Avian infectious bronchitis virus(IBV) was propagated in SPF eggs and purified by sucrose density gradient centrifugation in order to prepare the antigen. Several fusions were made between mouse myeloma cells and spleen cells from BALB/c mouse immunized with IBV antigen and two hybridoma clones producing specific monoclonal antibody(MCA) against the IBV were established. The MCAs were classified as IgG type and revealed no neutralizing and hemagglutination inhibition activity. Using the MCA IBV antigen was detected by IFA method in tracheal smears made from chickens infected with IBV during the experimental period of 10 days.

This study analyzes how to support social economic organizations financially -with online donation system. Two methods of online donation system is compared that vouchers contribute to the creation of sound market in damaged area by giving options of selecting service of social economic organization to service beneficiaries while civil fund for these organizations create employment and improve cooperative relationship between givers and receivers through online donation system. It is important for Korean government to improve donation system not only for victim directly but also for social economic organization through voucher and civil fund method of online donation system.

Based on a survey for Haeundae and Jagalchi, representative waterfronts in Busan, this study examined the users' awareness of waterfront employing human's five senses. The results show that 81.5 %(163 respondents) of users in Haeundae responded "They feel sea breeze" whereas 55.8 %(111 respondents) of users in Jagalchi responded "They can eat seafood".

Various computer-based simulation tools such as 3D-CAD and CAE systems are widely used to design automotive body structure at the early phase of design. Designers must search the optimal solution that satisfies a number of performance requirements by using their tools and a trial-and-error approach. In the previous three reports, a set-based design approach has been proposed for achieving design flexibility and robustness while capturing designer's preference, and its effectiveness has been illustrated with a simple side-door impact beam design problem and real vehicle side-door structure design. This report presents the development of integrated 3D-CAD and CAE system, and the applicability of our proposal for obtaining the multi-objective satisfactory design solutions by applying to an automotive front-side frame.

Equine infectious anemia (EIA) is a worldwide infectious disease of horses and other equids. The large serological survey of EIA was performed in Jeju from 2005 through 2011. Using the conventional enzyme-linked immunosorbent assay (cELISA), a total of 10,040 animals (1,329 Jeju Ponies, 8,324 Jeju Pony-Crossbreds and 387 Thoroughbred horses) was tested at the Equine Hospital of Jeju Race Park or Jeju Stud Farm, Korea Racing Authority. This survey found no serological evidence of EIA presence in Jeju. There had been no horse and pony with antibody against EIA since 1985 and no official report on outbreak the disease. Therefore, surveillance conducted found no evidence of EIA activity in Jeju.

Until recently, almost all ETFE film structures that have been erected is the cushion type because there are problems at lower allowable strength under elastic range and viscosity behaviour such as creep and relaxation of ETFE films under long-term stresses. But the number of tension type structures is currently increasing. This paper proposes the stretch fabrication of ETFE film to verify the applicability of ETFE films to tensile membrane structures. First of all, to investigate the possibility of application on tensile membrane structures, the stretch fabrication test is carried out, and it is verified that it is possible to increase the yield strength of the film membrane structures. After simulating the experiment also carries out an analytical investigation, and the effectiveness of the elasto-plastic analysis considering the viscous behavior of the film is investigated. Finally, post-aging tension measurement is conducted at the experimental facilities, and the viscosity behavior resulting from relaxation is investigated with respect to tensile membrane structures.

The polishing pad is important element for polishing characteristic such as material removal rate(MRR) and within wafer non-uniformity(WIWNU) in the chemical mechanical planarization(CMP). The result of the viscoelasticity measurement shows that 1st elastic modulus is increased and 2nd elastic modulus is decreased when the top pad is thickened. The finite element analysis(FEA) was conducted to predict characteristic of polishing behavior according to the pad thickness. The result of polishing experiment was similar with the FEA, and it shows that the 1st elastic modulus affects instantaneous deformation of pad related to MRR. And the 2nd elastic modulus has an effect on WIWNU due to the viscoelasticity deformation of pad.

In this paper, a polishing pad has been analyzed in detail, to understand surface phenomena of polishing process. The polishing pad plays a key role in polishing process and is one of the important layer in polishing process, because it is a reaction layer of polishing[1]. Pad surface physical property is also ruled by pad profile. The profile and roughness of pad is controlled by different types of conditioning tool. Conditioning tool add mechanical force to pad, and make some roughness and profile. Formed pad surface will affect on polishing performance such as RR (Removal Rate) and uniformity in CMP Pad surface condition is changed by conditioning tool and dummy run and is stable at final. And this research, we want to reduce break-in and dummy polishing process by analysis of pad surface and artificial machining to make stable pad surface. The surface treatment or machining enables to control the surface of polishing pad. Therefore, this research intends to verify the effect of the buffing process on pad surface through analysis of the removal rate, friction force and temperature. In this research, urethane polishing pad which is named IC pad(Nitta-Haas Inc.) and has micro pore structure, is studied because, this type of pad is most conventional type.

Purpose: This study was done to develop a new nursing intervention, Meridian Massage, and to investigate its effect on weight in infants and mother-infant interaction. Method: This study was conducted using a quasi experimental non equivalent control group pretest-posttest design. Thirty-one newborn infants from a postpartum Management Center were selected and assigned to two groups, experimental and control. Data were collected from February 1 to September 30, 2004. Infants in the experimental group (16) were given Meridian massage for 15 minutes daily for 6 days and weighed every day at 10 am. Using the Nursing Child Assessment Feeding Scale(1978), mother-infant interaction was determined before the treatment, after 1 week and 1 month after the massage. Results: Infants in the experimental group had a higher average weight than those in the control group and the difference was significant (Z=-2.29, p=.022). For mother-infant interaction, the experimental group had higher scores tHan the control group, and the difference was significant between both the two groups, and the 3 measurement times. Conclusion: The Meridian Massage in this study showed positive weight gain and positive mother-infant interaction. This study shows that meridian massage is an effective nursing intervention in improving infant development.

Purpose: this study was implemented to develop new nursing intervention, Kyongrak massage, and to examine its effect on chronic pain in elderly women. Method: Kyongrak massage is a manipulation massaging on Kyonghyul site, and Duboo, Kyongchoo, Chucksoo, Hajee, Sangjee Kyongrak massages were used in this study. The subjects(11persons) took Kyongrak massage on head, neck, spinal cord, upper extremities and back lower extremities for 25minutes daily during 5days. The dependent variables were subjective health state, paid, blood pressure, pulse and body temperature. This study was carried out, at 10-12 o'clock, from August 7th, to 22th, 2000. Data were analyzed using frequency, percentage, mean, standard deviation, paired t-test by SPSS PC. Results: subjective health state((t=-3.560, p=.005), body temperature(t=-2.557, p=.029) were increased, and pain level(t=7.884, p=0.000), systolic blood pressure(t=2.923, p=.015) were decreased significantly by Kyongrak massage. Conclusions: The above results have informed us that this Kyongrak massage program(Duboo, Kyongchoo, Chucksoo, Hajee, sangjee) for 25minutes is a useful nursing intervention to decrease chronic pain in each life styles.
