이번 연구는 실제 기업 자료를 기반으로 고객보상 프로그램이 고객 유지(retention)에 미치는 영향을 살펴보았다. 특히 고객보상 프로그램의 효과를 보다 명확히 확인하기 위해 유사실험설계(quasi-experimental design)를 사용하였다. 그리고 1년이 넘는 장기적인 시간 프레임 속에서 고객보상 프로그램의 도입 시점을 전후로 소비자 집단을 구분하고 이들 집단의 비교를 통해 고객보상 프로그램의 효과를 파악하였다. 이러한 연구 설계를 고려한 이유는 종적 자료를 사용한 선행 연구들이 고객보상 프로그램의 도입 시점 이후부터 가입 고객과 비가입 고객을 대상으로 프로그램의 효과를 측정하였기 때문에 자기선택오류(self-selection bias)의 가능성이 존재하였기 때문이다. 이번 연구는 고객보상 프로그램의 도입 시점을 전후로 두 집단을 비교하기 위해 자료를 특정 시점을 기준으로 절단(censoring)하였다. 생존분석(survival analysis)은 다른 분석기법에 비해 불완전한 자료가 포함되더라도 분석이 상대적으로 용이하므로 이번 연구의 분석방법으로 선택하였다. 분석 결과 고객보상 프로그램을 실시하기 전에는 소비자들의 거래기간이 평균 179일이었으나 고객보상 프로그램을 도입한 이후에는 227일로 약 50일 정도 더 늘어났다. 이러한 차이는 통계적으로 유의한 것으로 나타나 연구 가설을 지지하였다. 또한 콕스 비례위험모형을 사용하여 고객보상 프로그램과 영향 변수들의 상호작용효과를 확인한 결과 기존고객들은 고객보상 프로그램이 도입된 후 신규고객들에 비해 회사와의 거래기간이 유의하게 증가한 것으로 나타났으며 긍정적인 서비스(예: 30일 이내 입회)를 경험한 고객들도 회사와의 거래기간이 유의하게 증가하는 것으로 나타났다. 한편 부정적인 서비스(예: 30일 이후 입회)를 경험한 고객이라 하더라도 고객보상 프로그램을 도입한 이후에는 회사와의 거래기간이 증가하였다. 이번 연구에서 나타난 결과들을 정리하면 고객보상 프로그램은 고객과 긍정적인 관계를 형성하는 데 기여할 뿐만 아니라 이탈 장벽까지 구축해 줌으로써 기업의 경쟁력을 강화시키는 수단으로서의 가치가 있다고 생각할 수 있다.

The Dynamic Adaptive Streaming over HTTP(DASH) is envisioned to evolve to meet an increasing demand on providing seamless video streaming services in the near future. The DASH performance heavily depends on the client's adaptive quality selection algorithm that is not included in the standard. The existing conventional algorithms are basically based on a procedural algorithm that is not easy to capture and reflect all variations of dynamic network and traffic conditions in a variety of network environments. To solve this problem, this paper proposes a novel quality selection mechanism based on the Deep Q-Network(DQN) model, the DQN-based DASH Adaptive Bitrate(ABR) mechanism. The proposed mechanism adopts a new reward calculation method based on five major performance metrics to reflect the current conditions of networks and devices in real time. In addition, the size of the consecutive video segment to be downloaded is also considered as a major learning metric to reflect a variety of video encodings. Experimental results show that the proposed mechanism quickly selects a suitable video quality even in high error rate environments, significantly reducing frequency of quality changes compared to the existing algorithm and simultaneously improving average video quality during video playback.

This study examined effect of preceptorship on clinical education of 39 senior nursing students. Competency scores and satisfaction with preceptors scores were investigated. Competency scores of the students before the clinical education (pre-competency scores) were compared with the competency scores after the clinical education (post-competency scores), and satisfactory scores were also examined after the clinical education. Study results showed that the total post-competency scores were increased compared to the total pre-competency scores, and this increment was statistically significant. However, analyzing sub-domains of the competency scores indicated only the nursing-skill domain scores were increased while the scores of interpersonal domain and management domain were increased but statistically insignificant. Satisfaction with preceptors scores were also more than the average scores reflecting the students were satisfied with their preceptors generally. The students, However, grade low in the preceptors' intellectual ability while their professional and interpersonal ability were rather satisfied. This study indicated preceptors should make more efforts to teach interpersonal and management skill and increase their intellectual ability. This study recommended a systematic reward system for the preceptors to increase the motivation to teach students is needed.
