What is learning in the math classroom? Does a new term need to be coined for learning? Is the term over-used and it has lost it meaning? The responses of one hundred five teacher-candidates and graduate students were coded using the five levels researcher designed rubric which was modeled after Bloom's Taxonomy for depth of knowledge. The effects of understanding learning include the preparation of lesson plans, classroom instruction, the guiding of student learning, and the professional development of teacher leaders.

We investigated the education process of an environmental experiment in middle and high school. The major objective was that students understand about biological toxicity of endocrine disruptor. We used bisphenol A in environmental experiment to educate them about the effects of endocrine disruptor. The test animal was zebrafish (Danio rerio, wild type) which is very easy to use in the school experiment class. We educated the high school students (n=25) in Suwon through this teaching program. Finally we analyzed the effect of research education between two groups, education students (test) and non-education students (control). This experiment showed there were some positive effects on environmental reorganization of students. They understood the affect of endocrine disruptors in fish and man. Specifically, understanding the importance of preservation of ecosystem increased in the test-education group.

The purpose of this study was to investigate the differences between medical college students and graduate school students with regard to the factors that shape career choice and specialty indecision. One hundred and thirty-three students from a medical school participated in this study. The students completed a survey, which collected information on career choice, specialty indecision, and career adaptability. Significant differences were found between high and low career adaptability groups in factors that affected specialty choice and indecision. Students with high career adaptability were significantly more affected by 'intellectual content of specialty,' 'ages and characteristics of patients,''patient contact experience during the early years of medical school,' and 'greater opportunity for research.' Among the specialty indecision factors, students with high career adaptability were affected by 'several specialties equally appealing to me' and 'many interests,' while students with low career adaptability were affected by being 'unaware of my abilities,''unaware of my interests' and having 'learned my choice was not possible for me.' The factor having the greatest influence on specialty indecision was 'need more information and support,' and there were no significant differences in these factors between the two groups. The results suggest that the development of career counseling and education programs need to be designed for medical college students and graduate students in terms of career adaptability and specialty indecision.

The general learning method aims at conveying knowledge by conveying the contents of the learning set to numerous of learners. However, such a method is difficult to induce the interest of the learner, and the unilateral delivery method has a disadvantage in that the concentration of the learner can be lowered and the overall academic achievement can be lowered. In order to solve this problem, the gay learning method which induces the interest of the students themselves is studied, and the gay learning game which combines the education and the game can influence the learning by inducing the interest of the student. In this paper, we propose a method to prevent the forgery and falsification of the blockchain, which has been widely discussed by the 4th Industrial Revolution, as a card game, And suggests ways to contribute to the development of the process.

본 논문은 MPEG-4 기반의 모바일 비디오 서비스 환경에서 발생하는 화질열화 현상의 하나인 블륵킹 현상을 제거하는 기법을 제안한다. 제안된 기법은 전처리 과정과 3가지 모드의 디블록킹 필터 및 후처리 과정으로 구성되어 있으며 각 모드는 블록경계의 특성에 따라 적용된다. 모드 1은 블록경계의 양쪽 모두가 평탄한 경우에 해당하며 가장 강한 필터를 적용한다. 모드 2는 블록경계의 한쪽만 평탄한 경우이고 이때는 비대칭 필터를 적용한다. 모드 3은 블록경계를 중심으로 양쪽 모두 복잡한 경우이고, 이 경우에는 블록경계의 주파수 특성을 고려하여 화소값을 보정한다. 전처리 과정에서는 각 필터의 모드를 올바르게 선택하도록 블록 내부의 불필요한 신호를 제거하고, 후처리 과정에서는 대각선 에지와 블록의 모서리가 만나는 경우 발생하는 corner outlier를 제거하여 주관적 화질을 향상시킨다. 실험결과에서 제안한 방법이 PSNR 관점에서 후처리 과정을 거치지 않는 비디오의 경우와 비교하여 약 0.7dB, MPEG-4 디블록킹 결과와 비교하여 약 0.4dB 향상됨을 보인다.

Purpose: The purpose of this study is to examine the satisfaction level toward school sex education and its effect on character cultivation by reconstructing a unit, sex and health, included in the current health education curriculum. Methods: The study is a mixed research which utilized both two-way ANOVA & MANOVA methods, and qualitative content analysis. A total of 279 middle school students participated in the pre-test and the sex education program using the reconstructed curriculum. Then, a total of 253 participated in the posttest. Results: The results showed an increase in the satisfaction level toward school sex education (p<.05) and in character (p<.05) in both male and female students. There was no significant difference between male and female students. In the total test for character cultivation, there were no interacting effects between the test and gender (p>.05). Also, in the qualitative analysis, the program helped students to build character including self-care skills Conclusion: By revising the unit of sex and health to meet the needs and demands of the students, curriculum reconstruction increased the students' satisfaction and had a positive effect on their character cultivation.

Linear motor can be directly applied to the system needed linear motions without rotary motions. To control high-speed and high-resolution, the development of the linear motors is recently required in the high-integrated and speed process industry This paper presents thermal and vibration analyses as well as measurement standards of the newly developed linear motors through analyzing the thermal behaviors and vibration characteristics of the advanced products. The thermal measurements are conducted for comparing the developed linear motor with the advanced linear motor and the Finite Volume Method(FVM) is used to identify the measurement results. And then the vibration measurement are carried out in the developed and advanced linear motors with respect to the speed. To identify the measurement results, the Finite Element Method is utilized in the developed and advanced linear motors, respectively. The FVM, FEM, and experiments make it possible to understand these characteristics. The improvement is suggested through their results conducted experiment and analyses.

This study aims to compare the difference between the recognition of professionalism and teaching efficacy of the gifted education teacher by majoring in education for the gifted from the graduate school. The subjects were 44 graduate students in gifted education major and 56 gifted education teachers of elementary school who did not major in the education for the gifted. The results were as follows. First, the education for the gifted children majors showed higher statistical significance in the subject knowledge, the instructional strategies, the understanding gifted student, personal efficacy and outcome expectancy than the teacher who did not major in the education for the gifted children (p<.05). Second, in the results of Two-Way ANOVA by the major status in education for the gifted children and the gender, there was the interaction effects in the subject knowledge, the understanding gifted student, personal efficacy, and the females were influenced by the recognition of professionalism and teaching efficacy by the major status in education for the gifted children more than males. In the results of analysis on the major status in education for the gifted children and career for gifted education, the instructional strategies and personal efficacy showed the significant interaction effect (p<.05). Third, in the results of analysis on the relations between the recognition of professionalism and the teaching efficacy, all subordinate scopes of the recognition of professionalism and teaching efficacy showed the significant positive correlation (p<.05). In the results of the multiple regression analysis, the subject knowledge and the instructional strategies have effects on the personal efficacy. So the majoring in education for the gifted children from the graduate school may have significant effects on development of the subject knowledge and the professionality of the instructional strategies of the gifted education teacher, further, it can be said that has positive effect on teaching efficacy.
