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).

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.

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.

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.

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.

한국 해양소설의 현 단계와 전망, 그 복된 짐

해양소설의 문학적 의미는 일반문학이 추구하는 것과 크게 다르지 않다. 다만, 다른 것이 있다면 보편적인 인간성 옹호와 문학정신의 표출 양상의 상이함이다. 그간 쥘 베른의 소설들은 대표적인 해양소설로 읽혀졌고, 우리 또한 그렇게 믿었다. 그런데 쥘 베른의 소설들에 나타난 바다는 실제적인 바다가 아닌 해석된 바다였다. 이를 안다면 좀 더 새로운 이해가 필요하다. 그의 소설은 ‘실재계는 바로 상상계다(L’imaginarie c’est le reel)’라는 의미심장한 전제 아래 씌어졌고, 여행, 과학의 발명, 식민지 건설이 작품의 중심 주제였다. 문제는 이런 전제와 주제가 당시 제국주의의 논리를 합리화시킨 데 있다. 이런 비판은 그간 행해진 쥘 베른의 해양소설에 대한 재평가와 해양소설에 대한 새로운 이해의 단초를 제공한다. 우리의 해양소설은 바다를 너무 고정 관념에서 주시했다. 그로 인해 해양소설이 보여주는 다양한 양상을 놓쳤다. 해양소설만의 주된 특성들은 간과되었고, 작품에 투영된 중층적ㆍ복합적 관계들도 간단히 처리되었다. 인간과 바다가 만나는 접점에서 발생되는 수많은 삶들은 땅을 보던 눈으로는 놓칠 수 있다. 더욱이 그런 삶들은 그 자체로 머물지 않고, 우리의 내면적 삶까지 새롭게 변형시킬 수 있다. 본 연구는 작가의 거주지나 바다체험에 대한 맹목적인 강조를 넘어 우리의 해양소설이 어떻게 걸어왔는지를 살폈다. 많은 작품은 아니지만, 특별히 주목되는 작품들을 중심으로 해양소설의 고유한 문학적 특성을 일별했다. 그러면서 우리 해양소설이 걸어갈 앞으로의 길도 모색했다. 이를 계기로 해양소설을 탄생시킨 우리의 문화적 전통과 역사로부터 부여된 삶을 반성적ㆍ체계적ㆍ완성적으로 성찰하고자 하였다. There is not much difference between the literary meaning of maritime novels and that of general literature. The difference that exists, however, lies in the dissimilarity in expressing the spirit of literature and the vindication of universal humanism. So far, Jules Verne’s novels have earned an prominent place in the field of maritime novels, as we recognize it to be so. A new set of understanding, however, is necessary if we take into account that the sea in Verne’s masterpieces is not the actual sea itself, but a sea that has been interpreted. In reality, his maritime novels has been written under a significant premise of ‘What is real is imaginary’ (L’imaginarie c’est le real), and the main themes of his books were journeys, scientific discoveries and establishments of colonies. The problem lies in that those premises and themes have justified a rationale for the imperialism of his period. This perception questions his novel’s high reputation and requires a new approach in understanding maritime novels. So far, our maritime novels have been overly biased in its perception of the sea. Therefore, we have paid little attention to the diverse aspects that maritime novels have demonstrated. Main characteristics pertaining only to the maritime novels have been largely overlooked, and complex and multi-layered relationships reflected in the pieces were dealt with ease. Many lives arise at the point where man and sea meet, but with the eyes that we used to look at ‘terra firme’, we may not fully perceive them. Moreover, those lives may not remain as it is, but transform anew our inner life. This research focused on the problems of our maritime novels that have concentrated heavily on the writer’s neighborhood or experience over the sea. These problems are burdens that we can’t escape from, but also a start point where we could explore diverse paths of development. Through those efforts, the research did not fail to discuss on the current state of our maritime novels. It also distinguishes maritime novel’s unique literary aspect by reviewing few pieces worthy of special attention. Eventually, the research intended to provide an opportunity to systematically and completely reflect the life that has been endowed by our cultural tradition and history that have begotten maritime novels.
