Legislation on pharmaceutical reimbursement decision using economic evaluation results was made in Korea in fm, but has yet to be fully implemented. We evaluated the quality of Korean economic evaluation studies of pharmaceuticals to understand gaps between legislation and implementation. From this evaluation, we propose policy options that might strengthen the research Infrastructure In order to support such studies. We reviewed 23 published studies for drugs conducted between 1996 and 2004. Evaluation criteria included methodological characteristics, healthcare system characteristics, population characteristics, and applicability of results. Large variation in study quality was observed, particularly with study design, outcome data, treatment patterns and interpretation. Korean clinical data used was mostly from observational studies of 1-2 hospitals. Foreign data was extracted from clinical trials that did not Include Asian population and their selection criterion was not clarified. With respect to treatment patterns, medical records and hospital bills were used without adjustment regarding area, hospital type, and others. And next frequent situation relied on expert opinion from academic physicians in specialty practice. preference measures, when used, were not elicited from the Korean population. $78.3\%$ of studies did not clarify the funding source. If the Korean economic evaluation policy is to provide meaningful data for decision makers, the quality of cost-effectiveness studies will need to improve dramatically. This may involve access to or creation of better data, more diverse funding, unproved training of researchers and evaluators, and partnerships with technology manufacturers.

The purpose of study is to propose the possibilities of finding trigonometric function values using trigonometric function graphs instead of the unit circle method. And it is to discuss how to enhance relating trigonometric function value finding to graphs construction, and students conceptual understanding of the properties of trigonometric functions. The conclusions of this study are the effectiveness of function value finding using trigonometric function graphs, the use of a precise term of function value finding given general angles, consideration of a link between function value finding and graphs, and the possibility of teaching trigonometric function graphs in advance of function value finding.

Objective: To evaluate the effectiveness of soft stimulation protocol using GnRH antagonist/clomiphene citrate (CC)/recombinant FSH (rFSH) in patients undergoing controlled ovarian stimulation (COS) with intrauterine insemination (IUI), compared with GnRH antagonist multiple dose protocol (MDP) using GnRH antagonist/rFSH. Methods: Eighty infertile women were randomized to soft stimulation protocol group (n=40) or GnRH antagonist MDP group (n=40). In both groups, IUI was performed 36~40 hours after hCG injection. Statistical analysis was performed using Student's t-test, $\chi^2$ test or Fisher's exact test as appropriate. Results: Total dose and days of rFSH required for COS were significantly fewer in soft stimulation protocol group (p<0.001, p<0.001). A premature LH surge did not occur in any patients of both groups. Clinical pregnancy rate per cycle was similar between the two groups. Conclusion: Soft stimulation protocol provides comparable pregnancy rates to GnRH antagonist MDP despite fewer total dose and days of rFSH, and so can become one of the patient-friendly, cost-effective alternatives for infertile patients undergoing COS with IUI.
