Given a query (a health question), retrieval of relevant frequently asked questions (FAQs) is essential as the FAQs provide both reliable and readable information to healthcare consumers. The retrieval requires the estimation of the semantic similarity between the query and each FAQ. The similarity estimation is challenging as semantic structures of Chinese healthcare FAQs are quite different from those of the FAQs in other domains. In this paper, we propose a conceptual model for Chinese healthcare FAQs, and based on the conceptual model, present a technique ECA that estimates conceptual similarities between FAQs. Empirical evaluation shows that ECA can help various kinds of retrievers to rank relevant FAQs significantly higher. We also make ECA online to provide services for FAQ retrievers.

What is radical constructivism There were many questions arose related with radical constructivism in mathematics education. In this paper, the author put seven frequentlyasked questions on radical constructivism and described each question one by one in light with constructivists' point of views. The questions included types of constructivista, radical constructivism, trivial or weak constructivism, and social constructivism; representative people in radical constructivism; matter of ontological reality; evaluation of others' work; shared meaning; social influence; and teacher's roles from the perspectives of radical constructivism. The author added his opinions ell each Question.

The purpose of this study was to examine the questions in the 'Matter' units of elementary science textbooks under the 7th curriculum. For the analysis, a total of 338 questions were extracted from 15 units. Six criteria (recalling, recognizing, predictive, applied, divergent, and evaluative question) were reconstructed for textbook question analysis based on Blosser(1973)'s question category system for science. The results were as follows. First, there were more closed (recalling, recognizing, predictive, or applied) questions (72.2%) than open (divergent or evaluative) questions (27.8%) in elementary science textbooks. Second, cognitive-memory (recalling or recognizing) question type was the most frequently asked in all grade levels. Open (divergent or evaluative) questions increased according to grade level whereas convergent (predictive or applied) questions decreased. Third, question types were applied based on the characteristics of each unit rather than on children's developmental characteristics. Educational implications were discussed based on the results.

소집단 실험활동에서 학생간 질문의 유형과 빈도를 파악하기 위하여, 서울소재 여자중학교 1학년 학생 5명의 실험수업을 관찰하고 관찰학생을 면담하였다. 소집단 실험활동에서 학생간 질문을 분석한 결과, 사고형 질문보다 정보형 질문의 빈도가 높았다. 정보형 질문의 대부분은 실험과정이나 결과를 묻는 절차질문이었다. 사고형 질문의 대부분은 결과를 해석하면서 잘 이해되지 않은 부분에 대하여 설명을 요구하는 이해질문이었다. 드물게 변칙발견질문이 제기되었으나 학습을 위한 토론으로 이어지지 않았다. 그리고 2인1조로 활동을 한 경우에 5인1조의 경우보다 응답률이 높았고, 도움을 받는 질문의 비율도 높았다. 2인1조 활동에서는 성취도가 상대적으로 낮은 학생이 질문하고 성취도가 높은 학생이 응답하는 경향이 두드러졌다. 또 구성원의 성취도 차이가 큰 조에서는 질문의 빈도가 낮게 나타났으며, 구성원의 성취도 차이가 적은 조에서는 성취도에 따라 질문 유형의 차이가 나타났다. 결론적으로 소집단 실험활동에서 제기되는 학생간 질문은 사고형 질문보다 정보형 질문의 빈도가 높으며, 구성원의 수가 적을 때 응답을 통해 도움 받는 질문의 비율이 높았다.

The focus of this dissertation is on the comparative Analysis of Questions in the 'Matter Units of Elementary Science Textbook between the 7th Curriculum and the Revised Curriculum Year 2007. The results of the comparative Analysis in the dissertation are as follows: There were more closed questions than open questions in these elementary science textbooks both of the 7th Curriculum and the Revised Curriculum Year 2007. Cognitive-memory questions were the most frequently asked in all grade levels. In the Revised Curriculum Year 2007, Convergent thinking questions presented with higher rate than the 7th Curriculum. Divergent thinking questions and evaluative thinking questions was presented with a relatively lower rate than the 7th Curriculum. Question types were applied based on the characteristics of each unit rather than on children's developmental characteristics.

