In this paper, we investigate the conventional topological interference management (TIM) with proposed network topology such as 8 trigram (8 user networks). The key observation is that optimal symmetric degree of freedom (DoF) can be achieved for 8 user network with different channel coherence times by adaptively selecting the interference alignment scheme via controlling the alignment feasibility of the transmitted signals. However, this yields a very complex problem, for which we use the combination of different schemes such as interference avoidance and repetition coding. In addition to the above schemes, we propose a triangular transmit cooperation (TTC) algorithm for 8 user networks to achieve the optimal symmetric DoF. And We apply the principle of complementarity of 8 trigram to remove the interferences, and correspond the concepts of win-win and conflict to direct and indirect signals of transmit and receive respectively. We find that the principle of complementarity comes out from the trigram of I Ching. That is, we apply the relation of confrontation and coexistence to 8 transmitters and receivers, and get the results of symmetric DoF of 4/3.

Objectives : Contents on the 64 trigrams in major medical texts from early to late Joseon such as the Uibangyuchwi(醫方類聚), Donguibogam(東醫寶鑑), Somundaeyo(素問大要), Gyeokchigo(格致藁) were analyzed to examine their characteristics and historical context. Methods : Related contents in each medical texts were collected, sorted and analyzed for thorough examination. Results : The study of Changes which was widely applied in the field of medicine throughout the Joseon period focused more heavily on each of the trigram patterns, especially in regards to the qi interaction between the upper and lower axis of the body, rather than the various meanings of the ten wings[十翼]. This is a result of the Jing-Qi-Shen perspective of the body and the universe that transcends the Daoist inner cultivation method[內丹術], under which concepts related to qi circulation such as the opening and closing[闔闢] of the Heaven[乾] and the Earth[坤], the interaction between Water[水] and Fire[火] were considered more important. Conclusions : The historical context of the study of medicine and Changes[易] of Korea could be grasped through analysing the 64 trigrams in medical texts of each period in Joseon. Further research with the field of History of Changes studies is much anticipated.

In ancient times, the society was unity of church and state and this social leader took medical treatment, too. As he ruled over a people with a Chinese classic on divination, many oriental doctors have considered that the medicine and a Chinese classic on divination(周易) have same origine, and have used it. The divination of six yinyang-strokes(六爻) must be made up of some established rules, for example, division of fifty sticks(葉蓍法), use of three coins(擲錢法), use of numbering sticks and number of time(時間作卦法). six yinyang-strokes is one trigram. As we divine good or bad luck through investigation of six yinyang-strokes, we can know good or bad luck of patient's diseases and cares. A purpose of divination is called use-spirit(用神), a spirit to weaken use-spirit is called dislike-spirit (忌神), and a spirit to help use-spirit is called pleasure-spirit(喜神). As use-spirit is a state of disease in divination of disease and patient, use-spirit is patient and dislike-spirit is disease. If supports of use-spirit are more than supports of dislike, it's good luck, but if not, it's bad luck. As use-spirit is a prognosis of disease in divination of care, use-spirit is patient, dislike-spirit is a state of disease, and pleasure-spirit are medicine and doctor. we inspect condition of patient with good or bad luck of use-spirit, state of disease with good or bad luck of dislike-spirit, and medicine with good or bad luck of pleasure-spirit. Finally, we take a bird's-eye-view of the balance of them and decide on course of action.
