To have global competitiveness in newly growing industry, good quality R&D's in convergence technology arerequired. Korean government also started to emphasize the importance of convergence technology as a new engine of growth for the future development. Since 2008, worldwide energy crisis and concerns on low carbon green growth made people focus on the convergence between information technology (IT) and energy technology (ET). However, the R&D performance comparison among the convergence technologies is not well explored so far. Therefore, this study uses Korea's patent citation database to measure the R&D performance of convergence technologies. We adopt technology development cycle, technology spillover analysis, and technology diffusion analysis to see the knowledge flow from R&D industry to others. We find that IT_ET convergence technology generally shows higher R&D performance than other convergence technologies. Contrary to public belief, convergence R&D by big companies has relatively low performance especially measures in technology spillover and technology diffusion. This implies that they might concentrate on delicate Fuel Cell Energy/Environment Technology (FEIT) or Nano Environment/Energy Information Technology (NEIT) rather than general energy information technologies. We also find that Korea's chemical industry may play a crucial role for the growth of other convergence technologies.

Since the global financial crisis, funding for startups or ventures has been diminished seriously. In this situation, crowd-funding has attracted worldwide attention as a viable means to financing startups/ventures. After reviewing existing laws in other countries, this study investigated the current status of crowd-funding legalization in Korea and surveyed requirements from three groups of participants to crowd-funding. Investors already recognized the high risk of crowd-funding into startups and asked for the protection of their investment. But, their priorities were on the enlargement of tax benefits and the establishment of a trading market for selling their equity. In addition, investors wanted to shorten the compulsory holding period. Issuers as fund raisers hoped fast legalization, convenient process of crowd-funding, and expansion of government support. Crowd-funding platform operators requested policies for establishing paths to become new growth companies from startups, tax benefits, and the setup of separate fund for startups. Currently, the National Assembly in Korea is holding the discussion on the submitted law. For desirable outcomes to all participants, it would be better to proceed in the following sequence. First, legalize the crowd-funding with clauses protecting investors; Second, encourage investment through tax benefits; Third, develop communities among participants for reducing information asymmetry; And fourth, establish diverse trading markets for selling equities of startups.

Various estimators of two risk measures of a specific financial portfolio, Value-at-Risk and Expected Shortfall, are compared for each case of 1-day and 10-day horizons. We use the Korea Composite Stock Price Index data of 20-year period including the year 2008 of the global financial crisis. Indexes of five foreign stock markets are also used for the empirical comparison study. The estimator considering both the heavy tail of loss distribution and the conditional heteroscedasticity of time series is of main concern, while other standard and new estimators are considered too. We investigate which estimator is best for the Korean stock market and which one shows the best overall performance.

This research analyzes the recent phenomenon of pursuing public benefit in fashion enterprises according to the increasing importance of corporate social responsibility attitudes towards the global sustainability crisis. The pursuit of public benefit in fashion enterprises has been realized by the activities that contribute to public welfare through one or plural corporations aligned with government, social corporations, and NGOs. The goals of public beneficial activities are to promote public issues and to support the underprivileged and communities both financially and voluntarily. Such activities can be categorized as philanthropy, sponsorship, social marketing, cause-related marketing, and public benefit product development. Especially public beneficial activities in fashion enterprises are featured as the charity donations of apparel products, the collaboration with fashion celebrities and artists in relation with popular culture and art, the limited edition of excellent design with slogans, and the visual campaigns to promote public issues. They deal with human right issues for the underprivileged and disease prevention issues. In addition, specially environmental issue and community trade issues (often raised in the fashion manufacturing and consuming process) are increasing.

