The ankle plays a very large role as an end effector in gait and leg erection. As the number of people with reduced mobility in the ankle joint due to aging and nerve damage increases, rehabilitation ...and related research are steadily increasing. However, most studies overlook the eversion action that plays an important role in stability. In this study, an intention detection algorithm including the eversion motion was developed, and a multi-channel EMG sensor module was developed and utilized. By moving the ankle in a specific direction, 36 channels of EMG signals were measured to determine the correlation between ankle motion and EMG signals. CNN and ADAM were used for algorithm production, and ankle motion was estimated with high accuracy.
Data analysis and collection techniques now allow for detailed inventory‐building of urban rooftops for the purposes of identifying solar energy potential within geographically defined boundaries, ...including those of cities. The complexity and inherent diversity of a city's building stock has propelled the introduction of many so‐called “solar city” assessment methods that, with varying levels of accuracy, scalability, and ease of use, seek to characterize the citywide solar photovoltaic (PV) resource potential. A review of the landscape of available methods supports a fundamental distinction across two classes of methods. First, “solar city” assessment methods can principally rely on inference to identify and characterize rooftop solar potential. Such inferential methods can establish estimates of citywide solar potential without needing direct insight into rooftop conditions or morphology, Second, measurement‐based methods estimate rooftop solar opportunities based on the direct measurement of rooftop conditions, often conducted through remote sensing. Comparative performance testing of several inferential‐ and measurement‐based methods using case study analysis underscores the importance of measurement‐based methods. In particular, measurement‐based methods are likely better positioned to support the needs of policy‐makers and investors interested in transforming a city or metropolitan area into a sustainable city whose buildings serve as the host of a new solar PV‐powered distributed electricity service system.

As DRAM cells are scaled down, performance and reliability have become critical issues. DRAM reliability issues, including static data retention and tRDL, have proven challenging as interface trap ...density increases through scaling transistor cells. Some ionic charges, such as Chlorine and Hydrogen, are inevitably in-flowed in DRAM cell transistor during Shallow Trench Isolation process (STI), especially in Trench Sidewall Silicon Oxide (Trench-Ox) formation. These ionic charges not only serve as traps but also have negative impact on DRAM structure. In this paper, we propose a novel interface engineering of Trench-Ox layer that improves DRAM performance and reliability by lowering the impurities. In addition, proposed process aims to improve wiggled patterns of STI.
This research analyzed the current situation and problems with an environmental impact assessment to provide a rational ocean physics assessment technique for power plant thermal effluent. This ...research also tried to create an improvement plan for heated effluent diffusion impact assessment by examining the reporting regulations for environmental impact assessment, national and international evaluation guidelines, etc. In the case of evaluating the oceanographic impact of heated effluent discharged from power plants, a pre-investigation is necessary before a full-scale presentence investigation, to accurately predict and minimize power plant construction effects on the surrounding environments. Before this presentence investigation, moreover, an integrated presentence plan, which agrees with the business plan, effect prediction, and post-investigation, needs to be established. A sufficient summit investigation must be made, which considers climate changes, and new and additional power plant construction. For accurate long-term oceanic environmental change prediction, the credibility of effect prediction must be elevated by presenting an evaluation method that is categorized by numerical organization models, verification methods, result presentation, and other things. Furthermore, unproductive conflicts between the people involved in heated effluent evaluation should be reduced by these improvement plans.
This study considered a seagrass habitat in order to analyze the characteristics of a marine environment of seagrass located in the Seomjin river estuary, through an analysis of the distribution of ...the water depth, field observation, and three-dimensional numerical experiments using an EFDC model. The seagrass habitat was usually distributed at D.L(-) 0.5~0.0 m, and was hardly seen in the intertidal zone higher than that range. The distribution of the water temperature was within the range of $7.0{\sim}23.2^{\circ}C$, and the seagrass was demonstrated to have a strong tolerance to changes in the water temperature. In addition, the salinity distribution was found to be 27.2~31.0 psu, with suspended solids of 32.1 mg/L, which were higher than the previous research results (Huh et al., 1998), implying that there may be a reduction in the amount of deposits caused by the suspended solids. As for the sedimentary facies, they were comprised of 62.7% sand, 19.1% silt, and 18.2% clay, indicating that the arenaceous was superior and the sedimentary facies were similar to that of Dadae Bay. According to a numerical experiment, the maximum tidal current was 75 cm/s, while the tidal residual current was 10 cm/s, confirming that it sufficiently adapted to strong tidal currents. The erosion and deposition are predicted to be less than 1.0 cm/year. Thus, it is judged that the resuspension of sediments due to tidal currents and the changes in sedimentary facies are insignificant.
Transformation of the urban energy metabolism is possible when sustainable energy is positioned as an infrastructure‐scale tool. A review of urban energy planning research is complemented by an ...examination of assessment methods in use to gauge the feasibility of planning sustainable energy as a new infrastructure to power cities. A case study analysis of the city of Daejeon is offered to operationalize this planning strategy. In particular, the integrated application of the “savings city” and “solar city” concepts where, respectively, citywide deployment of energy efficiency and rooftop photovoltaic energy systems is envisioned at a large‐scale, is explored for Daejeon through the innovative use of geospatial assessment methods and a visualization tool that can guide urban policy. This assessment and its visualization illustrates not only grid energy use divisions throughout the city but also reveals possible energy planning trajectories in pursuit of positioning sustainable energy as urban infrastructure. The assessment finds that cities like Daejeon could fulfill over half of their electricity service needs through in‐city deployment of sustainable energy at the infrastructure‐scale. Cities that embark on this “sustainable city” trajectory essentially reform the lived experience of “the city” and reshape the city‐energy relationship.

Physical exercise and vitamins such as ascorbic acid (ASC) have been recognized as an effective strategy in neuroprotection and neurorehabilitatioin. However, there is a need to find an efficient ...treatment regimen that includes ASC and low-intensity exercise to diminish the risk of overtraining and nutritional treatment by attenuating oxidative stress. In the present study, we investigated the combined effect of low-intensity physical exercise (EX) and ASC on kainic acid (KA)-induced seizure activity and oxidative stress in mice. The mice were randomly assigned into groups as follows: “KA only” (n = 11), “ASC + KA” (n = 11), “Ex + KA” (n = 11), “ASC + Ex + KA” (n = 11). In the present study, low intensity of swimming training period lasted 8 weeks and consisted of 30-min sessions daily (three times per week) without tail weighting. Although no preventive effect of low-intensity exercise or ASC on KA seizure occurrence was evident, there was a decrease of seizure activity, seizure development (latency to first seizures), and mortality in “ASC + Ex + KA” compared to “ASC + KA”, “Ex + KA”, and “KA only” group. In addition, a preventive synergistic coordination of low-intensity exercise and ASC was evident in glutathione peroxidase and superoxide dismutase activity compared to separate treatment. These results suggest that low-intensity exercise and ASC treatment have preventive effects on seizure activity and development with alternation of oxidative status.
