전기실험 관련 인공과학실험실에서의 도구지식의 표현 및 추론
차상철(Sang-Cheol Cha),변영태(Young-Tae Byun) 한국정보과학회 1998 한국정보과학회 학술발표논문집 Vol.25 No.2Ⅱ
전기실험 관련 인공과학 실험실은 중 · 고등학교 교과과정의 전기실험을 중심으로 한 임의의 모의 실험을 컴퓨터 상에서 가상적으로 진행 할 수 있도록 한 기존의 인공화학실험실에 기반한 시스템이다. 본 논문에서는 실험 진행을 위해 사용되는 도구 지식을 구조적으로 표현하였으며 실험 진행을 위한 도구간의 공간관계를 정의하였다. 그리고 실험의 전체상태를 나타내는 실험실 상황판의 도구간 관계정보를 통해 생성되는 계산 모델을 설계하였다. 계산 모델은 추론 진행의 조건이 되는 도구의 속성값을 결정하며, 이를 통해 추론을 효율적으로 진행 할 수 있다.

항전 비행운용프로그램 검증을 위한 단일 PC 기반 소프트웨어 시험환경 SW 설계
차상철(Sang-Cheol Cha),이두환(Du-Hwan Lee),김정열(Jeong-Yeol Kim) 한국항공우주학회 2018 韓國航空宇宙學會誌 Vol.46 No.11
항공전자 비행운용프로그램은 임무컴퓨터에서 실행되면서 각종 항전장비와의 연동을 통해 운용된다. 비행운용프로그램을 검증하기 위해서는 임무컴퓨터와 연동하는 실장비가 탑재된 SIL 또는 STE가 필수적이나 일반적으로 특정 항공기 체계개발 시 사용되는 SIL은 OEP 개발 일정과 상당 부분 중첩되므로 OFP 개발과정 후반부 또는 SW 통합 시점에 SIL이 개발자에게 제공되며 개발과정 중 개발자가 SW를 검증하기 위한 도구가 제공되지 않는 경우가 많다. 대부분의 경우 SIL은 한 세트만 제작하기 때문에 다수의 개발자가 하나의 SIL을 이용해서 SW 검증을 해야 하므로 시험단계에서 병목현상이 발생하 수밖에 없어 개발 일정 준수에 위험요소로 작용한다. 본 논문에서는 실장비가 탑재된 SIL 또는 STE 대신 개발자 PC와 임무컴퓨터만을 이용하여 OFP 기능을 검증할 수 있는 STE SW 설계에 대해 기술한다. Avionics OFP runs on the mission computer and can be operated by interacting with several avionics equipments. In order to verify OFP SW, SIL having real avionics equipments or models is absolutely necessary. Therefore in many cases SIL is implemented concurrently with OFP developing, and only one SIL is provided to developers. So developers sometimes need an alternative to SIL for verifying requirements in the middle of development process. In this paper, we propose a single PC based STE SW that simulates interworking equipments and verifies OFP in a single PC environment without actual interworking equipments or SIL HW interfaces.

무기체계 SW 개발 전반에 대한 규정인 방위사업청의 무기체계 SW 개발 및 관리 매뉴얼이 개정될 때마다 SW 신뢰성 및 품질향상을 위해 SW 신뢰성 시험의 수준과 범위를 상향하는 방향으로 변경됨에 따라 SW 신뢰성 시험은 SW 개발자에게 큰 부담이 되고 있다. 특히 동적시험은 무기체계 SW를 구현하는데 필요한 일정과 인력에 육박할 정도의 비용이 소요되고 있으며, 1회성으로 그치지 않고 소스코드 형상이 변경될 때마다 수행해야 한다. 본 논문에서는 동적시험 도구인 VectorCast를 이용하여 동적시험을 최초 1회 수행한 후 소스코드 형상변경으로 인한 동적시험 회귀시험 시 사람의 개입을 최소화하여 자동으로 회귀시험을 수행하고 결과 보고서를 생성해주는 회귀시험 자동화 프로그램인 VectorCast Environment Manager 개발에 대해서 기술한다. As the weapon system SW development and management manual of the DAPA, which is the regulation for the overall weapon system SW development, is revised, the level and scope of SW reliability test are upgraded to improve the reliability and quality of SW. It is a big burden for SW developers. In particular, the dynamic test requires a schedule and manpower required to implement the weapon system SW, and should be performed every time the source code changes, not just one time. In this paper, we propose a regression test automation program(VectorCast Environment Manager) that performs a dynamic test using VectorCast, a dynamic test tool, and then performs a regression test automatically by minimizing human intervention in the regression test of dynamic test due to the change of the source code.

Objectives : The purpose of this study is to evaluate effect of The Drug-Pad Moxibustion Cauterizer for low back pain. Methods : 14 patients have low back pain for less than 3 months. All patients were only treated with The Drug-Pad Moxibustion Cauterize with the multiple heating-pad. Moxibustion treatments were operated 3times a week, total 12times. At before treatment, after treatment, we measured Visual Analogue Scale(VAS), Pain Rating Score(PRS). And we assessed body temperature(before treatment, after treatment) by D.I.T.I.. Statistical analysis was performed by using SPSS program. Result : The average score of VAS and PRS was decreased. The decrement of VAS and PRS were statistically different(p<0.05). The comparision of temperature(ΔT) was not significant statistically. Conclusions : In view of the results so far achived, we get the idea that The Drug-Pad Moxibustion Cauterize is useful to reduce low back pain.
