텍스트의 스토리를 자동으로 이해하기 위해 텍스트에서 기술된 사건(event)을 파악하고 이들을 조합하여 스토리가 어떻게 구성되어 있는지를 파악하는 연구들이 진행되어 왔다. 하지만 이는 스토리의 깊은 의미론적 이해를 요구하는 것 이외에도 텍스트마다 상황과 일어나는 사건들이 다양하기 때문에 언어 자원이 부족한 환경에서의 처리에는 한계가 있다. 이러한 문제는 사건들을 추상화 하여 단순하게 표현할 수 있다면 스토리 이해의 자연스러움을 저해하지 않고 해결 할 수 있다. 본 논문에서는 사건들의 추상화 과정을 위한 기초 연구로서 텍스트 속 등장인물이 행하거나 당하는 사건들을 추출하여 PMI기법을 통해 사건의 흐름을 파악하고 언어학적 단서를 참조하여 스토리 이해 과정에 누락될 수 있는 사건들을 추가하여 보완하였다. 이러한 접근을 통해 등장인물이 행할 수 있는 사건들을 재구성하여 단순화하는 방법을 제시한다.

To detect islanding mode when the grid is being tripped is a major safety issue in the Utility Interactive Distributed Generation (UIDG) system. In this paper, analytical design method is suggested for AFD & RPV method under IEEE929-2000 recommended islanding test condition. We have discussed that there is a same point. we injected reactive component of the current by AFD & RPV methods, but the current reference generated is other waveform. Possible if amount of reactive components in this methods are same each method, there is happened same rates frequency variation. To verify the validity of the analytical comparison, this paper presents simulation and experimental results from single phase, 3[kW] inverter for the transformerless UIDG system.

This thesis is written to point out the fact that story-teller has to be also appointed to intangible cultural treasure. For this, I compared the birth tales of king keum-wha and al-yeung with ghene-gid-dang dangshin(house-ghost) Bonpuri in Che-ju Island and the place name yeun-gi tale in Yong-ghe-won, Whan-ju gun, Cholla-buk-do. And, I examined that the latter oral narratives are very useful to interpret the meaning of the former documents. Besides, using the In-ju tale(人柱傳說), I clarified that Oral narratives reflect the Korean people's consciousness structure. Through all these, I elucidate oral narratives have the value as cultural treasure. Consequently, I maintain the professional story-tellers have to be appointed to intangible cultural treasure.

This study focused on the spirit to becoming the true "I" as a human, and it attempted to pay attention to the "images" sent by the unconscious to prompt the reality of that spirit. The purpose of this study was to identify the symbols in myths and folk tales that appeared in the individual's dreams and to shed light on how the universal experiences of humankind are re-experienced and integrated into an individual's life. This study used a total of 105 mandala paintings collected through the researcher's own dreams from February 2019 to September 2020. Among them, repeated symbols were classified into basic shapes, squares, crosses, triangles, circles, and spirals, as suggested by Riedel. The study truthfully described the discovery of a practical layer of psychology as a human's individualization and changing, resulting in autoethnography, which is a type of qualitative study.

Radio relics, Mpc-size elongated diffuse radio emissions found at galaxy cluster outskirts, are known as the result of shock acceleration during the cluster merger. Theories have claimed that low Mach number shocks are too inefficient to create the observed properties of radio relics. Alternative scenarios such as fossil cosmic ray electrons (CRes) from AGNs are required to explain the observations. However, how exactly the fossil CRes from AGNs can supply the Mpc-size radio relic is still an open question. In this study, we present our recent uGMRT radio observation results of the merging galaxy cluster Abell 514. We found three remarkable AGN jet tails that may have undergone multiple reorientations and extend nearly 800 kpc. Using multi-frequency data, we have performed spectral analysis along the AGN tails and track how the tails lose or gain energy as they propagate in the intracluster medium. We will discuss whether these AGN jets can provide sufficient seed CRes to radio relics.

This paper surveys recent multiagent reinforcement learning and neural Myerson auction deep learning efforts to improve mobility control and resource management in autonomous ground and aerial vehicles. The multiagent reinforcement learning communication network (CommNet) was introduced to enable multiple agents to perform actions in a distributed manner to achieve shared goals by training all agents' states and actions in a single neural network. Additionally, the Myerson auction method guarantees trustworthiness among multiple agents to optimize rewards in highly dynamic systems. Our findings suggest that the integration of MARL CommNet and Myerson techniques is very much needed for improved efficiency and trustworthiness.

Frequency resource value is growing more and more with the development of the wireless communication. With the advent of the current information society comes a serious shortage of frequency resource, as the amount of supply is far from meeting its demands. Thus, cognitive radio (CR) technique is receiving more attention as a way to make use of the temporarily unoccupied frequency resource. In this paper we propose a novel out-of-band spectrum sensing and dynamic channel access scheme for frequency hopping-based cognitive radio ad-hoc networks. At the beginning of each current channel hopping time, member nodes perform spectrum sensing for the next hopping channel. Based on the proposed collision free primary detection notification, member nodes can determine whether they should execute a hopping time extension procedure of the current channel or not. When the primary detected hopping channel is re-idled, the hopping pattern recovery procedure is performed. In this paper we evaluated the performance of the proposed dynamic sensing and hopping channel extension mechanism for the various wireless network conditions. As a result, we show that the proposed method can increase channel utilization and provide reliable channel management operation.

This study aims to extract and analyze the bibliotherapeutic values/situations of Korean folk-tales for multi-cultural families in Korea. By analyzing 27 stories in the Korean folk-tale picture book written in two languages(Korean & English), we can find out 5 kinds of situational analysis as follows: (1) There are more men than women by the biological sex factor, whereas there are more adults than younger persons by the biological age discrimination. (2) For the space concept, there are a lot of socially related stories in their surroundings. (3) In the vertical relationship, there are more conflict elements than in the horizontal one. (4) There are more helpers from the outside than in the inside circle for the solution of their problems. (5) As a story theme, greed, wisdom, belief and family component elements are greatly involved in the stories. Among their beliefs, there are a lot of wisdom and greed themes, while piety and royalty to parents and conflict against stepmothers are among the family components. All of these would be an archetype of Korean culture, which can play an important role not only to understand Korean lifestyle for the multi-cultural families, but also to learn and practice bibliotherapeutic values.

The purpose of this study is to figure out the effects of multimedia fairy tale and narrative fairy tale lectures on children's language expression ability and drawing representation ability. To achieve this, this study was conducted from March to April, 2011 with 50 five-year-old children(25 children in the experimental group and 25 children in the comparative group) in K and S kindergartens at D metropolitan city. The results were as follows. First, the score of children's language expression ability was higher in the multimedia fairy tale lecture group than in the narrative fairy-tale lecture group. Second, the score of children's drawing representation ability was higher in the multimedia fairy tale lecture group than in the narrative fairy-tale lecture group. As for findings stated above, educational activities with multimedia were important in early childhood education. Consequently, children can better understand stories through multimedia fairy tales and various language activities, and improve their language expression ability and drawing representation ability through the process of exploring and drawing heroes in fairy tales. However, they have more need of educational activities, which are complementary to the merit of narrative fairy tale, than educational activities for only multimedia fairy tale lecture.
