  • This study is to investigate the utilization of Indoor Proscenium Stage Zone Lighting method in the dancing performance. In other words, it is about how we can utilize the principle of zone lighting in dancing performance, a kind of stage art. Stage lights give lights on the stage. Therefore they play big and important roles in dancing performances. Lightings make big influence on the overall atvosphere and situations of the dancing work but most of dancers do not perceive their importance and furthermore they don't know about the lightings very well. To let them know about stage lightings better, we studied lightings form the perspective of the dancers who face the lightings without great knowledge thresh the articles and literature related general lightings and lighting design, books related to stage lightings and dancing lightings, previous studies and academic articles. The most important part of this study is to understand and utilize the principle of zone lightiing. Zone lighting is generally called as cross lighting, which means single light from the crossed two lights. When looking into the principle of the zone lighting of the Indoor Proscenium Stage, it means 45 degree lighting from both sides of the top form the point of the dancer When more than two lights are used, the angle of the light should be $90^{\circ}$or 120. It is the principle of the lighting technology showing the face and body of the dancers ing three dimension. Applying for the principle of this zone lighting to the dancing performance of Indoor Proscenium Stage, the lighting methods and the usage of the lightings were studied. As shown above, the role of the lighting is very important in dancing configuration. We hope that the perception on the dancing lighting will be changed and studies on the dancing lightings. By understanding and applying more principles of lighting, we will make efforts to make better dancing performance and dancing conporsers and dancers shall make more efforts and studies on lighting for better works. Through such efforts, we can have more experts and professionals In dancing lighting field and they will help us to describe and express the intention of the dancing work better as dancing artists. We hope that there will be better quality performances through more and diversified studies in this field.

  • Objectives : We aimed to analyze the meanings of the energy and fluid metabolism in the Discourse on Viscera and Bowels of Donguisusebowon, and to find the clues for the explanation of the pathology and symptomatology of Taeeumin. Methods : The Discourse on Viscera and Bowels of Donguisusebowon was reviewed and examined for relevant information on the energy and fluid metabolism from the structural and the functional point of view respectively. And, based on the derived meanings of the energy and fluid metabolism, the pathology and symptomatology of Taeeumin were analyzed. Results and Conclusions : 1. The meanings of the energy and fluid metabolism can be explained by the different attributes of the energy and fluid produced from the esophagus and the small intestine, and the different function of exhaling-dispersing and inhaling-concentrating in the different tract of circulation such as Lung affiliation (esophagus, skin, ear and lung) and Liver affiliation (small intestine, flesh, nose and liver). 2. The Exterior disease of Taeeumin starts with the weakness of exhaling-dispersing function at the skin, and leads to the dysfunction of the esophagus and the lung sequently. The dysfunction of the lung aggravates that of the skin and the esophagus. 3. The Interior disease of Taeeumin begins with excess of the inhaling-concentrating functions at the flesh and the small intestine, and leads to the dysfunction of the lung, which induces the dysfunction of exhaling-concentration at the skin and esophagus. And, this disparities between exhaling-dispersing and inhaling-concentrating functions exasperate the problem at the flesh and the small intestine.

  • TV white space (TVWS) is showing promise to become the first widespread practical application of cognitive technology. In fact, regulators worldwide are beginning to allow access to the TV band for secondary users, on the provision that they access the geolocation database. Device-to-device (D2D) can improve the spectrum efficiency, but large-scale D2D communications that underlie TVWS may generate undesirable interference to TV receivers and cause severe mutual interference. In this paper, we use an established geolocation database to investigate the power allocation problem, in order to maximize the total sum throughput of D2D links in TVWS while guaranteeing the quality-of-service (QoS) requirement for both D2D links and TV receivers. Firstly, we formulate an optimization problem based on the system model, which is nonconvex and intractable. Secondly, we use an effective approach to convert the original problem into a series of convex problems and we solve these problems using interior point methods that have polynomial computational complexity. Additionally, we propose an iterative algorithm based on the barrier method to locate the optimal solution. Simulation results show that the proposed algorithm has strong performance with high approximation accuracy for both small and large dimensional problems, and it is superior to both the active set algorithm and genetic algorithm.

