The purpose of this study was to investigate the differences in social anxiety and stress coping style by the college students' levels of self-efficacy. The convenience sample consisted of 400 college students in six universities. The data were collected from May to June in 2013 using the following instruments: the Self-Efficacy Scale, the Interaction Anxiousness Scale and the Ways of Coping Questionnaire. Descriptive statistics, t-test, ANOVA, and Pearson correlation coefficient were used to analyze the data using SPSS 21.0. Self-efficacy was found to have negative relation with social anxiety and positive relation with active coping style while social anxiety was negatively related to active coping style and positively to passive coping style. There were differences in social anxiety and stress coping style in accordance with the level of self-efficacy. The higher group in self-efficacy used more active coping than the lower group. The support and intervention program to increase self-efficacy would be effective in decreasing social anxiety and increasing active coping style among college students.

This is a quasi-experimental study involving one group design with pretest and posttest for evaluation of an effectiveness of an emergent care management simulation education among senior nursing students according to their learning styles. Participants were 58 senior nursing students. Learning style and educational effectiveness (critical thinking disposition, problem solving process, cooperation, satisfaction with learning, and self-confidence) were measured. Learning styles of senior nursing students were converger 46.6%, assimilator 34.5%, accommodator 15.5%, and diverger 3.4%. Critical thinking disposition, problem solving process, cooperation, and self-confidence were significantly enhanced by an emergent care management simulation education. Otherwise, educational effectiveness according to learning styles were not significantly different. Based on the results, devising stratagem to maximize an educational effectiveness will be needed trough re-evaluation of relationship between learning styles and effectiveness of a simulation education.

Since DMB on-air was started, not high-qualified audio, video services but various service models have been required. This paper is about systems for one of these services, video associated data service. A terrestrial DMB system to make contents of video associated data services and transmit them on DMB channel is proposed in this paper. This system satisfies standard of the video associated data services for terrestrial DMB; MPEG-4 BIFS (BInary Format for Scene) Core2D scene description profile and graphics profile. This system is designed to support two major features of broadcasting, real-time authoring non automatic transmission and non real-time authoring automatic transmission, and focuses on the abilities to make high-qualified contents efficiently and transmit them to video encoder reliably. This system proved its performance through conformance tests with various receivers, so can be used in future on-air.

This paper introduces an adaptive nonlinear filtering algorithm that uses the sequential regression(SER) method to update the second order Volterra filter coefficients in a recursive way. Conventionally, the SER method has been used to invert large matrices which result from direct application of Wiener filter theory to the Volterra filter. However, the algorithm proposed in this paper uses the SER approach to update the least squares solution which is derived for Gaussian input signals. In such an algorithm, the size of the matrix to be inverted is smaller than that of conventional approaches, and hence the proposed method is computationally simpler than conventional nonlinear system identification techniques. Simulation results are presented to demonstrate the performance of the proposed algorithm.

Computational thinking is an ability to resolve problems that may be applied to the various real world problems and is regarded as the core of computer science. Computational thinking may be improved through experiences of analyzing problems and of selecting, applying, and modeling strategies appropriate for problem-solving. In order to enhance computational thinking of learners, it is important to provide experiences of solving various problems. This study designed puzzle based learning in order to educate learners principles of problem solving, let them have experiences of interest and insight, and provide them with problem solving experiences. The puzzle questions used for learning were classified into six types - constraints, optimization, probability, statistics, pattern recognition, and strategies. These questions were applied to Informatics gifted elementary students and, after their education, their computational thinking and problem solving inventory significantly improved.

The purpose of this study was to examine influencing factors on plastic surgery addiction tendency. The participants, 223 undergraduate women, completed the ACSS, SATAQ, and MBSRQ. Data were collected from May, 2014 and analyzed using descriptive statistics, chi-square test, ANOVA, logistic regression analysis. Each of variables related to plastic surgery were analyzed between positive expectation group, addiction risk group, or addiction group compared to stable group. The prevalences of stable, positive expectation, addiction risk, and addiction group were 21.1%, 35.0%, 32.7%, and 11.2%, respectively. 45.7% had at least one personal plastic surgery. Personal experience of plastic surgery, high levels of ACSS (Consider), high levels of SATAQ (Internalization), and high levels of MBSRQ (Appearance Evaluation) were all associated with plastic surgery addiction tendency. The results of this study suggest that prevention of early plastic surgery, sociocultural influence and body image disturbances as well as safe guidance for plastic surgery are important in preventing the plastic surgery addiction.

The aim of this study is to reinterpret the image on a Korean tradition known as Bang-wee-shin-sang (an image of direction deity), and to revive the image into Jikimee (the guardian). In particular, this research re-analyzed the image and the symbol of Bang-wee-shin-sang and effectively designed the tradition to fit the modern living space. The theoretical study is to explore why it is necessary to redesign Bang-wee-shin-sang to accommodate modern living after examining the background and origin of typical Korean traditions such as Four Deity painting, Chinese Zodiac, and Four Kings' Painting. As a previous study, we examined the procedures of making Jikimee which was based on artists' works that utilized historical artifacts. The study indicated that Bang-wee-shin-sang is a vital resource to disseminate the unique characteristics of Korea and its tradition which played a role in linking the past and the present. Consequently, it is discussed that the utilization of modernized Jikimee in smart environment must be supported by foundation of academic system, the effort of academic and research link, and government funding policy.
