An optimal design of the gas generator for Liquid Rocket Engine (LRE) was conducted. A fuel-rich gas generator in open cycle turbopump system was designed for 10ton in thrust with RP-1/LOx propellant. The optimal design was done for maximizing specific impulse of thrust chamber with constraints of combustion temperature and for matching the power requirement of turbopump system. Design variables are total mass flow rate to gas generator, O/F ratio in gas generator, turbine injection angle, partial admission ratio, and turbine rotational speed. Results of optimal design provide length, diameter, and contraction ratio of gas generator. And the operational condition predicted by design code with resulting configuration was found to maximize the objective function and to meet the design constraints. The results of optimal design will be tested and verified with combustion experiments.

This paper suggests methods to chronicle and track the history of dialogues exchanged among characters to prevent logical errors of a story. As for stories that are long with many characters, especially in full-length novels and co-written stories, cognitive burden is imposed on a writer. If the writer has confused understanding of a character, then a logical error would enter the story. This would compromise completeness and integrity of writing. Against the backdrop, this paper shows how dialogues among characters are chronicled and tracked by using the aforementioned tracking methods through design of a writer support system that relieves a writer's cognitive burden while supporting the writing and through an analysis of existing novels. In addition, we showed the accuracy results of average 68.5% through the performance evaluation of the query used in the dialogue history tracking.

This research studies the specific cases of Ryusuke Hamaguchi's re-arrangement of the original novel Net emo Samite mo(2010) by Tomoka Shibasaki to his 2018 film Asako I&II. The study focuses on the difference that has been made between the original novel and the film, which occurred after Ryusuke adapted the novel's "Telling" to the film's "Showing." The presence of the passive protagonist and the repetitions are the elements that have been avoided from the traditional Screenwriting theory for a long. Instead of avoiding it, Ryusuke Hamaguchi inherits these traits of the original novel when re-arranging to his film. Despite the presence of a passive protagonist, Hamaguchi's method of adaption increases the attention of the audience by using the other tools of Hollywood's tradition: the use of goal and want of the protagonist. In addition, Hamaguchi's storytelling strategy captivates both the modern cinema audiences and the classical film audiences by creating a story, which both repetitive structure and normative narrative structure were applied.

This paper focused on the narrative and theme of which is one of the different versions of when published in 1910's as a modern printing. Generally researchers regarded different version as a means of research for finding best version. But this paper aimed at the characteristics of different version . This version kept in mind for play(drama), so we could easily find the purpose of change for scenario. 'Yeon-jeong' in is 연정(演訂) in Korean words in Chinese characters. It is sure that this word means that the text considered play(drama). The narrative of also told us that this old novel aimed at the stage. Tendencies are classified four features, first, abundant situation description, second, frequent direct conversation, third, concrete description about direct conversation, fourth, showing poem and appeal for audience. The theme of has an interesting differences in comparison to the group of best version. When main character awakened, this novel showed the most important message. In the group of best version, he awakened to the cloud that he couldn't distinguish anything. But in this novel, cloud didn't appear, in other words, didn't change the scene. Instead, main character realize himself that he changed from Yang-so-yoo to Seong-jin. It is probable that change of process to conclusion aroused reader and audience's sympathy. To sum up, we could know that this novel kept in mind for play(drama).

This study was conducted to present the stylistic differences between Arthur Conan Doyle and Agatha Christie, famous as writers of classical mystery novels, through data analysis, and further to present the analytical methodology of the study of style based on text mining. The reason why we chose mystery novels for our research is because the unique devices that exist in classical mystery novels have strong stylistic characteristics, and furthermore, by choosing Arthur Conan Doyle and Agatha Christie, who are also famous to the general reader, as subjects of analysis, so that people who are unfamiliar with the research can be familiar with them. The primary objective of this study is to identify how the differences exist within the text and to interpret the effects of these differences on the reader. Accordingly, in addition to events and characters, which are key elements of mystery novels, the writer's grammatical style of writing was defined in style and attempted to analyze it. Two series and four books were selected by each writer, and the text was divided into sentences to secure data. After measuring and granting the emotional score according to each sentence, the emotions of the page progress were visualized as a graph, and the trend of the event progress in the novel was identified under eight themes by applying Topic modeling according to the page. By organizing co-occurrence matrices and performing network analysis, we were able to visually see changes in relationships between people as events progressed. In addition, the entire sentence was divided into a grammatical system based on a total of six types of writing style to identify differences between writers and between works. This enabled us to identify not only the general grammatical writing style of the author, but also the inherent stylistic characteristics in their unconsciousness, and to interpret the effects of these characteristics on the reader. This series of research processes can help to understand the context of the entire text based on a defined understanding of the style, and furthermore, by integrating previously individually conducted stylistic studies. This prior understanding can also contribute to discovering and clarifying the existence of text in unstructured data, including online text. This could help enable more accurate recognition of emotions and delivery of commands on an interactive artificial intelligence platform that currently converts voice into natural language. In the face of increasing attempts to analyze online texts, including New Media, in many ways and discover social phenomena and managerial values, it is expected to contribute to more meaningful online text analysis and semantic interpretation through the links to these studies. However, the fact that the analysis data used in this study are two or four books by author can be considered as a limitation in that the data analysis was not attempted in sufficient quantities. The application of the writing characteristics applied to the Korean text even though it was an English text also could be limitation. The more diverse stylistic characteristics were limited to six, and the less likely interpretation was also considered as a limitation. In addition, it is also regrettable that the research was conducted by analyzing classical mystery novels rather than text that is commonly used today, and that various classical mystery novel writers were not compared. Subsequent research will attempt to increase the diversity of interpretations by taking into account a wider variety of grammatical systems and stylistic structures and will also be applied to the current frequently used online text analysis to assess the potential for interpretation. It is expected that this will enable the interpretation and definition of the specific structure of the style and that various usability can be considered.

