Objectives : This research aimed to 1) analyze the true meanings of the chapter, 'Wigi Haeng (Wei Qi Xing), the movement of guard qi' in Youngchu (Ling Shu) from the point of view of ancient Chinese Astronomy, 2) calculate the speed of Wigi over 24 Chinese seasons, 3) analyze the true meaning of daytime and nighttime in the chapter. Methods : 1) The chapter 'Wigi Haeng' was analyzed using concepts of ancient Chinese astronomy, 2) the records of angular distances of 28 constellations in the Book of Han (Han Shu) were used to analyze the meanings, and 3) the records of lengths of daytime and nighttime in the Book of Hou Han (Hou Han Shu) were used to calculate the speed of Wigi. Results : 1) The author of the chapter 'Wigi Haeng' did not consider the irregularity in the angular distances of the 28 Chinese constellations (Su). 2) The commentary in the Huangjenaegyong Taeso (Huang Di Nei Jing Tai Su) about the constellations in the chapter is correct. 3) The speed of Wigi changes in daytime and nighttime depending on the seasons. 4) When the speed of Wigi increases in daytime, the speed in nighttime decreases, and vice versa. 5) The beginning of daytime in 'Wigi Haeng' is not the time of sunrise but the time of dawn (2.5 Gak before sunrise). The nighttime ends 2.5 Gak after sunset. Conclusions : 1) The chapter 'Wigi Haeng' demonstrates the ancient astronomical point of view on the universe and the movement of Wigi. The speed of Wigi is variable. 2) This chapter does not address the irregularity in the angular distances of the 28 Su. 3) More research is needed on the meaning of daytime and nighttime in 'Wigi Haeng'.

We could summerize the concept of the right and left mentioned in Nai-Gyung and some literature of oriental medicine as follow At first the right and left is a directional right and left which implys left-liver-right-lung(左肝右肺), left-yang-right-eum(左陽右陰), secondly it is also the road of eumyang which implys man-left-woman-right(男左女右), left-blood-right-ki(左血右氣), left-sinsu-right-myungmon(左腎水右命門), and left-right of pulse. left-liver-right-lung(左肝右肺), left-yang-right-eum(左陽右陰) and man-left-woman-right(男左女右) are expressions of the movement of yang which is a core of chang, at the same time, left-blood-right-ki(左血右氣), left-sinsu-right-myungmon(左腎水右命門), and left-right of pulse are expressions of the eum in response to the movement of yang. (go up and down of water and fire) Finally, both a directional right and left and a road of eumyang mean a road of going up and down of eumyang so, this is very important index in circulation and keeping ballance of eumyang (ki-Hyul:氣血) in the human body therefore, we can treat a disease with acupuncture in the use of this charater, for example when a disease occurs in the left side, we can treat it with acupuncture in the right side, the same applys to right.

Objectives: The subject of this research is the catechism on medicine between the doctors of Joseon and Japan in the 18th century through Choson Delegation(朝鮮通信使 ). Methods: The author intended to review and analyze the contents of catechism related to Acupuncture and Moxibustion and determined the characteristics of Joseon and Japan ?s Acupuncture and Moxibustion. Results: At the time, Japanese doctors had a grasp on most theories of Acupuncture and Moxibustion and were very specialized clinically. They usually used filiform needles with various techniques, and already they had many different schools in practice. However, they wanted to know if their Acupuncture and Moxibustion skills were up to the international standard, especially to Joseon, whom they regarded as a country advanced in Acupuncture and Moxibustion. They wanted to com- pare and contrast their Acupuncture and Moxibustion with Joseon's. 18th century Joseon was high time for Acupuncture and Moxibustion. Various tools were used in surgery, and varieties of needles were used to stimulate acupuncture points. The development of tools evinces the precision of Joseon's Acupuncture and Moxibustion at the time. Also, comprehensive works such as DongUiBoGam(東醫寶鑑) and UiHaklpMun( 醫學入門) greatly influenced Acupuncture and Moxibustion. Because of this impact, it can be deduced that Acupuncture and Moxibustion emphasizing Jang(臟) and Bu(腑) organs and Internal Injury developed greatly. In addition, acupuncturist Holm(許任)'s fame continued from the 17th century into the 18th century, and his medical practice left a huge mark on not only Joseon but other eastern Asian countries as well. Conclusions: We found out the evidences that there were a lot of exchanges of acupuncture and moxibustion between Korea and Japan based of the Joseon TongShinSa (Emissary)'s record of catechism on medicine in the 18th century.

We have demonstrated a fiber short-wavelength filter with a good cut-off property using dissimilar dispersive properties between? a thermally expanded cored fiber and an external medium. Side-polishing is applied to coupling between the fiber and the external medium. The experimental results revealed that the bend edge wavelength can be adjusted by controlling the degree of core expansion. Futhermore, the sharpness of wavelength response? was significantly? improved by employing expanded core fiber instead of a conventional single mode fiber. Tuning range of the band edge wavelength exceeded 400 m based on thermo-optic effect of the external medium.

