In this study, we focus on Ca contaminant which affects on the roughness Si substrate after thermal process. The initial Si substrates were contaminated intentionally by using a standard Ca solution. The contamination levels of Ca impurity were measured by TXRF and the chemical composition of that was analyzed by AES. Then we gre the thermal oxide to investigate the effect of Ca contaminants. The microroughness of the Si surface, the thermal oxide surface, and the surface after removing the thermal oxide were measured to examine the electrical characteristics. The initial substrates that were contaminated with the standard solution of Ca exhibited the contamination levels of 10\ulcorner~10\ulcorneratoms/$\textrm{cm}^2$ which was measured by TXRF. The Ca contaminants were detected by AES and exhibited the peaks of Ca, SI, C and O.After intentional contamination, the surface microroughness of this initial substrate was increased from $1.5\AA$ to 4$\AA$ as contamination levels became higher. The microroughness of the thermal oxide surfaces of both contaminated and bare Si substrates exhibits similar values. But the microroughness of the contaminated$ Si/SiO_2$ interface was increased as contamination increased. The thermal oxide of contaminated substrate exhibited the small minority carrier diffusion length, low breakdown voltage, and slightly high leakage current.

Due to increasing awareness about the risk which will be caused by fast aging of population, the importance of aging friendly environment including housing has been paid much attention both individually and socially. In this regard, recently, in Korea, diverse elderly living facilities have increased in its number. Because of little experience, however, there have not been enough holistic understanding about aging friendly housing. Accordingly, most previous literature which introduced elderly housing to Korean society have translated differently, thereby caused more confusion. To facilitate communication about aging friendly housing, clear and consistent definition of its type and comprehensive range needs to be delineated. The purpose of this study is to classify various elderly housing alternatives in architecturally understandable way. This study was proceeded by content analysis of existing literature on elderly housing environment. A comprehensive review on the concept and existing classification of elderly housing was done prior to main analysis of translated Korean words. After classifying the Korean words of definition, systematic classification which focused on two important criteria of determining physical characteristics, such as space sharing degree and intentional plannedness was delineated and suggested. This research shows the first step toward the theoretical foundation for elderly housing classification.

The human nose is located in the center of the face and it's cosmetic importance is high. The contour of the nasal dorsum and side walls play a major role in the shaping of the nose, and even a slight distortion may results in significant variance of the human facies. However, in the case of patients with wide nasal bone, augmention rhinoplasty can make nasal planes look wide, resulting in bulbous appearing noses or lateral borders of the nasal implant may be visible after the surgery making the final cosmetic results unsatisfactory. To solve such problems, from march, 1999 to march, 2004, the authors have performed augmention rhinoplasty in 36 patients. The cause of operations were as follows: flat nose 20, hump nose 5, deviated nose 4, secondary rhinoplasty 7. Paramedian osteotomy was performed at a distance that was the same as the width of the implant from the midline(5 mm + 5 mm). To prevent it from connecting to the roof at the lateral osteotomy line, intentional green stick fracture of the roof was performed. Agumentation rhinoplasty was done with either Silicone or Gortex and ear cartilage as a supplement. The follow up period was 2 weeks to 13 months with an average of 5.5 months. There were no infections and postoperative bleeding. As a result, the nose was augmented higher and narrower than before which we and the patient both found highly satisfactory.

PURPOSES : Traffic accidents and damage due to speeding should be recognized as a problem which harms society and the economy as well as the parties to the accidents. It is time to seek more detailed and concrete customized alternatives than the existing policies for the prevention of traffic accidents. METHODS: In this study, we identified the characteristics driver behavior and psychological factors that lead to speeding, and a study was carried out to verify the causality models developed from the factors we identified. RESULTS : Driving behavior variables have a significant effect on speeding behaviors in order of Lapse, Violation, and Mistake. And the violation which is defined as intentional violation showed the result which supports the research hypothesis as it has the significant effect on speeding intention and behaviors. CONCLUSIONS: The result of this study can be utilized to develop educational problems concerning speeding and previous response with the main objective of eliminating speeding driver behavior.

