  • Purpose: This study was conducted to investigate quality of life according to social support of elderly in the rural area. Method: The subjects of this study were 199 people aged over 60 who had been living in three rural areas. Date was collected through questionnaires from July 10th, to August 10th, 2003. Result: The most socially supportive people they answered were friends(80.9%), followed by children(74.9%), neighbors(71.9%), siblings(55.8%), spouse(53.3%), in descending order. Mean social support score for spouse was 13.36, for children 13.27, for friends 11.40, for neighbors 10.21, for siblings 10.20. A comparison of the average grade points per items according to the offerers of social support revealed spouse support(13.36 out of 18), children support(13.27), friends support(11.40), neighbor support(10.21), siblings support(10.20). The average of the quality of life score was 132.26 out of 220. A comparison of the average grade points per items within sub-areas of quality of life revealed the highest score of neighbor relationships(4.29 out of 5.00) and the lowest score of economic conditions (2.61) Quality of life scores correlated positively with social support scores(r=.734, p<.001). Variables significantly influencing quality of life were spouse support(36.1%), neighbor support (5.1%), age(2.2%), religion(1.7%). These variables explained 45.1% of the variance in quality of life. Conclusion: Social support for elderly people in rural areas identified this as a greatly effective factor for their quality of life. Therefore, it is necessary to develop health promotion programs connected with social support in order to enhance the quality of elderly people in rural areas.

  • As the size of containership increased over 14,000TEU, thick steel plate with high strength has been used. The plate thickness increased over 70mm and yield strength of the steel plate was around $47kg_f/mm^2$. Many researchers reported that the thick welded plate has low crack arrest toughness. They noticed the crack arrest ability is dependent on the plate thickness. In other words, brittle crack propagates straightly along the welded line and make abrupt fracture in the thick plate which causes low $K_{ca}$. In this study, the other factors, especially welding heat input, to cause low crack arrest toughness was investigated for thick steel plate welds. EH grade steel plates were used in this study and 50 to 80 thick plates were tested to confirm thickness sensitivity. Electro gas welding (EGW) and flux cored arc welding (FCAW) were adopted to prepare the welded joints. Temperature gradient ESSO test was performed to measure $K_{ca}$ values with the variation of welding variables. As a result of this study, regardless of plate thickness, welding heat input to cause welding residual stress around crack path is a key factor to control the brittle crack propagation in welded joints.

  • The aim of the National Assessment of Educational Achievement (NAEA) is to produce specific and reliable resources required for the diagnosis and quality control of teaching and learning by measuring the level of students achievement based on the national curriculum. In 2002, we introduced ‘modified Angoff Method’ to obtain more systematic and rational results about the achievement levels. The result indicated the differences of achievement level according to the differences of sexes. Female students achieved higher scores than male students in Grade 6. Male students achieved higher scores than female students in Grade 9 and 10. Furthermore it disclosed a problematic phenomenon that students in small towns and rural areas showed significantly lower scores in all six sub-areas of Mathematics compared with students in metropolitan and cities. The results from the NAEA listed above could be used as the authentic data for improving national curriculum and teaching and learning methods, the establishment of educational policies, and many other areas.

  • The purpose of this study is to find out the effect of hypothesis formulations using abduction on science processing skills and the creative thinking activities. As the subject, 2 classes in the $6^{th}$ grade of B elementary school located in Busan were selected. Through the pre/post inspection design between experiment and comparison class, the units of science courses in the second semester of $6^{th}$ grade '1. A change in the weather' and '2. Various gases' were applied. The results were as follows: Firstly, the test on science processing skills showed that there was not statistic meaningful differences between the two groups. And, in the sub-parts, there was not statistic meaningful differences between the two groups. Secondly, it was observed that it would have a meaningful effect to improve the creative thinking activities of students who performed hypothesis formulation using abduction. Especially, through this, the experimental class gave a positive effect on the 'Fluency' and 'Elaboration', one of lower categories of the creative activities. The results of 'Flexibility' and 'Originality' in the experimental class were higher than those of students in the comparative class. However, according to statistical analysis, this result is meaningless. Thirdly, on the survey about the hypothesis formulation using abduction, many students thought that this learning method was very interesting and helpful to study science. In addition, it was observed that the ability to use abduct thinking was improved more than ever before.

