Acupuncture and moxibustion play an important role not only in the medical service and health care of Korea, China and japan but also in those of many western countries such as Germany, France, United States of America. An unexpected results induced by careless acupuncture and moxibustion treatments may be mild or severe, and are due to practitioner's mistake and particular body condition of a patient. This study was performed to establish a preventive measures against medical accident induced by acupuncture therapy. Total 23 acupuncture points which are included in a J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ were selected as prohibited acupuncture points. Although the records in J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ are an important data historically which show dangerous acupuncture points, there are few a full investigation on J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ up to the present. So present study was done for literature review to understand a feasibility of the records in J${\bar{l}}$n-Zh${\dot{e}}$n-Xu${\acute{e}}$-G${\dot{e}}$ in association with dangerous acupuncture points. Based upon the locations of these acupuncture points, the dangerous region were classified three categories, head, soma and limb. And abnormal signs related to the improperly performed acupuncture treatment on each point were investigated by using historical reference books on acupuncture and moxibustion. And then names, locations, depth of insertion, operation methods and side effects of each point were investigated.

Generation of abnormally large grains in the microstructure of small grains has been investigated on some ferrites. Some fractions of large grains were observed in the microstructue of sintered ZnFe$_2$O$_4$, Mn-ZnFe$_2$O$_4$, Fe$_3$O$_4$(in $N_2$) and MnFe$_2$O$_4$(in air). On the other hand, the large grains were not observed in $NiFe_2$$O_4$ and $CoFe_2$$O_4$, independent of calcining and sintering conditions. The large grains seem to be generated in such ferrites that are easy to very their compositions or valencies at high temperatures. as the sintering proceeded, the number of large grains was increasing to from a continuous structure consisting of large grains, while the size of large grains did not increase remarkably. In addition, the growth of small grains was also very slow during the generation of the large grains. The large grains appeared be suddenly generated after some induction periods. Avrami equation could be applied to the relation between net volume of large grains and sintering time. Thus, the grain boundaries may be strongly stabilized when the large grains are generated. The large grain is generated y the local activation of the stabilized rain boundaries, which is caused by the variation of composition or valencies during sintering. It is concluded that the essence of the abnormal gain growth is not the generation of abnormally large grains, but the abnormal stabilization and the local activation of he grain boundaries.

'Movement System' is made of the interaction of user and architectural spaces related to each other in order. 'Movement' meant in movement system is possible only in the status of user and architectural space together. Movement created and disappeared by the user is not subordinated to the existing architectural space but becomes the main element of formating movement system. It is required that movement conception applied to architecture should be derived from the essence of movement and this study presents the movement system. To explain the formating process of movement system, A. N. Whitehead's process philosophy theory is at the basis and transformed in architectural aspects. On basis of these theoretical backgrounds, the process of making movement system can be explained. There are unit movement, unit object, and elements for movement process as the basic requirements for movement system, each unit is apprehended by individual operation and the nexus is composed by associative operation of apprehended units. This nexus becomes the object of a new subject and forms multiple nexus. Relation of unit movement and unit object and nexus are apprehended as the continuation and extensive continuum is made. At that time, movement with multiple phases set inbetween systems and extended multiplied. Through above study, movement system is applied to Korean traditional houses.

A series of carbon nanotube, $C_{60}$, and graphene modified $TiO_2$ nanocomposites were prepared by hydrothermal method. X-ray diffraction, $N_2$ adsorption, UV-Vis spectroscopy, photoluminescence, and Electrochemical impedance spectra were used to characterize the prepared composite materials The results reveal that incorporating $TiO_2$ with carbon materials can extend the adsorption edge of all the $TiO_2$-carbon nanocomposites to the visible light region. The photocatalytic activities were tested in the degradation of 2,4,6-trichlorophenol (TCP) under visible light. No obvious difference in essence was observed in structural and optical properties among three series of carbon modified $TiO_2$ nanocomposites. Three series of carbon materials modified $TiO_2$ composites follow the analogous tentative reaction mechanism for TCP degradation. GR modified $TiO_2$ nanocomposite exhibits the strongest interaction and the most effective interfacial charge transfer among three carbon materials, thus shows the highest electron-hole separation rate, leading to the highest photocatalytic activity and stability.

This research aims to make the general plan for the preservation and practical use about Junkyung and Youngkyung tombs at Samcheok. The general plan is classified according to three large territories. First, it is necessary for these two tombs to preserve territories and strengthen the historical identity in order to restore the spoiled building such as Subokbang and Surabang by verification and excavation. Second, to preserve the nature and environment of territories surrounding the two tombs is essential for the extension of the essence about these cultural heritage to improve the familiarity and effective utilization by trial programs, which are related to the historical background of the tombs and so forth. Third, supporting and making convenient facilities in the neighborhood near cultural assets is required to install public parks and parking lots for visitors. Additionally, it is needed to advertise successively about these two tombs as the beginning of Chosun Dynasty tombs Also, it is necessary to consider implementing programs because Junkyung and Youngkyung tombs along with Chosun royal tombs in the north of Korea might be designated as World Culture Heritage if Korea should be a unified nation.

