In the era of the 4th industrial revolution, the demand for convergence between ICT technologies is increasing in various fields. Accordingly, a new term that combines data, network, and artificial intelligence technology, DNA (Data, Network, AI) is in use. and has recently become a hot topic. DNA has various potential technology to be able to develop intelligent application in the real world. Therefore, this paper introduces the reviewed papers on the service image placement mechanism based on the logical fog network, the mobility support scheme based on machine learning for Industrial wireless sensor network, the prediction of the following BCI performance by means of spectral EEG characteristics, the warning classification method based on artificial neural network using topics of source code and natural language processing model for data visualization interaction with chatbot, related on DNA technology.

As population aging progresses, there is a growing demand for IT technology that can relieve the psychological anxiety of the elderly living alone, recognize the dangerous situation, and check the family members' affection. In this paper, we describe the development of a speech recognition speaker that enable senior users to give simple interactive commands by voice and monitor the status of the user. The speaker analyzes the user's voice, grasps the conversation contents through the chatbot, connects the desired service to the user, and provides the result again by voice. By using this speaker, senior users can feel relaxed by natural conversation, and can monitor the status of danger more easily.

In this paper, we propose an ordering chatbot that can process multiple keywords based on recursive slot-filling method. In general, in case of an order service using chatbots, the whole order process is performed only according to the sequence defined by the developer. That is, among all the information needed for the whole order process, only one input can be processed at one time. In order to reduce processing step for the order, we propose a recursive slot-filling method which fills out multiple slots per one time by extracting multiple keywords. First, a keyword array for the order is created according to the order related information. Next, from the input sentence of a user, multiple keywords is extracted. Corresponding slots for a keyword array will be filled with the extracted keywords. Finally, recursive routine will be executed to fill out all the blank in the keyword array. The usability and validity of the proposed method will be shown from the implementation of a smartphone application.

This study investigates the perception and adoption of ChatGPT (a large language model (LLM)-based chatbot created by OpenAI) among Korean users and assesses its potential as the next disruptive innovation. Drawing on previous literature, the study proposes perceived intelligence and perceived anthropomorphism as key differentiating factors of ChatGPT from earlier AI-based chatbots. Four individual motives (i.e., perceived usefulness, ease of use, enjoyment, and trust) and two societal motives (social influence and AI anxiety) were identified as antecedents of ChatGPT acceptance. A survey was conducted within two Korean online communities related to artificial intelligence, the findings of which confirm that ChatGPT is being used for both utilitarian and hedonic purposes, and that perceived usefulness and enjoyment positively impact the behavioral intention to adopt the chatbot. However, unlike prior expectations, perceived ease-of-use was not shown to exert significant influence on behavioral intention. Moreover, trust was not found to be a significant influencer to behavioral intention, and while social influence played a substantial role in adoption intention and perceived usefulness, AI anxiety did not show a significant effect. The study confirmed that perceived intelligence and perceived anthropomorphism are constructs that influence the individual factors that influence behavioral intention to adopt and highlights the need for future research to deconstruct and explore the factors that make ChatGPT "enjoyable" and "easy to use" and to better understand its potential as a disruptive technology. Service developers and LLM providers are advised to design user-centric applications, focus on user-friendliness, acknowledge that building trust takes time, and recognize the role of social influence in adoption.

This study examined whether there was a difference in the attitude toward the recommended product and the effect on the choice deferral according to information sources. Experiment 1 examined the relationship between trust in information and product attitude, and between uncertainty and choice deferral according to information sources (AI chatbot vs. human). Experiment 2 examined the impact of social presence, perceived personalization, and choice deferral according to whether anthropomorphism of AI chatbots or not. The research results are as follows. First, consumers were found to have a more positive attitude toward products recommended by AI chatbots (vs. human). Second, consumers were more choice deferral whether to purchase products recommended by AI chatbots (vs. human). Third, it was found that consumers' selection of products recommended by anthropomorphic AI chatbots (vs. impersonated AI chatbots) increased. Also, the implications of this study and future research directions were discussed.

기록 관리는 기록을 선별하고 수집하여 보존하는 것에서 이를 이용하는 방향으로 발전하고 있지만 여전히 기록관의 존재를 인지하지 못하는 잠재적 이용자가 많다. 따라서 본 연구는 기록관과 이용자의 상호작용을 지원하는 기록정보서비스 챗봇을 개발하였으며, 구체적인 개발 절차와 방법을 살펴보고자 하였다. 이에 본 연구는 적용 대상으로 명지대학교 대학사료실을 선정하고 이용자 요구 및 질의 분석을 진행하였고 챗봇 개발을 위한 논리적 구조 설계를 제안하였다. 이어 IBM Watson Conversation과 카카오톡 메신저를 통해 챗봇을 구축한 뒤, 시험 실행(Pilot run) 과정을 통해 기록정보서비스 챗봇이 이용자와 상호작용하는 모습을 확인할 수 있었다. 또한 기록정보서비스 챗봇 개발 과정의 경험을 바탕으로 시사점을 제시했다.

최근 비대면 원격강의의 비율이 증가하였지만 비대면 상황에서 원격으로 진행하는 강의로 인해 강의를 수강하는 학생들의 강의를 진행하는 교수와의 질문에 대한 즉각적인 상호작용과 피드백이 부족하고 교수 또한 비대면 상황에서 학생들과의 소통의 어려움으로 인해 질문에 대한 답변을 하는 것에 어려움 있다. 본 논문에서는 이러한 문제를 해결하기 위해 학생들에게 질문에 대한 즉각적인 답변을 해주고 교수에게는 질문-답변을 관리할 수 있는 인공지능 챗봇 웹 서비스를 제안한다. 웹 서비스는 강의를 수강하는 학생과 강의를 진행하는 교수로 나눠져 제공된다. 구현을 위해 Seq2Seq 모델을 활용하였고 질문-답변 데이터셋으로 학습을 하여 테스트 하였다.
