본 논문은 적응적 망 경로 선택 기능을 최대한 활용하기 위하여 두 가지 새로운 큐 구조 DAMQWR와 VCDAMQ를 제안하였다. DAMQWR은 리쿠르트 레지스터를 사용하여 정체된 채널의 메시지를 비 정체 채널로 라우팅을 유도할 수 있게 하여주며 VCDAMQ는 가상 채널상의 교통량을 동적으로 지원하도록 함으로써 망의 흐름을 보다 원활하게 하여 준다. 시뮬레이션과 분석을 통하여 제안된 큐 구조의 특성과 성능을 평가하였고 그 결과 제안되어진 큐 구조들인 VCDAMQ와 DAMQWR 구조가 메모리 및 망의 자원을 효과적으로 사용하여 적응적 라우터에 가장 적합함을 알 수 있었으며, 실험결과에서 기존의 DAMQ에 비하여 최대 $20\%$까지 망의 통신 성능이 향상됨을 보였다. This paper proposes DAMQWR and VCDAMQ architectures that enloit the full capabilities of adaptive routing. DAMQWR enables messages in congested channels to route through non-congested channels by using recruit registers while VCDAMQ dynamically assigns resources among virtual channels, resulting in better network traffic control. Through extensive simulations and analysis, this paper evaluates their effects on overall network cost and performance. These proposed queue architectures, VCDAMQ and DAMQWR are shown to appropriately support adaptive routing capability by dynamically and efficiently managing queue and network resources, increasing network performance. The results show that up to $20\%$ higher throughput can be obtained in comparison to traditional DAMQ designs.

Purpose: In this study, the outcome of internal limiting membrane (ILM) peeling in idiopathic macular hole surgery with or without indocyanine green (ICG) was investigated. Methods: Thirty eyes of 28 patients with idiopathic macular hole stage 3 or 4 who underwent vitrectomy were included. Follow-up duration in all cases was longer than 6 months. We analyzed the anatomical and functional results of macular hole surgeries using ILM peeling with (15 eyes) and without ICG (15 eyes). Results: There were no significant differences in sex, age, symptom duration, hole size, preoperative corrected visual acuity, or follow-up duration between the two groups. Anatomical success rates were 93.3% (14/15 eyes) in ILM peeling with ICG and 80.0% (12/15 eyes) in ILM peeling without ICG. In the cases of anatomical success, there was a statistically- significant difference between the functional success rates of 50.0% (7/14 eyes) in ILM peeling with ICG and 91.7% (11/12 eyes) in ILM peeling without ICG. Conclusions: While there was no statistically-significant difference in the anatomic success rate for idiopathic macular hole surgery with and without ICG, our results suggest the ILM peeling using ICG might produce a negative effect on functional success. Further studies are necessary to evaluation the toxicity of ICG in the context of macular hole surgery.

소아 굴절검사방법에 따른 차이 비교 및 생활양식이 근시에 미치는 영향

최영호,최윤영,Young-Ho Choi,Yun-Young Choi 대한안과학회 2005 대한안과학회지 Vol.46 No.11

Purpose: We examined the several refractive errors and measured the axial length of child patients who visited Fatima Hospital and then assessed the distribution of refractive error and axial length. We also compared the patients` life-styles with refractive error and axial length. Methods: We examined automated refraction, manifest refraction, 1% Cyclogyl refraction, 1% atropine refraction and axial length with an A-scan in patients between 5 and 15 years old. We asked their parents to provide information about the life-style of the patients using a questionnaire. Results: The difference between manifest refraction and 1% Cyclogyl refraction was significant in patients under 9 years of age, but not significant in patients over 10 years of age. We found that the greater degree of myopia the patient had, the longer the total length and vitreous length. Patients who played outdoors for less than 2 hours per day, read more than 2 books per week and had 1 or more parent with myopia, had greater degrees of myopia. Conclusions: We found that 1% Cyclogyl refraction with manifest refraction is necessary for refraction examination in children, and the degree of myopia is closely related with an indoor life-style, the amount of reading books and the parents myopia.

This study purposes at applying knee joint taping to preventing muscle fatigue. Twenty six subjects between the ages of 20s and 30s were randomly sampled among healthy males, with an average age of 26yr(range, 22 to 31yr). None of the subjects had a recent or remote history of significant lower extremity injury, No subjects had a history of central nervous system equilibrium problems. To develop muscle fatigue, Isokinetic exercise, which is a repetition of flexion and extension knee joint to $180^{\circ}$/sec, was performed 50 times per person. During the exercise, change of proprioception were measured by applying taping on both knee joints. Analysis has carried out by means of one-way ANOVA with repeated measures and independent t-test at the significance level of $\alpha$=0.05 to detect statistic significance. The results of this study were as follows: First, it was found that the generation of lower extremity muscle fatigue significant affects on proprioception (p < 0.05). Second, the application of taping to knee joint after the generation of lower extremity muscle fatigue significant affect proprioception (p < 0.05). Third, while continual exercise after the generation of muscle fatigue, taping group was significant differences in proprioceptive loss than non-taping group(p < 0.05).

