Background: Assessment of the nursing staff knowledge, attitude and practices about cervical cancer screening in a tertiary care teaching institute of rural India. Materials and Methods: A cross sectional, descriptive, interview-based survey was conducted with a pretested questionnaire among 262 staff nurses of a tertiary care teaching and research institute. Results: In this study 77% respondents knew that Pap smear is used for detection of cervical cancer, but less than half knew that Pap smear can detect even precancerous lesions of cervix. Only 23.4% knew human papilloma virus infection as a risk factor. Only 26.7% of the respondents were judged as having adequate knowledge based on scores allotted for questions evaluating knowledge about cervical cancer and screening. Only 17 (7%) of the staff nurses had themselves been screened by Pap smear, while 85% had never taken a Pap smear of a patient. Adequate knowledge of cervical cancer and screening, higher parity and age >30 years were significantly associated with self screening for cervical cancer. Most nurese held a view that Pap test is a doctor procedure, and nearly 90% of nurses had never referred a patient for Pap testing. Conclusions: The majority of nursing staff in rural India may have inadequate knowledge about cervical cancer screening, and their attitude and practices towards cervical cancer screening could not be termed positive.

Recently cases of canine distemper have occurred in Korea despite vaccination was carried out nationwidely. This study was performed to establish rapid diagnosis of canine distemper by RT-PCR, nested PCR, and serological test. A total of 30 dogs, which were suspected canine distemper clinically, was examined. RT-PCR and nested PCR were specific for the amplification of CDV H gene and sensitive to detect 7 TCID50 of Onderstepoort strain. By RT-PCR, H gene was detected in 6(20%) of 30 peripheral bloods from dogs. And H gene was detected in 10(33.3%) of 30 samples by nested PCR. H gene was detected from 1 brain of 6 years-old Beagle dog and 1 lung of 2 months-old Shihtzu dog, in which peripheral blood H gene was not detected. Serum neutralizing antibody titer against Onderstepoort strain ranged from 4 to 1,024 in 30 patients. No correlation was observed between the results of nested PCR and titiers of neutralizing antibody.

Currently, various diseases reside in Korean swine farms and affect production performance of the farms greatly. These damages from disease are further aggravated by the concurrent infection of other disease. In this study, y investigating the distribution of porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV2), Salmonella spp. in farms, correlation between the damage and the prevalence of disease was analyzed. Ten selected Korean swine farms that uses PCV2 vaccine were tested for presence of antibody and antigen of PRRSV, PCV2, Salmonella spp. per ages of pigs, 4weeks, 7weeks, 11weeks and 17weeks, respectively. The results were analyzed by dividing the farms in to groups with MSY above 19, and that with MSY below 19. Then calculating the distribution of disease each ages of pigs. Farms with MSY below 19 showed high prevalence of disease by PRRSV, PCV2 and Salmonella spp.. In this group, the detection rate of PCV2 and Salmonella spp. was increased by the activation/viremia of PRRSV in the young ages of pigs. The results are proved that the correlation between disease prevalence and production performance in Korean swine farms were very significant. The prevalence of PRRSV is more important index which influence to the productivity in current prevalence of diseases.

Due to rapid development of mobile device technologies, the mobile banking through Internet has become a major service of banking information systems as a security-critical information systems. Recently, lots of mobile banking information systems which handle personal and transaction information have been exposed to security threats in vulnerable security control and management processes, mainly software systems. Therefore, in this paper, we propose a process model for software security improvements in mobile banking information system by application of fault tree analysis(FTA) and failure modes and effects analysis(FMEA) on the most important activities such as 'user authentication' and 'access control' and 'virus detection and control' processes which security control and management of mobile banking information systems are very weak.

Viruses in the genus Megalocytivirus have been subdivided into four subgroups. Among these subgroups 2 and 4, represented by the red sea bream iridovirus (RBIV) and the olive flounder iridovirus (FLIV), respectively, are non-exotic. subgroups 1 and 3, represented by the red sea bream iridovirus (RSIV) and the infectious spleen and kidney necrosis virus (ISKNV), respectively, have not been detected in Korea and are known as exotic. Shellfish are filter-feeders, and can thus filter and accumulate Megalocytivirus in their digestive glands, allowing us to track viral contamination in surrounding aquatic environment. In this study, we developed a high-resolution melting (HRM) analysis to differentiate among subgroups of Megalocytivirus accumulated in shellfish, and confirmed the convenience and efficiency of this method. More than two subgroups of Megalocytivirus were found in the digestive gland of a single shellfish. We classified all Megalocytivirus viruses from shellfish in Korea into subgroups 2 and 4, although proportions of subgroups were different among regions. Compared to nucleotide sequencing analysis, HRM analysis is a simple and rapid method for differentiating of Megalocytivirus subgroups.

