In order to establish an effective management strategy for invasive species early detection and regular monitoring are required to assess their introduction or dispersal. Environmental DNA (eDNA) is actively applied to evaluate the fauna including the presence of invasive species as it has high detection sensitivity and can detect multiple species simultaneously. In Korea, the applicability evaluation of metabarcoding is being conducted mainly on fish, and research on other taxa is insufficient. Therefore, this study identified the feasibility of detecting invasive species in Korea using eDNA metabarcoding. In addition, to confirm the possibility of detection by taxa, the detection of target species was evaluated using four universal primers (MiFish, MiMammal, Mibird, Amp16S) designed for fish, mammals, birds, and amphibians. As a result, target species (Trachemys scripta, 3 sites; Cervus nippon, 3 sites; Micropterus salmoides, 7 sites; Rana catesbeiana, 4 sites) were detected in 17 of the total 55 sites. Even in the selection of dense sampling sites within the study area, there was a difference in the detection result by reflecting the ecological characteristics of the target species. A comparison of community structures (species richness, abundance and diversity) based on the presence of invasive species focused on M.salmoides and T.scripta, showed higher diversity at the point where invasive species were detected. Also, 1 to 4 more species were detected and abundance was also up to 1.7 times higher. The results of invasive species detection through metabarcoding and the comparison of community structures indicate that the accumulation of large amounts of monitoring data through eDNA can be efficiently utilized for multidimensional ecosystem evaluation. In addition, it suggested that eDNA can be used as major data for evaluation and prediction, such as tracking biological changes caused by artificial and natural factors and environmental impact assessment.

This paper aims to examine to the political unconsciousness of social movies that have caused social repercussions in the 2010s, and to study the social imagination of Korean films at that time. Korean Movies such as (2013), <1987>(2017) and (2017) reflect the ethos of civil society based on common sense and justice. The epic structure was the same as that of ordinary citizens, who move toward a public space (court, square) after awakening their political correctness. More than anything else, the fact that such films were based on "a historical fact" could have been a strategy to avoid censorship in the era of the blacklist. In these social films, courts and squares have become places for democracy. The conservative government of the time was tired of anti-government resistance and the politics of the square. Thus, films from directors and producers blacklisted were difficult to produce. That's why the court in the movie during this period could become a symbolic proxy for the "legitimate" reenactment of the politics of the square, which was subject to censorship and avoidance by the regime of the time. Meanwhile, the square has gradually become the main venue for political films that advocate "historic true stories." The square of the 1980s, which appeared in the movies, will be connected to the Gwanghwamun candlelight square that audiences experienced in 2017. Furthermore, it was able to reach the concept of an abstract square as an "open space for democracy." At the foundation of these works is a psychological framework that equates the trauma of the failed democratic movement of the 1980s to the trauma of the failed progressive movement of the 2010s. Through this study, we were able to see that social political films in the 2010s were quite successful, emphasizing "political correctness" and constitutional common sense. But they also had limitations as "de-political popular films" that failed to show imagination beyond the censorship of the blacklist era.

Through the expansion of platforms in the media era, this paper notes the phenomenon in which 'high-teen romance drama,' a genre which had been marginalized in the past, began to re-emerge. It analyzes the 'high-teen romance drama,' which is moving from TV to the Web and being produced in various ways, while successfully returning to the TV drama format. This study sums up the latest trends in TV and web-based high-teen romance dramas, and as a case study, this paper examines the characteristics of the 'high-teen romance drama' in relation to the platform's environment through the web drama A-Teen, TV drama 18 Moment. Due to the restriction of ratings, high-teen romance dramas have been one of the largely marginalized genres on television. But in the web space, high-teen romance dramas are no longer non-mainstream. The high-teen romance drama has been solidifying its position through the Web, with absolute support from young viewers. Web dramas are gradually expanding their influence on the genre and subject of TV dramas. The high-teen romance drama is one of the most prominent examples of this trend. The popular interest and success of the high-teen romance web drama has brought the forgotten high-teen romance drama back to TV. The web drama A-Teen is a high-teen romance drama about everyday life and love of high school students, and became one of the most popular and popular web dramas, leading to a Season 2. A-Teen actively utilizes teenage culture and expression, and a strategy that leads to empathy among teenage viewers. In A-Teen, love is recreated in a way that relieves the depth of overconsumption emotions. Instead of dealing in depth with the inner conflict over love, it takes an approach ofpresenting the emotional change of love in real time and forming a consensus with the acceptor. The TV drama 18 Moment is one of the programs that has helped refocus attention to TV-hitting romance dramas. 18 Moment underlines the growth of the characters, with the main characters reaching maturity through love as fresh and innocent teenagers. The TV drama 18 Moment is a high-teen romance drama that has been transformed into a way to apply the web-fadding high-times grammar while retaining the typicality of existing TV hagwons to suit the TV broadcasting environment. As the Internet becomes more ubiquitous, video content is changing based on the newly emerging platforms. Dramas no longer mean just traditional television media. While considering the limitations of TV, this paper analyzed the background of the rebirth of the high-teen romance drama, which had been marginalized, through the web platform. This is meaningful in that it identifies and considers the increasing popularity of this genre of drama.

