Trade remedy is the system that additional duty or import quantity restriction would be imposed on the import products, in case that unfair imports damage domestic industry or even proper import products damage significantly domestic industry. The system is secured by the act of unfair trade practice investigation & industrial damage remedy, tariff act, WTO agreement. Anti-dumping duty act is the system that duties are assessed with the equal or less amount of the difference between normal transaction price and dumping price, in case that the product imported under dumping price causes or may cause damages in domestic industry, or the development of domestic industry should be delayed practically. Recently, the problems related with anti-dumping duty imposed as the part of the trade remedy occur frequently. It is necessary to discuss whether the anti-dumping duty act is practically trade remedy which does comply with GATT regulations and WTO agreements as the criteria of international law and is in line with the intent of domestic act in the suffered country, or it does return to protective trade or reduce the protection of consumer. On the basis of this discussion, it would be difficult to impose the antidumping duty on industrial products in order to protect domestic industry, when considering the expected free trade agreements of Korea-US, Korea-China and Korea-Japan. In order to survive under the current severe competition of world trade market, companies should raise the competitiveness by themselves without relying on the current trade acts to provide with a certain protection. This thesis should bring those attentions.

This article analyzes the case (2008Da16776) which has the issue how patients have to prove causal relationship when patients claim against pharmaceutical companies alleging that patients were infected with virus due to contaminated blood products. The Supreme court held that: (1) if patients prove that they didn't have symptoms suggesting virus infection before administration of blood products, the virus infection had been confirmed after administration of blood products, and there were significant potential of contamination of the blood products with the virus, the defect in blood products or the negligence of pharmaceutical company in making blood products shall be presumed to cause the infection of the victim. (2) The pharmaceutical companies could reverse the presumption by proving the blood products were not contaminated, but the fact that the victims were treated with the blood products manufactured by other companies or had received blood transfusions is not enough to reverse the presumption. The case is the first decision whether the burden of proof about causal relationship could be reduced in pharmaceutical product liability lawsuit. Hereafter pharmaceutical product liability cases, it would be necessary to reduce the burden of proof about causal relationship in order to make substantive equality between patients and pharmaceutical companies.

The reed switch position transmitter (RSPT) is used as a position indicator for the control rod in commercial nuclear power plants made by ABB-CE. But this position indicator has some problems when directly adopting it to the integral reactor. The Control Element Drive Mechanism (CEDM) for the integral reactor is designed to raise and lower the control rod in steps of 2mm in order to satisfy the design features of the integral reactor which are the soluble boron free operation and the use of a nuclear heating for the reactor start-up. Therefore the resolution of the position indicator for the integral reactor should be achieved to sense the position of the control rod more precisely than that of the RSPT of the ABB-CE. This paper adopts seismic resistance reed switches to the position indicator in order to reduce the damages or impacts during the handling of the position indicator and earthquake.

Driven by the growing number of the mobile subscribers, efficient channel resource management plays a key role for provisioning multimedia service in the next generation personal communication systems. To reuse limited channel resources, diminishing the coverage areas of cells seems to be the ultimate solution. Thus, however, causes more handover events. To provide seamless connection environment for mobile terminals and applications, this article presents a novel handover scheme called the intelligent channel reservation (ICR) scheme, which exploits the location prediction technologies to accurately reserve channel resources for handover connections. Considering the fact that each mobile terminal has its individual mobility characteristic, the ICR scheme utilizes a channel reserving notification procedure (CRNP) to collect adequate parameters for predicting the future location of individual mobile terminals. These parameters will be utilized by the handover prediction function to estimate the expected handover blocking rate and the expected number of idle channels. Based on the handover prediction estimations, a cost function for calculating the damages from blocking the handover connections and idling channel resources, and a corresponding algorithm for minimizing the cost function are proposed. In addition, a guard channel decision maker (GCDM) determines the appropriate number of guard channels. The experimental results show that the ICR scheme does reduce the handover-blocking rate while keeping the number of idle channels small.

When a drought occurs in an area irrigated by multi-reservoirs, onerating a single reservoir separately to control the reservoir' storage is not a desirable solution. In order to reduce damages effectively for the areal drought, the storage of the reservoirs within the areal boundary should be managed as a group. Storage management procedures are as follows : 1. Collecting and checking the present storages of all reservoirs 2. Computing the drought frequency and depth; and finally, establishing a suitable storage saving strategy based on the estimated drought depth. For the purpose of this storage management, the RESTOMS(Reservoirs Storage Management System) was developed and the system was composed of the PRIME computer and the ORACLE as a distributed database management system, which was the host computer of Rural Development Corporation and would be on-lined with the regional offices throughout the country. Reservoirs operated by Farm Land Improvment Association were comprised in the DB system. Using the RESTOMS, the drought frequencies and drought depths were calculated with respect to the reservoir storage records(1967 to 1992). It was obvious that the results were closely corresponding to the real drought records.

