칩의 집적도에 비례하여 설계검증 및 칩 제작 후의 결함점검은 갈수록 어려워지며 이러한 테스트 문제의 원초적 해결을 위하여 다양한 테스트설계 기술이 널리 개발되고 있다. 상위 수준의 테스트설계에서는 회로의 기능에 대해서는 알 수 있으나 구조에 대해서는 알 수 없고, 하위 수준의 테스트설계에서는 회로의 구조를 알 수 있으나 기능은 알 수 없다. 따라서 테스트 설계는 기능을 기술하는 상위 수준에서부터 고려되어 하위 게이트수준에서 스캔플립플롭을 선택하여야 최적화된 성능을 얻을 수 있다. 본 논문에서는 테스트용이도를 증진시키기 위해, 상위수준의 기능정보에 대해서는 테스트점을 삽입하여 제어흐름(control flow)을 변경하고, 상위 수준의 합성 후에 하위 수준에서 스캔플립플롭을 선택하여 다시 합성하는 상위.하위 수준에서 통합된 테스트 합성 기술을 제안한다. 실험결과 통합된 테스트 합성 기술이 대부분의 벤치마크 회로에서 높은 고장검출율을 보여주고 있다.

This study was undertaken to determine the correlation between β-amyloid, serum lipid levels, and cognitive function in the elderly with mild Alzheimer's dementia. The study was conducted in December 2018, enrolling 45 elderly people with mild Alzheimer's disease. Blood analysis measured the β-amyloid and serum lipid levels, and cognitive function was measured using MMSE-K. The correlation between β-amyloid, serum lipid levels and cognitive function was determined using Pearson's correlation analysis. A significantly negative correlation was observed between the β-amyloid level and cognitive function (p<0.05). Furthermore, serum lipid levels and cognitive function also revealed a significantly negative correlation between TC and LDL levels (p<0.05). These results indicate that increasing levels of β-amyloid, TC, and LDL augments a negative correlation that decreases the cognitive function, signifying that management of pathologic factors related to dementia is important for the prevention and improvement of cognitive function in dementia patients.

This paper is a study on the method to derive the functional level required for autonomous unmanned ground vehicle, one of the defense robots. Conventional weapon systems are not significantly affected by the operating environment, while defense robots exhibit different performance depending on the operating environment, even if they are on the same platform. If the performance of defense robot is different depending on operational environment, results of mission performance will be vary significantly. Therefore, it is necessary to clarify the level of function required by the military in order to research and develop most optimal defense robots. In this thesis, we propose a method to derive the required function level of unmanned ground vehicles, focusing on autonomous driving, one of the most vital functions of defense robots. Our results showed that the autonomous driving function depending intervention levels and evaluated functional sensitivity for autonomous driving of the unmanned vehicle using climate and topography as variables.

While the Earthquake Resistant Design Part of Korean Roadway Bridge Design Code provides design procedures for the No Collapse Requirement, requirements for the Serviceability Limit State are not clearly provided. The basic design method to meet the No Collapse Requirement is the spectrum analysis method using response modification factors and the Serviceability Limit State is determined by both the importance factor and the response modification factor applied in the design procedure. The importance factor can be simply applied according to the bridge importance category, however, in moderate/low seismic regions the application of the response modification factor may bring different result according to design conditions. In this study, for a typical bridge in the moderate/low seismic regions, determination procedures for the Serviceability Limit State are reviewed by carrying out earthquake resistant design and supplementary provisions for the Earthquake Resistant Design Part are identified based on the study results.

The purpose of this study is to investigate the relationship between cognitive levels and achievement of science process skills. A science laboratory process skills test based on optional instrument of the SISS was administered to a sample of 162 students in the 8th grade. Practical assessment tasks consisted of the contents about acid, base, density, and a property of cobalt chloride. The format of this practical test was the station type that students had to conduct a short activity. Science process skills included three sub-skills which were categorized as designing, performing, and reasoning. As cognitive levels develop from concrete operational stage to transition stage and formal operational stage. total scores of science process skills and mean scores of sub-skills were significantly increased. Regardless of cognitive levels. all students were more successful on performing than designing or reasoning. In case of being controlled cognitive levels, gender differences and area differences were not detected in achievement of science process skills. According to these results. there was a strong relationship between cognitive levels and achievement of science process skills by practical assessment. This study implies that considering student's cognitive levels is very important for improving science process skills.

시스템을 결정하는 품질 요소에는 여러 가지가 있으나 그 중에서도 유지보수성(Maintainability)이 높은 시스템을 만드는 것은 쉬운 일이 아니다. 또한 유지보수성이 높은 시스템인지 여부를 시스템 개발이 완료 전에 측정하는 것도 어려운 문제이다. 모든 품질요소가 그렇겠지만 시스템을 구성하는 소프트웨어 아키텍처 수준에서 시스템의 품질을 명확히 측정해내지 못하고 시스템 개발 이후에 측정한다면 품질 향상을 위한 시스템 수정은 생각할 수도 없는 문제가 될 것이다. 이 논문은 유지보수성 중에서도 가장 중요한 기능확장성(Extensibility), 즉 기존 시스템에서 신규 서비스를 추가하려 할 때 기존의 서비스에 영향을 미치지 않으면서 비용 및 기간을 최소화하여 새로운 기능을 추가할 수 있는 품질 속성을 소프트웨어 아키텍처 수준에서 비교하는 방법을 정의하여 제시한다. 본 논문에서는 소프트웨어 아키텍처 중에서도 기능확장성에 가장 큰 영향을 미치는 모듈 뷰를 기준으로 기능확장성을 측정할 갓이나 모듈 내부의 변경을 통한 기능확장성은 고려하지 않고 새로운 모듈의 추가로 인한 기능확장성을 고려하였다. 본 논문은 기 수립된 소프트웨어 아키텍처의 모듈 뷰가 가지는 고유한 기능확장성을 측정하는 함수를 제시하고 여기에 새로운 모듈이 추가될 매 변화한 소프트웨어 아키텍처의 기능확장 effort 함수를 제시한다. 이 두 함수를 통해 두 개의 대안 소프트웨어 아키텍처 모듈 뷰에서 어떤 것이 더 기능확장성이 있는지 판단할 수 있게 한다. 우리는 이를 검증하기 위해서 기능확장성이 좋다고 제시되고 있는 디자인 패턴(계층패턴과 Broker 패턴)을 통해 본 논문의 이론을 정립하고 그 효용성을 입증하였다. 따라서 소프트웨어 아키텍처 수준에서 기능확장성이 얼마나 가능한지 서로 비교 가능한 수치를 제시하였고 이 수치를 통해 실제 개발이 완료되기 전 시점에 시스템의 기능확장성을 명백히 측정할 수 있게 하여 시스템 기능 확장에 들어가는 많은 비용을 줄일 수 있다는 것을 보여준다.
