Objective: Electrical stimulation is an assistive technology used to aid the recovery of upper limb use after stroke. The purpose of this systematic review was to determine the effects of electrical stimulation on upper extremity function in individuals with hemiparetic stroke and to develop an evidence base that supports the use of electrical stimulation for upper limb recovery after stroke. Design: A systematic review based on randomized controlled trials (RCTs). Methods: Studies published before April 20 2021 were collected for this review by searching PubMed, four other databases, and RCTs that reported the effects of electrical stimulation on upper extremity function in individuals with the characteristic stroke type. Information on the following parameters was extracted from each study: surname of first author, published year, country, participants, intervention, intervention's intensity, comparison, outcomes, additional therapy, and summary of results. This review also evaluated the bias within each study, including any selection bias, performance bias, detection bias, attrition bias, and reporting bias. Results: This review included five RCTs, and 208 stroke patients were included in the analysis. Stroke patients who underwent electrical stimulation showed significantly improved grip and pinch strengths, wrist range of motion, and basic daily living compared to those in the control group; however, there was no improvement in upper extremity function. Of the selected papers, 60% showed a "high risk" of performance bias, and 20% showed a "high risk" of detection bias. Conclusions: The results of this systematic review suggest that electrical stimulation provides some benefits to stroke patients, such as improved hand strength and range of motion. However, future studies are needed to provide clinical evidence of the effects of electrical stimulation on upper extremity function in stroke patients.

풍력자원 평가와 예측의 정확도를 향상시키기 위해서는 연직바람관측자료를 수치모형에 반영해야 한다. 기상청에서는 레윈존데(rawinsonde)와 연직바람관측장비(wind profiler radar)를 활용하여 고층기상을 관측한다. 레윈존데의 경우 시간해상도가 일 2회로 매우 낮은 반면에 연직바람관측장비는 10분 주기로 자료를 제공하므로 풍력자원 평가 및 예측에 보다 적합하다. 따라서 본 연구에서는 풍력자원 평가 및 예측 모델 개발을 위한 선행연구로 기상자료개방포털에서 제공하는 연직바람관측자료를 분석하여 우리나라의 풍황 특성을 분석하였다. 이를 위해 기상자료개방포털에서 제공하는 모든 연직바람관측자료를 수집하였으며, 이를 지역별, 월별로 분석하여 연직바람관측장비의 관측 특성을 검토하고 지역 및 계절별 풍황 특성을 분석하였다.