The purpose of this work is to analyze the case that Yeongju Municipality Government of Gyeongbuk and Jung Donuts Co., Ltd., a franchise company, activated local economy through Farm's Franchise Commercialization (FCC) and to establish the concept of FCC. As a food service franchise company, Jung Donuts specializes in making and selling glutinous rice donuts. In cooperation with Commodity Dept. of Yeongju Municipality Government, the company cultivates raw materials under contract. Such farm's franchise business has the following advantages: First, it is meaningful in the point that it contributes to opening a new market of local agricultural products in a stable way. In short, by using most agricultural products of Yeongju as raw materials, the business serves as a stable market for farmers. Secondly, it is possible to set a reasonable price through stable supply of raw materials. It is to advantages of both producers and consumers. Thirdly, the business brings about the effect of employment rise. It can cause increases in employment of franchise head office and its agencies, and of the Commodity Dept.. Lastly, it produces the promotion effect of local special products. By expanding its agencies across the country, a franchise business can promote the items of raw materials in terms of marketing. The successful FCC needs to meet three requirements as follows. The first one is to establish systematic logistic system. Stable logistic system is required in order to directly distribute and deliver products to nationwide agencies by a producing place. The second one is constant R&D activity. Through the activity of R&D of raw materials and equipment, they should be used most effectively. The third one is to build mutual trust relationship. For long-term business achievements, it is required to establish mutual trust relationship in which relevant entities share their visions with each other and cooperate with each other.

This essay is focused on finding women's voice in oral narratives of social memory of national violence and resistance. The books of oral narratives of women who had experienced the national violence and participated in the resistance through historic events such as 5.18, have been published recently. This study is based on the materials that have interviewed women experienced the historic event '5.18' in Gwangju. In this study, there are analyses of the materials of the memory of violence and resistance of '5.18', which have contained the texts written by intellectual males and the oral narratives of females directly involved. So far, the memory and experience of women have not been presented in its entirety in the field of social discourse of '5.18'. In the field women's words were translated in men's words, so the real words disappeared and in the end remained unspoken words. And besides, the existence of women are substituted with the limited images (for example women's body destroyed) presented by men's words in memorial materials. In narratives of '5.18', women are reduced to the images of bodies destroyed by national violence. The destroyed bodies are places for exhibition and disclosure of national violence. Women are not presented as the subjects of the social resistance in oral or written narratives of '5.18'. The images of females are only vehicles to urge the male subjects to resist against unjust violence. In this context, men are interpreted for the protectors of sisters, daughters, wives. Since 1980s, the symbol of '5.18 Gwangju' has represented the most ideal community in Korean society. But women have been on the borderline or outside of the community in fact. However, women intend to construct themselves as the subjects of resistance through the spoken words. They have tried to make the politic places for themselves in the social field by speaking and speaking constantly. The desire to speak out is becoming stronger for women, so these days more words are spoken by more women and more oral narratives made by women are revealed in social discoursive field. So the place for women's voice is expanding in social memorial field of '5.18'.

