The purpose of this research is to find out how the Chinese Bronze Epigraphy has developed and how it has influenced the Chinese Academic field. The Chinese Bronze Epigraphy started from the Han dynasty, however it didn't reach the professional academic stage. After the Song Dynasty it started to be studied in full scale. Therefore, it is reasonable to see that the start of the study of bronze was from the Song dynasty. In the Qing Dynasty, the study in Epigraphy was extended on again. ShuoWenJieZi that was written by XuShen in the Han Dynasty. KaoGuTuShiWen that was written by $L{\check{u}}DaLin$ in the Song Dynasty. ShuoWenGuZhouBu that was written by WuDaCheng in the Qing Dynasty. JinWenBian that was written by RongGeng in the Republican era. This thesis examines the contents of ShuoWenGuZhouBu and JinWenBian and then synthetically compares and analyzes them. The conclusion of this study is as follows. It cannot be denied that ShuoWenJieZi and KaoGuTuShiWen significantly affected the birth of ShuoWenGuZhouBu and JinWenBian.

In spite of a few numbers of Hyangga that is handed down today, Hyangga has diverse and abundant contents. So it is possible to survey Hyangga as a journey literature of the middle age. On this purpose we can inquire into the Hwarangs' group journey, because the Hwarang was one of the main enjoying group of Hyangga. Hwarangs' group journey shows many aspects. They made a journey for the public purpose like a tour of inspection of people's daily life and the fortresses of the country's peripheral areas. Also, they made a journey for personal purposes like enjoying the attractive view of the mountains and rivers or seeking pretty girls outside of the palace. On these journeys, Hwarang made and enjoyed Hyanggas. Among Hyanggas that remains today, Hyeseongga and Cheoyongga have a direct relation to Hwarang's journey. Hyeseongga was made to eliminate the calamities that occurred at the time of the start of a journey. It is expressed in this poem that Hwarang could take a peaceful trip with the condition that the celestial objects shed light on the earth path. As such, the trip becomes a sacred ceremony. Cheoyongga reflects the fact that the foreigner Cheoyong became Hwarang and toured the streets of Seorabeol, the capital of Shilla. The Cheoyong's bitterness of broken love is expressed in this poem. SongSadahamga and MoJukjirangga come under a broad category of Hwarang's journey literature. SongSadahamga is a farewell poem for Hwarang who leaves to fight on the battlefield. It was universal to make a journey for the fighting of a battle in Shilla period, so many Hyanggas would be made under those situations. MoJukjirangga has the content of Hwarang's trip for saving his follower who was taken by another senior. It expresses the intimate relationship between Hwarang and the follower. Though the words of the song have not been remained, Hyeongeumpogok, Daedogok, and Mungungok were created on the way of Hwarang's journey. These seem to be a series poems which have the proper characteristic features of the Hwarang's journey literature. In these poems, the king's open mind and liberal political views are reflected. In short, Hwarang created and enjoyed Hyanggas on the way of their journey, so Hyangga has the features of journey literature in Korean middle ages.

Purpose: The purpose of this study was to identify social support and health status based on characteristics of leisure activity in middle-aged women. Methods: Participants were 148 middle-aged women living in the capital area. Data were collected through self-report questionnaires which were constructed to include leisure activity characteristics, social support and Brodman's CMI. Data were analyzed using t-test, and ANOVA, with SPSS/WIN 14.0. Results: Social support was different depending on leisure type, leisure partner, length of participation in present activity, regularity, and motivation to start activity. Health status was different depending on the length of participation in present activity, and regularity. Conclusion: Because social support and health status depend on characteristics of leisure activity, further study in nursing one how to resolve the physical, psychological, social and health problems that middle-aged women might experience through various leisure activities.

Telomerase reverse transcriptase (TERT) is an enzymatic ribonucleoprotein that prolongs the replicative life span of cells by maintaining protective structures at the ends of eukaryotic chromosomes. Telomerase activity is highly up-regulated in 85-90% of human cancers, and is predominately regulated by hTERT expression. In contrast, most normal somatic tissues in humans express low or undetectable levels of telomerase activity. This expression profile identifies TERT as a potential anticancer target. By using an RNA mapping strategy based on a trans-splicing ribozyme library, we identified the regions of mouse TERT (mTERT) RNA that were accessible to ribozymes. We found that particularly accessible sites were present downstream of the AUG start codon. This mTERTspecific ribozyme will be useful for validation of the RNA replacement as cancer gene therapy approach in mouse model with syngeneic tumors.

This paper describes the experiments for investigating the effects of thermal stability of several commercial carpet mate materials. The melting point and thermal decomposition temperature was measured by means of a differential scanning calorimeter(DSC) in air condition. The DSC data and burning test results of nylon bulked continuous filament(N-BCF) yarn 100%, nylon(NY), polypropylene(PP), and a new material named polytrimethyleneterephthalate(PTT) were analysed to obtain the effect on their thermal stability. Conclusively, we observed that PTT and PP were approximately $380^{\circ}C$ and $240^{\circ}C$ to start the thermal decomposition, respectively. In other words, PTT is thermally the most stable material for carpet manufacturing.
