The authors studied the outcomes of calcaneal lengthening for the treatment of planovalgus foot deformity in ambulatory children with cerebral palsy (92 feet in 56 children, mean age 9.2 years), attempting to define the surgical indication in terms of the severity of the foot deformity. Sixty-nine cases (75%) showed satisfactory clinical outcomes at an average follow-up of 5.2 years (range 4.0-17.2 years). Gait parameters such as foot progression angle, ankle motion in sagittal plane, and its po

The paper discusses a multi-agent system for robot-soccer. The system consists of a supervisory controller, and controllers for attack, defense and goalie robots. Real time vector field based path planning, Petri-net theory and Q-learning technique are used in the design. Robot-soccer system has a dynamic environment. A soccer robot has to take an appropriate decision based on environment situation. The supervisor assigns the role of each robot. Experimental study verifies applicability and effi

Smart sensing and power line tracking is very important in a smart grid system. Illegal electricity usage can be detected by remote current measurement on overhead power lines using an inspection robot. There is a need for accurate detection methods of illegal electricity usage. Stable and correct power line tracking is a very prominent issue. In order to correctly track and make accurate measurements, the swing path of a power line should be previously fitted and predicted by a mathematical fun

This study examined how demographic information, chronological age, older adults’ physical and mental health, and basic psychological needs affected travel intention. The survey samples were collected from 577 adults, all over 60 years of age. A hierarchical multiple regression analysis was used to test the proposed hypotheses. First, demographic information with chronological age was used for primary analysis. The outcome indicated that chronological age was negatively associated with travel in

Intracranial wooden foreign bodies are rare. In addition, such objects are difficult to identify with conventional radiographic techniques, such as X-ray radiography or brain computed tomography. A 48-year-old man presented to our emergency room with a headache. Even though he had a history of trauma, he had no external wounds and showed no neurological deficits at the initial examination. He was initially diagnosed with trauma-related pneumocephalus. He developed a delayed intracranial infectio

In recent years, there has been increasing interaction between humans and non-human systems as we move further beyond the industrial age, the information age, and as we move into the fourth-generation society. The ability to distinguish between human and non-human capabilities has become more difficult to discern. Given this, it is common that cyber-physical systems (CPSs) are rapidly integrated with human functionality, and humans have become increasingly dependent on CPSs to perform their dail
