Owing to their low scalability, weak support on big data, insufficient data collaborative analysis and inadequate situational awareness, the traditional methods fail to meet the needs of the security data analysis. This paper proposes visualization methods to fuse the multi-source security data and grasp the network situation. Firstly, data sources are classified at their collection positions, with the objects of security data taken from three different layers. Secondly, the Heatmap is adopted to show host status; the Treemap is used to visualize Netflow logs; and the radial Node-link diagram is employed to express IPS logs. Finally, the Labeled Treemap is invented to make a fusion at data-level and the Time-series features are extracted to fuse data at feature-level. The comparative analyses with the prize-winning works prove this method enjoying substantial advantages for network analysts to facilitate data feature fusion, better understand network security situation with a unified, convenient and accurate mode.

This study examined preschoolers' compliance and noncompliance as it related to maternal behavior, child gender and age, and social context. The subjects were 213 preschool children in Seoul. Data were collected via questionnaires reported by mothers and teachers. The results of correlation analysis and a series of repeated measures ANOVA revealed that mothers' coercive parenting was associated with lower committed compliance and ignorant noncompliance. It was also found that the 5-year-olds studies showed higher committed compliance in moral situations whereas the 6-year-olds showed higher situational compliance in conventional situations. Noncompliance was more common among the 5-year-olds than the 6-year-olds. It was also found that girls exhibited higher compliance than boys in both moral and conventional contexts. The results were discussed in terms of a developmental perspective.

purpose: The study was done to analyze the concept of moral distress in nurses. Method: The Hybrid Model was used in this study. For the theoretical phase, nursing and other literature were reviewed to analyze attributes and develop a working definition of the concept, moral distress in nurses. For the fieldwork phase, In-depth interviews were conducted with six nurses. Results: Four higher level concepts of moral distress in nurses were found; situational, cognitive, behavioral, and emotional, and 8 subscales, negative medical behavior, negative nursing behavior, excessive economic load, irrational organization administration, internal restraints, external restraints, negative behavioral responses, and negative emotional responses. Conclusion: it is necessary to develop programs of arbitration that will lessen the moral distress in nurses working in clinical practice.

Individual adoption and sustained usage of information technology(IT) are crucial prerequisites for exploiting IT as integral components of organizational work. Previous studies on technology adoption in workplace suggest that acceptance behavior is influenced by a variety of factors such as individual differences, social influences, beliefs, attitudes, and situational influences. In this paper, we introduce a research model to predict the usage behavior of intranet in workplace and also explain the causal relationships among variables. Based on the survey of 333 intranet users, this study uses structural equation model with LISREL 8.12. This study suggests several major results from surveys and analysis from them. Perceived use is influenced by intranet experience, task equivocality, organizational support, and perceived ease of use, Experience and organizational support determine perceived ease of use. Task equivocality, task interdependence, and organizational support have positive effects on subjective norm. On the other hand, present usage, which is a dependent variable in this model, is influenced by perceived use, experience, task interdependence, and organizational support.

This research was intended to provide conceptual framework of clothing conformity by determining motivation types of clothing conformity and nonconformity, and their relation-ships. The responses of 714 fulltime employeed subjects from four different cities were analyzed. Business were was used as the situational stimulus. The literature study suggested three different motivation types of clothing conformity including Normative Conformity, Informational Conformity, and Identificational Conformity, and two different types of clothing nonconformity including Anticonformity and Independence. As the results of the empirical analysis, clothing conformity types were found to be Normative Conformity and Identificational Conformity. Clothing nonconformity types were found to be Anticonformity and Independence. Identificatinal Conformity correlated positively with Anticonformity and negatively with Independence, whereas Normative Conformity correlated negatively with Anticonformity and Independence.

Data from a series of four studies on leadership behavior are analyzed and compared to identify effective patterns of leadership behavior for platoon leaders and battalion commanders in ROK Army. Multiple-method research strategy is utilized in four studies to overcome some of the limitations of previous researches. Two of four studies employ a questionnaire method, and the rest use content analysis of critical incidents. Important behaviors for leadership effectiveness in both platoon leaders and battalion commanders include Supporting and Motivating Task Commitment. However, Developing and Monitoring Operations are only important in platoon level, and Planning & Organizing and Recognizing & Rewarding only in battalion level. Most discrepancies in results among studies can be explained in terms of either method effects or situational differences in role requirements for leaders.

In rural settlement planning, its spatial development framework should be constructed on the basis of the hierachial settlement system. However, up to now, there does not exist widely - accepted model on rural settlement hierachy. In this study the basic planning principles and directions on the modelling of the settlement hireachy in rural areas have been consolidated through theoretical study and situational analysis on planning environments. And also, a new yardstick on the grading of the middle - level centers between villages and rural towns has been tried to find out. The research resulted that the existance of periodical rural market might be used as a simple and innovative yardstick on the hierachial ordering of rural settlement system. Based on the above results, an alternative 4 - step model of rural settlement hierachy was proposed ; Rural Town(county hall sitted) -Market Center(having standard periodical market) - Village Center(having no market) - Village. Finally, because the conclusion has been made by very limited case studies and several previous works, there should need continuous studies and checks in future for full reasoning of the proposed model.

This research was intended to identify variables influencing on risk perception and risk reduction behavior in clothing purchase situations. Responses from 631 female adults living in Seoul area were collected and analyzed. Towner for social occasions or working in office was used as clothing stimulus. The analysis included three product variables(price, style, type of clothing), 4 personality variables(generalized self-confidence, specific self-confidence, generalized informativeness, fashion informativeness), 2 clothing attitude variables(clothing importance, clothing interest), 4 demographic variables(age, educational level, occupation, income), and 3 situational variables(purchase planning, time pressure, effects of shopping company). Multiple regression revealed the fact that each type of clothing risk and each type of risk reduction behavior was influenced by the set of different variables. Generalized self- confidence and age and time pressure had more effects on clothing risk perception, while clothing risk reduction behavior was more influenced by clothing risk type, clothing interest, price of clothing and fashion informativeness. Implications for marketing strategies planning were also provided.
