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.

The purpose of this study is to examine phonetically if the spelling errors produced by foreign Korean learners are related to learners’ pronunciation by analyzing the pronunciation of plain, tense, and aspiration sounds of foreign Korean learners using a Praat. A statistical analysis was performed on the listening, reading, and writing data produced by 18 foreign university students at the beginner level. The results are summarized as follows. First, foreign Korean learners accounted for the majority of errors in plain and aspiration sound among initial obstruent words. This can be interpreted as an extremely strong or very weak pronunciation of the word, because learners do not properly recognize the intensity of range in plain sounds. Second, the more accurate the learner’s perception was, the more accurate production can be made. Statistically, it was found that the production rate increased by 0.178 each time the perception rate increased by 1. Therefore, the correlation between perception and production is established. Third, the relationship between pronunciation and spelling is a relationship that increases by 0.652 each time the pronunciation increases by 1. It can be explained that there is a possibility that the learner may often write words as they pronounce them.

Because the damages of corrosion resulting from the chloride ion are very serious, many research studies have been performed to measure the penetration depth of the chloride ion. However, there is a problem with data selection obtained from collection during experiments. In this study, it appears that the collected data are not conformed to a normal distribution. The result of this study will play a very important role, as a first step for the development and construction of a forecasting system to help determine a reliable service lifetime of marine structures.

본고의 목적은 일본인 학습자에게 효율적인 한국어 연결어미 ‘-아/어서’와 ‘-고’에 대한 학습방안을 모색하는 데 있다. 먼저 한국어 연결어미 ‘-아/어서’와 ‘-고’에 대응하는 일본어 접속조사 ‘-て’의 의미 용법을 한일 대조의 입장에서 살펴보았다. 일본어의 ‘-て’의 용법을 분석한 결과, 순서, 나열, 수단․방법, 원인․이유, 역접 등 거의 모든 연결 관계에 걸쳐서 나타났다. 이에 오류의 원인을 과잉일반화와 모국어의 간섭에 주안점을 두고 학습자의 오류양상을 형태상의 시제오류와 의미상의 대치오류로 분류하였다. 시제오류에서는 ‘-ので’의 간섭으로 보고 반복적 활용연습에 초점을 두고 학습방안을 제시하였다. 대치오류에서는 ‘-て’의 과잉일반화로 ‘-아/어서’와 ‘-고’에 대치되는것으로 보고 초급에서 중점으로 다루는 순차성과 수단 방법의 용법으로 범위를 제한하여 교수 학습방안을 제시하였다.
