This paper conducts an empirical analysis to examine the tax effect on the basis (the difference between the futures price and the cash price) of KOSPI200 stock-index futures.

The standard cost-of-carry model relies on a simple non-arbitrage argument in which a trader replicates a “synthetic bond” with short in the futures and long in the underlying basket of cash stocks. While the synthetic bond provides the same or similar economic profiles as a normal interest-bearing instrument, the tax treatment for each is different under Korean tax code. The implicit taxes are expected to lower the before-tax rate of return on the synthetic bond, and thus to shrink the size of the basis.

The analysis indicates that implicit taxes are reflected and thus priced in the basis of KOSPI200 stock-index futures.

This paper aims to discuss the optimum design of a Maglev lift system's electromagnet to reduce the weight of the machine with constraint of normal force using response surface methodology (RSM).

The optimum design of Maglev lift system's electromagnet for weight reduction is performed by using RSM. The magnetostatic analysis of Maglev lift system's electromagnet is performed by using ANSYS.

The process is based on minimization of an appropriate objective function, while at each step the response is determined by the 3D finite element method (FEM).

It is necessary to compare normal force between the 3D FEM result and the experimental result of the manufactured model.

The paper deals with the possibility of using the RSM for optimization of an electromagnet with a higher number of the design variables.

Disaster risk reduction (DRR) technology sharing has emerged as an important global issue across national boundaries. As a result, the DRR technology-sharing environment needs strengthening based on the findings of difficulties in sharing, investment, and commitment. The purpose of this paper is to three fold: first, it will clarify that a web-based platform is the best conduit for linking DRR technology from the supplier to the beneficiary developing countries. Second, it will find the most evolutionary path based on Korean case studies. Finally, it will make recommendations for the efficient implementation of a web-based platform for DRR technology sharing.

This paper posits that DRR technology sharing is a necessary part of enhancing resilience to disasters in the Asia-Pacific region. The evolution of web-based approaches (a merchandise display-type platform, a journal-type platform, an electronic market-type platform, and an architecture and governance-type platform) and an actual case of space technology sharing providing support for an evolution toward community-based technology sharing in DRR. The research will find the most efficient way going forward based on the case study of a four-year R & D project sponsored by the South Korean Government. It will also find the success factors for the way to establish and operate the platform efficiently and effectively through case studies of the four types of web-based platforms.

Sharing of DRR technology through a web-based platform among Asia-Pacific countries is necessary in order to equip all parties with essential technology to mitigate intensifying disasters, to overcome the barriers of technology sharing, to breakdown transfer issues due to language barriers, and to strengthen insufficient DRR budgets. Among the four types of web-based platforms, the architecture and governance-type platform proved to be the most effective and efficient. In addition, four principles for an efficient implementation are identified through case studies, analysis, and research.

This paper reports on the reasons why it is difficult for DRR technology sharing in the Asia and Pacific regions and suggests a web-based DRR technology-sharing platform as a solution for the region. Moreover, it substantiates that the architecture and governance platform type as the most efficient and effective evolution with four principles: develop based on end-user’s needs; take a problem-solving approach; contain interactive communication tools; and provide business opportunity.
