Delivery of a good quality of service in an efficient manner requires matching the supply of capacity with customer demand. Much research has employed queueing models that analyzed the service system on the basis of independent and stationary customer arrivals. However, the appointment system, which is widely used to facilitate customer access to service in many industries including healthcare, has significant influence on the customer arrival process so that the independent and stationary assumption does not hold in an appointment-based service system. In this regard, this paper aims to propose a model for accurate illustration of the appointment-based customer arrival process. The use of the proposed model allows us to evaluate the overall system performance such as mean waiting time and service level under various appointment policies instead of conducting simulation studies.

The appointment system is widely used to facilitate customer access to service in many industries including healthcare and others. Because of its importance, much research has investigated how to build an effective appointment policy under various environments. However, most research has considered a single-server service system. The objective of this work is to evaluate several appointment policies in a two-stage service system in which multiple servers are available and build separate appointments at the second-stage. In such a system, we propose and evaluate the staggering appointment policy. Simulation experiments indicate that the proposed staggering appointment policy outperforms other traditional appointment policies in terms of customer waiting time, server idle time, and the number of customers who are later to scheduled appointments.

The waiting time of patients is an important factor related with service quality of a hospital system. An appointment system of patients is not popular, in special, in a private hospital. An appointment system is expected to diversify patients in time and to reduce patient's waiting time. Three appointment rules are suggested and analyzed to compare the waiting time of appointment and walk-in patients using simulation analysis. The results of two way ANOVA show that the time slot of 30 minutes for allocating appointment patients is better than the time slot of 60 minites in view of patient's waiting time. The results of the appointment level 1 also show that the constant pattern rule and the zigzag pattern rule give shorter waiting time for walk-in patient and for appointment patient, respectively.

In today's competitive dental markets, it is of paramount importance to improve service quality and at the same time to use scarce resource efficiently. In this study, we present appointment policies and scheduling rules for private dental clinics to reduce the waiting time of patients and to increase the revenue by utilizing resource more effectively. This study validates the proposed appointment policies and scheduling rules based on simulation models. We show that the bottleneck-based appointment policy is the most effective among appointment policies, followed by the multiple-block appointment one. The shortest processing time among scheduling rules contributes most to the performance of the appointment system.

This study purported to evaluate the performance of the appointment system for outpatients in primary care dental clinic. The data of patients' time flow for 1,245 patients in Y Dental Clinic were collected for one month in 2002 and then analyzed. Specifically, the time periods of treatment and patients' waiting as well as rates of appointment and it's failure are estimated. The accuracy of expected treatment time period was also evaluated. The results showed that 72% of patients visited the clinic with appointments, and only 56% kept their appointments. The patient's waiting time period turned out to be 11 minutes in Y clinic. The expected treatment time period is turned out to be very important because they influence significantly on patient's waiting time period. Practically, the expected treatment time period should be overestimated about 9 minutes in general, and the characteristics of dentist, each patient's diagnosis and age need to be especially considered. Hospitals and clinics also need to make the systematic and detailed critical pathways for a variety of patient cases by analyzing the patients' treatment pattern. With the improved appointment systems, healthcare institutions will approach the goal of effective and efficient management of the institution and also satisfy their customers.

The purpose of this study was to explore factors that physical education graduate students in graduate school of education drop out of teacher appointment examination of secondary school by using Ecological Model. The in-depth interview was conducted for 10 physical education graduate students studying in school of education. As an aspect of the intrapersonal component, the effort to apply how participants'current job positively affects their preparation for teacher appointment examination is required and they need to clearly decide academic priorities to prepare for teacher appointment examination. As an aspect of interpersonal component, participants are negatively affected by subjective norm, thereby providing personalized mentoring program is required. As an aspect of organizational component, limited tuition support and inappropriate place to study are emphasized, so practical helps like sports practice instructor or teacher appointment examination preparation class is required. Finally, this study suggests the introduction of integrated system for teacher appointment examination.

The expanded role of courts in arbitral procedures is said to have certain detrimental effects on the cost-effective approach to arbitration. This is the case when the court is appointing an arbitrator, pursuant to the specific domestic legal regime. The danger of decisions, especially those with expanded role of courts can create delays and hurdles. Even with contradictory viewpoints, the role of the court should complement the arbitral tribunal and not impede the functioning of arbitration independent of the judicial system. In this paper, two recent cases in Korean Supreme Court are reviewed, trying to find the proper implications on further arbitration practices especially in the stage of arbitrator appointment. Even though the proper appointment of arbitrators is essential to the existence of valid arbitration proceedings, appointment of arbitrators by the courts should constitute an administrative power, and not a judicial power. The cases reviewed make clear that the court must play a facilitative role in international commercial arbitration by assisting the parties in appointing the arbitral tribunal, the court intervention must be kept to a minimum.

The role of ICC Court of Arbitration in ICC Arbitration is critical in maintaining the good reputation and worldwide recognition. While most arbitration institutions are the products of regional on national private associations, which play a relatively limited role in appointing or confirming the arbitrators, the Court of Arbitration is not only international in the appointment of arbitrators through the each National Committee, but also intervene in the confirmation of the prospective arbitrators proposed by the parties. Thus the ICC Arbitration is undoubtedly the most highly-supervised form of institutional arbitration available. The purpose of this paper is to examine the appointment and confirmation system of ICC Arbitration, to find the distinctive features of the ICC Rules of Arbitration and to check how to apply the features in the Rules of International Arbitration for the Korean Commercial Arbitration Board(KCAB Rules). Although the KCAB Rules have inherent limitations in the appointment of the arbitrators comparing with the ICC Court. They do not have any confirmation system of the arbitrator proposed by the parties. Although no arbitral institutions is in a position to guarantee completely the ultimate quality and efficacy of the process, the ICC, more than any other institution has historically endeavored to do so through a combination of the efforts of its International Court of Arbitration and National Committees. Composed of legal professionals of more than 75 nationalities, the Court, with the support of its permanent Secretariat in Paris, brings to bear on the decisions that it is responsibility to make the collective and disparate knowledge and experience of a multinational body. Therefore, if the KCAB wants to attract many international disputes, it should try to benchmark the ICC Rules of Arbitration, expecially the Article 9, to secure the prominent arbitrators throughout the world, even though a lot of limitations are exist. The positive role of the ICC Court of Arbitration gives us very important signal.
