Objectives: The purpose of the study is to investigate the relationship between the personality types and satisfaction of education satisfaction in dental hygiene students. Methods: A self-reported questionnaire was filled out by 898 students in Busan, Gyeongnam, and Ulsan from March 2 to 25, 2014. Data were analyzed through t-test, correlation analysis, and multiple regression analysis. The instruments used personality types and satisfaction of education. The personality types was adapted from Korean Eyesenck Personality Questionnaire that was modified by Lee on the basis of Eysenck Personality Questionnaire(Eysenck & Eysenck, 1971). The questionnaire consisted of 44 questions including extroversion factors(18 questions) and neurotic tendency(26 questions). The questionnaire was score by Likert 5 scale. Cronbach alpha was 0.835 in the study. The neurotic tendency consisted of 26 questions and the higher score showed the higher neurotic tendency. Cronbach alpha was 0.927 in the study. The instrument for satisfaction of education was adapted from Kim and Go and partly modified. The instrument was categorized into dental hygiene department satisfaction(6 questions), major satisfaction(6 questions), facilities satisfaction(4 questions), lecture satisfaction(7 questions), and faculty satisfaction(4 questions). The instrument was scored by Likert 5 scale. Cronbach alpha of education satisfaction was 0.928 in the study. Results: Extroverted students showed 3.70 point which was the highest score in the department satisfaction(p<0.001). Less neurotic students showed 3.68 point which was the highest score in the department satisfaction(p<0.001). There was a strong positive correlation between the major satisfaction and department satisfaction(p<0.01). The personality types that affected the education satisfaction were related to the extroverted students and less neurotic students(p<0.01). Conclusions: The personality types had much influences on the satisfaction of the major and academic accomplishment.

The purpose of this study was to investigate the home economics pre-service teachers' verbal interactions during their teaching practicum. For this purpose, the class interactions of four pre-service teachers were recorded, and the data were analyzed using advanced Flanders' verbal interaction analysis. The major findings are as follows: First, the item with the highest proportion of occurrences consisted of the pre-service teachers' 'lectures', 'nonverbal conditions' and 'asks questions'. 'forms a positive learning atmosphere' and 'praises or encourages' exhibited fewer occurrences, and there was little 'giving direction', 'criticizing students or justifying authority'. Second, the instances of class interactions appeared in the form of 'asks questions-student talk response' or 'lecture-asks questions', and in the last class were 'ask questions-student talk initiation' and 'accepts or uses ideas of students'. Third, trends of verbal interactions tend to be generally indirect, and students' remarks have appeared acceptable and compassionate. Fourth, according to expert analysis, 'class management questions' and 'diffusion questions' have increased. Pre-service teachers can guide students through their learning activities, and students can expand their thinking through the teachers' questions. As these results demonstrate, self-study analyses of pre-service teachers and active support in field are needed.

The purpose of this study is to review existing research trends to find highly reliable tools for measuring inconsistencies in parenting attitudes for adolescent children. We reveal factors that heavily affect reliability and feasibility of these tools and compose stable measurement items. We found a total of 37 items with high reliability and feasibility comprising six questions on affection, three questions on childcare, nine questions on interest, seven questions on demands, five questions on neglect, and seven questions on abuse. We surveyed first to third-year high school students in public and private schools nationwide and carried out statistical analysis for the 1,020 respondents. Upon analysis, questions were removed if they showed low factor loading (less than 0.6) for the father and mother in each of the 37 measurement items. Only questions that could be used for both the father and mother were extracted to carry out exploratory factor analysis. Eight questions were were deleted: five on interest, one on demands, one on neglect, and one on abuse. The final 29 questions were selected for the measurement tool. Cronbach's Alpha coefficient was used to analyze reliability, which showed high reliability values ranging from .857 to .931 for the father and mother. Therefore, these inspection tools for inconsistent parenting attitude were both reliable and feasible.

This paper presents a factor-analysis based questionnaire categorization method to improve the reliability of the evaluation of working conditions without influencing the completeness of the questionnaire both in Taiwanese and Chinese construction enterprises for structural engineering applications. The proposed approach springs from the AI application and expert systems in structural engineering. Questions with a similar response pattern are grouped into or categorized as one factor. Questions that form a single factor usually have higher reliability than the entire questionnaire, especially in the case when the questionnaire is complex and inconsistent. By classifying questions based on the meanings of the words used in them and the responded scores, reliability could be increased. The principle for classification was that 90% of the questions in the same classified group must satisfy the proposed classification rule and consequently the lowest one was 92%. The results show that the question classification method could improve the reliability of the questionnaires for at least 0.7. Compared to the question deletion method using SPSS, 75% of the questions left were verified the same as the results obtained by applying the classification method.

