This article examines the current views and pedagogical approaches of Korean school grammar from the perspectives of usage-based theory, and suggests future directions for Korean Grammar Pedagogy that reflect authentic usage of Korean and facilitate meaningful learning. To this end, the basic assumptions of the usage-based theory were reviewed and its applicability to Korean explored. As a result, it is shown that usage-based theory provides us with alternative explanations that overcome the limitations of traditional school grammar and enable meaningful inquiry activities. At the phonological level, while school grammar has ignored the various CVCC syllable configurations actually observed, from the point of view of usage-based theory, syllable-final consonant clusters such as [rp], [rt], and [rk] are appropriately described. At the morphological level, construction-based morphology sheds light on various schema and patterns of word formation that school grammars have overlooked. Finally, usage-based theory provides an alternative explanation of the complement category defined by school grammar.

PURPOSES : The objective of this study is to identify the characteristics affecting traffic accidents that have occurred in 564 industrial complexes nationwide from 2011 to 2015.METHODS : The traffic accidents were specified using various factors such as industrial complex type (national VS. general), industrial complex degradation (old VS. non-old), location of complex (capital VS. non-capital), and traffic law violation (speeding, signal violation, and median invasion). The average number of crashes and accident ratio (fatal, severe, and both) in terms of characteristics of industrial complexes were calculated. With a sample of crashes of the industrial complexes for 5 years, statistical significances were tested to analyze and compare the differences based on industrial complex and traffic law characteristics using parametric and non-parametric methods.RESULTS: From statistical results, it is observed that the crash frequency occurring in old industrial complexes is three times higher than that in non-old industrial complexes. Old industrial complexes located in a capital area, old national industrial complexes, and old general industrial complexes are considerably related to higher crash frequency, but the fatal accident ratio appeared to have no statistical difference across industrial complex characteristics. Severe crashes are more likely to occur in non-old industrial complexes on an average.CONCLUSIONS : It is necessary to eliminate potential threats to roads and traffic in the same manner as illegal parking in industrial complexes through the restoration of old industrial complexes. To improve the efficiency of road infrastructure, efforts should be made to improve traffic safety in accordance with industrial characteristics such as planning and operation of relevant local government programs.

돈육의 적육을 70%로 하여 등지방을 첨가하지 않고 저지방 프레스햄(A)을 제조하고, 또 돈육과 등지방 배합비를 각각 60%와 10%(B), 55%와 15%(C) 및 50%와 20%(D)로 하여 모두 4종류의 프레스햄을 제조하였다. 이 때에 적육과 등지방 이외의 모든 재료와 제조 조건은 동일하게 하였다. 제조된 프레스햄의 일반성분, 보수력 및 기호성을 비교하고, 이것을 4℃에서 60일간 냉장하면서 10일 간격으로 조직특성의 변화 정도를 비교하였다. 저지방 프레스햄(A)은 수분 71.3%, 조단백질 함량 23.4%로 다른 제품보다 높았으며, 저지방 함량은 2.8%로 현저히 낮았다(p<0.05). 저지방 프레스햄의 보수력은 74.5%로 다른 제품보다 높았다. 저지방 프레스햄의 표면색도 중 명도(L)는 61.6 황색도(b)는 5.9로 다른 제품보다 높게 나타났다. 저지방 프레스햄은 경도가 70, .2, 탄성 85%, 씹힘성 0.49㎏, 뭉침성 2.0% 및 파쇄성이 0.7㎏으로 다른 제품보다 높은 편이었고 응집성의 경우 D제품보다 낮은 값을 보였다. 저지방 프레스햄의 향과 조직감은 다른 제품보다 열등하였으나 맛이 우수하였으며 기호성도 좋은 편이었다.
