A new six-rowed naked waxy barley variety, ‘Saehanchal’, was developed by the barley breeding team of the National Institute of Crop Science (NICS), R.D.A. This variety was derived from a cross between ‘SB7803G-BC6-B-B-47-2’ and ‘Suwon262’ in 1989. The fi

Skill used in the broadest context of physical education and sports was defined in various terms and its meanings were illustrated from several different theoretical perspectives, i.e., from physiological, psychological, biomechanical, and behavioral points of view. The viability of diversified theoretical approaches was discussed in terms of levels of analysis, parameters of analysis, and units of analysis. In view of current theoretical developments, two different kinds of currently prevailing approaches to the production and control of movement (and thus, skill) were contrasted and examplified in terms of explainability of movement phenomena. Theoretical as well as practical implications of motor control researches were discussed in relation to surrounding disciplines with suggestions of direction in future researches.
