In December 2020, the Fair Trade Act related to South Korea's separation of industrial capital was amended, and it was announced that the amendments would come into effect one year later, on December 30, 2021. The amendment's content involved breaking the previous principle of separating industrial capital from financial market penetration, allowing for the ownership of shares in general holding companies, small business startup investment companies, and technology business finance specialist companies. While the previous law was based on total issued shares' ownership, there were fluctuations in the subsequent trends of annual establishment and investment counts, as well as strategic investment counts of CVC (Corporate Venture Capital) before and after the law's amendment. CVC and IVC (Independent Venture Capital) are characterized differently based on their investment purposes, fund management types, and investment types. In this regard, the relaxation of the separation of industrial capital law is expected to have a positive impact on the future of the venture investment ecosystem and innovation ecosystem. In this study, we analyze the trends in the establishment count, investment count, and strategic investment count of domestic CVC from 2018, before the law amendment, to May 2023. Using 2021, the year the amended separation of industrial capital law was implemented, as a reference point, we examine changes in the trend. The analysis results indicate a significant increase in domestic CVC in 2021 compared to the previous year, along with an increase in investment counts, strategic investment counts, and the amount of investment in strategic investments. Based on these findings, this study suggests directions for further research related to future domestic CVC investment, strategic investment, and the activation of the venture investment market.

우리나라의 방송콘텐츠 시장은 2012년까지 연평균 성장률 3.5% 수준에 머무를 것으로 전망되고 있다. 원인으로는 콘텐츠 산업의 높은 파급효과에도 불구하고 영세한 제작환경 및 유통구조로 인해 양적/질적 측면에서의 낙후성을 벗어나지 못하는 것을 들 수 있다. 이는 경쟁 활성화를 가로막는 규제제도, 방송통신 플랫폼 사업자와 콘텐츠 제작자간 불공정 거래, 콘텐츠 제작자의 영세성 등에 기인한다. 이러한 우리 방송 환경을 고려할 때 신디케이트 도입은 성숙되지 않은 콘텐츠산업에 새로운 동력을 공급하는 계기가 될 것이다. 이러한 신디케이트 중 '온라인신디케이트'라는 것은 방송콘텐츠 유통전문기관을 설립함으로써 방송통신콘텐츠 판매창구를 개발하고, 제작사의 이익을 보장하며, 수요자에게 안정적으로 콘텐츠를 공급할 수 있다. 뿐만 아니라 국내외 시장 개척을 통해서 보다 확장된 창구화 효과를 거둘 수 있고, 현재의 변화된 방송환경에 맞추어 체계적이며 안정적인 공급과 판매를 통해서 우리나라 방송통신콘텐츠 산업 발전에 크게 이바지 할 수 있을 것으로 기대한다. 또한 방송통신콘텐츠 제작의 활성화와 유통구조의 개선은 전 세계를 대상으로 글로벌콘텐츠를 판매할 수 있어야 함으로 국제적 유통망 구축이 필수적이라고 할 수 있다. 그러므로 온라인신디케이트는 국제적 유통망구축에 효과적이며 결국 유통과 제작, 제작과 유통이 상호간 높은 관련성을 의미한다. 향 후 프로그램의 제작은 해외의 수출시장 파악이 우선이다. 그 후 국내 프로그램의 유통 성공여부를 가름하고, 해당 국가의 유통시장을 면밀히 분석할 필요가 있으며, 필요하다면 현지 유통사 및 제작사와 협력관계를 유지할 필요가 있다. 최종적으로 성공가능성을 타진하여 현지 유통사를 인수하는 것이 위험 부담을 크기 때문에 이러한 과정을 통해서 글로벌 유통기업을 만들어야 하나, 설립은 막대한 자금이 필요하므로 이러한 '온라인 유통공사(신디케이트)의 설립'은 처음 시작해야 하는 위험 부담을 줄이는 지름길일 것이다.

Nowadays various new items are available, but limitation of searching effort makes it difficult for customers to search new items which they want to purchase. Therefore new item providers and customers need recommendation systems which recommend right items for right customers. In this research, we focus on the new item recommendation issue, and suggest preference boundary- based procedures which extend traditional content-based algorithm. We introduce the concept of preference boundary in a feature space to recommend new items. To find the preference boundary of a target customer, we suggest heuristic algorithms to find the centroid and the radius of preference boundary. To evaluate the performance of suggested procedures, we have conducted several experiments using real mobile transaction data and analyzed their results. Some discussions about our experimental results are also given with a further research area.

Recently, business environment is spreading from singular business to supply-chain problem. SCM(Supply Chain Management) is changing from closed and static to opened and dynamic environment, so these environment changes of SCM require to enterprise different approach than past. As supply chain is becoming opened and dynamic, a claim is being naming that converse of real-time the get reaction from to recognizing the level of supply chain problem, grope of alternative plan to solving this problem and choosing optimum alternative plan raise the enterprise competitive. But until present, the research to deal with these changes of SCM is on insufficient situation. Thus in this paper proposes the agent system by a way of realizing dynamic supply chain. The agent is going to accomplish the management activities in real-time depends on environment and given condition and designed for solving problems development and maintenance. Also, algorithms performance of the agent is tested on TAC SCM environment. Agents in TAC SCM are simulations of small manufacturers, who must compete with each other for both supplies and customers, and manage inventories and production facilities.

We analyze the learning-by-doing effects of the allowance pricing system on the Korea's emission trading scheme. The price of allowance (Korean Allowance Unit) is influenced differently by internal market factors and economic conditions variables in the first (January 2015 to June 2016 ) and the second commitment year(January 2016 to June 2017). The prices and transaction volumes of complementary credits (KCU and KOC) as well as economic conditions variables (such as call rate, exchange rate, stock price) are statistically significant only for the second commitment year. Thus, the learning-by-doing effect makes the market participation decision on K-ETS market more efficient in the second commitment year, adopting the previous experience and knowledge in the K-ETS market. The factors estimated significantly in both commitment periods include the institutional binary variable for requiring the submission of the emissions verification reports issued both on February and March.
