varying the mass ratio of SBS and UiO-66 in the blend. To fabricate well-dispersed UiO-66, the SBS/UiO-66 mixture was sonicated and stirred thoroughly. The physico-chemical properties of prepared membranes were characterized by Fourier transform infrared spectroscopy (FT-IR) and scanning electron microscope (SEM). The gas separation performance was measured by time-lag method. The permeability of the MMMs increased significantly as the content of UiO-66 increased, but the CO₂/N₂ selectivity did not decrease significantly. The membranes containing 20% of UiO-66 particles showed the best performance with the CO₂ permeability and CO₂/N₂ selectivity of 663.8 barrer and 13.3, respectively. This result showed performance closer to upper bound than pure SBS membrane in the Robeson plot, as the added UiO-66 particles did not significantly sacrifice selectivity and more than doubled gas permeability.