Constructing attractive bundle offers depends on more than an understanding of the distribution of consumer preferences. Consumers are also sensitive to the framing of price information in a bundle offer. In classical economic theory, consumers' utility should not change as long as the total price paid stays same. However, even when total prices are identical, consumers' preferences toward a bundle product could be different depending on the format of price presentation and the locus of price discount. A weighted additive model predicts that the impact of a price discount on the overall evaluation of the bundle will be greater when the discount is assigned to the more important product in the bundle(Yadav 1995). Meanwhile, a reference dependent model asserts that it is better to assign a price discount to a tie-in component that has a negative valuation at its current offer price than to a focal product that has a positive valuation at its current offer price(Janiszewski and Cunha 2004). This paper has expanded previous research regarding price discount presentation format, investigating the reasons for mixed results of prior research and presenting new mechanisms for price discount framing effect. Prior research has hypothesized that bundling is used to sell a tie-in component with an offer price above the consumer's reference price plus a focal product of the same offer price with reference price(e.g., Janiszewski and Cunha 2004). However, this study suggests that bundling strategy can be used for increasing product's attractiveness through the synergy between components even when offer prices of bundle components are the same with reference prices. In this context, this study employed various realistic bundle sets with same price between offer price and reference price in the experiment. Hamilton and Srivastava(2008) demonstrated that when evaluating different partitions of the same total price, consumers prefer partitions in which the price of the high-benefit component is higher. This study determined that their mechanism can be applied to price discount presentation formats. This study hypothesized that price discount framing effect depends not on the negative perception of tie-in component with offer price above reference price but rather on the consumers' perceived consumption benefit in bundle product. This research also hypothesized that preference for low-benefit discount mechanism is that perceived consumption benefit reduces price sensitivity. Furthermore, this study investigated how consumers' concern for quality in a price discount--a factor not considered in previous research--influences price discount framing. Yadav(1995)'s experiment used only one magazine bundle of relatively low quality uncertainty and could not show the influence of perceived uncertainty of quality. This study assumed that as perceived uncertainty of quality increases, the price sensitivity mechanism for assigning the discount to low-benefit will increase. Further, this research investigated the moderating effect of uncertainty of quality in price discount framing. The results of the experiment showed that when evaluating different partitions of the same total price and the same amount of discounts, the partition that discounts in the price of low benefit component is preferred to the partition that decreases the price of high benefit component. This implies that price discount framing effect depends on the perceived consumption benefit. The results also demonstrated that consumers are more price sensitive to low benefit component and less price sensitive to high benefit component. Furthermore, the results showed that the influence of price discount presentation format on the evaluation of bundle product varies with the perceived uncertainty of quality in high consumption benefit. As perceived uncertainty of quality gradually increases, the preference for discounts in the price of low consumption benefit decreases. Besides, the results demonstrate that as perceived uncertainty of quality gradually increases, the effect of price sensitivity in consumption benefit also increases. This paper integrated prior research by using a new mechanism of perceived consumption benefit and moderating effect of perceived quality uncertainty, thus providing a clearer explanation for price discount framing effect.

Researchers in channel dyads have devoted much attention to relationship between interdependence (i.e. interdependence enymmetry and total interdependence) and conflict that promote channel performance. In social science, in spite of the inconsistent results in marketing practice, there are two contradictory theories explain the relationship between interdependence and conflict - bilateral deterrence theory and conflict spiral theory. The authors apply these theories to co-marketing alliance situation in terms that this relationship is also incorporated both company's dependence, either from one company's perspective or each partner about its respective dependence. Using survey data and archival data from 181 companies enlisted in a telecommunication membership program, the authors find out the relationship between interdependence and conflict as well as investigate the antecedents of interdependence - transaction age, transaction frequency, the numbers of alliance partner, and co-marketing alliance specific assets according to previous researches. Using PLS analysis, the authors demonstrate that, with increasing total interdependence in a telecommunication membership program, two co-marketing partners' conflict level is increased in accord with the author's conflict spiral theory predictions. As expected, higher interdependence asymmetry has negative value to level of conflict even though this result is not statistically significant. Other findings can be summarized as follows. In the perspective of telecommunication company, transaction age, transaction frequency, and co-marketing alliance specific assets have influence on its dependence on a partner as independent variables. To the contrary, in a partner's perspective, transaction frequency, co-marketing alliance specific assets and the numbers of alliance partner have significantly impact on its dependence on a telecommunication company. In direct effect analysis, it is shown that transaction age, frequency and co-marketing alliance specific assets have direct influence on conflict. This results suggest that it is more useful for a telecommunication company to select a co-marketing partner which is frequently used by customers and earned high rates of mileage. In addition, the results show that dependence of a telecommunication company on a co-marketing partner is more significantly effected to co-marketing alliance conflict than partner's one. It provide an effective conflict management strategy to a telecommunication company for controling customer's usage rate or having the co-marketing partner deposit high level of alliance specific investment (i.e. mileage). To a co-marketing partner of telecommunication company, it is required control the percentage of co-marketing sales in total sales revenue or seek various co-marketing partners in order for co-marketing conflict management. The research implications, limitation and future research of these results are discussed.

