The purpose of this study is to suggest a research for hotels' expected service quality which influences reservation intention of hotel services. And we checked that these relations are formed by mediating of customer value on the basis of temporal construal theory. The result of our studies is as follows: 1) An abstract hotels' expected service quality(a concrete hotels' expected service quality) influence more on the customer's the social psychological value(the functional value) than the functional value(the social psychological value). 2) The customer's functional value(the social psychological value) influence more on the reservation intention of hotel service near(distant) in time than distant(near) in time. This research provides a theoretical-practical implications to the marketing staffs like packaging designers as well as scholars to study hotel services.

By committing to a long-term replenishment contract, suppliers can mitigate the pressure to find new customers and afford to charge a discounted price to buyers seeking to lower their purchasing costs. In this paper, we develop an analytical model from buyer's perspective for the contracting process to investigate the buyer-supplier interactions. Based on the developed model, we propose an algorithm to derive optimal strategy for the contract. We consider a system with a single buyer and a supplier in a situation where the buyer's inventory is controlled by (R, S) policy under VMI setting. According to the contract, the supplier should replenish the buyer's inventory up to a fixed level every R times during a specified period. The buyer purchases any deficient amount from a spot market at a higher price. We show by computational experiment that our proposed algorithm finds the global optimum solution.

주문형 비디오 시스템의 성능에서 중요한 문제는 클라이언트 요구를 만족시키기 위한 입출력 대역폭이다. 이러한 입출력 대역폭을 감소시키기 위해 하나의 비디오 스트림을 사용하여 다중 요청을 처리하는 많은 정책들; 배칭. 피기백 머징, 버퍼링이 연구되고 있다. 본 논문에서는 인기 있는 비디오들에 대한 서비스 요청들이 매 배칭 간격마다 스케줄될 수 있도록 인기 있는 비디오들을 위한 서버 스트림 용량을 동적으로 예약해 두는 예약 기반 동적 배칭 정책을 제안하고, 그것의 성능을 시뮬레이션을 통하여 단순 배칭 정책과 비교하고 평가한다.

인터넷의 발달로 인하여 기존 전화망을 인터넷 망으로 적은 비용으로 사용하고자 VoIP 가 연구되기 시작하였다. VoIP 의 기존전화망과의 품질의 차이에도 불구하고 대폭적인 통화비용의 절감과 다양한 이점으로 많은 연구가 되고 있다. 이에 통화품질의 향상을 위하여 QoS에 대한 연구가 활발히 진행되고 있다. 여기서는 QoS를 지원하는 Q-SIP 서버와 Policy Based 의 COPS 를 이용하여 Pre-COPS update message 와 Reservation COPS cache로 정책결정과 QoS를 지원하고자 한다.

Underwater acoustic sensor networks can be used disaster prevention and environmental monitoring systems in underwater environments. Because, the underwater environment is different from the ground, the long propagation delay, low transfer rates and limited bandwidth characteristics should be considered. In this, paper will propose the MAC protocol that allocates time slot into each node according to priority policy through the period of contention-free slot reservation in underwater acoustic sensor networks in order to avoid collision and minimize energy consumption waste. We perform mathematical analysis to evaluate the performance of the proposed protocol with regard to the collision probability, the energy consumption by collision, throughput and channel utilization. We compare the proposed protocol with the conventional protocol, and the performance results show that the proposed protocol outperforms the conventional protocol.

This article has tried to analyse the effect of the corporate earning return tax empirically through analysis on the impact of previous internal reservation on the dividends rate of the current year. In addition to this, this article has tried to the effectiveness of government policies with leverage ratio as a moderating variable. Moreover, DRF and GBM model were used to see the effect again. As a result of the actual proof analysis, OCF, ROE, FOR have a significance level of 99% in model1, model2, model3. However, ADV and MSE has appeared not to be meaningful in all models. In the result of DRF and GBM model for convergence was higher than GBM in depth and leaves. However, when it comes to a model explaining capability, GBM high than DRF. The further study will be required to examine the effect of government policy by time series analysis in the period of enforcement of the reflux tax, from 2015 to 2017.

This paper aims to design and realize mobile webapp ticket reservation system based smartphone with N-tier mobile webapp framework. In mobile framework, presentation-tier utilizes HTML5/CSS3 and Sencha Touch, middle-tier consists of spring framework and MyBatis, database-tier using oracle possible to apply enterprise services mobile webbapp offices. In this study, mobile framework deploy and configuration management without the support of the app in N-tier that does not need to be considered in the smartphone-based mobile webapp ticket reservation system analysis and design, and then implementation.

As of 2016, Incheon Metropolitan City's cremation ratio was 91.2%, which is the second highest among all metropolitan municipalities nationwide (Busan Metropolitan City: 92.0%). In addition, the number of cremation at the outside of the jurisdiction has been steadily increasing since 2014. It is analyzed that the number of cremation at the inside of the jurisdiction is 16,004, which is 67.3% of total number of cremation, and the number of cremation at the outside of the jurisdiction is 7,779, which is 32.7%. We would like to suggest the following policy suggestions to solve the problems caused by the increase in cremation demand. First, the number of operations of cremation in public facilities located in Gyeonggi-do adjacent to Incheon Metropolitan City is needed to be increased. Second, the extension of the time limit for the use of cremation facilities of the dead people at the outside of the jurisdiction is needed. Third, the charge for cremation at the outside of the jurisdiction has to be increased. Fourth, improvement measures such as relaxation of residency requirements for deaths at the inside of the jurisdiction, who used the public facilities in Incheon Metropolitan City, should be undertaken.

This paper intends to suggest methods to design and implement a jQuery mobile based system in a future mobile webapp environment through a study on an N-Screen application in a mobile webapp. N-Screen is one of the representative services of cloud computing. It is promoted by the need of users to require universal functions for all devices. However, this situation is in conflict with the users' need to have the same experience and N-Screen cannot deal with these disparate services. Thus, this study intends to suggest a system analysis, structure of design, and a framework by implementing the N-Screen based movie reservation system in the jQuery mobile environment.

The Influences of the Ecotourism Motive, on the Attitude, Resource Interpretation and Satisfaction of Tourist Ecotourism has been recently introduced to maintain the relation of mutual dependence between the tourism and the natural environment. However it is adversely used and creates the destruction of ecosystem. It is Important that the ecotourism is a tourism which tourists can experience and enjoy themselves on site rather than a tourism which they only see and hear, understand. It is assumed that a method should be found to maximize toursist' satisfaction and that the presentation of interpretation of the tourism resource may satisfy the tourist's satisfaction. The results offer the suggestion points as follows. 1. By providing the interpretation of tourism resource as well as the recreational object, the ecotourism can be activated with a sound recognition of nature and the reservation of environment, and furthermore, the development policy may be based on not only the area of ecotourism but also all of the tour area. 2. By providing the interpretation service of tourism resource for tourists, the satisfaction can be maximized by the high cognition of tourist. 3. By providing the information about the tourism destination and resource, it will contribute to the side of education, it will contribute the preservation of resource and the reservation of environment. Ecotourism, Tourism Motive, Tourism Attitude, Tourism Resource Interpretation Tourist Satisfaction.
