The purpose of this study is the approach to I.I.C.P. centered on the meaning of consciousness disorder and the pathological aspect of Kwul (Jose consciousness ; faint, fall into a coma). The meaning of consciousness disorder and apoplexy is evidently involved the definition of Kwul. 1. It is found that the etymological interpretation on Kwul which the energy rises back to go through blocked space and the meaning interpretation of regarding Kwul as apoplexy with medical viewpoint, are related with consciousness disorder and motor disturbance in IICP in the aspect of the rise of Kwul and the abnormal rising of vital energy and blood, In addtion, the overall of meaning of Kwul is showed in table <1-1> by reference to doctors of many generations, 2. The pathology of Kwul includes abnormal rising, sthenia-syndrome in the upper part and asthenia in the lower, the origin of Kwul, the lower, looking like Yin by too sthenic Yang and looking like Yang by too sthenic Yin. The headache, vomiting, papilledema, paralysis of nervi craniales, coma, blood pressure rising, tachycardia by I.I.C.P can be regarded as a conception of trouble of vital energy, sthenia-syndrome of Kwul. The pulse pressure, brachycardia, bradypnea can be regarded as the conception of looking like Yin by too sthenic Yang. 3. In the emergency of Kwul, the abnormal ternimal reversion of the Kwulyin channel, Kuyang channel, and three Yins are related with the phenomenon in I.I.C.P. It is considered that the reverse movement of materials, I.I.C.P. can be closely observed by giving meaning on the meridian of Kwul in Somunkwulron. And the content of phrases of Naelyung which includes consciousness disorder refered in the chapter of Kwul, is compared with I.I.C.P. 4. The followings should be considered; examination of optic symptom and abnormal posture in cerebral herniation ; understanding and working out counterplans of factors and symptoms of consciousness disorder by the observation of vital sign, check of general stages, neurologic inverstigation, clinical diagnosis, and subsidiary diagnosis; application of morphological change of opinion; addtion of the conception of demonstration centered on Yunkyung, Samyinkwulruk, asthenia and thenia of healthy energy in oriental medicine. 5. The similarity of Kwul and I.I.C.P. can be found from etiology and pathotenic factor. The similarity is clearly found by investigation of etiology, pathotenic factor, symptoms and thrapy of Kwul, disease symptom ar.d other symptoms.

This study was conducted to examine the genetic variations and intraspecific relationships between 9 individuals of Panax ginseng C.A Meyer by using RAPD (Randomly Amplified Polymorphic DNA) analysis. The 34 primers out of 40 random primers were amplified for all tested plants. The 48 (40%) among 244 bands derived from 34 primers shown polymorphism, and the 72 (64%) rest of bands showed similar forms. By regional groups Sangju and Andong samples located in Kyungsang buk-do showed a high similarity. However, Punggi located in Kyungsang buk-do showed higher similarity with Jinan's of Junla buk-do. In this way, it did not show that Panax ginseng from the same area has similarities. In future study we need to more specific molecular phylogenetic analysis such as AFLP technology and gene sequencing with nuclear chloroplast DNA in all samples.

In the case of military supplies, any potential failure and causes of failures must be considered. This study is aimed at examining the failure modes of a rotorcraft landing system to identify the priority items. Failure mode and effects analysis (FMEA) is applied to the rotorcraft landing system. In general, the FMEA is used to evaluate the reliability in engineering fields. Three elements, specifically, the severity, occurrence, and detectability are used to evaluate the failure modes. The risk priority number (RPN) can be obtained by multiplying the scores or the risk levels pertaining to severity, occurrence, and detectability. In this study, different weights of the three elements are considered for the RPN assessment to implement the FMEA. Furthermore, the FMEA is implemented using a fuzzy rule base, similarity aggregation model (SAM), and grey theory model (GTM) to perform a comparative analysis. The same input data are used for all models to enable a fair comparison. The FMEA is applied to military supplies by considering methodological issues. In general, the fuzzy theory is based on a hypothesis regarding the likelihood of the conversion of the crisp value to the fuzzy input. Fuzzy FMEA is the basic method to obtain the fuzzy RPN. The three elements of the FMEA are used as five linguistic terms. The membership functions as triangular fuzzy sets are the simplest models defined by the three elements. In addition, a fuzzy set is described using a membership function mapping the elements to the intervals 0 and 1. The fuzzy rule base is designed to identify the failure modes according to the expert knowledge. The IF-THEN criterion of the fuzzy rule base is formulated to convert a fuzzy input into a fuzzy output. The total number of rules is 125 in the fuzzy rule base. The SAM expresses the judgment corresponding to the individual experiences of the experts performing FMEA as weights. Implementing the SAM is of significance when operating fuzzy sets regarding the expert opinion and can confirm the concurrence of expert opinion. The GTM can perform defuzzification to obtain a crisp value from a fuzzy membership function and determine the priorities by considering the degree of relation and the form of a matrix and weights for the severity, occurrence, and detectability. The proposed models prioritize the failure modes of the rotorcraft landing system. The conventional FMEA and fuzzy rule base can set the same priorities. SAM and GTM can set different priorities with objectivity through weight setting.

