This paper uses model-based fault analysis to identify the functions and factors that may cause miscommunication between supervisors and their subordinates. In describing the system model, a system-engineering approach is used to clearly define behaviors and interactions between supervisors and subordinates in the Japanese workplace. Semi-structured interviews were conducted to extract system requirements, and the functional architecture is described. The system model was verified by interviewing business persons. Using the system model, we identify the major functions and factors disrupting communication.

Enterprises and societies currently face crucial challenges, while Industry 4.0 becomes important in the global manufacturing industry all the more. Industry 4.0 offers a range of opportunities for companies to increase the flexibility and efficiency of production processes. The development of new business models can be promoted with digital platforms and architectures for Industry 4.0. Therefore, products from the healthcare sector can increase in value. The adaptive integrated digital architecture framework (AIDAF) for Industry 4.0 is expected to promote and implement the digital platforms and robotics for healthcare and medical communities efficiently. In this paper, we propose that various digital platforms and robotics are designed and evaluated for digital healthcare as for manufacturing industry with Industry 4.0. We argue that the design of an open healthcare platform “Open Healthcare Platform 2030 - OHP2030” for medical product design and robotics can be developed with AIDAF. The vision of AIDAF applications to enable Industry 4.0 in the OHP2030 research initiative is explained and referenced, extended in the context of Society 5.0.

The medical robotics market in the global healthcare industry have spread and extended in these several years. Internet of Medical Robotics Things (IoMRT) is also growing and Internet of Things is extending a new field of healthcare application. Whereas, the previous paper suggested that, in the field of robotics, the cloud platforms for Internet of Robotics Things (IoRT) were gradually developed; therefore, the digital platform and architecture for IoMRT of the healthcare industries should be formulated when necessary. An open healthcare platform for IoMRT is expected to promote and implement the robotics and the IoMRT applications for medical and healthcare communities efficiently. In this paper, we suggest that various medical robotics and the IoMRT-related applications will be designed and verified, while the open platform for medical, healthcare-related Robotics should be proposed and verified by the research initiative named “Open Healthcare Platform 2030–OHP2030.” In addition, the vision for enabling medical robotics and the IoMRT-related applications in the OHP2030 research initiative is explained.

Clinical Decision-Support (CDS) systems are architected to resolve knowledge-intensive tasks for supporting decision-making processes in the medical fields and the healthcare industry. Furthermore, CDS systems are expected to promote and contribute to the drug discovery process in pharmaceutical companies, while the CDS system can be connected and collaborated with electronic health record (EHR). However, current solutions for CDS are not well-established across different organizations and institutions in information societies because of high implementation costs and various, complex decision-making problems by medical staffs. In this paper, we suggest that the reference architecture and framework for the CDS system with EHR will be proposed and verified by the case in a hospital. In addition, the challenge and future activities for this area are expressed.

Many people today have trouble socializing and feel uncomfortable and unsatisfied with human relations. Additionally, people must accomplish their life goals within a limited time frame. Based on seminars held to improve skills for “living smart,” the authors felt that the social demands of living smart are increasing. This research attempts to visualize the skills for living smart in order to develop a methodology to improve these skills. An inductive approach clarified that “skills for living smart” comprise two factors: “entry into the environment” and “breakthrough strength.” We extracted seven components of “entry into the environment” (“participation ability,” “setup force,” “future force,” “antenna power,” “chameleon power,” “enchanting power,” and “cheerleading power”) and five components of “breakthrough strength” (“incredible ability,” “first impression ability,” “rising power,” “ability to grasp the heart,” and “boosting power”). We also demonstrated the continued effectiveness of the Seminar for Living Smart training. Visualizing skills for living smart are expected to facilitate future development of methodologies to improve these skills.

Nowadays, the globalization is rapidly increasing and many Japanese employees are going overseas. The first author has experienced assignment in the Philippines for globalization, but the first author had a stumbling block in work-related communication with the local workers and felt difficulty to adopt globalization. Our interviews confirmed that most Japanese IT workers assigned to the Philippines had similar experiences that the problem was difficult to take measures in advance. A sense of unease was revealed in surveys conducted in 2002 by Nishida on intercultural communication frictions in Japanese companies in the Philippines entitled “Japanese Cultural Differences Felt by Filipinos” and “Roles Sought From Japanese Bosses and Leaders by Filipinos”. Although many studies have been done on communication and interpersonal relations and it is often stated that conscious communication from the initial stages is vital to building interpersonal relationships, there are still few practical studies on the matter. Instead of initial stage communication, we focused on the first meeting conversation, conducted questionnaires on topics selection among Japanese and Filipino IT workers, verified differences in topic selection mutually using quantitative evaluation, and reported investigative results on possible reason why smooth interpersonal relationships could not be built from the initial stages.

Internets of Things (IoT) and Big Data applications and services have spread and are rapidly being deployed in the information services of the healthcare and financial industries, etc. However, the previous paper suggested that the current IoT services were individually developed, therefore, the open platform and architecture for the above IoT services of the healthcare industries should be deemed necessary, while the Big Data applications prevail in healthcare industry gradually. An open healthcare platform is expected to promote and implement the digital IT applications for healthcare communities efficiently. In this paper, we suggest that various IoT and Big Data applications will be designed and verified while the open platform for healthcare related IoT services should be proposed and verified by the research initiative named “Open Healthcare Platform 2030 – OHP2030”. In addition, the vision paper for enabling Digital Healthcare applications in the above OHP2030 research initiative is explained.

