  • The flow angle at the inlet and exit of a rotor or stator is an important design parameter involved in the design a fan blade. Flow angles along the radial direction for 3-D stacking are calculated using two kinds of vortex methods, i.e. free vortex method and forced vortex method. The performance test shows that a fan designed by the free vortex method is more efficient than a fan designed by the forced vortex method. As a reference, an imported fan is tested. Even though the straightner of the imported fan is used for the comparison test, the difference of efficiency between the imported fan and the fan designed by the free vortex method is negligible. The noise of the fan designed by the free vortex method is less than that of the imported fan. A bellmouth installed at the fan inlet improved the fan efficiency more than $10\%$.

  • We have identified an iridovirus CH-1 from sea perch Lateolabrax sp. healthy externally and imported from China to Korea. In a comparison of the nucleotide sequences of the five different genomic regions, the CH-1 appears to be closely related to the ISKNV, IVS-1 and Ehime-1 strains detected in China, Korea and Japan respectively. In quantitative comparison of the viral DNA, level of CH-1 in tissue of imported fish was 10,000 times lower than that of IVS-1 strain presented in the infected rock bream Oplegnathus fasciatus of moribund stage. It allowed us to speculate the possibility of the asymtomatic iridovirus infection in the culturing sea perch. Such possibility of asymptomatic infection was supported by result of no appearance of dead fish with typical symptoms of iridoviral disease in keeping experiment of the imported sea pearch in laboratory for more than three weeks. Such asymptomatic infections with iridovirus were also found in spleen of the culturing and externally healthy sea perch of Korea by the presence of the iridoviral DNA in nested PCR.

  • As endemic malaria is not commonly seen in the United States, most of the cases diagnosed and reported are associated with travel to and from the endemic places of malaria. As the number of imported cases of malaria has been increasing since 1973, it is important to look into these cases to study the morbidity and mortality associated with this disease in the United States. In this study, we would like to share our experience in diagnosing and treating these patients at our institution. We did a retrospective chart review of 37 cases with a documented history of imported malaria from 1998 to 2012. Among them, 16 patients had complicated malaria during that study period, with a mean length of hospital stay of 3.5 days. Most common place of travel was Africa, and chemoprophylaxis was taken by only 11% of patients. Travel history plays a critical role in suspecting the diagnosis and in initiating prompt treatment.

  • The rapid evolution of antibiotic resistance in Staphylococcus (S.) aureus is of considerable concern. Methicillin-resistant S. aureus (MRSA) strains are especially one of the greatest public concerns since the treatment of infections is more difficult when encountering resistance. In this study, we conducted a nationwide survey on the antimicrobial resistance of S. aureus isolated from raw meat samples collected from 16 countries, including Korea, and investigated the prevalence of MRSA as a possible source of human infection. Of 1,984 meat samples, S. aureus was isolated from 218 (11.0%) samples consisting of 23 (12.1%) from domestic meat and 195 (10.9%) from imported meat. The isolation rates of poultry meat, pork and beef were 12.8%, 7.0% and 10.0%, respectively. With regard to imported meat, the incidence varied from 4.8% to 16.6% from 13 countries, with the exception of Austria and Poland. In a resistance test to 20 antimicrobial agents, one hundred and eighty-four isolates (84.4%) were resistant to one or more antimicrobial agents tested. Especially, 17 (7.8%), 124 (56.9%) and 28 (12.8%) isolates showed a resistance to 3, 2 and 1 drugs, respectively. One isolate originating from domestic beef was resistant to 7 drugs. Another isolate originating from imported poultry meat showed resistance to oxacillin and methicillin by the disk diffusion test and minimal inhibition concentration methods, but showed negative for detection of the mecA gene.

  • This study explored the concept and use of two kinds of textiles goods (Cheongpo [blue textile] and Samseung) sold by Cheongpo-jeon merchants in the Joseon Dynasty of Korea. Research was conducted based on an analysis of relevant documents published during the Joseon Dynasty. The Cheongpo-jeon was a merchant group that predated 1637. They sold various imported goods such as Cheongpo, Samseung, cotton textiles, felts, hats, incense, and needles. Cheongpo and Samseung were the main products among these imported goods. Cheongpo was a blue cotton textile imported from China that was sold by Chengpo-jeon merchants. The Samseung sold by merchants was a kind of imported textile whose surface provided a feeling like cotton flannel. The concept of the two textiles were different from existing ideas. Generally, the Cheongpo was believed to be a hemp fabric dyed in blue and the Samseung was a textile with a density of three seung (a traditional density unit of textiles). Cheongpo was used as a currency for war supplies during the two Japanese invasions of Korea (1592 to 1598). In addition, it was also used to make military uniforms, tents, and flags after the Japanese invasion. Samseung was used in the combat uniforms of Chinese soldiers from Ming China during the Japanese invasion of Korea. In addition, it was continuously used to make quilted gambeson amour and some of military uniforms until the $19^{th}$ century.

  • The objective of this paper is to examine whether it is feasible to introduce an crude oil futures contract on domestic commodity exchange in order to minimize the price risks of imported crude oil. In addition. this study suggests the policy issues to promote futures trading and the alternatives to use foreign energy compares the five criteria to evaluate the feasibility of crude oil futures trading on the domestic exchange. Related to the possibility of successful futures trading of imported crude oil on the domestic exchange, they are evaluated as follows: it is highly possible to succeed for the aspects of price volatility, potential market size or liquidity, and commodity homogeneity; but it is inappropriate for the aspects of deliverable amounts and market power or market structure. Therefore, it is concluded that trading a new futures contract for the underlying imported crude oil on the domestic exchange is inappropriate. For the policy issues and the hedging alternatives, first, it is urgent to establish an atmosphere for futures trading by promoting spot trading. Second, for the case of futures trading on the domestic exchange it is important to consider the simultaneous hedging of crude oil price and foreign exchange risks and mutual offsetting mechanism with major foreign exchanges. Third, for the case of futures trading on foreign exchanges it is reasonable to regard cooperation among concerned companies, government support for futures trading and direct participation into futures trading by the government.

  • A sruvey was conducted to investigate the consumer perception of farm products and processed foods, and to figure out the future direction of food supply system to satisfy the consumer need. From the citizens in Taegu area, 532 housewives were selected as sample subjects by stratified random sam-pling procedure. The main criteria of consumers for purchasing farm products was quality and the main reason for purchasing imported products was cheap price(48.9%). Most of consumers(87%) thought that food safety of farm products was not belong to safe level. Consumers(79.7%) perceived that the labeling system for the place of origin and for the quality are necessary, but they did not have confidence in the current label. Nearly all the subjects(93.6%) were concerned about the hazardness of residual chemicals of imported products, desired the rigorous inspection system for imported products. Consumers in Taegu area had confidence in processed foods in the following order; farmerbrand-product(0.9%), government-authorized farm product(30.0%) and agricultural cooperative association product(26.4%). However, only 73.6% of the consumers had the experience to purchase farmers' processed foods. As a conclusion, it appeared that nutrition education for consumers on food-decision making is strongly required for the substantial segment of population who are still ignorant of safety of imported product and food distribution system.
