The AIN/AI thin films were prepared at various conditions, such as $N_2$ gas flow rate [$N_2(N_2+Ar)$] from 0.6 to 0.9, a substrate temperature ranging from room temperature to $300^{\circ}C$ and working pressure 1mTorr. We estimated crystallographic characteristics and c-axis preferred orientations of AIN/AI thin films as function of AI electrode surface roughness. The optimal processing conditions for AI electrode were found at substrate temperature of $300^{\circ}C$ sputtering power of 100W and a working pressure of 2mTorr. In these conditions, we obtained the c-axis preferred orientation of $AIN/AI/SiO_2/Si$ thin film about 4 degree.

In this study, we investigated whether Hibiscus manihot flowers (HMF) exhibits immunostimulatory activity in RAW264.7 cells. HMF increased the production of immunostimulatory factors such as NO, iNOS, IL-1β and TNF-α in RAW264.7 cells. TLR2 and TLR4 blocked HMF-mediated production of immunostimulatory factors in RAW264.7 cells. In addition, the inhibition of MAPK signaling pathway reduced HMF-mediated production of immunostimulatory factors. From these results, HMF is thought to promote the production of immunostimulatory factors through activating TLR2/4/MAPK signaling in macrophages. It is believed that HMF can be developed as an agent related to immune enhancement in the future.

This book was completed in the 33rd year of Gang-hui-gapsul(康熙 甲戌) in the Cheong(淸) dynasty(1694), and was first inscribed in the 55th year of Geonryung(乾隆). In this first edition named 'Daechudangbon(大雅堂本)', his descendant Jinbonghui(陳鳳輝) wrote the postscript. There are also other editions such as 'Ga-gyeong-ganchwihyeondangbon(嘉慶間聚賢堂本)', 'Wimundanggeonsangbon(緯文堂巾箱本)' and 'Guangseo-ganseonseongdangbon(光緒間善成堂本)' Second, this book was called "Oe-gwabirok(外科秘錄)" and used the pen name 'Gibaekchunsasojeon(岐伯天師所傳)'. There are 16 volumes in total. The beginning of volume one, is a drawing of the 14 meridians. Volumes 1$\sim$4 are on the symptoms and treatment of abscesses and sores and ulcers[癰疽瘡瘍]. Volumes 5$\sim$13 are on surgery, dermatology and 156 diseases such as wounds by contusion, sharp objects and insects and beasts[跌撲, 金刃, 蟲獸傷]. Volumes 14$\sim$16 list the internal treatments, external medicine, acupuncture and moxibustion and surgery of sores and ulcers. Third, the book stressed early detection and treatment of diseases, emphasized inner resolving[內消] being cautious about using medicine, and further deepened the syndrome differentiation and treatment[辨證施治] of sores and ulcers[瘡瘍] by dividing fire toxin(火毒) into Eumhwa and Yanghwa(陰火/陽火). Also, it established the cause of sores and ulcers development as the deficiency of Gi(氣) and blood[血] and focused especially on the liver and kidney's involvement in the process. It also asserted that the pathogen[邪] is the tip[標], so one should eliminate and reinforce[攻補] to balance it out. The sore and ulcer surgery[瘡瘍外科] part is mostly based on detoxifying[解毒] and resolving[消散]. Although the meridians were mentioned, they were not emphasized, while moxibustion treatment of sores and ulcers[瘡瘍] were thoroughly analyzed. Also, of all 550 formulas in this book, 90% are experience-based which frequently use Geum-eunhwa(金銀花), Pogong-yeong(蒲公英) and Jahwajijeong(紫花地丁). The usages are unique, and the formulas have good adaptability. The symptoms of the diseases are explained first, followed by according main and sub treatments.

The purpose of this paper is to improve the service tree analysis introduced recently by Geum et al. [15]. Service tree analysis structures the service based on the customer participation perspective and provides a qualitative analysis method categorizing the service elements on the basis of its impact to top service. This paper attempts to apply the concept of reliability importance to the service tree analysis as a perspective of quantitative analysis, which is considered little in Geum et al. [15]. Reliability importance is a measure of the structural impact of the components that make up the system on the system lifetime in reliability engineering field and often used in fault tree analysis. We transform the reliability importance into service importance in accordance with service tree analysis, so that the influence of service elements on the service can be judged and compared. The service importance is defined as the amount of change of the service according to the change of the service element, therefore, it can be utilized as an index for determining a service element for service improvement. In addition, as an index for paired service elements, the relationship between the two service components can be measured by joint service importance. This paper introduces conceptual changes in the process of applying reliability importance to service analysis, and shows how to use the service importance for identifying the priority of service element for the final service and improving customer satisfaction through an example. By using the service importance and joint service importance in service tree analysis, it is possible to make efficient decision making in the process of determining the service elements for analyzing and improving the service.

In Cheon Won Gi Dae Ron(天元紀大論), Cheon(大) means Nature, Won(元) means sources, Gi(紀) is Gang Gi(綱紀) that means rules or regulations, so Cheon Won Gi(天元紀) means sources and rules of change that make Nature phenomenons. This volume treats of cause that weather change of Nature caused by, and its general rules, and presents fundamental notions and systems of measuring of 'Five elements' evolutions and Six kinds of natural factors(五運六氣)'. So named Cheon Won Gi Dae Ron(天元紀大論). This article of the research on the Cheon Won Gi Dae Ron(天元紀大論) can be divided into 3 chapters. Chapter 1 presents a theory that the principle of changes of creations' birth, groth and extinction is complished by sympathizing with Hyeong(形) of Ji(地) and Gi(氣) of Cheon(大) by rules of movement of O Un Yum Yang(五運陰陽). Chapter 2 presents theories that Tae Heo(太虛) makes Won Gi(元氣), and this Won Gi(元氣) makes the change of creations' birth, groth and extinction, and movement of O Un(五運) controls creation of nature. And treats of that 'excessive and short(太過不及)' that is made by a quality of Gi(氣) and ups and dons of Hyeong(形) controls weather of year. In Chapter 3, Cheon O Ji Yuk(天五地六) regard six and five as Yong(用). And A Cycle that movment that sympathizing with O Un(五運) and Yuk Gi(六氣) is Il Gi(一氣) as 30 years, and Il Ju(一周) as 60 years. And presents that O Un(五運) and Yuk Gi(六氣) that Gan Ji(干支) control.
