The Electronic Medical Record (EMR) is a valuable source of medical data intelligence in e-health systems. The watermarking techniques have been used to authenticate the owner and protect the EMR from illegal copying. The existing distributive strategies, successfully operated to secure the EMR, are found to be inadequate. Blockchain technology, mainly, is employed by a sharing database that allows the digital crypto-currency. It rapidly leads to the magnified expectations acme. In this excitement, the use of consortium adopting the technology based on Blockchain, in the EMR structure, is found improving. This type of consortium adds an immutable share with a translucent record of the entire business and it is accomplished with responsibility, along with faith and transparency. The combination of watermarking and Blockchain technology provides a singular chance to promote a secured, trustworthy electronic documents administration to share with the e-records system. The authors, in this article, present their views on consortium Blockchain technology which is incorporated in the EMR system. The ledger, used for the distribution of the block structure, has team healthcare models based on dissimilar multiple image watermarking techniques.

The article presents the analysis of modern methods of automatic comparison of original and unoriginal text to detect textual plagiarism. The study covers two types of plagiarism - literal, when plagiarists directly make exact copying of the text without changing anything, and intelligent, using more sophisticated techniques, which are harder to detect due to the text manipulation, like words and signs replacement. Standard techniques related to extrinsic detection are string-based, vector space and semantic-based. The first, most common and most successful target models for detecting literal plagiarism - N-gram and Vector Space are analyzed, and their advantages and disadvantages are evaluated. The most effective target models that allow detecting intelligent plagiarism, particularly identifying paraphrases by measuring the semantic similarity of short components of the text, are investigated. Models using neural network architecture and based on natural language sentence matching approaches such as Densely Interactive Inference Network (DIIN), Bilateral Multi-Perspective Matching (BiMPM) and Bidirectional Encoder Representations from Transformers (BERT) and its family of models are considered. The progress in improving plagiarism detection systems, techniques and related models is summarized. Relevant and urgent problems that remain unresolved in detecting intelligent plagiarism - effective recognition of unoriginal ideas and qualitatively paraphrased text - are outlined.

Complement is a special grammatical phenomenon in Chinese. There is no complement in Korean, so complement teaching is a difficulty. There are some similarities between the degree complement with "de" and the modality complement. For a long time, there has been a phenomenon of fuzzy classification in the academic circle, which also affects the teaching of Chinese as a foreign language. There are several different views on these two kinds of complements in the current textbooks. This makes students and teachers feel very confused. From the perspective of Chinese teaching, the author analyzes the characteristics, classification and grammatical significance of these two kinds of complements, and investigates the four sets of current teaching materials. It is found that: some teaching materials are confused in terms of terms and classification; some teaching materials are not fully reproduced in terms of knowledge points; the students are prone to have partial errors, and the situation of the clutch words with modal complements is ignored by most teaching materials. Some textbooks overemphasize Verb Copying in the arrangement of modal complements. Most textbooks are lack of context. The author puts forward some teaching suggestions. In class, teachers should concentrate on speaking and practicing, and focus on the types of errors that students are prone to make. The textbooks should be arranged according to the outline, the two kinds of "similar" complements should be clearly classified, the context should be added appropriately, and the textbooks compiled in South Korea can be nationalized. Students should listen carefully, participate in classroom activities and interact with teachers. Ask for advice in case of any problem you don't understand..

문서 요약은 길이가 긴 원본 문서에서 의미를 유지한 채 짧은 문서나 문장을 얻어내는 작업을 의미한다. 딥러닝을 이용한 자연어처리 기술들이 연구됨에 따라 end-to-end 방식의 자연어 생성 모델인 sequence-to-sequence 모델을 문서 요약 생성에 적용하는 방법들이 연구되었다. 본 논문에서는 여러 자연어처리 분야에서 높은 성능을 보이고 있는 BERT 모델을 이용한 자연어 생성 모델에 복사 메커니즘과 강화 학습을 추가한 문서 요약 모델을 제안한다. 복사 메커니즘은 입력 문장의 단어들을 출력 문장에 복사하는 기술로 학습데이터에서 학습되기 힘든 고유 명사 등의 단어들에 대한 성능을 높이는 방법이다. 강화 학습은 정답 단어의 확률을 높이기 위해 학습하는 지도 학습 방법과는 달리 연속적인 단어 생성으로 얻어진 전체 문장의 보상 점수를 높이는 방향으로 학습하여 생성되는 단어 자체보다는 최종 생성된 문장이 더 중요한 자연어 생성 문제에 효과적일 수 있다. 실험결과 기존의 BERT 생성 모델 보다 복사 메커니즘과 강화 학습을 적용한 모델의 Rouge score가 더 높음을 확인 하였다.

