Software maintenance activities have always been important issues in many domains of the software industry. In order to help to resolve this issue, software modularization approaches have been studied to build adequate modules with high cohesion and low coupling; such modular structures can help the comprehension and maintenance of complex systems. In this paper, we propose a GUI-based automated approach for software modularization based on GUI structure analysis. GUI is a principal manner to allow users to access the overall functionalities of a software system; in particular, GUI is closely related to software functionalities, which makes it a promising tool to identify and understand the entire software system. We also implement a software tool to support our approach and evaluate it with a case study using an open source software.

Recently, the most mobile application software developers are being faced by short developing time (fast time-to-market), various requirements and requirement changes. In order to overcome the environment, developer should support user friendly GUI and assure the quality from the early developing process using GUI test method. This paper proposes a test method and tool for mobile software GUI, which reduces test time and supports comfortable test environment by user oriented UI design. We implemented a tool based on test scenarios based image flow for high testing accuracy and test case reusability. And the results show the characteristics of the method compared to the existing tools.

In these days GUI components are recognized as the important driving elements to the successful software development. Thus they must be verified. In practice, however, GUI testing for verifying the GUI components needs lots of time and high costs. Test automation for GUI testing is a promising solution to save those expenses. In this paper, we discuss some issues considered to perform GUI testing and suggest a new method that improve the GUI test case generation method based on our previous 'record & playback' approach. For this, we suggest the event generation method using the 'spy' technique and the scenario generation method that generates effectively a lot of scenarios with the generated events. In turn we describe how to create GUI test cases from the generated scenarios.

This study introduces MATLAB Graphical User Interface (GUI)-based software to monitor ionospheric disturbances. This software detects ionospheric disturbances using Global Positioning System (GPS) and Global Navigation Satellite System (GLONASS) measurements, and estimates a location of the disturbance source through the detected disturbance. In addition, this software includes a sky plot making function and frequency analysis function through wavelet transform. To evaluate the performance of the developed software, data of 2011 Tohoku earthquake in Japan were analyzed by using the software. The analysis results verified that the ionospheric disturbances were detected through GPS and GLONASS measurements, and the location of the disturbance source was estimated through the detected disturbance.

In order to enhance the productivity of mobile and develop reliable software, the test of mobile application software should be required absolutely. The most important way to communicate to users has been used to GUI. But GUI test method in mobile has no the test automation system except manual test by checklist. In this paper we present a test method and tool by image flow to reduce the time required and finds out errors to GUI, by carrying out the study on automatic GUI testing tool based on image flow to GUI test of mobile application.

Measurement is used to improve software process and to help calculating software quality. It makes software project to be control and help producing software. Measuring software scale becomes important target in software development. LOC is used to measure the size intentioned aspect and function point is used to measure the function intentioned aspect. This paper discusses measurement method using function point, which fullows proposed rule, and degree of GUI (Graphical User Interface) accesses achieved by applying this measurement to web page. Applying proposed rules to web pages (specially that use much GUI such as shopping mall or auction site), there is advantage that calculate site changes on numerical value by measuring GUI degree when do site administration or update.

In this paper, multi-GNSS network RTK MAC correction generation software developed based on MATLAB GUI is introduced. The software was developed as a post-processing software based on simulation data to evaluate the feasibility of an algorithm for generating correction for multi-GNSS including GPS, GLONASS, and Galileo. As a result of software operation, network RTK correction for each system of multi-GNSS is output in MATLAB file format. In this paper, to evaluate the performance of the developed software, the residual error was analyzed after applying the correction generated through the software to the user. As a result of the analysis, it was confirmed that effective network RTK correction could be generated by confirming that the residual errors of users were maintained at 10 cm or less.

Graphic User Interface(GUI) of mobile application is the working environment exchanging informations and almost functions on mobile are operated by it. In order to increase the productivity and to develop reliable mobile software, GUI test is absolutely needed. In this paper, we introduce the scenario based GUI test method and automatic tool(MoGuT). The MoGuT can detect the functional faults using scenarios and operate in SKVM environment.

In this study, PC-based slicing machine and driving software were constructed for the purpose of automation of semi-conductor cutting process. The biggest feature of software is variation of parameter and include data base, signal monitoring, error report, corresponding action or automatic motion planing. Parameters were drawn and algorithms were developed to make software by GUI interface. The cutting experiment was done for sampled wafer to see the effectiveness of the soft automation. From the experimented and implemented results, it is shown that parameters for automation of slicing process could be drawn, then its algorithms constructed. It could be considered what is the merit of this slicing machine by comparing the PC-based and the NC-based.

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.
