This study deals with the effect of online word-of-mouth (OWOM) variables on the box office. From the result of statistical analysis on 276 films with audiences of more than five hundred thousand released in the Korea from 2012 to 2015, it can be seen that the variables showing the size of OWOM (such as the number of the portal movie rater, blog, and news after release) are associated more with the box office than the portal movie rating showing the direction of OWOM as well as variables showing the inherent properties of the film such as grade, nationality, release month, release season, directors, actors, and distributors.

This paper presents a model that supports decision-makers in the Korean film industry to maximize the success of online movies. To achieve this, we collected historical box office movies and clustered them into types to propose a model predicting each type's online box office performance. We considered various features to identify factors contributing to movie success and reduced feature dimensionality for computational efficiency. We systematically classified the movies into types and predicted each type's online box office performance while analyzing the contributing factors. We used automated machine learning (AutoML) techniques to automatically propose and select machine learning algorithms optimized for the problem, allowing for easy experimentation and selection of multiple algorithms. This approach is expected to provide a foundation for informed decision-making and contribute to better performance in the film industry.

According to the current increase of the usefulness of information by Internet Communication network, several methods are proposed in which a specific domain information nay be efficiently constructed and serviced. This paper proposes Relationship Grouping of Fuzzy Filtering Objects for Multimedia Statistic Post-office Box Construction. The proposed method exploits RelCRO( $D_{omain}$, Gi), RelSRO( $D_{omain}$, Gi) and FAS in order to group using (equation omitted)-cut. To know how well the proposed method is able to work, this paper have test against the methods with 1600 items of multimedia type information, and our system are compared with Random-Key, OGM and the proposed method. The results shows that the proposed method provides the better performance than the other methods.

Forecasting daily box-office performance is critical for planning the distribution of marketing resources, and by extension, maximizing profits. For certain movies, the number of viewers increases rapidly at the beginning of their theatrical run, and the increments slow down later. Other movies are not popular in the beginning, but the audience sizes grow rapidly afterward. Thus, the audience attendance of movies grow in different trajectories, which are influenced by various factors including marketing budget, distributors, directors, actors, and word of mouth. In this paper, we propose a method for predicting the daily performance trajectory of running movies based on the hierarchical linear model. More specifically, we focus on the effect of online word of mouth on the shape of the growth curves. We fitted the mean trajectory of the cumulative audience size as a cubic function of time, and allowed the intercept and slope to vary movie-to-movie. Moreover, we fitted the linear slope with a function of online word of mouth predictors to help determine the shape of the trajectories. Finally, we provide performance predictions for individual movies.

According to the current increase of the usefulness of information by Internet and Communication network, several methods are proposed in which multimedia information may be efficiently managed and serviced. This paper proposes FBOM(Fuzzy-Based Object Manager) using $\alpha$-cut in Object manager for Fuzzy-Based Multimedia Post-Office Box construction. The proposed system utilizes object discrimination, fuzzy filtering, and class generation structure in order to manage object using Fuzzy filtering. To know how well the proposed system are able to work, this paper have tested against the methods with 1000 items of multimedia information, and our system are compared with Random-key method and FBOM method.

Purpose - The volume and valence of online word-of-mouth(eWOM) have become an important part of the retailer's market success for a wide range of products. This study aims to investigate how the growth of eWOM has generated the product's final financial outcomes in the introductory period influences. Research design, data, and methodology - This study uses weekly box office performance for 117 movies released in the South Korea from July 2015 to June 2016 using Korean Film Council(KOFIC) database. 292,371 posted online review messages were collected from NAVER movie review bulletin board. Using regression analysis, we test whether eWOM incurred during the opening week is valuable to explain the last of box office performance. Three major eWOM metrics were considered after controlling for the major distributional factors. Results - Results support that major eWOM variables play a significant role in box-office outcome prediction. Especially, the growth rate of the positive eWOM volume has a significant effect on the growth potential in sales. Conclusions - The findings highlight that the speed of eWOM growth has an informational value to understand the market reaction to a new product beyond valence and volume. Movie distributors need to take positive online eWOM growth into account to make optimal screen allocation decisions after release.

