During the global financial turmoil in 2007-2008, deviation from the covered interest parity (CIP) between the Korean won and US dollar through the foreign exchange swap has escalated in its magnitude beyond 1,000bp in November 2008, and it still persists around 100bp level. In this paper, we examine a newly developed margin based asset pricing model using Kalman filter approach and show that the escalation of the CIP deviation is found to be significantly related to the global dollar funding illiquidity and country-specific funding conditions. Furthermore, we find evidence that the poor funding conditions (or higher margins) are driven by the general money market illiquidity and may lead to higher funding illiquidity, which suggests the reinforcing effects of the liquidity spiral. We also show that the supply of dollar liquidity and improved funding conditions help alleviate the deviations from the parity, however the persistent anomaly is found to be related to the high level of volatility in the FX swap market.

Controversies over NEIS(Network of Education Information System) began with very deep concern about infringement of human rights stemming from NEIS. A large information system which accumulates and uses huge size of individual information is always able to deeply infringe on human rights. But the ministry of education would not do the best not to be 'Big Brother' being dazzled by instrumental efficiency of information technology. NEIS has demonstrated problems of the information policy of Korea strongly driven in the name of 'E-goverment'. It has very strong characteristic of the statist economic growth policy focusing on more economic possibility than other. In this situation, making money is easily considered more important than protecting human rights. Information capitalism is nurtured at the sacrifice of human rights. So, we have to face problems of 'E-goverment' in order to correct the NEIS problem, The most important task to correct the NEIS problem is to make an element law protecting privacy and to establish an independent national institute protecting privacy

The purpose of this study is to research the change of Tibet's commercial district following Tibet's globalization(traditional clothing to modern clothing). Tibet's traditional culture is fastly changing for two major reasons: Chinese government's persistent assimilation policy on minority ethnic groups and globalization, a powerful trend worldwide. Therefore this investigation was conducted on the most preeminent feature of life, clothing culture, at capital city Lhasa where modernization is most prominent and fast in Tibet. For this, the first field investigation was conducted between February 5th and 15th, 2007. and the second investgation was between January 16th and 25th, 2008. As a result, the study on clothing globalization in Lhasa, Tibet, reaches the conclusion as follows: Based on such developments, commerce of Lhasa has been modernized, bringing about great change in composition and formation of its commercial district. Stores have been modernized and their service quality has improved. While the number of traditional clothes shops has decreased, various types of modern clothes shops have emerged. Modern clothes stores mostly consist of quality men's wear shops, casual clothing shops targeting those in their 20s, and sportswear shops reflecting global trend. This composition indicates that it is men and younger generation who first adopt new culture emerged through globalization. Tibet's modernization and social development have become an integral part of globalization and public sentiment. Therefore, its modernization will be driven by power and capability of the public, rather than by policy control of the central government.

Considerable attention has been devoted in the accounting literature to identify the factors that cause or drive the costs of overhead activities. This paper extends recent cost driver research to the health care provider. In various case studies, it has been suggested that overhead costs are driven by volume and complexity variables. This paper investigates the significance of these variables in determining hospital overhead costs, how they are structurally related and how the cost impacts of these variables can be estimated in practice. This paper analyzes the determinants of hospital costs using the sample of South Korea hospitals for seven year during the period 1952－1997. The paper focuses on the extent to which hospital overhead costs depend on complexity, efficiency in addition to depending on more conventional volume based measures of hospital activity. The results of regression analysis suggest that volume and complexity factors positively and significantly affect overhead costs in the hospital industry. The results show that the complexity-related cost drivers strongly affected on the overhead costs in tile health care provider industry more than manufacturing industry which is mainly affected by volume-related cost drivers. That means each Industry may have different cost structures. Therefore it Is Important to find their proper cost structures and cost drivers and use them. Futhermore identification of overhead or indirect cost drivers is likely to be particularly useful in heath care. The identification of cost drivers can be of benefit to all health care stakeholders because these facilitates more efficient management of the national resources devoted to health care. While this study has documented that the level of service complexity is a significant determinant of hospital overhead costs, caution should be exercised in interpreting this as supportive of the cost accounting procedures associated with ABC. It is an open question whether even a well-designed ABC system will provide suitable proxies for marginal costs for decision making purposes.

In the emerging information society. a well-established national Information network plays a crucial role In enhancing economic efficiency and creating national wealth. Most of the advanced nations In the world are putting forward government-driven projects for the construction of their national Information Infrastructures. strategically focusing on the development of key technologies and Industrial essential for their Infrastructures. Development of the NII (National Infrastructure) can help unleash an Information revolution that will change forever the way people 1ive, work. and interact with each other. Nonetheless. the present Information Infrastructure In Korea loaves a lot to be Improved In order to realize the vision of Information society. The establishment of the KII (korea Information Infrastructure) does not merely mean the construction of physical network that enables the transmission of various modes of information such as voice, data, and image. It further implies the creation of a new kind of social overhead capital, ranging from the establishment of social and cultural which are conductive to seamless flow of information. For the successful implementation of the KII, it is critical to build the public consensus on the importance and necessity of informatization. At the same time, careful consideration should be given to the institutional factors such as timely and adequate supply of specialized personnel, the updating of policy and regulations, and the strengthening of interntional cooperation.

