Imaginable. Ms. Lynn Vanatta of Air Liquide America Corp. Dallas, TX ; described the development and validation of a protocol for the determination of low ppb levels of Br , Cl , PO43, and SO4 in high-purity hydrogen peroxide used in the semiconductor industry. Weighed aliquots were placed into tarred bottles. Platinum foil squares were placed into the bottles. These were capped, but not sealed, and placed into a water bath. After a few hours, the splatter from the top of the bottles was removed by sealing and inverting the bottles several times. The bottles were again opened and placed in the bath for six more hours. T h i protocol was effective in removing almost all the peroxide. Then, the analytes were assayed by IC using a sacrificial concentrator column to protect the analytical columns. Ultrafast IC Perhaps the most interesting new development in column technology was presented in a poster by Dr. Panos Hatsis of the University of A l Edmonton, Alberta, Canada ; . Dr. Hatsis used a new Chromalith Rod column Merck KGaA, Darmstadt, Germany ; for the separation of anions using ion pair chromatography with tetrabutyl ammonium chloride ion pairing agent. The structure of the column resembles a porous sponge, with large throughpores. This provides much higher permeability compared to columns packed with small-diameter beads, yet the efficiency is similar to that obtained with columns packed with 35 m particles. With this, the column can be eluted at 15 mL min, which gives a chromatogram of the common anions in about 15 sec, compared to about 10 min using conventional technology. IC-MS Dionex has been selling the Thermo Finnigan San Jose, CA ; AQA mass spectrometer as part of its IC-MS system for about two years. The AQA is a single-quadrupole mass spectrometer with an atmospheric pressure ionization API ; interface that can operate in either the electrospray ionization ESI ; or atmospheric pressure chemical ionization APCI ; mode. Clearly, this is a major extension of capability, assuming that the background electrolyte does not present a problem. Some mass spectroscopists get really upset if someone brings them a sample in a solution containing nonvolatile salts. The use of the IC suppressor in IC-MS looks like it has some definite advantages for both allowing the use of standard IC eluents and for removing nonvolatile counterions from the samples. In addition, the AQA has a cleaning feature that helps keep the source from plugging with nonvolatile salts. Ms. Roseanne Slingsby of Dionex described some uses of IC-MS for cations and anions in pharmaceutical applications, employing 2-mm-i.d. columns in both short and standard length formats. Since the 2-mm-i.d. columns use a quarter of the flow rate of 4-mm columns, they are more compatible with ESI or APCI in terms of sensitivity and ruggedness. She used 2-mm ASRS-Ultra and 2-mm CSRS-Ultra sup.

In general terms, the equity of Honduran banks is tight given the high levels of unproductive assets in their balance sheets. At September 2003, fixed, foreclosed and unreserved nonperforming loans more than 90 days ; accounted for a high 71% of equity. At that date, the system's equity to assets ratio was 9.0%. The minimum capital to risk-weighted assets ratios required by the financial authorities in Honduras is 10%. Tier I capital is made up of paid-in capital and legal reserve, while Tier II capital includes statutory reserves, earnings not yet distributed, revaluation of fixed assets, same-year earnings and subordinated debt. Partment of Urology, Haedong Hospital; 3 Department of Urology, Chunhae Hospital, Busan, Korea Purpose: To evaluate the long-term outcomes and complications of the tensionfree vaginal tape TVT ; procedure for treating stress urinary incontinence SUI ; in women, compared with the data at 3 years with 7 years. Materials & Methods: Forty-eight patients were followed up for at least 3 years following surgery, and 40 were at least 7 years. Preoperatively the patients were evaluated with Stamey grade and urodynamic testing. During the postoperative period, the objective and subjective success rate, along with the postoperative complications, were evaluated. The mean age was 56.0 years. The patients were classified according to their symptom grade; grade I n 9, 18.7% ; , grade II n 36, 75.0% ; , grade III n 3, 6.3% ; . Results: Eighty-eight patients completed questionnaires for evaluation of the subjective outcome. Mean operative time was 31 min 27-52 ; . Mean hospital day was 3.2 day. Postoperative success rate was 93.7%. Postoperative complication was 12 case. 2 case of them was UTI symptom, suprapubic pain was 2 case, urgency was 5 case and acute retention was 3 case. The follow-up period was a mean of 49.3 months 42-59 ; 73.8 months 75-92 ; . The TVT procedure remained successful rate was 92.5% after 7 years. There were no serious or long-term complications related to the procedure. The age and prior pelvic surgery history were related to the change of cure rate. Conclusions: As analyzing and comparing the long term follow-up data, TVT sling operation is a safe, simple and effective procedure for the treatment of female stress urinary incontinence, like shortterm effect.

