Subject : The physiological characteristic of Eight Extra Meridians. Objective : This study research physiological characteristic of Eight Extra Meridians that differentiate from the physiological characteristic of Twelve Regular Meridians. Method : First, we researched the meaning of "There are Eight Extra Meridians and they don't be arrested by Twelve Regular Meridians" in Nanjing 27Nan compared with the contents of regular Meridians circulation in Huangdineijing. Second, we studied on the origin of Eight Extra Meridians and researched their route. Third, from these researches we drew some physiological characteristics of Eight Extra Meridians. Conclusion : In Huangdineijing, the regular Meridians circulation include the route of Governor Meridian, Conception Meridian, and Heel Meridian. So the sentence in Nanjing 27Nan is contradictory to the contents of Huangdineijing. The origin of Eight Extra Meridians could be found in Huangdineijing. The collateral Meridians of the Uterus and Epiglottis Meridian are specifically formulated to supplying for the Uterus or Epiglottis. Eight Extra Meridians have third qualities of Meridian, collateral Meridian, and the solid viscera keep the Essence Gi, so named 'Extra'. And they have an intimate association with Extraordinary Organs. They place at the middle axis of human body, thus do higher physiological function that control and regulate the function of Twelve Regular Meridians and Five Viscera & six Bowels for adaptation to the environment.

This paper is to find out the reason why students often make mistakes with 0 during computation and to get some instructional implication. For this, history of 0 is reviewed and mathematics textbook and workbook are analyzed. History of 0 tells us that the ancients had almost the same problem with 0 as we have. So we can guess children's problems with 0 have a kind of epistemological obstacles. And textbook analysis tells us that there are some instructional problems with 0 in textbooks: method and time of introducing 0, method of introducing computational algorithms, implicit teaching of the number facts with 0, ignoring the problems which can give rise to errors with 0. Finally, As a reult of analysis of Japanese and German textbooks, three instructional implications are induced:(i) emphasis of role of 0 as a place holder in decimal numeration system (ii) explicit and systematic teaching of the process and product of calculation with 0 (iii) giving practice of problems which can give rise to errors with 0 for prevention of systematical errors with 0.

The objective of this research is to identify and examine the punk hair styles which, with their various, rather vague names, help to describe the twentieth century subordinate culture or subculture and also their place today as one of the mainstream male hair trends. The scope of this research will stretch to include also: North-east and around that areas native Americans'hair styles which, are thought to have strong links with the Punk hair tend. The focus of this research will remain with the so-called Mohican or Mohawk hair styles(collectively referred to as Punk styles), which have originated mainly from native American warrions residing in North-east and South-east region of the United States. This study clarified a few questions in doubt concerning the origin of cockcomb hairstyle. Firstly, the cockcomb hairstyle known to represent punk hairstyle was influenced the American Indian's Roach style. Secondly, since Roach style is referred as Mohawk tribe's hairstyle in some refernces, the view of seeing cockcomb hairstyle as a Mohawk style is considered more persuasive. Thirdly, although Roach style was a usual hairstyle through North-east and South-east region of the United States, the people in South-east region did Roach hair style because of the North-east's influences. Lastly alike the Punkers had several kinds of cockcomb hairstyle. American Indians'Roach style also differed in shape concerning of their regions and their kindred. In addition, the reason why the most common term to refer punk hairstyle became Mohican is considered as that the film 'Last Mohican' has influenced on it. That film can appeal their history and play a good role of mediator to let the public know better about themselves, 'Mohican' naturally became the name of the specific hair style.

Pagodas in Myanmar can be largely divided into Zedi and Pato. Zedi is a developed form of the early domed pagodas in India and Sri Lanka, which can be found in the introduction of Buddhism in Myanmar and the comparison of early pagodas in India, Sri Lanka and Myanmar. On the other hand, Pato is where statues of Buddha were enshrined, which is why many scholars referred to it as a temple. However, this study proposes that Pato shall be referred to as a temple-style pagoda in a form unique to Myanmar, based on the origin of Pato, definition of pagodas, and Sarira Enrichment Record of Pato. Moreover, it seems more appropriate to name this type of structure Stupa Temple(塔殿) or Stupa Shrine(塔堂) rather than a Buddhist temple(佛殿) or Buddhist shrine(佛堂) for clear distinction. Pato, or temple-style pagodas, has a ${\acute{S}}ikhara-style$ structure at the center like Ananda Pato upon entering the Pagan (Bagan) kingdom period, on which Zedi-style structures are built. As a result of examining the integration of various Buddhist schools and religions focused on Theravada during the period of King Anawrahta and King Kyanzittha, the ${\acute{S}}ikhara-style$ structure is a symbolic representation of the fact that Theravada embraced Hinduism. The common features shared by pagodas in Myanmar are the centrality of place and the verticality of $y{\check{a}}ngti{\bar{a}}n$ (looking up to the sky) in terms of shape. All temples are placed at the most important and central space, and their forms represent strong religious $y{\check{a}}ngti{\bar{a}}n$ and verticality. These are the features that stand out most among various pagodas in Buddhist countries.

