  • This study was conducted to determine the distribution patterns and duration of stay of Toxocara cati larvae in organs of chickens and to investigate chronic phase and potential zoonotic risk of toxocariasis in chickens. Chickens were orally infected with 1,000 embryonated T. cati eggs and necropsied 240 days post-infection. Organs of the chickens were examined at gross and microscopic levels; tissues were digested to recover larvae. Peribronchiolitis with infiltration of lymphocytes, and hyperplasia of bronchiolar associated lymphatic tissues (BALT) and goblet cells, were evident in the lungs of infected chickens. There were mild hemorrhages and infiltration of lymphocytes and a few eosinophils in the meninges. Larvae were recovered from 30% of the exposed chickens. Larvae recovery indicated that T. cati larvae stay alive for at least 240 days in the chicken brain. Therefore, chickens may potentially act as a paratenic host in nature and transfer T. cati larvae to other hosts.

  • Effectiveness of transgene transfer into genome is crucially concerned in mass production of the bio-pharmaceuticals using genetically modified transgenic animals as a bioreactor. Recently, the mammary gland has been considered as a potential bioreactor for the mass production of the bio-pharmaceuticals, which appears to be capable of appropriate post-translational modifications of recombinant proteins. The mammary gland tissue specific vector system may be helpful in solving serious physiological disturbance problems which have been a major obstacle in successful production of transgenic animals. In this study, to minimize physiological disturbance caused by constitutive over-expression of the exogenous gene, we constructed new retrovirus vector system designed for mammary gland-specific expression of the hEPO gene. Using piggyBac vector system, we designed to express hEPO gene under the control of mammary gland tissue specific and lactogenic hormonal inducible goat ${\beta}$-casein or mouse Whey Acidic Protein (mWAP) promoter. Inducible expression of the hEPO gene was confirmed using RT-PCR and ELISA in the mouse mammary gland cells treated with lactogenic hormone. We expect the vector system may optimize production efficiency of transgenic animal and reduce the risk of global expression of transgene.

  • The risk of progressive collapse in steel framed buildings under fire conditions is gradually rising due to the increasing use of combustible materials. The fire resistance of such steel framed buildings is evaluated by fire tests. Recently, the application of performance based fire engineering makes it easier to evaluate the fire resistance owing to various engineering techniques and fire science. The fire resistance of steel structural members can be evaluated by the comparison of the limiting temperatures and maximum temperatures of structural steel members. The limiting temperature is derived at the moment that the failure of structural member results from the rise in temperature and the maximum temperature is calculated by using a heat transfer analysis. To obtain the limiting temperatures for structural steel of grades SS400 and SM490 in Korea, tensile strength tests of coupons at high temperature were conducted. The limiting temperatures obtained by the tensile coupon tests were compared with the limiting temperatures reported in the literature and the results of column fire tests under four types of loading with different load ratios. Simple limiting temperature formulas for SS400 and SM490 steel based on the fire tests of the tensile coupons are proposed. The limiting temperature predictions using the proposed formulas were proven to be conservative in comparison with those obtained from H-section and hollow section column fire tests.

  • In Mash & Murrell, Diplock J said that "there is an implied warranty not merely that they shall be merchantable at the time they are put on the vessel, but that they shall be in such a state that they can endure the normal journey and be in a merchantable condition upon arrival." But in The Mercini Lady, Field J said that "the goods would be of satisfactory quality not only when the goods were delivered on to the vessel but also for a reasonable time thereafter." and "The proposed conditions were not excluded by clause 18. ${\cdots}$ clause 18 was not to be construed as extending to conditions ${\cdots}$". In relation to the problems on validity of the goods conformity clauses in FOB contracts, when considering Lord Wright's comments ("${\cdots}$ hence apt and precise words must be used to exclude it: the words guarantee or warranty are not sufficiently clear.") in Cammell Laird & Co Ltd v Manganese Bronze and Brass, FOB contracts are fundamentally one that seller's duty to deliver the goods is completing at the port of shipment and "principle of party autonomy" in Contract Law, I do not think that the terms implied by section 14 of the SGA and Common Law cannot absolutely excluded by the goods conformity clauses in sale contracts. Therefore, in order to exclude the implied terms, the parties must very clearly spell out this in the relevant clauses.

