  • The purpose of this study was to provide basic data for better design of Pharmacy after introducing the new system of separation of dispensing from prescribing medicine. To analyze characteristics of interior design in pharmacy and to measure worker satisfaction, a survey was conducted with 255 workers who serve at any Pharmacies located in Busan, Korea. For data analysis, descriptive statistics, t-test, One-way ANOV A were performed with the SPSS Win program(Ver. 10.0). The major findings were as follows: 1) As a result of analyzing the role and functions of the pharmacist is to be classified into many items such as entrance, a waiting room, a dispensary, a medication & consultation area, a drug storage and a worker's room. 2) Natural substances should be used more widely instead of using chemical substances for the pharmacy interior design as finishing materials 3) Pharmacy worker's satisfaction with dispensary is specially low among the total satisfaction which is :slightly higher than the average. 4) The degree of satisfaction between pharmacy workers from different groups varied depending on work hours, and especially long time(over 10hrs) workers showed dissatisfaction. Pharmacy managers need to consider the option of expanding convenience facilities. 5) According to the satisfaction analysis for each pharmacy conditions, the group who worked in 30-pyeong spaces were most satisfied. Since the 30-pyeong space is most standardized space research should be conducted.

  • 1. 목적 자동분주기를 이용하여 검사한 Cyclosporine검사에서 표준액들이 curve를 벗어나고, 결과값의 재현성이 크게 떨어지는 것이 발견되었다. Cyclosporine검사는 다른 검사와 차이점이 methanol과 전혈을 혼합 후 원심분리 하여 methanol 추출액을 사용하여 검사를 한다는 것이다. 검사 결과 이상의 원인이 methanol 사용에 의한 것으로 파악되어 본 실험을 시작하였다. 본원에서 사용하는 분주기는 Perkin Elmer 사의 Multiprobe II plus 로, 분주하는 액체의 점도, 샘플링 tip의 size, 사용하는 모터의 속도에 따라 여러 설정값을 조정하라고 안내되어 있을 뿐 정확한 지침은 없었다. 이에 사용하는 액체별 분주성능을 측정하고 최적의 분주성능을 위한 설정값을 찾기 위해 연구하였다. 2. 대상 및 방법 분주력 측정을 위해 4가지 용액(water, serum, methanol, PEG 6000(25%))와 $TSH^{125}I$ tracer (515 kBq)을 사용 하였고, 실제 결과 값을 비교하기 위해 2016년 1월에 본원에 검사 의뢰된 Cyclosporine검체 29개를 측정하였다. 4가지의 용액을 multi pipette을 이용하여 각각 $400{\mu}l$ 분주하고 tracer $100{\mu}l$씩을 섞어 용액별로 8개의 검체를 준비하였다. 준비된 sample을 분주기로 $100{\mu}l$씩 분주하여 CPM을 측정하고, 용액별로 CV(%)를 계산하였다. 그리고 분주기의 air gap, 분주속도와 지연시간을 변경한 후 다시 분주하여 측정한 CPM을 CV(%)로 계산하여 설정 값 변경에 따른 CV(%)값의 변화를 측정하여 최적의 설정 값을 찾는다. Cyclosporine검체 29개를 (1)manual검사 (2)기존 설정 값으로 검사 (3)수정한 설정값으로 검사 했을 때의 결과를 비교하였다. 용액별 분주력 평가는 CV(%)를 이용하여 계산하였고, 실제 검사 결과 값의 비교는 manual검사 결과를 기준으로 기존 설정 값으로 검사 했을 때, 수정한 설정 값으로 검사 했을 때의 결과 값을 Difference(%)와 상대오차(%Relative error : %RE)로 비교해 보았다. 3. 결과 4가지 용액과 tracer를 섞어 분주한 CPM의 CV(%)는 water 0.88, serum 0.95, methanol 10.22, PEG는 0.68로 methanol을 제외한 용액들은 1% 이내였으나, methanol은 CPM 차이가 두드러졌다. methanol 분주를 기존 설정 값인 Transport air gap 0에서 2와 5로 변경하여 검사 시 CV(%)는 각각 20.16, 12.54, System air gap 0에서 2와 5로 변경 시 8.94, 1.36으로 나타났다. System air gap 2, Transport air gap 2로 변경 시 CV(%)는 12.96, System air gap 5, Transport air gap 5로 변경 시 1.33 이었고, Dispense speed를 300에서 100으로 변경 시 CV(%)는 13.32, Dispense delay를 200에서 100으로 변경 시는 13.55인 것으로 나타났다. 분주기를 이용하여 기존설정 값으로 검사 시에는 manual검사 결과 값에 비해 평균 99.44%증가 하였고, 상대오차는 93.59%로 나타났다. 수정된 설정 값(System air gap 0에서 5로 변경, 다른 설정은 기존과 동일)으로 검사 했을 때는 manual검사 결과 값에 비해 결과가 평균 6.75% 증가 하였고, 상대오차는 5.10%로 상대오차의 허용기준치 10%에 비하여 양호한 결과가 나왔다. 4. 결론 Transport air gap, Dispense speed, Delay time을 조정하였을 때는 CV(%)가 증가하였고, System air gap을 조정 하였을 때 CV(%)가 현저하게 감소하였다. 실제 검사결과에서도 이를 확인 할 수 있었다. methanol을 이용한 Cyclosporine검사 kit는 올해 2월에 단종이 되었지만, 분주기를 사용함에 있어 용액에 따른 분주성능에 차이가 있을 수 있음을 염두해 두어야 하고 새로운 용액을 분주해야 할때는 미량저울로 분주량을 측정하거나 CPM으로 분주성능을 측정하여 해당 용액이 분주기를 사용함에 적절한지 검증 후 사용하여야 할 것으로 사료되어 본 실험결과를 보고하고자 한다.