In electronic ticketing system, the malicious behavior of scalpers damages the customer's interest and disturbs the normal order of market. In order to solve the problem of scalpers, we took two steps. Firstly, we established the electronic ticketing system based on the consortium blockchain (CB-ETS). By establishing CB-ETS, we can make the ticketing market develop better in a controlled environment and be managed by the members in the consortium blockchain. Secondly, we put forward a kind of taxation mechanism for suppressing scalpers based on CB-ETS. Together with the regulatory mechanism, our scheme can effectively reduce the scalpers' profits and further inhibit scalpers. Through the above two steps, the scheme can effectively resist the malicious behavior of scalpers. Among them, in the process of transferring tickets, we optimized the transfer mechanism to achieve a win-win situation. Finally, we analyzed the security and efficiency of our scheme. Our scheme realizes the anonymity through the mixed currency protocol based on ring signature and guarantees the unforgeability of tickets by multi-signature in the process of modifying the invalidity of tickets. It also could resist to Dos attacks and Double-Spending attacks. The efficiency analysis shows that our scheme is significantly superior to relevant works.

Medical supplies have contradiction of efficacy and side effect to the various diseases together. Therefore, people have tried to reduce the side effects and also provide various methods to cope with any damages from the medicine quickly. In the case of accidents by medical supplies, the victim can be protected with advantage by the Product Liability Law rather than the Torts. The limit of Product Liability Law's application depends on whether medical supplies belong to the product or not. According to Product Liability Law, the product should be processed. Therefore, medical supplied should be processed to be the category of product. It can be said that the medical supplies in pharmacy, Chinese medicine, medical herbs, biological medicine manufactures, blood manufactured medicine, cord blood, hemopoietic progenitior cell and stem cell belongs to the manufactured products. The mixture by the prescription of doctor or preparation of pharmacist can be recognized as the product because prescription or preparation is a manufacturing act. Therefore, applying Product Liability Law to manufacturer, doctor or pharmacist would achieve the goal which is protecting the victims extensively.

Low rise masonry structures are relatively inexpensive and easier to construct compared to other types of structures such as steel and reinforced concrete buildings. However, masonry structures are relatively heavier and less ductile and more vulnerable to damages in earthquakes. In this research, a new innovative low-cost seismic isolator using steel rings (SISR) is employed to reduce the seismic vulnerability of masonry structures. FEA of a masonry structure, made of concrete blocks is used to evaluate the effect of the proposed SISR on the seismic response of the structure. Two systems, fixed base and isolated from the base with the proposed SISRs, are considered. Micro-element approach and ABAQUS software are used for structural modeling. The nonlinear structural parameters of the SISRs, extracted from a recent experimental study by the authors, are used in numerical modeling. The masonry structure is studied in two separate modes, fixed base and isolated base with the proposed SISRs, under Erzincan and Imperial Valley-06 earthquakes. The accelerated response at the roof level, as well as the deformation in the masonry walls, are the parameters to assess the effect of the proposed SISRs. The results show a highly improved performance of the masonry structure with the SISRs.

A press-fitted shaft is an essential part used in industrial machines, and it is generally used to transmit large quantities of power. Very high contact pressure occurs at the end parts of the contact between the shaft and boss, which are press-fitted shaft components. Such contact pressure not only damages the contact surface of a press-fitted shaft but also reduces its fatigue strength. To improve a press-fitted shaft's fatigue strength, the contact pressure on the contact surface, which directly affects the fatigue strength, should be minimized. Thus, in this study, the design configuration optimization of the end part of the boss was based on the approximate optimization method and was aimed at minimizing the contact pressure at the end of a press-fitted shaft. Comparison of the contact pressure and the contact stress of a conventional press-fitted shaft with those of the optimized press-fitted shaft showed that the boss design of the optimized press-fitted shaft effectively improved the fatigue life.

In mass casualty situation due to radiological accidents, it is important to start aggressive management with rapid triage decisions. External contamination needs immediate decontamination and internal contamination should be treated with special expertise and equipment to prevent the rapid uptake of radionuclides by target organs. Acute radiation syndrome shows a sequence of events that varies with the severity of the exposure. More severe exposures generally lead to more rapid onset of symptoms and severe clinical findings. After the massive exposure, various systems of the body reflect their severe damages that can lead to death within hours or up to several months. The disease progression has classically been divided into four stages: prodromal, latent, manifest illness, and recovery or death. Three characteristic clusters of symptoms including the hematopoietic syndrome, the gastrointestinal syndrome and the cerebrovascular syndrome are all associated with the acute radiation syndrome. The standard medical management of the patients with a potentially survivable radiation exposure includes good medical, surgical and supportive measures. Specific treatment with cytokines and bone marrow transplantation should be considered. The management of internal contamination is much the same as the treatment of poisoning. The standard decontamination should be applied to reduce uptake, and the chelating agents can be administered to enhance the clearance of radioisotopes. Radioactive iodine ($^{131}I$) as one of the nuclear fission products can increase the incidence of thyroid cancer in children. Potential benefit of potassium iodide prophylaxis is greater especially in neonates, infants and small children.