  • Small dense LDL(LDL III) is emerging as a major risk factor for coronary artery disease. LDL III generation is associated with high triglyceride concentration, high hepatic lipase activity, and high cholesterol ester transfer protein (CETP) levels. CETP polymorphisms have been reported to be associated with coronary artery disease. In this study, we investigated the relationship between CETP polymorphism and LDL III generation. VLDL1, VLDL2, IDL and LDL subfractions were measured in 87 normal healthy Korean subjects who had been SNP genotyped for Taq1B, I405v and A629C. We found no differences in LDL subfractions and lipoprotein composition between homozygotes for Taq1B2B2, and those for Taq1B1B1 and Taq1B1B2. There were no differences in LDL subfractions and lipoprotein composition between homozygotes for 629AA, and those for 629AC and -629CC. However, homozygotes for 405VV had a significantly lower LDL III concentration and proportion than those for 405II and 405IV. We concluded that, among the Taq1B, I405V and A629C polymorphisms, only the 1405V polymorphism was associated with the concentration and proportion of LDL III.

  • This article explored the customers protection regulations in electronic payment system by Article 4A of the UCC and EFTA of 1978 and by Electronic Financial Transaction Act of Korea. Both Korea and America have various regulations to protect concerned parties(customers). For examples, the errors of payment order, money-back guarantee, and unauthorized payment order etc. First, this Article focuses on the allocation of risk of loss caused by ambiguous term in payment orders that do not express the subjective intention of the senders. Second, most rights and obligations created by Article 4A of America can be varied with the agreement of affected parties. But there are some exceptions. The exceptions include the money-back guarantee. So Receiving bank have to pay to originator the ordered money included interest. However, Korea also has money-back guarantee but bank do not pay interest to sender. Lastly, Electronic Funds Transfer Act of 1978 and Regulation E has US$ 50 regulation in order to protect customers on the unauthorized payment order. Article 4A imposes duty to detect unauthorized payment orders to originator in relation to the establishment of commercially reasonable security procedure, while Korean law imposes the duty to notify the bank in order to decrease the loss resulted from unauthorized payment order.

  • This research has set up the fire protection and early suppression plan for Asan Oeam folk village which is composed of traditional wooden building instinct or complex. The results of this study are as follows. 1. The traditional wooden buildings require attentive considerations about the fire property of the Waga and the straw roofed house. Especially, as the straw roofed house has property that the transfer and development of the fire is fast. Therefore we studied on the transferring possibilities of the fire dangerous instinct through measuring the distance from of the eaves edge and trees in neighboring house. 2. This research proposes the tools for the priority protective building through consideration of fire risk and cultural priority because the fire prevention for all is impossible at the same time. 3. The most important thing is preserve the cultural identities of traditional folk village in establishing the fire hydrant and fire prevention facilities. Traditional folk village landscape should be considered.

  • This study analyzed President Park's speeches and the government's industry policy in the field of information security using cognitive map. The relationship analysis between policy tool variables and policy goal variables was employed to derive revitalization strategy of information security. This paper found that entrepreneurship revitalization has very strong causality with expansion of domestic market and global market. But, on the other hand, HR development has very weak causality with job creation and future growth driver because the labor market in the information security industry is poor and its transfer rate to other industry is very high. This study showed that this cognitive map could be characterized by a scarcity of feedback loops and a strong emphasis on the positive loops in the structure of virtuous circle. In this paper, we also constructed a comprehensive cognitive map on the policy vision of information security, showing that there are a risk of cyber threat, an opportunity of new fusion security market, information security reinforcing circle, global economic circle, and domestic market circle.

  • There is an increasing appreciation of the vital role that biomechanics play in the performance of oral implant. The aim of this article is to provide some basic principles that will allow a clinician to formulate a biomechanically valid treatment plan. However, at this point in the history of oral implantology, the clinician should realize that we do not know enough to provide absolute biomechanical rules that will guarantee success of all implants in all situations. To examine the biomechanical questions, one must begin with an analysis of the distribution of biting forcess to implants. Related topics, such as stress transfer to surrounding tissues and interrelationships between bone biology and mechanical loading are major subjects, deserving a separate discussion. Once rigid fixation, angulation, crestal bone level, contour, and gingival health are achieved, stress beyond physiologic limits is the primary cause of initial bone loss around implants. The restoring dentist has specific responsibilities to reduce overload to the bone-implant interface. These include proper diagnosis, leading to a treatment plan designed with adequate retention and form, and progressive loading to improve the amount and density of bone and further reduce the risk of stress beyond physiologic limits. The major remaining factor is the development of occlusal concept in harmony with the rest of the stomagnetic system.
