  • Recently, for successful lactation, many breastfeeding mothers seek various products, including herbal medicine, dietary supplements, and prescribed medicines, to improve milk production. As demand for galactogogues grows, it is highly possible that pharmaceutical galactogogues may be adulterated with illegal products to maximize their efficacy. For continuous control and supervision of illegal products, we developed and validated a simple and sensitive LC-MS/MS method capable of simultaneously determining five galactogogues. Chromatographic separation was conducted using an Agilent Poroshell $120SB-C_{18}$ column with a mobile phase consisting of 20 mM ammonium formate (pH 5.4) and 100 % acetonitrile. The total run time was 13 min per analyte. The proposed method was performed according to the guidelines of the International Conference of Harmonization and it produced reliable results. This method showed high sensitivity and specificity, with a limit of detection (LOD) and limit of quantitation (LOQ) of 0.01-0.82 ng/mL and 0.02-2.45 ng/mL, respectively, for the solid- and liquid-type samples. Specificity was evaluated by analyzing matrix-blank samples spiked with the target compounds at LOQ levels, which provided a good separation of all peaks without interference. Additionally, the repeatability and intermediate precision were typically <15 %, whereas the recovery was 80-120 % of the values obtained using blank samples. Thus, we concluded that this method could be used for the identification and quantification of galactogogues in food or herbal products.

  • This research examines the relationship between the characteristics of Government S&T Research Institutes (GRI) and their institutional performance evaluation system. First, based on Kaplan & Norton (1992) Balanced Scorecard Model, six perspectives suitable to Korean GRI are derived. Second, personnel who works on evaluation job classified current performance measures into the six perspectives. Analyzing comparative weights of individual perspectives, the characteristics of performance evaluation systems among institutes are derived and compared with their missions. The results are as follows: First, GRI evaluation systems put most weight on the customer perspective and least weight on the financial perspective. This result complies with Korean GRI's missions and strategies as well as findings of foreign cases. Second, Basic-technology GRI group relatively more priotizes long-term customer perspective, while Applied-technology GRI Group relatively more priotizes short-term customer perspective. Public-technology GRI Group is located in the middle in terms of priority of customer perspectives. Third, for three yews (2000-2002), performance measure weights of Basic-technology Group are changed much less than those of the other two groups. Further research are needed for reasons of drastic changes for Applied-technology and Public-technology groups and some abnormally high and low measure weights.

  • In this study, we have developed the performance evaluation model for the optimal soil remediation technology selection. Performance evaluation model is composed in the evaluation of two steps. In the first stage, the candidate technologies are derived according to the conditions of drilling, type and concentration of pollutants, and the saturated/unsaturated of target site. In the second stage, each individual candidate technology is evaluated by performance evaluation model. The performance evaluation model has 5 groups of evaluation items and 12 evaluation items which have their own evaluation index and their own weights through the AHP approach surveying 40 experts. From the case study of actual design cases, the applicability of the performance evaluation model was confirmed.
