In this paper, we study the distributed cooperative caching for Internet content providers in a small cell of heterogeneous network (HetNet). A general framework based on bankruptcy game model is put forth for finding the optimal caching policy. In this framework, the small cell and different content providers are modeled as bankrupt company and players, respectively. By introducing strategic decisions into the bankruptcy game, we propose a caching value assessment algorithm based on analytic hierarchy process in the framework of bankruptcy game theory to optimize the caching strategy and increase cache hit ratio. Our analysis shows that resource utilization can be improved through cooperative sharing while considering content providers' satisfaction. When the cache value is measured by multiple factors, not just popularity, the cache hit rate for user access is also increased. Simulation results show that our approach can improve the cache hit rate while ensuring the fairness of the distribution.

The purpose of this study was to investigate the change of consumers' values as appeared in advertisements. Advertisements in men's magazine from 1976 to 1996 were classified by VALSI program. The results were as follows. 1. There was a significant trend that advertisements with outer-directed value decreased while the ones with inner-directed value increased. 2. In case of outer-directed group appeared in advertisements, There was a tendency that the hierarchy of needs shifted from emulators to achievers. However, the shift in hierarchy of needs in inner-directed group was not significant. 3. Even though the advertisements with material value were predominant, there was a tendency that the advertisement with material value decreased while the ones with human value increased.

Course evaluation serves as helpful information to improve the quality of college education and improve lectures. This study derived the factors through preceding research and FGI to explore the factors that constitute course evaluation and identified the relative importance and priority of the factors through the Analytic Hierarchy Process (AHP). For this, it derived five factors and 15 evaluation items as follows. To secure expertise and fairness in the factor development of course evaluation, the researcher conducted a questionnaire surveying students and teachers and collected a total of 20 valid data. The weight of each evaluation item was calculated based on the data that had been verified for consistency. The analysis concluded that students rated class content, class method, class operation, class evaluation, and class plan as the critical factors in the order of importance, while teachers evaluated class content, class operation, class method, class evaluation, and class plan as important, in that order. Based on the results of this study, I hope that various analyses and studies will be conducted to improve the efficiency and reliability of course evaluation for the quality management of college education.

A big success of the 3D film 'Avatar' in 2009 opened a full-fledged 3D movie era. A new industrial possibility of 3D contents was predicted in Korea and then the support for 3D contents production took placed via various media platforms. Korean government also announced the new development policies with a focus on 3D content. However, the 3D content industry has not been activated. Therefore, in this study by applying AHP(Analytic Hierarchy Process) method we tried to grasp the reason of the deactivation of 3D content industry through analyzing the relative importance rate of three research factors(content aspects, technical aspects, and policy aspects) that were mainly considered to activate the industry. The results of this study showed that the relative importance rate of content aspects was higher than that of technical aspects and policy aspects. It means the lack of 3D contents is one of main reason causing the delay of 3D industrial activation. And it also showed that the relief of human factors such as visual fatigue evaluated as a sub-factors of technical aspects are challenges to be solved soon..

In this study, we analyzed the learning elements and achievement standards, and explored the appropriateness and hierarchy of content were analyzed related to the nine types of traditional astronomical instruments presented in the traditional science unit of the History of Science course to improve the problematic situation in which students show low selection rates for the History of Science, one of the elective courses in high school science. Based on the results of this analysis, we suggested ways to utilize each astronomical instrument for teaching and learning in science curriculum with different grade bands. Using the results of this study as a starting point, if a follow-up study that develops specific achievement standards or inquiry activities related to traditional astronomical instruments can be conducted, students' awareness of Korean traditional science culture can be improved, and furthermore it is expected to increase the student's selection rate for the History of Science course.

Concept mapping was used to investigate kindergarten teachers' knowledge about early childhood literature instructional content. Participants were 87 teachers recruited by the Provincial Authority for Supervision of Education in Jeonam Province. Data were analyzed by Yun's (1998) method based on Novack & Gowin (1984), Morine-Dershimer (1993), and Markham et al. (1994). Findings were that (1) the majority of the participants perceived superordinate concepts of early childhood instructional content in literature to be typesof literature, reading, writing, speaking, expression, and listening. Subordinate concepts were stated by 456 different words. (2) Types of literature and writing were highest in frequency of superordinate concepts and were also high among subordinate concepts and hierarchy. (3) Teachers' concepts varied by teaching careers in writing and reading.

Purpose: The purpose of this study was to develop an instrument to evaluate the needs satisfaction of nurses and examine its validity and reliability. Methods: The initial items for the instrument were developed through a literature review and interviews, using the conceptual framework of Maslow's hierarchy of needs theory. The initial items were evaluated for content validity by 14 experts. Four hundred and eighty-six clinical nurses participated in this study through offline and online surveys to test the reliability and validity of the instrument. The first evaluation (n = 256) was used for item analysis and exploratory factor analysis, and the second evaluation (n = 230) was used to conduct a confirmatory factor analysis and to assess the criterion-related validity and internal consistency of the instrument. Test-retest reliability was analyzed using data from 30 nurses. Results: The final instrument consisted of 30 items with two sub-factors for five needs that were identified through the confirmatory factor analysis. The criterion-related validity was established using the five need satisfaction measures (r = .56). Cronbach's α for total items was .90, and test-retest reliability was .89. Conclusion: The findings from this study indicate that this instrument has sufficient validity and reliability. This instrument can be used for the development of nursing interventions to improve the needs satisfaction of clinical nurses.
