When teachers for the gifted express metaphors about their teaching, they may develop better understanding and conceptualizing of teaching and enable to choose appropriate teaching strategies for optimizing individualized learning of the gifted. Therefore, the purpose of this study includes to explore metaphors about science teachers' teaching for the gifted in middle schools and classify into types of metaphors. The survey was administered and completed survey instruments by 66 science teachers for the gifted at gifted educational institutions affiliated with local offices of education and 18 science teachers at middle schools were analyzed. It was revealed that science teachers for the gifted described seven types of metaphors about their teaching with characteristics of student-centered (counsel, helper, etc.), teacher-centered (judge, captain, etc.), or student-teacher-interacted (painter, nurse, etc.) types. More than 60% of teachers described their teaching as either student-centered or student-teacher-interacted types. However, percentage of teachers for the teacher-centered and power-oriented type was higher for science teachers for the gifted (33%) than science teachers for regular students (22%). It was also found that female science teachers for the gifted showed higher percentage for teacher-centered and power-oriented (35%) than male teachers (28%) and teachers with BS degree showed higher percentage for student-centered and service-oriented type (33%) than teachers with MS degree (27%). In addition biology teachers for the gifted also were appeared to be more teacher-centered and power-oriented type (60%) than physics (21%), chemistry (6%), and earth science (33%).

To construct a novel vaccine candidate against bovine enterotoxigenic Escherichia coli (ETEC), FanC, the major subunit of K99 fimbriae adhesion, was inserted into secretion plasmid pYA3560 containing a ${\beta}-lactamase$ secretion system. This was then transformed into ${\Delta}asd$ ${\Delta}crp$ Salmonella (S.) Typhimurium and designated as JOL950. Secretion of recombinant fanC fimbrial antigens was confirmed by immunoblot analysis. Groups of mice were inoculated with single or double doses of JOL950. Another group was used as a negative control. Compared to control mice, all immunized mice had significantly higher levels (p < 0.05) of serum immunoglobulin (Ig)G, and secretory IgA against FanC. The IgG2a and IgG1 titer assays revealed that immunization highly induced IgG2a compared to that of IgG1, indicating that T helper-1- related cell-mediated immune responses may be elicited by JOL950. The results show that both systemic and mucosal immunities against selected fimbrial antigens of bovine ETEC expressed by a live attenuated S. Typhimurium strain are prominently produced in mice immunized with JOL950 via an oral route.

Recently, introduced open education, there are some models applied several cooperative teaming, but there is no case in applied Jigsaw Ⅱ. So this research is selected objects which are 147 students in the fifth grade in 1999' school year and 143 students in 2000's on Yongwon elementary school. It makes share a partial responsibility for planner, leader, investigator, helper, writer and reporter in the small groups, and apply the Jigsaw Ⅱ model. Qualitative and quantitative analyses show that they have effects of Jigsaw Ⅱ cooperative Learning on Student's knowledge, inquiry ability and attitudes on Elementary School Science Study. The final results are following. The significance of Knowledge has .02 in 1999 and .01 in 2000. Testification of Inquiry ability has 1.75 in 1999 and 2.25 in 2000. The significance of Attitudes has .03 in 1999 and .00 in 2000. Research that has emerged from the cooperative teaming has led us to better understandings of multi purposed roles, interactions, and communities that arise when students work together to team science. Each of students can also cooperative as co-builders, working as equal participants to create a product that is better than that while would have built by either individual alone. Upon asking their intention, cooperative loaming shows more participation.

In this study, the investigator examined employees' work-family conflict, and analyzed its relationship with family health, to clarify the two-way influence of work-family and to verify the influence of a family friendship system based upon work-family compatibility and a healthy family. Data from 379 married female and male corporate employees were collected. Collected data were analyzed on the SPSS WIN 12.0 program. Study findings are as follows: First - For the individual, in domain variables of work-family conflict according to socio-demographic characteristics, gender has a significant influence upon strain-based conflict, family interference with work, and time-based conflict. Second - Work domain variables such as occupation, career, employment type, and working hours have a significant influence upon work interference with family, while career, and a working couple have a significant influence upon family interference with work. Finally - average housework hours and children have a significant influence upon work interference with family, whereas the length of a marriage, the average housework hours, and a housework helper have a significant influence upon family interference with work.

A novel cholesterol-based cationic lipid containing a tri-2-hydroxyethylamine head group and ether linker (Chol-THEA) was synthesized and examined as a potent gene delivery vehicle. In the preparation of cationic liposome, the addition of DOPE as helper lipid significantly increased the transfection efficiency. To find the optimum transfection efficiency, we screened various weight ratios of DOPE and liposome/DNA (N/P). The best transfection efficiency was found at the Chol-THEA:DOPE weight ratio of 1:1 and N/P weight ratio of 10~15. Most of the plasmid DNA was retarded by this liposome at the optimum N/P weight ratio of 10. The transfection efficiency of Chol-THEA liposome was compared with DOTAP, Lipofectamine, and DMRIE-C using the luciferase assay and GFP expression. Chol-THEA liposome with low toxicity had better or similar potency of gene delivery compared with commercial liposomes in COS-7, Huh-7, and MCF-7 cells. Therefore, Chol-THEA could be a useful non-viral vector for gene delivery.

Systemic lupus erythematosus (SLE) is characterized by dysregulatory production of proinflammatory cytokines and helper T (Th) cytokine-dependent autoantibody production. This study aims to investigate the protective effect of baicalin on the dysregulatory production of proinflammatory cytokines and Th cytokines in pristane-induced lupus mice. Mice were received i.p. a single injection of 0.5 ml of pristane, and then, later about 3 months, were used as a pristane-induced lupus model. The pristane-induced lupus mice were administrated orally with baicalin 50 mg/kg once in a day for 10 days. Immune cells obtained from the pristane-primed lupus control group (lupus control) and baicalin-treated pristaneprimed lupus mouse group (BAC lupus) were cultured for 24 h or 36 h with/without mitogens. These results demonstrated that LPS-induced production of macrophage and splenic TNF-${\alpha}$ and Con A-induced production of thymic IFN-${\gamma}$ were attenuated in BAC lupus compared to lupus control, while LPS-stimulated production of macrophage IL-10, Con A-stimulated production of splenic IL-10 and, $PGE_2$-reduced production of splenic IFN-${\gamma}$ enhanced. Therefore, these findings suggest that baicalin may protect from autoimmunity and disease activity in lupus via modulatory effect of proinflammatory cytokine overproduction and Th cytokine imbalance.
