  • The requirement of planarity, such as with-in-wafer nonuniformity, post thickness range, have become increasingly stringent as critical dimensions of devices are decreased and a better control of a planarity become important. The key factors influencing the planarity capability of the CMP process have been well understood through numerous related experiments. These usually include parameters such as process pressures, relative velocities, slurry temperature, polishing pad materials and polishing head structure. Many study have been done about polishing pad and its groove structure because it's considered as one of the key factors which can decide wafer uniformity directly. But, not many study have been done about polisher head structure, especially about polisher head plate design. The purpose of this paper is to know how the plate structure can affect wafer uniformity and how to deteriorate wafer yield. Furthermore, we studied several new designed plate to improve wafer uniformity and also improve wafer yield.

  • Objectives : Spurling test is one of the most widely used physical tests to diagnose herniated cervical intervertebral disc. The purpose of this study is to analyse diagnostic validity of Spurling test. Methods : This study was carried out on 382 subjects who visited Bu-Chun Ja-Seng oriental hospital with the neck pain or radiating pain from neck to upper extremities from November, 2007 to October, 2008. All subjects underwent both Spurling test and cervical magnetic resonance imaging(MRI). The associations between Spurling test and herniated cervical intervertebral disc were analysed. Results : 1. The sensitivity of Spurling test for herniated cervical intervertebral disc was 64%. 2. The specificity of Spurling test for herniated cervical intervertebral disc was 86%. 3. The positive predictive value of Spurling test for herniated cervical intervertebral disc was 93%. 4. The negative predictive value of Spurling test for herniated cervical intervertebral disc was 44%. Conclusions : This study suggests that Spurling test is not useful in screening for herniated cervical intervertebral disc due to the test's relatively low sensitivity. Thus it is necessary to consult advanced tests such as diagnostic imaging to diagnose herniated cervical intervertebral disc.

  • In order to evaluate the improvement effects of head of Panax ginseng on chronic arthritis, we have investigated the activity of butanol fraction (BuOH fraction) in vitro and in vivo system. BuOH fraction showed significant inhibition on the elastase activity. Anti-arthritic activity of BuOH fraction was also examined on type II collagen-induced arthritis in DBA/1J mice. Mice were immunized with injection of type II collagen emulsified in Freund's complete adjuvant, followed by a booster injection 21 days later. BuOH fraction(BHPG) was administered at an oral dose of 500mg/kg for 2 weeks from the 1st day boost. The hind paw edema was significantly decreased in the group of treatment with BuOH fraction compared to control. In collagen-induced DBA/1J mice, BuOH fraction did not affected the collagen antibody titer but significantly inhibited the tumor necrosis factoralpha(TNF-${\alpha}$) activity. These results were confirmed with histological evaluation of joint tissues. This study may raise the possibility that the usage of BuOH fraction of head of Panax ginseng as alternative medicine for the relief and prevention of rheumatoid arthritis symptoms.

As well as we tried to observe how CF pharmacopuncture and BU pharmacopuncture effect on the balance of the autonomic nervous system. Methods : We investigated on 40 healthy volunteers consisted of 20 subjects in CF pharmacopuncture group and 20 subjects in BU pharmacopuncture group respectively. We ruled out subjects whose vital sign isn't in normal range, yet they had taken a rest. The study established by a randomized, single-blind clinical trial. CF pharmacopuncture and BU pharmacopuncture was applied on each group. We measured HRV 7 times : baseline measurement and every 5 minutes for 30 minutes after injection. The SPSS 15.0 for Windows was used to analyze the data by the paired t-test(in group) and Independent sample t-test(between the groups). Results 1. After injection of CF pharmacopuncture, SDNN, Ln(TP), Ln(VLF) and Ln(LF) increased significantly, and Complexity, pNN50 decreased significantly. 2. After injection of BU pharmacopuncture, RMSSD, SDSD and HRV-index increased significantly. Conclusions : We suggest that CF pharmacopuncture activate sympathetic nervous system and BU pharmacopuncture tend to activate the autonomic nervous system.

  • The essential operating parameters in virus vaccine production are multiplicity of infection (MOI), harvest time, and infection time. Stimulating agents also can be applied in order to improve vaccine productivity further. We investigated the optimum operating conditions in porcine transmissible gastroenteritis virus (TGEV) vaccine production and the applicability of sodium butyrate (NaBu) as a stimulating agents for the improvement of vaccine productivity. The optimum MOI, infection time, and harvest time for high production of TGEV by swine testicle (ST) cells were found to be 0.0001 pfu/cell, 3 day after cell inoculation, and 24 hpi, respectively. NaBu is known as a histone deacetylase inhibitor that has been widely used for the high expression of recombinant protein using mammalian cells and for the enhancement of virus propagation. So we tried to examine the potential of NaBu as a stimulating agent and to determine the optimum concentration by comparing TGEV titers with different range of NaBu concentration. TGEV titer with 5 mM NaBu was 1.5 times higher than control. Therefore, we concluded that NaBu can be a promising agent for stimulating various vaccine production including TGEV and the optimum NaBu concentration for TGEV production was determined to be 5 mM.
