This study reviewed elementary school teachers' opinions on the integrated curriculum in terms of the 2007 curriculum draft revision, as well as surveying their requests in regards to the 2009 curriculum draft revision. This study was conducted by means of questionnaires with 183 elementary school teachers. Most agreed that a theme-based-integrated curriculum was better than studying separate subjects, but most also argued that it takes considerable time reorganize and implement the integrated curriculum. Successful implementation also requires further teachers' training and their cooperation. The theme-based texts have already been in use from 2009 for first and second grades. Teachers prefer training courses which focus on the integration of the subjects, understanding the nature of each subject and sharing ideas and tips. Such training can assist in identifying the gaps between the curriculum plans and real classroom applications. Furthermore it can present clear guidelines to help ensure that the curriculum is organized effectively and well managed. Networks of specialized personnel or programs were also found to be very good resources both in and out of school.

The purpose of this study is to investigate the differences of early childhood teachers' job satisfaction and burnout by variables and to analyze the relationship between the two subject matters. Then this study will serve to improve overall quality of early childhood education through fair comprehension about them. We surveyed 333 teachers in total, 171 public/private kindergarten teachers and 162 preschool teachers. A questionnaire by ECJSS of Jord-Bloom(1989) and Fleischer(1985) was used to measure the degree of job satisfaction, along with the version MBI(Maslach Burnout Inventory) by Maslach and Jackson(1981), adjusted by An, youngkil(I992) and Seo, jiyoung(2002), to check the degree of burnout. It was found that job satisfaction was higher among the surveyees of old age or with more education/less working hours. Small salaries, however, was one of the causes of low job satisfaction. Emotional burnout was shown in the surveyees of old age or with good education/career records. On the other hand, exhaustion from a lack of accomplishment was shown in single, young and low paid teachers. Thus, burnout and job satisfaction had a highly negative coefficient of correlation, meaning that job satisfaction gets high when burnout gets low.

Purpose： This study compared lifestyles of middle school students with and without atopic dermatitis in order to obtain the baseline information for health education. Methods： This study involved 256 students from 20 middle schools in Busan who suffered from atopic dermatitis and 231 students from 2 middle schools in Busan who did not have atopic dermatitis. Results： Students with atopic dermatitis had a lower family income (탑=16.99, p<.001) and were more likely to come from a nuclear family (탑=10.28, p<.001) than control students. 98% of the students with atopic dermatitis had several skin symptoms. 78.5% of students with atopic dermatitis reported experiencing difficulties in their daily because of their condition. Students with atopic dermatitis took shorter baths and used soap less frequently than the students in the control group. The students with atopic dermatitis cleaned their houses and bedclothes more often than normal students in an attempt to remove cockroaches and house-dust mites. Students with atopic dermatitis also ate fast and instant foods more often than normal students. Conclusions： Some lifestyle differences exist between students with and without atopic dermatitis. Therefore, education and guidance may be important to promote good health and improve lifestyle quality.

The current panels for liquid crystal display (LCD) TV sets are all characterized by pins placed on two sides. To manufacture one type of panel, a dedicated mask is needed, and the production line should be started once. Moreover, the whole panel needs to be removed if a dead pixel is found. If the panel, however, will first be fabricated with pins placed on four sides and then divided by a cross-cut into four equal-sized panels with pins placed on two sides, one set of masks can be used to manufacture two types of LCD panels, which was referred to by the authors as dual mode. In this paper, the concept of the dual mode and its differences from the conventional way of producing panels are introduced. Its advantages in boosting production efficiency, improving the product's good rate, and lowering the production cost are also described based on case studies. Of particular importance is the fact that the dual mode is very suitable for the trial production of very-large-area LCD TV sets.

This study was conducted to investigate food habits and eating behavior of preschool children. Food habit, eating behavior and health status were investigated by using a questionnaire answered by the mothers of 312 children aged 6 to 7 years old who lived in Uiwang. The average height, weight, Kaup index were 115.08cm, 21.41 kg, 16.13, respectively, for boys 111.37 cm, 19.93 kg, 15.72 for girls. Results showed that 72.16% of subjects skipped the breakfast meal. One of the main reason fur skipping breakfast was 'no appetite'(53.14%). It was found that 49.67% of the subjects belonged to 'good' in health status. The eating behavior of 'watching TV or playing a toy during meal' and 'can eat the rice by oneself were significantly higher score in girls than in boys(p<0.05). Food attention of the parents for the health of children was the highest in 'keep regular meals a day'(92.65%). Health status showed significantly negative correlations with kaup index and eating behavio(p<0.001). Kaup index(p<0.05) and health attention(p<0.001) were positively related with eating behavior. Based on this study, nutritional education program for preschool children would be required for the dietetics teacher to guide the children and more attention should be paid to the nutritional education of food habits in this age group and their mothers.

Link-to-column connections in Eccentrically Braced Frames (EBFs) have critical role in their safety and seismic performance. Accordingly, in this study, contribution of supplemental stiffeners on hysteretic behavior of the link-to-column connection is investigated. Considered stiffeners are placed on both sides and parallel to the link web between the column face and the first stiffener of the link. Hysteretic behaviors of the link beams with supplemental stiffeners are numerically investigated using a pre-validated numerical model in ANSYS. It turned out that supplemental stiffeners can change energy dissipation mechanism of intermediate links from shear-flexure to shear. Both rectangular and trapezoidal supplemental stiffeners are studied. Moreover, optimal placement of the supplemental stiffeners is also investigated. Obtained results indicate a discrepancy of less than 9% in maximum link shear of the numerical and experimental specimens. This indicates that the numerical results are in good agreement with those obtained from the test. Trapezoidal supplemental stiffeners improve rotational capacity of the link. Moreover, use of two supplemental stiffeners at both ends of the link can more effectively improve hysteretic behavior of intermediate links. Supplemental stiffeners would also alleviate the imposed demands on the connections. This latter feature is more pronounced in the case of two supplemental stiffeners at both ends of the link.

The aim of this study focused on student-centered learning not teacher-centered teaching in middle school math classes. This study was performed to check the growth of students' problem-solving abilities, learning attitudes and changes in learning motivation among affective characteristics. The results of this study is as followings: 1) The controlled group a heterogeneous group which had classes in a math room, had more meaningful growth than the uncontrolled group. The results of the study show that the problem-solving abilities of the high-leveled group were better than those of the low-leveled group. 2) The controlled group has shown meaningful difference in their mean in learning aptitude test and attitude test converted their score into 100 points than uncontrolled group, and various kinds of learning materials suitable for problem solving are proved as a good learning factor to induce students' motivation and interest. 3) Students prefer to have classes in a math room to the small-sized and large-numbered classrooms. The atmosphere in a math room is more suitable to improving their problem-solving abilities. In this context, the classes performed in a math room are fairly positive. Consequently, students' leveled learning activities performed in a math room can get their learning motivation and attention from those who are lack of interest and think math is difficult and be effective to increase their problem-solving abilities as a learning method for acquiring the whole course of solving the problems.
