실험 오차가 주파수 응답함수에 미치는 영향

정해일 ( Hae Il Jung ) 한국실천공학교육학회 2011 실천공학교육논문지 Vol.3 No.1

Despite the highly sophisticated development of finite element analysis, a finite element model for structural dynamic analysis can be inaccurate or even incorrect due to the difficulties of correct modelling, uncertainties on the finite element input data and geometrical oversimplification, while the modal data extracted from measurement are supposed to be correct, even though incomplete. The assumption that the test results represent the true dynamic behaviour of the structure, however, may not be correct because of various measurement errors. The measurement errors are investigated and their effects on estimated frequency response functions(FRFs) are also investigated.

중국 신소설론의 창작 실제와의 간극, 그 너머의 담론 고찰 - 저우쭤런(周作人) 「日本近三十年小說之發達」의 논점 검증을 중심으로 -

정해리,류창진 중국인문학회 2022 中國人文科學 Vol.- No.82

본 논문은 1918년 저우쭤런(周作人)이 「日本近三十年小說之發達」에서 중국 신소설 발전을 위해 제시한 주요 논점에 대해 검증을 진행하였다. 먼저, 周作人의 논점 검증을 위한 선행 검토로서 일본 메이지(明治) 17-18년의 문예 양상을 고찰한 뒤, 중국 신소설의 현주소와 20여 년의 담론 성과 간의 간극에 관하여 검증하였다. 검증 1)에서는 1890년대 후반 이후 20여 년의 중국소설 변혁을 위한 모색 성과들을 되짚어보면서 이 시기 중국 소설계가 과연 메이지 17-18년 양상에 정체되어 있는가에 대하여 논하였다. 검증 2)에서는 중국 신소설 발전을 위한 목전의 필독서, 일본의 『小說神髓』 학습에 착수해야 한다는 周作人의 주장과 관련, 중국 신소설 담론의 성과 가운데 소설을 예술의 한 장르로 자리매김한 쓰보우치 쇼요(坪内逍遥)의 인식과 맥락을 함께 하는 중국 논자들의 담론을 근거로 검증 작업을 진행하였다. 그리고 이와 같은 작업과 논의를 통해 그간의 중국 신소설 제 담론으로부터 周作人의 주장에 대한 반증을 도출해내었다.

G-PON에서 최대 링크 대역폭까지 할당이 가능한 DBA 알고리즘의 구현

정해,홍정호,Chung, Hae,Hong, Jung-Ho 한국정보통신학회 2009 한국정보통신학회논문지 Vol.13 No.8

TDMA PON 시스템에서 서로 다른 ONU들이 상향으로 데이터를 효율적으로 전송하기 위해서 동적 대역할당방식은 필수적이라 할 수 있다. 본 논문에서는 하향과 상향이 각각 2.5/1.25 Gbps 속도를 갖는 G-PON OLT를 위한 DBA처리기를 구현한다. 이 처리기는 매 사이클 타임마다 각 ONU로부터 전송되는 상향 프레임의 대역요청 메시지를 종합하고 트래픽의 우선순위와 공정성을 고려하여 Alloc-ID 단위로 대역할당을 수행한다. 제안된 알고리즘에서는 링크의 효율을 올리기 위하여 한 사이클 타임을 여러 개의 G-PON프레임 ($m{\times}125{\mu}s$)으로 구성한다. 특히, 어떤 ONU에게 할당하고자 하는 대역이 프레임과 프레임 사이의 경계에 걸쳐 있을 때에도 추가적인 오버헤더가 없도록 하는 방법을 사용하기 때문에 링크의 효율이 높다. 이로 인하여 어떤 ONU에게 0에서 상향 대역의 전체에 이르기까지 대역을 융통성 있게 할당할 수 있게 된다. 제안된 DBA 처리기는 FPGA로 구현하며, 계측기를 통하여 ONU들에 대한 대역할당 과정을 보여준다. In the TDMA PON system, the DBA is essential for ONUs to send data efficiently to the upstream. In this paper, we implement a DBA processor for the G-PON OLT with downstream and upstream rate, 2.5 and 1.25 Gbps, respectively, The processor collects bandwidth request messages from ONUs at every cycle time and allocates properly bandwidth to each Alloc-ID with considering priority and fairness for traffics. In the proposed DBA algorithm, one cycle time consists of multiple G-PON frames ($m{\times}125{\mu}s$) for high link efficiency. In particular, the link efficiency is higher because the algorithm adopts a method that an additional overhead is eliminated when an allocated bandwidth is laid between two G-PON frames for an ONU. This enables that the processor flexibly allocates the bandwidth from zero to the maximum link capacity for an ONU. The proposed DBA processor is implemented with the FPGA and shows bandwidth allocating processes for ONUs with logic analyzer.

