Due to the advantages of Internet, many teachers use Internet as an educational tool and due to the computerized works in schools, the usages of the Internet increase. However, because of the openness of the Internet, the sensitive data of an organization are exposed to outsiders and the Internet-based working has some problems such as the corruptions of instructional data or on-line assessment results. The need for protecting a school network from outsiders increases but the school networks with firewalls rarely exist. In this paper, in order to solve the security problem of a school network, we construct a hybrid firewall for school networks. In addition, we implement a graphical user interface for teachers to set up the access control rules of a hybrid firewall easily. The interface also provides the facilities such as log analysis, a real-time monitor for network traffics, and the statistic on traffics.

The purpose of this study is to empirically investigate critical success factors for effective implementation of web-based distance learning system. First of all, four critical success factors are theoretically derived from reviewing previous research. They are: (1) learner-related factor including the variables such as teaming ability, learning attitude, and attending motivation, (2) environmental factor including the variables of physical and mental support for learners, (3) instructional design factor represented by one variable, the degree of appropriateness of learning contents, and (4) the factor concerning the level of self-directed learning readiness embracing the variables such as curiosity for learning, openness towards challenge of learning and affection for learning. Subsequently, the relationships between these four critical success factors and the degree of learning satisfaction are empirically investigated. The data for empirical analysis of the research are collected from 1,020 respondents who have already passed the web-based distance learning courses which have been implemented in Information and Communication Officials Training Institute. Out of 1,020 responded questionnaires, 875 data were available for statistical analyses. The main results of this study are as follows. Firstly, the most important factor for successful implementation of the web-based distance learning system is shown to be the instructional design factor, and in the next place, the self-directed learning readiness factor, the environmental factor and the learner-related one in sequence. Secondly, additional analysis of the variables included in the instructional design factor shows that availability of practical information and knowledge is the most influencing variable, and next, interesting composition of contents, reasonable learning amount, optimal level of instruction, and understandable explanation are significantly important in the descending order. Lastly, among learning motivators, strong intention of acquiring business knowledges and skills is found to be the most important satisfier in the web-based distance learning. The theoretical contribution of this study is to derive a comprehensive model of critical success factors for implementing the web-based distance learning system. And, the practical implication of this study is to propose efficient and effective guidelines for developing and operating the web-based distance learning system in the various kinds of organizations.

Purpose: This study was done to identify the factors affecting the perception of patient-safety-culture and the level of safety-care-activity among nurses in small-medium sized general hospitals. Method: Data were collected during April and May 2011, from 241 nurses of five hospitals. A hospital survey questionnaire on patient-safety-culture and safety-care-activity was used. Collected data were analyzed using descriptive statistics, Pearson correlation, t-test, ANOVA, Scheffe test and multiple-regression. Results: There were significant differences in the level of perception of patient-safety-culture according to the nurses' age, type of hospital, position, work department, and knowing whether there was a Patient-Safety committee in their hospitals. Nurses with higher perceived level of the patient-safety-culture performed more safety-care-activities. Factors influencing on the safety-care-activities were general patient safety, having had safety-education, patient-to-nurse ratio, employment status, and the level of reporting medical errors. These factors explained 22.9% of the safety-care-activity. Conclusions: The study findings suggest that in order to improve the nurses' perceived level of patient-safety-culture and safety-care-activity, the hospitals need to establish patient-safety committees and communication systems, and openness to reporting medical errors are needed. Better work conditions to ensure appropriate work time, regulate patient-to-nurse ratio, and nursing education standards and criteria, are also required.

The purpose of this study was to evaluate the level of elementary gifted students' argumentation and examine the special features of argumentation founded in scientific inquiry. 28 students were selected in the special education center for the gifted in K National University. They were organized 8 groups of 3~4 students and engaged in scientific inquiry activity. The researcher wasn't involved in students' inquiry activity and argumentation except for the guiding and introducing their activity. In the first session, each group carried out the experiment 'Putting a heated can in the water' and then, the students discussed to probe their experimental results and build their explanation. In the second session, each group presented their experiment results and evidence from their experiment justifying their claims, and had questions from other groups. The protocol data during 8 groups' argumentations were analyzed using 'Rubric for Scientific Argumentation Assessment' (Yang et al., 2009) in three domains- the form, content and attitude. As a result, in form domain, almost groups were rated 2 points due to their argument without rebuttal on the subcategory of 'composition', but they got a good grade above 3 points in subcategory such as 'claim', 'ground', and 'conclusion'. In content domain, almost groups got points above 3 points. In attitude domain, there were some striking contrast between each groups. Six groups got good score more than 4 points on the subcategory of openness, but two groups, they alleged and got score below 3 point. While the 6 groups of all got 4 points in the aspect of participation, 3 groups got 3 points lower than because they only just asserted and not interact with other groups. Throughout the argumentation, two features were found that; as time goes by, arguments were refined; Students tended to use their prior to knowledge rather than evidence such as experimental data in making claims and conclusions.

This study explores the correlation between personality traits, customer orientation, job satisfaction, and job performance. This study examines the impacts of personality traits and customer orientation on job satisfaction and job performance. Data were collected using a questionnaire survey. A convenience sample was drawn from salespeople working for department stores in Daegu and Pohang between September $1^{st}$ to $7^{th}$ 2011. A total of 337 responses were complete and usable questionnaires. Data were tested through factor analysis, correlation analysis, and regression analysis, using SPSS 12.0. Three main points are shown through this study. First, the correlation of all five factors extracted from salespeople personality traits with customer orientation was statistically significant. Personality traits and customer orientation were partially correlated with job satisfaction or job performance. Second, the regression analysis was conducted to examine the influence of personality traits and customer orientation on job satisfaction; subsequently, only two factors extracted from customer orientation (consideration for customers and customer-centered thinking) were significant predictors of job satisfaction. Third, the result of the regression analysis between personality traits and job performance showed that the most influential predictor of job performance was conscientiousness, followed by likeability, openness and introversion. The most influential factor between customer orientation and job performance was competence in providing product information, followed by consideration for customers, customer-centered thinking, and a reliability-focused response.

The study aims to analyze the posts of depression-related Facebook groups to understand major topics discussed by group users. Specifically, the purpose of the study is to identify the topics and keywords of the posts to understand what users discuss about depression. Depression is a mental disorder that is somewhat sensitive in the online community, which is characterized by accessibility, openness and anonymity. The researchers have implemented a natural language-based data analysis framework that includes components ranging from Facebook data collection to the automated extraction of topics. Using the framework, we collected and analyzed 885 posts created in the past one year from the largest Facebook depression group. To derive more complete and accurate topics, we combined both automated and manual (e.g., stop words removal, topic size determination) methods. Results indicate that users discuss a variety of topics including depression in general, human relations, mood and feeling, depression symptoms, suicide, medical references, family and etc.

This study is to investigate the compulsive use of the social media platform, YouTube. For this purpose, this study built a research model that considered how the personality trait perspective(agreeableness, conscientiousness, neuroticism, extraversion, openness) and the use motivation perspective(utilitarian, hedonic and social use motivations) work together to explain compulsive use of YouTube. The survey method was used for this paper, and data from a total of 165 were used for the analysis. And structural equation model was used to analyze the data. The results of this empirical study is summarized as followings. First, both agreeableness and conscientiousness have a negative effect on compulsive use of YouTube. Second, utilitarian use motivation has a negative effect on compulsive use of YouTube. The results of this study are meaningful in that it not only alerts YouTube users to the risks of compulsive YouTube use, but also helps them to develop self-management strategies.
