Purpose: The purpose of this study was to investigate the relationship between high school students' self-differentiation, family function and their level of stress. Method: A questionnaire which consisted of questions on general characteristics of the high school students, and 36 questions on self-differentiation, 17 questions on family function, and 37 questions on level of stress was used to collect the data. Participants were 201 second grade high school students from Bucheon City. Descriptive statistics, T-test, ANOVA, correlation and multiple regression were used with SPSS 10.0 to analyze the data. Results: The mean scores for self-differentiation, family function, and levels of stress were 3.27, 3.39, and 2.61 respectively. The relationship between self-differentiation and level of stress revealed a significant negative correlation. The relationship between self-differentiation and family function showed a significant positive correlation. The relationship between family function and stress level showed a significant negative correlation. Conclusion: The results of the study show that variation in level of stress was related to family regression, recognition/emotional function, family projection, role recognition and emotional support and emotional cutoff which together explained 40.9% of the variance in level of stress.

Most questions made for remote examinations on web-based education system use methods of making questions using fixed questions or randomly using item pools or automatically using degree of difficulty. Particularly, automatically selection methods using degree of difficulty is the kernel of a question that objectivity of examination questions by degree of difficulty adjustment based result of examination. This paper is use automatically selection methods for examination on web-based education system. Therefore we present new algorithms of mediateness degree of difficulty as regards education ability of students for adjust the degree of difficulty. We identified this algorithms is more effective as compared with previously algorithms on web-based education system

When you present a medical scientific paper or give a lecture in English, It is important to visit your presentation room in advance to gain familiarity with the controls and the computer. You can check how to use the mouse or laser pointer and determine where the microphones are. You should meet the Chairman and introduce yourself. You may ask the Chairman any questions you have. I am confident this strategy will work for beginners because they are usually nervous before their presentations. Most Chairmen prepare one or two questions for the presenters to stimulate discussion. Speaking with the Chairman also allows you to determine the type of English that he or she speaks (i.e., French-English, Spanish-English, and British-English). You need to be comfortable with the Chairman's English before the presentation because the Chairman will repeat the questions for you when you do not understand a question from the audience. Although I have given a number of lectures and moderated many scientific sessions and symposiums in English over the past 20 years, it is still difficult and stressful for me to do these in English because English is not my first language. To overcome the problems, I have written down the questions and useful English expressions that I have received during or after my presentation because I found them helpful for my next presentation. I hope the examples will be of great help to you.

This study aimed to investigate the characteristics of pre-service elementary teachers' understanding about scientific inquiry in terms of designing exploration and reasoning that is used to formulate explanations based on evidence. The research context was an open inquiry with using the Science Writing Heuristic (SWH) template in which participant students were not provided with inquiry questions. As data, lab. 39 pre-service elementary teachers participated in this study while taking their science methods course. Analyses of the reports were framed by the cognitive processes of inquiry (Chinn and Malhotra, 2002) and each report was coded and analyzed by the framework of inquiry (Tytler and Peterson, 2004). Results showed that groups' works that utilized the SWH template encouraged the participants to interact each other about scientific inquiry. They came up with more relevant and testable questions for their scientific inquiry. It implicates that children will be able to have chances of testing their own questions more properly by using the SWH template in science classes just as the participants did in this study. The use of the SWH template would help pre-service teachers to teach appropriately how to test inquiry questions to their students in the future. Discussion was made to figure out the characteristics or Korean pre-service elementary teachers' understanding about scientific inquiry.

Purpose: A large number of attributes with mixed levels are often considered in the conjoint analysis. In the cases where attributes have two or three levels, we research on the efficient design of survey questionnaire to estimate all the main effect and two factor interaction effects with a reasonable size of it. Methods: To reduce the number of questions in a questionnaire, the balanced incomplete block mixed level factorial design with minimum aberration was proposed by Lim and Chung (2016). Based on the number of questions and that of the respondents in that design, D-optimality criterion is adopted to find efficient designs where the main effect and two factor interaction effects are estimated. Results: The list of the number of questions and that of the respondents in efficient designs for survey questionnaire are recommended based on the D-efficiency of each design and the proposed selection criteria for the number of both questions and the respondents. By analyzing all the respondents survey data generated by the simulation study, we find the proper model. Conclusion: The proposed methods of designing survey questionnaires seem to perform well in the sense that how often the proper model is found in a simulation study where all the respondents survey data are generated by the simulation model.

