Using the inter-industry tables over the period 2010-2013 published by the Bank of Korea, this paper attempts to uncover the national economic role of the marine environmental industries through the estimation of their market size and value-added, and to analyze their economic effects through inter-industry analysis. The results show that the market size of the marine environmental industries has increased from 1.34 trillion won in 2010 to 1.97 trillion won in 2013 and their share in total national output went up from 0.04 % in 2010 to 0.05 % in 2013. Moreover, the value-added of the marine environmental industries, 618.5 billion won in 2010, amounted to 841.5 billion won in 2013 and their proportion in total national value-added has grown from 0.05 % in 2010 to 0.06 % in 2013. Three findings emerge to be used demand-driven model from the inter-industry analysis. First, the production-inducing effect of 1.0 won production or investment in the marine environmental industries has decreased from 1.8845 won in 2010 to 1.8115 won in 2013. Second, the value-added creation effect of that has declined from 0.7680 won in 2010 to 0.7063 in 2013. Third, the employment-inducing effect of 1.0 billion won production or investment in the marine environmental industries has went down from 10.17 people in 2010 to 9.18 people in 2013. In short, the market size and value-added of the marine environmental industries show an increasing trend, but their economic effects reveal a diminishing trend.

The globalized modern society has facilitated the borderless travel which always starts and ends at the airport. The airport now serves the gateway in spreading and delivering the culture, beyond the role of simply providing assistance to the transport means. Nowaday, the nations throughout the world expand the existing facilities or build the new airport competitively as the medium to link the travel and modern community as well as the symbolism of economic and technical improvement and it has been developed as a huge industry creating a high added value, beyond the simple transport services. Incheon International Airport has already been recognized as the world-class airport but still has a long way to go. It's necessary to develop the comprehensive cultural and art concept for sustainable value creation, instead of remaining as the airport with sophisticated facilities alone.

Network externality can be defined as the effect that one user of a good or service has on the value of that product to other people. When a network externality is present, the value of a product or service is dependent on the number of others using it. There exist asymmetries in network externalities between the online and traditional offline marketing channels. Technological capabilities such as interactivity and real-time communications enable the creation of virtual communities. These user communities generate significant direct as well as indirect network externalities by creating added value through user ratings, reviews and feedback, which contributes to eliminate consumers' concern for buying products without the experience of 'touch and feel'. The offline channel offers much less scope for such community building, and consequently, almost no possibility for the creation of network externality. In this study, we analyze the effect of network externality on the competition between online and conventional offline marketing channels using game theory. To do this, we first set up a two-period game model to represent the competition between online and offline marketing channels under network externalities. Numerical analysis of the Nash equilibrium solutions of the game showed that the pricing strategies of online and offline channels heavily depend not only on the strength of network externality but on the relative efficiency of online channel. When the relative efficiency of online channel is high, the online channel can greatly benefit by the network externality. On the other hand, if the relative efficiency of online channel is low, the online channel may not benefit at all by the network externality.

The ocean is a unique space for exchange with the city, forming an organic relationship between people and waterfront areas. The marine healing industry improves quality of life through medical care and well-being, and creates added value by combining with the medical industry. The policy analysis results are as follows. First, the marine healing industry is the newest high-growth area. Furthermore, a professional medical service hospital is the first priority. This will include the development of marine healing facilities and strengthening forest healing connectivity, emphasizing the development of highly specialized medical technologies. The second priority is value creation in marine healing specialization, accompanied by an integrated and systematic policy for research and development of new medicines in marine healing effects. It is also important to apply new market trends and develop applied marine healing service programs. Thirdly, it is necessary to explore the possibility of a fragmented market for policy development.

In this paper, we analyze the economic ripple effects of technology related to the unmanned aerial vehicle industry by applying industry association analysis. Specifically, the effects of employment creation, value added inducement, sensitivity coefficient, and influence coefficient can be calculated, and implications for the analysis result are presented. As a result, the employment inducement effect was confirmed to be 10.017 persons per 1 billion won of investment. The value added inducement effect was much higher than the other manufacturing industry average (employment inducement coefficient: 2.285, value added inducement coefficient: 0.581) when the 1 won budget was added, resulting in 0.9771 won added value. In the unmanned aerial vehicle industry, the coefficient of sensitivity, which means the front chain effect, is 0.7870, which is lower than the manufacturing average (sensitivity coefficient 1.125), and the coefficient of influence, which means the backward chain effect, is 1.161, which is higher than the manufacturing average (influence coefficient: 1.116). Therefore, it is classified as the final demand manufacturing industry. This means that the unmanned aerial vehicle industry is an industry that is less affected by economic fluctuations and can be interpreted as an industry with a greater economic impact than other sectors. Based on these data, it can be used to establish the R&D investment direction policy of the unmanned aerospace industry.

With the e-business paradigm emerging, the website became a critical resource for most corporations. However, the amount of value creation through internet is still in question. This paper shows the result of an exploratory study on website assessment, following the tradition of Technology Acceptance Model (TAM). We viewed the intended usage as the value of the website and added such factors as playfulness, commitment, system quality, and information security as external variables of the model. Website types, visiting purposes, and the user system quality were included as moderators. The website value could differ depending on website types, purposes of the use and system quality. In the case of internet shopping malls, playfulness, compatibility, website quality were identified as key influencers, while for stock trading users, however, commitment and security factors are more important. In terms of user purposes, information search requires both the compatibility and the website quality. Also the website quality was strongly affected by the user system quality. In other words, any investment of upgrading the website system quality can be meaningless unless the user system quality is improved as well. For each variable considered, empirical results are discussed and practical implications are provided.

Having set a trend for luxury fashion brand markets since the $17^{th}$ century, France has established the norms and the forms of the fashion business. In addition, it has maintained its status as a leading fashion power by discovering economic value from the intangible value of design and brand, and developing fashion into a high value-added industry. This paper aims to examine the socio-cultural factors that have exerted a positive influence on the formation of "fashion power" in France from a historical perspective. It will focus on four major external historical factors that made France the top fashion power: insights and innovation of French leaders as well as their constant concerns and efforts for the promotion of fashion, a tradition of experimental cultures and arts, open and the public-centered social environment and an atmosphere of cherishing the values of creation, and the establishment of a legitimate system that protects them.