  • Objective: This study is to review the current state of services offered to pharmacy users, and develop a service design converging a prescription service and a smart phone application service in order to enhance patients' experience at pharmacies and home. Background: Under the new medical system; separation of prescribing and dispensing drugs, a doctor writes a prescription to their patients and patients have their prescription filled at the pharmacy. As the number of flue, allergy and atopy patients has increased, waiting lines have been longer at pharmacies. Besides, the current medical service system lacks of providing proper information on prescribed pills to patients. There are already services offered during waiting times such as offering free drinks, magazines or suggesting general drugs which you can buy without prescription, however they neither cover the current medical service's shorts nor shorten the waiting time. Method: I researched objective and perceived waiting times reduction methods, the current service status at pharmacies, and the government's policy direction in a medical service. Also, I observed a patient's journey from the hospital to pharmacy and then home. I examined the circumstance at pharmacies, patients' behaviors and their thoughts during their journey, and extracted three main goals to design a service in order to help patients have positive perception during the waiting time; (1) to reduce the perceived time by the way of visualizing time and offering readings about what patients consider necessary, (2) to educate patients what they are into and how to get through, (3) to establish trust among patients, doctors and pharmacists. Based on three goals, I designed a structure and a wireframe for a new service application of smart phones. Results: With a new service design for pharmacy users, users can track their medical record and visit the information about their current medical treatments anytime. Also the service helps patients build reliable relationships with doctors and pharmacists. Conclusion: Experience is not just an activity but series of multiple activities. The serving range of a medical service should not be determined by stakeholders but user's holistic experience. By approaching a service design with a holistic vision, it can enrich not only a temporary experience but also a whole life well being. Application: Since there are already many service applications advising patients about their illness and finding right doctors, this service design is focused on the experience from getting a prescription till feeling better. The next move is to combine those two parts medical services and design an integrated service application. As a prescription is going to be coded in numbers, we might consider to design an un-attended pharmacy which can shorten huge amount of time for filling prescriptions.