  • 1. Objects This paper was written in order to understand the formative process of Soyangin pharmacology. 2. Methods We analysis Soyangin pharmacology through pathology and new prescription in ${\ulcorner}$Gabobon(甲午本)${\lrcorner}$ and ${\ulcorner}$Sinchukbon(辛丑本)${\lrcorner}$ of ${\ulcorner}$Dongyi Suse Bowon${\lrcorner}$. 3. Results and Conclusions New prescription of Soyangin in ${\ulcorner}$Gabobon${\lrcorner}$ is same or similar to that in ${\ulcorner}$Chobonkwon${\lrcorner}$. So we can recognize that almost Soyangin pharmacology of ${\ulcorner}$Gabobon${\lrcorner}$ is made when Dongmu write ${\ulcorner}$Chobonkwon${\lrcorner}$. And the maintenance of Yin-Qi is key point of Soyangin's pharmacology New prescription of Soyangin is made by regular rules in ${\ulcorner}$Sinchukbon${\lrcorner}$. Dongmu say that Hyungkae(荊芥) Bangpung(防風) Kanghwal(羌活) Dokhwal(獨活) is herbs for descending-Yin, and Sukjihwang(熟地黃) Sansuyoo(山茱萸) Bokryung Taeksa(澤瀉) or Saengjihwang(生池黃) Sukgo(石膏) Jimo(知母) is herbs for ascending-Yang And all new prescription except Sukjihwangkosam-tang(熟地黃苦蔘湯) is composed of asneding-Yang and descending-Yin's herbs. New prescription of the exterior disease contained all descending-Yin's herbs and that of the interior disease contained all ascending-Yang's herbs completly. Namely when ${\ulcorner}$Gabobon${\lrcorner}$ was written Soyangin pharmacology is the maintenance of Yin-Qi by selecting prescription of cold character. And when ${\ulcorner}$Sinchukbon${\lrcorner}$ was written, base sprit of Soyangin pharmacology was not changed. Pharmacology was added ascending-Yang and descending-Yin at a time.

  • Objectives: Pulse energy values recorded with an add-pres sure-type pulse apparatus were correlated with Sasang constitutional syndromes in order to match pulse energy values with Sasang prescriptions. Methods: The pulse energy values were measured with Daeyo Pulse Apparatus at the Gwan pulse point of both wrists. Prescriptions were divided into two major categories of interior syndromes or exterior syndromes, and categorized according to major component herbs specific to each of the four Sasang constitutions, and the relationship between the pulse energy and each groups divided by their prescription was studied. Results: About 10% of all people had nonmal pulse energy values. 10% had values over normal range, and $70\sim80%$ had lower values than normal. The normal range of pulse energy was regarded as being between 450 and 700. Conclusions: 1. For patients of the Soeum constitution, prescriptions without Panax ginseng is suitable for patients with high pulse energy, and prescriptions containing Panax ginseng are suitable for patients who have lower pulse energy. 2. All prescriptions for the Soyang constitution containing Rehmannia radix preparata or Comus officinalis are suitable for patients who have lower pulse energy, and prescriptions containing Rehmannia radix or Gypsum fibrosum are applicable to patients with pulse energy values higher than normal. 3. Most prescriptions for the Taeum constitution containing Semen coicis or Semen castaneae are suitable for patients with lower pulse energy, and prescriptions containing Radix puerariae or Radix et rhizoma rhei can be prescribed for patients who have lower pulse energy levels. 4. The Taeyang constitutional prescription Ogapijangcuck-tang is suitable for patients who have higher pulse energy levels and Mihudeungsikjang-tang is better for patients with lower than normal pulse values. As described above, the pulse energy level of each patient can be matched with a specific Sasang constitutional prescription. If this relationship is taken into consideration with other conventional symptoms, it can be helpful in diagnosis, improving efficacy of treatment, and be used as objective evidence.

  • Recently, an iterative algorithm for finding the interior eigenvalues of a definite matrix by CG-type method has been proposed. This method compares to the inverse power method. The given matrices A, and B are assumed to be large and sparse, and SPD( Symmetric Positive Definite) The CG scheme for the optimization of the Rayleigh quotient has been proven a very attractive and promising technique for large sparse eigenproblems for smallest eigenvalue. Also, it is very amenable to parallel computations, like the CG method for the linear systems. A proper choice of the preconditioner significantly improves the convergence of the CG scheme. But for parallel computations we need to find an efficient parallel preconditioner. Our candidates we ILU(0) in the wave-front order, ILU(0) in the multi-coloring order, Point-SSOR(Symmetric Successive Overrelaxation), and Multi-Color Block SSOR preconditioner. Wavefront order is a simple way to increase parallelism in the natural order, and Multi-coloring realizes a parallelism of order(N), where N is the order of the matrix. Another choice is the Multi-Color Block SSOR(Symmetric Successive OverRelaxation) preconditioning. Block SSOR is a symmetric preconditioner which is expected to minimize the interprocessor communication due to the blocking. We implemented the results on the CRAY-T3E with 128 nodes. The MPI (Message Passing Interface) library was adopted for the interprocessor communications. The test problem was drawn from the discretizations of partial differential equations by finite difference methods. The results show that for small number of processors Multi-Color ILU(0) has the best performance, while for large number of processors Multi-Color Block SSOR performs the best.

