This study has investigated the way to improve the communication skills emphasized in mathematics education, and analyzed the effects of Communication Oriented Mathematics Lessons on the mathematical disposition and the academic achievements. For this research, two groups of first grade students from D elementary school in Daegu city were selected which had been proved homogeneous in mathematical disposition and academic achievements via a preliminary test. The experimental group was given Communication Oriented Mathematics Lessons (COML) while the control group was given Traditional Classroom-based Instruction (TCI). COML were given along with first grade, first level mathematics for eight weeks, to improve communication skills of the students who were unfamiliar with mathematical communications. The schemes for the education include revising, summarizing, asking questions, and participating. The results of the study were summarized for mathematical disposition and academic achievements. First, COML is effective to evaluate the will to solve problems in the mathematical disposition of the students, and to make it useful for them to live their lives and to learn other subjects. Second, previous studies have shown contrary interpretations on the effects of COML. This study has found that it does not improve the students' scores on the original form of academic achievement test.

The purpose of this study was to examine the effects of Simulation as a Problem-Based Learning (S-PBL) on critical thinking disposition, self-efficacy, and learning attitude and to compare an ordinary least square and a quantile regression method in impacting factors on critical thinking disposition. 143 students from six classes were randomly selected from a total of ten fundamental classes were assigned 66 in the control group and 77 in the experimental group. The results were that the experimental group received S-PBL and improved their critical thinking disposition and self-efficacy compared to the traditional learning method. In ordinary least square, affecting factors on critical thinking were the learning method and self-efficacy and these variables explained 41.0% in the critical thinking disposition. The results of the quantile regression method showed that affecting factors of critical thinking disposition were learning attitude of 0.1 quantile to 0.7 quantile and self-efficacy of all quantiles, and learning attitude of 0.4, 0.6, and 0.7 quantiles. Conclusion: The S-PBL is an effective method for nursing students who have low critical thinking disposition score to increase critical thinking disposition. And instructors can actively use S-PBL to enhance critical thinking disposition as well as self-efficacy in class.

Directional words like 'ascending(升, sheng)', 'descending(降, jiang)', 'floating(浮, fu)', 'sinking(沈, chen) are technical terminologies of Oriental Medicine to express the directions of material medica functioning-at the phase of Qi-superiorly, inferiorly, exteriorly, and interiorly in human body, and are constituting one of the major principles in prescribing medicines. Lacking the objective methodology to measure or, at least determine Qi, However, we can not expect to secure meaningful data to verify those directional terms. This problematic situation caused chaotic discrepancy between theory and practice of Oriental Medicine. Thus, adopting the method of dynamic meditation 'Hanalmomjit' of Lux Vitae meditation society, by which various state of Qi-sensational movements can be expressed, we compared its moves with the directional terms of traditional canons in Oriental Medicine. In this thesis, the experiment of expressing materia medica via 'Hanalmomjit' is resulted out and compared with the terms, confirmed to have a certain meaningfulness. The new method showed these results below: Herba Menthae, described to have the disposition of ascending and floating, showed 60% of ascending movements in 'Hanalmomjit' experiment. Radix Rehmanniae Praeparata, described to have the disposition of descending and sinking, showed 50% of descending movements. Radix Glycyrrhizae, described to have plain disposition, showed 60% of central movements. Rhizoma Atractylodis and Pericarpium Citri Reticulatae, described to have the disposition of ascending and floating, showed also ascending movements. Cortex Magnoliae Officinalis, described to have the disposition of descending and sinking, showed also descending movements. In conclusion, qi-sensational movement of 'Hanalmomjit' for materia medica showed sufficient relations described in classics, proving itself to be useful method for objective demonstration of material medica.