군산거주 일본인의 귀환과정에 나타난 지역적 특성

This paper analysed the characteristics in population of Japanese people lived in Gunsan and Okgu area, and drawed the localities in formation and activities of Gunsan Sewakai as autonomous organization in relation to repatriation of colonials through the investigation on the resources written by residents there. The most important task of this paper is to find out local features of Gunsan comparing to Seoul and Busan which I had already researched. I tried to find out the localities in the memoirs of repatriates concerned as far as possible. And I tried to realize partly my critical point that we need to have multilateral sight towards repatriations of Japanese people in Korea under the definition of localities. We can confirm that Japanese community in Gunsan, in spite of distorted colonial society, had higher fixedness than other areas. Thus the fixedness made Gunsan’s colonials want to remain there even after the liberation of Korea. Duration around 6 months of Gunsan’s Sewakai was shorter than Seoul or Busan, but it sustained comparatively stable executive members. And it started its first mission procuring the ships for voluntary repatriates from Gunsan Port as notable activity. It also had to fulfill the instructions for unconditional banishment under the occupation of U.S. armed forces, but the activities can’t be seen so much in the related documents. この論文は、解放直前の時期に、群山と沃溝地域に居住していた日本人の人口構成における特徴を分析し、解放直後の群山日本人世話会の結成過程や組織活動を史料に基づいて確認することによって、日本人引揚の地域的特徴を見い出すものである。すでに研究されたソウルと釜山の世話会組織と比べながら、群山の地域性を見つけるものである。なるべく世話会の関係者によって書かれた回顧録を中心に、群山地域における日本人の引揚過程と、これをめぐる世話会の活動を整理した。在朝日本人の引揚に向けて、複眼的な見方をもって見るべきであるという問題意識は、史料や先行研究の検証を通じた地域性の究明により、部分的ではあるものの実現しようとした。 解放直前の群山地域における日本人の状況では、歪曲された形ではあったものの、他の地域とくにソウルや釜山と比較すれば、日本人の現地定着性が非常に高かったことが最も刮目すべきことである。したがって解放直後の引揚過程においても、一般民間人の‘残留’の動きが他の地域に比べて相対的に強かったという、地域的特徴が伺われるのである。群山世話会の組織をソウルや釜山と比較して言えば、6ヶ月程度の短い存続期間で終わったが、その間釜山よりは相対的に安定した役員構成を維持していた。また群山世話会の組織活動の面では、結成初期において地域居住の日本人の権益擁護のために働く中で、個別的な引揚のために船舶を手配したことが特記すべきである。それから米軍の進駐の後では、計画引揚のための援護活動を余儀なくされたが、この活動の記録はあまり残されていない。

‘擧銃’과 ‘執筆’ 사이:蔣光慈의 『菊芬』을 다시 읽는 몇 가지 讀法

최영호(Choi, Young-Ho)(崔瑛祜) 대한중국학회 2021 중국학 Vol.74 No.-

프로문학이 갖는 정치성은 어떤 스펙트럼을 보여줄 수 있을까? 蔣光慈는 기존의 평가(혁명+연애의 클리셰)와는 달리 색다른 소재와 콘셉트를 시도하여 프로문학의 地境을 넓혀간 작가임을 기억할 필요가 있다. 존재의 외연을 확장하는 일. 감정의 파동이 일어나는, 가장 내밀한 실존으로의 침잠. 이 모순된 방향의 움직임이 蔣光慈의 서사에서는 동시에 포착된다. 蔣光慈는 혁명의 파고를 관통하면서 첨예한 아이덴티티의 ‘경계’를 경험했던 문제적 인물들을 그려낸다. 주류 서사와 비주류 서사가 공존하는 蔣光慈의 세계는 좌익문학사에서 독특한 위치를 점한다. 무엇보다 혁명의 관습과 윤리가 힘을 잃는 내면의 깊은 곳, 그곳에서 마주하게 되는 공허함은 혁명 서사의 圖式을 뛰어넘는 어떤 울림을 선사한다. 본고는 그 울림과 함께 ‘이데올로기’를 초월하는 ‘개체’의 존립 가능성을 蔣光慈의 『菊芬』 속에서 탐색해 보고자 한다. Is there any other possibility for the relationship between literature and politics other than remaining as an incurable symptom? It was this question that led me to a novel by Jiang Guang Ci (蔣光慈). Two movements toward contradictory directions, one toward the extension of existence range and the other toward to concentration in the existence in the deepest inside felt as a wave of emotion are captured simultaneously in the narrative by Jiang Guang Ci. He asks what the usefulness of literature is in the high waves of the revolution, and how poor the exclusive feeling enjoyed by the order of revolution is. These are the reason the world of his literature where mainstream and non-mainstream narratives coexist is unique. Above all, the emptiness encountered in the deep inside where the ethics and custom of the revolution lose their power leaves us an impression that goes beyond the typical scheme of the revolutionary narrative. This study, in a novel by Jiang Guang Ci, explores the possibility of existence of the ‘object’ that overcomes the ‘ideology’. While the politics in real life is in the realm of ‘institution’, that in literature is in the realm of ‘sensation and awareness’. Considering that there is difference in the pattern of intervening politics between literature and real world, is it possible for the literature, through the convergence and divergence determining the condition of our life, such as conflicts between words occurring due to the fixation of the existing system, between institutional norms and ethics, between the oppressive structure and the desire to escape from the structure, and conflicts over the preoccupation of current and future values, to transform the real world in the situation where the poetic sentiments are inhibited by politics of the real world? The Jiang Guang Ci‘s novel rekindles the fundamental skepticism that literature itself may be politically helpless. If it is accepted positively, however, that Ju fen‘s participation in the revolution had some relation to the affection(情感) germinated from the ’poetic sensibility‘ the politics of literature may be regarded a goal that should not be abandoned. Although the process of visualizing of literary sensibility and affection as a political capability remains uncompleted, ’Ju Fen ‘(菊芬) written by Jiang Guang Ci is worth reading again in that this novel fills the uncompleted space in a novel way.

