In this paper, we propose a blood pressure measurement method using ANFIS. Usually, the maximum and minimum blood pressures are calculated by Maximum Amplitude Algorithm(MAA) method. However, the MAA method has some drawbacks to measure exact blood pressure since it uses a fixed ratio to set the measuring points for everyone without considering individual's special conditions. To solve this problem, the pressures measured by the MMA are trained by ANFIS having self-learning ability. From various experiments, we confirm that the proposed method shows better performance than conventional method.

According to Krutetskii, the education of mathematically gifted students must be focused on the improvement of creative mathematical ability and the mathematically gifted students need to experience the research process like mathematician. Independent study is highly encouraged as the self-directed activity of highest level in the learning process which is similar to research process used by experts. We conducted independent study as a viable differentiation technique for gifted middle school students in the 3rd grade, which participated in mentorship program for 10 months. Based on the data through the research process, interview with a study participant and his parents, and his blog, we analyzed mathematical behavior characteristics of a study participant. This behavior characteristics are not found in all mathematically gifted students. But through this case study, we understand mathematically gifted students better and furthermore obtain the message for the selection and education of the mathematically gifted students and for the effective method of running mentorship program particularly.

This study was conducted to develop a nutrition education workbook to improve picky eating in children and to evaluate the effect of nutrition education using this developed workbook. The developed workbook focused on 2nd and 3rd grade students and consisted of five units. The contents included: multi-grain, vegetables (2 units), fish, and milk. The activities, including observation, and learning the roles and names of the foods, were developed mainly to increase motivation for eating a balanced diet. This workbook was developed from April to December 2008, and was applied at 15 elementary schools containing 1,674 students from April to September 2009 in Changwon City, Korea. We evaluated changes in knowledge before and after education on nutrition, eating behavior, dietary habits, and educational activities using self-administered questionnaires. The children demonstrated significant improvements in nutritional knowledge (P<0.001), eating behavior (P<0.001), and dietary habits (P<0.001). Most of the children answered that the education program was helpful and exciting. Based on these results, we believe that the developed workbook is suitable for children picky eaters, and hope it will be used in the field of child nutrition education.

This study aims to examine how motivational constructs are interrelated with social, context-specific factors and, as a result, contribute to L2 writing achievement within the framework of self-determination theory. The data consisted of 67 Korean college students' questionnaire responses, final scores in an on-offline blended writing course, and qualitative interviews with 5 students. In the descriptive and the correlation analyses, the participants' extrinsic motivation was found higher than intrinsic motivation, with low amotivation. Among social factors, immersion environment, foreign instructor, and peer comparison marked high scores, whereas Korean instructor and online material gained low scores. Those contextual factors were interrelated with each other, such that the immersion factor correlated significantly with Korean instructor and peer comparison. Extrinsic and intrinsic motivational subscales engendered strong correlations with the high-scored social factors, i.e., immersion, foreign instructor, and peer comparison, which were also closely interrelated with L2 writing achievement. The findings illuminate intricate workings of motivation in its effects on L2 achievement and corroborate the roles of contextual factors. The effect of motivational subscales on achievement may be valid through interplay with some social factors. The dynamics of motivation is discussed for pedagogical applications.

This study was to explore the living experiences of the disabled adults who were participating in public education Yahak program held at evening class. The study designed in-depth interviews with ten disabled people using a grounded theory approach. Through analyzing process, 34 concepts, 15 subcategories, and eight categories were deduced. In axial coding, casual condition, 'Suffering from unknown cause disabilities' and 'Isolated by social cause', context condition, 'Taking discriminative treat for disabilities' impacted on phenomenon, 'Overcoming their conditions by themselves'. Intervening conditions was 'Taking social supports' and action-interaction condition, 'Enjoying public programs' totally lead to consequence in 'Controlling daily life' and 'Exploring their own social roles'. The periods of process were divided three stages, reflecting disabled situation, formation phase of social relation, and self-developing phase. The core category, 'Trying to be recognized as a member of society' incorporated the relationship between and among all categories and explained the process. The study indicates that social education program for the disabled helped to develop themselves as a member of society. Therefore, we suggest there may be a need for training for professionals who work with disabled people to develop social adaptation.
