A characteristic of new waveform, called a negative waveform, was studied during reset and address periods. IR distribution, black luminance and time delay were measured to compare the negative waveform with the conventional positive waveform. Based on the analysis of IR measurement, the negative waveform could accumulate more wall charges than the positive waveform. Also the black luminance of negative waveform was lower than that of positive waveform under the same bias and ramp-slope conditions. During address period, the discharge time lag was measured. The negative waveform was showed 0.25 us faster formative time lag and 0.1 us faster average time lag than those of positive waveform.

We study the characteristic Jacobi operator ${\ell}={\bar{R}({\cdot},{\xi}){\xi}$ (along the Reeb flow ${\xi}$) on the unit tangent sphere bundle $T_1M$ over a Riemannian manifold ($M^n$, g). We prove that if ${\ell}$ is pseudo-parallel, i.e., ${\bar{R}{\cdot}{\ell}=L{\mathcal{Q}}({\bar{g}},{\ell})$, by a non-positive function L, then M is locally flat. Moreover, when L is a constant and $n{\neq}16$, M is of constant curvature 0 or 1.

Purpose: This study was to identify the correlations between management of menopause, urinary incontinence and sexual satisfaction in climacteric women. Method: This study was conducted using a convenient sampling method in and around Jinju city, and each participant gave consent for the research. A total sample of 250 middle-aged women aged 40 to 60 years were chosen for the study, of which 157 women completed the questionnaires used for the analysis. Data was collected from Jan 1st to Mar 31st, 2004 by structured questionnaires (questionnaires for management of menopause, urinary incontinence and sexual satisfaction). Result: The characteristic variables significantly related to management of menopause were occupation and religion. The characteristic variable significantly related to urinary incontinence was age. The characteristic variables significantly related to sexual satisfaction were religion, economic status, and frequency of delivery. The relationship between management of menopause and sexual satisfaction was statistically significant with a positive correlation. Conclusion: It is hoped that the above findings will stimulate health promoting programs for climacteric women.

Let R be a domain with quotient field K and prime subring A. Then R is integral over each of its subrings having quotient field K if and only if (A, R) is a survival pair. This shows the redundancy of a condition involving going-down pairs in a earlier characterization of such rings. In characteristic 0, the domains being characterized are the rings R that are isomorphic to subrings of the ring of all algebraic integers. In positive (prime) characteristic, the domains R being characterized are of two kinds: either R = K is an algebraic field extension of A or precisely one valuation domain of K does not contain R.

This research surveys the forming process of Practical Korean Costume and its social factors and examines Hanbok reformation. The international mode of '86 Seoul Asian Games and '88 Seoul Olympic Games in the 1980's called for the modernization of Hanbok. It is necessary for us to inherit modernized Hanbok which is endowed with the traditional beauty. The purpose of this research is to develop Practical Korean Costume design for focused on functionality as well as on keeping the traditional beauty This study consist of theoretical study and positive study. Theoretical study has the esthetic characteristics(structure characteristic, formative characteristic and the characteristic of color). Grounded upon survey on brands, I have suggested designs that maintain Hanbok's superiority and functionality to fit modern life. Most of Practical Korean Costume shops could not fractionalize customer. So it need to subdivide and specialize customer and investment to improvement of design. Practical Korean Costume will have to be made to maintain dignity by using high quality materials and a coordinate goods will have to be developed.

In this paper, I examines the spatial representation of the change in the environment of the digital platform, and play the game with a focus on the spatial characteristics of a digital game. First, what is the Spatial characteristic of digital games? This section applies to a digital game "theory of Lefebvre", and the spatial representation of the practice space, divided into representational space were explored. Second, how to express dealing Is there space in the genre of adventure games? The spatial characteristics of the game medium through the Spatial characteristic of the adventure game genre that is most striking examples was analyzed whether the expression in any way. Consequently, the spatial characteristics of the digital game studies of the game as well as think a very large role in the development direction. In addition, this case analysis of the expression is the basis of this digital game that is utilized in many areas, and I am sure many possibilities to find a positive role in the game.

This paper is studied on a prevention system for electrical fire and electrical faults by using electrical temperature characteristic of PTC thermistor. The PTC thermistor has characteristic of positive resistivity temperature coefficient according to the temperature variation, which is construction of a regular square and cube demarcation with $BaTiO_3$ ceramics of positive temperature coefficient. Also PTC shows the phenomenon which is rapidly increased in the resistivity if the temperature is increased over Curie temperature point. This paper is proposed on a protective control system used with temperature sensor of PTC thermistor. The proposed prevention system will prevent electrical fires due to electric short circuit faults or overload faults. And the prevention system will solve the problems that circuit breakers to be commonly used at existing are happened frequently electrical fires and electrical disasters due to incapable operation, weak reliability and low speed response. Some experimental results of the proposed apparatus are confirmed to the validity of the analytical results.

This study aims to help revitalize the real-time online education platform market by analyzing the instructor characteristics, content characteristics, and platform characteristics of real-time online education platforms for local learners in China. A total of 670 questionnaires were collected through an online survey and an empirical analysis was conducted. As a result of the analysis, first, except for attractiveness, which is the characteristic of the instructor, professionalism and sincerity had a significant positive influence on both learning satisfaction. Second, the usefulness, abundance, and appropriateness of content characteristics had a significant positive influence on learning satisfaction. Third, except for interaction, which is a platform characteristic, technology and convenience confirmed a significant positive influence relationship on both learning satisfaction. Fourth, learning satisfaction had a significant positive effect on the intention to continue using. This study presented practical implications for real-time online education platform and future research directions.

Objective : The aim of this study was to investigate the relationship between trait anxiety and positive psychological factors. Methods : A total of 429 outpatients diagnosed with depression and/or anxiety disorders surveyed with questionnaires measuring socio-demographic, clinical, and positive psychological factors. The relationships of trait anxiety with clinical symptoms and positive psychological factors were evaluated. Results : Patients with low trait anxiety showed high optimism, gratitude, hope, spirituality and purpose in life. After adjusting age, scores of BDI and STAI-S, the results showed low trait anxiety was associated with high spirituality and purpose in life. Conclusion : The result revealed that trait anxiety had negative-relationship with spirituality and purpose in life in patients with depressive and/or anxiety disorders. Although trait anxiety was known as a general tendency which is stable, approach to trait anxiety by modulating these associated positive psychological factors would be newer approach of treatment to patients with depressive and/or anxiety disorders.
