The purpose of this study is to analyze the differences between the cognitive load of mathematics textbooks based on storytelling and traditional mathematics textbooks that are presented to students. In order to verify this, we have selected two 4th grade classes in elementary school that were identified as a homogeneous group through prior testing, and thus were separated into experimental group and comparative group. Then, without the teacher's lessons, the experimental group learned from mathematics textbooks based on storytelling and the comparative group learned from traditional mathematics textbooks. Afterwards, the two groups' cognitive load was measured through a questionnaire, and the following results were obtained: In the 'mental effort' and 'self evaluation' categories, the students that learned from the mathematics textbook based on storytelling showed higher scores than the students that learned from the traditional mathematics textbook. also there was statistically significant difference in some items. However, no statistically significant difference was found in the remaining categories 'task difficulty', 'self evaluation', and 'material design'.

The purpose of this study is to analyze longitudinal trends of students' mathematical affective domain by use of the data mining method. For this purpose, we used the Korea education longitudinal study(KELS 2005) which was the survey data for students' achievement test, affective domain test, teachers' evaluation, and parents' evaluation from $7^{th}$ grader in the year of 2005 to $11^{th}$ grader in the year of 2010. Subjects of this study is a total of 5040 students who answered to the mathematical affective domain survey in KELS 2005. The result findings are as follows. First, students' affective domain had changed negatively as they went up to higher grade. Second, if students' affective domain had built at a certain level in $7^{th}$ grade, the level did not change easily until $11^{th}$ grade. Third, major factors of students' affective domain were shown to be self-efficacy, intrinsic motivation, efforts and patient, and time management.

This paper demonstrates the possibility of evaluating the safety of a building right after an earthquake using consumer-grade surveillance cameras installed in the building. Two cameras are used in each story to extract the time history of interstory drift during the earthquake based on camera calibration, stereo triangulation, and image template matching techniques. The interstory drift of several markers on the rigid floor are used to estimate the motion of the geometric center using the least square approach, then the horizontal interstory drift of any location on the floor can be estimated. A shaking table collapse test of a steel building was conducted to verify the proposed approach. The results indicate that the accuracy of the interstory drift measured by the cameras is high enough to estimate the damage state of the building based on the fragility curve of the interstory drift ratio. On the other hand, the interstory drift measured by an accelerometer tends to underestimate the damage state when residual interstory drift occurs because the low frequency content of the displacement signal is eliminated when high-pass filtering is employed for baseline correction.

The purpose of this study was to investigate the evaluation of regional antagonism in children and adolescents in Youngnam and Honam region. There were 684 subjects included in this study from three ages in the Youngnam and Honam regions: 12.8 years(6th grade, n=208), 14.8 years(8th grade, n=211), and 16.9 years(10th grade, n=265). Of the 684 subject, 357(53.3%) were boys and 327(47.8%) were girls. The instruments consisted of subjects' self-reported social distance, stereotype, and prejudice. The data were analyzed by frequencies, t-test, one-way ANOVA and the $Scheff\'{e}$ test. Major findings were as follows: The mean score of the out-group stereotype was greater than the median, so the in-group preference was greater than the out-group exclusion. The in-group stereotype was different based on the age and the sex. The 6th and 8th graders and the boys were higher than 10th and the girls. The prejudice was different based on the lesion. The social distance was different based on the age and the region.

As a cross-sectional study, this study was aimed to investigate and compare the job efficiency and satisfaction of nurses according to the hospital grade. Survey was conducted by mail on June 2009, and the respondents were 1,016 nurses working in 15 hospitals which are 9 high-grade general hospitals and 6 general hospitals. The percent of nurses acknowledging their hospital grades is 34.5%, and that is 20.5% at high-grade general hospitals. As the result of review of studies, it is concluded that under the circumstance that differential rates are contracted to calculate fees for hospital services and copayment of patients are according to nursing grades and hospital grades, the degree of nurses' awareness of insurance fees impact on their performance like recording of care and prescription. In order to improve nurses' performance, they need to be educated about the national insurance fee system. In hospitals with higher nursing grade and more beds, the levels of nursing quality and faithfulnes and their job satisfaction were higher. Nurses' awareness of their hospital nursing grade was related to the quality of nursing but not the faithfulness. Nurses working in higher nursing-grade hospital are more self-respect and satisfied at their jobs, and their job efficiencies are not significantly different. The current nursing fees based on the proper number of nurses per beds of nursing units should be changed to be based on the amount of job per nurse by their nursing protocol, and the nurse staffing standard should be differentiated between nursing grades. As the aspect of nursing, 24-hours patient care, it is difficult to improve nurses' job satisfaction, and in the other hand, that tends to depend on their income level. In the current circumstance, comprehensive research is required to investigate the propriety of 25% of the inpatient fees as the nursing management charge.

