We construct certain ring class fields over an imaginary quadratic field by making use of Shimura's canonical models and extend the result of Chen-Yui ([1] Theorem 3.7.5(2)) to the case where (a, b, N) $\neq$ N or (a/N, N) $\neq$ 1 for a positive integer N > 1.

We in this note study a ring theoretic property which unifies Armendariz and IFP. We call this new concept INFP. We first show that idempotents and nilpotents are connected by the Abelian ring property. Next the structure of INFP rings is studied in relation to several sorts of algebraic systems.

From the study of the definition of and intoxication, detoxication poisonous drug, the symptom and treatment of intoxication, andantidotes with DONG YUI BO GAM etc, it can be concluded as follows. 1. In ancint times, the poisonous drug was a drug which could treat diseases but after that it has been a drug which can injure one's health because it has severe property, poison or side effects 2. Intoxication means that poison goes and works in the body. Detoxication means treatment which clears the symptom of intoxication and removes the toxin in the body or on the body 3. At the intoxication's symptom, vomiting, madness, diarrhea, abdomianl pain, consumption are frequent in order 4. At the intoxication's treatment, vomiting method is used when poison is in the stomach, purgative method is used when poison is the intestine. 5. Mostly Hei-dou is used in drugs and Gan-kao. Qing-yan are used in order. 6. Mostly drugs of reliving fever are used in drugs. 7. Mostly cold drugs are used in drugs and warm, even, hot, cool drugs are used in order and mostly mild drugs are used in drugs and bitter, hot, salty, sore drugs are used in order.

Objective : The aim of this study was to categorize tic disorders and introduce the treatments of tic disorders in oriental medicine. This article includes the report of successful treatment with oriental medicine. Methods : The author classifided the terms of oriental medicine in associated with tic disorders based on DSM-IV and then studied symptoms, etiological causes, and treatment through ${\ll}$Dong yui bo gam Book${\gg}$ . Results and Conclusions : 1. The concept of Tic disorders is similar to Mok-cha (目箚), Gun-chuck-youk-soon, Soon-dong, Mae-hack-gi (梅核氣) and etc, in oriental medical term. 2. In oriental medicine, tic disorders can be classified Gan-poong-nae-dong-zung (肝風內動證) type, Dam-hwa-yo-sin-zung (淡火擾神證) type, Bee-her-gan-wang-zung (脾虛肝旺證) type and Gan-sin-um-her-zung (肝腎陰虛證) type. 3. In oriental medicine, tic disorders are treated by much(so) various therapy such as herb medication, acupuncture and moxibustion, oriental psychotherapy and dirigation (Gi-Gong, 氣功) etc. 4. Tourette’s disorder is not easy to cure. When the treatment of occidental medicine and that of oriental medicine are mutually cooperated, more effective medical care might be expected. Therefore, it is necessary for further study to treat tic disorders by mutually cooperated therapy.

Mobile Ad Hoc Networks(MANET)은 기존의 인프라없이 독립적으로 네트워크를 구성할 수 있는 장점이 있다. 이에 대한 관심의 증대에 따라 새로운 도전 영역으로써 MANET에 인터넷 서비스를 제공하는 인터넷게이트웨이가 등장하고 있는데. MANET boundary를 공유하는 영역에서의 노드는 이러한 여러 개의 인터넷 게이트웨이들에 대한 선택문제가 있게 된다. 이러한 문제점에 대해서 네트워크의 환경에 맞는 적절한 해결책은 아직 미흡한 상태이다. 기존의 해결책은 hop count를 기준으로 간단하게 게이트웨이를 선택하고는 있지만 노드의 이동성에 따른 전송량 감소가 빈번해서 문제점이 있다. 본 논문에서는 MANET이 모바일 환경적 특성을 지니고 있는 점을 고려해서 노드의 이동성향을 고려해서 게이트웨이를 선택하도록 하여 전체네트워크의 전송량을 증가시키는 대안을 제시한다.

Forecasting technology in economic activity is a quite intricate procedure so researchers should grasp the point of the data to use. Diffusion models have been widely used for forecasting market demand and measuring the degree of technology diffusion. However, there is a question that a model, explaining a certain market with goodness of fit, always shows good performance with markets of different conditions. The primary aim of this paper is to explore diffusion models which are frequently used by researchers, and to help readers better understanding on those models. In this study, Logistic, Gompertz and Bass models are used for forecasting Global Wireline Subscribers and the performance of models is measured by Mean Absolute Percentage Error. Logistic model shows better MAPE than the other two. A possible extension of this study may verify which model reflects characteristics of industry better.

Diamod nucleation by mw assisted CVD was examined various conditions namely, (1) diamond nucleation on variour substrate materials, such as Si, cubic BN, pyrolytic BN and AIN, (2) AST(Activated species transport) method which promote nucleation of diamond on single crystal and polycrystalline alumina substrate was developed. (3) Effect of bias enhancement of nucleation on single crystalline Si was examined, and finally (4) DST (Double step treatment) method was developed to enhance diamond nucleation on Ni. In this method, we separated carbon diffusing process into Ni, carbon precipitating process from the inside of Ni and diamond precipitation process.

본 논문에서는 HEMP의 신호 특성을 설명하고 HEMP 방호시설에 영향을 미치는 요소들을 분석한다. 실제 시설 구축에 이용하기 위한 차폐룸의 규격을 정하기 위해 필요한 요소들을 찾는다. 수신 안테나의 거리와 주파수를 변화시켜 차폐 정도를 측정한다. 기준이 되는 미국 규격문서와 측정값을 비교하고 측정방법을 간소화해본다. 차폐룸 내부를 3가지 조건으로 만들어 변화에 따른 차폐 정도를 측정한다. 정방향 측정과 역방향 측정의 차이를 살펴보고 차폐룸 측정에 영향을 미치는 요소를 찾는다.

본 논문에서는 3D 방송의 기본적인 원리를 설명하고 3D 방송을 CS 기술을 적용하여 데이터 용량을 줄이는 방식을 제안한다. 샘플링 이론과 CS 기술의 차이점을 설명하고 개념과 동작원리를 설명한다. 최근 제안된 CS 센싱의 복원 알고리즘인 AMP(Approximate Message Passing)와 CoSaMP(Compressive Sampling Matched Pursuit)를 소개하고 이를 이용하여 이미지 데이터를 압축 복원하여 비교한다. 두 알고리즘의 계산시간을 비교하여 낮은 복잡도를 갖는 알고리즘을 판단한다.
