국내 데이터 산업 시장의 규모는 점차 증가하고 있지만, 데이터 거래 분야의 성장은 매우 소극적이다. 현존하는 데이터 거래 플랫폼들은 관리자가 수동으로 API 를 검수하는데, 이러한 자동화된 시스템의 부재는 국내 데이터 거래를 적극적으로 활성화시키기 어렵다. 이에 본 논문에서는 JSON Schema 기반의 API 명세를 바탕으로 API 의 유효성을 자동으로 검증하는 방식의 데이터 거래 플랫폼을 제안하고 설계 및 구현하여 데이터 거래 시장의 진입장벽을 낮추고자 한다.

심층강화학습에 완전 연결 신경망과 합성곱 신경망은 잘 활용되는 것에 반해 순환 신경망은 잘 활용되지 않는다. 이는 강화학습이 마르코프 속성을 전제로 하기 때문이다. 지금까지의 강화학습은 환경이 마르코프 속성을 만족하도록 사전 작업이 필요했다, 본 논문에서는 마르코프 속성을 따르지 않는 환경에서 이러한 사전 작업 없이도 순환 신경망의 은닉 상태를 통해 마르코프 속성을 학습함으로써 학습 성능을 개선할 수 있다는 것을 소개한다.

인공지능은 스스로 학습하며 기존 통계 분석보다 탁월한 분석 역량을 지니고 있어 스마트팩토리 혁신에 새로운 전기를 마련할 것으로 기대된다. 이를 증명하듯 스마트팩토리의 주요 분야인 공정 간 연계 제어, 전문가 공정 제어, 로봇 자동화 등에서 활발한 연구가 이어지고 있다. 본 논문에서는 소포물 분류 시스템에 전통적인 룰 기반의 제어 방식 대신 다중 에이전트 강화 학습 제어 방식을 설계 및 적용하여 효과적인 행동 제어가 가능함을 입증한다.

Although pipe performs various functions in industrial sites and residential spaces, if it is damaged due to corrosion caused by the external environment, it may cause equipment failure or a major accident. For this reason, various studies for safety management are being conducted, but studies on detecting corrosion or cracks on the pipe surface using a laser displacement sensor have hardly been conducted. Therefore, in this study, the corrosion degree of the pipe surface was compared and classified into 4 corrosion conditions, and inspection equipment using a laser scanner was manufactured. The corrosion height was calculated from the four surface data obtained from the measuring equipment and applied to various CNN algorithms, and 91% accuracy was obtained during training using the Modified VGGNet16 code with reduced number of parameters.

Nitrate is an important nutrient and signaling molecule in plants that modulates the expression of many genes and regulates plant growth. In this study, we cover the research status of transcription factors related to the control of gene expression by nitrate signaling in higher plants. Nitrate reductase is a key enzyme in nitrogen assimilation, as it catalyzes the nitrate-to-nitrite reduction process in plants. A variety of factors, including nitrate, light, metabolites, phytohormones, low temperature, and drought, modulate the expression levels of nitrate reductase genes and nitrate reductase activity, which is consistent with the physiological role if. Recently, several transcription factors controlling the expression of nitrate reductase genes have been identified in higher plants. NODULE-INCEPTION-Like Proteins (NLPs) are transcription factors responsible for the nitrate-inducible expression of nitrate reductase genes. Since NLPs also control the nitrate-inducible expression of genes encoding the nitrate transporter, nitrite transporter, and nitrite reductase, the expression levels of nitrate reduction pathway-associated genes are coordinately modulated by NLPs in response to nitrate. Understanding the function of nitrate in plants will be useful to create crops with low nitrogen use.

전기공학은 급진적 발전으로 말미암아 그 깊이가 더욱 심오해지고 범위가 확대되어 한 개의 전공분야로 머물러있기가 어렵게 되었다. 그래서 이를 여러개의 전공분야로 나누고 있는데 이의 구분은 각자의 소견에 따라 상이할 뿐 아니라 그 내용에도 차이가 많은 것으로 알고 있다. 필자는 이런 문제의 취급에 있어 참고가 되기를 희망하면서, 전기공학의 종가격인 에너지 변환공학을 주축으로 하는 전력 공학분야를 전기공학 교육이라는 주제로 다루어 보았다.

The new plan for the current computer engineering involved in education and research in the values of the major and one of the female students, and you can improve your major satisfaction and retention training and development assessment process is the point of need. in computer engineering majors can be linked to the process of targeted quantitative and qualitative research conducted by the results of major and career choices of students turned out to be a mismatch could result in the phenomenon of female engineering escape. How to study ICT in education for female students to computer engineering major regional, historical and social context should be re-designed to suit the characteristics and analysis of exposed female students majoring computer engineering from anxiety and weak organization that has a sense of belonging, and to offer the first and is the appropriate teaching methods seems to be.

In this study, experiments with a floater using flapping foils were performed to develop a new station keeping system that can maintain its position in waves without mooring lines. The foils applied to this system generate thrust using wave energy. In this experiment, the motion of the floater was analyzed in three different wave periods. Sixteen foils were attached to the cylindrical floater. The thrust of each foil was controlled by changing its azimuth angle, and three cases were compared. Based on the previous data, we made more precise measurements and found an optimal model for stationkeeping under each wave condition. We verified the potential of this new stationkeeping system using flapping foils, and conclusions were drawn from the results.