근대 중국 미술 개념과 문학의 조우 및 소통 시탐(試探) - 미술의 공리적 가치 부여에서 문예의 독립적 지위 획득까지-

정해리,류창진 중국인문학회 2020 中國人文科學 Vol.0 No.74

This study aims to shed light on the concept and value perception of modern Chinese art, and to re-examine it from the overall perspective of literary theory. Specifically, this study is based on trends and perceptions of modern art concepts in East Asia, encounters in contemporary Chinese art and literature, and communication between modern Chinese art concepts and essentialism of literature: The process was divided into three parts, from the utilitarian value of art to the acquisition of independent status in literature. First, the trends and perceptions of East Asian modern art concepts were examined. In the case of Japan, it can be seen that utilitarian values are perceived to promote national policy in the trend of modernization. In terms of China, Kang Youwei(康有爲) insisted that "the social function of art and artists should be emphasized, and national education and nationality reconstruction should be carried out together." Cai Yuanpei(蔡元培) emphasized the universality and transcendence of beauty. Since the 1900's, it has been discussed in Liang Qichao(梁啓超), Wang Guowei(王國維) and Lu Xun(魯迅). The fact that the concept of beauty or art mentioned in Chinese modern literary literature is connected with Western and Japanese modern times serves as a clue to the formation of Chinese modern literary discourse. Therefore, as a first step of the study, this study examined the concept of Japanese art, the accepting aspect of China, and the trend of modern Chinese art. Second, the encounter between modern Chinese art and literature was examined. If the use of the term art mentioned in literary literature is largely focused on utilitarian aspects, Wang Guowei disagrees with the discussions of the time. He considered "fiction belongs to the category of art," and he considered "the best of Chinese poems, plays, and novels." Huang Ren(黃人) also said that "fiction is one of the aesthetically oriented literatures," which is the beginning of the encounter between beauty and literature. Zhou Zuoren(周作人) also recognized that the novel was clearly a sentence and a work of art. Guan Daru(管達如) and Lu Simian(呂思勉) then systematically organized the theory of the novel in general. In particular, Guan Daru attempts to position each of literature, art and fiction on the premise that "literature is a kind of art, fiction is also a kind of literature."In short, as art begins to be discussed with literature, journalists link "beauty and literature" and "beauty and novels." And with the understanding of literature in general, the position between art, literature and fiction becomes clearer. Third, this study examined the process from granting utilitarian value of art to acquiring independent status of literature, focusing on communication between modern Chinese art concept and literary essentialism. Xia Ren(俠人) talks about the ratio of fiction between fiction and history, emphasizing the creation of fictional realms and focusing on the essential characteristics of fiction. In other words, the literary value of the novel is highlighted. In addition, he pays attention to the utility values and literary characteristics of novels and moves his eyes to the aesthetic values of novels. Huang Ren paid attention to the useful value of the novel based on an aesthetic angle. Wang Guowei, on the other hand, strongly argues that if philosophy and art are the means of morality and politics, then the work is ultimately worthless. This claim completely overcomes the view of traditional Chinese literature and emphasizes the true independence of literature. Lu Simian systematized theories of novel creation based on the recognition that novels are artistic creations. In particular, the point of meaningfully discussing the fictional novels by dividing the novels is that they also pay attention to the value of literature itself.

