Cognitive Radio 환경에서 서비스영역 밖에 있는 사용자는 통신을 하지 못하도록 규정을 하고 있다. 그 이유는 주사용자가 서비스를 제공받는데 피해나 간섭의 영향을 대비하기 위해서이다. 이와 같은 규정이 보장된다면, CR사용자는 서비스 영역 밖에서도 충분히 서비스를 제공받을 수 있게 된다. 본 논문에서는 주 사용자에게 과도한 간섭을 발생시키지 않는 실용적 시스템에 대한 논의, 즉, 제안된 기법을 통해 부사용자를 위한 가능한 이득이 주사용자에게 비간섭이 되는 사항에 중점을 둔다. 본 논문에서는 그 방법을 BBA(Bi-directional Beamforming Antenna), 즉 지향성 양방향 안테나를 이용하여 제시한다.

Cognitive Radio rules provide that the user outside service region should not utilize communication system in Cognitive Radio environment. The reason why main user should use service without any loss and interference. If this rule is guaranteed, CR users are able to be offered enough services outside service region. In this paper, we target the issue which can operate practical cognitive systems even without causing excessive interference to legacy users. Also, we focus use on non-interference to the primary system rather than realizable benefits for the secondary systems, and using the proposed device. In this paper, we present the possible scheme using Bi-directional Beamforming Antenna.

본 논문에서는 위치인식기반 WPAN에 적용 가능한 무선인지 기술 중에서 BBA 기반의 전력할당기법에 논의한다.. Cognitive Radio 환경을 벗어난 서비스영역 밖에 있는 CR사용자의 관점에서 통신이 가능하게 하는 방법을 찾는 것이 관점이다. CR에서는 서비스 영역 밖에서는 통신을 하지 못하도록 규정을 하고 있다. 그 이유는 주사용자가 서비스를 제공받는데 피해나 간섭의 영향을 최소화하기 위해서이며, 이런 것이 선행되지 않고서는 값비싼 주파수라는 자원을 공유하기를 꺼려 하기 때문이다. 하지만 이와 같은 피해를 주지 않게 보장을 한다면 CR사용자는 서비스 영역 밖에서도 충분히 서비스를 제공받을 수 있게 된다. 그 방법을 BBA(Bi-directional Beamforming Antenna), 즉 지향성 양방향 안테나를 이용하여 가능한 방법을 제시하려 한다.

In this paper, we discuss the BBA based power scaling scheme in cognitive radio technique for WPAN system. We focus on Cognitive Radio environment which is currently ongoing standard procedure and is able to focus on future communication and show the transmitted power scaling of CR user. We suggest the available communication method of CR user, while it is simultaneously satisfying both minimum interference of PU(Primary User) and possible communication of CR user. The method is using the BBA, and we show several merits in face of received SINR. and we prove that CR vary its transmit power while maintaining a guarantee of service to primary users.

Objectives : Through the analyze of formative factor of time sense and the vital movement temporal rhythm in Huang Di Nei Jing(黃帝內經). Methods : We find out the principle and methods of Chronomedicine and Health Preserving in Huang Di Nei Jing(黃帝內經), and this finding will direct the life nurturing for later generations. We find that time sense had been established in Huang Di Nei Jing(黃帝內經), which had yin-yang and five elements characteristic. Results : There have temporal rhythm of functions of zang-fu viscera, meridian and collateral, qi and blood. Based on the theory of correspondence between human body and natural environment, established principle of health maintenance about based on yin and yang, temporal rhythm of visceral qi. Conclusions : Established health maintenance methods based on time such as adjusting-spirit according to time, regular daily life, dietary regimen according to time, needling and moxibustion according to time. These methods will guide syndrome differentiation and therapeutic method and Medication which based on suitable time.

