In building geographic information for North Korea, we proposed the method of using SPOT-5 image, designed geographic information layers, and inspected the location accuracy. Basically this study is similar to existing method in which uses GCPs to build geographic information from SPOT-5 satellite imagery. However, this study adopted a different method of GCP acquisition. The GCP used in this study is a triangulation point which was made at Japanese imperialism eras. The location accuracy error was 8.755 meters horizontally, which satisfied the tolerance of 17.5 meters in the 1:25,000 scale public survey guidance. In conclusion, we suggest that geographic information for North Korea can be built from SPOT-5 images with the triangulation point made in Japanese imperialism times.

This study aimed to analyze the historical evolution of general ideas concerning the particles that represent matter properties and matter changes divided into physical change and chemical change. In the science historical viewpoint, the general ideas of the base that represent matter properties has been variously revised the 5types. The definition of the matter change have also changed the 3 types. From the analysis of the definitions in secondary school science textbooks and general chemistry textbooks, we found that a lot of confusion of eras in the contents that define the concepts. Sometimes, the definition presented in one textbook was contradictory to the definitions in other textbooks. This tendency has been sustained in the textbooks from the 4th to 7th science curriculum.

The two Korean words, Solon-Tang and Su-Ra-Sang, are generally assumed as the names of Mongolian foods which seem to have been used in Korea due to the influence from the enhanced close relationships between Mongolia and Koryo. This indicates that the two words have very important meaning in stdying the relationship between the food culture in the central asia in those days and the terminologies used in the palaces in the eras of Koryo and chosun and so have attracted continuously the related scholars‘ attention. 1. The theory of folk etymology; it is originated from its cooking that first they cut meat into small pieces and put them into a cauldron and boil sulrong sulrong (which means such boiling state in that its water bubbles up) for a along time. 2. Early of the chosun time, the king himself comes to 'Sun-Nong-Dan' where he teaches the people how to farm and hold a large festival and after that they boil the cow meat soup and feed the people around there. At that time, they name and call the kuk-bub (soup with rice) which they eat at the 'Sun-Nong-Dan' 'Sun-Nong-Tang'. 3. The India Sanskrit Sura, a kind of liquid (in which component that have someone who takes it drunken) which gods enjoy themselves over, comes into the palace on the latter half of Koryo time via Mongolia and affects and becomes the Korean words. 4. The Mongol Suru or Sulru which is a cooking in that they boil meat putted in plain water comes into Korea under the special historic relation between Mongolia and becomes Solon-Tang. For the details of the above mentioned theories, we will fully discuss the origin through studying concretely the related books and mutual comparing history, linguistic periods and phonetic changes accordingly and the changes in meaning and vocabulary forms here.

In the new media age, the importance of personal style is highlighted, as the fashion recipients independently create their own images by transforming and recombining the fashion information gathered from the fashion blogs - the most representative form of social networks. The study aims to identify the types and styles of imaginary ego-images represented on the personal fashion blogs as a new space of self-expression, based on Lacan's gaze; the imaginary of the unconscious world and the ego-concept. According to literature search, the imaginary ego-image is classified as narcissism, regression, identification, and virtuality. In the case study, Narcissism is represented mostly as bloggers' satisfaction and beliefs about their fashion styles. The degeneration represents childhood images including a mother, as well as retro and vintage images that recreate the fashions of bygone eras - such as medieval, $19^{th}$ or 20th century fashion. Identification is the connection with the various areas of culture and art, especially movies and music. Virtuality represents hypothetical situations of mythical, fairy tale-like, surreal, or dreamlike atmospheres and hypothetical bodies that appear removed, disassembled, or crooked. The imaginary ego-images emerged on the personal fashion blogs are also classified into specific style depending on the attributes of the ego images-such as kidult style, retro style, ethnic style, and surreal style.

1. Purification of amylase system produced from Humicola sp. by a submerged culture eras carried out. 2. By DEAE-Cellulose column chromatography amylase system was separated into two fractions eluted at 0.05M and 0.5M phosphate buffer solution of pH 6.0. 3. The saccharogenic amylase was mostly composed of. the fraction of 0.05M phosphate buffer solution of pH 6.0 while the dextrinogenic amylase was perseted in fraction of 0.5M phosphate buffer solution of pH 6.0 4. It was found that the optimum pH of this saccharogenic amylase was within the range of from 4.5 to 5.5, stable pH was within the range of from 4.0 to 9.0 and optimum temperature was $60-65^{\circ}C$. This amylase was stable at $70^{\circ}C$ for ten minutes but completely inactivated $80^{\circ}C$ above.

