Full-duplex communications have emerged as a key technology for next-generation wireless local area networks (WLANs). Although the key enabling technology for full-duplex communications is the self-interference cancellation (SIC) technique in the physical layer, the employment of full-duplex communications has huge potentials to substantially increase the throughput at the medium access control (MAC) layer. At the same time, full-duplex communications pose non-trivial challenges to the MAC protocol design. In this article, we first identify salient problems in supporting full-duplex communications in WLAN MAC protocols. After that, we survey the state-of-the art to address those problems and analyze their pros and cons. Finally, we present open research challenges to improve the effectiveness of full-duplex communications in WLANs.

In modern society, people will obtain the necessary goods and find meaning of himself and his community through jobs. The meaning of job for people with disabilities is identical with people's with non-disabilities and people with disabilities will live as a member of society through jobs. Because people with hearing impairment have a problem about job such as the short longevity and high turnover, vocational aptitude test which evaluates psychological characteristics, aptitudes and interests is necessary for them. In this paper, we design and evaluate the picture vocational interest inventory supporting the Internet as a vocational aptitude test for people with hearing impairment. We use the picture vocational interest inventory of Korean Employment Development Institute as a implementation target. The previous tests for people with hearing impairment have a problem which an examinee, an examiner and a sign language interpreter are involved in the test at the same space and time. Therefore, our picture vocational interest inventory has no limitation of time and space because it processes on the Internet.

The purpose of this study is to analyze the form and content of the Ordinance on Job Support for the Elderly, and to verify whether the Ordinance has formal validity and effectiveness. For this purpose, the 13 local ordinances of the municipal governments in Seoul were selected for analysis and the contents and composition of each ordinance were analyzed. As a result of the analysis, no major difference was found in the main form of the regulations such as the purpose of enactment of ordinances and contents of business. However, the scope of the policy application and the provision related to the delivery system were confirmed to be different by each regulation. In particular, residents' rights to services did not exist in all ordinances, and the obligation of local governors to provide jobs for the elderly was lacking in specificity and needed improvement. In terms of effectiveness, there are no provisions related to the delivery system or the mandatory nature of the regulations. Based on this analysis, this study proposed the directions of improvement and supplement of the ordinances.