Human Astrovirus (HuAstV), known as a waterborne virus, is a group IV positive-sense single-stranded RNA that belongs to Astroviridae. The first outbreak of HuAstV was reported in England in 1975. HuAstV can exist not only among clinical patients but also in various water environments, such as water for agriculture and vegetables. For diagnosis of HuAstV from water samples, a polymerase chain reaction (PCR) system has been developed. However, the PCR-based diagnostic method has problems in field application, such as reaction time, sensitivity and specificity. For this reason, in this study we developed the loop-mediated isothermal amplification assay (LAMP) system, aimed specifically at HuAstV. Three prepared LAMP primer sets were tested by specificity, non-specificity and sensitivity; one LAMP primer set was selected with optimum reaction temperature. The developed LAMP primer set reaction conditions were confirmed at 62℃, and detection sensitivity was 1 fg/μL. In addition, restriction enzyme HaeIII (GG/CC) was introduced to confirm that the LAMP reaction was positive. As a result, selected LAMP primer set was 100 - 1000 times more specific, rapid, and sensitive than conventional-nested PCR methods. For verification of the developed LAMP assay, twenty samples of cDNA from groundwater samples were tested. We expect that the developed LAMP assay will be used to diagnose HuAstV from various samples.

To protect information resources, many organizations including private corporate and government employ integrated information security systems which provide the functions of intrusion detection, firewall, and virus vaccine. So, in order to develop a reliable integrated information security system during the development life cycle, the managers in charge of the development of the system must effectively distribute the development resources to the quality factors of an integrated information security system. This study suggests a distribution methodology that minimizes the total cost with satisfying the minimum quality level of an integrated information security system by appropriately assigning development resources to quality factors considered. To achieve this goal, we identify quality factors of an integrated information system and then measure the relative weights among the quality factors using analytic hierarchy process (AHP). The suggested distribution methodology makes it possible to search an optimal solution which minimizes the total cost with satisfying the required quality levels of processes by assigning development resources to quality factors during the development life cycle.

Chimeric fusion proteins involving IgG have proven valuable in studying protein-protein interactions and may possess therapeutic applications as well. For example, three receptor subtypes for the natriuretic peptides, when fused to the Fc portion of human IgG ${\gamma}$ chain, were quantitatively and qualitatively indistinguishable from the native receptor, thus allowing detailed structure-function studies of the receptor. In an attempt to block human immunodeficiency virus infectivity with soluble derivatives of CD4, a CD4/IgG Fc chimeric molecule was shown to increase the plasma half life of soluble CD4 and possessed the added advantage of IgG Fc-mediated placental transfer. In the case of the KGFR, this approach provided a framework for dissection of its ligand binding domains and made it possible to demonstrate that high affinity binding sites for two ligands, aFGF and KGF, reside within different receptor Ig-like domains. Chimeric molecules fused to immunoglobulins would have the advantages of secretion from transfected cells as well as detection and purification from medium utilizing Staphylococcus aureus Protein A. In addition, where highly related receptors make their discrimination very hard due to the difficulties in generating specific immunochemical probes, IgG fusion protein with tailor-made specificities confers particular advantages to elucidate patterns of receptor distribution and expression. The approach described here may have general applications in defining ligand-receptor interactions as well as searching for specific agonists and antagonists of receptor function.

The present study was undertaken to observe the immune status of breeding hens and laying hens against Newcastle disease (ND). The methods of extraction of hemagglutination inhibition (HI) antibody from egg yolk, the detection of HI antibody in egg albumen and the correlation between HI antibody titers in maternal sera and egg yolks were discussed. For the purposes of these experiments, 9 flocks of breeding hens and 16 flocks of laying hens immunized against Newcastle disease virus were investigated. The vaccination program of tested flocks was 3-3-3 or 4-4-4 in general. The results obtained are summerized as follows: Freezing-thawing was the best method far antibody extraction from egg yolk for HI test. The HI antibody against NDV was found in egg albumen (geometric mean, 4.5), but lower than that found in egg yolk (32.1). The geometric mean of HI antibody titers of egg yolks (84.1) was higher than that of maternal sera (68.4) and day-old chicken sera (25.3). There was correlation between HI antibody titers of maternal sera(Y) and those of egg yolks(X). The coefficient correlation was r=0.63, and the line of regression of Y on X was $\hat{Y}$=35.91+0.35X.

A thirty-five week old elk was referred for Chronic Wasting Disease (CWD) confirmation from Chungnam province in Korea. Necropsy revealed much bloody contents in the lumen of small and large intestines, and reddening of its mucosa. Microscopically, few coccidia showing various developmental stages were infiltrated in lamina propria of small intestine with granulomatous inflammation and congestion. They were identified as Eimeria spp. according to their location and morphological characteristics. Because fecal examination and oocyst culture were not available, the species of the Eimeria could not be confirmed. There were no detection of pathogenic bacteria such as clostridia and virus in intestinal contents. CWD was shown to be negative in immunohistochemistry test. In conclusion, it was the first Eimeria case detected in small intestine of Korean domestic elk as far as we know although Eimeria spp. were not the main cause of death.
