Purpose: This study examines the causal relationship among perceived call center service quality, perceived brand personality, and service loyalty. Methods: This study employs call center services in mobile phone, credit card, and internet shopping, to collect data from respondents via on-line survey, and analyzes causal relationship among above-mentioned three constraints. Results: Perceived call center service quality has a positive impact on perceived brand personality and service loyalty. Perceived brand personality has a positive impact on service loyalty. Cognitive loyalty has a positive influence on attitudinal loyalty. Attitudinal loyalty has a positive impact on behavioral loyalty. Perceived brand personality has a mediating effect towards perceived call center service quality and service loyalty. Conclusion: In order to improve service loyalty, it is necessary to understand diverse variables. Call center service companies are required to find the ways to improve their service quality, while positively applying the techniques of differentiating the brand personality used by manufacturing companies.

This paper is a study on information Quality of Domestic Call Center Information System; recognized the importance of information quality and analyzed the impact on use and satisfaction of users following information quality which is a success element and ultimately the impact on user's performance by expanding information quality evaluating model by Jeong-Woo Lee et al.(2003) who reflected domestic special corporate culture based on information system success model by DeLone and McLean(2003). This is meaningful in providing theoretical foundation for efficient information quality supply and building quality management system at call center in future and provides hints to be considered in raising understanding of consultants on provided information and arranging ground that can utilize it in a timely manner.

Call centers do not simply play a role of responding to customers' calls, but they have developed into a core unit for maintaining competitiveness through services, marketing, or sales. Since the service quality of call centers heavily affects customer satisfaction, organizations have focused on enhancing it by reducing waiting time and increasing service level. One of the techniques, which improve the service quality of call centers, is to employ multi-skilled agents that can handle more than one type of calls. This study deals with three issues relevant to multi-skilled agents. First, we analyze how the way of allocating a specific group of agents to a set of skills affects the performance of call centers. Secondly, we investigate the relationship between the number of multi-skilled agents and the performance of call centers. Finally, we examine the impact of agent selection rules on the performance of call centers. Two selection rules are compared : the first rule is to assign a call to any available agent at random while the other rule is to assign a call preferably to single-skilled agents over multi-skilled agents when applicable. Based on simulation experiments, we suggest three implications. First, as the length of cycles in the agent-skill configuration network becomes longer, call centers achieve higher service level and shorter waiting time. Secondly, simulation results show that as the portion of multi-skilled agents increases, the performance of call centers improves. However, most of the improvement is attained when the portion of multi-skilled agents is relatively low. Finally, the agent selection rules do not significantly affect the call centers' performance, but the rule of preferring single-skilled agents tends to distribute the workload among agents more equally.

공적불평행동에서 회사에 대한 직접 불평을 하고, 배상을 요구하는 경우가 빈번하게 나타나고 있는 현 상황에서 콜센터의 대응은 매우 중요한 시점이다. 본 연구의 목적은 콜센터의 서비스품질차원과 세부요인을 찾아내고, 서비스품질차원이 서비스회복, 고객충성도와 어떠한 관련성이 있는지를 연구하는 것이다. 불만족을 경험한 조사대상자 139명을 대상으로 콜센타 서비스품질과 고객충성도 관계성을 검증하기 위해서 가설과 연구모형을 설정하였다. 가설 검증 결과 3개의 콜센타 상담원 서비스 품질과 서비스 회복에 정에 영향을 미치는 것으로 나타났다. 서비스회복은 고객충성도에 정에 영향을 미치는 것으로 나타났다. 결과품질은 상담후의 고객한테 남는 결과물로서 고객의 입장에서 보면 콜센터 이용의 궁극적인 목적이라고 할 수 있으며, 조사 결과 콜센터 서비스품질 세 가지 차원 중 서비스회복에 미치는 영향력이 가장 큰 것으로 드러났다. 서비스회복과 고객충성도 간의 관계에서 서비스회복은 고객충성도에 유의한 영향을 미치는 것으로 나타났다. 콜센터에서는 서비스회복을 도모하고 고객의 고객만족도 및 충성도를 높이기 위하여 콜센터 서비스품질의 관리가 필요하다.