Research on investment determinants of accelerators, which are attracting attention by greatly improving the survival rate of startups by providing professional incubation and investment to startups at the same time, is gradually expanding. However, previous studies do not have a theoretical basis in developing investment determinants in the early stages, and they use factors of angel investors or venture capital, which are similar investors, and are still in the stage of analyzing importance and priority through empirical research. Therefore, this study verified for the first time in Korea the discrimination and effectiveness of investment determinants using accelerator investment determinants developed based on the business model innovation framework in previous studies. To this end, we first set the criteria for success and failure of startup investment based on scale-up theory and conducted a survey of 22 investment experts from 14 accelerators in Korea, and secured valid data on a total of 97 startups, including 52 successful scale-up startups and 45 failed scale-up startups, were obtained and an independent sample t-test was conducted to verify the mean difference between these two groups by accelerator investment determinants. As a result of the analysis, it was confirmed that the investment determinants of accelerators based on business model innovation framework have considerable discrimination in finding successful startups and making investment decisions. In addition, as a result of analyzing manufacturing-related startups and service-related startups considering the characteristics of innovation by industry, manufacturing-related startups differed in business model, strategy, and dynamic capability factors, while service-related startups differed in dynamic capabilities. This study has great academic implications in that it verified the practical effectiveness of accelerator investment determinants derived based on business model innovation framework for the first time in Korea, and it has high practical value in that it can make effective investments by providing theoretical grounds and detailed information for investment decisions.

Recently, the alternative meat (food) market is growing rapidly due to the increase in meat consumption due to global population growth and income improvement, as well as issues such as equal welfare, carbon neutrality, and sustainability. The government is also developing a green bio convergence new industry development plan to foster alternative foods, but there are difficulties in commercialization due to the lack of technology and insufficient production facilities among domestic small and medium-sized enterprises, so it is necessary to build joint utilization facilities and equipment to resolve the difficulties faced by companies. am. In addition, small and medium-sized enterprises are having difficulty developing and commercializing plant-based meat substitutes due to a lack of technical skills, and related equipment is expensive, making it difficult to build equipment on their own. Accordingly, Jeollabuk-do is pursuing a strategy to secure the source technology for development, processing, and industrialization of plant-based substitute meat at the level of developed countries by establishing a plant-based alternative meat industrialization center. In this study, an economic feasibility analysis study was conducted when a plant-based alternative meat industrialization center is built in Jeollabuk-do. As a result of the analysis, B/C=1.32, NPV=374 million won, and IRR=4.8%, showing that there is economic feasibility in establishing an alternative meat industrialization center. In addition, as a result of analyzing the regional economic ripple effect resulting from the establishment of an industrialization center, if 38 billion won is invested in Jeollabuk-do, the nationwide production inducement effect is 74 billion won, the added value inducement effect is 29.8 billion won, and the employment inducement effect is 672 people

A smart phone has been widely spread around world and makes people enjoy online shopping in any time and any place. Recently it also changes the distribution environment. O2O (Online-to-Offline) service becomes new normal due to its convenience of ease shopping of product and services. O2O service market shows steady and steep growth, It is reported that, however, 80% of the businesses has been discontinued within the first year because of unstable business models, customer dissatisfaction and distrust of service. Therefore, it is very important research issue to find out influential factors promoting continuous usage intention of O2O service. Previous study shows that it only considers online characteristics and lack of analysis about offline characteristics and social impact factors. The purpose of this paper is to find out continuous usage intention factors of O2O services by literature review, case analysis, and empirical test. A comprehensive research model and related hypothesis are developed and tested by using a structural equation, Survey was carried out among users who have used O2O service including payment service for at least once. Finally 611 samples are selected out of total 813 surveys. The result shows that the model is theoretically proved and 12 out of 17 hypotheses are accepted. The contribution of this paper is that it provides a new theoretical research model about continuous usage intention factors as well as practical guidelines about promoting continuous usage and growth strategies of O2O service.
