The purpose of this study was to investigate the effects of estimation strategy on placing decimal point in multiplication and division of decimals. To examine the effects of improving calculation ability and reducing decimal point errors with this estimation strategy, the experimental research on operation with decimal was conducted. The operation group conducted the decimal point estimation strategy for operating decimal fractions, whereas the control group used the traditional method with the same test paper. The results obtained in this research are as follows; First, the estimation strategy with understanding a basic meaning of decimals was much more effective in calculation improvement than the algorithm study with repeated calculations. Second, the mathematical problem solving ability - including the whole procedure for solving the mathematical question - had no effects since the decimal point estimation strategy is normally performed after finishing problem solving strategy. Third, the estimation strategy showed positive effects on the calculation ability. Th Memorizing algorithm doesn't last long to the students, but the estimation strategy based on the concept and the position of decimal fraction affects continually to the students. Finally, the estimation strategy assisted the students in understanding the connection of the position of decimal points in the product with that in the multiplicand or the multiplier. Moreover, this strategy suggested to the students that there was relation between the placing decimal point of the quotient and that of the dividend.

Background : There have been many studies and efforts about quality management in health services, but these were not focused on the thinking ability of the personnel. In this study, We planned to define the relationship between Quality Management(QM) and thinking skill, and analyzed critical thinking skill and problem solving ability of the nurses for QM in healthcare. Methods : We surveyed 260 nurses in 3 hospitals by using questionnaires about thinking skills and QM from November 18 to 28, 1998. The response rate was 76.9%. We described and analyzed the data by descriptive statistics, t-test, ANOVA, Pearson correlation, and non-parametric Friedman test using SPSS Win 7.5. Results : This study revealed that 1) understanding level of QM concepts was very low and insufficient, 2) willingness to practice QM in healthcare was relatively high and affirmative, but the positive attitude taking part in the program of QM is very low(4.5%), 3) even though the necessity of QM was recognized, actual application of critical thinking skills and problem solving abilities is lacking, 4) the production of idea for QM was the most insufficient, and so the next of the problem solving process(QA cycle) was the same. Conclusion : Based on the above results, we can conclude that understanding the concepts of QM is very important to solve problems about QM in healthcare. For development of thinking skill to promote critical problem solving ability for QM in healthcare, it is necessary to improve curriculum of nursing education and teaching-learning methods of QM strategy and technique.

The purposes of the study were to investigate whether the use of the Geometer's Sketchpad(GSP) is more effective than the use of traditional tools such as ruler and protractor to enhance eighth- grade students' understanding of quadrilaterals and geometric reasoning ability and to examine how the use of the software affects on the development of students' understanding and reasoning ability. According to the results of the posttest, there was a significant difference in student achievement between students using GSP and students using ruler and protractor. Students using GSP significantly outperformed students using ruler and protractor on the posttest. Student interview data showed that the use of the GSP was more effective in developing students' geometric reasoning ability. Students using GSP achieved higher degrees of acquisition for van Hiele level 2 and 3 than students using ruler and protractor. Dynamic visual representations and hands-on experiences provided in GSP learning environment helped students approach quadrilateral concepts more conceptually and realize their pre-existing conceptual errors and re-conceptualize their mathematical ideas.

Method: The subjects in this study were 56 juniors who were majoring in nursing science at H and S college in Chungnam province. At each college, an experimental group and a control group were organized with 26 and 30 students respectively, and the data were gathered at H college from April 6 through May 14, 2004, and at S college from May 31 through July 3, 2004. A MBTI based self growth program was conducted 10 times for five weeks, twice a week and for 120 minutes each. And the ego identity, self efficacy, interpersonal relations ability and adjustment of the selected students were measured and compared to see if that program has any effect on above variables. For data handling, SAS 8.0 program was employed. Fisher's exact test and unpaired t-test were used to confirm whether or not the experimental and control groups were equivalent. Before the experiment, their ego identity, self efficacy, interpersonal relations ability and adjustment were tested by one-way ANOVA and Scheffe's multiple comparison in consideration of their general characteristics, and paired t-test and ANCOVA were utilized to see if that program brought any changes to their ego identity, self efficacy, interpersonal relations ability and adjustments. Result: The findings of the study were as follows; After the MBTI based self growth program was applied, the experimental groups made a significant progress in ego identity than the control groups. And the experimental groups underwent a significantly change in ego identity after the experiment, compared to the control groups. The experimental groups showed a significant improvement in self efficacy than the control group, and the experimental groups showed significant change in self efficacy than the control groups after the experiment. The experimental group showed a significant progress in interpersonal relations ability than the control group did, and the former groups underwent significant change in that regard than the control groups after the experiment. There was no difference in adjustment between the experimental and control groups. The experimental groups showed significant change in adjustment than the control groups after the experiment, but the difference was insignificant. After this program was implemented, the students underwent changes in self understanding, self accepting, understanding others and accepting others. They also had more confidence and more positive self images, and they were better able to tide over difficulties with others. Conclusion: The results of this study suggested that the MBTI based self growth program might serve to enhance the ego identity, self efficacy and interpersonal relations ability of the nursing students and brought inner changes to them. Therefore, the MBTI based self growth program was expected to make a great contribution to the character building of nurses.

This paper is to develop an integrate curriculum of rhythm education activity program and to find the possibility of applying the program into actual music education field for kindergarten children. The outlook of this study is to develope a program integrating the elements of movement, language and rhythm to apply the program to 5 year old children for 6 weeks through 12 sessions, and to observe and analyze their level of rhythm creativity and rhythm reading ability.The analysis of the field observation data and recording data showed that the children achieved natural and better understanding of rhythm. Seen from the perspective of rhythm creation activity, while the integration of the elements of movement and rhythm influenced directly to enhance the level of understanding rhythm and the integration of the elements of language, rhythm helped indirectly to have better understanding rhythm through connecting the notions of rhythm and movements. However, when only rhythm and movements were combined, children tended to misunderstand the relative durations of ♩ and ♪ just as different tempos not as 2:1 duration relativity. And ♫ was too misunderstand as ♬ due to different durations of korean words when only rhythm and language were combined. To overcome the limit of understanding, all of the three elements; rhythm and movements and language should be integrated and constant auditory experiences are recommended.