The purposes of this study are to understand characteristic water-rock interaction mechanisms of groundwater in the granite area of Geochang and Hapcheon areas, Gyeongnam-do and to clarify the origin of fluoride. The possible water-rock interaction process and the source of fluorine were studied using water chemistry, rock chemistry, mineralogy by XRD, and microtexture analysis by backscattered electron image of the electron microprobe. No clear relationships between F and hardness was found. But the fluorine content increases to some extent with pH and well depth. Preferential alteration due to water-rock interaction took place along edges or cleavage, or margins of biotite. Because biotite is highly subject to alteration in granite aquifer, fluorine in groundwater is originated from the leaching of biotite.

Uraniferous black slates of the Okchon sequence occur in Koesan (northeast) through Miwon-Boun (middle) to the southwest off Taejon (southwest) within the Okchon fold belt. The Uraniferous balck slates in the southwest off Taejon are particularly well developed in Chubu (northeast) and Moksso-ri (middle) areas whereas they are less developed in Jinsan (southwest) area. The uraniferous beds range from less than a meter to 40 meters in thickness and range from less than 0.02% $U_3O_8$ (cut-off-grade) to 0.05% $U_3O_8$ in the southwestern district off Taejon. Electron microprobe analysis of uranium-minerals found in graphitic slate samples enables to estimate their major compositions semi-quantitatively so that uraninite, ferro-uranophane and chlopinite are tentatively identified. Uranium-minerals are closely associated with carbon and metal sulfides. Correlation analysis of trace element concentrations revealed that U and F.C., and U and Mo are lineary correlative respectively and their correlation coefficients are positively high whereas those of U and V, U and Mn, and U and Zr are negatively low, implying that uranium mineralization has been closely related with concentrations of carbon and molybdenum. Stable isotope analyses of pyrite sulfur range widely from +11.5% to -23.3% in ${\delta}^{34}S$ values whereas those of graphite carbon fall within a narrow range between -23.3% and -28.9% in ${\delta}^{13}C$ values. The wide range of ${\delta}^{34}S$ values suggests that the sulfur could be of meteoric origin rather than of igneous source. The narrow range of ${\delta}^{13}C$ values, which are close to those of coal, indicates that the graphite is organic carbon in origin. Therefore, it is concluded that the uranium mineralization in the Okchon sequence took place primarily in sedimentary environment rich in organic matter and sulfide ion, both of which served as the reducing agents to convert soluble uranyl complex to insoluble uranium dioxide.

In that the Buddhism is the religion founded by Buddha, the settlement of Buddha's existence is very important in the temple building arrangement which symbolizes the Buddha's world. What symbolizes the Buddha in the temple are the pagoda and the Buddhist image. Among them, the Buddhist image is directly connected with the Golden Hall. This kind of double structure is settled as a typical pattern for the arrangement of buildings such as halls and pagodas. The earlier one between the pagoda and Buddhist image is the pagoda, of course. It can be inferred that, through the gradual expansion of the Buddhist images, the gravity was transferred from the pagoda to the Golden Hall. But, if the Buddhist image can be connected with the Golden Hall in that it was the product reflecting the requests on the Buddha and his teaching, the internal origin of the Buddhist image should also go back to the early Buddhism. In fact, the gravest building in Venuvana - vihara or Jetavana - anaehapindasyarama was the Golden Hall, the Buddha's residence. And in the summit of Grdhrakuta or Jetavana - anaehapindasyarama where Buddha stayed long, there is the gandha - kuti the Buddha's place till now. It means that the symbolic request on the Buddha and his teaching had existed even before the Buddhist image and that this tendency could be connected with the generation of Buddhist image. This paper is to show that the hall / pagoda structure generalized in the building arrangement of later age was originated not just from the Buddhist image and the sarira pagoda but from the gandha - kuti and the hair pagoda, and therefore the two should coexist inevitably. It is an attempt to develop a little more in the ideological perspective the general theory that the pagoda and the Buddhist image were fused into one precinct of temple later in their respective origins. That is, it tries to recognize the relation of pagoda and hall not as the conflicting one but as the complementary one.

