Gamers switch their games to a new when get bored or encounter more attractive ones. Switching cost varies by gamers and depends on how they are satisfied with their current game. This study evaluates the satisfaction with current games as the miltiple basic psychological need in the self-determination theory and suggests 'needs-costs' causality research model that explain the variety of gamer's switching behavior. As the empirical test to domestic mobile gamers, the autonomy fulfillment to current game affect reversely with those of autonomy and relatedness. Those relationships between need satisfaction and perceptual switching cost vary according to their age and game genre preference. The results would be applied to understand gamers' switching behavior.

The most expensive spatial operation in patial database in a spatial join which computes a combined table of which tuple consists of two tuples of the two tables satisgying a spatial predicate. Although the execution time of sequential processing of a spatial join has been so far considerably improved the response time is not tolerable because of not meeting the requiremetns of interactive users. It is usually appropriate to use parallel processing to improve the performance of spatial join processing. in spatial database the fixed grids which consist of the regularly partitioned cells can be employed the previous works on the spatial joins have not studied the parallel processing of spatial joins using fixed grids. This paper has presented an analytical cost model that estimates the comparative performance of a parallel spatial join algorithm based on the fixed grids in terms of the number of MBR comparisons. disk accesses, and message passing, Several experiments on the synthetic and real datasets show that the proposed analytical model is very accurate. This most model is also expected to used for implementing a very important DBMS component, Called the query processing optimizer.

This study conducted a survey on visitors who visited the 2021-2022 KBL Professional Basketball Stadium in Wonju to understand how professional sports viewing factors affect the club image, club satisfaction, and club reputation. As factors for watching professional sports, four factors were considered: stadium, game situation, spectating cost, and spectator promotion. A total of 450 questionnaires were distributed and 411 questionnaires excluding 39 questionnaires were used as the final analysis data. For the effective questionnaire survey, After analyzing the purpose and purpose of the research, participants were asked to collect data. The collected data were analyzed using SPSS statistical package after data coding and cleaning process. The results of this study are as follows. First, the effect of professional sports viewing factor on brand image was 45.1%, and the factor of pro sports viewing was significant in stadium, competition situation, and promotion of viewing, and had no effect on viewing cost. Second, the influence of professional sporting factor on the satisfaction of the team was 42.5% in explaining power, which was significant in the stadium, the competition situation, the cost of visiting, and promotion of viewing. Third, the influence of professional sports viewing factor on team reputation was 62.1%, and the factor of professional sports viewing was significant in promoting stadium, visiting cost, and viewing, and had no effect on economic situation. The implication of this study is that in order to increase the brand value of the club, it is much more effective to increase the quality of facilities and food and beverages and to activate events for the audience than to lower the cost of viewing.

The main purpose of this study is to conceptualize and investigate the relationships between the antecedents and outcomes of customer satisfaction and the linking variables of brand preference and repurchase intention in service industries. To achieve this objective, the study tries to validate the structural equation model and causal relationships among the model's elements involving antecedents to customer satisfaction(perceived quality, value, equity), consequences(brand preference, repurchase intention), and moderating variable/switching cost, customer loyalty). Empirical findings are as follows: First, the effect of two antecedents/perceived quality and value) on customer. satisfaction was accepted but perceived equity was rejected. Second, I found out that there were direct or indirect relationships between the mediating variables/switching cost, customer loyalty, brand preference) and repurchase intention. This means that the proper management concerned with indirect path is probably more important for the success of services industries. Third, the direct effects of customer satisfaction and switching cost on repurchase intention were not significant against the existing studies excepting brand preference. This implies that repurchase intention was mainly intensified by the indirect path, 'customer loyalty${\rightarrow}$brand preference${\rightarrow}$repurchase intention' and 'switching cost${\rightarrow}$brand preference${\rightarrow}$repurchase intention.' The service marketers make efforts not only to strengthen the direct casual linkage but also to consolidate the indirect connections leading to create repurchase intention. Finally, the proper management of these structural relationships will help clarify the role of service marketer resulting in increasing sustainable competitive advantage in service industries.

최근 클라우드 컴퓨팅에 관련된 기술이 각광을 받으면서, 기존에 인터넷을 통해 제공되던 다양한 서비스들이 클라우드 컴퓨팅 플랫폼 환경으로 이동하고 있다. 이를 통해 사용자들에게는 좀 더 편리하고 유연한 서비스를 제공하고 서비스 제공자들에게는 기존 관리 비용의 절감을 할 수 있게 되었고 이러한 변화는 새로운 컴퓨팅 환경 패러다임으로의 급속한 전환을 가져오게 되었다. 하지만 현재 폭발적인 수요의 증가로 인해, 기존의 자원 활용도의 극대화를 목적으로 고안된 자원 분배 기법들에 대한 여러 한계점이 나타나게 되었다. 본 논문에서는 이러한 문제점들을 해결하고자 클라우드 컴퓨팅 환경에서 SLA을 기반으로 사용자나 서비스 제공자의 비용적인 측면을 고려한 자원분배를 통해 서비스를 제공시 사용자 요구를 만족시키고 동시에 서비스 공급자에게는 비용 효율적인 프로비저닝(Provisioning) 기법을 제안하고자 한다. 실험 결과 기존의 자원 활용도에 중점을 둔 기법보다 사용자 요청에 대한 응답 속도가 8.46% 향상되었으며, 컴퓨터 자원 유지 관련 비용면에서도 14.35%정도 절감 효과를 가져오는 것을 확인 할 수 있었다.