The purpose and processes of evaluation. A list of required and optional assignments was developed with corresponding point values. The course participation policy was developed by the students on the first day of class. Self- and peer assessments were incorporated into one required and two optional assignments. Course delivery was modified to allow for individual and group activities during class and minimal reliance on lecturing. Results: Sixty-one percent of students n 5 128 ; completed 4 of the 5 optional assignments. All students selected the learning log assignment. Of the eight students who completed all or part of every optional assignment, one took the optional final exam. Course evaluations indicate students appreciated attempts to accommodate different learning styles but felt there were too many writing assignments and not enough role playing opportunities. Despite these comments, only 29% of students selected the group role play assignment. Underestimation of the number of assignments students would complete resulted in grading delays which affected student attitudes about the course overall. Implications: Learner-centered teaching techniques can inspire students to work hard to achieve the desired grade. The design of the grading system and time required to assess students are important considerations when using learner-centered teaching. Based on student and faculty feedback the course will be revised to include more role playing opportunities and fewer writing assignments. Assessing Preceptor Understanding of a New Student Evaluation Tool. Raquel Rodriguez, University of Minnesota; Rodney A. Carter, University of Minnesota; Doneka R. Scott, University of Minnesota; Roberta A. Sislo, University of Minnesota. Objectives: To explore the level of understanding of the new APPE evaluation tool based on educational outcomes developed by the University of Minnesota College of Pharmacy. Methods: In this evaluation instrument, the performance level of an entry level practitioner ELP ; was the common standard against which student performance was evaluated on a 5 point scale with .4 indicating good performance. Evaluations were collected for the first three rotations of 2006 when performance expectation by students would be lower than at the end of the academic year. One-hundred fifty-three 153 ; preceptors were identified, based on their rating of students .4 for all outcomes during the first three APPEs. These preceptors were sent an online survey. The survey asked to evaluate the grading instrument, clarity of the instructions, and their participation in training related to the evaluation instrument. Results: Thirty-four percent 34% ; of preceptors completed the survey. Seventy-five percent 75% ; stated that their students did not perform at the level of an ELP even though their evaluations indicated such, suggesting an inappropriate use of this tool. Fifty percent 50% ; of the respondents participated in at least one the training opportunities provided by the College. Forty-two percent 42% ; of the respondents used the online instructions and 63.5% of those respondents rated the instructions as very clear or clear. Implications: Though multiple educational methods were employed regarding the new evaluation tool and preceptors responded that the instructions were clear, the evaluation results did not show consistent, appropriate use of the instrument. Assessing Student's Perceived Creativity and Analytical Skill Improvement for a Self-Care Course Assignment: Project Skunkworks. Carrie M. Maffeo, Butler University; Erin Albert, Butler University. Objectives: The objectives of this student project were to assess students' ability to think both analytically left brained ; as well as creatively right brained ; during a women's health project assignment in a Self Care course utilizing a small team Skunkworks project model and to assess students' perceptions of their left and right brained ability before and after the assignment. Methods: Student's completed a pre- and post- electronic survey to assess changes in perceptions of their own skills necessary to work in a Skunkworks setting. The skill areas the student were assessed included: leadership, research ability, creativity, idea development, writing, verbal communication, selling ideas, and working in a team. Students in small teams 4-5 students ; had to identify an existing women's health overthe-counter product and propose an innovation. The groups then had to present or sell their innovative women's health product to their classmates by highlighting the products innovation. Group projects were assessed by submitting a written assignment as well as their group presentation. As an incentive for creativity, the class voted on the best group project and bonus points were awarded. Results: All groups presented their products to the class using various media and visual aids video commercials, flyers, product demonstrations ; . Preliminary analysis of the pre- and post- survey suggests that students' perceptions in all of the skill domains listed above improved numerically on a 5 point Likert scale. Complete survey results and statistical analysis will be presented. Assessing the Quality of Pharmacy Medicine Rotations Through a Survey of Past Alumni. Nancy T. Williams, Southwestern Oklahoma State University; Edna Patatanian, Southwestern Oklahoma State University; Elizabeth A. Poorman, Southwestern Oklahoma State University; Brian Murray, Southwestern Oklahoma State University. Objectives: With growing numbers of students and a frequent shortage of full-time faculty, pharmacy schools often rely on volunteer preceptors adjunct clinical faculty for training students during their advanced experiential rotations, particularly those dispensing and elective rotations. However, core medicine ambulatory clinical rotations may also not be routinely conducted by full-time faculty, thus raising concern about the quality of the rotation experience and continuity among the practice sites scattered across the state. The purpose of this project is to 1 ; determine if our core medicine ambulatory rotations are adequately preparing students for pharmacy practice, and 2 ; evaluate if this clinical experience is consistent among the various preceptors. Methods: A survey was mailed in early February to all alumni who have graduated from our pharmacy program within the past three years, which are approximately 250 pharmacists. The survey initially asks general questions about the required core medicine ambulatory rotational experiences as a whole, followed by specific questions about each medicine rotation and its preceptor. Feedback from recent graduates was chosen over current student evaluations because perspectives differ as practicing pharmacists versus students. Additionally, we want to learn areas of improvement to better meet the educational needs of future pharmacy students. The university institutional review board approved the survey. Results: Research in progress. Implications: The results of this survey will provide insight into recent graduates' attitudes and perceptions of the core medicine ambulatory rotations. If negative trends about certain rotations or preceptors are observed, then suggestions for improvement will be offered. Assessment of Clerkship Grades Assigned by Preceptors Pre- and Post- Grade Inflation Educational Seminar. Laurie L. Briceland, Albany College of Pharmacy; Teresa J. Lubowski, Albany College of Pharmacy; Robert A. Hamilton, Albany College of Pharmacy. Grade inflation is the situation wherein a fixed letter grade comes to represent a lower level of student performance, such that the majority of students receive higher grades than past students ; and or produce a lower quality of work and lesser achievement of educational outcomes. In an effort to bring grade inflation to preceptors' attention.
