Artificial intelligence is becoming a global hot topic and is being actively applied in various industrial fields. Not only is artificial intelligence being applied to industrial sites in an on-premises method, but cloud-based artificial intelligence platforms are expanding into "as a service" type. The purpose of this study is to develop and verify a measurement tool for an evaluation framework for the adoption of a cloud-based artificial intelligence platform and test the interrelationships of evaluation variables. To achieve this purpose, empirical testing was conducted to verify the hypothesis using an expanded technology acceptance model, and factors affecting the intention to adopt a cloud-based artificial intelligence platform were analyzed. The results of this study are intended to increase user awareness of cloud-based artificial intelligence platforms and help various industries adopt them through the evaluation framework.

This paper propose methods to implement operation of underfrequency relay using EMTP MODELS. Simulation results shows the operation of the frequency relay as well as the status of generator and power systems. The simulation method described in this paper can thus be employed as a very useful tool in the testing of frequency relay algorithms and/or in the development of any new ones.

Analysis of squeal noise generated during brake operation is an important task for the improvement of brake noise prob-lem. By the use of measuring instrument and techniques, test and evaluation process are to be developed systematically in quantitative analysis. The cost far test and evaluation 7an be reduced, and the technical power can be raised by the devel- oped system.

The microprogram is the key technology of the implementation of the processor's control unit. But the coding and testing it is the most tedious process in the developing a new computer system. We developed the conversational micro architecture simulator(C-MAS) in order to use it as a microprogram development tool and a run time analyzer of the microprogram. We discuss the hardware description language(HDL) for a smulation, the design constraints of the C-MAS, and the user interface of it in this paper. We used the C language as the description language, and developed it on the berkeley UNIX4.2.

To develop domestic IGCC gasification technology, a gasification test bed with a capacity of 20 tons/day has been designed. The main components of the test bed designed are a coal pulverizing and feeding facility, a gasifier, a syngas cooler, a gas treatment unit, oxygen and nitrogen tanks, and flare stack. For wide applications to the development of advanced coal gasification technology, many special functions have been given to it such as syngas recirculation, char recirculation, and multiple stage gasification. The test bed will be used for testing the characteristics of various types of coals, deriving optimum conditions for efficient gasifier operation and trouble shooting for the Korea IGCC demonstration plant. It will also be applied as a useful tool to develop scale-up design technology of IGCC and proceed to commercialization.

Research on the development of CNG dedicated engine that has important meaning both as a clean fuel and an alterna- tive energy to reduce the exhaust emission from diesel engine are actively going on these days. In this study, in order to present the direction and application of CNG engine, we tested the CNG engine performance experimented by changing the parameters such as ignition timing, equivalent ratio. The engine performance experimented by changing the parameters such as ignition timing, equivalent ratio. The engine performance and exhaust emission were measured by engine performance model at maximum load condition with increasing the rpm in the range of 1,000∼2,200rpm. Also, the testing engine was heavy-duty CNG dedicated engine with displacement of 11,050cc.

In view of reliability assessment, the failure mode analysis by performance tests for machine tools is researched in this study. First, the error analysis with circular movement test data is studied. The various errors and their origins are analyzed by the error equations and then related parts and failure modes are investigated. Second, This paper deals with analysis of vibration testing for machine tools spindle. The various frequency components are classified by fourier transform and order analysis. The simple measuring devices and web-based analysis programs for each test are also developed.

Fuzzing is widely used as a testing tool to identify vulnerabilities in software programs. Although AFL++ has emerged to facilitate the integration and development of many fuzzers, there are still numerous advance fuzzing technologies that have not yet been incorporated. Among these, we have integrated state-of-the-art directed-based fuzzing techniques into AFL++ to operate in QEMU mode.

최근 소프트웨어가 사회에서 하는 일이 점점 더 증가함에 따라 소프트웨어의 개발비용도 함께 증가하고 있다. 소프트웨어의 개발비용 중 에러를 찾아내는 소프트웨어 테스팅이 상당한 부분을 차지하고 있는데 테스팅에 소요되는 비용 때문에 테스팅을 등한시 하는 경우가 많다. 그럼에도 불구하고 소프트웨어의 기능 추가나 변경이 이루어질 때마다 테스트를 진행하여야 소프트웨어의 에러를 최소화할 수 있다. 하지만 개발이 진행될수록 소요되는 비용이 증가하는 경우가 많아 실제 소프트웨어 개발에선 개발 기한이 다가올수록 회귀 테스트를 기피하게 된다. 본 논문에서는 이러한 문제를 해결하기 위해 소프트웨어의 개발을 진행하면서 형상관리를 통해 소프트웨어의 변경이 있을 때마다 회귀 테스트를 자동으로 수행해주는 도구를 제안한다.

소프트웨어는 의도하지 않은 결함을 반드시 가지고 있다. 이러한 결함을 찾아내기 위해서는 테스트가 반드시 진행 되어야 한다. 수많은 소프트웨어 제품들이 나오게 되면서 테스팅 기법도 표준화 되어 가고 있다. 이러한 테스팅 기법들을 현업에 종사하는 테스터가 사용시 많은 시간과 비용이 들게 된다. 이를 좀더 효과적으로 테스트 하여 시간과 비용을 줄일 수 있는 방안을 찾고자 하는 것이 본 논문의 목적이다. 실행 가능한(eXecutable), 확장된(eXtended), X-internet 환경을 구축하는 UI(User Interface)개발 도구를 개발함에 있어 제품의 안정성을 향상 시키기 위하여 기존의 소프트웨어 테스팅 기법을 이용한 테스팅 방법론을 연구하고자 한다.
