Synthetic Aperture Radar (SAR) images are affected by noise called speckle, which is very severe and may hinder image exploitation. Despeckling is an important task that aims to remove such noise so as to improve the accuracy of all downstream image processing tasks. Many different schemes have been proposed for the restoration of SAR images. Among the different possible approaches, methods based on convolutional neural networks(CNNs) have recently shown to reach state-of-the-art performance for SAR image restoration. DnCNN(DeNoising Convolutional Neural Network) is one of the most widely used neural network architecture embedded in baseline SAR image despeckling methods. In military applications of SAR satellite image, fast processing is the most critical factor except the precision rate of the recognition. In this paper, we propose an improved DnCNN architecture for faster SAR image despeckling. The experimental results on real-world SAR images show that our proposed method takes faster processing time than the original DnCNN architecture without despeckling performance downgrade. Subjective visual inspection demonstrates that the proposed method has great potential in preserving the image signal details and suppressing speckle noise.

본 연구는 러시아-우크라이나 전쟁에 있어 유럽의 제재 조치를 분석하 고 이에 따른 시사점을 도출하는 데 목적을 둔다. Manner(2002)가 주장 한 EU의 규범적 권력(Normative Power)과 Portela(2005)가 적용시킨 EU 제재의 규범적 성향(Normative Characters)을 근거로 제재 조치의 동기를 살펴보았고, 개념틀을 통해 EU의 규범적 권력과 EU의 근린지역 에 미치는 영향력을 살펴보았다. EU의 제재는 결국 EU의 규범적 권력을 행사하는 것이 아닌 지역의 평화를 구축하기 위해 기울이는 규범적 성향 에 근거해 제재 조치를 시행한 것이다. 따라서 현재 EU의 규범적 권력 의 존재에 대해 예측 및 기대는 어렵지만 전쟁의 진행 여부에 따라 차후 검토가 가능할 것으로 생각된다.

현대사회 대부분의 교육은 전문화를 바탕으로 기능의 분화를 거듭하 였고, 이는 정보의 분산과 같은 새로운 문제를 만들어냈다. 실제로 초· 중·고 단위로 분화된, 유럽연합에 대한 교육과정은 정상적인 교과과정을 이수한 학생이라도 단일한 유럽을 이해하기 어려운 것이 현실이다. 바 로 이점에 주목해 “유럽연합의 전반적인 학습이 아닌, 지엽적인 국가별 역할에 집착하는 교육을 이수한 우리나라 대학생들은 유럽연합을 어떻 게 이해하고 있을까?”에 대한 질문을 던질 수 있다. 본 논문에서는 실 증분석을 통해 “유럽연합에 대한 교육 기관의 부재, Erasmus Mundus 프로그램, EU Centre 설립 홍보부족, 대학 입학에 의존한 주입식 교육 방법”이 미래의 인재인 대학생들이 유럽국가에 보이는 관심에 비해 유 럽연합을 제대로 이해하지 못하는 원인으로 파악하였다.

본 연구에서는 한중 FTA로 인하여 우리나라 대중 농산물 수입액이 어떠한 영향을 받았는 지를 품목별 미시자료와 다기간 이중차분모형을 적용하여 분석하였다. 2010년부터 2019년까지 FAO (Food & Agriculture Organization)의 품목별 대중 농산물 수입액과 연도별 양허 자료를 이용하여 2015년 이후 한중 FTA로 인한 품목별 양허가 우리나라 대중 농산물 수입액에 미친 영향을 분석하였다. 연도별 양허효과가 동일하다고 가정하면 양허로 인하여 양허대상 품목이 약 680~693만 불의 수입 증가 효과가 존재하고 있었다. 그리고 연도별 양허효과가 상이하다고 가정하면 2016년, 2017년 및 2019년은 양허대상 품목의 수입증가 효과가 통계적으로 유의한 것으로 나타났지만 2018년은 통계적 유의성이 낮았다.

