The effect of storage temperatures ($0^{\circ}C$and $20^{\circ}C$) and packing functional film for fruit quality were examined in 'Fuyu' persimmon. The fresh weight loss was delay more effectively by the inhibition of transpiration when functional film was used. The firmness was effectively maintained in functional film packages at low temperature ($0^{\circ}C$), which might result from the beneficial combination of $CO_2$ and $O_2$. The soluble solid contents was higher with packing of functional film at $0^{\circ}C$ than at room temperature ($20^{\circ}C$). Highest $CO_2$ production in functional film bags was observed in room temperature storage after one week and thereafter declined sharply whereas lowest in 8 weeks. $CO_2$ concentration regardless of packing slowly increased to $5.2{\mu}L{\sim}10.2mL{\cdot}kg^{-1}{\cdot}h^{-1}$ until 8 weeks of low temperature due to persimmon respiration. Hunter 'b' value changed greatly yellowness according to temperature of storage but there were no significant differences among packaging treatments. Effects of functional film and low temperature in slower softening were consistent. This results suggested that the packing functional film at low temperature resulted in the best retention of quality market.

To investigate the effects of functional MA films (FMA) masterbatched by zeolite powder treated with 1 N HCl, 0.5 N NaCl solution and anti-fogging agent (NA) compared with control on the freshness extension of 'Fuji' apples during storage at $15^{\circ}C$. Preference, weight loss, total ascorbic acid, sugar content, acidity, change of gas composition in package were measured. After 150 days of storage, the weight loss of control (L) apples was 1%, that of apple in FMA film (NA) was 1.5% after 150 days. Total ascorbic acid content of apples in control (L) after 150 days was 2.09 mg%, those of apple in FMA film (NA) was 2.72 mg%. The titratable acidity of apple in FMA film was higher than that in control, while soluble solids content of apples in FMA film was lower than that in control after 150 days. Ethylene gas adsorbability in control was 192.2 ppm and those in FMA film was 141.4 ppm after 150 days. Overall, apples in FMA film was better than that of control. It was verified that apples packed with LLDPE film (control) lasted about 130days, while those with FMA films lasted about 170 days. Also, FMA films treated with anti-fogging agent few different compare to nontreated film, but commerdity on the display in market was considered higher than that of non-treated anti-fogging agent.

The purpose of this paper is to investigate upon a diversification strategy through market creation of CJ Group, which has contributed in positioning of the firm as one of the leading conglomerates in South Korea. With such objective, the background of CJ Group, followed by its business diversification strategies were explored, with reference to several case studies. The history of CJ Group began with establishment of CheilJedang Industrial Corporation in 1953, as the first domestic sugar producer and exporter of South Korea. The corporation gradually expanded its business ever since at both national and global level, to include the fields of food production, pharmaceutical, biotechnology, and life chemicals. Later, CheilJedang (CJ) Group was established as an affiliate of CheilJedang Industrial Corporation. With such independence, extension of business has been witnessed across the industries of media, entertainment, finance, information technology and distribution. Thus, the current CJ Group pursues to define itself as a progressive global living culture company with four major business categories from food and food service, biotechnology, entertainment and media, and logistics. Despite its success in today's market, CJ Group underwent hardships in its business diversification in 1990s due to indiscreet management, along with the Asian financial crisis. Here, many firms overcame the financial difficulties by taking advantage of the exchange rate for overseas expansion. Though, CJ Group tried to differentiate itself by focusing on the domestic market by creating something out of nothing. Hence, CJ Group takes a unique position among many cases of business diversification and their categorization. In an effort to identify and classify the types of growth experienced by the top 30 companies in South Korea, the firms were categorized into four groups according to their diversification strategies adapted after the Asian financial crisis. Based on the mode and time of entry, corporations were identified either as the 'Explorer', 'Invader', 'Venture Capitalist', or 'Assimilator'. Here, the majority of the firms showed the qualities of Invader, entering mature markets through large-scaled mergers and acquisitions. However, CJ Group was the only firm that was categorized as an Explorer, for its focus on the newly emerging service sector in culture-contents industry. This diversification strategy through market creation is worth examining, due to its contribution in generating simultaneous growth between the market and the company itself. Diverse brands of CJ Group have been referred to as case studies in this regard, from 'Hatban', 'Cine de Chef', 'VIPS' to 'CJ GLS'. These four businesses, each to represent processed food, film, restaurant service, and logistics industries respectively, show CJ Group's effectiveness in creating a whole new category of goods and services that are innovative. In fact, such businesses not only contributed in advancement of consumers' wellbeing, but toward generating additional value and employment. It is true that the diversification strategy of CJ Group requires long-term capital investment with high risk, compared to the other strategies mentioned in the paper. However, this model does create high employment and additional values that are positive to both the society and the firm itself. Therefore, the paper comes to a conclusion that the diversification strategy through market creation conveys the most positive impact relative to the others.