The purpose of this paper is to test whether prices of mobile communication service reflect their varying degrees of call quality, controlling for other service attributes. As, in fact, service is intangible goods difficult to measure its value, this paper makes use of econometric model, hedonic price analysis. Hedonic price analysis, has ever been applied in public or environmental economics, is employed and produces estimates of the prices (or the contributions toward the total price) for each characteristic. This paper applied hedonic technique to the value measurement of a service property for the use of Korean mobile communication. This paper uses actual transaction prices of mobile communication service to determine whether or not the market functions in pricing call quality of mobile communication service. Finally, this show that the willingness to pay of consumer increases as call quality increases and so market makes prices on call qualities. Thus, major concern in this paper is about value measurement o service quality, and also suggest of the possibility to determine call quality value (or price) of mobile communication service.

Objectives: The purpose of this study is to figure out that Facilitation education can affect significant improvement in sales staff's understanding of precise pharmacokinetics, benefits, safety, and side effects, etc. and eventually lead to increase in call after taking courses. Methods: Data utilized in this study was collected from 413 sales staffs who completed Facilitation course for 5 months. This study used statistical methodologies, paired t-test, exploratory factor analysis, and logistic regression model in order to identify change in Call and after Facilitation courses. Results: The result shows that there are statistically significant increases in CALL quality after Facilitation courses based on the result of pared t-test. Moreover, Facilitation education is more effective in average time of one-time detail than average number of visits per day and average number of doctors per day from the result of logistic regression. Conclusions: In order for MR in pharmaceutical company to improve CALL quality, the education for precise pharmacokinetics, benefits, safety, and side effects is necessary. In addition, various professional training required for detail, including disease education, Selling Skills education, and literacy education are essential. Therefore, Facilitation education would be desirable choice in terms of pharmaceutical marketing strategy.

Provisioning of quality of service (QoS) is a key issue in any multi-media system. However, in wireless systems, supporting QoS requirements of different traffic types is a more challenging problem due to the need to simultaneously minimize two performance metrics - the probability of dropping a handover call and the probability of blocking a new call. Since QoS requirements are not as stringent for non-real-time traffic, as opposed to real-time traffic, more calls can be accommodated by releasing some bandwidth from the already admitted non-real-time traffic calls. If the released bandwidth that is used to handle handover calls is larger than the released bandwidth that is used for new calls, then the resulting probability of dropping a handover call is smaller than the probability of blocking a new call. In this paper, we propose an efficient call admission control algorithm that relies on adaptive multi-level bandwidth-allocation scheme for non-realtime calls. The scheme allows reduction of the call dropping probability, along with an increase in the bandwidth utilization. The numerical results show that the proposed scheme is capable of attaining negligible handover call dropping probability without sacrificing bandwidth utilization.

본 논문에서 역방향 DS-CDMA(Direct Sequence-Code Division Multiple Access)에서 요구하는 QoS(Quality of Services)를 보장하기 위한 호 수락 제어를 제안한다 물리적 채널수에 의한 방법과 MODEM (modulator/ demodulator)부분으로부터 수신된 신호의 품질에 기반한 방법이 이미 연구되어졌다. 다른 방법으로, BTS(Base Transceiver Station)에서 수신된 파워 레벨을 사용한 방법과 사용자들의 위치를 통계적으로 분석한 방법으로 그 기준을 정하기도 한다. 이러한 방법들은 시스템의 과부하를 가져올 뿐만 아니라 시간 지연 또는 실제 환경에 적용하는데 큰 어려움이 있다. 이러한 문제를 풀기 위해, 실시간으로 BTS부분의 LNA(Low Noise Amplifier)에서 측정한 값을 기반으로 호 수락 제어를 목적으로 호 절단 추정을 제안한다. 본 논문에서 이러한 방법의 제안은 실시간에서 제공하는 서비스의 품질을 추정하고, 시스템의 부하를 줄이며, 짧은 시간지연을 가질 수 있다. 그러나 BTS에서 호 절단 률을 측정하고 수신 신호의 전력을 측정하기 위해 BTS에서 하드웨어 복잡성이 더해진다.
