본 논문에서는 다중클래스 통신망을 위한 새로운 과금 (pricing) 기반의 호수락 제어 (call admission control) 알고리즘 제안한다. 본 알고리즘에서는 통신망에 새롭게 호가 도착하게 되면, 요청 회선의 수와 필요로 하는 최소 시간을 통신망에 알려준다. 통신망은 기대 수익 (expected revenue)을 최대화하는 최적의 과금을 계산하여 호에 제안한다. 이때, 최적 과금은 도착한 호의 정보와 현재 그리고 미래에 추정되는 호 예약시간 동안의 망내 정체(congestion) 정도를 기반으로 동적으로 조정된다. 호가 제안된 과금을 수락하면 호는 연결이 되고 그렇지 않으면 연결이 되지 않는다. 본 논문에서는 제안된 동적 과금 기반 호수락 제어 알고리즘의 성능을 Courcoubetis와 Reiman[1] 그리고 Paschalidis와 Tsitsiklis [2]의 정적 과금 기반 호수락 제어 알고리즘의 성능과 비교한다. 비록 두 알고리즘은 거의 같은 수익 결과를 보이지만, 동적 알고리즘이 정적 알고리즘에 비해 더 높은 호 수락율과 각 호에 낮은 과금을 제안하는 측면에서 더 뛰어난 성능을 나타냄을 보인다. 이는 경쟁 상황에서 정적 가격 알고리즘에 비해 동적 가격 알고리즘이 더 많은 사용자를 끌어들여 수익을 더 낼 수 있음을 의미하며 더 나아가 접속 요금이 과금에 고려된다면, 동적 과금 호수락 제어 알고리즘이 더 많은 수익을 낼 수 있음을 보인다.

Svg는 2차원 그래픽을 표현하기 위해 xml을 기반으로 만들어진 언어로서 W3C에 의한 xml 그래픽 표준이다. Xml의 개방성과 상호운용성 등의 장점을 모두 수용하여 다른 xml 언어들과 결합시켜 다양한 웹 어플리케이션으로 응용 할 수 있다. 실시간 데이터로부터 고품질의 다이나믹한 그래픽을 만들어 낼 수 있기 때문에 전자상거래, 지리정보, 교육과 광고 등의 분야에 적용 될 수 있다. 데이터베이스와의 연동으로 SVG의 응용을 더 높일 수 있다. 이는 단지 사용자 측면에서의 어플리케이션이 아닌 서비스를 제공하는 서버와의 대화가 가능하다는 것이다. 이 논문에서는 svg의 의미나 능력을 설명하는 것이 아니라 실제 극장 시스템에서 어떻게 활용 될 수 있는지를 말해 줄 것이다. svg는 xml의 장점에 그래픽적인 장점을 더 한 것이다. 이 말은 단지 svg가 그래픽적인 요소만이 아닌 xml의 유연성을 가졌다는 말이 된다. 실제 좌석의 위치지정과 새로운 좌석의 추가가 쉽다. 그룹으로 지정된 좌석은 단지 태그의 추가만으로 좌석을 생성할 수 있다. 이는 좌석의 변화와 또는 좌석의 고장 시 즉시 svg에 나타낼 수가 있다. 또한 svg는 데이터베이스와의 연동이 가능하고 추가 수정이 쉽다. 이는 벡터의 데이터를 갔고 있어서 가능한 것이다. 기존의 예약 시스템은 표를 살 때 시간과 가격의 정보만 있었지만, svg로 구현할 경우 좌석의 위치와 가격, 그리고 구매여부, 취소 등을 눈으로 보면서 할 수 있다.

Purpose - As more low cost carriers are introduced, the competition between the low cost carriers to become the nation's leading low cost carrier is also being intensified. The purpose of this study is to select various choice attributes for low cost carrier and figure out important factors that customers take into account for low cost carrier selection. The study also involves in establishing the relationship between perceived value, customer satisfaction, and customer behavior Intention, in an effort to identify choice attributes that are important to customers' low cost carrier. Research design, data, and methodology - To examine these research models, samples were collected from 247 peoples who visited In-Cheon international Airport during June, 2017. Results - The results of the study showed that, 'reservation service', 'airport service', 'in-flight service', and 'price' services have a significant effect on the perceived value of the choice attributes. While 'reservation service', 'airport service', 'in-flight service', and 'flight operation service' have a significant effect on the customer satisfaction of the choice attributes, perceived value has a significant effect on customer satisfaction. Perceived value has a significant effect on customer behavior intention. Finally, customer satisfaction has a significant effect on customer behavior intention. Conclusions - Flight operation service has no significant effect on perceived value of the choice attributes of low cost carriers, which indicates that the low cost carriers have not yet been well-established in the flight operation service sector. It seems likely that low cost carrier will be able to gain a competitive advantage over other companies if they expand their routes and improve the convenience of flight connections. In addition, the results show that the price service does not have a significant effect on customer satisfaction of the choice attributes of low cost carriers. From this, we may assume that the airline ticket prices of low cost carriers are already low, and the price cannot be a deciding factor in the competitive advantage of low cost carriers. To achieve higher customer satisfaction of the choice attributes, companies should strengthen the competitiveness of 'reservation service', 'airport service', 'in-flight service', and 'flight operation service'.

