최근 국내 초고속 인터넷 서비스가 대부분의 가정에서 이용하는 보편적인 서비스로 자리를 잡게 됨에 따라 사업자들 간의 가입자 유치 경쟁도 점점 더 치열해지고 있다. 사업자들 간의 출혈경쟁을 줄이고 수익성을 높이기 위해서는 기존 고객의 충성도를 높이는 방어적인 마케팅 전략이 효과적이다. 따라서 본 연구에서는 설문 조사를 통해 초고속 인터넷 서비스의 충성도에 영향을 미치는 요인들을 도출하였다. 분석결과, 서비스 자체의 품질 및 애프터 서비스에 대한 만족 정도가 서비스의 충성도에 긍정적인 영향을 미치는 것으로 나타났다. 이러한 결과는 실무자들에게 고객 전략에 대한 시사점을 제공할 것으로 기대한다.

As a trend of modern service industry, self-service has been widely concerned by all walks of life, but there is a lack of literature on systematic management of the overall research in this field. Recently, people's lifestyle has been forced to change due to the influence of COVID-19, while there have been some changes in the field of self-service research. Based on the Web of Science data source, this study takes the literature of self-service field before and after the outbreak of COVID-19 as the research object, and summarizes the development process, research status and future research trend of self-service field through the Citespace visualization tool. The research shows that firstly, academic circles continue to be enthusiastic about self-service field research, cooperation between countries is becoming more and more diversified. Secondly, the communication between researchers is becoming more and more intensive, and the cooperation between different disciplines gradually becomes the mainstream. Third, related research gradually shifted to the practical application of technology, the research perspective gradually shifted from the initial traditional retail perspective industries such as tourism services. Finally, the role of customer experience and participation behavior in self-service process is gradually emphasized.

The mobile communication technology would be one of the most appropriate means for achieving process innovation in the actual business area. This article performs a simulation study to examine the effect of introducing a mobile technology to the after-sales service and its logistics process. The performances of the two different systems, before and after introducing a mobile technology, are examined based on operational cost, operational efficiency, and customer service level using a discrete event simulation. The real-world data, extracted from a leading Korean electronics firm, was collected for this study. The results show that the TO-BE(after) model outperforms the AS-IS(before) model over all the performance indices. And the effects of introducing the mobile technology are more significant on the more tightly controlled inventory policy.

This study is to ascertain pre-service teachers' conceptions for the causes of season change, to verify their conceptional mistakes, and to analyze how their conceptions are changed while presenting Disproof-Experiment Model where they cannot explain it with their current conceptions. 32 junior students of Education universities, pre-service elementary teachers, located at the middle of Korea participated in this research including two interviews and one experiment activity. As a result of analyzing of the data, the pre-service teachers held diverse conceptions for the causes of season change such as to mistake the phenomena, the distance between the earth and the sun, the tilting of the rotation axis and the revolving around the sun while changing the tilting direction of the rotation axis as the cause. After applying Disproof-Experiment Model designed by the researchers in order to change the current conception above, the conception changes of the pre-service teachers were investigated. Diverse Disproof-Experiment Models were used differently depending on the pre-service teachers' conceptions. As a result of the application of Disproof-Experiment Model, 26 out of 28 pre-service teachers were changed to scientific conceptions. It was determined that in order to modify pre-service teachers' conceptions, designing and presenting the Disproof-Experiment Model appropriate to their conceptions are effective after analyzing their conceptions. In case of conceptions that pre-service teachers feel difficult, it was established that unraveling experiment models prescribed after investigating the preconceptions and identifying the misconceptions are important.

