Sneak current is one of the main bottlenecks for dense crossbar array resistive random access memory. This study reports highly non-linear resistive switching characteristic from Ce0.9Y0.1O2/ TiO2 bi-layer (1S/1R device) structure, fabricated by photochemical metal-organic deposition, as a solution for sneak current issue. Ce0.9Y0.1O2 material, possessing oxygen vacancies, was used as a potential barrier as well as oxygen reservoir which rectified the current of low resistance state without an electrical breakdown in 1S/1R device. TiO2 was adopted for resistive switching property, and TiO2 layer having mixed phase (anatase and brookite) showed typical diode switching behavior. The photochemical reaction of photochemical metal-organic deposition process and phase formation were monitored and established using by Fourier-transform infrared spectroscopy and X-ray diffraction, respectively. The 1S/1R device showed highly non-linear resistive switching characteristic, large on/ off ratio of above three orders of magnitude with low operating current.

Dance is the art form which is expressed One's thought and feelings through the body. for the artistic goa, dancers have to train their body scientifically and efficiently. If dancers practice economically, they can invest their energy and time in choreography or their new pieces along with aesthetic elements. Motor learning theory is regarded as an efficient method of body training. Yet many dance teachers have not believed that this method is appropriate to their dance class, so they depend on customary way of teaching. In this point of view, it is necessary for efficiency of dance lessons to review the researchs of dance used motor learning theory.

온도하중이 작용할 때 복합재료 하니콤 샌드위치 쉘 구조물의 거동을 파악하기 위해서 3차원 응축쉘 이론 그리고 일차전단 변형이론에 입각한 유한요소 해석이 수행되었다. 본 연구에서는 하니콤을 탄성보강재로 가정하여 온도가 증가함에 따라 하니콤과 적층쉘 사이에서 발생하는 분리현상을 규명하였다. 이러한 파손현상은 적층각도와 적층쉘 두께이 따라 다르게 나타났다. 준등방성 그리고 직교이방성 보다도 angle-ply 적층순서에서 파손이 많이 발생하였고 또한 적층쉘의 두께가 증가함에 따라 파손현상이 많이 발생하였다. Finite element analysis based on 3-D degenerated shell theory and first shear deformation theory was peformed to investigate the behavior of composite and honeycomb sandwich shell structures under thermal loading. In this study, the honeycomb was regarded as an elastic foundation and delamination phenomenon occurring between the laminated shell and the honeycomb was examined as temperature increases. The results shows that the delamination depends on lay-up angle and thickness in the composite shell. A lot of failure was occurred for angle-ply stacking sequence rather than for quasi-isotropic and cross-ply stacking sequences and a lot of failure was occurred as the thickness of the composite shell increases.

In this study, we investigate the transition of studies in the history of the Eastern costume every 5 years from 1959 to 1998 by sorting the researches into 8 classes in accordance with their topics, in order to grasp earlier and current trends in the discipline and seek a desirable direction to future research. The results of this study are summarized as follows. 1. Research papers in costume are published steadily since 1970, but it appears that the quantity of papers has increased since 1990. Master's theses make the majority of the total researches, occupying 44.8%. 20.4% of the papers appear in college periodicals or else, and 19.6% in Journal of the Korean Society of Costume. The rests are 4.5% in Journal of the Korean society of Clothing and Textiles, 3.7 % in Journal of Korean economic association, and 2.1% in Research Journal of the Culture in order. 2. Based on the classification of the topics of the papers, we have loamed that studies in materials such as patterns, textile, and colors occupy 19.5% making themselves the majority. Other topics are presented in similar frequency. 3. The most frequent topic in Men's costume is the study on Simuy, a Korean traditional jacket and Topho, a Korean traditional coat. The researches in Men's costume, focusing on historical changes, morphology, and colors, are generally performed in bibliographic historical methodology or through analyses of archaeological materials such as relics and paintings. Some papers present ways of draft from the viewpoint of clothing construction. And others include studies on variations of life emotion reflected in local properties and costume and the comparative study of the aspects of costume appeared in Confucian books and I-Ching (易經). 4. The majority of researches on Women's costume are concerned with the Korean traditional jacket Chogori, in which the focus is put on the form of Chogori and some other details. Then, the Korean traditional dress Chima-Chogori, ceremonial dresses, and the Buddhist costume are major research subjects in Women's costume in order. They analyze types and forms of the above mentioned clothes, and hence characterize contemporary aesthetic senses to corroborate the cultural inherence and beauty of the Korean traditional costume. 5. Researches on accessories, in general, concentrate on the diversity of the sorts of them, but lack enough varieties and independence in that they tend to only review the earlier work. Therefore, they need be more diverse and varied in subjects. Nonetheless, it has been found from the papers on accessories that the accessory is not so much a part of costume as an independent object of the discipline. 6. Of the subjects of Studies on materials such as patterns, textile, and colors, the pattern is the most prominent, and the researches on the pattern applied to design and the comparison with other nations' patterns has been increasing, from which we have learned that those researches will be important references in future research. In the case of textile, much work on that in Corye, a Dark Age in the field of costume study has been presented currently, which seems to signify a new breakthrough should be open. 7. Most papers on military and police uniforms have to do with history of changes based on bibliographic data, and investigations into dancing clothes, musicians' costume, and the shamanist costume are also mainly concerned with changes or systems of costume. On the other hand, studies on Kisaeng' Clothes discuss the Chosun Kisaeng's Costume and idiosyncrasies of their status. 8. About a half of papers on archaeological costume and paintings deal with exhumed clothes and textile and record paintings, from which we can tell that the researches in these topics take part in the positivistic study of the history of costume. 9. In the field of the comparative study of costume, researchers have most frequently compared the Korean costume with the Chinese costume, especially concentrating on clothes rather than on ornaments and accessories. On the other hand, it is expected that more interest should be taken in the Japanese costume, because it is not sufficiently investigated in comparison with the Chinese costume. Moreover, it is desirable to extend research interest to countries other than those in the Northeastern Asia since the tendency of the discipline has been to give more attention to the Northeastern Asia than other areas. Needless to say, the comparative study requires the researchers to have enough knowledge of historical backgrounds and local characteristics of other countries. 10. Researches on the costume in the enlightening period and the post-independence era are different than those on other periods' costume in that they are generally interested in the change of costume and the factors of the change.