On the 855 pure Korean commercial fictional movies, excluding diversity films, released in Korea from 2004 to August 2017, I conducted deciles distribution analysis of box office performance of those movies and average box office performance of directors, producers and lead actors who involved in making them. Deciles distribution analysis of average box office performance might be helpful to predict their next box office performance of newly produced Korean movies and to evaluate their contribution to box office performance. In baseball, the various index such as winning rate, on-base percentage, slugging percentage, stolen base percentage, battling average, earned run average is used for predicting and reviewing of professional players. In this study, I evaluate the script's narrative quality by the indirect method of insight and judgment of creative manpower involved in making the movies. For the more productive prediction, direct statistical analysis method on the narrative of the script needs to develop. Time series analysis is required to evaluate the rise and fall of creative manpower and network analysis is also necessary to see the interaction among creative people.

Korea film market is heterogeneously divided market that comes from competition between Korean movies and foreign imported movies. This research empirically analyzes genre differentiation in Korean film market with three dimensions (film audience preference, production and import, box office hit). The results indicate that, first, audiences who preferring Korean movie preferred 'cultural factor oriented genres', but audiences who preferring foreign movie preferred 'high budget oriented genres'. Second, imported foreign movie genre distribution was little bit different with box office hit genre of foreign movies. Foreign movie was imported not only hit genre (action genre) but also low cost genre (comedy and Drama/melodrama genre), but most of all Korean film was produced in box office hit genres (comedy and Drama/melodrama genre), third, Korean movies hit a box office in comedy and Drama/melodrama genre, but foreign movies hit a box office in action and SF/Fantasy genre. Those results show that Korea movies' genres are concentrated very much in cultural factor oriented genre. Those results can give implication of diversity policy and movie production strategy of Korea film market.

The purpose of this study is to find the factors of the box office record in Korean popular music. For this purpose, 1.239 musics were selected in the Gaon digital weekly album chart from second week July 2013 to first week July 2014. The result can be summarized as follows: First, entertainment of music company, distribution of music company, singer, OST(Original Sound Track), television show, SNS and high ranking in the first week of its release are the factors of the box office record in Korean popular music. Second, entertainment of a large number of music production company is more effective than the others, but there is no difference in the case of distribution music company. Third, musics of singers who have large number of music ranked Gaon digital chart and appearance of television show program are effective in the box office record in Korean popular music. Fourth, SNS are great factors to promote Korean popular music. Fifth, it is important to rank high position in the first week of its release.

In the early years of the Koryo dynasty(877~1392), the grain production was encouraged and the consumption of meat was abstained because of the Buddhism. Therefore, desserts including rice cos and cookies and teas were prevalent. Specially, the cooking skill of the desserts was highly developed because the desserts were the requisite of offered in Buddhist service and national ceremonies. Also, the king took the lead in abstaining to eat meat. According to $\boxDr$Koryodokyung$\boxUl$ , People in the early Years of the Koryo dynasty were unskilled to slaughter for serving meat to the envoy from China. Most ceremonies in Koryo dynasty were held fur retainers by king and the ceremonies held to celebrate the coronation, birth of the royal grandchildren, and royal birthday, and to treat the envoys and merchants from China(Song dynasty) and Tamra kingdom. The ceremonies were continuously held from the early year to the later year of Koryo dynasty. The aristocracy of the Koryo dynasty often held the extravagant ceremonies and drank liquor a lot in the ceremony and offered the extravagant foods such as oil-and-honey pastry and milk, which caused the national problem later. The royal religious ceremonies held often in the Koryo dynasty were ancestor worship ceremony, tea ceremony, lotus lantern ceremony, Palgwanhoe, etc. In Koryo dynasty, there were several government offices that took charge of royal dietary culture as follows: 1. Yomulgo (料物庫) - government office supplied with provisions 2. Sasunseo(司謄署) - government office that took charge of various kinds of side dishes 3. Saonseo(司酪署) - government office that took charge of wine and liquor 4. Naejangtaek(內莊宅) - government office managed paddy fields and dry fields owned by royal family 5. Sangsikguk(尙食局) - government office same as Sasunseo that took charge of various kinds of side dishes, the name changed to Sasunseo later 6. Sungwanseo (謄官署) - government office that took charge of foods for various religious services and ceremonies 7. Naewonseo (內園署) - government office that took charge of the garden
