In recent years, several studies have proposed making use of the Twitter micro-blogging service to track various trends in online media and discussion. In this study, we specifically examine the use of Twitter to track discussions of food safety in the Korean language. Given the irregularity of keyword use in most tweets, we focus on optimistic machine-learning and feature set selection to classify collected tweets. We build the classifier model using Naive Bayes & Naive Bayes Multinomial, Support Vector Machine, and Decision Tree Algorithms, all of which show good performance. To select an optimum feature set, we construct a basic feature set as a standard for performance comparison, so that further test feature sets can be evaluated. Experiments show that precision and F-measure performance are best when using a Naive Bayes Multinomial classifier model with a test feature set defined by extracting Substantive, Predicate, Modifier, and Interjection parts of speech.

Purpose: The purpose of the study is to identify the influence of the hospital mobile app service quality on consumer satisfaction, involvement, and re-use intention of consumers who have experience in hospital mobile app service. Methodology: The survey was conducted on 230 users. The collected data were analyzed using correlation analysis, multiple regression analysis, and the Process Model in Hayes(2013). Findings: (1)The usability, reliability, and medical information provision among the service quality factors of hospital mobile apps had an effect on reuse intention, and consumer satisfaction partially mediated. (2)The usability and the provision of medical information were partially mediated by the involvement, which also affected the intention to reuse. (3)Only reliability showed an age-moderated effect. In reliability and re-use intent, age was a moderated mediating effect that controlled the effect of consumer satisfaction. Practical Implications: The results of this study provide initial data of mobile app services centered on hospitals and prove the type of consumer usage. It suggests that it can be used to attract potential consumers of hospitals and strategies to increase the use of mobile apps.

In this study, we explored the potential of integrating interactive AI callbot technology into the medical consultation domain as part of a broader service development initiative. Aimed at enhancing patient satisfaction, the AI callbot was designed to efficiently address queries from hospitals' primary users, especially the elderly and those using phone services. By incorporating an AI-driven callbot into the hospital's customer service center, routine tasks such as appointment modifications and cancellations were efficiently managed by the AI Callbot Agent. On the other hand, tasks requiring more detailed attention or specialization were addressed by Human Agents, ensuring a balanced and collaborative approach. The deep learning model for voice recognition for this study was based on the Transformer model and fine-tuned to fit the medical field using a pre-trained model. Existing recording files were converted into learning data to perform SSL(self-supervised learning) Model was implemented. The ANN (Artificial neural network) neural network model was used to analyze voice signals and interpret them as text, and after actual application, the intent was enriched through reinforcement learning to continuously improve accuracy. In the case of TTS(Text To Speech), the Transformer model was applied to Text Analysis, Acoustic model, and Vocoder, and Google's Natural Language API was applied to recognize intent. As the research progresses, there are challenges to solve, such as interconnection issues between various EMR providers, problems with doctor's time slots, problems with two or more hospital appointments, and problems with patient use. However, there are specialized problems that are easy to make reservations. Implementation of the callbot service in hospitals appears to be applicable immediately.

Changing social conditions have resulted in a situation where elderly patients are no longer cared for by family and where medical care hospitals play a more prominent role. In this study, the unique elements of the medical service required from a long term care hospital were identified using conventional and exploratory analysis, and the causal relationship between medical service quality, relationship quality, and Revist intent was confirmed. The intermediary role and the quantitative importance of relationship quality (including trust and commitment) were also characterized. This study identifies the key points and indicators that the administrators of a long term care hospital can use to effectively plan their medical service offering in order to secure the commitment of customers through relationship quality. The theoretical indications of this study are set out below. First, four factors are selected as being the key elements determining service quality: medics, administrative service, healthcare environment, and subsidiary facilities. Second, it seems that medics, administration service, and the healthcare environment have some effect on the evaluations made in relation to trust and satisfaction (subsidiary facilities are not considered to be a key element). Third, patient satisfaction has a positive impact on trust and commitment and can be regarded as a key element for establishing connections. Fourth, commitment is likely to be strengthened when trust is significant. Fifth, as trust and commitment increase, revist intent strengthens. Lastly, this study illustrates how the levels of trust and commitment play a modulating role between patient satisfaction and revist intention. There are many practical indications from the findings of this study. First, the influences of medics, the administrative service, and the healthcare environment on trust and satisfaction vary. Especially, the healthcare environment is likely to be more important than medics. Accordingly, it is essential to establish an elderly-friendly environment, to improve a hospital's structure, and to maintain a clean environment. Second, medics must show compassion to their patients and be patient when providing explanations to elderly patients who often lack powers of concentration. Third, in order to establish patient trust, it is essential that medics provide an excellent medical service. Ultimately, these elements of relationship quality may strengthen the revist intention of elderly patients.