This paper aims at analyzing ways to utilize the capital market for expanding housing welfare, focusing on the case of the affordable housing REITs in the United States. The main results of this study are as follows. First, the United States converts the keynote of its housing welfare policy to the provision of affordable housing, through private operators, and operates various support systems, including the LHITC program for them. Second, under this institutional framework, the use of capital markets for affordable housing is actively carried out, especially through the provision of affordable housing REITs such as CDT and AIMCO. Third, the public- driven housing REITs model and the private-led housing REITs model were proposed as ways to utilize the capital market through affordable housing REITs in Korea. Finally, policy improvement ways were proposed to promote the use of the capital market of affordable housing REITs.

This paper measures the economic impacts of the U.S. port investment strategies coping with the Panama Canal expansion. Using secondary import data, negative and positive estimates of the impacts were presented in this study. Reduced port activities into the West Coast Customs Districts negatively affect transportation and warehousing industries, among other effects. Still, they have simultaneous positive effects in other states from increased imports resulting from modal shifts and changes in the entry port located in the South and East coasts. This study applied the supply-driven National Interstate Economic Model that measures all interstate trade among the U.S. states to divert foreign imports from 15 Pacific Rim countries. For this purpose, the following assumption was adopted: larger ships using the canal will lead to a redirection of seaborne trade among U.S. (and other) ports and result in secondary effects, e.g., using different freight modes and regional growth spillovers. This study also accounted for the entry point change and significant port investments for foreign trade under alternative scenarios. The choice of ports for international trade depends on decisions about how to minimize multimodal delivery costs. The total direct reduction of transportation and warehousing activities associated with foreign imports in the West Coast ports was estimated at $3.3 billion, leading to total negative effects of $5.8 billion. Total positive impacts from the shift of transportation modes with the choice of an entry port and new warehousing activities for foreign imports in the selected 12 states varied. As expected, states that involved an entry port had the most prominent benefits, but Texas, New York, and New Jersey may be benefited through all the port enhancement projects in the U.S. Also, except for Transportation and Postal, and Warehousing industries, Construction is another dominant positive affected industry of the Canal expansion in the U.S.

Background: Monitoring appropriate medication categories can provide early warning of certain disease outbreaks. This study aimed to present a methodology for selecting and monitoring medications relevant to the surveillance of acute respiratory tract infections, such as influenza. Methods: To estimate correlations between acute febrile respiratory tract infection and some medication categories, the cross-correlation coefficient (CCC) was used and established. Two databases were used: real-time prescription trend of antivirals, anti-inflammatory drugs, antibiotics using Drug Utilization Review Program between 2012 and 2015 and physicians' number of encounters with acute febrile respiratory tract infections such as influenza outbreaks using the national level health insurance claims data. The seasonality was also evaluated using the CCC. Results: After selecting six candidate diseases that require extensive monitoring, influenza with highly specific medical treatment according to the health insurance claims data and its medications were chosen as final candidates based on a data-driven approach. Antiviral medications and influenza were significantly correlated. Conclusion: An annual correlation was observed between influenza and antiviral medications, anti-inflammatory drugs. Suitable models should be established for syndromic surveillance of influenza.

Water quality models are scientific tools that simulate and interpret the relationship between physical, chemical and biological reactions to external pollutant loads in water systems. They are actively used as a key technology in environmental water management. With recent advances in computational power, water quality modeling technology has evolved into a coupled three-dimensional modeling of hydrodynamics, water quality, and ecological inputs. However, there is uncertainty in the simulated results due to the increasing model complexity, knowledge gaps in simulating complex aquatic ecosystem, and the distrust of stakeholders due to nontransparent modeling processes. These issues have become difficult obstacles for the practical use of water quality models in the water management decision process. The objectives of this paper were to review the theoretical background, needs, and development status of water quality modeling technology. Additionally, we present the potential future directions of water quality modeling technology as a scientific tool for national environmental water management. The main development directions can be summarized as follows: quantification of parameter sensitivities and model uncertainty, acquisition and use of high frequency and high resolution data based on IoT sensor technology, conjunctive use of mechanistic models and data-driven models, and securing transparency in the water quality modeling process. These advances in the field of water quality modeling warrant joint research with modeling experts, statisticians, and ecologists, combined with active communication between policy makers and stakeholders.
