  • Adaptive bang-bang control algorithm has been proposed by the authors to improve peak response reduction of building structures under unexpected large earthquake. At the previous research, control performance of the proposed algorithm was experimentally confirmed by using a I-DOF test structure. As an extended research, performance tests on a multi-DOF model structure have been conducted to prove the usefulness of the adaptive bang-bang control algorithm using a hydraulic AMD. It is confirmed that the proposed adaptive bang-bang algorithm is applicable to suppress the vibration of multi-DOF structures subject to severe external excitations.

  • The DC motor has the strong characteristics in the speed response, the system parameter variations and the external influence and is used as the speed controller with its good starting torque in the distributing industry. However development of the Microprocessor which is for high speed switching program can make better control system. This paper introduce to design of the high-effective DC motor controller that is using Software Bang-Bang Program of Fuzzy algorithm and to verity a PI controller and a Fuzzy controller.

  • Objectives : The purpose of this study is to analysis of the herb medications corresponded with neuropsychiatry of "Bang-Yak-Hap-Pyun". Methods : The herb medications of "Bang-Yak-Hap-Pyun" Sang.Jung.Ha-Tong(上.中.下統) and "Enlargement side prescriptions" (增補方) are selected by comment on the chief virtue including reference word of corresponded with neuropsychiatry. Results and Conclusion : "Bang-Yak-Hap-Pyun" is a book most people who have a background or career in Han Medicine(韓醫學) would pore over. They corresponded with neuropsychiatry among the herb medications of "Bang-Yak-Hap-Pyun" Sang.Jung.Ha-Tong(上.中.下統) are 55 prescriptions that Sang-Tong(上統) is 8 prescriptions, Jung-Tong(中.統) is 23 prescriptions and Ha-Tong(下統) is 24 prescriptions. And the herb medications corresponded with neuropsychiatry of "Enlargement side prescriptions" (增補方) are 40 prescriptions. And then the herb medications corresponded with neuropsychiatry of "Bang-Yak-Hap-Pyun" received much influence from "Dong-Eui-Bo-Gam". Incidentally the herb medications corresponded with neuropsychiatry of "Bang-Yak-Hap-Pyun" Sang.Jung.Ha-Tong showed the high percentage in Neurosis. And the herb medications corresponded with neuropsychiatry of "Enlargement side prescriptions" showed the high percentage in Psychosis. Besides not only put "Enlargement side prescriptions a premium on "Dong-Eui-Bo-Gam", but also made it the herb medications which were recorded on books flowed after "Dong-Eui-Bo-Gam" known. It was entered up books quoted from "Bang-Yak-Hap-Pyun" Sang.Jung.Ha-Tong but the herb medications were that were not succeeded from "Bang-Yak-Hap-Pyun" Sang.Jung.Ha-Tong. Therefore "Enlargement side prescriptions" shows the efforts for supplement of "Bang-Yak-Hap-Pyun" Sang.Jung.Ha-Tong.

  • In order to establish the robust current controller design technique of series wound motor driver system. This paper proposes a method of compensated Bang-Bang current control using a series wound motor driver system under improperly variable load. Real time implementation of compensated Bang-Bang current controller achieved. Concept design strategy of the control and PWM waveform generation algorithms are presented in the paper.

  • To generalize how early-Chosun medical achievements represented by "Hyang Yak Jib Sung Bang" and "Eui Bang Yoo Chui" influenced the publishment of "Dong Eui Bo Gam", and what academic achievements of "Dong Eui Bo Gam" are, I have compared the compositions of "Dong Eui Bo Gam" to two representative medical literature of early-Chosun era and examined the changes in organizations, and I was able to find deep connections among "Dong Eui Bo Gam", "Hyang Yak Jib Sung Bang" and "Eui Bang Yoo Chui".

