This paper examines the Spaghetti bowl effect that different tariffs and rules of origin in multiple FTAs have resulted in increasing the significantly additional burden for business when it comes to apply for the use of FTA preference. The wide spread of FTAs in the several years, from 2003 to 2010, has been the most important trade policy development in economically important Korea. Korea presently has 5 FTAs in effect, and made 3 additional agreements which will be expected to take effect in next year. With the study result and expecting a growing number of FTAs in Korea in a next decade, the international trading firms will face rise of transaction costs for enterprises, particularly small- and medium-sized enterprises(SMEs) to cope with multiple tariffs and rule of origins in FTAs. To help mitigate negative effects and facilitate a more SEMs to use the FTA preference, providing new computer programs system, increasing the awareness of FTA provisions, improving business participation in FTA consultations, and SME support in light of education, and financial support are needed.

The thermal behavior of Flow Pattern Defect (FPD) and Large Pit (LP) in Czochralski Silicon crystal was investigated by applying high temperature annealing ($\geq$$1100^{\circ}C$) and non-agitated Secco etching. For evaluation of the effect of LP upon device performance/yield, commercial DRAM and ASIC devices were fabricated. The results indicated that high temperature annealing generates LPs whereas it decreases FPD density drastically. However, the origins of FPD and LP seemed to be quite different by not showing any correspondence to their density and the location of LP generation and FPD extinction. By not showing any difference between the performance/yield of devices whose design rule is larger than 0.35 $\mu\textrm{m}$, LP seemed not to have detrimental effects on the performance/yield.

High quality CdTe single crystal for the solar cell fabrication was grown by vertical Bridgman method. The etch pits patterns of {111}surfaces of CdTe etched by Nakagawa solution was observed the {111} A composed of Cd atoms with typical triangle etch pits of pyramid mode. From the photoluminescence measurement on {111}A, we observed free exciton($E_x$) existing only higy quality crystal and neytral acceptor bound exciton($A^0$,X) having very strong peak intensity. Then, the full width at half maximum and binding energy of neutral acceptor bound exciton were 7 meV and 5.9 meV, respectively. By Haynes rule, an actibation energy of impurity was 59 meV. Therefore, the origins on impurity level acting as a neutral acceptor were associated Ag or Cu elements.

The purpose of this study is to find out the origin of perpetuity in the fashion design of Soma Delaunay, who was recognized as a unique designer in the 20th century. Her characteristics of fashion design appeared as dynamism in the incline of op-art using geometric pattern designed on the basis of abstract painting, color contrast between strong original colors, and repeated geometric patterns. The modern image can be explained as modernity in modern fashion and is continued in these days. The origins of modernity analyzed as follows. First, Soma Delaunay developed textile design, considering the use of clothing on the basis of scientific idea. Furthermore, she evolved traditional textile design and making process into a practical and rational way through developing new needlework technique. Second, she tried a new style through a straight silhouette in contrast to Art Nouveau style and the test and mixture of different genres. Third, she expressed the simultaneity of Orphism through the parallel structure of various colors. In particular, she used the contrast of strong and clear original colors to express a rhythm of dynamism and give visual interest through color. Finally, Soma Delaunay attempted to approach the public using clothing, furniture, and curtains with the focus on textiles. It may represent her intention to remove a gap between art and life by understanding the public and their life. As examined above, it can be sad that Soma Delaunay's scientific idea with the flow of industrialization, an open attitude not bound by a rule as an artist, an idea of Avant-garde, the comprehension of various colors and the understanding of the public. These factors lie at the bottom of her fashion design.

Apple stem grooving virus (ASGV) belongs to Capillovirus and infects pome fruits. Transmission mode of ASGV is known by grafting and mechanical inoculation into susceptible hosts, not by any other natural vectors. But we have observed the spread of ASGV in the field without mechanical inoculation or grafting. Transmission seems to be occurred from tree-to-tree and tree-to-susceptible herbaceous plants along but not across ditches in the field. In order to ascertain this possibility, various fungi were isolated and cultured from ASGV-infected plants and 69 isolates were characterized. By means of RNA dot-blot hybridization and PCR analysis, 3 isolates were sorted out for further studies. The isolates were identified to Tataromyces sp. and belonged to Phenicillium by morphological characteristics and molecular markers. As an experimental host, 10 kidney beans (Phaseolus vulgaris) were screened and Kyunggi-5 was selected for virus amplification and symptom development. Kyunggj-5 infected by fungi which seemed to carry ASGV showed the typical disease symptoms and viral coat protein genes were detected from all tested plants. To confirm the Koch's rule, fungi cultured from inoculation origins of kidney bean were grown on PDA media and re-inoculated to hosts. The fungi isolated from inoculation origins induced the typical disease symptoms on hosts. However virus free fungi did not induce any symptom on the experimental hosts. This bioassay showed that these typical symptoms were caused by virus, not fungi.

The purpose of this study was to explore clusters of married woman based on family differentiation and family rules originating from their family of origin, and to examine family strength according to clusters. The research instrument comprised of a questionnaire completed by 269 married women that investigated family differentiation and family rules based on family origins, and the comparative strength of their nuclear family. Analysis of subgroups was based on four representative categories differentiating family rule patterns. Cluster analysis demonstrated that the higher family differentiation level and lower-mid family rules level were related to greater family strength. As a subgroup, lowest levels of family strength were associated with lower family differentiation and lower family rules in all clusters. Findings supported the efficacy of a typological approach for investigation of experiences of married women based on family origin.

This paper investigates the characteristics of preservation of Korean modern architecture through Western historic preservation theories and philosophies. This research focuses on the Japanese Government-General of Korea (1926-1995) which was built in 1926 and used as the chief administrative building in Seoul (Keijo in Japanese) during the Japanese colonial period (1910-1945). After Korea was liberated from Japanese rule in 1945, this building was used until 1995 for the South Korean National Assembly, the United States Army Military Government in Korea, and the National Museum of South Korea. Although it served a variety of roles, this building was the most controversial case of historic preservation in Korean modern architecture. To analyze the peculiarities and characteristics of Korean modern architecture and its preservation, this research applied Western historic preservation theories, not exclusively from classical historic preservation theories developed by Viollet-le-Duc and John Ruskin, but also from modern historic preservation theories by Theodore H. M. Prudon, Daniel Blunstone, and Frances A. Yates. This cross-cultural and comparative study of historic preservation helps identify Korean modern architecture's characteristics. It can also be a useful reference in finding the origins of Korean modern architectural identity.
