The Web environment of the frontend domain is increasingly competitive to preempt the new standard of presentation layer. N-Screen, a service that enables users to seamlessly use one content in various devices in Korea, is competing for market preemption by recognizing it as a core service of the future. In the cloud computing, N-screen is a typical service type. However, most of the frontend research required for groupware in enterprise environments has been limited to responsive web design for the web and native apps for mobile. Gradually, the need for MVC design patterns is increasingly widening in enterprise environments to overcome the cultural differences of companies and to support one source multi-use strategy supporting multiple devices and development productivity. Therefore, in this study, we will analyze and design JPetStore with hybrid application design based on Spring MVC, e-government standard framework environment of next generation web standard, and provide reference model of frontend hybrid apps design in future enterprise environment.

본 작품은 학생들의 캡스톤디자인 작품이다. 본 작품은 지금까지 내려온 전래동화에 나와 엄마, 아빠가 등장할 수 있는 있도록 동화속의 캐릭터 대신 독서자의 얼굴을 교체한 작품이다. 즉, 아이와 부모가 전자기기(갤럭시탭 등)에 등록된 사진을 동화속 주인공 대신 삽입하면 동화를 읽으면서 가족간 서로의 역할을 수행하는 작품으로 아이가 동화속에 이입될 수 있고, 집중할 수 있도록 꾸민 작품이다. 본 작품의 개발은 플래시 기술을 활용하지만, 앱 형태로 제작되어 동화를 좋아하는 아이와 부모가 쉽게 접근하도록 개발되었다.

Smartphone used to be an it item for only business people and early adaptors. However, the public interest towards Smartphone has been rapidly increased and now is spreading to the everyday life in general people. Variety of applications are introduced and registered in a day, but there are not enough apps with simple and useable interface. This is because that the applications are developed only in a view from developer and designer to match the splendor design and technical skills of apps not concerning the users. Therefore this study will analyze the value in use and design trend of registered apps in apps store to recognize the importance in use and also to discuss about a plan to apply this into the apps more effectively. In order to improve the mobile app usability, this study suggest that using intuitional icon, designing easy to use app navigation. This will lead to produce clear instruction for app developers and designers with more reliable effects in the future of Smartphone world.

Mobile GUI design is changing from an existing design that emphasizes intuitive cognitive effects to an affordance design that naturally triggers users' behaviors. However, in the GUI design, the current affordance only uses some partial design elements and cannot achieve effective design, and the concept of affordance design still has confusion and uncertainty. For this reason, this paper redefines affordance by examining the concepts and types of it in the pre-research. In addition, through questioning the type of affordance, a questionnaire was designed for the GUI elements of social software. According to the results of the survey, the evaluation of the affordance of the GUI design elements was derived, and the GUI design of the social software was compared and analyzed. Then according to the deep interviews, a GUI design proposal that can effectively use affordance was proposed.

Although several industrial revolutions and technological developments have provided time for modern people, more than 75% of modern people are currently suffering from the problem of "lack of time". Therefore, in this paper, it was judged that it was necessary to improve the mobile APP service for efficient time management of modern people, and a study was conducted on the development of usability evaluation tools. First, the current status was analyzed through case studies of six time management apps with different purposes, and then usability studies were conducted to establish a total of five evaluation principles with operability, cognition, user suitability, minimization of work errors, and sharing. Based on this, a draft of the time management mobile app usability evaluation item was prepared, and a total of 44 usability evaluation tool items were derived through three Delphi surveys of design experts over 5 years and less than 10 years. As a result, intuitive screen and menu composition and user's perception of content were evaluated as the most important factors, and conclusions such as the need to improve the structure and function of the main content screen for user error prevention and usability were drawn. This study will not only contribute to improving the usability of existing time management mobile apps, but will also be used as a material for designing an integrated time management platform for efficient time management and purpose promotion in the future, and is expected to be used as an academic reference.

With the advent of experience era, the user experience has attracted much attention in all walks of life. And the importance of user experience emphasize began to be emphasized. It analyzed the interfering factors of user experience of smart phone medical APP, and evaluated their relative importance. Then it made suggestions on the priority of medical APP development and provided reference for medical APP design optimization and service quality improvement. First of all, based on the related research about user experience theory, smartphone APP user experience and mobile medical APP, it summarized the user experience elements of smartphone medical APP. Secondly, 200 subjects in the 20-40 age group who chose smartphone download experience and used medical APP were surveyed to rate the effect of 18 factors. The results show that the factors such as product resources, medical advertising recommendations, doctor-patient interaction, emotional pleasure, easy to learn, and other factors have a significant impact on users' good experience when using app.

Currently, people are paying more attention to smart home businesses. Therefore, the research on smart home system is becoming important. Smart Home App, which is an important component of smart home system, needs to consider the development of evaluation indicators for usability. In this regard, this paper takes smart home App as the object to develop the usability evaluation indicators of smart home App design. For this purpose, this study performed three rounds of survey by using the Delphi method. In the first round, 8 suitable areas were selected by collecting opinions from experts and analyzing the Content Validity Ratio, which was derived from literature review. Based on the results of the first survey, a total of 38 evaluation items were collected through prior research and user interview surveys. For the 38 collected evaluation items, 27 evaluation items have been selected by analyzing Average Value, Standard Deviation, Content Validity Ratio, Consultation and Convergence in the second and third rounds. The result of this study can be used as a guideline when evaluating the usability of smart home App design.