Recently Korean film industry has continuously experienced a rapid growth and expanded its influence to foreign countries. Accordingly, there have been numerous studies in various research areas to investigate the characteristics of the industry. In this study, we applied social network analysis based on the attributes such as genres, ratings, distributors, nationalities, sizes, and profitability to divide the movies into several clusters with respect to their similarity. Results suggested that the ratings and nationality rather than the genre are the major factors to divide the motion picture market into clusters and the profitability also varies much across the clusters. Furthermore, estimation of the diffusion model showed the positive relationship between the success of a movie and the word-of-mouth effect, while the relatively unsuccessful titles exhibited a monotonic decreasing diffusion pattern with the high initial demand and the early peak time.

The significance of the image content industry, as a flagship industry of the cultural content industry, is emerging globally as a high value-added trend. Since the movie industry has diverse related industries along with a positive spillover effect from cultural and economic perspectives, it ultimately strengthens national brands as well as national competitiveness. As a national strategy cultural content industry, the movie industry in each country around the world utilizes its own diverse self-protective systems. The Korean movie industry has emerged as a 10 million-strong movie-goer market; however, in reality, it is vulnerable to high film production costs and utility. The current domestic media market demands a new paradigm through the media industry as a whole; nonetheless, it is inherently limited to past film production and distribution channels. In this study, I seek to evaluate the status quo and propose a new direction for the Korea movie industry.

This study focuses on analyzing the trend of Korean movies and the issues caused by industrialization and the alternatives. The results are as follows: first, there does not exist distinctive genre movie as most of the movie producers concentrate on thoughtless genre fusion of movie, simply hoping for box office success. Second, Giant companies that has large amounts of money and distributors tend to monopolize production, distribution, and running of movie. Consequently, the development of diversity and artistry is absolutely impeded. Third, the structure of Korean movie industry make some well-known movie stars survive the film world and staff members and actors except them face economic difficulty. The solution plans for the problems mentioned above can be drawn like this; first, genre film with distinctive features should be developed. Second, the monopolistic structure of the screen should be changed. Legal organizations are required to redesign the system of unfair Korean film industry. Third, it is suggested that quantitative expansion of special theaters of diversity film be urgently needed. Fourth, appearance fees given to popular movie stars, actors, and staff members have to be provided in a balanced way. Fifth, the way for revitalization of film production should be found through the legal examination of fund for film development.

Chinese youth films fall into the dilemma of continuous development after experiencing rapid development from 2013 to 2017. How to update the creative ideas and methods of the films, arouse the audience's interest in watching and stimulate a new aesthetic experience has become a focal point for the creators who concern about the Chinese film market. "Us and Them" is a successful youth film in 2018. Its creative practice proves that defamiliarization can provide theoretical and methodological basis for the creation of Chinese youth films. Therefore, taking the current situation of Chinese youth film as the research background, treating "Us and Them" as the research object, the defamiliarization of narrative discourse and narrative content used in the film are analyzed. First, the defamiliarization of narrative discourse composed of scenes, characters and plots makes the film "stand out" from the real world. Second, the defamiliarization of narrative content composed of metropolis adoration, self-identity and hometown affection makes the film "stand out" from the existing context. These methods of creation not only meet the needs of the contemporary, but also provide an effective reference for the creation of other youth films. Research will be needed to utilize the elements of defamiliarization through the analysis of the successful case in spite of the time change.

Based on the capabilities of smartphone cameras which have developed rapidly in recent decades, coupled with and the global market penetration rate, it will study the possibility of various international exchanges through smartphone filmmaking. This aims to achieve a civilian-oriented cultural exchange, instead of simply providing capital-oriented exchanges and film production education. The Smartphone Film Workshop was held as an auxiliary event of the Korea-Vietnam Film Festival, which ran from November 17 to 22, 2017. The three-day workshop, which took place within the festival period, drew attention for its international collaboration project between Korean film directors and Vietnamese film students. The researcher conducted practical-based research while participating as a mentor at this workshop. A step-by-step approach to the entire process of production and post-production was administered, including workshop team composition, scenario, and pre-production in Korea such as shooting equipment, schedule, completion of local works, and screening. Through an analysis of exchange cases at international workshops, we will use trial and error as ways to improve and consider the results of cultural exchanges and the effects of future expectations. Taking this empirical case study into account, we anticipate more active international exchanges through the smartphone workshops.