The pentacyclic triterpenoid ursolic acid (UA) and its isomer oleanolic acid (OA) are ubiquitous in food and plant medicine, and thus are easily exposed to the population through natural contact or intentional use. Although they have diverse health benefits, reported cardiovascular protective activity is contentious. In this study, the effect of UA and OA on platelet aggregation was examined on the basis that alteration of platelet activity is a potential process contributing to cardiovascular events. Treatment of UA enhanced platelet aggregation induced by thrombin or ADP, which was concentration-dependent in a range of $5-50{\mu}M$. Quite comparable results were obtained with OA, in which OA-treated platelets also exhibited an exaggerated response to either thrombin or ADP. UA treatment potentiated aggregation of whole blood, while OA failed to increase aggregation by thrombin. UA and OA did not affect plasma coagulation assessed by measuring prothrombin time and activated partial thromboplastin time. These results indicate that both UA and OA are capable of making platelets susceptible to aggregatory stimuli, and platelets rather than clotting factors are the primary target of them in proaggregatory activity. These compounds need to be used with caution, especially in the population with a predisposition to cardiovascular events.

The aim of this study is to find out the symbol of clothing decorations in Elsa Schiaparalli's design works and there are four major points due to the aim of this study. Firstly, a fantasy is represented through Surrealistic Arts which creates mysterious, secrete, and surprising spirits. In Surrealistic Arts, the fashion of schiaparelli demonstrates a fantasy spirit by using the methods like metaphor, transformation, and re-positioning. Secondly, In Surrealistic paintings, normally double image or different image from symbol immanent were expressed. However, Elsa Schiaparelli used double and multi-image decorations instead that has well-organized formative effect. The mixture of double images can be separated as symbolic mixture, design mixture and expressive mixture. Thirdly, the body parts has represented symbolism and sensuality in Surrealism Arts. Elsa Schiaparelli has demonstrated the expression of modern clothing as passionate, desirable, and powerful. This is the reason why her designs were absolutely different from the previous sihouette-focused clothing. Fourth, there are lots of intentional decoration that are different from actual images, such as transformation, exaggeration, minimization and repettion, as well as, re-location, re-arrangement, line-up arrangement, collage and odd materials.

Sn doped $In_2O_3$ (ITO) and ITO/Ni/ITO (INI) multilayer films were deposited on the glass substrates with a reactive magnetron sputtering system without intentional substrate heating and then the influence of the Ni interlayer on the methanol gas sensitivity of ITO and INI film sensors were investigated. Although both ITO and INI film sensors have the same thickness of 100 nm, INI sensors have a sandwich structure of ITO 50 nm/Ni 5 nm/ITO 45 nm. The changes in the gas sensitivity of the film sensors caused by methanol gas ranging from 100 to 1000 ppm were measured. It is observed that the INI film sensors show the higher sensitivity than that of the ITO single layer sensors. Finally, it can be concluded that the INI film sensor have the potential to be used as improved methanol gas sensors.

In this work, Ga doped ZnO (GZO) films were prepared by radio frequency (RF) magnetron sputtering without intentional substrate heating on glass substrate and then the effect of the intense electron irradiation on structural and electrical properties and the NOx gas sensitivity were investigated. Although as deposited GZO films showed a diffraction peak for ZnO (002) in the XRD pattern, GZO films that electron irradiated at electron energy of 900 eV showed the higher intense diffraction peaks than that of the as deposited GZO films. The electrical property of the films are also influenced with electron's energy. As deposited GZO films showed the three times higher resistivity than that of the films irradiated at 900 eV In addition, the sensitivity for NOx gas is also increased with electron irradiation energy and the film sensor showed the proportionally increased gas sensitivity with NOx concentration. This approach is promising in gaining improvement in the performance of thin film gas sensors used for the detection of hazard gas phase.

These days, public attention is being directed to the design processes by which a final outcome can be produced to achieve its goal according to the logical plans, as it is hard to address recent problems in design by the existing intuitive way due to the paradigm shift of design. Thus, this study aims to suggest creative fashion design processes to create a product as a final outcome by intentional and systematic processes. This study showed that design is considered as comprehensive problem solving processes, and it proposes framework of processes by integrating processes of industrial design and fashion design. In addition, this study classified creativity development methods that can be implemented to fashion design into promotion of ideas, breaking out of stereotypes, and extension of search areas. These creativity development methods can be applied to fashion design processes in order to make plans and strategies systematically and help you to choose the best ways to solve problems by processes.
