기계학습 방법에 기반한 자연어 분석은 학습 데이터가 필요하다. 학습 데이터가 구축된 소스 도메인이 아닌 다른 도메인에 적용할 경우 한국어 의미역 인식 기술은 10% 정도 성능 하락이 발생한다. 본 논문은 기존 도메인 적응 기술을 이용하여 도메인이 다르고, 문장의 형태도 다를 경우에 도메인 적응 알고리즘을 적용하여, 질의응답 시스템에서 필요한 질문 문장 의미역 인식을 위해, 소규모의 질문 문장에 대한 학습 데이터 구축만으로도 한국어 질문 문장에 대해 성능을 향상시키기 위한 방법을 제안한다. 한국어 의미역 인식 기술에 prior 모델을 제안한다. 제안하는 방법은 실험결과 소스 도메인 데이터만 사용한 실험보다 9.42, 소스와 타겟 도메인 데이터를 단순 합하여 학습한 경우보다 2.64의 성능향상을 보였다.

In a sense that achievement emotion is directly associated with achievement activity of students and its result, drastic changes in educational environment such as expansion of e-learning due to COVID-19 may have a large impact on the achievement emotion of students inevitably. However, studies on the foregoing still remain insufficient, and development of a questionnaire capable of making a quantitative measurement on the achievement emotion of students under the environment of e-learning may become the basis of relevant studies, so this study developed the e-learning Achievement Emotions Questionnaire-Korean Middle school Science(e-AEQ-KMS) and verified its validity. e-AEQ-KMS in this study was developed based on the Achievement Emotions Questionnaire-Korean Middle school Science (AEQ-KMS) and by reflecting characteristics of e-learning science class. With 226 questions in total, the questionnaire is composed to measure 9 kinds of achievement emotion such as enjoyment, hope, pride, relief, anger, anxiety, hopelessness, shame, and boredom under 3 academic situations of class situation, learning situation and testing situation. The result of this study has a great significance in the way that it set out a framework for making a comparative analysis quantitatively on the achievement emotion of Korean middle school students in science for e-learning classes.

The moderners of industrial society suffer from various stresses, which bring about increase in prevalence of temporomandibular disorders, oral mucosal disease and chronic neuropathic pain, therefore, the number of patients seeking help of those symptoms tend to increase. The purpose of this study was to discuss the importance of oral medicine related disease by investigating questions that appeared in cyber consultation of Kangnung National University Dental Hospital web site. Among the nearly 2000 questions, the rate of questions related to oral medicine was 20.92%, and the rate of questions related to other departments were oral and maxillofacial surgery 16.87%, conservative dentistry 16.67%, orthodontics 14.02%, prosthodontics 12.25%, periodontics 8.36%, pediatric dentistry 4.93%, preventive dentistry 2.08% and otherwise questions 3.90%. Among the 403 questions related to oral medicine, the frequent questions were oral mucosal diseases 44.17%, temporomandibular disorders 41.19%, halitosis 4.47%, xerostomia 3.23%, other orofacial pain 2.23%, forensic dentistry 1.49% and otherwise questions 2.98%. From the higher rate of questions related to oral medicine compared with other fields of dentistry, we would consider that the people are considerably concerned about the oral medicine related disease, such as oral mucosal diseases and temporomandibular disorders.

This paper is intended to valuate air quality of the Seoul Metropolitan Area using triple-bound dichotomous choice (TBDC) contingent valuation method (CVM), supplemented by open-ended (OE) questionnaires. In the OE questionnaires, some respondents would state their willingness to pay (WTP) outside the limits of the WTP interval. It implies that WTP estimates based on the customary dichotomous choice (DC) questionnaires can be biased. We argue that the TBDC-CVM refined with OE questions is more efficient, because the latter helps purge the former of corrupted data that may have been collected by the TBDC interview process.

The purpose of this study was to understand characteristics of eighth graders' conclusions presented in their self-directed scientific inquiry reports. We developed a framework, Analysis of Conclusions of Self-Directed Scientific Inquiry, to analyze students' conclusions. We then compared the conclusions with the inquiry questions students generated to find out whether the questions affected students' conclusions. In addition, we analyzed students' responses from the survey about their perceptions of drawing conclusions. According to the results, the conclusions were characterized into two categories, i.e., scientific basic assumption and scientific explanation. Almost half of the students' conclusions fall under the scientific basic assumptions. Most of the scientific explanations were deductive explanations and inductive explanations. Then, the kinds of conclusions were affected by the inquiry questions because the scientific explanations were made more than the scientific basic assumptions in answering the inquiry questions. Some students couldn't recognize differences between conclusions and experiment results.

The most common method in the psychological measuring method for measuring user's emotions is to indirectly measure the user's emotion by using adjectives, called emotional words. The previous research, in order to observe user's emotional changes while they interact with a product, has extracted some emotional words and representative emotions, and made a set of subjective evaluation scale. In addition to adjective checklists, self-report questionnaire-type scales have been extensively used to assess user's emotions. This research suggested a self-report questionnaire-type scale using the representative emotions and a set of subjective evaluation scale made in the previous research. Also the reliability of the suggested self-report questionnaire-type scale was confirmed through the analysis of Cronbach's coefficient alpha. Therefore, the self-report questionnaire-type scale extracted through this research can be used in various ways to measure a user's user's emotions naturally expressed while using a product.

The purpose of this study was to investigate the directives and Wh-words in the directives from elementary 2nd, 4th and 6th grade Korean textbooks. After entering all directives into Microsoft Office Excel, directives with Wh-words were separated. The analysis program, Natmal, was used for the analysis of the directives and Wh-words. The criteria from previous studies were also applied for this analysis process. As a result of the study, there are a lot of nouns and verbs in directives. They were consisted of sentences with an average of 6.9 Eojeol. There were a total of 11 types of Wh-words and 'Mueot(what), Eotteon(which), eotteohge(how)' appeared most frequently in all grades. For question types, both grades had more inferential questions than literal information questions. This results were expected to be used as basic data for language interventions with school aged children who have language disorders.
