Nowadays, UI(User Interface)'s main target area is getting larger from user's convenience oriented interface, to user's satisfaction oriented interface. In this study, we attempted 'Storytelling User Interface' for fulfillment of user's satisfaction. We analyzed UI in games, distinguished and clarified its effectiveness that conveys main contents and special features to its audience. The most important element in storytelling UI is 'Inherent Drama'. This was proved through the game analysis with Blizzard's 'Diablo', Sierra's 'Home world', Eden Games' 'Test Drive Unlimited', EA's 'Black And White', and Sony Entertainment's 'Eye Of Judgment'. And we divided storytelling elements into 3 pieces, Mood Design - that shows story's background, or traits, Natural Control - for user's feeling as a hero in the content, and Flow Directing - using animation, visual design and sound, etc. Via these elements, we can make the best use of background, icon, animation, every structures and flow in games. Finally, we embodied three pieces for putting in practice for effective improving interface.

The purpose of this paper is to find out the origin and significance of Sipgan-Sipiji that Yinyang and five elements are assigned. By looking at the hypotheses that Sipgan-Sipiji may have originated from the ancient Chinese calendar, the contents of the materials recorded in the classical literature, and the records left in the Oracle bone script, we wanted to explore the starting point of Sipgan-Sipiji in Eastern humanities and social sciences that could never be overlooked. Through the literature review of Sipgan-Sipiji, the researcher believes that this code system was completed by Hwangje and his teacher Daeyo, who led paternal clan society in the latter part of the Chinese Neolithic Age, because of supporting the use of the October calendar associated with Sipgan, and because Sipgan in the Oracle bone script seems to keep the sacredness and at the same time to be used to document the time. I believe that this consideration of Sipgan-Sipiji will be helpful for future related research in the process of underlying the research effort of Myeongri Science, such as the security of the logic of the theoretical framework for the theory system and the proof through statistical social science techniques.

In order to obtain data for developing an ideal science curriculum. four kinds of General Science textbooks based on the 6th curriculum were analyzed. Particularly inquiry activities were analyzed by Scientific Inquiry Evaluation Inventory(SIEI). The results are as follows: 1) The average number of inquiry activities in four kinds of textbooks is 115.5. And the number in each textbook is very diverse: textbook A contains 94 inquiry activities, textbook B 147. textbook C 100 and textbook D 121. 2) As for the number of inquiry activity scopes in four kinds of textbook. observation comes to 22, experiment 117, interpreting data 196, investigation 64, discussion 51, classification 4 and prediction 8. And then the conceptional inquiry activity is about 2.3 times as many as the inquiry experiment. 3) According to the analysis of each inquiry task by SIEI. textbook A has 268, textbook B 328, textbook C 207 and textbook D 304. 4) In the analysis of the structure of inquiry activity, the evaluation of the competition and cooperation scale shows more emphasis on common tasks. no pooled results(87.1 %). The discussion scale mostly consists of activities without discussion required among students(83.5%). The evaluation of openness scale shows more emphasis on activities with problems, procedures and answers presented(58.3%). In the evaluation of inquiry scope scale, the inquiry scope scale mostly has the activities to demonstrate or verify the contents of the text(66.9%). 5) As for the analysis of inquiry activities as a whole. The inquiry pyramid in four kinds of General Science textbooks shows the type I that emphasizes the inquiry activities in low level such as gathering and organizing data. The inquiry index in four kinds of textbooks is average 47.8, shows very high level (above 35).

The purpose of this study was to test the mediation effects of adolescents' ego-resilience on the relation between neglect, abuse and life satisfaction. The 6-year longitudinal data from the Korean Children & Youth Panel Survey (KCYPS) were collected from 1st grade middle school students. The data were analyzed by structural equation modeling and Sobel testing.The results of this study were as follows. First, the results revealed that the path from neglect and abuse to life satisfaction was partially mediated by family relations. The relations between trauma(neglect) and ego-resilience are negative(${\beta}=-.258$, p<.001). The relations between ego-resilience and life satisfaction are positive(${\beta}=.843$, p<.001). Second, the verification of the mediation effect of ego-resilience showed that ego-resilience was a full mediator between trauma(neglect) and life satisfaction for 1st grade middle school students(Z=-.169, t(CR)=-.012 (p<.05). Based on these results, the practical implications were discussed.