The purpose of this study is to assess the effects of the separation of prescribing and dispensing in Korea and to find how civilians' usage behaviors on medical institutes such as hospital, clinics, drugstore, and community health center are changed due to the policy. To examine the differences of usage behaviors, this study used a before-after design. Using self-administered questionnaires, this study performed survey from June 26 to August 1, 2000. Chi-square test and generalized logit model was utilized in each observation period. Based on the results of each observation period, this study evaluated the effects of the policy. On the basic finings, most civilians did not agree to the separation policy regardless of both observation periods. However, after the separation, civilians' behaviors seemed to be modified as the policy maker had intended. Most of civilians purchased their drugs from pharmacists after receiving physicians' prescriptions. Specifically, males and elder persons had the exactly same behaviors as the intended utilization behaviors. All study subjects agreed to the basic purpose of the policy for the purpose of the reduction of drug abuse and misuses. The implications of this study are two fold: First, how civilians' short-term inconvenience caused by the policy should be alleviated without interrupting well-established usage patterns. Second, a special attention to the elderly is needed.

Imagery, called visualization, mental practice, mental rehearsal is a technique that has gained considerable attention in sports and dance in recent years because it is thought to enhance skill performance. In this study, theoretical interpretations of the imagery process and factors influencing imagery are reviewed for further study of imagery. The mechanisms that mediate cognition, imagery and motor movement remain mostly unknown. To gain more academic respect, the research on imagery must use better methodologies and attempt theorizing. In dance, imagery has been used for communication of movement's meaning, inspiration for creation, exprience of movements's effort. So it is necessary for more efficient dance class to study on cues and sources of imagery which must be sophyscated for levels of ability, kinds of movements and class.

Robust camera parameters estimation

김태은,김상훈 남서울대학교 2009 남서울대학교 논문집 Vol.15 No.2

In this paper, we propose a new camera calibration method for the 3D-based image synthesis and 3D reconstruction. We improve the problem as changing the principle point for obtaining the linear equation. According to the error rate, we adapt the non-linear method that minimizes the intrinsic parameters. Namely, it minimizes the intrinsic parameters error with maintaining the computational conciseness. As a result, we can find optimized camera intrinsic parameters and adapt to image synthesis and reconstruction. Keywords : Camera Calibration, 3D-based image synthesis, 3D Reconstruction. 본 논문에서는, 우리는 synthesis이미지를 이용한 새로운 카메라 캘리브레이션 측정 방법을 제시한다. 우리는 선형 방정식을 얻기위한 기본적인 포인터를 바꾸기로 개선한다. 오류율에 따르면, 우리는 본질적인 매개변수를 극소화하는 비선형 방법을 적용하였다. 그것은 컴퓨터 간결함 유지를 가진 본질적인 매개변수 과실을 극소화한다. 그 결과로, 우리는 예상한 사진기 가장중요한 매개변수를 찾아내고 3D재구성에 적용이 가능하였다.
