Multiple objective programming has been a popular research area since 1970. The pervasiveness of multiple objective in decision problems have led to explosive growth during the 1980's. Several approaches (interactive methods, feasible direction methods, criterion weight space methods, Lagrange multiplies methods, etc) have been developed for solving decision problems having multiple objectives. However there are still many mathematically challengings including multiple objective integer, nonlinear optimization problems which require further mathematically oriented research. (omitted)

This study aims to compare student self-, teacher-, and objective assessments of elementary science-gifted students' scientific creativity. A science-gifted program on the topic of Hydraulic Machine was implemented to 40 fifth-graders in the Science-Gifted Education Center of an education office in Seoul, Korea for four weeks. The products of the students' activities were assessed by three types of 'Student Self-Assesment', 'Teacher-Assesment', and 'Objective Assessment using Formula'. Based on two essential components of creativity, the scientific creativity is divided into two parts of originality and usefulness. Ideas that satisfy both components can be counted as scientifically creative. The main results of this study are as follows: First, the scores of each week and the average of the overall four-week scores on scientific creativity were significantly correlated. Student self-assessment (r=.687), teacher-assessment (r=.715), and objective assessment (r=.724) appeared consistently over instructional periods. Second, the average scores of student self-, objective, and teacher-assessments were 73.15, 35.72, and 26.60, respectively. The result of student self-assessment on scientific creativity tended to be higher than those of formula and teacher. Third, among the three types of assessment on scientific creativity, a strong correlation appeared between teacher- and objective assessment (r=.974), but neither between student self- and objective (r=.161) nor between student self- and teacher- (r=.213). Fourth, the scores on originality component had a positive correlation between teacher- and objective assessment (r=.713). The scores of student self- and teacher-assessments had a significant correlation too (r=.315), but not between student self- and objective assessment (r=.279). Fifth, the scores on usefulness component did not have a significant correlation between student self- and teacher-assessment (r=.155). Sixth, there was no significant difference on scientific creativity between student self- and objective assessment [${\chi}^2$(1, n=40)=1.667, p<.197]. Not between student self- and teacher-assessment either [${\chi}^2$(1, n=40)=1.616, p<.204]. On the contrary, there was a significant difference between teacher- and objective assessment [${\chi}^2$(1, n=40)=32.593, p<.000]. Seventh, the students were categorized into four groups according to the levels of their scores by student self- and teacher-assessment. The result showed that factors influencing student self-assessment are inherent in the personality traits of gifted individuals, such as self-esteem and perfectionism. The findings suggested that there are challenges for the educators to make efforts to construct consistent assessment methods for scientific creativity.

First of all we tired to find a momentum to boost the value of home economics education as a fixture of the curriculum by analyzing the relation between gender equity education and Home Economics Education. On the other hand it suggests the need of gender equity education in Home Economics Education the related measures and some applicable course of study. And For the purpose of exemplification this study was developed gender equity instruction in Home Economics Education. The results are as follows: First the recent gender equity education in our education system can be interpreted as giving equal education opportunity and equal education objective. Therefore this kind of theory results in the education of Home Economics for both the male and female students. This results can be valued as boosting the availability of Home Economics Education and providing a stepping stone for Home Economics Education Development. Second the ultimate objective of Gender Equity Education is to cultivate a person to be equipped with Gender Equity concept and to implement the concept. Therefore Home Economics Education (Ministry of Education 1995) which has the ultimate objective of improving the quality of the individual and family life can be the most important curriculum for understanding the abstract concept of Gender Equity and providing various practical contents. Third the Gender Equity Education in Home Economics can be realized through the following measures:(1) The efforts to positively restructure the education contents after analysing and evaluating the education contents in terms of the Gender Equity concept. For the purpose of exemplification, this study was developed ‘Gender Equity Instruction in Home Economics Education. (2) The development and application of an interesting course of study for both the male an female students (3) Providing the proper teachers for the male students who want to choose Home Economics.

Purpose: The purpose of this study was to investigate differences of subjective, objective knowledge and educational need about contraceptives according to sex in college students. Methods: Data were collected by a self-administered questionnaire from 84 male and 111 female college students on May, 2008. PASW 18.0 program was used for data analysis. Results: There were significant differences in age, major, grade, place of residence, and experience of sexual intercourse between male and female college students. There was a significant difference in objective knowledge about contraceptives between the two groups, but no significant difference in subjective knowledge. The positive correlation was shown between subjective and objective knowledge about contraceptives. Even when demographic variables such as age, major, grade, place of residence, and experience of sexual intercourse were controlled, sex was a significant influencing factor on subjective and objective knowledge about contraceptives. Educational need about emergency contraceptive pills was significantly different and ranking of educational need about contraceptives was also different between the two groups. Conclusion: These results suggest that different education programs according to sex are needed to maximize the effect of contraceptive education and sexual characteristics are considered to give an education to college students.

Purpose: The 'learning cycle' proposed by Guilbert in 1981 has been accredited as an effective and useful model for curriculum design. Three components of learning cycle, learning objective, instructional method, and assessment are connected organically and form basic structure of curriculum. In this study, we intend to analyze how the learning cycle and its three components are applied to present medical curriculum and examine the points at issue of the learning cycle in medical education. Also, we try to identify the educational significance of the leaning cycle in medical education. Results: First, concerning the learning objective, it was identified that impractical and abstract expressions are major controversial points. Also, there is a need to make learning objectives covering entire medical curriculum. Second, because of various structural problems, it is hard to practice new and various instructional methods. Third, even though there is a growing need for medical curriculum to develop and utilize more various and detailed assessment and evaluation, it was revealed that only are standardized and traditional assessments mainly used. Conclusion: Synthetically, we have some suggestions as follows. First, it is necessary to specify and actualize the learning objectives. Also, instructional methods and assessments should be diversified. And finally, there is a need to build organic and delicate medical curriculum by applying the learning cycle to medical education more actively.

This study analyzed the objective indicators of household economic structures, such as income, expenditure, and debts, as well as a subjective evaluation of economic standards, and compared the households of commuting couples (so called Weekend couples) with those of non-commuting couples. Findings of this study are as follows. First, both husbands and wives in commuter marriages had a higher level of education, were younger, had poorer health, and had shorter working hours than the couples in non-commuter marriages. Second, commuting couples had a significantly higher income than non-commuting couples. In addition, commuting couples had a greater amount of savings, had a higher cost of living, and lower debts than non-commuting couples. Third, commuting couples evaluated their status of household economy more negatively than non-commuting couples. Despite the fact that the commuting couples were more affluent in terms of the objective indicators, including income, savings, and assets, their level of health and psychological well-being were compromised. Lastly, factors determining commuter marriages were the number of years the husband has spent in his job, and the husband's level of education. The shorter the tenure of the husband's job, and the higher the level of husband's education, the more likely the couple was in a commuter marriage.

The optimization design problem of nuclear reactor radiation shield is a typical multi-objective optimization problem with almost 10 sub-objectives and the sub-objectives are always demanded to be under tolerable limits. In this paper, a design method combining multi-objective optimization algorithms with paralleling discrete ordinate transportation code is developed and applied to shield design of the Savannah nuclear reactor. Three approaches are studied for light-weighted and compact design of radiation shield. Comparing with directly optimization with 10 objectives and the single-objective optimization, the approach by setting sub-objectives representing weight and volume as optimization objectives while treating other sub-objectives as constraints has the best performance, which is more suitable to reactor shield design.
