As a result of the development of heavy and chemical industries during the Economic Development Plan, Korean shipbuilding industry expanded its capacity rapidly and became a strategic export industry. The 1973 Arab oil crisis and the subsequent doubling of oil prices greatly reduced world demand for tankers and the market was crashed as numberous orders for tankers were cancelled in Japan and Europe. Under these circumstances, Korean Shipping industry also experienced a decrease in overseas demand for shipbuilding. The Korean government established the 'planned shipbuilding' scheme. The primary purpose of the scheme was to develop the shipbuilding industry, to link the industry to the shipping industry and to develop both industries together. However, Japanese shipping established goals linking with macro-national economic policy, such as saving foreign currencies and freight of importing goods, also assisting reconstruction and development of shipbuilding industry. To accomplish these goals, Japanese government used several policy tools such as financial assistance, law, guidance.

As global competition for green car, that is environmentally friendly car, is getting tougher, the governments and the related industries are putting their core efforts in its diffusion. However, the green car sales are disappointing so far. To overcome the gridlock, it is necessary to develop concrete analytical framework to understand the diffusion process. Based on causal loop analysis from the previous work, we have identified main variables and relationships of them in the diffusion process and developed a stock-flow diagram and mathematical formula for the main components. The model would be applied for further quantitative simulation on the diffusion process of green car and other innovative goods as well. Also, we have suggested constructive insights for the policy makers and for the related industries. First, it is important to increase consumers' willingness to consider through marketing and word of mouth to accelerate the diffusion process. Second, in the perspective of the industry, the market share of green car should be increased at the earliest possible stage and this could be done by enhancing each components of green car attractiveness(e.g. price, driving range, social infra). Third, companies should develop a balanced investment between consumer and technology sector through a flexible financial policy. Fourth, the government continuously has the role of investing in the related R&D and social infra building. We expect the green car diffusion model and related formula from the research can provide meaningful tools to analyze the diffusion process of other new and innovative goods based on its deep researched literature review.

Recently the tourism industry has achieved rapid growth and thus stands out as a means for the improvement of international payments and the acquirement of foreign currency. In particular, the hotel and major tourist travel industries have been developed for the inducement of foreign tourists. However, the manu-facturing and sales indust\ulcornerries of tourism folklore haven't developed. The reason is that the endeavor to attract tourists has been more emphasized than the development of tourism folklore which includes chief shopping items and indust-rialization. Tourism folklore plays a great role not only as material evidence of a tourist's visit to a country or region but also as a gift and a souvenir. Also it represents the image and the degree of the industrial development of the nation, so it should be congruent with the nature and the images of the region. Nevertheless, our tourism folklore has been merely mass produced by specific companies that do not represent the region's image and nature in their products. Tourism folklore development can raise the image of Choongnam and serve as a catalyst to induce tourists. Also, it can be an avenue for com$$\mu$ity publicity and industrialization. Thus, this study has examined and analyzed original products made with textiles and metal materials whether can be developed into tourism folklore. Also this study presents the example of developed tourism folklore works in a foreign country. It tries to give the unique symbolic image of Choongnam by developing the original products with Choongnam' s own materials. However, this study has shown that the actual conditions of tourism folklore development in Choongnam are seriously inferior to other industries. The producers are limited. Moreover, the product items are coarse. Many problems are being brought up which should be improved. Hereafter, to develop Choongnam's own tourism folklore, it should be carried out with financial and political support from the government, design development by industrial circles, professional design training and marketing research by the sellers.

Since the publication of Satoshi Nakamoto's white paper on Bitcoin in 2008, blockchain is in the spotlight as one of the core technologies of the Fouth Industrial Revolution, which can be used in various industries beyond simple cryptocurrency. various researches and developments are being conducted worldwide to utilize blockchain technology, and a global blockchain consortium is formed. In addition, attempts are being made to apply to various industries such as logistics, distribution, and medical care as well as the financial sector. However, blockchain tecnology developments still do not reach the level that meets these concerns and expectations. In this paper, we presents a comprehensive overview of blockchain technology by giving its brief concepts, consensus algorithms, standardization, and security threats.