Oral literature can largely be categorized into myth, legend, and folktales, which are stories orally transmitted from the prehistoric times. The purpose of this study is to compare the discourse on the oral literature of the East and the West from a cultural studies viewpoint by focusing on its "symbolic systems," particularly "figures of speech," or "tropic traits", in order to utilize this oral literature as a resource in the study of Northeast Asian culture. Undergoing modernization, the symbolic meaning of oral literature has been demythologized both in the West and in Northeast Asia. Of course, oral literature, verbally transmitted over a long period of time, has naturally been changed over time and even "contaminated" in a sense by losing its original archaic archetype while it was textualized with letters during the early period of the modernization process. Nevertheless, the principle of "resemblance" and "similarity" between nature/universe and human/humanity, which has been stripped away in modernity, can still be found in oral literature with its mythic power. For this reason, the study of oral literature in the West has attempted to restore the lost magical power within it, particularly in myth. As such, this study delves into the symbolism of the mythic thought of Northeast Asian countries, namely Korea, China, and Japan, which has been lost in the course of their compressed modernization, in relation to the tropic figures of their oral literatures.

The Gugogdong-Horyongbong valley forest in Odaesan National Park area was studied to investigate forest structure in relation to altitude and part of slope. Forty-eight quadrats were set up in the valley forest along altitude of 800m to 1,500m and part of the slote. With increasing elevation the important values of Quercus mongolica and Rhododendron schlippenvachii increased, while those of Abies holophulla, Ulmus davidiana var. japonica and Lindera obtusiloba decreased. As going from lower part to upper part of the slope, the importance values of Quercus mongolica and Rhododendron schlippenbachii increased while those of Acer mono and Ulmus laciniata decreased. Species diversity tended to decreased as increasing elevation. The range of similarity indices between elevation belts, and parts of the slope were 56.3~73.4% and 61.9~71.8%, respectively. According to importance value and cluster analysis, the studied valley forest was classified into tree forest communities of Abies holophulla-deciduous tree species community in lower and middle parts of slope at low and middle elevation belts, Quercus mongolica- coniferous tree species community in upper part of slope at low and middle elevation belts and lower and middle parts of slope at high elevation belt and Quercus mongolica community in upper part of slope at high elevation belt and top area.

The data model that can be said as skeleton of the information system constitutes important 2 axles in the information system together with the process model. There is entity, properties, relation as key factors of the data model, and entity is the most fundamental factor in the data model, and thus total data model becomes vague if not deriving entity definitely. This study dealt with entity deduction only. Deducing methods of existing entity depended on experiences, task knowledge of designers and clear procedures were not suggested, so there were many difficulties in approaching them from beginners or unskilled persons. For giving helps in solving the problem, this study proposes entity- deducing procedures based on tasks that can derive entity with a systematic process at previously derived target businesses through suggested methods from advancing researches. And the study enabled proposing procedures on imaginary tasks to be applied, objecting to undergraduates who had not experiences on the data modeling, and then verified suggesting process through a similarity checking between best answers with deduced entity by students after taking impossible points of comparing existing methods with suggesting process into consideration. By doing so, deducing entity closely to the best answer was confirmed accordingly. Therefore, a fact could be confirmed that beginners were able to deduce entity closely to the best answer even if letting beginners who had not experiences on the data modeling be applied to unfamiliar tasks. Regarding researches on properties and relation deduction besides entity, this study leaves them to next time.

The Yangsan fault system of Kyungsang Basin in the southeastern part of Korean peninsula is one of the most important structures in the peninsula. A number of strong earthquakes occurred in the vicinity of the fault. It was suggested that this fault can be divided into three segments: northern, central and southern ones. Earthquake data around the Yangsan fault were classified into two groups as incomplete and complete ones; the former is the data before the Choseon Dynasty and the latter is those since the dynasty. The maximum likelihood method was applied to compute seismicity parameters such as earthquake occurrence rates, b-values of frequency-magnitude relation and maximum possible magnitudes for each segment and the entire fault. These parameters show considerably different values from segment to segment. The b-value for the entire fault turned out to be 0.85 and maximum possible magnitudes for the northern, central and southern segments are 5.2, 6.8 and 6.0, respectively. The mean return periods for the maximum possible magnitudes for each segments are greater than 1000 years. In addition, according to the analysis of the frequency-magnitude relation, the occurrence pattern of earthquakes around the Yangsan fault show more similarity to the characteristic earthquake model than the Gutenberg-Richter model. The data for each segments are, however, too scarce to obtain any physically meaningful results.

