As the Ministry of Education adds an item to evaluate whether a university strictly manages class time compliance and student attendance, the number of cases in which universities use electronic attendance systems is increasing. If you use the electronic attendance system, you can manage attendance and record management in real time. In this paper, I would like to suggest a solution to the prevention of cheating, which is a problem with the existing electronic attendance system. In this paper, automatic attendance is possible by automatic or correction. If the electronic attendance is performed manually, the BLE beacon service of the professor's smartphone is activated, and then the student's electronic attendance application is automatically executed using the push message service. When the student clicks the attendance check button and the beacon is found, attendance is processed. In the case of automatic processing, the beacon is automatically searched and attendance is handled even if the student is not involved. The proposed system automatically handles attendance even when the student does not recognize it, and has the advantage of preventing illegal attendance because it can reconfirm attendance at unspecified intervals.

Recently, research about an electronic attendance-absence recording system has been actively carried out using smart devices. Using an electronic attendance-absence recording system, professors can check their students' attendance on a real-time basis and manage their attendance records. In this paper, we proposed a real-time electronic attendance-absence recording system using face detection and face recognition based on web application. It can solve the spatial, temporal, cost issues belong to electronic attendance-absence recording system using AIDC(Automatic Identification and Data Capture). A proposed system is running on web server and made by HTML5(Hyper Text Markup Language ver.5). So professor connect to server using mobile web browser on mobile device and real-time manage electronic attendance-absence recording with real-time send or receive image data. In addition, the proposed system has an advantage capable of installation and operation, regardless of the operating system because it operates based on the Python flask framework.

In this paper, we propose an automatic attendance management system for classrooms using OpenCV and machine learning technology. When a face photograph is input at the entrance of the classroom using a general purpose camera for PC, the attendance is checked by comparing the similarity of the face of the already stored student. In this study, the prototype was implemented using the machine learning library dlib, and about 10% of the students had a recognition rate of about 70%.

There are management and price problems that have been caused by requirement of RFID reader, Fingerprint Identification System and Clicker for the construct of automatic attendance system to check the students' attendance accurately and quickly. Therefore, in the thesis, we developed smartphone based attendance check system by utilizing Wi-Fi and the smartphones that has been already built without using additional equipments and establishing construction of system additionally. It recognizes date, time, location and the seat number in classroom if a student logs the attendance chocking application in and it also allows students to get lecture feedback and check attendance by taking quizzes and questionnaires that are related to the lecture. As a result, by applying the attendance check system, instructors state that it is convenient since the app allows instructors to communicate with students though the quizzes and questionnaires. Especially, the instructors state that it is convenient because the results of the quizzes, questionnaires and attendance can be downloaded it the from of Excel files.

Today, using RFID(Radio Frequency Identification) card is extended in diversity as medical treatment, circulation market, military affairs, manufacture, security, etc. The RFID technology is an automatic identification method, relying on storing and remotely retrieving data for the purpose of identification using radio waves. This advantage of the RFID will be as a replacement for traditional Barcoding. Besides, book-lending system and attendance management system become the center of educational institution in interest. This paper presents a attendance management system using the RFID card which provides directly information of attendance for professors with mobile and students with web. Also, the students only have ID card that embed RFID tag which is recognized attendance through DB that storages to is received a information of student from RFID card Reader. And it is possible management or report for attendance and time table not only for professors by management program but also for students by web program.

This paper is about a real-time automatic face recognition system based on one-shot panoramic scanning. It detects multiple faces in real time through a single panoramic scanning process and recognizes pre-registered faces. Instead of recognizing multiple faces within a single panoramic image, multiple faces are recognized using multiple images obtained in the scanning process. This reduces the panorama image creation time and stitching error, and at the same time can improve the face recognition performance by using the accumulated information of multiple images. It is expected that it can be used in various applications such as a multi-person smart attendance system with only a simple image acquisition device.

Currently, the record of part-timer is mainly written in handwriting or using excel work schedule, paper work recorder, and time attendance program using POS program. And, work table, commute records, paycheck are managed separately. Time-attendance information is not linked and is managed separately, and payment of wages is often not done accurately. And, it is difficult to pay the wages because it is not able to accurately grasp the state of attendance of part-timer. Therefore, it is necessary to have a transparent wage and work management system based on the trust between the owner and the part-timer. In this paper, we design a system that can perform real-time commute check using beacon, transparent wage management, wage calculation by automatic calculation, and smooth communication between owner and the part-timer. We have also implemented a store management mobile application using Android Studio 2.3, Eclipse, Android 5.1 and Beacon devices in a MySQL environment.

This study presents a non-video, non-invasive, automatic, on-site monitoring system the system employs ultrasonic transducers to detect behavior in sows before, during and after parturition. An ultrasonic transmitting/receiving (T/R) circuit of 40 kHz was mounted above a conventional parturition bed. The T/R units use ultrasonic time-of-flight (TOF) ranging technology to measure the height of the confined sows at eight predetermined locations. From this data, three momentary postures of the sow are determined, characterized as standing-posture (SP), lateral-lying-posture (LLP) and sitting posture (STP). By examining the frequencies of position switch Stand-Up-Sequence (SUS) between standing-posture (SP), lateral-lying-posture (LLP) and sitting-posture (STP) rate can be determined for the duration of the sow' confinement. Three experimental pureblooded Landrace sows undergoing normal gestation were monitored for the duration of confinement. In agreement with common observation, the sows exhibited increased restlessness as parturition approached. Analysis of the data collected in our study showed a distinct peak in Stand-Up-Sequence (SUS, i.e. the transition from lying laterally to standing up ) and sitting-posture (STP) rate approximately 12 h prior to parturition, the observed peak being 5 to 10 times higher than observed on any other measurement day. It is concluded that the presented methodology is a robust, low-cost, lowlabor method for the continuous remote monitoring of sows and similar large animals for parturition and other behavior. It is suggested that the system could be applied to automatic prediction of sow parturition, with automatic notification of remote management personnel so human attendance at birth could reduce rates of sow and piglet mortality. The results of this study provide a good basis for enhancing automation and reducing costs in large-scale sow husbandry and have applications in the testing of various large mammals for the effects of medications, diets, genetic modifications and environmental factors.
