According to the statistics revealed by Bank of Korea on March, 2007, Internet banking transactions outnumbered face-to-face banking services in Korea. Internet banking is becoming essential in every financial service sectors. For people with disabilities, Internet banking is more meaningful because they do not need to visit the bank, thereby saving inconvenient trips. Governments in many countries are working on setting standards and laws on the web accessibility for people with disabilities. Korea government enacted Korea Disability Discrimination Act in 2007. This paper examined the web accessibility compliance of Internet banking sites. Twenty one Internet banking sites were selected from the list in the Korea Federation of Banks's Web sites. We examined four major checkpoints that are considered crucial among the fourteen checkpoints in "Internet Web Contents Accessibility Guidelines" which was amended by Ministry of the information and Communication in 2005. The results showed that all of the twenty one Internet banking sites didn't meet the four major checkpoint requirements. Moreover, only one banking site satisfied alt-text requirement that is considered the most fundamental among the checkpoints.

This thesis aims at understanding Le Corbusier's architecture through study of proportion. Based on the analysis of these texts, four elements - geometry in the outline, diagonal regulation lines in the facade, arithmetic rhythm in the structure, composition in the inner space - were listed. Through these four proportional systems. ten houses of 1920's, designed by Le Corbusier were analysed. The Le Corbusier's proportional system can be classified by two different purposes ; aesthetics and utility standardization for the mass production was reflected. In the later period, the proportion system of 1920's has changed through the process of self-contradiction. But the concept of the golden section and the human scale was reflected on Modulor, which Le Corbusier created in 1940's. Therefore, Le Corbuiser's notion of proportion for harmony of architecture has consistent meaning throughout all of his works from the 1920's.

The Internet has motivated firms to participate in electronic commerce. With the development of electronic commerce, SMEs (small- and medium-sized enterprises) may be forced to use e-intermediaries in export marketing. This study aims at assessing e-intermediaries in various aspects. Empirical and theoretical studies are conducted to investigate determinants and effects of eintermediary use in export marketing. Based on resource-based view (RBV), the study develops a conceptual model that can address the question of which international competence and export performance are closely related to e-intermediary use by SMEs. Based on literature review and theoretical foundations, this study made four hypotheses. With AMOS, structural equation modeling (SEM) was used for testing four hypotheses. The empirical findings support all hypotheses. Last, this study suggests examining comprehensive internal and external factors in terms of e-intermediary use as an interesting topic for future research.

In complex waterproofing method, the stability of the joint is an important factor. The joints should not be broken for repeated movements and tensile forces. Therefore, we tried to confirm the stability of joints in newly developed joints and general joints. Repeated fatigue resistance performance tests and joint tensile strength tests were carried out on four types of joints. The fatigue resistance performance test showed no abnormality in all four types. It was confirmed that the newly developed top-down joint has higher stiffness than existing joints.

The author conducted an experiment of recording side shift of the lateral mandibular movement and analyzing the timing of the side shift on the twenty-two non-functioning side condyles. As a result, clinically useful informations were obtained. The findings were as follows: 1. On all the non-functioning side condyle path, during the first four millimeters of forward movement, the change in the rate of the mandibular side shift was observed. 2. Band E types of the mandibular side shift ,which have shown a distinct rate of immediate side shift were fifteen condyles, and C type of the mandibular side shift which has shown the greatest rate of the side shift occurs early in the first four millimeters of forward movement was seven condyles. 3. A and D types which have shown generally progressive and distributed nature were not observed.

In this Study, indicators for the evaluation of environmental amenity were determined through the investigation of the resident's consciousness in all thirty one cities and counties of Kyonggi. Also, environmental amenity that the resident feel in terms of recognition level was evaluated and based on the determined environmental indicators, environmental amenity for the physical environmental situation was evaluated. By analyzing the results, basic data for the planning of the future environmental management were prepared. The results of this study can be summarized as follows First, the developed indicators for the evaluation of environmental amenity consist of four intermediate evaluation items and fifteen individual evaluation items, and fifty four evaluation standards in total . Two to five evaluation standards were determined for the respective individual evaluation items. Second, using the developed indicators, the evaluation of environmental amenity were implemented based on both resident's consciousness and statistical data. Third, by analyzing the difference between two evaluation results, future research plan was proposed.

The effect of buoyancy orientation on turbulent channel flow has been investigated using DNS (direct numerical simulation). Grashof number is kept at 9.6 $\times 10^{5}$ while changing the orientation of the buoyancy vector to be parallel or perpendicular to the channel walls. Four study cases can be distinguished during this research namely; streamwise, wall-normal unstable stratification, wall-normal stable stratification and spanwise oriented buoyancy. The driving mean pressure gradient used in all cases is adjusted to keep mass flow rate constant while friction Reynolds number is around 150. At this Grashof number, the skin friction shows decrement in the unstable and stable stratification and increment in the other two cases. Analyses of the changes of flow structure for the four cases are presented highlighting on the mean quantities and second order statistics.

