  • 수자원설계 및 계획 시 제한된 강우자료로 인해 나타나는 한계를 개선하기 위한 목적으로 추계학적 강수모의 모형을 활용한다. 대표적인 추계학적 강수모형으로 Bartlett-Lewis Rectangular Pulse Modified Model(BLPRM)과 Neyman-Scott Rectangular Pulse Model(NSRPM) 등이 활용되고 있으며, 관측강수량의 통계적 모멘트를 재현할 수 있도록 모형 매개변수를 최적화하는 과정이 필수적으로 요구된다. 기본적으로 모형 매개변수들의 조합을 통해 추정되는 통계적 모멘트와 관측값의 통계적 모멘트를 반복적으로 비교하면서 최적 매개변수를 추정하게 된다. 그러나 상대적으로 적은 관측값을 이용하여 매개변수를 추정하기 때문에, 매개변수 추정이 어려울 뿐만 아니라 매개변수의 불확실성도 큰 특징을 가지고 있다. 모형 매개변수 추정과정에서 다양한 목적함수가 활용되고 있으나, 고려되는 통계적 모멘트가 평균 및 분산 등 2차 모멘트에 제한되고 있어 극치강수량에 대한 재현성은 상대적으로 부족한 부분이 있다. 본 연구에서는 3차 모멘트를 포함한 목적함수를 활용하여 NSRP모형 매개변수를 추정하고, 기존 2차 모멘트를 이용한 매개변수 접근방법과 극치강수량 재현 측면에서 비교를 수행하였다. 최종적으로 유역 단위에서 극치강수량 재현효과를 평가하기 위해서는 면적강수량 추정이 매우 중요하며, 본 연구에서는 이러한 점을 감안하여 강우 지점 간의 상관성을 유지하면서 강우모의가 가능한 다지점 NSRP 모형과 연계하여 극치강우 재현 가능성을 평가하였다.

  • This paper focuses on Alain Resnais's representative works (1955), (1959), and (1963), and analyzes how he implements a representation of memory though cinematic apparatus. These three films deal with horrific memories that seem impossible to reproduce aesthetically such as the Holocaust, the Hiroshima Atomic Bomb, World War II, and the war in Algeria. The reappearance of events that stripped humans of even their minimum dignity can naturally be associated with ethical issues. These events can never be reproduced because they cannot be explained in the human language. It is also impossible to reproduce in a way that doesn't invade other peoples' sufferings, nor displays the pain of others as spectacles. Alain Resnais was a director who realized that if factual representation was not possible from the beginning, truthfulness would have to be approached through cinematic form. Therefore, he tries to overcome these problems through cinematic forms. First, he shifts to action films to avoid the obscenity of documentary. shows the records of camps captured by German forces in the past, while shows the pain of others in a fictional form of representation. Next, he describes how the trauma affects the identity of the main character through a flashback in , but also shows a main character who is experiencing trauma without a flashback in Flashbacks have the effect of showing the effects of trauma on the main character, but at the same time they involve the obscenity of enjoying the suffering of others. Nonetheless, the absence of flashbacks highlights the impossibility of representation. This is because it is not silent in the impossibility of representation but is constantly approaching. The attitude that repeatedly circles around impossibility is an ethical form that maximizes the impossibility of representation. In conclusion, this is the ethics of representation that Alain Resnais showed in his films.

  • In order to precisely determine the vertical displacements of CORS antenna phase centers caused by their replacement, intensive research has been carried out in this paper throughout processing GPS measurements made before and after the events. After applying the estimated displacement in the data processing, results show that coordinate repeatability of the vertical component is able to be 7.9mm on average. Comparing with results (e.g., 23.5mm) without applying the displacement, it was possible to conclude that these accuracies are significantly improved, which is equivalent to those before the event of the replacement.

  • The purposes of this study is to analyze the effects of repeated mountain trekking experience in adolescent sociality. Fifty-eight adolescents who took part in Baekdu-daegan trekking program were analyzed as research subjects. The subjects were divided for comparative analysis. Those who participated 40 times or more from 2014 to 2015 were designated as repetitive participants, and those who participated 5 times or fewer from March 2016 to April 2016 were designated as temporary participants. The general attributes of the subjects were examined by using descriptive analysis. A correlation analysis was carried out to compute the correlation coefficients between the five sub-components of sociality, and an independent sample t-test was executed for comparative analysis of sociality. The results of the analysis showed that sociality was higher in adolescents who repeatedly participated in trekking. Repetitive participants scored higher than temporary participants in all measures of the sub-components of sociality: autonomy, lawfulness, diligence, cooperativeness, and interpersonal relationships. We have verified positive influence of repetitive trekking experiences based on the research results thus far. Therefore, it supports the need of forest education as a fundamental approach to solving adolescent problems.

  • Elastography utilizes the fact that the tissue of a malignant tumor is harder than that of a benign tumor and increases the specificity of diagnosis according to the elastic modulus of the tumor, helping to reduce unnecessary biopsies. However, the reliability of elastography can be influenced by the equipment used and the examiner's skills. In this study, the researchers analyzed the reproducibility of elastography by evaluating phantom images when measuring the elasticity values repeatedly. Phantoms were created using silicone and gelatin with different levels of stiffness, and they were inserted at varying depths from the surface. The elasticity values were measured using shear wave elastography. The study aimed to determine whether the reproducibility of elasticity values remains consistent depending on the stiffness and depth of the lesions. The experimental results showed that there was no statistically significant correlation between the elasticity values obtained through shear wave elastography and the depth or stiffness of the lesions. However, in the lesions with the lowest stiffness, the elasticity values were statistically significant (p<0.001) and showed a high correlation with the depth of the lesions. Although there were variations in the measured elasticity values based on the differences in lesion stiffness and depth, these differences did not significantly impact the diagnosis. Therefore, shear wave elastography remains a reliable diagnostic method, and it is suggested that it can be helpful in the diagnosis of breast lesions.