  • 2000년도 의약분업으로 심화된 대체 조제에 대한 논란은 의사의 사전 동의 없이 대체조제 가능 품목을 식품의약품안전청장이 생물학적 동등성이 있다고 인정한 품목으로 제한함으로서 마무리되었다. 이에 발맞추어 식품의약품안전청(KFDA)은 후발 의약품에 대한 생물학적 동등성 시험 기준을 개정하였으며, 이 중에서 눈에 띄는 부분은 통계적인 고려 사항이다. 특히, 대조약과 시험약간의 동등성 판단을 위한 비교항목의 로그 변환을 명시한 것은 통계적 검증의 타당성 확보뿐만 아니라 국제적인 의약품 허가 추세에 부응한 바람직한 조치라 할 수 있다. 본 논문에서는 개정된 생물학적 동등성 시험 기준에서 고려 된 AUC와 Gmax의 로그 변환(log transformation)을 중심으로 그 배경과 통계적 의미를 고찰해 보고, 기존의 생물학적 동등성 판단 기준과 비교 검토해 보고자 한다. 또한 모의실험을 통해 개정된 기준의 통계적 타당성을 확인하고, 올바른 생물학적 동등성 판단을 위한 최소 표본수를 제안해 보기로 한다.

  • Background: In a prospective cohort study of antiemetic therapy conducted in Malaysia, a total of 94 patients received low emetogenic chemotherapy (LEC) with or without granisetron injections as the primary prophylaxis for chemotherapy-induced nausea and vomiting (CINV). This study is a retrospective cost analysis of two antiemetic regimens from the payer perspective. Materials and Methods: This cost evaluation refers to 2011, the year in which the observation was conducted. Direct costs incurred by hospitals including the drug acquisition, materials and time spent for clinical activities from prescribing to dispensing of home medications were evaluated (MYR 1=$0.32 USD). As reported to be significantly different between two regimens (96.1% vs 81.0%; p=0.017), the complete response rate of acute emesis which was defined as a patient successfully treated without any emesis episode within 24 hours after LEC was used as the main indicator for effectiveness. Results: Antiemetic drug acquisition cost per patient was 40.7 times higher for the granisetron-based regimen than for the standard regimen (MYR 64.3 vs 1.58). When both the costs for materials and clinical activities were included, the total cost per patient was 8.68 times higher for the granisetron-based regimen (MYR 73.5 vs 8.47). Considering the complete response rates, the mean cost per successfully treated patient in granisetron group was 7.31 times higher (MYR 76.5 vs 10.5). The incremental cost-effectiveness ratio (ICER) with granisetron-based regimen, relative to the standard regimen, was MYR 430.7. It was found to be most sensitive to the change of antiemetic effects of granisetron-based regimen. Conclusions: While providing a better efficacy in acute emesis control, the low incidence of acute emesis and high ICER makes use of granisetron as primary prophylaxis in LEC controversial.

  • This study aims to help improving the quality of military food service as identifying awareness, attitudes and satisfaction of cooking soldier on their duties and providing basic data to find out alternatives on the basis of identified data. The analysis results are described as follows. For general demographics of subjects, sergeants consisted of the highest percentage of population as 38.8% in terms of the rank. For educational background, the percentage of graduates or college students was 82.5%. For the characteristics of job performance of cooking soldier, those who studied entirely different courses from cookery and became to work as cooking soldier were 92(89.3%) of total subjects. For the question why they became to work as cooking soldier, the response that they didn't know the reason showed the highest percentage as 63.1%. Those who selected cooking soldier because they were interested in cookery were only 25.2%. And 94.2% of the population had no certificates related to cookery. With respect to awareness on training period to carry on duties as cooking soldier, 3 months were selected as the most appropriate period as 36.9%. In accordance with research on job percentage of cooking soldier, 'cleaning and washing' consisted of the highest percentage among ordinary duties as 16.8%, followed by 'cooking' as 12.3% and 'food dispensing' as 11.8%. This study suggests as follows on the basis of the results of this researches. Cooking soldier requires expertise, but the privates with short period of service are discharged from military service when they are accustomed to their duties and become experts. Accordingly, the cooking soldier system could not achieve more than its ordinary performance. Therefore, it is required to post non-commissioned officers who can serve for a long time as the special resources.

