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.

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.

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).

‘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.

The possibility of semiological interpretations of Korean sea novels is boundlessly open. However, discussions developed thus far on this subject have been the opposite. This is because discussions of these novels put too much significance on whether or not the experiences embodied by the authors truly existed. As a result, the chance that maritime experience can itself be an object of recognition has been excluded, and the ocean as the basis of such novels has been read only as the visible ocean itself, without its hidden meanings being detected. The problem with such myopic interpretations is that it is inevitable that authorial experiences and reproductions in novels concerning the sea need to be open and candid. Moreover, the ocean groundings in these novels cannot be intact oceans. Instead, they are interpreted and recreated oceans. This study began from an awareness of this issue and analyzed maritime novels through the semiological interpretations of Lacan, Saussure, and Perice. This analysis makes it possible for us to not only pay attention to the overlooked lives around us, but also to find out what the literary contribution of maritime novels are, particularly in Korean literature. For this, I completely accept Deleuze's contention that a "symbol is not an object of contemplation, but an object which stimulates the mental system to initiate our thinking." Care was taken, however. Efforts were made to make sure that inducing semiology into studies on sea stories reconsidered and inproved upon the shortsightedness of old research rather than bolster-up an excessive theory for interpretation. The ultimate goal of this research is to scrutinize the relationships between the ocean, maritime experiences, and other things in life, and to discover the various meanings found in sea novels through the use of some semiology theories.

Target Strength(TS) is an important factor for the detection of the target in an active sonar system: thus the numerical model for the prediction of TS is widely being developed. For the frequency range of several ㎑, the most important scattering mechanism is known to be specular reflection, which is largely affected by the geometrical shape of the target. In this paper, a numerical algorithm to predict TS is developed based on the Kirchhoff approximation which is computationally efficient. The developed algorithm is applied to the canonical targets of simple shapes, for which the analytical solutions exist. The numerical results show good agreement with the analytical solutions. Also, the algorithm is applied to more complex scatterers, and is compared with the experimental data obtained in the water tank experiment for the purpose of verifying the developed numerical model. Discussions on the effect of spatial sampling and other aspects of numerical m odeling are presented.

재일교포사회의 형성과 민족 정체성 변화의 역사

Regarding Koreans residing in Japan as politically independent entity such as 'Nation' or 'Nationality', this paper investigates how they identified themselves and how their identities have changed in the course of their history. By overviewing how the political identity of Koreans in Japan as a subject or object of nationalism get strengthened or weakened throughout their history, I examine how their community has formed and how their national identity has changed depending on the political changes happened in Korean Peninsula in the past one hundred years. Prior to the annexation of Korea into Japan in 1910, Korean residents were scattered all over in Japan and their number was not enough to form their own community. Therefore, there was no community to be considered as a prototype of current Korean resident community in Japan. During the colonial era, although the political identity of Korean residents in Japan was legally Japanese citizens, their legal status was discriminated from Japanese people's and they received distorted treatment. The political identities of Korean residents themselves were not the same at that time: Some were loyal to the reign of Japanese empire, others lifted up their voices toward it, and a few protested against it. After Japan's defeat at the World War and the following liberation of Korea from Japan's colonization, Korean residents in Japan showed common identities as the people of the 'liberated country' through the repatriation to their own country and active participation in founding national organizations in Japan. During this period, they showed strong ties to Korea. However, their national identities have weakened since 'Choryun' was dissolved in 1949 and continues to weaken even today. Secession from nationalism has led to acquisitions of Japanese nationality and diminution of Korean permanent residents.