Blockchain technology has the potential to revolutionize trust models and business processes in a variety of industries. However, it is considered to be the initial stage of the system that pursues autonomy rather than efficiency, and it is necessary to monitor and inspect the distributed ledger technology from the price and introduction time as compared with the existing relational DB transaction technology. However, domestic and foreign private sectors have already been activated by applying block-chain technology in the national domain, and the block chain is devoid of doubt that it is an exaggerated technology, characterized by the invariance of the record, transparency, and autonomous execution of business rules. It has begun to be utilized in history, identity, certification and auditing in the financial industry as well as various industries. In this paper, we analyze the problems such as security weakness, insufficient regulatory environment, technical consensus and lack of common standard. In addition, the business sense and possibility of the block chain technology is expected to be the innovation of the industrial ecosystem by entering into the reality system from the concept through monitoring the actual introduction performance in the field of copyright, logistics, health care and environment.

The main objective of this study aims at analyzing the national roles of fisheries in the global economy from the constitutional view point. Globalization provides general firms and businessmen with great opportunities that allow them to be able to plan and operate their business strategies beyond the national boundaries. WTO and FTA negotiations must be important facilitators of such globalization. However, Korean primary industries like fisheries under comparative disadvantage have a high probability that there may have to be the trade-offs between the primary and the industrial sector to maximize national benefits in the process of bilateral and/or multilateral international trade deals. Since, moreover, fishermen face strong binding constraints under which they hardly carry out fishing operations standing aloof from national boarders, they have to manage fishing businesses within their own national territory, to maintain and develop fisheries culture, and to explore their own destiny for themselves. Because of such reasons, the constitution imposes upon the State the duty to support and develop fisheries and fishing villages. Considering its article and spirit associated with fisheries(i.e. article 123), it seems unnecessary at this point in time that Korean society makes debates over national consensus for supporting fisheries. The reason is because the explicit provisions of the constitution do not allow their arbitrary interpretation depending upon interests or policy situations. However, where national support to the particular sector could not meet the expected social value system, there would be a great deal of chance to invite serious societal debates over such national commitment to the fisheries. Therefore, whether using it efficiently and realizing the socially expected policy goals must be a responsibility of both fisheries administration and fishing industries.

The most useful method for financial market risk management may be Value at Risk (VaR) which estimates the maximum loss amount statistically. The VaR is used as a risk measure for one industry. Many real cases estimate VaRs for many industries or nationwide industries; consequently, it is necessary to estimate the VaR for multivariate distributions when a specific portfolio is established. In this paper, the multivariate quantile vector is proposed to estimate VaR for multivariate distribution, and the Vector at Risk for multivariate space is defined based on the quantile vector. When a weight vector for a specific portfolio is given, one point among Vector at Risk could be found as the best VaR which is called as an alternative VaR. The alternative VaR proposed in this work is compared with the VaR of Morgan with bivariate and trivariate examples; in addition, some properties of the alternative VaR are also explored.

Applying the dynamic shift-share analysis, this paper decomposes inflow of foreign direct investment (FDI) of Korea for the period of 2003-2012 into three components: world growth effect, industry-mix effect and competitive effect. Taking the group of developed countries as population for comparison, this paper finds that Korea has been lagging behind the group of developed countries in attracting FDIs, thereby having recorded negative aggregate industry-mix effects and negative aggregate competitive effects as well. However, the following industries have recorded positive competitive effects: textiles, chemicals, electrical and electronic equipment, motor vehicles and other transport equipment, hotels and restaurants and business services. Moreover, in the sub-period of 2008-2012, positive competitive effects have been recorded for most manufacturing industries. This reflects the fact that inward FDI into Korea has not been affected much by the financial crisis of 2009.

The Southeastern economic zone was centered on small and medium-sized manufacturing, but industrial changes and corona 19 caused the local economic downturn. This study presented the difficulties of companies related to the aviation specialization industry and suggested ways to revitalize the local economy in order to revitalize the local economy in the southeast region. First, aeronautical specialized parts companies need various support to improve the structural problems of passive industries. Second, the industry needs a systematic education system that develops products and technologies that meet international standards and conducts international certification education to support stable supply and demand of human resources by cultivating professional manpower for systematic project performance. Third, the industry needs financial and administrative support from the government to develop technologies and products that meet high standardization standards. In addition, it is necessary to provide support to systematically improve the limitations and difficulties of companies, such as finding and expanding customers of small and medium-sized companies and supporting investment for cost reduction.