  • Objective : To evaluate the relative benefits and the costs associated with the introduction of the new pharmaceutical provision called 'Mandatory Prescription System' which separates the role of physicians from that of pharmacists with respect to the prescription and dispensation of from the perspective of consumers (i.e., patients). Methods : The costs of the system were measured by considering both direct and indirect costs. Direct costs included additional payments for ambulatory care and dispensing fees that occurred under the new system. indirect costs consisted of transportation expenses and costs related to time spent for physician consultation, waiting for the prescriptions to be filled, and extra traveling. Benefits identified in this study were the reduction of drug misuse and overuse, and the overall decrease in drug consumption among the Korean population. Sensitivity analysis was peformed for the inclusion of benefits for outpatients of hospitals, price elasticity, and increased fees for established patients. Results : The net benefit was estimated to be about minus 1,862 billion won and the benefit-cost ratio was 0.478. This indicates that the costs of 'Mandatory Prescription' outweigh its benefits, relative to the previous system. The sensitivity analysis results for all the variables considered in this study consistently showed the benefit-cost ratio to be less than 1. Conclusion : The results of this study suggest that implementing Mandatory Prescription System in Korea might be inefficient from the consumer's perspective. The results of this study do not coincide with the results of previous studies, presumably because of the differences in study design and in which items of costs and benefits were considered.

  • Purpose: 2-[$^{18}F$]Fluoro-2-deoxy-D-glucose ([$^{18}F$]FDG) particularly plays as a important role in Positron Emission Tomography (PET) imaging in nuclear medicine. Domestic [$^{18}F$]FDG auto synthesizers are installed in Seoul National University Bundang Hospital (SNUBH) at June 2008, these modules were known that it's synthetic yields were guaranteed in average $45{\pm}5%$ so far. To improve yields and convenience of domestic [$^{18}F$]FDG auto synthesizer, numerous trials in reaction time, base concentration, pressure and temperature were performed to increase [$^{18}F$]FDG yields. Materials and Methods: Several synthetic factors (temperature, time and pressure) and shortcoming were corrected based on many evaporation test. Syringe dispensing of tetra-butylammonium bicarbonate (TBAB) was replaced with micro pipette to prepare tetrabutyl ammonium fluoride salt ([$^{18}F$]TBAF). Troublesome refill of liquid nitrogen every 2 hours which was used to protect vacuum system was changed to charcoal cartridge, base guard filter. To monitor the volume of delivered $[^{18}O]OH_2$ from cyclotron by surveillance camera, we set up the volumetric vial on the cover of the module. In addition to, the recovery vial was added in [$^{18}F$]FDG production system to recover [$^{18}F$]FDG loss due to the leak of valve ($V_{13,14}$) in [$^{18}F$]FDG purification process. Results: When we used micro pipette for adding TBAB ($30\;{\mu}L$ in 12% $H_2O$ in acetonitrile), this quantitative dispensation has enabled to improve $5.5{\pm}1.7%$ residual fluorine-18 activity in fluorine separation cartridge compared to syringe adding. Besides, the synthetic yields of [$^{18}F$]FDG has increased $58{\pm}2.6%$ (n=19), $58{\pm}2.9%$ (n=14), $60%{\pm}2.5%$ (n=17) for 3 months. The life cycle of charcoal cartridge and base vacuum was 3 months prior to filling liquid nitrogen every 2 hours and additional side separator can prevent pump corrosion by organic solvent. After setting of volumetric indicator vial, the operator can easily monitor the total volume of irradiated $[^{18}O]OH_2$ from cyclotron. The recovery vial can be used for the stabilizer when an irregular [$^{18}F$]FDG loss was generated by the leak of valves ($V_{13,14}$). Conclusions: We has optimized appropriate synthetic conditions (temperature, time, pressure) in domestic [$^{18}F$]FDG auto synthesizer. In addition to, the remodeling with several accessories improve yields of domestic [$^{18}F$]FDG auto synthesizer with reliable reproducibility.
