  • This study examined the multicultural efficacy and job satisfaction of multicultural family visiting instructors. The subjects were 750 visiting instructors from 140 multicultural family support centers in Seoul, 6 metropolitan cities, 9 provinces, and other cities and counties. Data were analyzed through frequency, percentages, Pearson's correlations, One-way ANOVA, Scheff$\acute{e}$ post-hoc test, independent t-test, and stepwise multi-regression using PASW 18.0. The findings are as follows. First, there were statistically significant differences in all subscales of multicultural efficacy according to the teaching experiences of the multicultural family visiting instructors. On the other hand, there was a statistically significant difference only in trust in the relationships with multicultural families according to the teaching experiences of the multicultural family visiting instructors. Meanwhile, the independent t-test showed that there was a significant difference only in satisfaction regarding treatment and salary according to the assigned work. Second, the stepwise multi-regression models revealed that three subscales (job performance, trust in the relationships with the multicultural families, job aptitude) of job satisfaction were influenced by multicultural efficacy according to both the teaching experiences and assigned work, but this was no the case for satisfaction about treatment and salary. Regardles of teaching experience or assigned work, teaching efficacy in multicultural efficacy affected all subscales of job satisfaction except for satisfaction about treatment and salary. The implications for future studies are also discussed.

  • This study aims to show how scientifically gifted students think in terms of Thinking Style Inventory based on Sternberg's theory of mental self-government and to examine the relationships between their thinking styles, intelligence and creativity. Two hundred and sixty-six middle school students (169 boys, 97 girls) who enrolled in a gifted education program participated in this study. Results indicated that scientifically gifted students prefer legislative, liberal, judical thinking styles, in comparison to general students, known to be related to creative and critical thinking rather than executive and conventional styles. There was no significant correlation between any of thinking style sub measures and Raven' Matrices and Scientific Aptitude Test, but some correlations were found among the sub measures of thinking style and TTCT. Whereas liberal students gained high originality scores, conventional students gained low fluency scores. Also, judical thinking style showed significant correlations with originality and flexibility TTCT sub scores. In sum, this study showed the characteristics of thinking styles of scientifically gifted students and provided implications for gifted education based on the findings presented.

  • Higher grade elementary school students who have superior cognitive abilities need education of basic principles of computer or programming rather than computer in education. In this study, all the errors occurring while elementary school students wrote and executed programs were collected. in the method of predicting and dealing with possible-to-occur problems on programming education of the higher grades (4th, 5th and 6th grades) during their optional special activities or during talent aptitude activities after school, classified by type and analyzed. If the errors analyzed are put to practical use, optimal programming curriculums could be written and such curriculums could be a great contribution to induction of learning effect and interest on teaching learning. It was found by analyzing the errors collected for this study that the most of elementary school students during programming felt difficulties in simple errors by poor use of software and in simple coding by poor use of reserved words in English. In the next, students occurred errors by difficulties in understanding grammar. It was exposed that these error types were the opposite phenomena to those analyzed by commercial software developing companies, however, it is predicted that if teaching learning is setting improved, the same phenomena could be found desirably.

  • In test with multiple choices, it is necessary to have the position of correct answers of each question spreaded evenly over all the questions in order to minimize the influence of answering tendency of test takers with preference to specific position of multiple choices. The scores of tests with correct answers in specific positions would not reflect exactly the academic aptitude of examinees who do not know correct answers but have the biased answering tendency. In this paper, we have randomness test for the positioning of correct answers at the 2017 College Scholastic Ability Test (CSAT) using Bartels rank test, the Wald-Wolfowitz runs test, the turning point test, the Cox Stuart trend test, the difference sign test and the Mann-Kendall tank test, etc. We also do independence test between the location of correct answer and the allocation of score in each question, for it may result in overestimating the test-taker with specific position preference in marking correct answers.

  • This study was performed to provide basic rheological data of dandelion root concentrates in order to predict their processing aptitude and usefulness as functional foods material. The hot water and 70% ethanol extracts of dandelion root were concentrated at 5, 20, and 50 Brix, and their static viscosity, dynamic viscosity, and Arrhenius plots were investigated. Almost all hot water concentrates showed the typical flow properties of a pseudoplastic fluid, but evaluation using the power law model indicated that the 70% ethanol concentrates showed a flow behavior close to a Newtonian fluid. The apparent viscosity of hot water and 70% ethanol concentrates decreased with increasing temperature. Yield stresses of hot water and 70% ethanol concentrates by Herschel-Bulkley model application were in the range of 0.026 - 1.368 Pa and 0.022 - 0.238 Pa, respectively. The effect of temperature and concentration on the apparent viscosity was examined by Arrhenius equation. The activation energies of hot water and 70% ethanol concentrates were in the range of $8.762-23.778{\times}10^3\;J/mol{\cdot}kg$ and $3.217-20.384{\times}10^3\;J/mol{\cdot}kg$ with increasing concentration, respectively. Storage (G') and loss (G") moduli were generally increased with increasing frequency. For the 70% ethanol concentrates, G" predominated over G' at all applied frequencies and so they showed the typical flow behavior of a low molecular solution. However, for the hot water concentrates, G' predominated over G" at more than 1.9 rad/sec (cross-over point) and so they showed the typical flow behavior of a macromolecular solution.