Modified radish Kimchi and radish-root juice were fermented under $N_2$ atmosphere at $22{\sim}23^{\circ}C$ and $37^{\circ}C$, respectively and their changes of vitamin C content. were determined by dinitrophenylhydrazine and indophenol methods. In the earlier period of the fermentation, vitamin C content decreased temperarily and then began to increase. When the flavor of Kimchi was most acceptable, vitamin C showed the maximum value which eras equivalent to or more than the initial, after which vitamin C content decreased gradually. The increase of vitamin C content seemed to come from the biosynthesis of the vitamin owing to the enzymatic action occurred in radish-root. The addition of galacturonic acid to Kimchi and to radish-root juice elevated the vitamin C content, which suggested galacturonic acid was a good substrate for the synthesis of vitamin C. The optimum pH of the Kimchi fermentation for the better vitamin C content ranged 4.0 to 4.5.

The Korean have admired and lived with decorums through Jeol, a representative practical formality which expresses the decorums intensively. Jeol is the way of greeting native to Korea and an intangible culture close to Korean life style. To be remained as a culture, the traditional propriety Jeol should reconcile to the present life feflecting our history. On this viewpoint, the purpose of this research is to furnish the authority of the creative inheritance on the settlement of Jeol and other decorums suitable to the present. This research is consisted of 1) the study of the meaning of Jeol and 2) the hidtorical research through records. 'Jurye' is regarded as the oldest literature on the systematic explanation about Jeol and has been very often used down the ages. Jindong in 'Jurye' and Kodu in 'Karyejipram' are the same Jeol which expresses the grief in funeral rites. In 'Seonghosaseol', Abae which stands one knee is explained and investigated as the case of offense by the literature. And it is also interpreated as a Jeol with respect, while many other Jeol is to fall an both of kness, Abae is not performed generally. 'Yeki' has brief explanation about Kongsu Manner (to hold hands), Jeol between the king and minister, host and guest, Buinbae, Jeol in custom, wedding ceremony and funeral ceremony and Jeol in drinking manner. In 'Chunchukongyangjeon'. there is the explanation about Jeol of the minister who comes back after his duty to the king. 'Sunjajiphae' interprets Bae and Kyesang and informs that Kuesu is the most respectful Jeol only to the king, 'Seojeon' proves the Jeol habitually used in all kinds of ceremonies and etiquettes. 'Jeongbomunheonbigo' introduces the custom of Jeol in Shilla, Koguryo, Buyeo, Koryo eras by using literature and shows the commoness of both kneeling down generally. The result of this research has the meaning for the creation of life culture in the basis of the spirit 'Onkojisin'(reviewing the old and learning the new) by establishing the present Jeol with tradition.

In order to understand the broad outline and palaeobotanical significances, the fossil woods from the Korean Peninsula were integrated through the literature surveys. Types and diversity of them are gradually increasing from Mesozoic to Cenozoic, especially increased sharply in Cenozoic. During the Early Mesozoic, six conifer taxa belonging to four genera were described, which corresponds to about 6% of the Daedong flora. Those of the Late Mesozoic are all conifers, consisting of fifteen taxa belonging to seven genera, which corresponds to about 29% of the Nakdong flora. During the Neogene, thirty four taxa belong to sixteen families were described. Those woods mostly consist of dicotyledon and have the greatest diversity compared to other geologic eras, which corresponds to about 83% of the Janggi flora. It is inferred that such a rapid increase of the silicified wood fossils in Neogene are due to the abundant presence of dicotyledon in floral composition and of pyroclastic rocks in strata, which are appropriate for preserving wood as fossils.

Objectives: Korean medicine hospitals, since they first emerged in the early 1970s, have rapidly become a new member of the hospital population. As it was a new organizational frame for traditional medicine, we tried to analyze the changes of Korean medicine hospitals coping with institutional environment and their relative positioning in the whole health care sector. Methods: On the basis of Scott and his colleagues' identification of the three components of institutional environments, changes in organizational logics, actors, and governance of Korean medicine hospitals during the period from 1971 to 2010 were analyzed. Results: First, Similar to previous literature on institutional eras of Korean health sector, three distinct periods were characterized: the foundation of Korean medicine hospitals to consolidate the legal status(1971~1986), a rapid increase of entrepreneurial hospitals through cultural-cognitive legitimacy(1987~2001), and the reinforcement of specialization and competition(2002~present). Conclusions: Results suggested that: (1) changes in institutional environments hada heavy impact on structural and behavioral changes among Korean medicine hospitals, but the pace was slower than that of western medicine hospitals. (2) In structure, Korean medicine hospitals have positioned themselves as unofficial long-term care hospitals, focusing on chronic diseases(e.g. cerebrovascular disease). Our study demonstrated that organizational theories can provide useful framework for the analysis of Korean medicine and related policies. Indeed, one of the most important implications of this study is that understanding changes in institutional environments is important to understand the process of how members of the health care sector live, grow, change, decline and survive.