본 논문에서는 한국천문연구원에서 2000년부터 운영중인 홈페이지 질문상자의 질문 및 조회 수를 통계적으로 분석하고, 그 질문 내용에 나타난 인지적 측면에서 과학탐구 유형을 분석하였다. 이를 위해 홈페이지 질문상자에 올라온 질문 및 조회 수를 월별/연도별로 통계를 작성하였으며, 질문문항이 과학탐구의 어떠한 인지적 측면이 부각되어 있는가를 분석하기 위하여 과학탐구 분석틀을 개발하였다. 질문유형 분석은 인지적 측면에서 과학지식과 과학탐구로 분류하였다. 과학적 지식의 하위유형으로 내용지식, 방법지식, 지식본성 이해로 분류하였다. 과학탐구의 하위 요소는 과학탐구 수행능력으로 분류하고 각 세부 요소를 고려하였다. 질문유형 분석틀에 따른 과학탐구 유형의 분석은 분석틀을 통해, 2004년 7월부터 12월까지 6개월간 질문상자에 질문한 703개 질문 항목에 대해 질문들의 세부 사항 및 속성들을 세부적으로 살펴서 질문유형 분석틀에 따라 분석을 시행하였다. 이 분석을 통하여 질문상자의 질문에 대한 이해와 잦은 질문들에 대한 응답을 마련하는 등, 앞으로 질문상자의 운영 방안에 대한 방향을 설정할 수 있었다. 이 분석을 통해 질문수의 증가와 함께, 질문의 내용도 일상생활 과학 지식수준을 넘어 해마다 난해해 지고 전문화 되어가고 있음을 알 수 있었다. 앞으로 질문상자의 이용자 수가 계속 증가될 것으로 예상되고, 지적 요구의 증대와 함께, 질문의 내용도 더욱 난해해 질 것으로 예상됨으로 심도 있는 콘텐츠의 개발이 필요하다.

The purpose of this study is to analyze the contents of the questionnaires used in dietary surveys and to evaluate each item in relation to the item construction strategy. Articles of which the contents were related to food, nutrition, diet, dietary behavior, and related areas. Published from 1997 to 1999 were searched fir and a total of 121 questionnaires were collected and analyzed. The questions in the questionnaires were classified into related areas and sub-areas. Among the keywords in the title of the articles, the term 'nutritional status'(or 'dietary intake status') was most frequently used. The terms such as dietary status, obesity, health, food habit, and dietary behavior were also frequency used. Major topics of the items in the questionnaires varied according to the life cycle of the subjects of the study. The topics most frequently asked in each lift cycle were as follows : overeating, snack, and food preference for preschool- and school-aged children ; anthropometry, weight control, and snack for middle and highschool students : meal skipping, smoking, and drinking for college students : disease, smoking, drinking, and exercise for adults : and smoking, drinking, disease and perceived health for the elderly. Inappropriate questions with complicated language, typographic and grammatic errors, unnecessary words, and negative questions were found. Therefore, care should be taken to construct each question so as to avoid possible misinterpretation. Also, a standardized questionnaire be developed for survey researchers.

With the advent of multidetector-row CT, lung cancer imaging is much more promising than before. However, the effectiveness of multidetector-row CT in making an initial diagnosis, staging, and evaluating post-treatment changes of lung cancer still remains to be proved. Fast imaging along with volumetric data set and attendant multi-planar imaging provide much more details on the anatomic changes and pathology associated with lung cancer. However, with images showing anatomic and pathologic changes only, radiologists confront with several questions the answers of which may help evaluate lung cancer more thoroughly. The frequent questions that I have in dally practice of chest CT interpretation are as follows.

Objectives : This study aimed to investigate the current situation of Internet health counseling in Korean Medicine by analyzing the contents and pattern of the questions and answers in NAVER Jisik-iN. Methods : 1,121 questions answered by Korean Medicine doctors in NAVER Jisik-iN from January 2012 to June 2012 were extracted and analyzed. The contents and pattern of the questions and answers were classified. Then statistical analysis was performed and the research findings were compared with other studies. Results : Korean Medicine (KM) accounted for 1.73 percent of health counseling in NAVER Jisik-iN. Analyzing the questions and answers of KM counseling, questions about symptoms and answers providing medical knowledge were most common. The most frequently asked symptom was digestive disorder. Applying to Suchman's "Stage of Illness and Medical Care" model, 'the symptom-experience' stage took the first place. Conclusions : KM counseling in NAVER Jisik-iN has served as guidance for potential Korean Medicine consumers by providing medical knowledge about symptoms. For more effective guidance there should be a systematic Internet counseling system offering reliable information by KM doctors to meet the needs of medical consumers.
