  • This study estimates and evaluates the extreme value of 30 m-resolution daily maximum and minimum temperatures over South Korea, using inverse distance weighting (IDW), parameter-elevation regression on independent slopes model (PRISM) and generalized extreme value (GEV) method. The three experiments are designed and performed to find the optimal estimation strategy to obtain extreme value. First experiment (EXP1) applies GEV firstly to automated surface observing system (ASOS) to estimate extreme value and then applies IDW to produce high-resolution extreme values. Second experiment (EXP2) is same as EXP1, but using PRISM to make the high-resolution extreme value instead of IDW. Third experiment (EXP3) firstly applies PRISM to ASOS to produce the high-resolution temperature field, and then applies GEV method to make high resolution extreme value data. By comparing these 3 experiments with extreme values obtained from observation data, we find that EXP3 shows the best performance to estimate extreme values of maximum and minimum temperatures, followed by EXP1 and EXP2. It is revealed that EXP1 and EXP2 have a limitation to estimate the extreme value at each grid point correctly because the extreme values of these experiments with 30 m-resolution are calculated from only 60 extreme values obtained from ASOS. On the other hand, the extreme value of EXP3 is similar to observation compared to others, since EXP3 produces 30m-resolution daily temperature through PRISM, and then applies GEV to that result at each grid point. This result indicates that the quality of statistically produced high-resolution extreme values which are estimated from observation data is different depending on the combination and procedure order of statistical methods.

  • Korean Government is increasingly focusing on the Northeast Asia Business and Logistics Hub strategy to create a competitive advantage. A key element of this strategy is creating or leveraging distribution and logistics hubs that act as centres for distribution in Northeast Asia. A Northeast Asian e-Hub Policy is required for business hub and logistics hub in the Northeastern Asia. An e-Hub is an integrated, sophisticated set of e-Biz, information and e-trade facilities and services that provides access to a marketplace and exchangee the e-trade data. To study the e-Hub policy, Pan Asian e-Commerce Alliance, Korea-Japan e-Trade Hub project, and ASEM e-Trade project are considered. E-trade via cyberspace may need new methods of dispute resolution to reduce transaction costs for small value-related disputes and to erect structures that work well across national boundaries. Voluntary Mediation Councils and cyber tribunals should be encouraged by governmental sectors to continue developing private sector mechanisms to resolve e-trade disputes. Government-sponsored online cross-border dispute resolution systems may be also be useful to complement these private sector approaches. E-trade in Northeast Asia results in disputes owing to the incompleteness of e-trade law in the countries. These disputes contain disputes regarding e-trade model, central title registry, authentication body. To resolve these disputes in the Northeast Asia, a variety of electronic alternative dispute resolution bodies must be organized under cooperation of Korea, Japan, China. This study deals with the e-ADR construction in the Northeast Asia to resolve the disputes in the e-trade and to activate the e-trade in the Northeast Asia.

  • This paper analyzes the contents and the effects of the UNSC 2270, and its implications to South Korea's defense strategy and navy. The UN Security Council passed strong sanctions against North Korea which punish North Korea's 4th nuclear test. The sanctions compared to the previous ones require international society to take practical actions such as comprehensive trade bans as well as diplomatic isolation which will put significant pains on North Korea. Especially, these measures would greatly hamper economic development policy of Kim Joung-un regime. Because Kim Jung-un regime has inherent legitimacy problems which stems from the third family succession of the power, economic difficulties may play an important cause on the regime instability in the long term. In fact, the United States sees this possibility as an option to coerce North Korea in which North Korea choose denuclearization for its regime survival. Nevertheless, the prospects of the UN sanctions are not so optimistic. Considering North Korea's willingness for nuclear development and its level of nuclear technology, North Korea will try to play a gambit with the US and South Korea by exploiting its strategic advantages. North Korea's response will have three following strategies. First, it would actively pursue political and economic survival strategy by using China's support for the regime, strengthening its power grip in the name of countering US hostile policy, and enhancing peace propaganda. Second, North Korea will accelerate efforts to position its status as a nuclear de facto state. For this purpose, it could create nuclear crisis on the peninsula. Third, it would exploit local provocations as an exit strategy to get over the current situation. In order to counter North Korea's actions and punish North Korea's behavior strongly, South Korea needs following strategies and efforts. It should first make all the efforts to implement the UN sanctions. Strong and practical nuclear deterrence strategy and capability with the U.S. should be developed. Effective strategy and capabilities for the prevention and deterrence of North Korea's provocation should be prepared. For this purpose, North Korea's provocation strategy should be thoroughly reviewed. Active international cooperation is needed to punish and coerce North Korea's behavior. Finally, South Korea should prepare for the possible occurrence of North Korea's contingency and make use of the situation as an opportunity to achieve unification. All these strategies and efforts demand the more active roles and missions of South Korea's navy and thus, nullify North Korea's intention militarily.

