The purpose of this study was to examine early childhood teachers' knowledge and the level of their knowledge on the contents of early childhood nutrition education. The subjects were 105 early childhood teachers and they were asked to draw a concept map. The number, characteristics and density of superordinate concepts on the contents of early childhood nutrition education were analyzed. The results were as follows: Firstly, the most frequent superordinate concept was dietary habits. Secondly, food culture was the highest average of the number of subordinate concepts. In a hierarchy, food culture was also the highest score. In specificity scores, food was the highest score. And the density ranged from 0.33 to 3.60. In conclusion, the teachers' knowledge structure on early childhood nutrition education could be regarded as parallel, not well-integrated, rather than hierarchical or well-organized. A variety of nutrition education and customized teacher training should be provided for early childhood teachers to offer early childhood nutrition education.

We examined effects of co-culture with human oviduct epithelial cells (HOEC) on the development of mouse and human embryos from early embryonic· stage to late morula or blastocyst stage (LM or B). In human, embryos were transferred and pregnancy rate was investigated. The HOEC, collected from surgically removed fallopian tube, were cultured in medium-199 supplemented with 20 % fetal cord serum (FCS). The HOEC were characterized by using immunocytochemical staining with anticytokeratin antibody and then used for cultures of mouse and human embryos. Results obtained from co-culture system were as follows. Development rate of mouse embryos was improved by co-culture system at late developmental stage (p<0.025). Human supernumerary embryos remained after transfer, unsuitable for freezing because of their poor quality, were co-cultured for 72hrs. Co-culture (78.79%) or conditioned medium (78.26%) system improved the developmemt rate, significantly, in comparision with control (11.11%)(p<0.00l). Co-cultured (85.71%) human zygotes for 24hrs showed the better development rate in comparision with control (50.00%) (p<0.01). When we transferred embryos cultured with the HOEC to patients, we obtained one pregnancy. Co-cultured human zygotes for 24hrs showed the better quality and viability for the replacement in comparision with control (p<0.01). In addition, improved pregnancy rate was obtained. Our results suggest that the co-culture system can rescue early degenerating embryos by improving early development and yield a resonable number of blastocyst for the appropriate replacement. The effect provided by cultured HOEC is not species specific for the development of embryos and it can be used to overcome in vitro blocks for the development. And also the co-culture system offers the possibility to freeze embryos at blastocyst stage which is more sucessful stage for the freezing. The HOEC monolayer may provide some stimulus via specific factor, which is unknown, to the development of embryos. Our results showed that the co-culture system with HOEC can be an alternative to conventional culture system.

This research is to reveal an aspect of costume culture interchange in the relationship of the early Chosun Dynasty, by considering the imported goods from Japan, of the trading goods derived by the trade diplomacy between the two countries in the early Korea-Japan relationship in the medieval era. The research results are as follows. A good-neighbor Policy in the early Chosun Dynasty was established by a link of a barbarian ban policy to blockade the frequent intrusion by Japanese barbarians. The exchange was the form of presenting a return present in return for a tribute to the Chosun Dynasty from the Japanese envoy, which has a polycentric characteristic. Pusanpo, Naipo, and Yumpo were designated as the open ports, which played a pivotal role in the Korea-Japan exchange. In trading goods between Korean and Japan. the imported goods from Japan to Korea were a wide variety of items primarily such as dyes, mordant, medicines, steel, spicers, etc. In particular, Somok used as a red mordant, which were intermediate goods to Southeast Asia, was the most heavily-traded items of imported goods from Japan. It had been consumed primarily as a raw material making the costume suit of the royal family and the aristocracy. The increased import of Somok was derived from a thought of preferred red color by our people. As its inflow was increased. the costumes tended to be luxurious In early Chosun Dynasty and resulted in social issues. This active trading from the early Chosun Dynasty caused from the communication of the Japanese envoy. In addition the study of the trading provided an opportunity that can glance at an aspect of the costume culture, though It was fractionary.

