UiO-66 particles were synthesized under various synthesis conditions to study the adsorption of carbon dioxide for hydrogen purification. For the purpose, the design and analysis of experiments was performed using statistical design of experiment method. As the synthesis time, temperature and acetic acid amount increased, the crystallinity of UiO-66 particles increased. Especially, the amount of acetic acid was confirmed as an important factor in determining the crystallinity of the particles. The specific surface area of the particles measured by the nitrogen adsorption method also showed a similar tendency. Using the general factor analysis in the experimental design method, the main effects and interactions of major factors were analyzed. In addition, the carbon dioxide adsorption capacity was predicted using a nonlinear regression method. Then, the adsorption performance was shown through surface and contour maps for all ranges.

Innovator and Early Adopter are main clients of smart phone until now, but the silver generation enjoying price stability and the Internet emerges, so a strategy of the importance, systematic classification, and focus of a neglected class is needed. It is necessary to analyze UI that can departmentalize not a neglected class limited to the silver generation but potential users who can be voluntarily users and can secure them. To secure them, the researcher analyzes how Windows, Icons, Mouse Pull-Down-Menus(WIMP) of UI has been applied in the process that skeuomorphism UI of iPhone, Metro UI of MS, and Material UI of Google change. As a result of an analysis, skeuomorphism is not entirely new and has secured potential users slowly with a method to compensate and improve a part that users disregard. As a concept of touch UI, Metro UI considered potential users from the beginning but did not secure them with new and epoch-making UI. However, Material UI of Google compensates the weaknesses of skeuomorphism UI and Metro UI and emphasizes cost-effectiveness, so has developed into UI that can secure final consumers of potential users. Therefore, to secure potential users, it should make users themselves understand why they should use smart phone, and it should approach with more organized studies on UI through feedback of observation and direct talks.

An attractive user interface (UI) design with a clear user experience (UX) is the key for the success of applications. Therefore software development projects require very close collaboration between SI developers and front-end service developers. However, methodologies for software development only exist with inadequate development processes or work standards for collaboration. This survey derived 13 risk factors in developing UI/UX from 113 risk factors of IT projects through a questionnaire and factor analysis and proposed a collaboration-based UI/UX development model that can eliminate or mitigate six risks with high weights and reliability. To extract risk factors with high reliability, factor and reliability were analyzed to extract 13 major risks, and based on the expert opinions and the results of correlation analysis, UI/UX development stages were classified into planning, design, and implementation. The causal relationships between risks were verified through regression analysis. This study is the first to expertly analyze major risks based on collaboration in UI/UX development and derive a theoretical basis that can be used in project risk management. These findings are expected to provide a basis for research on development methodologies for higher levels of front-end services and to construct rational collaboration systems between SI practitioners and front-end service providers.

In a software development process, it is necessary to have a method which verifies and satisfies users' requirements in their point of view. This allows the system developer to design a high qualify software system and have it developed and used in an effective way since users' requirements have well been shown through it. In this paper, we propose the RV-UI model system that can verify users' requirements a step ahead of system implementation step. This RV-UI model system has standardized user interface which is in practical use into functional model for each process and it is designed to satisfy users' requirements and manage configuration of them through the interface which has the Kano model.

omputer and the Internet (online) services have rapidly been developed and evolved over the last 10 years. They also reduce time and costs in many parts of human life. Yet, a range of adoption and expression has been segmented as a piece of information is diversified. Particularly, while this segmentized information can be integrated according to fields, it is hard for users to aware it at a glance. Therefore, this study aims to improve and analyze programs that have been developed in a variety of ways from the existing unified design of GUI as the UIs of the Internet and programs have become accentuated recently so that it could suggest the importance of user-oriented UI designs.

This paper summarized the forming, structure and management of the Ui-Jeon(衣廛) in Joseon Dynasty, considered the change of the commercial power of the Ui-Jeon in the $18{\sim}19th$ centuries. The Ui-Jeon was established the early period of the Joseon Dynasty. The Ui-Jeon merchants organized the association named Dojung(都中) and were in business with facilities like Haenrang(行廊) and Doga(都家). The Ui-Jeon was mid-sized Si-Jeon, the licensed shop(市廛). The Ui-Jeon held the monopoly of clothes. The Ui-Jeon merchants sold and bought old clothes, sold new clothes, lent the wedding dress for a bridegroom. The Ui-Jeon paid taxes and supplied clothes, goods and sewing labor for the marriage, funeral ceremonies of the royal family. The commercial power of the Ui-Jeon was threatened by free merchants(私商) named old clothes mercants(破衣商). Finally the Ui-Jeon merchants lost the exclusive right to clothes in 1791. After that, the Ui-Jeon merchanrs appealed to the government to give them the monopoly. The Ui-Jeon merchants regained the sole right to sell Ju-ui(紬衣), one item only, but it was temporary. Separately The Ui-Jeon merchants acquired the rights to collect the sub-taxes(分稅) from free merchants.

The purpose of this study is to empirically verify how UI usability of mobile healthcare applications affects the perception of technostress and continuous use of elderly users. Through this, the effect of UI usability of mobile healthcare applications on technostress and continuous use intention was demonstrated for 199 people aged over 60. As a result, all four sub-factors of UI usability had a significant effect on technostress, and the magnitude of the influence was found to be in the order of content, process, design, and system. On the other hand, it was found that technostress had a significant effect on the intention of continued use. Through the above results, a UI design strategy that can lead to continuous use by relieving the technostress experienced by the elderly was suggested. This provides academic and practical implications for the future development and service direction of mobile healthcare applications for the elderly.
