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.

Embedded products are becoming richer in features. Simulation tools facilitate low-costs and the efficient development of embedded systems. SID is an open source simulation software that includes a library of components for modeling hardware and software components. SID components were originally written using C/C++ and Tcl/Tk. Tcl/Tk has mainly been used for GUI simulation in the SID system. However, Tcl/Tk components are hampered by low performance, and GUI development using Tcl/Tk also has poor flexibility. Therefore, it would be desirable to use a more advanced programming language, such as Java, to provide simulations of cutting-edge products with rich graphics. Here, we describe the development of the Java Bridge Module as a middleware that will enable the use of Java Components in SID. We also extended the low-level SID API to Java. In addition, we have added classes that contain default implementations of the API. These classes are intended to ensure the compatibility and simplicity of SID components in Java.

It has always been of great importance in the electrical power system to educate an algorithm on the digital relaying, but it is difficult to educate an algorithm of a digital distance relay on power system because of exclusiveness of the relaying algorithm on power system. Therefore, we need a digital distance relay simulator, which can simulate the algorithm of the digital relaying on transmission line. In this Paper, we extract fundamental components using digital signal processing from data which are a variety of the simulated faults by EMTP. Then this simulator represents instantaneous values, ms values and symmetrical components that are calculated by fundamental components of voltages and currents. The Simulator also represents the zones of a digital distance relay and the locus of an impedance using GUI. Consequently, the developed simulator is particularly useful for understanding of the fundamental concepts of a distance relaying algorithm from a power system engineer points of view.

Simulation tools help creating a low cost and efficient development of embedded system. SID is an open source simulator software that consists library of components for modelling hardware and software components. A component can be written in C/C++ and Tcl/Tk. Currently, the SID simulation toolkit only provides support for C++ and Tcl/Tk. Tcl/Tk is used to write GUI-based components. However, we have observed that Tcl/Tk components cause slow simulation response because Tcl/Tk is a script language. It is not proper for developing the cutting-edge products with rich graphics. Therefore, in this paper, we suggest Java to a new language for GUI components in SID by developing a bridge module for SID to interworking with Java components.

This study conducted an actual condition survey with users in order to examine the Graphic User Interface (GUI) design appearing in fast food Digital Information Display (DID). Selecting four restaurants with high sales in the hamburger industry in 2017, including Lotteria, McDonald's, Burger King, and Mom's Touch, based on this, this study investigated and analyzed GUI visual components appearing in DID, including layout, character, color, graphics, and videos based on this. As a result, this study could propose a design plan providing users with the layout that can be clearly and neatly divided, characters attracting attention with high readability, colors with high visibility, graphics attract interest, and videos with various contents, rather than a complex approach for efficient GUI design, analyzing the environmental factors of fast food restaurants.

The most important instrument to declare oneself publicly in cyberspace is to use a homepage or website. Nowadays most of Korean as well as overseas art museums have their own websites, through which they provide consumers with essential information and strive to declare themselves publicly in cyberspace. A homepage is composed of various components and the most crucial component is the interface. The objective of this paper is to present a proposal to help get a program for efficient website management and consumer satisfaction.

A crude drug "Dang-Gui", belonging to the genus Angelica, has been used as a traditional herbal medicine in Asia. Various studies have investigated the chemical components and pharmacological activities of Dang-Gui worldwide. However, domestic research results published in Korean are undervalued in international academia due to language barriers. Therefore, it is necessary to summarize the domestic research findings systematically for greater accessibility. This review focuses on the results published in four Korean pharmaceutical journals between 1970 and 2018, which detail the botanical, phytochemical, and pharmacological properties of three Angelica species (A. gigas, A. sinensis, and A. acutiloba) used as "Dang-Gui" in Korea, China, and Japan.

21st Century is getting into Super aging society worldwide basis. Among those population, silver(aged) generation users' physical condition, such as sight, hearing and body, is getting older, especially sight ability which processes 80% of input data, it requires us studying new smartphone GUI designs convergence for the elderly. In light of this social phenomenon, this study suggests smartphone GUI designs convergence guideline for the silver generation through the research of text, icon which are basic elements of smartphone GUI with proper visual attributes. I had inferred UX designs, expert group and evaluation categories from existing papers, related books and designed some displays for the survey. I also offered this guideline with the deep survey of 101 people over 65 years old.

The purpose of this study is to develop a structural analysis system of LNG pump tower structure. The system affords to build optimized finite element model and procedure of the pump tower structure. The pump tower structure is one of the most important components of LNG (liquefied natural gas) carriers. The pump tower structure is subject to sloshing load of LNG induced by ship motion depending on filling ratio. Three typer of loading components, which are thermal, inertia and self-gravity are considered in the analysis. The finite element analysis is performed with ANSYS commercial code. The failure of each members can be evaluated of API unity and punching shear in ABS rule. The GUI is newly developed using Tcl/tk script language. All these design and analysis procedures are embedded in to the analysis system successfully.

This paper proposes a Ubiquitous Greenhouse Management System (UGMS) based on USN(Ubiquitous Sensor Network) which can be real-time monitoring and controlling of greenhouse's facilities by collecting environment and soil information with environment and soil sensors, and CCTV camera. The existing systems were controlled simply by temperature. Also, it was possible to monitor only at control room in a greenhouse. For solving problems of the exiting system, our system can remotely monitor and control greenhouse by considering environment information. The detail components are as follows. The system includes the sensor manager and the CCTV manager to gather and manage greenhouse information with soil and the environment sensors, and camera. Also the system has the greenhouse database storing greenhouse information and the greenhouse server transmitting greenhouse information to the GUI and controlling greenhouse. Finally, the GUI showing greenhouse condition to users exists in our system. To verify the executability of the UGMS, after developing the greenhouse model, we confirmed that our system could monitor and control the greenhouse condition at remote GUI by applying the UGMS's components to the model.