[FeIII(BBA)DBC]ClO4 as a new functional model for catechol dioxygenases has been synthesized, where BBA is a bis(benzimidazolyl-2-methyl)amine and DBC is a 3,5-di-tert-butylcatecholate dianion.The BBA complex has a structuralfeature that iron cent er has a five-coordinate geometry similar to that of catechol dioxygenase-substrate complex.The BBA complex exhibits strong absorptionbands at 560 and 820 nm in CH3CN which are assigned to catecholate to Fe(III) charge transfer transitions. It also exhibits EPR signals at g = 9.3 and 4.3 which are typical values for the high-spin FeIII (S = 5/2) complex with rhombicsymmetry. Interestingly, the BBA complex reacts with O2 within an hour to afford intradiol cleavage (35%) and extradiol cleavage (60%) products. Surprisingly, a green color intermediate is observed during the oxygenation process of the BBA com-plex in CH3CN. This green intermediate shows a broad isotropic EPR signal at g = 2.0. Based on the variable temperature EPR study, this isotropic signalmight be originated from the [Fe(III)-peroxo-catecholate] species havinglow-spin FeIII center, not from the simple organic radical. Consequently,it allows O2 to bind to iron cen-ter forming the Fe(III)-superoxide species that converts to the Fe(III)-peroxide intermediate. These present data can lead us tosuggest that the oxygen activation mechanism take place for the oxidative cleavingcatechols of the five-coordinate model systems for catechol dioxygenases.

硏究趣旨: "黃帝內经太素"是唐初杨上善对"黃帝內经"的內容进行分类整理, 并添加注释编纂而成的书籍. 在编纂"太素"的同时, 杨上善又将当的"黃帝明堂经"中的输穴分为12经脉和奇经八脉, 并对各个输穴的位置和针刺方法, 主治病症等做了详细的注释, 将其编为13卷的"黃帝內经明堂". "太素"和"明堂" 在公元763左右一同传入日本, 此后便成为了日本医生及针针灸敎育的主要教材. 但是"明堂"在9C末除序文和第一卷以外的12卷均遭到遗失, 只剩下了残卷仁和寺永仁本 永德本和尊经阁本. 不过值得庆幸的是, 984年丹波康赖编纂的 "医心方"第2卷关于输穴和针灸的內容中记载了杨上善"明堂"的內容, 因此对"太素"的输穴理论进行硏究时可以参考这本书. 硏究方法: 是从 "太素" 中选取有关输穴的篇章和语句后, 通过将杨上善的注释內容与 "黃帝內经", "难经"和"黃帝內 经 明堂", "医心方"的內容进行对比来加深对"太素" 输穴理论的理解. 然后后将选取的內容分为几大类, 并对各大类的核心语进行了归纳和演绎. 结论: 关于"太素"的输穴理论最后得出了以下几个结论. 1. 所谓输穴有着双重含义, 一是指经脉或脏腑的气经过输送所到达的地方, 另一个是指可以通过实施针灸等治疗方法使疾病痊愈的地方. 在这两个含义中, 杨上善更偏重于治愈疾病这层含义. 2. 脉气所发指的是脉气向经脉的流注路线以及临近部位发散的'气府'的概念. 因此根据位置邻近性原则, 输穴可以是所属完全不同的经脉的脉气所发穴. 对于脉气所发的气府槪念, 杨上善认为它不同于腧穴归经. 脉气所发穴适用于在发病部位的邻近部位近位取穴. 3. 原穴作为向本输输送脏腑原气的场所, 位于四肢的腕踝部位, 是脉动处和诊脉部位, 并且也是直接对脏腑原气进行调节的主要治疗处. 受"难经" 原气说的影响, 杨上善尤其重视本输中的原穴. 他的重视原气和原穴的思想在其对下焦的膀胱脉和部分路线并行的足三焦的说明中也有体现. 4. 对于'心不受邪'杨上善解释说此句是个部分否定句, 其意义不是说心完全不受邪气, 而是说其不太受外邪. 并用这句话对"本输"里没有手少阴心的本输, 而"经脉" 中却记载了心脉的是动所生病, "明堂"中记载了手少阴心的五输穴这一矛盾做出了解释. 5. 颈项部位有好几处输穴是能够观察脏腑气运的诊脉处, "本输"中记载有10处, "寒热杂说"中记载有5处. 这些穴名的特征是大多数都包含一个'天'字, 杨上善将这些输穴中的扶突, 人迎, 天牗, 天柱, 天府称为'五部大输'. 笔者认为这些输穴和本输部位的相应经脉的输穴都曾被看作是人迎寸口脉法等比较脉法的诊脉处, 但是"太素"编纂的当时好像并没有记其记载为比较诊脉处.