As the importance of electronic commerce(EC) increases, some people argue that traditional commerce(TC) will ultimately give way to EC in the near future. Regardless of the type of commerce, however, it is the value factors of the customer that would formulate the direction of change in the market. This study investigates the influence of those value factors upon the attitude towards the type commerce and the repurchase intention of products and service. It also addresses the impact of the customer's risk disposition and level of confidence. A number of customer's value factors are hypothesized to affect the attitude, and the attitude in turn is expected to be related to the repurchase intention. Based on two hundred and ninety responses from the computer survey, the hypotheses are tested. The convenience, cost reduction, and information satisfaction factors affect EC attitude and repurchase intention. Similarly, the reliability, personal interaction, and shopping enjoyment factors affect TC attitude and repurchase intention. The comparison between EC and TC factors indicates the significant difference in the time saving factor in favor of EC. The personal characteristics such as risk disposition and level of confidence also influence the attitude and repurchase intention. The implications and limitations of this study are discussed. The value factors identified in this study may serve as important checklists for those firms already in EC and those intending to enter the market.

Purpose: This study focuses on investigating the effectiveness of simulation education on emergency management using a low-fidelity simulator as related to clinical skill performance, self-confidence, knowledge, learning satisfaction, and critical thinking disposition in new nurses. Methods: A pre-post test experimental design of nonequivalent control group was applied. Fifty-five new nurses were recruited, 28 nurses for the experimental group and 27 nurses for the control group. A simulation education for emergency management comprising knowledge lecture, team learning, skill education, team simulation, and debriefing was developed and implemented from Feb. 14 to 27, 2015. Data were analyzed with percentage, average, and standard deviation, chi-square, and t-test using SPSS. Results: The experimental group showed significantly higher knowledge (t=5.81, p<.001), clinical skill performance (t=10.08, p<.001), self-confidence (t=-6.24, p<.001), critical thinking disposition (t=2.42, p=.019), and learning satisfaction (t=4.21, p<.001) for emergency management compared with the control group who had traditional lecture education. Conclusion: The results indicate that a simulation education using a low-fidelity simulator is an efficient teaching method for new nurses to deepen their clinical skill performance, self-confidence, knowledge, learning satisfaction, and critical thinking disposition in learning emergency management.

Tessellations are the pattern of iterations of geometric symmetry and translation. We can find them in the works of Escher who is the famous Dutch artist, and the American Indean life. Also, we can find the beauty of tessellations in the Korean traditional house door, Buddist temple architecture, palace's fence, etc. In the article, the figures of patterns we present are bird, fish, cat, pig, elephant, penguin, child and horse riding man, including Escher's, which are constructed using the computer geometric program, GSP (Geometer's Sketchpad). We want to talk about girl's disposition toward mathematics related to the figures. If they are supported by this kind of interesting figures constructed by their own hands, students will have more interest in learning geometric figures.

In recent years there has been increasing interest in the issue of process centering in manufacturing process, The traditional process capability indices Cp, Cpk and Cpu are used to provide measure of process performance, but these indices do not represent the issue of process centering. A new measure of the process capability index Cpm is proposed that takes into account the proximity to the target value as well as the process variation when assessing process performance. However, Cpm only considers acceptance cost for deviation from target value within specification limits, do not includes economic consideration for rejected items. This paper proposes flexible process performance measures that considered quadratic loss function caused by quality deviation within specification limits, rejection cost associated with the disposition of rejected items, and inspection cost. In this model disposition of rejected items are considered under perfect corrective procedures and the absence of perfect corrective procedures.

This thesis analyzed the effects of cooperative learning blended with TAI(Team Assisted Individualization) and STAD(Student Team Achievement Division) models on the students' ability of problem solving in mathematics in order to discover what kind of effects would give to their ability of that, and would promote their disposition and attitude to learn mathematics. The results of this study were as follows : First, the learning method blended with TAI and STAD models was more effective in the students' ability of problem solving in mathematics than traditional learning method because of the blended model's characteristics; positive interdependence, individual accountability, team recognition, curriculum materials. Second, the learning method blended with TAI and STAD models was more effective in sub-elements - self-confidence, adaptability, will, curiosity and value - of mathematical disposition than traditional learning method. And the learning method blended with TAI and STAD models was more effective in sub-elements - self-consciousness of mathematics and interests - of mathematical attitude than traditional learning method. In conclusion, the learning method blended with TAI and STAD models could affect to not only the students' ability of problem solving in mathematics but also the students' several affective factors.
