Previous studies on English spelling have investigated the types of spelling errors and their frequencies, and studies on why learners made those errors have been called for. This study aimed to identify factors leading to errors in the English-spelling of Korean elementary school students. The factors were investigated by using the following methods: A total of 130 students from O Elementary School were given three types of word-writing tasks: dictation of single words, dictation of short sentences, and writing words as many as the students can based on pictures depicting familiar scenes. The errors in their writing samples were classified into five types. The students were interviewed about why they made those errors. The results showed that the errors were influenced by the factors: the students’ first language, background knowledge, pronunciation, and morphological reasons. The results suggest that if teachers understood these factors, they would be able to explore better teaching methods for reducing errors in English spelling, and that future research could apply these factors for further investigations.

“Haishi” has many meaning. We still feel unclear about usage of “Haishi” in the teaching practice. The article makes a study of the basic meaning and the derival meaning of the “Haishi”. Some of which have the counter-expectation or the expectation pragmatic functions in a given context. But the basic meaning lingers in the “Haishi” ,which gives rise to its pragmatic functions. Through this analysis, we can be more clear about the true meaning of this adverb. So this paper not only reveals some pragmatic functions of the “Haishi”, but also clarifies the inherent relation of those meanings.

Loxoprofen-Na (sodium 2-[4-(2-oxocyclopentylmethyl)phenyl]propionate dihydrate) is a potent analgesic drug. We developed loxoprofen-Na plasters to extend duration time of analgesic activity and to reduce side effect on gastrointestinal tract. Analgesic effect of Loxoprofen-Na plasters was investigated. Loxoprofen-Na plaster had good analgesic effect in rat paw pressure test, Tail-flick latency test and acetic acid-induced writhing test. Also, it had anti-inflammatory effect on carrageenan-induced rat hind paw edema. In pharmacokinetic study of Loxoprofen-Na, plasters dosage form showed that plasma drug concentration was prolonged up to 14 hours. So, we can conclude that loxoprofen-Na plasters, when applied on skin, will he a new type of drug for controlling the various local pain or inflammation.