We report a newassay method on the measurement of the catalase activity, whose utilzation value is considered to be remarkable in the field of plant biochemistry. We named this method as a De-Coupling method. The essence of de-coupling method is the separation between the enzyme reaction and the indicator reaction. The optimum condition of the enzyme reaction was found to be following: on addition of 1 ml of substrate (H2O2: 20mM) to the fixture of the crude extract of enzyme (volume: 0.2 ml) and the ammonium phosphate buffer (volume: 1.8 ml; 0.93 M phosphate, 1.6M NHB, 2.5 M methanol, pH 7.0). After 30, 60 and 90 seconds of the enzyme reactions are proceeded, the reactions are terminated by 25% of tai-chloro-acetate (final concentration of 5%), respectively. The precipitated materials by tai-chloro-acetate was removed by the centrifugation (2000g, 10minutes). Formaldehyde produced in the enzymatic reaction was reacted with 2ml of acetylacetone (60mM). The indicator reaction -(HANTSCH REAKT10N)- in which lutidine is formed, was proceeded for 60 minutes at $25^{\circ}C$.

This study was aimed to explain the essence of Hydroxylammonium hydrochloride(H.A.) effect on degummed silk fiber increasing the colour sites due to oxime generating reaction. H.A. in aqueous solution caues to increase the amount of [H+] and reduce pH values as the concentration of H.A. increases. The rate of [H+] absorption of silk fiker in acidic solution differs on the basic of solution pH and shows a specific uptake in each pH, the lower the pH of solution, the higher the amount [H+] absorption. The pH of solution after treating of silk fiber in H.A. and HCl, showed more remaining [H+] in H.A. solution due to [H+] releasing under the procedure of oxime production. Also it was revealed that in higher concentration of H.A. the reaction for oxime fixation in silk fiber carried out stonger and as a result the bigger gap with acid uptake curve appeared. FT-IR analysis of silk fiber treated with H.A. revealed the creating of intermolecular H-bond at the 2,981-2.930 cm-1, which was not appeared for nontraeted silk fibers and shows H-bond between N-OH group in oue chain and C=) group in another chain of silk protein. Colourimetry of dyed silk fiber after H.A. tratment showed that the silk fiber treated with the high concentration of H.A. compare to low concentration, absorbed more dyeing molecules and so Showed less percontage of Whiteness.

Within the context of Structural Health Monitoring (SHM), it is often the case that structural systems are described by uncertainty, both with respect to their parameters and the characteristics of the input loads. For the purposes of system identification, efficient modeling procedures are of the essence for a fast and reliable computation of structural response while taking these uncertainties into account. In this work, a reduced order metamodeling framework is introduced for the challenging case of nonlinear structural systems subjected to earthquake excitation. The introduced metamodeling method is based on Nonlinear AutoRegressive models with eXogenous input (NARX), able to describe nonlinear dynamics, which are moreover characterized by random parameters utilized for the description of the uncertainty propagation. These random parameters, which include characteristics of the input excitation, are expanded onto a suitably defined finite-dimensional Polynomial Chaos (PC) basis and thus the resulting representation is fully described through a small number of deterministic coefficients of projection. The effectiveness of the proposed PC-NARX method is illustrated through its implementation on the metamodeling of a five-storey shear frame model paradigm for response in the region of plasticity, i.e., outside the commonly addressed linear elastic region. The added contribution of the introduced scheme is the ability of the proposed methodology to incorporate uncertainty into the simulation. The results demonstrate the efficiency of the proposed methodology for accurate prediction and simulation of the numerical model dynamics with a vast reduction of the required computational toll.

Ji Cheng''''s great work on garden design theory, the ''''Yuanye'''', written in 1631 and originally published in 1634 is the first surviving treatise and most famous and comprehensive work on the suvject in the Chinese tradition. He constructed Dongdiyuan in Changzhou about 1623, Wuyuan in Yizheng in 1631, and Yingyuan in Yangzhou about 1634. But no poems and paintings written by him still exist, and none of his known gardens has survived. Therefore his design philosophy is able to be interpreted only by his work, Yuanye. This study aims at investigating the garden design theory in Yuanye. The results were summarized as follows. 1) Yuanye reflected the garden tastes of literati, and Ji Cheng endeavored to express the deas of literati painting into gardens. 2) The essence of the garden design theory is Xingzao, and Yindi, following the existing lie of the land, and Jiejing, to borrow from the scenery, are two major activities of Xingzao. 3) Ji Cheng''''s design theory build up on the basis of recognizing the existence of masters. 4) Yindi is the environmental and ecological planning and design method. This is the activity to reach the state of artistry through suitability. 5) Jiejing is not merely borrowing the landscape but the making use of scenery around the garden. And only the master has the skill in fitting in with the form of the land. 6) Ji Cheng pursuits the garden which will look like something naturally created though manmade. It is the goal of the Chinese traditional gardens and ideal situation. 7) Ji Cheng aims to unify the environment and landscape design dialectically into Xingzao.
