In this study, the safety aspects were studied by comparing the charge control characteristics of the two vehicles when a failure occurs between the OBC including the charging port or the charging door module (CDM) during slow charging using the In Cable Control Box (ICCB) for a long time.When the AC terminal was momentarily disconnected during charging, the Model-3 vehicle was charged normally if the AC circuit was disconnected up to three times, and the charging control was stopped when the number of disconnects reached four times. However, in the Ioniq-5 vehicle, charging control was normally performed when the disconnected AC circuit was normally connected regardless of the number of disconnection.

It is worth studying the Saemaul Development Undong as a science when it is increasingly gaining a global society interest. The purposes of this research are to frame the project design matrix(PDM) for the Saemaul development project and to suggest underpinning theoretical background which explains the causal relationship of the logical frame approach of the PDM. This research diagramed the driving process of Saemaul projects which indicates the stages of hierarchical logic structures in terms of inputs-activities-outputs-outcomes and goal of the projects. Then it presented governance theory, bottom-up approach, endogenous development and network theory as theoretical backgrounds of the logic model of Saemaul projects. Expected effects of this research suggest that it will be a basic study to give a standardized criteria to evaluate Saemaul and ODA projects to raise the effectiveness of ODA projects, even though it needs more studies to secure the validity of the PDM and to get a generalization of the theory.

중층트롤어구의 수심 제어는 시스템의 복잡성과 비선형성 등으로 인하여 아직까지 자동화되지 않았다. 본 연구에서는 회류수조에서 작동되는 모형 트롤어구의 예망시스템을 제작하였으며, 이 시스템의 수심을 자동으로 제어하기 위해서 퍼지논리를 이용한 제어시스템을 구성하여 성능을 실험하였다. 제어시스템의 수심제어 규칙은 숙련된 항해사나 선장이 실제 조업에서 어구의 수심을 제어하기 위해 사용하는 지식을 제어규칙화 한 것과 모형실험에 적합하도록 수정한 규칙 두 가지를 사용하였다. 제어계의 성능은 예망속도를 일정히 유지하면서 목표수심을 스텝상으로 변경시켰을 때의 추종성능 실험과 목표수심을 일정히 유지하면서 예망속도를 변경시켰을 때의 보상성능을 실험을 통하여 분석하였다. 1. 본 연구에서 제안된 두 가지 제어기는 모두 일정한 유속(0.35m/s)에서 스텝상의 목표수심 변경에대해서 빠른 추종성능을 나타내었다. 특히 수정된 제어규칙에서는 모형 어구의 수십을 보다 안정되게 제어하였다. 2. 예망속도(유속)를 변화시켜 어구저항을 증감시킨 실험에서도 두 제어기는 비교적 양호한 보상 성능을 나타내었는데, 실제 조업에서 사용하는 규칙은 작은 외란에도 빨리 반응하였으며, 수정된 제어규칙은 수심편차가 어느 정도 커져야 제어동작을 하였다. 3. 본 연구에서 제작된 모형트롤시스템은 실물트롤 시스템의 운동 특성과 거의 일치하였고, 또한 설계된 제어기는 양호한 제어성능을 나타내어 모형실험을 통한 시스템의 해석과 실물 트롤시스템에 적용가능성이 높은 제어계의 설계가 가능하였다

One of the main purposes of architectural history is the analysis of existing designs in order to find laws and orders of certain types, while space planning emphasizes the generation of design. In this study, relational space planning methodology is used to generate Chosun upper-class housing prototypes based on 'Yaejae' logic model. During the Chosun Dynasty era in Korea, Confucianism was the ruling ideology for its society. The patio type house was the main upper-class housing type during the Chosun Dynasty, and it can be viewed that space planning was heavily influenced by the law of 'Yaejae' in Confucianism. The logic of 'Yaejae' can be interpreted as relationships between spaces. Relational space planning methodology that reasons through constraint propagation is used to generate prototypes. Prototypes are compared in order to verify actual applications of the logic into space planning.
