Healthcare professionals have edited many health questions (HQs) and their answers for healthcare consumers on the Internet. The HQs provide both readable and reliable health information, and hence retrieval of those HQs that are relevant to a given question is essential for health education and promotion through the Internet. However, retrieval of relevant HQs needs to be based on the recognition of the intention of each HQ, which is difficult to be done by predefining syntactic and semantic rules. We thus model the intention recognition problem as a text classification problem, and develop two techniques to improve a learning-based text classifier for the problem. The two techniques improve the classifier by location-based and area-based feature weightings, respectively. Experimental results show that, the two techniques can work together to significantly improve a Support Vector Machine classifier in both the recognition of HQ intentions and the retrieval of relevant HQs.

One of the learning difficulties for Korean learners of English is the intonation of English focused yes/no questions. Focused words in English yes/no questions are realized as low pitch accents which contrast with high pitch accents in Korean counterparts. In order to improve Korean students' intonation, direct and metalinguistic explanations on the intonation of English focused yes/no questions were given to Korean learners of English. In pre-tests and post-tests, students' perceptions on the target items were measured. The study results showed that phonetic explanation using intonation contour enhanced students' perception on English intonation. With respect to the position of focused words, sentence initial and medial focused questions were more difficult than sentence final focused questions. The perception was most improved in sentence initial focused questions. The study showed the immediate effects of the explicit instruction on perceptions of English intonation.

The purpose of this study is to analyze the trend line through scatter diagram analysis on correlation between SNS addiction tendencies and learning attitudes, figure out the knee point influencing learning attitudes negatively in detail, and examine influence among subareas. To address the goal, study questions are formulated as follows. First, this author did screening on the data of variables measured and analyzed descriptive statistics. Second, this researcher produced the trend line by drawing a scatter diagram in order to analyze correlation between SNS addiction tendencies, withdrawal symptoms, excessive communication, and excessive time wasting, and learning attitudes exploratorily. Third, to explore correlation between self-evaluation, learning participation, and developmental attitudes, the subfactors of learning attitudes related to SNS addiction tendencies, this author drew a scatter diagram and analyzed the threshold of positive and negative correlation. To verify the study questions, the SNS addiction tendency scale and learning attitude scale were applied to 301 university students in Chungcheong area. According to the study results, first, their learning attitudes are influenced by SNS addiction tendencies, excessive communication and excessive time wasting, and they are not influenced by withdrawal symptoms that much. Second, excessive communication, a factor of SNS addiction tendencies, and self-evaluation and developmental attitudes, factors of learning attitudes, show positive correlation to some extent and indicate negative correlation after the threshold. However, excessive communication and learning participation are found to show no correlation. Third, according to the results of examining correlation with learning attitudes by dividing them into excessive communication and excessive time wasting groups with the knee point of 1.40, as the symptom of excessive communication is found more, it influences self-evaluation, learning participation, developmental attitudes, and learning attitudes more negatively in general. The result of this study is expected to provide foundational material necessary to develop educational programs to prevent undergraduates' excessive SNS use and SNS addiction which can be used in the scenes of counseling or education.

현재 국내 국·공립 중등교사가 되기 위한 유일한 등용문은 중등교원 임용시험이며 2014학년도 개정 이후 임용시험의 모든 문항이 서답형으로 전환되었기 때문에 더 완성도 높고 정확하고 견고한 답안 작성이 요구된다. 재인기억을 측정하는 선택형 문항과 비교하면 회상기억을 측정하는 서답형 문항의 경우 정보 인출을 위해 더 많은 인지적 노력이 요구된다. 이 때문에 지속적인 암기 및 인출 연습이 필요하지만 이를 수행할 수 있는 학습 도구가 충분하지 않다. 이러한 맥락에서 본고는 중등영어교사 임용시험 준비용 모바일 어플인 ONE PASS를 구현하였다. 본 어플에서는 특히 인지작용의 근간이 되는 뇌의 작용기제를 반영하여 학습용 콘텐츠를 구현하였으며 학습계획 설정 및 동기측정, 마인드맵, 브레인스토밍, 기출문제 등 다양한 기능을 구안하였다. 본 연구는 학습용 어플 콘텐츠 개발 관련 연구에 이바지함과 동시에 임용시험 수험자들에게 조금이나마 도움이 될 수 있기를 기대한다.
