  • The purposes of this study are to analyze sex education content in high school textbooks and to suggest new guidelines for high school sex education content from a gender equality standpoint. The study analyzes sex-related content from high school textbooks based on the 7th curriculum, including subject areas such as Technical/Home Economics, Sciences, Physical Education, Social Studies and Moral Studies. The analysis relies on the framework of Sexuality Information and Education Council of the United States that covers 4 levels and 6 categories as well as the framework of Choi (2005) that includes 36 themes in 6 different categories. The results of this study are as follows: First, high school sex-related textbooks are focused mainly on human development and human relations. Secondly, there is a lot of level 3 sex education content within the analyzed textbooks. Third, there are gender inequality issues in the coverage of such topics as pregnancy, contraception and sexual violence. Fourth, there are also gender inequality problems caused by content level. This study recommends that gender inequality issues be included in high school sex education guidelines in the future in order to provide improved and appropriate content for high school level sex education.

  • This paper explores a content-based image retrieval framework with relevance feedback based on genetic algorithm (GA). This framework adopts GA to learn the user preferences using the similarity functions defined for all available descriptors. The objective of the GA-based learning methods is to learn the user preferences using the similarity functions and to find a descriptor combination function that best represents the user perception. Experiments were performed to validate the proposed frameworks. The experiments employed the natural image databases and color and texture descriptors to represent the content of database images. The proposed frameworks were compared with the other two relevance feedback methods regarding effectiveness in image retrieval tasks. Experiment results demonstrate the superiority of the proposed method.

  • It is expected that an intelligent broadcasting service (IBS) will be able to provide broadcast programs based on user preference and program-associated information (metadata) in order to assist users in easy navigation of the program content being broadcast. In this way, users will be able to access program content anytime, anywhere, and in the manner they wish. This type of IBS will be a basis for future broadcasting services such as customized broadcasting or personal casting. In this paper, we introduce an agent-based multimedia broadcasting framework using the Foundation for Intelligent Physical Agents (FIPA) and MPEG-7 technologies within MPEG-21. We use a FIPA implementation called FIPA open source as a platform for exchanging user preferences and program information as FIPA messages between a server and its clients. The user preference is modeled as the User Preference description scheme in MPEG-7 multimedia description schemes. We discuss a framework structure and implementation for the IBS.

  • Recently, with the advance of the wireless Internet access via mobile devices, a myriad of game development companies have forayed into the mobile game market, leading to intense competition. To survive in this fierce competition, mobile game developers often try to get a grasp of the rapidly changing needs of their customers by operating their own official communities where game users freely leave their requests, suggestions, and ideas relevant to focal games. Based on the heuristic-systematic model (HSM) and the data quality (DQ) framework, this study derives key content, non-content, and hybrid cues that can be utilized when game developers accept suggested postings in these online communities. The results of hierarchical multiple regression analysis show that relevancy, timeliness, amount of writing, and the number of comments are positively associated with mobile game developers' knowledge adoption. In addition, title attractiveness mitigates the relationship between amount of writing/the number of comments and knowledge adoption.

  • Ferrisilicates with MFI type structure were hydrothermally synthesized. The structural environments of iron in the ferrisilicates were characterized by XRD, SEM, IR, EPR, and ammonia-TPD. It has been shown that pH of the final gel mixture during the synthesis affects the crystal size, morphology, chemical composition and catalyticactivity. The results of the lattice parameters, IR, and EPR indicate the existence of a framework iron and the content of framework iron depends on pH of the synthesis gel. Finally, the catalytic activity of these zeolites was examined for the cyclohexane oxidation to cyclohexanol and cyclohexanone in the liquid phase. The conversion of this reaction was increased with increasing iron content of the framework lattice positions.