Observational studies of supernova (SN) feedback are limited. In our galaxy, most supernova remnants (SNRs) are located in the Galactic plane, so there is contamination from foreground/background sources. SNRs located in other galaxies are too far, so we cannot study them in detail. The Large Magellanic Cloud (LMC) is a unique place to study the SN feedback due to their proximity, which makes possible to study the structure of individual SNRs in some detail together with their environment. Recently, we carried out a systematic study of 13 LMC SNRs using [P II] (1.189 ㎛) and [Fe II] (1.257 ㎛) narrowband imaging with SIRIUS/IRSF, four SNRs (SN 1987A, N158A, N157B and N206), show [P II]/[Fe II] ratio much higher than the cosmic abundance. While the high ratio of SN 1987A could be due to enhanced abundance in SN ejecta, we do not have a clear explanation for the other cases. We investigate the [P II] knots found in SNRs N206, N157B and N158A, using optical spectra obtained last November with GMOS-S mounted on Gemini-South telescope. We detected several emission lines (e.g., H I, [O I], He I, [O III], [N II] and [S II]) that are present in all three SNRs, among other lines that are only found in some of them (e.g., [Ne III], [Fe III] and [Fe II]). Various line ratios are measured from the three SNRs, which indicate that the ratios of N157B tend to differ from those of other two SNRs. We will use the abundances of He and N (from the detection of [N II] and He I emission lines), together with velocity measurements to tell whether the origin of the [P II] knots are SN ejecta or CSM/ISM. For this purpose we have built a family of radiative shock with self-consistent pre-ionization using MAPPINGS 5.1.18, with shock velocities in the range of 100 to 475 km/s. We will compare the observed and modeled line fluxes for different depletion factors.

This study analyzes the changes in commuter's mode choice between 2002 and 2006 according to the implement of the integrated public transit system in Seoul metropolitan city. Especially this study focuses on differential changes in a transit modal choice among socioeconomic status, trip purpose and spatial characteristics of origin and destination. The probability of public transit use against automobile is modeled as a function of socioeconomic variables, spatial characteristics of origin and destination and the utility of the commuter's mode. The results from conditional logit model analyses suggest that people with lower income show the larger changes in the ratio of public transit choice between 2002-06. Also both higher density, more accessible to public transit and more diverse land uses in residence zone and in work place generally increase the ratio of public transit choice between 2002-06. Car and subway have the most strong alternative relation in commuter's mode choice. The findings give an important implication that the integrated public transit system has differential impacts on commuter's mode choice in Seoul.

The purpose of this study was to survey and analyze the origin story and the legends associated with Yongyudam(龍遊潭, Dragon Creek), its scenic and spatial description in Climbing Writings(遊山記: Yusangi Notes), its geographical and geological features, its surrounding remains and letters chiseled on the rocks through the field study and the study on literatures associated with it so to identify its significance and value and then to ensure justification on preservation of Yongyudam scenic site. Conclusions of this study are as follow. As the traditional scenic place 'Geumdae-Jiri(金臺智異)' representing Hamyang-gun(咸陽郡) depicts Mount Cheonwangbong and 'Yongyudong Village(龍遊洞)', ancient maps and literatures have positioned Yongyudam as the center of Eomcheon-river Creek as well as the representing scenic site of Yongyudong Village. Core images in the spatial awareness of Yongyudam described in our ancestors' Climbing Writings Notes on Jirisan Mount are 'geographical and scenic peculiarity associated with swimming dragons', 'potholes in various shapes and sizes scattered on rocks', 'loud sound generated by swirling from shoals' and 'the scenic metaphor from the dragon legend', which have led scenic features of Yongyudam scenic site. In addition, significant scenic metaphors from legends such as 'Nine Dragons and Ascetic Majeog' and 'Kasaya Fish' as well as 'the Holy Place of Dragon God', the rain calling magic god have descended not only as the very nature of Yongyudam scenic site but also the catalyst deepening its mystic and place nature. On the other hand, Jangguso Place(杖?所, Place of Scholars) in the vicinity of Yongyudam was the place of resting and amusement for scholars from Yeongnam Province, to name a few, Kim Il-son, Cho Sik, Jung Yeo-chang and Kang Dae-su, where they experienced and recognized Jirisan Mount as the scenic living place. Letters Carved on the rocks at Jangguso Place are memorial tributes and monumental signs. Around Yongyudam, there are 3 stairs, letters chiseled on the rocks and the water rock artificially built to collect clean water, which are traditional scenic remains detectable of territoriality as the ritual place. In addition, The letters on the rock at Yongyudong-mun(龍遊洞門) discovered for the first time by this study are the sign promoting Yongyudam as the place of splendid landscape. The laconism, 'It is the Greatest Water in Jirisan Mount(方丈第一山水)' on a rock expresses the pride of Yongyudam as the representing scenic place of Mount Jirisan. Other than those, standing rocks such as Simjindae Rock, Yeong-gwidae Rock and Ganghwadae Rock show the sign that they are used as amusement and gathering places for ancestor scholars, which add significance to Yongyudam. By this study, it was possible to verify that Yongyudam in Mount Jirisan is not simply 'the scenic place in the tangible reality' but also has seamlessly inherited as the traditional scenic attraction spiritualized by overlapped historical and cultural values. Yongyudam, as the combined heritage by itself, shows that it is the product of the place nature as well as unique ensemble of cultural scenic attraction inherited through long history based on natural scenery. It is certain that not only the place value but also geographical, geological, historical and cultural values of Yongyudam are the essence of traditional scenic attraction, which should not be disparaged or damaged by whatever political or economic interests and logics.
