This article proposes a novel approach to measure the performance of Safety-Critical Systems (SCS). Such systems contain multiple processing nodes that communicate with each other is modeled by a Petri nets (PN). The paper uses the PN for the performance evaluation of SCS. A set of ordinary differential equations (ODEs) is derived from the Petri net model that represent the state of the system, and the solutions can be used to measure the system's performance. The proposed method can avoid the state space explosion problem and also introduces new metrics of performance, along with their measurement: deadlock, liveness, stability, boundedness, and steady state. The proposed technique is applied to Shutdown System (SDS) of Nuclear Power Plant (NPP). We obtained 99.887% accuracy of performance measurement, which proves the effectiveness of our approach.

Objective : The objective of this case study is to search the effects of sensory integration treatment. First we have taken a child with a cerebral palsy and given him/her sensory integration treatment. Then, we intended to look into whether the child performed his daily-life tasks and how satisfactory the parents were with the treatment. Methods : We have chosen a child with a cerebral palsy and tested his sensory integration functions. Applying the 30 minutes-sensory integration treatment twenty times to the child, we compared the result of the treatment using Canadian Occupational Performance Measure. We counseled the parents of the child before and after the treatment. Results : We have rated the problems with the degrees of importance referring to the parents. Important problems include controlling eliminations, having meals, moving by self, interacting with peer groups, and performing delicate hand-movements. The score of the in the performance is 1.2 and the score of the degree in the satisfaction is 1.4 compared with the total score. Conclusion : We have concluded that the sensory integration treatment has the effective result to the daily-life task performances of a child with a cerebral palsy, a kind of sensory integration dysfunction and satisfies the child's parents after this case study.

With the increase of consumption of new renewable energy, the use of Electric Double Layer Capacitor(EDLC) is being gradually widened as the next generation energy storage device. In order to expand the market of EDLC which is recently receiving a lot of attraction as a new promising area, development of a charge/discharge cycle tester to measure and test performance, is essential. Therefore, this research designed a circuit to measure capacity and internal resistance and a circuit to measure voltage maintenance properties, based on EDLC's basic charging/discharging properties so it is able to measure the state of charge and discharge at high speed. When evaluating performance characteristics, the 5[V]/100[A] prototype-EDLC charge/discharge testing system developed for this research showed ${\pm}0.1$[%] of accuracy of voltage and current measurement. It was also proved that the developed charge/discharge testing system for EDLC can be applied to the actual industry, when testing the entire system using a program produced for data monitoring and acquisition.

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.

The performance evaluation of a new building is becoming more important because efficient design alone is often not sufficient to deliver an efficient building. However, there is a lack of standard evaluation methods to measure the energy performance of a new construction that has Energy Conservation Design Measures(ECDMs). This study presents an enhanced method based on calibrated whole-building simulation for evaluating the energy performance of new commercial buildings and demonstrates its use using a case-study building, including: an Energy Use Index(EUI) comparison with sub-metered data and an evaluation of the performance of specific ECDMs. The use of this method has determined that the case-study building was shown to use approximately 47% less energy than the base-case building that has the same shape and function as the case-study building(i.e., calibrated as-built simulation mode]), but doesn't include the simulated ECDMs.

The automation of agricultural machines is an irreversible trend considering the demand for improved productivity and lack of labor in handling agricultural tasks. Unstructured working environments and weather often inhibit a seemingly simple task from being fully autonomously performed. In this context, we propose a remote driving system (RDS) to aid agricultural machines designed to operate autonomously. Particularly, we modify a commercial speed sprayer for orchard environments into a robotic speed sprayer to evaluate the proposed RDS's usability and test three sensor configurations in terms of human performance. Furthermore, we propose a confidence error ellipsebased task performance measure to evaluate human performance. In addition, we present field experimental results describing how the sensor configurations affect human performance. We find that a combination of a semiautonomous line tracking device and a wide-angle camera is the most effective for spraying. Finally, we discuss how to improve the proposed RDS in terms of usability and obtain a more accurate measure of human performance.

Purpose: This preliminary study investigated a potential of the water wall systems that provide heat storage and natural lighting control simultaneously. Method: In order for transparency of the water wall to be controlled, the study first proposed two measures: to adjust transparency of the water wall; to control transparency of water wall surface. The performance of two measures then was verified and compared by experiments. In addition, a trade-off between heat collect and heat storage resulting from using additive for adjusting transparency was investigated. Result: The experiment showed that the two measures are similar in performance. The investigation of trade-off relation showed the additive should have the same heat storage as the water to prevent decrease in thermal performance of the water wall. As an economical measure to control transparency of the water wall, this study suggested a measure of secondary heat transfer systems using shading device that first absorbs solar radiation and then transfers heat to the water wall. The experiment show that performance of the proposed measure is similar to controlling transparency of water wall surface. In conclusion, it is expected that the performance of the water wall can be economically maximized by using the proposed mean in terms of heating, cooling and lighting energy saving.
