The purpose of this study was to examine the impact of balance training on the Inbody and recovery of the balance capability in stroke patient with obesity. The exercise program was to conduct obesity group and normal weight group, 22 subjects were divided equally into experimental (obesity) and controlled group (normal weight), assigned to exercise using the balance training system for 30min a day and 5 days a week. Every pre and post-experimental data of both groups were gathered by Inbody and BSS (Biodex Medical Systems) for 8 weeks. As a result, Comparing the intra-group data measured by Inbody, obesity group showed significant difference in every parameter (p<.05). In the inter-group data, every parameter showed significant difference between both groups (p<.05). Comparing the intra-group data of LOS(Limits Of Stability), obesity group showed significant difference with all parameters, except with 'Backward' and 'Left' (p<.05). In the inter-group data, 'Forward' parameter showed significant difference. Comparing the intra-group data of PS (Postural Stability), obesity group showed significant difference with all parameters (p<.05). The inter-group PS (Postural Stability) results differed significantly only with 'Med/lat'(p=.000). In summary, when considering the above results, we concluded that the balance training had a big effect on the Inbody and recovery of the balance capability in stroke patient with obesity.
本研究旨在探讨平衡训练对脑卒中合并肥胖患者体内平衡能力及恢复的影响。运动方案分为肥胖组和正常体重组，22名受试者平均分为实验组(肥胖组)和对照组(正常体重组)，使用平衡训练系统进行运动，每天30分钟，每周5天。两组的实验前后数据均由Inbody和BSS (Biodex Medical Systems)收集，为期8周。因此，与Inbody测量的组内数据相比，肥胖组各参数均有显著差异(p< 0.05)。在组间数据中，两组间各项指标差异均有统计学意义(p< 0.05)。比较LOS(Limits of Stability)组内数据，肥胖组除“Backward”和“Left”外，其余参数均有显著差异(p< 0.05)。在组间数据中，“Forward”参数有显著性差异。比较组内PS(姿势稳定性)数据，肥胖组各参数差异均有统计学意义(p< 0.05)。组间PS(姿态稳定性)结果仅在“Med/ late”组间有显著差异(p= 0.000)。综上所述，综合以上结果，我们认为平衡训练对卒中合并肥胖患者的体内及平衡能力恢复有较大的影响。

In the present study, the surface reactions occurring at the graphite negative electrodes of lithium secondary batteries in propylene carbonate (PC)-based media were examined. The electrode reactions were significantly affected by the electrolyte concentration. In a concentrated solution (3.27 mol kg LiClO4/PC), lithium ions were reversibly intercalated within graphite. In contrast, continual electrolyte decomposition and exfoliation of the graphene layers occurred in a low concentration solution (2.45 mol kg LiClO4/PC). In situ electrochemical atomic force microscopy revealed the formation of an effective surface film on the graphite surface after potential cycling in the 3.27 mol kg LiClO4/PC solution. The results of Raman analysis indicated the absence of free PC molecules in the concentrated solution, which suggested that ion–solvent interactions are an important factor for regulating the formation of stable surface films on graphite negative electrodes in PC-based solutions.
研究了碳酸丙烯(PC)基介质中二次锂电池石墨负极的表面反应。电解质浓度对电极反应有显著影响。在浓溶液(3.27 mol kg LiClO4/PC)中，锂离子可逆嵌入石墨。相反，在低浓度(2.45 mol kg LiClO4/PC)溶液中，石墨烯层发生持续的电解质分解和脱落。原位电化学原子力显微镜显示，在3.27 mol / kg的LiClO4/PC溶液中电位循环后，石墨表面形成了有效的表面膜。拉曼分析结果表明，高浓度溶液中没有游离的PC分子，这表明离子-溶剂相互作用是调节PC基溶液中石墨负极表面膜形成的重要因素。

Abstract Signal transmission characteristics of the barrel-less pogo pins are analyzed using 3-dimensional electromagnetic field simulation. To obtain better signal transmission, the insertion loss and the reflection loss of the pogo pins are calculated with various signal-ground pin assignments. The effects of the signal transmission characteristics of the pogo pins on the increase in the number of the ground pin are investigated. Their characteristic impedances (Z0) are also calculated to analyze the frequency response of the pins.

The transmission process of organizational practices from headquarters to subsidiaries underlies dual institutional pressures from the host country institutional environment and headquarters’ demands. This paper takes the analysis from a macro-institutional level to the level of the individuals involved in the transfer process. The influence of the subsidiary HR manager’s nationality and the resulting degree of overlap between HRM systems in headquarters and subsidiaries is modeled with three variables: reputational effectiveness, allegiance, and ability to speak the headquarters’ language. Based on the theoretical considerations, the subsidiary HR manager’s nationality appears to have an influence on the degree of overlap of the HRM systems in headquarters and subsidiaries.

The present study investigates the use of high-frequency verb collocations in L2 learner English. Although it has been widely accepted that collocations are essential to language use, until recently, the complexity of collocations was mainly hidden. However, developments in the new technology of corpus linguistics and the availability of large electronic texts from spoken and written sources have made possible new perspectives to learner language use. In addition, learner corpus data constitutes a new type of performance data which offers a valuable view of learners’ errors and non-errors as well. This study is thus embedded in a combination of elaborate manual investigation and computer-aided analysis using a concordance program, WordSmith Tools. The results of this study show that errors are not entirely mismatch between the verb and the noun, and other types such as prepositional errors and determiner errors were relatively more frequent among advanced L2 learners. It is also found that the interference of the Korean learners’ L1 plays a role in the use of collocations. Based on the results, some suggestions are made for collocation learning that is helpful for EFL learners.

Core stability exercise is known to have an effect on muscle activation in the shoulder region. Twenty-three healthy adult men and women, aged 19 to 27 years, volunteered to participate in this study. The purpose of this study was to examine the effect on shoulder region muscle activation during the presence or absence of the core stability. Muscle activation was measured by surface EMG and ultrasound imaging during the exercise, and was simultaneously recorded from upper trapezius, low trapezius, and serratus anterior muscles in surface EMG. EMG values were normalized by maximum muscle contractions (%maximum voluntary isometric contraction; [%MVIC]). A paired t-test was used to compare the differences in the muscle activation according to the presence or absence of the core stability. In the results of this study, when subjected to core stability exercise, EMG activation of the upper trapezius muscle decreased by 19%, and the serratus anterior muscle increased by 11%(p .05). These findings suggest that core stability shoulder exercise could be more effective in the shoulder region in patients with chronic shoulder pain.