Objectives : Balhae was a Kingdom forming the Period of Southern and Northern Kingdoms with shilla. Because there have been paid little attention to the medicine of Balhae in the medical history field, we have little information on the medicine of Balhae thoroughly in detail. The aim of this study was to explorer on the acupuncture and moxibustion in Balhae as a part of the study on the medicine of Balhae. Methods : Because the historical remains of BalHae is not sufficient, it is hard to find out the part directly related to medicine However, the study established the category of acupuncture and moxibustion based on two rational frames from both diachronic and synchronic respects. Results : BalHae succeeded to the unique tradition and manufactured excellent needles which is harmless to human body. And BalHae's acupuncture was the highest level in those days by succeeding to the tradition from Gogugryeo. There might have been the Bi-Bo idea that we can treat country's disease with the Bo-sa (補瀉) theory of acupuncture in BalHae. Conclusions : We could know that there has been many medical scriptures of our own in BalHae, We could find out that BalHae succeeded to the legitimacy of our native medicine from Gojosun to Goguryeo and that they had the highest Acupuncture and Moxibustion in those days.

Objectives : Many researchers in western societies raised questions on methodological limitations of randomized controlled trial (RCT) for studying Complementary and Alternative Medicine (CAM), and they have tried to find alternatives to RCT. Some of them recently have interest in health service research as one of the alternatives. Discussing the significance of health services research in CAM studies will be helpful to guide the researchers in Korea who are also interested in developing an appropriate research methodology for traditional Korean medicine. Methods : Previous studies on methodological issues of studying CAM and health service researches published in western societies until 2009 were searched mainly from Pubmed. The definition, main research domains, and research methods of health service research and the significance of it for researches on CAM were summarized. Results & Conclusions : Health service researches are important in two aspects. First, health service researches evaluate the actual practice of CAM, including the individualized diagnosis as well as treatment and interaction between practitioners and patients. Second, when evaluating the outcomes, they put an emphasis on subjective evaluation by patients as well as objective evaluation by doctors. Thus, it can reflect the treatment goals of CAM which is improving the overall quality of life and the physical and psychological health. Therefore, health services researches such as descriptive studies, qualitative studies, outcomes studies including economic evaluation, and whole systemic research should be more utilized in order for studying traditional Korean medicine.

In this study, we have fabricated a gain flattened erbium-doped optical fiber amplifier. Gain flattening filters were realized by the strain-induced long period fiber gratings, which are made of periodically arrayed metal wires. Using the filter of $550{\mu}m$ period, spontaneous emission amplified at C-band wavelength by a 980nm pumping laser was flattened within 1dB of gain ripple. The performance of the simultaneous multi channel amplification was measured using a fabry-perot laser diode. Amplification ratio was above 20dB. This amplifier can be applied to the long distance transmission system based on a wavelength division multiplexing for boosting an attenuated signal.

Objectives : The purpose of this study is to discuss the diagnostic classification of the traditional medicine for pilosis, and the hair removal treatments in traditional medicine and its clinical application. Backgrounds : In recent years, appearance and beauty have become main interest that have positioned in the medical area. In clinical Korean medicine, a variety of methods such as moxibustion, superficial bleeding, multiple microneedling, facial meridian massage, herbal medicine facial pack, laser acupuncture, and intense pulsed light (IPL) have been applied. Methods and Results : Pilosis, a condition of abnormal hair growth, is stated for the first time in the publication, [Pathogenesis and Manifestations of All Diseases] by Chao Yuan-fang in 610 A.D. It shows that pilosis has been recognised as a disease for ages in Asia. Reviewing several publications, we found multiple approaches to pilosis were already existed in korean medicine. They include internal medicinal classification and its' medications. Acupuncture treatments also focused on regulation of radical causes and superficial removal of abnormal hairs. Specific treatments includes body and ear acupuncture, ear acupressure, hypodermic acupuncture, hypodermic acupuncture injection, laser acupuncture treatment. Physical and chemical methods of hair removal were widely invented. we resulted that significant scientific approaches to pilosis are under way in the korean medical field, and found a variety of medical treatments such as herbal medicines and dermatological methods. Conclusions : Hair removal treatments for pilosis in traditional medicine has a long history. Combined with advanced modern technology it can achieve greater advance in cosmetology.

In this paper, we have presented mechanically formed long-period fiber gratings using periodically arrayed brass wires with a $250-{\mu}m$ diameter and realized the function of current-controlled wavelength-tuning. With the thermo-optic effect of the surrounding medium around the fiber cladding, the continuous displacement of the resonance wavelengths is achieved through the resistant heat of the wire which changes the refractive index of surrounding material. The tunability for each mode as a function of an applied electrical power is investigated. When the glycerin is used as a thermo-optic material, the measured tuning ranges of $LP_{03}$ and $LP_{04}$ within electrical power of 20 W reach to 14 nm and 48 nm, respectively. The experimental results are in good agreement with the theoretical that which is analyzed by a geometric-optics approximation.
