The purpose of this study is to evaluate the service attributes and consumer reactions of telemedicine apps in South Korea and visualize their differentiation by constructing positioning maps. We crawled 23,219 user reviews of 6 major telemedicine apps in Korea from the Google Play store. Topics were derived by BERTopic modeling, and sentiment scores for each topic were calculated through KoBERT sentiment analysis. As a result, five service characteristics in the application attribute category and three in the medical service category were derived. Based on this, a two-dimensional positioning map was constructed through principal component analysis. This study proposes an objective service evaluation method based on text mining, which has implications. In sum, this study combines empirical statistical methods and text mining techniques based on user review texts of telemedicine apps. It presents a system of service attribute elicitation, sentiment analysis, and product positioning. This can serve as an effective way to objectively diagnose the service quality and consumer responses of telemedicine applications.

This paper is a study to check the flow of how addiction to media services has been studied from a long-term perspective, and to identify variables that can be the basis for future addiction research. Researchers noted the addiction of media services in adolescents in particular, and identified a combination of factors depending on the background of the times. Addiction variables were largely aggregated into four properties: adolescent properties, personal properties, media properties, and media-dependent properties. Addiction variables belonging to the attribute were influenced by major media and divided into four periods. During the study period, the frequency of variables was most related to personal attributes, followed by media attributes, adolescent attributes, and media-dependent attributes. Also Individual attribute variables gradually shifted from object-relationship to individual psychological factors. Variants in media attributes were influenced by the introduction and spread of new media. Variations in adolescent and media-dependent attributes have been weak in studies that observe teenagers' motivations for media use or are related to addiction, and no papers have been published since 2020. Although addiction research on media services is important in terms of industry, there has been an emphasis on social aspects, based on the results of this study, we hope to continue to study the variables of service users who can be used in terms of industry.

This study investigated consumer convergence preferences for healthcare information service in social media using the multi-attribute utility theory. The multi-attribute utility theory is an approach for compositional modeling attributes wherein researchers compute the overall service utility by aggregating the evaluation results for attribute values. We found that healthcare information service consumers in social media evaluate the service preference through the multi attributes - Update, Cost, Usefulness, Usability, Reliability. And the study shows that individual preference by estimating weight of each attribute in the services influences the service use intention. So we believe that estimating preferences with multi-attribute utility theory will predict business success of the services in a new media, and for a successful business of the social media services marketers should assess the consumer's preference using the multi-attributes.

The objective of this paper is to quantify economic values of parcel service attributes (safety, reliability, quickness, and kindness and customer service) using the contingent choice method and to investigate impact factors (such as sex, age, and education), which influence choice of desirable parcel services. As empirical results, the marginal willingness-to-pay for multiple attributes of parcel service is calculated as about 2,349.6 KRW for the safety attribute, about 829.3 KRW for the reliability attribute, about 588.5 KRW for the quickness attribute, and about 358.8 KRW for the kindness and customer service attribute, according to the estimation model without covariates. The overall results indicate that the safety attribute ranks highest among parcel service attributes, followed by the reliability attribute, quickness attribute, and kindness and customer service attribute. These results can be useful in the decision-making process for establishing desirable pricing policies for parcel service.

In order to suggest ways to enhance service competitiveness in cruise and destination, this study developed a measure of cruise tour service and analyzed the impact and relative importance on customer satisfaction. Specifically, for the service quality analysis, based on the SERVPERF model, the specialty of the industry was reflected through the arguments of tourism and transport logistics, and the three factors of cruise service quality and destination service quality were derived and utilized as measurement tools. As an analysis method, factor and reliability analysis were conducted using data collected via a survey. Next, correlation analysis was conducted to analyze the relationship between variables and regression analysis was performed to check the impact of cruise tour service quality on customer satisfaction. The study found that both cruise service attributes and destination service attributes had a positive effect on customer satisfaction and that the relative importance of service attributes was identified. Accordingly, it was found that the service quality should be formed by reflecting arguments in the tourism and transport logistics sectors and that the service should be further improved and developed according to the importance of the service attributes so as to enhance cruise tour products.

인터넷을 기반으로 시스템의 규모가 점차 커짐에 따라 연합된 시스템으로 변화되고 있으며, 더 나아가서는 이러한 분산 시스템들이 모여 보다 광범위한 광역 분산처리 환경을 조성하고 있다. 이러한 환경을 이루어 수많은 객체들은 이름이나 속성에 의해 다양한 중복된 성질을 갖는다. 일반적인 객체들을 찾는 방법으로 객체의 이름에 따른 서비스가 대부분이다. 그러나 점차 객체가 갖는 서비스 내용(속성)을 이용하여 객체를 검색하는 메커니즘의 필요성이 높아지고 있다. 광역 분산처리 환경에서는 객체가 갖는 이름과 속성에 따라 네이밍과 트레이딩 기능을 모두 사용하여 사용자에게 투명한 서비스를 제공해야 한다. 따라서 본 논문에서는 광역 분산 환경에서 네이밍과 트레이딩 서비스의 기능을 혼합한 바인딩 서비스 모델을 제시한다. 이는 이름과 속성기반의 단일 객체뿐만 아니라 중복객체의 효과적인 탐색과 바인딩시 부하분배를 꾀하여 네트워크 상의 부하 균형화를 유지하도록 한다. 이를 위해, 먼저 분산 객체에 대한 모델을 제시하고, 이들을 바인eld 처리 방안 그리고 연합을 위한 모델을 보인다.

This study aims to give insight into better understanding how service quality influences customers' attitude and behavior in terms of loyalty as well as how its effects vary by the types of restaurants (family restaurants or fast food restaurants). The results of the study are summarized as follows. First, perceived service quality, which consists of food, service, menu and atmosphere, made a significant impact on customer satisfaction for food, menu, atmosphere, and service, respectively. Second, the study examined how perceived service quality affected future expectations, and found only food turned out to be a significant factor. Third, customer satisfaction affected future satisfaction and customer loyalty, and it had a greater impact on attitudinal loyalty than behavioral loyalty. Fourth, future satisfaction affects customer loyalty, and it had a greater impact on attitudinal loyalty than behavioral loyalty. Fifth, the study examined how service quality, customer satisfaction and future expectation affected attitudinal loyalty and behavioral loyalty differently by different types of the food service industry (family restaurants or fast food restaurants) and found out there were some differences in the effects of customer satisfaction on behavioral loyalty and the future expectations and attitudinal loyalty on behavioral loyalty. The marketing implication is that service providers should be one step ahead in understanding the service quality perceived by customers (food, service, menu, and atmosphere). In addition, they should understand that establishing long-tenn relationships with customers by providing high quality service bas a direct impact on their business performance. Furthermore, management in family restaurants and fast food restaurants should include the improvement of service quality in their employee training programs.
