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.

The purpose of this study is to survey and analyze of the visitor's cognition of Visitor-Reservation System in Soraksan National Park. To accomplish the purpose, a questionnaire survey was employed in Soraksan National Park. The contents of questionnaire consist of the socioeconomic characteristics and the types of visiting, the activity, the cognition of Visitor-Reservation System. 166 samples of total 170 respondents were used for final analysis. As a result of the analysis, the socioeconomic characteristics and the type of visiting were showed similar trends with results from other National Park visitor survey Most of respondents recognized the enforcement Visitor-Reservation System and A majority of respondents affirmatively recognized the introduction Visitor-Reservation System. Most of respondents wanted an easy method reservation and cancel in enforcement Visitor-Reservation System. Besides Most of respondents recognized negative conception on regulation(nature-rest system, facility-reservation system etc) of National Park Authority(N.P.A). About expanding enforcement Visitor-Reservation System of National Park's preservation, 'Agree Group' was almost equal with 'Disagree Group'. About more effect operate the Visitor-Reservation System Most of respondents were agree to introduce penalty.

The beauty industry has evolved into a highly competitive service sector, expanding alongside economic growth. Nail art, in particular, has witnessed a remarkable surge in popularity. To efficiently manage individual time, nail salons have adopted reservation systems. However, the issue of no-shows, where customers fail to keep their appointments, has emerged as a significant societal and economic concern. This study seeks to identify and address the root causes of no-shows in nail salons, providing essential data for the industry. A comprehensive survey was conducted, involving 476 customers from nail salons in the Daejeon and Chungcheong regions. Survey responses were analyzed using SPSS 24.0 software. Results revealed that a change of mind was the primary reason for no-shows. This underscores the importance of promoting reservation awareness among both businesses and consumers. To mitigate no-shows, suggestions included implementing non-refundable reservation deposits and imposing cancellation fees. Notably, the beauty industry currently lacks systematic regulations concerning no-shows, highlighting the necessity for future research aimed at developing reservation-related guidelines and standards.

A basic concept of TAS(Tractor Appointment System), which not only enhances the terminal productivity, but also yields higher efficiency of domestic CT(Container Terminal), is developed in this paper for CT to more competitive and serviceable. To analyze the effects of TAS when applied to the existing four-tier CT, a quantitative analysis is performed. The results showed that the number of rehandling time of CT has been significantly decreased, the efficiency of CT increased, and the flow time of trucks in CT reduced in a great deal

우리는 RSA 서명에 기반한 효율적인 공정한 예약과 교환 프로토콜을 위해 검증 가능한 암호화를 일반화한 부분적인 검증 가능한 암호화를 제안한다. 부분적인 검증 가능만 암호화를 이용해서 서명에 대한 공정한 교환과 더불어 전자 계약 시 사전 계약이나 비행기 티켓에 대한 예약을 짤 수 있도록 프로토콜을 확장했다. 또한 예약과 교환 시에 공정성을 보장하도록 했다. 이로써 우리는 공정한 교환 프로토콜의 교환단계에서 발생하는 계산 양과 전송 양을 예약과 교환 단계로 분산시키는 효과를 얻었다. 그리고 마지막으로 Ateniese가 제안한 RSA 서명에 기반만 공정한 교완 프로토콜과 성능 비교를 하였다.

Due to the international economic downturn and the increasing competition, container terminals have been trying to achieve cost effectiveness and high service levels. Shipping companies want to get better services from container terminals but container terminals only have limited space and equipment. Frequently, too many external trucks come to the terminal at the same time, and create bottle necks at the terminals. Ouside the container terminals traffic jams occur as well. As a result, stakeholders need a vehicle booking system. By VBS, container terminals can plan efficiently in advance to avoid work delay and the truck drivers can finish their jobs quickly. This paper aims to search efficient models for the container terminals by using VBS.

The objective of this study is to propose a new strategy, called "freeway travel reservation strategy", to mitigate freeway traffic congestion by using advanced traffic technologies and traffic demand management policies, and to analyze its acceptability. Motorist surveys were carried out to accomplish the acceptability analysis. As a result, 73% of respondents agreed with the proposed strategy, and an increase in the inconvenience for using freeway during the major Korean Holidays, in the age, in the number of family members, and in household income resulted in higher acceptability. Additionally, married or female respondents tended to have higher acceptability. Such results can be practical for developing policies to successfully operate the proposed strategy in the future.
