This study explored the educational effects of the digital citizenship teaching and learning model on middle school science classes. For this purpose, two classes of the third grade of middle school in Gyeonggi-do were selected, and the experimental group(28 students) was taught science classes using digital citizenship learning model, and the control group(28 students) was taught in regular lectures. The measurements used to verify the effects of science classes using the digital citizenship learning model were digital citizenship and empathy tools. The data collected for the effect verification were analyzed by independent sample t-test and ANCOVA. As a result, the experimental group applying the digital citizenship learning model showed higher scores of digital citizenship and empathy than the control group. Therefore, it can be seen that the middle school science class applying the digital citizenship learning model was effective in cultivating the digital citizenship and empathy of middle school students. In future studies, it is necessary to examine the effects of digital citizenship learning model at different school levels and other subjects.

Objective : This study was designed to find the characteristics of MMPI that could influence the outcome of cognitive behavioral therapy(CBT) for panic disorder. Methods : 34 patients who met DSM-IV criteria for panic disorder with or without agoraphobia had completed 11 weekly sessions of cognitive behavioral therapy. All the patients were assessed with MMPI before the initiation of treatment. Five self-report measures including Beck Depression Inventory(BDI), Spielberger State-Trait Anxiety Inventory(STAI), Agoraphobic Cognition Questionnarie(ACQ), Body Sensation Questionnaire(BSQ), and Daily Anxiety Selfrating (0 - 8 scales) were also assessed as a pre- and post-treatment assessment. After the completion of treatment, patients were classified by the High End-State(HES) functioning group and the Low End-State(LES) functioning group for the data analysis. Results : 1) The LES group showed significantly higher scores in Hypochondriasis Scale(HS), Depression Scale(D), Hysterical Scale(Hy), Obsessive Scale(Pt), Schizophrenia Scale(Sc) and Validity Scale(F) of MMPI than the HES group. However, these differences gave impressions that the LES group had more severe symptoms rather than that they could be the factors influencing the outcome of CBT. 2) Though, the severity of symptoms of the LES group in the 5 measures of pre-assessment was basically higher than that of the HES group. The fact that both group showed the similar improvement between pre- and post-assessment supported the above interpretation. Conclusion : In regarding the above results, MMPI was not a proper tool that could provide the factors influencing the outcome of CBT. In the future study, the authors need to use a different tool that can find the personality characteristics more directly.

The purpose of this study is to provide basic data for the development of the anger provoking situation scale using the mixed research method. For this purpose, three research methods were used: content analysis of domestic and international anger-inducing situation scale, NAS-PI factor and reliability analysis of youth anger-provoking scale, and FGI with youth expert. In the results of NAS-PI, there were four categories of 'unrespectful treatment', 'unfairness', 'annoying traits of others', and 'irritation' except 'frustration' among five categories. The results of the FGI consisted of seven categories: 'rejection', 'physical and verbal violence', 'ignorance', 'frustration', 'control and restraint', 'rumination', and 'interpersonal relationship'. As a result of integrating these contents, it is finally possible to reconstruction in to seven categories such as 'unfairness', 'injustice', 'ignorance', 'control and restraint', 'ignorance', 'frustration' 'interpersonal relationship'. The meaning of this study is to provide the basic data for the development of the anger provoking situation scale for domestic adolescents by integrating the contents analysis and quantitative and qualitative researches of domestic and international anger provoking situation scale. The results of this study are as follows. First, it is necessary to study the anger provoking situations reflecting sociocultural context, and to develop the reliability and validity of the anger provoking situation scale.

VaR, a tail-related risk measure is now widely used as a tool for a measurement and a management of financial risks. For more accurate measurement of VaR, recently we are particularly concerned about the approach based on extreme value theory rather than the traditional method based on the assumption of normal distribution. However, many studies about the approaches using extreme value theory was done only for the univariate case. In this paper, we discuss portfolio risk measurements with modelling multivariate extreme value distributions by combining copulas and extreme value theory. We also discuss the estimation of ES together with VaR as portfolio risk measures. Finally, we investigate the relative superiority of EVT-copula approach than variance-covariance method through the back-testing of an empirical data.

Library anxiety has been recognized as one of the representative fields that concerns user's affectivity in library and information study. Considerable library users have been discovered to experience library anxiety according to researches. Although digital libraries are becoming more popular changing drastically from traditional libraries, few studies have addressed the measurement of digital library anxiety(DLA). The purpose of this study is to develop and validate a multidimensional digital library anxiety scale(DLAS) based on previous research in library anxiety and digital libraries. It will become possible to define the construct of DLAS, provide its underlying dimensionalities, and find out how much they explain the construct. Through the exploratory factor analysis, DLAS has been developed with 39 items representing seven distinct factors which were interpreted as affect, resources, know-how, security, language, technology, and task explaining 51.165% of DLA. Also, DLAS' characteristics about demographic variables and use pattern were found through the T-test and ANOVA analysis for each factor.

This study investigates the relationship between syntactic complexity indices and scores on language use in Jacobs et al.(1981)' analytic rating scale. Syntactic complexity indices obtained from TAASSC program and 440 essays written by EFL students from the ICNALE corpus were analyzed. Specifically, this study explores the relationship between scores on language use and Lu(2011)'s traditional syntactic complexity indices, phrasal complexity indices, and clausal complexity indices, respectively. Results of the stepwise regression analysis showed that phrasal complexity indices turned out to be the best predictor of scores on language use, although the variance in scores on language use was relatively small, compared with the previous study. Implications of the findings of the current study for writing instruction (i.e., syntactic structures at the phrase level) were also discussed.
