When confronted with a query, question answering systems endeavor to extract the most exact answers possible by determining the answer type that fits with the key terms used in the query. However, the efficacy of such systems is limited by the fact that the terms used in a query may be in a syntactic form different to that of the same words in a document. In this paper, we present an efficient semantic query expansion methodology based on query patterns in a question category concept list comprised of terms that are semantically close to terms used in a query. The proposed system first constructs a concept list for each question type and then builds the concept list for each question category using a learning algorithm. The results of the present experiments suggest the promise of the proposed method.

This study aimed to investigate and compare the perception of personal protective equipments and instrument sterilization of students who are in attendance at colleges and universities and which have bedside training as a regular subject in their curriculum for third-year students. 'Completely True' is the highest response to the question about the importance of wearing gloves, mask and medical gown from all groups. 'Completely True' is the highest response to the question about the necessity for replacement of gloves from all groups. 'Moderate True' is the highest response to the question about the necessity for replacement of mask from the group without practical training and 'Completely True' is the highest response to the question about the importance of hair cleanliness from all groups regardless of practical training experience. For the question about the perception of instrument disinfection and sterilization, the group with inside and outside practical training showed the highest perception level. Consequently, the right education for prevention of infection by setting inclusive guidelines to enhance the level of perception and practice seems continuously necessary.

Mathematical process is an issue in current mathematics education. In this paper discuss how to assess the mathematical process using essay type questions. For this we first suggest the concept of Mathematical Process Oriented Question which is an essay type question and possible to assess mathematical processes, that is, the mathematical communication, reasoning, and problem solving as well as mathematics knowledge. And we develop a framework for developing the mathematical process oriented question and rubric, examples of assessment standards and those questions containing rubric for assessing mathematical processes. The results of this paper can serve as basic data and examples for follow up research about mathematical process assessment.

In this research, we proposed a learner tailoring question recommendation system for web based learning evaluation system. For teaming evaluation process, this system used the item difficulty Each question was stored and managed to the question bank. Item difficulty was recalculated during teaming process and feedback in next course. For learner tailoring question recommendation, learner could choice the teaming part and set the learning difficulty. In application result of proposal method, almost learner could improve learning score by controling teaming difficulty.

Conversation modeling is an important and challenging task in the field of natural language processing because it is a key component promoting the development of automated humanmachine conversation. Most recent research concerning conversation modeling focuses only on the current utterance (considered as the current question) to generate a response, and thus fails to capture the conversation's logic from its beginning. Some studies concatenate the current question with previous conversation sentences and use it as input for response generation. Another approach is to use an encoder to store all previous utterances. Each time a new question is encountered, the encoder is updated and used to generate the response. Our approach in this paper differs from previous studies in that we explicitly separate the encoding of the question from the encoding of its context. This results in different encoding models for the question and the context, capturing the specificity of each. In this way, we have access to the entire context when generating the response. To this end, we propose a deep neural network-based model, called the Context Model, to encode previous utterances' information and combine it with the current question. This approach satisfies the need for context information while keeping the different roles of the current question and its context separate while generating a response. We investigate two approaches for representing the context: Long short-term memory and Convolutional neural network. Experiments show that our Context Model outperforms a baseline model on both ConvAI2 Dataset and a collected dataset of conversational English.

Gradually, there has been increase in the use of qualitative research methods in nursing research. Nursing scholars are using qualitative research methods to explore the essence of nursing and discover its meaning. However, there has been lack of standards for evaluating qualitative nursing research. Often nursing researchers are applying quantitative research evaluation standards to qualitative nursing research. Thus, there has not been any notable qualitative research done to date. In order to improve the quality of nursing research done to discover new knowledge for the nursing, ＆ for development of nursing theory, criteria for critiquing qualitative research should be established. Therefore, this researcher introduced standards as criteria for critiquing qualitative research which are based on literature reviews and re search experiences. The suggested criteria are developed several question's as follows : 1) description of the research phenomena, 2) significance, 3) research purpose, 4) research question, 5) assumptions, 6) researcher's abilities, 7) selection of research samples, 8) data collection, 9) human subjects, 10) data analysis, 11) description of researcher's results, 12) literature review. Follow-up of concrete questions for each of the criterias have been developed.

