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.

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.

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.

In this paper, Computer Colour Matching and Kitchen System (CCMKS) is developed on the basis of delphi package and one-chip processor with fuzzy-PID control. CCMKS will be widely used in the colour dyeing industry as an integrated colour matching and dispensing system which have more advantages than the conventional matching or dispensing system, when controlling the real dyeing processes. Delphi is utilized in making database and search/matching routes. The developed matching function reduces the search and matching time to about one third. One-chip processor is designed and manufactured for the distributed control of three-phase induction motors. Fuzzy-PID control is applied to the speed control of three-phase induction motors for a very precise weight of colour at CCMKS. The developed kitchen function decreases the dispensing time to about one twentieth. The experimental results show CCMKS has more excellent search time, more precise weight and much high fidelity than conventional colour matching or dispensing system, in the performance.

Biological and chemical assays(e.g., clinical tests for medical diagnosis) are needed to handle small liquid volume with high accuracy and high reliability. Many micro-dispensing systems using various actuation methods have been developed and applied. In this research, we confirm repeatability of the cartridge-type dispensing system with various measuring methods for guarantee of an acceptable reliability. We systematically examine the dispensed volume variation and dispense rate during 500,000 shots of sequential actuation. Using the same method, we confirm the repeatability of dispensed volume while varying operating conditions and design parameter(i.e., outlet size) of the dispensing system. Also, we examine the consistency of the dispensed volume of droplet while varying the operating pressures. Furthermore, we repeatedly measure differences between an actual dispensed volume and a target volume. According to our results, it is expected that the stable and reliable performance of our dispensing system can effectively be used in various applications containing bio-solutions.

Fiscal crisis in the medical insurance system has put the pressure upon hospitals by increasing the rate of curtailment, since the implementation of the separation of prescription and dispensing of medicine. The purpose of this study is to analyse the curtailment of mdical and drug expenditure before and after the system of separation between prescribing and dispensing and to suggest the problems about current inspection system. Data were obtained from 13 general hospitals and used for analysis of trends on medical & drug expenditure, and curtailment in 1999-2000 at three months intervals. The results were as follows; The scale of curtailment for drug expenditure has been increased on outpatient and inpatient since 2000. For the curtailed drug cost with outpatient, the ratio of curtailed drug expenditure has been increased in the case of prescription within the hospital. These results suggest that review system in social insurance were over-focused to control the cost and it might to impede the validity of review function in insurance system. Therefore, it' s needed to develope the scientific and reasonable criteria for Inspection and evaluation of durg expenditure.