The importance of pedagogical content knowledge(PCK) has been recognized in learning science teaching. PCK is based partly on the essence of subject matter knowledges. Therefore, the effective teaching of science content knowledges is fundamental in preservice education of student teachers. But, particularly the science curriculum of primary teachers' colleges is composed of less lessons than needed. This research was executed to identify the content and context of earth science which were contained in questions by student teachers These questions which were written by the students about the earth science content in elementary science texts and teachers' guide books were collected and analyzed. Frequency and context concentration of questions about the themes of contents were obtained. In each unit of the text books, scatter diagrams of question frequency and context concentration of themes showed various features. The main results were as follows. first, in case of the units which contents ate composed of themes expected to be experienced in everyday life, the question frequency and context concentration showed positive correlation between them. But, other units, which everyday life experiences are not expected to influence, did not show distinct correlation.

Purpose: The purpose of this study is to examine adolescents' knowledge and attitudes towards dementia and to provide basic data for educating about knowledge of dementia and strengthening positive attitudes towards dementia. Methods: This study used a descriptive research design. The subjects were 502 middle and high school students. A questionnaire organized by 16 questions of knowledge and 10 questions of attitudes towards dementia was used. Results: The subjects' knowledge level of dementia was low, and average score was $8.89{\pm}2.95$. The questions with low rate of correct answer were "Dementia is caused by several dozens of diseases such as internal medicine, neurology, psychiatry, etc.", "In spite of the dementia, patients can enjoy their favorite things." The subjects' average score of attitudes towards dementia was $3.72{\pm}0.58$. Questions of negative attitudes were "I don't want to be closed to patients of dementia.", "I watch information or prevention about dementia in mass communications media." The relationship between dementia-related knowledge and attitudes showed positive correlation. Conclusion: The result means the mediation is necessary for improving dementia-related knowledge and strengthening positive attitudes in adolescents. The education programs should be proceeded to provide adolescents with correct information about dementia.

Purpose: The purposes of study was to evaluate the effect of debriefing using reflection questions and writing on the critical thinking disposition, self-efficacy, and clinical judgement ability in simulation of post-operative care of abdominal surgery. Methods: The research method was a nonequivalent control group no-synchronized design. The study period was from August 22 to 30, 2016. The subjects were comprised of 34 people in the experimental group and 36 in the control group. In a simulation session for post-operative care of abdominal surgery, the treatment of the experimental group was to debrief for 30 minutes using Lasater's reflection questions and writing. For the control group, a typical debriefing was conducted in the same environment. Results: Critical thinking disposition, self-efficacy, and clinical judgement were significantly higher in the experimental group than the control group. Conclusion: To enhance the critical thinking disposition, self-efficacy, and clinical judgement of nursing students in simulation, it is recommended to debrief using reflection questions and writing.

This study focuses on the development of checklist on articulating reading appreciation, which will be used as the initial data for book recommendation for library users. As reading comprehension is prerequisite for reading appreciation, researchers analyzed research articles on reading comprehension to find out the core factors on reading comprehension and categorize them. Studies on reader response theory and literacy education were also examined: key words and phrases that will stimulate readers' response to reading were extracted and formed as questions. These questions were reviewed by experts on reading education. The final checklist consists of 14 questions - 4 questions on literal·inferential comprehension, 3 on evaluative comprehension, and 3 on appreciative comprehension.

We may consider the following three fundamental epistemological questions concerning cosmology. Can cosmology at last understand the origin of the universe? Can computers at last create? Can life be formed at last synthetically? These questions are in some sense related to the liar paradox containing the self-reference and, therefore. may not be answered by recursive processes in finite time. There are, however. various implications such that the chaos may break the trap of the self-reference paradox. In other words, Goedel's incompleteness theorem would not apply to chaos, even if the chaos can be generated by recursive processes. Internal relations among cosmology, epistemology and chaos must be investigated in greater detail.