The purpose of the current study is to analyze a model of OPIc-based speaking test for Korea English classroom. The research questions were (1). What is the English teachers' opinion on the current speaking teaching and testing? (2). Is the OPIc speaking test appropriate in the Korea English class? and (3). What are the English education students' perceptions of the OPIc-based speaking test for English classes? To answer the first research question, a survey was conducted targeting one hundred and forty-seven teachers. The result of the survey shows that Korea English teachers' great concern on the English teaching and speaking test are "communicative competence," "scoring and criteria," and "condition and need." To answer the second research question, the OPIc speaking test for the class was analyzed and it was found that in terms of the communicative competence," "scoring and criteria," and "condition and need" issues, OPIc based speaking test is appropriate in Korea English class. For the third research question, Q methodology was used targeting English education students and the result shows that most English education students strongly agree to the statements that the OPIc-based speaking test has the advantage to improve communicative competence. This study may provide the information about creating and adopting tests for English classes and relating standardized test and the English classes.

국토기본법과 국토의 계획 및 이용에 관한 법률은 국토의 지속 가능한 발전을 위한 정책 및 계획을 규정하고 있다. 이를 효율적으로 달성하기 위한 수단으로GIS를 기반으로 공간의사결정 지원체계 구축에 대한 수요가 높아지고 있다. 이는 그 동안 행정업무를 위한 자료관리 중심의 정보화에서 공간자료분석을 기반으로 한 정보화에 대한 새로운 수요라고 할 수도 있다. 그러나 국토공간계획을 지원하기 위한 의사결정지원체계를 성공적으로 구축하기 위해 해결해야 할 많은 과제들이 있다. 본 연구는 국토공간계획을 위한 의사결정지원체계를 구축하는데 장애가 되는 과제를 파악하고, 해결방향을 제시하는데 목적을 두고 있다. 이를 위해 전문가를 대상으로 한 델파이 조사를 실시했다. 본 연구는 공간의사결정지원체계의 설계 및 개발에 영향을 미치는 주요 요인을 중심으로 research questions를 가지고 접근했다. 시스템 설계 관점에서 처리결과에 영향을 미치는 요인으로 입력되는 자료와 지식, 분석처리하는 방법, 인터페이스 등을 중심으로 research question을 설정했다. 시스템 개발과 관련하여 개발도구 확보, 이해관계자 참여 방안, 시스템의 지속성 확보 등을 중심으로 research questions를 설정했다. 마지막은 향후 공간의사결정 지원체계의 연구 및 개발을 효율적으로 수행하기 위한 파트너쉽에 대한 research question이다. 지금까지 국내에서 공간의사결정지원체계 구축과 관련해 기초적인 이론이나 방법론에 대한 연구가 미흡했다. 대부분 외국의 연구 및 개발사례를 소개하는 수준에 불과하다. 특히 공간의사결정지원체계를 구축하거나 운용하는 기반기술인 개발도구에 대한 기술수준이 상당히 미흡하다. 조사결과에서 공개소프트웨어 도입에 대한 필요성 강조가 이를 반증하고 있다. 또한 시민사회의 성숙, 다양한 사회단체 출현 등으로 국토공간계획 과정에 이해관계자 참여정도가 질적 양적으로 높아질 것으로 예상된다. 그러나 이에 대응하기 위한 기술, 기법 등에 대한 연구는 매우 미흡하고 단편적으로 관련 기술을 소개하는 정도이다. 국토공간계획 및 정책과 관련한 다양한 문제해결을 위한 공간의사결정지원체계를 구축하기 위해서 장기간에 걸긴 단계적 접근이 필요하다. 국토공간계획은 우리나라만의 자연 환경 및 인문환경의 특성이 반영되어야 할 것이다. 이를 위해 우리의 개발방법론, 우리의 기술이 개발되어야 하며, 이를 체계적으로 구현할 수 있는 협력체계 구축이 필요하다.
