    This study deals with design method of smart products based on IoT and DX. In the resent economic situation, we know the valuable performance of the smart products is affected by valuable services supplying consumers when the smart products are used. In this study, we propose the method to generate highly novel service and to design the service and a product to supplying the service. The proposed method is composed of two types of process: the process of generation and development of new service business and the process of design of smart products productively supplying the services. In the method, Customer Journey map is performed to evaluate the persona’s activity, and multiple types of services are generated by using data included in the map and functional deployment process. In addition, we develop the system for generation of new novelty services by language analysis of sentences related to the past designs collected in the data base. In order to evaluate the effectiveness of the proposed method, we applied the method is examined in the educational program for undergrade students in our university. In this paper, we explain the characteristics of the proposed method and the results obtained from the educational program.

    Supply chain (SC) entities, such as retailers, wholesalers, manufacturers, supplier and others, store and/or produce information on demand, capacity, inventory, and so on. Supply chain management (SCM) can be performed by using such information. Namely, it is critical for successful supply chain management to build an adequate information network among entities to acquire necessary information. However, there has been almost no quantitative method to evaluate the adequacy of the information network in a supply chain. Therefore, we develop a method that quantitatively evaluates the adequacy of an information network for managing a supply chain. The method divides the information network into several sub-networks based on the type of information. Each sub-network is evaluated by the sub-network evaluation index, which is calculated as the sum of the absolute differences between the rank of importance of each entity in the sub-network and the rank of its own information referred to by other entities in a sub-network divided by the maximum sum of the ranking difference value for the number of entities in the supply chain. Then the information network is evaluated comprehensively as the evaluation index SCV, which is calculated as the sum of the weighted value of each sub-network evaluation index. The effectiveness of the proposed evaluation method is examined in the case of SCM of the production company which applied a production seat system.

    People have both expectations and fears about current AI, which has begun to be integrated into our society through products and services. However, Generation Z, who has been around digital device such as smart phones since they were born and have a new sense of values, will play a leading role in the future society in which AI and people collaborate. Therefore, it is necessary to understand the expectations and fears about AI from their own words.
    In this study, we conduct a questionnaire survey on current AI for Generation Z and text mining to extract information from a large amount of text data, and discusses the research and challenges involved.

    We introduce the study on the evolution of cooperation that we have been working on so far, and we discuss what kind of insights which can provide to the post-corona society. A purpose of the evolution of cooperation is to answer the question of why people cooperate. In both with-corona and post-corona societies, the theme of how to promote people's cooperative behavior has been continuing to be highlighted as a socially quite important issue. This paper introduces the construction of behavioral models during the infectious disease epidemic, infection prediction and social policy designing using agent-based simulation, and the formulation of a realistic structure of information distribution with a network structure. We hope that the theory and experiments will approach the prevention of infection and the solution of problems in the post-corona society by clarifying the features of effective incentives and institutions.

    A pandemic of a VOCID-19 emerged with uncertain information about an unknown virus, making it difficult to determine what information was correct, especially in the early stages of the pandemic, and various problems arose. As the term “infodemics” was used, confusion caused by information became a social problem as much as confusion caused by viruses. In particular, social media has been the focus of much attention, and the uncontrolled spread of information by social media has become a social problem. In this presentation, we clarify the actual situation of information diffusion, including fake news, and show that social media has contributed to the diffusion of correct information to a certain extent.

    The United Nations Security Council is one of the primary organs of the United Nations, which is primarily responsible for the maintenance of international peace. It is also a significant battleground for great-power politics where the permanent members of the Council (the United States, Britain, France, Russia, and China) constantly engage in mutual confrontation and cooperation. This study analyzes the official meeting records of the Council using large-scale text analysis methodologies such as word embedding. Focusing on one of the most consequential notions for the Council deliberations, ”threat to the peace,” the study quantitatively represents the members’ conceptions concerning this notion, and rigorously measures the discrepancies among these conceptions. The study thus clarifies how the polarization among the major powers has unfolded over the past decades.

    We define the residential areas of new and old residents based on the age of the properties, and visualize and model the spatial interaction between new and old residents in the town during the daytime using location data collected through a smartphone application. By measuring the daytime human mobility flow and diversity of the population in each area using entropy, we can visualize the spatial segmentation between old and new residents. We propose a human mobility model based on the statistics of the outing rate, the time spent in each place, and the network of human flows connecting the origin and destination places of the movement. We also propose a recommendation system for places and facilities, which gently improves the segregation in the human flow network. These will provide scientific support for local policies in creating communities where new and old residents cooperate with each other.

    Trust and relief for prevention originate from reliability that leads to purpose setting-decision making-action. Also they have deep relations with the social system(security system etc.)such as PCR test and medical care system to be seen in Covid-19, the support system and the behavior pattern. Moreover, we have common understanding that the life and the action in the era of corona coexistence have been greatly influenced by philosophy and ethic including the value and meaning of the human being existence. This fact is similar to the case when we assure trust and relief to our users in the age of the Fourth Industrial Revolution including IOT, Robot, automatic driving car and AI. This presentation proposes ①the structure of trust and relief, ②seven view-points of culture for safety,③seven view- points of rule for safety, based on previous researches, all of which are evaluated as “Meta prevention for trust and relief”. In addition, the East-West philosophical and ethical thought behind the above proposed models is shown to be effective for meta prevention through the illustration and the description such as Covid-19 seesaw model.

    The Just-In-Time (JIT) production system is a production system that supports production of many models in small quantities as opposed to a planned mass production system. This system, which has been developed for many years mainly by Toyota Motor Corporation, has two pillars: Just-In-Time and autonomation, and is made from a flow in which a later process takes what is needed from an earlier process, starting from product demand, in terms of inventory and intra-process logistics. These have been studied and applied worldwide, and are affecting industries in the United States and other countries, through methods such as Lean production system and Six Sigma (6σ). Japan Association for Management Systems recommends the JIT production system for Kototsukuri-Collection.

    Recently, we have been developing a system that automatically acquires tactics and strategies of the table tennis match from broadcast video. In this system, the input and output data are constructed by automatically extracting the ball position and the player position from the broadcast video. During the match, an algorithm removes noise and estimates the ball and player position. In this paper, we introduce the motion tracking system. In the motion tracking system, the ball trajectory and player position are automatically extracted from the 30fps broadcast video and converted into two-dimensional coordinates. The ball trajectory is estimated by preprocessing with the white blog extraction process and RGB extraction process, and then the player’s skeleton position is estimated by CenterNet of deep learning (DNN). The position of the ball hidden at the body is estimated using the Kalman filter and the bicubic interpolation method. Finally, we discuss the future image of this system which acquires the table tennis strategy and makes the strategy visible to directors and coaches using the if-then rule by fuzzy ensemble learning.
