ABSTRACT
Automated information retrieval and servicing systems are a priority demand system in today's businesses to ensure instantaneous customer satisfaction. The chatbot system is an incredible technological application that enables communication channels to automatically respond to end-users in real-time and 24 hours a day. By providing effective services for retrieving information and electronic documents continuously and automating the information service system, the coronavirus disease (COVID-19) is challenging to promote graduate school programs, update news, and retrieve student information in this era. This article discusses automated information retrieval and services based on the architecture, components, technology, and experiment of chatbots. The chatbot system's primary functions are to deliver the course and contact information, answer frequency questions, and provide a link menu to apply for our online course platform. We manage the entire functional process of gathering course information and submitting an application for a course online. The final results compare end users' perceptions of chatbot system usage to onsite services to ensure that the chatbot system can be integrated into the university's information system, supporting university-related questions and answers. We may expand our chatbot system's connection to the university's server to provide information services to students in various informative areas for future research. © 2022 Institute of Advanced Engineering and Science.

ABSTRACT
Due to the global pandemic of Coronavirus 2019 disease (COVID-19), which began in late 2019, the world has changed and forced all human life to adapt by living in new forms, isolated from the community for both works and learning from their residences. COVID-19 disease undoubtedly has had an impact on the transportation ecosystem. Food, groceries, and even medications are delivered directly from restaurants to customers by deliverers, who can cause exposure and easily infect. Delivery solutions have been proposed and solved through the application of Internet of Things (IoT) knowledge to reduce customer-deliverer exposure. The Internet of Things concept can assist us in developing a mobility object or simulated car that operates without human intervention. The vehicle is programmed to run parallel to the surface of a continuous line, which is referred to as line following. Calibration of the line follower sensor is required to achieve a higher effective tracking accuracy under various conditions, such as line width or rough surface. This research examines and compares how the simulated car behaves when run on various linewidths in preparation for future application and development. © 2022 ACM.
ABSTRACT
Human body temperature detection can be a significant policy for avoiding covid-19 disease spreading in respect of health operations. There are many ways to detect human body temperatures, such as mercury, digital, and infrared thermometers. Internet of Things is widely applied in many aspects, including health care. Many challenging innovations can be studied to enhance temperature monitoring systems. This paper proposes a possible design architecture to implement an IoT Infrared (IR) thermal camera detection. The investigation is performed to observe relative accuracy and distances to detect samples of the human body and object at various temperatures. The LWIR micro thermal camera module is used to detect temperatures comparing to a digital thermometer. The experimentation results show effective detection of IR thermal camera system conditions based on IoT measuring human body temperatures of different distance ranges. However, our research suggests many concerns about using IoT sensors, such as the practical correctness of sensors, types of sensors, and distances of detecting objects. IoT temperature sensors need to be cautiously calibrated to better meet a better effective accuracy compared to a digital thermometer. © 2021 ACM.
ABSTRACT
The pig is one of the economic animals in Thailand. Pork exporting to many countries is significantly higher than the previous year. While Covid-19 disease has arisen severe health problems to cause illness and death in humans worldwide, pork demands in most geographical do not reduce. However, farmers have toughly managed their farms according to fewer local and foreign laborers and social distancing strategy. Recently, IoT technology has been introduced and has been influenced to speedily design and development, helping to sense, monitor, control, and manage tasks automatically. This paper has proposed the design and establishes the automation piggery system to monitor and manage the daily farmer tasks. The automation piggery system has been experienced on the physical piggery for a week. The primary evaluation of the automatic piggery system was investigated to study the functional testing. The system can automatically achieve the basis of daily work schedules of farmers on a traditional piggery. The system monitors times in different periods to check a food quantity and temperature controls for giving water and turning on fans. The software testing includes a precision timing module, data display, and accuracy of IoT particle sensors. However, this research is before being additional needs to research more before the actual deployment can be in a piggery. © 2021 ACM.
ABSTRACT
In the digital age, a transformation of a traditional business to an electronic organization becomes widely general. One of the resolutions is an adopted information technology to design and develop software supporting the whole process of organizations. End users enable to access and use digital services anywhere and anytime. Covid-19 has directed us to face a dramatic death of human life. Social distancing is an announcement of avoiding and touching unknown people, including colleagues, lecturers, and students. In this article, we aim to propose the design and development of a digitally signed document system. The system can handle documents of university processes to advance online forms significantly. By providing the digitally signed document system, a documented strategy can integrate users (e.g., general employees, executives, directors, and lecturers) to send electronic documents with proportional high security. The digital signature of user identification can perform via user identification and verification protocols in many methods. The design and development of software models are approached using rapid application development (RAD). RAD is the most compatible with project factors. The software functionaries of the digitally signed document system are decomposed into components for improving software quality. The interface components deliver indicators of a friendly environment of green information technology as well. © 2021 ACM.
