Background: There are many evidences that inflammation is an important determinant of the development of atherosclerosis and one of the systemic markers of inflammation, C-reactive protein(CRP), is associated with extent of coronary artery disease and risk of coronary events. We assessed the time response of CRP response after coronary angioplasty and it's influence on the clinical restenosis in angina patients. Materials and Methods: Patients included 36 angina patients undergoing single vessel angioplasty. Levels of CRP were measured before and 12, 24, 48, and 72 hours after angioplasty. Clinical restenosis was assessed at 6 months after procedure. Results: Baseline CRP level was $0.30{\pm}0.01$ mg/dL in stable and $0.46{\pm}0.28$ mg/dL in unstable angina patients(p<0.05). After angioplasty, CRP level was increased with peak at 24 hour and persisted to 72 hours after angioplasty. At 24 hour after angioplasty, the magnitude of CRP change was $0.32{\pm}0.31$ mg/dL in stable and $0.79{\pm}0.73$ mg/dL in unstable angina patient(p<0.05). The change of CRP level was not associated with troponin-T after angioplasty. In unstable angina patients, clinical restenosis was developed in 8% of patients with low baseline CRP levels and in 50% of those with high baseline CRP levels more than 0.6 mg/dL(p<0.05). Conclusion: In unstable angina patients, inflammatory response is more increased than stable angina patients, and increased inflammatory response effects on the restenosis after coronary angioplasty.

This paper proposes a 24-bit floating point multiply and accumulate(MAC) unit that can be used in geometry transformation process in 3D graphics. The MAC unit is composed of floating point multiplier and floating point accumulator. When separate multiplier and accumulator are used, matrix calculation, used in the transformation process, can't use continuous accumulation values. In the proposed MAC unit the accumulator can get continuous input from the multiplier and the calculation time is reduced. The MAC unit uses about 4,300 gates and can be operated at 150 MHz frequency.

Vsing the phosphorylated thylakoid membrane induced by 5-35kLux of light intensities, we investigated the chlorophyll nuorescence quenching of PSII and the phosphorylation of LHCPII i in relation to the chlorophyll-bleaching of Panax ginseng C.A. Meyer. In the Presence of DCMU, both of the fluorescence yield of non-phosphorylated thylakoid and the rate of fluorescence quencing dependent on the Phosphorylation were high p. ginseng more then Glyine max L. And at the high light F intensity (above 25 kLux) the fluorescence quenching rate of p. ginseng compared with that of G. max reached nearly to 2 times. The LHCPII of P. ginseng was composed of 3 major Polypeptides (24.5, 26 and 27kD) and 3 minor polypeptides (24, 25.3 and 28.3kD) in the region of 24-29kD and differed, from G. max in both of the number and quantity of polypeptides. Among these polypeptides, the phosphorylated polypeptide dependent on the light intensity was 24kD in P. ginseng.

The aim of this study was to evaluate on the removal effect of total nitrogen and phosphorus in municipal wastewater with temperature change from 1$0^{\circ}C$ to 24$^{\circ}C$ in CNR(Cilia Nutrient Removal) process. CNR process is the process combining $A^2$/O process with cilium media of H2L company. The removal efficiencies for T-N were found to be 57.9% at 1$0^{\circ}C$ below, 53.7% at 10-2$0^{\circ}C$, 52.2%at 20-24$^{\circ}C$ and 44.4% over 24$^{\circ}C$ respectively. The removal efficiencies for T-P were 53.3% at 1$0^{\circ}C$ below, 59.1% at 10-2$0^{\circ}C$, 72.4% at 20-24$^{\circ}C$ and 50.0% over 24$^{\circ}C$ respectively. The specific nitrification rate (kg NH$_3$-N/kg MLSS.d) of Oxic basin was 0.088 and 0.053 at 1$0^{\circ}C$ below, 0.077 at 10-2$0^{\circ}C$, 0.097 at 20-24$^{\circ}C$ and 0.088 over 24$^{\circ}C$ respectively. The specific denitrification rate (kg NH$_3$-N/kg MLSS.d) in anaerobic and anoxic was 0.013, 0.008 respectively.

A holomorphic function space in the unit disc D satisfying $\int_D|f'(z)|^p(1-|z|^2)^{p-1}dA(z)$<$\infty$ is quite close to $H^p$. The problems on the existence of the radial limits are considered for this space. It is proved that the situation for p > 2 is totally different from the situation for p $\leq$ 2.

The hormonally active vitamin D metabolite, 1,25-dihydroxy vitamin $D_3[1.25-(OH)_2D_3]$ is one of the several humoral factors that may regulate osteoblast differentiation. The purpose of this study was to evaluate the effects of $1,25-(OH)_2D_3$ on the PDL cells. Human PDL cells were prepared from the first premolar tooth extracted for the orthodontic treatment and they were incubated in the environment of $37^{\circ}C,\;5\%\;CO_2\;and\;95\%$ humidity. $[{^3}H]$-thymidine incorporation as a measure of proliferation potential and alkaline phosphatase activity were evaluated at 10nM, 100nM $1,25-(OH)_2D_3$. The observed results were as follows. 1. $1,25-(OH)_2D_3$ was significantly enhanced $[{^3}H]$-thymidine incorporation at 100nM, But did not affect by 10nM. 2. $1,25-(OH)_2D_3$ was significantly increased alkaline phosphatase activity at 1 day and 6 days in a dose-dependent manner.

Let X, Y be vector spaces, and let r be 2 or 4. It is shown that if an odd mapping $f:X{\rightarrow}Y$ satisfies the functional equation $${\hspace{50}}rf(\frac{\sum_{j=1}^{d}\;x_j} {r})+\;{\sum\limits_{\iota(j)=0,1 \atop {\sum_{j=1}^{d}}\;{\iota}(j)=l}}\;rf(\frac{\sum_{j=1}^{d}{(-1)^{\iota(j)}x_j}}{r}) \\({\ddag}){\hspace{160}}=(_{d-1}C_l-_{d-1}C_{l-1}+1)\;{\sum\limits_{j=1}^{d}\;f(x_j)}$$ then the odd mapping $f:X{\rightarrow}Y$ is additive, and we prove the Cauchy-Rassias stability of the functional equation in Banach modules over a unital $C^*$-algebra. As an application, we show that every almost linear bijection $h:{\mathcal{A}}{\rightarrow}{\mathcal{B}}$ of a unital $C^*$-algebra ${\mathcal{A}}$ onto a unital $C^*$-algebra ${\mathcal{B}}$ is a $C^*$-algebra isomorphism when $h(2^nuy)=h(2^nu)h(y)$ for all unitaries $u{\in}{\mathcal{A}}$, all $y{\in}{\mathcal{A}}$, and $n=0,1,2,{\cdots}$.

In this paper, we propose a dual-mode mixer to have multi-band radar signal receiver to be compact. The proposed mixer using a anti-parallel diode is operated as a fundamental mixer or sub-harmonic mixer with respect to a control voltage. A fundamental mixer with a control voltage show a conversion loss of -10 dB, 1dB compression point of 2 dBm at X-band. On the other hand, it is performed as a sub-harmonic mixer with a conversion loss of -10 dB, 1 dB compression point of 2 dBm at K-band.