近代 韓․中 文化交流 小考

정해리,류창진 중국인문학회 2012 中國人文科學 Vol.0 No.50

本論文作爲構築‘文化深層構造’工作的環節,將注目處於同一的近代轉換期的韓ㆍ中兩國間的異同裏金澤榮和張謇兩位文人的交流. 金澤榮(1850∼1927), 1905年亡命於中國, 在張謇的幫助下, 擔任過南通的翰墨林蔭書局裏做過編輯,出版等. 至1927年去世前, 在中國的22年裏, 對韓ㆍ中兩國的文化交流譜寫了新篇章. 張謇(1853∼1926)在壬午軍亂, 初次到朝鮮時就和以金允植, 金澤榮爲主的朝鮮文人有所往來, 爲近代韓ㆍ中兩國的文化交流留下了不少的足跡. 因此盡可能的通過金澤榮, 張謇兩位文人的交流作爲根本的尺度作用, 來觀察兩國的政治ㆍ時代性,以及個人的情況. 因此, 朝鮮和中國在近代史形成上有著同質意識,就是金澤榮和張謇的交往, 可以看做是對近代命運達成共同的時代認識和理念溝通的起到了一定的作用. 他們的交流本身就有著很多意義, 而且在側面,既構築了東亞文化交流人際網絡也爲東亞文化論堅實的未來起到了一定的作用.

근대 중화질서의 재편과 조선 인식의 변용: 마건충(馬建忠)의 『東行三錄』을 중심으로

정해리,류창진 중국인문학회 2020 中國人文科學 Vol.0 No.76

In the 19th century, Korea, China, and Japan faced different value systems, such as pressure and civilization from Western powers. In other words, we experienced a paradigm shift from the Chinese order represented by the “concept of courtesy” to the modern international order based on the “concept of national equality”. On the premise of this point, MaJianZhong's 『東行三錄』 is a vivid record that stood at the very center of the establishment of a new order in East Asia based on the periodic and political background of modern China and Joseon. Therefore, this study attempted to clarify the reorganization of the modern Chinese order, the response of China, the transformation of the perception of Joseon, and the modern transformation of the relationship between Korea and China through a political intent on 『東行三錄』. One of the pillars of 『東行三錄』 is the reorganization of the modern Chinese order and China's response. In the 19th century, China faced the Western powers in earnest through a new way of bargaining between countries, defined as a “treaty system”. And this appears in the form of a challenge to the traditional sovereignty of Chinese countries, in other words, in the form of denial and reorganization of the traditional international order in East Asia. In the process of mediating and signing a treaty between Joseon and Western powers such as the US, Britain, France, and Germany, MaJianZhong focused on obtaining the approval of the Qing's sustenance over Joseon. The traditional relationship between Qing and Joseon was order of courtesy represented by tributary appointment relationship, but the Qing did not directly engage in Joseon's internal affairs and diplomacy. The relationship between the two countries was different from the relationship between the suzerain country and the subordinate country in the exercise of the sovereignty stipulated in international law. In order to overcome this reality, China attempted to change from order of courtesy to a relationship between actual domination and subjugation, and further stipulate the rules of subordination within the treaty between Joseon and Western powers. Through this process, China was able to pursue a transition to a practical immediate release policy. Another pillar of 『東行三錄』 is the transformation of Joseon consciousness and the modern transition process of Korea-China relations. Establishment of treaty relations between Joseon and Western powers meant that the traditional relationship, gyorin was practically ended. MaJianZhong's perception of Joseon is based on this periodic and political process. Therefore, this study analyzes the process recorded in 『東行三錄』 into the recognition of traditional Joseon-China relations, the modernization of Joseon, and the recognition of the Im-O Military Revolt and Lee Haeung. Moreover, the conversion of Korea-China relations was identified. In connection with the modern transformation of the relations between Korea and China, China imposed a new form of “tributary state” system on Joseon. In particular, the political and military external pressure exerted by China after the Im-O Military Revolt was a decisive factor that hindered Joseon's transition to modern society. In addition, this "tributary state" system interfered with both internal and external affairs of Joseon. Moreover, the Qing's rule of thumb followed the Western imperialist state's domination, which is the colonial rule. Considering these points, MaJianZhong's 『東行三錄』 shows the coexistence and confrontation between the tributary appointment relationship and the modern international order amid a common perception of the modern destiny of both Korea and China.