본 연구는 고령자의 삶의 만족도를 높이기 위해 가상현실(Virtual Reality: VR) 기기 및 콘텐츠를 활용하고 체험하는 것에 초점을 두었다. 여가 활동은 일자리가 없는 고령자의 주된 활동이다. 결과적으로, 여가 활동의 다양성과 질이 고령자의 삶의 만족도에 영향을 미친다. 동영상 콘텐츠를 포함한 가상현실 서비스는 고령자들에게 발전되고 흥미로운 경험들을 제공할 수 있다. 전세계에 걸쳐, 인구 고령화는 각 사회에서 가장 중요한 문제들 중 하나가 되었다. 고령화에 따른 사회적, 경제적 부담은 한국을 포함해 세계의 지속가능성에 심각한 도전이 되고 있다. 저자들은 고령 피험자(50세부터 90세까지)를 대상으로 VR의 사용을 연구한다. 본 실험에서 저자들은 시스템 품질, 인터페이스 품질, 현존감, 즐거움, 재이용 의도, 첨단과학기술 인식을 포함한 요인들을 연구하고 측정한다. 회귀분석에서 근접감(t=5.381, p<.01)과 선명감(t=4.494, p<.01)은 VR의 현존감에 유의미한 영향을 미치는 요인이다. VR의 현존감(설명 변수)은 즐거움(t-4.312, p<.01)과 재이용 의도(t=3.323, p<.01)에 유의미한 영향을 미친다. 그러므로 고령 피험자는 VR에서 현존감을 더 느낄수록, 더욱 높은 즐거움과 재이용 의도를 느낀다고 볼 수 있다. 결국, 새로운 과학기술에 익숙하지 않은 고령자도 가상현실 서비스를 이용해 여가 활동의 질을 개선할 수 있음을 시사한다.

Purpose The purpose of this study is to investigate the intention of early application users in consideration of the characteristics of digital finance-based MyData service users. It is expected that user characteristics will affect the intention to use MyData service, which has not yet been advanced, and accordingly, it will examine how the characteristics of the initial users of MyData service and the intention to use it are connected. Design/methodology/approach The model used in this study is a value-based adoption model (VAM), and a lot of research has been conducted on information technology and online user acceptance and continuous use intention of online users. VAM has been proven useful through empirical analysis in many studies. The value-based acceptance model is a method of analyzing the intention to use Benefits and Sacrifices as the main elements of perceived value. It can be said to be a model that can analyze the benefits of use and the sacrifices to be made. Findings According to the analysis results of this study, it was found that usefulness, enjoyment, and reliability, which are the benefits of MyData service apps, had a positive effect on perceived value, which is partially consistent with existing research results. However, it was found that complexity, which is the sacrifice of MyData service apps, negatively affects perceived value and security has no negative impact. The results of security are considered to be complementary to financial institutions because MyData service deals with financial data based on personal information, and the research hypothesis is rejected because users' demands are relatively low. Therefore, MyData service apps should do more to increase benefits (usefulness, enjoyment, and reliability) than to reduce sacrifice (complexity) to users.

Purpose - Based on preceding studies, this thesis focuses on the finding of the definition and category of mobile tourism application and deriving out its characteristics. And after looking for how they make influences on continuous intention to use, we make empirical study with TAM model. Research design, data, and methodology - There are many Chinese tourist who visit Korea with user's constant intention to use of tourism application. This study is to find out the definition and category of mobile tourism application through research of preceding study and to fomulate the research model and hypothesis that how tourism application attributes (convenience, interaction, accessibility, local basis, security) affect constant intention to use of mobile tourism application. In order to verify a hypothesis, we conducted a survey for Chinese users of tourism application. In empirical study, we analyzed a structure model for frequency analysis, reliability analysis, exploratory factor analysis, validity analysis through IBM SPSS Statistics 21.0 and IBM SPSS AMOS 21.0 Results - Among tourism applications, convenience, interaction, accessibility and local basis have positive effects on both perceived usefulness and perceived easiness respectively. But security does not. Also perceived easiness has a positive effect on perceived usefulness. Finally, perceived usefulness and perceived easiness have positive effect on constant intent to use. Conclusions - Tourism application enterprises should put emphasis on design such as menu or function in order to simplify the operation of new services for new customers. Therefore, comfortable user interface and development of useful function can improve tourism application. Consequently, it leads to the promotion of tourism application. Also, when users perceive tourism application as a useful media which is easy, comfortable and useful content, the degree of constant intention to use becomes increased. It is important to provide plentiful and useful contents for customers and to develop user interface such as easy operation because these factors have positive effects on constant demand and use of tourism application.