  • The purposes of this study are 1) to identify systems thinking level and definition, 2) to develop a framework for the assessment of systems thinking level, and 3) to develop a rubric for scoring open-ended written responded test. In order to achieve these purposes, a total of 60 articles were analyzed by using the literature analysis framework. The systems thinking level and definition are identified through the results of systems thinking literature analysis. Based on the systems thinking level and definitions, the research derived a framework that includes the core ideas and evaluation content of each level. In addition, rubric for the scoring of open-ended response test items was revised and supplemented. It is concluded that a content validity test on the tools (systems thinking level and definition, framework for item development, rubric) has been developed in the study. The content validity was verified by 7-science education experts. According to the result of CVI, it was found to be more than .95 in all three tools. Based on the results of this study, the research will develop items that can measure students' level of systems thinking. The construct validity and criterion validity of the developed items should be verified systematically. The research could carry out a validation study for the systems thinking measurement related to the core competence emphasized in the 2015 revised curriculum.

  • In order to guarantee the compatibility of e-Book viewers based on EPUB 3, IDPF launched Readium SDK v1.0 in January, 2015, which was followed by research on the implementation of Readium LCP specifications for user-friendly DRM functions. The complexity of the Readium SDK, however, makes difficulties in interlocking Readium SDK with LCP modules. Moreover, from the perspective of the Readium SDK, which tries to maintain the architecture, independently of any specific DRM technologies, the strong interlock with LCP, as a one DRM, is not desirable. This study represents a Content Protection Framework Model for compatibility of Readium-SDK-based e-Book DRM in order to hide the complexity of Readium SDK and implement an easy interlock between plural DRM and Readium SDK.

  • While the Internet has been used to galvanise people for the collective good, many have voiced concerns over the noise and vitriol present online and polarisation. In Singapore where the government regulates traditional mainstream media such as print and broadcast, the online space has been described as a "Wild Wild West" rife with rumours, untruths and misinformation. Such developments do not only exert a potential negative effect on the deliberative nature of public discourse but also skew bias towards the online space, affecting the ability of online users to communicate with authority and power. This study seeks to examine the rationality of the cyberspace through using a new "rationality" framework to analyse political discourse online. Comprising objectivity, emotionality and partisanship, the rationality framework was applied to a content analysis of 197 blogs with political content in 2014. The analysis indicated that the online political space was not the Wild Wild West that it was touted to be with significant levels of objectivity and non-partisanship. There was a stark absence of emotional discourse, and relationships were observed between bloggers' anonymity and rationality. Cognisant of academia's and policymakers' interest on the quality and effects of online discourse, the proposed analytical framework and the study findings hold implications for both developed and developing countries.

  • Information-centric networks operate under the assumption that all network components have built-in caching capabilities. Integrating the caching strategies of information centric networking (ICN) with wireless virtualization improves the gain of virtual infrastructure content caching. In this paper, we propose a framework for software-defined information centric virtualized wireless device-to-device (D2D) networks. Enabling D2D communications in virtualized ICN increases the spectral efficiency due to reuse and proximity gains while the software-defined network (SDN) as a platform also simplifies the computational overhead. In this framework, we propose a joint virtual resource and cache allocation solution for latency-sensitive applications in the next-generation cellular networks. As the formulated problem is NP-hard, we design low-complexity heuristic algorithms which are intuitive and efficient. In our proposed framework, different services can share a pool of infrastructure items. We evaluate our proposed framework and algorithm through extensive simulations. The results demonstrate significant improvements in terms of visiting latency, end user QoE, InP resource utilization and MVNO utility gain.

  • The framework for mathematics assessments traditionally has been organized around two dimensions, a content dimension specifying the subject matter to be assessed within mathematics, and a cognitive dimension specifying the domains or thinking processes to be assessed. The cognitive dimensions describe the sets of behaviors expected of students as they engage with the mathematics content. The purpose of this paper is an attempt to make diversify and concrete the sets of behaviors by reviewing the current strands suggested by CAST(College Scholastic Ability Test), assessment framework developed by KEDI, and NAEA(National Assessment of Educational Achievement), and as famous foreign tests PISA, TIMSS, NAEP and NCTM.
