Blogs are readily available sources of opinions and sentiments which allows bloggers to exert a certain level of influence over the blog readers. Previous studies had attempted to analyze blog features to detect influence within the blogosphere, but had not studied in details influence at the blogger-level. Other studies studied bloggers' personalities with regards to their propensity to blog, but did not relate the personalities of bloggers to influence. Bloggers may differ in their way or manner of exerting influence. For example, bloggers could be active participants or just passive shares, or whether they express ideas in a rational or subjective manner, or they are received positively or negatively by the readers. In this paper, we further analyze the engagement style (frequency, scope, originality, and consistency of the blog postings), persuasion style (appeals to reasons or emotions), and persona (degree of compliance) of individual bloggers. Methods used include similarity analysis to detect the sharing-creating aspect of engagement style, subjectivity analysis to measure persuasion style, and sentiment analysis to identify persona style. While previous studies analyzed influence at blog site level, our model is shown to provide a fine-grained influence analysis that could further differentiate the bloggers' influence style in a blog site.

Purpose: This study was designed to explore the influencing factors on communication skill of nursing students and to investigate the relationship between learning style, critical thinking disposition and communication skill, Methods: The study sample was composed of 559 nursing students. Data was collected from 1st to 30th, May 2012 used a questionnaire which included Kolb's learning style inventory, critical thinking disposition inventory, communication skill inventory. The SPSS 18.0 Window program was used for descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and stepwise multiple regression. Results: Learning styles of subjects were diverging 39.5%, accommodating 32.6%, assimilating 22.7%, and converging 5.2%. The total mean score of critical thinking disposition and communication skill was 3.58 and 3.39 respectively. The score of Critical thinking disposition(t=3.06, p=.002) and Communication skill(t=3.25, p=.002) significantly differed between clinical practice satisfaction. Communication skill was the most significant predictor and accounted for 41.3% of the variance in critical thinking disposition in nursing students. Conclusion: It is important for students to use all four learning styles rather than to rely on one style. There should be more emphasis placed on the development of positive critical thinking disposition and communication skill of nursing students.

This study examined the effect of group counseling on the self-esteem, self-efficacy, and congruent communication style of female victims of family violence. A twice-weekly group counseling consisting of 10 sessions was provided to 5 women residing in shelters in Seoul, South Korea from October $19^{th}$ to November $20^{th}$ 2009. This study employed the self-esteem scale developed by Rosenberg(1965) and translated into Korean by Jeon Byoung Jae(1974), a self-efficacy measurement tool(Kim A Young,1997) and a congruency scale(Go Moon Jeong, 2008). The Wilcoxon non-parametric verification was used to identify the differences between before and after the group counseling sessions. The results revealed meaningful improvements in self-esteem, self-efficacy and congruent communication styles.

This study is on theoretical foundation for orthodoxy korean style Environmental Education based on oriental ecological thought. The main theme is that various kinds of all the ideas related with ecological thought based on oriental thoughts for EE should be focused into Moderation, the core-concept of oriental confuscian thoughts. The Moderation has not meant just a personal enlightenment, as it has known to general people, it can be developed into social status core-consciousness for regulating the natural resource. So we should focus on this conceptual developing mechanism personal enlightenment into social status for our orthodoxy konean style EE. It can be infered from Taoism, Confuscionism Buddism, especially, Anxiety Consciousness (WOOHWAN) for grand-scale anxiety to public society and universal cosmos. And also I drawed Harbermas-philosophy to provide good means for fortifying this research. His communication theory and restoration of real life for public people communication can be connected to oriental thoughts in the aspect of reciprocative response among the community people. So our orthodoxy korean style EE can be erected on the community-based regionality and their public communication through reciprocative response process. We should try to make this surrounding conditions nature-familiar oriental philosophy has provided from ancient times in the aspect all the traditional thought has been eco-deterministic.

Purpose: The purpose of this study was to identify the predictors of job stress in hospital nurses. The predictors of job stress were the subject's general characteristics, communication style, critical thinking disposition and job satisfaction. Methods: 294 nurses who had worked in a hospital participated in this study. The data were analysed with descriptive analysis methods including a t-test, ANOVA, Scheffe test, Pearson correlation coefficient and multiple regression analysis. Results: The job stress score for nurses was 111.6. There was a statistically significant difference between job stress and marriage status (p<.001), education (p<.001), clinical career (p<.001), position (p<.001), communication style (p<.001), critical thinking disposition (p<.001), and job satisfaction (p<.001). Critical thinking disposition, job satisfaction and clinical career together accounted for 36.88% of the total variation in job stress. Conclusion: Based on the findings of this study, the development of a nursing intervention program that can lead to an improvement in critical thinking disposition is suggested.

Clipart is artificial visual contents that are created using various tools such as Illustrator to highlight some information. Here, the style of the clipart plays a critical role in determining how it looks. However, previous studies on clipart are focused only on the object recognition [16], segmentation, and retrieval of clipart images using hand-craft image features. Recently, some clipart classification researches based on the style similarity using CNN have been proposed, however, they have used different CNN-models and experimented with different benchmark dataset so that it is very hard to compare their performances. This paper presents an experimental analysis of the clipart classification based on the style similarity with two well-known CNN-models (Inception Resnet V2 [13] and VGG-16 [14] and transfers learning with the same benchmark dataset (Microsoft Style Dataset 3.6K). From this experiment, we find out that the accuracy of Inception Resnet V2 is better than VGG for clipart style classification because of its deep nature and convolution map with various sizes in parallel. We also find out that the end-to-end training can improve the accuracy more than 20% in both CNN models.

The pixel art style evolved from the shortcomings of computer image display technology has gradually transformed from a technical limitation into a widely recognized form of artistic expression since development in the early 20th century. This study analyzes the application and characteristics of the expandability of pixel art style design content in sub industries such as physical goods, environmental design, website design, digital art and illustration in the design field. It aims to explore the visual expression and sustainable development form of pixel art style under the development of new media technology that contradicts traditional technological concepts. The research results show that although the pixel art style generally pursues external visual features such as pixelated visual effects, sawtooth and matrix arrangements, its expansion in the art field shows a unique diversity of visual expressions. It has become an important means to convey nostalgic emotions and cultural values. Through this research, we hope to inspire more academic researchers and technology practitioners to explore the development potential of the pixel art style in emerging fields and promote its innovative application in design practice.
