The logical assumption of the comparison question test (CQT) is that the guilty person pays more attention to the relevant questions than to the comparison questions, and that the innocent person pays more attention to the comparison questions than to the relevant questions. The purpose of this study was to verify the logic of the comparison question test using functional magnetic resonance imaging (fMRI). The participants were tested for brain responses during a mock crime and performed the CQT under guilty and innocent conditions. After brain imaging, we evaluated the psychological burden of responding to the relevant questions and comparison questions. In the guilty conditions, the degree of burden was higher for the relevant questions than the comparison questions, and there was no significant difference in the innocent conditions. The fMRI results showed that, in the guilty conditions, greater activation was observed in the right superior temporal gyrus and right inferior frontal gyrus when relevant questions were presented relative to comparison questions. Based on these findings, the logical assumption of the CQT was discussed.

This study was a quasi-experimental study to test a research question: Is the school library-assisted instruction effective in enhancing students' academic achievement? To solve the research question, 14 hours of school library-assisted instruction and traditional lecture were carried out to 164 9th grade middle school female students(82 of experimental group, 82 of control group). SPSS 12.0 was used for statistical analysis of frequency analysis, $x^2$-test, and t-test. The results showed that there was a statistically significant difference between the pre-test and the post-test in the total academic achievement scores of both experiment group and comparison group. There was a statistically significant difference between the pre-test and the post-test in paper and pencil test scores for comparison group. There were statistically significant differences between the pre-test and the post-test both in paper and pencil test scores and performance assessment for two groups. But there were no statistically significant differences between the experiment group and the comparison group in post-test pre-test gap of total academic achievement, paper and pencil test, and performance assessment scores.

In clinical settings, researchers often want to assess agreement between two measurements (or tests) of the same continuous variable. For example, when new point-of-care analyzer for testing blood glucose level were introduced clinicians need to compare results from standard or established laboratory method of measurement to those of new or point-of-care analyzer. The question in a method-comparison study would either of two different methods be used to measure the same variable equivalently. In this paper common misuse of statistical methodologies seen in the medical literatures such as correlation coefficient and paired t-test are discussed. The Bland-Altman technique has been widely used for this purpose and provides a graphic in presentation of the findings from a method-comparison study, with a mean value of measurement, this bias and the limits of agreement. For ease of application and interpretation of this technique we discussed the analysis procedure and illustrated with two worked examples. Finally, a number of alternative ways in which data can be analysed and reported in such studies were reviewed.

The purpose of this study was to compare personality existed in the populations of the mentally retarded with and without Down syndrome. For this purpose, two research questions were proposed. (a) Is there any difference of personality existed between two groups? (b) Is there any difference of sub-personality existed between two groups by disability degree? Participants in this are 159 people with mental retardation(the mentally retarded with Down syndrom: 82, the mentally retarded without Down syndrom : 77) in P and S cities. First of all, the reliability in measurement instrument was verified through a pre-study. For the first research question, t-test was used. And two way ANOVA was used to investigate the second research question. The results of this study were as follows:First, according to the result of t-test, there were significant differences of personality scores between two groups. And there were significant differences between the mentally retarded with and without Down syndrome regard to expectation of success, outerdirectedness, positive or negative responding tendency, curiosity among sub-personality factors. Second, the result of the two way ANOVA analysis, no meaningful statistically difference in personality by degree of the impairment. But It showed difference regard to effectancy motivation, expectation of success, curiosity among sub-personality factors between the mentally retarded with and without Down syndrome by impairment degree.

The purpose of thin paper is to test difference of the two question formats, open-ended and dichotomous choice formats, in the contingent valuation method using the estimated recreational benefits. The data were collected from the visitors at the Songnisan National Park. The recreational benefit based on the equivalent variation. The two question formats, but the same content, were asked of the same individuals. In this analysis, it was used travel cost and monthly income as the exogenous variables, which assumed a linear functional form for the WTP equation. The model assumed a bivariate normal distribution on the basis of the probit and tobit model concerning the censored zero WTP. The result showed no differences in the recreational benefits from the different question formats under a same respondent. The mean benefit was estimated 25.556 Won per 5 years per visitors.

