While the statistical concept 'order statistics' has a great number of applications in our society ranging from industry to military analysis, it is not necessarily an easy concept to understand for many people. Adding some interesting simulation activities of this concept to the probability or statistics curriculum, however, can enhance the learning curve greatly. A hands-on and a graphic calculator based activities of a missile simulation were introduced by Kim(2003) in the context of order statistics. This article revisits the two activities in his paper and point out a dilemma that occurs from the violation of an assumption on two deviation parameters associated with the missile simulation. A third activity is introduced to resolve the dilemma in the terms of a kernel density estimation which is a nonparametric approach.

The purpose of this study was to develop the ESD program related to creative-experience activity, and to examine the effect of its application. The program was composed of 13 sessions for fifth-grade class in elementary school, including all of the environmental, economic, and social aspects of ESD. This program was connected to the domains of creative hands-on activities, that is, career activities, club activities, self-regulated activities and voluntary service activities. The results was as follows. First, the experimental group to undergo the ESD program related to creative-experience activity did not show significant differences in environmental literacy compared to the control group, but it is proven that this program contributed to the improvement of learners' environmental emotion, skill, and participation. Second, the experimental group did not show significant differences in scientific attitude compared to the control group, but it was considered to affect the elementary students' criticism, self-esteem, and patience in positive and effective manner. In conclusion, more ESD program that cultivate elementary school students' environmental literacy need to be developed continuously, and more intensive research should be conducted to earn better understanding of ESD.

This study carried out a horticultural program for people with mental disabilities to determine suitability of the horticultural activity program and to actually apply to vocational rehabilitation. The program was carried out in 16 sessions from April 12 to June 7, 2018 with nine people with a strong will to participate in vocational rehabilitation at a health center for persons with mental disabilities. The tools used were the Horticultural Activity Performance Assessment (psychological behavior) and Purdue Pegboard Test that examines functions of hands and arms. The subjects sold the products they made during class time and obtained the profits. After the program, the scores increased with a significant difference (p = .000) in the psychological behavior area of the Horticultural Activity Performance Assessment. Hand and arm movement also showed continuous improvement along the program with a significant difference (p = .000), as well as finger dexterity also with a significant difference (p = .018). The net profit was 314,000 KRW (subtracting cost of goods 314,000 KRW from total sales 628,000 KRW). The profit was shared equally among the nine subjects, each receiving 34,900 KRW. Therefore this study proved horticultural activity class is suitable for vocational rehabilitation of people with mental disabilities proved by the positive effects. We also expect that the subjects will be able to make more profits if they learn more skills, since they are interested the process of making such profits.

The purpose of this study was to investigate the responses of the trunk muscle during expected and unexpected sudden loadings of the hands on the sagittal plane. Twenty, young healthy adults(male 10, female 10) were participated to two different loading conditions : expected and unexpected sudden loadings. Different weights were dropped in hand : 5lb, 6lb, 7lb for male, and 3lb, 4lb, 5lb for female. EMG activity of rectus abdominalis and erector spine muscle were collected. Rectus abdominalis and lumbar erector spine muscle activity significantly increased in unexpected sudden loadings than expected sudden loadings(p<.05). This results indicate that co-contraction of abdominal and back muscle contribute for dynamic spinal stability during expected or unexpected activities of daily living. Preparatory adjustments can be made which reduce the postural perturbation to sudden load and prevent low back injuries.

Under this research, the survey is made on the definitive influence of the first-year education process of the science focus school for each of humanities, science and science core courses and the level of satisfaction of the non-curriculum experiment activity program for each course to find out the effectiveness of the first-year education process of the science focus school. For this purpose, this research has set three research issues. First, By clarifying the research result through the first-year education curriculum for science core school, noticeable change was observed for science focus school students through the change of attitude related to science for each desired course of students. Second, in the self-directed learning characteristics change, there was meaningful change for each desired field of students. Students hoping for humanities curriculum had great help in improvement of creative thinking for openness, creativeness and the like, but the influence was slightly insufficient in the moderation and control capability on themselves in learning attitude. Third, By analyzing the research result comprehensively, the first-year education curriculum for science core school provides high level of tailored science learning for the science focus school students and the level of satisfaction for students was significantly high.

본 연구에서는 학생중심의 수학 및 과학 교육법으로 화제가 되고 있는 STEM교육의 유래와 STEM 교육을 대학교육에 부분적으로 적용하고 있는 Hands-on교육과 일본대학의 수리공교육의 사례를 조사한다. STEM교육은 학생들이 기술과 공학의 문제에서 수학의 필요성을 자각하도록 하고, 더 나아가 수학교과에 대한 수동적 학습태도를 능동적으로 바꾸는데 적합한 방법으로 부상되고 있지만, S(과학), T(기술), E(공학), M(수학)의 물리적 융합이 아닌 화학적 융합으로써 현행 대학 교과과정에 바로 적용하기에는 다소 무리한 측면이 있다. 따라서 실제 프로젝트에서 고려되어야 하는 T와 E를 졸업작품에서 스스로 찾도록 하고, 이 자발적인 발견을 수학교과목과 연계하는 Pseudo-STEM교육법을 제안한다.
