This paper studies the activities characteristics of the elderly aged 60-75 years old who can take care of themselves in the community public space, and puts forward the design principles of the community public space in the aging society. Using the methodology of experience design, through naturalistic observation, questionnaires, interviews and shadowing, the spatial and temporal characteristics of daily activities of the elderly are analyzed. In the community public space, the behavior of the elderly is essentially a social activity to get more attention and communication. This determines the needs, time, frequency and duration of activities of the elderly in community public space. In the community public space, the behavior of the elderly has the characteristics of long-term and regularity, and its behavior changes slightly with the space, the objective factors that affect the elderly are gender, age and climate. The subjective factors are lifestyle, family members and income level.

The paradigm of agriculture is also changing to address the problem of food shortages due to the increase of the world population, climate conditions that are increasingly subtropical, and labor shortages in rural areas due to aging population. With the development of Information Communication Technology (ICT), our daily lives are changing rapidly and heralds a major change in agricultural management. In a hyper-connected society, the introduction of high-tech into traditional Agriculture of the past is absolutely necessary. In the development process of Agriculture, the first generation produced by hand, the second generation applied mechanization, and the third generation introduced automation. The fourth generation is the current ICT operation and the fifth generation is artificial intelligence. This paper investigated Smart Farm that increases productivity through convergence of Agriculture and ICT, such as smart greenhouse, smart orchard and smart Livestock. With the development of sustainable food production methods in full swing to meet growing food demand, Smart Farming is emerging as the solution. In overseas cases, the Netherlands Smart Farm, the world's second-largest exporter of agricultural products, was surveyed. Agricultural automation using Smart Farms allows producers to harvest agricultural products in an accurate and predictable manner. It is time for the development of technology in Agriculture, which benchmarked cases of excellence abroad. Because ICT requires an understanding of Internet of Things (IoT), big data and artificial intelligence as predicting the future, we want to address the status of theory and actual Agriculture and propose future development measures. We hope that the study of the paper will solve the growing food problem of the world population and help the high productivity of Agriculture and smart strategies of sustainable Agriculture.

This paper discusses the state-of-the-art techniques in real-time state estimation for the Smart Microgrids. The most popular method used in traditional power system state estimation is a Weighted Least Square(WLS) algorithm which is based on Maximum Likelihood(ML) estimation under the assumption of static system state being a set of deterministic variables. In this paper, we present a survey of dynamic state estimation techniques for Smart Microgrids based on Belief Propagation (BP) when the system state is a set of stochastic variables. The measurements are often too sparse to fulfill the system observability in the distribution network of microgrids. The BP algorithm calculates posterior distributions of the state variables for real-time sparse measurements. Smart Microgrids are modeled as a factor graph suitable for characterizing the linear correlations among the state variables. The state estimator performs the BP algorithm on the factor graph based the stochastic model. The factor graph model can integrate new models for solar and wind correlation. It provides the Smart Microgrids with a way of integrating the distributed renewable energy generation. Our study on Smart Microgrid state estimation can be extended to the estimation of unbalanced three phase distribution systems as well as the optimal placement of smart meters.

Computational creativity is a field of artificial intelligence research to replicate creativity of human beings, creating works in various fields or helping human authors. The copyright of works produced by computational creativity has not been established in most countries yet, however, there will be the need for systems to protect the copyrights with the development of the technology in the future. In this paper, we propose a copyright protection system based on blockchain technology that protects the copyright of various contributors contributing to the creation of computer creative creativity, and transparently and safely records the contribution of copyrighted works. The proposed system records the contribution of all related works from the machine learning of computer creativity to the creation of the final work on the blockchain so that it is possible to establish quantitative evaluation criteria for the copyright when the future copyright law system is revised.
