In this study, software products developed in the course of testing, software managers in the process of testing software test and test tools for effective learning effects perspective has been studied using the NHPP software. The finite failure nonhomogeneous Poisson process models presented and the life distribution applied exponential and log shaped type hazard function. Software error detection techniques known in advance, but influencing factors for considering the errors found automatically and learning factors, by prior experience, to find precisely the error factor setting up the testing manager are presented comparing the problem. As a result, the learning factor is greater than autonomous errors-detected factor that is generally efficient model could be confirmed. This paper, a failure data analysis of applying using time between failures and parameter estimation using maximum likelihood estimation method, after the efficiency of the data through trend analysis model selection were efficient using the mean square error and coefficient of determination.

In this study, software products developed in the course of testing, software managers in the process of testing software test and test tools for effective learning effects perspective has been studied using the NHPP software. The finite failure non-homogeneous Poisson process models presented and the life distribution applied extreme distribution which used to find the minimum (or the maximum) of a number of samples of various distributions. Software error detection techniques known in advance, but influencing factors for considering the errors found automatically and learning factors, by prior experience, to find precisely the error factor setting up the testing manager are presented comparing the problem. As a result, the learning factor is greater than automatic error that is generally efficient model could be confirmed. This paper, a numerical example of applying using time between failures and parameter estimation using maximum likelihood estimation method, after the efficiency of the data through trend analysis model selection were efficient using the mean square error.

The purpose of this study was to explore a self-diagnostic indicator for measuring a healthy family by adopting the theme of "happiness", which has surfaced as the most interesting in many academic fields recently. Though the basic concept of a healthy family may be shared by everyone, the criterion of happiness varies from one family to another. Therefore, it is desirable that the tool be made in such a way that every member of the family can check their health from a holistic perspective, rather than diagnosing health and happiness from the perspective of professionals. So, this study was aimed at diagnosing a family by using a tool named GAMMA model, so each family member can recognize problems and find the best options to solve it. This study. has a significant meaning in that it has tried to diagnose families by introducing the GAMMA model into domestic science for the first time.

English has been taught as a compulsory subject at elementary schools since 1997 starting with third graders, to sixth graders. We have seen active research on teaching methods for elementary English, but little has been done from the learners' perspective. It is very proper time for English educators to review what the elementary students think about their English classes. The purpose of the present study is as following. First, we tried to find out how the students' attitude toward and interest in English have changed over the four-year English education. Second we attempted to suggest the ways to promote the students' interests, and to increase understanding and participation in English classes. We also suggest that curriculum developers need to consider the students' lower interests and understanding in English classes as they move to higher grades, and that classroom teachers need to have a better understanding of what their students do and feel in the English classes.

Dok-Rak-Dang and Hyang-Dan, upper class houses of Chosun Dynasty on the early and mid 16th century, are generally known as specific style houses among traditional residences in Korea. Architectural singularities of these two residences are summarized as double facades, uncertain circulation, self-secluding construction, dilemmatic structure, and rotative circulation that are far from architectonic principle of that time. Characters of Deconstructionist Art, deconstruction of binary oppositions, double session, displacement without reversal, and paradox, are very similar to those of two residences both as a material phenomenon and as a metaphysical idea. Thus, this paper attempt to analyze architectural singularities of Dok-Rak-Dang and Hyang-Dan with the perspective of Deconstructionist Art Theory.

`파노라믹 영상'이라 함은 관련 있는 여러 영상들을 정합함으로써 하나의 새로운 영상으로 생성하는 것을 말하는데 흔히 '모자이크 영상' 이라고도 한다. 본 논문에서는 카메라를 통해서 데이터를 입력 받는다. 따라서 카메라 파라미터의 인식을 위해서 원근모델을 이용하는데, 프레임 사이의 불일치 측정 방법을 제시하여 불일치를 최소화 하였다. 또한 파노라믹 영상을 생성하기 위하여 고정된 참조와 시간에 따라 변하는 참조를 파노라믹 영상으로 제작하는 방법을 제시한다.

In the study, the operating mode and management system of dance troupes are aimed to analyze from the perspective of cultural and artistic management. The study focuses the Shanxi Huajin Dance Troup using case study method and provide a theoretical and practical reference for other literary communication forms in the literary industry. At the same time, the study provides a useful reference for how the cultural industry, with theatrical troupes as the main body, can operate and manage better in a "self-sufficient" market environment.

Exploding gradient is a widely known problem in training recurrent neural networks. The explosion problem has often been coped with cutting off the gradient norm by some fixed value. However, this strategy, commonly referred to norm clipping, is an ad hoc approach to attenuate the explosion. In this research, we opt to view the problem from a different perspective, the discrete-time optimal control with infinite horizon for a better understanding of the problem. Through this perspective, we fathom the region at which gradient explosion occurs. Based on the analysis, we introduce a gradient-explosion-free algorithm that keeps the training process away from the region. Numerical tests show that this algorithm is at least three times faster than the clipping strategy.

This paper examines the relationship between economic dependence and gender differences in housework in Korea. There are three explanatory alternatives for the relationship; economic rule of exchange, gender display perspective and deviant neutralization. We analysed both 2004 and 2009 time use survey data. The findings show the significant gender differences in time spent on housework that wives spend much more time on housework than husbands. However, among couples with non-normative gender roles, in some cases the more economically powerful wives spend more time on housework than breadwinner wives with weaker economic power, although such cases are rare. Rather, it is appropriate to conclude that, the more economically independent the wives, the less time they spend on housework; this is also the case for husbands. Overall, the Korean case shows what the economic exchange theory predicts. Thus, improvements in working wives' economic power will lead to gender equity in the division of housework.

Several optimization techniques have been proposed for volume ray casting, but these cannot achieve real-time frame rates. In addition, it is difficult to apply them to some applications that require perspective projection. Recently, hardware-based methods using 3D texture mapping are being used for real-time volume rendering. Although rendering speed approaches real time, the larger volumes require more swapping of volume bricks for the limited texture memory. Also, image quality deteriorates compared with that of conventional volume ray casting. In this paper, we propose a data structure for real-time volume ray casting named PERM (Precomputed dEnsity and gRadient Map). The PERM stores interpolated density and gradient vector for quantized cells. Since the information requiring time-consuming computations is stored in the PERM, our method can ensure interactive frame rates on a consumer PC platform. Our method normally produces high-quality images because it is based on conventional volume ray casting.
