Covid-19로 인해 비대면 수업이 지속되고 있다. 과거부터 e-러닝 수업은 있었지만 코로나로 인한 비대면 수업은 실시간 수업과 녹화수업이 결합되거나 대면과 비대면이 결합된 블랜디드(blended) 수업이라는 것이 차이점이다. 또한 전용 스튜디오가 아닌 곳에서 자가 촬영하거나 다양한 강의 플랫폼을 선택할 수 있다는 점이 특징이다. 비대면 수업의 이점은 시간과 공간을 초월하여 학습할 수 있고, 반복 시청, 학습속도를 조절할 수 있다. 녹화수업은 시간과 장소적 제약이 없지만, 실시간 수업은 시간적 제약은 있지만, 학습자와의 커뮤니케이션 효과가 높다는 장점이 있다. 비대면 수업이 대면수업이나 e-러닝과 비교하여 충분한 품질을 제공하는지를 평가하는 일은 포스트 코로나 이후에도 블렌디드 수업을 고려한다면 필요한 일이 될 것이다. 본 논문에서는 비대면 수업의 서비스 품질평가를 위해 Kano 품질속성 관점에서 학습자들이 원하는 필수속성을 도출하고 품질개선 방안을 제안하였다. 비대면 수업이 갖추어야 할 기능의 정도를 X축, 학습자의 만족도를 Y축으로 나타낸 후 23개의 품질속성을 6개로 분류하였다. 그리고 만족계수, 불만족 계수, 고객만족개선지수를 도출하였다. 학습자들의 50%가 비대면 수업에 만족했지만 선호도는 만족도 보다는 약간 높게 나타나 비대면 수업의 지속 가능성을 암시하고 있다. 고객만족개선 지수로 볼 때, 수업 품질을 개선했을 때 만족도 증가폭이 가장 큰 속성들은 학습자의 질문에 대한 교수의 신속한 답변, 교과내용을 반영한 충실한 강의 콘텐츠, 교수가 알기 쉽게 설명해 주는 것, 모바일 폰에서도 학습할 수 있는 고품질의 콘텐츠 개발, 출석체크의 공정성, 그리고 실시간 수업은 정시에 수업 시작 순이었다.

Purpose: The salesperson, the core of the operating activities, plays the role of connecting the inside and outside of the company, representing the company to the consumer and identifying and responding to the customer's needs. The department store industry is the most representative retail industry in South Korea, and competition among its peer group and industry is intensifying, requiring differentiated service sales activities and performance from its employees. This study divided the sales force system into activity control(process-oriented control) and output control(performance-oriented control) and verified the differential impact on the job attitude of the salesperson (e.g., job satisfaction and burn-out), respectively. In addition, the effect of job satisfaction and burn-out of the salesperson on the job performance were checked. Research design, data, and methodology: The survey was conducted on 200 sales people working at five branch stores of Hyundai department store in Seoul, and 194 of them were analyzed. The reliability and validity of the variables were analyzed and hypotheses were verified through the SEM. Results: Results have shown that activity control has a greater impact on burn-out compared to output control, and output control has a greater impact on job satisfaction compared to activity control. It has been shown that the salesperson's burn-out does not affect sales performance, but that job satisfaction has a positive effect on sales performance. Conclusions: This study examines the effect of sales force management system such as activity control and output control, on the job attitude and sales performance in department stores. According to the results of this research, each of two control systems have a discriminatory effect on the job attitude variables. For the sales managers of department store, it is recommended to increase the efficiency of sales management by increasing the use of outcome control compared to activity control.

Determining relative importance among many quality attributes under financial constraints is an important task. The weighted value of an attribute particularly in QFD, will influence on engineering characteristics and this will eventually influence the whole manufacturing process such as parts deployment, process planning, and production planning. Several scholars have suggested weighting formulas using CSC (Customer Satisfaction Coefficient) in the Kano model. However, previous research shows that the validity of the CSC approaches has not been proved systematically. The aim of the present study is to address drawbacks of CSC and to develop APC (Average Potential Coefficient), a new approach for weighting of quality attributes. For this, the current study investigated 33 quality attributes of e-learning and conducted a survey of 375 university students for the results of APC, the Kano model, and the direct importance of the quality attributes. The results show that the proposed APC is better than other approaches based on the correlation analysis with the results of direct importance. An analysis of e-leaning's quality perceptions using the Kano model and suggestions for improving e-learning's service quality are also included in this study.

