In this study, instruments were developed to measure of mathematics attitudes by conceptualization of epistemological beliefs as a cognitive dimension, mindfulness as a conative dimension, affect as an affective dimension. Perry's epistemological development scheme and Langer's mindfulness theory was noticed as a theoretical approach. Exploratory factor and confirmatory factor analyses, and a reliability test were assessed. This article suggest a new framework for analysing attitudes toward mathematics and changes in attitudes toward mathematics.

We attempted to find the style of flower arrangement from the drawings of Uigwe and paintings of folding screens for the royal ceremonies of the late Joseon dynasty. In the pictures of the Uigwe and folding screens, we could see the linear, circular, and oval types Junhwa used to decorate the left and right sides of the throne placed in the center of main parish at the national banquet. There were also identified the Sanghwa which was used to decorate food on it, Jamhwa which was used to decorate head to be worn on the caps or hats, and Hwaga which was used to decorate the style supporting the large awnings at the national banquet. Hwaga was found, in the Musin Jinchan Dobyeong. In 1795, it was found that decorations on the floor, which are quite similar to the table decorations and modern space decorations, and flower shoot presented by king and flower decorations which were bound to the stick which was presented by king to country old men from Wonhaeng Eulmyo Jeongri Uigwe and Hwaseong Reunghaengdobyeong

We need to reflect the establishment of meaning and level of 'proof and argumentation in middle school mathematics'. It should be considered as human activity through communication in community. Thus, we should design instruction from this standpoint. From this point of view, we had been operated 'Geometry Inquiry Class' aimed at middle school students in eighth grade for two years to improve current geometry class in middle school. In this study, we will observe how individual students' original proof schemes are developed and accepted to the class through the process of mutual negotiation between the teacher and students. The episode with four phases begins with the initial proof schemes students have offered. Through the negotiation of class participants, it gives birth to the proof scheme unique to the current geometry classroom. Why do we pay attention to the process? It is because we think that the value of this type of instruction lies in the process of communication and mutual understanding and mutual reference, not in the completeness of the final product. This is the very appropriate proof in the middle school mathematics classroom.

The formula was proposed through the examination of probability rainfall intensity formula used in Incheon based upon recent occurrences of heavy rain and extraordinary storms. Random-time maximum annual rainfalls were estimated for durations from ten minutes to twenty-four hours from the data by Korea Meteorological Administration. Eleven types of probability distribution are considered to estimate probable rainfall depths for different storm durations at Incheon city. Three goodness-of-fit tests including Chi-square, Kolmogorov-Smirmov and framer Von Misses were used to analyze the tendency of recent rainfall. Considering maximum rainfall occurred, General Extreme Value(GEV) distribution was chosen as the appropriate probability distribution. Five types of probability rainfall formulas including Talbot type, Sherman type, Japanese type, unified type I and unified type II are considered to determine the best type for rainfall intensity at Incheon. The formula was determined considering the time of concentration of sewer system and river at Incheon city. Unified type I was chosen for its accuracy and was proposed to represent rainfall intensity of Incheon district.

Objective : Purpose of this study is to study how Sensory Integration (SI) Intervention Program affect body-scheme and praxis ability of children with Developmental Disability (DD). Method : The SI intervention was programmed based on the theory of SI by Jean Ayres. Thirty children with DD underwent the SI program for six weeks. The effect of the SI intervention was evaluated in terms of body-scheme and praxis ability. Assessments used in this study are One-Point Imitation Test (OPIT) and 6 Body Puzzle Test (6BPT) for body-scheme; Praxis Test Sheet (PTS) for linguistic order, oral motor control, sequential praxis and Sensory Integration and Praxis Tests (SIPT) for postural praxis. Data of this study was analyzed by the paired t-test to compare before- and after the SI intervention. Results : Results of this study are (1) in the OPIT, there is significant difference on body-scheme ability (p<0.01); (2) in the PTS, there is significant difference on all three items (p<0.01); and (3) in the SIPT, there is significant difference on sensory integration and praxis function. Conclusions : From the results, it is concluded that sensory integration intervention is effective on body-scheme and praxis functions for children with developmental disability.
