GUI program for analyzing directional spectrum waves is introduced in this paper Basically, MLM (Maximum Likelihood Method) was used for this program which was additionally consisted of performing spectral and time domain analysis for two dimensional irregular waves. Moreover, the directionality of directional spectrum waves generated by single summation and double summation method was investigated based on MLM. The directionality from each summation method has good agreement compared with that of target wave spreading function in the case of single wide directional spectrum waves. In addition to this, the resolution of directionality in double summation method was investigated as introducing coherence function between each wave component

One of the main noise sources in cabin onboard ships is HVAC system. Up to now, the HVAC system designer manually calculates the HVAC system noise, or uses the program that is generally based on text user interface. In such a case, it is difficult to use the program and also to obtain the flow induced noise. In this study, the HVAC noise analysis program has been developed, which is based on GUI user interface that include 3.D modelling and model modification modules. For calculation of the insertion loss of HVAC system elements, NEBB experimental data and plane wave theory are used. And in order to obtain the flow rate information in each HVAC elements which is used to calculate the flow induced noise calculation, Global Converging Newton-Rapson Method is used.

In this paper, we proposed the DS-SS modem-based communication system for long distance wireless-transmission. The module we designed in this approach contained both convolution encoder and gold-code generator, which aimed at error correcting, T-DES encryption algorithm and spread-spectrum as well. It embodied PC-based GUI program in order to control the such command signal as data transceiver. This program also used to control the specific FPGA/MCU which is able to verify and interface to the modem. We demonstrated the communication system to verify its proper operation by using GUI program and designed hardware. A set of experiments are conducted and as a result, proposed communication system is well operated as the design specification.

It is useful to have a quick analysis program in early design process for feasibility studies of composite cylinder because it takes long time and is not cost effective by commercial programs. In this paper, a GUI program is developed to calculate the stress distribution in a fast manner with the properties, the orientation angle and the stacking sequence of composite material using LabVIEW. The stress distributions of an autofrettaged cylinder and a composite cylinder with internal pressure are compared with the results by MSC Nastran/patran. The stress distribution of steel/composite cylinder is compared with the values of existing studies, and is proved. Furthermore, by calculating the stress distribution of an autofrettaged steel/composite cylinder, the stress distribution is estimated, and the program will be useful in an early design phase for feasibility studies.

In this paper, we propose and develop a test automation program tool that automates GUI based testing using black box testing technique in Windows environment. The main features of the proposed test automation program tool are as follows. First, an error condition is designated as an image, a screen is captured for each test step, and an error message is detected through comparison of image similarity. Second, the proposed system supports various setting options such as event waiting time during execution and coordinate increment value between each test step. Such black box test automation research was common in environments such as Android and Web, but not in Windows environment. The results of performance evaluation show that the proposed system performs GUI test automation as an image comparison module and confirms that the test is performed normally by confirming process status and error image detection.

Recently, as disasters caused by weather such as heavy rains have increased, interests in forecasting weather and disasters using radars have been increasing, and related studies have also been actively performed. As the Ministry of Environment(ME) has established and operated a radar network on a national scale, utilization of radars has been emphasized. However, persons in charge and researchers, who want to use the data from radars need to understand characteristics of the radar data and are also experiencing a lot of trials and errors when converting and calibrating the radar data from Universal Format(UF) files. Hence, this study developed a Radar Display and Analysis Program(RaDAP) based on Graphic User Interface(GUI) using the Java Programming Language in order for UF-type radar data to be generated in an ASCII-formatted image file and text file. The developed program can derive desired radar rainfall data and minimize the time required to perform its analysis. Therefore, it is expected that this program will contribute to enhancing the utilization of radar data in various fields.

최근 스마트폰, 게임, 자동차 인포테인먼트 등 많은 애플리케이션이 GUI 기반으로 제작된다. "새싹"은 영어가 약한 프로그래밍 초심자를 위한 한글 프로그래밍 언어이다. 하지만 "새싹"은 아직 한글 GUI 라이브러리는 지원하지 않는다. 따라서 본 논문은 한글 프로그래밍 언어인 "새싹"을 위한 한글 GUI API를 제안하고자 한다. 그리고 "새싹"을 이용한 간단한 계산기 GUI 프로그램 예제를 통해 프로그램을 구현한다. 그 결과 정상적으로 작동하는 것을 확인하였다.

A pre-processing program based on the OOP(object-oriented programming) concept has been developed. The program consists of the input of a 2D or 3D flow problem to a CFD program by means of an user-friendly interface and the subsequent transformation of this input into a form suitable for the solver(PowerCFD) using unstructured cell-centered method. User-friendly GUI(graphic user interface) has been built on the base of MFC(Microsoft Foundation Class). The program is organized as modules by classes based on VTK(Visualization ToolKit)-library, and these classes are made to function through inheritance and cooperation which is an important and valuable concept of object-oriented programming. The major functions of this program are introduced and demonstrated, which include mesh generation, boundary settings, solver settings, generation of grid connectivity and geometric data etc.

In the "digitalized" world of new media, visual designer are increasingly enlarging their roles in desighing interaction products. However, the concepts and their methods of the interaction design have not been well established in the design community yet. The reason is attributed to the fact that designing interaction products requires two way communication between the products and final users. whereas traditional graphic design counts only on one way communication. This study emphasizes GUI design should aim at improving the usability of products which helps users quickly learn about the products and easily use them. The usability of GUI design significantly improved by securing logical rationality helps designers communicate and collaborate with program engineers and other product developers. To explain how designers can effectively communicate with program engineers and other product participants in the design process, a model of design collaboration is provided in this study. Based on the model, the study deals with the principles and methods of visual interaction, the formulation of specification system, testing design usability, and design evaluation. The study concludes that GUI designers must ensure logical rationality and the cognitive approach of visual language. Because it improves the usability of products. It also becomes an objective tool for communicating and collaborationg with engineers and the other participants in the design process.

In this study, a simple, efficient, user-based program called SCAR was developed for evaluating the sliding and collapse of artificial reefs due to hydrodynamic forces in ocean environments. SCAR was developed by applying Delphi code and a Graphical User Interface (GUI) based on the Morison formula for evaluating and analyzing the stability of artificial reefs. SCAR can be applied widely for design and stability evaluation of fishery structures (such as artificial reefs or other underwater structures) in undergraduate and graduate courses and by experts in the field.
