As the necessity of maker education is being emphasized and the app generation is now entering school, expectations concerning the impact of app development education are rising in the field of education. The introduction and rise in popularity of a new type of education, such as app development education, requires a change in attitude among teachers. Therefore, this study focused on the concerns of in-service teachers regarding app development education by applying the Concerns-Based Adoption Model (CBAM) of Hall and Hord (2015). For this purpose, the data was collected from 23 in-service teachers who attended a short teacher training session that introduced app development training. The data was converted to the relative intensity based on the stage of concerns questionnaire (SoCQ) scoring device and was expressed as the SoCQ profile. The results of the survey concerning app development education showed that the stage 0 concern (unconcerned) was reported most frequently by teachers and the stage 4 concern (consequence) was reported least frequently. This kind of result, which is typical at the beginning of the introduction of a new education program, indicates that teachers recognize app development education but do not have sufficient information regarding it. Qualitative results also showed that teachers understand the educational possibilities of app development education, but they were worried about the difficulties expected to be applied in the field. Based on these results, we suggest that more detailed information on app development education be provided through teacher training.

In this paper, we propose an app application for classifying Korean food images and providing information related to Korean food. App Application consists of Flask server, Database (Mysql), and Python deep learning modules. Using the VGG16 model, 150 images of Korean foods are classified. If there is an internet environment, anyone can easily get information about Korean food anytime, anywhere with a single photo.

Mobile devices diffusion begins by the iPhone and spreads by the Android. A widely used mobile devices is Smartphone(iPhone, Android, Bada, WindowPhone7, BlackBerry, etc) and Tablet(iPad, Android). In the past, we have developed a dedicated application for device. But, Now we must develop a application by considering the characteristics of the operating system. Accordingly, many problems occurred and other developmet methods have emerged. In this paper, we learn about MobileHybridApp development tool-oriented One Source Multi Use-and compare the differences, propose a method to develop context-sensitive.

Real estate brokerage app service is an emerging online-to-offline (O2O) business model. This study analyze the relationship between the satisfaction and reuse of real estate app services through a survey of experienced users of the application. The results show that "ease of use" and "usefulness" of the online app service positively affect customer satisfaction and eventually affects reuse. Moreover, ease of use and usefulness of the offline brokerage introduced by the application positively affects customer satisfaction and eventually affects reuse too. One meaningful finding is the stronger impact of usefulness on customer satisfaction than that of ease of use in both online and offline situations. This finding implies that the value of usefulness is bigger than that of ease of use because of users who purposely use the application to find relevant real estates. The effect of online customer satisfaction on reuse is slightly higher than that of offline. This finding suggests that need to develop a strategy for online applications that focuses on enhancing the usefulness of real estate brokerage app services in the O2O market.

Purpose: The COVID-19 pandemic has changed how healthcare is delivered worldwide and has affected the environment of the healthcare. Physical therapy in traditional healthcare systems can be difficult in unusual circumstances, such as the COVID-19 pandemic. Tele-physical therapy, defined as "the delivery of the physical therapy at a distance using electronic information and telecommunication technologies," will be a solution for this healthcare crisis. Thus, in this study, we proposed a mobile application for tele-physical therapy. Methods: This study used the Chrome Browser version 83.0.4 based on the Windows 10 64Bit operating system to use the App Inventor. To operate the mobile application, we used the Samsung Galaxy Note 9. The design of the mobile application was based on the review of a system used in the physical therapy department. Results: The graphical user interface (GUI) of the mobile application was displayed on three screens: selecting a painful joint (1st screen of the GUI); selecting a painful movement of the joint (2nd screen of the GUI); a self-manual therapy method and movie (3rd screen of the GUI). The proposed mobile application showed the stable repeatability of the self-manual therapy movie. Conclusion: The results of this study demonstrated that the proposed mobile application using the App Inventor for android will be able to create easy to use and reliable tele-physical therapy.

Virtualization lacks capabilities for enabling the application to scale efficiently because of new applications components which are raised to be configured on demand. In this paper, we propose an architecture that affords mobile app based on nomadic smartphone using not only mobile cloud computing-cloudlet architecture but also a dedicated platform that relies on using virtual private mobile networks to provide reliable connectivity through Long Term Evolution (LTE) wireless communication. The design architecture lies with how the cloudlet host discovers service and sends out the cloudlet IP and port while locating the user mobile device. We demonstrate the effectiveness of the proposed architecture by implementing an android application responsible of real time analysis by using a vehicle to applications smart phones interface approach that considers the smartphones to act as a remote users which passes driver inputs and delivers outputs from external applications.

The purpose of this study is to introduce the concepts of smartphone and app, to review the theoretical researches and the representative service examples in academic libraries' mobile services based on smartphone apps, and to propose the proper mobile services methods based on smartphone apps in academic libraries of Korea. The ways for mobile app services in academic libraries are like these: 1) Libraries need to prepare the hybrid service system based on the combination of mobile web and app for smartphone. 2) Libraries have the guidelines for choosing apps which are applied to library services. 3) Libraries develop the apps for library marketing and education services and make use of existed apps to their own services. 4) Smartphone application bibliography service(Appography service) needs to be developed and serviced as an academic library service field.

Since only one application has monopoly on LCD device of the mobile device in Android platform, the user can not see two screens together displayed by two applications running simultaneously. In this paper, a dual-app has been defined as two mobile applications running on each device of a pair of two mobile devices and DSAP or Dual Screen Android Platform has been implemented. DSAP does remote-execution of the peer application of a dual-app on the peer mobile device when either application of the dual-app starts to run and supports communication of the pair app over the network. This paper describes details of design and implementation of DSAP and shows a sample case utilizing DSAP.