Graduate School of System Design and Management, Keio Universit yAbstract : The major challenge of designing public halls or performing arts centers in Japan is meeting the expectations of the regional community; greater stakeholder inv olvement is required in order to solve this problem. The purpose of this paper is to examine whether stakeh olders can become more involved in public hall design by using systems engineering (SE), which has never before been applied when designing public halls. As such, this study redesigned an actual public hall (Iw aki Alios) using an SE approach. The results revealed that applying SE was effective in the creation of a pu blic hall concept.Key Words : Public Hall; Public Theater; Design Process; Concept Design; Social System* 교신저자 : Saki Yoshihara, yoshihara.saki@keio.jp* This is an Open-Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License(http://creativecommons.org/licenses/by-nc/3.0) which pe rmits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

Several studies indicate that roughly 70% of the projects based on the software development have resulted in failure, thereby researchers and practitioners have been tried to develop solutions that will improve project success rates. It is insisted that to raise success rates, support should be provided by the organization to which the projects belong. With the aid of predictions that incorporate project outcomes for various information technology (IT) vendors, this study aims at identifying projects that should be preferentially supported by an organization. The data of 332 projects of various Japanese IT vendors were collected using an Internet survey, and a success/failure prediction algorithm is created by employing the Bayes classifier technique on the collected data. A resultant algorithm with 77.3% prediction capability was obtained. It is expected that the success/failure prediction procedure, including the prediction algorithm, help significantly to specify projects that an organization needs to participate in as priority.

Many recent communication studies show meaningful results using biometric information measurements, such as body movement with accelerometers. However, most of them could not describe the reasons subjects showed body movement due to the lack of measurement abilities in real time. This background has made researchers expect real-time measurement methods of brain functions with superior time resolution. In this research, we succeeded in confirming a new method of communication analysis by using the Kansei Analyzer, a simplified electroencephalograph (EEG), which measures brain waves in real time to obtain internal information from a human being. The results of our two experiments show that it was possible to find quantitative changes when using this instrument. It is especially noteworthy that the concentration of one subject and the interest of another were synchronized, thanks to the superior time resolution. Brain wave measurements with an EEG have illustrated the quality of communication and the human relationship as constituent elements of communication in real time.

It has become possible enough to take telemedicine by progression of the ICT. However, telesurgery is limited to experimental trials. This reason is that surgeon had been disturbed perceptual motor coordination by visual delay. This study was analyzed to understand about range of work efficiency in telesurgery with the delay. As a result of analysis, it was suggested that pointing task has threshold of the difficulty between 2 mm and 4 mm in diameter. The similar range in the work efficiency was up to approximately 300 ms independent on pointing size.

Hydroxyapatite (HAp) coated on titanium dioxide (TiO 2 ) thin films has been developed to supplement the defects of both TiO 2 and HAp. Thin films have been prepared by pulsed laser deposition (PLD) method using HAp and HAp(10%) + TiO 2 targets. X-ray diffraction (XRD) shows that there are many small peaks of Ca 10 (PO 4 ) 6 (OH) 2 crystal, and no impurity other than HAp is detected in HAp films prepared using pure HAp target. The composition ratio of the film was analyzed by X-ray photoelectron spectroscopy (XPS). HAp coatings on TiO 2 thin films have been prepared using HAp(10%) + TiO 2 targets. XRD and XPS measurements suggest that crystalline HAp + TiO 2 thin films are obtained by the PLD method using HAp(10%) + TiO 2 target.

Various kinds of high presence displays are developed and used in recent years. However, it is difficult to quantitatively evaluate the "presence". In this study, we tried to define the word of presence operationally by measuring the biological information of the users. In the experiment, the conditions of 2D/3D images, viewing angles, and resolutions of the displayed images were changed. And the electrocardiogram, facial skin thermo gram, and eye movement of the users were measured when they were looking at the displayed images. From the result, it was shown that the RRV value decreases, the nose skin temperature did not decrease, and the frequency of eye movement increased, when the user were looking at the high presence image. This situation means the state where the user is concentrating his mind, feeling relax, and being interest in the displayed image. From the results, we proposed the index value of the word of presence by using the RRV value, the nose skin temperature, and the frequency of high presence sensation.

The 70SnF2·30P2O5 glasses containing 25-500 ppm of fluorescein exhibit change in color from light yellow to reddish orange (absorption maximum, λ=500 nm) when heated at 240° C for 120-180 min. The fluorophosphate glasses also change the color from light yellow to reddish brown (λ=480 nm) when irradiated with 60Co γ-rays of 5×104 Gy. The P-F stretching mode observed in the Fourier transformed infrared (FT-IR) spectra showed an increase in peak intensity along with the coloration, suggesting a cleavage of the weak chemical bond between fluoride ions ( F-) and fluorescein molecules. The coloration is ascribed to change of the molecular structure of fluorescein from non-crystalline to crystalline type. ESR spectra of γ-ray irradiated 70SnF2·30P2O5 glasses showed a poorly resolved doublet, which was ascribed to a hole-trapped PO3F- center produced by electron scattering: PO3F2-→PO3F-+e-.
