최근 안드로이드 소프트웨어의 숫자가 날로 증가하고 있는 동시에 사용자들의 요구 수준도 함께 높아지고 있다. 이에 따라 소프트웨어의 품질을 높이기 위한 테스트 과정의 중요성이 두드러지고 있으며 안드로이드 소프트웨어는 GUI를 기반으로 하고 있기 때문에 현존하는 GUI테스트 기법들을 이에 적용시키는 다양한 연구가 진행되고 있다. GUI 테스트 기법 중 Record-Playback 기법은 사용자의 사용 흐름을 기록 후 재현하는 방식으로 테스트를 반 자동화함으로 테스트 과정에 소모되는 시간과 자원을 감소시키기 때문에 많은 분야에서 활용되고 있다. 하지만, 이 기법은 테스트 케이스 생성 시 테스터의 비효율적인 노동을 증가시키는 문제점이 발생하고 있으며, 또한 안드로이드 환경에 적용시키기 위해서 그 특성에 대한 고려가 필요하다. 이에 본 논문에서는 안드로이드 환경에 적합한 RPB 기반 테스트 케이스 생성 및 활용 방안에 대해 제안한다. 이는 소프트웨어 테스트에 소요되는 시간과 자원을 감소시켜 소프트웨어의 품질 향상에 도움이 된다.

We developed an integrative annotation program that can perform data labeling process for deep learning models in object recognition. The program utilizes the basic GUI library of Python and configures crawler functions that allow data collection in real time. Retinanet was used to implement an automatic annotation function. In addition, different data labeling formats for Pascal-VOC, YOLO and Retinanet were generated. Through the experiment of the proposed method, a domestic vehicle image dataset was built, and it is applied to Retinanet and YOLO as the training and test set. The proposed system classified the vehicle model with the accuracy of about 94%.

The paper describes implementation of three-dimensional visualization system that is to provide comprehensive meaning of the statistical prediction results on the marine casualties. Graphical User Interface (GUI) and Web based Virtual Reality (VR) technology are mainly introduced in the system development. To provide daily forecasting, time based casualty prediction model and risk level index are developed in this work. As operating test results of the system, complicated statistical meaning can be shown in the three-dimensional virtual space using simple color. In addition, daily risk levels can be shown on the bar-graph.

The paper describes on the implementation of three-dimensional visualization system that is to visualize meaning of the statistical prediction results of marine casualty with easy of understanding. Graphical User Interface(GUI) and Web based Virtual Reality (VR) technology are mainly introduced in the system development. In addition, the time based prediction models of the marine casualty and the risk level are developed to display daily situation. As operating test results of the system, it is known that complicated statistical results can be shown as simple colour in the three-dimensional virtual space.

Pressurization test is usually required in aircraft full-scale static test. There are several test conditions including pressurization of cockpit, fuselage fuel tank, air inlet duct for T-50 full-scale static test. In this paper, the test conditions, equipment, piping analysis for the pressurization test are introduced. Tank simulation test is performed to verify the validity of piping analysis and to find good tuning parameters for the pressurization channel in the servo controller. Several test setup for pressurization of T-50 test is introduced. Test article volume is filled by form, $60%{\sim}80%$ volume is reduced for the T-50 full-scale static test. Pressurization system is connected to servo controller which also controls hydraulic actuator. Load and pressure control is synchronized by using the same servo controller during T-50 test. Typical control result for pressurization test condition is shown. Pressurization tests of T-50 full-scale static test was completed successfully.

Digital cable TV(DCATV) is totally different with a existing TV which is passive, and can pick the contents anytime we want. It is very popular in many houses and we can see bright future with this. This study will show a standard that is a suitable and convenient VOD menu category for 20's through a various usability test. Moreover it will be provided new menu style and GUI through the preferences. For this, we found expected problems first through the heuristic analysis and did iterative usability test to verify and improve these problems. As a result of that, we improved errors of VOD menu structure and suggested new menu style including metaphor, colour and icon users can recognize easily. That is, VOD categories should be grouped among definite meanings. And we found using convenience is more important than new discovery of method on menu style for experienced users. This study can be not only based data when DCATV menu is renewed but also can be used as a reference data when designing other DCATV menu.

When testing various images outdoors with an infrared imaging system, it is necessary to save the tested images for comparison. In addition, after the test, it should be possible to easily connect to the PC and download the stored data. With the recent development of the memory system, it is possible to design an infrared image storage board for an outdoor test by using the eMMC memory that can be easily used in the form of an on board. In this paper, we describe the design of a portable image storage board that can easily store and download infrared images, and describe the GUI program that can connect to a PC and download the stored images.

Cluster systems have been widely used for solving problems in various application domains, and regarded as useful high performance computing resources. As the number of cluster system user is increasing, it is no less important to maintain stable operation than to improve cluster system performance. Although hardware preventive maintenance is important for keeping normal operation, the testing tool which can be used for general cluster systems during maintenance has received little attention. In this Paper, considering hardware Preventive maintenance, we suggest a testing tool for hardware of cluster system. The cluster system testing tool which is named CTS(Cluster system Test Suite) has two check routines; one for memory, and the other for NIC respectively. The CTS is designed to support the common features of general cluster systems and all the Jobs such as setting test conditions to querying the results can be done entirely within an integrated GUI environment. CTS is used as the testing tool for two kinds of cluster systems during maintenance, and the experimental results show that CTS reports useful information for cluster systems management.

The flutter/vibroacoustic characteristics can be acquired by conducting flight tests with various conditions for a long period of test. Accordingly it is indispensable to build a specially designed database system to efficiently accumulate the enormous data obtained from flight tests. Hence, T-50 Flight Test Database System(FTDS) based on MS-Access is developed to handle the flutter/vibroacoustic environment data obtained from flight tests. The developed system is structured with the items related to aircraft flight test, the tables composed of the relevant items and a relational database logically connecting the tables. The T-50 FTDS is implemented with data searching GUI(Graphic User Interface) programed with Visual Basic and Structured Query Language to make intuitive searches over the stored data. The developed system has been used for accumulating the flutter/vibroacoustic data and verifying vibroacoustic Specifications.

A simulator has been developed in order to simulate and to be used to design the pervaporation system for separating organic/water mixtures. This simulator is composed of simulation engine, which includes a modeling of pervaporation system and the numerical analysis, and Graphical User Interface(GUI), which enables us to operate the simulator more easily in the Windows environment. The structure and operation of simulator were clearly presented by demonstrating the full-scale ethanol dehydration process. The performance of simulator turned out to be fairly good through comparing the simulation results with the experimental data of ethanol dehydration pilot tests.
