In Information age, information problems are continuously differentiated either in individual or in social domain. The danger of reality lost is also day by day increased by digital media and the changes happen at too fast pace. Form the dialect point of view, the education of information literacy is a very important cultural media to arbitrate the conflict between the reasonable solution of the individual information problem and the social information problem. This study is an attempt to discuss the macroscopic initiative of educational system and Information ethics on the basis of the dialectic interpretation of the cultural discourse of the information literacy.

The differentiated services (DiffServ) is proposed to provide packet level service differentiations in a scalable manner. To provide an end-to-end service differentiation to users having a connection over multiple domains, as well as a flow marker, an intermediate marker is necessary at the edge routers, and it should not be operated at a flow level due to a scalability problem. Due to this operation requirement, the intermediate marker has a fairness problem among the transmission control protocol (TCP) flows since TCP flows have intrinsically unfair throughputs due to the TCP's congestion control algorithm. Moreover, it is very difficult to resolve this problem without individual flow state information such as round trip time (RTT) and sending rate of each flow. In this paper, to resolve this TCP fairness problem of an intermediate marker, we propose a fair scalable marker (FSM) as an intermediate marker which works with a source flow three color marker (sf-TCM) operating as a host source marker. The proposed fair scalable marker improves the fairness among the TCP flows with different RTTs without per-flow management. Through the simulations, we show that the FSM can improve TCP fairness as well as link utilization in multiple domain DiffServ networks.

As several users use a system simultaneously, a job management system is used to prevent exclusive uses in the system by a certain user and share entire resources for all users. The job management system is a type of scheduler that distributes limited resources for each job inquire efficiently. The system can be classified as different types and is to be properly selected according to the characteristics of systems and jobs. An NEC system is a job management system and usually applies NQS. The job management system has several queues, which are able to process jobs through distributed resources in which the efficiency of such job processing can be varied according to the composition of these queues. This study designs and configures differentiated queues according to service levels in order to improve the efficiency of the entire system as NQS is designed and that performs job processing. Also, this study analyze the performance of the job processing.

The aim of this study is to promote an appropriate consumption culture given the features of the segmented female college student group and to utilize these features as basic data at the level of consumer education. The lifestyle of female college students will be identified, along with the current use and customer satisfaction of low price cosmetics that are aimed at this group. The conclusion will be proposed on the basis of the results of this study: Firstly, low price cosmetics producers need to develop products that satisfy the needs of customers and to establish marketing strategies such as sales promotions according to the current trend. Secondly, in order to establish rational purchasing, it is necessary to promote an appropriate consumption culture by offering consumer education to college students. Thirdly, most consumers equate brands with quality. Therefore, companies need to continually produce quality products that may be differentiated from other low price cosmetics, not only in terms of price but also in terms of product quality, in order to enhance the reliability of their brand. Furthermore, it is necessary for consumers to be able to purchase products by considering product quality through searching for diverse information and not merely by depending on any particular brand.

To realize various opportunities to choose careers for adolescent sports players, first, it is necessary to help them choose a job suitable for each student's aptitude. In reality, adolescent sports players absolutely have insufficient time for choosing various careers unlike general adolescents and realizing them. Thus, differentiated and specialized convergence learning materials are needed by each job cluster suitable for adolescent sports players' aptitude. The learning materials, specialized for these individual job clusters are a method to show a great effect on education with investing the minimum time, so they have a high value for utilization as necessary learning information for the realization of various opportunities to choose various careers for adolescent sports players.

Purpose: This study was to identify the emotional intelligence, defense mechanism and interpersonal caring behavior by enneagram personality types in nursing students. Methods: A descriptive survey design was used and data were collected using questionnaires from a sample of 263 nursing students. The data were analyzed using by t-test, ANOVA, Pearson's correlation coefficient analysis with SPSS 20.0. Results: In the enneagram personality types, the nursing students was highly measured the type 9(Peacemaker). Emotional intelligence was significantly associated with financial status of parents, motivation of admission and satisfaction of nursing by enneagram characters. Hoping and sharing of interpersonal caring behaviors were significantly differentiated with the power type of enneagram personality. And active listening, comforting, participating of interpersonal caring behaviors were the most popular among the 9 types of personality. There was a positive correlation between emotional intelligence and interpersonal caring behavior. Conclusion: This study suggest that nursing students should be educated the interpersonal caring behavior program considering emotional intelligence and enneagram personality types.

This study investigates 628 high school students' math dislike tendencies by their math achievement levels. The findings show that, firstly, as the sample students' math achievement level decreases, the number of dislike factors increase. Secondly, students' math dislike factors are differentiated by their math achievement levels. Math high achievers show high math disliking tendency by teacher factor. Middle achievers show high math disliking tendency by complex application and relation factors. Low achievers show high math disliking tendency by comprehension factor. Finally the math disliking factors affecting the level of math achievement are influenced by schools and grades that students' attend. While math disliking factors such as comprehension factor, teacher factor, affection factor are generally present among sample schools, exceptionally JS high school students(high achieving students) are only affected by mentality factor. In addition, mentality factor affects the second grade students only. The implications of the study argue that students' math disliking tendencies could be systematically reduced by paying attention to such dependent variables students' achievement levels, grade, school characteristics, and independent variables including teacher, application, mentality, comprehension, and affection.

This paper illustrates a calculus module which generates step-by-step solutions using J/Link that connects Java and Mathematica. Such a module provides intermediate and low level students with a practical environment where they can easily follow the solution paths on their own paces. The extra feature of this module depicts graphical images for a given function and its differentiated result to enhance the visual understandings of calculus concepts. Mathematica as a mathematical expert system that provides systematic mathematical knowledge to students with step-by-step solutions will be possibly extended to the tutorial or CMI development. The proposed module is implemented in a Java servlet that links to Mathematica FrontEnd. This approach results in adopting font systems to express two dimensional mathematical expressions in web documents as an alternative typesetting tool.

Objectives: This study aims to compare the contents of physical activity questions of Korean National Health and Nutrition Examination Survey(KNHANES), and to propose suggestions for improvement. Methods: Questions measuring physical activity prevalence of adults in the KNHANES from KNHANES I(1998) to the first year of KNHANES V(2010) were compared. Results: The questions used in each survey showed some problems in consistency and appropriateness. Major issues identified are as follows. First, the questions in each survey were not consistent, and would be inappropriate to make time series comparisons. Second, the purpose of physical activity was not clear. Third, the examples of physical activities suggested in the questions were not appropriate. Fourth, the intensity of physical activity were not adequately described. Fifth, by excluding walking from the moderate-intensity physical activity category, the prevalence of moderate-intensity physical activity could be underestimated. Sixth, it is difficult to measure the total amount of physical activity performed in one day because answers from the other domains cannot be clearly differentiated. Conclusions: The physical activity questions in the KNHANES questionnaire should be improved so that they are consistent with the purpose of survey, the respondents can easily understand the contents of the questions, and the questions can measure all physical activity performed in the different domains.
