  • The rapid growth of complexity and scale can be witnessed in the design and development of modern systems. As such, the severity of damages in the occasional accidents has attracted great deal of attention lately. Although a variety of methods have so far been studied to overcome or reduce the disastrous results of hazards, the issues seem still persistent and even complicated due to the situation mentioned above. The concept of functional safety has been regarded as one approach to handling the matters by shifting up to the functions level from the consideration of each physical component itself. The outcomes of those efforts would be the international standards on functional safety such as IEC 61508 and its relatives including IEC 62278, EN 50128, ISO26262, and so on. In this paper, a method of how hazards can be analyzed to be coped with those standards has been studied. In the method proposed, the systems modeling language (SysML) is playing a key role to model and analyze the hazards from the viewpoint of functional safety. The approach taken has been applied in the analysis of the hazards in railroad systems. In spite of focusing on the individual components hazards, the method based on functional safety has analyzed them collectively with the added effect of identifying the cause originated from the interface between the functions.

  • Purpose: The purpose of this study was to examine changes in functional assessment measures (FAMs) and spatiotemporal gait parameters (STGPs) in healthy older adults before and after a 6-week intervention of a proprioceptive neuromuscular facilitation (PNF) training program. Methods: Thirty healthy older adults (mean age: $73.37{\pm}1.21$ age range: 65-79) were randomly assigned either to an experimental group (participating in a 6-week intervention of PNF training) or a control group (only performing daily activities). Participants in the control group did not receive any training program. Performance was assessed by recording changes in the FAMs and STGPs using functional assessment tools and GAITRite. Results: Participants in the PNF group showed significantly improved functional assessment measures and increased stride length, cadence, velocity, and step width (p<0.05). No significant differences in FAMs and STGPs were found in the control group (p>0.05). Conclusion: Participation in a PNF training program improves FAMs and STGPs, thereby increasing the ability of healthy older adults to maintain dynamic balance during functional performance and gait. These findings support the use of PNF training programs as effective fall-prevention programs for the elderly.

  • Red radish seeds were irradiated at doses up to 8 kGy using electron beam (e-beam) and gamma ray ($\gamma$-ray). The seed viability and functional properties (carotenoid, chlorophyll, ascorbic acid, and total phenol) of sprouts grown from these irradiated seeds were evaluated. High germination percentage ($\geq$97%) was observed in seeds irradiated at $\leq$5 kGy, but the yield ratio and sprout length significantly decreased with increased irradiation dose. Irradiation at $\geq$6 kGy resulted in curling of the sprout roots. Sprouting enhanced the functional properties of red radish seeds as indicated by the increased carotenoid, chlorophyll, ascorbic acid, and total phenol contents during germination. However, radiation treatment hampered the growth of seeds resulting in underdeveloped sprouts with decreased carotenoid, chlorophyll, ascorbic acid, and total phenol contents. In general, e-beam and $\gamma$-ray irradiation of red radish seeds showed similar effects on the seed viability and functional properties of sprouts. Postharvest storage reduced the functional quality of sprouts.

  • Purpose: The study sought to determine whether goal achievement, performance, satisfaction, activities of daily living, and gross motor function in children with spastic cerebral palsy are positive affected by goal-oriented functional task training. Methods: In a single case study, two 7-year-old girls diagnosed with spastic cerebral palsy were given functional task training based on individualized goals for 24 60-minute sessions over a period of 6 months. The individualized goals reflected the needs of both children and parents. The Canadian occupational performance measure (COPM) and the goal attainment scale (GAS) were used to measure goal performance and satisfaction before and after intervention. Independence of activities of daily living before and after intervention were assessed using the functional independence measure for children (Wee-FIM). And change of gross motor function were assessed using gross motor function measure (GMFM). Results: Clinically significant changes were observed in COPM and GAS, as well as positive changes in independence of gross motor function and activities of daily living. Conclusion: The findings indicate that goal-oriented functional task training addresses the needs of children with spastic cerebral palsy, which increases treatment satisfaction and has a positive effect on independent activities and participation in daily life.

  • Nd-Fe-B high performance magnets were prepared by die-upset forging. The effects of the deformation parameters on magnetic properties and flow stress were studied. Deformation temperatures in the range of $600{\sim}900^{\circ}C$ enable to achieve an effective anisotropy and temperature $800^{\circ}C$ proves to be suitable for deformation of Nd-Fe-B magnets. The amount of c-axis alignment along the press direction seems to depend on the amount of deformation and a saturation behavior is shown at deformation ratio of 75%. Magnetic properties are also related to strain rate, and maximum energy product is attained at an optimum strain rate of ${\varphi}=1{\times}10^{-2}s^{-1}$. By analyzing the relationship of stress and strain at different deformation temperature during die-upset forging process, deformation behavior of Nd-Fe-B magnets was studied and parameters for describing plastic deformation were obtained. Nd-rich boundary liquid phase, which is additionally decreasing the flow stress during deformation, is supposed to play the role of diffusion path and enhance the diffusion rate.

  • Objective: Setting therapeutic goals assist to identify patient priorities and predict problem that may arise in performing daily and functional activities. Goal setting is associated with improved rehabilitation outcomes in individuals with hemiparetic stroke. This study was conducted to assess the effects of having awareness and satisfaction of goals on the functional status of individuals with hemiparetic stroke. Design: Cross-sectional study. Methods: Eighty-one people who had been diagnosed with stroke participated in this study. The study was conducted through a face-to-face surveys to identify participants' awareness and satisfaction of goals and standard assessment tools were used to evaluate patients' functional status. This study measured functional status through three clinical measures including the manual function test (MFT), Berg Balance scale (BBS), and modified Barthel index (MBI). Results: In participants with hemiparetic stroke, the MBI, BBS, and MFT scores were significantly higher in the participants who were aware of the therapeutic goal than in those who were unaware (p<0.05). The MBI, BBS, and MFT scores were not significant between the participants who were satisfied with the goal and those who were unsatisfied. Conclusions: This study suggests that having awareness in therapeutic goal-setting could lead to improvement of functional status in those with hemiparetic stroke. This study highlights how goal-setting can have a positive effect on persons with hemiparetic stroke.
