    Array signal processing with multiple microphones or loudspeakers is important for various applications because it can use spatial information. This article explains the fundamentals of the spatial Fourier transforms for the linear array, circular array, and spherical array from the viewpoint of the wave equation. Array processing methods in the wavenumber domain for wave field synthesis and directivity control are also described.

    In this article, we introduce the foundations of the generative model approach in statistical machine learning theory based on Markov random fields. The purpose of the generative model approach is to create a probabilistic model that mimics the source from which the observed data were generated. After explaining Markov random fields and the generative model approach, we introduce the restricted Boltzmann machine, which is a basic model of a deep generative model.

    The appearance and present situation regarding the spread of the theory of multiple intelligences are explained, and its applications are also reviewed. In particular, for the applications to university education, the applications to portfolio assessment and active learning are discussed. In terms of the questionnaire analysis of extracurricular activity in the form of externships, it is shown that the analysis based on the theory of multiple intelligences is valid, and the 'BA' model for educational activities is proposed. Finally, all students are shown to approach the flow state of Csikszentmihályi in a quantitative manner.

    MPEG Media Transport (MMT) is a next-generation media transport standard developed as a part of ISO/IEC 23008. The MMT standard specifies technologies for the delivery of coded media data for multimedia services over concatenated heterogeneous packet-based networks including bidirectional IP networks and unidirectional digital broadcasting networks. It supports hybrid delivery and multipath delivery with intermedia synchronization. MMT also supports Application Layer Forward Error Correction (AL-FEC) codes for reliable delivery in IP network environments. In this article, we introduce an overview of the MMT standard and its following applications to broadcast and broadband areas: ① a next-generation 4K/8K broadcasting service, ② ultrarealistic communication, and ③ a low-delay multicast video streaming service.
