도플러 효과는 혈관의 혈류속도를 측정하는데 이용된다. 대부분의 도플러 시스템은 측정위치에 대한 정보를 제공하는 펄스 도플러 시스템이다. 본 논문에서는 2차 샘플링 방식과 직렬 신호 처리를 이용한 새로운 2차원 펄스 도플러 시스템을 제안한다. 제안된 시스템은 직각 위상 검파 방식에서 동상과 $90^{\circ}$ 지연된 위상신호의 불평형성을 해결하고, 또한 직렬 신호 처리를 사용하므로서 2차원 도플러 시스템에서의 채널 간의 평형성 문제를 해결했다. The doppler effect is used for measuring the velocity of the blood flow in artery. Because of the range information, the pulsed doppler system is most commonly used. In this paper, we propose a new two-dimensional(2-D) pulsed Doppler system. Which uses second-order sampling method and serial processing. The proposed system using second-order sampling method eliminates in-phase, quadrature-phase balancing problem at demodulator of quadrature detection method. In addition, the new pulsed 2-D doppler system eliminates balancing problem of channels of 2-D doppler system because of serial processing.

In an experiment where students learn electrical and electronic theory and apply it, students have difficulty in connecting circuits. To alleviate the above difficulties, we first propose a circuit analysis service. The proposed method detects an electric device using an object detection model in which electric devices connected to a breadboard are labeled with data. To verify this, we connect to the breadboard circuit and create a custom dataset through photographs. The proposed method is divided into two processes: electric device prediction and electric device position detection. The electric device prediction model was compared using five object detection models, and the Faster R-CNN model had the best prediction performance. The electrical device position detector extracts features from the object detection model through transition learning to predict two coordinates (x1, y1), (x2, y2). A comparison of each model confirmed that the ResNet model has good location detection performance. Through this, it was confirmed that the proposed method alleviates the difficulty of first-time students learning electric and electronic experiments.

A photovoltaic/thermal(PVT) collector is a solar collector combining photovoltaic module with a solar thermal collector, which produces electricity and heat at the same time. The integration of PV modules with collector could cause the temperature rise of PV module that results in the reduction of PV system"s electricity generation. Therefore, in order to get more power and heat from PVT collector, it is necessary to extract the heat from PV module that in turn decreases its temperature. Hot air from PVT collector can be collected and supplied into ventilation system in building as pre-heated fresh air. For this study, an air type PVT collector was designed, and its electrical and thermal performance was analyzed through the experiments performed in outdoor conditions. The results indicated that the thermal efficiency of the PVT collector was 22% average and its PV efficiency was about 15% average.

트랜스미디어 시대에서 에디큐레이션의 의미에 대한 연구

박세현(Park, Se-Hyeon) 한국만화애니메이션학회 2016 만화애니메이션연구 Vol.- No.44

인터넷 및 디지털 미디어의 환경에서 미디어 수용자는 동일 콘텐츠를 다양한 플랫폼으로 이용하고 있다. 이처럼 여러 장르의 콘텐츠가 디지털 미디어의 기반에서 융합, 조합, 변형, 분화, 복제 등의 과정을 거치면서 새로운 콘텐츠의 형태로 전환되는 것을 트랜스미디어라고 한다. 트랜스미디어 시대에서 성공하는 콘텐츠를 만들기 위해서는 에디큐레이션의 작업이 필요하다. 에디큐레이션은 큐레이터의 큐레이션 작업에 편집과 의미를 부가하는 작업 행위이다. 그런 점에서 이 논문은 트랜스미디어 시대에서 출판 및 만화 콘텐츠의 에디큐레이션에 대한 정의와 의미를 분석했다. 에디큐레이션은 디지털 미디어 환경에서 콘텐츠의 생산자가 곧 소비자며, 소비자가 곧 생산자인 프로컨슈머/프로듀저를 유도하는 역할을 담당하는 프로세스다. 디지털 플랫폼과 디바이스의 다양화, 디지털 1인(혹은 SNS) 미디어의 등장 등은 출판 및 만화 콘텐츠에도 다양한 방식의 에디큐레이션을 요구한다. 미디어 생산자(혹은 수용자)의 의도에 따라 콘텐츠는 복제, 짜깁기, 분해, 해체, 하이퍼텍스트, 압축, 재구성 등의 과정을 거쳐서 새로운 콘텐츠로 탄생한다. 이처럼 에디큐레이션의 작업을 거친 출판 및 만화 콘텐츠는 미디어 생산자의 작업 방식은 물론, 미디어 수용자의 콘텐츠 독법에도 영향을 미친다는 점에서, 트랜스미디어 시대의 에디큐레이션은 중요한 의미를 지닌다. 출판 콘텐츠에서 에디큐레이션 작업은 챕터나 단락의 논리성 파괴, 구어체의 문장, 카드 뉴스의 활용, 동영상 및 미디어 콘텐츠의 변형 등이 있으며, 만화 콘텐츠에서는 칸의 파괴, 말풍선, 의성어, 의태어의 다양한 변형 등을 들 수 있다. Media consumers in the context of the Internet and digital media are using the same content to a variety of platforms. As such, the content of various genres is converted to the form of a new content through the process of fusion, combination, transformation, differentiation, reproduction, etc on the basis of digital media. That is referred to as trans-media. In order to create the successful content in trans-media era, it requires the work of Edi-curation. Edi-curation work is the act of editing and adding meaning to the curation work of curators. In that sense, this paper analyzed the definition and meaning for Edi-curation of publishing and comic(webtoon) content in trans-media era. Edi-curation process induces the changing role of consumers and producers of content in the digital media experience. In process of Edi-curation, consumers(producers) will soon lead to a media producer(consumer), namely proconsumer / produser. Diversification of digital platforms and devices, digital 1 person (or SNS) appeared in the media, etc. are also required to Edi-curation of content and comic(webtoon) published in a variety of ways. Depending on the intention of media producers (or consumers), content through the process of replication, montage, disassembly, dismantling, hypertext, compression, and reconstruction births to new content. The work of Edi-curation has the significance that it affects the way the media producers work in creative process, as well as the reading content of the media consumers. In the publishing content, Edi-curation work is the logicality destruction of a chapter or a paragraph, a sentence of colloquialisms, card news, the deformation of the utilization of video and media content. Meanwhile in the comic(webtoon) content, we mention the destruction of cut(frame), the various modifications of speech bubbles, onomatopoeia, and mimetic word.

Zero energy building is a self sufficient building that minimizes energy consumption through passive elements such as insulation, high performance window system and installing of high efficiency HVAC system and uses renewable energy sources. The Korea Government has been strengthening the building energy efficiency standard and code for zero energy building. The building energy performance is determined by the performance of building envelope. Therefore it is important to optimize facade design such as insulation, window properties and shading, that affect the heating and cooling loads. In particular, shading devices are necessary to reduce the cooling load in summer season. Meanwhile, BIPV shading system functions as a renewable energy technology applied in solar control facade system to reduce cooling load and produce electricity simultaneously. Therefore, when installing the BIPV shading system, the length of shadings and angle that affect the electricity production must be considered. This study focused on the facade design applied with BIPV shading system for maximizing energy saving of the selected standard building. The impact of changing insulation on roof and walls, window properties and length of BIPV shading device on energy performance of the building were investigated. In conclusion, energy consumption and electricity production were analyzed based on building energy simulations using energyplus 8.1 building simulation program and jEPlus+EA optimization tool.
