    This study aims to consider the theoretical positions and relationships among the theory of customer experience by Bernd H. Schmitt; the Kansei information processing process proposed by Kansei engineering and Kansei science; and the three elements of Emotional Design by Donald A. Norman. Through case studies, we also consider what kinds of design processes exist and how these processes can affect the customer’s experience, which is difficult to manipulate in terms of product design in product development. In conclusion, we have considered and analyzed the process of design of products and services by focusing on the customer experience. The experience of customers, which is difficult to manipulate and control, has been clarified, and it is possible to implement product design in such a way as to realize the experience of the assumed customer. In addition, in this study, we have made suggestions about product design and the design process, focusing on the customer experience itself, as well as the related research and business.

    Clinical trial data is acquired in an environment where noise factors (characteristics of patients, fam-ilies, doctors, hospitals, etc.) are controlled in order to verify scientific hypotheses. Real world data, on the other hand, is accumulated through daily activities that do not control noise factors. However, previous clinical trials in Japan valued the significance of not eliminating noise factors. I would like to consider the potential of health data science by reevaluating the underlying philosophy..

    Since 2005, the science of such artifacts as enterprise was mainly concerned with its physical-cyber aspect at IE&OR. This paper is further focused on its informational aspect, and gives the similar property to the physical-cyber artifacts at the pair-hierarchy view. First, the inequality of integration (Muda) vs. sharing (efficiency) is proposed and discussed on the base of information theory. Next, this numerical and harmonic solution would be given to and discussed with the case of correlation table in the class of pair-matrix. Finally, the rule (criterion) of efficiency (0.6) vs. Muda (0.4) is re-considered and re-evaluated under the coming knowledge-management society, in the vicinity of black-hall (kernel).

    A supply chain is a system consisting of different entities, which add value from the original resource sources to the final products for customers. Although each entity is indispensable to construct a supply chain, the degree of importance of each entity varies depending on the role played in the supply chain. In this paper, we assume that the information produced by the entity that plays more important role should be referred more by other entities for making appropriate decisions to effectively operate the supply chain. Namely, we develop index and a method that evaluates the soundness of the supply chain based on the structure of its information network using the Analytic Hierarchy Processes (AHP). Besides, we show a design method to search the ideal structure of the information network in supply chain. We inspect the effect of a suggested method using simple supply chain model and evaluate supply chain that we introduced a production seat booking system having platform structure built-in more into as an example.

    The aim of this study is to investigate the cutting phenomenon under ultrasonic vibration-assisted cutting condition. The vibrating cutting edge is considered to be cause of dynamic change of cutting force at ultrasonic frequency. However many researchers have explained the effect of ultrasonic vibration-assisted cutting by evaluating the time-averaged cutting force, because it is difficult to measure the dynamic cutting force by using dynamometers. In this study, the instantaneous stress distribution on workpiece was visualized by photoelastic method in combination of pulse laser emission synchronized with vibration of cutting edge. Orthogonal cutting test was carried out at low cutting speed relative to vibration speed of insert. A constructed photographic system divided the ultrasonic vibration period of 36.2 μs into 360 points and took one photograph frame at each point. By counting the number of criteria pixels which images the cutting stress, the intermittent cutting condition was evaluated. It was experimentally confirmed that the stress distribution under vibration-assisted condition showed the periodical change synchronized with insert vibration. The intermittent cutting condition was affected not only feed rate but also depth of cut. The theory of relative motion between blade and work is insufficient to explain these results. Therefore remnants formed due to elastic deformation of the workpiece were examined. The vibration cutting dramatically reduced the elastic deformation and the vibration amplitude had effect on the amount of remnant thickness.

    Tribological properties such as lubrication, friction and wear resistance are important for mechanical engineering to improve machine operating efficiency, machine performances and machine life. To improve the tribological properties, surface texturing methods are available such as scraping. Scraping fabricates many small depression on target surface evenly, the depression will act oil hole to promote lubrication performance. Many researchers have reported the surface texturing method to employ fast tool servo, turn mill processing and digital data based texture machining. This paper reports a surface texturing method by ultrasonic vibration turning to improve tribological properties. In ultrasonic turning, cutting tool is vibrated in principal direction and radial direction simultaneously. The radial direction tool vibration acts to dig up or to push workpiece surface in radial direction periodically, textured surface will be obtained. In order to evaluate the tribological performance of the turned surface, friction coefficient between stainless steel pin and turned surface were measured under oil dipping condition. It was confirmed that friction coefficient of ultrasonic turned surface is reduced compared with ordinary turned surface. Another effects of ultrasonic turning that hardness and wear resistance property of turned surface improvement were observed in this research.