1. Purpose This study has focused on response rates of the questionnaire which considered as a basic data to identify constitution for American. 2. Methods By analysing the tendency of the respondents who has defined constitution by clinical diagnosis and comparing of their answers, the result of their constitution analysis by our questionnaire were re-examed. The answer of each question to each constitution were tested how it is relevent to a scale of a constitution. Each item response rate on SF_SSCQ-A was analysed about those who had been tested and diagnosed as Taeyangin, Soyangin, Taeeumin, Soeumin respectively. 3. Results There were the 55 significant items; 13 Taeyangin items, 13 Soyangin items, 20 Taeeumin items, 9 Soeumin items. However, there were the 11 low response rate items (below 10 %) and 4 no response items.

The purpose of this study is to explore directions for improvement of teaching at college of engineering based on analysis of differences from course evaluation of students and instructors. Data was collected from 86 instructors' ratings on courses and their 3004 students' ratings on courses at college of engineering in a two-year, a three-year college and a University from 2010 to 2013. The results of the survey indicate significant differences in the statistics from the several questions between the instructors and the students as well as between the course in a two-year, a three-year college and in a University. First, instructors' self evaluation of the course is higher than students' satisfaction ratings of the course on the average. Instructors' self evaluation are high on the questions 'The subject was proper for the course', 'The course provided the latest theory and trend of the field', and 'Fairness and objectivity about the exams and the assignments'. Also, the difference between Instructors and students on the questions is significant in the statistics. The professor must make sure that students know well how to organize the course content and the method for feedback to test result and homework. Second, instructors have higher satisfaction ratings on the six questions and students have higher satisfaction ratings on the one question('Make students participate in the class effectively') at a two-year and a three-year college. However, students have higher satisfaction ratings on the three questions('Make students participate in the class effectively', 'Concern about students' learning process', and 'Use of E-learning and media equipments') and instructors have higher satisfaction ratings on the one question. It means instructors at a University feel pressure on a teaching and they are unsatisfied with their teaching skills. Third, the result of comparing six parts of the questions shows that students' satisfaction ratings are higher on 'Students participation' and 'Application of media equipments' parts whereas instructors' self evaluation are higher on 'Exams and assignments' part. Fourth, the question 'Make students participate in the class effectively' is significant in statistic based on comparison of instructors and students, and comparison of in a college and a University. Students' satisfaction ratings are higher than instructors' self evaluation.

It is necessary to obtain a fire resistance certification in order to use Fire Protection Coating in Korea. According to the fire test standards, columns have four heating sides and beams have three. In comparison with columns which are heated four sides equally, beams have three exposed sides and one unexposed up side. So the question arises as to there were the differences between the temperature of up side and others of beams in fire test. The purpose of this study is to consider the positions of thermocouples for beams through a comparative analysis of the temperature data obtained from fire certification tests.

The purpose of this study was to compare the effects of two different types of texts, which were narrative and expository, on the understanding of content. Elementary students' perceptions of the two types of the texts were also investigated. In the comparison of the effects on the understanding of the text contents, test scores of mind-mapping, closed-answer question, and essay test were used. The analyses of mind-mapping tests showed narrative text was more effective to figure out main concepts of the text throughout the mind-mapping test. But expository text was more effective in the hierarchical organization of the concepts. In the closed-answer questions and essay test, narrative text was more effective than expository text. However when the contents of text were difficult and complex, there was no meaningful difference between the two types of texts. The analyses of students' perceptions of the texts showed that narrative texts were preferred. Students perceived that the narrative text was more interesting and familiar. However, the perceptions of helpful text for their science learning were not different by the types of texts.

Since some warm-mix asphalt (WMA) concretes were known to show poorer rut resistance than the hot-mix asphalt (HMA) concretes, many studies were performed in efforts of improving its performance at high temperature. The reason is assumed to be due to the moisture remaining in aggregates dried at lower temperature. Therefore, not only the rut resistance, the crack resistance of WMA concrete was also in question. In this study, fatigue life of WMA concrete was evaluated in comparison with HMA using 3-point bending (3PB) beam test. The asphalt mixtures were prepared based on Korean mix-design guide using a 13 mm dense-graded aggregate and 6 binders; two HMA binders and four WMA binders. By 3PB fatigue test, normal (unmodified) and polymer-modified WMA concretes were evaluated in comparison with normal and polymer-modified HMA concretes at a low temperature (-5℃). The results showed that most of WMA concretes showed longer fatigue lives than HMA concretes, even though the same PG binders were used for HMA and WMA. This result indicates that the WMA concretes have stronger resistance against fatigue cracking than HMA at the low temperature, and this result is in contrast to the high-temperature performance test.