  • Color Doppler imaging(CDI) was carried out to determine CDI-derived resistive index(RI) values of normal canine ophthalmic vasculature and its reproducibility. CDI was performed on 58 dogs. and normal ranges of RI value were calculated for the medial long posterior ciliary artery(mLPCA), ciliary artery(CA), and ophthalmic artery(OA). Ophthalmic vascular RI values of normal dogs were 0.67$\pm$0.07, 0.70$\pm$0.06, and 0.80$\pm$0.04 in mLPCA, CA, and OA, respectively. Means of RT value of all vessel had no statistically significant difference by sex, fellow orbits, and skull type. The results suggest that color Doppler imaging is a noninvasive test which has the advantage of providing objective measurements of blood flow velocity parameter in the canine eye and orbit.

  • American superhero comics are being produced in numerous different forms for multiple, and cross-platform media. In cinema, films based on superhero comics top the list of all time box office records. The same phenomenon of the 'Invasion of Superhero' is duplicated in Korean box office 2012, however, the korean fans are not familiar with the superheroes from the publication which provides the original source of characters and stories for other superhero related media products. Based on observing the multiple and vastness of world building characteristics of superhero comic, this paper attempts to associate the continuous creative nature and the infinite repetition of superheroes and comic texts with the identity of superhero on ontological level. First, chapter 2 examines how one superhero exists in multiple and different worlds individually by utilizing the concept of 'multi-universe' or 'multiverse' in comic texts. Initially, duplicating a superhero on multiple settings and series destroyed continuity and allowed contradiction and paradox confused narrative as a whole, but it also gave chances for comics to be more vibrant and experimental with their stories and characters. Chapter 3 analyzes the superhero comic texts in the light of repetition, concept developed by french philosopher Gilles Deleuze, and make the argument that the superheroes and texts are not repeated to generate surplus of source for economic utilitarian purposes, but it is, first and foremost, a repetition of creativeness and capability. Many concepts introduced by Deleuze in his early masterpiece, $\acute{e}$rence et R$\acute{e}$p$\acute{e}$tition> are taken to support this argument. Mainly, his critical views on generality of the identity and his effort to replace the Plato's system of representation with vibrant creative, and renewal energy of r$\acute{e}$p$\acute{e}$tition. According to Deleuze, repetition is similar concept, if not identical, to what Nietzsche called the 'eternal return' which allows the return of the Overhuman or the Superhuman, and he extends his idea that the returning Overhuman is the singular simulacre which opposes the generalization of identity, in the likes of Plato's Idea. Thus, the superhero's identity is ever changing, ever returning, and ever renewing Overhuman. The superhero must be repeated to fully actualize his/her existence. Also, based on Deleuze's reading of Bergson's texts on the Virtual, the superhero, for example Superman, is actualization of his/her multiplisit$\acute{e}$, the internally multiple, and differentiated variations from itself. These every Supermans' multiplisit$\acute{e}$ shares common memory, past, and duration, thus the Virtual of Superman. Superman becomes himself only by actualizing the movement and differentiation from these multiplisit$\acute{e}$ in his virtual on the surface of reality. On chapter 4, a popular Korean comic book character Oh, Hae-Sung's r$\acute{e}$p$\acute{e}$tition and multiplist$\acute{e}$ are analyzed, and makes comparison to that of Superman to distinguish the repetition from r$\acute{e}$p$\acute{e}$tition, and multiplicit$\acute{e}$ from diversity.

  • A number of methods have been developed to determine sample sizes in clinical trial, and most clinical trial organizations determine sample sizes based on the methods. In contrast, determining sufficient sample sizes needed for experiments using microarray chips is unsatisfactory and not widely in use. In this paper, our objective is to provide a guideline in determining sample sizes, utilizing reproducibility of real microarray data. In the reproducibility comparison, five methods for discovering differential expression are used: Fold change, Two-sample t-test, Wilcoxon rank-sum test, SAM, and LPE. In order to standardize gene expression values, both MAS5 and RMA methods are considered. According to the number of repetitions, the upper 20 and 100 gene accordances are also compared. In determining sample sizes, more realistic information can be added to the existing method because of our proposed approach.

  • Gas chromatography using sulfur chemiluminescence detection (GC-SCD) which exhibits very good selectivity, linearity, and sensitivity was applied to the analysis of suIfur compounds in gaseous fuel. The expectmental method used in this study was to resolve the problems of repeatability and reproducibility by means of the adsorption of sulfur compounds, which is different from the existing analysis method of these compounds by GC-SCD. The calibration curves of the standard gases including dimethyl sulfide, t-butylmercaptan and ethyl methyl sulfide exhibited an excellent linearity. As the result of precision tests for the above three compounds, the high reproducibility for tests showed while repeating three times during four days, respectively. In addition, the coefficient of variation was less than 3%. In consequence, the expectmental method of this study is very effective not only with low uncertainty but also with better accuracy, which can quickly determine the concentration of gas odorants in LPG (Liquefied Petroleum Gas) from oil reservoirs and filling stations.
