By 2025, South Korea is expected to enter an ultra-aged society with the elderly comprising 20.6% of the population. We measured changes in health status before and after by the use of a "Cognition-Emotion Enhancement Chatbot Integrated Product" among Baby Boomer generation women. Fifty participants, proficient in smart device usage and willing to provide data, were selected from health communities in Seoul. After excluding some applicants, 43 Baby Boomer women were analyzed. Results revealed significant differences in post-chatbot use physical activity (43.5.21 ± 1310.39 MET) and depression levels (6.84 ± 3.53). Correlation between the two variables was not statistically significant. The findings suggest specific effects of the chatbot on physical activity and depression, emphasizing the need for future research with diverse health indicators.

Today, governments are evolving into digital governments that actively leverage digital technologies to promote national development. Government websites play a crucial role as key elements in reshaping the interaction between individuals and the government. Within this context, government website chatbots play an important role in facilitating citizens' easy access to information. However, the chatbot ND on the National R&D Knowledge Information Portal (NTIS) exhibits low usage rates. This study proposes a framework based on user journey mapping to address the usability issues of chatbot ND. By delineating the user journey into pre-usage, in-usage, and post-usage stages, the study aims to identify points of inconvenience experienced by users at each stage and provide enhanced user experiences.

The advent of the era of data age and advances inartificial intelligence technology has led to innovations in various business areas. In particular, many attempts have been made to improve the stability of the marine accident, which has not previously been applied by a data-drive approach. Most of the marine accidents happen at a time when the vessel isapproaching a port and preparing for berthing. Although the cause of the accident has many factors, it is often caused by the difficulties of communication between the ship navigator and the control center. In particular, communication in English makes difficulties for navigators, not English astheir first language. To do this, proper English conversation education forsailors is very important. In order to support the issue, this study presents data and framework for the development of a chatbot for ship safety education.

Classroom response systems (CRS) have been proven to have positive educational effects on student engagement and participation by allowing immediate feedback to both students and instructors. We explore the use of a chatbot and slide widget-based CRS to overcome some of the challenges of existing mobile-based CRSs while retaining their advantages. Our system uses widely available instant messaging services and operates web-based slide widgets that can be seamlessly integrated into instructors' slides to visualize student feedback in various formats. The student survey results indicate that our system is as effective as conventional CRSs in promoting student engagement and participation.

신입생과 재학생들이 학사업무에서 문의사항이 있을 시 전화를 이용하는 방법보다 변화된 생활 환경에 맞게 SNS를 많이 이용하므로 이를 통한 문의가 증가하고 있어 이를 자동으로 응답할 수 있도록 챗봇(Chatbot)을 활용하는 사례도 증가하고 있다. 이에 경운대학교 학사업무에 대한 문의를 자동으로 응답하는 챗봇을 개발하여 학생들에게 제공하여 효율적인 응답체계를 만들고자 한다. 이를 위해 Dialogflow플랫폼을 사용하여 챗봇에게 질문했을 때 답을 하는 응답내용을 개발하고, Webhook을 사용해서 Facebook Messenger플랫폼에 연동하여 챗봇을 Facebook Page에 만들어 응용하였다. 또한 실제 채팅을 통해 실험하여 결과를 확인하였다.

증가하는 메시징 앱 이용자 수, 언제 어디서나 시간과 장소에 제한받지 않는 고객 응대 서비스 그리고 대화형이라는 친근성 등은 챗봇(Chatbot)의 대표적인 장점들이다. 과거에는 단순히 패턴을 찾아 이미 설정된 기계적인 반응만을 했지만, 최근에는 여러 기술, 특히 AI 기술의 발달로 실생활에서도 도움을 줄 수 있는 챗봇들이 많아지기 시작했다. 본 논문에서는 인터넷이나 핸드폰 앱으로 영화 예매하는 것이 익숙하지 않은 사람이나 채팅을 하는 것이 익숙한 사람들이 신속, 편리하게 영화 예매를 할 수 있도록 지원하는 챗봇을 구현하고자 한다. 이를 위해 Dialogflow를 사용해서 예매자가 영화의 필수 정보들을 자연스러운 채팅을 통해 파악하도록 한다. 또한 영화와 관련된 키워드만 언급해도 되묻기 기능을 추가해 해당 영화를 유추할 수 있는 질의를 통해 정확한 예매를 지원한다.

We aim to investigate the effects of task type and user gender on the expected gender of chatbots. We conducted an online study of 381 participants who selected the gender (female, male, or neutral) for chabots performing six different tasks. Our results indicate that users expect human- gendered chatbots for all tasks and that the expected gender of a chatbot is significantly different depending on the task type. Users expected chatting, counseling, healthcare and clerical work to be done by female chatbots; professional and customer service work were expected to be done by male chatbots. A tendency for participants to prefer chatbots of the same-gendered as themselves is revealed in several tasks for both male and female users. However, this homophily tendency is stronger for female users. We conclude by suggesting practical guidelines for designing chatbot services that reflect user expectations.

In software engineering, requirement analysis is an important task throughout the process and takes up a high proportion. However, factors that fail to analyze requirements include communication failure, different understanding of the meaning of requirements, and failure to perform requirements normally. To solve this problem, we derived actors and behaviors using morpheme analysis and BERT algorithms in the Korean requirement document and constructed them as ontologies. A chatbot system with ontology data is constructed to derive a final system event list through Q&A with users. The chatbot system generates the derived system event list as a requirement diagram and a requirement specification and provides it to the user. Through the above system, diagrams and specifications with a level of coverage complied with Korean requirement documents were created.

Since the first outbreak of COVID-19 in 2019, it has caused a huge blow to the restaurant industry. However, as social distancing was lifted as of April 2022, the restaurant industry gradually recovered, and as a result, interest in restaurant start-ups increased. Therefore, in this paper, big data analysis was conducted by selecting "restaurant start-up" as a key keyword through social media big data analysis using Textom and then conducting word frequency and CONCOR analysis. The collection period of keywords was selected from May 1, 2022 to May 23, 2023, after the lifting of social distancing due to COVID-19, and based on the analysis, the development of a restaurant start-up consulting chatbot service is proposed.

Chatbots have become very popular in our times and are used in several fields. The emergence of chatbots has created a new way of communicating between human and computer interaction. A Chatbot also called a "Chatter Robot," or conversational agent CA is a software application that mimics human conversations in its natural format, which contains textual material and oral communication with artificial intelligence AI techniques. Generally, there are two types of chatbots rule-based and smart machine-based. Over the years, several chatbots designed in many languages for serving various fields such as medicine, entertainment, and education. Unfortunately, in the Arabic chatbots area, little work has been done. In this paper, we developed a beneficial tool (chatBot) in the Arabic language which contributes to educating people about the Prophet's biography providing them with useful information by using Natural Language Processing.
