This study aims to establish a landscape plan that can preserve the identity of the region while meeting the unique functions related to land use of the Saemangeum agricultural land. In addition, it was intended to prepare a mid- to long-term landscape plan basic concept for the formation and management of the Saemangeum agricultural land landscape. Therefore, in this study, landscape management by type for processing/storage facilities, production/processing facilities, complex/sales facilities, and research/experimental facilities for facilities scheduled to move in after setting the direction and five strategies for landscape management considering the specificity of agricultural land direction was set. In addition, the landscape management direction for 6 common landscape elements such as buildings, open spaces, advertisements, colors, public facilities, and night scenery was also presented. In particular, Agroworks, Agro City, and Agro Town, which are important landscape areas, are landscape-focused management areas, and the landscape management direction for the area has been established. This study is considered to have great utility value when setting landscape standards for public or private buildings and infrastructure, development projects, etc. to be moved in prior to establishing a landscape plan for agricultural land. It is expected that it can be used as a basis for deliberation and review of the landscape standards derived from this study in the future landscape-related licensing for agricultural land.

IT산업의 새로운 패러다임으로 빅데이터 분석이 주요한 기술로 부각되고 있다. 본 논문에서는 빅데이터를 수집, 분석하여 이를 통해 피자 판매량을 예측하는 모델을 제안한다. 판매량 예측을 위하여 과거 판매 데이터와 함께 공휴일, 날씨, 뉴스기사, 경제지표, 트렌드, 스포츠 이벤트 등의 데이터를 수집하여 이용하였으며, 판매량 예측 방법으로는 회기분석과 인공신경망 학습 등을 사용하여 빅데이터를 사용하지 않은 경우와 정확도를 비교하였다. 실험 결과 빅데이터를 이용함으로써 예측 오차율이 5%이상 향상됨을 확인하였다.

Recently, the patent rights for 3D printing technology have expired, while 3D printers with RP (Rapid Prototyping or Additive Manufacturing) and 3D printing technologies are receiving attention. In particular, the development of 3D printers is rapid in Korea, thanks to the increasing sales and popularity of FDM (Fused Deposition Modeling or Fused Filament Fabrication) 3D printers. However, the quality and productivity of the FDM 3D Printer are not good, so customers prefer the DLP (Digital Light Processing) method to avoid these shortcomings. The DLP method has high quality and productivity. However, because of the stereolithography equipment, it has few studies compared to optimal values for elements then FDM 3D printing study. In this study, to find the optimal conditions for 3D printing with the DLP method, the aim is to obtain the optimal values (strength, final time, quality) by changing the light exposure time, layer thickness, and z-axis speed.

한국 문학이 세계로 뻗어나감에 따라 해외 시장에서 자리를 잡는 것이 중요해진 시점이다. 본 연구에서는 2016 년도부터 2020 년도까지 최근 5 년간 해외 출간된 도서들 중에서 굿셀러로 분류되는 누적 5 천부 이상 판매 여부를 예측하고자 했다. 굿셀러로 분류되는 도서는 전체 번역 도서 중 적은 비율을 차지하여 데이터 불균형이 발생하였으며, 본 연구에서는 SMOTE 기법과 앙상블 알고리즘을 적용하여 데이터 불균형 문제를 해결하였다. 그 결과, 데이터 클래스 비율이 1:1 에 가까울수록 성능 개선 효과가 나타났으며 LightGBM 모델이 99.83%의 AUC 값을 얻어 다른 앙상블 알고리즘에 비해 가장 좋은 예측 성능을 보임을 검증하였다. 또한 누적 5 천부 이상 판매 여부 예측에 있어 큰 영향을 미치는 변수로는 작가가 가장 중요한 요인으로 나타났으며 출간 국가, 그리고 평점 평균, 평점 참여자 수 같은 온라인 요인도 판매 예측에 유의미한 변수로 나타난 것을 확인할 수 있었다.

개인정보보호법에서는 정보 주체의 권리보장을 위해 개인정보보호 정책문서인 개인정보 처리방침을 공개하도록 규정하고 있고 공정거래위원회에서는 개인정보 처리방침을 약관으로 보고 약관규제법에 따라 불공정약관심사를 하고 있다. 그러나, 정보 주체는 개인정보 처리방침이 복잡하고 이해하기 어려워 읽지 않는 경향이 있다. 개인정보 처리방침의 내용을 간단하고 읽기 쉽게 한다면 온라인 거래에 참여할 확률이 증가하여 기업의 매출 증가에 기여하고, 사업자와 정보주체간의 정보 비대칭성 문제 해결에 기여할 것이다. 본 연구에서는 복잡한 개인정보 처리방침을 딥러닝을 이용하여 분석하여 정보주체로 하여금 가독성 높은 단순화된 개인정보처리 방침을 구현하기 위한 모델을 제시한다. 모델을 제시하기 위해 국내 258개 기업의 개인정보 처리방침을 데이터셋으로 구축하고 딥러닝 기술을 활용하여 분석하는 방안을 제안하였다.

This paper describes the real-time logic implementation of orthogonal matching pursuit(OMP) algorithm for compressive sensing digital receiver. OMP contains various complex-valued linear algebra operations, such as matrix multiplication and matrix inversion, in an iterative manner. Xilinx Vivado high-level synthesis(HLS) is introduced to design the digital logic more efficiently. The real-time signal processing is realized by applying dataflow architecture allowing functions and loops to execute concurrently. Compared with the prior works, the proposed design requires 2.5 times more DSP resources, but 10 times less signal reconstruction time of $1.024{\mu}s$ with a vector of length 48 with 2 non-zero elements.

In the textile industry located in Gyeonggi-do, 85% of small-sized firms have less than 10 employees; in addition, the most of them are characterized by a vendor relying specialization system that conducts foundry from the vendor that managed marketing, textile design development, and quality checks according to unit stream. The breakaway of these vendors accelerated over the last 7 years; however, industry survival is at stake because the specialization system and orders have collapsed. The following four main policies must be implemented to overcome industry hardship. Policies have been derived from survey and analysis (present condition and trends) from industrial statistics and related policies in advanced and developing countries. First, a policy to promote cooperation between small-sized foundry unit-streams. Second, unification of the marketing support function with a textile design and development support system. Third, the introduction of policy support-management system customized according to developmental stages (tall process${\rightarrow}$fabric production${\rightarrow}$sales${\rightarrow}$clothing production sales). Fourth, foundation of a control tower that puts these tasks in a vehicle and runs them and the division of roles with the central government. We must propel main tasks to manifest the developmental potential (develop eco-friend dyeing and processing technologies, change to the young next CEO in business environment, and grow the of knit market) of the Gyeonggi Textile Industry in a short period to present a condition where these four main policies are running.

This study analyzed management situations of two organizations that have produced environment-friendly agricultural and processed meat products. 'A' farming corporation sells environment-friendly agricultural products like as grains, vegetables, fruits and processing foods. 'B' agricultural corporation processes and sells environment-friendly processed meat products, specially organic and antibiotic-free beef products. Recently, members and production areas of 'A' farming corporation have decreased because of their aging and labor shortage. And Indices for the management analysis are stability ratio, activity ratio and profitability ratio. Stability ratio indices are debt ratio, net worth ratio, fixed ratio and current ratio. Activity ratio ones include fixed assets turnover and net worth turnover. And profitability ratio is showed through return on investment, net return on sales and return on equity.