  • Objectives : The objective of this study is the Basic research for mind and body cure protocol construction through the Sim(心) study at Buddhism Medicine, Constitutional Medicine, and Oriental Medicine. Methods : 1. The Sim(心) in Buddhism is a target of spiritual culture and subjective awareness of An ascetic person in interior psychology. In this research, the Sim(心) has been modified within a concept of Early Buddhism and You-sic in order to have medical logicality. 2. Since the study deep into Sim(心) within Confucianism has various aspects, each Confucian's theory argument or era. We limited the significance of the Sim(心) to be associated with the category of the Sim(心) in Sasang Constitutional Medicine which is a product of practical Confucianism. 3. The criteria of debate for the Sim(心) is based on the "Hwang-je-nae-gyoung", because "Hwang-je-nae-gyoung" is founded to definite the term regarding spirit or mind in Oriental medicine Results : 1. "Hwang-je-nae-gyoung" which came from thought of You-Sic, thought of Taoism, and Early Buddhism becomes the theoretical basis for the Sim(心) in Buddhism Medicine, Sasang Constitutional Medicine, and Oriental Medicine. 2. The Sim(心) in the mind psychology of Buddhism Medicine, Sasang Constitutional Medicine, and Oriental Medicine has active aspects. but the visual thing // There are visual aspects being contrasted with 'Sim(心)' of mind psychology and aspects of activity in Buddhism medicine, Sasang constitutional Medicine and Oriental Medicine; which are 'Hrd', 'Hrdaya', 'four-large' 'five base', 'chin, chest, navel and abdomen', 'head, shoulder, waist and buttocks' consisting 'the body', and the heart and 'four interorgans' from the study of symbolical interorgans). In Buddhism Medicine, Sim(心)'s Epistemology is the most extensively understood fact about 'Sim(心)', and for Sasang Constitutional Medicine and Oriental Medicine. 'Sim(心)' is limited as an 'Element' that comprises the body. 3. The Functional area of the Sim(心) in the Buddhism Medicine, Sasang Constitutional Medicine, Oriental Medicine is composed with 'consciousness(意識)' 'manas-vij_na(末那識)', '_aya-vij_na(阿賴耶識)', 'mind greed(心欲)', 'Li(理)' and 'Sin(神)', about the interpretive area of 'Sim(心)', 'Sin(神)' of Oriental medicine is the most comprehensive concept, and on the side of the depth of 'thinking' and 'consciousness', '_aya-vij_na(阿賴耶識)' from Buddhism Medicine in the key point. 4. The Sim(心) in the Buddhism Medicine, Sasang Constitutional Medicine, has the positive and negative aspects, such as the 'Dukkha(煩惱)' and A merciful heart or Human Sim(心) and Taoism Sim(心).

  • Background and Purpose Through ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$, Dongmu Lee Je-ma supposed the minds of management for Sasang Constitutional Symptoms, which had been accomplished through several steps from his early writings to ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901. His basic minds of treatment for disease had been supposed early in ${\ulcorner}$Gyojapyungseongjam${\lrcorner}$ and ${\ulcorner}$Gyukchigo${\lrcorner}$, and had been completed to the Sasang Constitutional Symptoms and the minds of management for it, from ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lrcorner}$, ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ written in 1894 to ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901. In this paper, I tried to find the minds of treatment of ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$, through classifying and researching the early minds of treatment (presented in ${\ulcorner}$Gyojapyungseongjam${\lrcorner}$, ${\ulcorner}$Gyukchigo${\ulcorner}$, ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lrcorner}$), and the latter minds of treatment (presented in ${\ulcorner}$Dongyi Soose Bowon${\ulcorner}$ written in 1894, ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901) Methods It was researched as bibliologically with his writings such as ${\ulcorner}$Gyojapyungseongjam${\lrcorner}$, ${\ulcorner}$Gyukchigo${\lrcorner}$, ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lrcorner}$, ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ written in 1894, ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901. Results and Conclusions The conclusions were as follows. 1. At early, Dongmu Lee Je-ma pursued the minds of treatment at the autonomous control through 'Acquaintance and Self-control' based on 'the Knowledge of Nature and Desire', so emphasized 'self-control' as important point in treatment. 2. From ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lcorner}$, Dongmu summarized Sasang constitutional symptoms structurally in view of Morpho-imaginary. In ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lcorner}$ and ${\ulcorner}$Dongyi Soose Bowon${\lcorner}$ written in 1894, It was described in view of small organ, but in ${\ulcorner}$Dongyi Soose Bowon${\lcorner}$ published in 1901, suggested more updated in view of both large and small organ and to which added the concept of Hot and Cold. 3. Through reinterpreting the concept of interior and exterior disease in ${\ulcorner}$Sanghanrhon${\lcorner}$, the concept of Sasang constitutional symptoms had started as the minds of treatment for individual disease, but in ${\ulcorner}$Dongyi Soose Bowon${\lcorner}$ published in 1901, it was accomplished as the minds of broad management for Sasang Constitutional Symptoms. 4. In ${\ulcorner}$Dongyi Soose Bowon${\lcorner}$ published in 1901, the broad therapeutic prescriptions for management of Sasang constitutional symptoms were proposed newly, according to the accomplishment of Sasang constitutional symptomatic patterns, so these have different aims and are more important than that proposed previously. 5. The control in view of 'Knowledge and Deed' and the minds of management for Sasang constitutional symptoms are the minds and spirits for treantment and prevention against disease, which can maximize the power of autonomous self-treatment and manage all disease broadly.
