We have been implementing the research work in order to achieve the rural clinics that can provide the similar quality of clinic performance as that of urban general hospitals. The research work involves the use of common fund in community, from the financial viewpoint, for the purpose of continuous management of clinics in rural villages of developing countries, and the introduction of telemedicine system from the viewpoint of medical quality improvement. Our research fields have been rural villages near Hanoi, Vietnam1). This report is a result of another research work concerning the telemedicine for the clinics of rural villages, covering from the introduction of the vertical integration-type medicine management pursuing the possibility of quality improvement measures in the healthcare at the Vietnamese rural villages through the field research at the Hanoi, the capital city of Vietnam as well as the hub of the IT technology.

Designing amorphous systems is challenging because of the broad scope of the task. The design team must integrate various solution elements, such as hardware, software, service, and infrastructure, while resolving the communication challenges among different domain-experts. Scenario-based Design for Amorphous Systems enables design teams to effectively deal with ambiguity and to communicate their ideas among team members and managers, as well as with customers through a common language. We validated its effectiveness in both academia and industry. This paper describes the process and the preliminary results of the validation based on three approaches: Statistical, voting and interviews. © 2010 by Sun K. Kim.

We investigated medical practitioners laws in the United States, Japan and Taiwan, each country's limits and barriers against telemedicine existed. Therefore, we tried to prove that our proposed high-realistic video communication systems can overcome the legal limitations. According to experiments, we concluded that GI-POF is a useful solution of improving telemedicine. Evidence showed that it supports transmit noncompressed Full HD images since the keys are real-time and authenticity of image.

Specifically, an optical simulation using Zemax OpticStudioTM [2] is conducted to understand the influence of axial and angle misalignment of the optical module with the Ballpoint-pen connection.

We will report the problem point and the issue of the wiring for residence, and then reveal that the Plastic Optical Fiber is very suitable for the wiring of the home network of recent date. And we report that our newly developed PCP GI POF (Partially chlorinated polymer based GI POF) will be just fit to wire in the house. It has several features such as high-bandwidth, large core diameter, high numerical aperture, and high thermal resistance. © 2012 ICPOF.

We describe an internet consultation and remote conference system designed to improve the quality of medical care in rural areas [1]. The system employs telemedicine to conduct virtual conference consultations, enabling doctors to provide their opinions and offer solutions to clinical problems, thereby providing healthcare to an aging society. In order to enjoy a long life through the stages of aging, a healthy and active lifestyle is necessary. In recent years, the use of ICT (information and communication technology) has become increasingly popular among seniors. In view of the changing communication environment, we used an application in which both high-speed GI-POF (graded index plastic optical fiber) network and flexible cable materials are required. We also considered the idea of spirituality while providing remote medical consultations to an aging society through ICT.

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.

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.

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.

A 10GBASE-SR(IEEE802.3ae) network [1] using 16km total length graded-index plastic optical fibers (GI-POF) [2∼6] was installed in a new building of Keio University completed in January, 2014. The optical network enables to communicate ultra-high-definition (UHD) video traffic for the university's increasing demand of education and research activities using high quality moving pictures. Because no standard for GI-POF cabling system has ever existed, quality guarantee was one of the biggest concerns for the GI-POF maker and users. To reduce the risk, we established a network configuration, and also set criteria of the BERT (Bit Error Rate Tester) characteristics and the frequency response based on previous studies. The GI-POF cables were inspected in accordance with the new criteria in advance to the building installation, and the network performance was evaluated after the installation. As a conclusion, the new evaluation method of 10Gbps GI-POF cabling system for the building installation was verified.

We have developed an optical I/O connector embedded using optical collimator lenses fabricated with well-defined and proven ball-point pen technology. The collimator lens consists of a glass-ball lens and a plastic optical fiber (POF) in a ball-point pen type metal sleeve. The POF is point-crimped in the sleeve without any adhesives. This enables a reliable fiber assembly without any damage to the POF, because the sensitive fiber end-facet is protected by the surrounding glass-ball and metal sleeve. The coupling loss is as low as 3dB, including Fresnel losses between engaged plug and receptacle collimator lenses. This optical I/O connection scheme has encouraged us to promote the POF as a cost-effective interconnection medium into the consumer electronics market. © 2012 ICPOF.

A micro optical collimator using the world's fastest GI POF and ball-point pen manufacturing technology was developed for future consumer electronics applications which require high speed and ease of use optical communication. However, because of the metal sleeve of the ball-point pen component, inside of the sleeve was invisible and hard to know the accuracy of precise assembly without destructive quality check. We evaluated relationship between the degree of output beam spread and the distance of lens and fiber using the sleeveless measurement apparatus and understood that beam spread angle could tell the accuracy of precision assembly. The assembling techniques and conditions of the optical micro-collimator adopting ball-point pen technology were optimized and confirmed as highly precision assembling of ±0.01 mm accuracy of the distance between ball lens and GI POF.

案件の複雑化や新規事業創出のため、企業内の連携や協業が近年、ますます重要視されるようになってきた。さらにバックグラウンドを持つ人々の連携や協業を促す方法論として、ダイアローグの理論及び実践の発展が2010 年代に入り注目を集めている。本研究では対話研究の中でもとりわけ連携及び協業における創発性が高いGenerative Dialogue(GD) (Isaacs 1999: 38-41) に着目し、システムズエンジニアリングの手法を用いた設計方法を提案し、その有効性を定性的及び定量的に検証した。具体的な設計モデルの構築に当たり、機能設計レベルではGDに必要な機能として、対話に参加する機能、他者と連携することに積極的になる機能、参加者の高揚感が高まる機能、参加者が一体感を持つ機能、並びに参加者のパフォーマンスを出す機能の5 つを特定した。そして、物理設計レベルにおいて、この5 つの機能を用い、企業内で展開可能な、GD を生成するワークショップを設計した。さらに、提案したGD 設計の有効性を定性的及び定量的に検証するため、日本の中小企業の典型的存在と目される企業において、本研究により設計したGD 生成ワークショップを実施し、参加者の参与観察、PANAS、協調的幸福感尺度、並びに参加者の発言のテキストマイニングにより、定性的及び定量的に同ワークショップの有効性を示した。また、企業の現場でワークショップを実施し、参加者から高い満足度を得たことで、今後企業等で連携及び協業の促進のためにGD生成ワークショップが複製性のあるモデルとして展開できる可能性を示した。

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.