    This e-portfolio system was developed to support self-monitoring and stress management in rea-sonable accommodation. One of the features of this system is that heart rate information is used as an objective judgment material of stress for participation in the activity of ICF environmental factors, which is a subjective judgment material of the situation. In order to obtain this heart rate information, we used an optical wearable terminal that is less accurate than the electrode type in consideration of non-invasiveness to various needs in daily life. Furthermore, Onomatopoeia based on ICF was used for subjective data entry. Onomatopoeia can eas-ily express internal emotions and internal senses and is widely used in the classification of emotional expres-sions. This onomatopoeia icon input makes it easy to accumulate subjective judgmental materials regarding stress factors, and supports continuous self-monitoring and coping for users.

    “Tonarigumi”, “Chounaikai”, and “City Association” organizations have worked as a mechanism for distributing services to local residents. Recently, the external environment is changing. In addition, there are areas where these organizations have disappeared due to old town planning. In many cases, the community “shopping association (shopping district)” has taken their place of them, however when the store is succeeded, they entrust an external developer, and the town planning can be conducted without considering the lives of the local residents. Quantiative research is conducted. From a sustainability viewpoint, we will consider the current situation and propose solutions.

    There are novel structures of society such as Industry 4.0 and Connected Industries. Under these structures, a novel safety management system considering man-machine interaction is very important topic. It seems that direct and quantitative validity of risk assessment and risk reduction measure such as reinforcement of safety behavior and/or reduction of unsafe behavior is now not sufficiently accomplished. Some quantitative assessment for residual risks focusing on worker's behavior is necessary. We introduce a principle of Behavior-Based Safety (BBS) which might be applicable to reduce residual risk for safety of workers. BBS, focused on behavioral modification using principle of reinforcement, is one group of Behavior Analysis of Psychology. Goals of BBS is prediction, control and quantitative measurement of target behavior. Here, we introduce BBS.

    As a method to analyze the safety of software systems, “STAMP” is drawing attention. This is an accident model focusing on the interaction of modules and control, and enables more rational assessment than that obtained by FTA or FMEA, which are conventionally used programs for software safety assessment, etc. Safety and reliability assessment of a whole railway system is required to satisfy RAMS standard (IEC62278), where quantitative analysis is needed for assessment of safety. In this paper, we will take examples of conventional safety analysis for railway signaling, organize the characteristics of these analysis methods and describe the procedures to effectively take advantage of each analysis method for assessing the safety of a railway system.

    This paper proposes the new methodology to verify safety of black-box type of artificial intelligence (AI) such as deep neural network (DNN). In the proposed methodology, the following two key technologies are used:
     FRAM (Functional Resonance Analysis Method)
     SpecTRM (Specification Tools and Requirement Methodology)
    FRAM will be used to visualize the hidden internal logic inside the DNN which is supposed to be acquired during the machine learning (ML) process.
    SpecTRM will be used to analyze the ML test result and tune-up/validate the FRAM model to show completeness of the ML and consisitency of the learned DNN model.
    By this study, the following findings were acquired:
    1) The hidden internal logic of DNN system can be effectively visualized by FRAM by its rich modeling capability to define timing, preconditions and postconditions.
    2) Formal method technology (SpecTRM) can be used to check consistency of the FRAM model and validate that the learned AI logic is understandable by human.
    3) Formal method technology (SpecTRM) can be used to check completness of the ML by confiming full-path testing is completed and by identiying all missing test casees.
    4) The proposed methodology can be utilized not only by black-box type of AI, but also applicable to white-box type of AI such as random forest systems.

    The quarry site at the Miyagase Dam is a slope of 4.8 ha in a harsh environment with a steeply inclined bedrock base for the growth of plants. In 1995, 70,000 seedlings of broad-leaved medium-and-high trees considering biodiversity were planted using the pot seeding planting method. To verify the effect of this vegetation, we conducted follow-up field surveys on the growth of trees in 2001 and 2007, and confirmed that the ecological transition of trees as a whole is progressing smoothly. In July 2018, 23 years after planting, we attempted an aerial survey of the entire slope using a UAV (unmanned aerial vehicle). The result of this survey confirmed that the slope planting approached the climax vegetation in the ecological transition. Although slope planting with trees is expensive, there are carbon dioxide fixation effect, biodiversity conservation effect, etc. that are not found in planting herbs.

    There is a strong need for explanation model development and selection (especially, partial differ-ential equation : PDE) using big data from interesting phenomena. In the inductive PDE derivation from big data, at present, the PDE computation results have been regarded as big data in order to establish a methodolo-gy. Assuming that a PDE is a linear regression model composed of partial differential terms, the coefficients are estimated by regression analysis, and the difference (error) between the true and the estimated coefficients is minimized. In the conventional method, since the partial differential term is calculated by differential ap-proximation, it is difficult to analyze the cause of the error.
    To solve the problem, we take PDEs with exact solutions and compute the partial differential term by differen-tiating the solution analytically. Considering that PDE does not depend on initial conditions, we hypothesized that the error is caused by insufficient comprehensiveness of the initial conditions. For the exact solution of the advection-diffusion equation with system noise superimposed, we calculated the error relative to the true value of the coefficient. The exact solution was calculated by changing the initial conditions at random, and we con-firmed that a negative correlation between the number of initial conditions and the error.