Objectives: The purpose of the study is to investigate the relationship between professional vocation and ethical inclination in clinical dental hygienists. Methods: A self-reported questionnaire was filled out by 221 clinical dental hygienist in Busan and Kyeongnam from April 1 to 30, 2014. The questionnaire consisted of structured questions including demographic characteristics(9 questions), vocational calling(9 questions), deontology(12 questions), asceticism(13 questions), and utilitarianism(8 questions). Questionnaire was carried out by Likert scale. Data were analyzed using the statistical package SPSS Window 19.0 for frequency, mean and standard deviation analysis, t-test, one-way ANOVA and linear regression. Results: There was a significantly positive correlation between professional vocation and ethical inclination. The deontology was associated with education, dental service career, duty hours, and number of clients in multivariate analysis after adjusting for socio-demographic characteristics and professional vocation. Asceticism was also correlated with education, and utilitarianism was closely associated with vocational calling, work place, number of clients, and monthly income. Conclusions: It is necessary to develop the curricula including vocational calling and ethical inclination in the dental hygiene education. The dental hygienists should learn the ethical and vocational calling as a professional career.

In this research, in order to obtain teaching/learning implications for effective use of questions when teaching number and operation area, the types of questions presented in chapters of number and operation area of 2015 revised elementary math textbooks and the function of questions were compared and analyzed by grade cluster. As a result of this research, the types of questions presented in chapters of number and operation area showed a high percentage of occurrences in the order of reasoning questions, factual questions, and open questions not calling for reasoning in common by grade cluster. And reasoning questions were predominant in all grade clusters. In addition, in all grade clasters, the proportion of questions acting as a function to help guess, invention, and solving problems and questions acting as a function to help mathematical reasoning were relatively high. As such, it can be inferred that the types and functions of the questions presented in chapters of number and operation area are related to the characteristics of the learning content by grade cluster. This research will be able to contribute to the preparation of advanced teaching/learning plans by providing reference materials in the questions when teaching number and operation area.

In order to globalize Korean foods successfully, it is necessary to understand foreigners' attitudes about ethnic foods and how foreigners perceive Korean foods. It would be valuable to survey the degree of interest from foreigners when purchasing Korean foods. Thus, a survey was performed on the most common tourists in Korea, the Japanese, Chinese and Americans. 313 respondents completed the survey on ethnic foods (16 questions), purchasing intention of Korean foods (3 questions), and socio-demographic conditions (9 questions). Factor analysis and reliability analysis were conducted to identify the indicators of attitudes toward ethnic foods. Correlation analysis was conducted to confirm the relation between attitudes toward ethnic foods and Korean food purchasing intention. From the results of factor analysis, 5 factors emerged from the 13 out of 16 questions; and were labeled new food seekers, ethnic food seekers, familiarity seekers, new taste seekers and challenge seekers. Items were analyzed to determine the differences according to nationality by using the ANOVA, and it showed that Americans have the highest Korean food purchasing intentions. The regression analysis indicated that attitude factors on ethnic foods, new foods and new taste seekers are strongly related to Korean food purchase intentions.

Through quantitative analysis of two math classroom videos, combined with the relationship between types of teachers' questioning and students' answering, it is concluded the following problems are in the mathematics classroom teaching: (1) The time of teachers' questioning is longer, the number is too much, with managerial questions and prompting questions is given priority to; (2) Teachers' questioning time is longer than students' answering time, comprehensive answer is more, creative answer is little; (3) In the classroom questioning, students' participation is low; and (4) There is a significant correlation between types of teachers' questioning and length of waiting time after questions. In response to these phenomena, we propose strategies as follows: pursuit of timeliness of classroom questioning, reducing inefficient questions, to increase efficient questions, adopting different waiting strategies for different questioning types, to mobilize students' thinking activities, and improving students' participation etc.

This study was to evaluate the suitability of scientific questions as qualification examination for high school graduation by content validity and item response with three examinees and two preliminary examinees. As a result, scientific questions were concentrated on two units of six units of total, and application appeared to be lacking problem area by 8% compared to understanding and application. Examinees and preliminary examinees chose correct answers most by hap or guess, sometimes by experience or common sense, and the least by scientific concept. In addition, they could chose correct answers by hap or guess because there were words that implied the correct answer in questions and answers, or because they could compared and/or analyzed questions and answers. With these results, two proposals were suggested as follows; (1) scientific questions of qualification examination for high school graduation should measure basic scientific literacy. (2) specific criteria for science literacy in qualification examination for high school graduation should be set.

Objectives: The purpose of this study was to investigate the oral health condition, recognition, and practice in prisoners. Methods: A self-reported questionnaire was filled out by 143 prisoners in three jails from April 7 to June 2, 2014. The questionnaire consisted of 35 questions including 5 questions of general characteristics of the subjects, 4 questions of subjective oral health condition, 5 questions of management of oral health care, 11 questions of oral health recognition, and 10 questions of oral health practice. The questionnaire was adopted and modified by Shon et al. and Cho & Choi and measured by Likert 5 scale. Cronbach's alpha was 0.845 in recognition questions and Cronbach's alpha was 0.826 in the practice questions. The data were analyzed using SPSS 18.0 for t-test, one-way analysis of variance(ANOVA) and Pearson's correlation analysis. Results: 21.0% of prisoners answered that their perceived oral health condition was good. Those who received the dental treatment accounted for 42.0% and 12.6% of them took the oral health education. There was a significantly negative relationship between perceived oral health and oral health recognition(p<0.05). The oral health recognition showed positive influence on oral health practice(p<0.001). Conclusions: In general, prisoners did not receive the proper care of oral health in jails. Therefore, It is desirable that we need to set up a oral health care system for prisoners.
