The purpose of this study was to examine the effects of children's daily stress and employed mothers' nurturing attitude on children's problem behavior, as well as the mediating role of employed mothers' nurturing attitude. 160 children (aged 3-6, in city "D") and their mothers participated in this study. The SPSS 18.0 program was used to conduct a regression analysis to examine the correlation between the children's daily stress, their problem behavior and the employed mothers' nurturing attitude, depending on the gender of the children. The results were as follows : First, in the case of the boys, their aggression and attention have effects on their coercive attitude, and their anxiety and depression have effects of decreasing magnitude on their logical attitude, blaming / offensive stress and pride-hurt stress in that order. Secondly, in the case of the girls, their aggression has effects on their coercive attitude, and their attention has effects of decreasing magnitude on their anxiety / frustration stress and coercive logical attitude in that order. On the other hand, their anxiety / depression have effects of decreasing magnitude on their accused/offensive stress and coercive attitude in that order. Third, the employed mothers' nurturing attitude had mediating effects between the children's daily stress and their problem behavior. However, no such mediating effects were observed in the case of the boys. Therefore, the mothers tend to foster complementary and logical parenting, rather than coercive or negligent parenting. It is thought that children need to reduce their stress levels in everyday life (in order to?) reduce their problems.

The purpose of this study was to investigate the effect of the individual differences in cognitive processes on paragraph comprehension. To do so, the lexical decision task and the pattern comparison task were used to measure the low-level cognitive processes. Digit span task was used to test the phonological loop capacity. The individual differences of the central executive processing capacity were measured by operational span task. Reading span task was used to test the working memory capacity related with the sentence processing. Reading times and accuracies of the logically valid inferences and logically void inferences were tested to measure the high-level cognitive processes. Reading times and accuracies for the target sentences with and without prior explicit causal sentence were measured to test individuals' paragraph comprehension abilities. The results showed that the speed of the low-level cognitive processes was related with the speed of the high-level cognitive processes. Also, the accuracy of the low-level cognitive processes was related with the accuracy of the high-level cognitive processes while there was no significant correlation between the speed and the accuracy in any measures of the cognitive processes. Working memory capacity was related with the accuracy of the cognitive processes while it was not significantly correlated with the speed of the cognitive processes. Most importantly, the speed of low-level cognitive processes significantly affected the speed of the paragraph comprehension while the working memory capacity and the high-level cognitive processes had influences on the accuracies of the paragraph comprehension. The speed of the paragraph comprehension had no influence on the accuracies of the paragraph comprehension.

Our study is composed of Arduino robot assembly, board connecting and collaborative programming learning, and it is to evaluate their effect on improving secondary mathematics-science gifted students' convergence capability. Research results show that interpersonal skills, information-scientific creativity and integrative thinking disposition are improved. Further, by analyzing the relationship between the sub-elements of each thinking element, persistence and imagination for solving problems, interest of scientific information, openness, sense of adventure, a logical attitude, communication, productive skepticism and so on are extracted as important factors in convergence learning. Thus, as the result of our study, we know that gifted students conducted various thinking activities in their learning process to solve the problem, and it can be seen that convergence competencies are also improved significantly.

People are exposed to various media. After the Digital Revolution, quantitative expansion of the media is at a rapid pace. Because of the expansion of the media, advertising needs efforts that induce the audiences' reaction. Rhetorical devices are used as the efforts. This study noted the visual paradox of rhetorical devices because it is an effective representation device that induced audiences' reaction by deliberate contradiction and ambiguity. This study has defined the visual paradox based on define and classification of paradox in logic. This study also tried to reveal the relationship between images and text for signification by metalanguage because it is important to the visual paradox in advertising. And analyzed cases of Volkswagen ads to prove the research process. Finally identified that images and text interact to create a new meaning.

GPS(Global Positioning System)is a satellite-based navigation system that we can survey where we are, anywhere and anytime. In this paper, delay-lock loop of the receiver which detects the navigation data is theoretically analyzed, and designed using the digital logic circuit. Also logic operations for the synchronization are analyzed. The designed system consists of the correlator which correlates the received C/A code and the generated C/A code in the receiver, the C/A code generator which generates C/A code of selected satellite, and the direct digital clock syntheizer which generates the clock of the C/A code generator to control the C/A code phase and clock rate. From the analyses results of the proposed digital delay-lock loop system, the system has the detection propertied over 90% when its input signal power is above-113.98dB. The influence of input signal variation of digital delay loop, which is the input of A/D converter, is investigated and the performance is analyzed with the variation of threshold level via the computer simulation. The logic simulation results show that the designed system detects precisely the GPS navigation data.

The touch screen phone launched domestically in Korea, unlike the existing plane UI, it applied a cubic shape of 3D UI which provides three dimensional solid graphic. This study proposes to examine the correlation between the users' experience of 3D GUI, which were made by two different companies, and the brand. From this point of view, this study sets up a hypothesis about intimate correlation between individual differentiated brand and the user experience. Base on that, a model was designed. This study measured the satisfaction of user experience through the disclosure and non-disclosure of brand, focusing on 3D GUI cases which were launched so far, and it demonstrated that there was a clear difference in the degree of satisfaction. Through this examine, a brand was confirmed as one of the important element of user experience in using the 3D GUI that was launched competitively by companies. Therefore, the result of this study suggest that the designers need to establish strategies that make the brand as the core subject of design during the process of manufacturing product and service.

This dissertation discusses the formulation of a nonlinear storytelling board that preserves the contextual perspective of characters. Storytelling encompasses the director's creative intention by leveraging the interaction of various elements to construct a logical narrative that explores cause and effect. Its primary objective is to enhance viewers' empathy. Consequently, there is a pressing need for comprehensive research on differentiating storytelling from storyboarding. Moreover, the integrated approach to storytelling and storyboarding holds scholarly value in understanding the process of narrative composition and visualization. Thus, a study proposes a method for constructing nonlinear storytelling boards considering the discrete camera perspective and contextual scene continuity, ultimately contributing to visual complexity and correlation comprehension. This approach enables a careful and simultaneous consideration of the correlations that deepen cognition, including the physical, emotional, and event rhythms mentioned in Karen Perlman's theory.

In order to offer the service information of high-quality, we should develop the software of high-Quality. We need the united estimate method, because existing developed quality measurements individually measure attributes using the different viewpoint. Therefor, this paper propose the model that able to include many method of measurements. Our model selects the ratio scales and calculates the relative significance of them by using rough logic. Then, in order to measure the quality of module, it integrates the significance of scales and the measured value of them by using fuzzy integral. Finally, we analyze the correlation between the existing scales with our measurement and validate our model through statistical technique.

We propose a statistical test for the nonlinear combiner logics which are usually combined with two maximal Linear Feedback Shift Registers and generate pseudorandom bit sequences. This test uses the mutual information between the output and set of inputs which will be a random variable and its distribution is obeyed to an approximate $\{chi}^2$ -distribution. We adopt this statistic to a $\{chi}^2$ -test of independence by using contingency table. We also apply a proposed test to some non-linear crptosystems and show that this useful to evaluate the strength of the cryptosystems.
