The purpose of this study is to identify the composition elements and processes of the rock cycle that pre-service teachers in earth science field understand. Second-year students majoring in earth science were selected as research objects, all of whom attended teacher's university located in the southern region. The methods of arranging the composition elements of the rock cycle in a structured way and displaying the cycle direction through the arrow and describing the cycle processes in detail were applied. Pre-service teachers recognized 5 composition elements: magma, igneous rocks, sediments, sedimentary rocks, metamorphic rocks of the rock cycle and cycle processes was represented into 20 branches. The cycle type was analyzed by four criteria: linear, triangular, circular, complex, some pre-teachers did not complete the loop of the cycle or some showed incomplete understanding of the cycle structure simply displayed in one direction. The rock cycle is an important theme of the earth system education characterized by dynamism and complexity.

This exploratory study outlines the rationalization of why Ontology's taxonomy requires a strong hierarchy, accuracy, and interoperability in order to be used as a successfully re-useable information management system. Finding the relevant information in a plethora of possible resources by bridging the gap between the user's needs and the resources of the information technology system is the goal that the information management field should find a way to achieve. This study is based on discussions and interviews with a taxonomist, information architect, and information manager, whose discussions were based on the usability and interoperability of the knowledge based information systems. These professional perspectives are necessary as they are the liaison between users and the information technology group. We found that in order for information managers to ensure successful sharing of knowledge across the end users, a common sense language must be issued in order to achieve reasoning for the artificial intelligence system.

The convergence of metadata service and the PDR with digital storage device enables new services. Among which, providing dynamic commercials make it possible for the commercials stored in the PDR to be a beneficial information source instead of a dull and not-so-interesting time-consuming content. It also improves consumer concentration and makes the commercials more effective. This paper provides list of various functionality provided by dynamic personalized commercials based on metadata and PDR. The proposed information structure supporting these functionality is based on the digital item concept of MPEG-2I. This paper also provides brief description on how the proposed information structure can be used to implement the listed functionality of dynamic persona1ized commercials.

Several methods which utilize the phase of Zernike moments (ZMs) to estimate the rotation angle have shown good performance in terms of accuracy. In this paper, we provides the performance comparison results of the existing rotation angle estimation methods based on ZMs and propose an extension of Revaud et al.'s method [1] which utilizes the phase of ZMs; the proposed method uses angular radial transform coefficients instead of ZMs and yields better performance than the ZMs based methods in terms of accuracy. A set of ART can describe angular variation of image more intensively than ZMs, it enables more accurate estimation of the rotation angle than ZMs. In the experiments, the proposed method outperforms ZMs based method. Comparisons were made in terms of the root mean square error vs. the coverage on MPEG-7 shape dataset.

Web technology for next generation, led by W3C, is focusing on overcoming of limitation of Human-oriented Web. With circumstance of dramatic increasing information flow in current existing Web, human view based HTML technology is significantly loosing its value. To overcome limitation of Human-oriented Web, new alternative method is essentially required In this context, Machine-oriented Web which machine is searching for information, has been researched as a new alternative. This thesis reviewed MDL (Meaning Definition Language) which is regarded as most generally using method for implementation of Machine-Oriented Web, and presented modeling concept and implementation method in detail. To verify tile value of this presented implementation method, this thesis includes actual cases which has based on proposed implementation method. As an end, we have tried to give a technical assistance to developer of MDL Editor by suggesting MDL Editor implementation display, which has been founded on the proposed modeling method.

This study is a descriptive study to investigate the effect of depression and self-esteem on suicidal ideation in nursing college students. Data collection was conducted from May to July 2015 for 3 nursing students. Data were analyzed by descriptive statistics, t-test, ANOVA, tukey post hoc test, Pearson's correlation and multiple regression. There were significant differences in depression with grade and school life satisfaction, self-esteem in sex, grade, grade, and school life satisfaction and suicidal ideation showed differences in school life satisfaction. There were positive correlation between depression and suicidal ideation, while there were negative correlation between self-esteem and suicidal ideation, and depression. The factors affecting suicidal ideation were depression(${\beta}=.346$, p=.000) and self-esteem(${\beta}=-.290$, p=.000). The explanatory power of the variables was 33.2%. This study suggests that a systematic education on depression and self-esteem is needed to reduce the suicidal ideation of nursing college students.

The purpose of this study is to clarify the factors that affects smartphone addiction of elementary school students. The subjects were 263 students, from 4 elementary schools located in G-city. Data were collected from July, 2014 and analyzed using SPSS 19.0 program. The prevalence of addiction risk group and non-addicted group were 16.0% and 84.0%, respectively. The variables which had statistically significant differences with smart phone addiction of general characteristics are grade, living together family, economic status, school record, motivation for usage, advantage of usage and using time (p<.05). There was pure correlation between the smartphone addiction and impulsivity (r=.496, p<.001), daily stress (r=.471, p<.001). However, perceived parental attitude (r=-.375, p<.001) and self-esteem (r=-.444, p<.001) were inverse correlation with smartphone addiction. Higher using time, higher impulsivity and higher daily stress were all associated with increased of smartphone addiction level. These results suggest that more attentions should be given to early adolescents and could be effectively used as fundamental data to develop intervention programs, which can prevent the smartphone addiction.
