Nowadays, online word-of-mouth has become a powerful influencer to marketing and sales in business. Opinion mining and sentiment analysis is frequently adopted at market research and business analytics field for analyzing word-of-mouth content. However, there still remain several challengeable areas for 1) sentiment analysis aiming for Korean word-of-mouth content in film market, 2) availability of machine learning models only using linguistic features, 3) effect of the size of the feature set. This study took a sample of 10,000 movie reviews which had posted extremely negative/positive rating in a movie portal site, and conducted sentiment analysis with four machine learning algorithms: naïve Bayesian, decision tree, neural network, and support vector machines. We found neural network and support vector machine produced better accuracy than naïve Bayesian and decision tree on every size of the feature set. Besides, the performance of them was boosting with increasing of the feature set size.

This study developed a model for predicting the number of VOD uses of IPTV, an online market in the film industry. A machine learning-based prediction model was established using the VOD usage data collected by the Korean Film Council from 2017 to 2021. Through literature research and cluster analysis, the difference between the offline market and the online market is revealed, and a new category of VOD usage is proposed. The purpose is to help IPTV companies establish marketing strategies as well as support decision-making by developing a machine learning-based VOD usage prediction model.

This paper suggests a method for predicting a box-office success of the film. Lately, as the growth of the film industry, a variety of studies for the prediction of market demand is being performed. The product life cycle of film is relatively short cultural goods. Therefore, in order to produce stable profits, marketing costs before opening as well as the number of screen after opening need a plan. To fulfill this plan, the demand for the product and the calculation of economic profit scale should be preceded. The cases of existing researches, as a variable for predicting, primarily use the factors of competition of the market or the properties of the film. However, the proportion of the potential audiences who purchase the goods is relatively insufficient. Therefore, in this paper, in order to consider people's perception of a movie, Twitter was utilized as one of the survey samples. The existing variables and the information extracted from Twitter are defined as off-line and on-line element, and applied those two elements in machine learning by combining. Through the experiment, the proposed predictive techniques are validated, and the results of the experiment predicted the chance of successful film with about 95% of accuracy.

Many festivals are based on overseas municipalities 'city image marketing' planning. This trend is gradually reflected in this country as with the Kimcheon International Family Theatre Festival in the Republic of Korea. Gimcheon promotes itself as the central city of happiness 'city image marketing'. Most of these dimensions are in the middle of planning a festival when the Manjiman Kimcheon International Family Theatre Festival Theatre Festival, and the differentiation of the other audiences that drive successful practices in terms of box office need to be determined. This paper presents the history and status of the Kimcheon International Family Theatre Festival Theatre Festival and others based on the reports point out the distinction of a 100% share of the audience for the fifth consecutive year to analyze the cause. In particular, with local art and local performing arts festivals, audiences through a combination of 'show' Theatre Festival are also indirectly involved in the 'touch and feel' willingness to participate. In the Kimcheon International Family Theatre Festival there are significant challenges for improvements in significance.

This article analyzes film performances in the Korean movie market utilizing three-stage models that incorporate available information in three different stages of the movie life cycle, i.e., at the time of its release, at the end of the first week, and at the end of its life cycle. Based on the premise that the performance of a movie is affected principally by factors of scale, evaluation, and competition, we attempted to ascertain the effects on these factors on performances, and how they differ in different stages. Also, by analyzing domestic and foreign movies released in Korea separately, we were able to compare the different effects of the three factors on the performances of the two categories of movies. Additionally, our movie performance models incorporated herding behavior among the customers. Our results demonstrate that herding is prominently observed after the first week only for domestic movies. In general, the scale factor has been shown to be most important for movie performances in all stages. For foreign films, it is particularly critical for the first week and total performances. Whereas the evaluation factor influences domestic film performance more strongly at the screen choice stage, it affects the performance of foreign films more strongly in the later stages of the life cycle. As compared to foreign films, domestic film performance appears to be more sensitive to the competition factor. We also discuss the effects of covariates such as genre and symbolicity on movie performance.

Microbiological and organoleptic qualities of boiled anchovies were evaluated during storage for 8 months at different temperatures and packaging methods. Microbial populations of marketing samples were 106~107 CFU/g in aerobic bacteria, 103~106 CFU/g in yeasts/molds and 103~105 CFU/g in coliforms, respectively, which were the highest in retail sample, followed by in military goods and wholesale sample. Moreover, anchovies supplied for retail sale and military goods were contaminated with sanitary indicative microbes. The samples stored at ambient condition(15~33$^{\circ}C$, RH 5$0^{\circ}C$95%) lost their marketable quaity mainly due to microbial propagation prior to 6 months, irrespective of packaging methods, corrugated-cardboard box and laminated-film(nylon 15${\mu}{\textrm}{m}$/PE 100${\mu}{\textrm}{m}$). However, cooling(5~1$0^{\circ}C$) as well as well as freezing temperatures($\leq$-18$^{\circ}C$) following laminated-film packaging were effective for keeping the organoleptic qualities of stored anchovies up to 8 months. The population of yeasts and molds was shown the quality-indicative criteria for stored anchovies and their critical levels were 5.00 log counts/g, showing a higher negative-correlationship(r=-0.901) with changes in organoleptic quality.

This study takes a close look at the recent success of independent documentaries to find its implications and a way to invigorate Korean documentary ecosystems. To this aim, this study performed in-depth interviews with independent documentary film makers and television documentary directors. Also, it analyzed the case of POV (Point Of View), which is television's longest-running showcase for independent documentary films in the USA. The results display that independent documentaries convey competitive edge of contents and expansion of distribution and funding through film industry systems, based on the producer systems, global distribution networks of overseas pitching and film festivals, marketing and audience strategy of film industry. Although this shows its molding of documentary industry ecosystems, there are great needs for various platforms other than film industrial outlet in order to make an advancement of the ecosystems under the digital environment. POV works on the basis of 'open sourcing' form when collaborating with independent film makers. Independent documentaries picked up by POV are aired on PBS, streamed via its online service, and distributed through community screenings; this three-outlet strategy makes POV a unique platform and has a relevance and feasibility to apply for Korean documentary ecosystems. Therefore, this study suggests to create a platform adopting POV system hoping that more studies and efforts would come for various and novel platform building so to make more advanced and invigorated ecosystems of Korean documentary.

This study was conducted to find the potential of polyethylene wrapping, ethylene scrubber, and Prolong as postharvest application in oriental pear, 'Niitaka'. Polyethylene film($30{\mu}m$) wrapping greatly reduced weight loss during storage for 80 to 110 days but the occurrence of dark skin browning became severe because of high humidity in polyethylene bags. Also, in long term storage of 110 days, parts of fruit developed uneven skin disorder or rupturing of cuticle layer. Ethylene scrubber reduced uneven skin disorder but no beneficial effect was found on the prevention of core breakdown. This indicates that the ethylene scrubber probably be effective when applied dicrectly to the storage room. The immediate application of Prolong to harverted fruit was confirmed not to be useful as postharvest treatment in 'Niitaka' pears.
