This thesis aims to find out the purpose of recording . I tried to understand the reason that the compiler of included this song in the record of King Yuri. The result of tracking the intention of the compiler in this thesis is as follows. I think that was chosen as a symbol of King Yuri's character, especially connected with his inner side. By introducing a hobby that contained the inner side of King Yuri, the compiler implied that his failures and mistakes in subsequent governments stem from human limitations that did not adequately refine his qualities. I think that the compiler who showed the character of King Yuri through only one short song also showed the highest level of enjoying poetry. The enjoyment of literature is a pleasure in understanding the life of someone through literature and bring it back into their lives. In this respect, by pursuing the intend of the compiler, we will be close to the value of the song, .

Information extraction can facilitate the intensive analysis of documents by providing semantic triples which consist of named entities and their relations recognized in the texts. However, most of the research so far has been carried out separately for named entity recognition and relation extraction as individual studies, and as a result, the effective performance evaluation of the entire information extraction systems was not performed properly. This paper introduces two models of end-to-end information extraction that can extract various entity names in clinical records and their relationships in the form of semantic triples, namely pipeline and joint models and compares their performances in depth. The pipeline model consists of an entity recognition sub-system based on bidirectional GRU-CRFs and a relation extraction module using multiple encoding scheme, whereas the joint model was implemented with a single bidirectional GRU-CRFs equipped with multi-head labeling method. In the experiments using i2b2/VA 2010, the performance of the pipeline model was 5.5% (F-measure) higher. In addition, through a comparative experiment with existing state-of-the-art systems using large-scale neural language models and manually constructed features, the objective performance level of the end-to-end models implemented in this paper could be identified properly.

This paper focuses on 'clean(cheong: 淸)' kinds of style terminologies among various style terminologies appearing in Heo Gyun's Seongsushihwa("惺?詩話") and tries to analyze the distinctive points which 'clean(cheong: 淸)' kinds of style terminologies include. In Heo Gyun's Seongsushihwa, 11 of 'clean' kinds of style terminologies, such as "cheonggyeong(淸勁), cheonghryang(淸亮), cheongryeo(淸麗), cheongseom(淸贍), cheongso(淸?), cheongweol(淸越), cheongjang(淸壯), cheongjeol(淸絶), cheongjeol(淸切), cheongchang(淸?), cheongcho(淸楚)," were used. This paper focuses and analyzes 'cheonggyeong(淸勁)', 'cheongjeol(淸切)', 'cheongcho(淸楚)', and 'cheongweol(淸越)' that he suggested through applying to real literary pieces. The result of analysis indicates that 'clean' kinds of style terminologies 'cheonggyeong', 'cheongjeol', 'cheongcho', and 'cheongweol' share the same 1st character 'clean(淸)', yet have distinctive qualities by the 2nd characters. These 4 style terminologies all share 'cheong(淸)' image which means clear and clean, yet each one has the attribute of the 2nd character that indicates each one's individual characteristic. It is apparent that 'Cheonggyeong(淸勁)' reflects the 'gyeong(勁)' image meaning upright and solid and implies poems of poets' steadfast spirit within clear boundary; 'cheongjeol(淸切)' reflects the 'jeol(切)' image meaning either desperation and imminence or pitifulness and sorrow and implies poems of poets' urgent and pitiful emotions within clear and clean boundary; 'cheongcho(淸楚)' reflects the 'cho(楚)' image meaning either delicacy and fineness or slenderness and tenderness and implies poems of poets' beautiful but not luxurious, delicate and tender emotions within clear and clean boundary; and 'cheongweol(淸越)' reflects the image of 'weol(越)' meaning unworldliness and excellency and implies poems, within clear and clean boundary, of excellent appearance and mentality surpassing mundane world. Compared with the 1st character's attributes of the style terminologies which Heo Gyun used, the 2nd characters's attributes do not appear that vivid. Especially, in the case that the 2nd characters have similar meanings, it is not easy to clarify the categories. Indeed, in order to grasp clear and distinctive qualities of style terminologies, the kinds of them need to be initially categorized by the 1st characters, and then sorted by the 2nd characters. In this case, the contents which the 2nd characters of style terminologies indicate should be considered. It is because style terminologies explain both literary pieces' aesthetic qualities and writers' personalities, and because explanations about literary pieces' aesthetic qualities includes not only the conclusive poetic or semantic boundaries which literary pieces' created but also literary pieces' creation processes and expression techniques. Through the style terminologies with Heo Gyun used in Seongsushihwa, it can be aware that he evaluated poems focussing more on the conclusive semantic boundaries that poets' spirits and poems created than expression techniques or creation methods. The overall aspects Heo Gyun's such style criticism has will be checked out in more detail through further studies by examining more materials.

