The trigeminal neuralgia whose pain is led repeatedly and fitfully is limited inside the trigeminal nervous territory. The cause reveals so far clearly from the western medicine. According to this cause, the treatment is divided into surgical and non-surgical method. But the reduction of pain is not certificate and the case which concurs a sequela is many. So we made up to control typical primary trigeminal neuralgia by oriental medicine treatment like Herb Medication and A-Tx. In this case, patient is diagnosed 'Fire from stagnation of liver and stomach'(肝胃實熱)based on several symptoms. According to this, we used herbal medicine-chungpyesagantang-, and these efforts helped the case of disease.

Let { $A_{>o}$ t= exp(M log t)} $_{t}$ be a dilation group where M is a real n$\times$n matrix whose eigenvalues has strictly positive real part, and let $\rho$be an $A_{t}$ -homogeneous distance function defined on ( $R^{n}$ ). Suppose that K is a function defined on ( $R^{n}$ ) such that /K(x)/$\leq$ (No Abstract.see full/text) for a decreasing function defined on (t) on R+ satisfying where wo(x)=│log│log (x)ll. For f$\in$ $L_{1}$ ( $R^{n}$ ), define f(x)=sup t>0 Kt*f(x)=t-v K(Al/tx) and v is the trace of M. Then we show that \ulcorner is a bounded operator of $L_{-{1}( $R^{n}$ ) into $L^1$,$\infty$( $R^{n}$).

A $C_0$-semigroup ${\tau}=(T_t)_{t{\geq}0}$ on a Banach space X is called subspace-supercyclic for a subspace M, if $\mathbb{C}Orb({\tau},x){\bigcap}M=\{{\lambda}T_tx\;:\;{\lambda}{\in}\mathbb{C},\;t{\geq}0\}{\bigcap}M$ is dense in M for a vector $x{\in}M$. In this paper we characterize the notion of subspace-supercyclic $C_0$-semigroup. At the same time, we also provide a subspace-supercyclicity criterion $C_0$-semigroup and offer two equivalent conditions of this criterion.

본 논문에서는 비콘이 송출한 블루투스 신호의 RSSI를 이용한 근거리 측도에서, 어떠한 조건에서 상대적으로 안정적인 양상의 거리 측도가 이뤄질 수 있는지 분석하였다. 실험 결과, 비콘 신호 송출 각도 조건이 수직 배치일 때와 Tx-Power 조건이 3.5m일 때 실제 거리와 측정 거리가 근접하고, 상대적으로 안정한 양상의 거리 측도가 이뤄졌음을 확인하였다. 본 실험 결과를 바탕으로 근거리 측도가 필요한 서비스에 적용할 수 있으며, 고정 계측 최적조건을 이용하여 향후 동적 계측 연구에 활용할 수 있다.

The stability constant for the complex of $UO_2^{2+}$ with a macrocyclic aminoether ligand, 1,7,10,16-tetraoxa-4,13-diazacyclooctadecane, has determined in aqueous solution. The conductivity and pH metric measurements suggest that the ligand forms a stable 1:1 complex with $UO_2^{2+}$ ion, and the complex is an ionic form, $UO_2L^{2+}$, in aqueous solution. The fact that the ligand does not form a complex with lanthanides, such as $Ce^{3+}$, $Sm^{3+}$, and $Nd^{3+}$ ions, in aqueous solution suggests a possibility of separation of the lanthanide elements from uranium matrix using the macrocyclic aminoether ligand.

The Bluetooth Low Energy profile has the advantage of continuing wireless communication with very little power consumption compared to the existing Bluetooth, so it is widely applied to smart devices. Most of them are applied to Point-to-Point (1:1) communication between Central (Master) and Peripheral (Slave), but can be applied to Point-to-Multiple (1:N) wireless communication through the use of multiple threads and timers. Therefore, in this paper, a precise timer was designed in the BLE profile to devise an image segmentation transmission/reception structure based on multiple access, and a smart image block device applied to it was designed and verified.

Business transactional process is usually long running computation which requests services from multiple enterprises. Web Services Transaction specification (WS-TX) defines a protocol, WS-BusinessActivity which is specifically designed for such lengthy interaction and maintains overall consistency through compensation. However timely web services transaction is prone to compensate due to tasks' missing deadline. Therefore, this paper proposes a reservation-based protocol which is used to select providers who can provide resources promptly and deselect ones who may fail. And this selection happens during resource reservation phase and before real commitment. In this way, we achieve the goal of minimizing transactions' compensation. Finally, we design the framework architecture for the proposed protocol that is extended from WS-BusinessActivity.

스트리밍 XML 데이터는 고정된 저장소에 유지되지 않고 사용자 측으로 계속적으로 데이터가 전송된다는 특성을 지닌다. 이러한 스트리밍 XML에 대한 질의 처리를 위해서는 효과적인 메모리 관리와 빠른 질의 처리 성능이 요구된다. 최근 최소한의 메모리 사용으로 효과적으로 트윅 질의를 처리하기 위한 기법인 StreamTX가 제안되었으나 반복적인 질의 처리 알고리즘 호출로 인해 불필요한 질의 처리시간이 발생한다. 따라서, 본 논문에서는 이러한 불필요한 질의 처리 시간을 줄이기 위해 실시간으로 질의와 무관한 노드를 제거하여 보다 효과적인 질의 처리를 수행 기법을 제안한다. 제안된 기법은 기존 연구와 유사한 메모리 사용량을 가지면서도 빠른 질의 처리 속도를 가짐을 성능평가를 통해 검증한다.

Effective cost management requires reliable cost estimates at every stage of project development. The primary purpose of this research is to develop systematic modeling procedures and an automatic computing program for infrastructure estimating in the Texas Department of Transportation (TxDOT). The computing system toggles between project input information and segregated district unit prices for highway work item quantity estimates associated with earthwork and landscape, subgrade treatments and base, surface courses and pavement, structures, miscellaneous construction, and lighting, signing, markings and signals. This quantity-based approach was chosen because of the conventional approach lacking of quantity information until primary design is complete.

In this paper, we study the following extended generalized variational inequality problem, introduced by Noor (for short, EGVI) : Given a closed convex subset K in q-uniformly smooth Banach space B, three nonlinear mappings T : $K\;{\rightarrow}\;B^*$, g : $K\;{\rightarrow}\;K$, h : $K\;{\rightarrow}\;K$ and a vector ${\xi}\;{\in}\;B^*$, find $x\;{\in}\;K$, $h(x)\;{\in}\;K$ such that $\xi$, g(y)-h(x)> $\geq$ 0, for all $y\;{\in}\;K$, $g(y)\;{\in}\;K$. [see [2]: M. Aslam Noor, Extended general variational inequalities, Appl. Math. Lett. 22 (2009) 182-186.] By using sunny nonexpansive retraction $Q_K$ and the well-known Banach's fixed point principle, we prove existence results for solutions of (EGVI). Our results extend some recent results from the literature.
