This study is about the ungramamtical use of 〈ttaemune (때문에)〉. Because 〈ttaemun (때 문)〉 is a bound noun, a noun modifier is essential before it. So 〈ttaemune〉 also needs a modifier before it. But on the actual language usage, 〈ttaemune〉 is often used without modifiers. This phenomenon appears to be mainly limited to cases where 〈ttaemune〉 is used between sentences. That is, in this case, 〈ttaemune〉 is used as the conjunction like 〈geulaeseo (그래서)〉. Previous research has treated this ungrammatical aspect of 〈ttaemune〉 as a representative example of the degrammaticalization phenomenon. In other words, it has been understood that because the bound noun 〈ttaemun〉 has gained independency, 〈ttaemune〉 is used without modifiers before it. However, it is difficult to accept degrammaticalization discussions positively in the following respects: this phenomenon is not so common as to be recognized as a particular grammatical phenomenon, and if this is due to the independence of 〈ttaemun〉, this should also occur in other cases where 〈ttaemun〉 is combined, but this is not the case. So, I think it is right to treat them as objects that need to be corrected rather than treated within language norms.

In most of the medical literature that discusses the common problem of movement in patients with cerebral lesions. This critical problem is ascribed to a mechanism involving uninhibited neural activity. The goals of neurological physical therapy are focus on reduce of muscle hypertonicity, facilitates muscle activities, and improve of performance in living environment. A variety of studies suggest that spasticity is a distinct problem and separate from the muscle weakness. It has become increasingly recognized that the major functional deficits following brain damage are largely due to negative features such as muscle weakness and loss of performance rather than spasticity. Adequate recruitment of prime mover, not release was able to carry out the movement tasks well. The strengthening exercise of spastic limbs on changes in muscle properties and performance skill, the repeated motor practice has been identified as crucial for motor recovery. This article support the concept that strengthening is an appropriate intervention to improve the quality of physical function in patients with central nervous system lesions. Further studies and therapeutic approaches should be efforts at improving motor neuron recruitment in agonist rather than reducing activity in antagonists while retraining muscle strengthening.
