Recently, core and neuromuscular training(CNT) is emerging as a clinically relevant tool to improve neuromuscular control and to prevent sports injuries. The purpose of this study was to examine the effect of a 12 weeks CNT program on the dynamic stability after drop landing. The subjects attempted drop landing onto the force platform on single foot from a 40 cm height distance. The collected data was used to calculate the dynamic stability index. The Dynamic stability index was derived by measuring the medial-lateral stability index(MLSI), anterior-posterior stability index(APSI), and the vertical stability index(VSI). In comparison to the control group, the MLSI and APSI showed no difference, yet, it resulted in higher VSI. The results of this study suggest that CNT is worthwhile to be considered as a way to improve neuromuscular control and to prevent traumatic injuries. However, the results are taking into consideration to discuss the limitations of CNT and suggested future approaches.

Objectives : This study were to find out differences in mother's oral health knowledge and oral health care behaviors and to find out factors that affected mothers' oral health care behavior for their young children. Methods : The survey was carried out with questionnaire about personal factor, cognitive factor, psychological factor and behavioral factor to 227 mothers. They had children from 3 to 5 years. The collected data was analyzed by SPSS WIN 12.0. Results : There were statistically significant differences in oral health knowledges as mother's educational background, importance of oral health, experience of oral health education, and oral health locus of control. There were statistically significant differences in mother's oral health care behaviors as mother's job, interest of oral health, importance of oral health, experience of oral health education, and oral health locus of control. And mother' oral health care behavior for herself, interest of oral health, and oral health locus of control were found as important variables in mothers's oral health care behavior for their children. Conclusions : Mother's oral health care behavior for herself was the powerful factor that affected mother's oral health care behavior for her children.

The curriculum differentiation is supposed to maximize individual strength and possibilities of the students, and to maximize educational efficiency by differentiating the instructions according to students' abilities, aptitudes, needs and interests. The Ministry of Education has suggested a stepwise model for school mathematics. This model is named "Stepwise Curriculum Differentiation"(段階別 敎育課程 差別化). In this paper, we would like to make a specific proposal for the 7th curriculum. Our proposal reflects fully the guidelines of the Ministry of Education. It is also based on the national curriculum history up to the present time. It could be used as a reference for the continuing work of curriculum reformation. We suggest dividing the contents of mathematics for 1-10th graders into about 15 steps, to use the step-based textbooks instead of the grade-based ones, and to prepare evaluation standards for each step. We also suggest that the classes for grades 11-12 be organized according to their optional courses and/or their steps.

Outdoor education emphasizes diverse experiences from the internal growth which is expected from the learners, to the ecological and environmental experiences. It is also the needs of this time and reflected in the education system of Korea. However the goal of outdoor education is not well defined and philosophical efforts to clarify it is also not enough. In this respect, we tried to define the goal and investigated professionalism of outdoor education. Specifically, we investigated the professionalism of teachers and instructors of physical education. The goal was investigated in two areas 1) holistic experience and problem solving skill and 2) aiming self-reflective practitioner. The idea was that educators must not aim simple educational efficiencies but have to become self-reflective practitioners through everyday life. The conclusions of this study are firstly, a safety manual is required to avoid possible injuries and to give first aid in an unfortunate occasion, secondly, an education program is required to train outdoor professionals and lastly, outdoor education should not remain in the boundary of formal education but should be included in non-formal education.

The supported bimetallic Co-containing catalysts promoted by the different amount of noble metal (Pd) have been studied in the dry reforming of methane. The activity, selectivity, stability and resistance to the carbon deposition of Co-Pd/$Al_2O_3$ catalysts depend on both the catalyst composition and process conditions. It has been observed that the Co-Pd/$Al_2O_3$ catalysts produce the various oxygenates from $CO_2$ + $CH_4$ at moderate pressures.

