An investigation was conducted to know a prospect of woody toy in Korea for physical, psychological and intellectual development. It was told that toys that stimulate cognitive development are appropriate for the child's capabilities, responsive to the child's movements, provide feedback when manipulated, and require imagination or fantasy. Toys particularly useful in the development of these abilities include dolls, figures, cuddly toys, puppets, costumes, and construction toys. Therefore, a toy is a wonderful object, indispensable to physical, psychological and intellectual development, both for those who have the capacity to integrate into society and for those who encounter difficulties. If we can replace a plastic toys by a environmental wooden toys, we can contribute to child development that is especially to promote creativity, artistic, problem-solving, language and social skills. In addition, we can support the ability of wood toy manufacturers to market their products in a responsible way and contribute to strengthen the competitiveness of our commodities on international markets.

Often in practice, the implied volatility of an option is calculated to find the option price tomorrow or the prices of, nearby' options. To show that one does not need to adhere to the Black- Scholes formula in this scheme, Figlewski has provided a new pricing formula and has shown that his, alternating passive model' performs as well as the Black-Scholes formula [8]. The Figlewski model was modified by Henderson et al. so that the formula would have no static arbitrage [10]. In this paper, we show how to construct a huge class of such static no arbitrage pricing functions, making use of distortions, coherent risk measures and the pricing theory in incomplete markets by Carr et al. [4]. Through this construction, we provide a more elaborate static no arbitrage pricing formula than Black-Sholes in the above scheme. Moreover, using our pricing formula, we find a volatility curve which fits with striking accuracy the synthetic data used by Henderson et al. [10].

Nowadays tiles are widely used as architectual material because of their external beauty, solidity with fire-resisting and water-resisting qualities, and convenience for construction, preservation and repairs. Owing to the improvement of living standard and makers scramble for tile markets, we regard tiles as art and culture. Tiles have been developed with technical improvement, based on mutual relation of material and design. The purpose of the third firing is to create high value added as we show artistic merit and decorative effect. For this reason, researches on new material and design have been carried out widely. I made researches whole process from design to printing by means of computer and experiment with color and vetroza of the third firing. I hope that tile makers will share the achievement of university researchers and this paper will be useful for those who are interested in tiles.

The importance of renewable energy technology is discussed and next generation power transmission networks, which is called the smart grid, are constructed in developed countries. However for construction and operation of the smart grid, it is required not only to develop the electrical power generation technologies and transmission equipments but also to study systematic analysis and optimization for design and operation of the smart grid. In this paper we study electrical power trade in the smart grid using operations research models and simulation methods. We also consider future electrical power exchange markets in Korea and build four scenarios and the related optimization and simulation models, which reflect electrical power transaction pricing strategies of stake-holders. We can also simulate electrical power exchange market and analyze the results of electrical power trading, which can give us some insights for future electrical power exchange market.

While large-sized facilities (type I II) have been managed systematically after the establishment of the Special Law for Safety Management on Facility, the management of small-sized facilities is relatively poor. The small-sized facilities have been managed by The Basic Law for Disaster and Safety Management, however, it is hard to manage them systematically as related standards are not established. Therefore, this study proposed the management plans for including the facilities such as some road tunnels and utility tunnels, which have the definite manager and a high possibility to harm the public, into type I and II facilities. In addition, it proposed the reinforcement plans of safety management for small-sized and vulnerable facilities such as breast wall and cut slopes, traditional markets and pedestrian bridges, which are fundamental facilities closely related to people's life, although a budget and a man-power are not enough.

The procurement of generation and transmission/Distribution capacity in vertically-integrated electric industry is sufficient by facility construction in suitable time. However, the introduction of competitive electricity market increase the efficiency of availability for facilities and fuels. As a result, long-term capacity procurement is required for stable demand-supply balance since it is expected to maintain their generation capacity at a minimum for profit maximization. In this paper, a new long-term capacity procurement mechanism is proposed, which is able to assure supplemental contribution in competitive electricity market.

This article aimed to investigate problems relating to medical tourism based on a review of medical tourism reports and statistics in the global healthcare industry. To be a leading nation in the global healthcare industry, the needs and culture of many peoples, including Muslims, should be considered. Qualified medical services by JCI certification, including nutrition services, will provide opportunities to participate in the international and Asia medical tourism markets. In this article, the definitions of medical tourism, medical service, Halal and Haram, nutrition service for inbound Muslim patients, and Halal food supply in Korea were examined for medical service improvement. Mutual assistance between the government and private enterprise, sharing of medical service information, and construction of a cooperative network system are needed and should be supported by the government.

How do we build our future society for next 20 years? Such a country as Korea having only human resources, that was coupled with country's growth potential from the agronomical to the manufacturing industrial in the past decades, is entering into era of information society backed by knowledge - based industry as a country as a country with one of the maost advanced information technology markets in the world, playing a key driving force for Korean economy with the development of IT, BT, ITS. UT and e-construction which are this country's top strategic industries leading to a build-up of New Korea through those technological innovations being the essential in everyone's living for next 20 years.