Chinese land system has gone through several changes since modern times. Although some transformations are only tentative explorations, they have strong practical significance. During the period from 1851 to 1949, it included the National Land System, Sun Yat-sen’s idea of “equal land rights”, Jinggangshan Land Law and Xingguo Land Law during the Agrarian Revolution, as well as Outline of Chinese Land Law during the Liberation War. The changes of the land system has a distinct characteristics, productivity and production relations decide the change of land system in modern China, and the shackles of feudal ideas hindering such changes, moreover spontaneity and compulsory unification has carried out on the basis of the change of land system, while the cause of revolution in modern China emerging from such transformations.Review since modern times of China tell us the history of the land system change, we will improve the system of land laws and regulations, adhere to protect farmers’ interests, strengthen the position of public ownership is not moved, build a new era of agricultural management system can guarantee the healthy and orderly development of China’s land system, thus to promote the rural revitalization of the foundation and guarantee.

Streaming media is an emerging mode of video playback. It compress a series of multimedia data and transmit the data in real time through the Internet. And It has become an important part of people's daily entertainment and leisure. These streaming media platforms(Including OTT platforms) are full of enormous Intellectual Property(IP). Although there are some original IP, most of them are derived from Chinese classical culture and refreshed vigorously. Owing to digitalization, paper publications gradually broken the restrictions of physical forms and evolved to multiple digital forms in the world. In the thriving contemporary cultural industry, the needs for traditional classics are gradually surpassing that for the pure humanistic value, and thus the culture industry value of them are focused on. Xiyouji is the crystallization of the collective wisdom and imagination of the ancient folk, which has been active in people's daily life with various forms of popular cultural products, such as speech and opera, since the ancient time. Therefore, Xixingji is selected in to this paper as the study object, so as to discuss how the original work is effectively untilized in Xixingji to create the magnificent script and storylines and how Christopher Vogler's narratological theory is adopted to analyze the storytelling and character in animation Xixingji, and also to investigate the market reaction of Xixingji in China and South Korea.

This study analyzed the performance of the national fishing port development project, which lacked ex-post impact evaluation despite a lot of investment in terms of fishery income opportunities. Using micro data from the Census of Agriculture, Forestry, and Fisheries, the sales amount of fishery products and the proportion of fishery-related businesses were used as performance indicators. The fishery households in the fishing port area (treatment group) and those not in the area (control group) were classified through data pre-processing, and factors unrelated to the fishing ports were controlled using the propensity score matching difference-in-difference method. The analysis target is six fishing ports with large investment in from 2010 to 2014. As a result of the analysis, it was confirmed that the sales of fishery products increased significantly in four of the six fishing ports, and the proportion of fishery-related businesses increased in two fishing ports. The analysis method of this study can be fully utilized in the evaluation of the Fishing Community New Deal 300 Project, which is in need of performance analysis.

Variant Hán characters (hereinafter referred to as variants) are a common phenomenon in various types of Hán-Nôm cultural materials, including Confucian documents. This article studies the variants in Confucian works through the case of the book Hồ thượng thư gia lễ/胡尚書家禮/Family rituals by Minister Hồ (printed in 1739). The author chooses this text because of the following factors: First, the content of this work, which might be described as Confucian in nature, is about Confucian rituals; Second, the text printed in 1739 is associated with clearly identified dates of production and chief commissioner, so variants found in this text have historical value; Third, this is a printed text, so its variants must have attained a degree of common usage. On that basis, the objectives of this article are: First, to provide statistics on variants, to classify their structures and to analyze some variation rules of this type of characters; Second, to provide preliminary comments (relying upon the above-mentioned data and analysis) on the flexible use of Hán characters by Vietnamese Confucian scholars in the 18th century.