The photocatalytic degradation of Mordant Yellow-12 (MY-12) was investigated using a UV-Visible Spectrophotometer and pH meter. The UV-Visible absorbance spectra of the MY-12 contaminated water before and after treatment were presented in figure. The decrease of absorbance occurs at the range of 250 and 450 nm, this result suggests that photocatalytic degradation involves destruction of the aromatic rings in this experiment. More than 32% of the MY-12 was decomposed after one hour in 26-W fluorescent lamp, whereas it was 17% and 24% respectively in 15-W and 21-W lamps. MY-12 was decomposed completely after three hours in 26-W fluorescent lamp. The destruction rate constants were calculated from the change of absorbance and pH.

Objectives : This study is to examine the effectiveness in the oral health promotion through the oral health education for high school students. In adolescence, there seems to be the high incidences of dental caries, gingivitis and periodontal diseases. Concerning preventing all such outbreaks, this study focuses on applying the oral health education to their health education, and on analyzing its effectiveness. Methods : To verify its effectiveness, this research administered 85 students of both genders of a certain high school in Seoul during May-October 2010, followed by the evaluation of DMFT, S-PHP, and CPITN. Results : First, the oral health promotion through the education was statistically significant in the permanent effects of index (FT index). Second, the effect of S-PHP index gradually decreased in statistics from the first to the fifth session, but, after five months ever since the education, it seemed relatively higher in the next sessions. Third, the changing in the level of CPITN decreased continuously as the students received the education repeatedly, but there is no significant difference in statistics for each session. Conclusions : For the oral health promotion in the high school students, the education ought to be focused on the behavior-change objectives rather than on the knowledge-based objectives. The repeated education for tooth-brushing instruction should be stressed for preventing from returning to the old bad behaviors.

Purpose: This study is aimed to map the provinces in Indonesia based on the education and ICT indicators using several unsupervised learning algorithms. Research design, data, and methodology: The education and ICT indicators such as student-teacher ratio, illiteracy rate, net enrolment ratio, internet access, computer ownership, are used. Several approaches to get deeper understanding on provincial strength and weakness based on these indicators are implemented. The approaches are Ensemble K-Mean and Fuzzy C Means clustering. Results: There are at least three clusters observed in Indonesia the education quality, participation, facilities and ICT Access. Cluster with high education quality and ICT access are consist of DKI Jakarta, Yogyakarta, Riau Islands, East Kalimantan and Bali. These provinces show rapid economic growth. Meanwhile the other cluster consisting of six provinces (NTT, West Kalimantan, Central Sulawesi, West Sulawesi, North Maluku, and Papua) are the cluster with lower education quality and ICT development which impact their economic growth. Conclusions: The provinces in Indonesia are clustered into three group based on the education attainment and ICT indicators. Some provinces can directly implement e-learning; however, more provinces need to improve the education quality and facilities as well as the ICT infrastructure before implementing the e-learning.

This study was conducted for researching demand on dietary education of low-level elementary school students and to develop an activity based textbook and a teaching manual on the subject. For necessity of dietary education, 88.8% of subjects answered dietary education is needed. The desirable frequency of the education was once a week (65.7%). The most appropriate time for the education was "school lunch" (37.5%), "special activity" (29.9%), "regular class" (12.4%) and "after school activity" (12.1%). The most preferred educational method was "experiment and practice" (40.1%). The desirable educational materials were "computer materials" (20.7%), "actual objects" (20.1%), "videotapes" (16.5%), "photographs-pictures" (12.2%) and "fairy tales-cartoons" (12.2%). The students wanted dietary information as "cooking" (26.1%), "growth and nutrition" (23.7%) and "right food information" (20.1%). The textbook was composed of five major chapters, which were "Traditional Dietary Culture", "Food", "Dietary Habit", "Hygiene and Environment" and "Cooking". Each major chapter had five to six smaller chapters, adding up to total of 32 chapters. The textbook had fun characters, illustrations, photographs and cartoons to deliver the main theme of each chapter. The textbook was in activity format so that it coul be readily and directly used in actual classes. The teaching manual was composed of background, goals, teaching plans and teaching points. The smaller chapters had learning goals, teaching-learning resources, important points, teaching-learning processes and reference materials. Videos were produced to help cook five snacks in the cooking chapter. Also, "Healthy Song" was created to be used in classrooms. This textbook will be helpful in children's right dietary habits and growth.