전자상거래 시장의 이용이 보편화 되며 고객들에게 좋은 품질의 물건을 어디서, 얼마나 합리적으로 구매할 수 있는지가 중요해졌다. 이러한 구매 심리의 변화는 방대한 정보 속에서 오히려 고객들의 구매 의사결정을 어렵게 만드는 경향이 있다. 이때 추천 시스템은 고객의 구매 행동을 분석하여 정보 검색에 드는 비용을 줄이고 만족도를 높이는 효과가 있다. 하지만 대부분 추천 시스템은 책이나 영화 등 동종 상품 분류 내에서만 추천이 이뤄진다. 왜냐하면 추천 시스템은 특정 상품에 매긴 구매 평점 데이터를 기반으로 해당 상품 분류 내 유사한 상품에 대한 구매 만족도를 추정하기 때문이다. 그밖에 추천 시스템에서 사용하는 구매 평점의 신뢰성에 대한 문제도 제시되고 있으며 오프라인에선 평점 확보 자체가 어렵다. 이에 본 연구에서는 일련의 문제를 개선하기 위해 RFM 다차원 분석 기법을 활용하여 기존에 사용하던 고객의 구매 평점을 객관적으로 대체할 수 있는 새로운 지표의 활용 가능성을 제안하는 바이다. 실제 기업의 구매 이력 데이터에 해당 지표를 적용해서 검증해본 결과 높게는 약 55%에 해당하는 정확도를 기록했다. 이는 총 4,386종에 달하는 이종 상품들 중 한번도 이용해 본 적 없는 상품을 추천한 결과이기 때문에 검증 결과는 상대적으로 높은 정확도와 활용가치를 의미한다. 그리고 본 연구는 오프라인의 다양한 상품데이터에서도 적용할 수 있는 범용적인 추천 시스템의 가능성을 시사한다. 향후 추가적인 데이터를 확보한다면 제안하는 추천 시스템의 정확도 향상도 기대할 수 있다.

This paper investigated main determinants of purchase intention for VOD contents by employing an extended technology acceptance model. The findings showed that 'user activeness' is the critical external variable influencing five perceived belief variables, namely perceived usefulness, perceived playfulness, perceived quality, perceived complexity and perceived cost. Regarding consumer satisfaction for free VOD service, it had no direct effect but indirect effect on the purchase behavior, meaning that the satisfaction causes purchase intention for VOD contents via the cognitive attitude. Also, the moderating e!ect of use experience on the relationship between the belief variables and the purchase intention was confirmed. Users with much experience showed a higher perception for usefulness and quality, whereas users with less experience placed a higher value on the hedonic factors and costs. In contrast to previous studies on IPTV that mainly focused on determinant of IPTV subscription, this paper analyzed VOD that is a killer application of IPTV in identification of key factors for the acceptance. The findings provide IPTV operators some strategies to create customer value and improve profitability.

Purpose - This study aims to develop and empirically test a multi-dimensional service convenience scale with the dimensions and measurement items of service convenience perceived by Korean consumers in retail contexts. Research design, data, and methodology - The study adopts the framework suggested by Berry et al. (2002) and conceptualizes service convenience as a second-order reflective construct comprising 31 items. Three department store chains (Hyundai, Lotte, and Shinsegae) and three discount store chains (E-mart, Homeplus, and Lotte Mart) were involved 510 valid responses were used for the empirical testing. Results - The measurement model is acceptable for internal consistency, convergent validity, and discriminant validity. Further, the structural model results show that service convenience is positively related to satisfaction. Results of the rival model comparison indicate that the proposed second-order factor model provides a better fit to the data than both the five-factor and the one-factor model. Conclusions - The multi-dimensional, second-order conceptualization of service convenience is robustly supported. This study provides psychometrically valid scales to measure service convenience in retail contexts as conceptualized by Berry et al. (2002).

All data were segregated according to the departmental frequencies and their contents. To come up with for environmental and patient satisfaction improvement, all complaints or issues were communicated with hospital administrators, medical and nursing staff and employees. Comprehensive customer satisfaction activities including improving phone etiquette were discussed in Customer Satisfaction Team, CQI Team and each Department. All opportunities for improvement were implemented. Feedback actions were discussed. Results : A total of 317 cases were collected. Issues regarding parking and other accommodation facilities were most common complaints that were 14.5% of total. Issues regarding admission rooms (10.7%), admission procedures (10.7%), waiting room environment (8.8%), nurses and nurse assistants (7.6%), physicians (6.6%) and others (23%) followed. Thirteen of 45 departments received more than 8 complaints. The Nursing Department had the most complaint, receiving 9.8% of total complaints. Complaints regarding the Nursing Department were predominantly related to the environment of patient rooms. The Department of Psychiatry for phone etiquette (4.7%), Department of Otolaryngology for the nursing staff's attitude and phone etiquette (4.4%), and the Admission Department followed. As a part of efforts to improve patient satisfaction, a new parking structure was built and reallocation of the parking space was done. Renovation of other accommodation facilities were carried out by hospital administration, Monthly phone call and answering attitude survey was done by QI Department. Based on this survey we made a phone etiquette manual and distributed throughout the hospital. Compare to the last year, Patient Satisfaction Index measured by Korea Productivity Center using National Customer Satisfaction Index was improved 7 points. According to our organization's own study, we confirmed the phone etiquette was improved 11% than last year. Conclusions : Issues related to parking and other accommodation facilities ranked first followed by complaints made regarding the patient care area, the admission and cashier process, and nurses' and doctors' attitude. The Nursing and Psychiatry Departments need improvement regarding phone etiquette. Results were shared and played a vital role in policymaking and strategic planning of the hospital. It is imperative that we keep our database updated by listening to and solving the needs of each patient.
