In this study, an artificial intelligence(AI) was developed to help with facial expression practice in order to express emotions. The developed AI used multimodal inputs consisting of sentences and facial images for deep neural networks (DNNs). The DNNs calculated similarities between the emotions predicted by the sentences and the emotions predicted by facial images. The user practiced facial expressions based on the situation given by sentences, and the AI provided the user with numerical feedback based on the similarity between the emotion predicted by sentence and the emotion predicted by facial expression. ResNet34 structure was trained on FER2013 public data to predict emotions from facial images. To predict emotions in sentences, KoBERT model was trained in transfer learning manner using the conversational speech dataset for emotion classification opened to the public by AIHub. The DNN that predicts emotions from the facial images demonstrated 65% accuracy, which is comparable to human emotional classification ability. The DNN that predicts emotions from the sentences achieved 90% accuracy. The performance of the developed AI was evaluated through experiments with changing facial expressions in which an ordinary person was participated.

This study examined the relationship among service quality perceived by consumers according to the types of driving ranges(I: indoor and outdoor), market segmentation, the reason for choice of the driving range, customer satisfaction and loyalty and analyze their causal relationship. To reach this goal, this study conducted a questionnaire research for consumers of driving ranges by dividing it into the indoor and outdoor ranges. The quest-factor analysis(SPSSWIN Ver 13.0), the confirmatory factor analysis and the structural equation modeling method (AMOS 6.0) were used to analyze the data collected for this study. Based on the findings of this study, the following conclusions were drawn: The reason for the choice in both indoor driving and outdoor driving had no direct influence on the customer loyalty, but it had an indirect influence on the customer loyalty through customer satisfaction and service expectation. In addition, the service expectation had a direct influence on the customer loyalty in both indoor driving and outdoor driving. Therefore, the customer satisfaction in both indoor driving and outdoor driving serve as a significant mediating variable to reinforce the relationship between the service quality and customer loyalty.

From 2010, new keyword of so-called devising theatre in the Korean performing arts scene has emerged. The backdrop is the antipathy to the hierarchical creative environment, the search for a language that can reflect increasingly complex societies, and the influx of new performances from abroad. Of course, devising theatre can be realized in a wide variety of forms in the actual field, so it cannot be defined as one methodology. But commonly all these various forms of the attempts aim to create a democratic relationship among participants, and process-centered breakthrough in the hierarchy of creative materials such as texts, sounds. light and human body. In 2017, Creative VaQi seeks to find new keyword called 'Reality of Division in Korean Peninsula' and to develop it into performance languages experimenting inter-disciplinary devising methodology. The company conducted a walking trip alongside the division line(300km) and tried to achieve the landscape and traces of division. After the walking, they created a specific form and performing contents called "Walking Holiday" out of their experiences. In this thesis, I will analyze the whole process of the devising "Walking Holiday" and examine what kind of result it led to. Furthermore, I, as the director of "Walking Holiday" will continue to discuss new possibilities and limitations of devising theatre methods that the company tries and aim at this time.

Akjang yoram 『樂章要覽』 is a book that summarizes only the important contents from the Akjang 樂章. Akjang 樂章 is arranged in the first half, and score 樂譜 is arranged in the second half. It seems that Akjang yoram 『樂章要覽』 passed through a total of four stages through the time when the handwriting and the lyrics were written. The presence of various handwriting and traces of modifications means that it has been passed through by several people, so it is not unrelated to the fact that several traces remain on the back of the cover of Akjang yoram 『樂章要覽』. The first part of the Akjang 樂章 is a method of presenting the name and lyrics of the accompanying music based on the ritual procedure, and in particular, the lyrics are written in Chinese characters and Hangeul sounds to improve readability. The score in the second half complies with the ritual procedures, but boldly omits overlapping melodies, and is composed based on the music, and various symbols are used to capture the expression of court music. This structure is a reflection of the direction we practiced to harmonize with the music after prior ritual procedures and diction. This was a device to increase the efficiency of music education and music practice for the court musician. The characteristics of the musical pieces are that they consist of essential musical pieces that must be mastered as musicians. In addition, the name Kim Hyung-sik 金亨植 is noted on the back cover of Akjang yoram 『樂章要覽』, and he was a court musician who was active in the age of King Sunjo 純祖. In other words, the musical pieces included in Akjang yoram 『樂章要覽』 are the core repertoire played by court musicians like Kim Hyung-sik 金亨植. Akjang yoram 『樂章要覽』 is a 'music practice booklet' containing the daily life of court musicians. Akjang yoram 『樂章要覽』 is a booklet designed for the purpose of teaching the court musicians to sing while correctly pronouncing the lyrics in major ceremonies. It is even more noteworthy in that Kim Hyung-sik 金亨植 was an owner. In addition to the fact that Kim Hyung-sik's name remains, and in the practicality of being used by various court musicians reflecting and modifying the changes of the times, it is meaningful in that it contains the path of court musicians who spent a lot of time and time to transmit court music.

In this thesis, Improvisation of Jazz Vocal that can be characterized as Jazz music, namely practice of Scat suggest that way of applied approach that root position of chord and chord tones. Scat plays a solo using reproduced tunes of meaningless scat syllable that is not use the lyrics and melodies, which are written in a score. For this, Using the root position of chord is a reference point that Jazz vocal constructs a musical melody. Singing person can develop that reference point from simple scat to develop increasingly complex scat and can express that musical expression and communion. It analyzed the music functionally with a standard Jazz music 'All of me' as the center from composition of chord tone that improvise song to bass line, bass scat, analysis of chord tones arpeggio and expression. In this thesis, the improvisation of a Jazz vocal that may seem somewhat abstruse and complex could be relatively easy to construct through a gradual approach.
