Gear pump is a device that changes the mechanical energy into hydraulic energy, generate pressure with flow. Excellent precision and processing gear pump is easy to measure facilitates use of involute spur gear. In this paper, in order to evaluate the formability of the gear using the finite element software AFDEX and analyzed the influence on the material, according to the shape of the preform. And than the maximum pressure of the gear housing and torque delivery analysis was performed by using software ANSYS. Such an interpretation based on the results of the experiment were evaluated. Finally, gear pump in the 24ton class of commercial vehicle were producing.

Collimation proximity exposure system that transfers the pattern on wafer or glass exactly using mask and light with appropriate wavelength is core process in semiconductor and liquid display element which used in PDP(Plasma Display Panel), ELD(Electroluminescent Display) and FED(Field Emission Display), etc. Performances of resolution required in precision exposure system are evaluated by resolving power, depth of focus and storage area. The optical design including lamp house has played an important role on the performance of exposure process. In this study, we evaluate the cooling system, concerning on exposure device with mercury lamp among the kernel equipment for the production of LCD(Liquid Crystal Display), to prevent the instability of lighting due to long term accumulation of excessive heating inside the lamp house. The characteristics of three-dimensional flow, pressure and heat distribution with time variable about exposure system are graphically depicted to estimate the cooling systems for a lamp house.

The present study was carried out to investigate the prevalence of brucellosis in Kyungbuk area for the 3 years from 1966 to 1998. Collective milk samples were routinely screened to detect positive farms by using the milk ring test(MRT), and serum agglutination test was performed to detect sero-positive individuals in the MRT positive farms. Attempt were made to isolate the causative organismas from slaughtered sero-positive reactors and some biochemical and polymerase chain reation characters of the isolates were also made to identify the organisms. Seroprevalence to brucellosis in peoples who are close contact with infected dairy herds was also investigated. Brucellosis of dairy cattle was rare before 1997, but has been broken more frequently since early 1998. By the MRT for dairy herds, positive rate was gradually increased every year: 0.6% in 1996, 1.5% in 1997, 3.9% in 1998. Among 262 MRT-positive herds, only 21 herds(8.0%) showed positive brucellosis in serological test. The isolation rates of Brucella sp from tested materials were 51.2% in supramammary glands, 39.5% in milks, and 50.0% in pulmonary lymphnode, respectively. Isolated strain and biotype were Brucella(B) arbortus biotype 1 in 26 heads, and were B suis biotype 1 in 2 heads. Isolated strain and vaccine strain were very similar in their colony morphology and staining. In drug susceptibility, isolated stains(B abortus) and vaccine strain(B abortus RB-51) were sensitive to ampicillin, gentamycin, kanamycin, neomycin, penicillin, streptomycin, and tetracycline, but resistant to erythromycin. In the PCR, field strains reacted to BA and IS711 primers, and vaccine strain reacted to BA, IS711, and RB51 primers. In the plate agglutination test of 96 sera of human contacted with animals, serum antibody titer detected 1:100 in one person, 1:200 in one, and below 1:25 in
