This study was performed to investigate the cause, symptom, treatment of OPLL through Western medicine and Dong-Eui-Bo-Kham(東醫寶鑑) Results & conclusins 1. Ossification of the posterior hgament(OPLL) have radiculopathy, myelopathy or both of them such as neck pain, numbness, myatonia 2. Neck pain of OPLL seems to be simular with pain in the neck(頸項痛), neck stiffness(項强), stiffness and pain of head and neck(頭項彈痛). The causes were usually Dampness and Cold, Wind. The treatments were classified according to pathoigenic factor(病因) and muscle along the regular meridian(經筋) 3. Radiculopathy of OPLL seems to be similar with numbness(痺證). The causes were usually, pathogenic Wind, Cold, Dampness. The treatments were classified according to diagnosis of three kinds of BI syndrome(三痺), five kind of Bi synrome(五痺), five jang Bi(五臟痺), six Bu Bi(六腑痺) 4. Myelopathy of OPLL seems to be simular with myatonia(痿證) The cause of myatoma was Lung scorched by Heat(肺熱葉無). And the treatment was purping the south and reinforcing the north(寫南方 補北方). We considered that more study to find various and effective methods oriental medicine for OPLL should be made.

In this paper we study the no-wait or no-idle permutation flowshop scheduling problem with an increasing and decreasing series of dominating machines. The objective is to minimize one of the five regular performance criteria, namely, total weighted completion time, maximum lateness, maximum tardiness, number of tardy jobs and makespan. We establish that these five cases are solvable by presenting a polynomial-time solution algorithm for each case.

본 논문에서는 로봇의 목표물 추적을 위하여 SVM을 이용한 12각형 기반의 Q-learning 알고리즘을 제안한다. 제안한 알고리즘의 유효성을 보이기 위해 본 논문에서는 두 대의 로봇과 장애물 그리고 하나의 목표물로 정하고, 각각의 로봇이 숨겨진 목표물을 찾아내는 실험을 가정하여 무작위, DBAM과 AMAB의 융합 모델, 마지막으로는 본 논문에서 제안한 SVM과 12각형 기반의 Q-learning 알고리즘을 이용하여 실험을 수행하고, 이 3가지 방법을 비교하여 본 논문의 유효성을 검증하였다.

This paper is concerned with the long time behavior for the solution semiflow of the coupled two-compartment Gray-Scott equations with the homogeneous Neumann boundary condition on a bounded domain of space dimension $n{\leq}3$. Based on the regularity estimates for the semigroups and the classical existence theorem of global attractors, we prove that the equations possesses a global attractor in $H^k({\Omega})^4$ ($k{\geq}0$) space.

국가 경제규모의 성장과 더불어 하수관거 공사의 규모도, 영세업체들에 의해 소규모 지역별로 시공되던 것에서 벗어나 최근에는 효율적 공사관리와 소요품질의 확보를 위하여 광역화되는 추세에 있다. 광역화의 규모는 2-3개 지자체와 산하의 40-50여개의 마을이 포함될 정도에 이르고 있다. 이러한 하수관거 공사의 규모 확대에 따른 변화에 대응하기 위하여는 적기, 적소에서의 제반 자원의 효율적 활용이 무엇보다 중요한 것으로 분석되었으며 이러한 문제점의 해결방안으로서 IT 기술을 활용한 공사관리시스템을 개발 사용하였다.

Ka Sa Hyeob, who wrote ${\ulcorner}Chea\;Mihn\;Yho\;Sul{\lrcorner}$, lived in the times of Book-Wi (A.D.386-535) and his birthplace was San-Dong Peninsula. If the Back-Jae dynasty governed San-Dong Peninsula during A.D. 285-500, Jeo(Kimchi) of ${\ulcorner}Chea\;Mihn\;Yho\;Sul{\lrcorner}$ should be investigated as Back-Jae's Kimchi, beause it accorded with Ka Sa Hyeob's time of existence.

Anxiety has been suggested to be related to many neurotransmitters in brain, such as norepinephrine, serotonin, dopamine, cholecystokinin, and gamma-amino butyric acid. There are many studies to examine the relationship between anxiety and norepinephrine, and norepinephrine seems to be clearly related to the development of anxiety. We suggest that future studies to explore the pathophysiology of anxiety should be necessary, which include studies on antianxiety drugs, genetic studies, animal model studies, and brain imaging studies.

Carbonucleosides has extensively been studied as a promising anti-viral agents having chemical and metabolical stability. As yet there are no rules relating the structures of carbocyclic nucleosides to their therapeutic activity. although trends among certain kinds of structure have been tentatively put forward. In our research program for discovery of anti-viral drugs, the novel cyclobutyl nucleosides can be expected to be potential antiviral drugs as analogues of cyclobut-A, anti-HBV agent. (omitted)

The pyrolysis of mesaconitine and hypaconitine which are present as strongly toxic components in the raw aconite roots was performed. C(15)-keto pyro type compounds 1, 4 were obtained by the pyrolysis of mesaconitine and hypaconitine, respectively and structures of those compounds were determined as 16-Epi-pyromesaconitine(1) and 16-Epi-pyrohypaconitine (4) having $C(16)-{\alpha}-OCH_3$ on the basis of their spectral and chemical data.