  • Environmental education as worldwide sustainable education is effective when it is carried out as early as possible. But we do not have any aims and textbooks for environmental education in the elementary school. The purpose of this study is systematizing environmental syllabus as sustainable education. To achieve this purpose, firstly, the meaning of environmental education as sustainable education was conceptualized, secondly, the aims of environmental education was set up, thirdly, domains of environmental education was revised, and lastly, the syllabus for environmental instruction were created for each grade. Literature review was practiced over 143 textbooks and teacher's guidebooks from the 4th to 7th curriculum period. The result of this study follows. First, environmental education as sustainable education in the elementary school was conceptualized as an integrative education to keep the lifelong education and welfare. Second, the synthetic aim of environmental education as sustainable education in the elementary school was set up as 'cultivating desirable environmental people that behave for the sustainable future with environment-friendly value and attitude. Third, our environmental domains were divided into 11-12 independent areas, and ESSD (Environmentally Sound and Sustainable Development) was located on the subcategory of environmental domain. These domains were revised into three environmental domains and five sub-domains. Fourth, according to the aims of environmental education as sustainable education and five environmental domains, 253 objectives were established. Fifth, objectives of environmental education of 10 subject matters and integrative objectives were presented. Sixth, based on the objectives of domains and subject matters, 255 contents for environmental education in the elementary school were abstracted and distributed to each grade in the consideration of balance among domains and appropriateness of grades. Seventh, analytic results of textbooks of 7th curriculum shows heavy stress on the 'knowledge perception' section and deficiency on the altitudes and behavior section. The environment-related level and contents overlapped and fragmented deeply. Furthermore, 33 parts of textbooks could bring to mis-concept on environment.

  • The purpose of the study was to find the effect of play-using assertion training program on elementary school children's self-expression, interpersonal relationship and self-efficacy. For the purpose of the study, the researcher sets hypotheses as follows. Hypothesis I : The play-using assertion training program has significant effect in elementary school children's self-expression. Hypothesis II : The play-using assertion training program has significant effect on elementary school children's interpersonal relationship. Hypothesis III: The play-using assertion training program has significant effect on elementary school children's self-efficacy. To verify these hypotheses, the researcher selected 10 students of 4th grade in C elementary school as a experimental group, and 11 students of 4th grade in O elementary school as a controlled group. Both schools are located at Boryoung, Chungnam. In the experimental group, the researcher administered the play-using assertion training program once a week for ten weeks. The play-using assertion training program are made by the researcher based on Jeon(1985) and Byoun and Kim(1980). To measure self-expression, the scale of self-expression made by Byoun & Kim(1980) was used. To measure interpersonal relationship, the scale of relationship change made by Schlin and Guerney(1971) was used. The scale was translated by Lee and Moon(1980). To measure self-efficacy, the scale of self-efficacy made by Han(2002) was used. The scale is based on Kim and Cha(1996) and Kim(1997). The result of the study is that the play-using assertion training program gives positive effects on students' self-expression, especially in physical area. Second, the play-using assertion training program gives positive effects on students' interpersonal relationship, especially in satisfaction, communication and friendliness. Third, the play-using assertion training program generally does not give positive effects on students' self-efficacy, but give significant effects on confidence and self-control efficacy which are sub-areas of self-efficacy.

  • Numerical research on four typical configurations of noise mitigation structures and their characteristics of wind loads are reported in this paper. The turbulence model as well the model parameters, the modeling of the equilibrium atmospheric boundary layer, the mesh discretization etc., were carefully considered in the numerical model to improve the numerical accuracy. Also a numerical validation of one configuration with the wind tunnel test data was made. Through detailed analyses of the wind load characteristics with the inclined part and the wind incidence angle, it was found that the addition of an inclined part to a noise mitigation structure at-grade would affect the mean nett pressure coefficients on the vertical part, and that the extent of this effect depends on the length of the inclined part itself. The magnitudes of the mean nett pressure coefficients for both the vertical part and the inclined part of noise mitigation structure at-grade tended to increase with length of inclined part. Finally, a comparison with the wind load code British/European Standard BS EN 1991-1-4:2005 was made and the envelope of the mean nett pressure coefficients of the noise mitigation structures was given for design purposes. The current research should be helpful to improve current wind codes by providing more reasonable wind pressure coefficients for different configurations of noise mitigation structures.
