Various perturbations by the sun, the moon and the earth itself cause a continuous change in nominal position of a geostationary satellite. In order to maintain the satellite within a required window, north-south station keeping for controlling inclination and right ascension of ascending node, and east-west station keeping for controlling eccentricity and longitude are required. In this paper, station keeping maneuver simulation for Communication, Ocean and Meteorological Satellite (COMS) was performed using COMS Flight Dynamics Software(FDS) and the results were analyzed. COMS performs weekly based east-west/north-south station keeping to maintain satellite within ${\pm}0.05^{\circ}$ at the nominal longitude of $128.2^{\circ}E$. In addition, COMS performs wheel off-loading maneuver twice a day to eliminate attitude error caused by one-solar wing in the south panel of the satellite. In this paper, station keeping maneuver considering wheel off-loading maneuver was performed and the results showed that COMS can be maintained well within ${\pm}0.05^{\circ}$ window using COMS FDS.

Opera is the most comprehensive musical art. In recent years, contemporary opera worlds has seen a variety of attempts to reinterpret operas of the past in a modern light. This has resulted in a dramatic change in the production of musical style and stage art. The purpose of the study was to modernize and streamline opera costumes by extending the scope of existing stage costume design, through the reinterpretation and application of the decorative elements in the Middle Age of Rococo, such as ruffles, frills, shirring, embroidery, buttons, etc., in such a way as to effectively communicate the moods of an opera to a modern audience. The costumes of the Rococo period were reinterpreted in a modern way, with the following results. First, in this work, the male main character was played by a bass to express the image of an older, lazy, rich man. A key element in modernizing the stage costume was selection of the costume color in such a way as to visually represent the voice tones sung by the major characters in the opera. Second, the maid hat and aprons were decorated with frills by applying the curves of Rocaille decoration from the Rococo period symbolize the role of the maids. This represented the distinction between occupation according to class and status at that time, while also expressing the ideals of modern feminine beauty. This makes for more comfortably-worn costumes, and is economical for production expenses. In the future, the stage costume design for classical opera will need to be revised consideration of a modern viewpoint.

Cryptosporidium parvum oocysts and Giardia lamblia cysts were chlorine-resistant pathogenic microorganisms and were not treated effectively by a single step application of common chlorine-bases disinfectants. Studies on alternative disinfection processes such as gamma ray and E-beam for chlorine-resistant pathogenic microorganisms have been performed. The disinfection efficiency of B. subtilis spore after gamma ray was 99.4% at 2kGy. C. parvum oocysts treated with E-beam was observed with Transmission Electron Microscope. The results showed that the radiation technology is very effective for the disinfection of protozoa such as Cryptosporidium parvum.

This paper examines Choi Myung-ik`s collection of essays, “an idea about writing,” which contains his nineteen essays. Reflected in this collection are not only his idea about writing but trends in the North Korean literary circles and political change, of the day and his literary response to them. Nevertheless, very little study of Choi Myung-ik`s essays has been done. The concern for and product of study of, North Korean literature have been profound as soon as the ban on it was lifted, but until recently, most studies of Choi Myung-ik have been restricted mainly to his novels. This paper is based on this problem recognition. In the second chapter, the essays in “an idea about writing” are organized and summarized in order. These nineteen essays are far from self-confessional ones, but this study may contribute to widening range of study of Choi Myung-ik in the respect that the number of essays outgoes that of his novels. The third chapter examines the first eight essays of the collection. They directly reflect the flow of the North Korean literary world and political transformation during both the period of post-war reconstruction work and foundation construction for socialism(1953-1960), and the period of over-all building of socialism and Chollima Movement(1961-1966). Through this examination we`ve come to see the party line of North Korea during each period and Choi”s literary response to it. In the fourth chapter, Choi”s linguistic sense and spirit of writing are analyzed, centering on the second half of the collection. We can recognize his great effort for correct usage of our language and words through his confession, “each word seemed to awaken different feelings physically as well This paper examines Choi Myung-ik”s collection of essays, “an idea about writing,” which contains his nineteen essays.

Through this examination we`ve come to see the party line of North Korea during each period and Chol`s literary response to it. In the fourth chapter, Choi`s linguistic sense and spirit of writing are analyzed, centering on the second half of the collection. We can recognize his great effort for correct usage of our language and words through his confession, “each word seemed to awaken different feelings physically as well as emotionally in accordance with its accuracy and inaccuracy.” Though Choi Myung-ik criticized sharply the limitation and violence of colonial modernity before liberation, he took a step forward the center of North Korean literary circles and thus his world of literature also could not but change after liberation. He found the positive image of the people and described it in the form of historical novels with the purpose of “admiration for the people.” Choi Myung-ik consistently attempted to embody “admiration for the people” in his historical novels whose roots he found in the ethos of “uiri”(loyalty) of our nation. He thought that this very “uiri” connoting the self-consciousness of the subject was the driving force of the people-centered history. However, in the wake of dramatic changes of North Korean literary circles since 1960s his literary theory of “admiration for the people” lost its footing and then he vanished into thin air.

Critical discourse analysis (CDA) has analyzed journalistic discourse in terms of power and ideology, and it has shown how dominance relations are maintained in society. This research investigates power and ideology expressed in the use of cwuntong(hata) ``stirring, commotion in secret`` from the perspective of CDA. It first presents a brief overview of CDA to explore the possibility of applying CDA to text analysis. This study investigates cwuntong(hata) in media discourse, showing the contexts where the word is used. Examination shows that there is always a distinction between the self and the other (party) when cwuntong(hata) is used. Based on such an ideological dichotomy, writers evaluate the other party`s actions/events in terms of their own value systems. Such a distinction is shown in the following categories: (i) leftist and rightest powers in Korean society, (ii) South and North Korean politics and policies toward each other, (iii) Islam rebels and international terrorism, (iv) speculation powers in economy and stock markets, (v) Paduk games, among others. Finally, this research suggests that investigation of ideologically oriented words or phrases is useful in characterizing the nature of a given text, and that CDA is a useful tool for analyzing media discourse texts.