This study reviewed Korean food recipes and food culture included in English cookbooks issued in the United States from the 1930s to the early 1970s. In the 1930s cookbook, many types of soup were introduced to Korean food under the influence of the Tangban culture in the Joseon dynasty and a brief description of 'Sinseollo' culture. The 1940s cookbooks, introduced Korean table settings, food culture, and cooking methods depending on the use of chopsticks. In the 1950s cookbooks, Korean foods were selected to suit a Western table setting, and detailed explanations were included along with 'cheopsu' means the number of dishes served in Korean food. More diverse Korean food was introduced within its culture and origins in the 1960s cookbooks. The 1970s cookbooks explained, the characteristics of Korean culinary specialties that differentiated from oriental food. This study of Korean food and culture from Cookbooks issued in the United States from the 1930s to 1970s, where Eastern and Western multiculturalism coexist, can be used as baseline data to understand the identity of modern Korean food culture and the direction of the globalization of Korean food.

To study hotels related to early modern cultural heritage, this study has, first, attempted a historical approach through literature analysis and established an early modern hotel development history. Second, it has strived to suggest tourism industrial utilization measures by studying tourism industrial utilization cases through materials on the restoration of Daebul Hotel and interviews with related parties. Consequently, the researcher offers the following as tourism industrial revitalization measures for the restoration of early modern hotels. First, restoration plans for early modern hotels from early modern heritage in each region should be made on the basis of thorough examination of justifiability and of content development plans. Second, restoration of early modern hotels in each region requires the establishment and intent of an administrative management system by local governments. Third, restoration of early modern hotels is a thing of historical significance and value and should be promoted as a business that can contribute to revitalization of tourism and economic effects, acceleration of employment, etc., in each region. Fourth, preparation of a consistent, proactive advertisement methods regarding the restoration of early modern hotels is necessary.

To overcome the difficulties of collecting and culture of primary cell from genital tract on embryonic development, the present study was carried out to investigate the critical effect of cell lines, such as BRL and Vero cell and its conditioned medium on the development of early Korean native cattle embryos in vitro. Oocytes collected from slaughterhouse ovaries were matured in TCM199 containing FSH, estradiol-$17{\beta}$ and FBS with granulosa cell monolayer for 24 hours and then fertilized in vitro using frozen-thawed, heparin-treated spermatozoa in TALP for 30 hours. And then early embryos (1-2cell) were cultured in TCM199 containing 10% FBS with BOEC, Granulosa, BRL, Vera cell monolayers and conditioned medium for 2~3 days. Development to morulae and blastocysts were recorded, also examined the number of blastomeres presented a valuable parameter for the evaluation of embryonic development. The early cleavage rates of in vitro fertilized embryos co-cultured, there was no differences between primary cell and cell lines(p<0.05). The rate of development to the later stage, coculture of BRL cell was significantly higher than that of the primary cell(p<0.05). The rates of development to morula and blastocyst were significantly higher in vero cell than BRL, Granulosa, Oviduct epithelial cell conditioned medium. In the result of effect of serum on development of early bovine embryos, the use of media containing serum were significantly higher than the use of not containing one on development of early and later stage of embryos. The result of number of blastomeres in blastocysts, there is no differences between primary cell and cell lines. The blastocysts from coculture were higher than from conditioned medium in blastomere cells. In summary, these experments have proved that the culture system in TCM199 with BRL, Vero cell monolayers is effective on in vitro development of early bovine embryos, In addition, it is effective to development of bovine embryos that containing serum in conditioned medium, or in co-culture rather than in conditioned medium alone. The use of cell lines opponent to primary cells is effective in bovine embryo culture.

It seems that Balhae(渤海) had built up its national power through the international relationship from the early years of an establishment of a dynasty. And the envoys that were sent with the official duties dressed up the official uniform for a diplomatic courtesy. Accordingly, this study will be considered about the official uniform in the early years of the Balhae era. The system of the official uniform of Balhae was classified into two form as the starting from $739\sim742$ A.D. The official uniform of the early years of the Balhae($698\sim739$ A.D.) was based on the costume of the three Kingdoms[三國時代], that is, Yu, Go(待), Jo-u-gwan(鳥羽冠). These results were available owing to the reasons that the Balhaehad succeeded the culture of Go-gu-ryo(高句麗), which was the basis for the development of Parhae's own culture, and the most of the governing group and the ruling class in Balhaewere the drifting people from Go-gu-ryo. After that, which the 3th King Mun(文王), acrepted the Tang's culture positively, assumed the reins of government ascended the throne and the brisk exchange with Tang(唐) by the envoys and Suk-wui(宿衛) were dispatched to Tang, the official uniform of the Balhaewas transformed into the system of Tang. This system was similar to that of Tang in point of using a four colors and the items as Danryeong(團領), Bokdu.