This paper attempts to read "The Nightingale" as an experimental proponent of Lyrical Ballads of 1798, one that inaugurated British Romanticism. It is never accidental for this poem to come to replace "Lewti" at the last moment of publication and to be tied to the poetic principles manifested in the "Advertisement" of the 1798 volume. The speaker of this poem, for example, is an ordinary man, who presents himself as a friend and a loving father. Opting for conversational styles rather than blindly copying literary conceits, he even incorporates an evening episode he happens to recall into a legitimate subject matter. The notion of "conversation," which appears in the subtitle, offers a key to figuring out the ideal of poetic language, the figure of the poet, and compositional procedures Coleridge and Wordsworth proposed in their collaborative project. "The Nightingale" can be a dubious, if not totally failed, poetical journey to subverting an incidence of misnaming acts. He finally reaches the limits of poetic figuration in a process of textualizing nature. The leitmotif of "In nature there is nothing melancholy" testifies to the fact that the bird nightingale, which the narrator is hard at work to rename as a joyous bird, is nothing but a poetic metaphor. "The Nightingale" is more likely to be a revisional, regenerative performance based on the strategy of conversation than an embodiment of a daring novelty.

The aim of this study is to understand problems with both fit and sizing system of gloves by analyzing the glove production industries with an emphasis on the sizing system, production measurement system, and general marking situation. Also, to suggest the basic raw materials for improving sizing system for gloves, actual glove control sizes were compared to the anthropometric data of the previous study Fifteen domestic production companies were participated in this study-Domestic glove production companies established their own sizing system by copying inter-national brand's glove sizing system or by their experience. The Korean Standard of gloves and the 1997 Korean Standard Anthropometrics Measurement for producing glove patterns are not considered because of its discordance with the reality of the required measurements. Domestic glove production companies used different size designation and labeling system. Size measurement unit also showed difference among the glove production companies. Some companies used 'cm', some used 'mm', some used 'inch' for the measurement unit. In general, companies produced 5 to 4 sizes in one design of glove and the production was the highest in M and L size. In 9 out of 15 companies preferred control size as hand length and hand circumference. For reference size, most of the companies preferred finger circumference, finger length, palm length, hand breadth, crotch height, and hand thickness. Actual glove sizes were compared to the anthropometric data of the previous study. The results indicated that most of the measurements of actual glove sizes were significantly larger than the anthropometric data.

MPEG(Motion Picture Expert Group)과 같은 멀티미디어 스트림은 연속적 재생으로 인해 데이터의 지속적인 디스크 검색을 요구한다. 따라서, 커널의 효율적인 지원이 필요한데, 유닉스 계열의 리눅스 버퍼 캐시 시스템은 비정기적이고 비실시간 데이터인 텍스트 데이터용으로 설계되었다. 대용량의 연속 미디어의 경우 커널 주소공간에서 사용자 주소공간으로의 대량의 복사가 이루어지므로 이 과정에서 CPU의 과중한 오버헤드가 발생한다. 이것은 시스템 처리율을 저하시킬 뿐만 아니라 QOS(Quality of Service)도 보장할 수 없다. 본 논문에서 이 메모리 복사 오버헤드를 감소시키기 위한 direct I/O와 one copy 기법을 리눅스 커널에서 설계 및 구현하였다. direct I/O는 디스크의 데이터를 커널 버퍼로 복사하지 않고 사용자 버퍼로 직접 복사하므로 CPU 오버헤드를 획기적으로 감소시킬 수 있다. 그리고, one-copy는 사용자 버퍼로 데이터를 복사하지 않고 직접 네트워크로 전송하는 기법이다. 구현 결과, CPU 오버헤드의 상당한 감소와 시스템의 처리율이 향상됨을 확인하였다.