  • Wireless sensor networks (WSNs) have emerged as a novel solution to many of the challenges of structural health monitoring (SHM) in civil engineering structures. While research projects using WSNs are ongoing worldwide, implementations of WSNs on full-scale structures are limited. In this study, a WSN is deployed on a full-scale 17.3m-long, 11-bay highway sign support structure to investigate the ability to use vibration response data to detect damage induced in the structure. A multi-level damage detection strategy is employed for this structure: the Angle-between-String-and-Horizon (ASH) flexibility-based algorithm as the Level I and the Axial Strain (AS) flexibility-based algorithm as the Level II. For the proposed multi-level damage detection strategy, a coarse resolution Level I damage detection will be conducted first to detect the damaged region(s). Subsequently, a fine resolution Level II damage detection will be conducted in the damaged region(s) to locate the damaged element(s). Several damage cases are created on the full-scale highway sign support structure to validate the multi-level detection strategy. The multi-level damage detection strategy is shown to be successful in detecting damage in the structure in these cases.

  • The equipment and techniques associated with magnetic resonance imaging (MRI) have rapidly evolved. The development of 3.0 Tesla MRI has enabled high-resolution imaging of the intracranial vessel wall. High-resolution MRI (HRMRI) can yield excellent visualization of both the arterial wall and lumen, thus facilitating the detection of the primary and secondary features of intracranial arterial dissection. In the present report, we describe the manner in which HRMRI affected our endovascular treatment planning strategy in 2 cases with unruptured intracranial vertebral artery dissection aneurysm. HRMRI provides further information about the vessel wall and the lumen of the unruptured intracranial vertebral artery dissecting aneurysm, which was treated by an endovascular approach in the 2 current cases.

  • KOMPSAT-3 is expected to provide data with 80-cm spatial resolution, which can be used to detect environmental change and create thematic maps such as land-use and land-cover maps. However, to analyze environmental change, change-detection technologies that use multi-resolution and high-resolution satellite images simultaneously must be developed and linked to each other. This paper describes a GIS-based strategy and methodology for revealing global and local environmental change. In the pre-processing step, we performed geometric correction using satellite, auxiliary, and training data and created a new classification system. We also describe the available technology for connecting global and local change-detection analysis.

  • The state adopts the policies based on the goals pursued by the state and provides a basic policy for administrative activities related to early childhood education. Therefore, early childhood education policy should be established organically in consultant with the social consent in advance. In most countries will bear the costs of child care and early childhood education can reduce the financial burden of parents and early childhood education consumers are able to understand the will of the government to support the child care services, which they need in a variety of way. The conflict is deepening - among policy officials, front-line institutions participating in policy implementation, and parents - surrounding the infant and early childhood education. And the conflict has caused the difference between this policy and claims that cannot find hardly a solution. In this study, we argue how the policy differences between groups involved in the policy to analyze the influence, to find the policy conflict resolution strategies.

  • An arbitration has great strength in the sense that it is a more rapid dispute resolution than a trial, and is means of dispute settlement for an achievement of the purpose which is the improvement of the rights and interests of consumers. Because the remedy of consumers' damage currently has not worked well, discussions about consumer arbitration as a universal Alternative Dispute Resolution (ADR) is needed. The core of the ADR is not only the professionality and neutrality of an arbitrator and a mediator, but also the non-impairment of the arbitration proceeding's fairness. In addition, it also has both economic feasibility and efficiency. Furthermore, providing an institutional strategy is necessary to ensure fairness in an arbitration award.