The purpose of this study is to guide and apply gettable and accessible materials around everyday life into classroom instruction, and to find out their effects on student academic achievement. In order to achieve it, this study was tried to develop and guide available materials around life in teaming activities, to provide a preliminary assignment that could apply the available materials, and to compare its academic achievement to one from field trip loaming. For the hypothesis testing, first, the experimental and comparing classes were selected based on the results of basic learning diagnostic evaluation, which conducted by the researcher being served as a full-time science teacher of the third and sixth grade of K elementary school in Kwangju for 2 years. Secondly, the instructional use of the available materials around life was applied to the experimental class. Also, the instructional use of the existing materials was applied to the comparing class. Finally, for the testing of the effects on academic achievement, the posterio test was implemented after conducting the experimental instruction in knowledge·understanding, inquiry process, and attitude domains classified by the unit characteristics. Using SPSS/WIN program the t-test was performed in order to compare the differences between the two groups. Major findings were as follows: 1) In the achievement test of knowledge·understanding domain, there were no significant differences at the 5％ level between the experimental and comparing classes. It could be difficult to say, therefore, that the instructional use of the available materials around life was more effective than the instructional use of the existing materials. However, it had some effects on differences between the third grade final achievement test and sixth grade experimental class. 2) In the achievement test of inquiry process domain, there were some significant differences in that the sixth grade experimental class was higher than the third grade out-of classroom experience unit. It was indicated that the instructional use of the available materials around life had some effects on improving the students' inquiry ability 3) In achievement test of attitude domain, there were some significant differences. It was shown that the self-evaluation test of the sixth grade experimental class unit was higher than that of the third grade out-of classroom experience unit; Especially, the learning activities in the experimental class were more active, and the experimental practice ability was improved. It was presented that the instructional use of the available materials around life had some effects on the students' academic achievement in attitude domain. It was concluded from this study that the instructional use of the available materials around life was less effective on Knowledge understanding domain, but was effective on improving their scientific inquiry ability and interest on science education.

In the case of cardiac failure, it is to make its basic data and develop its education program of CPR(cardiopulmonary resuscitation) which can increase the patient's survival rate before his hospitalization. The findings of this study is as follows. The subject of study is composed of 117 persons who are 54 boy-students(46.2%) and 63 girl-students(53.8%) in sex and 72 first-grade students(61.5%) and 45 second-grade students (38.5%) in a school year. In the accuracy degree, the practice of artificial respiration is $42.28{\pm}34.42%$ in case of basic CPR(cardiopulmonary resuscitation). The accuracy degree of the thorax pressure is $82.17{\pm}15.40%.$ In the accuracy degree, the practice of artificial respiration is $92.16{\pm}25.68%$ in boy-students and $20.38{\pm}24.16%$ in girl-students, the second-grade students is $58.40{\pm}33.29%$, which is higher than the first-grade students' $32.21{\pm}31.14%$. In the accuracy degree, the thorax pressure is $92.16{\pm}3.91%$ in boy-studetns and $73.61{\pm}16.41%$ in girl-students. In the accuracy degree of the thorax pressure, the second-grade students are $82.60{\pm}16.54%$ and the first-grade students $81.91{\pm}3.91$, which doesn't show any significant difference in school year. The satisfaction degree after theory & practice education is $2.12{\pm}.85$. In the satisfaction degree of its basic CPR, girl-students are $2.14{\pm}.83$ and boy-students are 2.11. In the satisfaction degree of its basic CPR, the second-grade students are $2.40{\pm}.61$ and the first-grade students are $1.95{\pm}.94$. This study is to lead to some suggestions. First, it is necessary to develop the education program and educate its knowledge & technology in proportion to student's characteristics of sex and school year. Second, education authorities should develop a subject of the accident prevention and first-aid treatment in its curriculum and provide the practical education of CPR for adults, adolescents and children. Third, it is necessary to study the education program as well as the education evaluation of CPR further on.
