Objectives : In oriental medicine, many researchers have studied Myofascial Pain Syndrome and Twelve-Meridian Muscle system in correlation with the orthodox form of muscular anatomy. In this study, the authors compared Myofascial Pain Syndrome with Twelve-Meridian Muscle system and interpreted Myofascial Pain Syndrome through Yook Kyoung theory to reveal the similarity between Myofascial Pain Syndrome and Twelve-Meridian Muscle system, as well as to suggest another useful therapeutics. Methods : The authors investigated several literatures related with Myofascial Pain Syndrome, Twelve-Meridian Muscle system and Yook Kyoung theory. Conclusions : 1. Myofascial Pain Syndrome and Twelve-Meridian Muscle system have many similar features in their theory, concept, physiological function, pathological symptom, therapeutic principal, etc., also have some different features. 2. Myofascial Pain Syndrome is thought to be induced by the unbalance between the upregulated-Kwelum energy and the downregulated-Soyang energy in a viewpoint of Yook Kyoung theory, therefore, it is requisite to control the unbalanced energy between Kwelum and Soyang.

용액공정을 이용하여 우수한 특성을 가지는 OLED를 제작하기 위해서는 다층 박막을 형성하여야 하며, 일반적인 용액공정으로는 다층 구조를 형성하는 데에 어려움이 있어 다양한 공정 및 재료에 대한 연구와 개발이 이루어지고 있다. 박막을 전사하는 방법은 상부막에 사용되는 용매의 침투에 의한 하부막 손상을 최소화할 수 있다는 장점을 가지고 있지만, 사용할 수 있는 전사 공정은 극히 제한적이다. 본 기고에서는 전사 공정으로서 산업에 이용되고 있는 hydrographic printing (수전사) 공정을 OLED 제조에 적용하고 그 가능성에 대하여 알아보고자 한다.

In this paper, we analyzed the signal distortion incorporating meander-shaped transmission line on PCB in broadband frequency range, up to 50GHz. This broadband characteristic provides reasonable analysis of digital pulse having very short rising time. Simulation results reveal suppression characteristic at multiband which is dependent on only the width of meander arm. This width of arm also can be adjusted using different permittivity because it provides different effective wave-length. It is found that the suppression characteristic shows sharpness with as a function of the number of arms. However, these characteristics shown limitation for microstrip line structure rather than for stripline structure, so we can avoid these unwanted phenomena using stripline structure.

A mixed host structure of TCTA and TPBI was used in orange emitting layer and host composition was critical to device performances of PHWOLEDs. PHWOLEDs with TPBI host in orange emitting layer showed high quantum efficiency of 10.3 % at $1000\;cd/m^2$ with little change of CIE coordinates of (0.32, 0.34) from $100\;cd/m^2$ to $10,000\;cd/m^2$.

Ligusticum tenuissimum belongs to Umbelliferae, and its root is generally used in headache, common cold and arthralgia L. We have extracted and isolated butylidene phthal ide, 3-butylidene-4,5-dihydrophthalide of phthalide group and l-limonene, etc. of terpenoid group from the root by ordinary method. In Ligusticum sinense, L. jeholense, L. tenuissimum, L. jeholense var. tenuisectum, and L. officinale etc., the components of cnidilide, ligustilide of phthalide group are common features and specific constituents in genus Ligusticum. Therefore comparing that there is no phthalide group in genus Angelica, we think it is able to classify the difference of genus between Ligusticum and Angelica of Umbelliferae in chemotaxonomy.

A high efficiency deep blue phosphorescent organic light-emitting diode (PHOLED) was developed using a new wide triplet bandgap host material (PPO1) with a phenylcarbazole and a phosphine oxide unit. The wide triplet bandgap host material was synthesized by a phosphornation reaction of 2-bromo-Nphenylcarbazole with chlorodiphenylphosphine. A deep blue emitting phosphorescent dopant, tris((3,5-difluoro-4-cyanophenyl)pyridine)iridium (FCNIr), was doped into the PPO1 host and a high quantum efficiency of 17.1 % and a current efficiency of 19.5 cd/A with a color coordinate of (0.14,0.15) were achieved in the blue PHOLED. The quantum efficiency of the deep blue PHOLED was better than any other quantum efficiency value reported up to now.

High efficiency white organic light emitting diodes were fabricated by using an alignment free mask patterning method. Only red/green emission without any blue emission was observed in the red/green patterned region and blue emission was emitted in other area. A combination of the red/green and blue emission gave a high efficiency white emission. A maximum current efficiency of 30.7 cd/A and a current efficiency of 25.9 cd/A at 1000 cd/$m^2$ were obtained with a color coordinate of (0.38, 0.45).
