Separation of prescribing and dispensing practice in Korea has changed the service pattern of the pharmacy. The prescription dispensing activities, however, are concentrated excessively on the pharmacies near hospitals or clinics. Thus this study was conducted to estimate the number of optimal dispensing cases for the community pharmacy. Forty-six pharmacies were selected using systematic stratified random sampling method, and ninety-five pharmacists were interviewed on their workload of dispensing and other activities at pharmacies. One hundred and seventy prescriptions were chosen based on the length of drug administration and drug dosage form, and the dispensing time was measured by time-watch method. Also pharmacy benefit claims data were analyzed to identify the characteristics of the pharmacies which performed more than optimal dispensing cases. According to the study results, the average work time per pharmacist per day was found to be 10hours 32minutes and the dispensing activities occupied 7hours 36minutes. It took 5.72minutes on average for each dispensing case. The optimal dispensing case was estimated as 75 cases under the condition of 10hours 32minutes work time and 6% allowance rate. Even though the pharmacies near hospitals or clinics participated dispensing services actively, only pharmacies near clinics dealt with more than optimal dispensing cases. For the pharmacies near hospitals they dealt with less than optimal cases, but drug administration period per prescription was almost 3 times longer than that of pharmacies near clinics. Thus the intensity of dispensing activities such as drug administration period is to be considered to estimate optimal dispensing cases more accurately.

This paper presents a novel type of hybrid dispensing head for IC fabrication and surface mount technology. The proposed mechanism consists of solenoid valve and piezoelectric stack as actuators, and provides positive-displacement and jet dispensing. The positive-displacement dispensing can produce desired adhesive amount without viscosity effect, while the jet dispensing can produce high precision adhesive amount. In order to determine the relationship between required voltage of the piezoelectric actuator and needle displacement, both static and dynamic analysis are undertaken, In addition, finite element analysis is performed in order to find optimal design parameters. Dispensing flow rate and pressure in the chamber are evaluated through fluid dynamic model.

Several research works for finding and optimizing the methods of dispensing high viscosity phosphor used in the fabrication of white LED's are currently in progress. High viscosity phosphor dispensing with a high accuracy is crucial because the dispensing rate and uniformity directly affect parameters such as the CIE chromaticity diagram, color temperature and luminous flux of white LED's. This study presents a novel method of dispensing high viscosity phosphor using electrohydrodynamic printing. The dispensing rate was optimized less than 0.01 mg phosphor using experiments and optimizing the process parameters including the standoff distance from the nozzle to the substrate, ink supply pressure, and multi-step pulsed waveform magnitude ratio. The dispensing rate was measured by dispensing 20 dots using drop-on-demand with the optimized parameters, and the experiments were repeated 10 times to maximize the data accuracy. The average dispensing rate that can be reliably used for high viscosity phosphor dispensing was 0.0052 mg.

Hospital pharmacy services are divided into dispensing affairs for inpatients and outpatients, pharmaceutical service, stock control, intravenous admixture service, drug information service, pharmacokinetic consultation service, education and research work, etc. But among those affairs, dispensing affair for outpatient is perceived as the most important work in Korea, because it is linked directly with hospital service for patients. Therefore, total computer system for dispensing area was adopted from opening point of hospital in 1989 in Asan Medical Center. Utilization of computer system for outpatient dispensing area is as follows; 1) Order communication system of prescription by Total Hospital Information System, 2) Automatic print-out system of direction for use by sticker connected with on-line net work, 3) Use of automatic tablet counting and packaging machines connected with on-line net work. Those computer system resulted in curtailment of pharmacy manpower and shortening of waiting-time for outpatient.

The goal of this research was to find out the effect of dispensing error prevention program on the incidence of the error in a university hospital pharmacy in Daegu. Dispensing error in this research was defined as the error identified during double-checking process, so it does not mean that the wrong dispensing was administered to patient. Drug name error was the most frequently found error, accounting for about one third of all dispensing errors, and was followed by counting error, strength error, dosage form error, and others. Similar drug name was identified as the most frequent reason for the error, taking up about two thirds of all drug name errors. In this research, six months of dispensing error prevention program resulted in statistically significant reduction of dispensing error by 42 percent. Therefore, it is recommended that hospital pharmacy implement such prevention program regularly to reduce the incidence of the error. Finally, it appears that drug approval authority should closely check the similar drug names and have power to command pharmaceutical company to change the name if pertinent.

Background: This study examined the public's perceptions of repeat dispensing as one of the measures to reduce the harmful effects of long-term prescriptions in Korea. Methods: From January 11 to 25, 2021, an online survey was conducted for adults using convenience sampling. A self-developed questionnaire was used. Results: There were 310 respondents, of which 228 (73.5%) preferred repeat dispensing. When considering the additional fee payment, 188 (60.6%) preferred repeat dispensing, and 54 (67.5%) out of a total of 80 chronic disease patients preferred it. It was confirmed that there was a difference in the willingness to repeat dispensing considering the additional cost depending on whether the patient had a chronic disease and the distance from home to the nearest pharmacy. As a result of subgroup analysis for patients with chronic diseases, frequency of outpatient visit, number of prescription days, method of packaging pharmaceuticals, and distance from home to the nearest pharmacy were identified as variables that could well predict the willingness to repeat dispensing considering paying additional fees. The preference for repeat dispensing may vary depending on conditions such as additional cost range, frequency and period of prescription use, disease and patient characteristics, so a careful approach is necessary. Conclusion: It is necessary for the government to consider the introduction of repeat dispensing with interest in the public demand.

Objective: An automated process for medication preparation and dispensing is essential to improve the quality of work. To reduce night pharmacy workload, a new automated dispensing cabinet system was implemented in a hospital emergency medical center. The purpose of this study is to verify that implementation of an automated dispensing cabinet system will influence the efficiency of night pharmacy work. Methods: To evaluate the new system implementation, a retrospective study and survey was performed in the Ewha Womans University medical center. We compared the dispensing and near-miss error rates between the automated dispensing cabinet system and a night pharmacy. The degree of satisfaction of night shift workers with the new system was surveyed. Results: This study showed significantly reduced dispensing rates of night medications (56.1% and 37.3%; p < 0.01) and near-miss night medications (0.27% and 0.17%; p<0.01). Thirty-two persons responded to the survey, and the satisfaction score for the new system was 4.0 (${\pm}0.8$). The scores were high in order of efficiency, management, and convenience. Time requirement was also reduced because of the simple step of only reviewing in the pharmacy with the new system. Conclusion: Due to system implementation, workload was reduced and time was saved for not only night shift workers but also patients receiving emergency discharge medicine. It was suggested that this will have a positive effect on pharmacist medical service and patient safety.
