Smart TV is expected to bring cloud services based on virtualization technologies to the home environment with hardware and software support. Although most physical resources can be shared among virtual machines (VMs) using a time sharing approach, allocating the proper amount of memory to VMs is still challenging. In this paper, we propose a novel mechanism to dynamically balance the memory allocation among VMs in virtualized Smart TV systems. In contrast to previous studies, where a virtual machine monitor (VMM) is solely responsible for estimating the working set size, our mechanism is symbiotic. Each VM periodically reports its memory usage pattern to the VMM. The VMM then predicts the future memory demand of each VM and rebalances the memory allocation among the VMs when necessary. Experimental results show that our mechanism improves performance by up to 18.28 times and reduces expensive memory swapping by up to 99.73% with negligible overheads (0.05% on average).

A small, highly-trained crew working on the ship's automation has contributed to the improvement of operation efficiency and the labor environment on board ship. However, at the same time, having a small crew adds more responsibility to the ship's officers to safely operate and manage the ship. Recently, development on the system to concentrate important information being scattered at the various pieces of navigational equipment has been actively studied, using information and computer technology. The purpose of this study is to set up and implement an integrated marine data networking and communication system on the training-research ship. Information relating to navigation, engine and office automation were investigated and analyzed, and implementation methods associated with navigation, engine and the management information system were designed and presented. In addition, the networking system and navigational signal interface unit for the integrated communication system, and the data communication method between the ship and land are also discussed.

In spite of the rapid increase of computer use in our everyday life, not much effort is undertaken to take measures to prevent Musculoskeletal Disorders(MSDs). In this paper, we suggest a movable armrest which would lower the exposure to the MSDs, especially on the vicinity of arm. The aim of this study is to determine whether there are differences in wrist angle variations, forearm muscular loads, comfort and normal performance between the invented movable armrest and a conventional armrest when using a computer mouse. Eight experienced VDU workers performed a standardized simple task set which consists of 15 detailed tasks with each armrest. The wrist angle variations in the right arm were registered by electrogoniometer and the muscle activities in the shoulder, deltoid and two extensors in the forearm were also registered by electromyograph. The subjects rated perceived comfort while performing the tasks with each armrest. Working with the invented armrest, compared to general, gave significantly decreased wrist angle variations at most of the detailed tasks of both biaxial movements. Moreover, as the distance of targets increased, the difference of muscle activities in two different situations trend to be increasing. At the same time, in work with invented armrest, the subjects rated more comfort and they showed decreased normal performances in 8 detailed tasks which were mainly caused by macro moving time.

Team activities in engineering curriculum play the major role in nourishing students with problem-solving and team-working capabilities. Educators endeavor to guide students to achieve success experiences through team activities. The sense of success depends on how the students think and feel about team activities. In this study, we investigated the students thoughts on team activity in various aspects. We provided freshmen and juniors with a set of questionnaire and gathered answers, from which we tried to elicit implication that we may apply for coaching their team activities. The analysis result shows that the perception level of freshmen on team activities is less mature in a sense that the freshmen's view is more neutral than that of juniors. Regardless of the grade, they show that they put more emphasis on the team atmosphere than on the team performance. Especially the freshmen are more sensitive to the relationship between the team members than the juniors. The juniors concern more about whether they prepare well enough for the team activities or not. Both of the grades prefer self-regulation in team formation and think the leadership is essential in performing team activities. However, they both hesitate to take a role as a leader. We expect the research result will provide novel ideas for coaching students to obtain valuable experiences on team activities.

An efficient laparoscope manipulator robot was designed to automatically control the position of laparoscope via a passive joint on end-effector position. The end position of the manipulator is controlled to have corresponding velocity defined in the global coordinate space using laparoscopic visual information. Desired spatial position of laparoscope was derived from detected positions of surgical instrument tips, then the clinical viewing plane was moved by visual servoing task. The laparoscope manipulator is advantageous for automatically maintaining clinically important views in the laparoscopic image without any additional operator. A laparoscope is mounted to a holder which is linked to four degree of freedom manipulator via universal joint-type passive rings connection. No change in the design of laparoscope or manipulator is necessary for its application to surgery assistant robot system. Expanded working space and surgical efficiency were accomplished by implementing slant linking structure between laparoscope and manipulator. To ensure reliable positioning accuracy and controllability, the motion of laparoscope in an abdominal space through trocar was inspected using geometrical analysis. A designed laparoscope manipulating robot system can be easily set up and controlled in an operation room since it has a few subsidiary devices such as a laparoscope light source regulator, a control PC, and a power supply.
