태양과 달 그리고 지구의 비대칭 중력장에 의해 발생하는 다양한 섭동항은 정지궤도 위성의 위치를 지속적으로 변화시킨다. 따라서, 정지궤도 위성의 위치를 일정한 범위 내로 유지시키기 위해서는 궤도경사각과 승교점 적경을 조정하는 남북방향 위치유지와 이심률과 경도를 조정하는 동서방향 위치유지가 필요하다. 본 논문에서는 통신해양기상위성 비행역학 소프트웨어를 이용하여 통신해양기상위성의 위치유지 시뮬레이션을 수행하고 그 결과를 분석하였다. 통신해양기상위성은 경도 $128.2^{\circ}E$ 에서 위성을 ${\pm}0.05^{\circ}$ 범위 내에 유지시키기 위해 일주일 주기로 동서/남북방향 위치유지를 수행하며, 위성의 남쪽 패널에만 부착된 태양 전지판으로 부터 발생하는 자세오차를 줄이기 위해 하루 두 번 휠 오프로딩을 수행한다. 본 논문에서는 휠오프로딩을 고려한 위치유지 시뮬레이션을 수행하였고, 그 결과 통신해양기상위성 비행역학 소프트웨어를 이용하여 통신해양기상위성을 ${\pm}0.05^{\circ}$ 범위 내에서 안정적으로 유지시킬 수 있음을 확인하였다. 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.

김해연 ( Hae Yeon Kim ) 한국외국어대학교 언어연구소 2010 언어와 언어학 Vol.0 No.49

This research is a corpus-based exploration of the metaphorical meanings of elkwul ``face`` in Korean from the perspective of cognitive linguistics. It first discusses the frequency of elkwul in the corpus in terms of types of modifiers. It also characterizes meanings of elkwul in five categories. Second, among various meanings elkwul, this study focuses on the metonymical and metaphorical uses of elkwul, examining nouns which coocuur with elkwul. Third, this research investigates metaphorical extension of the meanings of elkwul, showing that such extension is based on metaphorical schemas of a face as a body part, showing the embodied nature of language. Finally, this research proposes that a corpus-based cognitive approach is useful in characterizing the metaphorical extension of the meanings of body-part terms in Korean.

This research investigates the meanings and uses of ttattushata ``warm``, one of the adjectives used to signal speaker`s judgement about temperature, through an analysis of a Korean written corpus. First, this study examines the frequency of ttattushata and grammatical forms, showing the dominant attributive usage of ttattushata with the rate of 61.1%. Second, it shows the distribution of meanings of ttattushata by classifying types of nouns co-occurring with ttatushata in attributive and predicative positions. The meanings of ttattushata can be summarized as in the following: (i) denoting mild temperature of weather, concrete objects, body parts, etc. and (ii) showing friendly atmosphere, attitudes, behaviors, etc. Third, after examining the literal and extended meanings of ttattushata, this work characterizes abstract meanings of ttattushata in terms of metaphor theory, showing that the metaphorically extended meanings are derived from the conceptual metaphor that views abstract notions as temperature-transmitting concrete objects by matching concrete objects to abstract notions/entities. Finally, this research claims that a corpus-based approach is a useful tool in characterizing many closely related lexical items in written texts.

This research attempts to explore and compare the uses and meanings of the adjectives tepta and ttukepta ``hot``, two of the temperature-denoting words, through an examination of a Korean written corpus. This research first examines the frequency of tepta and ttukepta, showing that ttukepta is far more frequently used than tepta in the database. Second, it examines the frequency of grammatical functions of tepta and ttukepta, showing that the frequency of ttekepta is much higher in the attributive usage. Third, this study shows that tepta is used to show highness of temperature in weather in most cases, but ttukepta is used to denote not only high temperature in weather but also strong, energetic emotional responses when it co-occurs with action/ activity words or abstract nouns. Fourth, this research explores co-occurrence patterns of the two adjectives, showing that most of the tepta examples are used to modify or predicate weather-related nouns while ttukepta co-occurs with nouns of diverse semantic categories of concrete objects and abstract entities.

김해연 ( Hae Yeon Kim ) 한민족어문학회 2014 韓民族語文學 Vol.0 No.68

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.

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.

This study aimed to categorize women’s body shapes by type after extracting prototypes of 25~34 year old Korean woman. The standardizing research service project conducted by the Ministry of Commerce, Industry and Energy in 2005, divided the age ranges of adult women into three groups: 18~24 years (young), 25~34 years (young-adult) and 35~49 years (adult). This study utilized this age division method to create a concrete body type categorization schema with the most marriageable period, 25 to 34 years old as target age the target age group. We used, measurement data from the 7th Korean Human Body Size Survey (Size Korea) for the body shape analysis. We completed a statistical analysis using the statistical program SPSS 21. After creating the body types using CLO 3D, which is based on the 7th Korean human body measurements, we input data for the average size for each type into the Avata. We then compared and analyzed the cross sections using the Rapidform XOR program. The results of the type-specific characteristics are as follows: big square body of obese body, small square body of plain flat body with tall, plain square body of plain flat with short, triangular body of lower body obesity there was. Significantly, the results of this study should facilitate the development of various apparel products using mass customization or easy-order systems.