Korea's economy has shown recovery since the global financial crisis in 2008. In the year 2010, Korea's export volume reached US D 467.4 billion and Korea is one of the main producer of IT equipment, electronics, ship-buildings, chemicals and automobiles. In particular, IT industry is one of the largest portion in Korea's export industries. The reason of the performance is that we develop innovative products to overseas markets and continued it. Also, there has been export support or promotion scheme in Korea. In this study, We need to evaluate the current system of export support and derive future challenges. This article has been studied to investigate relationship between export promotion and export performance. So, We classify export promotion program into 7 group(IT package, Market pioneers, Overseas exhibition, consultation invited buyers, International IT market research, Small Business IT export counseling center, Overseas marketing online) and the export performance was considered as the dependent variable. So the result are as follows. Factors on IT package, Market pioneers, overseas exhibition, International IT market research have been identified as influencing. and consultation invited buyers, Small Business IT export counseling center and Overseas marketing online have been identified as unimportant factor. So, We have to develop those Factors(IT package, Market pioneers, overseas exhibition, International IT market research) in the direction of strengthening the development of export support scheme.

CEPA(Comprehensive Economic Partnership Agreement, hereinafter CEPA) between India and Korea may influence some changes on Korean pharmaceutical industry which shows less competitive advantages than Indian industry in many regards. So the purpose of this paper remains on suggesting the way of enhancing international competitiveness for Korean industry on the basis of double diamond model. Through the comprehensive and deep analysis, our findings on recommendable business strategies for Korea are as follows ; in terms of factor conditions, first, cooperative strategy in R&D for developing generics will be required. Second, Introduction of CMO business can be considered. In terms of demand condition, Korean firms should find out the chance for demand creation in Indian market which has future market potential and American market exploration, as soon as possible. With regards to strategy, structure and competition, trying M&A with leading Indian companies and utilizing well organized medical professionals in India will be considered. In the points of related and supportive parts, lastly, Korean government should try to make so called "National Strategic R&D committee" for pharmaceuticals and bring u-healthcare service to Korea in the first place. If Korean pharmaceutical industry implement above-mentioned strategies, CEPA can be turned into business opportunities from the crisis. As a result, Korean firms shall have more powerful global competitiveness eventually.

Shipbuilding industry is one of the most influential ones in Korea. As shipbuilding industry is labor-intensive, it contributes to enhancing both local economy and national economy. Shipbuilding industry has been downsizing since the end of 2008 due to global financial crisis caused by America's sub-prime mortgage and aggravated by European countries' fiscal deficit. As a large fund is required for a single normal shipbuilding contract, fund raising is one of the most important elements in shipbuilding contract. Shipbuilding contract, requires refund guarantee in order for a buyer to reimburse the progressive payment paid to a builder. The disputes under shipbuilding contracts are mostly settled by arbitration rather than by law suit. English laws and English courts have been preferred for the choice of law as well as for the choice of forum. Due to depreciation of the ship value since the end of 2008, a number of buyers are trying to cancel the contract by raising unjust claim under the contract. Once disputes occurs regarding shipbuilding contract, a large amount of loss is inevitable. In order to mitigate the disputes arising from the shipbuilding contract, careful caution is required in drafting a shipbuilding contract.

In early 90s the worldwide awareness about the energy crisis and global warming had been increased and emission reduction (by improving energy efficiency), as well as increasing the capacity of clean and renewable energies, showed themselves as the most important steps towards the sustainable development approach. However, investigations on Iran's environmental situation show huge decline in recent decades and apparently there is no sense of urgency about these issues through the vision of Iranian politicians. In this article the idea of replacing the old gas turbines of Polkalleh natural gas compressor station - as one of the main compressor stations of Iran - with newer and more efficient gas turbines is evaluated, emphatically for reducing greenhouse gases emissions and their environmental costs and decreasing natural gas consumption as well. Clearly such idea is costly, but analyzing its economic impacts, huge declines in annual costs and greenhouse gases emissions can be seen as well. So an investment about $95 million can decrease 40% of Polkalleh compressor station annual costs, 25% of natural consumption and 30% of $CO_2$ and $NO_x$ emissions. Besides the simple payback period of this investment is about 2.5 years from the cut-expenses of annual costs.
