Contemporary architecture as a text holds two attitudes corresponding to structuralism and post-structuralism. The former is the text of structuralism explained as its internal relations, in other words its structure. This attitude underlines internal structural analysis of its text that intercepts all the relations to its receptionists. The latter is the text of post-structuralism that emphasizes its receptionists and its contexts. What this attitude retains is the fact that an interpretation of an architectural text is an instance of event. Because the event is characterized by openings, possibilities and indeterminacies, its meaning is temporal and sliding. Therefore, this paper proposes the architectural text as the dialectic of both attitudes in terms of Paul Ricoeur's interpretation theory, "the live metaphor". The text as "the live metaphor" implies the "threefold mimesis" that indicates prefiguration(mimesisⅠ), configuration(mimesisⅡ), refiguration(mimesisⅢ). Therefore, this paper attempts to interpret an architectural texts as "the threefold mimesis" to suggest a positive direction for contemporary architecture to pursue.

The objective of this research work is to investigate into static characteristics of ISB panels with the pyramidal structure as a internally structured material. In order to investigate the behavior of material deformation and frracture characteristics, several tensile tests have been carried out for the ISB panel and skin sheet. Through the results of the experiments, the mechanical properties of ISB panel and skin sheet and fracture characteristics have been obtained. In addition, the mechaical properties of the ISB panel have been compared with that of the skin sheet by the view point of a specific modulus, a specific yield strength and a specific strength. From the results of the comparision, it has been shown that the ISB panel has an excellent static characteristics.

The sulfidation reaction of calcium carbonate to remove H2S were investigated. Expecially, the effect of polymorphs of calcium carbonate and reaction temperature on the sulfur capture were determined. It was found that calcination reaction of calcium carbonate were influenced by polymorphs of calcium carbonate. The calcination temperatures of aragonite were lower than those of other calcium carbonates. For the sulfidation of calcite with H2S, the effect of reaction temperature on the sulfur capture were not found. But in caes of vaterite and aragonite, the reaction temperature were found to have a significant effect on the sulfidation reaction. From in these results, optimum temperatures of sulfidation reaction using vaterite and aragonite were determined at 800∼850℃ and 750℃, respectively.

Background : Wild-cultivated P. ginseng (WCG) is a specific ginseng in Korea which depends on artificial forest growth method. To obtain a WCG which is similar to wild ginseng (WG), this method usually performed in a mountain using seeds or seedlings of cultivated ginseng (CG) and WG. Recently, very high price of WCG caused the problem that Panax notoginseng or Panax quinquefolium are sold as WCG in Korean market. This is concerned as a serious problem to consumers. In this study, we tried to develop a method to discriminate WCG, CG or WG using simple sequence repeat (SSR) markers and phylogenetic analysis. Methods and Results : WCG samples (3, 5, or 6-years old) were collected in Hoengseong, Gangwondo. DNA extraction was performed using CTAB method. SSR markers were collected from the published papers. After test PCR using the markers, one of the primer pair was labeled with fluorescence dye (FAM, NED, PET, or VIC) and Gene Scan analysis were performed. NTsys-PC program was used for the phylogenetic analysis of the data. Eight SSR markers were collected from the published literature and used for the analysis. From the 8 tested SSR markers, 7 SSR markers showed polymorphism between varieties. GenScan analysis were performed using the selected SSR markers to analyze the phylogenetic relationship of WCG. Conclusion : Phylogenetic analysis showed the relationship between WCG and P. ginseng cultivars and the seven SSR markers used in this study are able to distinguish Wild-cultivated P. ginseng.

Background : Codonopsis is a flowering plants belong to the family Campanulaceae, and has many kinds of medicinal properties. As currently recognized, two other groups, Campanumoea and Leptocodon, are included in the Codonopsis. The enlarged genus Codonopsis is distributed in Eastern, Southern, Central, and Southeastern Asia. C. lanceolata, C. clematidea and C. pilosula has many kinds of medicinal properties and this plants are used as medicinal and edible plants. C. ovata and C. mollis are distributed in Pakistan Kashmir and Himalaya mountains at an altitude of about 3,000 m, and flowers bloom in July to August. Methods and Results : In this study, we analyzed the genetic diversity of 5 Codonopsis species using 8 SSR markers base on C. lancelolata genomic sequences. Samples were obtained from fresh leaves of 5 plants from each species and genomic DNA was extracted using CTAB method. PCR was performed in total 20μl reaction volume containing 20 ng of DNA template and 5 pmole of primers. PCR conditions composed pre-denaturation at 95℃ for 5 min, then 35 cycles of 95°C for 30 sec, 60°C for 30 sec and 72°C for 30 sec, and a final extension at 72℃ for 30 min. The amplified band sizes ranged from 74 to 301 bp and clearly showed single or doble bands in eletrophoresis. From the phylogenetic analysis, C. lanceolata was grouped together, but the others were not grouped together according to the species. Conclusion : We concluded that C. lanceolata cultivated in Korea is different from the other species, and the eight SSR markers used in this study are able to distinguish C. lanceolata from the other species.
