Abstract Due to the rapid development of the information communication industries, it is expected that next-generation mobile communication devices in the data communication environment will be used at the same time in the L~X band (1–12 GHz). To mutual electric wave interference prevention, research on wave absorbers in L~X band is needed. In this paper, barium ferrite was researched as L~X band wave absorber. The Barium ferrite (BaM, Ba ferrite) substituted by divalent ions (Co2+, Cu2+, Ni2+, Zn2+) and tetravalent ion (Ti4+). The substituted Ba ferrite nanoparticles were fabricated by sol-gel process. Lattice parameter, particle size, magnetic properties, and reflection loss were analyzed by X-ray diffraction (X-RD), a Vibrating Sample Magnetometer (VSM), and a Network Analyzer. Lattice parameter of Ba ferrite was changed 0.0005 to 0.0078 Å in a-b direction, and 0.0187 to 0.0445 Å in c-direction by substituted elements, and it influenced on magnetic anisotropy. In addition, Co-Ti substitution elements influenced that coercive force decrease 5,739 to 2,240 Oe. Moreover, reflection loss frequencies were shifted from 16.3 GHz to 14.4 and 17.4 GHz by substituted elements Co-Ti and Zn-Ti.

The cooperation among ASEAN countries and East Asia countries gives advantage and challenge for each member country. Each country can improve their term of trade through international trade. The aims of this study are to analyze the impact of transportation infrastructure and information communication technology on term of trade in ASEAN countries (consist of Indonesia, Thailand, Singapore, Malaysia, Philipines and Vietnam) and East Asia countries (consist of China, Japan, Hongkong and South Korea). This study used panel yearly data of term of trade, index of transportation infrastructure, cost of export/import, time to export/import, internet user, and export/import of communication devices. Time references were 2006-2011. Statics panel data model was used to determine the relationship between term of trade and these variables for ASEAN and East Asia. Dummy intercept was applied to explain the differences between ASEAN countries and East Asia countries. The results expose that both in ASEAN and East Asia Countries, transportation infrastructure and the export value of communication devices have a positive correlation on the term of trade, whereas cost of export has a negative correlation on term of trade.  To increase the term of trade, each country should be improve the quality of transportation infrastructure, increase export of communication devices,and reduce the cost to export. Keywords: term of trade, transportation infrastructure, information/communication devices, static panel data model

Abstract Speech-language pathologists, working in a multicultural, community-based environment for young children with special needs in Vancouver, Canada, collected information on 84 clients using AAC from a chart review. The speech-language pathologists collected additional usage information and attended a group interview to discuss barriers and facilitators of AAC. Thirty-one percent of the children were using AAC. Children aged between 16 and 72 months typically relied on multiple modes of communication, including sign, communication boards and binders, and low- and high-tech communication devices. All of the children used at least one type of unaided mode. Fifty-five percent used pictures or communication boards/displays, and 29% used technology with speech output. Similarities in usage of AAC were noted in home and child-care settings with increased use of unaided in homes and a slightly increased use of aided communication in child care settings. Speech-language pathologists reported that the time needed for AAC intervention as well as limited funding for high-tech devices continue to be major barriers. Additional research is needed to describe current AAC practices with young children particularly from minority linguistic and cultural backgrounds. Stakeholder input is needed to explore perceptions of children's usage of AAC in daily life with familiar and unfamiliar communication partners.

Innovations in technology have resulted in increased use of tablets, mobile devices, and applications as augmentative and alternative communication (AAC) systems for children with complex communication needs (CCN). Although research has been conducted on the specific characteristics of AAC technologies, many interfaces remain replications of prior communication devices with little consideration of the features of newer platforms. A greater concern is that these interfaces may not be based on empirical evidence or derived from key developmental language theories. As such, these interfaces may place additional demands on children with CCN instead of supporting their development of language content, form, and use. The purpose of this paper is to discuss potential interface supports for AAC systems that capitalize on current technologies and draw upon key tenets of developmental theory.

The purpose of this mixed methods study was to determine the barriers that special educator teachers encounter when using iPads within the Life Skills classroom. The research investigates the experiences, frustrations, and barriers through educators’ perceptions of iPad implementation. The influence of these issues suggests why iPad usage is not a device that special education classrooms are using in a widespread daily manner. Exploration of iPads as an educational tool and as a communication device is also discussed, along with considerations of other communications systems such as Picture Exchange Communication Systems and Alternative and Augmented Communication Devices is considered. Recommendations for further possible research are also discussed.