Automatic text classification is a task of assigning predefined categories to free text documents. Its importance is increased to organize and manage a huge amount of text data. There have been some researches on automatic text classification based on machine learning techniques. While most of them was focused on proposal of a new machine learning methods and cross evaluation between other systems, a through evaluation or optimization of a method has been rarely been done. In this paper, we propose an improving method of kNN-based Korean text classification system using heuristic informations about decision function, the number of nearest neighbor, and feature selection method. Experimental results showed that the system with similarity-weighted decision function, global method in considering neighbors, and DF/ICF feature selection was more accurate than simple kNN-based classifier. Also, we found out that the performance of the local method with well chosen k value was as high as that of the global method with much computational costs.

Named entity recognition (NER) seeks to locate and classify named entities in text into pre-defined categories such as names of persons, organizations, locations, expressions of times, etc. Recently, many state-of-the-art NER systems have been implemented with bidirectional LSTM CRFs. Deep learning models based on long short-term memory (LSTM) generally depend on word representations as input. In this paper, we propose an approach to expand word representation by using pre-trained word embedding, part of speech (POS) tag embedding, syllable embedding and named entity dictionary feature vectors. Our experiments show that the proposed approach creates useful word representations as an input of bidirectional LSTM CRFs. Our final presentation shows its efficacy to be 8.05%p higher than baseline NERs with only the pre-trained word embedding vector.

This study examined the nurse images perceived by nursing students. The study was specifically meant to determine what images grade 2 and 3 nursing students had about nurses before and after their clinical practice to define the nurse's image. The selected nursing students were interviewed to obtain their opinions on the definition and necessity of a nurse and what a great nurse should be like as well as their prejudice about nurses, and content analysis was carried out to categorize their statements. As a result, 48 significant statements and 14 categories were selected. The findings of the study might not be generalizable because the subjects in this study were selected by convenience sampling from two different nursing departments located in Gangwon Province and Gyeonggi Province. More concrete and reliable results are expected if more students from more geographic regions are investigated.

Dismissing incompetent public servants started from Ulsan City is spreading to the nation. As part of comprehensive administrative reform in provincial and municipal authorities, such movement is strong to kick out those who are not qualified and incompetent as public servants. It is because citizens have high hope for the change of public officers. Firing incompetent workers started from Ulsan city government was spread to Seoul City government and to the central government. However, other concerning views over kicking out incompetent public workers are very strongly raised. Accordingly, this study examines various opinions and does institutional, legal, and theoretical reviews on the dismissal system of incompetent workers that is widely spread. It examines social significance and problems over the system and suggests its improvements and directions of innovation toward administrative reform.

Weapon, command, and communication system have been continually developed in the Korean military since last several decades. However, it is always asked to make a more effort on improving the ability of combat capability through people in order to achieve and maximize military power. In terms of improving the battlefield leadership, this research focused on ROTC(Reserve Officers'Training Corps), because the training junior officers lays a great foundation on basic strength of the military. This study theoretically and empirically examined the ROTC's quality and effectiveness of leadership. The proposed research model and hypotheses are mainly composed of four factors: personality, esprit de corps, and professionalism as independent variables; leadership effectiveness as a dependent variable. The empirical result revealed that esprit de corps, professionalism, and personality have a meaningful influence on leadership effectiveness. It is suggested that an ongoing training and education program of leadership for ROTC should be applied for achieving a better leadership effectiveness on the battlefield.

Korean is free of omission of sentence elements and modifying scope, so managing it on morphological analyzer is better than parser. In this paper, we propose functional expansion methods of the morphological analyzer to ease the burden of parsing. This method is a longest phrase matching method. When the series of several morpheme have one syntax category by processing of Unknown-words, Compound verbs, Compound nouns, Numbers and Symbols, our method combines them into a syntactic unit. And then, it is to treat by giving them a semantic features as syntax unit. The proposed morphological analysis method removes unnecessary morphological ambiguities and deceases results of morphological analysis, so improves accuracy of tagger and parser. By empirical results, we found that our method deceases 73.4% of Parsing tree and 52.4% of parsing time on average.

Shin Hae-Chul's music opened a new horizon in the Korean pop music market where only popular music is produced and the music of a similar genre or pattern is mainstream, which has dissolved the complaints of the public who longed for new music. He experimented with his musical potential every time he released his work, which received favorable reviews in that he raised the level of Korean pop music. To solve the unstable factors in today's pop music, it is important to appeal to the public by capturing quality work through continued studies and creative activities. In that context, the attitude of "Next" is led by the late Shin Hae-Chul, and his qualities as an artist greatly contributed to the development of Korean pop music. This indicates that if musicians strive to develop themselves, and strengthen their creative ability to make bold and new attempts, Korean pop music will lead to another fashionable "K-pop" and will open up a new horizon.