Any revision of seismic codes usually demands a higher capacity from structural members, making existing structures unsafe particularly from strength considerations. Retrofitting of capacity deficient members is very suitable for tackling such situations. This paper presents an experimental study on different retrofitting measures adopted for strengthening a series of reinforced concrete (RC) beams. Four identical RC beam specimens were casted, out of which three specimens were strengthened by different schemes (viz., bolted hot rolled flat, bolted cold-formed steel channel, and carbon fibre reinforced polymer (CFRP) laminate, respectively) on their tension face and tested under four-point monotonic loading. This study focuses on the investigation of the flexural behaviour of these retrofitted beams, observed in terms of strength and stiffness. It was concluded that all retrofitting measures improved the structural performance of these beams. However, the cost involved with each strengthening mode was proportional to the improvement in the performance achieved.

This study was done to determine the effect of antioxidants added perilla oil diet on the content of cholesterol, vitamin E, and lipid peroxide in serum and tissue of rats. Four groups of experimental diets, such none added perilla oil diet, ascorbic acid added perilla oil diet, vitamin E added perilla oil diet, EDTA added perilla oil diet were fed ad libitum to the 4 weeks white male rats of Sprague-Dawley strain. The results obtained are summarized as follow: 1) The body weight gain in all experimental diet groups was higher than the control gorup and EDTA added diet group was lower than the other experimental diet group, while food intake in vitamin E added diet group was the highest and vitamin C added diet group was the lowest in the control group. 2) Total cholesterol levels in serum of all experimental diet groups were lower than that of the control group and especially the level of total cholesterol in none added diet group and vitamin C added diet group were significantly lower than that of control group. 3) HDL-cholesterol levels of all experimental diet groups were lower than that of the control group and especially none added diet group was significantly lower than that of control group. 4) The activities of glutamic oxaloacetic transaminase (GOT) in serum of all experimental diet group except EDTA added diet group were higher than that of the control group and especially none added diet group was significanly higher than that of the control group. The activites of glutamic pyruvic transaminase (GPT) in serum of all experimental diet groups except vitamin C added group were higher than that of control group. 5) Vitamin E levels in serum of none added diet group and vitamin C added diet group were lower than that of the control group and vitamin E added diet group and EDTA added diet group were higher than that of the control group. 6) Vitamin E levels in liver of all experimental diet groups were higher than that of control group and especially none added diet group and vitamin E added diet group were significantly higher than that of the control group. 7) Lipid peroxide in serum of all experimental diet group were lower than that of control group and especially EDTA added diet group. 8) Lipid peroxide in liver and spleen of all experimental diet groups were higher than that of the control group and lipid peroxide in kidney of all experimental diet groups except EDTA added diet group were higher than that of the control group. Four these results, as vitamin C, vitamin E and EDTA added diets have an effect to lipid peroxide by antioxidants, it could be suggested that perilla oil diet has required to add antioxidant because it has not sufficient vitamin E for antioxidant and intake and overtake level of perilla oil diet should be studied to go ahead.

Purpose : To evaluate the specific radiologic findings of testicular lymphoma which will be able to differentiated from other testicular tumors. Materials and Methods : Pathologically confirmed eight cases were included in this study. All eight cases were performed ultrasonography and four cases were performed magnetic resonance image. On ultrasonography, the size, location, shape, margin, internal echogenicity, homogeneity and vascularity were evaluated. On magnetic resonance image, the shape, margin, homogeneity, signal intensity on T1- and T2-weighted images, degree and homogeneity of the contrast enhancement and contrast enhancement change on dynamic enhancement study. Results : The margin of the mass was smooth on 6 of 8 patients. Internal echogenicity of the mass lesion was hypoechoic than normal testicular parenchyme on 7 of 8 patients. Four cases were homogeneous, 3 cases were relatively homogeneous and 1 case was heterogeneous. All 8 cases showed increased vascularity. The mass lesion was iso-signal intensity on T1-weighted image and low-signal intensity on T2-weighted image. All four cases were enhanced homogeneously and mildly than enhancing normal testicular parenchyme. On dynamic enhancement study, the mass lesion is progressively enhanced with time. Conclusion : The possibility of testicular lymphoma should be considered when testicular mass was homogeneously hypoechoic and low signal intensity on T2-weighted image in old age patients.