‘속도’에서 ‘깊이’로 - 蔣光慈의 『野祭』를 새롭게 읽는 몇 가지 讀法 (1)

최영호(Choi, Young-Ho)(崔瑛祜) 대한중국학회 2020 중국학 Vol.70 No.-

1928년 벽두 좌익문단을 뜨겁게 달군 이른바 ‘속도’와 ‘정서’의 이슈는 혁명문학에 대한 근본적인 질문을 던지며 폭발적인 반응을 일으켰다. 논쟁의 도화선이 된 蔣光慈의 『현대중국문학과 사회생활』은 혁명을 ‘속도전’이 아닌 모종의 감정 상태로 규정한 점에서 문제적이다. 여기서 蔣光慈는 理性만으로 환원되지 않는 혁명의 또 다른 양상을 포착하고, 혁명은 일거에 판을 바꾸는 데서 끝나지 않으며, 일상에서 그 情緖를 꾸준히 길러 舊習을 무력화하는 데까지 나가야 한다는 점을 역설한다. 숙성의 시간이 담보될 수 없는 속전속결의 시대에 蔣光慈의 진단은 매우 흥미롭다. 그것은 물론 기성의 프로문학과는 차별화된 ‘또 하나의 프로문학’으로 자리매김할 것이다. 본고는 蔣光慈의 시도가 어떻게 기성 문단과는 차별화된 혁명을 연출했는지 評論과 作品을 함께 읽어가면서 새로운 논의의 불씨를 지펴보고자 한다. The issues associated with “speed” and “emotion” that heated up the left-wing literary world at the very beginning of 1928. They caused an explosive reaction while asking fundamental questions about revolutionary literature. “Contemporary Chinese Literature and Social Life”, written by Jian Guang Ci, triggered this dispute. The article defined revolution as an emotional state rather than a “speed battle”. It is meaningful to review it since it put the brakes on the revolution as an ideology and the movements followed the “Grant recit”. Here, we can capture another aspect of the revolution that cannot be returned by only using rationality. The revolution does not end by changing everything upside down at one stroke, but it should continue until it incapacitates the old habits by cultivating the sentiment continuously. Is that the reason? Jiang Guang Ci’s gaze reaches to the abyss through the e-motion towards the e-out. In the “dimension of affection”, the revolution is implied by the changes in “trust” and “sympathy” deep down inside where numerous clues of emotion are condensed. “Additionally, pluralistic values and worldviews exist in the space where these emotions operate and conflicts between them are inevitable. Therefore, these conflicts are always associated with emotional elements such as commitment, attachment, involvement, and loyalty to a value or a worldview. It does not try to divide politics into ‘public ration’ and ‘private emotion’ dichotomically. Moreover, it supports the idea that we cannot understand it in this way.” “The knowledge of revolution emotion”, a process to find clues of feelings regarding the revolution in a myriad of emotions and cultivate them appropriately, is thus attrition warfare rather than temporary entertainment or collective excitement. While living in the era of a blitzkrieg where the time requiring for maturity cannot be guaranteed, the diagnosis of Jiang Guang Ci is extremely interesting. It will, of course, be established as another “professional literature”, different from the established professional literature. This article aims to discuss how Jiang Guang Ci’s attempt led to a revolutionary situation, separated from the conventional literary world, using individual works.
