Many critics on William Faulkner's As I Lay Dying have read Addie Bundren as the disrupter of patriarchal power. By raising a question about the usefulness of language, which is the symbolic power of patriarchy and having an affair with the preacher Whitfield outside her wedlock, Addie directly challenges patriarchal power. From a quite different vantage point, however, we can read Addie as the faithful protector of the norm of whiteness in the South in light of the social hierarchy. As a former school teacher, Addie is from middle class before her marriage. By her marriage to Anse, who is a lower-class white, Addie has class anxiety that her social status in the stratum of whiteness could be degraded from a middle to a lower-class white, "white trash," which means that she is not white enough to be considered as the normative whiteness. Especially, Addie's anxiety increases due to the fact that her lazy husband is reluctant to work and relies on her neighbors, causing her family to be entrapped at the bottom in the stratum of whiteness. Therefore, she decides to take revenge on her husband after giving birth to her second child Darl by asking Anse to bury her dead body in her familial burial site in Jefferson. By rendering her family to suffer the hardship during her funeral procession, not only does she succeed in taking revenge on Anse on the surface, she regains her social status as a middle-class white by being buried in Jefferson fundamentally.

Fructose 1,6-bisphosphate aldolase (FBA) is important for both glycolysis and gluconeogenesis in life. Class II (zinc dependent) FBA is an attractive target for the development of antibiotics against protozoa, bacteria, and fungi, and is also widely used to produce various high-value stereoisomers in the chemical and pharmaceutical industry. In this study, the crystal structures of class II Escherichia coli FBA (EcFBA) were determined from four different crystals, with resolutions between $1.8{\AA}$ and $2.0{\AA}$. Native EcFBA structures showed two separate sites of Zn1 (interior position) and Zn2 (active site surface position) for $Zn^{2+}$ ion. Citrate and TRIS bound EcFBA structures showed $Zn^{2+}$ position exclusively at Zn2. Crystallographic snapshots of EcFBA structures with and without ligand binding proposed the rationale of metal shift at the active site, which might be a hidden mechanism to keep the trace metal cofactor $Zn^{2+}$ within EcFBA without losing it.

The programmable logic array to match the treatment technology to the soil contaminated site based on the site properties in Korea was developed. Based on the previous technology screening system of FRTR (Federal Remediation Technology Roundtable) in USA, total 9 evaluation factors indicating the site characteristics were used for the technology matching process and 8 factors among them were quantitatively weighed in the order of importance. The class interval for each evaluation factor was linearly distributed to give the weighed score and 8 scores were summed up to prioritize the treatment technology. The optimal treatment technology for a specific site was determined according to the total score acquired from 8 evaluation factors used in this technology matching process. The reliability test for the developed technology matching system was done by using information of two real cleanup sites in Korea, suggesting that this guideline will be available to determine the most effective treatment technology to cleanup the soil contaminated site and also to assist the government or the company to design a successful and cost-effective site cleanup plan in Korea.

Nakseonjae in Changdeokgung Palace was established at The King Hunjong's 13rd year (1847), the mid-19th century. It was constructed for own rests of King Hunjong and the residence of Kyungbin (king's concubines), and is showing features of upper-class houses from several points such as rustic architectural types by getting out of authoritative aspects as king's shelter space within the palace, block and floor distribution that separated spaces for men and women, simplicity in structures and styles, and non-colorful painting etc. This study aims at tracing on which architectural types did the upper-class houses within Hanyang (modern Seoul) at late Joseon Dynasty have and what was characteristics of Nakseonjae. The resemblance between Nakseonjae and the upper-class houses was very little differences from scale aspects, and floor plan shapes of Anchae (women's quarters) and Sarangchae (men's quarters) were followed basic common styles. Also, resemblance could be confirmed in the structural styles too. Characteristics of Nakseonjae are showing apparent differences from clearance compositions such as hall configuration etc. Nakseonjae was king's dwelling place, and spaces for house's collateral functions such as kitchen, stable, and warehouse etc together with shrine were unnecessary, and such places were substituted into servants' quarters for assisting the Royal family. In detailed structural styles, column's size was larger 3cm or more than the upper-class houses, and its height was higher to the degree of 30~60cm. Besides, formality as king's shelter space was raised more in decorating aspects, and Nakseonjae was implemented by getting architectural influences from Qing Dynasty of China. This study induced features of Hanyang's upper-class houses at the 19th century by supplementing distribution and space configurations at existing cases of Seoul and Gyeonggi area together with house diagrams having been collected by Gaokdohyung (site and floor plan) of Jangseogak Library, and confirmed resemblances and differences with Nakseonjae, that is, features of Nakseonjae. Through the result, this study judges a fact that architecture of Nakseonjae seemed to be affected from conveniences of upper-class houses within Hanseong, and also architectural styles and distribution types of Nakseonje would give influences to the upper-class houses.