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.

This study identified how family restaurant customers' attitude toward yield management strategies, which include reservation, time, menu, and service factors. Generally, yield management explains how price and dining duration maximize the revenue of family restaurants. There are three ways to improve family restaurant yield; improving table turns, upgrading seat occupancy, increasing price per customer. The 45 items of yield management strategies are developed by literature reviews, web sites analysis, and interviews with family restaurant employers. Factor analysis and reliability analysis from present study found out 11 important factors, which represent the study's dependent variables. Regression analysis may be helpful to test whether demographic and socio-economic factors have relationships with family restaurant customers' attitude toward yield management strategies. As a regression result, gender, family size, age in demographic factors and education and occupation in socio-economic factors have relationships with family restaurant customers' attitude toward yield management strategies significantly.

To evaluate customer satisfaction of hotel food and beverage products, developing items for the measurement is necessary through studying the properties of food and beverage products. The properties consist of human service, physical and systematic service. Human service includes appearance and uniforms, courtesy and kindness, quickness and precision of the service, well-educatedness, moral sense and etc. Physical service includes the taste of food and beverage, diversity of food and beverage, outlets' cleanness and atmosphere, refinement of fixture, furnishing and table ware, the admission passage to the hotel and parking lot facilities, and etc. Systematic service includes passages of movement to outlet, arrangement of outlet, reservation management system, operation of events and package goods, temperature and ventilation system and etc. The price is also one of important variables to measure customer satisfaction index, so it is included to the investigating items. As shown some hotels have several satisfactory items but most items are unsatisfactory because expected service is better than perceived service. Therefore, the hotels which lack human service need the reinforcement of service education, the hotels which lack physical and systematic services need the improvement, the development and the renovation according to the unsatisfactory items. And the hotels whose price item is unsatisfactory need to consider the policy.

The purpose of this study is to discovered assessment items for improving athletic efficiency and management of golf courses. Through this, the study intended to provide basic data for creating competitive golf courses and management. Important assessment items were selected by inducing preliminary assessment items and conducting a preliminary survey and a main survey for specialists through a theoretical study. For the survey results studied, reliability and average value for importance were calculated using SPSS/PC Window Release 12.0. As assessment of importance by assessment area, in athletic efficiency assessment, course management level was the highest, followed by fairness of games and operation of games. In management assessment, importance of service level, information management, facility management, management of game assistants, etc. were high. As assessment of importance by assessment item, it was found that 'variety of golf shot' and 'the length of a course' were important in course layout. Also 'start interval among teams' and 'disturbance of play' were assessed as important items in game operation, while 'fair reservation' and 'rounding rotation time' were important in fairness of games. In addition, in information management, 'kind service of golf course staffs' and 'prompt reservation and notification' were found to be important assessment items. In facility management, all assessment indexes were over 4.0, which means all of them are important for quality of golf course and competitiveness. In membership service, 'appropriate price of goods for sale' and 'service for members' were relatively important assessment items. Further, in management of game assistants, 'qualifications and skillfulness of game assistants' was assessed as a very important index. Although the current study only selected important items to assess excellent golf courses, it is necessary to apply the study results to the actual sites and verify them for golf course both at domestic and abroad.

On the basis of 2017, the cremation rate in capital area was 89.0% which was much higher than the national average cremation rate(84.6%). Due to the short supply of cremation facilities in accordance with the increased number of cremation cases every year, the demand for cremation from the residents outside of the jurisdiction area with no cremation facilities was increased, so that the residents in the jurisdiction area had difficulties in using the Online Cremation Reservation Service in Funeral Information System. Thus, this study aims to make suggestions for policies as follows.First, on the basis of 2017, the demand-supply rate of cremation facilities in Gyeonggi-do was 139.4%, which means that the demand for cremation largely exceeds the ability to supply cremation. Therefore, first, in the level of Gyeonggi-do, the expanded supply of cremation facilities should be induced by carrying forward policies such as financial support to the basic local governments installing cremation facilities and expansion of incentives support to the residents of regions attracting cremation facilities. Second, it would be necessary for the central government to expansively conduct the support standard price and government subsidy rate(70%) for the new construction of cremation facilities and the establishment of cremation furnaces. Third, there should be some policies to decrease the inflow of residents outside of the jurisdiction area by raising the fee for using cremation facilities outside of the jurisdiction area of Seoul Metropolitan City and also expanding the application of a sliding scale of cremation hours.