The Chungju and Seosan Groups have been known usually as Precambrian formations in Korea. But their relative and absolute ages have been controvericial problem in relation with other geologic system such as so-called Ogcheon and Yeoncheon Systems in Korea. This study has mainly focused on the corelation of the Chungju Group with the Seosan Group in their stratigraphy, structure, metamorphism, and iron ore deposits. In the process of study, the auther surveyed and reclassified the Chungju and Seosan Groups and corelated with Gyeonggi and Ogch cheon metamorphic belts and got some new data. The Chungju iron-bearing formations showing transtitional relation with the Gyeonggi Gneiss Complex and the Jangamri Formation consisting mainly of pebble bearing calcarious phyllite, should be seperated from the Gyemyeongsan formation which is mainly composed of metavolcanic rocks. The Jangamri Formation and the coaly phyllite, which can be corelated respectively with the Hwaggangri Formation and Changri Formation in Ogcheon Group, are repeated in the Gyemyeonsan and Munjuri Formations with the overturned anticlinal folding(F1). So the Chungju Group which was defined as an indipendant geologic unit from the Ogcheon Group should be limited only on the Chungju iron Formation. The Seosan Group can be classified stratigraphically such as Seosan Formation consisting of iron-bearing quartzite and mica schist, Daesan Formation overlying unconformably on the Seosan Formation and Gyeonggi Gneiss Complex. Taean Formation overlying unconformably on the Daesan Formation should be seperated from Seosan Group. There are many similarity in the stratigrphy, structure, and metamorphic facies between Chungju and Seosan Groups exept the metavolcanic rocks in the Gyemyeongsan and Munjuri Formations and the pebble bearing calcareous phyllite in the Jangamri Formation. The two Groups were deformed with two kinds of differant stages, the first shows $N30^{\circ}-40^{\circ}E$ trend of fold axis, the second $N70^{\circ}-80^{\circ}W$ respectively. The Seosan Formation, which is the lowest formation in Seosan Group and bearing the iron formation, was metamorphosed at 2500 m. y. before. These age is similar with the metamorphic age of Gyeonggi metamorphic belt and with the age of Algoman and Kenoran Orogenies which devide the Precambrian into Archean and Proterozoic Era. So the Seosan Formation, which is included in some migmatitic rocks of Gyeonggi Gneiss Complex, is the oldest formation in Korea and can be corelated with the Anshan Group which bears the oldest iron formation in China. The metamorphic facies of the Precambrian metamorphism in Seosan area is simillar with that of Chungju area, showing high temperature-low pressure amphibolite facies which is corelated with the Gyeonggi metamorphic belt, the oldest metamorphic belt in Korea ($650^{\circ}-680^{\circ}C$, 3.2-4.4 Kb). The high temperature intermediate pressure amphibolite facies in Seosan area with the low temperature-intermediate presure greenschist facies of Taean formation is corelated with that of Ogcheon Group ($590^{\circ}-640^{\circ}$ C, 5.2-6.3 Kb). The Chungju and Seosan iron formations were deposited in Archean, showing geochemical composition of Precambrian iron formations. The Chungju iron formation was mainly formed by the chemical precipitation, on the other hand, the Seosan iron formation was formed by alternated action of chemical and detrital depositions.

The Shindae resting place-Jibong valley forest in Tokyusan area was studied to investigate forest structure in relation to altitude and part of slope. Forty eight quadrats were set up in the valley forest along altitude of 750m to 1,247m and part of the slope. Density of trees in tree strata decreased as increasing elevation, and mean DBH of trees in tree strata increased as increasing elevation. With increasing elevation the importance values of Quercus mongolica, Acer mono, Fraxinus mandshurica increased, while those of Quercus serrate, Betula schmidtii decreased. As going from lower part to upper part of the slope, the importance values of Quercus mongolica and Symplocos chinensis for. pilosa increased while those of Cornus controversa and Fruxinus mandshurica decreased. The number of species, species diversity and evenness tended to decreased as increasing elevation. The range of similarity indices between elevation belts, and parts of the slope were 55.3~67.1％ and 36.8~71.7%, respectively. According to importance value and cluster analysis, the studied valley forest was classified into four forest communities of Quercu serrata community of lower part of slope of low elevation belt, Quercus mongolica-Quercus serrata community of middle and upper part of slope of low elevation belt, Quercus mongolica-deciduous tree species community of middle and high elevation belt and Quercus mongolica-Rhododendron schzippinbachii community of the top area.
