This paper proposes a method of integrating ChatGPT with traditional chatbot systems to enhance conversational artificial intelligence(AI) and create more efficient conversational systems. Traditional chatbot systems are primarily based on classification models and are limited to intent classification and simple response generation. In contrast, ChatGPT is a state-of-the-art AI technology for natural language generation, which can generate more natural and fluent conversations. In this paper, we analyze the business service areas that can be integrated with ChatGPT and traditional chatbots, and present methods for conducting conversational scenarios through case studies of service types. Additionally, we suggest ways to integrate ChatGPT with traditional chatbot systems for intent recognition, conversation flow control, and response generation. We provide a practical implementation example of how to integrate ChatGPT with traditional chatbots, making it easier to understand and build integration methods and actively utilize ChatGPT with existing chatbots.

Purpose: The aim of this study was to identify Russian inpatients' expectation and satisfaction with nursing service, and further, to analyze the relationship between these variables. Methods: A structured questionnaire was used to survey for 81 Russian inpatients. The survey was conducted from January to June, 2014. Results: Empathy and assurance significantly influenced nursing service expectation and satisfaction. Nursing service expectation was statistically significant for the number of visit to Korea, and nursing service satisfaction was statistically significant for gender, monthly income and primary care giver during hospitalization. Revisit intention was significantly different according to religion, medical department and primary care giver during hospitalization. There were positive correlations between nursing service expectation and satisfaction, and between nursing service satisfaction and intention to revisit the hospital. Conclusion: The results of this study show that the level satisfaction with nursing service influences Russian inpatients' intention continue using the hospital. Therefore, in order to increase the intention to revisit the hospital Korea hospital employees, especially nurses, need to develop nursing service strategies according to general characteristics, culture and nationality of foreign patients.

Objectives : To examine the factors associated with the use of the prenatal care services provided by the Ministry of Gender Equality and Family by married migrant women in Korea. Methods : We employed data from the 2015 Nationwide Multiculturale Family Survey. We selected 19- to 39-year-old married immigrant women with children aged 5 years or less for the study (N=1,579). We included four predisposing factors, six enabling factors, and two need factors based on the Andersen's Health-care Utilization Model. Results : Only one third of married immigrant women(31.6%) used prenatal care service and 45.9% of them reported prenatal care service needs. Area of residence, country of birth, and Korean language proficiency were significantly associated with prenatal care service use. Further, age, country of birth, length of time in Korea, household income, and discrimination experience were significantly associated. Conclusions : Findings suggest the need to develop strategies to improve accessibility to prenatal care service use especially for married immigrant women from developing countries, low-income families, having poor Korean language proficiency or having discrimination experience.

Previous QoS-aware service composition methods mainly focus on how to generate composite service with the optimal QoS efficiently for a single request. However, in the real application scenarios, there are multiple service requests and multiple service providers. It is more important to compose services with suboptimal QoS and maintain the load balance between services. To solve this problem, in this paper, we propose a service composition method, named as dynamically change and balancing composition method (DCBC). It assumes that the QoS of service is not static, and the services can adjust the value of QoS to gain more opportunities to be selected for composition. The method mainly includes two steps, which are the preprocessing step and the service selection step. In the preprocessing step, a backward global best QoS calculation is performed which regarding the static and dynamic QoS respectively; then guided by the global QoS, the feasible services can be selected efficiently in the service selection step. The experiments show that the DCBC method can not only improve the overall quality of composite services but also guarantee the fulfill ratio of requests and the load balance of services.
