PURPOse： This study examined whether the use of trekking poles alters metabolic cost in steep hiking by novice hikers and whether the response would be dependent on the grade of the terrain. METHODS： Twelve participants completed two trekking trials （with poles [WP] and without trekking poles [NP]） with round trips comprising three grades： 7.0 ± 0.7°, 12.9 ± 0.7°, and 18.8 ± 1.3°） over a steep mountain at self-paced speeds. During the trials, time spent for trekking （TT）, oxygen consumption （VO2）, heart rate （HR）, ratings of perceived exertion （RPE）, and step frequency （Sf） were measured, and step efficiency （se） and oxygen pulse （OP） were calculated. RESULTS： TT tended to be longer in the WP than NP for both terrains （P 〈 0.05）. HR, VO2, and RPE were the same for the WP and NP. Sfwas lower in WP going uphill （P 〈 0.05） but was unchanged going downhill. se in the WP was higher than in the NP for both terrains （P 〈 0.01）. When analyzed by slope, VO2 during uphill at 18.8° was lower in WP （37.2 ± 6.3） than in NP （38.6 ± 7.1 ml .kg-1 .min-1, P 〈 0.05）, but no difference in VO2 was found between WP and NP at the 12.9° and 7.0°. TT during uphill was slower in WP than NP at 12.9°（7.9± 1.1 vs. 7.4 ± 1.0） and 18.8° （5.3 ± 1.3 vs. 4.9± 1.0 min, respectively, P 〈 0.05）. No differences were noticed in HR and OP during uphill at every grade. CONCLUSIONS： Pole use decreased metabolic cost in the novice hikers only in the highest grade but not in the other two lower grades.

本文实证探讨了韩国语境下对行政能力概念的理解和变化。尽管各方对其重要性已达成普遍共识,但政治权威和利益相关者(在本研究中为:公众、国民议会成员和学术界)对行政能力的定义并不相同。为了增强对行政能力的理解,我们收集了三种类型的文本(2000年至2019年的337篇学术论文、1470篇国民议会会议记录和3316篇报纸文章),并使用主题建模和文本网络分析方法对数据进行了分析。结果表明,尽管学术论文强调领导力、人力、教育等决策能力,但是国民议会强调解决不同政策问题的创新能力,而被认为反映公共舆论的媒体则强调与国家安全相关的能力。