This paper aims to introduce some useful multimedia freewares, and also support Chinese instructor with discussing how to operate them for instructional design of multimedia language learning class. For this aims, this paper consists of three parts: First, instructional design. This part is focused to what kind of instructional model to be based on, for example, Dick & Carey model, ADDIE model, ASSURE model etc. This part introduces these models, and modifies ADDIE and ASSURE model to D.D.A.I.E.S and S.S.A.U.R.E.S as 'A(nalysis)' in these model may apply to the next 'D(evelopment)' on ADDIE, 'S(elect Methods, Media and Materials)' on ASSURE in the practical Chinese class. Second, Programme: What to use. This part is focused to what kind of free software we can use. In the web site online, there are huge free softwares so we usually hesitate to select and also don't know how to operate even though selected one of them. This part, accordingly, introduces ten of useful freewares and compares each other in terms of usefulness for Chinese instructors. Third, Programme: How to use. It is of no use just to know what to use but not to know how to operate, so this part describes how to use freewares like a kind of manual in detail as far as possible. In conclusion, we hope more Chinese instructors to learn and use more useful freewares for designing the better multimedia Chinese class by this paper.

Sewon was a new type of private academy established by a class landed Confucian scholars known as sarim. During Joseon dynasty, sewon had dual functions as a shrine and a place of learning. The site plan of seowon appeared mainly two types of site plan according to the indications of the age and school. This paper was done to analyze the site plan and construction history of Simgok seowon with historical materials and excavation investigation result. Simgok seowon is dedicated to Jo Gwang-jo(1482~1519). This private Confucian academy was founded in 1605 as a small shrine, which was destroyed in 1636. Thereafter, when the shrine received a royal warrant naming as Simgok seowon in 1650, the new site for the seowon was chosen, which is currently located in Gyeonggi-do Yongin-si Sanghyeon-ri 203. Since then, buildings of Simgok seowon was constructed and repaired couple of times. Through the investigation, it was found that the site plan of Simgok seowon was originally a type of 'jeonjaehudang', that is, dormitory building between the lecture hall and the outer gate, or dormitory building is in front and lecture hall is in behind.

Fragility curves are being more significant as a useful tool for evaluating the relationship between the earthquake intensity measure and the effects of the engineering demand parameter on the buildings. In this paper, the effect of different site conditions on the vulnerability of the structures was examined through the fragility curves taking into account different strength capacities of the precast columns. Thus, typical existing single-story precast RC industrial buildings which were built in Turkey after the year 2000 were examined. The fragility curves for the three typical existing industrial structures were derived from an analytical approach by performing non-linear dynamic analyses considering three different soil conditions. The Park and Ang damage index was used in order to determine the damage level of the members. The spectral acceleration (Sa) was used as the ground motion parameter in the fragility curves. The results indicate that the fragility curves were derived for the structures vary depending on the site conditions. The damage probability of exceedance values increased from stiff site to soft site for any Sa value. This difference increases in long period in examined buildings. In addition, earthquake demand values were calculated by considering the buildings and site conditions, and the effect of the site class on the building damage was evaluated by considering the Mean Damage Ratio parameter (MDR). Achieving fragility curves and MDR curves as a function of spectral acceleration enables a quick and practical risk assessment in existing buildings.