  • This paper is mainly on the medical comments in ${\ulcorner}$Sanbeon-bang(刪繁方)${\lrcorner}$. Among the medical comments in ${\ulcorner}Sanbeon-bang{\lrcorner}$, the Ojang-noron(五臟勞論) which deals with the Hanyeolheosil(寒熱虛實) of Ojang(五臟) and Yukgeuknon(六極論) which deals with the Hanyeolheosil of 'Geun-Maek-Yuk-Gi-Gol-Jeong(筋脈肉氣骨精)', remain perfectly. By way of these theories, it argues on various types of pathogenic states and syndromes. Related to the Ojang-noron, ${\ulcorner}Sanbeon-bang{\lrcorner}$ suggests a characteristic tonifying method which is 'Exhaustion syndromes should tonify the son organ(勞則補子法)'. It is the supplement of traditional 'Reinforcing the mother organ when treating cases of deficiency(虛則補其母)'. With the Ojang-noron, the comments about 'Samcho(三焦)' remain relatively intact in ${\ulcorner}Sanbeon-bang{\lrcorner}$. The contents are based on ${\ulcorner}$Yeongchu Yeongwisaenghoe(靈樞 營衛生會)${\lrcorner}$, combined the contents of ${\ulcorner}$Nangyeong 31st difficulty(難經 三十一難)${\lrcorner}$ and the meridian line in ${\ulcorner}$Yeongchu Gyeongmaek(靈樞 經脈)${\lrcorner}$. They were quoted untouched in ${\lrcorner}Cheongeumyo-bang{\lrcorner}$ by Son Sa-mak, and became the fundamental structure of Samcho-theory of after ages. Among the medical comments in ${\ulcorner}Sanbeon-bang{\lrcorner}$, there has been much dispute over the problem about 'Chu-Tae-eum(秋太陰), Dong-So-eum(冬少陰)'. This study will pay attention to the connection between Wang Bing's views of ${\ulcorner}Sanbeon-bang{\lrcorner}$ for compilation of ${\ulcorner}Chaju-Hwangje-Naegyeong-Somun{\lrcorner}$ and the original ${\ulcorner}Sanbeon-bang{\lrcorner}$. Judging from this study, Wang Bing may have referred to ${\ulcorner}Sanbeon-bang{\lrcorner}$, ${\ulcorner}Oedaebiyo-bang{\lrcorner}$ or another medical book of similar stock, and from this he may have reconstructed the attribute of Eum-Yang(陰陽) which is related to Pye and Sin. Wang Bing's disciples may have referred to ${\ulcorner}Sanbeon-bang{\lrcorner}$, or with Wang Do, the writer of ${\ulcorner}Oedaebiyo-bang{\lrcorner}$, building up the main medical current in those days.

  • Objective : "HangYak" and "GuGeupBang" were used as a book title in "HangYakGuGeupBang". Therefore we can examine the early years of the medical of HangYak and the medical of first-aid. Methods : We studied the contents and the characteristics of Acupuncture and External treatments which were presented in "HangYakGuGeupBang". We searched the practical meaning of the publishing it too. According to "HangYakGuGeupBang". Results : Acupuncture was performed as a simple external treatment; however moxibustion was used for various symptoms in several ways. In addition, many external treatments such as hot massages, the treatment of bath and dropping lotion in the eyes were introduced in "HangYakGuGeupBang". We believe that these materials were easily gotten around us so people who lived in a poor and remote village without a doctor could apply with ease if they learned these contents. Conclusions : As a result it can say that "HangYakGuGeupBang" was published as a practical book which could be used simply even though people didn't have enough medical knowledge nor examined inside and outside-heat and cold.

  • A digitally-controlled analog-block inevitably undergoes the bang-bang oscillations which may cause a big amplitudes of the glitches if the oscillation occurs at the MSB transition points of a binary counter. The glitch results into the jitter noise for the case of the DLL. In this paper, we devise a new counter code that has the hysteresis in the bit transitions in order to prevent the transitions of the significant counter-bits at the locking state. The maximum clock jitter is simulated to considerably reduce over the voltage-temperature range guaranteed by specifications. The counter is employed to implement the high speed packet-base DRAM and contributes to the maximized valid data-window.
