금융투자상품 포괄주의 규율체계에 대한 입법적 보완에 관한 연구
이한진(Lee, Han Jin) 한국증권법학회 2014 증권법연구 Vol.15 No.3
This paper aimed to evaluate issues resulted from the comprehensive regulatory framework on financial investment products under the Financial Investment Service and Capital Market Act (FISCMA). Specifically, it focused on the policy intent and the principles of comprehensive regulatory framework, the comprehensive legal definition of financial investment products, the distinction between securities and derivatives, and the definition of derivatives combined securities and investment contract securities with a particular emphasis on the practical application. The policy intent of the comprehensive regulatory framework under the FISCMA was expanding the business scope of financial investment services providers while strengthening investor protection simultaneously. However, the principal limit, which governs the issuance and transfer of securities inscribed in the statutory law restricted the business scope of financial investment services providers. Further, the introduction of comprehensive regulatory framework saw a little deterioration in investor protection due to the increased level of issuances in long-term commercial paper. In addition, accomadative policy options for the ease of corporate funding were not fully addressed in the enactment of the FISCMA, which will increasingly necessitate further discussion. Despite some criticism from the academic world, the comprehensive legal definition of financial investment products was rather well received in the government practice. However, the lack of exemptions, which were witnessed in the US, the UK, Australia, etc from certain clauses requiring interpretation and application of the comprehensive legal definition increased regulatory uncertainties and burden on both the regulators and the regulated entities. The obligation for additional payments, which was the only criterion provided to distinguish derivatives from securities under the FISCMA, caused difficulties in the practical setting, particularly in the area of options and warrants. It was noted that the single criterion approach has been facing challenges due to the increasing demand on clear distinction between securities and derivatives as the regulatory requirements on derivatives has been heightened since the Global Financial Crisis. Various issues raised from derivatives combined securities and investment contract securities were also considered in relation to the application of the comprehensive legal definition of securities under the FISCMA. A particular consideration was given to the issuance and sales of derivatives combined securities as separate regulations govern them with different policy intent. It was noted that investment contract securities and the likes can cause further issues when combined with crowdfunding due to the lack of transferability. Finally, the contents and policy intent of the amendment to the FISCMA in 2013 along with the revised bills and its subordinate regulations, which aimed to clarify and supplement the comprehensive regulatory framework on financial investment products, are detailed with referece to the changes in the definition of financial investment products and in the classification criterion between securities and derivatives. Further, some issues arising from the amendments in the scope of the derivatives combined securities, investment contract securities, etc with reference to the amendment to Commercial Law in 2011 and the new legislation on crowdfunding, which is currently being discussed in the National Assembly, are also considered.
트리형 컴퓨터 네트워크 설계를 위한 유전자 접근방법의 성능 분석

This paper considers a topological optimization of a tree based network design with traffic capacity and mean packet delay constraints. The objective is to find the topological layout of links, at minimal cost. This problem is known to be NP-hard. To efficiently solve the problem, a tabu list coupled genetic algorithm approach is proposed. Illustrative examples are used to explain and test the proposed approach. Experimental results show evidence that the proposed approach performs more efficiently for finding a good solution or near optimal solution in comparison with a genetic approach.

This paper considers a topological optimization of a computer network design with a cost constraint. The objective is to find the topological layout of links, at maximal reliability, under the constraint that the network cost is less or equal than a given level of budget. This problem is known to be NP-hard. To efficiently solve the problem, a genetic approach is proposed. Two illustrative examples are used to explain and test the proposed approach. Experimental results show evidence that the proposed approach performs more efficiently for finding a good solution or near optimal solution in comparison with a simulated annealing method.

배달 애플리케이션과 지도 애플리케이션의 발달은 가게 이용에 많은 편리함을 가져왔지만, 푸드트럭, 포장마차와 같은 길거리 점포는 이러한 혜택의 사각지대로 이용에 많은 불편함이 남아있다. 이에 본 논문에서는 길거리 점포의 특성에 맞춘 위치기반 점포 관리 및 정보 제공애플리케이션을 설계하였다. 이에 이용자들이 보다 편리하게 길거리 점포를 이용할 수 있게 되기를 기대한다.
여러 링크 유형이 고려된 트리형 컴퓨터 네트워크의 경제적 설계

In this paper, we deal with the design problem of tree computer networks that addresses many of the practical concerns associated with local access network design. The design problem of tree computer networks can be defined as finding the tree network topology minimizing cost subject to mean packet delay and sub tree maximum traffic capacity constraints. So for the design problem has been studied for a single link type in the design of the network. In practice, it seems unreasonable to assume that only a single link type is available to the network planner. In this paper, we consider the design problem of tree computer networks, in which there are multiple link types with different capacities and costs that can be installed between two nodes in the network. To solve the design problem, a genetic algorithm approach is proposed. Two illustrative examples are used to explain and test the proposed approach.
