Osaka Gakuin University , also known as Osaka Graduate University , is a mid-sized, mid-level private liberal arts university located in Suita, Osaka Prefecture, Japan. The university focuses on law, economics, and international studies, but still provides a wide array of other subjects for study. Wikipedia.

Experiences of teaching under-graduate students and training industrial engineers on how to think creatively in problem solving are reported. The contents are based on the TRIZ methodology but have been further reorganized and unified into USIT (Unified Structured Inventive Thinking) for easier to learn and apply. Case studies, published by engineers in technologies and obtained by students for everyday-life problems, are found useful in both teaching/training situations. © 2011 Published by Elsevier Ltd.

The decision version and the computational version of the subset sum problem are known to be NPcomplete and NPhard, respectively. The conventional knapsack schemes are based on the difficulty of the computational version of the subset sum problem. In this paper, we shall propose a new knapsack scheme which is based on not computational version but on decision version of the subset sum problem. In the proposed scheme, the public sequence would be indistinguishable from uniformly distributed sequence. We shall discuss on the security of the proposed scheme and show that the proposed scheme is secure against the conventional attacks. © 2012 IEICE Institute of Electronics Informati. Source

Parallel-link robots, in general, possess high power and high precision owing to the parallel arrangement of actuators; however, their workspace is smaller than that of serial-link robots. In this paper, we develop a parallel-link robot prototype with pneumatic actuators in which a mechanism for varying the actuator inclination is incorporated for the purpose of enlarging the workspace. Our parallel-link robot realizes the rotational and translational motions of the end effector principally by the linear reciprocating motions of pneumatic linear drives mounted on the base. Auxiliary pneumatic actuators are used to adjust the inclination angles of those main pneumatic linear drives. The use of pneumatic actuators to realize the proposed parallel-link robot results in lightweight, compact, and low-cost construction. The workspace and motion transmissibility of our parallel-link robot are analyzed through simulations based on kinematics; then, experimental investigations are carried out using the prototype. © 2014 IEEE.

In our previous work [12], [13], we introduced generalized feed-forward shift registers (GF2SR, for short) to apply them to secure and testable scan design, where we considered the security problem from the viewpoint of the complexity of identifying the structure of GF2SRs. Although the proposed scan design is secure in the sense that the structure of a GF2SR cannot be identified only from the primary input/output relation, it may not be secure if part of the contents of the circuit leak out. In this paper, we introduce a more secure concept called strong security such that no internal state of strongly secure circuits leaks out, and present how to design such strongly secure GF2SRs.

Thus far, peoples attitudes toward biotechnology and genetically modified (GM) crops have been investigated in the European Union, USA, Japan, and other nations. However, direct comparisons between peoples attitudes toward conventional plant breeding crops and their attitudes toward GM crops will show the characteristics of peoples attitudes toward GM crops more clearly, and this will bring about valuable suggestions considering risk communication about GM crops. The first purpose of this study was to show attitude gaps between conventional plant breeding crops and GM crops. Referring to preceding studies related to the acceptance of biotechnology, a causal model was constructed to predict the acceptance of GM crops and plant breeding crops. Four factors-perceived risk, perceived benefit, trust, and sense of bioethics-were set up as important psychological factors determining the acceptance of GM crops and plant breeding crops in the structural equation models. The second purpose of this study was to verify the validity of these causal models. A social survey was administered in Tokyo, Japan, with a sample of 600 men and women aged 20 years or older who participated. The results showed that people have a more negative attitude toward GM crops than toward conventional plant breeding crops in every factor, that is, perceived risk, perceived benefit, trust, sense of bioethics, and acceptance. The plausibility of the causal models was tested by using structural equation modeling, and the results indicated that the four factors explain the acceptance very well in both models. Moreover, although perceived risk is the most important factor in the acceptance of GM crops, trust is the most important factor in the acceptance of conventional plant breeding crops. © 2013 Taylor and Francis Group, LLC.