Purpose: We investigated the association between defoliant exposure and survival to discharge after out-of-hospital cardiac arrest. Methods: This is a retrospective case-control study based on the cardiopulmonary resuscitation (CPR) registry. The electronic medical records of out-of-hospital cardiac arrest victims from 6/9/2008 to 12/31/2016 were analyzed statistically. The case patients group had a history of defoliant exposure while the control group did not. Among the 401 victims studied, a total of 110 patients were male out-of-hospital cardiac arrest patients. Baseline characteristics and the parameters involved in cardiac arrest were analyzed and compared between the two groups after propensity score matching. The primary outcome was survival to discharge, and secondary outcomes were sustained return of spontaneous circulation (ROSC) and survival to admission. Results: After propensity score matching a total of 50 patients (case=25, control=25) were analyzed. Primary outcome (survival to discharge) was not significantly different between case and control groups [(OR, 1.759; 95% C.I., 0.491-6.309) and (OR, 1.842; 95% C.I., 0.515-6.593), respectively]. In the subgroup analysis, there were also no significant differences between the control group and subgroups in primary and secondary outcomes according to defoliant exposure severity. Conclusion: There is no statistically significant association between defoliant exposure and survival of out-of-hospital cardiac arrest.

The present study was undertaken to clarify the changes in blood chemical values of indigenous Korean striped calves according to age. Blood samples were collected from 15 calves (8 females and 7 males) reared at the Gyeongsangbukdo Livestock Research Institute and the levels of various chemicals in serum were analyzed. The mean total protein, albumin and globulin concentration in calves increased from 2 weeks after birth, and the levels in females were higher than those in males at 8 weeks after birth. The mean glucose concentration increased significantly at 2 weeks after birth. The mean blood urea nitrogen concentration increased from 2 weeks after birth, whereas the mean creatinine concentration decreased significantly from 2 weeks after birth. The mean uric acid concentration increased gradually from 2 weeks after birth. The mean glutamic oxaloacetic transaminase and glutamic pyruvic transaminase concentration increased significantly from 2 weeks after birth. The mean total bilirubin concentration tended to decrease from 2 weeks after birth. The mean triglyceride, total cholesterol and high density lipoprotein cholesterol concentration increased significantly from 2 weeks after birth. In conclusion, the data obtained from this study may be valuable as a standard for interpreting results of biochemical analyses in indigenous Korean striped calves.

본 연구는 방송 통신 산업에서 기업의 서비스 회복 활동이 고객의 상품 전환율에 미치는 영향을 연구 하는 것이다. 한국의 방송통신시장은 이미 포화상태에 이르렀으며, 서비스 수준이 메이저 회사에 비해 상대적으로 낮은 중소기업들의 고객이동은 점점 증가하는 추세이다. 그리고 일단 한번 이동한 고객은 돌아오지 않는다. 이에 따라, 서비스 기업에게 고객유지는 점점 더 중요해지고 있기 때문에 CRM이 강화되는 추세다. 그러나 대규모 투자와 지속적인 비용이 필요한 CRM은 중소기업에서 운영하기 쉽지 않다. 본 연구에서는 CRM환경이 열악한 기업이 고객의 서비스 실패 상황을 작지만 즉각적인 회복활동이 상품전환에 어떠한 영향을 미치는지를 실 기업데이터를 사례를 통해 검증하고자 하였다. 본 연구에서는, 서비스 실패를 경험한 고객의 이동률이 약 2~5배 (월 평균 전체고객 대상 상품전환율 1.3%)가 높았으며, 적극적인 회복 활동은 상품전환율 감소에 영향을 미친다는 결과를 도출 하였다. 본 연구의 시사점은 고객의 상품전환(Churn) 의사에 따른 서비스 회복활동 보다는 서비스 실패 확인 시 기업의 서비스 회복활동 노력이 상품전환율을 낮추어, 기업의 다양한 서비스 실패 환경에서의 서비스 회복 노력의 중요성을 재차 확인할 수 있었으며, 상품전환(Churn) 의사확인 후 방어활동 비용 대비 상대적으로 저 비용으로 효과를 얻을 수 있다는 결론을 도출 할 수 있었다.