This report documents a case of paraplegia which apparently occurred following epidural injection of triamcinolone (40 mg) and 0.125% bupivacaine(10 ml). The patient's condition was progressive until she experienced paraplegia and dissociative sensory loss below T5(Rt) and T10(Lt) dernatomes, along with urinary and fecal incontinence lasting 24 hours. CT and MRI were normal. Three months after the onset of paraplegia, the patient could only slightly move her legs. After 8 months of the initial paraplegia, she was able to walk with assistance, and to perceive pinrick sensation in her right leg, and tingling in her left leg. She could also void and defecate. At 16 months, paraplegia and sensory loss were slightly recovered. The cause for this paraplegia is still unknown, but it may be from exacerbation of preexisting disease, acute transverse myelitis, anterior spinal artery syndrome, or neurotoxicity.

This study aims to analyze the post-humanistic imagination that has emerged as a major academic thesis in Korean literature, especially novels. In particular, this paper focuses on Cho Ha-hyung's two novels Chimera's Morning(2004) and A Prefabricated Bodhi Tree(2008), published in the early 2000s, for intensive analysis. Post-humanism can be seen as an extension of post-modernism that tried to overcome the limitations of modernity and seek to establish a new world view. In particular, this thought pays attention to the comprehensive understanding of how the rapid development of science and technology, which has developed since the 20th century, has changed the view of humanity and human-centered civilization itself. At the concrete level, it is developing in the direction of constructing a new subject idea by reflecting and dismantling Western-, reason-, and male-centered power mechanisms that are the core of modern civilization. Cho attempts to discover and re-illuminate the surrounding figures, non-humans, and objects that were not noticed in the classic works written in the past. This ideological flow reflects the fact that the concept of human beings, which had been dominated by the humanities in recent years, has been completely changed, and the natural science and technology perspective is applied to the discourse field in various ways. From the point of view of post-humanism, objects that have not been classified as humans and objects that were considered inferior to humans should be included in human or comparable levels. These questions generate interdisciplinary research tasks by involving the large categories of philosophy, such as ontology, epistemology and empirical fields, as well as calling for the participation of the entire literature, science and social sciences. Against the backdrop of a disaster-hit world, Chimera's Morning and A Prefabricated Bodhi Tree depict human beings as variants transformed by bio-technology, and creatures made out of the artificial intelligence built by computer simulations. Post-humanistic ideas in Cho's novels provide a reflective opportunity to comprehensively reconsider the world's shape and human identity reproduced in the text, and to re-explore boundary lines and hierarchy order that distinguish between human and non-human.

Speech database is an indispensable part of speech research. Speech database is necessary to use in speech research and development processes, and to evaluate performances of various speech-processing systems. To use speech database for common purpose, it is necessary to design utterance list that has all the possible phonetical events in minimal number of words, and is independent of tasks. To meet those restrictions this paper extracts PBW set from large text corpus. Speech database that was constructed using PBW set for utterance list and its properties are described in this paper.

재난발생 시 유관기관 간, 유관기관과 개인 간, 그리고 개인과 개인 간 재난대응에 필요한 정보를 적시에 주고 받는 것은 피해 규모를 줄이는데 결정적인 역할을 한다. 지금까지 재난상황에서 사용되었던 기존의 커뮤니케이션 수단은 TV, 라디오, 공공기관 통신망 등이었다. 그러나 TV나 라디오는 해당 기기가 주변에 없거나, 개인과 개인 간 정보 교환 시, 그리고 관련 통신망 자체가 무력화된 상태 등에서는 활용에 제한을 받게 된다. 또한 소방통신망 등 유관기관들이 사용하고 있는 통신망의 경우에도 재난의 종류에 따라 그 활용 폭이 달라질 수 있고 일반 대중에게 정보를 전파할 때는 사용할 수 없다는 단점도 존재한다. 이런 상황에서 최근에 급격히 발달하고 있는 모바일 네트워킹 기술은 재난대응 커뮤니케이션과 관련하여 새로운 돌파구를 제시하고 있다. 기존 커뮤니케이션 수단들과 달리 스마트폰 등의 모바일 기기들은 민(民)과 관(官)을 구분하지 않고 이미 거의 모든 개인이 소유하고 있는 상황이며, 이를 활용하여 항시 인터넷에 접속할 수 있는 환경이 구축된 상태다. 따라서 모바일 환경에 적합한 재난대응 커뮤니케이션과 관련한 연구동향을 정리하고 새로운 과제를 도출해 낼 필요가 있다. 본 논문에서는 크게 1) 모바일 네트워크 기반의 재난대응 어플리케이션 개발에 관한 연구와 2) 모바일 환경에서 소설 네트워킹 서비스를 활용한 재난대응 커뮤니케이션이라는 두 개의 주제를 중심으로 최근 연구동향과 향후 과제를 제시하고자 한다.