Dissemination of XML data on the internet could breach the privacy of data providers unless access to the disseminated XML data is carefully controlled. Recently, the methods using encryption have been proposed for such access control. However, in these methods, the performance of processing queries has not been addressed. A query processor cannot identify the contents of encrypted XML data unless the data are decrypted. This limitation incurs overhead of decrypting the parts of the XML data that would not contribute to the query result. In this paper, we propose the notion of query-aware decryption for efficient processing of queries against encrypted XML data. Query-aware decryption allows us to decrypt only those parts that would contribute to the query result. For this purpose, we disseminate an encrypted XML index along with the encrypted XML data. This index, when decrypted, informs us where the query results are located in the encrypted XML data, thus preventing unnecessary decryption for other parts of the data. Since the size of this index is much smaller than that of the encrypted XML data, the cost of decrypting this index is negligible compared with that for unnecessary decryption of the data itself. The experimental results show that our method improves the performance of query processing by up to 6 times compared with those of existing methods. Finally, we formally prove that dissemination of the encrypted XML index does not compromise security.

Volume visualization is an important subarea of scientific visualization, and is concerned with techniques that are effectively used in generating meaningful and visual information from abstract and complex volume datasets, defined in three- or higher-dimensional space. It has been increasingly important in various fields including meteorology, medical science, and computational fluid dynamics, and so on. On the other hand, virtual reality is a research field focusing on various techniques that aid gaining experiences in virtual worlds with visual, auditory and tactile senses. In this paper, we have developed a visualization system for CAVE, an immersive 3D virtual environment system, which generates stereoscopic images from huge human volume datasets in real-time using an improved volume visualization technique. In order to complement the 3D texture-mapping based volume rendering methods, that easily slow down as data sizes increase, our system utilizes an image-based rendering technique to guarantee real-time performance. The system has been designed to offer a variety of user interface functionality for effective visualization. In this article, we present detailed description on our real-time stereoscopic visualization system, and show how the Visible Korean Human dataset is effectively visualized on CAVE.

In this study, we analyzed the explanations and examples of Brønsted-Lowry model in Chemistry I and Chemistry II textbooks of the 2009 revised curriculum. In particular, the definition of the Brønsted-Lowry model, the examples, and the content of experiments were analyzed by the process perspective of chemical equilibrium, emergent process. The analyzed textbooks were 4 kinds of Chemistry I textbooks and 4 kinds of Chemistry II textbooks in 2009 revision curriculum. As a result, Chemical I textbooks did not adequately show the chemical equilibrium viewpoint when explaining the Brønsted-Lowry model. In the Chemistry II textbooks, the examples of Brønsted-Lowry model were not present emergent process viewpoint, and those were described as sequential viewpoint of Arrhenius model. In addition, examples of experiments to demonstrate the Brønsted-Lowry model of Chemistry II textbooks were insufficient. The experimental examples related to the definition of acid bases were at the level of classification by the color change of indicators. The experimental examples for explaining the strength of acid and base were to compare current intensity or amount of hydrogen gas generated from the reaction with metal. In addition, all textbooks presented the state of aqueous solution when describing the Brønsted-Lowry model, causing problems with differentiation from the Arrhenius model. Therefore, it is necessary to develop examples of experiments to help students understand Brønsted-Lowry model by presenting acid and base reaction in the non-aqueous solution state.

The purpose of this study was to examine the characteristics of domestic research into breast-feeding intervention education geared toward mothers and the content of the intervention based on the existing literature in an effort to provide information on how to offer the best intervention. Domestic studies reported between January 1993 and December 2014 were analyzed using four different databases. Fifteen studies were selected from 76 studies included in the databases after performing the searches. How long breast-feeding intervention remains effective should be studied to secure scientific rationales, which is one of the proper nursing interventions to boost breast feeding. As a result of analyzing the papers according to Whittmore and Knaf's integrative review method, the individual educational intervention was offered in two papers, and the individual education and group education were both provided in four. In nine papers, individual education, group education, phone counseling and education by home visits were all offered. Follow-up studies should be conducted by adopting a systematic research design to find more scientific evidence for appropriate nursing interventions to boost breast-feeding. These results will be useful for the development of educational programs for breast-feeding if more accurate information on breast-feeding education for mothers can be obtained.

This study, focusing on process of online Word-of-Mouth(oWOM) adoption in applications market which is a major issue of recent mobile industry, tried to empirically analyze how main characteristics of oWOM affect trust and process of oWOM adoption. To do this, based on understanding about applications market and precedent studies on online communication and Elaboration Likelihood Model(ELM), I developed the research model and proposed seven hypotheses. The subjects were smart phone users who ever used review in mobile applications market. The study method was questionnaire survey. As a result, trust in review was suggested as prerequisite for consumers to accept on-line review in mobile applications market. And it was empirically proved that for the customers to feel trust, these are necessary - positive assessment on argument quality, vividness of delivered explanation, and neutrality of message. The theoretical implications of this study are that based on studies on oWOM, factors affecting trust in review were explored in the environment of mobile applications market with less judgement clues for decision making compared to other on-line media and then, these factors were conceptualized. From the practical view, this study suggested implication on what attributes companies or developers can strategically utilize while investigating prerequisites of oWOM adoption.