Among the research of Chinese Characters, there is a long history of the study of “the six categories of Chinese characters,” also a lot of research achievements have been accumulated from the past. Since the Qing Confucian Dai Zhen put forward the theory of “Four Noumenon and Two Uses,” advocated that the Transformed Cognates and Rebus are as the methods of using characters. The debates have been raised once again among different parties. Among them, the one with the most divergent opinions is the usage of “Transformed Cognates.” At the end of the Qing Dynasty and the beginning of the Republic of China, Mr. Zhang Taiyan made a theory from the perspective of the migrating of language. “The transformed Cognates, means that a new character created by changing the tone or the rhythm of the original character,” said Zhang. He clearly stated” a new character created,” regarded that “Transformed cognates” as a practice of creating new characters due to the transfers of sound. Which has always been seen as an important promoter of the theory. However, the subsequent researchers who also sat at the feet of Zhang have two different understandings and interpretations of “the method of using the character” and “the method of creating a character”. This article attempts to sort out the relevant discussion of Mr. Taiyan’s theory and restore the background of the time that Zhang made it. Also discussing the different interpretation perspectives of Zhang’s Transformed Cognates Theory by subsequent scholars in Taiwan. Finally, propose the author’s observations and conclusions.

Hepatic diseases are divided into two types: alcoholic and non-alcoholic. Non-alcoholic liver injury finally induces fatty liver and damages liver function. Many studies have demonstrated that Ecklonia stolonifera has antioxidative, antiinflammatory, and hepatoprotective activities. We conducted a 12-week double-blind, placebo-controlled, randomized trial to examine the efficacy of E. stolonifera extracts (ESE) on biochemical markers of hepatic function. Sixty-five subjects with mild or moderate liver injuries were randomly allocated to receive either 420 mg/d of ESE or a placebo for 12 weeks. Fifty-five participants completed the trial. No significant adverse events were observed among the subjects during the study. The primary end points were changes in plasma levels of aspartate transaminase (AST), alanine transaminase (ALT), and γ-glutamyltransferase (γ-GT). The secondary end points were changes in lipid profile levels, including total cholesterol (TC), triglyceride (TG), highdensity lipoprotein cholesterol (HDL), and low-density lipoprotein cholesterol (LDL). Compared with the baseline, AST and ALT levels decreased significantly in the ESE group compared to those in the placebo group (P<0.001). In addition, γ-GT levels in the ESE group were significantly lower than those in the placebo group (P=0.016). There were no differences in the TC, TG, HDL, and LDL levels between groups. In conclusion, ESE consumption for 12 weeks improved liver parameters in subjects with liver injury. Regular consumption of ESE could maintain liver health in individuals at risk of hepatic damage.

요통을 호소하는 환자에서의 자기공명영상 검사는 다른 영상 진단법에 비해 요추와 주변 조직에 대한 높은 대조도와 해상력, 다양한 영상면의 획득으로 해부학적 구조 파악과 다양한 척추 질환의 진단에 널리 활용되고 있다. 그러나 자기공명 영상 검사는 검사 시간이 길기 때문에 통증으로 협조가 되지 않는 환자들에게서 움직임에 의한 인공물을 유발하는 경우가 많아 검사 시간을 최소화하는 것이 중요하다. 이에 자기공명영상 검사 시간 단축을 위한 다양한 기법들이 개발되어 왔으며, 최근 높은 영상의 질을 유지하면서 검사 시간은 크게 줄이는 K-공간 기반 딥 러닝(K-space based Deep Learning, DL) 기법이 주목받고 있다. 본 연구는 요추 자기공명영상 검사에서 DL 기법의 유용성을 알아보기 위해 본원을 내원하여 척추 질환이 의심되는 환자를 대상으로 DL 기법 적용 전후 시상면 T2 강조 영상과 축상면 T2 강조 영상을 각각 획득하였으며, 신호대잡음비와 대조대잡음비, 영상 획득 시간, 전체적인 영상의 질 및 병변 진단 일치도를 비교 분석하였다. 연구 결과 영상의 질 향상과 검사 시간의 단축뿐만 아니라 빠른 영상 획득으로 움직임이나 호흡에 의한 인공물 또한 감소하는 것을 볼 수 있었다. 따라서 자기공명영상 검사에서 DL 기법 사용 시 진단적 가치가 보다 높은 영상을 제공하는 동시에 환자의 만족도를 높여 임상에서도 유용한 방법이 될 것으로 사료된다.
