Index adjusted ration method has been widely utilized in public construction secter for contract sum adjustment by price fluctuation. In this method. the Production Price Index are used for calculating the base ratio. but the PPI can't reflect the property of construction project in respect of the selected item and weight structure. In this research we prove the problem of using the index adjusted ration method in contract sum adjustment by price fluctuation. and improve it by using the construction cost index. which has the property of construction project. And the result. we figure out the difference between the PPI and CCI by $6.7\%$ in maximum value.

직접 확산 부호 분할 다원 접속 (Direct Sequence Code Division Multiple Access : DS-CDMA) 시스템과 시분할 다원 접속 (Time Division Multiple Access : TDMA) 시스템을 동일 주파수 대역에서 중첩되어 전송할 때 DS-CDMA 신호에서의 TDMA 신호의 협대역 간섭이 문제된다. 본 논문에서는 DS-CDMA 신호의 협대역 간섭(narrowband interference : NI)를 제거하는 방법으로서 노치필터를 이용해서 협대역 간섭파 제거법을 제안하고, 간섭제거기(CCI canceller)를 이용해서 다중접속간섭을 제거하여 DS-CDMA 신호의 성능을 개선한다. 본 논문은 잡음, 다중접속 간섭 및 협대역 간섭환경에서 DS-CDMA 신호와 TDMA 신호의 주파수 공용 시스템에 적용할 때의 성능을 분석하였다.

With increasing competition of the radio spectrum, co-channel interference(CCI) is becoming the dominant interference and may seriously degrade the communication performance of wireless stations. Co-channel interference, when not minimized, increases the probability of packet collisions which cause diminished system capacity. The work presented in this paper investigates the effect of co-channel interference, which is studied in a co-channel interference scenario. To minimize the co-channel interference, a new MAC protocol is proposed in this paper.

This study was performed to estimate the clinical signs and biochemical para meters of indicator on acute hepatic injury induced by the administration of CCl$_{4}$ in rats. Minor behavioral changer brittleness of skin hair and decreased volume of water and food intake were observed in rats after 2 hours of $CCl_{4}$ administration compared to control group. Concentration of serum albumin has shown lower than that of control group. However concentration of total bilirubin has shown higher than that of control group. As times go onto serum LDH activity was significantly increased compared to control Broup. Serum CPK activity hasn't shown change compared to control group. Passive hemagglutination that of afetoprotein was shown negative reaction in all the treatment groups and control group.

The very complicated proplem in spatial processing is effects of phading (Multipath and Delay Spread) and co-channel interference (CCI). The phading is one of principal causes, that form inter-symbol interference (ISI). Spatial-Temproral Adaptive Filter (STAF) has been taken as a solution of this problem, because it can suppress both these types of interference. But the performance of STAF exposes some elemental limitations, in which are the slow convergence of adaptive process and computational complexity. The cause of this is that, STAF must treat a large quantity of information in both space and time. The way that master these limitation is a use of Subband Spatial-Temproral Adaptive Filter (SSTAF). SSTAF reduce computational complexity by pruning off samples of signal and thus it lost some information in time. This draw on attennation of output SINR of SSTAF. The article analyse a optimal solution of this problem by introducing SSTAF with nonuniform weighted distribution.

We propose the dynamic channel allocation (DCA) algorithm for multi-cell OFDMA systems to avoid co-channel interference (CCI). The proposed algorithm is utilized not in a centralized, but in a distributed manner which reduces complexity. The simulation results confirm that the number of overlapping allocated subcarriers is reduced and the average SINR of a sub-carrier is increased by this algorithm.

Nerve injury can lead to neuropathic pain, which is often resistant to current analgesics and interventional therapeutic methods. Extracellular signal-regulated kinase (ERK) plays important role in the induction of neuropathic pain. We explored the antinociceptive effect of curcumin and its effect on ERK in the spinal cord in the neuropathic pain model of rats induced by chronic constriction injury (CCI) of the sciatic nerve. In injured rats, mechanical allodynia, which is one of characteristics of neuropathic pain developed and the activation of ERK in spinal cord significantly increased compared with control group. However, administration of curcumin (50 mg/kg/day p.o) for 7 days started from one day before the injury prevented the development of mechanical allodynia and increase of ERK phosphorylation. These results indicate that curcumin can be a new therapeutic agent in the treatment of neuropathic pain.

Cyperus rotundus L. (Cyperaceae) has been used as an analgesic and antiiflammatory agent and in the treatment of menstrual disorder in folk remedies. Cyperi Rhizomata, processed and unprocessed, were extracted with methanol and fractionated with petroleum ether, chloroform. Butanol, water. The effect of unprocessed Cyperi Rhizoma and processed Cyperi Rhizoma on $CCl_4$ induced lipid peroxidation and hepatotoxity have been tested in rats. BuOH. Water fractions of unprocessed Cyperi Rhizome enhanced the inhibition of antilipid peroxidative effects in liver lipid. In chemical parameters obtained from serum analysis. Butanol fraction of unprocessed Cyperi Rhizoma showed significant decrease in hepatotoxicity. In result, unprocessed Cyperi rhizoma has significant antilipid peroxidative effect and hepatoprotective activity.

Several studies made for wireless mesh networks aim to optimize the capacity for wireless networks. Aside from protocol improvements, researches were also done on the physical layer particularly on modulation techniques and antenna efficiency schemes. This paper is concerned with the capacity improvements derived from using spatial diversity with smart adaptive array antennas. The use of spatial diversity, which has been widely proposed for use in cellular networks in order to lessen frequency re-use, can be used in mesh networks both to minimize co-channel interference (CCI) and enable multiple transmissions. This paper aims to study the capacity region and bounds in using smart antennas for single-channel multi-radio systems in relation to the number of spatial diversity or sectors as defined by the beam angle $\beta$.
